                 PROPOSED MERGER -- YOUR VOTE IS VERY IMPORTANT

Dear Stockholders:

     On February 23, 2003, Devon Energy Corporation and Ocean Energy, Inc.
agreed to combine their businesses by merging a wholly owned subsidiary of Devon
into Ocean. In the merger, each Ocean stockholder will receive 0.414 of a share
of Devon common stock for each share of Ocean common stock that the stockholder
owns, and Ocean will become a wholly owned subsidiary of Devon. We do not expect
that Ocean common stockholders will recognize any gain or loss for U.S. federal
income tax purposes to the extent that they receive Devon common stock in
exchange for their shares of Ocean common stock.

     The issuance of shares of Devon common stock in the merger requires the
approval of Devon stockholders. In addition, the merger agreement must be
adopted by Ocean stockholders. Devon and Ocean have each scheduled special
meetings of their stockholders to vote on these matters. Regardless of the
number of shares that you own or whether you plan to attend a meeting, it is
important that your shares be represented and voted. Voting instructions are
inside.

     DEVON'S BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED AND ADOPTED THE MERGER
AGREEMENT AND DETERMINED THAT IT IS ADVISABLE AND IN THE BEST INTERESTS OF DEVON
AND ITS STOCKHOLDERS. ACCORDINGLY, DEVON'S BOARD OF DIRECTORS RECOMMENDS THAT
DEVON STOCKHOLDERS VOTE TO APPROVE THE ISSUANCE OF DEVON COMMON STOCK PURSUANT
TO THE MERGER AGREEMENT.

     SIMILARLY, OCEAN'S BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED AND ADOPTED
THE MERGER AGREEMENT AND DETERMINED THAT IT IS ADVISABLE AND IN THE BEST
INTERESTS OF OCEAN AND ITS STOCKHOLDERS. ACCORDINGLY, OCEAN'S BOARD OF DIRECTORS
RECOMMENDS THAT OCEAN STOCKHOLDERS VOTE TO ADOPT THE MERGER AGREEMENT.

     Devon is also proposing to adopt a new long-term incentive plan in
connection with the merger. Adoption of that plan requires the approval of Devon
stockholders. Devon's board of directors recommends that Devon stockholders vote
to adopt the new long-term incentive plan.

     This document provides you with detailed information about the proposed
merger and the new long-term incentive plan that Devon is proposing. We
encourage you to read the entire document carefully.

     Devon's common stock is traded on the American Stock Exchange under the
symbol "DVN." Each share of Devon common stock is accompanied by one right,
issued pursuant to Devon's stockholder rights plan, that trades with the Devon
common stock. In addition, a class of exchangeable shares issued by Devon's
subsidiary, Northstar Energy Corporation, is traded on The Toronto Stock
Exchange under the symbol "NSX." The Northstar exchangeable shares are
exchangeable at any time, on a one-for-one basis, for Devon common stock.
Holders of Devon common stock and Northstar exchangeable shares will vote as a
single class at the Devon meeting.

     Ocean's common stock is traded on the New York Stock Exchange under the
symbol "OEI." Each share of Ocean common stock is accompanied by one right,
issued pursuant to Ocean's stockholder rights plan, that trades with the Ocean
common stock. Ocean's convertible preferred stock is not publicly traded. Ocean
common stockholders and Ocean convertible preferred stockholders will vote as a
single class at the Ocean meeting, with the Ocean convertible preferred
stockholders voting on an as-converted basis.

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q: Why am I receiving these materials?

A: Devon and Ocean have agreed to combine their
   businesses by merging a wholly owned subsidiary of Devon into Ocean. The
   merger cannot be completed without approvals of the stockholders of both
   Devon and Ocean. Devon is also proposing to adopt a new long-term incentive
   plan in connection with the merger that requires approval by Devon
   stockholders.

Q: What will happen to Ocean as a result of the
   merger?

A: A Devon subsidiary will merge with and into
   Ocean, and Ocean will be the surviving company of the merger and a wholly
   owned subsidiary of Devon.

Q: What will Ocean common stockholders receive
   in the merger?

A: Each Ocean common stockholder will receive
   0.414 of a share of Devon common stock for each share of Ocean common stock
   that the stockholder owns at the effective time of the merger. Instead of
   issuing fractional shares to Ocean common stockholders, the exchange agent
   will combine all of the fractional shares and sell them on the American Stock
   Exchange. Ocean common stockholders will receive cash, without interest,
   instead of fractional shares from the proceeds obtained from the sale of
   those shares.

Q:   What will Ocean convertible preferred
   stockholders receive in the merger?

A: Each share of Ocean convertible preferred stock
   outstanding at the effective time of the merger, other than shares held by
   Ocean convertible preferred stockholders who validly exercise their appraisal
   rights under Delaware law, will remain outstanding. After the effective time
   of the merger, those shares of Ocean convertible preferred stock will be
   convertible into Devon common stock instead of Ocean common stock, giving
   effect to the 0.414 exchange ratio, and will have voting rights in Devon on
   an as-converted basis instead of voting rights in Ocean.

Q: Should Ocean stockholders send in their stock
   certificates now?

A:   No. After the merger is completed, Ocean
   common stockholders will receive written instructions for exchanging their
   stock certificates. Please do not send in your Ocean stock certificates with
   your proxy.

Q:   What stockholder approvals are needed to
   complete the merger?

A: The following stockholder approvals are needed
   to complete the merger:

   - the affirmative vote of the holders of at least a majority in interest of
     the voting power of outstanding Ocean common stock to adopt the merger
     agreement, with Ocean convertible preferred stockholders voting on an
     as-converted basis and as a single class with Ocean common stockholders;
     and

   - the affirmative vote of the holders of at least a majority of the votes
     cast in person or by proxy at the Devon meeting to approve the issuance of
     Devon common stock pursuant to the merger agreement.

Q: When do you expect the merger to be completed?

A: We are working to complete the merger as soon
   as possible. A number of conditions must be satisfied before we can complete
   the merger, including approval by the stockholders of both Devon and Ocean.
   Although we cannot be sure when all of the conditions to the merger will be
   satisfied, we expect to complete the merger in the second quarter of 2003.

Q: What do I need to do now?

A: You should carefully read this document. Then,
   if you choose to vote by proxy, you should do so as soon as possible by any
   of the following means: (1) completing, signing and mailing your proxy card,
   (2) using the toll-free telephone number listed on your proxy card and
   following the recorded instructions or (3) going to the Internet website
   listed on your proxy card and following the instructions provided.

                                        i


Q: If I am planning on attending a meeting in
   person, should I still grant my proxy?

A:  Yes. Whether or not you plan to attend a
   meeting, you should grant your proxy as described above. Your shares will not
   be voted if you neither attend a meeting and vote in person nor grant your
   proxy. For Ocean stockholders, this would have the same effect as a vote
   against adoption of the merger agreement. Assuming a quorum is present, the
   failure of a Devon stockholder to vote in person or by proxy will not affect
   the outcome of the matters to be voted on at the Devon meeting.

Q: Can I change my vote after I have granted my
   proxy?

A: Yes. You can change your vote at any time
   before your proxy is voted at the meeting by following the procedures set
   forth in "The Special Meetings -- Voting Procedures -- Revocation" section of
   this document.

Q: If my shares are held in "street name" by my
   broker, will my broker vote my shares for me?

A: Your broker will not vote your shares for or
   against adoption of the merger agreement or the issuance of Devon common
   stock pursuant to the merger agreement unless you tell the broker how to
   vote. If you are a Devon stockholder, your broker may vote your shares for or
   against adoption of the new long-term incentive plan in the broker's
   discretion if you do not tell the broker how to vote. To tell your broker how
   to vote, you should follow the directions that your broker provides to you.

Q: Are any stockholders entitled to appraisal rights
   in connection with the merger?

A: Ocean convertible preferred stockholders who
   comply with the procedures described in "The Merger -- Appraisal Rights"
   section of this document will be entitled to appraisal rights in connection
   with the merger. Devon common stockholders and Ocean common stockholders are
   not entitled to appraisal rights in connection with the merger.

Q: Whom do I call if I have further questions about
   voting, the meetings or the merger?

A: Ocean stockholders may call Ocean's Investor
   Relations department at (713) 265-6161.

   Devon stockholders may call Devon's Investor Relations department at (405)
   552-4570.

     Devon is an independent energy company engaged primarily in oil and natural
gas exploration, development and production, acquisition of producing
properties, transportation of oil, gas and natural gas liquids, or NGLs, and the
processing of natural gas. Devon operates oil and gas properties in the United
States, Canada and internationally. Devon's North American properties are
concentrated within five geographic areas. Operations in the United States are
focused in the Permian Basin, the Mid-Continent, the Rocky Mountains and onshore

THE SPECIAL STOCKHOLDER MEETINGS

  OCEAN SPECIAL STOCKHOLDER MEETING

     Where and when:  The Ocean special stockholder meeting will take place at
          , Houston, Texas, on           , 2003 at           , local time.

     What you are being asked to vote on:  At the Ocean meeting, Ocean

stockholders also may be asked to consider other matters as may properly come
before the meeting. At the present time, Ocean knows of no other matters that
will be presented for consideration at the meeting.

     Who may vote:  You may vote at the Ocean meeting if you owned Ocean common
stock or Ocean convertible preferred stock at the close of business on the
record date,           , 2003. On that date, there were          shares of Ocean

stockholders voting on an as-converted basis. You may cast one vote for each
share of Ocean common stock that you owned on the record date. The number of
votes that you may cast for each share of Ocean convertible preferred stock that
you owned on the record date will be determined by dividing (1) $1,000 plus the
amount of accrued but unpaid dividends per Ocean convertible pre-

                                        1


ferred share by (2) the conversion price of Ocean convertible preferred stock as
of the time of the vote. The Ocean convertible preferred stock conversion price

stockholders will vote on the issuance of Devon common stock pursuant to the
merger agreement and on the adoption of a new long-term incentive plan. Adoption
of the new long-term incentive plan is conditioned on completion of the merger,
but approval of the issuance of Devon common stock pursuant to the merger
agreement is not conditioned on adoption of the new long-term incentive plan.
Devon is seeking adoption of the new long-term incentive plan to accommodate the
larger employee base of the combined company. Devon stockholders also may be
asked to consider other matters as may properly come before the meeting. At the
present time, Devon knows of no other matters that will be presented for
consideration at the meeting.

     Who may vote:  You may vote at the Devon meeting if you owned Devon common
stock or exchangeable shares issued by Devon's subsidiary, Northstar Energy
Corporation, at the close of business on the record date,           , 2003. On
that date, there were           shares of Devon voting stock outstanding and
entitled to vote, consisting of           shares of Devon common stock and
          Northstar exchangeable shares. Holders of Devon common stock and
Northstar exchangeable shares will vote as a single class. You may cast one vote
for each share of Devon common stock and one vote for each Northstar
exchangeable share that you owned on the record date.

     Voting Northstar Exchangeable Shares: Each exchangeable share issued by
Northstar is entitled to one vote at the Devon meeting through a voting
agreement. Under the voting agreement, the trustee exercises voting rights on
behalf of holders of the exchangeable shares. The trustee holds one share of
special voting stock of Devon. The special voting share is entitled to one vote
for each outstanding exchangeable share held by persons other than Devon. The
trustee will vote only as instructed by the holders of exchangeable shares.

     What vote is needed:  The affirmative vote of the holders of at least a
majority of the votes cast in person or by proxy by holders of Devon voting
stock is required to approve the issuance of Devon common stock pursuant to the
merger agreement. The affirmative vote of the holders of at least a majority of
the Devon voting power present in person or by proxy and entitled to vote is
required to adopt the new long-term incentive plan.

WHAT OCEAN STOCKHOLDERS WILL RECEIVE IN THE MERGER

     Each Ocean common stockholder will receive 0.414 of a share of Devon common
stock for each share of Ocean common stock that the stockholder owns at the
effective time of the merger. Instead of issuing fractional shares to Ocean
common stockholders, the exchange agent will combine all of the fractional
shares and sell them on the American Stock Exchange. Ocean common stockholders
will receive cash, without interest, instead of fractional shares from the
proceeds obtained from the sale of those shares.

     Each share of Ocean convertible preferred stock outstanding at the
effective time of the merger, other than shares held by Ocean convertible
preferred stockholders who validly exercise their appraisal rights under
Delaware law, will remain outstanding. After the effective time of the merger,
those shares of Ocean convertible preferred stock will be convertible into Devon
common stock instead of Ocean common stock, giving effect to the 0.414 exchange
ratio, and will have voting rights in Devon on an as-converted basis instead of
voting rights in Ocean.

                                        2


U.S. FEDERAL INCOME TAX CONSEQUENCES

     The merger has been structured so that none of Ocean, Devon or their
respective common stockholders will recognize any gain or loss for U.S. federal
income tax purposes, except to the extent that Ocean common stockholders receive
cash instead of fractional shares of Devon common stock. As a condition to the
merger, Devon and Ocean must each receive a satisfactory opinion from their own
legal counsel regarding the U.S. federal income tax treatment of the merger.

     The federal income tax consequences of the merger to Ocean convertible
preferred stockholders are not clear. As discussed more fully in the "Material
Federal Income Tax Considerations -- Tax Treatment of Ocean Convertible
Preferred Stockholders" section of this document, it is possible that the
Internal Revenue Service could assert either (1) that the automatic
substitution, at the effective time of the merger, of Devon common stock for
Ocean common stock would cause a taxable exchange resulting in recognition of
gain or loss for Ocean convertible preferred stockholders or (2) that a
subsequent conversion of the Ocean convertible preferred stock would be a
taxable transaction on which gain or loss would be recognized.

     Tax matters are very complicated. The tax consequences of the merger to you
will depend on your own situation. We urge that you consult your tax advisor for
a full understanding of the U.S. federal, state, local and foreign tax
consequences of the merger to you.

DIRECTORS AND MANAGEMENT OF DEVON FOLLOWING THE MERGER

     Devon's board of directors is expected to consist of 13 directors after the
effective time of the merger. In that case, nine members of Devon's current
board of directors will retain their positions, and four members of Ocean's
board of directors will be appointed as new members of Devon's board of
directors at the effective time of the merger.

     J. Larry Nichols, currently the Chairman, President and Chief Executive
Officer of Devon, will remain the Chairman and Chief Executive Officer of Devon.
James T. Hackett, currently the Chairman, President and Chief Executive Officer
of Ocean, will become the President and Chief Operating Officer of Devon at the
effective time of the merger. Devon expects that management of the combined
company will consist of Devon and Ocean employees.

OUR RECOMMENDATIONS TO STOCKHOLDERS

  TO OCEAN STOCKHOLDERS:

     Ocean's board of directors has unanimously approved and adopted the merger
agreement and determined that it is in the best interests of Ocean and its
stockholders. Accordingly, the board recommends that Ocean stockholders vote to
adopt the merger agreement.

     As of           , 2003, shares representing about 4% of the voting
interests of outstanding Ocean stock were held by Ocean's directors, executive
officers and their respective affiliates.

  TO DEVON STOCKHOLDERS:

     Devon's board of directors has unanimously approved and adopted the merger
agreement and determined that it is advisable and in the best interests of Devon
and its stockholders. Devon's board of directors also has unanimously approved
the new long-term incentive plan. Accordingly, the board recommends that Devon
stockholders vote to approve the issuance of Devon common stock pursuant to the
merger agreement and to adopt the new long-term incentive plan.

                                        3


     As of           , 2003, about 2% of Devon's outstanding voting shares were
held by Devon's directors, executive officers and their respective affiliates.

OCEAN'S REASONS FOR THE MERGER

     Ocean's board of directors considered various factors in approving and
adopting the merger agreement, including the complementary assets of Ocean and
Devon, the pro forma financial profile of the combined company, expected
benefits from the increased size of the combined company, opportunities to
invest Devon's excess operating cash flow to fund Ocean's significant
exploration and development projects, the accretion to Ocean stockholders in
cash flow per share that Ocean expects to result from the merger, the 0.414
exchange ratio, the tax consequences of the merger to Ocean stockholders and the
other matters referred to in the "The Merger -- Recommendations of Ocean's Board
of Directors and Reasons for the Merger" section of this document.

DEVON'S REASONS FOR THE MERGER

     Devon's board of directors considered various factors in approving and
adopting the merger agreement, including opportunities to invest Devon's excess
operating cash flow to fund Ocean's significant exploration and development
projects, the substantial overlap between areas in which Devon and Ocean
operate, the decrease in the combined company's total debt to capitalization as
compared to Devon's stand-alone total debt to capitalization, the 0.414 exchange
ratio, expected near-term benefits from Ocean's existing operations, expected
benefits from the increased size of the combined company and the other matters
referred to in the "The Merger -- Recommendations of Devon's Board of Directors
and Reasons for the Merger" section of this document.

INTERESTS OF OCEAN'S EXECUTIVE OFFICERS AND DIRECTORS IN THE MERGER

     Some of Ocean's directors and executive officers may have interests in the
merger that are different from, or are in addition to, your interests:


- At the effective time of the merger,           ,           ,           and
            , each of whom is currently a member of Ocean's board of directors,
  are expected to be appointed to Devon's board of directors. Each will serve
  until his successor is elected and qualified or until his earlier resignation
  or removal.

- At the effective time of the merger, James T. Hackett, who is currently
  Ocean's Chairman, President and Chief Executive Officer, will be appointed
  President and Chief Operating Officer of Devon. Mr. Hackett's existing
  employment and severance agreements were amended in connection with the merger
  agreement to suspend until May 1, 2004 the triggering of certain
  change-of-control provisions that otherwise would have permitted Mr. Hackett
  to terminate his employment at or after the effective time of the merger and
  receive certain severance payments.

- After the merger, some Ocean officers may become officers of Devon.

- Outstanding Ocean stock options and restricted stock awards held by Ocean's
  directors and executive officers (and all other Ocean employees) will vest at
  the effective time of the merger. Outstanding Ocean stock options not
  exercised at that time will be converted into options to purchase shares of
  Devon common stock, subject to adjustment for the 0.414 exchange ratio.

- The merger will trigger change-of-control provisions in the employment
  agreements of some of Ocean's officers, which may entitle them to severance
  benefits if their employment ceases after the merger.

- Those Ocean directors who are not appointed to the Devon board will be
  entitled to lump-sum cash payments and other benefits having an aggregate
  value of about $1.4 million under Ocean's existing directors compensation
  plan.

- The merger will cause full or partial vesting of outstanding awards under
  Ocean's executive supplemental retirement plan, in which some of Ocean's
  executive officers participate, if a participant is terminated under some
  circumstances.

- The merger agreement generally requires Devon to honor Ocean's existing
  employee benefit plans and commitments in accordance with their terms after
  the merger.

- After the merger, Ocean will indemnify and hold harmless to the fullest extent
  permitted under law each current and former director and

                                        4


  officer of Ocean, its subsidiaries and divisions against all losses pertaining
  to actions taken by them, or failures to act, while serving in those
  capacities before the merger.

- For six years after the merger, Ocean will maintain its current policies of
  directors' and officers' liability insurance and fiduciary liability
  insurance, or policies no less favorable to the insured, covering acts or
  omissions before the merger.

     Ocean's directors and executive officers beneficially owned about 4% of the
voting interests of outstanding Ocean stock as of           , 2003. Devon's
directors and executive officers did not beneficially own any shares of Ocean
stock as of           , 2003.

     The boards of directors of both companies were aware of these interests and
considered them in approving the merger agreement.

OPINIONS OF FINANCIAL ADVISORS

     The opinions of Ocean's and Devon's financial advisors are attached to this
document as Annexes B and C. We encourage you to read those opinions carefully,
as well as the descriptions of the analyses and assumptions on which the
opinions were based in "The Merger -- Opinions of Financial Advisors" section of
this document. Each opinion is directed to the applicable company's board of
directors and does not constitute a recommendation to any stockholder as to any
matter relating to the merger.

  OPINION OF OCEAN'S FINANCIAL ADVISOR

     Deutsche Bank Securities Inc., Ocean's financial advisor, delivered its
opinion to Ocean's board of directors on February 23, 2003 to the effect that,
as of the date of its opinion and subject to the matters and assumptions set
forth in the opinion, the 0.414 exchange ratio was fair from a financial point
of view to Ocean common stockholders.

  OPINION OF DEVON'S FINANCIAL ADVISOR

     Morgan Stanley & Co. Incorporated, Devon's financial advisor, delivered its
opinion to Devon's board of directors on February 23, 2003 to the effect that,
as of the date of its opinion and subject to the matters and assumptions set
forth in the opinion, the 0.414 exchange ratio pursuant to the merger agreement
was fair from a financial point of view to Devon.

THE MERGER AGREEMENT

     The merger agreement is attached to this document as Annex A. We encourage
you to read the merger agreement because it is the legal document that governs
the merger.

  WHAT WE NEED TO DO TO COMPLETE THE MERGER

     Devon and Ocean will complete the merger only if the conditions set forth
in the merger agreement are satisfied or, in some cases, waived. These
conditions include:

     - adoption by Ocean's stockholders of the merger agreement;

     - approval by Devon's stockholders of the issuance of Devon common stock
       pursuant to the merger agreement;

     - the expiration of applicable antitrust waiting periods or the receipt of
       necessary antitrust approvals;

     - the absence of legal prohibitions to the merger;

     - the continued effectiveness of the registration statement of which this
       document is a part;

     - the approval for listing on the American Stock Exchange of the shares of
       Devon common stock to be issued in the merger;

     - the continued accuracy of each company's representations and warranties;

     - the performance by each company of its obligations under the merger
       agreement; and

     - the receipt of legal opinions from counsel for each company as to the
       treatment of the merger for U.S. federal income tax purposes.

     Either Devon or Ocean may choose to complete the merger even though a
condition to its obligations has not been satisfied if the necessary stockholder
approvals have been obtained and the law allows the company to do so.

                                        5


  TERMINATION OF THE MERGER AGREEMENT

     Devon and Ocean can agree to terminate the merger agreement at any time
without completing the merger, even after stockholder approvals have been
obtained. In addition, either company can terminate the merger agreement on its
own without completing the merger if:

     - the merger is not completed by September 30, 2003, other than due to a
       breach of the merger agreement by the terminating company;

     - the necessary approval of the stockholders of either company is not
       obtained at their respective meetings;

     - any legal prohibition to completing the merger has become final and non-
       appealable;

     - the other company materially breaches the merger agreement and cannot or
       does not correct the breach within a 30-day cure period;

     - the board of directors of the other company withdraws or adversely
       changes its original recommendation of the merger, or recommends that its
       stockholders vote for a competing transaction; or

     - its own board of directors withdraws or adversely changes its original
       recommendation of the merger, or recommends that stockholders vote for a
       competing transaction, and the other company does not require that it
       submit the matter to be voted on at its meeting to a vote of its
       stockholders.

  TERMINATION FEES AND EXPENSES

     If the merger agreement is terminated under circumstances involving a
proposed business transaction between either Devon or Ocean and a third party
that conflicts with the merger and other conditions are satisfied, either Devon
or Ocean will be required to pay a termination fee of up to $139 million and
reimburse the other party for up to $10 million of expenses incurred by the
other party in connection with the merger agreement.

  OPTION TO REQUIRE OTHER PARTY'S
  STOCKHOLDER VOTE

     Each company will have an option, exercisable within two business days
after it receives written notice from the other party that the other party's
board of directors has withdrawn or adversely changed its original
recommendation or recommended a competing transaction to its stockholders, to
require the other party to (1) submit to a vote the matter to be voted on by
that party's stockholders and (2) disclose to that party's stockholders the
circumstances under which the matter is being submitted to a vote.

  NO SOLICITATION

     Devon and Ocean have generally agreed not to initiate or continue any
discussions with any other party regarding a business combination while the
merger is pending or to engage in any of those discussions unless required by
fiduciary obligations under applicable law.

OTHER INFORMATION RELATED TO THE MERGER

  PENDING LITIGATION

     A lawsuit was filed on February 27, 2003 against Ocean and all of the
members of Ocean's board of directors. The complaint seeks class action status
and alleges breach of fiduciary duty in connection with the approval of the
merger agreement by Ocean's board of directors. Ocean believes that the lawsuit
is without merit and intends to defend against it vigorously. We can provide no
assurance that additional claims may not be made or filed arising out of, or
relating to, the merger agreement or the transactions that it contemplates.

  ANTITRUST CLEARANCE REQUIRED TO COMPLETE THE MERGER

     The merger is subject to antitrust laws. We made the required filings with
the Department of Justice and the Federal Trade Commission relating to the
merger on           , 2003, but we are not permitted to complete the merger
until the applicable waiting periods have expired or otherwise terminated. We
expect that the applicable waiting periods will expire on or about           ,
2003. Although we do not expect the federal government or any state government
to attempt to

                                        6


stop the merger, we cannot assure you that they will not try to do so.

  LISTING OF COMMON STOCK TO BE ISSUED IN THE MERGER

     Devon expects to obtain approval to list on the American Stock Exchange the
shares of Devon common stock to be issued pursuant to the merger agreement.

  APPRAISAL RIGHTS

     Devon stockholders and Ocean common stockholders are not entitled to
appraisal rights in connection with the merger. Ocean convertible preferred
stockholders are entitled to appraisal rights in accordance with Delaware law.
See "The Merger -- Appraisal Rights" section of this document for more
information regarding the appraisal rights of Ocean convertible preferred
stockholders.

  ACCOUNTING TREATMENT

     Devon will account for the merger using the purchase method of accounting.
Under that method of accounting, the aggregate consideration that Devon pays to
Ocean stockholders will be allocated to Ocean's assets and liabilities based on
their fair values, with any excess being treated as goodwill. Devon currently
expects to record approximately $1.3 billion of goodwill, but that estimate is
subject to change.

DEVON ENERGY CORPORATION 2003 OMNIBUS LONG-TERM INCENTIVE PLAN

     On February 22, 2003, Devon's board of directors approved the Devon Energy
Corporation 2003 Omnibus Long-Term Incentive Plan, which we sometimes refer to
in this document as the "new long-term incentive plan" or the "plan," subject to
adoption of the plan by Devon stockholders and to completion of the merger. The
new long-term incentive plan is intended, among other things, to help the
combined company attract and retain directors and employees after the effective
time of the merger and to encourage them to promote the growth and profitability
of the combined company.

     This information is only a summary. You should read the unaudited pro forma
combined financial information and the accompanying notes that are included in
this document. You should also read the historical information of Devon and
Ocean that is incorporated by reference into this document.

     We are providing the unaudited pro forma combined condensed financial and
other data for informational purposes only. It does not purport to represent
what the financial position and results of operations of the combined company
would actually have been had the merger in fact occurred on the dates indicated.
It also does not purport to represent the future results that the combined
company will achieve after the merger.

     We prepared the pro forma information based on the following:

     - Both Devon and Ocean use the full cost method of accounting for their oil
       and gas producing activities.

     - Devon acquired all the outstanding common shares of Mitchell Energy &
       Development Corp. on January 24, 2002. Devon's operating results for 2002
       included in the unaudited pro forma combined statement of operations
       assume that the Mitchell acquisition occurred on January 1, 2002.

     - We have not reflected as an adjustment to the historical data annual cost
       savings of at least $50 million that Devon and Ocean expect to result
       from the merger.

     - Devon recognized net earnings from discontinued operations in 2002 of $45
       million. This gain is not included in the summary unaudited pro forma
       combined statement of operations.

     No pro forma adjustments have been made with respect to the following
unusual items. These items are reflected in the historical results of Devon and
Ocean, as applicable, and should be considered in reading the pro forma results:

     - In the second quarter of 2002, Devon recognized a $651 million ($371
       million after tax) reduction to the carrying value of its Canadian oil
       and gas properties pursuant to the full cost accounting ceiling rules.

     - In the third quarter of 2002, Ocean announced that it would discontinue
       current exploratory activities in Pakistan and on Block 10 offshore
       Angola. As a result, Ocean recognized an impairment in the amount of $76
       million ($50 million after tax).

     - In the fourth quarter of 2002, Devon recognized a $205 million ($128
       million after tax) expense related to the impairment of the value of 7.1
       million shares of ChevronTexaco Corporation common stock owned by Devon.
       The impairment was related to Devon's determination that the decline in
       the value of the ChevronTexaco common stock was other than temporary, as
       such term is defined by accounting rules.

                                  RISK FACTORS

     You should consider carefully the following risk factors before deciding
how to vote.

WE MAY NOT BE ABLE TO INTEGRATE THE OPERATIONS OF DEVON AND OCEAN SUCCESSFULLY

     The merger will present challenges to management, including the integration
of the operations, technologies and personnel of Devon and Ocean. The merger
will also include other risks commonly associated with similar transactions,
including unanticipated liabilities, unanticipated costs and diversion of
management's attention. Any difficulties that we encounter in the transition and
integration process could have an adverse effect on the revenue, level of
expenses and operating results of the combined company. The combined company may
also experience operational interruptions or the loss of key employees,
customers or suppliers. As a result, we may not realize any of the anticipated
benefits of the merger.

THE MARKET VALUE AT THE EFFECTIVE TIME OF THE MERGER OF THE CONSIDERATION TO
OCEAN STOCKHOLDERS IS DETERMINED BY THE PRICE OF DEVON COMMON STOCK; THE MARKET
VALUE WILL DECREASE IF THE MARKET VALUE OF DEVON COMMON STOCK DECREASES

     The market value at the effective time of the merger of the consideration
that Ocean stockholders will receive in the merger depends on the trading price
of Devon common stock. The 0.414 exchange ratio that determines the number of
shares of Devon common stock that Ocean stockholders will receive in the merger
is fixed. This means that there is no "price protection" mechanism contained in
the merger agreement that would adjust the number of shares that Ocean
stockholders will receive based on any increases or decreases in the trading
price of Devon common stock. If Devon's stock price decreases, the market value
of the consideration will also decrease. For historical and current market
prices of Devon common stock and Ocean common stock, see the "Market Prices and
Dividend Information" section of this document.

THE MERGER MAY BE DILUTIVE TO VARIOUS FINANCIAL MEASUREMENTS

     Devon expects that, in the near term, the merger will be slightly dilutive
to its earnings per share, cash flow per share, production per share and
reserves per share on a pro forma basis. Future events and conditions could
cause such dilution to be more significant than expected, including, among other
things, adverse changes in:

     - energy market conditions;

     - commodity prices for oil, natural gas and NGLs;

     - anticipated production levels;

     - anticipated reserve levels;

     - future operating results;

     - competitive conditions;

     - the effectiveness of technologies;

     - the availability of capital resources;

     - laws and regulations affecting the energy business;

     - capital expenditure obligations; and

     - general economic conditions.

THE COMBINED COMPANY MAY REQUIRE CAPITAL OUTLAYS IN EXCESS OF ITS CASH FLOW

     The benefits that Devon and Ocean expect from the merger may be reduced if
the combined company's cash flow is insufficient to meets its capital needs.
Devon and Ocean have a significant number

                                        13


of proved undeveloped reserves, or PUDs, international drilling commitments and
deepwater projects and prospects. The capital outlays necessary to achieve the
anticipated benefits of those assets will be significant. In addition, the
combined company will have significant debt maturities over the next several
years. If the combined company's operating cash flow is insufficient to meet
those outlays, we may need to reduce or reprioritize our capital budget, or sell
non-core assets, "monetize" commercial discoveries that would be capital
intensive or access the capital markets to obtain the necessary funds. A
significant decline in commodity prices would make it even more difficult to
fund those projects at the times required.

OIL AND GAS OPERATIONS INVOLVE SUBSTANTIAL COSTS AND ARE SUBJECT TO VARIOUS
ECONOMIC RISKS

     The oil and gas operations of Devon and Ocean are, and the oil and gas
operations of the combined company will be, subject to the economic risks
typically associated with exploration, development and production activities,
including the necessity of significant expenditures to locate and acquire
properties and to drill exploratory wells. In conducting exploration,
development and production activities, the occurrence of some events can cause
damage to property, interrupt production or otherwise compromise the combined
company's operations. These risks include:

     - the presence of unanticipated pressure or irregularities in formations;

     - weather disturbances;

     - lack of access to pipelines or other methods of transportation;

     - accidents, blowouts or similar events; or

     - environmental hazards or liabilities.

     A significant occurrence of one of these events could result in a total
loss of the combined company's investment in a particular property. If
exploration efforts are unsuccessful in establishing proved reserves and
exploration activities cease, the amounts accumulated as unproved costs would be
charged against earnings as impairments in countries where the existence of
proved reserves has not yet been determined. In addition, the cost and timing
associated with drilling, completing and operating wells is often uncertain.

DEVON AND OCEAN ARE, AND THE COMBINED COMPANY WILL BE, SUBJECT TO UNCERTAINTIES
OF FOREIGN OPERATIONS

     Devon has international operations in Azerbaijan, Brazil, China and West
Africa. Ocean has numerous international assets in Equatorial Guinea, Angola,
Nigeria, Cote d'Ivoire, Egypt, the Russian Republic of Tatarstan, Brazil and
Indonesia that will expose the combined company to additional uncertainties.
Political, economic and other uncertainties may adversely affect these
operations. These uncertainties include:

     - general strikes and civil unrest;

     - the risk of war, acts of terrorism, expropriation, forced renegotiation
       or modification of existing contracts;

     - import and export regulations;

     - taxation policies, including royalty and tax increases and retroactive
       tax claims, and investment restrictions;

     - transportation regulations and tariffs;

     - exchange controls, currency fluctuations, devaluation or other activities
       that limit or disrupt markets and restrict payments or the movement of
       funds;

     - laws and policies of the United States affecting foreign trade, including
       trade sanctions;

     - the possibility of being subject to exclusive jurisdiction of foreign
       courts in connection with legal disputes relating to licenses to operate
       and concession rights in countries where Devon and Ocean currently
       operate;

                                        14


     - the possible inability to subject foreign persons to the jurisdiction of
       courts in the United States; and

     - difficulties in enforcing the combined company's rights against a
       governmental agency because of the doctrine of sovereign immunity and
       foreign sovereignty over international operations.

     Foreign countries have occasionally asserted rights to land, including oil
and gas properties, through border disputes. If a country claims superior rights
to oil and gas leases or concessions granted to Devon or Ocean by another
country, Devon's or Ocean's interests could decrease in value or be lost. Even
the combined company's smaller international assets may affect our overall
business and results of operations by distracting management's attention from
our more significant assets. Various regions of the world have a history of
political and economic instability. This instability could result in new
governments or the adoption of new policies that might assume a substantially
more hostile attitude toward foreign investment. In an extreme case, such a
change could result in termination of contract rights and expropriation of
foreign-owned assets. This could adversely affect the combined company's
interests.

REPORTED OIL, NATURAL GAS AND NGL RESERVE DATA AND FUTURE NET REVENUE ESTIMATES
ARE UNCERTAIN

     Estimates of reserves are projections based on engineering data, projected
future rates of production and the timing of future expenditures. Devon's
estimates of its proved oil, natural gas and NGL reserves and projected future
net revenue are based on reserve reports that Devon prepares and on the reports
of independent consulting petroleum engineers that it hires for that purpose.
Ocean's estimates of proved oil and natural gas reserves and projected net
revenue are based on reports prepared by internal reserve engineers. At least
80% of Ocean's estimates of proved reserves are reviewed annually by an
independent petroleum engineering firm. The process of estimating oil, natural
gas and NGL reserves requires substantial judgment, resulting in imprecise
determinations, particularly for new discoveries. Different reserve engineers
may make different estimates of reserve quantities and related revenue based on
the same data. Future performance that deviates significantly from the reserve
reports could have a material adverse effect on the combined company's financial
position and results of operations.

PRODUCT PRICES ARE VOLATILE, AND LOW PRICES CAN ADVERSELY IMPACT RESULTS

     The results of operations of Devon and Ocean are highly dependent on the
prices of and demand for oil, natural gas and NGLs. Historically, the markets
for oil, natural gas and NGLs have been volatile and are likely to continue to
be volatile in the future. Accordingly, the prices received by Devon and Ocean
for their oil, natural gas and NGL production depend on numerous factors beyond
their control. These factors include, among other things:

     - the level of ultimate consumer product demand;

     - governmental regulations and taxes;

     - the price and availability of alternative fuels;

     - the level of imports and exports of oil, natural gas and NGLs;

     - the overall economic environment;

     - OPEC production restraints; and

     - weather.

Any significant decline in prices for oil, natural gas and NGLs, as has occurred
from time to time in the past, could have a material adverse effect on the
combined company's financial condition, results of operations and quantities of
reserves recoverable on an economic basis. Should the oil and gas industry
experience significant price declines or other adverse market conditions, the
combined company may not be able to generate sufficient cash flows from
operations to meet its obligations and to make planned capital expenditures.

                                        15


CONCESSIONS GRANTED TO DEVON AND OCEAN BY FOREIGN COUNTRIES WILL REQUIRE
SIGNIFICANT CAPITAL OUTLAYS WITHOUT GUARANTEED RESULTS

     Devon and Ocean have made commitments in connection with being granted
concessions by foreign countries that will require the combined company to make
significant capital outlays. The benefits that Devon and Ocean anticipate from
those commitments may not be realized. It would likely be difficult for the
combined company to exit some or all of those countries without making those
capital outlays.

OCEAN'S SIGNIFICANT INVESTMENT IN SEVERAL HIGH VOLUME ASSETS MAY NOT GENERATE
THE BENEFITS EXPECTED BY DEVON

     Devon believes that a significant portion of Ocean's value and future
potential is tied to several of its high volume assets, including the Zafiro
Field in Equatorial Guinea and six significant deepwater discoveries in the Gulf
of Mexico. These projects currently account for about 40% of Ocean's current
reserves. To the extent that these assets do not generate the return expected of
them, the benefits of the merger to Devon will be reduced and the combined
company may have to write down the related reserves.

TERRORIST ATTACKS OR SIMILAR HOSTILITIES MAY ADVERSELY IMPACT OUR RESULTS OF
OPERATIONS

     The impact that future terrorist attacks or regional hostilities
(particularly in the Middle East) may have on the energy industry in general,
and on Devon, Ocean and the combined company in particular, is not known at this
time. Uncertainty surrounding military strikes or a sustained military campaign
may affect operations in unpredictable ways, including disruptions of fuel
supplies and markets, particularly oil, and the possibility that infrastructure
facilities, including pipelines, production facilities, processing plants and
refineries, could be direct targets of, or indirect casualties of, an act of
terror or war. Moreover, each of Devon and Ocean have incurred additional costs
since the terrorist attacks of September 11, 2001 to safeguard certain of its
assets, and the combined company may be required to incur significant additional
costs in the future.

THE COMBINED COMPANY'S DEBT LEVEL MAY LIMIT ITS FINANCIAL FLEXIBILITY

     As of December 31, 2002, Devon had approximately $7.6 billion of total
debt. As of the same date, Ocean had approximately $1.4 billion of total debt.
Assuming that the merger had been completed on December 31, 2002, the combined
company would have had approximately $9.2 billion of total debt on a pro forma
basis. The combined company may incur additional debt in the future, including
debt in connection with future acquisitions. The level of the combined company's
debt could have several important effects on the combined company's future
operations, including, among other things:

     - a significant portion of the combined company's cash flow from operations
       will be dedicated to the payment of principal and interest on outstanding
       debt and will not be available for other purposes;

     - credit rating agencies may in the future view the combined company's debt
       level negatively;

     - covenants contained in Devon's and Ocean's existing debt arrangements
       will require the combined company to continue to meet financial tests
       that may affect the combined company's flexibility in planning for and
       reacting to changes in its business, including possible acquisition
       opportunities;

     - the combined company's ability to obtain additional financing for working
       capital, capital expenditures, acquisitions, general corporate and other
       purposes may be limited;

     - the combined company may be at a competitive disadvantage to similar
       companies that have less debt; and

     - the combined company may be more vulnerable to adverse economic and
       industry conditions as a result of its significant debt level.

                                        16


                                 THE COMPANIES

OCEAN ENERGY, INC.

     Ocean is an independent energy company engaged primarily in oil and natural
gas exploration, development and production, and the acquisition of producing
properties. Ocean conducts North American operations in the shelf and deepwater
areas of the Gulf of Mexico, the Rocky Mountains, the Permian Basin, Anadarko,
East Texas, North Louisiana and the Gulf Coast regions. Internationally, Ocean
conducts oil and gas activities in Equatorial Guinea, Angola, Nigeria and Cote
d' Ivoire. Ocean also conducts operations in Egypt, the Russian Republic of
Tatarstan, Brazil and Indonesia.

     Ocean has developed a significant position among U.S. independent oil and
gas exploration and production companies in the deep waters off the coasts of
the Gulf of Mexico, Brazil and West Africa. Ocean has assumed an operator
position as controlling partner on selected properties in each of these
deepwater areas. During 2002, Ocean increased its deepwater net acreage position
in the Gulf of Mexico and expanded its international operations by adding new
blocks in Angola, Nigeria and Egypt.

     At December 31, 2002, Ocean's estimated proved reserves were 593 MMBoe, of
which 50% were natural gas reserves and 50% were oil and NGL reserves. The
present value of pre-tax net revenues discounted at 10% per annum assuming
essentially constant prices of these reserves was $6.4 billion. After taxes, the
present value was $4.7 billion.

DEVON ENERGY CORPORATION

     Devon is an independent energy company engaged primarily in oil and natural
gas exploration, development and production, acquisition of producing
properties, transportation of oil, gas and NGLs and the processing of natural
gas. Through its predecessors, Devon began operations in 1971. Devon operates
oil and gas properties in the United States, Canada and internationally. Devon's
North American properties are concentrated within five geographic areas.
Operations in the United States are focused in the Permian Basin, the
Mid-Continent, the Rocky Mountains and onshore and offshore Gulf Coast. Canadian
operations are focused in the Western Canadian Sedimentary Basin in Alberta and
British Columbia. Operations outside North America currently include Azerbaijan,
Brazil, China and West Africa.

     In addition to its exploration and production activities, Devon has a
marketing and midstream business. The marketing business is responsible for the
marketing of Devon's natural gas, crude oil and NGLs. The midstream business
transports oil and gas, removes impurities and extracts NGLs from the natural
gas stream for separate sale. The midstream business is also responsible for
construction and operation of Devon's pipelines, storage and treatment
facilities and gas processing plants.

     At December 31, 2002, Devon's estimated proved reserves were 1,609 MMBoe,
of which 60% were natural gas reserves and 40% were oil and NGLs reserves. The
present value of pre-tax future net revenues discounted at 10% per annum
assuming essentially constant prices of those reserves was $15.3 billion. After
taxes, the present value was $10.4 billion.

PRIMARY OPERATING AREAS

     Eighty-four percent of the combined company's proved reserves will be
within North America. The remainder is in several other regions. Devon has
organized its exploration and production operations geographically into five
separate areas in North America and one internationally. Devon also has a
separate marketing and midstream business.

                                        18


     Ocean's operations are also organized geographically into three separate
areas. Each area includes an underlying base of producing oil and gas wells and
an inventory of undeveloped lands on which to explore for new oil and gas
reserves.

DEVON'S PROPERTIES

     Devon's North American properties are concentrated within five geographic
areas. Operations in the United States are focused in the Permian Basin, the
Mid-Continent, the Rocky Mountains and onshore and offshore Gulf Coast regions.
Canadian operations are focused in the Western Canadian Sedimentary Basin in
Alberta and British Columbia. Operations outside North America currently include
Azerbaijan, Brazil, China and West Africa. Maintaining a tight geographic focus
in selected core areas has allowed Devon to improve operating and capital
efficiency.

  UNITED STATES PROPERTIES

  Permian Basin

     The Permian Basin includes portions of Southeast New Mexico and West Texas.
These assets include conventional oil and gas properties from a wide variety of
geologic formations and productive depths. The Permian Basin represented 9% of
Devon's proved reserves at December 31, 2002.

     Devon's leasehold position in Southeast New Mexico encompasses more than
102,000 acres of developed lands and 237,000 acres of undeveloped land and
minerals. Historically, Devon has been a very active operator in this area
developing gas from the high productivity Morrow formation and oil in the lower
risk Delaware formation.

     In the West Texas area of the Permian Basin, Devon maintains a base of oil
production with long-life reserves. Many of these reserves are from both
operated and non-operated positions in large enhanced oil recovery units such as
the Wasson ODC Unit, the Willard Unit, the Reeves Unit, the North Welch Unit and
the Anton Irish (Clearfork) Unit. These oil-producing units often exhibit long
lives with low decline rates. Devon also owns a significant acreage position in
West Texas with over 194,000 acres of developed lands and over 224,000 acres of
undeveloped land and minerals at December 31, 2002.

  Mid-Continent

     The Mid-Continent region includes portions of Texas, Oklahoma, Kansas,
Mississippi and Louisiana. These areas encompass a wide variety of geologic
formations and productive depths and produce both oil and natural gas. Devon's
Mid-Continent production has historically come from conventional oil and gas
properties, but Devon has recently established two non-conventional gas
operations in the Mid-Continent region: the Barnett Shale and the Cherokee
coalbed methane project. The Mid-Continent region represented 30% of Devon's
proved reserves at December 31, 2002.

     The most significant asset acquired by Devon in its 2002 acquisition of
Mitchell was a substantial interest in the Barnett Shale of North Texas. The
Barnett Shale is known as a tight gas formation. This means that, in its natural
state, the formation is resistant to the production of natural gas. Mitchell
spent decades understanding how to efficiently develop and produce this gas. The
resulting technology yielded a low-risk and highly profitable natural gas
operation. Devon holds 525,000 net acres and over 1,100 producing wells in the
Barnett Shale. Devon's average working interest is approximately 95%. The
Barnett Shale is a unique, unconventional natural gas resource that offers
immediate low-risk production growth and the potential for additional drilling
locations.

     Devon has experienced success extracting gas from the Barnett Shale by
using light sand fracturing. Light sand fracturing yields better results than
earlier techniques and is less expensive and can be used to complete new wells
and to refracture existing wells. Refractured wells often exceed their original
flow rates. Devon is also investigating horizontal drilling and closer well
spacing to further enhance the value of the Barnett Shale.

                                        19


     Devon's marketing and midstream operation transports, treats and processes
its Barnett Shale production along with Barnett Shale production from unrelated
third parties. The transport system consists of approximately 3,100 miles of
pipeline, a 650 MMcf per day gas processing plant, and a 15,000 Bbls per day NGL
fractionator.

     In 2003, Devon plans to drill up to 450 new Barnett Shale wells and
refracture 64 wells. Devon is also conducting exploratory pilot projects outside
the core development area in an effort to expand the productive area. The
Barnett Shale is expected to continue to be an important growth area for Devon
for the foreseeable future. Current production from the Barnett Shale is
approximately 345 MMcf and 21,700 Bbls of oil and NGLs per day net.

     The other non-conventional asset Devon is developing in the Mid-Continent
region is the Cherokee coalbed methane project. Coalbed methane is natural gas
produced from underground coal deposits. Devon acquired over 400,000 net acres
within the Cherokee area of Southeast Kansas and Northeast Oklahoma in 2001.

     Devon's East Texas properties are a significant conventional asset. A large
portion of this asset base was initially acquired in 1999. The Carthage and
Bethany fields are two of the primary properties. These properties produce from
the Cotton Valley sands, the Travis Peak sands and from shallower sands and
carbonates. Devon operates over 500 producing wells in this area and utilizes a
one to two rig drilling program to continue the low-risk, infill development of
this area.

     The 2002 acquisition of Mitchell added a complementary asset base to the
East Texas area. These properties are located on the western side of the East
Texas Basin and produce from the Bossier, Cotton Valley and Travis Peaks sands.
Devon operates approximately 400 producing wells in this area and plans to
continue the development drilling program with one to two rigs. Devon's current
net production in East Texas is approximately 123 MMcf and 3,800 Bbls of oil and
NGLs per day.

  Rocky Mountain Region

     Devon's operations in the Rocky Mountain region include properties in
Wyoming, Utah, and Northern New Mexico. These assets include conventional oil
and gas properties and coalbed methane projects. As of December 31, 2002, the
Rocky Mountain region comprised 11% of Devon's proved reserves.

     Devon began producing coalbed methane in the San Juan Basin of New Mexico
in the mid-1980s and began drilling coalbed methane wells in the Powder River
Basin of Wyoming in 1998. As of December 31, 2002, Devon has drilled over 1,500
coalbed methane wells in the Powder River Basin. Devon's net coalbed methane gas
production from the basin was approximately 80 MMcf per day as of December 31,
2002, and Devon plans to drill more than 100 wells in the Powder River Basin in
2003. Current production in the basin is primarily from the Wyodak coal
formation.

     The deeper Big George formation is currently being tested by Devon and
others with working interests in the area. Increased development in the Big
George is subject to an Environmental Impact Statement, which has been completed
and is expected to be approved within the next few months. Pending this approval
and the success of current pilot projects, the Big George could significantly
expand the coalbed methane play into the western portion of the Powder River
Basin. Devon's leasehold in this area would allow for the development of four
projects in the Big George.

     Devon is also continuing to develop conventional gas operations at the
Washakie field in Wyoming. Devon drilled 31 wells in 2002 and plans to drill
another 30 wells in 2003. Devon has interests in over 200,000 acres. Devon's
current net production from Washakie is approximately 77 MMcf and 1,100 Bbls of
oil and NGLs per day.

  GULF OF MEXICO AND GULF COAST

     Devon is active in the offshore Gulf of Mexico and onshore South Texas and
South Louisiana. Devon operates 100 structures in the Gulf of Mexico
predominantly in the outer shelf area offshore Louisiana.

                                        20


The Gulf of Mexico and Gulf Coast region represented 5% of Devon's proved
reserves at December 31, 2002.

     Devon is applying four-component, or 4-C, seismic technology to identify
prospects on large tracts of its shelf acreage. Traditional seismic techniques
have not been successful in imaging reservoirs lying below shallow gas
reservoirs and salt deposits, but 4-C seismic technology is allowing Devon's
geoscientists to more accurately picture these unexplored formations. Devon has
conducted two large 4-C seismic surveys offshore Louisiana and, in 2002, Devon
drilled four successful wells in the West Cameron area based on 4-C data. Devon
is also reprocessing large seismic data volumes using pre-stack depth migration
to prospect for oil and gas in the outer shelf. In addition, Devon is utilizing
new long cable 3-D seismic data to better image deep shelf prospects. Devon has
developed a significant inventory of drilling opportunities for deeper gas near
our infrastructure in offshore Louisiana and offshore Texas.

     In the deepwater Gulf of Mexico, Devon participated in its first subsalt
discovery in 1999 in the Enchilada Field located in Garden Banks 128. Since then
Devon has operated several successful subsea completions ranging from Garden
Banks to Viosca Knoll. Devon has experience with the successful installation and
operation of subsea production equipment, which is an important component of any
deepwater program. Devon's Pecten discovery in Viosca Knoll Block 694, a subsea
tieback completed in 2001, is currently producing approximately 17 MMcf of gas
per day.

     Because deepwater exploration requires significant capital expenditures,
Devon's strategy is to share projects with experienced partners to mitigate
risk. In 2002, Devon entered into a four-well joint venture with ChevronTexaco
that will earn Devon a 25% working interest in 71 deepwater blocks and 14
identified exploratory prospects. Devon also made a potentially significant
discovery in 2002 in 8,200 feet of water at Cascade located in Walker Ridge
Block 206 and plans to participate with other partners in four or five deepwater
wells in 2003, including a confirmation well at Cascade.

     Devon's operations in the Gulf Coast region include operations onshore in
South Texas, where exploration for oil and gas is accelerating. Devon's
activities in this area have focused on exploration in the Edwards, Wilcox and
Frio/Vicksburg formations. Devon also acquired additional production and
undeveloped acreage in the South Texas area from its acquisition of Mitchell.

  CANADA

     Devon's acquisition of Anderson in late 2001 significantly increased the
relative importance of Devon's Canadian operations. The Anderson acquisition
strengthened Devon's holdings in the Deep Basin located in Western Alberta and
Eastern British Columbia, and the Foothills Region of Northeastern British
Columbia. As of December 31, 2002, 36% of Devon's proved reserves were in
Canada.

     Devon had sought for years to obtain a significant acreage position in the
Deep Basin, but other operators, including Anderson, already controlled most of
the acreage. As a result of the Anderson acquisition, Devon now holds over
800,000 net acres in the Deep Basin. The profitability of Devon's operations in
the Deep Basin is enhanced by its ownership in nine gas processing plants in the
area. Devon plans to drill about 100 wells in the Deep Basin in 2003. These
reservoirs tend to be rich in liquids, producing up to 100 barrels of NGLs with
each MMcf of gas.

     Late in 2002, Devon commenced production from the first of several wells it
has drilled in the Grizzly Valley area of the Foothills Region of Northeastern
British Columbia. Due to gas pipeline and processing limitations, initial
production has been limited to 10 MMcf of gas per day. However, a pipeline
extension slated for completion in the second quarter of 2003 should allow
production to increase to about 35 MMcf per day.

     Devon acquired from Anderson approximately 1.5 million net acres in the
MacKenzie Delta region and the shallow waters of the Beaufort Sea in Northern
Canada. In 2002, a Devon well in the MacKenzie Delta encountered over 110 feet
of natural gas pay in the Kamik sand. Two to three more exploratory wells are
planned by Devon in the MacKenzie Delta in 2003.

                                        21


     Devon has been active for over a decade in Northeastern British Columbia,
an area in which Devon owns approximately 1.35 million net undeveloped acres of
land. In 2002, Devon participated in the drilling of 67 gross wells and plans to
participate in the drilling of approximately 93 wells in 2003.

     The Peace River Arch area is a more mature area with both light oil and
natural gas potential. Most of Devon's position in the Peace River Arch was
acquired through the Anderson acquisition. Devon holds roughly 730,000 net
undeveloped acres in the Peace River Arch, and the average production in 2002
was approximately 140 MMcf of natural gas and 7,500 Bbls of NGLs per day net. In
2003, Devon plans to participate in the drilling of 71 gross wells in the Peace
River Arch. Devon has an interest in a production and processing infrastructure
in the Peace River Arch, which enhances Devon's operations in the area.

     In the Northern Plains region of Northeastern Alberta, Devon has been
active for many years. While the area is a highly developed area with
winter-only access, Devon is very active, drilling in excess of 100 gross wells
per year. In 2002, average daily net production from the area was about 150 MMcf
of natural gas and approximately 3,400 Bbls of NGLs net. Natural gas is
encountered in multiple horizons at depths generally less than 1,300 feet. Devon
holds approximately 2 million net undeveloped acres in this area.

     Devon has about 400,000 net undeveloped acres in the central and southern
region of Alberta, and the average production from this area in 2002 was
approximately 80 MMcf of natural gas and 20,000 Bbls of NGLs per day net.
Planned activity in 2003 includes drilling approximately 70 gross wells that
vary from deep Devonian tests to shallow Cretaceous tests.

     Devon is also active in exploration for and production of "cold-flow" heavy
oil in the Lloydminster area of Alberta and Saskatchewan where oil is found in
multiple horizons generally at depths of 1,000 to 2,000 feet. In 2003, Devon
plans to drill 134 gross wells with primarily a development focus. Average daily
production from the area in 2002 was approximately 37 MMcf of natural gas and
13,750 Bbls of crude oil net.

     Devon is also active in the evaluation of thermal heavy oil in Alberta
through its 13% ownership interest in the Surmont project, operated by
ConocoPhillips, and is actively evaluating the development of a 100% working
interest heavy oil lease at Jackfish and an 83% working interest heavy oil
project at Dover. Each of these heavy oil projects target bitumen (heavy
tar-like oil) through the use of Steam Assisted Gravity Drainage whereby a pair
of horizontal wells are utilized. Steam is injected in one well and is used to
heat the bitumen to allow it to gravity drain to the other horizontal production
well.

  INTERNATIONAL

     Devon's international activities are currently focused in development
projects in Azerbaijan and China and deepwater exploration in the combined South
Atlantic Margin of Brazil and West Africa. In 2002, Devon divested all remaining
interests in Argentina, Indonesia and Egypt. As of December 31, 2002, 9% of
Devon's proved reserves were in countries outside North America.

     In Azerbaijan, Devon has a 5.6% carried working interest in the large
Azeri-Chirag-Gunashli, or ACG, oil development project. Devon estimates that the
ACG field contains over 4.6 billion barrels of gross proved oil reserves. The
development project commenced in 2002. The Baku-T'Bilisi-Ceyhan (BTC) pipeline
to export oil for this project has been approved by the governments of
Azerbaijan, Georgia and Turkey.

     In China, Devon is an acreage holder in the Pearl River Mouth Basin in the
South China Sea and has been successful in discovering two new fields. Devon is
currently developing the Devon operated Panyu development project and expects
oil production from two offshore platforms and into a floating production-
storage and offloading vessel to commence in late 2003. Gross capital
expenditures for the project are $340 million, with Devon owning a 24.5% working
interest. Peak production is expected to reach 58,000 Bbls of oil per day
(15,000 Bbls of oil per day net to Devon) in 2004.

                                        22


     Devon's international exploration efforts are strategically focused in the
combined South Atlantic deepwater region of West Africa and Brazil. Devon's
presence in West Africa began in 1992 with exploration efforts resulting in the
discoveries of the Tchatamba fields in the shallow waters offshore Gabon. In
this region, Devon has five blocks and holds over 3.2 million net acres. Devon
plans to drill deepwater exploratory wells in its West Africa portfolio in Ghana
and Gabon in 2003. In Brazil, Devon will be acquiring a 3-D survey in a
Devon-operated deepwater block in early 2003 in order to identify future
drilling opportunities.

OCEAN'S PROPERTIES

     Ocean's properties are located primarily in three operating areas: (1) the
continental shelf and deepwater areas of the Gulf of Mexico, (2) onshore areas
of North America, and (3) internationally in Equatorial Guinea, Angola, Nigeria,
Cote d'Ivoire, Egypt, the Russian Republic of Tatarstan, Brazil and Indonesia.

  GULF OF MEXICO

     Ocean's Gulf of Mexico properties are located in offshore waters along the
coasts of Texas and Louisiana. In 2002, Ocean's Gulf of Mexico operations had
average daily production of 51 MBoe, or approximately 33% of its production for
the year.

     The major focus in the Gulf of Mexico area is associated with deepwater
prospects where Ocean currently has interests in 860,000 net acres covering 361
blocks. Exploratory efforts are focused on specific regions followed by
subsequent development of neighboring discoveries with production from a large,
centrally located facility. Ocean's interests in the Gulf of Mexico include:

     - Nansen/Boomvang/Navajo Complex -- During 2002, production began from
       Ocean's first major deepwater fields in the East Breaks area of the Gulf
       of Mexico where Ocean made two significant discoveries in 1999. The
       Nansen and Boomvang production spars have a combined daily production
       capacity of up to 80,000 Bbls of oil and 400 MMcf of gas. Production
       began from the Nansen field (in which Ocean owns a 50% working interest)
       in January 2002 and from the Boomvang fields (in which Ocean owns a 20%
       working interest) in June 2002. Additional discoveries made in the West
       Navajo field (in which Ocean owns a 50% working interest) and the
       Northwest Navajo field (in which Ocean owns a 50% working interest)
       during 2002 are being linked to the nearby Nansen spar via subsea
       tiebacks. Ocean's combined net production from the Nansen/Boomvang/Navajo
       complex was approximately 37 MBoe per day at December 31, 2002.
       Completion of dry tree and subsea wells is expected to continue through
       the first half of 2003.

     - Zia Development -- The Zia project (in which Ocean owns a 65% working
       interest) in Mississippi Canyon is the first deepwater development
       project operated by Ocean, with production scheduled to begin in late
       summer 2003. The field will utilize a subsea completion that will flow
       approximately 16 miles to a platform in South Pass 89.

     - Magnolia Development -- Ocean is participating in the development of the
       Magnolia Field (in which Ocean owns a 25% working interest), located in
       Garden Banks in nearly 4,700 feet of water. Development drilling is
       currently underway, and platform construction has begun, with production
       anticipated to begin by year-end 2004.

     - Redhawk Development -- First production from the Redhawk natural gas
       discovery (in which Ocean owns a 50% working interest) in Garden Banks is
       anticipated in 2004. Fabrication of a cell spar for Redhawk has already
       commenced.

     - Atwater Valley Area -- Ocean participated in two discoveries in the
       Atwater Valley area, Merganser (in which Ocean owns a 50% working
       interest) and Vortex (in which Ocean has a 33% working interest). Ocean
       is continuing to evaluate its additional exploration opportunities in the
       area.

                                        23


     - Trident Prospect -- Ocean and Ocean's partners are currently evaluating
       the commerciality of the Trident discovery in Alaminos Canyon (in which
       Ocean owns a 13% working interest).

     In 2003, Ocean anticipates drilling another six prospects in the deepwater
Gulf of Mexico, including four prospects that will be Ocean-operated, Yorktown
(in which Ocean owns a 50% working interest) in Mississippi Canyon, Shiner (in
which Ocean owns a 25% working interest) in Garden Banks, Tuscany East (in which
Ocean owns a 37.5% working interest and Devon owns a 25% working interest) in
Desoto Canyon and Aztec (in which Ocean owns a 50% interest) in Keathley Canyon.
Ocean also intends to be active in the shelf area, specifically in the core
areas of the Delta and central Gulf of Mexico, where Ocean's activities in 2002
included a workover and recompletion program designed to maximize production
from the area and successful development drilling programs at the Main Pass 69
field (in which Ocean owns a 100% working interest) and the Eugene Island 126
field (in which Ocean owns a 100% working interest). The recompletion and
workover program will continue during 2003.

  NORTH AMERICA ONSHORE

     Ocean's portfolio of onshore properties in North America is focused
primarily in the Rocky Mountains, the Permian Basin, Anadarko, East Texas, North
Louisiana and the Gulf Coast onshore regions of South Texas and South Louisiana.
During 2002, Ocean's share of production from the North America Onshore area
averaged about 47 MBoe per day. Ocean's onshore interests in North America
include:

     - Rocky Mountains -- The Rocky Mountain area contains the Bear Paw field
       where Ocean has a large inventory of drilling locations. In 2002, Ocean
       completed a 75-well development drilling program in the Bear Paw Field,
       in which Ocean owns a 96% working interest. In 2003, Ocean intends to
       continue development of the field by expanding its drilling program to
       100 wells. Ocean also plans to implement 3-D seismic for the first time
       within the Bear Paw producing area to help identify optimum drilling
       locations within new fault blocks. Ocean obtained a 75% working interest
       in approximately 60,000 acres in Northwest Colorado during 2002 and plans
       to conduct exploratory activities on the acreage during 2003.

     - Permian Basin -- Ocean's 2002 activities in the Permian Basin included a
       successful horizontal drilling and development program in Ward County.
       The program included the drilling of two 17,000 foot horizontal gas
       wells, the Harding Fee #2H and the Harding Fee #3H (in which Ocean owns a
       65% working interest), which targeted the Montoya formation. In 2003,
       Ocean intends to continue horizontal drilling and development activities
       and plans to drill an exploratory horizontal well in Midland County.
       Ocean will also continue exploratory efforts in West Texas and New
       Mexico.

     - Anadarko -- Ocean continues to exploit its acreage position in the
       Anadarko area. During 2002, the primary focus was in the Strong City and
       Watonga-Chickasha areas in the Anadarko Basin and the Wilburton area in
       the Arkoma Basin. For 2003, Ocean plans additional development of the
       Anadarko area, particularly in the Texas Panhandle.

     - East Texas and North Louisiana -- Ocean's focus in this region is the
       Bossier, Carthage and Stockman Fields in East Texas and the Vernon Ansley
       and Ruston Field areas in North Louisiana where development drilling and
       recompletion activities are ongoing.

     - Gulf Coast -- Ocean's primary focus for 2002 in the onshore Gulf Coast
       region was in the Wilcox trend in South Texas. Exploitation activities
       are expected to continue in 2003, with increased development drilling, a
       continued active recompletion/workover program and the use of 3-D seismic
       to identify more exploration leads.

  INTERNATIONAL

     Ocean produces oil and gas in five countries outside of the United
States -- Equatorial Guinea, Egypt, Russia, Cote d'Ivoire and Indonesia. In
addition, Ocean has interests in other countries, including Angola, Brazil and
Nigeria. Ocean discontinued exploratory activities in Pakistan in 2002.

     Ocean's international operations include:

     - Equatorial Guinea -- Ocean has three production sharing contracts
       covering about 1.9 million gross acres in Equatorial Guinea, which
       included 20% of Ocean's reserves and accounted for approximately 22% of
       Ocean's production in 2002. In 2002, Ocean's share of production averaged
       about 33 MBoe per day. Nearly half of Ocean's international budget for
       2003 is slated to be spent in Equatorial Guinea on continued development
       of the Zafiro field. Ocean's interests in Equatorial Guinea include:

      - Block B (in which Ocean owns a 23.75% working interest) covers about
        547,000 gross acres and contains the Zafiro field, where production
        currently occurs from two facilities, the Zafiro Producer and the Jade
        Platform. In 2002, Ocean continued development of this area by
        successfully drilling eight development wells, one of which is the
        longest extended reach well from the Jade Platform to date, with
        approximately 13,000 feet of horizontal displacement. Ocean has also
        been conducting development activities in the Southern Expansion Area of
        the Zafiro field. To date, seven development wells have been drilled and
        suspended pending arrival of the Serpentina, a floating production,
        storage and offloading vessel that will add the capacity needed to begin
        producing from this area. This project remains on schedule to begin in
        the second half of 2003.

      - Ocean has been conducting exploratory activities on Block C (in which
        Ocean owns a 37.6% working interest). An exploratory well failed to
        discover commercial quantities of reserves, and Ocean is evaluating the
        remaining potential for oil in Block C. This block covers about 649,000
        gross acres.

      - In early 2002, Ocean entered into a production sharing contract with the
        government of Equatorial Guinea covering Corisco Bay Block N (in which
        Ocean owns a 25.5% working interest), an approximately 678,000 gross
        acre concession in the Rio Muni Basin offshore the mainland of
        Equatorial Guinea. Interpretation of final processed 3-D seismic data
        for Block N is underway, and Ocean expects to drill an exploratory well
        in the second half of 2003.

     - Egypt -- Egypt comprised about 4% of Ocean's reserves and accounted for
       about 6% of Ocean's production in 2002, and Ocean's share of production
       averaged about 9 MBoe per day. Ocean's Egyptian operations consist of
       working interests in seven concessions covering approximately 3.8 million
       gross acres. Four of these concessions are producing (East Zeit, Qarun,
       East Beni Suef and West Abu Gharadig). Ocean also holds an interest in
       three exploratory blocks, Southwest Gebel el Zeit in the Gulf of Suez,
       Ras Abu Darag in the Northern Gulf of Suez and North Zeit Bay in the Gulf
       of Suez.

     - Cote d'Ivoire -- Ocean is the operator on three blocks in Cote d'Ivoire,
       which cover about 313,000 gross acres. Ocean also owns and operates the
       Lion Gas Plant. Ocean's share of production in Cote d'Ivoire averaged 7
       MBoe per day in 2002.

     - Russia -- Ocean has a net 45% interest in a joint venture in the Russian
       Republic of Tatarstan. In 2002, the joint venture successfully drilled 29
       development wells and two exploratory wells in the Onbysk and Demkino
       fields and plans additional development activity in 2003. Ocean's share
       of production averaged about 5 MBoe per day in 2002.

     - Angola -- Ocean currently holds approximately 2.7 million gross offshore
       acres in the country. Ocean acquired an operated interest of about 1.2
       million gross acres in Block 10 (in which Ocean owns a 35% working
       interest) in early 2002 and is in the process of conducting 3-D seismic
       acquisition. Ocean plans to drill the first exploratory well on Block 10
       in 2003. In addition, Ocean

                                        25


       holds an interest in about 1.2 million gross acres in Block 24 (in which
       Ocean owns a 40% working interest). Ocean will become operator of the
       block following the drilling of the Varina North well. Ocean anticipates
       drilling a second exploratory well on Block 24 in late 2003.

     - Brazil -- Ocean holds interests in two deepwater blocks offshore Brazil.
       Ocean has a 65% working interest in Block BM-C-15, which it operates, and
       a 20% working interest in Block BM-S-22. The two blocks cover a total of
       about 1.2 million gross acres. Ocean is in the process of interpreting
       3-D seismic data on Block BM-C-15 in the Campos Basin and plans to drill
       on this block in late 2003 or early 2004.

     - Nigeria -- In early 2003, Ocean finalized a production sharing contract
       to become operator of OPL Block 256 (in which Ocean owns a 95% working
       interest). The 631,000 gross acre block is located in water depths of
       6,000 to 9,500 feet. The working program calls for seismic studies and
       the drilling of three obligatory exploration wells, the first of which is
       expected to begin in 2004. Ocean plans to farm out a portion of its
       interest in this block.

     - Indonesia  -- Ocean owns a 1.7% interest in a joint venture in East
       Kalimantan, Indonesia. The majority of the joint venture's revenue
       results from the sale of liquefied natural gas.

                                   THE MERGER

BACKGROUND OF THE MERGER

     Beginning in late October 2002, initial conversations between members of
Ocean's senior management and members of Devon's senior management were held
regarding the possibility of a business combination between Ocean and Devon. On
October 25, 2002, Ocean and Devon signed a confidentiality agreement. Shortly
thereafter, Devon and Ocean began exchanging confidential evaluation materials
and conducting due diligence investigations of each other.

     On October 30, 2002, the executive committee of Ocean's board of directors
met to discuss the possibility of a business combination between Ocean and Devon
and the status of ongoing discussions between Ocean and Devon. Representatives
of Ocean and Devon continued to hold discussions and conduct due diligence
relating to a potential business combination throughout November and early
December 2002.

     On November 13, 2002, J. Larry Nichols, Devon's Chairman, President and
Chief Executive Officer, met with James T. Hackett, Ocean's Chairman, President
and Chief Executive Officer, in Houston, Texas to discuss a potential business
combination between Ocean and Devon.

     On November 15, 2002, Ocean's board of directors held a special meeting to
discuss the potential business combination with Devon and to review financial
data and other information regarding Devon.

     On November 20 and 21, 2002, a meeting of members of the senior management
teams of Ocean and Devon, including Messrs. Nichols and Hackett, was held in
Galveston, Texas to review technical matters relating to the potential business
combination between Ocean and Devon.

     From late November 2002 through mid-December, Ocean's and Devon's legal
counsel conducted due diligence investigations, exchanged draft merger
agreements and related documents and held discussions and negotiations regarding
the terms of the merger agreement.

     On December 3, 2002, Devon's board of directors held a regularly scheduled
meeting in Oklahoma City at which the board of directors discussed the potential
merger with Ocean and reviewed information regarding Ocean.

     On December 10, 2002, Devon's board of directors held a special meeting to
discuss the potential merger with Ocean and to receive an update regarding the
status of the discussions between Ocean and Devon.

     On December 13, 2002, Ocean's board of directors held a regularly scheduled
meeting. At that meeting, Ocean's board of directors discussed the status of the
potential merger with Devon and received presentations from Ocean's management,
financial advisors and legal representatives. Mr. Nichols of Devon attended a
portion of that meeting to discuss the potential merger and to answer questions
from Ocean's directors.

     On December 14, 2002, Devon's board of directors held a special meeting to
discuss the potential merger with Ocean. Later on December 14, 2002, Ocean and
Devon decided to delay further discussions regarding a potential merger, pending
completion of additional due diligence, including exchange of year-end financial
and operating data.

     On January 29, 2003, Messrs. Nichols and Hackett met in Houston, Texas to
discuss the resumption of discussions about a potential merger between Ocean and
Devon. On February 3, 2003, Messrs. Nichols and Hackett agreed that Ocean and
Devon would resume discussions regarding a potential merger.

     On February 10 and 11, 2003, members of Devon's and Ocean's management
teams met in Houston, Texas, along with representatives from their respective
outside oil and gas engineering firms, to exchange technical data and discuss
various technical due diligence issues.

                                        35


     From mid-February through February 23, 2003, representatives of Ocean and
Devon finalized due diligence investigations and continued to hold discussions
and negotiate the terms of the merger agreement and related matters.

     On February 21, 2003, Ocean's board of directors held a special meeting to
discuss the proposed merger. Representatives of Ocean's management, financial
advisors and legal counsel made presentations at that meeting and discussed the
proposed merger with Ocean's board of directors.

     On February 22, 2003, Devon's board of directors held a special meeting to
discuss the proposed merger. Representatives of Devon's management, financial
advisors and legal counsel made presentations at that meeting and discussed the
proposed merger with Devon's board of directors.

     On February 23, 2003, Ocean's board of directors held a special meeting at
which it received the opinion of Deutsche Bank Securities Inc. to the effect
that, as of the date of such opinion, the 0.414 exchange ratio was fair to Ocean
common stockholders from a financial point of view. Thereafter, Ocean's board of
directors unanimously approved and adopted the merger agreement and resolved to
recommend that Ocean's stockholders vote to adopt the merger agreement. At that
time, Ocean's board of directors also approved an amendment to Ocean's
stockholder rights plan that had the effect of causing the stockholder rights
plan to be inapplicable to Devon and the merger.

     Also on February 23, 2003, Devon's board of directors held a special
meeting at which it received the opinion of Morgan Stanley & Co. Incorporated to
the effect that, as of the date of such opinion, the 0.414 exchange ratio
pursuant to the merger agreement was fair to Devon from a financial point of
view. Thereafter, Devon's board of directors unanimously approved and adopted
the merger agreement, approved the issuance of shares of Devon common stock
pursuant to the merger agreement and resolved to recommend that Devon's
stockholders approve the issuance of shares of Devon common stock pursuant to
the merger agreement.

     Following the Ocean board meeting and the Devon board meeting on February
23, 2003, Ocean and Devon executed the merger agreement.

     On February 24, 2003, Ocean and Devon publicly announced the execution of
the merger agreement.

     On February 27, 2003, a lawsuit was filed in the District Court of Harris
County, Texas, naming as defendants Ocean and all of the members of Ocean's
board of directors alleging that the exchange ratio in the merger is inadequate
and unfair to Ocean common stockholders and alleging the breach of the
defendants' fiduciary duties to Ocean stockholders. The complaint seeks class
action status. It also seeks injunctive relief against completing the merger or,
if the merger is completed, rescission of the merger, monetary damages in an
unspecified amount and recovery of the plaintiff's costs and attorneys' fees.

RECOMMENDATION OF OCEAN'S BOARD OF DIRECTORS AND REASONS FOR THE MERGER

     Ocean's board of directors has unanimously approved and adopted the merger
agreement and determined that it is advisable and in the best interests of Ocean
and its stockholders. Accordingly, the board recommends that Ocean stockholders
vote to adopt the merger agreement.

     Ocean's board of directors consulted with Ocean's management, as well as
its financial and legal advisors, and considered various factors, including the
following, in unanimously approving the merger agreement and the merger (the
order does not reflect the relative significance):

     - Complementary Assets and Diversification.  Ocean believes that the
       combination of Ocean's and Devon's core operating assets will result in a
       more balanced, diversified oil and gas company. Ocean's oil and gas
       operations are concentrated in the deepwater Gulf of Mexico and
       internationally, and Ocean's onshore and shelf assets will be
       complementary to Devon's core natural gas operations in North America.
       Ocean believes that Devon's strong North American presence will provide
       Ocean stockholders with a more stable, diversified exploration and
       exploitation portfolio, reducing the risk associated with Ocean's higher
       impact exploration projects in the deepwater Gulf of Mexico and
       international locations. Based on production information for the fourth
       quarter of

                                        36


       2002 and on a pro forma basis, 90% of the combined company's worldwide
       production will be from North America with a production mix consisting of
       approximately 63% natural gas and 37% oil and NGLs.

     - Strong Pro Forma Financial Profile; Synergies.  Because of Devon's size
       and significant, stable North American natural gas position, Ocean
       believes that the combined company's pro forma financial profile will
       consist of an improved balance sheet and credit ratings compared to Ocean
       on a stand-alone basis, which Ocean believes will result in improved
       access to capital at a lower overall cost. Ocean believes that the
       financial profile of the combined company will be enhanced following the
       merger as a result of cost savings of at least $50 million annually.

     - Acceleration of Exploration Program and Long-Term Growth.  Ocean believes
       that the combined company's substantial scale and cash flows will permit
       a greater allocation of resources to Ocean's deepwater Gulf of Mexico and
       international exploration inventory. The ability of Ocean stockholders to
       access Devon's capital resources to accelerate Ocean's prospect inventory
       is expected to provide Ocean stockholders with greater long-term value
       than Ocean could achieve independent of Devon.

     - Reduction of Execution Risk.  Ocean believes that the overall size of the
       combined company will reduce the execution risk associated with
       development of large-scale deepwater development projects. The
       combination of Devon's size and stable operating assets with Ocean's
       high-potential growth prospects is expected to result in better
       comparative valuations over time for Ocean's stockholders than Ocean
       could achieve on a stand-alone basis.

     - Scope and Scale of the Combined Company.  Devon and Ocean together
       produced approximately 2.4 Bcf of natural gas per day and 245,000 Bbls of
       oil and NGLs per day during the fourth quarter of 2002. The combined
       company is expected to have daily production of about 650 MBoe, estimated
       proved reserves of 2.2 billion Boe (84% of which are in North America)
       and approximately 29 million net undeveloped acres. Ocean believes that
       the scope and scale of the combined company will result in greater
       marketing, purchasing and operating strength, facilitate internal growth
       and promote long-term stockholder value.

     - Per Share Accretion.  Ocean expects that the merger will provide
       immediate accretion to Ocean stockholders in cash flows per share.

     - Merger Consideration.  The value of the merger consideration as of
       February 21, 2003 -- the last trading day prior to announcement of the
       execution of the merger agreement -- represented an approximate 4%
       premium over the closing price of Ocean's common stock on that date. The
       merger agreement requires Devon to issue approximately 73.4 million
       shares of its common stock to Ocean stockholders, which would result in
       Ocean stockholders owning approximately 32% of the combined company's
       outstanding voting shares based on the number of shares of Ocean common
       stock and Devon common stock outstanding on the date on which the merger
       agreement was signed. Ocean stockholders will have the opportunity to
       participate in any post-merger appreciation in the value of Devon common
       stock. This 32% equity percentage matches or exceeds Ocean's
       contributions to the combined company on several important 2002 measures:
       earnings, cash flow, production, proved reserves and enterprise values.

     - Increased Liquidity.  The combined company's common stock will be traded
       on the American Stock Exchange in substantially greater dollar volumes
       than that of Ocean on the New York Stock Exchange, providing greater
       liquidity for Ocean stockholders and for new institutional investors.

     - Tax Consequences of the Merger.  The merger is structured to be tax-free
       for U.S. federal income tax purposes to Ocean common stockholders to the
       extent that they receive Devon common stock in exchange for their shares
       of Ocean common stock.

     - Opinion of Financial Advisors.  Ocean's board of directors also
       considered the presentation and opinion of Deutsche Bank described
       elsewhere in this document to the effect that, based on the

                                        37


       assumptions and other matters stated in its opinion, the 0.414 exchange
       ratio was fair from a financial point of view to Ocean common
       stockholders as of the date of the merger agreement.

     Ocean recognized that there are risks associated with the merger and an
investment in the combined company, including the following risks:

     Integration Risks.  The combined company will face risks typical to major
business combinations, including challenges associated with integrating
personnel, operations, financial reporting and information technologies.
Unintended and unforeseen consequences could develop in the process of that
integration, and the combined company may lose key employees, customers or
suppliers as a result.

     Limited Premium and Fixed Exchange Ratio.  Ocean considered the limited
premium -- approximately 4% over the closing price of Ocean's common stock as of
February 21, 2003 -- in making its recommendation in favor of approval and
adoption of the merger agreement. Moreover, because the merger agreement
contains a fixed exchange ratio, the market value of the consideration to be
received by Ocean stockholders at the effective time of the merger will depend
on the trading price of Devon common stock at the effective time of the merger.

     Increased Indebtedness.  Following the merger, the combined company is
expected to have in excess of $9 billion in total debt and a higher total debt
to capitalization ratio than Ocean had on a stand-alone basis. This increased
indebtedness could limit the combined company's flexibility as a result of debt
service requirements and restrictive covenants and may limit the combined
company's business strategy or its ability to access additional capital.

     Concentration of Exposure.  Devon's estimated proved reserves were 60%
natural gas at December 31, 2002, with the majority of its reserves located in
North America. Devon's operating results are more dependent on gas prices and
the North American market than Ocean's operating results, and adverse
developments with respect to either could negatively impact the combined
company's operating results.

     Execution.  The merger might not be completed as a result of a failure to
satisfy the conditions contained in the merger agreement or other reasons.
Neither Ocean nor Devon is obligated to complete the merger unless the
conditions in the merger agreement are satisfied or, in some cases, waived.

     The preceding discussion of the information and factors considered and
given weight by Ocean's board of directors is not intended to be exhaustive.
However, Ocean believes that the discussion includes all of the material factors
that it considered. In reaching its decision to approve and to recommend
approval to Ocean stockholders of the merger agreement, Ocean's board of
directors did not assign any relative or specific weights to the factors it
considered. Individual directors may have given different weights to different
factors.

RECOMMENDATION OF DEVON'S BOARD OF DIRECTORS AND REASONS FOR THE MERGER

     Devon's board of directors has unanimously approved and adopted the merger
agreement and determined that it is advisable and in the best interests of Devon
and its stockholders. Accordingly, the board recommends that Devon stockholders
vote to approve the issuance of Devon common stock pursuant to the merger
agreement.

     The merger is part of Devon's overall business strategy for growth through
exploration and development of existing properties and through strategic mergers
and acquisitions. In reaching its decision to approve and adopt the merger
agreement, Devon's board of directors consulted with Devon's management, as well
as its financial and legal advisors. Devon's board of directors believes that
Devon and its stockholders will benefit from the merger for the following
reasons (the order does not reflect the relative significance):

     - Combination of Ocean's Prospects with Devon's Capital Resources.  Ocean
       has significant development projects and exploration prospects. By
       combining Devon's excess operating cash flow (estimated to be between
       $500 million and $700 million in fiscal 2003) with Ocean's project

                                        38


       inventory, Devon expects to enhance Ocean's ability to develop and
       exploit its prospects while creating a more diverse company.

     - Complementary, Focused Asset Base.  Approximately 90% of Ocean's
       operations are within Devon's current core areas of the shelf and
       deepwater areas of the Gulf of Mexico, West Africa, the Rocky Mountains,
       the Permian Basin, East Texas and the Gulf Coast. This is expected to
       facilitate the integration of Devon's and Ocean's businesses and the
       realization of anticipated synergies and economies of scale.

     - Deleveraging Impact.  The merger improves a number of Devon's financial
       measures commonly used to assess a company's credit rating, including
       Devon's ratios of (1) total debt to capitalization, (2) debt to cash
       flow, (3) earnings before interest, taxes, depreciation and amortization
       to interest, and (4) debt per proved Boe reserves.

     - At-the-Market Exchange Ratio.  The 0.414 exchange ratio was intended to
       reflect the relative market prices of Devon's and Ocean's common stock
       for about 30 days prior to the date of the merger agreement. This
       reflects the fact that the merger is a strategic merger in which Ocean's
       stockholders will receive Devon common stock in the merger representing
       about 32% of the combined company's outstanding voting shares based on
       the number of shares of Ocean common stock and Devon common stock
       outstanding on the date on which the merger agreement was signed. Devon's
       board of directors believes the "at-the-market" exchange ratio is fair to
       Devon and its stockholders.

     - Increased Presence in the Gulf of Mexico and West Africa.  The merger
       significantly enhances Devon's position in the Gulf of Mexico and West
       Africa. Ocean's Gulf of Mexico division is more than twice as large as
       Devon's existing Gulf of Mexico operations, as measured by proved
       reserves as of December 31, 2002. Ocean has a significant West African
       presence to complement Devon's existing West African position. Ocean also
       has substantial production from the Zafiro field in offshore Equatorial
       Guinea.

     - Identifiable Near-Term Production Growth.  In 2002, Ocean began
       production from its major deepwater discoveries in the Nansen and
       Boomvang fields in the Gulf of Mexico. Ocean has other material deepwater
       Gulf of Mexico discoveries/development projects that are scheduled to
       commence production in 2003 and 2004. Most of these are in water depths
       that are less than 5,000 feet, which means that they can be operated
       using existing technology and tied into existing infrastructure.
       Production from Ocean's non-operating interest in the Zafiro field in
       Equatorial Guinea is currently increasing. Devon's board of directors
       believes that these deepwater projects provide Ocean with near-term
       production growth. Devon estimates that the combined company's production
       growth profile will be between 4% and 6% per annum over the next two to
       three years.

     - Enhanced Portfolio of Impact Projects/Large Inventory of Identified
       Prospects.  Ocean holds a deepwater exploratory position in the Gulf of
       Mexico and the South Atlantic Margin. In the Gulf of Mexico, Ocean holds
       approximately 1.1 million net acres covering about 360 blocks, with over
       50 identified prospects and leads. In the South Atlantic Margin, Ocean
       has exposure in blocks in offshore Equatorial Guinea, Brazil and Nigeria
       that Devon believes hold exploration potential. Devon believes that the
       combination of Devon and Ocean provides a compelling blend of stable,
       growing production, lower risk development drilling/exploitation
       opportunities and significant potential growth exploration exposure.

     - Deepwater Expertise.  Devon expects to benefit from sharing deepwater
       technology and expertise with Ocean.

     - Synergies.  Devon expects that the merger will create annual cost savings
       of at least $50 million.

                                        39


     - Larger Size.  The combined company will be significantly larger than
       Devon is now and, as a result of the larger size:

      - Devon is expected to have greater liquidity in the market for its
        shares;

      - Devon should be able to consider future transactions that would not
        otherwise be possible; and

      - Devon should have greater marketing, purchasing and operating strengths.

     - Opinion of Financial Advisor.  Devon's board of directors also considered
       the presentation and opinion of Morgan Stanley & Co. Incorporated
       described elsewhere in this document to the effect that, based on the
       assumptions and other matters stated in its opinion, the 0.414 exchange
       ratio pursuant to the merger agreement was fair from a financial point of
       view to Devon as of the date of the opinion.

     Devon recognized that there are risks associated with the merger and the
merger agreement, including the following risks:

     - Integration Risks.  The operations, technologies and personnel of the two
       companies may not be successfully integrated. The merger will include
       risks commonly associated with similar transactions, including
       unanticipated liabilities, unanticipated costs and diversion of
       management's attention. The combined company may also experience
       operational interruptions or the loss of key employees, customers or
       suppliers.

     - Dilution.  The merger is expected to be slightly dilutive in the near
       term to Devon's earnings per share, cash flow per share, production per
       share and reserves per share on a pro forma basis, depending on various
       assumptions, including future commodity price levels.

     - Capital Needs of Combined Company.  The capital outlays necessary to
       satisfy Ocean's existing commitments and to achieve the estimated growth
       in Ocean's business will be significant. In addition, the combined
       company will have significant debt maturities over the next several
       years. There can be no assurance that the combined company will be able
       to fund all of its capital needs from operating cash flows. The combined
       company may need to access the capital markets or sell assets to meet its
       capital needs in the future, and there can be no assurance that it will
       be able to do so on favorable terms or at all.

     - Larger Component of Proved Undeveloped Reserves.  The merger would
       increase Devon's PUDs from about 27% to 31% of its total reserves. PUDs
       involve greater uncertainty and require significant capital to develop.

     - International Projects.  The merger will increase Devon's exposure to
       investments outside of North America that may involve a higher degree of
       exposure to risks associated with political and economic instabilities.
       In addition, Ocean has made commitments in connection with being granted
       concessions by foreign countries that will be costly to fund and may
       limit the combined company's flexibility as to whether to continue
       operations in those countries.

     - Concentration of Exposure.  Ocean is dependent on several high volume
       assets, including the Zafiro field in Equatorial Guinea and the Nansen
       and Boomvang fields in the Gulf of Mexico, which are currently producing,
       and the Redhawk and Magnolia deepwater projects in the Gulf of Mexico,
       which are expected to come "on stream" in the near future. Should these
       assets not perform as well as expected, the combined company may not be
       able to achieve the desired growth, and the combined company could be
       required to write-down reserves.

     - Closing Conditions May Not Be Satisfied.  The merger might not be
       completed as a result of a failure to satisfy the conditions contained in
       the merger agreement or other reasons. Neither Devon nor Ocean is
       obligated to complete the merger unless the conditions in the merger
       agreement are satisfied or, in some cases, waived.

                                        40


     The preceding discussion of the information and factors considered and
given weight by Devon's board of directors is not intended to be exhaustive.
However, Devon believes that the discussion includes all of the material factors
that it considered. In reaching its decision to approve the merger agreement and
to recommend approval to Devon stockholders of the issuance of Devon common
stock in the merger, Devon's board of directors did not assign any relative or
specific weights to the factors it considered. Individual directors may have
given different weights to different factors.

  OPINION OF DEUTSCHE BANK SECURITIES INC. -- FINANCIAL ADVISOR TO OCEAN

     At the February 23, 2003 meeting of Ocean's board of directors, Deutsche
Bank rendered its oral opinion to Ocean's board of directors, subsequently
confirmed in writing, that as of February 23, 2003, and subject to and based on
the considerations in its opinion, the 0.414 exchange ratio was fair from a
financial point of view to Ocean common stockholders.

     The full text of Deutsche Bank's opinion, dated February 23, 2003, which
sets forth, among other things, the assumptions made and matters considered by
Deutsche Bank, is attached as Annex B to this document and is incorporated into
this document by reference. We urge you to read this opinion carefully and in
its entirety. Deutsche Bank's opinion is directed to Ocean's board of directors,
addresses only the fairness from a financial point of view of the 0.414 exchange
ratio to Ocean common stockholders, and does not address any other aspect of the
merger or constitute a recommendation to any Ocean stockholder as to how to vote
at the Ocean meeting. This summary is qualified in its entirety by reference to
the full text of the Deutsche Bank opinion.

     In connection with rendering its opinion, Deutsche Bank, among other
things:

     - reviewed certain publicly available financial statements and other
       business and financial information of Ocean and Devon, respectively;

     - reviewed certain internal financial statements and other financial and
       operating data concerning Ocean and Devon prepared by the respective
       managements of Ocean and Devon;

     - reviewed certain financial forecasts prepared by the respective
       managements of Ocean and Devon;

     - discussed with senior executives of Ocean and Devon certain strategic,
       financial and operational benefits they expect to derive from the merger;

     - discussed the past and current operations and financial condition and the
       prospects of Ocean and Devon with senior executives of Ocean and Devon;

     - reviewed the pro forma impact of the merger on, among other things,
       Ocean's and Devon's earnings per share, cash flow, consolidated
       capitalization and financial ratios;

     - reviewed information prepared by the members of the respective senior
       managements of Ocean and Devon relating to the relative contributions of
       Ocean and Devon to the combined company;

     - reviewed the reported prices and trading activity for Ocean common stock
       and Devon common stock;

     - compared the prices and trading activity of Ocean common stock and Devon
       common stock with similar information for the securities of certain other
       publicly traded companies;

     - reviewed the financial terms, to the extent publicly available, of
       certain business combination transactions that it deemed comparable in
       whole or in part;

     - participated in certain discussions and negotiations among
       representatives of Ocean and Devon and their financial and legal
       advisors;

                                        41


     - reviewed the merger agreement and certain related documents; and

     - performed such other analyses and considered such other factors as it
       deemed appropriate.

     Deutsche Bank relied upon, without independent verification, the accuracy
and completeness of the information supplied or otherwise made available to it
and assumed such accuracy and completeness for purposes of rendering its
opinion. With respect to the financial forecasts that Deutsche Bank received
from the respective managements of Ocean and Devon, as well as information
relating to certain cost savings, operating efficiencies, revenue effects and
financial synergies expected by Ocean and Devon to be achieved as a result of
the merger, Deutsche Bank assumed that the information provided was reasonably
prepared on bases reflecting the best currently available estimates and
judgments of the management of Ocean or Devon, as the case may be. Deutsche Bank
did not make any independent valuation or appraisal of the assets or liabilities
of Ocean or Devon, nor was Deutsche Bank furnished with any such appraisals.

     Deutsche Bank assumed that the representations and warranties contained in
the merger agreement are true and correct, that the parties to the merger
agreement will perform all of their covenants and agreements under the merger
agreement, and that all conditions to the parties' obligations to complete the
merger will be satisfied without any waiver. Deutsche Bank also assumed that all
material approvals and consents required in connection with the merger will be
obtained and that, in connection with obtaining any such approvals and consents,
or any amendments, modifications or waivers to any agreements, instruments or
orders to which Ocean or Devon is a party or is subject or by which it is bound,
no limitations, restrictions or conditions will be imposed or amendments,
modifications or waivers made that would have a material adverse effect on Ocean
or Devon or materially reduce the contemplated benefits of the merger. In
addition, Ocean informed Deutsche Bank, and for purposes of rendering its
opinion Deutsche Bank assumed, that the merger will be tax-free to each of Ocean
and Devon and their respective common stockholders. In arriving at its opinion,
Deutsche Bank analyzed the merger as a strategic business combination not
involving a sale of control of Ocean. Deutsche Bank was not authorized by Ocean
or its board of directors to solicit, and did not solicit, third-party
indications of interest with respect to the acquisition of all or any part of
Ocean or any other extraordinary transaction involving Ocean.

     The opinion of Deutsche Bank is necessarily based on financial, economic,
market and other conditions as in effect on, the information made available to
Deutsche Bank as of, and the financial condition of Ocean and Devon on, February
23, 2003.

  DEUTSCHE BANK'S FINANCIAL ANALYSIS

     The following is a summary of the material financial analyses performed by
Deutsche Bank in connection with rendering its opinion. These summaries of
financial analyses include information presented in tabular format. In order to
understand fully the financial analyses used by Deutsche Bank, the tables must
be read together with the text of each summary. The tables alone do not
constitute a complete description of the financial analyses.

     Historical Exchange Ratio Analysis.  Deutsche Bank compared the daily
closing share price of Ocean common stock to the daily closing price of Devon
common stock during the period beginning February 21, 2001 and ending February
19, 2003, and reviewed and analyzed the historical exchange ratios implied by
these comparisons.

                                        42


     Deutsche Bank also reviewed and analyzed the average of these historical
daily exchange ratios over various periods beginning February 21, 2001 and
ending February 19, 2003. The following table presents the implied exchange
ratios during the periods covered and as of February 19, 2003.

---------------

(1) Averages of exchange ratios based on daily closing prices.

     As the 0.414 exchange ratio was implied from the last month average of
Ocean and Devon common stock as of February 21, 2003, and Deutsche Bank, for
purposes of its opinion, reviewed Ocean's and Devon's stock prices until
February 19, 2003, Deutsche Bank also analyzed the implied exchange ratio on
February 21, 2003 by examining independently both Ocean's and Devon's stock
price movements for February 20 and 21, 2003. Based on the actual closing prices
per share of Ocean common stock and Devon common stock on February 20 and
February 21, 2003, the 0.414 exchange ratio is substantially the same as the
last month average implied by the February 19 closing prices.

     Last Twelve Months Trading Analysis.  Deutsche Bank reviewed the daily
closing share prices of Ocean common stock and Devon common stock over the
twelve months ended February 19, 2003. The table below shows the twelve-month
high and low closing prices during that period, compared with a closing price on
February 19, 2003 of $18.60 per share for Ocean common stock and $46.70 per
share for Devon common stock:

Ocean.......................................................  $22.62    $16.68
Devon.......................................................   52.76     35.54


     The range of exchange ratios implied by this range of values for Ocean
common stock and Devon common stock is between 0.316x and 0.636x. The foregoing
analysis was unaffected by the price movements in Ocean common stock and Devon
common stock on February 20 and February 21, 2003.

     Research Analysts' Future Price Targets Analysis.  Deutsche Bank reviewed
the 12-month price targets for Ocean common stock and Devon common stock as
projected in recent reports by analysts from six financial institutions, in the
case of Ocean, and seven financial institutions, in the case of Devon. Such
reports represent substantially all the research analysts' reports on Ocean and
Devon that were reasonably available and current at the time the analyses were
performed. One of the selected research analysts was an employee of Deutsche
Bank. These targets reflected each analyst's estimate of the future public
market trading price of Ocean common stock and Devon common stock at the end of
the particular period considered for each estimate. Deutsche Bank then arrived
at the present value for these targets using an estimated equity discount rate
of 10.0%.

     The range of exchange ratios implied by this range of values for Ocean
common stock and Devon common stock is 0.344x to 0.531x.

     Comparable Companies Analysis.  Deutsche Bank compared total enterprise
value (calculated as equity value adjusted for capital structure) to estimated
earnings before interest, taxes, depreciation and amortization, which is
referred to as EBITDAX, for Ocean and Devon for the fiscal years 2003 and 2004
and based on First Call estimates. (First Call Corporation compiles summaries of
financial forecasts published by various investment banking firms. We refer to
the information published by First Call Corporation as "First Call estimates.")
Deutsche Bank then compared the EBITDAX multiples obtained for Ocean and Devon
with multiples obtained for groups of selected oil and gas companies.

     The selected oil and gas companies forming the group to which Ocean was
compared were Anadarko Petroleum, Apache Corporation, Burlington Resources,
Encana Corporation, EOG Resources, Kerr-McGee Corporation, Murphy Oil, Noble
Energy, Pioneer Natural Resources and Unocal Corporation. We refer to those
companies as the "Ocean Selected Companies." The selected oil and gas companies
forming the group to which Devon was compared were: Anadarko Petroleum, Apache
Corporation, Burlington Resources, Encana Corporation, EOG Resources, Inc.,
Noble Energy, Unocal Corporation and XTO Energy. We refer to those companies as
the "Devon Selected Companies." Deutsche Bank selected these companies because
they are publicly traded companies with oil and gas operations that for purposes
of this analysis may be considered similar to those of Ocean and Devon.

     The analysis showed the following multiples:



                                                                 TOTAL

     Deutsche Bank then applied comparable company multiples (ranging between
4.6x and 5.8x for 2003 Total Enterprise Value/EBITDAX and between 4.8x and 5.9x
for 2004 Total Enterprise Value/ EBITDAX) to the corresponding Ocean statistics
based on publicly available estimates. Deutsche Bank then applied comparable
company multiples (ranging between 5.2x and 5.7x for 2003 Total Enterprise
Value/EBITDAX and between 5.6x and 6.2x for 2004 Total Enterprise Value/EBITDAX)
to the corresponding Devon statistics based on publicly available estimates. The
following table presents the range of exchange ratios implied by the resulting
mean valuation range based on implied Ocean and Devon share prices derived from
the 2003 and 2004 Total Enterprise Value as computed by Deutsche Bank.

based on First Call estimates. Deutsche Bank then compared these multiples with
multiples obtained for the Ocean Selected Companies and the Devon Selected
Companies.

     Pro Forma Contribution Analysis.  Deutsche Bank compared the pro forma
contributions of each of Ocean and Devon, based on First Call estimates, to the
combined company. Deutsche Bank reviewed pro forma estimates of earnings, cash
flow and EBITDAX for the years 2003 and 2004.

     Deutsche Bank also reviewed the contributions of the pre-transaction
enterprise value, the pre-transaction equity value, and proved reserves based on
2002 reported figures. As more fully described in the table below, Ocean and
Devon will contribute to the combined company in a manner consistent with the
participation that Ocean stockholders and Devon stockholders will have in the
ownership of Devon, as such participation is implied by the agreed 0.414
exchange ratio:

     Pro Forma Earnings, Cash Flow and Credit Impact Analysis.  Deutsche Bank
analyzed the pro forma effects of the merger and computed the resulting
accretion/dilution to the combined company's projected per-share earnings and
cash flow during 2003 and 2004, based on the agreed-upon exchange ratio.
Deutsche Bank also computed the resulting credit statistics for the combined
company based on the agreed-upon exchange ratio, including total debt to book
capitalization, estimated 2003 cash flow to total debt, estimated 2003 earnings
before interest and taxes (EBIT) to interest expense and total debt to
barrel-of-energy equivalent proved reserves. These computations used earnings
and cash flow projections for Ocean and Devon based on First Call estimates,
preliminary synergy estimates provided by Ocean's and Devon's management prior
to finalization of their synergy review, and certain purchase accounting
adjustments.

     The analysis indicated that, based on First Call estimates, the merger
would be accretive to estimated earnings per share in 2003 and 2004 of Ocean and
dilutive to estimated earnings per share in 2003 and 2004 of Devon, in each case
as compared to the same estimates for Ocean and Devon on a stand-alone basis.
Based on First Call estimates, the merger would also be accretive to cash flow
per share for Ocean and Devon in 2003 and 2004, in each case as compared to the
same estimates for Ocean and Devon on a stand-alone basis. In addition, the
analysis indicated that, based on First Call estimates, the merger should have a
positive impact on the credit statistics of the combined company as compared to
Devon on a stand-alone basis. Deutsche Bank also noted that Devon's senior
unsecured credit ratings, as published by Moody's Investors Service and Standard
and Poor's, on a stand-alone basis of Baa2/BBB were superior to Ocean's senior
unsecured credit ratings of Baa3/BBB-.

     Precedent Transactions Analysis.  Deutsche Bank examined fourteen selected
precedent business combination transactions which, for the purposes of its
analysis, it deemed to be comparable to the merger in whole or in part. Deutsche
Bank calculated the premium to unaffected share price and the enterprise value
per barrel-of-energy equivalent proved reserves that the targets in these
selected precedent transactions received and then calculated the median value
premium and value of proved reserves of the fourteen transactions. The
calculated median value premium to unaffected share price for the fourteen
transactions was 7.2% and the calculated median value of total enterprise value
to proved reserves was $7.34 per barrel-of-energy equivalent proved reserves.
The values implied to Ocean based on the 0.414 exchange ratio were a 3.9%
premium to unaffected share price and $8.21 per barrel-of-energy equivalent
proved reserves.

                                        46


     The precedent transactions examined were:

     - Burlington Resources/Louisiana Land & Exploration;

     - Ocean Energy/United Meridian Resources;

     - Kerr-McGee/Oryx Energy;

     - Ocean Energy/Seagull Energy;

     - Santa Fe Energy/Snyder Oil;

     - Devon Energy/PennzEnergy;

     - Burlington Resources/Poco Petroleums;

     - Anadarko Petroleum/Union Pacific Resources;

     - Devon Energy/Santa Fe Snyder;

     - Forest Oil/Forcenergy;

     - Stone Energy/Basin Exploration;

     - Westport Resources/Belco Oil and Gas;

     - Phillips Petroleum/Conoco Inc.; and

     - PanCanadian Energy/Alberta Energy.

     In connection with the review of the merger by Ocean's board of directors,
Deutsche Bank performed a variety of financial and comparative analyses for
purposes of rendering its opinion. The preparation of a fairness opinion is a
complex process and is not necessarily susceptible to partial analysis or
summary description. In arriving at its opinion, Deutsche Bank considered the
results of all of its analyses as a whole and did not attribute any particular
weight to any analysis or factor considered by it. Furthermore, Deutsche Bank
believes that the summary provided and the analyses described above must be
considered as a whole and that selecting any portion of its analyses, without
considering all of them, would create an incomplete view of the process
underlying its analyses and opinion. In addition, Deutsche Bank may have given
various analyses and factors more or less weight than other analyses and factors
and may have deemed various assumptions more or less probable than other
assumptions, so that the ranges of valuations resulting from any particular
analysis described above should not be taken to be Deutsche Bank's view of the
actual value of Ocean or Devon.

     In performing its analyses, Deutsche Bank made numerous assumptions with
respect to industry performance, general business and economic condition and
other matters, many of which are beyond the control of Ocean or Devon. Any
estimates contained in Deutsche Bank's analyses are not necessarily indicative
of future results or actual values, which may be significantly more or less
favorable than those suggested by such estimates. The analyses performed were
prepared solely as part of Deutsche Bank's analysis of the fairness from a
financial point of view to Ocean common stockholders of the 0.414 exchange ratio
and were prepared in connection with the delivery by Deutsche Bank of its
opinion, dated February 23, 2003, to Ocean's board of directors. The analyses do
not purport to be appraisals or to reflect the prices at which Ocean common
stock or Devon common stock might actually trade. The 0.414 exchange ratio and
other terms of the merger agreement were determined through arm's length
negotiations between Ocean and Devon and were unanimously approved by Ocean's
and Devon's boards of directors. Deutsche Bank did not recommend any specific
exchange ratio or form of consideration to Ocean or that any specific exchange
ratio or form of consideration constituted the only appropriate consideration
for the merger.

     Pursuant to the engagement letter between Ocean and Deutsche Bank, Ocean
agreed to pay Deutsche Bank a $5 million fee for services rendered by Deutsche
Bank in connection with the merger, including Deutsche Bank's delivery of an
opinion as to the fairness from a financial point of view of the 0.414

                                        47


exchange ratio to Ocean common stockholders as of the date on which the merger
agreement was signed. Ocean has also agreed to reimburse Deutsche Bank for its
expenses incurred in performing its services. In addition, Ocean has agreed to
indemnify Deutsche Bank and its affiliates, their respective directors,
officers, agents and employees and each person, if any, controlling Deutsche
Bank or any of its affiliates against certain liabilities and expenses,
including certain liabilities under the federal securities laws, related to or
arising out of Deutsche Bank's engagement and any related transactions.

     Deutsche Bank's opinion was one of the many factors taken into
consideration by Ocean's board of directors in making its unanimous
determination to approve the merger agreement. Deutsche Bank's analyses
summarized above should not be viewed as determinative of the opinion of Ocean's
board of directors with respect to the value of Ocean or Devon or of whether
Ocean's board of directors would have been willing to agree to a different
exchange ratio or form of consideration.

  OPINION OF MORGAN STANLEY & CO. INCORPORATED -- FINANCIAL ADVISOR TO DEVON

     At the February 23, 2003 meeting of Devon's board of directors, Morgan
Stanley rendered its oral opinion to Devon's board of directors, subsequently
confirmed in writing, that as of February 23, 2003, and subject to and based on
the considerations in its opinion, the 0.414 exchange ratio pursuant to the
merger agreement was fair from a financial point of view to Devon.

     The full text of Morgan Stanley's opinion, dated February 23, 2003, which
sets forth, among other things, the assumptions made, procedures followed,
matters considered and limitations on the scope of the review undertaken by
Morgan Stanley in rendering its opinion, is attached as Annex C to this document
and is incorporated into this document by reference. We urge you to read this
opinion carefully and in its entirety. Morgan Stanley's opinion is directed to
Devon's board of directors, addresses only the fairness from a financial point
of view of the 0.414 exchange ratio pursuant to the merger agreement to Devon,
and does not address any other aspect of the merger or constitute a
recommendation to any Devon stockholder as to how to vote at the Devon meeting.
This summary is qualified in its entirety by reference to the full text of the
Morgan Stanley opinion.

     In connection with rendering its opinion, Morgan Stanley, among other
things:

     - reviewed certain publicly available financial statements and other
       information of Ocean and Devon, respectively;

     - reviewed certain internal financial statements and other financial and
       operating data, including internal oil and gas reserve estimates,
       concerning Ocean and Devon prepared by the managements of Ocean and
       Devon, respectively;

     - reviewed certain financial forecasts prepared by the managements of Ocean
       and Devon, respectively;

     - discussed the past and current operations and financial condition and the
       prospects of Ocean, including information relating to certain strategic,
       financial and operational benefits anticipated from the merger, with
       senior executives of Ocean;

     - discussed the past and current operations and financial condition and the
       prospects of Devon, including information relating to certain strategic,
       financial and operational benefits anticipated from the merger, with
       senior executives of Devon;

     - reviewed the pro forma impact of the merger on Devon's earnings per
       share, cash flow, oil and gas reserves and production, consolidated
       capitalization and financial ratios;

     - reviewed the reported prices and trading activity for Ocean common stock
       and Devon common stock;

     - compared the financial performance of Ocean and Devon and the prices and
       trading activity of Ocean common stock and Devon common stock with that
       of certain other publicly-traded companies comparable with Ocean and
       Devon, respectively, and their securities;

                                        48


     - reviewed certain reserve reports prepared by Devon and Devon's
       independent reserve engineers;

     - reviewed certain reserve reports prepared by Ocean and Ocean's
       independent reserve engineers;

     - reviewed the financial terms, to the extent publicly available, of
       certain comparable business combination transactions deemed relevant;

     - participated in discussions and negotiations among representatives of
       Ocean and Devon and their financial and legal advisors;

     - reviewed a draft of the merger agreement and certain related documents;
       and

     - performed such other analyses and considered such other factors as Morgan
       Stanley deemed appropriate.

     In rendering its opinion, Morgan Stanley assumed and relied upon, without
independent verification, the accuracy and completeness of the information
reviewed by it for the purposes of its opinion. With respect to the financial
forecasts, including information relating to certain strategic, financial and
operational benefits anticipated from the merger, Morgan Stanley assumed that
they were reasonably prepared on bases reflecting the best currently available
estimates and judgments of the future financial performance of Ocean and Devon,
respectively.

     Morgan Stanley did not make any independent valuation or appraisals of the
assets or liabilities of Ocean or Devon, nor was it furnished with any such
appraisals. With respect to reserve estimates and reports referred to in bullets
2, 6, 9 and 10 above, Morgan Stanley is not an expert in the engineering
evaluation of oil and gas properties and, with Devon's consent, relied, without
independent verification, upon the internal reserve estimates prepared by Ocean
and Devon, respectively. In addition, Morgan Stanley assumed that the merger
would be completed in accordance with the terms set forth in the merger
agreement, including, among other things, that the merger will be treated as a
tax-free reorganization pursuant to the Internal Revenue Code of 1986, as
amended. Morgan Stanley's opinion is necessarily based on financial, economic,
market and other conditions in effect on, and the information made available to
it, as of February 23, 2003.

     The following is a summary of the material financial analyses performed by
Morgan Stanley in connection with its oral opinion and the preparation of its
written opinion dated February 23, 2003. These summaries of financial analyses
include information presented in tabular format. In order to fully understand
the financial analyses used by Morgan Stanley, the tables must be read together
with the text of each summary. The tables alone do not constitute a complete
description of the financial analyses. Morgan Stanley noted that Ocean's common
stock closed at a price of $18.60 per share on February 19, 2003. Based on the
0.414 exchange ratio and Devon's common stock closing price of $46.70 per share
on February 19, 2003, the implied acquisition price per Ocean common share of
$19.33 represented a premium of approximately 4%.

     Net Asset Valuation.  Morgan Stanley estimated Devon's and Ocean's net
asset value using two methodologies, one based on a discounted cash flow
analysis and the other based on a sum-of-parts analysis. For the discounted cash
flow analysis, Morgan Stanley used a combination of publicly available equity
research estimates and estimates of Devon's management, and both a 6.5% and 10%
discount rate, to calculate the present value of the future pre-tax cash flows
that Devon could be expected to generate from its proved reserves as well as
those of Ocean as of December 31, 2002. In addition, Devon's management provided
projections of the unlevered free cash flows that the combined company could be
expected to generate from its proved reserves during the fiscal years 2003
through 2017 and the value of the remaining proved reserves projected at 2017
based upon engineering projections prepared by the management of Devon. The
unlevered free cash flows and remaining value of proved reserves were then
discounted to obtain a present value using a discount rate of both 6.5% and 10%.
Morgan Stanley adjusted the estimated values for Devon's and Ocean's proved
reserves to include the value of certain other assets and liabilities of Devon
and Ocean, respectively. This discounted cash flow analysis resulted in an
implied exchange ratio of 0.408-0.462.

                                        49


     Morgan Stanley also estimated Devon's and Ocean's net asset value based on
a sum-of-parts analysis. For this analysis, Morgan Stanley calculated a range of
values for proved reserves segmented by region using $/BOE estimates for each
region. Morgan Stanley defined "Firm Value" as the sum of equity market
capitalization, total debt, minority interest and preferred stock, minus cash
and cash equivalents. Morgan Stanley defined "BOE" as one barrel equivalent of
oil assuming a conversion ratio of 6 Mcf of natural gas to one barrel of oil.

     The selected $/BOE for each region are as follows:



                                                              SELECTED VALUATION RANGE
                                                              ------------------------
                                                           
US Onshore..................................................        $6.00-$7.50
US Gulf of Mexico/Gulf Coast................................        $7.00-$9.00
Canada......................................................        $5.50-$7.00
West Africa.................................................        $3.50-$4.50
Azerbaijan..................................................        $4.50-$5.50
Other International.........................................        $3.50-$4.50


     Morgan Stanley applied the selected valuation range in the table above to
estimate the value of Devon's and Ocean's proved reserves as of December 31,
2002. Morgan Stanley adjusted the estimated values for Devon's and Ocean's
proved reserves to include the value of certain other assets and liabilities of
Devon and Ocean, respectively. The analysis resulted in an implied exchange
ratio of 0.419-0.487.

     Comparable Company Analysis.  Morgan Stanley reviewed selected financial
information, ratios and public market multiples for the following publicly
traded companies:

     - Burlington Resources, Inc.;

     - Anadarko Petroleum Corporation;

     - Apache Corporation;

     - Encana Corporation;

     - Kerr-McGee Corporation;

     - Unocal Corporation;

     - Murphy Oil Corporation;

     - EOG Resources, Inc.; and

     - Occidental Petroleum Corporation.

     The multiples and ratios for each of the selected companies were based on
the most recent publicly available information and on closing prices as of
February 19, 2003. Morgan Stanley defined "EBITDAX" as earnings before interest,
taxes, depletion, depreciation, amortization, and exploration expense. Morgan
Stanley defined "cash flow" as net income plus deferred taxes, depletion,
depreciation, amortization and exploration expense.

     The results of these analyses are as follows:



                                                              SELECTED VALUATION RANGE
                                                              ------------------------
                                                           
Price/2003 Estimated Cash Flow per Share....................         3.5x-5.0x
Firm Value/2003 Estimated EBITDAX...........................         4.5x-5.5x
Firm Value/Proved BOE.......................................        $7.00-$9.50


     Morgan Stanley applied the selected valuation range in the table above to
data based on First Call estimates and proved reserve estimates provided by
Devon's management. The analysis resulted in an implied exchange ratio of
0.326-0.529.

                                        50


     No company included in the comparable company analysis is identical to
Devon or Ocean. In evaluating the comparable companies, Morgan Stanley made
judgments and assumptions with regard to industry performance, general business,
economic, market and financial conditions and other matters, many of which are
beyond the control of Devon or Ocean, such as the impact of competition on the
business of Devon, Ocean and the industry generally, industry growth and the
absence of any adverse material change in the financial condition and prospects
of Devon or the industry or in the financial markets in general. Mathematical
analysis, such as determining the average or median, is not in itself a
meaningful method of using comparable company data.

     Precedent Corporate Transactions Analysis.  Using publicly available
information, Morgan Stanley performed an analysis of the following precedent
corporate transactions that were comparable to the merger in certain respects:

     - PanCanadian Energy/Alberta Energy;

     - Devon Energy/Mitchell Energy & Development;

     - Devon Energy/Santa Fe Snyder;

     - Anadarko Petroleum/Union Pacific Resources;

     - Devon Energy/PennzEnergy;

     - Santa Fe Energy/Snyder Oil; and

     - Ocean Energy/Seagull Energy.

     The results of these analyses are as follows:



                                                              SELECTED VALUATION RANGE
                                                              ------------------------
                                                           
Price/1-Year Forward Cash Flow per Share....................         3.5x-4.5x
Firm Value/1-Year Forward EBITDAX...........................         4.5x-5.5x
Firm Value/Proved BOE.......................................        $7.00-$9.00
Premiums Paid...............................................          15%-35%


     Morgan Stanley applied the selected valuation range in the table above to
data based on First Call estimates and proved reserve estimates provided by
Devon's management. The analysis resulted in an implied exchange ratio of
0.326-0.538.

     No transaction included in the comparison of precedent corporate
transactions analysis is identical to the merger. In evaluating the transactions
listed above, Morgan Stanley made judgments and assumptions with regard to
industry performance, general business, economic, market and financial
conditions and other matters, many of which are beyond the control of Devon or
Ocean, such as the impact of competition on Devon, Ocean and the industry
generally, industry growth and the absence of any adverse material change in the
financial condition and prospects of Ocean, Devon or the industry or in the
financial markets in general. Mathematical analysis, such as determining the
average or median, is not in itself a meaningful method of using precedent
corporate transaction data.

     Historical Exchange Ratio Analysis.  Morgan Stanley reviewed the daily
historical ratios of the closing prices per share of Ocean common stock divided
by the closing prices per share of Devon common stock for the period from
February 19, 2001 to February 19, 2003. Morgan Stanley calculated the average of
the historical ratios and computed the premium or discount represented by the
averages of the historical

                                        51


ratios for various periods over the 0.414 exchange ratio. The following table
presents the range of historical ratios over the periods covered compared to the
exchange ratio in the transaction:



                                                                  PREMIUM (DISCOUNT) TO 0.414
PERIOD                                              AVERAGE (X)       EXCHANGE RATIO (%)

1 Month...........................................     0.412                 (0.3)
3 Months..........................................     0.418                  1.0
6 Months..........................................     0.414                  0.0
1 Year............................................     0.424                  2.4
2 Years...........................................     0.413                 (0.2)


     Relative Contribution Analysis.  Morgan Stanley reviewed the relative
contributions of Ocean and Devon to the pro forma combined company based on
proved hydrocarbon reserves, hydrocarbon production, cash flow and EBITDAX using
three cases. The first case used 2002 historical data for both Devon and Ocean
prepared by Devon's management and Ocean's management. Based on this case, the
implied exchange ratio was 0.336 to 0.475. The second case used 2003 and 2004
data for the same metrics for Devon and Ocean based on publicly available data,
including the projections of securities analysts and First Call estimates. Based
on this case, the implied exchange ratio was 0.361 to 0.484. The third case used
Devon's management's projections for Devon and Ocean which were based on First
Call estimates for hydrocarbon pricing in 2003 and 2004. Based on this case, the
implied exchange ratio was 0.333 to 0.517.

     Morgan Stanley also reviewed the relative contributions of Ocean and Devon
based on the relative trading performance of each company's common stock for the
last twelve months through February 19, 2003. This analysis resulted in an
implied exchange ratio of 0.350 to 0.524.

     Pro Forma Financial Results.  Morgan Stanley reviewed the pro forma impact
of the merger on Devon's projected earnings per share and cash flow per share
for the fiscal years ended 2003, 2004 and 2005 based upon two cases. One case
was based on Devon's management's projections using First Call estimates for
hydrocarbon pricing in 2003 and 2004, and Devon's management's own pricing for
2005. The other case was based on publicly available data, including First Call
estimates, for both earnings per share and cash flow per share for both
companies. Based on the first case, the merger would be expected to be accretive
to Devon's earnings per share in 2003, but slightly dilutive to cash flow per
share in the same year and subsequently for both earnings per share and cash
flow per share in 2004 and 2005. In the second case, the merger would be
expected to be slightly dilutive to Devon's earnings per share and cash flow per
share in 2003 and 2004. There were no First Call projections for earnings per
share or cash flow per share for 2005.

     In connection with the review of the merger, Morgan Stanley performed a
variety of financial and comparative analyses for purposes of rendering its
opinion. The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. In arriving
at its opinion, Morgan Stanley considered the results of all of its analyses as
a whole and did not attribute any particular weight to any particular analysis
or factor considered by it. Furthermore, Morgan Stanley believes that selecting
any portion of its analyses or factors considered by it, without considering all
analyses and factors as a whole, would create an incomplete view of the process
underlying its opinion. In addition, Morgan Stanley may have given various
analyses and factors more or less weight than other analyses and factors and may
have deemed various assumptions more or less probable than other assumptions, so
that the ranges of valuations resulting from any particular analysis described
above should therefore not be taken to be Morgan Stanley's view of the actual
value of Devon or Ocean.

     In performing its analyses, Morgan Stanley made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of Ocean or Devon. Any
estimates contained in Morgan Stanley's analysis are not necessarily indicative
of future results or actual values, which may be significantly more or less
favorable than those suggested by such estimates. The analyses performed were
prepared solely as part of Morgan Stanley's

                                        52


analysis of the fairness from a financial view of the 0.414 exchange ratio
pursuant to the merger agreement to Devon and were conducted in connection with
the delivery by Morgan Stanley of its opinion dated February 23, 2003 to Devon's
board of directors. The analyses do not purport to be appraisals or to reflect
the prices at which Devon common stock or Ocean common stock actually may be
valued or the prices at which the Devon common stock or Ocean common stock may
actually trade in the marketplace.

     Morgan Stanley's opinion was one of the many factors taken into
consideration by Devon's board of directors in making its unanimous
determination to approve the merger agreement. Morgan Stanley's analyses
summarized above should not be viewed as determinative of the opinion of Devon's
board of directors with respect to the value of Devon or Ocean or of whether
Devon's board of directors would have been willing to agree to a different
exchange ratio or form of consideration. The 0.414 exchange ratio and other
terms of the merger agreement were determined through arm's length negotiations
between Ocean and Devon and were approved by Devon's board of directors. Morgan
Stanley provided advice to Devon during the course of the negotiations, but the
decision to enter into the merger agreement was solely that of Devon's board of
directors. Morgan Stanley did not recommend any specific exchange ratio to Devon
or that any given exchange ratio constituted the only appropriate exchange ratio
for the merger.

     Morgan Stanley is an internationally recognized investment banking and
advisory firm. Morgan Stanley, as part of its investment banking and financial
advisory business, is continuously engaged in the valuation of businesses and
securities in connection with mergers and acquisitions, negotiated
underwritings, competitive biddings, secondary distributions of listed and
unlisted securities, private placements and valuations for corporate and other
purposes. In the past, Morgan Stanley and its affiliates have provided financial
advisory and financing services for Devon and have received fees for the
rendering of these services. In the ordinary course of Morgan Stanley's
business, Morgan Stanley or its affiliates may from time to time trade in the
securities of or debt of Devon and Ocean for its own account, the accounts of
investment funds and other clients under the management of Morgan Stanley and
for the accounts of its customers and, accordingly, may at any time hold a long
or short position in these securities or debt.

     Pursuant to the engagement letter between Devon and Morgan Stanley, Devon
agreed to pay Morgan Stanley a $5 million fee for services rendered by Morgan
Stanley in connection with the merger, including Morgan Stanley's delivery of an
opinion as to the fairness from a financial point of view of the 0.414 exchange
ratio pursuant to the merger agreement to Devon as of the date on which the
merger agreement was signed. Devon has also agreed to reimburse Morgan Stanley
for its expenses incurred in performing its services. In addition, Devon has
agreed to indemnify Morgan Stanley and its affiliates, their respective
directors, officers, agents and employees and each person, if any, controlling
Morgan Stanley or any of its affiliates against certain liabilities and
expenses, including certain liabilities under the federal securities laws,
related to or arising out of Morgan Stanley's engagement and any related
transactions.

INTERESTS OF OCEAN'S EXECUTIVE OFFICERS AND DIRECTORS IN THE MERGER

     In considering the recommendation of Ocean's board of directors with
respect to the merger, Ocean stockholders should be aware that some of Ocean's
executive officers and directors may have interests in the merger that are
different from the interests of Ocean stockholders generally. The boards of
directors of both companies were aware of these interests and considered them in
approving and adopting the merger agreement and the merger that it contemplates.

  APPOINTMENT OF OCEAN'S DESIGNEES TO DEVON'S BOARD OF DIRECTORS

     Under the merger agreement,           ,           ,           , and
          , each of whom is currently a member of Ocean's board of directors,
are expected to be appointed to Devon's board of directors at the effective time
of the merger. Each of the Ocean-designated directors will hold office until his
respective successor is elected and qualified or until his earlier resignation
or removal. See the "Directors and Executive Officers of the Combined
Company -- Directors" section of this document for more information regarding
the Ocean designees.

                                        53


  APPOINTMENT OF JAMES T. HACKETT AS PRESIDENT AND CHIEF OPERATING OFFICER OF
  DEVON

     James T. Hackett, who is currently the Chairman, President and Chief
Executive Officer of Ocean, will be appointed President and Chief Operating
Officer of Devon at the effective time of the merger. Mr. Hackett's existing
employment agreement and severance agreement with Ocean were amended in
connection with the merger. The amendments have the effect of suspending until
May 2004 certain change-of-control provisions in the agreements that would
otherwise be triggered by the merger and would entitle Mr. Hackett to terminate
his employment for other than a "good reason," as provided in the agreements,
and receive a lump-sum cash payment and other benefits. Upon proper notice, Mr.
Hackett may elect to terminate his employment on May 1, 2004 and receive the
severance payments he would have received prior to the amendments to his
employment and severance agreements.

  OTHER INTERESTS

     Ocean's executive officers and directors also have the following interests
in the merger that may be different from Ocean stockholders' interests
generally:

     - Outstanding Ocean stock options and restricted stock awards held by
       Ocean's directors and executive officers (and all other Ocean employees)
       will vest at the effective time of the merger. At the effective time of
       the merger, options held by Ocean directors and executive officers
       relating to           shares of Ocean common stock will also vest.
       Outstanding Ocean stock options not exercised at that time will be
       converted into options to purchase shares of Devon common stock, subject
       to adjustment for the 0.414 exchange ratio.

     - After the merger, some Ocean officers may become officers of Devon.

     - The merger will trigger change-of-control provisions in Ocean's directors
       compensation plan. Upon completion of the merger, the existing Ocean
       directors who are not selected to serve on Devon's board of directors
       following the merger will be entitled to a lump-sum cash payment, which
       will generally be an amount equal to the product of the director's years
       of service (not less than one year nor more than five years) and the
       highest annual cash retainer that the director was paid. The aggregate of
       those lump-sum payments is expected to be about $1.4 million.

     - The merger will trigger change-of-control provisions in the employment
       agreements of some of Ocean's parent company and/or subsidiary officers,
       including:

      - Doss R. Bourgeois, Vice President -- Deepwater Facilities (Gulf of
        Mexico)

      - Clint P. Credeur, Vice President -- Reservoir Engineering (Gulf of
        Mexico)

      - Peggy T. d'Hemecourt, Vice President -- Human Resources

      - William S. Flores, Jr., Senior Vice President -- Worldwide Drilling

      - Stephen T. Laperouse, Vice President -- Land (Gulf of Mexico)

      - James H. Painter, Senior Vice President -- Gulf of Mexico and
        International Exploration

      - John J. Patton, Vice President, Associate General Counsel and Assistant
        Secretary

      - Robert K. Reeves, Executive Vice President, General Counsel and
        Secretary

      - John D. Schiller, Jr., Executive Vice President -- Exploration &
        Production

      - William L. Transier, Executive Vice President and Chief Financial
        Officer

      - Frank D. Willoughby, Vice President -- Financial Planning

     The merger will also constitute a "corporate change" for purposes of the
     employment agreements of those Ocean officers, entitling them to full
     vesting of their outstanding options and similar awards. In addition, if
     those Ocean officers do not continue their employment with the combined
     company after the merger, or if they leave the combined company for
     specified reasons, they may be entitled to
                                        54


     lump-sum cash payments and certain other benefits, such as continuing
     health insurance coverage. The cash payments will generally be equal to
     three times the sum of the Ocean officer's salary and bonus.

     - The merger will trigger change-of-control provisions in the severance
       agreements of the following Ocean parent company and/or subsidiary
       officers:

      - John H. Campbell, Jr., Senior Vice President -- North American Onshore
        Operations

      - Mario M. Coll, III, Vice President -- Operational Planning and Chief
        Information Officer

      - Scott A. Griffiths, Senior Vice President -- Exploration and
        International New Ventures

      - Kermit E. Reynolds, Senior Vice President -- Gulf of Mexico and
        International Operations

      - Robert L. Thompson, Vice President and Controller

     Those change-of-control provisions generally provide that a covered officer
     will be entitled to a lump-sum cash payment and certain other benefits if
     the officer's employment is "involuntarily terminated," as that term is
     defined in the severance agreements, within two years of the date on which
     the merger is completed. While the exact terms of the severance agreements
     differ, the lump-sum cash payment generally provides for the payment of the
     product of either 2 or 2.99 and the sum of the officer's annual salary and
     bonus.

     - The merger will cause full or partial vesting of outstanding awards under
       Ocean's executive supplemental retirement plan, which covers James T.
       Hackett, Robert K. Reeves, John D. Schiller, Jr., and William L.
       Transier, if a covered officer is terminated for certain reasons relating
       to the merger.

     - After the merger, Ocean will indemnify and hold harmless to the fullest
       extent permitted under law each current and former director and officer
       of Ocean, its subsidiaries and divisions against all losses pertaining to
       actions taken by them, or failures to act, while serving in those
       capacities before the merger.

     - For six years after the merger, Ocean will maintain its current policies
       of directors' and officers' liability insurance and fiduciary liability
       insurance, or policies no less favorable to the insured, covering acts or
       omissions before the merger.

     - The merger agreement generally requires Devon to honor Ocean's existing
       employee benefit plans and commitments in accordance with their terms
       until at least December 31, 2003. The merger agreement also provides
       assurances that Ocean officers and employees who become and remain full-
       time employees of the combined company after the merger will receive
       employee benefits no less favorable than those provided to similarly
       situated Devon employees until at least December 31, 2004. More
       information regarding Devon's obligations with respect to Ocean's
       existing employee benefit plans and commitments can be found in "The
       Merger Agreement -- Covenants and Other Agreements -- Employee Benefits"
       section of this document.

     Ocean's directors and executive officers beneficially owned, as of
          , 2003, about 4% of the outstanding shares of Ocean common stock. They
will be entitled to receive the same consideration as all other Ocean
stockholders.

     Devon's directors and executive officers did not beneficially own any
shares of Ocean stock as of           , 2003.

PENDING LITIGATION

     A lawsuit captioned Breakwater Partners, LP v. James T. Hackett, et. al.
(Case No. 2003-10161) was filed on February 27, 2003 in the District Court of
Harris County, Texas, naming as defendants Ocean and all of the members of
Ocean's board of directors. The complaint generally alleges that:

     - the 0.414 exchange ratio is inadequate and unfair to Ocean common
       stockholders; and

     - the defendants breached their fiduciary duties to Ocean stockholders,
       including the duty of care and the duty of loyalty, or aided and abetted
       in the breach of those fiduciary duties, by, among other things, (1)
       failing to conduct a "full and fair auction process or active market
       check;" (2) agreeing to the terms of the merger agreement, including a
       non-solicitation provision and the termination fee that is payable by
       Ocean to Devon under certain circumstances; (3) failing to make an
       informed decision; (4) failing to ensure that conflicts of interest are
       resolved in the best interests of Ocean's public stockholders; (5)
       personally benefiting from the merger; and (6) not appointing "any truly
       independent person or entity" to negotiate on behalf of Ocean
       stockholders.

     The complaint seeks class action status. It also seeks (1) injunctive
relief against completing the merger or, if the merger is completed, rescission
of the merger; (2) monetary damages in an unspecified amount; and (3) recovery
of the plaintiff's costs and attorneys' fees. The description of this lawsuit is
qualified in its entirety by reference to the complaint, which has been filed as
an exhibit to the registration statement of which this document is a part and is
incorporated into this document by reference.

     Ocean believes that the lawsuit is without merit and intends to defend
against it vigorously. We can provide no assurance that additional claims may
not be made or filed, the substance of which may be similar to the allegations
described above or that otherwise might arise from, or in connection with, the
merger agreement and the transactions it contemplates.

APPRAISAL RIGHTS

     The following summary of the provisions of Section 262 of the Delaware
General Corporation Law is not a complete statement of the law pertaining to
appraisal rights and is qualified in its entirety by reference to the full text
of Section 262 of the Delaware General Corporation Law, a copy of which is
attached to this document as Annex D and is incorporated into this summary by
reference.

  DEVON STOCKHOLDERS

     Devon stockholders are not entitled to appraisal rights in connection with
the merger.

  OCEAN STOCKHOLDERS

     Ocean common stockholders are not entitled to appraisal rights in
connection with the merger.

     Ocean convertible preferred stockholders are entitled to appraisal rights
in connection with the merger, if it is completed, and to receive in cash the
fair value of the Ocean convertible preferred stock as determined by the
Delaware Court of Chancery. Under Section 262 of the Delaware General
Corporation Law, not less than 20 days before Ocean's meeting, Ocean must notify
each of the holders of record of its Ocean convertible preferred stock as of the
record date that appraisal rights are available to them and include in the
notice a copy of Section 262. Ocean intends that this document constitutes that
required notice. An Ocean convertible preferred stockholder that elects to
exercise appraisal rights must:

     - deliver to Ocean, before the vote to adopt the merger agreement, written
       notice of the convertible preferred stockholder's identity and intention
       to demand payment of the fair value of the convertible preferred
       stockholder's convertible preferred shares (this written notice must be
       in addition to and separate from any proxy or vote against the adoption
       of the merger agreement; neither voting against adoption nor a failure to
       vote for adoption will constitute such a notice); and

                                        56


     - not vote in favor of adoption of the merger agreement (a failure to vote
       will satisfy the requirement, but a vote in favor of adoption of the
       merger agreement, by proxy or in person, will constitute a waiver of the
       convertible preferred stockholder's appraisal rights and will nullify any
       previously filed written notice of intent to demand payment).

An Ocean convertible preferred stockholder who fails to comply with either of
these conditions will have no appraisal rights with respect to the convertible
preferred stockholder's shares of Ocean convertible preferred stock. The shares
of Ocean convertible preferred stock with respect to which holders have
perfected their appraisal rights in accordance with Section 262 and have not
effectively withdrawn or lost their appraisal rights are referred to in this
document as the "dissenting convertible preferred shares."

     Any Ocean convertible preferred stockholder wishing to exercise appraisal
rights must be the record holder of the applicable convertible preferred shares
on the date the convertible preferred stockholder makes the written demand for
appraisal and must continue to hold the convertible preferred shares until
completion of the merger. In order to exercise appraisal rights with respect to
shares of Ocean convertible preferred stock, a convertible preferred stockholder
who elects to exercise appraisal rights should mail or deliver the convertible
preferred stockholder's written notice thereof to Ocean Energy, Inc., 1001
Fannin Street, Suite 1600, Houston, Texas 77002, Attention: Secretary. The
notice must be executed by, or on behalf of, the holder of record, whose name
should be stated as it appears on the stockholder's convertible preferred stock
certificate(s). The notice must identify the convertible preferred stockholder
and indicate the convertible preferred stockholder's intention to demand payment
of the fair value of the stockholder's convertible preferred shares. If the
convertible preferred shares are owned of record in a fiduciary capacity, such
as by a trustee, guardian or custodian, the demand should be made in that
capacity. If the convertible preferred shares are owned of record by more than
one person, as in a joint tenancy or tenancy in common, the demand should be
executed by or on behalf of all joint owners. An authorized agent, including one
or more joint owners, may execute a demand for appraisal on behalf of a record
holder; in the demand, however, the agent must identify the record owner or
owners and expressly disclose that the agent is executing the demand as an agent
for the record owner or owners. A record holder who holds convertible preferred
shares as nominee for several beneficial owners, such as a broker, may exercise
appraisal rights for the convertible preferred shares held for one or more
beneficial owners and not exercise rights for the convertible preferred shares
held for other beneficial owners. In this case, the written demand should state
the number of convertible preferred shares for which appraisal rights are being
demanded. When no number of convertible preferred shares is stated, the demand
will be presumed to cover all convertible preferred shares held of record by the
broker or nominee.

     Within ten days after the effective date of the merger, Ocean must mail
notice to all Ocean convertible preferred stockholders who have demanded
appraisal in compliance with the requirements of Section 262, notifying them of
the effective date. Within 120 days after the effective date, Ocean or any
holders of dissenting convertible preferred shares may file a petition in the
Delaware Court of Chancery for the appraisal of the dissenting convertible
preferred shares. However, any convertible preferred stockholder may, within 60
days after the effective date and prior to the filing of a petition, withdraw a
demand for appraisal and accept the merger consideration to which the
convertible preferred stockholder would have otherwise been entitled.

     When an Ocean convertible preferred stockholder files a petition for
appraisal, Ocean will file with the Register in Chancery, within 30 days of
service of the petition on Ocean, a verified list of the names and addresses of
the convertible preferred stockholders who have demanded appraisal. Upon the
order of the court, the Register in Chancery will then provide notice of the
hearing on the petition by mail and publication to the convertible preferred
stockholders who have demanded appraisal. At the hearing on such petition, the
court will determine the convertible preferred stockholders who have perfected
their appraisal rights. The court may require the holders of dissenting
convertible preferred shares to submit their stock certificates to the Register
in Chancery in order to note the pending appraisal proceedings on the stock
certificates; the failure of a convertible preferred stockholder to comply with
that direction may result in the court dismissing the proceedings as to that
convertible preferred stockholder.

                                        57


     Within 120 days after the effective date, any holder of dissenting
convertible preferred shares may, upon written request, receive from Ocean a
statement setting forth the aggregate number of convertible preferred shares not
voted in favor of adopting the merger agreement and with respect to which
demands for appraisals have been received and the aggregate number of holders of
such convertible preferred shares. Ocean must mail this statement to holders of
dissenting convertible preferred shares within ten days after receiving a
written request for this statement or within ten days after the vote to adopt
the merger agreement, whichever is later.

     If the merger is completed, each Ocean convertible preferred stockholder
who has perfected appraisal rights in accordance with Section 262 will be
entitled to be paid by Ocean the fair value in cash of the stockholder's
convertible preferred shares. Upon application of an Ocean convertible preferred
stockholder, the court may permit discovery and other pretrial proceedings. All
convertible preferred stockholders may participate in the appraisal proceedings
until the Court determines they are not entitled to appraisal. The Delaware
Court of Chancery will appraise the convertible preferred shares, determining
their fair value, exclusive of any element of value arising from the completion
or expectation of the merger, together with a fair rate of interest, if any, to
be paid upon the amount determined to be fair value. In determining the fair
value, the court may take into account all relevant factors and, upon such
determination, will then direct the payment of the fair value of the convertible
preferred shares, together with any interest, to Ocean convertible preferred
stockholders who have perfected their appraisal rights. Ocean will make payment
to those convertible preferred stockholders upon their surrender of the
certificates to Ocean.

     Stockholders considering seeking appraisal for their shares of Ocean
convertible preferred stock should note that the fair value of their convertible
preferred shares determined under Section 262 could be more, the same or less
than the consideration they would receive pursuant to the merger agreement if
they did not seek appraisal of their convertible preferred shares. The court may
determine the costs of the appraisal proceeding and allocate them among the
parties as the court deems equitable under the circumstances. Upon application
of a convertible preferred stockholder, the court may order all or a portion of
the expenses incurred by any convertible preferred stockholder in connection
with the appraisal proceeding, including, without limitation, reasonable
attorneys' fees and the fees and expenses of experts, to be charged pro rata
against the value of all convertible preferred shares entitled to appraisal. In
the absence of a determination or assessment by the court, each convertible
preferred stockholder bears its expenses.

     Any Ocean convertible preferred stockholder who demands an appraisal in
compliance with Section 262 will not, after completion of the merger, be
entitled to vote the stockholder's convertible preferred shares for any purpose
or be entitled to payment of dividends or other distribution on those
convertible preferred shares other than dividends or other distributions payable
as of a date on or before the date the merger is completed.

     If any Ocean convertible preferred stockholder who demands appraisal of the
stockholder's convertible preferred shares under Section 262 fails to perfect,
effectively withdraws or loses the right to appraisal, the stockholder's
convertible preferred shares will remain as shares of Ocean convertible
preferred stock and will remain outstanding as shares of the surviving
corporation of the merger in accordance with the terms of the merger agreement.
Dissenting convertible preferred shares lose their status as dissenting shares
if:

     - the merger is abandoned;

     - the stockholder seeking appraisal rights fails to make a timely written
       demand for appraisal;

     - after making a timely written demand for appraisal, the stockholder fails
       to continuously own the convertible preferred shares until the effective
       time of the merger;

     - neither Ocean nor a stockholder who has otherwise complied with Section
       262 files a petition for appraisal in the Delaware Court of Chancery
       within 120 days after the date on which the merger is completed; or

     - the stockholder delivers to Ocean, within 60 days of the date on which
       the merger is completed, or thereafter with Ocean's approval, a written
       withdrawal of the stockholder's demand for appraisal of

                                        58


       the dissenting convertible preferred shares, although no appraisal
       proceeding in the Court of Chancery may be dismissed as to any
       stockholder without the approval of the court.

     Failure to follow the steps required by Section 262 for perfecting
appraisal rights may result in the loss of appraisal rights. In view of the
complexity of the provisions of Section 262, Ocean convertible preferred
stockholders are encouraged to consult with their own advisors regarding their
appraisal rights.

REGULATORY REQUIREMENTS

     Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and the
rules promulgated thereunder by the Federal Trade Commission, the merger cannot
be completed until notifications have been given and certain information has
been furnished to the Federal Trade Commission and the Antitrust Division of the
Department of Justice and specified waiting period requirements have been
satisfied. Devon and Ocean filed notification and report forms under the
Hart-Scott-Rodino Act with the Federal Trade Commission and the Antitrust
Division on           , 2003. The waiting period under the Hart-Scott-Rodino Act
will expire at 11:59 p.m., Eastern Time, on           , 2003, unless a request
for additional information or documentary material is made by the Department of
Justice or Federal Trade Commission before that time or the waiting period is
terminated earlier.

     At any time before or after completion of the merger, the Antitrust
Division or the Federal Trade Commission or any state could take such action
under the antitrust laws as it deems necessary or desirable in the public
interest, including seeking to enjoin the completion of the merger, to rescind
the merger or to seek divestiture of particular assets of Devon or Ocean.
Private parties also may seek to take legal action under the antitrust laws
under certain circumstances. In addition, non-United States governmental and
regulatory authorities may seek to take action under applicable antitrust laws.
A challenge to the merger on antitrust grounds may be made and, if such a
challenge is made, it is possible that Devon and Ocean will not prevail.

                              THE MERGER AGREEMENT

     The following is a summary of the material terms of the merger agreement.
It is qualified in its entirety by reference to the merger agreement, a copy of
which is attached to this document as Annex A and is incorporated into this
document by reference. You should read the merger agreement because it, and not
this document, is the legal document that governs the terms of the merger.

STRUCTURE OF THE MERGER

     At the effective time of the merger, Devon NewCo Corporation, a newly
formed, nominally capitalized Delaware corporation that is wholly owned by
Devon, will merge with and into Ocean. Ocean will be the surviving corporation
in the merger, and will become a wholly owned subsidiary of Devon. Devon may
substitute another of its wholly owned subsidiaries to be a party to the merger
in place of Devon NewCo as long as the substitution does not delay either the
Devon meeting or the Ocean meeting.

     Ocean's certificate of incorporation will be amended at the effective time
of the merger and, as so amended, will be the surviving corporation's
certificate of incorporation until duly amended. The amendments are designed to
make the surviving corporation's certificate of incorporation similar to the
organizational documents of Devon's other wholly owned subsidiaries. Devon
NewCo's bylaws will be the surviving corporation's bylaws until duly amended.
The directors of Devon NewCo at the effective time of the merger will be the
surviving corporation's directors.

     Assuming Devon's board of directors is to consist of 13 directors at the
effective time of the merger, Devon must appoint four current Ocean directors
designated by Ocean to Devon's board of directors at the effective time,
provided that each Ocean designee is acceptable to Devon in its sole discretion.
See the "Directors and Executive Officers of the Combined Company -- Directors"
section of this document for information on the Ocean directors who will be
appointed to Devon's board of directors. The number of Ocean designees may be
adjusted upward or downward if the size of Devon's board of directors increases

                                        59


or decreases before the merger is completed. The Ocean designees will be
allocated as evenly as possible among the different classes of Devon directors.
In addition, James T. Hackett will become Devon's President and Chief Operating
Officer at the effective time of the merger. J. Larry Nichols will remain
Devon's Chairman and Chief Executive Officer at the effective time of the
merger. See "The Merger -- Interests of Ocean's Executive Officers and Directors
in the Merger" section of this document.

WHEN THE MERGER BECOMES EFFECTIVE

     Ocean and Devon NewCo will execute and file a certificate of merger with
the Delaware Secretary of State on the first business day after the day on which
the last condition to completing the merger is satisfied or waived or at such
other time as Devon and Ocean may agree. The merger will become effective at the
time and on the date on which the certificate of merger is filed or such other
time and date on which the parties agree and specify in the certificate of
merger. That time is referred to as the "effective time of the merger."

CONVERSION OF OCEAN STOCK AND STOCK OPTIONS

     At the effective time of the merger:

     - each outstanding share of Ocean common stock, other than shares owned by
       Devon, Devon NewCo, Ocean or their respective subsidiaries, will be
       converted into 0.414 of a share of Devon common stock;

     - each outstanding share of Ocean convertible preferred stock, other than
       convertible preferred shares held by Ocean convertible preferred
       stockholders who validly exercise their appraisal rights under Delaware
       law, shall (1) remain outstanding as one share of convertible preferred
       stock of the surviving corporation and (2) after the effective time of
       the merger, be convertible into Devon common stock instead of Ocean
       common stock, giving effect to the 0.414 exchange ratio, and will have
       voting rights in Devon on an as-converted basis instead of voting rights
       in Ocean;

     - each outstanding share of Ocean convertible preferred stock held by Ocean
       convertible preferred stockholders who validly exercise their appraisal
       rights under Delaware law will be treated as described in "The
       Merger -- Appraisal Rights" section of this document;

     - shares of Ocean common stock owned by Devon, Devon NewCo, Ocean or any of
       their respective subsidiaries will be canceled and retired without any
       payment; and

     - each share of Devon NewCo common stock will be converted into one share
       of common stock of the surviving corporation.

     If, before the effective time of the merger, the issued and outstanding
shares of Devon or Ocean common stock are changed into a different number of
shares as a result of a stock split, reverse stock split, stock dividend, stock
distribution, reorganization, recapitalization, reclassification or similar
event, an appropriate adjustment will be made to the 0.414 exchange ratio.

     Each outstanding option to purchase Ocean common stock granted under
Ocean's stock plans that is unexercised as of the effective time of the merger
will be assumed by Devon at the effective time of the merger and will become an
option to purchase a number of shares of Devon common stock equal to the number
of Ocean shares covered by the option multiplied by 0.414 (or, if the exchange
ratio is adjusted, the new exchange ratio), with any fractional amount rounded
to the next lowest share, for each share of Ocean common stock covered by the
option before the merger. After conversion, the exercise price per share of
Devon common stock subject to each option will equal the pre-conversion exercise
price per share of Ocean common stock subject to each option divided by 0.414
(or, if the exchange ratio is adjusted, the new exchange ratio), with any
fractional amount rounded to the next highest cent.

     For a description of Devon's and Ocean's common stock and a description of
the comparative rights of holders of Devon common stock and Ocean common stock,
see the "Comparison of the Rights of Ocean and Devon Stockholders" section of
this document.

                                        60


EXCHANGE OF SHARES; FRACTIONAL SHARES

     Exchange Agent.  At or prior to the effective time of the merger, Devon
will authorize the exchange agent to credit a sufficient number of shares of
Devon common stock to direct registration (book-entry) accounts maintained by
Devon's transfer agent, or to issue certificates representing those shares, to
effect the conversion of Ocean common stock into the Devon common stock to be
issued in the merger. Devon will also make funds available to the exchange agent
from time to time after the effective time of the merger as needed to pay any
dividends or other distributions declared by Devon on its common stock with a
record date after the effective time of the merger and a payment date on or
before the date the relevant shares of Ocean common stock are surrendered.

     At the effective time of the merger, the stock transfer books of Ocean will
be closed and no further issuances or transfers of shares of Ocean common stock
will be made. If, after the effective time, valid Ocean stock certificates are
presented to the surviving corporation for any reason, they will be cancelled
and exchanged as described above to the extent allowed by applicable law.

     Exchange of Shares.  If you own Ocean common stock, the exchange agent will
mail to you a transmittal letter and instructions explaining how to surrender
your shares of Ocean common stock to the exchange agent after the effective time
of the merger.

  OCEAN STOCK CERTIFICATES SHOULD NOT BE RETURNED WITH THE ENCLOSED PROXY CARD.
  A TRANSMITTAL LETTER AND ACCOMPANYING INSTRUCTIONS WILL BE PROVIDED TO OCEAN
  STOCKHOLDERS FOLLOWING THE MERGER.

     Ocean stockholders who deliver a properly completed and signed transmittal
letter and any other documents required by the instructions to the transmittal
letter to the exchange agent, together with their Ocean stock certificates, to
the extent their Ocean common stock is evidenced by stock certificates, will
receive:

     - the number of whole shares of Devon common stock to which each holder is
       entitled in accordance with the merger agreement; and

     - after giving effect to any required tax withholdings, a check in the
       aggregate amount of:

      - the cash proceeds received from the sale by the exchange agent of any
        fractional shares of Devon common stock; and

      - any cash dividends and any other dividends or other distributions
        declared by Devon on its common stock with a record date after the
        effective time of the merger and a payment date on or before the date
        the Ocean stockholder surrendered its stock certificate.

     Devon uses a direct registration (book-entry) program with respect to
record ownership of Devon common stock. Direct registration is a service that
allows shares to be owned, reported and transferred electronically without
having a physical stock certificate issued. Ownership of the shares is recorded
in the name of the owner electronically on Devon's books and records. Direct
registration is intended to alleviate problems relating to stolen, misplaced or
lost stock certificates and to reduce the paperwork relating to the transfer of
ownership of Devon common stock. Under direct registration, the voting, dividend
and other rights and benefits of holders of Devon common stock remain the same
as with holders of certificated shares.

     Ocean stockholders who deliver a properly completed and signed transmittal
letter and any other documents required by the instructions to the transmittal
letter to the exchange agent, together with their Ocean stock certificates, to
the extent their Ocean common stock is evidenced by stock certificates, will be
issued the appropriate number of shares of Devon common stock through direct
registration. As soon as reasonably practicable following the crediting of
shares to their respective book-entry account, Ocean common stockholders will
receive account statements from Devon's transfer agent evidencing their
holdings, as well as general information on the book-entry form of ownership
through Devon's direct registration system. You are not required to maintain a
book-entry account, and you may at any time obtain a physical stock certificate
for all or a portion of your shares of Devon common stock received in

                                        61


the merger at no cost to you. Instructions describing how you can obtain stock
certificates will be included with the account statement mailed to you and can
also be obtained upon request from Devon's transfer agent.

     If your Ocean common stock is evidenced by a stock certificate, you should
surrender that certificate for exchange after the effective time of the merger.
Until you deliver a properly completed and signed transmittal letter and any
other documents required by the instructions to the transmittal letter to the
exchange account, together with your Ocean stock certificates, to the extent
your Ocean common stock is evidenced by stock certificates, dividends or other
distributions declared with a record date after the effective time of the merger
will accrue, but will not be paid, on shares of Devon common stock that you are
entitled to receive as a result of the conversion of your shares of Ocean common
stock. No interest will be paid or accrue on:

     - the amount of cash to be received in lieu of fractional shares of Devon
       common stock; or

     - any cash dividends and any other dividends or other distributions
       declared by Devon on its common stock with a record date after the
       effective time of the merger and a payment date on or before the date the
       Ocean stock certificate is surrendered.

     The exchange agent will deliver to Devon any shares of Devon common stock
to be issued in the merger or funds received from the sale of fractional shares
in connection with the merger or to pay dividends or other distributions on
shares of Devon common stock to be issued in the merger that are not claimed by
former Ocean stockholders within one year after the effective time of the
merger. Thereafter, Devon will act as the exchange agent and former Ocean
stockholders may look only to Devon for payment of their shares of Devon common
stock, cash in lieu of fractional shares and unpaid dividends and distributions.
None of Devon, the surviving corporation, the exchange agent or any other person
will be liable to any former Ocean stockholder for any amount properly delivered
to a public official pursuant to applicable abandoned property, escheat or
similar laws. To the extent permitted by applicable law, any amount that would
escheat or become the property of any governmental entity shall, immediately
prior thereto, become the property of Devon free and clear of all claims or
interests of any person previously entitled thereto.

     If any shares of Devon common stock are to be issued in a name other than
that in which the Ocean common stock exchanged for such shares is registered,
the person requesting the exchange must (1) pay any transfer or other taxes
required by reason of the issuance of shares of Devon common stock in a name
other than that of the registered holder of the surrendered shares of Ocean
common stock or (2) establish to the satisfaction of Devon or the exchange agent
that such tax has been paid or is not applicable.

     Fractional Shares.  No fractional shares of Devon common stock will be
issued to Ocean stockholders. After the effective time of the merger, the
exchange agent will determine the number of shares of Devon common stock equal
to the difference, which we refer to as excess shares, between (1) the total
number of shares of Devon common stock that would be issuable to Ocean
stockholders if fractional shares were being issued in the merger and (2) the
total number of shares of Devon common stock issuable to Ocean stockholders
taking into account that fractional shares will not be issued in the merger.

     The exchange agent will sell on the American Stock Exchange, in round lots
to the extent practicable, the excess shares as soon as practicable after the
effective time of the merger. The surviving corporation will pay all
commissions, transfer taxes and other out-of-pocket transaction costs of selling
the excess shares. The exchange agent will hold in trust for the benefit of
Ocean stockholders the proceeds of the sale of excess shares. Instead of
fractional shares, each Ocean stockholder otherwise entitled to a fractional

                                        62


share of Devon common stock will receive, in cash and without interest, an
amount determined by the following formula:


                          
                                Fractional share of Devon common stock to which the Ocean
Aggregate proceeds from         stockholder otherwise would be entitled
the sale of the excess    x     ------------------------------------------------------------
shares                          Aggregate amount of fractional shares of Devon common stock
                                to which all Ocean stockholders otherwise would be entitled


     Lost, Stolen or Destroyed Certificates.  If an Ocean stock certificate has
been lost, stolen or destroyed, the exchange agent will issue the shares of
Devon common stock properly issuable in accordance with the merger agreement
upon receipt of (1) an affidavit of that fact by the person claiming that the
certificate is lost, stolen or destroyed and (2) appropriate and customary
indemnification or the posting of a bond in the form customarily required by
Devon to indemnify against any claim that may be made against it with respect to
the lost, stolen or destroyed certificate.

     Affiliates.  Shares of Ocean common stock surrendered for exchange by
certain affiliates of Ocean will not be exchanged until Devon has received a
written agreement of the kind described below under the heading "Covenants and
Other Agreements -- Affiliate Agreements."

        reorganization within the meaning of section 368(a) of the Internal
        Revenue Code; and

      - in the case of the opinion to Ocean, no gain or loss will be recognized
        by Ocean or its stockholders to the extent that they receive Devon
        common stock in exchange for shares of Ocean common stock, and, in the
        case of the opinion to Devon, no gain or loss will be recognized by any

satisfied if the necessary stockholder approvals have been obtained and the law
allows the company to do so.

REPRESENTATIONS AND WARRANTIES

     The merger agreement contains representations and warranties by each of
Devon and Ocean as to itself and its subsidiaries, many of which provide that
the representation and warranty does not extend to matters where the failure of

     - in Devon's case only, the inapplicability of Devon's stockholder rights

     For purposes of the merger agreement, material adverse effect with respect
to any party means a material adverse effect on that party's (1) business,

extent any adverse effect results from (a) general economic, regulatory or
political conditions or changes, (b) financial or securities markets
fluctuations or conditions, (c) conditions or changes affecting the oil and gas
industry generally, (d) the merger or its announcement, or compliance with the
covenants in the merger agreement, or (e) stockholder class action litigation
arising from breach of fiduciary duty claims relating to the merger agreement,
the effect will not be considered a material adverse effect for purposes of the
merger agreement.

     Operating Covenants.  Prior to the merger and unless the other party has

       return has been filed, except as may be required by applicable law;

       property in connection with any indebtedness, except in the ordinary
       course of business;

     - not to make or commit to make aggregate capital expenditures in excess of

       million;

     - not to take any action that is likely to delay materially or adversely
       affect any party's ability to obtain any consent or approval of any

     - not to terminate, amend, modify or waive any provision of any
       confidentiality or standstill agreement to which it is a party and to
       enforce to the fullest extent permitted under applicable law the
       provisions of those agreements, unless, in the good faith opinion of its
       board of directors after consultation with its outside legal counsel,
       taking, or failing to take, the action would be inconsistent with the
       fiduciary duties of its board of directors and only then if taking, or
       failing to take, the action would not otherwise violate the merger
       agreement;

                                        66


     - not to enter into or amend any agreement with any holder of its capital

       2003 for which the volume hedged is more than 65% of Devon's estimated
       production of proved reserves of these commodities during that period;
       (2) any period in 2004 for which the volume hedged is more than 35% of
       Ocean's or Devon's, as the case may be, estimated production of proved
       reserves of these commodities during that period; or (3) any period after
       December 31, 2004;

     - not to amend its stockholder rights plan, redeem any rights subject to
       its stockholder rights plan or exempt any third party from the other
       provisions of its stockholder rights plan;

     - not to split, combine, subdivide or reclassify its outstanding stock;

     - not to purchase any common stock of the other party;

     - not to do business in any country in which it was not doing business as
       of the date of the merger agreement;

     - not to enter into any joint venture, partnership or other joint business
       venture in which the total fair market value of its investments and
       commitments exceed $50 million; and

     - not to agree in writing or otherwise to take any of the foregoing
       actions.

     Other Acquisition Proposals.  In the merger agreement, each of Devon and
Ocean has agreed that it and its subsidiaries:

     - will not, and will not permit any of their officers, directors,
       employees, agents or representatives to, solicit, initiate or encourage
       any inquiry, proposal or offer for a third-party tender offer, merger,
       consolidation, business combination or similar transaction involving any
       assets or class of capital stock of Devon or Ocean, as the case may be,
       or any acquisition of 10% or more of the capital stock of Devon or Ocean,
       as the case may be, or involving a business or assets that constitute 10%
       or more of the net revenues, net operating income or assets, taken as a
       whole, of Devon or Ocean, as the case may be, in a single transaction or
       a series of related transactions, or participate in any discussions or
       negotiations concerning such an acquisition proposal; and

     - will immediately cease any existing negotiations with any third parties
       with respect to any of the above transactions.

     As long as Devon or Ocean, as the case may be, (1) provides notice to the
other party within 24 hours that it has received an unsolicited request for
information or an acquisition proposal identifying the person requesting the
information or making the acquisition proposal and stating the material terms
and conditions of the acquisition proposal, and (2) continues to provide updates
to the other party as to material developments within 24 hours, Devon's and
Ocean's agreement regarding other acquisition proposals is subject to the
following exceptions:

     - Devon or Ocean, or Devon's or Ocean's board of directors, may respond
       publicly to a third-party tender offer as required by the federal
       securities laws;

     - Devon or Ocean, or Devon's or Ocean's board of directors, may make
       disclosures to its stockholders if, in the good faith judgment of its
       board of directors, the failure to make those disclosures would be
       inconsistent with its fiduciary duties under applicable law or stock
       exchange rules; and

     - Devon or Ocean, or Devon's or Ocean's board of directors, may provide
       information on a confidential basis to any person, or have negotiations
       or discussions with any person, who makes an

                                        67


       unsolicited bona fide acquisition proposal with respect to all of its
       outstanding shares of capital stock or all or substantially all of its
       assets, provided that:

      - Devon's or Ocean's board of directors, as the case may be, in good faith
        (1) after consultation with its financial advisors and taking into
        account the likelihood of consummation, determines that the acquisition
        proposal is reasonably likely to result in a transaction that is more
        favorable from a financial point of view to holders of Devon or Ocean
        common stock, as the case may be, than the merger, and (2) after
        consultation with its outside legal counsel, determines that the failure
        to respond to the information request or to engage in discussions would
        be inconsistent with its fiduciary obligations under applicable law; and

      - neither Devon nor Ocean may not enter into any agreement, other than a
        confidentiality or standstill agreement permitted by the terms of the
        merger agreement, with respect to an acquisition proposal prior to the
        termination of the merger agreement.

     Withdrawal or Change of Recommendation to Stockholders.  Prior to obtaining
their respective stockholders' approval, Devon's or Ocean's board of directors
may withdraw or adversely change its recommendation to stockholders to vote for
the merger, or recommend that stockholders vote instead for a competing
transaction, but only if the board determines in good faith, after consultation
with its outside legal counsel, that the failure to do so would be inconsistent
with its fiduciary obligations under applicable law. At least two business days
prior to taking one of the two actions described in the previous sentence, the
party seeking to take the action must provide to the other party written notice
of its intention to take the action so as to allow the other party to propose
modifications to the merger agreement designed to eliminate the need for the
board of directors to take such action.

     Devon or Ocean, as the case may be, will have an option, exercisable within
two business days after it receives written notice from the other party that its
board of directors has withdrawn or adversely changed its original
recommendation or recommended a competing transaction, to require the other
party to (1) submit to a vote the matter to be voted on by that party's
stockholders and (2) disclose to that party's stockholders the circumstances
under which the matter is being submitted to a vote. If Devon or Ocean, as the
case may be, does not exercise this option, then the other party may terminate
the merger agreement upon payment of a termination fee as described in the
"-- Termination Fees and Expenses" section of this document.

     Other Agreements Relating to the Period Before the Effective Time.  The
merger agreement contains additional agreements between Devon and Ocean relating
to, among other things:

     - the preparation, filing and distribution of this document and Devon's
       filing of the registration statement of which this document is a part;

     - convening and holding the Devon and Ocean stockholder meetings;

     - access to information respecting the other party;

     - cooperation regarding filings with governmental and other agencies and
       organizations;

     - using their reasonable best efforts to satisfy the conditions to closing;

     - each party refraining from, without the other party's prior written
       consent, committing to any divestitures, licenses, hold separate
       agreements or similar matters, and each party committing and consenting
       to, and using its reasonable best efforts to, effect any divestiture,
       license, hold separate arrangement or similar matter that (1) is required
       by any regulatory body as a condition to resolving its objections to the
       merger or obtaining its approval of the merger and (2) would not
       reasonably be expected to have a material adverse effect on Devon or
       Ocean;

     - public announcements;

     - the listing on the American Stock Exchange of the Devon common stock to
       be issued in the merger;

                                        68


     - actions or omissions that would result in the merger not qualifying as a
       reorganization under section 368(a) of the Internal Revenue Code; and

     - the coordination of dividend record and payment dates so that Ocean
       stockholders do not fail to receive a dividend in any calendar quarter or
       receive dividends on both Ocean common stock and Devon common stock
       received in the merger in any calendar quarter.

     Employee Benefits.  The merger agreement provides that Devon will honor
Ocean's employee benefit plans and commitments entered into prior to the date of
the merger agreement, provided that Devon may modify any such plan or commitment
in accordance with its terms subject to some exceptions for Ocean employees in
the United States.

     The merger agreement specifies that certain Ocean employees may be entitled
to severance benefits and certain other employee benefits as a result of the
merger under an existing Ocean severance plan. Devon has agreed that the
surviving corporation will not modify the Ocean severance plan with respect to
severance benefits and other employee benefits provided to Ocean employees as a
result of certain involuntary terminations of employment occurring on or prior
to the one year anniversary of the effective time of the merger.

     Devon has agreed that, until at least December 31, 2003, the surviving
corporation will maintain Ocean's medical, health, life and disability insurance
plans, and Ocean's deferred compensation and retirement plans, as in effect at
the effective time of the merger and, prior to January 1, 2004, will not amend
any of those plans to reduce any benefit provided. In addition, if Devon
materially modifies during 2004 the benefits of Ocean employees who become or
remain regular full-time employees of Devon, Devon has agreed to provide those
employees for the remainder of 2004 with benefits no less favorable than those
provided to similarly situated Devon employees. Ocean employees who become
participants in Devon's employee benefit plans will be given credit under the
plans for their prior service with Ocean for purposes of eligibility, vesting
and benefit determination, with some exceptions.

     Devon has agreed that the surviving corporation will not amend Ocean's
executive supplemental retirement plan in any manner that would adversely affect
the continued vesting of any Ocean employee in the United States that is a
member of the plan, and that each plan member will receive credit under the plan
for his or her service with the surviving corporation or Devon. In addition, if
the surviving corporation terminates the plan, Devon has agreed that each plan
member employed by the surviving corporation or Devon at the time the plan is
terminated will be fully vested in the plan upon its termination.

     Any non-qualified stock options that are (1) held by an Ocean officer or
employee whose service is terminated after the effective time of the merger and
who is eligible to receive severance benefits as a result of the termination and
(2) exercisable on the date of the individual's termination, will continue to be
exercisable during the one-year period following the individual's termination.

     Affiliate Agreements.  Ocean has agreed to use its reasonable best efforts
to cause its affiliates, as defined by Rule 145 under the Securities Act of
1933, to enter into written agreements prior to the effective time of the merger
that restrict their ability to sell, pledge, transfer or otherwise dispose of
any shares of Devon common stock issued to them in connection with the merger:

     - in compliance with Rule 145 under the Securities Act of 1933;

     - pursuant to an effective registration statement under the Securities Act
       of 1933; or

     - in reliance upon a written opinion of counsel delivered to Devon in a
       form and substance reasonably acceptable to Devon to the effect that such
       sale, pledge, transfer or other disposition is exempt from registration
       under the Securities Act of 1933.

     Indemnification and Insurance.  After the merger, Devon will cause the
surviving corporation to indemnify and hold harmless to the fullest extent
permitted under applicable law each person who is, or has been at any time prior
to the effective time of the merger, an officer or director of Ocean or any
Ocean subsidiary or division and each person who served at the request of Ocean
as a director, officer,

                                        69


trustee or fiduciary of any other entity. Those persons will be indemnified to
the fullest extent permitted by law against all losses, including fees and
expenses of counsel, arising out of or pertaining to actions taken by them, or
failures to act, while serving in those capacities, whether claimed before or
after the effective time of the merger. The rights to indemnification for such
persons in Ocean's certificate of incorporation, bylaws and any indemnification
agreement with respect to matters occurring through the effective time of the
merger will survive the merger and continue in full force and effect for a
period of six years after the merger.

     The surviving corporation will maintain directors' and officers' liability
insurance for six years after the effective time of the merger to cover persons
who are or were covered by Ocean's existing directors' and officers' liability
insurance policies at any time before the effective time of the merger. The
terms of the insurance will be substantially no less advantageous to such
persons than the existing insurance with respect to acts or omissions prior to
the effective time of the merger. However, the surviving corporation will not be
required to pay annual premiums in excess of 250% of the 2003 annual premium
paid by Ocean, but will be required to purchase as much coverage as reasonably
practicable for such amount. Devon has the right to cause Ocean's directors and
officers liability insurance to be extended by obtaining a six-year "tail"
policy on terms no less advantageous than Ocean's existing directors and
officers liability insurance.

TERMINATION

     Before the effective time of the merger, the merger agreement may be
terminated:

     - by mutual written consent of Devon and Ocean;

     - by Devon or Ocean, if:

      - the merger is not completed by September 30, 2003, so long as the party
        seeking to terminate did not prevent the merger from occurring by
        failing to perform or observe its obligations under the merger agreement
        in any material respect;

      - Devon's stockholders fail to approve at Devon's special meeting the
        issuance of shares of Devon common stock in the merger; or

      - Ocean's stockholders fail to adopt the merger agreement at Ocean's
        special meeting;

      - there is a legal prohibition to completing the merger that has become
        final and non-appealable, so long as the party seeking termination has
        complied with its obligations under the merger agreement to attempt to
        remove the prohibition or otherwise used its reasonable best efforts to
        remove the prohibition;

     - by Devon, if Ocean breaches any of its representations, warranties or
       agreements in the merger agreement or if any of Ocean's representations
       or warranties becomes untrue resulting in a condition of the merger not
       being satisfied, and the breach is not curable or is not cured within 30
       days, provided that Devon is not also in material breach of the merger
       agreement;

     - by Ocean, if Devon breaches any of its representations, warranties or
       agreements in the merger agreement or if any of Devon's representations
       or warranties becomes untrue resulting in a condition of the merger not
       being satisfied, and the breach is not curable or is not cured within 30
       days, provided that Ocean is not also in material breach of the merger
       agreement;

     - by Devon, if:

      - prior to the adoption by Ocean's stockholders of the merger agreement,
        Ocean's board of directors withdraws or adversely changes its
        recommendation to stockholders, or recommends that stockholders vote
        instead for a competing transaction, or resolves to do so, but Devon
        loses this right if (1) Devon has not exercised its option to require
        Ocean to submit the matter to a vote by Ocean's stockholders or (2) the
        withdrawal or adverse change is no longer in effect because Devon and
        Ocean are proceeding with the transaction under modified terms; or

                                        70


      - prior to the approval by Devon's stockholders of the issuance of shares
        of Devon common stock in the merger, (1) Devon's board of directors
        withdraws or adversely changes its recommendation to stockholders, or
        recommends that stockholders vote instead for a competing transaction,
        or resolves to do so, (2) Ocean had the option to require Devon to
        submit to the matter to a vote by Devon's stockholders and (3) Ocean did
        not exercise that option;

     - by Ocean, upon payment of the termination fee described below, if:

      - prior to the approval by Devon's stockholders of the issuance of shares
        of Devon common stock in the merger, Devon's board of directors
        withdraws or adversely changes its recommendation to stockholders, or
        recommends that stockholders vote instead for a competing transaction,
        or resolves to do so, but Ocean loses this right if (1) Ocean has not
        exercised its option to require Devon to submit the matter to a vote by
        Devon's stockholders or (2) the withdrawal or adverse change is no
        longer in effect because Devon and Ocean are proceeding with the
        transaction under modified terms; or

      - prior to the adoption by Ocean's stockholders of the merger agreement,
        (1) Ocean's board of directors withdraws or adversely changes its
        original recommendation to stockholders, or recommends that stockholders
        vote instead for a competing transaction, or resolves to do so, (2)
        Devon had the option to require Ocean to submit the matter to a vote by
        Ocean's stockholders and (3) Devon did not exercise that option.

TERMINATION FEES AND EXPENSES

     Termination Fees and Expenses Potentially Payable by Ocean.  Ocean has
agreed to pay Devon a $139 million termination fee and to reimburse Devon for
expenses incurred in connection with the merger agreement up to a maximum of $10
million if:

     - Devon or Ocean terminates the merger agreement after (1) (a) the public
       announcement of a competing transaction involving Ocean or (b) Ocean's
       board of directors withdrew or changed, in a manner adverse to Devon, its
       recommendation to its stockholders, or recommended that its stockholders
       vote instead for a competing transaction and (2) Devon elected to
       exercise its option to require a vote of Ocean's stockholders on the
       merger agreement and Ocean's stockholders failed to adopt the merger
       agreement at a meeting duly convened for that purpose; or

     - Devon or Ocean terminates the merger agreement before Ocean's
       stockholders adopt the merger agreement and after Ocean's board of
       directors withdraws or changes, in a manner adverse to Devon, its
       recommendation to its stockholders, or recommends that its stockholders
       vote instead for a competing transaction and Devon does not elect to
       exercise its option to require a vote of Ocean's stockholders on the
       merger agreement.

     However, instead of the $139 million termination fee described above, Ocean
has agreed to pay Devon a $69.5 million termination fee (and to reimburse Devon
for expenses incurred in connection with the merger agreement up to a maximum of
$10 million) if Devon or Ocean terminates the merger after (1) a competing
transaction involving Ocean is publicly announced, but Ocean's board of
directors does not withdraw or change, in a manner adverse to Devon, its
recommendation to stockholders, or recommend that stockholders vote instead for
a competing transaction, and (2) Ocean's stockholders fail to adopt the merger
agreement after this public announcement. If, within 12 months after the merger
agreement is terminated under those circumstances, Ocean agrees to merge with a
third party whereby Ocean is not the surviving corporation (or, if Ocean is the
surviving corporation, Ocean stockholders immediately prior to the merger hold
less than 50% of the voting stock of Ocean immediately after the merger), or a
third party acquires or agrees to acquire at least 50% of Ocean's voting stock
or assets, then Ocean must pay Devon an additional $69.5 million termination
fee.

     Ocean has agreed to reimburse Devon for expenses incurred in connection
with the merger agreement up to a maximum of $10 million if Devon or Ocean
terminates the merger after Ocean's stockholders fail to adopt the merger
agreement even though Ocean's board of directors has not withdrawn or changed,
in a

                                        71


manner adverse to Devon, its original recommendation to its stockholders, or
recommended that its stockholders vote instead for a competing transaction.

     Termination Fees and Expenses Potentially Payable by Devon.  Devon has
agreed to pay Ocean a $139 million termination fee and to reimburse Ocean for
expenses incurred in connection with the merger agreement up to a maximum of $10
million if:

     - Devon or Ocean terminates the merger agreement after (1) (a) the public
       announcement of a competing transaction involving Devon or (b) Devon's
       board of directors withdrew or changed, in a manner adverse to Ocean, its
       recommendation to its stockholders, or recommended that its stockholders
       vote instead for a competing transaction and (2) Ocean elected to
       exercise its option to require a vote of Devon's stockholders on the
       issuance of Devon common stock pursuant to the merger agreement and
       Devon's stockholders failed to approve the issuance of Devon common stock
       pursuant to the merger agreement at a meeting duly convened for that
       purpose; or

     - Devon or Ocean terminates the merger agreement before Devon's
       stockholders approve the issuance of Devon common stock pursuant to the
       merger agreement and after Devon's board of directors withdraws or
       changes, in a manner adverse to Ocean, its recommendation to its
       stockholders, or recommends that the stockholders vote instead for a
       competing transaction and Ocean does not elect to exercise its option to
       require a vote of Devon's stockholders on the issuance of Devon common
       stock pursuant to the merger agreement.

     However, instead of the $139 million termination fee described above, Devon
has agreed to pay Ocean a $69.5 million termination fee (and to reimburse Ocean
for expenses incurred in connection with the merger agreement up to a maximum of
$10 million) if Devon or Ocean terminates the merger after (1) a competing
transaction involving Devon is publicly announced, but Devon's board of
directors does not withdraw or change, in a manner adverse to Ocean, its
recommendation to stockholders, or recommend that stockholders vote instead for
a competing transaction, and (2) Devon's stockholders fail to approve the
issuance of Devon common stock pursuant to the merger agreement after this
public announcement. If, within 12 months after the merger agreement is
terminated under those circumstances, Devon agrees to merge with a third party
whereby Devon is not the surviving corporation (or, if Devon is the surviving
corporation, Devon stockholders immediately prior to the merger hold less than
50% of the voting stock of Devon immediately after the merger), or a third party
acquires or agrees to acquire at least 50% of Devon's voting stock or assets,
then Devon must pay Ocean an additional $69.5 million termination fee.

     Devon has agreed to reimburse Ocean for expenses incurred in connection
with the merger agreement up to a maximum of $10 million if Devon or Ocean
terminates the merger after Devon's stockholders fail to approve the issuance of
Devon common stock pursuant to the merger agreement even though Devon's board of
directors has not withdrawn or changed, in a manner adverse to Ocean, its
original recommendation to its stockholders, or recommended that its
stockholders vote instead for a competing transaction.

     Collection of Termination Fee.  If either party fails to promptly pay any
termination fee due and, in order to obtain payment, the other party commences a
suit that results in a judgment against the party owing the termination fee, the
party owing the termination fee must pay to the other party its costs and
expenses in connection with the suit, together with interest on the termination
fee from the date payment was required until the date such payment is made at
the annual prime lending rate of JPMorgan Chase Bank in effect on the date the
payment was required to be made, plus 1%.

     Other Expenses.  All costs and expenses incurred in connection with the
merger agreement and related transactions will be paid by the party incurring
them, except that termination fees and expenses will be paid as described above.

                                        72


AMENDMENT; EXTENSION AND WAIVER

     Amendment.  Subject to the next sentence, the merger agreement may be
amended at any time with the consent of Devon's board of directors and Ocean
board of directors. If the merger agreement has been approved by the Devon
stockholders and the Ocean's stockholders, then no amendment can be made that by
law requires the further approval of stockholders without obtaining such further
stockholder approval.

     Extension and Waiver.  At any time prior to the effective time of the
merger, each of Devon and Ocean may, to the extent permitted by law, (1) grant
the other party additional time to perform its obligations under the merger
agreement, (2) waive any inaccuracies in the representations and warranties of
the other party and (3) waive compliance with any agreements or conditions for
the benefit of that party.

            DIRECTORS AND EXECUTIVE OFFICERS OF THE COMBINED COMPANY

DIRECTORS

     Devon's charter divides Devon's board of directors into three classes. At
each annual meeting, Devon stockholders elect the members of one of the three

         DEVON ENERGY CORPORATION 2003 OMNIBUS LONG-TERM INCENTIVE PLAN

     The following is a summary of the material terms of the Devon Energy
Corporation 2003 Omnibus Long-Term Incentive Plan, a copy of which is attached
to this document as Annex E and is incorporated into this document by reference.

     Subject to approval by Devon stockholders, Devon's board of directors has
approved the Devon Energy Corporation 2003 Omnibus Long-Term Incentive Plan,
which we sometimes refer to in this document as the "new long-term incentive
plan" or the "plan." The plan is also conditioned on approval by Devon
stockholders of the issuance of shares of Devon common stock pursuant to the
merger agreement and completion of the merger.

     The new long-term incentive plan authorizes the compensation committee of
Devon's board of directors to grant nonqualified and incentive stock options,
stock appreciation rights, restricted stock awards, performance units and
performance bonuses to selected employees. The plan also authorizes the grant of
nonqualified stock options and restricted stock awards to directors. A total of
12,500,000 shares of Devon common stock have been reserved for issuance pursuant
to the plan.

     In 1997, Devon stockholders approved the Devon Energy Corporation 1997
Stock Option Plan, which reserved a total of two million shares of Devon common
stock to be issued to selected employees. The plan was subsequently amended,
with Devon stockholder approval, to increase the reserved number of shares to 10
million. A total of           shares remain available for grant under the 1997
Plan; however, Devon will cancel all ungranted options under the 1997 Plan upon
approval by Devon stockholders of the new long-term incentive plan and
completion of the merger. Upon completion of the merger, the combined company
will cancel all ungranted equity awards under Ocean's existing long-term
incentive plans.

     Devon's board of directors recommends Devon stockholders vote FOR the
adoption of the Devon Energy Corporation 2003 Omnibus Long-Term Incentive Plan.

PURPOSE AND KEY FEATURES OF THE PLAN

     The new long-term incentive plan is designed to accommodate the increased
employee base of the combined company expected to result from the merger. The
purpose of the plan is to create incentives designed to motivate employees of
the combined company to significantly contribute to the combined company's
growth and profitability. The shares available to be issued under the plan will
enable the combined company to attract and retain experienced employees who, by
their positions, abilities and diligence, are able to make important
contributions to the combined company's success.

     The plan is designed to provide flexibility to meet the needs of the
combined company for three to four years in a changing and competitive
environment while minimizing dilution to stockholders. Devon does not intend to
use all incentive vehicles (options, stock appreciation rights, restricted stock
awards, performance units and performance bonuses) at all times for each
participant, but will selectively grant

                                        74


awards to achieve long-term goals. Awards will be granted in such a way as to
align the interests of participants with those of the combined company's
stockholders. Maximum individual awards as designated by the plan will only be
awarded if individual and company results are such that exceptional stockholder
value is achieved.

     Key features of the new long-term incentive plan include:

     - a prohibition against the repricing of stock options;

     - a prohibition against granting options with an exercise price less than
       the fair market value of Devon common stock on the date of grant;

     - of the 12,500,000 shares reserved for issuance under the plan, only
       2,500,000 may be granted as restricted stock;

     - a maximum eight-year life for any award made under the plan;

     - the following award limits:

      - the maximum number of shares that may be awarded in the form of options
        or stock appreciation rights to an employee in any calendar year is
        400,000;

      - the maximum number of shares that may be awarded in the form of
        restricted stock awards to an employee in any calendar year is 200,000;
        and

      - the maximum performance bonus award payment to an employee is $2,500,000
        in any calendar year; and

     - the compensation committee (composed entirely of outside directors)
       administers the plan and the grant of options and restricted stock to
       Devon's executive officers.

ADMINISTRATION

     The new long-term incentive plan consists of three separate stock plans:

     - Non-executive officer plan: this aspect of the plan is limited to
       participants who are not subject to Section 16 of the Securities Exchange
       Act of 1934 because they are not executive officers of Devon. The
       non-executive officer plan is administered by the compensation committee.
       However, the compensation committee may, to the extent permitted by law,
       delegate authority to the regular award committee to administer the
       non-executive officer plan. Devon's chief executive officer and other
       individuals appointed by the compensation committee will comprise the
       regular award committee. Although the regular award committee may be
       authorized to administer the non-executive officer plan, it can only make
       awards within guidelines set by the compensation committee.

     - Executive officer plan: this aspect of the plan is limited to
       participants who are executive officers of Devon and who, therefore, are
       subject to the reporting requirements of Section 16 of the Securities
       Exchange Act of 1934. The executive officer plan is administered
       exclusively by the compensation committee.

      Except for administration and the category of participants eligible to
      receive awards, the terms of the non-executive officer plan and the
      executive officer plan are identical.

     - Non-employee director plan: this aspect of the plan is limited to
       non-employee directors of Devon and permits only grants of nonqualified
       stock options and restricted stock. Devon's board of directors is
       responsible for selection of non-employee directors for awards and for
       determination of the nature of the award. The compensation committee is
       responsible for the administration of awards granted to non-employee
       directors.

                                        75


ELIGIBILITY FOR PARTICIPATION

     Employees of Devon and its subsidiaries and affiliated entities are
eligible to participate in the new long-term incentive plan. Subject to the
provisions of the plan, the compensation committee has exclusive power in
selecting participants. In addition, non-employee directors are eligible to
receive grants of nonqualified stock options and restricted stock awards under
the plan.

TYPES OF AWARDS

     The new long-term incentive plan provides that any or all of the following
types of awards may be granted:

     - nonqualified stock options and stock options intended to qualify as
       "incentive stock options" under Section 422 of the Internal Revenue Code;

     - stock appreciation rights;

     - restricted stock;

     - performance units; and

     - performance bonuses.

     Stock Options.  The compensation committee may grant awards under the plan
in the form of options to purchase shares of Devon common stock. The
compensation committee will have the authority to determine the terms and
conditions of each option, the number of shares subject to the option, and the
manner and time of the option's exercise. Subject to certain adjustment
provisions, the compensation committee cannot grant options and restricted stock
with respect to more than 400,000 shares of common stock to any participant in
any calendar year. As of           , 2003, the market value of Devon common
stock underlying the options available for issuance under the plan was
$          .

     The exercise price of an option may not be less than the fair market value
of Devon common stock on the date of grant. The fair market value of shares of
common stock subject to options is determined by closing price as reported on
the American Stock Exchange. As of           , 2003, the closing price of Devon
common stock as reported on the American Stock Exchange was $          . A
participant may pay the exercise price of an option in cash, in shares of Devon
common stock or a combination of both; provided that, if the exercise price
(including required withholding taxes) is paid using shares of Devon common
stock, the compensation committee will not allow this act to result in an
adverse accounting charge to Devon. At the present time, the compensation
committee has determined that a participant using Devon common stock to pay the
exercise price of options granted under the plan must have held those shares for
at least six months. The compensation committee may permit the exercise of stock
options through a broker-dealer acting on a participant's behalf if in
accordance with procedures adopted by Devon to ensure that the arrangement will
not constitute a personal loan to the participant. Unless sooner terminated, the
stock options granted under the plan expire eight years from the date of the
grant.

     Stock Appreciation Rights.  A stock appreciation right permits an employee
to receive an amount (in cash, Devon common stock or a combination thereof)
equal to (1) the number of stock appreciation rights exercised by the employee
multiplied by (2)(a) the excess of the fair market value of Devon common stock
on the exercise date over (b) the stock appreciation rights' exercise price.
Stock appreciation rights may or may not be granted in connection with the grant
of an option. The exercise price of stock appreciation rights granted under the
plan will be determined by the compensation committee; provided, however, that
such exercise price cannot be less than the fair market value of a share of
Devon common stock on a date the stock appreciation right is granted. A stock
appreciation right may be exercised in whole or in such installments and at such
times as determined by the compensation committee.

     Restricted Stock Awards.  Shares of restricted stock awarded under the plan
will be subject to the terms, conditions, restrictions and/or limitations, if
any, that the compensation committee deems appropriate, including restrictions
on employment, transferability and continued employment. The

                                        76


compensation committee may also restrict vesting to the attainment of specific
performance targets it establishes that are based upon one or more of the
following criteria:

     - Operational Criteria: reserve additions/replacements, finding and
       development costs, production volume and production costs.

     - Financial Criteria: earnings (net income, EBITDA, earnings per share),
       cash flow, operating income, general and administrative expenses, debt to
       equity ratio, debt to cash flow, debt to EBITDA, EBITDA to interest,
       return on assets, return on equity, return on invested capital, profit
       returns/margins and midstream margins.

     - Stock Performance Criteria: stock price appreciation, total stockholder
       return and relative stock price performance.

If vesting is based upon continued employment, the restricted stock award must
vest over a minimum restriction period of at least three years from the date of
grant. If vesting is based on performance, the restricted stock award must have
a minimum restriction period of at least one year. Subject to certain adjustment
provisions, no more than 200,000 shares of Devon common stock can be awarded to
a participant under the plan as restricted stock awards in any calendar year.

     Performance Units.  The plan permits grants of performance units, which are
rights to receive cash or common stock payments based upon the achievement of
performance goals established by the compensation committee. Such awards are
subject to the fulfillment of conditions that may be established by the
compensation committee, including the achievement of performance targets based
upon the factors described above relating to restricted stock awards.

     Performance Bonus.  The plan permits grants of performance bonuses, which
may be paid in cash, Devon common stock or a combination thereof, as determined
by the compensation committee. The maximum value of performance awards granted
under the plan shall be established by the compensation committee at the time of
the grant. An employee's receipt of such amount will be contingent upon
achievement of performance targets during the performance period established by
the compensation committee. The performance targets will be determined by the
compensation committee based upon the factors described above relating to
restricted stock awards. Following the end of the performance period, the
compensation committee will determine the achievement of the performance targets
for such performance period. Payment may be made within 60 days of such
determination. Any payment made in shares of Devon common stock will be based
upon the fair market value of Devon common stock on the payment date. The
maximum amount of performance bonus payable to a participant in any calendar
year is $2,500,000.

TERMINATION OF EMPLOYMENT

     The compensation committee will determine the treatment of a participant's
award in the event of death, disability, retirement or termination of employment
for an approved reason. If a participant's employment is terminated for any
other reason, all unvested awards will terminate and the compensation committee
will provide in the award agreement the terms of exercise/payment of vested
awards.

AMENDING THE NEW LONG-TERM INCENTIVE PLAN

     Devon's board of directors may amend the new long-term incentive plan at
any time. Devon's board of directors may not, however, without Devon stockholder
approval, (1) adopt any amendment that would increase the maximum number of
shares that may be issued under the plan (except for certain antidilution
adjustments described in the "Automatic Adjustment Features" section of this
document), (2) materially modify the plan's eligibility requirements or (3)
materially increase the benefits provided to participants under the plan.
Amendments to award agreements that would have the effect of repricing
participants' options are prohibited.

                                        77


CHANGE OF CONTROL EVENT

     The compensation committee is authorized to provide in the award agreements
for the acceleration of any unvested portion of any outstanding awards under the
plan upon a change of control event.

NEW PLAN BENEFITS

     To date, no awards have been made under the new long-term incentive plan.

AUTOMATIC ADJUSTMENT FEATURES

     The new long-term incentive plan provides for the automatic adjustment of
the number and kind of shares available under it, and the number and kind of
shares subject to outstanding awards in the event Devon common stock is changed
into or exchanged for a different number or kind of shares of stock or other
securities of Devon or another corporation, or if the number of shares of Devon
common stock is increased through a stock dividend. The plan also provides that
the compensation committee may adjust the number of shares available under the
plan and the number of shares subject to any outstanding awards if, in the
compensation committee's opinion, any other change in the number or kind of
shares of outstanding Devon common stock equitably requires such an adjustment.

U.S. FEDERAL TAX TREATMENT

     Incentive Stock Option Grant/Exercise.  A participant who is granted an
incentive stock option does not realize any taxable income at the time of the
grant or at the time of exercise (except for alternative minimum tax).
Similarly, Devon is not entitled to any deduction at the time of grant or at the
time of exercise. If the participant makes no disposition of the shares acquired
pursuant to an incentive stock option before the later of two years from the
date of grant of such option or one year from the date of exercise of such
shares to the participant, any gain or loss realized on a subsequent disposition
of the shares will be treated as a long-term capital gain or loss. Under such
circumstances, Devon will not be entitled to any deduction for U.S. federal
income tax purposes.

     Non-Qualified Stock Option Grant/Exercise.  A participant who is granted a
non-qualified stock option does not have taxable income at the time of grant.
Taxable income occurs at the time of exercise in an amount equal to the
difference between the exercise price of the shares and the market value of the
shares on the date of exercise. Devon is entitled to a corresponding deduction
for the same amount.

     Restricted Stock Award.  A participant who has been granted an award in the
form of restricted stock will not realize taxable income at the time of the
grant, and Devon will not be entitled to a deduction at the time of the grant,
assuming that the restrictions constitute a substantial risk of forfeiture for
U.S. federal income tax purposes. When such restrictions lapse, the participant
will receive taxable income (and have tax basis in the shares) in an amount
equal to the excess of the fair market value of the shares at such time over the
amount, if any, paid for such shares. Devon will be entitled to a corresponding
deduction. The participant may elect to include the value of his restricted
stock award as income at the time it is granted under Section 83(b) of the Code,
and Devon will take a corresponding income tax deduction at such time.

     Section 162(m) of the Internal Revenue Code.  Section 162(m) of the Code
precludes a public corporation from taking a deduction for annual compensation
in excess of $1 million paid to its chief executive officer or any of its four
other highest-paid officers. However, compensation that qualifies under Section
162(m) of the Code as "performance-based" is specifically exempt from the
deduction limit. Based on Section 162(m) of the Code and the regulations
thereunder, Devon's ability to deduct compensation income generated in
connection with the exercise of stock options or stock appreciation rights
granted under the plan should not be limited by Section 162(m) of the Code.
Further, Devon believes that compensation income generated in connection with
performance awards granted under the plan should not be limited by Section
162(m) of the Code. The plan has been designed to provide flexibility with
respect to whether restricted stock awards or performance bonuses will qualify
as

                                        78


performance-based compensation under Section 162(m) of the Code and, therefore,
be exempt from the deduction limit. If the vesting restrictions relating to such
awards are based solely upon the satisfaction of one of the performance goals
set forth in the plan, then Devon believes that the compensation expense
relating to such an award will be deductible by Devon if the awards become
vested. However, compensation expense deductions relating to such awards will be
subject to the Section 162(m) deduction limitation if such awards become vested
based upon any other criteria set forth in such award (such as the occurrence of
a change in control or vesting based upon continued employment with Devon).

(1) Exercise Price is the closing price of Devon common stock as reported by the
    American Stock Exchange on the date of grant.

                                        80


(2) The Grant Date Present Value is an estimation of the possible future value
    of the option based upon the Black-Scholes Option Pricing Model. The
    following assumptions were used in the model: volatility (a measure of the
    historic variability of a stock price) -- 41.1%; risk-free interest rate
    (the interest paid by zero-coupon U.S. government issues with a remaining
    term equal to the expected life of the options) -- 3.1% per annum; annual
    dividend yield -- 0.4%; and expected life of the options -- five years from
    grant date. The option value estimated using this model does not necessarily
    represent the value to be realized by the named officers.

(3) These options were granted as of December 2, 2002. 20% of such grant was
    immediately vested and exercisable. An additional 20% of such grant becomes
    vested and exercisable on each of the next four anniversary dates of the
    original grant.

(1) The value is based on the aggregate amount of the excess of $45.90 (the
    closing price as reported by the American Stock Exchange for December 31,
    2002) over the relevant exercise price for outstanding options that were
    exercisable and in-the-money at year-end.

(2) The value is based on the excess of the market price over the relevant
    exercise price for the options exercised.

  Employment Agreements

     A small number of Devon's senior executives, including the five individuals
named in the Summary Compensation Table, are entitled to certain additional
compensation under the following events:

     (1) employment with Devon is involuntarily terminated other than for
         "Cause;" or

     (2) employee voluntarily terminates for "Good Reason", as those terms are
         defined in each of the officer's employment agreements.

In either case, the payment due to the officer would be equal to three times the
officer's annual compensation. In addition, the employment agreement provides
for the officer to receive the same basic health and welfare benefits that he or
she would otherwise be entitled to receive if he or she were an employee of
Devon for three years after termination. If the officer is terminated within two
years of a "change in control," he or she is also entitled to an additional
three years of service credit and age in determining eligibility for retiree
medical and supplemental retirement benefits. "Change of control" is defined in
the employment agreements the same as in the retirement plans described below.

  Retirement Plans

     Devon has three employee retirement plans, as follows:

            Basic Plan........   The Basic Plan is a qualified defined benefit
                                 retirement plan which provides benefits based
                                 upon employment service with
                                        81


                                 Devon. Each eligible employee who retires is
                                 entitled to receive annual retirement income,
                                 computed as a percentage of "final average
                                 compensation" (which consists of the average of
                                 the highest three consecutive years' salaries,
                                 wages, and bonuses out of the last ten years),
                                 and credited years of service up to 25 years.
                                 Contributions by employees are neither required
                                 nor permitted under the Basic Plan. Benefits
                                 are computed based on straight-life annuity
                                 amounts and are reduced by Social Security
                                 benefits. Benefits under the Basic Plan are
                                 reduced for certain highly compensated
                                 employees in order to comply with certain
                                 requirements of the Employment Retirement
                                 Income Security Act of 1974 and the Internal
                                 Revenue Code.

                                 The following table sets forth the credited
                                 years of service as of December 31, 2002 under
                                 Devon's Basic Plan for each of the five
                                 individuals named in the Summary Compensation
                                 Table.

            Benefit
            Restoration
Plan..........................   The Benefit Restoration Plan is a non-qualified
                                 retirement benefit plan, the purpose of which
                                 is to restore retirement benefits for certain
                                 selected key management and highly compensated
                                 employees because their annual compensation is
                                 greater than the maximum annual compensation
                                 that can be considered in computing their
                                 benefits under the Basic Plan. An employee must
                                 be selected by Devon's Compensation and Stock
                                 Option Committee in order to be eligible for
                                 participation in the Benefit Restoration Plan.
                                 All other provisions of the Benefit Restoration
                                 Plan mirror those of the Basic Plan. All of the
                                 five individuals named in the Summary
                                 Compensation Table have been selected to
                                 participate in the Benefit Restoration Plan.
                                 The Benefit Restoration Plan has been
                                 informally funded through a rabbi trust
                                 arrangement.

            Supplemental
            Retirement Plan...   The Supplemental Retirement Plan is another
                                 non-qualified retirement plan for a small group
                                 of Devon executives, the purpose of which is to
                                 provide additional retirement benefits for
                                 long-service executives. The plan vests after
                                 10 years of service and provides retirement
                                 income equal to 65% of the executive's final
                                 average compensation, multiplied by a fraction,
                                 the numerator of which is his credited years of
                                 service (not to exceed 20) and the denominator
                                 of which is 20 (or less, if so determined by
                                 the Compensation and Stock Option Committee),
                                 less any offset amounts. Offset amounts are (1)
                                 benefits payable under the Basic Plan, (2)
                                 benefits payable under the Benefit Restoration
                                 Plan, (3) benefits due to the participant under
                                 Social Security, and (4) any benefits paid to
                                 the participant under Devon's long-term
                                 disability plan.

                                        82


                                 In general, benefits will be paid under the
                                 Supplemental Retirement Plan when the
                                 participant retires from Devon. However, in the
                                 event that the executive's employment with
                                 Devon is terminated under conditions that
                                 qualify him or her to a severance benefit under
                                 the Employment Agreement (see above), then the
                                 executive will be 100% vested in his or her
                                 benefit and entitled to receive the actuarial
                                 equivalent of such benefit earned as of the
                                 date of termination of employment. If the
                                 executive is terminated within two years
                                 following a "change of control," his or her
                                 benefit will be paid in a single lump sum
                                 payment. Otherwise, the benefit will be paid
                                 monthly for the life of the executive. "Change
                                 of control" is defined as the date on which one
                                 of the following occurs: (1) an entity or group
                                 acquires 30% or more of Devon's outstanding
                                 voting securities, (2) the incumbent board
                                 ceases to constitute at least a majority of
                                 Devon's board, or (3) a merger, reorganization
                                 or consolidation is consummated, after
                                 stockholder approval, unless (a) substantially
                                 all of the stockholders prior to the
                                 transaction continue to own more than 50% of
                                 the voting power after the transaction, (b) no
                                 person owns 30% or more of the combined voting
                                 securities, and (c) the incumbent board
                                 constitutes at least a majority of the board
                                 after the transaction. The Supplemental
                                 Retirement Plan is also informally funded
                                 through a rabbi trust arrangement.

     The following table shows the estimated aggregate annual retirement
benefits payable under the Basic Plan, the Benefit Restoration Plan and the
Supplemental Retirement Plan to the participants therein, including the five
individuals named in the Summary Compensation Table. The amount presented
assumes a normal retirement in 2002 at age 65.

  Director Compensation

     Non-management directors of Devon receive:

     - an annual retainer of $40,000, payable quarterly;

     - $2,000 for each board meeting attended; directors participating in a
       telephonic meeting receive a fee of $1,000;

     - an additional $3,000 per year for serving as chairmen of a standing
       committee of Devon's board of directors;

     - $2,000 for each committee meeting attended that requires separate travel;
       and

     - $1,000 for each committee meeting that does not require separate travel.

                                        83


     Non-management directors are eligible to receive stock options in addition
to their cash remuneration. Such directors are eligible to receive stock option
grants of up to 3,000 shares immediately after each annual meeting of
stockholders at an exercise price equal to the fair market value of Devon common
stock on that date. Any unexercised options will expire ten years after the date
of grant. The Compensation and Stock Option Committee, which awards options to
non-management directors, may elect to grant awards that are less than the 3,000
shares maximum. However, the Compensation and Stock Option Committee has no
other discretion regarding the award of stock options to non-management
directors. The directors were eligible to receive stock options beginning in
1997. The following table sets forth information concerning options granted to
non-management directors in 2002:

    of the option grant based upon the Black-Scholes Option Pricing Model. The
    following assumptions were used in the model: volatility (a measure of the
    historic variability of a stock price) -- 40.0%; risk-free interest rate
    (the interest paid by zero-coupon U.S. government issues with a remaining
    term equal to the expected life of the options) -- 4.2% per annum; annual
    dividend yield -- 0.4%; and expected life of the options -- five years from
    grant date. The option value estimated using this model does not necessarily
    represent the value to be realized by the named directors.

     Devon's compensation committee is composed of four independent,
non-employee directors, Messrs. Gavrin, Gellert, Hill and Johnson. These
directors have no interlocking relationships as defined by the Securities and

                   MATERIAL FEDERAL INCOME TAX CONSIDERATIONS

     The following discussion summarizes the material U.S. federal income tax
considerations of the merger that are applicable to Ocean stockholders. This
summary is based on the Internal Revenue Code, referred to as the "Code", its
legislative history, applicable U.S. Treasury regulations, judicial authority
and administrative rulings and practice, all as of the date of this document,
all of which are subject to change, possibly with retroactive effect. This
summary does not purport to be a complete discussion of all U.S. federal income
tax consequences of the merger. The discussion below does not address any state,
local or foreign tax consequences of the merger. In addition, this discussion
may not apply, in whole or in part, to particular stockholders, such as
individuals who hold options in respect of Ocean stock or who have acquired
Ocean common stock under a compensatory or other employment-related arrangement,
insurance companies, tax-exempt organizations, financial institutions or
broker-dealers, persons who are neither citizens nor residents of the United
States, traders in securities that elect to mark-to-market, and persons who hold
Ocean stock as part of a hedge, straddle or conversion transaction. The
following discussion assumes that Ocean stock is held as a capital asset at the
effective time of the merger. Ocean stockholders should be aware that the Code
contains limitations on the extent to which a stockholder may deduct capital
losses from ordinary income, and that the federal income tax rate for individual
stockholders on long-term capital gains may be significantly lower than the rate
imposed on ordinary income or short-term capital gains.

     The discussion under this "Material Federal Income Tax Considerations"
section of this document regarding (1) the tax consequences of the merger to the
corporate parties to the reorganization is the opinion of Mayer, Brown, Rowe &
Maw (counsel to Devon) and (2) the tax consequences of the merger to Ocean and
Ocean stockholders is the opinion of Vinson & Elkins L.L.P. (counsel to Ocean),
in each case subject to the limitations and qualifications referenced in the
discussion.

     Ocean stockholders are urged to consult their tax advisors as to the
particular tax consequences of the merger to them, including the applicability
and effect of any U.S. federal, state, local or foreign laws, and the effect of
possible changes in applicable tax laws.

GENERAL

     It is a condition to closing of the merger that (1) Devon receive an
opinion of its counsel, Mayer, Brown, Rowe & Maw, to the effect that (a) the
merger will be treated for federal income tax purposes as a reorganization
within the meaning of section 368(a) of the Code, and (b) no gain or loss will
be recognized by any corporation which is a party to the reorganization, and (2)
Ocean receive an opinion of its counsel, Vinson & Elkins L.L.P., to the effect
that (a) the merger will be treated for federal income tax purposes as a
reorganization within the meaning of section 368(a) of the Code, and (b) no gain
or loss will be recognized by Ocean or Ocean stockholders to the extent that
they receive Devon common stock in exchange for shares of Ocean common stock in
the merger. The opinions of counsel will assume that (1) the statements and
facts concerning the merger set forth in the merger agreement and described in
this document, other than in this "Material Federal Income Tax Considerations"
section of this document, are true, correct and complete, and (2) the merger
will be consummated in the manner contemplated by, and in accordance with the
terms set forth in, the merger agreement and described in this document. In
addition, the tax opinions will be based on factual representations made by
Devon and Ocean. If the tax opinions to be delivered as of the closing are
materially different from the opinions respecting the federal income tax
considerations expressed in this "Material Federal Income Tax Considerations"
section of this document, Devon and Ocean would not effect the merger without
recirculating this document after revising this discussion appropriately and
resoliciting the approvals of their stockholders.

     Neither Devon nor Ocean has requested nor will request an advance ruling
from the Internal Revenue Service as to the tax consequences of the merger, and
there can be no assurance that the Internal Revenue Service will agree with the
conclusions in the above-described opinions or in the discussion below. The

                                        85


discussion below assumes that the merger qualifies as a reorganization within
the meaning of section 368(a) of the Code.

TAX TREATMENT OF CORPORATE PARTIES TO THE REORGANIZATION AND OF OCEAN COMMON
STOCKHOLDERS

     Based on, and subject to the limitations in, the foregoing:

     No corporate party to the merger, including Ocean, will recognize gain or
loss as a result of the merger.

     Except with respect to any cash received instead of fractional shares of
Devon common stock, an Ocean common stockholder will not recognize any gain or
loss as a result of the receipt of shares of Devon common stock in the merger.
An Ocean common stockholder's aggregate tax basis for the shares of Devon common
stock received in the merger, including any fractional share interest for which
cash is received, will equal the stockholder's aggregate tax basis in shares of
Ocean common stock held immediately before the effective time of the merger. An
Ocean common stockholder's holding period for the shares of Devon common stock
received in the merger, including any fractional share interest for which cash
is received, will include the period during which the shares of Ocean common
stock were held.

     An Ocean common stockholder who receives cash instead of a fractional share
of Devon common stock in the merger will generally recognize capital gain or
loss in an amount equal to the difference between the amount of cash received
and the stockholder's adjusted tax basis allocable to such fractional share.

TAX TREATMENT OF OCEAN CONVERTIBLE PREFERRED STOCKHOLDERS

     Based on, and subject to the limitations in, the foregoing:

     The federal income tax consequences of the merger to Ocean convertible
preferred stockholders are not clear. Under analogous legal authorities, the
automatic substitution, at the effective time of the merger, of Devon common
stock for Ocean common stock under the terms of the conversion rights provision
of the Ocean convertible preferred stock would not constitute an issuance of new
preferred stock pursuant to the merger. Under this approach, no gain or loss
would be recognized by an Ocean convertible preferred stockholder as a result of
the merger. A subsequent conversion of the Ocean convertible preferred stock
may, however, be a taxable transaction on which gain or loss would be recognized
based upon the difference in the value of the Devon common stock received in the
conversion and the stockholder's basis in the converted Ocean convertible
preferred stock.

     No assurance can be given that the Internal Revenue Service will not
challenge this nonrecognition approach to the merger or that such a challenge
will not be successful. Specifically, the Internal Revenue Service could assert
that the automatic substitution, at the effective time of the merger, of Devon
common stock for Ocean common stock under the terms of the conversion provision
of Ocean convertible preferred stock constitutes a taxable exchange. In such an
exchange, an Ocean convertible preferred stockholder would recognize gain or
loss equal to the difference between the value of the Ocean convertible
preferred stock immediately after the effective time of the merger and the Ocean
convertible preferred stockholder's basis in the Ocean convertible preferred
stock immediately prior to the effective time of the merger.

     An Ocean convertible preferred stockholder that exercises the conversion
option prior to the effective time of the merger will not recognize gain or loss
upon the receipt of Ocean common stock pursuant to the conversion, except that
the portion of such Ocean common stock which is attributable to accrued unpaid
dividends, if any, on the convertible preferred stock will be treated as a
taxable dividend. Except with respect to any cash received instead of fractional
shares of Devon common stock, such convertible preferred stockholder will not
recognize gain or loss as a result of the receipt of shares of Devon common
stock in exchange for its Ocean common stock in the merger.

                                        86


     The merger will be a taxable event for an Ocean convertible preferred
stockholder that perfects its appraisal rights under Delaware law and receives
cash in exchange for the stockholder's convertible preferred shares.

BACKUP WITHHOLDING; INFORMATION REPORTING

     The cash payments due to a stockholder on the exchange of stock in the
merger, other than certain exempt persons or entities, will be subject to
"backup withholding" for U.S. federal income tax purposes unless certain
requirements are met. Devon or a third-party paying agent, as the case may be,
must withhold approximately 30% of the cash payments to a stockholder, unless
the stockholder (1) is a corporation or comes within certain other exempt
categories and, when required, demonstrates this fact, or (2) provides Devon or
the third-party paying agent, as the case may be, with the stockholder's
taxpayer identification number and completes a form in which the stockholder
certifies that the stockholder has not been notified by the Internal Revenue
Service that the stockholder is subject to backup withholding as a result of a
failure to report interest and dividends. The taxpayer identification number of
an individual is his or her Social Security number. An amount paid as backup
withholding will be credited against the stockholder's U.S. federal income tax
liability. Stockholders must also comply with the information reporting
requirements of the Treasury regulations under the tax-free reorganization
provisions of the Code. Appropriate documentation for the foregoing purposes
will be provided to Ocean common stockholders by the exchange agent.

                                        87


            COMPARISON OF THE RIGHTS OF OCEAN AND DEVON STOCKHOLDERS

     The rights of Ocean stockholders are currently governed by Delaware law,
Ocean's certificate of incorporation, as amended, Ocean's bylaws and Ocean's
stockholder rights plan. Upon completion of the merger, Ocean stockholders will
become Devon stockholders and their rights as Devon stockholders will be
governed by Delaware law, Devon's restated certificate of incorporation, as
amended, Devon's amended and restated bylaws and Devon's stockholder rights
plan.

     The following describes the material differences between the rights of
Ocean stockholders and the rights of Devon stockholders. It is not a complete
summary of the provisions affecting, and the differences between, the rights of
Ocean stockholders and Devon stockholders. The summary is qualified in its
entirety by reference to the Delaware General Corporation Law; Ocean's
certificate of incorporation, as amended; Ocean's bylaws; Ocean's stockholder
rights plan; Devon's restated certificate of incorporation, as amended; Devon's
amended and restated bylaws; and Devon's stockholder rights plan. In this
summary, we refer to Devon's restated certificate of incorporation, as amended,
as Devon's charter, and to Ocean's certificate of incorporation, as amended, as
Ocean's charter.

FORWARD-LOOKING STATEMENTS

     Devon and Ocean have made forward-looking statements in this document and
in the documents incorporated by reference into this document, which are subject
to risks and uncertainties. These statements are based on the beliefs and
assumptions of our managements and on the information currently available to
them.

     Statements and calculations concerning oil, natural gas and NGL reserves
and their present value also are forward-looking statements in that they reflect
the determination, based on estimates and assumptions, that oil, natural gas and
NGL reserves may be profitably exploited in the future. When used or referred to
in this document or the documents incorporated by reference into this document,
these forward-looking statements may be preceded by, followed by or otherwise
include the words "believes," "expects," "anticipates," "intends," "plans,"
"estimates," "projects" or similar expressions, or statements that certain
events or conditions "will" or "may" occur. Forward-looking statements in this
document also include:

     - statements regarding Devon's expectation that the merger will be dilutive
       to its reserves per share, production per share and earnings per share
       and Oceans' expectation that the merger will be accretive to cash flows
       per share for Ocean stockholders;

     - statements relating to the cost savings that Devon and Ocean anticipate
       will result from the merger;

     - statements regarding other perceived benefits expected to result from the
       merger;

     - statements regarding the number and location of undrilled well locations
       and planned wells;

     - statements relating to future reserve replacement;

     - statements with respect to various actions to be taken or requirements to
       be met in connection with completing the merger or integrating Devon and
       Ocean; and

     - statements relating to revenue, income and operations of the combined
       company after the merger is completed.

     These forward-looking statements are subject to a number of factors and
uncertainties that could cause actual results to differ materially from those
described in the forward-looking statements. The following factors, among
others, including those discussed in the "Risk Factors" section of this
document, could cause actual results to differ materially from those described
in the forward-looking statements:

     - expected cost savings from the merger may not be fully realized;

     - revenue of the combined company following the merger may be lower than
       expected;

     - assumptions about energy markets, commodity prices, production levels,
       reserve levels, operating results, competitive conditions, technology,
       currency exchange rates, the weather, inflation, the availability of
       goods and services, drilling risks, future processing volumes, pipeline
       throughput, the availability of capital resources and capital expenditure
       obligations may prove to be incorrect;

     - changes may occur in the supply and demand for oil, natural gas, NGLs and
       the other products or services provided or consumed by our companies;

     - changes may occur in the price of oil, natural gas, NGLs and the other
       products or services provided or consumed by our companies;

     - costs or difficulties related to obtaining regulatory approvals for
       completing the merger and, following the merger, to the integration of
       the businesses of Devon and Ocean, may be greater than expected;

     - general economic conditions, either internationally or nationally or in
       the jurisdictions in which Devon or Ocean is doing business, may be less
       favorable than expected;

     - legislative or regulatory changes, including changes in environmental
       regulation, may adversely affect the businesses in which Devon and Ocean
       are engaged;
                                        96


     - there may be environmental risks and liability under federal, state and
       foreign environmental laws and regulations; and

     - changes may occur in the securities or capital markets.

     Except for its ongoing obligations to disclose material information as
required by the federal securities laws, neither Devon nor Ocean has any
intention or obligation to update these forward-looking statements after it
distributes this document.

                        COMMONLY USED OIL AND GAS TERMS

     The following are abbreviations and definitions of terms commonly used in
the oil and gas industry and in this document:

     "Bbl" means one stock tank barrel, or 42 U.S. gallons liquid volume of oil
or NGLs.

     "Bcf" means one billion cubic feet.

     "Boe" means barrel of oil equivalent, determined by using the ratio of one
Bbl of oil or NGLs to six Mcf of natural gas.

     "gross acres" or "gross wells" means the total acres or number of wells in
which a working interest is owned.

     "MBbls" means one thousand Bbls.

     "MBoe" means one thousand Boe.

     "Mcf" means one thousand cubic feet.

     "Mcfe" means one thousand cubic feet equivalent of natural gas, determined
using the ratio of six Mcf of natural gas to one Bbl of oil or NGLs.

     "MMBbls" means one million Bbls.

     "MMBoe" means one million Boe.

     "MMcf" means one million cubic feet.

     "net acres" or "net wells" means the sum of the fractional working
interests owned in gross acres or gross wells.

     "NGL" or "NGLs" means natural gas liquids.

     "oil" includes crude oil and condensate.

     "proved reserves" are the estimated quantities of crude oil, natural gas
and NGLs that geological and engineering data demonstrate with reasonable
certainty to be recoverable in future years from known reservoirs under existing
economic and operating conditions (i.e., prices and costs as of the date the
estimate is made). Prices include consideration of changes in existing prices
provided only by contractual arrangements, but not on escalations based on
future conditions.

     (1) Reservoirs are considered proved if economic producibility is supported
by either actual production or a conclusive formation test. The area of a
reservoir considered proved includes:

          (A) that portion delineated by drilling and defined by gas-oil and/or
     oil-water contacts, if any; and

          (B) the immediately adjoining portions not yet drilled, but which can
     be reasonably judged as economically productive on the basis of available
     geological and engineering data. In the absence of information on fluid
     contacts, the lowest known structural occurrence of hydrocarbons controls
     the lower proved limit of the reservoir.

     (2) Reserves that can be produced economically through application of
improved recovery techniques (such as fluid injection) are included in the
"proved" classification when successful testing by a pilot project, or the
operation of an installed program in the reservoir, provides support for the
engineering analysis on which the project or program was based.

     (3) Estimates of proved reserves do not include the following:

          (A) oil that may become available from known reservoirs but is
     classified separately as "indicated additional reserves";

                                        98


          (B) crude oil, natural gas and NGLs, the recovery of which is subject
     to reasonable doubt because of uncertainty as to geology, reservoir
     characteristics or economic factors;

          (C) crude oil, natural gas and NGLs, that may occur in undrilled
     prospects; and

          (D) crude oil, natural gas and NGLs, that may be recovered from oil
     shales, coal, gilsonite and other such sources.

     "Tcfe" means one trillion cubic feet equivalent of natural gas, determined
by using the ratio of six Mcf of natural gas to one Bbl of oil or NGLs.

                                        99


               UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

     The following unaudited pro forma combined financial information shows the
pro forma effect of the merger. The unaudited pro forma combined financial
information includes a statement of operations for the year ended December 31,
2002, which assumes the merger occurred on January 1, 2002. The unaudited pro
forma combined financial information also includes a balance sheet as of
December 31, 2002, which assumes the merger occurred on that date.

     The unaudited pro forma combined financial information has been prepared to
assist in your analysis of the financial effects of the merger. It is based on
the historical financial statements of Devon and Ocean and should be read in
conjunction with those historical financial statements and related notes, which
are incorporated by reference into this document.

     The pro forma information is based on the estimates and assumptions set
forth in the notes to such information. It is preliminary and is being furnished
solely for information purposes. The pro forma information does not purport to
represent what the financial position and the results of operations of the
combined company would have actually been had the merger in fact occurred on the
dates indicated, nor is it necessarily indicative of the results of operations
or financial position that may occur in the future.

     The information was prepared based on the following:

     - Both Devon and Ocean use the full cost method of accounting for their oil
       and gas producing activities.

     - Devon acquired all the outstanding common shares of Mitchell Energy &
       Development Corp. on January 24, 2002. Devon's operating results for 2002
       included in the unaudited pro forma statement of operations assume that
       the Mitchell acquisition occurred on January 1, 2002.

     - We have not reflected as an adjustment to the historical data annual cost
       savings of at least $50 million that Devon and Ocean expect to result
       from the merger.

     - Devon recognized net earnings from discontinued operations in 2002 of $45
       million. This gain is not included in the summary unaudited pro forma
       combined statement of operations.

     No pro forma adjustments have been made with respect to the following
unusual items. These items are reflected in the historical results of Devon and
Ocean, as applicable, and should be considered in reading the pro forma results:

     - In the second quarter of 2002, Devon recognized a $651 million ($371
       million after tax) reduction to the carrying value of its Canadian oil
       and gas properties pursuant to the full cost accounting ceiling rules.

     - In the third quarter of 2002, Ocean announced that it would discontinue
       current exploratory activities in Pakistan and on Block 10 offshore
       Angola. As a result, Ocean recognized an impairment in the amount of $76
       million ($50 million after tax).

     - In the fourth quarter of 2002, Devon recognized a $205 million ($128
       million after tax) expense related to the impairment of the value of 7.1
       million shares of ChevronTexaco Corporation common stock owned by Devon.
       The impairment was related to Devon's determination that the decline in
       the value of the ChevronTexaco common stock was other than temporary, as
       such term is defined by accounting rules.

          NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION
                               DECEMBER 31, 2002

1.  BASIS OF PRESENTATION

     The accompanying unaudited pro forma balance sheet and statement of
operations present the pro forma effects of the merger. The unaudited pro forma
balance sheet is presented as though the merger occurred on December 31, 2002.
The unaudited pro forma statement of operations is presented as though the
merger occurred on January 1, 2002.

2.  METHOD OF ACCOUNTING FOR THE MERGER

     Devon will account for the merger using the purchase method of accounting
for business combinations. Under that method of accounting, one of the combining
companies -- in this case, Devon -- is deemed to be the acquiror for accounting
purposes based on a number of factors determined in accordance with generally
accepted accounting principles.

     The purchase method of accounting requires that Ocean's assets and
liabilities assumed by Devon be revalued and recorded at their estimated "fair
values." In the merger, Devon will issue 0.414 of a share of Devon common stock
for each outstanding share of Ocean common stock. On a pro forma basis, assuming
that the merger had occurred on December 31, 2002, this would have resulted in
Devon issuing about 73 million shares of its common stock to Ocean stockholders,
excluding (1) shares of Devon common stock that would have been issued had all
of the Ocean stock options outstanding on that date been exercised on that date,
(2) shares of Devon common stock that would have been issued had all of the
shares of Ocean convertible preferred stock outstanding on that date been
converted into shares of Ocean common stock on that date, and (3) 43,884 shares
of Devon common stock that would have been issued had Ocean issued prior to that
date all of the 106,000 shares of Ocean common stock that it is permitted to
issue between February 23, 2003 and the date on which the merger is completed
pursuant to the terms of the merger agreement.

     The purchase price of Ocean's net assets will be based on the total value
of the Devon common stock issued to the Ocean stockholders. The value of the
Devon common stock issued is based on the average closing price of Devon's
common stock for a period of two days before and after announcement of the
merger. This average closing price equaled $48.05 per share.

3.  PRO FORMA ADJUSTMENTS RELATED TO THE MERGER

     The unaudited pro forma balance sheet includes the following adjustments:

     (a) This entry adjusts the historical book values of Ocean's assets and
liabilities to their estimated fair values as of December 31, 2002. The
calculation of the total purchase price and the preliminary allocation of this
price to assets and liabilities are shown below.

     The total purchase price includes the value of the Devon common stock to be
issued to Ocean stockholders in the merger. The total purchase price also
includes:

     - $100 million of estimated merger costs. These costs include investment
       banking expenses, severance, legal and accounting fees, printing expenses
       and other merger-related costs. These costs have been added to current
       liabilities in the unaudited pro forma balance sheet.

     - $125 million of Devon employee stock options to be issued in exchange for
       existing Ocean employee stock options. The value of these options is
       added to additional paid-in capital in the unaudited pro forma balance
       sheet.

     - $73 million for the fair value of Ocean's convertible preferred stock. On
       a pro forma basis as of December 31, 2002, this preferred stock, which
       has an annual dividend of 6.5% on a $50 million face value, would be
       convertible into approximately 1.4 million shares of Devon common stock.
       Because this preferred stock will be part of the equity of a subsidiary
       of the combined company, the fair value is included outside of the
       combined company's pro forma stockholders' equity.

     The purchase price allocation is preliminary and is subject to change due
to several factors, including: (1) changes in the fair values of Ocean's assets
and liabilities as of the effective time of the merger; (2) the actual merger
costs incurred; (3) the number of Ocean shares and stock options outstanding as
of the effective time of the merger; and (4) changes in Devon's valuation
estimates that may be made between now and the effective time of the merger.
These changes will not be known until after the effective time of the merger.
However, Devon does not believe that the final purchase price allocation will
differ materially from the estimated allocation presented herein.

     (b) This adjustment includes an $18 million reduction of common stock, a
$1.6 billion reduction of additional paid-in capital, a $3 million reduction of
retained earnings, a $30 million reduction of accumulated other comprehensive
loss, a $35 million reduction of treasury stock and a $15 million reduction of
other stockholders' equity. These adjustments eliminate the historical book
value of Ocean's stockholders' equity.

                                       F-5

   NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION -- (CONTINUED)

     The unaudited pro forma statement of operations includes the following
adjustments:

     (c) This adjustment revises Ocean's historical depreciation, depletion and
amortization expense to reflect the adjustment of Ocean's assets from historical
book value to fair value. For the combined companies' oil and gas producing
properties, pro forma depreciation, depletion and amortization expense was
calculated using the equivalent units-of-production method. Ocean's proved oil,
gas and NGLs reserves, divided by its annualized production for 2002, yields an
estimated reserve life of approximately nine years.

     (d) This adjustment reduces interest expense, net of capitalized interest,
for the effect of valuing Ocean's assets and long-term debt at estimated fair
value.

     (e) This adjustment reclassifies the approximately $3 million of Ocean's
preferred stock dividends. After the merger, this preferred stock will be part
of the equity of a subsidiary of the combined company. Therefore, dividends paid
on the preferred stock will be included as an expense of the combined company,
similar to interest expense, as opposed to a direct reduction of stockholders'
equity.

     (f) This adjustment records the income tax impact of the depreciation,
depletion, amortization and interest expense pro forma adjustments at an
effective tax rate of approximately 38%.

4.  COMMON SHARES OUTSTANDING

     Net earnings per average common share outstanding for the year ended
December 31, 2002 have been calculated based on the pro forma weighted average
number of shares outstanding as follows:



                                                              (IN MILLIONS)

     The above potentially issuable shares are excluded from the diluted shares
outstanding because their inclusion would be anti-dilutive.

   NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION -- (CONTINUED)

     Pro forma shares of Devon common stock outstanding at December 31, 2002,
assuming the merger occurred at that date, are as follows:



                                                              (IN MILLIONS)

Pro forma Devon common shares outstanding...................       230
                                                                   ===


5.  GOODWILL

     The preliminary allocation of the purchase price includes approximately
$1.3 billion of goodwill. Approximately $721 million of this total is related to
deferred income tax liabilities to be recorded due to the non-taxable nature of
the merger.

     In July 2001, the Financial Accounting Standards Board issued Statement No.
141, Business Combinations, and Statement No. 142, Goodwill and Other Intangible
Assets. As a result of these two pronouncements, goodwill recorded in connection
with business combinations completed after June 30, 2001 is not amortized but,
instead, is tested for impairment at least annually. Accordingly, the
accompanying unaudited pro forma statement of operations includes no
amortization of the goodwill to be recorded in the merger.

     As indicated in Note 3, the allocation of the purchase price presented
therein is preliminary. At the effective time of the merger, or shortly
thereafter, Devon will finalize the purchase price allocation. Prior to that
time, Devon may determine that there are intangible assets acquired in the
merger separate and apart from goodwill. To the extent that such intangible
assets, if any, have definite useful lives, the value assigned to those
intangible assets would be amortized over such lives. Although the amount
allocated to such intangible assets, if any, will not be known until the
effective time of the merger, Devon does not believe that any such value, or the
related amortization, would have a material effect on the unaudited pro forma
financial information presented herein.

6.  DEVON PRO FORMA RESULTS OF OPERATIONS

     Devon's pro forma results of operations included in the accompanying
unaudited pro forma statement of operations include the effect of Devon's
acquisition of Mitchell, which was completed on January 24, 2002. Devon's actual
results for the year 2002 and its pro forma results assuming the Mitchell
acquisition occurred on January 1, 2002 are not materially different.
Information concerning the pro forma effects on Devon's 2002 results from the
Mitchell acquisition are included in the notes to Devon's consolidated financial
statements that are incorporated by reference into this document.

7.  OCEAN HISTORICAL AND RECLASSIFIED BALANCES

     Devon and Ocean present certain revenues and expenses differently in their
respective consolidated financial statements. To make the unaudited pro forma
financial information consistent, we have reclassified certain of Ocean's 2002
reported balances of revenues and expenses to conform presentation.

8.  ADOPTION OF NEW ACCOUNTING STANDARD

     In June 2001, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 143, Accounting for Asset Retirement
Obligations. SFAS No. 143 requires liability recognition for retirement
obligations associated with tangible long-lived assets, such as producing well
sites, offshore production platforms, and natural gas processing plants. The
obligations included within the scope of SFAS No. 143 are those for which a
company faces a legal obligation for settlement. The initial measurement of the
asset retirement obligation is to be the discounted present fair value, defined
as the price that an entity would have to pay a willing third party of
comparable credit standing to assume the liability in a current transaction
other than in a forced or liquidation sale.

     The asset retirement cost equal to the discounted fair value of the
retirement obligation is to be capitalized as part of the cost of the related
long-lived asset and allocated to expense using a systematic and rational
method.

                                       F-8

   NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION -- (CONTINUED)

     Devon will adopt SFAS No. 143 effective January 1, 2003 using a cumulative
effect approach to recognize transition amounts for asset retirement
obligations, asset retirement costs and accumulated depreciation.

     Devon and Ocean previously estimated costs of dismantlement, removal, site
reclamation, and other similar activities in the total costs that are subject to
depreciation, depletion, and amortization. However, they did not record a
separate asset or liability for such amounts.

     On a pro forma basis, assuming the merger was completed on January 1, 2003,
the pro forma balance sheet of the combined company would include an increase to
stockholders' equity of between $23 million and $43 million, an increase to net
property and equipment of between $556 million and $636 million, the
establishment of an asset retirement obligation liability of between $519
million and $569 million, and an increase to deferred tax liabilities of between
$14 million and $24 million.

     Future cash inflows are computed by applying year-end prices to the
year-end quantities of proved reserves, except in those instances where fixed
and determinable price changes are provided by contractual arrangements in
existence at year-end. These year-end prices are adjusted for transportation and
other charges and for geographic differentials. The December 31, 2002 NYMEX oil
price and Henry Hub gas price, upon which the combined company's actual net
prices were based before relevant adjustments, were $31.20 per barrel and $4.74
per Mcf, respectively.

     THIS AGREEMENT AND PLAN OF MERGER (this "Agreement"), dated as of February
23, 2003, is among Devon Energy Corporation, a Delaware corporation ("Parent"),
Devon NewCo Corporation, a Delaware corporation and a direct and wholly owned
subsidiary of Parent ("Merger Sub"), and Ocean Energy, Inc., a Delaware
corporation (the "Company").

                                    RECITALS

     WHEREAS, the respective Boards of Directors of each of Parent, Merger Sub
and the Company have determined that the merger of Merger Sub with and into the
Company (the "Merger"), in the manner contemplated herein, is advisable and in
the best interests of their respective corporations and stockholders, and, by
resolutions duly adopted, have approved this Agreement;

     WHEREAS, for federal income tax purposes, it is intended that the Merger
qualify as a reorganization within the meaning of section 368(a) of the Internal
Revenue Code of 1986, as amended, and the rules and regulations promulgated
thereunder (the "Code"); and

     WHEREAS, the Company, Parent and Merger Sub desire to make certain
representations, warranties, covenants and agreements in connection with this
Agreement.

     NOW, THEREFORE, in consideration of the foregoing, and of the
representations, warranties, covenants and agreements contained herein, the
parties hereto hereby agree as follows:

                                   ARTICLE 1

                                   THE MERGER

     SECTION 1.1  The Merger.  Subject to the terms and conditions of this
Agreement, at the Effective Time (as defined in Section 1.3), Merger Sub shall
be merged with and into the Company in accordance with this Agreement, and the
separate corporate existence of Merger Sub shall thereupon cease. The Company
(sometimes hereinafter referred to as the "Surviving Corporation") shall be the
surviving corporation in the Merger and shall be a wholly owned subsidiary of
Parent. The Merger shall have the effects specified in the Delaware General
Corporation Law ("DGCL"). At the election of Parent, any direct wholly owned
subsidiary of Parent may be substituted for Merger Sub as a constituent
corporation in the Merger at any time prior to the meetings of each of the
Company's and the Parent's stockholders contemplated by Section 5.4 so long as
such substitution does not delay either such meeting.

     SECTION 1.2  The Closing.  Subject to the terms and conditions of this
Agreement, the closing of the Merger (the "Closing") shall take place (a) at the
offices of Mayer, Brown, Rowe & Maw, 700 Louisiana Street, Houston, Texas 77002,
at 9:00 a.m., local time, on the first business day immediately following the
day on which the last to be fulfilled or waived of the conditions set forth in
Article 6 (other than those conditions that by their nature are to be satisfied
at the Closing, but subject to fulfillment or waiver of those conditions) shall
be fulfilled or waived in accordance herewith or (b) at such other time, date or
place as Parent and the Company may agree in writing. The date on which the
Closing occurs is hereinafter referred to as the "Closing Date."

     SECTION 1.3  Effective Time.  If all the conditions to the Merger set forth
in Article 6 shall have been fulfilled or waived in accordance herewith and this
Agreement shall not have been terminated as provided in Article 7, on the
Closing Date, a certificate of merger (the "Certificate of Merger") meeting the
requirements of Section 251 of the DGCL shall be properly executed and filed
with the Secretary of State of the State of Delaware. The Merger shall become
effective upon the filing of the Certificate of Merger with the Secretary of
State of the State of Delaware in accordance with the DGCL, or at such later
time that the parties hereto shall have agreed upon and designated in such
filing as the effective time of the Merger (the "Effective Time").

     SECTION 1.4  Certificate of Incorporation.  At the Effective Time, the
certificate of incorporation of the Company shall be amended to read as set
forth in Exhibit A attached hereto, and as so amended shall

                                       A-4


be the certificate of incorporation of the Surviving Corporation, until duly
amended in accordance with applicable law.

     SECTION 1.5  Bylaws.  The bylaws of Merger Sub in effect immediately prior
to the Effective Time shall be the bylaws of the Surviving Corporation, until
duly amended in accordance with applicable law.

     SECTION 1.6  Board of Directors of Surviving Corporation.  The Board of
Directors of the Surviving Corporation shall consist of the Board of Directors
of Merger Sub, as it existed immediately prior to the Effective Time, until
changed in accordance with applicable law. Each of the members of the Board of
Directors of the Company shall tender his or her resignation as a director of
the Company, to be effective at the Effective Time.

     SECTION 1.7  Board of Directors of Parent.  At the Effective Time, the
Board of Directors of Parent shall consist of such number of persons as may be
determined by Parent. If the Board of Directors of Parent is to consist of 13
directors at the Effective Time, Parent shall, except as provided otherwise in
this Section 1.7, cause the four persons from the Company's Board of Directors
designated in writing by the Company no later than March 10, 2003 to be
appointed to the Board of Directors of Parent at the Effective Time; provided,
however, that if the Board of Directors of Parent will consist of more or less
than 13 directors immediately after the Effective Time, then Parent shall cause
a number of persons designated in writing by the Company (and from the Company's
Board of Directors as existing on the date hereof) equal to four-thirteenths of
the total number of directors (rounded upward to the nearest whole number) to be
included on the Board of Directors of Parent at the Effective Time. The persons
designated by the Company for inclusion on the Board of Directors of Parent
pursuant to this Section 1.7 are referred to herein as the "Company Designees".
Parent shall notify the Company if the number of directors constituting the
Board of Directors at the Effective Time will be more or less than 13 directors.
If the number of directors to be designated by the Company pursuant to this
Section 1.7 is less than four, then Parent shall cause the Company Designees to
be appointed in the order designated by the Company. If the number of directors
to be designated by the Company pursuant to this Section 1.7 is greater than
four directors, the Company shall provide Parent with written notice of the
additional individuals designated to serve as Company Designees. The Company
shall provide Parent the information concerning each Company Designee that would
be required to be included in a proxy statement under Regulation 14A of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"). If Parent
determines in its sole discretion that any Company Designee is unacceptable to
Parent, Parent and the Company will agree upon a substitute Company Designee
from the Company's Board of Directors as soon as practicable and in any event
prior to the mailing of the Proxy Statement/Prospectus (as defined in Section
5.8). The Company Designees shall be allocated as evenly as possible among the
different classes of Parent directors, but otherwise at Parent's discretion;
provided, however, that, in the event there are four or more Company Designees
and except as provided in the following sentence, the term of one Company
Designee may expire at Parent's annual meeting held in 2004 and the terms of the
remaining Company Designees shall expire at Parent's annual meeting held in 2005
and 2006. If the Effective Time occurs prior to Parent's annual meeting held in
2003, the Company Designee(s) who would have been appointed to a term expiring
at Parent's annual meeting held in 2006 under the immediately preceding sentence
shall instead be appointed to a term expiring at Parent's annual meeting held in
2003 and shall be nominated for election at that meeting to a term expiring at
Parent's annual meeting held in 2006.

     SECTION 1.8  Executive Officers of Parent.  At the Effective Time, the
Executive Officers of Parent shall include Larry J. Nichols, who shall serve as
Chairman of the Board and Chief Executive Officer, and James T. Hackett, who
shall serve as President and Chief Operating Officer (in each case assuming he
is willing and able to serve).

                                       A-5


                                   ARTICLE 2

                          CONVERSION OF COMPANY SHARES

     SECTION 2.1  Effect on Capital Stock.  At the Effective Time, the Merger
shall have the following effects on the capital stock of the Company and Merger
Sub, without any action on the part of the holder of any capital stock of the
Company or Merger Sub:

          (a) Conversion of the Company Common Shares.  Subject to the
     provisions of this Section 2.1, each share of Common Stock, $0.10 par value
     per share, of the Company (each a "Company Common Share" and collectively
     the "Company Common Shares") issued and outstanding immediately prior to
     the Effective Time (but not including any Company Common Shares that are
     owned (i) by Parent, Merger Sub or any other direct or indirect Subsidiary
     of Parent or (ii) by the Company or any direct or indirect Subsidiary of
     the Company (the "Excluded Company Shares")) shall, by virtue of the Merger
     and without any action on the part of the holder thereof, be converted into
     0.414 of a share (the "Exchange Ratio") of Parent Common Stock (the "Merger
     Consideration"). "Parent Common Stock" shall mean the common stock, par
     value $0.10 per share, of Parent.

          (b) Company Preferred Shares.  Each share of Series B Convertible
     Preferred Stock, $1.00 par value per share, of the Company (each, a
     "Company Preferred Share," and collectively the "Company Preferred Shares;"
     and, together, the Company Common Shares and the Company Preferred Shares
     are collectively referred to herein as the "Company Shares"), other than
     Appraisal Shares (as defined in Section 2.3), issued and outstanding
     immediately prior to the Effective Time shall remain outstanding as one
     share of Series B Convertible Preferred Stock, par value $1.00 per share,
     of the Surviving Corporation. From and after the Effective Time, all shares
     of the Series B Convertible Preferred Stock of the Surviving Corporation
     then outstanding shall be convertible into Parent Common Stock instead of
     Company Common Shares in accordance with the terms of the certificate of
     designations governing such series, giving effect to the Exchange Ratio.

          (c) Cancellation of Excluded Company Shares.  Each Excluded Company
     Share issued and outstanding immediately prior to the Effective Time shall,
     by virtue of the Merger and without any action on the part of the holder
     thereof, no longer be outstanding, shall be canceled and retired without
     payment of any consideration therefor and shall cease to exist.

          (d) Merger Sub.  At the Effective Time, each share of common stock,
     par value $0.01 per share, of Merger Sub issued and outstanding immediately
     prior to the Effective Time shall be converted into one share of common
     stock of the Surviving Corporation, and the Surviving Corporation shall
     thereby become a wholly owned subsidiary of Parent.

          (e) Stock Options; Employee Benefit Plans.  At the Effective Time, all
     Stock Options (as defined in Section 5.14) outstanding at the Effective
     Time under each Company Plan (as defined in Section 3.11) shall be assumed
     by Parent in accordance with Section 5.14.

     SECTION 2.2  Exchange of Certificates for Shares.

     (a) Exchange Procedures.  At or prior to the Effective Time, Parent shall
deposit with such party as may be reasonably satisfactory to Parent and the
Company (the "Exchange Agent"), in trust for the benefit of the holders of
Company Common Shares, certificates representing shares of Parent Common Stock
required to effect the conversion of the Company Common Shares into the Merger
Consideration pursuant to Section 2.1(a) (including shares of Parent Common
Stock that are needed with respect to fractional shares as contemplated by
Section 2.2(d)). Parent shall make sufficient funds available to the Exchange
Agent from time to time as needed to pay cash in respect of dividends or other
distributions in accordance with Section 2.2(b). Promptly after the Effective
Time, but in no event later than three business days following the Closing Date,
the Surviving Corporation shall cause the Exchange Agent to mail to each holder
of record as of the Effective Time of a certificate representing Company Common
Shares (each a "Certificate") (other than holders of a Certificate in respect of
Excluded Company

                                       A-6


Shares) (i) a letter of transmittal specifying that delivery of the Certificates
shall be effected, and that risk of loss and title to the Certificates shall
pass, only upon delivery of the Certificates to the Exchange Agent, such letter
of transmittal to be in such form and to have such other provisions as Parent
and the Company may reasonably agree, and (ii) instructions for exchanging the
Certificates and receiving the Merger Consideration to which such holder shall
be entitled pursuant to Section 2.1(a). Subject to Section 2.2(g), upon
surrender of a Certificate for cancellation to the Exchange Agent together with
such letter of transmittal, duly executed, the holder of such Certificate shall
be entitled to receive in exchange therefor (i) a certificate representing that
number of whole shares of Parent Common Stock that such holder is entitled to
receive pursuant to Section 2.1(a) and (ii) a check in the aggregate amount
(after giving effect to any required tax withholdings) of (A) any cash in lieu
of fractional shares determined in accordance with Section 2.2(d) plus (B) any
cash dividends and any other dividends or other distributions that such holder
has the right to receive pursuant to the provisions of this Section 2.2. The
Certificate so surrendered shall forthwith be canceled. No interest will be paid
or accrued on any amount payable (for fractional shares, dividends or otherwise)
upon surrender of any Certificate. In the event of a transfer of ownership of
Company Common Shares that occurred prior to the Effective Time, but is not
registered in the transfer records of the Company, the Merger Consideration may
be issued and/or paid to such a transferee if the Certificate formerly
representing such Company Common Shares is presented to the Exchange Agent,
accompanied by all documents required to evidence and effect such transfer and
to evidence that any applicable stock transfer taxes have been paid. If any
certificate for shares of Parent Common Stock is to be issued in a name other
than that in which the Certificate surrendered in exchange therefor is
registered, it shall be a condition of such exchange that the Person requesting
such exchange shall pay any transfer or other taxes required by reason of the
issuance of certificates for shares of Parent Common Stock in a name other than
that of the registered holder of the Certificate surrendered, or shall establish
to the reasonable satisfaction of Parent or the Exchange Agent that such tax has
been paid or is not applicable.

     (b) Distributions with Respect to Unexchanged Shares.  Whenever a dividend
or other distribution is declared by Parent in respect of Parent Common Stock,
the record date for which is at or after the Effective Time, that declaration
shall include dividends or other distributions in respect of all shares of
Parent Common Stock issuable pursuant to this Agreement. No dividends or other
distributions so declared in respect of such Parent Common Stock shall be paid
to any holder of any unsurrendered Certificate until such Certificate is
surrendered for exchange in accordance with this Section 2.2. Subject to the
effect of applicable laws, following surrender of any such Certificate, there
shall be issued or paid, less the amount of any withholding taxes that may be
required thereon, to the holder of the certificates representing whole shares of
Parent Common Stock issued in exchange for such Certificate, without interest,
(i) at the time of such surrender, the dividends or other distributions with a
record date that is at or after the Effective Time and a payment date on or
prior to the date of surrender of such whole shares of Parent Common Stock and
not previously paid and (ii) at the appropriate payment date, the dividends or
other distributions payable with respect to such whole shares of Parent Common
Stock with a record date at or after the Effective Time but with a payment date
subsequent to surrender. No interest shall be payable with respect to any
amounts to be paid under this Section 2.2. For purposes of dividends or other
distributions in respect of shares of Parent Common Stock, all shares of Parent
Common Stock to be issued pursuant to the Merger shall be deemed issued and
outstanding as of the Effective Time.

     (c) Transfers.  After the Effective Time, there shall be no transfers on
the stock transfer books of the Company of the Company Common Shares that were
outstanding immediately prior to the Effective Time.

     (d) Fractional Shares.

          (i) No certificates or scrip representing fractional shares of Parent
     Common Stock or book-entry credit of the same shall be issued upon the
     surrender for exchange of Certificates or upon conversion of shares, and
     such fractional share interest shall not entitle the owner thereof to vote
     or to any rights of a shareholder of Parent.

                                       A-7


          (ii) As promptly as practicable following the Effective Time, the
     Exchange Agent shall determine the excess of (A) the aggregate number of
     shares of Parent Common Stock that would be distributed to holders of the
     Certificates pursuant to Section 2.1(a) if no effect were given to Section
     2.2(d)(i) over (B) the aggregate number of whole shares of Parent Common
     Stock to be distributed to holders of the Certificates pursuant Section
     2.1(a) taking into account the effect of Section 2.2(d)(i) (such excess,
     the "Excess Shares"). As soon as practicable after the Effective Time, the
     Exchange Agent, as agent for the holders of the Certificates, shall sell
     the Excess Shares at then-prevailing prices on the American Stock Exchange
     ("AMEX"), all in the manner provided in Section 2.2(d)(iii).

          (iii) The sale of the Excess Shares by the Exchange Agent shall be
     executed on the AMEX and shall be executed in round lots to the extent
     practicable. The Surviving Corporation shall pay all commissions, transfer
     taxes and other out-of-pocket transaction costs, including the expenses and
     compensation of the Exchange Agent, incurred in connection with such sale
     of the Excess Shares. Until the proceeds of such sale or sales have been
     distributed to the holders of the Certificates (or paid to Parent pursuant
     to Section 2.2(e)), the Exchange Agent shall hold such proceeds in trust
     for the holders of the Certificates (the "Common Stock Trust"). The
     Exchange Agent shall determine the portion of the Common Stock Trust to
     which each holder of a Certificate shall be entitled, if any, by
     multiplying the amount of the aggregate net proceeds comprising the Common
     Stock Trust by a fraction, the numerator of which is the amount of the
     fractional share interest in the Parent Common Stock to which such holder
     of a Certificate is entitled and the denominator of which is the aggregate
     amount of fractional share interests in the Parent Common Stock to which
     all holders of the Certificates are entitled. Parent shall comply with the
     provisions of Rule 236(c) under the Securities Act of 1933, as amended (the
     "Securities Act").

          (iv) As soon as practicable after the determination of the amount of
     cash, if any, to be paid to holders of Certificates in lieu of any
     fractional share interests, the Exchange Agent shall make available such
     amounts, without interest, to such holders of Certificates that have
     surrendered their Certificates in accordance with this Section 2.2.

     (e) Termination of Exchange Period; Unclaimed Merger Consideration.  Any
shares of Parent Common Stock, any portion of the Common Stock Trust and any
portion of the cash, dividends or other distributions with respect to the Parent
Common Stock deposited by Parent with the Exchange Agent (including the proceeds
of any investments thereof) that remain unclaimed by the former stockholders of
the Company one year after the Effective Time shall be transferred to Parent.
Any former stockholders of the Company who have not theretofore complied with
this Section 2.2 shall thereafter be entitled to look only to Parent for payment
of their Merger Consideration and any cash, dividends and other distributions in
respect thereof issuable and/or payable pursuant to Section 2.1, Section 2.2(b)
and Section 2.2(d) upon due surrender of their Certificates, in each case,
without any interest thereon. Notwithstanding the foregoing, none of Parent, the
Surviving Corporation, the Exchange Agent or any other Person shall be liable to
any former holder of Company Common Shares for any amount properly delivered to
a public official pursuant to applicable abandoned property, escheat or similar
laws. If any Certificate shall not have been surrendered immediately prior to
the date on which any Merger Consideration would escheat to or become the
property of any governmental entity, any such Merger Consideration shall, to the
extent permitted by applicable law, become the property of Parent, free and
clear of all claims or interest of any person previously entitled thereto.

     (f) Lost, Stolen or Destroyed Certificates.  In the event any Certificate
shall have been lost, stolen or destroyed, upon the making of an affidavit of
that fact by the Person claiming such Certificate to be lost, stolen or
destroyed, and if Parent believes that the Person providing the indemnity is
sufficiently creditworthy, the making of a reasonable undertaking to indemnify
Parent or the Company, or, if Parent does not so believe, the posting by such
Person of a bond in the form customarily required by Parent to indemnify against
any claim that may be made against it with respect to such Certificate, Parent
will issue the shares of Parent Common Stock and the Exchange Agent will
distribute such Merger Consideration, dividends and other distributions in
respect thereof issuable or payable in exchange for such lost, stolen or
                                       A-8


destroyed Certificate pursuant to Section 2.1, Section 2.2(b) and Section
2.2(d), in each case, without interest. Any delivery or surrender for exchange
of a Certificate pursuant to this Section 2.2 may be effected (in lieu of such
delivery or exchange for surrender of a Certificate) by delivery of an affidavit
together with an indemnity undertaking or indemnity bond in accordance with this
Section 2.2(f).

     (g) Affiliates.  Notwithstanding anything in this Agreement to the
contrary, Certificates surrendered for exchange by any Rule 145 Affiliate (as
determined pursuant to Section 5.11) of the Company shall not be exchanged until
Parent has received a written agreement from such Person as provided in Section
5.11.

     SECTION 2.3  Appraisal Rights.  The parties hereto agree that, in
accordance with Section 262 of the DGCL, no appraisal rights will be available
to holders of Company Common Shares in connection with the Merger.
Notwithstanding anything in this Agreement to the contrary, Company Preferred
Shares issued and outstanding immediately prior to the Effective Time that are
held by any holder who is entitled to demand and properly demands appraisal of
such shares (the "Appraisal Shares") pursuant to, and who complies in all
respects with, the provisions of Section 262 of the DGCL ("Section 262") shall
be entitled to payment of the fair value of such shares in accordance with the
provisions of Section 262. At the Effective Time, all Appraisal Shares shall
automatically be canceled and shall cease to exist or be outstanding, and each
holder of Appraisal Shares shall cease to have any rights with respect thereto,
except the right to receive the fair value of such shares in accordance with the
provisions of Section 262. Notwithstanding the foregoing, if any such holder
shall fail to perfect or otherwise shall waive, withdraw or lose the right to
appraisal under Section 262 or a court of competent jurisdiction shall determine
that such holder is not entitled to the relief provided by Section 262, then the
right of such holder to be paid the fair value of such holder's Appraisal Shares
under Section 262 shall cease to exist and such Appraisal Shares shall remain
outstanding as provided in Section 2.1(b). The Company shall serve prompt notice
to Parent of any demands for appraisal of any Company Preferred Shares, and
Parent shall have the right to participate in and, subject to applicable law,
direct all negotiations and proceedings with respect to such demands. The
Company shall not, without the prior written consent of Parent, make any payment
with respect to, settle or offer to settle, any such demands, or agree to do any
of the foregoing.

     SECTION 2.4  Adjustments.  In the event that prior to the Effective Time,
there shall have been declared or effected a stock split, reverse stock split,
stock dividend or stock distribution (including any dividend, or distribution,
of securities convertible into Company Common Shares or Parent Common Stock),
reorganization, recapitalization, reclassification or similar event made with
respect to the Company Common Shares or the Parent Common Stock, the Exchange
Ratio shall be adjusted to reflect fully the appropriate effect of such event.

                                   ARTICLE 3

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

     Except as set forth in the disclosure letter delivered to Parent
concurrently with the execution hereof (the "Company Disclosure Letter") or as
disclosed with reasonable specificity in the Company Reports (as defined in
Section 3.7), the Company represents and warrants to Parent that:

     SECTION 3.1  Existence; Good Standing; Corporate Authority.  The Company is
a corporation duly incorporated, validly existing and in good standing under the
laws of the State of Delaware. The Company is duly qualified to do business as a
foreign corporation and is in good standing under the laws of each jurisdiction
in which the character of the properties owned or leased by it therein or in
which the transaction of its business makes such qualification necessary, except
where the failure to be so qualified would not have or reasonably be expected to
have, individually or in the aggregate, a Company Material Adverse Effect (as
defined in Section 8.9). The Company has all requisite corporate power and

Subsidiaries. The Company has no outstanding bonds, debentures, notes or other
obligations the holders of which have the right to vote (or which are

     SECTION 3.4  Significant Subsidiaries.  For purposes of this Agreement,

limited liability company or partnership power and authority to own, operate and
lease its properties and to carry on its business as it is now being conducted,
and is duly qualified to do business and is in good standing (where applicable)
in each jurisdiction in which the ownership, operation or lease of its property
or the conduct of its business requires such qualification, except for
jurisdictions in which such failure to be so qualified or to be in good standing
would not have or reasonably be expected to have, individually or in the
aggregate, a Company Material Adverse Effect. All of the outstanding shares of
capital stock of, or other ownership interests in, each of the Company's
Significant Subsidiaries is duly authorized, validly issued, fully paid and
nonassessable, and is owned, directly or indirectly, by the Company free and

failure to receive such consents or other certificates would not have or
reasonably be expected to have, individually or in the aggregate, a Company
Material Adverse Effect.

     operations, assets, businesses, or Company Real Properties.

     Neither the Company nor its Subsidiaries make any representation or
warranty regarding compliance or failure to comply with, or any actual or
contingent liability under, any Environmental Law, except as expressly set forth
in this Section 3.13.

     SECTION 3.14  Intellectual Property.  The Company and its Subsidiaries own
or possess all necessary licenses or other valid rights to use all patents,
patent rights, trademarks, trademark rights and proprietary information used or
held for use in connection with their respective businesses as currently being
conducted, free and clear of material Liens, except where the failure to own or
possess such licenses and other rights would not have or reasonably be expected
to have, individually or in the aggregate, a Company Material Adverse Effect,
and there are no assertions or claims challenging the validity of any of the
foregoing which would have or reasonably be expected to have, individually or in
the aggregate, a Company Material Adverse Effect. Except in the ordinary course
of business, neither the Company nor any of its Subsidiaries has granted to any
other person any license to use any of the foregoing. The conduct of the
Company's and its Subsidiaries' respective businesses as currently conducted
does not conflict with any patents, patent rights, licenses, trademarks,
trademark rights, trade names, trade name rights or copyrights of others in a
way which would have or reasonably be expected to have, individually or in the
aggregate, a Company Material Adverse Effect. There is no infringement of any
proprietary right owned by or licensed by or to the Company or any of its
Subsidiaries in a way which would have or reasonably be expected to have,
individually or in the aggregate, a Company Material Adverse Effect.

     SECTION 3.15  Title to Properties.  Except for goods and other property
sold, used or otherwise disposed of since September 30, 2002 in the ordinary
course of business for fair value, as of the date hereof, the Company has
defensible title for oil and gas purposes to all its properties, interests in
properties and assets, real and personal, reflected in the Company's September
30, 2002 financial statements included in the Company Reports, free and clear of
any Lien, except: (a) Liens reflected in the balance sheet of the Company as of
September 30, 2002 included in the Company Reports; (b) Liens for current taxes
not yet due and payable; and (c) such imperfections of title, easements and
Liens that would not have or reasonably be expected to have, individually or in
the aggregate, a Company Material Adverse Effect. All leases and other
agreements pursuant to which the Company or any of its Subsidiaries leases or
otherwise acquires or obtains operating rights affecting any real or personal
property are in good standing, valid, and effective, except where the failure to
be in good standing, valid or effective would not have or reasonably be expected
to have, individually or in the aggregate, a Company Material Adverse Effect;
and there is not, under any such leases, any existing or prospective default or
event of default or event which with notice or lapse of time, or both, would
constitute a default by the Company or any of its Subsidiaries that would have
or reasonably be expected to have, individually or in the aggregate, a Company
Material Adverse Effect. All significant operating equipment of the Company and
its Subsidiaries is in good operating condition, ordinary wear and tear
excepted. The Company has not received any material advance, take-or-pay or
other similar payments that entitle purchasers of production to receive
deliveries of hydrocarbons without paying therefor, and, on a net, company-wide
basis, the Company is neither underproduced nor overproduced, in either case, to
any material extent, under gas balancing or similar arrangements.

     SECTION 3.16  Insurance.  The Company and its Subsidiaries maintain
insurance coverage adequate and customary in the industry for the operation of
their respective businesses (taking into account the cost and availability of
such insurance).

     SECTION 3.17  No Brokers.  The Company has not entered into any contract,
arrangement or understanding with any person or firm which may result in the
obligation of Parent, Merger Sub or the Company to pay any finder's fees,
brokerage or agent's commissions or other like payments in connection with the
negotiations leading to this Agreement or the consummation of the transactions
contemplated hereby, except that the Company has retained Deutsche Banc
Securities Inc. to act as its financial advisor in connection with the Merger
and render the opinion referred to in Section 3.18, the terms of which

                                       A-17


(including the fees owed by the Company in connection therewith) have been
disclosed in writing to Parent prior to the date hereof.

     SECTION 3.18  Opinion of Financial Advisor.  The Board of Directors of the
Company has received the opinion of Deutsche Bank Securities Inc. to the effect
that the Exchange Ratio is fair, from a financial point of view, to the holders
of the Company Common Shares (other than Parent and its Subsidiaries); it being
understood and acknowledged by Parent that such opinion has been rendered for
the benefit of the Board of Directors of the Company, and is not intended to,
and may not, be relied upon by Parent, its affiliates or their respective
Subsidiaries.

     SECTION 3.19  Contracts; Debt Instruments.

     (a) Except for documents filed or listed as exhibits to the Company Reports
filed since December 31, 2001, there are no contracts that are material to the
business, properties, assets, financial condition or results of operations of
the Company and its Subsidiaries taken as a whole ("Company Material
Contracts"). Neither the Company nor any of its Subsidiaries is in violation of
or in default under (nor does there exist any condition which with the passage
of time or the giving of notice or both would cause such a violation of or
default under) any Company Material Contract to which it is a party or by which
it or any of its properties or assets is bound, except for violations or
defaults that would not have or reasonably be expected to have, individually or
in the aggregate, a Company Material Adverse Effect. Each Company Material
Contract is in full force and effect, and is a legal, valid and binding
obligation of the Company or one of its Subsidiaries and, to the knowledge of
the Company, each of the other parties thereto, enforceable in accordance with
its terms, except as such enforceability may be limited by bankruptcy,
insolvency, moratorium or other similar laws relating to creditors' rights and
general principles of equity and except where the failure of any Company
Material Contract to be a legal, valid and binding obligation and enforceable in
accordance with its terms would not have or reasonably be expected to have,
individually or in the aggregate, a Company Adverse Effect. No condition exists
or event has occurred which (whether with or without notice or lapse of time or
both) would constitute a default by the Company or one of its Subsidiaries or,
to the knowledge of the Company, any other party thereto under any Company
Material Contract or result in a right of termination of any Company Material
Contract, except for any condition or event that would not have or reasonably be
expected to have, individually or in the aggregate, a Company Adverse Effect.

     (b) Set forth in Schedule 3.19(b) of the Company Disclosure Letter is, as
of the date hereof, (i) a list of all loan or credit agreements, notes, bonds,
mortgages, indentures and other agreements and instruments pursuant to which any
indebtedness of the Company or its Subsidiaries in an aggregate principal amount
in excess of $50,000,000 is outstanding or may be incurred, and (ii) the
respective principal amounts outstanding thereunder as of February 21, 2003.

     (c) Neither the Company nor any of its Subsidiaries has entered into any
contract and there is no commitment, judgment, injunction, order or decree to
which the Company or any of its Subsidiaries is a party or subject to that has
or would reasonably be expected to have the effect of prohibiting or impairing
the conduct of business by the Company or any of its Subsidiaries or any
contract that may be terminable as a result of Parent's status as a competitor
of any party to such contract, except, in each case, for any prohibition,
impairment or termination right that would not have or reasonably be expected to
have, individually or in the aggregate, a Company Material Adverse Effect.

     (d) The Company and James T. Hackett have executed (i) a third amendment to
the employment agreement by and between the Company and James T. Hackett,
initially effective as of September 16, 1998 (the "Employment Agreement"), in
the form of Exhibit B attached hereto (the "Employment Agreement Amendment") and
(ii) a second amendment to the severance agreement by and between the Company
and James T. Hackett, initially effective as of August 25, 1998 (the "Severance
Agreement"), in the form of Exhibit C attached hereto (the "Severance Agreement
Amendment"), and each of the Employment Agreement, as amended by the Employment
Agreement Amendment, and the Severance Agreement, as amended by the Severance
Agreement Amendment, shall be effective at the Effective Time (it being
understood that, prior to the Effective Time and only with the consent of each
of Parent, the
                                       A-18


Company and James T. Hackett, the Company and James T. Hackett may enter into an
employment agreement (the "New Employment Agreement") incorporating the terms of
each of the Employment Agreement (as amended by the Employment Agreement
Amendment) and the Severance Agreement (as amended by the Severance Agreement
Amendment), which New Employment Agreement, if entered into as contemplated by
this parenthetical, shall be effective as of the Effective Time).

     SECTION 3.20  Vote Required.  The affirmative vote of holders of a majority
in interest of the voting power of the outstanding Company Shares (with the
Company Preferred Shares voting on an as-converted basis), voting as a single
class, is the only vote necessary to adopt this Agreement and the transactions
contemplated hereby (as applied to this Agreement and the transactions
contemplated hereby, the "Company Requisite Vote").

     Section 3.21  Certain Approvals.  The Company's Board of Directors has
taken any and all necessary and appropriate action to render inapplicable to the
Merger and the transactions contemplated by this Agreement the restrictions
contained in Section 203 of the DGCL and any other "fair price," "moratorium,"
control share acquisition, interested shareholder or other similar antitakeover
provision or regulation and any restrictive provision of any antitakeover
provision in the certificate of incorporation or bylaws of the Company.

     Section 3.22  Certain Contracts.  Neither the Company nor any of its
Subsidiaries is a party to or bound by (i) any non-competition agreement or any
other agreement or obligation which purports to limit the manner in which, or
the localities in which, the current business of the Company and its
Subsidiaries, taken as a whole, or Parent and its Subsidiaries, taken as a
whole, is conducted or (ii) any executory agreement or obligation which pertains
to the acquisition or disposition of any asset, or which provides any third
party any lien, claim or preferential right with regard thereto, except, in the
case of this clause (ii), for such agreements or obligations that would not have
or reasonably be expected to have, individually or in the aggregate, a Company
Material Adverse Effect.

     Section 3.23  Rights Agreement.  The Company has adopted an amendment to
the Company Rights Agreement with the effect that (i) neither Parent nor Merger
Sub shall be deemed to be an Acquiring Person (as defined in the Company Rights
Agreement), the Distribution Date (as defined in the Company Rights Agreement)
shall not be deemed to occur, and the Rights (as defined in the Company Rights
Agreement) will not separate from the Company Common Shares, as a result of
entering into this Agreement or consummating the Merger and/or the other
transactions contemplated by this Agreement and (ii) the Rights will expire
immediately prior to the Effective Time. The Company has made available to
Parent a true and complete copy of the Company Rights Agreement, as amended to
date.

                       REPRESENTATIONS AND WARRANTIES OF
                             PARENT AND MERGER SUB

     Except as set forth in the disclosure letter delivered to the Company
concurrently with the execution hereof (the "Parent Disclosure Letter") or as
disclosed with reasonable specificity in the Parent Reports (as defined in
Section 4.7), Parent and Merger Sub, jointly and severally, represent and
warrant to the Company that:

     SECTION 4.1  Existence; Good Standing; Corporate Authority.  Each of Parent
and Merger Sub is a corporation duly incorporated, validly existing and in good
standing under the laws of the State of Delaware. Each of Parent and Merger Sub
is duly qualified to do business as a foreign corporation and is in good
standing under the laws of each jurisdiction in which the character of the
properties owned or leased by it therein or in which the transaction of its
business makes such qualification necessary, except where the failure to be so
qualified would not have or reasonably be expected to have, individually or in
the aggregate, a Parent Material Adverse Effect (as defined in Section 8.9).
Each of Parent and Merger Sub has all requisite corporate power and authority to
own, operate and lease its properties and to carry on its business as now
conducted. The copies of each of Parent's and Merger Sub's certificate of
incorporation
                                       A-19


and bylaws previously made available to the Company are true and correct and
contain all amendments as of the date hereof.

     SECTION 4.2  Authorization, Validity and Effect of Agreements.  Each of
Parent and Merger Sub has the requisite corporate power and authority to execute
and deliver this Agreement and all other agreements and documents contemplated
hereby to which it is a party. The consummation by each of Parent and Merger Sub
of the transactions contemplated hereby, including the issuance and delivery by
Parent of shares of Parent Common Stock pursuant to the Merger, has been duly
authorized by all requisite corporate action, other than, with respect to the
Merger, the approval of the issuance of Parent Common Stock pursuant to the
Merger by Parent's stockholders. This Agreement constitutes the valid and
legally binding obligation of each of Parent and Merger Sub, enforceable in
accordance with its terms, subject to applicable bankruptcy, insolvency,
moratorium or other similar laws relating to creditors' rights and general
principles of equity.

     SECTION 4.3  Capitalization.  The authorized capital stock of Parent
consists of 400,000,000 shares of Parent Common Stock, one share of Parent
Special Voting Stock, par value $0.10 per share, and 4,500,000 shares of
Parent's preferred stock, par value $1.00 per share ("Parent Preferred Stock").
As of February 20, 2003, there were (a) 156,798,464 shares of Parent Common
Stock issued and outstanding, (b) one share of Parent Special Voting Stock
issued and outstanding, (c) 1,270,668 shares of Parent Common Stock reserved for
issuance pursuant to options issued under the stock options plans of Parent (the
"Parent Option Plans") described in Schedule 4.3 of the Parent Disclosure
Letter, (d) 49,209 shares of Parent Common Stock reserved for issuance under the
Parent Restricted Stock Award Plan, (e) 1,680,637 shares reserved for issuance

6.49% Cumulative Preferred Stock, Series A, issued and outstanding, (g)
2,000,000 unissued shares of Parent Preferred Stock designated as Series A

4,377,068 shares of Parent Common Stock reserved for issuance upon conversion of
the $760,000,000 of Zero Coupon Convertible Senior Debentures due 2020 (the

Stock, Parent Special Voting Stock, and Parent Preferred Stock (i) are duly
authorized, validly issued, fully paid, nonassessable and free of preemptive
rights, (ii) were not issued in violation of the terms of any agreement or other
understanding binding upon Parent and (iii) were issued in compliance with all
applicable charter documents of Parent and all applicable federal and state
securities laws, rules and regulations. One right to purchase Series A Junior
Participating Preferred Stock of Parent (each, a "Parent Right") issued pursuant
to a Rights Agreement, dated as of August 17, 1999 (as amended, the "Parent
Rights Agreement"), between Parent and Wachovia Bank, N.A., is associated with
and attached to each outstanding share of Parent Common Stock. The shares of
Parent Common Stock to be issued in connection with the Merger, when issued in
accordance with this Agreement, will be validly issued, fully paid and
nonassessable and free of preemptive rights. Except (i) as set forth in this
Section 4.3, (ii) for any Parent Common Stock issuable upon conversion or

issuable pursuant to Parent Rights, there are no outstanding shares of capital
stock and there are no options, warrants, calls, subscriptions, shareholder
rights plan or similar instruments, convertible securities, or other rights,
agreements or commitments which obligate Parent or any of its Subsidiaries to
issue, transfer or sell any shares of capital stock or other voting securities
of Parent or any of its Subsidiaries. Except as set forth in this Section 4.3,
Parent has no outstanding bonds, debentures, notes or other obligations the
holders of which have the right to vote (or which are convertible into or
exercisable for securities having the right to vote) with the stockholders of
Parent on any matter.

or organization, has the corporate, limited liability company or partnership
power and authority to own, operate and lease its properties and to carry on its
business as it is now being conducted, and is duly qualified to do business and
is in good standing (where applicable) in each jurisdiction in which the
ownership, operation or lease of its property or the conduct of its business
requires such qualification, except for jurisdictions in which such failure to
be so qualified or to be in good standing would not have or reasonably be
expected to have, individually or in the aggregate, a Parent Material Adverse
Effect. All of the outstanding shares of capital stock of, or other ownership
interests in, each of Parent's Significant Subsidiaries is duly authorized,
validly issued, fully paid and nonassessable, and is owned, directly or
indirectly, by Parent free and clear of all Liens. Schedule 4.4 of the Parent

Significant Subsidiary, is a limited partnership (except for tax purposes) duly
organized and validly existing under Oklahoma law, the general partner of which
is Devon Energy Management Company, L.L.C., an Oklahoma limited liability
company which is wholly owned by Devon Energy Corporation (Oklahoma), an
Oklahoma corporation, and has elected to be treated as a sole proprietorship for
federal income tax purposes. Devon Production has one limited partner. All of
the outstanding partnership interests of Devon Production are owned directly or
indirectly by Parent.

     (c) All of the outstanding shares of capital stock of Merger Sub are owned
directly by Parent. Merger Sub was formed solely for the purpose of engaging in
the transactions contemplated hereby and has not engaged in any activities other

     SECTION 4.5  No Violation.  Neither Parent nor any of its Subsidiaries is,
or has received notice that it would be with the passage of time, in violation
of any term, condition or provision of (a) its charter documents or bylaws, (b)
any loan or credit agreement, note, bond, mortgage, indenture, contract,
agreement, lease, license or other instrument or (c) any order of any court,
governmental authority or arbitration board or tribunal, or any law, ordinance,
governmental rule or regulation to which Parent or any of its Subsidiaries or
any of their respective properties or assets is subject, or is delinquent with
respect to any report required to be filed with any governmental entity, except,
in the case of matters described in clause (b) or (c), as would not have or
reasonably be expected to have, individually or in the aggregate, a Parent
Material Adverse Effect. Except as would not have or reasonably be expected to
have, individually or in the aggregate, a Parent Material Adverse Effect, (i)
Parent and its Subsidiaries hold all permits, licenses, variances, exemptions,
orders, franchises and approvals of all governmental authorities necessary for
the lawful conduct of their respective businesses (the "Parent Permits") and

threatened, other than those that would not have or reasonably be expected to
have, individually or in the aggregate, a Parent Material Adverse Effect.

     SECTION 4.6  No Conflict.

     (a) Neither the execution and delivery by Parent and Merger Sub of this
Agreement nor the consummation by Parent and Merger Sub of the transactions
contemplated hereby in accordance with the terms hereof will: (i) conflict with
or result in a breach of any provisions of the charter documents or bylaws of
Parent or Merger Sub; (ii) violate, or conflict with, or result in a breach of
any provision of, or constitute a default (or an event which, with notice or
lapse of time or both, would constitute a default) under, or result in the
termination or in a right of termination or cancellation of, or give rise to a
right of purchase under, or accelerate the performance required by, or result in
the creation of any Lien upon any of the properties of Parent or its
Subsidiaries under, or result in being declared void, voidable, or without
                                       A-21


further binding effect, or otherwise result in a detriment to Parent or any of
its Subsidiaries under any of the terms, conditions or provisions of, any note,
bond, mortgage, indenture, deed of trust, Parent Permit, lease, contract,
agreement, joint venture or other instrument or obligation to which Parent or

individually or in the aggregate, a Parent Material Adverse Effect.

     (b) Neither the execution and delivery by Parent or Merger Sub of this
Agreement nor the consummation by Parent or Merger Sub of the transactions
contemplated hereby in accordance with the terms hereof will require any
consent, approval or authorization of, or filing or registration with, any
governmental or regulatory authority, other than Regulatory Filings, and listing
of the Parent Common Stock to be issued in the Merger on the AMEX, except for
any consent, approval or authorization the failure of which to obtain and for
any filing or registration the failure of which to make would not have or
reasonably be expected to have, individually or in the aggregate, a Parent
Material Adverse Effect.

     (c) Other than as contemplated by Section 4.6(b), no consents, assignments,
waivers, authorizations or other certificates are necessary in connection with
the transactions contemplated hereby to provide for the continuation in full
force and effect of all of Parent's material contracts or leases or for Parent
to consummate the transactions contemplated hereby, except where the failure to
receive such consents or other certificates would not have or reasonably be
expected to have, individually or in the aggregate, a Parent Material Adverse
Effect.

     (d) Neither the execution and delivery of this Agreement nor the
consummation of the transactions contemplated hereby will: (i) result in any
payment from Parent or its Subsidiaries (including severance, unemployment
compensation, parachute payment, bonus or otherwise) becoming due to any
director, employee or independent contractor of Parent or any of its
Subsidiaries under any Parent Plan (as defined in Section 4.11) or otherwise;
(ii) increase any benefits otherwise payable under any Parent Plan or otherwise;

financial position of Parent and its Subsidiaries as of its date and each of the
consolidated statements of operations, cash flows and stockholders' equity
included in or incorporated by reference into the Parent Reports (including any
related notes and schedules) fairly presents in all material respects the

case may be, of Parent and its Subsidiaries for the periods set forth therein
(subject, in the case of unaudited statements, to such exceptions as may be
permitted by Form 10-Q of the SEC), in each case in accordance with generally
accepted accounting principles consistently applied during the periods involved,
except as may be noted therein.

     SECTION 4.8  Litigation and Liabilities.  There are no actions, suits or
proceedings pending against Parent or any of its Subsidiaries or, to Parent's

aggregate, a Parent Material Adverse Effect. There are no outstanding judgments,
decrees, injunctions, awards or orders against Parent or any of its
Subsidiaries, other than those that would not have or reasonably be expected to
have, individually or in the aggregate, a Parent Material Adverse Effect. There

Parent of any such stock; (v) any change in the capital stock or in the number
of shares or classes of Parent's authorized or outstanding capital stock (other

options to purchase the Parent Common Stock outstanding or issued, or such other
issuances of capital stock, in each case, as permitted hereunder pursuant to
Section 5.1(b)(vi)); or (vi) any increase in or establishment of any bonus,
insurance, severance, deferred compensation, pension, retirement, profit
sharing, stock option, stock purchase or other employee benefit plan, except in
the ordinary course of business or (vii) any event, condition, action or
occurrence that is prohibited on or after the date of this Agreement under

behalf) on a timely basis (taking into account any extensions of time to file

faith by Parent or a Subsidiary of Parent and except to the extent that any

     (b) Except for matters that would not have or reasonably be expected to
have, individually or in the aggregate, a Parent Material Adverse Effect, (i)

be expected to have, individually or in the aggregate, a Parent Material Adverse
Effect.

     (d) All Parent Plans comply in form and have been administered in operation
in all material respects with all applicable requirements of law, excluding any
deficiencies that would not have or reasonably be expected to have, individually
or in the aggregate, a Parent Material Adverse Effect, no event has occurred

respects, with the requirements of ERISA, the Code and any other applicable tax

would have or reasonably be expected to have, individually or in the aggregate,
a Parent Material Adverse Effect.

     (m) There have been no acts or omissions by Parent or any of its
Subsidiaries which have given rise to or may give rise to fines, penalties,
taxes or related charges under section 502 of ERISA or Chapters 43, 47, 68 or
100 of the Code for which Parent or any of its Subsidiaries may be liable that
would reasonably be expected to result in a Parent Material Adverse Effect.

     (n) Each Parent Plan which constitutes a "group health plan" (as defined in
section 607(1) of ERISA or section 4980B(g)(2) of the Code), including any plans
of current and former affiliates which must be taken into account under sections
4980B and 414(t) of the Code or section 601 of ERISA, has been operated in

such leases, any existing or prospective default or event of default or event
which with notice or lapse of time, or both, would constitute a default by
Parent or any of its Subsidiaries that would have or reasonably be expected to
have, individually or in the aggregate, a Parent Material Adverse Effect. All
significant operating equipment of Parent and its Subsidiaries is in good
operating condition, ordinary wear and tear excepted. Parent has not received
any material advance, take-or-pay or other similar payments that entitle

negotiations leading to this Agreement or the consummation of the transactions
contemplated hereby, except that Parent has retained Morgan Stanley to act as
its financial advisor in connection with the Merger and render the opinion

Parent in connection therewith) have been disclosed in writing to the Company
prior to the date hereof.

Parent has received the opinion of Morgan Stanley to the effect that the
Exchange Ratio is fair, from a financial point of view, to Parent; it being
understood and acknowledged by Parent that such opinion has been rendered for
the benefit of the Board of Directors of Parent, and is not intended to, and may
not, be relied upon by the Company, its affiliates or their respective
Subsidiaries.

     SECTION 4.19  Contracts; Debt Instruments

     (a) Except for documents filed or listed as exhibits to the Parent Reports
filed since December 31, 2001, as of the date hereof, there are no contracts
that are material to the business, properties, assets, financial condition or
results of operations of Parent and its Subsidiaries taken as a whole ("Parent
Material Contracts"). Neither Parent nor any of its Subsidiaries is in violation
of or in default under (nor does there exist any condition which with the
passage of time or the giving of notice or both would cause such a violation of
or default under) any Parent Material Contract to which it is a party or by
which it or any of its properties or assets is bound, except for violations or
defaults that would not have or reasonably be expected to have, individually or
in the aggregate, a Parent Material Adverse Effect. Each Parent Material
Contract is in full force and effect, and is a legal, valid and binding
obligation of Parent or one of
                                       A-27


its Subsidiaries and, to the knowledge of Parent, each of the other parties
thereto, enforceable in accordance with its terms, except as such enforceability
may be limited by bankruptcy, insolvency, moratorium or other similar laws
relating to creditors' rights and general principles of equity and except where
the failure of any Parent Material Contract to be a legal, valid and binding
obligation and enforceable in accordance with its terms would not have or
reasonably be expected to have, individually or in the aggregate, a Parent
Adverse Effect. No condition exists or event has occurred which (whether with or
without notice or lapse of time or both) would constitute a default by Parent or
one of its Subsidiaries or, to the knowledge of Parent, any other party thereto
under any Parent Material Contract or result in a right of termination of any
Parent Material Contract, except for any condition or event that would not have
or reasonably be expected to have, individually or in the aggregate, a Parent
Adverse Effect.

     (b) Set forth in Schedule 4.19(b) of the Parent Disclosure Letter is, as of
the date hereof, (i) a list of all loan or credit agreements, notes, bonds,
mortgages, indentures and other agreements and instruments pursuant to which any
indebtedness of Parent or its Subsidiaries in an aggregate principal amount in
excess of $50,000,000 is outstanding or may be incurred, and (ii) the respective
principal amounts outstanding thereunder as of February 21, 2003.

     (c) Neither Parent nor any of its Subsidiaries has entered into any
contract and there is no commitment, judgment, injunction, order or decree to
which Parent or any of its Subsidiaries is a party or subject to that has or
would reasonably be expected to have the effect of prohibiting or impairing the
conduct of business by Parent or any of its Subsidiaries or any contract that
may be terminable as a result of the Company's status as a competitor of any
party to such contract, except, in each case, for any prohibition, impairment or
termination right that would not have or reasonably be expected to have,
individually or in the aggregate, a Parent Material Adverse Effect.

     SECTION 4.20  Vote Required.  The affirmative vote of the holders of a
majority of the votes cast in person or by proxy by holders of Parent Common
Stock and the outstanding Northstar Exchangeable Shares, voting as a single
class with the Parent Special Voting Stock (representing the Northstar
Exchangeable Shares as provided in Parent's certificate of incorporation),
represented in person or by proxy at a meeting at which a quorum is present,
approving the issuance of shares of Parent Common Stock required to be issued
pursuant to Article 2, is the only vote of the holders of any class or series of
Parent capital stock necessary to approve this Agreement and the transactions
contemplated hereby (as applied to the issuance of shares of Parent Common Stock
pursuant to this Agreement and the transactions contemplated hereby, the "Parent
Requisite Vote").

     Section 4.21  Certain Contracts.  Neither the Parent nor any of its
Subsidiaries is a party to or bound by (i) any non-competition agreement or any
other agreement or obligation which purports to limit the manner in which, or
the localities in which, the current business of Parent and its Subsidiaries,
taken as a whole, or the Company and its Subsidiaries, taken as a whole, is
conducted or (ii) any executory agreement or obligation which pertains to the
acquisition or disposition of any asset, or which provides any third party any
lien, claim or preferential right with regard thereto, except, in the case of
this clause (ii), for such agreements or obligations that would not have or
reasonably be expected to have, individually or in the aggregate, a Parent
Material Adverse Effect.

     Section 4.22  Rights Agreement.  No person shall be deemed to be an
Acquiring Person (as defined in the Parent Rights Agreement), the Distribution
Date (as defined in the Parent Rights Agreement) shall not be deemed to occur
and the Rights (as defined in the Parent Rights Agreement) will not separate
from the Parent Common Stock, as a result of entering into this Agreement or
consummating the Merger and/or the other transactions contemplated by this
Agreement. Parent has made available to the Company a true and complete copy of
the Parent Rights Agreement, as amended to date.

     other terms of this Agreement, shall not, and shall not permit any of its
     Subsidiaries to, terminate, amend, modify or waive any provision of any
     confidentiality or standstill agreement to which it or any of its
     Subsidiaries is a party; and during such period shall enforce, to the
     fullest extent permitted under applicable law, the provisions of such

     thereof in any court of the United States of America or any state having

     Subsidiaries' (taken as a whole) estimated production of proved reserves of
     these commodities during that period, (B) any period in 2004 in which the
     volume hedged is more than 35% of its and its Subsidiaries' (taken as a
     whole) estimated production of proved reserves of these commodities during
     that period, or (C) any period after December 31, 2004;

     the other provisions of the Parent Rights Agreement, as applicable;

     shares of capital stock;

          (xxi) shall not purchase any Company Common Stock;

          (xxii) shall not, and shall not permit any of its Subsidiaries to, (A)

     venture, partnership or other joint business venture with any person in
     which the fair market value of Parent's or its Subsidiaries' aggregate

          (xxiii) shall not, nor shall it permit any of its Subsidiaries to,

     SECTION 5.2  No Solicitation by the Company.

     (a) The Company agrees that it and its Subsidiaries (i) will not (and the
Company will not permit its or its Subsidiaries' officers, directors, employees,
agents or representatives, including any investment banker, attorney or
accountant retained by the Company or any of its Subsidiaries, to) solicit,
initiate or encourage (including by way of furnishing non-public information)
any inquiry, proposal or offer (including any proposal or offer to its
stockholders) with respect to a third party tender offer, merger, consolidation,
business combination or similar transaction involving any assets or class of
capital stock of the Company, or any acquisition of 10% or more of the capital
stock of the Company (other than upon exercise of the Stock Options (as
hereinafter defined) that are outstanding as of the date hereof) or a
                                       A-33


business or assets that constitute 10% or more of the net revenues, net
operating income or assets of the Company and its Subsidiaries, taken as a
whole, in a single transaction or a series of related transactions, or any
combination of the foregoing (any such proposal, offer or transaction being
hereinafter referred to as a "Company Acquisition Proposal") or participate or
engage in any discussions or negotiations concerning a Company Acquisition
Proposal; and (ii) will immediately cease and cause to be terminated any
existing discussions or negotiations with any third parties conducted heretofore
with respect to any Company Acquisition Proposal; provided that, subject to
Section 5.4(b), nothing contained in this Agreement shall prevent the Company or
its Board of Directors from (A) complying with Rule 14e-2 promulgated under the
Exchange Act with regard to a Company Acquisition Proposal, (B) making any
disclosure to the holders of Company Shares if in the good faith judgment of the
Company's Board of Directors failure to make such disclosure would be
inconsistent with its fiduciary duties under applicable law or the rules of the
New York Stock Exchange or (C) providing information (pursuant to a
confidentiality agreement in reasonably customary form and which does not
contain terms that prevent the Company from complying with its obligations under
this Section 5.2) to or engaging in any negotiations or discussions with any
person or group who has made an unsolicited bona fide Company Acquisition
Proposal with respect to all the outstanding shares of capital stock of the
Company or all or substantially all of the assets of the Company if, with
respect to the actions set forth in clause (C), (x) in the good faith judgment
of the Company's Board of Directors, taking into account the likelihood of
consummation and after consultation with its financial advisors, such Company
Acquisition Proposal is reasonably likely to result in a transaction more
favorable to the holders of the Company Common Shares from a financial point of
view than the Merger (a "Company Superior Proposal") and (y) the Board of
Directors of the Company, after consultation with its outside legal counsel,
determines in good faith that the failure to do so would be inconsistent with
its fiduciary obligations under applicable law.

     (b) The Company agrees that it will notify Parent promptly (and in any
event within 24 hours) if any proposal or offer relating to or constituting a
Company Acquisition Proposal is received by, any information is requested from,
or any discussions or negotiations are sought to be initiated or continued with,
the Company or any of its officers, directors, employees, agents or
representatives. In connection with such notice, the Company shall indicate the
identity of the person or group making such request or inquiry or engaging in
such negotiations or discussions and the material terms and conditions of any
Company Acquisition Proposal. Thereafter, the Company shall keep Parent fully
informed on a prompt basis (and in any event within 24 hours) of any material
changes, additions or adjustments to the terms of any such proposal or offer.
Prior to taking any action referred to in clause (C) of the proviso of Section
5.2(a), if the Company intends to participate in any such discussions or
negotiations or provide any such information to any such third party, the
Company shall give notice to Parent.

     (c) Nothing in this Section 5.2 shall permit the Company to enter into any
agreement with respect to a Company Acquisition Proposal during the term of this
Agreement, it being agreed that, during the term of this Agreement, the Company
shall not enter into any agreement with any person that provides for, or in any
way facilitates, a Company Acquisition Proposal, other than a confidentiality
agreement and/or standstill agreement permitted under Section 5.2(a) in
reasonably customary form and which does not contain terms that prevent the
Company from complying with its obligations under this Section 5.2.

     SECTION 5.3  No Solicitation by Parent.

     (a) Parent agrees that it and its Subsidiaries (i) will not (and Parent
will not permit its or its Subsidiaries' officers, directors, employees, agents
or representatives, including any investment banker, attorney or accountant
retained by Parent or any of its Subsidiaries, to) solicit, initiate or
encourage (including by way of furnishing non-public information) any inquiry,
proposal or offer (including any proposal or offer to its stockholders) with
respect to a third party tender offer, merger, consolidation, business
combination or similar transaction involving any assets or class of capital
stock of Parent, or any acquisition of 10% or more of the capital stock of
Parent (other than upon exercise of options to acquire Parent Common Stock under
the Parent Option Plans that are outstanding as of the date hereof) or a
business or assets that constitute 10% or more of the net revenues, net
operating income or assets of Parent and its Subsidiaries, taken as a whole, in
a single transaction or a series of related transactions, or
                                       A-34


any combination of the foregoing (any such proposal, offer or transaction being
hereinafter referred to as a "Parent Acquisition Proposal") or participate or
engage in any discussions or negotiations concerning a Parent Acquisition
Proposal; and (ii) will immediately cease and cause to be terminated any
existing discussions or negotiations with any third parties conducted heretofore
with respect to any Parent Acquisition Proposal; provided that, subject to
Section 5.4(b), nothing contained in this Agreement shall prevent Parent or its
Board of Directors from (A) complying with Rule 14e-2 promulgated under the
Exchange Act with regard to a Parent Acquisition Proposal, (B) making any
disclosure to the holders of Parent Common Stock if in the good faith judgment
of Parent's Board of Directors failure to make such disclosure would be
inconsistent with its fiduciary duties under applicable law or the rules of the
AMEX or (C) providing information (pursuant to a confidentiality agreement in
reasonably customary form and which does not contain terms that prevent Parent
from complying with its obligations under this Section 5.3) to or engaging in
any negotiations or discussions with any person or group who has made an
unsolicited bona fide Parent Acquisition Proposal with respect to all the
outstanding shares of capital stock of Parent or all or substantially all of the
assets of Parent if, with respect to the actions set forth in clause (C), (x) in
the good faith judgment of Parent's Board of Directors, taking into account the
likelihood of consummation and after consultation with its financial advisors,
such Parent Acquisition Proposal is reasonably likely to result in a transaction
more favorable to the holders of the Parent Common Stock from a financial point
of view than the Merger (a "Parent Superior Proposal") and (y) the Board of
Directors of Parent, after consultation with its outside legal counsel,
determines in good faith that the failure to do so would be inconsistent with
its fiduciary obligations under applicable law.

     (b) Parent agrees that it will notify the Company promptly (and in any
event within 24 hours) if any proposal or offer relating to or constituting a
Parent Acquisition Proposal is received by, any information is requested from,
or any discussions or negotiations are sought to be initiated or continued with,
Parent or any of its officers, directors, employees, agents or representatives.
In connection with such notice, Parent shall indicate the identity of the person
or group making such request or inquiry or engaging in such negotiations or
discussions and the material terms and conditions of any Parent Acquisition
Proposal. Thereafter, Parent shall keep the Company fully informed on a prompt
basis (and in any event within 24 hours) of any material changes, additions or
adjustments to the terms of any such proposal or offer. Prior to taking action
any referred to in clause (C) of the proviso of Section 5.3(a), if Parent
intends to participate in any such discussions or negotiations or provide any
such information to any such third party, Parent shall give notice to the
Company.

     (c) Nothing in this Section 5.3 shall permit Parent to enter into any
agreement with respect to a Parent Acquisition Proposal during the term of this
Agreement, it being agreed that, during the term of this Agreement, Parent shall
not enter into any agreement with any person that provides for, or in any way
facilitates, a Parent Acquisition Proposal, other than a confidentiality
agreement and/or standstill agreement permitted under Section 5.3(a) in
reasonably customary form and which does not contain terms that prevent Parent
from complying with its obligation under this Section 5.3.

     SECTION 5.4  Meetings of Stockholders.

     (a) The Company will take all action necessary in accordance with
applicable law and its certificate of incorporation and bylaws to convene as
promptly as practicable a meeting of its stockholders for purposes of obtaining
the Company Requisite Vote in favor of approval and adoption of this Agreement
and the transactions contemplated hereby. Parent will take all action necessary
in accordance with applicable law and its certificate of incorporation and
bylaws to convene as promptly as practicable a meeting of its stockholders for
purposes of obtaining the Parent Requisite Vote in favor of the issuance of the
Parent Common Stock necessary to consummate the transactions contemplated
hereby. Parent and the Company shall each use their reasonable best efforts to
hold their respective stockholders meetings on the same day.

     (b) Except as otherwise permitted by this Section 5.4, the Company and
Parent, through their respective Boards of Directors, shall (i) recommend
approval of the matters described in Section 5.4(a) to be submitted to their
respective stockholders, (ii) not withdraw, withhold, modify, or change such

                                       A-35


recommendation in a manner adverse to the other party, (iii) not recommend or
declare advisable any Company Superior Proposal or Parent Superior Proposal, as
the case may be, and (iv) unless such recommendation has been withdrawn,
withheld, modified or changed as permitted by this Section 5.4(b), use their
reasonable best efforts to solicit the Company Requisite Vote (in the case of
the Company) and the Parent Requisite Vote (in the case of Parent). The Board of
Directors of the Company or Parent, as applicable (the "Withdrawing Party;" the
other party being the "Non-Withdrawing Party"), may at any time prior to
obtaining the Company Requisite Vote or Parent Requisite Vote, as applicable,
(1) withdraw, withhold, modify, or change, in a manner adverse to the
Non-Withdrawing Party, any approval or recommendation regarding this Agreement
or the transactions contemplated hereby or (2) recommend and declare advisable
any Company Superior Proposal or Parent Superior Proposal, as the case may be
(the actions set forth in clauses (1) and (2) being referred to herein as
"Adverse Actions"), if its Board of Directors determines in good faith after
consultation with its outside legal counsel that the failure to take the Adverse
Action in question would be inconsistent with its fiduciary obligations under
applicable law. After the Board of Directors has made a determination to take an
Adverse Action pursuant to the previous sentence but at least two business days
prior to taking such Adverse Action, the Board of Directors of the Withdrawing
Party shall give the Non-Withdrawing Party written notice of the Withdrawing
Party's intention to take such Adverse Action (including a reasonable
description of the circumstances related thereto) so as to allow the
Non-Withdrawing Party to propose a modification to the terms of the Merger or
this Agreement that would eliminate the need to take the Adverse Action.
Notwithstanding any Adverse Action taken by the Withdrawing Party, the
Non-Withdrawing Party shall have the option (the "Option"), exercisable in its
sole discretion within two business days of written notice of such Adverse
Action by the Withdrawing Party (which written notice shall be provided by the
Withdrawing Party to the Non-Withdrawing Party promptly, but in any event,
within 24 hours, of the Withdrawing Party taking such Adverse Action and shall
include a reasonable description of the circumstances related thereto), to cause
the Withdrawing Party to submit the matters to be voted on by such stockholders
(as contemplated hereby) to the stockholders of the Withdrawing Party at the
relevant stockholders meeting and, in connection with such submission,
communicate the circumstances under which the matters to be voted on by such
stockholders (as contemplated hereby) are being submitted to its stockholders.
If the Non-Withdrawing Party exercises the Option within the time permitted, the
Non-Withdrawing Party shall no longer be entitled to terminate this Agreement
under Section 7.3(b) or Section 7.4(b) below, as applicable. If the
Non-Withdrawing Party exercises the Option within the time permitted, the
Withdrawing Party shall use its reasonable best efforts, if so requested by the
Non-Withdrawing Party, to promptly furnish or cause to be furnished (in such
formats, including electronic formats, as the Non-Withdrawing Party or its
agents, advisors or attorneys may reasonably request) to the Non-Withdrawing
Party and its agents, advisors and attorneys, at the Non-Withdrawing Party's
expense, the most current, accurate and complete shareholders lists of the
Withdrawing Party, including non-objecting beneficial owner lists, as may b e
requested by the Non-Withdrawing Party or its agents, advisors or attorneys from
time to time so that the Non-Withdrawing Party can solicit proxies from the
Withdrawing Party's stockholders. If the Non-Withdrawing Party fails to exercise
the Option within the time permitted, the Withdrawing Party may terminate this
Agreement at any time after the expiration of the relevant two business day
period but prior to obtaining the Company Requisite Vote (if the Withdrawing
Party is the Company) or the Parent Requisite Vote (if the Withdrawing Party is
Parent) pursuant to Section 7.3(c) or Section 7.4(c) below, as applicable;
provided, however, that in the event that the Non-Withdrawing Party proposes to
the Withdrawing Party any modifications to the terms of the Merger or this
Agreement during such two business day period (the "Modified Terms"), the
Withdrawing Party shall not be permitted to terminate this Agreement pursuant to
Section 7.3(c) or Section 7.4(c) below, as applicable, unless and until the
Board of Directors of the Withdrawing Party (i) in good faith considers the
Modified Terms and (ii) makes a good faith determination, after consultation
with its outside legal counsel, that proceeding with a transaction with the
Non-Withdrawing Party reflecting the Modified Terms would be inconsistent with
its fiduciary obligations under applicable law. If the Non-Withdrawing Party
proposes Modified Terms to the Withdrawing Party pursuant to the previous
sentence which causes the Withdrawing Party's Board of Directors to reinstate
its recommendation regarding this Agreement and the transactions contemplated
hereby and to proceed with a transaction with the Non-
                                       A-36


Withdrawing Party, then in the event that subsequent to the acceptance by the
Withdrawing Party of the Modified Terms the Board of Directors of the
Withdrawing Party again either (i) withdraws, withholds, modifies, or changes,
in a manner adverse to the Non-Withdrawing Party, any approval or recommendation
regarding this Agreement or the transactions contemplated hereby or (ii)
recommends and declares advisable any Company Superior Proposal or Parent
Superior Proposal, as the case may be, then the Non-Withdrawing Party shall
again have the right to exercise the Option pursuant to the terms of this
Section 5.4(b).

     SECTION 5.5  Filings; Reasonable Best Efforts.

     (a) Subject to the terms and conditions herein provided, the Company and
Parent shall:

          (i) promptly (but in not more than 10 business days from the date
     hereof) make their respective filings under the HSR Act with respect to the
     Merger and thereafter shall promptly make any other required submissions
     under the HSR Act;

          (ii) use their reasonable best efforts to satisfy the conditions to
     closing in Article 6 (including, in the case of the Company, obtaining the
     opinion described in Section 6.2(b) and, in the case of Parent, obtaining
     the opinion described in Section 6.3(b)) as promptly as practicable and to
     cooperate with one another in (1) determining which filings are required to
     be made prior to the Effective Time with, and which consents, approvals,
     permits or authorizations are required to be obtained prior to the
     Effective Time from, governmental or regulatory authorities of the United
     States, the several states, and foreign jurisdictions in connection with
     the execution and delivery of this Agreement and the consummation of the
     Merger and the transactions contemplated hereby; and (2) timely making all
     such filings and timely seeking all such consents, approvals, permits or
     authorizations;

          (iii) promptly notify each other of any communication concerning this
     Agreement or the Merger to that party from any governmental authority and
     permit the other party to review in advance any proposed communication
     concerning this Agreement or the Merger to any governmental entity;

          (iv) not agree to participate in any meeting or discussion with any
     governmental authority in respect of any filings, investigation or other
     inquiry concerning this Agreement or the Merger unless it consults with the
     other party in advance and, to the extent permitted by such governmental
     authority, gives the other party the opportunity to attend and participate
     thereat;

          (v) furnish the other party with copies of all correspondence, filings
     and communications (and memoranda setting forth the substance thereof)
     between them and their affiliates and their respective representatives on
     the one hand, and any government or regulatory authority or members or
     their respective staffs on the other hand, with respect to this Agreement
     and the Merger; and

          (vi) furnish the other party with such necessary information and
     reasonable assistance as such other parties and their respective affiliates
     may reasonably request in connection with their preparation of necessary
     filings, registrations or submissions of information to any governmental or
     regulatory authorities, including any filings necessary or appropriate
     under the provisions of the HSR Act.

     (b) Without limiting Section 5.5(a), Parent and the Company shall:

          (i) each use its reasonable best efforts to avoid the entry of, or to
     have vacated or terminated, any decree, order or judgment that would
     restrain, prevent or delay the Closing, including defending through
     litigation on the merits any claim asserted in any court by any party; and

          (ii) each use reasonable best efforts to avoid or eliminate each and
     every impediment under any antitrust, competition or trade regulation law
     that may be asserted by any governmental entity with respect to the Merger
     so as to enable the Closing to occur as soon as reasonably possible (and in
     any event no later than 60 days following the termination of all applicable
     waiting periods under the HSR Act, unless the parties are in litigation
     with the government, in which case at the conclusion of such litigation).

                                       A-37


     (c) Neither Parent nor the Company shall, without the other party's prior
written consent, commit to any divestitures, licenses, hold separate
arrangements or similar matters, including covenants affecting business
operating practices (or allow its Subsidiaries to commit to any divestitures,
licenses, hold separate arrangements or similar matters) in connection with the
transactions contemplated under this Agreement, but the parties shall commit or
consent to, and shall use reasonable efforts to effect (and shall cause their
Subsidiaries to commit or consent to and use reasonable efforts to effect), any
such divestitures, licenses, hold separate arrangements or similar matters as
any governmental entity shall request if such divestitures, licenses, hold
separate arrangements or similar matters are required by any such governmental
entity as a condition to resolving such governmental entity's objections to the
Merger or obtaining its approval of the Merger and are contingent upon
consummation of the Merger; provided that, notwithstanding anything to the
contrary in this Section 5.5(c) or the remainder of this Agreement, neither
Parent, the Company nor any of their respective Subsidiaries shall be required
to agree (with respect to (x) Parent or its Subsidiaries or (y) the Company or
its Subsidiaries) to any divestitures, licenses, hold separate arrangements or
similar matters, including covenants affecting business operating practices, if
such divestitures, licenses, arrangements or similar matters, individually or in
the aggregate, would have or reasonably be expected to have a Parent Material
Adverse Effect or a Company Material Adverse Effect.

     SECTION 5.6  Inspection.  From the date hereof to the Effective Time, the
Company and Parent shall allow all designated officers, attorneys, accountants
and other representatives of the other party access at all reasonable times upon
reasonable notice to the records and files, correspondence, audits and
properties, as well as to all information relating to commitments, contracts,
titles and financial position, or otherwise pertaining to the business and
affairs of the Company and its Subsidiaries or Parent and its Subsidiaries,
including inspection of such properties; provided that no investigation pursuant
to this Section 5.6 shall affect any representation or warranty given by any
party hereunder, and provided further that notwithstanding the provision of
information or investigation by any party, no party shall be deemed to make any
representation or warranty except as expressly set forth in this Agreement.
Notwithstanding the foregoing, no party shall be required to provide any
information which it reasonably believes it may not provide to any other party
by reason of applicable law, rules or regulations, which that party reasonably
believes constitutes information protected by attorney/client privilege, or
which it is required to keep confidential by reason of contract or agreement
with third parties. The parties hereto will make reasonable and appropriate
substitute disclosure arrangements under circumstances in which the restrictions
of the preceding sentence apply. The Company and Parent agree that they will
not, and will cause their representatives not to, use any information obtained
pursuant to this Section 5.6 for any purpose unrelated to the consummation of
the transactions contemplated by this Agreement. All nonpublic information
obtained pursuant to this Section 5.6 shall be governed by the Confidentiality
Agreement dated October 25, 2002 between Parent and the Company (the
"Confidentiality Agreement").

     SECTION 5.7  Publicity.  The Company and Parent will consult with each
other and will mutually agree upon any press releases or public announcements
pertaining to this Agreement or the transactions contemplated hereby and shall
not issue any such press releases or make any such public announcements prior to
such consultation and agreement, except as may be required by applicable law or
by obligations pursuant to any listing agreement with any national securities
exchange, in which case the party proposing to issue such press release or make
such public announcement shall use its reasonable best efforts to consult in
good faith with the other party before issuing any such press releases or making
any such public announcements.

     SECTION 5.8  Registration Statement.

     (a) Each of Parent and the Company shall cooperate and as promptly as
practicable prepare, and Parent shall file with the SEC as soon as practicable,
a Registration Statement on Form S-4 under the Securities Act (the "Registration
Statement"), with respect to the Parent Common Stock issuable in the Merger. A
portion of the Registration Statement shall also serve as the joint proxy
statement with respect to the meetings of the stockholders of Parent and of the
Company in connection with the Merger (the "Proxy Statement/Prospectus"). The
respective parties will cause the Proxy Statement/Prospectus and the
Registration Statement to comply as to form in all material respects with the
applicable provisions of the
                                       A-38


Securities Act, the Exchange Act and the rules and regulations thereunder.
Parent shall use its reasonable best efforts, and the Company will cooperate
with Parent, to have the Registration Statement declared effective by the SEC as
promptly as practicable. Parent shall use its reasonable best efforts to obtain,
prior to the effective date of the Registration Statement, all necessary state
securities law or "Blue Sky" permits or approvals required to carry out the
transactions contemplated by this Agreement and will pay all expenses incident
thereto. Parent will advise the Company, promptly after it receives notice
thereof, of the time when the Registration Statement has become effective or any
supplement or amendment has been filed, the issuance of any stop order, the
suspension of the qualification of the Parent Common Stock issuable in
connection with the Merger for offering or sale in any jurisdiction, or any
request by the SEC for amendment of the Proxy Statement/ Prospectus or the
Registration Statement or comments thereon and responses thereto or requests by
the SEC for additional information.

     (b) Each of Parent and the Company will use its reasonable best efforts to
cause the Proxy Statement/Prospectus to be mailed to its stockholders as
promptly as practicable after the date hereof.

     (c) Each of Parent and the Company agrees that the information provided by
it for inclusion in the Proxy Statement/Prospectus and each amendment or
supplement thereto, at the time of mailing thereof and at the time of the
respective meetings of stockholders of Parent and of the Company, or, in the
case of information provided by it for inclusion in the Registration Statement
or any amendment or supplement thereto, at the time it is filed or becomes
effective, will not include an untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading.

     SECTION 5.9  Listing Application.  Parent shall use its reasonable best
efforts to cause the Parent Common Stock to be issued in the Merger to be
approved for listing on the AMEX prior to the Effective Time, subject to
official notice of issuance. Parent shall promptly prepare and submit to the
AMEX a supplemental listing application covering the shares of Parent Common
Stock issuable in the Merger and shares issuable pursuant to Assumed Options (as
defined below).

     SECTION 5.10  Intentionally Omitted.

     SECTION 5.11  Agreements of Affiliates.  Prior to the Effective Time, the
Company shall cause to be prepared and delivered to Parent a list identifying
all persons who, at the time of the meeting of the Company's stockholders
pursuant to Section 5.4, the Company believes may be deemed to be "affiliates"
of the Company, as that term is used in paragraphs (c) and (d) of Rule 145 under
the Securities Act (the "Rule 145 Affiliates"). Parent shall be entitled to
place restrictive legends on any shares of Parent Common Stock received by such
Rule 145 Affiliates. The Company shall use its reasonable best efforts to cause
each person who is identified as a Rule 145 Affiliate in such list to deliver to
Parent, at or prior to the Effective Time, a written agreement, in the form
attached hereto as Exhibit D.

     SECTION 5.12  Expenses.  Whether or not the Merger is consummated, all
costs and expenses incurred in connection with this Agreement and the
transactions contemplated hereby shall be paid by the party incurring such
expenses, except as expressly provided in Section 7.5.

     SECTION 5.13  Indemnification and Insurance.

     (a) From and after the Effective Time, Parent shall cause the Surviving
Corporation to indemnify, defend and hold harmless to the fullest extent
permitted under applicable law each person who is immediately prior to the
Effective Time, or has been at any time prior to the Effective Time, an officer
or director of the Company (or any Subsidiary or division thereof) and each
person who immediately prior to the effective time is serving or prior to the
Effective Time has served at the request of the Company as a director, officer,
trustee or fiduciary of another corporation, partnership, joint venture, trust,
pension or other employee benefit plan or enterprise (individually, an
"Indemnified Party" and, collectively, the "Indemnified Parties") against all
losses, claims, damages, liabilities, costs or expenses (including attorneys'
fees), judgments, fines, penalties and amounts paid in settlement in connection
with any claim, action, suit, proceeding or investigation arising out of or
pertaining to acts or omissions, or alleged acts or omissions, by them in their
capacities as such, whether commenced, asserted or claimed before or after the
                                       A-39


Effective Time. In the event of any such claim, action, suit, proceeding or
investigation (an "Action"), (i) Parent shall cause the Surviving Corporation to
pay, as incurred, the fees and expenses of counsel selected by the Indemnified
Party, which counsel shall be reasonably acceptable to Parent, in advance of the
final disposition of any such Action to the fullest extent permitted by
applicable law, and, if required, upon receipt of any undertaking required by
applicable law, and (ii) Parent will, and will cause the Surviving Corporation
to, cooperate in the defense of any such matter; provided, however, neither
Parent nor the Surviving Corporation shall be liable for any settlement effected
without its written consent (which consent shall not be unreasonably withheld or
delayed), and provided further that neither Parent nor the Surviving Corporation
shall be obligated pursuant to this Section 5.13(a) to pay the fees and
disbursements of more than one counsel for all Indemnified Parties in any single
Action, unless, in the good faith judgment of any of the Indemnified Parties,
there is or may be a conflict of interests between two or more of such
Indemnified Parties, in which case there may be separate counsel for each
similarly situated group.

     (b) The parties agree that the rights to indemnification hereunder,
including provisions relating to advances of expenses incurred in defense of any
action or suit, in the certificate of incorporation, bylaws and any
indemnification agreement of the Company and its Subsidiaries with respect to
matters occurring through the Effective Time, shall survive the Merger and shall
continue in full force and effect for a period of six years from the Effective
Time; provided, however, that all rights to indemnification and advancement of
expenses in respect of any Action pending or asserted or claim made within such
period shall continue until the disposition of such Action or resolution of such
claim.

     (c) For a period of six years after the Effective Time, the Surviving
Corporation shall maintain officers' and directors' liability insurance covering
the Indemnified Parties who are or at any time prior to the Effective Time were
covered by the Company's existing officers' and directors' liability insurance
("D&O Insurance") policies on terms substantially no less advantageous to the
Indemnified Parties than such existing insurance with respect to acts or
omissions, or alleged acts or omissions, prior to the Effective Time (whether
claims, actions or other proceedings relating thereto are commenced, asserted or
claimed before or after the Effective Time); provided that, after the Effective
Time, the Surviving Corporation shall not be required to pay annual premiums in
excess of 250% of the 2003 annual premium paid by the Company prior to the date
hereof (the amount of which premiums are set forth in the Company Disclosure
Letter) (the "Maximum Premium"), but in such case shall purchase as much
coverage as reasonably practicable for such amount. Parent shall have the right
to cause coverage to be extended under the Company's D&O Insurance by obtaining
a six-year "tail" policy on terms and conditions no less advantageous than the
Company's existing D&O Insurance, and such "tail" policy shall satisfy the
provisions of this Section 5.13(c).

     (d) The rights of each Indemnified Party hereunder shall be in addition to
any other rights such Indemnified Party may have under the certificate of
incorporation or bylaws of the Company or any of its Subsidiaries, under the
DGCL, or otherwise. The provisions of this Section 5.13 shall survive the
consummation of the Merger and expressly are intended to benefit each of the
Indemnified Parties.

     (e) In the event Parent or any of its successors or assigns (i)
consolidates with or merges into any other person and shall not be the
continuing or surviving corporation or entity in such consolidation or merger or
(ii) transfers all or substantially all of its properties and assets to any
person, then and in either such case, Parent shall cause proper provision to be
made so that the successors and assigns of Parent, as the case may be, shall
assume the obligations set forth in this Section 5.13.

     SECTION 5.14  Employee Benefits.

     (a) Parent hereby agrees to honor, and agrees to cause its Subsidiaries to
honor, all employee benefit plans, contracts, agreements and commitments of the
Company or any of its Subsidiaries maintained or entered into by the Company or
any of its Subsidiaries prior to the date hereof that apply to any current or
former employee or current or former director of the Company or any of its
Subsidiaries, including the executive change-in-control severance agreements
between the Company and certain of its key employees (copies of which executive
change-in-control severance agreements have been furnished to Parent);
                                       A-40


provided, however, that, except as otherwise expressly provided in this Section
5.14, Parent reserves the right to modify any such plan, contract, agreement or
commitment in accordance with its terms.

     (b) Notwithstanding the provisions of Section 5.14(a):

          (i) Parent and the Company agree that the consummation of the
     transaction contemplated by this Agreement shall constitute a "Change of
     Control" as that term is defined in the Ocean Energy, Inc. 2001 Change of
     Control Severance Plan (the "Company Severance Plan"), and that, to the
     extent required by Section 4.5 of the Company Severance Plan, such plan
     shall not be modified with respect to severance benefits payable and
     Welfare Benefit Coverages provided as a result of Involuntary Terminations
     occurring before the one-year anniversary of the Effective Time. The
     Company agrees that, prior to the Effective Time, it shall amend the
     Company Severance Plan to provide that a transfer between Parent and one of
     its Subsidiaries or between two of its Subsidiaries at or after the
     Effective Time shall not constitute a termination of employment resulting
     in eligibility for severance; provided that if the transfer results in a
     Change in Duties, any such transfer may be treated as a basis for
     Involuntary Termination to the extent provided by the terms of the Company
     Severance Plan, including the definitions of "Involuntary Termination" and
     "Change in Duties" (as in effect on December 1, 2002).

          (ii) Parent agrees that for the period beginning at the Effective Time
     and ending December 31, 2003 (or such later date determined by Parent), the
     Company and its Subsidiaries (and any successor entities to the Company or
     any of its Subsidiaries) shall maintain the medical, health, life, and
     disability insurance plans, and the deferred compensation and retirement
     plans, as in effect immediately prior to the Effective Time, and prior to
     January 1, 2004 shall not amend any such plan to reduce any benefit
     provided under any such plan. With respect to the Company's Retirement
     Savings Plan, Parent shall cause the Company to make an employer
     discretionary contribution for 2003 for the eligible participants at the
     same fraction of their eligible compensation as the Company's discretionary
     contributions made for 2001 and 2002.

          (iii) If, during calendar year 2004, the benefits applicable to
     officers and employees of the Company or its Subsidiaries (and any
     successor entities to the Company or any of its Subsidiaries) are
     materially modified then, for the remainder of calendar year 2004, Parent
     hereby agrees to, and agrees to cause its Subsidiaries to, provide to
     officers and employees of the Company and its Subsidiaries (and any
     successor entities to the Company or any of its Subsidiaries) who become or
     remain regular (full-time) employees of Parent or any of its Subsidiaries
     (including, without limitation, the Company and any successor entity to the
     Company for so long as it is a Subsidiary of Parent) employee benefits, no
     less favorable than those provided by Parent and its Subsidiaries to their
     similarly situated officers and employees.

          (iv) Each employee of the Company or its Subsidiaries (and any
     successor entities to the Company or any of its Subsidiaries) who becomes a
     participant in any employee benefit plan, program, policy, or arrangement
     of Parent or any of its Subsidiaries on or after the Effective Time shall
     be given credit under such plan, program, policy, or arrangement for all
     service with the Company, any of its Subsidiaries, any of their
     predecessors to the extent such predecessor employment was recognized by
     the Company or any of its Subsidiaries, and, if applicable, with Parent or
     any of its Subsidiaries, prior to becoming such a participant for purposes
     of eligibility, vesting and benefit determination; provided that this
     Section 5.14(b)(iv) shall not apply to the determination of accrual service
     under any defined benefit pension plan as defined in section 3(35) of ERISA
     (regardless of whether such plan is qualified under Code section 401(a)),
     and shall not apply to the determination of the right to receive, or the
     amount of, any retiree or other post-retirement medical service (except for
     COBRA medical continuation coverage as described in section 4980B of the
     Code).

          (v) At such time, if any, as Parent causes an employee of the Company
     or its Subsidiaries (and any successor entities to the Company or any of
     its Subsidiaries) to be covered under a group health plan maintained by
     Parent or one of its Subsidiaries (other than the group health plan
     maintained by
                                       A-41


     the Company at the Effective Time), Parent shall cause (A) such employee
     and his or her eligible dependents (including, without limitation, all such
     dependents of the employee covered immediately prior to such time under the
     Company's group health plan) to be credited under such Parent or Subsidiary
     group health plan, for the year during which such coverage under such group
     health plan begins, with any deductibles and copayments already incurred
     during such year under the group health plan of the Company (or successor
     entity to the Company), and (B) such Parent or Subsidiary group health plan
     to waive any preexisting condition restrictions to the extent necessary to
     provide immediate coverage (to the extent such preexisting condition
     restrictions have been waived, or would have been waived, under the
     Company's group health plan).

          (vi) Nothing in this Section 5.14(b) shall be construed to restrict
     the ability of Parent and its Subsidiaries (including, without limitation,
     the Company and any successor entity to the Company for so long as it is a
     Subsidiary of Parent) to modify or terminate any plan (at or after the
     Effective Time) with respect to persons employed at operations outside the
     United States.

          (vii) Nothing in this Section 5.14(b) shall be construed as a contract
     of employment, and this Section 5.14(b) shall not give any employee the
     right to be retained in the employ of Parent or any of its Subsidiaries.
     Nothing in this Section 5.14(b) shall be construed to require the provision
     of coverage or benefits to an employee following termination of employment
     except to the extent such coverage or benefits is otherwise required
     pursuant to the terms of the applicable plan or arrangement.

          (viii) Notwithstanding anything in this Section 5.14 to the contrary,
     (1) the Average Monthly Compensation used to determine the benefit of each
     member under the Company's Executive Supplemental Retirement Plan ("ESRP")
     shall not be less than such members' Average Monthly Compensation as of
     January 1, 2003, (2) each member shall receive credit, for purposes of
     vesting in his Accrued Benefit, for his service with Parent and its
     Subsidiaries (including the Company and its Subsidiaries) following the
     Effective Time, (3) no amendment may be made to the ESRP that would
     adversely affect the member's right to continued vesting under the ESRP
     based on his continued service with the Company and its Subsidiaries, and
     (4) if the ESRP is terminated, each member who is then an employee of the
     Parent and its Subsidiaries (including the Company and its Subsidiaries)
     automatically shall be 100% vested on such termination.

          (ix) The parties intend and agree that the employees of the Company
     and its Subsidiaries on the Closing Date are third party beneficiaries with
     respect to the provisions of this Section 5.14 that are applicable to such
     employee and shall be entitled to enforce such provisions against the
     parties.

     (c) Parent and the Company shall take such actions, including (with respect
to the Company) the amendment of the options ("Stock Options") to purchase
Company Common Shares, and the plans pursuant to which such options have been
issued, to permit Parent to assume, and Parent shall assume, effective at the
Effective Time, each Option Plan and each Stock Option that remains unexercised
in whole or in part as of the Effective Time and substitute shares of Parent
Common Stock for the Company Common Shares purchasable under each such assumed
option ("Assumed Option"), which assumption and substitution shall be effected
as follows:

          (i) the number of shares of Parent Common Stock purchasable under the
     Assumed Option shall be equal to 0.414 (to be adjusted appropriately if the
     Exchange Ratio is adjusted pursuant to Section 2.4) times the number of
     Company Common Shares underlying the Assumed Option (or that would be
     purchasable if the option was then vested and exercisable and with any
     fractional amount rounded to the next lowest share);

          (ii) the per share exercise price of such Assumed Option shall be an
     amount (with fractional amounts rounded to the next highest cent) equal to
     the per share exercise price of the Stock Option being assumed divided by
     0.414 (to be adjusted appropriately if the Exchange Ratio is adjusted
     pursuant to Section 2.4);

                                       A-42


          (iii) Parent will provide each holder of each Stock Option being
     assumed with a statement showing the converted number of shares, the
     exercise price, and the expiration date for each Assumed Option;

          (iv) for any individual whose service is terminated after the
     Effective Time and, in connection with such termination, such individual is
     eligible to receive severance benefits, such individual's non-qualified
     stock options that are exercisable on the date of such individual's
     termination shall continue to be exercisable during the one-year period
     following such termination; and

          (v) any other provisions of each Assumed Option shall remain in
     effect; provided, however, that in the case of any option to which Section
     421 of the Code applies by reason of the qualifications under Section 422
     or 423 of the Code, the exercise price, the number of shares purchasable
     pursuant to such option and the terms and conditions of exercise of such
     option shall comply with Section 424(a) of the Code.

     (d) Parent shall take all corporate action necessary to reserve for
issuance a sufficient number of shares of Parent Common Stock for delivery upon
exercise of the Assumed Options, and, as soon as practicable after the Effective
Time, Parent shall file a registration statement on Form S-8 (or other
appropriate form) with respect to the shares of Parent Common Stock subject to
the Assumed Options, and shall use its reasonable best efforts to maintain the
effectiveness of such registration statement for so long as any of the Assumed
Options remain outstanding.

     (e) Parent agrees that its Board of Directors (or the Compensation
Committee thereof) shall, at or prior to the Effective Time, adopt resolutions
specifically approving, for purposes of Rule 16b-3 under the Exchange Act, the
receipt, pursuant to this Section 5.14, of Assumed Options.

     SECTION 5.15  Reorganization.  From and after the date hereof and until the
Effective Time, none of Parent, the Company or any of their respective
Subsidiaries shall knowingly (i) take any action, or fail to take any reasonable
action, as a result of which the Merger would fail to qualify as a
reorganization within the meaning of section 368(a) of the Code or (ii) enter
into any contract, agreement, commitment or arrangement to take or fail to take
any such action. Following the Effective Time, Parent shall not knowingly take
any action or knowingly cause any action to be taken which would cause the
Merger to fail to qualify as a reorganization within the meaning of section
368(a) of the Code (and any comparable provisions of applicable state or local
law).

     SECTION 5.16  Dividends.  The Company shall coordinate with Parent
respecting the declaration, setting of record dates and payment dates of
dividends on the Company Common Shares so that holders of Company Common Shares
do not receive dividends on both Company Common Shares and Parent Common Stock
received in the Merger in respect of any calendar quarter or fail to receive a
dividend on Company Common Shares or Parent Common Stock received in the Merger
in respect of any calendar quarter.

                                   CONDITIONS

     SECTION 6.1  Conditions to Each Party's Obligation to Effect the
Merger.  The respective obligations of each party to effect the Merger shall be
subject to the fulfillment or waiver by mutual agreement of the parties at or
prior to the Closing Date of the following conditions:

          (a) (i) The Company Requisite Vote shall have been obtained and (ii)
     the Parent Requisite Vote shall have been obtained.

          (b) (i) The waiting period (and any extension thereof) applicable to
     the consummation of the Merger shall have expired or been terminated under
     the HSR Act and (ii) any mandatory waiting period or required consent under
     any applicable foreign competition or antitrust law or regulation shall
     have expired or been obtained except where the failure to observe such
     waiting period or obtain a

                                       A-43


     consent referred to in this clause (ii) would not reasonably be expected to
     delay or prevent the consummation of the Merger or have a material adverse
     effect on the expected benefits of the transactions contemplated by this
     Agreement to Parent.

          (c) None of the parties hereto shall be subject to any decree, order
     or injunction of a court of competent jurisdiction, U.S. or foreign, which
     prohibits the consummation of the Merger, and no statute, rule or
     regulation shall have been enacted by any governmental authority which
     prohibits or makes unlawful the consummation of the Merger.

          (d) The Registration Statement shall have become effective and no stop
     order with respect thereto shall be in effect and no proceedings for that
     purpose shall have been commenced or threatened by the SEC.

     as of the specified date), and Parent shall have received a certificate of
     the Company, executed on its behalf by its President or an Executive Vice
     President of the Company, dated the Closing Date, certifying to such
     effect.

          (b) Parent shall have received the opinion of Mayer, Brown, Rowe & Maw
     or other nationally recognized tax counsel, acting as counsel to Parent, in

the Effective Time, this Agreement may be terminated by the Company or Parent,
in either case by action of its Board of Directors, if:

          (a) the Merger shall not have been consummated by September 30, 2003;
     provided, however, that the right to terminate this Agreement pursuant to
     this clause (a) shall not be available to any party whose failure or whose
     affiliates' failure to perform or observe in any material respect any of
     its obligations under this Agreement in any manner shall have been the
     principal cause of, or resulted in, the failure of the Merger to occur on
     or before such date; or

          (b) the Company Requisite Vote shall not have been obtained at a
     meeting (including adjournments and postponements) of the Company's
     stockholders duly convened for the purpose of obtaining the Company
     Requisite Vote; or

          (c) the Parent Requisite Vote shall not have been obtained at a

     competent jurisdiction or United States federal or state or foreign
     governmental, regulatory or administrative agency or commission shall have
     issued an order, decree or ruling or taken any other action (including the
     enactment of any statute, rule, regulation, decree or executive order)
     permanently restraining, enjoining or otherwise

                                       A-45


     prohibiting the Merger and such order, decree, ruling or other action
     (including the enactment of any statute, rule, regulation, decree or
     executive order) shall have become final and non-appealable; provided,
     however, that the party seeking to terminate this Agreement pursuant to
     this clause (d) shall have complied with Section 5.5 and with respect to
     other matters not covered by Section 5.5 shall have used its reasonable
     best efforts to remove such injunction, order or decree.

     SECTION 7.3  Termination by the Company.  At any time prior to the
Effective Time, this Agreement may be terminated by the Company, by action of
its Board of Directors, if:

          (a) (i) there has been a breach by Parent or Merger Sub of any
     representation, warranty, covenant or agreement set forth in this Agreement
     or if any representation or warranty of Parent or Merger Sub shall have
     become untrue, in either case such that the conditions set forth in Section
     6.2(a) would not be satisfied and (ii) such breach is not curable, or, if
     curable, is not cured within 30 days after written notice of such breach is
     given to Parent by the Company; provided, however, that the right to
     terminate this Agreement pursuant to this Section 7.3(a) shall not be
     available to the Company if it, at such time, is in material breach of any
     representation, warranty, covenant or agreement set forth in this Agreement
     such that the conditions set forth in Section 6.3(a) shall not be
     satisfied;

          (b) prior to obtaining the Parent Requisite Vote, the Board of
     Directors of Parent shall have withdrawn, modified, withheld or changed, in
     a manner adverse to the Company, such Board's approval or recommendation of
     this Agreement or the Merger, or recommended a Parent Superior Proposal, or
     resolved to do any of the foregoing; provided that the Company may not
     exercise this right of termination if it exercises the Option or the
     circumstances giving rise to the right to terminate under this Section
     7.3(b) are no longer in effect because the parties are proceeding on
     Modified Terms; or

          (c) prior to obtaining the Company Requisite Vote, (i) the Company is
     the Withdrawing Party pursuant to Section 5.4(b), (ii) Parent had the right
     to exercise the Option and (iii) Parent did not exercise the Option within
     the time in which it had the right to do so (it being understood that the
     Company shall not have the right to terminate this Agreement pursuant to
     this Section 7.3(c) unless and until the Company shall have paid Parent any
     amounts due under Section 7.5(a)).

     SECTION 7.4  Termination by Parent.  At any time prior to the Effective
Time, this Agreement may be terminated by Parent, by action of its Board of
Directors, if:

          (a) (i) there has been a breach by the Company of any representation,
     warranty covenant or agreement set forth in this Agreement or if any
     representation or warranty of the Company shall have become untrue, in
     either case such that the conditions set forth in Section 6.3(a) would not
     be satisfied and (ii) such breach is not curable, or, if curable, is not
     cured within 30 days after written notice of such breach is given by Parent
     to the Company; provided, however, that the right to terminate this
     Agreement pursuant to this Section 7.4(a) shall not be available to Parent
     if it, at such time, is in material breach of any representation, warranty,
     covenant or agreement set forth in this Agreement such that the conditions
     set forth in Section 6.2(a) shall not be satisfied;

          (b) prior to obtaining the Company Requisite Vote, the Board of
     Directors of the Company shall have withdrawn, modified, withheld or
     changed, in a manner adverse to Parent, the Board's approval or
     recommendation of this Agreement or the Merger, or recommended a Company
     Superior Proposal, or resolved to do any of the foregoing; provided that
     Parent may not exercise this right of termination if it exercises the
     Option or the circumstances giving rise to the right to terminate under
     this Section 7.4(b) are no longer in effect because the parties are
     proceeding on Modified Terms; or

          (c) prior to obtaining the Parent Requisite Vote, (i) Parent is the

     Company any amounts due under Section 7.5(b)).
                                       A-46


     SECTION 7.5  Effect of Termination.

     (a) If this Agreement is terminated

          (i) by the Company or Parent, after the public announcement of a
     Company Acquisition Proposal or after Parent has exercised the Option,
     pursuant to Section 7.2(b);

          (ii) by Parent pursuant to Section 7.4(b); or

          (iii) by the Company pursuant to Section 7.3(c);

then the Company shall pay Parent the Company Termination Amount (as defined
below) and, in addition, reimburse Parent for all expenses incurred by Parent in
connection with this Agreement up to the Reimbursement Maximum Amount (as
defined below) prior to or upon termination of this Agreement. All payments
under this Section 7.5(a) shall be made in cash by wire transfer to an account
designated by Parent at the time of such termination (or, in the case of a
termination pursuant to Section 7.3(c), prior to such termination). The term
"Company Termination Amount" shall mean $139,000,000; provided, however, that
if, upon the termination of this Agreement by the Company or Parent pursuant to
Section 7.2(b) after the public announcement of a Company Acquisition Proposal,
the Board of Directors of the Company shall not have (x) withdrawn, withheld,
modified or changed, in a manner adverse to Parent, the Board's approval or
recommendation of this Agreement or the Merger, (y) recommended a Company
Superior Proposal or (z) resolved to do any of the foregoing, then the "Company
Termination Amount" shall mean $69,500,000 plus, if (x) the Company executes and
delivers an agreement with respect to any Company Acquisition (as defined below)
or (y) a Company Acquisition is consummated, in any such case within 12 months
from the date of termination, an additional $69,500,000 (which additional amount
shall be paid promptly by wire transfer to an account designated by Parent). If
the Board of Directors of the Company recommends the acceptance by the
stockholders of the Company of a third-party tender or exchange offer for
Company Common Shares, such recommendation shall have the same consequences for
purposes of this paragraph as though an agreement with respect to a Company
Acquisition had been executed and delivered. For purposes hereof, "Company
Acquisition" means (i) a consolidation, exchange of shares or merger of the
Company with any person, other than Parent or one of its Subsidiaries or any of
the Company's Subsidiaries, and, in the case of a merger, in which the Company
shall not be the continuing or surviving corporation, (ii) a merger of the
Company with a person, other than Parent or one of its Subsidiaries or any of
the Company's Subsidiaries, in which the Company shall be the continuing or
surviving corporation but the then outstanding Company Common Shares shall be
changed into or exchanged for stock or other securities of the Company or any
other person or cash or any other property or the Company Common Shares
outstanding immediately before such merger shall after such merger represent
less than 50% of the voting stock of the Company outstanding immediately after
the merger, (iii) the acquisition of beneficial ownership of 50% or more of the
voting stock of the Company by any person (as such term is used under Section
13(d) of the Exchange Act), or (iv) a sale, lease or other transfer of 50% or
more of the assets, net revenues or net operating income of the Company and its
Subsidiaries, taken as a whole, to any person, other than Parent or one of its
Subsidiaries or any of the Company's Subsidiaries. The term "Reimbursement
Maximum Amount" shall mean $10,000,000. In addition, the Company shall reimburse
Parent for all expenses incurred by Parent in connection with this Agreement up
to the Reimbursement Maximum Amount if this Agreement has been terminated
pursuant to Section 7.2(b) even if Parent is not entitled to any Company
Termination Amount under this Section 7.5(a). The Company acknowledges that the
agreements contained in this Section 7.5(a) are an integral part of the
transactions contemplated by this Agreement, and that, without these agreements,
Parent would not enter into this Agreement; accordingly, if the Company fails
promptly to pay any amount due pursuant to this Section 7.5(a), and, in order to
obtain such payment, Parent commences a suit which results in a judgment against
the Company for the payment set forth in this Section 7.5(a), the Company shall
pay to Parent its costs and expenses (including attorneys' fees) in connection
with such suit, together with interest on the Company Termination Amount and
other amounts to be reimbursed to Parent under this Section 7.5(a) from the date
payment was required to be made until the date of such payment at the prime rate
of JPMorgan Chase Bank in effect on the date such payment was required to be
made plus one

                                       A-47


percent (1%). If this Agreement is terminated pursuant to a provision that calls
for a payment to be made under this Section 7.5(a), it shall not be a defense to
the Company's obligation to pay hereunder that this Agreement could have been
terminated under a different provision or could have been terminated at an
earlier or later time.

     (b) If this Agreement is terminated

          (i) by the Company or Parent, after the public announcement of a
     Parent Acquisition Proposal or after the Company has exercised the Option,
     pursuant to Section 7.2(c);

          (ii) by the Company pursuant to Section 7.3(b); or

          (iii) by Parent pursuant to Section 7.4(c);

then Parent shall pay the Company the Parent Termination Amount (as defined
below) and, in addition, reimburse the Company for all expenses incurred by the
Company in connection with this Agreement up to the Reimbursement Maximum Amount
prior to or upon the termination of this Agreement. All payments under this
Section 7.5(b) shall be made in cash by wire transfer to an account designated
by the Company at the time of such termination (or, in the case of a termination
pursuant to Section 7.4(c), prior to such termination). The term "Parent
Termination Amount" shall mean $139,000,000; provided, however, that if, upon
termination of this Agreement by the Company or Parent pursuant to Section
7.2(c) after the public announcement of a Parent Acquisition Proposal, the Board
of Directors of Parent shall not have (x) withdrawn, withheld, modified or
changed, in a manner adverse to the Company, the Board's approval or
recommendation of this Agreement or the Merger, (y) recommended a Parent
Superior Proposal or (z) resolved to do any of the foregoing, then the "Parent
Termination Amount" shall mean $69,500,000 plus, if (x) Parent executes and
delivers an agreement with respect to any Parent Acquisition (as defined below)
or (y) a Parent Acquisition is consummated, in any such case, within 12 months
from the date of termination, an additional $69,500,000 (which additional amount
shall be paid promptly by wire transfer to an account designated by the
Company). If the Board of Directors of Parent recommends the acceptance by the
stockholders of Parent of a third-party tender or exchange offer for shares of
Parent Common Stock, such recommendation shall have the same consequences for
purposes of this paragraph as though an agreement with respect to a Parent
Acquisition had been executed and delivered. For purposes hereof, "Parent
Acquisition" means (i) a consolidation, exchange of shares or merger of Parent
with any person, other than the Company or one of its Subsidiaries or any of
Parent's Subsidiaries, and, in the case of a merger, in which Parent shall not
be the continuing or surviving corporation, (ii) a merger of Parent with a
person, other than the Company or one of its Subsidiaries or any of Parent's
Subsidiaries, in which Parent shall be the continuing or surviving corporation
but the then outstanding shares of Parent Common Stock shall be changed into or
exchanged for stock or other securities of Parent or any other person or cash or
any other property or the shares of Parent Common Stock outstanding immediately
before such merger shall after such merger represent less than 50% of the voting
stock of Parent outstanding immediately after the merger, (iii) the acquisition
of beneficial ownership of 50% or more of the voting stock of Parent by any
person (as such term is used under Section 13(d) of the Exchange Act), or (iv) a
sale, lease or other transfer of 50% or more of the assets, net revenues or net
operating income of Parent and its Subsidiaries, taken as a whole, to any
person, other than the Company or one of its Subsidiaries or any of Parent's
Subsidiaries. In addition, Parent shall reimburse the Company for all expenses
incurred by the Company in connection with this Agreement up to the
Reimbursement Maximum Amount if this Agreement has been terminated pursuant to
Section 7.2(c) even if the Company is not entitled to any Parent Termination
Amount under this Section 7.5(b). Parent acknowledges that the agreements
contained in this Section 7.5(b) are an integral part of the transactions
contemplated by this Agreement, and that, without these agreements, the Company
would not enter into this Agreement; accordingly, if Parent fails promptly to
pay any amount due pursuant to this Section 7.5(b), and, in order to obtain such
payment, the Company commences a suit which results in a judgment against Parent
for the payment set forth in this Section 7.5(b), Parent shall pay to the
Company its costs and expenses (including attorneys' fees) in connection with
such suit, together with interest on the Parent Termination Amount and other
amounts to be reimbursed to the

                                       A-48


Company under this Section 7.5(b) from the date payment was required to be made
until the date of such payment at the prime rate of JPMorgan Chase Bank in
effect on the date such payment was required to be made plus one percent (1%).
If this Agreement is terminated pursuant to a provision that calls for a payment
to be made under this Section 7.5(b), it shall not be a defense to Parent's
obligation to pay hereunder that this Agreement could have been terminated under
a different provision or could have been terminated at an earlier or later time.

     SECTION 7.6  Effect of Vote.  Any right to terminate this Agreement
provided under Sections 7.1, 7.2(a), 7.2(d), 7.3(a) or 7.4(a) hereunder shall be
effective notwithstanding whether the Company Requisite Vote or the Parent
Requisite Vote has been obtained. Any right to terminate this Agreement provided
under Sections 7.2(b) or 7.4(b) hereunder shall be effective notwithstanding
whether the Parent Requisite Vote has been obtained. Any right to terminate this
Agreement provided under Sections 7.2(c) or 7.3(b) hereunder shall be effective
notwithstanding whether the Company Requisite Vote has been obtained.

                                   ARTICLE 8

                               GENERAL PROVISIONS

     SECTION 8.1  Survival.  (a) In the event of termination of this Agreement
and the abandonment of the Merger pursuant to Article 7, all rights and
obligations of the parties hereto shall terminate, except the obligations of the

of Sections 8.3, 8.4, 8.6, 8.8, 8.9, 8.11, 8.12 and 8.13 and the Confidentiality
Agreement; provided that nothing herein shall relieve any party from any

covenants or agreements set forth in this Agreement and, subject to Section

the case of such a breach, at law or in equity, shall be preserved. The parties
hereto agree that, if this Agreement has been terminated, any remedy or amount
payable pursuant to Section 7.5 or Section 5.12 shall be the sole and exclusive
remedy of the party receiving payment thereunder unless the other party is in
material and willful breach of any of its covenants and agreements set forth in
this Agreement.

          (a) None of the representations, warranties and agreements in this
     Agreement or in any instrument delivered pursuant to this Agreement shall

Agreement are for the convenience of the parties only, and shall be given no

waiver by the party taking such action of compliance with any representations,
warranties, covenants or agreements contained in this Agreement. The waiver by
any party hereto of a breach of any provision hereunder shall not operate or be
construed as a waiver of any prior or subsequent breach of the same or any other

     SECTION 8.13  Obligation of Merger Sub.  Whenever this Agreement requires
Merger Sub (or its successors) to take any action prior to the Effective Time,
such requirement shall be deemed to include an undertaking on the part of Parent
to cause Merger Sub to take such action and a guarantee of the performance
thereof.

     SECTION 8.14  Extension; Waiver.  At any time prior to the Effective Time,
each party may, to the extent legally allowed, (a) extend the time for the

adopt a resolution or resolutions providing for the issuance of authorized but
unissued shares of Preferred Stock, which shares may be issued from time to time
in one or more series and in such amounts as may be determined by the Board of
Directors in such resolution or resolutions. The powers, voting powers,
designations, preferences, and relative, participating, optional or other
rights, if any, of each series of Preferred Stock and the qualifications,
limitations or restrictions, if any, of such powers, preferences and/or rights
(collectively the "Series Terms"), shall be such as are stated and expressed in
a resolution or resolutions providing for the creation or revision of such
Series Terms (a "Preferred Stock Series Resolution") adopted by the Board of
Directors (or a committee of the Board of Directors to which such responsibility
is specifically and

                                       A-54


lawfully delegated). The powers of the Board with respect to the Series Terms of
a particular series shall include, but not be limited to, determination of the
following:

          (i) The number of shares constituting that series and the distinctive
     designation of that series, or any increase or decrease (but not below the
     number of shares thereof then outstanding) in such number;

          (ii) The dividend rate or method of determining dividends on the
     shares of that series, any conditions upon which such dividends shall be
     payable, and the date or dates or the method for determining the date or
     dates upon which such dividends shall be payable, whether such dividends,
     if any, shall be cumulative, and, if so, the date or dates from which
     dividends payable on such shares shall accumulate, and the relative rights
     of priority, if any, of payment of dividends on shares of that series;

          (iii) The voting rights and powers, if any, of the holders of any
     series of Preferred Stock generally or with respect to any particular
     matter, which may be less than, equal to or greater than one vote per
     share, and which may, without limiting the generality of any other series
     of Preferred Stock or all series of Preferred Stock as a class, to elect
     one or more directors of the Corporation generally or under such specific
     circumstances and on such conditions, as shall be provided in the
     resolution or resolutions of the Board of Directors (or such committee of
     the Board of Directors, as the case may be) adopted pursuant hereto,
     including, without limitation, in the event there shall have been a default
     in the payment of dividends on or redemption of any one or more series of
     Preferred Stock;

          (iv) Whether that series shall have conversion or exchange privileges
     with respect to shares of any other class or classes of stock or of any
     other series of any class of stock, and, if so, the terms and conditions of
     such conversion or exchange, including provision for adjustment of the
     conversion or exchange rate upon occurrence of such events as the Board of
     Directors shall determine;

          (v) Whether the shares of that series shall be redeemable, and, if so,
     the price or prices and the terms and conditions of such redemption,
     including their relative rights of priority, if any, of redemption, the
     date or dates upon or after which they shall be redeemable, provisions
     regarding redemption notices, and the amount per share payable in case of
     redemption, which amount may vary under different conditions and at
     different redemption dates;

          (vi) Whether that series shall have a sinking fund for the redemption
     or repurchase of shares of that series, and, if so, the terms, conditions
     and amount of such sinking fund;

          (vii) The rights, if any, of the shares of that series in the event of
     voluntary or involuntary liquidation, dissolution, or winding up of the
     Corporation or in the event of any merger or consolidation of or sale of
     assets by the Corporation, and the relative rights of priority, if any, of
     payment of shares of that series;

          (viii) The conditions or restrictions upon the creation of
     indebtedness of the Corporation or upon the issuance of additional
     Preferred Stock or other capital stock ranking on a parity therewith, or
     prior thereto, with respect to dividends or distribution of assets upon
     liquidation;

          (ix) The conditions or restrictions with respect to the issuance of,
     payment of dividends upon, or the making of other distributions to, or the
     acquisition or redemption of, shares ranking junior to the Preferred Stock
     or to any series thereof with respect to dividends or distribution of
     assets upon liquidation; and

          (x) Any other designations, powers, preferences, and relative,
     participating, optional or other rights, including, without limitation, any
     qualifications, limitations, or restrictions thereof.

     Subject to the provisions of this Article IV, shares of one or more series
of Preferred Stock may be authorized or issued from time to time as shall be
determined by and for such consideration as shall be fixed by the Board of
Directors (or a designated committee thereof), in an aggregate amount not

                                       A-55


exceeding the total number of shares of Preferred Stock authorized by this
Certificate of Incorporation. The number of authorized shares of Preferred Stock
may be increased or decreased (but not below the number of shares thereof then
outstanding) by the affirmative vote of the holders of a majority of the
outstanding shares of Common Stock, without a vote of the holders of the
Preferred Stock, or of any series thereof, unless a vote of any such holder is
required pursuant to any Preferred Stock Series Resolution. Except as required
by law, holders of Preferred Stock shall not be entitled to receive notice of
any meeting of stockholders at which they are not entitled to vote. Except in
respect of series particulars fixed by the Board of Directors as permitted
hereby, all shares of Preferred Stock shall be of equal rank and shall be
identical. All shares of any one series of Preferred Stock so designated by the
Board of Directors shall be alike in every particular, except that shares of any
one series issued at different times may differ as to the dates from which
dividends thereon shall be cumulative.

          B.  Common Stock

             (i) Subject to the provisions of any Preferred Stock Series
        Resolution, the Board of Directors may, in its discretion, out of funds
        legally available for the payment of dividends and at such times and in
        such manner as determined by the Board of Directors, declare and pay
        dividends on the Common Stock of the Corporation.

             (ii) In the event of any liquidation, dissolution or winding up of
        the Corporation, whether voluntary or involuntary, after payment or
        provision for payment of the debts and other liabilities of the
        Corporation and payment or setting aside for payment of any preferential
        amount due to the holders of any other class or series of stock, the
        holders of the Common Stock shall be entitled to receive ratably any or
        all assets remaining to be paid or distributed.

             (iii) Subject to any special voting rights set forth in any
        Preferred Stock Series Resolution, the holders of the Common Stock of
        the Corporation shall be entitled at all meetings of stockholders to one
        vote for each share of such stock held by them. Except as may be
        provided in a Preferred Stock Series Resolution, the Common Stock shall
        have the exclusive right to vote for the election of directors and for
        all other purposes.

          C.  No Preemptive Rights

     No holder of shares of stock of the Corporation shall have any preemptive
or other rights, except as such rights are expressly provided by contract, to
purchase or subscribe for or receive any shares of any class, or series thereof,
of stock of the Corporation, whether now or hereafter authorized, or any
warrants, options, bonds, debentures or other securities convertible into,
exchangeable for or carrying any right to purchase any shares of any class, or
series thereof, of stock; but such additional shares of stock and such warrants,
options, bonds, debentures or other securities convertible into, exchangeable
for or carrying any right to purchase any shares of any class, or series
thereof, of stock may be issued or disposed of by the Board of Directors to such
persons, and on such terms and for such lawful consideration, as in its
discretion it shall deem advisable or as to which the Corporation shall have by
binding contract agreed.

          D.  Registered Owner

     The Corporation shall be entitled to treat the person in whose name any
share of its stock is registered as the owner thereof for all purposes and shall
not be bound to recognize any equitable or other claim to, or interest in, such
share on the part of any other person, whether or not the Corporation shall have
notice thereof, except as expressly provided by applicable law.

                                       A-56


                                   ARTICLE V

                               BOARD OF DIRECTORS

     The following provisions are inserted for the management of the business
and for the conduct of the affairs of the Corporation, and for further
definition, limitation and regulation of the powers of the Corporation and of
its directors and stockholders:

          The number and terms of the Board of Directors of the Corporation and
     the procedures to elect directors, to remove directors, and to fill
     vacancies in the Board of Directors shall be as follows:

             (i) Subject to the rights of holders of any series of Preferred
        Stock to elect additional directors under specified circumstances, the
        number of directors that shall constitute the whole Board of Directors
        shall from time to time be fixed exclusively by the Board of Directors
        by a resolution adopted by a majority of the whole Board of Directors
        serving at the time of that vote. No decrease in the number of directors
        shall have the effect of shortening the term of any incumbent director.
        Directors of the Corporation need not be elected by written ballot
        unless the Bylaws of the Corporation otherwise provide.

             (ii) Vacancies in the Board of Directors resulting from death,
        resignation, retirement, disqualification, removal from office, or other
        cause and newly-created directorships resulting from any increase in the
        authorized number of directors may only be filled by no less than a
        majority vote of the remaining directors then in office, though less
        than a quorum, or by the sole remaining director (but not by the
        stockholders except as required by law), and each director shall hold
        office until the first meeting of stockholders held after his election
        for the purpose of electing directors and until his successor is elected
        and qualified or until his earlier death, resignation, or removal from
        office.

     Notwithstanding the foregoing, whenever the holders of any one or more
series of Preferred Stock issued by the Corporation shall have the right, voting
separately by series, to elect one or more directors at an annual or special
meeting of stockholders, the election, term of office, filling of vacancies and
other features of such directorships shall be governed by the terms of such
series of Preferred Stock.

                                   ARTICLE VI

                                INDEMNIFICATION

     The Corporation shall indemnify, in accordance with and to the full extent
now or hereafter permitted by law, any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(including, without limitation, an action by or in the right of the
Corporation), by reason of his acting as a director or officer of the
Corporation (and the Corporation, in the discretion of the Board of Directors,
may so indemnify a person by reason of the fact that he is or was an employee or
agent of the Corporation or is or was serving at the request of the corporation
in any other capacity for or on behalf of the Corporation) against any liability
or expense actually and reasonably incurred by such person in respect thereof;
provided, however, the Corporation shall be required to indemnify an officer or
director in connection with an action, suit or proceeding initiated by such
person only if such action, suit or proceeding was authorized by the Board of
Directors of the Corporation. Such indemnification is not exclusive of any other
right to indemnification provided by law or otherwise. The right to
indemnification conferred by this Article VI shall be deemed to be a contract
between the Corporation and each person referred to herein.

                                  ARTICLE VII

                         LIMITED LIABILITY OF DIRECTORS

     No director shall be personally liable to the Corporation or its
stockholders for monetary damages for breach of fiduciary duty by such director
as a director, except for liability (a) for any breach of the
                                       A-57


director's duty of loyalty to the Corporation or its stockholders, (b) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (c) under Section 174 of the General Corporation Law
of the State of Delaware, or (d) for any transaction from which the director
derived an improper personal benefit. Any amendment or repeal of this Article
VII shall be prospective only, and neither the amendment, modification nor
repeal of this Article VII shall eliminate or reduce the effect of this Article
VII in respect of any matter occurring, or any cause of action, suit or claim
that, but for this Article VII would accrue or arise, prior to such amendment,
modification or repeal. If the General Corporation Law of the State of Delaware
hereafter is amended to authorize corporate action further eliminating or
limiting the liability of directors, then the liability of a director of the
Corporation, in addition to the limitation on personal liability provided
herein, shall be eliminated or limited to the fullest extent permitted by the
General Corporation Law of the State of Delaware, as so amended from time to
time.

                               THIRD AMENDMENT TO
                              EMPLOYMENT AGREEMENT

     WHEREAS, Ocean Energy, Inc. ("OEI") and James T. Hackett ("Executive") have
heretofore entered into an Employment Agreement (the "Agreement"), initially
effective as of September 16, 1998; and

     WHEREAS, the Agreement has been subsequently amended on two occasions and
OEI, Devon Energy Corporation ("Devon") and Executive desire to further amend
the Agreement in certain respects, contingent on, and effective upon, the
consummation of the transactions (the "Merger") contemplated by the Agreement
and Plan of Merger by and among Devon, Devon Newco Corporation, and OEI dated as
of February 23, 2003, as the same may be amended from time to time (the "Merger
Agreement");

     NOW, THEREFORE, the Agreement is amended as follows, effective as of the
"Effective Time" (which, for purposes of this Amendment, shall have the meaning
ascribed to it in the Merger Agreement):

          1. References to the "Company" in the Agreement shall mean Devon
     Energy Corporation.

          2. Paragraph 1.2 of the Agreement shall be amended to read as follows:

             "1.2  Positions.  Effective as of the Effective Time, the Company
        shall cause Executive to be appointed the President and Chief Operating
        Officer of the Company. The Company shall maintain Executive in such
        positions, or such other positions as the parties mutually may agree,
        for the full term of Executive's employment hereunder. The term
        "Effective Time" shall have the meaning ascribed to it in the Agreement
        and Plan of Merger by and among Devon Energy Corporation, Devon Newco
        Corporation, and Ocean Energy, Inc. dated as of February 23, 2003, as
        the same may be amended from time to time (the "Merger Agreement")."

          3. Article I is amended by adding thereto a new Paragraph 1.6, Office
     Location, to read as follows:

             "1.6  Office Location.  The Company's principal executive offices
        shall be maintained in the greater Oklahoma City, Oklahoma area. It is
        anticipated that Executive will regard Oklahoma City as the primary
        location of his office. Prior to the relocation of his residence to
        Oklahoma City, the Company shall provide Executive with appropriate
        airplane transportation between Oklahoma City and Houston, Texas, or
        promptly reimburse Executive for the cost thereof. In addition, prior to
        Executive's relocation to the greater Oklahoma City area (as provided
        below), the Company shall provide Executive with, or promptly reimburse
        Executive for the cost of, a temporary rented, furnished apartment or
        condominium in the greater Oklahoma City area and the use of an
        automobile while there (the "Temporary Benefits"). All utility expenses,
        gasoline, parking and other expenses incurred by Executive and
        reasonably related to the Temporary Benefits shall be paid by the
        Company. The Temporary Benefits provided Executive shall be of a nature
        and have a status appropriate for Executive's position with the Company.
        To the extent that the Company's provision or payment of any of these
        items is taxable compensation to Executive, the Company shall pay
        Executive, at such applicable times, an additional amount in cash such
        that the benefits are provided to Executive without any "tax cost,"
        whether federal, state or otherwise, to him.

             By May 1, 2004, Executive shall notify the Company whether he is
        relocating to the greater Oklahoma City area or exercising his right to
        terminate pursuant to paragraph 2.3(i). If Executive notifies the
        Company that he is relocating, he shall use his reasonable best efforts
        to so relocate by May 31, 2004, and if Executive has not relocated to
        the greater Oklahoma City area by June 30, 2004, the Company may
        terminate Executive's employment and such termination shall be deemed to
        have been for cause pursuant to paragraph 2.2(iii)."

                                       A-59


          4. Paragraph 2.1 is amended by adding a new sentence thereto to read
     as follows:

             "Notwithstanding the foregoing, the term of this Agreement shall
        not expire prior to the fifth anniversary of the Effective Time, unless
        sooner terminated pursuant to the other provisions hereof."

          5. Item (D) of Paragraph 2.3(i) is amended to read as follows:

             "(D) the Company's principal executive offices cease to be in the
        greater Oklahoma City area or Executive is required to work at an office
        other than the principal executive offices of the Company, excluding
        business travel reasonably consistent with Executive's past practice;"

          6. Paragraph 2.3 is further amended by adding thereto a new sentence
     to read as follows:

             "The Company and Executive agree that Executive may not terminate
        his employment pursuant to paragraph 2.3(i) due to a change in his
        duties, responsibilities, positions or principal place of employment
        based on the same as they existed immediately prior to the Effective
        Time; provided, however, the foregoing shall not prevent Executive from
        terminating pursuant to paragraph 2.3(i) based on any change from those
        duties, responsibilities, positions or principle place of employment as
        in effect immediately following the Effective Time; and provided,
        further, that upon not less than four weeks notice, Executive may in all
        events terminate his employment on May 1, 2004 and such termination
        shall be deemed to be for a reason encompassed by paragraph 2.3(i) for
        which there is no correction by the Company and upon such termination
        the Company shall provide Executive with the Termination Benefits."

          7. Paragraph 3.9(v) is amended by adding thereto the following:

             "Notwithstanding the foregoing or anything in the ESRP or
        Executive's Membership Agreement thereunder to the contrary, Executive
        may elect, at any time prior to the commencement of his benefit under
        the ESRP in an annuity form, to receive an amount equal to 95% of the
        Actuarial Equivalent (as such term is defined in the ESRP) of his then
        vested Accrued Benefit under the ESRP in a single lump sum. Upon such
        election, the non-vested portion, if any, of Executive's Accrued Benefit
        shall be forfeited. The Company shall cause the ESRP and Executive's
        Membership Agreement thereunder to be amended as necessary to reflect
        this Paragraph 3.9(v)."

          8. Notwithstanding anything herein to the contrary, the Company
     continues to have the right to terminate Executive's employment at any time
     pursuant to paragraph 2.2 and any such termination by the Company, other
     than pursuant to paragraph 2.2(iii) or (iv), shall entitle Executive to the
     Termination Benefits.

          9. As amended hereby, the Agreement is specifically ratified and
     reaffirmed. If the Merger Agreement is terminated without the consummation
     of the transactions contemplated thereby, this Amendment shall be null and
     void and of no effect.

                            [SIGNATURE PAGE FOLLOWS]

                       FORM OF COMPANY AFFILIATE'S LETTER

     This SHAREHOLDER AGREEMENT, dated as of           , 2003 (this "Agreement")
is among Devon Energy Corporation, a Delaware corporation ("Parent"), and the
undersigned shareholder ("Shareholder") of Ocean Energy, Inc., a Delaware
corporation (the "Company"). Capitalized terms not otherwise defined in this
Agreement have the meanings ascribed to them in the Merger Agreement.

                                    RECITALS

     A.  Parent, Devon NewCo Corporation, a Delaware corporation and a wholly
owned subsidiary of Parent ("Merger Sub"), and the Company have entered into an
Agreement and Plan of Merger, dated as of February 23, 2003 (the "Merger
Agreement"), pursuant to which Merger Sub will merge (the "Merger") with and
into the Company, with the Company surviving the Merger.

     B.  Pursuant to the Merger Agreement, at the Effective Time, outstanding
Company Common Shares will be converted into shares of Parent Common Stock;

     C.  The execution and delivery of this Agreement by Shareholder is a
material inducement to Parent to enter into the Merger Agreement; and

     D.  Shareholder has been advised that Shareholder may be deemed to be an
"affiliate" of the Company, as such term is used (i) for purposes of paragraphs
(c) and (d) of Rule 145 of the Securities and Exchange Commission (the
"Commission") under the Securities Act of 1933, as amended (the "Act").

     NOW, THEREFORE, intending to be legally bound, the parties agree as
follows:

          1.  Acknowledgments by Shareholder.  Shareholder acknowledges and
     understands that the representations, warranties and covenants made by
     Shareholder set forth in this Agreement will be relied upon by Parent, the
     Company, and their respective affiliates and counsel, and that substantial
     losses and damages may be incurred by such persons if Shareholder's
     representations, warranties or covenants are breached. Shareholder has
     carefully read this Agreement and the Merger Agreement and has consulted
     with such legal counsel and financial advisers as Shareholder has deemed
     appropriate in connection with the execution of this Agreement.

          2.  Compliance with Rule 145 and the Act.

             (a) Shareholder has been advised that (i) the issuance of shares of
        Parent Common Stock in connection with the Merger is expected to be
        effected pursuant to a Registration Statement filed by Parent on Form
        S-4, and the resale of such shares will be subject to the restrictions
        set forth in Rule 145 under the Act unless such shares are otherwise
        transferred pursuant to an effective registration statement under the
        Act or an appropriate exemption from registration, and (ii) Shareholder
        may be deemed to be an affiliate of the Company. Shareholder accordingly
        agrees not to sell, pledge, transfer or otherwise dispose of any shares
        of Parent Common Stock issued to Shareholder in the Merger, unless (i)
        such sale, pledge, transfer or other disposition is made in conformity
        with the requirements of Rule 145 under the Act, (ii) such sale, pledge,
        transfer or other disposition is made pursuant to an effective
        registration statement under the Act, or (iii) Shareholder delivers to
        Parent a written opinion of counsel, in form and substance reasonably
        acceptable to Parent to the effect that such sale, pledge, transfer or
        other disposition is otherwise exempt from registration under the Act.

             (b) Parent will give stop transfer instructions to its transfer
        agent with respect to any Parent Common Stock received by Shareholder
        pursuant to the Merger and there will be placed on the

                                       A-64


        certificates representing such Parent Common Stock, or any substitutions
        therefor, legends stating in substance:

             "THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED PURSUANT TO
        A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF
        1933 APPLIES, AND MAY ONLY BE TRANSFERRED IN CONFORMITY WITH RULE 145,
        PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT, OR IN ACCORDANCE WITH A
        WRITTEN OPINION OF COUNSEL, REASONABLY ACCEPTABLE TO THE ISSUER, IN FORM
        AND SUBSTANCE TO THE EFFECT THAT SUCH TRANSFER IS EXEMPT FROM
        REGISTRATION UNDER THE SECURITIES ACT OF 1933."

The legend set forth above shall be removed (by delivery of a substitute
certificate without such legend), and Parent shall so instruct its transfer
agent, if a registration statement respecting the sale of the shares has been
declared effective under the Act or if Shareholder delivers to Parent (i)
satisfactory written evidence that the shares have been sold in compliance with
Rule 145 (in which case, the substitute certificate will be issued in the name
of the transferee), or (ii) an opinion of counsel, in form and substance
reasonably acceptable to Parent to the effect that sale of the shares by the
holder thereof is no longer subject to Rule 145.

          3.  Miscellaneous.

             (a) This Agreement may be executed in one or more counterparts,
        each of which shall be deemed an original, but all of which together
        shall constitute one and the same document. Delivery of an executed
        counterpart of this Agreement by facsimile shall be effective to the
        fullest extent permitted by applicable law.

             (b) This Agreement shall be enforceable by, and shall inure to the
        benefit of and be binding upon, the parties and their respective
        successors and assigns. As used in this Agreement, the term "successors
        and assigns" means, where the context to permits, heirs, executors,
        administrators, trustees and successor trustees, and personal and other
        representatives.

             (c) This Agreement shall be deemed to be made in and in all
        respects shall be interpreted, construed and governed by and in
        accordance with the laws of the State of Delaware. The parties
        irrevocably and unconditionally consent to submit to the exclusive
        jurisdiction of the courts of the State of Delaware and of the United
        States of America, in either case located in Wilmington, Delaware (the
        "Delaware Courts") for any litigation arising out of or relating to this
        Agreement and the transactions contemplated by this Agreement (and agree
        not to commence any litigation relating thereto except in such Delaware
        Courts), waive any objection to the laying of venue of any such
        litigation in the Delaware Courts and agree not to plead or claim in any
        Delaware Court that such litigation brought therein has been brought in
        an inconvenient forum.

             (d) If any term, provision, covenant, or restriction contained in
        this Agreement is held by a court or a federal or state regulatory
        agency of competent jurisdiction to be invalid, void, or unenforceable,
        the remainder of the terms, provisions, covenants, and restrictions
        contained in this Agreement shall remain in full force and effect, and
        shall in no way be affected, impaired, or invalidated.

             (e) Counsel to the parties to the Merger Agreement shall be
        entitled to rely upon this Agreement as needed.

             (f) This Agreement shall not be modified or amended, or any right
        waived or any obligations excused, except by a written agreement signed
        by both parties.

             (g) Notwithstanding any other provision contained in this
        Agreement, this Agreement and all obligations under this Agreement shall

February 23, 2003

Board of Directors
Ocean Energy, Inc.
1001 Fannin Street, Suite 1600
Houston, Texas 77002-6794

Lady and Gentlemen:

     Deutsche Bank Securities Inc. ("Deutsche Bank") has acted as financial
advisor to Ocean Energy, Inc. ("Ocean" or the "Company") in connection with the
proposed combination of Ocean and Devon Energy Corporation ("Devon") pursuant to
the Agreement and Plan of Merger, dated as of February 23, 2003, among Ocean,
Devon and Devon Merger Sub, a direct wholly owned subsidiary of Devon ("Devon
Merger Sub") (the "Merger Agreement"), which provides, among other things, for
the merger of Devon Merger Sub with and into Ocean (the "Transaction"), as a
result of which Ocean will become a wholly owned subsidiary of Devon. As set
forth more fully in the Merger Agreement, as a result of the Transaction, each
share of the Common Stock, par value $0.10 per share, of the Company ("Company
Common Stock") not owned directly or indirectly by Devon or Ocean and not held
on behalf of third parties will be converted into the right to receive 0.414
shares (the "Exchange Ratio") of Common Stock, par value $0.10 per share, of
Devon ("Devon Common Stock"). The terms and conditions of the Transaction are
more fully set forth in the Merger Agreement.

     You have requested Deutsche Bank's opinion, as investment bankers, as to
the fairness, from a financial point of view, to the holders of the Company
Common Stock (other than Devon and its subsidiaries) of the Exchange Ratio.

     In connection with Deutsche Bank's role as financial advisor to Ocean, and
in arriving at its opinion, Deutsche Bank has reviewed certain publicly
available financial and other information concerning the Company and Devon and
certain internal analyses and other information furnished to it by the Company
and Devon. Deutsche Bank has also held discussions with members of the senior
managements of Ocean and Devon regarding the businesses and prospects of their
respective companies and the joint prospects of a combined company. In addition,
Deutsche Bank has (i) reviewed the reported prices and trading activity for
Ocean Common Stock and Devon Common Stock, (ii) compared certain financial and
stock market information for the Company and Devon with similar information for
certain other companies whose securities are publicly traded, (iii) reviewed the
financial terms of certain recent business combinations which it deemed
comparable in whole or in part, (iv) reviewed the terms of the Merger Agreement
and certain related documents, and (v) performed such other studies and analyses
and considered such other factors as it deemed appropriate.

     Deutsche Bank has not assumed responsibility for independent verification
of, and has not independently verified, any information, whether publicly
available or furnished to it, concerning Ocean or Devon, including, without
limitation, any financial information, forecasts or projections considered in
connection with the rendering of its opinion. Accordingly, for purposes of its
opinion, Deutsche Bank has assumed and relied upon the accuracy and completeness
of all such information and Deutsche Bank has

                                       B-1


                                                            (DEUTSCHE BANK LOGO)

not conducted a physical inspection of any of the properties or assets, and has
not prepared or obtained any independent evaluation or appraisal of any of the
assets or liabilities, of Ocean or Devon. With respect to the financial
forecasts and projections, including the analyses and forecasts of certain cost
savings, operating efficiencies, revenue effects and financial synergies
expected by Ocean and Devon to be achieved as a result of the Transaction
(collectively, the "Synergies"), made available to Deutsche Bank and used in its
analyses, Deutsche Bank has assumed that they have been reasonably prepared on
bases reflecting the best currently available estimates and judgments of the
management of Ocean or Devon, as the case may be, as to the matters covered
thereby. In rendering its opinion, Deutsche Bank expresses no view as to the
reasonableness of such forecasts and projections, including the Synergies, or
the assumptions on which they are based. Deutsche Bank's opinion is necessarily
based upon economic, market and other conditions as in effect on, and the
information made available to it as of, the date hereof.

     For purposes of rendering its opinion, Deutsche Bank has assumed that, in
all respects material to its analysis, the representations and warranties of
Ocean, Devon and Devon Merger Sub contained in the Merger Agreement are true and
correct, Ocean, Devon and Devon Merger Sub will each perform all of the
covenants and agreements to be performed by it under the Merger Agreement and
all conditions to the obligations of each of Ocean, Devon and Devon Merger Sub
to consummate the Transaction will be satisfied without any waiver thereof.
Deutsche Bank has also assumed that all material governmental, regulatory or
other approvals and consents required in connection with the consummation of the
Transaction will be obtained and that in connection with obtaining any necessary
governmental, regulatory or other approvals and consents, or any amendments,
modifications or waivers to any agreements, instruments or orders to which
either Ocean or Devon is a party or is subject or by which it is bound, no
limitations, restrictions or conditions will be imposed or amendments,
modifications or waivers made that would have a material adverse effect on Ocean
or Devon or materially reduce the contemplated benefits of the Transaction to
Ocean or the holders of the Company Common Stock. In addition, you have informed
Deutsche Bank, and accordingly for purposes of rendering its opinion Deutsche
Bank has assumed, that the Transaction will be tax-free to each of Ocean and
Devon and their respective stockholders. In arriving at this opinion, Deutsche
Bank analyzed the Transaction as a strategic business combination not involving
a sale of control of Ocean. Deutsche Bank was not authorized by Ocean or its
Board of Directors to solicit, and did not solicit, third-party indications of
interest with respect to the acquisition of all or any part of Ocean or any
other extraordinary transaction involving Ocean.

     Deutsche Bank does not express any opinion as to the price or range of
prices at which the Company Common Stock or the Devon Common Stock may trade
subsequent to the announcement of the Transaction or as to the price or range of
prices at which the Devon Common Stock may trade subsequent to the consummation
of the Transaction.

     This opinion is addressed to, and for the use and benefit of, the Board of
Directors of Ocean and is not a recommendation to the stockholders of Ocean to
approve the Transaction. This opinion is limited to the fairness, from a
financial point of view, to the holders of the Company Common Stock (other than
Devon and its subsidiaries) of the Exchange Ratio, and Deutsche Bank expresses
no opinion as to the merits of the underlying decision by Ocean to engage in the
Transaction.

     Deutsche Bank will be paid a fee for its services as financial advisor to
Ocean in connection with the Transaction, all of which is contingent upon
consummation of the Transaction. We are an affiliate of Deutsche Bank AG
(together with its affiliates, the "DB Group"). One or more members of the DB
Group have, from time to time, provided investment banking, commercial banking
(including extension of credit) and other financial services to Ocean and Devon
or their affiliates for which it has received compensation. In the ordinary
course of business, members of the DB Group may actively trade in the
                                       B-2

securities and other instruments and obligations of Ocean and Devon for their
own accounts and for the accounts of their customers. Accordingly, the DB Group
may at any time hold a long or short position in such securities, instruments
and obligations.

     Based upon and subject to the foregoing, it is Deutsche Bank's opinion as
of the date hereof as investment bankers that the Exchange Ratio is fair, from a
financial point of view, to the holders of the Company Common Stock (other than
Devon and its subsidiaries).

                                          Very truly yours,

(MORGAN STANLEY LETTERHEAD)

                                                               February 23, 2003

Board of Directors
Devon Energy Corporation
20 North Broadway, Suite 1500
Oklahoma City, Oklahoma 73103-8260

Members of the Board:

     We understand that Ocean Energy, Inc. ("Ocean" or the "Company"), Devon
Energy Corporation ("Devon") and Devon NewCo Corporation, a wholly owned
subsidiary of Devon ("Merger Sub"), propose to enter into an Agreement and Plan
of Merger substantially in the form of the draft dated February 23, 2003 (the
"Merger Agreement"), which provides for, among other things, the merger (the
"Merger") of Merger Sub with and into Ocean. Pursuant to the Merger, Ocean will
become a wholly owned subsidiary of Devon, and each issued and outstanding share
of common stock, par value $0.10 per share, of Ocean (the "Ocean Common Stock"),
other than shares of Ocean Common Stock held in treasury or owned by Devon or
any subsidiary of Devon or Ocean, will be converted into 0.414 shares (the
"Exchange Ratio") of common stock, par value $0.10 per share, of Devon (the
"Devon Common Stock"). We also note that each share of Series B Preferred Stock,
par value $1.00 per share, of Ocean (the "Ocean Preferred Stock") shall remain
outstanding upon consummation of the Merger, subject to any shares to which
dissenters' rights have been perfected. The terms and conditions of the Merger
are more fully set forth in the Merger Agreement.

     You have asked for our opinion as to whether the Exchange Ratio pursuant to
the Merger Agreement is fair from a financial point of view to Devon.

     For purposes of the opinion set forth herein, we have:

          (i) reviewed certain publicly available financial statements and other
     information of the Company and Devon, respectively;

          (ii) reviewed certain internal financial statements and other
     financial and operating data, including internal oil and gas reserve
     estimates, concerning the Company and Devon prepared by the managements of
     the Company and Devon, respectively;

          (iii) reviewed certain financial forecasts prepared by the managements
     of the Company and Devon, respectively;

          (iv) discussed the past and current operations and financial condition
     and the prospects of the Company, including information relating to certain
     strategic, financial and operational benefits anticipated from the Merger,
     with senior executives of the Company;

          (v) discussed the past and current operations and financial condition
     and the prospects of Devon, including information relating to certain
     strategic, financial and operational benefits anticipated from the Merger,
     with senior executives of Devon;

                                       C-1


          (vi) reviewed the pro forma impact of the Merger on Devon's earnings
     per share, cash flow, oil and gas reserves and production, consolidated
     capitalization and financial ratios;

          (vii) reviewed the reported prices and trading activity for the Ocean
     Common Stock and the Devon Common Stock;

          (viii) compared the financial performance of the Company and Devon and
     the prices and trading activity of the Ocean Common Stock and Devon Common
     Stock with that of certain other publicly-traded companies, comparable with
     the Company and Devon, respectively, and their securities;

          (ix) reviewed certain reserve reports prepared by Devon and Devon's
     independent reserve engineers;

          (x) reviewed certain reserve reports prepared by the Company and the
     Company's independent reserve engineers;

          (xi) reviewed the financial terms, to the extent publicly available,
     of certain comparable business combination transactions deemed relevant;

          (xii) participated in discussions and negotiations among
     representatives of the Company and Devon and their financial and legal
     advisors;

          (xiii) reviewed the Merger Agreement and certain related documents;
     and

          (xiv) performed such other analyses and considered such other factors
     as we have deemed appropriate.

     We have assumed and relied upon, without independent verification, the
accuracy and completeness of the information reviewed by us for the purposes of
this opinion. With respect to the financial forecasts, including information
relating to certain strategic, financial and operational benefits anticipated
from the Merger, we have assumed that they have been reasonably prepared on
bases reflecting the best currently available estimates and judgments of the
future financial performance of the Company and Devon, respectively. We have not
made any independent valuation or appraisal of the assets or liabilities of the
Company or Devon; nor have we been furnished with any such appraisals. With
respect to the reserve estimates and reports referred to in (ii), (vi), (ix) and
(x) above, we are not experts in the engineering evaluation of oil and gas
properties and, with your consent, we have relied, without independent
verification, solely upon the internal reserve estimates of the Company and
Devon, respectively. In addition, we have assumed that the Merger will be
consummated in accordance with the terms set forth in the Merger Agreement,
including, among other things, that the Merger will be treated as a tax-free
reorganization pursuant to the Internal Revenue Code of 1986. Our opinion is
necessarily based on financial, economic, market and other conditions as in
effect on, and the information made available to us as of, the date hereof.

     We have been retained to provide a financial opinion to the Board of
Directors of Devon in connection with this transaction and will receive a fee
for our services. In the past, Morgan Stanley & Co. Incorporated and its
affiliates have provided financial advisory and financing services for Devon and
have received fees for the rendering of these services.

     We are expressing no opinion herein as to the prices at which the Ocean
Common Stock or Devon Common Stock will trade at any time. In addition, Morgan
Stanley expresses no opinion or recommendation as to how the holders of Devon
Common Stock should vote at the shareholders' meeting held in connection with
the Merger.

     It is understood that this letter is for the information of the Board of
Directors of Devon only and may not be used for any other purpose without our
prior written consent, except that this opinion may be included in its entirety,
if required, in any filing of a proxy or a registration statement with the
Securities and Exchange Commission in connection with the Merger and the related
prospectus and proxy statement to be sent to shareholders.
                                       C-2


     Based upon and subject to the foregoing, we are of the opinion on the date
hereof that the Exchange Ratio pursuant to the Merger Agreement is fair from a
financial point of view to Devon.

                                          Very truly yours,

                                          MORGAN STANLEY & CO. INCORPORATED

DELAWARE GENERAL CORPORATION LAW -- SECTION 262

                                APPRAISAL RIGHTS

     (a) Any stockholder of a corporation of this State who holds shares of
stock on the date of the making of a demand pursuant to subsection (d) of this
section with respect to such shares, who continuously holds such shares through
the effective date of the merger or consolidation, who has otherwise complied
with subsection (d) of this section and who has neither voted in favor of the
merger or consolidation nor consented thereto in writing pursuant to sec. 228 of
this title shall be entitled to an appraisal by the Court of Chancery of the
fair value of the stockholder's shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the word "stockholder" means a holder of record of stock in a stock corporation
and also a member of record of a nonstock corporation; the words "stock" and
"share" mean and include what is ordinarily meant by those words and also
membership or membership interest of a member of a nonstock corporation; and the
words "depository receipt" mean a receipt or other instrument issued by a
depository representing an interest in one or more shares, or fractions thereof,
solely of stock of a corporation, which stock is deposited with the depository.

     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to sec. 251 (other than a merger effected pursuant to
sec. 251(g) of this title), sec. 252, sec. 254, sec. 257, sec. 258, sec. 263 or
sec. 264 of this title:

          (1) Provided, however, that no appraisal rights under this section
     shall be available for the shares of any class or series of stock, which
     stock, or depository receipts in respect thereof, at the record date fixed
     to determine the stockholders entitled to receive notice of and to vote at
     the meeting of stockholders to act upon the agreement of merger or
     consolidation, were either (i) listed on a national securities exchange or
     designated as a national market system security on an interdealer quotation
     system by the National Association of Securities Dealers, Inc. or (ii) held
     of record by more than 2,000 holders; and further provided that no
     appraisal rights shall be available for any shares of stock of the
     constituent corporation surviving a merger if the merger did not require
     for its approval the vote of the stockholders of the surviving corporation
     as provided in subsection (f) of sec. 251 of this title.

          (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
     under this section shall be available for the shares of any class or series
     of stock of a constituent corporation if the holders thereof are required
     by the terms of an agreement of merger or consolidation pursuant to
     sec. sec. 251, 252, 254, 257, 258, 263 and 264 of this title to accept for
     such stock anything except:

             a. Shares of stock of the corporation surviving or resulting from
        such merger or consolidation, or depository receipts in respect thereof;

             b. Shares of stock of any other corporation, or depository receipts
        in respect thereof, which shares of stock (or depository receipts in
        respect thereof) or depository receipts at the effective date of the
        merger or consolidation will be either listed on a national securities
        exchange or designated as a national market system security on an
        interdealer quotation system by the National Association of Securities
        Dealers, Inc. or held of record by more than 2,000 holders;

             c. Cash in lieu of fractional shares or fractional depository
        receipts described in the foregoing subparagraphs a. and b. of this
        paragraph; or

             d. Any combination of the shares of stock, depository receipts and
        cash in lieu of fractional shares or fractional depository receipts
        described in the foregoing subparagraphs a., b. and c. of this
        paragraph.

                                       D-1


          (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger effected under sec. 253 of this title is not owned by the
     parent corporation immediately prior to the merger, appraisal rights shall
     be available for the shares of the subsidiary Delaware corporation.

     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

     (d) Appraisal rights shall be perfected as follows:

          (1) If a proposed merger or consolidation for which appraisal rights
     are provided under this section is to be submitted for approval at a
     meeting of stockholders, the corporation, not less than 20 days prior to
     the meeting, shall notify each of its stockholders who was such on the
     record date for such meeting with respect to shares for which appraisal
     rights are available pursuant to subsection (b) or (c) hereof that
     appraisal rights are available for any or all of the shares of the
     constituent corporations, and shall include in such notice a copy of this
     section. Each stockholder electing to demand the appraisal of such
     stockholder's shares shall deliver to the corporation, before the taking of
     the vote on the merger or consolidation, a written demand for appraisal of
     such stockholder's shares. Such demand will be sufficient if it reasonably
     informs the corporation of the identity of the stockholder and that the
     stockholder intends thereby to demand the appraisal of such stockholder's
     shares. A proxy or vote against the merger or consolidation shall not
     constitute such a demand. A stockholder electing to take such action must
     do so by a separate written demand as herein provided. Within 10 days after
     the effective date of such merger or consolidation, the surviving or
     resulting corporation shall notify each stockholder of each constituent
     corporation who has complied with this subsection and has not voted in
     favor of or consented to the merger or consolidation of the date that the
     merger or consolidation has become effective; or

          (2) If the merger or consolidation was approved pursuant to sec. 228
     or sec. 253 of this title, then either a constituent corporation before the
     effective date of the merger or consolidation or the surviving or resulting
     corporation within 10 days thereafter shall notify each of the holders of
     any class or series of stock of such constituent corporation who are
     entitled to appraisal rights of the approval of the merger or consolidation
     and that appraisal rights are available for any or all shares of such class
     or series of stock of such constituent corporation, and shall include in
     such notice a copy of this section. Such notice may, and, if given on or
     after the effective date of the merger or consolidation, shall, also notify
     such stockholders of the effective date of the merger or consolidation. Any
     stockholder entitled to appraisal rights may, within 20 days after the date
     of mailing of such notice, demand in writing from the surviving or
     resulting corporation the appraisal of such holder's shares. Such demand
     will be sufficient if it reasonably informs the corporation of the identity
     of the stockholder and that the stockholder intends thereby to demand the
     appraisal of such holder's shares. If such notice did not notify
     stockholders of the effective date of the merger or consolidation, either
     (i) each such constituent corporation shall send a second notice before the
     effective date of the merger or consolidation notifying each of the holders
     of any class or series of stock of such constituent corporation that are
     entitled to appraisal rights of the effective date of the merger or
     consolidation or (ii) the surviving or resulting corporation shall send
     such a second notice to all such holders on or within 10 days after such
     effective date; provided, however, that if such second notice is sent more
     than 20 days following the sending of the first notice, such second notice
     need only be sent to each stockholder who is entitled to appraisal rights
     and who has demanded appraisal of such holder's shares in accordance with
     this subsection. An affidavit of the secretary or assistant secretary or of
     the transfer agent of the corporation that is required to give either
     notice that such notice has been given shall, in the absence of fraud, be
     prima facie evidence of the facts stated therein. For purposes of
     determining the stockholders entitled to receive either notice, each
     constituent corporation may fix, in advance, a record date that shall be
     not more than 10 days prior to the date the notice is given,
                                       D-2


     provided, that if the notice is given on or after the effective date of the
     merger or consolidation, the record date shall be such effective date. If
     no record date is fixed and the notice is given prior to the effective
     date, the record date shall be the close of business on the day next
     preceding the day on which the notice is given.

     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw such stockholder's demand for appraisal and to accept the terms offered
upon the merger or consolidation. Within 120 days after the effective date of
the merger or consolidation, any stockholder who has complied with the
requirements of subsections (a) and (d) hereof, upon written request, shall be
entitled to receive from the corporation surviving the merger or resulting from
the consolidation a statement setting forth the aggregate number of shares not
voted in favor of the merger or consolidation and with respect to which demands
for appraisal have been received and the aggregate number of holders of such
shares. Such written statement shall be mailed to the stockholder within 10 days
after such stockholder's written request for such a statement is received by the
surviving or resulting corporation or within 10 days after expiration of the
period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.

     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by 1 or more publications at
least 1 week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.

     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted
such stockholder's certificates of stock to the Register in Chancery, if such is
required, may

                                       D-3


participate fully in all proceedings until it is finally determined that such
stockholder is not entitled to appraisal rights under this section.

     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded appraisal rights as provided in subsection (d) of
this section shall be entitled to vote such stock for any purpose or to receive
payment of dividends or other distributions on the stock (except dividends or
other distributions payable to stockholders of record at a date which is prior
to the effective date of the merger or consolidation); provided, however, that
if no petition for an appraisal shall be filed within the time provided in
subsection (e) of this section, or if such stockholder shall deliver to the
surviving or resulting corporation a written withdrawal of such stockholder's
demand for an appraisal and an acceptance of the merger or consolidation, either
within 60 days after the effective date of the merger or consolidation as
provided in subsection (e) of this section or thereafter with the written
approval of the corporation, then the right of such stockholder to an appraisal
shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court
of Chancery shall be dismissed as to any stockholder without the approval of the
Court, and such approval may be conditioned upon such terms as the Court deems
just.

     (l) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.

                            DEVON ENERGY CORPORATION

                     2003 OMNIBUS LONG-TERM INCENTIVE PLAN

                                   ARTICLE I

                                    PURPOSE

     SECTION 1.1  Purpose.  This 2003 Omnibus Long-Term Incentive Plan (the
"Plan") is established by Devon Energy Corporation (the "Company") to create
incentives which are designed to motivate Participants to put forth maximum
effort toward the success and growth of the Company and to enable the Company to
attract and retain experienced individuals who by their position, ability and
diligence are able to make important contributions to the Company's success.
Toward these objectives, the Plan provides for the grant of Options, SARs,
Restricted Stock Awards, Performance Units and Performance Bonuses to Eligible
Employees and the grant of Nonqualified Stock Options and Restricted Stock
Awards to Eligible Directors, subject to the conditions set forth in the Plan.
The Plan is designed to provide flexibility to meet the needs of the Company
over three to four years in a changing and competitive environment while
minimizing dilution to the Company's stockholders. The Company does not intend
to use all incentive vehicles (Options, SARs, Restricted Stock Awards,
Performance Units and Performance Bonuses) at all times for each participant but
will selectively grant awards to achieve long-term goals. Awards will be granted
in such a way to align the interests of the participants with those of the
Company's stockholders. Maximum individual awards as designated by this Plan
will only be awarded if individual and Company results are such that exceptional
stockholder value is achieved.

     SECTION 1.2  Establishment.  The Plan is effective as of           , 2003
and for a period of eight years thereafter. The Plan shall continue in effect
until all matters relating to the payment of Awards and administration of the
Plan have been settled.

     The Plan shall be approved by the holders of at least a majority of the
voting power of outstanding shares of Common Stock and the Company's Special
Voting Stock, par value $.10 per share, voting as a single class, present, or
represented, and entitled to vote at a meeting called for such purpose, which
approval must occur within the period ending twelve months after the date the
Plan is adopted by the Board. Pending such approval by the Company's
stockholders, Awards under the Plan may be granted, but no such Awards may be
exercised prior to receipt of such stockholder approval. In the event such
stockholder approval is not obtained within such twelve-month period, all such
Awards shall be void.

     SECTION 1.3  Shares Subject to the Plan.  Subject to the limitations set
forth in the Plan, Awards may be made under this Plan for a total of 12,500,000
shares of Common Stock. A maximum of 2,500,000 shares of the 12,500,000 shares
of Common Stock subject to the Plan may be granted as Restricted Stock Awards
(the "Restricted Stock Award Limit").

                                   ARTICLE II

                                  DEFINITIONS

     SECTION 2.1  "Account" means the record keeping account established by the
Company to which will be credited an Award of Performance Units to a
Participant.

     SECTION 2.2  "Affiliated Entity" means any partnership or limited liability
company in which a majority of the partnership or other similar interest thereof
is owned or controlled, directly or indirectly, by the Company or one or more of
its Subsidiaries or Affiliated Entities or a combination thereof. For purposes
hereof, the Company, a Subsidiary or an Affiliated Entity shall be deemed to
have a majority ownership interest in a partnership or limited liability company
if the Company, such Subsidiary or Affiliated Entity shall be allocated a
majority of partnership or limited liability company gains or losses or shall be
or control a managing director or a general partner of such partnership or
limited liability company.

                                       E-5


     SECTION 2.3  "Award" means, individually or collectively, any Option, SAR,
Restricted Stock Award, Performance Unit or Performance Bonus granted under the
Plan to an Eligible Employee by the Committee or any Nonqualified Stock Option
or Restricted Stock Award granted under the Plan to an Eligible Director by the
Board pursuant to such terms, conditions, restrictions, and/or limitations, if
any, as the Committee may establish by the Award Agreement or otherwise.

     SECTION 2.4  "Award Agreement" means any written instrument that
establishes the terms, conditions, restrictions, and/or limitations applicable
to an Award in addition to those established by this Plan and by the Committee's
exercise of its administrative powers.

     SECTION 2.5  "Board" means the Board of Directors of the Company.

     SECTION 2.6  "Change of Control Event" shall be deemed to have occurred
each time any one of the events described in paragraphs (i), (ii), (iii), or
(iv) below occurs; provided that if a Change of Control Event occurs by reason
of an acquisition by any Person that comes within the provisions of paragraph
(i) below, no additional Change of Control Event shall be deemed to occur under
such paragraph (i) by reason of subsequent changes in holdings by such Person
(except if the holdings by such Person are reduced below 30% and thereafter
increase to 30% or above). For the purpose of this Section 2.7, the term
"Company" shall include Devon Energy Corporation and any successor thereto.

     (i) The acquisition by any individual, entity or group (within the meaning
of Section 13(d)(3) or 14(d)(2) of the Exchange Act) (a "Person") if,
immediately after such acquisition, such Person has beneficial ownership (within
the meaning of Rule 13d-3 promulgated under the Exchange Act) of 30% or more of
either (I) the then outstanding shares of common stock of the Company (the
"Outstanding Company Common Stock") or (II) the combined voting power of the
then outstanding voting securities of the Company entitled to vote generally in
the election of directors (the "Outstanding Company Voting Securities");
provided, however, that the following acquisitions shall not constitute a Change
of Control Event: (A) any acquisition by an underwriter temporarily holding
securities pursuant to an offering of such securities; (B) any acquisition by
the Company; (C) any acquisition by any employee benefit plan (or related trust)
sponsored or maintained by the Company or any corporation controlled by the
Company; or (D) any acquisition by any corporation pursuant to a transaction
which complies with clauses (A), (B), and (C) of paragraph (iii) below.

     (ii) Individuals who, as of the effective date of this Plan, constitute the
Board (the "Incumbent Board") cease for any reason to constitute at least a
majority of the Board; provided, however, that any individual becoming a
director subsequent to the effective date whose election, appointment or
nomination for election by the Company's stockholders was approved by a vote of
at least a majority of the directors then comprising the Incumbent Board shall
be considered as though such individual were a member of the Incumbent Board,
but excluding, for purposes of this definition, any such individual whose
initial assumption of office occurs as a result of an actual or publicly
threatened election contest (as such terms are used in Rule 14a-11 promulgated
under the Exchange Act) with respect to the election or removal of directors or
other actual or publicly threatened solicitation of proxies or consents by or on
behalf of a Person other than the Board.

     (iii) A reorganization, share exchange, merger or consolidation (a
"Business Combination"), in each case, unless, following such Business
Combination, (A) all or substantially all of the individuals and entities who
were the beneficial owners, respectively, of the Outstanding Company Common
Stock and Outstanding Company Voting Securities immediately prior to such
Business Combination beneficially own, directly or indirectly, more than 50% of,
respectively, the then outstanding shares of common stock and the combined
voting power of the then outstanding voting securities entitled to vote
generally in the election of directors, as the case may be, of the ultimate
parent entity resulting from such Business Combination (including, without
limitation, an entity which, as a result of such transaction, has ownership of
the Company or all or substantially all of the assets of the Company either
directly or through one or more subsidiaries) in substantially the same relative
proportions as their ownership, immediately prior to such Business Combination,
of the Outstanding Company Common Stock and Outstanding Company Voting
Securities, as the case may be, (B) no Person (excluding any employee benefit
plan (or related
                                       E-6


trust) of the Company or such corporation resulting from such Business
Combination) beneficially owns, directly or indirectly, 30% or more of,
respectively, the then outstanding common stock of the ultimate parent entity
resulting from such Business Combination or the combined voting power of the
then outstanding voting securities of such entity except to the extent that such
ownership existed prior to the Business Combination, and (C) at least a majority
of the members of the board of directors of the corporation resulting from such
Business Combination were members of the Incumbent Board at the time of the

     SECTION 5.1  Grant of Options.  The Committee may, from time to time,
subject to the provisions of the Plan and such other terms and conditions as it
may determine, grant Options to Eligible Employees. These Options may be
Incentive Stock Options or Nonqualified Stock Options, or a combination of both.
Each grant of an Option shall be evidenced by an Award Agreement executed by the
Company and the Eligible Employee, and shall contain such terms and conditions
and be in such form as the Committee may from time to time approve, subject to
the requirements of Section 5.2. The Board may, subject to the provisions of the

          (a) Exercise Price.  As limited by Section 5.2(e) below, each Option
     shall state the exercise price which shall be set by the Committee at the
     Date of Grant; provided, however, no Option shall be granted at an exercise
     price which is less than the Fair Market Value of the Common Stock on the

          (b) Form of Payment.  The exercise price of an Option may be paid (i)
     in cash or by check, bank draft or money order payable to the order of the
     Company; (ii) by delivering shares of Common Stock having a Fair Market
     Value on the date of payment equal to the amount of the exercise price, but
     only to the extent such exercise of an Option would not result in a
     compensation expense to the Company for financial accounting purposes with
     respect to the shares used to pay the exercise price unless otherwise
     determined by the Committee; or (iii) a combination of the foregoing. In
     addition to the foregoing, the Committee may permit an Option granted under
     the Plan to be exercised by a broker-dealer acting on behalf of a
     Participant through procedures approved by the Committee.

          (c) Exercise of Options.  Options granted under the Plan shall be
     exercisable, in whole or in such installments and at such times, and shall
     expire at such time, as shall be provided by the Committee in the Award
     Agreement. Exercise of an Option shall be by notice to the Secretary of
     such exercise stating the election to exercise in the form and manner
     determined by the Committee. Every share of Common Stock acquired through
     the exercise of an Option shall be deemed to be fully paid at the time of
     exercise and payment of the exercise price.

          (d) Other Terms and Conditions.  Among other conditions that may be
     imposed by the Committee, if deemed appropriate, are those relating to (i)
     the period or periods and the conditions of exercisability of any Option;
     (ii) the minimum periods during which Participants must be employed by the
     Company, its Subsidiaries, or an Affiliated Entity, or must hold Options
     before they may be exercised; (iii) the minimum periods during which shares
     acquired upon exercise must be held before sale or transfer shall be
     permitted; (iv) conditions under which such Options or shares may be
     subject to forfeiture; (v) the frequency of exercise or the minimum or
     maximum number of shares that may be acquired at any one time; (vi) the
     achievement by the Company of specified performance criteria; and (vii)
     non-compete and protection of business matters.

          (e) Special Restrictions Relating to Incentive Stock Options.  Options
     issued in the form of Incentive Stock Options shall only be granted to
     Eligible Employees of the Company or a Subsidiary, and not to Eligible
     Employees of an Affiliated Entity unless such entity shall be considered as
     a "disregarded entity" under the Code and shall not be distinguished for
     federal tax purposes from the Company or the applicable Subsidiary.
     Furthermore, Incentive Stock Options shall, in addition to
                                       E-11


     being subject to all applicable terms, conditions, restrictions and/or
     limitations established by the Committee, comply with the requirements of
     Section 422 of the Code, including, without limitation, (i) the requirement
     that the aggregate Fair Market Value (determined on the Date of Grant) of
     the Common Stock with respect to which Incentive Stock Options are
     exercisable for the first time by a Participant during any calendar year
     (under this Plan or any other plan of the Company or any Subsidiary) not
     exceed $100,000; and (ii) the requirement that the exercise price of an
     Incentive Stock Option granted to an Eligible Employee who owns more than
     10% of the combined voting power of the Company or its Subsidiaries on the
     date of grant shall not be less than 110% of the Fair Market Value of a
     share of Common Stock on the date the Incentive Stock Option is granted and
     the term of such option shall not exceed five years.

          (f) Application of Funds.  The proceeds received by the Company from
     the sale of Common Stock pursuant to Options will be used for general
     corporate purposes.

          (g) Stockholder Rights.  No Participant shall have a right as a
     stockholder with respect to any share of Common Stock subject to an Option
     prior to purchase of such shares of Common Stock by exercise of the Option.

                                   ARTICLE VI

terms and conditions as the Committee may determine, grant a SAR to any
Participant. SARs may be granted in tandem with an Option, in which event, the
Participant has the right to elect to exercise either the SAR or the Option.
Upon the Participant's election to exercise one of these Awards, the other
tandem Award is automatically terminated. SARs may also be granted as an
independent Award separate from an Option. Each grant of a SAR shall be
evidenced by an Award Agreement executed by the Company and the Participant and
shall contain such terms and conditions and be in such form as the Committee may
from time to time approve, subject to the requirements of the Plan.

     SECTION 6.2  Exercise.  The amount payable with respect to each SAR shall
be equal in value to the applicable percentage of the excess, if any, of the
Fair Market Value of a share of Common Stock on the exercise date over the
exercise price of the SAR. The exercise price of the SAR shall be determined by
the Committee and shall not be less than the Fair Market Value of a share of
Common Stock on the date the SAR is granted. The applicable percentage and
exercise price shall be established by the Committee at the time the SAR is
granted.

     SECTION 6.3  Restrictions.  In the event a SAR is granted in tandem with an
Incentive Stock Option, the Committee shall subject the SAR to restrictions
necessary to ensure satisfaction of the requirements under Section 422 of the
Code. In the case of a SAR granted in tandem with an Incentive Stock Option to
an Eligible Employee who owns more than 10% of the combined voting power of the
Company or its Subsidiaries on the date of such grant, the amount payable with
respect to each SAR shall be equal in value to the applicable percentage of the
excess, if any, of the Fair Market Value of a share of Common Stock on the
exercise date over the exercise price of the SAR, which exercise price shall not
be less than 110% of the Fair Market Value of a share of Common Stock on the
date the SAR is granted.

deems appropriate, including, without limitation, a book-entry registration or
issuance of a stock certificate or certificates, and by an Award Agreement
setting forth the terms of such Restricted Stock Award.

     SECTION 7.2  Conditions of Restricted Stock Awards.  The grant of a
Restricted Stock Award shall be subject to the following:

          (a) Restriction Period.  Each Restricted Stock Award shall require the
     holder to remain in the employment of the Company, a Subsidiary, or an
     Affiliated Entity for a prescribed period (a "Restriction Period"). Subject
     to Sections 4.1(i) and (j), the Committee shall determine the Restriction
     Period or Periods that shall apply to the shares of Common Stock covered by
     each Restricted Stock Award or portion thereof. In addition to any time
     vesting conditions determined by the Committee, Restricted Stock Awards may
     be subject to the achievement by the Company of specified performance
     criteria based upon the Company's achievement of operational, financial or
     stock performance criteria more specifically listed in Exhibit A attached,
     as established by the Committee. At the end of the Restriction Period,
     assuming the fulfillment of any other specified vesting conditions, the
     restrictions imposed by the Committee shall lapse with respect to the
     shares of Common Stock covered by the Restricted Stock Award or portion
     thereof.

          (b) Restrictions.  The holder of a Restricted Stock Award may not
     sell, transfer, pledge, exchange, hypothecate, or otherwise dispose of the
     shares of Common Stock represented by the Restricted Stock Award during the
     applicable Restriction Period. The Committee shall impose such other
     restrictions and conditions on any shares of Common Stock covered by a
     Restricted Stock Award as it may deem advisable including, without
     limitation, restrictions under applicable Federal or state securities laws,
     and may legend the certificates representing Restricted Stock to give
     appropriate notice of such restrictions.

          (c) Rights as Stockholders.  During any Restriction Period, the
     Committee may, in its discretion, grant to the holder of a Restricted Stock
     Award all or any of the rights of a stockholder with respect to the shares,
     including, but not by way of limitation, the right to vote such shares and
     to receive dividends. If any dividends or other distributions are paid in
     shares of Common Stock, all such shares shall be subject to the same
     restrictions on transferability as the shares of Restricted Stock with
     respect to which they were paid.

                                  ARTICLE VIII

     performance targets for each Award for a period of no less than a year
     based upon some or all of the operational, financial or performance
     criteria listed in Exhibit A attached. The Committee shall also establish
     such other terms and conditions as it deems appropriate to such Award. The
     Award may be paid out in cash or Common Stock as determined in the sole
     discretion of the Committee.

     SECTION 9.1  Grant of Performance Bonus.  The Committee may from time to
time, subject to the provisions of the Plan and such other terms and conditions
as the Committee may determine, grant a Performance Bonus to certain Eligible
Employees selected for participation. The Committee will determine the amount
that may be earned as a Performance Bonus in any period of one year or more upon

Performance Bonus shall be made within 60 days of the Committee's certification
that the performance target has been achieved unless the Participant has elected
to defer payment pursuant to a non-qualified deferred compensation plan adopted
by the Company. Payment of a Performance Bonus may be made in either cash or
Common Stock as determined in the sole discretion of the Committee.

                                   ARTICLE X

                               STOCK ADJUSTMENTS

     SECTION 10.1  Stock Adjustments.  In the event that the shares of Common
Stock, as constituted on the effective date of the Plan, shall be changed into
or exchanged for a different number or kind of shares of stock or other
securities of the Company or of another corporation (whether by reason of
merger, consolidation, recapitalization, reclassification, stock split,
combination of shares or otherwise), or if the number of such shares of Common
Stock shall be increased through the payment of a stock dividend, or if rights
or warrants to purchase securities of the Company shall be issued to holders of
all outstanding Common Stock, then there shall be substituted for or added to
each share available under and subject to the Plan, and each share theretofore
appropriated under the Plan, the number and kind of shares of stock or other
securities into which each outstanding share of Common Stock shall be so changed
or for which each such share shall be exchanged or to which each such share
shall be entitled, as the case may be, on a fair and equivalent basis in
accordance with the applicable provisions of Section 424 of the Code; provided,
however, with respect to Options, in no such event will such adjustment result
in a modification of any Option as defined in Section 424(h) of the Code. In the
event there shall be any other change in the number or kind of the outstanding
shares of Common Stock, or any stock or other securities into which the Common
Stock shall have been changed or for which it shall have been exchanged, then if
the Committee shall, in its sole discretion, determine that such change
equitably requires an adjustment in the shares available under and subject to
the Plan, or in any Award, theretofore granted, such adjustments shall be made
in accordance with such determination, except that no adjustment of the number
of shares of Common Stock available under the Plan or to which any Award relates
that would otherwise be required shall be made unless and until such adjustment
either by itself or with other adjustments not previously made would require an
increase or decrease of at least 1% in the number of shares of Common Stock
available under the Plan or to which any Award relates immediately prior to the
making of such adjustment (the "Minimum Adjustment"). Any adjustment
representing a change of less than such minimum amount shall be carried forward
and made as soon as such adjustment together with other adjustments required by
this Article X and not previously made would result in a Minimum Adjustment.
Notwithstanding the foregoing, any adjustment required by this Article X which
otherwise would not result in a Minimum Adjustment shall be made with respect to
shares of Common Stock relating to any Award immediately prior to exercise,
payment or settlement of such Award.

                                       E-14


     No fractional shares of Common Stock or units of other securities shall be
issued pursuant to any such adjustment, and any fractions resulting from any
such adjustment shall be eliminated in each case by rounding downward to the
nearest whole share.

                                   ARTICLE XI

                                    GENERAL

     SECTION 11.1  Amendment or Termination of Plan.  The Board may alter,
suspend or terminate the Plan at any time. In addition, the Board may, from time
to time, amend the Plan in any manner, but may not without stockholder approval
adopt any amendment which would (i) increase the aggregate number of shares of
Common Stock available under the Plan (except by operation of Article X), (ii)
materially modify the requirements as to eligibility for participation in the
Plan, or (iii) materially increase the benefits to Participants provided by the
Plan.

     SECTION 11.2  Termination of Employment; Termination of Service.  If an
Eligible Employee's employment with the Company, a Subsidiary, or an Affiliated
Entity terminates for a reason other than death, disability, retirement, or any
approved reason, all unexercised, unearned, and/or unpaid Awards, including, but
not by way of limitation, Awards earned, but not yet paid, all unpaid dividends
and dividend equivalents, and all interest, if any, accrued on the foregoing
shall be cancelled or forfeited, as the case may be, unless the Eligible
Employee's Award Agreement provides otherwise. The Compensation Committee shall
(i) determine what events constitute disability, retirement, or termination for
an approved reason for purposes of the Plan, and (ii) determine the treatment of
a Participant under the Plan in the event of his death, disability, retirement,
or termination for an approved reason. The Committee shall also determine the
method, if any, for accelerating the vesting or exercisability of any Awards, or
providing for the exercise of any unexercised Awards in the event of an Eligible
Employee's death, disability, retirement, or termination for an approved reason.

     In the event an Eligible Director terminates service as a director of the
Company, the unvested portion of any Award shall be forfeited unless otherwise
accelerated pursuant to the terms of the Eligible Director's Award Agreement or
by the Board. The Eligible Director shall have a period of three years following
the date he ceases to be a director to exercise any Nonqualified Stock Options
which are otherwise exercisable on his date of termination of service.

     SECTION 11.3  Limited Transferability -- Options.  The Committee may, in
its discretion, authorize all or a portion of the Nonqualified Stock Options
granted under this Plan to be on terms which permit transfer by the Participant
to (i) the ex-spouse of the Participant pursuant to the terms of a domestic
relations order, (ii) the spouse, children or grandchildren of the Participant
("Immediate Family Members"), (iii) a trust or trusts for the exclusive benefit
of such Immediate Family Members, or (iv) a partnership or limited liability
company in which such Immediate Family Members are the only partners or members.
In addition there may be no consideration for any such transfer, the Award
Agreement pursuant to which such Nonqualified Stock Options are granted must be
approved by the Committee, and must expressly provide for transferability in a
manner consistent with this paragraph. Subsequent transfers of transferred
Nonqualified Stock Options shall be prohibited except as set forth below in this
Section 11.3. Following transfer, any such Nonqualified Stock Options shall
continue to be subject to the same terms and conditions as were applicable
immediately prior to transfer, provided that for purposes of Section 11.2 hereof
the term "Participant" shall be deemed to refer to the transferee. The events of
termination of employment of Section 11.2 hereof shall continue to be applied
with respect to the original Participant, following which the Nonqualified Stock
Options shall be exercisable by the transferee only to the extent, and for the
periods specified in Section 11.2 hereof. No transfer pursuant to this Section
11.3 shall be effective to bind the Company unless the Company shall have been
furnished with written notice of such transfer together with such other
documents regarding the transfer as the Committee shall request. With the
exception of a transfer in compliance with the foregoing provisions of this
Section 11.3, Awards shall be transferable only by will or the laws of descent
and distribution; however, no such transfer shall be effective to bind the
Company unless the Committee has been furnished with written notice of such
                                       E-15


transfer and an authenticated copy of the will and/or such other evidence as the
Committee may deem necessary to establish the validity of the transfer and the
acceptance by the transferee of the terms and conditions of such Award.

     SECTION 11.4  Withholding Taxes.  Unless otherwise paid by the Participant,
the Company shall be entitled to deduct from any payment under the Plan,
regardless of the form of such payment, the amount of all applicable income and
employment taxes required by law to be withheld with respect to such payment or
may require the Participant to pay to it such tax prior to and as a condition of
the making of such payment. In accordance with any applicable administrative
guidelines it establishes, the Committee may allow a Participant to pay the
amount of taxes required by law to be withheld from an Award by (i) directing
the Company to withhold from any payment of the Award a number of shares of
Common Stock having a Fair Market Value on the date of payment equal to the
amount of the required withholding taxes or (ii) delivering to the Company
previously owned shares of Common Stock having a Fair Market Value on the date
of payment equal to the amount of the required withholding taxes. However, any
payment made by the Participant pursuant to either of the foregoing clauses (i)
or (ii) shall not be permitted if it would result in an accounting charge with
respect to such shares used to pay such taxes unless otherwise approved by the
Committee.

     SECTION 11.5  Dividends and Dividend Equivalents -- Awards.  The Committee
may choose, at the time of the grant of any Award or any time thereafter up to
the time of payment of such Award, to include as part of such Award an
entitlement to receive dividends or dividend equivalents subject to such terms,
conditions, restrictions, and/or limitations, if any, as the Committee may
establish. Dividends and dividend equivalents granted hereunder shall be paid in
such form and manner (i.e., lump sum or installments), and at such time as the
Committee shall determine. All dividends or dividend equivalents which are not
paid currently may, at the Committee's discretion, accrue interest.

     SECTION 11.6  Change of Control.  Notwithstanding any other provision in
this Plan to the contrary, Awards granted under the Plan to any Eligible
Employee or Eligible Director may, in the discretion of the Committee, provide
in the Award Agreement that such Awards shall be immediately vested, fully
earned and exercisable upon the occurrence of a Change of Control Event.

     SECTION 11.7  Amendments to Awards.  Subject to the limitations of Article
IV, such as the prohibition on repricing of Options, the Committee may at any
time unilaterally amend the terms of any Award Agreement, whether or not
presently exercisable or vested, to the extent it deems appropriate. However,
amendments which are adverse to the Participant shall require the Participant's
consent.

     SECTION 11.8  Regulatory Approval and Listings.  The Company shall use its
best efforts to file with the Securities and Exchange Commission as soon as
practicable following approval by the stockholders of the Company of the Plan as
provided in Section 1.2 of the Plan, and keep continuously effectively, a
Registration Statement on Form S-8 with respect to shares of Common Stock
subject to Awards hereunder. Notwithstanding anything contained in this Plan to
the contrary, the Company shall have no obligation to issue shares of Common
Stock under this Plan prior to:

          (a) the obtaining of any approval from, or satisfaction of any waiting
     period or other condition imposed by, any governmental agency which the
     Committee shall, in its sole discretion, determine to be necessary or
     advisable;

          (b) the admission of such shares to listing on the stock exchange on
     which the Common Stock may be listed; and

          (c) the completion of any registration or other qualification of such
     shares under any state or Federal law or ruling of any governmental body
     which the Committee shall, in its sole discretion, determine to be
     necessary or advisable.

     SECTION 11.9  Right to Continued Employment.  Participation in the Plan
shall not give any Eligible Employee any right to remain in the employ of the
Company, any Subsidiary, or any Affiliated Entity. The Company or, in the case
of employment with a Subsidiary or an Affiliated Entity, the

                                       E-16


Subsidiary or Affiliated Entity reserves the right to terminate any Eligible
Employee at any time. Further, the adoption of this Plan shall not be deemed to
give any Eligible Employee or any other individual any right to be selected as a
Participant or to be granted an Award.

     SECTION 11.10  Beneficiary Designation.  In the event of the death of a
Participant, the portion of the Participant's Award with respect to which
vesting dates have occurred shall be paid to the then surviving beneficiary
designated by the Participant, and if there is no beneficiary then surviving,
then such benefits will automatically be paid to the estate of the Participant.

     SECTION 11.11  Reliance on Reports.  Each member of the Committee and each
member of the Board shall be fully justified in relying or acting in good faith
upon any report made by the independent public accountants of the Company and
its Subsidiaries and upon any other information furnished in connection with the
Plan by any person or persons other than himself or herself. In no event shall
any person who is or shall have been a member of the Committee or of the Board
be liable for any determination made or other action taken or any omission to
act in reliance upon any such report or information or for any action taken,
including the furnishing of information, or failure to act, if in good faith.

     SECTION 11.12  Construction.  Masculine pronouns and other words of
masculine gender shall refer to both men and women. The titles and headings of
the sections in the Plan are for the convenience of reference only, and in the
event of any conflict, the text of the Plan, rather than such titles or
headings, shall control.

     SECTION 11.13  Governing Law.  The Plan shall be governed by and construed
in accordance with the laws of the State of Delaware except as superseded by
applicable Federal law.

     SECTION 11.14  Severability.  If any provision of the Plan or any Award is
or becomes or is deemed to be invalid, illegal, or unenforceable in any
jurisdiction or as to any Participant or Award, or would disqualify the Plan or
any Award under any law deemed applicable by the Committee, such provision shall
be construed or deemed amended to conform to the applicable laws, or if it
cannot be construed or deemed amended without, in the determination of the
Committee, materially altering the intent of the Plan or the Award, such
provision shall be stricken as to such jurisdiction, Participant or Award and
the remainder of the Plan and any such Award shall remain in full force and
effect.

     SECTION 11.15  Other Laws.  The Committee may refuse to issue or transfer
any shares of Common Stock or other consideration under an Award if, acting in
its sole discretion, it determines that the issuance or transfer of such shares
or such other consideration might violate any applicable law or regulation or
entitle the Company to recover the same under Section 16(b) of the Exchange Act,
and any payment tendered to the Company by a Participant, other holder or
beneficiary in connection with the exercise of such Award shall be promptly
refunded to the relevant Participant, holder or beneficiary.

     SECTION 11.16  No Trust or Fund Created.  Neither the Plan nor an Award
shall create or be construed to create a trust or separate fund of any kind or a
fiduciary relationship between the Company and a Participant or any other
person. To the extent that a Participant acquires the right to receive payments
from the Company pursuant to an Award, such right shall be no greater than the
right of any general unsecured creditor of the Company.

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Except to the extent indicated below, there is no charter provision, bylaw,
contract, arrangement or statute under which any director or officer of Devon is
insured or indemnified in any manner against any liability that he or she may
incur in his or her capacity as such.

DEVON ENERGY CORPORATION

     Article VIII of Devon's restated certificate of incorporation, as amended,
contains a provision, permitted by Section 102(b)(7) of the Delaware General
Corporation Law, limiting the personal monetary liability of directors for
breach of fiduciary duty as a director. This provision and Delaware law provide
that the provision does not eliminate or limit liability:

     - for any breach of the director's duty of loyalty to Devon or its
       stockholders;

     - for acts or omissions not in good faith or which involve intentional
       misconduct or a knowing violation of law;

     - for unlawful payments of dividends or unlawful stock repurchases or
       redemptions, as provided in Section 174 of the Delaware General
       Corporation Law; or

     - for any transaction from which the director derived an improper personal
       benefit.

     Section 145 of the Delaware General Corporation Law permits indemnification
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred in connection with actions, suits
or proceedings in which a director, officer, employee or agent is a party by
reason of the fact that he or she is or was such a director, officer, employee
or agent, if he or she acted in good faith and in a manner he or she reasonably
believed to be in or not opposed to the best interests of the corporation and
with respect to any criminal action or proceeding, had no reasonable cause to
believe his or her conduct was unlawful. However, in connection with actions by
or in the right of the corporation, such indemnification is not permitted if
such person has been adjudged liable to the corporation unless the court
determines that, under all of the circumstances, such person is nonetheless
fairly and reasonably entitled to indemnity for such expenses as the court deems
proper. Article X of Devon's restated certificate of incorporation, as amended,
provides for such indemnification.

     Section 145 of the Delaware General Corporation Law also permits a
corporation to purchase and maintain insurance on behalf of its directors and
officers against any liability that may be asserted against, or incurred by,
such persons in their capacities as directors or officers of the corporation
whether or not the corporation would have the power to indemnify such persons
against such liabilities under the provisions of such sections. Devon has
purchased such insurance.

     Section 145 of the Delaware General Corporation Law further provides that
the statutory provision is not exclusive of any other right to which those
seeking indemnification or advancement of expenses may be entitled under any
bylaw, agreement, vote of stockholders or independent directors, or otherwise,
both as to action in such person's official capacity and as to action in another
capacity while holding such office.

     Article VIII of Devon's bylaws contains provisions regarding
indemnification that parallel those described above.

     The amended and restated merger agreement, dated as of May 19, 1999,
between Devon and PennzEnergy Company provides that for seven years after the
effective time of the merger contemplated by that agreement, Devon will
indemnify and hold harmless each person who was a director or officer of Devon
or PennzEnergy prior to the effective time of that merger from their acts or
omissions in those capacities occurring prior to the effective time of that
merger to the fullest extent permitted by applicable law.
                                       II-1


     The merger agreement, dated as of May 25, 2000, as amended, between Devon
and Santa Fe Snyder Corporation provides that for six years after the effective
time of the merger contemplated by that agreement, Devon will indemnify and hold
harmless each person who was a director or officer of Santa Fe Snyder prior to
the effective time of that merger from their acts or omissions in those
capacities occurring prior to the effective time of that merger to the fullest
extent permitted by applicable law.

     The amended and restated agreement and plan of merger, dated as of August
13, 2001, by and among Devon, Devon NewCo Corporation, Devon Holdco Corporation,
Devon Merger Corporation, Mitchell Merger Corporation and Mitchell Energy &
Development Corp. provides that for six years after the effective time of the
merger contemplated by that agreement, Devon will cause the surviving
corporation of the merger to indemnify and hold harmless to the fullest extent
permitted under applicable law each person who was a director or officer of
Mitchell prior to the effective time of that merger.

     The Pre-Acquisition Agreement, dated as of August 31, 2001, by and between
Devon Energy Corporation and Anderson Exploration Ltd. provides that after the
effective time of the acquisition of Anderson, Devon will cause Anderson to
indemnify and hold harmless to the fullest extent permitted under applicable law
each person who was a director or officer of Anderson prior to the effective
time of the Anderson acquisition.

     The agreement and plan of merger, dated as of February 23, 2003, by and
among Devon, Devon NewCo Corporation and Ocean Energy, Inc. provides that after
the effective time of the merger contemplated by that agreement, Devon will
cause the surviving corporation of the merger to indemnify and hold harmless to
the fullest extent permitted under applicable law each person who was a director
or officer of Ocean prior to the effective time of that merger.

ITEM 21. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES

     (a) Exhibits

     item.

     (b) Financial Statement Schedule

          Not applicable.

ITEM 22.  UNDERTAKINGS

     The undersigned registrant hereby undertakes:

          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:

             (i) to include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;

             (ii) to reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in the registration statement. Notwithstanding the foregoing, any
        increase or decrease in volume of securities offered (if the total
        dollar value of securities offered would not exceed that which was
        registered) and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of prospectus filed
        with the Commission pursuant to Rule 424(b) if, in the aggregate, the
        changes in volume and price represent no more than a 20% change in the
        maximum aggregate offering price set forth in the "Calculation of
        Registration Fee" table in the effective registration statement; and

             (iii) to include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement;

             provided, however, that paragraphs (1)(i) and (1)(ii) do not apply
        if the information required to be included in a post-effective amendment
        by those paragraphs is contained in

                                       II-2


        periodic reports filed by Devon pursuant to Section 13 or Section 15(d)
        of the Securities Exchange Act of 1934 that are incorporated by
        reference in the registration statement;

          (2) That, for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.

          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.

          (4) That, for the purpose of determining any liability under the
     Securities Act of 1933, each filing of Devon's annual report pursuant to
     Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where
     applicable, each filing of an employee benefit plan's annual report
     pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is
     incorporated by reference in the registration statement shall be deemed to
     be a new registration statement relating to the securities offered therein,
     and the offering of such securities at that time shall be deemed to be the
     initial bona fide offering thereof.

          (5) That, prior to any public reoffering of the securities registered
     hereunder through use of a prospectus which is a part of this registration
     statement, by any person or party who is deemed to be an underwriter within
     the meaning of Rule 145(c), the issuer undertakes that such reoffering
     prospectus will contain the information called for by the applicable
     registration form with respect to reofferings by persons who may be deemed
     underwriters, in addition to the information called for by the other items
     of the applicable form.

          (6) That every prospectus: (i) that is filed pursuant to paragraph (5)
     immediately preceding, or (ii) that purports to meet the requirements of
     Section 10(a)(3) of the Securities Act of 1933 and is used in connection
     with an offering of securities subject to Rule 415, will be filed as a part
     of an amendment to the registration statement and will not be used until
     such amendment is effective, and that, for purposes of determining any
     liability under the Securities Act of 1933, each such post-effective
     amendment shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

          (7) To respond to requests for information that is incorporated by
     reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this
     form, within one business day of receipt of such request, and to send the
     incorporated documents by first class mail or other equally prompt means.
     This includes information contained in documents filed subsequent to the
     effective date of the registration statement through the date of responding
     to the request.

          (8) To supply by means of a post-effective amendment all information
     concerning a transaction, and the company being acquired involved therein,
     that was not the subject of and included in the registration statement when
     it became effective.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described under Item 20, or otherwise,
each registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act of 1933 and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by a registrant of expenses incurred or paid by a director, officer or
controlling person of such registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933 and will be governed by the final adjudication of such
issue.

                                       II-3


                                   SIGNATURES

     Pursuant to the requirements of the Securities Act of 1933, the registrant
has duly caused this registration statement to be signed on its behalf by the
undersigned, thereunto duly authorized, in the city of Oklahoma City, state of
Oklahoma, on March 7, 2003.
