                        SPECIAL MEETING OF STOCKHOLDERS
                 MERGER PROPOSED -- YOUR VOTE IS VERY IMPORTANT

Dear Predictive Systems, Inc. Stockholder:

   The board of directors of Predictive Systems, Inc. has unanimously approved
a merger pursuant to which Predictive will be acquired by International
Network Services, Inc., or INS.

   If the merger is completed, holders of Predictive's common stock will
receive approximately $0.46 in cash, without interest, for each share of
Predictive's common stock they own. The exact amount of cash holders will
receive per share of Predictive common stock cannot be determined until the
closing of the merger, but will initially be equal to $19,186,700, divided by
the number of shares of Predictive common stock and the number of shares of
Predictive common stock subject to "in-the-money" options outstanding at the
closing. The $19,186,700 aggregate consideration will be increased if and to
the extent our net assets at closing exceed our estimates of our net assets at
closing set forth in the merger agreement by more than $1,250,000, and will be
decreased if and to the extent our net assets at closing are less than our
estimates of our net assets at closing set forth in the merger agreement by
more than $1,250,000. The approximately $0.46 initial per share consideration
also assumes the successful completion of our sale of certain assets to
Science Applications International Corporation, or SAIC, prior to the closing
of the merger. If the asset sale to SAIC does not occur, we expect the $0.46
initial per share consideration to be reduced to approximately $0.42 per
share. The potential adjustment regarding our closing net assets will apply
regardless of whether or not the SAIC transaction is consummated.

   Stockholders of Predictive will be asked, at a special meeting of
Predictive's stockholders, to adopt and approve the merger agreement and
approve the merger. In connection with its evaluation of our strategic
alternatives, including the merger, the board engaged Updata Capital, Inc. for
the purpose of evaluating the fairness, from a financial point of view, of the
merger consideration to the holders of the outstanding shares of our common
stock. Updata Capital delivered its written opinion to our board of directors
to the effect that, as of April 8, 2003, and based upon and subject to the
factors and assumptions set forth in its written opinion, the merger
consideration to be received by holders of our common stock pursuant to the
merger agreement, whether or not the SAIC transaction is consummated prior to
the closing of the merger, is fair from a financial point of view to those
holders. In addition, the board of directors of Predictive has unanimously
determined that the merger is advisable to, and in the best interests of,
Predictive and our stockholders, approved the merger agreement, the merger and
the other transactions contemplated by the merger agreement, and declared that
it is in the best interests of Predictive's stockholders that you adopt and
approve the merger agreement and approve the merger on the terms and
conditions set forth in the merger agreement. The board of directors of
Predictive unanimously recommends that Predictive's stockholders vote FOR
adoption and approval of the merger agreement and approval of the merger.

   The date, time and place of the special meeting to consider and vote upon a
proposal to adopt the merger agreement is as follows:

     ___________, 2003
     10:00 a.m., local time
     19 West 44th Street, 9th Floor
     New York, New York 10036

   The proxy statement attached to this letter provides you with information
about the special meeting of Predictive's stockholders and the proposed
merger. We encourage you to read the entire proxy statement carefully.

   Your vote is very important. Whether or not you plan to attend the special
meeting, if you are a holder of Predictive common stock please take the time
to vote by completing, signing, dating and mailing the enclosed proxy card to
us.

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

                   NOTICE OF SPECIAL MEETING OF STOCKHOLDERS
                        TO BE HELD ON ____________, 2003


To the Stockholders of Predictive Systems, Inc.:

   A special meeting of stockholders of Predictive Systems, Inc., a Delaware
corporation, will be held on ____________, 2003 at 10:00 a.m., local time, at
our headquarters located at 19 West 44th Street, 9th Floor, New York, New
York, 10036, for the following purposes:

   1. To consider and vote upon a proposal to adopt and approve the Agreement
and Plan of Merger, dated as of April 8, 2003, among International Network
Services, Inc., a Delaware corporation, Mid-West Acquisition Corporation, a
Delaware corporation and a wholly-owned subsidiary of INS, and Predictive,
pursuant to which Predictive will become a wholly-owned subsidiary of INS, and
to approve the merger of Predictive as contemplated in the merger agreement;
and

   2. To transact such other business as may properly come before the special
meeting or any adjournment or postponement thereof.

   The board of directors of Predictive has fixed the close of business on
____________, 2003 as the record date for the determination of stockholders
entitled to notice of, and to vote at, the special meeting and any adjournment
or postponement thereof. Only holders of record of shares of Predictive's
common stock at the close of business on the record date are entitled to
notice of, and to vote at, the special meeting or any adjournment or
postponement thereof. At the close of business on the record date, Predictive
had outstanding and entitled to vote ____________ shares of common stock.
Holders of Predictive's common stock are entitled to appraisal rights under
the Delaware General Corporation Law in connection with the merger if they
meet certain conditions. See "The Merger -- Appraisal Rights."

   Your vote is important. The affirmative vote of the holders of a majority of
the outstanding shares of Predictive's common stock is required to adopt and
approve the merger agreement and approve the merger. Even if you plan to
attend the special meeting in person, we request that you complete, sign, date
and return the enclosed proxy and thus ensure that your shares will be
represented at the special meeting if you are unable to attend. If you sign,
date and mail your proxy card without indicating how you wish to vote, your
proxy will be counted as a vote in favor of adoption and approval of the
merger agreement and approval of the merger. If you fail to return your
Predictive proxy card, the effect will be that your shares will not be counted
for purposes of determining whether a quorum is present at the Predictive
special meeting but will effectively be counted as a vote against adoption and
approval of the merger agreement and against approval of the merger. If you do
attend the special meeting and wish to vote in person, you may withdraw your
proxy and vote in person.

                            By order of the Board of Directors

                     QUESTIONS AND ANSWERS ABOUT THE MERGER


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

A:   If the merger is completed, we will become a wholly-owned subsidiary of
     International Network Services, Inc., or INS.

Q:   What will Predictive's stockholders receive in the merger?

A:   As a result of the merger, our stockholders will receive approximately
     $0.46 in cash, without interest, for each share of our common stock they
     own. For example, if you own 1,000 shares of our common stock, you will
     receive approximately $460 in cash in exchange for your Predictive
     shares. The exact amount of cash that holders will receive per share of
     Predictive common stock cannot be determined until the closing of the
     merger, but will initially be equal to $19,186,700, divided by the number
     of shares of Predictive common stock and the number of shares of
     Predictive common stock subject to "in-the-money" options outstanding at
     the closing. As of the date hereof, there were an aggregate of __________
     shares of Predictive common stock and shares of Predictive common stock
     subject to "in-the-money" options outstanding (assuming the successful
     completion of our sale of certain assets to Science Applications
     International Corporation, or SAIC, pursuant to which we will reacquire
     4,192,220 shares of our common stock that as a result will no longer be
     outstanding). In addition, the $19,186,700 aggregate consideration will
     be increased if and to the extent our net assets at closing exceed our
     estimates of our net assets at closing set forth in the merger agreement
     by more than $1,250,000, and will be decreased if and to the extent our
     net assets at closing are less than our estimates of our net assets at
     closing set forth in the merger agreement by more than $1,250,000. We do
     not currently anticipate that an adjustment will be required, however,
     several factors, such as our second quarter 2003 results and the timing
     of the closing, may materially impact the assumptions underlying our
     estimates, and may cause them to prove incorrect.

     If the asset sale to SAIC does not occur, we expect the $0.46 initial per
     share consideration to be reduced to approximately $0.42 per share. The
     potential adjustment regarding our closing net assets will apply
     regardless of whether or not the SAIC transaction is consummated.

     We intend to issue a press release no later than three (3) trading days
     prior to the special meeting informing stockholders of what INS and
     Predictive believe to be the final per share purchase price
     determination.

Q:   How does the adjustment to the total consideration work?

A:   We have estimated in the merger agreement that our net assets at closing
     will be $15,386,700. The aggregate consideration to be paid of
     $19,186,700 will be increased if our net assets at closing are greater
     than $16,636,700 by an amount equal to such excess. The aggregate
     consideration to be paid of $19,186,700 will be decreased if our net
     assets at closing are less than $14,136,700 by an amount equal to such
     shortfall. Our net assets at closing for these purposes will be
     calculated generally in accordance with generally accepted accounting
     principles, subject to certain significant exceptions and certain agreed
     upon amounts as set forth on the "Net Asset Determination Schedule"
     attached as Annex D to this proxy statement. The Net Asset Determination
     Schedule contains the detailed procedures by which our net assets will be
     determined at closing. You are encouraged to read the Net Asset
     Determination Schedule in its entirety.

Q:   What do I need to do now?

A:   We urge you to read this proxy statement carefully, including its
     annexes, and to consider how the merger affects you. Then please mail
     your completed, dated and signed proxy card in the enclosed return
     envelope as soon as possible so that your shares can be voted at the
     special meeting of our stockholders.

Q:   How does Predictive's board of directors recommend I vote?

A:   At a meeting held on April 8, 2003, our board of directors unanimously
     determined that the merger is advisable, and in the best interests of,
     Predictive and our stockholders, approved the merger agreement,

                                      iii

     the merger and the other transactions contemplated by the merger
     agreement, and declared that it is in the best interests of Predictive's
     stockholders that you adopt and approve the merger agreement and approve
     the merger on the terms and conditions set forth in the merger agreement.
     The board of directors of Predictive unanimously recommends that you vote
     FOR adoption and approval of the merger agreement and approval of the
     merger.

Q:   What vote of stockholders is required to approve the merger?

A:   For us to complete the merger, stockholders of record on ________, 2003
     holding at least a majority of our shares of outstanding common stock
     must vote "FOR" the merger.

Q:   What happens if I do not return a proxy card?

A:   If you fail to return your proxy card, the effect will be that your
     shares will not be counted for purposes of determining whether a quorum
     is present at the special meeting. In addition, the failure to return
     your proxy card will have the same effect as voting against the merger.

Q:   May I vote in person?

A:   Yes. If your shares are not held in "street name" through a broker or
     bank, you may attend the special meeting of our stockholders and vote
     your shares in person, rather than signing and returning your proxy card.
     If your shares are held in "street name," you must get a proxy from your
     broker or bank in order to attend the special meeting and vote.

Q:   Do I need to attend the special meeting in person?

A:   No. You do not have to attend the special meeting in order to vote your
     Predictive shares. Your shares can be voted at the special meeting of our
     stockholders without attending by mailing your completed, dated and
     signed proxy card in the enclosed return envelope.

Q:   May I change my vote after I have mailed my signed proxy card?

A:   Yes. You may change your vote at any time before your proxy card is voted
     at the special meeting. You can do this in one of three ways. First, you
     can send a written, dated notice to the Secretary of Predictive stating
     that you would like to revoke your proxy. Second, you can complete, date,
     and submit a new proxy card. Third, you can attend the meeting and vote
     in person. Your attendance alone will not revoke your proxy. If you have
     instructed a broker to vote your shares, you must follow directions
     received from your broker to change your instructions.

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

A:   Your broker will not be able to vote your shares without instructions
     from you. You should instruct your broker to vote your shares, following
     the procedures provided by your broker. Without instructions, your shares
     will not be voted, which will have the same effect as a vote against the
     merger.

Q:   Should I send in my Predictive stock certificates now?

A:   No. After the merger is completed, you will receive written instructions
     for exchanging your shares of our common stock for the cash merger
     consideration, without interest, to be received in the merger in exchange
     for outstanding shares of our common stock.

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

A:   We are working toward completing the merger as quickly as possible. We
     expect to complete the merger late in the second calendar quarter of
     2003. In addition to obtaining stockholder approval, we must satisfy all
     other closing conditions.

Q:   What if the proposed merger is not completed?

A:   It is possible that the proposed merger will not be completed. The
     proposed merger will not be completed if, for example, the holders of a
     majority of Predictive common stock do not vote to adopt and approve the
     merger agreement and approve the proposed merger. If the merger is not
     completed, Predictive will continue its current operations and will
     remain a publicly-held company.


                                       iv

Q:   Am I entitled to appraisal rights?

A:   Yes. Holders of our common stock are entitled to appraisal rights under
     the Delaware General Corporation Law, in connection with the merger if
     they meet certain conditions.

Q:   Will I owe taxes as a result of the merger?

A:   The merger will be a taxable transaction for United States federal income
     tax purposes (and also may be taxed under applicable state, local, and
     other tax laws). In general, for United States federal income tax
     purposes, you will recognize gain or loss equal to the difference between
     (1) the amount of cash you receive in the merger for your shares of
     Predictive common stock and (2) the tax basis of your shares of
     Predictive common stock. Refer to the section entitled "The Merger --
     Material United States Federal Income Tax Consequences of the Merger" for
     a more detailed explanation of the tax consequences of the merger. You
     should consult your tax advisor on how specific tax consequences of the
     merger apply to you.

Q:   What other matters will be voted on at the special meeting?

A:   Predictive does not expect to ask its stockholders to vote on any other
     matters at the special meeting.

Q:   Who can help answer my questions?

A:   If you would like additional copies, without charge, of this proxy
     statement or if you have questions about the merger, including the

   This summary highlights selected information from this proxy statement and
may not contain all of the information that is important to you. To understand
the merger fully and for a more complete description of the legal terms of the
merger, you should read carefully this entire proxy statement and the
documents we refer to herein. See "Where You Can Find More Information." The
merger agreement is attached as Annex A to this proxy statement. We encourage
you to read the merger agreement as it is the legal document that governs the
merger.

Forward-Looking Information

   This proxy statement contains "forward-looking statements," as defined in
Section 27A of the Securities Act of 1933, as amended, and Section 21E of the
Securities Exchange Act of 1934, as amended, that are based on our current
expectations, assumptions, estimates and projections about our company and our
industry. The forward-looking statements are subject to various risks and
uncertainties. Generally, these forward-looking statements can be identified
by the use of forward-looking terminology such as "anticipate," "believe,"
"estimate," "expect," "intend," "project," "should," and similar expressions.
Those statements include, among other things, the risk that the aggregate
purchase price will be adjusted downward at closing, the risk that the merger
may not be consummated in a timely manner, if at all, the risk that the SAIC
transaction will not close prior to the closing of the merger, risks regarding
employee retention and other risks detailed in our current filings with the
SEC, including our most recent filing on Form 10-K, which discuss these and
other important risk factors concerning our operations. We caution you that
reliance on any forward-looking statement involves risks and uncertainties,
and although we believe that the assumptions on which our forward-looking
statements are based are reasonable, any of those assumptions could prove to
be inaccurate, and, as a result, the forward-looking statements based on those
assumptions could be incorrect. In light of these and other uncertainties, you
should not conclude that we will necessarily achieve any plans and objectives
or projected financial results referred to in any of the forward-looking
statements. We do not undertake to release the results of any revisions of
these forward-looking statements to reflect future events or circumstances.

Merger Consideration

   If the merger is completed, you will receive approximately $0.46 in cash,
without interest, in exchange for each share of our common stock that you own
The exact amount of cash that holders will receive per share of Predictive
common stock cannot be determined until the closing of the merger as discussed
below and elsewhere in this proxy statement.

   The cash to be received per share of Predictive common stock will initially
be equal to $19,186,700, divided by the number of shares of Predictive common
stock and the number of shares of Predictive common stock subject to "in-the-
money" options outstanding at the closing. As of the date hereof, there were
__________ shares of our common stock outstanding (assuming the successful
completion of our sale of certain assets to Science Applications International
Corporation, or SAIC, pursuant to which we will acquire 4,192,220 shares of
our common stock that as a result will no longer be outstanding), and there
were _________ shares of Predictive common stock subject to "in-the-money"
options outstanding.

   In addition, the $19,186,700 aggregate consideration will be increased if
and to the extent our net assets at closing exceed our estimates of our net
assets at closing set forth in the merger agreement by more than $1,250,000,
and will be decreased if and to the extent our net assets at closing are less
than our estimates of our net assets at closing set forth in the merger
agreement by more than $1,250,000. We do not currently anticipate that an
adjustment will be required, however, several factors, such as our second
quarter 2003 results and the timing of the closing, may materially impact the
assumptions underlying our estimates and cause them to prove incorrect.

   We intend to issue a press release no later than three (3) trading days
prior to the special meeting informing stockholders of what the parties
believe to be the final per share purchase price determination.

   After the merger is completed, you will have the right to receive the merger
consideration but you will no longer have any rights as a Predictive
stockholder. You will receive your portion of the merger consideration after
exchanging your Predictive stock certificates in accordance with the
instructions contained in a letter of transmittal to be sent to you shortly
after completion of the merger.

   See "The Merger -- Merger Consideration."

Adjustment Mechanism

   We have estimated in the merger agreement that our net assets at closing
will be $15,386,700. The aggregate consideration to be paid will be increased
if our net assets at closing are greater than $16,636,700 by the amount of
such excess, and will be decreased if our net assets at closing are less than
$14,136,700 by the amount of such shortfall. Our net assets at closing for
these purposes will be calculated generally in accordance with generally
accepted accounting principles, subject to certain significant exceptions and
certain agreed upon amounts as set forth on the "Net Asset Determination
Schedule" attached as an exhibit to the merger agreement contained in this
proxy statement. The Net Asset Determination Schedule contains the detailed
procedures by which our net assets will be determined at closing. You are
encouraged to read the Net Asset Determination Schedule in its entirety.

   See "The Merger -- Adjustment Mechanism."

Sale of Assets to SAIC

   On April 10, 2003, we entered into an Asset Purchase Agreement with Science
Application International Corporation, or SAIC, whereby we have agreed to sell
to SAIC our Information Sharing and Analysis Centers (ISAC) and Open Source
Intelligence (OSI) services business units in exchange for 4,192,220 shares of
our common stock currently held by SAIC. The merger agreement with INS
specifically permitted us to enter into this agreement, subject to the consent
of INS with respect to certain sections, which consent has been obtained. The
estimated initial consideration of $0.46 per share in the INS merger assumes
the successful closing of the SAIC transaction prior to the closing of the
merger and the reduction of our common stock outstanding by these 4,192,220
shares. If the SAIC transaction does not close prior to the consummation of
the merger, we expect the initial per share consideration in the merger to be
approximately $0.42. The potential adjustment to the total merger
consideration regarding our closing net assets will apply regardless of
whether or not the SAIC transaction is consummated. Although we expect the
closing of the SAIC transaction to be completed prior to the special meeting,
the closing of the SAIC transaction is subject to several conditions, most
importantly the receipt of certain third party consents.

   See "The Merger -- Sale of Assets to SAIC."

Treatment of Awards Outstanding under Predictive's Stock Plans

   Any options that are outstanding immediately prior to the closing and have a
per share exercise price that is less than the per share merger consideration
are referred to as "in-the-money" options. In-the-money options that have not
been exercised prior to the closing shall be amended and automatically
exercised pursuant to a board approved net exercise program. As a result of
this net exercise, holders of in-the-money options who have not exercised such
options prior to the closing will receive at the closing the per share merger
consideration, less any applicable exercise price and withholding taxes. Any
options outstanding at the effective time of the merger that are not in-the-
money will be cancelled. If you exercise options prior to the closing with a
per share exercise price greater than the per share price to be received in
the merger, you will lose money in this transaction.

   See "The Merger -- Effect of Awards Outstanding under Predictive's Stock
Plans."

Market Price and Dividend Data

   Our common stock is listed on The Nasdaq SmallCap Market under the symbol
"PRDS." On April 7, 2003, the last full trading day prior to the public
announcement of the proposed merger, our common stock closed at $0.26. On
_____________, 2003, the last practicable trading day prior to the date of
this proxy statement, our common stock closed at $__. See "Market Price and
Dividend Data."

Material United States Federal Income Tax Consequences of the Merger

   The exchange of shares of our common stock for the cash merger consideration
will be a taxable transaction to our stockholders for United States federal
income tax purposes. See "The Merger -- Material United States Federal Income
Tax Consequences of the Merger."

   Tax matters can be complicated, and the tax consequences of the merger to
you will depend on the facts of your own situation. You should consult your
own tax advisor to fully understand the tax consequences of the merger to you.

Reasons for the Merger

   Our board of directors approved the merger based on a number of positive
factors, including the following:

   o the expected value of the consideration to be received by our
     stockholders in the merger pursuant to the merger agreement, whether or
     not the SAIC transaction closes prior to the closing of the merger;


                                       3

   o the fact that the approximately $0.46 per share expected to be paid as
     the consideration in the merger represents:

     o  a premium of approximately $0.203, or 79.0%, over the trailing average
        closing sales prices for our common stock as reported on the Nasdaq
        SmallCap Market for the one month ended April 7, 2003 of $0.257 per
        share,

     o  a premium of approximately $0.196, or 74.2%, over the trailing average
        closing sales prices for our common stock as reported on the Nasdaq
        SmallCap Market for the one week ended April 7, 2003 of $0.264 per
        share, and

     o  a premium of approximately $0.20, or 76.9%, over the $0.26 closing sale
        price for our common stock as reported on the Nasdaq SmallCap Market on
        April 7, 2003, the trading day prior to our board's approval of the
        merger agreement;

   o the fact that given the expected closing date and our anticipated net
     assets, the board of directors does not currently believe the aggregate
     consideration to be received will be reduced pursuant to the merger
     consideration adjustment;

   o the financial presentation and written opinion of Updata Capital, Inc. to
     our board of directors to the effect that, as of April 8, 2003, and based
     upon and subject to the factors and assumptions set forth in the written
     opinion, the merger consideration to be received by holders of our common
     stock pursuant to the merger agreement, whether or not the SAIC
     transaction is consummated prior to the closing of the merger, is fair
     from a financial point of view to those holders (the full text of this
     opinion, which sets forth the assumptions made, procedures followed,
     matters considered and limitations on the review undertaken by Updata
     Capital in connection with the opinion, is attached as Annex C to this
     proxy statement);

   o the likelihood that the proposed acquisition would be consummated in
     light of the experience, reputation and financial capabilities of INS;

   o the overall fairness of the terms of the merger agreement and related
     documents, including the parties' representations, warranties and
     covenants, and the conditions to their respective obligations, in light
     of the circumstances under which they were negotiated;

   o the fact that pursuant to the merger agreement, we are not prohibited
     from responding (at any time prior to our stockholders' approval and
     adoption of the merger agreement with INS) in the manner provided in the
     merger agreement to certain takeover proposals that our board of
     directors determines in good faith constitute a superior offer, and, upon
     payment of a predetermined termination fee, we may terminate the merger
     agreement under certain circumstances to enter into a superior offer
     transaction;

   o the belief by our board of directors that we obtained the highest price
     per share that INS is willing to pay;

   o the belief by our board of directors that it was unlikely that a third
     party would offer a higher price than INS in the near future after
     considering, among other things, that we or our representatives had
     contacted over 20 other parties concerning the acquisition of Predictive;

   o the historically low trading volume of our stock, the volatility of our
     stock price and the ability of our stockholders to realize liquidity with
     respect to their shares in light of the level of such trading volume and
     volatility;

   o the fact that the merger consideration is all cash, which provides a
     certainty of value to our stockholders compared to a transaction in which
     our stockholders would receive stock;

   o management's assessment that INS has the financial capability to complete
     the merger, in view of the absence of a financing condition in the merger
     agreement and the representation and warranty to that effect made by INS
     in the merger agreement;

   o the view of our board of directors that the merger with INS presented the
     best available option for our stockholders when compared to, and in light
     of, the potential stockholder value that could be expected

                                       4

     to be generated from the other strategic alternatives to the merger
     available to us, including remaining independent and continuing to
     successfully implement our current growth model, the risks and
     uncertainties associated with those alternatives and the uncertain timing
     and likelihood of accomplishing the goals of those alternatives;

   o the fact that Predictive would no longer be subject to the substantial
     compliance, insurance, regulatory and other costs to us of being a public
     company listed on The Nasdaq SmallCap Market, including the additional
     costs associated with complying with the recently enacted Sarbanes-Oxley
     Act upon the closing of the merger;

   o the view of our board of directors, based upon the advice of management
     after consultation with legal counsel, that the regulatory approvals
     necessary to complete the merger could be obtained;

   o the fact that the merger would be subject to the approval of a majority
     of our stockholders and our stockholders, other than our stockholders who
     signed voting agreements, would be free to reject the transaction with
     INS; and

   o the availability of appraisal rights for our stockholders who properly
     exercise their statutory appraisal rights.

   In approving the merger, our board of directors also took into account a
number of negative factors, including the following:

   o risks and contingencies related to the announcement and pendency of the
     merger, the possibility that the merger will not be consummated and the
     potential negative effect of public announcement of the merger in that
     event on our sales, operating results and stock price and our ability to
     retain key management and personnel;

   o the fact that the aggregate merger consideration may be reduced if our
     estimates of our closing net assets prove to be incorrect by more than
     $1,250,000;

   o that our stockholders would not benefit from any potential future
     increase in our value;

   o that, under the terms of the merger agreement and the voting agreements,
     (1) neither we nor the stockholders that signed voting agreements can
     solicit other acquisition proposals, (2) we must pay to INS a termination
     fee and/or reimburse INS for certain of its transaction costs if the
     merger agreement is terminated under certain circumstances, and (3) the
     holders of approximately 28.4% of our common stock have agreed to vote
     for the merger, all of which may deter others from proposing an
     alternative transaction that may be more advantageous to our
     stockholders;

   o the fact that gains from an all-cash transaction would be taxable to our
     stockholders for U.S. federal income tax purposes;

   o that if the merger does not close, our officers and other employees will
     have expended extensive efforts attempting to complete the transaction
     and will have experienced significant distractions from their work during
     the pendency of the transaction and we will have incurred substantial
     transaction costs in connection with the transaction and such costs will
     negatively impact our operating results;

   o the conditions to INS's obligation to complete the merger and the right
     of INS to terminate the merger agreement under certain circumstances; and

   o that certain of our directors and executive officers may have had other
     interests with respect to the merger in addition to their interests as
     stockholders of Predictive generally, as described in "The Merger --
     Interests of Predictive's Directors and Management in the Merger."

   See "The Merger -- Reasons for the Merger and Board of Directors'
Recommendation."

Recommendation to Stockholders

   Our board of directors has unanimously:

   o determined that the merger is advisable, and in the best interests of,
     Predictive and our stockholders;

     merger agreement and approval of the merger.

Recommendation."

Opinion of our Financial Advisor

   Updata Capital, Inc. delivered its opinion to our board of directors that,
as of the date of the written fairness opinion and based upon and subject to
the factors and assumptions set forth in the written opinion, the merger
consideration to be received by holders of our common stock pursuant to the
merger agreement, whether or not the SAIC transaction is completed prior to
the closing of the merger, is fair from a financial point of view to those
holders.

   The full text of the written opinion of Updata Capital, dated April 8, 2003,
which sets forth assumptions made, procedures followed, matters considered and
limitations on the review undertaken in connection with the opinion, is
attached as Annex C to this proxy statement. Our stockholders should read the
opinion in its entirety. Updata Capital provided its opinion for the
information and assistance of our board of directors in connection with its

     agreement at a duly held stockholders meeting;

   o by us, upon the approval of our board of directors, if our board of
     directors concludes in good faith that it is required to terminate the
     merger agreement by its fiduciary duties to our stockholders in
     connection with entering into a definitive agreement with respect to an
     acquisition proposal which qualifies as a superior offer;

   o by either INS or us, if the other party has breached any of its
     representations, warranties, covenants or other agreements contained in
     the merger agreement such that any of the conditions to the merger would
     not be satisfied and such breach cannot be cured within thirty (30)
     calendar days;

   o by INS in the event we materially breach any of the provisions regarding
     solicitation of an acquisition proposal; or

   o by INS if any of the following "triggering events" occurs:

     o  our board of directors or any of its committees for any reason
        withdraws or withholds, or amends, changes or modifies in a manner
        adverse to INS, its unanimous recommendation in favor of the adoption
        and approval of the merger agreement or the approval of the merger,
        subject to limited exceptions;

     o  we fail to include in this proxy statement the unanimous recommendation
        of our board of directors that stockholders vote in favor of and adopt
        and approve the merger agreement and the merger, subject to limited
        exceptions;

     o  our board of directors or any of its committees approves or recommends
        any other acquisition proposal;

     o  we enter into any letter of intent or similar document or any contract
        accepting any other acquisition proposal; or

     o  a tender or exchange offer relating to our securities is commenced by a
        person unaffiliated with INS and we have not sent to our stockholders,
        within ten (10) business days after such a tender or exchange offer is
        first published, sent or given, a statement disclosing that our board
        of directors recommends rejection of such tender or exchange offer.

   See "The Merger Agreement and Voting Agreements -- The Merger Agreement --
Termination."

Expenses and Termination Fees

   The merger agreement provides that regardless of whether the merger is
consummated, all fees and expenses incurred by the parties shall be borne by
the party incurring such expenses.

   The merger agreement requires, however, that we pay INS a termination fee of
$600,000 if, among other things:

   o INS terminates the merger agreement as a result of a "triggering event,"
     as described above;

   o the agreement is terminated by INS or us because our stockholders do not
     approve the merger at the special meeting, and prior to such vote a
     director abstains from a board or board committee vote concerning the
     merger and the director (or any of its affiliates, including Predictive)
     then makes a public statement adverse to INS or the merger;

   o the fiduciary duties of our board of directors require us to terminate
     the merger agreement in connection with our entering into a definitive
     agreement related to an acquisition proposal which qualifies as a
     superior offer;

   o INS terminates the merger agreement because either the effective time has
     not occurred before September 30, 2003 or we failed to obtain the
     required approval of our stockholders, and any of the following occurs:


                                       9

     o  a third party has announced an acquisition proposal and has not
        publicly withdrawn the acquisition proposal at least five (5) business
        days prior to the earlier of September 30, 2003 or the meeting of our
        stockholders to vote on the merger, as may be applicable, and within
        nine (9) months following the termination of our merger agreement with
        INS, an acquisition of us is completed; or

     o  a third party has announced an acquisition proposal and has not
        publicly withdrawn the acquisition proposal at least five (5) business
        days prior to the earlier of September 30, 2003 or the meeting of our
        stockholders to vote on the merger, as may be applicable, and within
        nine (9) months following the termination of our merger agreement with
        INS, we enter into a letter of intent or similar document or contract
        that provides for any acquisition of us.

   In addition to the termination fees described above, in the event INS
terminates the merger agreement in connection with the breach of our
representation and warranty that we have performed or complied in all material
respects with all agreements and covenants required by the merger agreement,
and prior to such termination, we have received, or a third party has
announced, an acquisition proposal and our breach is intended to or has the
effect of facilitating such acquisition proposal or benefiting the person or
entity making such acquisition proposal without similarly benefiting INS, we
will be required to pay INS an amount equal to the out-of-pocket fees and
expenses incurred by INS and Mid-West Acquisition Corporation in connection
with the negotiation, execution and delivery of the merger agreement to which
this proxy solicitation relates, provided, however, that we are not required
to pay INS expenses in excess of $500,000.

   See "The Merger Agreement and Voting Agreements -- The Merger Agreement --
Termination Fee."

Voting Agreements

   All of our executive officers and directors (other than one director who
does not individually own any shares of our common stock or options) and
certain of our affiliates, who owned approximately 28.4% of our outstanding
shares as of April 8, 2003, entered into individual voting agreements with
INS. As of the record date, excluding options to purchase shares of our common
stock, such persons beneficially own approximately __% of the shares entitled
to vote at the special meeting, assuming the successful closing of the asset
sale to SAIC, and ___% of the shares entitled to vote at the special meeting,
assuming the asset sale to SAIC does not close. Pursuant to the voting
agreements, these stockholders have agreed to vote their shares, and have
granted INS an irrevocable proxy to vote their shares, in favor of approval of
the merger and adoption and approval of the merger agreement, and against any
proposal adverse to the merger.

   See "The Merger Agreement and Voting Agreements -- The Merger Agreement --
The Voting Agreements."

Accounting Treatment

   The merger will be accounted for as a "purchase transaction" by INS for
financial accounting purposes. See "The Merger -- Accounting Treatment."

Appraisal Rights

   Subject to compliance with the procedures set forth in Section 262 of the
Delaware General Corporations Law ("DGCL"), holders of record of our common
stock who do not vote in favor of the approval and adoption of the merger
agreement and the merger and otherwise comply with the requirements of
Section 262 of the DGCL are entitled to appraisal rights, in connection with
the merger, whereby such stockholders may receive the "fair value" of their
shares in cash, exclusive of any element of value arising from the expectation
or accomplishment of the merger. Failure to take any of the steps required
under Section 262 of the DGCL, on a timely basis, may result in a loss of
those appraisal rights. These procedures are described in this proxy
statement. The provisions of Delaware law that grant appraisal rights and
govern such procedures are attached as Annex B.

   See "The Merger -- Appraisal Rights."

                              THE SPECIAL MEETING


   We are furnishing this proxy statement to our stockholders as part of the
solicitation of proxies by our board of directors for use at the special
meeting.

Date, Time and Place

   We will hold the special meeting at our headquarters located at 19 West 44th
Street, 9th Floor, New York, New York 10036 at 10:00 a.m., local time, on
____________, ____________, 2003.

Purpose of Special Meeting

   At the special meeting, we will ask holders of our common stock to adopt and
approve the merger agreement and approve the merger. Our board of directors
has unanimously determined that the merger is advisable and in the best
interests of Predictive and our stockholders, approved the merger agreement,
the merger and the other transactions contemplated by the merger agreement,
and declared that it is in the best interests of Predictive's stockholders
that you adopt and approve the merger agreement and approve the merger on the
terms and conditions set forth in the merger agreement. The board of directors
of Predictive unanimously recommends that Predictive's stockholders vote FOR
adoption and approval of the merger agreement and approval of the merger.

Record Date; Stock Entitled to Vote; Quorum

   Only holders of record of our common stock at the close of business on
____________, 2003, the record date, are entitled to notice of and to vote at
the special meeting. On the record date, approximately ____________ shares of
our common stock were issued and outstanding and held by approximately __
holders of record. A quorum is present at the special meeting if a majority of
the shares of our common stock issued and outstanding and entitled to vote on
the record date are represented in person or by proxy. In the event that a
quorum is not present at the special meeting, it is expected that the meeting
will be adjourned or postponed to solicit additional proxies. Holders of
record of our common stock on the record date are entitled to one vote per
share at the special meeting on the proposal to adopt and approve the merger
agreement and approve the merger.

Votes Required

   The adoption and approval of the merger agreement and approval of the merger
requires the affirmative vote of the holders of a majority of the shares of
our common stock outstanding on the record date. If a holder of our common
stock abstains from voting or does not vote, either in person or by proxy, it
will effectively count as a vote against the adoption and approval of the
merger agreement and against approval of the merger.

Voting by Predictive's Directors, Executive Officers and Certain Stockholders

   All of our executive officers and directors (other than one director who
does not individually own any shares of our common stock or options) and
certain of our affiliates, who owned approximately 28.4% of our outstanding
shares as of April 8, 2003, entered into individual voting agreements with
INS. As of the record date, excluding options to purchase shares of our common
stock, such persons beneficially own approximately __% of the shares entitled
to vote at the special meeting, assuming the successful closing of the asset
sale to SAIC, and ___% of the shares entitled to vote at the special meeting,
assuming the asset sale to SAIC does not close. Pursuant to the voting
agreements, these stockholders have agreed to vote their shares, and have
granted INS an irrevocable proxy to vote their shares, in favor of approval of
the merger and adoption and approval of the merger agreement, and against any
proposal adverse to the merger.

Voting of Proxies

   All shares represented by properly executed proxies received in time for the
special meeting will be voted at the special meeting in the manner specified
by the holders. Properly executed proxies that do not

                                       12

contain voting instructions will be voted FOR the adoption and approval of the
merger agreement and approval of the merger.

   Shares of our common stock represented at the special meeting but not
voting, including shares of our common stock for which proxies have been
received but for which stockholders have abstained, will be treated as present
at the special meeting for purposes of determining the presence or absence of
a quorum for the transaction of all business.

   Only shares affirmatively voted for the adoption and approval of the merger
agreement and approval of the merger, including properly executed proxies that
do not contain voting instructions, will be counted as favorable votes for
that proposal. If a holder of our common stock abstains from voting or does
not execute a proxy, it will effectively count as a vote against the adoption
and approval of the merger agreement and against approval of the merger.
Brokers who hold shares of our common stock in street name for customers who
are the beneficial owners of such shares may not give a proxy to vote those
customers' shares in the absence of specific instructions from those
customers. These non-voted shares will effectively count as votes against the
adoption and approval of the merger agreement and against approval of the
merger.

   The persons named as proxies by a stockholder may propose and vote for one
or more adjournments of the special meeting, including adjournments to permit
further solicitations of proxies.

   We do not expect that any matter other than the proposal to adopt and
approve the merger agreement and approve the merger will be brought before the
special meeting. If, however, our board of directors properly presents other
matters, the persons named as proxies will vote in accordance with their
judgment as to matters that they believe to be in the best interests of the
stockholders.

Revocability of Proxies

   The grant of a proxy on the enclosed form of proxy does not preclude a
stockholder from voting in person at the special meeting. A stockholder may
revoke a proxy at any time prior to its exercise by:

   o filing with our Secretary a duly executed revocation of proxy;

   o submitting a duly executed proxy to our Secretary bearing a later date;
     or

   o appearing at the special meeting and voting in person; however,
     attendance at the special meeting will not in and of itself constitute
     revocation of a proxy.

   If you have instructed your broker to vote your shares, you must follow
directions received from your broker to change these instructions.

Solicitation of Proxies

   All costs of solicitation of proxies will be borne by us. We have retained
the services of ____________ to assist in the solicitation of proxies from our
stockholders. The fee to be paid to ______________ for these services is not
expected to exceed $5,000, plus reasonable out of pocket expenses.
Additionally, the directors and officers and employees of Predictive may,
without additional compensation, solicit proxies for stockholders by mail,
telephone, facsimile, or in person. However, you should be aware that certain
members of our board of directors and our executive officers have interests in
the merger that are different from, or in addition to, yours. See "The Merger
-- Interests of Predictive's Directors and Management in the Merger."

   The extent to which these proxy soliciting efforts will be necessary depends
entirely upon how promptly proxies are received. You should send in your proxy
by mail without delay. We also reimburse brokers and other custodians,
nominees and fiduciaries for their expenses in sending these materials to you
and getting your voting instructions.

   Stockholders should not send stock certificates with their proxies. A letter
of transmittal with instructions for the surrender of our common stock
certificates will be mailed to our stockholders as soon as practicable after
completion of the merger.

                                   THE MERGER


   The following discussion summarizes the material terms of the merger.
Stockholders should read the merger agreement, which is attached as Annex A to
this proxy statement.

Background to the Merger

   As part of its long-term strategy to increase stockholder value, our board
of directors and senior management has, from time to time, considered various
strategic transactions with other companies. Similarly, from time to time, our
board of directors and senior management has reviewed various strategic
alternatives, including remaining an independent public company, ceasing
operations, divesting certain operations, consummating acquisitions or mergers
with other companies and considering other transactions.

   In October 2001, our management became aware that Lucent Technologies was in
the process of selling its Enhanced Services and Sales or ESS business unit,
which would eventually become INS.

   From October 2001 through June 2002, our management negotiated with Lucent
for the purchase of the ESS unit, and eventually became a finalist in the
auction process conducted by Lucent. During this process, which included both
negotiating the transaction and planning for the anticipated integration of
the two businesses, our board of directors and senior management became
familiar with the operations of INS and with INS's senior management.
Ultimately, we could not obtain financing for the purchase of ESS and we
ceased discussions.

   In June and July 2002, Mission West Venture Capital, an affiliate of Carl
Berg, worked with Lucent to negotiate the purchase of ESS. At that time, the
officers of ESS and Mr. Berg discussed the possibility that, should ESS be
spun out of Lucent with the backing of Mr. Berg's venture company, the growth
strategies of that business unit might well be served by the subsequent
acquisition of one or more additional consulting or software businesses. In
August 2002, INS was incorporated in Delaware and it concluded the purchase of
ESS from Lucent.

   In July and August 2002, we explored the possibility of selling our European
operations and had discussions with INS regarding this possible sale.

   On September 25, 2002, Andrew Zimmerman, our CEO, David Butze, CEO of INS,
and Montgomery Kersten, Vice President, Business Development of INS met in
person to discuss INS's possible purchase of our European operations. During
this meeting, the advantages of a combination of our operations and INS's
operations were also discussed. On October 4, 2002, we entered into a
confidentiality agreement with INS relating to the sale of our European
operations.

   During October and November 2002, Messrs. Zimmerman, Butze and Kersten,
along with Neeraj Sethi, our CFO, and Gary Papilsky, our General Counsel, had
various discussions about and provided various information regarding our
European operations.

   On October 10, 2002 and November 1, 2002, Mr. Zimmerman discussed a possible
acquisition of Predictive with a large international competitor. These
discussions never materialized into an offer.

   On October 31, 2002, at a regularly scheduled meeting of our board of
directors, Mr. Zimmerman discussed with the board the possible sale of our
European operations to INS. In addition, at this board meeting, Mr. Zimmerman
discussed other strategic alternatives with the board, including the sale of
the company and the sale of certain divisions. Mr. Zimmerman reviewed
potential transaction partners with the board and such potential partners'
expressed or expected level of interest.

   On November 11, 2002, we received a draft term sheet from INS regarding the
sale of our European Operations, and on November 19, 2002, we sent a revised
term sheet to INS highlighting certain issues with respect to the initial
draft. On November 27, 2002, INS sent a revised term sheet to us regarding the
sale of our European Operations, which we subsequently rejected. We then ended
discussions with INS regarding the sale of our European operations.


                                       16

   On December 10, 2002, at a regularly scheduled meeting of our board of
directors, the board discussed in great detail our strategic alternatives. In
particular, the board discussed the acquisition of certain potential targets,
the possibility of being acquired by certain likely acquisition candidates and
the prospects facing us if we remained an independent company. The board
discussed its fiduciary duties with Wilson Sonsini Goodrich & Rosati, P.C.
(Wilson Sonsini), our outside legal counsel, and considered each alternative
with the objective of maximizing shareholder value. Mr. Zimmerman also
specifically discussed merger candidates with whom he or members of the board
had discussions concerning the sale of the company or certain divisions of the
company and the status of these discussions. The board considered hiring a
financial advisory firm to assist us in the sale of the company or certain
divisions.

   During January 2003, Messrs. Zimmerman, Butze, Kersten, Sethi and Papilsky
had numerous discussions regarding the possible acquisition of us by INS. On
January 8, 2003, Mr. Zimmerman flew to California to meet in person with
Messrs. Butze and Kersten. Mr. Zimmerman also met with Carl Berg, INS's
Chairman of the Board of Directors during this trip.

   On January 15, 2003, Predictive received a draft term sheet from INS
regarding the acquisition of Predictive. The term sheet contemplated that our
security consulting business would be sold for cash to a third party and that
INS would then purchase 100% of our outstanding common stock. During the
remainder of January, Messrs. Zimmerman, Butze, Kersten, Sethi and Papilsky
had numerous negotiations regarding the draft term sheet.

   On January 23, 2003, Mr. Zimmerman discussed the possible acquisition of
Predictive with the CEO of a private company competitor.

   On February 4, 2003, at a regularly scheduled meeting of our board of
directors, Wilson Sonsini again discussed the board's fiduciary obligations
and the board approved the engagement of Updata Capital as financial advisor
to explore the sale of our security consulting business and authorized our
officers to negotiate the terms of a potential sale of us to INS.

   On February 6, 2003, we entered into a confidentiality agreement with the
private company competitor.

   On February 10, 2003, we signed an engagement letter with Updata Capital to
sell our security consulting business and to provide a fairness opinion in the
event of the sale of the entire company.

   On February 10, 2003, Messrs. Zimmerman and Sethi discussed with the CEO and
CFO of the private company competitor our financial information. The private
company competitor never submitted a formal offer thereafter to acquire us,
and further discussions did not materialize.

   On February 20, 2003, we amended the confidentiality agreement we had in
place with INS in order to facilitate exchange of further due diligence
regarding the sale of the entire company. In February and March 2003, INS
conducted a due diligence review of us, including a review of our material
contracts and agreements. On February 23, 2003, we received a revised draft
term sheet from INS regarding the acquisition of Predictive.

   On February 27, 2003, Messrs. Zimmerman and Sethi had discussions with a
public company expressing an interest in acquiring Predictive. On February 28,
2003, the interested party notified Predictive of its intention not to pursue
further discussions.

   On March 3 and 4, 2003, Messrs. Butze, Kersten, Zimmerman, Berg and Eric
Meyer, one of our board members, met to discuss the terms of the proposed
acquisition of Predictive.

   On March 10, 2003, we received a draft of the Agreement and Plan of Merger
from Gray Cary Ware & Freidenrich LLP (Gray Cary), INS's legal counsel, which
was also received by Wilson Sonsini. On March 11, 2003, at a special meeting
of our board of directors, Mr. Zimmerman discussed the economic terms of INS's
offer and Mr. Papilsky discussed the legal terms of the draft Agreement and
Plan of Merger that was received on March 10, 2003.

   On March 12, 2003, Mr. Sethi sent due diligence information to a private
equity fund that was considering making a bid for the acquisition of
Predictive. This private equity fund ultimately decided not to submit a
proposal.


                                       17

   From March 12, 2003 through April 8, 2003, Predictive, INS, Wilson Sonsini
and Gray Cary exchanged numerous drafts of the Agreement and Plan of Merger
and had numerous discussions to negotiate its terms, culminating in lengthy
conferences on April 3, 4, 6, 7 and 8, 2003.

   During March 2003, Updata Capital contacted 20 companies in an effort to
receive a competing bid to the INS proposal. The companies contacted were IT
services companies, telecommunications providers and financial sponsors. As a
result of such efforts, only one company entered into a confidentiality
agreement. Following the execution of a confidentiality agreement and the
receipt of due diligence materials, that company notified Updata Capital of
its intention not to pursue further discussions.

   On March 25, 2003, at a regularly scheduled meeting of our board of
directors, our management reviewed the then current economic and legal terms
of INS's proposal for the acquisition of the entire company.

   On April 8, 2003, our board of directors held a special meeting to consider
the proposed merger with INS. Mr. Papilsky and Wilson Sonsini reviewed the
board's fiduciary obligations to its stockholders, as well as the material
changes in the merger agreement since the draft circulated to the board of
directors on April 7, 2003. Updata Capital then presented its financial
analysis relating to the proposed transaction and rendered its opinion to the
board of directors that, as of April 8, 2003, and subject to the assumptions,
factors and limitations set forth in the written opinion, the merger
consideration payable to our stockholders in the proposed transaction was
fair, from a financial point of view, to our stockholders. Following these
presentations, the board of directors further discussed the potential merger,
following which, by a unanimous vote of all directors, our board of directors
determined that the merger was fair to, and in the best interests of,
Predictive and its stockholders, and approved the merger, the merger agreement
and related matters.

   On April 8, 2003, the parties executed the merger agreement and thereafter
issued a joint press release announcing the execution of the merger agreement
and other related matters.

Reasons for the Merger and Board of Directors' Recommendation

   Reasons for the Merger. In the course of reaching its decision to approve
the merger and to adopt and approve the merger agreement, our board of
directors consulted with our senior management, legal counsel and financial
advisor, reviewed a significant amount of information and considered a number
of factors, including, among others, the following factors:

   o our current and historical financial condition and our results of
     operations as a stand-alone company, our prospects and strategic
     objectives, the risks involved in achieving those prospects and
     objectives, the network services industry as a whole, and the current and
     anticipated worldwide economic environment;

   o the possible alternatives to the merger (including the possibility of
     continuing to operate as an independent entity, and the perceived risks
     thereof), the range of possible benefits to our stockholders of such
     alternatives and the timing and the likelihood of accomplishing the goal
     of any of such alternatives, and our board of directors' assessment that
     the merger with INS presented a superior opportunity to such
     alternatives;

   o the then current financial market conditions, and historical market
     prices, volatility and trading information with respect to our common
     stock;

   o other historical information concerning our business, prospects,
     financial performance and condition, operations, technology, management
     and competitive position.

   In the course of its deliberations, our board of directors also considered,
among other things, the following positive factors:

   o the expected value of the consideration to be received by our
     stockholders in the merger pursuant to the merger agreement, whether or
     not the SAIC transaction closes prior to the closing of the merger;

   o the fact that the approximately $0.46 per share expected to be paid as
     the consideration in the merger represents:


                                       18

     o  a premium of approximately $0.203, or 79.0%, over the trailing average
        closing sales prices for our common stock as reported on the Nasdaq
        SmallCap Market for the one month ended April 7, 2003 of $0.257 per
        share,

     o  a premium of approximately $0.196, or 74.2%, over the trailing average
        closing sales prices for our common stock as reported on the Nasdaq
        SmallCap Market for the one week ended April 7, 2003 of $0.264 per
        share, and

     o  a premium of approximately $0.20, or 76.9%, over the $0.26 closing sale
        price for our common stock as reported on the Nasdaq SmallCap Market on
        April 7, 2003, the trading day prior to our board's approval of the
        merger agreement;

   o the fact that given the expected closing date and our anticipated second
     quarter 2003 revenues and working capital needs, the board of directors
     does not believe the aggregate consideration to be received will be
     reduced pursuant to the merger consideration adjustment;

   o the financial presentation and written opinion of Updata Capital, Inc. to
     our board of directors to the effect that, as of April 8, 2003, and based
     upon and subject to the factors and assumptions set forth in the written
     opinion, the merger consideration to be received by holders of our common
     stock pursuant to the merger agreement, whether or not the SAIC
     transaction is consummated prior to the closing of the merger, is fair
     from a financial point of view to those holders (the full text of this
     opinion, which sets forth the assumptions made, procedures followed,
     matters considered and limitations on the review undertaken by Updata
     Capital in connection with the opinion, is attached as Annex C to this
     proxy statement);

   o the likelihood that the proposed acquisition would be consummated, in
     light of the experience, reputation and financial capabilities of INS;

   o the overall fairness of the terms of the merger agreement and related
     documents, including the parties' representations, warranties and
     covenants, and the conditions to their respective obligations, in light
     of the circumstances under which they were negotiated;

   o the fact that pursuant to the merger agreement, we are not prohibited
     from responding (at any time prior to our stockholders' approval and
     adoption of the merger agreement with INS) in the manner provided in the
     merger agreement to certain takeover proposals that our board of
     directors determines in good faith constitute a superior offer, and, upon
     payment of a predetermined termination fee, we may terminate the merger
     agreement under certain circumstances to enter into a superior offer
     transaction;

   o the belief by our board of directors that we obtained the highest price
     per share that INS is willing to pay;

   o the belief by our board of directors that it was unlikely that a third
     party would offer a higher price than INS in the near future after
     considering, among other things, that we or our representatives had
     contacted over 20 other parties concerning the acquisition of Predictive;

   o the historically low trading volume of our stock, the volatility of our
     stock price and the ability of our stockholders to realize liquidity with
     respect to their shares in light of the level of such trading volume and
     volatility;

   o the fact that the merger consideration is all cash, which provides a
     certainty of value to our stockholders compared to a transaction in which
     our stockholders would receive stock;

   o management's assessment that INS has the financial capability to complete
     the merger, in view of the absence of a financing condition in the merger
     agreement and the representation and warranty to that effect made by INS
     in the merger agreement;

   o the view of our board of directors that the merger with INS presented the
     best available option for our stockholders when compared to, and in light
     of, the potential stockholder value that could be expected to be
     generated from the other strategic alternatives to the merger available
     to us, including remaining

                                       19

     independent and continuing to successfully implement our current growth
     model, the risks and uncertainties associated with those alternatives and
     the uncertain timing and likelihood of accomplishing the goals of those
     alternatives;

   o the fact that Predictive would no longer be subject to the substantial
     compliance, insurance, regulatory and other costs to us of being a public
     company listed on The Nasdaq SmallCap Market, including the additional
     costs associated with complying with the recently enacted Sarbanes-Oxley
     Act upon the closing of the merger;

   o the view of our board of directors, based upon the advice of management
     after consultation with legal counsel, that the regulatory approvals
     necessary to complete the merger could be obtained;

   o the fact that the merger would be subject to the approval of a majority
     of our stockholders and our stockholders, other than our stockholders who
     signed voting agreements, would be free to reject the transaction with
     INS; and

   o the availability of appraisal rights for our stockholders who properly
     exercise their statutory appraisal rights.

   In the course of its deliberations, our board of directors also considered,
among other things, the following negative factors:

   o risks and contingencies related to the announcement and pendency of the
     merger, the possibility that the merger will not be consummated and the
     potential negative effect of public announcement of the merger in that
     event on our sales, operating results and stock price and our ability to
     retain key management and personnel;

   o the fact that the aggregate merger consideration may be reduced if our
     estimates of our closing net assets prove to be incorrect by more than
     $1,250,000;

   o that our stockholders would not benefit from any potential future
     increase in our value;

   o that, under the terms of the merger agreement and the voting agreements,
     (1) neither we nor the stockholders that signed voting agreements can
     solicit other acquisition proposals, (2) we must pay to INS a termination
     fee and/or reimburse INS for certain of its transaction costs if the
     merger agreement is terminated under certain circumstances, and (3) the
     holders of approximately 28.4% of our common stock have agreed to vote
     for the merger, all of which may deter others from proposing an
     alternative transaction that may be more advantageous to our
     stockholders;

   o the fact that gains from an all-cash transaction would be taxable to our
     stockholders for U.S. federal income tax purposes;

   o that if the merger does not close, our officers and other employees will
     have expended extensive efforts attempting to complete the transaction
     and will have experienced significant distractions from their work during
     the pendency of the transaction and we will have incurred substantial
     transactions costs in connection with the transaction and such costs will
     negatively impact our operating results;

   o the conditions to INS's obligation to complete the merger and the right
     of INS to terminate the merger agreement under certain circumstances; and

   o that certain of our directors and executive officers may have had other
     interests with respect to the merger in addition to their interests as
     stockholders of Predictive generally, as described in "The Merger --
     Interests of Predictive's Directors and Management in the Merger."

   The preceding discussion of the information and factors considered by our
board of directors is not, and is not intended to be, exhaustive. In light of
the variety of factors considered in connection with its evaluation of the
merger and the complexity of these matters, our board of directors did not
find it practicable to, and did not, quantify or otherwise attempt to assign
relative weights to the various factors considered in reaching its
determination. In addition, our board of directors did not undertake to make
any specific determination as to whether any particular factor, or any aspect
of any particular factor, was favorable or unfavorable to the ultimate
determination of our board of directors, but rather, our board of directors
conducted an overall

                                       20

analysis of the factors described above, including discussions with and
questioning of our senior management and legal and financial advisors.

   Board of Directors Recommendation. After careful consideration, our board
of directors has unanimously determined that the merger is advisable and in
the best interests of Predictive and our stockholders, approved the merger
agreement, the merger and the other transactions contemplated by the merger
agreement, and declared that it is in the best interests of Predictive's
stockholders that you adopt and approve the merger agreement and approve the
merger on the terms and conditions set forth in the merger agreement.
Accordingly, the board of directors of Predictive unanimously recommends that
you vote FOR adoption and approval of the merger agreement and approval of the
merger.

Opinion of Updata Capital, Inc.

   Pursuant to a letter agreement dated as of February 10, 2003, we retained
Updata Capital, Inc. to, among other activities, render an opinion to our
board of directors regarding the fairness of the merger consideration, from a
financial point of view, to our stockholders. We selected Updata Capital to
render a fairness opinion in connection with this transaction based on Updata
Capital's qualifications, reputation, experience, and expertise in providing
investment banking services to its clients in the information technology
sector. At the meeting of our board of directors on April 8, 2003, Updata
Capital delivered its written opinion that, as of that date and based upon and
subject to the various assumptions made, procedures followed, matters
considered and limits of review as set forth in its opinion, the merger
consideration was fair, from a financial point of view, to our stockholders.

   The full text of Updata Capital's written opinion, which describes the
various assumptions made, procedures followed, matters considered and
limitations of review undertaken by Updata Capital, is attached as Annex C to
this document. You are urged to, and should, read the Updata Capital opinion
carefully and in its entirety. The Updata Capital opinion is directed to our
board of directors and addresses only the fairness of the merger
consideration, from a financial point of view, to holders of shares of our
common stock as of the date of the opinion. The Updata Capital opinion does
not address any other aspect of the merger, and does not constitute a
recommendation to any stockholder as to how such stockholder should vote on
the merger. The summary of the Updata Capital opinion set forth in this proxy
statement is qualified in its entirety by reference to the full text of such
opinion.

   In connection with rendering its opinion, Updata Capital:

   o reviewed the terms of the draft of the merger agreement furnished to
     Updata Capital on April 7, 2003;

   o reviewed certain of our publicly available financial statements and other
     public information;

   o participated in certain discussions with our senior management concerning
     certain internal business, financial and operational information
     regarding current and forecasted financial information;

   o compared the proposed financial terms of the offer and certain other
     aspects of our financial performance with other relevant publicly-traded
     companies;

   o compared the proposed financial terms and share price premiums of the
     offer with those of other relevant precedent mergers and acquisitions;

   o reviewed historical market prices and trading activity for our common
     stock and compared them with those of publicly-traded companies in our
     industry;

   o considered the state of information technology, or IT, software and
     services market, including network and security sectors, and the impact
     of the market on our operations;

   o reviewed a liquidation analysis of Predictive provided by our management;
     and

   o considered other financial studies, analyses and investigations as Updata
     Capital deemed appropriate for purposes of its opinion.

   In rendering its opinion, Updata Capital relied, without independent
verification, on the accuracy and completeness of all the financial and other
information, including without limitation the representations and

                                       21

warranties contained in the merger agreement, that was publicly available or
that we furnished to Updata Capital. With respect to the financial forecasts
examined by Updata Capital, Updata Capital assumed that they were reasonably
prepared and reflected the best available estimates of our management as to
our future performance.

   With respect to the liquidation analysis provided by us and examined by
Updata Capital, Updata Capital assumed that the liquidation analysis
accurately reflected the range of values that would be available to be
distributed to stockholders upon liquidation of Predictive. Updata Capital has
not made an independent appraisal or valuation of any of our assets nor does
it assume responsibility for or express any view as to financial forecasts or
the assumptions on which they were based. Updata Capital has not reviewed our
books and records, nor made a physical inspection of our properties or
facilities. Updata Capital assumed that the merger would be consummated on the
terms set forth in the merger agreement, without modification or waiver of any
material terms.

   For purposes of its analyses, Updata Capital assumed the completion of the
sale of our ISAC (the Information Sharing and Analysis Center division and
Open Source Intelligence division) business to Science Applications
International Corporation (SAIC) prior to the closing of the merger for
approximately 4.2 million shares of our common stock. Notwithstanding, Updata
Capital deemed the impact of the sale of the ISAC business to be non-material
to the results of the Updata Capital analysis or the Updata Capital opinion
and therefore the sale to SAIC had no impact on the conclusions contained in
the Updata Capital opinion.

   The Updata Capital opinion is based upon market, economic, financial and
other conditions as they existed and could be evaluated as of April 7, 2003.
Although developments following the date of the Updata Capital opinion may
affect the opinion, Updata Capital assumed no obligation to update, revise or
reaffirm the opinion.

   The following is a summary description of some of the sources of information
and methodologies employed by Updata Capital in rendering its opinion. The
preparation of a fairness opinion involves various determinations as to the
most appropriate and relevant method of financial and comparative analysis and
the application of these methods to the particular circumstances.
Consequently, a fairness opinion is not readily susceptible to summary
description. Updata Capital believes that its analyses must be considered as a
whole and that considering any portions of those analyses and factors without
considering all of them could create a misleading or incomplete view of the
process underlying the opinion. This summary of financial analyses includes
information presented in tabular format, and are based upon the assumption
that we will consummate the sale of the ISAC business. In order to fully
understand the financial analyses used by Updata Capital, 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.

   Implied Transaction Value. Updata Capital calculated an equity value for
Predictive of $19.2 million and an enterprise value for Predictive of negative
$1.4 million, based on an estimation made on April 7, 2003 as to the amount of
consideration payable to the holders of Predictive common stock. Updata
Capital assumed that the final net assets at closing would remain within the
estimated range specified in the merger agreement, and therefore the
adjustment at closing would be zero. The enterprise value was obtained by
adding to the equity value of $19.2 million, our capital lease obligations of
approximately $60,000, and subtracting the amount of our cash and restricted
cash as of December 31, 2003 of $20.6 million, which, for this purpose,
included $21.3 million in cash and restricted cash on the balance sheet,
$1.8 million in proceeds from the expected exercise of options, less
$2.5 million of restructuring reserves. Updata Capital then calculated the
implied valuation multiples by dividing both enterprise value and equity value
by our revenue for the twelve months ended December 31, 2002, for the last
quarter ended December 31, 2002 on an annualized basis, and for the estimated
quarter ending March 31, 2003 on an annualized basis.

   Predictive Stock Performance Analysis. Updata Capital compared our recent
stock performance with that of the Nasdaq Composite and an index comprised of
certain publicly traded companies in the information technology services
industry that Updata Capital deemed relevant. This index consisted of the
following companies: Alphanet Solutions, Braun Consulting, Cysive,
DiamondCluster International, Edgewater Technology, Inforte, Modem Media,
Tanning Technology, and The Management Network Group. Updata Capital noted
that none of the companies used in the stock performance analysis is identical
to Predictive. Updata Capital also noted that our latest twelve month high and
low closing trading prices were $1.54 and $0.17 respectively, and that during
the past 9 months, the stock price traded between $0.17 and $0.50, and the
average closing price was $0.26 per share.

   Comparable Public Company Analysis. Updata Capital compared certain
financial information and valuation ratios relating to Predictive with those
of certain other publicly traded IT services companies that had public market
valuations of less than $100 million, and that had declining revenues during
the past 12 months and negative profitability. Updata Capital noted that the
selected comparable public companies did not represent the entire universe of
potentially relevant IT services companies, and that none of the companies
used in the analysis is identical to Predictive. The companies included were:
Alphanet Solutions, Braun Consulting, DiamondCluster International, Edgewater
Technology, Inforte, Modem Media, Tanning Technology, and The Management
Network Group. Financial information reviewed by Updata Capital included each
company's:

   o market capitalization, or equity value, calculated as the most recent
     closing price multiplied by the current shares outstanding;

   o enterprise value, calculated as the market capitalization of the selected
     company, plus the company's short term and long term debt obligations,
     less the company's cash, cash equivalents, and investments;

   o latest twelve month, or LTM, revenue as reported as of the date of Updata
     Capital's fairness opinion; and

   o annualized run rate revenue for the most recent quarter, or MRQ, as of
     the date of Updata Capital's fairness opinion.

   Updata Capital also compared the comparable companies' multiples for the
quarter ending December 31, 2002, or Q4, with Predictive's expected revenue
for the quarter ending March 31, 2003, or Q1E. Updata Capital noted that the
multiples implied by the proposed offer were within the reference range of
each valuation analysis. The following table presents implied valuation
multiples for the Predictive transaction and reference ranges for the public
company analysis:

   Precedent M&A Transactions. Updata Capital reviewed and compared precedent
merger and acquisition transactions under $100 million in value involving
sellers that shared certain operational and financial characteristics with
Predictive. Updata Capital noted that the selected precedent transactions were
not intended to be representative of the entire range of precedent
transactions in IT consulting. These precedent transactions included: SBI's
acquisition of Razorfish, CIBER's acquisition of ECSoft plc, CGI Group's
acquisition of Cognicase, Progress Software's acquisition of eXcelon, divine's
acquisition of Viant, SBI's acquisition of Lante, Intellimark's acquisition of
Technisource, and Seneca Investment's acquisition of Organic. Financial
information, regarding these transactions, that were reviewed by Updata
Capital included:

   o offer value, or equity value, calculated as the offer price multiplied by
     the current shares outstanding;


                                       23

   o enterprise value, calculated as the offer value of the respective target
     company, plus the company's short term and long term debt obligations,
     less the company's cash, cash equivalents, and investments;

   o LTM revenue as of the date of the respective acquisition; and

   o annualized run rate revenue for the most recent quarter as of the date
     just prior to the announcement of the acquisition.

   Updata Capital also compared the comparable company's multiples for the
quarter ending December 31, 2002, or Q4, with our expected revenue for the
quarter ending March 31, 2003, or Q1E. Estimated multiples paid in the
precedent transactions analysis were based upon information obtained from
public filings and public company disclosures. No transaction utilized as a
comparison is identical to the INS merger transaction. Updata Capital noted
that the multiples implied by the proposed offer were within the reference
range of each valuation analysis. The following table presents implied
valuation multiples for the INS merger and reference ranges for the precedent
M&A analysis:

   Premiums Paid Analysis. Updata Capital considered and reviewed the premium
paid over a company's trading price 1, 5, and 20 trading days prior to the
date of an announced acquisition. Updata Capital analyzed such premiums for
three groups of companies deemed to be relevant with respective to
Predictive's industry sector and financial status including: (i) recent IT
software and services acquisitions under $100 million in equity value; (ii)
recent IT services acquisitions; and (iii) recent IT software and services
acquisitions where the target's net cash balance was at least 80% of the
equity value. Updata Capital noted that the premiums implied by the proposed
offer were within the reference range of each valuation analysis. The
following table presents the implied premium for the merger and reference
ranges for the premiums paid analysis:

   Liquidation Analysis. Updata Capital reviewed the analysis, prepared by our
management, of the per share liquidation value if we were to cease operation
and liquidate our assets as of June 30, 2003 and distribute the remaining cash
to our stockholders. The analysis yielded an estimated range of value between
$0.00 and $0.09 per share. Updata Capital noted that the per share merger
consideration of the offer proposal was in excess of the liquidation analysis
value.


                                       24

   Conclusion. In connection with the review of the merger by our board of
directors, Updata Capital performed a variety of financial and comparative
analyses. The summary set forth above does not purport to be a comprehensive
description of all the analyses and factors considered by Updata Capital. The
preparation of a fairness opinion is a complex process that involves various
determinations as to the most appropriate and relevant methods of financial
analysis and the application of these methods to the particular circumstances
and therefore, such an opinion is not necessarily susceptible to partial
analysis or summary description. In arriving at its opinion, Updata Capital
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. Updata
Capital believes that selecting any portion of its analyses, without
considering all analyses, would create an incomplete view of the process
underlying its opinion. The conclusions reached by Updata Capital may involve
significant elements of subjective judgment and qualitative analysis. In
performing its analyses, Updata Capital considered general economic, market
and financial conditions and other matters, many of which are beyond our
control. The analyses supplied by Updata Capital and its opinion were among
many factors taken into consideration by our board in making its decision to
enter into the Merger Agreement and should not be considered as determinative
of such decision.

   Pursuant to its engagement letter with us, Updata Capital was paid a
retainer fee of $40,000 and will receive a fee for the fairness opinion
rendered to our board of directors in the amount of $150,000, plus the
reimbursement of its reasonable out-of-pocket expenses and fees up to $75,000.
Updata Capital also would have been paid an additonal fee for the separate
sale of our security consulting business, which did not and will not
materialize. We have also agreed to indemnify and hold harmless Updata Capital
and its affiliates and any controlling person, director, employee or agent
acting on behalf of Updata Capital or any of its affiliates for losses,
claims, damages and liabilities relating to or arising out of services
provided by Updata Capital as our financial advisor. The terms of the fee
arrangement with Updata Capital, which we and Updata Capital believe are
customary in transactions of this nature, were negotiated at arm's-length.

Interests of Predictive's Directors and Management in the Merger

   In considering the recommendation of our board of directors in favor of the
merger, you should be aware that members of our board of directors and our
executive officers have interests in the merger that are different from, or in
addition to, your interests.

   All such additional interests are described below, to the extent material,
and except as described below, such persons have, to our knowledge, no
material interest in the merger apart from those of stockholders generally.
Our board of directors was aware of, and considered the interests of, our
directors and executive officers in approving the merger agreement and the
merger.

   Indemnification and Insurance. The merger agreement provides that from and
after the effective time of the merger, INS will and will cause the surviving
corporation to fulfill and honor the obligations of Predictive pursuant to any
indemnification agreements between us and our directors and officers, and any
indemnification provisions under our charter documents in effect as of the
date of the merger agreement. The Certificate of Incorporation and Bylaws of
the surviving corporation will contain provisions with respect to exculpation
and indemnification that are at least as favorable to our directors and
officers as those contained in our charter documents as in effect on the date
of the merger agreement, and such provisions will not be amended, repealed or
otherwise modified for a period of six (6) years from the effective time of
the merger in a manner adverse to such directors and officers unless required
by applicable law. The merger agreement further provides that we will purchase
prior to the closing of the merger, for a price not to exceed a stated amount
set forth in the merger agreement, directors' and officers' liability tail
insurance coverage covering those persons who were, as of the date of the
merger agreement, covered by our directors' and officers' liability insurance
policies, on terms comparable to those in effect on the date of the merger
agreement, and covering all periods prior to the effective time of the merger.

   Bonus Arrangements. The board considered the assistance of our senior
executives integral in entering into the merger agreement and deems the
continued service of these senior executives necessary in order to complete
the merger. To incentivize such executives, and other members of senior
management, to assist us in effecting the merger, the board has established a
bonus program whereby our senior executives and senior

                                       25

management will be entitled to certain payments upon the closing of the
merger. The following table sets forth the aggregate amount to be set aside
and paid pursuant to the bonus program:


                                                                     Total Set Aside
      Merger Consideration Per Share                              Under Bonus Program
      ------------------------------                               -------------------
                                                                
      Less than $0.35..........................................         $150,000
      Between $0.35 and $0.374.................................         $250,000
      Between $0.375 and $0.399................................         $350,000
      Equal to or greater than $0.40...........................         $450,000



   Andrew Zimmerman, our Chief Executive Officer, Neeraj Sethi, our Chief
Financial Officer, Gary Papilsky, our General Counsel, Shirley Howell, our
Executive Vice President of Operations and Edward Schwartz, our Executive Vice
President - Global Integrity Services, are our senior executives eligible to
participate in the bonus program. Mr. Zimmerman, subject to board approval,
will determine the percentage each eligible senior executive or other member
of senior management will receive of the total amount subject to the bonus
program.

   Employment Offers. Mr. Schwartz and Ms. Howell have been offered employment
after the closing with INS. Mr. Schwartz has been offered the position of
INS's Vice President, Business Development. His compensation pursuant to this
offer letter will be $125,000 per annum, plus an additional $14,666 per month
for a three-month period subject to active employment, with the ability to
receive a bonus of $125,000 contingent on the achievement of to be determined
performance targets. Mr. Schwartz also will receive a non-recoverable draw on
bonus/commissions of $4,166 per month for the first six months of employment.
Mr. Schwartz will also be entitled, upon commencement of employment with INS,
to receive options to purchase 125,000 shares of INS common stock with an
exercise price equal to the fair market value on the date of grant. The
options will vest over a period of four years in even monthly installments,
conditioned on Mr. Schwartz's continued employment with INS.

   Ms. Howell has been offered the position of INS's Vice President, Southern
Region. Her compensation pursuant to this offer letter will be $185,000 per
annum, plus an additional $15,417 per month for a six-month period subject to
active employment. Ms. Howell will also be entitled, upon commencement of
employment with INS, to receive options to purchase 175,000 shares of INS
common stock with an exercise price equal to the fair market value on the date
of grant. The options will vest over a period of four years in even monthly
installments, conditioned on Ms. Howell's continued employment with INS. On
October 1, 2003, the offer letter provides that Ms. Howell's salary will be
reduced to $135,000 per annum, but she will be entitled to a bonus of $125,000
contingent upon the achievement of to be determined performance targets.

   In addition, Mr. Papilsky will remain employed by INS after the closing to
assist in the transition period for a duration of approximately one month
(subject to extension upon mutual consent), on terms substantially similar to
those currently in place for Mr. Papilsky.

   Severance Arrangements. We previously entered into employment agreements
with the executive officers listed below. In the event that any of such
officers are terminated without cause upon a change of control, the employment
agreements provide for severance payments, as well as continued health
coverage at our expense, to each officer equal to the amount set forth next to
the terminated officer's name. Our executive officers who have such
arrangements in place are:



Name                               Severance Payment                                         Health Coverage
----                               ------------------------------------------------------    --------------------------------------
                                                                                       
Andrew Zimmerman                   equal to 12 months salary                                 12 months health coverage
Neeraj Sethi                       equal to 12 months salary                                 6 months heath coverage
Shirley Howell                     equal to 9 months salary                                  6 months health coverage
Gary Papilsky                      equal to 9 months salary                                  6 months health coverage
Edward Schwartz                    equal to 6 months salary                                  6 months health coverage



   Other than Shirley Howell and Edward Schwartz, we do not expect these
executive officers to be retained on a permanent basis by INS after the
merger. The termination of the employment of such officers will be deemed a
termination without "cause" in connection with a change in control, and as a
result these officers will be entitled to receive the aforementioned severance
payments and health coverage.

   Option and Restricted Sale Acceleration. In connection with the closing of
the merger, all unvested options and restricted stock held by our directors
and employees, including our executive officers, will accelerate and be
exercisable in full at the closing. In addition, in-the-money options will
automatically be exercised on behalf of the holders thereof that have not been
exercised prior to the closing pursuant to a board approved net exercise
program. As a result of this net exercise, holders of in-the-money options,
including directors and executive officers, who have not exercised such
options prior to the closing of the

                                       26

merger will receive at the closing the per share merger consideration, less
any applicable exercise price and withholding taxes.

Appraisal Rights

   If the merger is consummated, dissenting holders of our common stock who
follow the procedures specified in Section 262 of the Delaware General
Corporate Law within the appropriate time periods will be entitled to have
their shares of our common stock appraised by a court and to receive the "fair
value" of such shares in cash as determined by the Delaware Court of Chancery
in lieu of the consideration that such stockholder would otherwise be entitled
to receive pursuant to the merger agreement.

   Stockholders who properly perfect appraisal rights or dissenters' rights and
who do not subsequently withdraw such appraisal rights or dissenters' rights
(the "Electing Stockholders") will not be entitled to surrender their shares
of our common stock for payment in the manner otherwise provided in the merger
agreement and described in this proxy statement.

   THE FOLLOWING SUMMARY OF APPRAISAL RIGHTS UNDER DELAWARE LAW IS QUALIFIED IN
ITS ENTIRETY BY REFERENCE TO THE RELEVANT CODE SECTIONS OF DELAWARE, WHICH IS
ATTACHED HERETO AS ANNEX B.

   FAILURE TO STRICTLY FOLLOW THE PROCEDURES SETFORTH IN SUCH CODE SECTIONS MAY
RESULT IN THE LOSS, TERMINATION OR WAIVER OF APPRAISAL RIGHTS. PREDICTIVE
STOCKHOLDERS WHO VOTE TO APPROVE AND ADOPT THE MERGER AGREEMENT WILL NOT HAVE
A RIGHT TO HAVE THEIR SHARES OF OUR COMMON STOCK APPRAISED. A STOCKHOLDER WHO
DESIRES TO EXERCISE HIS, HER OR ITS APPRAISAL RIGHTS MUST ALSO SUBMIT A
WRITTEN DEMAND FOR PAYMENT OF THE FAIR VALUE OF OUR COMMON STOCK HELD BY HIM
OR HER TO US PRIOR TO THE SPECIAL MEETING. THIS PROXY STATEMENT CONSTITUTES
NOTICE TO HOLDERS OF COMMON STOCK CONCERNING THE AVAILABILITY OF APPRAISAL
RIGHTS UNDER SECTION 262.

   Predictive stockholders considering seeking appraisal rights under Delaware
law should note that they could receive a value for their shares that is more,
the same or less than the consideration they would receive pursuant to the
merger agreement if they did not seek appraisal. The costs of the appraisal
proceeding may be determined by the court and taxed against the parties as the
court deems equitable under the circumstances. PREDICTIVE STOCKHOLDERS
CONSIDERING EXERCISING APPRAISAL RIGHTS SHOULD CONSULT WITH THEIR OWN TAX
ADVISORS WITH REGARD TO THE TAX CONSEQUENCES OF SUCH ACTIONS.

   At the effective time of the merger, the shares of our common stock held by
an Electing Stockholder will be canceled, and such stockholder will be
entitled to no further rights except the right to receive payment of the fair
value of such holder's shares. However, if a stockholder fails to perfect or
withdraws or loses his or her appraisal rights with respect to his or her
shares of our common stock, such holder's shares will not be purchased by us
as set forth below, and such holder will receive the applicable merger
consideration in exchange for his or her our common stock under the terms of
the merger agreement.

   Holders of our common stock who demand the appraisal of such holders' shares
and who do not vote in favor of the merger are entitled to certain appraisal
rights under the DGCL in connection with the merger. Such holders who perfect
their appraisal rights and follow the procedures in the manner prescribed by
the DGCL will be entitled to have their shares converted into the right to
receive from us such consideration as may be determined by the Court of
Chancery (the "Court") to be due pursuant to the DGCL. Any stockholder who
wishes to demand appraisal rights, or who wishes to preserve his or her right
to do so, should review this section carefully, since failure to comply with
the procedures set forth in Section 262 of the DGCL will result in the loss of
such rights.

   REFERENCE IS MADE TO SECTION 262 OF THE DGCL, A COPY OF WHICH IS ATTACHED TO
THIS PROXY STATEMENT AS ANNEX B, FOR A COMPLETE STATEMENT OF THE APPRAISAL
RIGHTS OF DISSENTING STOCKHOLDERS. THE FOLLOWING INFORMATION IS QUALIFIED IN
ITS ENTIRETY BY REFERENCE TO THAT SECTION.


                                       27

   A demand for appraisal must be executed by or for the stockholder of record,
fully and correctly, as such stockholder's name appears on the share
certificate. An authorized agent, including an agent for two or more joint
owners, may execute the demand for appraisal for a stockholder of record;
however, the agent must identify the record owner and expressly disclose the
fact that, in exercising the demand, he is acting as agent for the record
owner. A person having a beneficial interest in our common stock held of
record in the name of another person, such as a broker or nominee, must act
promptly to cause the record holder to follow the steps summarized below and
in a timely manner to perfect whatever appraisal rights the beneficial owners
may have.

   A written demand for appraisal rights must be filed with us before the
special meeting. Each stockholder who elects to exercise appraisal rights
should mail or deliver his, her or its written demand to us at our address c/o
Predictive Systems, Inc., 19 West 44th Street, 9th Floor, New York, NY 10036,
Attention: Legal. The written demand for appraisal should specify the
stockholder's name and mailing address, and that the stockholder is thereby
demanding appraisal of his, her or its common stock. Within ten days after the
effective time of the merger, we must provide notice of the effective time of
the merger to all of our stockholders who have complied with Section 262 and
have not voted for the merger.

   At any time within 60 days after the effective date of the merger, any
stockholder who has delivered a written demand to us shall have the right to
withdraw such written demand for appraisal and to accept the terms of the
merger agreement. After this period, a stockholder may withdraw his, her or
its written demand for appraisal and receive payment for his, her or its
shares as provided in the merger agreement only with our consent.

   Within 120 days after the effective time of the merger (but not thereafter),
any stockholder who has satisfied the requirements of Section 262 may deliver
to us a written demand for a statement listing the aggregate number of shares
not voted in favor of the merger and with respect to which demands for
appraisal have been received and the aggregate number of holders of such
shares. We, as the surviving corporation in the merger, must mail such written
statement to the stockholder no later than the later of ten days after the
stockholder's request is received by us or ten days after the latest date for
delivery of a demand for appraisal under Section 262.

   Within 120 days after the effective date of the merger, the surviving
corporation or any Electing Stockholder who is entitled to appraisal rights
may file a petition with the Court demanding a determination of the value of
the stock of all such Electing Stockholders. We have no present intention to
file such a petition if demand for appraisal is made. Note that if no petition
is filed within the allotted time, then the right of the Electing Stockholder
to an appraisal may cease.

   At the hearing on such petition, the Court shall determine the stockholders
who are entitled to an appraisal of their shares and may require the
stockholders who have demanded appraisal to submit their certificates to the
Register in Chancery. Failure to comply may result in a dismissal of the
proceedings as to such stockholder. After determining the stockholders
entitled to an appraisal, the Court shall appraise the shares, determining
their fair market value exclusive of any element of value arising from the
accomplishment or expectation of the merger, together with a fair rate of
interest, if any. The Court shall direct the payment of the fair market value
of the shares, together with interest, if any, by the surviving corporation to
the stockholders entitled thereto.

   To the extent that there are any inconsistencies between the foregoing
summary and Section 262 of the DGCL, the DGCL shall control.

Accounting Treatment

   The merger will be accounted for as a "purchase transaction" by INS for
financial accounting purposes.

Form of the Merger

   Subject to the terms and conditions of the merger agreement and in
accordance with Delaware law, at the effective time of the merger, Mid-West
Acquisition Corporation, a wholly owned subsidiary of INS and a

                                       28

party to the merger agreement, will merge with and into us. We will survive
the merger as a wholly-owned Delaware subsidiary of INS.

Merger Consideration

   At the effective time of the merger, each outstanding share of our common
stock, other than treasury shares, shares held by INS or Mid-West Acquisition
Corporation, shares held by any direct or indirect wholly-owned subsidiary
belonging to us or INS and those shares held by stockholders who perfected
their appraisal rights (as described in "The Merger -- Appraisal"), will be
canceled and automatically converted into the right to receive the merger
consideration of approximately $0.46 in cash, without interest. Treasury
shares, shares held by INS or Mid-West Acquisition Corporation and shares held
by our or INS's wholly-owned subsidiaries will be canceled immediately prior
to the effective time of the merger.

   The exact amount of cash that holders will receive per share of Predictive
common stock cannot be determined until the closing of the merger, but will
initially be equal to $19,186,700, divided by the number of shares of
Predictive common stock and the number of shares of Predictive common stock
subject to "in-the-money" options outstanding at the closing. As of the date
hereof, there were __________ shares of our common stock outstanding (assuming
the successful completion of our sale of certain assets to Science
Applications International Corporation, or SAIC, pursuant to which we will
acquire 4,192,220 shares of our common stock that as a result will no longer
be outstanding), and there were _________ shares of Predictive common stock
subject to "in-the-money" options outstanding. In addition, the $19,186,700
aggregate consideration will adjusted based on our net assets at closing as
described under "The Merger - Adjustment Mechanism" below.

Adjustment Mechanism

   We have estimated in the merger agreement that our net assets at closing
will be $15,386,700. The initial aggregate consideration of $19,186,700 to be
paid will be increased if our net assets at closing are greater than
$16,636,700 by an amount equal to such excess. The aggregate initial
consideration to be paid will be decreased if our net assets at closing are
less than $14,136,700 by an amount equal to such shortfall. Our net assets at
closing for these purposes will be calculated generally in accordance with
generally accepted accounting principles, subject to certain significant
exceptions and certain agreed upon amounts as set forth on the "Net Asset
Determination Schedule" attached as Annex D to this proxy statement. The Net
Asset Determination Schedule contains the detailed procedures by which our net
assets will be determined at closing. You are encouraged to read the Net Asset
Determination Schedule in its entirety.

   We do not currently anticipate that an adjustment will be necessary based on
our net assets. However, an adjustment may be necessary, and the expected
price per share may be reduced, if our estimates of our net assets prove to be
incorrect. Factors that may result in our estimates being incorrect include,
but are not limited to, a material delay in the expected closing date, a
significant decline in our revenues during the second quarter of 2003, the
incurrence of unexpected costs and expenses, and an inability to collect
accounts receivable.

   We intend to issue a press release no later than three (3) trading days
prior to the special meeting informing stockholders of what the parties
believe to be the final per share purchase price determination.

   As of the effective time of the merger, all shares of our common stock will
no longer be outstanding and will automatically be canceled and will cease to
exist and each holder of a certificate representing any shares of our common
stock (other than stockholders who have perfected their appraisal rights) will
cease to have any rights as a stockholder, except the right to receive the
merger consideration. The aggregate price of $19,186,700, as such amount may
be increased or decreased pursuant to the merger consideration adjustment, was
determined through arm's-length negotiations between INS and us.

Sale of Assets to SAIC

   On April 10, 2003, we entered into an Asset Purchase Agreement with Science
Application International Corporation, or SAIC, whereby we have agreed to sell
to SAIC our Information Sharing and Analysis Centers

                                       29

(ISAC) and Open Source Intelligence (OSI) services business units in exchange
for 4,192,220 shares of our common stock currently held by SAIC. The merger
agreement with INS specifically permitted us to enter into this agreement,
subject to the consent of INS with respect to certain sections, which consent
has been obtained. The estimated initial consideration of $0.46 per share to
be received in the INS merger assumes the successful closing of the SAIC
transaction prior to the closing of the merger and the reduction of our common
stock outstanding by these 4,192,220 shares. While we expect the SAIC
transaction to close prior to the consummation of the merger, if it does not,
we expect the initial per share consideration to be approximately $0.42. The
potential adjustment regarding our closing net assets will apply regardless of
whether or not the SAIC transaction is consummated. The closing of the SAIC
transaction is independent of, and not conditioned on, the closing of the
merger with INS. However, the closing of the SAIC transaction is subject to
several other important conditions, including that:

   o the representations and warranties made by us under the asset purchase
     agreement are true and correct in all material respects as of the
     closing;

   o we perform and comply in all material respects with the covenants
     contained in the asset purchase agreement;

   o we obtain third party consents to assign certain contracts to which the
     ISAC and OSI business units are a party, and

   o certain key employees shall have accepted employment with SAIC.

Conversion of Shares; Procedures for Exchange of Certificates

   The conversion of our common stock into the right to receive the merger
consideration will occur automatically at the effective time of the merger. As
soon as reasonably practicable after the effective time of the merger, U.S.
Stock Transfer Corporation, or another paying agent reasonably acceptable to
us, will send a letter of transmittal to each former Predictive stockholder.
The letter of transmittal will contain instructions for obtaining cash in
exchange for shares of our common stock. You should not return stock
certificates with the enclosed proxy.

   Upon surrender of a stock certificate representing shares of our common
stock, together with a duly completed and validly executed letter of
transmittal, and any other documents that may be reasonably required by the
paying agent, the holder of the certificate will be entitled to receive from
the paying agent, on behalf of INS, as promptly as practicable in accordance
with the paying agent's customary procedures, the per share merger
consideration for each share represented by the stock certificate, and the
corresponding stock certificate will be cancelled.

   In the event of a transfer of ownership of our common stock that is not
registered in our stock transfer books, the merger consideration for shares of
our common stock may be paid to a person other than the person in whose name
the surrendered certificate is registered if:

   o the certificate is properly endorsed or otherwise is in proper form for
     transfer, and

   o the person requesting such payment:

     o pays any transfer or other taxes resulting from the payment to a person
       other than the registered holder of the certificate; or

     o establishes to INS or any of its agents that the tax has been paid or
       is not applicable.

   No interest will be paid or accrue on any cash payable upon the surrender of
stock certificates representing shares of our common stock. The cash paid upon
conversion of shares of our common stock will be issued in full satisfaction
of all rights relating to the shares of our common stock.

Effect on Awards Outstanding under Predictive's Stock Plans

   Stock Options. "In-the-money" options that have not been exercised prior to
the closing shall be amended and automatically exercised pursuant to a board
approved net exercise program. As a result of this

                                       30

net exercise, holders of in-the-money options who have not exercised such
options prior to the closing of the merger will receive at the closing the per
share merger consideration, less any applicable exercise price and withholding
taxes. As a result of the merger, any options outstanding at the effective
time of the merger that are not in-the-money will be cancelled. If you
exercise any options with a per share exercise price greater than the merger
consideration to be paid in the merger, you will lose money in connection with
this transaction.

   Employee Stock Purchase Plan. Under the merger agreement, we are required
to terminate the Employee Stock Purchase Plan no later than May 1, 2003. As of
April 30, 2003, all offering and purchase periods under way shall be
terminated, and all outstanding purchase rights shall be immediately exercised
by applying the accumulated payroll deductions for each participant to
purchase shares of our common stock. The purchase price for each participant
will be equal to the lower of 85% of (a) the fair market value per share of
our common stock on such participant's offering date and (b) the fair market
value per share of our common stock on the purchase date. Any excess payroll
deductions not used to purchase shares of our common stock will be returned to
the participant without the payment of any interest.

Effective Time of the Merger

   The merger will become effective upon the filing of a certificate of merger
with the Delaware Secretary of State or at such later time as is agreed upon
by INS and us and specified in the certificate of merger. The filing of the
certificate of merger will occur on the closing date of the merger, which will
not be later than the second business day after satisfaction or waiver of the
conditions to the completion of the merger described in the merger agreement
or at such other time as agreed to by INS and us.

Delisting and Deregistration of Predictive's Common Stock

   If the merger is completed, our common stock will no longer be traded on The
Nasdaq SmallCap Market and will be deregistered under the Securities Exchange
Act of 1934.

Material United States Federal Income Tax Consequences of the Merger

   General. The following describes the material U.S. federal income tax
consequences of the merger that are generally applicable to U.S. holders of
Predictive common stock. However, this discussion does not address all aspects
of taxation that may be relevant to particular U.S. holders in light of their
particular circumstances or to persons who are subject to special treatment
under the U.S. federal income tax laws. This discussion deals only with U.S.
holders that hold shares of Predictive common stock as capital assets within
the meaning of the Internal Revenue Code of 1986, as amended. In addition,
this discussion does not address the tax treatment of special classes of U.S.
holders, such as banks, insurance companies, tax-exempt entities, financial
institutions, broker-dealers, persons, if any, holding Predictive common stock
as "qualified small business stock," persons holding Predictive common stock
as part of a hedging, "straddle," conversion or other integrated transaction,
U.S. expatriates, or persons subject to the alternative minimum tax. This
discussion may not be applicable to stockholders who acquired Predictive
common stock pursuant to the exercise of options or warrants or otherwise as
compensation. Furthermore, this discussion does not address any aspect of
state, local or foreign tax considerations. We urge you to consult your own
tax advisor as to the specific tax consequences of the merger, including the
applicable federal, state, local and foreign tax consequences to you of the
merger.

   As used in this proxy statement, a "U.S. holder" means a holder of
Predictive common stock who is for U.S. federal income tax purposes:

   o a citizen or resident of the United States;

   o a corporation, partnership, or other entity created or organized in the
     United States or under the law of the United States or any state within
     the United States;

   o an estate whose income is includible in gross income for U.S. federal
     income tax purposes, regardless of its source; or


                                       31

   o a trust whose administration is subject to the primary supervision of a
     U.S. court and that has one or more U.S. persons who have the authority
     to control all substantial decisions of the trust.

   This discussion is based on the Internal Revenue Code of 1986, applicable
Department of Treasury regulations, judicial authority, and administrative
rulings and practice, all as of the date of this proxy statement. Future
legislative, judicial, or administrative changes or interpretations may
adversely affect the accuracy of the statements and conclusions described in
this proxy statement. Any changes or interpretations could be applied
retroactively and could affect the tax consequences of the merger to U.S.
holders.

   Consequences of the Merger to Predictive Stockholders. The receipt of cash
in exchange for Predictive common stock in the merger will be a taxable
transaction for U.S. federal income tax purposes. In general, a U.S. holder
will recognize capital gain or loss equal to the difference between the amount
of cash received and the U.S. holder's tax basis in the Predictive common
stock exchanged in the merger. Gain or loss will be calculated separately for
each block of shares, with each block of shares consisting of shares acquired
at the same cost in a single transaction. Such gain or loss will be long-term
capital gain or loss if the U.S. holder held the Predictive common stock for
more than one year as of the effective time of the merger. Certain limitations
apply to the deductibility of capital losses by U.S. holders.

   Federal Income Tax Backup Withholding. A stockholder may be subject to
backup withholding at the rate of 30% with respect to a payment of cash in the
merger unless the stockholder:

   o is a corporation or comes within certain other exempt categories
     (including financial institutions, tax-exempt organizations and non-U.S.
     stockholders) and, when required, demonstrates this fact; or

   o provides a correct taxpayer identification number and certifies, under
     penalties of perjury, that the U.S. stockholder is not subject to backup
     withholding, and otherwise complies with applicable requirements of the
     backup withholding rules.

   To prevent backup withholding and possible penalties, U.S. holders should
complete and sign the substitute Form W-9 included in the letter of
transmittal which will be sent to you if the merger is completed. Foreign
stockholders should complete Internal Revenue Service Form W-8 BEN or other
applicable form. Any amount withheld under these rules may be credited against
the stockholder's U.S. federal income tax liability, provided the required
information is furnished to the Internal Revenue Service.

   We strongly urge you to consult your own tax advisor as to the specific tax
consequences to you of the merger, including the applicability and effect of
U.S. Federal, state, local and foreign income and other tax laws, in view of
your particular circumstances.

Regulatory Matters

   Notifications and antitrust reviews may be required in one or more
jurisdictions. While we do not anticipate any such requirements, the parties
are currently evaluating the need for such notifications and reviews. Those
material to the completion of the merger will be effected as soon as possible.
It is possible that any of the governmental entities with which filings are
required may seek, as conditions for granting approval of the merger, various
regulatory concessions. There can be no assurance that INS or we will be able
to satisfy or comply with these conditions or be able to cause our respective
subsidiaries to satisfy or comply with these conditions, or that the required
regulatory approvals will be obtained within the time frame contemplated by
INS and us or on terms that will be satisfactory to INS and us. See "The
Merger and Voting Agreements -- The Merger Agreement -- Conditions to the
Completion of the Merger."

Employee Matters and Continuation of Predictive's Employee Benefits

   The merger agreement provides that effective no later than the day
immediately preceding the effective time of the merger, Predictive shall
terminate all of its group severance, separation or salary continuation plans,
programs or arrangements and any and all Section 401(k) plans. However, INS
has agreed that as soon as practicable after the effective time of the merger,
it will provide the employees of Predictive and its subsidiaries who remain
employed with INS with substantially the same types and levels of compensation
and employment benefits as those provided by us prior to the merger, subject
to limited exceptions.


                                       32

                   THE MERGER AGREEMENT AND VOTING AGREEMENTS


The Merger Agreement

   The following description summarizes the material provisions of the merger
agreement. Stockholders should read carefully the merger agreement in its
entirety, which is attached as Annex A to this proxy statement.

   Conditions to the Completion of the Merger. Neither party will be obligated
to effect the merger unless the following conditions are satisfied or, to the
extent legally permitted, waived:

   o the holders of a majority of the outstanding shares of our common stock
     must have voted in favor of adoption and approval of the merger agreement
     and approval of the merger;

   o no statute, rule, regulation, executive order, decree, injunction or
     other order, whether temporary, preliminary or permanent, that has the
     effect of making the merger illegal or otherwise preventing the
     completion of the merger shall have been enacted, issued, promulgated,
     enforced or entered by any governmental entity;

   o no action, suit claim or proceeding shall be pending or threatened which
     seeks to materially delay or prevent the consummation of the merger; and

   o no order suspending the use of this proxy statement may be issued and no
     proceeding to suspend the use of this proxy statement shall have been
     initiated or threatened in writing by the SEC.

   We will not be obligated to effect the merger unless the following
conditions are satisfied or waived:

   o the representations and warranties of INS and Mid-West Acquisition
     Corporation must be true and correct as of the date of the merger
     agreement and as of the closing date of the merger, subject to certain
     exceptions; and

   o each of INS and Mid-West Acquisition Corporation must have performed or
     complied in all material respects with all agreements and covenants
     required by the merger agreement at or prior to the closing of the
     merger.

   INS will not be obligated to effect the merger unless the following
conditions are satisfied or waived:

   o our representations and warranties must be true and correct as of the
     date of the merger agreement and as of the closing date of the merger,
     subject to certain exceptions;

   o we must have performed or complied in all material respects with all
     agreements and covenants required by the merger agreement at or prior to
     the closing of the merger;

   o no material adverse effect with respect to us and our subsidiaries shall
     have occurred since the date of the merger agreement;

   o we receive consents to assign a certain real estate lease to INS;

   o at least 80% of certain specified employees shall have accepted
     employment with INS; and

   o no more than 80% of certain specified customers, and none of a specified
     subgroup of such customers, shall have given notice or other indication
     that they wish to:

     o substantially modify in an adverse fashion the terms and conditions
       under which we perform work for such customers, in the case of
       customers billed on a time and materials basis, or

     o terminate or modify in an adverse fashion the terms and conditions of a
       fixed price project to which the customers have previously committed,
       in the case of customers billed on a fixed price basis.

   Material Adverse Effect. Several of our representations and warranties
contained in the merger agreement are qualified by reference to whether the
item in question is reasonably likely to have a "material adverse effect" on
us. In addition, INS will not be required to close the merger if we suffer a
"material

                                       33

adverse effect" prior to the closing. The merger agreement provides that a
"material adverse effect" means any change, event, violation, inaccuracy,
circumstance or effect, individually or when aggregated with other changes,
events, violations, inaccuracies, circumstances or effects, that is materially
adverse to the business, assets (including intangible assets), liabilities,
properties, financial condition or results of operations of the entity and its
subsidiaries, taken as a whole, or the ability of any entity to perform its
obligations under the merger agreement and timely complete the transactions
contemplated by the merger agreement. However, none of the following will be
deemed, by itself or in combination, to constitute, and none of the following
will be taken into account in determining whether there has been or will be a
material adverse effect on us:

   o any change in the market price or trading volume of our common stock;

   o any failure by us to meet internal projections or forecasts or published
     revenue or earnings predictions for any period ending (or for which
     revenues or earnings are released) on or after the date of the merger
     agreement;

   o any adverse change, event, violation, inaccuracy, circumstance or effect:

     o that we successfully prove results from, or is attributable to,
       conditions affecting the industries in which we participate, the United
       States economy as a whole, or foreign economies where we or any of our
       subsidiaries have material operations or sales (where such changes do
       not, in each case, disproportionately affect us or any of our
       subsidiaries);

     o resulting from our compliance with the terms of, or the taking of any
       action required by, the merger agreement;

   o any voluntary termination of the employment of our employees by such
     employees; or

   o the termination, cancellation, deferral or other adverse modification of
     any customer contracts.

   No Solicitation. We have agreed, subject to certain exceptions arising out
of fiduciary duties of our board of directors, that we will not, and will not
permit any of our subsidiaries to, nor will we authorize or permit any of our
or our subsidiaries' officers, directors, affiliates or employees or any of
our or their investment bankers, attorneys, accountants or other advisors or
representatives retained by us or them, to, directly or indirectly:

   o solicit, initiate, knowingly or intentionally encourage, facilitate or
     induce the making, submission or announcement of any other acquisition
     proposal;

   o participate in any negotiations or discussions regarding, or furnish to
     any person any non-public information with respect to, or take any other
     action to facilitate any inquiries or the making of any proposal that
     constitutes or may reasonably be expected to lead to, any other
     acquisition proposal;

   o approve, endorse or recommend any other acquisition proposal; or

   o enter into any letter of intent or similar document or any contract
     contemplating or otherwise relating to any other acquisition transaction.

   The merger agreement does provide that our board of directors may enter into
a confidentiality agreement with and provide confidential information to, or
enter into negotiations or discussions with, any person or group in response
to an acquisition proposal submitted and not withdrawn by such person or
group, if:

   o neither we nor our subsidiaries nor any of our or their representatives
     have violated the restrictions set forth above;

   o our board of directors concludes in good faith, after consultation with
     our outside legal counsel, that the action is required in order for the
     board of directors to comply with its fiduciary duties to our
     stockholders under applicable law;

   o at least two (2) business days prior to providing any nonpublic
     information to, or entering into negotiations or discussions with, such
     person or group, we give INS written notice of the identity of

                                       34


     the person or group and of our intention to furnish nonpublic information
     to, or enter into negotiations or discussions with, such person or group;

   o we receive from such person or group an executed confidentiality
     agreement containing limitations on the use and disclosure of all
     nonpublic written and oral information provided by us to such person or
     group, with limitations which are no less favorable to us than those in
     the confidentiality agreement entered into with INS; and

   o contemporaneously with providing any nonpublic information to such person
     or group, we provide such nonpublic information to INS.

   The merger agreement provides that the term "acquisition proposal" means any
offer or proposal (other than an offer or proposal by INS or Mid-West
Acquisition Corporation) relating to any transaction or series of related
transactions involving:

   o any acquisition or purchase from us by any person or group (as defined
     under Section 13(d) of the Exchange Act and the rules and regulations
     thereunder) of more than a fifteen percent (15%) interest in our total
     outstanding voting securities, or that of any of our subsidiaries;

   o any tender offer or exchange offer that if consummated would result in
     any person or group (as defined under Section 13(d) of the Exchange Act
     and the rules and regulations thereunder) beneficially owning fifteen
     percent (15%) or more of our total outstanding voting securities, or that
     of any of our subsidiaries;

   o any merger, consolidation, business combination or similar transaction
     involving us pursuant to which our stockholders immediately preceding
     such a transaction would hold less than eighty five percent (85%) of the
     equity interests in the surviving or resulting entity of such a
     transaction;

   o any sale, lease, exchange, transfer, license (other than in the ordinary
     course of business and consistent with our past practices), acquisition
     or disposition of more than fifteen percent (15%) of our assets; or

   o any liquidation or dissolution of us.

   The merger agreement provides that our board of directors may amend, change,
withdraw or modify its unanimous recommendation in favor of the merger at any
time prior to our stockholders' approval and adoption of the merger agreement
and approval of the merger, but only to terminate the merger agreement in
accordance with the termination procedures described below under the sub-
heading "Termination," and only if:

   o a superior offer (as described below) is made to us and is not withdrawn,
     and, concurrent with the termination of the merger agreement our board of
     directors causes us to enter into a definitive agreement with respect to
     such a superior offer;

   o neither we nor any of our subsidiaries nor any of our or their
     representatives have violated any of the restrictions regarding
     solicitation set forth above in connection with such superior offer; and

   o our board of directors concludes in good faith, after consultation with
     our outside legal counsel, that in light of such superior offer, the
     withdrawal, amendment, change or modification of its recommendation is
     required in order for it to comply with its fiduciary duties to our
     stockholders under applicable law.

   The merger agreement provides that the term "superior offer" means any
unsolicited, bona fide written offer made by a third party to consummate any
acquisition proposal on terms that our board of directors determines, in its
reasonable judgment (after consultation with a reputable financial advisor) to
be more favorable to our stockholders from a financial point of view than the
terms of the merger with INS. However, any such offer will not be deemed to be
a "superior offer" if any financing required to complete the transaction
contemplated by such an offer is not committed and is not likely in the
reasonable judgment of our board of directors to be obtained by such third
party on a timely basis.

   Termination. The merger agreement may be terminated at any time prior to
the effective time of the merger under certain circumstances, including:


                                       35

   o by mutual written consent authorized by the boards of directors of INS
     and us;

   o by either INS or us, if the merger has not been completed by September 30,
     2003 for any reason, provided, however, that this right to terminate the
     merger agreement will not be available to a party whose action or failure
     to act was a principal cause of, or resulted in, the failure of the
     merger to be completed by September 30, 2003, and such action or failure
     to act constituted a breach of the merger agreement;

   o by either INS or us, if any governmental entity issues any final and
     nonappealable order, decree or ruling or any other action having the
     effect of permanently restraining, enjoining or otherwise prohibiting the
     merger;

   o by either INS or us, if our stockholders do not approve the merger
     agreement at a duly held stockholders meeting, provided, however, that
     the right to terminate the merger agreement for the failure to obtain the
     required approval of our stockholders will not be available to us where
     such failure was caused by our action or failure to act and our action or
     failure to act constitutes a breach by us of the merger agreement;

   o by us, upon the approval of our board of directors, if our board of
     directors concludes in good faith that it is required to terminate the
     merger agreement by its fiduciary duties to our stockholders under
     applicable law, after consultation with our outside legal counsel, in
     connection with entering into a definitive agreement with respect to an
     acquisition proposal which qualifies as a superior offer;

   o by either INS or us, if the other party has breached any of its
     representations, warranties, covenants or other agreements contained in
     the merger agreement, or if any representation or warranty has become
     untrue, in either case such that any of the conditions to the merger
     would not be satisfied as of the time of the breach or as of the time
     such representation or warranty became untrue and has not been, or is
     incapable of being, cured within thirty (30) calendar days after written
     notice of such breach or failure;

   o by INS in the event we materially breach any of the provisions regarding
     solicitation relating to an acquisition proposal; or

   o by INS if any of the following "triggering events" occurs:

     o our board of directors or any of its committees for any reason
       withdraws or withholds, or amends, changes or modifies in a manner
       adverse to INS, its unanimous recommendation in favor of the adoption
       and approval of the merger agreement or the approval of the merger;

     o we fail to include in this proxy statement the unanimous recommendation
       of our board of directors that stockholders vote in favor of and adopt
       and approve the merger agreement and the merger;

     o our board of directors or any of its committees approves or recommends
       any other acquisition proposal;

     o we enter into any letter of intent or similar document or any contract
       accepting any other acquisition proposal; or

     o a tender or exchange offer relating to our securities is commenced by a
       person unaffiliated with INS and we have not sent to our stockholders,
       within ten (10) business days after such a tender or exchange offer is
       first published, sent or given, a statement disclosing that our board
       of directors recommends rejection of such tender or exchange offer.

   For all purposes of the merger agreement, the recommendation of the board
shall be deemed to continue to be "unanimous" despite an abstention by one or
more directors subsequent to the date of the merger agreement on any vote by
the members of the board if:

   o such abstention does not affect the due and valid recommendation of the
     board with respect to the merger;


                                       36

   o no abstaining board member (or any affiliate thereof) makes any public
     statement with respect to the abstention, either explicitly or
     implicitly, in a manner adverse to INS nor any public statement
     reasonably likely to have an adverse effect on the stockholder vote; and

   o subject to limited exception, no abstention in any way or fashion affects
     INS's rights and our obligations with respect to the maintenance, and the
     manner of maintenance, of the board's unanimous recommendation.

   Termination Fee. The merger agreement requires that we pay INS a
termination fee of $600,000, if, among other things:

   o INS terminates the merger agreement as a result of a triggering event, as
     described above;

   o the agreement is terminated by INS or us because our stockholders do not
     approve the merger at the special meeting, and prior to such vote a
     director abstains from a board or board committee vote concerning the
     merger and the director (or any of its affiliates, including Predictive)
     then makes a public statement adverse to INS or the merger;

   o the fiduciary duties of our board of directors requires us to terminate
     the merger agreement in connection with our entering into a definitive
     agreement related to an acquisition proposal which qualifies as a
     superior offer;

   o INS terminates the merger agreement because either the effective time has
     not occurred before September 30, 2003 or we failed to obtain the
     required approval of our stockholders, and any of the following occurs

     o a third party has announced an acquisition proposal and has not
       publicly withdrawn the acquisition proposal at least five (5) business
       days prior to the earlier of September 30, 2003 or the meeting of our
       stockholders to vote on the merger, as may be applicable, and within
       nine (9) months following the termination of our merger agreement with
       INS, an acquisition of us is completed; or

     o a third party has announced an acquisition proposal and has not
       publicly withdrawn the acquisition proposal at least five (5) business
       days prior to the earlier of September 30, 2003 or the meeting of our
       stockholders to vote on the merger, as may be applicable, and within
       nine (9) months following the termination of our merger agreement with
       INS, we enter into a letter of intent or similar document or contract
       that provides for any acquisition of us.

   In addition to the termination fees described above, in the event INS
terminates the merger agreement in connection with the breach of our
representation and warranty that we have performed or complied in all material
respects with all agreements and covenants required by the merger agreement,
and prior to such termination, we have received, or a third party has
announced, an acquisition proposal and our breach is intended to or has the
effect of facilitating such acquisition proposal or benefiting the person or
entity making such acquisition proposal without similarly benefiting INS, we
will be required to pay INS an amount equal to the out-of-pocket fees and
expenses incurred by INS and Mid-West Acquisition Corporation in connection
with the negotiation, execution and delivery of the merger agreement to which
this proxy solicitation statement relates, provided, however, that we are not
required to pay INS expenses in excess of $500,000.

   Conduct of Business Pending the Merger. Under the merger agreement, we have
agreed that prior to the earlier of the termination of the merger agreement or
the effective time of the merger, subject to certain exceptions, unless we
obtain INS's written consent (which consent or refusal to grant consent may
not be unreasonably withheld or delayed) we will and will cause each of our
subsidiaries to, carry on our and their businesses in the usual, regular and
ordinary course in substantially the same manner as conducted up until now and
in compliance with all applicable laws and regulations, pay our liabilities
and taxes when due, pay or perform other obligations when due, and use
commercially reasonable efforts consistent with past practices to preserve our
and their present business organization, keep available the services of our
and their present officers and employees and preserve our and their
relationships with customers, suppliers, distributors, consultants, licensors,
licensees and others having significant business dealings with us and them. In
addition, we have agreed that, among other things and subject to certain
exceptions, neither we nor any of our

                                       37

   In addition to the foregoing, during the period between our initial delivery

   o any other liabilities except in the ordinary course of business
     consistent with past practice or in connection with the transactions
     contemplated by the merger agreement, and

   o any liabilities of the kind that would be contained in the closing net
     assets schedule whatsoever, except for those liabilities consistent with,
     and not exceeding, the liabilities as set forth in the closing net assets
     schedule.

   Business Promotion Program. The merger agreement provides that, to the
extent permitted by law, we will develop a "launch plan" with INS to promote
the benefits and improved capabilities of the combined company to our
customers and employees. We are not required to incur any additional expenses
in complying with the plan other than ordinary travel expenses.

   Reasonable Efforts. Except as otherwise limited by the terms of the merger
agreement, we and INS have each agreed to use our commercially reasonable
efforts to take all actions and to do and to assist and

                                       39

cooperate with the other parties in doing all things necessary, proper or
advisable to complete the merger, including using reasonable efforts to
accomplish the following:

   o taking all reasonable actions necessary to satisfy the conditions to the
     merger;

   o obtaining all necessary actions or nonactions, waivers, consents,
     approvals, orders and authorizations from governmental entities;

   o making all necessary registrations, declarations and filings (including
     registrations, declarations and filings with governmental entities, if
     any) and taking all reasonable steps as necessary to avoid any suit,
     claim, action, investigation or proceeding by any governmental entities;

   o obtaining all consents, approvals or waivers from third parties required
     as a result of the merger;

   o defending any suit, claim, action, investigation or proceeding, whether
     judicial or administrative, challenging the merger and the merger
     agreement, including seeking to have any stay or temporary restraining
     order entered by any court or other governmental entity vacated or
     reversed; and

   o executing and delivering any additional documents reasonably necessary to
     complete the merger and to fully carry out the purposes of the merger
     agreement.

   However, the merger agreement does not require INS or us to:

   o agree to divest any shares of capital stock or of any business, assets or
     property of INS or any of its subsidiaries or affiliates or any shares of
     capital stock or of any business, assets or property of us or any of our
     subsidiaries or affiliates; or

   o agree to the imposition of any material limitation on the ability of INS
     or us to conduct our businesses or to own or exercise control over our
     assets, properties and stock.

   Amendment; Extension and Waiver. The parties may amend the merger agreement
at any time, before or after stockholder approval has been obtained, by the
execution of a writing signed by INS and us. However, if the merger agreement
is to be amended after stockholder approval has been obtained, no amendment
will be allowed that by law requires further approval by stockholders of the
parties without the further approval of those stockholders.

   At any time prior to the effective time of the merger, the parties may:

   o extend the time for the performance of any of the obligations or other
     acts of the other party to the merger agreement;

   o waive any inaccuracies in the representations and warranties of the other
     party contained in the merger agreement or in any document delivered
     pursuant to the merger agreement; or

   o waive compliance by the other party with any of the agreements or
     conditions contained in the merger agreement.

   However, after stockholder approval has been obtained, no waiver may be made
that by law requires further approval of those stockholders without the
further approval of those stockholders. Any extensions or waivers must be in
writing and any delays in exercising any right under the merger agreement will
not constitute a waiver of such right.

   Expenses. The merger agreement provides that regardless of whether the
merger is consummated, all fees and expenses incurred by the parties shall be
borne by the party incurring such expenses.

   Representations and Warranties. The merger agreement contains customary
representations and warranties relating to, among other things:

     and us;

The Voting Agreements

   In order to induce INS to enter into the merger agreement, all of our
executive officers and directors (other than one director who does not
individually own any shares of our common stock or options) and certain of our
affiliates, who beneficially owned approximately 28.4% of our outstanding
shares as of April 8, 2003, entered into individual voting agreements with
INS. Pursuant to the voting agreements, these stockholders have agreed to vote
their shares of our capital stock in favor of adoption and approval of the
merger agreement and approval of the merger, and against any proposal adverse
to the merger. These stockholders have also agreed to irrevocably appoint the
members of the board of directors of INS as their lawful attorneys and
proxies. These proxies give INS the limited right to vote the shares of our
capital stock beneficially owned by these stockholders, including shares of
our capital stock acquired by these stockholders after the date of the voting
agreement, in favor of the adoption and approval of the merger agreement and
approval of the merger, and against any proposal adverse to the merger. These
stockholders may vote their shares of our capital stock on all other matters.

   None of the stockholders who are parties to the voting agreements were paid
additional consideration in connection with entering a voting agreement.
However, you should be aware that certain of these stockholders are members of
our board of directors and/or executive officers, and they may have interests
in the merger that are different from, or in addition to, yours. See "The
Merger -- Interests of Predictive's Directors and Management in the Merger."


                                       42

   Pursuant to the voting agreements, each stockholder who is a party agreed
not to sell shares of our capital stock and options owned, either directly or
indirectly, by such stockholder until the earlier of the termination of the
merger agreement or the effective time of the merger.

   These voting agreements will terminate upon the earlier of the termination
of the merger or the effective time of the merger. The substantial form of
voting agreement is attached to this proxy statement as Annex E and you are
encouraged to read it in its entirety.


                                       43

   Schedule, the Adjustment Amount, the Total Consideration and the Merger
   Consideration upon the acceptance and approval by Parent of the Final Net
   Assets Schedule, which Parent shall be obligated to so accept and approve to

   liabilities except in the ordinary course of business consistent with past
   practice or in connection with the transactions contemplated by this
   Agreement, and (B) notwithstanding the allowances in clause (A) immediately
   in the foregoing, any liabilities of the kind that would be contained in the
   Final Net

                                      A-3

   Assets Schedule whatsoever, except for those liabilities consistent with,
   and not exceeding, the liabilities as set forth in the Final Net Assets
   Schedule.

   (g) Stock Options.

      (i) Immediately following the Effective Time, each outstanding option to
   purchase Shares (a "Company Stock Option") issued pursuant to Company stock
   plans or other agreements or arrangements, whether vested or unvested, shall
   be automatically cancelled and terminated and of no further force or effect,
   and the holder thereof shall receive no consideration in connection with
   such cancellation and termination.

      (ii) Company shall take all necessary actions (including providing all
   required notices) to ensure that all outstanding Company Stock Options and
   all Company stock option plans (including without limitation the 1999 Stock
   Incentive Plan, Synet Service Corporation 1996 Stock Option Plan, and Global
   Integrity Corporation 1998 Stock Incentive Plan) are terminated immediately
   following the Effective Time. For each holder of any Company Stock Option,
   the parties shall take steps to enable the holder thereof to exercise the
   option (including any portion that first becomes exercisable in connection
   with the Merger) prior to the Effective Time.

   (h) [Intentionally Omitted.]

   (i) Employee Stock Purchase Plan. On or before May 1, 2003 (the "ESPP
Date") all offering and purchase periods under way under Company's 1999
Employee Stock Purchase Plan (the "ESPP"), shall be terminated and, as of the
date of this Agreement, no new offering or purchase periods shall be
commenced. Company shall take all necessary action, including providing all
required notices to participants, to ensure that the rights of participants in
the ESPP with respect to any such offering or purchase periods shall be
determined by treating the ESPP Date as the last day of such offering and
purchase periods. Company shall take all actions as may be necessary in order
to freeze the rights of the participants in the ESPP, effective as of the date
of this Agreement, to existing participants and, to the extent permissible
under the ESPP, existing participation levels.

   1.7 Dissenting Shares.

   (a) Notwithstanding any provision of this Agreement to the contrary, Shares
that are outstanding immediately prior to the Effective Time and that are held
by stockholders who shall have not voted in favor of the Merger or consented
thereto in writing and who shall have demanded properly in writing appraisal
for such Shares in accordance with Section 262 of Delaware Law (collectively,
the "Dissenting Shares") shall not be converted into, or represent the right
to receive, the Merger Consideration. Such stockholders shall instead be
entitled to receive payment of the appraised value of such Shares held by them
in accordance with the provisions of such Section 262, except that all
Dissenting Shares held by stockholders who shall have failed to perfect or who
effectively shall have withdrawn or lost their rights to appraisal of such
Shares under such Section 262 shall thereupon be deemed to have been converted
into, and to have become exchangeable for, as of the Effective Time, the right
to receive the Merger Consideration, without any interest thereon, upon
surrender, in the manner provided in Section 1.8 hereof, of the certificate or
certificates that formerly evidenced such Shares.

   (b) The Company shall give Parent (i) prompt notice of any demands for
appraisal received by the Company, withdrawals of such demands, and any other
instruments served pursuant to Delaware Law and received by the Company and
(ii) the opportunity to direct all negotiations and proceedings with respect
to demands for appraisal under Delaware Law. The Company shall not, except
with the prior written consent of Parent, make any payment with respect to any
demands for appraisal or offer to settle or settle any such demands.

   1.8 Surrender of Certificates.

   (a) Paying Agent. Prior to the Effective Time, Parent shall select a bank
or trust company reasonably acceptable to the Company to act as agent (the
"Paying Agent") for the holders of Shares to receive the funds to which
holders of Shares shall become entitled pursuant to Section 1.6(c) hereof.
Until the Effective Time, such funds shall be invested by the Paying Agent as
directed by Parent and in such a way to ensure

                                      A-4

such funds are sufficient at the Effective Time to satisfy Parent's
obligations hereunder with respect to the Total Consideration.

   (b) Payment Procedures. Promptly after the Effective Time, Parent shall
cause the Paying Agent to mail to each holder of record (as of the Effective
Time) of a certificate or certificates (the "Certificates"), which immediately
prior to the Effective Time represented the outstanding Shares converted into
the right to receive the Merger Consideration, (i) a letter of transmittal in
customary form (which shall specify that delivery shall be effected, and risk
of loss and title to the Certificates shall pass, only upon delivery of the
Certificates to the Paying Agent and shall contain such other provisions as
Parent may reasonably specify) and (ii) instructions for use in effecting the
surrender of the Certificates in exchange for the Merger Consideration. Upon
surrender of Certificates for cancellation to the Paying Agent or to such
other agent or agents as may be appointed by Parent, together with such letter
of transmittal, duly completed and validly executed in accordance with the
instructions thereto, the holders of such Certificates formerly representing
the Shares shall be entitled to receive in exchange therefor the Merger
Consideration and the Certificates so surrendered shall forthwith be canceled.
Until so surrendered, outstanding Certificates shall be deemed from and after
the Effective Time, for all corporate purposes, to evidence only the right to
receive the respective Merger Consideration. As promptly as practicable
following surrender of any such Certificates, the Paying Agent shall deliver
to the record holders thereof, without interest, the Merger Consideration.

   (c) Payments with respect to Unsurrendered Shares; No Liability. At any
time following the 180th day after the Effective Time, the Surviving
Corporation shall be entitled to require the Paying Agent to deliver to it any
funds which had been made available to the Paying Agent and not disbursed to
holders of Shares (including, without limitation, all interest and other
income received by the Paying Agent in respect of all funds made available to
it), and, thereafter, such holders shall be entitled to look to the Surviving
Corporation (subject to abandoned property, escheat and other similar laws)
only as general creditors thereof with respect to any cash that may be payable
upon due surrender of the Certificates held by them. Notwithstanding the
foregoing, neither Parent, the Surviving Corporation nor the Paying Agent
shall be liable to any holder of a Share for any cash delivered in respect of
such Share to a public official pursuant to any abandoned property, escheat or
other similar law.

   (d) Transfers of Ownership. If the payment of the cash is to be paid to a
person other than the person in whose name the Certificates surrendered in
exchange therefor are registered, it will be a condition of payment that the
Certificates so surrendered be properly endorsed and otherwise in proper form
for transfer (including without limitation, if requested by Parent or the
Paying Agent, a medallion guarantee), and that the persons requesting such
payment will have paid to Parent or any agent designated by it any transfer or
other taxes required by reason of the payment of the cash to a person other
than the registered holder of the Certificates surrendered, or established to
the satisfaction of Parent or any agent designated by it that such tax has
been paid or is not applicable.

   (e) Required Withholding. Each of the Paying Agent, Parent and the
Surviving Corporation shall be entitled to deduct and withhold from any
consideration payable or otherwise deliverable pursuant to this Agreement to
any holder or former holder of the Shares such amounts as may be required to
be deducted or withheld therefrom under the Code or under any provision of
state, local or foreign tax law or under any other applicable legal
requirement. To the extent such amounts are so deducted or withheld, such
amounts shall be treated for all purposes under this Agreement as having been
paid to the person to whom such amounts would otherwise have been paid.

   1.9 No Further Ownership Rights in Shares. Payment of the cash pursuant to
Section 1.6 shall be deemed to have been paid in full satisfaction of all
rights pertaining to the Shares, and there shall be no further registration of
transfers on the records of the Surviving Corporation of the Shares which were
outstanding immediately prior to the Effective Time. If, after the Effective
Time, Certificates are presented to the Surviving Corporation for any reason,
they shall be canceled and exchanged as provided in this ARTICLE I.

   1.10 Lost, Stolen or Destroyed Certificates. In the event that any
Certificates shall have been lost, stolen or destroyed, the Paying Agent shall
pay in exchange for such lost, stolen or destroyed Certificates, upon the
making of an affidavit of that fact by the holder thereof, the cash payable
under the terms hereunder and with respect thereto; provided, however, that
Parent may, in its discretion and as a condition precedent to

                                      A-5

the payment of such cash, require the owner of such lost, stolen or destroyed
Certificates to deliver a bond in such reasonable and customary amount as it
may direct as indemnity against any claim that may be made against Parent, the
Surviving Corporation or the Paying Agent with respect to the Certificates
alleged to have been lost, stolen or destroyed.

   1.11 Taking of Necessary Action; Further Action. If, at any time after the
Effective Time, any further action is necessary or desirable to carry out the
purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges,
powers and franchises of the Company and Merger Sub, the officers and
directors of the Company and Merger Sub will take all such lawful and
necessary action.


                                   ARTICLE II
                   REPRESENTATIONS AND WARRANTIES OF COMPANY

only to such exceptions as are specifically disclosed in writing in the
disclosure schedule supplied by the Company to Parent dated as of the date
hereof and certified by a duly authorized officer of the Company (the "Company
Schedule"), as follows; provided, however, that the Company Schedule shall be
arranged in paragraphs corresponding to the numbered and lettered paragraphs
contained in this Article II and any other paragraph where it is reasonably
and objectively clear that the disclosure is intended to apply to such other
paragraph.

   2.1 Organization and Qualification; Subsidiaries.

   (a) Each of the Company and its subsidiaries is a corporation duly
organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation and has the requisite corporate power and
authority to own, lease and operate its assets and properties and to carry on
its businesses as they are now being conducted. Each of the Company and its
subsidiaries is in possession of all franchises, grants, authorizations,
licenses, permits, easements, consents, certificates, approvals and orders
("Approvals") necessary to own, lease and operate the properties it purports
to own, operate or lease and to carry on its businesses as they are now being
conducted, except where the failure to have such Approvals would not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect on the Company (as defined in Section 9.3(c) hereof).

   (b) The Company has no subsidiaries except for the corporations identified
in Section 2.1(b) of the Company Schedule. Section 2.1(b) of the Company
Schedule also sets forth the form of ownership and percentage interest of the
Company in its subsidiaries and, to the extent that a subsidiary set forth
thereon is not wholly owned by the Company, lists the other persons or
entities who have an interest in such subsidiary and sets forth the percentage
of each such interest. Except as set forth in Section 2.1(b) of the Company
Schedule, neither the Company nor any of its subsidiaries has agreed to make
nor is obligated to make nor is bound by any written or oral agreement,
contract, subcontract, lease, mortgage, indenture, understanding, arrangement,
instrument, note, bond, option, warranty, purchase order, license, sublicense,
insurance policy, benefit plan, pensions, franchise or other instrument,
obligation or commitment or undertaking of any nature (a "Contract"), in
effect as of the date hereof or as may hereafter be in effect under which it
may become obligated to make, any future investment in or capital contribution
to any other entity. Except as set forth in Section 2.1(b) of the Company
Schedule, neither the Company nor any of its subsidiaries directly or
indirectly owns any equity or similar interest in or any interest convertible,
exchangeable or exercisable for, any equity or similar interest in, any
corporation, partnership, limited liability company, joint venture or other
business, association or entity.

   (c) The Company and each of its subsidiaries is duly qualified to do
business as a foreign corporation, and is in good standing, under the laws of
all jurisdictions where the character of the properties owned, leased or
operated by it or the nature of its activities makes such qualification
necessary, except where failures to be so qualified and in good standing would
not reasonably be expected to have a Material Adverse Effect on the Company.


                                      A-6

in the aggregate, prevent or materially delay consummation of the Transactions
or otherwise prevent Parent or Merger Sub from performing their material
obligations under this Agreement.

   3.5 Proxy Statement. The information supplied by Parent and Merger Sub for
inclusion in the Proxy Statement shall not, at the date the Proxy Statement is
first mailed to stockholders of the Company, at the time of the Stockholders'
Meeting or at the Effective Time, contain any untrue statement of a material
fact, or omit to state any material fact required to be stated therein or
necessary in order to make the statements therein, in light of the
circumstances under which they were made, not false or misleading, or
necessary to correct any statement in any earlier communication with respect
to the solicitation of proxies for the Stockholders' Meeting which shall have
become false or misleading. Notwithstanding the foregoing, Parent and Merger
Sub make no representation or warranty with respect to any information
supplied by the Company or any of its representatives for inclusion in the
Proxy Statement.

   3.6 Financing. Parent will have at the Effective Time sufficient cash or
cash-equivalent funds available to permit Merger Sub to consummate the
Transactions, including, without limitation, acquiring all the outstanding
Shares in the Merger.

                             ADDITIONAL AGREEMENTS


   5.1 Proxy Statement; Board Recommendation.

   (a) As promptly as practicable after the execution of this Agreement, the
Company shall prepare and file the Proxy Statement with the SEC under the
Exchange Act. Parent shall provide promptly to the Company such information
concerning itself as, in the reasonable judgment of the Company or its
counsel, may be required or appropriate for inclusion in the Proxy Statement,
or in any amendments or supplements thereto. The Company shall respond to any
comments of the SEC, and shall use its commercially reasonable efforts to have
the Proxy Statement cleared by the SEC as promptly as practicable after such
filing, and the Company shall cause the Proxy Statement to be mailed to its
stockholders at the earliest practicable time after the Proxy Statement is
cleared by the SEC. The Company shall notify Parent promptly upon the receipt
of any comments from the SEC or its staff and of any request by the SEC or its
staff for amendments or supplements to the Proxy Statement or for additional
information and shall supply Parent with copies of all correspondence between
the Company or any of its representatives, on the one hand, and the SEC or its
staff, on the other hand, with respect to the Proxy Statement or the Merger.
The Company shall give Parent and its counsel the opportunity to review the
Proxy Statement, including all amendments and supplements thereto, prior to
its being filed with the SEC and shall give Parent and its counsel the
opportunity to review all responses to requests for additional information and
replies to comments prior to their being filed with, or sent to, the SEC.
Whenever any event occurs which is required to be set forth in an amendment or
supplement to the Proxy Statement, the Company shall promptly inform Parent of
such occurrence and file with the SEC or its staff and/or mail to stockholders
of the Company, such amendment or supplement.

   The Proxy Statement shall include the unanimous recommendation of the Board
in favor of adoption and approval of this Agreement and approval of the Merger
(subject to the terms of Section 5.4(c) hereof).

   (b) Solely for the purposes of this Agreement, the parties hereby
acknowledge and agree that the recommendation of the Board shall be deemed to
continue to be "unanimous" despite an abstention by one or more directors of
the Board or any committee thereof subsequent to the date of this Agreement on
a vote by the members of the Board or a committee thereof with respect to any
matter pertaining to the recommendation subsequent to the initial unanimous
Board approval, and the Board or any committee thereof

                                      A-25

shall not have been deemed to have withdrawn, withheld, amended, changed or
modified in a manner adverse to Parent, nor shall it have been deemed to have
failed to include in the Proxy Statement the unanimous recommendation of the
Board that holders of Shares vote in favor of, adopt and approve this
Agreement and approve the Merger, by virtue of such abstention; provided,
however, that the foregoing shall only apply if, and only if, the following
conditions and terms (collectively, the "Abstention Terms") are met: (i) such
an abstention does not affect the due and valid recommendation of the Board
with respect to the Merger under the Company Charter Documents and all
applicable Legal Requirements; (ii) no abstaining Board member (or any
affiliate thereof, including, without limitation, the Company or any of its
subsidiaries) makes any public statement with respect to the abstention,
either explicitly or implicitly, in a manner adverse to Parent nor any public
statement reasonably likely to have an adverse effect on the adoption and
approval of this Agreement and the approval of the Merger at the Stockholders'
Meeting (defined in Section 5.2(a) below); and (iii) except pursuant to and in
accordance with this Section 5.1(b), no abstention in any way or fashion
affects Parent's rights and the Company's obligations with respect to the
maintenance, and the manner of maintenance, of the Board's unanimous
recommendation hereunder.

   5.2 Meeting of Company Stockholders.

   (a) Promptly after the date hereof, the Company shall take all action
necessary in accordance with Delaware Law and the Company Charter Documents to
convene an annual or special meeting of its stockholders for the purpose of
considering and taking action on this Agreement and the Merger (the
"Stockholders' Meeting"), to be held as promptly as practicable, and in any
event (to the extent permissible under applicable law) within thirty (30)
calendar days after the Proxy Statement is cleared by the SEC. Subject to the
terms of Section 5.4(c) hereof, the Company shall use its commercially
reasonable efforts to solicit from its stockholders proxies in favor of the
adoption and approval of this Agreement and the approval of the Merger and
shall take all other action necessary or advisable to secure the vote or
consent of its stockholders required by the rules of Nasdaq or Delaware Law to
obtain such approvals. Notwithstanding anything to the contrary contained in
this Agreement, the Company may adjourn or postpone the Stockholders' Meeting
to the extent necessary to ensure that any necessary supplement or amendment
to the Proxy Statement is provided to the Company's stockholders in advance of
a vote on the Merger and this Agreement or, if as of the time for which the
Stockholders' Meeting is originally scheduled (as set forth in the Proxy
Statement) there are insufficient shares of Company Common Stock represented
(either in person or by proxy) to constitute a quorum necessary to conduct the
business of the Stockholders' Meeting. The Company shall ensure that the
Stockholders' Meeting is called, noticed, convened, held and conducted, and
that all proxies solicited by the Company in connection with the Stockholders'
Meeting are solicited, in compliance with Delaware Law, the Company Charter
Documents, the rules of Nasdaq and all other applicable legal requirements.
The Company's obligation to call, give notice of, convene and hold the
Stockholders' Meeting in accordance with this Section 5.2 shall not be limited
to or otherwise affected by the commencement, disclosure, announcement or
submission to the Company of any Acquisition Proposal (it being agreed and
understood however, that if this Agreement shall terminate in accordance with
Section 7.1, such obligation to call, give notice of, convene and hold the
Stockholders' Meeting shall terminate).

   (b) Subject to the terms of Section 5.4(c) hereof: (i) the Board shall
recommend that the Company's stockholders vote in favor of and adopt and
approve this Agreement and approve the Merger at the Stockholders' Meeting;
(ii) the Proxy Statement shall include (x) the fairness opinion referred to in
Section 2.21 hereof and (y) a statement to the effect that the Board has
unanimously recommended that the Company's stockholders vote in favor of and
adopt and approve this Agreement and approve the Merger at the Stockholders'
Meeting; and (iii) neither the Board nor any committee thereof shall withdraw,
amend, change or modify, or propose or resolve to withdraw, amend, change or
modify in a manner adverse to Parent, the unanimous recommendation of the
Board that the Company's stockholders vote in favor of and adopt and approve
this Agreement and approve the Merger. For purposes of this Agreement, said
recommendation of the Board of Directors shall be deemed to have been modified
in a manner adverse to Parent if such recommendation shall no longer be
unanimous.


                                      A-26

   5.3 Confidentiality; Access to Information.

   (a) The parties acknowledge that Parent and the Company have previously
executed a Confidentiality Agreement, dated as of October 4, 2002, as amended
on February 20, 2003 (as amended, the "Confidentiality Agreement"), which
Confidentiality Agreement will continue in full force and effect in accordance
with its terms.

   (b) The Company shall afford Parent and its accountants, counsel, advisors
and other representatives reasonable access during normal business hours, upon
reasonable notice, to the properties, books, records and personnel of the
Company during the period prior to the Effective Time to obtain all
information concerning the businesses, including the status of product
development efforts, properties, financial positions, results of operations
and personnel of the Company, as Parent may reasonably request.

   (c) No information or knowledge obtained by Parent in any investigation
pursuant to this Section 5.3 will affect or be deemed to modify any
representation or warranty contained herein or the conditions to the
obligations of the parties to consummate the Transactions.

   5.4 No Solicitation.

   (a) Except to the extent permitted by the terms of this Section 5.4, from
the date hereof until the earlier of the approval and adoption of this
Agreement and approval of the Merger by the Company's stockholders or the
termination of this Agreement, the Company and its subsidiaries shall not, nor
will they authorize or permit any of their respective officers, directors,
affiliates or employees or any investment banker, attorney, accountant, or
other advisor or representative retained by any of them ("Representatives")
to, directly or indirectly: (i) solicit, initiate, knowingly or intentionally
encourage, facilitate or induce the making, submission or announcement of any
Acquisition Proposal (as defined in Section 5.4(d) hereof); (ii) participate
in any negotiations or discussions regarding, or furnish to any person any
non-public information with respect to, or take any other action to facilitate
any inquiries or the making of any proposal that constitutes or may reasonably
be expected to lead to, any Acquisition Proposal; (iii) subject to the terms
of Section 5.4(c) hereof, approve, endorse or recommend any Acquisition
Proposal; or (iv) enter into any letter of intent or similar document or any
Contract contemplating or otherwise relating to any Acquisition Transaction
(as defined in Section 5.4(d) hereof); provided, however, that the terms of
this Section 5.4 shall not prohibit the Company from furnishing nonpublic
information regarding the Company and its subsidiaries to, entering into a
confidentiality agreement with or entering into negotiations or discussions
with, any person or group in response to an Acquisition Proposal submitted by
such person or group (and not withdrawn) if: (1) neither the Company nor its
subsidiaries nor any of their respective Representatives shall have violated
any of the restrictions set forth in this Section 5.4 in connection with such
Acquisition Proposal; (2) the Board concludes in good faith, after
consultation with its outside legal counsel, that such action is required in
order for the Board to comply with its fiduciary duties to the Company's
stockholders under applicable law; (3) (x) at least two (2) business days
prior to furnishing any such nonpublic information to, or entering into
negotiations or discussions with, such person or group, the Company gives
Parent written notice of the identity of such person or group and of the
Company's intention to furnish nonpublic information to, or enter into
negotiations or discussions with, such person or group, and (y) the Company
receives from such person or group an executed confidentiality agreement
containing limitations on the use and disclosure of all nonpublic written and
oral information furnished to such person or group by or on behalf of the
Company which are no less favorable to the Company than the Confidentiality
Agreement; and (4) contemporaneously with furnishing any such nonpublic
information to such person or group, the Company furnishes such nonpublic
information to Parent (to the extent such nonpublic information has not been
previously furnished by the Company to Parent). In addition to the foregoing,
the Company shall (i) provide Parent with at least forty-eight (48) hours
prior written notice (or such lesser prior notice as provided to the members
of the Board, but in no event less than eight hours) of a meeting of the Board
at which the Board is reasonably expected to consider a Superior Offer and
(ii) provide Parent with at least two (2) business days prior written notice
of a meeting of the Board at which the Board is reasonably expected to
recommend a Superior Offer to its stockholders and together with such notice a
copy of any definitive documentation relating to such Superior Offer and such
other documentation reflecting the terms of the Superior Offer as being
considered by the Board. The terms of this Section 5.4 shall not prohibit the
Company from taking any action necessary in

                                      A-27

order to comply with Rule 14d-9 or Rule 14e-2 promulgated under the Exchange
Act, provided that neither the Company nor its Board shall, except as
permitted by Section 5.4(c), propose to withdraw, amend, change or modify its
unanimous recommendation of this Agreement and the Merger, or to approve or
recommend, or propose to publicly approve or recommend, an Acquisition
Proposal. The Company and its subsidiaries shall immediately cease any and all
existing activities, negotiations or discussions with any parties conducted
heretofore with respect to any Acquisition Proposal. Without limiting the
foregoing, it is understood that any violation of the restrictions set forth
in the preceding two sentences by any officer or director of the Company or
any of its subsidiaries or any Representative of the Company or any of its
subsidiaries shall be deemed to be a breach of this Section 5.4 by the
Company.

   (b) In addition to the obligations of the Company set forth in Section 5.4
hereof, the Company as promptly as practicable shall advise Parent orally
(within one business day) and in writing (within two business days) of any
request received by the Company for nonpublic information which the Company
reasonably believes would lead to an Acquisition Proposal or of any
Acquisition Proposal, or any inquiry received by the Company with respect to
or which the Company reasonably believes would lead to any Acquisition
Proposal, the material terms and conditions of such request, Acquisition
Proposal or inquiry, and the identity of the person or group making any such
request, Acquisition Proposal or inquiry. The Company shall keep Parent
informed in all material respects of the status and details (including
material amendments or proposed amendments) of any such request, Acquisition
Proposal or inquiry.

   (c) Nothing in this Agreement shall prevent the Board from withdrawing,
amending, changing or modifying its unanimous recommendation in favor of the
Transactions at any time prior to the approval and adoption of this Agreement
and approval of the Merger by the Company's stockholders, but the Board may do
so only to terminate this Agreement in accordance with Section 7.1(e) hereof
and only if (i) a Superior Offer (as defined in Section 5.4(d) hereof) is made
to the Company and is not withdrawn, and, concurrent with the termination of
this Agreement pursuant to Section 7.1(e) hereof, the Board shall cause the
Company to enter into a definitive agreement with respect to such Superior
Proposal, (ii) neither the Company nor any of its subsidiaries nor any of
their respective Representatives shall have violated any of the restrictions
set forth in Section 5.4 hereof in connection with such Superior Offer, and
(iii) the Board concludes in good faith, after consultation with its outside
counsel, that in light of such Superior Offer the withdrawal, amendment,
change or modification of such recommendation is required in order for the
Board to comply with its fiduciary duties to the Company's stockholders under
applicable law.

   (d) For purposes of this Agreement, (i) "Acquisition Proposal" shall mean
any offer or proposal (other than an offer or proposal by Parent or Merger
Sub) relating to any Acquisition Transaction. For the purposes of this
Agreement, (ii) "Acquisition Transaction" shall mean any transaction or series
of related transactions other than the Transactions involving: (A) any
acquisition or purchase from the Company by any person or "group" (as defined
under Section 13(d) of the Exchange Act and the rules and regulations
thereunder) of more than a fifteen percent (15%) interest in the total
outstanding voting securities of the Company or any of its subsidiaries or any
tender offer or exchange offer that if consummated would result in any person
or "group" (as defined under Section 13(d) of the Exchange Act and the rules
and regulations thereunder) beneficially owning fifteen percent (15%) or more
of the total outstanding voting securities of the Company or any of its
subsidiaries or any merger, consolidation, business combination or similar
transaction involving the Company (excluding the ISAC Sale) pursuant to which
the stockholders of the Company immediately preceding such transaction hold
less than eighty five percent (85%) of the equity interests in the surviving
or resulting entity of such transaction; (B) any sale, lease, exchange,
transfer, license (other than in the ordinary course of business and
consistent with past practice), acquisition or disposition of more than
fifteen percent (15%) of the assets of the Company; or (C) any liquidation or
dissolution of the Company, and (iii) "Superior Offer" shall mean an
unsolicited, bona fide written offer made by a third party to consummate any
Acquisition Proposal on terms that the Board determines, in its reasonable
judgment (after consultation with a reputable financial advisor) to be more
favorable to the Company stockholders from a financial point of view than the
terms of the Transactions; provided, however, that any such offer shall not be
deemed to be a "Superior Offer" if any financing required to consummate the
transaction contemplated by such offer is not committed and is not likely in
the reasonable judgment of the Board to be obtained by such third party on a
timely basis.

the parties agrees to use all commercially reasonable efforts to take, or
cause to be taken, all actions, and to do, or cause to be done, and to assist
and cooperate with the other parties in doing, all things necessary, proper or
advisable to consummate and make effective, in the most expeditious manner
practicable, the Transactions, including using reasonable efforts to
accomplish the following: (i) the taking of all reasonable acts necessary to
cause the conditions precedent set forth in ARTICLE VI to be satisfied, (ii)
the obtaining of all necessary actions or nonactions, waivers, consents,
approvals, orders and authorizations from Governmental Entities and the making
of all necessary registrations, declarations and filings (including
registrations, declarations and filings with Governmental Entities, if any)
and the taking of all reasonable steps as may be necessary to avoid any suit,
claim, action, investigation or proceeding by any Governmental Entity, (iii)
the obtaining of all consents, approvals or waivers from third parties
required as a result of the transactions contemplated in this Agreement, (iv)
the defending of any suits, claims, actions, investigations or proceedings,
whether judicial or administrative, challenging this Agreement or the
consummation of the transactions contemplated hereby, including seeking to
have any stay or temporary restraining order entered by any court or other
Governmental Entity vacated or reversed and (v) the execution or delivery of
any additional instruments reasonably necessary to consummate the
Transactions, and to fully carry out the purposes of, this Agreement. In
connection with and without limiting the foregoing, the Company and its Board
shall, if any state takeover statute or similar statute or regulation is or
becomes applicable to the Transactions or this Agreement, use all commercially
reasonable efforts to ensure that the Transactions may be consummated as
promptly as practicable on the terms contemplated by this Agreement and
otherwise to minimize the effect of such statute or regulation on the
Transactions and this Agreement. Notwithstanding anything herein to the
contrary, nothing in this Agreement shall be deemed to require Parent or any
subsidiary or affiliate of Parent to agree to any divestiture by itself or the
Company or any of their respective affiliates of shares of capital stock or of
any business, assets or property, or the imposition of any material limitation
on the ability of any of them to conduct their businesses or to own or
exercise control of such assets, properties and stock.

   (b) The Company shall give prompt notice to Parent upon becoming aware that
any representation or warranty made by it contained in this Agreement has
become untrue or inaccurate in any material respect, or of any failure of the
Company to comply with or satisfy in any material respect any covenant,
condition or agreement to be complied with or satisfied by it under this
Agreement, in each case, such that the conditions set forth in ARTICLE VI
hereof would not be satisfied; provided, however, that no such notification
shall affect the representations, warranties, covenants or agreements of the
parties or the conditions to the obligations of the parties under this
Agreement.

   5.7 Third Party Consents. As soon as practicable following the date hereof,
Company shall use its commercially reasonable efforts to obtain any consents,
waivers and approvals under any of its or its subsidiaries' respective
Contracts required to be obtained in connection with the consummation of the
Transactions, including those set forth on Section 5.7 of the Company
Schedule.


                                      A-29

   5.8 Directors' and Officers' Indemnification.

   (a) From and after the Effective Time, Parent shall, and shall cause the
Surviving Corporation to fulfill and honor in all respects the obligations of
the Company pursuant to any indemnification provisions of Company's directors
and officers under the Company Charter Documents as in effect on the date
hereof (the "Indemnified Parties"). The Certificate of Incorporation and
Bylaws of the Surviving Corporation will contain provisions with respect to
exculpation and indemnification that are at least as favorable to the
Indemnified Parties as those contained in the Company Charter Documents as in
effect on the date hereof which provisions will not be amended, repealed or
otherwise modified for a period of six (6) years from the Effective Time in
any manner that would adversely affect the rights thereunder of individuals
who, immediately prior to the Effective Time, were directors, officers,
employees or agents of the Company, unless such modification is required by
applicable law.

   (b) The Company shall purchase, for a price (which shall in no event exceed
the Cap Amount regardless of any amounts credited against premium payments
previously paid by the Company) not to exceed the amount set forth on
Section 5.8(b) of the Company Schedule (the "Cap Amount"), directors' and
officers' liability tail coverage (for a period of six (6) years following the
Effective Time), covering those persons who are currently covered by the
Company's directors' and officers' liability insurance policy, on terms
comparable to those applicable to the current directors and officers of the
Company, and covering all periods prior to the Effective Time (the "Tail
Coverage").

   (c) This Section 5.8 is intended for the irrevocable benefit of, and to
grant third party rights to, the Indemnified Parties and shall be binding on
all successors and assigns of Parent, the Company and the Surviving
Corporation. Each of the Indemnified Parties shall be entitled to enforce the
covenants contained in this Section 5.8.

   5.9 Regulatory Filings; Reasonable Efforts. As soon as may be reasonably
practicable, the Company and Parent each shall file any appropriate pre-merger
notifications under the competition laws or regulations of any jurisdiction,
as reasonably agreed by the parties to apply. The Company and Parent each
shall promptly (a) supply the other with any information which may be required
in order to effectuate such filings and (b) supply any additional information,
which reasonably may be required by the competition or merger control
authorities of any other jurisdiction and which the parties may reasonably
deem appropriate; provided, however, that Parent shall not be required to
agree to any divestiture by Parent or the Company or any of Parent's
subsidiaries or affiliates of shares of capital stock or of any business,
assets or property of Parent or its subsidiaries or affiliates or of the
Company, its affiliates, or the imposition of any material limitation on the
ability of any of them to conduct their businesses or to own or exercise
control of such assets, properties and stock.

   5.10 Company Actions with Respect to Employees.

   (a) Company shall use its commercially reasonable efforts (which, for
clarification, shall not obligate the Company to incur any additional
expenditures with the exception of individual bonuses to be mutually
determined by the parties and expenditures made in the ordinary course of the
Company's business in connection with the retention of its employees), to
cause each of its current employees set forth in Section 5.10 of the Company
Schedule (collectively, the "Key Retention Employees") to remain employed with
Company or become employed with Parent (as Parent shall designate) upon the
consummation of the Merger, the parties acknowledging and agreeing that the
list of such individuals in such Section 5.10 of the Company Schedule may be
amended, from time to time prior to the Effective Time, pursuant to mutual
agreement by the parties. In addition, the Company shall notify the Key
Retention Employees under the heading "Interim Employees" under such
Section 5.10 (the "Interim Employees") that they will only be employed by
Company or Parent, as the case may be, to facilitate the integration of the
combined company after the Closing, and for only that period of time after the
Closing as Parent deems, in its sole discretion, necessary for such purpose,
and will be terminated immediately upon the expiration of such period.

   (b) In connection with Parent's efforts to retain the Key Retention
Employees prior to the Closing, Parent agrees to use commercially reasonable
efforts to extend substantially concurrent notification to each

                                      A-30

such employee his or her terms and status of employment with Parent, and other
similar employment-related information which is customarily shared with
prospective employees.

   (c) At any time prior to the Effective Time (it being acknowledged and
agreed that Company shall in its sole discretion determine such time or times
prior to the Effective Time as it deems appropriate), Company shall take all
necessary action to effect the termination of all Company's employees who are
not Key Retention Employees (collectively, the "Non-Retention Employees"),
effective on or prior to the Effective Time; provided, that the Company may
delay taking such actions with respect to certain Non-Retention Employees if
in its sole discretion the Company determines that terminating such Non-
Retention Employees prior to the Effective Time would have an adverse effect
on the Company in the event that this Agreement is terminated.

   5.11 Termination of Certain Benefit Plans. Effective no later than the day
immediately preceding the Effective Time, the Company and its Affiliates, as
applicable, shall each terminate any and all group severance, separation or
salary continuation plans, programs or arrangements (excluding, in each case,
the agreements listed on Section 5.11 of the Company Schedule) and any and all
plans intended to include a Code Section 401(k) arrangement (unless Parent
provides written notice to the Company that such 401(k) plans shall not be
terminated) (collectively, for purposes of this Section 5.11 "Company Employee
Plans"). Unless Parent provides such written notice to the Company, no later
than five business days prior to the Effective Time, the Company shall provide
Parent with evidence that such Company Employee Plan(s) have been terminated
(effective no later than the day immediately preceding the Effective Time)
pursuant to resolutions of the Board. The form and substance of such
resolutions shall be subject to review and approval of Parent. The Company
also shall take such other actions in furtherance of terminating such Company
Employee Plan(s) as Parent may reasonably require.

   5.12 Employee Benefits. As soon as practicable after the Effective Time,
Parent shall provide the employees of the Company and its subsidiaries who
remain employed after the Effective Time (each, a "Transferred Company
Employee" and collectively, the "Transferred Company Employees") with
substantially the same types and levels of compensation and employee benefits
as provided to such Transferred Company Employees by the Company immediately
prior to the Merger ("Substantially Matching Employment Terms"), provided,
however, that a reduction in salary of up to five percent (5%) for Transferred
Company Employees who are billable employees of the Company and up ten percent
(10%) for Transferred Company Employees for non-billable employees of the
Company shall be deemed to be provided Substantially Matching Employment Terms
so long as such Transferred Company Employees are allowed to recoup the
applicable reduced amount pursuant to Parent's current bonus program. Further,
Parent shall treat and cause its applicable benefit plans (with the exception
of Parent's sabbatical program) to treat the service of Transferred Company
Employees with the Company or any subsidiary of the Company prior to the
Effective Time as service rendered to Parent or any affiliate of Parent for
purposes of eligibility to participate and vesting, including applicability of
minimum waiting periods for participation, but not for benefit accrual. Parent
shall use commercially reasonable efforts to provide that no Transferred
Company Employee, or any of his or her eligible dependents, who, at the
Effective Time, are participating in the Company group health plan shall be
excluded from the Parent's group plan, or limited in coverage thereunder, by
reason of any waiting period restriction or pre-existing condition limitation;
provided that such Transferred Employees are based in the United States and
meet applicable actively at work requirements as of the Effective Time.
Notwithstanding the foregoing, and except for its obligation to provide
Substantial Matching Employment Terms to each Transferred Company Employee as
set forth in this Section 5.12, Parent shall not be required to provide any
coverage, benefits, or credit beyond that already promised in accordance with
this Section 5.12 to any Transferred Company Employee which would be
inconsistent with the terms of Parent benefit plans.

   5.13 FIRPTA Certificate. On or prior to the Effective Time, the Company
shall deliver to Parent a properly executed statement in a form reasonably
acceptable to Parent for purposes of satisfying Parent's obligations under
Treasury Regulation Section 1.1445-2(c)(3).

Parent and the Company;

   (b) by either the Company or Parent if the Effective Time shall not have

constitutes a breach of this Agreement;

   (d) by either the Company or Parent if the required approval of the
stockholders of the Company contemplated by this Agreement shall not have been

Stockholders' Meeting or at any adjournment thereof; provided, however, that
the right to terminate this Agreement under this Section 7.1(d) shall not be
available to the Company where the failure to obtain the Company stockholder
approval shall have been caused by the action or failure to act of the Company
and such action or failure to act constitutes a breach by the Company of this
Agreement;

such that the conditions set forth in Section 6.2(a) or Section 6.2(b) hereof
would not be satisfied as of the time of such breach or as of the time such
representation or warranty shall have become untrue, provided, however, that
if such inaccuracy in Parent's representations and warranties or breach by
Parent is curable by Parent through the exercise of its commercially
reasonable efforts, then the Company may not terminate this Agreement under
this Section 7.1(f) for thirty (30) calendar days after delivery of written
notice from the Company to Parent of such breach, provided Parent continues to

breach by Parent is cured during such thirty (30) calendar day period);

   (g) by Parent, upon a breach of any representation, warranty, covenant or
agreement on the part of the Company set forth in this Agreement, or if any

in Section 2.19(c) (Suppliers and Customers) of the Agreement regarding the
Material Customers' relationships with the Company shall not be considered a
breach of such representation and warranty as long as the condition set forth
in Section 6.3(g) hereof remains satisfied.

   (h) by Parent, upon a material breach of the provisions of Section 5.4
hereof;

   (i) by Parent if a Triggering Event (as defined below) shall have occurred.

   termination, the Company has received, or a third party has announced, an
   Acquisition Proposal and (y) such breach is intended to or has the effect of
   facilitating such Acquisition Proposal or benefiting the person making such
   acquisition proposal without similarly benefiting Parent, an amount equal to
   the out-of-pocket fees and expenses incurred by Parent and Merger Sub in
   connection with the negotiation, execution and delivery of this Agreement
   and the transactions contemplated hereby (including, without limitation,
   reasonable attorney fees and expenses, reasonable advisor fees and expenses,
   and travel costs) (the "Expenses"); provided, that the Company shall not be
   required, pursuant to this Section 7.3(b)(iv), to pay Parent for Expenses in
   excess of $500,000 in the aggregate. Notwithstanding the foregoing, payment
   of such Expenses shall not constitute liquidated damages with respect to any
   claim which Parent or Merger Sub would be entitled to assert against the
   Company or its assets, or against any of the Company's directors, officers,
   employees or stockholders, with respect to any such breach, and shall not
   constitute the sole and exclusive remedy with respect to any such breach.

      (vi) The Company hereby acknowledges and agrees that the agreements set
   forth in this Section 7.3(b) 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 to
   pay in a timely manner the amounts due pursuant to this Section 7.3(b) and,
   in order to obtain such payment, Parent makes a claim that results in a
   judgment against the Company for the amounts set forth in this
   Section 7.3(b), the Company shall pay to Parent its reasonable costs and
   expenses (including reasonable attorneys' fees and expenses) in connection
   with such suit, together with interest on the amounts set forth in this
   Section 7.3(b) at the prime rate of The Chase Manhattan Bank in effect on
   the date such payment was required to be made; provided, however, that if
   Parent makes a claim for the amounts set forth in this Section 7.3(b) that
   results in a judgment against Parent, Parent shall pay to the Company its
   reasonable costs and expenses (including reasonable attorneys' fees and
   expenses) in connection with such suit. Payment of the fees described in
   this Section 7.3(b) shall not be in lieu of damages incurred in the event of
   any intentional or willful breach of, or any intentional misrepresentation
   made in, this Agreement.

      (vii) Notwithstanding anything to the contrary set forth in this
   Agreement, each of the parties hereto hereby expressly acknowledges and
   hereby agrees that, with respect to any termination of this Agreement
   pursuant to Section 7.1 hereof (other than a termination based upon the
   willful or intentional breach of, or any intentional misrepresentation made
   in, this Agreement) under circumstances in which the Termination Fee is
   payable pursuant to this Section 7.3(b), payment of the Termination Fee
   shall constitute liquidated damages with respect to any claim for damages or
   any other claim which Parent or

                                      A-36

   Merger Sub would otherwise be entitled to assert against the Company or its
   assets, or against any of the Company's directors, officers, employees or
   stockholders, with respect to any such termination of this Agreement, and
   shall constitute the sole and exclusive remedy with respect to any such
   termination of this Agreement. The parties hereto expressly acknowledge and
   agree that, in light of the difficulty of accurately determining actual
   damages with respect to the foregoing upon any such termination of this
   Agreement pursuant to Section 7.1 hereof (other than a termination based
   upon the willful or intentional breach of, or any intentional
   misrepresentation made in, this Agreement) under circumstances in which the
   Termination Fee is payable pursuant to this Section 7.3(b), the right to
   such payment: (A) constitutes a reasonable estimate of the damages that will
   be suffered by reason of any such termination this Agreement and (B) shall
   be in full and complete satisfaction of any and all damages arising as a
   result of any such termination of this Agreement. Except for nonpayment of
   the Termination Fee pursuant to this Section 7.3(b) the parties hereto
   hereby agree that, upon any termination of this Agreement pursuant to
   Section 7.1 hereof (other than a termination based upon the willful or
   intentional breach of, or any intentional misrepresentation made in, this
   Agreement) under circumstances in which the Termination Fee is payable
   pursuant to this Section 7.3(b), in no event shall Parent or Merger Sub be
   entitled to seek or to obtain any recovery or judgment against the Company
   or any subsidiaries of the Company or any of their respective assets, or
   against any of their respective directors, officers, employees or
   stockholders for any such termination of this Agreement, and in no event
   shall Parent or Merger Sub be entitled to seek or obtain any other damages
   of any kind, including, without limitation, consequential, special, indirect
   or punitive damages, for any such termination of this Agreement.
   Notwithstanding the foregoing, payment of the Termination Fee pursuant to
   this Section 7.3(b) shall not constitute liquidated damages with respect to
   any claim for damages or any other claim which Parent or Merger Sub would be
   entitled to assert against the Company or its assets, or against any of the
   Company's directors, officers, employees or stockholders, with respect to
   any such termination of this Agreement based upon the willful or intentional
   breach or intentional misrepresentation of any representations, warranties
   or covenants of the Company in this Agreement, and shall not constitute the
   sole and exclusive remedy with respect to any such termination of this
   Agreement based upon the willful or intentional breach or misrepresentation
   of any of the representations, warranties or covenants of the Company in
   this Agreement.

      (viii) For the purposes of this Agreement, "Company Acquisition" shall
   mean any of the following transactions (other than the transactions
   contemplated by this Agreement): (i) a merger, consolidation, business
   combination, recapitalization, liquidation, dissolution or similar
   transaction involving the Company pursuant to which the stockholders of the
   Company immediately preceding such transaction hold less than a majority of
   the aggregate equity interests in the surviving or resulting entity of such
   transaction, (ii) a sale or other disposition by the Company of assets
   representing in excess of a majority of the aggregate fair market value of
   the Company's businesses immediately prior to such sale or (iii) the
   acquisition by any person or group (including by way of a tender offer or an
   exchange offer or issuance by the Company), directly or indirectly, of
   beneficial ownership or a right to acquire beneficial ownership of shares
   representing in excess of a majority of the voting power of the then
   outstanding shares of capital stock of the Company.

   7.4 Amendment. Subject to applicable law, this Agreement may be amended by
the parties hereto at any time by execution of an instrument in writing signed
on behalf of each of Parent and the Company.

   7.5 Extension; Waiver. At any time prior to the Effective Time, any party
hereto may, to the extent legally allowed, (i) extend the time for the
performance of any of the obligations or other acts of the other parties
hereto, (ii) waive any inaccuracies in the representations and warranties made
to such party contained herein or in any document delivered pursuant hereto
and (iii) waive compliance with any of the agreements or conditions for the
benefit of such party contained herein. Any agreement on the part of a party
hereto to any such extension or waiver shall be valid only if set forth in an
instrument in writing signed on behalf of such party. Delay in exercising any
right under this Agreement shall not constitute a waiver of such right.

   (a) When a reference is made in this Agreement to Exhibits, such reference
shall be to an Exhibit to this Agreement unless otherwise indicated. When a
reference is made in this Agreement to Sections, such reference shall be to a
Section of this Agreement unless otherwise indicated. Unless otherwise
indicated the words "include," "includes" and "including" when used herein
shall be deemed in each case to be followed by the words "without limitation."
The table of contents and headings contained in this Agreement are for
reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.

subsidiaries of such entity. Reference to the subsidiaries of an entity shall
be deemed to include all direct and indirect subsidiaries of such entity.

   (b) For purposes of this Agreement, the term "knowledge" means with respect
to a party hereto, with respect to any matter in question, that any of the
executive officers or directors of such party has actual knowledge of such
matter; provided that with respect to any executive officer, such executive
officer shall have made reasonable due and diligent inquiry of the employees
responsible for such matter in question; and provided, further, that if any
executive officer does not make such reasonable due and diligent inquiry, then
such executive officer shall be deemed to have actual knowledge of those facts
or matters that such executive officer would have had, had he or she made such
inquiry.

   (c) For purposes of this Agreement, the term "Material Adverse Effect" when
used in connection with any entity means any change, event, violation,

entity and its subsidiaries taken as a whole, or the ability of such entity to
perform its obligations under this Agreement and timely consummate the
Transactions; provided, however, none of the following shall be deemed in
themselves, either alone or in combination, to constitute, and none of the
following shall be taken into account in determining whether there has been or
will be, a Material Adverse Effect on the Company: (i) any change in the
market price or trading volume of the Shares; (ii) any failure, excluding the
cause of any failure, by the Company to meet internal projections or forecasts
or published revenue or earnings predictions for any period ending (or for
which revenues or earnings are released) on or after the date of this
Agreement; (iii) any adverse change, event, violation, inaccuracy,
circumstance or effect that the Company successfully bears the burden of
proving results from or is attributable to conditions affecting the industries
in which the Company participates, the United States economy as a whole, or
foreign economies in any locations where the Company or any of its
subsidiaries has material operations or sales (which changes in each case do
not disproportionately affect the Company or its subsidiaries, as the case may
be); (iv) any adverse change, event, violation, inaccuracy, circumstance or
effect resulting from Company's compliance with the terms of, or the taking of
any action required by, this Agreement; (v) the termination, cancellation,
deferral or other adverse modification of any Contracts by any customers; or
(vi) any voluntary termination of the employment of employees of the Company
by such employees. Notwithstanding the exclusionary provisos (v) and (vi)
immediately in the foregoing and with respect to the definition of "Material
Adverse Effect," such provisos shall in no way or fashion limit or otherwise
affect, Parent's rights with respect to the conditions set forth in
Sections 6.3(f) or 6.3(g) hereof.

counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each
of the parties and delivered to the other party, it being understood that all
parties need not sign the same counterpart.

   9.5 Entire Agreement; Third Party Beneficiaries. This Agreement and the
documents and instruments and other agreements among the parties hereto as
contemplated by or referred to herein, including the Company Schedule, (a)
constitute the entire agreement among the parties with respect to the subject
matter hereof and supersede all prior agreements and understandings, both
written and oral, among the parties with respect to the subject matter hereof,

force and effect and shall survive any termination of this Agreement; and (b)
are not intended to confer upon any other person any rights or remedies
hereunder, except as specifically provided in Section 5.8 hereof.

   9.6 Severability. In the event that any provision of this Agreement, or the
application thereof, becomes or is declared by a court of competent
jurisdiction to be illegal, void or unenforceable, the remainder of this
Agreement will continue in full force and effect and the application of such
provision to other persons or

                                      A-39

circumstances will be interpreted so as reasonably to effect the intent of the
parties hereto. The parties further agree to replace such void or
unenforceable provision of this Agreement with a valid and enforceable
provision that will achieve, to the extent possible, the economic, business
and other purposes of such void or unenforceable provision.

   9.7 Other Remedies; Specific Performance. Except as otherwise provided
herein, any and all remedies herein expressly conferred upon a party will be
deemed cumulative with and not exclusive of any other remedy conferred hereby,
or by law or equity upon such party, and the exercise by a party of any one
remedy will not preclude the exercise of any other remedy. The parties hereto
agree that irreparable damage would occur in the event that any of the
provisions of this Agreement were not performed in accordance with their
specific terms or were otherwise breached. It is accordingly agreed that the
parties shall be entitled to seek an injunction or injunctions to prevent
breaches of this Agreement and to enforce specifically the terms and
provisions hereof in any court of the United States or any state having
jurisdiction, this being in addition to any other remedy to which they are
entitled at law or in equity.

   9.8 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware, regardless of the laws that
might otherwise govern under applicable principles of conflicts of law
thereof.

   9.9 Rules of Construction. The parties hereto agree that they have been
represented by counsel during the negotiation and execution of this Agreement
and, therefore, waive the application of any law, regulation, holding or rule
of construction providing that ambiguities in an agreement or other document
will be construed against the party drafting such agreement or document.

   9.10 Assignment. No party may assign either this Agreement or any of its
rights, interests, or obligations hereunder without the prior written approval
of the other parties. Subject to the preceding sentence, this Agreement shall
be binding upon and shall inure to the benefit of the parties hereto and their
respective successors and permitted assigns.

   9.11 Waiver of Jury Trial. EACH OF PARENT, COMPANY AND MERGER SUB HEREBY
IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR
COUNTERCLAIM (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR
RELATING TO THIS AGREEMENT OR THE ACTIONS OF PARENT, COMPANY OR MERGER SUB IN
THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT HEREOF.

    Appraisal Rights -- Section 262 of the Delaware General Corporation Law


   (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 ss. 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 ss. 251 (other than a merger effected pursuant to ss.
251(g) of this title), ss. 252, ss. 254, ss. 257, ss. 258, ss. 263 or ss. 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 ss. 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 ss.ss. 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.

          (3)  In the event all of the stock of a subsidiary Delaware
               corporation party to a merger effected under ss. 253 of this
               title is not owned by the parent corporation immediately prior
               to the

                                      B-1

               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 ss. 228
               or ss. 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

                                      B-2

               be not more than 10 days prior to the date the notice is given,
               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
participate fully in all proceedings until it is finally determined that such
stockholder is not entitled to appraisal rights under this section.


                                      B-3

   (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.

                                                                        ANNEX C

                            Fairness Opinion Letter


April 8, 2003


CONFIDENTIAL

Board of Directors
Predictive Systems, Inc.
19 West 44th Street
9th Floor
New York NY 10036

Dear Members of the Board:

   We understand that Predictive Systems, Inc., a Delaware corporation (the
"Company"), International Network Services, Inc., a Delaware corporation
("Parent"), and Mid-West Acquisition Corporation, a Delaware corporation and a
wholly owned subsidiary of Parent ("Merger Sub") have entered into an
Agreement and Plan of Merger (the "Agreement") pursuant to which Merger Sub
shall be merged with and into the Company (the "Merger"), the separate
corporate existence of Merger Sub shall cease and the Company shall continue
as the surviving corporation (the "Transaction").

   The merger consideration per share of common stock of the Company (the
"Merger Consideration") at closing ("Closing") shall equal a cash amount equal
to the quotient obtained by dividing (x) the Total Consideration of
$19.187 million minus any Adjustment Amount (if the Adjustment Amount shall
have been calculated pursuant to (a) below) or plus any Adjustment Amount (if
the Adjustment Amount shall have been calculated pursuant to (b) below), by
(y) the Total Outstanding Shares. Total Outstanding Shares equal the total
number of shares of common stock, par value $.001 per share ("Share"), of the
Company issued and outstanding immediately prior to the Effective Time (as
defined in the Agreement). The Adjustment Amount shall be zero if Final Net
Assets is within +/- $1.25 million of the Estimated Net Assets, otherwise the
Adjustment Amount shall equal either:

   (a) if the Final Net Assets are less than $14.137 million (represents
Estimated Net Assets minus $1.25 million), the amount by which such amount
exceeds the Final Net Assets, or

   (b) if the Final Net Assets are greater than $16.637 million (represents
Estimated Net Assets plus $1.25 million), the amount by which the Final Net
Assets exceeds such amount.

   You have requested our opinion as to whether the Merger Consideration to be
received by stockholders of the Company in the Transaction is fair, from a
financial point of view, to the Company and its stockholders.



                              Updata Capital. Inc.
    125 Half Mile Road, Red Bank, NJ 07701 o 732-945-l000 fax: 732-945-1001
                             http://www.updata.com

                                      C-1

   For purposes of this opinion, we have assumed that Total Outstanding Shares
equal 41.854 million, including (a) Shares currently outstanding, (b) Shares
resulting from the exercise prior to Closing of stock options or other rights
to acquire Shares granted by the Company or any of its subsidiaries; and, (c)
Shares cancelled in connection with the sale of the Company's ISAC business
(the Information Sharing and Analysis Center division and Open Source
Intelligence division) prior to Closing. We have assumed the completion of the
sale of the ISAC business prior to Closing. Notwithstanding, we do not
consider the impact of the sale of the ISAC business to be material to the
results of our analysis or opinion. We have also assumed that the Adjustment
Amount, when calculated, equals zero dollars; that is, it neither results in a
reduction of nor an increase in Total Consideration.

   Updata Capital, Inc. ("Updata") focuses on providing merger and acquisition
advisory services to information technology ("IT") companies. In this
capacity, we are continually engaged in valuing such businesses, and we
maintain an extensive database of IT mergers and acquisitions and trading data
for comparative purposes.

   Pursuant to an engagement letter dated February 10, 2003, the Company
engaged Updata to act as its financial advisor in connection with the
potential sale of its Global Integrity unit and to provide a fairness opinion
in connection with the sale of the Company.

   In rendering our opinion, we have, among other things, reviewed:

   1) the most recent draft of the Agreement, dated as of April 7, 2003, and
based our opinion on our understanding that the terms and conditions of the
Agreement will not materially change;

   2) the Company's Annual Reports on Form 10-K and related publicly available
financial information for the three fiscal years ended December 31, 2002;

   3) the Company's, internal and ongoing financial results pertaining to the
three months ended March 31, 2003 and financial forecasts for the three month
period ending June 30, 2003;

   4) in discussions with Company senior management certain internal business,
financial and operating information including certain forecasts and an
analysis prepared by the Company regarding a possible liquidation of the
Company's assets following termination of operations;

   5) the Company's market valuation and financial performance compared to
certain publicly traded companies that we deemed to be relevant;

   6) the financial terms and share price premiums in the Transaction compared
to those of certain other public mergers and acquisitions that we deemed to be
relevant;

   7) historical closing share prices and trading volume of the Company's
common stock; and

   8) other public information, and conducted other financial studies, analyses
and investigations as we deemed appropriate for purposes of this opinion.

   In rendering our opinion we have relied, without independent verification,
on the accuracy and completeness of all the financial and other information
(including without limitation the representations and warranties contained in
the Agreement) that was publicly available or furnished to us by the Company.
With respect to financial forecasts and other internal business, financial and
operating information examined by us, we have assumed that these were
reasonably prepared, taking into account information to be included on
disclosure schedules to the Merger Agreement, and reflected the best available
estimates and good faith judgments of Company management as to the financial
performance of and other matters relating to the Company. We have not made an
independent appraisal or valuation of any of the Company's assets nor do we
assume responsibility for or express any view as to financial forecasts or the
assumptions on which they are based.

   In rendering our opinion, we have assumed, with your consent, that the
Merger will be consummated on terms described in the Merger Agreement, without
any waiver of any material terms or conditions by the Company and that
obtaining any regulatory approvals which may be necessary for the Merger will
not have an adverse effect on the Company.


                                      C-2

   Our opinion is necessarily based upon market, economic, financial and other
conditions as they exist and can be evaluated as of the date of this opinion.
Although any change in such conditions or other developments may impact this
opinion, we do not have an obligation to update, revise or reaffirm this
opinion.

   This opinion speaks only as of the date hereof. It is understood that this
opinion is for the information of the Board of Directors of the Company in
connection with its consideration of the Transaction and does not constitute a
recommendation to any Company stockholder as to how such stockholder should
vote on the Transaction. This opinion may not be published or referred to, in
whole or part, without our prior written permission.

   Based upon and subject to the foregoing, we are of the opinion that the
Merger Consideration to be received by the Company's stockholders in the
Transaction is fair, from a financial point of view, to the Company's
stockholders.

                                 Sincerely,



                                 /s/ Updata Capital, Inc.

                                VOTING AGREEMENT


   THIS VOTING AGREEMENT (this "Agreement") is made and entered into as of
April __, 2003 by and between International Network Services, Inc., a Delaware
corporation ("Parent"), and the undersigned stockholder and/or option holder
(the "Stockholder") of Predictive Systems, Inc., a Delaware corporation (the
"Company").

                                   RECITALS:

   A. Parent, the Company and Merger Sub (as defined below) have entered into
an Agreement and Plan of Merger (the "Merger Agreement"), which provides for
the merger (the "Merger") of Mid-West Acquisition Corporation, a wholly-owned
subsidiary of Parent ("Merger Sub") with and into the Company, pursuant to
which all outstanding capital stock of the Company will be converted into the
right to receive a cash payment, as set forth in the Merger Agreement.

   B. The Stockholder is the beneficial owner (as defined in Rule 13d-3 under
the Securities Exchange Act of 1934, as amended (the "Exchange Act")) of such
number of shares of the outstanding capital stock of the Company, and such
number of shares of capital stock of the Company issuable upon the exercise of
outstanding options and warrants, as is indicated on the signature page of
this Agreement.

   C. In consideration of the execution of the Merger Agreement by Parent, the
Stockholder (in his or her capacity as such) has agreed to vote the Shares (as
defined below) and such other shares of capital stock of the Company over
which the Stockholder has voting power, so as to facilitate consummation of
the Merger as provided herein.

   6. Representations and Warranties of the Stockholder. The Stockholder
hereby represents and warrants to Parent that, as of the date hereof and at

subject to any transfers permitted and deemed effected pursuant to Section
2(a) herein) the beneficial owner of the shares of capital stock of the
Company, and the options, warrants and other rights to purchase shares of
capital stock of the Company, set forth on signature page of this Agreement,
with full power to vote or direct the voting of the Shares for and on behalf
of all beneficial owners of the Shares; (ii) the Shares are (and will be) free
and clear of any liens, pledges, security interests, claims, options, rights
of first refusal, co-sale rights, charges or other encumbrances of any kind or
nature (each an "Encumbrance") (other than those Encumbrances which are in
favor of the Company, provided Parent shall have been provided with copies of
the relevant documentation related thereto); (iii) does not (and will not)
beneficially own any securities of the Company other than the shares of
capital stock of the Company, and options, warrants and other rights to
purchase shares of capital stock of the Company, set forth on the signature
page of this Agreement; and (iv) has (and will have) full power and authority
to make, enter into and carry out the terms of this Agreement and the Proxy.

   7. Consent and Waiver. The Stockholder (not in his or her capacity as a

are reasonably required for the consummation of the Merger under the terms of
any agreements to which the Stockholder is a party, or pursuant to any rights
Stockholder may have.

   8. Legending of Shares. If so requested by Parent, the Stockholder hereby
agrees that the Shares shall bear a legend stating that they are subject to
this Agreement and to an irrevocable proxy.

   9. Termination. This Agreement shall terminate and be of no further force
or effect as of the Expiration Date.

   10. Miscellaneous.

   (a) Waiver. No waiver by any party hereto of any condition or any breach of
any term or provision set forth in this Agreement shall not be effective
unless in writing and signed by each party hereto. The waiver of a condition
or any breach of any term or provision of this Agreement shall not operate as
or be construed to be a waiver of any other previous or subsequent breach of
any term or provision of this Agreement.

   (b) Severability. In the event that any term, provision, covenant or
restriction set forth in this Agreement, or the application of any such term,
provision, covenant or restriction to any person, entity or set of
circumstances, shall be determined by a court of competent jurisdiction to be
invalid, unlawful, void or unenforceable to any extent, the remainder of the
terms, provisions, covenants and restrictions set forth in this Agreement, and
the application of such terms, provisions, covenants and restrictions to
persons, entities or circumstances other than those as to which it is
determined to be invalid, unlawful, void or unenforceable, shall remain in
full force and effect, shall not be impaired, invalidated or otherwise
affected and shall continue to be valid and enforceable to the fullest extent
permitted by applicable law.

   (c) Binding Effect; Assignment. This Agreement and all of the terms and
provisions hereof shall be binding upon, and inure to the benefit of, the
parties hereto and their respective successors and permitted assigns, but,
except as otherwise specifically provided herein, neither this Agreement nor
any of the rights, interests or obligations of the Stockholder may be assigned
to any other person without the prior written consent of Parent.

   (d) Amendments. This Agreement may not be modified, amended, altered or
supplemented, except upon the execution and delivery of a written agreement
executed by each of the parties hereto.

   (e) Specific Performance; Injunctive Relief. Each of the parties hereto
hereby acknowledge that (i) the representations, warranties, covenants and
restrictions set forth in this Agreement are necessary, fundamental and
required for the protection of Parent and to preserve for Parent the benefits
of the Merger; (ii) such

                                      E-3

covenants relate to matters which are of a special, unique, and extraordinary
character that gives each such representation, warranty, covenant and
restriction a special, unique, and extraordinary value; and (iii) a breach of
any such representation, warranty, covenant or restriction, or any other term
or provision of this Agreement, will result in irreparable harm and damages to
Parent which cannot be adequately compensated by a monetary award.
Accordingly, Parent and the Stockholder hereby expressly agree that in
addition to all other remedies available at law or in equity, Parent shall be
entitled to the immediate remedy of specific performance, a temporary and/or
permanent restraining order, preliminary injunction, or such other form of
injunctive or equitable relief as may be used by any court of competent
jurisdiction to restrain or enjoin any of the parties hereto from breaching
any representations, warranties, covenants or restrictions set forth in this
Agreement, or to specifically enforce the terms and provisions hereof.

   (f) Governing Law. This Agreement shall be governed by and construed,
interpreted and enforced in accordance with the laws of the State of Delaware
without giving effect to any choice or conflict of law provision, rule or
principle (whether of the State of Delaware or any other jurisdiction) that
would cause the application of the laws of any jurisdiction other than the
State of Delaware.

   (f) Entire Agreement. This Agreement and the Proxy and the other agreements
referred to in this Agreement set forth the entire agreement and understanding
of Parent and the Stockholder with respect to the subject matter hereof and
thereof, and supersede all prior discussions, agreements and understandings
between Parent and the Stockholder, both oral and written, with respect to the
subject matter hereof and thereof.
