ITEM 4.  DESCRIPTION OF THE SUBORDINATED UNITS.

     The subordinated units are a separate class of interests in the
partnership, and the rights of holders of such interests to participate in
distributions to partners differ from, and are subordinated to, the rights of
the holders of common units. For any given quarter, any available cash will
first be distributed to the general partner and to the holders of common units,
and then will be distributed to the holders of subordinated units depending upon
the amount of available cash for the quarter, the amount of common unit
arrearages, if any, and other factors discussed below.

CONVERSION OF SUBORDINATED UNITS

     The subordination period will generally extend from the closing of the
initial public offering, dated November 23, 1998, until the first day of any
quarter beginning after December 31, 2003 in respect of which (i) distributions
of available cash from operating surplus on the common units and the
subordinated units with respect to each of the three consecutive four-quarter
periods immediately preceding such date equaled or exceeded the sum of the
minimum quarterly distribution on all of the outstanding common units and
subordinated units during such periods, (ii) the adjusted operating surplus
generated during each of the three consecutive four-quarter periods immediately
preceding such date equaled or exceeded the sum of the minimum quarterly
distribution on all of the common units and subordinated units that were
outstanding on a fully diluted basis and the related distribution on the general
partner interests in the partnership and the operating partnership during such
periods, and (iii) there are no outstanding common unit arrearages.

     Prior to the end of the subordination period and to the extent the tests
for conversion described below are satisfied, a portion of the subordinated
units may be eligible to convert into common units prior to December 31, 2003.
Subordinated units will convert into common units on a one-for-one basis on the
first day after the record date established for the distribution in respect of
any quarter ending on or after December 31, 2002 with respect to one-quarter of
the subordinated units outstanding, in respect of which (i) distributions of
available cash from operating surplus on the common units and the subordinated
units with respect to each of the three consecutive four-quarter periods
immediately preceding such date equaled or exceeded the sum of the minimum
quarterly distribution on all of the outstanding common units and subordinated
units during such periods, (ii) the adjusted operating surplus generated during
each of the three consecutive four-quarter periods immediately preceding such
date equaled or exceeded the sum of the minimum quarterly distribution on all of
the common units and subordinated units that were outstanding on a fully diluted
basis and the related distribution on the general partner interests in the
partnership during such periods and (iii) there are no outstanding common unit
arrearages.

     Upon expiration of the subordination period, all remaining subordinated
units will convert into common units on a one-for-one basis and will thereafter
participate, pro rata, with the other common units in distributions of available
cash. In addition, if the general partner of the partnership is removed as
general partner of the partnership under circumstances where cause does not
exist and units held by the general partner and its affiliates are not voted in
favor of such removal, (i) the subordination period will end and all outstanding
subordinated units will immediately convert into common units on a one-for-one
basis, (ii) any existing common unit arrearages will be extinguished and (iii)
the general partner will have the right to convert its general partner interests
(and the right to receive incentive distributions) into common units or to
receive cash in exchange for such interests.




                                       3


LIMITED VOTING RIGHTS

     Holders of subordinated units will generally vote as a class separate from
the holders of common units and will have very limited voting rights. During the
subordination period, common units and subordinated units each vote separately
as a class on the following matters: (i) a sale or exchange of all or
substantially all of the partnership's assets, (ii) the election of a successor
general partner, (iii) a dissolution or reconstitution of the partnership, (iv)
a merger of the partnership, (v) issuance of limited partner interests in
certain circumstances and (vi) certain amendments to the partnership agreement,
including any amendment that would cause the partnership to be treated as an
association taxable as a corporation. The subordinated units are not entitled to
vote on approval of certain actions of the general partner (including the
withdrawal of the general partner or the transfer by the general partner of its
general partner interest or incentive distribution rights under certain
circumstances). Removal of the general partner requires a two-thirds vote of all
outstanding units. Under the partnership agreement, the general partner
generally will be permitted to effect amendments to the partnership agreement
that do not materially adversely affect unitholders.

DISTRIBUTIONS UPON LIQUIDATION

     If the partnership liquidates during the subordination period, under
certain circumstances holders of outstanding common units will be entitled to
receive more per unit in liquidating distributions than holders of outstanding
subordinated units. The per unit difference will be dependent upon the amount of
gain or loss recognized by the partnership in liquidating its assets. Following
conversion of the subordinated units into common units, all units will be
treated the same upon liquidation of the partnership.

     This Description of the Subordinated Units contains terms that are defined
in the partnership agreement. For a more complete understanding of these terms,
please review the partnership agreement attached as Exhibit 3.1 to the Current
Report of Form 8-K filed August 27, 2001 and incorporated herein by reference.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

     Not applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 17-108 of the Delaware Revised Limited Partnership Act empowers a
Delaware limited partnership to indemnify and hold harmless any partner or other
person from and against all claims and demands whatsoever. The partnership
agreement of Plains All American Pipeline provides that Plains All American
Pipeline will indemnify the general partner, any departing partner, any person
who is or was an affiliate of the general partner or any departing partner, and
any person who is or was an officer, director, partner or trustee of the general
partner or any departing partner or any affiliate of the general partner or any
departing partner, or any person who is or was serving at the request of the
general partner or any departing partner or any affiliate of the general partner
or any departing partner as an officer, director, employee, partner, agent or
trustee of another person (each, an "Indemnitee"), to the fullest extent
permitted by law, from and against any and all losses, claims, damages,
liabilities (joint and several), expenses (including, without limitation, legal
fees and expenses), judgments, fines, penalties, interest, settlements and other
amounts arising from any and all claims, demands, actions, suits or proceedings,
whether civil, criminal, administrative or investigative, in which any
Indemnitee may be involved, or is threatened to be involved, as a party or
otherwise, by reason of its status as any of the foregoing; provided that in
each case the Indemnitee acted in good faith and in a manner that such
Indemnitee reasonably believed to be in or not opposed to the best interests of
Plains All American Pipeline and, with respect to any criminal proceeding, had
no reasonable cause to believe its conduct was unlawful. Any indemnification
under these provisions will be only out of the assets of Plains All American
Pipeline, and the general partner shall not be personally liable for, or have
any obligation to contribute or loan funds or



                                       4


assets to Plains All American Pipeline to enable it to effectuate, such
indemnification. Plains All American Pipeline is authorized to purchase (or to
reimburse the general partner or its affiliates for the cost of) insurance
against liabilities asserted against and expenses incurred by such persons in
connection with Plains All American Pipeline's activities, regardless of whether
Plains All American Pipeline would have the power to indemnify such person
against such liabilities under the provisions described above.

     The underwriting agreements that the partnership may enter into with
respect to the offer and sale of securities covered by this registration
statement will contain certain provisions for the indemnification of directors
and officers of the partnership and the underwriters or sales agent, as
applicable, against civil liabilities under the Securities Act.

ITEM 7.  EXEMPTION FROM REGISTRATION CLAIMED.

ITEM 9.  UNDERTAKINGS.

     The undersigned registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
     a post-effective amendment to this registration statement:

              (a) To include any prospectus required by Section 10(a)(3) of the
         Securities Act;

              (b) To reflect in the prospectus any facts or events arising after
         the effective date of this registration statement (or the most recent
         post-effective amendment hereof) which, individually or in the
         aggregate, represent a fundamental change in the information set forth
         in this registration statement. Notwithstanding the foregoing, any
         increase or decrease in volume of securities offered (if the total
         dollar value of securities offered would not exceed that which was
         registered) and any deviation from the low or high end of the estimated
         maximum offering range may be reflected in the form of prospectus filed
         with the Securities and Exchange Commission pursuant to Rule 424(b) if,
         in the aggregate, the changes in volume and price



                                       5


         represent no more than a 20% change in the maximum aggregate offering
         price set forth in the "Calculation of Registration Fee" table in the
         effective registration statement;

              (c) To include any material information with respect to the plan
         of distribution not previously disclosed in this registration statement
         or any material change to such information in this registration
         statement;

     provided, however, that paragraphs (1)(a) and (1)(b) do not apply if the
     information required to be included in a post-effective amendment by those
     paragraphs is contained in periodic reports filed by the registrant
     pursuant to Section 13 or Section 15(d) of the Exchange Act that are
     incorporated by reference in this registration statement.

         (2) That, for the purpose of determining any liability under the
     Securities Act, each such post-effective amendment shall be deemed to be a
     new registration statement relating to the securities offered therein, and
     the offering of such securities at that time shall be deemed to be the
     initial bona fide offering thereof.

         (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.

         (4) That, for the purposes of determining any liability under the
     Securities Act, each filing of the registrant's annual report pursuant to
     Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable,
     each filing of an employee benefit plan's annual report pursuant to Section
     15(d) of the Exchange Act) that is incorporated by reference in this
     registration statement shall be deemed to be a new registration statement
     relating to the securities offered therein, and the offering of such
     securities at that time shall be deemed to be the initial bona fide
     offering thereof.

         (5) Insofar as indemnification for liabilities arising under the
     Securities Act may be permitted to directors, officers and controlling
     persons of the registrant pursuant to the foregoing provisions, or
     otherwise, the registrant has been advised that in the opinion of the
     Securities and Exchange Commission such indemnification is against public
     policy as expressed in the Securities Act and is, therefore, unenforceable.
     In the event that a claim for indemnification against such liabilities
     (other than the payment by the registrant of expenses incurred or paid by a
     director, officer or controlling person of the registrant in the successful
     defense of any action, suit or proceeding) is asserted by such director,
     officer or controlling person in connection with the securities being
     registered, the registrant will, unless in the opinion of its counsel the
     matter has been settled by controlling precedent, submit to a court of
     appropriate jurisdiction the question whether such indemnification by it is
     against public policy as expressed in the Securities Act and will be
     governed by the final adjudication of such issue.
