Plains All American Pipeline, L.P.

   We are a publicly traded Delaware limited partnership engaged in interstate
and intrastate marketing, transportation and terminalling of crude oil and
marketing of liquefied petroleum gas, or LPG. We have an extensive network in
the United States and Canada of pipeline transportation, storage and gathering
assets in key oil producing basins and at major market hubs. Several members of
our existing management team founded this midstream crude oil business in 1992
and we completed our initial public offering in 1998. Our operations are
concentrated in Texas, California, Oklahoma and Louisiana and in the Canadian
provinces of Alberta and Saskatchewan.

   Our executive offices are located at 333 Clay Street, Suite 1600, Houston,
Texas 77002 and our telephone number is (713) 646-4100.

                              The Exchange Offer

   On September 25, 2002, we completed a private offering of the outstanding
notes. We entered into a registration rights agreement with the initial
purchaser in the private offering in which we agreed to deliver to you this
prospectus and to use our reasonable best efforts to complete the exchange
offer within 210 days after the date we issued the outstanding notes.

Exchange Offer..............  We are offering to exchange new notes for
                              outstanding notes.

Expiration Date.............  The exchange offer will expire at 5:00 p.m. New
                              York City time, on           , 2002, unless we
                              decide to extend it.

Condition to the Exchange
  Offer.....................  The registration rights agreement does not
                              require us to accept outstanding notes for
                              exchange if the exchange offer or the making of
                              any exchange by a holder of the outstanding notes
                              would violate any applicable law or
                              interpretation of the staff of the SEC. A minimum
                              aggregate principal amount of outstanding notes
                              being tendered is not a condition to the exchange
                              offer.

Procedures for Tendering
  Outstanding Notes.........  To participate in the exchange offer, you must
                              complete, sign and date the letter of
                              transmittal, or a facsimile of the letter of
                              transmittal, and transmit it together with all
                              other documents required by the letter of
                              transmittal, including the outstanding notes that
                              you wish to exchange, to Wachovia Bank, National
                              Association, as exchange agent, at the address
                              indicated on the cover page of the letter of
                              transmittal. In the alternative, you can tender
                              your outstanding notes

Consequences of Failure to
  Exchange Outstanding Notes  If you do not exchange your outstanding notes in
                              this exchange offer, you will no longer be able
                              to require us to register the outstanding notes
                              under the Securities Act except in the limited
                              circumstances provided under our registration
                              rights agreement. In addition, you will not be
                              able to resell, offer to resell or otherwise
                              transfer the outstanding notes unless we have
                              registered the outstanding notes under the
                              Securities Act, or unless you resell, offer to
                              resell or otherwise transfer them under an
                              exemption from the registration requirements of,
                              or in a transaction not subject to, the
                              Securities Act.

U.S. Federal Income Tax
  Considerations............  The exchange of new notes for outstanding notes
                              in the exchange offer should not be a taxable

Ranking.....................  The new notes are unsecured. The new notes rank
                              equally in right of payment with all of our other
                              existing and future senior unsecured debt and
                              senior in right of payment to all of our future
                              subordinated debt.

Restrictive Covenants.......  The indenture governing the notes will contain
                              covenants that limit our ability and our
                              restricted subsidiaries' ability to, among other
                              things:

                             .   incur additional indebtedness;

                             .   make investments and other restricted payments;

                             .   create restrictions on the payment of
                                 dividends or other amounts to us from our
                                 restricted subsidiaries;

                             .   incur liens;

                             .   engage in transactions with affiliates;

                             .   sell assets; and

                             .   consolidate, merge or transfer assets.

                              Each covenant contains a number of important
                              exceptions and qualifications that are described
                              in the "Description of the New Notes" section of
                              this prospectus. Many of the covenants will
                              terminate if at least two of three specified
                              rating agencies assign the notes an investment
                              grade rating.

Transfer Restrictions;
  Absence of a Public Market
  for the Notes.............  The new notes generally will be freely
                              transferable, but will also be new securities for
                              which there will not initially be a market. There
                              can be no assurance as to the development or
                              liquidity of any market for the new notes.

                                 RISK FACTORS

   In addition to the other information set forth elsewhere or incorporated by
reference in this prospectus, the following factors relating to our partnership
and the exchange offer and the new notes should be considered carefully in
deciding whether to participate in the exchange offer.

Risks Related to Our Business

   The level of our profitability is dependent upon an adequate supply of crude
oil from fields located offshore and onshore California. Production from these
offshore fields has experienced substantial production declines since 1995.

   A significant portion of our gross margin is derived from pipeline
transportation margins associated with the Santa Ynez and Point Arguello fields
located offshore California. We expect that there will continue to be natural
production declines from each of these fields as the underlying reservoirs are
depleted. A 5,000 barrel per day decline in volumes shipped from these fields
would result in a decrease in annual pipeline tariff revenues of approximately
$3.2 million. In addition, any production disruption from these fields due to
production problems, transportation problems or other reasons would have a
material adverse effect on our business.

   Potential future acquisitions and expansions, if any, may affect our
business by substantially increasing the level of our indebtedness and
contingent liabilities and increasing our risks of being unable to effectively
integrate these new operations.

   Making acquisitions is an integral component of our business strategy.
Accordingly, from time to time, we evaluate and acquire assets and businesses
that we believe complement our existing assets and businesses. The Shell
acquisition represents a significant acquisition for us and, as a result, we
may encounter difficulties integrating this acquisition with our existing
business and our other recent acquisitions and successfully managing the rapid
growth we expect to experience from these acquisitions. Acquisitions may
require substantial capital or the incurrence of substantial indebtedness. If
we consummate any future acquisitions, our capitalization and results of
operations may change significantly, and you will not have the opportunity to
evaluate the economic, financial and other relevant information that we will
consider in determining the application of these funds and other resources.

   Our crude oil marketing business requires extensive credit risk management
that may not be adequate to protect against customer nonpayment.

   As a result of business failures, revelations of material misrepresentations
and related financial restatements by several large, well-known companies in
various industries over the past year, there have been significant disruptions
and extreme volatility in the financial markets and credit markets. Because of
the credit intensive nature of the energy industry and troubling disclosures by
several large, diversified energy companies, the energy industry has been
especially impacted by these developments, with the rating agencies downgrading
a number of large, energy related companies. Accordingly, in this environment
we are exposed to an increased level of direct and indirect counter-party
credit and performance risk. There can be no assurance that we have adequately
assessed the credit worthiness of our existing or future counter-parties or
that there will not be an unanticipated deterioration in their credit
worthiness, which could have an adverse impact on us.

   The profitability of our pipeline operations depends on the volume of crude
oil shipped by third parties.

   Third party shippers generally do not have long-term contractual commitments
to ship crude oil on our pipelines. A decision by a shipper to substantially
reduce or cease to ship volumes of crude oil on our pipelines could cause a
significant decline in our revenues. For example, an average 25,000 barrel per
day variance in the Basin Pipeline System, the primary asset we acquired from
Shell, equivalent to an approximate 9% volume variance on that pipeline system,
would result in an approximate $3.4 million change in annualized gross margin.

                                      6

   In 1999, we suffered a large loss from unauthorized crude oil trading by a
former employee. A loss of this kind could occur again in the future in spite
of our best efforts to prevent it.

   Generally, it is our policy that as we purchase crude oil, we establish a
margin by selling crude oil for physical delivery to third party users, such as
independent refiners or major oil companies, or by entering into a future
delivery obligation under futures contracts on the NYMEX. Through these
transactions, we seek to maintain a position that is substantially balanced
between purchases, on the one hand, and sales or future delivery obligations,
on the other hand. Our policy is not to acquire and hold crude oil, futures
contracts or derivative products for the purpose of speculating on price
changes. We discovered in November 1999 that this policy was violated by one of
our former employees, which resulted in losses of approximately $174.0 million,
including estimated costs and legal expenses. In 2000, we recognized an
additional charge of approximately $7.0 million for litigation related to the
unauthorized trading losses. We have taken steps within our organization to
enhance our processes and procedures to prevent future unauthorized trading. We
cannot assure you, however, that these steps will detect and prevent all
violations of our trading policies and procedures, particularly if deception or
other intentional misconduct is involved.

   The success of our business strategy to increase and optimize throughput on
our pipeline and gathering assets is dependent upon our securing additional
supplies of crude oil.

   Our operating results are dependent upon securing additional supplies of
crude oil from increased production by oil companies and aggressive lease
gathering efforts. The ability of producers to increase production is dependent
on the prevailing market price of oil, the exploration and production budgets
of the major and independent oil companies, the depletion rate of existing
reservoirs, the success of new wells drilled, environmental concerns,
regulatory initiatives and other matters beyond our control. There can be no
assurance that production of crude oil will rise to sufficient levels to cause
an increase in the throughput on our pipeline and gathering assets.

   Our operations are dependent upon demand for crude oil by refiners in the
Midwest and on the Gulf Coast. Any decrease in this demand could adversely
affect our business.

   Demand also depends on the ability and willingness of shippers having access
to our transportation assets to satisfy their demand by deliveries through
those assets, and any decrease in this demand could adversely affect our
business. Demand for crude oil is dependent upon the impact of future economic
conditions, fuel conservation measures, alternative fuel requirements,
governmental regulation or technological advances in fuel economy and energy
generation devices, all of which could reduce demand.

   We face intense competition in our terminalling and storage activities and
gathering and marketing activities.

   Our competitors include other crude oil pipelines, the major integrated oil
companies, their marketing affiliates, and independent gatherers, brokers and
marketers of widely varying sizes, financial resources and experience. Some of
these competitors have capital resources many times greater than ours and
control substantially greater supplies of crude oil.

   The profitability of our gathering and marketing activities depends
primarily on the volumes of crude oil we purchase and gather.

   To maintain the volumes of crude oil we purchase, we must continue to
contract for new supplies of crude oil to offset volumes lost because of
natural declines in crude oil production from depleting wells or volumes lost
to competitors. Replacement of lost volumes of crude oil is particularly
difficult in an environment where production is low and competition to gather
available production is intense. Generally, because producers experience
inconveniences in switching crude oil purchasers, such as delays in receipt of
proceeds while awaiting the preparation of new division orders, producers
typically do not change purchasers on the basis of minor variations in price.
Thus, we may experience difficulty acquiring crude oil at the wellhead in areas
where there

                                      7

<PAGE>

are existing relationships between producers and other gatherers and purchasers
of crude oil. We estimate that a 5,000 barrel per day decrease in barrels
gathered by us would have an approximate $900,000 per year negative impact on
gross margin. This impact is based on a reasonable margin throughout various
market conditions. Actual margins vary based on the location of the crude oil,
the strength or weakness of the market and the grade or quality of crude oil.

   We are exposed to the credit risk of our customers in the ordinary course of
our gathering and marketing activities.

   In those cases where we provide division order services for crude oil
purchased at the wellhead, we may be responsible for distribution of proceeds
to all parties. In other cases, we pay all of or a portion of the production
proceeds to an operator who distributes these proceeds to the various interest
owners. These arrangements expose us to operator credit risk, and there can be
no assurance that we will not experience losses in dealings with other parties.

   Our operations are subject to federal and state environmental and safety
laws and regulations relating to environmental protection and operational
safety.

   Our pipeline, gathering, storage and terminalling facilities operations are
subject to the risk of incurring substantial environmental and safety related
costs and liabilities. These costs and liabilities could arise under
increasingly strict environmental and safety laws, including regulations and
enforcement policies, or claims for damages to property or persons resulting
from our operations. If we were not able to recover such resulting costs
through insurance or increased tariffs and revenues, our ability to pay
principal and interest on the notes could be adversely affected.

   The transportation and storage of crude oil results in a risk that crude oil
and other hydrocarbons may be suddenly or gradually released into the
environment, potentially causing substantial expenditures for a response
action, significant government penalties, liability to government agencies for
natural resources damages, liability to private parties for personal injury or
property damages, and significant business interruption.

   Our Canadian pipeline assets are subject to federal and provincial
regulation.

   Our Canadian pipeline assets are subject to regulation by the National
Energy Board and by provincial agencies in Saskatchewan and Alberta. With
respect to a pipeline over which it has jurisdiction, each of these agencies
has the power to determine the rates we are allowed to charge for
transportation on such pipeline. The extent to which regulatory agencies can
override existing transportation contracts has not been fully decided.

   Our pipeline systems are dependent upon their interconnections with other
crude oil pipelines to reach end markets.

   Reduced throughput on these interconnecting pipelines as a result of
testing, line repair, reduced operating pressures or other causes could result
in reduced throughput on our pipeline systems that would adversely affect our
profitability.

Risks Related to the Exchange Offer and the Notes

   If you do not properly tender your outstanding notes, you will continue to
hold unregistered outstanding notes and your ability to transfer outstanding
notes will be adversely affected.

   We will only issue new notes in exchange for outstanding notes that you
timely and properly tender. Therefore, you should allow sufficient time to
ensure timely delivery of the outstanding notes and you should carefully follow
the instructions on how to tender your outstanding notes. Neither we nor the
exchange agent is required to tell you of any defects or irregularities with
respect to your tender of outstanding notes.

                                      8

<PAGE>

   If you do not exchange your outstanding notes for new notes pursuant to the
exchange offer, the outstanding notes you hold will continue to be subject to
the existing transfer restrictions. In general, you may not offer or sell the
outstanding notes except under an exemption from, or in a transaction not
subject to, the Securities Act and applicable state securities laws. We do not
plan to register outstanding notes under the Securities Act unless our
registration rights agreement with the initial purchaser of the outstanding
notes requires us to do so. Further, if you continue to hold any outstanding
notes after the exchange offer is consummated, you may have trouble selling
them because there will be fewer notes outstanding.

   We have a structure in which our subsidiaries conduct our operations and own
our operating assets.

   Our subsidiaries conduct all of our operations and own all of our operating
assets. We have no significant assets other than the partnership interests and
the equity in our subsidiaries. As a result, our ability to make required
payments on the notes depends on the performance of our subsidiaries and their
ability to distribute funds to us. The ability of our subsidiaries to make
distributions to us may be restricted by, among other things, credit facilities
and applicable state partnership laws and other laws and regulations. Pursuant
to the credit facilities, we may be required to establish cash reserves for the
future payment of principal and interest on the amounts outstanding under the
credit facilities. If we are unable to obtain the funds necessary to pay the
principal amount at maturity of the notes, or to repurchase the notes upon the
occurrence of a change of control, we may be required to adopt one or more
alternatives, such as a refinancing of the notes. We cannot assure you that we
would be able to refinance the notes.

   Your right to receive payments on the notes and the guarantees is unsecured
and will be effectively subordinated to our existing and future secured
indebtedness.

   The notes are effectively subordinated to claims of our secured creditors
and the guarantees are effectively subordinated to the claims of our secured
creditors as well as the secured creditors of our subsidiary guarantors.
Although substantially all of our subsidiaries, other than PAA Finance Corp.,
the co-issuer of the notes, will initially guarantee the notes, in the future,
under certain circumstances, the guarantees are subject to release and we may
have subsidiaries that are not guarantors. In that case, the notes would be
effectively subordinated to the claims of all creditors, including trade
creditors and tort claimants, of our subsidiaries that are not guarantors. In
the event of the insolvency, bankruptcy, liquidation, reorganization,
dissolution or winding up of the business of a subsidiary that is not a
guarantor, creditors of that subsidiary would generally have the right to be
paid in full before any distribution is made to us or the holders of the notes.

   We have substantial leverage that may limit our ability to borrow additional
funds, comply with the terms of our indebtedness or capitalize on business
opportunities.

   Our leverage is significant in relation to our partners' capital. As of
September 30, 2002, our total outstanding long-term debt, including current
maturities, was approximately $509.1 million. See "Capitalization." We will be
prohibited from making cash distributions during an event of default under any
of our indebtedness. Various limitations in our credit facilities may reduce
our ability to incur additional debt, to engage in some transactions and to
capitalize on business opportunities. Any subsequent refinancing of our current
indebtedness or any new indebtedness could have similar or greater restrictions.

   Our leverage could have important consequences to investors in the notes. We
will require substantial cash flow to meet our principal and interest
obligations with respect to the notes and our other consolidated indebtedness.
Our ability to make scheduled payments, to refinance our obligations with
respect to our indebtedness or our ability to obtain additional financing in
the future will depend on our financial and operating performance, which, in
turn, is subject to prevailing economic conditions and to financial, business
and other factors. We believe that we will have sufficient cash flow from
operations and available borrowings under our bank credit facility to service
our indebtedness, although the principal amount of the notes will likely need
to be refinanced at maturity in whole or in part. However, a significant
downturn in the hydrocarbon industry or other

                                      9

<PAGE>

development adversely affecting our cash flow could materially impair our
ability to service our indebtedness. If our cash flow and capital resources are
insufficient to fund our debt service obligations, we may be forced to
refinance all or a portion of our debt or sell assets. We cannot assure you
that we would be able to refinance our existing indebtedness or sell assets on
terms that are commercially reasonable.

   The instruments governing our debt contain restrictive covenants that may
prevent us from engaging in certain beneficial transactions. The agreements
governing our debt generally require us to comply with various affirmative and
negative covenants including the maintenance of certain financial ratios and
restrictions on incurring additional debt, entering into mergers,
consolidations and sales of assets, making investments and granting liens. Our
leverage may adversely affect our ability to fund future working capital,
capital expenditures and other general partnership requirements, future
acquisition, construction or development activities, or to otherwise fully
realize the value of our assets and opportunities because of the need to
dedicate a substantial portion of our cash flow from operations to payments on
our indebtedness or to comply with any restrictive terms of our indebtedness.
Our leverage may also make our results of operations more susceptible to
adverse economic and industry conditions by limiting our flexibility in
planning for, or reacting to, changes in our business and the industry in which
we operate and may place us at a competitive disadvantage as compared to our
competitors that have less debt.

   We may not be able to fund a change of control offer.

   In the event of a change of control, we will be required, subject to certain
conditions, to offer to purchase all outstanding notes at a price equal to 101%
of the principal amount thereof, plus accrued and unpaid interest thereon to
the date of purchase. If a change of control were to occur today, we would not
have sufficient funds available to purchase all of the outstanding notes were
they to be tendered in response to an offer made as a result of a change of
control. We cannot assure you that we will have sufficient funds available or
that we will be permitted by our other debt instruments to fulfill these
obligations upon a change of control in the future. Furthermore, certain change
of control events would constitute an event of default under our current bank
credit facilities. See "Description of the New Notes--Repurchase at the Option
of Holders--Change of Control."

   A court may use fraudulent conveyance considerations to avoid or subordinate
the subsidiary guarantees.

   Various applicable fraudulent conveyance laws have been enacted for the
protection of creditors. A court may use fraudulent conveyance laws to
subordinate or avoid the subsidiary guarantees of the notes issued by any of
our subsidiary guarantors. It is also possible that under certain circumstances
a court could hold that the direct obligations of a subsidiary guaranteeing the
notes could be superior to the obligations under that guarantee.

   A court could avoid or subordinate the guarantee of the notes by any of our
subsidiaries in favor of that subsidiary's other debts or liabilities to the
extent that the court determined either of the following were true at the time
the subsidiary issued the guarantee:

  .   that subsidiary incurred the guarantee with the intent to hinder, delay
      or defraud any of its present or future creditors or that subsidiary
      contemplated insolvency with a design to favor one or more creditors to
      the total or partial exclusion of others; or

  .   that subsidiary did not receive fair consideration or reasonable
      equivalent value for issuing the guarantee and, at the time it issued the
      guarantee, that subsidiary:

     .   was insolvent or rendered insolvent by reason of the issuance of the
         guarantee;

     .   was engaged or about to engage in a business or transaction for which
         the remaining assets of that subsidiary constituted unreasonably small
         capital; or

     .   intended to incur, or believed that it would incur, debts beyond its
         ability to pay such debts as they matured.

                                      10

<PAGE>

   The measure of insolvency for purposes of the foregoing will vary depending
upon the law of the relevant jurisdiction. Generally, however, an entity would
be considered insolvent for purposes of the foregoing if the sum of its debts,
including contingent liabilities, were greater than the fair saleable value of
all of its assets at a fair valuation, or if the present fair saleable value of
its assets were less than the amount that would be required to pay its probable
liability on its existing debts, including contingent liabilities, as they
become absolute and matured.

   Among other things, a legal challenge of a subsidiary's guarantee of the
notes on fraudulent conveyance grounds may focus on the benefits, if any,
realized by that subsidiary as a result of our issuance of the notes. To the
extent a subsidiary's guarantee of the notes is avoided as a result of
fraudulent conveyance or held unenforceable for any other reason, the note
holders would cease to have any claim in respect of that guarantee.

   Your ability to transfer the notes may be limited by the absence of a
trading market.

   The notes will be new securities for which currently there is no trading
market. We do not currently intend to apply for listing of the notes on any
securities exchange or stock market. Although the initial purchaser has
informed us that it currently intends to make a market in the notes, it is not
obligated to do so. In addition, the initial purchaser may discontinue any such
market making at any time without notice. The liquidity of any market for the
notes will depend on the number of holders of those notes, the interest of
securities dealers in making a market in those notes and other factors.
Accordingly, we cannot assure you as to the development or liquidity of any
market for the notes. Historically, the market for noninvestment grade debt has
been subject to disruptions that have caused substantial volatility in the
prices of securities similar to the notes. We cannot assure you that the
market, if any, for the notes will be free from similar disruptions. Any such
disruption may adversely affect the note holders.

   We do not have the same flexibility as other types of organizations to
accumulate cash, which may limit cash available to service the notes or to
repay them at maturity.

   Unlike a corporation, our partnership agreement requires us to distribute,
on a quarterly basis, 100% of our available cash to our unitholders of record
and our general partner. Available cash is generally all of our cash receipts
adjusted for cash distributions and net changes to reserves. Our general
partner will determine the amount and timing of such distributions and has
broad discretion to establish and make additions to our reserves or the
reserves of our operating partnerships in amounts the general partner
determines in its reasonable discretion to be necessary or appropriate:

  .   to provide for the proper conduct of our business and the businesses of
      our operating partnerships (including reserves for future capital
      expenditures and for our anticipated future credit needs),

  .   to provide funds for distributions to our unitholders and the general
      partner for any one or more of the next four calendar quarters, or

  .   to comply with applicable law or any of our loan or other agreements.

   Although our payment obligations to our unitholders are subordinate to our
payment obligations to you, the value of our units will decrease in direct
correlation with decreases in the amount we distribute per unit. Accordingly,
if we experience a liquidity problem in the future, we may not be able to issue
equity to recapitalize.

                                EXCHANGE OFFER

Purpose and Effect of the Exchange Offer

   In connection with the issuance of the outstanding notes, we entered into a
registration rights agreement. Under the registration rights agreement, we
agreed to use our reasonable best efforts to:

  .   within 60 days after the original issuance of the outstanding notes on
      September 25, 2002, file a registration statement with the SEC with
      respect to a registered offer to exchange each outstanding note for a new
      note having terms substantially identical in all material respects to
      such note except that the new note will not contain terms with respect to
      transfer restrictions or penalty interest; and

  .   cause the registration statement to be declared effective under the
      Securities Act within 180 days after the original issuance of the
      outstanding notes.

   We have further agreed to offer the new notes in exchange for surrender of
the outstanding notes promptly following the effectiveness of the registration
statement and to keep the exchange offer open for not less than 20 business
days (or longer if required by applicable law) after the date notice of the
exchange offer is mailed to the holders of the outstanding notes.

   We have fulfilled the agreements described in the two preceding bullet
points and are now offering eligible holders of the outstanding notes the
opportunity to exchange their outstanding notes for new notes registered under
the Securities Act. Holders are eligible if they are not prohibited by any law
or policy of the SEC from participating in this exchange offer. The new notes
will be substantially identical to the outstanding notes except that the new
notes will not contain terms with respect to transfer restrictions,
registration rights or additional interest.

   Under limited circumstances, we agreed to use our reasonable best efforts to
cause the SEC to declare effective a shelf registration statement for the
resale of the outstanding notes. We also agreed to use our reasonable best
efforts to keep the shelf registration statement effective for up to two years
after its effective date. The circumstances include if:

  .   a change in law or in applicable interpretations thereof of the staff of
      the SEC do not permit us to effect the exchange offer;

  .   for any other reason the exchange offer is not consummated within 360
      days from September 25, 2002, the date of the original issuance of the
      outstanding notes;

  .   the initial purchaser notifies us following consummation of the exchange
      offer that outstanding notes held by it are not eligible to be exchanged
      for new notes in the exchange offer; or

  .   any holder other than the initial purchaser is not eligible to
      participate in the exchange offer.

   We will pay additional cash interest on the applicable outstanding notes,
subject to certain exceptions:

  .   if the exchange offer registration statement is not filed with the SEC on
      or before the 60th day after the original issuance of the outstanding
      notes;

  .   if the exchange offer registration statement is not declared effective by
      the SEC on or before the 180th day after the original issuance of the
      outstanding notes;

  .   if the exchange offer is not consummated on or before the 210th day after
      September 25, 2002, the date of the original issuance of the outstanding
      notes;

                                      12

<PAGE>

  .   if obligated to file a shelf registration statement, we fail to file the
      shelf registration statement with the SEC on or prior to the 60th day
      after the date on which the obligation to file a shelf registration
      statement arises;

  .   if obligated to file a shelf registration statement, the shelf
      registration statement is not declared effective on or prior to the 180th
      day after the date on which the obligation to file a shelf registration
      statement arises; or

  .   after this registration statement or the shelf registration statement, as
      the case may be, is declared effective, such registration statement
      thereafter ceases to be effective (subject to certain exceptions) (each
      such event referred to in the preceding clauses being a "registration
      default");

from and including the date on which any such registration default occurs to
the date on which all registration defaults have been cured.

   The rate of the additional interest will be 0.25% per year for the first
90-day period immediately following the occurrence of a registration default,
and such rate will increase by an additional 0.25% per year with respect to
each subsequent 90-day period until all registration defaults have been cured,
up to a maximum additional interest rate of 1.0% per year. We will pay such
additional interest on regular interest payment dates. Such additional interest
will be in addition to any other interest payable from time to time with
respect to the outstanding notes and the new notes.

   Upon the filing or effectiveness of this registration statement, the
consummation of the exchange offer, the filing or effectiveness of a shelf
registration statement, or the effectiveness of a succeeding registration
statement, as the case may be, the interest rate borne by the notes from the
date of such effectiveness or consummation, as the case may be, will be reduced
to the original interest rate. However, if after any such reduction in interest
rate, a different event specified in the clauses above occurs, the interest
rate may again be increased pursuant to the preceding provisions.

   To exchange your outstanding notes for transferable new notes in the
exchange offer, you will be required to make the following representations:

  .   any new notes will be acquired in the ordinary course of your business;

  .   you have no arrangement or understanding with any person or entity to
      participate in the distribution of the new notes;

  .   you are not engaged in and do not intend to engage in the distribution of
      the new notes;

  .   if you are a broker-dealer that will receive new notes for your own
      account in exchange for outstanding notes, you acquired those notes as a
      result of market-making activities or other trading activities and you
      will deliver a prospectus, as required by law, in connection with any
      resale of such new notes; and

  .   you are not our "affiliate," as defined in Rule 405 of the Securities Act.

   In addition, we may require you to provide information to be used in
connection with the shelf registration statement to have your outstanding notes
included in the shelf registration statement. A holder who sells outstanding
notes under the shelf registration statement generally will be required to be
named as a selling securityholder in the related prospectus and to deliver a
prospectus to purchasers. Such a holder will also be subject to the civil
liability provisions under the Securities Act in connection with such sales and
will be bound by the provisions of the registration rights agreement that are
applicable to such a holder, including indemnification obligations.

   The description of the registration rights agreement contained in this
section is a summary only. For more information, you should review the
provisions of the registration rights agreement that we filed with the SEC as
an exhibit to the registration statement of which this prospectus is a part.

                                      13

<PAGE>

Resale of New Notes

   Based on no action letters of the SEC staff issued to third parties, we
believe that new notes may be offered for resale, resold and otherwise
transferred by you without further compliance with the registration and
prospectus delivery provisions of the Securities Act if:

  .   you are not our "affiliate" within the meaning of Rule 405 under the
      Securities Act;

  .   such new notes are acquired in the ordinary course of your business; and

  .   you do not intend to participate in a distribution of the new notes.

   The SEC, however, has not considered the exchange offer for the new notes in
the context of a no action letter, and the SEC may not make a similar
determination as in the no action letters issued to these third parties.

   If you tender in the exchange offer with the intention of participating in
any manner in a distribution of the new notes, you

  .   cannot rely on such interpretations by the SEC staff; and

  .   must comply with the registration and prospectus delivery requirements of
      the Securities Act in connection with a secondary resale transaction.

   Unless an exemption from registration is otherwise available, any security
holder intending to distribute new notes should be covered by an effective
registration statement under the Securities Act. The registration statement
should contain the selling security holder's information required by Item 507
of Regulation S-K under the Securities Act.

   This prospectus may be used for an offer to resell, resale or other
retransfer of new notes only as specifically described in this prospectus.
Failure to comply with the registration and prospectus delivery requirements by
a holder subject to these requirements could result in that holder incurring
liability for which it is not indemnified by us. If you are a broker-dealer,
you may participate in the exchange offer only if you acquired the outstanding
notes as a result of market-making activities or other trading activities may
participate in the exchange offer. Each broker-dealer that receives new notes
for its own account in exchange for outstanding notes, where such outstanding
notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities, must acknowledge in the letter of
transmittal that it will deliver a prospectus in connection with any resale of
the new notes. Please read the section captioned "Plan of Distribution" for
more details regarding the transfer of new notes.

Terms of the Exchange Offer

   Subject to the terms and conditions described in this prospectus and in the
letter of transmittal, we will accept for exchange any outstanding notes
properly tendered and not withdrawn prior to 5:00 p.m. New York City time on
the expiration date. We will issue new notes in principal amount equal to the
principal amount of outstanding notes surrendered under the exchange offer.
Outstanding notes may be tendered only for new notes and only in integral
multiples of $1,000.

   The exchange offer is not conditioned upon any minimum aggregate principal
amount of outstanding notes being tendered for exchange.

   As of the date of this prospectus, $200,000,000 in aggregate principal
amount of the outstanding notes are outstanding. This prospectus and the letter
of transmittal are being sent to all registered holders of outstanding notes.
There will be no fixed record date for determining registered holders of
outstanding notes entitled to participate in the exchange offer.

                                      14

<PAGE>

   We intend to conduct the exchange offer in accordance with the provisions of
the registration rights agreement, the applicable requirements of the
Securities Act and the Securities Exchange Act of 1934 and the rules and
regulations of the SEC. Outstanding notes that the holders thereof do not
tender for exchange in the exchange offer will remain outstanding and continue
to accrue interest. These outstanding notes will be entitled to the rights and
benefits such holders have under the indenture relating to the notes and the
registration rights agreement.

   We will be deemed to have accepted for exchange properly tendered
outstanding notes when we have given oral or written notice of the acceptance
to the exchange agent and complied with the applicable provisions of the
registration rights agreement. The exchange agent will act as agent for the
tendering holders for the purposes of receiving the new notes from us.

   If you tender outstanding notes in the exchange offer, you will not be
required to pay brokerage commissions or fees or, subject to the letter of
transmittal, transfer taxes with respect to the exchange of outstanding notes.
We will pay all charges and expenses, other than certain applicable taxes
described below, in connection with the exchange offer. It is important that
you read the section labeled "--Fees and Expenses" for more details regarding
fees and expenses incurred in the exchange offer.

   We will return any outstanding notes that we do not accept for exchange for
any reason without expense to their tendering holder as promptly as practicable
after the expiration or termination of the exchange offer.

Expiration Date

   The exchange offer will expire at 5:00 p.m. New York City time on         ,
2002, unless, in our sole discretion, we extend it.

Extensions, Delays in Acceptance, Termination or Amendment

   We expressly reserve the right, at any time or various times, to extend the
period of time during which the exchange offer is open. During any such
extensions, all outstanding notes previously tendered will remain subject to
the exchange offer, and we may accept them for exchange.

   In order to extend the exchange offer, we will notify the exchange agent
orally or in writing of any extension. We will notify the registered holders of
outstanding notes of the extension no later than 9:00 a.m., New York City time,
on the business day after the previously scheduled expiration date.

   If any of the conditions described below under "--Conditions to the Exchange
Offer" have not been satisfied, we reserve the right, in our sole discretion

  .   to delay accepting for exchange any outstanding notes,

  .   to extend the exchange offer, or

  .   to terminate the exchange offer,

by giving oral or written notice of such delay, extension or termination to the
exchange agent. Subject to the terms of the registration rights agreement, we
also reserve the right to amend the terms of the exchange offer in any manner.

   Any such delay in acceptance, extension, termination or amendment will be
followed as promptly as practicable by oral or written notice thereof to the
registered holders of outstanding notes. If we amend the exchange offer in a
manner that we determine to constitute a material change, we will promptly
disclose such amendment by means of a prospectus supplement. The supplement
will be distributed to the registered holders of the outstanding notes.
Depending upon the significance of the amendment and the manner of disclosure
to the

                                      15

<PAGE>

registered holders, we will extend the exchange offer if the exchange offer
would otherwise expire during such period.

Conditions to the Exchange Offer

   We will not be required to accept for exchange, or exchange any new notes
for, any outstanding notes if the exchange offer, or the making of any exchange
by a holder of outstanding notes, would violate applicable law or any
applicable interpretation of the staff of the SEC. Similarly, we may terminate
the exchange offer as provided in this prospectus before accepting outstanding
notes for exchange in the event of such a potential violation.

   In addition, we will not be obligated to accept for exchange the outstanding
notes of any holder that has not made to us the representations described under
"--Purpose and Effect of the Exchange Offer," "--Procedures for Tendering" and
"Plan of Distribution" and such other representations as may be reasonably
necessary under applicable SEC rules, regulations or interpretations to allow
us to use an appropriate form to register the new notes under the Securities
Act.

   We expressly reserve the right to amend or terminate the exchange offer, and
to reject for exchange any outstanding notes not previously accepted for
exchange, upon the occurrence of any of the conditions to the exchange offer
specified above. We will give oral or written notice of any extension,
amendment, non-acceptance or termination to the holders of the outstanding
notes as promptly as practicable.

   These conditions are for our sole benefit, and we may assert them or waive
them in whole or in part at any time or at various times in our sole
discretion. If we fail at any time to exercise any of these rights, this
failure will not mean that we have waived our rights. Each such right will be
deemed an ongoing right that we may assert at any time or at various times.

   In addition, we will not accept for exchange any outstanding notes tendered,
and will not issue new notes in exchange for any such outstanding notes, if at
such time any stop order has been threatened or is in effect with respect to
the registration statement of which this prospectus constitutes a part or the
qualification of the indenture relating to the notes under the Trust Indenture
Act of 1939.

Procedures for Tendering

  How to Tender Generally

   Only a holder of outstanding notes may tender such outstanding notes in the
exchange offer. To tender in the exchange offer, a holder must:

  .   complete, sign and date the letter of transmittal, or a facsimile of the
      letter of transmittal;

  .   have the signature on the letter of transmittal guaranteed if the letter
      of transmittal so requires; and

     .   mail or deliver such letter of transmittal or facsimile to the
         exchange agent prior to 5:00 p.m. New York City time on the expiration
         date; or

     .   comply with the automated tender offer program procedures of The
         Depository Trust Company, or DTC, described below.

   In addition, either:

  .   the exchange agent must receive outstanding notes along with the letter
      of transmittal;

  .   the exchange agent must receive, prior to 5:00 p.m. New York City time on
      the expiration date, a timely confirmation of book-entry transfer of such
      outstanding notes into the exchange agent's account at DTC according to
      the procedure for book-entry transfer described below or a properly
      transmitted agent's message; or

  .   the holder must comply with the guaranteed delivery procedures described
      below.

                                      16

<PAGE>

   To be tendered effectively, the exchange agent must receive any physical
delivery of the letter of transmittal and other required documents at its
address indicated on the cover page of the letter of transmittal. The exchange
agent must receive such documents prior to 5:00 p.m. New York City time on the
expiration date.

   The tender by a holder that is not withdrawn prior to 5:00 p.m. New York
City time on the expiration date will constitute an agreement between the
holder and us in accordance with the terms and subject to the conditions
described in this prospectus and in the letter of transmittal.

   The method of delivery of outstanding notes, the letter of transmittal and
all other required documents to the exchange agent is at your election and
risk. Rather than mail these items, we recommend that you use an overnight or
hand delivery service. In all cases, you should allow sufficient time to assure
delivery to the exchange agent before 5:00 p.m. New York City time on the
expiration date.

   You should not send the letter of transmittal or outstanding notes to us.
You may request your brokers, dealers, commercial banks, trust companies or
other nominees to effect the above transactions for you.

  How to Tender if You Are a Beneficial Owner

   If you beneficially own outstanding notes that are registered in the name of
a broker, dealer, commercial bank, trust company or other nominee and you wish
to tender those notes, you should contact the registered holder promptly and
instruct it to tender on your behalf. If you are a beneficial owner and wish to
tender on your own behalf, you must, prior to completing and executing the
letter of transmittal and delivering your outstanding notes, either:

  .   make appropriate arrangements to register ownership of the outstanding
      notes in your name; or

  .   obtain a properly completed bond power from the registered holder of
      outstanding notes.

   The transfer of registered ownership, if permitted under the indenture for
the notes, may take considerable time and may not be completed prior to the
expiration date.

  Signatures and Signature Guarantees

   You must have signatures on a letter of transmittal or a notice of
withdrawal (as described below) guaranteed by a member firm of a registered
national securities exchange or of the National Association of Securities
Dealers, Inc., a commercial bank or trust company having an office or
correspondent in the United States, or an "eligible guarantor institution"
within the meaning of Rule 17Ad-15 under the Securities Exchange Act. In
addition, such entity must be a member of one of the recognized signature
guarantee programs identified in the letter of transmittal. Signature
guarantees are not required, however, if the notes are tendered:

  .   by a registered holder who has not completed the box entitled "Special
      Issuance Instructions" or "Special Delivery Instructions" on the letter
      of transmittal;

  .   for the account of a member firm of a registered national securities
      exchange or of the National Association of Securities Dealers, Inc., a
      commercial bank or trust company having an office or correspondence in
      the United States, or an eligible guarantor institution.

  When You Need Endorsements or Bond Powers

   If the letter of transmittal is signed by a person other than the registered
holder of any outstanding notes, the outstanding notes must be endorsed or
accompanied by a properly completed bond power. The bond power must be signed
by the registered holder as the registered holder's name appears on the
outstanding notes. A member firm of a registered national securities exchange
or of the National Association of Securities Dealers, Inc., a

                                      17

<PAGE>

commercial bank or trust company having an office or correspondent in the
United States, or an eligible guarantor institution must guarantee the
signature on the bond power.

   If the letter of transmittal or any outstanding notes or bond powers are
signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, those persons should so indicate when signing. Unless waived by us,
they should also submit evidence satisfactory to us of their authority to
deliver the letter of transmittal.

  Tendering Through DTC's Automated Tender Offer Program

   The exchange agent and DTC have confirmed that any financial institution
that is a participant in DTC's system may use DTC's automated tender offer
program to tender. Participants in the program may, instead of physically
completing and signing the letter of transmittal and delivering it to the
exchange agent, transmit their acceptance of the exchange offer electronically.
They may do so by causing DTC to transfer the outstanding notes to the exchange
agent in accordance with its procedures for transfer. DTC will then send an
agent's message to the exchange agent.

   The term "agent's message" means a message transmitted by DTC, received by
the exchange agent and forming part of the book-entry confirmation, to the
effect that:

  .   DTC has received an express acknowledgment from a participant in its
      automated tender offer program that is tendering outstanding notes that
      are the subject of such book-entry confirmation;

  .   such participant has received and agrees to be bound by the terms of the
      letter of transmittal or, in the case of an agent's message relating to
      guaranteed delivery, that such participant has received and agrees to be
      bound by the applicable notice of guaranteed delivery; and

  .   the agreement may be enforced against such participant.

  Determinations Under the Exchange Offer

   We will determine in our sole discretion all questions as to the validity,
form, eligibility, time of receipt, acceptance of tendered outstanding notes
and withdrawal of tendered outstanding notes. Our determination will be final
and binding. We reserve the absolute right to reject any outstanding notes not
properly tendered or any outstanding notes our acceptance of which would, in
the opinion of our counsel, be unlawful. We also reserve the right to waive any
defect, irregularities or conditions of tender as to particular outstanding
notes. Our interpretation of the terms and conditions of the exchange offer,
including the instructions in the letter of transmittal, will be final and
binding on all parties. Unless waived, all defects or irregularities in
connection with tenders of outstanding notes must be cured within such time as
we shall determine. Although we intend to notify holders of defects or
irregularities with respect to tenders of outstanding notes, neither we, the
exchange agent nor any other person will incur any liability for failure to
give such notification. Tenders of outstanding notes will not be deemed made
until such defects or irregularities have been cured or waived. Any outstanding
notes received by the exchange agent that are not properly tendered and as to
which the defects or irregularities have not been cured or waived will be
returned to the tendering holder, unless otherwise provided in the letter of
transmittal, as soon as practicable following the expiration date.

  When We Will Issue New Notes

   In all cases, we will issue new notes for outstanding notes that we have
accepted for exchange under the exchange offer only after the exchange agent
timely receives:

  .   outstanding notes or a timely book-entry confirmation of such outstanding
      notes into the exchange agent's account at DTC; and

  .   a properly completed and duly executed letter of transmittal and all
      other required documents or a properly transmitted agent's message.

                                      18

<PAGE>

  Return of Outstanding Notes Not Accepted or Exchanged

   If we do not accept any tendered outstanding notes for exchange or if
outstanding notes are submitted for a greater principal amount than the holder
desires to exchange, the unaccepted or non-exchanged outstanding notes will be
returned without expense to their tendering holder. In the case of outstanding
notes tendered by book-entry transfer in the exchange agent's account at DTC
according to the procedures described below, such non-exchanged outstanding
notes will be credited to an account maintained with DTC. These actions will
occur as promptly as practicable after the expiration or termination of the
exchange offer.

  Your Representations to Us

   By signing or agreeing to be bound by the letter of transmittal, you will
represent to us that, among other things:

  .   any new notes that you receive will be acquired in the ordinary course of
      your business;

  .   you have no arrangement or understanding with any person or entity to
      participate in the distribution of the new notes;

  .   you are not engaged in and do not intend to engage in the distribution of
      the new notes;

  .   if you are a broker-dealer that will receive new notes for your own
      account in exchange for outstanding notes, you acquired those notes as a
      result of market-making activities or other trading activities and you
      will deliver a prospectus, as required by law, in connection with any
      resale of such new notes; and

  .   you are not our "affiliate," as defined in Rule 405 of the Securities Act.

Book-Entry Transfer

   The exchange agent will establish an account with respect to the outstanding
notes at DTC for purposes of the exchange offer promptly after the date of this
prospectus. Any financial institution participating in DTC's system may make
book-entry delivery of outstanding notes by causing DTC to transfer such
outstanding notes into the exchange agent's account at DTC in accordance with
DTC's procedures for transfer. Holders of outstanding notes who are unable to
deliver confirmation of the book-entry tender of their outstanding notes into
the exchange agent's account at DTC or all other documents required by the
letter of transmittal to the exchange agent on or prior to 5:00 p.m. New York
City time on the expiration date must tender their outstanding notes according
to the guaranteed delivery procedures described below.

Guaranteed Delivery Procedures

   If you wish to tender your outstanding notes but your outstanding notes are
not immediately available or you cannot deliver your outstanding notes, the
letter of transmittal or any other required documents to the exchange agent or
comply with the applicable procedures under DTC's automated tender offer
program prior to the expiration date, you may tender if:

  .   the tender is made through a member firm of a registered national
      securities exchange or of the National Association of Securities Dealers,
      Inc., a commercial bank or trust company having an office or
      correspondent in the United States, or an eligible guarantor institution,

  .   prior to the expiration date, the exchange agent receives from such
      member firm of a registered national securities exchange or of the
      National Association of Securities Dealers, Inc., commercial bank or
      trust company having an office or correspondent in the United States, or
      eligible guarantor institution either a properly completed and duly
      executed notice of guaranteed delivery by facsimile transmission, mail or
      hand delivery, or a properly transmitted agent's message and notice of
      guaranteed delivery, in either case:

     .   setting forth your name and address, the registered number(s) of your
         outstanding notes and the principal amount of outstanding notes
         tendered,

                                      19

<PAGE>

     .   stating that the tender is being made thereby, and

     .   guaranteeing that, within three (3) New York Stock Exchange ("NYSE")
         trading days after the expiration date, the letter of transmittal or
         facsimile thereof, together with the outstanding notes or a book-entry
         confirmation, and any other documents required by the letter of
         transmittal will be deposited by the eligible guarantor institution
         with the exchange agent, and

     .   the exchange agent receives such properly completed and executed
         letter of transmittal or facsimile thereof, as well as all tendered
         outstanding notes in proper form for transfer or a book-entry
         confirmation, and all other documents required by the letter of
         transmittal, within three (3) NYSE trading days after the expiration
         date.

   Upon request to the exchange agent, a notice of guaranteed delivery will be
sent you if you wish to tender your outstanding notes according to the
guaranteed delivery procedures described above.

Withdrawal of Tenders

   Except as otherwise provided in this prospectus, you may withdraw your
tender at any time prior to 5:00 p.m. New York City time on the expiration date.

   For a withdrawal to be effective:

  .   the exchange agent must receive a written notice of withdrawal at the
      address indicated on the cover page of the letter of transmittal or

  .   you must comply with the appropriate procedures of DTC's automated tender
      offer program system.

   Any notice of withdrawal must:

  .   specify the name of the person who tendered the outstanding notes to be
      withdrawn, and

  .   identify the outstanding notes to be withdrawn, including the principal
      amount of such outstanding notes.

   If outstanding notes have been tendered under the procedure for book-entry
transfer described above, any notice of withdrawal must specify the name and
number of the account at DTC to be credited with withdrawn outstanding notes
and otherwise comply with the procedures of DTC.

   We will determine all questions as to the validity, form, eligibility and
time of receipt of notice of withdrawal. Our determination shall be final and
binding on all parties. We will deem any outstanding notes so withdrawn not to
have been validly tendered for exchange for purposes of the exchange offer.

   Any outstanding notes that have been tendered for exchange but that are not
exchanged for any reason will be returned to their holder without cost to the
holder. In the case of outstanding notes tendered by book-entry transfer into
the exchange agent's account at DTC according to the procedures described
above, such outstanding notes will be credited to an account maintained with
DTC for the outstanding notes. This return or crediting will take place as soon
as practicable after withdrawal, rejection of tender or termination of the
exchange offer. You may retender properly withdrawn outstanding notes by
following one of the procedures described under "--Procedures for Tendering"
above at any time on or prior to the expiration date.

                                      20

Fees and Expenses

   We will bear the expenses of soliciting tenders. The principal solicitation
is being made by mail; however, we may make additional solicitation by
telegraph, telephone or in person by our officers and regular employees and
those of our affiliates.

   We have not retained any dealer-manager in connection with the exchange
offer and will not make any payments to broker-dealers or others soliciting
acceptances of the exchange offer. We will, however, pay the exchange agent
reasonable and customary fees for its services and reimburse it for its related
reasonable out-of-pocket expenses.

   We will pay the cash expenses to be incurred in connection with the exchange
offer. They include:

  .   SEC registration fees;

  .   fees and expenses of the exchange agent and trustee;

  .   accounting and legal fees and printing costs; and

  .   related fees and expenses.

Transfer Taxes

   We will pay all transfer taxes, if any, applicable to the exchange of
outstanding notes under the exchange offer. The tendering holder, however, will
be required to pay any transfer taxes, whether imposed on the registered holder
or any other person, if:

  .   certificates representing outstanding notes for principal amounts not
      tendered or accepted for exchange are to be delivered to, or are to be
      issued in the name of, any person other than the registered holder of
      outstanding notes tendered;

  .   tendered outstanding notes are registered in the name of any person other
      than the person signing the letter of transmittal; or

  .   a transfer tax is imposed for any reason other than the exchange of
      outstanding notes under the exchange offer.

   If satisfactory evidence of payment of any transfer taxes payable by a note
holder is not submitted with the letter of transmittal, the amount of such
transfer taxes will be billed directly to that tendering holder.

Consequences of Failure to Exchange

   If you do not exchange new notes for your outstanding notes under the
exchange offer, you will remain subject to the existing restrictions on
transfer of the outstanding notes. In general, you may not offer or sell the
outstanding notes unless they are registered under the Securities Act, or if
the offer or sale is exempt from the registration under the Securities Act and
applicable state securities laws. Except as required by the registration rights
agreement, we do not intend to register resales of the outstanding notes under
the Securities Act.

Accounting Treatment

   We will record the new notes in our accounting records at the same carrying
value as the outstanding notes. This carrying value is the aggregate principal
amount of the outstanding notes less any bond discount, as reflected in our
accounting records on the date of exchange. Accordingly, we will not recognize
any gain or loss for accounting purposes in connection with the exchange offer.

                                      21

<PAGE>

Other

   Participation in the exchange offer is voluntary, and you should carefully
consider whether to accept. You are urged to consult your financial and tax
advisors in making your own decision on what action to take.

   We may in the future seek to acquire untendered outstanding notes in open
market or privately negotiated transactions, through subsequent exchange offers
or otherwise. We have no present plans to acquire any outstanding notes that
are not tendered in the exchange offer or to file a registration statement to
permit resales of any untendered outstanding notes.

                                USE OF PROCEEDS

   The exchange offer is intended to satisfy our obligations under the
registration rights agreement. We will not receive any cash proceeds from the
issuance of the new notes in the exchange offer. In consideration for issuing
the new notes as contemplated by this prospectus, we will receive outstanding
notes in a like principal amount. The form and terms of the new notes are
identical in all respects to the form and terms of the outstanding notes,
except the new notes do not include certain transfer restrictions. Outstanding
notes surrendered in exchange for the new notes will be retired and cancelled
and will not be reissued. Accordingly, the issuance of the new notes will not
result in any change in our outstanding indebtedness.

                                      23

<PAGE>

                         DESCRIPTION OF THE NEW NOTES

   You can find the definitions of certain terms used in this description under
the subheading "--Definitions." In this description, the word "Issuers" refers
only to Plains All American Pipeline and PAA Finance Corp. and not to any of
their subsidiaries and any reference to "Plains All American Pipeline" or "PAA
Finance Corp." does not include any of their respective subsidiaries. As used
in this section, "PAA Finance Corp." means our corporate subsidiary, PAA
Finance Corp., which is a co-issuer of the notes. References to "notes" in this
section of the prospectus include both the outstanding notes and the new notes.

   The Issuers will issue the new notes, and the outstanding notes were issued,
under an Indenture (the "Indenture") among the Issuers, the Subsidiary
Guarantors and Wachovia Bank, National Association, as trustee (the "Trustee").
The terms of the notes include those stated in the Indenture and those made
part of the Indenture by reference to the Trust Indenture Act of 1939 (the
"Trust Indenture Act").

   The following description is a summary of the material provisions of the
Indenture. It does not restate that agreement in its entirety. We urge you to
read the Indenture because it, and not this description, defines your rights as
a holder of these notes. Copies of the Indenture are available upon request
from Plains All American Pipeline.

   If the exchange offer contemplated by this prospectus is consummated,
holders of outstanding notes who do not exchange those notes for new notes in
the exchange offer will vote together with holders of new notes for all
relevant purposes under the Indenture. In that regard, the Indenture requires
that certain actions by the holders thereunder (including acceleration
following an Event of Default) must be taken, and certain rights must be
exercised, by specified minimum percentages of the aggregate principal amount
of the outstanding securities issued under the Indenture. In determining
whether holders of the requisite percentage in principal amount have given any
notice, consent or waiver or taken any other action permitted under the
Indenture, any outstanding notes that remain outstanding after the exchange
offer will be aggregated with the new notes, and the holders of such
outstanding notes and the new notes will vote together as a single series for
all such purposes. Accordingly, all references herein to specified percentages
in aggregate principal amount of the notes outstanding shall be deemed to mean,
at any time after the exchange offer is consummated, such percentages in
aggregate principal amount of the outstanding notes and the new notes then
outstanding.

Brief Description of the Notes and the Guarantees

  The Notes

   The notes are:

  .   general unsecured obligations of the Issuers;

  .   equal in right of payment to any existing and future Senior Debt of the
      Issuers; and

  .   unconditionally guaranteed by the Subsidiary Guarantors.

  The Guarantees

   Initially the Issuers' obligations under the notes were jointly and
severally guaranteed by all existing subsidiaries of Plains All American
Pipeline (other than PAA Finance Corp. and 3794865 Canada Ltd.).

   Each Guarantee of a Subsidiary Guarantor of these notes is:

  .   a general unsecured obligation of that Subsidiary Guarantor; and

  .   equal in right of payment to any existing and future Senior Debt of that
      Subsidiary Guarantor.

   As of the date of the Indenture, all of our Subsidiaries were "Restricted
Subsidiaries." Also, under the circumstances described below under the
subheading "--Covenants--Designation of Restricted and Unrestricted

                                      24

<PAGE>

Subsidiaries," we will be permitted to designate certain of our Subsidiaries as
"Unrestricted Subsidiaries." Except in limited circumstances specifically
described in the Indenture, Unrestricted Subsidiaries will not be subject to
the restrictive covenants in the Indenture. Unrestricted Subsidiaries will not
guarantee the notes.

   In addition, Plains All American Pipeline has invested, and may invest in
the future, in Joint Ventures. The rights of Plains All American Pipeline to
receive assets from any Subsidiary that is not a Subsidiary Guarantor or from
any Joint Venture that are attributable to Plains All American Pipeline's
Equity Interests therein (and thus the ability of the holders of the notes to
benefit indirectly from such assets) are structurally subordinated to the
claims of all existing and future third-party indebtedness and liabilities
(including trade debt) of such Subsidiary or Joint Venture.

Principal, Maturity and Interest

   The Issuers issued the outstanding notes in an initial aggregate principal
amount of $200.0 million. Subject to compliance with the first paragraph of the
covenant described below under "--Covenants--Incurrence of Indebtedness and
Issuance of Disqualified Equity," we may issue an unlimited amount of
additional notes from time to time under the Indenture. The Issuers will issue
the new notes, and the outstanding notes were issued, in denominations of
$1,000 and integral multiples of $1,000. The notes will mature on October 15,
2012.

   Interest on the notes will accrue at the rate of 7 3/4% per annum and will be
payable semiannually in arrears on April 15 and October 15, commencing on April
15, 2003. Additional interest ("Additional Interest") may also accrue on the
notes in the circumstances described under "Exchange Offer; Registration
Rights," and all references to "interest" in this description include any such
Additional Interest. The Issuers will make each interest payment to the holders
of record of the notes on the immediately preceding April 1 and October 1.

   Interest on the new notes will accrue from the date of original issuance of
the outstanding notes or, if interest has already been paid, from the date it
was most recently paid. Interest will be computed on the basis of a 360-day
year comprised of twelve 30-day months.

Methods of Receiving Payments on the Notes

   If a holder has given wire transfer instructions to the Issuers, the Issuers
will make all payments of principal of, premium, if any, and interest and
Additional Interest, if any, on the notes in accordance with those
instructions. All other payments on the notes will be made at the corporate
trust office of the Trustee, unless the Issuers elect to make interest payments
by check mailed to the holders at their addresses set forth in the register of
holders.

Paying Agent and Registrar for the Notes

   The Trustee will initially act as paying agent and registrar. The Issuers
may change the paying agent or registrar without prior notice to the holders of
the notes, and the Issuers or any of their Subsidiaries may act as paying agent
or registrar.

Transfer and Exchange

   A holder may transfer or exchange notes in accordance with the Indenture.
The Registrar and the Trustee may require a holder, among other things, to
furnish appropriate endorsements and transfer documents and the Issuers may
require a holder to pay any taxes or other governmental charges required by law
or permitted by the Indenture. The Issuers are not required to register the
transfer of or exchange any note selected for redemption or repurchase (except,
in the case of a note to be redeemed or repurchased in part, the portion not to
be redeemed or repurchased). Also, the Issuers are not required to register the
transfer of or exchange any note for a period of 15 days before a selection of
notes to be redeemed or repurchased or during the period between a record date
and the next succeeding interest payment date.

                                      25

   The registered holder of a note will be treated as the owner of it for all
purposes.

The Guarantees

   Initially, all of the Restricted Subsidiaries of Plains All American
Pipeline (other than PAA Finance Corp. and 3794865 Canada Ltd.) were Subsidiary
Guarantors and guarantee our Obligations under the notes. The guarantees are
joint and several obligations of the Subsidiary Guarantors. In the future, the
Restricted Subsidiaries of Plains All American Pipeline will be required to
guarantee our Obligations under the notes and the Indenture under the
circumstances described under "Covenants--Additional Subsidiary Guarantees."

   The obligations of each Subsidiary Guarantor under its Guarantee will be
limited as necessary to prevent that Guarantee from constituting a fraudulent
conveyance under applicable law. See "Risk Factors--Risks Related to the Notes."

   A Subsidiary Guarantor may not consolidate with or merge with or into
(whether or not such Subsidiary Guarantor is the surviving Person) another
Person, unless:

      (1)  immediately after giving effect to that transaction, no Default or
   Event of Default exists; and

      (2)  the Person (if not otherwise a Subsidiary Guarantor) formed by or
   surviving any such consolidation or merger assumes all the obligations of
   that Subsidiary Guarantor pursuant to a supplemental Indenture in form
   satisfactory to the Trustee, except as provided in the next paragraph.

   Any Subsidiary Guarantor, however, may be merged or consolidated with or
into any one or more Subsidiary Guarantors or Plains All American Pipeline.

   The Guarantee of a Subsidiary Guarantor will be released:

      (1)  in connection with any sale or other disposition of all or
   substantially all of the assets of that Subsidiary Guarantor (including by
   way of merger, consolidation or otherwise), if Plains All American Pipeline
   applies the Net Proceeds of that sale or other disposition in accordance
   with the applicable provisions of the Indenture relating to Asset Sales; or

      (2)  in connection with any sale or other disposition of all of the
   Equity Interests of a Subsidiary Guarantor, if Plains All American Pipeline
   applies the Net Proceeds of that sale in accordance with the applicable
   provisions of the Indenture relating to Asset Sales; or

      (3)  if Plains All American Pipeline designates any Restricted Subsidiary
   that is a Subsidiary Guarantor as an Unrestricted Subsidiary; or

      (4)  at such time as such Subsidiary Guarantor ceases to guarantee any
   other Indebtedness of the Issuers or any Restricted Subsidiary of Plains All
   American Pipeline and has no Indebtedness then outstanding (other than
   Permitted Debt described in clause (6), (7), (9), (10) or (11) of the
   definition thereof).

See "--Repurchase at the Option of Holders--Asset Sales."

Optional Redemption

   The Issuers may choose to redeem the notes at any time. If they do so, they
may redeem all or any portion of the notes, at once or over time, after giving
the required notice under the Indenture.

   To redeem the notes, the Issuers must pay a redemption price equal to 100%
of the principal amount of the notes to be redeemed plus the Applicable Premium
as of, and accrued and unpaid interest, if any, and Additional Interest, if
any, to the redemption date (subject to the right of holders of record on the
relevant record date to receive interest due on the relevant interest payment
date). Any notice to holders of notes of such a redemption is

                                      26

<PAGE>

required to include the appropriate calculation of the redemption price, but
need not include the redemption price itself. The actual redemption price must
be set forth in an Officers' Certificate delivered to the Trustee no later than
two business days prior to the redemption date.

   "Applicable Premium" means, with respect to any note on any redemption date,
the greater of (1) 1.0% of the principal amount of the note and (2) the excess
of (a) the present value at such time of the principal amount of such note plus
any required interest payments due on such note from the redemption date to
October 15, 2012 (excluding accrued but unpaid interest), computed using a
discount rate equal to the Treasury Rate on such redemption date plus 50 basis
points over (b) the principal amount of the note.

   "Treasury Rate" means, as of any redemption date, the yield to maturity as
of such redemption date of United States Treasury securities with a constant
maturity (as compiled and published in the most recent Federal Reserve
Statistical Release H.15 (519) that has become publicly available at least two
business days prior to the redemption date (or, if such statistical release is
no longer published, any publicly available source of similar market data))
most nearly equal to the period from the redemption date to October 15, 2012;
provided, however, that if the period from the redemption date to October 15,
2012 is less than one year, the weekly average yield on actually traded United
States Treasury securities adjusted to a constant maturity of one year shall be
used.

   Except as set forth above, the notes will not be redeemable by the Issuers
prior to maturity and will not be entitled to the benefit of any sinking fund.
However, under certain circumstances, we may be required to offer to purchase
the notes as described under the subheadings "--Repurchase at the Option of
Holders--Change of Control" and "--Asset Sales."

Selection and Notice

   If less than all of the notes are to be redeemed at any time, the Trustee
will select notes for redemption as follows:

      (1)  if the notes are listed, in compliance with the requirements of the
   principal national securities exchange on which the notes are listed; or

      (2)  if the notes are not so listed or there are no such requirements, on
   a pro rata basis, by lot or by such method as the Trustee shall deem fair
   and appropriate.

   No notes of $1,000 or less shall be redeemed in part. Notices of redemption
shall be mailed at least 30 but not more than 60 days before the redemption
date to each holder of notes to be redeemed at its registered address. The
notice of redemption for the notes will state, among other things, the amount
of notes to be redeemed, the redemption date, the redemption price (or its
calculation) and the place(s) that payment will be made upon presentation and
surrender of notes to be redeemed. Notices of redemption may not be conditional.

   If any note is to be redeemed in part only, the notice of redemption that
relates to that note shall state the portion of the principal amount thereof to
be redeemed. A new note in principal amount equal to the unredeemed portion of
the original note will be issued in the name of the holder thereof upon
cancellation of the original note. Notes called for redemption become due on
the date fixed for redemption. On and after the redemption date, interest and
Additional Interest, if applicable, cease to accrue on notes or portions of
them called for redemption unless the Issuers default in making such redemption
payment.

Repurchase at the Option of Holders

  Change of Control

   If a Change of Control occurs, the Issuers will make an offer to repurchase
all or any part (equal to $1,000 or an integral multiple thereof) of the notes
pursuant to the offer described below (the "Change of Control Offer"). In the
Change of Control Offer, the Issuers will offer a Change of Control Payment
(the "Change of

                                      27

<PAGE>

Control Payment") in cash equal to 101% of the aggregate principal amount of
notes repurchased plus accrued and unpaid interest thereon and Additional
Interest, if any, to the date of purchase (the "Change of Control Payment
Date"), subject to the rights of each holder in whose name a note is registered
on a record date occurring prior to the Change of Control Payment Date to
receive interest on an interest payment date occurring after such Change of
Control Payment Date. Within 30 days following any Change of Control, the
Issuers will mail a notice to each holder describing the transaction or
transactions that constitute the Change of Control and offering to repurchase
notes on the Change of Control Payment Date specified in such notice, pursuant
to the procedures required by the Indenture and described in such notice.

   On the Change of Control Payment Date, the Issuers will, to the extent
lawful:

      (1)  accept for payment all notes or portions thereof properly tendered
   pursuant to the Change of Control Offer;

      (2)  deposit with the paying agent an amount equal to the Change of
   Control Payment in respect of all notes or portions thereof so tendered; and

      (3)  deliver or cause to be delivered to the Trustee the notes so
   accepted together with an Officers' Certificate stating the aggregate
   principal amount of notes or portions thereof being purchased by the Issuers.

   The paying agent will promptly mail to each holder of notes so tendered the
Change of Control Payment for such notes, and the Trustee will promptly
authenticate and mail (or cause to be transferred by book entry) to each holder
a new note equal in principal amount to any unpurchased portion of the notes
surrendered, if any; provided that each such new note will be in a principal
amount of $1,000 or an integral multiple thereof. The Issuers will publicly
announce the results of the Change of Control Offer on or as soon as
practicable after the Change of Control Payment Date.

   The provisions described above that require the Issuers to make a Change of
Control Offer following a Change of Control will be applicable regardless of
whether or not any other provisions of the Indenture are applicable. Except as
described above with respect to a Change of Control, the Indenture does not
contain provisions that permit holders of the notes to require that the Issuers
repurchase or redeem the notes in the event of a takeover, recapitalization or
similar transaction.

   The Partnership Credit Facilities currently provide that certain change of
control events with respect to Plains All American Pipeline would constitute a
default thereunder. Any future credit agreements to which Plains All American
Pipeline or any of its Subsidiaries becomes a party may contain similar
restrictions and provisions. Moreover, the exercise by the holders of their
right to require the Issuers to repurchase the notes could cause a default
under the Credit Facilities, even if the Change of Control does not, due to the
financial effect of such a repurchase on Plains All American Pipeline. If a
Change of Control occurs at a time when Plains All American Pipeline is
prohibited from purchasing notes or a default under the Credit Facilities would
result therefrom, Plains All American Pipeline could seek the consent to the
purchase of notes or could attempt to refinance the borrowings that contain
such prohibition. If Plains All American Pipeline does not obtain such a
consent or repay such borrowings, Plains All American Pipeline will remain
prohibited from purchasing notes. In such case, Plains All American Pipeline's
failure to purchase tendered notes would constitute an Event of Default under
the Indenture which would, in turn, in all likelihood constitute a default
under the Credit Facilities. Finally, the Issuers' ability to pay cash to the
holders upon a repurchase may be limited by Plains All American Pipeline's and
its Subsidiaries' then existing financial resources. We cannot assure you that
sufficient funds will be available when necessary to make any required
repurchases.

   Notwithstanding the preceding paragraphs of this covenant, the Issuers will
not be required to make a Change of Control Offer upon a Change of Control if a
third party makes an offer to purchase the notes in the manner, at the times
and otherwise in compliance with the requirements set forth in the Indenture
applicable to a

                                      28

<PAGE>

Change of Control Offer and purchases all notes validly tendered and not
withdrawn under such Change of Control Offer.

   "Change of Control" means the occurrence of any of the following:

      (1)  the sale, transfer, lease, conveyance or other disposition (other
   than by way of merger or consolidation), in one or a series of related
   transactions, of all or substantially all of the assets of Plains All
   American Pipeline and its Restricted Subsidiaries taken as a whole to any
   "person" (as such term is used in Section 13(d)(3) of the Exchange Act),
   which occurrence is followed by a Rating Decline within 90 days of the
   consummation of such transaction;

      (2)  the adoption of a plan relating to the liquidation or dissolution of
   Plains All American Pipeline, or the removal of the General Partner by the
   limited partners of Plains All American Pipeline;

      (3)  such time as Qualifying Directors cease for any reason to constitute
   collectively a majority of the members of the Board of Directors of the
   Managing General Partner in office, which occurrence is followed by a Rating
   Decline within 90 days thereof; or

      (4)  any "person" or "group," as such terms are used in Sections 13(d)(2)
   and 14(d)(2) of the Exchange Act, excluding the Qualifying Owners identified
   in clause (i) of the definition of Qualifying Owners, obtains the right to
   appoint a majority of the Board of Directors, which occurrence is followed
   by a Rating Decline within 90 days thereof.

   Notwithstanding the preceding, a conversion of Plains All American Pipeline
or any of its Restricted Subsidiaries from a limited partnership, corporation,
limited liability company or other form of entity to a limited partnership,
corporation, limited liability company or other form of entity or an exchange
of all of the outstanding Equity Interests in one form of entity for Equity
Interests for another form of entity shall not constitute a Change of Control,
so long as following such conversion or exchange the Qualifying Owners
beneficially own, directly or indirectly, in the aggregate more than 50% of the
Voting Stock of such entity, or continue to beneficially own sufficient Equity
Interests in such entity to elect a majority of its directors, managers,
trustees or other persons serving in a similar capacity for such entity.

   The definition of Change of Control includes a phrase relating to the sale,
transfer, lease, conveyance or other disposition of "all or substantially all"
of the assets of Plains All American Pipeline and its Restricted Subsidiaries,
taken as a whole. Although there is a limited body of case law interpreting the
phrase "all or substantially all" of a company's assets, there is no precise
established definition of the phrase under applicable law. Accordingly, the
ability of a holder of notes to require Plains All American Pipeline to
repurchase such notes as a result of a sale, transfer, lease, conveyance or
other disposition of less than all of the assets of Plains All American
Pipeline and its Restricted Subsidiaries taken as a whole to another person or
group may be uncertain.

  Asset Sales

   The Issuers will not, and will not permit their Restricted Subsidiaries to,
consummate an Asset Sale unless:

      (1)  Plains All American Pipeline (or the Restricted Subsidiary, as the
   case may be) receives consideration at the time of such Asset Sale at least
   equal to the fair market value of the assets or Equity Interests issued or
   sold or otherwise disposed of;

      (2)  such fair market value is determined by (a) an executive officer of
   the Managing General Partner if the value is less than $10.0 million, as
   evidenced by an Officers' Certificate delivered to the Trustee, or (b) the
   Board of Directors if the value is $10.0 million or more, as evidenced by a
   resolution of such Board of Directors; and

      (3)  at least 75% of the consideration therefor received by Plains All
   American Pipeline or such Restricted Subsidiary is in the form of (a) cash
   or Cash Equivalents, (b) assets or rights used or useful in a

                                      29

<PAGE>

   Permitted Business or (c) any Permitted Business Investment or any other
   Permitted Investment other than Hedging Obligations. For purposes of this
   provision, each of the following shall be deemed to be cash:

          (x)  any liabilities (as shown on Plains All American Pipeline's or
       such Restricted Subsidiary's most recent balance sheet) of Plains All
       American Pipeline or any Restricted Subsidiary (other than contingent
       liabilities and liabilities that are by their terms subordinated to the
       notes or any Guarantee) that are assumed by the transferee of any such
       assets pursuant to a customary novation agreement that releases Plains
       All American Pipeline or such Restricted Subsidiary from further
       liability; and

          (y)  any securities, notes or other obligations received by Plains
       All American Pipeline or any such Restricted Subsidiary from such
       transferee that are within 90 days after the Asset Sale (subject to
       ordinary settlement periods) converted by Plains All American Pipeline
       or such Restricted Subsidiary into cash (to the extent of the cash
       received in that conversion).

   Within 360 days after the receipt of any Net Proceeds from an Asset Sale,
Plains All American Pipeline or a Restricted Subsidiary may apply (or enter
into a definitive agreement for such application within such 360-day period,
provided that such capital expenditure or acquisition is closed within 90 days
after the end of such 360-day period) such Net Proceeds at its option:

      (1)  to repay Senior Debt of Plains All American Pipeline and/or its
   Restricted Subsidiaries (or to make an offer to repurchase or redeem Senior
   Debt, provided that such repurchase or redemption closes within 45 days
   after the end of such 360-day period) with a permanent reduction in
   availability for any Credit Facilities pursuant to clause (1) of the
   definition of Permitted Debt;

      (2)  to make a capital expenditure in a Permitted Business;

      (3)  to acquire other assets or rights that are used or useful in a
   Permitted Business; or

      (4)  to invest in any other Permitted Business Investment or any other
   Permitted Investment other than Investments in Cash Equivalents or Hedging
   Obligations.

   Pending the final application of any such Net Proceeds, we may temporarily
reduce revolving credit borrowings or otherwise invest such Net Proceeds in any
manner that is not prohibited by the Indenture and we will reserve the amount
of such Net Proceeds, other than those temporarily applied, in calculating our
Available Cash.

   Any Net Proceeds from Asset Sales that are not applied or invested as
provided in the preceding paragraph will constitute "Excess Proceeds." When the
aggregate amount of Excess Proceeds exceeds $10.0 million, the Issuers will
make a pro rata offer (an "Asset Sale Offer") to all holders of notes and all
holders of other Indebtedness that is pari passu with the notes containing
provisions similar to those set forth in the Indenture with respect to offers
to purchase or redeem with the proceeds of sales of assets to purchase the
maximum principal amount of notes and such other pari passu Indebtedness that
may be purchased out of the Excess Proceeds. The offer price in any Asset Sale
Offer will be equal to 100% of principal amount plus accrued and unpaid
interest (including any Additional Interest in the case of the notes), if any,
and premium, if any, to the date of purchase, and will be payable in cash. If
any Excess Proceeds remain after consummation of an Asset Sale Offer, such
Excess Proceeds shall be deemed to constitute Available Cash from Operating
Surplus for purposes of the Indenture, and Plains All American Pipeline may use
such Excess Proceeds for any purpose not otherwise prohibited by the Indenture.
If the aggregate principal amount of notes tendered into such Asset Sale Offer
exceeds the amount of Excess Proceeds allocated for repurchases of notes
pursuant to the Asset Sale Offer for notes, the Trustee shall select the notes
to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer,
the amount of Excess Proceeds shall be reset at zero.

  Compliance with Securities Laws

   The Issuers will comply with the requirements of Rule 14e-1 under the
Exchange Act and any other securities laws and regulations thereunder to the
extent such laws and regulations are applicable to the purchase

                                      30

<PAGE>

of the notes in a Change of Control Offer or Asset Sale Offer. To the extent
that the provisions of any securities laws or regulations conflict with the
Change of Control or Asset Sale provisions of the Indenture, the Issuers will
comply with the applicable securities laws and regulations and will not be
deemed to have committed a breach of their obligations under the Change of
Control or Asset Sale provisions of the Indenture by virtue of such conflict.

Covenants

  Restricted Payments

   Plains All American Pipeline will not, and will not permit any of its
Restricted Subsidiaries to, directly or indirectly:

      (1)  declare or pay any dividend or make any other payment or
   distribution on account of Plains All American Pipeline's or any of its
   Restricted Subsidiaries' Equity Interests (including, without limitation,
   any payment in connection with any merger or consolidation involving Plains
   All American Pipeline or any of its Restricted Subsidiaries) or to the
   direct or indirect holders of Plains All American Pipeline's or any of its
   Restricted Subsidiaries' Equity Interests in their capacity as such (other
   than distributions or dividends payable in Equity Interests of Plains All
   American Pipeline (other than Disqualified Equity) and other than
   distributions or dividends payable to Plains All American Pipeline or any of
   its wholly owned Restricted Subsidiaries);

      (2)  except to the extent permitted in clause (4) below, purchase, redeem
   or otherwise acquire or retire for value (including, without limitation, in
   connection with any merger or consolidation involving an Issuer) any Equity
   Interests of Plains All American Pipeline or any of its Restricted
   Subsidiaries (other than any such Equity Interests owned by Plains All
   American Pipeline or any of its wholly owned Restricted Subsidiaries);

      (3)  except to the extent permitted in clause (4) below, make any payment
   on or with respect to, or purchase, redeem, defease or otherwise acquire or
   retire for value any Indebtedness of Plains All American Pipeline or any
   Restricted Subsidiary that is subordinated by its terms to the notes or the
   Guarantees except (a) a payment of interest or principal at the Stated
   Maturity thereof or (b) a purchase, redemption, acquisition or retirement
   required to be made pursuant to the terms of such Indebtedness (including
   pursuant to an asset sale or change of control provision); or

      (4)  make any Investment other than a Permitted Investment or a Permitted
   Business Investment

(all such payments and other actions set forth in clauses (1) through (4) above
being collectively referred to as "Restricted Payments"), unless, at the time
of and after giving effect to such Restricted Payment, no Default or Event of
Default shall have occurred and be continuing or would occur as a consequence
thereof and either:

      (1)  if the Fixed Charge Coverage Ratio for Plains All American
   Pipeline's four most recent fiscal quarters for which internal financial
   statements are available is not less than 1.75 to 1.0, such Restricted
   Payment, together with the aggregate amount of all other Restricted Payments
   made by Plains All American Pipeline and its Restricted Subsidiaries with
   respect to the quarter for which such Restricted Payment is made, is less
   than the sum, without duplication, of:

          (a)  Available Cash from Operating Surplus with respect to the
       immediately preceding quarter, plus

          (b)  the sum of the aggregate net cash proceeds and the fair market
       value of any assets or rights used or useful in a Permitted Business
       received by Plains All American Pipeline or any of its Restricted
       Subsidiaries in connection with (A) a capital contribution to Plains All
       American Pipeline from any Person (other than a Restricted Subsidiary of
       Plains All American Pipeline) made after the Issue Date or a capital
       contribution to a Restricted Subsidiary from any Person (other than
       Plains All American Pipeline or another Restricted Subsidiary) made
       after the Issue Date or (B) an issuance and sale made after the Issue
       Date of Equity Interests (other than Disqualified Equity) of Plains All
       American Pipeline

                                      31

<PAGE>

       or from the issuance or sale made after the Issue Date of convertible or
       exchangeable Disqualified Equity or convertible or exchangeable debt
       securities of Plains All American Pipeline that have been converted into
       or exchanged for such Equity Interests (other than Disqualified Equity),
       plus

          (c)  to the extent that any Restricted Investment that was made after
       the Issue Date is sold for cash or Cash Equivalents or otherwise
       liquidated or repaid for cash or Cash Equivalents, the lesser of the
       refund of capital or similar payment made in cash or Cash Equivalents
       with respect to such Restricted Investment (less the cost of such
       disposition, if any) and the initial amount of such Restricted
       Investment (other than to a Restricted Subsidiary of Plains All American
       Pipeline), plus

          (d)  the net reduction in Restricted Investments resulting from
       dividends, repayments of loans or advances, or other transfers of assets
       in each case to Plains All American Pipeline or any of its Restricted
       Subsidiaries from any Person (including, without limitation,
       Unrestricted Subsidiaries) or from redesignations of Unrestricted
       Subsidiaries as Restricted Subsidiaries, to the extent such amounts have
       not been included in Available Cash from Operating Surplus for any
       period commencing on or after the Issue Date (items (b), (c) and (d)
       being referred to as "Incremental Funds"), minus

          (e)  the aggregate amount of Incremental Funds previously expended
       pursuant to this clause (1) and clause (2) below; or

      (2)  if the Fixed Charge Coverage Ratio for Plains All American
   Pipeline's four most recent fiscal quarters for which internal financial
   statements are available is less than 1.75 to 1.00, such Restricted Payment,
   together with the aggregate amount of all other Restricted Payments made by
   Plains All American Pipeline and its Restricted Subsidiaries with respect to
   the quarter for which such Restricted Payment is made (such Restricted
   Payments for purposes of this clause (2) meaning only distributions on
   common units of Plains All American Pipeline, plus the related distribution
   on the general partner interest), is less than the sum, without duplication,
   of:

          (a)  $75.0 million less the aggregate amount of all Restricted
       Payments made by Plains All American Pipeline and its Restricted
       Subsidiaries pursuant to this clause (2)(a) during the period ending on
       the last day of the fiscal quarter of Plains All American Pipeline
       immediately preceding the date of such Restricted Payment and beginning
       on the Issue Date, plus

          (b)  Incremental Funds to the extent not previously expended pursuant
       to this clause (2) or clause (1) above.

   So long as no Default has occurred and is continuing or would be caused
thereby (except with respect to clause (1) below under which the payment of a
distribution or dividend is permitted), the preceding provisions will not
prohibit:

      (1)  the payment by Plains All American Pipeline or any Restricted
   Subsidiary of any distribution or dividend within 60 days after the date of
   declaration thereof, if at said date of declaration such payment would have
   complied with the provisions of the Indenture;

      (2)  the redemption, repurchase, retirement, defeasance or other
   acquisition of any Indebtedness of Plains All American Pipeline or any of
   its Restricted Subsidiaries that is subordinated to the notes or the
   Guarantees or of any Equity Interests of Plains All American Pipeline or any
   of its Restricted Subsidiaries in exchange for, or out of the net cash
   proceeds of, a substantially concurrent (a) capital contribution to Plains
   All American Pipeline or such Restricted Subsidiary from any Person (other
   than Plains All American Pipeline or another Restricted Subsidiary) or (b)
   sale (a sale will be deemed substantially concurrent if such redemption,
   repurchase, retirement, defeasance or acquisition occurs not more than 120
   days after such sale) (other than to a Restricted Subsidiary of Plains All
   American Pipeline) of Equity Interests (other than Disqualified Equity) of
   Plains All American Pipeline or such Restricted Subsidiary; provided,
   however, that the amount of any net cash proceeds that are utilized for any
   such redemption, repurchase or other acquisition or retirement shall be
   excluded or deducted from the calculation of Available Cash from Operating
   Surplus and Incremental Funds;

                                      32

<PAGE>

      (3)  the defeasance, redemption, repurchase or other acquisition of
   Indebtedness of Plains All American Pipeline or any Restricted Subsidiary
   that is subordinated to the notes or the Guarantees with the net cash
   proceeds from an incurrence of Permitted Refinancing Indebtedness;

      (4)  the payment of any distribution or dividend by a Restricted
   Subsidiary to Plains All American Pipeline or to the holders of its Equity
   Interests (other than Disqualified Equity) on a pro rata basis;

      (5)  the purchase or other acquisition of one or more Equity Interests in
   Plains All American Pipeline from former employees of Plains All American
   Pipeline; provided, that the aggregate price paid for all such purchased or
   acquired Equity Interests shall not exceed $2.0 million in any 12-month
   period;

      (6)  the repurchase, redemption or other acquisition or retirement for
   value of any Equity Interests to satisfy awards under the General Partner's
   1998 Long-Term Incentive Plan, as amended, provided such repurchases do not
   exceed an aggregate of 1,425,000 common units (as such number may be
   adjusted for any subdivision or combination of common units) after the issue
   date of the notes; and

      (7)  the repurchase, redemption or other acquisition or retirement for
   value of any Equity Interests of Plains All American Pipeline or any
   Restricted Subsidiary of Plains All American Pipeline pursuant to any
   management equity subscription agreement or equity option agreement or other
   employee benefit plan or to satisfy obligations under any Equity Interests
   appreciation rights or option plan or similar arrangement; provided that the
   aggregate price paid for all such repurchased, redeemed, acquired or retired
   Equity Interests does not exceed $5.0 million in any calendar year;
   provided, further, that if the amount so paid in any calendar year is less
   than $5.0 million, such shortfall may be used to so repurchase, redeem,
   acquire or retire Equity Interests in either of the next two calendar years
   in addition to the $5.0 million that may otherwise be paid in each such
   calendar year.

In computing the amount of Restricted Payments previously made for purposes of
the immediately preceding paragraph, Restricted Payments made under clause (1)
(but only if the declaration or such dividend or other distribution has not
been counted in a prior period) and, to the extent of amounts paid to holders
other than Plains All American Pipeline or a Restricted Subsidiary, clause (4)
of this paragraph shall be included, and Restricted Payments made under clauses
(2), (3), (5), (6) and (7) and, except to the extent noted above, (4) of this
paragraph shall not be included. The amount of all Restricted Payments (other
than cash) shall be the fair market value on the date of the Restricted Payment
of the asset(s) or securities proposed to be transferred or issued by Plains
All American Pipeline or such Restricted Subsidiary, as the case may be,
pursuant to the Restricted Payment. The fair market value of any assets or
securities that are required to be valued by this covenant shall be determined
by the Board of Directors of the Managing General Partner whose resolution with
respect thereto shall be delivered to the Trustee.

  Incurrence of Indebtedness and Issuance of Disqualified Equity

   Plains All American Pipeline will not, and will not permit any of its
Restricted Subsidiaries to, directly or indirectly, create, incur, issue,
assume, guarantee or otherwise become directly or indirectly liable,
contingently or otherwise, with respect to (collectively, "incur") any
Indebtedness (including Acquired Debt and Disqualified Equity) other than
Permitted Debt; provided, however, that Plains All American Pipeline and any
Subsidiary Guarantor may incur Indebtedness (including Acquired Debt and
Disqualified Equity), if the Fixed Charge Coverage Ratio for Plains All
American Pipeline's most recently ended four full fiscal quarters for which
internal financial statements are available immediately preceding the date on
which such additional Indebtedness is incurred would have been at least 2.00 to
1.00, determined on a pro forma basis (including a pro forma application of the
net proceeds therefrom), as if the additional Indebtedness had been incurred at
the beginning of such four-quarter period.

   The first paragraph of this covenant will not prohibit the incurrence of any
of the following items of Indebtedness (collectively, "Permitted Debt"):

      (1)  the incurrence by Plains All American Pipeline and any of its
   Restricted Subsidiaries of the Indebtedness under the Credit Facilities and
   the guarantees thereof; provided that the aggregate principal

                                      33

<PAGE>

   amount of all Indebtedness of Plains All American Pipeline and its
   Restricted Subsidiaries outstanding under all Credit Facilities pursuant to
   this paragraph (1), after giving effect to such incurrence, does not exceed
   $650.0 million less the aggregate amount of all repayments of Indebtedness
   under the Credit Facilities that have been made by Plains All American
   Pipeline or any of its Restricted Subsidiaries in respect of Asset Sales to
   the extent such repayments constitute a permanent reduction of commitments
   under such Credit Facilities;

      (2)  the incurrence by Plains All American Pipeline and its Restricted
   Subsidiaries of Existing Indebtedness;

      (3)  the incurrence by Plains All American Pipeline and the Subsidiary
   Guarantors of $200.0 million in aggregate principal amount of Indebtedness
   represented by the notes and the Guarantees and the related Obligations;

      (4)  the incurrence by Plains All American Pipeline or any of its
   Restricted Subsidiaries of Indebtedness represented by Capital Lease
   Obligations, mortgage financings or purchase money obligations, in each
   case, incurred in the ordinary course of business for the purpose of
   financing all or any part of the purchase price or cost of construction,
   improvement or development of property, plant or equipment used in the
   business of Plains All American Pipeline or such Restricted Subsidiary, in
   an aggregate principal amount not to exceed $20.0 million at any time
   outstanding;

      (5)  the incurrence by Plains All American Pipeline or any of its
   Restricted Subsidiaries of Permitted Refinancing Indebtedness;

      (6)  the incurrence by Plains All American Pipeline or any of its
   Restricted Subsidiaries of intercompany Indebtedness between or among Plains
   All American Pipeline and any of its Restricted Subsidiaries; provided,
   however, that:

          (a)  if an Issuer or any Subsidiary Guarantor is the obligor on such
       Indebtedness to a Restricted Subsidiary of Plains All American Pipeline
       that is not a Subsidiary Guarantor, such Indebtedness must be expressly
       subordinated to the prior payment in full in cash of all Obligations
       with respect to the notes, in the case of Plains All American Pipeline,
       or the Guarantee of such Subsidiary Guarantor, in the case of a
       Subsidiary Guarantor,

          (b)  such intercompany Indebtedness is owed by Plains All American
       Pipeline or any of its Restricted Subsidiaries to either Plains All
       American Pipeline or a Restricted Subsidiary that is wholly owned,
       directly or indirectly, by Plains All American Pipeline, and

          (c)  (i) any subsequent issuance or transfer of Equity Interests that
       results in any such Indebtedness being held by a Person other than
       Plains All American Pipeline or a Restricted Subsidiary that is wholly
       owned, directly or indirectly, by Plains All American Pipeline and (ii)
       any sale or other transfer of any such Indebtedness to a Person that is
       not either Plains All American Pipeline or a Restricted Subsidiary that
       is wholly owned, directly or indirectly, by Plains All American
       Pipeline, shall be deemed, in each case, to constitute an incurrence of
       such Indebtedness by Plains All American Pipeline or such Restricted
       Subsidiary, as the case may be, that was not permitted by this clause
       (6);

      (7)  the incurrence by Plains All American Pipeline or any of its
   Restricted Subsidiaries of Hedging Obligations entered into in the ordinary
   course of business;

      (8)  the guarantee by Plains All American Pipeline or any of the
   Subsidiary Guarantors of Indebtedness of Plains All American Pipeline or a
   Restricted Subsidiary that was permitted to be incurred by another provision
   of this covenant;

      (9)  Indebtedness in respect of bid, performance, surety and appeal bonds
   issued for the account of Plains All American Pipeline or any of its
   Restricted Subsidiaries in the ordinary course of business, including
   guarantees and obligations of Plains All American Pipeline or any of its
   Restricted Subsidiaries with respect to letters of credit supporting such
   obligations (in each case other than for an obligation for money borrowed);

                                      34

<PAGE>

      (10)  the incurrence by Plains All American Pipeline or any of its
   Restricted Subsidiaries of additional Indebtedness in an aggregate principal
   amount not to exceed $20.0 million outstanding at any time; and

      (11)  the incurrence by Plains All American Pipeline or any of its
   Restricted Subsidiaries of Permitted Marketing Obligations, Permitted
   Contango Market Transaction Obligations and Permitted Operating Obligations.

   To the extent that Plains All American Pipeline's Unrestricted Subsidiaries
incur Non-Recourse Debt and any such Indebtedness ceases to be Non-Recourse
Debt of such Unrestricted Subsidiary, then such event shall be deemed to
constitute an incurrence of Indebtedness by a Restricted Subsidiary of Plains
All American Pipeline that was subject to this covenant.

   For purposes of determining compliance with this "--Incurrence of
Indebtedness and Issuance of Disqualified Equity" covenant, in the event that
an item of proposed Indebtedness (including Acquired Debt and Disqualified
Equity) meets the criteria of more than one of the categories of Permitted Debt
described in clauses (1) through (11) above, or is entitled to be incurred
pursuant to the first paragraph of this covenant, Plains All American Pipeline
will be permitted, in its sole discretion, to classify such item of
Indebtedness on the date it is incurred, or later reclassify all or a portion
of such item of Indebtedness in any manner that complies with this covenant. An
item of Indebtedness may be divided and classified in one or more of the types
of Permitted Debt.

  Liens

   Plains All American Pipeline will not, and will not permit any of its
Restricted Subsidiaries to, directly or indirectly, create, incur, assume or
suffer to exist any Lien of any kind securing Indebtedness on any asset now
owned or hereafter acquired, except Permitted Liens, without making effective
provision whereby all Obligations due under the notes and the Indenture or any
Guarantee, as applicable, will be secured by a Lien equally and ratably with
any and all Obligations thereby secured for so long as any such Obligations
shall be so secured or, in the case of Indebtedness so secured that is
expressly subordinated to the notes or any Guarantee, as applicable, by a Lien
prior to any Liens securing any and all Obligations thereby secured for so long
as any such Obligations shall be so secured.

  Dividend and Other Payment Restrictions Affecting Subsidiaries

   Plains All American Pipeline will not and will not permit any of its
Restricted Subsidiaries to, directly or indirectly, create or permit to exist
or become effective any encumbrance or restriction on the ability of any
Restricted Subsidiary to:

      (1)  pay dividends or make any other distributions on its Equity
   Interests to Plains All American Pipeline or any of Plains All American
   Pipeline's Restricted Subsidiaries, or pay any Indebtedness owed to Plains
   All American Pipeline or any of its Restricted Subsidiaries;

      (2)  make loans or advances to or make other investments in Plains All
   American Pipeline or any of its Restricted Subsidiaries; or

      (3)  transfer any of its properties or assets to Plains All American
   Pipeline or any of its Restricted Subsidiaries.

   However, the preceding restrictions will not apply to encumbrances or
restrictions existing under or by reason of:

      (1)  agreements as in effect on the Issue Date and any amendments,
   modifications, restatements, renewals, increases, supplements, refundings,
   replacements or refinancings of any such agreements or any Existing
   Indebtedness to which such agreement relates, provided that such amendments,
   modifications, restatements, renewals, increases, supplements, refundings,
   replacements or refinancings are no more

                                      35

<PAGE>

   restrictive, taken as a whole, with respect to such distribution, dividend
   and other payment restrictions and loan or investment restrictions than
   those contained in such agreement, as in effect on the date of the Indenture;

      (2)  the Indenture, the notes and the Guarantees;

      (3)  applicable law;

      (4)  any instrument governing Indebtedness or Equity Interests of a
   Person acquired by Plains All American Pipeline or any of its Restricted
   Subsidiaries as in effect at the time of such acquisition (except to the
   extent such Indebtedness was incurred in connection with or in contemplation
   of such acquisition), which encumbrance or restriction is not applicable to
   any Person, or the properties or assets of any Person, other than such
   Person, or the property or assets of such Person, so acquired, provided
   that, in the case of Indebtedness, such Indebtedness was permitted by the
   terms of the Indenture to be incurred;

      (5)  customary nonassignment provisions in Hydrocarbon purchase and sale
   or exchange agreements, or similar operational agreements and in licenses
   and leases entered into in the ordinary course of business;

      (6)  purchase money obligations for property acquired in the ordinary
   course of business that impose restrictions on the property so acquired of
   the nature described in clause (3) of the preceding paragraph;

      (7)  any agreement for the sale or other disposition of assets or Equity
   Interests in a Restricted Subsidiary of Plains All American Pipeline that
   contains any one or more of the restrictions described in clauses (1)
   through (3) of the preceding paragraph by such Restricted Subsidiary pending
   its sale or other disposition, provided that such sale or disposition is
   consummated, or such restrictions are canceled or terminated or lapse,
   within 90 days;

      (8)  Permitted Refinancing Indebtedness, provided that the restrictions
   contained in the agreements governing such Permitted Refinancing
   Indebtedness are no more restrictive, taken as a whole, than those contained
   in the agreements governing the Indebtedness being refinanced;

      (9)  Permitted Liens securing Indebtedness otherwise permitted to be
   issued pursuant to the provisions of the covenant described above under the
   caption "--Liens" that limit the right of Plains All American Pipeline or
   any of its Restricted Subsidiaries to dispose of the assets subject to such
   Lien;

      (10)  any agreement or instrument relating to any property or assets
   acquired after the Issue Date, so long as such encumbrance or restriction
   relates only to the property or assets so acquired and is not and was not
   created in anticipation of such acquisitions; or

      (11)  provisions with respect to the disposition or distribution of
   assets in joint venture agreements and other similar agreements entered into
   in the ordinary course of business.

  Merger, Consolidation or Sale of Assets

   Neither of the Issuers may, directly or indirectly: (1) consolidate or merge
with or into another Person (whether or not such Issuer is the survivor); or
(2) sell, assign, transfer, lease, convey or otherwise dispose of all or
substantially all of its properties or assets, in one or more related
transactions, to another Person, unless:

      (1)  either (a) such Issuer is the surviving entity of such transaction;
   or (b) the Person formed by or surviving any such consolidation or merger
   (if other than such Issuer) or to which such sale, assignment, transfer,
   lease, conveyance or other disposition shall have been made is an entity
   organized or existing under the laws of the United States, any state thereof
   or the District of Columbia, provided that PAA Finance Corp. may not
   consolidate or merge with or into any entity other than a corporation
   satisfying such requirement for so long as Plains All American Pipeline is
   not a corporation;

      (2)  the Person formed by or surviving any such consolidation or merger
   (if other than such Issuer) or the Person to which such sale, assignment,
   transfer, lease, conveyance or other disposition shall have been made (the
   "Successor") expressly assumes all the obligations of such Issuer under the
   notes and the Indenture pursuant to a supplemental Indenture in a form
   reasonably satisfactory to the Trustee;

                                      36

<PAGE>

      (3)  immediately after such transaction no Default or Event of Default
   exists;

      (4)  except in the case of a transaction involving PAA Finance Corp.,
   such Issuer or the Successor will, on the date of such transaction after
   giving pro forma effect thereto and any related financing transactions as if
   the same had occurred at the beginning of the applicable four-quarter
   period, be permitted to incur at least $1.00 of additional Indebtedness
   pursuant to the Fixed Charge Coverage Ratio test set forth in the first
   paragraph of the covenant described above under the caption "--Incurrence of
   Indebtedness and Issuance of Disqualified Equity;" and

      (5)  such Issuer has delivered to the Trustee an Officers' Certificate
   and an Opinion of Counsel, each stating that such consolidation, merger or
   disposition and, if a supplemental Indenture is required, such supplemental
   Indenture complies with the Indenture and all conditions precedent therein
   relating to such transaction have been satisfied.

Please see "--The Guarantees" for a discussion of the provisions governing a
merger or consolidation of a Subsidiary Guarantor.

   Notwithstanding the foregoing paragraph, Plains All American Pipeline is
permitted to reorganize as any other form of entity in accordance with the
following procedures provided that:

      (1)  the reorganization involves the conversion (by merger, sale,
   contribution or exchange of assets or otherwise) of Plains All American
   Pipeline into a form of entity other than a limited partnership formed under
   Delaware law;

      (2)  the entity so formed by or resulting from such reorganization is an
   entity organized or existing under the laws of the United States, any state
   thereof or the District of Columbia;

      (3)  the entity so formed by or resulting from such reorganization
   assumes all the obligations of Plains All American Pipeline under the notes
   and the Indenture pursuant to a supplemental Indenture in a form reasonably
   satisfactory to the Trustee;

      (4)  immediately after such reorganization no Default or Event of Default
   exists; and

      (5)  such reorganization is not materially adverse to the holders of the
   notes (for purposes of this clause (5) a reorganization will not be
   considered materially adverse to the holders of the notes solely because the
   successor or survivor of such reorganization (i) is subject to federal or
   state income taxation as an entity or (ii) is considered to be an
   "includable corporation" of an affiliated group of corporations within the
   meaning of Section 1504(b)(i) of the Code or any similar state or local law).

  Transactions with Affiliates

   Plains All American Pipeline will not, and will not permit any of its
Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or
otherwise dispose of any of its properties or assets to, or purchase any
property or assets from, or enter into or make or amend any transaction,
contract, agreement, understanding, loan, advance or guarantee with, or for the
benefit of, any Affiliate (each, an "Affiliate Transaction"), unless:

      (1)  such Affiliate Transaction is between or among Plains All American
   Pipeline and any of its Restricted Subsidiaries or is either (x) on terms
   that are no less favorable to Plains All American Pipeline or the relevant
   Restricted Subsidiary than those that would have been obtained in a
   comparable transaction made on an arm's-length basis with an unrelated
   Person or, if there is no such comparable transaction, on terms that are
   fair and reasonable to Plains All American Pipeline or such Restricted
   Subsidiary, or (y) in the ordinary course of business and consistent with
   past practice; and

      (2)  Plains All American Pipeline delivers to the Trustee:

          (a)  with respect to any Affiliate Transaction or series of related
       Affiliate Transactions involving aggregate consideration with a fair
       market value in excess of $10.0 million, an Officers' Certificate
       certifying that such Affiliate Transaction complies with this covenant
       and that such Affiliate

                                      37

<PAGE>

       Transaction has been approved (either pursuant to specific or general
       resolutions) by a majority of the disinterested members of the Board of
       Directors of the Managing General Partner or has been approved by an
       officer pursuant to a delegation (specific or general) of authority from
       such Board of Directors; and

          (b)  with respect to any Affiliate Transaction or series of related
       Affiliate Transactions involving aggregate consideration with a fair
       market value in excess of $25.0 million, (A) a resolution of the Board
       of Directors of the Managing General Partner set forth in an Officers'
       Certificate certifying that such Affiliate Transaction complies with
       this covenant and that such Affiliate Transaction has been approved by a
       majority of the disinterested members of such Board of Directors and (B)
       an opinion as to the fairness to Plains All American Pipeline of such
       Affiliate Transaction from a financial point of view issued by an
       accounting, appraisal or investment banking firm that is recognized
       nationally in the energy industry as an expert in rendering fairness
       opinions on transactions such as those proposed.

   The following items shall not be deemed to be Affiliate Transactions and,
therefore, will not be subject to the provisions of the prior paragraph:

      (1)  any employment, equity award, equity option or equity appreciation
   agreement or plan entered into by Plains All American Pipeline or any of its
   Restricted Subsidiaries in the ordinary course of business of Plains All
   American Pipeline or such Restricted Subsidiary;

      (2)  Restricted Payments that are permitted by the provisions of the
   Indenture described above under the caption "--Restricted Payments";

      (3)  transactions effected in accordance with the terms of agreements as
   in effect on the Issue Date;

      (4)  transactions effected in accordance with the Marketing Agreement
   that are fair and reasonable to Plains All American Pipeline and its
   Restricted Subsidiaries;

      (5)  customary compensation, indemnification and other benefits made
   available to officers, directors or employees of Plains All American
   Pipeline, a Restricted Subsidiary of Plains All American Pipeline or the
   Managing General Partner, including reimbursement or advancement of
   out-of-pocket expenses and provisions of officers' and directors' liability
   insurance; and

      (6)  loans to officers and employees made in the ordinary course of
   business in an aggregate amount not to exceed $1.0 million at any one time
   outstanding.

  Additional Subsidiary Guarantees

   If any Restricted Subsidiary of Plains All American Pipeline that is not
then a Subsidiary Guarantor (a) guarantees Indebtedness of either of the
Issuers or any other Restricted Subsidiary or (b) incurs Indebtedness (other
than Permitted Debt described in clause (6), (7), (9), (10) or (11) of the
definition thereof), in either case after the Issue Date, then such Restricted
Subsidiary shall execute and deliver a supplemental indenture providing for the
guarantee of the payment of the notes by such Restricted Subsidiary.

  Designation of Restricted and Unrestricted Subsidiaries

   The Board of Directors of the Managing General Partner may designate any
Restricted Subsidiary of Plains All American Pipeline to be an Unrestricted
Subsidiary if that designation would not cause a Default or an Event of
Default. If a Restricted Subsidiary of Plains All American Pipeline is
designated as an Unrestricted Subsidiary, all outstanding Investments owned by
Plains All American Pipeline and its Restricted Subsidiaries in the Subsidiary
so designated will be deemed to be an Investment made as of the time of such
designation and will reduce the amount available for Restricted Payments under
the first paragraph of the covenant described above under the caption
"--Restricted Payments," for Permitted Investments or for Permitted Business
Investments, as applicable. All such outstanding Investments will be valued at
their fair market value at the time of such

                                      38

<PAGE>

designation. That designation will only be permitted if such Restricted
Payment, Permitted Investment or Permitted Business Investment would be
permitted at that time and such Restricted Subsidiary otherwise meets the
definition of an Unrestricted Subsidiary. All Subsidiaries of an Unrestricted
Subsidiary shall also be Unrestricted Subsidiaries. Upon the designation of a
Restricted Subsidiary that is a Subsidiary Guarantor as an Unrestricted
Subsidiary, the Guarantee of such entity shall be released.

   The Board of Directors of the Managing General Partner may redesignate any
Unrestricted Subsidiary to be a Restricted Subsidiary if such designation
complies with the requirements of the Indenture described in the definition of
"Unrestricted Subsidiary."

  Sale and Lease-Back Transactions

   Plains All American Pipeline will not, and will not permit any of its
Restricted Subsidiaries to, enter into any sale and lease-back transaction;
provided that Plains All American Pipeline or any of its Restricted
Subsidiaries that is a Subsidiary Guarantor may enter into a sale and
lease-back transaction if:

      (1)  Plains All American Pipeline or that Subsidiary Guarantor, as
   applicable, could have (a) incurred Indebtedness in an amount equal to the
   Attributable Debt relating to such sale and lease-back transaction under the
   Fixed Charge Coverage Ratio test in the first paragraph of the covenant
   described above under the caption "--Incurrence of Indebtedness and Issuance
   of Disqualified Equity," and (b) incurred a Lien to secure such Indebtedness
   pursuant to the covenant described above under the caption "--Liens"; or

      (2)  the gross cash proceeds of that sale and lease-back transaction are
   at least equal to the fair market value, as determined in good faith by the
   Board of Directors, of the property that is the subject of such sale and
   lease-back transaction, and Plains All American Pipeline or such Subsidiary
   Guarantor applies such proceeds in compliance with the covenant described
   under "--Repurchase at the Option of Holders--Asset Sales."

  Business Activities; Restrictions on PAA Finance Corp.'s Indebtedness

   Plains All American Pipeline will not, and will not permit any of its
Restricted Subsidiaries to, materially or substantially engage in any business
other than Permitted Businesses. PAA Finance Corp. may not incur Indebtedness
unless (1) Plains All American Pipeline is a co-obligor or guarantor of such
Indebtedness or (2) the net proceeds of such Indebtedness are loaned to Plains
All American Pipeline, used to acquire outstanding debt securities issued by
Plains All American Pipeline or used to repay Indebtedness of Plains All
American Pipeline as permitted under the covenant described above under the
caption "--Incurrence of Indebtedness and Issuance of Disqualified Equity." PAA
Finance Corp. may not engage in any business not related directly or indirectly
to obtaining money or arranging financing for Plains All American Pipeline or
its Restricted Subsidiaries.

  Payments for Consent

   Plains All American Pipeline will not, and will not permit any of its
Subsidiaries to, directly or indirectly, pay or cause to be paid any
consideration to or for the benefit of any holder of notes for or as an
inducement to any consent, waiver or amendment of any of the terms or
provisions of the Indenture or the notes unless such consideration is offered
to be paid and is paid to all holders of the notes that consent, waive or agree
to amend in the time frame set forth in the solicitation documents relating to
such consent, waiver or agreement.

  SEC Reports

   Notwithstanding that Plains All American Pipeline may not be required to
remain subject to the reporting requirements of Section 13 or 15(d) of the
Exchange Act, Plains All American Pipeline will file with the SEC and provide
the trustee and holders with annual reports and such information, documents and
other reports specified in Sections 13 and 15(d) of the Exchange Act.

   In the event that at any time (a) the rating assigned to the notes by at
least two of S&P, Moody's or Fitch is an Investment Grade Rating and (b) no

their Restricted Subsidiaries will no longer be subject to the provisions of
the Indenture described above under the caption "Repurchase at the Option of

   Pipeline's Restricted Subsidiaries (or the payment of which is guaranteed by
   Plains All American

                                      40

<PAGE>

   Pipeline or any of its Restricted Subsidiaries), whether such Indebtedness
   or guarantee now exists or is created after the date of the Indenture, if
   that default:

          (a)  is caused by a failure to pay principal of or premium, if any,
       or interest on such Indebtedness prior to the expiration of the grace
       period provided in such Indebtedness on the date of such default (a
       "Payment Default") or

          (b)  results in the acceleration of such Indebtedness prior to its
       express maturity, and

   in each case, the principal amount of any such Indebtedness, together with
   the principal amount of any other such Indebtedness under which there has
   been a Payment Default or the maturity of which has been so accelerated,
   aggregates $10.0 million or more; provided, further, that if any such
   default is cured or waived or any such acceleration rescinded, or such
   Indebtedness is repaid, within a period of 30 days from the continuation of
   such default beyond the applicable grace period or the occurrence of such
   acceleration, as the case may be, such Event of Default and any
   consequential acceleration of the notes shall be automatically rescinded, so
   long as such rescission does not conflict with any judgment or decree;

      (6)  failure by an Issuer or any of Plains All American Pipeline's
   Restricted Subsidiaries to pay final judgments aggregating in excess of
   $10.0 million, which judgments are not paid, discharged or stayed for a
   period of 60 days;

      (7)  except as permitted by the Indenture, any Guarantee shall be held in
   any judicial proceeding to be unenforceable or invalid or shall cease for
   any reason to be in full force and effect or any Subsidiary Guarantor, or
   any Person acting on behalf of any Subsidiary Guarantor, shall deny or
   disaffirm its obligations under its Guarantee; and

      (8)  certain events of bankruptcy or insolvency with respect to an Issuer
   or any of Plains All American Pipeline's Restricted Subsidiaries that is a
   Significant Subsidiary or any group of Restricted Subsidiaries that, taken
   together, would constitute a Significant Subsidiary.

   In the case of an Event of Default arising from certain events of bankruptcy
or insolvency, all outstanding notes will become due and payable immediately
without further action or notice. If any other Event of Default occurs and is
continuing, the Trustee or the holders of at least 25% in principal amount of
the then outstanding notes may declare all the notes to be due and payable
immediately.

   Holders of the notes may not enforce the Indenture or the notes except as
provided in the Indenture. Subject to certain limitations, holders of a
majority in principal amount of the then outstanding notes may direct the
Trustee in its exercise of any trust or power. The Trustee may withhold from
holders of the notes notice of any continuing Default or Event of Default
(except a Default or Event of Default relating to the payment of principal,
premium, if any, interest or Additional Interest, if any) if it determines that
withholding notice is in their interest.

   The holders of a majority in aggregate principal amount of the notes then
outstanding by notice to the Trustee may on behalf of the holders of all of the
notes waive any existing Default or Event of Default and its consequences under
the Indenture except a continuing Default or Event of Default in the payment of
interest (or Additional Interest or premium, if any) on, or the principal of,
the notes.

   The Issuers and the Subsidiary Guarantors are required to deliver to the
Trustee annually a statement regarding compliance with the Indenture. Upon any
officer of the Managing General Partner or PAA Finance Corp. becoming aware of
any Default or Event of Default, the Issuers are required to deliver to the
Trustee a statement specifying such Default or Event of Default.

No Personal Liability of Directors, Officers, Employees and Unitholders

   No past, present or future director, officer, partner, employee,
incorporator, manager, stockholder, unitholder or member of the Issuers, the
General Partner, the Managing General Partner or any Subsidiary Guarantor, as
such, shall have any liability for any obligations of the Issuers or the
Subsidiary Guarantors under

                                      41

<PAGE>

the notes, the Indenture, the Guarantees or for any claim based on, in respect
of, or by reason of, such obligations or their creation. Each holder of notes
by accepting a note waives and releases all such liability. The waiver and
release are part of the consideration for issuance of the notes. The waiver may
not be effective to waive liabilities under the federal securities laws.

Legal Defeasance and Covenant Defeasance

   The Issuers may, at their option and at any time, elect to have all of the
Issuers' obligations discharged with respect to the outstanding notes and all
obligations of the Subsidiary Guarantors discharged with respect to their
Guarantees ("Legal Defeasance"), except for:

      (1)  the rights of holders of outstanding notes to receive payments in
   respect of the principal of, premium, if any, interest and Additional
   Interest, if any, on such notes when such payments are due (but not the
   Change of Control Payment or the payment pursuant to an Asset Sale Offer)
   from the trust referred to below;

      (2)  the Issuers' obligations with respect to the notes concerning
   issuing temporary notes, registration of notes, mutilated, destroyed, lost
   or stolen notes and the maintenance of an office or agency for payment and
   money for security payments held in trust;

      (3)  the rights, powers, trusts, duties and immunities of the Trustee,
   and the Issuers' obligations in connection therewith;

      (4)  the Legal Defeasance provisions of the Indenture; and

      (5)  the Issuers' rights of optional redemption.

   In addition, the Issuers may, at their option and at any time, elect to have
the obligations of the Issuers and the Subsidiary Guarantors released with
respect to certain covenants that are described in the Indenture ("Covenant
Defeasance") and thereafter any omission to comply with those covenants shall
not constitute a Default or Event of Default with respect to the notes. In the
event Covenant Defeasance occurs, certain events (not including nonpayment,
bankruptcy, receivership, rehabilitation and insolvency events) described under
"Events of Default and Remedies" will no longer constitute an Event of Default
with respect to the notes.

   In order to exercise either Legal Defeasance or Covenant Defeasance:

      (1)  the Issuers must irrevocably deposit with the Trustee, in trust, for
   the benefit of the holders of the notes, cash in U.S. dollars, U.S.
   Government Obligations, or a combination thereof, in such amounts as will be
   sufficient, in the written opinion of a nationally recognized firm of
   independent public accountants, to pay the principal of, premium, if any,
   interest and Additional Interest, if any, on the outstanding notes at the
   Stated Maturity thereof or on the applicable redemption date, as the case
   may be, and the Issuers must specify whether the notes are being defeased to
   maturity or to a particular redemption date;

      (2)  in the case of Legal Defeasance, the Issuers shall have delivered to
   the Trustee an Opinion of Counsel reasonably acceptable to the Trustee
   confirming that (a) the Issuers have received from, or there has been
   published by, the Internal Revenue Service a ruling or (b) since the date of
   the Indenture, there has been a change in the applicable federal income tax
   law, in either case to the effect that, and based thereon such Opinion of
   Counsel shall confirm that, the holders of the outstanding notes will not
   recognize income, gain or loss for federal income tax purposes as a result
   of such Legal Defeasance and will be subject to federal income tax on the
   same amounts, in the same manner and at the same times as would have been
   the case if such Legal Defeasance had not occurred;

      (3)  in the case of Covenant Defeasance, the Issuers shall have delivered
   to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee
   confirming that the holders of the outstanding notes will not recognize
   income, gain or loss for federal income tax purposes as a result of such
   Covenant Defeasance and will be subject to federal income tax on the same
   amounts, in the same manner and at the same times as would have been the
   case if such Covenant Defeasance had not occurred;

                                      42

<PAGE>

      (4)  no Default or Event of Default shall have occurred and be continuing
   either (a) on the date of such deposit (other than a Default or Event of
   Default resulting from the incurrence of Indebtedness all or a portion of
   the proceeds of which shall be applied to such deposit); or (b) insofar as
   Events of Default from bankruptcy or insolvency events are concerned, at any
   time in the period ending on the 91st day after the date of deposit;

      (5)  such Legal Defeasance or Covenant Defeasance will not result in a
   breach or violation of, or constitute a default under, any material
   agreement or instrument (other than the Indenture) to which Plains All
   American Pipeline or any of its Restricted Subsidiaries is a party or by
   which Plains All American Pipeline or any of its Restricted Subsidiaries is
   bound;

      (6)  the Issuers must have delivered to the Trustee an Opinion of Counsel
   to the effect that after the 91st day following the deposit, the trust funds
   will not be subject to the effect of any applicable bankruptcy, insolvency,
   reorganization or similar laws affecting creditors' rights generally;

      (7)  the Issuers must deliver to the Trustee an Officers' Certificate
   stating that the deposit was not made by the Issuers with the intent of
   preferring the holders of notes over the other creditors of the Issuers with
   the intent of defeating, hindering, delaying or defrauding other creditors
   of the Issuers; and

      (8)  the Issuers must deliver to the Trustee an Officers' Certificate and
   an Opinion of Counsel, each stating that all conditions precedent relating
   to the defeasance have been complied with.

Amendment, Supplement and Waiver

   Generally, the Issuers, the Subsidiary Guarantors and the Trustee may amend
or supplement the Indenture, the Guarantees and the notes with the written
consent of the holders of at least a majority in principal amount of the notes
then outstanding, including provisions relating to the covenants described
above under the caption "--Repurchase at the Option of Holders." However,
without the consent of each holder affected, an amendment, supplement or waiver
may not (with respect to any notes held by a nonconsenting holder):

      (1)  reduce the principal amount of notes whose holders must consent to
   an amendment, supplement or waiver;

      (2)  reduce the principal of or change the fixed maturity of any note;

      (3)  reduce or waive the premium payable upon redemption or alter or
   waive the provisions with respect to the redemption of the notes (other than
   provisions relating to the covenants described above under the caption
   "--Repurchase at the Option of Holders");

      (4)  reduce the rate of or change the time for payment of interest on any
   note;

      (5)  waive a Default or an Event of Default in the payment of principal
   of or premium, if any, or interest on, or Additional Interest, if any, with
   respect to, the notes (except a rescission of acceleration of the notes by
   the holders of at least a majority in aggregate principal amount of the
   notes and a waiver of the payment default that resulted from such
   acceleration);

      (6)  release any security that may have been granted with respect to the
   notes;

      (7)  make any note payable in currency other than that stated in the
   notes;

      (8)  make any change in the provisions of the Indenture relating to
   waivers of past Defaults or the rights of holders of notes to receive
   payments of principal of or premium, if any, interest or Additional
   Interest, if any, on the notes;

      (9)  waive a redemption payment with respect to any note (other than a
   payment required by one of the covenants described above under the caption
   "--Repurchase at the Option of Holders");

      (10)  except as otherwise permitted in the Indenture, release any
   Subsidiary Guarantor from its obligations under its Guarantee or the
   Indenture or change any Guarantee in any manner that would adversely affect
   the rights of holders; or

                                      43

<PAGE>

      (11)  make any change in the preceding amendment, supplement and waiver
   provisions (except to increase any percentage set forth therein).

   Notwithstanding the foregoing, without the consent of any holder of notes,
the Issuers, the Subsidiary Guarantors and the Trustee may amend or supplement
the Indenture or the notes:

      (1)  to cure any ambiguity, defect or inconsistency;

      (2)  to provide for uncertificated notes in addition to or in place of
   certificated notes;

      (3)  to provide for the assumption of an Issuer's or Subsidiary
   Guarantor's obligations to holders of notes in the case of a merger or
   consolidation or sale of all or substantially all of such Issuer's or
   Subsidiary Guarantor's assets;

      (4)  to add or release Subsidiary Guarantors pursuant to the terms of the
   Indenture;

      (5)  to make any changes that would provide any additional rights or
   benefits to the holders of notes that do not, taken as a whole, adversely
   affect the rights under the Indenture of any holder of the notes;

      (6)  to comply with requirements of the SEC in order to effect or
   maintain the qualification of the Indenture under the Trust Indenture Act;

      (7)  to evidence or provide for the acceptance of appointment under the
   Indenture of a successor Trustee;

      (8)  to add any additional Events of Default; or

      (9)  to secure the notes and/or the Guarantees.

Concerning the Trustee

   If the Trustee becomes a creditor of an Issuer or any Subsidiary Guarantor,
the Indenture limits its right to obtain payment of claims in certain cases, or
to realize on certain property received in respect of any such claim as
security or otherwise. The Trustee will be permitted to engage in other
transactions; however, if it acquires any conflicting interest and a Default
occurs it must eliminate such conflict within 90 days, apply to the SEC for
permission to continue or resign.

   The holders of a majority in principal amount of the then outstanding notes
will have the right to direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee, subject to
certain exceptions. The Indenture provides that in case an Event of Default
shall occur and be continuing, the Trustee will be required, in the exercise of
its power, to use the degree of care of a prudent person in the conduct of his
own affairs. Subject to such provisions, the Trustee will be under no
obligation to exercise any of its rights or powers under the Indenture at the
request of any holder of notes, unless such holder shall have offered to the
Trustee security or indemnity satisfactory to it against any cost, liability or
expense.

period shall mean the sum of rental and other payments required to be paid with
respect to such period by the lessee thereunder, excluding any amounts required
to be paid by such lessee on account of maintenance and repairs, insurance,
taxes, assessments, water rates or similar charges. In the case of any lease
that is terminable by the lessee upon payment of penalty, such net rental
payment shall also include the amount of such penalty, but no rent shall be

<PAGE>

   Notwithstanding the preceding, the provision for taxes based on the income
or profits of, and the depreciation and amortization and other non-cash charges
of, a Restricted Subsidiary of Plains All American Pipeline shall be added to
Consolidated Net Income to compute Consolidated Cash Flow of Plains All
American Pipeline only to the extent that a corresponding amount would be
permitted at the date of determination to be dividended or distributed to
Plains All American Pipeline by such Restricted Subsidiary without prior
approval (that has not been obtained), pursuant to the terms of its charter and
all agreements, instruments, judgments, decrees, orders, statutes, rules and
governmental regulations applicable to that Restricted Subsidiary or its
stockholders, partners or members.

   "Consolidated Net Income" means, with respect to any specified Person for
any period, the aggregate of the Net Income of such Person and its Restricted
Subsidiaries for such period, on a consolidated basis, determined in accordance
with GAAP; provided that:

      (1)  the aggregate Net Income (but not net loss in excess of such
   aggregate Net Income) of all Persons that are Unrestricted Subsidiaries
   shall be excluded (without duplication);

      (2)  the earnings included therein attributable to all entities that are
   accounted for by the equity method of accounting and the aggregate Net
   Income (but not net loss in excess of such aggregate Net Income) included
   therein attributable to all entities constituting Joint Ventures that are

determined by such Person to be the rate of interest implicit in such Capital
Lease Obligation in accordance with GAAP; (b) interest on Indebtedness that is
determined on a fluctuating basis shall be deemed to have accrued at a fixed
rate per annum equal to the rate of interest of such Indebtedness in effect on

accrue during the fiscal quarter in which the Transaction Date occurs and the
three fiscal quarters immediately subsequent to such fiscal quarter on the
aggregate amount of Indebtedness outstanding on the Transaction Date, including
any Indebtedness proposed to be incurred on such date and excluding any
Indebtedness repaid with the proceeds of such Indebtedness (as though all such
Indebtedness was incurred or repaid on the first day of the quarter in which
the Transaction Date occurred).

   In addition to, but without duplication of, the preceding paragraph, for
purposes of this definition Consolidated Cash Flow shall be calculated after
giving effect (without duplication), on a pro forma basis for the Pro Forma
Period (but no longer), to:

      (1)  any Investment, during the period commencing on the first day of the
   Pro Forma Period to and including the Transaction Date (the "Reference
   Period"), in any other Person that, as a result of such Investment, becomes

   Restricted Subsidiary of such Person, as if such acquisition had occurred on
   the first day of the Reference Period;

      (3)  any sales or other dispositions of assets by such Person or any

   in each case as if such incurrence, Investment, repayment, acquisition or
   assets sale had occurred on the first day of the Reference Period; and

      (4)  interest income reasonably anticipated by such Person to be received
   during the Pro Forma Period from cash or Cash Equivalents held by such
   Person or any Restricted Subsidiary of such Person, which cash or Cash
   Equivalents exist on the Transaction Date or will exist as a result of the
   transaction giving rise to the need to calculate the Fixed Charge Coverage
   Ratio.

                       FEDERAL INCOME TAX CONSIDERATIONS

Federal Income Tax Considerations of the Exchange of Outstanding Notes for New
Notes

   The following discussion is a summary of certain federal income tax
considerations relevant to the exchange of outstanding notes for new notes, but
does not purport to be a complete analysis of all potential tax effects. The
discussion is based upon the Internal Revenue Code of 1986, as amended,
Treasury Regulations, Internal Revenue Service rulings and pronouncements and
judicial decisions now in effect, all of which may be subject to change at any
time by legislative, judicial or administrative action. These changes may be
applied retroactively in a manner that could adversely affect a holder of new
notes. The description does not consider the effect of any applicable foreign,
state, local or other tax laws or estate or gift tax considerations.

   We believe that the exchange of outstanding notes for new notes should not
be an exchange or otherwise a taxable event to a holder for United States
federal income tax purposes. Accordingly, a holder should have the same
adjusted issue price, adjusted basis and holding period in the new notes as it
had in the outstanding notes immediately before the exchange.

                                      63

<PAGE>

                             PLAN OF DISTRIBUTION

   Based on interpretations by the staff of the SEC in no action letters issued
to third parties, we believe that you may transfer new notes issued under the
exchange offer in exchange for the outstanding notes if:

  .   you acquire the new notes in the ordinary course of your business; and

  .   you are not engaged in, and do not intend to engage in, and have no
      arrangement or understanding with any person to participate in, a
      distribution of such new notes.
   You may not participate in the exchange offer if you are:

  .   our "affiliate" within the meaning of Rule 405 under the Securities Act;
      or

  .   a broker-dealer that acquired outstanding notes directly from us.

   Each broker-dealer that receives new notes for its own account pursuant to
the exchange offer must acknowledge that it will deliver a prospectus in
connection with any resale of such new notes. To date, the staff of the SEC has
taken the position that broker-dealers may fulfill their prospectus delivery
requirements with respect to transactions involving an exchange of securities
such as this exchange offer, other than a resale of an unsold allotment from
the original sale of the outstanding notes, with the prospectus contained in
this registration statement. This prospectus, as it may be amended or
supplemented from time to time, may be used by a broker-dealer in connection
with resales of new notes received in exchange for outstanding notes where such
outstanding notes were acquired as a result of market-making activities or
other trading activities. We have agreed that, for a period of up to one year
after the consummation of the exchange offer, we will make this prospectus, as
amended or supplemented, promptly available to any broker-dealer for use in
connection with any such resale. In addition, until         , 2002, all dealers
effecting transactions in new notes may be required to deliver a prospectus.

   If you wish to exchange your outstanding notes for new notes in the exchange
offer, you will be required to make representations to us as described in
"Exchange Offer--Purpose and Effect of the Exchange Offer" and "--Procedures
for Tendering--Your Representations to Us" in this prospectus and in the letter
of transmittal. In addition, if you are a broker-dealer who receives new notes
for your own account in exchange for outstanding notes that were acquired by
you as a result of market-making activities or other trading activities, you
will be required to acknowledge that you will deliver a prospectus in
connection with any resale by you of such new notes.

   We will not receive any proceeds from any sale of new notes by
broker-dealers. New notes received by broker-dealers for their own account
pursuant to the exchange offer may be sold from time to time in one or more
transactions:

  .   in the over-the-counter market;

  .   in negotiated transactions;

  .   through the writing of options on the new notes or a combination of such
      methods of resale;

  .   at market prices prevailing at the time of resale; and

  .   at prices related to such prevailing market prices or negotiated prices.

   Any such resale may be made directly to purchasers or to or through brokers
or dealers who may receive compensation in the form of commissions or
concessions from any such broker-dealer or the purchasers of any such new
notes. Any broker-dealer that resells new notes that were received by it for
its own account pursuant to the exchange offer and any broker or dealer that
participates in a distribution of such new notes may be deemed to be an
"underwriter" within the meaning of the Securities Act and any profit of any
such resale of new notes

                                      64

<PAGE>

and any commissions or concessions received by any such persons may be deemed
to be underwriting compensation under the Securities Act. The letter of
transmittal states that by acknowledging that it will deliver and by delivering
a prospectus, a broker-dealer will not be deemed to admit that it is an
"underwriter" within the meaning of the Securities Act.

   For a period of one year after the consummation of the exchange offer, we
will promptly send additional copies of this prospectus and any amendment or
supplement to this prospectus to any broker-dealer that requests such documents
in the letter of transmittal. We have agreed to pay all expenses incident to
the exchange offer (including the expenses of one counsel for the holders of
the outstanding notes) other than commissions or concessions of any
broker-dealers and will indemnify the holders of the outstanding notes
(including any broker-dealers) against certain liabilities, including
liabilities under the Securities Act.

                                 LEGAL MATTERS

   The validity of the new notes offered in this exchange offer will be passed
upon for us by Vinson & Elkins L.L.P.

                    INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.  Indemnification Of Officers And Directors

   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
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 22.  Undertakings

   Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of any
Registrant, we have been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by any Registrant of expenses incurred
or paid by a director, officer or controlling person of such Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, such 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.

   Each 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 of 1933;

      (b)  To reflect in the prospectus any facts or events arising after the
   effective date of the registration statement (or the most recent
   post-effective amendment thereof) which, individually or in the aggregate,
   represent a fundamental change in the information set forth in the
   registration statement. Notwithstanding the foregoing, any increase or
   decrease in volume of securities offered (if the total dollar value of
   securities offered would not exceed that which was registered) and any
   deviation from the low or high end of the estimated maximum offering range
   may be reflected in the form of prospectus filed with the Commission
   pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
   price represent no more than 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 the registration statement or any
   material change to such information in the registration statement; and

   (2)  That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

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

   (4)  That, for purposes of determining any liability under the Securities
Act of 1933, each filing of the registrants annual report pursuant to section
13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
section 15(d) of the Securities Exchange Act of 1934) that is incorporated by
reference in the registration statement shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

   (5)  To respond to requests for information that is incorporated by
reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this
Form, within one business day of receipt of such request, and to send the
incorporated documents by first class mail or other equally prompt means.

This includes information contained in documents filed subsequent to the
effective date of the registration statement through the date of responding to
the request.

   (6)  To supply by means of a post-effective amendment all information
concerning a transaction, and the company being acquired involved therein, that
was not the subject of and included in this Registration Statement when it
became effective.
