PLAINS ALL AMERICAN PIPELINE, L.P. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited) Note 1 -- Organization and Accounting Policies We are a Delaware limited partnership that was formed in September, 1998 to acquire and operate the midstream crude oil business and assets of Plains Resources Inc. and its wholly owned subsidiaries. On November 23, 1998, we completed our initial public offering and the transactions whereby we became the successor to the business of the midstream subsidiaries of Plains Resources. Our operations are conducted through Plains Marketing, L.P., All American Pipeline, L.P. and Plains Marketing Canada, L.P. The terms "Plains All American" and the "Partnership" herein refer to Plains All American Pipeline, L.P. and its affiliated operating partnerships. We are engaged in interstate and intrastate transportation, marketing, and terminalling of crude oil. Our operations are conducted primarily in Texas, California, Oklahoma, Louisiana, the Gulf of Mexico and the Canadian Provinces of Alberta and Saskatchewan. The accompanying financial statements and related notes present our consolidated financial position as of June 30, 2001 and December 31, 2000; the results of our operations for the three and six months ended June 30, 2001 and 2000; cash flows for the six months ended June 30, 2001 and 2000; and changes in partners' capital for the six months ended June 30, 2001. The financial statements have been prepared in accordance with the instructions to interim reporting as prescribed by the Securities and Exchange Commission ("SEC"). All adjustments consisting only of normal recurring adjustments that, in the opinion of management, were necessary for a fair statement of the results for the interim periods, have been reflected. All significant intercompany transactions have been eliminated. Certain reclassifications have been made to prior period amounts to conform with current period presentation. The results of operations for the three and six months ended June 30, 2001 should not be taken as indicative of the results to be expected for the full year. The interim financial statements should be read in conjunction with our consolidated financial statements and notes thereto presented in our 2000 Annual Report on Form 10-K. Note 2 -- Transfer of Our General Partner On June 8, 2001, Plains All American Inc., our former general partner and a wholly owned subsidiary of Plains Resources Inc., sold a portion of its ownership in our partnership to an investor group including, among others, affiliates of Kayne Anderson Capital Advisors, EnCap Investments, Strome Investment Management, James C. Flores and our current management for aggregate consideration of approximately $155.2 million. In connection with this transaction, a new entity jointly owned by the investor group and Plains Resources Inc. became our general partner and assumed all of the general partner's rights and obligations under our partnership agreement. The investor group purchased approximately 5.2 million subordinated units from an affiliate of Plains Resources Inc. As a result of this transaction and our recent equity offering, Plains Resources' effective ownership in us has been reduced to approximately 33% from approximately 54%. Plains Resources has agreed to make available to our management group an additional 2% of the general partner interest on substantially the same terms as the other investors. Note 3 -- Equity Offering On May 31, 2001, we completed a public offering of 3,750,000 common units. Additionally, on June 22, 2001, we issued another 216,700 units pursuant to the underwriter's overallotment option. Total net cash proceeds from the offering (which aggregates to 3,966,700 units), including our general partner's proportionate contribution, were approximately $100.7 million and were used to repay borrowings under our revolving credit facility, a portion of which were used to finance the Murphy Acquisition (see Note 6). Note 4 -- Derivative Instruments and Hedging Activities On January 1, 2001, we adopted Statement of Financial Accounting Standards ("SFAS") No. 133 "Accounting for Derivative Instruments and Hedging Activities" as amended by SFAS 137 and SFAS 138. Under SFAS 133, all derivative instruments are recorded on the balance sheet at fair value. If the derivative does not qualify as a hedge or is not designated as a hedge, the gain or loss on the derivative is recognized currently in earnings. To qualify for hedge accounting, the derivative must qualify either as a fair value hedge, cash flow hedge or foreign currency hedge. As of June 30, 2001, our transactions consisted of only cash flow and foreign currency hedges (which are defined as fair value hedges) and the remaining discussion will relate exclusively to these types of derivative instruments. If the derivative qualifies for cash flow hedge accounting, the gain or loss on the derivative is deferred in accumulated Other Comprehensive Income ("OCI"), a 7

component of Partners' Capital, to the extent the hedge is effective. Fair value hedge gains or losses are taken directly to earnings in the current period. The relationship between the hedging instrument and the hedged item must be highly effective in achieving the offset of changes in cash flows attributable to the hedged risk both at the inception of the contract and on an ongoing basis. Hedge accounting is discontinued prospectively when a hedge instrument becomes ineffective. Gains and losses deferred in OCI related to cash flow hedges that become ineffective remain unchanged until the related product is delivered. If it is determined that it is probable that a hedged forecasted transaction will not occur, deferred gains or losses on the hedging instrument are recognized in earnings immediately. Gains and losses on hedging instruments related to OCI and adjustments to carrying amounts on hedged volumes are included in revenues in the period that the related volumes are delivered. Gains and losses of hedging instruments, which represent hedge ineffectiveness, are included in earnings in the period in which they occur. We utilize various derivative instruments, for purposes other than trading, to hedge our exposure to price fluctuations on crude in storage and expected purchases, sales and transportation of crude oil. The derivative instruments consist primarily of futures and option contracts traded on the New York Mercantile Exchange. We also utilize interest rate collars to manage the interest rate exposure on our long-term debt and foreign currency hedges to manage exchange rate exposure. On January 1, 2001, in accordance with the transition provisions of SFAS 133, we recorded a loss of $8.3 million in OCI representing the cumulative effect of an accounting change to recognize at fair value all cash flow derivatives. We also recorded a noncash gain of $0.5 million in earnings as a cumulative effect adjustment. At June 30, 2001, a $5.8 million unrealized loss was recorded to OCI together with related assets and liabilities of $6.9 million and $12.9 million, respectively. Earnings included a non-cash gain of $0.2 million related to the ineffective portion of our cash flow hedges, as well as the gain/loss on our fair value hedges (included in revenues in the income statement). Our hedge-related assets and liabilities are included in other current assets and other current liabilities in the balance sheet. As of June 30, 2001, the total amount of deferred net losses on derivative instruments recorded in OCI are expected to be reclassified to earnings during the next twelve-month period. At June 30, 2001 we had the following open crude oil hedge positions: 2001 2002 ------------------ ------------------- 3rd Qtr 4th Qtr 1st Qtr 2nd Qtr ------- ------- ------- ------- Volume (bbls) Short positions 812,000 - - - Long positions - 762,000 132,000 250,000 Average price ($/bbl) $25.13 $26.84 $27.28 $25.56 At June 30, 2001, we had an interest rate collar arrangement to protect interest rate fluctuations on a portion of our outstanding debt for an aggregate notional principal amount of $125.0 million. This instrument is based on LIBOR rates and provides for a floor of 6.1% and a ceiling of 8.0% with an expiration date of August 2002. During the second quarter of 2001, gains of $.5 million were relieved from OCI and the fair value of open positions decreased $2.7 million. Additionally, certain derivative positions were terminated prior to maturity. As such, a $5.8 million loss related to all positions (open and closed hedges) was recorded in OCI at June 30, 2001. We formally document all relationships between hedging instruments and hedged items, as well as our risk management objectives and strategy for undertaking the hedge. Hedge effectiveness is measured on a quarterly basis. This process includes specific identification of the hedging instrument and the hedge transaction, the nature of the risk being hedged and how the hedging instrument's effectiveness will be assessed. Both at the inception of the hedge and on an ongoing basis, we assess whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows of hedged items. No amounts were excluded from the computation of hedge effectiveness. Note 5 -- Comprehensive Income Comprehensive income includes net income and certain items recorded directly to Partners' Capital and classified as OCI. Following the adoption of SFAS 133, we recorded a charge to OCI of $8.3 million related to the change in fair value 8

of certain derivative financial instruments that qualified for cash flow hedge accounting. The following table reflects comprehensive income for the six months ended June 30, 2001 (in thousands of dollars): Total Comprehensive Income at January 1, 2001 $ - Cumulative effect of change in accounting principle (8,337) Reclassification adjustment for settled contracts 6,791 Changes in fair value of open hedging positions (4,340) Currency translation adjustment 48 ------- Other Comprehensive Income at June 30, 2001 (5,838) Net income for the six months ended June 30, 2001 20,082 ------- Total Comprehensive Income at June 30, 2001 $14,244 ======= Note 6 -- Acquisitions Murphy Oil Company Ltd. Midstream Operations In May 2001, we closed the acquisition of substantially all of the crude oil pipeline, gathering, storage and terminalling assets of Murphy Oil Company Ltd. for approximately $161 million in cash ("the Murphy Acquisition"), including financing and transaction costs. The purchase included $7.2 million for excess inventory in the pipeline systems. The principal assets acquired include approximately 450 miles of crude oil and condensate transmission mainlines and associated gathering and lateral lines, approximately 1.1 million barrels of crude oil storage and terminalling capacity located primarily in Kerrobert, Saskatchewan, approximately 200,000 barrels of pipeline linefill, an inactive 108-mile mainline system and 121 trailers used primarily for crude oil transportation. We have reactivated the 108-mile mainline system and began shipping volumes in May of 2001. Murphy has agreed to continue to transport production from fields previously delivering crude oil to these pipeline systems, under a new long-term contract. The current volume is approximately 11,000 barrels per day. The pipeline systems transport approximately 200,000 barrels per day of light, medium and heavy crudes, as well as condensate. The Murphy Acquisition has been accounted for using the purchase method of accounting and the purchase price was allocated in accordance with Accounting Principles Board Opinion No. 16, Business Combinations, ("APB 16") as follows (in thousands): Crude oil pipeline, gathering and terminal assets $150,182 Pipeline linefill 7,602 Net working capital items 1,953 Other property and equipment 487 Other assets, including debt issue costs 360 -------- Total $160,584 ======== Pro Forma Results for the Murphy Acquisition The following unaudited pro forma data is presented to show pro forma revenues, net income and basic and diluted net income per limited partner unit for the partnership as if the Murphy Acquisition and the equity offering discussed in Note 3 had occurred on January 1, 2000 (in thousands): 9

In July 2001, we acquired the assets of CANPET Energy Group Inc. ("CANPET"), a Calgary-based Canadian crude oil and liquefied petroleum gas marketing company, for approximately $42.0 million plus excess inventory at the closing date of approximately $25 million. Approximately $24.0 million of the purchase price, plus the excess inventory, was paid in cash at closing and the remainder, which is subject to certain performance standards, will be paid in common units in April 2004 if such standards are met. CANPET activities include gathering approximately 75,000 barrels per day of crude oil and marketing approximately 26,000 barrels per day of natural gas liquids. Tangible assets include a crude oil handling facility, a 130,000-barrel tank facility and working capital of approximately $8.6 million. Financing for the acquisition was provided through borrowings under our bank credit facility. Note 7 -- Credit Agreements In May 2001, we entered into new amended and restated credit facilities that replaced our existing credit facilities. Our credit facilities currently consist of: . a $630.0 million senior secured revolving credit and term loan facility, which is secured by substantially all of our assets. The facility consists of a $500.0 million domestic revolving facility (with a $10.0 million letter of credit sublimit), a $30.0 million Canadian revolving facility (with a $5.0 million letter of credit sublimit) and a $100.0 million term loan. The facility matures, as to the aggregate $530.0 million domestic and Canadian revolver portions, in April, 2005 and, as to the $100.0 million term portion, in May, 2006. On the revolver portions, no principal is scheduled for payment prior to maturity; however, if we issue privately-placed or public debt, the net proceeds of such debt must be used to repay then-outstanding loans under the domestic revolver, and with the repayment and depending on the amount of net proceeds, the domestic revolver commitment will be reduced by 40% to 50% of its original amount. The term portion of this facility has four scheduled annual payments of principal, commencing May 4, 2002, in the respective amounts of 1%, 7%, 8% and 8% of the original term principal amount, with the remaining principal balance scheduled for payment on the stated maturity date of May 5, 2006. If any part of the term portion is prepaid prior to its first anniversary, a 1% premium will be due on that portion. The revolving credit and term loan facility bears interest at our option at either the base rate, as defined, plus an applicable margin, or LIBOR plus an applicable margin, and further, the Canadian revolver may effectively bear interest based upon bankers' acceptance rates. We incur a commitment fee on the unused portion of the revolver portion of this credit facility. . A $200.0 million senior secured letter of credit and borrowing facility, the purpose of which is to provide standby letters of credit to support the purchase and exchange of crude oil and other specified petroleum products for resale and borrowings to finance crude oil inventory and other specified petroleum products that have been hedged against future price risk. The letter of credit facility is secured by substantially all of our assets and has a sublimit for cash borrowings of $100.0 million to purchase crude oil and other petroleum products that have been hedged against future price risk and to fund margin requirements under NYMEX contracts used to facilitate our hedging activities. The letter of credit facility expires in April, 2004. Aggregate availability under the letter of credit facility for direct borrowings and letters of credit is limited to a borrowing base that is determined monthly based on certain of our current assets and current liabilities, primarily inventory and accounts receivable and accounts payable related to the purchase and sale of crude oil and other specified petroleum products. 10

Our credit facilities prohibit distributions on, or purchases or redemptions of, units if any default or event of default is continuing. In addition, the agreements contain various covenants limiting our ability to, among other things: . incur indebtedness; . grant liens; . sell assets; . make investments; . engage in transactions with affiliates; . enter into prohibited contracts; and . enter into a merger or consolidation. Our credit facilities treat a change of control as an event of default and also require us to maintain: . a current ratio (as defined) of 1.0 to 1.0; . a debt coverage ratio which is not greater than 4.75 to 1.0 through September 29, 2001, 4.50 to 1 from September 30, 2001 through June 29, 2002, 4.25 to 1.0 from June 30, 2002 through December 30, 2002 and 4.0 to 1.0 thereafter; . an interest coverage ratio which is not less than 2.75 to 1.0; and . a debt to capital ratio of not greater than 0.73 to 1.0 prior to December 31, 2002 and 0.65 to 1.0 thereafter. A default under our credit facilities would permit the lenders to accelerate the maturity of the outstanding debt and to foreclose on the assets securing the credit facilities. As long as we are in compliance with our commercial credit agreements, they do not restrict our ability to make distributions of "available cash" as defined in our partnership agreement. We are currently in compliance with the covenants contained in our credit agreements. Note 8 -- Distributions On February 14, 2001 we paid a cash distribution of $0.4625 per unit on our outstanding common units, Class B units and subordinated units. The distribution was paid to unitholders of record on February 7, 2001 for the period October 1, 2000 through December 31, 2000. The total distribution paid was approximately $16.3 million, with approximately $7.5 million paid to our public unitholders and the remainder paid to our prior general partner for its limited and general partner interests. The distribution was in excess of the minimum quarterly distribution specified in the Partnership Agreement. On May 15, 2001, we paid a cash distribution of $0.475 per unit on our outstanding common units, Class B units and subordinated units. The distribution was paid to unitholders of record on May 3, 2001 for the period January 1, 2001 through March 31, 2001. The total distribution paid was approximately $16.8 million, with approximately $7.7 million paid to our public unitholders and the remainder to our prior general partner for its limited and general partner interests. On July 24, 2001 we declared a cash distribution of $0.50 per unit on our outstanding common units, Class B units and subordinated units. The distribution is payable on August 14, 2001 to holders of record on August 3, 2001. The total distribution to be paid is approximately $19.9 million, with approximately $13.5 million to be paid to our common unitholders, $0.7 million to our Class B common unitholders, $5.0 million to our subordinated unitholders, and the remainder to be paid to our general partner for its general partner interests. Note 9 -- Operating Segments Our operations consist of two operating segments: (1) Pipeline Operations - engages in interstate and intrastate crude oil pipeline transportation and related merchant activities; and (2) Gathering, Marketing, Terminalling and Storage Operations - engages in purchases and resales of crude oil at various points along the distribution chain and the leasing of terminalling and storage facilities. 11

Note 10 -- Accounting Pronouncements In June 2001, the Financial Accounting Standards Board ("FASB") issued Statements of Financial Accounting Standards No. 141 "Business Combinations" ("SFAS 141") and No. 142 "Goodwill and Other Intangible Assets" ("SFAS 142"). SFAS 141 requires all business combinations initiated after June 30, 2001, to be accounted for under the purchase method. For all business combinations for which the date of acquisition is after June 30, 2001, this Standard also establishes specific criteria for the recognition of intangible assets separately from goodwill and requires unallocated negative goodwill to be written off immediately as an extraordinary gain, rather than deferred and amortized. SFAS 142 changes the accounting for goodwill and other intangible assets after an acquisition. The most significant changes made by SFAS 142 are: 1) goodwill and intangible assets with indefinite lives will no longer be amortized; 2) goodwill and intangible assets with indefinite lives must be tested for impairment at least annually; and 3) the amortization period for intangible assets with finite lives will no longer be limited to forty years. At this time, we cannot reasonably estimate the effect of the adoption of this statement on either our financial position, results of operations, or cash flows. We will account for all future business combinations, including the CANPET acquisition, under SFAS 141. Effective January 1, 2002, we will adopt SFAS 142, as required. At that time, amortization will cease on the unamortized portion of the goodwill arising from the Scurlock acquisition. In June 2001, the FASB also approved for issuance SFAS 143 "Asset Retirement Obligations". SFAS 143 establishes accounting requirements for retirement obligations associated with tangible long-lived assets, including (1) the timing of the liability recognition, (2) initial measurement of the liability, (3) allocation of asset retirement cost to expense, (4) subsequent measurement of the liability and (5) financial statement disclosures. SFAS 143 requires that an asset retirement cost should be capitalized as part of the cost of the related long-lived asset and subsequently allocated to expense using a systematic and rational method. We will adopt the statement effective January 1, 2003, as required. The transition adjustment resulting from the adoption of SFAS 143 will be reported as a cumulative effect of a change in accounting principle. At this time, we cannot reasonably estimate the effect of the adoption of this statement on either our financial position, results of operations, or cash flows. Note 11 -- Contingencies During 1997, the All American Pipeline experienced a leak in a segment of its pipeline in California that resulted in an estimated 12,000 barrels of crude oil being released into the soil. Immediate action was taken to repair the pipeline leak, contain the spill and to recover the released crude oil. We have expended approximately $400,000 to date in connection with this spill. We do not expect additional costs related to this site to exceed $350,000, although we can provide no assurances in that regard. Prior to being acquired by our predecessor in 1996, the Ingleside Terminal experienced releases of refined petroleum products into the soil and groundwater underlying the site due to activities on the property. We are undertaking a voluntary state-administered remediation of the contamination on the property. We have spent approximately $145,000 to date in investigating the contamination at this site. We do not anticipate the total additional costs related to this site to exceed $250,000, although no assurance can be given that the actual cost could not exceed such estimate. In addition, a portion of any such costs may be reimbursed to us from Plains Resources. Litigation Texas Securities Litigation. On November 29, 1999, a class action lawsuit was filed in the United States District Court for the Southern District of Texas entitled Di Giacomo v. Plains All American Pipeline, L.P., et al. The suit alleged that Plains All American and certain of the officers and directors of Plains All American Inc. (our general partner at the time) violated federal securities laws, primarily in connection with unauthorized trading by a former employee. An additional 13

nineteen cases were filed in the Southern District of Texas, some of which name Plains All American Inc. and Plains Resources as additional defendants. All of the federal securities claims have been consolidated into two actions. The first consolidated action is that filed by purchasers of Plains Resources' common stock and options, and is captioned Koplovitz v. Plains Resources Inc., et al. The second consolidated action is that filed by purchasers of our common units, and is captioned Di Giacomo v. Plains All American Pipeline, L.P., et al. Plaintiffs alleged that the defendants were liable for securities fraud violations under Rule 10b-5 and Section 20(a) of the Securities Exchange Act of 1934 and for making false registration statements under Sections 11 and 15 of the Securities Act of 1933. We and Plains Resources reached an agreement with representatives for the plaintiffs for the settlement of all of the class actions, and in January 2001, we deposited approximately $30.0 million under the terms of the settlement agreement. The total cost of the settlement to us and Plains Resources, including interest and expenses and after insurance reimbursements, was $14.9 million. Of that amount, $1.0 million was allocated to Plains Resources by agreement between special independent committees of the board of directors of Plains All American Inc. and the board of directors of Plains Resources. The settlement is subject to final approval by the court. The settlement agreement does not affect the Texas Derivative Litigation and Delaware Derivative Litigation described below. Delaware Derivative Litigation. On December 3, 1999, two derivative lawsuits were filed in the Delaware Chancery Court, New Castle County, entitled Susser v. Plains All American Inc., et al and Senderowitz v. Plains All American Inc., et al. These suits, and three others which were filed in Delaware subsequently, named Plains All American Inc., its directors and certain of its officers as defendants, and allege that the defendants breached the fiduciary duties that they owed to Plains All American Pipeline, L.P. and its unitholders by failing to monitor properly the activities of its employees. The court has consolidated all of the cases under the caption In Re Plains All American Inc. Shareholders Litigation, and has designated the complaint filed in Susser v. Plains All American Inc. as the complaint in the consolidated action. A motion to dismiss was filed on behalf of the defendants on August 11, 2000. The plaintiffs in the Delaware derivative litigation seek that the defendants . account for all losses and damages allegedly sustained by Plains All American from the unauthorized trading losses; . establish and maintain effective internal controls ensuring that our affiliates and persons responsible for our affairs do not engage in wrongful practices detrimental to Plains All American; . pay for the plaintiffs' costs and expenses in the litigation, including reasonable attorneys' fees, accountants' fees and experts' fees; and . provide the plaintiffs any additional relief as may be just and proper under the circumstances. We have reached an agreement in principle with the plaintiffs, subject to approval by the Delaware court, to settle the Delaware litigation for approximately $1.1 million. Texas Derivative Litigation. On July 11, 2000, a derivative lawsuit was filed in the United States District Court of the Southern District of Texas entitled Fernandes v. Plains All American Inc., et al, naming Plains All American Inc., its directors and certain of its officers as defendants. This lawsuit contains the same claims and seeks the same relief as the Delaware derivative litigation, described above. A motion to dismiss was filed on behalf of the defendants on August 14, 2000. We intend to vigorously defend the claims made in the Texas derivative litigation. We believe that Delaware court approval of the settlement of the Delaware derivative litigation will effectively preclude prosecution of the Texas derivative litigation. However, there can be no assurance that we will be successful in our defense or that this lawsuit will not have a material adverse effect on our financial condition, results of operation, or cash flows. We, in the ordinary course of business, are a claimant and/or a defendant in various other legal proceedings. Management does not believe that the outcome of these other legal proceedings, individually and in the aggregate, will have a materially adverse effect on our financial condition, results of operations or cash flows. 14

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Overview We are a Delaware limited partnership that was formed in September of 1998 to acquire and operate the midstream crude oil business and assets of Plains Resources Inc. and its wholly owned subsidiaries. On November 23, 1998, we completed our initial public offering and the transactions whereby we became the successor to the business of the midstream subsidiaries of Plains Resources. Our operations are conducted through Plains Marketing, L.P., All American Pipeline, L.P. and Plains Marketing Canada, L.P. We are engaged in interstate and intrastate transportation marketing, and terminalling of crude oil. Our operations are conducted primarily in Texas, California, Oklahoma, Louisiana, the Gulf of Mexico and the Canadian Provinces of Alberta and Saskatchewan. Pipeline Operations. Our activities from pipeline operations generally consist of transporting third-party volumes of crude oil for a tariff and merchant activities designed to capture price differentials between the cost to purchase and transport crude oil to a sales point and the price received for such crude oil at the sales point. Tariffs on our pipeline systems vary by receipt point and delivery point. The gross margin generated by our tariff activities depends on the volumes transported on the pipeline and the level of the tariff charged, as well as the fixed and variable costs of operating the pipeline. Our ability to generate a profit on margin activities is not tied to the absolute level of crude oil prices but is generated by the difference between an index-related price paid and other costs incurred in the purchase of crude oil and an index-related price at which we sell crude oil. We are well positioned to take advantage of these price differentials due to our ability to move purchased volumes on our pipeline systems. We combine reporting of gross margin for tariff activities and margin activities due to the sharing of fixed costs between the two activities. Terminalling and Storage Activities and Gathering and Marketing Activities. Gross margin from terminalling and storage activities is dependent on the throughput volume of crude oil stored and the level of fees generated at our terminalling and storage facilities. Gross margin from our gathering and marketing activities is dependent on our ability to sell crude oil at a price in excess of our aggregate cost. These operations are not directly affected by the absolute level of crude oil prices, but are affected by overall levels of supply and demand for crude oil and fluctuations in market related indices. Recent Events Strategic Transaction Involving General Partner. On June 8, 2001, Plains All American Inc., our former general partner and a wholly owned subsidiary of Plains Resources Inc., sold a portion of its ownership in our partnership to an investor group including, among others, affiliates of Kayne Anderson Capital Advisors, EnCap Investments, Strome Investment Management, James C. Flores and our current management for aggregate consideration of approximately $155.2 million. In connection with this transaction, a new entity jointly owned by the investor group and Plains Resources Inc. became our general partner and assumed all of the general partner's rights and obligations under our partnership agreement. The investor group purchased approximately 5.2 million subordinated units from an affiliate of Plains Resources Inc. As a result of this transaction and our recent equity offering, Plains Resources' effective ownership in us has been reduced to approximately 33% from approximately 54%. Plains Resources has agreed to make available for sale to our management group an additional 2% of the general partner interest on substantially the same terms as the other investors. Murphy Oil Company Ltd. Midstream Operations. In May 2001, we closed the acquisition of substantially all of the crude oil pipeline, gathering, storage and terminalling assets of Murphy Oil Company Ltd. for approximately $161 million in cash (the "Murphy Acquisition"), including financing and transaction costs. The purchase included $7.2 million for excess inventory in the pipeline systems. The principal assets acquired include approximately 450 miles of crude oil and condensate transmission mainlines and associated gathering and lateral lines, approximately 1.1 million barrels of crude oil storage and terminalling capacity located primarily in Kerrobert, Saskatchewan, approximately 200,000 barrels of linefill, an inactive 108-mile mainline system and 121 trailers used primarily for crude oil transportation. We have reactivated the 108-mile mainline system and began shipping volumes in May of 2001. Murphy has agreed to continue to transport production from fields currently delivering crude oil to these pipeline systems, under a new long-term contract. The current volume is approximately 11,000 barrels per day. The pipeline systems transport approximately 200,000 barrels per day of light, medium and heavy crudes, as well as condensate. 15

CANPET Energy Group Inc. In July 2001, we acquired the assets of CANPET Energy Group Inc. ("CANPET") a Calgary based Canadian crude oil and liquefied petroleum gas marketing company, for approximately $42.0 million plus excess inventory at the closing date of approximately $25 million. Approximately $24.0 million of the purchase price, plus the excess inventory, was paid in cash at closing and the remainder which is subject to certain performance standards will be paid in common units in April, 2004, if such standards are met. CANPET activities include gathering approximately 75,000 barrels per day of crude oil and marketing approximately 26,000 barrels per day of natural gas liquids. Tangible assets include a crude oil handling facility, a 130,000-barrel tank facility and working capital of approximately $8.6 million. Financing for the acquisition was provided through borrowings under our bank credit facility. Results of Operations Three Months Ended June 30, 2001 and 2000 For the three months ended June 30, 2001, we reported net income of $7.1 million on total revenue of $1.6 billion compared to net income for the same period in 2000 of $6.1 million on total revenues of $1.5 billion. The results for the three months ended June 30, 2001 and 2000 include the following unusual items: 2001 . a $6.0 million charge associated with the vesting of phantom partnership units as a result of the sale by our former general partner of a portion of its general partner interest. $5.6 million of the charge was noncash and was satisfied by units owned by our former general partner. This portion of the charge had no impact on equity or the number of outstanding units as it was offset by a deemed capital contribution by our former general partner and the units were satisfied by units owned by our former general partner. 2000 . an extraordinary loss of $11.0 million related to the refinancing of our credit agreements, and . $2.9 million of previously deferred gains on interest rate swap terminations recognized due to the early extinguishment of debt. Excluding these unusual items, we would have reported net income of $13.1 million and $14.2 million for the three months ended June 30, 2001 and 2000, respectively. The following table sets forth our operating results for the periods indicated and includes the impact of these unusual items discussed above (in thousands) (unaudited): 16

THREE MONTHS ENDED JUNE 30, --------------------- 2001 2000 ---- ---- OPERATING RESULTS: Revenues $ 1,586,617 $ 1,481,834 =========== =========== Gross margin: Pipeline $ 18,699 $ 12,759 Gathering and marketing and terminalling and storage 17,688 20,015 ----------- ----------- Total 36,387 32,774 General and administrative expense (15,041) (7,949) ----------- ----------- Gross profit $ 21,346 $ 24,825 =========== =========== Net income $ 7,067 $ 6,061 =========== =========== AVERAGE DAILY VOLUMES (BARRELS): Pipeline Activities: All American Tariff activities 68 74 Margin activities 56 57 Canada 210 - Other 152 118 ----------- ----------- Total 486 249 =========== =========== Lease gathering 322 237 Bulk purchases 17 26 ----------- ----------- Total 339 263 =========== =========== Terminal throughput 151 61 =========== =========== Storage leased to third parties, monthly average volumes 2,427 1,953 =========== =========== Revenues. Revenues increased to $1.59 billion for the second quarter of 2001 compared to the 2000 second quarter amount of $1.48 billion. The increase is primarily attributable to the Murphy Acquisition. The impact on revenues from the increase in volumes from the Murphy Acquisition, as well as the increase in our domestic lease volumes, were offset by lower crude oil prices. Cost of Sales and Operations. Cost of sales and operations increased to $1.55 billion in the second quarter of 2001 compared to $1.45 billion in the same quarter of 2000, primarily due to the reasons discussed above under "Revenues". General and Administrative. General and administrative expenses were $15.0 million for the quarter ended June 30, 2001, compared to $7.9 million for the second quarter in 2000. The increase in 2001 is predominantly due to a $5.6 million noncash charge and $0.4 million cash charge related to the vesting of phantom partnership units, as well as expenses incurred as a result of the Murphy Acquisition. Depreciation and Amortization. Depreciation and amortization expense was $6.5 million for the quarter ended June 30, 2001, compared to $4.7 million for the second quarter of 2000. The majority of this increase is due to the Murphy Acquisition. Interest expense. Interest expense was $8.1 million for the quarter ended June 30, 2001, compared to $6.2 million for the 2000 quarter. The increase is primarily due to the increase in debt levels in the second quarter as a result of the net effect of the Murphy Acquisition and the proceeds from the issuance of common units as well as lower interest rates. Interest expense was approximately $6.6 million in the first quarter of 2001. Early extinguishment of debt. During the quarter ended June 30, 2000, we recognized an extraordinary loss, consisting primarily of unamortized debt issue costs totaling $11.0 related to the refinancing or our credit facilities. In addition, interest and other income for the second quarter 2000 includes $2.9 million of previously deferred gains from terminated interest rate swaps as a result of the debt extinguishment. 17

Segment Results Pipeline Operations. Gross margin from pipeline operations increased 47% to $18.7 million for the quarter ended June 30, 2001 from $12.8 million for the prior year quarter. Increased margins from the Murphy Acquisition, a 10% increase in the tariff rate on the All American Pipeline, as well as increased volumes on the Scurlock and West Texas gathering systems were all contributing factors in the increase. These increases were partially offset by increased fuel and power expenses. Average daily volumes on our pipelines during the second quarter of this year were 486,000 barrels per day compared to 249,000 barrels per day last year. The 237,000 barrel per day increase includes increases of 210,000 barrels per day due to the Murphy Acquisition and 27,000 barrels per day on our existing pipeline systems. Tariff transport volumes on the All American Pipeline decreased from an average of 74,000 barrels per day for the quarter ended June 30, 2000 to 68,000 barrels per day in the comparable quarter of 2001, due to a decrease in shipments of offshore California production. Gathering and Marketing Activities and Terminalling and Storage Activities. Gross margin from gathering, marketing, terminalling and storage activities was approximately $17.7 million for the quarter ended June 30, 2001 compared to $20.0 million in the prior year quarter. This decrease is due to tightened margins as a result of a contango market as well as increased operating costs related to higher fuel and power costs. Incremental margins from the Murphy Acquisition partially offset the decreases discussed above. Total gathering volumes increased from an average of 263,000 barrels per day in the second quarter of 2000 to approximately 339,000 barrels per day in the current year period. Approximately half of this increase is due to the Murphy Acquisition with the remainder coming from an acquisition of certain facilities from Placid Oil Company in December 2000, as well as increases from our existing domestic business units. Terminal throughput averaged approximately 151,000 barrels per day and 61,000 barrels per day in the first quarter of 2001 and 2000, respectively, primarily due to throughput arrangements with refiners and the existence of a contango market. Six Months Ended June 30, 2001 and 2000 For the six months ended June 30, 2001, we reported net income of $20.1 million on total revenue of $3.1 billion, compared to a net income for the same period in 2000 of $66.2 million on total revenues of $3.5 billion. The results for the six months ended June 30, 2001 and 2000 include the following unusual items: 2001 . a $6.1 million charge associated with the vesting of phantom partnership units primarily as a result of the sale by our former general partner of a portion of its general partner interest. $5.7 million of the charge was noncash and was satisfied by units owned by our former general partner. This portion of the charge had no impact on equity or the number of outstanding units as it was offset by a deemed capital contribution by our former general partner and the units were satisfied by units owned by our former general partner, and . $0.5 million cumulative effect gain as a result of the adoption of Statement of Financial Accounting Standards No. 133, "Accounting for Derivative Instruments and Hedging Activities" ("SFAS 133"). 2000 . a $28.1 million gain on the sale of crude oil linefill; . a $20.1 million gain on the sale of the segment of the All American Pipeline that extends from Emidio, California, to McCamey, Texas; . $9.7 million of previously deferred gains on interest rate swap terminations recognized due to the early extinguishment of debt; . an extraordinary loss of $15.1 million related to the early extinguishment of debt, and . amortization of $4.6 million of debt issue costs associated with facilities put in place during the fourth quarter of 1999. Excluding these unusual items, we would have reported net income of $25.7 million and $28.1 million for the six months ended June 30, 2001 and 2000, respectively. The following table sets forth our operating results for the periods indicated and includes the impact of the unusual items discussed above (in thousands) (unaudited): 18

SIX MONTHS ENDED JUNE 30, 2001 2000 --------------------- OPERATING RESULTS: Revenues $ 3,106,741 $ 3,484,341 =========== =========== Gross margin: Pipeline $ 32,591 $ 25,914 Gathering and marketing and terminalling and storage 36,526 43,412 ----------- ----------- Total 69,117 69,326 General and administrative expense (24,030) (16,575) ----------- ----------- Gross profit $ 45,087 $ 52,751 =========== =========== Net income $ 20,082 $ 66,216 =========== =========== SIX MONTHS ENDED JUNE 30, 2001 2000 ---- ---- AVERAGE DAILY VOLUMES (BARRELS): Pipeline Activities: All American Tariff activities 69 73 Margin activities 61 58 Canada(1) 210 - Other 157 116 ----- ----- Total 497 247 ===== ===== Lease gathering 324 247 Bulk purchases 19 28 ----- ----- Total 343 275 ===== ===== Terminal throughput 143 55 ===== ===== Storage leased to third parties, monthly average volumes 2,165 1,387 ===== ===== - -------- (1) Represents average daily volumes from the effective date, April 1, 2001. Revenues. Revenues decreased to $3.11 billion from $3.48 billion in the first half of 2000. The decrease is primarily attributable to lower crude oil prices, offset somewhat by higher pipeline and gathering volumes, primarily attributable to the Murphy Acquisition. Cost of Sales and Operations. Cost of sales and operations decreased to $3.04 billion from $3.42 billion in the first half of 2000, primarily due to the reasons discussed above under "Revenues". General and Administrative. General and administrative expenses were $24.0 million for the six months ended June 30, 2001, compared to $16.6 million for the same period in 2000. The increase in 2001 is primarily due to a $6.1 million charge attributable to the vesting of phantom partnership units in the second quarter as a result of the sale by our former general partner of a portion of its general partner interest. $5.7 million of the charge was noncash and was satisfied by units owned by our former general partner. This portion of the charge had no impact on partner's capital or the number of outstanding units as it was offset by a deemed capital contribution by our former general partner. Depreciation and Amortization. Depreciation and amortization expense was $11.2 million for the six months ended June 30, 2001, compared to $14.8 million for the first half of 2000. The decrease is primarily due to the increased amortization of debt issue costs in the 2000 period associated with facilities put in place during the fourth quarter of 1999 as a result of the unauthorized trading losses and somewhat offset in the current year period by the depreciation attributable to the Murphy Acquisition. 19

Interest expense. Interest expense was $14.7 million for the six months ended June 30, 2001, compared to $15.3 million for the same period in 2000. The decrease is due to a lower average debt balance as well as lower interest rates. Gain on sale of linefill. We initiated the sale of 5.2 million barrels of crude oil linefill from the All American Pipeline in November 1999. The sale was completed in March 2000. We recognized a gain of $28.1 million in connection with the sale of the linefill in the first quarter of 2000. Gain on sale of pipeline segment. On March 24, 2000, we completed the sale of the segment of the All American Pipeline that extends from Emidio, California to McCamey, Texas to a unit of El Paso Energy Corporation for proceeds of approximately $124.0 million, which are net of associated transaction costs and estimated costs to remove certain equipment. We recognized a total gain of $20.1 million in connection with the sale in the first quarter of 2000. Early extinguishment of debt. During the six months ended June 30, 2000, we recognized extraordinary losses, consisting primarily of unamortized debt issue costs, totaling $15.1 million related to the permanent reduction of the All American Pipeline, L.P. term loan facility and the refinancing of our credit facilities. In addition, interest and other income for the six months ended June 30, 2000, includes $9.7 million of previously deferred gains from terminated interest rate swaps as a result of the debt extinguishments. Cumulative effect of accounting change. During the first quarter of 2001, we recognized a $0.5 million cumulative effect gain as a result of the adoption of SFAS 133 effective January 1, 2001. Segment Results Pipeline Operations. Gross margin from pipeline operations increased to $32.6 million for the six months ended June 30, 2001 compared to $25.9 million for the prior year period. Increased margins from the Murphy Acquisition, a 10% increase in the tariff rate on the All American Pipeline, as well as increased volumes on the Scurlock gathering systems were all contributing factors in the increase. Average daily volumes on our pipelines during the first half of this year were 497,000 barrels per day compared to 247,000 barrels per day last year. The 250,000 barrel per day increase includes increases of 210,000 barrels per day due to the Murphy Acquisition and 40,000 barrels per day on our existing pipeline systems. Tariff transport volumes on the All American Pipeline decreased from an average of 73,000 barrels per day for the six months ended June 30, 2000 to 69,000 barrels per day in the comparable period of 2001, primarily due to a decrease in shipments of offshore California production. Gathering and Marketing Activities and Terminalling and Storage Activities. Gross margin from gathering, marketing, terminalling and storage activities was approximately $36.5 million for the six months ended June 30, 2001 compared to $43.4 million in the prior year period. This decrease is due to tightened margins as a result of a contango crude market as well as increased operating costs related to higher fuel and power costs. Incremental margins from the Murphy Acquisition partially offset the decreases discussed above. Total gathering volumes increased from an average of 275,000 barrels per day in the first half of 2000 to approximately 343,000 barrels per day in the current year period. Approximately half of this increase is due to the Murphy Acquisition with the remainder coming from an acquisition of certain facilities from Placid Oil Company in December 2000, as well as our existing domestic business units. Terminal throughput averaged approximately 143,000 barrels per day and 55,000 barrels per day in the first half of 2001 and 2000, respectively, primarily due to throughput arrangements with refiners and the existence of a contango market. Liquidity and Capital Resources Credit Agreements In May 2001, we entered into new amended and restated credit facilities that replaced our existing credit facilities. Our $500.0 million senior secured revolving credit facility was replaced by a $630.0 million senior secured revolving credit and term loan facility, which is secured by substantially all of our assets. The facility consists of a $500.0 million domestic revolving facility (with a $10.0 million letter of credit sublimit), a $30.0 million Canadian revolving facility (with a $5.0 million letter of credit sublimit) and a $100.0 million term loan. The facility matures, as to the aggregate $530.0 million domestic and Canadian revolver portions, in April, 2005 and, as to the $100.0 million term portion, in May, 2006. We also amended our $200 million senior secured letter of credit and borrowing facility. For a complete discussion of our credit facilities, see Note 7 to the Consolidated Financial Statements. 20

Liquidity Cash generated from operations and our credit facilities are our primary sources of liquidity. At June 30, 2001, we had working capital of approximately $28.6 million. On August 8, 2001, subsequent to the closing of the CANPET acquisition, PAA had approximately $439.8 million outstanding under its $630 million of credit facilities (excluding the letter of credit and borrowing facility). Accordingly, PAA can borrow up to an additional $190 million subject to covenants contained in the agreement. We believe that we have sufficient liquid assets, cash from operations and borrowing capacity under our credit agreements to meet our financial commitments, debt service obligations, contingencies and anticipated capital expenditures. Cash Flows SIX MONTHS ENDED JUNE 30, ------------------ (IN MILLIONS) (UNAUDITED) 2001 2000 - ------------------------ ---- ---- Cash provided by (used in): Operating activities $ (47.0) $ (6.4) Investing activities (168.9) 218.3 Financing activities 213.5 (264.1) Operating Activities. Net cash used in operating activities for the first half of 2001 resulted primarily from purchases of hedged inventory maintained in storage until delivery due to the existence of a contango market. All of this inventory was hedged for delivery in the third quarter. Investing Activities. Net cash used for investing activities for the first half of 2001 included approximately $161 million for the Murphy Acquisition. Financing activities. Cash provided by financing activities for the first half of 2001 resulted from our credit facilities that were used to finance the Murphy Acquisition and the issuance of additional units which raised approximately $100.7 million of equity capital. Proceeds from the equity offering were used to repay indebtedness under the credit facilities. Contingencies Following our announcement in November 1999 of our losses resulting from unauthorized trading by a former employee, numerous class action lawsuits were filed in the United States District Court of the Southern District of Texas against us, certain of our general partner's officers and directors and in some of these cases, our general partner and Plains Resources Inc. alleging violations of the federal securities laws. In addition, derivative lawsuits were filed in the Delaware Chancery Court and the United States District Court of the Southern District of Texas against our general partner, its directors and certain of its officers alleging the defendants breached the fiduciary duties owed to us and our unitholders by failing to monitor properly the activities of our traders. The class actions and the Delaware derivative suits have been settled, subject to court approval. See Part II, Item 1 - "Legal Proceedings". We may experience future releases of crude oil into the environment from our pipeline and storage operations, or discover releases that were previously unidentified. Although we maintain an extensive inspection program designed to prevent and, as applicable, to detect and address such releases promptly, damages and liabilities incurred due to any future environmental releases from our assets may substantially affect our business. Accounting Pronouncements In June 2001, the Financial Accounting Standards Board ("FASB") issued Statements of Financial Accounting Standards No. 141 "Business Combinations" ("SFAS 141") and No. 142 "Goodwill and Other Intangible Assets" ("SFAS 142"). SFAS 141 requires all business combinations initiated after June 30, 2001, to be accounted for under the purchase method. For all business combinations for which the date of acquisition is after June 30, 2001, this Standard also establishes specific criteria for the recognition of intangible assets separately from goodwill and requires unallocated negative goodwill to be written off immediately as an extraordinary gain, rather than deferred and amortized. SFAS 142 changes the accounting for goodwill and other intangible assets after an acquisition. The most significant changes made by SFAS 142 are: 1) goodwill and intangible assets with indefinite lives will no longer be amortized; 2) goodwill and intangible assets with indefinite lives must 21

be tested for impairment at least annually; and 3) the amortization period for intangible assets with finite lives will no longer be limited to forty years. At this time, we cannot reasonably estimate the effect of the adoption of this statement on either our financial position, results of operations, or cash flows. We will account for all future business combinations, including the CANPET acquisition, under SFAS 141. Effective January 1, 2002, we will adopt SFAS 142, as required. At that time, amortization will cease on the unamortized portion of the goodwill arising from the Scurlock acquisition. In June 2001, the FASB also approved for issuance SFAS 143 "Asset Retirement Obligations". SFAS 143 establishes accounting requirements for retirement obligations associated with tangible long-lived assets, including (1) the timing of the liability recognition, (2) initial measurement of the liability, (3) allocation of asset retirement cost to expense, (4) subsequent measurement of the liability and (5) financial statement disclosures. SFAS 143 requires that an asset retirement cost should be capitalized as part of the cost of the related long-lived asset and subsequently allocated to expense using a systematic and rational method. We will adopt the statement effective January 1, 2003, as required. The transition adjustment resulting from the adoption of SFAS 143 will be reported as a cumulative effect of a change in accounting principle. At this time, we cannot reasonably estimate the effect of the adoption of this statement on either our financial position, results of operations, or cash flows. Forward-Looking Statements and Associated Risks All statements, other than statements of historical fact, included in this report are forward-looking statements, including, but not limited to, statements identified by the words "anticipate," "believe," "estimate," "expect," "plan," "intend" and "forecast" and similar expressions and statements regarding our business strategy, plans and objectives of our management for future operations. These statements reflect our current views and those of our general partner with respect to future events, based on what we believe are reasonable assumptions. These statements, however, are subject to certain risks, uncertainties and assumptions, including, but not limited to: . the availability of adequate supplies of and demand for crude oil in the areas in which we operate; . the impact of crude oil price fluctuations; successful third-party drilling efforts and completion of announced oil-sands project ; . the effects of competition; . the success of our risk management activities; . the availability of favorable acquisition or combination opportunities; our ability to receive credit on satisfactory terms . unanticipated shortages or cost increases of power supplies, materials or labor . weather interference with business operations or project construction . successful integration and future performance of recently acquired assets; . the impact of current and future laws and governmental regulations; . environmental liabilities not covered by indemnity or insurance; and . general economic, market or business conditions. If one or more of these risks or uncertainties materialize, or if underlying assumptions prove incorrect, actual results may vary materially from the results anticipated in the forward-looking statements. Except as required by applicable securities laws, we do not intend to update these forward-looking statements and information. 22

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS We are exposed to various market risks, including volatility in crude oil commodity prices and interest rates. To manage such exposure, we monitor our inventory levels and our expectations of future commodity prices and interest rates when making decisions with respect to risk management. We do not enter into derivative transactions for speculative trading purposes that would expose us to price risk. Substantially all of our derivative contracts are exchanged or traded with major financial institutions and the risk of credit loss is considered remote. On January 1, 2001, we adopted SFAS 133 "Accounting for Derivative Instruments and Hedging Activities" as amended by SFAS 137 and SFAS 138. Under SFAS 133, all derivative instruments are recorded on the balance sheet at fair value. If the derivative does not qualify as a hedge or is not designated as a hedge, the gain or loss on the derivative is recognized currently in earnings. To qualify for hedge accounting, the derivative must qualify either as a fair value hedge, cash flow hedge or foreign currency hedge. As of June 30, 2001, our transactions consisted of only cash flow and foreign currency hedges (which are defined as fair value hedges) and the remaining discussion will relate exclusively to these types of derivative instruments. If the derivative qualifies for cash flow hedge accounting, the gain or loss on the derivative is deferred in accumulated Other Comprehensive Income ("OCI"), a component of Partners' Capital, to the extent the hedge is effective. Fair value hedge gains or losses are taken directly to earnings in the current period. We utilize various derivative instruments, for purposes other than trading, to hedge our exposure to price fluctuations on crude in storage and expected purchases, sales and transportation of crude oil. The derivative instruments consist primarily of futures and option contracts traded on the New York Mercantile Exchange. We also utilize interest rate collars to manage the interest rate exposure on our long-term debt and foreign currency hedges to manage exchange rate exposure. At June 30, 2001, a $5.8 million unrealized loss was recorded to OCI together with related assets and liabilities of $6.9 million and $12.9 million, respectively. Earnings included a noncash gain of $0.2 million related to the ineffective portion of our cash flow hedges as well as the gain/loss on our fair value hedges, (included in revenues in the income statement). Our hedge- related assets and liabilities are included in other current assets and other current liabilities in the balance sheet. As of June 30, 2001, the total amount of deferred net losses on derivative instruments recorded in OCI are expected to be reclassified to earnings during the next twelve-month period. At June 30, 2001 we had the following open crude oil hedge positions: 2001 2002 ------------------ ------------------- 3rd Qtr 4th Qtr 1st Qtr 2nd Qtr ------- ------- ------- ------- Volume (bbls) Short positions 812,000 - - - Long positions - 762,000 132,000 250,000 Average price ($/bbl) $25.13 $26.84 $27.28 $25.56 At June 30, 2001, we had an interest rate collar arrangement to protect interest rate fluctuations on a portion of our outstanding debt for an aggregate notional principal amount of $125.0 million. This instrument is based on LIBOR rates and provides for a floor of 6.1% and a ceiling of 8.0% with an expiration date of August 2002. We formally document all relationships between hedging instruments and hedged items, as well as our risk management objectives and strategy for undertaking the hedge. Hedge effectiveness is measured on a quarterly basis. This process includes specific identification of the hedging instrument and the hedge transaction, the nature of the risk being hedged and how the hedging instrument's effectiveness will be assessed. Both at the inception of the hedge and on an ongoing basis, we assess whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows of hedged items. No amounts were excluded from the computation of hedge effectiveness. 23

PART II. OTHER INFORMATION Items 1. LEGAL PROCEEDINGS Texas Securities Litigation. On November 29, 1999, a class action lawsuit was filed in the United States District Court for the Southern District of Texas entitled Di Giacomo v. Plains All American Pipeline, L.P., et al. The suit alleged that Plains All American and certain of the officers and directors of Plains All American Inc. (our general partner at the time) violated federal securities laws, primarily in connection with unauthorized trading by a former employee. An additional nineteen cases were filed in the Southern District of Texas, some of which name Plains All American Inc. and Plains Resources as additional defendants. All of the federal securities claims have been consolidated into two actions. The first consolidated action is that filed by purchasers of Plains Resources' common stock and options, and is captioned Koplovitz v. Plains Resources Inc., et al. The second consolidated action is that filed by purchasers of our common units, and is captioned Di Giacomo v. Plains All American Pipeline, L.P., et al. Plaintiffs alleged that the defendants were liable for securities fraud violations under Rule 10b-5 and Section 20(a) of the Securities Exchange Act of 1934 and for making false registration statements under Sections 11 and 15 of the Securities Act of 1933. We and Plains Resources reached an agreement with representatives for the plaintiffs for the settlement of all of the class actions, and in January 2001, we deposited approximately $30.0 million under the terms of the settlement agreement. The total cost of the settlement to us and Plains Resources, including interest and expenses and after insurance reimbursements, was $14.9 million. Of that amount, $1.0 million was allocated to Plains Resources by agreement between special independent committees of the board of directors of Plains All American Inc. and the board of directors of Plains Resources. The settlement is subject to final approval by the court. The settlement agreement does not affect the Texas Derivative Litigation and Delaware Derivative Litigation described below. Delaware Derivative Litigation. On December 3, 1999, two derivative lawsuits were filed in the Delaware Chancery Court, New Castle County, entitled Susser v. Plains All American Inc., et al and Senderowitz v. Plains All American Inc., et al. These suits, and three others which were filed in Delaware subsequently, named Plains All American Inc., its directors and certain of its officers as defendants, and allege that the defendants breached the fiduciary duties that they owed to Plains All American Pipeline, L.P. and its unitholders by failing to monitor properly the activities of its employees. The court has consolidated all of the cases under the caption In Re Plains All American Inc. Shareholders Litigation, and has designated the complaint filed in Susser v. Plains All American Inc. as the complaint in the consolidated action. A motion to dismiss was filed on behalf of the defendants on August 11, 2000. The plaintiffs in the Delaware derivative litigation seek that the defendants . account for all losses and damages allegedly sustained by Plains All American from the unauthorized trading losses; . establish and maintain effective internal controls ensuring that our affiliates and persons responsible for our affairs do not engage in wrongful practices detrimental to Plains All American; . pay for the plaintiffs' costs and expenses in the litigation, including reasonable attorneys' fees, accountants' fees and experts' fees; and . provide the plaintiffs any additional relief as may be just and proper under the circumstances. We have reached an agreement in principle with the plaintiffs, subject to approval by the Delaware court, to settle the Delaware litigation for approximately $1.1 million. Texas Derivative Litigation. On July 11, 2000, a derivative lawsuit was filed in the United States District Court of the Southern District of Texas entitled Fernandes v. Plains All American Inc., et al, naming Plains All American Inc., its directors and certain of its officers as defendants. This lawsuit contains the same claims and seeks the same relief as the Delaware derivative litigation, described above. A motion to dismiss was filed on behalf of the defendants on August 14, 2000. We intend to vigorously defend the claims made in the Texas derivative litigation. We believe that Delaware court approval of the settlement of the Delaware derivative litigation will effectively preclude prosecution of the Texas derivative litigation. However, there can be no assurance that we will be successful in our defense or that this lawsuit will not have a material adverse effect on our financial position or results of operation. We, in the ordinary course of business, are a claimant and/or a defendant in various other legal proceedings. Management does not believe that the outcome of these other legal proceedings, individually and in the aggregate, will have a materially adverse effect on our financial condition, results of operations or cash flows. 24

Lenders hereby consent to any such restructuring prior to the effectiveness of this Amendment and waive any Change of Control and Event of Default under Section 8.1(k) of the Original Agreement caused thereby. ARTICLE III. -- Conditions of Effectiveness (S) 3.1. Effective Date.

(c) The execution and delivery by each Restricted Person of this Amendment and each other Amendment Document, to the extent a party thereto, the performance by each Restricted Person of its respective obligations hereunder and thereunder, and the consummation of the transactions contemplated hereby and thereby, do not and will not conflict with any provision of any Law or of the organizational documents of any Restricted Person, or of any material agreement, judgment, license, order or permit applicable to or binding upon any Restricted Person, or result in the creation of any Lien upon any assets or properties of any Restricted Person, except in favor of Administrative Agent for the benefit of Lenders and other Permitted Liens. Except for those which have been duly obtained, no consent, approval, authorization or order of any Tribunal or third party is required in connection with the execution and delivery by any Restricted Person of this Amendment or any other Amendment Document, or to consummate the transactions contemplated hereby and thereby.

Each Restricted Person hereby re-pledges, re- grants and re-assigns a security interest in and lien on every asset of the such Restricted Person described as Collateral in any Security Document and re- guarantees all Obligations, as amended hereby. (S) 5.3. Ratification of Intercreditor Agreement. Each Lender hereby acknowledges and confirms that all Obligations under the Credit Agreement, as amended hereby, and the "Obligations" under the Marketing Credit Agreement, as amended on the date hereof, shall be and shall remain subject to the terms and entitled to the benefits of the Intercreditor Agreement. (S) 5.4. Survival of Agreements. All representations, warranties, covenants and agreements of the Restricted Persons herein shall survive the execution and delivery of this Amendment and the performance hereof, including without limitation the making or granting of each Loan, and shall further survive until all of the Obligations are paid in full.

Lenders hereby consent to any such restructuring prior to the effectiveness of this Amendment and waive any Change of Control and Event of Default under Section 8.1(k) of the Original Agreement caused thereby.
