ITEM 2. ACQUISITION OF ASSETS Description of Transaction On May 12, 1999, Plains Scurlock Permian, L.P. ("Plains Scurlock"), a newly formed operating limited partnership of Plains All American Pipeline, L.P., ("PAA"), completed the acquisition of Scurlock Permian LLC and certain other pipeline assets from Marathon Ashland Petroleum LLC (the "Scurlock Acquisition"). Including working capital adjustments and associated closing and financing costs, the cash purchase price paid at closing was approximately $146 million. Financing for the Scurlock Acquisition was provided through (i) Plains Scurlock's limited recourse bank facility with BankBoston, N.A. (the "Plains Scurlock Credit Facility"), (ii) the sale to the General Partner of 1.3 million Class B Common Units of PAA at $19.125 per unit, the price equal to the market value of PAA's common units and (iii) a $25 million draw under its existing revolving credit agreement. The Plains Scurlock Credit Facility consists of (i) a five-year $130 million term loan and (ii) a three-year $35 million revolving credit facility. The Plains Scurlock Credit Facility is nonrecourse to PAA, and its other operating limited partnerships, Plains Marketing, L.P. and All American Pipeline, L.P., and is secured by the assets acquired by Plains Scurlock. Borrowings under the term loan bear interest at LIBOR plus 3% and under the revolving credit facility at LIBOR plus 2.75%. A commitment fee equal to one- half of one percent per year is charged on the unused portion of the revolving credit facility. The term loan matures in May 2004 and the revolving credit facility matures in May 2002. No principal payment is scheduled for amortization prior to maturity. It is anticipated that the Plains Scurlock Credit Facility will also be used to finance Plains Scurlock's acquisition of the West Texas Gathering System from Chevron Pipe Line Company under a recently announced agreement. Description of Assets Involved Scurlock Permian LLC is engaged in crude oil transportation, trading and marketing, operating in 14 states with more than 2,400 miles of active pipelines, numerous storage terminals and a fleet of more than 225 trucks. Its most significant asset is an 800-mile pipeline and gathering system located in the Spraberry Trend in West Texas that extends into Andrews, Glasscock, Martin, Midland, Regan and Upton Counties, Texas. The assets acquired also include approximately 2.4 million barrels of crude oil, of which approximately 1.4 million barrels are used for working inventory. ITEM 7.

SCURLOCK PERMIAN BUSINESSES NOTES TO INTERIM FINANCIAL STATEMENTS FOR THE THREE MONTHS ENDED MARCH 31, 1999 (UNAUDITED) 1. Scurlock Permian LLC (SPLLC) is a wholly owned subsidiary of Marathon Ashland Petroleum LLC (MAP). MAP was formed effective January 1, 1998, and is owned 62% by Marathon Oil Company (Marathon) and 38% by Ashland Inc. (Ashland). On March 17, 1999, MAP entered into an agreement with Plains Marketing, L.P. (Plains) providing for the sale of MAP's membership interest in SPLLC and certain other pipeline assets (collectively, the Scurlock Permian Businesses or the Company) to Plains. This transaction was consummated on May 12, 1999. The accompanying financial statements do not include any adjustments that might result from the sale. The accompanying financial statements pertain to the businesses that were sold to Plains and represent a carve-out financial statement presentation of a MAP operating unit as of and for the three months ended March 31, 1999 and 1998. The financial statements include allocations and estimates of direct and indirect MAP corporate administrative costs attributable to the Company. The methods by which such amounts are attributed or allocated are deemed reasonable by MAP's management. The financial information herein is not necessarily indicative of the financial position, results of operations and cash flows that would have been reported if the Company had operated as an unaffiliated enterprise, nor is it indicative of future results. In connection with the formation of MAP, Marathon acquired certain refining, marketing and transportation net assets, including the operations comprising SPLLC, from Ashland in exchange for a 38% interest in MAP. The acquisition of Ashland's net assets was accounted for under the purchase method of accounting. The Company is an independent gatherer and marketer of crude oil in the United States, operating in 14 states. Major operations consist of pipeline, barge and truck operations. The pipeline component owns and operates more than 2,400 miles of active pipelines that transport crude oil from leases and unloading stations to major pipeline connections and terminals. The barge facilities consist of eight owned barge terminals located in Louisiana and Texas. The truck operations consist of a fleet of more than 225 units transporting crude to various locations. 2. For the quarter ended March 31, 1999 and 1998, the Company was treated as a partnership for federal and most state income tax purposes, and the tax effect of its activities accrued to Marathon and Ashland. As a result, no provision for federal or state income taxes has been made in the accompanying financial statements. 3. For purposes of these separate financial statements, payables and receivables related to transactions between the Company and MAP are included as a component of the Parent Company investment. Transactions during the first quarter of 1999 between the Scurlock Permian Businesses and Marathon and Ashland are considered to be related party transactions. 4. At December 31, 1998, the Company recorded a charge to earnings of approximately $10 million to reflect an inventory market valuation reserve. Such amount represented the amount by which the recorded LIFO cost basis of crude oil inventory exceeded net realizable value as of such date. At March 31, 1999, the inventory market valuation reserve was released due to increased crude oil prices and the Company recognized a credit to earnings of approximately $10 million. 5. The Company is the subject of, or party to, a number of pending or threatened legal actions, contingencies and commitments involving a variety of matters, including laws and regulations relating to the environment. Under the agreement for the sale of the Company by MAP to Plains, MAP has agreed to indemnify and hold harmless the Company and Plains for claims, liabilities and losses (collectively "Losses") resulting from any act or omission attributable to the Company's business or properties occurring prior to the date of the closing of such sale to the extent the aggregate amount of such Losses exceed $1 million; provided however, that claims for such Losses must be asserted by the Company against MAP on or before May 15, 2003. Certain identified Losses and the first $25,000 of any individual claim are not included in the calculation of the foregoing $1 million indemnification threshold. F-4

NOTES TO FINANCIAL STATEMENTS SCURLOCK PERMIAN BUSINESSES NOTE A - BUSINESS DESCRIPTION AND BASIS OF PRESENTATION Scurlock Permian LLC (SPLLC) is a wholly owned subsidiary of Marathon Ashland Petroleum LLC (MAP). MAP was formed effective January 1, 1998, and is owned 62% by Marathon Oil Company (Marathon) and 38% by Ashland Inc. (Ashland). Prior to January 1, 1998, SPLLC was organized as a stock corporation named Scurlock Permian Corporation and was a wholly owned subsidiary of Ashland. Throughout these financial statements, the term, Parent Company, relates to MAP for 1998 and Ashland for 1997 and 1996. On March 17, 1999, MAP entered into an agreement with Plains Marketing, L.P. (Plains) providing for the sale of MAP's membership interest in SPLLC and certain other pipeline assets (collectively, the Scurlock Permian Businesses or the Company) to Plains. This transaction is anticipated to be consummated in the second quarter of 1999. The accompanying financial statements do not include any adjustments that might result from the proposed sale. The accompanying financial statements pertain to the business that is being sold to Plains and represent a carve-out financial statement presentation of a MAP operating unit as of and for the year ended December 31, 1998, and of Scurlock Permian Corporation (the Predecessor) as of December 31, 1997 and 1996 and for the years then ended. The financial statements include allocations and estimates of direct and indirect Parent Company corporate administrative costs attributable to the Company or the Predecessor as described in Note D. The methods by which such amounts are attributed or allocated are deemed reasonable by the Parent Company's management. The financial information herein is not necessarily indicative of the financial position, results of operations and cash flows that would have been reported if the Company or the Predecessor had operated as an unaffiliated enterprise, nor is it indicative of future results. In connection with the formation of MAP, Marathon acquired certain refining, marketing and transportation net assets, including the operations comprising SPLLC, from Ashland in exchange for a 38% interest in MAP. The acquisition of Ashland's net assets was accounted for under the purchase method of accounting. As a result, the financial statements of the Scurlock Permian Businesses for the year ended December 31, 1998, were prepared on a different basis than the financial statements of the Predecessor for the years ended December 31, 1997 and 1996. Due to this lack of comparability, a "black line" has been used to separate the reporting periods. The Company and the Predecessor are independent gatherers and marketers of crude oil in the United States, operating in 14 states. Major operations consist of pipeline, barge and truck operations. The pipeline component owns and operates more than 2,400 miles of active pipelines that transport crude oil from leases and unloading stations to major pipeline connections and terminals. The barge facilities consist of eight owned barge terminals located in Louisiana and Texas. The truck operations consist of a fleet of more than 250 units transporting crude to various locations. NOTE B - SUMMARY OF PRINCIPAL ACCOUNTING POLICIES PRINCIPLES APPLIED IN CONSOLIDATION - The investment in the entity over which the Company or the Predecessor has significant influence is accounted for using the equity method. The proportionate share of income from this equity method investment is included in revenues. The investment in the other entity over which the Company or the Predecessor does not have significant influence and whose stock does not have a readily determinable fair value is carried at cost. USE OF ESTIMATES - Generally accepted accounting principles require management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at year end and the reported amounts of revenues and expenses during the year. Significant items subject to such estimates and assumptions include the carrying value of long- lived assets, valuation allowances for receivables and inventories, environmental liabilities and liabilities for potential claims and settlements. Actual results could differ from the estimates and assumptions used. REVENUE RECOGNITION - Revenues principally include sales, equity income and gains or losses on the disposal of assets. Sales are recognized when products are shipped or services are provided to customers. Matching crude oil buy/sell transactions settled in cash are included in both revenues and costs and expenses, with no effect on income. As of December 31, 1998 and 1997, receivables from two customers comprised 11 percent and 12 percent, respectively, of total receivables. F-11

NOTES TO FINANCIAL STATEMENTS - Continued NOTE B - SUMMARY OF PRINCIPAL ACCOUNTING POLICIES - Continued CASH AND CASH EQUIVALENTS - Cash and cash equivalents include cash on hand and on deposit. The Company and the Predecessor participate in the Parent Company's centralized funding and cash management system (non-interest bearing) (see Note D). INVENTORIES - Inventories are carried at lower of cost or market. Cost of inventories is determined primarily under the last-in, first-out (LIFO) method. DERIVATIVE INSTRUMENTS - The Company and the Predecessor engage in commodity risk management activities within the normal course of its business as an end- user of derivative instruments (see Note M). Management is authorized to manage exposure to price fluctuations related to the purchase and sale of crude oil through the use of derivative non-financial instruments. Derivative non- financial instruments require or permit settlement by delivery of commodities and include exchange-traded commodity futures contracts. The Company's and the Predecessor's practices do not permit derivative positions to remain open if the underlying physical market risk has been removed. Changes in the market value of derivative instruments are deferred, including both closed and open positions, and are subsequently recognized in income, as sales or cost of sales, in the same period as the underlying transaction. The margin receivable accounts required for open commodity contracts reflect changes in the market prices of the underlying commodity and are settled on a daily basis. Recorded deferred gains or losses are reflected within other current assets or accounts payable. Cash flows from the use of derivative instruments are reported in the same category as the hedged item in the Statement of Cash Flows. LONG-LIVED ASSETS - Property, plant and equipment are stated at cost and are depreciated principally by the straight-line method based on estimated useful lives of: a) 15 years for right of way, b) 5 to 15 years for building and furniture, and c) 3 to 15 years for transportation and terminal equipment. Impairment of assets is evaluated on an individual asset basis or by logical groupings of assets. Assets deemed to be impaired are written down to their fair value, including any related goodwill, using discounted future cash flows and, if available, comparable market values. ENVIRONMENTAL LIABILITIES - Provision is made for remediation costs and penalties when the responsibility to remediate is probable and the amount of associated costs is reasonably determinable. Generally, the timing of remediation accruals coincides with completion of a feasibility study or the commitment to a formal plan of action. Remediation liabilities are accrued based on estimates of known environmental exposure (see Note N). INSURANCE - The Company and the Predecessor maintain insurance for catastrophic casualty and certain property and business interruption exposures, as well as those risks required to be insured by law or contract. Costs resulting from noninsured losses are charged against income upon occurrence. INCOME TAXES - For the year ended December 31, 1998, the Company was treated as a partnership for federal and most state income tax purposes, and the tax effect of its activities accrued to Marathon and Ashland. As a result, no provision for federal or state income taxes has been made in the accompanying financial statements for 1998 activity. Prior to January 1, 1998, when the Predecessor was wholly owned by Ashland, it operated as a corporation. Accordingly, these financial statements include a provision for income taxes for the periods ended December 31, 1997 and 1996. Income taxes pertaining to the years 1997 and 1996 are computed on a separate return basis using the liability method as prescribed by Statement of Financial Accounting Standards No. 109, "Accounting for Income Taxes." Because the Predecessor was included in the federal and state income tax returns filed by Ashland, the calculation of the related tax provisions and deferred taxes necessarily requires certain assumptions, allocations and estimates which management believes are reasonable to reflect the tax reporting for the Predecessor as a stand-alone taxpayer. FAIR VALUE OF FINANCIAL INSTRUMENTS - The carrying values of most financial instruments are based on historical costs. The carrying values of cash and cash equivalents, receivables and payables approximate their fair value due to the short-term maturity of these instruments. F-12

NOTES TO FINANCIAL STATEMENTS - Continued NOTE C - NEW ACCOUNTING STANDARD In June 1998, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 133, "Accounting for Derivative Instruments and Hedging Activities" (SFAS No. 133). This new standard requires recognition of all derivatives as either assets or liabilities at fair value. SFAS No. 133 may result in additional volatility in both current period earnings and other comprehensive income as a result of recording recognized and unrecognized gains and losses resulting from changes in the fair value of derivative instruments. SFAS 133 requires a comprehensive review of all outstanding derivative instruments to determine whether or not their use meets the hedge accounting criteria. It is possible that there will be derivative instruments employed in the Company's businesses that do not meet all of the designated hedge criteria, and they will be reflected in income on a mark-to-market basis. Based upon the strategies currently employed by the Company, the relatively short-term duration of most of the Company's derivative strategies, and the level of activity related to commodity-based derivative instruments in recent periods, the Company does not anticipate the effect of adoption to have a material impact on either financial position or results of operations. The Company plans to adopt SFAS No. 133 effective January 1, 2000, as required. NOTE D - PARENT COMPANY INVESTMENT, ALLOCATIONS AND RELATED PARTY TRANSACTIONS For purposes of these separate financial statements, payables and receivables related to transactions between the Company and MAP and the Predecessor and Ashland, as well as payables and refunds related to income taxes, are included as a component of the Parent Company investment. Transactions in 1998 between the Scurlock Permian Businesses and Marathon and Ashland are considered to be related party transactions. The Company's sales in 1998 to Ashland were $580 thousand; sales to MAP were $732,832 thousand; and sales to Marathon were $2,195 thousand. The Predecessor's sales in 1997 and 1996 to Ashland were $793,920 thousand and $942,299 thousand, respectively. The Company's purchases in 1998 from MAP totaled $106,317 thousand and purchases from Marathon were $9,531 thousand. The Predecessor's purchases in 1997 and 1996 from Ashland totaled $129,816 thousand and $121,837 thousand, respectively. Such transactions were in the ordinary course of business and include the purchase, sale and transportation of crude oil. MAP, Ashland and Marathon provided computer, treasury, accounting, internal auditing and legal services to the Company in 1998 and Ashland provided such services to the Predecessor in 1997 and 1996. Charges for these services were allocated based on usage or other methods, such as headcount and square footage, that management believed to be reasonable. Charges to the Company for these services for the year ended December 31, 1998 totaled $7,722 thousand. Ashland charges for these services in 1997 and 1996 were $7,787 thousand and $6,423 thousand, respectively. The Parent Company uses a centralized cash management system (non-interest bearing) under which cash receipts of the Company and the Predecessor were remitted to the Parent Company and cash disbursements of the Company and the Predecessor were funded by the Parent Company. As of December 31, 1998, receivables included $832 thousand due from Ashland. The Company's accounts payable as of December 31, 1998, included $1,601 thousand due to Marathon. NOTE E - REVENUES The items below are included in revenues and costs and expenses, with no effect on income. <TABLE> <CAPTION> (Predecessor) (Company) Year Ended Year Ended ------------------------------------- December 31, 1998 December 31, 1997 December 31, 1996 ----------------- ----------------- ----------------- (Thousands) (Thousands) <S> <C> <C> <C> Matching crude oil buy/sell transactions settled in cash $2,179,843 $2,851,069 $2,665,054 </TABLE> F-13

NOTES TO FINANCIAL STATEMENTS - Continued NOTE F - EMPLOYEE BENEFITS For the purposes of these financial statements, the Company and the Predecessor are considered to participate in multi-employer benefit plans. The Company's employees were included in the various employee benefit plans of MAP in 1998 and the Predecessor's employees were included in the various employee benefit plans of Ashland for the years ended December 31, 1997 and 1996. These plans included retirement plans, employee and retiree medical, dental and life insurance plans, 401(k) and profit-sharing plans and other such benefits. MAP has noncontributory defined benefit pension plans covering substantially all employees of the Scurlock Permian Businesses. Benefits under these plans are based primarily upon years of service and career earnings. The funding policy for all plans provides that payments to the pension trusts shall be equal to the minimum funding requirements of the Employee Retirement and Income Security Act, plus such additional amounts as may be approved. No charges have been allocated to the Scurlock Permian Businesses for the MAP defined benefit pension plans for the year ended December 31, 1998, as the plans are in an overfunded position. MAP also has defined benefit retiree health insurance plans covering most employees of the Scurlock Permian Businesses upon their retirement. Health benefits are primarily provided through comprehensive hospital, surgical and major medical benefit provisions subject to various cost-sharing features. The Company's and the Predecessor's share of employee benefit expenses were $3,121 thousand, $4,815 thousand and $4,117 thousand for the years ended December 31, 1998, 1997 and 1996, respectively. NOTE G - INCOME TAXES Provision (benefit) for estimated income taxes: <TABLE> <CAPTION> (Predecessor) Year Ended -------------------------------------- December 31, 1997 December 31, 1996 ----------------- ----------------- (Thousands) (Thousands) <S> <C> <C> FEDERAL TAXES: Current $ 821 $1,389 Deferred (2,057) 1,657 ------- ------ Total federal taxes (1,236) 3,046 STATE AND LOCAL TAXES: 60 102 ------- ------ Total provision (benefit) $(1,176) $3,148 ======= ====== </TABLE> For the year ended December 31, 1998, the Company was treated as a partnership for federal and most state income tax purposes and the tax effect of its activities accrued to Marathon and Ashland. As a result, no provision for income taxes has been made in the accompanying financial statements for 1998 activity. Prior to January 1, 1998, the Predecessor was wholly owned by Ashland and operated as a corporation. Accordingly, these financial statements include a provision for income taxes for the periods ended December 31, 1997 and 1996. Income taxes pertaining to the years 1997 and 1996 are computed on a separate return basis using the liability method as prescribed by Statement of Financial Accounting Standards No. 109. The deferred tax asset and liability at December 31, 1997 principally arise from differences between the book and tax basis of inventory and property, plant and equipment, respectively. F-14

NOTES TO FINANCIAL STATEMENTS - Continued NOTE G - INCOME TAXES - Continued A reconciliation of the federal statutory tax rate (35%) to the total income tax provision (benefit) follows: (Predecessor) 1997 1996 ----------- ----------- (Thousands) (Thousands) Statutory rate applied to income before income taxes $(1,590) $2,684 Nondeductible goodwill and business expenses 375 398 State and local income taxes after federal income tax benefit 39 66 ------- ------ Total provision (benefit) $(1,176) $3,148 ======= ====== NOTE H - INVENTORIES Inventories consist of the following: (Company) (Predecessor) December 31, 1998 December 31, 1997 ----------------- ----------------- (Thousands) (Thousands) Crude oil $21,294 $24,417 Pipeline line fill 4,638 6,273 Materials and supplies 2,004 2,248 Bulk fuel 336 408 ------- ------- Total (at cost) 28,272 33,346 Less inventory market valuation reserve 10,014 6,485 ------- ------- Net inventory carrying value $18,258 $26,861 ======= ======= Inventories of crude oil and pipeline line fill are valued by the LIFO method. At December 31, 1998 and 1997, the LIFO method accounted for approximately 92% of the total inventory value. During 1997, inventory quantities were reduced. This reduction resulted in a liquidation of LIFO inventory quantities carried at lower costs prevailing in prior years as compared with the cost of 1997 purchases, the effect of which decreased cost of goods sold by approximately $1,382 thousand and increased net income by approximately $898 thousand. The inventory market valuation reserve reflects the extent that the recorded LIFO cost basis of crude oil inventories exceeds net realizable value. The reserve is decreased to reflect increases in market prices and inventory turnover and increased to reflect decreases in market prices. Changes in the inventory market valuation reserve result in noncash charges or credits to costs and expenses. F-15

F-17

NOTES TO FINANCIAL STATEMENTS - Continued NOTE M - DERIVATIVE INSTRUMENTS The Company and the Predecessor use exchange-traded future contracts to manage exposure to price fluctuations related to the anticipated purchase and sale of crude oil. The exchange-traded futures contracts do not have a corresponding fair value since changes in market prices are settled on a daily basis. The Company remains at risk for possible changes in the market value of the derivative instrument; however, such risk should be mitigated by price changes in the underlying hedged item. The following table sets forth quantitative information for exchange-traded commodity futures: Recorded Deferred Aggregate Gain or Contract (Loss) Values (a) ------------ ---------------- (Thousands) (Thousands) (Company) DECEMBER 31, 1998: Exchange-traded commodity futures $ 191 $ 8,964 (Predecessor) DECEMBER 31, 1997: Exchange-traded commodity futures $(2,817) $29,157 (a) Contract or notional amounts do not quantify risk exposure, but are used in the calculation of cash settlements under the contracts. The contract or notional amounts do not reflect the extent to which positions may offset one another. NOTE N - CONTINGENCIES AND COMMITMENTS The Company and the Predecessor are the subject of, or party to, a number of pending or threatened legal actions, contingencies and commitments involving a variety of matters, including laws and regulations relating to the environment. Certain of these matters are discussed below. The ultimate resolution of these contingencies could, individually or in the aggregate, be material to the Company's financial statements. However, the Company's management believes that the Company will remain a viable and competitive enterprise even though it is possible that these contingencies could be resolved unfavorably. ENVIRONMENTAL MATTERS - The Company and the Predecessor are subject to federal, state, and local laws and regulations relating to the environment. These laws generally provide for control of pollutants released into the environment and require responsible parties to undertake remediation of hazardous waste disposal sites. Penalties may be imposed for noncompliance. At December 31, 1997, the Predecessor had $4,228 thousand accrued for remediation costs on existing properties. In connection with the formation of MAP (see Note A), Marathon and Ashland retained the liability, subject to certain thresholds, for costs associated with remediating conditions existing prior to January 1, 1998. No amounts were accrued by the Company at December 31, 1998 for environmental matters. It is not presently possible to estimate the ultimate amount of all remediation costs that might be incurred or the penalties that may be imposed. COMMITMENTS - The Company has a contract for use of an oil terminal in Louisiana with an initial three-year term that began on July 1, 1998. At the end of three years, the agreement will automatically extend from year to year unless either party cancels it. The Company is committed to a "minimum receipt throughput volume" of 4,500 barrels per day at $.25 per barrel. F-18

PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS OF PLAINS ALL AMERICAN PIPELINE, L.P. AND SUBSIDIARIES INTRODUCTION The accompanying unaudited pro forma consolidated financial statements are presented to reflect the acquisition of Scurlock Permian LLC and certain other pipeline assets (the "Scurlock Acquisition") from Marathon Ashland Petroleum LLC ("MAP") by Plains Scurlock Permian, L.P. ("Plains Scurlock"), a newly formed operating limited partnership of Plains All American Pipeline, L.P. ("PAA"). The Scurlock Acquisition has been accounted for using the purchase method of accounting. The pro forma consolidated balance sheet as of March 31, 1999 and the pro forma consolidated statement of income for the three months ended March 31, 1999 are based upon the historical financial statements of PAA, and the Scurlock Permian Businesses ("Scurlock"). The Scurlock financial statements pertain to the business sold to PAA by MAP and represent a carve-out financial statement presentation of a MAP operating unit. PAA is a limited partnership formed in the third quarter of 1998, to acquire and operate the midstream crude oil business and assets of Plains Resources Inc. and its wholly owned subsidiaries (the "Plains Midstream Subsidiaries" or the "Predecessor"). On November 23, 1998, PAA completed the initial public offering and the transactions whereby PAA became the successor to the business of the Predecessor. The pro forma consolidated statement of operations for the year ended December 31, 1998, is based on the historical consolidated income statement of PAA (for the period from November 23, 1998 to December 31, 1998), the historical combined income statement of the Predecessor (for the period from January 1, 1998 to November 22, 1998), and the historical statement of operations of Scurlock for the year ended December 31, 1998. The unaudited pro forma consolidated financial statements are not necessarily indicative of the results of the future operations of PAA. The unaudited pro forma consolidated financial statements should be read in conjunction with the notes thereto and the historical financial statements of Scurlock, included in Item 7 (a) of this Form 8-K. In addition, reference should be made to the historical financial statements of PAA included in Form 10-K for the year ended December 31, 1998, and included in Form 10-Q for the three months ended March 31, 1999, filed with the Securities and Exchange Commission. The following unaudited pro forma consolidated financial statements have been prepared as if the Scurlock Acquisition and related transactions had taken place on March 31, 1999, in the case of the pro forma consolidated balance sheet or as of January 1, 1998 in the case of the pro forma consolidated statement of income for the three months ended March 31, 1999, and the pro forma consolidated statement of operations for year ended December 31, 1998.

PLAINS ALL AMERICAN PIPELINE, L.P. AND SUBSIDIARIES NOTES TO PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) Pro Forma Adjustments A. Reflects the financing for the Scurlock Acquisition which was provided through (i) a limited recourse bank facility with BankBoston, N.A. (the "Plains Scurlock Credit Facility"), (ii) the sale to PAA's general partner ("General Partner") of 1.3 million Class B Common Units of PAA ("Class B Units") at $19.125 per unit, the price equal to the market value of PAA's common units and (iii) a $25 million draw under PAA's existing revolving credit agreement. In addition, the General Partner's $0.3 million capital contribution resulting from the sale of the Class B Units is reflected. The Class B Units are initially pari passu with Common Units with respect to distributions, and after six months are convertible into Common Units upon approval of a majority of Common Unitholders. After such six month period, the Class B Unitholder may request that PAA call a meeting of Common Unitholders to consider approval of the conversion of Class B Units into Common Units. If the approval of such conversion by the Common Unitholders is not obtained within 120 days of such request (the "Initial Approval Period"), the Class B Unitholders will be entitled to receive distributions, on a per unit basis, equal to 110% of the amount of distributions paid on a Common Unit, with such distribution right increasing to 115% if such approval is not secured within 90 days after the end of the Initial Approval Period. Except for the vote to approve the conversion, Class B Units have the same voting rights as the Common Units. B. Reflects the consummation of the Scurlock Acquisition and the related purchase accounting entries. The purchase price was allocated in accordance with APB 16 as follows (in thousands): Crude oil pipeline, gathering and termial assets $129,215 Pipeline linefill 16,057 Debt issue costs 2,688 Net working capital items (2,089) -------- Cash paid $145,871 ======== The purchase price allocation has been based on preliminary estimates of fair value and is subject to adjustment as additional information becomes available and is evaluated. Minimum amounts of crude oil which are required to operate Scurlock's pipeline and gathering assets have been classified as pipeline linefill, a long-term asset. Such amounts were classified as a current asset and included in inventory by Scurlock. C. Reflects the reclassification of Scurlock receivables from and payables to MAP for crude oil purchases. Such amounts, which were repaid by MAP subsequent to March 31, 1999, are reflected in the Scurlock financial statements as a component of Parent Company Investment. D. Reflects the elimination of revenues and expenses associated with certain assets and liabilities that were retained by MAP at the date of the Scurlock Acquisition which were included in Scurlock's historical financial statements as of and for the year ended December 31, 1998. Such assets and liabilities and related revenues and expenses are not included in Scurlock's historical financial statements as of and for the three months ended March 31, 1999. E. Reflects pro forma interest expense on (i) borrowings of approximately $95.6 million under the Plains Scurlock Credit Facility and (ii) borrowings of $25 million under PAA's existing credit facility. PAA has entered into a series of 5-year interest rate collars, which provide for a floor of 5.04% and a ceiling of 6.5% on a notional principal amount of $90 million of the LIBOR portion outstanding under the Plains Scurlock Credit Facility. F. Reflects pro forma depreciation and amortization expense based on the purchase price of the Scurlock assets by PAA. G. Reflects the elimination of historical Scurlock depreciation and amortization expense. H. Reflects the reduction in compensation and benefits expense due to staff reductions implemented by PAA. Such amounts are based on historical expenses incurred by Scurlock. The reductions took place at the date of the Scurlock Acquisition and PAA has no plans to replace these personnel. The reduction in personnel is not expected to adversely impact PAA's revenues or costs. This adjustment does not include an additional $3.2 million of estimated reductions in compensation and benefits expense related to staff reductions implemented by Scurlock in the fourth quarter of December 1998. F-23

I.

Reflects the elimination of expenses associated with MAP's profit sharing and post retirement pension, health and benefit plans in which Scurlock's employees are no longer entitled to participate so that cost of sales and operations and general and administrative expense reflect the ongoing cost of employee benefits to PAA. N. Reflects the elimination of expenses related to the sale of Scurlock by MAP. Such amounts are primarily related to employee retention and bonuses paid in connection with the sale of Scurlock. O.
