ACQUISITION OR DISPOSITION OF ASSETS On November 16, 1999, Frontier El Dorado Refining Company ("FEDRC"), an indirect wholly-owned subsidiary of Frontier Oil Corporation (the "Company"), acquired the 110,000 barrel per day ("bpd") crude oil refinery located in El Dorado, Kansas from Equilon Enterprises LLC ("Equilon"). The acquired assets were used by Equilon to refine crude oil. The Company intends to continue such use. The Company also purchased the crude oil, intermediate product and finished product inventories at the refinery at closing. Total consideration for the acquisition of the refinery consisted of $170 million cash. In addition, the Company will make contingent earn-out payments for the next eight years equal to one-half of the excess over $60 million per year of the El Dorado refinery's revenues less its material costs and operating costs, other than depreciation. The total amount of these contingent payments is capped at $40 million, with an annual cap of $7.5 million. Total consideration for the acquisition of the inventory at closing consisted of approximately $50.8 million cash. The acquisition will be accounted for under the purchase method of accounting for financial reporting purposes. The sources of financing for the cash portion of the acquisition consideration were (i) approximately $180 million of net proceeds from the issuance of the $190 million aggregate principal amount of the Company's 11-3/4% Senior Notes due 2009 on November 5, 1999 and (ii) approximately $40 million under a new credit facility established by Frontier Oil and Refining Company ("FORC"), an indirect wholly-owned subsidiary of the Company, with Union Bank of California, N.A., as administrative agent, documentation agent and lead arranger, and Paribas, as syndication agent and lead arranger. The El Dorado refinery, which produces gasoline, diesel and jet fuel, and asphalt and other products, serves the Denver market via pipeline and additionally serves Kansas City and other important markets in the Kansas, Nebraska, Iowa, Missouri, North Dakota and South Dakota. Assets of the El Dorado refinery also include a small petrochemical plant and a leased 38 megawatt cogeneration facility. The Refinery is a complex refinery and includes the following major processing units: crude/vacuum unit, hydrotreating units, reformer complex, coker, fluid catalytic cracking unit, alkylation unit, and an avgas/naphtha fractionation unit. The purchase price and all negotiations relating to the El Dorado Refinery acquisition were on an arm's length basis. - 1 - ITEM 7.

Basis of Presentation In October 1999, Frontier Oil Corporation (the "Company") signed an agreement to acquire from Equilon Enterprises LLC ("Equilon"), a refinery located in El Dorado, Kansas, for approximately $170 million. In addition, the Company will purchase the hydrocarbon inventory located at the refinery on the closing date. The acquisition is expected to close in November 1999. The Statements of Income Before Interest and Income Taxes associated with the El Dorado refinery were derived from Equilon's accounting records. Certain expense items not directly associated with the El Dorado refinery, such as interest, income taxes and corporate overhead, were not recorded in the El Dorado refinery's accounting records. Any allocation of such costs would be arbitrary and would not be indicative of what such costs actually would have been had the El Dorado refinery been operated as a stand-alone entity. Because of the lack of segregated or easily obtainable and reliable data for asset and liability balances other than property, plant and equipment and inventories, a balance sheet is not presented for the El Dorado refinery. 2. Related Party Transactions Sales of refined products from the El Dorado refinery were primarily intercompany in nature based on prevailing refined product market prices. Such intercompany sales amounted to $940,979,000, $877,135,000 and $643,564,000 for the years ended December 31, 1996, 1997 and 1998, respectively. Intercompany sales amounted to $495,820,000 (unaudited) and 573,972,000 (unaudited) for the nine months ended September 30, 1998 and 1999, respectively. Substantially all crude purchases were intercompany in nature based on prevailing crude market prices. 3. Acquired Assets The following tables present the historical cost of the fixed assets and inventories of the El Dorado refinery, as of December 31, 1997 and 1998 and September 30, 1999 (in thousands).

In the second quarter of 1999, Equilon recorded an impairment charge of approximately $190.6 million (unaudited), in accordance with Statement of Financial Accounting Standards (SFAS) No. 121 "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of," to reduce the carrying value of the El Dorado refinery to the estimated sales price of $170 million. - 6 - December 31, December 31, September 30, 1997 1998 1999 ------------ ------------ ------------- (unaudited) Hydrocarbon Inventories $ 19,930 $ 26,767 $ 15,098 Materials and Supplies 11,400 7,700 8,087 ------------ ------------ ------------- Total Inventories $ 31,330 $ 34,467 $ 23,185 ============ ============ ============= All inventories are valued at the lower of cost or market. The cost of hydrocarbon inventories is determined on the last-in, first-out (LIFO) method, while materials and supplies are stated at average cost. The excess of market value over the book value of inventories carried at cost on the LIFO basis of accounting was approximately $33.9 million, $8.8 million and $32.6 million (unaudited) at December 31, 1997 and 1998 and September 30, 1999, respectively. 4. Subsequent Event (subsequent to the date of auditor's examination and unaudited) On November 16, 1999, the Company completed the purchase of the El Dorado refinery for a price of $170 million. - 7 - ITEM 7(b) UNAUDITED PRO FORMA FINANCIAL INFORMATION The following unaudited pro forma condensed consolidated financial information of Frontier is based on the historical financial statements of Frontier, adjusted to give effect to the acquisition of the El Dorado refinery and its inventory (the "Acquisition") and the related issuance of senior debt obligations and borrowings under Frontier's credit facility (together, the "Debt Issuances"). The pro forma balance sheet as of September 30, 1999 assumes the Acquisition and Debt Issuances occurred as of September 30, 1999. The pro forma statements of operations for the year ended December 31, 1998 and the nine months ended September 30, 1999 assume the Acquisition and Debt Issuances had occurred on January 1, 1998. The pro forma condensed consolidated financial information is not necessarily indicative of the results that actually would have occurred if the acquisition had been in effect on the dates indicated or which may be obtained in the future. The pro forma condensed financial information should be read in conjunction with the separate historical financial statements of Frontier, incorporated by reference in this document, and the El Dorado refinery included herein. -

11 - NOTES TO UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS (a) To reflect the adjustment to cash as a result of the issuance of the notes and borrowings under the new credit facility, as follows (in thousands): Proceeds from issuance of the notes, net of issuance costs $ 180,768 Proceeds from borrowings under the new credit facility, net of credit facility fees 45,093 --------- Total net proceeds $ 225,861 ========= (b) To reflect the acquisition of the El Dorado refinery. The El Dorado refinery acquisition will be accounted for as a purchase and the acquired assets and liabilities are included in the September 30, 1999 pro forma balance sheet of Frontier at values based on a preliminary allocation of the purchase price. The purchase price allocation is expected to be finalized during 2000 based upon further evaluation of the acquired assets. The preliminary purchase price allocation is as follows (in thousands): September 30, 1999 ------------- Inventory-crude oil, intermediate product and refined product $ 47,718 Inventory-parts and supplies, chemicals 8,087 Property, plant and equipment 204,340 Accrued liabilities (3,000) Accrued turnaround costs (22,331) Post-retirement employee liabilities (17,096) ------------- $ 217,718 ============= (c) The adjustment to other assets consists of $6.5 million of cost related to the issuance of the notes and $2.6 million of costs related to the arrangement of the new credit facility. (d) To reflect borrowings under the bank credit facility to purchase the El Dorado refinery inventory at closing. (e) To reflect the issuance of $190,000,000 of 11-3/4% Senior Notes. (f) To adjust refining operating expenses to reflect inventories on a FIFO basis of accounting used by Frontier. (g) To record (1) the reversal of historical El Dorado refinery depreciation and (2) pro forma depreciation based on preliminary purchase price allocation to the El Dorado refinery property, plant and equipment. (h) To reverse the El Dorado refinery second quarter 1999 impairment expense. In the second quarter of 1999, Equilon recorded an impairment charge of approximately $190.6 million, in accordance with Statement of Financial Accounting Standards (SFAS) No. 121 "Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed Of," to reduce the carrying value of the El Dorado refinery to the estimated sales price of $170 million. - 12 - (i) Reflects the adjustment to interest expense relating to the offering of the notes and borrowings under the bank credit facility, as follows (in thousands): Nine Months Year Ended Ended December 31, September 30, 1998 1998 ------------ ------------- Interest expense on notes and new credit facility* $ 26,321 $ 19,741 Amortization of debt issue costs and discount 1,675 1,257 ------------ ------------- Adjustment to interest expense $ 27,996 $ 20,998 ============ ============= _________ * Interest expense on the new credit facility is calculated as if the $47.8 million borrowed to acquire the crude oil, intermediate product and refined product inventory in the acquisition remains outstanding for the periods presented. Frontier believes interest expense for the new credit facility will be lower as average borrowings under the facility are expected to be less than $47.8 million. A $10 million average decrease in borrowings under the facility will decrease interest expense by $838,000 per year. (j) To reflect the income tax expense effects of pro forma adjustments at an assumed state tax rate of 5%. No U.S. federal income tax expense is reflected in the accompanying pro forma statements of operations as Frontier has $125.2 million of regular net operating loss carryforwards at December 31, 1998 to reduce future federal taxable income. - 13 - SIGNATURES Pursuant to the requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned, thereunto duly authorized.
