Management's Discussion and Analysis General In 1997 the Company decided to focus entirely on its refining business and to divest its remaining exploration and production operations. The Company had previously completed the sale of its domestic oil and gas properties (the "U.S. Disposition") in 1995, and in June 1997, it closed the sale of all of its Canadian oil and gas properties (the "Canadian Disposition"). After such dispositions, the Company's primary continuing operation is the Frontier Refinery. Accordingly, the Company's operating results for its oil and gas operations segment, comprising the oil and gas properties divested in the U.S. Disposition and the Canadian Disposition, are presented as discontinued operations in the consolidated financial statements. The Company experiences stronger demand for its refined products, particularly gasoline and asphalt, during the summer months due to seasonal increases in highway traffic and road construction work. As a result, the Company's operating results for the first and fourth calendar quarters are generally lower than those for the second and third quarters. Demand for diesel is more stable, but reduced road construction and agricultural work during the winter months does have an impact on demand for diesel. Consistent with the seasonality of its business, the Company invests in working capital during the first half of the year and recovers working capital investment in the second half of the year. Results of Operations 1997 Compared with 1996. The Company had net income for the year ended December 31, 1997 of $19.1 million or $0.69 per share, compared to a loss of $6.9 million or ($0.25) per share for 1996. The 1997 results include a $23.3 million gain resulting from the Canadian Disposition which closed on June 16, 1997, a $9.9 million reduction to income in recognition of the cumulative translation adjustment and a $3.9 million extraordinary loss on early retirement of debt. Operating income increased by $16.1 million in the year ended December 31, 1997 as compared to 1996 due to an increase in the refined product spread (revenues less material costs) of $19.5 million and an increase in other income of $1.1 million, offset by an increase in refining operating expenses of $2.6 million and selling and general costs of $1.8 million. Refined product revenues and refining operating costs are impacted by changes in the price of crude oil. The price of crude oil was lower in 1997 than in 1996. The refined product spread for 1997 was $5.78 per bbl compared to $4.48 per bbl for 1996. The refined product spread increased due to better light product margins, primarily gasoline, and an improved light/heavy spread which more than offset inventory losses in the first quarter of 1997 of approximately $4.0 million from a decline in crude oil prices of more than $6.00 per bbl. Inventories are recorded at the lower of cost on a FIFO basis or market. Refined product revenues decreased $8.0 million, or 2%, in 1997 as compared to 1996. The decrease in refined product revenues resulted primarily from $1.67 per bbl decrease in average diesel sales prices offset by a $0.05 per bbl increase in average gasoline sales prices. Refined product sales volumes were nearly the same for the 1997 and 1996 periods. Other income increased $1.1 million to $2.3 million for the year ended December 31, 1997 as compared to 1996 mostly due to foreign currency transaction gains of $522,000 related to the Canadian sales proceeds and higher processing fees. Refining operating costs decreased $25.0 million, or 7%, in the year ended December 31, 1997 from 1996 due to a $27.6 million decrease in material costs partially offset by an increase in refining operating expenses of $2.6 million. Material costs per bbl decreased 9%, or $2.01 per bbl in 1997 due to lower oil prices, lower crude oil charges, increased use of heavy crude oil and an increase in the light/heavy spread. The crude oil charge rate declined by 870 bpd in 1997 due to turnaround work conducted on the crude unit in the fourth quarter of 1997. During 1997, Frontier increased its use of heavy crude oil by 1% and the heavy crude oil utilization rate expressed as a percent of total crude oil increased to 91% in 1997 from 88% in 1996. In addition, the light/heavy - 10 - spread increased 38% to average $3.54 per bbl for the year ended December 31, 1997 because the Company contracted for approximately 30,000 bpd of Wyoming and Canadian heavy crude oil for much of 1997 at a light/heavy spread substantially better than it obtained for the same period in 1996. For 1998, the Company has contracted for an average of 29,000 bpd of Wyoming and Canadian heavy crudes at a light/heavy spread ranging from $4.80 to $5.25 per bbl. Refining operating expenses increased by $0.15 per bbl to $3.30 due to higher maintenance and turnaround costs and leased equipment costs offset by decreased natural gas and utility costs. Prior year operating expenses were reduced by a $1.3 million settlement of repair costs rela ted to a 1995 pipeline gas explosion. Although efforts to reduce refining operating expenses will continue, maintenance problems may arise in the future, resulting in downtime of certain processing units and reduced yields which may increase operating expenses and negatively impact profitability. A major turnaround is scheduled in the spring of 1998 on the fluid catalytic cracking unit and alkylation and related units. These units are scheduled to be down for 28 days, which will decrease average yields during that time. Other turnaround work is scheduled for several Refinery units during 1998, but this work should not materially impact yields. Selling and general expenses increased $1.8 million, or 28%, for the year ended December 31, 1997 reflecting increases in salaries and benefits. Included in 1996 is $0.2 million of salary and salary-related expenses of certain employees who were not retained after March 31, 1996, in connection with the U.S. Disposition in late 1995 and a corporate reorganization in early 1996. Depreciation increased $152,000 or 2% for the year ended December 31, 1997 as compared to 1996. Such increase was attributable to ongoing capital investment in the Refinery. Net interest expense decreased by $3.3 million, or 19%, in the year ended December 31, 1997 as compared to 1996. Such decrease was attributable to interest income of $2.0 million earned primarily on the sale proceeds of the Canadian Disposition and reduced interest expense of $1.3 million due to early retirement of debt. On October 1, 1997, the Company retired $7.5 million of its 10-3/4% Subordinated Debentures, and by the end of 1997, $72.4 million principal amount of its 12% Senior Notes was retired. Average debt decreased from $154 million for the year ended December 31, 1996 to $138 million in 1997. Income from discontinued oil and gas operations includes the Company's Canadian oil and gas operation through May 5, 1997. Income from discontinued operations was $1.7 million for the year ended December 31, 1997 as compared to $4.8 million for 1996. 1996 Compared with 1995. Operating income increased $6.7 million, or 605%, in 1996 compared to 1995. Such increase was attributable to improved refined product spread of $5.9 million, reduced operating costs of $1.2 million and reduced selling and general costs of $0.9 million, offset by a decrease in other income of $0.8 million and an increased depreciation expense of $0.5 million. The 1995 other income was related to a settlement of a contract dispute. Refined products revenues and refining operating costs are impacted by changes in the price of crude oil. Generally, the price of crude oil remained strong throughout 1996 compared to a lower average price in 1995. The refined product spread increased 11%, to $4.48 per bbl, in 1996. Lower national distillate inventory levels in 1996 contributed to the improved diesel margins; however, a continued decline in the light/heavy spread in 1996 compared to 1995 increased material costs. The adverse impact of higher crude oil prices significantly reduced margins for by-products, such as asphalt, in 1996 compared to 1995 levels. In 1996, refined product revenues increased 16% from 1995 due to a $3.84 per bbl increase in average sales price, offset by a 2% decrease in sales volumes. - 11 - Refining operating costs increased $45.2 million, or 14%, in 1996 compared to 1995 due to a 17% increase in material costs associated with the strong worldwide crude oil market, offset by a reduction in the refining operating expenses of $1.2 million. During 1996, Frontier increased its use of heavy crude oil by 17% which favorably impacted material costs. The heavy crude oil utilization rate expressed as a percent of total crude oil increased to 88% in 1996 from 77% in 1995. The favorable impact of the increased use of heavy crude oil in 1996 was offset somewhat by the continued decline in the light/heavy spread during 1996. In 1996, the light/heavy spread declined 13% from 1995 to average $2.56 per bbl as a result of increased competition for Wyoming heavy crude oil and other sources of heavy crude oil in the Company's market area. However, in the fourth quarter of 1996, the Frontier Refinery experienced an increase in the light/heavy spread when it contracted for delivery in 1997 of approximately 25,000 bpd of Wyoming heavy crude oil at a light/heavy spread of $3.25 to $3.75 per bbl. The $1.2 million decrease in refinery operating expenses in 1996 was primarily attributable to recovery in the first quarter of 1996 of approximately $1.3 million of repair costs related to a pipeline gas explosion in 1995. The repair costs approximating $1.3 million in 1995, and related recovery in 1996, were both included in refinery operating expense. During 1996, refinery operating expenses were reduced in various categories including insurance and turnaround expense; however, these savings were offset by cost increases associated with higher natural gas prices and general maintenance costs. The strike by approximately 150 union employees which commenced May 8, 1996 and settled July 29, 1996 did not adversely impact operating costs or throughput. The increase in depreciation expense reflected in 1996 of $500,000, or 6%, from 1995 was primarily attributable to ongoing capital investment in the Frontier Refinery. Selling and general expenses decreased $0.9 million, or 12%, to $6.3 million in 1996 compared to 1995 due to a reduction in corporate staff after the U.S. Disposition. Additionally, 1996 included approximately $0.2 million in expenses for corporate staff who were retained until March 31, 1996. Net interest expense decreased $1.0 million, or 5%, in 1996 compared to 1995 as a result of lower average debt balance outstanding throughout 1996 with proceeds from the U.S. Disposition applied to reduce debt primarily in December 1995. Discontinued oil and gas operations includes both Canadian and United States oil and gas operations. Income from discontinued operations was $4.8 million in 1996 compared to $211,000 in 1995. Liquidity and Capital Resources On June 16, 1997, the Company completed the Canadian Disposition. Net proceeds after purchase price adjustments, transaction expenses and severance costs were approximately $91.3 million (C$126.7 million). With proceeds from the sale, the Company redeemed $49.2 million of its 12% Senior Notes, including redemption premium, during the third quarter of 1997, and on October 1, 1997, redeemed the remaining $7.5 million outstanding of 10-3/4% Subordinated Debentures at par. In addition, on December 30, 1997, the Company redeemed $25.6 million of its 12% Senior Notes, including redemption premium. In total, $79.9 million principal amount of debt was retired with sales proceeds. As of December 31, 1997, the Company had a debt to capitalization ratio of 56% compared to the highly leveraged percentage of 85% as of year-end 1996. On February 9, 1998, the Company issued $70 million of 9-1/8% Senior Notes (the "New Senior Notes") due 2006. On February 10, 1998, the Company called for redemption the remaining $24.6 million of its Senior Notes and $46 million of its Convertible Subordinated Debentures outstanding at December 31, 1997 (together, the "Redemptions"). The Company will use the net proceeds from the issuance of the New Senior Notes and available cash to fund the Redemptions. To the extent the holders of the Convertible Subordinated Debentures elect to convert their Convertible Subordinated Debentures into shares of the Company's common stock prior to redemption, a portion of the net proceeds will not be needed to effect such redemption. Depending on market conditions, the Company may use any such excess proceeds to repurchase shares of its common stock in the open market. Any remaining unused proceeds will be used for general corporate purposes. - 12 - At December 31, 1997, the Company had $21.7 million available in cash, $20 million available under the Frontier Credit Facility and $250,000 of 12% Senior Notes held by Wainoco. The Company had working capital of $20.9 million at December 31, 1997, including the portion of the sales proceeds from the Canadian Disposition remaining after debt retirement. Net cash provided by operating activities was $12.5 million, $8.5 million and $9.9 million for 1997, 1996 and 1995, respectively. Working capital changes required $9.9 million and $2.6 million of cash flows for 1997 and 1996, respectively. Consistent with the seasonality of its business, the Company invests in working capital during the first half of the year and recovers working capital investment in the second half of the year. Investing activities in 1997 included capital expenditures of $9.0 million, a decrease of $4.4 million from 1996, primarily due to a $5.4 million decrease in oil and gas operations investment. Investing activities include proceeds from the Canadian Disposition of $91.3 million for the year ended December 31, 1997. Capital expenditures were $13.4 for the year ended December 31, 1996 compared to $17.2 million in 1995. Refinery capital expenditures of $13 million are planned in 1998. It is anticipated that cash generated from operating activities will be sufficient to meet its 1998 investing requirements. The Company's 12% Senior Notes currently restrict it from the payment of dividends. Additionally, under certain conditions, the Frontier credit facility restricts the transfer of cash in the form of dividends, loans or advances to the Company from Frontier. Wainoco does not believe these restrictions limit its current operating plans. Other Matters IMPACT OF CHANGING PRICES/HEDGING The Company's revenues and cash flows, as well as estimates of future cash flows are very sensitive to changes in energy prices. Major shifts in the cost of crude and the price of refined products can result in large changes in operating margin from refining operations. Energy prices also determine the carrying value of the Refinery's inventory. The Company, at times, engages in futures transactions in its refining operations for the purpose of hedging its refining position. To date, the use of future transactions has been limited to protect against price declines for excess inventory volumes. Futures contracts and options may also, in the future, be used to fix margins in its refining and marketing operations. In addition, the Company, at times, engages in futures transactions for the purchase of natural gas at fixed prices. Natural gas is consumed by the Refinery for energy purposes. ENVIRONMENTAL Numerous local, state and federal laws, rules and regulations relating to the environment are applicable to the Company's operations. As a result, the Company falls under the jurisdiction of numerous state and federal agencies for administration and is exposed to the possibility of judicial or administrative actions for remediation and/or penalties brought by those agencies. Among these requirements are regulations recently promulgated by the EPA under the authority of Title III of the Clean Air Act Amendments. The Company estimates that the Title III regulations will require the Company to expend approximately $600,000 by the regulatory compliance deadline of August 1, 1998 to improve the Frontier Refinery's control of emissions of hazardous air pollutants. Subsequent rule making authorized by this or other titles of the Clean Air Act Amendments or similar laws may necessitate additional expenditures in future years. Because other refineries will be required to make similar expenditures, the Company does not expect such expenditures to materially adversely impact its competitive position. Frontier is party to one consent decree requiring the investigation and, in certain instances, mitigation of environmental impacts resulting from past operational activities. The Company has been and will be responsible for costs related to compliance with or remediations resulting from environmental regulations. There are currently no identified environmental remediation projects of which the costs can be reasonably estimated. However, the continuation of the present investigative process, other more extensive investigations over time or changes in regulatory requirements could result in future liabilities. The effects to the future consolidated financial position, results of operations or capital expenditures is unknown. - 13 - YEAR 2000 Many of the computer systems used by the Company today were designed and developed using two digits, rather than four, to specify the year. As a result, such systems will recognize the year 2000 as "00". This could cause many computer applications to fail completely or to create erroneous results unless corrective measures are taken. The Company utilizes software and related computer technology essential to its operations that may be affected by the Year 2000 issue. A review of the Company's primary computer accounting system indicated only minor modifications will be required to make it Year 2000 compliant. Reviews are being done to determine what actions will be necessary to make its remaining computer systems Year 2000 compliant. The Company expects to complete its remaining reviews and prepare cost estimates by mid-1998.

("Frontier"), collectively referred to as Wainoco or the Company. Wainoco is engaged in the crude oil refining and wholesale marketing of refined petroleum products business (the "refining operations"). Wainoco conducts its refining operations in the Rocky Mountain region of the United States. The Company's Cheyenne, Wyoming Refinery purchases the crude oil to be refined and markets the refined petroleum products produced, including various grades of gasoline, diesel fuel, asphalt and petroleum coke. Prior to the third quarter of 1997, Wainoco also explored for and produced oil and gas in Canada and prior to the first quarter of 1996 in the United States (together, the "oil and gas operations"). On June 16, 1997, Wainoco completed the sale of all its Canadian oil and gas properties. During the third quarter of 1994, the Company announced that it intended to cease all exploration activities in the United States and during 1995 completed the sale of its United States oil and gas assets. Operating results for Wainoco's oil and gas operations segment are presented as discontinued operations in the accompanying statements of operations and all previously reported results are restated to this presentation. 2 Significant Accounting Policies PROPERTY, PLANT AND EQUIPMENT Refinery plant and equipment is depreciated based on the straight-line method over estimated useful lives of three to twenty years. Maintenance and repairs are expensed as incurred except for major scheduled repairs and maintenance ("turnaround") of the Refinery operating units. The costs for turnarounds are ratably accrued over the period from the prior turnaround to the next scheduled turnaround. Major improvements are capitalized, and the assets replaced are retired. NEW ACCOUNTING STATEMENTS The Company adopted the Financial Accounting Standards Board's ("FASB") Statement of Financial Accounting Standard ("SFAS") No. 128, "Earnings Per Share" in 1997 which establishes new standards for computing and presenting earnings per share. SFAS No. 128 requires the presentation of basic and diluted earnings per share for each period presented. Earnings (loss) per share has been restated for periods presented to give effect for the adoption of SFAS No. 128. In June 1997, the FASB issued SFAS No. 130 "Reporting Comprehensive Income" which establishes standards for reporting and displaying comprehensive income and its components in the financial statements. SFAS No. 130 is effective for fiscal years beginning after December 15, 1997. The adoption of this statement requires incremental financial statement disclosures and thus will have no effect on the Company's financial position or results of operations. INVENTORIES Inventories of crude oil, other unfinished oils and all finished products are recorded at the lower of cost on a first-in, first-out (FIFO) basis or market. Refined product exchange transactions are considered asset exchanges with deliveries offset against receipts. The net exchange balance is included in inventory. Inventories of materials and supplies are recorded at cost. SCHEDULE OF COMPONENTS OF INVENTORY (In thousands) December 31, 1997 1996 --------- --------- Crude oil $ 3,904 $ 2,863 Unfinished products 6,338 7,024 Finished products 9,929 12,816 Chemicals 1,534 851 Repairs and maintenance supplies and other 5,961 6,063 --------- --------- $ 27,666 $ 29,617 ========= ========= ENVIRONMENTAL EXPENDITURES Environmental expenditures are expensed or capitalized based upon their future economic benefit. Costs which improve a property's pre-existing condition and costs which prevent future environmental contamination are capitalized. Costs related to environmental damage resulting from operating activities subsequent to acquisition are expensed. Liabilities for these expenditures are recorded when it is probable that obligations have been incurred and the amounts can be reasonably estimated. - 21 - HEDGING The Company, at times, engages in futures transactions in its refining operations for the purpose of hedging its inventory position and natural gas prices. Gains and losses on futures contracts designated as hedges are recognized in refining operating costs when the associated hedge transaction is consummated. The Company does not enter into derivative contracts for speculative purposes. INTEREST Interest is reported net of interest capitalized and interest income. Interest income of $2.0 million, $109,000 and $140,000 was recorded in the years ended December 31, 1997, 1996 and 1995, respectively. During 1996, the Company capitalized interest of $24,000. Wainoco capitalizes interest on debt incurred to fund the construction or acquisition of a significant asset. Additionally, to manage its interest cost and exposure to interest rate movements, the Company, at times, enters into interest rate swaps. Such agreements effectively change the Company's interest rate exposure. At December 31, 1997, the Company was not subject to any such agreements. STOCK BASED COMPENSATION Compensation cost is measured using the intrinsic value method. Under this method, compensation cost is the excess, if any, of the quoted market value of the Company's common stock at the grant date over the amount the employee must pay to acquire the stock. No compensation cost was recognized for the years ended December 31, 1997, 1996 and 1995. CURRENCY TRANSLATION The Canadian dollar financial statements of the Canadian oil and gas operations have been translated to United States dollars. Gains and losses on currency transactions are included in the consolidated statements of operations currently, and translation adjustments are included in the consolidated statements of shareholders' equity. See Note 3 for information relating to the recognition of the cumulative translation adjustment in 1997. INTERCOMPANY TRANSACTIONS Significant intercompany transactions are eliminated in consolidation. USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. CASH FLOW REPORTING Highly liquid investments with a maturity, when purchased, of three months or less are considered to be cash equivalents. Cash payments for interest during 1997, 1996 and 1995 were $18.4 million, $16.3 million and $18.8 million, respectively. Cash payments for income taxes during 1997, 1996 and 1995 were $930,000, $187,000 and $133,000, respectively. 3 Sale of Oil and Gas Operations On June 16, 1997, Wainoco completed the sale of all its Canadian oil and gas properties. The transaction was initiated by the Company through a negotiated bid process in order to maximize shareholder value. The oil and gas assets were located in British Columbia and Alberta and included approximately 94 billion cubic feet of natural gas, 1.7 million barrels of oil, condensate and natural gas liquids, 121,500 net undeveloped leasehold acres and a significant amount of seismic data. Additionally, value was received for certain Canadian income tax pools of the Company. The contract purchase price of C$133.6 million was adjusted from the January 1, 1997 effective date of the sale to June 16, 1997. Net proceeds after these adjustments, transaction expenses and severance costs were approximately C$126.7 million (US$91.3 million) as of June 16, 1997. A net gain of $23.3 million was realized on the transaction. No Canadian taxes are estimated to be payable due to available oil and gas deductions and net operating loss carryforwards. For U.S. federal income taxes, available net operating loss carryforwards will be utilized to offset the gain; however, alternative minimum taxes of approximately $800,000 are estimated and have been paid. - 22 - The cumulative translation adjustment as of May 5, 1997 (the measurement date of the sale) of $9.9 million was realized against income as a result of the sale. In prior periods, Wainoco had recognized the currency translation impact of its Canadian operations as a direct reduction to shareholders' equity. Consequently, the recognition of the cumulative translation adjustment in the accompanying statements of operations has no effect on shareholders' equity. A net loss of $54,000 from Canadian operations from the measurement date until June 16, 1997 was included in the gain calculation. As of December 31, 1997, the assets and liabilities of the Canadian operations retained by Wainoco were not material. In the fourth quarter of 1995, Wainoco culminated the restructuring of exploration activities in the United States and sold its last domestic oil and gas assets. The following schedule presents certain discontinued oil and gas operating income (loss) information and capital expenditures for the three years ended December 31, 1997, 1996 and 1995 and identifiable assets as of December 31, 1997, 1996 and 1995: (in thousands) December 31, 1997 1996 1995 --------- --------- --------- Oil and gas sales Canada $ 7,280 $ 19,592 $ 21,096 United States - 987 9,696 Depreciation, depletion and amortization Canada 3,002 8,123 9,641 United States - - 3,299 Operating income (loss) Canada 1,954 4,129 2,737 United States - 987 (623) Capital expenditures Canada 2,815 7,917 10,865 United States - - 277 Identifiable assets Canada - 74,001 75,229 United States - - - 4 Long-term Debt SCHEDULE OF LONG-TERM DEBT (in thousands) December 31, 1997 1996 --------- --------- Refining credit facility $ - $ - 12% Senior Notes 24,572 95,000 7-3/4% Convertible Subordinated Debentures 46,000 46,000 10-3/4% Subordinated Debentures - 7,428 --------- --------- 70,572 148,428 Less current maturities - 2,500 --------- --------- $ 70,572 $ 145,928 ========= ========= REFINING CREDIT FACILITY The refining operations has a working capital credit facility with a group of three banks which expires on April 2, 1999. The facility is a collateral-based facility with total capacity of up to $50 million, of which maximum cash borrowings are $20 million. Any unutilized capacity after cash borrowings is available for letters-of-credit. No debt was outstanding on this facility at December 31, 1997 and 1996. Standby letters of credit outstanding were $4.5 million and $19.5 million at December 31, 1997 and 1996, respectively. The facility provides working capital financing for operations, generally the financing of crude and product supply. It is generally secured by Frontier's current assets. The agreement provides for a quarterly commitment fee of .375 of 1% per annum. Interest rates are based, at the Company's option, on the agent bank's prime rate plus 1/2% or the reserve-adjusted LIBOR plus 1-3/4%. Standby letters-of-credit issued bear a fee of 1-1/4% annually, plus standard issuance and renewal fees. The facility agreement includes certain financial covenant requirements relating to Frontier's working capital, cash earnings, tangible net worth and fixed charge coverage. SENIOR NOTES The $24.6 million of unsecured 12% Senior Notes ("Senior Notes") are due 2002. The notes are redeemable, at the option of the Company, at a premium of 103.43% after July 31, 1997, declining to 100% in 1999. Interest is payable semiannually. See Note 9 for information related to the December 31, 1997 debt balance and activity subsequent thereto. - 23 - CONVERTIBLE SUBORDINATED DEBENTURES The $46 million of 7-3/4% Convertible Subordinated Debentures ("Convertible Subordinated Debentures") are due in 2014. The debentures are convertible into the Company's common stock at $8.75 per share. Interest is payable semiannually. The debentures are redeemable at a premium of 102.325% declining to 100% in 1999. Sinking fund payments of 5% of the principal amount commence in 2000, and are calculated to retire 70% of the principal amount prior to maturity. See Note 9 for information related to the December 31, 1997 debt balance and activity subsequent thereto. EARLY RETIREMENT OF DEBT On July 21, 1997, the Company initiated a tender offer for $91.4 million of its Senior Notes at a price of par as required by the Senior Notes Indenture after a material sale of assets. The par tender offer expired on August 20, 1997 with approximately $2.2 million being acquired by the Company. On August 21, 1997, the Company called $48.0 million principal amount of its Senior Notes (including approximately $2.5 million held by the Company) at a price of 103.43% and redeemed them on September 23, 1997. The Company called all $7.5 million principal amount of 10-3/4% Subordinated Debentures and redeemed them on October 1, 1997. In addition, on November 25, 1997 the Company called $25.0 million principal amount of its Senior Notes (including approximately $.3 million held by the Company) at a price of 103.43% and redeemed them on December 30, 1997. The debt redemptions were funded with proceeds from the sale of the Canadian oil and gas operations as disclosed in Note 3. Based on the redemptions, the Company has recognized an extraordinary loss, net of taxes, of approximately $3.9 million due to the redemption premium of 103.43% on the Senior Notes and reduction in debt issuance costs. RESTRICTIONS ON LOANS, TRANSFER OF FUNDS AND PAYMENT OF DIVIDENDS The Frontier credit facility restricts Frontier as to the distribution of capital assets and the transfer of cash in the form of dividends, loans or advances when there are any outstanding borrowings under the facility or when a default exists or would occur. FIVE-YEAR MATURITIES The estimated five-year maturities of long-term debt are none in 1998 and 1999, $2.3 million in 2000 and 2001, and $26.9 million in 2002. 5 Income Taxes The following is the provision (benefit) for income taxes for the three years ended December 31, 1997, 1996 and 1995.

As a result of the Company's history of operating losses, a valuation allowance has been provided for deferred tax assets that are not offset by scheduled future reversals of deferred tax liabilities. At December 31, 1997, the Company had regular net operating loss ("NOL") carryforwards for United States tax reporting purposes of $145.6 million available to reduce future federal taxable income. The regular NOL carryforwards will expire as follows: $32.2 million in 2002, $7.7 million in 2003, $11.3 million in 2004, $29.5 million in 2005, $17.2 million in 2006, $13.7 million in 2007, $11.3 million in 2008, $2.2 million in 2009, $16.1 million in 2010 and $4.4 million in 2011. Also at December 31, 1997, the Company had alternative minimum tax net operating loss ("AMT NOL") carryforwards for United States tax reporting of $98.4 million to reduce future taxable income. The AMT NOL carryforwards will expire as follows: $2.8 million in 2002, $5.4 million in 2003, $9.0 million in 2004, $27.0 million in 2005, $13.1 million in 2006, $11.6 million in 2007, $8.6 million in 2008, $1.4 million in 2009, $16.8 million in 2010 and $2.7 million in 2011. The Company has tax depletion carryforwards of $8.7 million which are indefinitely available to reduce future United States income taxes payable. As of December 31, 1996, the Company had net operating loss carryforwards for Canadian tax reporting purposes of $2.1 million which expire in 2003. The Company also had oil and gas deductions of $116.7 million and earned depletion of $8.6 million which are available indefinitely to reduce future taxable income. In June 1997, these tax benefits were acquired by the purchaser of the Canadian oil and gas properties. 6 Common Stock EARNINGS PER SHARE The following is a reconciliation of the numerators and denominators used in the calculation of basic and diluted earnings per share ("EPS") for income (loss) from continuing operations for the years ended December 31, 1997, 1996 and 1995. 1997 1996 1995 ----------------------------------- ----------------------------------- ----------------------------------- (In thousands, except per share Income Shares Per Share Income Shares Per Share Income Shares Per Share amounts) (Numerator) (Denominator) Amount (Numerator) (Denominator) Amount (Numerator) (Denominator) Amount ----------- ------------- --------- ----------- ------------- --------- ----------- ------------- --------- Basic EPS Income (loss) from continuing operations $ 7,812 27,457 $ .28 $ (11,644) 27,257 $ (.43) $ (19,336) 27,256 $ (.71) Dilutive securities Stock options - 494 - - - - Dilutive EPS Income (loss) from continuing operations $ 7,812 27,951 $ .28 $ (11,644) 27,257 $ (.43) $ (19,336) 27,256 $ (.71) - 25 - NON-EMPLOYEE DIRECTORS STOCK GRANT PLAN During 1995, the Company established a stock grant plan for non-employee directors. The purpose of the plan is to provide a portion of non-employee directors compensation in Company stock. The plan will be beneficial to the Company and its stockholders by allowing non-employee directors to have a personal financial stake in the Company through an ownership interest in the Company's common stock. The plan may grant an aggregate of 60,000 shares of the Company's common stock initially held in treasury. The Company made grants to directors under this plan of 2,500 shares in 1997, 1996 and 1995. STOCK OPTION PLANS Wainoco has three stock option plans which authorize the granting of restricted stock and options to purchase shares. The plans through December 31, 1997 have reserved for issuance a total of 4,282,700 shares of common stock of which 2,364,675 shares were granted and exercised, 1,656,340 shares were granted and were outstanding and 261,685 shares were available to be granted. Options under the plans are granted at not less than fair market value on the date of grant. No entries are made in the accounts until the options are exercised, at which time the proceeds are credited to common stock and paid-in capital. Generally, the options vest ratably throughout their five-year terms. A summary of the status of the Company's plans as of December 31, 1997, 1996 and 1995, and changes during the years ended on those dates is presented below. 1997 1996 1995 ---------------------- ---------------------- ---------------------- Weighted- Weighted- Weighted- Average Average Average Number Exercise Number Exercise Number Exercise of Options Price of Options Price of Options Price ---------- --------- ---------- --------- ---------- --------- Outstanding at beginning of year 2,331,904 $ 3.81 2,332,842 $ 4.32 1,858,447 $ 4.84 Granted 742,800 4.74 981,229 3.31 760,500 4.34 Exercised (797,787) 3.89 - - (2,660) 3.50 Reissued - - (669,229) 4.30 (129,400) 7.39 Expired (620,577) 3.48 (312,938) 4.53 (154,045) 5.55 ---------- --------- ---------- --------- ---------- --------- Outstanding at end of year 1,656,340 4.31 2,331,904 3.81 2,332,842 4.32 ---------- --------- ---------- --------- ---------- --------- Exercisable at end of year 940,850 4.14 1,526,561 4.04 1,707,312 4.41 ---------- --------- ---------- --------- ---------- --------- Available for grant at end of year 261,685 68,208 119,720 ---------- ---------- ---------- Weighted-average fair value of options granted during the year 1.51 .65 1.04 The following table summarizes information about stock options outstanding at December 31, 1997: Options Outstanding Options Exercisable ------------------------------------------------- ------------------------------ Number Weighted-Average Weighted- Outstanding Remaining Weighted-Average Exercisable Weighted-Average Range of exercise prices at 12/31/97 Contractual Life Exercise Price at 12/31/97 Exercise Price ----------- ---------------- ---------------- ----------- ---------------- $2.88 to $7.82 1,656,340 3.23 $ 4.31 940,850 $ 4.14 Had compensation costs been determined based on the fair value at the grant dates for awards made in 1997, 1996 and 1995, the Company's net income (loss) and income (loss) per share would have been the pro forma amounts indicated on the following page for the years ended December 31, 1997, 1996 and 1995. - 26 - (In thousands, except per share amounts) 1997 1996 1995 --------- --------- --------- Net income (loss): As reported $ 19,055 $ (6,892) $ (19,125) Pro forma 18,578 (7,263) (19,316) Basic and diluted income (loss) 	per share:				 As reported $ .69 $ (.25) $ (.70) Pro forma .67 (.27) (.71) The fair value of grants was estimated on the date of grant using the Black-Scholes option pricing model with the following weighted-average assumptions used: risk-free interest rates of 5.91%, 5.33% and 6.54%, expected volatilities of 41.07%, 32.95% and 38.11%, expected lives of 2.32, 1.59 and 1.93 years and no dividend yield in 1997, 1996 and 1995, respectively. 7 Commitments and Contingencies LEASE AND OTHER COMMITMENTS Wainoco has noncapitalized building, equipment and vehicle lease agreements which expire from 1998 through 2005 having minimum annual payments as of December 31, 1997 of $2.5 million for 1998, $3.9 million for 1999, $489,000 for 2000, $396,000 for 2001, $202,000 for 2002, $42,000 each for 2003 and 2004 and $25,000 in 2005. Operating lease rental expense was $2.6 million, $1.7 million and $1.7 million for the three years ended December 31, 1997, 1996 and 1995, respectively. The Company has contracted for pipeline capacity of approximately 13,800 bpd on the Express Pipeline from Hardisty, Alberta to Guernsey, Wyoming commencing in 1997 for a period of 15 years. The Company's commitment for pipeline capacity is approximately $5.8 million per year. The agreement allows the Company to assign a portion of its capacity in early years for additional capacity in later years. The Company also has commitments to purchase crude oil from various suppliers to meet its Refinery throughput requirements. CONCENTRATION OF CREDIT RISK The Company has concentrations of credit risk with respect to sales within the same or related industry and within limited geographic areas. The Refining operation sells its products exclusively at wholesale, principally to independent retailers and major oil companies located primarily in the Denver, western Nebraska and eastern Wyoming regions, with 13% of its customers accounting for approximately 66% of total refined product sales in 1997. Wainoco extends credit to its customers based on ongoing credit evaluations. An allowance for doubtful accounts is provided based on the current evaluation of each customer's credit risk, past experience and other factors. During 1997, the Company made sales to CITGO Petroleum Products of approximately $72 million, which accounted for 19% of consolidated revenues. CONTRIBUTION PLANS Wainoco sponsors separate defined contribution plans for employees covered by a collective bargaining agreement and employees not covered by such an agreement. All employees may participate by contributing a portion of their annual earnings to the plans. The Company makes basic and/or matching contributions on behalf of participating employees. The cost of the plans for the three years ended December 31, 1997, 1996 and 1995 was $1.3 million, $1.2 million and $1.4 million, respectively. ENVIRONMENTAL Wainoco accrues for environmental costs as indicated in Note 1. Numerous local, state and federal laws, rules and regulations relating to the environment are applicable to the Company's operations. As a result, the Company falls under the jurisdiction of numerous state and federal agencies and is exposed to the possibility of judicial or administrative actions for remediation and/or penalties brought by those agencies. Frontier is party to one consent decree requiring the investigation and, in certain instances, mitigation of environmental impacts resulting from past operational activities. The Company has been and will be responsible for costs related to compliance with or remediations resulting from environmental regulations. There are currently no identified environmental remediation projects of which the costs can be reasonably estimated. However, the continuation of the present investigative process, other more extensive investigations over time or changes in regulatory requirements could result in future liabilities. LITIGATION The Company is involved in various lawsuits which are incidental to its business. In management's opinion, the adverse determination of - 27 - such lawsuits would not have a material adverse effect on the Company's financial position or results of operations. COLLECTIVE BARGAINING AGREEMENT EXPIRATION Wainoco's refining unit hourly employees are represented by seven bargaining units, the largest being the Oil, Chemical and Atomic Workers International Union ("OCAW"). Six AFL-CIO affiliated unions represent the craft workers. In July 1996, the Company concluded new bargaining agreements, with the three-year OCAW agreement to expire in July 1999, while the six-year AFL-CIO contract expires in June 2002. The union employees represent approximately 58% of the Company's work force at December 31, 1997. 8 Fair Value of Financial Instruments The fair value of the Company's Senior Notes, Convertible Subordinated Debentures and 10-3/4% Subordinated Debentures was estimated based on quotations obtained from broker-dealers who make markets in these and similar securities. The bank credit facilities are based on floating interest rates and, as such, the carrying amount is a reasonable estimate of fair value. At December 31, 1997 and 1996, the carrying amounts of long-term debt instruments (including current maturities) were $70.6 million and $148.4 million, respectively, and the estimated fair values were $72.0 million and $145.0 million. As of December 31, 1997, the Company had entered into futures contracts to hedge a portion of its natural gas consumption requirements. The futures contracts are placed with a major financial institution the Company believes is a minimum credit risk. The futures contracts mature each month through April 1998. The fair value of the Company's open natural gas futures contract at December 31, 1997 was $(281,000). 9 Subsequent Event DEBT REFINANCING February 9, 1998, the Company issued $70 million of 9-1/8% Senior Notes (the "New Senior Notes") due 2006. On February 10, 1998, the Company called for redemption the remaining $24.6 million of its Senior Notes and $46 million of its Convertible Subordinated Debentures outstanding at December 31, 1997 (together, the "Redemptions"). The Company will use the net proceeds from the issuance of the New Senior Notes and available cash to fund the Redemptions.
