The following summary highlights information contained elsewhere in this document. It does not contain all of the information you should consider before investing in the notes. You should read this entire prospectus carefully. Overview Port Arthur Coker Company was formed as a Delaware limited partnership in May 1999 to develop, construct, own, operate and finance a new 80,000 barrel per stream day delayed coking unit, a 35,000 barrel per stream day hydrocracker and a 417 long tons per day sulfur complex and related assets currently under construction at the Port Arthur, Texas refinery of our affiliate Clark Refining & Marketing, Inc. In this prospectus, we refer to this equipment, collectively with all of its associated contracts and infrastructure, as our coker project. Our coker project is part of a coordinated project with Clark Refining & Marketing and Air Products and Chemicals, Inc. We refer to these coordinated projects collectively in this prospectus as the refinery upgrade project. The Clark Refining & Marketing portion of the refinery upgrade project includes modifications to their crude unit and hydrotreaters. Clark Refining & Marketing will lease these units to us. In this prospectus, we refer to these leased units, together with our coker project, as our heavy oil processing facility. The Air Products portion of the refinery upgrade project consists of a new hydrogen supply plant that will supply hydrogen for our heavy oil processing facility. Our heavy oil processing facility will upgrade lower-cost heavy sour crude oil into higher-value refined products. The following diagram illustrates the various projects to be completed as part of the refinery upgrade project. [REFINERY UPGRADE PROJECT CHART] 1 The following is a description of the major processing units that are being constructed or modified as part of the refinery upgrade project: crude unit The crude unit and vacuum tower will be upgraded so that they will have the capacity to process more and heavier crude oil by separating it into components that include light gases, kerosene, gas oil and a residue called vacuum tower bottoms, all of which require additional processing at the refinery before becoming commercially saleable. delayed The new coker will convert vacuum tower bottoms from the coking unit processing of heavy sour crude oil by the refinery's crude unit into lighter products such as fuel gas, propane, butane, gasoline, diesel, lightcycle oil and gas oil, all of which require additional processing, and petroleum coke, which can be sold commercially. vacuum gas oil The new hydrocracker will employ catalyst and hydrogen at hydrocracker elevated temperatures and pressure to convert gas oil from our new coking unit and other processing units at the refinery into lighter products and high quality vacuum gas oil, which are commercially saleable. hydrotreaters The hydrotreaters will be upgraded so that they will have increased capacities to remove nitrogen and sulfur from kerosene, diesel and other products produced by the refinery's coking, crude and other units. This process of hydrotreating turns these products into commercially saleable finished products. sulfur complex The new sulfur recovery unit will process the incremental sulfur that results from the processing of heavy sour crude oil and will operate in conjunction with an existing sulfur recovery unit at the refinery. Port Arthur Finance Corp., a wholly owned subsidiary of Port Arthur Coker Company, was incorporated in Delaware in July 1999 for the purpose of issuing the outstanding notes and borrowing under our bank credit facilities, as agent on behalf of Port Arthur Coker Company, and transferring the proceeds of the issuance of notes and borrowing under our bank credit facilities to Port Arthur Coker Company by means of an intercompany note. Port Arthur Coker Company is using the proceeds to fund a portion of the costs of the development and construction of our coker project. Port Arthur Coker Company is owned 1% by its general partner, Sabine River Holding Corp., and 99% by its limited partner, Neches River Holding Corp. Both partners were incorporated in Delaware in May 1999. Each of Port Arthur Coker Company, Sabine River and Neches River have unconditionally guaranteed, on a joint and several basis, all the obligations of Port Arthur Finance under the outstanding notes and will unconditionally guarantee, on a joint and several basis, all the obligations of Port Arthur Finance under the exchange notes. 2 Planned Ownership Structure [Flowchart of Ownership Structure] Sabine River is owned 90% by Clark Refining Holdings Inc. and 10% by Occidental Petroleum Corporation. After giving effect to the full $135 million of equity contributions to be made in connection with our coker project, Clark Refining Holdings will be owned, indirectly through subsidiaries, by Blackstone Capital Partners III Merchant Banking Fund L.P. and its affiliates with an approximately 82% interest, and by Occidental with an approximately 17% interest. We are an affiliate of Clark Refining & Marketing because Clark Refining Holdings owns 100% of the capital stock of Clark USA, Inc., which in turn owns 100% of the capital stock of Clark Refining & Marketing. We and our contractual arrangements have been structured in a manner designed not to be consolidated with Clark Refining Holdings, Clark USA or Clark Refining & Marketing in a bankruptcy of any of these entities. As such, you will have recourse only to us, Sabine River and Neches River and not to any of our other direct or indirect owners with respect to our obligations on the notes. We believe that this structure enhances the credit quality of our notes because our assets, which are mortgaged to secure the notes, should remain separate from the assets of Clark Refining & Marketing and Clark Refining Holdings in the event either of those entities were to seek reorganization in bankruptcy. Our principal executive offices are located at 1801 S. Gulfway Drive, Office No. 36, Port Arthur, Texas 77640. Our telephone number is (409) 982-7491. 3 Our Coker Project Rationale for Our Coker Project. Blackstone and Clark Refining Holdings have been pursuing a strategy of positioning Clark Refining Holdings as a leading independent refiner in the United States by selectively increasing its refining capacity through acquiring refining assets, improving the productivity of its existing refineries and divesting non-core assets. This strategy is subject to costs, industry and financial market risks, operating risks and risk of increased competition for available assets, among other risks, that may cause Blackstone and Clark Refining Holdings to be unsuccessful in implementing such a strategy. The refinery upgrade project is an important element of this strategy. Purvin & Gertz, the independent engineer, expects that the refinery upgrade project will transform the Port Arthur refinery into one of the five most competitive refineries on the U.S. Gulf Coast. The refinery upgrade project was initiated for the following reasons: . Port Arthur refinery's suitability for a heavy oil upgrade. Clark Refining Holdings believes the Port Arthur refinery is well-suited to be upgraded to process significantly more heavy sour crude oil. Its Gulf Coast location is close to the major heavy sour crude oil producers and permits waterborne deliveries of oil. In addition, because the Port Arthur refinery was originally designed and operated as a much larger facility with over 400,000 barrels per day of crude oil throughput capacity, the refinery has the scale, processing capability and much of the infrastructure including docks, storage tanks, steam and power generation capability and wastewater treatment facilities to support an upgraded operation. As a result, Clark Refining Holdings believes the refinery upgrade project can be undertaken at a lower capital cost than at many other U.S. Gulf Coast refineries. . Crude oil cost reduction. Clark Refining Holdings expects to be able to reduce crude oil costs at the Port Arthur refinery by increasing the quantities of heavy sour crude oil processed at the Port Arthur refinery from 20% to 80% of capacity. Heavy sour crude oil typically sells at a discount when compared with light sweet crude oil because heavy sour crude oil is more difficult to process. . Increased cash flow. Purvin & Gertz expects us to generate approximately $228 million of annual average operating cash flows over the initial 11- year operating period of our coker project. Clark Refining Holdings expects Clark Refining & Marketing also to generate incremental cash flow as a result of the refinery upgrade project. Purvin & Gertz's projection is subject to assumptions and an alternative conclusion could be reached using different assumptions. See Annex B to this prospectus for a discussion of the material assumptions underlying Purvin & Gertz's projection. . Margin support. We believe we will benefit from a coker gross margin support mechanism in our long term crude oil supply agreement with P.M.I. Comercio Internacional, a subsidiary of Petroleos Mexicanos, also known as PEMEX, the Mexican national oil company and guarantor of P.M.I. Comercio Internacional's obligations. This mechanism is designed to moderate the fluctuations of our coker gross margin, which is the differential between the price for intermediate refined products from our coking operations and the cost of coker feedstocks. The term intermediate refined products is used in the oil industry to refer to petroleum products that are generally considered to need additional refining prior to becoming commercially saleable and the term feedstocks is generally used to refer to the raw materials needed for a refinery processing unit to produce a particular refined product. This mechanism is based on a formula that is intended to be an approximation for coker gross margin and is designed to provide for a minimum average coker gross margin over the first eight years following completion of the refinery upgrade project. Purvin & Gertz believes the mechanism will serve as a suitable method of stabilizing our coker gross margin fluctuations and that the mechanism equates to an approximate $5.94 heavy/light differential when applied to 1987 to 1998 prices. General Description. The refinery upgrade project will allow our heavy oil processing facility to process an average of 200,000 barrels per stream day of crude oil. At least 150,000 barrels per stream day of heavy sour crude oil will be purchased from P.M.I. Comercio Internacional under our long term crude oil supply agreement. All of the output of our heavy oil processing facility will be purchased by our affiliate, Clark Refining & Marketing, under a long term product purchase agreement. We expect construction of our coker project and the entire refinery upgrade project to be mechanically complete around November 2000, and we expect to begin commercial operation around January 2001. 4 Key Project Contracts. The chart below depicts some of the key contracts relating to the construction and operation of our coker project and our heavy oil processing facility which are described in more detail below. [Flow chart of Key Coker Project Contracts and parties thereto] Construction of Our Coker Project. We entered into a contract for the engineering, procurement and construction of our coker project with Foster Wheeler USA Corporation in July 1999. Foster Wheeler Corporation, the parent of Foster Wheeler USA, has guaranteed Foster Wheeler USA's payment and performance obligations under this construction contract. Under this construction contract, Foster Wheeler USA will continue to engineer, design, procure equipment for, construct, test and oversee start-up of our coker project and integrate our coker project with the Port Arthur refinery. Under the construction contract, we will pay Foster Wheeler USA a fixed price of approximately $544 million of which $157.1 million was credited to us for amounts Clark Refining & Marketing had already paid Foster Wheeler USA for work performed on our coker project prior to August 1999. We purchased this work in progress from Clark Refining & Marketing when we issued the outstanding notes. Our construction contract does not cover the work to be undertaken by Clark Refining & Marketing as part of the refinery upgrade project. Clark Refining & Marketing has contracted separately with Foster Wheeler USA to perform the majority of such work. Under our construction contract, Foster Wheeler USA must demonstrate that our coker project is mechanically complete and ready for start-up by March 2001. In addition, Foster Wheeler USA must fulfill all its obligations under the construction contract and demonstrate achievement of specified guarantees of capacity and reliability for our coker project by December 2001. If Foster Wheeler USA demonstrates achievement of mechanical completion of our coker project prior to our target date of November 2000, it will receive an early completion bonus. If our coker project is not mechanically complete and ready for start-up by January 2001 or Foster Wheeler USA has not demonstrated achievement of 100% of its guarantee of reliability for our coker project by that date, it must pay us delay damages. The amount of these delay damages is capped at $70 million. In 5 addition, if Foster Wheeler USA fails to demonstrate achievement of 100% of its capacity and reliability guarantees for our coker project, it still may fulfill its obligations under the construction contract by making specified buydown payments to us, if Foster Wheeler USA demonstrates achievement of 95% of their reliability guarantee for our coker project and specified minimum capacities for each of our new units. These buydown payments are capped at $75 million. Foster Wheeler USA may be liable for damages under the construction contract up to 100% of the contract price. This liability cap, however, does not apply to damages arising out of Foster Wheeler USA's indemnification obligations. Work on our coker project is well advanced. As of January 2000, 100% of major equipment procurement, 89% of total materials procurement and 98% of detailed design and engineering were complete and construction was 31% complete. Construction activities to date have included site preparation, foundations and footings installation, major equipment installation and pipe rack construction. In June 1999, the six coke drums for our new delayed coking unit arrived at the Port Arthur refinery and by October 1999 were all installed in their support structures. In January 2000, approximately 175 people were working on design and engineering and approximately 965 people are working on construction of our coker project. As part of the refinery upgrade project, Air Products will construct and own a new hydrogen supply plant at the Port Arthur refinery on land leased from Clark Refining & Marketing. This new hydrogen supply plant is designed to supply hydrogen to us, as well as hydrogen, steam and electricity to Clark Refining & Marketing, for use at the Port Arthur refinery. Air Products is obligated to ensure that the hydrogen supply plant is ready to operate no later than December 2000, the date when we expect our heavy oil processing facility to first need hydrogen. Our Operations. Clark Refining & Marketing has agreed to provide us with services necessary to complete our coker project and to operate the heavy oil processing facility. Under our services and supply agreement, the services to be performed by Clark Refining & Marketing include, among others, the following: . oversight of the construction of our new units and other equipment and performance of our obligations under our construction contract with Foster Wheeler USA, other than our payment obligations; . operation and maintenance of the ancillary units and equipment that we are leasing from Clark Refining & Marketing; . management of the operation and maintenance of our new processing units and other equipment at the Port Arthur refinery; . management of our crude oil purchases and transportation of our crude oil to the Port Arthur refinery; and . supply of other required feedstocks, materials and utilities. In addition, under our services and supply agreement Clark Refining & Marketing has a right of first refusal to require us to process crude oil for them in an amount equal to approximately 20% of the processing capacity of our heavy oil processing facility. We and Clark Refining & Marketing will receive fees from each other for providing services. The actual fee and how it will be recorded will vary based on the type of service provided. Some fees will be based on a sharing of costs while others will include profit margin, but such fees were intended to approximate fair market value in the aggregate. Fees will be capitalized, expensed or charged to cost of goods sold, as appropriate. Our Supply of Crude Oil. We expect to receive the heavy sour crude oil to be processed by our heavy oil processing facility from P.M.I. Comercio Internacional under our long term crude oil supply agreement. Petroleos Mexicanos, the parent of P.M.I. Comercio Internacional, which is often referred to in the oil industry as PEMEX, has guaranteed P.M.I. Comercio Internacional's obligations under our long term crude oil supply 6 agreement. The type of Mexican heavy sour crude oil available to us under our long-term oil supply agreement is called Maya. Our long term crude oil supply agreement includes a mechanism designed to minimize the effect of adverse refining cycles and to moderate the fluctuations of our coker gross margin. This mechanism contains a formula that is intended to be an approximation for coker gross margin and is designed to provide for a minimum average coker gross margin over the first eight years following completion of the refinery upgrade project, if it is completed by July 2001. This eight year period will be shortened by any period of delay in completion of the refinery upgrade project beyond July 2001 unless the delay is caused by events beyond our reasonable control. Sale of Our Refined Products. We have entered into a product purchase agreement with Clark Refining & Marketing for the sale of all refined and intermediate products produced by our heavy oil processing facility. Under our product purchase agreement, Clark Refining & Marketing is obligated to accept and pay for all our products and has a limited right to request that we produce a specified mix of products. The prices that we are paid for our products by Clark Refining & Marketing are determined by formulas that are based on published market benchmark prices, as they may vary from time to time. We believe that the pricing mechanism reflects an arm's-length fair market price between us and Clark Refining & Marketing. These prices are determined at the time of delivery to Clark Refining & Marketing, so we bear the market risk of any change in the relative prices of Maya and our other feedstocks and the prices of our products during the time that we are refining the crude oil. Independent Engineer's Report. Purvin & Gertz, Inc., in its role as independent engineer, prepared a report dated August 10, 1999, which discusses certain technical, environmental and economic aspects of the Refinery Upgrade Project. This report is set forth in its entirety as Annex B to this prospectus and a summary of the report is included under "Independent Engineer's Report Summary." This report includes, among other things, Purvin & Gertz's projections of operating results, including projected revenues, expenses and debt service coverage ratios during the period the notes are scheduled to remain outstanding, a design basis review of our coker project and the Port Arthur refinery and a review of our principal project contracts. In addition, the report contains a discussion of whether, and the extent to which, we would be able to operate on a "stand-alone" basis without our services and supply agreement and product purchase agreement with Clark Refining & Marketing. Crude Oil and Refined Product Market Report. In addition, Purvin & Gertz, in its role as our independent marketing consultant, prepared a crude oil and refined product market forecast report dated July 13, 1999. This report includes price forecasts for crude oil and refined products, and discusses the effect on our coker project of fluctuations in heavy sour crude oil availability, the costs of heavy sour crude oil and the prices at which refined products may be sold. This report is set forth in its entirety as Annex C to this prospectus and a summary of Purvin & Gertz's report is included under "Crude Oil and Refined Product Market Report Summary." 7 Our Financing Plan We estimate that we will need approximately $715 million to pay all of the costs of developing, constructing, financing and commissioning our coker project. Of this amount, approximately $255 million has been raised from the sale of the outstanding notes which bear interest at a fixed rate of 12.5% per year, approximately $325 million will come from our secured construction and term loan facility provided by commercial banks and institutional lenders and approximately $135 million will come from equity contributions by Blackstone and Occidental. The construction and term loan facility is split into a Tranche A of $225 million, at a variable rate equal to LIBOR plus 4.75%, with a term of 7.5 years and a Tranche B of $100 million, at an interest rate of LIBOR plus 5.25%, with a term of 8 years. Our contractual arrangements with Blackstone and Occidental provide that the aggregate $135 million equity commitment will be funded pro rata with the funding of our notes and bank term debt, so that at the time of each advance of debt and equity to pay our construction costs the amount funded will be approximately 65% debt and 35% equity. As of February 29, 2000, approximately $61 million of the $135 million of equity had been funded. We expect the remaining $74 million of equity to be funded by March 2001. The following table set forth our expected sources and uses of funds. Amounts ------------------------ (in millions of dollars) Sources Construction and term loans......................... $325 The outstanding notes............................... 255 Equity contributions................................ 135 ---- Total Sources......................................... $715 ==== Uses Construction contract............................... $544 Coker project contingency........................... 28 Interest during construction, net of interest income............................................. 89 Start-up, development, asset acquisition and other construction costs................................. 22 Financing costs, legal and other transaction costs.. 32 ---- Total Uses............................................ $715 ==== Interest expense during construction, net of interest income was calculated in the Purvin & Gertz base case model using the expected construction timeline, related funding requirements and interest rates of 12.50% on the outstanding notes and 10.75% construction and term loan facility. 8 Summary of Terms of the Exchange Offer On August 19, 1999, Port Arthur Finance completed the private offering of the outstanding notes.

You will not have any recourse against our other 13 owners and affiliates, including Clark Refining & Marketing, Clark USA, Clark Refining Holdings, Blackstone and Occidental, for any failure by any of us, Sabine River or Neches River to satisfy obligations under the notes. Collateral................ Payment of the outstanding notes and our other senior debt is, and the exchange notes when issued will be, secured by security interests in substantially all of our assets, including those described under the heading "Description of Our Principal Financing Documents--Common Security Agreement--Scope and Nature of the Security Interests." Collateral Sharing........ The collateral is shared equally and ratably with the other senior lenders, any replacement senior lenders and the oil payment insurers in the manner described in "Description of Our Principal Financing Documents--Common Security Agreement" and "--Intercreditor Agreement." Redemption at our Option.. We may choose to redeem some or all of the notes at any time, without the consent of noteholders, at a redemption price equal to: . 100% of the unpaid principal amount of notes being redeemed, plus . accrued and unpaid interest, if any, on the notes being redeemed, up to but excluding the date of redemption, plus . a make-whole premium which is based on the rates of treasury securities with average lives comparable to the average life of the remaining scheduled payments of principal of the notes plus 75 basis points. Mandatory Redemption...... If we receive specified mandatory prepayment proceeds, including specified insurance and other recovery proceeds from casualty events, condemnation compensation and late payments to the extent not needed for payments of interest, and buydown payments from Foster Wheeler USA, we will be required to redeem all our outstanding senior debt, including the notes, on a ratable basis.

The common security 14 agreement also contains restrictions on our ability to make distributions to our owners and to incur additional or replacement senior debt. The terms of the common security agreement are discussed in "Description of Our Principal Financing Documents-- Common Security Agreement." Ownership and Control..... Blackstone does not have the right to dispose of its equity interest in Clark Refining Holdings, except in limited circumstances described under "Description of Our Principal Financing Documents-- Transfer Restrictions Agreement." In addition, Clark Refining Holdings may not dispose of its indirect interest in the Port Arthur refinery, Clark Refining & Marketing or Port Arthur Coker Company, except in limited circumstances following final completion of our coker project as described under "Description of Our Principal Financing Documents--Transfer Restrictions Agreement." 15 RISK FACTORS You should carefully consider the following information, together with the other information in this prospectus, before tendering your outstanding notes. Construction Risks Construction of our coker project and/or the refinery upgrade project could be delayed for reasons beyond our control or beyond our contractors' control. Under a fixed price turnkey construction contract, Foster Wheeler USA has guaranteed final completion of our coker project by December 2001, and under a separate performance guarantee, Foster Wheeler Corporation has guaranteed Foster Wheeler USA's performance under this construction contract. Under a separate contract with Clark Refining & Marketing, Foster Wheeler USA has agreed to complete Clark Refining & Marketing's portion of the refinery upgrade project by that date as well. In addition, Air Products has agreed to complete construction of a hydrogen supply plant at the Port Arthur refinery by December 2000, which is necessary for our heavy oil processing facility. Other than the equity commitments of Blackstone and Occidental in the aggregate amount of approximately $135 million, neither Blackstone nor Occidental is obligated to cause completion or otherwise provide any completion support. The construction and timely completion of our coker project and of the entire refinery upgrade project could be delayed for reasons beyond our control and the control of our contractors, including the following: . shortages of equipment, materials and labor; . work stoppages and other labor disputes; . litigation; . unanticipated increases in costs; . adverse weather conditions and natural disasters; and . accidents. If any of these events or other unanticipated events occur, the construction of our coker project, the refinery upgrade project and/or the hydrogen supply plant may be delayed, our coker project may cost us more to complete than we have currently budgeted, or our coker project may not perform as well as we expect it to, which could cause us to be unable to make payments on the notes and our other debt when due. We cannot guarantee that our coker project has been properly designed or that our coker project will be successfully integrated with the Port Arthur refinery. The successful operation of our coker project is subject to engineering and design uncertainties. We cannot be sure that our coker project will operate as designed or that it will be integrated effectively with the Port Arthur refinery. A delay in the successful integration of our coker project with the Port Arthur refinery would materially affect our ability to generate revenues and make payments on the notes and our other debt when due. The liquidated damages that we may receive from Foster Wheeler USA and Air Products for construction delays or failures to satisfy performance requirements may not be sufficient to compensate us for our resulting losses. Foster Wheeler USA is obligated to pay us liquidated damages in the event of delays in construction or the failure of our coker project to satisfy standards relating to capacity, efficiency and reliability. Similarly, Air 16 Products is obligated to pay us limited liquidated damages in the event the hydrogen supply plant is not completed on time. These liquidated damages are subject to caps and may otherwise not be sufficient to cover the losses that we could incur as a result of construction delays or failures to satisfy performance requirements. As a result, a delay in construction or a failure of our coker project to satisfy performance requirements--notwithstanding that we may be entitled to receive liquidated damages under our construction contract or our hydrogen supply agreement--could cause us to be unable to make payments on the notes and our other debt when due. If construction of our coker project is delayed, P.M.I. Comercio Internacional may be able to terminate our long term crude oil supply agreement, which would cause us to lose the benefit of our coker gross margin support mechanism. Under our long term crude oil supply agreement with P.M.I. Comercio Internacional, we must complete the refinery upgrade project by January 2001 or make specified payments to P.M.I. Comercio Internacional to extend this scheduled completion date. If we must extend this scheduled completion date beyond July 2001, the coker gross margin support mechanism will terminate in July 2009, unless extended by an event beyond our reasonable control that delays completion, like a fire, an earthquake or an act of a governmental authority. Therefore, if the completion of the refinery upgrade project has not occurred for any reason other than an event beyond our reasonable control by July 2001, we will have the benefit of the coker gross margin support mechanism in our long term oil supply agreement for a period shorter than eight years. If we do not make payments to extend this scheduled completion date and it is not extended by an event beyond our reasonable control, P.M.I. Comercio Internacional will have the right to terminate our long term crude oil supply agreement and we would be liable to P.M.I. Comercio Internacional for damages. If this were to occur, we would lose the benefit of the coker gross margin support mechanism contained in our long term crude oil supply agreement, which could impair our ability to make payments on the notes and our other debt when due. Market Risks Our cash flows are subject to fluctuations in the market prices of crude oil, other feedstocks and refined products, which are beyond our control and which may be volatile. Our net operating cash flow will be a function of the cost of heavy sour crude oil which we purchase and the price at which our refined products may be sold. The price we must pay at any time for crude oil and the prices paid to us at any time for our refined products by Clark Refining & Marketing under our product purchase agreement will be based upon prevailing market prices of similar commodities. The markets and prices of these commodities are subject to considerable fluctuation and depend upon many factors beyond our control, such as the following: . the aggregate demand for crude oil and refined products, which are influenced by factors such as the state of the economy and weather patterns; . the prices and availability of imports of refined products and feedstocks; . refining industry utilization rates within the industry; . the prices and availability of alternative products; . the impact of energy conservation efforts; . international political and economic events; . the level of taxation; and . aggregate refinery capacity in the oil refining industry to convert heavy sour crude oil into refined products. Any of these factors could affect the price differential between the price of heavy sour crude oil and refined products. We cannot guarantee that the differential will not decrease below the amount needed for us to generate net cash flow sufficient to make payments on the notes and other debt when due. 17 The coker gross margin support mechanism in our long term crude oil supply agreement with P.M.I. Comercio Internacional may not adequately protect us from fluctuations in the relative prices of heavy sour crude oil and refined products. Our long term crude oil supply agreement with P.M.I. Comercio Internacional includes a coker gross margin support mechanism based on a formula that is intended to be an approximation for coker gross margin and is designed to provide for a minimum average coker gross margin over the first eight years following completion of the refinery upgrade project, assuming we achieve completion by July 2001. However, this mechanism covers our coker gross margins, not margins of all products produced by our heavy oil processing facility. In addition, the formula incorporates variables based on benchmark products that are proxies for actual feedstocks and outputs rather than the feedstocks and outputs themselves. Finally, the relationships among the variables in the formula could change over time, reflecting a change in the market for the products, and the agreement provides for adjustments if these relationships change. We cannot assure you that the coker gross margin support mechanism will adequately protect us against fluctuations in the relative prices of heavy sour crude oil and refined products. The projections and assumptions about our future performance may prove to be inaccurate. We were formed for the purpose of developing, constructing and operating our heavy oil processing facility and have no operating history. Moreover, because our coker project is not yet complete, we have no actual operating results. As a result, the financing of our coker project is based upon assumptions and financial projections regarding our revenues and operating, maintenance and capital costs, including that Clark Refining & Marketing will exercise its right to utilize our excess processing capacity. Purvin & Gertz, in its role as an independent consultant, has reviewed the refinery upgrade project and prepared reports on the technical, environmental and economic aspects of the refinery upgrade project. Purvin & Gertz's "Independent Engineer's Report," dated August 10, 1999, and its "Crude Oil and Refined Product Market Report," dated July 13, 1999 are provided to you as Annexes B and C of this prospectus. In preparing the reports, Purvin & Gertz utilized actual oil prices through June 1999. The reports set forth Purvin & Gertz's projections for our operations and include discussions of the many assumptions utilized by Purvin & Gertz in preparing their projections. Among the many assumptions used by Purvin & Gertz in developing these projections are construction costs, operating expenses, market prices of feedstocks and refined products, repair and maintenance costs, efficiency of operations, the ability of Clark Refining & Marketing to perform its contractual obligations, the market for our refined products if Clark Refining & Marketing defaults in its product purchase obligations, tax payments, inflation and capital costs. These assumptions contain significant uncertainties. Although we and Purvin & Gertz believe that the assumptions made are reasonable, neither we nor Purvin & Gertz nor any other person assumes any responsibility for their accuracy. Therefore, we can make no representation about the likely existence of any particular future set of facts or circumstances. Purvin & Gertz's projections are not necessarily an indication of our future performance. In fact, our actual results will differ, perhaps materially, from those projected. If our actual results are less favorable than those projected, or if the assumptions Purvin & Gertz used in preparing their financial projections prove to be incorrect, we may be unable to make payments on the notes and our other debt when due. 18 Operating Risks We may not be able to operate on a "stand-alone" basis. Our heavy oil processing facility was not designed to operate on a "stand- alone" basis.,In the event of bankruptcy or other material interruption in the operations of Clark Refining & Marketing we may not be able to operate economically because our dependence on Clark Refining & Marketing would limit our ability to obtain feedstock, deliver products and obtain other services and supplies from parties unaffiliated with Clark Refining & Marketing. Thus, we cannot assure you that we would in fact be able to operate on a stand-alone basis without Clark Refining & Marketing. Our operations involve many risks common to other similar industrial facilities, including technology risk, operating risk, availability risk and the risk of events beyond our control. Our operations will involve many risks, such as the following: . breakdown or failure of necessary equipment or processes; . inability to obtain required materials such as Maya and hydrogen; . inability to dispose of hazardous waste products produced by our operations; . the discovery of technological design defects; and . the occurrence of events beyond our control, such as fires, explosions, earthquakes, floods and changes in law and eminent domain proceedings. The occurrence of the kinds of events listed above could significantly decrease our revenues and/or significantly increase our costs and therefore impair our ability to make payments on the notes and our other debt when due. Our insurance coverage may not be adequate. We will maintain customary insurance for our operations, including builder's risk, commercial general liability, business interruption insurance and contingent business interruption insurance. However, not all operating risks are insurable and the insurance proceeds applicable to covered risks may not be adequate to cover lost revenues, increased expenses or other costs related to these occurrences. In addition, the insurance that we currently have may not be available in the future at commercially reasonable rates. Our operations are subject to substantial permitting and regulatory requirements, and our failure to comply with these requirements could subject us to material liability. Like many operations in the oil and gas industry, our coker project is required to obtain and maintain a number of permits and to comply with constantly changing provisions in numerous statutes and regulations relating to, among other things, construction, improvements, business operations, the safety and health of employees and the public, employment, hiring and anti- discrimination. These requirements may impose significant additional costs on us, and may even result in civil or criminal liability. There can be no assurance that we and our contractors and suppliers will at all times be in compliance with all applicable statutes and regulations or have all necessary permits in place, nor can we assure you that we will be able to operate our coker project in accordance with all our permits and approvals. Furthermore, because of the integration of our coker project with the operations of the Port Arthur refinery, failure by Clark Refining & Marketing to obtain and maintain all necessary permits or to be in compliance at all times with applicable regulations also could affect our financial condition or results of operations. Any of these circumstances could impair our ability to make payments on the notes and our other debt when due. 19 Risks Associated with our Reliance on Clark Refining & Marketing We are relying on Clark Refining & Marketing as our sole source of revenue for the sale of our refined products. We have entered into a product purchase agreement with Clark Refining & Marketing that obligates Clark Refining & Marketing to purchase all of our refined products tendered for delivery. We have not entered into any arrangements with any other party for the sale of our refined products. Thus, our source of revenue for the sale of our refined products will be payments by Clark Refining & Marketing under our product purchase agreement and, if Clark Refining & Marketing exercises its right of first refusal, processing fees from Clark Refining & Marketing under our services and supply agreement. You should note that under our product purchase agreement, Clark Refining & Marketing may suspend its obligations to purchase our output if specified events beyond the control of Clark Refining & Marketing occur, such as interruptions in the delivery of crude oil to the Port Arthur refinery, adverse weather conditions, labor disputes or changes in law. Furthermore, under specified circumstances, Clark Refining & Marketing may terminate our product purchase agreement if we fail to deliver the refined products substantially in accordance with the terms of the agreement. If any of these events occur, or if Clark Refining & Marketing should default on its purchase obligations, we cannot assure you that a third-party market will be available for our refined products or that our operating margins will be sufficient to enable us to make payments on the notes and our other debt when due. We are relying on Clark Refining & Marketing to manage our operations. We have entered into a services and supply agreement with Clark Refining & Marketing that obligates Clark Refining & Marketing to manage our heavy oil processing facility. In the event Clark Refining & Marketing fails to perform its obligations under the services and supply agreement, we would need to hire additional employees and/or enter into other arrangements to provide for services and supplies previously provided by Clark Refining & Marketing. We cannot give you any assurance that such employees and services will be readily available and will have the skills and capacity necessary to operate our heavy oil processing facility, or, if they are available, that they will be available on terms as favorable as those of our services and supply agreement with Clark Refining & Marketing. Thus, if Clark Refining & Marketing breaches its obligations to us, or terminates our services and supply agreement, our operating expenses could increase materially and we could be unable to make payments on the notes and our other debt when due. We may have conflicts of interest under our various arrangements with Clark Refining & Marketing. We have numerous contracts and relationships with Clark Refining & Marketing, including our services and supply agreement, our product purchase agreement and various leases. In negotiating these contracts, we and Clark Refining & Marketing intended to provide terms that are substantially similar to those that might have been obtained from unaffiliated third parties. However, we cannot assure you that any of these arrangements actually meet that standard. Furthermore, in carrying out its obligations under our services and supply, product purchase and other contracts, including its obligations to resolve disputes under those contracts, Clark Refining & Marketing may face conflicts of interest in making decisions that affect us. Although Clark Refining & Marketing has agreed to carry out its obligations to us in a manner that is nondiscriminatory to us, as a practical matter our ability to monitor compliance by Clark Refining & Marketing is limited. As a result, we cannot guarantee that Clark Refining & Marketing will carry out its obligations to us in a manner that is nondiscriminatory to us. The bankruptcy of Clark Refining & Marketing could cause our assets and liabilities to be consolidated with those of Clark Refining & Marketing and could prevent us from making payment on the notes. We have taken steps to maintain the legal existence of Port Arthur Coker Company, Port Arthur Finance, Sabine River and Neches River independent from that of Clark Refining & Marketing, Clark USA and Clark Refining Holdings. However, in a bankruptcy filing by Clark Refining & Marketing, Clark Refining Holdings or Clark USA, a court could, under the doctrine of substantive consolidation, disregard our separate existence and order the consolidation of our assets and liabilities with those of Clark Refining & Marketing, Clark 20 Refining Holdings and Clark USA. If a court were to reach this conclusion, we could be prevented from paying amounts due on the notes and our other debt when due and the court could order that the collateral securing our senior debt, including the notes, be shared with debt holders of Clark Refining & Marketing. Furthermore, a court could set aside payments previously made by us to noteholders by finding that the distributions were preferential payments made in violation of bankruptcy laws. Finally, even if a court were to decide ultimately that our assets should not be consolidated with those of Clark Refining & Marketing, Clark Refining Holdings and Clark USA, during the pendency of the bankruptcy proceeding, we might be prevented from making payments on the notes and our other debt when due. Risks Associated with our Relationship with P.M.I. Comercio Internacional We are highly dependent upon P.M.I. Comercio Internacional and PEMEX for our supply of heavy sour crude oil. Our long term crude oil supply agreement with P.M.I. Comercio Internacional obligates it to supply all heavy sour crude oil needed by us. P.M.I. Comercio Internacional indirectly obtains its supply of heavy sour crude oil under a separate supply arrangement with Pemex Exploracion y Produccion. Therefore, P.M.I. Comercio Internacional's ability to deliver heavy sour crude oil is influenced by the adequacy of Pemex Exploracion's crude oil reserves, the estimates of which are not precise and are subject to revision at any time. We have not entered into any other arrangements to supply us with heavy sour crude oil. In the event P.M.I. Comercio Internacional were to terminate our long term crude oil supply agreement or default on its supply obligations, we would lose the benefits of our coker gross margin support mechanism and would need to obtain heavy sour crude oil from another supplier. If either of these events were to occur, we cannot guarantee you that an alternative supply of crude oil would be available. Furthermore, even if we were able to obtain an alternative supply of heavy sour crude oil, that supply may not be on terms as favorable as those negotiated with P.M.I. Comercio Internacional. In addition, the processing of oil supplied by a third party may require changes to our heavy oil processing facility, which could require significant unbudgeted capital expenditures. As a result, our ability to make payments on the notes and our other debt when due may be impaired. Our supply of heavy sour crude oil from P.M.I. Comercio Internacional could be interrupted by events beyond its control. P.M.I. Comercio Internacional's obligation to deliver heavy sour crude oil under our long term crude oil supply agreement may be delayed or excused by the occurrence of conditions and events beyond the reasonable control of P.M.I. Comercio Internacional, such as the following: . weather-related conditions; . production or operational difficulties and blockades; . embargoes or interruptions, declines or shortages of P.M.I. Comercio Internacional's supply of Maya available for export from Mexico, including shortages due to increased domestic demand and other national or international political events; and . laws, changes in laws, decrees, directives or actions, other than those that are not common to other similar long term crude oil supply agreements, of the government of Mexico. The occurrence of any of these or similar events beyond its reasonable control could excuse P.M.I. Comercio Internacional from delivering heavy sour crude oil, and could therefore require us to obtain heavy sour crude oil from another source. If this were to occur, our ability to make payments on the notes and our other debt when due could be impaired. 21 The government of Mexico may direct a reduction in our supply of crude oil so long as that action is taken in common with proportionately equal supply reductions under other long term crude oil supply agreements and the amount by which it reduces the quantity of Maya to be sold to us shall first be applied to reduce quantities of Maya scheduled for sale and delivery to the Port Arthur refinery under any other crude oil supply agreement with us or any of our affiliates. Mexico is not a member of the Organization of Petroleum Exporting Countries, but in 1998 it agreed with the governments of Saudi Arabia and Venezuela to reduce Mexico's exports of crude oil by 200,000 barrels per day. In March 1999, Mexico further agreed to cut exports of crude oil by an additional 125,000 barrels per day. As a consequence, during 1999, PEMEX reduced its supply of oil under some oil supply contracts by invoking an excuse clause based on governmental action similar to one contained in our long term crude oil supply agreement. We cannot guarantee that PEMEX will not reduce our supply of crude oil by similarly invoking the excuse provisions for events beyond P.M.I. Comercio Internacional's reasonable control agreement in the future. We may not be able to enforce civil liabilities against P.M.I. Comercio Internacional. P.M.I. Comercio Internacional is organized under the laws of the United Mexican States. PEMEX, P.M.I. Comercio Internacional's parent and guarantor of P.M.I. Comercio Internacional's obligations under our long-term crude oil supply agreement, is a public entity of the United Mexican States. All or a substantial portion of the assets of PEMEX and P.M.I. Comercio Internacional and their respective directors and officers are located outside the United States. As a result, investors may not be able to serve process within the United States upon P.M.I. Comercio Internacional, PEMEX or their respective directors or officers, or to enforce against them, in United States courts, any judgment based solely upon civil liability provisions of the laws of jurisdictions other than the United Mexican States. Furthermore, in some cases, private parties cannot sue governmental authorities because the governmental authority claims the benefit of what is known as "sovereign immunity." P.M.I. Comercio Internacional has agreed in our long term crude oil supply agreement, and PEMEX has agreed in our long term crude oil supply agreement guarantee, not to claim, and has waived, any immunity from suit or other legal process, subject to some limitations. There can be no assurance, however, that either P.M.I. Comercio Internacional and/or PEMEX will actually continue to do so in the future. Environmental Risks The Port Arthur refinery is located on a contaminated site. If the previous owners and operators do not fulfill their remediation obligations, we may incur substantial remediation costs. Environmental laws typically provide that the owners or operators, including lessees, of contaminated properties may be held liable for their remediation. Such liability is typically joint and several, which means that any responsible party can be held liable for all remedial costs, and can be imposed regardless of whether the owner or operator caused the contamination. The Port Arthur refinery is located on a contaminated site. Under the 1994 purchase agreement between Clark Refining & Marketing and Chevron Products USA relating to the Port Arthur refinery, Chevron retained environmental remediation obligations regarding pre-closing contamination at over 97% of the refinery site. Clark Refining & Marketing assumed responsibility for any remediation that is required in and under the remaining approximately 3% of the refinery site, which consists of specified areas that extend 25 to 100 feet from active operating units, including soil and groundwater, and, Clark Refining & Marketing has estimated its liability for remediation of groundwater and soil in these areas at $27 million. Chevron is obligated to remediate the contamination in the areas for which it has retained responsibility as and when required by law, in accordance with remediation plans negotiated by Chevron and the applicable federal or state agencies. 22 No part of our coker project site is located within the portion of the Port Arthur refinery site for which Chevron retains environmental remediation obligations. We have estimated remedial costs relating to our coker project site, which encompasses less than 50 acres of the total Port Arthur refinery site surface area, at $1.6 million. Clark Refining & Marketing has agreed to retain liability regarding contamination existing at the coker project site and has indemnified us against such liabilities. However, if Clark Refining & Marketing does not fulfill its remediation obligations, we could incur substantial additional costs in remediating the contamination, which could impair our ability to make payments on the notes and our other debt when due. Our failure to comply with existing and future environmental laws and regulations could subject us to material liabilities or other sanctions. Our operations are subject to numerous federal, state and local environmental laws and regulations, such as those governing discharges to air and water, the handling and disposal of solid and hazardous wastes and the remediation of contamination. Although Clark Refining & Marketing has agreed in our services and supply agreement to manage our heavy oil processing facility and to comply at our cost with all applicable environmental laws and regulations, we cannot guarantee you that this will always be the case. Any failure to comply with these environmental requirements could subject us to, among other things, civil liabilities, criminal penalties and the temporary or permanent shutdown of our operations. We cannot predict with certainty the future costs of environmental compliance because of frequently changing compliance standards and technology. We expect that future regulations or changes in existing environmental laws and regulations or other interpretation may subject our operations to increasingly stringent standards. Compliance with these requirements may make it necessary, at costs that may be substantial, for us to undertake new measures in connection with the storage, handling, transport, treatment or disposal of hazardous materials, petroleum by-products and wastes and the remediation of contamination. The costs of such actions could impair our financial condition, results of operations or cash flows and accordingly could impair our ability to make payments on the notes and our other debt when due. Financing Risks Our equity and debt funding sources may be inadequate and are subject to extensive conditions precedent that may not be satisfied and may cause us to be unable to pay our construction costs and our debt service obligations. We expect initial funding commitments to be sufficient to pay amounts owing to our contractors for the construction of our coker project and to fund all other costs associated with developing, financing, constructing and commissioning our coker project, including an allowance for contingencies. However, we cannot assure you that no circumstances will arise that will require additional funding beyond that for which we have obtained commitments. You should also note that the equity commitments of our sponsors are limited to approximately $122 million for Blackstone and approximately $13 million for Occidental, and there is no other recourse to Blackstone or Occidental either prior to or after completion of our coker project. In addition, drawdowns under many of our funding commitments are subject to extensive conditions precedent, including the absence of any material adverse changes. We cannot guarantee that all the applicable conditions precedent for drawdowns under each of our funding commitments will be satisfied at all times during or after the construction period. Therefore, we may be unable to draw down these funds, which could cause us to be unable to meet our payment obligations to our contractors and/or our debt service obligations. If we default on the notes after completion, your recourse will be limited to the assets and cash flows of our coker project. After completion of our coker project, our assets and cash flows from our operations will be our sole source for repayment of the notes and our other debt. Except for Sabine River and Neches River, no other owner or other affiliate of us, including Clark Refining & Marketing, will be responsible for making payments on the notes or will guarantee in any way the payment of the notes. In the event that we default in our payment 23 of amounts due on the notes, we cannot guarantee to you that the proceeds realized upon a foreclosure and sale of our coker project will be sufficient to pay amounts then outstanding on the notes. Thus, our ability to make payments on the notes and our other debt when due will be entirely dependent upon our ability to construct our coker project successfully and to operate in a manner that provides sufficient cash flow to make payment on the notes and our other debt when due. The collateral securing the notes may be insufficient to pay amounts due on the notes in the event of a foreclosure. The outstanding notes are, and when issued the exchange notes will be, secured by substantially all our assets and rights and other assets and rights of other parties. You should note, however, that while the guarantee agreement by which PEMEX has guaranteed the obligations of P.M.I. Comercio Internacional under our long term crude oil supply agreement is part of the collateral, the supply agreement between P.M.I. Comercio Internacional and Pemex Exploracion is not part of the collateral securing the notes and other senior debt. In addition, there may be limitations on our ability to create security interests in some assets and rights or to legally protect your interest in some of the collateral from claims by third parties. This is particularly true with respect to security interests in governmental permits or technology licenses. We cannot assure you that if we default on the notes and you foreclose on and sell our assets you will receive proceeds to pay all amounts that we owe you on the notes. Furthermore, your ability to foreclose on the collateral will be subject to practical problems associated with the realization of the security interests such as obtaining the requisite secured party consent to foreclose on the collateral. We cannot assure you that your collateral trustee will be able to realize upon the collateral without difficulty or delay or that procedures implemented to support the validity and enforceability of security interests will be sufficient. We cannot assure you that if you try to foreclose on our assets, you will receive all the third-party approvals that you need. The collateral securing the notes is shared with our other senior secured lenders, and this may cause the collateral to be an insufficient source from which to pay amounts due on the notes. We have substantial other senior secured indebtedness that ranks equally and ratably with the notes and is entitled to the benefits of a common security package. Our other senior secured indebtedness includes the following: . a construction and term loan facility of $325 million; . working capital facilities of up to $75 million; and . reimbursement obligations of up to $150 million, resulting from payments under the guaranty insurance policy relating to our payment obligations under our long term crude oil supply agreement. The collateral provided for your benefit will be shared, on an equal and ratable basis, with the other senior secured parties. You will share control over enforcement of the common security package with all the other senior lenders. In specified circumstances, the direction of a specified percentage of all of the senior lenders, including you, will be required to initiate foreclosure and you should not expect that the noteholders in those circumstances will themselves constitute the required percentage for control of that action. For a substantial period during which the notes will be outstanding, amounts due to other senior secured parties will also remain outstanding and be secured by the same collateral and our total outstanding senior secured indebtedness could be as much as $805 million. We cannot assure you that, upon the occurrence of an event of default and acceleration, the exercise of remedies, including foreclosing on the collateral, would provide funds sufficient to pay all or even a substantial portion of the outstanding principal and accrued interest on the notes as well as all amounts due to the other secured parties. Events of default include failure to pay interest, principal or fees when due, the falsity of representations and warranties that we made in connection with the financing, breach of any of our covenants, which include covenants relating to timely completion of 24 our coker project, preservation of our existence, and not amending our project documents, mis-application of funds, cross-defaults to our other financing documents and to the long term oil supply agreement, the hydrogen supply contract and our other project documents, insolvency of ourselves, Sabine River, Neches River or, prior to completion of our coker project, Blackstone, and failure of Clark Refining & Marketing or Air Products to complete their portions of the refinery upgrade project. We may incur additional debt, which may reduce the benefits of the collateral. Subject to the limitations set forth in the common security agreement, we are permitted to incur additional indebtedness. This additional indebtedness may rank equally with the notes and share ratably in the collateral that secures the notes and thus may increase the risk that we will be unable to make payments on the notes and our other debt when due. This may reduce the benefits of the collateral to you and your ability to control all actions taken with respect to the collateral. There is no existing market for the exchange notes, and we cannot assure you that an active trading market will develop for the exchange notes or that you will be able to sell your exchange notes. There is no existing market for the exchange notes, and there can be no assurance as to the liquidity of any markets that may develop for the exchange notes, your ability to sell your exchange notes or the prices at which you would be able to sell your exchange notes. Future trading prices of the exchange notes will depend on many factors, including, among other things, prevailing interest rates, our operating results and the market for similar securities. The initial purchasers of the outstanding notes are not obligated to make a market in the exchange notes and any market making by them may be discontinued at any time without notice. We do not intend to apply for a listing of the exchange notes on any securities exchange or on any automated dealer quotation system. Historically, the market for non-investment grade debt has been subject to disruptions that have caused volatility in prices. It is possible that the market for the exchange notes will be subject to disruptions. Any such disruptions may have a negative effect on you, as a holder of the exchange notes, regardless of our prospects and financial performance. If you choose not to exchange your outstanding notes, the present transfer restrictions will remain in force and the market price of your outstanding notes could decline. If you do not exchange your outstanding notes for exchange notes under the exchange offer, then you will continue to be subject to the transfer restrictions on the outstanding notes as set forth in the prospectus distributed in connection with the offering of the outstanding notes. In general, the outstanding notes may not be offered or sold unless they are registered or exempt from registration under the Securities Act and applicable state securities laws. Except as required by the registration rights agreement, we do not intend to register resales of the outstanding notes under the Securities Act. You should refer to "Prospectus Summary --Summary of the Exchange Offer" and "The Exchange Offer" for information about how to tender your outstanding notes. The tender of outstanding notes under the exchange offer will reduce the principal amount of the outstanding notes outstanding, which may have an adverse effect upon, and increase the volatility of, the market price of the outstanding notes due to a reduction in liquidity. 25 USE OF PROCEEDS Port Arthur Finance will not receive any cash proceeds from the issuance of the exchange notes. In consideration for issuing the exchange notes as contemplated in this prospectus, Port Arthur Finance will receive in exchange a like principal amount of outstanding notes, the terms of which are identical in all material respects to the exchange notes. The outstanding notes surrendered in exchange for the exchange notes will be retired and canceled and cannot be reissued. Accordingly, issuance of the exchange notes will not result in any change in the capitalization of Port Arthur Finance. See "Financing Plan" for a discussion of the use of proceeds from the sale of the outstanding notes. 26 FINANCING PLAN We estimate that the total costs for our coker project will be approximately $715 million. Our sources of funds are described as follows. Equity Contributions and Commitments Blackstone and Occidental have agreed to make capital contributions in an aggregate maximum amount of approximately $135 million under capital contribution agreements. The lenders of our senior debt have the right to enforce the obligations of Blackstone and Occidental to make capital contributions under these agreements. Under these capital contribution agreements, when we issued the outstanding notes Blackstone and Occidental made initial equity contributions in the aggregate amount of $20 million which flowed down through our ownership structure to us and have made approximately $41 million in additional equity contributions since such time, bringing the total to approximately $61 million as of February 29, 2000. During the remaining construction period, Blackstone will make additional periodic equity contributions of approximately $66 million and Occidental will make approximately $8 million in additional equity contributions. These additional equity contributions will be made on a ratable basis with drawings under the secured construction and term loan facility described below to pay for construction costs and will flow down through our ownership structure to us. Under these capital contribution agreements, if Blackstone or Occidental is excused by operation of law in a bankruptcy proceeding of us, either Sabine River, Neches River or Clark Refining Holdings or, for any other reason, Blackstone and Occidental, will be required either to make subordinated loans to us or to purchase subordinate participations in the senior debt, in either case in the amounts of their individual capital contribution commitments. Outstanding Notes and Existing Bank Credit Facilities Approximately $580 million of the budgeted cost of developing, financing and constructing our coker project is being funded with senior debt. Our senior debt consists of $255 million from the sale of the outstanding notes and $325 million from borrowings under the bank credit facilities described below. When we issued the outstanding notes, we also entered into a construction and term loan agreement with a syndicate of lenders establishing a secured construction and term loan facility. The construction and term loan facility is split into a Tranche A of $225 million and a Tranche B of $100 million, with Tranche A loans having a term of 7.5 years and Tranche B loans having a term of 8 years. Under specified circumstances, the aggregate amount of the construction and term loan facility may be reallocated between the tranches with our consent, which may not be unreasonably withheld. In November 1999, the lenders under our construction and term loan facility requested that we reallocate $5 million from Tranche A to Tranche B. At the time our construction and term loan facility closed, the bank arrangers intended to reduce their commitment exposure to us by syndicating their commitments with other banks. We agreed that if necessary in order to complete the syndication of the construction and term loan facility, the bank arrangers with our consent, which may not be unreasonably withheld, may increase the interest rate margins on the construction and term loan facility upon a reaffirmation from Moody's and Standard & Poor's of our then-current rating after giving effect to such increase. We also obtained a secured working capital facility of up to $75 million with a term of up to 7.5 years at the time the outstanding notes were issued. Any portion of the secured working capital facility that is advanced as loans will bear interest at an annual rate of LIBOR plus 4.75% or at a prime rate plus 3.75%, at our election. We are required to pay fees on any letters of credit issued under the secured working capital facility equal to an annual rate of LIBOR plus 4.75%, plus an annual facing fee of 0.15%. We also pay commitment fees on the unutilized portion of the construction and term loan facility equal to 0.75% per annum and on the unutilized portion of the secured working capital facility equal to 0.50% per annum. In February 2000, our $75 million secured working capital facility was reduced to $35 million. The $40 million reduction, a portion of which had been outstanding in the form of a letter of credit to P.M.I. Comercio Internacional to secure against a default by us under our long term oil supply agreement, was replaced by an insurance policy under which an affiliate of American International Group agreed to insure P.M.I. Comercio Internacional against our default under the 27 long term oil supply agreement up to a maximum liability of $40 million. This affiliate of American International Group is treated as a bank senior lender under the common security agreement. Port Arthur Finance transferred the net proceeds of the offering of the outstanding notes to Port Arthur Coker Company by means of an intercompany note and will transfer the proceeds of drawings under the bank credit facilities to Port Arthur Coker Company by means of the intercompany note. Port Arthur Coker Company has, or will, use such proceeds principally to pay part of the costs of our coker project and related items, including: . amounts payable under our construction contract; . other asset acquisition costs; . initial start-up costs and working capital requirements; . financing costs, legal and other transaction costs, taxes and interest during construction; . other costs and expenses associated with our coker project; and . establishment of a construction contingency fund. The net proceeds from the sale of the outstanding notes, after deducting discounts offered to the initial purchasers and related transaction expenses payable, was approximately $244 million. Winterthur Insurance Policies Winterthur, on behalf of a group of insurers, arranged a $150 million oil payment guaranty insurance policy to provide payment security for crude oil purchases by us from P.M.I. Comercio Internacional. In order to accommodate a financing structure that includes the bank credit facilities, the Winterthur oil payment guaranty insurance policy and the notes, we have entered into a common security agreement which contains, among other things, common covenants, representations and warranties, events of default and remedies applicable to all our senior debt and reimbursement obligations to Winterthur relating to its oil payment guaranty insurance policy, including the notes and any loans made under our bank credit facilities. The terms of the common security agreement are discussed under the heading "Description of Our Principal Financing Documents--Common Security Agreement" in this prospectus. 28 The following table sets forth the estimated sources and uses of funds in connection with the development, construction and financing of our coker project through completion and commercial operation of our heavy oil processing facility, including the notes. We cannot assure you that these estimates will correspond to the actual uses of funds to complete our coker project. Proceeds from the sale of the outstanding notes were deposited into an account called the bond proceeds account and must be applied in accordance with the financing documents. As required under our construction and term loan facility, the entire amount of Tranche B loans were drawndown in October 1999 and $35.4 million of additional equity was contributed by Blackstone and Occidental. These amounts were deposited into an account called the bank loan drawdown and equity funding account and will be applied in accordance with the financing documents. You should read the section captioned "Description of Our Principal Financing Documents--Common Security Agreement--Account Structure" in this prospectus for more information regarding the accounts we are required to maintain and fund and regarding restrictions on our ability to use funds from these accounts.

Interest expense during construction, net of interest income was calculated in the Purvin & Gertz base case model using the expected construction timeline, related funding requirements and interest rates of 12.50% on the outstanding notes and 10.75% construction and term loan facility. We believe that the proceeds of the sale of the outstanding notes, equity contributions and monies borrowed under our construction and term loan facility will provide sufficient funds to develop, construct and finance our coker project. 29 CAPITALIZATION The following table sets forth the capitalization of Port Arthur Coker Company as of December 31, 1999, and as adjusted to give effect to the issuance and sale of the outstanding notes and the initial equity contributions, and the application of the estimated proceeds from these sources as described under "Use of Proceeds."

General We were formed to construct, own or lease, operate and maintain our heavy oil processing facility. Since our inception, we have been in the pre-operation stage and have had no material operating revenues or expenses. The total cost to us of our coker project, including development, property acquisitions, construction, capitalized interest, testing and start-up, is estimated to be approximately $715 million, including allowance for estimated price escalation and contingencies. Our notes are unconditionally guaranteed jointly and severally by Port Arthur Coker Company, Sabine River and Neches River. Sabine River and Neches River, however, have no material assets, no liabilities and no operations other than their investment in Port Arthur Coker Company. Operations to Date Clark Refining & Marketing formally initiated the refinery upgrade project in April 1998 after entering into the long term crude oil supply agreement with P.M.I. Comercio Internacional in March 1998. Construction began in September 1998. When we issued the outstanding notes, Clark Refining & Marketing assigned to us all its rights and obligations under the long term crude oil supply agreement, including the obligation to complete the refinery upgrade project, and permits related to operating our new and leased units and we purchased the work in progress relating to our coker project for a total of approximately $159 million. The work on our coker project is well advanced. As of January 2000, 100% of major equipment procurement, 89% of total materials procurement and 98% of detailed design and engineering were complete and construction was 31% complete. Construction activities to date have included site preparation, foundations and footings installation, major equipment installation and pipe rack construction. In June 1999, the six coke drums for our new delayed coking unit arrived at the Port Arthur refinery and in October 1999 were installed in their support structures. In January 2000, approximately 175 people were working on design and engineering and approximately 965 people are working on construction of our coker project. All personnel except one are employees of Foster Wheeler USA, its subcontractors or Clark Refining & Marketing, the latter working under our services and supply agreement with Clark Refining & Marketing. Under our construction contract, Foster Wheeler USA is obligated to perform the engineering, design, procurement, manufacture, construction, erection, installation and testing of our coker project. Under the construction contract, we are required to pay Foster Wheeler USA the fixed sum of approximately $544 million in installments to be based on their progress in completing our coker project. This payment to Foster Wheeler USA has been reduced by $157.1 million, the amount Clark Refining & Marketing had already paid Foster Wheeler USA for work performed to date on our coker project. When we issued the outstanding notes, we used a portion of the proceeds of our senior debt and equity contributions to make the following payments to Clark Refining & Marketing: Payment for work in progress related to our coker project--con- struction contract............................................... $157,100,000 Payment for permits and the long term crude oil supply agreement.. 2,175,000 ------------ Total........................................................... $159,275,000 ============ Plan of Operation The refinery upgrade project will allow our heavy oil processing facility to process an average of 200,000 barrels per stream day of crude oil. At least 150,000 barrels per stream day of heavy sour crude oil will be purchased from P.M.I. Comercio Internacional under our long term crude oil supply agreement. Construction of our coker project and the entire refinery upgrade project is expected to be mechanically complete around November 2000, and we expect to begin commercial operation around January 2001. 33 Our long term crude oil supply agreement includes a mechanism designed to minimize the effect of adverse refining cycles and to moderate the fluctuations of our coker gross margin. This mechanism contains a formula that is intended to be an approximation for coker gross margin and is designed to provide for a minimum average coker gross margin over the first eight years following completion of the refinery upgrade project, if it is completed by July 2001. This eight year period will be shortened by any period of delay in completion of the refinery upgrade project beyond July 2001 unless the delay is caused by events beyond our reasonable control. Clark Refining & Marketing has agreed to provide us with services necessary to complete our coker project and to operate the heavy oil processing facility. Under our services and supply agreement, the services to be performed by Clark Refining & Marketing include, among others, the following: . oversight of the construction of our new units and other equipment and performance of our obligations under our construction contract with Foster Wheeler USA, other than our payment obligations; . operation and maintenance of the ancillary units and equipment that we are leasing from Clark Refining & Marketing; . management of the operation and maintenance of our new processing units and other equipment at the Port Arthur refinery; . management of our crude oil purchases and transportation of our crude oil to the Port Arthur refinery; and . supply of other required feedstocks, materials and utilities. However, Sabine River's board of directors controls the ultimate decision making, and guides the ongoing activities, of Port Arthur Coker Company. In addition, under our services and supply agreement Clark Refining & Marketing has a right of first refusal to require us to process crude oil for them in an amount equal to approximately 20% of the processing capacity of our heavy oil processing facility. In exchange, we will receive processing fees from Clark Refining & Marketing. We have entered into a product purchase agreement with Clark Refining & Marketing for the sale of all refined and intermediate products produced by our heavy oil processing facility. Under our product purchase agreement, Clark Refining & Marketing is obligated to accept and pay for all our products and has a limited right to request that we produce a specified mix of products. Purvin & Gertz expects us to generate approximately $228 million of annual average operating cash flows over the initial 11-year operating period of our coker project. Liquidity and Capital Resources Prior to the completion and commercial operation of our heavy oil processing facility, we expect that the cash available to us will consist principally of equity contributions of up to $135 million, proceeds from the offering of the outstanding notes of $255 million and up to $325 million in proceeds from borrowings under our bank credit facilities, together with interest earnings on those amounts. The contractual arrangements with Blackstone and Occidental provide that the aggregate $135 million equity commitment will be funded pro rata with the funding of our notes and bank term debt, so that at the time of each advance of debt and equity to pay our construction costs, the amount funded will be approximately 65% debt and 35% equity. As of December 31, 1999, $57 million of the $135 million of equity had been funded. We expect the remaining $78 million of equity to be funded by March 2001. We believe that these amounts are sufficient to fund the development, construction and financing costs of our coker project. During the operating period, our revenues will include revenues from sales of products to Clark Refining & Marketing under the product purchase agreement and processing fees paid by Clark Refining & Marketing under the services and supply agreement. We have a working capital facility of up to $35 million from a 34 syndicate of lenders, some of which are the same commercial banks that are providing the construction and term loan facility. The proceeds of any borrowing under this working capital facility will be used primarily for issuing letters of credit for purchase of crude oil other than Maya and to meet our other working capital needs. In February 2000, our working capital facility was reduced from $75 million to $35 million. The $40 million reduction, a portion of which had been outstanding in the form of a letter of credit to P.M.I. Comercio Internacional to secure against a default by us under our long term oil supply agreement, was replaced by an insurance policy under which an affiliate of American International Group agreed to insure P.M.I. Comercio Internacional against our default under the long term oil supply agreement up to a maximum liability of $40 million. In order to fulfill our obligation to provide security to P.M.I. Comercio Internacional for our obligation to pay for shipments of Maya under the long term crude oil supply agreement, we obtained from Winterthur an oil payment guaranty insurance policy for the benefit of P.M.I. Comercio Internacional. This oil payment guaranty insurance policy is in the amount of up to $150 million and will be a source of payment to P.M.I. Comercio Internacional if we failed to pay P.M.I. Comercio Internacional for one or more shipments of Maya. Under our senior debt documents, any payments by Winterthur on this policy are required to be reimbursed by us. This reimbursement obligation to Winterthur has a priority claim on all of the collateral for the senior debt equal to the noteholders and holders of our other senior debt, except in specified circumstances in which it has a senior claim to these parties. We describe these priorities in greater detail in our description of the Intercreditor Agreement under "Description of Our Principal Financing Documents--Guaranty Insurance Policy and Reimbursement Agreement." Under our senior debt documents, we are also required to establish a debt service reserve account at the time our coker project achieves substantial reliability in an amount equal to the next semiannual payment of principal and interest coming due from time to time. Substantial reliability is a term in our construction contract and our financing documents that is used to indicate when Foster Wheeler USA has demonstrated that our coker project is sufficiently complete and can reliably generate expected operating margins. A more detailed description of substantial reliability can be found under the heading "Principal Project Documents--Construction Contract--Performance Testing and Guarantees" in this prospectus. In lieu of depositing funds into this reserve account at substantial reliability, we have arranged for Winterthur to provide a separate debt service reserve insurance policy in the maximum amount of $60 million for a period of approximately five years from substantial reliability of our coker project. Payments will be made under this policy to pay debt service to the extent that we do not have sufficient funds available to make a debt service payment on any scheduled semiannual payment date during the term of the policy. The term of the policy commences at substantial reliability of our coker project and ends on the tenth semiannual payment date after substantial reliability, unless it terminates early because our debt service reserve account is funded to the required amount. The maximum liability of Winterthur under its policy is reduced as we make deposits into the debt service reserve account. On the sixth semiannual payment date after substantial reliability, and on each of the next four semiannual payment dates, we are required to deposit, out of available funds for that purpose, $12 million into the debt service reserve account. In addition, until the debt service reserve account contains the required amount, we are required to make deposits into the debt service reserve account equal to all of our excess cash flow that remains after we apply 75% of excess cash flow to prepay senior debt. Once the debt service reserve account contains the required amount, the Winterthur policy will terminate. When we issued the outstanding notes, we obtained business interruption and contingent business interruption insurance for our heavy oil processing facility. We may also incur additional senior debt or subordinated debt provided that it complies with the terms and conditions set forth in the common security agreement. Accounts The common security agreement requires that all of our bank accounts, with the exception of an unsecured account for up to 30 days' operating costs, be secured for the benefit of our senior lenders, including you. We 35 are required to maintain separate accounts for specified purposes. Deposits and withdrawals from these accounts may only be made in accordance with the terms of our financing documents that specify the order in which our revenues are applied and the order in which our expenses are paid. We describe these accounts, and the maximum amounts required to be deposited in them, in greater detail under "Description of Our Principal Financing Documents--Common Security Agreement--Account Structure." Quantitative and Qualitative Disclosures About Market Risk From time to time, we expect to hold market risk sensitive instruments and positions, such as our inventory of crude oil and refined products. The market risk inherent in our market risk sensitive instruments and positions is the potential loss from adverse changes in commodity prices and interest rates. None of our market risk sensitive instruments are held for speculative trading. Commodity Risk Our feedstocks and refined products are principally commodities and the pricing of such feedstocks and refined products under our services and supply agreement and product purchase agreement is intended to reflect market-based pricing. As a result, our operating cash flows and earnings will be significantly affected by a variety of factors beyond our control, including the supply of, and demand for, crude oil, gasoline and other refined products which, in turn, depend on, among other factors, changes in domestic and foreign economic conditions, weather patterns, political affairs, crude oil production levels, the rate of industry investments, the availability of imports, the marketing of competitive fuels and the extent of government regulations. Purvin & Gertz, the independent engineer, has set forth in its Independent Engineer's Report annexed to this prospectus as Annex B, an analysis of the impact of the changes in prices of crude oil and refined products on our operating cash flow. We believe that their analysis has been made on a reasonable basis. We expect to utilize limited risk management tools to mitigate risk associated with fluctuations in petroleum prices on our normal operating petroleum inventories. We believe this policy is appropriate since inventories are required to operate the business and are intended to be owned for an extended period of time. We believe the cost of using such tools to manage short-term fluctuations outweigh the benefits. In addition, the common security agreement limits our ability to use those tools. We may occasionally use strategies to minimize the impact on profitability of volatility in feedstock costs and refined product prices. These strategies will generally involve the purchase and sale of exchange-traded, energy-related futures and options with a duration of six months or less. In addition, we, to a lesser extent, may use energy swap agreements similar to those traded on the exchanges, such as crack spreads and crude oil options, to better match the specific price movements in our markets as opposed to the delivery point of the exchange-traded contract. These strategies are designed to minimize, on a short-term basis, our exposure to fluctuations in refining margins. The number of barrels of crude oil and refined products covered by such contracts will vary from time to time. These purchases and sales will be closely managed and be subject to internally established risk standards. The results of these hedging activities will affect refining costs of sales. We do not intend to engage in speculative futures or derivative transactions. Interest Rate Risk Our long term debt will be subject to interest rate risk. We will manage this rate risk by maintaining a mix of long term debt with fixed and floating rates. A 1% change in the interest rate on our long term debt could result in a $5.8 million change in earnings before interest and taxes. This determination is based on 1% of the $580 million total of the notes and the construction and term loans. We will be subject to interest rate risk on the floating rate bank term debt, but we will have the ability to call our floating rate debt. Under the common security agreement we may be required to hedge a substantial portion of our floating rate exposure under our secured construction and term loan facility. 36 Year 2000 Readiness As has been widely reported, many computer systems process dates based on two digits for the year of a transaction and many feared that computers would be unable to process dates in the year 2000 and beyond. There were many risks associated with the year 2000 compliance issue, including but not limited to, the possible failure of our systems and hardware with embedded applications. The failure of third parties, including our contractors, vendors, utilities and customers to remedy year 2000 issues also posed risks to our coker project. In particular, any failures by (1) Clark Refining & Marketing, which will be responsible for the management of our heavy oil processing facility and will purchase all our refined products, (2) Foster Wheeler USA, as contractor under the construction contract or (3) P.M.I. Comercio Internacional, as our principal supplier of oil, may have a material adverse effect on our businesses and operations. Clark Refining & Marketing began significant efforts to address its exposures related to the year 2000 issue in 1997 in order to operate and properly process information after December 31, 1999. Clark Refining & Marketing has expended $5.9 million from inception of its year 2000 systems remediation program through December 31, 1999. Clark Refining & Marketing believes that as of October 1999 its mission critical embedded processors at refineries and mission critical systems, including hardware and software, were ready for the year 2000. In addition, its mission critical business partners had represented that their mission critical systems were remediated. As of January 31, 2000, Clark Refining & Marketing had incurred only minor year 2000-related problems with its mission critical systems or processes and contingency plans handled these occurrences. More information on Clark Refining & Marketing's year 2000 program is discussed in Clark Refining & Marketing's Annual Report on Form 10-K/A for the year ended December 31, 1998 and Quarterly Report on Form 10-Q for the period ended September 30, 1999, as amended. The following information concerning Foster Wheeler Corporation is based solely on and derived solely from their annual report on Form 10-K for the year ended December 31, 1998, and their quarterly report on Form 10-Q for the third quarter of 1999, filed with the Commission. We have not conducted any independent investigation in this regard and therefore cannot assure the accuracy or completeness of such information. Foster Wheeler Corporation and its subsidiaries initiated year 2000 activities in 1996. In 1997, a formal year 2000 problem management strategy was prepared. The primary computerized reporting and control system used by Foster Wheeler Corporation and most of its subsidiaries, which was provided by J.D. Edwards, has been confirmed by the vendor to be year 2000 compliant. Although Foster Wheeler Corporation and its subsidiaries expect to be ready to continue their business activities without interruption by a year 2000 problem, they recognize that they depend on outsiders (such as suppliers, contractors and utility companies) to provide various goods and services necessary for doing business. Foster Wheeler Corporation has developed a contingency plan for itself, and has required each of its subsidiaries to do likewise. Each plan will address alternative arrangements to cope with year 2000 problems caused by others, and back-up strategies to follow if a subsidiary's software or equipment does not perform properly, even though it appears now to be year 2000 compliant. Most subsidiaries of Foster Wheeler Corporation completed their contingency plans by late September 1999 and the few that did not were expected to complete their plans by the end of November 1999. The failure to correct a year 2000 problem could result in an interruption in, or a failure of, certain normal business activities or operations. Foster Wheeler Corporation believes that the implementation of new business systems and the complete implementation of the business continuation plan should reduce the possibility of significant interruptions of normal operation. As of February 18, 2000, we have not had any material impact on our coker project related to the year 2000 issue and we have not been made aware of any material impact on Clark Refining & Marketing, Foster Wheeler USA, P.M.I. Comercio Internacional or any other third parties associated with the refinery upgrade project. We anticipate that our future year 2000 related costs will not have a material impact on our financial position or results of operations.

The refining margin is driven by the supply and demand for petroleum commodities. Refinery profitability is also influenced by the equipment configuration of the refinery, the refinery's operating cost structure and the refinery's access to crude oil and refined product markets. Demand for light refined products such as gasoline, diesel, kerosene/jet fuel grew at an annual rate of 4.2% from 1960 to 1973, according to the U.S. Department of Energy. However, demand for light refined products declined by 0.5% per year from 1973 to 1983. We believe that the combination of high oil prices for petroleum products due to the oil shocks of the early 1970's and the late 1970's, environmental regulations favoring cleaner burning fuels and gains in fuel efficiency caused consumption of light refined products to decrease. From 1983 through 1998, light refined product demand increased at a rate of 1.6% per year and, from 1993 through 1998, at 2.1% per year. We believe the renewed growth in light refined product demand is due to the expansion of U.S. vehicle fleet miles driven, increased seat miles flown on U.S. airlines and the reduced improvement in vehicle fuel efficiency due to consumer preference for light trucks and sport-utility vehicles. Demand for heavy refined products such as residual and other heavy oil grew at an annual rate of 4.0% from 1960 to 1978, according to the U.S. Department of Energy. We believe that the introduction of regulations restricting the use of residual oil in the late 1970's drastically reduced demand for residual oil, as demand decreased from approximately 3 million barrels per day in 1978 to approximately 0.9 million barrels per day in 1998, an annual decrease of 5.9%. During this same period, overall heavy refined product demand has decreased at only approximately 1% per year. From 1965 through 1978, crude oil distillation capacity utilization rates averaged approximately 89%, according to the American Petroleum Institute. We believe that sagging demand for light and heavy refined products was the primary cause that utilization rates fell to 69% in 1981. U.S. crude oil distillation capacity decreased from 18.1 million barrels per day in 1980 to 15.9 million barrels per day in 1998, according to the Oil & Gas Journal, as more than 40% of the refineries in the United States closed during this period. As a result of this decrease in capacity and the renewed increase in demand, U.S. crude oil distillation utilization rates increased during the 1980s and 1990s to approximately 95% in 1998. We believe U.S. crude oil distillation utilization rates may be approaching long term sustainable maximums due to the requirement for routine maintenance and the likelihood of unplanned downtime. U.S. Industry Outlook Purvin & Gertz expects annual growth in refined product demand in the U.S. to average over 1.2% through 2015. Purvin & Gertz further expects that growth in overall distillate in the United States will average near 2% over the next decade, before slowing to about 1.5% through the 2010 to 2015 period and gasoline demand growth will average 1% through 2015. We believe this growth reflects the continuing expansion of U.S. vehicle fleet miles driven, increased seat-miles flown on U.S. airlines with an offset for modest improvements in vehicle efficiency. Purvin & Gertz expects that total vehicle miles in the United States will increase by approximately 2.7% per year until the end of the decade. Thereafter, Purvin & Gertz expects growth in vehicle miles to average in the 1.7% range through 2015. Purvin & Gertz expects in the United States demand per capita for gasoline to decrease over the forecasted period largely as a result of efficiency improvement and continuing increases in per capita miles traveled. Purvin & Gertz forecasts that between 1998 and 2015 new car efficiency will improve by 5.3 miles per gallon. Purvin & Gertz also expects diesel and jet fuel demand to exhibit the strongest light refined product demand growth with 2% per year growth throughout the next decade. Purvin & Gertz expects demand for 38 residual fuel in the United States to continue declining trends throughout the next decade and demand for all other petroleum products, including other refined products and natural gas liquids, to increase at a rate of approximately 1.1% during the next 15 years. The following table summarizes the historical and expected growth patterns in demand for refined petroleum products in the United States.

Refinery Configurations Crude oil represents a refinery's largest single operating cost and is available in a range of prices depending on the equipment required for processing the crude oil, its potential yield of refined products, and the cost of transporting the crude oil to the refinery. Lighter and/or sweeter crude oil is priced higher than heavy and/or sour crude oil because it is easier to process and yields a higher-valued mix of products such as gasoline, diesel fuel, jet fuel and petrochemicals. The types of crude oil a refinery can process, as well as the yield of refined products from such crude oil, depends on the refinery "configuration." The configuration of a refinery denotes the number, specific types and the sequence of processing units. Processing units typically increase the value of their feedstocks by separating or changing the feedstocks' chemical structure. A refinery with a simple configuration chooses between running a lighter, more expensive crude oil to minimize low value residual fuel oil production, or running a heavier, less expensive crude oil and accepting this low valued production. Some refineries are unable to process heavy sour crude oil under any circumstances because of their location and/or design. The most sophisticated refinery configuration--the heavy coking refinery--can take advantage of lower priced, heavy sour crude oil while producing relatively little residual fuel oil and yielding a higher valued mix of products. 39 Heavy/Light Differential The economics of crude oil selection compares the discounts offered for lower quality crude oil to the gain on making higher value products instead of residual fuel. The refining margin of a heavy coking refinery is highly sensitive to the dollar per barrel price difference between heavy sour crude oil, such as Maya, and light sweet crude oil, such as West Texas Intermediate. This difference is often referred to as the "heavy/light differential." This measurement provides a reliable indication of the profitability advantage of a heavy coking refinery because a wider heavy/light differential typically results in lower cost feedstocks and a higher resulting refinery margin. According to Purvin & Gertz, from January 1988 through March 1999 the six month moving average of the heavy/light differential ranged from a high of $8.90 to a low of $3.76 with an average of $5.83 as shown in the following chart. [Chart] According to Purvin & Gertz, in the late 1980s, conversion capacity was fully utilized with little or no excess capacity. As a result, returns on investment for refiners motivated new investments in conversion capacity. By the early 1990s, the rate of addition of conversion capacity considerably exceeded the needed level. Many producers added this capacity with the intention of processing heavy sour crude into low sulfur diesel and reformulated gasoline. Many refiners found that the most economic way of accomplishing this was to combine various refinery modifications made in response to regulatory changes with expansions of conversion capacity. Since conversion capacity is generally the most profitable component of a refinery, many refiners believed that increasing it was the most effective way to maximize returns on product quality improvement investments. However, because so many refiners recognized the potential benefit of increasing conversion capacity, an overbuilding of capacity resulted. The overabundance of conversion capacity drove up demand for heavy feedstock and resulted in a narrowing of the heavy/light differential through 1995. Recovery in the heavy/light differential occurred in 1996 and 1997. Purvin & Gertz believes that while this recovery was due in part to temporary refinery operating problems at several major refinery units, which decreased the availability of conversion capacity, this recovery was primarily driven by the rising output of heavy sour crude oil in the Western Hemisphere. This increasing production of heavy sour crude oil resulted in severe price competition and residual fuel oil oversupply. The differentials reached a peak late in 1997 and early 1998 due to these factors. In April 1998, the trends began to reverse and the heavy/light differential began to narrow. This reversal was brought about by the confluence of a number of factors. These include the effects of the Asian financial crisis, which reduced demand for refined products and opened up capacity worldwide. In addition, low oil prices and high natural gas prices in the United States caused demand for residual fuel to increase rather dramatically. At the same time, export demand for residual fuel increased sharply due to El Nino related hydropower shortages in Mexico. Although the rate of increase in conversion capacity fell sharply after 1994, according to Purvin & Gertz several major projects are currently underway. In addition, several conversion projects are linked to supplies of 40 heavy sour crude oil from Venezuela and Mexico. Purvin & Gertz expects these conversion projects to absorb increases in heavy sour crude oil production. Net additions in recent years have been at a rate of 2% per year in the United States and nearly 4% worldwide. According to Purvin & Gertz, the recent heavy sour crude oil production cuts by Venezuela and Canada caused the heavy/light differential to narrow. At the same time, new conversion capacity was being brought on and was absorbing any excess heavy feedstock, thereby strengthening heavy feedstock prices and further narrowing the differential. In addition, high natural gas prices coupled with low residual fuel oil prices are encouraging the burning of residual fuel, thereby squeezing the heavy feedstock balance and narrowing the heavy/light differential even further. Even so, the differential averaged about $5.00 over the first six months of 1999. Purvin & Gertz believes domestic supply constraints in 1998 increased the price of West Texas Intermediate above the level which would otherwise be expected given the global supply-demand balance. Purvin & Gertz believes these constraints are in the process of being reversed and expects them to reduce the price of West Texas Intermediate. Because these supply constraints did not have a significant impact on the Gulf Coast price of Maya, Purvin & Gertz expects the heavy/light differential to contract as West Texas Intermediate prices decline relative to Maya. Purvin & Gertz believes that low demand for petroleum caused by the continuation of the Asian financial crisis will cause Venezuela and other OPEC producers to constrain production through 2000. Purvin & Gertz expects that production through 2000 will be further constrained under the terms of the March 1999 OPEC agreement. Mexico has agreed to constrain exports as well. According to Purvin & Gertz, these factors will tend to keep the heavy/light differential around $5.00 through 2000. Purvin & Gertz expects that after the year 2000, the heavy/light differential will begin to widen again since they expect all of the key factors determining the heavy/light differential to turn favorable: . as world economy, particularly Asia, improves, demand will grow rapidly; . crude oil prices increase as demand increases; . crude oil production increases, particularly heavy sour crude oil, as demand for OPEC crude oil increases since OPEC crude oil is generally heavier; . Venezuela, Mexico and Canada will expedite heavy oil production; and . light product demand and supply of heavy sour crude oil will likely increase faster than new conversion capacity can be added. Additional discussion of these conclusions are included in Purvin & Gertz's Crude Oil and Refined Product Market Forecast provided to you as Annex C. 41 EXISTING PORT ARTHUR REFINERY AND THE REFINERY UPGRADE PROJECT Existing Port Arthur Refinery The Port Arthur refinery is located in Port Arthur, Texas and is situated on an approximately 4,000 acre site, of which less than 100 acres are occupied by active operating units. The Port Arthur refinery has a current rated crude oil throughput capacity of approximately 232,000 barrels per stream day and the ability to process 100% sour crude oil, including up to 20% heavy sour crude oil, and has coking capabilities. The Port Arthur refinery has the ability to produce jet fuel, 100% low-sulfur diesel fuel, 55% summer reformulated gasoline and 75% winter reformulated gasoline. The Port Arthur refinery's Texas Gulf Coast location provides access to numerous cost effective domestic and international crude oil sources, and its products can be sold in central and eastern United States as well as in export markets. In February 1995, Clark Refining & Marketing purchased the Port Arthur refinery together with related terminals, pipelines and other assets from Chevron U.S.A. Products and some affiliated entities. Clark Refining & Marketing also acquired legal title to Chevron's chemicals facility and lube oil distribution facility, which are integrated with the Port Arthur refinery. The chemicals facility and the lube oil distribution facility are being leased to, and operated by, Chevron under long term leases providing for a nominal rent and containing a purchase option in favor of Chevron at a nominal purchase price. Clark Refining & Marketing also entered into agreements with Chevron and its affiliates providing for, among other things, various services and the sale and purchase of various refined products. Refinery Upgrade Project The purpose of the refinery upgrade project is to increase the ability of the Port Arthur refinery to process heavy sour crude oil. The business strategy of Clark Refining Holdings in undertaking the refinery upgrade project is to earn a higher margin on processing operations at the Port Arthur refinery and take advantage of our long term crude oil supply agreement with P.M.I. Comercio Internacional. The refinery upgrade project consists primarily of the construction of a new delayed coking unit, the installation of a new vacuum gas oil hydrocracking unit, the installation of a new sulfur complex and an expansion of the existing crude unit. Also included in the scope of the refinery upgrade project are various improvements to the infrastructure of the existing Port Arthur refinery and various modifications of existing processing units at the Port Arthur refinery. The Port Arthur refinery has several important characteristics that make it attractive for this type of investment, including its Gulf Coast location which provides excellent access to waterborne deliveries of Mexican crude oil and the fact that the Port Arthur refinery currently has much of the infrastructure and processing capability necessary to support an upgraded operation, which we believe lowers the capital cost. The following table highlights the impact we expect the refinery upgrade project to have on the Port Arthur refinery as a whole. The figures used under the heading "after" correspond to the data used by Purvin & Gertz in the base case financial model which is part of their report included in this prospectus as Annex B and represents the combined operations of Clark Refining & Marketing and Port Arthur Coker Company. The Port Arthur Refinery ----------------------- Before After Upgrade Upgrade ----------- ----------- Crude Oil Throughput Capacity (barrels per stream day)............ 232,000 250,000 Coker Throughput Capacity (barrels per stream day)............ 38,000 80,000 API Gravity............. 34(degrees) 24(degrees) Sulfur Processing Capacity............... 1.6% 3.1% Solomon Complexity Rating................. 12.2 15.9 Production (barrels per calendar day).......... 221,700 254,700 42 Throughput capacity is a term used to measure the capacity of a refinery or a particular processing unit at a refinery to process crude oil or another feedstock. API gravity is a method of differentiating crude oil quality which is closely correlated to product yields. In other words, the processing of a crude oil with a higher API gravity should result in increased product yields when compared to the processing of a crude oil with a lower API gravity. Solomon complexity rating is oil industry standard for comparing refineries based on the complexity of their configurations. A more "complex" refinery such as one with conversion capacity generally produces a more valuable mix of products. 43 COKER GROSS MARGIN SUPPORT MECHANISM IN OUR LONG TERM CRUDE OIL SUPPLY AGREEMENT The primary function of our coker project will be to allow the economical refining of Maya heavy sour crude oil into higher valued light intermediate products. These light products upon further processing and blending, are capable of being sold as home heating oil, on and off road diesel fuel or no. 2 fuel oil, gasoline and other similar products, which have historically been the highest value products derived from crude oil. Maya crude oil has historically been priced less than lighter, sweeter crude oil due its higher content of impurities and sulfur that make it more difficult to process, and without the proper processing equipment, result in a higher percent of historically low value residual products, such as no. 6 fuel oil, asphalt and other similar products. As such, the profitability of constructing coker equipment and our coker project is based on the price difference between residual products, as represented by no. 6 fuel oil in the coker gross margin support formula described below, and the ultimate products to which these residual products can be converted in the coking process, as represented by gasoline and no. 2 fuel oil below. If this spread between residual products and light products were very narrow for an extended period of time, the profitability of a coker project would be less and the risk to noteholders or a coker owner and operator would be greater. In negotiating our long term oil supply agreement with P.M.I. Comercio Internacional, we attempted to mitigate this risk substantially through the use of a coker gross margin support mechanism. This mechanism is composed of a formula that was designed to be a proxy for the economic opportunity of constructing coking equipment, which is compared to a negotiated differential guarantee amount of $15 per barrel. This mechanism is designed to moderate our coker gross margin fluctuations. The mechanism contains a formula that is intended to be an approximation for coker gross margin and is designed to provide for a minimum average coker gross margin during the first eight years following completion of the refinery upgrade project assuming we achieve completion by July 2001, and thus will not apply for the entire duration of the notes. The price we pay for Maya will be the regular price adjusted for a monthly adjustment amount based on the difference between the differential formula amount and a $15 per barrel differential guarantee amount. The differential formula amount is calculated as follows: Differential formula amount = (0.5 X RUL) + #2FO-(1.5 X #6FO) Where: RUL = average of U.S. Gulf Coast market prices for conventional 87 octane unleaded gasoline #2FO = average of U.S. Gulf Coast market prices for 0.2% sulfur no. 2 fuel oil #6FO = average of U.S. Gulf Coast market prices for 3% sulfur no. 6 fuel oil The gasoline and no. 2 fuel oil prices were selected as proxies for the prices that we can reasonably expect to receive for the light refined products produced by our coking unit. The no. 6 fuel oil price was selected as a proxy for coker feedstock prices because of its high degree of historical correlation with Maya prices. Our long term crude oil supply agreement also has a provision that is designed to compensate for changes in this historical correlation. We use the differential formula amount above to calculate the monthly adjustment amount as follows: Monthly adjustment amount = (differential formula amount-$15) X 36.6% X Our Maya delivered during the month. This amount is referred to in our long term crude oil supply agreement as a monthly surplus or shortfall, depending on whether it is a positive or negative number. This 36.6% factor is used because we expect that every 100 barrels of Maya processed through our crude unit will yield approximately 36.6 barrels of coker feedstock. 44 At the end of each calendar quarter, all monthly adjustment amounts, whether positive or negative, are netted under a mechanism set forth in our long term crude oil supply agreement, resulting in a price adjustment applicable to Maya to be purchased in the succeeding calendar quarter. The discount applied to the price of Maya in any quarter may not exceed $30 million. The premium applied to the price of Maya in any quarter may not exceed the lesser of $20 million or the net aggregate amount of shortfalls for the prior period. The net adjustment amount, whether positive or negative, existing at the end of the period during which the coker gross margin support is available will be applied over the remaining term of the agreement, after giving effect to the operation of the differential mechanism in the last period. The discount we receive in any quarter will not exceed $30 million and the premium we pay in any quarter will not exceed $20 million. If the differential formula amount is calculated over the period 1987-1998 and regressed against the historical heavy/light differentials, the mathematical result implies that the $15 per barrel differential guarantee amount would correspond to a heavy/light differential of $5.94 per barrel. This is $0.24 per barrel above the historical average heavy/light differential of $5.70 per barrel over the same period. Therefore the coker gross margin support mechanism in our long term crude oil supply agreement would have added to our coker gross margin during that period. According to Purvin & Gertz, the price adjustment mechanism in our long term crude oil supply agreement serves as a suitable method of stabilizing coker gross margin fluctuations. Below is a sample quarterly calculation of the operation of the price adjustment mechanism contained in our long term crude oil supply agreement, based on the year 2001 price forecast by Purvin & Gertz and assuming quarterly Maya volume of 13.8 million barrels: Differential Formula Amount = (0.5 x $19.48) + $18.40 - (1.5 x $10.22) = $12.81 Differential Guarantee Amount -$15.00 ------- Shortfall per barrel $ 2.19 Quarterly Maya Volume (millions of barrels) 13.8 Coker Feedstock Factor x 0.366 ------- Eligible Volume (millions of barrels) 5.1 Coker Gross Margin Shortfall per barrel of feedstock x$ 2.19 ------- Discount due (millions of dollars) $ 11.0 Quarterly Maya Purchase Cost without discount $10.88 Quarterly Maya Purchase Cost after application of discount $10.08 See "Description of Our Principal Project Documents--Long Term Crude Oil Supply Agreement" for a more complete and detailed discussion of our crude oil supply arrangement. You should also read "RiskFactors--Market Risks" regarding the risk that the coker gross margin support mechanism may not adequately protect against all fluctuations in the relative prices of heavy sour crude oil and refined products. See Tables V-12, V-14, V-16, V-17, V-19, V-21, V-23, V- 25, V-26, V-27 and V-28 in Annex B to this prospectus for other projection cases produced by Purvin & Gertz that include alternative calculations of the coker gross margin adjustment mechanism. 45 OUR COKER PROJECT Our coker project will use delayed coking technology to enable the Port Arthur refinery to process increased volumes of heavy sour crude oil. We expect the total cost of constructing our new units described below and completing the additional improvements that comprise our coker project to be $715 million, including an allowance for estimated price escalation and contingencies. Our Portion of the Refinery Upgrade Project Delayed Coker. Our new 80,000 barrel per stream day delayed coking unit will be equipped with six coke drums. This unit converts vacuum tower bottoms from the refinery's crude unit through thermal cracking process into lighter, more valuable products, principally heavy gas oil that is fed to the hydrocracker, light gas oil that is blended into distillate after further processing, naphtha feed for further processing, butane/butylene, propane/propylene and fuel gas. Petroleum coke is a byproduct of this process and is sold principally for utility fuel. According to Purvin & Gertz, delayed coking technology has been utilized for well over 50 years and is one of the most widely used processes to upgrade low value heavy residue into higher value light products. Our delayed coking unit will use a well established and commercially proven Foster Wheeler USA design. According to Purvin & Gertz, this design has the benefit of the prior experience of Foster Wheeler USA, which has designed five coker units with a capacity of 75,000 barrels per day or greater, and it should result in more favorable product yields and lower operating costs. Vacuum Gas Oil Hydrocracker. Our new vacuum gas oil hydrocracker is designed to process 35,000 barrels per day of feedstock consisting of heavy gas oil from our coking unit and virgin vacuum gas oil and light cycle oil from other refinery processing units. Our hydrocracker is designed for the conversion of the heavy feedstock into at least 50% light products. According to Purvin & Gertz, full hydrocracker conversion of the vacuum gas oil is not required since Clark Refining & Marketing's existing fluid catalytic conversion unit has the capacity to convert the remaining vacuum gas oil. This allows our hydrocracker to have a smaller second stage reactor than is typical for vacuum gas oil hydrocrackers, which reduces our capital costs. We will license our hydrocracker design from Chevron Research and Technology Company which is also providing a process guarantee for our hydrocracker. According to Purvin & Gertz, vacuum gas oil hydrocracking is a well established and commercially proven technology, and the expected yields from our new hydrocracker can be achieved. Sulfur Recovery Units. Our new sulfur complex will operate in parallel with existing sulfur recovery units at the Port Arthur refinery to process the incremental hydrogen sulfide that will result from the processing of increased quantities of heavy sour crude oil at the Port Arthur refinery. Our sulfur complex will consist of: . a new dual train sulfur recovery unit with a total capacity of 417 long tons per stream day, . a new tailgas cleanup unit that uses licensed technology from Shell Oil Company called Shell Claus Offgas Treater or "SCOT", . a new sour water stripper and . a new amine treating unit. According to Purvin & Gertz, the technology selected for our new sulfur recovery complex will result in a well-designed unit with adequate sulfur removal capacity to support the expected requirements of the Port Arthur refinery. Infrastructure Improvements. Our coker project will also include the following additional infrastructure improvements at the refinery: . interconnecting of process units and utility piping between our units; . converting existing tanks into coker feed tanks; . constructing a new dedicated flare for our units; 46 . constructing a new substation to supply power to our new units; . constructing a new control unit for our units; and . installing truck and rail loading facilities for sulfur. Clark Refining & Marketing's Portion of the Refinery Upgrade Project In addition to the new processing units described above which comprise our coker project, we are leasing existing processing units from Clark Refining & Marketing. In connection with this lease, Clark Refining & Marketing is obligated to make modifications and infrastructure improvements during 1999 and 2000 to integrate these existing processing units with our coker project at an estimated cost of up to $120 million. In return, we are obligated to make rental payments to Clark Refining & Marketing for our use of these modified units. As of December 31, 1999, Clark Refining & Marketing had expended approximately $51 million towards this commitment. According to Purvin & Gertz, these modifications to be undertaken by Clark Refining & Marketing are a group of routine, small refinery projects normally carried out during turnarounds and do not present a major risk to the successful start-up, operation or integration of our coker project. Modification of Crude Unit. The existing crude/vacuum unit, which is presently designed to process 232,000 barrels per stream day of light to medium sour crude oil, will be modified to process 250,000 barrels per stream day. These modifications include changes to the process exchangers to provide more preheat to the crude unit, upgrading the vacuum unit heater and miscellaneous pumps and piping. These activities will be completed prior to start-up of our new units. The crude unit revamp design is adequate to support the processing of the expected increased volume of heavy sour crude oil. Modification of Hydrotreaters. The existing distillate and kerosene hydrotreating units at the Port Arthur refinery are being revamped to increase capacity for handling the higher sulfur distillate products that will be produced by the increased volume of heavy sour crude oil. These modifications involve increasing the size of reactors and catalyst volume through replacement of reactors. In fact, replacement of reactors in one of the hydrotreaters has already been completed. These modifications will be completed three to six months prior to start-up of our coker project. Infrastructure Improvements. Clark Refining & Marketing will also undertake the following additional infrastructure improvements at the refinery: . interconnecting of process units and utility piping between our and their units; . upgrading existing crude handling facilities, including a new crude oil pumping station; . expanding the firewater loop; . upgrading the electrical system; and . modifying coke handling facilities. The New Hydrogen Plant To provide the hydrogen necessary to the refinery upgrade project, Air Products has agreed to construct a new 100 million standard cubic feet per stream day hydrogen supply plant at the Port Arthur refinery on land leased from Clark Refining & Marketing. This new hydrogen supply plant is intended to enable Air Products to meet its obligations under its hydrogen supply agreement with us. The Air Products hydrogen supply plant is also intended to supply hydrogen, steam and electricity to Clark Refining & Marketing for use at the Port Arthur refinery. 47 Air Products is obligated to us to ensure that the hydrogen supply plant is ready to operate no later than December 2000, the date when we expect our heavy oil processing facility to first need hydrogen. Purvin & Gertz believes that this is achievable and that it is likely that the hydrogen supply plant will be constructed and ready for start-up before our coker project. For a description of the hydrogen supply agreement, please see "Description of Our Principal Project Documents--Hydrogen Supply Agreement." The hydrogen supply plant is being built principally to provide us and Clark Refining & Marketing with our required supply of hydrogen. The estimated total cost of constructing the hydrogen supply plant is $125 million and is being funded by Air Products. We will have no rights, ownership or otherwise, relating to the hydrogen supply plant. Process Flow at the Port Arthur Refinery The following diagram illustrates the major components of the refinery upgrade project, showing (1) our new processing units, referred to in this prospectus as the coker project, (2) the processing units we are leasing from Clark Refining & Marketing and which Clark Refining & Marketing is upgrading and (3) the new hydrogen supply plant that Air Products is constructing and will own at the Port Arthur refinery. [Process Flow Chart] 48 Construction of the Refinery Upgrade Project The refinery upgrade project was formally initiated in April 1998, and Clark Refining & Marketing began construction in September 1998 pursuant to a reimbursable construction contract with Foster Wheeler USA. We purchased the work in progress under such contract related to our coker project in part with funds from the sale of the outstanding notes and have entered into our construction contract with Foster Wheeler USA to complete our coker project. For a more detailed summary of this contract, see "Description of Our Principal Project Documents--Construction Contract." Pursuant to our services and supply agreement, Clark Refining & Marketing is managing and supervising the construction of our new units and other equipment and overseeing the performance of Foster Wheeler USA under our construction contract. In addition, Clark Refining & Marketing is performing all our obligations, other than payment obligations, under our construction contract with Foster Wheeler USA, including all project management and construction management functions, quality surveillance, performance of start-up activities, provision of needed water and utilities and provision of all necessary feedstreams for operation of our coker project during start-up and performance testing. For a more detailed summary of the services and supply agreement, see "Description of Our Principal Project Documents-- Services and Supply Agreement." Pursuant to our facility and site lease with Clark Refining & Marketing, if Clark Refining & Marketing does not complete the upgrades to existing refinery processing units which we are leasing from them by October 2000, we have the right to complete these modifications at Clark Refining & Marketing's expense so that the overall completion of the refinery upgrade project is not delayed. Clark Refining & Marketing has entered into a reimbursable construction contract with Foster Wheeler USA for performance of the majority of these modifications and Clark Refining & Marketing's portion of the other refinery improvements. These modifications and improvements will be paid for by Clark Refining & Marketing. Clark Refining & Marketing arranged for its lenders to provide a standby letter of credit for $97 million to Foster Wheeler USA to ensure that funds are available for payments to Foster Wheeler USA under its reimbursable construction contract. Foster Wheeler USA has also agreed not to draw on the letter of credit for amounts due to it unless Purvin & Gertz, in its role as independent engineer, has certified that the work related to the requested drawing has been performed and the amounts requested are due and payable. As of February 29, 2000, the letter of credit had been reduced to $79 million based on payments made to Foster Wheeler USA. For a more detailed summary of the facility and site lease and the reimbursable construction contract, see the applicable sections under "Description of Our Principal Project Documents."

October 2000 December 2000 December 2000 Operation of our Heavy Oil Processing Facility Pursuant to our services and supply agreement with Clark Refining & Marketing, Clark Refining & Marketing will provide to us a number of services and supplies needed for operation of our heavy oil processing facility. Clark Refining & Marketing is required to provide all such services and supplies in accordance with specified standards, including prudent industry practices. 49 Operation and Management Port Arthur Coker Company employees will operate the processing units comprising our coker project. Clark Refining & Marketing will supervise and train our employees, operate the remaining units comprising our heavy oil processing facility and be responsible for the management of our heavy oil processing facility. In addition, Clark Refining & Marketing is responsible for managing our crude oil purchases and the transportation of such oil to the Port Arthur refinery. Clark Refining & Marketing is also obligated to procure and manage supply contracts on our behalf for the portion of light crude oil that is necessary for processing heavy crude oil at the refinery and for an alternative supply of crude oil should Maya no longer be available to us pursuant to our long term crude oil supply agreement with P.M.I. Comercio Internacional. Maintenance Heavy Oil Processing Facility. Clark Refining & Marketing is responsible for routine, preventative and major maintenance for all portions of our heavy oil processing facility. Our heavy oil processing facility is designed for continuous operation, and maintenance work will be performed on a regular basis by Clark Refining & Marketing. In this regard, Clark Refining & Marketing intends to use monitoring and preventative maintenance measures to ensure reliable operations with minimal failures and unexpected shutdowns. Maintenance of our heavy oil processing facility will require periodic shutdown of various processing units. In particular, the coker, hydrocracker and sulfur complex will require three-week shutdowns for maintenance every four years. Every six months we will set aside a portion of our revenues, to the extent available, to pay for turnaround expenses expected to be incurred during our next scheduled maintenance turnaround of the new processing units. Port Arthur Refinery. Clark Refining & Marketing is also obligated under our services and supply agreement to operate and maintain the other portions of the Port Arthur refinery owned by it in a manner that ensures its ongoing ability to perform its obligations to us and that is consistent with specified standards and the efficient operation of our heavy oil processing facility. To remain competitive with other refiners and to preserve operating conditions at the Port Arthur refinery, Clark Refining & Marketing has invested significant amounts in the maintenance of the major processing units at the refinery. Clark Refining & Marketing generally has conducted maintenance turnarounds in accordance with the refinery's normal maintenance cycles in an effort to minimize disruptions to the refinery's operations. Clark Refining & Marketing is obligated to continue to coordinate the scheduling and performance of all maintenance turnarounds of processing units at the Port Arthur refinery, including turnarounds of units comprising our heavy oil processing facility, in accordance with industry standards and in a manner that, when possible, minimizes operational disruptions to, and economic impact on, when possible, both Clark Refining & Marketing and us. Infrastructure and Utilities We share common utilities and infrastructure with Clark Refining & Marketing at the Port Arthur refinery. As part of the services provided by Clark Refining & Marketing pursuant to our services and supply agreement, Clark Refining & Marketing provides us with utilities and other support services using, among others, the following refinery facilities: . the electrical distribution system; . the steam distribution system; . the natural and fuel gas distribution system; . the nitrogen distribution system; . the waste management and wastewater treating facilities; . the analytical laboratory; . crude oil storage facilities; 50 . the refinery pipeline system; . water and air distribution facilities; and . warehouse storage. Other Services and Supplies Clark Refining & Marketing will also provide us with all feedstocks (other than crude oil), catalysts, chemicals and other materials necessary for the operation of our heavy oil processing facility and a number of other services, including contract management services, procurement services, personnel management services, security services and emergency response services. Processing Arrangements Under our services and supply agreement, Clark Refining & Marketing also has a right of first refusal to require us to process crude oil for them in an amount equal to the portion, if any, of the processing capacity of our heavy oil processing facility that exceeds the amount we need to process the Maya available to us under our long term crude oil supply agreement with P.M.I. Comercio Internacional or an equivalent amount available to us under an alternative supply arrangement. Clark Refining & Marketing will pay us a processing fee for any of its crude oil and other feedstocks that we process under this right of first refusal. We expect this portion to be approximately 20% of the processing capacity of our heavy oil processing facility. Sale of Our Products Pursuant to our product purchase agreement with Clark Refining & Marketing, Clark Refining & Marketing is unconditionally obligated to accept and pay for all final and intermediate products of our heavy oil processing facility that we tender for delivery. Clark Refining & Marketing, as our sole customer, has the right to request that the heavy oil processing facility produce a certain mix of products. This right, however, is subject to specified limitations that are designed to ensure: . that we utilize the entire amount of Maya available to us under our long term crude oil supply agreement or an equivalent amount from an alternative supplier, . that we are able to service the notes and our other debt obligations on an ongoing basis and . that the operations of the Port Arthur refinery are optimized in a manner that is mutually beneficial to us and Clark Refining & Marketing and that does not benefit Clark Refining & Marketing at our expense. Our Competition and Marketing Environment We have not entered into any other arrangements for the sale of our refined products. Thus, our product purchase agreement is our sole source of revenue from the sale of refined products. According to Purvin & Gertz, however, we are located in the most liquid refined products market in the world and if Clark Refining & Marketing no longer meets its purchase obligations to us, our intermediate and final refined products would be readily marketable to third parties at somewhat discounted prices. For a more detailed discussion of these conclusions you should read the sections captioned "Conclusions--Stand-Alone Case" and "Economic Model--Stand-Alone Case" in Annex B to this prospectus. We have no crude oil reserves and are not engaged in exploration and production activities. We will obtain our crude oil requirements pursuant to our long term crude oil supply agreement with P.M.I. Comercio Internacional, on the spot market from unaffiliated sources or from Clark Refining & Marketing pursuant to our services and supply agreement. We believe that we will be able to obtain adequate crude oil and other feedstocks at generally competitive prices in the foreseeable future. 51 Our feedstocks and refined products are principally commodities and the pricing of such feedstocks and refined products under our services and supply agreement and product purchase agreement is intended to reflect market prices. As a result, our operating cash flows and earnings will be significantly affected by a variety of factors beyond our control, including the supply of and demand for crude oil, gasoline and other refined products which in turn depend on, among other factors, changes in domestic and foreign economic conditions, weather patterns, political affairs, crude oil production levels, the rate of industry investments, the availability of imports, the marketing of competitive fuels and the extent of government regulations. Also relevant are seasonal fluctuations with generally stronger operating cash flows and earnings expected during the higher transportation-demand periods of the spring and summer and weaker operating cash flows and earnings expected during the fall and winter. We also expect our operating cash flows and earnings to be affected by the competitive position of the Port Arthur refinery. The refining segment of the oil industry is highly competitive. Many of the Port Arthur refinery's principal competitors are owned by integrated multinational oil companies that are substantially larger than Clark Refining & Marketing. Because of their diversity, integration of operations, larger capitalization and greater resources, these major oil companies may be better able to withstand volatile market conditions, more effectively compete on the basis of price and more readily obtain crude oil in times of shortages. The Port Arthur refinery's principal competitors are 28 other refineries located on the U.S. Gulf Coast. In Purvin & Gertz's opinion, the refinery upgrade project will transform the Port Arthur refinery into one of the top five refineries in this Gulf Coast market in terms of competitiveness and heavy crude oil conversion capacity. Environmental Matters General Our operations are subject to extensive federal, state and local environmental, health and safety laws and regulations, including those governing discharges to the air and water, the handling and disposal of solid and hazardous wastes, and the remediation of contamination. The failure to comply with such laws and regulations can lead to, among other things, civil and criminal penalties and in some circumstances the temporary or permanent curtailment or shutdown of operations. The nature of the refining business exposes us to risks of liability due to the production, processing, storage and disposal of materials that can cause contamination or personal injury if released into the environment. Pursuant to our services and supply agreement, Clark Refining & Marketing has committed to take actions necessary to cause us to comply with these laws and regulations. We expect that the nature of the refining business will make us subject to increasingly stringent environmental and other laws and regulations that may increase the costs of operating our heavy oil processing facility above currently projected levels. We may be required to make future expenditures to comply with more stringent standards for air emissions, wastewater discharge and the remediation of contamination. As our coker project is integrated with the operations of the Port Arthur refinery, any developments in environmental laws that adversely impact Clark Refining & Marketing's operations could also adversely affect our financial condition or results of operations. It is difficult to predict the effect of future developments in these laws and regulations on our financial condition or results of operations. We are unaware of any environmental or health and safety liabilities and expenses that are reasonably likely to have a material adverse effect on our results of operations but cannot assure you that such liabilities and expenses will not occur. You should read "Risk Factors--Environmental Risks for a discussion of the risk that environmental concerns pose to our Coker Project." Existing Conditions Environmental laws typically provide that the owners or operators, including lessees, of contaminated properties may be held liable for their remediation. Such liability is typically joint and several, which means 52 that any responsible party can be held liable for all remedial costs, and can be imposed regardless of whether the owner or operator caused the contamination. The Port Arthur refinery is located on a contaminated site. Under the 1994 purchase agreement between Clark Refining & Marketing and Chevron Products USA relating to the Port Arthur refinery, Chevron retained environmental remediation obligations regarding pre-closing contamination at over 97% of the refinery site. Clark Refining & Marketing assumed responsibility for any remediation that is required in and under the remaining approximately 3% of the refinery site, which consists of specified areas that extend 25 to 100 feet from active operating units, including soil and ground water and, encompasses less than 50 acres of the total Port Arthur refinery site surface area. Clark Refining & Marketing has estimated its liability for remediation of groundwater and soil in these areas at $27 million. Chevron is obligated to remediate the contamination in the areas for which it has retained responsibility as and when required by law, in accordance with remediation plans negotiated by Chevron and the applicable federal or state agencies. We evaluated the cost associated with remediation of the groundwater and soil of the land that we are leasing within the boundaries of the Port Arthur refinery and estimate remedial costs relating to our coker project site at $1.6 million. Clark Refining & Marketing has agreed to retain liability regarding contamination existing at the coker project site and has indemnified us against such liabilities. However, if Clark Refining & Marketing breaches its remediation obligations, we could incur substantial additional costs in remediating the contamination, which could impair our ability to make payments on the notes and our other debt when due. We believe that the remediation costs relating to contamination at our coker project site would be deferred until the final decommissioning of our coker project. However, actual remediation costs, as well as the timing of such costs, are dependent on a number of factors over which neither we nor Clark Refining & Marketing has control, including changes in applicable laws and regulations, priorities of regulatory officials, interest from local citizens groups and development of new remediation methods. Permits, Applications and Status In August 1998, Clark Refining & Marketing amended its flexible air emissions permit from the Texas Natural Resource Conservation Commission to allow Clark Refining & Marketing to undertake the refinery upgrade project. At our and Clark Refining & Marketing's request, the Texas Natural Resource Conservation Commission amended Clark Refining & Marketing's flexible air emissions permit and issued to us a new air emissions permit in May 1999. As a result, we now hold an air emissions permit from the Texas Natural Resource Conservation Commission which covers construction and operation of our new processing units. Clark Refining & Marketing holds an amended flexible air permit from the Texas Natural Resource Conservation Commission which covers other processing units and facilities at the Port Arthur refinery including the processing units that we are leasing from Clark Refining & Marketing and their other facilities which we have a right to use. Under applicable environmental regulations, we have the right to operate such equipment and facilities pursuant to Clark Refining & Marketing's existing permits. We also have a standby air emissions permit, which contains a provision permitting such permit to be activated by us to cover the entire Port Arthur refinery, including such equipment and facilities, upon notice to the Texas Natural Resource Conservation Commission. Under our supply and services agreement with Clark Refining & Marketing, we have agreed not to exercise our rights to activate this permit unless the permit is required to allow us to continue our operation of our units. Proposed Gasoline Sulfur Specifications On May 13, 1999, the United States Environmental Protection Agency published a proposed rule that would require on a nationwide basis a substantial reduction in the sulfur content of gasoline. A final rule establishing the new gasoline sulfur specifications was finalized in December 1999. However, according to Purvin & Gertz, with our new hydrocracker and the existing vacuum gas oil hydrotreater, the Port Arthur refinery will likely only require additional hydrotreating on some gasoline blendstock streams to allow for the production of gasoline meeting the new specifications. We and Purvin & Gertz expect this capital expenditure 53 to be substantially less than $50 million through the use of idle equipment currently located at the Port Arthur refinery. MTBE Recent concerns regarding groundwater contamination by methyl tertiary butyl ether, also known as "MTBE," a gasoline additive, have prompted a panel of the Environmental Protection Agency to recommend that the U.S. Congress enact a ban on MTBE usage in gasoline. Similarly, the governor of California recently signed an executive order regarding a ban on MTBE usage in gasoline in the next few years. If a ban on MTBE usage were to spread throughout the United States, we would be prohibited from utilizing MTBE in gasoline blends. However, we do not plan to produce MTBE and Purvin & Gertz has concluded that a ban on MTBE usage would not have a material effect on our operations and cash flow or the competitiveness of the Port Arthur refinery. Insurance Pursuant to our financing documents, Port Arthur Coker Company is required to maintain a specified minimum level of insurance in connection with our coker project. In this regard, we are required to keep all our property of an insurable character insured with such coverage and in such forms and amounts as are customarily provided for facilities similar in size and type to our coker project. Such insurance includes insurance against sudden and accidental environmental damage, delay in start-up insurance and business interruption and contingent business interruption insurance. For more description of the insurance we are required to maintain, see "Description of Our Principal Financing Documents--Common Security Agreement--Insurance." Legal Proceedings None of Port Arthur Coker Company, Port Arthur Finance, Sabine River nor Neches River is currently a party to any pending legal proceedings, nor do we have actual knowledge of any threatened legal proceeding. Property Port Arthur Coker Company, Port Arthur Finance and Sabine River lease office space from Clark Refining & Marketing at 1801 S. Gulfway Drive, Office No. 36, Port Arthur, Texas 77640, where we have our principal executive offices. Our coker project will be located on a subdivided site totaling less than 50 acres within the Port Arthur refinery. Port Arthur Coker Company has entered into a long term fully-prepaid ground lease with Clark Refining & Marketing for such site. Pursuant to such ground lease, Clark Refining & Marketing has also granted us an easement over the remainder of the Port Arthur refinery which is owned by Clark Refining & Marketing and the right to use other specified facilities and equipment at the refinery. Port Arthur Coker Company is also leasing Clark Refining & Marketing's crude unit, vacuum tower and one naphtha and two distillate hydrotreaters and the site on which they are located at the Port Arthur refinery pursuant to a facility and site lease. Pursuant to this facility and site lease, Clark Refining & Marketing has also granted us an easement across the remainder of the Port Arthur refinery property owned by it, a portion of Clark Refining & Marketing's dock adjacent to the Port Arthur refinery and specified pipelines and crude oil handling facilities needed to transport crude oil from docking facilities in Nederland, Texas, to the Port Arthur refinery. Both of these leases have an initial term of 30 years which may be renewed at our option for five additional renewal terms of five years each. Employees Port Arthur Coker Company expects to employ approximately 50 full-time employees to operate our new units once our coker project is fully operational, but currently only employs one individual who performs accounting services. Port Arthur Finance, Sabine River and Neches River currently have no employees and do not expect to have any employees. 54 INDEPENDENT ENGINEER'S REPORT SUMMARY Selected conclusions of Purvin & Gertz's independent engineer's report are summarized below. Purvin & Gertz's estimates for the coker project included in this prospectus were not prepared with a view toward compliance with published guidelines of the American Institute of Certified Public Accountants or generally accepted accounting principles. Neither our independent auditors, nor any other independent accountants, have compiled, examined or performed any procedures with respect to our or Purvin & Gertz's estimates regarding our coker project contained in this prospectus, nor have they expressed any opinion or any form of assurance on such information or its achievability, and assume no responsibility for, and disclaim any association with, the aforementioned estimates. These figures represent Purvin & Gertz's best estimates of operating and financial results of our coker project assuming the completion of our coker project and expected mode of operation. You should read the entire report which is set forth as Annex B to this prospectus. In Purvin & Gertz's opinion, the refinery upgrade project will transform the Port Arthur refinery into one of the top five refineries on the Gulf Coast in terms of competitiveness and heavy crude oil conversion capacity. Based on their review of the refinery upgrade project, they have reached the following technical, commercial/marketing and financial conclusions: Technical . The design of the major new units to be installed at the Port Arthur refinery, specifically our delayed coking and the hydrocracker units, are based on licensed technology that is well-established and commercially proven. . The size and configuration of the new process units should integrate well with the Port Arthur refinery. . The refinery upgrade project capital cost estimate provided by Foster Wheeler USA and Clark Refining & Marketing is reasonable and includes all relevant items based on their review of the estimate. . The contingency and escalation allowance included in the estimate is adequate at this stage of the refinery upgrade project. . The refinery upgrade project schedule of 31 months, from April 1998 to mechanical completion in November 2000, is achievable. . There are no apparent site conditions including known underground obstructions or contamination that would lead to major cost overruns. . The refinery upgrade project will have a useful life of at least 20 years extending well beyond the term of the debt financing. . Foster Wheeler USA is a reputable engineering contractor experienced in designing and constructing refining and petrochemical facilities. Foster Wheeler USA is well qualified for the proposed assignment and has the resources and financial strength necessary to fulfill their obligations under our construction contract and their reimbursable construction contract with Clark Refining & Marketing for their portion of the refinery upgrade project. . Our construction contract is favorable to us, is suitable for this type of financing, and provides adequate protection to us for cost overruns, completion risk, integration risk and inefficiencies. . The required performance and reliability tests have been structured to validate cash flow availability in order to support our anticipated debt capacity and, if not, to cause Foster Wheeler USA to buydown our debt to adjust it according to the reduced debt service capacity. 55 . The liquidated damages cap of $145 million represents up to $70 million of delay damages and up to $75 million of buydown damages for inefficiencies and is adequate for this type of project. . The Clark Refining & Marketing portion of the refinery upgrade project, including the crude oil unit and hydrotreater modifications and other offsites and utilities to be undertaken by Foster Wheeler USA are a group of relatively routine small refinery projects normally carried out during turnarounds or during refinery operations, which Purvin & Gertz expects will not present a major risk to the successful start-up, operation and integration of our coker project. . Clark Refining & Marketing is an experienced fuels refinery operator currently processing Maya, operating two existing cokers at the Port Arthur refinery and is well qualified to manage operations at the Port Arthur refinery. . Clark Refining & Marketing's crude oil import infrastructure and Sun Pipe Line Company's Nederland terminal and connecting pipelines to the Port Arthur refinery are adequate to support the volumes of imported Maya and other crude oil contemplated for the refinery upgrade project's operation. Several pipeline and terminal alternatives also exist to deliver crude oil to the Port Arthur refinery if required. . Air Products is a reliable hydrogen producer and the hydrogen supply plant will be constructed in a timely manner and will produce the required hydrogen and utilities. Approximately 50% of the required hydrogen can be supplied by Air Products via pipeline as a backup, if necessary. Commercial and Marketing . The long term crude oil supply agreement was designed to minimize the effect of adverse refining cycles, and as a result, establish more stable cash flow for us. In order to effect stable cash flows, our long term crude oil supply agreement contains a formula that is intended to be an approximation for coker gross margin and is designed to provide for a minimum average coker gross margin over the first eight years following completion of the refinery upgrade project. The mechanism guarantees an average minimum $15.00 per barrel differential formula related to coker gross margin via price adjustments on Maya. . If the differential formula amount is calculated over the August 1987 to December 1998 period and regressed against the historical West Texas Intermediate/Maya differential, the mathematical results implies that the $15 per barrel is equivalent to the West Texas Intermediate/Maya differential of $5.94 per barrel. This is $0.24 per barrel above the historical average West Texas Intermediate/Maya differential of $5.70 per barrel over the same period. Purvin & Gertz has reviewed our long term crude oil supply agreement and believes the mechanism serves as a suitable method of stabilizing coker gross margin fluctuations. . Clark Refining & Marketing will offtake all the intermediate and final products produced by our operations and will provide services to us on a routine contractual basis. Clark Refining & Marketing will be able to incorporate the products from our operations into the Port Arthur refinery and has considerable experience in selling finished products into the Gulf Coast market. . The product offtake, operation, maintenance and other services provided under the contracts between Clark Refining & Marketing and Port Arthur Coker Company contemplate products and services that are priced to reflect arms-length mechanisms and market-based prices and contain fair market terms. . Based on Purvin & Gertz's analysis of the worldwide heavy oil supply and demand fundamentals and plans and objectives stated by PEMEX and the Venezuelan national oil company, Purvin & Gertz forecasts that heavy sour crude oil production will continue to increase through the term of our financing. The crude oil heavy/light differential is forecast to average $6.00 per barrel or above in constant 1999 dollars over the same period. This is equivalent to a $15.16 per barrel coker gross margin as defined by the differential formula in the long term crude oil supply agreement. This forecast is consistent with the expectation that coker projects will continue to develop in an orderly fashion in line with the expected heavy sour crude oil production increases. 56 . P.M.I. Comercio Internacional and PEMEX have sufficient Maya reserves to fulfill the supply obligation under our long term crude oil supply agreement. The risk of diversion of Maya away from Port Arthur Coker Company is thought to be minimal because: . Mexico is increasing its production of Maya from 1.6 million barrels per day to 2.0 million barrels per day; . the number of other sour crude oil refineries able to process Maya are very limited; . the demand for heavy sour crude oil outside the United States is small and Purvin & Gertz does not expect it to change during the forecast period; and . the netback for heavy sour crude oil shipments to Europe or Asia is low relative to U.S. Gulf Coast deliveries. . Although the refinery upgrade project is designed to process Maya as its primary feedstock, it will have the flexibility to process other similar quality heavy sour crude oils and will be able to achieve essentially equivalent economics to the base case projections with minimal changes to configuration excluding any benefits of the coker gross margin guarantee in our long term crude oil supply agreement. . The shutdown of the Port Arthur refinery is an extremely remote possibility due to its competitiveness post-completion of the refinery upgrade project. . The terms of each of the product purchase agreement, the services and supply agreement, the ground lease and the facility and site lease are as favorable to Clark Refining & Marketing and to Port Arthur Coker Company, in all material respects, as terms that would be obtainable at this time for a comparable transaction or series of similar transactions in arm's length dealings with a party who is not an affiliate. Payments to be made by Clark Refining & Marketing to us under the product purchase agreement and the services and supply agreement are fair consideration for the products acquired or services received. . The consideration we paid Clark Refining & Marketing for our assumption of the long term crude oil supply agreement, our acquisition of work in progress on our coker project and Clark Refining & Marketing's reduction of the permissable emissions levels under one of its air emissions permits in order to allow us to obtain our air permit was equal to the fair market value of these assets. The rental payments Clark Refining & Marketing received under the ground lease and will receive under the facility and site lease are equal to the fair market value rental payments of the property leased. Financial Projections . The Purvin & Gertz base case assumes that our new units are operated as part of the Port Arthur refinery. Assuming a specified price forecast, estimated average operating cash flow over our initial 11-year operating period is approximately $228 million and the after-tax cash flows generated by our operations will be sufficient to repay our debt obligations, including scheduled principal amortization and interest, with a minimum debt service coverage ratio of 2.0:1.0 and an average debt service coverage ratio of 2.4:1. . Purvin & Gertz analyzed various sensitivity cases including a backcast from 1989 to 1998 and concluded that in all cases we can comfortably meet our debt service obligations. The Independent Engineer's Report annexed to this prospectus presents the backcast case from 1989 to 1996 because the senior debt has a term of eight years after start-up. . The PMI surplus reserve account provides liquidity during low coker margin periods, which is reflected in the backcast case with a minimum debt service coverage ratio of almost 1.0:1.0 and an average debt service coverage ratio of almost 2.0:1.0. In 2007 where debt service shortfall amounts to $3.0 million, the PMI surplus reserve account is fully funded with $50 million. In the backcast case without our long term crude oil supply agreement in place, cash flow shortfall amounts to $5.0 million, with a debt service reserve account of $37 million and over $100 million of cash available for debt service. 57 . The PMI surplus reserve account effectively mitigates the timing issue of a delay in receiving discounts after prior period surpluses. When fully funded and combined with the debt service reserve account, these reserve accounts provide up to 1.25 years of debt service coverage for our senior debt. . The proceeds of the total financing combined with the proposed equity should be sufficient to pay our total estimated coker project cost. . If the refinery upgrade project is designed, constructed, operated and maintained as currently proposed, we should be capable of meeting or exceeding the production projections. . The basis for the estimate of our total costs of operating and maintaining our heavy oil processing facility is in accordance with standard industry practice. The operating and maintenance costs set forth in the base case projections provide sufficient funds for the operations and maintenance of our heavy oil processing facility is consistent with the operating scenarios presented. Stand-alone Case To demonstrate the robustness of the economics of our operations and to ensure that we can operate independently of Clark Refining & Marketing, Purvin & Gertz developed a stand-alone case that assumes the following: . We continue our operations while the rest of the Port Arthur refinery, other than our heavy oil processing facility and the other facilities at the refinery that we have a right to use, discontinues operations; . We use the full capacity of our heavy oil processing facility; . A third-party is operating our heavy oil processing facility; . We continue to purchase crude oil under our long term crude oil supply agreement; . A third party is marketing all intermediate and finished products from our heavy oil processing facility on our behalf; and . Our rights to possession under the facility and site lease and the ground lease remain in effect. In this regard Purvin & Gertz has concluded that: . From a technical standpoint, we could successfully continue to operate in a stand-alone mode; . The modifications necessary to achieve stand-alone operation are relatively minor and could be achieved within three months; . The intermediate and finished products produced by us during stand-alone operation should be readily marketable based on appropriate discounts for quality to spot market prices to long term off-takers since we are located in the most liquid refinery products market in the world. These discounts are applied to specified intermediate products over a 3 year period to account for the market disruption caused by introducing a large volume of intermediate products into the market; and . Even in this extremely unlikely scenario, we will be able to service our debt obligations after paying all operating expenses as evidenced by a projected minimum after tax debt service coverage ratio of 1.1:1.0 and average after tax debt service coverage ratio of 1.9:1.0. 58 CRUDE OIL AND REFINED PRODUCT MARKET REPORT SUMMARY Selected conclusions of Purvin & Gertz's crude oil and refined product market report are summarized below. This report is set forth in its entirety as Annex C to this prospectus. General . The overall level of crude oil prices is set by the cost of production and supply/demand pressures. If the price is too high, the supply will increase because of the economic attractiveness of developing new reserves or producing existing reserves at higher rates. At the same time, demand is decreased by use of alternative fuels such as coal, natural gas, or nuclear energy, and/or by conservation efforts. The resulting imbalance of supply versus demand forces prices back down. In the same manner, if the price is too low, demand is stimulated, alternative energy supply development is constrained, and adding new reserves becomes less economical. Ultimately, the low prices cause demand to approach capacity limits on production, and the resulting competition for supply drives prices back up. . The absolute level of crude oil prices has a very direct impact on the feasibility of the upstream business, but crude oil price differentials have a larger impact on the economics of refinery conversion projects. The heavy/light differential in this report is expressed as the differential between West Texas Intermediate and Maya. Heavy/Light Differential . The heavy/light differential is the result of a complex balance of a number of factors, such as absolute and relative demand for light and heavy products, supply of heavy sour crude oil and conversion capacity supply/demand balance. . For the period from August 1987 to December 1998, the differential averaged $5.70 per barrel based on Platt's Oilgram Price report weekly quotes. . For the period from January 1988 to March 1999, the six-month period moving average of the heavy/light differential ranged from a high of $8.90 per barrel to a low of $3.76 per barrel, heavy/light with an average of $5.83 per barrel. . Low oil prices and reduced supplies of heavy sour crude oil relative to conversion capacity have caused the differential to narrow in late 1998/early 1999. Despite these adverse conditions, the heavy/light differential averaged about $5.00 per barrel over the past six months. . Purvin & Gertz expects the heavy/light differential to widen from 2000 to 2005, and then remain relatively stable for the remainder of the forecast period. The differential will widen due to a number of factors, such as: . a rise in the price of crude oil. All other things being equal, when the price of crude oil rises the heavy/light differential will tend to widen; . a resurgence of strong product demand in Asia, filling conversion capacity; and . an increase in the rate of development of heavy sour crude oil reserves in Mexico, Venezuela, and Canada will rapidly increase overall heavy feedstock availability and overwhelm conversion capacity. . The heavy/light differential over the 2000 to 2020 time period is forecast to average $6.51 per barrel in real terms and $8.18 per barrel in nominal terms. While there can be considerable volatility in the heavy/light differential, the market fundamentals suggest a widening heavy/light differential, which will be beneficial to us. 59 Heavy Crude Oil Availability . Purvin & Gertz expects adequate supplies of heavy sour crude oil to be available to us throughout the forecast period, given that heavy sour crude oil production is concentrated in the Western Hemisphere and expects production to increase substantially over the life of the refinery upgrade project. . Our heavy oil processing facility has been designed to process Maya produced by PEMEX. Purvin & Gertz expects Maya to be abundant given PEMEX's reserves, production levels and plans to expand production. . If the Maya is diverted from us, there are alternative supplies. Although most of the other heavy sour crude oil supplies are generally heavier than Maya, there are still heavy sour crude oils that could be used effectively in the new coker unit. . contracts for Venezuela heavy sour crude oil could probably be obtained since Venezuela plans to significantly increase its supply of heavy sour crude oil after 2000. . contracts for neutral zone crude oil could probably be obtained since the producers Saudi Arabia and Kuwait are having difficulty placing their growing supplies. . The risk of diversion of the Maya contracted to be used in the Port Arthur refinery is minimal for the following reasons: . a program to significantly expand production of Maya is currently underway and the extra supply will be difficult to place in the market due to the limited capacity of complex refineries required to process it; . the netback for heavy sour crude oil shipments to Europe or Asia is low related to U.S. Gulf Coast deliveries; and . heavy sour crude oil is run in complex high conversion refineries and the highest concentration of this type of refinery is found in the U.S. Gulf Coast. . The demand for heavy sour crude oil outside the United States is small and relates primarily to asphalt manufacture, Purvin & Gertz does not expect this to change during the forecast period. . About 75% of the refinery capacity in the U.S. East Coast, Midwest and Southwest is designed for light sweet and light sour crude oil. The light sweet refineries can not run heavy, high sulfur crude oil like Maya due to metallurgy and product specifications. The light sour refineries already run as heavy a mix of crude oil as is practical. . A heavy sour crude oil producer with an equity position in a refinery will choose to run its own crude oil rather than purchasing from others such as Mexico. PDVSA, the Venezuelan national oil company, has equity ownership of over 900,000 barrels per day of refining capacity in the United States which equals about 30% of the total heavy oil refinery capacity in the U.S. East Coast, Midwest and Southwest, and is following an aggressive strategy to secure markets for its heavy sour crude oil in competition with Mexico. . Although Mexico could decide to participate in heavy sour crude oil export cutbacks, the cutbacks are not likely to be large and would be prorated over all of its customers. Recently announced cutbacks have been in the 100,000 to 125,000 barrels per day range or about 10% of exports. The refinery upgrade project would not be materially affected by cuts of this magnitude. Product Demand . Product demand growth varies from year to year but generally averages less than 2% annually. Gasoline growth is the key to overall product growth since it accounts for 40% to 50% of the total. Jet fuel is the fastest growing product but total demand is relatively small. 60 Refinery Margins . Purvin & Gertz expects refinery margins for heavy sour crude oil processors to be significantly higher than for light sweet crude oil refineries. The refinery upgrade project will move the Port Arthur refinery into the top tier of Gulf Coast refineries. 61 SECURITY OWNERSHIP OF OWNERS Port Arthur Finance All of the outstanding capital stock of Port Arthur Finance is owned by Port Arthur Coker Company.

Port Arthur Finance is a wholly owned subsidiary of Port Arthur Coker Company whose purpose is to facilitate the financing activities of Port Arthur Coker Company. Under an agency agreement with, and an intercompany note from, Port Arthur Coker Company, Port Arthur Finance issued the outstanding notes and borrowed monies under our bank credit facilities on behalf of Port Arthur Coker Company and transferred the proceeds of the issuance of the outstanding notes and is obligated to transfer borrowings under our bank credit facilities to Port Arthur Coker Company. Port Arthur Coker Company is owned 1% by our sole general partner, Sabine River, and 99% by our sole limited partner, Neches River, a wholly owned subsidiary of Sabine River. Both Sabine River and Neches River were formed specifically for the purpose of holding our partnership interests. Occidental and Clark Refining Holdings own 10% and 90%, respectively, of Sabine River. As of February 29, 2000, Clark Refining Holdings was owned indirectly through subsidiaries, by Blackstone through an approximately 78.8% voting interest, which represents a 75.6% economic interest, and by Occidental through an approximately 19.9% voting interest, which represents a 23.1% economic interest. Sabine River Stockholders' Agreement Clark Refining Holdings and Occidental have entered into a stockholders' agreement. This agreement restricts the ownership and transfer of shares of Sabine River and provides a right of first refusal for the benefit of Clark Refining Holdings in the event that Occidental wishes to transfer its shares of Sabine River. The Sabine River stockholders' agreement also provides Occidental with the right to designate one member of the Sabine River board of directors as long as Occidental maintains a specified ownership level in Sabine River. The Sabine River stockholders' agreement grants additional rights to Occidental, including rights for Occidental to participate on an equal and ratable basis in the case of transfers of shares of Sabine River by Clark Refining Holdings. In addition, it provides Clark Refining Holdings with the right to require Occidental to sell its shares, on the same terms and conditions as Clark Refining Holdings, in the case of a sale by Clark Refining Holdings of all of its shares in Sabine River. The Sabine River stockholders' agreement provides that, if the board of directors of Sabine River determines, upon advice of its counsel, that it is no longer necessary for us, Sabine River and Neches River to be bankruptcy remote, Occidental may elect to exchange or may be required to exchange shares of common stock of Sabine River it owns for Class F Common Stock, par value $.01 per share, of Clark Refining Holdings. Transaction Fee When we issued the outstanding notes, we used a portion of the proceeds of our senior debt and equity contributions to pay Clark Refining Holdings approximately $8 million for services provided to us by Blackstone Management Partners III L.L.C. in connection with the raising of equity for and structuring of our coker project, and Clark Refining Holdings will pay such fee to Blackstone Management Partners III L.L.C. at such time and in such manner as they may agree. Transfer Restrictions Agreement We, Sabine River, Neches River, Clark Refining Holdings and Blackstone have agreed with the agent for the bank lenders, the agent for oil payment insurers and the indenture trustee, that none of us, Sabine River, Neches River, Clark Refining Holdings or Blackstone will effect, or permit any affiliate to effect, any transfer of such party's direct or indirect interest, if any, in us, Clark Refining & Marketing or the Port Arthur refinery except in limited situations. These restrictions are described in greater detail under the caption "Description of Our Principal Financing Documents--Transfer Restrictions Agreement" in this prospectus. 63 Our Relationship with Clark Refining & Marketing We are an affiliate of Clark Refining & Marketing because our parent company, Clark Refining Holdings, owns 100% of the capital stock of Clark USA, which in turn owns 100% of the capital stock of Clark Refining & Marketing. Clark Refining & Marketing formally initiated the refinery upgrade project in April 1998 after entering into the long term crude oil supply agreement with P.M.I. Comercio Internacional. Construction commenced in September 1998. When we issued the outstanding notes, we acquired the work in progress on our coker project for $157.1 million. We also paid Clark Refining & Marketing approximately $2 million for the assumption of the long term crude oil supply agreement, transfer of employees and its reduction of the permissible emissions levels under one of its air emissions permits in order to allow us to obtain our air permit. During the operating period, Clark Refining & Marketing will be obligated to accept and pay for all our products that we tender for delivery under the product purchase agreement. Clark Refining & Marketing will also provide operations and maintenance services and will supply required feedstocks for the operation of our heavy oil processing facility under the services and supply agreement. We are leasing the site of our coker project from Clark Refining & Marketing on a long term basis and have prepaid the entire rental amount of $25,000. We are also leasing some ancillary units and equipment and have obtained some related easements from Clark Refining & Marketing, for which we will pay them a quarterly rent and a monthly operating fee subject to some adjustments under the facility and site lease beginning at start-up of our heavy oil processing facility. Under this lease, Clark Refining & Marketing is also obligated to undertake modifications and additions to the equipment we are leasing. The terms of the agreements referred to in this paragraph are described under the caption "Description of Our Principal Project Documents." In the opinion of Purvin & Gertz, the terms of each of the product purchase agreement, the services and supply agreement, the ground lease and the facility and site lease are as favorable to Clark Refining & Marketing and to Port Arthur Coker Company, in all material respects, as terms that would be obtainable at this time for a comparable transaction or series of similar transactions in arm's length dealings with a person who is not an affiliate. In the opinion of Purvin & Gertz, payments to be made by Clark Refining & Marketing to us under the product purchase agreement and the services and supply agreement are fair consideration for the products acquired or services received. In the opinion of Purvin & Gertz, the consideration we paid Clark Refining & Marketing for our assumption of the long term crude oil supply agreement, our acquisition of work in progress under the construction contract and Clark Refining & Marketing's reduction of the permissible emissions levels under one of its air emissions permits in order to allow us to obtain our air permit is equal to the fair market value of these assets. According to Purvin & Gertz, Clark Refining & Marketing the rental payments under both the ground lease and the facility and site lease are equal to the fair market value rental payments of the property leased. Tax Sharing Agreement Sabine River and Neches River will file a consolidated U.S. federal income tax return together with Clark Refining Holdings and its other consolidated subsidiaries. Sabine River and Neches River have entered into a tax sharing agreement with Clark Refining Holdings and the other members of its consolidated group pursuant to which they have each agreed to pay to Clark Refining Holdings their respective share of the Clark Refining Holdings consolidated group's federal income tax liability, which will be determined on a separate return basis. Similar provisions also will apply for any state or local jurisdictions in which we file on a consolidated, combined or unitary basis together with Clark Refining Holdings or any other member of the Clark Refining Holdings' group. Clark Refining Holdings will continue to have all the rights of a parent of a consolidated group and similar rights provided for by applicable state and local law, will be the sole and exclusive agent for Sabine River and 64 Neches River in any and all matters relating to their consolidated, combined or unitary income or franchise tax liabilities. In addition, it will have sole and exclusive responsibility for the preparation and filing of consolidated federal income tax returns and will have the power, in its sole discretion, to contest or comprise any asserted tax adjustment or deficiency and to file, litigate or compromise any claim for refund on our behalf related to such return. During the period in which Sabine River and Neches River are included in the Clark Refining Holdings' consolidated group, Sabine River and Neches River could be liable in the event that any federal tax liability is incurred, but not discharged, by any other member of the Clark Refining Holdings' consolidated group. 65 PRINCIPAL PROJECT PARTICIPANTS Except in the case of Blackstone and Clark Refining & Marketing, the following information is based solely on and derived solely from publicly available documents which such entities filed with the Securities and Exchange Commission, such as their annual reports on Form 10-K and quarterly reports on Form 10-Q and, in the case of PEMEX, its annual report on Form 20-F.

PEMEX and P.M.I. Comercio Internacional PEMEX is the largest company in Mexico and one of the largest in the world. Since 1938, Mexican federal laws and regulations have entrusted PEMEX with the central planning and management of Mexico's petroleum industry. According to Petroleum Intelligence Weekly, December 14, 1998, PEMEX is the sixth largest oil and gas company in the world and the second largest in the Americas, accounting for nearly 5% of the world's crude oil and condensates production in 1997. In 1998, PEMEX, through P.M.I. Comercio Internacional, sold 1,712 thousand barrels per day of crude oil. PEMEX is a supplier of crude oil to the United States. P.M.I. Comercio Internacional, P.M.I. Trading Ltd. and their affiliates provide PEMEX and a number of independent customers with international trading, distribution and related services. P.M.I. Comercio Internacional and P.M.I. Trading Ltd. sell, buy and transport crude oil, refined products and petrochemicals in world markets. The trading volume of sales and imports of P.M.I. Comercio Internacional, P.M.I. Trading Ltd. and their affiliates totaled $9.0 billion in 1998, including $6.4 billion in crude oil sales. P.M.I. Comercio Internacional has entered into several long term crude oil supply agreements, including its long term crude oil supply agreement with us, pursuant to which the purchasers have agreed to undertake 67 projects to expand the capacity of their respective refineries to upgrade residue from Maya. These long term crude oil supply agreements further PEMEX's strategy to support the export value of Maya in relation to the value of other grades of crude oil by creating incentives for refiners to invest in new high- conversion refineries that will be capable of upgrading the relatively large portion of residue produced from processing Maya in less efficient refining complex configurations. Based on its annual report on Form 20-F filed with the Commission, as of December 31, 1998, as based on an established exchange rate for accounting purposes of Ps. 9.8650 = U.S.$1.00 at December 31, 1998, PEMEX had total assets of $42,896 million with equity of $17,599 million, both calculated in accordance with Mexican generally accepted accounting principles; the amount of PEMEX's equity calculated in accordance with U.S. generally accepted accounting principles as of December 31, 1998 was approximately $3,170 million. For the fiscal year ended December 31, 1998, PEMEX had total revenues of $26,939 million and net losses of $1,028 million, both calculated in accordance with Mexican generally accepted accounting principles; the amount of PEMEX's net losses for fiscal year ended December 31, 1998 calculated in accordance with U.S. generally accepted accounting principles was approximately $2,623 million. According to its annual report on Form 20-F filed with the Commission, as of December 31, 1998, PEMEX had proved developed reserves of 12,059 million barrels of crude oil and natural gas liquids, determined under the Society of Petroleum Engineers' and World Petroleum Congress' definitions. P.M.I. Comercio Internacional is not subject to the informational requirements under the Securities Exchange Act of 1934. The obligations of P.M.I. Comercio Internacional under our long term crude oil supply agreement are guaranteed by PEMEX. You should refer to PEMEX's publicly available documents, including its Form 20-F, for further information as to its results of operations and financial condition in evaluating the long term crude oil supply agreement.

A copy of each of these agreements has been filed as an exhibit to the registration statement of which this prospectus is a part. Unless otherwise stated, any reference in this prospectus to any agreement means such agreement and all schedules, exhibits and attachments to such agreements, as amended, supplemented or otherwise modified in effect as of the date hereof. Long Term Crude Oil Supply Agreement Clark Refining & Marketing entered into a long term crude oil supply agreement with P.M.I. Comercio Internacional in March 1998, which was amended prior to the issuance of the outstanding notes. Simultaneously with the issuance of the outstanding notes, all the rights and obligations of Clark Refining & Marketing under this long term crude oil supply agreement, including the obligation to undertake the refinery upgrade project, were assigned to Port Arthur Coker Company. In March 1998 PEMEX entered into a performance guarantee for the benefit of Clark Refining & Marketing or any assignee thereof under the long term crude oil supply agreement. Under such performance guarantee, PEMEX has unconditionally and irrevocably guaranteed the obligations of P.M.I. Comercio Internacional under the long term crude oil supply agreement. Purchase and Sale of Maya We are obligated to buy Maya from P.M.I. Comercio Internacional, and P.M.I. Comercio Internacional is obligated to sell us Maya. All Maya bought and sold under our long term crude oil supply agreement is solely for processing by us at the Port Arthur refinery. Under the long term crude oil supply agreement, the purchase and acceptance of delivered Maya is referred to as "lifting." These purchase and sale obligations are determined differently in a start-up period, a guarantee period and a phase out period. During these periods the quantity of Maya available to us is described below. Quantity of Maya Available to Us Start-Up Period. The start-up period is the period beginning the first day of the month in which we expect to first introduce feedstock into the new delayed coking unit and ending on the last day of the month in which completion of the refinery upgrade project is achieved as described below under "--The Refinery Upgrade Project--Obligation to Complete the Refinery Upgrade Project." During the start-up period, the quantity available is the amount of heavy sour crude oil that we determine we need for start-up and operation of our new delayed coking unit and our other facilities at the Port Arthur refinery less the "current capacity decrease" which is 23,553 barrels per stream day. The current capacity decrease represents the decrease in the amount of heavy sour crude oil that will be processed through the cokers in service at the time the long term crude oil supply agreement was signed. The determining periods used for comparison are March 1997 through December 1997 and the period beginning with the first month of the start-up period. Guarantee Period. The guarantee period begins on the earliest date to occur of the following and ends eight years thereafter: . the first day following the start-up period; . the scheduled completion date of January 2001, as such date may be extended as described below under "--The Refinery Upgrade Project-- Obligation to Complete the Refinery Upgrade Project"; and . the guarantee date of July 2001. The July 2001 guarantee date can be extended for specified events of force majeure or other acts or events that are beyond our reasonable control, not the result of our fault or negligence, and that we have not been able to overcome by exercising reasonable efforts, including spending funds. Our ability to extend such date due to reason of force majeure, however, is limited to a total of 365 days. 71 During the guarantee period, the formula used to determine the quantity of Maya available to us is as follows: (1) the operating capacity, multiplied by the "coker fraction" of 0.879, and divided by 0.366 minus (2) 23,553. Operating capacity is reset every six months and is the average daily volume of feedstocks processed through the new delayed coking unit during the preceding six months as stated in an officer's certificate from us. The coker fraction represents the percentage of the design capacity of our new coking unit designated for processing feedstocks from heavy crude oil. If during the guarantee period our requirements for heavy sour crude oil for processing at the Port Arthur refinery through the new delayed coking unit exceed the sum of (1) the quantity as determined in the previous paragraph plus (2) 23,553, then we may notify P.M.I. Comercio Internacional of the excess and our proposed lifting program for the month. Thereafter, the quantity of Maya available will be the greater of the quantity for the first month following such notice and the quantity as determined according to the previous paragraph. Extension of Guarantee Period. If an event of force majeure affecting the delivery, lifting or processing of Maya results in a curtailment of processing at the Port Arthur refinery of more than 25% of the amount of Maya available on average over any period of 15 or more consecutive days during the guarantee period, then the guarantee period will be extended by the number of days necessary for the Port Arthur refinery to process the quantity of Maya not processed due to such curtailment. If such event of force majeure is a governmental force majeure, as described below under "--Force Majeure--Purchase and Sale Related" and no part of the reduction of Maya to be sold and delivered to us is not applied first to reduce quantities of Maya under other crude oil supply agreements with us or any of our affiliates, then the 25% threshold described in the preceding sentence will not be a condition to the extension of the guarantee period. The aggregate period of all extensions described in this paragraph cannot exceed 270 days in respect of events of force majeure affecting the production or delivery of Maya by P.M.I. Comercio Internacional or the loading terminal facilities, and 365 days in respect of events of force majeure affecting the lifting, transportation, storage or processing of Maya by us. Phase Out Period. After the guarantee period, the quantity of Maya available will be the amount available in the final month of the guarantee period, as such amount may be phased out. After the guarantee period, each party has the option of permanently reducing the amount of Maya available in any month under the long term crude oil supply agreement upon at least three months prior notice to the other party. The monthly amount available under the long term crude oil supply agreement, however, may not be reduced in any three-month period by more than 25% of the amount available for the last month of the guarantee period. Moreover, the amount available in any month may not be reduced to less than 25% of the amount available for the last month of the guarantee period while any credit or premium remains to be applied to purchases of Maya due to a shortfall or surplus in differentials described below under "--Differential Formula and Guarantee." Remedies for Underlifting If we lift less than the amount of Maya available in any month, we are obligated to pay to P.M.I. Comercio Internacional 15% of the regular price, which is described below under "--Price of Oil," multiplied by the number of barrels of Maya "underlifted" that month. We, however, will not be liable for underlifting to the extent that underlifting of the available amount in any month results from any of the following: . operational inability of the Port Arthur refinery to process such amount; . demonstrated operational reasons concerning loading terminals or tankers, if the underlifted amount does not exceed 10% of such amount; . our remedial work or an annual turnaround, if we give P.M.I. Comercio Internacional the required notice; . our previous lifting of an amount greater than the available amount in anticipation of the weather interrupting the supply; 72 . force majeure as described below under "--Force Majeure--Purchase and Sale Related"; or . underdelivery by P.M.I. Comercio Internacional or our actions in response to an underdelivery by P.M.I. Comercio Internacional. P.M.I. Comercio Internacional may terminate the long term crude oil supply agreement because we underlifted only if we underlifted because we purchased oil in substitution of Maya or because of our failure to pay the amount due for underlifting. We are liable to P.M.I. Comercio Internacional for any resulting damages due to such termination subject to the limitations on liability described below. If we suspend or reduce the amounts that we lift, P.M.I. Comercio Internacional will not be required to resume delivery of such amount for three months or the period of suspension, whichever is shorter. Underdelivery by P.M.I Comercio Internacional P.M.I. Comercio Internacional is required to maintain the contractual right to buy Maya from Pemex Exploracion y Produccion for sale to us and the right to use specified loading terminals for delivering Maya to us. If P.M.I. Comercio Internacional suspends or reduces its deliveries of Maya, we are not obligated to resume lifting of such underdelivered amount for three months or the period of suspension or reduction, whichever is shorter. Price of Oil The price of Maya supplied to us will either be the regular price subject to adjustments as a result of the differential formula calculation or the price determined by the alternative pricing mechanism described below. Regular Price. The regular price per barrel in U.S. dollars is determined by a formula that is equal to: . 40% of the average of the Platt's prices for West Texas sour crude oil for a specified five-day period; plus . 40% of the average of the Platt's prices for no. 6 fuel oil having 3% sulfur content for such five-day period; plus . 10% of the average of the Platt's prices for light Louisiana sweet crude oil for such five-day period; plus . 10% of the average of the Platt's prices for Brent crude oil for such five-day period; minus . a pricing adjustment which is currently $3.50. This formula and actual dollar value of the price adjustment are subject to adjustment by P.M.I. Comercio Internacional. For West Texas sour and light Louisiana sweet crude oils, the "Platt's Price" for any day is the average of the high and low spot prices for such crude oils as quoted for that day in Platt's Crude Oil Marketwire (Spot Assessment Section). For Brent crude oil, the Platt's Price for any day is the average of the high and low spot prices for Brent crude oil as quoted in Platt's Crude Oil Marketwire (Spot Assessment Section). The quotation to be used is the Dated Brent Assessment. For no. 6 fuel oil having 3% sulfur content, the Platt's Price for any day is the average of the high and low spot prices for such fuel oil as quoted for that day in Platt's Oilgram U.S. Marketscan (U.S. Gulf Section, Waterborne Column). The five-day period used to determine the price of Maya for any delivery is (1) either the day on which the bill of lading is issued for such delivery if the loading of tankers for such delivery begins within the three-day range for the arrival of a tanker in the agreed lifting program for the relevant month, or the middle day of such three-day range if the loading of tankers begins after the last day of the three-day range plus (2) the two days before such first day and the two days after such first day, other than Saturdays, Sundays or other days when the relevant quotations do not regularly appear in the Platt's publications referred to above. 73 Alternative Pricing. If, during any six-month period when the regular price is in effect, the average volume of sales of Maya at the regular price under contracts with buyers not affiliated with P.M.I. Comercio Internacional, including us, that may be terminated by the buyers on three months notice to P.M.I. Comercio Internacional or less, is below 200,000 barrels per calendar day, or if the average number of such non-affiliated buyers of Maya was less than three per month, P.M.I. Comercio Internacional must notify us within 15 days following the end of that six-month period. Following this notice, the parties are required to meet to discuss and agree on whether an alternative pricing formula is needed and what the specifics of it should be. In deciding upon an alternative pricing formula, the parties must apply a detailed alternative pricing methodology. If the parties do not reach an agreement on an alternative pricing mechanism within 60 days following the end of the six-month period, they are required to submit the matter to arbitration. Reinstatement of Regular Price. Following the establishment of an alternative pricing mechanism, the price of Maya will return to the regular price if, during any six-month period that ends after the initial six month period that the alternative pricing mechanism is in effect, the average volume of sales of Maya at the regular price under contracts with non-affiliated buyers that may be terminated upon three months or less prior notice to P.M.I. Comercio Internacional is equal to or greater than 200,000 barrels per calendar day, and the average number of such non-affiliated buyers of Maya at the regular price is equal to or greater than three per month. Differential Formula and Guarantee The regular price of Maya which we are required to pay is adjusted subject to the gross margin support mechanism as described below. Our gross margin support mechanism, which is referred to in this summary as the "differential guarantee," is a $15 per barrel minimum average result of the formula, described in this summary as the differential formula, designed to serve as a proxy for coker gross margin. Differential Formula The "differential formula" is an amount in U.S. dollars per barrel calculated according to the following formula: . the average of the Platt's Prices for conventional 87 octane unleaded gasoline for that month multiplied by 50%; plus . the average of the Platt's Prices for 0.2% sulfur no. 2 fuel oil for that month; minus . one and a half times the average of the Platt's Prices for 3% sulfur no. 6 fuel oil for that month. The term "Platt's Prices" for any day means (1) the low spot prices for conventional 87 octane unleaded gasoline or 0.2% sulfur no. 2 fuel oil, as the case may be, as quoted for that day in Platt's Oilgram Price Report (Spot Price Assessments, U.S. Gulf Section, Pipeline Column) and converted to U.S. dollars per barrel, and (2) in the case of no. 6 fuel oil, the low spot prices in U.S. dollars per barrel for no. 6 fuel oil having 3% sulfur content as quoted for such day in Platt's Oilgram U.S. Marketscan (U.S. Gulf Section, Waterborne Column). In the event that a regular quotation for a particular product or fuel oil referred to above is suspended or interrupted for any reason in the relevant publication for fewer than 10 of the days in any month, then the days for which such quotation is suspended or interrupted are not taken into account in calculating the average of the Platt's Prices for that product or fuel oil. Moreover, that average is calculated for only the number of days in such month that quotations were not suspended or interrupted. In the event that a regular quotation for a particular product or fuel oil referred to above is suspended or interrupted for any reason in the relevant publication for 10 or more days in any month, then the parties are required to meet promptly to discuss and agree upon an appropriate alternative reference price for calculation of the differential. Alternative Differential Calculation In the event that (a) the absolute value of the arithmetic average, for the immediately preceding 24 month period, of the difference between (1) the regular price and (2) the sum of (A) 0.679 multiplied by the price of 74 no. 6 fuel oil plus (B) 0.185 multiplied by the sum of the price of conventional 87 octane unleaded gasoline and the price of 0.2% sulfur no. 2 fuel oil minus (C) 2.874, the "Maya proxy," exceeds (b) $0.50 per barrel for any month, then the price of no. 6 fuel oil to be used in calculating the Differential beginning in the month following that 24-month period will be equal to the sum of (A) 1.473 multiplied by the regular price, plus (B) 4.233, minus (C) 0.272 multiplied by the sum of the price of conventional 87 octane unleaded gasoline and the price of 0.2% sulfur no. 2 fuel oil. Each of these fuel oil and gasoline prices are to be determined according to the provisions described above under "--Differential Formula and Guarantee." Reinstatement of Differential Calculation If an alternative differential calculation becomes applicable and thereafter the absolute value of the arithmetic average, for the immediately preceding 24 month period, of the difference between the regular price and the Maya proxy is equal to or less than $0.50 per barrel, then the price of no. 6 fuel oil to be used in calculating the differential beginning in the month following such 24- month period is as determined according to the formula used for calculating the differential. Determination of Surpluses and Shortfalls. A "monthly shortfall" for any month all or part of which is within the guarantee period, is the amount equal to the product of (1) $15.00 less the differential for that month, if greater than zero, multiplied by (2) 36.6% of the monthly quantity of Maya delivered to us by P.M.I. Comercio Internacional. If P.M.I. Comercio Internacional underdelivers in any month, however, it will be deemed to have delivered us the entire amount of Maya available in such month less any deliveries excused for force majeure. A "monthly surplus" for any month all or part of which is within the guarantee period, is the amount equal to the product of (1) the differential for that month less $15.00, if greater than zero, multiplied by (2) 36.6% of the quantity delivered to us by P.M.I. Comercio Internacional in that month, as prorated for any month which is only partly within the guarantee period. In the event, however, that completion of the refinery upgrade project does not occur by the guarantee date in July 2001, as such date may be extended by reason of force majeure, for the purpose of determining any monthly surplus P.M.I. Comercio Internacional will be deemed to have delivered the entire quantity of Maya available for such month as if completion had been achieved. In addition, in the event that we underlift Maya on or after the completion of the refinery upgrade project then, for the purpose of determining any monthly surplus, P.M.I. Comercio Internacional will be deemed to have delivered the entire quantity of Maya available to us in such month less any volume that we have been excused from underlifting pursuant the provisions described under "-- Remedies for Underlifting" above. A "quarterly shortfall" with respect to any calendar quarter, is the amount, if any, by which (1) the sum of the monthly shortfalls in such calendar quarter exceeds (2) the sum of the monthly surpluses in such calendar quarter. A "quarterly surplus" with respect to any calendar quarter, is the amount, if any, by which (1) the sum of the monthly surpluses in such calendar quarter exceeds (2) the sum of the monthly shortfalls in such calendar quarter. Credit Interest. "Credit interest" with respect to any calendar quarter is the amount of interest calculated for such calendar quarter (other than any period during which processing at the Port Arthur refinery is curtailed due to a force majeure event that extends the guarantee period) at LIBOR plus 1% on the sum, if greater than zero, of: . the aggregate of all credits calculated pursuant to the provisions described under "--Shortfall in Differentials" below for all prior calendar quarters; plus . the aggregate amount of credit interest for all prior calendar quarters; minus . the aggregate of all premiums calculated pursuant to the provisions described under "--Surplus in Differentials" below for all prior calendar quarters. 75 Shortfall in Differentials If at the end of any calendar quarter, all or part of which is within the guarantee period, there is a quarterly shortfall, we will receive a credit against the purchase price of Maya delivered in the succeeding calendar quarter. The credit will be equal to the sum, if greater than zero, of such quarterly shortfall minus the amount, if any, by which the aggregate of all quarterly surpluses for prior calendar quarters exceeds the aggregate of all quarterly shortfalls and credit interest for prior calendar quarters. Formulas for calculating these amounts are described above under "--Reinstatement of Differential Calculation--Determination of Surpluses and Shortfalls" and "-- Credit Interest." The sum of such credit plus any credit carryforward from such calendar quarter minus any premium carryforward from such calendar quarter will be applied at the rate of $5.00 per barrel of Maya beginning with the first barrel delivered in such succeeding calendar quarter. The "premium carryforward" is the amount that has not been applied to Maya delivered in such succeeding calendar quarter by the end of the calendar quarter plus interest at LIBOR plus 1% calculated for the period of such succeeding calendar quarter. The maximum credit to be applied in such succeeding calendar quarter is $30 million. If the sum is less than zero, we must pay a premium on the purchase price of Maya delivered in the succeeding calendar quarter. The premium is equal to the positive value of such sum applied at the rate of $5.00 per barrel of Maya beginning with the first barrel delivered in such succeeding calendar quarter. The maximum premium to be applied in such succeeding calendar quarter is $20 million. If, by the end of any such succeeding calendar quarter there remains an amount which has not been applied as outlined in the preceding paragraph or in provisions described below under "--Surplus in Differentials," to Maya delivered in such succeeding calendar quarter, then such remaining amounts, together with interest at LIBOR plus 1% calculated for the period of such succeeding calendar quarter, will constitute a credit carryforward from such succeeding calendar quarter. If, by the end of any calendar quarter, all or part of which is within the guarantee period, both the quarterly surplus and the quarterly shortfall equal zero, and the sum of any credit carryforward minus any premium carryforward is greater than zero, then we will receive a credit equal to such sum. The credit is applied at the rate of $5.00 per barrel of Maya, beginning with the first barrel of Maya delivered in such succeeding calendar quarter. The maximum aggregate amount that may be applied is $30 million. Surplus in Differentials If, by the end of any calendar quarter, all or part of which is within the guarantee period, the sum of monthly surpluses, exceeds the sum of monthly shortfalls, there is a "quarterly surplus" in such calendar quarter and we are required to pay a premium on the purchase price of Maya delivered beginning in the succeeding calendar quarter. The amount of the premium equals the lesser of (1) the amount of such quarterly surplus and (2) the amount that the aggregate of all quarterly shortfalls and credit interest for prior calendar quarters and such calendar quarter exceeds the aggregate of all quarterly surpluses for prior calendar quarters. The sum of (1) such premium, plus (2) any premium carryforward from such calendar quarter minus (3) any credit carryforward from such calendar quarter will be applied at the rate of $5.00 per barrel of Maya beginning with the first barrel delivered in such succeeding calendar quarter. Such sum may be applied up to a maximum aggregate amount in such succeeding calendar quarter of $20 million. If the sum is less than zero, we will receive a credit against the purchase price of Maya delivered in the succeeding calendar quarter. Such credit will be equal to the positive value of such sum applied at the rate of $5.00 per barrel of Maya beginning with the first barrel delivered in such succeeding calendar quarter. The maximum credit that may be applied in such succeeding calendar quarter is $30 million. If, by the end of any calendar quarter, all or part of which is within the guarantee period, both the quarterly surplus and the quarterly shortfall equal zero, and the sum of any credit carryforward minus any premium carryforward is less than zero, then we are required to pay a premium. The premium is equal to the positive value of such sum, applied at the rate of $5.00 per barrel of Maya, beginning with the first barrel of 76 Maya delivered in such succeeding calendar quarter. The premium may be applied to a maximum aggregate amount in such succeeding calendar quarter of $20 million. End of Guarantee Period The net adjustment amount, whether positive or negative existing at the end of the period during which the coker gross margin support is available will be applied over the remaining term of the agreement, after giving effect to the operation of the differential mechanism in the last period. However, the discount we receive in any quarter will not exceed $30 million and the premium we pay in any quarter will not exceed $20 million. Payment Terms We are required to make all payments to P.M.I. Comercio Internacional when due in immediately available U.S. dollars. Interest accrues daily on the amount of any overdue payment, commencing on the date that the payment was due. The rate per annum will be equal to 2% above the prime rate. We are required to make all payments due P.M.I. Comercio Internacional punctually and without set- off. Security for Payment Under specified circumstance, P.M.I. Comercio Internacional requires us to provide security for the performance of our payment obligations by means of one or more stand-by letters of credit or a financial guaranty insurance policy meeting specified requirements. Such letters of credit or financial guaranty insurance policy must always equal at least the total amount of all outstanding invoices under the long term crude oil supply agreement plus 110% of the estimated value of Maya that we have lifted but for which P.M.I. Comercio Internacional has yet to issue an invoice. We will meet this obligation by entering into the oil payment guaranty insurance policy with Winterthur. Suspension of Deliveries P.M.I. Comercio Internacional may suspend deliveries of Maya if we do not make a payment of $100,000 or more that is due P.M.I. Comercio Internacional under the long term crude oil supply agreement or any other crude oil agreement between us. P.M.I. Comercio Internacional may also suspend deliveries if we do not establish and maintain any stand-by letter of credit or financial guaranty insurance policy that we are required to maintain. If P.M.I. Comercio Internacional suspends deliveries and we subsequently make the required payment together with accrued interest then P.M.I. Comercio Internacional is required to resume deliveries but is not obligated to do so for a period of time equal to the shorter of the suspension period or three months. Termination If we or P.M.I. Comercio Internacional default under our respective purchase or sale obligations and such default continues for 60 days, the other party may terminate the long term crude oil supply agreement effective immediately upon notice. Force Majeure--Purchase and Sale Related General. Neither party is liable for any damages that arise from delays or defaults in performance of the purchase and sale or delivery term provisions of the long term crude oil supply agreement that are due to force majeure. If either of us intends to rely on an event of force majeure to suspend our performance, that party must give prompt notice of the event to the other party. Force majeure will not relieve us of our obligation to pay for all Maya delivered or any other amount that we owe to P.M.I. Comercio Internacional under the long-term crude oil supply agreement. Event of Force Majeure. Force majeure for these purposes includes any act or event that prevents or delays either party from performing its obligations if and to the extent that the act or event is beyond the party's control and is not due to its fault or negligence, and to the extent that the party was not able to overcome the consequence of by commercially reasonable efforts, including spending funds. 77 . acts of God or of the public enemy, floods, fire, electrical shortages or blackouts; . hostilities, war, blockades or riots; . strikes or other labor disturbances that are not the result of breach of a labor contract by the affected party; . earthquakes, tides, storms or bad weather at the loading terminal; . breakdown or injury to producing or delivering facilities in Mexico or to receiving or processing facilities at the Port Arthur refinery; . interruption, decline or shortage of P.M.I. Comercio Internacional's supply of Maya available for export from Mexico, including shortage due to increased domestic demand; . laws, change in laws, decrees, regulations, orders or other directives or actions of either general or particular application, other than as may be directed to aspects of the long term crude oil supply agreement not common to long term crude oil supply agreements generally, of the government of Mexico or the government of the United States of America or any agency thereof that does not include P.M.I. Comercio Internacional, Pemex Exploracion y Produccion, or any of P.M.I. Comercio Internacional's other affiliates; and . ""governmental force majeure," which means the reduction of P.M.I. Comercio Internacional's Maya deliveries under its contractual commitments to export customers in general as a result of a direction from the federal government of Mexico to curtail crude oil exports despite the availability of Maya for export. Apportionment. If P.M.I. Comercio Internacional does not have enough Maya available to export for sale to us and its other customers because of force majeure, it may not reduce the quantity of Maya that it sells to us by more than the percentage that it reduces the total amount of its sales of Maya to other export customers under agreements to supply 50,000 barrels per calendar day or more of Maya or to its other customers in general if the agreements account for less than 20% of its exports of Maya. P.M.I. Comercio Internacional is not required to buy crude oil from another party to sell to us because of an event of force majeure. If, however, the event is a governmental force majeure, as described above, then the amount by which it would otherwise reduce the quantity of Maya to be sold to us shall first be applied to reduce quantities of Maya scheduled for sale and delivery to the Port Arthur refinery under any other crude oil supply agreement with us or any of our affiliates. The Refinery Upgrade Project Obligation to Complete the Refinery Upgrade Project Under the long term crude oil supply agreement, we are obligated to complete the refinery upgrade project by the scheduled completion date of January 2001. If, however, the refinery upgrade project is not complete by such scheduled completion date, we may make payments to P.M.I. Comercio Internacional to extend the scheduled completion date according to a specified formula. We expect such payments to equal approximately $400,000 per month for each of the first six months we choose to extend the scheduled completion date and approximately $200,000 per month for each month beyond six months that we choose to extend the scheduled completion date. Such date is subject to extension for specified events of force majeure or other events beyond our reasonable control in the same manner as extension of the guarantee date up to a total of 365 days. For purposes of the long term crude oil supply agreement and this summary of such agreement, completion of the refinery upgrade project occurs when: . all significant aspects of the refinery upgrade project are mechanically complete and substantially conform to their design plans and specifications; . the commission testing of processing units in the refinery upgrade project is complete; and 78 . the Port Arthur refinery and the new delayed coking unit are able to process at least 80% of their design capacities on average over a 30 day consecutive period, or, we commence operation of the new delayed coking unit and other equipment integrated into the Port Arthur refinery that we own and we and Foster Wheeler USA stop making efforts to achieve those average processing capacities. If we fail to extend the scheduled completion date, P.M.I. Comercio Internacional has the right to terminate the long term crude oil supply agreement. In such case, we are liable to P.M.I. Comercio Internacional for their resulting damages, subject to our termination rights described in the following paragraph and the limitations on liability described below. Our Right to Terminate the Long Term Crude Oil Supply Agreement Prior to the first day of the month in which we expect to first introduce feed into our new delayed coking unit, we may terminate the long term crude oil supply agreement under the following circumstances: . If we abandon the refinery upgrade project or decide to continue the refinery upgrade project without the benefit of the long term crude oil supply agreement or an alternative supply arrangement, we may terminate the long term crude oil supply agreement by first giving notice to P.M.I. Comercio Internacional and within fifteen days paying them a termination payment. For the purposes of the long-term crude oil supply agreement an alternative supply arrangement means any contract, agreement or arrangement, other than the long term crude oil supply agreement, pursuant to which we, any purchaser of the Port Arthur refinery or any part thereof, or any affiliate of any of us has the right to purchase, on a long term basis, any substantial portion of the Port Arthur refinery's requirements for heavy sour crude oil attributable to the refinery upgrade project or to any similar upgrade project designed to increase significantly the Port Arthur refinery's capacity to process heavy sour crude oil having characteristics similar to Maya; and . We may also terminate the long term crude oil supply agreement without abandoning the refinery upgrade project by entering into an alternative supply arrangement and paying P.M.I. Comercio Internacional the termination payment described above plus an additional fee equal to their damages resulting from a breach of the long term crude oil supply agreement in its entirety. Limitation of Liability Neither party is liable for any consequential or punitive damages of any kind arising out of or in any way connected with the performance, of or failure to perform, the long term crude oil supply agreement including, but not limited to, losses or damages resulting from shutdown of plants or inability to perform sales or any other contracts arising out of or in connection with the performance or nonperformance of the long term crude oil supply agreement. This liability limitation is not meant to limit either party's right to recover its incidental damages or damages associated with the mechanism for adjustment to our payment obligations described under "--Differential Formula and Guarantee" above. Miscellaneous Provisions Dispute Resolution If a dispute arises from the long term crude oil supply agreement, the parties are to seek to settle the dispute through good faith negotiation between senior executives. If after 60 days the dispute is not settled, either party may initiate arbitration of the dispute. All disputes arising from the long term crude oil supply agreement will be settled finally by arbitration under the Rules of Arbitration and Conciliation of the International Chamber of Commerce. The arbitration will occur in New York, in English and the substantive law will be that of the State of New York. Governing Law The long term crude oil supply agreement is governed by and interpreted in accordance with the laws of the State of New York. The United Nations Convention on the International Sale of Goods will not apply to the long term crude oil supply agreement. 79 Language English is the language of the long term crude oil supply agreement and controls over any Spanish language translations. Entire Agreement The long term crude oil supply agreement supersedes all prior agreements between us and our affiliates and P.M.I. Comercio Internacional and its affiliates except the crude oil sales agreement entered into on January 1, 1990, between P.M.I. Comercio Internacional and Clark Oil & Refining Corporation, the predecessor company to Clark Refining & Marketing, as amended and assigned and which remains in force. Construction Contract We entered into a contract for engineering, procurement and construction services with Foster Wheeler USA in July 1999. This construction contract obligates Foster Wheeler USA to engineer, design, construct, erect, install and test our coker project, to provide procurement services and training support for us and to oversee start-up, operation and performance testing of our coker project. Effective Date and Commencement of Work Foster Wheeler USA did not commence work under the construction contract and we had no obligation with respect to the construction contract until August 1999 when: . all other documents related to our coker project had been executed and delivered by all parties; . the initial issuance of outstanding notes had occurred and we had sufficient funds available to acquire the work in progress related to our coker project from Clark Refining & Marketing; and . we delivered a notice to proceed to Foster Wheeler USA. Contractor's Responsibilities Scope of Work The responsibilities of Foster Wheeler USA under the construction contract include, among other things: . providing all engineering and design services necessary for the completion of our coker project; . procuring all labor, materials, equipment, supplies and other services necessary for completion of our coker project except supplies to be provided by us; . providing all construction, erection and installation services necessary for the completion of our coker project except services to be provided by us; . obtaining all permits necessary for the construction, except permits provided by us; . performing all cleanup, removal and disposition services with respect to hazardous waste and other debris resulting from its work at the construction site; . initiating, maintaining and supervising all safety precautions and programs in connection with performance of the construction contract; . cooperating with, and overseeing, our start-up of our new processing units and the operation of our new processing units during start-up and performance testing; . carrying out all tests and inspections required under the construction contract; 80 . preparing initial operational guidelines for our new processing units, cooperating with us in preparation of initial drafts of operation manuals for our units and ensuring the proper content of final operating manuals; . providing maintenance and instruction manuals and mechanical catalogs for our new processing units; . providing lists of recommended spare parts for our new processing units and cooperating with us and Purvin & Gertz in its role as independent engineer to ensure procurement of spare parts; and . fulfilling Purvin & Gertz's requests for information. Subcontracting Foster Wheeler USA may not subcontract any portion of the work to be performed under the construction contract without our consent. Foster Wheeler USA will remain responsible for all its obligations under the construction contract regardless of its reliance on subcontractors. Foster Wheeler USA will ensure that major subcontract agreements provide that, in the event Foster Wheeler USA is terminated as contractor, (1) the subcontractor will continue performance if requested by us and (2) the subcontract may be assigned to us or to the holders of our senior debt for security on the same terms as the original agreement. Assumption of Risk Prior to execution of the construction contract, Foster Wheeler USA was performing portions of the work at the construction site pursuant to an interim reimbursable contract with Clark Refining & Marketing. Foster Wheeler USA has acknowledged, among other things, that it has examined the construction site and made independent inquiries into the availability of materials, labor and other supplies and is satisfied that each is sufficient for performance of its obligations. Foster Wheeler USA has also acknowledged that we and Clark Refining & Marketing have provided them other information with respect to existing subsurface conditions and facilities at the construction site and has agreed that the construction site is satisfactory for performance of the construction contract. Accordingly, Foster Wheeler USA has assumed price and schedule risks associated with construction site conditions, except risks associated with hazardous waste existing at the construction site on the execution date of the construction contract other than hazardous waste that is known to us that we have disclosed to Foster Wheeler USA. Contract Amount and Payment Fixed Price As full compensation for performance of its obligations under the construction contract, we will pay Foster Wheeler USA a fixed price of $544 million. The fixed price is subject to change based on valid change orders, as described below under "--Changes in Work." This price includes work performed under Clark Refining & Marketing's existing reimbursable contract with Foster Wheeler USA through the effective date of the construction contract. Approximately $157.1 million paid under such contract through July 1999 and related to our coker project has been credited against our fixed contract price. We are required to make payments to Foster Wheeler USA in monthly installments based on receipt and approval of invoices from Foster Wheeler USA and the achievement of specified construction milestones. Letters of Credit or other Payment Security As security for its performance under the construction contract, Foster Wheeler USA has provided us with a letter of credit on the effective date of the construction contract. Foster Wheeler USA is obligated to maintain one or more letters of credit with an aggregate amount available for drawings always equal to at least 10% of amounts actually paid by us to Foster Wheeler USA less the amount of all prior drawings other than drawings made when the rating of the issuer of the letter of credit has fallen below the required rating or final completion 81 has not occurred 30 days prior to the expiration of such letter of credit and it has not been extended or substituted. Foster Wheeler USA has the option to fulfill its letter of credit obligations, in whole or in part, by either depositing cash with us pursuant to a cash collateral agreement acceptable to us or our senior debt holders or by requesting that we withhold amounts that would otherwise be payable to them under the construction contract. The issuer of such letter of credit must meet specified standards including, among others, that it have outstanding unsecured debt rated A or better by Standard & Poor's or A2 or better by Moody's. Our Responsibilities Our responsibilities under the construction contract include, among other things: . paying installments of the fixed contract amount upon achievement of construction milestones; . providing limited construction services; . providing water and temporary utilities necessary for Foster Wheeler USA's performance of the construction contract and providing other consumables; and . operating our new processing units and other equipment during start-up and testing, including supply of necessary feedstreams and disposition of output, subject to Foster Wheeler USA's right to exercise such supervision and control as necessary for its performance of the construction contract. Independent Engineer The construction contract entitles the holders of our senior debt to retain an independent engineer, Purvin & Gertz, who will, among other things: . review and report on Foster Wheeler USA's monthly status reports; . review and monitor the performance tests and other tests and inspections performed by Foster Wheeler USA; . review and approve applications by Foster Wheeler USA for installment payments of the contract amount; . inspect Foster Wheeler USA's performance and any labor, materials and equipment furnished or used by Foster Wheeler USA; . approve use by Foster Wheeler USA of non-prototype equipment or subcontractors not on the pre-approved list of subcontractors; and . approve achievement of mechanical completion and final completion, each as described below. Mechanical Completion and Other Conditions to Performance Testing Mechanical Completion Foster Wheeler USA is obligated to achieve mechanical completion of our coker project before commencement of commissioning and start-up of our new processing units by March 2001, as such date may be extended pursuant to valid change orders. Mechanical completion of our coker project will occur when the following have been achieved: . each physically discrete unit of our coker project has been erected and has passed specified tests; . Foster Wheeler USA has completed all work under the construction contract except for minor items and inconsequential defects and deficiencies, which will be considered punch list items; . we, Foster Wheeler USA and Purvin & Gertz have agreed to a punch list and a start-up protocol; 82 . our coker project can operate safely and meets all requirements of the construction specifications necessary to begin commissioning and start-up activities; . we and Purvin & Gertz have approved a notice of mechanical completion delivered by Foster Wheeler USA; and . we have received final operating manuals and maintenance and instruction manuals from Foster Wheeler USA. The actual date of mechanical completion will be deemed to occur on one of the following dates: . on the date when all requirements for mechanical completion, as described above, have been achieved; . on the date when all requirements for mechanical completion are met except for mechanical completion of our new delayed coking unit, provided that it is mechanically complete within 14 days of the achievement of all other conditions to mechanical completion; or . on the date that is 14 days prior to the date that mechanical completion of our new delayed coking unit is achieved if mechanical completion of our new coking unit is achieved more than 14 days after the date that all other conditions to mechanical completion are achieved. Commissioning and Start-Up Once our coker project is mechanically complete, we, with the cooperation of Foster Wheeler USA and Purvin & Gertz, will conduct test runs and other start- up activities for our coker project. Foster Wheeler USA will oversee these commissioning activities and monitor them to determine whether these activities are conducted in conformance with the construction contract and the start-up protocol developed by the parties. Foster Wheeler USA must give us immediate notice if any commissioning or start-up activities are not conducted in accordance with such standards. Accordingly, Foster Wheeler USA will not have a defense to its liabilities under the construction contract based on our use of improper procedures or other occurrences during this period unless it gives us such notice. Performance Testing and Guarantees Following mechanical completion of our coker project, Foster Wheeler USA is responsible for conducting performance tests to: . demonstrate achievement of the performance guarantees of Foster Wheeler USA; . demonstrate achievement of final completion of our coker project; and . determine damages for failure to achieve such performance and completion guarantees. Guaranteed Reliability Foster Wheeler USA will conduct a reliability test to demonstrate whether during a continuous 60-day period our new processing units achieve 100% of a specified guaranteed "daily net margin" while not exceeding the guaranteed emissions and effluent limits described below. The calculation of the daily net margin is based on a specified price set for valuing feedstocks processed during reliability testing, the variable costs of processing such feedstocks and the products produced by our new units during such testing and is intended to serve as a proxy to demonstrate whether our new processing units can reliably generate expected operating margins. Substantial Reliability If a reliability test demonstrates that our new processing units have achieved 95% of the specified guaranteed daily net margin, Foster Wheeler USA will be deemed to have achieved substantial reliability. Guaranteed Capacity Foster Wheeler USA will also conduct a capacity test to demonstrate whether for a continuous uninterrupted 72 hour period each of our new processing units achieves specified guaranteed design capacities while not exceeding the guaranteed emissions and effluent limits. 83 Guaranteed Emissions and Effluent Limits For either a capacity or reliability test to be successful, Foster Wheeler USA must also demonstrate during such test that operation of our new processing units will meet specified guaranteed standards for emission of gaseous, liquid and solid pollutants which are designed to ensure compliance with our air emissions permit. Final Completion Foster Wheeler USA is obligated to achieve "final completion" of our coker project by December 2001, as such date may be extended pursuant to valid change orders. Final completion of our coker project will occur when, among other things: . mechanical completion has been achieved; . either (1) a reliability test has demonstrated that 100% of the guaranteed reliability has been achieved and the guaranteed capacities described above have been achieved or (2) Foster Wheeler USA has successfully concluded a reliability test demonstrating achievement of substantial reliability as described above and has paid us the applicable amounts described below under "--Buydown Payments for Failure to Achieve Guaranteed Reliability or Capacity"; . Foster Wheeler USA has paid us any late payments that are due to us as described below under "--Damages for Delay"; . all punch list items have been completed or the completion of such items has been temporarily waived by us, with the approval of Purvin & Gertz; and . we and Purvin & Gertz have issued a certificate approving Foster Wheeler USA's notice of final completion. Damages for Delay Delay in Achieving Mechanical Completion If Foster Wheeler USA fails to achieve mechanical completion by January 2001, as such date may be extended pursuant to valid change orders, they are obligated to pay us late payments for each day from such date until December 2001, as such date may also be extended pursuant to valid change orders. Delay in Achieving Guaranteed Reliability Without duplication of late payments for delay in achieving mechanical completion, Foster Wheeler USA is also obligated to pay us late payments for each day after January 2001, as such date may be extended pursuant to valid change orders, that it fails to demonstrate achievement of 100% of the guaranteed daily net margin. Amount of Late Payments Late payments will be calculated on a daily basis. Late payments due each day will equal one-seventh of the applicable cost factor in the following chart. After July 2001 late payments will also include a "throughput factor" intended to replace the loss of expected profits. Date Cost Factor ---- ----------- January 1, 2001 -- January 31, 2001.............................. $ 100,000 February 1, 2001 -- March 31, 2001............................... $1,146,250 April 1, 2001 -- June 30, 2001................................... $1,842,500 July 1, 2001 -- September 30, 2001............................... $1,595,000 October 1, 2001 forward.......................................... $2,750,000 84 The throughput factor will be calculated on a daily basis according to the following formula: $12.00 * (76,300 less the number of barrels of throughput processed by our new coker on that day) 76,300 barrels per day is approximately 95% of the design capacity of our new coking unit. Operating Revenue Credit Against Late Payments For each day that Foster Wheeler USA makes late payments to us, we will provide them a credit against future late payments equal to our operating revenue for such day. For this purpose our operating revenue is defined as the difference between our cash revenues and cash expenses attributable to such day. Early Completion Bonus For each day that Foster Wheeler USA achieves mechanical completion prior to the target date of November 2000 or 60 days prior to guaranteed mechanical completion, whichever is later, they will receive a bonus payment equal to one- seventh of $900,000 for each such day during September 2000 and one-seventh of $600,000 for each such day during October 2000. The total amount of all such bonuses, however, may not exceed $6 million. In no event will Foster Wheeler USA receive such bonus payments if it (1) incurs an obligation to make late payments or payments for failure to achieve its guarantees of capacity or reliability or (2) fails to achieve final completion of our coker project. Buydown Payments for Failure to Achieve Guaranteed Reliability or Capacity If Foster Wheeler USA fails to achieve 100% of the guaranteed daily net margin described above, it will be obligated to make buydown payments according to a specified formula. If Foster Wheeler USA fails to achieve 100% of the guaranteed design capacities it will be obligated to make additional buydown payments to us according to specified formulas up to a maximum amount of $2 million related to our new coking unit and up to $5 million related to our new hydrocracker. Limitations on Liability Late Payments Foster Wheeler USA's liability for failing to achieve mechanical completion by January 2001, as such date may be extended by valid change orders, or failure to achieve the guaranteed daily net margin by such date is limited to making the late payments described above. In addition, if Foster Wheeler USA demonstrates achievement of substantial reliability during a reliability test, its liability for making late payments to us will be capped at $70 million. Buydown Payments Foster Wheeler USA's liability for failing to achieve the guaranteed daily net margin, the guaranteed standards of emissions and effluent limits or the guaranteed capacities is limited to making the payments described above under "Buydown Payments for Failure to Achieve Guaranteed Reliability or Capacity." In addition, if Foster Wheeler USA demonstrates achievement of substantial reliability during a reliability test, its liability for making such payments to us will be capped at $75 million. Total Damages Foster Wheeler USA's total liability for damages arising under the construction contract is capped at 100% of our fixed contract amount. This liability cap, however, does not apply to any damages arising out of Foster Wheeler USA's indemnification obligations. Integration of Other Portions of the Refinery Upgrade Project Work by Foster Wheeler USA. Foster Wheeler USA bears the risk of successfully integrating our new units with the remainder of the Port Arthur refinery to the extent that the refinery is modified or improved 85 by the work to be performed by Foster Wheeler USA under its reimbursable contract with Clark Refining & Marketing. In the event of any defect or deficiency in such work, the obligation to correct defects or deficiencies is the responsibility of Foster Wheeler USA and Clark Refining & Marketing. Work by Us or Clark Refining & Marketing. We and Clark Refining & Marketing bear the risk of successfully integrating our new units with the remainder of the Port Arthur refinery to the extent in each case that work on units, equipment items or systems is performed by Clark Refining & Marketing or us, as the case may be.

Change in Actual Costs. If either we or Clark Refining & Marketing determine that the price for any service or supply does not reflect accurately the actual cost of providing such service or supply, then we will meet to negotiate an equitable adjustment to the pricing of such service or supply. Any such adjustments, however, may not have a material adverse effect on our ability to pay our senior debt obligations when they become due or payable and will not become effective until approved by Purvin & Gertz in its role as independent engineer. Expansion of Refinery Operations. To the extent that any expansion of operations of Clark Refining & Marketing at the Port Arthur refinery causes an increase in the pricing of utilities or waste management services to be provided to us, Clark Refining & Marketing is obligated to reduce the amount payable by us for such service so that it conforms to the pricing that would have been in effect if such expansion had not occurred. Processing of Feedstocks Owned by Clark Refining & Marketing Construction Period Prior to start-up and testing of our new processing units under our construction contract with Foster Wheeler USA, Clark Refining & Marketing has a right of first refusal which, if exercised, would require us to process crude oil owned by Clark Refining & Marketing. Clark Refining & Marketing may exercise these processing rights so long as it pays for all related operating expenses and processing does not interfere with the performance of the upgrades and improvements to such leased units, the construction of our coker project or the achievement of the performance guarantees of Foster Wheeler USA related to our coker project and will not adversely affect the reliability or the useful life of the processing units we are leasing from Clark Refining & Marketing. We are being compensated for granting these processing rights in the form of a reduction in the amount of rent that otherwise would have been payable under our facility and site lease. Start-up Period During start-up and performance testing of our coker project, Clark Refining & Marketing will not have any right to require us to process crude oil owned by Clark Refining & Marketing through our heavy oil processing facility. 94 Post-Completion Period Ancillary Equipment. After our coker project is finally complete, Clark Refining & Marketing will have a right of first refusal each calendar quarter. This right of first refusal, if exercised, would require us to process crude oil owned by Clark Refining & Marketing each day in an amount up to the portion of the actual capacity of the units in excess of either (1) the quantity of Maya available to us under the long term crude oil supply agreement on such day and the light sour crude oil necessary to process such Maya or (2) if P.M.I. Comercio Internacional has curtailed the amount of Maya available to us under our long term crude oil supply agreement, the amount of crude oil sufficient to operate our new coker unit at 80% of its actual capacity on such day. Clark Refining & Marketing will compensate us in the form of a processing fee based on the number of barrels of Clark Refining & Marketing-owned crude oil processed by us each day. The formula for calculating this fee is intended to approximate the fixed and variable costs of processing such Clark Refining & Marketing-owned crude oil through our leased units. If Clark Refining & Marketing does not exercise this right, we may sell our excess capacity to an alternative purchaser and Clark Refining & Marketing is obligated to provide such third party the services and supplies necessary to utilize such capacity. Coker. Clark Refining & Marketing will also have a right of first refusal each calendar quarter which, if exercised, would require us to process feedstocks owned by it each day in an amount up to the excess of the volume necessary to process the vacuum tower bottoms produced by the processing of our crude oil through our leased units each day. We may process these feedstocks through our delayed coking unit or, at our option, through any other appropriate equipment to which we may have access. Clark Refining & Marketing will compensate us in the form of a processing fee based on the number of barrels of Clark Refining & Marketing-owned crude oil processed by us each day. The formula for calculating this fee is intended to approximate the fixed and variable costs of processing such Clark Refining & Marketing- owned crude oil through our new delayed coking unit. If Clark Refining & Marketing does not exercise this right, we may sell such capacity to an alternative purchaser and Clark Refining & Marketing is obligated to provide such third party the services and supplies necessary to utilize such capacity. Hydrocracker. Clark Refining & Marketing will also have a right of first refusal each calendar quarter which, if exercised, would require us to process feedstocks owned by it each day in an amount up to the portion of the actual capacity of our new vacuum gas oil hydrocracker needed to process gas oil each day that exceeds the capacity necessary to process the gas oil produced by the processing of our vacuum tower bottoms through our new delayed coking unit each day. Clark Refining & Marketing will compensate us in the form of a processing fee based on the number of barrels of Clark Refining & Marketing- owned crude oil processed by us each day. The formula for calculating this fee is intended to approximate the fixed and variable costs of processing such Clark Refining & Marketing-owned crude oil through our new hydrocracker. If Clark Refining & Marketing does not exercise this right, we may sell such capacity, or portion of such capacity, to an alternative purchaser or direct Clark Refining & Marketing to ensure that such capacity, or portion of such capacity, is used to process gas oils produced by processing our crude oil through our leased units. In either case, Clark Refining & Marketing is obligated to provide us and/or such third party the services and supplies necessary to utilize such capacity. Permitted Operational Adjustments General Modifications Clark Refining & Marketing may modify the operations of our heavy oil processing facility at its discretion as long as the modification does not: . impede production of the quantity and quality specifications of products to be provided pursuant to our product purchase agreement with them; . cause an increase in our reimbursable costs that are payable under the services and supply agreement which is not offset by a corresponding increase in amounts payable to us pursuant to the product purchase agreement; 95 . adversely affect the reliability or the useful life of the processing units comprising our heavy oil processing facility; or . have a material adverse effect on our operations, the heavy oil processing facility, or the Port Arthur refinery, including a material adverse effect on our ability to pay or prepay our senior debt obligations in accordance with the base case financial model included in the Independent Engineer's Report annexed hereto as Annex B. Capacity Swaps If Clark Refining & Marketing meets specified criteria and determines, in its reasonable business judgment and in conformity with prudent industry practices, that it is economically and technically prudent to process our feedstocks through another Clark Refining & Marketing processing unit at the Port Arthur refinery having substantially the same processing capabilities as a unit within our heavy oil processing facility, Clark Refining & Marketing may substitute the processing capacity of such unit with Clark Refining & Marketing's unit at our expense. Alternative Feedstocks To the extent that operational difficulties involving our leased units cause their actual capacity to be less than their design capacity, Clark Refining & Marketing must use commercially reasonable efforts to procure alternative feedstocks on our and their behalf to (1) operate the other processing units comprising the heavy oil processing facility at their actual capacities and (2) to preserve the relative processing capacities as between us and Clark Refining & Marketing as would exist if such processing units were operating at their design capacities. In such event, we will reimburse Clark Refining & Marketing for all reasonable expenses and expenditures they incur in procuring such alternative feedstocks on our behalf. Title to Product Streams Title to product streams from our heavy oil processing facility will be determined on a pro rata basis in proportion to the relative volume of our, Clark Refining & Marketing's or another third party's crude oil or other feedstocks processed through our heavy oil processing facility based on specified formulas. Defaults, Termination and Other Remedies Clark Refining & Marketing Defaults The following constitute defaults by Clark Refining & Marketing: . failure to pay us any amount in excess of $250,000 when due that continues uncured for five days; . failure to perform substantially any material obligation that remains uncured for 30 days; . commencement of insolvency, receivership, reorganization or bankruptcy proceedings by or against Clark Refining & Marketing, that are not dismissed within 60 days; . any material representation or warranty made by Clark Refining & Marketing is proven incorrect as of the time made or deemed made that remains uncured for 60 days; . failure to perform substantially any material obligation under either of our leases with Clark Refining & Marketing that remains uncured for 30 days; or . default by Clark Refining & Marketing under the product purchase agreement. Subject to any additional requirements of our senior debt documents and specified cure periods, we may terminate the services and supply agreement upon a Clark Refining & Marketing default or exercise any other remedies available to us at law or in equity. 96 Our Defaults Our failure to pay any amount due under the services and supply agreement in excess of $250,000 that remains uncured for a period of 5 days constitutes a default by us under the services and supply agreement. If we default under the services and supply agreement, Clark Refining & Marketing may terminate the agreement after first giving us and our financing parties 90 days notice and the opportunity to cure such default. Specific Performance The parties have acknowledged that monetary damages may be an inadequate remedy for a breach of any of the provisions of the services and supply agreement. In such case the parties will be entitled to specific performance of the breaching party's obligations and in any action for specific performance the parties will waive the defense that a remedy at law would be adequate. Termination Option We or Clark Refining & Marketing may terminate the services and supply agreement if final completion of our coker project and completion of the improvements and upgrades to our leased units does not occur by March 2002. Force Majeure If an event of force majeure causes a material adverse effect on a party's ability to carry out its obligations under the services and supply agreement, other than the obligation to pay money, such party is obligated to give prompt notice to the other party. In such case, these obligations so far as they are affected by such event of force majeure will be suspended during but not longer than the continuance of such event of force majeure and such further period thereafter as shall be reasonable in the circumstances. An event of force majeure is any event or circumstance if (1) such event or circumstance is beyond the reasonable control of the affected party and (2) such event or circumstance is not the direct or indirect result of a party's negligence or the failure of such party to perform any of its obligations under the services and supply agreement, including, among others: . any interruption or cessation in delivery of crude oil or other feedstocks to the Port Arthur refinery; . acts of God, earthquake, fire, explosion, tornado, hurricane, or other extraordinary weather conditions more severe than those experienced at any time in the last 30 years for the geographic area of the Port Arthur refinery; . acts of a public enemy, war, blockade, insurrection or riot; . laws, rules, regulations, orders, judgments or other acts of any foreign, federal, state or local court, administrative agency, governmental body or authority; . strikes, boycotts or lockouts, except any such strike, boycott or lockout that is not national or industry-wide that involves the employees of Clark Refining & Marketing; and . a partial or entire interruption or other failure of (1) the supply of electricity, water, wastewater treatment, steam, hydrogen or other utilities to the refinery or any part thereof, or (2) pipeline service, ship or barge service, dock access or usage or other transportation facilities. End of Term Obligations Following termination of the services and supply agreement, Clark Refining & Marketing is obligated to: . cooperate with us so that we are able to continue operating our new processing units, reclaim goods, equipment and materials, and accomplish the smooth transition of operations of such units from Clark Refining & Marketing to us or to a new manager that we engage; 97 . execute all documents and take all reasonable steps that we request needed to assign to and vest in us all rights, benefits, interest and title in connection with any contracts or obligations that Clark Refining & Marketing may have undertaken with third parties in connection with the services and supply agreement; . deliver to us all materials and documents that are our property; and . cooperate with us to effect the transfer to us of any permits held by Clark Refining & Marketing and required for our continuing operation of the heavy oil processing facility. Miscellaneous Provisions Subcontractors Clark Refining & Marketing has the right to subcontract any portion of the services and supplies it is to provide us. Clark Refining & Marketing, however, will remain primarily responsible for all of its obligations under the services and supply agreement and we will not be deemed by virtue of any Clark Refining & Marketing subcontract to have any contractual relationship or obligation to any Clark Refining & Marketing subcontractors. Dispute Resolution; Governing Law If any dispute arises regarding the services and supply agreement, our senior executives and those of Clark Refining & Marketing are obligated to meet to resolve the conflict. If we cannot resolve such conflict within specified time periods, either party may initiate an arbitration proceeding. Such arbitration will be governed by rules of the American Arbitration Association and the arbitration will be in New York. The services and supply agreement is governed by the laws of the State of New York. Assignments Clark Refining & Marketing may not assign its rights under the services and supply agreement without our prior written consent and the consent of the holders of our senior debt. We may assign our rights to our senior debt holders as collateral security for our senior debt obligations, but otherwise we may not assign our rights under the services and supply agreement without Clark Refining & Marketing's consent and the consent of our senior debt holders. The assignment of our rights under the services and supply agreement with respect to specified regulated utilities to any person will not be effective unless our rights under the facility and site lease and the ground lease are also assigned to such person. Product Purchase Agreement We and Clark Refining & Marketing entered into a product purchase agreement in August 1999, simultaneously with the issuance of the outstanding notes. Under this agreement Clark Refining & Marketing has an absolute and unconditional obligation to accept and actually take delivery of all intermediate and final products of our heavy oil processing facility that we tender for delivery and to pay us for such products in accordance with specified pricing formulas. Subject to the early termination rights of each party described below, the product purchase agreement will extend for a term of 30 years. Required Product Mix Unless Clark Refining & Marketing otherwise requests, we are obligated to use commercially reasonable efforts to meet specified target quantity and quality specifications of products to be delivered to Clark Refining & Marketing. We will, however, have no liability for failing to deliver such target specifications of products. 98 Clark Refining & Marketing, as our customer under the product purchase agreement, may request that we alter the quality and quantity of products produced by our heavy oil processing facility. In this case, we are obligated to use commercially reasonable efforts to meet the requested product specifications. These adjustments to the product mix produced by our heavy oil processing facility, however, are subject to the following conditions: . in a given calendar month, such adjustments may not cause our leased equipment to process less than the volume of Maya available to us under the long term crude oil supply agreement or, if the availability of such Maya has been curtailed, less than the amount of crude oil or other feedstocks sufficient to utilize 80% of the actual capacity of our leased units; . in a given calendar month, such adjustments may not cause our new delayed coker to process less than all the vacuum tower bottoms produced by processing our crude oil through our leased units; . such adjustments will, in Clark Refining & Marketing's reasonable good faith judgment, maximize the profitability at the Port Arthur refinery as a whole and be mutually beneficial to Clark Refining & Marketing and us; . Clark Refining & Marketing will supply us with the necessary feedstocks under the services and supply Agreement and make any needed operational and other adjustments under such agreement to fulfill such request; . such adjustments will not materially increase our net reimbursable costs payable under the services and supply agreement and not adversely affect the reliability, useful life of, or have a material adverse effect on the physical condition of our heavy oil processing facility; and . it is feasible for our heavy oil processing facility to produce the quantity and quality of products requested. Product Prices The product purchase agreement includes pricing formulas for each product expected to be produced by our heavy oil processing facility. These formulas are intended to reflect fair market pricing of these products and will be used to determine the amounts payable to us by Clark Refining & Marketing. To the extent, however, that any of our products are purchased by Clark Refining & Marketing and immediately resold to a non-affiliated third party, the price payable to us by Clark Refining & Marketing for such product will be the purchase price received by Clark Refining & Marketing from such third party less a specified marketing fee. This marketing fee is intended to be consistent with a fair market fee that would be charged by an unaffiliated third party. The cost of marketing these products would be incurred whether we sold the products directly or paid Clark Refining & Marketing or another third party to do so on our behalf. We will invoice Clark Refining & Marketing every three calendar days and Clark Refining & Marketing will be obligated to pay invoices within five calendar days of receipt. Price Adjustments for Non-Specification Products If a material amount of any product produced our the heavy oil processing facility fails to meet the target specifications used to develop the pricing formulas for the product and the failure to meet specifications has a material adverse affect on the fair market value of such product or any finished product derived from such product, then we will meet with Clark Refining & Marketing to negotiate a good faith and equitable adjustment to payments due us. Any such adjustment, however, will be conditioned on the following: . that the failure to meet specifications was not caused by a failure of Clark Refining & Marketing to operate our heavy oil processing facility in accordance with its obligations under the services and supply agreement; . the non-specification product was not requested by Clark Refining & Marketing; and . the adjustment will be effective until Purvin & Gertz, as independent engineer, issues a certificate approving the reasonableness of such adjustment. 99 If a failure to meet product specifications is due to a design or construction defect of the coker project and the failure is expected to continue, we will meet with Clark Refining & Marketing to negotiate adjustments to the applicable formulas in good faith. Such adjustments, however, will not be effective until Purvin & Gertz, as independent engineer, issues a certificate approving the reasonableness of such adjustment. Defaults, Termination and Other Remedies Clark Refining & Marketing Defaults The following constitute defaults by Clark Refining & Marketing: . failure to pay us any amount in excess of $250,000 when due that continues uncured for five days; . failure to perform substantially any material obligation that remains uncured for 30 days; . commencement of insolvency, receivership, reorganization or bankruptcy proceedings by or against Clark Refining & Marketing that are not dismissed within 60 days; . any material representation or warranty made by Clark Refining & Marketing is proven incorrect as of the time made or deemed made that remains uncured for 60 days; . failure to perform substantially any material obligation under either of our leases with Clark Refining & Marketing that remains uncured for 30 days; or . default by Clark Refining & Marketing under the services and supply agreement. Subject to the consent of our senior debt holders, we may terminate the product purchase agreement upon a Clark Refining & Marketing default or exercise any other remedies available to us at law or in equity. Our Defaults Our material failure to deliver products substantially as required under the product purchase agreement for a period of 60 days constitutes a default under the product purchase agreement. If a default occurs, Clark Refining & Marketing may terminate the agreement after first giving us and our senior debt holders 90 days notice and opportunity to cure the default. Specific Performance The parties have acknowledged that monetary damages may be an inadequate remedy for a breach of any of the provisions of the product purchase agreement and that in such case the parties will be entitled to specific performance of the breaching party's obligations. The parties have agreed that in any action for specific performance will waive the defense that a remedy at law would be adequate. Termination Option We or Clark Refining & Marketing may terminate the product purchase agreement if final completion of our coker project does not occur by March 2002. Force Majeure If an event of force majeure causes a material adverse effect on a party's ability to carry out its obligations under the product purchase agreement, other than the obligation to pay money that party is obligated to give to the other party prompt notice. In such case the party's obligations so far as they are affected by such event of force majeure will be suspended during but not longer than the continuance of such event of force majeure and such further period thereafter as shall be reasonable in the circumstances. For the purposes of the product purchase agreement, an event of force majeure will have the same meaning as it is used in the services and supply agreement and described under the caption "--Services and Supply Agreement--Force Majeure" above. 100 Miscellaneous Provisions Dispute Resolution; Governing Law If any dispute arises regarding the product purchase agreement, our senior executives and those of Clark Refining & Marketing are obligated to meet to resolve the conflict. If we cannot resolve the conflict within specified time periods, either party may initiate an arbitration proceeding. The arbitration will be governed by the rules of the American Arbitration Association and the arbitration will be in New York. The product purchase agreement is governed by the laws of the State of New York. Assignments Clark Refining & Marketing may not assign its rights under the product purchase agreement without our prior written consent and the consent of the holders of our senior debt. We may assign our rights to our senior debt holders as collateral security for our senior debt obligations, but otherwise we may not assign our rights under the product purchase agreement without Clark Refining & Marketing's consent and the consent of our senior debt holders. Facility and Site Lease We and Clark Refining & Marketing entered into a facility and site lease in August 1999, simultaneously with the issuance of the outstanding notes. Under this lease, we are leasing Clark Refining & Marketing's crude unit and vacuum tower, two of its distillate hydrotreaters and its naphtha hydrotreater. These units are located at the Port Arthur refinery. The initial term of this lease is 30 years. We may renew the lease for five additional five-year terms. Easement Clark Refining & Marketing has also granted us a nonexclusive blanket easement over and under the remaining Port Arthur refinery property necessary to own, construct and operate our coker project and to maintain and operate the units leased to us. Ancillary Equipment Upgrade Construction Obligations Clark Refining & Marketing is obligated under the facility and site lease to construct and substantially complete, specified improvements and upgrades to the processing units we are leasing before October 2000, at its cost and expense. If Clark Refining & Marketing fails to complete such improvements and upgrades on time, we may engage our own contractor to complete the work at Clark Refining & Marketing's expense. Assignment of Construction Contract As security for its obligation to perform these improvements and upgrades, Clark Refining & Marketing has collaterally assigned to us all its right, title and interest in and to any and all construction, design, engineering or procurement contracts that it enters into for purpose of completing such improvements. Rent Payments In the opinion of Purvin & Gertz, the following rent payments represent fair market rental payments for the facility and site lease term. 101 Base Rent After start-up of our coker project, we will begin making ongoing quarterly rent payments to Clark Refining & Marketing equal to approximately $8 million, or a smaller pro-rated amount in the first quarter when the payments are due. This rent amount will be adjusted over time in proportion to changes in the producer price index published by the U.S. Department of Labor. Operating Fee As additional rent, we will pay Clark Refining & Marketing an operating fee each month after start-up of our coker project for the services and supplies provided to us by Clark Refining & Marketing under the services and supply agreement and related to the on-going operation of our leased units. Such operating fee is based on the number of barrels of crude oil and other feedstocks processed through our leased units and is intended to approximate the fixed and variable costs to Clark Refining & Marketing of providing services and supplies for such leased units. This operating fee may be adjusted if Clark Refining & Marketing incurs increased costs for purchases of catalysts or other consumable materials or other expenses related to its operation of our leased equipment which are intended to increase our net revenues. In such circumstances, we and Clark Refining & Marketing are to negotiate in good faith an equitable adjustment to the calculation of the operating fee to reflect the increased costs. Any such adjustment may not have a material adverse effect on our ability to operate in accordance with the base case financial model and will not become effective until approved by the independent engineer. Governing Law The facility and site lease is governed by the laws of the State of Texas. Ground Lease Simultaneously with the issuance of the outstanding notes in August 1999, we entered into a ground lease with Clark Refining & Marketing. Under this lease, we are leasing from Clark Refining & Marketing the sites within the Port Arthur refinery on which our new processing units will be located. The initial term of the ground lease is 30 years. We may renew the ground lease for five additional five-year terms. Easements Blanket Easement Clark Refining & Marketing has granted us a nonexclusive easement over and under the remaining Port Arthur refinery property as necessary to own, construct and operate our coker project and maintain and operate the units leased to us. Dock Easement Clark Refining & Marketing has also granted us a nonexclusive easement over the docks owned by Clark Refining & Marketing located adjacent to the Port Arthur refinery for the unloading of cargoes of crude oil and other feedstocks, loading of products of our new processing units, and the construction and maintenance of pipes, pumps, valves, gauges and other equipment in connection with the loading and unloading. 102 Oil Transportation Rights Clark Refining & Marketing has also granted us a nonexclusive easement over and under pipelines and oil handling facilities needed for the transportation of crude oil to the Port Arthur refinery from the docking facilities of Sun Pipe Line Company in Nederland, Texas. License to use Additional Facilities Clark Refining & Marketing also granted us a license to use additional facilities located on the easements that it granted us and that are necessary for the ongoing operation of our new processing units. These facilities include, among others, the following locations at the refinery: . the saturated gas plant; . an amine treating unit and sour water stripper; . the wastewater treatment plant; . specified boiler houses, pump houses, power stations and cooling towers; . specified storage tanks; . the lye plant; . specified crude oil pipelines; . the hydrogen gathering, gas, steam and electrical systems; . the flare and control systems; and . maintenance, storehouse, rail and lab facilities. Rent Payments Upon the issuance of the outstanding notes, we paid Clark Refining & Marketing $25,000 as a full prepayment of rent for the initial 30 year term of the ground lease. In the opinion of Purvin & Gertz, this is an arm's length rental payment for the initial term of the ground lease. Rental payments for any renewal terms for this lease will be determined in accordance with a fair market rental valuation procedure described in detail in the lease. End of Term At the end of the term of the ground lease, we have the option of abandoning our units in place or dismantling and removing them, provided we repair any damage to the land done by our dismantling and removal of the units. Governing Law The ground lease is governed by the laws of the State of Texas. Hydrogen Supply Agreement General We have entered into a hydrogen supply agreement with Air Products and Chemicals, Inc. Under the hydrogen supply agreement, Air Products will supply us the hydrogen produced at the new hydrogen supply plant at the Port Arthur refinery. Construction of the Facility Air Products is obligated to design and construct the hydrogen supply plant according to agreed upon milestones and specifications. We and the independent engineer have the right upon reasonable written notice to Air Products to inspect the ongoing construction of the hydrogen supply plant. 103 Term The initial term of the hydrogen supply agreement will commence on the date the hydrogen supply plant is installed and "ready for commercial operation," and will continue for 246 consecutive months. However, if we begin taking hydrogen between October 2000 and December 2000, the initial term will be reduced by six days for each day after October 2000 but before December 2000 that we have begun taking hydrogen. Thereafter, the hydrogen supply agreement will remain in force from year to year unless terminated in accordance with the hydrogen supply agreement. Liquidated Damages for Delay in Construction If Air Products' hydrogen supply plant fails to be ready for commercial operation on or before December 2000, then for each day of delay beyond December 2000 due to Air Product's acts or omissions, Air Products will pay us liquidated damages of $19,250 for each day of delay up to $1.2 million. If we are unable to take the hydrogen on or before December 2000 due to our acts or omissions, we will pay Air Products liquidated damages of $38,500 for each day of delay up to approximately $1.2 million. Delivery of Hydrogen Hydrogen meeting required specifications will be delivered by Air Products to us at a specified location at the heavy oil processing facility. Title and risk of loss with respect to hydrogen will pass from Air Products to us at that delivery point. Quantities and Pricing of Hydrogen Air Products will supply and we will purchase all of our requirements for hydrogen for use by us at the Port Arthur refinery in excess of the amount of hydrogen produced internally at the Port Arthur refinery up to a maximum quantity of 80 million standard cubic feet per day at the price of $1.278 per thousand standard cubic feet. This price is subject to adjustment according to a formula based on inflation indices. In the event we have requirements for hydrogen in excess of this maximum daily amount, we may purchase such additional hydrogen at the price of $1.585 per thousand standard cubic feet. In the event we wish to increase the maximum daily amount, we and Air Products will negotiate in good faith the price, terms and conditions for such increase. Air Products has the right to supply any hydrogen required by us above this maximum daily amount by matching the terms and conditions obtained by us for such additional hydrogen requirements from a bona fide third party supplier. We will pay Air Products for a minimum quantity of hydrogen equal to 5,018.7 million standard cubic feet per calendar quarter, regardless of the quantity of hydrogen actually taken by us, except for periods of scheduled maintenance activities of up to 28 days every two years. In the event the maximum daily amount is increased for any reason, this minimum quantity of hydrogen will be increased on a proportional basis. Furthermore, Air Products may charge us a non-consumption charge for shortfalls in our hydrogen purchase activity. We will also pay Air Products a monthly base facility charge of $81,839. This price is subject to adjustment pursuant to a formula based on inflation indices. In the event the hydrogen supply plant is not operating or its production is curtailed, Air Products will supply us with our requirements for hydrogen up to the maximum daily amount, provided hydrogen is available for delivery as reasonably determined by Air Products from the pipeline network owned and operated by Air Products or its affiliates. The price for this hydrogen will be $1.585 per thousand standard cubic feet. These prices are subject to adjustment pursuant to a formula based on inflation indices. Performance Guarantee Air Products guarantees that it will produce and deliver hydrogen requested by us with a minimum on-stream factor of 98%. "On-stream factor" means the ratio of total hours in the year during which hydrogen meeting the specifications was or could have been supplied by Air Products but for the occurrence of events of 104 force majeure or scheduled maintenance outages by Air Products to total number of hours during that year. For each hour that the on-stream factor is greater than 98%, a bonus in the amount of $5,200 per hour will be paid by us to Air Products, and for each hour that the on-stream factor is less than 98%, Air Products will pay us liquidated damages in the amount of $5,200 per hour. The maximum amount of the bonus will be $900,000 per year and the maximum amount of the liquidated damages will be $1.8 million per year. Air Products is also guaranteeing the performance of specified hydrogen compressors which are part of the hydrogen supply plant up to specified performance specifications. Governmental Requirements If, in Air Products judgment, the facilities producing hydrogen for delivery to us must be modified or tests, studies or any other action must be undertaken with respect to such facilities to comply with any anticipated, proposed or final regulation, law or other governmental requirement, Air Products or the hydrogen supply plant owner must take such action following (1) in the case of a final governmental requirement, consultation with us concerning the anticipated costs and expenses to confirm that there is not a more cost effective manner to comply with such final governmental requirement or (2) in the case of an anticipated or proposed governmental requirement, our consent, which consent will not be unreasonably withheld. Air Products must also have given us prompt notice of its knowledge of any proposed governmental requirement. The costs and expenses of such modifications, tests or other action, including both fixed and variable costs, additional operating costs, applicable overheads, general and administrative expenses, financing charges and a reasonable fee, all in accordance with Air Products's normal accounting practices, will be promptly reimbursed to Air Products by us as such costs and expenses are incurred. Contaminants It is understood and contemplated by the parties that the hydrogen supply plant is designed to use utilities and air containing only normal contaminants and, therefore, if contaminants in the utilities or air, or changes in the construction or operation of facilities in or about the Port Arthur refinery, justify the relocation, repair, modification or removal of any equipment comprising the hydrogen supply plant or the installation of additional equipment, Air Products will notify us. In such case, at our election, Air Products will either (1) make the relocation, repair, modification, or removal or (2) install the additional equipment. We will reimburse Air Products for any extra costs incurred and a reasonable fee all in accordance with Air Products's normal accounting practices as such costs are incurred. Licensing, Permits and Approvals Each party will obtain, in a timely fashion, and maintain in effect, including all renewals and updates thereof, any and all professional licenses, permits or other government approvals necessary to perform its obligations and any activities related to the hydrogen supply supply agreement, including, without limitation, air emissions permits from the Texas Natural Resource Conservation Commission. Compliance with Law and Prudent Industry Standards Each party will perform its obligations and any activities related to the hydrogen supply agreement in compliance with all applicable laws and permits and in accordance with prudent industry standards, will not undertake any act or omission which will cause the other party to fail to comply with applicable laws and permits and will be in accordance with prudent industry standards. Neither party will undertake any act or omission which would cause or be likely to cause it or the other party to be subject to regulation as an "electric utility," "electric corporation," "electrical company," "public utility," "retail electric utility" or a "public utility holding company," as such terms may be revised from time to time, under any applicable laws. 105 Taxes Air Products will bear and pay all federal, state, and local taxes based upon or measured by its net income, and all franchise taxes based upon its existence or its general right to transact business. The prices stated in the hydrogen supply agreement do not include any taxes, charges, or fees other than as stated in the prior sentence. Any other taxes imposed on the hydrogen supply plant, the hydrogen supply plant site, the inventory, or upon the operation or maintenance of the hydrogen supply plant, or upon or measured by the production, manufacture, storage, sale, transportation, delivery, use or consumption of hydrogen, such taxes, charges, or fees will be paid directly by us. Force Majeure Neither party will be considered to have defaulted in the performance of its obligations or to be liable in damages for failure or delay in performance which is due to force majeure, other than the obligation to pay money, provided that the excuse of performance will be of no greater scope and no longer duration than is reasonably required because of the force majeure. For purposes of the hydrogen supply agreement, "force majeure" will include any act or event that prevents or delays the performance by either party of its obligations under the hydrogen supply agreement if and to the extent: . that act or event is beyond such party's reasonable control and not the result of such party's fault or negligence; . that party has been unable to overcome the consequences of such act or event by the exercise of reasonable commercial efforts, which may include the reasonable expenditure of funds; and . that party has given the other party notice within 10 days of the party's knowledge of the act or event giving rise to the force majeure. Subject to the satisfaction of the foregoing conditions, force majeure will include, but not be limited to, the following acts or events, or any similar and equally serious acts or events which prevent or delay the performance by a party of its obligations under the hydrogen supply agreement: . acts of God, fires, explosions, vapor releases, natural disasters, floods, perils of the sea, lightning or wind; . acts of the public enemy, wars, sabotage, insurrections, riots, strikes, boycotts or lockouts, vandalism, blockages or accidents or failure of equipment or machinery, except any strike, boycott or lockout that involves Air Products' or our employees and is not national or industry- wide or is not caused by the other party's employees; . acts by Air Products, in the case of us, or acts by us or Clark Refining & Marketing, in the case of Air Products; . a determination that such party is subject to regulation as an electric utility under applicable law regardless of whether delivery of power is prevented, ability to obtain or maintain any easement, rights-of-way, permit or license, actions of a court or public authority; . labor disputes, boycotts; and . allocation or failure of normal sources of supply of materials, transportation, energy or utilities or other causes of a similar or dissimilar nature. Under no circumstances will inability to pay monies or other economic difficulty be construed to constitute force majeure, frustration or impossibility of performance. The affected party will promptly give notice to the other party and use all reasonable efforts to remedy its inability to perform. Neither party, however, will be required to bring to an end any strike or other concerted act of workers. Warranty Air Products warrants that hydrogen delivered to us will conform to the specification set forth in the hydrogen supply agreement, and that at the time of delivery Air Products will have good title and right to transfer the same and that the same will be delivered free and clear of any lien or other encumbrances. 106 Limitation of Liability Determination of the suitability of the hydrogen furnished for the use by us is our sole responsibility, and Air Products will have no responsibility for this determination. We acknowledged in the hydrogen supply agreement that there are hazards associated with the use of hydrogen, that we understand such hazards, and that it is our responsibility to warn and protect our employees and others exposed to such hazards through our use of hydrogen. We will hold harmless, indemnify and defend Air Products from and against any liability incurred by Air Products because those warnings were not made. We have assumed all risk and liability for loss, damages or injury to persons or to our property or others arising out of the presence or use of hydrogen or from the failure to make those warnings. Except as expressly provided in the hydrogen supply agreement, Air Products will not be liable in contract or tort for any other direct damages. Except in the case of willful misconduct of Air Products, Air Products will not be liable in contract or tort for any indirect, special, incidental, or consequential damages, including by way of illustration and not of limitation, loss of use, loss of work in process, down time or loss of profits, and such limitation on damages will survive failure of an exclusive remedy. Termination The hydrogen supply agreement may be terminated by either party on account of any material default of the other in carrying out the terms of the agreement subject to a 60-day grace period. We will not terminate the hydrogen supply agreement without the consent of our financing parties. Either party may terminate the hydrogen supply agreement as of the expiration of the initial supply term or the expiration of any anniversary date thereafter by giving not less than 36 months' prior written notice to the other party. With the consent of Clark Refining & Marketing, we may terminate the hydrogen supply agreement for lack of requirements for hydrogen following contract year 10 if our management reasonably determines that our use of hydrogen at the Port Arthur refinery will permanently cease following such determination and Clark Refining & Marketing concurrently terminates the product supply agreement between Clark Refining & Marketing and Air Products. Our right of termination will be exercisable by our giving Air Products 12-months prior written notice and paying to Air Products a specified termination payment which ranges from $7.75 million to $54.4 million, depending on the number of years remaining in the initial term. Clark Refining & Marketing is a party to a separate contract with Air Products under which Clark Refining & Marketing purchases electricity, steam and hydrogen from Air Products and provides utilities to Air Products. If this contract is terminated, we have the option of assuming Clark Refining & Marketing's obligations under the contract. If we do not assume this contract, Air Products will be excused from delivering hydrogen to us. Assignment Upon notice to the other party, any or all of a party's rights, title and interest under the hydrogen supply agreement may be assigned to an affiliate, a joint venture company in which such party or its affiliate is general partner or in which such party owns at least 50% of any equity, or to any financial institution or other entity or groups thereof under the terms of financing arrangements. In the event of such an assignment other than a collateral assignment, the assignor will execute for the benefit of the other party a guarantee or similar agreement guaranteeing the performance of the obligations under the hydrogen supply agreement by the assignee. If any of our financing parties or trustees or agents acting on their behalf, or their nominees or assignees, succeeds to our rights under this hydrogen supply agreement as a result of foreclosure or similar arrangement in lieu of foreclosure, Air Products will attorn to and recognize such successor as the buyer under 107 the hydrogen supply agreement and that successor will be bound by the terms and conditions of the hydrogen supply agreement. The hydrogen supply agreement will not otherwise be assignable or transferable by either us or Air Products without the prior written consent of the other, which consent will not be unreasonably withheld. Any attempted assignment or transfer without such consent will be void. Dispute Resolution; Governing Law The parties will endeavor to resolve any dispute arising out of or relating to the hydrogen supply agreement by mediation under the rules and guidelines of the American Arbitration Association. Any controversy or claim arising out of or relating to the hydrogen supply agreement or the breach, termination or validity of the hydrogen supply agreement, which remains unresolved 45 days after appointment of a mediator, will be settled by arbitration by three arbitrators in accordance with the rules and guidelines of the American Arbitration Association. Judgment upon the award rendered by the arbitrators may be entered by any court having jurisdiction. The hydrogen supply agreement will be interpreted in accordance with and governed by the laws of the State of New York. Marine Dock and Terminaling Agreement Clark Refining & Marketing and Sun Pipe Line Company entered into a marine dock and terminaling agreement in August 1999 under which Sun Pipe Line delivers crude oil from its Nederland, Texas dock terminal facility to Clark Refining & Marketing's pipeline located on Sun Pipe Line's property. This agreement also provides for the delivery of our crude oil. Term The marine dock and terminaling agreement will be in effect until August 2000 and will be deemed automatically extended for additional one year periods unless either party gives six months notice to the other party. Facilities and Services to be Provided by Sun Facilities to be Provided by Sun Pipe Line for Clark Refining & Marketing's Non-exclusive Use . terminaling facilities consisting of lines, pipes, gauges and berths to receive and deliver crude oil . tankage facilities to store crude oil Services to be Performed by Sun Pipe Line . receive deliveries of crude oil for Clark Refining & Marketing and its affiliates at the terminaling facility . receive, store and deliver crude oil through tanks designated for Clark Refining & Marketing in accordance with Clark Refining & Marketing's instructions Properties of the Crude Oil Clark Refining & Marketing represents that the crude oil to be delivered to Sun Pipe Line can be handled in conventional non-heated crude oil tankage and pipeline systems. The crude oil is required to have properties within specified limits which include Maya. Sun Pipe Line has the right to test whether the crude oil conforms with these specifications. Fees Sun Pipe Line charges Clark Refining & Marketing the following fees: . throughput fees of $0.07 per barrel for a monthly average throughput volume of up to 70,000 barrels per day and $0.06 per barrel for all throughput in excess of 70,000 barrels per day; and . a tank rental fee of $0.16 per barrel for 15 days of storage and an ability to extend to 30 days. 108 Force Majeure In the event either party is unable to carry out its non-monetary obligations under the marine dock and terminaling agreement due to force majeure, the obligations of both parties will be suspended during the continuance of the inability. The term "force majeure" will include, among other things, the following: . acts of God, storms, floods, breakage, accident to machinery or lines of pipe, washouts; . acts of the public enemy, wars, blockades, insurrections, riots, civil disturbances, arrests, the order of any court or governmental authority having jurisdiction, explosions; . strikes, lockouts or other industrial disturbances; and . inability to obtain, or unavoidable delay in obtaining, material, equipment, right of way easements, franchises or permits. Sun Pipe Line may also require Clark Refining & Marketing to remove a portion of its crude oil in storage to comply with strategic petroleum reserve requirements in event of a national emergency. Title and Responsibility Title to crude oil delivered to the terminal will always remain with Clark Refining & Marketing or its affiliates. Sun Pipe Line's custodial responsibility for the crude oil commences when the crude oil enters the flange connection of its 30-inch dock line at the discharge line of Clark Refining & Marketing's vessel. Sun Pipe Line's custodial responsibility terminates upon Clark Refining & Marketing's receipt at the Doe Manifold preceding Clark Refining & Marketing's scraper trap with the 32-inch pipeline which continues to the refinery property. Assignment Either party may assign its interests under the marine dock and terminaling agreement with the consent of the other party. Furthermore, either party may assign its interests to a subsidiary or affiliated company, provided that the original party remains liable for full performance. Sun Pipe Line may assign its interests to a purchaser of the terminal if it or any part should be sold. Clark Refining & Marketing may assign its interests in connection with any sale of the Port Arthur refinery or to any lender or collateral trustee in connection with the financing relating to the construction involving the Port Arthur refinery. Governing Law The marine dock and terminaling agreement is governed by and construed in accordance with the laws of the State of Texas. Reimbursable Construction Contract Clark Refining & Marketing entered into a reimbursable construction contract with Foster Wheeler USA in March 1998 for construction of the refinery upgrade project. The reimbursable construction contract was amended in July 1999 to remove our coker project from Foster Wheeler USA's scope of work thereunder and conform the insurance requirements thereunder to those in the construction contract for our coker project. The scope of work in the reimbursable construction contract now includes the renovation and upgrade of the crude unit, vacuum tower and other ancillary equipment required to be performed by Clark Refining & Marketing under the facility and site lease. Under this reimbursable construction contract, Clark Refining & Marketing will pay Foster Wheeler USA based on the actual costs incurred by Foster Wheeler USA plus a profit margin rather than a fixed-cost basis. Clark Refining & Marketing is required to maintain a standby letter of credit to ensure that funds are available for payments to Foster Wheeler USA under the reimbursable construction contract. The initial amount of the letter of credit was $97 million and is required to be reduced over time by payments made by Clark Refining & Marketing to Foster Wheeler USA. Foster Wheeler USA has agreed to draw on the letter of credit and place the proceeds into an escrow account with the collateral trustee for our senior debt if the letter of credit is not renewed within 15 days prior to its expiration. Foster Wheeler USA has also separately agreed with the collateral trustee not to draw on the letter of credit or withdraw funds from the escrow account unless Purvin & Gertz, in its role as independent engineer, has certified that the work related to the requested drawing has been performed and the amounts requested are due and payable. 109 THE EXCHANGE OFFER Purpose and Effect of the Exchange Offer We have entered into a registration rights agreement with the initial purchasers of the outstanding notes in which we agreed to file a registration statement relating to an offer to exchange the outstanding notes for exchange notes. We agreed to use our reasonable best efforts to cause such registration statement to become effective within 240 days following the original issue of the outstanding notes and to pay additional interest on the outstanding notes if the exchange offer is not consummated within 270 days following the original issue of outstanding notes. The exchange notes will have terms substantially identical to the outstanding notes; except that the exchange notes will not contain terms with respect to transfer restrictions, registration rights and additional interest for failure to observe specified obligations in the registration rights agreement. The outstanding notes were issued on August 19, 1999. Under the circumstances set forth below, we will use our reasonable best efforts to cause the Commission to declare effective a shelf registration statement with respect to the resale of the outstanding notes and keep the statement effective for up to two years after the effective date of the shelf registration statement. These circumstances include: . if any changes in law, Commission rules or regulations or applicable interpretations thereof by the staff of the Commission do not permit us to effect the exchange offer as contemplated by the registration rights agreement; . if any outstanding notes validly tendered in the exchange offer are not exchanged for exchange notes within 270 days after the original issue of the outstanding notes; . if any initial purchaser of the outstanding notes so requests, but only with respect to any outstanding notes not eligible to be exchanged for exchange notes in the exchange offer; or . if any holder of the outstanding notes notifies us that it is not permitted to participate in the exchange offer or would not receive fully tradable exchange notes pursuant to the exchange offer. If we fail to comply with specified obligations under the registration rights agreement, we will be required to pay additional interest to holders of the outstanding notes. Please read the section captioned "Registration Rights Agreement" for more details regarding the registration rights agreement and the circumstances under which we will be required to pay additional interest. Each holder of outstanding notes that wishes to exchange such outstanding notes for transferable exchange notes in the exchange offer will be required to make the following representations: . any exchange notes will be acquired in the ordinary course of its business; . such holder has no arrangement with any person to participate in the distribution of the exchange notes; and . such holder is not our "affiliate," as defined in Rule 405 of the Securities Act, or if it is our affiliate, that it will comply with applicable registration and prospectus delivery requirements of the Securities Act. Resale of Exchange Notes Based on interpretations of the Commission staff set forth in no action letters issued to unrelated third parties, we believe that exchange notes issued under the exchange offer in exchange for outstanding notes may be offered for resale, resold and otherwise transferred by any exchange note holder without compliance with the registration and prospectus delivery provisions of the Securities Act, if: . such holder is not an "affiliate" of Port Arthur Finance within the meaning of Rule 405 under the Securities Act; . such exchange notes are acquired in the ordinary course of the holder's business; and 110 . the holder does not intend to participate in the distribution of such exchange notes. Any holder who tenders in the exchange offer with the intention of participating in any manner in a distribution of the exchange notes . cannot rely on the position of the staff of the Commission enunciated in "Exxon Capital Holdings Corporation" or similar interpretive letters; and . must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction. This prospectus may be used for an offer to resell, resale or other retransfer of exchange notes only as specifically set forth in this prospectus. With regard to broker-dealers, only broker-dealers that acquired the outstanding notes as a result of market-making activities or other trading activities may participate in the exchange offer. Each broker-dealer that receives exchange notes for its own account in exchange for outstanding notes, where such outstanding notes were acquired by such broker-dealer as a result of market-making activities or other trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of the exchange notes. Please read the section captioned "Plan of Distribution" for more details regarding the transfer of exchange notes. Terms of the Exchange Offer Upon the terms and subject to the conditions set forth in this prospectus and in the letter of transmittal, Port Arthur Finance will accept for exchange any outstanding notes properly tendered and not withdrawn prior to the expiration date. Port Arthur Finance will issue $1,000 principal amount of exchange notes in exchange for each $1,000 principal amount of outstanding notes surrendered under the exchange offer. Outstanding notes may be tendered only in integral multiples of $1,000. The form and terms of the exchange notes will be substantially identical to the form and terms of the outstanding notes except the exchange notes will be registered under the Securities Act, will not bear legends restricting their transfer and will not provide for any additional interest upon failure of Port Arthur Finance to fulfill its obligations under the registration rights agreement to file, and cause to be effective, a registration statement. The exchange notes will evidence the same debt as the outstanding notes. The exchange notes will be issued under and entitled to the benefits of the same indenture that authorized the issuance of the outstanding notes. Consequently, both series will be treated as a single class of debt securities under that indenture. For a description of the indenture, see "Description of Notes" below. The exchange offer is not conditioned upon any minimum aggregate principal amount of outstanding notes being tendered for exchange. As of the date of this prospectus, $255 million aggregate principal amount of the outstanding notes are outstanding. This prospectus and the letter of transmittal are being sent to all registered holders of outstanding notes. There will be no fixed record date for determining registered holders of outstanding notes entitled to participate in the exchange offer. Port Arthur Finance intends to conduct the exchange offer in accordance with the provisions of the registration rights agreement, the applicable requirements of the Securities Act and the Securities Exchange Act of 1934 and the rules and regulations of the Commission. Outstanding notes that are not tendered for exchange in the exchange offer will remain outstanding and continue to accrue interest and will be entitled to the rights and benefits such holders have under the indenture relating to the outstanding notes and the registration rights agreement. Port Arthur Finance will be deemed to have accepted for exchange properly tendered outstanding notes when we have given oral or written notice of the acceptance to the exchange agent. The exchange agent will act as agent for the tendering holders for the purposes of receiving the exchange notes from us and delivering 111 exchange notes to such holders. Subject to the terms of the registration rights agreement, Port Arthur Finance expressly reserves the right to amend or terminate the exchange offer, and not to accept for exchange any outstanding notes not previously accepted for exchange, upon the occurrence of any of the conditions specified below under the caption "--Certain Conditions to the Exchange Offer." Holders who tender outstanding notes in the exchange offer will not be required to pay brokerage commissions or fees or, subject to the instructions in the letter of transmittal, transfer taxes with respect to the exchange of outstanding notes. We will pay all charges and expenses, other than the applicable taxes described below under "--Fees and Expenses", in connection with the exchange offer. It is important that you read the section labeled "-- Fees and Expenses" below for more details regarding fees and expenses incurred in the exchange offer. Expiration Date; Extensions; Amendments The exchange offer will expire at 5:00 p.m., New York City time on , 2000, unless in its sole discretion, Port Arthur Finance extends it. In order to extend the exchange offer, Port Arthur Finance will notify the exchange agent orally or in writing of any extension. Port Arthur Finance will notify the registered holders of outstanding notes of the extension no later than 9:00 a.m., New York City time, on the business day after the previously scheduled expiration date. Port Arthur Finance reserves the right, in its sole discretion: . to delay accepting for exchange any outstanding notes; . to extend the exchange offer or to terminate the exchange offer and to refuse to accept outstanding notes not previously accepted if any of the conditions set forth below under "--Conditions to the Exchange Offer" have not been satisfied, by giving oral or written notice of such delay, extension or termination to the exchange agent; or . subject to the terms of the registration rights agreement, to amend the terms of the exchange offer in any manner. Any such delay in acceptance, extension, termination or amendment will be followed as promptly as practicable by oral or written notice thereof to the registered holders of outstanding notes. If Port Arthur Finance amends the exchange offer in a manner that it determines to constitute a material change, Port Arthur Finance will promptly disclose such amendment in a manner reasonably calculated to inform the holders of outstanding notes of such amendment. Without limiting the manner in which it may choose to make public announcements of any delay in acceptance, extension, termination or amendment of the exchange offer, Port Arthur Finance shall have no obligation to publish, advertise, or otherwise communicate any such public announcement, other than by making a timely release to a financial news service. Conditions to the Exchange Offer Despite any other term of the exchange offer, Port Arthur Finance will not be required to accept for exchange, or exchange any exchange notes for, any outstanding notes, and Port Arthur Finance may terminate the exchange offer as provided in this prospectus before accepting any outstanding notes for exchange if in its reasonable judgment: . the exchange notes to be received will not be tradeable by the holder, without restriction under the Securities Act, the Securities Exchange Act of 1934 and without material restrictions under the blue sky or securities laws of substantially all of the states of the United States; . the exchange offer, or the making any exchange by a holder of outstanding notes, would violate applicable law or any applicable interpretation of the staff of the Commission; or 112 . any action or proceeding has been instituted or threatened in any court or by or before any governmental agency with respect to the exchange offer that, in Port Arthur Finance's judgment, would reasonably be expected to impair the ability of Port Arthur Finance to proceed with the exchange offer. In addition, Port Arthur Finance will not be obligated to accept for exchange the outstanding notes of any holder that has not made to it . the representations described under "--Purpose and Effect of the Exchange Offer," "--Procedures for Tendering" and "Plan of Distribution", and . such other representations as may be reasonably necessary under applicable Commission rules, regulations or interpretations to make available to an appropriate form for registration of the exchange notes under the Securities Act. Port Arthur Finance expressly reserves the right, at any time or at various times, to extend the period of time during which the exchange offer is open. Consequently, it may delay acceptance of any outstanding notes by giving oral or written notice of such extension to their holders. During any such extensions, all outstanding notes previously tendered will remain subject to the exchange offer, and Port Arthur Finance may accept them for exchange. Port Arthur Finance will return any outstanding notes that it does not accept for exchange for any reason without expense to their tendering holder as promptly as practicable after the expiration or termination of the exchange offer. Port Arthur Finance expressly reserves the right to amend or terminate the exchange offer, and to reject for exchange any outstanding notes not previously accepted for exchange, upon the occurrence of any of the conditions of the exchange offer specified above. Port Arthur Finance will give oral or written notice of any extension, amendment, non-acceptance or termination to the holders of the outstanding notes as promptly as practicable. In the case of any extension, such notice will be issued no later than 9:00 a.m., New York City time, on the business day after the previously scheduled expiration date. These conditions are for the sole benefit of Port Arthur Finance and Port Arthur Finance may assert them regardless of the circumstances that may give rise to them or waive them in whole or in part at any or at various times in our sole discretion. If Port Arthur Finance fails at any time to exercise any of the foregoing rights, this failure will not constitute a waiver of such right. Each such right will be deemed an ongoing right that Port Arthur Finance may assert at any time or at various times. In addition, Port Arthur Finance will not accept for exchange any outstanding notes tendered, and will not issue exchange notes in exchange for any such outstanding notes, if at such time any stop order will be threatened or in effect with respect to the registration statement of which this prospectus constitutes a part or the qualification of the indenture under the Trust Indenture Act of 1939. Procedures for Tendering Only a holder of outstanding notes may tender such outstanding notes in the exchange offer. To tender in the exchange offer, a holder must: . complete, sign and date the letter of transmittal, or a facsimile of the letter of transmittal; have the signature on the letter of transmittal guaranteed if the letter of transmittal so requires; and mail or deliver such letter of transmittal or facsimile to the exchange agent prior to the expiration date; or . comply with DTC's Automated Tender Offer Program procedures described below. In addition, either: . the exchange agent must receive outstanding notes along with the letter of transmittal; or . the exchange agent must receive, prior to the expiration date, a timely confirmation of book-entry transfer of such outstanding notes into the exchange agent's account at DTC according to the procedure for book- entry transfer described below or a properly transmitted agent's message; or 113 . the holder must comply with the guaranteed delivery procedures described below. To be tendered effectively, the exchange agent must receive any physical delivery of the letter of transmittal and other required documents at the address set forth below under "--Exchange Agent" prior to the expiration date. The tender by a holder that is not withdrawn prior to the expiration date will constitute an agreement between such holder and Port Arthur Finance in accordance with the terms and subject to the conditions set forth in this prospectus and in the letter of transmittal. The method of delivery of outstanding notes, the letter of transmittal and all other required documents to the exchange agent is at the holder's election and risk. Rather than mail these items, Port Arthur Finance recommends that holders use an overnight or hand delivery service. In all cases, holders should allow sufficient time to assure delivery to the exchange agent before the expiration date. Holders should not send the letter of transmittal or outstanding notes to Port Arthur Finance Holders may request their respective brokers, dealers, commercial banks, trust companies or other nominees to effect the above transactions for them. Any beneficial owner whose outstanding notes are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and who wishes to tender should contact the registered holder promptly and instruct it to tender on the owner's behalf. If such beneficial owner wishes to tender on its own behalf, it must, prior to completing and executing the letter of transmittal and delivering its outstanding notes; either: . make appropriate arrangements to register ownership of the outstanding notes in such owner's name; or . obtain a properly completed bond power from the registered holder of outstanding notes. The transfer of registered ownership may take considerable time and may not be completed prior to the expiration date. Signatures on a letter of transmittal or a notice of withdrawal described below must be guaranteed by a member firm of a registered national securities exchange or of the National Association of Securities Dealers, Inc., a commercial bank or trust company having an office or correspondent in the United States or another "eligible guarantor institution" within the meaning of Rule 17Ad-15 under the Exchange Act, unless the outstanding notes tendered pursuant thereto are tendered: . by a registered holder who has not competed the box entitled "Special Issuance Instructions" or "Special Delivery Instructions" on the letter of transmittal; or . for the account of an eligible guarantor institution. If the letter of transmittal is signed by a person other than the registered holder of any outstanding notes listed on the outstanding notes, such outstanding notes must be endorsed or accompanied by a properly completed bond power. The bond power must be signed by the registered holder as the registered holder's name appears on the outstanding notes and an eligible institution must guarantee the signature on the bond power. If the letter of transmittal or any outstanding notes or bond powers are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, such persons should so indicate when signing. Unless waived by us, they should also submit evidence satisfactory to us of their authority to deliver the letter of transmittal. The exchange agent and DTC have confirmed that any financial institution that is a participant in DTC's system may use DTC's Automated Tender Offer Program to tender. Participants in the program may, instead of physically completing and signing the letter of transmittal and delivering it to the exchange agent, transmit their acceptance of the exchange offer electronically. They may do so by causing DTC to transfer the outstanding 114 notes to the exchange agent in accordance with its procedures for transfer. DTC will then send an agent's message to the exchange agent. The term "agent's message" means a message transmitted by DTC, received by the exchange agent and forming part of the book-entry confirmation, to the effect that: . DTC has received an express acknowledgment from a participant in its Automated Tender Offer Program that is tendering outstanding notes that are the subject of such book-entry confirmation; . such participant has received and agrees to be bound by the terms of the letter of transmittal, or, in the case of an agent's message relating to guaranteed delivery, that such participant has received and agrees to be bound by the applicable notice of guaranteed delivery; and . the agreement may be enforced against such participant. Port Arthur Finance will determine in its sole discretion all questions as to the validity, form, eligibility, including time of receipt, acceptance of tendered outstanding notes and withdrawal of tendered outstanding notes. Port Arthur Finance's determination will be final and binding. Port Arthur Finance reserves the absolute right to reject any outstanding notes not properly tendered or any outstanding notes our acceptance of which would, in the opinion of our counsel, be unlawful. Port Arthur Finance also reserves the right to waive any defects, irregularities or conditions of tender as to particular outstanding notes. Port Arthur Finance's interpretation of the terms and conditions of the exchange offer, including the instructions in the letter of transmittal, will be final and binding on all parties. Unless waived, any defects or irregularities in connection with tenders of outstanding notes must be cured within such time as Port Arthur Finance shall determine. Although Port Arthur Finance intends to notify holders of defects or irregularities with respect to tenders of outstanding notes, neither it, the exchange agent nor any other person will incur any liability for failure to give such notification. Tenders of outstanding notes will not be deemed made until such defects or irregularities have been cured or waived. Any outstanding notes received by the exchange agent that are not properly tendered and as to which the defects or irregularities have not been cured or waived will be returned to the exchange agent without cost to the tendering holder, unless otherwise provided in the letter of transmittal, as soon as practicable following the expiration date. In all cases, Port Arthur Finance will issue exchange notes for outstanding notes that it has accepted for exchange under the exchange offer only after the exchange agent timely receives: . outstanding notes or a timely book-entry confirmation of such outstanding notes into the exchange agent's account at DTC; and . a properly completed and duly executed letter of transmittal and all other required documents or a properly transmitted agent's message. By signing the letter of transmittal, each tendering holder of outstanding notes will represent to Port Arthur Finance that, among other things: . any exchange notes that the holder receives will be acquired in the ordinary course of its business; . the holder has no arrangement or understanding with any person or entity to participate in the distribution of the exchange notes; . if the holder is not a broker-dealer, that it is not engaged in and does not intend to engage in the distribution of the exchange notes; . if the holder is a broker-dealer that will receive exchange notes for its own account in exchange for outstanding notes that were acquired as a result of market-making activities, that it will deliver a prospectus, as required by law, in connection with any resale of such exchange notes; and . the holder is not an "affiliate," as defined in Rule 405 of the Securities Act, of Port Arthur Finance or, if the holder is an affiliate, it will comply with any applicable registration and prospectus delivery requirements of the Securities Act. 115 Book-Entry Transfer The exchange agent will make a request to establish an account with respect to the outstanding notes at DTC for purposes of the exchange offer promptly after the date of this prospectus; and any financial institution participating in DTC's system may make book-entry delivery of outstanding notes by causing DTC to transfer such outstanding notes into the exchange agent's account at DTC in accordance with DTC's procedures for transfer. Holders of outstanding notes who are unable to deliver confirmation of the book-entry tender of their outstanding notes into the exchange agent's account at DTC or all other documents required by the letter of transmittal to the exchange agent on or prior to the expiration date must tender their outstanding notes according to the guaranteed delivery procedures described below. Guaranteed Delivery Procedures Holders wishing to tender their outstanding notes but whose outstanding notes are not immediately available or who cannot deliver their outstanding notes, the letter of transmittal or any other required documents to the exchange agent or comply with the applicable procedures under DTC's Automated Tender Offer Program prior to the expiration date may tender if: . the tender is made through an eligible institution; . prior to the expiration date, the exchange agent receives from such eligible guarantor institution either a properly completed and duly executed notice of guaranteed delivery, by facsimile transmission, mail or hand delivery, or a properly transmitted agent's message and notice of guaranteed delivery: . setting forth the name and address of the holder, the registered number(s) of such outstanding notes and the principal amount of outstanding notes tendered; . stating that the tender is being made thereby; . guaranteeing that, within three (3) New York Stock Exchange trading days after the expiration date, the letter of transmittal, or facsimile of the letter of transmittal, together with the outstanding notes or a book-entry confirmation, and any other documents required by the letter of transmittal will be deposited by the Eligible Institution with the exchange agent; and . the exchange agent receives such properly completed and executed letter of transmittal, or facsimile of the letter of transmittal, as well as all tendered outstanding notes in proper form for transfer or a book- entry confirmation, and all other documents required by the letter of transmittal, within three (3) New York State Exchange trading days after the expiration date. Upon request to the exchange agent, a notice of guaranteed delivery will be sent to holders who wish to tender their outstanding notes according to the guaranteed delivery procedures set forth above. Withdrawal of Tenders Except as otherwise provided in this prospectus, holders of outstanding notes may withdraw their tenders at any time prior to the expiration date. For a withdrawal to be effective: . the exchange agent must receive a written notice, which may be by telegram, telex, facsimile transmission or letter, of withdrawal at one of the addresses set forth below under "--Exchange Agent", or . holders must comply with the appropriate procedures of DTC's Automated Tender Offer Program system. Any such notice of withdrawal must: . specify the name of the person who tendered the outstanding notes to be withdrawn . identify the outstanding notes to be withdrawn, including the principal amount of such outstanding notes; and 116 . where certificates for outstanding notes have been transmitted, specify the name in which such outstanding notes were registered, if different from that of the withdrawing holder. If certificates for outstanding notes have been delivered or otherwise identified to the exchange agent, then, prior to the release of such certificates, the withdrawing holder must also submit: . the serial numbers of the particular certificates to be withdrawn; and . a signed notice of withdrawal with signatures guaranteed by an eligible institution unless such holder is an eligible institution. If outstanding notes have been tendered pursuant to the procedure for book- entry transfer described above, any notice of withdrawal must specify the name and number of the account at DTC to be credited with the withdrawn outstanding notes and otherwise comply with the procedures of such facility.

Consequences of Failure to Exchange Holders of outstanding notes who do not exchange their outstanding notes for exchange notes under the exchange offer will remain subject to the restrictions on transfer of such outstanding notes: . as set forth in the legend printed on the notes as a consequence of the issuance of the outstanding notes pursuant to the exemptions from, or in transactions not subject to, the registration requirements of the Securities Act and applicable state securities laws; and . otherwise set forth in the offering memorandum distributed in connection with the private offering of the outstanding notes. In general, you may not offer or sell the outstanding notes unless they are registered under the Securities Act, or if the offer or sale is exempt from registration under the Securities Act and applicable state securities laws. Except as required by the registration rights agreement, we do not intend to register resales of the outstanding notes under the Securities Act. Based on interpretations of the Commission staff, exchange notes issued pursuant to the exchange offer may be offered for resale, resold or otherwise transferred by their holders, other than any such holder that is our "affiliate" within the meaning of Rule 405 under the Securities Act, without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that the holders acquired the exchange notes in the ordinary course of the holders' business and the holders have no arrangement or understanding with respect to the distribution of the exchange notes to be acquired in the exchange offer.

The collateral securing the notes is shared, on an equal and ratable basis, with the other senior lenders, any replacement senior lenders and other secured parties and is described in greater detail under "Description of Our Principal Financing Documents--Common Security Agreement--Scope and Nature of the Security Interest." Ranking of the Notes The notes: . are senior secured indebtedness of Port Arthur Finance; . rank equivalent in right of payment to all other senior indebtedness of Port Arthur Finance, Port Arthur Coker Company, Sabine River and Neches River and our payment obligations under the guaranty insurance policy; and . rank senior in right of payment to all existing and future subordinate indebtedness of Port Arthur Finance, Port Arthur Coker Company, Sabine River and Neches River. Redemption at Our Option We may choose to redeem some or all of the notes at any time, without the consent of noteholders, at a redemption price equal to 100% of the outstanding unpaid principal amount of notes being redeemed plus accrued and unpaid interest, if any, up to but excluding the applicable redemption date plus a make-whole 121 premium. The make-whole premium will be equal to the excess, if positive, of (1) the present value of all interest and unpaid principal payments scheduled to be made on the notes, at a discount rate equal to 75 basis points over the yield to maturity on the U.S. treasury instruments with a maturity as close as practicable to the remaining average life of the notes, over (2) the unpaid principal amount of the notes to be redeemed. Notice of redemption will be mailed by the indenture trustee to each noteholder at that noteholder's address of record not less than 30 days nor more than 60 days prior to the date of redemption. On the date of redemption, the redemption price will become due and payable on each note to be redeemed and interest thereon will cease to accrue on and after such date. Mandatory Redemption If we receive specified mandatory payment proceeds, which includes insurance proceeds from casualty events, condemnation compensation and late payments to the extent not needed to pay interest on the senior debt and buy-down payments from Foster Wheeler USA, we are required to redeem all our outstanding senior debt on an equal and ratable basis. The redemption price for the notes will be equal to 100% of the unpaid principal amount of notes being redeemed, plus accrued but unpaid interest, if any, on the notes being redeemed, up to but excluding the date of redemption. The mandatory redemption provisions governing the notes are described in greater detail under "Description of Our Principal Financing Documents--Common Security Agreement--Mandatory Prepayments." Repurchases by Us Subject to the terms of the common security agreement, we or our respective affiliates may at any time purchase the notes in the open market or otherwise at any price agreed upon between us and the applicable holders. Any note so purchased by us must be surrendered to the indenture trustee for cancellation and may not be re-issued or resold. Transfer and Exchange A noteholder may transfer or exchange notes only in accordance with and subject to the restrictions on transfer contained in the indenture. Satisfaction and Discharge Under specified circumstances, we can deposit funds with the indenture trustee sufficient to pay and discharge the indebtedness on any outstanding notes. In that case, we would cease to have any obligations under the indenture. Indenture Subject to Common Security Agreement The indenture trustee has entered into the common security agreement and other financing documents on behalf of all noteholders from time to time. All rights, powers and remedies available to the indenture trustee and the noteholders and all future noteholders, under the common security agreement and the other financing documents are in addition to those under the indenture. In the event of any conflict or inconsistency between the terms and provisions of the indenture and the common security agreement, the terms of the common security agreement govern and control. Intercreditor Arrangements In the event that any consent, approval, waiver or other direction of the senior lenders is sought by the indenture trustee or the collateral trustee pursuant to the common security agreement and the matter with respect to which such consent, approval, waiver or direction as sought is a matter that the indenture trustee is entitled to vote on under the common security agreement as representative of the noteholders, the indenture trustee, promptly upon the receipt of notice from the collateral trustee describing the action to be voted, will be 122 obligated to promptly notify the holders and duly convene a meeting of holders, whose instructions may be conveyed by written consent, to canvass the holders as to votes to be cast by the indenture trustee regarding the matter. If no instructions are so issued, the indenture trustee will be obligated to abstain from voting.

Further Issues and Additional Securities From time to time we may, without notice to or the consent of the holders of the notes, create and issue further notes ranking equally and ratably with the notes in all respects, or in all respects except for the payment of interest accruing prior to the issue date of such further notes or except for the first payment of interest following the issue date of such further notes, and so that such further notes will be consolidated and form a single series with the notes and will have the same terms as to status, redemption or otherwise as the notes. In addition, we may issue additional debt securities on terms agreed by us and the underwriters of those securities. In each case described above we may issue the further notes or additional debt securities pursuant to a supplemental indenture. The issuance and application of the proceeds of any additional notes or other securities will be subject to the requirements applicable to additional senior debt or replacement senior debt in the common security agreement, described in "Description of Our Principal Financing Documents--Common Security Agreement--Additional Senior Debt" and "-- Replacement Senior Debt." Notices and Reports We are required to give notice to the indenture trustee of any event which requires that notice be given to the noteholders, in sufficient time for the indenture trustee to provide such notice to the noteholders in the manner provided by the indenture. Also, the common security agreement provides that upon request of a beneficial owner, we will provide directly to such beneficial owner any financial information regarding us that we are required to provide to the indenture trustee pursuant to the indenture or the common security agreement. The indenture trustee will transmit to noteholders such information, documents and reports, and their summaries, concerning the indenture trustee and its actions under the common security agreement as may be required and at the times and in the manner provided in the common security agreement. 123 All notices regarding the notes will be deemed to have been sufficiently given upon the mailing by first-class mail, postage prepaid, of such notices to each holder at the address of such holder as it appears in the security register, in each case not earlier than the earliest date and not later than the latest date prescribed in the indenture for the giving of such notice.

Also, we may maintain in an unsecured operating account up to 30 days' of our operating expenses. Withdrawals from Accounts Pre-Default.

Surplus Reserve Account in an amount equal to the amount, if any, by which the P.M.I. surplus under the long term crude oil supply agreement exceeds the balance in the P.M.I.

Eleventh, after final completion, as defined in the construction contract, to make Restricted Payments as described in "--Restricted Payments" below. In any event, withdrawals from the Project Revenue Account for any purpose other than those described under "First" above will only be permitted if and to the extent that the funds then on deposit in the Project Revenue Account exceed the aggregate amount of all outstanding invoices in respect of our payment obligations under the long term crude oil supply agreement. Withdrawals from Accounts During the Continuance of a Default. If a Default has occurred and is continuing, the senior lender(s) may notify the collateral trustee that the collateral trustee will no longer accept instructions from us for the investment, withdrawal or transfer of funds or investments in the secured accounts. The depositary bank will thereafter accept instructions for the investment, withdrawal or transfer of funds or investments in these secured accounts solely from the collateral trustee or other person(s) designated by the collateral trustee. The collateral trustee will invest project funds only in Authorized Investments. The collateral trustee will give the depositary bank prompt notice of these circumstances. Following the receipt by the collateral trustee of such notice from the senior lender(s) declaring a Default, and until such time as a cessation notice has been given by any senior lender that the Default has been cured, or an Enforcement Action is taken by the senior lenders the collateral trustee will exercise its rights to instruct the depositary bank in a manner that causes available funds in the accounts to be applied in the order of priority set forth in the pre-Default waterfall described above, except that (1) no funds will be credited to the Distribution Account and (2) any reimbursement obligations that remain unpaid after the expiration of 30 days following the giving of a Priority Termination Notice as described in "Description of Our Principal Financing Documents--Guaranty Insurance Policy and Reimbursement Agreement" below will rank equally and ratably 128 in right of payment with the senior debt obligations then due and payable. Funds not distributed pursuant to these provisions or the pre-Default waterfall described above will remain in the Project Revenue Account. As an exception to the foregoing, immediately before the expiration of the 30-day period referred to above, the collateral trustee will apply any funds on deposit in the Project Revenue Account, less any amounts earmarked to pay outstanding invoices for purchases of crude oil or our other operating expenses in the ordinary course of business, to the repayment of outstanding reimbursement obligations. Upon receipt by the collateral trustee of a cessation notice with respect to a Default that is continuing, the collateral trustee will immediately notify the depositary bank, with a copy to us, directing the depositary bank once again to accept our directions, and the collateral trustee and the depositary bank will again accept our directions in respect of investment, withdrawal and transfer of funds in the secured accounts. Debt Service Reserve Account On each semiannual Payment Date we are required to deposit cash from the following sources into the Debt Service Reserve Account up to the aggregate amount of principal and interest due on the senior debt on the next Payment Date: . in accordance with the seventh and ninth priority positions in "-- Withdrawal from Accounts Pre-Default" above; . after the repayment of any principal amounts outstanding under the debt service reserve insurance guarantee, from 25% of the cash available at the tenth priority position in "--Withdrawal from Accounts Pre-Default" above that would otherwise have been applied to repay such principal amounts in accordance with the financing documents; and . after the repayment of all construction and term loans, from 75% of the cash available at the tenth priority position in "--Withdrawal from Accounts Pre-Default" above that would otherwise have been applied to repay such construction and term loans in accordance with the financing documents. The balance in the Debt Service Reserve Account at any time of determination will be deemed to be the aggregate of: . the amount of cash then on deposit in the Debt Service Reserve Account; . the market value of any Authorized Investments then on deposit in the Debt Service Reserve Account; and . the amount available under the debt service reserve insurance guarantee. If no Default has occurred and is continuing, we may direct the collateral trustee to apply the funds in the Debt Service Reserve Account at any time to pay senior debt obligations, and at any time on or after a Priority Termination Date, oil payment reimbursement obligations, then due and payable on the date of withdrawal or within five business days, but only to the extent that there are insufficient funds in the Principal & Interest Accrual Account to make the required debt service payment. Post-default withdrawals will be made in accordance with "--Withdrawals from Accounts Post-Default" above.

Second, to the payment of all fees, costs, expenses, indemnities and any other amounts that we owe to the secured parties and the whole amount then outstanding of senior debt obligations or reimbursement obligations and in case such moneys will not be sufficient to pay in full the whole amount due and unpaid, then to make equal and ratable payments, without any preference or priority, as among the secured parties, provided that any amounts that we owe to the oil payment insurers in respect of reimbursement obligations relating to shipments of Maya pursuant to the long term crude oil supply agreement for which title passed to us after the notice from senior lenders to the oil payment insurers administrative agent will have priority over any amounts owed to the senior lenders in respect of senior debt obligations, except to the extent that funds on deposit in the Debt Service Reserve Account have been applied to pay such reimbursement obligations; and . Third, after the payment in full of the senior debt obligations and the reimbursement obligations, to us or our successors, or in the case of proceeds from the transfer or disposition of all or part of the interests in Sabine River or Neches River to the Shareholders or Sabine River, as the case may be, or as a court of competent jurisdiction may otherwise direct. Mandatory Prepayments Prepayments with Specified Proceeds Subject to our bank loan agreements, we will apply any of the following proceeds to the prepayment of senior loans, and, in specified circumstances, to prepayment of reimbursement obligations, made by the bank senior lenders and the noteholders: . any loss proceeds in respect of any catastrophic casualty to project property, except to the extent that they relate to any shipment of Maya for which (1) the oil payment insurers have made, or are obligated to make, payment to P.M.I. Comercio Internacional under the oil payment guaranty insurance policy or (2) the bank senior lenders have provided cash advances or letters of credit under the secured working capital facility, to the extent that such loss proceeds are not applied toward repairing, replacing or restoring the relevant project property; . any insurance proceeds in respect of any casualty to project property, to the extent that those proceeds will not be used to repair or replace the relevant project property; and . any late payments, which are not needed to pay interest, buy down payments or other payments received from Foster Wheeler USA pursuant to the construction contract to the extent we do not need to direct these funds to the payment of interest on the senior debt. Prepayments of Bank Senior Debt We will make prepayments of the bank senior debt but not the notes, on each payment date after start-up in an amount equal to 75% of excess cash flow, such amount to be determined no earlier than on each payment date. Prepayments of Senior Debt and Oil Payment Insurance Obligations We will apply the following to the prepayment of senior loans and reimbursement obligations: . any loss proceeds in respect of any catastrophic casualty to project property, except to the extent 140 that they relate to any shipment of Maya for which (1) the oil payment insurers have made, or are obligated to make, payment to P.M.I. Comercio Internacional under the oil payment guaranty insurance policy or (2) the bank senior lenders have provided cash advances or letters of credit under the secured working capital facility, to the extent that such loss proceeds are not applied toward repairing, replacing or restoring the relevant project property; . any delay in start-up, business interruption or contingent business interruption insurance proceeds that are not transferred to the Project Revenue Account; and . upon receipt, any condemnation compensation by governmental authority. Application of Prepayments Mandatory prepayments other than those that we make with the 75% of excess cash flow will be applied equally and ratably between the senior bank loans and the notes to reduce remaining principal installments equally and ratably as to each remaining principal installment outstanding. Mandatory prepayments that we make toward the bank senior debt with the 75% of excess cash flow will be applied in direct order of maturity until the principal due on the immediately succeeding Payment Date has been paid in full and then to reduce the remaining principal installments of senior bank loans in the inverse order of their maturity. If any mandatory prepayments required to be made are applied to reimbursement obligations outstanding at the time of prepayment, the amount or amounts prepaid will be applied equally and ratably between senior bank loans and such reimbursement obligations. Insurance Proceeds Within 60 days following the occurrence of a catastrophic casualty, we will deliver to the collateral trustee a plan for the application of these insurance proceeds and other funds available that are available to us to restore, repair or replace the project property. If, within 45 days following the later of the receipt by the collateral trustee of this plan and the deposit of these proceeds into the Catastrophic Casualty Account, Majority Lenders, or, in specified circumstances, Majority Secured Parties, notify us that in their reasonable judgment it is unlikely that, after implementation of our plan, we would be able to pay the senior debt obligations as and when they come due or be able to produce product production of substantially the same or higher quality and quantity as prior to such loss, the casualty insurance proceeds will remain in the Catastrophic Casualty Account, and we may be required to apply the proceeds to prepay senior debt and to direct the collateral trustee to transfer the relevant casualty insurance proceeds from the Catastrophic Casualty Account to the Mandatory Prepayments Account. Prepayments arising out of these insurance proceeds will be made within two business days following such transfer. The senior lenders will have the option, at our expense, to consult with the independent engineer for purposes of reviewing any plan for the application of such casualty insurance proceeds with respect to which Majority Lenders or Majority Secured Parties, as the case may be, have the right to object. Promptly upon the receipt of any loss proceeds relating to any shipment of Maya, we will instruct the collateral trustee to transfer such loss proceeds, to the extent the oil payment insurers have made, or are obligated to make, payment to P.M.I. Comercio Internacional under the oil payment guaranty insurance policy in respect of such shipment, from the Casualty and Insurance Account or the Catastrophic Casualty Account, as the case may be, to an account specified for such purpose by the oil payment insurers administrative agent. Optional Prepayments We may make optional prepayments with respect to the senior bank loans and the notes at any time upon 30 days' prior notice to the collateral trustee and the Applicable Agent. Any optional prepayment must be accompanied by any prepayment compensation required under the applicable credit agreements. Optional 141 prepayments will be applied to reduce the remaining principal installments of senior loans in the order such remaining principal installments become due. Pro Rata and Non-Pro Rata Payments Pro Rata Payments With respect to the senior bank loans and the notes, each payment, optional prepayment or mandatory prepayment that we will make to a senior lender in respect of senior debt obligations, other than an optional prepayment or mandatory prepayment made in accordance with the following paragraph, will be an equal and ratable payment among the senior bank loans and the notes. Non-Pro Rata Prepayments Subject to the terms of the senior loan agreements, we may: . make an optional prepayment, in whole or in part, of senior loans owed to senior lenders in one or more senior lender groups without making an equal and ratable payment to any senior lenders in any other senior lender group if: . such payment is made with equity funding; . such payment is made with the proceeds of Replacement Senior Debt incurred by us; or . such payment is made from funds otherwise available for Restricted Payments; . make an optional prepayment of senior loans owed to all senior lenders without making any prepayment to the capital markets senior lenders, provided that such optional prepayment is a pro rata payment among all senior lenders, other than the capital markets senior lenders; or . make a mandatory prepayment in whole or in part of senior debt obligations owed to any bank senior lender if such mandatory prepayment is made in accordance with the bank senior loan agreement, or any other senior lender that is entitled to such mandatory prepayment as compensation for costs incurred by it in connection with making or maintaining its senior loans under its senior loan agreement or indenture, as applicable, in excess of costs incurred generally by the other senior lenders, or because it has become unlawful for it to honor its obligation to make or maintain senior loans under its senior loan agreement or indenture, as applicable, and it has not become unlawful generally for the other senior lenders to honor their obligations to make or maintain senior loans to us under their senior loan agreements, in either case without making an equal and ratable payment to any other senior lenders, provided that (1) such payment or prepayment is made with equity funding, (2) such payment or prepayment is made with the proceeds of Replacement Senior Debt incurred by us or (3) such payment or prepayment is made from funds otherwise available for Restricted Payments. Additional Senior Debt We may incur, in addition to the initial senior debt, the reimbursement obligations and any Replacement Senior Debt and without the prior consent of the senior lenders or the oil payment insurers, Additional Senior Debt secured by the same common security package, subject to the following conditions: . if we plan to use the proceeds of the Additional Senior Debt solely to finance or refinance mandatory capital expenditures, a responsible officer must certify to the collateral trustee and the independent engineer that: . no Event of Default or Potential Default has occurred and is continuing; . the amount and scope of such mandatory capital expenditures are necessary to comply with a change in applicable environmental, health, safety or other laws or regulations binding on us or are otherwise necessary to operate the heavy oil processing facility; and . after giving effect to the incurrence of all Additional Senior Debt, and based on reasonable assumptions verified by the independent engineer: 142 . the minimum Debt Service Coverage Ratio for each remaining calendar year through final maturity of the senior debt will be not less than 1.5:1.0; and . the average annual Debt Service Coverage Ratio from the date of incurrence of the Additional Senior Debt through final maturity of the senior debt will be not less than 2.0:1.0; . if, at any time after substantial reliability, we plan to use the proceeds of such Additional Senior Debt solely to finance or refinance discretionary capital expenditures, a responsible officer must certify to the collateral trustee and the independent engineer confirms that, among other things: . no Event of Default or Potential Default has occurred and is continuing; . substantial reliability has occurred; . after giving effect to the incurrence of all additional senior debt, and based on reasonable assumptions verified by the independent engineer: . the minimum Debt Service Coverage Ratio for each remaining calendar year through final maturity of the Senior Debt as set forth in the base case model will be not less than 2.0:1.0; and . the average annual debt service coverage ratio from the date of incurrence of such additional senior debt through final maturity of the senior debt as set forth in the base case model will be not less than 2.6:1.0; and . we must obtain a credit rating reaffirmation for the notes by both Moody's and Standard & Poor's; . the aggregate principal amount of all such Additional Senior Debt for discretionary capital expenditures does not exceed $20 million if any bank senior debt remains outstanding, or $50 million if no bank senior debt remains outstanding; . that Additional Senior Debt ranks in right of payment, upon liquidation and in all other respects on an equal and ratable basis with all other senior debt without preference among senior debt obligations by reason of date of incurrence or otherwise and has none of the preferences with respect to reimbursement obligations; and . the lender of the Additional Senior Debt has executed and delivered to the collateral trustee an agreement, which includes a copy of the proposed senior loan agreement relating to the Additional Senior Debt, setting out that it agrees: . to become a party to the common security agreement and the transfer restrictions agreement described under "Description of Our Principal Financing Documents--Transfer Restrictions Agreement" below; . to be bound as a senior lender by all the terms and conditions of the common security agreement and the transfer restrictions agreement; and . to perform all the obligations of a senior lender under the common security agreement and the transfer restrictions agreement. Any incurrence of Additional Senior Debt other than in accordance with the above terms will require the prior consent of Requisite Lenders. Replacement Senior Debt We may incur Replacement Senior Debt, secured by the same common security package and entitled to the benefits of the common security agreement and the security documents, to replace the initial senior debt, without the consent of the senior lenders or the oil payment insurers for the purpose of paying or prepaying all or any part of the initial senior debt or replacing all or part of the unutilized or canceled part of the related outstanding senior debt commitments, subject to the specified conditions including the following: . the aggregate principal amount of such Replacement Senior Debt does not exceed the sum of 143 the amount of senior debt obligations being paid or prepaid and the unutilized or canceled part of the senior debt commitments being replaced; . the Replacement Senior Debt has a Weighted Average Life no shorter, and a final maturity date no earlier, than that of the Senior Debt being replaced; . the projected average debt service coverage ratio through January 15, 2009, calculated on a pro forma basis reflecting the incurrence of the Replacement Senior Debt but not modifying any of the other assumptions made in the base case model described in Annex B to this prospectus is not less than 2.2:1.0; and . we have obtained a reaffirmation of the then current credit rating of notes by both Moody's and Standard & Poor's, provided that no reaffirmation will be required if the Replacement Senior Debt is Bank Senior Debt and bears interest at a rate, or, in the case of a floating rate facility, a margin, that is equal to or lower than that on the Bank Senior Debt being replaced and no changes other than the interest rate or margin, as applicable, or administrative, procedural, mechanical or other de minimis changes are made. Any incurrence of Replacement Senior Debt other than in accordance with these conditions will require the prior consent of Requisite Lenders. Replacement for Oil Payment Guaranty Insurance Policy We may enter into one or more letters of credit or similar instruments satisfying the requirements of the long term crude oil supply agreement to replace the oil payment insurance guaranty policy in its entirety, but not in part, without the consent of the senior lenders or the oil payment insurers, provided that the conditions specified in the common security agreement are satisfied. Guarantee Each of Port Arthur Coker Company, Sabine River and Neches River have unconditionally and fully guaranteed jointly and severally, all obligations of Port Arthur Finance under the common security agreement and the other financing documents. Governing Law The common security agreement is governed by the laws of the State of New York. Secured Construction and Term Loan Agreement We, the bank senior lenders and the bank lenders administrative agent entered into a loan agreement, dated as of August 19, 1999, that provides for our borrowing from the bank senior lenders $325 million to finance the construction, development and operation of our coker project. The secured construction and term loan facility is split into a Tranche A of $225 million with a term of 7.5 years and a Tranche B of $100 million with a term of 8 years. Under specified circumstances, the aggregate amount of the construction and term loan facility may be reallocated between the tranches with our consent, which may not be unreasonably withheld. In November 1999, the bank senior lenders requested that we reallocate $5 million from Tranche A to Tranche B. Tranche A loans will be amortized over time. As required under the secured construction and term loan agreement, we drewdown the entire amount of the Tranche B loans in October 1999. Other than the $500,000 semiannual principal payments discussed below, all principal amount of the Tranche B loans will be due and payable on maturity. Drawdowns of the construction and term loans must be accompanied by equal and ratable contributions of equity or deeply subordinated debt from Blackstone and Occidental. We will make interest and principal payments on the Tranche A loans semiannually on each January 15 and July 15, commencing on January 15, 2000 in the case of interest and on January 15, 2002 in the case of principal. With respect to the Tranche B loans, we will make interest payments quarterly on each January 15, April 15, July 15 and October 15, commencing on January 15, 2000, and we will make principal payments in the amount of $500,000 semiannually on each January 15 and July 15, commencing on January 15, 2002, with the remaining principal being repaid in full on the maturity date. 144 Senior debt obligations under the construction and term loan agreement rank equally and ratably in right of payment and liquidation with each other and with all other senior debt obligations. Senior debt obligations under the construction and term loan agreement in general also rank equally and ratably in right of liquidation with our reimbursement obligations relating to the oil payment guaranty insurance policy described under "Description of Our Principal Financing Documents--Guaranty Insurance Policy and Reimbursement Agreement" below, but will generally rank junior in right of payment to those reimbursement obligations. Secured Working Capital Facility Under a secured working capital facility, the bank senior lenders will provide us up to $35 million of working capital in the form of cash advances or letters of credit. In February 2000, our working capital facility was reduced from $75 million to $35 million. The $40 million reduction, a portion of which had been outstanding in the form of a letter of credit to P.M.I. Comercio Internacional to secure against a default by us under our long term oil supply agreement, was replaced by an insurance policy under which an affiliate of American International Group agreed to insure P.M.I. Comercio Internacional against our default under the long term oil supply agreement up to a maximum liability of $40 million. This affiliate of American International Group is treated as a bank senior lender under the common security agreement. The $35 million available under the secured working capital facility may be used to meet cash needs of our coker project. Drawdowns under the secured working capital facility, other than letters of credit provided in connection with the long term crude oil supply agreement, will rank equally and ratably in right of payment and liquidation with all other senior debt obligations. The letters of credit provided in connection with the long term crude oil supply agreement will rank equally and ratably, in all respects, with our reimbursement obligations relating to the oil payment guaranty insurance policy. Oil Payment Guaranty Insurance Policy and Reimbursement Agreement Winterthur issued an oil payment guaranty insurance policy for the benefit of P.M.I. Comercio Internacional in order to guarantee our payment obligations to P.M.I. Comercio Internacional under the long term crude oil supply agreement for shipments of Maya. We will pay the premiums and any interest with respect to any amounts drawn under the oil payment guaranty insurance policy to Winterthur. Winterthur will reinsure a portion of its exposure under the oil payment guaranty insurance policy with a syndicate of reinsurers. Maximum Amount. For the period from and including the coverage start date to and including the date on which we give the full coverage start notice to the oil payment insurers, the maximum coverage amount is $15 million, and after that period, the maximum coverage amount is $150 million. In each case, the coverage available to us is the maximum amount less any outstanding reimbursement obligations that we owe to the oil payment insurers. Coverage Period. The coverage must start no later than March 1, 2001, subject to extension up to October 1, 2001, provided that Majority Secured Parties may vote to extend the outside start date up to March 1, 2002. Coverage under the oil payment guaranty insurance policy will terminate upon the earlier of (1) 10.5 years after the closing date and (2) the date on which all senior debt obligations have been repaid in full. Premiums. The annual premium was paid in advance on August 19, 1999, and will be payable annually in advance on each anniversary of such date. Security. Under the reimbursement agreement, payments by the oil payment insurers to P.M.I. Comercio Internacional on our behalf give rise to reimbursement obligations in favor of the oil payment insurers that we must repay. The oil payment insurers will be a party to, and get the benefit of, the common security agreement, the intercreditor agreement and the transfer restrictions agreement. In particular, the oil payment insurers share on an equal and ratable basis in the first priority security interest in all collateral granted to all secured parties under the common security agreement, but have the possibility for priority access as described under "--Payment and Liquidation Priorities" below. 145 Payment and Liquidation Priorities. For purposes of the cash waterfall in the common security agreement, reimbursement obligations will at all times rank below our operating expenses but above senior debt obligations. However, if senior lenders, following the occurrence of an Event of Default, notify the oil payment insurers administrative agent that the oil payment insurers priority position will terminate, any reimbursement obligations that remain unpaid after 30 days following the effectiveness of that notice will be treated like senior debt obligations in the cash waterfall. Immediately prior to the expiration of that 30-day period, the collateral trustee will be instructed to apply any amounts that are then on deposit in the Project Revenue Account, less any amount earmarked to pay outstanding invoices for oil payments or other project expenses in the ordinary course of business, to repay any outstanding reimbursement obligations. For purposes of liquidation rights, oil payment insurers administrative agents generally rank equally and ratably with all other senior debt. If, however, an Event of Default occurs under the common security agreement, but senior lenders do not notify the oil payment insurers administrative agent that the oil payment insurers' priority position will terminate, then the oil payment insurers have the right to request the senior lenders to permit satisfaction in full of all reimbursement obligations then outstanding. If and to the extent that outstanding reimbursement obligations are not satisfied within the 30 calendar days immediately following notice from us to the collateral trustee and the administrative agents of the relevant default, then any and all reimbursement obligations arising in respect of shipments of Maya originating after the notice from us will have priority in right of liquidation, in addition to the payment priority described above, over all other senior debt. Voting Rights. Upon the expiration of the 30-day period referred to above, the oil payment insurers will become vested with all voting rights of senior debt holders, to the extent of reimbursement obligations then outstanding. At all other times, the oil payment insurers will have voting rights, based upon the maximum amount, only under specified circumstances. Suspension Events. Upon the occurrence of any of the following events and following five days notice to P.M.I. Comercio Internacional, the oil payment insurers may in their sole discretion suspend the coverage provided with respect to any shipments of Maya thereafter, provided that shipments for which title has already passed to us will continue to be covered by the oil payment guaranty insurance policy: . if (1) the premium for the oil payment guaranty insurance policy is not paid in full when due, (2) such default is not cured within 10 business days immediately following the due date and (3) P.M.I. Comercio Internacional has been notified, then the oil payment guaranty insurance policy coverage may be suspended for the relevant year until the premium is paid in full; and . if (1) senior lenders have notified the oil payment insurers administrative agent that the oil payment insurers' priority position will terminate, then the coverage will be suspended for the duration of the relevant default. Termination Events. Upon the occurrence of any of the following events and following five days notice thereof to P.M.I. Comercio Internacional, Winterthur may in its sole discretion terminate, or, at its election, suspend, the coverage provided with respect to any shipments of Maya thereafter, provided that shipments for which title has already passed to us will continue to be covered by the oil payment guaranty insurance policy: . an Event of Default under the common security agreement caused by a payment default or termination of principal project documents has occurred and continued for at least six months; . an insolvency event has occurred with respect to (1) at any time, any of us, Sabine River or Neches River or (2) prior to substantial reliability, Blackstone; . abandonment has occurred; . senior lenders are taking Enforcement Action under the common security agreement in respect of any other Event of Default; 146 . the coverage provided by the oil payment guaranty insurance policy has been suspended for at least 30 consecutive days, or, if applicable, 30 consecutive days following the expiration of any cure period; or . we have failed to give Winterthur a notice to start coverage under the oil payment guaranty insurance policy by the dates set forth in "-- Coverage Period" above. If Winterthur gives notice of suspension or termination of the oil payment guaranty insurance policy to P.M.I. Comercio Internacional more than five days but less than eight days prior to the scheduled loading of one of our Maya shipments, P.M.I. Comercio Internacional's claim under the oil payment guaranty insurance policy may include the liquidated damages payable with respect to late cancellations of scheduled shipments under the long term crude oil supply agreement in an amount equal to 15% of the price of the cancelled shipment. We, the oil payment insurers and the oil payment insurers administrative agent entered into a reimbursement agreement dated as of August 19, 1999. Pursuant to the reimbursement agreement, payments made by the oil payment insurers in respect of a claim by P.M.I. Comercio Internacional under the oil payment guaranty insurance policy will result in our corresponding, immediately payable reimbursement obligations that are due no later than six months following the date of their incurrence. In addition, to the extent the oil payment insurers have made payments with respect to particular shipments of Maya, it will be subrogated to any and all rights we may have (1) against any other insurer with respect to such shipments, for example, based upon marine or casualty insurance, or (2) against the beneficiary for any payments to be returned. Oil payment insurance reimbursement obligations will accrue interest on a daily basis at a rate per annum of 7-day LIBOR plus the applicable margin plus 2%. Any failure by us to pay in full any oil payment insurers administrative agent within the six months following the incurrence of such oil payment insurers administrative agent will constitute an Event of Default under the common security agreement. Debt Service Reserve Insurance Guarantee Winterthur issued a debt service reserve insurance guarantee on August 19, 1999, for the benefit of the secured parties in order to guarantee up to $60 million to the credit of the Debt Service Reserve Account. However, we and the collateral trustee may mutually agree to reduce this amount permanently. Winterthur will reissue a portion of its exposure under the debt service reserve insurance guarantee with the same syndicate of reinsurers that will reinsure the guaranty insurance policy. The debt service reserve insurance guarantee is available if, and only to the extent that, the funds then on deposit in the Principal & Interest Accrual Account and the Debt Service Reserve Account are insufficient to make scheduled payments on the senior debt on a payment date. The amount that may be drawn on any Payment Date is equal to the aggregate amount of senior debt obligations then due less (1) the balance in the Principal & Interest Accrual Account and (2) the balance in the Debt Service Reserve Account, including, in each of cases (1) and (2), cash and any Authorized Investments. We may not draw down solely for the purpose of covering any shortfall in the Debt Service Reserve Account at any time if no senior debt obligations are then due. Coverage Period. Drawings will be permitted during the period commencing on the date substantial reliability is achieved and ending on the tenth Payment Date after that date, provided that the coverage will automatically terminate early if and when the debt service reserve insurance guarantee is replaced. Premium and Interest. We paid the annual premium for the coverage provided by the agreement in advance on August 19, 1999, and must pay the premium annually in advance on each anniversary such date. Any amounts that we draw down under this arrangement will accrue interest on a daily basis at a rate of 500 bps above 7-day LIBOR. 147 Subordination. Payments of interest on drawdowns under this arrangement will be subordinated in right of payment to (1) the prior payment in full of all senior debt obligations and all oil payment insurance obligations related to the guaranty insurance policy then due and (2) any deposits then required to be made into the Principal and Interest Accrual Account, Tax Reserve Account, Major Maintenance Account, Debt Service Reserve Account and P.M.I. Surplus Reserve Account, but excluding any Restricted Payments. Payments of principal in respect of drawdowns will be further subordinated. We may only make repayments of principal in respect of drawdowns under the agreement on a Payment Date, after applying the 75% of the cash flow available at priority position tenth under "--Common Security Agreement--Accounts Structure-- Withdrawal from Accounts Pre-Default" to the prepayment of bank senior debt obligations as set forth in the common security agreement. Once the bank senior debt is repaid, we may repay principal in respect of drawdowns using 100% of such cash flow, as set forth in the common security agreement. Pledge. Winterthur is required to pledge any amounts extended under the debt service reserve insurance guarantee to the secured parties. Subordinated Lien on Collateral. Winterthur has a subordinated lien on all collateral that we have pledged to the senior lenders. This subordinated lien secures our obligation to reimburse Winterthur for payments made by it under the debt service reserve insurance guaranty. Scheduled Contributions to Debt Service Reserve Account. Pursuant to the common security agreement, on the sixth Payment Date and each of the four immediately succeeding Payment Dates, we must deposit at least $12 million into the Debt Service Reserve Account, but no deposits will be required to the extent the minimum balance of the Debt Service Reserve Account required at any time has already been reached through payments out of excess cash flow as described below. Upon each deposit, the guarantee amount available under this arrangement will be automatically and permanently reduced by a corresponding amount. These scheduled contributions to the Debt Service Reserve Account will be subordinated in right of payment to payments of interest on drawdowns under the arrangement. Replacement of Debt Service Reserve Insurance Guarantee. On each Payment Date after substantial reliability during the coverage period, so long as no principal amount drawn under the agreement remains outstanding, we will be required to transfer additional funds to the Debt Service Reserve Account in an amount equal to 25% of the cash flow available at priority position tenth under "--Common Security Agreement--Accounts--Withdrawal from Accounts Pre-Default" after applying 75% of such cash flow to the prepayment of bank senior debt. At any time when the construction and term loans are repaid and all commitments to lend under those loans have been terminated, we will be required to transfer funds in an amount equal to 100% of such cash flow to the Debt Service Reserve Account. Upon each such transfer, the guarantee amount available under this arrangement will be automatically and permanently reduced by a corresponding amount. If and when the Debt Service Reserve Account has been fully funded up to the amount of senior debt obligations due within the succeeding six-month period, this arrangement will automatically terminate and thereafter the obligation to fund the Debt Service Reserve Account will rest solely with us. Acceleration. Our obligations under this arrangement cannot be accelerated and no Event of Default can be declared by Winterthur unless and until (1) the secured parties have done so pursuant to the common security agreement or (2) all outstanding senior debt obligations have been repaid in full, whichever occurs first. Transfer Restrictions Agreement We, Clark Refining Holdings, Sabine River, Neches River, Blackstone, the collateral trustee, the bank lenders administrative agent, the oil payment insurers administrative agent and the indenture trustee entered into a transfer restrictions agreement, dated as of August 19, 1999, that generally provides that none of us, Clark Refining Holdings, Sabine River, Neches River nor Blackstone will effect, or permit any Affiliate to 148 effect, any transfer of such party's direct or indirect interest, if any, in us, Clark Refining & Marketing or the Port Arthur refinery. Transfers will be permitted in limited situations, including those set forth below. Transfers by Blackstone. Blackstone has the right to dispose of its equity interest in Clark Refining Holdings: . prior to final completion of our coker project: . to a transferee that is rated investment grade by both Standard & Poor's and Moody's after giving effect to the transfer; or . any other transferee with (1) the affirmative vote of 51% of bank lenders and (2) the affirmative vote of 51% of the noteholders or the reaffirmation by both Standard & Poor's and Moody's of the then- current credit rating applicable to the notes, provided that either Blackstone retains its equity funding commitment obligation or the transferee assumes such obligations; or . in part but not in whole by means of a primary or secondary public or Rule 144A offering or private sale, so long as Blackstone (1) retains not less than 40% of the total capital stock outstanding of Clark Refining Holdings or (2) remains the largest single direct or indirect shareholder of Clark Refining Holdings and maintains the direct or indirect right to appoint no fewer than one-third of the members of the board of directors of Clark Refining Holdings provided in each case that Blackstone retains its obligations to fund any unfunded equity commitment; and . following final completion of our coker project, in any manner. Transfers by Clark Refining Holdings. Following final completion, Clark Refining Holdings may dispose of its indirect interest in the Port Arthur refinery, Clark Refining & Marketing and Port Arthur Coker Company, in whole but not in part, to a transferee that is engaged in petroleum refinery operations or continuous chemical processes, provided that if the transferee is not rated investment grade by both Standard & Poor's and Moody's after the transfer, (1) Clark Refining Holdings has obtained the consent of Majority Lenders and (2) Standard & Poor's and Moody's have reaffirmed the rating on the Senior Debt at or above the then-current rating, provided further that, in any case, if the transfer is by means other than a transfer of all the shares of Clark Refining & Marketing or Clark USA, the transferee assumes all obligations of Clark Refining & Marketing with respect to the coker project. Other Transfers. Any other transfer will require the consent of requisite lenders. Intercreditor Agreement The intercreditor agreement governs the rights and obligations, including sharing of information, notice of non-pro rata payments, general consultation, voting restrictions and termination of commitments, among the collateral trustee, acting on behalf of the secured parties, the bank lenders administrative agent, acting on behalf of the bank senior lenders, the oil payment insurers administrative agent, acting on behalf of the oil payment insurers, and the indenture trustee, acting on behalf of the noteholders. Registration Rights Agreement Pursuant to the registration rights agreement, we have agreed with the initial purchasers, for the benefit of the holders of the notes, that we will file and use our reasonable best efforts to cause to become effective, at our cost, either a registration statement with respect to a registered offer to exchange the notes for a series of debt securities which are in all material respects substantially identical to the notes or a shelf registration covering resales of the notes. Upon a registration statement with respect to the exchange offer being declared effective, we will offer the exchange notes in return for surrender of the notes. The offer will remain open for no less than 20 business days after the date notice of the exchange offer is mailed to you. For each outstanding 149 note surrendered to us under the exchange offer, you will receive exchange notes in an equal principal amount. Interest on each exchange note will accrue from the last date on which interest was paid on the outstanding note so surrendered or, if no interest has been paid, since August 19, 1999. In the event that we determine in good faith that applicable interpretations of the staff of the Securities and Exchange Commission or other circumstances specified in the registration rights agreement do not permit us to effect such an exchange offer, or we so elect, we will, at our cost, use reasonable best efforts, subject to customary representations and agreements of the noteholders to have a shelf registration statement covering resale of the notes declared effective and kept effective for up to two years after the closing date, subject to specified exceptions in the registration rights agreement. We will, in the event of such a shelf registration, provide to each noteholder copies of the prospectus, notify noteholders when a registration statement for the notes has become effective and take other actions as are appropriate to permit resale of the notes. In the event that such exchange offer is not consummated or such registration statement is not declared effective within 270 days following the closing date, the annual interest rates on the notes will increase by one half of one percent, 50 basis points, effective on the 271st day following the closing date, which increase will remain in effect until the date on which such exchange offer is consummated or such registration statement will have become effective. Each noteholder who wishes to exchange its outstanding notes for exchange notes in the exchange offer will be required to represent, among other things, that any exchange notes to be received by it will be acquired in the ordinary course of business and that at the time of the commencement of the exchange offer it will have no arrangement with any person to participate in the distribution of the exchange notes within the meaning of the Securities Act. A noteholder that sells its notes pursuant to a shelf registration generally will be required to be named as a selling holder in the related prospectus and to deliver a prospectus to purchasers, will be subject to applicable civil liability provisions under the Securities Act in connection with such sale and will be required to agree in writing to be bound by the provisions of the registration rights agreement which are applicable to such noteholder, including indemnification obligations.

Procedures for tendering outstanding notes in the exchange offer through the DTC book-entry system are described under "The Exchange Offer--Book Entry Transfer." 154 SPECIAL LEGAL ASPECTS We have taken steps in structuring the transactions contemplated hereby that are intended to ensure that the voluntary or involuntary application for relief under the United States Bankruptcy Code or similar state laws by Clark Refining & Marketing, Clark Refining Holdings or Clark USA will not result in the consolidation of our assets and liabilities with those of such entities or any of their affiliates, other than Blackstone, Occidental, Sabine River or Neches River. These steps include: . the appointment of an independent director to the board of directors of each of the two corporate partners of Port Arthur Coker Company and to Port Arthur Finance; . our creation, and the creation of Sabine River and Neches River, pursuant to organizational documents containing limitations, including restrictions on the nature of our and their, business and restrictions on our, and their, ability to commence a voluntary case or proceeding under bankruptcy law with respect to ourselves without the prior unanimous affirmative vote of all of our, or their, directors; . the on-going maintenance of Occidental's 10% common equity ownership in Sabine River separate and independent from the ownership interest of Clark Refining Holdings; . the operation of our new processing units by our own employees and our employment of an individual responsible for our accounting and . our agreement to covenants intended to ensure the maintenance of our separate existence, including, among other covenants, to maintain separate books and records, to conduct our business in our own name. However, notwithstanding the foregoing, we cannot assure you that our activities would not result in a court concluding that our assets and liabilities should be consolidated with those of Clark Refining & Marketing, Clark Refining Holdings or Clark USA in a proceeding under any bankruptcy law. If a court were to reach such a conclusion, then delays in distributions on the notes could occur or reductions in the amounts of such distributions could result. We have received an opinion of our counsel to the effect that, subject to specified facts, assumptions and qualifications, it would not be a proper exercise by a court of its equitable discretion to disregard separate existence and to require the consolidation of our assets and liabilities with the assets and liabilities of Clark Refining & Marketing, Clark Refining Holdings or Clark USA in the event of the application of any bankruptcy law to any of these entities. Such opinion, however, points out that the risk of substantive consolidation may be higher in a situation in which unique assets critical to the business operations and successful reorganization of the bankrupt--so called "core assets"--are held by a related entity and there is relatively little judicial experience with respect to assets that may be considered "core assets" of a debtor. In addition, among other things, this opinion of counsel assumes, for purposes of such opinion, that we will follow procedures in the conduct of our affairs, including maintaining separate records, books of account and bank accounts, maintaining adequate capital, refraining from commingling our assets and refraining from holding ourselves out as having agreed to pay, or being liable for, each other's debts and that the 10% equity interest of Occidental in our general partner will be maintained and no portion of such interest will be transferred, directly or indirectly to Clark Refining & Marketing, Clark Refining Holdings or Clark USA. We and Clark Refining & Marketing will represent to such counsel that we and Clark Refining & Marketing will follow these and other procedures related to maintaining our separate existence. 155 U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE EXCHANGE OFFER Exchange of Notes The following summary describes the material U.S. federal income tax consequences of the exchange offer.

In other words, the processing of a crude oil with a higher API gravity should result in increased yields of higher valued products when compared to the processing of a crude oil with a lower API gravity. "backcast": a financial modeling method used by Purvin & Gertz in its report, which is included in this prospectus as Annex B, to analyze expected cash flows, debt service coverage ratios and other financial results of our coker project using a price set for crude oil and refined products based on actual prices for a representative time period in the recent past. "barrels per stream day" or "barrels per day": a measurement of the capacity of a particular processing unit to process feedstocks on a daily basis. A barrel is equal to forty-two gallons. Barrels per stream day is based on the number of days a unit is operating while per day is based on calendar days. "coker gross margin": the difference or "spread" between the market price of intermediate refined products from operation of our coking unit and the cost of producing feedstocks for the coking unit. "configuration": this term is described under the caption "The U.S. Petroleum Refining Industry and Refinery Configuration--Refinery Configuration" in this prospectus and refers to the number, types and sequencing of processing units at a refinery. "conversion capacity": a measure of the capability of a refinery or a group of refineries to upgrade crude oil into lighter refined products, such as gasoline, jet and diesel fuel. "crude oil distillation capacity": a measure of the capability of a refinery or a group of refineries to process crude oil into refined products. Generally used to described overall world-wide or country-specific capacity to process crude oil. "crude unit": this processing unit is described in the sections captioned "Prospectus Summary--Overview" and "Our Coker Project--Clark Refining & Marketing's Portion of the Refinery Upgrade Project" in this prospectus. "delayed coking unit" or "coker": this processing unit is described in the sections captioned "Prospectus Summary--Overview" and "Our Coker Project--Our Portion of the Refinery Upgrade Project" in this prospectus. "distillation": the refining process of separating crude oil components by heating and subsequent cooling. The simplest and least costly refining process. "distillates": a term for the products of distillation that is commonly used to refer to diesel fuel, jet fuel and home heating oil. "feedstocks": the raw materials needed for a refinery processing unit to produce a particular refined product. "final or finished refined products": petroleum products for which a commercial market exists without need for additional refining. "fuel oil" or "distillate fuel oil": lighter more valuable and marketable fuel oils, as distinguished from residual fuel oil. Fuel oils are generally used for diesel fuel and residential heating and are classified in grades, called number 1, 2, 3, 4, or 6 fuel oil. "heavy/light differential": the dollar per barrel price difference between heavy sour crude oil and light sweet crude oil, which is used as an indication of the profitability advantage of a heavy coking refinery as described in this prospectus under the caption "The U.S. Petroleum Refining Industry and Refinery Configuration--Heavy/Light Differential." 160 "heavy sour crude oil": crude oil with a lower API gravity that contains significant impurities and sulfur. "hydrotreater": this processing unit is described in the sections captioned "Prospectus Summary--Overview" and "Our Coker Project--Clark Refining & Marketing's Portion of the Refinery Upgrade Project" in this prospectus. "intermediate refined products": petroleum products that are generally considered to need additional refining prior to becoming commercially saleable. "light sweet crude oil": crude oil with a higher API gravity that is substantially free of impurities and sulfur. "Maya": the type of heavy sour crude oil available under our long-term crude oil supply agreement and the type of crude oil used by Purvin & Gertz as a proxy for all heavy sour crude oils when calculating the heavy/light differential. "refined products": petroleum products that result from the refining process. "refining": the process of receiving crude oil, breaking it down into various components and blending the components into useful products. "refining margin": the difference or "spread" between market prices for refined products that a refinery produces and the cost of the crude oil and other feedstocks processed by a refinery. "residue" or "residual fuel oil": the substance that is leftover after the refining process has extracted the desirable, and more marketable, products such as gasoline, kerosene and distillate fuel oil. Residual fuel oil is used mainly for heavy industrial fuel and in the manufacturing of asphalt. "Solomon complexity rating": an oil industry standard for comparing refineries based on the complexity of their configurations. A more "complex" refinery such as one with conversion capacity generally produces a more valuable mix of products. "spot market": a market for purchase and sale of crude oil or other oil products on a short-term or one-time basis. "throughput capacity": a measurement of the capacity of a refinery or a particular processing unit at a refinery to process crude oil or another feedstock, generally expressed in barrels per day. "sulfur complex": these processing units are described in the sections captioned "Prospectus Summary--Overview" and "Our Coker Project--Our Portion of the Refinery Upgrade Project" in this prospectus.

AND SUBSIDIARY (A Development Stage Company) NOTES TO CONSOLIDATED FINANCIAL STATEMENTS For the period from May 4 (inception) to December 31, 1999 1. Nature of Business Port Arthur Coker Company L.P. (the "Company") was formed as a Delaware limited partnership on May 4, 1999. The Company was formed to construct, own, operate and finance a new 80,000 barrel per stream day delayed coker unit, a 35,000 barrel per stream day hydrocracker and a 417 long tons per day sulfur complex and related assets (the "Coker Project") at the Port Arthur, Texas refinery of an affiliate, Clark Refining & Marketing, Inc ("Clark Refining & Marketing"). Port Arthur Coker Company L.P. is owned 1% by its general partner, Sabine River Holding Corp. ("Sabine River"), and 99% by its limited partner, Neches River Holding Corp. ("Neches River"). Both partners were incorporated in Delaware in May 1999. Sabine River is owned 90% by Clark Refining Holdings Inc. ("Clark Refining Holdings") and 10% by Occidental Petroleum Corporation ("Occidental"). Neches River is owned 100% by Sabine River. After giving effect to anticipated equity contributions to be made in connection with the funding of the projects, Clark Refining Holdings will be owned, indirectly through subsidiaries, by Blackstone Capital Partners III Merchant Banking Fund L.P. and its affiliates ("Blackstone") with an approximately 82% interest, and by Occidental with an approximately 17% interest. The Company is an affiliate of Clark Refining & Marketing because Clark Refining Holdings owns 100% of the capital stock of Clark USA, Inc., which in turn owns 100% of the capital stock of Clark Refining & Marketing. As of the date hereof, Port Arthur Coker Company and its subsidiary have not conducted any operations and are in the development stage. In order to fund the Company's Coker Project, in August 1999 the Company, through a wholly-owned subsidiary, Port Arthur Finance Corp. ("Port Arthur Finance"), issued $255 million in notes, entered into a $325 million secured construction and term loan facility, obtained a $75 million secured working capital facility and entered into equity subscription agreements totaling $135 million (see Note 7-- Long-Term Debt). Port Arthur Finance, a Delaware holding company, was formed on May 4, 1999. Port Arthur Finance's organizational documents only allow it to engage in activities related to issuing notes and borrowing under bank credit facilities in connection with the initial financing of the Company, and remitting the proceeds thereof to the Company. In issuing the notes and borrowing under the bank credit facilities, Port Arthur Finance is acting as an agent of the Company. In March 1998, Clark Refining & Marketing announced that it had entered into a long-term crude oil supply agreement with P.M.I. Comercio Internacional, S.A. de C.V. ("PMI"), an affiliate of Petroleos Mexicanos, the Mexican state oil company. The contract provided Clark Refining & Marketing with the foundation necessary to continue developing a project to upgrade its Port Arthur, Texas refinery to process primarily lower-cost, heavy sour crude oil. The project includes the construction of additional coking and hydrocracking capability, and the expansion of crude unit capacity to approximately 250,000 barrels per day. The oil supply agreement with PMI and the construction work-in-progress related to the new processing units were transferred at fair market value to the Company in the third quarter of 1999. In connection with the project, Clark Refining & Marketing will lease certain existing processing units of Clark Refining & Marketing to the Company on fair market terms and, pursuant to this lease, will be obligated to make certain modifications, infrastructure improvements and incur certain development costs during 1999 and 2000 at an estimated cost up to $120 million. To secure this commitment, Clark Refining & Marketing posted a letter of credit in the amount of $97 million at the closing. As of December 31, 1999, Clark Refining & Marketing had expended approximately $51 million towards this commitment. In addition, the Company entered into agreements with Clark Refining & Marketing pursuant to which Clark Refining & Marketing will provide certain operating, maintenance and other services and will purchase the output from the new coking and hydrocracking equipment for further processing into finished products. The Company also entered into agreements under which the Company will process certain hydrocarbon streams owned by Clark Refining & Marketing. F-7 2. Summary of Significant Accounting Policies Principles of Consolidation The consolidated financial statements include the accounts of the Company's wholly-owned subsidiary Port Arthur Finance. All significant intercompany transactions have been eliminated from the consolidated financial statements. 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 disclosure of contingent assets and liabilities at the dates of financial statements and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimates. Cash and cash equivalents The Company considers all highly liquid investments, such as time deposits, money market instruments, commercial paper and United States and foreign government securities, purchased with an original maturity of three months or less, to be cash equivalents. Cash and cash equivalents as of December 31, 1999, approximated fair value. Construction in Progress All additions are recorded at cost and are currently included in Construction in Progress because the Coker Project is under construction. When the assets are in operation, depreciation of plant and equipment will be computed using the straight-line method over the estimated useful lives of the assets or group of assets. The Company capitalizes the interest cost associated with major construction projects based on the effective interest rate on aggregate borrowings applied to expenditures from date of project inception to start-up. Expenditures for maintenance and repairs are expensed. Major replacements and additions are capitalized. Gains and losses on assets depreciated on an individual basis are reflected in the results from operations. The Company reviews long-lived assets for impairments whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Environmental Costs Environmental liabilities are recorded when environmental assessments and/or remedial efforts are probable and can be reasonably estimated. Environmental expenditures are expensed or capitalized depending upon their future economic benefit. Costs that improve a property as compared with the condition of the property when originally constructed or acquired and costs that prevent future environmental contamination are capitalized. Costs that return a property to its condition at the time of acquisition or original construction are expensed. Income Taxes The Company is classified as a partnership for U.S. federal income tax purposes and, accordingly, does not pay federal income tax. The Company files a U.S. partnership return of income and its taxable income or loss flows through to its partners who report and are taxed on their distributive shares of such taxable income or loss. Accordingly, no federal income taxes have been provided by the Company. Port Arthur Finance files a separate U.S. federal income tax return and computes its provision on a separate company basis. Deferred taxes are classified as current or noncurrent depending on the classification of the assets and liabilities to which the temporary differences relate. Deferred taxes arising from temporary F-8 differences that are not related to a specific asset or liability are classified as current or noncurrent depending on the periods in which the temporary differences are expected to reverse. 3. Accounting Changes In June 1998, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standard ("SFAS") No. 133, "Accounting for Derivative Instruments and Hedging Activities." This statement establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. The Company is required to adopt this statement effective January 1, 2001. SFAS No. 133 will require the Company to record all derivatives on the balance sheet at fair value. Changes in derivative fair value will either be recognized in earnings as offsets to the changes in fair value of related hedged assets, liabilities, and firm commitments or, for forecasted transactions, deferred and recorded as a component of comprehensive income until the hedged transactions occur and are recognized in earnings. The ineffective portion of a hedging derivative's change in fair value will be recognized in earnings immediately. The Company is currently evaluating when it will adopt this standard and the impact of the standard on the Company. The impact of SFAS No. 133 will depend on a variety of factors, including the future level of hedging activity, the types of hedging instruments used, and the effectiveness of such instruments. 4. Prepaid Expenses As of December 31, 1999, prepaid expenses consisted of the amounts expended in 1999 for several insurance policies. These amounts are being amortized over the lives of the policies. 5. Cash and Cash Equivalents Restricted for Capital Additions Pursuant to the notes issued by Port Arthur Finance on behalf of the Company, all proceeds from the notes are restricted for use in the construction of new operating units. 6. Other Assets December 31, 1999 -------------- (in thousands) Other Assets consisted of the following: Deferred financing costs........................................ $18,400 Environmental permits........................................... 1,418 P.M.I. long-term crude oil supply agreement..................... 757 ------- $20,575 ======= The Company incurred deferred financing costs of $18.9 million associated with the issuance of the $255.0 million in notes and having entered into the $325.0 million secured construction and term loan facility. Amortization of deferred financing costs for the period May 4, 1999 (inception) to December 31, 1999 was $0.5 million and is included in "Interest and finance costs, net". The P.M.I. long-term crude oil supply agreement and environmental permits were purchased from Clark Refining & Marketing. When the Coker Project is operational, the Company will amortize the costs over the life of the agreements. F-9 7. Long-Term Debt Long-term debt was a follows: December 31, 1999 ------------ (dollars in thousands) Secured Construction and Term Loan Facility........................ $105,000 12 1/2% Senior Secured Notes due January 15, 2009 (12 1/2% Senior Notes)............................................. 255,000 -------- $360,000 ======== The 12 1/2% Senior Notes were issued by Port Arthur Finance in August 1999 on behalf of the Company at par and are secured by substantially all of the assets of the Company. The Company is required to pay a portion of the principal of the notes on a set schedule on each January 15 and July 15, commencing July 15, 2002. The notes are redeemable at the Company's option at any time at a redemption price equal to 100% of principal plus accrued and unpaid interest plus a make-whole premium which is based on the rates of treasury securities with average lives comparable to the average life of the remaining scheduled payments plus 75 basis points. The Company entered into a $325 million secured construction and term loan facility to be provided by commercial banks and institutional lenders. The construction and term loan was split into a Tranche A of $225 million with a term of 7.5 years and a Tranche B of $100 million with a term of 8 years. Under specified circumstances, the aggregate amount of the construction and term loan facility may be reallocated between the tranches with the Company's consent, which may not be unreasonably withheld. In addition, the Company obtained a $75 million secured working capital facility from commercial banks, which banks included some of the same commercial banks that provide the construction and term loan facility. In February 2000, our $75 million secured working capital facility was reduced to $35 million. The $40 million reduction, a portion of which had been outstanding in the form of a letter of credit to P.M.I. Comercio International to secure against a default by us under our long term oil supply agreement, was replaced by an insurance policy under which an affiliate of American International Group agreed to insure P.M.I. Comercio International against our default under the long term oil supply agreement up to a maximum liability of $40 million. This affiliate of American International Group is treated as a bank senior lender under the common security agreement. The 12 1/2% Senior Notes indenture and construction and term loan facility credit agreement contains certain restrictive covenants including limitations on distributions to our owners from our distribution account, limitations on Blackstone disposing of any equity interest in Clark Refining Holdings, limitations on Clark Refining Holdings disposing of any equity interest in Clark Refining & Marketing, the Port Arthur Refinery or the Company and limitation on incurring additional senior debt. The Company was required to provide a debt service reserve arrangement which was provided through an insurance product that will be replaced with a cash funded reserve account from available cash flow from operations. Interest payments are due semiannually on January 15, and July 15, for both the 12 1/2% Senior Notes and the Secured Construction and Term Loan Facility. The scheduled maturities of long-term debt during the next five years are (in millions): 1999, 2000 and 2001--$0; 2002--$5.3; 2003--$15.8; 2004 and thereafter--$338.9. 8. Capital Contributions Receivable In August 1999, Blackstone and Occidental signed capital contribution agreements totaling $135 million. Blackstone agreed to contribute $121.5 million, and Occidental agreed to contribute $13.5 million to the Company. As of December 31, 1999, Blackstone and Occidental contributed approximately $51.4 million and $5.7 million, respectively, of their commitments. The remaining $77.8 million was recorded as contributions receivable. The contractual arrangements with Blackstone and Occidental provide that the aggregate $135 million equity commitment will be funded pro rata with the funding of the notes and bank term debt, so that at F-10 the time of each advance of debt and equity to pay construction costs the amount funded will be approximately 65% debt and 35% equity. It is expected that the entire $135 million equity commitment will be funded by March 2001. The obligations of Blackstone and Occidental to fund their equity commitments are absolute, irrevocable and unconditional so long as a pro rata portion of bank term debt is funded at the same time. The obligation of Blackstone to fund its outstanding equity commitment may be assumed by a third party if Blackstone transfers its equity interest in Clark Refining Holdings to such third party and either (i) such third party is rated investment grade by both S&P and Moody's after giving effect to such transfer or (ii) a majority of lenders under the Secured Construction and Term Loan Facility have consented to such transfer and either a majority of holders of 12 1/2% Senior Notes have consented or the Company has received a ratings reaffirmation from both rating agencies with respect to the 12 1/2% Senior Notes. 9. Interest and Finance Costs, Net Interest and Finance Costs, Net were as follows: For the period May 4 (inception) to December 31, 1999 ----------------- (dollars in thousands) Interest expense.............................................. $ 15,565 Finance expense............................................... 10,658 Capitalized interest.......................................... (13,798) Interest income............................................... (1,670) -------- Interest and Finance Costs, Net............................... $ 10,755 ======== Finance expense included costs related to the Company's working capital facility as well as insurance costs for working capital, a debt service reserve arrangement and a P.M.I. crude oil supply arrangement. 10. Commitments and Contingencies In July 1999, the Company entered into a contract for the engineering, procurement and construction of the Company's Coker Project with Foster Wheeler USA. Under this construction contract, Foster Wheeler USA will continue to engineer, design, procure equipment for, construct, test and oversee startup of the Coker Project and integrate the Coker Project with the Port Arthur refinery of Clark Refining & Marketing, Inc. Under the construction contract, the Company will pay Foster Wheeler USA a fixed price of approximately $544 million of which $157.1 million was credited to the Company for amounts Clark Refining & Marketing had already paid Foster Wheeler USA for work performed on the Coker Project prior to August 1999. The Company purchased this work in progress from Clark Refining & Marketing when the financings were consummated in August 1999. The Company and Foster Wheeler USA have the ability to initiate changes to work under the contract that may effect the final total price paid. Changes in excess of $0.5 million individually or $5.0 million in the aggregate must be approved by the project's independent engineer. The contract has provisions whereby Foster Wheeler will pay the Company up to $145 million in damages for delays in achieving mechanical completion or guaranteed reliability, based on a defined formula. The Company is required to pay Foster Wheeler USA an early completion bonus of up to $6 million if mechanical completion is achieved prior to November 1, 2000. The Company can terminate the contract with Foster Wheeler USA at any time upon written notice, at which time it will be obligated to pay actual project costs to the date of termination, other costs related to demobilizing, canceling subcontractors or withdrawing from the project site. Foster Wheeler USA cannot terminate the contract unless the Company defaults on required payments under the contract. In August 1999, the Company entered into agreements with Clark Refining & Marketing pursuant to which the Company will receive certain operating, maintenance, and other services from Clark Refining & Marketing and will sell, at market prices, the output from the new coking and hydrocracking equipment to Clark Refining & Marketing for further processing into finished products. The Company also entered into agreements under which it will process certain hydrocarbon streams owned by Clark Refining & Marketing. In F-11 addition, the Company entered into lease agreements under which it will lease Clark Refining & Marketing's crude unit, vacuum tower, two distillate hydrotreaters, and a naphtha hydrotreater at the Port Arthur refinery as well as the site where the Company's new processing units are located. The Company will receive and pay compensation at what it believes to approximate fair market value under these agreements. At December 31, 1999, the Company had a net outstanding payable balance of $0.4 million to Clark Refining & Marketing consisting of a payable of $0.5 million for services under these agreements and fees paid by Clark Refining & Marketing on the Company's behalf and a $0.1 million receivable for the overpayment of such services in a prior period. In August 1999, the Company purchased a long-term crude oil supply agreement with PMI from Clark Refining & Marketing for approximately $0.8 million. The contract includes a gross margin support mechanism designed to provide a minimum average coker gross margin over its initial term. Pursuant to the terms of the contract, PMI will supply to the Company Maya crude oil for a price based on published market prices for crude and refined products, as defined in the contract. The contract extends for eight years from the later of the start- up date of the coker, the schedule completion date of January 2001 or the guarantee date of July 2001. The completion date is the date the coker meets prescribed operating performance. If the completion date extends beyond January 2001, the Company must pay P.M.I $400,000 per month for the first six months of delay and $200,000 per month for up to an additional six months of delay thereafter to extend the completion date or they may terminate the contract. The Company may terminate the contract after paying PMI a termination payment of approximately $170,000 per month after August 31, 1998 plus actual damages that PMI has suffered. The Company does not currently anticipate the Coker Project completion date being extended beyond January 2001. In August 1999, the Company entered into an agreement with Air Products and Chemicals, Inc. ("Air Products") to supply the hydrogen needs of the Coker Project. Air Products will also supply steam and electricity to the Company under this agreement. Prices under the contract are based on market prices at the time of the contract, subject to adjustment according to a formula based on inflation indices. Air Products will be required to pay the Company liquidated damages of up to $1.2 million if the plant fails to be ready for commercial operation on or before December 2000 and the Company will be required to pay Air Products liquidated damages of up to $1.2 million if the Company is unable to start-up the coker for initial operations prior to December 2000. The Company does not currently anticipate the Coker Project initial start-up date being extended beyond December 2000. Environmental laws typically provide that the owner or operators, including lessees, of contaminated properties may be held liable for their remediation. Such liability is typically joint and several, which means that any responsible party can be held liable for all remedial costs, and can be imposed regardless of whether the owner or operator caused the contamination. The Port Arthur refinery is located on a contaminated site. Under the 1994 purchase agreement between Clark Refining & Marketing and Chevron Products USA relating to the Port Arthur refinery, Chevron retained environmental remediation obligations regarding pre-closing contamination at over 97% of the refinery site. Clark Refining & Marketing assumed responsibility for any remediation that is required in and under the remaining 3% of the refinery site, which consists of specified areas that extend 25 to 100 feet from active operating units, including soil and groundwater. Clark Refining & Marketing has estimated its liability for remediation of soil and groundwater soil in these areas at $27 million. Chevron is obligated to remediate the contamination is the areas for which it has retained responsibility as and when required by law, in accordance with remediation plans negotiated by Chevron and the applicable federal and state agencies. No part of our Coker Project site is located within the portion of the Port Arthur refinery site for which Chevron retains environmental remediation obligations. We have estimated remedial costs relating to our Coker Project site, which surpasses 50 acres of the total Port Arthur refinery site surface area, at $1.6 million. Clark Refining & Marketing has agreed to retain liability regarding contamination existing at the Coker Project site and has indemnified the Company against such liabilities; therefore, no such liability has been recorded at the Company. However, if Clark Refining & Marketing does not fulfill its remediation obligations, the Company could incur substantial additional costs in remediating the contamination.

F-17 SABINE RIVER HOLDING CORP. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS December 31, 1999 1. Nature of Business Sabine River Holding Corp., a Delaware holding company, (together with its subsidiaries, the "Company") was incorporated in May of 1999. The Company was formed as the 1% general partner of Port Arthur Coker Company L.P. ("Port Arthur Coker Company"), and as the 100% owner of Neches River Holding Corp. ("Neches River"), which is the 99% limited partner of Port Arthur Coker Company. Sabine River is owned 90% by Clark Refining Holdings Inc. ("Clark Refining Holdings") and 10% by Occidental Petroleum Corporation ("Occidental"). After giving effect to anticipated equity contributions to be made in connection with the funding of the project described below, Clark Refining Holdings will be owned, indirectly through subsidiaries, by Blackstone Capital Partners III Merchant Banking Fund L.P. and its affiliates ("Blackstone") with an approximately 82% interest, and by Occidental with an approximately 17% interest. The Company is an affiliate of Clark Refining & Marketing, Inc. ("Clark Refining & Marketing") because Clark Refining Holdings owns 100% of the capital stock of Clark USA, Inc., which in turn owns 100% of the capital stock of Clark Refining & Marketing. Port Arthur Coker Company was formed to construct, own, operate and finance a new 80,000 barrel per stream day delayed coker unit, a 35,000 barrel per stream day hydrocracker and a 417 long tons per day sulfur complex and related assets (the "Coker Project") at the Port Arthur, Texas refinery of an affiliate, Clark Refining & Marketing, Inc. As of the date hereof, Port Arthur Coker Company and its subsidiary have not conducted any operations and are in the development stage. In order to fund the Coker Project, in August 1999 the Port Arthur Coker Company, through a wholly-owned subsidiary, Port Arthur Finance Corp. ("Port Arthur Finance"), issued $255 million in notes, entered into a $325 million secured construction and term loan facility, obtained a $75 million secured working capital facility and entered into equity subscription agreements totaling $135 million (See Note 7 "Long Term Debt"). Port Arthur Finance, a Delaware holding company, was formed on May 4, 1999. Port Arthur Finance's organizational documents only allow it to engage in activities related to issuing notes and borrowing under bank credit facilities in connection with the initial financing of the Port Arthur Coker Company, and remitting the proceeds thereof to the Port Arthur Coker Company. In issuing the notes and borrowing under the bank credit facilities, Port Arthur Finance is acting as an agent of the Port Arthur Coker Company. As a stand alone entity, Sabine River Holding Corp's function consists only as a guarantor of the notes and bank loans issued by Port Arthur Finance Corporation. Sabine River Holding Corp., as a stand alone entity, has no material assets, no liabilities, and no operations. In March 1998, Clark Refining & Marketing announced that it had entered into a long-term crude oil supply agreement with P.M.I. Comercio Internacional, S.A. de C.V. ("PMI"), an affiliate of Petroleos Mexicanos, the Mexican state oil company. The contract provided Clark Refining & Marketing with the foundation necessary to continue developing a project to upgrade its Port Arthur, Texas refinery to process primarily lower-cost, heavy sour crude oil. The project includes the construction of additional coking and hydrocracking capability, and the expansion of crude unit capacity to approximately 250,000 barrels per day. The oil supply agreement with PMI and the construction work-in-progress related to the new processing units were transferred at fair market value to the Company in the third quarter of 1999. In connection with the project, Clark Refining & Marketing will lease certain existing processing units of Clark Refining & Marketing to the Company on fair market terms and, pursuant to this lease, will be obligated to make certain modifications, infrastructure improvements and incur certain development costs during 1999 and 2000 at an estimated cost up to $120 million. To secure this commitment, Clark Refining & Marketing posted a letter of credit in the amount of $97 million at the closing. As of December 31, 1999, Clark Refining & Marketing had expended approximately $51 million towards this commitment. In addition, the Company entered into agreements with Clark Refining & Marketing pursuant to which Clark Refining & Marketing will provide certain operating, maintenance and other services and will purchase the output from the new coking and F-18 hydrocracking equipment for further processing into finished products. The Company also entered into agreements under which the Company will process certain hydrocarbon streams owned by Clark Refining & Marketing. 2. Summary of Significant Accounting Policies Principles of Consolidation The consolidated financial statements include the accounts of the Company's wholly-owned subsidiary Neches River, and through Neches River's 99% and the Company's 1% ownership of Port Arthur Coker Company, 100% of Port Arthur Finance Corp and Port Arthur Coker Company. All significant intercompany transactions have been eliminated from the consolidated financial statements. 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 disclosure of contingent assets and liabilities at the dates of financial statements and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimates. Cash and cash equivalents The Company considers all highly liquid investments, such as time deposits, money market instruments, commercial paper and United States and foreign government securities, purchased with an original maturity of three months or less, to be cash equivalents. Cash and cash equivalents as of December 31, 1999 approximated fair value. Construction in Progress All additions are recorded at cost and are currently included in Construction in Progress because the Coker Project is under construction. When the assets are in operation, depreciation of plant and equipment will be computed using the straight-line method over the estimated useful lives of the assets or group of assets. The Company capitalizes the interest cost associated with major construction projects based on the effective interest rate on aggregate borrowings applied to expenditures from date of project inception to start-up. Expenditures for maintenance and repairs are expensed. Major replacements and additions are capitalized. Gains and losses on assets depreciated on an individual basis are reflected in the results from operations. The Company reviews long-lived assets for impairments whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Environmental Costs Environmental liabilities are recorded when environmental assessments and/or remedial efforts are probable and can be reasonably estimated. Environmental expenditures are expensed or capitalized depending upon their future economic benefit. Costs that improve a property as compared with the condition of the property when originally constructed or acquired and costs that prevent future environmental contamination are capitalized. Costs that return a property to its condition at the time of acquisition or original construction are expensed. F-19 Income Taxes Sabine River and Neches River file a consolidated U.S. federal income tax return with Clark Refining Holdings, Inc. but compute their provisions on a separate company basis. Deferred taxes are classified as current or noncurrent depending on the classification of the assets and liabilities to which the temporary differences relate. Deferred taxes arising from temporary differences that are not related to a specific asset or liability are classified as current or noncurrent depending on the periods in which the temporary differences are expected to reverse. Sabine River and Neches River record a valuation allowance when necessary to reduce the net deferred tax asset to an amount expected to be realized. As of December 31, 1999, the valuation allowance of the Company reduced the net deferred tax asset to zero. In calculating the valuation allowance, the Company assumed as future taxable income only future reversals of existing taxable temporary differences and available tax planning strategies. Port Arthur Coker Company is classified as a partnership for U.S. federal income tax purposes and, accordingly, does not pay federal income tax. Port Arthur Coker Company files a U.S. partnership return of income and its taxable income or loss flows through to its partners who report and are taxed on their distributive shares of such taxable income or loss. Accordingly, no federal income taxes have been provided by Port Arthur Coker Company. Port Arthur Finance files a separate U.S. federal income tax return and computes its provision on a separate company basis. Deferred taxes are classified as current or noncurrent depending on the classification of the assets and liabilities to which the temporary differences relate. Deferred taxes arising from temporary differences that are not related to a specific asset or liability are classified as current or noncurrent depending on the periods in which the temporary differences are expected to reverse. 3. Accounting Changes In June 1998, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standard ("SFAS") No. 133, "Accounting for Derivative Instruments and Hedging Activities." This statement establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. The Company is required to adopt this statement effective January 1, 2001. SFAS No. 133 will require the Company to record all derivatives on the balance sheet at fair value. Changes in derivative fair value will either be recognized in earnings as offsets to the changes in fair value of related hedged assets, liabilities, and firm commitments or, for forecasted transactions, deferred and recorded as a component of comprehensive income until the hedged transactions occur and are recognized in earnings. The ineffective portion of a hedging derivative's change in fair value will be recognized in earnings immediately. The Company is currently evaluating when it will adopt this standard and the impact of the standard on the Company. The impact of SFAS No. 133 will depend on a variety of factors, including the future level of hedging activity, the types of hedging instruments used, and the effectiveness of such instruments. 4. Prepaid Expenses and Other Current Assets As of December 31, 1999, prepaid expenses consisted of the amounts expended in 1999 for several insurance policies. These amounts are being amortized over the lives of the policies. 5. Cash and Cash Equivalents Restricted for Capital Additions Pursuant to the notes issued by Port Arthur Finance on behalf of the Company, all proceeds from the notes are restricted for use in the construction of new operating units. F-20 6. Other Assets Other assets consisted of the following: December 31, 1999 -------------- (in thousands) Deferred financing costs................................... $ 18,400 Environmental permits...................................... 1,418 PMI long term crude oil supply agreement................... 757 -------- $ 20,575 ======== The Company incurred deferred financing costs of $18.9 million associated with the issuance of the $255.0 million in notes and having entered into the $325.0 million secured construction and term loan facility. Amortization of deferred financing costs for the period May 4, 1999 (inception) to December 31, 1999 was $0.5 million and is included in "Interest and finance cost, net". The PMI long term crude supply agreement and environmental permits were purchased from Clark Refining & Marketing. When the Coker Project is operational, the Company will amortize the costs over the life of the agreements. 7. Long-Term Debt December 31, 1999 -------------- (in thousands) Secured Construction and Term Loan Facility................ $ 105,000 12 1/2% Senior Secured Notes due January 15, 2009 (12 1/2% Senior Notes)..................................... 255,000 --------- $ 360,000 ========= The 12% Senior Notes were issued by Port Arthur Finance in August 1999 on behalf of the Company at par and are secured by substantially all of the assets of the Company. The Company is required to pay a portion of the principal of the notes on a set schedule on each January 15 and July 15, commencing July 15, 2002. The notes are redeemable at the Company's option at any time at a redemption price equal to 100% of principal plus accrued and unpaid interest plus a make-whole premium which is based on the rates of treasury securities with average lives comparable to the average life of the remaining scheduled payments plus 75 basis points. The Company has entered into a $325 million secured construction and term loan facility to be provided by commercial banks and institutional lenders. The construction and term loan is split into a Tranche A of $225 million with a term of 7.5 years and a Tranche B of $100 million with a term of 8 years. Under specified circumstances, the aggregate amount of the construction and term loan facility may be reallocated between the tranches with the Company's consent, which may not be unreasonably withheld. In addition, the Company has obtained a $75 million secured working capital facility from commercial banks, which banks include some of the same commercial banks that provide the construction and term loan facility. In February 2000, our $75 million secured working capital facility was reduced to $35 million. The $40 million reduction, a portion of which had been outstanding in the form of a letter of credit to PMI to secure against a default by us under our long-term oil supply agreement, was replaced by an insurance policy under which an affiliate of American International Group agreed to insure PMI against our default under the long term oil supply agreement up to a maximum liability of $40 million. This affiliate of American International Group is treated as a bank senior lender under the common security agreement. The 12 1/2% Senior Notes indenture and construction and term loan facility credit agreement contains certain restrictive covenants including limitations on distributions to our owners from our distribution account, F-21 limitations on Blackstone disposing of any equity interest in Clark Refining Holdings, limitations on Clark Refining Holdings disposing of any equity interest in Clark Refining & Marketing, the Port Arthur Refinery or the Company and limitation on incurring additional senior debt. The Company was required to provide a debt service reserve arrangement which was provided through an insurance product that will be replaced with a cash funded reserve account from available cash flow from operations. Interest payments are due semiannually on Janaury 15, and July 15, for both the 12 % Senior Notes and the Secured Construction and Term Loan Facility. The scheduled maturities of long-term debt during the next five years are (in millions): 1999, 2000 and 2001--$0; 2002--$5.3; 2003--$15.8; 2004 and thereafter--$338.9. 8. Capital Contribution Receivable In August 1999, Blackstone and Occidental signed capital contribution agreements totaling $135 million. Blackstone agreed to contribute $121.5 million, and Occidental agreed to contribute $13.5 million to the Company. As of December 31, 1999, Blackstone and Occidental contributed approximately $51.4 million and $5.7 million, respectively, of their commitments. The remaining $77.8 million is recorded as a contribution receivable. The contractual arrangements with Blackstone and Occidental provide that the aggregate $135 million equity commitment will be funded pro rata with the funding of the notes and bank term debt, so that at the time of each advance of debt and equity to pay construction costs the amount funded will be approximately 65% debt and 35% equity. It is expected that the entire $135 million equity commitment will be funded by March 2001. The obligations of Blackstone and Occidental to fund their equity commitments are absolute, irrevocable and unconditional so long as a pro rata portion of bank term debt is funded at the same time. The obligation of Blackstone to fund its outstanding equity commitment may be assumed by a third party if Blackstone transfers its equity interest in Clark Refining Holdings to such third party and either (i) such third party is rated investment grade by both S&P and Moody's after giving effect to such transfer or (ii) a majority of lenders under the Secured Construction and Term Loan Facility have consented to such transfer and either a majority of holders of 12 1/2% Senior Notes have consented or the Company has received a ratings reaffirmation from both rating agencies with respect to the 12 1/2% Senior Notes. 9. Interest and Finance Costs, Net Interest and Finance Costs, Net were as follows: For the period May 4 (inception) to December 31, 1999 ----------------- (dollars in thousands) Interest expense........................................ $ 15,565 Finance expense......................................... 10,658 Capitalized interest.................................... (13,798) Interest income......................................... (1,670) -------- Interest and Finance Costs, Net......................... $ 10,755 ======== Finance expense included costs related to the Company's working capital facility as well as insurance costs for working capital, a debt service reserve arrangement and the PMI crude oil supply arrangement. 10. Commitments and Contingencies In July 1999, the Company entered into a contract for the engineering, procurement and construction of the Company's Coker Project with Foster Wheeler USA. Under this construction contract, Foster Wheeler USA will continue to engineer, design, procure equipment for, construct, test and oversee startup of the Coker Project and integrate the Coker Project with the Port Arthur refinery of Clark Refining & Marketing, Inc. Under F-22 the construction contract, the Company will pay Foster Wheeler USA a fixed price of approximately $544 million of which $157.1 million was credited to the Company for amounts Clark Refining & Marketing had already paid Foster Wheeler USA for work performed on the Coker Project prior to August 1999. The Company purchased this work in progress from Clark Refining & Marketing when the financings were consummated in August 1999. The Company and Foster Wheeler USA have the ability to initiate changes to work under the contract that may effect the final total price paid. Changes in excess of $0.5 million individually or $5.0 million in the aggregate must be approved by the project's independent engineer. The contract has provisions whereby Foster Wheeler will pay the Company up to $145 million in damages for delays in achieving mechanical completion or guaranteed reliability, based on a defined formula. The Company is required to pay Foster Wheeler USA an early completion bonus of up to $6 million if mechanical completion is achieved prior to November 1, 2000. The Company can terminate the contract with Foster Wheeler USA at any time upon written notice, at which time it will be obligated to pay actual project costs to the date of termination, other costs related to demobilizing, canceling subcontractors or withdrawing from the project site. Foster Wheeler USA cannot terminate the contract unless the Company defaults on required payments under the contract. In August 1999, the Company entered into agreements with Clark Refining & Marketing pursuant to which the Company will receive certain operating, maintenance, and other services from Clark Refining & Marketing and will sell, at market prices, the output from the new coking and hydrocracking equipment to Clark Refining & Marketing for further processing into finished products. The Company also entered into agreements under which it will process certain hydrocarbon streams owned by Clark Refining & Marketing. In addition, the Company entered into lease agreements under which it will lease Clark Refining & Marketing's crude unit, vacuum tower, two distillate hydrotreaters, and a naphtha hydrotreater at the Port Arthur refinery as well as the site where the Company's new processing units are located. The Company will receive and pay compensation at what it believes to approximate fair market value under these agreements. At December 31, 1999, the Company had a net outstanding payable balance of $0.4 million to Clark Refining & Marketing consisting of a payable of $0.5 million for services under these agreements and fees paid by Clark Refining & Marketing on the Company's behalf and a $0.1 million receivable for the overpayment of such services in a prior period. In August 1999, the Company purchased a long-term crude oil supply agreement with PMI from Clark Refining & Marketing for approximately $0.8 million. The contract includes a gross margin support mechanism designed to provide a minimum average coker gross margin over its initial term. Pursuant to the terms of the contract, PMI will supply to the Company Maya crude oil for a price based on published market prices for crude and refined products, as defined in the contract. The contract extends for eight years from the later of the start- up date of the coker, the schedule completion date of January 2001 or the guarantee date of July 2001. The completion date is the date the coker meets prescribed operating performance. If the completion date extends beyond January 2001, the Company must pay P.M.I $400,000 per month for the first six months of delay and $200,000 per month for up to an additional six months of delay thereafter to extend the completion date or they may terminate the contract. The Company may terminate the contract after paying PMI a termination payment of approximately $170,000 per month after August 31, 1998 plus actual damages that PMI has suffered. The Company does not currently anticipate the Coker Project completion date being extended beyond January 2001. In August 1999, the Company entered into an agreement with Air Products and Chemicals, Inc. ("Air Products") to supply the hydrogen needs of the Coker Project. Air Products will also supply steam and electricity to the Company under this agreement. Prices under the contract are based on market prices at the time of the contract, subject to adjustment according to a formula based on inflation indices. Air Products will be required to pay the Company liquidated damages of up to $1.2 million if the plant fails to be ready for commercial operation on or before December 2000 and the Company will be required to pay Air Products liquidated damages of up to $1.2 million if the Company is unable to start-up the coker for initial operations prior to December 2000. The Company does not currently anticipate the Coker Project initial start-up date being extended beyond December 2000. F-23 Environmental laws typically provide that the owner or operators, including lessees, of contaminated properties may be held liable for their remediation. Such liability is typically joint and several, which means that any responsible party can be held liable for all remedial costs, and can be imposed regardless of whether the owner or operator caused the contamination. The Port Arthur refinery is located on a contaminated site. Under the 1994 purchase agreement between Clark Refining & Marketing and Chevron Products USA relating to the Port Arthur refinery, Chevron retained environmental remediation obligations regarding pre-closing contamination at over 97% of the refinery site. Clark Refining & Marketing assumed responsibility for any remediation that is required in and under the remaining 3% of the refinery site, which consists of specified areas that extend 25 to 100 feet from active operating units, including soil and groundwater. Clark Refining & Marketing has estimated its liability for remediation of soil and groundwater soil in these areas at $27 million. Chevron is obligated to remediate the contamination is the areas for which it has retained responsibility as and when required by law, in accordance with remediation plans negotiated by Chevron and the applicable federal and state agencies. No part of our Coker Project site is located within the portion of the Port Arthur refinery site for which Chevron retains environmental remediation obligations. We have estimated remedial costs relating to our Coker Project site, which surpasses 50 acres of the total Port Arthur refinery site surface area, at $1.6 million. Clark Refining & Marketing has agreed to retain liability regarding contamination existing at the Coker Project site and has indemnified the Company against such liabilities; therefore, no such liability has been recorded at the Company. However, if Clark Refining & Marketing does not fulfill its remediation obligations, the Company could incur substantial additional costs in remediating the contamination.

INTRODUCTION Purvin & Gertz, Inc. ("PGI") has been retained as Independent Engineer ("IE") to review certain aspects of the Port Arthur Coker Company L.P. heavy oil upgrade project as defined herein. The heavy oil upgrade project is to be constructed at the Clark Refining & Marketing, Inc. ("Clark") refinery located at Port Arthur, Texas. This report has been prepared by PGI on behalf of financing parties and lenders of senior debt (collectively, the "Financing Parties") to a newly formed limited partnership, the Port Arthur Coker Company L.P. ("PACC") and its wholly owned subsidiary, Port Arthur Finance Corp. PGI understands that this report will be provided to certain insurance companies and included as an appendix to preliminary and final offering circulars, bank syndicate information memoranda and prospectuses relating to the offer and sale of senior debt securities of the PACC and its affiliates. PGI consents to this report being so included as an appendix to such preliminary and final offering circulars, bank syndicate information memoranda and prospectuses, subject to the limitations expressed therein. Certain information contained in this report is covered under confidentiality agreements between Clark and third parties. PGI conducted this analysis and prepared this report utilizing reasonable care and skill in applying methods of analysis consistent with normal industry practice. All results are based on information available at the time of review. Changes in factors upon which the review is based could affect the results. Forecasts are inherently uncertain because of events or combinations of events that cannot reasonably be foreseen including the actions of government, individuals, third parties and competitors. NO IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE SHALL APPLY. PGI has not addressed potential year 2000 recognition problems in this analysis and the results assume zero impact from year 2000 recognition problems. Some of the information on which this report is based has been provided by the Upgrade Project participants, including Clark. PGI has utilized such information without verification unless specifically noted. PGI accepts no liability for errors or inaccuracies in information provided by others. All defined terms are either defined in this document, in the Definitions to the Intercompany Agreements (as defined herein), or in the EPC Contract (as defined herein). PROJECT OVERVIEW An 80,000 barrel per stream day ("bpsd") delayed coker, a 35,000 bpsd vacuum gas oil ("VGO") hydrocracker, a 417 long tons per day ("LTD") sulfur recovery unit ("SRU"), revamps to the existing crude unit, vacuum unit, hydrotreaters and certain offsites (the "Upgrade Project") will be constructed at Clark's Port Arthur, Texas refinery (the "Refinery") in order to add additional heavy sour crude oil, primarily Mexican Maya, processing capabilities. PACC will be established in order to construct, own and operate the coker, hydrocracker, SRU and certain offsites. PACC will also lease 100% of Clark's existing crude unit, vacuum unit, and three hydrotreaters (naphtha, jet and diesel), and will have access to all necessary Clark-owned common facilities under the Ancillary Equipment Site Lease And Easement Agreement and the Coker Complex Ground Lease And Blanket Easement Agreement (all described herein). (See Figure I-1 for listing of major facilities included in the scope of the Upgrade Project). Clark will also provide other services and utilities to PACC under the Services and Supply Agreement (as described herein) and will purchase all products produced by PACC under the Product Purchase Agreement (described herein). The Ancillary Equipment Site Lease And Easement Agreement, the Coker Complex Ground Lease And Blanket Easement Agreement, the Services and Supply Agreement and the Product Purchase Agreement will be referred to as a group throughout this report as "Intercompany Agreements". PACC will also be the assignee of the crude oil supply agreement ("PMI Contract"--see description herein) which provides for a minimum supply of Maya crude oil and contains a mechanism for stabilizing coker gross margin. PACC will enter into a fixed price turn-key ("LSTK") engineering, procurement and construction contract (the "EPC Contract") with Foster Wheeler USA B-1 Corporation ("Foster Wheeler") in order to construct the new units ("PACC Project"). Clark will enter into a separate "cost-plus" reimbursable contract with Foster Wheeler (the "Clark EPC Contract") for the renovation and upgrade of certain existing Refinery units and offsites required for the PACC Project ("Clark Project"). Air Products and Chemicals, Inc. ("APCI") will design, construct and operate a hydrogen plant on the Refinery site to supply PACC's hydrogen requirements secured by a long term contract between PACC and APCI ("Hydrogen Contract"). Clark will also contract for steam and electricity to be produced at the APCI hydrogen plant. [Chart of Figure I-1 Major Facilities Included in Upgrade Project] SCOPE OF REVIEW PGI has reviewed certain technical, environmental and economic aspects of the Upgrade Project as listed below: . Upgrade Project design basis . PACC Project integration with Clark Project . PACC Project and Clark Project cost estimates and construction schedules . Construction and procurement strategy . Handling, storage and disposal of coke . Principal Upgrade Project participant capabilities . PACC Project charge, yield and operating cost projections . Intercompany Agreements B-2 . Environmental permits and safety data . PACC Project Base Case economic model, sensitivities and stand-alone case . Project contracts and documentation as listed in Appendix A . Hydrogen supply PGI also conducted interviews with key members of the Upgrade Project management team. PGI has also prepared a separate Crude Oil and Refined Product Market Forecast which provides the basis for the crude oil and product prices utilized in PACC economic projections and which confirms that sufficient Maya crude oil will be available to fulfill the supply obligations under the PMI Contract. PGI conducted this analysis and prepared this report utilizing reasonable care and skill in applying methods of analysis consistent with normal industry practice. In the preparation of this report and the opinions expressed, PGI has made certain assumptions with respect to conditions which may exist or events which may occur in the future. All results and conclusions are based on information available at the time of the review. Changes in factors upon which the review is based could affect the results and the conclusions. The principal assumptions and considerations made by PGI in developing the results and conclusions presented in this report include the following: . As IE, PGI has made no determination as to the validity and enforceability of any contract or agreement applicable to the Upgrade Project. However, for purposes of this report, PGI has assumed that all such contracts and agreements will be fully enforceable in accordance with their respective terms and that all parties will comply with the provisions of such contracts and agreements. In addition, PGI has assumed that the Upgrade Project has or will comply with all regulations that may be applicable thereto. . As IE, PGI has reviewed the design practices and cost estimating methods employed for the Upgrade Project to determine if industry standards and practices were followed; however, PGI has not re-performed design or cost estimate calculations. PGI's review has been conducted utilizing reasonable care and skill in accordance with customary industry standards and provides a reasonable basis for the conclusions contained in this report. . Foster Wheeler, as the Upgrade Project contractor and Clark, as operator, will construct, manage operation of and maintain the Upgrade Project in accordance with good industry standards and practices. . Clark and PACC will make all required renewals and replacements in a timely manner, and will not operate equipment to cause it to exceed the equipment manufacturer's recommended maximum ratings for extended periods of time. B-3 II. PROJECT PARTICIPANTS [Chart of Figure II-1 Project Participants] CLARK REFINING HOLDINGS INC. Clark Refining Holdings Inc. ("Clark Holdings") is principally owned by Blackstone Capital Partners III Merchant Banking Fund L.P. and its affiliates ("Blackstone") and Occidental Petroleum Corporation ("Oxy"). The company's operations include refining, marketing, and supply and transportation of petroleum products. Clark Holdings, through its 100% wholly owned operating subsidiary Clark Refining & Marketing, Inc. owns and operates three Midwest oil refineries and the Port Arthur oil refinery. The Midwest refineries are located in Lima, Ohio (capacity 170,000 bpsd), Blue Island, Illinois (capacity 80,000 bpsd), and Hartford, Illinois (capacity 65,000 bpsd). The Gulf Coast refinery is located in Port Arthur, Texas (capacity 232,000 bpsd). The company is currently the fifth largest independent refiner in the U.S. and markets gasoline, diesel fuel and other petroleum products on a wholesale unbranded basis. On July 8, 1999, Clark Holdings announced that it had disposed of its retail marketing assets for cash proceeds of $230 million. Clark Holdings is experienced in undertaking capital projects. In 1998, the company had capital expenditures of approximately $160 million. The company has executed two large scale refinery acquisition projects in the last four years totaling over $440 million. In addition, the company has extensive experience in B-4 operating coker units. The Lima, Hartford and Port Arthur refineries all have operating coker units with a combined capacity of 70,000 bpsd. FOSTER WHEELER USA CORPORATION Foster Wheeler designs, engineers and constructs petroleum, chemical, petrochemical and alternative-fuels facilities. In addition, Foster Wheeler owns and licenses patents, trademarks and proprietary knowledge which are used in each of its industry groups. Foster Wheeler Corporation, the parent of Foster Wheeler, had revenues totaling $4,597 million and total assets of $3,495 million for the year ending December 31, 1998, and has approximately 11,000 employees. Foster Wheeler has designed and built over 100 cokers, representing 80% of the existing cokers in the world. These include many comparable projects that are in various phases of completion such as: .Shell--Martinez, Norco, Deer Park, Moerdijk, and Buenos Aires refineries .PEMEX--Madero, Minatitlan, Salina Cruz, and Cadereyta refineries .Koch--Corpus Christi refinery .Chevron--Salt Lake City, and Pascagoula refineries .Exxon/Mobil--Baton Rouge, and Paulsboro refineries In addition to the construction of coker units, Foster Wheeler also has extensive experience in building hydrocracking units. Since the 1960s, the company has executed over 30 hydrocracker projects. During the last ten years, the company has performed 39 engineering, procurement and construction projects, and currently has 3 Orinoco Belt extra-heavy oil upgrade projects in engineering stages. PGI views Foster Wheeler as the industry leader in the design and construction of coker units, and believes the company is the well qualified choice for the execution of the Upgrade Project. AIR PRODUCTS AND CHEMICALS INC. APCI is a multinational corporation which produces industrial gases, chemicals and energy/environmental systems. The company has developed expertise in supplying industrial gases for over 50 years. APCI operates and maintains over 300 air separation facilities worldwide.

Since 1992, APCI has been allied with Kinetics Technology International ("KTI") a leading supplier of hydrogen plants to the refinery industry. The APCI/KTI alliance has constructed and continues to operate several onsite hydrogen plants for refineries similar to the facility proposed for Clark. PGI believes that APCI is well qualified to construct and operate the proposed hydrogen plant which will be capable of supplying the Upgrade Project with its hydrogen requirements and, in addition, electricity and steam. PETROLEOS MEXICANOS/P.M.I. COMERCIO INTERNACIONAL Petroleos Mexicanos ("Pemex") is the national oil company of Mexico and one of the world's largest producers of crude oil and natural gas with 1997 revenues in excess of $30 billion. Pemex is the sole developer of Mexico's crude oil and natural gas reserves, which in the aggregate rank in the top ten accumulations of known hydrocarbons in the world and have an estimated current reserve life of approximately 40 years. Pemex is also a major manufacturer and distributor of refined petroleum products and basic petrochemical feedstocks. The company owns and operates six domestic refineries and owns a 50% interest in the Shell Deer Park B-5 Refining Company in Texas. As a wholly owned entity of the Mexican state, Pemex is a major contributor to the country's federal budget. In 1997, Pemex's federal taxes and duties represented 36.6% of the total federal budget. P.M.I. Comercio Internacional, S.A. de C.V. ("PMI") which is 93% owned by Pemex and 7% owned by branches of the Federal Government of Mexico, is the international trading arm of Pemex responsible for all exports. Pemex produces three primary types of crude oil for export: (i) Isthmus, a light crude oil, 33.6(degrees) API density and 1.3 weight % sulfur, (ii) Maya, heavy crude oil, 22(degrees) API density and 3.3 weight % sulfur, and (iii) Olmeca, a very light crude oil, 39.3(degrees) API density and 0.8 weight % sulfur. The U.S. is the dominant export market for Pemex with 80% of total exports in 1998. Maya crude oil exports totaled 1 million barrels per day in 1998 and are expected to increase throughout the forecast period. Pemex through PMI has been actively seeking to expand the otherwise limited market for its increasing reserves of Maya crude oil by offering attractive long term crude oil supply agreements. The U.S. has been the targeted market for these agreements since Pemex realizes the highest value for its crude oil in the U.S. market due to lower transportation costs. PMI has signed long term supply agreements with Clark, Coastal Corp., Deer Park Refining L.P., Marathon Ashland Petroleum and Exxon Corp., of which Clark's is one of the largest. B-6 III. CONCLUSIONS In PGI's opinion, the Upgrade Project will transform the Refinery into one of the top five refineries on the Gulf Coast in terms of competitiveness and heavy crude oil conversion capacity. The investment in the Upgrade Project is consistent with Clark Holdings overall strategy and will allow Clark to further improve its market position in a very competitive environment. Based on our review of the Upgrade Project, PGI has reached the following technical, commercial/marketing and financial conclusions: TECHNICAL 1. The design of the major new units to be installed at the Refinery, specifically the delayed coker and the hydrocracker process units, are based on licensed technology that is well established and commercially proven. Clark has obtained and will transfer to PACC a process license from Chevron Research and Technology Company ("Chevron"), a subsidiary of Chevron USA, for the hydrocracking technology and will obtain the Foster Wheeler delayed coking technology as part of the EPC Contract. The size and configuration of the new process units should integrate well with the Refinery. 2. The Upgrade Project capital cost estimate provided by Foster Wheeler and Clark of $636 million for the construction of new units, offsites, and revamps is reasonable and includes all relevant items based on PGI's review of the estimate. The contingency and escalation allowance included in the estimate is adequate at this stage of the Upgrade Project. The total Upgrade Project cost including owner's costs, additional contingency, financing costs and interest during construction is $833 million. 3. The Upgrade Project schedule of 31 months from April 1998 to mechanical completion at November 1, 2000 is achievable. Field construction work in the areas of site preparation, piling, foundations, and structural are currently underway. As of June 1999, 98% of the major equipment has been placed on order and 70% of the final design and engineering work has been completed, and civil construction is very advanced. 4. Clark obtained an umbrella flexible air emissions permit which was amended as of August 31, 1998 to allow construction and operation of the Upgrade Project. In May 1999, the PACC units were removed from Clark's flexible permit and a new permit for such units was issued to PACC. PACC will have all permits required to construct, own and operate the PACC Project, including the stand-alone case, as needed. PACC also obtained a standby permit in July 1999 to allow PACC to have its own permit to cover the entire Refinery, including the Ancillary Equipment, if it is needed in the event of a Clark bankruptcy or otherwise. The wastewater treatment facility is a state of the art design and will be able to accommodate the effluent from the Upgrade Project in compliance with environmental regulations and requirements. Solid and hazardous wastes are reported to be handled, stored and transported according to the required regulations and do not present any non-compliance issues. 5. There are no apparent site conditions including known underground obstructions or contamination that would lead to major cost overruns. All of the major site excavation has been completed. 6. The Upgrade Project will have a useful life of at least twenty years extending well beyond the term of the debt financing. 7. Foster Wheeler is a reputable engineering contractor experienced in designing and constructing refining and petrochemical facilities. In addition, PGI believes that Foster Wheeler is well qualified for the proposed assignment and has the resources and financial strength necessary to fulfill their obligations under the EPC Contract and Clark EPC Contract. 8. The EPC Contract specifies a fixed price ($544 million) and a firm mechanical completion date. The EPC Contract terms and conditions are very specific in protecting price, efficiencies and completion B-7 date, and incorporate substantial penalties in the event of schedule delays. In addition, Foster Wheeler has indicated that the EPC Contract contains a contingency amount of $35 million. In PGI's opinion the EPC Contract is favorable to PACC, suitable for this type of financing, and provides adequate protection to PACC for cost overruns, completion risk, integration risk and inefficiencies. 9. No owners of PACC or Clark will provide a completion guarantee for the Upgrade Project. Foster Wheeler will be responsible for satisfying the required performance and reliability tests including meeting the contractual capacity and efficiency process guarantees. Tests have been structured to validate the cash flow availability in order to support the anticipated debt service capacity and if not, to cause Foster Wheeler to buy down the debt to adjust it according to the reduced debt capacity. The liquidated damages cap of $145 million represents up to $70 million of delay damages and up to $75 million of buydown damages for inefficiencies and is adequate for this type of project. PGI will monitor the construction progress and funds disbursements for the EPC Contract and witness and approve the performance/reliability tests. 10. The crude unit and hydrotreater modifications, and other offsites and utilities will be undertaken by Foster Wheeler under the Clark EPC Contract. These types of modifications are a group of relatively routine small refinery projects normally carried out during turnarounds or during refinery operation that Clark and PGI expect to cost $92 million. The major components of Clark's responsibility, the crude unit revamp and interconnecting piping, are planned to be complete and in operation at least six months prior to the EPC Contract Target Mechanical Completion Date. PGI believes that the Clark Project will not present a major risk to the successful startup, operation and integration of the PACC Project. 11. Clark is an experienced fuels refinery operator currently processing Maya crude oil and operating two existing cokers at the Refinery. PGI believes that Clark is well qualified to manage operations at the Refinery. 12. The newly constructed units can be reasonably expected to achieve the on-stream factors in the Base Case projections. The Base Case projections include a reduced on-stream factor through 2000 to reflect startup and achieving a steady operation. 13. The crude import infrastructure at Clark's facilities and at Sun Pipe Line Company's ("Sun") Nederland terminal and connecting pipelines to the Refinery facilities are adequate to support the volumes of imported Maya and other crude oils contemplated for the Upgrade Project's operation. Several pipeline and terminal alternatives also exist to deliver crude oil to the Refinery if required. 14. A new hydrogen plant will be constructed at the Refinery by APCI in support of both PACC and Clark's hydrogen requirements. The capacity of the hydrogen plant will be in excess of the Upgrade Project's requirements and an amount equivalent to approximately 69% of the total Hydrogen Contract volume will be sold under contract to PACC on a "take and pay, if delivered" basis. Clark will also contract for steam and electricity to be produced at the APCI plant. PGI believes that APCI is a reliable hydrogen producer and that the plant will be constructed in a timely manner and that it will produce the required hydrogen and utilities at the contract specifications. Approximately 50% of the required hydrogen can be supplied by APCI via pipeline as a backup, if necessary. COMMERCIAL AND MARKETING 1. Clark has entered into the PMI Contract with PMI that will be assigned to PACC simultaneously with the close of the PACC financing. The PMI Contract was designed to minimize the effect of adverse refining cycles, thereby establishing more stable cash flow for PACC. In order to effect stable cash flows, the PMI Contract contains a formula that is intended to be an approximation for coker gross margin and is designed to provide for a minimum average coker gross margin for the first eight years B-8 following completion of the Upgrade Project. The mechanism, which is more fully described in the Project Contracts section, guarantees an average minimum $15.00 per barrel Differential formula related to coker gross margin via price adjustments on Maya crude oil. If the Differential formula amount is calculated over the August 1987 to December 1998 period and regressed against the historical WTI/Maya differential, the mathematical results implies that the $15/bbl is equivalent to the WTI/Maya differential of $5.94/bbl. This is $0.24/bbl above the historical average WTI/Maya differential of $5.70/bbl over the same period. PGI has reviewed the PMI Contract and believes the mechanism serves as a suitable method of stabilizing coker gross margin fluctuations. 2. Clark will offtake all the intermediate and final products produced by PACC and will provide services to PACC on a routine contractual basis. Clark will be able to incorporate the products from PACC into the Refinery and has considerable experience in selling finished products into the Gulf Coast market. The volume of incremental finished products produced by the Refinery as a result of the operation of the Upgrade Project (a 15% increase) will be minor in proportion to the entire Gulf Coast market (about 1/2% of current market) and its growth forecast and PGI does not expect such volume to impact the market. The product offtake, operation, maintenance and other services are provided under Intercompany Agreements between Clark and PACC (see Project Contracts for description). In PGI's opinion, the Intercompany Agreements will transact products and services that are priced to reflect arms-length mechanisms and market-based prices and contain fair market terms. 3. Based on PGI's analysis of the worldwide heavy oil supply and demand fundamentals and plans and objectives stated by Pemex and PDVSA, PGI forecasts that heavy crude production will continue to increase through the term of the PACC financing. The crude oil heavy/light differential (defined as WTI Cushing minus Maya FOB Mexico) is forecast to average $6.00 per barrel or above in constant 1999 dollars over the same period. This is equivalent to a $15.16 per barrel coker gross margin as defined by the Differential formula in the PMI Contract. This forecast is consistent with the expectation that coker projects will continue to develop in an orderly fashion in line with the expected heavy crude oil production increases. 4. PGI believes that PEMEX/PMI have sufficient Maya crude oil reserves to fulfill the supply obligation under the PMI Contract. PGI believes the risk of diversion of Maya crude oil away from PACC is minimal because: (i) Mexico is significantly increasing production of Maya; (ii) the number of other sour crude refineries able to process Maya are very limited; (iii) the demand for heavy crude oil outside the U.S. is small and PGI does not expect demand to change during the forecast period; and (iv) the netback for heavy crude oil shipments to Europe or Asia is low relative to U.S. Gulf Coast deliveries. 5. While the Upgrade Project is designed to process Maya crude oil as its primary feedstock, it will have the flexibility of processing other similar quality heavy sour crude oils and will be able to achieve essentially equivalent economics to the Base Case projections (the "Base Case") with minimal changes to configuration excluding any benefits of the coker gross margin guarantee in the PMI Contract. 6. The shutdown of the Refinery is, in the opinion of PGI, an extremely remote possibility due to its competitiveness post-completion of the Upgrade Project. 7. The terms of each of the Product Purchase Agreement, the Services and Supply Agreement, the Ground Lease and Blanket Easement Agreement and the Ancillary Equipment Site Lease and Easement Agreement are as favorable to Clark and to PACC, in all material respects, as terms that would be obtainable at this time for a comparable transaction or series of similar transactions in arm's length dealings with a person who is not an affiliate. In the opinion of PGI, payments to be made by Clark to PACC under the Product Purchase Agreement and the Services and Supply Agreement are fair consideration for the products acquired or services received. B-9 8. The consideration PACC will pay Clark for PACC's assumption of the PMI Contract, PACC's acquisition of work in progress under the construction contract and Clark's reduction of the permissible emissions levels under one of its air emissions permits in order to allow PACC to obtain its air permit is equal to the fair market value of such assets. Clark will receive rental payments under both the Ground Lease and Blanket Easement Agreement and the Ancillary Equipment Site Lease and Easement Agreement equal to the fair market value rental payments of the property leased. FINANCIAL PROJECTIONS 1. The Base Case assumes that the PACC-owned units are operated as part of the Refinery. Assuming a PGI price forecast, the estimated average operating cash flow over the initial 11 year operating period for PACC is approximately $228 million per year and the after-tax cash flows generated by PACC will be sufficient to repay PACC debt obligations (scheduled principal amortization and interest) with minimum and average debt service coverage ratios ("DSCR") of 2.0 and 2.4, respectively. 2. PGI analyzed various sensitivity cases including a backcast (1989- 1998). PGI presents the back cast from 1989-1996 (the "Backcast Case") because the PACC debt has a term of eight years after start-up. PGI concludes that in all cases PACC can comfortably meet its debt service obligations. The PMI Account provides liquidity during low coker margin periods. This can be seen in the Backcast Case with minimum and average DSCRs of almost 1.0 and 2.0 respectively. In 2007 (DSCR of almost 1.0) where the debt service shortfall amounts to $3.0 million, the PMI Account is fully funded with $50 million. In the Backcast Case without the PMI Contract in place, cash flow shortfall amounts to $5.0 million, with a debt service reserve account of $37 million and over $100 million of cash available for debt service. The PMI Account effectively mitigates the timing issue of a delay in receiving discounts after prior period surpluses. When fully funded and combined with the debt service reserve account, these reserve accounts provide approximately 1.25 years of debt service coverage. 3. The proceeds of the total financing combined with the proposed equity should be sufficient to pay the total estimated Upgrade Project cost of $833 million. 4. If the PACC-owned units and the modifications to the Ancillary Equipment are designed, constructed, operated and maintained as currently proposed, PACC should be capable of meeting or exceeding the production projections. 5. The basis for the estimate of PACC's total costs of operating and maintaining the PACC facilities is in accordance with standard industry practice. The operating and maintenance costs set forth in the Base Case projections provide sufficient funds for the operations and maintenance of the PACC facilities consistent with the operating scenarios presented. STAND-ALONE CASE To demonstrate the robustness of the economics of PACC and to ensure that PACC can be operated independently from Clark, PGI developed a stand-alone case that assumes the following: . PACC continues its operations while operations at the rest of the Refinery are discontinued, other than the units PACC owns, is leasing or has a right to use under the Coker Complex Ground Lease. . PACC uses the full capacity of the leased and owned facilities. . A third-party is managing the operation of all PACC leased and owned units for PACC. . PACC continues to purchase crude oil under the PMI Contract. . A third party is marketing all intermediate and finished products on behalf of PACC. . PACC's rights to possession under the Ancillary Equipment Site Lease and Coker Complex Ground Lease remain in effect. B-10 In this regard PGI believes that: 1. From a technical standpoint, PACC could successfully continue to operate in a stand-alone mode given the preceding assumptions. 2. The modifications necessary to achieve stand-alone operation are relatively minor and could be achieved within three months and will cost less than $5 million. 3. The intermediate and finished products produced from a stand-alone operation should be readily marketable based on appropriate discounts for quality to spot market prices to long term off-takers since PACC is located in the most liquid refinery products market in the world. Discounts are applied to naphtha and VGO over a three-year period to account for the market disruption caused by introducing a large volume of intermediate products into the market. 4. Even in this extremely unlikely scenario, PACC is able to service its debt obligations after paying all operating expenses as evidenced by projected minimum and average after tax DSCRs of 1.1 and 1.9, respectively. B-11 IV. DISCUSSION OF FINDINGS PROCESS DESCRIPTION The Refinery is currently configured to process a medium sour crude oil slate as limited by delayed coker and hydrotreating capacity. The design basis of the Upgrade Project is a refinery crude oil throughput of 250,000 bpsd of primarily a heavy sour crude oil slate consisting of up to 210,000 bpsd of Maya and 40,000 bpsd of light opportunity crude which is assumed to be Arab Light in the Base Case. PACC has been established to facilitate the construction of an 80,000 bpsd delayed coker, a 35,000 bpsd VGO hydrocracker, and a 417 LTD sulfur recovery plant. In addition, modifications will be made to existing units throughout the Refinery to enable processing of the heavy crude oil slate. The units to be modified, which will remain under Clark ownership, include the crude/vacuum unit, the distillate hydrotreaters, the naphtha hydrotreater, and the crude oil feed system. Other offsites will also be constructed in support of the Upgrade Project. The simplified block flow diagram in Figure IV-1 below illustrates the interaction of the PACC units and the Clark units. [BLOCK FLOW DIAGRAM] (1) Third party designed, constructed, owned and operated. (2) Includes sour water stripper and amino treated units. (3) Owned by Clark R&M. (4) Purchased by the PACC under the PMI Contract (5) Purchased by Clark and not covered by the PMI Contract B-12 The delayed coker is designed to process 80,000 bpsd of vacuum resid and is equipped with 6 coking drums. The delayed coking unit converts vacuum residue via thermal cracking to lighter more valuable products, namely heavy gas oil which is fed to the hydrocracker, light gas oil which is blended to the distillate pool after further processing, naphtha feed for the reformer, butane/butylene, propane/propylene, and fuel gas. The delayed coker being constructed is a modern Foster Wheeler design incorporating a low operating drum pressure and a low recycle rate. Coke from the unit is currently planned to be loaded by crane into rail cars for sale by PACC to Clark. The VGO hydrocracker is a 2-stage Chevron design with a design operating pressure of 2500 psig. The unit is designed to process 35,000 bpsd of feedstock consisting of coker heavy gas oil, virgin VGO, and light cycle oil from the Clark fluid catalytic cracking unit ("FCCU"). The unit is designed for 50 vol% conversion of the heavy feedstock. Full conversion of the VGO is not required in the hydrocracker since the existing 77,000 bpsd FCCU has enough capacity to convert the remainder of the unconverted VGO from the hydrocracker which will be low sulfur quality. This allows the hydrocracker to have a smaller second stage reactor than is typical for full conversion VGO hydrocrackers, which reduces the capital cost of the hydrocracker. The new sulfur recovery plant is rated at a sulfur capacity of 417 LTD. In addition to the sulfur plant, a new Shell Claus Offgas Treater ("SCOT") tailgas unit is being constructed as well as a sour water stripper and amine regenerator. Recovered sulfur will be purchased by Clark and shipped via rail at a new rail siding. Modifications to the existing Refinery units include upgrading the crude/vacuum unit from the existing 232,000 bpsd of crude oil feed to 250,000 bpsd of crude oil feed. The modifications include changes to process exchangers to provide more preheat to the vacuum tower, upgrading the vacuum tower heater, and miscellaneous pumps and piping. In addition, the GFU 243 distillate hydrotreater has been modified by the replacement of the existing reactor which will extend the cycle length and capability of the unit. These modifications are scheduled to be completed at least six months prior to the mechanical completion of the coker, hydrocracker and SRU (currently estimated at November 1, 2000). In addition to the GFU 243 hydrotreater reactor replacement, the GFU 241 hydrotreater (which is not being leased) reactor will be replaced with a new reactor, and the GFU 242 hydrotreater existing two reactors are being replaced with the reactor from GFU 243. These modifications are to ensure adequate cycle life upon completion of the Upgrade Project. A new naphtha hydrotreater guard bed reactor will be installed on the coker plot site to remove silica and di-olefins from the coker naphtha. Silica is used to control foaming in the coke drums and has a boiling point in the naphtha range. Silica is a permanent poison for reformer catalyst and must be removed prior to processing in the reformer. Di-olefins are unstable compounds which tend to polymerize over time. This polymerization results in the formation of a high boiling point material which will have a negative effect on reformer yields as a result of excessive coking. The existing guard bed reactor located on the 1344 reformer site currently used to remove silica will be converted to hydrotreating service and placed in series with the existing naphtha hydrotreater, thereby increasing the effective reactor volume of the naphtha hydrotreater. Other offsite modifications will be made consisting of inter-connecting piping, addition of a flare, modifications to the fire water system, addition of electrical distribution systems, a new cooling tower, and site improvement. Clark plans to receive a minimum of 125,000 bpsd of crude oil at the Refinery docks. A study was performed by Lanier & Associates, a marine engineering and consulting firm, which concluded that Clark's dock facilities are adequate to support the required capacity. The remainder of the crude oil will be delivered to the Sun terminal at Nederland which is located approximately 15 miles from the Refinery from where the crude oil is sent by Clark's pipeline to Clark's Lucas terminal. The crude oil is shipped from the Lucas terminal to the Refinery via a company-owned pipeline. The Sun terminal, which has five ship docks, three barge docks and approximately ten million barrels of storage capacity, can receive all 250,000 bpsd of crude oil if necessary and the pipeline can transport this quantity to the Refinery. Clark and Chevron/Gulf, the owner of the Refinery B-13 prior to Clark, have had a long term relationship with the Sun terminal and PGI sees no reason that the availability of the Sun terminal would change. Clark utilizes the Sun terminal under a year to year evergreen contract. PGI believes that the crude import facilities are adequate to accommodate the volumes of crude oil contemplated for the Upgrade Project's operation. If, for some unforeseen reason, the Sun terminal would not be available or would have reduced capacity, the Refinery would have other alternatives. A Unocal terminal, also located at Nederland, is connected to an idle Chevron pipeline which could easily be connected to the Lucas terminal. This terminal has 6.2 million barrels of storage and two ship docks. The Refinery also has access to the Louisiana Offshore Oil Port through a Texaco pipeline which could be used to transport approximately 100,000 bpd. UPGRADE PROJECT COSTS A definitive Upgrade Project construction cost estimate including both the EPC Contract and the Clark EPC Contract has been prepared by Foster Wheeler and Clark. PGI's review of this cost consisted of an evaluation of each major cost category, in comparison with similar cost categories for other United States Gulf Coast projects. The total construction cost for the Upgrade Project is $636 million, excluding working capital, financing expenses, capitalized interest, and owner's costs. This includes the PACC EPC Contract of $544 million and $92 million for the Clark EPC Contract. The cost of the major new PACC units and a portion of the offsites are incorporated in the EPC Contract, while the Clark portion of the revamps and offsites will be incorporated in the Clark EPC Contract. An itemization of the construction cost is shown below. TABLE IV-1 UPGRADE PROJECT CONSTRUCTION COST ESTIMATE (Million $) EPC Clark EPC Contract Contract Total -------- --------- ----- New Units (coker, hydrocracker, SRU)............. 442 0 442 Existing unit revamps............................ 0 44 44 Offsites......................................... 27 48 75 Contingency, Escalation, and Profit.............. 55 -- 55 Spare Parts, Other............................... 20 -- 20 --- --- --- 544 92 636 B-14 Other Upgrade Project costs borne by both Clark and PACC include items such as Upgrade Project management team expenses and salaries, insurance, startup costs, training, legal and other miscellaneous costs that are not covered by the EPC Contract. The $52 million allowance for other PACC costs, not including contingency, appears to adequately cover the expected categories. An additional contingency of $28 million has been included with this estimate. The breakdown of the other PACC Project cost estimate is shown below. TABLE IV-2 UPGRADE PROJECT OTHER COST ESTIMATE (Million $) PACC CLARK TOTAL ---- ------- ----- Project Management Team.............................. -- 26(/1/) 26 Startup Costs, Taxes................................. 20 -- 20 Legal and Consulting................................. 11 2 13 Financing Expenses................................... 21 -- 21 Contingency.......................................... 28 -- 28 --- ------- --- 80 28 108 (1) Includes construction management fees of $7 million to be repaid to Clark by PACC over 3 years following startup. The total Upgrade Project cost estimate is $833 million ($636 million in construction cost, $108 million of other Upgrade Project costs and $89 million of capitalized interest expense). Based on its analysis of the construction and other Upgrade Project cost, PGI believes that the budget will be adequate based on comparison to similar construction in the United States Gulf Coast region in recent years and based on the fact that 98% of major equipment has been procured, design is 70% complete and site excavation and foundation work is well advanced. The Upgrade Project contingency and escalation allowance is sufficient, excluding excessive discretionary changes or force majeure events. B-15 UPGRADE PROJECT SCHEDULE Upgrade Project mechanical completion is based on a 31-month schedule from the start date of April 1, 1998, which PGI feels is achievable. [Chart of Figure IV-2 Project Schedule] The key Upgrade Project milestones defined in the EPC Contract are as follows: Milestone Date ------------------- ------------------------ Target Mechanical Completion November 1, 2000 Guaranteed Mechanical January 1, 2001 Completion (start of delay damages) Mechanical Completion Default March 1, 2001 Substantial Reliability Default September 1, 2001 Guaranteed Final Completion December 1, 2001 The 60-day Reliability Test is planned to be carried out as soon as possible after PACC Project startup and stable operation. Achievement of Substantial Reliability in the Reliability Test must occur before September 1, 2001. Guaranteed Final Completion or debt buydown must occur prior to December 1, 2001. The delay damages and performance damages applicable are discussed in EPC Contract section of this report. B-16 TECHNOLOGY ASSESSMENT The selected technology for the processes that form the Upgrade Project are typical of the preferred processes currently used in the industry and are well integrated into the existing Refinery. In all, PGI believes that the Upgrade Project will be able to perform as planned based on the technology selected. Each major unit or category of the Upgrade Project is discussed below. DELAYED COKER The processing design selected by Clark to upgrade heavy sour Maya crude oil consists of a delayed coker and VGO hydrocracker integrated with Clark's existing processing units. This design is widely accepted in the industry as the preferred method of upgrading heavy sour crude oils like Maya. PGI believes that Clark has chosen well proven technology to upgrade Maya crude oil that will result in the planned yields and economics. Delayed coking technology has been utilized for well over 50 years and is one of the most widely used processes to upgrade low value heavy residue into higher value light products. The process is based on the principle of severe thermal cracking which essentially breaks high molecular weight molecules into lower molecular weight molecules via high temperatures. The portion of the residue that does not crack is left as coke which is a coal-like solid material and, in the case of coke derived from Maya crude oil, is typically burned as a fuel. The delayed coking process incorporates specially designed high velocity heaters which minimize coke formation in the heaters. The heater effluent flows into the coke drums where the coking reaction takes place and hydrocarbon vapors are vented to a fractionator. The delayed coking process is considered a semi- batch process because once a coke drum is full it is taken off-line and the heater effluent is switched to another coke drum. The heads of the drum are then opened and the coke is drilled out of the drum using a high pressure water jet. The hydrocarbon vapors leaving the coke drum during normal operation are fractionated yielding a fuel product, a propane/propylene product, a butane/butylene product, a naphtha product which is sent to the catalytic reformer, a light gas oil product which is blended to the diesel pool after hydrotreating, and a heavy gas oil product which is sent to the hydrocracker. The delayed coker being constructed is a modern Foster Wheeler design incorporating a low operating drum pressure and a low recycle rate. A lower operating pressure results in more favorable product yields and a lower recycle rate which reduces unit operating costs. The delayed coking technology will be provided under a license with process guarantees from Foster Wheeler in the EPC Contract. Foster Wheeler is a very experienced licensor of delayed coking technology having designed over 100 coker units, representing an 80% market share, with the largest being 120,000 bpsd. Although the 80,000 bpsd coker is fairly large in size, Foster Wheeler has designed five units with a capacity of 75,000 bpsd or greater. Two of these have been in operation for several years and three others are under construction. The key equipment items of a delayed coker are the coke drums and coke drum size is limited by the ability to cool the coke during the decoking cycle. Recent unit designs, including the PACC coker, have required larger coke drums to achieve design rates. The coke drums being utilized for the PACC coker are similar in size to two recent Foster Wheeler projects and have a proven and successful operating history. VGO HYDROCRACKER Hydrocracking VGO is also a well proven technology of upgrading VGO to lighter, more valuable products. The hydrocracker employs fixed bed catalysts with high pressure hydrogen to crack heavy feedstock into lighter, more valuable products. In addition, the sulfur concentration of the products is reduced to very low levels as compared to the feed. The hydrocracking process design is licensed from Chevron who also provides a process guarantee. Chevron has conducted pilot plant testing on the proposed PACC feedstocks and has verified the projected yields and process conditions. The pilot plant testing provides credibility to the hydrocracker yields assumed in the Base Case and PGI believes that the projected yields can be achieved. SULFUR RECOVERY The new 417 LTD SRU will operate in parallel with existing units and is designed to recover 99.8% or greater of the hydrogen sulfide in the feed gas. Amine acid gas and sour water stripper acid gas are routed to a Claus SRU using technology licensed from Amoco Corporation. The tailgas from the Claus sulfur plant is B-17 processed using the SCOT process, licensed by Shell Oil Company, to produce an acid gas stream that is recycled back to the Claus plant to achieve the desired recovery. The effluent gas from the SCOT Tailgas Cleanup Unit is thermally incinerated in a Tailgas Thermal Oxidation Unit to convert all of the remaining sulfur compounds into sulfur dioxide (S0\\2\\) before dispersion of the gas to the atmosphere. The effluent gas from the SRU and SCOT is expected to comply with the regulatory requirements for sulfur plants operated in Texas refineries. The SRU is being designed by a joint team of Ortloff Engineers, Ltd. (process and technology) and Pro-Quip (engineering and construction) under the supervision and responsibility of Foster Wheeler. Ortloff and Pro-Quip have often worked together over the past ten years to design and construct a variety of sulfur recovery systems. PGI believes that the technology selected for the SRU and the Ortloff/Pro-Quip team will deliver a well-designed unit with adequate sulfur removal capacity to support both the Clark Project and PACC Project operation at full capacity. The Sour Water Stripper and Amine Treating Unit are generic open art units that were designed by Jacobs Engineering Group ("Jacobs") and will be constructed by Matrix Engineering under Foster Wheeler's supervision and responsibility. These units are commonly found in all refineries and do not involve any unique technology. PGI has reviewed the design basis for these units and believes that the units will be adequate for the purpose intended. REFINERY RENOVATIONS AND UPGRADES The majority of renovation and upgrade capital will be spent on upgrading the existing crude unit to process primarily Maya crude oil and to increase capacity by about 10% from 232,000 bpsd to 250,000 bpsd. The revisions involve addition of heat exchangers, re-configuration of piping, replacing pumps, replacing vacuum tower packing, and adding tubes to the vacuum tower heater. These activities are of the type that are typically carried out by refineries during turnarounds. The process design has been carried out by Jacobs and Foster Wheeler under Clark's supervision. The majority of the crude unit work is to be conducted during a turnaround scheduled for March 2000. PGI believes that the crude unit design is adequate to support the processing of the proposed volume of Maya crude oil required to support the PACC and Clark operations and that these revisions will be completed before Project start-up. The GFU-241, GFU-242 and GFU-243 distillate/kerosene hydrotreaters are being upgraded to increase capability for handling the higher sulfur distillate products produced from the more sour crude slate. The modifications involve increasing the size of reactors and catalyst volume through replacement of reactors. These types of small debottlenecking projects are routinely carried out in refineries. A portion of this work (GFU-243) has already been completed. PGI believes that the hydrotreater revamps will be adequate to support the PACC and Clark's operations and that these are estimated to be completed three to six months prior to PACC Project start-up. OFFSITES, AND UTILITIES The major activities to be carried out in this category are . Interconnecting process and utility piping pumping between the new units and the Refinery . Upgrade of crude pumping station . Conversion of Tanks 108 and 109 to coker feed storage . Coke handling outside battery limits of PACC . Addition of piping and pumps to feed new sour water stripper . Provision of a new cooling tower to provide cooling water to both Clark and PACC . Construction of a new dedicated flare for the new units . Construction of a new 13.8 kV substation to supply power to the new units. Additional power to the Refinery will be supplied from the APCI hydrogen plant and Entergy . Install truck and rail loading facilities for sulfur . Construction of a new control building for the new units . Expansion of the firewater loop to the new units B-18 The offsites and utilities items are a collection of typical refinery projects. The majority of the capital is for the interconnecting piping and electrical substation. PGI has reviewed the design basis for these items and believes that the planned offsites and utilities will be adequate for both the Clark Project and PACC Project. PGI further believes that the offsite and utilities items do not pose a major technological or construction delay risk to Clark or PACC. PROJECT CONTRACTS CRUDE OIL SUPPLY AGREEMENT In March 1998, Clark signed the PMI Contract with PMI. The PMI Contract is designed to provide a stable and secure supply of Maya crude oil to PACC for over eight years commencing upon completion of the Upgrade Project. The PMI Contract incorporates the use of a formula that acts as a proxy for calculating the difference between light products and heavy oil or resid prices. The PMI Contract provides stabilization for this differential for up to 210,000 bpsd of Maya crude oil. The Base Case assumes a Contract Quantity of 160,908 bpsd. Pricing--The base price of Maya crude oil is the formula price used by PMI to price the majority of PMI Maya crude oil sales. The formula price of Maya crude oil is stated as follows and is a 5-day average of the formula components: Maya Price = 0.40* (WTS + FO No. 6, 3%S) + 0.10*(LLS + Brent DTD) - DF where WTS = the average Platt's prices for West Texas Sour crude oil, $/B LLS = the average Platt's prices for Light Louisiana Sweet crude oil, $/B Brent DTD = the average Platt's prices for Brent Crude Oil, $/B FO No. 6, 3% S = the average Platt's prices for fuel oil having 3%, sulfur content $/B DF = discount factor subject to adjustment by PMI, $3.50/B at time of signing For WTS, LLS and Brent, the price is the average of the high and low spot prices as quoted by Platt's Crude Oil Marketwire. For FO No. 6 Fuel Oil, the price is the average of the high and low spot prices as quoted by Platt's Oilgram U.S. Marketscan, U.S. Gulf Section, Waterborne Column. The PMI Contract provides for an alternative mechanism for calculating the price of Maya crude oil under certain conditions where there is a lack of adequate buyers of Maya and the formula price is not able to be confirmed in the market. The alternative pricing methodology calculates the price of Maya based on a marker crude oil, gasoline, diesel, and No. 6 fuel oil through the use of a multiple regression formula where the coefficients of the regression formula are based on historical pricing. If the formula price of Maya deviates sufficiently from the predicted price of Maya using the multiple regression technique, then the multiple regression formula will be used to determine the price of Maya. The marker crude oil used in the regression formula can be any actively traded crude with similar properties to Maya (although it does not need to be a heavy sour crude) with transparent pricing, significant USGC market depth, and widely available published pricing. Differential--The Differential is incorporated into the PMI Contract to provide PACC with a stabilized average coker gross margin. This is effected through the application of a discount to the market price of the Maya crude oil when the Differential falls below a negotiated floor of $15 ("Guaranteed Differential") or through the application of a premium when the Differential exceeds $15. The Differential formula is defined as follows: Differential = (0.5*RUL) + (No. 2 Oil) - (1.5*No. 6 Oil) where RUL = average of Platt's prices for conventional, non-RFG 87 octane gasoline, $/B No. 2 Oil = average of Platt's prices for 0.2% sulfur No. 2 fuel oil, $/B No. 6 Oil = average of Platt's prices for 3% sulfur No. 6 fuel oil, $/B Prices are calculated on a monthly average based on the low spot prices in the U.S. Gulf Section, Pipeline column of Platt's Oilgram Price Report for RUL and No. 2 oil and the Waterborne column for No. 6 oil. B-19 On a monthly basis the difference between the Differential and the Guaranteed Differential is calculated. If the Differential is greater than the Guaranteed Differential, then a monthly surplus exists. If the Differential is less than the Guaranteed Differential, a monthly shortfall exists. At the end of a given quarter, the monthly shortfalls and surpluses are netted. If a net shortfall exists, then PACC will receive a discount on crude oil in the succeeding quarter equal to 36.6% (the typical percentage of coker feedstock derived from one barrel of Maya processed through the crude unit) of the net shortfall times the Contract Quantity times the number of days in the quarter (assumed to be 90 days) up to a maximum $30 million in any given quarter. Any excess of this amount will be carried to the next quarter with interest applied. Conversely, if a net surplus exists, then Clark will pay a premium on the crude oil received in the succeeding quarter equal to 36.6% of the net surplus times the Contract Quantity times the number of days in the quarter limited to a maximum of $20 million in any given quarter, subject to PACC having an aggregate shortfall position at the end of the prior quarter. As above, any excess of the $20 million cost will be carried to the next quarter with interest applied. The total premium paid by PACC will not be greater than the aggregate of discounts received in prior quarters plus interest. Interest is applied quarterly at a rate of LIBOR + 1% on the aggregate of discounts received in prior quarters. Duration--The PMI Contract has an eight year Differential period. The Differential period commences upon the earlier of (1) Upgrade Project completion, which is defined in the PMI Contract as having achieved mechanical completion, commissioning and processing at a rate of at least 80% of Refinery and coker design capacities for at least thirty consecutive days and (2) July 1, 2001, which date may be extended for reasons of force majeure. If the Upgrade Project has not reached these completion criteria by January 1, 2001, monthly extensions can be purchased. Either PMI or PACC have the right to terminate the PMI Contract after eight years subject to a minimum one-year phase out period. Force Majeure--The force majeure clause in the PMI Contract includes as part of the definitions "interruption, decline or shortage of Seller's supply of Maya available for export from Mexico (including, without limitation, shortage due to increased domestic demand)". This clause is standard for PMI oil supply agreements and would presumably allow PMI to invoke force majeure if Mexican refinery demand for Maya increased more rapidly than production. In PGI's knowledge, this aspect of the force majeure clause has not been exercised with other buyers of Maya crude oil. Based on its crude oil supply/demand forecast, PGI does not expect this clause to be invoked during the term of the PMI Contract. PGI does expect relatively constant projected domestic demand for Maya, while large increases in Maya production are planned. According to the PMI Contract, any reduction in PACC's Maya supply volume would be in proportion to total reductions in Maya supply to other large quantity Maya customers, or if too few, then to industry. PACC would not be disadvantaged compared to other contract buyers of Maya crude oil. Pricing Forecast and Effect on PMI Contract The PMI Contract was reviewed by PGI utilizing PGI's oil and refined products price forecast. The Differential formula was applied with pricing discounts and premiums applied as appropriate. Figure IV-3 illustrates the PGI forecast of the calculated Differential formula compared to the Guaranteed Differential. The Differential formula is designed to be managed quarterly; however, PGI's forecast is made on an annual basis only and therefore the Differential formula was applied annually as well. As can be seen in the figure, a net shortfall situation exists in 2001 and 2002, the first two full years of operation, where PACC receives a discount. After 2002 and onward, the Differential formula moves to a net surplus position. A premium is applied in 2003 through 2006 equal to the aggregate discount received by PACC in 2001 and 2002 plus interest at a rate of LIBOR + 1%. From 2007 forward, PACC is forecast to pay the market price for Maya crude oil since the remainder of the Differential formula period results in a net surplus position. B-20 [Chart of Figure IV-3 PMI Contract Guaranteed Differential] These results are not surprising and confirm that the basic intent of the PMI Contract is only to minimize adverse cycle risk to secure adequate cash flow for debt service obligations. It is not structured as a permanent subsidy for oil purchases. Figure IV-3 confirms that the parties to the PMI Contract have chosen an appropriate level for the margin protection which should not put unfair pressure on PMI over an extended period of time. APCI HYDROGEN CONTRACT APCI and PACC will enter into a twenty-year take and pay, if delivered contract under which PACC will purchase up to 80 million standard cubic feet per day ("MMSCFD") of hydrogen from APCI, of which 55 MMSCFD will be on a dedicated take and pay basis. APCI will build a new steam methane reformer and two PSA purification units on Refinery property leased from Clark. APCI will also produce steam and electricity for sale to Clark. Commencement date of the contract is required to fall between October 6, 2000 and December 6, 2000 (the "Start-up Date"). PGI believes that the Start-up Date is achievable. If the hydrogen supply plant fails to be ready to operate due to APCI acts or omissions on or before December 6, 2000 or prior to December 6 if the PACC Project requires hydrogen due to completion of the PACC Project, APCI will pay liquidated damages of $19,250 per day for each day of delay up to $1,155,000. If PACC is unable to take the hydrogen on or before December 6, 2000 then PACC will pay liquidated damages of $38,500 per day for each day of delay up to $1,155,000. APCI will guarantee that the hydrogen supply will achieve an on-stream factor of at least 98% and will pay liquidated damages up to $1,800,000 if the on-stream factor falls below 98%. If APCI achieves an average on-stream factor greater than 98%, the APCI will be eligible for a bonus of up to $900,000. Penalties or bonus payments due to on-stream reliability will be determined after two complete years of operation. The hydrogen price is set from an initial base natural gas price and then adjusted monthly for natural gas price, a labor cost index and the producer price index. The pricing mechanism is market based and is typical for U.S. Gulf Coast hydrogen contracts. The price is consistent with the hydrogen price utilized in the Base Case. PGI believes that the Hydrogen Contract provides hydrogen and utilities at a competitive price and adequate volume to PACC. REVIEW OF INTERCOMPANY AGREEMENTS There are four Intercompany Agreements between Clark and PACC. These are: . Coker Complex Ground Lease And Blanket Easement Agreement--Land lease for site of PACC units and access to common facilities by PACC. B-21 . Ancillary Equipment Site Lease And Easement Agreement- Lease of Clark owned units. . Product Purchase Agreement--Clark purchase of products produced by PACC . Services and Supply Agreement--Supply of all required services and utilities by Clark to PACC and fees paid by Clark to PACC for processing Clark crude oil through all PACC owned and leased units The intent of the Intercompany Agreements is to transact access, supplies, services and product purchases to reflect arms-length market mechanisms and fair market pricing terms. Coker Complex Ground Lease and Blanket Easement Agreement ("Ground Lease") The Ground Lease provides for the leasing to PACC of land and any improvements located on such property encompassing the sites for the coker, hydrocracker and SRU. Clark also grants easements to PACC for access across the Refinery including ingress, egress, piping, wiring and other purposes as necessary. An additional easement is provided for use of the Refinery dock for unloading crude oil and feedstocks and for loading of products. Under the Ground Lease, Clark also grants PACC a license to use various other facilities at the Refinery required for operation of PACC. The payment for the Ground Lease is structured as an up-front payment of $25,000 for the initial 30 year term of the lease. Any lease extensions will be based on a fair market rental value as agreed between Clark and PACC or by a value determined according to the defined appraisal procedure contained in the Ground Lease definitions. The Ground Lease can be extended past the initial 30 year term in 5 year increments. At the end of the Ground Lease, any improvements may be dismantled and removed by PACC or, if not removed, shall become the property of Clark. Ancillary Equipment Site Lease and Easement Agreement ("Ancillary Equipment Lease") The Ancillary Equipment Lease is an agreement between Clark and PACC covering PACC's lease of the site where the Ancillary Equipment is located, access to the Clark owned process units. In PGI's opinion, this agreement is critical for PACC to operate in a stand-alone, as well as, the normal mode of operation. The process units and offsites included in the Ancillary Equipment Lease are: . Crude/vacuum unit, AVU-146 .Hydrotreaters, GFU-242, GFU-243, CRU-1344 The Ancillary Equipment Lease also grants easements to the PACC for required access to the leased facilities. Clark is upgrading the crude and vacuum units to increase processing capacity from 232,000 up to 250,000 bpsd. Clark is obligated to substantially complete, at its sole cost, upgrades on or before October 1, 2000. After start-up of the PACC-owned units, PACC will pay to Clark quarterly lease payments of approximately $8 million adjusted for inflation through the lease term. An operating fee determined in accordance with the fixed and variable costs for Clark processing PACC's crude oil through the Ancillary Equipment is due monthly. The quarterly lease fee is based on a capital recovery charge for both existing asset values and the cost of the upgrade. PGI has reviewed the cost of the lease and operating fees and believe they reflect arm's length basis pricing and fair market terms. The initial term of the Ancillary Equipment Lease is for a 30 year period. The agreement allows for five 5-year extensions. The rent for any extension period will be based on a fair market rental value as agreed between Clark and PACC or by a value determined according to the defined appraisal procedure contained in the agreement definitions. B-22 Product Purchase Agreement The Product Purchase Agreement ("PPA") provides for the sale to Clark of all the finished and unfinished products produced by PACC. The agreement is a take and pay, if delivered contract and as such obligates Clark to accept and take delivery of all the products that are produced by PACC and delivered to Clark. In the event that Clark cannot take delivery, PACC has the right to sell the products to a third party. Products are sold based on market based pricing using industry market indices such as Platt's and Oil Price Information Service ("OPIS"). Intermediate or unfinished products are discounted for quality considerations and both finished and intermediate products have appropriate charges for marketing and terminaling costs when these products are sold to third parties. PGI reviewed the pricing methodology applied in determining the product values and considers it to be industry typical and to reflect arm's length basis pricing and fair market terms. PGI also verified that the product pricing contained in the PPA is consistent with the pricing used in the Base Case projections. All products have required target specifications, delivery points, quantity, measurement, and quality references. The contract term is for a 30 year period and therefore extends well beyond the term of the financing. The agreement addresses the required product mix to be produced and states that any changes made must maximize the overall Refinery profitability and cannot maximize Clark's profits at the expense of PACC. The PPA is structured to work in conjunction with the Services and Supply Agreement. If any dispute arises regarding the PPA, PACC and Clark are required to meet and resolve the conflict. In the event an agreement is not reached either party may initiate an arbitration proceeding. Services and Supply Agreement The Services and Supply Agreement ("SSA") incorporates all the services and supplies that Clark provides to PACC including the following: (i) management and supervision of the PACC construction; (ii) supervision, management and maintenance of the required Ancillary Equipment (crude/vacuum and hydrotreaters) needed by PACC to generate on a continuous basis the required product mix as defined in the PPA; and (iii) provision of services, supplies and certain feedstocks to PACC. The SSA has a 30 year term and gives PACC the right to terminate the agreement for an event of default that is not remedied by Clark. The agreement provides for Clark arranging for PACC the delivery of Maya and light sour crude oils and other Refinery feedstocks including hydrogen, provides dock, pipeline, and storage services, enables Clark and PACC to arrange for processing of their crude oils and products in the respective PACC and Clark facilities, supplies operations, management, technical, and maintenance personnel, supplies all required utilities, chemicals and catalysts,and fuel, and arranges for all the support services needed to operate PACC in regulatory compliance as well as safely and reliably. The SSA also contains provisions addressing the processing rights by Clark for the use of its required capacity in either PACC-owned units or the Ancillary Equipment. The agreement also grants PACC approval rights with respect to annual budgets and operating plans submitted by Clark. These provisions protect PACC's ability to generate revenues and its profitability. Each of the services mentioned above are tied to specific schedules that describe the specific service to be provided and address quantity, measurement, applicable pricing, and billing. Both PACC and Clark are obliged to make the required payments that cover the reimbursable costs incurred by the party providing the service and/or supply. PGI reviewed the pricing methodology applied in determining the specific services and/or supply to be provided and consider it to reflect arms-length basis pricing and fair market terms. PGI also verified that the revenues and expenses as a result of these services and supplies are reflected in and consistent with the Base Case. The SSA is structured to work in conjunction with the PPA. If any dispute arises regarding the SSA, PACC and Clark are required to meet and resolve the conflict. In the event an agreement is not reached either party may initiate an arbitration proceeding. B-23 ENGINEERING, PROCUREMENT, AND CONSTRUCTION CONTRACTS There are two separate contracts with Foster Wheeler: (i) the Clark EPC Contract between Clark and Foster Wheeler; and (ii) the EPC Contract between PACC and Foster Wheeler. Following is a summary discussing each one. Clark EPC Contract The renovation and upgrade of the crude unit, vacuum tower and other Ancillary Equipment required to be performed by Clark pursuant to the Ancillary Equipment Lease represents primarily routine turnaround work and will be done by Foster Wheeler under the Clark EPC Contract. Under this contract, Foster Wheeler is paid on a "cost-plus" reimbursable basis rather than a fixed-cost basis. The cost estimate for this work is $92 million. PGI expects completion of this work to occur no later than October 2000. This contract contains retainage, warranty and process guarantee provisions from Foster Wheeler that are customary for reimbursable-cost basis refinery upgrade contracts. This contract will be assigned to PACC as security for Clark's construction obligation under the Ancillary Equipment Lease. EPC Contract The EPC Contract is a lump sum fixed price basis contract for the engineering, design, procurement, construction, installation, testing and documentation of a new 80,000 bpsd delayed coking unit, a 35,000 bpsd hydrocracker, a 417 LTD sulfur recovery unit and various offsites for a fixed price contract amount of $544 million. The EPC Contract in most aspects follows a typical industry standard format that is routinely used for a lump sum fixed price basis agreement. In addition it incorporates substantial terms and conditions pertaining to completion and acceptance (covering performance and reliability) that is more demanding of Foster Wheeler. The engineering, procurement, and construction of the PACC process units (delayed coker, hydrocracker, amine and sour water stripper, and sulfur plant) are on a fixed price basis. The EPC Contract specifically defines the scope, deliverables, responsibilities, obligations, price, and schedule. PGI believes that the EPC Contract will provide the PACC with a well designed facility and a reliable operation. The EPC Contract contains the mechanism required to control the cost and completion dates, and is structured to reduce the risks associated with overruns, schedule delays and integration with the process units outside of PACC that are needed for the continuous operation. It also incorporates the auditing requirements which will be carried out by the IE who will independently monitor construction and certify completion and performance. Following are some specific comments pertaining to some of the more critical contract terms and conditions. Contractor Responsibilities In general terms, the EPC Contract protects PACC's rights, and obligates Foster Wheeler to meet all its obligations and responsibilities in the engineering, procurement, construction, commissioning, and startup of the Upgrade Project. Clark management has provided specifications ("Turnkey Specifications") which Foster Wheeler is contractually obligated to meet in the performance of their responsibilities. The EPC Contract language is very specific and careful in making Foster Wheeler, and solely Foster Wheeler, responsible for all obligations under the EPC Contract including completing construction within a fixed price and project schedule, including all work performed by subcontractors. Foster Wheeler non-performance is penalized by rebates and setoffs. These in turn are related to delay and performance liquidated damages caused by delays in mechanical completion or under performance when PACC cannot achieve process design guarantees and reliability criteria defined in a Performance Test. Delay damages amounting up to $70 million and performance damages amounting up to $75 million are specified in the contract. The Performance Test includes both a Capacity Test and a Reliability Test. Performance Test liquidated damages are applicable if and when PACC is not able to operate at design capacity or produce the B-24 specified salable products, or achieve the guaranteed plant efficiency. In addition, the Reliability Test requires Foster Wheeler to demonstrate that PACC can achieve minimum daily net margin targets. In the event the daily net margins are not achieved, Foster Wheeler is obligated to make Reliability Test buydown payments. While the EPC Contract does contain a clause allowing the payment of a bonus in the event of early completion, it is only paid upon final acceptance of the Upgrade Project. The contract also subjects Foster Wheeler to a penalty equal to the full amount of the contract, i.e. $544 million in the event of default. Scheduled payments will be based on achieving determined engineering, materials procurement, and construction progress. PGI will be required to review the Upgrade Project's progress in relation to expenditures. In addition to delay and performance liquidated damages, the contract requires a 10% letter of credit that serves as a retainage in which PACC is the beneficiary and has, as owner, the right to withhold funds in the event of Foster Wheeler not completing all items as required in the Turnkey Specifications. Project Cost and Schedule The EPC Contract has terms that address fixed price and firm completion dates. The terms and conditions typically found in EPC fixed price contracts or LSTK arrangements that allow either cost or schedule increases, are included in the EPC Contract. Specifically, changes in laws or regulations, force majeure situations, and change orders are part of the EPC Contract and are drafted in detail. Sufficient site work has been completed at the Refinery to eliminate unknown underground structures risk, which is sometimes an additional cause for change orders, and make this the responsibility of Foster Wheeler. PGI believes that the cost estimate as well as the construction schedule are both very realistic and achievable, that the risk allocation is fair and should not result in cost increases or disputes. Changes in Laws or Regulations In PGI's opinion, changes in laws or regulations should be of little impact since Clark has obtained revised permits needed for PACC construction. Further details on the construction permits are contained in the Environmental Section of this report. Force Majeure and Owner Delays The force majeure clause is considered typical of those found in EPC contracts, and should not be a cause for construction project overruns or schedule delays. The intent of the EPC Contract is that Foster Wheeler be a qualified contractor (as addressed in the Contractor's Expertise clause) who is experienced in doing similar projects and is familiar with the location where construction is to take place. Language in the force majeure section restricts extraordinary weather related delays by specifying a 30 year history and limits labor problems to industry wide and/or nationwide incidents. PGI believes that Foster Wheeler has taken into account its experience in refinery projects and knowledge of the Port Arthur region, and built in sufficient time for uncontrollable events that may occur during the course of the construction which may have an impact on construction cost and schedule. The EPC Contract also addresses owner caused delays which can be the basis for contractor claims. Clark management and Foster Wheeler have organized an experienced team, which in our opinion is critical to having a successful Upgrade Project. Clark management is committing sufficient personnel as needed to undertake the Upgrade Project management and support Foster Wheeler efforts. Based on our meetings with Clark management and Foster Wheeler, we believe that sufficient capable and experienced human resources and planning are (and will be made) available, as needed, to achieve successful completion of the Upgrade Project. Change Orders Change orders can be a major cause for cost overruns and schedule delays. Change orders can be avoided if specifications are very clear and do not have any undefined scope or responsibilities. As currently drafted, B-25 PACC has the right to approve or disapprove change orders at its option. In PGI's opinion, the EPC Contract includes satisfactory terms to provide a comprehensive and complete technical specification to the contractor and to provide sufficient supervision and controls to minimize the potential for change orders. PGI must approve any individual change order in excess of $500,000 and change orders, in the aggregate, in excess of $5 million. Based on the advanced design (over 70% complete as of June 1999), 98% completed procurement, civil construction being almost finalized and the remaining construction time of 16 months, the risk of excessive and expensive change orders is considered minimal. Warranties The objective of the EPC Contract is to deliver a facility that performs according to design. A facility that is completed on time and within budget but does not perform according to design would be of little value. Sufficient safeguards in the form of warranties and performance guarantees are needed beyond mechanical completion, commissioning, and startup to assure a safe, reliable, and profitable operation. The EPC Contract contains language on mechanical warranties and performance guarantees that cover all defects and deficiencies caused by errors and omissions in engineering and design or otherwise. The warranties vary from one to three years and cover civil and mechanical events. The mechanical warranties vary from one to two years depending on mechanical completion dates and are considered typical for EPC contracts. The guarantees cover plant capacity, efficiency, reliability, and the integration of the PACC Project with the rest of the Refinery. In PGI's opinion, these warranties and guarantees are adequate. Performance Tests and Completion Guarantee The EPC Contract addresses both delay penalties and performance penalties. Delay penalties cover delays in mechanical completion while performance penalties cover performance at below design conditions. Delay damages are triggered if Foster Wheeler does not achieve mechanical completion or Guaranteed Reliability by the Guaranteed Mechanical Completion Date (as defined in the EPC Contract) by January 1, 2001 and if certain other milestones are not met after the PACC Project is mechanically complete. The cap of $70 million for delay damages is sufficient to cover non-capitalized debt service payments through December 31, 2001. The EPC Contract incorporates performance tests that confirm PACC's capability to process the required amount of feedstocks, produce the design product yields and specifications, and consume the energy (fuel and electricity), and utilities, as specified in the operating assumptions of the Base Case economic model. Foster Wheeler guarantees completion and has to pass a sixty-day extended period test that will reflect the various unit capacities to achieve operation at process design conditions. Each unit must operate smoothly in a safe and efficient mode and in environmental compliance for extended periods that demonstrate its reliability over the long term. Tables IV-3 through IV-7, Performance Test Standards, show how the performance is validated. If the Performance Test fails to achieve the Guaranteed Reliability (as defined in the EPC Contract), Foster Wheeler is subject to loan buydown payments, for up to $75 million. This buydown amount is considered by PGI to be adequate to cover the majority of foreseeable risks. In addition, Foster Wheeler is exposed to 100% of the EPC Contract amount until PACC achieves Substantial Reliability which is defined as 95% of the Guaranteed Reliability as defined in the EPC Contract. PGI believes that the definition, configuration and duration of the agreed performance and reliability test are suitable to demonstrate that PACC will be able to achieve the operating rates and efficiencies assumed in the Base Case and that these tests and other rights that PACC has under the EPC Contract represent an appropriate completion risk mitigation. B-26 Independent Engineer The EPC Contract includes provisions which address the role of an IE. The IE participates in reviewing the procedures and practices followed in the engineering, procurement, and construction phases of the Upgrade Project. Although the IE does not perform or participate in any process simulations, equipment specifications, mechanical drawings, piping and instrument diagrams, civil and structural design, fabrication, and construction activities, the IE provides an opinion on whether the engineering and construction is following standard industry practices, required implementation policies exist, an experienced and qualified management team is in place, sufficient checks and balances exist, and that any specific requirements are in place. The IE is also responsible for certifying that the required steps are being taken by the management team to assure that the Upgrade Project is being designed and built in accordance with the required standards and within the allotted budget and schedule. In the event that any problems are detected, the IE is responsible for bringing these to the attention of the Financing Parties as well as PACC management. Construction Monitoring While it is PACC's responsibility to review and certify that each EPC Contract invoice is valid and is due, the IE will monitor the construction progress (by reviewing periodic progress reports and making routine visits to the construction site) and will certify to the disbursement agent that construction funds can be released. The IE will check that the necessary procedures are in place to assure that PACC will not approve any payments without carrying out the necessary approval process. The EPC Contract provides the IE with the right to spot check any payments and ascertain whether the payments being made correlate with the construction progress being reported (and observed based on field inspection). The IE will also certify PACC's acceptance of mechanical completion after carrying out the required due diligence review. TABLE IV-3 PERFORMANCE TEST STANDARDS Purpose: The Performance Test measures the ability of PACC facilities to generate cash flow, adequate to service its Senior Debt outstanding, using the assumptions for average market prices of products and feedstocks, and average unit prices for utilities contained in the Base Case for years 2001 through 2011. The Performance Test is intended to demonstrate that the PACC facilities can operate in conjunction with the Clark facilities at the forecasted throughput, yield and operating efficiency without any effects of changes in the market prices of, or price relationships between, feedstocks and refined products. GENERAL TEST PARAMETERS 1. The Performance Test will consist of a Capacity Test and a Reliability Test to be conducted following Mechanical Completion and Commissioning. All General Test Parameters will apply to both the Capacity Test and Reliability Test. 2. The candidate crude oils charged to crude unit AVU-146 will be from the list in Table IV-4 and actual crude oils as agreed to between PACC, Foster Wheeler USA Corporation, and the Independent Engineer during all test runs. The volume mix of crudes shall be approximately 80% from the heavy category and 20% from the light sour category. 3. All products produced and sold to Clark during the Performance Test shall meet the specifications set forth in the Process Technical Specifications set forth in Schedule 1.7 in the Turnkey Specifications. To the extent the products actually produced deviate from the product specification, the price shall be B-27 adjusted to reflect the values for the processing or sale of such products by PACC or Clark R&M as approved by the IE. 4. During the Performance Test, the Guaranteed Emission and Effluent Limits shown in Table IV-5 shall not be exceeded on a ratable basis. 5. During the test period, only one component of spared equipment will be utilized at any time where redundant components (pumps, compressors, etc.) are installed. This does not preclude switching among components of spared equipment during the test period. 6. For purposes of measuring the consumption of each feedstock and utility, and production of products for calculation of Daily Net Margin, Clark and PACC will use the measurement systems and equipment that are utilized for accounting purposes. Meters shall be installed for measurement of the main feeds, products and utilities between Clark and PACC. Calibration of such meters will be carried out prior to the commencement of the Performance Test. 7. Details of the yield accounting approach including measurement tolerances, analytical procedures, scheduling and reporting during the Performance Test will be developed between PACC and Foster Wheeler personnel and the IE before the commencement of the test. 8. PACC and Foster Wheeler may from time to time request modifications to any of the procedures of the Performance Test. Such modifications will become effective upon the consent of the IE, which consent shall not be unreasonably withheld or delayed. CAPACITY TEST 9. During a continuous 72-hour period, which can be during the Reliability Test or at another time, the PACC units will be operated at or within the conditions identified in the process unit performance guarantees included as attachments to Schedule 5.3 of the EPC Contract. The capacity test will demonstrate that PACC can achieve design capacity and efficiency. The summary table below shows some of the major capacity test parameters. CAPACITY TEST PARAMETERS DELAYED COKER Charge Rate 80,000 B/D minimum Total Liquid Product (C5+) yield 58.9 wt% minimum Coke Drum Cycle 18 Hours maximum HYDROCRACKER Charge Rate 35,000 B/D minimum Total Liquid Product (C5+) yield 111.2 LV% minimum Hydrogen Makeup 2,152 SCF/BBL Feed maximum (Chemical) SULFUR RECOVERY UNIT Recovered Sulfur 417 LT/Day minimum Sulfur Recovery Efficiency 99.80% minimum Incinerator Effluent 250 ppm vol SO2(/1/) maximum -------- (1) Dry and 0% excess air basis 9.1 Crude unit AVU-146 will be operated by Clark at a nominal 250,000 bpsd during the Capacity Test to provide adequate vacuum bottoms feedstock for the delayed coking unit (DCU 843). 9.2 The delayed coker feedstock will be vacuum resid. The hydrocracker feedstock will be mixed coker gas oil, light cycle oil, and vacuum gas oil. B-28 RELIABILITY TEST 10. Crude Unit AVU-146 will be operated for 60 consecutive days at a crude oil charge rate of not less than an average of 245,000 B/D to provide feedstocks for the Project units. The coker will be operated during the same period at an average charge rate of not less than 76,340 B/D of vacuum resid feedstocks. There will be no limitation on the amount of feedstock processed in Crude Unit AVU-146 and vacuum resid feedstock sent to the coker subject to physical limitations of the Crude Unit AVU-146 and safety considerations. The hydrocracker will be operated during the same period at an average charge rate of not less than 33,250 B/D of mixed coker gas oil, light cycle oil and VGO feedstocks. 11. The Guaranteed Reliability of the Project will be determined by the achievement of 100% of the Daily Net Margin of $904,500 as described below. The Project can achieve Substantial Completion by achieving at least a Daily Net Margin of $859,200 and by Foster Wheeler paying Reliability Test Buydown Payments according to the schedule in Table IV-6. The "Daily Net Margin" generated during a Performance Test is calculated as follows: (i) the sum of Product Values (as defined below) for each product produced during the Performance Test minus the sum of the Feedstock Values (as defined below) minus Variable Costs (as defined below) divided by (ii) the number of days in such Performance Test. The Daily Net Margin calculation shown in Table IV-3 in Schedule 5.3 of the EPC Contract is based on an 80/20 Maya/Arab Light crude slate; any alternate Light Sour crude oil will affect product yields and utility consumption. It is not anticipated that changes in the Light Sour crude selection will have a material impact on the Daily Net Margin. However, any change in crude selection and the corresponding Daily Net Margin calculation will be subject to review and agreement by PACC, Foster Wheeler, and the IE. As used in Daily Net Margin, the following terms have the following meanings: "Product Value" means, for any product produced in a Performance Test, (i) the volume or other measure of such product produced during such Performance Test multiplied by (ii) the Dollar Value (as defined below) of such product. "Feedstock Value" means, for any feedstock consumed in a Performance Test, (i) the volume or other measure of such feedstock consumed during such Performance Test multiplied by (ii) the Dollar Value of such feedstock. "Dollar Value" of any product or feedstock means the value therefore as set forth in the Base Case and as listed in Table IV-7 or, if there is no value set forth in Table IV-7 for such product or feedstock, as the case may be, a value determined by PACC, with the written approval of the IE, on a basis consistent with the methodology used to determine the prices of similar products or feedstocks, as the case may be, set forth in the Base Case, adjusted to reflect any differences in quality and transportation costs. "Variable Costs" means the total of utilities consumed (or produced) multiplied by the unit price of each utility as specified by the Services and Supply Agreement assuming base fuel and electricity costs of $2.307/MMBTU and $.032/KWH, respectively. The consumption basis for each utility is outlined in the Heavy Oil Project Guarantee Basis in Schedule 5.3 of the EPC Contract.

Jefferson County is classified by the EPA as an ozone non-attainment area. The county was a serious ozone non-attainment area and was reclassified to a moderate ozone non- attainment area on June 3, 1996. The past relationship (under both Gulf and Chevron ownership) as well as the current relationship between Clark and the federal and state environmental regulators, is satisfactory. As evidenced by correspondence between Clark and the agency, good lines of communication are open between Clark and the regulators and this relationship has facilitated frank and cooperative discussion on items pertaining to permits and compliance. The EPA carried out a multimedia (air, water, solid/hazardous waste) inspection in April 1997 which indicated that Clark was essentially in compliance. Only two deficiencies were identified; Clark has since corrected these items to EPA's satisfaction. The most recent TNRCC inspection conducted in 1998 reported the refinery to be essentially in compliance. FLEXIBLE AIR PERMIT ALTERATION AND SEPARATION Clark holds five conventional TNRCC permits and one umbrella or bubble type flexible air permit. Clark is currently covering most of the Refinery operations under the flexible air emissions permit (Permit Nos. 6825A and PSD- TX-49). This air permit is in lieu of the traditional single source permits and incorporates all of the existing air emissions sources under one umbrella permit. The flexible air permit establishes 10 individual maximum allowable emission rates (VOC, NOx, SO2, CO, PM, H2S, HF, NH3, Benzene, and MTBE) and defined individual limitations (which includes control of fugitive emissions, opacity, operation of SRUs, visible emissions from heaters and boilers, and continuous emission monitoring systems, amongst others). The flexible permit requires Clark to make certain investments beginning in 1994 and ending in 2004, that will ultimately reduce the total air emissions by installing best available control technology ("BACT") on all grandfathered equipment. In return, Clark was granted a permit that does not specify emission limits on each source but instead provides an overall plant limit for each of the ten pollutants mentioned above. The starting time was determined by Chevron's/Clark's promise to pursue a flexible permit in 1994. The permit was approved in 1996. PGI reviewed Clark's 1998 emissions summary which reported all individual emission caps to be below the maximum allowable limits. Clark is required to make this demonstration to the TNRCC every quarter, until continuous emission monitoring equipment is installed that will allow this demonstration on a real time basis. In view of the reported emissions documentation and conversations with Clark and the TNRCC, it is apparent that emissions are routinely within permissible limits. Clark's 10 year flexible permit capital investment requirements (1994-2004) includes the addition of low NOx burners, a vapor recovery system at the docks, fugitive emissions control and monitoring, continuous emissions monitoring equipment, and process revisions needed to lower the SOx emissions in the FCCU flue gas. FCCU emissions reductions will be accomplished by lowering the sulfur content in the FCCU feedstock to 0.3wt%. Clark is targeting to have all items completed by 2002. The estimated total investment plan is approximately $33 million to achieve all the items. PGI reviewed documentation provided by Clark that evidences the permits under the TNRCC jurisdiction that changed ownership in April 1995 after Clark acquired the Refinery from Chevron USA, Inc. and Chevron Pipe Line Co. In December 1996, the existing permits were captured under a single permit referred to as the original Flexible Permit. The Flexible Permit was amended on August 31, 1998 to allow Clark to undertake the Project. On March 9, 1999 a request was made by Clark to the Office of Air Quality of the TNRCC for permit alteration and separation of Flexible Permit 6825 A. On March 18, 1999, an additional request was made to TNRCC to B-32 once again alter the Flexible Permit and in addition amend Permit 2303 A. These requests will have the net result of separating PACC from the Flexible Permit and incorporate the emissions from PACC to Permit 2303 A. This existing permit covers emissions from four crude oil storage tanks (of which two will be used as coker feed storage tanks) which are located in the general vicinity of the PACC site. Permit 2303A will have emissions capped by individual source rather than the flexible concept. The TNRCC notified Clark on April 29, 1999 that the amendment to Permit 2303A and the alteration to Permit 6825A had been approved. Subsequently, on May 12, 1999 Clark requested TNRCC to change the ownership of Permit 2303 A from Clark to PACC. On May 28, 1999 the TNRCC approved the change of ownership. This permit gives PACC the right to construct and operate the Coker Complex. Both permits remain under TNRCC account ID No. JE-0042-B. The TNRCC considers this reasonable since Port Arthur is functionally one emissions site. The revised original Flexible Permit approved by TNRCC requires that construction of the Upgrade Project begin no later than February 2000. This condition has already been satisfied since construction has already begun. The revised Flexible Permit would require a permit modification to continue to operate the existing coker units once the new coker becomes operational. In addition to the existing permits, on July 9, 1999, the TNRCC issued to PACC standby permits (Permit Nos. 6825Z and PSD-TX-49Z) that would replace the existing Clark Flexible Permit and become effective upon notice by PACC to the TNRCC. These permits are subject to the same special conditions contained in the existing Clark permits and would allow PACC to operate the Clark Ancillary Equipment required to support the Coker Complex operation. WASTEWATER AND, SOLID AND HAZARDOUS WASTES The current operation treats all Refinery process wastewater prior to its discharge into the Neches river via the Refinery joint outfall canal. Chevron, prior to selling the Refinery to Clark, installed a new wastewater treatment plant that treats all Refinery wastewater and the wastewater produced at the Chevron petrochemical plants. The treatment plant is considered a state of the art facility and incorporates various stages of treatment prior to the wastewater being discharged. Current wastewater discharge parameters are routinely below the TNRCC and EPA limits. Clark provided documentation which shows the Refinery to be in compliance at percentage rates better than the industry average. Solid and hazardous wastes are handled, stored, and transported according to the required RCRA regulations and do evidence any material non-compliance issues. PGI reviewed a RCRA compliance inspection report done in conjunction with the multimedia inspection which shows Clark to be essentially in compliance. EXISTING SITE CONTAMINATION The Refinery site was determined to be contaminated prior to Clark's purchase from Chevron. Black & Veatch, an engineering and environmental consultant, was retained (November 1994) by Clark to ascertain the pre-existing contamination of the entire refinery complex. As a condition of the fuels refinery sale by Chevron to Clark, Chevron retained the environmental liability for the pre- existing site contamination with exception to those areas classified as excluded areas which include the areas immediately under and within 100 feet of the prime fuels operating units (crude unit, FCC, reformer, alky, etc.) The ground areas that will be leased by PACC have potential soil and underground water contamination; however, this contamination remains a Clark liability. The area in which the existing Clark fuels refinery is located represents approximately 3% of the total Refinery facilities area. The areas occupied by the tank farm and Chevron's petrochemical plants are also potentially contaminated and remain under Chevron's responsibility. Environmental impact studies performed by Clark's environmental consultants, Black & Veatch, reportedly indicate minimum risk to the surrounding surface and underground water bodies that are considered as potable drinking water sources. The underlying geology at the site shows Beaumont clay at an average depth of 30 feet which has a low permeability and tends to impede the downward flow of groundwater. In PGI's experience it is common for remediation not to be immediately mandated in circumstances where no potable B-33 water sources are endangered. A previous report (November 1994) by Black & Veatch also indicates that ground water remediation will not be performed for individual areas of the Refinery, but for the Refinery as a whole. For those areas outside of Clark's boundaries, Chevron agreed with the environmental authorities on a site remediation plan, and today, site remediation in areas under Chevron's responsibility is in progress. The intent is that the remediation work will continue until the site has reached the negotiated conditions. The area that will contain the major PACC units, namely the coker and the hydrocracker, has potential soil and underground water contamination. Chevron has agreed to pay Clark an agreed settlement amount, based on forecast cleanup costs (of any remediation of soil located above the groundwater table), of approximately $1.4 million in order for Clark to assume this potential liability. Black & Veatch calculated a cleanup cost estimate of $1 million for capital costs and $0.8 million for operating costs (based on insitu stabilization of the soil). Black & Veatch indicated that the settlement amount would be sufficient for the level of remediation (if remediation were mandated). As Clark retains all environmental liabilities under the Coker Complex Ground Lease and Ancillary Equipment Lease for existing site contamination, PACC is protected against any environmental exposure with respect to existing conditions. EFFECT OF PROPOSED GASOLINE SULFUR SPECIFICATIONS Future gasoline specifications beyond the Complex model have been issued by the EPA and are referred to as Tier 2. There is currently a debate between the automobile manufacturers and the refining industry concerning proposed levels of sulfur in gasoline. The automobile manufacturers association argue that further improvements to the catalytic converter requires a lower sulfur gasoline fuel as sulfur is a temporary catalyst poison. The proposed specifications are an annual average sulfur concentration of 30 parts per million ("ppm") with a per gallon maximum of 80 ppm. To achieve these specifications, refiners will be required to make capital expenditures to construct additional processing units to treat gasoline type streams. New specifications will likely be decided in 1999 with new requirements going into effect in 2004. As the low sulfur specifications are currently in the proposal stage and no new regulations have been passed at this time, most refiners including Clark do not have definitive plans to construct the additional equipment necessary to meet the proposed specifications. With the new PACC hydrocracker and the existing VGO Hydrotreater (GFU244), Clark will likely only require additional hydrotreating on the FCCU gasoline and light straight run streams. Clark and PGI expect this capital expenditure to be no more than $50 million through the use of idle equipment currently located at the Refinery. Based on Clark's past commitment to meet the regulations at the Refinery, it is reasonable to expect that Clark will spend the capital necessary to meet the new proposed specifications. MTBE Recent concerns regarding groundwater contamination by MTBE in California have prompted a panel of the Environmental Protection Agency to recommend that Congress enact a ban on MTBE usage. In addition, the governor of California has signed an executive order regarding the phasing out of MTBE usage over the next few years. In the past the refinery has produced reformulated gasoline (RFG) using MTBE produced through a tolling agreement with Huntsman Chemical. Although the refinery will continue to have the capability to produce RFG containing MTBE, PACC does not plan to produce MTBE. If a ban on MTBE usage were to spread throughout the U.S., including Clark's market area, the Refinery would be prohibited from utilizing MTBE in its gasoline blends. Such an occurrence would generally affect all refiners more or less equally. PGI believes that a ban on MTBE usage would not have a material effect on PACC's operations and cash flow or the competitiveness of the Refinery. B-34 COMPETITIVENESS OF REFINERY Purvin & Gertz utilizes a proprietary methodology to predict the relative net margin of a refinery of a given configuration compared to other refineries with different configurations. The index, termed processing power index or PPI, is based on the conversion capability of the refinery, the hydrogen uptake per barrel of crude oil processed, and relative size. The PPI is based on seven different standard index USGC refineries with varying degrees of complexity and types of crude oil processed. The refinery configurations include both cracking and coking modes of operations processing sweet and sour crude slates in various combinations. Calculation of the PPI assumes that the refinery operator is prudent in all matters regarding operating costs, maintenance practices, safety and environmental compliance. Based on our analysis, the Refinery will move into the top five refineries on the US Gulf Coast based on PPI. In comparison, the Refinery ranks number seventeen per the PPI in the pre- expansion mode. The graph below illustrates where the refinery is today and post-project. [Chart of Figure IV-4 Relative Margin Indicator for 29 USGC Refineries] B-35 V. ECONOMIC MODEL GENERAL Clark management developed and provided to PGI an economic model to simulate economics for PACC. PGI examined the model and confirmed the assumptions and calculations by performing an independent review. PGI considers the economic model to be an accurate representation of the projected revenues, expenses, and net cash flows generated by PACC. The objective of the economic model is to analyze the expected revenue, net income, and DSCR's. PGI verified the feedstocks consumption, products yields, operating costs, processing fees, utility/environmental fees, marketing fees, maintenance turnaround charges, and capital (initial and sustaining) expenditures based on documents provided by Clark. Our evaluation did not include verification of financing assumptions, depreciation, reserve fund requirements, or taxes (corporate, sales, state, municipal, etc.) that were assumed by Clark and are incorporated into the economic model. Depreciation is calculated on a 30 year straight line method for book basis and 10 year double declining balance method for tax purposes. Cash income taxes are assumed to be at a rate of 35%. The economic model calculates, on a semi-annual basis, the expected PACC revenues, project expenses and DSCR beginning November 1, 2000 and ending in 2015. For the purposes of this report the results from the economic model are reported on a yearly basis. The model incorporates the PGI price forecast adjusted from a basis of 2% inflation reduced to 1%. A 1% inflation basis increases conservatism in estimating the debt service coverage ratios. The basis for the PGI price forecast is discussed in detail in the separate "Crude Oil and Refined Product Market Forecast". PACC consists of the delayed coker, hydrocracker, sulfur plant and certain offsites. PACC is integrated with the existing operations at the Refinery and its economics are based on the sale of intermediate and finished product streams at market rates to Clark. In addition to finished and intermediate product sales, PACC incurs lease and operating fees related to the leasing and operating costs incurred by the upgrading of PACC intermediate products in PACC owned and leased units and receives processing fees from Clark for the processing of Clark intermediate products in the PACC owned and leased units. Finished product and intermediates pricing are based on widely accepted market publications such as Platt's with quality discounts or premiums applied where applicable. All pricing is established at the Refinery gate by applying appropriate transportation costs and fees to the US Gulf Coast basis. CAPITALIZATION OF PACC PACC's capital costs, operating cash deficiencies during construction and financing expenses (including interest during construction) are to be funded through a $135 million equity contribution and the issuance of bank term debt ($325 million) and capital markets debt ($255 million). The bank term debt has a final maturity of 7.5 and 8 years with a prepayment mechanism allowing for 75% of the excess cash flow to prepay outstanding bank term debt. The remaining 25% of free cash flow is available to fund the debt service reserve account and thereafter for dividends subject to certain restrictions. The capital markets debt will consist of $255 million with a term of 9.3 years and an average life of approximately 7.0 years. Semi-annual interest payments are capitalized through the construction period to March 1, 2001 with cash interest payments beginning in July 2001 and scheduled principal amortization beginning in January 2002. A $75 million working capital facility will be established to provide letters of credit for non-Maya crude oil purchases and to provide "compensating collateral" under the PMI Contract. A $150 million Guaranty Insurance Policy will be issued by Winterthur International Insurance Company Limited, an "AA-" rated insurance company, in lieu of a traditional working capital facility for letters of credit for all PACC Maya crude oil purchases. Premiums are paid annually in advance beginning at financial close. B-36 In lieu of an initial debt service reserve account being funded by PACC (equal to six months of interest and principal amortization payments), a Debt Service Reserve Insurance Guarantee ("DSRIG") is to be provided by Winterthur. Premiums on the DSRIG will be paid annually in advance beginning at financial close. The DSRIG is reduced over time and replaced with a debt service reserve account that will be funded initially with the residual excess cash flow generated by PACC after prepayment of bank debt. New PACC equity of $135 million (19% of total sources of funds) is to be contributed by Blackstone Capital Partners III L.P. (90%) and Occidental Petroleum (10%). A PMI surplus reserve account ("PMI Account") will be established to retain funds in an amount equal to the net quarterly surpluses that will have accrued pursuant to the Differential formula up to a maximum amount of $75 million, which will be automatically reduced to $50 million upon repayment in full of all bank term debt. This reserve will be adequate to provide liquidity to PACC in case of reduced cash flows because of a delay in discounting Maya until all prior surpluses have been fully used. The combination of a fully-funded PMI Account and the debt service reserve account will provide PACC with liquidity up to 1.25 years of debt service. At financial close, PACC, with PGI's certification, will reimburse Clark for all PACC related capital outlays incurred since Upgrade Project inception (a projected total of approximately $139 million though July 31, 1999). PACC will also pay Clark $2.2 million for transfer of value items including the PMI Contract and other items. REVENUES PACC generates revenues from processing approximately 200,000 bpsd of crude oil (80% Maya and 20% light sour), selling products to Clark (mainly LPG, diesel, intermediates, coke, and sulfur) and receiving fees from Clark for processing Clark feedstocks (approximately 50,000 bpsd of crude oil). The salable products are based on the material balance yields used as the basis in the economic model which incorporates yields guaranteed by Foster Wheeler as part of the Performance Test. The prices received for the products sold are based on the PGI market price forecast. As indicated in prior sections of this report, the prices are adjusted from market prices for quality and freight for price realization at the refinery gate. Since feedstocks and products purchased and sold by PACC are handled by Clark, a per barrel fee component is charged to PACC. The rates used in the financial model and listed in the table below are representative of typical handling fees charged by third-party entities. TABLE V-1 HANDLING FEES Finished Product.................. $0.021/bbl LPG's & Intermediates*............ $0.042/bbl Crude............................. $0.030/bbl Coke.............................. $0.010/bbl -------- * Fee will only be charged if intermediate is sold to a 3rd party Sales to a 3rd party will occur during a turnaround or during abnormal operation B-37 FEEDSTOCKS TO PACC Feedstocks purchased by PACC consist of Maya crude oil purchased under the PMI Contract from PMI and a light sour crude oil purchased on the spot market. To allow processing of the Maya crude oil at the Refinery, a volume of light sour crude oil (the model assumes Arab Light) equal to approximately 20% by volume of the total crude oil processed is required. The crude oil will be fed to the crude/vacuum unit that is being leased by PACC and PACC will pay a lease fee to Clark for utilizing 100% of the crude unit. In addition to crude oil purchased by PACC, Clark has the right to process additional crude oil purchased by them through crude/vacuum units. In such case, a processing fee will be paid by Clark to PACC for such processing. Products from the crude/vacuum unit will be split according to the respective percentages of PACC and Clark crude oil processed (approximately 80% PACC and 20% Clark). In addition to the crude oil liquid feedstocks, PACC will purchase hydrogen needed for the hydrocracker from APCI at a price of 1.8648 times fuel value plus a fixed fee. Residue from the vacuum unit will be fed to the new delayed coker. As mentioned, the proportion of residue fed to the coker is equal to the percentage of PACC crude processed through the crude/vacuum units. Light products from the delayed coker will be sold back to Clark at market reference prices. Coker heavy gas oil will be fed to the hydrocracker along with light cycle oil from Clark and VGO from the crude/vacuum unit. Products from the hydrocracker are sold to Clark at market reference prices. The sulfur plant will process acid gas only from PACC units and have the capability to process minor amounts of acid gas from the Clark units, if necessary. YIELDS FROM PACC Product yields and quality estimates from PACC have been made by Clark and Foster Wheeler. The yields are based on information provided by each of the process licensors. Coker yields are based on Foster Wheeler's extensive experience with designing and constructing delayed cokers worldwide. The hydrocracker yields are based on pilot plant testing performed by Chevron on feedstock similar to that used in PACC. The assumed product yields and qualities are reasonable and consistent with expectations for such refinery units. The Base Case projections are those yields which have been guaranteed by Foster Wheeler as part of the performance test in the EPC contract. These yields represent 97% of design yields for the coker and 95% of design yields for the hydrocracker. Beginning on December 15, 2000, revenues for PACC are initiated with a 80% onstream operation assumed for a 45 day period. Following the 45 day start-up period, the remainder of 2001 is assumed to operate at 95% of normal operating rates. Normal operation is assumed to begin in 2002. OPERATING COSTS AND SUSTAINING CAPITAL Clark has prepared detailed estimates of the variable and fixed operating costs for the PACC units (coker, hydrocracker, sulfur plant). These estimates are the basis of the Services and Supply Agreement. Variable costs are those items that vary with throughput which include fuel, electricity, steam, other utilities, and chemicals consumed in daily operations. PACC's variable cost estimate has been developed from detailed utilities estimates prepared by Foster Wheeler and associated sub-contractors. The current estimate for variable costs, which are predominantly expenditures for fuel and electricity, is approximately $0.38/BBL or about $28 million per year. Variable costs are priced as follows: . Fuel (total consumed)--Calculated based on the fuel gas price forecast. . Steam (included in the fuel expense line item)--Based on the incremental cost of steam from APCI with prices indexed to the fuel gas price forecast. . Electricity--Based on the incremental cost of electricity from APCI and other third party providers with price indexed to the fuel gas price forecast. . Other--Includes water, nitrogen, and other miscellaneous services. B-38 Fixed costs are expenditures that are unaffected by varying throughput and include items like administration, process labor, maintenance, taxes, insurance, and overheads. Clark also includes catalyst and chemicals in fixed costs to coincide with their accounting conventions. Catalyst and chemicals are assumed to be purchased as needed and are amortized over the useful life. Initial supplies of catalyst and chemicals are included as start up costs. Labor expenses include both operations and maintenance and are estimated to be $10 million per year. In 2001, expenses include an additional $1.5 million for new unit troubleshooting. Expenses are inflated at 2% per year.

In year 2001, an additional expense of $2.5 million is assumed for troubleshooting. Total repairs and maintenance as an average percentage of unit replacement cost over 15 years including maintenance labor, materials, contract labor, turnaround and mandatory capital are 4.5% for the PACC units and off- sites. Major turnarounds of the coker, hydrocracker, and crude unit are assumed to occur in years 2004, 2008 and every four years thereafter. Crude unit heater de-coke and hydrocracker catalyst change are assumed to occur during interim outages in years 2002, 2006, and 2010. B-39 Environmental costs are based on historical Refinery environmental costs of $0.2 million per year associated with operating the existing cokers plus $0.6 million per year for waste services, inflated at 2% per year. An incremental insurance premium of $2 million per year for business interruption and process units is included based on Marsh & McLennan estimates. The base tax rate included is 3% of the assessed property value less assigned abatement and environmental exemptions for pollution control equipment. General and administrative (G&A) expenses are estimated at $700,000 per year. This includes $200,000 for accounting and optimization activities to be conducted by Clark, and $500,000 for corporate activities such as tax services, information services, legal fees, insurance administration, bondholder relations and SEC filing requirements. These expenses are adjusted for inflation at 2% annually.

The sustaining capital outlays are projected to be lower than average in the early years when the equipment is new and higher than average in the later years. The operating and maintenance cost and sustaining capital projections set forth in the economic projections are reasonable and sufficient for the operation and maintenance of PACC.

In addition, under the Ancillary Equipment Lease, PACC pays operating fees to Clark for all units, which include fees for turnaround and sustaining capital accrual, fuel and fixed operating cost. Other costs include utilities and environmental services which include items such as nitrogen, demineralized water and other services. These other costs are in line with market rates and are relatively minor in proportion to other expenses. These fees encompass both a fixed and variable cost component as well as a capital recovery component. The capital recovery component in the lease fee assumes a 25% after tax rate of return for the coker and hydrocracker, 15% after tax rate of return for other new capital investment, and 3% after tax rate of return for use of existing assets. Under the Services and Supply Agreement, processing fees are paid to PACC by Clark to process Clark's portion of the vacuum residue in the delayed coker. In addition, Clark pays PACC a processing fee to process LCO, coker HGO, and crude still VGO through the hydrocracker. Clark also pays for use of a portion of the crude/vacuum unit and hydrotreaters. B-41 The table below summarizes the processing, operating and lease fees for the Upgrade Project.

AMORTIZATION Turnaround expenses for the various units are amortized over the life of the turnaround. The expenses are based on industry averages for units of similar size. Turnaround expenses for the crude unit and hydrotreater are paid by Clark and included as part of the operating fees incurred by PACC. Cash turnaround costs will be accumulated annually through a restricted cash account specifically for turnaround expenditures. The turnaround amortization period for all major PACC units is 4 years. Financing fees are amortized based on the final maturity of the various issues and amortization of royalty payments are based on the depreciable life of the asset. CONSTRUCTION MANAGEMENT SERVICES Construction management services will be provided by Clark prior to Final Completion under the SSA at a fixed cost of $7 million. These costs will be paid by PACC over a 3 year period following startup of the PACC Project (approximately $2.7 million per year including interest). B-42 DEBT SERVICE COVERAGE RATIOS DSCRs are calculated by taking after tax cash flows (defined as EBITDA less sustaining capital expenditures less amortized turnaround expenses less cash taxes) as a ratio to scheduled principal amortization and cash interest payments. In addition to the Base Case, a variety of other cases were examined to test the robustness of PACC economics and the availability of cash flow to service the outstanding debt. These cases and results are described in the table below: TABLE V-6 DESCRIPTION AND RESULTS OF CASES Average Minimum Case Description DSCR DSCR -------------------------------- ---------------------------- ------- ------- Base Case.......................

Increased fixed and variable cost by 20% - -------- * In 2007, the Backcast Case cash flow available for debt service shortfall amounts to approximately $3.0 million. The shortfall is primarily a result of prior year surpluses which have not been fully used so that discounts are not allowed under the PMI Contract. This scenario is mitigated by the PMI Account. Consequently, in this year, PACC will have a fully funded PMI Account of $50 million, debt service reserve account of $37 million and over $100 million of additional cash available for debt service. In the Backcast Cast without PMI Contract, cash flow available for debt service shortfall amounts to approximately $5.0 million, with a debt service reserve account of $37 million and over $100 million of additional cash available for debt service. B-43 The results demonstrate that PACC is able to service its debt obligations under a variety of scenarios. Detailed tables supporting these cases are shown in Tables V-9 to V-26. Each case is discussed in more detail below. BASE CASE The Base Case has been defined in preceding paragraphs. PGI believes that the Base Case projections are achievable and that they are a reasonable representation of the expected performance of PACC. The Base Case provides a minimum after tax DSCR of 2.0 and an average after tax DSCR of 2.4. SENSITIVITIES Due to the uncertainties necessarily inherent in relying on assumptions and projections, it should be anticipated that certain circumstances and events may differ from those assumed and described herein and that such circumstances may affect the results of our Base Case. In order to demonstrate the impact of certain events on the Base Case economics, a number of sensitivity cases were tested. It should be noted that other cases than those described below might be considered. The sensitivities recommended are not presented in any particular order with regard to the likelihood of any case actually occurring. In addition, no assurance can be given that all relevant sensitivities are addressed, that the level of each sensitivity is the appropriate level for testing, or that only one (rather than a combination of more than one) of such variations or sensitivities could impact PACC in the future. Base Case--No PMI Contract This sensitivity involves the loss of the PMI Contract. In the Base Case, PACC receives a discount on Maya purchases during the first two years of operation followed by a surplus situation whereby PACC pays a premium on Maya purchases until the aggregate of the shortfalls is offset. Without the PMI Contract in effect, the average DSCR is 2.4 compared to the Base Case of 2.4, with the minimum DSCR being 1.9. The results reflect the fact that the basic intent of the PMI Contract is not to provide a subsidy for oil purchases. Backcast Case A Backcast Case was generated using 1989-1998 historic pricing to correspond to the volume projections for 2001 to 2010. The intent of the Backcast Case is to illustrate historic cyclicality of the petroleum market. On-stream utilization and yields were kept the same as the Base Case. The PMI Contract is assumed to be in place for the Backcast Case. The average DSCR is determined to be 2.0 with a minimum DSCR of almost 1.0 in 2007 (a 1995 pricing environment). In 2007, the cash flow shortfall amounts to only $3.0 million and is a result of the absence of discounts due to prior year surpluses under the PMI Contract. As discussed, to mitigate this risk, the PMI Account is fully funded ($50 million) to cover this shortfall in addition to the $37 million balance in the debt service reserve account. Backcast Case--No PMI Contract An additional Backcast Case was generated which assumes the PMI Contract is not in place. This case results in an average DSCR of 2.0 with a minimum DSCR of almost 1.0. Again, the results do not materially change from the Backcast Case with the PMI Contract for the same reasons explained above. The shortfall of available cash flow for debt service in 2007 amounts to $5.0 million. This shortfall would be covered by the debt service reserve account. Downside Case A downside case was also developed that incorporates 1996 prices during the period 2000-2003 with PGI's forecast used thereafter. This scenario tests the impact of an extended period of weak coker economics. B-44 In the past ten years of history, it was found that the worst year for coker performance in conjunction with the coker gross margin stabilization under the PMI Contract occurred in 1996; hence, the use of 1996 pricing during the first three full years of operation followed by the Base Case assumptions. PGI believes that a three year period of depressed coker economics is highly unlikely and would likely self-correct as a result of a decline in addition of new coker projects. The average after-tax DSCR was determined to be 1.9 with a minimum DSCR of 1.1. During the first three years the DSCR were 1.5, 1.1 and 1.2. Reduced Utilization Case The effect of a change in utilization or on-stream factor was tested by reducing the overall on-stream factor to 95% of the Base Case which effectively is 90% of design rates in bpsd. A reduction in utilization could occur as a result of under-design of key pieces of equipment or mechanical reliability issues. This change in utilization impacts PACC's operating cash flow by only $14.1 million in 2003 (or about 6%) with a reduction in average DSCR from 2.4 to 2.2. Reduced Coker Yield and Reduced Hydrocracker Conversion Cases There is the possibility of achieving less than the expected product yields from the delayed coker and the hydrocracker units. Although PACC utilizes well- proven technology, there is always risk associated with the start-up of newly constructed units. A key performance indicator of delayed coker operation is the percentage of feedstock that is converted to lighter more valuable liquid products. Along the same line, a key performance indicator of hydrocrackers is the conversion of VGO feedstock. Conversion not only impacts the amount of light, more valuable fuels products that are produced, but also adversely affects the VGO balance resulting in the sale of excess VGO. Cases were evaluated to analyze a reduction of 5% of the delayed coker liquid volume yield and a 10% reduction in hydrocracker conversion resulting in average DSCRs of 2.3 and 2.4, respectively. Operating Cost Increase Case Variable and fixed operating costs were both increased by 20% to simulate lower efficiencies and higher than expected labor or maintenance costs. A 20% increase in operating costs results in an average and minimum DSCR of 2.2 and 1.9. An additional sensitivity was performed which assumes that PACC operates without the rest of the Clark facility in operation. This case is discussed in the next section. STAND-ALONE CASE To demonstrate the robustness of the economics of the PACC, PGI developed an alternative case scenario under which PACC continues its operations while the rest of the Refinery not leased or used by PACC in the Base Case discontinues its operations. PACC would continue to have access to all leased and owned units. It is assumed a third-party would replace Clark as operator. In a stand- alone operation, PACC will need to arrange for crude purchases and logistics as well as product sales and logistics. These functions are assumed to be contracted to third parties for fees similar in magnitude to those assumed in the Base Case. CONFIGURATION The stand-alone operation scenario assumes that the PMI Contract remains in effect and that the crude unit continues to process 250,000 bpsd of crude oil. The delayed coker, hydrocracker, sulfur plant, the crude/vacuum unit and the sat gas plant, as well as the distillate hydrotreaters (GFU 242 and GFU 243), will be required to process crude oil. In addition, boilers, tankage, transfer piping, control houses, laboratory, and miscellaneous equipment and buildings are all assumed to be available to PACC. The crude and distillate hydrotreating units are assumed to be available to PACC for the lease fees stated in the Processing/Lease Fees section previously described. B-45 Relatively minor modifications to piping would be needed to implement the stand-alone case. In addition, modifications will be required at the PACC sulfur plant to handle the additional sulfur load which entails the use of oxygen enrichment. Additional variable costs are included in the cash flow model to account for this oxygen usage. PGI believes that the cost to modify the Refinery and PACC to support a stand-alone operation would not exceed $5 million, nor take longer than 3 months to implement. PRODUCTS In the stand-alone operation, the catalytic reformer, FCCU, and the alkylation unit will not be operated. As a result, the only specification products produced will be low sulfur diesel fuel and kerosene. All other product streams from the operating units are intermediate products, specifically light naphtha or penhex, reformer feed, and low and high sulfur VGO and which are sold to the spot market. PRICING Stand-alone product pricing is adjusted to reflect discounts or premiums due to quality, transportation fees, and market discounts. The quality and transportation discounts are applied throughout the pricing period, however, market discounts are applied only for the first 3 years. Naphtha pricing depends primarily on whether the naphtha is light or heavy, whether it has been stabilized, and its naphthene and aromatic ("N+A") content. Heavy naphtha and higher N+A naphtha command a higher price versus light naphtha and low N+A product. Premiums and discounts have been applied as appropriate to naphtha produced in the crude, hydrocracker, and coker units. Light naphtha, for example, is valued to the olefins cracker market and/or gasoline blending and is priced at USGC natural gasoline less the required discount. The effect of introducing 40,000 bpsd of poor quality unstabilized Hydrocracker and Coker naphtha into the reformer naphtha market will result in discounts in addition to the quality discount as supply will outweigh demand. In 1998, the imports of reformer naphtha into the U.S. Gulf Coast were about 60,000 bpsd which represents the incremental supply to meet the demand for reformer feed. Introducing the incremental supply of naphtha into the market will impact the price of naphtha for several years until an equilibrium supply/demand balance is achieved. To account for the market impact of the introduction of additional reformer type naphtha on the market, a 5 c/gallon discount was applied for the first three years of stand-alone operation. Furthermore, typical transportation charges have been applied. Price discounts for the various naphthas produced are shown in Table V-7. Low sulfur VGO was priced using PGI's long term forecast, with no additional discounts, applied as shown in Table V-7. A 2 c/gallon discount was applied to the PGI forecast of HS VGO to compensate for the poor quality and an additional 3 c/gallon was applied to cover the market impact of introducing 50,000 bpsd into the market. The market discount was assumed only for the first three years of stand-alone operation and is based on historical trends related to quality and volume discounts. As with naphtha, all the VGO pricing is adjusted for a transportation fee. B-46 In addition to naphtha and VGO, coke and sulfur pricing have been adjusted for quality and transportation as shown in Table V-7. TABLE V-7 STAND-ALONE CASE--PRODUCT PRICING Crude Stabilized Naphtha USGC Natural Gasoline - 2 c/gal processing fee - 1.5 c/gal transportation Hydrocracker Stabilized Naphtha USGC Natural Gasoline - 2 c/gal processing fee - 1.5 c/gal transportation Hydro.

Coke (FOEB) USGC Fuel Grade Coke - quality adjustment - transportation Sulfur ($/ton) USGC Market - transportation OPERATING COSTS Fixed and variable operating costs were held consistent with the Base Case. These costs, which are market-based and replicate what a third-party could provide, include all fuel and power, labor, maintenance, turnaround, environmental, and associated costs required to operate PACC. All lease and operating fees paid by PACC were also held consistent with the Base Case. All processing fees formerly received from Clark were assumed to be zero. DSCR Both a forecast and backcast case were developed for the stand-alone case. These cases use the same pricing basis as discussed previously in the Base Case and Backcast Case but with the adjustment for the naphtha and vacuum gas oil prices. The CSA is assumed to be in effect. Interest expense and principal amortization were held consistent with the Base Case financial model. The DSCR for these cases are as follows: TABLE V-8 STAND-ALONE CASE DSCR --------------- Average Minimum ------- ------- Forecast.................... 1.9 1.1 Backcast.................... 1.7 0.7 In the forecast case, the minimum DSCR of 1.1 occurs in 2004 which includes a turnaround. Even though the backcast has a minimum DSCR of 0.7 in one year, the PMI Account was fully funded at $50 million and would be able to cover the shortfall of $17.4 million. In the backcast case, the 0.7 coverage coincided with a period of poor coker margins in 1995 and a net aggregate surplus under the PMI Contract, thereby not allowing for Maya discounts. This demonstrates the benefit of establishing the PMI Account. The supporting tables for the stand-alone case are shown in Tables V-27 and V-28. PGI is of the opinion that the stand-alone scenario will be an extremely remote possibility since the Refinery will be one of the most competitive refineries in the USGC after startup of the Upgrade Project. Even in a bankruptcy proceeding against Clark, it would be more beneficial to continue to operate the Refinery, since Clark would continue to receive the lease and operating fees.

INTRODUCTION Purvin & Gertz, Inc. has been retained as Market Consultant to provide a long term crude oil and refined product forecast to be utilized in evaluating the Clark Refining and Marketing, Inc. ("Clark") heavy oil upgrade project ("Upgrade Project") to be constructed at Clark's Port Arthur, Texas refinery. The new process units (coker, hydrocracker, sulfur recovery) and certain offsites are to be constructed by Port Arthur Coker Company L.P. ("PACC") while other modifications to existing units and certain offsites construction will be carried out by Clark. The Upgrade Project is designed to process primarily Mexican Maya crude oil. This study provides an outlook for crude oil and refined products supply, demand and pricing. In addition, a discussion of heavy crude oil availability is provided, along with an analysis of the risk of diversion of Maya crude away from the Upgrade Project.

SUMMARY AND CONCLUSIONS The overall level of crude oil prices is set by the cost of production and supply/demand pressures. If the price is too high, the supply will increase because of the economic attractiveness of developing new reserves or producing existing reserves at higher rates. At the same time, demand is decreased by use of alternative fuels such as coal, natural gas, or nuclear energy, and/or by conservation efforts. The resulting imbalance of supply versus demand forces prices back down. In the same manner, if the price is too low, demand is stimulated, alternative energy supply development is constrained, and adding new reserves becomes less economical. Ultimately, the low prices cause demand to approach capacity limits on production, and the resulting competition for supply drives prices back up. Since the crude oil price crash in 1986, the price of crude has fluctuated around $20.00 per barrel. (Figure II-1). Prices increased in 1990/91 due to the Gulf War, slowly declined through 1994, increased again in 1995/96 as strong demand in Asia outstripped crude production increases. One of the key factors was delays in bringing on new crude production in the North Sea. [GRAPHIC OF FIGURE 11-1-WTI CUSHING CRUDE OIL PRICE] The price of crude oil was beginning to slip in 1997 (Figure II-1) even before the full impact of the Asian Financial Crisis was felt as a result of growth in non-OPEC supplies and over production by OPEC with the return of Iraq. Crude prices continued to weaken throughout 1998 and averaged $11.28 per barrel in December. Prices are increasing in 1999 on the strength of the agreement by OPEC and a few non-OPEC producers to reduce crude production. The price of WTI averaged about $18.00 per barrel in June. C-2 We estimate that OPEC production would have to be constrained to around 80% of capacity (Figure II-2) to bring the market back into balance. The propensity for OPEC members to overproduce is high, so downward pressure will be there until demand grows requiring OPEC to produce at 85 to 90% of capacity. As shown, it will be around 2005 before OPEC production will be back up to 90% of capacity. [GRAPHIC OF FIGURE 11-2-OPEC CRUDE PRODUCTION] The absolute level of crude prices has a very direct impact on the feasibility of the upstream business but crude price differentials have a larger impact on the economics of refinery conversion projects. The heavy/light differential in this report is expressed as the differential between WTI at Cushing and Maya fob Mexico. LIGHT/HEAVY DIFFERENTIAL . The light/heavy differential is the result of a complex balance of a number of factors, such as: -- Absolute and relative demand for light and heavy products. -- Supply of heavy crude oil. -- Conversion capacity supply/demand balance. . In the time period of August 1987 to December 1998, the WTI/Maya differential averaged $5.70/bbl based on Platt's Oilgram Price Report weekly quotes. . For the time period from January 1988 to March 1999, the six-month period moving average of the light/heavy differential ranged from a high of $8.90 to a low of $3.76, with an average of $5.83. . Low oil prices and reduced supplies of heavy oil relative to conversion capacity have caused the differential to narrow in late 1998/early 1999. Despite these adverse conditions, the light/heavy differential averaged about $5.00 per barrel over the past six months. . Purvin & Gertz expects the light/heavy differential to widen from 2000 to 2005, and then remain relatively stable for the remainder of the forecast period. The differential will widen due to a number of factors, such as: --A rise in the price of crude oil. All other things being equal, when the price of crude oil rises the light/heavy differential will tend to widen. --Resurgence of strong product demand in Asia, filling conversion capacity. --Increase in the rate of development of heavy oil reserves in Mexico, Venezuela, and Canada will rapidly increase overall heavy feedstock availability and overwhelm conversion capacity. C-3 . Purvin & Gertz forecasts the light/heavy differential over the 2000 to 2020 time period to average $6.51 per barrel in real terms and $8.18 per barrel in nominal terms (Figure II-1). While there can be considerable volatility in the light/heavy differential, the market fundamentals suggest a widening light/heavy differential which will be beneficial to the Upgrade Project. [GRAPHIC OF FIGURE 11-3-WTI CUSHING minus MAYA FOB MEXICO] HEAVY CRUDE OIL AVAILABILITY . Purvin & Gertz expects adequate supplies of heavy crude oil to be available to the Upgrade Project throughout the forecast period, given that heavy crude production is concentrated in the Western Hemisphere and that we expect production to increase substantially over the life of the Upgrade Project. . The Upgrade Project has been designed to process Maya produced by PEMEX. Purvin & Gertz expects Maya to be abundant given PEMEX's reserves, production levels and plans to expand production. . If the Maya crude is diverted from the Upgrade Project, there are alternative supplies. Although most of the other heavy crude supplies are generally heavier than Maya (22API), they are still heavy crudes that could be used effectively in the new coker. --Contracts for Venezuela heavy crude could probably be obtained since Venezuela plans to significantly increase their supply of heavy crude after 2000. --Contracts for Neutral Zone crude (18API) could probably be obtained since the producers (Saudi Arabia and Kuwait) are having difficulty placing its growing supplies. . The risk of diversion of the Maya crude contracted to be used in the Upgrade Project, is minimal for the following reasons: --A program to significantly expand production of Maya is currently underway and the extra supply will be difficult to place in the market due to the limited capacity of complex refineries required to process it. --The netback for heavy crude shipments to Europe or Asia is low related to U.S. Gulf Coast deliveries. --Heavy crude is run in complex high conversion refineries and the highest concentration of this type of refinery is found in the U.S. Gulf Coast. --The demand for heavy crude outside the U.S. is small and relates primarily to asphalt manufacture; Purvin & Gertz does not expect this to change during the forecast period. --About 75% of the refinery capacity in PADDs I-III is designed for light sweet and light sour crude. The light sweet refineries can not run heavy, high sulfur crude like Maya due to metallurgy and product specifications. The light sour refineries already run as heavy a slate as is practical. C-4 --A heavy crude producer with an equity position in a refinery will choose to run its own crude rather than purchasing from others such as Mexico. PDVSA has equity ownership of over 900,000 B/D of refining capacity in the U.S. (about 30% of the total heavy oil refinery capacity in PADDs I-III) and is following an aggressive strategy to secure markets for its heavy crude in competition with Mexico. --Although Mexico could decide to participate in heavy oil export cutbacks, the cutbacks are not likely to be large and would be prorated over all of its customers. Recently, announced cutbacks have been in the 100,000 to 125,000 B/D range or about 10% of exports. The Upgrade Project would not be materially affected by cuts of this magnitude. PRODUCT DEMAND . Product demand growth varies from year to year but generally averages less than 2% annually. Gasoline growth is the key to overall product growth since the product accounts for 40 to 50% of the total. Jet fuel is the fastest growing product but total demand is relatively small U.S. PETROLEUM PRODUCT DEMAND (Million Barrels per Day) Annual % Change 1998- 1995 1996 1997 1998 1999 2000 2005 2010 2015 2015 ----- ----- ----- ----- ----- ----- ----- ----- ----- -------- Motor Gasoline.......... 7.79 7.89 8.02 8.20 8.39 8.51 8.89 9.42 9.68 0.98 Kerosene/Jet Fuel....... 1.55 1.64 1.66 1.65 1.70 1.74 1.94 2.13 2.31 1.99 Distillate.............. 3.21 3.37 3.44 3.44 3.55 3.65 4.03 4.43 4.83 2.02 Residual Fuel Oil....... 0.85 0.85 0.80 0.82 0.81 0.81 0.78 0.76 0.75 -0.49 Other Products.......... 4.33 4.56 4.71 4.57 4.58 4.63 5.01 5.27 5.49 1.09 Total Demand........... 17.72 18.30 18.62 18.68 19.03 19.35 20.64 22.01 23.06 1.25 Growth, % 0.03 3.27 1.72 0.31 1.89 1.65 1.30 1.29 0.94 REFINERY MARGINS . Purvin & Gertz expects refinery margins for heavy sour crude processors to be significantly higher than for light sweet crude refineries. The Upgrade Project will move Clark's Port Arthur refinery into the top tier of Gulf Coast refineries (Figure II-4).

OECD figures now formally include Mexico, Republic of Korea, the Czech Republic and Poland. World petroleum demand growth in 1996, helped by a cold winter, averaged about 3% or 2 million B/D. Demand grew 2.3% in 1997, gaining 1.6 million B/D. With a mild winter, OECD growth in 1997 was just above 1.4%, whereas, in 1998, growth dropped to nearly zero due primarily to the financial turmoil in Asia. Purvin & Gertz expects U.S. demand to grow at about 1.5% through 2005, but to taper off to about 1% through the remainder of the forecast period. Purvin & Gertz expects Western Europe growth to be slightly less robust than the U.S. but will still average above 1% throughout the forecast period. Without the important influence of Asian growth, world demand growth was nil in 1998. We expect OECD petroleum demand growth to be moderate through the forecast period, rising about 1.3% through 2005 and slowing to the 1% range. This projection assumes rising prices, slowing population growth and softening economic growth through 2000. C-6 NON OECD PETROLEUM DEMAND On the other hand, non-OECD petroleum demand growth (ex FSU) approached 5% per year over the 1990 to 1997 period. Petroleum demand in the FSU collapsed during the early 1990s, pulling down the total non-OECD trend (Figure III-1). However, demand now appears to be stabilizing in that area although weakness due to the current financial problems will continue in the near term. This has resulted in total world growth rates rising in recent years. As a result of the Asian financial crisis, Asian demand declined in 1998 whereas Asian growth from 1990 to 1997 contributed 5.8 million B/D to the total world growth of 7.9 million B/D or 73% of the world increase. Asia's growth averaged 5.1% per year.

C-7 RECENT TRENDS IN THE WORLD PETROLEUM SUPPLY/DEMAND BALANCE OPEC crude oil production bottomed in 1985 at only 16 million B/D as demand growth remained flat and non-OPEC supplies continued to grow with high crude oil prices. This trend intensified competitive pressures to the breaking point and world petroleum prices collapsed in early 1986. The collapse resulted in a reversal of both demand and non-OPEC supply trends. The lower prices enhanced demand internationally and non-OPEC crude oil production, especially in the U.S., decreased as a result of the change. Thus, demand for OPEC crude benefited from both sides of the balance. By 1990, OPEC output had increased to 23.2 million B/D, a 48% increase relative to the low point in 1985. The growth over that period benefited significantly from the shock effect of the price change and it was enhanced by strong economic growth in most regions of the world. In 1998/99, demand for OPEC crude declined significantly as a result of Asia financial crisis and continued growth in non-OPEC crude. In response to decreased world demand for OPEC crude oil, OPEC members entered into a production limitation agreement in 1998 intended to reduce production in an attempt to maintain stable prices through the end of the decade. WORLD PETROLEUM SUPPLY/DEMAND BALANCE METHODOLOGY Given the projected outlook for petroleum demand, a world petroleum balance can be derived by balancing the projected availability of crude oil and other petroleum supplies from non-OPEC suppliers against anticipated OPEC crude oil production. This methodology assumes that non-OPEC suppliers will produce to their maximum capability in the longer term. The detailed supply balances and projections are shown in Tables III-1 through III-3. WORLD PETROLEUM SUPPLY/DEMAND BALANCE FORECAST While economic growth will continue and petroleum demand will be robust, OPEC crude oil requirements are expected to decline in the near term due to the rapid increases in non-OPEC output and other supplies through the end of this decade. The Asian downturn will have a particularly negative effect on demand over the next several years. As a result, short term upward price pressure should be non-existent. C-8 In the longer term, increasing demand and a slower rise in non-OPEC output will allow OPEC countries to once again regain market share (Figure III-2). We expect that future OPEC capacity will be sufficient to accommodate our forecast of increased crude oil demands at the forecast price levels. We anticipate that most of this increased OPEC production will come from the large reserve-base countries in the Middle East and Venezuela. Our forecast also is predicated on non-OPEC supplies increasing to the levels shown in our balances (Table III-2) with OPEC supplies expanding at a rate such that OPEC is able to operate between 90% and 95% of its production capacity. [GRAPHIC OF FIGURE 111-2-WORLD CRUDE PRODUCTION] C-9 Figure III-3 shows our forecast for OPEC crude oil production, expected maximum productive capacity, and the implied utilization rate of this capacity. The lower line represents capacity utilization of 80%. When the utilization rate is high, upward price pressure is likely to result. On the other hand, if production requirements fall to below 80%, as occurred during the early 1980s and again in 1998, then crude prices tend to be volatile and weaken significantly. Currently, production requirements are below 80% and we expect them to remain at these levels through this decade, improving only beyond that point. [GRAPHIC OF FIGURE 111-3-OPEC CRUDE PRODUCTION] Our present assumptions regarding individual OPEC country production capacities over the forecast period are shown in Table III-4. Capacity expansion plans are constantly changing depending on pricing trends, budgetary considerations and financing availability. Saudi Arabia's plans over the last few years have been moderated strongly due to budgetary considerations and our outlook reflects a conservative growth pattern for total capacity. Saudi Arabia is concentrating on capacity of highest value crudes. We believe Saudi Arabia will try to maintain extra capacity relative to total OPEC requirements as a buffer to potential political events. Due to the increase in demand and easing non-OPEC production increases in the outer years, it may eventually become more difficult for Saudi Arabia to achieve the desired buffer level, tightening the market and increasing OPEC utilization. We have reflected this in our forecast. C-10 Purvin & Gertz uses these production capacities, along with anticipated OPEC production quotas, as a guideline to determine the projected production of each country. Historically, output from many OPEC countries (with the exception of Saudi Arabia, Kuwait and the UAE) has exceeded the quota levels (Figure III-4). OPEC crude production is being constrained in the short term by agreements to cut production, rather than new quotas. In March 1999, OPEC (excluding Iraq) agreed to cut production to 22.965 million B/D. OPEC appears to be producing very close to these targets.

C-15 IV. U.S. ENERGY AND PETROLEUM DEMAND This section analyzes regional U.S. refined product supply/demand balance trends and resulting refining operating patterns. In the U.S., petroleum is the dominant fuel (38%), but its market share is being slowly eroded. However, since the U.S. economy is so highly developed, shifts from one energy source to another occur very slowly (Table IV-1). Gas and solid fuels each have about 25% of the energy market. Gas is regaining market share lost during the 1980s as it was precluded from being used in new large boilers, so coal and nuclear energy captured a larger share of the market. Hydropower's share is only about 2%, and little potential growth remains. Petroleum's share of the market will continue to erode, primarily since growth in vehicle fuel use is being constrained by higher overall fleet efficiencies. Gas is forecast to show the strongest growth as more gas becomes available. Residual fuel oil and thermal distillate use have already been reduced to practical minimums, so gas for heating can only increase with new demand growth. Nuclear power is limited by regulations and financial problems, but it accounts for 8.5% of the total. UNITED STATES PETROLEUM DEMAND Demand in 1990 showed a decline for the first time since 1983. This resulted primarily from the effects of the recession, which was significantly worsened by the effects of the Mideast crisis. The trend continued through 1991 as the economy had not staged a significant recovery during that period. However, since 1991 refined product growth has averaged over 1% annually. Growth from 1995 to 1998, in fact, averaged almost 1.8% for a gain of near 1 million B/D. Initial 1998 data indicate a small 0.3% gain. However, adjustments will bring this figure closer to 0.8%. The reasonably strong growth, despite several years of mild weather, reflects the continuing strong economy. Gasoline demand has been particularly strong recently due to low prices and stagnant efficiency gains.

Purvin & Gertz expects growth in overall distillates to average near 2% over the next decade, before slowing to about 1.5% through the 2010 to 2015 period. Distillate growth reflects strong gains in on-road application. Gasoline demand growth is now expected to average 1% through the forecast. Travel should increase in the short term as retail prices remain low relative to the peaks in 1997. However, we now expect new technology to influence efficiencies beyond 2005. Beyond the short term, travel will continue to increase by near 2%. Demand per capital gains for gasoline are now expected to decrease over the forecasted period, largely as a result of efficiency improvements and continuing increases in per capita miles traveled. Our forecast now anticipates new car efficiency to improve over the forecast as a result of technology changes. Kerosene/jet fuel demand growth should show some of the strongest rates for all products averaging nearly 2% for most of the forecast. Residual fuel oil demand continues to fall averaging 0.5% decline for the forecast period. Demands for all other products, including other refined products and natural gas liquids, are expected to increase at a rate of 1% through out the forecast, with natural gas liquids showing the largest gains. Purvin & Gertz expects residual fuel demand to continue to decline over the forecast. U.S. MOTOR FUEL DEMAND FORECASTS METHODOLOGY There are three primary driving forces behind motor fuel forecasts -- the extent of travel, the fuel efficiency of the fleet, and the types of fuels used in vehicles. An additional level of complexity to gasoline forecasts has been added over the last few years with the introduction of oxygenated and reformulated C-17 gasolines. These fuels have different efficiencies than standard fuels and each region of the country has seen varying levels of price impact due to varying volumetric requirements for the new fuels. Assumptions regarding alternative motor fuels also affect the outlook for gasoline demand within the time frame of this forecast, and trends also vary by region of the country. Therefore, gasoline demand forecasts must account for the changing qualities and regional differences. The first step in calculating vehicle fuel demand is a projection of annual vehicle miles traveled (AVMT) by PADD. Historical AVMT were broken down into commercial (buses and multi-axle trucks) and private (automobiles, two-axle trucks and motorcycles) categories. AVMT in each category were correlated to population, fuel price, and per capita income. These correlations were used to project miles traveled by PADD based on expected changes in the three variables. Vehicle mileage was considered on a PADD and vehicle category basis. Historical mileage for automobiles and two-axle trucks was calculated using aggregated AVMT and fuel data. Correlations of future mileage of those two vehicle classes were prepared based on projected changes in new vehicle fleet mileage, scrappage and replacement rates, as well as factors accounting for the difference between mileage measured by EPA methods and experienced by on-road vehicles. Projected AVMT in the private and commercial sectors was desegregated into the five vehicle types. The projected AVMT by vehicle type, combined with projected mileage by vehicle type, resulted in the total fuel requirement. Motor vehicle fuels have been grouped into three categories -- gasolines (conventional and reformulated), distillate fuels, and alternative fuels (methanol, electricity, LPG, and CNG). Cars and two-axle trucks are projected to use mostly gasoline though there is a small proportion of diesel and alternative fuel use. Motorcycles use only gasoline. Buses and multi-axle trucks use significant amounts of both gasoline and diesel fuel. Fleet vehicles in that class may use alternative fuels. The projected proportions of each type of fuel by vehicle class were combined with the total fuel requirements to determine fuel use by type. From the forecast of key transportation variables, gasoline consumption in the U.S. is projected to increase at a moderate pace in the longer term. Purvin & Gertz expects the annual growth rate to average about 1.0% over the next ten years, slowing to less than 1% by the end of the forecast period due to moderating price increases, lower population growth, economic effects and efficiency gains. Underlying demand changes over recent years have been altered significantly by the rapid increase in popularity of low MPG utility vehicles and trucks, which expand the demand for gasoline as miles traveled increases. Also, the lack of government initiatives increasing the required MPG for new vehicles has resulted in stagnation of average vehicle efficiency in recent years. However, Purvin & Gertz expects vehicle technologies now emerging to result in higher efficiency in the future, as discussed below. REGIONAL TRAVEL Conforming to Federal Highway Administration (FHA) definitions, vehicles are grouped into passenger cars, light-duty or double-axle trucks, motorcycles, medium and heavy duty or nondouble-axle trucks, and buses. The breakdown of miles traveled into these vehicle groups is necessary to distinguish the different fuel requirements by each group. Using state averages of travel by each type of vehicle, miles traveled are grouped by PADD. The forecast of regional vehicle mileage uses motor fuel prices, population, per capita income, and characteristics of the vehicle stocks to statistically measure past variations in travel corresponding to changes in each of the variables. Each of the regions possess different demographic and economic trends that influence travel patterns for the forecast period. Population growth obviously has a very strong influence on the number of miles traveled on U.S. roads and highways. The table below reviews the estimated historical data and our projections for population growth. The forecasts are prepared on a state-by-state basis and are generally consistent with U.S. government forecasts. Population growth is expected to decrease moderately in the outer years. C-18 Per capita income (PCI) is also a significant factor affecting the level of travel. Over the last five years PCI has been growing strongly as the economy improved from the recessionary trends of the early 1990s. This has contributed to a significant increase in miles traveled. PCI has been a rather erratic variable, but we expect it to average about 1.2-1.3% over the forecast period. Recent levels have been as high as 2%. The average fuel price in each PADD is forecast consistent with our outlook for crude and product prices. The forecast also takes into account changes in prices in specific regions related to changing gasoline specifications under the expected environmental restrictions. With the price collapse of 1998 and relatively mild recovery of prices, we expect a very strong impact on miles traveled in the near term. Key indicators lead to positive growth for miles traveled throughout the forecast. We expect average growth of about 2.7% until the end of the decade. With prices stabilizing and population and PCI growth subsiding, we expect longer term growth in vehicle miles to subside to the 1.7% range in the outer years. Demographics and economic factors come to bear on the regional forecasts as do the differing prices of fuels in each region, particularly as influenced by the regional diversity in requirements for the new fuels of the future, whether gasoline or alternate fuels. VEHICLE EFFICIENCIES Having now projected the extent of vehicle travel, it is necessary to analyze how efficiently each vehicle group uses the motor fuel. Historical and projected vehicle fuel efficiencies as miles per gallon (MPG) were developed on a PADD-by-PADD basis. The fleet average is based upon the replacement rates of new cars for the old vehicles. For autos and double-axle trucks, the rate of new vehicle sales, plus the scrappage rate of old vehicles, were combined to calculate the replacement rate. Replacement rates are the ratio of new registrations to total vehicles from forecasts of new car registrations and the resultant auto stock. For double-axle trucks, the replacement rate is estimated using the auto replacement rate. This is justified because both vehicles have similar characteristics and data on double-axle trucks was insufficient to compute a similar measure. For motorcycles, nondouble-axle trucks and buses, it was assumed that the new vehicle characteristics are the same as old vehicle characteristics. Average fleet efficiency has not improved significantly in recent years with the American consumers demanding larger engines and more power. In addition, the move toward SUVs and light trucks has been dramatic. While these trends are generally expected to continue for the foreseeable future, Purvin & Gertz expects emerging vehicle technologies to provide an upward boost to auto efficiency in future years, even without new government mandates. The most important of these is the gasoline direct injection (GDI) engine. These engines use lean-burn technology and precise fuel control to provide efficiency gains of 15-20% in typical vehicles. Several manufacturers are now poised to commercialize GDI technology. However, the lean-burn mode results in much higher nitrogen oxides (NOX) emissions than conventional engines. Current emissions control catalyst systems cannot reduce NOX sufficiently due to the high sulfur level in today's gasoline. Thus, GDI is unlikely to penetrate the fleet until gasoline sulfur is reduced significantly. The recently proposed reduction to 30 ppm (average) by 2004 should enable GDI technology to begin to enter the fleet. As the engines gain consumer acceptance, penetration should increase rapidly. As a result of GDI and other technological advancements, average light-duty vehicle fleet efficiency is projected to increase by about 20% from 2005 to the end of the forecast period. Our forecast of new car efficiency changes results in an EPA based average fuel efficiency in the year 2010 at about 30.4 MPG's and 34 in 2015 versus about 28.7 currently. Purvin & Gertz expects new truck efficiencies to gain modestly as well. When translated to the fleet calculation, they yield about a 21.6 fleet MPG average in 2015 versus about 19.3 currently. NON-HIGHWAY FUEL USE ADJUSTMENTS To accurately project gasoline and diesel fuel consumption, the data must be adjusted to account for the reporting differences between Federal Highway Administration (FHA) data and Department of Energy (DOE) C-19 numbers. The FHA collects consumption numbers on the basis of the federal tax revenues collected. This is different from the data collected by the DOE, which include all gasoline supplied for both highway and non-highway use. Diesel and special fuels consumed for highway use are collected by the FHA. Adjustments have been made to reflect non-highway use. Also, comparing FHA and DOE growth rates on a total U.S. basis does not show dramatic differences except where significant secondary inventory shifts might be effecting the primary demand data. When comparing rates by PADD, however, the differences can be large, reflecting transfers between regions. We have developed a correction method that incorporates this and allows FHA data history and forecasts to be converted into a DOE basis by PADD. ALTERNATIVE FUELS Much discussion and concern recently has focused on the possible effects of alternative fuels on gasoline demand. Obviously, significant penetration of non-gasoline vehicles into society would have very important implications for refiners. Reduced gasoline demand would change the outlook for capacity requirements. If rapid changes occurred, there could be a negative effect on industry profitability. Our analysis still indicates that alternative fuels are not likely to have a significant effect on gasoline demand until late in the next decade, and the extent of impact then is by no means a clear issue at this point. The primary alternative fuels presently at issue include methanol, CNG, LPG, and electricity. LPG (primarily propane) contributed about 41,000 B/D to the transportation sector in 1997, and this is projected to grow to about 55,000 B/D by early in the next decade. Though CNG is currently in use, its application is likely to be restricted to fleet vehicles for some time. Fleet vehicles, however, represent only a small portion of the overall fleet, and the effect on gasoline demand, therefore, would likely be small, unless full conversions were made. A major portion of CNG use is also displacing diesel fuel rather than gasoline. We also expect methanol usage to be inconsequential, taking into account such factors as toxicity, logistics and economics. The West Coast has been a leader in mandating alternative fuels. In 1990, the California Air Resources Board (CARB) mandated zero emissions or electric vehicles (ZEV's) to comprise two percent of new vehicle sales by the 1998 model year increasing to ten percent by 2003. Technological progress has not met the CARB expectations and only a few hundred ZEV's have been licensed for highway use in California. CARB has delayed and modified the ZEV mandate. Due to a failure for auto manufacturers to produce a viable electric vehicle, mandates for 1998 through 2002 were suspended. Furthermore, the program has been modified to allow for production of equivalent zero emissions vehicles (EZEV's) which have emissions profiles similar to the generating stations used to power electric hybrid electric vehicles (HEV's). The fuels which would power EZEV's or HEV's are not limited but they could include petroleum-based fuels manufactured in the California refining system. Future sales of ZEV's and other alternative fuel variants will depend on the ability of auto manufacturers to devise products incorporating those emissions characteristics while preserving performance and value parameters demanded by the auto-buying public. U.S. GASOLINE DEMAND Gasoline consumption declined from a high of about 7.4 million B/D in 1978 to only 6.5 million B/D in 1982, but this decline was reversed as gains in vehicle miles traveled began to outweigh the mandated fuel efficiency improvements, and as the fuel standards were relaxed. Because of relatively stable energy prices, the percentage of disposable income required to pay fuel bills began to shrink as incomes grew. Consequently, consumers had more money to spend on lifestyle improvement and they chose to purchase larger, higher-performance automobiles rather than smaller cars. In combination with increased driving, this caused gasoline consumption to grow through the early 1980s. The drop in prices in 1986 resulted in a particularly strong increase. However, beginning in 1989, efficiency improvements outpaced increased driving. The significant impact of briefly increased prices and the economic downturn in 1990 and 1991 is particularly evident in the driving trends over that period. C-20 Large gains in prices due to the Gulf War caused US motor gasoline demand growth to drop sharply in the early 1990's. As prices equilibrated from the highs of the war, demand recovered 2.5% in 1995. In 1996 strong overall petroleum demand tightened the market causing prices to rise. Counterbalancing some of the increases in prices were consumer spending increases and as well as a choice for larger more inefficient sports utility vehicles versus smaller passenger cars. The price collapse in 1998 elevated demand growth to above 2%. We continue to see the near term growth around 2% as prices slowly recover. By 2015 motor gasoline demand growth is projected to drop to less than 0.5% which will result in higher efficiency in the outer years. This forecast evolves on new vehicle technology.

Demand turned up in 1992 and 1993 due to the economic recovery and rose sharply in 1994 (Table IV-2) due to the severe winter. The unusual weather in 1994 resulted in only modest gains in 1995 for the winter fuels, but the extended cold waves in early 1996 led to a recovery. Demand growth in 1996 averaged close to 5% with strong gains in diesel as well as heating oil. In 1997, the winter was significantly milder, resulting in an increase of only 2%. In 1998 the mild weather caused by El Nino effects resulted in demand rising only 0.2%. Distillate fuel oil market growth in the future will come mostly from increases in transportation consumption. Diesel penetration of the personal automobile fleet will be negligible. However, continued economic growth will increase the need for trucking and, therefore, diesel fuel. Bunker use of distillate has been growing steadily, but should see more moderate increases in the future. The continued growth in distillate demand will be primarily due to the rise in transportation demand. Whereas distillate used for transportation has been growing rapidly, market shares of distillate in most other sectors have declined. The loss of market for distillate fuel oil has been particularly noticeable in the residential sector, Consumption of natural gas and electricity has pushed out demand for distillate. A strong winter in 1996 revitalized the sector but was quickly gone with the El Nino effect in 1998. Demand declined 8% to 390 MB/D in 1998. Longer term, we still expect modest declines in this sector. Consumption of distillate in the industrial sector (combining industrial, oil company and electric utility) dropped to about 224,000 B/D in 1997, (the last year for which full sector information is available). This compares to a high of 460,000 B/D in 1979. The drop has been due to fuel substitution. Consumption in these sectors has stabilized somewhat since the economy is again growing, but we do not see foresee major gains in these sectors through the forecast. The use of distillate fuel oil in the commercial sector also declined through the early 1990s. It has continued to fall to 210,000 in 1997. Consumption in the other sectors (farm, military, off-highway, and miscellaneous) has also leveled off in recent years, and only modest growth is anticipated. In October 1993, refiners began to produce diesel fuel with a much lower sulfur content from in the on-highway market. These fuels are required to contain 0.05% sulfur or less. Only about 55% of the distillate pool is required to meet these more stringent specifications, as it is applicable to on-highway product. Even so, many refiners are able to produce 100% of lower sulfur material. Low sulfur diesel is penetrating other sectors, such as farming and off-highway diesel use, as a result of logistic constraints as well as strong marketing. In fact, total U.S. low sulfur diesel demand now represents about 66% of distillate use while the on-highway portion is only 56% of total consumption. Purvin & Gertz forecasts that low sulfur diesel market share will grow due to the increasing demand for diesel fuels in the transportation sector, rising to about 70% of distillate over the next 10 years. This growth in transportation demands combined with the growth in other sectors will result in low sulfur demand growing from 2.3 million B/D in 1998 to over 2.4 million B/D by the end of the decade. Low sulfur diesel growth should exceed 2% annually over the next decade, but we expect it to taper closer to 2% by the end of the forecast period. High sulfur distillate demand in contrast remains stagnant, rising from 1.17 million B/D in 1998 to 1.21 million B/D by 2000, and to only 1.35 million B/D by 2015. Low sulfur diesel demand has grown more rapidly than expected since its introduction. This is attributed, at least partially, to use of non-taxable fuels in this market. This problem now has been alleviated by fuel dyeing for monitoring purposes. Most of the distillate fuel oil consumed in this country is produced domestically, but imports have been averaging about 200,000 B/D under normal conditions. This material is primarily imported from the Caribbean to the East Coast, but Canada and Africa are also major supply sources. Due to the somewhat more robust growth of distillate demand relative to gasoline, refinery production of distillate relative to gasoline will C-23 continue to increase in the future. We also expect imports to remain generally proportional to demand increases. The introduction of low sulfur diesel fuel has made it difficult for some exporters to meet these requirements. Nevertheless, Canada and Virgin Island imports should remain proportional to demand. In addition, European specifications are being modified to reduce sulfur levels. U.S. AVIATION FUELS Growth in demand for aviation fuels has been one of the strongest among the refined products, led by commercial kerosene-type jet fuel. Aviation gasoline usage has held steady over recent years and averages only 20,000 B/D. Military consumption of naphtha-based jet fuels had been steadily declining due to the downsizing of the military. The military began the phase-out of JP-4 in 1992 and JP-4 was totally phased out by the end of 1995. This switch substantially increased the demand for kerosene-based fuels over the phase-out period but the underlying growth patterns have now become transparent. Kerosene-type jet fuel demand grew from about 800,000 B/D in the early 1980s to a peak of 1.34 million B/D in 1990, representing an average growth in excess of 5%. A decline was noted in 1991 due to the Middle East crisis and the downturn in the economy, but a strong growth was been evident during the military switch. Demand in 1997 reached a record high of 1.6 million B/D. The 1998 figures currently indicate a decline, which is inconsistent with other usage indicators. This is attributed to gross underestimates of imports by the EIA that we expect to be corrected. Other forecasts take fares into account. We also expect strong growth to continue throughout the forecast with increasing airline travel. We are looking for average growth rates in the 2.0-2.5% range over the next 10 years, declining to about 1.5% by 2015. The U.S. still produces a major portion of its jet fuel requirements, but there is some trade. Except during the 1989-1990 Gulf Crisis, net imports have averaged about 50,000 B/D, with exports ranging from 25,000-40,000 B/D. Most of the imports come into PADD I, through increases in PADD V are adjusted PADD III accounts for the bulk of the exports. U.S. RESIDUAL FUEL OIL Beginning in the late 1960s, the demand for residual fuel oil began to escalate rapidly as many of the utility companies burned residual fuel oil in much greater quantities because of its availability and low cost. In the 1970s, natural gas was in short supply and residual fuel use was high. The demand for residual fuel in the utility industry peaked in 1977-1978 at about 1.6 million B/D, but declined to only 400,000 B/D in 1985. Residual fuel oil demand has continued to decline and a particularly strong drop occurred in 1995, as gas availability forced reductions in fuel consumption in Florida and other areas. The 1995 decline in residual fuel use was 16.6%. Actual sector data is available through 1997. The data shows utility usage as the major contribution to the decline. With lower prices relative to natural gas utility demand strengthened in 1997 and 1998 relative to past years. Purvin & Gertz expects this trend to reverse again in the forecast. Another major use of residual fuel oil is in the transportation sector for vessel bunkering. Consumption in the transportation sector grew rapidly from 260,000 B/D in 1973 to nearly 600,000 B/D in 1980. Much of this growth in bunker fuel demand was due to U.S. price controls, which caused U.S. bunkers to be much cheaper than world market prices. Consequently, whenever possible, foreign ships bunkered in U.S. ports. When crude oil price controls were lifted, U.S. bunker fuel demand declined to 400,000 B/D. Since that time, bunker use has fallen to the 315,000 B/D range and appears stabilized at this level. Increased petroleum imports into the U.S. should cause bunker use to increase gradually over the forecast period. The use of residual fuel oil in the industrial sector was 855,000 B/D in 1973, but since then, consumption declined near 120,000 B/D. This level is the lowest since 1991 when demand was 126,000 B/D. This decline can be attributed to fuel switching. Purvin & Gertz expects the decline in utility demand to continue in the years ahead, however, at a much slower rate. Commercial demand accounts for only a small portion of total demand and this demand should C-24 also fall over the forecast. The declines in utility demand and the small amount of industrial demand results in the transportation sector's outlook becoming the dominant determinate on demand for residual fuel oil. Our forecast anticipates that bunker demand will continue to rise slowly with the growing amount of international trade. Longer term, this growth, combined with the rise in industrial demand, will result in residual fuel oil demand declining slightly on an annual basis during the next decade. Of the total demand, about 25% is currently being imported. The Caribbean is the major supply source, but significant, though decreasing, volumes of low sulfur residual fuel oil are imported from Algeria and Brazil. We expect imports as a percentage of demand to decline slowly throughout our forecast. Gulf Coast refiners use the export market to balance their operations. PADD III has two options: it can either move material to other PADDs or export it. Since the East Coast primarily uses low sulfur material, excess PADD III high sulfur material must be exported. Presently, most of these exports are into the Western Hemisphere blending market and to Caribbean markets such as utilities. This is a sensitive balance and even slight excesses of supply relative to regional demand can result in the need to export beyond the Western Hemisphere. This results in depressed prices in the Gulf Coast, as was seen throughout the Mideast crisis when refiners were forced to run the higher sulfur heavier crudes, and early in 1997 when conversion unit problems increased supply. In 1998, export demand increased due to hydropower deficiencies and the market strengthened. Low production resulting from lighter crude slates and increased conversion has kept the market strong in 1999. PADD V satisfies its imbalance from the production of residual fuel oil by exporting its surplus. This surplus has, however, significantly decreased over the years and exports have dropped even further as new coking units come onstream. Total U.S. exports dropped to $100,000 B/D in 1996 from peaks of well over 200,000 B/D during the Iraqi war when U.S. refiners were running heavier crudes, and residual fuels had to be exported out of the Western Hemisphere. they increased to 137,000 B/D in 1998 due to the high export demand. However, we expect them to drop back to the 100,000 B/D range in the forecast. PADD II is essentially in balance, but some low sulfur residual fuel oil is moved up from the Gulf Coast, while small periodic surpluses of high sulfur residual fuel oil moved down to PADD III. PADD I is the major deficit market in the U.S. Therefore, it balances its market demand by either importing or transferring material from PADD III. Generally, PADD III serves the southeastern portion of PADD I, whereas the foreign product is largely moved to the Northeast market. U.S. ASPHALT Asphalt demand in the U.S. is mainly driven by paving requirements for road construction, resurfacing, restoration, and maintenance. In fact, paving activities consume nearly 90% of the asphalt demand in most years. Roofing requirements consume the rest of the demand. The Asphalt Institute conducts an annual survey of asphalt producers in North America which provides information on the split between paving and non-paving demand. Asphalt demand peaked in 1990 at about 485,000 B/D, but dropped off to about 450,000 B/D in 1991/92 as a result of the recession. Demand varies from year to year, and exceeded 500,000 B/D for the first time in 1997 (Table IV-2). Asphalt demand is affected by the economy, since roofing asphalt demand is a function of home building and the replacement market. Paving asphalt demand is dependent on government funding for road building and repair so it varies with government policy. Since the outlook for the basic drivers (the economy and transportation) is positive, we expect asphalt demand to increase over the forecast period, with normal year to year fluctuations. The U.S. is basically self-sufficient in asphalt but about 30,000 B/D are annually imported, primarily from Venezuela. PDVSA is a large producer and marketer of asphalt in the U.S. and brings in some supplies from Venezuela. Purvin & Gertz does not expect a significant increase in imports of asphalt. C-25 U.S. COKE Coke consumption has increased along with the increase in production of marketable coke. In addition to the marketable coke, another 220,000 B/D is produced and consumed in the refineries. A portion of the coke is low sulfur and can be used for anodes for the manufacture of aluminum, but most is high sulfur and is used as fuel or exported. Coke can be used directly for burning in cement plants and blended with coal for boiler fuel. PADD II is the largest consumer of coke followed by PADD III. PADD II consumption, accounts for about 45% of the total usage. There are a number of coal fueled utility plants in PADD II. The big increase in consumption in PADD III in 1992 was related to the start-up of a co-generation plant that uses coke as fuel, but consumption has dropped back off. As more cokers are brought onstream, coke will be marketed to the extent possible in the U.S., with the balance exported. U.S. OTHER PRODUCTS Production of other products is now about 2.2 million B/D and growing. Most of these products are consumed in the U.S., but a significant portion of the coke production is exported, as discussed earlier coke shown in the table below represents total coke produced. Other product demand has grown very strongly over the years. In 1997, growth averaged near 3%, rising to 4.7 million B/D. This includes NGL's and all other non-major fuels products. In 1998, demand fell to 1996 levels of 4.6 million B/D reflecting mild weather, but we expect demand to rise by about 1% per year over the forecast.

HEAVY CRUDE OIL AVAILABILITY There should be adequate supplies of heavy crude available to the Upgrade Project because heavy crude production is concentrated in the Western Hemisphere and Purvin & Gertz expects production to increase substantially over the life of the Upgrade Project. In recent years, heavy crude production has been increasing rapidly, particularly in Venezuela, Mexico and Canada, whereas exports to Western Europe and Asian have not increased significantly. The increased Canadian production has been utilized in refineries in the U.S. Midwest (PADD II) and Mountain Region (PADD IV). Most of the increase from Mexico and Venezuela has been placed in refineries on the U.S. Gulf Coast (PADD III), where the Upgrade Project will be located. Availability of larger quantities of heavy crude has led to the addition of deep conversion equipment (such as cokers) to minimize the yield of residual fuel oil in the refining process. Expected future increases in heavy crude production in Mexico and Venezuela are causing the heavy oil producers to seek out joint ventures or crude supply arrangements, such as the Upgrade Project, to process these crudes. Several others have been announced and more will likely be forthcoming. HEAVY CRUDE OIL PRODUCTION Heavy crude production is concentrated in the Western Hemisphere. In 1998, Latin America produced 3.9 million B/D of heavy crude out of a total worldwide production of 8.9 million B/D. The U.S. (866,000 B/D) and Canada (825,000 B/D) contributed 1.7 million B/D, raising the Western Hemisphere total to 5.6 million B/D which represents over 60% of the world's 1998 heavy crude production. About 2.0 million B/D of heavy crude was produced in the Middle East, with the balance scattered throughout the rest of world. Heavy crude production by region is shown in Table V-1 and summarized below.

Exports by destination for 1998 are shown in the following table.

Mexico also produces a medium (32(degrees) API) sour crude (Isthmus) and a very light (39API) sour crude (Olmeca). MEXICAN CRUDE OIL PRODUCTION Total crude oil and condensate production has increased rapidly since the first wells in the Chiapas-Tabasco (Reforma) were brought onstream. A high level of drilling activity in 1978 resulted in production from the prolific fields in the Bay of Campeche. Total crude oil reserves that were estimated to be 25.6 billion barrels at the end of 1978 have been officially estimated at 48.8 billion barrels as of January 1, 1998. Crude production in Mexico increased rapidly from the mid 1970s through the early 1980s. From 1982 through 1996, production averaged about 2.7 million B/D and did not reach the 3 million B/D mark until 1997 (Figure V-1 and Table V-2). Even though total production did not increase significantly over the 1982/98 period, there was a significant shift in quality. Prior to 1982, most of the production was light sour (Isthmus), but heavy sour (Maya) grew rapidly starting in 1979, and exceeded 1.0 million B/D in 1982 for the first time. Maya production has increased slowly since then and was 1.61 million B/D in 1998. [GRAPHIC OF FIGURE V-1-MEXICO CRUDE PRODUCTION] C-28 For the short term, Mexico has agreed to reduce exports to assist the OPEC producers in reducing excess supplies of crude oil. However, in the longer term, exports of Maya will increase (Figure V-2). [GRAPHIC OF FIGURE V-2-MEXICO CRUDE EXPORTS] In 1988, Mexico began segregating a very light sour crude (Olmeca) and production of Olmeca peaked at 578,000 B/D in 1996, declining slightly to 554,000 B/D in 1998. At the same time, production of medium sour crude (Isthmus, 32(degrees)API) declined from about 1.7 million B/D in 1982 to below 900,000 B/D in 1991. Production of Isthmus has remained in the 800,000 to 900,000 B/D range since 1991. Production of Olmeca and Isthmus is forecast to decline slowly over the next 20 years. Maya Crude Oil Most of Mexico's heavy Maya (22(degrees)API and 3.4%S) comes from the Cantarell field. Within the Cantarell field there are four major fields with total remaining reserves of 14 billion barrels of crude.

Estimated expenditures exceed $1 billion. It is being brought on in stages, with the first train of the plant (300 MM cfd) scheduled for April 2000 and the remaining three trains to be onstream by January 2001. At completion, PEMEX expects production of Maya to increase to over 2.0 million B/D. Mexico exports most of its Maya to the U.S., with the balance shipped to Europe and Asia. While PEMEX prefers to sell its Maya on a term basis, some Maya could be redistributed between markets. This may take 6 months to 1 year to accomplish this since PEMEX generally sells its crude on term contracts. Longer term, PEMEX is likely to have uncommitted volumes of Maya as production is likely to grow faster than PEMEX can find commitments for its crude. C-29 ALTERNATE SOURCES OF HEAVY CRUDE OIL SUPPLY If for some reason heavy crude from Mexico is not available to the Upgrade Project, other heavy crudes are likely to be available. Venezuela plans to increase production of heavy crude and will be looking for outlets for this production. Venezuela would be a logical place for the Upgrade Project to look for heavy crude supplies since it would be a short haul crude. Venezuela crudes are heavier and contain more sulfur than Maya but they can be processed by the Upgrade Project. VENEZUELA Venezuela's reserves are predominantly composed of heavy grade crudes. In 1998, PDVSA had about 75 billion barrels of proved oil reserves, which includes both developed and undeveloped reserves. Developed reserves totaled 17 billion barrels in 1998 of which heavy and extra heavy (less than 10API) crudes comprised approximately 6.5 billion barrels. Venezuela has a broad range of crude oil produced from numerous fields. Such production is categorized by Venezuela into three types: Light: 30(degrees)API Medium: 22-30(degrees)API Heavy: <22(degrees)API Production of the light grade crude oil has been increasing rapidly in recent years due to the market preference for lighter crudes at rates disproportionate to reserves. The medium grade crude classification by PDVSA includes crude predominantly in the 22-25(degrees)API range, and includes the major 24(degrees)API export grades. These Venezuelan crudes have somewhat better distillation yields, lower sulfur content and lower viscosity when compared to most other exported heavy crude oils. The low gravity is exaggerated by the naphthenic quality of the crude, although the metals content is typical of Western Hemisphere heavy crudes. The heavier than 22(degrees)API crudes include Bachaquero light types of approximately 17(degrees)API, the Bachaquero heavy types of approximately 13(degrees)API, the Merey crude oil (16(degrees)API and the even heavier types such as the Boscan 11(degrees)API crude. In order to more rapidly develop its heavy oil reserves in the Orinoco belt, Venezuela is developing a number of heavy oil projects. These projects vary in size from 100,000 to 200,000 B/D, and employ different technologies to produce syncrudes ranging from light sweet (31(degrees)API) to fairly heavy sour syncrude (15(degrees)API). These projects currently include the following: . Conoco has entered in a joint venture with PDVSA (Petrozuata) to upgrade 120,000 B/D of Zuata heavy crude oil (10(degrees)API, 2.7%S) to 104,000 B/D of 20(degrees) to 23(degrees)API high sulfur (2.3%S) syncrude. . Mobil/Veba entered in a joint venture with PDVSA (Cerro Negro), approved in October 1997, to upgrade 120,000 B/D of Cerro Negro heavy crude oil (8(degrees)API) which will be upgraded further at Mobil's Chatmette, LA refinery and in Veba's European refinery system. . Total/Statoil (Sincor) entered in a joint venture with PDVSA to upgrade 192,000 B/D of heavy crude oil (9(degrees)API, 3.4%S) to light sweet syncrude. C-30 . Arco/Phillips/Texaco have entered in a $2.2 billion joint venture Association Agreement with PDVSA (Petrolera Ameriven). In connection with this project, about 200,000 B/D of Hamaca heavy crude oil (9(degrees)API) will be upgraded to 180,000 B/D of 25(degrees)API syncrude. This project is currently on hold pending developments in the energy and capital markets. Arco recently sold its interest in the project to Phillips and the new partners plan to start construction by mid 2000. Venezuela's actual and estimated crude oil production exports and domestic use is shown in Table V-3. Venezuela's crude oil production declined from the early 1970s through the late 1980s to 1.56 million B/D. However, since 1986/87, this trend has reversed and production has doubled to about 3.25 million B/D in 1997 (Figure V-3). Production was down slightly in 1998 and will decrease again in 1999 as a result of Venezuela's agreement with OPEC to cut production. Prior to the recent decline in demand, which prompted the cutbacks by OPEC, Venezuela had announced plans to increase production to 5.5 million B/D by 2008. However, given the OPEC cutbacks, decline in demand and other developments, reaching this targeted production rate will likely be delayed. [GRAPHIC OF V-3-VENEZUELA CRUDE PRODUCTION] In 1998, PDVSA processed for domestic use mostly medium crude (412,000 B/D) and light crude (426,000 B/D) in its refineries. Only about 228,000 B/D of heavy crude was processed. As a result, the majority of heavy crude produced is exported for processing outside of Venezuela. Exports in 1998 amounted to approximately 813,000 B/D, 798,000 B/D, and 445,000 B/D of heavy, medium and light crude oil, respectively (Figure V-4). Since we expect heavy crude production to increase in line with, or slightly faster than the other grades, we believe that heavy crude exports will increase. Medium Venezuelan crude also includes heavy crude ranging from 21(degrees) API to 30(degrees) API with most of the production being of heavier grades. [GRAPHIC OF V-4-VENEZUELA CRUDE EXPORTS] C-31 Since 1989, Venezuela's crude production has gradually shifted to a higher percentage of heavy sour crude. Heavy crude accounted for about 22% in 1990, about 33% in 1997 and is forecast to be about 35% by 2020 (Table V-3). HEAVY CRUDE BALANCES Heavy crude production, indigenous consumption, and exports by destination were analyzed for the historical period of 1990 to 1998 and forecasts were prepared for 1999 to 2020. The major export markets for heavy crude are shown in the following table: MAJOR EXPORT MARKETS FOR HEAVY CRUDE (Thousand Barrels per Day) Projected ----------------------------------- 1995 1996 1997 1998 1999 2000 2005 2010 2015 2020 ----- ----- ----- ----- ----- ----- ----- ----- ----- ----- United States...... 2,335 2,494 2,818 2,885 2,912 3,153 4,367 4,923 5,393 5,500 Canada............. 104 74 79 79 95 96 103 110 118 125 Latin America...... 55 61 86 87 89 90 97 104 111 120 Middle East........ 108 98 80 80 79 79 78 76 75 75 Japan.............. 351 338 343 357 371 386 457 529 550 600 Asia............... 13 15 33 35 35 35 35 35 35 35 Western Europe..... 579 540 541 527 518 506 447 383 315 300 Total............. 3,543 3,620 3,981 4,050 4,099 4,345 5,584 6,160 6,597 6,755 Worldwide heavy crude production declined from a peak of 7.3 million B/D in 1981 to 6.0 million B/D in 1985, but reached a new high of 8.94 million B/D in 1998 (Table V-1). The output of heavy crude in the Middle East during that time period was highly influenced by the level of production in Saudi Arabia and the mix of crude oil grades. The decrease in Middle East heavy crude production in the 1980s was due to a number of factors, including overall market demand, the OPEC quota system, and Saudi Arabia's election to have its production efforts focused on light and medium crudes. Also, as Venezuela strived to maximize light production within its OPEC quota, its heavy crude output declined through 1989 (Table V-3). OPEC producers capable of producing multiple grades of crude oil have an incentive to maximize revenues in periods of constrained production by maximizing production of more profitable light and medium crudes while making production cuts in the heavy crude oils. Saudi Arabia and Venezuela increased their share of total production in 1990-91 in connection with the Gulf War. During the early 1980s, the higher value of Middle Eastern crudes in other markets prevented heavy crudes from penetrating the U.S. market. About 65% of the U.S. heavy crude refining capacity was designed for the low-metals Middle Eastern crudes and, hence was under-utilized in the early 1980s due to the price disparity. Netback pricing arrangements eliminated the disparity and Middle Eastern imports began flowing into U.S. markets in the late 1980s. Imports of heavy crude from the Middle East averaged only 24,000 B/D in 1986, but rose rapidly and peaked at 500,000 B/D in 1991/92. Imports dropped back off during the 1993/97 period. Middle East imports have increased the past two years, with 330,000 B/D of heavy sour crude imported into the U.S. in 1998. Heavy crude imports from sources other than the Middle East increased throughout the 1980s and early 1990s. Imports of Maya increased to the 800,000 B/D range, while Venezuelan shipments increased from approximately 300,000 B/D in 1985 to 900,000 B/D in 1998. Venezuelan exports to the U.S. were stimulated in part by Venezuelan equity ownership of U.S. heavy crude refining assets. Canadian exports, mostly to the Midwest, averaged about 400,000 B/D during the 1990-95 period, but surged to over 724,000 B/D in 1998 when more pipeline capacity became available. Europe and Japan are the only other major importers of heavy crude. Consumption in Japan has remained relatively constant for the last several years. Japan imports 350,000-375,000 B/D, mostly from the Middle East. C-32 Imports of heavy crude into Europe are declining. From a peak of 875,000 B/D in 1992, imports declined to approximately 527,000 B/D in 1998. Most of Europe's imports come from Latin America and the Middle East, but Egypt exports about 50,000 B/D to southern Europe. Over the next several years production of heavy crude will not increase as rapidly as in the recent past. The OPEC cutbacks will cause less heavy crude to be produced in Venezuela and in the Middle East. Canada's plans to increase heavy oil production have also been slowed by the recent crude price drop. However, the crude price is already recovering so the impact of the price drop will be short live. As is illustrated in the following table, we expect heavy crude production to further increase during the 2000 to 2020 period with the major production increases occurring in the following areas.

DIVERSION RISKS There is always some risk that crude from a particular source will be disrupted or diverted from a particular market for any number of reasons: . Weather or other "force majeure." . Infrastructure constraints. . Political interference. . Production changes. . Marketing opportunities. The risks can be minimized by designing in flexibility to use crude from alternative sources. Usually, weather related disruptions are short lived. Similarly, infrastructure constraints like pipeline bottlenecks, etc., can be relieved fairly quickly. Political interference like the Iraqi, Libyan, or Iranian embargoes, last longer and can sometimes be permanent. Decline in production or better marketing opportunities can also be more permanent and structural impediments are generally long lasting. PRODUCTION CHANGES Declines in production can often be anticipated but, if not, the gradual nature of full decline provides time to make alternative arrangements. The Upgrade Project is being designed to run Maya crude. Generally, it is risky to design a facility capable of running only one specific crude particularly if the design crude has a unique set of characteristics. The field could decline, the producer could refuse or be unable to deliver, etc. However, in this case, the risks are reduced since Mexico has a very active program underway to significantly expand Maya production. In addition, Venezuela is also expanding its heavy crude production as well. However, a facility designed to handle Maya crude (22API) can easily substitute other heavy crudes like Neutral Zone crudes or many Venezuelan crudes since they are generally lighter and have less metals and sulfur. MARKETING OPPORTUNITIES Producers continuously analyze market opportunities to seek out the highest possible netbacks consistent with maximizing production and hence revenue. Even so, most crude today is sold under contract so that efficient transportation arrangements can be made and crude will flow regularly from producer to consumer. In this environment, crudes tend to flow to the highest value market and the flow patterns are fairly stable. Stability is often disrupted by sudden increases (decreases) in supply in a producing region. For example, the rapid increase in crude supplies in the Atlantic Basin (North Sea, West Africa, Latin America) is causing flow pattern changes. In recent years, Mexico, Venezuela and Canada have increased production of heavy crude and have placed as much as possible in the U.S. (particularly in the U.S. Gulf Coast). These crudes have reduced requirements for crude from the Middle East. Mexico and Venezuela have a strong incentive to place the crude in the U.S. because other markets are much farther away so the shipping cost would reduce the netbacks to the producers. Furthermore, the refining industry in most other regions is not configured to handle heavy sour crude. In 1997, PEMEX exported 843,000 B/D of Maya to the U.S. which accounts for 84% of its heavy exports. Northwest Europe, for example, has a large surplus of light sweet crude coming out of the North Sea. Refineries in this region have no incentive to invest to run heavy crude when more than adequate supplies of light sweet crude are available. In addition, the requirement for low sulfur products and the availability of natural gas from the North Sea and Russia reduces the need for residual fuel oil, particularly high sulfur resid. Heavy sour crudes yield a much larger percentage of high sulfur resid than light sweet crude. C-39 Refineries in the Mediterranean region were designed to handle some heavy sour crude from the Middle East. However, a similar requirement for low sulfur fuels is reducing the demand for crudes which yield high sulfur resid. Declines in resid consumption is being expedited by the significant increases in availability of natural gas from Africa, Russia and the North Sea. Asia is choosing lighter crudes from Africa and the Middle East for similar reasons. Product specifications are requiring lower sulfur products and refiners are better able to meet these requirements by selecting lighter crudes and minimizing investments. Japan is the major market for heavy crude as their refineries were configured to handle heavy crudes from the Middle East. Even so, Japan is resisting pressure from Middle East producers to use more heavy crude. The small quantities of heavy crude from Mexico and Venezuela that are exported to Europe and Asia are primarily for asphalt manufacture. These crudes make good asphalt and are highly sought for these properties. However, the quantities are limited and growth in demand will be moderate. Most of Mexico's shipments to Europe go to Spain under a state to state arrangement between PEMEX and Repsol of Spain with smaller quantities going to Portugal. Most of Venezuela's heavy crude shipments to Europe go to Germany where PDVSA has ownership in a refinery. U.S. CRUDE OIL IMPORTS Table VI-1 summarizes total PADD I, II, and III heavy sour crude oil imports for 1994 through 1998. The tables demonstrates that the Gulf Coast (PADD III) is the largest U.S. sour crude oil and heavy sour crude oil import market. The table also illustrates that PEMEX's market share for crude oil and heavy sour crude oil in particular is substantial, particularly in the Gulf Coast region. In the Midwest region (PADD II), where Canadian crude oil has a significant transportation advantage over Mexican crude oil, PEMEX's market share is small. PEMEX was the second largest supplier of heavy crude oil to the United States with a 29% share of imports into the combined U.S. East Coast (PADD I), U.S. Midwest (PADD II) and U.S. Gulf Coast (PADD III) regional markets in 1998. Venezuela was first with a 33% share. The PADD (Petroleum Administration for Defense District) designation is the terminology used to define the various crude oil refining and marketing regions of the United States. The U.S. Rocky Mountain (PADD IV) region and the U.S. West Coast (PADD V) region are not considered competitive markets for Mexican crude oil due to logistical and competitive advantages possessed by Californian and Alaskan production. Sour crude imports for 1996 through 1998 by source are shown in Table VI-2. Crude runs by refinery for 1996 and 1997 are shown in Tables VI-3 and VI-4, respectively. MAJOR CUSTOMERS PEMEX's high U.S. market share is a result of increasing availability of heavy sour crude and its proximity to the market, as well as an effective marketing strategy. PEMEX is entering into agreements with refineries capable of efficiently processing heavy sour crude oil. The first joint venture coker project was with Shell at Deer Park. In late 1996, a 60,000 B/D coker came onstream. An announcement has been made that the coker will be expanded and Maya crude runs will be increased at Deer Park. PEMEX has also entered into a 100,000 B/D crude supply agreement with Coastal for Aruba. Purvin & Gertz expects about 220,000 B/D of Maya crude to be run when the new coker is completed in 2000. The Upgrade Project at the Clark Port Arthur refinery calls for about 200,000 B/D of Maya to be run at this facility. Recently agreements have been reached with Exxon to increase Maya runs to 65,000 B/D when the coker is expanded at Baytown and with Marathon to run 90,000 B/D when its new coker is completed. Long term contracts for Maya for 2002 now total 675,000 B/D. Table VI-5 lists the primary customers for PEMEX in the U.S. ranked by total barrels of heavy crude oil imported into PADDs I, II, and III over the 1994-98 period. As the table illustrates, customers of PEMEX together represented around 800,000 B/D of the heavy crude oil imports into the U.S. in 1998 and this will increase in the future. C-40 STRUCTURAL IMPEDIMENTS Structural constraints which would reduce the risks of diversion can either be physical (i.e. the refinery design does not allow heavy sour crude to be run), ownership (for example, Venezuelan crude will be selected over Maya if unable to run in refineries owned by PDVSA) or geographical (such as Canadian heavy can more easily capture markets in the Northern Tier markets whereas Maya can compete more effectively on the U.S. Gulf Coast. PHYSICAL LIMITATIONS As shown in Table VI-3, about 3.9 million B/D or 43% of the refinery capacity in PADDs I-III is designed for light sweet. This excludes this capacity from consideration. Another 2.9 million B/D or 32% of the refinery capacity is designed for light sour. Light sour refiners can run some heavy sour but they probably have already heavied up their slate to the extent possible. Therefore, about 75% of the refinery capacity can be excluded as a potential market for Maya or other heavy crude. OWNERSHIP LIMITATIONS PDVSA's equity ownership of more than 900,000 B/D of refining capacity, its substantial import market share among existing third party refineries capable of processing Venezuelan type crude oil, and the discounts that would be needed to increase market share in existing complex refineries or through additions of new capacity effectively limit the possibility of a major shift by PEMEX away from supplying their contracted customers. Should PEMEX attempt such a shift, the resulting competition for the sale of heavy crude oil could result in a downward spiral of retaliatory price discounting, leading to even greater reductions in crude oil prices and total revenues. GEOGRAPHICAL CONSTRAINTS Further market penetration by PEMEX is constrained by logistical advantages of Canadian crude oil in the Midwest region, the various producer/refiner joint venture relationships in the U.S. East and Gulf Coast regions and the somewhat limited sour crude oil processing capacity in the United States. MAJOR FACTORS LIMITING MARKET PENETRATION BY PEMEX REFINERY COMPLEXITY REQUIREMENT The heavy sour crude oil that dominates PEMEX's production requires refineries with relatively high Nelson complexity factors to most efficiently produce higher value refined petroleum products. The Nelson complexity factor is determined by multiplying all reported unit capacities by their complexity factor and dividing by crude oil distillation capacity. A basic topping refinery, which essentially separates crude oil into its boiling point fractions, has a complexity factor of 1.0. A refinery with asphalt capacity, which typically includes a vacuum distillation unit, has a complexity factor of 1.1 to 3.0. A hydroskimming refinery, which is usually a topping refinery with a catalytic reformer to upgrade the naphtha, has a typical complexity of 4 to 6. A cracking refinery which includes either a Fluid Catalytic Cracker (FCCU) or a Hydrocracker to upgrade gas oil into gasoline and distillates typically has a complexity factor range of 5 to 10. A coking refinery has a complexity factor of 7 to 12 and includes a delayed coker, which allows full conversion of the crude oil barrel. Mexico's crude oil is typically processed in coking refineries to realize the full value of the crude oil barrel. Refiners without coking capacity cannot typically process PEMEX's heavy sour crude oil economically, except in specialty asphalt operations. HIGH LEVEL OF SOUR CRUDE OIL CAPACITY UTILIZATION OF EXISTING REFINERIES Due to the high utilization rate of existing heavy oil capacity, PEMEX would find it difficult to divert its heavy crude to other users. Approximately 93% of the 6.9 million barrels per day of sour crude oil capacity in C-41 PADDs I, II, and III was utilized in 1997 (Tables VI-3 and VI-4). Of the underutilized refineries in PADD III in 1997 capable of processing sour crude oil, several of these refineries have long to medium term crude oil supply contracts, including Phillips at Sweeny, Exxon at Baytown, and Clark at Port Arthur. Of the roughly 6.9 million barrels per day of sour crude oil refining capacity in PADDs I, II, and III, PEMEX supplies refineries having a capacity of 4.8 million barrels per day, or 77% of the total capacity. Most is under contract. Typically the contract term is for one year but they are "evergreen" which means they roll-over unless either party terminates the arrangement. STRATEGIC AFFILIATIONS OF COMPETING PRODUCERS Other competing producers are tying up refining capacity that might otherwise be available to process Mexican crude oil. The impact of known producer/refiner affiliations can be seen in the concentration of supply. For example, the total of Middle East crude oil processed by former Saudi Aramco partners Mobil, Chevron, Exxon and affiliate Texaco/Star Enterprise is 973 MBPD, or 68% of Middle Eastern imports of crude oil into the United States. These will further limit PEMEX expansion potential. VENEZUELAN EXTRA HEAVY OIL PROJECTS PDVSA is currently involved in four and negotiating two additional extra heavy oil production and upgrading projects in Venezuela's Orinoco Oil Belt, which will further limit the market for PEMEX's traditional production and imports into the United States to the extent they include PDVSA partner refineries which would otherwise be outlets for traditional PEMEX heavy sour crude oil production. The affected refineries include the Mobil Chalmette refinery, the Conoco Lake Charles refinery, and potentially, the Coastal Corpus Christi and the Exxon refineries. ALTERNATIVE CRUDE SUPPLY If for some reason, PEMEX decided to divert the Maya crude away from the Clark Port Arthur refinery, there are alternative supplies of heavy sour crude that Clark and PACC could likely obtain. Venezuela will be rapidly expanding its heavy crude production as world crude demand grows as Asia recovers. OPEC quota levels will be raised so Venezuela will not have to constrain output. In addition, the heavy oil production (Orinoco) discussed earlier will get back on track and will add to the heavy crude supply. Mexico is expanding its heavy crude production from 1.6 million B/D to 2.3 million B/D by 2015. New customers will need to be found. In addition, an examination of the refineries that purchase Mexican Maya crude indicates that a significant portion is being run in refineries which do not have adequate bottoms upgrading to completely upgrade the bottoms so it is run in a cracking mode rather than in a coking mode. This means that PEMEX could realize a higher value for the Maya if it were sold to a coking operation, like the Upgrade Project. Saudi Arabia is having difficulty in marketing the expanded production from the Neutral Zone. They are pressuring Japan to take more but the Japanese are resisting. Contracts for this crude would not be difficult to obtain.

CRUDE OIL PRICING AND LIGHT/HEAVY DIFFERENTIAL CRUDE OIL PRICING The overall level of crude oil prices is set by the cost of production and the balance between the demand for refined products and the supply of crude oil. If the overall level of prices is high, the supply of crude will tend to increase because of the economic attractiveness of developing new reserves or producing existing reserves at higher rates. At the same time, high prices tend to cause product demand to decrease as relatively less expensive alternative fuels such as coal, natural gas and nuclear energy are substituted for crude oil. The resulting imbalance of supply and demand tends to drive prices down. Similarly, if the price is low, demand is generally stimulated, alternative energy supply development is constrained, and adding new reserves becomes less economical. Ultimately, the low prices cause demand to approach production capacity limits and the resulting competition for supply drives prices back up. The world supply of crude oils is assumed to be consumed in the most economic manner subject to political and structural constraints. The pattern of world crude oil movement establishes the price equalization point for each crude oil and the crude oils it will compete against in that market. The differential values of crude oils are determined by the prices of products in the market, yields of the crude oils in the refineries in which they are used, and processing costs. Purvin & Gertz uses the price of Brent crude oil (light, sweet), FOB Sullom Voe as the basis for forecasting the prices of major crude oils. Brent serves both North American and European markets and competes directly with the Middle Eastern and African crude oils that serve all major markets. The market prices of other crude oils are based on the price of Brent and are developed through an analysis of trading patterns and quality adjustments. Both historical and forecast prices for the various crude oils considered in current and constant dollars, are shown in Tables VII-1 and VII-2, respectively. In an interactive process, product prices for each forecast year are calculated based on expected returns on conversion capacity (which are tied to excesses and shortages of capacity), which is an element of the base crude forecast. Crude prices are then determined as a function of the expected relative yield of a stream of crude oil processed using the type of refinery configuration that has been determined to be the price-setting mechanism in a given market, such as vacuum gas oil cracking in the U.S. Gulf Coast. Using the product price forecast and the relative yields to Brent (or another marker crude), the relative prices of the various crudes can be calculated. The price level of light products relative to heavy products will directionally impact the relative value of light and heavy crudes and the light/heavy differential. Heavy crudes, when run in a cracking mode, will produce more residual fuel oil than light crudes. If the differential for light products versus heavy products is wide, the heavy crude value will be lowered relative to a light crude and the differential will be wide. The reverse is also true, producing narrow differentials. LIGHT/HEAVY DIFFERENTIAL For the purposes of this study and the Upgrade Project, the light/heavy differential has been defined as the difference between the respective spot prices of WTI at Cushing for the light crude and Maya FOB Mexico for the heavy crude. FACTORS THAT AFFECT THE LIGHT/HEAVY DIFFERENTIAL The light/heavy differential is the result of a complex balance of a number of factors, such as: 1. Demand for light products: The overall demand for light products, such as gasoline and distillates, determines the total amount of crude oil to be processed, as well as the amount of heavy feedstock available to be converted into light products or burned as fuel. C-50 2. Demand for heavy products relative to demand for light products: As the relative proportion of light products in the overall demand mix increases, more of the heavy portion of each crude barrel must undergo conversion into lighter products in order to satisfy light product demand. The reverse situation can occur as well. 3. Supply of heavy crude: As the quality of the crude oil produced becomes heavier, relatively more conversion capacity is required to process it and meet the requirements of the market, assuming light product demand remains stable. 4. Conversion Capacity heavy feedstock to be upgraded and the corresponding need for conversion capacity. The amount of conversion capacity existing and being built determines the extent to which refiners can upgrade available heavy feedstock into light products. The balance between the demand for upgraded heavy feedstock and available conversion capacity affects the light/heavy differential. RECENT TRENDS IN THE CONVERSION CAPACITY SUPPLY/DEMAND BALANCE In the late 1980s, the balance between conversion capacity and heavy feedstock was tight, with little or no excess capacity. As a result, returns on investment to refiners were sufficient to motivate new investments in capacity. By the early 1990s, the rate of addition of conversion capacity considerably exceeded the needed level. Many producers added this capacity with the intention of processing heavy crude into low sulfur diesel and reformulated gasoline. Many refiners found the most economic way of accomplishing this was to combine various refinery modifications made in response to regulatory changes with expansions of conversion capacity. Since conversion capacity is generally the most profitable increment of refining, many refiners believed that increasing it was the most effective way to maximize returns on product quality improvement investments. However, because so many refiners recognized the potential benefit of increasing conversion capacity, an overbuilding of such capacity resulted. The overabundance of conversion capacity drove up demand for heavy feedstock and resulted in a narrowing of the light/heavy differential through 1995. A recovery in the light/heavy differential occurred in 1996 and 1997. While this recovery was due in part to temporary refinery operating problems at several major refinery units, which decreased the availability of conversion capacity, this recovery was primarily driven by the rising output of heavy crudes in the Western Hemisphere. This increasing production of heavy crude resulted in severe price competition and residual fuel oil oversupply. The spreads reached a peak late in 1997 and early 1998 due to these factors. C-51 In April 1998, the trends began to reverse and the light/heavy differential began to narrow. This reversal was brought about by the confluence of a number of factors. These included the effects of the Asian crisis, which reduced demand for refined products and opened up conversion capacity worldwide. In addition, low oil prices and high natural gas prices in the U.S. caused demand for residual fuel to increase rather dramatically. At the same time, export demand for residual fuel increased sharply due to El Nino related hydropower shortages in Mexico. [GRAPHIC OF FIGURE V-11-1-WORLD CONVERSION CAPACITY CHANGES] Although the rate of increase in conversion capacity fell sharply after 1994, several major projects are currently underway. In addition, several conversion projects are linked to supplies of heavy crude from Venezuela and Mexico that we expect to absorb increases in heavy crude production. Figures VII-1 andVII-2 illustrate the addition of conversion capacity both worldwide and in the U.S. Net additions in recent years have been at a rate of 2% in the U.S. and nearly 4% worldwide. [GRAPHIC OF FIGURE V-11-2-U.S. CONVERSION CAPACITY CHANGES] C-52 RECENT TRENDS IN THE LIGHT/HEAVY DIFFERENTIAL The recent heavy crude production cuts by Venezuela and Canada are causing the light/heavy differential to narrow currently. At the same time, new conversion capacity is being brought on and is absorbing any excess heavy feedstock, thereby strengthening heavy feedstock prices and further narrowing the differential. In addition, high natural gas prices coupled with low residual fuel oil prices are encouraging the burning of resid, thereby squeezing the heavy feedstock balance and narrowing the light/heavy differential even further. Even so, the differential averaged about $5.00 over the past six months. Domestic supply constraints in 1998 increased the price of WTI above the level which would otherwise be expected given the global supply-demand balance. These constraints are in the process of being reversed, and we expect this to reduce the price of WTI. Because these supply constraints did not have a significant impact on the Gulf Coast price of Maya, Purvin & Gertz expects the light/heavy differential to contract as WTI prices decline relative to Maya. Over the short term, the absolute price of WTI is likely to remain in the $15 to $20 per barrel range. Low demand for petroleum caused by the continuation of the Asian financial crisis will cause Venezuela and other OPEC producers to constrain production in the short term. Short term production will be further constrained under the terms of the recent OPEC agreement. Mexico has agreed to constrain exports as well. These factors will tend to keep the light/heavy differential around $5.00 in the short term (i.e. through 2000). VOLATILITY OF THE LIGHT/HEAVY DIFFERENTIAL The changing balances between the key factors discussed above historically have caused a considerable amount of volatility in the light/heavy differential (Figure VII-3). [GRAPHIC OF FIGURE VII-3-WTI CUSHING minus MAYA FOB] C-53 Month to month variations can be expected to continue in the future since both end-product and crude oil prices fluctuate daily due to both short-term speculative activity and fundamental changes in the key drivers over a longer period of time. Some of this volatility is smoothed out when six month moving average data is used (Figure VII-4). For the time period from January 1988 to March 1999, the six month period moving average of the light/heavy differential ranged from a high of $8.90 to a low of $3.76 with an average of $5.83. [GRAPHIC OF FIGURE VII-4-WTI CUSHING minus MAYA FOB MEXICO (6 MONTH MOVING AVERAGE)] As a result of the Gulf War, the differential increased sharply in the 1st quarter of 1990. This increase occurred as crude prices escalated rapidly as both production and conversion capacity in Iraq and Kuwait were lost. Other crude producers increased output of heavy crude to compensate. Refineries also increased runs to compensate for the perceived product shortage. The result was that residual fuel oil production increased as more heavy crude was run in lower conversion operations which were not capable of fully upgrading the heavy feedstock. As the balance was restored the light/heavy differential came off these highs. C-54 LIGHT/HEAVY DIFFERENTIAL FORECAST We believe that after 2000, the light/heavy differential will widen (Figure VII-5) as the key drivers are projected to result in a wider differential: [GRAPHIC OF FIGURE VII-5-WTI CUSHING minus MAYA FOB MEXICO] 1. Demand for light products will increase rapidly (particularly in Asia) as the world economy improves, necessitating more crude processing. 2. Crude prices will increase (Tables VII-1 and VII-2) as demand for crude runs increases due to supply/demand balance tightening. 3. Crude production will increase (particularly heavy crude) as demand for crude increases and higher prices encourage the development of existing and new fields. 4. Venezuela, Mexico and Canada will expedite heavy oil production once OPEC production restrictions are lifted. Typically, producers respond to production limitations by curtailing production of heavy crude disproportionately to production of light crude, primarily because producing heavy crude is less profitable on a per-barrel basis. Assuming producers respond to the most recent OPEC cutbacks in this manner, heavy oil production may decrease in the short term, but will increase sharply once the production and export restrictions are lifted. Thus, there will be an abundant supply of heavy crude oil for the duration of the Upgrade Project. 5. The combination of increased light product demand and increased heavy crude production will increase demand for conversion hardware faster than new conversion capacity can be added, due largely to delays in building projects. Therefore, refiners will be forced to process heavy crude oil in refineries that are incapable of fully upgrading heavy feedstock. As a result, excess residual fuel oil will be produced until sufficient conversion capacity is added to reduce the overhang of heavy feedstock from the market. The market should reach equilibrium in approximately 2005, with the light/heavy differential stabilizing at nearly $6 per barrel in real terms from this point forward, with short term fluctuations around this level. USGC REFINERY MARGINS Refinery margins were very low for most of the 1980s because of excess capacity resulting from the prior decline in product demand in the early 1980s. By the later 1980s, capacity had been largely rationalized, demand was once again growing and margins strengthened considerably. The industry did not enjoy a very long respite, as a wave of refining investment resulted in a return of over capacity. C-55 In the following section, the marginal refinery for the USGC is developed and margins as a function of complexity and crude type are projected. These margins and grade differentials between products are used to forecast a consistent set of product prices. Forecasts for the benchmark margins along with the forecast of USGC product prices are given in Tables VII-3 through VII-8. DRIVERS OF REFINERY PROFITABILITY Refinery profitability is driven primarily by supply/demand pressures. Capacity utilization, both in overall refinery capacity as well as conversion capacity, is the most direct measure of supply/demand pressures. Of course, in the short term, excessive capacity utilization can create excess supply and put downward pressures on margins. However, if an industry needs to operate at near capacity to meet demand, margins generally are good. Rather than using domestic capacity to produce the needed demand, imports from foreign sources can also meet these requirements. Availability of imports depends on the worldwide balance and the amount of spare capacity in areas such as Europe and the Caribbean, which can ship products to the U.S. Over the longer term, capital expenditures measure the amount of new capacity coming onstream, which can influence capacity utilization. On the other hand, required capital expenditures in a low margin environment can force shutdowns of facilities, further tightening the supply/demand balance. Conversely, if margins are strong, capital expenditures can lead to overbuilding of capacity. Commodity markets are a wild card in the drivers of refinery profitability. At the minimum, these commodity markets greatly enhance the sensitivity of margin to small supply/demand imbalances and create drastic short term cyclic behavior. On a broader basis, commodity markets greatly increase the number of participants in the market and the increased competition tends to drive down margins, even when the supply/demand balance is only marginally long. Each of these drivers will be discussed subsequently. [GRAPHIC OF FIGURE VII-6-RELATIVE MARGIN INDICATOR FOR 29 USGC REFINERIES (PPI)] C-56 [GRAPHIC OF FIGURE VII-7-USGC LLS CRACKING MARGINS AFTER VARIABLE COSTS] [GRAPHIC OF FIGURE V-II-8 USGC LLS CRACKING VARIABLE COST MARGIN] C-57 Capacity Utilization Capacity utilization is an important driver of margins because it is a measure of supply/demand pressure. High utilization rates make it difficult to respond quickly to unexpected market imbalances and cause prices to be bid up to attract supplies. Capacity utilization is also important in determining the marginal refinery economics serving a region; the higher the utilization rate, the less efficient the marginal supplier. The marginal USGC refinery has continually become more efficient. Production of residual fuel oil by USGC refineries have now fallen to nearly 4% of crude runs. Operating costs have steadily been reduced. Our analysis shows that virtually all USGC refineries have some form of bottoms upgrading, ranging from direct cat cracking of "clean" resids to hydroprocessing and coking. In the late 1980s, the marginal refinery had no bottoms upgrading and long term margins needed to support full cost economics of the cracking refinery. The processing power index (PPI) is our way of measuring refinery complexity. Unlike other measures of complexity, it is designed to measure margin generating capability, rather than replacement cost. We have found that refinery margins depend strongly on the processing power of the refinery, that is, its ability to use the lowest cost raw material and make the highest value possible products. The PPI is based on the scale of the operation, conversion intensity and hydrogen intensity. We maintain models of seven different refinery configurations on the Gulf Coast of varying degrees of complexity and type of crude processed. By rating each of these model refineries according to scale, conversion intensity and hydrogen intensity, we have been able to develop weighting factors on how each of these contributes to margin. As shown in Figure VII-6 all but one USGC refinery (excluding small specialty operations) are significantly better than the LLS cracking refinery (a cracking refinery with no vacuum bottoms upgrading processing Light Louisiana Sweet crude oil). This represents a significant portion of the U.S. supply and, thus, most members of the group must survive in order to meet demand requirements. This group is shown to have margins about $0.50/bbl. better than the LLS cracking refinery. The relative position of the Clark Port Arthur refinery is shown in Figure VII-6 before and after the coker Upgrade Project. It can be seen that the coker Upgrade Project will move Clark's refinery at Port Arthur from below the middle of the group to near the top. Annual average margins after variable costs for the LLS cracking refinery are shown in Figure VII-7 During the late 1980s, this refinery had a margin above variable cost of well over the fixed cost level of about $1.20 per barrel. Thus, margins were sufficient to support the full cost operation of this type of facility, including sufficient funds to meet needed capital expenditures. Following the building boom in conversion capacity in the early 1990s, the margin for this operation fell below the fixed cost level. However, the margin on average was sufficient to justify incremental processing. We estimate that a margin above variable cost of about $0.50 a barrel is needed to justify incremental processing. This level is sufficient to cover timing risks and other market uncertainties so that the refiner has an incentive to process the marginal barrel. Going forward, we believe that this marginal LLS refining operation will continue to be the marginal source of product on the U.S. Gulf Coast. In order to understand the basis for our forecast, it is necessary to look beyond the annual averages. Commodity pricing of crude oil and products generates high frequency cycles which must be analyzed to project the evolution of margins. Commodity Driven Cycles The impact of commodity markets on margins is difficult to analyze and is the subject of controversy. The financial community, which benefits from large numbers of paper transactions, portrays the commodity markets as merely a mirror reflecting the industry. On the other hand, many industry participants believe that the markets are not merely a reflection, but are creating the image. The demand for paper instruments has an C-58 impact on the supply/demand balance just as a demand for physical barrels, although in the long term, the physical balance must prevail. Commodity markets greatly increase the number of participants since no physical position or assets are required, only a credit line. For refining, the problem is further exacerbated by the fact that most of the activity is on crude oil rather than on products. The concentration of activity in crude oil results from its fundability and a smaller risk compared to refined products. Likewise, producers have a much greater need for hedging instruments to lock in production profits and loan repayments than do consumers of refined products. Thus, a large demand for crude oil hedging instruments is met by speculators, commodity funds, etc. The result is that the crude oil market can often go in a different direction from product markets depending on the supply/demand for hedging instruments as opposed to the supply/demand for physical crude oil. Commodity markets have made it impossible to have market leadership to provide discipline in downward cycles to prevent margins from plunging to levels that shut in marginal production. The international nature of the market further aggravates the problem by causing imbalances in any part of the world to quickly spread to all markets. The result is that prices are extremely sensitive to small changes in the supply/demand balance. The sensitivity of margins is shown in Figure VII-8. The volatility and cyclic behavior is apparent in this chart of monthly averages. Daily averages would show even greater volatility. Cycles in refining are likely to continue to have very high frequency because of the overall slow growth in demand. That is, imbalances can quickly be met and, if necessary, modest capital expenditures can add capacity commensurate with the rate of growth in demand. By contrast, the chemical industry which is growing at a 4% or 5% rate, shows longer term cyclic behaviors and capacity shortages may take several years to work off. Thus, chemicals can enjoy very strong earnings during their upward cycles for several years. The average margin only tells part of the story. The peak level margins form one set of data points while the bottom level another. In addition, a number of points are intermediate. Margin Forecast for LLS Cracker The margin chart (Figure VII-8) can be idealized somewhat as corresponding to three basic zones of operation. In the "boom" zone, capacity is running full out, margins are sufficient to attract imports, and the profit for running incremental crude oil covers fully allocated costs. This level of profitability would produce very satisfactory returns for the refining industry if it could be sustained. The "bust" cycle occurs when considerable excess product is available on the market. In this part of the cycle, runs must be cut to bring supply/demand back into balance. At this level, a marginal loss occurs on incremental runs. The marginal part of the cycle has the highest frequency of occurrence and is the basis of our theory of incremental supply. At this level of margin, it is profitable to run incremental crude oil at a marginal profit of about 50c per barrel. At this level, the risk of holding inventory can be compensated and an incentive occurs to produce marginal product. As the supply/demand balance tightens for the reasons discussed previously, we believe that the frequency of the cycles will change, although their basic character will not. We anticipate more and longer boom cycles and fewer of the bust cycles. As capacity tightens, turnarounds, unexpected cold weather, etc. will have a bigger impact and a greater chance of forcing up margins. From November 1997 until December 1998 the monthly averages have been above the "bust" category and there have been a number of data points in the "boom" category. However, margins weakened in first half of 1999. In the near term, some downward pressure may result from the full startup of the Trans-American refinery. After that, we forecast an average trend line at approximately full cost break-even economics. Refinery Margins In Table VII-3 through VII-6, historical and forecast margins and incremental returns are presented for several USGC refinery configurations in current and constant 1999 dollars. Capital intensive heavy crude C-59 operations show the greatest return. These margins are based on producing fuel products only. Many refineries also produce lubes, chemicals, and specialty products. These operations can have a significant impact on profitability in addition to the basic fuel operations. USGC PRODUCT PRICES The USGC product price forecast is shown in Tables VII-7 and VII-8 in current and constant 1999 dollars, respectively. The prices are spot pipeline lows for light products and waterborne lows for residual fuel oil. These prices are developed through an iterative procedure from the forecast margins discussed above and the product price relationships discussed below. GASOLINE The relationship among the gasoline grades and the pricing of oxygenated and reformulated gasolines through the forecast are important to the economics of capacity additions and modifications necessary for the industry to be able to supply these changing fuels. The subsections below describe the basis, methodology and results for forecasting the prices of the various gasoline grades. Conventional Grades Purvin & Gertz expects conventional gasolines to remain a large part of the pool throughout the forecast. However, the relationships among the conventional grades have changed as reformulated fuels were introduced into the pool, since the value of octane has been modified by the addition of substantial quantities of MTBE and other oxygenates. The pricing of different grades of conventional gasoline is a function of the value of octane. The value of octane is determined by the cost of manufacture. Our calculations are based on incremental reforming costs. Reforming operations are the major source of incremental octane in the U.S. refining industry. Higher octane gasolines are more costly to produce due to higher severity in the reformer. Higher severity results in lower yields of gasoline, higher proportions of less valuable by-products and additional operating costs. The relationship is non-linear and must be determined through calculations of costs at various levels of severity. The results of this analysis are summarized in the following table along with the actual market differentials experienced. CONVENTIONAL GASOLINE OCTANE COSTS AND MAREKT DIFFERENTIALS (Forecast in 1999 Dollars per Barrel) 1987 1990 1991 1992 1993 1993 1995 1996 1997 2000 2005 2010 2015 ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- Low Octane Cost......... 0.20 0.33 0.29 0.23 0.18 0.18 0.20 0.20 0.19 0.13 0.19 0.20 0.19 Market....... 0.21 0.39 0.31 0.27 0.24 0.25 0.24 0.24 0.24 0.17 0.23 0.23 0.23 High Octane Cost......... 0.29 0.47 0.42 0.33 0.26 0.28 0.28 0.28 0.27 0.19 0.27 0.27 0.27 Market....... 0.35 0.49 0.31 0.34 0.28 0.37 0.33 0.28 0.27 0.25 0.30 0.30 0.30 In the table above, low octane represents the cost per octane barrel when producing regular gasoline, while high octane represents the costs when producing premium gasoline. Cost is based on variable costs of operation and by-product yields on the USGC. The low octane market value is that implied from USGC spot market differentials between 70 (R+M)/2 natural gasoline and unleaded regular. The high octane market value is based on the differential between unleaded regular and premium gasoline. Historically, there was often a small market premium above cost. We expect octane values to continue to reflect a small market add-on versus our estimated cost of manufacture. The premium should, however, remain modest as all octane costs have been reduced with the introduction of reformulated fuels. C-60 With the introduction of mandated reformulated gasoline, the basis of all octane values has shifted due to the net effects of addition of MTBE and modified processing. Addition of MTBE to even a portion of the gasoline pool results in reduced severity of operations to meet total octane requirements. This applies to the conventional grade gasoline that is still manufactured and sold in non-reformulated areas as well as to the reformulated grades. Reformulated Gasoline The cost of making reformulated gasoline will vary considerably from refinery to refinery, but in order to index the spot market spreads, the reformulated cost differential above conventional gasoline was calculated for our base sour crude cracking refinery. A summary of the results is shown in the table below. REFORMULATED/CONVENTIONAL GASOLINE COST DIFFERENTIALS (Forecast in Constant 1999 Cents/Gallon) Phase I (1998) Phase II (2000) -------------- --------------- Variable Operating Costs................. 3.60 5.07 Fixed Operating Costs.................... 2.98 3.72 Oxygenate/Yield Credit................... (2.25) (6.17) Capital Recovery......................... (1.81) 1.49 ----- ----- Total.................................. 2.53 4.12 Our process simulations indicated that it is not very difficult to produce Phase I reformulated gasoline while at the same time making low sulfur diesel. Refinery operations needed to be modified only moderately, and the major investment required and higher operating costs are associated with the requirement to add oxygenates to regular gasoline. Most refineries have added MTBE plants based on refinery isobutylenes and adequate supplies of other MTBE are available for purchase. The price premiums for Phase I gasoline over conventional gasoline are calculated to be in the 2.0-2.5c per gallon range under conditions of normal MTBE prices. In 1995, MTBE prices were inflated early in the year by high methanol costs, resulting in reformulated fuel premiums peaking in the 6-7c gallon range. This resulted in an average annual premium on reformulated gasoline in the 3.5c range for that year. On the other hand, the average spread in 1997 and 1998 was about 2.5c per gallon and similar levels are projected until Phase II product is introduced. Purvin & Gertz expects Phase II reformulated fuels to show premiums of about 4c per gallon versus conventional gasoline. Some additional refinery investment will be required to meet sulfur, olefins, aromatics, and distillation restrictions. Many refiners have already added processing which will enable them to produce Phase I complex model and Phase II reformulated fuels. However, we believe pricing should reflect some capital recovery for the additional industry requirements. DISTILLATE FUELS Standard Distillate In this discussion we will refer to typical specification, heating oil/diesel fuel as "standard distillate," while the 0.05% sulfur diesel fuel introduced in 1993 will be referred to as "low sulfur" diesel. Distillate fuel oil prices are projected based on a relationship versus unleaded regular standard gasoline. Distillate price differentials are somewhat more difficult to calculate on a strict refining economics basis due to the seasonal nature of price trends. Typically, the summer differentials will rise to a level that more than supports the maximized conversion of this material to gasoline through revised cutpoints for FCCU charge. At maximum utilization of cracking capacity, the differential often rises above balanced levels. Our forecasts are based on a summertime (second and third quarter) distillate discount averaging in the 5c per gallon range, though peaks well over this level are typical. C-61 Wintertime balances can be erratic and the typical premium on distillate during the winter season is both a function of the distillate balance, the weather conditions and the relative strength or weakness of the gasoline balance. Under typical conditions, we estimate the wintertime premium (first and last quarters of the year) to be near zero. Often the strongest distillate period is just prior to the winter as inventories are being added to meet peak winter requirements. The combination of the expected averages yields a long term forecast for a 2.5c discount for standard distillates relative to conventional gasoline on a yearly average basis. From 1992-1996 the average differentials were narrower than the expected longer term trend. This has resulted primarily from overcapacity to convert distillates and a weak gasoline market due to oversupply. In 1997, the spread widened out to over 4.5c as a result of a mild winter and strong gasoline demand, late in the summer season (July to September). Product demand growth will absorb the extra capacity and distillate discounts should return to more normal levels in 1998 and in the future. Low Sulfur Diesel Low sulfur diesel fuel was introduced in the fourth quarter of 1993 to meet the new EPA requirements for on-highway fuel. This material must have a sulfur content less than or equal to 0.05%. Pricing of this new fuel can be volatile on a seasonal basis. Its pricing will be a function of operating costs and regional supply/demand balances. Based on the production data available, U.S. refineries are capable of producing more than enough low sulfur diesel to meet the market's requirements. The premium for this fuel has, therefore, has remained relatively low, reflecting only variable costs with no fixed cost or capital recovery. Based on simulations of refinery operations in each PADD, it appears that more than enough low sulfur diesel can be produced than is required by regulation. Therefore, we do not expect refiners to have the opportunity to earn a return on capital. The price differential should remain close to variable cost and this expectation has been confirmed over the years since introduction. Our cost calculations indicate that the low cost supply source should not be able to recover much more than 1.5c per gallon for low sulfur diesel relative to the baseline standard fuel. We are assuming that in the long term, supply capabilities will exceed demand, and this variable cost differential is used as the long term equilibrium price differential. RESIDUAL FUEL OIL We do not envision shortages of low sulfur crude oils in the international market, and expect that low sulfur fuel oil will continue to be made from low sulfur crude bottoms and indirect desulfurization/blending. We do not expect the demand for low sulfur residual fuel oil to be high enough to require desulfurizing sour vacuum bottoms to produce low sulfur fuel oil in most markets. Consequently, the differential will be set by the alternative of additional processing to produce light products rather than fuel oil. This processing requires significant desulfurization investment and higher operating costs for sour residuals versus low sulfur residuals. Thus, the differential between high and low sulfur fuel oil closely follows trends in conversion returns. When conversion capacity is slack and returns are low, refiners will maximize income by preferentially processing the lower cost high sulfur feedstocks, reducing the sweet-sour differential. When capacity is tight, however, processing low sulfur material can effectively increase capacity due to its high yields, and so the differential between high and low sulfur residual widens. The forecast differential is based on continuation of the observed relationship with the conversion return.

Section 145 of the General Corporation Law of the State of Delaware (the "Delaware Law") authorizes the registrants to indemnify their officers and directors under certain circumstances and subject to certain conditions and limitations as stated therein, against all expenses and liabilities incurred by or imposed upon them as a result of actions, suits and proceedings, civil or criminal, brought against them as such officers and directors if they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the registrants and, with respect to any criminal action or proceeding, had no reasonable cause to believe their conduct was unlawful. Reference is hereby made to Article 11 of the Certificate of Incorporation of Port Arthur Finance and Article 10 of the Amended and Restated Certificates of Incorporation of Sabine River and Neches River, copies of which are filed as Exhibits 3.01(a), 3.01(b) and 3.01(c), respectively, each of which provides for indemnification of officers and directors to the fullest extent permitted by Delaware Law. Reference is hereby made to Section 7.1 of the By Laws of Port Arthur Finance and Section 7.1 of the Amended and Restated By Laws of each of Sabine River and Neches River, copies of which are filed as Exhibits 3.02(a), 3.02(b) and 3.02(c), respectively, each of which provides for indemnification of directors or officers in derivative and non derivative actions in the circumstances provided in such Section 7.1. Section 7.2 of the By Laws of Port Arthur Finance and Section 7.2 of the Amended and Restated By Laws of each of Sabine River and Neches River authorize each such company to purchase and maintain insurance on behalf of any director, officer, employee or agent of such company against any liability asserted against or incurred by them in such capacity or arising out of their status as such, whether or not such company would have the power to indemnify such person against such liability.

Reference is made to Section 7 of the Purchase Agreement, copy of which is filed as Exhibit 1.01 for information concerning indemnification arrangements among the registrants and the initial purchasers of the outstanding notes.

II-3 (b) Financial Statement Schedules Item 22. Undertakings (a) The undersigned registrants hereby undertake to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective. (b) Insofar as indemnification for liabilities arising under Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrants pursuant to the foregoing provisions, or otherwise, the registrants have been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the applicable registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. (c) The undersigned registrants hereby undertake: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i)to include any prospectus required by Section 10(a)(3) of the Securities Act; (ii)to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more that a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and (iii)to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; (2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; and (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
