(b) Tender Offer. This Schedule 14D-9 relates to the tender offer made by the Purchaser, disclosed in a Tender Offer Statement on Schedule TO dated January 8, 2001 (as amended or supplemented from time to time, the "Schedule TO"), to purchase all of the outstanding shares of Common Stock, together with the associated Rights, at a price (the "Offer Price") of $19.00 per Share, net to the seller in cash, without interest, upon the terms and subject to the conditions set forth in the Offer to Purchase, dated January 8, 2001 (as amended or supplemented from time to time, the "Offer to Purchase"), and the related Letter of Transmittal (which, together with any amendments or supplements thereto, collectively constitute the "Offer"), copies of which are filed as Exhibits (a)(1) and (a)(2) hereto, respectively, and incorporated herein by reference. The Offer is being made pursuant to an Agreement and Plan of Merger, dated as of December 22, 2000, among the Company, Marathon and the Purchaser (the "Merger Agreement"), which provides for (i) the making of the Offer by the Purchaser, subject to the conditions set forth in the Offer and to the conditions and upon the terms of the Merger Agreement and (ii) the subsequent merger of the Purchaser with and into the Company (the "Merger"), at which time the separate corporate existence of the Purchaser shall cease and the Company shall continue as the surviving corporation (the "Surviving Corporation"). In the Merger, each Share, except for Shares owned by the Company, the Purchaser, Marathon and any stockholder properly exercising appraisal rights, if available, outstanding at the Effective Time (as defined in the Merger Agreement) will, by virtue of the Merger and without any action by the holder thereof, be converted into the right to receive, without interest, an amount in cash equal to the price per Share paid in the Offer (the "Merger Consideration"). The Merger Agreement, a copy of which is filed as Exhibit (e)(1) hereto, is summarized in Section 12 of the Offer to Purchase and incorporated herein by reference. As set forth in the Schedule TO, the principal executive offices of the Purchaser and Marathon are located at 5555 San Felipe, Houston, Texas 77056 and the principal executive offices of USX are located at 600 Grant Street, Pittsburgh, Pennsylvania 15219-4776. ITEM 3. PAST CONTACTS, TRANSACTIONS, NEGOTIATIONS AND AGREEMENTS. Except as set forth in response to this Item 3 or in Annex A attached hereto or as incorporated by reference herein, to the knowledge of the Company, there are no material agreements, arrangements, or understandings and no actual or potential conflicts of interest between the Company or its affiliates, on the one 1 3 hand, and (1) the Company's executive officers, directors or affiliates or (2) the Purchaser, Marathon, USX or any of their respective executive officers, directors or affiliates, on the other hand. A summary of the material provisions of the Merger Agreement is included in Section 12 of the Offer to Purchase, which is incorporated herein by reference. The summary of the Merger Agreement in the Offer to Purchase is qualified in its entirety by reference to the Merger Agreement. Certain contracts, arrangements, or understandings between the Company or its affiliates and certain of the Company's directors, executive officers and affiliates are described in the Information Statement of the Company attached to this Schedule 14D-9 as Annex A (the "Information Statement"). The Information Statement is being furnished to the Company's stockholders pursuant to Section 14(f) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and Rule 14f-1 issued under the Exchange Act in connection with the Purchaser's right (after acceptance for payment of, and payment by Purchaser for, any Shares pursuant to the Offer) to designate persons to the Board of Directors of the Company (the "Board") other than at a meeting of the stockholders of the Company. The Information Statement is incorporated herein by reference. The Company's executive officers are parties to employment agreements, as well as "parachute" tax agreements, which may provide them with compensation as a result of the consummation of the Merger. Each of these agreements is described in more detail in the Information Statement. Under the terms of the Company's 1998 Stock Option and Incentive Plan (the "Plan"), all outstanding stock options will vest as a result of the transactions contemplated by the Merger Agreement. Pursuant to the Merger Agreement, the Board (or the Compensation Committee of the Board) will take or cause to be taken such actions as are required to provide that each stock option outstanding immediately prior to the acceptance for payment of Shares pursuant to the Offer will be canceled, with the holder thereof becoming entitled to receive the amount of cash in respect of such stock options as provided in the Plan upon a change in control. The Plan provides that the option holder will receive the Black Scholes value of the options upon the change in control. As a condition to entering into the Merger Agreement, Marathon required that holders of approximately 90% of the outstanding stock options, including all directors and executive officers, agree that each stock option held by such holder will be canceled, with such holder becoming entitled to receive an amount of cash in respect of such stock option equal to the product of (A) the excess, if any, of (x) the Merger Consideration over (y) the exercise price per share subject to such stock option and (B) the number of shares subject to such stock option immediately prior to its cancellation. Information regarding options held by the Company's directors and executive officers is set forth in the Information Statement. The Merger Agreement also provides that Marathon will cause the Surviving Corporation to indemnify, for a period of six years from the Effective Time, each person who is now, or has been at any time, a director or officer of the Company, for claims or losses based on, or arising out of, the fact that such person is or was a director or officer of the Company, in each case, to the full extent that Marathon or the Company is permitted under applicable law to so indemnify. In addition, Marathon has agreed to cause to be maintained for a period of not less than six years after the Effective Time, an insurance and indemnification policy for the benefit of those persons who are covered by the Company's directors' and officers' liability insurance at the Effective Time that provides for coverage of events occurring at or prior to the Effective Time (the "D & O Insurance"). The D & O Insurance will be at least equal to the coverage provided under the Company's current directors' and officers' liability insurance policies, to the extent that such liability insurance can be maintained at an annual cost to Marathon not greater than 150 percent of the premium for the current Company directors' and officers' liability insurance; provided, however, that if such insurance cannot be so maintained at or below such cost, Marathon will maintain as much of such insurance as can be so maintained at a cost equal to 150 percent of the current annual premiums of the Company for such insurance. ITEM 4. THE SOLICITATION OR RECOMMENDATION. (a) Solicitation or Recommendation. At a meeting held on December 22, 2000, the Board unanimously (i) approved the Merger Agreement, the Offer and the Merger, (ii) determined that the Offer and the Merger are advisable and fair to, and in the best interests of, the Company and its stockholders, and (iii) voted 2 4 to recommend that the Company's stockholders accept the Offer and tender their Shares pursuant to the Offer. Accordingly, the Board unanimously recommends that the stockholders of the Company accept the Offer and tender their Shares pursuant to the Offer. Copies of the Company's letter to the stockholders of the Company communicating the Board's recommendation and the joint press release of the Company and Marathon announcing the Merger Agreement and the transactions contemplated thereby are filed as Exhibits (a)(3) and (a)(4) hereto, respectively, and are incorporated herein by reference. (b) Reasons. Background of the Offer. From time to time, the Company has been the subject of informal inquiries regarding a possible acquisition or other business combination transaction. On September 8, 2000, Mr. Douglas E. Brooks, Manager -- Business Development for the Rocky Mountain Region of Marathon, made such an initial inquiry to Mr. Paul M. Rady, Chairman of the Board, President and Chief Executive Officer of the Company. In response to the inquiry, the Company provided representatives of Marathon with various materials containing publicly available information about the Company's operations. On November 8, 2000, Mr. Clarence P. Cazalot, President of Marathon, contacted Mr. Rady to express Marathon's interest in acquiring the Company and to explore business combination options. On November 10, 2000, Mr. Rady and Mr. Glen C. Warren, Jr., Executive Vice President, Chief Financial Officer and Director of the Company, met in Houston, Texas with Mr. Cazalot, Mr. Steven B. Hinchman, Senior Vice President -- Operations of Marathon, and Mr. Richard J. Murphy, Manager -- Mergers and Acquisitions of Marathon, to discuss a potential acquisition transaction. The parties agreed to further explore a possible transaction over the next 30 days. The Company agreed at that time to provide Marathon with information concerning the Company's operations pursuant to the terms of a confidentiality agreement dated as of November 15, 2000. On November 16 and 17, 2000, representatives of Marathon met with members of the Company's senior management team in Denver, Colorado for an initial due diligence session. Throughout the latter half of November and the first half of December 2000, Marathon conducted a due diligence review of the Company and its operations. As a result of the preliminary discussions with Marathon, as well as other informal inquiries that had been received from time to time, the Company determined in late November 2000 to interview several investment banking firms in order to retain a financial advisor, which would assist the Company with any potential transaction with Marathon, as well as any other inquiries that might be received or solicited. On December 8, 2000, Mr. Cazalot discussed with Mr. Rady Marathon's initial valuation of the Company. After receiving this initial indication of interest, the Board held a special meeting on the same day to discuss a potential transaction with Marathon. The Board was advised of the level of Marathon's indication of interest and determined that the initial valuation was not acceptable. However, the Board authorized the officers of the Company to continue discussions with Marathon's representatives. Following this meeting, Company representatives held additional discussions and provided additional due diligence materials to Marathon's representatives. On December 14, 2000, the Company's senior management was advised of a revised indication of interest from Marathon at an increased offer price of $19.00 per Share. At a regularly scheduled meeting of the Board held on the same date, the Board was advised of this revised indication of interest and of the status of the continuing discussions with Marathon. At this meeting, the Board authorized continued discussions with representatives of Marathon, authorized the engagement of Lehman Brothers Inc. ("Lehman Brothers") to act as its financial advisor with respect to the proposed transaction and authorized the appropriate officers of the Company to engage legal counsel. On December 15, 2000, following continued discussions between senior representatives of Marathon and the Company, the representatives of the parties reached a tentative agreement as to the principal economic terms of the transaction, subject to finalizing Marathon's due diligence, negotiation of a definitive agreement and the approval of each party's board of directors. The Company directed its counsel to prepare an initial draft of the Merger Agreement, which was circulated to Marathon and its representatives on December 18, 2000. Lehman Brothers conducted formal due diligence with the Company's senior management in Denver, 3 5 Colorado on December 18, 2000. Between December 18 and 22, 2000, representatives of Marathon conducted a further due diligence review of the Company and its assets and operations. On December 19, 2000, the Board held a special meeting to again discuss the terms of the proposed transaction. Representatives of Lehman Brothers were also present at the meeting and described the role Lehman Brothers would play in connection with the continued discussions with Marathon and the fairness analysis Lehman Brothers would undertake to deliver. Representatives of the Company's counsel were also present and described the legal issues surrounding a proposed transaction, as well as the terms of the transaction contained in the initial draft of the Merger Agreement that had been delivered to Marathon and its legal counsel. The Board directed the appropriate officers of the Company, assisted by Lehman Brothers, as well as Company counsel, to continue negotiations with Marathon and its representatives. Following this meeting, representatives of the Company and Marathon proceeded to negotiate, in detail, the terms of the proposed transaction at meetings and conference calls held December 20, 21 and 22, 2000. On December 22, 2000, the Board held a special meeting to review and discuss with the Company's management and legal and financial advisors the terms of the proposed acquisition and the applicable agreements. At this meeting, Lehman Brothers reviewed with the Board its financial analysis of the consideration payable in the Offer and the Merger and rendered to the Board an oral opinion (confirmed in writing) to the effect that, as of the date of the opinion and based upon and subject to certain matters stated in such opinion, the $19.00 per Share cash consideration to be received in the Offer and the Merger by the Company's stockholders (other than the Company, the Purchaser and Marathon) was fair, from a financial point of view, to such holders. Also at this meeting, the Company's counsel gave an update with respect to various legal aspects of the transaction. At the conclusion of this meeting, the Board unanimously approved the Offer, the Merger and the Merger Agreement, determined that the Offer, the Merger and the Merger Agreement are advisable and fair to and in the best interests of the Company's stockholders, and recommended that the stockholders accept the Offer and tender their Shares pursuant thereto. The Merger Agreement was thereafter finalized and executed after the closing of trading on December 22, 2000, and a joint press release announcing the proposed Offer and the Merger was issued by the Company and Marathon. On January 8, 2001, the Purchaser commenced the Offer. For additional information regarding the background of the Offer, please read Section 11 of the Offer to Purchase, which is incorporated herein by reference. Reasons. In making the determinations and recommendations set forth in subparagraph (a) above, the Board considered a number of factors, including, without limitation, the following: - the Board's knowledge of the Company's business, operations, prospects, projected financial performance and competitive position and current trends in the natural gas industry, including production of coal bed methane gas; - the financial and other terms and conditions of the Offer and the Merger Agreement and the fact that they were the product of arm's-length negotiations between the parties; - the fact that the $19.00 per Share price to be received by the Company's stockholders in the Offer and the Merger represents a significant premium over the historical trading prices for the Company's Common Stock since it began trading in July 1998, including a 30% premium over the closing market price of $14.625 per share on December 21, 2000, the last full trading day prior to the Board's approval of the Merger Agreement and a 40% premium over the average closing market price of $13.5375 per share for the 20 trading days prior to the Board's approval of the Merger Agreement; - the fact that the Offer and the Merger provide for a prompt cash tender offer for all of the Shares to be followed by the Merger for the same consideration, thereby enabling the Company's stockholders, to obtain promptly the benefits of the transaction in exchange for their Shares; 4 6 - the financial presentation of Lehman Brothers, including its opinion as to the fairness, from a financial point of view and as of the date of the opinion, of the $19.00 per Share cash consideration to be received in the Offer and the Merger by the Company's stockholders (other than the Company, the Purchaser and Marathon). The full text of Lehman Brothers' written opinion, dated December 22, 2000, which sets forth the assumptions made, matters considered and limitations on the review undertaken by Lehman Brothers, is attached hereto as Annex B and is incorporated herein by reference; - the fact that the Offer and the Merger were not expressly conditioned on the availability of financing, which, combined with the experience, reputation and financial condition of Marathon, increased the likelihood that the proposed Offer and Merger would be consummated; - the terms of the Merger Agreement, including the parties' representations, warranties and covenants and the conditions to their respective obligations; - the interests of the Company's directors and executive officers in the proposed transaction as set forth in Item 3 above; and - the fact that the Company may terminate the Merger Agreement in order to approve a tender offer for the Shares or other proposed business combination by a third party on terms more favorable to the Company's stockholders than the Offer and the Merger, upon the payment to Marathon of a $15 million termination fee. The Board did not assign relative weights to the above factors or determine that any factor was of particular importance. Rather, the Board viewed its position and recommendations as being based on the totality of the information presented to and considered by it. In addition, it is possible that different members of the Board assigned different weights to the various factors described above. (c) Intent to Tender. To the Company's knowledge after reasonable inquiry, the Company's executive officers, directors and affiliates currently intend to tender all Shares held of record or beneficially by them pursuant to the Offer or to vote in favor of the Merger. The foregoing does not include Common Stock over which, or with respect to which, any such executive officer, director or affiliate acts in a fiduciary or representative capacity or is subject to the instructions of a third party with respect to such tender. ITEM 5. PERSON/ASSETS, RETAINED, EMPLOYED, COMPENSATED OR USED. The Company has retained Lehman Brothers to act as its exclusive financial advisor in connection with the Offer and the Merger. Pursuant to the terms of Lehman Brothers' engagement, the Company has agreed to pay Lehman Brothers for its services, upon consummation of the Offer and the Merger, an aggregate fee equal to a percentage of the total consideration, including liabilities assumed, payable in the Offer and the Merger. The aggregate fee payable to Lehman Brothers is currently estimated to be approximately $3 million. The Company has also agreed to reimburse Lehman Brothers for reasonable travel and other out-of-pocket expenses, including reasonable fees and expenses of its legal counsel, and to indemnify Lehman Brothers and related parties against certain liabilities, including liabilities under the federal securities laws, arising out of Lehman Brothers' engagement. In the ordinary course of business, Lehman Brothers and its affiliates may actively trade or hold the securities of the Company and affiliates of Marathon for their own account or for the account of customers and, accordingly, may at any time hold a long or short position in such securities. Neither the Company nor any person acting on its behalf has employed, retained or compensated any other person to make solicitations or recommendations to stockholders on its behalf concerning the Offer or the Merger. ITEM 6. INTEREST IN SECURITIES OF THE SUBJECT COMPANY. During the past 60 days, neither the Company nor any subsidiary of the Company nor, to the best of the Company's knowledge, any executive officer, director, or affiliate of the Company has effected a transaction in shares of Common Stock. 5 7 ITEM 7. PURPOSES OF THE TRANSACTION AND PLANS OR PROPOSALS. Other than as set forth in this Schedule 14D-9, no negotiation is being undertaken or is underway by the Company in response to the Offer that relates to: - a tender offer or other acquisition of the Company's securities by the Company, any subsidiary of the Company or any other person; - an extraordinary transaction, such as a merger, reorganization or liquidation, involving the Company or any subsidiary of the Company; - a purchase, sale or transfer of a material amount of assets of the Company or any subsidiary of the Company; or - any material change in the present dividend rate or policy, or indebtedness or capitalization of the Company. Except as described above or in Item 3 of this Schedule 14D-9, there are no transactions, board resolutions, agreements in principle or signed contracts in response to the Offer that relate to or would result in one or more of the matters referred to in this Item 7. ITEM 8. ADDITIONAL INFORMATION. (a) Delaware General Corporation Law. Under the Delaware General Corporation Law (the "DGCL"), if the Purchaser or any other subsidiary of Marathon acquires, pursuant to the Offer or otherwise, at least 90% of the outstanding Shares, the Purchaser will be able to effect the Merger after consummation of the Offer without a vote of the Company's stockholders. However, if the Purchaser does not acquire at least 90% of the outstanding Shares, a vote of the Company's stockholders is required under the DGCL, and a longer period of time will be required to effect the Merger.

STOCK OPTION PLAN Under the Company's 1998 Stock Option and Incentive Plan (as amended, the "Plan"), 5,500,000 shares of Common Stock are reserved for issuance upon the exercise of stock options. The Plan is designed as a means to retain and motivate key employees and to attract and retain key individuals as directors. The Compensation Committee administers and interprets the Plan and is authorized to grant options thereunder to all eligible employees and directors of the Company. The Plan provides for the granting of both incentive stock options (as defined in Section 422 of the Internal Revenue Code of 1986, as amended (the "Code")) and nonqualified stock options. Options are granted under the Plan on such terms and at such prices as determined by the Compensation Committee, except that the per share exercise price of incentive stock options cannot be less than the fair market value of the Common Stock on the date of grant. Each option is exercisable after the period or periods specified in the option agreement, but no option may be exercisable after the expiration of ten years from the date of grant. Options granted under the Plan are not transferable other than by will or by the laws of descent and distribution, except that nonqualified stock options may be transferred to immediate family members with the consent of the Compensation Committee. As of December 29, 2000, 3,931,536 shares of Common Stock were subject to issuance upon exercise of outstanding stock options. The Plan provides that all options become fully vested and exercisable upon a change in control of the Company, which will occur upon completion of the Offer. If the options are not continued following the change in control, the Plan provides that they will be cashed out based on their Black-Scholes value. As a condition to entering into the Merger Agreement, Marathon required that holders of approximately 90% of the outstanding stock options, including all directors and executive officers, agree that each stock option held by such holder will be canceled, with such holder becoming entitled to receive an amount of cash in respect of such stock option equal to the product of (A) the excess, if any, of (x) the Merger Consideration over (y) the exercise price per share subject to such stock option and (B) the number of shares subject to such stock option immediately prior to its cancellation. The following table provides information regarding stock options granted to the Named Executive Officers during 2000.

Completion of the Offer will result in a change in control of the Company for purposes of each of the foregoing agreements. COMPENSATION OF DIRECTORS Directors who are employees of the Company are not paid any fees or additional compensation for services rendered as members of the Board or any committee thereof. Directors who are not employees of the Company receive a fee of $20,000 annually. COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION The Compensation Committee of the Board (the "Committee") is composed of Mr. Lanza and Mr. Petersen, each of whom is a non-employee director of the Company. The Committee reviews and approves executive compensation, makes grants of long-term incentives, and determines the compensation to be paid to the Chief Executive Officer and each of the other officers of the Company. The goal of the executive compensation program is to reward executives for their performance and enhancement of stockholder value. The Company's executive compensation program is designed to attract and retain executives who are key to the long-term success of the Company and align compensation with the attainment of the Company's business goals and the increase of share value. The Company uses the same philosophy as the Committee in establishing compensation for employees other than officers. Executive compensation consists of (i) salary, (ii) annual performance bonuses, and (iii) long-term incentives. The Committee reviews executive compensation annually and makes appropriate adjustments based on (i) Company performance, (ii) individual performance and (iii) changes in an executive's duties and responsibilities. Salary. The Committee desires that overall compensation reflect the performance of each individual executive over time. Base salaries are set at levels subjectively determined by the Committee to adequately reward and retain capable executives, including the President and Chief Executive Officer. The Committee considers the importance of and skills required in a particular executive position in establishing salary. At the beginning of each fiscal year, the Committee reviews and establishes the annual salary of each officer, including the Chief Executive Officer. The Committee makes an independent, subjective determination of the appropriate level of each officer's salary to determine such amount, or if a salary has been fixed by contract which limits decreases, to determine the amount of the increase, if any. The Committee does not use any mechanical formulations or weighting of any of the factors considered. Annual Performance Incentives. During 2000, the Company had an annual bonus plan for the Chief Executive Officer and Chief Financial Officer that was based on net cash flows. Annual bonuses for the other executive officers are determined by the Committee based on the recommendations of management. Long-Term Incentives. In an effort to properly align the long-term interests of the Company's management and stockholders, the Committee may make awards under the Plan, which was approved by the full Board on March 24, 1998. The aggregate number of shares which may be issued under the Plan to all officers, directors and employees is 5,500,000. The Committee believes that the Plan enables the Company to attract and retain the highest quality managers. Under the Plan, the Committee is responsible for establishing who receives awards, the terms of the awards, requisite conditions and the size of the awards. Awards to any recipient are made by a subjective determination by the Committee, which considers the person's past performance and current responsibilities, as well as the amount of awards previously made to that person. A-10 20 CEO Compensation. Mr. Rady was elected President and Chief Executive Officer in June of 1998 and his salary was established at $120,000 to reflect his duties. Mr. Rady's annual salary was increased to $230,000 in January of 2000. Mr. Rady's salary has been increased over time to reflect his performance as the Company's Chief Executive Officer, with particular emphasis on the increases in the value of the Company as reflected in the consistent escalation of the trading prices of the Company's common stock. Section 162(m) of the Code places a limit of $1,000,000 on the amount of compensation that may be deducted by the Company in any one fiscal year with respect to the Chief Executive Officer and the other four most highly compensated individuals who are executive officers as of the end of the fiscal year. This deduction limitation, however, does not apply to certain "performance based" compensation. The Committee intends to generally design and implement compensation plans that qualify for full deductibility in accordance with Section 162(m). The Company, however, may from time to time pay other compensation to its executive officers that may not be deductible. Respectfully Submitted, David W. Lanza Kurt M. Petersen CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS Mr. Petersen is a partner in the law firm of Davis, Graham & Stubbs, LLP. During 2000, Davis, Graham provided various legal services to the Company. The fees for such services in 2000 totaled approximately $255,000. COMPLIANCE WITH SECTION 16(a) OF THE EXCHANGE ACT Section 16(a) of the Exchange Act requires the Company's executive officers and directors, and persons who beneficially own more than ten percent of the Company's Common Stock, to file reports of their beneficial ownership (Forms 3, 4, and 5, and any amendment thereto) with the Securities and Exchange Commission.

(the "Company") has entered into an agreement with Marathon Oil Company ("Marathon") pursuant to which (i) Marathon or an affiliate thereof will make a tender offer for all outstanding shares of common stock of the Company at a price of $19.00 per share, subject to certain terms and conditions, including that at least a majority of the fully diluted shares of Company common stock be validly tendered and not withdrawn prior to the expiration of the tender offer and (ii) following the completion of the tender offer, all of the remaining shares of Company common stock will be acquired by Marathon or an affiliate thereof through a merger transaction in which all such shares not held by Marathon or the Company are converted into the right to receive $19.00 per share (collectively, the "Proposed Transaction"). The terms and conditions of the Proposed Transaction are set forth in more detail in the draft of the Agreement and Plan of Merger dated December 20, 2000 between the Company, Marathon and Marathon Oil Acquisition I, Ltd. (the "Agreement"). We have been requested by the Board of Directors of the Company to render our opinion with respect to the fairness, from a financial point of view, to the Company's stockholders of the consideration to be offered to such stockholders in the Proposed Transaction. We have not been requested to opine as to, and our opinion does not in any manner address, the Company's underlying business decision to proceed with or effect the Proposed Transaction. In arriving at our opinion, we reviewed and analyzed: (1) the Agreement and the specific terms of the Proposed Transaction, (2) publicly available information concerning the Company that we believe to be relevant to our analysis, including the Company's Annual Report for the year ended December 31, 1999 and the Company's Quarterly Report for the period ended September 30, 2000, (3) financial and operating information with respect to the business, operations and prospects of the Company furnished to us by the Company, including financial projections for the Company for the period from 2001 through 2005 prepared by the Company, (4) certain estimates of proved and non-proved reserves and future production, revenue, operating costs and capital investment for the Company prepared by the Company, (5) a trading history of the Company's common stock from December 19, 1999 to the present and a comparison of that trading history with those of other companies that we deemed relevant, (6) a comparison of the historical financial results and present financial condition of the Company with those of other companies that we deemed relevant and (7) a comparison of the financial terms of the Proposed Transaction with the financial terms of certain other oil and gas transactions that we deemed relevant. In addition, we have had discussions with the management of the Company concerning the Company's business, operations, assets, financial condition, prospects, reserves, production profiles and exploration programs and have undertaken such other studies, analyses and investigations as we deemed appropriate. B-1 28 In arriving at our opinion, we have assumed and relied upon the accuracy and completeness of the financial and other information used by us without assuming any responsibility for independent verification of such information and have further relied upon the assurances of management of the Company that they are not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the financial projections of the Company and the estimates of future production, revenue, operating costs and capital investment for the Company, each as prepared by the Company, upon advice of the Company, we have assumed that such projections and estimates have been reasonably prepared on a basis reflecting the best currently available estimates and judgements of the Company's management as to the future performance of the Company, and that the Company will perform substantially in accordance with such projections and estimates. However, for purposes of our analysis, we also have considered certain somewhat more conservative assumptions which resulted in certain adjustments to the projections and estimates of the Company. We have discussed these adjusted projections and estimates with the management of the Company and they have agreed with the appropriateness of the use of such adjusted projections and estimates in performing our analysis. In arriving at our opinion, we have not conducted a physical inspection of the properties and facilities of the Company and have not made or obtained any evaluations or appraisals of the assets or liabilities of the Company. In addition, you have not authorized us to solicit, and we have not solicited, any indications of interest from any third party with respect to the purchase of all or a part of the Company's business. Our opinion necessarily is based upon market, economic and other conditions as they exist on, and can be evaluated as of, the date of this letter. Based upon and subject to the foregoing, we are of the opinion as of the date hereof that, from a financial point of view, the consideration to be offered to the Company's stockholders in the Proposed Transaction is fair to such stockholders. We have acted as financial advisor to the Company in connection with the Proposed Transaction and will receive a fee for our services which is contingent upon the consummation of the Proposed Transaction. In addition, the Company has agreed to indemnify us for certain liabilities that may arise out of the rendering of this opinion. We also have performed various investment banking services for Marathon in the past and have received customary fees for such services. In the ordinary course of our business, we actively trade in the securities of the Company and Marathon for our own account and for the accounts of our customers and, accordingly, may at any time hold a long or short position in such securities. This opinion is for the use and benefit of the Board of Directors of the Company and is rendered to the Board of Directors in connection with its consideration of the Proposed Transaction. This opinion is not intended to be and does not constitute a recommendation to any stockholder of the Company as to whether to accept the consideration to be offered to the stockholders in connection with the Proposed Transaction.
