(the "Company"), each of which is a Delaware corporation, hereby enter into this Agreement dated as of March 17, 2002. PRELIMINARY STATEMENT On the terms and subject to the conditions this Agreement contains, Parent proposes to acquire the Company in a two-step transaction. The first step would be a tender offer by Sub for all the outstanding shares of the Company's common stock, and the second step would be a follow-on merger between Sub and the Company in which the Company would become the surviving corporation. The board of directors of the Company has: o determined that Parent's proposed tender offer and merger are fair to and in the best interests of the Company's stockholders; o declared the agreement of merger this Agreement contains advisable and resolved to recommend that the holders of the Company's common stock accept that offer and adopt that agreement of merger; and o authorized the Company to enter into this agreement. AGREEMENT In consideration of the premises and the covenants and other undertakings this Agreement contains, the parties, intending to be legally bound hereby, agree as follows: ARTICLE ONE THE OFFER Section 1.01. The Offer. (a) As soon as practicable after the date of this Agreement, and in any event during the period of seven business days beginning on the day of the first public announcement that Parent and the Company have entered into this Agreement, Sub will commence the Offer. The consideration Sub will pay under the Offer for Shares validly tendered and not subsequently properly withdrawn will be: (1) $2.84 per Share, net to the seller in cash and without interest; or (2) such greater consideration per Share, if any, as Sub may, in its sole discretion, offer in the Offer Documents to pay for each of those Shares. If any party terminates this Agreement under Article Nine at any time prior to the acceptance for payment by Sub of Shares under the Offer, Sub may, in its sole discretion, without the consent of the Company and notwithstanding Section 1.01(b) to the contrary, make any change in the terms and conditions of the Offer and revise the Offer Documents accordingly. (b) The obligation of Sub to accept for payment and pay for Shares validly tendered in the Offer and not subsequently properly withdrawn will be subject to the Offer Conditions. Sub expressly reserves the right, in its sole discretion, to waive any of the Offer Conditions or make any change in the terms and conditions of the Offer, except that, without the prior written consent of the Company, Sub will not: (1) waive or make any change in the Minimum Tender Condition; (2) reduce the maximum number of Shares it will purchase under the Offer; (3) decrease the Offer consideration or, other than by adding consideration, change the form of the Offer consideration; or (4) make any change in or addition to the Offer Conditions or otherwise amend the Offer in a manner adverse to the holders of Common Stock. For purposes of clause (4) above, none of the following will constitute a change in the Offer in a manner adverse to the holders of Common Stock: (1) any increase in or addition to the Offer consideration; or (2) any extension of the Offer beyond the then scheduled Expiration Date: (A) for any period any applicable Governmental Requirement or any interpretation thereof or position thereunder by the SEC may require; (B) in increments of not more than five business days each, if Parent has reasonably determined that any Offering Condition is not capable of being satisfied on or prior to that scheduled Expiration Date; (C) for one or more periods, up to a total of 10 business days for all those periods, if, notwithstanding that all Offer Conditions are satisfied or waived by Sub, to the extent waivable by Sub, as of that scheduled Expiration Date, less than 90% of all outstanding Shares have been validly tendered and not subsequently properly withdrawn; or (D) for any period or periods, if, prior to the acceptance for payment by Sub of Shares under the Offer, the Company has terminated this Agreement under Section 9.01(a)(4). (c) As soon as practicable on the Offer Commencement Date, Parent and Sub will file the Schedule TO with the SEC. Thereafter, in each case as and to the extent any applicable federal securities law so requires, Parent will: (1) promptly correct any information in the Offer Documents or the Schedule 14D-9 which is or has become false or misleading in any material respect concerning it or its Affiliates or the Company, provided that, in the case of information concerning the -2- Company, the Company shall have furnished the corrected information to Parent under Section 1.02(b); (2) cause the Schedule TO, as so corrected or otherwise changed, to be promptly filed with the SEC; and (3) take all lawful action necessary to cause the Offer Documents, as originally filed with the SEC and as thereafter so corrected or otherwise changed, to be disseminated to the holders of Shares. (d) For purposes of Section 7.05, Parent will supply to the Company in writing and be solely responsible for any information concerning Parent and Sub and their nominees, directors, officers and Affiliates which Section 14(f) of the Exchange Act and Exchange Act Rule 14f-1 require be disclosed to the Company's stockholders. (e) Parent will provide to Sub the funds necessary to enable Sub, as soon as practicable after the Offer expires and the satisfaction or waiver of the Offer Conditions, to accept for payment and pay for all Shares validly tendered in the Offer and not subsequently properly withdrawn. (f) In this Section 1.01, the terms "commence" and "public announcement" have the meanings Exchange Act Rule 14d-2 specifies. Section 1.02. Company Actions. (a) The Company hereby approves of and consents to the Offer and the agreement of merger this Agreement contains and represents and warrants to Parent and Sub that the Company Board, at a meeting duly called and held, has duly by the vote of directors which the Charter Documents of the Company require adopted resolutions: (1) confirming the Company Board's determination that the Offer and the Merger are fair to and in the best interests of the Company's stockholders; (2) approving and consenting to this Agreement and the transactions it contemplates, including the Offer and the Merger, which approval and consent are sufficient to render the Section 203 Restrictions inapplicable to the consummation of the Offer or the Merger; (3) declaring the advisability of this Agreement, including the agreement of merger it contains; and (4) resolving to recommend to the holders of Shares that they accept the Offer and adopt this Agreement, including the agreement of merger it contains; provided, however, that prior to the consummation of the Offer, the Company Board will have the right, under the circumstances Section 6.02(b) describes, to withdraw that recommendation and recommend that the holders of Shares reject the Offer and the agreement of merger this Agreement contains. -3- The Company hereby consents to the inclusion in the Offer Documents of the recommendation of the Company Board to which clause (4) above refers. Each director and executive officer of the Company has advised the Company Board that he intends to tender all his Shares in the Offer for so long as no party has terminated this Agreement under Article Nine. (b) As soon as practicable on or after the Offer Commencement Date, the Company will: (1) file the Schedule 14D-9 with the SEC; and (2) promptly commence mailing the Schedule 14D-9 to its stockholders. The Company will, if Parent so requests, include in the Schedule 14D-9 the information Section 14(f) of the Exchange Act and Exchange Act Rule 14f-1 require be disclosed to the Company's stockholders in connection with the performance by the Company of its obligations under Section 7.05. Thereafter, in each case as and to the extent any applicable federal securities law so requires, the Company will: (1) promptly correct any information in the Offer Documents or the Schedule 14D-9 which is or has become false or misleading in any material respect concerning it or its Affiliates or Parent and its Affiliates, provided that, in the case of information concerning Parent and its Affiliates, Parent shall have furnished the corrected information to the Company under Section 1.01(c); (2) cause the Schedule 14D-9, as so corrected or otherwise changed, to be promptly filed with the SEC; and (3) take all lawful action necessary to cause the Schedule 14D-9, as originally filed with the SEC and as thereafter so corrected or otherwise changed, to be disseminated to the holders of Shares. (c) In connection with the Offer, the Company will: (1) cause its transfer agent to furnish Sub promptly with (A) mailing labels containing the names and addresses of the record holders of Shares as of a recent date and of those persons becoming record holders subsequent to that date and (B) copies of all lists of stockholders, security position listings and computer files and all other information in the Company's possession or control regarding the beneficial owners of Common Stock; and (2) furnish to Sub such information and assistance, including updated lists of stockholders, security position listings and computer files, as Parent may reasonably request in communicating the Offer to the Company's stockholders. Subject to the requirements of applicable law, and except for such steps as are necessary to disseminate the Offer Documents and any other documents necessary to -4- consummate the Merger, Parent and Sub and their agents will hold in confidence the information any such labels, listings and files contain, will use that information only in connection with the Offer and the Merger and, if this Agreement is terminated, will, on request, deliver, and will use their best efforts to cause their agents to deliver, to the Company all copies of and any extracts or summaries from that information then in their possession or control.

ARTICLE THREE EFFECT OF THE MERGER ON THE CAPITAL STOCK OF THE CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES Section 3.01. Effect on Capital Stock. (a) As of the Effective Time and without any action on the part of any holder of Common Stock or Capital Stock of Sub: (1) Capital Stock of Sub. The theretofore issued and outstanding shares of Capital Stock of Sub will convert into and become 1,000 validly issued, fully paid and nonassessable shares of New Common Stock; (2) Treasury Common Stock and Parent-Owned Common Stock. Each Share issued and outstanding immediately prior to the Effective Time which any Company Entity or Parent Entity then owns automatically will be cancelled and retired and cease to exist, and no consideration will be delivered in exchange therefor; (3) Conversion of Common Stock. Except as clause (2) above otherwise provides and subject to the provisions of clause (4) below, each Share issued and outstanding immediately prior to the Effective Time automatically will (A) convert into the right, and solely the right, to receive the Merger Consideration, less any required withholding taxes, on surrender of the Certificate representing that Share and (B) be cancelled and retired and cease to exist; and (4) Dissenting Shares. No Dissenting Share will convert into the right to receive the Merger Consideration, except that, if under the Appraisal Statute the right to an appraisal of that Dissenting Share thereafter ceases prior to that appraisal, that Dissenting Share will be treated as a Share that had converted as of the Effective Time into the right to receive the Merger Consideration under clause (3) above. (b) Rights of Certificate Holders. Each holder of a Certificate will, as of the Effective Time and thereafter, cease to have any rights respecting the shares that Certificate represented immediately prior to the Effective Time other than: (1) if those shares are not Dissenting Shares, the right to receive the Merger Consideration in respect of those shares under Section 3.01(a)(3); or (2) if those shares are Dissenting Shares, the rights the Appraisal Statute and Section 3.01(a)(4) provide. -6- (c) Control of Appraisal Process. If the Company receives any demand for an appraisal of Common Stock under the Appraisal Statute, it will promptly notify Parent of that demand and will not, without the prior written consent of Parent, offer, or accept an offer, to settle, or make or otherwise commit to make any payment in respect of, any such demand. Parent will have the right to participate in and direct all negotiations and proceedings with respect to all such demands. Section 3.02. Derivative Securities and Derivative Securities Plans. Each party will comply with the provisions of Schedule 3.02, which the parties incorporate herein by this reference. Section 3.03. Exchange of Certificates. (a) Prior to the Effective Time, Parent will designate the Paying Agent and from time to time will make or cause to be made available to the Paying Agent funds in the amounts and at the times necessary for the payment of the Merger Consideration on surrender of Certificates. Any and all interest earned on funds made available to the Paying Agent hereunder will belong to and be turned over to Parent. (b) As soon as reasonably practicable after the Effective Time, the Paying Agent will mail to each holder of record of a Certificate: (1) a letter of transmittal, which will specify that delivery will be effected, and risk of loss and title to Certificates will pass, only on delivery of Certificates to the Paying Agent and will be in a form and have such other provisions as Parent may specify; and (2) instructions for use in effecting the surrender of Certificates in exchange for the Merger Consideration. On surrender of a Certificate for cancellation to the Paying Agent or to such other agent or agents as Parent may appoint, together with that letter of transmittal, duly executed, and such other documents as the Paying Agent reasonably may require, the holder of that Certificate will be entitled to receive for each Share that Certificate formerly represented the amount of cash equal to the Merger Consideration, and that Certificate forthwith will be cancelled. In the event of a transfer of ownership of Converted Shares which is not registered in the transfer records of the Company, payment may be made to a Person other than the Person in whose name the Certificate so surrendered is registered, if that Certificate is properly endorsed or otherwise in proper form for transfer and the Person requesting that payment: (1) pays any transfer or other Taxes the payment to a Person other than the registered holder of that Certificate necessitates; or (2) establishes to the satisfaction of the Surviving Corporation that the Tax has been paid or is not applicable. No interest will accrue or become payable on the cash payable on the surrender of any Certificate. -7- (c) All cash paid on the surrender of Certificates in accordance with the terms of this Article Three will be deemed to have been paid in full satisfaction of all rights pertaining to the Converted Shares those Certificates theretofore represented. At the Effective Time, the stock transfer books of the Company will close, and there will be no further registration of transfers on the stock transfer books of the Surviving Corporation of the Converted Shares that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation or the Paying Agent for any reason, they will be cancelled and exchanged as this Article Three provides. (d) None of Parent, the Surviving Corporation or the Paying Agent will be liable to any Person in respect of any cash delivered to a public official under any applicable abandoned property, escheat or similar law. ARTICLE FOUR REPRESENTATIONS AND WARRANTIES OF THE COMPANY Except as the Company Disclosure Letter sets forth, the Company represents and warrants to Parent and Sub as follows: Section 4.01. Organization; Power. Each Company Entity is a corporation duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation and has all requisite corporate power and authority under those laws and its Charter Documents to own or lease and operate its properties and to carry on its business as now being conducted. Each Company Entity is duly qualified or licensed to do business and in good standing in each jurisdiction in which property it owns, leases or operates is located or the nature of the business it conducts makes that qualification or licensing necessary, except where the failures of all Company Entities to be so duly qualified or licensed and in good standing, individually or in the aggregate, would not have a Company Material Adverse Effect or prevent or materially delay the consummation of the Offer or the Merger. The Company has made available to Parent complete and correct copies of the Charter Documents of the Company and each of the other Company Entities, in each case as amended to the date of this Agreement. The respective Charter Documents of the Company Entities, other than the Company, do not contain any provision limiting or otherwise restricting the ability of the Company to control those Entities. Schedule 4.01 contains an accurate list of all the Subsidiaries of the Company. The Company owns all the outstanding shares of Capital Stock of each other Company Entity, directly or indirectly through one or more of the other Company Entities, free and clear of all liens, and all those shares are duly authorized, validly issued, fully paid and nonassessable. Section 4.02. Capitalization. As of the date of this Agreement, the authorized Capital Stock of the Company is comprised solely of: (1) 40,000,000 shares of Common Stock of which, as of March 1, 2002, 19,121,568 shares were issued and outstanding and no shares were treasury shares; and -8- (2) 5,000,000 shares of Preferred Stock, of which, as of March 1, 2002, no shares were issued and outstanding. As of March 1, 2002: (1) 2,653,836 shares of Common Stock were reserved for issuance on the exercise of Options then issued and outstanding under the Option Plan; and (2) 566,250 shares of Common Stock were reserved for issuance on the exercise of Warrants then issued and outstanding. Since March 1, 2002, no Options or Warrants have been granted and no shares of Common Stock have been issued except for shares of Common Stock issued: (1) on the exercise of Options and Warrants outstanding on that date; (2) as employer's contributions under the Savings Plan as the Company Disclosure Letter sets forth; (3) on the exercise of the Options to be granted as the Company Disclosure Letter sets forth; and (4) as payment under the Current Bonus Plan as the Company Disclosure Letter sets forth. All outstanding shares of Common Stock are, and all shares of Common Stock the Company may issue under the Option Plan or on the exercise of Warrants will be, when issued in accordance with the terms thereof, duly authorized, validly issued, fully paid and nonassessable and free of any preemptive rights in respect thereto. As of the date of this Agreement: (1) no Derivative Securities of any Company Entity are outstanding other than the Options and Warrants this Section 4.02 describes above; (2) no Company Entity has outstanding any binding obligation to repurchase, redeem or otherwise acquire for value any Capital Stock of any Company Entity; and (3) the Company has delivered to Parent an accurate, complete schedule that sets forth, for each outstanding Option and Warrant, the exercise price thereof, the number of shares of Common Stock issuable on that exercise, the extent to which that Option or Warrant presently is exercisable and the expiration date and the holder thereof. Section 4.03. Authority; Enforceability. The Company has the requisite corporate power and authority to execute and deliver this Agreement and to consummate the transactions this Agreement contemplates. The execution, delivery and performance of this Agreement by the Company and the consummation of the transactions this Agreement contemplates have been duly authorized by all necessary corporate action on the part of the -9- Company, other than, with respect to the Merger, the approval of the agreement of merger this Agreement contains by the holders of the outstanding Common Stock. The Company has duly executed and delivered this Agreement, and this Agreement, assuming it constitutes valid and binding obligations of Parent and Sub, constitutes a valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except as that enforceability may be: (1) limited by any applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors' rights generally; and (2) subject to general principles of equity, regardless of whether that enforceability is considered in a proceeding in equity or at law. Section 4.04. Consents and Approvals; No Violations. Neither the execution, delivery or performance of this Agreement by the Company nor the consummation of the transactions this Agreement contemplates will: (1) conflict with or result in any breach of any provision of the Charter Documents of any Company Entity; (2) require any Governmental Approval, except (A) as the Exchange Act, the DGCL and state securities or blue sky laws may require and (B) where failures to obtain or effect Governmental Approvals would not have a Company Material Adverse Effect; (3) result in a violation or breach of, or constitute, with or without due notice or lapse of time or both, a default, or give rise to any right of termination, amendment, cancellation or acceleration, under, any of the terms, conditions or provisions of any note, bond, mortgage, indenture, lease, license, contract, agreement, option, warrant or other instrument or obligation to which any Company Entity is a party or by which any of its properties or assets may be bound; or (4) violate any Governmental Requirement applicable to any Company Entity or any of its properties or assets; except, in the case of clauses (3) and (4), for violations, breaches or defaults that would not have, individually or in the aggregate, a Company Material Adverse Effect or prevent or materially delay the consummation of the Offer or the Merger. Section 4.05. SEC Reports and Financial Statements. Each Company Entity has timely filed with the SEC, and has made available to Parent true and complete copies of, all SEC Documents the federal securities laws have required it to so file. Each of those SEC Documents, as of its date: (1) complied in all material respects with the requirements of the Exchange Act or the Securities Act, as applicable; and -10- (2) did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading, in light, in the case only of SEC Documents filed under the Exchange Act, of the circumstances under which they were made. The consolidated financial statements of the Company included in any SEC Document, in fact or by incorporation by reference: (1) complied as to form in all material respects with the applicable accounting requirements and the published rules and regulations of the SEC with respect thereto; (2) were prepared in accordance with GAAP, except, in the case of unaudited quarterly statements on Exchange Act Form 10-Q, as that form otherwise permitted, applied on a consistent basis during the periods presented, except as the notes thereto indicate otherwise; and (3) presented fairly in all material respects the consolidated financial position of the Company and its consolidated Subsidiaries as of the dates of the balance sheets those financial statements include and the consolidated results of their operations and their consolidated cash flows for the periods ended on those dates, subject, in the case of unaudited quarterly statements, to normal year-end audit adjustments. The audited consolidated financial statements of the Company for the year ended December 31, 2001 will not differ in any adverse respects, individually or in the aggregate, Material to the Company Entities from the unaudited consolidated financial statements of the Company for the year ended December 31, 2001, a true and correct copy of which is attached to the Company Disclosure Letter. The Company is, and the Company Entities considered as a whole are not "insolvent," as the federal bankruptcy code uses the quoted term. Section 4.06. Absence of Certain Changes or Events. Except as the Filed SEC Documents disclose, since the Current Audited Balance Sheet Date, each Company Entity has conducted its business only in the ordinary course, and there has not occurred: (1) any Company Material Adverse Effect; (2) any declaration, setting aside or payment of any dividend or other distribution with respect to the Capital Stock of any Company Entity or any redemption, purchase or other acquisition of any of that Capital Stock; (3) any split, combination or reclassification of any Capital Stock of any Company Entity or any issuance or the authorization of any issuance of any other securities in respect of, in lieu of or in substitution for shares of that Capital Stock; (4) any granting, or any commitment or promise to grant, by any Company Entity to any officer of any Company Entity of (A) any increase in compensation, except in the ordinary course of business, including in connection with promotions, consistent -11- with prior practice or as employment agreements in effect as of the Current Audited Balance Sheet Date required or (B) any increase in severance or termination pay, except as part of a standard employment package to any person promoted or hired, but not including the five most highly compensated executive officers of the Company, or as employment, severance or termination agreements in effect as of the Current Audited Balance Sheet Date required; (5) except for termination arrangements in the ordinary course of business consistent with past practice with employees other than any executive officer of the Company, any entry by any Company Entity into any employment, severance or termination agreement with any officer of any Company Entity; (6) any increase in, or any commitment or promise to increase, benefits payable or available under any pre-existing Benefit Plan, except in accordance with the pre-existing terms of that Benefit Plan, any establishment of, or any commitment or promise to establish, any new Benefit Plan, any amendment of any existing stock options, stock appreciation rights, performance awards or restricted stock awards or, except in accordance with and under pre-existing compensation policies, any grant, or any commitment or promise to grant, any stock options, stock appreciation rights, performance awards, or restricted stock awards; (7) any damage to or any destruction or loss of physical properties any Company Entity owns or uses, whether or not covered by insurance, that in the aggregate have had or reasonably could be expected to have a Company Material Adverse Effect; (8) any reevaluations by the Company Entities of any of their assets which, in accordance with GAAP, the Company will reflect in its consolidated financial statements, including any impairment of assets, and which in the aggregate are Material to them; or (9) any material change in accounting methods, principles or practices by the Company. Section 4.07. No Undisclosed Liabilities. Except as and to the extent the Current Audited Financial Statements, or the financial statements any subsequently Filed SEC Document contains, include an accrual or reserve therefor or otherwise disclose, no Company Entity has any liabilities or obligations of any nature, whether or not accrued, contingent or otherwise, that GAAP would require to be reflected on a consolidated balance sheet of the Company and its consolidated Subsidiaries, including the notes thereto, except for liabilities or obligations they incurred in the ordinary course of business since the date of the most recently Filed SEC Document that have not had and will not have, individually or in the aggregate, a Company Material Adverse Effect. Section 4.08. Information Supplied. No information the Company has supplied or will supply specifically for inclusion or incorporation by reference in the Offer Documents or the Schedule 14D-9, at the respective times those documents are filed with the SEC or first published, sent or given to the Company's stockholders, contained or will contain any untrue statement of a material fact or omitted or will omit to state any material fact required to be stated -12- therein or necessary in order to make the statements therein, in light of the circumstances under which they were or are made, not misleading, except that the Company makes no representation or warranty with respect to statements made or incorporated by reference in the Schedule 14D-9 which constitute information Parent or Sub has supplied or may hereafter supply in writing specifically for inclusion or incorporation by reference in the Schedule 14D-9. The Schedule 14D-9 will comply as to form in all material respects with the applicable requirements of the Exchange Act. Section 4.09. Benefit Plans.

(j) The Company Entities have no contract, commitment, obligation or intention, whether legally binding or not, to establish or adopt any new or additional plans or other arrangements that would constitute Benefit Plans if adopted, or to increase the benefits under any existing Benefit Plan. Section 4.11. Litigation. Except as the Filed SEC Documents disclose, and except for suits filed in connection with the Offer, no actions, claims, investigations, proceedings or suits are pending or, to the knowledge of the Company, threatened against Company Entities by or before any Governmental Authority the outcomes of which, individually or in the aggregate, reasonably could be expected to have a Company Material Adverse Effect or prevent or materially delay the consummation of the Offer or the Merger.

Section 4.13. Reserve Information. The Company has delivered to Parent prior to the date of this Agreement the definitive report of Ryder Scott Company, independent petroleum engineers, on the Company's proved reserves as of December 31, 2001 together with the written acknowledgment by Ryder Scott Company that the report so delivered is as represented and warranted hereby. The underlying factual information provided to Ryder Scott Company, to the extent that Ryder Scott Company relied on it in the preparation of that report on the Company's proved reserves as of December 31, 2001, was, at the time of delivery, true and correct in all material respects, except for such errors as, individually or in the aggregate, could not reasonably be expected to have a Company Material Adverse Effect.

All those returns are complete and correct. Each Company Entity has paid, or the Company has paid on its behalf, all Taxes those returns showed as due and all Taxes for which no return was required to be filed. -17- (b) No Tax return of any Company Entity is under audit or examination by any taxing authority, and no Company Entity has received any written or oral notice of any such audit or examination.

(e) Any disallowance of a deduction under Section 162(m) of the Code for employee remuneration will not apply to any amount paid or payable by any Company Entity under any contract, Option Plan, Benefit Plan, program, arrangement or understanding currently in effect. (f) Any amount or other entitlement that could be received, whether in cash or property or the vesting of property, as a result of any of the transactions this Agreement contemplates by any employee, officer or director of the Company or any of its Affiliates who is a "disqualified individual," as proposed Treasury Regulation Section 1.280G-1 defines that term, under any employment, severance or termination agreement, other compensation arrangement or Benefit Plan currently in effect would not be characterized as an "excess parachute payment," as Section 280G(b)(1) of the Code defines that term. (g) Each Company Entity has timely filed, or caused to be timely filed on its behalf, all Royalty Returns any contract or Governmental Requirement has required it to file, and all those Royalty Returns are true, complete and accurate in all material respects as provided for under any contract or by any applicable Governmental Requirement.

(h) For purposes of Article Nine, no representations Section 4.09 and this Section 4.14 contain (each, a "Relevant Representation") will be deemed to be untrue unless all untruths the Relevant Representations contain cumulatively reasonably could be expected to have a Company Material Adverse Effect. Section 4.15. State Takeover Statutes. The Company Board has approved the Offer, the Merger and this Agreement, and that approval is irrevocable and sufficient to render the Section 203 Restrictions inapplicable to the Offer, the Merger and this Agreement and the transactions this Agreement contemplates. To the Company's knowledge, no other state takeover statute or similar Governmental Requirement applies or purports to apply to the Offer, the Merger, this Agreement or any of the transactions this Agreement contemplates. Section 4.16. Brokers; Fees and Expenses. No Company Entity has, directly or indirectly, agreed to pay or incurred any obligation to pay any broker, investment banker, financial advisor or other Person, other than the Company Financial Advisor and Randall & Dewey, Inc., the fees and expenses of which the Company will pay, any broker's, finder's, financial advisor's or other similar fee or commission in connection with the transactions this Agreement contemplates.

The representations and warranties in Section 7.17 of the Credit Agreement are true and correct.

(d) Nothing this Section 6.02 contains will prohibit the Company from taking and disclosing to its stockholders a position Exchange Act Rule 14e-2(a) contemplates or from making any disclosure to the Company's stockholders if, in the opinion of the Company Board, after consultation with counsel, failure so to disclose would be inconsistent with the fiduciary duties of its members to the Company's stockholders under Delaware law; provided, however, that neither the Company nor the Company Board or any committee thereof will, except as Section 6.02(b) otherwise permits, withdraw or modify, or propose to withdraw or modify, the Company Board's position with respect to the Offer and the agreement of merger this Agreement contains or approve or recommend, or propose to approve or recommend, a Superior Takeover Proposal. (e) During any period of four business days which Section 6.02(b) describes, the Company will not, and will not permit any other Company Entity to, enter into any binding agreement respecting any Superior Takeover Proposal. If, during or after any such period, the Company changes its intention to enter into any such binding agreement, the Company promptly will notify Parent of that change and its particulars. -27- Section 6.03. Other Actions. The Company will not, and will not permit any other Company Entity to, take any action that would result in: (1) any of the representations and warranties of the Company in this Agreement which are qualified as to materiality or a Company Material Adverse Effect becoming untrue; (2) any of those representations and warranties which are not so qualified becoming untrue in any material respect; or (3) any of the Offer Conditions not being satisfied, subject to the Company's right to take the actions Section 6.02 expressly permits it to take. ARTICLE SEVEN ADDITIONAL AGREEMENTS Section 7.01. Effecting the Merger; Stockholder Approval. (a) If Parent Entities own at least 90% of the outstanding Shares after Sub consummates the Offer, the parties hereto will take all actions necessary to effect the Merger under Section 253 of the DGCL as soon as practicable after that consummation. (b) If Parent and Sub cannot or choose not to effect the Merger under Section 253 of the DGCL, the parties will effect the Merger under Section 251 of the DGCL as soon as practicable after complying with the applicable informational requirements of the Exchange Act, and the Company will submit the agreement of merger this Agreement contains to its stockholders for the purpose of their acting on that agreement notwithstanding that the Company Board, having heretofore declared that agreement advisable, may have determined after the date of this Agreement that that agreement is no longer advisable and recommended that its stockholders reject it. (c) If Parent will effect the Merger under Section 251 of the DGCL and, in connection therewith, the Company must furnish to its stockholders an information statement under Section 14(c) of the Exchange Act, the Company will, at Parent's request, as soon as practicable following the consummation of the Offer, prepare and file a preliminary information statement with the SEC and will use its reasonable best efforts to respond to any comments of the SEC or its staff and to cause that information statement to be mailed to the Company's stockholders as promptly as practicable after responding to all those comments to the satisfaction of that staff. The Company will notify Parent promptly of the receipt of any comments from the SEC or its staff and of any request by the SEC or its staff for amendments or supplements to that information statement or for additional information and will supply Parent with copies of all correspondence between the Company or any of its Representatives and the SEC or its staff with respect to the information statement or the Merger. If at any time any event occurs that an amendment or supplement to the information statement should set forth, the Company will promptly prepare and mail to its stockholders that amendment or supplement. The Company will not mail any information statement, or any amendment or supplement thereto, to which Parent reasonably objects. -28- (d) In connection with the Merger, the Company will comply with the applicable notice requirements of the Appraisal Statute. (e) Parent will cause all Shares that all Parent Entities own to vote in favor of the agreement of merger this Agreement contains if it is to be effected under Section 251 of the DGCL. Section 7.02. Access to Information. On reasonable notice and subject to any restrictions that confidentiality agreements to which the Company is subject contain, from which restrictions the Company will use reasonable efforts to be released, the Company will: (1) afford to Parent and its Representatives access, during normal business hours at any time prior to the Effective Time, to all the properties, books, contracts, commitments and records of the Company Entities; and (2) furnish promptly to Parent (A) a copy of each report, schedule, registration statement and other document filed or received by it during such period under the federal securities or Tax laws and (B) all other information concerning its business, properties and personnel as Parent reasonably may request. The Company will deliver to Parent copies of its audited consolidated financial statements for the year ended December 31, 2001, together with the report of Deloitte & Touche LLP thereon, promptly after they become available to the Company. Except as the Company otherwise may agree, unless and until Parent Entities own at least a majority of the outstanding Shares, and notwithstanding termination of this Agreement, Parent will keep, and will cause its Representatives and Affiliates to keep, all Confidential Information of the Company Entities confidential and not to disclose any of that Confidential Information to any Person other than those Representatives and Affiliates and then only on a confidential basis; provided, however, that Parent or Sub may disclose that Confidential Information: (1) as any applicable Governmental Requirement may require; or (2) as any Governmental Authority may request. Neither Parent nor any of its Affiliates will use any Confidential Information of the Company Entities in any manner detrimental to the Company or its stockholders and, in the event any party terminates this Agreement for any reason under Article Nine, Parent will, and will cause Sub to, promptly return all that Confidential Information to the Company. Section 7.03. Reasonable Efforts. Each party agrees to use its reasonable efforts to: (1) take all actions necessary to comply promptly with all Governmental Requirements applicable to it with respect to the Offer or the Merger, which actions will include furnishing all information hereafter required to be filed in connection with approvals of or filings with any other Governmental Authority, and promptly cooperate -29- with and furnish information to each other in connection with any such requirements imposed upon any of them or their Affiliates in connection with the Offer or the Merger; and (2) take all reasonable actions necessary to obtain, and will cooperate with each other in obtaining, any Governmental Approval of, or any exemption by, any Governmental Authority or other public or private third party required to be obtained or made by Parent, Sub or the Company or any of their respective Affiliates in connection with the Offer or the Merger or the taking of any action those transactions or this Agreement contemplate. Parent will cause Sub to comply with its obligations under this Agreement. Section 7.04. Benefits. Each party will comply with the provisions Schedule 7.04 sets forth, which the parties incorporate herein by this reference. Section 7.05. Directors. Promptly on the acceptance for payment of, and payment for, any Shares by Sub in the Offer, Sub will be entitled to designate such number of members of the Company Board as will give Sub, subject to compliance with Section 14(f) of the Exchange Act, at least a majority of the members of the whole Company Board, and the Company will, at that time, cause Sub's nominees to be so elected by the then constituted Company Board; provided, however, that if Sub's nominees are so elected, then, until the Effective Time, the Company Board will have at least two directors who are Independent Directors. Subject to applicable Governmental Requirements, the Company will take all action Parent reasonably may request to effect the Company's compliance with this Section 7.05. Section 7.06. Fees and Expenses. (a) Except as Section 7.06(b) and (c) otherwise provide, each party will pay the fees and expenses it incurs in connection with the Offer, the Merger, this Agreement and the transactions this Agreement contemplates, whether or not the Offer or the Merger is consummated.

The Company must pay the Termination Fee to Parent by wire transfer of immediately available funds to Parent's account Schedule 7.06 specifies: (1) if an event clause (1) of the preceding sentence describes occurs, as promptly as is reasonable practicable, but in no event later than two business days, after that occurrence; and (2) if an event clause (2) or (3) of the preceding sentence describes occurs, concurrently with that occurrence. (c) If the Company becomes obligated to pay the Termination Fee to Parent under Section 7.06(b), it also will reimburse Parent for all out-of-pocket fees and expenses reasonably incurred by Parent and Sub from and after January 1, 2002 in connection with the Offer, the Merger, this Agreement and the transactions this Agreement contemplates and the enforcement of their rights hereunder. If the Company becomes entitled to, and does, terminate this Agreement under Section 9.01(a)(5), Parent will reimburse the Company for all out-of-pocket fees and expenses reasonably incurred by the Company from and after January 1, 2002 in connection with the Offer, the Merger, this Agreement and the transactions this Agreement contemplates and the enforcement of its rights hereunder. Section 7.07. Indemnification; Insurance. (a) All rights to indemnification for acts or omissions occurring before the Effective Time now existing in favor of the current or former directors or officers of the Company as its Charter Documents or contractual arrangements provide on the date of this Agreement, or as applicable law otherwise provides, will survive the Merger and continue in full force and effect in accordance with their terms. (b) For six years from the Effective Time, Parent will, unless Parent elects, at its option, in writing to guarantee performance of the indemnification obligations to which Section 7.07(a) refers, maintain in effect the Company's current D&O Insurance covering those persons who are currently covered by the Company's D&O Insurance policy, a copy of which the Company has made available to Parent; provided, however, that Parent will extend the Company's current D&O policy in effect to cover claims made prior to the first anniversary of the Effective Time if the premium for that additional coverage does not exceed $80,000. (c) This Section 7.07 will survive the consummation of the Merger at the Effective Time, is intended to benefit the Company, Parent, the Surviving Corporation and the indemnified parties and will be binding on all successors and assigns of Parent and the Surviving Corporation. -31- Section 7.08. Antitakeover Measures. So long as the Offer remains outstanding and complies with Section 1.01(b), the Company will not at any time, notwithstanding that the Company may have terminated this Agreement under Article Nine, adopt, or permit any other Company Entity to adopt, by means of any amendment to any of its Charter Documents or any agreement on its part, any Anti-Parent Takeover Measures, including any "poison pill" rights plan or any measure to the same or similar effect as the Section 203 Restrictions. Section 7.09. Certain Litigation.

(b) The Company will not voluntarily cooperate with any third party that has sought or may hereafter seek to restrain or prohibit or otherwise oppose the Offer or the Merger and will cooperate with Parent and Sub to resist any such effort to restrain or prohibit or otherwise oppose the Offer or the Merger, unless the Company Board determines, in the good faith of its members after consultation with the Company's outside counsel, that failing so to cooperate with that third party or cooperating with Parent or Sub, as the case may be, would constitute a breach of its members' fiduciary duties under Delaware law. Section 7.10. Credit Agreement. The Company will use reasonable efforts to cause the lenders under the Credit Agreement to forbear from accelerating its indebtedness under the Credit Agreement solely as a result of the consummation of the Offer or the performance by the Company of its obligations under Section 7.05.

provided, however, that the right to terminate this Agreement under this Section 9.01(a)(2)(A) will not be available to any party whose failure to perform any of its obligations hereunder or whose breach of any of its representations and warranties herein shall have caused that right to become exercisable; or (B) if any Governmental Authority shall have issued any order, decree or ruling or taken any other action permanently enjoining, restraining or otherwise prohibiting the acceptance for payment of, or payment for, Shares under the Offer or the consummation of the Merger and that order, decree or ruling or other action shall have become final and nonappealable; (3) by Parent if, prior to the purchase of Shares under the Offer: (A) the Company Board shall have: (1) withdrawn, or modified or otherwise changed, in a manner or to an effect adverse to Parent or Sub, its approval or recommendation of the Offer or the agreement of merger this Agreement contains;

or (D) any Stockholder shall have breached any of its covenants and other agreements in Sections 2, 3, 4 and 5 of the Stockholders Agreement; (4) by the Company, if, prior to the purchase of Shares under the Offer: (A) the Company Board, by a majority vote of the whole board, has determined in the good faith of its members and on the basis of, among other facts, the advice of the Company Financial Advisor and the Company's outside counsel, that the Company has received a Superior Takeover Proposal; (B) the Company Board has directed the Company to notify Parent in writing that the Company intends to enter into a definitive agreement respecting that proposal, and the Company has delivered that notice to Parent together with either the then most current version of that agreement or an accurate, complete description of all the material terms and conditions thereof;

That amendment or supplement to this Agreement will not require any further authorization by the Company Board, whose approval of this Agreement prior to the date hereof will constitute the approval of that amendment or supplement. -35- (b) Except as Section 9.02(a) otherwise provides, the parties may amend this Agreement if and to the extent that their respective boards of directors authorize them to do so, at any time before or after the Company's stockholders have approved the agreement of merger this Agreement contains, if the DGCL requires that approval, but, after any such approval, the parties hereto may not effect any further amendment which by law requires further approval by those stockholders without that further approval. To be effective, any amendment hereto must be in a written document each party has executed and delivered to the other parties. Section 9.04. Extension; Waiver.

After a representation and warranty has terminated and expired, no claim for damages or other relief may be made or prosecuted through litigation or otherwise by any Person who would have been entitled to that relief on the basis of that representation and warranty prior to its termination and expiration.

PRELIMINARY STATEMENT Parent and its subsidiary, ECM Acquisition Company ("Sub"), a Delaware corporation, propose to enter into an agreement dated as of March 17, 2002 with the Company (the "Acquisition Agreement"). On the terms and subject to the conditions the Acquisition Agreement contains, Parent proposes to acquire the Company in a two-step transaction. The first step would be a tender offer by Sub for all the outstanding shares of the Company's common stock, and the second step would be a follow-on merger between Sub and the Company in which the Company would become the surviving corporation. The board of directors of the Company has: o determined that Parent's proposed tender offer and merger are fair to and in the best interests of the Company's stockholders; o declared the agreement of merger the Acquisition Agreement contains advisable and resolved to recommend that the holders of the Company's common stock accept that offer and adopt that agreement of merger; and o authorized the Company to enter into the Acquisition Agreement. The Stockholders collectively own approximately 53% of the shares of the Company's common stock issued and outstanding as of March 1, 2002. In order to induce Parent and Sub to enter into and thereafter perform their respective obligations under the Acquisition Agreement, the Stockholders are entering into this Agreement.

Any tender of Subject Shares by a Stockholder in accordance with this Section 2 must include the physical delivery of certificates representing those Subject Shares and the execution and delivery of a properly completed letter of transmittal with respect thereto. (b) If the Subject Securities of a Stockholder include property, securities or rights that Sub has not amended the Offer to include, this Section 2 will not require that Stockholder to tender, and Sub will not be required to amend the Offer to include, any property, securities or rights not so included. Section 3. Voting of Subject Shares. (a) If the agreement of merger the Acquisition Agreement contains is duly submitted to the stockholders of the Company for their approval or disapproval, each Stockholder will duly and properly vote all that Stockholder's Subject Shares entitled to vote on that matter in favor of the adoption of that agreement. A-2 (b) If any action or agreement is duly submitted to the stockholders of the Company which, if taken or effected, reasonably could be expected to (1) result in a breach of any representation, warranty, covenant or other agreement of the Company in or under the Acquisition Agreement, or (2) prevent, impede, interfere with, delay or postpone the consummation of the Offer or the Merger, including any Acquisition Proposal, each Stockholder will duly and properly vote all that Stockholder's Subject Shares entitled to vote on that matter against the taking of that action or the effecting of that agreement. (c) If any action by the stockholders or the Company to which Section 3(a) or (b) refers is sought to be taken by written consent in lieu of a meeting of those stockholders, each Stockholder will give or withhold that Stockholder's consent thereto to the same effect as if that action were presented for approval or disapproval at such a meeting. (d) Each Stockholder: (1) hereby irrevocably grants to, and appoints, Kathy Hogenson and Peter Robinson, or either of them, in their respective capacities as officers of Parent or Sub, and any individual who hereafter succeeds to any such office, and each of them individually, that Stockholder's proxy and attorney-in-fact, with full power of substitution, for and in the name, place and stead of that Stockholder, to vote that Stockholder's Subject Shares in accordance with this Section 3; (2) represents that any proxies that Stockholder has heretofore given in respect of any of that Stockholder's Subject Shares are not irrevocable and hereby revokes all such proxies and agrees to give all notices required to evidence that revocation; (3) acknowledges that Stockholder's understanding that Parent is entering into the Acquisition Agreement in reliance on that Stockholder's execution and delivery of this Agreement and affirms that that Stockholder is granting the irrevocable proxy this Section 3 contains in connection with Parent's execution and delivery of the Acquisition Agreement and to secure the performance by that Stockholder of that Stockholder's obligations hereunder; (4) affirms that that irrevocable proxy is coupled with an interest and may not be revoked under any circumstances; and (5) ratifies all that the proxies and attorneys-in-fact designated by that proxy lawfully may do or cause to be done in their several capacities as such and confirms that that proxy is intended to be irrevocable under the applicable Delaware law.

Section 5. Waiver of Appraisal Rights. Each Stockholder hereby waives all rights of appraisal or dissent that Stockholder has under the DGCL with respect to the Merger. Section 6. Treatment of Confidential Information. (a) Each of Michael E. Johnson, David W. Berry and David B. Christofferson (the "Receiving Stockholders"), severally and not jointly with any other Person, acknowledges that he has or may have had in the past, currently has and in the future may have access to Confidential Information of the Company Entities and Parent and its Affiliates. Each Receiving Stockholder, severally and not jointly with any other Person, agrees that he will keep confidential and not use, directly or indirectly, for his own benefit or the benefit of any business of any Person other than the Company Entities and Parent and its Affiliates, all that Confidential Information that Receiving Stockholder has or hereafter obtains and, except with the specific prior written consent of Parent, will not disclose that Confidential Information to any Person except (1) Representatives of Parent and (2) his own Representatives, provided that these Representatives, other than counsel, agree to the confidentiality provisions of this Section 6; provided, however, that, for purpose of this Section 6(a), Confidential Information a Receiving Stockholder has does not include such information as: (1) becomes known to the public generally through no fault of that Receiving Stockholder; (2) is required to be disclosed by law or the order of any Governmental Authority under color of law, provided, that prior to the disclosure by that Receiving Stockholder of any information under this clause (2), that Receiving Stockholder will give prior written notice thereof to Parent and provide Parent with the opportunity to contest that disclosure; or A-4 (3) that Receiving Stockholder reasonably believes is required to be disclosed in connection with the defense of a lawsuit against that Receiving Stockholder. In the event of a breach or threatened breach by any Receiving Stockholder of the provisions of this Section 6 with respect to any Confidential Information, Parent or the Company will be entitled to an injunction restraining that Receiving Stockholder from disclosing, in whole or in part, that Confidential Information. Nothing herein shall be construed as prohibiting Parent or the Company from pursuing any other available remedy for such breach or threatened breach, including the recovery of damages. (b) Because of (1) the difficulty of measuring economic losses as a result of the breach of the foregoing covenants in Section 6(a) and (2) the immediate and irreparable damage that would be caused to Parent or the Company for which it would have no other adequate remedy, each of the Receiving Stockholders agrees that Parent or the Company may enforce the provisions of Section 6(a) by injunctions and restraining orders against each of them who breaches any of those provisions.

(the "Company"), a Delaware corporation, to which this Agreement refers to as "Stockholders" on the signature pages hereof (the "Stockholders") hereby enter into this Agreement dated as of March 17, 2002. PRELIMINARY STATEMENT Parent and its subsidiary, ECM Acquisition Company ("Sub"), a Delaware corporation, propose to enter into an agreement dated as of March 17, 2002 with the Company (the "Acquisition Agreement"). On the terms and subject to the conditions the Acquisition Agreement contains, Parent proposes to acquire the Company in a two-step transaction. The first step would be a tender offer by Sub for all the outstanding shares of the Company's common stock, and the second step would be a follow-on merger between Sub and the Company in which the Company would become the surviving corporation. The board of directors of the Company has: o determined that Parent's proposed tender offer and merger are fair to and in the best interests of the Company's stockholders; o declared the agreement of merger the Acquisition Agreement contains advisable and resolved to recommend that the holders of the Company's common stock accept that offer and adopt that agreement of merger; and o authorized the Company to enter into the Acquisition Agreement. The Stockholders collectively own approximately 52% of the shares of the Company's common stock issued and outstanding as of March 1, 2002. In order to induce Parent and Sub to enter into and thereafter perform their respective obligations under the Acquisition Agreement, the Stockholders are entering into this Agreement. AGREEMENT In consideration of the premises and the covenants and other undertakings this Agreement contains, the parties, intending to be legally bound hereby, agree as follows: Section 1. Definitions. (a) In this Agreement: (1) the "Original Shares" of a Stockholder means the number of shares of Common Stock which appears opposite that Stockholder's name on the signature pages hereof; and (2) the "Subject Shares" of a Stockholder means that Stockholder's Original Shares together with: B-1 (A) all shares of Common Stock or other Capital Stock, all Derivative Securities, including any preferred stock purchase rights, and all other properties or rights, including any phantom securities, to which that Stockholder hereafter becomes entitled by reason of any dividend or other distribution the Company pays or makes in respect of the Common Stock or any other class or series of its Capital Stock; (B) all properties, securities and rights to which that Stockholder becomes entitled by reason of any split, combination or reclassification of the Common Stock or any other Capital Stock of the Company or any issuance by the Company in respect or lieu of or in substitution for shares of its Capital Stock; and (C) all properties, securities and rights of any type to which clause (2)(A) or (B) of this definition refers which that Stockholder purchases or otherwise acquires after the date hereof from the Company or any other Person. (b) Capitalized terms this Agreement uses, but does not define, have the meanings the Acquisition Agreement specifies. References herein to "this Agreement" are to this Agreement as it may be amended, modified or supplemented from time to time hereafter in writing by each party against which another party seeks to enforce that amendment, modification or supplement. Section 2. Option To Purchase Subject Shares. (a) Each Stockholder hereby grants to Parent an irrevocable option (each such option, a "Purchase Option") to purchase from that Stockholder at any time during the Option Exercise Period all that Stockholder's Subject Shares at a total cash option exercise price equal to the product of (1) the total number of that Stockholder's Original Shares multiplied by (2) $2.84 (each such price, a "Purchase Price"). (b) In this Section 2, "Option Exercise Period" means, if Parent becomes entitled to, and does, terminate the Acquisition Agreement under Section 9.01(a)(3) thereof or the Company becomes or purports to become entitled to, and does or purportedly does, terminate this Agreement under Section 9.01(a)(4) thereof, the period of 30 days beginning the date of that termination or purported termination; provided, however, that if the Offer Commencement Date shall have previously occurred, that 30-day period will begin on the next day following the date Sub terminates the Offer without having purchased any Shares thereunder. (c) Parent must exercise each Purchase Option in whole only and must exercise all Purchase Options at the same time. To exercise the Purchase Options, Parent must deliver to each Stockholder a written notice of Parent's intention to effect that exercise, and the closing of the purchase of the Subject Shares subject to the Purchase Options will take place: (1) in accordance with the escrow arrangement Section 2(d) describes below or, if for any reason that escrow arrangement and the deposit thereunder of the Subject Shares has not occurred when Parent exercises the Purchase Options, (2) in the office of Baker Botts LLP in Houston, Texas. B-2 In the latter case, Parent will designate in that notice the date and time of the closing, which date may be the next day after Parent has delivered that notice. At that closing, Parent will pay in respect of each Purchase Option the Purchase Price payable under that Purchase Option against delivery of the certificates representing the Subject Shares subject to that Purchase Price, duly endorsed for transfer to Parent. (d) Each Stockholder agrees to deposit as promptly as possible (1) certificates representing all of that Stockholder's Subject Shares, duly endorsed in blank with signatures guaranteed, and (2) an irrevocable power of attorney with Bank of America, Bank of New York or such other party as may be mutually agreed upon by the Parent and the Stockholders, as escrow agent (the "Escrow Agent") under an escrow agreement substantially in the form of Annex A with such changes therein, if any, as the Escrow Agent may require or as Parent and the Stockholders may agree (the "Escrow Agreement"). The irrevocable power of attorney shall authorize the Escrow Agent to effect a valid tender of such Subject Shares under and in accordance with the terms of the Offer, pursuant to the terms of the Stockholders Agreement. This shall include, without limitation, physical delivery of such certificates and the execution and delivery of a properly completed letter of transmittal and any other required documentation or instruments with respect thereto. If any Stockholder withdraws its tendered Subject Shares from the Offer in accordance with the terms of the Stockholders Agreement, the Escrow Agent shall hold such Subject Shares in escrow until Parent exercises its Purchase Option with respect thereto or the Option Exercise Period has otherwise ended. When that escrow is established (the "Escrow"), the Purchase Options may be exercised in accordance with this Section 2, by delivery to the Escrow Agent of a notice in the form of Exhibit 1 to the Escrow Agreement and the Purchase Prices thereunder. Section 3. Limitation on Competition. (a) Each Stockholder agrees, severally and not jointly with any other Person, that that Stockholder will not, during the period beginning on the date hereof and ending on the first anniversary of the date hereof (the "Non-Compete Period"), directly or indirectly, for any reason, for that Stockholder's own account or on behalf of or together with any other Person: (1) acquire or enter into an agreement to acquire, directly or through direct or indirect ownership or contract rights with respect to a Person, including without limitation whether as principal, agent, stockholder, partner, joint venturer, employer, employee or in any other capacity, any interest (an "Interest") of any kind or character in the lands or in the minerals on or under said lands whatsoever located within the Non-Compete Area (as Annex B defines that term), whether by means of lease, purchase, assignment, trade, sublease, easement, farmout, or any other form of acquisition, including any merger with or acquisition of stock or ownership interests in any other Person; or (2) call on or otherwise solicit, directly or indirectly through any Person, any natural person who is at that time employed by the Company in any managerial capacity with the purpose or intent of attracting that person from the employ of the Company. Notwithstanding the foregoing, any Stockholder may own and hold as a passive investment up to 10% of the outstanding Capital Stock of a competing Entity. In the event that a Stockholder B-3 acquires an Interest in the Non-Compete Area during the Non-Compete Period, that Stockholder (the "Acquiring Stockholder") must promptly notify Parent in writing of that acquisition, including a full description of the acquired Interest and the rights, obligations and duties with respect thereto, accompanied by a copy of any acquisition agreement and any other relevant documents. Within 30 days following that acquisition, the Acquiring Stockholder will convey, transfer and assign all its rights, titles, and interests in the Interest so acquired to the Company without consideration. (b) Because of (1) the difficulty of measuring economic losses to Parent or the Company as a result of any breach by a Stockholder of that Stockholder's covenants in Section 3(a) and (2) the immediate and irreparable damage that could be caused to Parent or the Company for which it would have no other adequate remedy, each Stockholder agrees that Parent or the Company may enforce the provisions of Section 3(a) by injunctions and restraining orders against that Stockholder if that Stockholder breaches any of those provisions. The breaching Stockholder will be responsible for, and Parent and the Company will be entitled to receive reimbursement of, all costs of enforcing their rights under this Section 3, including reasonable attorney's fees. (c) The parties each agree that Sections 3(a) and (b) impose a reasonable restraint on the Stockholders in light of the activities and business of Parent and the Company on the date hereof and the current business plans of the Company and Parent and its Affiliates. (d) The covenants in this Section 3 are severable and separate, and the unenforceability of any specific covenant in this Section 3 is not intended by any party to, and will not, affect the provisions of any other covenant in this Section 3. If any court of competent jurisdiction determines that the scope, time or territorial restrictions Section 3(a) sets forth are unreasonable as applied to any Stockholder, the parties, including that Stockholder, acknowledge their mutual intention and agreement that those restrictions be enforced to the fullest extent the court deems reasonable, and thereby will be reformed to that extent as applied to that Stockholder and any other Stockholders similarly situated. (e) All the covenants in this Section 3 are intended by each party to be, and will be construed as, an agreement independent of any other provision in this Agreement. It is specifically agreed that the time periods Section 3(a) specifies will be computed in the case of each Stockholder by excluding from that computation any time during which that Stockholder is in violation of any provision of Section 3(a). The covenants this Section 3 contains will not be affected by any breach of any other provision hereof by any party. (f) Each Stockholder, severally and not jointly with any other Person, hereby agrees that this Section 3 is a material and substantial part of the transactions the Acquisition Agreement contemplates. B-4 Section 4. Representations and Warranties. Each Stockholder represents and warrants to Parent that, as applied solely to that Stockholder, all the following representations and warranties in this Section 4 are as of the date of this Agreement, and will be immediately prior to Sub's payment for that Stockholder's Subject Shares, true and correct: (1) the Stockholder: (A) is the record and beneficial owner of, and has good and marketable title to, the Stockholder's Original Shares and, as of the date Sub consummates the Offer, all other Subject Shares the Stockholder hereafter acquires, in each case free and clear of any "adverse claim," as the applicable Uniform Commercial Code defines that term, or other lien or encumbrance; and (B) has and will have, with respect to the Original Shares, and will have, with respect to all other Subject Shares the Stockholder hereafter acquires, the sole right to Transfer and direct the voting of those securities; (2) except as the Stockholders Agreement otherwise provides, none of the Original Shares is, and none of the other Subject Shares the Stockholder hereafter acquires will be, subject to any voting trust, voting agreement or other agreement, arrangement or restriction respecting the Transfer or voting of any of those securities; (3) the Stockholder has the full power, legal capacity and authority to execute, deliver and perform the Stockholder's obligations under this Agreement.

The obligations of each Stockholder under this Agreement are several and not joint, or joint and several, with the obligations of any other Stockholder under this Agreement. Section 6.

[SEAL] ANNEX A ESCROW AGREEMENT Santos Americas and Europe Corporation ("Parent"), a Delaware corporation, the holders of outstanding common stock of Esenjay Exploration, Inc. (the "Company"), a Delaware corporation, to which this Escrow Agreement refers as "Stockholders" on the signature pages hereof (the "Stockholders") and ___________________________, as Escrow Agent ("Escrow Agent") hereby enter into this Escrow Agreement dated as of March ___, 2002 PRELIMINARY STATEMENT Parent and its subsidiary, ECM Acquisition Company ("Sub"), a Delaware corporation, have entered into an agreement dated as of March 17, 2002 with the Company (the "Acquisition Agreement").

In order to induce Parent and Sub to enter into and thereafter perform their respective obligations under the Acquisition Agreement, the Stockholders have entered into a Stockholders Agreement dated as of March 17, 2002 (the "Stockholders Agreement") and an Option Agreement dated as of March 17, 2002 (the "Option Agreement"). AGREEMENT In consideration of the premises and the covenants and other undertakings this Agreement contains, the parties, intending to be legally bound hereby, agree as follows: 1.

Escrow Agent will hold and dispose of the certificates each Stockholder deposits with it hereunder in accordance with the terms hereof. 3. Each Stockholder hereby irrevocably appoints and designates Escrow Agent as the agent, representative and attorney-in-fact for and on behalf of that Stockholder to take any and all actions on behalf of that Stockholder to effect, in accordance with the Stockholders Agreement, a valid tender of that Stockholder's Subject Shares under and in accordance with the terms of the Offer.

Following that redeposit, Escrow Agent will hold those certificates in its custody hereunder until it disposes of those certificates in accordance with Section 4 below. 4. (a) If at any time during the Option Exercise Period Parent shall deliver to Escrow Agent written notice in the form of Exhibit 1 hereto of its exercise of the Purchase Options, together with immediately available funds in the aggregate amount of the Purchase Prices payable thereunder, Escrow Agent promptly will deliver the certificates representing all Subject Shares Parent has purchased on its exercise of the Purchase Options to Parent. Escrow Agent will, promptly following its receipt of those funds, deliver to each Stockholder, in accordance with that Stockholder's written wire transfer instructions, immediately available funds in the amount of the Purchase Price to which that Stockholder is entitled. (b) If during the Option Exercise Period Parent does not exercise the Purchase Options and purchase the Subject Shares subject thereto under Section 4(a), Escrow Agent promptly will deliver to each Stockholder following the expiration of the Option Exercise Period the certificates representing that Stockholder's Subject Shares. 5. Prior to the termination of this Escrow Agreement, Escrow Agent will vote all Subject Shares that it holds or has tendered under the Offer in accordance with the written instructions of Parent. 6. Escrow Agent may resign by mailing its written notice of that resignation to the Stockholders and Parent; provided, however, that this resignation will not be effective until Parent shall have appointed a successor Escrow Agent and that successor shall have executed an Escrow Agreement substantially in the form hereof. Any successor escrow agent must be a national or state bank authorized to exercise corporate trust powers, and having a combined capital and surplus of at least $100,000,000. Escrow Agent will receive reasonable compensation for its services hereunder which Parent will pay or cause to be paid. 7. Each of the Stockholders and Parent severally represents and warrants to the Escrow Agent that it has full right, power and authority to execute and deliver this Escrow Agreement. 8. All notices, requests, claims, demands and other communications hereunder must be in writing and will be given (and will be deemed to have been duly received if so given) by personal delivery or facsimile, by mail (registered or certified mail, postage prepaid, return receipt requested), or by means of electronic communications equipment (which is confirmed) to the respective parties as follows: A-2 If to Parent, to it at: 10111 Richmond Avenue Suite 500 Houston, Texas 77042 Attention: Kathleen A.
