If Devon reasonably determines that any Santa Fe Snyder designee is unacceptable, Santa Fe Snyder and Devon will agree upon a substitute designee not later than July 15, 2000. If, prior to the Effective Time, any Santa Fe Snyder designee becomes unavailable or unwilling to serve, Santa Fe Snyder shall designate a substitute designee acceptable to Devon.

ARTICLE 3 CONVERSION OF SANTA FE SNYDER STOCK Section 3.1 CERTAIN DEFINITIONS. For purposes of this Agreement, the following terms shall have the following meanings: (a) "Devon Common Stock" shall mean the common stock, par value $.10 per share, of Devon, and the rights under the Devon Rights Agreement.

Section 3.2 CONVERSION OF SANTA FE SNYDER STOCK AND MERGER CO. STOCK. (a) At the Effective Time, each share of Santa Fe Snyder Common Stock issued and outstanding immediately prior to the Effective Time (other than shares of Santa Fe Snyder Common Stock (x) held in Santa Fe Snyder's treasury or (y) owned by Devon or any wholly-owned Subsidiary (as defined in Section 9.15) of Devon or Santa Fe Snyder) shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into the number of shares of Devon Common Stock equal to the Santa Fe Snyder Exchange Ratio, subject to adjustment as provided in Section 3.4. At the Effective Time, each share of Merger Co. common stock issued and outstanding immediately prior to the Effective Time shall, by virtue of the Merger and without any action on the part of the holder thereof, be converted into one share of Santa Fe Snyder Common Stock. (b) As a result of the Merger and without any action on the part of the holders thereof, each share of Santa Fe Snyder Common Stock shall cease to be outstanding and shall be canceled and retired and shall cease to exist, and each holder of a certificate representing any shares of Santa Fe Snyder Common Stock (a "Certificate") shall thereafter cease to have any rights with respect to such shares of Santa Fe Snyder Common Stock, except that such Certificates shall thereafter evidence (x) the number of whole shares of Devon Common Stock into which such shares are converted pursuant to Section 3.2(a) and the right to receive any dividends or distributions with respect thereto and (y) the right to receive cash for fractional shares of Devon Common Stock in accordance with Sections 3.3(b) and 3.3(e) upon the surrender of such Certificate. (c) (i) At the Effective Time, all options (individually, a "Santa Fe Snyder Option" and collectively, the "Santa Fe Snyder Options") then outstanding under the stock option plans of Santa Fe Snyder described in the Santa Fe Snyder Disclosure Letter (collectively, the "Santa Fe Snyder Stock Option Plans") shall remain outstanding following the Effective Time and cease to represent a right to acquire shares of Santa Fe Snyder Common Stock and shall be converted automatically into options to purchase shares of Devon Common Stock as provided in this Section 3.2(c). At the Effective Time, the Santa Fe Snyder Options shall, by virtue of the Merger and without any further action on the part of Devon or the holder of any Santa Fe Snyder Option, be assumed by Devon in such manner that Devon (A) is a corporation "assuming a stock option in a transaction to which Section 424(a) applied" within the meaning of Section 424 of the Code or (B) to the extent that Section 424 of the Code does not apply to any Santa Fe Snyder Option, would be such a corporation were Section 424 of the Code applicable to such option. Each Santa Fe Snyder Option assumed by Devon shall be exercisable upon the same terms and conditions as under the applicable Santa Fe Snyder Stock Option Plan and the applicable option agreement issued thereunder, except that (X) each Santa Fe Snyder Option shall be exercisable for that whole number of shares of Devon Common Stock (rounded upward to the nearest whole share) into which the number of shares of the Santa Fe Snyder Common Stock subject to such Santa Fe Snyder Option immediately prior to the Effective Time would be converted under Section 3.2(a) if such number of shares of Santa Fe Snyder Common Stock was then outstanding and (Y), the option price per share of Devon Common Stock shall be an amount 4 equal to the option price per share of Santa Fe Snyder Common Stock subject to such Santa Fe Snyder Option in effect immediately prior to the Effective Time, divided by the Santa Fe Snyder Exchange Ratio, subject to adjustment as provided in Section 3.4 (the price per share, as so determined, being rounded upward to the nearest full cent). (ii) Devon shall take all corporate action necessary to reserve for issuance a number of shares of Devon Common Stock equal to the number of shares of Devon Common Stock issuable upon the exercise of the Santa Fe Snyder Options assumed by Devon pursuant to this Section 3.2(c). From and after the date of this Agreement, except as provided in Section 6.1(f), no additional options shall be granted by Santa Fe Snyder or its Subsidiaries under the Santa Fe Snyder Stock Option Plans or otherwise. At the Effective Time or as soon as practicable, but in no event more than three business days thereafter, Devon shall file with the Securities and Exchange Commission (the "SEC") a Registration Statement on Form S-8 covering all shares of Devon Common Stock to be issued upon exercise of the Santa Fe Snyder Options and shall cause such registration statement to remain effective for as long as there are outstanding any Santa Fe Snyder Options. Section 3.3 EXCHANGE OF CERTIFICATES REPRESENTING SANTA FE SNYDER STOCK. (a) As of the Effective Time, Devon shall deposit, or shall cause to be deposited, with BankBoston, N.A. or such other party reasonably satisfactory to Devon and Santa Fe Snyder (the "Exchange Agent"), for the benefit of the holders of shares of Santa Fe Snyder Common Stock, for exchange in accordance with this Article 3, certificates representing (i) the shares of Devon Common Stock to be issued pursuant to Section 3.2 in exchange for outstanding shares of Santa Fe Snyder Common Stock and (ii) cash sufficient to pay cash in lieu of fractional shares and any dividends and other distributions pursuant to Section 3.3(b) and 3.3(e) (the "Exchange Fund"). (b) Promptly after the Effective Time, Devon shall cause the Exchange Agent to mail to each holder of record of one or more Certificates: (i) a letter of transmittal (the "Letter of Transmittal") which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as Devon and Santa Fe Snyder may reasonably specify and (ii) instructions for use in effecting the surrender of the Certificates in exchange for certificates representing shares of Devon Common Stock and cash in lieu of fractional shares. Upon surrender of a Certificate for cancellation to the Exchange Agent together with such Letter of Transmittal, duly executed and completed in accordance with the instructions thereto, the holder of such Certificate shall be entitled to receive in exchange therefor (A) a certificate representing that number of whole shares of Devon Common Stock and (B) a check representing the amount of cash in lieu of fractional shares, if any, in respect of the Certificate surrendered pursuant to the provisions of this Article 3, after giving effect to any required withholding tax, and the Certificate so surrendered shall forthwith be canceled. No interest will be paid or accrued on the cash in lieu of fractional shares and unpaid dividends and distributions, if any, payable to holders of Certificates. In the event of a transfer of ownership of Santa Fe Snyder Common Stock which is not registered in the transfer records of Santa Fe Snyder, a certificate representing the proper number of shares of Devon Common Stock, together with a check for the cash to be paid in lieu of fractional shares, shall be issued to such a transferee if the Certificate representing 5 such Santa Fe Snyder Common Stock is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer taxes have been paid. (c) Notwithstanding any other provisions of this Agreement, no dividends or other distributions declared or made after the Effective Time with respect to Devon Common Stock with a record date after the Effective Time shall be paid with respect to the shares represented by any Certificate until such Certificate is surrendered for exchange as provided herein. Subject to the effect of applicable laws, following surrender of any such Certificate, there shall be paid to the holder of the certificates representing whole shares of Devon Common Stock issued in exchange therefor, without interest, (i) at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore payable with respect to the number of whole shares of Devon Common Stock into which the shares represented by the Certificates are exchanged and not paid, less the amount of any withholding taxes which may be required thereon, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to surrender and a payment date subsequent to surrender payable with respect to such whole shares of Devon Common Stock, less the amount of any withholding taxes which may be required thereon. (d) At or after the Effective Time, there shall be no transfers on the stock transfer books of Santa Fe Snyder of the shares of Santa Fe Snyder Common Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to Devon, the presented Certificates shall be canceled and exchanged for certificates for shares of Devon Common Stock and cash in lieu of fractional shares, if any, deliverable in respect thereof pursuant to this Agreement in accordance with the procedures set forth in this Article 3. (e) No fraction of a share of Devon Common Stock will be issued, but in lieu thereof each holder of Santa Fe Snyder Common Stock otherwise entitled to receive a fraction of a share of Devon Common Stock will be entitled to receive in accordance with the provisions of this Section 3.3(e) from the Exchange Agent a cash payment in lieu of the fraction of a share of Devon Common Stock equal to the fraction multiplied by the average of the closing sales price (or, if the securities should not trade on any trading day, the average of the bid and ask prices therefor on that day) of Devon Common Stock as reported on the American Stock Exchange (the "AMEX") during the five consecutive trading days immediately preceding the Effective Date. As promptly as practicable after the determination of the amount of cash, if any, to be paid to holders of fractional interests, the Exchange Agent will notify Devon, and Devon will deposit the necessary cash with the Exchange Agent and will cause the Exchange Agent to forward payment to the holders of fractional interests in accordance with the terms of this Agreement. The Exchange Agent shall, subject to any applicable abandoned property or similar law, until one year after the Effective Date, pay to such holders the cash value of such fraction so determined, without interest. Any balance of such cash, as to which certificates representing Santa Fe Snyder Common Stock outstanding immediately prior to the Effective Time shall not have been surrendered by the expiration of such one-year period, shall thereafter be returned to and held by Devon subject to any applicable statute of limitations or any abandoned property, escheat or similar law. 6 (f) Any portion of the Exchange Fund (including the proceeds of any investments thereof and any shares of Devon Common Stock) that remains unclaimed by the former stockholders of Santa Fe Snyder one year after the Effective Time shall be delivered to Devon. Any former stockholders of Santa Fe Snyder who have not theretofore complied with this Article 3 shall thereafter look only to Devon for payment of their shares of Devon Common Stock, cash in lieu of fractional shares and unpaid dividends and distributions on the Devon Common Stock deliverable in respect of each Certificate such former stockholder holds as determined pursuant to this Agreement. (g) None of Devon, the Exchange Agent or any other person shall be liable to any former holder of shares of Santa Fe Snyder Common Stock for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws. (h) If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Devon, the posting by such person of a bond in such reasonable amount as Devon may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the shares of Devon Common Stock and cash in lieu of fractional shares, and unpaid dividends and distributions on shares of Devon Common Stock deliverable in respect thereof pursuant to this Agreement. Section 3.4 ADJUSTMENT OF EXCHANGE RATIO. If, subsequent to the date of this Agreement but prior to the Effective Time, Santa Fe Snyder changes the number of shares of Santa Fe Snyder Common Stock, or Devon changes the number of shares of Devon Common Stock, issued and outstanding as a result of a stock split, reverse stock split, stock dividend, recapitalization or other similar transaction, the Santa Fe Snyder Exchange Ratio and other items dependent thereon shall be appropriately adjusted. Section 3.5 RULE 16b-3 APPROVAL. Devon agrees that the Devon Board of Directors or the Compensation Committee of the Devon Board of Directors shall, at or prior to the Effective Time, adopt resolutions specifically approving, for purposes of Rule 16b-3 ("Rule 16b-3") under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), the receipt, pursuant to Section 3.2, of Devon Common Stock and Devon stock options by officers and directors of Santa Fe Snyder who will become officers or directors of the Devon subject to Section 16 of the Exchange Act. ARTICLE 4 REPRESENTATIONS AND WARRANTIES OF SANTA FE SNYDER Except as set forth in the disclosure letter delivered to Devon concurrently with the execution hereof (the "Santa Fe Snyder Disclosure Letter") or as disclosed with reasonable specificity in the Santa Fe Snyder Reports (as defined in Section 4.7), Santa Fe Snyder represents and warrants to Devon that: 7 Section 4.1 EXISTENCE; GOOD STANDING; CORPORATE AUTHORITY. Santa Fe Snyder is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware. Santa Fe Snyder is duly qualified to do business as a foreign corporation and is in good standing under the laws of any jurisdiction in which the character of the properties owned or leased by it therein or in which the transaction of its business makes such qualification necessary, except where the failure to be so qualified would not have, individually or in the aggregate, a Santa Fe Snyder Material Adverse Effect (as defined in Section 9.9). Santa Fe Snyder has all requisite corporate power and authority to own, operate and lease its properties and to carry on its business as now conducted. The copies of Santa Fe Snyder's certificate of incorporation and bylaws previously made available to Devon are true and correct and contain all amendments as of the date hereof. Section 4.2 AUTHORIZATION, VALIDITY AND EFFECT OF AGREEMENTS. Santa Fe Snyder has the requisite corporate power and authority to execute and deliver this Agreement, the Stock Option Agreements and all other agreements and documents contemplated hereby, to which it is a party. The consummation by Santa Fe Snyder of the transactions contemplated hereby and by the Stock Option Agreements has been duly authorized by all requisite corporate action, other than, with respect to the Merger, the approval and adoption of this Agreement by Santa Fe Snyder's stockholders. This Agreement and the Stock Option Agreements constitute the valid and legally binding obligations of Santa Fe Snyder to the extent it is a party, enforceable in accordance with their respective terms, subject to applicable bankruptcy, insolvency, moratorium or other similar laws relating to creditors' rights and general principles of equity. Section 4.3 CAPITALIZATION. The authorized capital stock of Santa Fe Snyder consists of 300,000,000 shares of Santa Fe Snyder Common Stock, and 50,000,000 shares of Santa Fe Snyder preferred stock, par value $0.01 per share ("Santa Fe Snyder Preferred Stock"). As of May 24, 2000, there were (a) 183,035,836 shares of Santa Fe Snyder Common Stock issued and outstanding (including 40,000 shares of restricted stock to be granted to non-employee directors, 20,000 shares of bonus stock to be granted to the non-employee directors and 345,324 shares of restricted stock to be granted to James L. Payne, all such shares to be issued as of May 16, 2000) and (b) no shares of Santa Fe Snyder Preferred Stock issued and outstanding. All issued and outstanding shares of Santa Fe Snyder Common Stock (i) are duly authorized, validly issued, fully paid, nonassessable and free of preemptive rights, (ii) were not issued in violation of the terms of any agreement or other understanding binding upon Santa Fe Snyder and (iii) were issued in compliance with all applicable charter documents of Santa Fe Snyder and all applicable federal and state securities laws, rules and regulations. As of the date of this Agreement, except as set forth in this Section 4.3 or in the Stock Option Agreements and except for any shares of Santa Fe Snyder Common Stock issued pursuant to the plans described in the Santa Fe Snyder Disclosure Letter, there are no outstanding shares of capital stock and there are no options, warrants, calls, subscriptions, convertible securities, or other rights, agreements or commitments which obligate Santa Fe Snyder or any of its Subsidiaries to issue, transfer or sell any shares of capital stock or other voting securities of Santa Fe Snyder or any of its Subsidiaries. Santa Fe Snyder has no outstanding bonds, debentures, notes or other obligations the holders of which have the right to vote (or which are convertible into or exercisable for securities having the right to vote) with the stockholders of Santa Fe Snyder on any matter. 8 Section 4.4 SIGNIFICANT SUBSIDIARIES. For purposes of this Agreement, "Significant Subsidiary" shall mean significant subsidiary as defined in Rule 1-02 of Regulation S-X of the Exchange Act. Each of Santa Fe Snyder's Significant Subsidiaries is a corporation or partnership duly organized, validly existing and in good standing (where applicable) under the laws of its jurisdiction of incorporation or organization, has the corporate or partnership power and authority to own, operate and lease its properties and to carry on its business as it is now being conducted, and is duly qualified to do business and is in good standing (where applicable) in each jurisdiction in which the ownership, operation or lease of its property or the conduct of its business requires such qualification, except for jurisdictions in which such failure to be so qualified or to be in good standing would not have, individually or in the aggregate, a Santa Fe Snyder Material Adverse Effect. All of the outstanding shares of capital stock of, or other ownership interests in, each of Santa Fe Snyder's Significant Subsidiaries is duly authorized, validly issued, fully paid and nonassessable, and is owned, directly or indirectly, by Santa Fe Snyder free and clear of all liens, pledges, security interests, claims, preferential purchase rights or other rights, interests or encumbrances ("Liens"). Schedule 4.4 to the Santa Fe Snyder Disclosure Letter sets forth for each Significant Subsidiary of Santa Fe Snyder, its name and jurisdiction of incorporation or organization. Section 4.5 NO VIOLATION. Neither Santa Fe Snyder nor any of its Subsidiaries is, or has received notice that it would be with the passage of time, in violation of any term, condition or provision of (a) its charter documents or bylaws, (b) any loan or credit agreement, note, bond, mortgage, indenture, contract, agreement, lease, license or other instrument or (c) any order of any court, governmental authority or arbitration board or tribunal, or any law, ordinance, governmental rule or regulation to which Santa Fe Snyder or any of its Subsidiaries or any of their respective properties or assets is subject, or is delinquent with respect to any report required to be filed with any governmental entity, except, in the case of matters described in clause (b) or (c), as would not have, individually or in the aggregate, a Santa Fe Snyder Material Adverse Effect. Santa Fe Snyder and its Subsidiaries hold all permits, licenses, variances, exemptions, orders, franchises and approvals of all governmental authorities necessary for the lawful conduct of their respective businesses (the "Santa Fe Snyder Permits"), except where the failure so to hold would not have, individually or in the aggregate, a Santa Fe Snyder Material Adverse Effect. Santa Fe Snyder and its Subsidiaries are in compliance with the terms of the Santa Fe Snyder Permits, except where the failure so to comply would not have, individually or in the aggregate, a Santa Fe Snyder Material Adverse Effect.

(a) Neither the execution and delivery by Devon and Merger Co. of this Agreement, the execution and delivery by Devon of the Stock Option Agreements nor the consummation by Devon and Merger Co. of the transactions contemplated hereby or thereby in accordance with the terms hereof or thereof will: (i) conflict with or result in a breach of any provisions of the charter documents or bylaws of Devon or Merger Co.; (ii) violate, or conflict 19 with, or result in a breach of any provision of, or constitute a default (or an event which, with notice or lapse of time or both, would constitute a default) under, or result in the termination or in a right of termination or cancellation of, or give rise to a right of purchase under, or accelerate the performance required by, or result in the creation of any Lien upon any of the properties of Devon or its Subsidiaries under, or result in being declared void, voidable, or without further binding effect, or otherwise result in a detriment to Devon or any of its Subsidiaries under any of the terms, conditions or provisions of, any note, bond, mortgage, indenture, deed of trust, license, franchise, permit, lease, contract, agreement, joint venture or other instrument or obligation to which Devon or any of its Subsidiaries is a party, or by which Devon or any of its Subsidiaries or any of their properties is bound or affected; or (iii) contravene or conflict with or constitute a violation of any provision of any law, rule, regulation, judgment, order or decree binding upon or applicable to Devon or any of its Subsidiaries, except, in the case of matters described in clause (ii) or (iii), as would not have, individually or in the aggregate, a Devon Material Adverse Effect.

(d) Neither the execution and delivery of this Agreement nor the consummation of the transactions contemplated hereby will: (i) result in any payment from Devon or its Subsidiaries (including severance, unemployment compensation, parachute payment, bonus or otherwise) becoming due to any director, employee or independent contractor of Devon or any of its Subsidiaries under any Devon Plan (as defined in Section 5.11) or otherwise; (ii) materially increase any benefits otherwise payable under any Devon Plan or otherwise; or (iii) result in the acceleration of the time of payment or vesting of any such benefits. Section 5.7 SEC DOCUMENTS. Devon has made available to Santa Fe Snyder each registration statement, report, proxy statement or information statement (other than preliminary materials) filed by Devon with the SEC since January 1, 1999, each in the form (including exhibits and any amendments thereto) filed with the SEC prior to the date hereof (collectively, the "Devon Reports"), and Devon has filed all forms, reports and documents required to be filed 20 by it with the SEC pursuant to relevant securities statutes, regulations, policies and rules since such time. As of their respective dates, the Devon Reports (i) were prepared in all material respects in accordance with the applicable requirements of the Securities Act, the Exchange Act, and the rules and regulations thereunder and complied in all material respects with the then applicable accounting requirements and (ii) did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements made therein, in the light of the circumstances under which they were made, not misleading except for such statements, if any, as have been modified by subsequent filings with the SEC prior to the date hereof. Each of the consolidated balance sheets included in or incorporated by reference into the Devon Reports (including the related notes and schedules) fairly presents in all material respects the consolidated financial position of Devon and its Subsidiaries as of its date and each of the consolidated statements of operations, cash flows and stockholders' equity included in or incorporated by reference into the Devon Reports (including any related notes and schedules) fairly presents in all material respects the results of operations, cash flows or changes in stockholders' equity, as the case may be, of Devon and its Subsidiaries for the periods set forth therein (subject, in the case of unaudited statements, to such exceptions as may be permitted by Form 10-Q of the SEC), in each case in accordance with generally accepted accounting principles consistently applied during the periods involved, except as may be noted therein. Since December 31, 1999, neither Devon nor any of its Subsidiaries had any liabilities or obligations of any nature (whether accrued, absolute, contingent or otherwise), other than liabilities or obligations disclosed in the Devon Reports or which would not have, individually or in the aggregate, a Devon Material Adverse Effect. Section 5.8 LITIGATION. There are no actions, suits or proceedings pending against Devon or any of its Subsidiaries or, to Devon's knowledge, threatened against Devon or any of its Subsidiaries, at law or in equity, or before or by any federal, state or foreign commission, board, bureau, agency or instrumentality, that are likely to have, individually or in the aggregate, a Devon Material Adverse Effect. There are no outstanding judgments, decrees, injunctions, awards or orders against Devon or any of its Subsidiaries that are likely to have, individually or in the aggregate, a Devon Material Adverse Effect. Section 5.9 ABSENCE OF CERTAIN CHANGES. Since December 31, 1999, there has not been (i) an event that would have a Devon Material Adverse Effect; (ii) any material change by Devon or any of its Subsidiaries, when taken as a whole, in any of its accounting methods, principles or practices or any of its tax methods, practices or elections; (iii) any material damage, destruction, or loss to the business or properties of Devon and its Subsidiaries, taken as a whole, not covered by insurance; (iv) any declaration, setting aside or payment of any dividend or other distribution in respect of the capital stock of Devon, or any direct or indirect redemption, purchase or any other acquisition by Devon of any such stock (except for, and provided that, Devon may continue to pay or cause to be paid, dividends upon the shares of Devon Common Stock and the Northstar Exchangeable Shares at a rate not greater than $.05 per share in any quarter); (v) any change in the capital stock or in the number of shares or classes of Devon's authorized or outstanding capital stock (other than as a result of exercises of options to purchase Devon Common Stock outstanding or issued as permitted hereunder); (vi) any increase in or establishment of any bonus, insurance, severance, deferred compensation, pension, retirement, profit sharing, stock option, stock purchase or other employee benefit plan, except in the ordinary course of business; or (vii) any other event or condition known to Devon particularly 21 pertaining to and adversely affecting the operations, assets or business of Devon or any of its Subsidiaries (other than events or conditions which are of a general or industry-wide nature and of general public knowledge) which would constitute, individually or in the aggregate, a Devon Material Adverse Effect. Section 5.10 TAXES. (a) Each of Devon, its Subsidiaries and each affiliated, consolidated, combined, unitary or similar group of which any such corporation is or was a member has (i) duly filed (or there has been filed on its behalf) on a timely basis (taking into account any extensions of time to file before the date hereof) with appropriate governmental authorities all Returns required to be filed by or with respect to it, except to the extent that any failure to file would not have, individually or in the aggregate, a Devon Material Adverse Effect, and (ii) duly paid or deposited in full on a timely basis or made adequate provisions in accordance with generally accepted accounting principles (or there has been paid or deposited or adequate provision has been made on its behalf) for the payment of all taxes required to be paid by it other than those being contested in good faith by Devon or a Subsidiary of Devon and except to the extent that any failure to pay or deposit or make adequate provision for the payment of such taxes would not have, individually or in the aggregate, a Devon Material Adverse Effect.

(b) Neither Devon nor any of its Subsidiaries is subject to a dispute, strike or work stoppage with respect to any collective bargaining agreement, contract or other agreement or understanding with a labor union or labor organization to which it is a party or by which it is bound which would have, individually or in the aggregate, a Devon Material Adverse Effect. (c) To Devon's knowledge, there are no organizational efforts with respect to the formation of a collective bargaining unit presently being made or threatened involving employees of Devon or any of its Subsidiaries, except for those the formation of which would not have, individually or in the aggregate, a Devon Material Adverse Effect. 23 Section 5.13 ENVIRONMENTAL MATTERS. Except as would not have, individually or in the aggregate, a Devon Material Adverse Effect: (a) there are not any present or, to the knowledge of Devon, past conditions or circumstances that interfere with the conduct of the business of Devon and each of its Subsidiaries in the manner now conducted or which interfere with compliance with any order of any court, governmental authority or arbitration board or tribunal, or any Environmental Law; (b) there are not any present or, to the knowledge of Devon, past conditions or circumstances at, or arising out of, any current or, to the knowledge of Devon, former businesses, assets or properties of Devon or any Subsidiary of Devon, including but not limited to, on-site or off-site disposal or release of any chemical substance, product or waste, which constitute a violation under any Environmental Law or could reasonably be expected to give rise to: (i) liabilities or obligations for any cleanup, remediation, disposal or corrective action under any Environmental Law or (ii) claims arising for personal injury, property damage, or damage to natural resources; (c) neither Devon nor any of its Subsidiaries has (i) received any written notice of noncompliance with, violation of, or liability or potential liability under any Environmental Law, (ii) received any written notice regarding any existing, pending or threatened investigation or inquiry related to alleged violations under any Environmental Laws or regarding any claims for remedial obligations or contribution under any Environmental Laws or (iii) entered into any consent decree or order or is subject to any order of any court or governmental authority or tribunal under any Environmental Law or relating to the cleanup of any hazardous materials contamination; (d) Devon and its Subsidiaries have in full force and effect all material environmental permits, licenses, approvals and other authorizations required to conduct their operations and are operating in material compliance thereunder; and (e) Devon does not know of any reason that would preclude it from renewing or obtaining a reissuance of the material permits, licenses or other authorizations required pursuant to any applicable Environmental Laws to operate and use any of Devon's or its Subsidiaries' assets for their current purposes and uses. Section 5.14 INTELLECTUAL PROPERTY. Devon and its Subsidiaries own or possess adequate licenses or other valid rights to use all patents, patent rights, trademarks, trademark rights and proprietary information used or held for use in connection with their respective businesses as currently being conducted, free and clear of material Liens, except where the failure to own or possess such licenses and other rights would not have, individually or in the aggregate, a Devon Material Adverse Effect, and there are no assertions or claims challenging the validity of any of the foregoing which are likely to have, individually or in the aggregate, a Devon Material Adverse Effect. Except in the ordinary course of business, neither Devon nor any of its Subsidiaries has granted to any other person any license to use any of the foregoing. The conduct of Devon's and its Subsidiaries' respective businesses as currently conducted does not conflict with any patents, patent rights, licenses, trademarks, trademark rights, trade names, trade name rights or copyrights of others in any way likely to have, individually or in the aggregate, a 24 Devon Material Adverse Effect. There is no material infringement of any proprietary right owned by or licensed by or to Devon or any of its Subsidiaries which is likely to have, individually or in the aggregate, a Devon Material Adverse Effect. Section 5.15 TITLE TO PROPERTIES. Except for goods and other property sold, used or otherwise disposed of since December 31, 1999 in the ordinary course of business for fair value, Devon has defensible title for oil and gas purposes to all its properties, interests in properties and assets, real and personal, reflected in its December 31, 1999 financial statements, free and clear of any Lien, except: (a) Liens reflected in the balance sheet of Devon as of December 31, 1999; (b) Liens for current taxes not yet due and payable and (c) such imperfections of title, easements and Liens as would not have, individually or in the aggregate, a Devon Material Adverse Effect. All leases and other agreements pursuant to which Devon or any of its Subsidiaries leases or otherwise acquires or obtains operating rights affecting any real or personal property are in good standing, valid, and effective; and there is not, under any such leases, any existing or prospective default or event of default or event which, with notice or lapse of time, or both, would constitute a default by Devon or any of its Subsidiaries which, individually or in the aggregate, would have a Devon Material Adverse Effect and in respect to which Devon or any of its Subsidiaries has not taken adequate steps to prevent a default from occurring. All major items of operating equipment of Devon and its Subsidiaries are in good operating condition and in a state of reasonable maintenance and repair, ordinary wear and tear excepted. Without limiting the generality of the foregoing, Devon's interest in production of hydrocarbons from each well, unit or property described in the reports of (i) LaRoche Petroleum Consultants, Ltd. dated January 25, 2000, (ii) Paddock Lindstrom & Associates, Ltd. dated January 19, 2000, (iii) Ryder Scott Company dated February 18, 2000 and (iv) Devon dated January 4, 2000 and delivered to Santa Fe Snyder (after deducting all applicable royalties, overriding royalties and other payments out of production) is not materially less than the interest shown under the heading "Net Revenue Interest" for such well, unit or property, and Devon's share of exploration, development and operation costs for each such well, unit or property is not materially greater than the percentage shown under the heading "Working Interest" for such well, unit or property. Devon has not received any material advance, take-or-pay or other similar payments that entitle purchasers of production to receive deliveries of hydrocarbons without paying therefor, and, on a net, company-wide basis, Devon is neither underproduced nor overproduced under gas balancing or similar arrangements. Section 5.16 INSURANCE. Devon and its Subsidiaries maintain insurance coverage reasonably adequate for the operation of their respective businesses (taking into account the cost and availability of such insurance). Section 5.17 NO BROKERS. Devon has not entered into any contract, arrangement or understanding with any person or firm which may result in the obligation of Devon, Merger Co. or Santa Fe Snyder to pay any finder's fees, brokerage or agent's commissions or other like payments in connection with the negotiations leading to this Agreement or the consummation of the transactions contemplated hereby, except that Devon has retained Morgan Stanley Dean Witter to prepare the opinion as set forth in Section 5.18, the arrangements with which have been disclosed in writing to Santa Fe Snyder prior to the date hereof. 25 Section 5.18 OPINION OF FINANCIAL ADVISOR. The Board of Directors of Devon has received the opinion of Morgan Stanley & Co. Incorporated to the effect that, as of the date of this Agreement, the Santa Fe Snyder Exchange Ratio is fair, from a financial point of view, to Devon; it being understood and acknowledged by Santa Fe Snyder that such opinion has been rendered for the benefit of the Board of Directors of Devon, and is not intended to, and may not, be relied upon by Santa Fe Snyder, its affiliates or their respective Subsidiaries. Section 5.19 SANTA FE SNYDER STOCK OWNERSHIP. Neither Devon nor any of its Subsidiaries owns any shares of capital stock of Santa Fe Snyder or any other securities convertible into or otherwise exercisable to acquire capital stock of Santa Fe Snyder. Section 5.20 ACCOUNTING AND REORGANIZATION MATTERS. Each of Devon and Merger Co. intends that the Merger be accounted for as a Pooling of Interests. To the best of its knowledge, neither Devon nor any of its affiliates has taken or agreed to take any action that would prevent the Merger from qualifying (i) for Pooling of Interests accounting treatment or (ii) as a 368(a) Reorganization. Section 5.21 VOTE REQUIRED. The affirmative vote of the holders of a majority of the outstanding shares of Devon Common Stock and the outstanding Northstar Exchangeable Shares, voting as a single class with the Devon Special Voting Share voting for the Northstar Exchangeable Shares as provided in Devon's charter, represented in person or by proxy at a meeting at which quorum is present is the only vote of the holders of any class or series of Devon capital stock necessary to approve this Agreement and the transactions contemplated hereby; PROVIDED, HOWEVER, if a proposal to amend Devon's Certificate of Incorporation is presented at the meeting for approval pursuant to Section 2.1 hereof, the affirmative vote of the holders of a majority of the outstanding shares of Devon Common Stock and the outstanding Northstar Exchangeable Shares, voting as a single class with the Devon Special Voting Share voting for the Northstar Exchangeable Shares as provided in Devon's charter, will be required for approval. Section 5.22 DEVON RIGHTS AGREEMENT. Devon has taken all required action under the Devon Rights Agreement so that none of the execution and delivery of this Agreement or the Stock Option Agreements, the issuance of shares of Devon Common Stock upon exercise of the option granted to Santa Fe Snyder pursuant to the applicable Stock Option Agreement, and the consummation of the Merger or any other transaction contemplated hereby or by the Stock Option Agreement, will cause (i) the Devon Rights to become exercisable under the Devon Rights Agreement, (ii) Santa Fe Snyder or any of its Subsidiaries to be deemed an "Acquiring Person" (as defined in the Devon Rights Agreement), (iii) any such event to be an event described in Section 7(e) or 13 of the Devon Rights Agreement or (iv) the "Stock Acquisition Date" or the "Distribution Date" (each as defined in the Devon Rights Agreement) to occur upon any such event. Devon has delivered to Santa Fe Snyder a true and complete copy of the Devon Rights Agreement, as amended to date. Section 5.23 CERTAIN APPROVALS. Devon's Board of Directors has taken any and all necessary and appropriate action to render inapplicable to the Merger and the transactions contemplated by this Agreement and the Stock Option Agreements the provisions of Section 203 of the DGCL. 26 Section 5.24 CERTAIN CONTRACTS. Neither Devon nor any of its Subsidiaries is a party to or bound by (i) any non-competition agreement or any other agreement or obligation which purports to limit the manner in which, or the localities in which, the current business of Devon and its Subsidiaries, taken as a whole, or Santa Fe Snyder and its Subsidiaries, taken as a whole, is conducted or (ii) any executory agreement or obligation which pertains to the acquisition or disposition of any asset, or which provides any third party any lien, claim or preferential right with regard thereto, except in each case for any such agreements or obligations which would not have, individually or in the aggregate, a Devon Material Adverse Effect.
