                                   RECITALS

        Since February 23, 1987, Morgenthaler has served Apache with diligence

                                  AGREEMENT

        For good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, Apache and Morgenthaler agree as follows:

        (1)     Resignation.  Effective 6:00 p.m. CST, November 10, 1993, 
                Morgenthaler's employment with Apache terminated and, as a 
                result, Morgenthaler resigns all positions as a director, 
                officer and committee member of Apache, its subsidiaries and 
                affiliated entities.            

        (2)     Temporary Employment.  From 7:00 a.m. CST, November 11, 1993, 
                through   6:00 p.m. CST, December 15, 1993 (the "Temporary 
                Employment Period"), Apache employs Morgenthaler as a 
                temporary employee at the pay rate of $17,083.33 per month 
                (pro-rated by the day).                           

        (3)     Consulting.  Apache engages Morgenthaler to render consulting 
                services  to Apache and its subsidiaries for a period 
                commencing December 16, 1993, and continuing through 
                December 15, 1995 (subject to early terminated as stated in 
                the next sentence, the "Consulting Period"). If Apache does 
                not pay 1993 incentive compensation bonuses to its executives 
                or provide for other additional compensation recognizing 1993 
                executive performance, then the Consulting Period shall 
                terminate  on August 15, 1995.
   2
(4)     Services.  During the Temporary Employment Period and the Consulting
        Period, Morgenthaler shall perform such consulting services as are
        reasonably requested by the Chief Executive Officer of Apache (the
        "CEO") and as are not inconsistent with Morgenthaler's prior duties and
        responsibilities as an officer of Apache.  Morgenthaler shall not be
        required to maintain any office hours, nor shall Morgenthaler be
        present at the offices of Apache except upon request of the CEO.

(5)     Other Activities.  Morgenthaler's obligation to render consulting
        services shall be subordinate to, and shall be rendered only to the
        extent there is no interference with, his other business, employment
        and personal activities.  Morgenthaler shall be free to accept
        full-time or part-time employment with any organization, and to engage
        in any business enterprise on his own behalf during the Consulting
        Period or thereafter, whether or not the organization or enterprise
        competes with Apache, so long as Morgenthaler complies with paragraphs
        (6) and (7) of this agreement.  If Morgenthaler desires to accept
        employment with another organization, and if that employment creates a
        professional conflict of interest for Morgenthaler, then Morgenthaler
        shall promptly inform Apache's CEO of that employment and Morgenthaler
        shall be automatically released from all obligations under paragraphs
        (3) and (4) of this agreement, but all other terms of this agreement,
        including those relating to payments and benefits to Morgenthaler,
        shall remain in effect.

(6)     Goodwill.  Morgenthaler shall generally foster, maintain and promote
        the goodwill of Apache, its subsidiaries, affiliates, and their
        respective directors, officers, employees and/or representatives, past
        and present.  Apache shall generally foster, maintain and promote the
        reputation and image of Morgenthaler.  Apache shall not hinder or
        discourage the future employment of Morgenthaler.

(7)     Confidentiality.  In addition to his fiduciary responsibilities and his
        responsibilities as an Officer and General Counsel of Apache and his
        responsibilities under the Texas Disciplinary rules of Professional
        Conduct not to disclose certain information of or relating to Apache,
        Morgenthaler shall maintain the confidentiality of, and shall not
        disclose, Apache's business dealings, trade secrets, supplier lists,
        customer lists, properties, geographic or financial areas of interest,
        exploration plans or techniques or any other confidential information
        of or relating to Apache, its subsidiaries, affiliates and their
        directors, officers, employees and/or representatives, past and
        present, and Morgenthaler shall not use such information in any manner,
        whether for his own benefit or for the benefit of any other person or
        entity, or to the detriment of Apache, its subsidiaries, affiliates and
        their directors, officers, employees and/or representatives, past and
        present or otherwise.




                                      2
   3
(8)     Monthly Payments.  On or before the 16th day of each calendar          
        month during the Consulting Period (commencing with December           
        16, 1993), Morgenthaler shall invoice Apache for services in           
        the amount of $17,083.33, and Apache shall pay Morgenthaler            
        the invoiced amount on or before the first day of the next             
        calendar month.  The invoiced amounts shall continue to be             
        paid without regard to Morgenthaler's employment by another            
        organization, his participation in a partnership, or his               
        engagement in business for his own account.  The invoiced              
        amounts shall continue to be paid if Morgenthaler is disabled,         
        and shall continue to be paid to Morgenthaler's estate, heirs,         
        and successors in the event of his death.  The invoiced                
        amounts shall continue to be paid if Morgenthaler is released          
        from his obligations under paragraphs (3) and (4) of this              
        agreement. Failure or tardiness by Morgenthaler in invoicing           
        Apache shall not waive or release Morgenthaler's right to              
        payment, but amounts invoiced more than five business days             
        late by Morgenthaler shall not be due until ten business days          
        after invoice.  Morgenthaler may invoice Apache for the                
        initial monthly payment prior to inception of the Consulting           
        Period.                                                                
         
(9)     Expense Reimbursement.  Subject to Apache's travel policies governing
        its executives, Apache shall reimburse Morgenthaler for all travel,
        airline, room, entertainment, meal, beverage, car rental and other
        out-of-pocket expenses incurred by Morgenthaler in the course of
        performing his consulting obligations under this agreement, provided
        that such consulting expenses are approved in advance by Apache.

(10)    Benefits.  During the Temporary Employment Period, Morgenthaler shall
        receive the same benefits as Apache provides its executive officers.
        During the Consulting Period, Apache shall:

        (a)      provide medical, dental and vision benefits to Morgenthaler
                 and his dependents to the same extent, and subject to the same
                 premium co-payments, as are extended to Apache executives; and

        (b)      provide life insurance and disability benefits (including
                 supplemental group life insurance) to Morgenthaler to the same
                 extent as extended to Apache executives;

        but the foregoing benefits shall terminate to the extent that
        replacement benefits are offered by an employer with which Morgenthaler
        accepts employment.  Apache shall not impair the cash value of any life
        insurance currently maintained by Apache for Morgenthaler, and that
        cash value shall remain the property of Morgenthaler.  Apache shall
        cause its employees, insurance carriers and agents to cooperate fully
        with Morgenthaler in managing and maintaining Morgenthaler's insurance
        coverage, in responding to Morgenthaler's insurance claims and in
        responding to Morgenthaler's inquiries concerning insurance coverages.





                                       3
   4
(11)    Plan Balances.  Apache shall cooperate in the prompt rollover of
        Morgenthaler's 401(k) account balances to an IRA account or other
        account designated by Morgenthaler.  On January 3, 1994, Apache shall
        disburse to Morgenthaler, or direct the disbursement to Morgenthaler
        of, the balance in Morgenthaler's non-qualified retirement plan
        account.

(12)    Options and Phantoms.  Except as provided in this paragraph,
        Morgenthaler's outstanding stock options and phantom stock units shall
        be governed by the terms of the Apache Corporation 1990 Stock Incentive
        Plan and the 1990 Phantom Stock Appreciation Plan (the "Phantom Plan")
        and the stock option agreements entered into between Morgenthaler and
        Apache.  On January 3, 1994, Apache shall pay Morgenthaler the sums due
        him under the Phantom Plan as a result of his November 10, 1993,
        Termination of Employment without Disqualification (as defined in the
        Phantom Plan).  Morgenthaler waives his right to payment on or before
        December 10, 1993, under the Phantom Plan.

(13)    Databases.  During the Consulting Period, Morgenthaler shall continue
        to have free access to and reasonable use of the business and legal
        databases now maintained by Apache and used by Morgenthaler as an
        executive of Apache.

(14)    Office Equipment.  Apache shall, on December 16, 1993, and in exchange
        for the payment of $2,000.00 to Apache by Morgenthaler, sell and convey
        to Morgenthaler the office equipment now in Morgenthaler's possession,
        being one cellular telephone, one telefax, one personal computer,
        software and one printer.

(15)    Consulting Payment.  On January 3, 1994, Apache shall pay Morgenthaler
        $352,000.00 as a non-refundable consulting payment.

(16)    Financing Planning.  Apache shall pay or reimburse Morgenthaler for
        personal tax and financial planning by Arthur Andersen & Co. during the
        Consulting Period as required to evaluate and plan the financial and
        tax impact of this agreement and termination of his employment and as
        required to prepare tax returns for 1993 and 1994.

(17)    Independent Contractor and Taxes.  Morgenthaler acknowledges that his
        engagement under this agreement is as an independent contractor and not
        as an employee of Apache or its subsidiaries or affiliates.
        Accordingly, Morgenthaler will be responsible for the payment of all
        income tax and other taxes on cash amounts payable to Morgenthaler, and
        Apache will not withhold any amounts from payments made under this
        agreement.  If the Internal Revenue Service asserts that Apache should
        have withheld federal income taxes and/or Morgenthaler's share of FICA
        taxes from such payments, Morgenthaler will reimburse Apache for any
        monies paid by Apache to the U.S. Government in compliance with such
        assertion, except for payments of interest or penalties.





                                       4
   5
(18)    Releases.  Morgenthaler releases Apache and each of its subsidiaries,
        affiliates and their respective directors, officers, employees and/or
        representatives, past and present (hereafter the "Company"), and the
        Company releases Morgenthaler, from any and all rights and claims
        arising in any way out of Morgenthaler's employment or the acts or
        omissions of the Company or Morgenthaler which occurred during the term
        of Morgenthaler's employment, or arose out of the termination of
        Morgenthaler's employment.  The Company and Morgenthaler further
        release and hold harmless each other from and against any and all
        claims against the other that they may have based on any negligent or
        intentional acts or omissions of any character whatsoever, whether
        related to Morgenthaler's employment or otherwise, including without
        limitation statements made by, to or about Morgenthaler or the Company,
        which occurred prior to the effective date of this agreement, whether
        known or unknown by the Company or Morgenthaler.  The foregoing release
        includes without limitation any rights and claims under state, federal,
        or local laws, including without limitation, the Age Discrimination in
        Employment Act, the Texas Commission on Human Rights Act and the common
        law of the states of Texas, Colorado and any other jurisdiction.
        Morgenthaler and the Company further agree that they will not institute
        any charge, complaint or litigation against the other based on such
        released rights and/or claims.  Apache indemnifies and holds harmless,
        and agrees to indemnify and hold harmless, Morgenthaler against any
        liability or expense, including attorneys' fees and costs, incurred by
        Morgenthaler in evaluating, defending, compromising, settling or
        satisfying any claim (excluding those actions determined to be
        violative of applicable criminal laws) brought by any person or
        organization that is included within the definition of Company but that
        is not a signatory to this agreement.  Notwithstanding the foregoing,
        the releases contained herein shall not apply to any rights that
        Morgenthaler may have under:

        (a)      Apache's 1990 Stock Incentive Plan and the Phantom Plan and
                 the option agreements issued under those plans to which
                 Morgenthaler is a party;

        (b)      Apache's 401(k) plan and non-qualified retirement plan;

        (c)      this agreement; or

(19)    Non-Assignability.  Neither this agreement nor any right or interest
        herein may be assigned or transferred by Apache or Morgenthaler without
        the other's written consent, except as to:

        (a)      the rights of Morgenthaler's estate, heirs and devisees to
                 certain benefits under this agreement; and

                assets, or the merger or combination of Apache with
                another organization, if the asset purchaser or
                surviving organization assumes the full performance of
                Apache's obligations under this agreement, but Apache
                shall not be relieved of its obligations under this
                agreement by that assumption.

(20)    No Attachment.  Except as required by law, Morgenthaler's right to
        receive payments under this agreement shall not be subject to
        anticipation, commutation, alienation, sale, encumbrance, pledge,
        hypothecation, execution, attachment, levy, offset, deduction, setoff,
        condition, or assignment by operation of law, and any attempt,
        voluntary or involuntary, to effect such action shall be null and void.

        Morgenthaler, Apache and its subsidiaries and affiliates and their
        permitted successors and assigns.

(22)    Amendment, Modification, Waiver.  This agreement shall not be amended
        or modified except by an instrument in writing signed by the parties
        hereto.  No term of this agreement shall be deemed to have been waived,
        nor shall there be an estoppel against enforcement of any provision of
        this agreement, except by written instrument of the party charged with
        such waiver or estoppel.  No person or organization, including those
        within the definition of Company, not a party to this agreement or a
        permitted successor to a party to this agreement, shall be a
        third-party beneficiary of this agreement or entitled to enforce its
        terms.  Morgenthaler acknowledges that he has had at least 21 days to
        consider this agreement and has had legal advice with respect thereto.

(23)    Remedies.  Upon any material breach of this agreement by a party, the
        other party shall be entitled to seek damages for the breach, and/or
        shall be entitled to seek specific performance of this agreement.
        Morgenthaler and Apache acknowledge and confess that there is no
        adequate remedy at law for breach of obligations in this agreement
        other than obligations for the payment of money.  The prevailing party
        in any litigation shall be entitled to an award of attorneys' fees by
        the court.  Interest on sums due from one party to another shall bear
        interest at 18 percent per annum until paid.

        employees or consultants.
