4.       Effective as of November 16, 1989, Section 3.01(b) shall be replaced
in its entirety by the following:

         "(b)    The amount of a Participant's Deferred Contributions made
                 pursuant to the Plan shall equal the amount of Participant
                 Before-Tax Contributions that would have been credited to the
                 Participant's Before-Tax Contributions Account pursuant to
                 Section 3.2 of the Retirement/Savings Plan but could not be so
                 credited due to restrictions imposed by the Code, including
                 without limitation restrictions under Section 401(a)(17),
                 401(k)(3), 401(m), 402(g),





                                       2
   3
                 and 415(c).  The amount of a Participant's Deferred
                 Contribution shall be determined by reference to the
                 Participant's elected Before-Tax Contribution percentage under
                 the Retirement/Savings Plan as of the first day of the Plan
                 Year or, if the Participant was not eligible to participate in
                 this Plan on such date, as of the first day on which the      
                 Participant is eligible to participate in this Plan, without 
                 regard to any change in the Participant's Before-Tax 
                 Contribution percentage under the Retirement/Savings Plan 
                 which subsequently becomes effective in such Plan Year.  An 
                 election to participate in this Plan for any Plan Year shall 
                 be irrevocable; provided, however, that a Participant's 
                 Deferred Contributions shall be suspended as specified in 
                 Section 5.04 following a hardship withdrawal from this Plan 
                 and shall also be suspended, for the number of months required
                 by Section 7.1 of the Retirement/Savings Plan, following a
                 hardship withdrawal from that plan.  Notwithstanding anything 
                 herein to the contrary, a Participant shall not be permitted 
                 to defer compensation which is earned or payable prior to the 
                 execution and delivery of the Participant's enrollment 
                 agreement."
        
5.       Effective as of November 16, 1989, Section 3.02 shall be amended by
changing both occurrences of "Section 3.03 of the Retirement/Savings Plan" to
"Section 3.1 of the Retirement/Savings Plan."

6.       Effective as of July 1, 1992, the following new subsection shall be
added to the end of Section 5.01:

         "(f)    All Participants in the Plan who are employed by the Company
                 on July 1, 1992 shall become 100% vested with respect to all
                 Company Deferrals made to the Plan prior to or as of July 1,
                 1992.  If a Participant was not previously 100% vested, then
                 the amount that becomes 100% vested pursuant to this
                 subsection shall be allocated to a special account and a new
                 account shall be established for all Company Deferrals made
                 with respect to such Participant subsequent to July 1, 1992.
                 At such time as any such Participant becomes 100% vested in
                 accordance with the rules of subsection (d) above, the
                 Participant's two separate accounts shall be merged into one
                 account."

7.       Effective as of January 1, 1992, Section 5.04(f) shall be replaced in
its entirety by the following:

         "(f)    The Participant's deferrals shall be suspended for six (6)
                 months following the date of his hardship withdrawal from this
                 Plan.  If a Participant makes a hardship withdrawal from this
                 Plan and also makes a hardship withdrawal from the
                 Retirement/Savings Plan, the suspension period under this Plan
                 shall run concurrently with the suspension period under the
                 Retirement/Savings Plan, if any, and the suspension period
                 under this Plan shall be the longer of the suspension period
                 provided under the Retirement/Savings Plan or the 6-month
                 suspension provided by this Plan."

         and powers necessary for that purpose, including, but not by way of
         limitation, full discretion and power to interpret the Plan, to
         determine the eligibility, status and rights of all persons under the
         Plan and, in general, to decide any dispute."

         by Apache Corporation's board of directors or by an officer of Apache
         Corporation who is authorized by Apache Corporation's board of
         directors to amend the Plan.  Each amendment shall be executed by an
         officer of Apache Corporation to whom Apache Corporation's board of
         directors has delegated the authority to execute the amendment."

10.      Effective as of the date this amendment is executed, Section 9.09
shall be replaced in its entirety by the following:

         "9.09   Governing Law.

                 The Plan shall be construed in accordance with ERISA, the
         Code, and, to the extent applicable, the laws of the State of Texas,
         excluding any conflicts-of-law provisions."



IN WITNESS WHEREOF, this First Amendment has been executed this 24th day of
October, 1995.
