                                   AMENDMENTS
                                     TO THE
               APACHE CORPORATION 401(K) RETIREMENT/SAVINGS PLAN

         THIS AMENDMENT is made this 31st day of December 1993 by Apache
Corporation, a Delaware corporation, to be effective as set forth below.

                                    RECITALS

1.       Apache Corporation maintains the Apache Corporation 401(k)
Retirement/Savings Plan (the "Plan").

2.       Section 10.4 of the Plan provides that Apache Corporation may modify
or amend the Plan at any time in any respect.  Pursuant to that right and power
the Plan is hereby amended as set forth below, effective as of the dates set
forth below.

                                   AMENDMENT

I.       AMENDMENTS RELATING TO ERISA Section  404(C) COMPLIANCE

A.       Effective January 1, 1994, the following definition shall be added to
Article I.

         "Account Owner" means a Participant who has an Account balance, an
         Alternate Payee who has an Account balance, or a beneficiary who has
         obtained an interest in the Account(s) of the previous Account Owner
         because of the previous Account Owner's death.

B.       Effective February 1, 1994, Section 2.3 shall be replaced in its
entirety by the following.

         2.3  Enrollment Procedure.

              Notwithstanding Sections 2.1 and 2.2, a Covered Employee shall
         not be eligible to participate in the Plan until after completing the
         enrollment procedures specified by the Committee.  Such enrollment
         procedures may, for example, require the Covered Employee to complete
         and sign an enrollment form or to complete a voice-response telephone
         enrollment.  The Covered Employee shall provide the initial investment
         direction, the address and date of birth of the Employee, and the
         name, address, and date of birth of each beneficiary of the Employee,
         the initial rate of the Participant Before-Tax Contributions, and any
         other information requested by the Committee.  An election to make
         Participant Before Tax Contributions shall not be effective until
         after the Covered Employee has properly completed the enrollment
         procedures.  The Committee may require that the enrollment procedure
         be completed a certain number of
   2
         days prior to the date that a Covered Employee actually begins to
         participate.

C.       Effective February 1, 1994, Article IX shall be replaced in its
entirety by the following.

                                   ARTICLE IX

                         Trust Agreement - Investments.

         9.1  Trust Agreement.

              Apache has entered into a Trust agreement to provide for the
         holding, investment and administration of the funds of the Plan.  The
         Trust agreement shall be part of the Plan, and the rights and duties
         of any individual under the Plan shall be subject to all terms and
         provisions of the Trust agreement.

         9.2  Expenses of Trust.

                          (a)     Except as provided in Subsection (b) below,
         all taxes upon or in respect of the Trust shall be paid by the Trustee
         out of the Trust assets, and all expenses of administering the Trust
         shall be paid by the Trustee out of the Trust assets, to the extent
         such taxes and expenses are not paid by the Company or the Account
         Owner.  No fiduciary shall receive any compensation for services
         rendered to the Plan if the fiduciary is being compensated on a full
         time basis by the Company.

                          (b)     All expenses of individually directed
         transactions in Trust assets, including without limitation the
         Trustee's transaction fee, brokerage commissions, transfer taxes,
         interest on insurance policy loans, and any taxes and penalties that
         may be imposed as a result of an individual's investment direction
         shall be assessed against the Account(s) of the Account Owner
         directing such transactions.

         9.3  Investments.

                          (a)     Section 404(c) Plan.  The Plan is intended to
         be a plan described in ERISA section 404(c).  To the extent that an
         Account Owner exercises control over the investment of his or her
         Accounts, no person who is a fiduciary shall be liable for any loss,
         or by reason of any breach, that is the direct and necessary result of
         the Account Owner's exercise of control.

                          (b)     Directed Investments.  Accounts shall be 
         invested, upon the written or telephone voice-response





                                     - 2 -
   3
         direction of each Account Owner, in any one or more of a series of
         investment funds designated by the Committee from time to time.  One
         or more such funds may, at the sole discretion of the Committee,
         consist of shares of Company Stock.  If so directed by Account Owners,
         up to 100% of the Accounts under the Plan may be invested in Company
         Stock.  The funds available for investment and the principal features
         thereof, including a general description of the investment objectives,
         the risk and return characteristics, and the type and diversification
         of the investment portfolio of each fund, shall be communicated to the
         Account Owners in the Plan from time to time.  Any changes in such
         funds shall be immediately communicated to all Account Owners.

                          (c)     Absence of Directions.  To the extent that an
         Account Owner fails to affirmatively direct the investment of his or
         her Accounts, the Committee shall direct the Trustee in writing
         concerning the investment of such Accounts.  The Committee shall act
         by majority vote.  Any dissenting member of the Committee shall,
         having registered his or her dissent in writing, thereafter cooperate
         to the extent necessary to implement the decision of the Committee.

                          (d)     Change in Investment Directions.  Account
         Owners may change their investment directions, with respect to
         investment of new contributions and with respect to the investment of
         existing amounts allocated to Accounts, every three months unless the
         Committee determines that more frequent changes in investment
         directions shall be made available with respect to one or more of the
         investment funds.  Such changes shall be effective, prospectively, as
         of the time established by the Committee.  The Committee shall
         establish procedures for giving investment directions, which shall be
         in writing and communicated to Account Owners.  For example, the
         procedures could permit an Account Owner to change the investment
         direction of new contributions as of the first day of every calendar
         quarter, provided that the Committee receives at least two weeks prior
         written notice; the procedures could also permit an Account Owner to
         change the investment direction of existing Account balances once in a
         calendar quarter, on any business day, by giving telephone
         voice-response instructions to the Trustee.

D.       Effective February 1, 1994, Article XIV shall be added to the end of
the Plan.

                                  ARTICLE XIV

                        Matters Affecting Company Stock

         14.1  Voting, Etc.

               The shares of Company Stock in Accounts, whether or not
         vested, may be voted by the Account Owner to the same extent as if
         duly registered in the Account Owner's name.  The Trustee or its
         nominee in which the shares are registered shall vote the shares
         solely as agent of the Account Owner and in accordance with the
         instructions of the Account Owner.  If no instructions are received,
         the Trustee shall vote the shares of Company Stock for which it has
         received no voting instructions in the same proportions as the Account
         Owners affirmatively directed their shares of Company Stock to be
         voted unless the Trustee determines that a pro rata vote would be
         inconsistent with its fiduciary duties under ERISA.  If the Trustee
         makes such a determination, the Trustee shall vote the Company Stock
         as it determines to be consistent with its fiduciary duties under
         ERISA.  Each Account Owner who has Company Stock allocated to his or
         her Accounts shall direct the Trustee concerning the tender (as
         provided below) and the exercise of any other rights appurtenant to
         the Company Stock.  The Trustee shall follow the directions of the
         Account Owner with respect to the tender.

         14.2  Notices.

               Apache shall cause to be mailed or delivered to each Account
         Owner copies of all notices and other communications sent to the
         Apache shareholders at the same times so mailed or delivered by Apache
         to its other shareholders.

         14.3  Retention/Sale of Company Stock and Other Securities.

               The Trustee is authorized and directed to retain the Company
         Stock and any other Apache securities acquired by the Trust except as
         follows:

                          (a)     In the normal course of Plan administration,
         the Trustee shall sell Company Stock to satisfy Plan administration
         and distribution requirements as directed by the Committee or in
         accordance with provisions of the Plan specifically authorizing such
         sales.

   5
                          (b)     In the event of a transaction involving the
         Company Stock evidenced by the filing of Schedule 14D-1 with the
         Securities and Exchange Commission ("SEC") or any other similar
         transaction by which any person or entity seeks to acquire beneficial
         ownership of 50% or more of the shares of Company Stock outstanding
         and authorized to be issued from time to time under Apache's articles
         of incorporation ("tender offer"), the Trustee shall sell, convey, or
         transfer Company Stock pursuant to written instructions of Account
         Owners delivered to the Trustee in accordance with the following
         Sections 14.4 through 14.15.  For purposes of such provisions, the
         term "filing date" means the date relevant documents concerning a
         tender offer are filed with the SEC or, if such filing is not
         required, the date the Trustee receives actual notice that a tender
         offer has commenced.

                          (c)     If Apache makes any distribution of Apache
         securities with respect to the shares of Company Stock held in the
         Plan, other than additional shares of Company Stock (any such
         securities are hereafter referred to as "stock rights"), the Trustee
         shall sell, convey, transfer, or exercise such stock rights pursuant
         to written instructions of Account Owners delivered to the Trustee in
         accordance with the following Sections of this Article.

         14.4  Tender Offers.

                          (a)     Allocated Stock.  In the event of any tender
         offer, each Account Owner shall have the right to instruct the Trustee
         to tender any or all shares of Company Stock, whether or not vested,
         that are allocated to his or her Accounts under the Plan on or before
         the filing date.  The Trustee shall follow the instructions of the
         Account Owner.  The Trustee shall not tender any Company Stock for
         which no instructions are received.

                          (b)     Unallocated Stock.  The Trustee shall tender
         all shares of Company Stock that are not allocated to Accounts in the
         same proportion as the Account Owners directed the tender of Company
         Stock allocated to their Accounts unless the Trustee determines that a
         pro rata tender would be inconsistent with its fiduciary duties under
         ERISA.  If the Trustee makes such a determination, the Trustee shall
         tender or not tender the unallocated Company Stock as it determines to
         be consistent with its fiduciary duties under ERISA.

   6
                          (c)     Suspension of Share Purchases.  In the event
         of a tender offer, the Trustee shall suspend all purchases of Company
         Stock pursuant to the Plan unless the Committee otherwise directs.
         Until the termination of such tender offer and pending such Committee
         direction, the Trustee shall invest available cash pursuant to the
         applicable provisions of the Plan and the Trust Agreement.

                          (d)     Temporary Suspension of Certain Cash
         Distributions.  Notwithstanding anything in the Plan to the contrary,
         no option to receive cash in lieu of Company Stock shall be honored
         during the pendency of a tender offer unless the Committee otherwise
         directs.

         14.5  Stock Rights.

                          (a)     General.  If Apache makes a distribution of
         stock rights with respect to the Company Stock held in the Plan and if
         the stock rights become exercisable or transferable (the date on which
         the stock rights become exercisable or transferable shall be referred
         to as the "exercise date"), each Account Owner shall determine whether
         to exercise the stock rights, sell the stock rights, or hold the stock
         rights allocated to his or her Accounts.  The provisions of this
         Section shall apply to all stock rights received with respect to
         Company Stock held in Accounts, whether or not the Company Stock with
         respect to which the stock rights were issued are vested.

                          (b)     Independent Fiduciary.  The Independent
         Fiduciary provided for in Section 14.15 below shall act with respect
         to the stock rights.  All Account Owner directions concerning the
         exercise or disposition of the stock rights shall be given to the
         Independent Fiduciary, who shall have the sole responsibility of
         assuring that the Account Owners' directions are followed.

                          (c)     Exercise of Stock Rights.  If, on or after
         the exercise date, an Account Owner wishes to exercise all or a
         portion of the stock rights allocated to his or her Accounts, the
         Independent Fiduciary shall follow the Account Owner's direction to
         the extent that there is cash or other liquid assets available in his
         or her Accounts to exercise the stock rights.  Notwithstanding any
         other provision of the Plan, each Account Owner who has stock rights
         allocated to his or her Accounts shall have a period of five business
         days following the exercise date in which he or she may give
         instructions to the Committee to liquidate any of the assets held in
         his or her Accounts (except shares of Company Stock or assets





                                     - 6 -
   7
         such as guaranteed investment contracts or similar investments), but
         only if he or she does not have sufficient cash or other liquid assets
         in his or her Accounts to exercise the stock rights.  The liquidation
         of any necessary investments pursuant to an Account Owner's direction
         shall be accomplished as soon as reasonably practicable, taking into
         account any timing restrictions with respect to the investment funds
         involved.  The cash obtained shall be used to exercise the stock
         rights, as the Account Owner directs.  Any cash that is not so used
         shall be invested in a cash equivalent until the next date on which
         the Account Owner may change his or her investment directions under
         the Plan.

                          (d)     Sale of Stock Rights.  On and after the
         exercise date, the Independent Fiduciary shall sell all or a portion
         of the stock rights allocated to Accounts, as the Account Owner shall
         direct.

         14.6  Other Rights Appurtenant to the Company Stock.

               If there are any rights appurtenant to the Company Stock,
         other than voting, tender, or stock rights, each Account Owner shall
         exercise or take other appropriate action concerning such rights with
         respect to the Company Stock, whether or not vested, that is allocated
         to their Accounts in the same manner as the other holders of the
         Company Stock, by giving written instructions to the Trustee.  The
         Trustee shall follow all such instructions, but shall take no action
         with respect to allocated Company Stock for which no instructions are
         received.  The Trustee shall exercise or take other appropriate action
         concerning any such rights appurtenant to unallocated Company Stock.

         14.7  Information to Truste.

               Promptly after the filing date, the exercise date, or any
         other event that requires action with respect to the Company Stock,
         the Committee shall deliver or cause to be delivered to the Trustee or
         the Independent Fiduciary, as appropriate, a list of the names and
         addresses of Account Owners showing (i) the number of shares of
         Company Stock allocated to each Account Owner's Accounts under the
         Plan, (ii) each Account Owner's pro rata portion of any unallocated
         Company Stock, and (iii) each Account Owner's share of any stock
         rights distributed by Apache.  The Committee shall date and certify
         the accuracy of such information, and such information shall be
         updated periodically by the





                                     - 7 -
   8
         Committee to reflect changes in the shares of Company Stock and other
         assets allocated to Accounts.

         14.8  Information to Account Owners.

               The Trustee or the Independent Fiduciary, as appropriate,
         shall distribute and/or make available to each affected Account Owner
         the following materials:

                          (a)     A copy of the description of the terms and
         conditions of any tender offer filed with the SEC on Schedule 14D-1,
         or any similar materials if such filing is not required, any material
         distributed to shareholders generally with respect to the stock
         rights, and any proxy statements and any other material distributed to
         shareholders generally with respect to any action to be taken with
         respect to the Company Stock.

                          (b)     If requested by Apache, a statement from
         Apache's management setting forth its position with respect to a
         tender offer that is filed with the SEC on Schedule 14D-9 and/or a
         communication from Apache given pursuant to 17 C.F.R.  240.14d-9(e),
         as amended.

                          (c)     An instruction form prepared by Apache and
         approved by the Trustee or the Independent Fiduciary, to be used by
         any Account Owner who wishes to instruct the Trustee to tender Company
         Stock in response to the tender offer, to instruct the Independent
         Fiduciary to sell or exercise stock rights, or to instruct the Trustee
         or Independent Fiduciary with respect to any other action to be taken
         with respect to the Company Stock.  The instruction form shall state
         that (i) if the Account Owner fails to return an instruction form to
         the Trustee by the indicated deadline, the Trustee will not tender any
         shares of Company Stock the Account Owner is otherwise entitled to
         tender, (ii) the Independent Fiduciary will not sell or exercise any
         right allocated to the Account except upon the written direction of
         the Account Owner, (iii) the Trustee or Independent Fiduciary will not
         take any other action that the Account Owner could have directed, and
         (iv) Apache acknowledges and agrees to honor the confidentiality of
         the Account Owner's directions to the Trustee.

                          (d)     Such additional material or information as
         the Trustee or the Independent Fiduciary may consider necessary to
         assist the Account Owner in making an informed decision and in
         completing or delivering the instruction form (and any amendments
         thereto) to the Trustee or the Fiduciary on a timely basis.

         14.9   Expenses.

                The Trustee and the Independent Fiduciary shall have the right
         to require payment in advance by Apache and the party making the
         tender offer of all reasonably anticipated expenses of the Trustee and
         the Independent Fiduciary, respectively, in connection with the
         distribution of information to and the processing of instructions
         received from Account Owners.

         14.10  Former Account Owners.

                Apache shall furnish former Account Owners who have received
         distributions of Company Stock so recently as to not be shareholders
         of record with the information furnished pursuant to Section 14.8.
         The Trustee and the Independent Fiduciary are hereby authorized to
         take action with respect to the Company Stock distributed to such
         former Account Owners in accordance with appropriate instructions from
         them.  If the Trustee does not receive appropriate instructions, it
         shall take no action with respect to the distributed Company Stock.

         14.11  No Recommendations.

                Neither the Committee, the Committee Fiduciary, the Trustee,
         nor the Independent Fiduciary shall express any opinion or give any
         advice or recommendation to any Account Owner concerning voting the
         Company Stock, any tender offer, stock rights, or the exercise of any
         other rights appurtenant to the Company Stock, nor shall they have any
         authority or responsibility to do so.  Neither the Trustee nor the
         Independent Fiduciary has any duty to monitor or police the party
         making a tender offer or Apache in promoting or resisting a tender
         offer; provided, however, that if the Trustee or the Independent
         Fiduciary becomes aware of activity that on its face reasonably
         appears to the Trustee or Independent Fiduciary to be materially
         false, misleading, or coercive, the Trustee or the Independent
         Fiduciary, as the case may be, shall promptly demand that the
         offending party take appropriate corrective action.  If the offending
         party fails or refuses to take appropriate corrective action, the
         Trustee or the Independent Fiduciary, as the case may be, shall
         communicate with affected Account Owners in such manner as it deems
         advisable.

         14.12  Trustee to Follow Instructions.

                          (a)     So long as the Trustee and the Independent
         Fiduciary, as the case may be, have determined that the Plan is in
         compliance with ERISA section 404(c), the Trustee or the Independent
         Fiduciary shall tender, deal with stock rights, and act with respect
         to any other rights appurtenant to the Company Stock, pursuant to the
         terms and conditions of the particular transaction or event, and in
         accordance with instructions received from Account Owners.  Except for
         voting, the Trustee or the Independent Fiduciary shall take no action
         with respect to Company Stock, stock rights, or other appurtenant
         rights for which no instructions are received, and such Company Stock,
         stock rights, or other appurtenant rights shall be treated like all
         other Company Stock, stock rights, or other appurtenant rights for
         which no instructions are received.  The Trustee, or if an Independent
         Fiduciary has been appointed, the Independent Fiduciary, shall vote
         the allocated Company Stock that an Account Owner does not vote as
         specified in Section 14.1.

                          (b)     If the Trustee or Independent Fiduciary
         determines that the Plan does not satisfy the requirements of ERISA
         section 404(c), the Trustee or Independent Fiduciary shall follow the
         instructions of the Account Owner with respect to voting, tender,
         stock rights, or other rights appurtenant to the Company Stock unless
         the Trustee or Independent Fiduciary determines that to do so would be
         inconsistent with its fiduciary duties under ERISA.  In such case, the
         Trustee or the Independent Fiduciary shall take such action as it
         determines to be consistent with its fiduciary duties under ERISA.

         14.13  Confidentiality.

                          (a)     The Committee shall designate one of its
         members (the "Committee Fiduciary") to receive investment directions
         and to transmit such directions to the Trustee or Independent
         Fiduciary, as the case may be.  The Committee Fiduciary shall also
         receive all Account Owner instructions concerning voting, tender,
         stock rights, and other rights appurtenant to the Company Stock.  The
         Committee Fiduciary shall communicate the instructions to the Trustee
         or the Fiduciary, as appropriate.

                          (b)     Neither the Committee Fiduciary, the Trustee,
         nor the Independent Fiduciary shall reveal or release any instructions
         received from Account Owners concerning the Company Stock to Apache,
         an Affiliated





                                     - 10 -
   11
         Entity, or the officers, directors, employees, agents, or
         representatives of Apache and Affiliated Entities, except to the
         extent necessary to comply with Federal or state law not preempted by
         ERISA.  If disclosure is required by Federal or state law, the
         information shall be disclosed to the extent possible in the aggregate
         rather than on an individual basis.

                          (c)     The Committee Fiduciary shall be responsible
         for reviewing the confidentiality procedures from time to time to
         determine their adequacy.  The Committee Fiduciary shall ensure that
         the confidentiality procedures are followed.  The Committee Fiduciary
         shall also ensure that the Independent Fiduciary provided for in
         Section 14.15 is appointed.

                          (d)     Apache, with the Trustee's cooperation, shall
         take such action as is necessary to maintain the confidentiality of
         Account records including, without limitation, establishment of
         security systems and procedures which restrict access to Account
         records and retention of an independent agent to maintain such
         records.  If an independent recordkeeping agent is retained, such
         agent must agree, as a condition of its retention by Apache, not to
         disclose the composition of any Accounts to Apache, an Affiliated
         Entity or an officer, director, employee, or representative of Apache
         or an Affiliated Entity.

                          (e)     Apache acknowledges and agrees to honor the
         confidentiality of the Account Owners' instructions to the Committee
         Fiduciary, the Trustee, and the Independent Fiduciary.  If Apache, by
         its own act or omission, breaches the confidentiality of Account Owner
         instructions, Apache agrees to indemnify and hold harmless the
         Committee Fiduciary, the Trustee, or the Independent Fiduciary, as the
         case may be, against and from all liabilities, claims and demands,
         damages, costs, and expenses, including reasonable attorneys' fees,
         that the Committee Fiduciary, the Trustee, or the Independent
         Fiduciary may incur as a result thereof.

         14.14  Investment of Proceeds.

                If Company Stock or the rights are sold pursuant to the tender
         offer or the provisions of the rights, the proceeds of such sale shall
         be invested in accordance with the provisions of the Plan and the
         Trust Agreement.

         14.15  Independent Fiduciary.

                Apache shall appoint a fiduciary (the "Independent Fiduciary")
         to act solely with respect to the Company Stock in situations which
         the Committee Fiduciary determines involve a potential for undue
         influence by Apache in connection with the Company Stock and the
         exercise of any rights appurtenant to the Company Stock.  If the
         Committee Fiduciary so determines, it shall give written notice to the
         Independent Fiduciary, which shall have sole responsibility for
         assuring that Account Owners receive the information necessary to make
         informed decisions concerning the Company Stock, are free from undue
         influence or coercion, and that their instructions are followed to the
         extent proper under ERISA.  The Independent Fiduciary shall act until
         it receives written notice to the contrary from the Committee
         Fiduciary.

II.      AMENDMENT TO CHANGE THE MATCHING FORMULA

A.       The first four sentences of Section 3.1(b) shall remain unchanged.
Effective February 1, 1994, the remainder of Section 3.1(b) shall be replaced
by the following.

         As of the last day of each pay period, the Committee shall allocate
         Company Matching Contributions (including such forfeitures occurring
         during the pay period that are treated as Company Matching
         Contributions pursuant to Section 5.5) to each Participant who made
         Participant Before-Tax Contributions during the pay period as follows.
         The Company Matching Contribution allocated to a Participant shall
         equal a "matching percentage" multiplied by that portion of the
         Participant Before-Tax Contributions for the pay period that do not
         exceed 6% of the Participant's Compensation for the pay period.  The
         matching percentage equals 100% unless one or more of the following
         conditions applies, in which case the matching percentage equals 50%.

                                  (i)      The Participant is younger than age
         59-1/2 on the first day of the pay period and the Participant has, in
         the six months preceding the pay period, sold Company Stock from any
         of his or her Accounts.  Sales prior to January 1, 1994 shall be
         ignored.

                                 (ii)      The Participant has elected to
         invest any portion of the pay period's Company Matching Contribution
         in an investment option other than Company Stock.  The matching
         percentage is 50% only to the extent that this condition applies.





                                     - 12 -
   13
                                (iii)      The Participant has elected to
         invest any portion of the pay period's Participant Before-Tax
         Contribution in an investment other than Company Stock.  The matching
         percentage is 50% only to the extent that this condition applies.  The
         matching percentage shall be applied first to the Participant
         Before-Tax Contributions that are invested in Company Stock.  For
         example, if Paragraphs (i) and (ii) do not apply, and if a Participant
         contributes 10% of Compensation as a Participant Before-Tax
         Contribution in the pay period and he or she elects to invest half the
         contribution in Company Stock and half in another investment option,
         then the Participant's allocation of Company Matching Contributions
         for the pay period will equal 100% of 5% of the pay period's
         Compensation plus 50% of 1% of the pay period's Compensation, for a
         total match of 5-1/2% of Compensation; the remaining Participant
         Before-Tax Contribution (of 4% of the Participant's Compensation) will
         not be matched.

III.     AMENDMENT TO ACCOMMODATE THE CAFETERIA PLAN.

A.       Effective January 1, 1994, the first sentence of Section 3.4(b) shall
replaced by the following.

                 If, as a result of a reasonable error in estimating
         Compensation, or as a result of the allocation of forfeitures, or as a
         result of other facts and circumstances as provided in the regulations
         under Code section 415, the Annual Additions to a Participant's
         Account(s) would, but for this Subsection, exceed the foregoing
         limits, the Annual Additions shall be reduced, to the extent
         necessary, in the following order:  unmatched Participant Before-Tax
         Contributions, then matched Participant Before-Tax Contributions and
         the corresponding Company Matching Contributions, and then Company
         Mandatory Contributions.

IV.      AMENDMENTS DEALING WITH CHANGES IN THE LAW.

A.       Effective January 1, 1993, the references to Code section 402(a)(8)
(in Sections 1.12(d) and 1.36 of the Plan) shall be changed to Code section
402(e)(3).

B.       Effective January 1, 1993, the following new section shall be added to
the Plan.

         6.6  Direct Rollover Election.

              This Section is effective January 1, 1993.  A Participant, an
         Alternate Payee who is the Spouse or former Spouse of the Participant,
         or a surviving Spouse of a deceased Participant (collectively, the





                                     - 13 -
   14
         "distributee") may direct the Trustee to pay all or any portion of his
         or her "eligible rollover distribution" to an "eligible retirement
         plan" in a "direct rollover."  Within a reasonable period of time
         before an eligible rollover distribution, the Committee shall inform
         the distributee of this direct rollover option, the appropriate
         withholding rules, other rollover options, the options regarding
         income taxation, and any other information required by Code section
         402(f).

                 An "eligible rollover distribution" is any distribution or
         in-service withdrawal other than (a) distributions required under Code
         section 401(a)(9), (b) distributions of amounts that have already been
         subject to federal income tax (such as defaulted loans or after-tax
         voluntary contributions), (c) installment payments in a series of
         substantially equal payments made at least annually and (i) made over
         a specified period of ten or more years, (ii) made for the life or
         life expectancy of the distributee, or (iii) made for the joint life
         or joint life expectancy of the distributee and his or her designated
         beneficiary, (d) a distribution to satisfy the limits of Code section
         415 or 402(g), (e) a distribution to satisfy the ADP, ACP, or multiple
         use tests, or (f) any other actual or deemed distribution specified in
         the regulations issued under Code section 402(c).

                 For a Participant or an Alternate Payee who is the Spouse or
         former Spouse of the Participant, an "eligible retirement plan" is an
         individual retirement account or annuity described in Code section
         408(a) or 408(b), an annuity plan described in Code section 403(a), or
         the qualified trust of a defined contribution plan that accepts
         eligible rollover distributions.  For a surviving Spouse of a deceased
         Participant, an "eligible retirement plan" is an individual retirement
         account or annuity.

                 A "direct rollover" is a payment by the Trustee to the
         eligible retirement plan specified by the distributee.

C.       Effective January 1, 1989, the following paragraph shall be added to
the end of Subsection 3.6(c).

                                 (iv)      Those vested Company Matching
         Contributions and those Participant Before-Tax Contributions that are
         taken into account for this ACP test for any Highly Compensated
         Employee may be returned to such Highly Compensated Employee, without
         the consent of either the Highly Compensated Employee or his or her





                                     - 14 -
   15
         Spouse, subject to the rules of Subsection (d).  Any such return of
         Participant Before-Tax Contributions or vested Company Matching
         Contributions shall be made within two and one-half months after the
         close of the Plan Year if possible, and in no event later than 12
         months after the close of the Plan Year.

D.       Effective January 1, 1989, the phrase "Section 3.5 or 3.7" in the
fourth sentence of Subsection 3.2(b) shall be replaced by the phrase "Section
3.4, 3.5, or 3.7."

E.       Effective January 1, 1989, subsection 3.8(d) shall be deleted.

F.       Effective January 1, 1989, the following sentence shall be added to
the end of Paragraph 6.5(a)(iv).

         However, distribution from a Participant Before-Tax Contribution
         Account shall not occur pursuant to this Paragraph until either the
         Participant has separated from service within the meaning of Code
         section 401(k)(2)(B)(i)(I) or the Participant has been affected by a
         corporate transaction described in Code section 401(k)(10)(A)(ii) or
         Code section 401(k)(10)(A)(iii).

V.       AMENDMENTS FOR QDROS.

A.       Effective January 1, 1993, Sections 6.1 and 6.2 shall be replaced in
their entirety by the following.

         6.1  Beneficiaries.

                          (a)     Each Account Owner shall file with the
         Committee a designation of the beneficiaries and contingent
         beneficiaries to whom the distributable amount (determined pursuant to
         Section 6.3) shall be paid in the event of his or her death.  In the
         absence of an effective beneficiary designation as to any portion of
         the distributable amount after a Participant dies, such amount shall
         be paid to the Participant's surviving Spouse, or, if none, to his or
         her estate.  In the absence of an effective beneficiary designation as
         to any portion of the distributable amount after any non-Participant
         Account Owner dies, such amount shall be paid to the Account Owner's
         estate.

                          (b)     A beneficiary designation may be changed by
         the Account Owner at any time and without the consent of any
         previously designated beneficiary.  However, if the Account Owner is a
         married Participant, his or her Spouse shall be his or her beneficiary
         unless his or her Spouse has consented to the designation of a
         different





                                     - 15 -
   16
         beneficiary.  To be effective, the Spouse's consent must be in
         writing, witnessed by a notary public, and filed with the Committee.
         Any such election shall be effective only as to the Spouse who signed
         the election.  Effective as of July 23, 1992, if a Participant has
         designated his or her Spouse as his or her beneficiary, and the
         Participant and that Spouse subsequently divorce, then the beneficiary
         designation shall be void and of no effect on the day such divorce is
         final.

         6.2  Consent.

                          (a)     Except for distributions identified in
         Subsection (b), distributions may be made only after the appropriate
         consent has been obtained under this Subsection.  Distributions to a
         Participant shall be made only with the Participant's consent to the
         manner of distribution and the time of distribution.  Distributions to
         a beneficiary of a deceased Participant shall be made only with the
         beneficiary's consent to the manner of distribution and the time of
         distribution.  Distributions to an Alternate Payee or his or her
         beneficiary shall be made as specified in the QDRO.  To be effective,
         the consent must be in writing, signed by the distributee, and filed
         with the Committee within 90 days before the distribution is to
         commence.  A consent once given shall be irrevocable after
         distribution has begun.  Nevertheless, if a distributee has elected to
         receive his or her distribution in the form of installments, he or she
         may elect to accelerate any or all remaining installments.

                          (b)     Consent is not required for the following
         distributions:

                                  (i)      Corrective distributions under
         Article III that are returned to the Participant because the
         contribution is not deductible by the Company or because the
         contribution would exceed the limits of Code sections 415(c)(1),
         415(e), 402(g), 401(k)(3), 401(m)(2), or 401(m)(9);

                                 (ii)      Distributions that are required to 
         comply with Code section 401(a)(9);

                                (iii)      Immediate cashouts of less than
         $3,500, if the aggregate value of the nonforfeitable portion of a
         Participant's Accounts is $3,500 or less (calculated in accordance
         with the applicable Treasury regulations) on the earliest date the
         Participant (or his or her beneficiary if the Participant has not
         received





                                     - 16 -
   17
         any distributions) may elect to receive a distribution under Section
         6.5 after the Participant has terminated employment;

                                 (iv)      Distributions pursuant to Code 
         section 401(a)(14); and

                                  (v)      Distributions after the later of the
         Participant's Normal Retirement Age or age 62, provided that the
         Participant has terminated employment before the distribution is made.

B.       Effective January 1, 1993, the phrase "Paragraphs (f)(ii) and
(f)(iii)" in Subsection 13.9(c) shall be replaced with the phrase "Subsection
(f)."

C.       Effective January 1, 1993, Subsection 13.9(d) shall be replaced in its
entirety with the following.

                          (d)     In the case of any payment before an Employee
         has separated from service, a Domestic Relations Order shall not be
         treated as failing to meet the requirements of Subsection (c) solely
         because such order requires that payment of benefits be made to an
         Alternate Payee (i) on or after the dates specified in Subsection (f),
         (ii) as if the Employee had retired on the date on which such payment
         is to begin under such order (but taking into account only the Account
         balance on such date), and (iii) in any form in which such benefits
         may be paid under the Plan to the Employee.  For purposes of this
         Subsection, the Account balance as of the date specified in the QDRO
         shall be the vested portion of the Employee's Account(s) on such date.

D.       Effective January 1, 1993, Subsection 13.9(f) shall be replaced in its
entirety with the following.

                          (f)     The Alternate Payee shall have the following
         rights under the Plan:

                                  (i)      An Alternate Payee shall receive a
         lump sum distribution of his or her Plan assets as soon as
         administratively practicable after the Committee determines that the
         Domestic Relations Order is a QDRO.

                                 (ii)      If the Alternate Payee cannot
         receive an immediate distribution of his or her entire interest in the
         Plan (which could occur if the Alternate Payee is awarded more than
         the distributable amount in Section 6.3), then the Alternate Payee
         shall receive an immediate lump sum distribution of the distributable
         amount.  The





                                     - 17 -
   18
         Alternate Payee's remaining interest in the Plan shall be distributed
         as soon as administratively practicable, in annual lump sums of the
         distributable amount on the first day of the year.  Upon the Alternate
         Payee's death, his or her interest in the Plan shall be distributed in
         a lump sum as soon as practicable.

                                (iii)      Distribution to an Alternate Payee
         must occur on or before the Participant's Required Beginning Date.

                                 (iv)      The Alternate Payee may bring claims
         against the Plan in the same manner as a Participant pursuant to
         Section 13.2.

C.       Effective January 1, 1994, the following Appendix B shall be added to
the end of the Plan.

                                   APPENDIX B

                      HADSON ENERGY RESOURCES CORPORATION

                                  Introduction

                 Through a merger effective November 12, 1993, Apache now holds
         100% of the capital stock of Hadson Energy Resources Corporation
         ("HERC").  HERC and its wholly owned subsidiary, Hadson Energy Limited
         ("HEL"), maintained the Hadson Energy Resources Corporation Employee
         401(k) Plan (the "HERC Plan"), a profit sharing plan containing a cash
         or deferred arrangement.  The HERC Plan was terminated as of December
         31, 1993.  Amounts will be transferred from the HERC Plan to this Plan
         as soon as administratively feasible after the Internal Revenue
         Service issues a favorable ruling with respect to the termination of
         the HERC Plan.  The transferred amounts will be accounted for
         separately, and different distributional options will apply to them,
         as described below.  In addition, HERC and HEL have adopted this Plan,
         and Apache has approved their adoption, as of January 1, 1994 for
         HERC's and HEL's eligible employees.  The employees will be given
         credit in this Plan, for vesting and eligibility purposes, for their
         prior service with HERC and HEL.

                 This Appendix is intended to encompass all the protected
         benefits and optional forms of benefit, as





                                     - 19 -
   20
         required by Code section 411(d)(6), with respect to amounts
         transferred from the HERC Plan and shall be interpreted consistently
         with that intent.

                 Capitalized terms in this Appendix have the same meanings as
         those given to them in the Plan.

                                    Service

                 This Appendix applies to all individuals who are common-law
         employees of HERC or HEL ("Current HERC Employees") as of January 1,
         1994.  A Period of Service for a Current HERC Employee shall include
         any periods of employment with HERC, HEL, and any of HERC's
         subsidiaries.

                                 Participation

                 Notwithstanding Sections 2.1 and 3.1, a Current HERC Employee
         who is a Covered Employee shall be eligible to begin to make
         Participant Before-Tax Contributions, and shall be eligible to
         participate in the Plan with respect to the 6% Company Mandatory
         Contribution, on January 1, 1994.

                              Transfer of Accounts

                 The Trustee is authorized to accept the direct transfer of all
         assets from the trustee of the HERC Plan.  The assets may be
         transferred in kind or in cash, as determined by the Committee.  The
         Trustee shall accept a direct transfer of any participant loan from
         the HERC Plan; such loan shall continue to be administered according
         to the terms of its promissory note.  The Committee shall establish
         such procedures, rules, and regulations as it deems necessary or
         appropriate to accommodate the transfer of assets.  The Trustee shall
         separately account for all assets directly transferred to this Plan.
         The Trustee shall establish the following accounts for each individual
         whose account(s) are transferred to this Plan:  a Voluntary
         Contribution Account (containing participant after-tax contributions
         and the investment earnings thereon); a Salary Deferral Account
         (containing participant before-tax contributions and the investment
         earnings thereon); a QNEC/QMAC Account (containing qualified
         non-elective contributions, qualified matching contributions, and the
         investment earnings thereon); and a HERC Contributions Account
         (containing the employer's matching contributions, the employer's
         discretionary contributions, and the





                                     - 20 -
   21
         investment earnings thereon) (collectively, the "HERC Accounts").

                                 Distributions

                 Unless waived in writing by the Participant or other
         beneficiary after such person becomes entitled to a distribution from
         the Plan by reason of a Participant's death, Disability, retirement,
         or other termination of employment with the Company, or a termination
         or partial termination of the Plan, then in addition to and
         notwithstanding any other provisions of the Plan, the Participant or
         other beneficiary shall have the right to receive his or her vested
         interest in the balance of his or her HERC Accounts in the following
         optional forms and at the following times.  The annuity requirements,
         below, however, are automatic with respect to the HERC Account
         balances unless waived as provided for therein.

                 To the extent that this Appendix does not provide for an
         alternative or contrary requirement or procedure for distribution of a
         Participant's HERC Account, the provisions of the Plan shall control.
         For example, all of the consent and beneficiary designation provisions
         of the Plan govern the distribution of HERC Accounts to the extent not
         inconsistent with the annuity requirements below, and all
         distributions are subject to the direct rollover rules of Section 6.6.

                 Whether or not specifically stated hereinafter, the following
         provisions apply only to the HERC Account balances.

         1.      Death or Disability.

                 Distributions pursuant to the Plan provisions control in the
         case of distributions as a result of death or Disability, except to
         the extent that the annuity requirements below are applicable, and
         except that installment payments are not available.

         2.      Other than Death or Disability.

                 Distributions for reasons other than the Participant's death
         or Disability shall be made in accordance with the following:

                 A Participant who has attained age 59-1/2 may withdraw any
         vested amount from his or her HERC Accounts at any time, regardless of
         whether the Participant has terminated employment with HERC.





                                     - 21 -
   22
                  A Participant may elect to withdraw any vested amount from his
         or her HERC Accounts at any time after separating from service (within
         the meaning of Code section 401(k)(2)(B)(i)(I)) with Apache, HERC, and
         all Affiliated Entities.

                  A Participant may elect to withdraw any amount from his or her
         Voluntary Contributions Account at any time, regardless of whether the
         Participant has terminated employment with HERC.

                  A Participant younger than 59-1/2 who has not separated from
         service with Apache, HERC, and Affiliated Entities, may make a
         hardship withdrawal from his or her Salary Deferral Account under the
         same terms and conditions described in Section 7.1(b) of the Plan.

                  Notwithstanding any of the foregoing early distribution
         options, a Participant whose vested interest in his or her HERC
         Account balances are distributed pursuant to one of the options
         contained in this Paragraph 2 shall forfeit his or her nonvested
         interest in his or her HERC Account balances only as of the last day
         of the Plan Year in which the Participant incurs a one-year Lapse in
         Apache Employment.

                  All distributions made pursuant to this Paragraph 2 shall be
         made in a manner that is consistent with, and satisfies the provisions
         of, Paragraph 4 below, including, but not limited to, all notice and
         consent requirements of Code sections 417 and 411(a)(11) and the
         Treasury Regulations thereunder.

         3.       Qualified Single Life or Joint and Survivor Annuity.

                  (a)      Eligibility and Conditions.  Unless the Participant
         elects, as provided in 3(c), not to receive benefits in the form of a
         qualified joint and survivor annuity, benefits attributable to HERC
         Account balances will be paid in a form having the effect of a
         qualified joint and survivor annuity (as defined in 3(b)(2)) with
         respect to any Participant who (1) is entitled to a distribution, and
         (2) satisfies the marriage requirements provided in 3(d)(2).  In a
         similar fashion, if a Participant does not meet the marriage
         requirements, such benefits will be paid in a form having the effect
         of a single life annuity unless the Participant elects, similar to the
         election pursuant to 3(c) but without the spousal consent requirement,
         to waive the life annuity.

                  (b)     Definitions.  As used in this Paragraph

                          (1)     Life Annuity.  The term "life annuity" means
         an annuity that provides retirement payments and requires the survival
         of the Participant or the Participant's spouse as one of the
         conditions for any payment or possible payment under the annuity.

                          (2)     Qualified Joint and Survivor Annuity.  The
         term "qualified joint and survivor annuity" means an annuity for the
         life of the Participant with a survivor annuity for the life of the
         Participant's spouse which is one-half of the amount of the annuity
         payable during the joint lives of the Participant and his or her
         spouse.  A qualified joint and survivor annuity shall be the actuarial
         equivalent of a life annuity for the life of the Participant.  The
         Committee shall direct the Trustee to apply the entire vested amount
         in all of the Participant's HERC Accounts (whether vested before or
         upon death, including the proceeds of insurance contracts) to the
         purchase of an annuity contract that satisfies all of the requirements
         of this Paragraph 3 and to distribute the contract to the Participant.
         Payments to the spouse of a deceased Participant shall not be
         terminated or reduced because of such spouse's remarriage.

                          (3)     Normal Retirement Age.  The term "normal 
         retirement age" means the Participant's 65th birthday.

                          (4)     Annuity Starting Date.  The term "annuity
         starting date" means (i) the first day of the first period for which
         an amount is payable as an annuity, whether by reason of retirement or
         by reason of Disability, or (ii) in the case of a benefit not payable
         in the form of an annuity, the first day on which all events have
         occurred which entitled the Participant to such benefit.

                          (5)     Day.  The term "day" means a calendar day.

                 (c)      Election Not to Take Joint and Survivor Annuity.

                          (1)     In General.  Each Participant may elect, at
         any time during the election period described in 3(c)(3), not to
         receive a qualified joint and survivor annuity.  The election shall be
         in writing and clearly indicate that the Participant is electing to
         receive all of his or her benefits under the Plan in a form other than
         that of a qualified joint and survivor annuity.





                                     - 23 -
   24
                          (2)     Consent of Spouse.  An election under 3(c)(1)
         above shall not be effective unless (i) the Participant's spouse
         consents in writing to the election, (ii) the election designates a
         beneficiary (or a form of benefits) which may not be changed without
         spousal consent (or the consent of the spouse expressly permits
         designations by the Participant without any requirement of further
         consent by the spouse) and (iii) the spouse's consent acknowledges the
         effect of the election and the consent is witnessed by a Committee
         member or a notary public.  The spouse's consent shall be filed with
         the Committee at the same time that the Participant's election under
         3(c)(1) is filed with the Committee.  If a spousal consent is not
         filed together with the Participant's election, the election shall
         take effect nevertheless if it is established to the satisfaction of
         the Committee that the Participant is not married, the Participant's
         spouse cannot be located, or that other circumstances prescribed in
         the Treasury Regulations exist.  Any spousal consent or establishment
         that spousal consent cannot be obtained shall be effective only with
         respect to such spouse.

                          (3)     Election period.  The Participant shall have
         an election period which shall be a 90-day period ending on the
         annuity starting date.  If a Participant makes a request for
         additional information as provided in 3(c)(4) below on or before the
         last day of the election period, the election period shall be extended
         to the extent necessary to include the 90 calendar days immediately
         following the day the requested additional information is personally
         delivered or mailed to the Participant.

                          (4)     Information to be Provided by Plan 
         Administrator.

                                  (i)      The Plan Administrator shall provide
                 to the Participants, at the time and in the manner specified
                 in 3(c)(4)(ii), the following information, as applicable to
                 the HERC Account balances under the Plan, written in
                 nontechnical language:

                                           (A)     A general explanation of the
                 terms and conditions of the qualified joint and survivor
                 annuity; the Participant's right to make, and the effect of,
                 an election to waive the joint and survivor annuity form of
                 benefit; the right of the Participant's spouse to consent to
                 any election to waive the joint and survivor annuity; the
                 right





                                     - 24 -
   25
                 to revoke an election to waive; and the effect of such a 
                 revocation; and

                                           (B)     A general explanation of the
                 relative financial effect on a Participant's annuity of the
                 election.  Various methods may be used to explain such
                 relative financial effect, including information as to the
                 benefits the Participant would receive under the qualified
                 joint and survivor annuity stated as an arithmetic or
                 percentage reduction from a single life annuity; a table
                 showing the difference between a straight life annuity and a
                 qualified joint and survivor annuity in terms of a reduction
                 in dollar amounts or a table showing a percentage reduction
                 from the straight life annuity.  The notice and explanation
                 required by this 3(c)(4)(i) must also inform the Participant
                 of the availability of the additional information specified in
                 3(c)(4)(iii) and how such information may be obtained.

                                 (ii)      The method or methods used to
                 provide the information may vary.  If mail or personal
                 delivery is used, then, whether or not the information has
                 been previously provided, there must be a mailing or personal
                 delivery of the information by such time as to reasonably
                 assure that it will be received on a date that is no less than
                 30 days and no more than 90 days before the annuity starting
                 date.  If a method other than mail or personal delivery is
                 used to provide Participants with some or all of such
                 information, it must be a method that is reasonably calculated
                 to reach the attention of a Participant on or about the date
                 prescribed in the immediately preceding sentence and to
                 continue to reach the attention of such Participant during the
                 election period applicable to the Participant for which the
                 information is being provided (as, for example, by permanent
                 posting, repeated publication, etc.).

                                (iii)      The Plan Administrator must furnish
                 to a particular Participant, upon a timely written request, a
                 written explanation in nontechnical language of the terms and
                 conditions of the qualified joint and survivor annuity and the
                 financial effect upon the particular Participant's annuity of
                 making any election under this Paragraph.  Such financial
                 effect shall be given in terms of dollars per annuity payment.
                 The Plan Administrator need not comply with more than one





                                     - 25 -
   26
                 such request made by a particular Participant.  This
                 explanation must be personally delivered or mailed (first
                 class mail, postage prepaid) to the Participant within 30 days
                 from the date of the Participant's written request.

                          (5)     Election is Revocable.  Any election made
         under this 3(c) may be revoked in writing at any time during the
         specified election period, and after such election has been revoked,
         another election under this Paragraph may be made at any time during
         the specified election period.

                          (6)     Election by Surviving Spouse.  The spouse of
         a deceased Participant may elect to have the benefits attributable to
         HERC Account balances paid in a form other than a survivor annuity.
         The Plan Administrator must furnish to the spouse, within a reasonable
         amount of time after a written request has been made by the spouse, a
         written explanation in nontechnical language of the survivor annuity
         and any other form of payment which may be selected.  This explanation
         must state the financial effect (in terms of dollars) of each form of
         payment.  The Plan Administrator need not respond to more than one
         such request.

         (d)     Additional Plan Provisions.

                          (1)     Claim for Benefits.  As a condition precedent
         to the payment of benefits, a Participant must express in writing to
         the Plan Administrator the form in which he or she prefers benefits to
         be paid and provide all the information reasonably necessary for the
         payment of such benefits.  However, if a Participant files a claim for
         benefits with the Plan Administrator and provides the Plan
         Administrator with all the information necessary for the payment of
         benefits but does not indicate a preference as to the form for the
         payment of benefits, benefits attributable to HERC Account balances
         must be paid in the form of a qualified joint and survivor annuity if
         the Participant has attained normal retirement age unless such
         Participant has made an effective election not to receive benefits in
         such form.

                          (2)     Marriage Requirements.

                                  (i)      In General.  A joint and survivor 
                 annuity will be paid only if

                                           (A)     the Participant and his or 
                 her spouse have been married to each other throughout a





                                     - 26 -
   27
                 period of one year ending on the annuity starting date; and

                                           (B)     the Participant shall notify
                 the Plan Administrator of his or her marital status within 30
                 days after request is made for such information.

                                 (ii)      Special Rule.  If a Participant
                 marries within one year before his or her annuity starting
                 date and if the Participant and such spouse have been married
                 for at least a one year period that ends on or before the
                 Participant's date of death, the Participant and such spouse
                 shall be treated as having been married throughout the
                 one-year period ending on the Participant's annuity starting
                 date.

                          (3)        Effect of Participant's Death on an
         Election or Revocation of Election.  The effect of an election or a
         revocation of an election timely made under 3(c) shall not be altered
         by the death of the Participant within any particular time period
         after such election or revocation shall be made effective.

                 (e)      Amount of Benefits.  The amount of benefits shall be
         as provided in 3(b).

                 (f)      Commencement and Duration.  The monthly surviving
         spouse's benefit shall be payable to the spouse for life, beginning as
         of the first day of the calendar month coincident with or next
         following the Participant's death.

4.       Qualified Preretirement Survivor Annuity.

         (a)     Eligibility and Conditions.  Unless the Participant elects, as
provided in 4(c), to waive death benefits in the form of a qualified
preretirement survivor annuity, death benefits attributable to HERC Account
balances will be paid in a form having the effect of a qualified preretirement
survivor annuity (as defined in Paragraph 4(b)(2)) with respect to any
Participant who (1) dies prior to the annuity starting date, and (2) satisfies
the marriage requirement of 4(d).

         (b)     Definitions.  As used in this Paragraph

                 (1)      Life Annuity.  The term "life annuity" means an
annuity that provides retirement payments and requires the survival of the
Participant or the Participant's spouse as one of the conditions for any
payment or possible payment under the annuity.





                                     - 27 -
   28
                 (2)      Qualified Preretirement Survivor Annuity.  The term
"qualified preretirement survivor annuity" means an annuity for the life of the
surviving spouse of the Participant, which is the actuarial equivalent of 100%
of the Participant's HERC Account balance as of his or her date of death.  The
Committee shall direct the Trustee to purchase an annuity contract that
satisfies all of the requirements of this Paragraph 4 (provided that the
present value of the annuity contract is not less than 50% of the Participant's
vested amount in all of his or her HERC Accounts at his or her date of death,
whether vested before or upon death, including the proceeds of insurance
contracts) and to distribute the annuity contract to the surviving spouse.

                 (3)      Normal Retirement Age.  The term "normal retirement
age" means the Participant's 65th birthday.

                 (4)      Annuity Starting Date.  The term "annuity starting
date" means (i) the first day of the first period for which an amount is
payable as an annuity, whether by reason of retirement or by reason of
Disability or (ii) in the case of a benefit not payable in the form of an
annuity, the first day on which all events have occurred which entitled the
Participant to such benefit.

                 (5)      Day.  The term "day" means a calendar day.

         (c)     Election to Waive Qualified Preretirement Survivor  Annuity.

                 (1)      In General.

                          (i)     Each Participant may elect, during the
         election period described in 4(c)(3), to waive the payment of death
         benefits in the form of a qualified preretirement survivor annuity.

                         (ii)     The election shall be in writing and clearly
         indicate that the Participant is electing to waive the payment of
         death benefits in the form of a qualified preretirement survivor
         annuity.

                 (2)      Consent of Spouse.  An election under 4(c)(1) shall
         not be effective unless (i) the Participant's spouse consents in
         writing to the election, (ii) the election designates a beneficiary
         (or a form of benefits) which may not be changed without spousal
         consent (or the consent of the spouse expressly permits the
         designations by the Participant without any requirement of further
         consent by the spouse) and (iii) the spouse's consent acknowledges the
         effect of the election and the consent is witnessed by a Committee
         member or a notary public.





                                     - 28 -
   29
         The spouse's consent shall be filed with the Committee at the same
         time that the Participant's election under 4(c)(1) is filed with the
         Committee.  If a spousal consent is not filed together with the
         Participant'selection, the election shall take effect nevertheless if
         it is established to the satisfaction of the Committee that the
         Participant is not married, the Participant's spouse cannot be
         located, or that other circumstances prescribed in the Treasury
         Regulations exist.  Any spousal consent or establishment that spousal
         consent cannot be obtained shall be effective only with respect to
         such spouse.

                 (3)      Election period.  The Participant shall have an
         election period which shall be a period that ends the later of (i) the
         period beginning with the first day of the Plan Year in which the
         Participant attains age 32 and ending with the close of the Plan Year
         preceding the Plan Year in which the Participant attains age 35, (ii)
         a reasonable time after the individual becomes a Participant, (iii) a
         reasonable time after the preretirement survivor annuity ceases to be
         a fully subsidized benefit, (iv) a reasonable time after the joint and
         survivor rules become effective to the Participant or (v) a reasonable
         time after the Participant separates from service before attaining age
         35.

                 (4)      Information to be Provided by Plan Administrator.

                          (i)     The Plan Administrator shall provide to the
         Participants, at the time and in the manner specified in 4(c)(4), the
         following information, as applicable to the Plan, written in
         nontechnical language:

                                  (A)      A general explanation of the
         qualified preretirement survivor annuity; the Participant's right to
         make, and the effect of, an election to waive the preretirement
         survivor annuity form of death benefit; the right of the Participant's
         spouse to consent to the election to waive the preretirement survivor
         annuity; the right to revoke an election to waive; and the effect of
         such a revocation.

                                  (B)      A general explanation of the
         relative financial effect on a Participant's death benefits of the
         election.  Various methods may be used to explain such relative
         financial effect.





                                     - 29 -
   30
                         (ii)     The method or methods used to provide the
         information may vary.  If mail or personal delivery is used, then,
         whether or not the information has been previously provided, there
         must be a mailing or personal delivery of the information by such time
         as to reasonably assure that it will be received within the period
         commencing with the first day of the Plan Year in which the
         Participant attains age 32 and ending with the last day of the Plan
         Year preceding the Plan Year in which the Participant attains age 35.
         If a method other than mail or personal delivery is used to provide
         Participants with some or all of such information, it must be a method
         that is reasonably calculated to reach the attention of a Participant
         on or about the date prescribed in the immediately preceding sentence
         and to continue to reach the attention of such Participant during the
         election period applicable to the Participant for which the
         information is being provided (as, for example, by permanent posting,
         repeated publication, etc.).

                 (4)         Election is Revocable.  Any election made under
this Paragraph 4 may be revoked in writing at any time during the specified
election period, and after such election has been revoked, another election
under this Paragraph may be made at any time during the specified election
period.

                 (5)         Election by Surviving Spouse.  The surviving
spouse may elect to have benefits paid in a form other than a preretirement
survivor annuity.  The Plan Administrator must furnish to the spouse, within a
reasonable amount of time after a written request has been made by the spouse,
a written explanation in nontechnical language of the preretirement survivor
annuity and any other form of payment that may be selected.  The explanation
must state the financial effect (in terms of dollars) of each form of payment.
The Plan Administrator need not respond to more than one such request.

         (d)     Marriage Requirement.  A preretirement survivor annuity will
be paid only if the Participant and his or her spouse have been married to each
other throughout a period of one year ending on the date of the Participant's
death.

         (e)     Amount of Benefits.  The amount shall be as provided in 4(b).

         (f)     Commencement and Duration.  The monthly surviving spouse's
benefit shall be payable to the spouse for life, beginning as of the first day
of the calendar month coincident with or next following the Participant's
death.
