                                   ARTICLE II

                             ESTABLISHMENT OF TRUST

2.1      PURPOSE.  This Trust is hereby established by Corporation and the
         Trustee for the sole purpose of creating a fund to provide for the
         payment of deferred compensation to the Plan Participants.

2.2      IRREVOCABLE SUBJECT TO CERTAIN EXCEPTIONS.  Subject only to the
         exceptions in this section all contributions to, all assets held in,
         and all earnings of this Trust are solely and irrevocably dedicated to
         the payment of (a) the deferred compensation described in the Plan for
         the benefit of the Participants and (b) the reasonable expenses of
         administering the Trust until the Plan has been satisfied in full, at
         which time the Trust will terminate as provided in Section 10.3.
         Provided, however, the assets held in the Trust will be subject to
         judgment creditors of Corporation and will be subject to the general
         creditors of Corporation if Corporation becomes insolvent.  To that
         end if the Trustee receives notice from Corporation pursuant to
         Section 5.3, the Trustee will suspend payment of all benefits under
         the Trust, and will hold all assets of the Trust for the benefit of
         Corporation's judgment creditors and/or general creditors as the case
         may be.  Further, if the Trustee receives written allegations of
         Corporation's insolvency from any other source, the Trustee will
         suspend the payment of all benefits under the Trust, and will hold all
         of the Trust's assets for the benefit of Corporation's general
         creditors, and must determine within 30 days whether Corporation is
         solvent.  However, the Trustee will resume payments, including any
         benefits suspended, if it determines Corporation is solvent.  In the
         case of the Trustee's actual knowledge of a levy on the assets of the
         Trust by a judgment creditor or the Trustee's actual knowledge of or
         determination of Corporation's insolvency, the Trustee will deliver
         the assets of the Trust as directed by a court of competent
         jurisdiction.

                                  ARTICLE III

                     CONTRIBUTIONS AND PLAN ADMINISTRATION

3.1      CONTRIBUTIONS.  Corporation may contribute in cash or assets to the
         Trust established for it the cost of providing benefits under the Plan
         for the Participants at such time or times and in the manner
         determined by Corporation.

3.2      ESTABLISHING CONTRIBUTION ACCOUNTS FOR PARTICIPANTS.  Corporation
         will, at the time of its contribution, notify the Committee as to the
         Participant for which the contribution is made so that the Committee
         may maintain separate records for the accounts of the Participants who
         are being funded by the Trust.

3.3      VALUATION OF TRUST; ALLOCATION OF GAINS AND LOSSES TO PARTICIPANTS'
         ACCOUNTS.  The Trustee will provide to the Committee, at intervals
         agreed upon by them, but no less often than once each Plan Year, a
         statement of the value of the Trust assets and the Trust income and
         losses.

3.4      RETURN OF EXCESS ASSETS TO COMPANY.  Corporation may at any time
         request the plan consultant who administers the plan (or in the case
         of a Change of Control, administered it just prior to the Change of
         Control) to determine the present value of the Accounts as determined
         under the Plan.  If the fair market value of the assets held in the
         Trust, as determined by the Trustee as of that same date, exceeds the
         total of the Accounts of all Participants and Beneficiaries by 25
         percent, Corporation may direct the Trustee to return to it all of the
         excess funds.



                                   ARTICLE IV

         to receive, hold, preserve, protect, conserve, manage and invest the
         Trust funds as provided generally in this agreement and to pay all
         costs and expenses.  The Trustee will be responsible only for the sums
         actually received by it as Trustee and will not be responsible for
         determining the amount necessary to fund the Trust or for collecting
         any contributions from Corporation.

4.2      INVESTMENT RESPONSIBILITY OF TRUSTEE.  Except as set forth in the
         following paragraphs of this section, the Trustee is required to
         invest the Trust assets solely in U.S. Treasury obligations which
         mature in three years or less unless and until the Committee (a)
         issues a different investment direction, (b) directs the Trustee to
         assume full investment responsibilities for the Trust or (c) directs
         the Trustee to accept the direction of one or more investment managers
         appointed by the Committee.  If the Committee issues an investment
         direction, permits the Trustee to assume full investment
         responsibility or appoints one or more investment managers to direct
         the investment of a portion of the Trust assets, the Trustee is
         authorized and

         empowered to hold any asset, whether or not productive of income or
         whether consisting of wasting assets, and to invest in any assets of
         any kind or nature, whether real, personal or mixed, whether tangible
         or intangible, in any rights or interests in property, or in any
         evidence or indicia of property, including but not limited to the
         following types of properties or interests therein, or anything of a

         any corporate trustee or any other corporation may now have or in the
         future may adopt, or options, rights or warrants which entitle the
         Trustee to subscribe to or purchase securities, so long as the
         investments are made in accordance with the laws of the state of the   
         situs of the Trust and the terms of this agreement.

         When the Trustee receives funds to be invested or determines that
         assets in the Trust fund should be sold and the proceeds held for a
         period of time pending reinvestment or other purpose, the funds may be
         held uninvested in cash or invested in short-term investments such as
         certificates of deposit with the Trustee, U.S. Treasury bills, savings
         accounts with the Trustee, commercial paper or other similar assets
         which may be offered by the Trustee and as may be determined by the
         Trustee in its sole discretion.

         Notwithstanding the first paragraph of this section, if there is a
         Change of Control, all funds deposited prior to the Change of Control
         are to be invested solely in U.S. Treasury obligations which mature in
         three years or less unless there have been insurance policies
         contributed to or purchased by the Trust prior to the Change of
         Control in which event they shall be transferred to Corporation for a
         corporation contribution in the amount of their terminal reserve value
         plus cash surrender value, if any, and if Corporation elects not to
         purchase said policies, the policies shall be distributed to the
         insured Participant.

         requirements of Sections 4.1 and 4.2, the following powers, duties and

         it because of a direction of the Committee, Corporation or agent
         appointed by either of them except to the extent required by any
         applicable state or federal law, which liability cannot be waived.
         When the Trustee has made any payment out of the Trust fund at the
         direction of the Committee, Corporation or any agent appointed by
         either of them, it will not be responsible for the correctness of the
         amount of the payment to the recipient, or the method by which it is
         paid.  The Trustee is also protected in relying upon any certificate,
         notice, resolution, consent, order, or other communication purporting
         to have been signed on behalf of the Committee, Corporation or an
         agent appointed by either of them which it believes to be genuine,
         without any obligation on the part of the Trustee to ascertain whether
         or not the provisions of this agreement are being fulfilled.

7.3      INDEMNIFICATION OF TRUSTEE.  The Trustee shall be indemnified and held
         harmless from any loss, liability, claim cost or expense (including
         attorney fees, court costs, and other costs in defending a lawsuit)
         arising out of its acting as Trustee of the Trust except for bad faith
         or gross negligence.  The Trustee 
   10
                                                                         Page 10



         shall not be liable for the actions of any other fiduciary or the
         failure of any other fiduciary to take action in a given situation.

7.4      TRUSTEE'S POWER TO WITHHOLD FOR PAYMENT OF TAXES.  The Trustee may, in
         its sole discretion, withhold from distribution all or any part of the
         fund which the Trustee considers necessary and proper for the payment
         of taxes under present or future laws, which the Trustee is obligated
         to pay or withhold.

7.5      TRUSTEE NOT REQUIRED TO PREPARE RETURNS OR REPORTS.  The Trustee will
         not be required to prepare, file, or distribute any tax return or
         other report required by a governmental agency under state or federal
         law.  All such returns or reports shall be the obligation of
         Corporation.

7.6      WHEN DETERMINING COURSE OF ACTION TRUSTEE MAY RELY UPON COMMITTEE.  If
         at any time the Trustee is in doubt concerning the course which it
         should follow in connection with any matter relating to the
         administration of the Trust, it may request the advice of the
         Committee and be protected in relying upon the written advice or
         direction given by the Committee except during any four-year period
         beginning on the day a Change of Control occurs.  During any such
         period the Trustee may not request and rely on the advice of the
         Committee.
        

                                  ARTICLE VIII

                   SETTLEMENT OF THE ACCOUNTS OF THE TRUSTEE

8.1      TRUSTEE'S MAINTENANCE OF RECORDS.  The Trustee will keep all records
         necessary in the conduct of the Trust.  The Trustee's books and
         records of the Trust fund are open to inspection by the Committee,
         Corporation and/or the Participants at all reasonable times during
         business hours of the Trustee.

8.2      TRUSTEE'S RENDERING OF ACCOUNTING TO COMMITTEE.  Within 60 days after
         the close of each Plan Year, or such other times as requested by the
         Committee and as of the date of the removal or resignation of the
         Trustee, the Trustee must render to the Committee an accounting and
         report of the Trust fund for the Plan Year or other period that is
         applicable since the previous accounting.  The report is to reflect
         the transactions for the period covered, the cost of assets and
         investments, the fair market value of the assets held in the Trust and
         the amount held for the funding of Corporation's obligation to the
         Participants as of the end of the Plan Year or such other date as is
         applicable.  The report is to be open for inspection for 90 days after
         its receipt by the Committee, and if objections are not filed within
         that period of time, it is 
   11
                                                                         Page 11


         assumed that the report is approved.  That approval will constitute a
         full and complete discharge and release to the Trustee by Corporation,
         all of the Participants and all other persons having or claiming any
         interest in any of the Trust fund.


                                   ARTICLE IX

            ACTION, RESIGNATION, REMOVAL AND SUBSTITUTION OF TRUSTEE

9.1      APPOINTMENT OF TRUSTEE AND OPERATION IF MULTIPLE TRUSTEES.  One or
         more entities or one or more individuals will serve as Trustee, as
         determined from time to time by the members of the Board of Directors
         who are not eligible to participate in the Plan.  When more than one
         entity and/or individual serves as Trustee, any action by the Trustees
         will be determined by the majority of the Trustees.  Those actions
         will be binding upon all parties at interest.  The entities and/or
         individuals who collectively act as Trustee may act by vote at a
         meeting or by a written consent without a meeting.  Any act of more
         than one individual or entity serving as Trustee will be sufficiently
         evidenced if certified to by one of the individuals or entities
         serving as Trustee.  Also, if there is more than one individual and/or
         entity serving as Trustee, one of the Trustees may be given authority
         to perform all administrative and ministerial duties.  Any individual
         who serves as Trustee may be an employee of Corporation.  Each Trustee
         will serve until a successor Trustee is named by the members of the
         Board of Directors who are authorized to appoint the Trustee or until
         his death or incapacity or his or its resignation or removal, in which
         event the members of the Board of Directors who are authorized to
         appoint the Trustee will name a successor Trustee.

9.2      RESIGNATION OF TRUSTEE.  The Trustee or any successor Trustee may
         resign as Trustee at any time by filing with Corporation its or his
         written resignation.  No resignation will take effect until 60 days
         from the date of notice unless prior to that time a successor Trustee
         has been appointed and he or it has accepted the office.

9.3      REMOVAL OF TRUSTEE.  The Trustee or any successor Trustee may be
         removed by Corporation at any time.  No removal will take effect until
         60 days from the date of notice unless prior to that time a successor
         Trustee has been appointed and he or it has accepted the office and
         the Trustee consents to the earlier date.
   12
                                                                         Page 12


9.4      NO VACANCY IN OFFICE OF TRUSTEE.  Any vacancy in the office of Trustee
         created by the resignation or removal of the Trustee will not
         terminate the Trust.  Upon removal or resignation of the Trustee, the
         members of the Board of Directors who are authorized to appoint the
         Trustee must appoint a successor Trustee.

9.5      APPOINTMENT OF SUCCESSOR TRUSTEE.  The appointment of a successor
         Trustee will be accomplished by the delivery to the resigning or
         removed Trustee, as the case may be, of a written appointment of the
         successor Trustee by the members of the Board of Directors who are
         authorized to appoint the Trustee and the written acceptance of the
         appointment by the successor Trustee.  Any successor Trustee must be
         one or more individuals (who may be employees of Corporation) or an
         entity authorized and empowered to conduct a trust business in the
         state of the situs of the Trust.  This agreement will then be
         applicable to each successor Trustee.

9.6      APPOINTMENT OF SUCCESSOR TRUSTEE AFTER A CHANGE OF CONTROL.  If a
         Trustee dies, becomes incapacitated, resigns or is removed
         contemporaneously with or following a Change of Control,
         notwithstanding anything to the contrary in this agreement, the
         members of the Board of Directors who are authorized to appoint the
         Trustee must receive the consent of a majority in interest of the
         Participants for whose account assets are held under the terms of this
         agreement in order to appoint a successor Trustee.  If the members of
         the Board of Directors who are authorized to appoint the Trustee
         cannot obtain the consent of a majority in interest of the
         Participants to any Trustee acceptable to them, then an arbitrator
         will be appointed to select the new Trustee which will be appointed by
         the members of the Board of Directors who are authorized to appoint
         the Trustee.  The arbitrator will be selected by permitting each of
         Corporation and the Participants (by a vote of the majority in
         interest) to strike one name each from a panel of three names obtained
         from the American Arbitrator Association.  The person whose name is
         remaining will be the arbitrator.

9.7      VESTING OF RIGHTS, TITLES, POWERS IN SUCCESSOR TRUSTEE.  Any successor
         Trustee, after acknowledging acceptance of this agreement, the Trust
         assets and the accounting of the retiring Trustee, will be vested with
         all the estates, titles, rights, powers, duties, and discretions
         granted to the retiring Trustee.  The retiring Trustee must execute
         and deliver all assignments or other instruments necessary or
         advisable for the transfer of all Trust assets as are reasonably
         required by the successor Trustee.

9.8      CONTINUANCE OF CORPORATE TRUSTEE THROUGH MERGER.  Any corporation into
         which any corporate Trustee or any successor corporate Trustee may be
   13
                                                                         Page 13


         merged or consolidated, or any corporation resulting from any merger
         or consolidation to which any corporate Trustee or any successor
         corporate Trustee may be a party, or any corporation to which all or
         substantially all of the trust business of any corporate Trustee or
         any successor corporate Trustee may be transferred, will be a
         successor of such Trustee under this agreement without the filing of
         any instrument or the performance of any other act.


                                   ARTICLE X

                           AMENDMENT AND TERMINATION

10.1     CORPORATION'S RIGHT TO AMEND.  The members of the Board of Directors
         who are not eligible to participate in the Plan will have the sole
         right to amend this agreement.  An amendment must be made by an
         executed written agreement setting forth the nature of the amendment
         and its effective date.  No amendment will make this agreement nor the
         Trust created by this agreement revocable or will divert the funds
         held in the Trust created by this agreement from the purposes set out
         in Section 2.2.  No amendment will change a Participant's rights under
         any provision of this Trust after a Change of Control has occurred,
         without the affected Participant's consent, as to assets contributed
         to the Trust before the Change of Control and as to the accumulation
         of income and appreciation applicable to those assets.  No amendment
         will increase the duties of the Trustee without its written consent.

10.2     AMENDMENTS NECESSARY TO COMPLY WITH STATE OR FEDERAL STATUTES.
         Corporation agrees to make any amendment to this agreement as may be
         necessary to maintain compliance with the various federal and state
         laws and any amendment may be made retroactively.

10.3     TERMINATION OF TRUST BY CORPORATION.  The members of the Board of
         Directors who are not eligible to participate in the Plan may
         terminate the Trust only after all benefits to the extent funded by
         the Trust have been paid to the Participants who are funded by it,
         pursuant to the Plan, by executing and delivering to the Trustee a
         notice of termination which specifies the date on which the Trust will
         terminate.  Upon termination, the Trustee will distribute to the
         Participants the assets certified to it by the Committee to be
         sufficient to fulfill all of the obligations of Corporation under the
         Plan at the time and in the form provided in it, and afterward, any
         Trust assets remaining will be allocated among the Participants in the
         ratio of each Participant's Account to the total value of all
         Participant Accounts.  The Trust created under this agreement will
         automatically terminate upon a determination of the insolvency of
         Corporation.
   14
                                                                         Page 14

         In that event, the Trustee shall deliver the Trust assets as directed
         by a court of competent jurisdiction.  The Trust may also be
         terminated by Corporation, with the written consent of all of the
         Participants whose benefits are funded by it, if a tax, labor or other
         federal statute or regulation causes this Trust to become taxable,
         before distribution, to the Participant or to become unlawful.  In
         that event, the Trustee will return the assets to the Corporation.

10.4     CONTINUANCE OF TRUST WHEN CORPORATION CONSOLIDATES, MERGES OR
         SELLS SUBSTANTIALLY ALL OF ITS ASSETS.  The Trust created by this
         agreement will not terminate in the event Corporation consolidates or
         merges and is not the surviving corporation, sells substantially all
         of its assets, is a party to a reorganization in which its employees
         and substantially all of its assets are transferred to another entity,
         liquidates or dissolves if there is a successor corporation.  Instead,
         the Trust will continue until it has fulfilled the obligations to its
         Participants as set forth in Section 2.2, at which time it will        
         automatically terminate.


                                   ARTICLE XI

                                 MISCELLANEOUS

11.1     NO EMPLOYMENT COMMITMENT.  The adoption and maintenance of the Trust
         created under this agreement will not be deemed to be a contract
         between Corporation and the Participants which gives the Participants
         the right to be retained on the Board of Directors of Corporation, to
         interfere with the rights of Corporation to remove the Participants,
         or to interfere with the Participants' rights to terminate their
         membership on the Board of Directors at any time.

11.2     NON-ALIENATION OF BENEFITS.  No benefits payable or to become payable
         from the Trust will be subject to anticipation or assignment by the
         Participants or other persons entitled to receive benefits under the
         Trust; to attachment by, interference with, or control of any
         creditors of the Participants or other persons entitled to receive
         benefits under the Trust; or to being taken or reached by any legal or
         equitable process in satisfaction of any debt or liability of the
         Participants prior to their actual receipt by the Participants or
         other persons entitled to receive benefits under the Trust.  Any
         attempted conveyance, transfer, assignment, mortgage, pledge, or
         encumbrance of the Trust, any part of it, or any interest in it by a
         Participant, or any person entitled to secure benefits under the
         Trust, prior to distribution will be void, whether that conveyance,
         transfer, assignment, mortgage, pledge or encumbrance is intended to
         take place or become effective before or after any distribution of
   15
                                                                         Page 15


         Trust assets or the termination of the Trust fund itself.  The Trustee
         will never under any circumstances be required to recognize any
         conveyance, transfer, assignment, mortgage, pledge or encumbrance by a
         Participant, or other person entitled to receive benefits under the
         Trust created under this agreement, of a Trust fund created under this
         agreement, any part of it, or any interest in it, or to pay any money
         or thing of value to any creditor or assignee of a Participant, or
         other person entitled to receive benefits under the Trust, for any
         cause whatsoever.

11.3     GENDER AND NUMBER OF WORDS.  Whenever the context requires it, words
         of the masculine, feminine or neuter gender will include one or both
         of the others; and words used in either the singular or the plural
         number will include the other.

11.4     TEXAS LAW APPLICABLE.  The provisions of this agreement shall be
         construed, according to the laws of the state of Texas.

11.5     SEVERABILITY OF AGREEMENT.  Each provision of this agreement is
         severable, and if any provision is found to be void or against public
         policy, it will not affect the validity of any other provision hereof.

11.6     DEFINITIONS.  Any word not otherwise defined in this agreement shall
         have the meaning as defined in the Plan.

         IN WITNESS WHEREOF, Corporation and the Trustee have executed this
agreement on this 23rd day of February 1995.
