        Association Contract (the "OPON Contract") dated July 15, 1987 by and
        between ODC and Empresa Colombiana de Petroleos ("ECOPETROL") (the
        present calculation of the amount of the Interest being subject to the
        right of ECOPETROL to reacquire a fifty percent (50%) interest in the
        OPON Contract); and 

             WHEREAS, Alliance is the sole beneficial owner of the Interest
        being held by ODC, under that certain Compensation/Settlement Agreement
        dated October 17, 1990, by and among Purchaser, Hondo Oil & Gas Company,
        a Delaware corporation ("Hondo"), Jim C. Roth ("Roth"), International
        Exploration Advisors ("International"), Gary D. Bell ("Bell"), Alliance
        and ODC and certain oral agreements between ODC and Alliance
        (collectively, the "Compensation/Settlement Agreement"); and

             WHEREAS, at the time of execution of the Compensation/Settlement
        Agreement certain parties were listed collectively, without further
        allocation among them, as co-recipients of the interests conveyed
        pursuant to that agreement, including Roth, individually and as managing
        partner of International, an entity described in the
        Compensation/Settlement Agreement as a partnership, Bell, individually,
        and Alliance Petroleum International, an entity described in the
        Compensation/Settlement Agreement as a partnership and, subsequent to
        the execution of that Compensation/Settlement Agreement, it was
        clarified that International was never formally established and that
        Alliance Petroleum International was actually formed as a Texas
        corporation; and

             WHEREAS, Roth and Bell acknowledge and represent that no portion of
        the Interest was accepted or held by International at any time and that
        any portions of the Interest to which Roth and Bell may have
        individually been entitled to take ownership were transferred to and
        held as assets of Alliance of which they were and are the sole
        shareholders; and

             WHEREAS, Purchaser separately owns an interest in the OPON Contract
        and desires to increase its interest therein by acquiring the Interest
        from ODC and Alliance; and

             WHEREAS, Alliance desires to sell and assign its beneficial
        interest to Purchaser and in connection therewith ODC desires to assign
        the Interest to Purchaser, and Alliance desires to receive as
        consideration therefore, freely trading common stock of Hondo; and










             WHEREAS, Hondo is agreeable to the issuance of its common stock in
        accordance with the terms and conditions hereof in order to facilitate
        the acquisition of the Interest by Purchaser, which Hondo deems to be in

        the receipt and sufficiency of which are hereby acknowledged, and in
        consideration of the mutual promises, covenants, representations, and
        warranties herein contained, the parties hereto agree as follows: 

                                       ARTICLE I

                                      THE INTEREST
                                     --------------
             1.1  Purchase and Delivery of the Interest.  Upon the basis of the
        representations and warranties and on the terms and subject to the
        conditions set forth in this Agreement, Alliance hereby agrees to sell

                                       ARTICLE II

                                     CONSIDERATION
                                     --------------
             As consideration of the sale by Alliance and the delivery of the
        Interest to Purchaser by ODC as provided in Article I hereof, Purchaser
        shall cause Hondo to issue to Alliance at the Closing, such number of
        shares (the "Shares") of Common Stock, $1.00 par value in Hondo (the
        "Hondo Stock") as shall be equivalent to EIGHT HUNDRED EIGHTY EIGHT
        THOUSAND SEVEN HUNDRED FIFTY DOLLARS (U.S. $888,750) (the "Sales Price")
        based upon the closing price on the American Stock Exchange ("AMEX") of
        such Hondo Stock on the business day immediately prior to the later of
        (i) the effective date (the "Effective Date") of the Registration
        Statement (as hereinafter defined) as declared by The United States
        Securities and Exchange Commission (the "Commission") or (ii) the date
        (the "AMEX Approval Date") AMEX approves the listing of the Shares on
        its exchange pursuant to an Additional Listing Application (the
        "Additional Listing Application") to be filed by Hondo.  Provided,
        however, in no event shall the number of the Shares exceed (and in no
        event shall Hondo be required to issue to Alliance more than) sixty-five
        thousand (65,000) shares of Hondo Stock.  In the event that upon the
        later of the Effective Date of such Registration Statement or the AMEX
        Approval Date, Hondo would otherwise be required to issue more than
        sixty-five thousand (65,000) shares of Hondo Stock as the  Shares in
        order to satisfy the Sales Price, Alliance shall have the right, solely
        and without the joinder of ODC, to (i) terminate this Agreement upon
        written notice to Purchaser and ODC, whereupon the transactions
        contemplated hereunder shall be void and of no further force and effect,

                                          -2-









        or (ii) accept such sixty-five thousand (65,000) shares of Hondo Stock
        as the  Shares in full satisfaction of the Sales Price hereunder. 
        Provided, however, in the event that at any time after the date of this
        Agreement and prior to the Closing, the closing price of the Hondo Stock
        on AMEX is Thirteen and 625/1000 Dollars (U.S.$13.625) or less for five
        (5) consecutive business days, then Alliance shall have the right to
        terminate this Agreement upon written notice to Purchaser and the
        transactions contemplated hereunder shall be void and of no further
        force and effect.  The Sales Price shall be paid in shares of Hondo
        Stock only, in no event shall the Purchaser be obligated to pay the
        Sales Price in cash or any other funds whatsoever.  The parties
        acknowledge and agree that no portion of the Sales Price shall be
        payable to ODC.

                                      ARTICLE III

                            -------------------------------
             Upon execution of this Agreement, Purchaser shall be obligated to
        cause Hondo to (i) prepare and file with the Commission a registration
        statement on an appropriate form, together with all necessary amendments
        thereto, with respect to the Shares (the "Registration Statement") as
        soon as is reasonably possible; (ii) use its best efforts to cause such
        Registration Statement to become effective as soon as is reasonably
        possible and to remain effective; and (iii) perform such other actions
        as shall be necessary to issue and deliver such Shares to Alliance,
        including, but not limited to, preparing and delivering as soon as is
        reasonably possible the Additional Listing Application to AMEX. 
        Purchaser shall provide Alliance courtesy copies of all materials that
        are otherwise publicly available which relate to the Registration
        Statement or the Additional Listing Application and which are filed with
        the Commission and/or AMEX.

                                       ARTICLE IV

                                        CLOSING

                       extent that they arise out of or result from any

                       of the Interest following the Closing, but only to the
                       extent that they arise out of or result from any

                  8.3  Cooperation of Parties.  The parties hereto shall
        reasonably, diligently, and in good faith, cooperate with each other in
        connection with the investigation, accounting, disposition, or payment
        of any matter reasonably believed to give rise to a right of
        indemnification under Section 8.1 or 8.2 of this Agreement.  

                                       ARTICLE IX

                                     MISCELLANEOUS
                                     -------------
             9.1  Expenses.  Each of the parties shall pay its own costs and
        expenses, including attorney's and accounting fees, incurred by such
        party or for such party s benefit in connection with the negotiation,
        preparation, consummation and performance of this Agreement and the
        transactions provided for herein.  Alliance shall continue to be
        responsible for all billings and administrative expenses related to the
        Interest due to ODC with respect to periods or actions prior to the
        Closing.  Alliance shall pay at or prior to the Closing, any and all
        outstanding administrative expenses or other obligations related to the
        Interest which are otherwise due to ODC in connection with the ownership
        of the Interest prior to the Closing subject to normal industry auditing
        procedures.

             9.2  Survival of Representations.  Notwithstanding any
        investigation made by or on behalf of a party or parties, all
        representations, warranties, and covenants made by the parties each to
        the other in this Agreement or pursuant hereto shall survive the Closing
        and the consummation of the transactions contemplated by this Agreement.


             9.3  No Assignment.  This Agreement shall not be assigned by any
        party hereunder, the parties' intention hereunder being to reflect that
        the Purchaser's obligation to cause the Hondo Stock to be delivered to
        Alliance shall be personal to Alliance only and that Alliance's and
        ODC's obligation to assign and deliver the Interest hereunder shall be
        personal to the Purchaser only.  Accordingly, neither ODC nor Alliance
        shall assign or deliver the Interest (or any portion thereof) to any
        party other than Purchaser prior to the Closing or earlier termination
        of this Agreement.

             9.4  Entire Agreement.  This Agreement and any documents executed
        or delivered by the parties pursuant to this Agreement, constitute the
        entire understanding and agreement of the parties hereto and supersede
        all other prior agreements and understandings, written or oral, between
        the parties.  

             9.5  Further Instruments.  The parties hereto will, upon execution
        of the Agreement or any time thereafter, deliver and/or execute such
        further instruments as may reasonably be requested by the other party
        which are necessary or appropriate with respect to the consummation of
        the transactions contemplated by this Agreement.  None of the documents
        or instruments requested hereunder shall contain an undertaking or
        representation inconsistent with the undertakings and representations
        contained in this Agreement.
