         still owned by the Company (collectively, the "Fee Property").  Except

         indefeasible title to the Fee Property, free of any mortgage, pledge,
         lien, charge, encumbrance or other adverse claim and there are no
         outstanding opinions or rights of first refusal to purchase any of the

         Financial Statements as of the Statement Date, or purported to have
         been acquired by the Company after such date or used in connection

         in Schedule 2.7(a), there is no other real property, buildings or
         facilities owned, used or occupied by Company.

         or any affiliate of Seller or SBJ Trust has any rights whatsoever.
         Except for the provisions of Sections 2.7(b) and 4.9 and any other
         provision referring to such section or compliance therewith, for the
         purposes of this Agreement, all of the representations, warranties and

         owned by any Seller or any affiliate thereof.

         the Company.

                 (c)      There is no pending or, to the best of Sellers'
         knowledge, threatened condemnation or similar proceeding or special
         assessment affecting any Real Property, or any part thereof, nor has
         any Seller or the Company received notification that any such
         proceeding or assessment is contemplated by any Governmental
         Authority.  Neither (i) the location, occupancy, operation or use of
         any Real Property (including the buildings, improvements, fixtures and
         equipment forming a part thereof) nor (ii) the construction of any
         Real Property violates any applicable law, statute, ordinance, rule,
         regulation, order or





                                       4
<PAGE>   5
         determination of any Governmental Authority or any board of fire
         underwriters (or other body exercising similar functions), or any
         restrictive covenant or deed restriction (recorded or otherwise)
         affecting any of the Real Property, including, without limitation, all
         applicable zoning ordinances and building codes, flood disaster laws
         and health laws and regulations (hereinafter sometimes collectively
         called "Applicable Laws").

                 (e)      No Real Property is within any area determined by the
         Department of Housing and Urban Development to be flood prone under
         the Federal Flood Disaster Protection Act of 1973.

                 (f)      (i) There are no unpaid and presently due charges,
         debts, liabilities, claims or obligations arising from the
         construction, occupancy, ownership, use or operation of any Real
         Property, or the business operated thereon, that could give rise to
         any mechanic's or materialmen's or other statutory lien (A) against
         such Real Property or any part thereof (including any Real Property
         estate therein), or (B) for which the Company will be responsible, and
         (ii) the Company has not entered into any agreement the performance of
         which could give rise to a lien or other encumbrance against the Real
         Property.

                 (g)      There exists no action or proceeding to modify or
         terminate the present zoning, if any, of any Real Property.

                 (h)      There exists no judicial, quasi-judicial,
         administrative or other proceeding or court order, building code
         provision, deed restriction or restrictive covenant (recorded or
         otherwise) or other private or public limitation that to the best of
         Sellers' knowledge could in any way impede or adversely affect the use
         of such Real Property by the Company as currently used.

                 (i)      Each Real Property is connected to and serviced by
         water, septic tank or sewage disposal (as applicable), gas, telephone
         and electric facilities that are adequate for current use of such Real
         Property and is in compliance with all Applicable Laws.  All public
         utilities required for the operation of such Real Property enter such
         Real Property through adjoining public streets or, if they pass
         through adjoining private land, do so in accordance with valid public
         easements.  Each Real Property abuts on and has direct vehicular
         access to a public road, or has access to a public road via a
         permanent, irrevocable appurtenant easement.

                 (j)      To the best of Sellers' knowledge there is not any
         (A) change contemplated in any Applicable Laws, (B) judicial or
         administrative action, (C) action by adjacent landowners, (D)
         administrative action, (E) natural or artificial conditions upon such
         Real Property, or (F) significant adverse fact or condition relating
         to such Real Property or its current use by the Company, that would
         prevent, limit, impede or render more costly the Company's use of such
         Real Property.

                 (k)      Permanent certificates of occupancy, all licenses,
         permits, authorizations and approvals required by all governmental
         authorities having jurisdiction, and the requisite certificates of the
         local board of fire underwriters (or other body exercising similar
         functions)





                                       5

         have been issued for such buildings and improvements constituting a
         part of each Real Property and have been paid for and all of the
         foregoing are in full force and effect.

                 (l)      Each Real Property, including building and
         improvements, is in good condition and repair.  The equipment and
         other personal property used in connection with the Company's business
         and operations (i) is in good condition and repair, subject only to
         normal wear and tear, (ii) is free of any patent structural defects or
         (to the best of Seller's knowledge) latent structural defects, (iii)
         is suitable for the purpose for which it is presently used, and (iv)
         has been maintained in accordance with industry practice and
         manufacturer's recommended guidelines.

                 (m)      No commitments have been made by the Company, any
         Seller or other person to any Governmental Authority, utility company,
         school board, church or other religious body, or any homeowners or
         homeowners' association, or any other organization, group or
         individual, relating to any Real Property that would impose an
         obligation upon the Purchaser or its successors or assigns to make any
         contribution or dedication of money or land or to construct, install
         or maintain any improvements of a public or private nature on or off
         such Real Property.  Each Real Property's compliance with all
         Applicable Laws does not depend on, and no zoning, subdivision or
         other governmental approval for such Real Property depends on, any
         Real Property, or rights appurtenant thereto, other than such Real
         Property.  No Governmental Authority has imposed any requirement that
         any developer of any Real Property pay directly or indirectly any
         special fees or contributions or incur any expenses or obligations in
         connection with any development of such Real Property or any part
         thereof.  The provisions of this subparagraph shall not apply to any
         regular or nondiscriminatory local real estate or school taxes
         assessed against any such Real Property.

                 (n)      Each of the Leases is valid and subsisting and in
         full force and effect in accordance with its terms, provisions and
         conditions and constitutes the legal, valid, binding and enforceable
         obligation of the Company and the landlord thereunder; no party
         thereto is in default thereunder and no event has occurred that, with
         notice or lapse of time or both, would constitute a default; all
         initial installation work, if any, has been fully performed, paid for
         and accepted.  No landlord has given any notice to the Company or
         Sellers of intention of instituting litigation with respect to any
         Lease.  True, complete and correct copies of each of the Leases as
         currently in effect have been delivered to the Purchaser, and the
         Company is not subject to any obligation to or for the benefit of the
         landlord with respect any of the related Real Property except as fully
         set forth in such Leases.

         2.8     Litigation, Judgments, Etc.  Except as fully described in
Schedule 2.8, there are no actions, suits, proceedings or investigations
pending or, to the best of Sellers' knowledge, threatened against or affecting
the Company or its assets in any court or before or by any federal, state or
other Governmental Authority, or before any arbitrator, and the Sellers have no
reason to believe that any such action, suit, proceeding or investigation will
be brought or threatened against the Company or its assets.  Each of the
incidents giving rise to the matters listed on Schedule 2.8 is fully covered by
insurance (subject only to the applicable deductibles described on Schedule
2.22), is being defended by the applicable insurance carrier and its counsel,
and no such insurance carrier has given the Company notice of any reservation
of rights with respect to any of the foregoing.  The Company is not in default
with respect to any judgment, order, writ, injunction, decree or award
applicable to it





                                       6
<PAGE>   7
of any court or other Governmental Authority or arbitrator having jurisdiction
over it and all such judgments, orders, writs, injunctions, decrees and awards
are described in Schedule 2.8.  Except as fully described in Section 2.10,
Section 2.12, Section 2.13 or in any disclosure schedule related thereto, the
Company is not in default with respect to any rule or regulation applicable to
it of any Governmental Authority having jurisdiction over it, or in violation
of any law or statute.

         2.9     Intellectual Property.

                 (a)      Marks.  Schedule 2.9(a) lists all foreign and
         domestic trademarks, service marks, trade dress, and trade names
         (collectively, the "Marks"), and registrations therefor, used by
         Company in connection with the conduct of business now being
         conducted.  Except as disclosed in Schedule 2.9(a) Company is the sole
         owner of all right, title and interest in the Marks and, to the best
         of Sellers' knowledge, there exist no facts that would invalidate the
         Marks in the areas in which business is presently being conducted.
         Except as disclosed on Schedule 2.9(a), to the best of Sellers'
         knowledge, the Marks, as currently being used, do not infringe upon
         any rights of a third party.  Neither the Company nor any Seller has
         received notice from a third party asserting that one or more of the
         Marks are infringing, or would infringe if used in a geographic area
         outside the area in which the Company's business is presently
         conducted.  Except as disclosed on Schedule 2.9(a), to the best of
         Sellers' knowledge, there are no third party uses of the Marks or
         colorable imitations thereof.  Neither the Company, any Seller or any
         of their affiliates, nor, to the best of Sellers' knowledge, any other
         person has granted any rights or license whatsoever with respect to
         the use of the Marks "Tortilla King" or "El Rey" or any derivation
         thereof, or any other.  Except as set forth on Schedule 2.9(a),
         neither any Seller nor any affiliate of the Company has any rights or
         license with respect to any of the Marks.  Any rights or licenses that
         any Seller or any affiliate of the Company has will be transferred to
         the Company at or prior to the Closing for no additional
         consideration.  No rights in any of the Marks listed in Schedule
         2.9(a) will be affected in any way by virtue of the execution of this
         Agreement or the consummation of the transactions contemplated hereby.
         No Mark is the subject of any pending, or to the best of Sellers'
         knowledge, threatened, litigation, arbitration, interference or
         protest proceeding.

the terms "hazardous substance" and "release" (or "threatened release") have
the meanings specified in CERCLA, and the terms "solid waste" and "disposal"
(or "disposed") have the meanings specified in RCRA; provided, however, that to

         delivered by or on behalf of any party hereto pursuant to or in
         connection with this Agreement for the purposes of this Agreement
         shall be deemed to be representations and warranties hereunder.
         Except to the extent otherwise provided in paragraph (b) below, the

         respect to a bona fide claim asserted with respect thereto prior to
         such date in accordance with the terms of Section 7.2.

         7.2     Indemnification.

                 (a)      Indemnification by Sellers for Claims Relating to
         Occurrences or Conditions Prior to Closing.  Sellers jointly and
         severally agree to defend, indemnify, protect, save and hold harmless
         the Purchaser, the Company, and their affiliates, successors, assigns,
         officers, directors and controlling persons (collectively, the
         "Purchaser Indemnitees") from and against any and all demands, claims,

         costs and expenses, including, without limitation, litigation costs
         and all attorneys'





                                       26
<PAGE>   27
         and experts' fees and expenses (collectively, the "Losses") relating
         to (i) the ownership, condition, operation or conduct of the business

         and hold harmless the Purchaser Indemnitees from and against any and
         all Losses asserted against, resulting from, imposed upon or incurred
         by any of the Purchaser Indemnitees by, or arising out of, or as a
         result of, any of the representations, warranties, covenants or
         agreements of Sellers or the Company contained in this Agreement or
         any certificate or instrument delivered by any Seller or the Company
         pursuant to the terms hereof being incorrect, untrue or breached.
         Subject to the foregoing, the Purchaser Indemnitees shall have the
         right to indemnification under this Section 7.2(b) in accordance with
         its terms, regardless of whether any of them could alternatively
         receive indemnification with respect thereto under Section 7.2(a)(i).
         The Purchaser agrees to defend, indemnify and hold harmless the Seller
         Indemnitees from and against any and all Losses asserted against,
         resulting from, imposed upon or incurred by any of the Seller
         Indemnitees by, or arising out of, or as a result of, any of the
         representations, warranties, covenants or agreements of the Purchaser
         contained in this Agreement or any certificate or instrument delivered
         by the Purchaser pursuant to the terms hereof being incorrect, untrue
         or breached.  Subject to the foregoing, the Seller Indemnitees shall
         have the right to indemnification under this Section 7.2(b) in
         accordance with its terms, regardless of whether any of them could
         alternatively receive indemnification with respect thereto under
         Section 7.2(a)(ii).  Notwithstanding the foregoing provisions of this
         clause (b), Sellers and/or the Purchaser shall have liability pursuant
         to this Section 7.2(b) arising out of representations and warranties
         being incorrect or untrue or covenants or agreements breached only
         with respect to Losses arising out of or as a result of a breach or
         untruth described in a Claim Notice given to Sellers or the Purchaser,
         respectively, in accordance with the provisions hereof on or prior to
         the applicable Termination Date, if any.

                 (c)      Express Negligence Acknowledgment.  Without limiting
         or enlarging the scope of the indemnification obligations set forth in
         this Agreement, AN INDEMNIFIED PARTY WILL BE ENTITLED TO
         INDEMNIFICATION IN ACCORDANCE WITH THE TERMS OF THIS AGREEMENT
         REGARDLESS OF WHETHER THE LOSS GIVING RISE TO SUCH INDEMNIFICATION
         OBLIGATION IS THE RESULT OF THE SOLE, CONCURRENT, OR COMPARATIVE
         NEGLIGENCE, FAULT, OR STRICT LIABILITY OF SUCH INDEMNIFIED PARTY.

                 (d)      Assertion of Claims.  All claims for indemnification
         by any of the Seller Indemnitees or any of the Purchaser Indemnitees
         under Section 7.2(a) or any other provision of this Agreement or any
         Document shall be asserted and resolved as follows:

                          (i)     Any person claiming indemnification hereunder
                 is hereinafter referred to as the "Indemnified Party" and any
                 person against whom such claims are asserted hereunder is
                 hereinafter referred to as the "Indemnifying Party."  In the
                 event that any Losses are asserted against or sought to be
                 collected from an Indemnified Party by a third party, said
                 Indemnified Party shall with reasonable promptness and in
                 writing notify the Indemnifying Party of the Losses,
                 specifying the nature of and specific





                                       27
<PAGE>   28
                 basis for such Losses and the indemnity claim and the amount
                 or the estimated amount thereof to the extent then feasible
                 and enclosing a copy of all papers (if any) served with
                 respect to the claim (the "Claim Notice").  The Indemnifying
                 Party shall not be obligated to indemnify the Indemnified
                 Party with respect to any such Losses if the Indemnified Party
                 fails to notify the Indemnifying Party thereof in accordance
                 with the provisions of this Agreement in reasonably sufficient
                 time so that the Indemnifying Party's ability to defend
                 against the Losses is not prejudiced, but only to the extent
                 such notification within such time period is practicable.  The
                 Indemnifying Party shall have 30 days from the date the Claim
                 Notice is given in accordance with the notice provisions
                 hereof (the "Notice Period") to notify the Indemnified Party
                 (x) whether it disputes the liability of the Indemnifying
                 Party to the Indemnified Party hereunder with respect to such
                 Losses and (y) whether it desires, at the sole cost and
                 expense of the Indemnifying Party, to defend the Indemnified
                 Party against such Losses; which election to defend may be
                 made without prejudicing the Indemnifying Party as to its
                 liability hereunder, other than with respect to the costs of
                 defense.  Notwithstanding the foregoing, any Indemnified Party
                 is hereby authorized prior to and during the Notice Period to
                 file any motion, answer or other pleading that it shall deem
                 necessary or appropriate to protect its interests or those of
                 the Indemnifying Party (and of which it shall have given
                 notice and opportunity to comment to the Indemnifying Party)
                 and that is not prejudicial to the Indemnifying Party.  (A) In
                 the event that the Indemnifying Party notifies the Indemnified
                 Party within the Notice Period that it desires to defend the
                 Indemnified Party against such Losses and except as
                 hereinafter provided, the Indemnifying Party shall have the
                 right to defend by all appropriate proceedings, and with
                 counsel of its own choosing, which proceedings shall be
                 promptly settled or prosecuted by them to a final conclusion.
                 If the Indemnified Party desires to participate in, but not
                 control, any such defense or settlement it may do so at its
                 sole cost and expense.  If requested by the Indemnifying
                 Party, the Indemnified Party agrees to cooperate with the
                 Indemnifying Party and its counsel in contesting any Losses
                 that the Indemnifying Party elects to contest, or, if
                 appropriate and related to the claim in question, in making
                 any counterclaim against the person asserting the third party
                 Losses, or any cross-complaint against any person.  No claim
                 with respect to which the Indemnifying Party has admitted its
                 liability may be settled or otherwise compromised without the
                 prior written consent of the Indemnifying Party.  Any party
                 settling or compromising a claim in violation of the preceding
                 sentence shall be solely liable for the amount of the
                 settlement or compromise.  (B)  If the Indemnifying Party does
                 not notify the Indemnified Party within 30 days after the
                 receipt of a Claim Notice that it elects to undertake the
                 defense thereof, the Indemnified Party shall have the right to
                 defend at the expense of the Indemnifying Party the claim with
                 counsel of its choosing reasonably satisfactory to the
                 Indemnifying Party, subject to the right of the Indemnifying
                 Party to assume the defense of any claim at any time prior to
                 settlement or final determination thereof.  Any such defense
                 shall be prosecuted promptly and vigorously by the Indemnified
                 Party.  In the case of either (A) or (B), if the Indemnifying
                 Party has not yet admitted its liability for a claim, the
                 Indemnified Party shall send a written notice to the
                 Indemnifying Party of any proposed settlement of any claim
                 received by the Indemnified Party.  The Indemnifying Party
                 shall have an option for 30 days





                                       28
<PAGE>   29
                 following receipt of such notice to (i) admit liability for
                 the claim if it has not already done so and (ii) if liability
                 has been admitted, reject, in its reasonable judgment, the
                 proposed settlement.  Failure to reject such settlement within
                 such 30-day period shall be deemed an acceptance of such
                 settlement.  If the Indemnified Party settles any such claim
                 over the objection of the Indemnifying Party, the Indemnified
                 Party shall thereby waive any right to indemnity therefor,
                 unless the Indemnifying Party has not prior to the time of
                 settlement admitted liability for such claim.

                          (ii)    In the event any Indemnified Party should
                 have a claim for Losses against any Indemnifying Party
                 hereunder that does not involve a Loss being asserted against
                 or sought to be collected from it by a third party (for
                 example, but without limitation, a Loss resulting from a
                 breach of a representation, warranty or covenant), the
                 Indemnified Party shall send a Claim Notice with respect to
                 such claim to the Indemnifying Party.  If the Indemnifying
                 Party does not notify the Indemnified Party within 30 days
                 from the date the claim notice is given that it disputes such
                 claim for Losses, the amount of such Losses shall be
                 conclusively deemed a liability of the Indemnifying Party
                 hereunder.

         7.3     Sellers' Access to the Company.  If the Closing occurs, then,
following such Closing and upon at least 48 hours' prior written notice, the
Sellers and their employees, representatives and agents shall be given access
during reasonable business hours to the facilities, properties, personnel,
books and non-privileged records of the Company for the purpose of satisfying
any obligations imposed upon the Sellers pursuant to this Agreement, including
without limitation the indemnification obligations imposed pursuant to Section
7.2; provided, however, that such investigation shall be conducted in a manner
that does not interfere with normal operations of the Company.  The Company
will cause the employees, counsel, accountants and other representatives of the
Company to be available to the Sellers and their agents at all reasonable times
during business hours for such purposes.

         7.4     Agreement Not to Compete.

                 (a)      As a further inducement to the Purchaser to enter
         into this Agreement, each Seller agrees that during the period from
         the Closing Date until the fifth anniversary after the latest date
         that any Seller ceases to be an employee of the Purchaser or any of
         its subsidiaries:

                          (i)     No Seller shall, directly or indirectly, for
                 their own account or for the account of others, as an officer,
                 director, passive stockholder, owner, partner, member,
                 promoter, consultant, advisor, employee, manager or otherwise,
                 participate in the promotion, financing, ownership, operation
                 or management of, or assist in, furnish advice with respect
                 to, or carry on through a proprietorship, partnership, joint
                 venture, limited liability company, corporation, other form of
                 business entity or otherwise, any business activity in a
                 geographic market within the State of Texas or any other state
                 where the Company is doing such business or has plans to do
                 such business, involving or relating to the business of
                 distributing, packaging, and processing tortillas, tortilla
                 chips and related products; provided, however, that nothing in
                 this clause (i) shall prohibit any Seller's aggregate
                 beneficial ownership





                                       29
<PAGE>   30
                 of not in excess of 1% of any class of common stock that is
                 listed for trading on a national securities exchange; and

                          (ii)    No Seller shall furnish advice to, solicit,
                 or do business with any customer (or any previous customer
                 within the last year) of the Company or any of its
                 subsidiaries relating to the business of the Company in any
                 geographic market within the State of Texas or any other state
                 where such customer is doing business with the Company or any
                 of its subsidiaries.

                          (iii)   No Seller shall encourage or induce any
                 current or former employee of the Company or any of its
                 subsidiaries or affiliates to leave the employment of the
                 Company or any of its subsidiaries or affiliates, offer
                 employment, retain, hire or assist in the hiring of any such
                 employee by any person, association, or entity not affiliated
                 with the Company or any of its subsidiaries or affiliates.

                 (b)      Although the parties to this Agreement have, in good
         faith, used all reasonable efforts to make this covenant reasonable in
         both geographic area and in duration, and it is not anticipated, nor
         is it intended, by either of the parties to this Agreement that any
         court of competent jurisdiction would find it necessary to reform this
         covenant not to compete to make it reasonable in both geographic area
         and in duration, or otherwise, the parties to this Agreement agree
         that any court of competent jurisdiction making a determination that
         it is necessary to reform this covenant not to compete to make it
         reasonable in either geographic area or duration, or otherwise, shall
         be, and hereby is, empowered and directed to reform this Agreement to
         a reasonable restriction rather than invalidating this covenant or
         otherwise rendering it unenforceable.

                 (c)      In the event of breach by any Seller of this covenant
         not to compete, it is understood and agreed (i) that the Purchaser or
         the Company shall be entitled to injunctive relief as well as any and
         all other applicable remedies at law and in equity; and (ii) that
         damages, if any, for the breach of this covenant not to compete will
         accrue and be recoverable by the Purchaser or any subsidiary as of and
         from the date of the breach insofar as the damages for such breach
         relate to an action that occurred within the scope of the geographic
         area and duration of the covenant not to compete determined to be
         reasonable (whether or not the covenant is reformed in connection with
         such determination).

                                  ARTICLE VIII

                                 MISCELLANEOUS

         8.4     Headings.  The descriptive headings of the several Articles
and Sections of this Agreement are inserted for convenience only and do not
constitute a part of the Agreement.

         8.5     Entire Agreement.  This Agreement, the documents to be
executed hereunder, and the exhibits attached hereto constitute the entire,
completely integrated agreement between the parties hereto pertaining to the
subject matter hereof and supersede all prior agreements, understandings,
negotiations and discussions, whether oral or written, of the parties
pertaining to the subject matter hereof, including without limitation that
certain letter of intent dated October 8, 1997 by and among the Purchaser, the
Company and Saragosa Bazan, Jr., as extended and amended by that certain letter
agreement dated December 15, 1997.

         8.6     Waiver.  At any time prior to the Closing, any party hereto
may (a) extend the time for the performance of any of the obligations or other
acts of any other party hereto or (b) waive compliance with any of the
agreements of any other party or with any conditions to its own obligations.
Any agreement on the part of a party hereto to any such extension or waiver
shall be valid if set forth in an instrument in writing signed on behalf of
such party. The consummation of the transactions contemplated hereby shall not
be deemed a waiver of the right any party may have hereunder with respect to
any other party's representations, warranties, covenants or agreements
contained in or related to this Agreement being incorrect, untrue or breached.

         8.7     Amendment.  This Agreement may not be amended except by an
instrument in writing signed by each of the parties hereto.  No supplement,
alteration or modification of this Agreement shall be binding unless executed
in writing by the parties hereto.

         8.8     Public Statements.  After the date here of and prior to the
Closing Date, Sellers, the Company and the Purchaser shall consult with each
other with regard to all publicity, general employee announcements and public
announcements concerning this Agreement and the transactions contemplated
hereby and, except as required by applicable law or the applicable rules or
regulations of any governmental body or stock exchange (including, without
limitation, the Nasdaq Stock Market), no party shall issue a press release or
announcement concerning this Agreement and the transactions contemplated hereby
without the prior written consent of the other parties hereto, which shall not
be unreasonably withheld.  On or after the Closing Date, Sellers shall not
issue a press release or announcement concerning this Agreement and the
transactions contemplated hereby without the prior written consent of the
Purchaser.





                                       32
<PAGE>   33
         8.9     Further Actions. Each party shall execute and deliver such
other certificates, agreements and other documents and take such other actions
as may reasonably be requested by the other parties in order to consummate or
implement the transactions contemplated by this Agreement.  Without limiting
the foregoing, Sellers agree to perform any reasonable acts necessary to obtain
state, federal or foreign registration of any Mark currently used in the
Company's business as now conducted.  Without limiting the foregoing, if, at
any time or from time to time after the Closing, the Purchaser, the Company or
any Seller shall identify any Related Asset that was not transferred to the
Company as required by Section 4.9, then the Sellers shall immediately
transfer, without additional consideration, all of their rights, ownership and
interest in any such Related Asset to the Company, free and clear of any
mortgage, pledge, lien, charge, encumbrance or other adverse claim.  Such
transfer shall be effected pursuant to conveyance documents in form and
substance satisfactory to the Purchaser in its reasonable judgment.

         8.10    Assignment.  No Seller may assign or delegate any of its
rights or duties hereunder, without the prior written consent of the Purchaser.
Any assignment or delegation made without such consent shall be void.  Except
as otherwise provided herein, this Agreement shall be binding upon and inure to
the benefit of the parties hereto and their respective permitted successors,
assigns and legal representatives.

         8.11    Independent Covenants.  The covenants contained herein are
independent and separate, and in the event that any provision contained herein
is declared invalid or illegal, the other provisions hereof shall not be
affected or impaired thereby and shall remain valid and enforceable.

         8.12    Specific Performance.  In the event of a breach or threatened
breach by any party hereto of the provisions of this Agreement, any other party
hereto shall be entitled to specific performance.  Nothing herein shall be
construed as prohibiting any party hereto from pursuing any other remedies
available for such breach or threatened breach, including the recovery of
damages.

         8.13    Governing Law.  This Agreement and the other documents
delivered pursuant hereto and the legal relations between the parties shall be
governed and construed in accordance with the laws of the State of Texas,
without giving effect to principles of conflict of laws.

         8.14    Counterparts.  This Agreement may be executed in any number of
counterparts, each of which when so executed shall be deemed an original but
all of which together shall constitute one and the same instrument.

         8.15    Withholding or Granting of Consent.  Except as otherwise
provided in this Agreement, each party hereto may, with respect to any consent
or approval that it is entitled to grant pursuant to this Agreement or any
other document or instrument or agreement delivered or entered into pursuant
hereto, grant or withhold such consent or approval in its sole and uncontrolled
discretion, with or without cause, and subject to such conditions as it shall
deem appropriate.

         8.16    No Third Party Beneficiaries.  Nothing in this Agreement shall
provide any benefit to any third party or entitle any third party to any claim,
cause of action, remedy or right of any kind, it being the intent of the
parties that this Agreement shall not be construed as a third party beneficiary
contract; provided, however, that the indemnification provisions in Sections
7.2 shall inure to the benefit of the Purchaser Indemnitees and the Seller
Indemnitees as provided therein.
