            ADDITIONAL PURCHASE PRICE

            (a) Buyer will cause the Company's CPAs, within forty-five (45) days

        the Company for the one month period of January 1, 2002 through January
        31, 2002 ("Review"). Upon completion of the Review, Buyer will forward a
        copy of the Review to Seller. The Review will include a list of the

        hundred twenty (120) days of the date of invoice for Mexican accounts
        receivable as of December 31, 2001.

            (b) Seller covenants and agrees that as of December 31, 2001 the

        due and payable within twelve (12) months, accrued liabilities and
        lessee's deposits incurred in the Ordinary Course of Business. All
        customer deposits and escrow liabilities shall be treated as a long term
        liability and all cash collateral required to fund such liabilities
        shall be treated as a long term asset.

            (c) Seller covenants and agrees that as of December 31, 2001 the
        Company will have at least $3,150,000.00 in Net Working Capital of which
        at least $400,000.00 shall be in cash ("Net Working Capital
        Requirement"). If the Net Working Capital, as indicated by the Review,
        exceeds $3,150,000.00 as of December 31, 2001, such excess amount over
        $3,150,000.00 shall be paid to Seller by Buyer in the form of additional
        Purchase Price in cash within ten (10) days following the receipt of the
        Review by Buyer. If the additional Purchase Price payment described

        Seller, the unpaid amount shall bear interest at the rate of seven and
        one-half percent (7.5%) per annum until paid. If the Review indicates
        that the Net Working Capital Requirement is not met, then Seller will
        pay in cash to Buyer the amount necessary to equal the Net Working
        Capital Requirement in ten (10) days following notice thereof. In
        addition, the amount of any accounts receivable of the Company accrued
        prior to December 31, 2001 and not included in determining the Net
        Working Capital Requirement shall be paid to Seller when collected by
        Buyer as additional purchase price.

            (d) If as of April 30, 2002 all or any portion of the accounts
        receivable that were included in the Net Working Capital Requirement as
        indicated in the Review, are not collected by Buyer, then Buyer will
        transfer and assign such uncollected accounts receivable or portion
        thereof, as applicable, to Seller in return for cash equal to the full
        value of such unpaid accounts receivable. Seller will pay to Buyer in
        cash within five (5) days after written notice, the amount of such
        accounts receivable or portion thereof not collected as of April 30,
        2002 that was included in the Net Working Capital Requirement. Buyer
        will cooperate and assist Seller in collecting such accounts receivable
        so transferred. Any accounts receivable of the Company collected by
        Buyer after April 30, 2002, that were fully reserved or not included in
        the Net Working Capital Requirement and, shall be paid to Seller by
        Buyer as additional Purchase Price upon collection of such accounts
        receivable.

            (e) The Company's CPA's will determine the Company's net income or
        loss, as the case may be, in accordance with GAAP for the period
        beginning January 1, 2002 through January 31, 2002. Upon receipt of the
        Review indicating such net income or loss, either (i) the Company will
        pay to Seller in the event of net income, such amount of net income for
        the month of January, 2002 as additional Purchase Price within ten (10)
        days following receipt of the Review or (ii) in the event of net loss
        the Buyer shall first offset such amount of net loss against any
        additional Purchase Price due Seller under subsection (b) above, or
        Seller shall pay in cash to Buyer the amount of the net loss within 10
        days following receipt of the Review.

        other jurisdictions in which it is authorized to do business, and its

        qualified to do business as a foreign corporation and is in good
        standing under the laws of each state or other jurisdiction in which
        either the ownership or use of the properties owned or used by it, or

        qualification.

            Seller have delivered to Buyer copies of the Organizational
        Documents of the Company, as currently in effect.

        accordance with GAAP, subject, in the case of interim financial
        statements to normal recurring year-end adjustments (the effect of which
        will not, individually or in the aggregate, be materially adverse) and

        Balance Sheet (except for assets held under capitalized leases disclosed
        or not required to be disclosed in Part 3.6 of the Disclosure Letter and

        Business), and all of the properties and assets purchased or otherwise
        acquired by the Company since the date of the Balance Sheet (except for

        and assets, (a) mortgages or security interests shown on the Balance
        Sheet or the Interim Balance Sheet as securing specified liabilities or
        obligations, with respect to which no default (or event that, with
        notice or lapse of time or both, would constitute a default) exists, (b)
        mortgages or security interests incurred in connection with the purchase
        of property or assets after the date of the Interim Balance Sheet (such
        mortgages and security interests being limited to the property or assets
        so acquired), with respect to which no default (or event that, with
        notice or lapse of time or both, would constitute a default) exists, (c)
        liens for current taxes not yet due, and (d) with respect to real
        property, (i) minor imperfections of title, if any, none of which is

        Company, and (ii) zoning laws and other land use restrictions that do
        not impair the present or anticipated use of the property subject
        thereto. All buildings, plants, and structures owned by the Company lies
        wholly within the boundaries of the real property owned by the Company
        and does not encroach upon the property of, or otherwise conflict with
        the property rights of, any other Person.

            (b) The Company has no long term secured indebtedness as of the
        Closing Date and no assets, real or personal property, are subject to

for the uses to which they are being put, and none of such buildings, plants,
structures, or equipment is in need of maintenance or repairs except for
ordinary, routine maintenance and repairs that are not material in nature or
cost. The building, plants, structures, and equipment of the Company are
sufficient for the continued conduct of the Company's businesses after the
Closing in substantially the same manner as conducted prior to the Closing.

        3.8    ACCOUNTS RECEIVABLE

        All accounts receivable of the Company that are reflected on the Interim
Balance Sheet or on the accounting records of the Company as of the Closing Date
(collectively, the "Accounts Receivable") represent or will represent valid
obligations arising from sales actually made or services actually performed in
the Ordinary Course of Business. Unless paid prior to the Closing Date, the
Accounts Receivable are or will be as of the Closing Date current and
collectible net of the respective reserves shown on the Interim Balance Sheet or
on the accounting records of the Company as of the Closing Date (which reserves
are adequate and calculated consistent with past practice and, in the case of
the reserve as of the Closing Date, will not represent a greater percentage of
the Accounts Receivable as of the Closing Date than the reserve reflected in the
Interim Balance Sheet represented of the Accounts Receivable reflected therein
and will not represent a material adverse change in the composition of such
Accounts Receivable in terms of aging). Subject to such reserves, each of the
Accounts Receivable either has been or will be collected in full, without any
set-off, within 90-days of the date of invoice (except in the case of foreign
accounts receivable, within 120-days of the date of invoice). There is no
contest, claim, or right of set-off, other than returns in the Ordinary Course
of Business, under any Contract with any obligor of an Accounts Receivable
relating to the amount or validity of such Accounts Receivable. Part 3.8 of the
Disclosure Letter contains a complete and accurate list of all Accounts
Receivable as of the date of the Agreement, which list sets forth the aging of
such Accounts Receivable.

Balance Sheet, consists of a quality and quantity usable and salable in the
Ordinary Course of Business, except for obsolete items and items of
below-standard quality, all of which have been written off or written down to
net realizable value in the Interim Balance Sheet or on the accounting records
of the Company as of the Closing Date, as the case may be. The quantities of
each item of inventory (whether raw materials, work-in-process, or finished
goods) are not excessive, but are reasonable in the present circumstances of the
Company.

        Except as set forth in Part 3.10 of the Disclosure Letter, the Company

        filed since January 1, 1996. The Company has paid, or made provision for
        the payment of, all Taxes that have or may have become due pursuant to
        those Tax Returns or otherwise, or pursuant to any assessment received
        by Seller or the Company, except such Taxes, if any, as are listed in
        Part 3.11 of the Disclosure Letter and are being contested in good faith
        and as to which adequate reserves (determined in accordance with GAAP)
        have been provided in the Balance Sheet and the Interim Balance Sheet.

             (b) Part 3.11 of the Disclosure Letter contains a complete and
        accurate list of all audits of all such Tax Returns, including a
        reasonably detailed description of the nature and outcome of each audit.
        All deficiencies proposed as a result of such audits have been paid,
        reserved against, settled, or, as described in Part 3.11 of the
        Disclosure Letter, are being contested in good faith by appropriate
        proceedings. Part 3.11 of the Disclosure Letter describes all
        adjustments to the United States federal income Tax Returns filed by the
        Company or any group of corporations including the Company for all
        taxable years since January 1, 1996, and the resulting deficiencies
        proposed by the IRS. Except as described in Part 3.11 of the Disclosure
        Letter, neither Seller or the Company has given or been requested to
        give waivers or extensions (or is or would be subject to a waiver or
        extension given by any other Person) of any statute of limitations
        relating to the payment of Taxes of the Company or for which the Company
        may be liable.

             (c) The charges, accruals, and reserves with respect to Taxes on
        the respective books of the Company are adequate (determined in
        accordance with GAAP) and are at least equal to the Company's liability
        for Taxes. There exists no proposed tax assessment against the Company
        except as disclosed in the Interim Balance Sheet or in Part 3.11 of the
        Disclosure Letter. No consent to the application of Section 341(f)(2) of
        the IRC has been filed with respect to any property or assets held,
        acquired, or to be acquired by the Company. All Taxes that the Company
        is or was required by Legal Requirements to withhold or collect have
        been duly withheld or collected and, to the extent required, have been
        paid to the proper Governmental Body or other Person.

             (d) All Tax Returns filed by (or that include on a consolidated
        basis) the Company are true, correct, and complete. There is no tax
        sharing agreement that will require any payment by the Company after the
        date of this Agreement. The Company is not, nor within the five-year
        period preceding the Closing Date has been, an "S" corporation. During
        the consistency period (as defined in Section 338(h)(4) of the IRC with
        respect to the sale of the Shares to Buyer), neither the Company or any
        target affiliate (as defined in Section 338(h)(6) of the IRC with
        respect to the sale of the Shares to Buyer) has sold or will sell any
        property or assets to Buyer or to any member of the affiliated group (as
        defined in Section 338(h)(5) of the IRC) that includes Buyer. Part 3.11
        of the Disclosure Letter lists all such target affiliates.

        prior to the Closing Date, or (B) any Hazardous Activities that were, or
        were allegedly, conducted by Seller or the Company or by any other
        Person for whose conduct they are or may be held responsible; or

            any bodily injury (including illness, disability, and death, and
        regardless of when any such bodily injury occurred, was incurred, or
        manifested itself), personal injury, property damage (including
        trespass, nuisance, wrongful eviction, and deprivation of the use of
        real property), or other damage of or to any Person, including any
        employee or former employee of Seller or the Company or any other Person
        for whose conduct they are or may be held responsible, in any way
        arising from or allegedly arising from any Hazardous Activity conducted
        or allegedly conducted with respect to the Facilities or the operation
        of the Company prior to the Closing Date, or from Hazardous Material
        that was (i) present or suspected to be present on or before the Closing
        Date on or at the Facilities (or present or suspected to be present on
        any other property, if such Hazardous Material emanated or allegedly
        emanated from any of the Facilities and was present or suspected to be
        present on any of the Facilities on or prior to the Closing Date) or
        (ii) Released or allegedly Released by Seller or the Company or any
        other Person for whose conduct they are or may be held responsible, at
        any time on or prior to the Closing Date.

            Buyer will be entitled to control any Cleanup, any related
        Proceeding, and, except as provided in the following sentence, any other
        Proceeding with respect to which indemnity may be sought under this
        Section 8.3. The procedure described in Section 8.9 will apply to any
        claim solely for monetary damages relating to a matter covered by this
        Section 8.3. Upon consummation of this Agreement, Buyer agrees to
        maintain or provide for comprehensive general liability insurance
        coverage for the Company which will be at least as good or better than
        the coverage provided by the Company's insurance, and provide that no
        lapse of insurance coverage for liability matters will be allowed to
        transpire as a result of this Agreement. It is expressly provided herein
        that in the event the Seller discloses an environmental condition or
        liability through the Disclosure Letter, the Indemnified Persons will
        not be entitled to indemnification under this Agreement for the
        liability relating to such disclosure. It is also expressly provided
        herein that in the event the Seller specifically discloses an
        environmental condition as liability through the Closing, the
        Indemnified Persons will not be entitled to indemnification under this
        Agreement for the environmental condition or liability relating to such
        disclosure except for claims by Third Parties.

        8.4 INDEMNIFICATION AND PAYMENT OF DAMAGES BY BUYER

        Buyer will indemnify and hold harmless Seller, and will pay to Seller
the amount of any Damages arising, directly or indirectly, from or in connection
with (a) any Breach of any representation or warranty made by Buyer in this
Agreement or in any certificate delivered by Buyer pursuant to this Agreement,
(b) any Breach by Buyer of any covenant or obligation of Buyer in this
Agreement, or (c) any claim by any Person for brokerage or finder's fees or

                                       56
<PAGE>

commissions or similar payments based upon any agreement or understanding
alleged to have been made by such Person with Buyer (or any Person acting on its
behalf) in connection with any of the Contemplated Transactions.

        8.5 TIME LIMITATIONS

        If the Closing occurs, Seller will have no liability (for
indemnification or otherwise) with respect to any representation or warranty, or
covenant or obligation to be performed and complied with prior to the Closing
Date, other than those in Sections 3.3, 3.11, 3.13, and 3.19, unless on or
before two (2) years from the Closing Date Buyer notifies Seller of a claim
specifying the factual basis of that claim in reasonable detail to the extent
then known by Buyer; a claim with respect to Section 3.3, 3.11, 3.13, or 3.19,
or a claim for indemnification or reimbursement not based upon any
representation or warranty or any covenant or obligation to be performed and
complied with prior to the Closing Date, may be made at any time. If the Closing
occurs, Buyer will have no liability (for indemnification or otherwise) with
respect to any representation or warranty, or covenant or obligation to be
performed and complied with prior to the Closing Date, unless on or before two
(2) years from the Closing Date Seller notifies Buyer of a claim specifying the
factual basis of that claim in reasonable detail to the extent then known by
Seller. Notwithstanding any of the foregoing in this Section 8.5, the
indemnification pursuant to Section 8.2(d) hereof is not subject to any time
limitation hereunder.

        8.6 LIMITATIONS ON AMOUNT--SELLER

            (a) Seller will have no liability (for indemnification or otherwise)
        with respect to the matters described in clause (a), clause (b) or, to
        the extent relating to any failure to perform or comply prior to the
        Closing Date, clause (c) of Section 8.2 until the total of all Damages
        with respect to such matters exceeds $25,000.00, and then only for the
        amount by which such Damages exceed $25,000.00. In no event shall the
        aggregate indemnification to be provided by Seller pursuant to the
        matters described in Section 8.2(a), (b), (c) and (e) exceed
        $2,000,000.00. In the event Buyer makes a claim for indemnification
        pursuant to clauses (a), (b), (c) or (e) of Section 8.2 and is entitled
        to indemnification pursuant to the terms of this Article VIII, Buyer and
        Seller agree that any such indemnification will be first set off against
        amounts due under the Note, including principal and accrued interest,
        and if such indemnification exceeds the amounts due under the Note, the
        excess shall be paid in cash.

            Seller agrees to pay all Damages and defend at Seller's cost the
        matters described in clause (d) of Section 8.2 hereof, and to pay to
        Buyer in cash any Damages for which Buyer may be entitled pursuant to
        Section 8.2(d).

            However, this Section 8.6 will not apply to any Breach of any of
        Seller's representations and warranties of which Seller had Knowledge at
        any time prior to the date on which such representation and warranty is
        made or any intentional Breach by Seller of any covenant or obligation.

        8.7 LIMITATIONS ON AMOUNT--BUYER

                                       57
<PAGE>

        Buyer will have no liability (for indemnification or otherwise) with
respect to the matters described in clause (a) or (b) of Section 8.4 until the
total of all Damages with respect to such matters exceeds $25,000.00, and then
only for the amount by which such Damages exceed $25,000.00. In no event shall
the aggregate indemnification to be provided by Buyer pursuant to this Article
VIII exceed $5,000,000.00. However, this Section 8.7 will not apply to any
Breach of any of Buyer's representations and warranties of which Buyer had
Knowledge at any time prior to the date on which such representation and
warranty is made or any intentional Breach by Buyer of any covenant or
obligation, and Buyer will be liable for all Damages with respect to such
Breaches.

        8.8 PROCEDURE FOR INDEMNIFICATION--THIRD PARTY CLAIMS

            Promptly after receipt by an indemnified party under Section 8.2,
        8.4, or (to the extent provided in the last sentence of Section 8.3)
        Section 8.3 of notice of the commencement of any Proceeding against it,
        such indemnified party will, if a claim is to be made against an
        indemnifying party under such Section, give notice to the indemnifying
        party of the commencement of such claim, but the failure to notify the
        indemnifying party will not relieve the indemnifying party of any
        liability that it may have to any indemnified party, except to the
        extent that the indemnifying party demonstrates that the defense of such
        action is prejudiced by the indemnifying party's failure to give such
        notice.

            If any Proceeding referred to in Section 8.8(a) is brought against
        an indemnified party and it gives notice to the indemnifying party of
        the commencement of such Proceeding, the indemnifying party will, unless
        the claim involves Taxes, be entitled to participate in such Proceeding
        and, to the extent that it wishes (unless (i) the indemnifying party is
        also a party to such Proceeding and the indemnified party determines in
        good faith that joint representation would be inappropriate, or (ii) the
        indemnifying party fails to provide reasonable assurance to the
        indemnified party of its financial capacity to defend such Proceeding
        and provide indemnification with respect to such Proceeding), to assume
        the defense of such Proceeding with counsel satisfactory to the
        indemnified party and, after notice from the indemnifying party to the
        indemnified party of its election to assume the defense of such
        Proceeding, the indemnifying party will not, as long as it diligently
        conducts such defense, be liable to the indemnified party under this
        Section 8 for any fees of other counsel or any other expenses with
        respect to the defense of such Proceeding, in each case subsequently
        incurred by the indemnified party in connection with the defense of such
        Proceeding, other than reasonable costs of investigation. If the
        indemnifying party assumes the defense of a Proceeding, (i) it will be
        conclusively established for purposes of this Agreement that the claims
        made in that Proceeding are within the scope of and subject to
        indemnification; (ii) no compromise or settlement of such claims may be
        effected by the indemnifying party without the indemnified party's
        consent unless (A) there is no finding or admission of any violation of
        Legal Requirements or any violation of the rights of any Person and no
        effect on any other claims that may be made against the indemnified
        party, and (B) the sole relief provided is monetary damages that are
        paid in full by the indemnifying party; and (iii) the indemnified party
        will have no liability with respect to any compromise or settlement of
        such claims effected without its consent. If notice is given to an
        indemnifying party of the commencement of any Proceeding and the
        indemnifying party does not, within ten days after the indemnified
        party's notice is given, give notice to the indemnified party of its
        election to assume the defense of such Proceeding, the indemnifying
        party will be bound by any determination made in such Proceeding or any
        compromise or settlement effected by the indemnified party.

            Notwithstanding the foregoing, if an indemnified party determines in
        good faith that there is a reasonable probability that a Proceeding may
        adversely affect it or its affiliates other than as a result of monetary
        damages for which it would be entitled to indemnification under this
        Agreement, the indemnified party may, by notice to the indemnifying
        party, assume the exclusive right to defend, compromise, or settle such

                                       58
<PAGE>

        Proceeding, but the indemnifying party will not be bound by any
        determination of a Proceeding so defended or any compromise or
        settlement effected without its consent (which may not be unreasonably
        withheld).

        8.9 PROCEDURE FOR INDEMNIFICATION--OTHER CLAIMS

        A claim for indemnification for any matter not involving a third-party
claim may be asserted by notice to the party from whom indemnification is
sought.

        8.10 RIGHT OF SET-OFF

        Buyer will give written notice to Seller for a claim for indemnification
and set-off specifying the details and the basis for such right to
indemnification and set-off which it may be entitled under this Section 8
against amounts otherwise payable under the Promissory Note. Within ten (10)
days after receipt of notice by Seller, Seller must respond in writing to Buyer,
and either : (a) agree that Buyer's claim for indemnification and right to
set-off is valid, in which case Buyer will set-off such amount, or (b) dispute
such set-off, in which case the parties will arbitrate such dispute in
accordance with this Agreement and no set-off will occur unless and until a
final order authorizing such set-off is entered by the Arbitrator. If Seller
fails to respond in writing within ten (10) days to Buyer's written notice,
Seller shall be deemed to have agreed with Buyer's claim for indemnification and
Buyer may set-off against the Promissory Note. Neither the exercise of, nor the
failure to, exercise such right of set-off will constitute an election of
remedies or limit Buyer in any manner in the enforcement of any other remedies
that may be available to it.

        9.  GENERAL PROVISIONS

        9.1 EXPENSES

        Except as otherwise expressly provided in this Agreement, each party to
this Agreement will bear its respective expenses incurred in connection with the
preparation, execution, and performance of this Agreement and the Contemplated
Transactions, including all fees and expenses of agents, representatives,
counsel, and accountants. Seller will pay all amounts payable to Dillard
Anderson Group in connection with this Agreement and the Contemplated
Transactions. In the event of termination of this Agreement, the obligation of
each party to pay its own expenses will be subject to any rights of such party
arising from a breach of this Agreement by another party. In addition, in the
event of dispute involving this Agreement, the party who defaulted under the
Agreement will pay the attorney's fees, expenses, court costs and expert's fees
of the non-defaulting party.

        9.2 PUBLIC ANNOUNCEMENTS

        Any public announcement or similar publicity with respect to this
Agreement or the Contemplated Transactions will be issued, if at all, at such
time and in such manner as Buyer determines. Unless consented to by Buyer in
advance or required by Legal Requirements, prior to the Closing Seller shall,
and shall cause the Company to, keep this Agreement strictly confidential and
may not make any disclosure of this Agreement to any Person. Seller and Buyer
will consult with each other concerning the means by which the Company's
employees, customers, and suppliers and others having dealings with the Company
will be informed of the Contemplated Transactions, and Buyer will have the right
to be present for any such communication.

        9.3 CONFIDENTIALITY

        Between the date of this Agreement and the Closing Date, Buyer and

employees, agents, and advisors of Buyer and the Company to maintain in
confidence, written information stamped "confidential" when originally furnished
by another party or the Company in connection with this Agreement or the
Contemplated Transactions, unless (a) such information is already known to such
party or to others not bound by a duty of confidentiality or such information
becomes publicly available through no fault of such party, (b) the use of such
information is necessary or appropriate in making any filing or obtaining any
consent or approval required for the consummation of the Contemplated
Transactions, or (c) the furnishing or use of such information is required by or
necessary or appropriate in connection with legal proceedings.

        If the Contemplated Transactions are not consummated, each party will

        9.5 BINDING ARBITRATION

                                       60
<PAGE>

            On the request of any party hereto, whether made before or after the
        institution of any legal proceeding, any action, dispute, claim or
        controversy of any kind now existing or hereafter arising between any of
        the parties hereto in any way arising out of, pertaining to or in
        connection with this Agreement (a "Dispute") shall be resolved by
        binding arbitration in accordance with the terms hereof. In the event of
        any Dispute, any party may serve written notice of such Dispute on any
        other party and each party to such Dispute shall undertake in good faith
        to resolve such Dispute. If the parties cannot agree to resolve such
        Dispute within fifteen (15) days after such written notice, any party to
        such Dispute may, by further written notice (the "Arbitration Notice")
        to the other party, commence an arbitration proceeding by bringing the
        Dispute to one arbitrator or to an arbitration panel selected as
        provided below.

            Arbitrators. Dispute shall be decided by a single arbitrator, unless
        the parties cannot agree within ten (10) days on a single arbitrator, in
        which case they shall choose an arbitration panel comprised of three
        arbitrators, one arbitrator to be selected by the party who sent the
        Arbitration Notice, a second arbitrator to be selected by the other
        adverse party, and the third arbitrator (the "Independent Arbitrator")
        who will be the Chairman of the arbitration panel, to be appointed by
        the first two arbitrators. In the event the first two arbitrators fail
        to agree on the appointment of the Independent Arbitrator within fifteen
        (15) days, the Independent Arbitrator shall be appointed on request of
        any party hereto by any state district court judge in Hidalgo or Harris
        County, Texas. Whether there is one arbitrator or a panel, each
        arbitrator shall be a third party and a business person knowledgeable in
        the subject matter of the Dispute. In the event that any arbitrator
        shall resign, be unable or otherwise fail to perform his or her duties,
        each party shall immediately notify the other parties of such
        resignation, inability or failure, and a replacement shall immediately
        be selected by the party who selected such arbitrator in the instance,
        or, if the arbitrator to be replaced is the Independent Arbitrator, then
        the parties shall attempt in good faith to appoint a mutually agreeable
        replacement Independent Arbitrator. If the parties fail to agree on such
        replacement within fifteen (15) days, either party may request any state
        district court judge in Hidalgo or Harris County, Texas to appoint such
        replacement Independent Arbitrator.

            Conduct of Arbitration. The arbitrator or the arbitration panel
        shall conduct the arbitration in accordance with the Rules of
        Arbitration of the American Arbitration Association then in effect,
        except to the extent such rules are inconsistent with the provisions of
        this Section 13. The parties shall prepare in writing a statement of
        their positions, together with counterclaims, with supporting facts,
        data, and affidavits, if any, and shall submit such statement to the
        arbitrator, or arbitration panel within fifteen (15) days after
        selection, but, in any event, within forty-five (45) days after service
        of the Arbitration Notice. The arbitrator or the arbitration panel shall
        give all parties the opportunity to make an oral presentation to the
        arbitrator or the arbitration panel in the presence of the other party,
        if either party so requests. The parties shall have, for a period of
        one-hundred twenty (120) days after service of the Arbitration Notice
        (the "Discovery Period"), all rights of discovery provided by the Texas
        Rules of Civil Procedures then obtaining, except, unless otherwise
        agreed, that all responses to discovery requests shall be served within
        ten (10) days of such discovery request and no discovery request may be
        served after the date ten (10) days before the termination of the
        Discovery Period. The arbitrator or the arbitration panel shall assume
        exclusive jurisdiction over the Dispute, may order interim equitable
        relief (which shall be specifically enforceable as if it were a final
        Award, as hereinafter defined), and shall be required to make a final
        binding determination (the "Award"). The Award shall not be subject to
        appeal to or review by any court or administrative body except as set
        forth in Section 10(a) of the Federal Arbitration Act,

                                       61
<PAGE>

        codified as 9 U.S.C.A. Section 10(a) (West Supp. 1997). The Award shall
        determine (i) whether each party's obligations under this Agreement were
        met, and (ii) what damages or remedies (which may include final
        equitable reliefs) are due under the terms of this Agreement. In
        addition, the arbitrator or the arbitration panel shall award recovery
        of all costs and fees of arbitration to the prevailing party. The
        agreement to arbitrate contained in this Section 13 shall be
        specifically enforceable under the prevailing arbitration law, and shall
        survive termination of this Agreement. Judgment upon the Award rendered
        by the arbitrator or the arbitration panel may be entered in accordance
        with applicable law in any court having jurisdiction therefor.
        Arbitration shall, unless all the parties otherwise agree in writing,
        take place in Houston, Texas.

        9.6 FURTHER ASSURANCES

        The parties agree (a) to furnish upon request to each other such further
information, (b) to execute and deliver to each other such other documents, and
(c) to do such other acts and things, all as the other party may reasonably
request for the purpose of carrying out the intent of this Agreement and the
documents referred to in this Agreement. Buyer agrees to provide Seller with
copies of quarterly financial statements and audited year end financial
statements until the Note is paid in full.

        9.7 WAIVER

        The rights and remedies of the parties to this Agreement are cumulative
and not alternative. Neither the failure nor any delay by any party in
exercising any right, power, or privilege under this Agreement or the documents
referred to in this Agreement will operate as a waiver of such right, power, or
privilege, and no single or partial exercise of any such right, power, or
privilege will preclude any other or further exercise of such right, power, or
privilege or the exercise of any other right, power, or privilege. To the
maximum extent permitted by applicable law, (a) no claim or right arising out of
this Agreement or the documents referred to in this Agreement can be discharged
by one party, in whole or in part, by a waiver or renunciation of the claim or
right unless in writing signed by the other party; (b) no waiver that may be
given by a party will be applicable except in the specific instance for which it
is given; and (c) no notice to or demand on one party will be deemed to be a
waiver of any obligation of such party or of the right of the party giving such
notice or demand to take further action without notice or demand as provided in
this Agreement or the documents referred to in this Agreement.

        9.8 ENTIRE AGREEMENT AND MODIFICATION

        This Agreement supersedes all prior agreements between the parties with
respect to its subject matter (including the Letter of Intent between Buyer and
Seller dated May 2, 2001) and constitutes (along with the documents referred to
in this Agreement) a complete and exclusive statement of the terms of the
agreement between the parties with respect to its subject matter. This Agreement
may not be amended except by a written agreement executed by the party to be
charged with the amendment.

        9.9 DISCLOSURE LETTER

            (a) The disclosures in the Disclosure Letter, must relate only to
        the representations and warranties in the Section of the Agreement to

Breach of any representation or warranty made by Seller in this Agreement, the
schedules hereto or any other certificate or document delivered by Seller
pursuant to this Agreement; (b) any Breach by Seller or the Company of any
covenant or obligation of Seller or the Company in this Agreement; or (c) any
claim by any Person for brokerage or finder's fees or commissions or similar
payments based upon any agreement made by any such Person with Seller or the
Company (or any Person acting on their behalf) in connection with any of the
transactions contemplated herein.

        The remedies provided in this Section 0 will be the sole remedy
available to Buyer and the Other Indemnified Persons.

                Indemnification and Payment of Damages by Buyer. Buyer will
indemnify and hold harmless Seller and its Representatives, stockholders,
controlling persons, and affiliates, and will pay to such Persons the amount of
any Damages arising from (a) any Breach of any representation or warranty made
by Buyer in this Agreement or in any Schedule or certificate delivered by Buyer
pursuant to this Agreement, (b) any Breach by Buyer of any covenant or
obligation of Buyer in this Agreement, or (c) any valid claim by any Person for
brokerage or finder's fees or commissions or similar payments based upon any
agreement made by such Person with Buyer (or any Person acting on its behalf) in
connection with any of the transactions contemplated herein.

                Procedure for Indemnification -- Third Party Claims.

Promptly after receipt by an indemnified party under Section 5.2 or Section 5.3
of notice of the commencement of any Proceeding against it, such indemnified
party will, if a claim is to be made against an indemnifying party under such
Section, give notice to the indemnifying party of the commencement of such
claim, but the failure to notify the indemnifying party will not relieve the
indemnifying party of any liability that it may have to any indemnified party,
except to the extent that the indemnifying party

                                    Page 72
<PAGE>

demonstrates that the defense of such action is prejudiced by the indemnifying
party's failure to give such notice.

If any Proceeding referred to in Section 00 is brought against an indemnified
party and it gives notice to the indemnifying party of the commencement of such
Proceeding, the indemnifying party will, unless the claim involves taxes, be
entitled to participate in such Proceeding and, to the extent that it wishes
(unless (i) the indemnifying party is also a party to such Proceeding and the
indemnified party determines in good faith that joint representation would be
inappropriate, or (ii) the indemnifying party fails to provide reasonable
assurance to the indemnified party of its financial capacity to defend such
Proceeding and provide indemnification with respect to such Proceeding), to
assume the defense of such Proceeding with counsel satisfactory to the
indemnified party and, after notice from the indemnifying party to the
indemnified party of its election to assume the defense of such Proceeding, the
indemnifying party will not, as long as it diligently conducts such defense, be
liable to the indemnified party under this Section 0 for any fees of other
counsel or any other expenses with respect to the defense of such Proceeding, in
each case subsequently incurred by the indemnified party in connection with the
defense of such Proceeding, other than reasonable costs of investigation. If the
indemnifying party assumes the defense of a Proceeding; (i) it will be
conclusively established for purposes of this Agreement that the claims made in
that Proceeding are within the scope of and subject to indemnification; (ii) no
compromise or settlement of such claims may be effected by the indemnifying
party without the indemnified party's consent unless (1) there is no finding or
admission of any violation of Legal Requirements or any violation of the rights
of any Person and no effect on any other claims that may be made against the
indemnified party, and (2) the sole relief provided is monetary damages that are
paid in full by the indemnifying party; and (3) the indemnified party will have
no liability with respect to any compromise or settlement of such claims
effected without its consent. If notice is given to an indemnifying party of the
commencement of any Proceeding and the indemnifying party does not, within ten
days after the indemnified party's notice is given, give notice to the
indemnified party of its election to assume the defense of such Proceeding, the
indemnifying party will be bound by any determination made in such Proceeding or
any compromise or settlement effected by the indemnified party.

Notwithstanding the foregoing, if an indemnified party determines in good faith
that there is a reasonable probability that a Proceeding may adversely affect it
or its affiliates other than as a result of monetary damages for which it would
be entitled to indemnification under this Agreement, the indemnified party may,
by notice to the indemnifying party, assume the exclusive right to defend,
compromise, or settle such Proceeding, but the indemnifying party will not be
bound by any determination of a Proceeding so defended or any compromise or
settlement effected without its consent (which may not be unreasonably
withheld).

Seller hereby consents to the non-exclusive jurisdiction of any court in which a
Proceeding is brought against any Indemnified Person for purposes of any claim
that an Indemnified Person may have under this Agreement with respect to such
Proceeding on the matters alleged therein, and agree that process may be served
on Seller with respect to such claim anywhere in the world.

                Procedure for Indemnification -- Other Claims. A claim for
indemnification for any matter not involving a third-party claim may be asserted
by notice to the party from whom indemnification is sought.

                Limitations on Amounts for Damages. Seller shall be entitled to
satisfy and pay the entirety of any Damages to Buyer with respect to any matters
described in Section 0, by the delivery to Buyer of that number of Buyer Shares
having a value equal to the amount of such Damages. For the purposes of this
Section 0, the Buyer Shares will be valued at the average closing price of Buyer
Common Stock during the ten trading days immediately preceding the Closing, as
such term is defined in Section 2.5. The total aggregate liability of Seller to
Buyer for Damages under this Agreement shall be limited, under all
circumstances, to the aggregate value of the Buyer Shares delivered to Seller
pursuant to Section 2.2(a), as such value is calculated in accordance with this
Section 0. The total aggregate liability of Buyer to Seller shall be limited to
the aggregate value of the Buyer Shares delivered to Seller pursuant to Section
2.2(a), as such value is calculated in accordance with this Section 0.

are cumulative and not alternative. Neither the failure nor any delay by any
party in exercising any right, power, or privilege under this Agreement or the

given by a party will be applicable except in the specific instance for which it
is given; and (c) no notice to or demand on one party will be deemed to be a

notice or demand to take further action without notice or demand as provided in
this Agreement or the documents referred to in this Agreement.

                Entire Agreement and Modification. This Agreement supersedes all
prior agreements between the parties with respect to its subject matter

with the amendment.

                Assignments, Successors, and No Third-Party Rights. Neither
party may assign any of its rights under this Agreement without the prior
consent of the other parties. Subject to the preceding sentence, this Agreement
will apply to, be binding in all respects upon, and inure to the benefit of the
successors and permitted assigns of the parties. Nothing expressed or referred
to in this Agreement will be construed to give any Person other than the parties
to this Agreement any legal or equitable right, remedy, or claim under or with
respect to this Agreement or any provision of this Agreement. This Agreement and
all of its provisions and conditions are for the sole and exclusive benefit of
the parties to this Agreement and their successors and assigns.
