         4.8 Inventories. To the Best Knowledge of Seller, the inventories of
Target reflected on the Reference Balance Sheet consist of items of a quality
and quantity usable and saleable in the normal course of business of Target at
an aggregate value at least equal to the value at which such inventories are
reflected on the Reference Balance Sheet. The method of valuing such
inventories as of the Balance Sheet Date is consistent with that used in
respect of the beginning and end of each of the two (2) most recent fiscal
years of Target. The value of obsolete materials and materials below standard
quality has been written down on the books of account of Target to realizable
market value, or adequate reserves have been provided therefor. The inventories
of Target are not excessive in kind or amount in light of the business done or
reasonably expected to be done by it. The values at which such inventories are
carried reflect the inventory valuation policy applied by Target of stating
inventory at the lower of actual cost or average actual cost in accordance with
generally accepted accounting principles.
         4.9 Taxes and Governmental Returns. To the Best Knowledge of Seller,
of the date hereof, all Tax returns, information returns and governmental
reports of every nature required by any Governmental Authority or Governmental
Requirement to be filed by Target or which include or should include Target,
including, but not limited to, those relating to Taxes of any nature to which
Target or any of its business is subject ("Governmental Returns"), have been
filed for all periods ending on or before the date hereof, and all Taxes shown
to be due and payable on such Governmental Returns or on any assessments
related to such Governmental Returns have been paid. All such Governmental
Returns and reports and the information and data contained therein have been
properly and accurately compiled and completed, fairly present the information
purported to be shown therein, and reflect all Tax liabilities of Target for

                                      -10-

   13



the periods covered by such Governmental Returns. Except as specifically
disclosed in this Agreement or the Schedules hereto, Target has no unpaid
liability for any Taxes of any nature whatsoever for any period prior to the
date hereof. The Governmental Returns of Target or that include Target have not
been audited, and are not now under audit, by any Governmental Authority. There
are no agreements, waivers or other arrangements providing for an extension of
time with respect to the assessment of any Taxes of any nature against Seller
or with respect to any Governmental Return filed by Seller or that include
Seller, or any suits or other actions, proceedings, investigations or claims
now pending or threatened against Target with respect to any Taxes or any
matters under discussion with any Governmental Authority relating to any Taxes,
or any claims for additional Taxes asserted by any Governmental Authority. The
charges, accruals and reserves on the Reference Balance Sheet in respect of all
accrued Taxes are adequate to provide fully for all Taxes, if any, payable by
Target with respect to periods ended on or before the date of this Agreement.
         4.10 Employee Benefit Plans. Except as set forth on Schedule 4.10,
Target has no employee benefit plans (including, but not limited to, pension
plans and health or welfare plans), arrangements or understandings, whether
formal or informal. Target does not now and has never contributed to a
"multiemployer plan" as defined in section 4001(a)(3) of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA"). Target has
complied with all applicable provisions of ERISA and all rules and regulations
promulgated thereunder and neither Target nor any trustee, administrator,
fiduciary, agent or employee thereof has at any time been involved in a
transaction that would constitute a "prohibited transaction" within the meaning
of Section 406 of ERISA. Target is not a party to any collective bargaining or
other union

                                      -11-

   14



agreements. Target has not, within the last five years, had or been threatened
with any union activities, work stoppages or other labor trouble with respect
to its employees which had or might have had a material adverse effect on the
business of Target. To the Best Knowledge of Seller, no union activities, work
stoppages or other labor trouble with respect to the employees of any of the
customers or suppliers of the business of Target are pending or threatened
which might have an adverse effect on the business of Target. Other than wage
increases in the ordinary course of business, since the Balance Sheet Date
Target has not made any commitment or agreement to increase the wages or modify
the conditions or terms of employment of any of the employees of Target used in
connection with its business.

(collectively, the

                                      -13-

   16



"Contracts") are valid, binding and in full force and effect in accordance with
their terms and conditions and there is no existing default thereunder or
breach thereof by Target or, to the Best Knowledge of Seller, by any other
party to the Contracts, or any conditions which, with the passage of time or
the giving of notice or both, might constitute such a default by Target, or, to
the Best Knowledge of Seller, by any other party to the Contracts, and the
Contracts will not be breached by or give any other party a right of
termination as a result of the transactions contemplated by this Agreement. To
the Best Knowledge of Seller there is no reason why any of the Contracts (i)

readily be fulfilled or performed by Target on time without undue or unusual
expenditure of money or effort. Copies of all of the documents (or in the case

and the consummation of the transactions contemplated hereby will not (i)

default under, the Articles of Incorporation or other charter documents or
bylaws of Target or Seller, or any commitment, mortgage, note, bond, debenture,
deed of trust, contract, agreement, license or other instrument or obligation
to which Target or Seller is now a party or by which Target or Seller or any of
its properties or assets may be bound or affected; (ii) result in any violation
of any Governmental Requirement; (iii) cause Target to lose the benefit of any
right or privilege it presently enjoys or, to the Best Knowledge of

                                      -14-

   17



Seller, cause any Person who normally does business with Target not to continue
to do so on the same basis as before; (iv) relieve any Person of any obligation
to Target (whether contractual or otherwise) or enable any Person to terminate
any such obligation or any right or benefit enjoyed by Target or to exercise
any right under any agreement in respect of Target or the assets or business of

order of any Person. To the Best Knowledge of Seller, the business

adversely affected by the execution and delivery of this Agreement or the
consummation of the transactions contemplated hereby.

leasehold estates, real and personal, set forth in Schedule 4.13, free and
clear of all mortgages, liens, pledges, conditional sales agreements, charges,
easements, covenants, assessments, restrictions and encumbrances of any nature
whatsoever. All leases of property under which Target purports to be a lessee

equipment and other properties owned or used by Target are in good operating
condition and repair, normal wear and tear excepted, and are capable of being
used for their intended purpose in the business of Target as now conducted. All
such

                                      -15-

   18



plants, structures, equipment and other properties of Target and the present
use of such items conform to all Governmental Requirements, and no notice of
any violation of any such Governmental Requirements relating to such assets or
their use has been received by Target. Target has all easements, rights of
ingress and egress, and utilities and services necessary for all operations
conducted by it. Neither the whole nor any portion of any real property owned
or occupied by Target has been condemned or otherwise taken by any public
authority, nor, to the Best Knowledge of Seller, is any such condemnation or
taking threatened or planned.
         4.14 Intangible Property. Except as set forth on Schedule 4.14, Target
does not own, and its business does not require the use of, any rights under
any patents, inventions, trademarks, trade names, brand names or copyrights,
and the operation of its business as presently conducted does not violate or
infringe upon any such items owned by any Person. Neither Seller nor any
officer, director, employee, consultant or agent of Target has entered into any
agreement regarding know-how, trade secrets, assignment of rights in
inventions, or prohibition or restriction of competition or solicitation of
customers, or any other similar restrictive agreement or covenant, whether

legality of the transactions contemplated hereby, (ii) no basis or grounds for

insurance policies (specifying the insurer, the amount of coverage, the type of
insurance and the policy number) maintained by Target on its properties,
assets, business and personnel. Such policies afford Target coverage in such
amounts and against such risks as is customary for companies engaged in the
same type and scope of business as Target. There are no special circumstances
with respect to such policies or the business or operations of Target that lead
to any liability under such insurance policies being avoided by the insurers
issuing such policies or, to the Best Knowledge of Seller, the premiums
thereunder being increased. Except as set forth on Schedule 4.16, there is no
claim outstanding under any such insurance policy nor, to the Best Knowledge of
Seller, any circumstances that are likely to give rise to such a claim. Target
is not in default with respect to any provision contained in such insurance
policies, nor has it failed to give

                                      -17-

fully paid.

facts giving rise to a claim for indemnity under the provisions of this
Agreement, including receipt by it or any Indemnified Party of notice of any
demand, assertion, claim, action or proceeding, judicial or otherwise, by any
Person with respect to any matter as to which any of the Indemnified Parties

         13.   REQUIREMENTS OF SECURITIES LAWS.
         13.1  Accredited Investors.  Seller recognizes that the Convertible 
Note and the Conversion Shares (collectively, the "Securities") are not being 
registered under the Securities Act in reliance upon an exemption from the 
Securities Act which is

                                      -40-

   43



predicated, in part, on the representations and agreements of Seller set forth
in this Agreement. Seller represents and warrants to Purchaser that Seller is
an "accredited investor" as that term is defined in Rule 501(a) of the
Securities Act and that the Securities are being acquired solely for its own
account for investment and not with a view to, or for offer or resale in
connection with, a distribution thereof within the meaning of the Securities
Act. Seller understands that the effect of such representation and warranty is
that the Securities must be held indefinitely unless subsequently registered
under the Securities Act or an exemption from such registration is available at
the time for any proposed sale or other transfer thereof. Seller also
understands that Purchaser is under no obligation to file a registration
statement under the Securities Act covering the Securities or to take any other
action to enable Seller to transfer or otherwise dispose of the Securities.
Seller represents that it has consulted with counsel in regard to the
Securities Act and that it is fully familiar with the circumstances under which
it is required to hold the Securities and the limitations upon the transfer or
other disposition thereof. Seller acknowledges that Purchaser is relying upon
the truth and accuracy of the foregoing representations and warranties in
issuing the Securities under the Securities Act. Seller agrees to indemnify and
hold Purchaser harmless against all liabilities, costs and expenses, including
reasonable attorneys' fees, incurred by Purchaser as a result of any sale,
transfer or other disposition by Seller of all or any part of the Securities in
violation of the Securities Act.
         13.2     Legend.  The Securities shall bear the following legend:
                  "THE SECURITIES REPRESENTED BY THIS CERTIFI-
                  CATE HAVE BEEN ACQUIRED FOR INVESTMENT AND
                  HAVE NOT BEEN REGISTERED UNDER THE SECURI-

                                      -41-

   44



                  TIES ACT OF 1933, AS AMENDED.  THESE SECURITIES
                  MAY NOT BE SOLD OR TRANSFERRED IN THE AB-
                  SENCE OF SUCH REGISTRATION OR AN EXEMPTION
                  THEREFROM UNDER SAID ACT.

         13.3 SEC Documents. Purchaser shall provide to Seller (a) a copy of
the Annual Report on Form 10-K of Purchaser for the fiscal year ended August
31, 1995, in the form filed with the SEC, and (b) copies of all filings since
August 31, 1995 by Purchaser with the SEC in compliance with Section 13 or 14
of the Exchange Act. At closing Seller will represent that it has reviewed the
foregoing documents and acknowledges it has been afforded the opportunity to
obtain any additional information necessary to verify the accuracy of the
information contained in the foregoing documents, including the opportunity to
ask questions of, and receive answers from, officers and representatives of
Purchaser concerning Purchaser and the terms and conditions of the transactions
contemplated by this Agreement. Seller acknowledges that David Hooper, attorney
at law, has advised Seller during the course of the negotiation of this
Agreement, and that Seller has consulted David Hooper, attorney at law, with
respect to the transactions contemplated by this Agreement.
         13.4 Incidental Registration. If, at any time after the Closing Date,
Purchaser proposes to register any of the Purchaser's Common Stock (whether
unissued, yet to be authorized or held by any person) under the Securities Act,
it shall, at least 30 days prior to the filing under the Securities Act of the
registration statement relating thereto, give written notice to Seller of its
intention to do so, and, upon the written request of Seller given within 10
days after the giving of any such notice (which request

                                      -42-

   45



shall state the proposed method of distribution), Purchaser shall include or
cause to be included in any such registration statement the Conversion Shares;
provided, however, that Purchaser may at any time withdraw or cease proceeding
with any such registration if it shall at the time withdraw or cease proceeding
with the registration of such Purchaser's Common Stock originally proposed to
be registered; and provided further, that if the registration proposed by
Purchaser relates to an underwritten offering, Seller shall not have any right
to sell the Conversion Shares in any manner or through any underwriter other
than in the manner and through the managing underwriter or underwriters being
used by Purchaser.
                  a. Notwithstanding any other provision of this Section 13.4,
if a registration pursuant to this Section 13.4 involves a firm commitment,
underwritten offering of the securities so being registered and if the managing
underwriter of such offering informs Purchaser and Seller by letter of its
belief that marketing factors require a limitation of the number of shares to
be underwritten, Purchaser may limit the amount of Conversion Shares to be
included in the registration and underwriting; provided that no such reduction
shall reduce the securities being offered by Purchaser for its own account; and
provided that those shares which are excluded from the underwritten offering
shall be withheld from the market by the holders thereof for a period, not to
exceed 180 days, which the managing underwriter reasonably determines as
necessary in order to effect the underwritten offering.
                  b.  Registration Procedures and Expenses.  If and whenever
Purchaser is required to include the Conversion Shares in a registration 
statement under the Securities Act, as provided in Section 13.4 hereof, 
Purchaser shall, as expeditiously as is reasonably practicable, do each of the 
following:

                                      -43-

   46



                           (i) prepare and file with the SEC a registration
         statement with respect to the Conversion Shares and, subject to the
         limitations under Section 13.4 hereof, use its best efforts to cause
         such registration statement to become effective;
                           (ii) cooperate with Seller and any underwriter who
         shall sell the Conversion Shares in connection with their review of
         Purchaser made in connection with such registration;
                           (iii) prepare and file with the SEC such amendments
         and supplements to such registration statement and the prospectus used
         in connection therewith as may be necessary to keep such registration
         statement effective for 120 days from the date of its effectiveness,
         and to comply with the provisions of the Securities Act and the
         Exchange Act with respect to the disposition of all the Conversion
         Shares covered by such registration statement for such period;
                           (iv) furnish to Seller such number of copies of the
         prospectus forming a part of such registration statement (including
         each preliminary prospectus), in conformity with the requirements of
         the Securities Act, and such other documents as Seller may reasonably
         request in order to facilitate the disposition of the Conversion
         Shares; and
                           (v) Purchaser shall (x) notify Seller at any time
         when a prospectus relating to the Conversion Shares is required to be
         delivered under the Securities Act, of the happening of any event as a
         result of which the prospectus forming a part of such registration
         statement, as then in effect, includes an untrue statement of a
         material fact or omits to state any material fact required to be

                                      -44-

   47



         stated therein or necessary to make the statements therein not
         misleading in the light of the circumstances then existing, and (y) at
         the request of Seller, prepare and furnish to Seller a reasonable
         number of copies of any supplement to or any amendment of such
         prospectus that may be necessary so that, as thereafter delivered to
         the purchasers of the Conversion Shares such prospectus shall not
         include any untrue statement of a material fact or omit to state a
         material fact required to be stated therein or necessary to make the
         statements therein not misleading in the light of the circumstances
         then existing.
                  c.  Agreement by Seller.  In the event that Seller 
participates, pursuant to this Section 13.4, in the offering of the Conversion 
Shares Seller shall;
                           (i) furnish Purchaser all material information
         reasonably requested by Purchaser concerning Seller and the proposed
         method of sale or other disposition of the Conversion Shares and such
         other information and undertakings as shall be reasonably required in
         connection with the preparation and filing of the registration
         statement covering the Conversion Shares in order to ensure full
         compliance with the Securities Act and the rules and regulations of
         the SEC thereunder;
                           (ii) cooperate in good faith with Purchaser and its
         underwriters, if any, in connection with such registration, including
         placing the Conversion Shares in escrow or custody to facilitate the
         sale and distribution thereof provided that such escrow or custody
         arrangement shall be no more restrictive upon Seller than upon any
         other holder of Purchaser Stock for the benefit of whom such
         registration is undertaken; and

                                      -45-

   48



         (iii) make no further sales or other dispositions, or offers therefor,
     of the Conversion Shares under such registration statement if, during the
     effectiveness of such registration statement, an intervening event should
     occur which, in the opinion of counsel to Purchaser, makes the prospectus
     included in such registration statement no longer comply with the
     Securities Act, so long as written notice containing the facts and legal
     conclusions relied upon by Purchaser in this regard has been received by
     Seller from Purchaser, until such time as Seller has received from
     Purchaser copies of a new, amended or supplemented prospectus complying
     with the Securities Act, which prospectus shall be delivered to Seller by
     Purchaser as soon as practicable after such notice. d. Allocation of
     Expenses. If and whenever Purchaser is required by the provisions of this
     Section 13.4 to use its best efforts to effect the registration of the
     Conversion Shares under the Securities Act, Purchaser shall pay the costs
     and expenses in connection therewith; provided, however, that Seller shall
     pay all underwriting discounts, selling commissions and stock transfer
     taxes attributable to the Conversion Shares under such registration
     statement.
      e. Indemnification. In the event of any registration of any of the
Conversion Shares under the Securities Act pursuant to this Section 13.4,
Seller shall indemnify and hold harmless, Purchaser, each director of
Purchaser, each officer of Purchaser who shall sign such registration
statement, each underwriter and any person who controls Purchaser or such
underwriter within the meaning of the Securities Act, with respect to any
statement in or omission from such registration statement, any preliminary
prospectus or final prospectus contained therein, or any amendment or
supplement thereto, if such statement or omission was made in reliance upon and
in

                                      -46-

   49



conformity with written information furnished to Purchaser or its underwriter
through an instrument duly executed by any of Seller specifically for use in
the preparation of such registration statement, preliminary prospectus, final
prospectus or amendment or supplement.
         14. ACCESS TO BOOKS AND RECORDS. Seller represents and warrants to
Purchaser that all of the existing books and records of Target are physically
located at the principal office of Target in Abilene, Texas. Purchaser
covenants that for a period of six (6) years after the date of this Agreement
it will provide Seller with reasonable access to such books and records of
Target covering periods prior to the Closing Date as are reasonably needed in
connection with (i) the preparation of any Tax returns of Seller or (ii) any
dispute between Seller and any Person.
         15. NON-COMPETITION AGREEMENT. Unless a default by Purchaser under the
terms and conditions of the Convertible Note shall have occurred and be then

nor any Affiliate of Seller shall, within the state of Texas, (i) compete
directly or indirectly with the business engaged in by Target as of the Closing
Date, (ii) solicit directly or indirectly any of the accounts of Target or
(iii) become the employee or consultant of or otherwise render services to, or
own any interest in, any enterprise that directly or indirectly competes with
the business engaged in by Target as of the Closing Date. For purposes of this
Section 15, the term "accounts" shall mean any Person for which Target has
performed or does perform services or to which Target has sold or does sell
merchandise during the period beginning two (2) years immediately prior to the
date of this Agreement and ending one (1) year after the date of this
Agreement.

                                      -47-

   50



         Seller agrees that the limitations set forth herein on the rights of
it and its Affiliates to compete with Target are reasonable and necessary for
the protection of Target. In this regard, Seller specifically agrees that the
limitations as to period of time and geographic area, as well as all other
restrictions specified herein, are reasonable and necessary for the protection
of Target. Seller further recognizes and agrees that violation of any of the
agreements contained in this Section 15 will cause irreparable damage or injury
to Target and Purchaser, the exact amount of which may be impossible to
ascertain, and that, for such reason, among others, Target and Purchaser shall
be entitled to an injunction, without the necessity of posting bond therefor,
restraining any further violation of such agreements. Such rights to any
injunction shall be in addition to, and not in limitation of, any other rights
and remedies Target or Purchaser may have against the undersigned, including,
but not limited to, the recovery of damages. Further, it is agreed by Seller
that in the event that the provisions of this Section 15 should ever be deemed
to exceed the time or geographic limitations permitted by applicable law, then
such provisions shall be reformed to the maximum time or geographic limitations
permitted.
         16. NONDISCLOSURE OF CONFIDENTIAL INFORMATION. Seller and Purchaser
recognize and acknowledge that they have and will have access to certain
confidential information of Target, such as lists of customers, and costs and
financial information, that is valuable, special and unique property of Target.
Seller and Purchaser agree that they will not disclose, and they will use their
best efforts to prevent disclosure by any other Person of, any such
confidential information to any Person or for any purpose or reason whatsoever,
except to authorized representatives of Purchaser or Seller as the case may be.
Seller and Purchaser recognize and agree

                                      -48-

   51



that violation of any of the agreements contained in this Section 16 will cause
irreparable damage or injury to Target, Seller and Purchaser, the exact amount
of which may be impossible to ascertain, and that, for such reason, among
others, Target, Seller and Purchaser shall be entitled to an injunction,
without the necessity of posting bond therefor, restraining any further
violation of such agreements. Such rights to any injunction shall be in
addition to, and not in limitation of, any other rights and remedies Target,
Seller or Purchaser may have against the undersigned.
         17. DAMAGE TO ASSETS. If, on or before the Closing Date, the assets or
properties of Target are damaged or destroyed in excess of $50,000.00, Seller
will immediately notify Purchaser of such damage or destruction. In the event
of any such damage or destruction, Purchaser and Seller shall have the right,
in the sole discretion of Seller or Purchaser, to either (i) reduce the
Purchase Price by an amount equal to the value of the damaged or destroyed
asset or assets, and complete the purchase, or (ii) terminate this Agreement as
provided by Section 23.3 hereof and not complete the purchase.
         18. EXPENSES.  Whether or not the transactions contemplated hereby are
consummated, each of the parties will pay all costs and expenses of its 
performance of and compliance with this Agreement.

   52



settled by arbitration in Houston, Texas pursuant to the rules of the State of
Texas. If Purchaser on the one hand and Seller, on the other hand cannot
jointly select a single arbitrator to determine the matter, one arbitrator
shall be chosen by Purchaser on the one hand and Seller, on the other hand (or,
if either fails to make a choice, by a court of competent jurisdiction on
behalf of such party) and the two arbitrators so chosen will select a third.
The decisions of the single arbitrator jointly selected by the parties, or, if
three arbitrators are selected, the decision of any two of them, will be final
and binding upon the parties and the judgment of a court of competent
jurisdiction may be entered thereon. Each party shall pay the fees and expenses
of its chosen arbitrator, and the fees and expenses of the third arbitrator
shall be shared equally by the parties.

provided that any party may change its address for notice by giving to the

by telex or telegram or by facsimile or other similar instantaneous electronic
transmission device, 24 hours after sending and (iii) if mailed, 48 hours after
mailing.
         22.      GENERAL PROVISIONS.
         22.1 Governing Law; Interpretation; Section Headings. This Agreement
shall be governed by and construed and enforced in accordance with the laws of
the State of Texas. The section headings contained herein are for purposes of
convenience only, and shall not be deemed to constitute a part of this
Agreement or to affect the meaning or interpretation of this Agreement in any
way.
         22.2 Severability. Should any provision of this Agreement be held
unenforceable or invalid under the laws of the United States of America or the
State of Texas, or under any other applicable laws of any other jurisdiction,
then the parties hereto

                                      -51-

   54



agree that such provision shall be deemed modified for purposes of performance
of this Agreement in such jurisdiction to the extent necessary to render it
lawful and enforceable, or if such a modification is not possible without
materially altering the intentions of the parties hereto, then such provision
shall be severed herefrom for purposes of performance of this Agreement in such
jurisdiction. The validity of the remaining provisions of this Agreement shall
not be affected by any such modification or severance, except that if any
severance materially alters the intentions of the parties hereto as expressed
herein (a modification being permitted only if there is no material
alteration), then the parties hereto shall use commercially reasonable effort
to agree to appropriate equitable amendments to this Agreement in light of such
severance, and if no such agreement can be reached within a reasonable time,
any party hereto may initiate arbitration as provided in Section 20 above.
         22.3 Entire Agreement. This Agreement sets forth the entire agreement
and understanding of the parties hereto with respect to the transactions
contemplated hereby, and supersedes all prior agreements, arrangements and
understandings related to the subject matter hereof. No representation,
promise, inducement or statement of intention has been made by any party hereto
which is not embodied in this Agreement, and no party hereto shall be bound by
or liable for any alleged representation, promise, inducement or statement of
intention not so set forth.
         22.4 Binding Effect.  All the terms, provisions, covenants and 
conditions of this Agreement shall be binding upon and inure to the benefit of
and be enforceable by the parties hereto and their respective successors and 
assigns.

                                      -52-

   55



         22.5 Assignment. Except as specifically permitted herein, this
Agreement and the rights and obligations of the parties hereto shall not be
assigned or delegated by either party hereto without the prior written consent
of the other party hereto.
         22.6 Amendment; Waiver. This Agreement may be amended, modified,
superseded or canceled, and any of the terms, provisions, representations,
warranties, covenants or conditions hereof may be waived, only by a written
instrument executed by all parties hereto, or, in the case of a waiver, by the
party waiving compliance. The failure of any party at any time or times to
require performance of any provision hereof shall in no manner affect the right
to enforce the same. No waiver by any party of any condition contained in this
Agreement, or of the breach of any term, provision, representation, warranty or
covenant contained in this Agreement, in any one or more instances, shall be
deemed to be or construed as a further or continuing waiver of any such
condition or breach, or as a waiver of any other condition or of the breach of
any other term, provision, representation, warranty or covenant.
         22.7 Counterparts. This Agreement may be executed simultaneously in
two or more counterparts, each of which shall be deemed an original, but all of
which together shall constitute one and the same instrument. This Agreement
shall be binding when one or more counterparts hereof, individually or taken
together, shall bear the signatures of the parties reflected hereon as
signatories.
         22.8 Telecopy Execution and Delivery. A facsimile, telecopy or other
reproduction of this Agreement may be executed by one or more parties hereto,
and an executed copy of this Agreement may be delivered by one or more parties
hereto by facsimile or similar instantaneous electronic transmission device
pursuant to which the signature of or on behalf of such party can be seen, and
such execution and delivery

                                      -53-

   56



shall be considered valid, binding and effective for all purposes. At the
request of either party hereto, all parties hereto agree to execute an original
of this Agreement as well as any facsimile, telecopy or other reproduction
hereof.
         22.9 Guaranty. It is agreed and understood by both Seller and
Purchaser that no shareholder, director, officer or employee of either Seller
or Purchaser shall be called upon to guarantee the performance of Seller,
Purchaser or Target under this Agreement. The only guaranties and/or
commitments binding upon any of such parties shall be those specifically set
forth in this Agreement, and no other shall be implied by either Seller or
Purchaser.
         22.10 Joint Venture Agreement with Superior Fishing and Rental, Inc.
Target has heretofore entered into a Joint Venture Agreement dated January 8,
1996, with Superior Fishing and Rental, Inc., a Texas corporation (herein
"Superior"). A true and correct copy of such agreement has been tendered to
Purchaser's legal counsel. Such agreement covers the terms and conditions of a
joint venture entered into between such parties regarding assets formerly owned
by Small Fishing and Rental, Inc. (herein the "Small Assets") and requires
joint venture distributions to be made by Target to Superior as more
specifically set forth in Section 1.5 of said agreement. Seller's shareholder,
Lacy J. Harber, has given a personal guaranty to Superior that the obligations
of Target under such agreement would be timely met, including the said joint
venture distributions. Any delay by Target of more than three business days in
making payment to Superior of any joint venture distribution will require that
Lacy J. Harber personally make payment to Superior of the delinquent joint
venture distribution, or at the option of Superior, the said Joint Venture
Agreement may be terminated and the Small Assets delivered to Superior. It is
understood and agreed

                                      -54-

   57



that after the Closing Date, Purchaser shall cause Target to timely make to
Superior each and every joint venture distribution required under the Joint
Venture Agreement. Purchaser agrees that Purchaser's failure to cause Target to
make any of such joint venture distributions to Superior will subject Purchaser
to the claims of Lacy J. Harber for any damages suffered by him under his
guaranty to Superior of the obligations of Target under the said Joint Venture
Agreement dated January 8, 1996. Venue for any litigation filed by Lacy J.
Harber against Purchaser for Target's failure to make any joint venture
distribution or distributions to Superior shall be in Taylor County, Texas.
         22.11 The Small Assets. At time of entering into the Joint Venture
Agreement with Superior, Target was required to take the Small Assets on a
"where is" and "as is" basis without any representations regarding the
suitability or condition of the Small Assets. Seller does not, by this
Agreement enlarge the obligations of Target or Seller regarding the said Small
Assets. Purchaser must take the Small Assets on the same "where is" and "as is"
basis and condition that Target acquired same in the Joint Venture Agreement
with Superior.
         23.      TERMINATION.  This Agreement may be terminated without further
obligation of the parties, as follows:
         23.1     Mutual Consent.  This Agreement may be terminated at any time
prior to Closing by mutual written consent of the parties hereto.
         23.2 Failure of Conditions. By either party hereto, if the conditions,
as set forth in this Agreement, to such party's obligations under this
Agreement are not fulfilled on or prior to the Closing Date; provided that any
such termination shall not limit the remedies otherwise available to such party
as a result of misrepresentations of or breaches by the other party.

                                      -55-

   58



         23.3 Damage to Assets. Without limiting Purchaser's rights under this
Agreement, the Agreement may be terminated by Purchaser at its sole option, if
on or prior to the Closing Date, any of the assets or properties of Target are
destroyed or damaged having a fair market value in excess of $50,000.00.
         23.4 Failure to Close. This Agreement will automatically terminate on
July 31, 1996, if the Closing shall not have occurred on or before such date,
unless the parties shall have otherwise agreed in writing prior to such date;
provided, however, that in the event the auditors of Purchaser cannot
reasonably complete the audit of Target by July 31, 1996, such termination date
shall be extended to August 31, 1996 (the "Termination Date"). There will be no
further extensions of said Termination Date. No party will be liable in damages
to any other party as a result of termination pursuant to this Section 23.4
unless the failure of the Closing was due to the failure of such party to
comply with the terms of this Agreement.
