OBLIGATIONS OF GRANTOR.  Grantor warrants and covenants to Lender as follows:

         ORGANIZATION.  Grantor is a corporation which is duly organized,
         validly existing, and in good standing under the laws of the state of
         Grantor's incorporation.

         AUTHORIZATION.  The execution, delivery, and performance of this
         Agreement by Grantor have been duly authorized by all necessary action
         by organization, or bylaws, or any agreement or other instrument
         binding upon Grantor or (b) any law, governmental regulation, court
         decree, or order applicable to Grantor.

         PERFECTION OF SECURITY INTEREST.  Grantor agrees to execute such
         financing statements and to take whatever other actions are requested
         by Lender to perfect and continue Lender's security interest in the
         Collateral.  Upon request of Lender, Grantor will deliver to Lender
         any and all of the documents evidencing or constituting the
         Collateral, and Grantor will note Lender's interest upon any and all
         chattel paper if not delivered to Lender for possession by Lender.
         Grantor hereby appoints Lender as the irrevocable attorney in fact for
         the purpose of executing any documents necessary to perfect or to
         continue the security interest granted in this Agreement.  Lender may
         at any time and without further authorization from Grantor, file a
         carbon, photographic or other reproduction of any financing statement
         or of this Agreement for use as a financing statement.  Grantor will
         reimburse Lender for all expenses for the perfection and the
         continuation of the perfection of Lender's security interest in the
         Collateral.  Grantor promptly will notify Lender before any change in
         Grantor's name including any change in the assumed business names of
         Grantor.  THIS IS A





                                       3
   4

         CONTINUING SECURITY AGREEMENT AND WILL CONTINUE IN EFFECT EVEN THOUGH
         ALL OR ANY PARTY OF THE INDEBTEDNESS IS PAID IN FULL AND EVEN THOUGH
         FOR A PERIOD OF TIME GRANTOR MAY NOT BE INDEBTED TO LENDER.

         NO VIOLATION.  The execution and delivery of this Agreement will not
         violate any law or agreement governing Grantor or to which Grantor is
         a party, and its certificate or articles of incorporation and bylaws
         do not prohibit any term or condition of this Agreement.

         ENFORCEABILITY OF COLLATERAL.  To the extent the Collateral consists
         of accounts, chattel paper, or general intangibles, the Collateral is
         enforceable in accordance with its terms, is genuine, and complies
         with applicable laws concerning form, content and manner of
         preparation and execution, and all persons appearing to be obligated
         on the Collateral have authority and capacity to contract and are in
         fact obligated as they appear to be on the Collateral.

         LOCATION OF THE COLLATERAL.  Grantor, upon request of Lender, will
         deliver to Lender in form satisfactory to Lender a schedule of real
         properties and Collateral locations relating to Grantor's operations,
         including without limitation the following: (a) all real property
         owned or being purchased by Grantor; (b) all real property being
         rented or leased by Grantor; (c) all storage facilities owned, rented,
         leased, or being used by Grantor; and (d) all other properties where
         Collateral is or may be located.  Except in the ordinary course of its
         business, Grantor shall not remove the Collateral from its existing
         locations without the prior written consent of Lender.

         REMOVAL OF COLLATERAL.  Grantor shall keep the Collateral (or to the
         extent the Collateral consists of intangible property such as
         accounts, the records concerning the Collateral) at Grantor's address
         shown above, or at such other locations as are acceptable to Lender.
         Except in the ordinary course of its business, including the sales of
         inventory, Grantor shall not remove the Collateral from its existing
         locations without the prior written consent of Lender.  To the extent
         that the Collateral consists of vehicles, or other titled property,
         Grantor shall not take or permit any action which would require
         application for certificates of title for the vehicles outside the
         State of Texas, without the prior written consent of Lender.

         TRANSACTIONS INVOLVING COLLATERAL.  Except for inventory sold or
         accounts collected in the ordinary course of Grantor's business,
         Grantor shall not sell, offer, to sell, or otherwise transfer or
         dispose of the Collateral.  While Grantor is not in default under this
         Agreement, Grantor may sell inventory, but only in the ordinary course
         of its business and only to buyers who qualify as a buyer in the
         ordinary course of business.  A sale in the ordinary course of
         Grantor's business does not include a transfer in partial or total
         satisfaction of a debt or any bulk sale.  Grantor shall not pledge,
         mortgage, encumber or otherwise permit the Collateral to be subject to
         any lien, security interest, encumbrance, or charge, other than the
         security interest provided for





                                       4
   5

         in this Agreement, without the prior written consent of Lender.  This
         includes security interests even if junior in right to the security
         interests granted under this Agreement.  Unless waived by Lender, all
         proceeds from any disposition of the Collateral (for whatever reason)
         shall be held in trust for Lender and shall not be commingled with any
         other funds; provided however, this requirement shall not constitute
         consent by Lender to any sale or other disposition.  Upon receipt,
         Grantor shall immediately delivery any such proceeds to Lender.

         TITLE.  Grantor represents and warrants to Lender that it holds goods
         and marketable title to the Collateral, free and clear of all liens
         and encumbrances except for the lien of this Agreement.  No financing
         statement covering any of the Collateral is on file in any public
         office other than those which reflect the security interest created by
         this Agreement or to which Lender has specifically consented.  Grantor
         shall defend Lender's rights in Collateral against the claims and
         demands of all other persons.

         COLLATERAL SCHEDULES AND LOCATIONS.  Insofar as the Collateral
         consists of inventory, Grantor's shall deliver to Lender, as often as
         Lender shall require, such lists, descriptions, and designations of
         such Collateral as Lender may require to identify the nature, extent,
         and location of such Collateral.  Such information shall be submitted
         for Grantor and each of its subsidiaries or related companies.

         MAINTENANCE AND INSPECTION OF COLLATERAL.  Grantor shall maintain all
         tangible Collateral in good condition and repair.  Grantor will not
         commit or permit damage to or destruction of the Collateral or any
         part of the Collateral.  Lender and its designated representatives and
         agents shall have the right at all reasonable times to examine,
         inspect, and audit the Collateral wherever located.  Grantor shall
         immediately notify Lender of all cases involving the return,
         rejection, repossession, loss or damage of or to any Collateral; of
         any request for credit or adjustment or of any other dispute arising
         with respect to the Collateral; and generally of all happenings and
         events affecting the Collateral or the value or the amount of the
         Collateral.

         TAXES, ASSESSMENTS AND LIENS.  Grantor will pay when due all taxes,
         assessments and liens upon the Collateral, its use or operation, upon
         this Agreement, upon any promissory note or notes evidencing the
         Indebtedness, or upon any of the other Related Documents.  Grantor may
         withhold any such payment or may elect to contest any lien if Grantor
         is in good faith conducting an appropriate proceeding to contest the
         obligation to pay and so long as Lender's interest in the Collateral
         is not jeopardized in Lender's sole opinion.  If the Collateral is
         subjected to a lien which is not discharged within fifteen (15) days,
         Grantor shall deposit with Lender cash, a sufficient corporate surety
         bond or other security satisfactory to Lender in an amount adequate to
         provide for the discharge of the lien plus any interest, costs,
         attorneys' fees or other charges that could accrue as a result of
         foreclosure or sale of the Collateral.  In any contest Grantor shall
         defend itself and Lender and shall satisfy any





                                       5
   6

         final adverse judgment before enforcement against the Collateral.
         Grantor shall name Lender as an additional obligee under any surety
         bond furnished in the contest proceedings.

         COMPLIANCE WITH GOVERNMENTAL REQUIREMENTS.  Grantor shall comply
         promptly with all laws, ordinances, rules and regulations of all
         governmental authorities, now or hereafter in effect, applicable to
         the ownership, production, disposition or use of the Collateral.
         Grantor may contest in good faith any such law, ordinance or
         regulation and withhold compliance during any proceeding, including
         appropriate appeals, so long as Lender's interest in the Collateral,
         in Lender's opinion, is not jeopardized.

         HAZARDOUS SUBSTANCES.  Grantor represents and warrants that the
         Collateral never has been, and never will be so long as this Agreement
         remains a lien on the Collateral, used for the generation,
         manufacture, storage, transportation, treatment, disposal, release or
         threatened release of any hazardous waste or substance, as those terms
         are defined in the Comprehensive Environmental Response, Compensation,
         and Liability Act of 1980, as amended, 42 U.S.C. Section 9601, et seq.
         ("CERCLA"), the Superfund Amendments and Reauthorization Act of 1986,
         Pub. L. No. 99-499 ("SARA"), the Hazardous Materials Transportation
         Act, 49 U.S.C. Section 1801, et seq., the Recourse Conservation and
         Recovery Act, 42 U.S.C. Section 6901, et seq., or other applicable
         state or Federal laws, rules, regulations adopted pursuant to any of
         the foregoing.  The terms "hazardous waste" and "hazardous substance"
         shall also include, without limitation, petroleum and petroleum
         by-products or any fraction thereof and asbestos.  The representations
         and warranties contained herein are based on Grantor's due diligence
         in investigating the Collateral for hazardous wastes and substances.
         Grantor hereby (a) releases and waives any future claims against
         Lender for indemnity or contribution in the event Grantor becomes
         liable for cleanup or other costs under such laws, and (b) agrees to
         indemnify and hold harmless Lender against any all claims and losses
         resulting from a breach of this provision of this Agreement.  This
         obligation to indemnify shall survive the payment of the indebtedness
         and the satisfaction of this Agreement.

         MAINTENANCE OF CASUALTY INSURANCE.  Grantor shall procure and maintain
         all risks insurance, including without limitation fire, theft and
         liability coverage together with such other insurance as Lender may
         require with respect to the Collateral, in form, amounts, coverages
         and basis reasonably acceptable to Lender.  GRANTOR MAY FURNISH THE
         REQUIRED INSURANCE WHETHER THROUGH EXISTING POLICIES OWNED OR
         CONTROLLED BY GRANTOR OR THROUGH EQUIVALENT INSURANCE FROM ANY
         INSURANCE COMPANY AUTHORIZED TO TRANSACT BUSINESS IN THE STATE OF
         TEXAS.  If Grantor fails to provide any required insurance or fails to
         continue such insurance in force, Lender may, but shall not be
         required to, do so at Grantor's expense, and the cost of the insurance
         will be added to the indebtedness.  If any such insurance is





                                       6
   7

         procured by Lender at a rate or charge not fixed or approved by the
         State Board of Insurance, Grantor will be so notified, and Grantor
         will have the option for five (5) days of furnishing equivalent
         insurance through any insurer authorized to transact business in
         Texas.  Grantor, upon request of Lender, will deliver to Lender from
         time to time the policies or certificates of insurance in form
         satisfactory to Lender, including stipulations that coverage will not
         be canceled or diminished without at least fifteen (15) days' prior
         written notice to Lender and not including any disclaimer of the
         insurer's liability for failure to give such a notice.  Each insurance
         policy also shall include an endorsement providing that coverage in
         favor of Lender will not be impaired in any way by any act, omission
         or default of Grantor or any other person.  In connection with all
         policies covering assets in which Lender holds or is offered a
         security interest, Grantor will provide Lender with such loss payable
         or other endorsements as Lender may require.  If Grantor at any time
         fails to obtain or maintain any insurance as required under this
         Agreement, Lender may (but shall not be obligated to) obtain such
         insurance as Lender deems appropriate, including if it so chooses
         "single interest insurance," which will cover only Lender's interest
         in the Collateral.

         APPLICATION OF INSURANCE PROCEEDS.  Grantor shall promptly notify
         Lender of any loss or damage to the Collateral.  Lender may make proof
         of loss if Grantor fails to do so within fifteen (15) days of the
         casualty.  All proceeds of any insurance on the Collateral, including
         accrued proceeds thereon, shall be held by Lender as part of the
         Collateral.  If Lender consents to repair or replacement of the
         damaged or destroyed Collateral, Lender shall, upon satisfactory proof
         of expenditure, pay or reimburse Grantor from the proceeds for the
         reasonable cost of repair or restoration.  If Lender does not consent
         to repair or replacement of the Collateral, Lender shall retain a
         sufficient amount of proceeds to pay all of the indebtedness, and
         shall pay the balance to Grantor.  Any proceeds which have not been
         disbursed within six (6) months after their receipt and which Grantor
         has not committed to the repair or restoration of the Collateral shall
         be used to prepay the Indebtedness.

         INSURANCE RESERVES.  Lender may require Grantor to maintain with
         Lender reserves for payment of insurance premiums, which reserves
         shall be created by monthly payments from grantor of a sum estimated
         by Lender to be sufficient to produce, at least fifteen (15) days
         before the premium due date, amounts at least equal to the insurance
         premiums to be paid.  If fifteen (15) days before payment is due, the
         reserve funds are insufficient, Grantor shall upon demand pay any
         deficiency to Lender.  The reserve funds shall be held by Lender as a
         general deposit and shall constitute a non-interest-bearing account
         which Lender may satisfy by payment of the insurance premiums required
         to be paid by Grantor as they become due.  Lender does not hold the
         reserve funds in trust for Grantor, and Lender is not the agent of
         Grantor for payment of the insurance premiums required to be paid by
         Grantor.  The responsibility for the payment of premiums shall remain
         Grantor's sole responsibility.

   
         INSURANCE REPORTS.  Grantor, upon request of Lender, shall furnish to
         Lender reports on each existing policy of insurance showing such
         information as Lender may reasonably request including the following: 
         (a) the name of the insurer; (b) the risks insured; (c) the amount of
         the policy; (d) the property insured; (e) the then current value on
         the basis of which insurance has been obtained and the manner of 
         determining that value; and (f) the expiration date of the policy.  
         In addition, Grantor shall upon request by Lender (however not more 
         often than annually) have an independent appraiser satisfactory to 
         Lender determine, as applicable, the cash value or replacement costs 
         of the Collateral.
    



                                       7

GRANTOR'S RIGHT TO POSSESSION.  Until default, Grantor may have possession of
the tangible personal property and beneficial use of all the Collateral and may
use it in any lawful manner not inconsistent with this Agreement or the Related
Documents, provided that Grantor's right to possession and beneficial use shall 
not apply to any Collateral where possession of the Collateral by Lender is
required by law to perfect Lender's security interest in such Collateral.  If
Lender at any time has possession of any Collateral, whether before or after an
Event of Default, Lender shall be deemed to have exercised reasonable care in
the custody and preservation of the Collateral, whether before or after an Event
of Default, Lender shall be deemed to have exercised reasonable care in the
custody and preservation of the Collateral if Lender takes such action for that
purpose as Grantor shall request or as Lender, in Lender's sole discretion,
shall deem appropriate under the circumstances, but failure to honor any request
by Grantor shall not itself be deemed to be a failure to exercise reasonable
care.  Lender shall not be required to take any steps necessary to preserve any
rights in the Collateral against prior parties, nor to protect, preserve or
maintain any security interest given to secure the Indebtedness.

EXPENDITURES BY LENDER.  If not discharged or paid when due, Lender may (but

limitation all taxes, liens, security interests, encumbrances, and other
claims, at any time levied or placed on the Collateral.  Lender also may (but
shall not be obligated to) pay all costs for insuring, maintaining and

         financial condition, or Lender believes the prospect of payment or
         performance of the Indebtedness is impaired.

Agreement, at any time thereafter, Lender shall have all the rights of a
secured party under the Texas Uniform Commercial Code.  In addition and without
limitation, Lender may exercise any one or more of the following rights and

         all or any portion of the Collateral and any all certificates of title
         and other documents relating to the Collateral.  Lender may require
         Grantor to assemble the Collateral and make it available to Lender at
         a place to be designated by Lender.  Lender also shall have full power
         to enter, provided Lender does so without a breach of the peace or a
         trespass, upon the property of Grantor to take possession of and
         remove the Collateral.  If the Collateral contains other goods not
         covered by this Agreement at the time of





                                      9
   10

         provided that Lender makes reasonable efforts to return them to
         Grantor after repossession.

         SELL THE COLLATERAL.  Lender shall have full power to sell, lease,
         transfer, or otherwise deal with the Collateral or proceeds thereof in
         its own name or that of Grantor.  Lender may sell the Collateral at
         public auction or private sale.  Unless the Collateral threatens to
         decline speedily in value or is of a type of customarily sold on a
         recognized market, Lender will give Grantor reasonable notice of the
         time after which any private sale or any other intended disposition of
         the Collateral is to be made.  All expenses relating to the
         disposition of the Collateral, including without limitation the (10)
         days before the time of the sale or disposition.  All expenses
         relating to the disposition of the Collateral, including without
         limitation the expenses of retaking, holding, insuring, preparing for
         sale and selling the Collateral, shall become pare of the indebtedness
         secured by this Agreement and shall be payable on demand, with
         interest at the Note rate from date of expenditure until repaid.

         APPOINT RECEIVER.  To the extent permitted by applicable law, Lender
         shall have the following rights and remedies regarding the appointment
         of a receiver:  (a) Lender may have a receiver appointed as a matter
         of right, (b) the receiver may be an employee of Lender and may serve
         without bond, and (c) all fees of the receiver and his or her attorney
         shall become part of the indebtedness secured by this Agreement and
         shall be payable on demand, with interest at the Note rate from date
         of expenditure until repaid.

         COLLECT REVENUES, APPLY ACCOUNTS.  Lender, either itself or through a
         receiver, may collect the payments, rents, income, and revenues from
         the Collateral.  Lender may at any time in its discretion transfer any
         Collateral into its own name or that of its nominee and receive the
         payments, rents, income, and revenues therefrom and hold the same as
         security for the indebtedness or apply it to payment of the
         Indebtedness in such order of preference as Lender may determine.
         Insofar as the Collateral consists of accounts, general intangibles,
         insurance policies, instruments, chattel paper, chooses in action, or
         similar property, Lender may demand, collect, receipt for, settle,
         compromise, adjust, sue for, foreclose, or realize on the Collateral
         as Lender may determine, whether or not indebtedness or Collateral is
         then due.  For these purposes, Lender may, on behalf of and in the
         name of Grantor, receive, open and dispose of mail addressed to
         Grantor; change any address to which mail and payments are to be sent;
         and endorse notes, checks, drafts, money orders, documents of title,
         instruments and items pertaining to payment, shipment, or storage of
         any Collateral.  To facilitate collection, Lender may notify account
         debtors and obligors on any Collateral to make payments directly to
         Lender.

         OBTAIN DEFICIENCY.  If Lender chooses to sell any or all of the
         Collateral, Lender may obtain a judgment against Grantor for any
         deficiency remaining on the indebtedness due to Lender after
         application of all amounts received from the exercise





                                       10
   11

         of the rights provided in this Agreement.  Grantor shall be liable for
         a deficiency even if the transaction in this subsection is a sale of
         accounts or chattel paper.

         OTHER RIGHTS AND REMEDIES.  Lender shall have all the rights and
         remedies of a secured creditor under the provisions of the Uniform
         Commercial Code, as may be amended from time to time.  In addition,
         Lender shall have and may exercise any or all other rights and
         remedies it may have available at law, in equity, or otherwise.

         CUMULATIVE REMEDIES.  All of Lender's rights and remedies, whether
         evidenced by this Agreement or the Related Documents or by any other
         writing, shall be cumulative and may be exercised singularly or
         concurrently.  Election by Lender to pursue any remedy shall not
         exclude pursuit Grantor's failure to perform, shall not affect
         Lender's right to declare a default and to exercise its remedies.

this Agreement:

         under this Agreement shall be joint and several, and all references to

   12

         and every Grantor.  This means that each of the persons signing below
         is responsible for all obligations in this Agreement.

         NOTICES.  All notices required to be given under this Agreement shall

         first class, postage prepaid, addressed to the party to whom the
         notice is to be given at the address shown above.  Any party may
         change its address for notices under this Agreement by giving formal
         written notice to the other parties, specifying that the purpose of
         the notice is to change the party's address.  To the extent permitted
         by applicable law, if there is more than one Grantor, notice to any
         Grantor will constitute notice to all Grantors.  For notice purposes,
         Grantor will keep Lender informed at all times of Grantor's current
         address(es).

         POWER OF ATTORNEY.  Grantor hereby appoints Lender as its true and
         lawful attorney-in-fact, irrevocably, with full power of substitution
         to do the following:  (a) to demand, collect, receive, receipt for,
         sue and recover all sums of money or other property which may now or
         hereafter become due, owing or payable from the Collateral; (b) to
         execute, sign and endorse any and all claims, instruments, receipts,
         checks, drafts or warrants issued in payment for the Collateral; (c)
         to settle or compromise any and all claims arising under the
         Collateral, and, in the place and stead of Grantor, to execute an
         deliver its release and settlement for the claim; and (d) to file any
         claim or claims or to take any action or institute or take part in any
         proceedings, either in its own name or in the name of Grantor, or
         otherwise, which in the discretion of Lender may seem to be necessary
         or advisable.  This power is given as security for the Indebtedness,
         and the authority hereby conferred is and shall be irrevocable and
         shall remain in full force and effect until renounced by Lender.

         SEVERABILITY.  If a court of competent jurisdiction finds any
         provision of this Agreement to be invalid or unenforceable as to any
         person or circumstance, such finding shall not render that provision
         invalid or unenforceable as to any other persons or circumstances.  If
         feasible, any such offending provision shall be deemed to be modified
         to be within the limits of enforceability or validity; however, if the
         offending provision cannot be so modified, it shall be stricken and
         all other provisions of this Agreement in all other respects shall
         remain valid and enforceable.

         SUCCESSOR INTERESTS.  Subject to the limitations set forth above on

         inure to the benefit of the parties, their successors and assigns.

         WAIVER.  Lender shall not be deemed to have waived any rights under
         this Agreement unless such waiver is given in writing and signed by
         Lender.  No delay or omission on the part of Lender in exercising any
         right shall operate as a waiver of such right or any other right.  A
         waiver by Lender of a provision of this Agreement shall not





                                       12
   13

         prejudice or constitute a waiver of Lender's right otherwise to demand
         strict compliance with that provision or any other provision of this
         Agreement.  No prior waiver by Lender, nor any course of dealing
         between Lender and Grantor, shall constitute a waiver of any of
         Lender's rights or of any of Grantor's obligations as to any future
         transactions.  Whenever the consent of Lender is required under this
         Agreement, the granting of such consent by Lender in any instance
         shall not constitute continuing consent to subsequent instances where
         such consent is required and in all cases such consent may be granted
         or withheld in the sole discretion of Lender.
