SECTION 2.  CREDIT FACILITY

     2.1.  THE LOANS.  Provided that no Default or Event of Default has
occurred, Lender will make Loans on a revolving credit basis to Borrower from
time to time, in amounts as requested by Borrower, up to a maximum principal
amount at any time outstanding equal to the Borrowing Base at such time.  It is
expressly understood and agreed that Lender may use the Borrowing Base as a
maximum ceiling on Loans outstanding to Borrower at any time.  If the unpaid
balance of the Loans should exceed the Borrowing Base or any other limitation
set forth in this Agreement, such Loans shall nevertheless constitute
obligations that are secured by the Collateral and entitled to all benefits
thereof.  Insofar as Borrower may request and Lender may be willing in its
discretion to make Loans to Borrower at a time when the unpaid balance of Loans
exceeds, or would exceed with the making of any such Loan, the Borrowing Base
(any such Loan or Loans being herein referred to individually as an
"Overadvance" and collectively as "Overadvances"), Lender shall enter such
Overadvances as debits in the Loan Account.  All Overadvances shall be repaid ON
DEMAND.  In consideration of Lender making any Overadvance to Borrower, Borrower
agrees to pay to Lender, contemporaneously with the making of such Overadvance,
an amount equal to one percent (1%) of the Overadvance, provided that the
payment of such amount does not cause the interest on the obligations to exceed
the Maximum Legal Rate.  The Loans shall be used solely (i) for the satisfaction
of existing Indebtedness of Borrower to F&M Bank and Trust Company of Tulsa,
Oklahoma, (ii) for the satisfaction of certain trade payables and other
unsecured indebtedness owed to trade creditors of Borrower, (iii) for Borrower's
general operating capital needs to the extent not inconsistent with the
provisions of this Agreement, and (iv) for the payment of any of the fees
specified in Section 3.2 of this Agreement and, to the extent approved by
Lender, to the payment of any costs associated with the closing of the
transactions contemplated by this Agreement.

     2.2.  ALL LOANS TO CONSTITUTE ONE OBLIGATION.  All Loans shall constitute
one general obligation of Borrower, and shall be secured by Lender's security
interest in and Lien upon all of the Collateral, and by all other security
interests and Liens heretofore, now or at any time or times hereafter granted by
Borrower to Lender.

     2.3.  LOAN ACCOUNT.  Lender shall enter all Loans as debits to the Loan
Account and shall also record in the Loan Account all payments made by Borrower
on any Obligations and all proceeds of Collateral which are finally paid to
Lender, and may record therein, in accordance with customary accounting
practice, other debits and credits, including all charges and expenses properly
chargeable to Borrower and any other Obligation.

     2.4.  INCREASED COSTS AND CAPITAL.

     (A) If either (i) the introduction of or any change (including, without
limitation, any change by way of imposition or increase of reserve requirements)
in or in the interpretation of any law or regulation or (ii) the compliance by
Lender with any guideline or request from any central bank or other governmental
authority (whether or not having the force of law), shall result in any increase
in the cost to Lender of making, funding or maintaining any Loans, then Borrower
agrees to pay, from time to time, upon demand by Lender, to Lender additional
amounts sufficient to indemnify Lender against such increased cost.  A
certificate as to the amount of such increased cost, submitted to Borrower by
Lender, shall in the absence of manifest error, be conclusive.

     (B) If either (i) the introduction of or any change in or in the
interpretation of any law or regulation or (ii) compliance by Lender with any
guideline or request from any central bank or other governmental authority
(whether or not having the force of law) affects or would affect the amount of
capital required or expected to be maintained by Lender and Lender determines
that the amount of such capital is increased by or based upon the existence of
Lender's commitment to lend hereunder and other commitments of this type, then,
upon demand by Lender, Borrower shall immediately pay to Lender, from time to
time as specified by Lender, additional amounts sufficient to compensate Lender
in the light of such circumstances, to the extent that Lender reasonably
determines such increase in capital to be allocable to the existence of Lender's
commitment to lend hereunder.  A certificate as to such amounts, submitted to
Borrower by Lender, shall, in the absence of manifest error, be conclusive and
binding for all purposes.

     (C) Notwithstanding anything contained herein to the contrary, in the event
that Lender makes demand on Borrower pursuant to Section 2.4(A) or (B) hereof
for the payment of any additional amounts as specified therein, Borrower may,
within ninety (90) days following the date of the delivery by Lender of the
certificate(s) described in Section 2.4(A) or (B) hereof, at Borrower's option,
terminate this Agreement upon ten (10) days prior written notice to Lender.
Upon the effective date of such termination, Borrower shall pay to Lender the
then outstanding principal, accrued interest and other charges owing under this
Agreement and any of the other Agreements, and the termination charges or
prepayment premium provided for in Section 3.3(C) of this Agreement shall not be
payable as a result of Borrower's termination pursuant to this Section 2.4(C).

SECTION 3.  INTEREST, FEES, TERM AND REPAYMENT

     3.1.  INTEREST AND CHARGES.

     (A) Subject to subsection (D) of this Section 3.1, interest shall accrue on
the principal amount of the Loans outstanding at the end of each day at a
fluctuating rate per annum equal to one and one-half percent (1.50%) above the
Base Rate.

     (B) After the date hereof, the Applicable Rate shall be increased or
decreased, as the case may be, by an amount equal to any increase or decrease in
the Base Rate, with such adjustments to be effective as of the opening of
business on the day that any such change in the Base Rate becomes effective.
The Base Rate in effect on the date hereof shall be the Base Rate effective as
of the opening of business on the date hereof, but if this Agreement is executed
on a day that is not a Business Day, the Base Rate in effect on the date hereof
shall be the Base Rate effective as of the opening of business on the last
Business Day immediately preceding the date hereof.  Interest on the unpaid
principal balance of the obligations shall be calculated on a daily basis
(computed on the actual number of days elapsed over a year of 360 days or, for
the purposes of determining interest at the Maximum Legal Rate, a year of 365 or
366 days, as applicable), commencing on the date hereof, and shall be payable
monthly, in arrears, on the first day of each month.

     (C) Subject to subsection (D) of this Section 3.1, upon and after the
occurrence of an Event of Default, and during the continuation thereof, the
principal amount of the obligations shall bear interest, calculated daily
(computed on the actual days elapsed over a year of 360 days), at a fluctuating
rate per annum equal to two percent (2%) above the Applicable Rate set forth in
Section 3.1(A) (the "Default Rate").

     (D) Notwithstanding the foregoing, (i) if at any time the amount of such
interest computed on the basis of the Applicable Rate would exceed the amount of
such interest computed upon the basis of the maximum rate of interest permitted
by applicable state or federal law in effect from time to time hereafter (the
"Maximum Legal Rate"), the interest payable under this Agreement shall be
computed upon the basis of the Maximum Legal Rate, but any subsequent reduction
in the Applicable Rate shall not reduce such interest thereafter payable
hereunder below the amount computed on the basis of the Maximum Legal Rate until
the aggregate amount of such interest accrued and payable under this Agreement
equals the total amount of interest which would have accrued if such interest
had been at all times computed solely on the basis of the Applicable Rate; and
(ii) unless preempted by federal law, the Applicable Rate from time to time in
effect hereunder may not exceed the "Indicated Rate Ceiling" from time to time
in effect


                                     -15-

under Section (c) of Article 5069-1.04, Title 79, Revised Civil Statutes of
Texas, 1925, as amended.

     (E) No agreements, conditions, provisions or stipulations contained in this
Agreement or any other instrument, document or agreement between Borrower and
Lender or default of Borrower, or the exercise by Lender of the right to
accelerate the payment of the maturity of principal and interest, or to exercise
any option whatsoever contained in this Agreement or any other agreement between
Borrower and Lender, or the arising of any contingency whatsoever, shall entitle
Lender to collect, in any event, interest exceeding the Maximum Legal Rate and
in no event shall Borrower be obligated to pay interest exceeding such Maximum
Legal Rate and all agreements, conditions or stipulations, if any, which may in
any event or contingency whatsoever operate to bind, obligate or compel Borrower
to pay a rate of interest exceeding the Maximum Legal Rate, shall be without
binding force or effect, at law or in equity, to the extent only of the excess
of interest over such Maximum Legal Rate.  In the event any interest is charged
in excess of the Maximum Legal Rate ("Excess"), Borrower acknowledges and
stipulates that any such charge shall be the result of an accident and bona fide
error, and such Excess shall be, first, applied to reduce the principal then
unpaid hereunder; second, applied to reduce the obligations; and third, returned
to Borrower, it being the intention of the parties hereto not to enter at any
time into a usurious or otherwise illegal relationship.  Borrower recognizes
that, with fluctuations in the Applicable Rate and the Maximum Legal Rate, such
an unintentional result could inadvertently occur.  By the execution of this
Agreement, Borrower covenants that (i) the credit or return of any Excess shall
constitute the acceptance by Borrower of such Excess, and (ii) Borrower shall
not seek or pursue any other remedy, legal or equitable, against Lender, based
in whole or in part upon the charging or receiving of any interest in excess of
the maximum authorized by applicable law.  For the purpose of determining
whether or not any Excess has been contracted for, charged or received by
Lender, all interest at any time contracted for, charged or received by Lender
in connection with this Agreement, shall be amortized, prorated, allocated and
spread in equal parts during the entire term of this Agreement.

     (F) The provisions of Section 3.1(E) shall be deemed to be incorporated
into every document or communication relating to the obligations which sets
forth or prescribes any account, right or claim or alleged account, right or
claim of Lender with respect to Borrower (or any other obligor in respect of the
obligations), whether or not any provision of Section 3.1(E) is referred to
therein. All such documents and communications and all figures set forth therein
shall, for the sole purpose of computing the extent of the obligations and other
obligations of Borrower (or other obligor) asserted by Lender thereunder, be
automatically recomputed by Borrower or such obligor, and by any court
considering the same,


                                      -16-
<PAGE>
 
to give effect to the adjustments or credits required by Section 3.1(E).

     (G) If the applicable state or federal law is amended in the future to
allow a greater rate of interest to be charged under this Agreement or the other
Agreements than is presently allowed by applicable state or federal law, then
the limitation of interest hereunder shall be increased to the maximum rate of
interest allowed by applicable state or federal law as amended, which increase
shall be effective hereunder on the effective date of such amendment, and all
then accrued interest owing to Lender by reason thereof shall be payable UPON
DEMAND.

     (H) So long as no Default has occurred, in the event that Borrower achieves
the performance factors described below as of each of the calculation dates
specified below, then the Applicable Rate shall be reduced as follows:

     (i) Performance Factors to be Achieved as of October 31, 1991.  So long as
no Default has occurred, and so long as Borrower achieves the performance
factors set out below, upon the later of (i) receipt and review by Lender of
audited financial statements of Borrower provided pursuant to Section 9.1(J)
demonstrating compliance with the following performance factors, or (ii) receipt
by Lender of Borrower's Annual Business Plan for the twelve months ending
October 31, 1992, the Applicable Rate shall be reduced by 0.125%.  Such
reduction shall be made effective November 1, 1991 by (a) crediting the Loan
Account by the difference between the amount of interest paid by Borrower to
Lender since such effective date and the amount of interest which would have
been paid by Borrower to Lender since such effective date had the Applicable
Rate been so reduced, and (b) recalculating all accrued but unpaid interest, and
all interest to accrue with respect to future transactions, at the Applicable
Rate as so reduced.  The performance factors required to be achieved as of
October 31, 1991 in order to reduce the Applicable Rate are as follows:

     (A) The Average Daily Availability for the six months ending October 31,
1991 shall equal or exceed twenty-five percent (25%) of the Average Daily Loan
Balance for such period;

     (B) The Adjusted Net Earnings From Operations, plus taxes (to the extent
deducted therefrom), for the year ending October 31, 1991 shall be at least
$2,800,000; and

     (C) Borrower's Leverage Ratio as of October 31, 1991 shall not exceed 3.4
to 1.0.



                                      -17-
<PAGE>
 
Any rate reduction made pursuant to this Section 3.1(H)(i) shall remain in
effect only for so long as no Default has occurred and is continuing and
Borrower maintains the Leverage Ratio described in (C) above.

     (ii)     Performance Factors to be Achieved as of October 31, 1992. So long
as no Default has occurred, and so long as Borrower achieves the performance
factors set out below, upon the later of (i) receipt and review by Lender of
audited financial statements of Borrower provided pursuant to Section 9.1(J)
demonstrating compliance with the following performance factors, or (ii) receipt
by Lender of Borrower's Annual Business Plan for the twelve months ending
October 31, 1993, the Applicable Rate (as the same may or may not have been
reduced pursuant to Section 3.1(H)(i) above) shall be reduced by 0.25%. Such
reduction shall be made effective November 1, 1992 by (a) crediting the Loan
Account by the difference between the amount of interest paid by Borrower to
Lender since such effective date and the amount of interest which would have
been paid by Borrower to Lender since such effective date had the Applicable
Rate been so reduced, and (b) recalculating all accrued but unpaid interest, and
all interest to accrue with respect to future transactions, at the Applicable
Rate as so reduced. The performance factors required to be achieved as of
October 31, 1992 in order to reduce the Applicable Rate are as follows:

          (A) The Average Daily Availability for the months ending October 31,
     1992 shall equal or exceed twenty-five percent (25%) of the Average Daily
     Loan Balance for such period;

          (B) The Adjusted Net Earnings From operations, plus taxes (to the
     extent deducted therefrom), for the year ending October 31, 1992 shall be
     at least $2,500,000; and

          (C) Borrower's Leverage Ratio as of October 31, 1992 shall not exceed
     3.3 to 1.0.

Any rate reduction made pursuant to this Section 3.1(H)(ii) shall remain in
effect only for so long as no Default has occurred and is continuing and
Borrower maintains the Leverage Ratio described in (C) above.

     (iii)    Performance Factors to be Achieved by as of April 30, 1993. So
long as no Default has occurred, Borrower achieves the performance factors
described below, and the Applicable Rate has been and remains reduced pursuant
to each of Section 3.1(H)(i) and (ii) above, upon review and analysis by Lender
of the results of financial performance of Borrower for the period ending April
30, 1993 demonstrating compliance with the following performance factors, the
Applicable Rate


                                      -18-
<PAGE>
 
shall be further reduced by 0.125%.  Such reduction shall be made effective
May 1, 1993 by (a) crediting the Loan Account by the difference between the
amount of interest paid by Borrower to Lender since such effective date and the
amount of interest which would have been paid by Borrower to Lender since such
effective date had the Applicable Rate been so reduced, and (b) recalculating
all accrued but unpaid interest, and all interest to accrue with respect to
future transactions, at the Applicable Rate as so reduced.  The performance
factors required to be achieved as of April 30, 1993 in order to reduce the
Applicable Rate are as follows:

          (A) The Average Daily Availability for the six months ending April 30,
     1993 shall equal or exceed twenty-five percent (25%) of the Average Daily
     Loan Balance for such period;

          (B) The Adjusted Net Earnings From operations, plus taxes (to the
     extent deducted therefrom), for the six months ending April 30, 1993 shall
     be at least $1,250,000; and

          (C) Borrower's Leverage Ratio as of April 30, 1993 shall not exceed
     3.2 to 1.0.

Any rate reduction made pursuant to this Section 3.1(H)(iii) shall remain in
effect only for so long as no Default has occurred and is continuing and
Borrower maintains the Leverage Ratio described in (C) above.  In addition, in
the event that following any reduction in the Applicable Rate pursuant to this
Section 3.1(H)(iii), Borrower's annual audited financial statements delivered to
Lender pursuant to this Agreement reflect that Borrower was not entitled to such
reduction (notwithstanding that Borrower's unaudited financial statements
reflected that Borrower was entitled to such reduction), then Borrower shall (i)
immediately pay to Lender the difference between (a) the amount of interest paid
by Borrower to Lender since the date of the reduction of the Applicable Rate,
and (b) the amount of interest which would have been paid by Borrower to Lender
if the Applicable Rate had not been reduced, and (ii) the Applicable Rate shall
be immediately increased by 0.125% per annum with respect to all future
transactions.

     3.2. FEES.

          (A) Closing Fee. Borrower shall pay to Lender a closing fee of
$125,000, which shall be deemed fully earned and nonrefundable at the closing of
the transactions contemplated hereby and shall be paid concurrently with the
initial Loan hereunder. Such fee shall compensate Lender for the costs
associated with the origination, structuring, processing, approving and closing
of the transactions contemplated by this Agreement, including, but not limited
to, administrative, out-of-pocket,

                                      -19-
<PAGE>
 
general overhead and lost opportunity costs, but not including any expenses for
which Borrower has agreed to reimburse Lender pursuant to any other provision of
this Agreement (for example, reasonable attorney's fees incurred by Lender) or
any other Agreement.

          (B) Audit Fee. Borrower agrees to pay to Lender an audit fee payable
on a semiannual basis beginning on November 1, 1991 and continuing regularly
thereafter on the first day of each six-month period during the term of this
Agreement and upon termination hereof. The audit fee payable at any date shall
equal $2,000 plus all out of pocket costs and expenses incurred by Lender during
the preceding six month period in connection with administering the Loans,
provided the audit fee paid in any twelve-month period shall not exceed
$5,000.00 and shall not at any time be equal to or in excess of the amount which
would cause the interest on the obligations to exceed the Maximum Legal Rate.
This fee shall compensate Lender for certain aspects of administering the Loans,
including, without limitation, certain internal audits, appraisals and
collateral monitoring functions deemed necessary or appropriate by Lender, but
shall not include any expenses for which Borrower has agreed to reimburse Lender
pursuant to any other provision of this Agreement or any Other Agreement.

          (C) Unused Facility Fee. Borrower agrees to pay to Lender a quarterly
unused facility fee, equal to one-half percent (0.50%) per annum of the average
daily unused portion of the Commitment, payable quarterly in arrears, beginning
August 1, 1991 and continuing regularly thereafter during the term of this
Agreement and upon the termination hereof.

     3.3. TERM OF AGREEMENT; TERMINATION.

          (A) The provisions of this Agreement shall be in effect for a period
of three (3) years from the date hereof, through and including May 3, 1994 (the
"Original Term"), unless terminated as provided in Section 3.3(B) hereof, or
extended pursuant to this Section 3.3(A). So long as no Default has occurred,
the original Term shall be automatically extended by one (1) year unless
Borrower has notified Lender, or Lender has notified Borrower, on or before
January 3, 1994, that it does not desire this Agreement to be extended pursuant
to this Section 3.3(A).

          (B) Upon at least ninety (9O) days prior written notice to Lender,
Borrower may, at its option, terminate this Agreement; provided, however, no
such termination shall be effective until Borrower has paid all of the
obligations in immediately available funds, together with the termination charge
or prepayment premium provided for in Section 3.3(C) hereof, if any. It is
understood that Borrower may elect to terminate this Agreement in its entirety
only; no section or lending facility may be terminated singly. Lender may
terminate this Agreement without notice upon or after the occurrence of an Event
of Default.

                                      -20-
<PAGE>
 
          (C) At the effective date of such termination by Borrower, Borrower
shall pay to Lender (in addition to the then outstanding principal, accrued
interest and other charges, fees and expenses owing under this Agreement and any
of the other Agreements), as liquidated damages for the loss of the bargain and
not as a penalty, an amount equal to the applicable percentage set forth below
of the highest of the Average Daily Loan Balances outstanding for any month
during the applicable term set forth below during which such termination occurs:

     Applicable Term              Applicable Percentage
     ---------------              ---------------------

     The date hereof through                 3%
       May 2, 1992

     May 3, 1992, through                    2%
       May 2, 1993

     May 3, 1993, through                    1%
       May 2, 1994

     Thereafter                              0%

If termination occurs on the last day of the original Term, Borrower shall not
be obligated to pay Lender any liquidated damages.

          (D) All of the obligations shall be forthwith due and payable upon any
termination of this Agreement.  Except as otherwise expressly provided for in
this Agreement or any of the other Agreements, no termination or cancellation
(regardless of cause or procedure) of this Agreement or any of the other
Agreements shall in any way affect or impair the powers, obligations, duties,
rights, and liabilities of Borrower or Lender in any way relating to (i) any
transaction or event occurring prior to such termination or cancellation or (ii)
any of the undertakings, agreements, covenants, warranties or representations of
Borrower contained in this Agreement or any of the other Agreements. All such
undertakings, agreements, covenants, warranties and representations shall
survive such termination or cancellation and Lender shall retain its Liens in
the Collateral, and all of its rights and remedies under this Agreement and the
other Agreements notwithstanding such termination or cancellation, until
Borrower has paid the obligations to Lender, in full, in immediately available
funds.

     3.4.  PAYMENTS.  Except where evidenced by notes or other instruments
issued or made by Borrower to Lender specifically containing payment provisions
which are in conflict with this Section 3.4 (in which event the conflicting
provisions of said notes or other instruments shall govern and control), that
portion of the obligations consisting of:

                                      -21-
<PAGE>
 
          (A) Principal, payable on account of Loans made by Lender to Borrower,
shall be payable by Borrower to Lender immediately upon the earliest of (i) the
occurrence of an Event of Default in consequence of which Lender elects to
accelerate the maturity and payment of the Obligations, or (ii) termination of
this Agreement pursuant to Section 3.3 hereof; provided, however, that if the
principal balance of Loans outstanding at any time shall exceed the Borrowing
Base at such time, Borrower shall, ON DEMAND, repay the Loans in an amount
sufficient to reduce the aggregate unpaid principal amount of such Loans by an
amount equal to such excess;

          (B) Interest accrued on the obligations shall be due on the earliest
of (i) the first day of each month (for the immediately preceding month),
computed through the last calendar day of the preceding month, (ii) the
occurrence of an Event of Default in consequence of which Lender elects to
accelerate the maturity and payment of the obligations or (iii) termination of
this Agreement pursuant to Section 3.3 hereof; provided, however, that Borrower
hereby irrevocably authorizes Lender, in Lender's sole discretion, to advance to
Borrower, and to charge to the Loan Account hereunder as a Loan, a sum
sufficient each month to pay all interest accrued on the obligations during the
immediately preceding month; and

          (C) The remainder of the obligations requiring the payment of money,
if any, shall be payable by Borrower to Lender as and when provided in this
Agreement or the other Agreements.

     3.5.  APPLICATION OF PAYMENTS AND COLLECTIONS.  Borrower irrevocably waives
the right to direct the application of any and all payments and collections at
any time or times hereafter received by Lender from or on behalf of Borrower,
and Borrower hereby irrevocably agrees that Lender shall have the continuing
exclusive right to apply and reapply any and all such payments and collections
received at any time or times hereafter by Lender or its agent against the
obligations, in such manner as Lender may deem advisable, notwithstanding any
entry by Lender upon any of its books and records.  If as the result of
collections of Accounts as authorized by Section 5.2 hereof, a credit balance
exists in the Loan Account, such credit balance shall not accrue interest in
favor of Borrower, but shall be available to Borrower at any time or times for
so long as no Default or Event of Default exists.

     3.6.  STATEMENTS OF ACCOUNT.  Lender will account to Borrower monthly with
a statement of Loans, charges and payments made pursuant to this Agreement, and
such account rendered by Lender shall be deemed final, binding and conclusive
upon Borrower, unless Lender is notified by Borrower in writing to the contrary
within thirty (30) days of the date each account was rendered.  Such notice
shall only be deemed an objection to those items specifically objected to
therein.

SECTION 4.  COLLATERAL: GENERAL TERMS

     4.1.   SECURITY INTEREST IN COLLATERAL.  To secure the prompt payment and
performance to Lender of the Obligations, Borrower hereby grants to Lender a

Property of Borrower, whether now owned or existing or hereafter created,
acquired or arising and wheresoever located, including, without limitation, the
following Property and interests in Property:

            (A)  Accounts;

            (D)  General Intangibles;

            (E) All monies and other Property of any kind, now or at any time or
times hereafter, in the possession or under the control of Lender or a bailee of
Lender;

insurance policies insuring any of the Collateral; and

            (G) All books and records (including, without limitation, customer

and records) of Borrower pertaining to any of (A), (B), (C), (D), (E) or (F)
above.

     4.2.   FINANCING STATEMENTS; WARRANTIES REGARDING PRIORITY OF THE LIENS OF
LENDER IN THE COLLATERAL.

            (A) Borrower agrees to execute the financing statements provided for
by the Code and by Chapter 9, together with any and all other instruments,
assignments or documents, and shall take such other action as may be required to
create, perfect or to continue the perfection of Lender's security interest in
the Collateral. Unless prohibited by applicable law, Borrower hereby authorizes
Lender to execute and file any such financing statement on Borrower's behalf.
The parties agree that a carbon, photographic or other reproduction of this
Agreement shall be sufficient as a financing statement and may be filed in any
appropriate office in lieu thereof.

          (B) Borrower is the owner of full legal and equitable title to the
Collateral, free and clear of any Liens, except Permitted Liens, and, other than
in connection with Permitted Liens, no financing statement covering the
Collateral or any part

                                      -23-
<PAGE>
 
or proceeds thereof is on file in any public office, and the execution by
Borrower of this Agreement and the other Agreements to which it is a party and
the filing of the relevant financing statements in the appropriate jurisdictions
will create in favor of the Lender a valid, perfected first Lien against the
Collateral, subject to the Permitted Liens.

     4.3.  LOCATION OF COLLATERAL.  All Collateral, other than Inventory in
transit and motor vehicles, will at all times be kept by Borrower at one or more
of the business locations set forth in Exhibit "A" and shall not, without the
prior written approval of Lender, be moved therefrom except, prior to an Event
of Default and Lender's acceleration of the maturity of the obligations in
consequence thereof, for sales of Inventory in the ordinary course of business,
dispositions of Equipment that are authorized by Section 7.2 hereof and
Inventory and Equipment in transit from one business location to another.

     4.4.  INSURANCE OF COLLATERAL.  Borrower agrees to maintain and pay for
insurance upon such of the Tangible Collateral as shall be required by Lender,
wherever located, in storage or in transit in vehicles, including goods
evidenced by documents, covering casualty, hazard, public liability and such
other risks and in such amounts and with such insurance companies as shall be
reasonably satisfactory to Lender to insure Lender's interest in the Collateral.
Borrower shall deliver certificates for such policies to Lender with
satisfactory lender's loss payable endorsements naming Lender loss payee.  Each
policy of insurance or endorsement shall contain a clause requiring the insurer
to give not less than thirty (30) days prior written notice to Lender in the
event of cancellation of the policy for any reason whatsoever and a clause, if
such a clause is permitted in policies issued in the State of Texas, that the
interest of Lender shall not be impaired or invalidated by any act or neglect of
Borrower or owner of the Property nor by the occupation of the premises for
purposes more hazardous than are permitted by said policy.  If Borrower fails to
provide and pay for such insurance, Lender may, at Borrower's expense, procure
the same, but shall not be required to do so. Borrower agrees upon request by
Lender, to deliver to Lender, promptly as rendered, true copies of all reports
made in any reporting forms to insurance companies.

     4.5.  PROTECTION OF COLLATERAL.  Borrower shall pay and discharge when due
all claims to and levies and charges upon any of the Collateral. Lender may, at
any time or times hereafter, in its sole discretion, without waiving or
releasing any obligations, liability or duty of Borrower under this Agreement or
the other Agreements, or any Event of Default, pay when due, acquire or accept
an assignment of any Lien or claim asserted by any Person against any of the
Collateral; provided, however, as long as no Event of Default has occurred,
Lender shall notify Borrower if any single such payment will be in excess of
$5,000.  All sums paid by

                                      -24-
<PAGE>
 
Lender in respect thereof and all costs, fees and expenses, including, without
limitation, attorney's fees and court costs, which are incurred by Lender on
account thereof, shall be payable UPON DEMAND by Borrower to Lender, together
with interest accruing at the Default Rate from the date of demand until paid
and shall be secured by the Collateral.  Lender shall not be liable or
responsible in any way for the safekeeping of any of the Collateral or for any
loss or damage thereto or for any diminution in the value thereof, or for any
act or default of any warehouseman, carrier, forwarding agency, or other Person
whomsoever, but the same shall be at Borrower's sole risk.

SECTION 5.  PROVISIONS RELATING TO ACCOUNTS

     5.1.   REPRESENTATIONS, WARRANTIES AND COVENANTS.  With respect to all
Accounts, Borrower represents and warrants to Lender that Lender may rely, in
determining which Accounts are Eligible Accounts, on all statements and
representations made by Borrower with respect to any Account or Accounts, and,
unless otherwise indicated in writing to Lender, that with respect to each
Account:  it is genuine and in all respects what it purports to be, and it is
not evidenced by a judgment; it arises out of a completed, bona fide sale and
delivery of goods or rendition of services by Borrower in the ordinary course of
its business and in accordance with the terms and conditions of all purchase
orders, contracts or other documents relating thereto; it is for a liquidated
amount maturing as stated in the duplicate invoice covering such sale or
rendition of services; such Account, and Lender's security interest therein, is
not, and, to the best of Borrower's knowledge, will not be in the future,
subject to any offset, Lien, deduction, defense, dispute, counterclaim or any
other adverse condition, except for disputes resulting in returned goods where
the amount in controversy is deemed by Lender to be immaterial, and, to the best
of Borrower's knowledge, each such Account is absolutely owing to Borrower and
is not contingent in any respect or for any reason; Borrower has made no
agreement with any Account Debtor thereunder for any deduction therefrom, except
discounts or allowances which are granted by Borrower in the ordinary course of
its business for prompt payment; to the best of Borrower's knowledge, there are
no facts, events or occurrences which in any way impair the validity or
enforceability thereof or tend to reduce the amount payable thereunder from the
face amount of the invoice and statements delivered to Lender with respect
thereto; to the best of Borrower's knowledge, the Account Debtor thereunder (i)
had the capacity to contract at the time any contract or other document giving
rise to the Account was executed and (ii) such Account Debtor is Solvent; and
Borrower has no knowledge of any fact or circumstance which would impair the
validity or collectibility of the Account.

     5.2.   COLLECTION OF ACCOUNTS.  To expedite collection, Borrower shall
endeavor in the first instance to make collection of their Accounts for Lender.
All remittances received by Borrower on

                                      -25-
<PAGE>
 
account of Accounts shall be held as Lender's property by Borrower as trustee of
an express trust for Lender's benefit and Borrower shall deposit same in the
Dominion Account.  Lender retains the right, upon and after the occurrence of an
Event of Default, to notify Account Debtors that Accounts have been assigned to
Lender and to collect Accounts directly in its own name and to charge the
collection costs and expenses, including attorneys' fees, to Borrower.  Lender
has no duty to protect, insure, collect or realize upon the Accounts or preserve
rights in them.  For the purpose of computing interest hereunder, all items of
payment received by Lender shall be deemed applied by Lender on account of the
obligations (subject to final payment of such items) on the first Business Day
after Lender's withdrawal of such payment from the Dominion Account in
immediately available funds.  Whenever reasonably practicable, Lender shall
withdraw all funds contained in the Dominion Account on a daily basis, for
application of such funds to the payment of the obligations as provided herein.
Borrower shall deposit all proceeds of the Collateral or cause the same to be
deposited in kind in the Dominion Account pursuant to an arrangement with such
banks as may be selected by Borrower and be acceptable to Lender.  Borrower
shall deposit all payments or other remittances received by Borrower in their
operating accounts to the Dominion Account.  After the occurrence of an Event of
Default Lender may, and Borrower shall at Lender's request, notify Account
Debtors and all other parties obligated on the Collateral to make payments
directly to the Dominion Account.  All funds deposited in the Dominion Account
shall immediately become the Property of Lender, and Borrower shall obtain the
agreement by such banks to waive any offset rights against the funds so
deposited.  Lender assumes no responsibility for such account arrangement,
including, without limitation, any claim of accord and satisfaction or release
with respect to deposits accepted by any bank thereunder.

     5.3.   ADMINISTRATION OF ACCOUNTS.  Upon the granting of any discounts,
allowances or credits by Borrower that are not shown on the face of the invoice
for the Account involved, Borrower shall promptly report such discounts,
allowances or credits, as the case may be, to Lender and in no event later than
the time of its submission to Lender of the next Schedule of Accounts as
provided in Section 5.4.  If an Account includes a charge for any tax payable to
any governmental taxing authority, Lender is authorized, in its sole discretion,
to pay the amount thereof to the proper taxing authority for the account of
Borrower and to charge Borrower's Loan Account hereunder therefor.  Whether or
not a Default or an Event of Default has occurred, Lender shall have the right,
at any time or times hereafter, in the name of Lender, any designee of Lender or
Borrower, to verify the validity, amount or any other matter relating to any
Accounts, such verification to be in a format reasonably satisfactory to Lender
and Borrower or, if Lender decides, in its sole discretion, to use a different
format or method, such format or method regarding which Borrower shall have been
notified; provided, however, that after the occurrence of

                                      -26-
<PAGE>
 
an Event of Default, Lender shall have the right to determine, in its sole
discretion, the format and method for such verification without the obligation
of giving notice to the Borrower of the format and method decided upon by
Lender.  Borrower shall cooperate fully with Lender in an effort to facilitate
and promptly conclude any such verification process.

     5.4.   ASSIGNMENTS, RECORDS AND SCHEDULES OF ACCOUNTS.  Borrower shall keep
accurate and complete records of its Accounts and all payments and collections
thereon.  On or before the 20th day of each month from and after the date
hereof, Borrower shall deliver to Lender, in form acceptable to Lender, a
detailed aged trial balance of all Accounts existing as of the last day of the
preceding month, specifying the names, addresses, face value, dates of invoices
and due dates for each Account Debtor obligated on an Account so listed
("Schedule of Accounts"), along with, if requested by Lender, copies of proof of
delivery and the original copy of all documents, including, without limitation,
repayment histories and present status reports relating to the Accounts so
scheduled and such other matters and information relating to the status of then
existing Accounts as Lender shall reasonably request, and also with, if
requested by Lender, formal written assignments by Borrower to Lender of all of
Borrower's Accounts, together with copies of invoices or invoice registers
related thereto.  If any amounts due and owing in excess of $10,000 are in
dispute between Borrower and any Account Debtor, Borrower shall provide Lender
with written notice thereof at the time of submission of the next Schedule of
Accounts, explaining in detail the reason for the dispute, all claims related
thereto, and the amount in controversy.  In addition to and not in limitation of
the other provisions of this Section 5.4, if at any time a Default occurs,
Lender shall thereafter have the right to require that Borrower deliver to
Lender such other reports, information and materials regarding the Accounts as
shall be specified by Lender.

SECTION 6.  PROVISIONS RELATING TO INVENTORY

     6.1.   REPRESENTATIONS, WARRANTIES AND COVENANTS.  With respect to
Inventory, Borrower represents and warrants to Lender that Lender may rely, in
determining which items of Inventory constitute Eligible Inventory, on all
statements and representations made by Borrower with respect to any Inventory
and, unless otherwise indicated in writing to Lender, that:  all Inventory is
presently and will continue to be located at Borrower's places of business
listed on Exhibit "A" and will not be removed therefrom, except as authorized by
Section 4.3 of this Agreement; no Inventory is now, nor shall any Inventory at
any time or times hereafter be, stored with a bailee, warehouseman or similar
party unless (i) Lender shall have granted its prior written consent thereto,
(ii) such bailee, warehousemen or similar party shall have delivered to Lender a
warehousemen's letter in the form requested by Lender, and (iii) all original
warehouse receipts or other documents relating

                                      -27-
<PAGE>
 
to such Inventory shall have been delivered to Lender; and no Inventory is or
will be sold by consignment by any Person without Lender's prior written
consent, except as otherwise disclosed on Exhibit "A".

     6.2.   INVENTORY REPORTS. On or before the 20th day of each month from and
after the date hereof, Borrower agrees to furnish Lender with Inventory reports.
Such reports shall be in form and detail satisfactory to Lender.  Borrower shall
conduct such physical inventory tests as are acceptable to the independent
certified public accountants of Borrower who are preparing the financial
statements referred to in Section 9.1(J) and Borrower shall provide to Lender,
upon request by Lender, an annual report regarding their physical inventory
based upon such testing procedures, as well as copies of any other inventory
tests conducted by or on behalf of Borrower, together with such supporting
information as Lender shall, in its discretion, request.  In addition to and not
in limitation of the other provisions of this Section 6.2, if at any time a
Default occurs, Lender shall thereafter have the right to require that Borrower
deliver to Lender such other reports, information and materials regarding the
Inventory as shall be specified by Lender.

     6.3.   RETURNS OF INVENTORY.  If at any time or times hereafter any Account
Debtor returns any Inventory with a cost or market value in excess of $10,000 to
Borrower, Borrower shall notify Lender of the same immediately, specifying the
reason for such return and the location and condition of the returned Inventory.

SECTION 7.  PROVISIONS RELATING TO EQUIPMENT

     7.1.   REPRESENTATIONS, WARRANTIES AND COVENANTS.  With respect to the
Equipment, Borrower represents, warrants and covenants to and with Lender that
Borrower has good and marketable title to the Equipment, that the Equipment is
in good operating condition and repair, and all necessary replacements of and
repairs thereto shall be made so that the value and operating efficiency of the
Equipment shall be maintained and preserved, reasonable wear and tear excepted.
Borrower will not permit any of the Equipment to become affixed to any real
Property leased to Borrower, so that an interest arises therein under the real
estate laws of the applicable jurisdiction, unless the landlord of such real
Property has executed a landlord waiver in favor of Lender, and Borrower will
not permit any of the Equipment to become an accession to any personal Property,
other than Equipment subject to first priority Liens in favor of Lender, subject
only to Permitted Liens.  Immediately on request therefor by Lender, Borrower
shall deliver to Lender any and all evidence of ownership, if any, of any of the
Equipment (including, without limitation, certificates of title and applications
for title).  Borrower shall maintain accurate records itemizing and describing
the kind, type, quality, quantity and value of its Equipment and all
dispositions made in accordance with

                                      -28-
<PAGE>
 
Section 7.2 hereof, and shall furnish Lender with a current schedule containing
the foregoing information on at least an annual basis and more often if
requested by Lender.

     7.2.   DISPOSITIONS OF EQUIPMENT.  Borrower will not sell, lease or
otherwise dispose of or transfer any of the Equipment or any part thereof
without the prior written consent of Lender; provided, however, that the
foregoing restriction on the sale, lease, disposition or other transfer of any
Equipment shall not apply, for so long as no Default or Event of Default exists,
to (i) dispositions of Equipment which, in the aggregate during any consecutive
twelve-month period, has a fair market value or book value, whichever is less,
of $100,000 or less, provided that all proceeds thereof are turned over to
Lender to be applied by Lender in accordance with Section 3.5 hereof, or (ii)
replacement of Equipment that is substantially worn, damaged or obsolete with
Equipment of like kind, function and value, provided that the replacement
Equipment shall be acquired prior to or concurrently with any disposition of the
Equipment that is to be replaced, the replacement Equipment shall be free and
clear of Liens, other than Permitted Liens, Borrower shall give Lender at least
five (5) days prior written notice of such disposition, and Borrower shall turn
over to Lender all proceeds realized from any such disposition to be applied by
Lender in accordance with Section 3.5 hereof.

stockholder of Borrower.

            (D) Guarantee, assume, endorse or otherwise, in any way, become
directly or contingently liable with respect to the Indebtedness of any Person,

Lender's Lien in the Collateral; (iii) Liens securing the claims or demands of
materialmen, mechanics, carriers, warehousemen, and other like Persons for
labor, materials or

operation of Borrower's business; (vi) Purchase Money Liens securing
indebtedness incurred for the payment of Capital Expenditures permitted by this
Agreement; (vii) reservations, exceptions, easements, rights of way, and other

has consented thereto; (viii) Liens permitted pursuant to the provisions of any
other Agreement; (ix) Landlord or warehouseman liens with respect to any
premises leased by Borrower or upon which Borrower's goods are stored, as long

the Financial Agreement.

            (G) Hereafter create any Subsidiary or divest itself of any material
assets by transferring them to any Subsidiary to whose existence Lender has

under executory process or other legal process, and consenting that the
Collateral be sold without appraisement, either in its entirety or in lots or
parcels, as Lender may determine, to the highest bidder for cash or on such
other terms as the plaintiff in such proceeding may direct. Furthermore, upon
the occurrence of an Event of Default, if Lender employs an attorney to enforce

     12.1.  POWER OF ATTORNEY. Borrower hereby irrevocably designates, makes,
constitutes and appoints Lender (and all Persons designated by Lender) as

agent, may, without notice to Borrower and in either Borrower's or Lender's
name, but at the cost and expense of Borrower:

            (A) At such time or times hereafter as Lender or said agent, in its
sole discretion, may determine, endorse Borrower's name on any checks, notes,
acceptances, drafts, money orders or any other evidence of payment or proceeds
of the Collateral which come into the possession of Lender or under Lender's
control; and

            (B) At such time or times upon or after the occurrence of an Event
of Default as Lender or its agent in its sole

                                      -45-

discretion may determine: (i) enforce payment of the Accounts by legal
proceedings or otherwise and exercise generally all of Borrower's rights and
remedies with respect to the collection of the Accounts; (ii) settle, adjust,
compromise, discharge or release any of the Accounts or other Collateral or any
legal proceedings brought to collect any of the Accounts or other Collateral;
(iii) prepare, file and sign Borrower's name to a proof of claim in bankruptcy
or similar document against any Account Debtor or to any notice of lien,
assignment or satisfaction of lien or similar document in connection with any of
the Collateral; (iv) receive, open and dispose of all mail addressed to Borrower
and to notify postal authorities to change the address for delivery thereof to

bill, bill of lading or similar document or agreement relating to the Accounts,
Inventory and any other Collateral; (vii) use Borrower's stationery and sign the
name of Borrower to verifications of the Accounts and notices thereof to Account
Debtors; (viii) make and adjust claims under policies of insurance; and (ix) do
all other acts and things necessary, in Lender's determination, to fulfill
Borrower's obligations under this Agreement.

     12.2.  INDEMNITY. Borrower hereby agrees to indemnify Lender and hold
Lender harmless from and against any liability, loss, damage, suit, action or
proceeding ever suffered or incurred by Lender as the result of Borrower's
operation of its business or its failure to observe, perform or discharge
Borrower's duties hereunder. Without limiting the generality of the foregoing,
this indemnity shall extend to any claims asserted against Lender by any Person
under any Environmental Laws or similar laws by reason of Borrower's or any
other Person's failure to comply with laws applicable to solid or hazardous
waste materials or other toxic substances. The obligation of Borrower under this
Section 12.2 shall survive the payment in full of the obligations and the
termination of this Agreement.

     12.3.  MODIFICATION OF AGREEMENT: SALE OF INTEREST. This Agreement may not
be modified, altered or amended, except by an agreement in writing signed by
Borrower and Lender. Borrower may not sell, assign or transfer any interest in
this Agreement or any of the other Agreements, or any portion thereof,
including, without limitation, Borrower's rights, title, interests, remedies,
powers, and duties hereunder or thereunder. Borrower hereby consents to Lender's
participation, sale, assignment, transfer or other disposition, at any time or
times hereafter, of this Agreement and any of the other Agreements, or of any
portion hereof or thereof, including, without limitation, Lender's rights,
title, interests, remedies, powers, and duties hereunder or thereunder.

     12.4.  REIMBURSEMENT OF EXPENSES. If, at any time or times prior or
subsequent to the date hereof, regardless of whether or not an Event of Default
then exists or any of the transactions contemplated hereunder are concluded,
Lender or any Participating Lender employs counsel for advice or other
representation, or incurs legal expenses or other costs or out-of-pocket
expenses in connection with: (A) the negotiation and preparation of this
Agreement or any of the other Agreements, any amendment of or modification of
this Agreement or any of the other Agreements, any consent or waiver granted by
Lender in connection with this Agreement or any of the other Agreements, or any
sale or attempted sale of any interest herein to a Participating Lender; (B) the
administration of this Agreement or any of the other Agreements and the
transactions contemplated hereby and thereby; (C) any litigation, contest,
dispute, suit, proceeding or action (whether instituted by Lender, Borrower or
any other Person) in any way relating to the Collateral, this Agreement or any
of the other Agreements or Borrower's affairs; (D) any attempt to enforce any
rights of Lender or any Participating Lender against Borrower or any other
Person which may be obligated to Lender by virtue of this Agreement or any of
the other Agreements, including, without limitation, the Account Debtors; or (E)
any attempt to inspect, verify, protect, preserve, restore, collect, sell,
liquidate or otherwise dispose of or realize upon the Collateral; then, in any
such event, the attorneys' fees arising from such services and all expenses,
costs, charges and other fees of such counsel or of Lender or relating to any of
the events or actions described in this Section shall be payable, ON DEMAND, by
Borrower to Lender or to such Participating Lender, as the case may be, and
shall be additional obligations hereunder secured by the Collateral.
Additionally, if any taxes (excluding taxes imposed upon or measured by the net
income of Lender) shall be payable on account of the execution or delivery of
this Agreement, or the execution, delivery, issuance or recording of any of the
other Agreements, or the creation of any of the obligations hereunder, by reason
of any existing or hereafter enacted federal or state statute, Borrower will pay
all such taxes, including, but not limited to, any interest and penalties
thereon, and will indemnify and hold Lender harmless from and against liability
in connection therewith. Borrower hereby irrevocably authorizes Lender to enter
any and all expenses or other amounts owing to Lender by Borrower pursuant to
this Section 12.4 as debits in the Loan Account.

     12.5.  INDULGENCES NOT WAIVERS. Lender's failure, at any time or times
hereafter, to require strict performance by Borrower of any provision of this
Agreement shall not waive, affect or diminish any right of Lender thereafter to
demand strict compliance and performance therewith. Any suspension or waiver by
Lender of an Event of Default under this Agreement or any of the other
Agreements shall not suspend, waive or affect any other Event of Default under
this Agreement or any of the other Agreements,


                                      -47-

whether the same is prior or subsequent thereto and whether of the same or of a
different type.

     12.6.  SEVERABILITY. Wherever possible, each provision of this Agreement
shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement shall be prohibited by or
invalid under applicable law, such provision shall be ineffective only to the
extent of such prohibition or invalidity, without invalidating the remainder of
such provision or the remaining provisions of this Agreement.

     12.7.  SUCCESSORS AND ASSIGNS. This Agreement and the other Agreements
shall be binding upon and inure to the benefit of the successors and assigns of
Borrower and Lender. This provision, however, shall not be deemed to modify
Section 12.3 hereof.

     12.8.  CUMULATIVE EFFECT: CONFLICT OF TERMS. The provisions of the other
Agreements are hereby made cumulative with the provisions of this Agreement.
Except as otherwise provided in Section 3.4 of this Agreement and except as
otherwise provided in any of the other Agreements by specific reference to the
applicable provision of this Agreement, if any provision contained in this
Agreement is in direct conflict with, or inconsistent with, any provision in any
of the other Agreements, the provision contained in this Agreement shall govern
and control.

number of counterparts and by different parties hereto in separate counterparts,
each of which when so executed and delivered shall be deemed to be an original
