SECTION 2.  CREDIT FACILITIES

  2.1  Revolving Loans.

       (a)  Subject to, and upon the terms and conditions
contained herein, Lender agrees to make Revolving Loans to Borrower
from time to time in amounts requested by Borrower up to the amount
equal to the sum of:  

                    (i)  eighty percent (80%) of the Net Amount of
     Eligible Accounts, less 
     
                    (ii) the sum of:  (A) any Availability Reserves, (B)
     the Permanent Reserve, (C) the Judgment Reserve, and (D) the
     Licensing Payment Reserve.
     
       (b)  Lender may, in its good faith discretion, from time to
time, reduce the lending formula with respect to Eligible Accounts
to the extent that Lender determines in good faith that: (A) the
dilution with respect to the Accounts for any period (based on the
ratio of (1) the aggregate amount of reductions in Accounts other
than as a result of payments in cash to (2) the aggregate amount of
total sales) has increased in any material respect or may be
reasonably anticipated to increase in any material respect above
historical levels, or (B) the general creditworthiness of account
debtors has materially declined as determined by Lender in good
faith.  In determining whether to reduce the lending formula(s),
Lender may consider events, conditions, contingencies or risks
which are also considered in determining Eligible Accounts or in
establishing Availability Reserves.

       (c)  Except in Lender's discretion, the aggregate amount of
the Loans and the Letter of Credit Accommodations outstanding at
any time shall not exceed the Maximum Credit. In the event that the
outstanding amount of any component of the Loans, or the aggregate
amount of the outstanding Loans and Letter of Credit
Accommodations, exceed the amounts available under the lending
formulas, the sublimits for Letter of Credit Accommodations set
forth in Section 2.2(c) or the Maximum Credit, as applicable, such
event shall not limit, waive or otherwise affect any rights of
Lender in that circumstance or on any future occasions and Borrower
shall, upon demand by Lender, which may be made at any time or from
time to time, immediately repay to Lender the entire amount of any
such excess(es) for which payment is demanded.

                                  9
<PAGE>
  2.2  Letter of Credit Accommodations.

       (a)  Subject to, and upon the terms and conditions
contained herein, at the request of Borrower, Lender agrees to
provide or arrange for Letter of Credit Accommodations for the
account of Borrower containing terms and conditions acceptable to
Lender and the issuer thereof.  Any payments made by Lender to any
issuer thereof and/or related parties in connection with the Letter
of Credit Accommodations shall constitute additional Revolving
Loans to Borrower pursuant to this Section 2.

       (b)  In addition to any charges, fees or expenses charged
by any bank or issuer in connection with the Letter of  Credit
Accommodations, Borrower shall pay to Lender a letter of credit fee
at a rate equal to one and three quarters percent (1.75%) per annum
on the daily outstanding balance of the Letter of Credit
Accommodations for the immediately preceding month (or part
thereof), payable in arrears as of the first day of each succeeding
month.  Such letter of credit fee shall be calculated on the basis
of a three hundred sixty (360) day year and actual days elapsed and
the obligation of Borrower to pay such fee shall survive the
termination or non-renewal of this Agreement.

       (c)  No Letter of Credit Accommodations shall be available
unless on the date of the proposed issuance of any Letter of Credit
Accommodations, the Revolving Loans available to Borrower (subject
to the Maximum Credit and any Availability Reserves) are equal to
or greater than an amount equal to one hundred (100%) percent of
the face amount thereof and all other commitments and obligations
made or incurred by Lender with respect thereto. Effective on the
issuance of each Letter of Credit Accommodation, the amount of
Revolving Loans which might otherwise be available to Borrower
shall be reduced by the applicable amount set forth in this Section
2.2(c).

       (d)  Except in Lender's discretion, the amount of all
outstanding Letter of Credit Accommodations and all other
commitments and obligations made or incurred by Lender in
connection therewith, shall not at any one time exceed Five Hundred
Thousand Dollars ($500,000).  At any time an Event of Default
exists or has occurred and is continuing, upon Lender's request,
Borrower will either furnish cash collateral to secure the
reimbursement obligations to the issuer in connection with any
Letter of Credit Accommodations or furnish cash collateral to
Lender for the Letter of Credit Accommodations, and in either case,
the Revolving Loans otherwise available to Borrower shall not be
reduced as provided in Section 2.2(c) to the extent of such cash
collateral.

       (e)  Borrower shall indemnify and hold Lender harmless from
and against any and all losses, claims, damages, liabilities, costs
and expenses which Lender may suffer or incur in connection with
any Letter of Credit Accommodations and any documents, drafts or
acceptances relating thereto, including, but not limited to, any
losses, claims, damages, liabilities, costs and expenses due to any
action taken by any issuer or correspondent with respect to any
Letter of Credit Accommodation.  Borrower assumes all risks with
respect to the acts or omissions of the drawer under or beneficiary
of any Letter of Credit Accommodation and for such purposes the

                               10
<PAGE>
drawer or beneficiary shall be deemed Borrower's agent.  Borrower
assumes all risks for, and agrees to pay, all foreign, Federal,
State and local taxes, duties and levies relating to any goods
subject to any Letter of Credit Accommodations or any documents,
drafts or acceptances thereunder.  Borrower hereby releases and
holds Lender harmless from and against any acts, waivers, errors,
delays or omissions, whether caused by Borrower, by any issuer or
correspondent or otherwise with respect to or relating to any
Letter of Credit Accommodation. The provisions of this Section
2.2(e) shall survive the payment of Obligations and the termination
or non-renewal of this Agreement.  

       (f)  Nothing contained herein shall be deemed or construed
to grant Borrower any right or authority to pledge the credit of
Lender in any manner.  Lender shall have no liability of any kind
with respect to any Letter of Credit Accommodation provided by an
issuer other than Lender unless Lender has duly executed and
delivered to such issuer the application or a guarantee or
indemnification in writing with respect to such Letter of Credit
Accommodation.  Borrower shall be bound by any interpretation made
in good faith by Lender, or any other issuer or correspondent under
or in connection with any Letter of Credit Accommodation or any
documents, drafts or acceptances thereunder, notwithstanding that
such interpretation may be inconsistent with any instructions of
Borrower.  Lender shall have the sole and exclusive right and
authority to, and Borrower shall not: (i) at any time an Event of
Default exists or has occurred and is continuing, (A) approve or
resolve any questions of non-compliance of documents, (B) give any
instructions as to acceptance or rejection of any documents or
goods or (C) execute any and all applications for steamship or
airway guaranties, indemnities or delivery orders, and (ii) at all
times, (A) grant any extensions of the maturity of, time of payment
for, or time of presentation of, any drafts, acceptances, or
documents, and (B) agree to any amendments, renewals, extensions,
modifications, changes or cancellations of any of the terms or
conditions of any of the applications, Letter of Credit
Accommodations, or documents, drafts or acceptances thereunder or
any letters of credit included in the Collateral.  Lender may take
such actions either in its own name or in Borrower's name.

       (g)  Any rights, remedies, duties or obligations granted or
undertaken by Borrower to any issuer or correspondent in any
application for any Letter of Credit Accommodation, or any other
agreement in favor of any issuer or correspondent relating to any
Letter of Credit Accommodation, shall be deemed to have been
granted or undertaken by Borrower to Lender.  Any duties or
obligations undertaken by Lender to any issuer or correspondent in
any application for any Letter of Credit Accommodation, or any
other agreement by Lender in favor of any issuer or correspondent
relating to any Letter of Credit Accommodation, shall be deemed to
have been undertaken by Borrower to Lender and to apply in all
respects to Borrower.

  2.3  Term Loan.  Lender is making a Term Loan to Borrower in the
original principal amount equal to the lesser of:  (i) eighty
percent (80%) of the Orderly Liquidation Value of Eligible
Equipment; and (ii) Five Million Nine Hundred Sixty Thousand
Dollars ($5,960,000). The Term Loan is (a) evidenced by a Term
Promissory Note in such original principal amount duly executed and
delivered by Borrower to Lender concurrently herewith; (b) to be

                               11
<PAGE>
repaid, together with interest and other amounts, in accordance
with this Agreement, the Term Promissory Note, and the other
Financing Agreements and (c) secured by all of the Collateral.

  2.4  Availability Reserves.  All Revolving Loans otherwise
available to Borrower pursuant to the lending formulas and subject
to the Maximum Credit and other applicable limits hereunder shall
be subject to Lender's continuing right to establish and revise
Availability Reserves. 

  2.5  Joint and Several Liability; Rights of Contribution.

       (a)  Each Borrower states and acknowledges that: (i)
pursuant to this Agreement, Borrowers desire to utilize  their
borrowing potential on a consolidated basis to the same extent
possible if they were merged into a single corporate entity; (ii)
it has determined that it will benefit specifically and materially
from the advances of credit contemplated by this Agreement; (iii)
it is both a condition precedent to the obligations of Lender
hereunder and a desire of Borrowers that each Borrower execute and
deliver to Lender this Agreement; and (iv) Borrowers have requested
and bargained for the structure and terms of and security for the
advances contemplated by this Agreement.

       (b)  Each Borrower hereby irrevocably and unconditionally: 
(i) agrees that it is jointly and severally liable to Lender for
the full and prompt payment of all the Obligations and the full and
prompt performance of all obligations of any Borrower under this
Agreement or any other Loan Document, notwithstanding anything
herein or in any other Loan Document specifying that a particular
Borrower is responsible for a given payment or performance; (ii)
agrees to fully and promptly perform all of its obligations
hereunder with respect to each advance of credit hereunder as if
such advance had been made directly to it; and (iii) agrees as a
primary obligation to indemnify Lender on demand for and against
any loss incurred by Lender as a result of any of the Obligations
of any of the Borrowers being or becoming void, voidable,
unenforceable or ineffective for any reason whatsoever, whether or
not known to Lender or any Person, the amount of such loss being
the amount which Lender would otherwise have been entitled to
recover from any Borrower.

       (c)  It is the intent of each Borrower that the
indebtedness, obligations and liability hereunder of no one of them
be subject to challenge on any basis.  Accordingly, as of the date
hereof, the liability of each Borrower under this Section 2.5,
together with all of its other liabilities to all Persons as of the
date hereof and as of any other date on which a transfer is deemed
to occur by virtue of this Agreement, calculated in amount
sufficient to pay its probable net liabilities on its existing
Indebtedness as the same become absolute and matured ("Dated
Liabilities") is, and is to be, less than the amount of the
aggregate of a fair valuation of its property as of such
corresponding date ("Dated Assets").  To this end each Borrower
under this Section 2.5 (i) grants to and recognizes in the other
Borrower, ratably, rights of subrogation and contribution in the
amount, if any, by which the Dated Assets of such Borrower, but for
the aggregate of subrogation and contribution in its favor
recognized herein, would exceed the Dated Liabilities of such
Borrower or, as the case may be (ii) acknowledges receipt of and

                              12
<PAGE>
recognizes its right to subrogation and contribution ratably from
the other Borrower in the amount, if any, by which the Dated
Liabilities of such Borrower, but for the aggregate of subrogation
and contribution in its favor recognized herein, would exceed the
Dated Assets of such Borrower under this Section 2.5.  In
recognizing the value of the Dated Assets and the Dated
Liabilities, it is understood that Borrowers will recognize, to at
least the same extent of their aggregate recognition of liabilities
hereunder, their rights to subrogation and contribution hereunder. 
It is a material objective of this Section 2.5 that each Borrower
recognizes rights to subrogation and contribution rather than be
deemed to be insolvent (or in contemplation thereof) by reason of
an arbitrary interpretation of its joint and several obligations
hereunder.

SECTION 3.  INTEREST AND FEES

  3.1  Interest.

       (a)  Borrower shall pay to Lender interest:  (i) on the
outstanding principal amount of the Revolving Loans at a rate of
one and one half percent (1.50%) per annum in excess of the Prime
Rate, and (ii) on the outstanding principal balance of the Term
Loans at a rate of one and three quarters percent (1.75%) per annum
in excess of the Prime Rate, except that Borrower shall pay to
Lender interest, at Lender's option, without notice, at the rate of
three and one half percent (3.50%) per annum in excess of the Prime
Rate with respect to the Receivable Loans, and three and three
quarters percent (3.75%) per annum in excess of the Prime Rate with
respect to the Term Loan:  (x) on the non-contingent Obligations
for the period from and after the date of termination or non-
renewal hereof, or the date of the occurrence of an Event of
Default, and for so long as such Event of Default is continuing as
determined by Lender and until such time as Lender has received
full and final payment of all such Obligations (notwithstanding
entry of any judgment against Borrower) or such Event of Default is
waived by Lender, and (y) on the Revolving Loans at any time
outstanding in excess of the amounts available to Borrower under
Section 2 (whether or not such excess(es), arise or are made with
or without Lender's knowledge or consent and whether made before or
after an Event of Default). All interest accruing hereunder on and
after the occurrence of any of the events referred to in clauses
(x) and (y) above shall be payable on demand.

       (b)  Interest shall be payable by Borrower to Lender
monthly in arrears not later than the first day of each calendar
month and shall be calculated on the basis of a three hundred sixty
(360) day year and actual days elapsed.  The interest rate shall
increase or decrease by an amount equal to each increase or
decrease in the Prime Rate effective on the first day of the month
after any change in such Prime Rate is announced based on the Prime
Rate in effect on the last day of the month in which any such
change occurs. 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
Financing Agreement, or the arising of any contingency whatsoever,
shall entitle Lender to contract for, charge, or receive, in any
event, interest exceeding the maximum rate of interest permitted by
applicable state or federal law in effect from time to time

                                 13
<PAGE>
(hereinafter "Maximum Legal Rate").  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 contracted for,
charged or received in excess of the Maximum Legal Rate ("Excess"),
Borrower acknowledges and stipulates that any such contract,
charge, or receipt shall be the result of an accident and bona fide
error, and that any Excess received by Lender shall be applied,
first, to reduce the principal then unpaid hereunder; second, to
reduce the other 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 Prime Rate and the
Maximum Legal Rate, such a 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 contracting for, charging or receiving of any
interest in excess of the maximum authorized 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.

  3.2  Closing Fee.  Borrower shall pay to Lender as a closing fee
the amount of One Hundred Sixty-Five Thousand Dollars ($165,000),
which shall be fully earned as of and payable on the date hereof.

  3.3  Servicing Fee.  Borrower shall pay to Lender quarterly a
servicing fee in an amount equal to Three Thousand Dollars ($3,000)
in respect of Lender's services for each quarter (or part thereof)
while this Agreement remains in effect and for so long thereafter
as any of the Obligations are outstanding, which fee shall be fully
earned as of and payable in advance on the date hereof and on the
first day of each quarter hereafter. 

  3.4  Commitment Fee.  Borrower shall pay to Lender monthly a
commitment fee at a rate equal to one half of one percent (.50%)
percent per annum calculated upon the amount by which the Maximum
Credit less the outstanding amount of the Term Loan exceeds the
average daily principal balance of the outstanding Revolving Loans
and Letter of Credit Accommodations during the immediately
preceding month (or part thereof) while this Agreement is in effect
and for so long thereafter as any of the Obligations are
outstanding, which fee shall be payable on the first day of each
month in arrears.

for loss or damage to or destruction of any or all of the foregoing.


SECTION 6.  COLLECTION AND ADMINISTRATION

6.1    Borrower's Loan Account.  Lender shall maintain one or more loan 
account(s) on its books in which shall be recorded (a) all Loans, Letter of 
Credit Accommodations and other Obligations and the Collateral, (b) all 
payments made by or on behalf of Borrower and (c) all other appropriate 
debits and credits as provided in this Agreement, including, without 
limitation, fees, charges, costs, expenses and interest.  All entries in 
the loan account(s) shall be made in accordance with Lender's customary 
practices as in effect from time to time.

6.2    Statements.  Lender shall render to Borrower each month a statement 
setting forth the balance in the Borrower's loan account(s) maintained by 
Lender for Borrower pursuant to the provisions of this Agreement, including 
principal, interest, fees, costs and expenses.  Each such statement shall 
be subject to subsequent adjustment by Lender but shall, absent manifest 
errors or omissions, be considered correct and deemed accepted by Borrower 
and conclusively binding upon Borrower as an account stated except to the 
extent that Lender receives a written notice from Borrower of any specific 
exceptions of Borrower thereto within thirty (30) days after the date such 
statement has been mailed by Lender.  Until such time as Lender shall have
rendered to Borrower a written statement as provided above, the balance in 
Borrower's loan account(s) shall be presumptive evidence of the amounts due 
and owing to Lender by Borrower.

6.3    Collection of Accounts.

       (a)  Borrower shall establish and maintain, at its expense, blocked 
accounts or lockboxes and related blocked accounts (in either case, "Blocked
Accounts"), as Lender may specify, with such banks as are acceptable to 
Lender into which Borrower shall promptly deposit and direct its account
debtors to directly remit all payments on Accounts and all payments 
constituting proceeds of Inventory or other Collateral in the identical form

                                  19
<PAGE>
in which such payments are made, whether by cash, check or other manner.  The
banks at which the Blocked Accounts are established shall enter into an 
agreement, in form and substance satisfactory to Lender, providing that all 
items received or deposited in the Blocked Accounts are the property of 
Lender, that the depository bank has no lien upon, or right to setoff 
against, the Blocked Accounts, the items received for deposit therein, or 
the funds from time to time on deposit therein and that the depository bank
will wire, or otherwise transfer, in immediately available funds, on a daily 
basis, all funds received or deposited into the Blocked Accounts to such bank
account of Lender as Lender may from time to time designate for such purpose
("Payment Account").  Borrower agrees that all payments made to such Blocked
Accounts or other funds received and collected by Lender, whether on the 
Accounts or as proceeds of Inventory or other Collateral or otherwise shall
be the property of Lender.

       (b)  For purposes of calculating interest on the Obligations, such 
payments or other funds received will be applied (conditional upon final 
collection) to the Obligations one (1) business day following the date of 
receipt of immediately available funds by Lender in the Payment Account.  
For purposes of calculating the amount of the Revolving Loans available to
Borrower such payments will be applied (conditional upon final collection) to 
the Obligations on the business day of receipt by Lender in the Payment 
Account, if such payments are received within sufficient time (in accordance 
with Lender's usual and customary practices as in effect from time to time) 
to credit Borrower's loan account on such day, and if not, then on the next
business day. 

       (c)  Borrower and all of its affiliates, subsidiaries, employees or 
agents shall, acting as trustee for Lender, receive, as the property of 
Lender, any monies, checks, notes, drafts or any other payment relating to 
and/or proceeds of Accounts or other Collateral which come into their 
possession or under their control and immediately upon receipt thereof, shall 
deposit or cause the same to be deposited in the Blocked Accounts, or remit 
the same or cause the same to be remitted, in kind, to Lender.  In no event 
shall the same be commingled with Borrower's own funds.  Borrower agrees to 
reimburse Lender on demand for any amounts owed or paid to any bank at which a 
Blocked Account is established or any other bank or person involved in the 
transfer of funds to or from the Blocked Accounts arising out of Lender's 
payments to or indemnification of such bank or person in connection with 
such Blocked Accounts.  The obligation of Borrower to reimburse Lender for 
such amounts pursuant to this Section 6.3 shall survive the termination or 
non-renewal of this Agreement.

6.4    Payments.  All Obligations shall be payable to the Payment Account as
provided in Section 6.3 or such other place as Lender may designate from time 
to time.  Lender may apply payments received or collected from Borrower or 
for the account of Borrower (including, without limitation, the monetary 
proceeds of collections or of realization upon any Collateral) to such of 
the Obligations, whether or not then due, in such order and manner as
Lender determines. At Lender's option, all principal, interest, fees, costs,
expenses and other charges provided for in this Agreement or the other 
Financing Agreements may be charged directly to the loan account(s) of 
Borrower.  Borrower shall make all payments  to Lender on the Obligations 
free and clear of, and without deduction or withholding for or on account 
of, any setoff, counterclaim, defense, duties, taxes, levies, imposts, 

                                 20
<PAGE>
fees, deductions, withholding, restrictions or conditions of any kind.  If 
after receipt of any payment of, or proceeds of Collateral applied to the 
payment of, any of the Obligations, Lender is required to surrender or
return such payment or proceeds to any Person for any reason, then the 
Obligations intended to be satisfied by such payment or proceeds shall be 
reinstated and continue and this Agreement shall continue in full force 
and effect as if such payment or proceeds had not been received by Lender.  
Borrower shall be liable to pay to Lender, and does hereby indemnify and 
hold Lender harmless for the amount of any payments or proceeds surrendered 
or returned by Lender pursuant to this Section 6.4.  This Section 6.4 shall 
remain effective notwithstanding any contrary action which may be taken by 
Lender in reliance upon such payment or proceeds.  This Section 6.4 shall 
survive the payment of the Obligations and the termination or non-renewal of
this Agreement.

6.5    Authorization to Make Loans.  Lender is authorized to make the Loans 
and provide the Letter of Credit Accommodations based upon telephonic or 
other instructions received from anyone purporting to be an officer of 
Borrower or other authorized person or, at the discretion of Lender, if 
such Loans are necessary to satisfy any Obligations.  All requests for Loans
or Letter of Credit Accommodations hereunder shall specify the date on which 
the requested advance is to be made or Letter of Credit Accommodations 
established (which day shall be a business day) and the amount of the 
requested Loan.  Requests received after 11:00 a.m. Central Time on any day 
shall be deemed to have been made as of the opening of business on the 
immediately following business day.  All Loans and Letter of Credit 
Accommodations under this Agreement shall be conclusively presumed to have 
been made to, and at the request of and for the benefit of, Borrower when 
deposited to the credit of Borrower or otherwise disbursed or established 
in accordance with the instructions of Borrower or in accordance with
the terms and conditions of this Agreement.

6.6    Use of Proceeds.  Borrower shall use the initial proceeds of the Loans
provided by Lender to Borrower hereunder only for:  (a) payments to each of 
the persons listed in the disbursement direction letter furnished by Borrower
to Lender on or about the date hereof and (b) costs, expenses and fees in 
connection with the preparation, negotiation, execution and delivery of this
Agreement and the other Financing Agreements.  All other Loans made or Letter
of Credit Accommodations provided by Lender to Borrower pursuant to the 
provisions hereof shall be used by Borrower only for general operating, 
working capital and other proper corporate purposes of Borrower not otherwise
prohibited by the terms hereof.  None of the proceeds will be used, directly
or indirectly, for the purpose of purchasing or carrying any margin security or
for the purposes of reducing or retiring any indebtedness which was originally 
incurred to purchase or carry any margin security or for any other purpose 
which might cause any of the Loans to be considered a "purpose credit" within
the meaning of Regulation G of the Board of Governors of the Federal Reserve 
System, as amended.

SECTION 7.  COLLATERAL REPORTING AND COVENANTS

     7.1    Collateral Reporting.  Borrower shall provide Lender with the

accounting service, contractor, shipper or other agent, Borrower hereby
irrevocably authorizes such service, contractor, shipper or agent to deliver
such records, reports, and related documents to Lender and to follow

Event of Default exists or has occurred and is continuing.

any account debtor, or any material disputes with account debtors, or any 
settlement, adjustment or compromise thereof, (ii) all material adverse
information relating to the financial condition of any account debtor that 
the Borrower becomes aware of, and (iii) any event or circumstance which, 
to Borrower's knowledge would cause Lender to consider any then existing 
Accounts as no longer constituting Eligible Accounts.  No credit, discount, 
allowance or extension or agreement for any of the foregoing shall be granted
to any account debtor without Lender's consent, except in the ordinary course
of Borrower's business in accordance with practices and policies previously 
disclosed in writing to Lender. So long as no Event of Default exists or 
has occurred and is continuing, Borrower shall settle, adjust or compromise 
any claim, offset, counterclaim or dispute with any account debtor.  At any
time that an Event of Default exists or has occurred and is continuing, 
Lender shall, at its option, have the exclusive right to settle, adjust or 
compromise any claim, offset, counterclaim or dispute with account debtors 
or grant any credits, discounts or allowances.

       (b)  With respect to each Account:  (i) the amounts shown on any 
invoice delivered to Lender or schedule thereof delivered to Lender shall be
true and complete, (ii) no payments shall be made thereon except payments

business in accordance with practices and policies previously disclosed to 
Lender, (iv) there shall be no setoffs, deductions, contras, defenses, 
counterclaims or disputes existing or asserted with respect thereto except

<PAGE>
(v) none of the transactions giving rise thereto will violate any applicable
State or Federal laws or regulations, all documentation relating thereto 
will be legally sufficient under such laws and regulations and all such
documentation will be legally enforceable in accordance with its terms.

       (c)  Lender shall have the right at any time or times, in Lender's name 
or in the name of a nominee of Lender, to verify the validity, amount or any 
other matter relating to any Account or other Collateral, by mail, telephone,
facsimile transmission or otherwise.

       (d)  Borrower shall deliver or cause to be delivered to Lender, with
appropriate endorsement and assignment, with full recourse to Borrower, all 
chattel paper and instruments which Borrower now owns or may at any time 
acquire immediately upon Borrower's receipt thereof, except as Lender may 
otherwise agree.

       (e)  Lender may, at any time or times that an Event of Default exists 
or has occurred and is continuing, (i) notify any or all account debtors 
that the Accounts have been assigned to Lender and that Lender has a security 
interest therein and Lender may direct any or all accounts debtors to make 
payment of Accounts directly to Lender, (ii) extend the time of payment of, 
compromise, settle or adjust for cash, credit, return of merchandise or 
otherwise, and upon any terms or conditions, any and all Accounts or other 
obligations included in the Collateral and thereby discharge or release the 
account debtor or any other party or parties in any way liable for payment 
thereof without affecting any of the Obligations, (iii) demand, collect or 
enforce payment of any Accounts or such other obligations, but without any 
duty to do so, and Lender shall not be liable for its failure to collect
or enforce the payment thereof nor for the negligence of its agents or 
attorneys with respect thereto and (iv) take whatever other action Lender 
may deem necessary or desirable for the protection of its interests.  At 
any time that an Event of Default exists or has occurred and is continuing, 
at Lender's request, all invoices and statements sent to any account debtor 
shall state that the Accounts and such other obligations have been assigned 
to Lender and are payable directly and only to Lender and Borrower shall 
deliver to Lender such originals of documents evidencing the sale and 
delivery of goods or the performance of services giving rise to any Accounts
as Lender may require. 

  7.3  Inventory Covenants.  With respect to the Inventory owned by Borrower:

reasonably satisfactory to Lender concerning such physical count; (c) 
Borrower shall not remove any Inventory from the locations set forth or
permitted herein, without the prior written consent of Lender, except for sales

consumption of such Inventory in the ordinary maintenance of Borrower's 
Equipment constituting motor vehicles, and except to move Inventory directly
from one location set forth or permitted herein to another such location; (d)

                                  23

all rules, regulations and orders related thereto); (e) Borrower assumes all
responsibility and liability arising from or relating to the production, use,

such location and except for the movement or location of motor vehicles or 
rolloff boxes used by or for the benefit of Borrower in the ordinary course 
of business; (f) the Equipment is now and shall remain personal property
and Borrower shall not permit any of the Equipment to be or become a part of
or affixed to real property; (g) Borrower assumes all responsibility and 
liability arising from the use of the Equipment; and (h) Borrower shall 
provide Lender, within one hundred twenty (120) days after the initial

motor vehicles constituting part of the Equipment, noting Lender's lien on 
the face of such certificates of title and satisfying such other conditions 
as may be required for perfection of Lender's security interests in such 
Equipment.

  7.5  Power of Attorney.  Borrower hereby irrevocably designates and appoints 
Lender (and all persons designated by Lender) as Borrower's true and lawful 
attorney-in-fact, and authorizes Lender, in Borrower's or Lender's name, to:

SECTION 8.  REPRESENTATIONS AND WARRANTIES

  Borrower hereby represents and warrants to Lender the following (which shall 
survive the execution and delivery of this Agreement), the truth and accuracy 
of which are a continuing condition of the making of Loans and providing 
Letter of Credit Accommodations by Lender to Borrower:

  8.1  Corporate Existence, Power and Authority; Subsidiaries.  Borrower is a 
corporation duly organized and in good standing under the laws of its state 
of incorporation and is duly qualified as a foreign corporation and in good 
standing in all states or other jurisdictions where the nature and extent of
the business transacted by it or the ownership of assets makes such
qualification necessary, except for those jurisdictions in which the failure 
to so qualify would not have a material adverse effect on Borrower's 
financial condition, results of operation or business, on a consolidated 
basis, or the rights of Lender in or to any of the Collateral.  The 
execution, delivery and performance of this Agreement, the other Financing 
Agreements and the transactions contemplated hereunder and thereunder are all 
within Borrower's corporate powers, have been duly authorized and are not

compliance with any of the Environmental Laws and shall regularly report
to Lender on such response.

     (c)    Borrower shall give both oral and written notice to Lender as soon

business, operations or assets on a consolidated basis.

     (d)    Without limiting the generality of the foregoing, whenever Lender
reasonably determines that there is a material non-compliance, or any 
condition which requires any action by or on behalf of Borrower in order to 
avoid any material non-compliance, with any Environmental Law, of which non-
compliance would result in a material adverse effect on the Borrower on a 
consolidated basis, Borrower shall, at Lender's request and Borrower's 
expense: (i) cause an independent environmental engineer acceptable to Lender 
to conduct such tests of the site where Borrower's non-compliance or alleged
non-compliance with such Environmental Laws has occurred as to such non-
compliance and prepare and deliver to Lender a report as to such non-
compliance setting forth the results of such tests, a proposed plan for 
responding to any environmental problems described therein, and an estimate 
of the costs thereof and (ii) provide to Lender a supplemental report of such 
engineer whenever the scope of such non-compliance, or Borrower's response 
thereto or the estimated costs thereof, shall change in any material respect.

     (e)  Borrower shall indemnify and hold harmless Lender, its directors, 
officers, employees, agents, invitees, representatives, successors and 
assigns, from and against any and all losses, claims, damages, liabilities,

or indirectly arising out of or attributable to Borrower's use, generation,
manufacture, reproduction, storage, release, threatened release, spill, 
discharge, disposal or presence of a Hazardous Material, including the costs 
of any required or necessary repair, cleanup or other remedial work with 
respect to any property of Borrower and the preparation and implementation

all taxes, assessments, contributions and governmental charges upon or 
against it or its properties or assets, except for taxes the validity of

pursued and available to Borrower and with respect to which adequate reserves 
have been set aside on its books.  Borrower shall be liable for any tax or 
penalties imposed on Lender as a result of the financing arrangements 
provided for herein and Borrower agrees to indemnify and hold Lender harmless 

                                  30
<PAGE>
with respect to the foregoing, and to repay to Lender on demand the amount 
thereof, and until paid by Borrower such amount shall be added and deemed 
part of the Loans, provided, that, nothing contained herein shall be 
construed to require Borrower to pay any income or franchise taxes 
attributable to the income of Lender from any amounts charged or paid 
hereunder to Lender.  The foregoing indemnity shall survive the payment of 
the Obligations and the termination or non-renewal of this Agreement.

     9.5  Insurance.  Borrower shall, at all times, maintain with financially 
sound and reputable insurers insurance with respect to the Collateral against
loss or damage and all other insurance of the kinds and in the amounts

reputation engaged in the same or similar businesses and similarly situated,
except that Borrower self insures all loss due to collision on its motor 
vehicles.  Said policies of insurance shall be satisfactory to Lender as to 
form, amount and insurer.  Borrower shall furnish certificates, policies or 
endorsements to Lender as Lender shall require as proof of such insurance, 
and, if Borrower fails to do so, Lender is authorized, but not required, to 
obtain such insurance at the expense of Borrower.  All policies shall provide 
for at least thirty (30) days prior written notice to Lender of any 
cancellation or reduction of coverage and that Lender may act as attorney 
for Borrower in obtaining, and at any time an Event of Default exists or 
has occurred and is continuing, adjusting, settling, amending and canceling 
such insurance. Borrower shall cause Lender to be named as a loss payee, as 
its interest may appear, and an additional insured (but without any liability 
for any premiums) under such insurance policies and Borrower shall obtain 
non-contributory lender's loss payable endorsements to all insurance policies
in form and substance satisfactory to Lender.  Such lender's loss payable 
endorsements shall specify that the proceeds of such insurance shall be 
payable to Lender as its interests may appear and further specify that Lender 
shall be paid regardless of any act or omission by Borrower or any of its 
affiliates.  At its option, prior to the occurrence and continuance of an
Event of Default, any insurance proceeds received by Lender at any time shall 
be applied to the cost of repairs or replacement of Collateral.  After the 
occurrence and continuance of an Event of Default, any insurance proceeds 
received by the Lender at any time shall be applied to payment of the 
Obligations, whether or not then due, in any order and in such manner as 
Lender may determine or hold such proceeds as cash collateral for the 
Obligations.

behalf of Borrower and to disclose to Lender such information as they may

ETS) file consolidated income tax returns and payroll tax returns and pay 
such, if any, on a consolidated basis, and that such filings and payment of 
taxes in connection therewith shall not be considered a loan, investment,
guarantee or capital contribution for purposes of this Section 9.10.

transaction for the purchase, sale or exchange of property or the rendering 
of any service to or by any affiliate, except in the ordinary course of and 
pursuant to the reasonable requirements of Borrower's business and upon 
fair and reasonable terms no less favorable to the Borrower than Borrower
would obtain in a comparable arm's length transaction with an unaffiliated 
person; provided, however, that nothing in this Section 9.12 shall limit or 
restrict transactions between one Borrower and another Borrower so long as 
such transactions do not exceed Five Thousand Dollars ($5,000) in the

thereto, including any amendments, supplements or consents which may 
hereafter be contemplated (whether or not executed) or entered into in

financing statement filing taxes and fees, documentary taxes, intangibles

to Lender in connection with any of the foregoing.

  9.15 After Acquired Real Property.  If Borrower hereafter acquires any 
title to the Real Property, fixtures or any other property that is of the 
kind or nature described in the Mortgages and such Real Property, fixtures 
or other property at any one location has a fair market value in an amount 
equal to or greater than Fifty Thousand Dollars ($50,000) (or if an Event 
of Default has occurred and is continuing, then regardless of the fair 
market value of such assets), without limiting any other rights of Lender, 
or duties or obligations of Borrower, upon Lender's request, Borrower shall 
execute and deliver to Lender a mortgage, deed of trust or deed to secure 
debt, as Lender may determine, in form and substance substantially similar 
to the Mortgages and as to any provisions relating to specific state laws 
satisfactory to Lender and in form appropriate for recording in the real 
estate records of the jurisdiction in which such Real Property or other 
property is located granting to Lender a first and only lien and mortgage 
on and security interest in such Real Property, fixtures or other property 
(except as Borrower would otherwise be permitted to incur hereunder or 
under the Mortgages or as otherwise consented to in writing by Lender) and 
such other agreements, documents and instruments as Lender may require in
connection therewith.

to time, Borrower shall, at its expense, duly execute and deliver, or cause 
to be duly executed and delivered, such further agreements, documents and

or proper to evidence, perfect, maintain and enforce the security interests 
and the priority thereof in the Collateral and to otherwise effectuate the
provisions or purposes of this Agreement or any of the other Financing 
Agreements.  Lender may at any time and from time to time request a 
certificate from an officer of Borrower representing that all conditions 
precedent to the making of Loans and providing Letter of Credit
Accommodations contained herein are satisfied.  In the event of such request 
by Lender, Lender may, at its option, cease to make any further Loans or 
provide any further Letter of Credit Accommodations until Lender has 
received such certificate and, in addition, Lender has determined that such 
conditions are satisfied.  Where permitted by law, Borrower hereby authorizes
Lender to execute and file one or more UCC financing statements signed only 
by Lender.

       (a)  At any time an Event of Default exists or has occurred and is 
continuing, Lender shall have all rights and remedies provided in this Agree-
ment, the other Financing Agreements, the Uniform Commercial Code and other 
applicable law, all of which rights and remedies may be exercised without 
notice to or consent by Borrower or any Obligor, except as such notice or 
consent is expressly provided for hereunder or required by applicable law. All
rights, remedies and powers granted to Lender hereunder, under any of the 
other Financing Agreements, the Uniform Commercial Code or other applicable 
law, are cumulative, not exclusive and enforceable, in Lender's discretion, 
alternatively, successively, or concurrently on any one or more occasions, 
and shall include, without limitation, the right to apply to a court of
equity for an injunction to restrain a breach or threatened breach by 
Borrower of this Agreement or any of the other Financing Agreements.  Lender 
may, at any time or times, proceed directly against Borrower or any Obligor 
to collect the Obligations without prior recourse to the Collateral.


                                 39
<PAGE>
       (b)  Without limiting the foregoing, at any time an Event of Default 
exists or has occurred and is continuing, Lender may, in its discretion and 
without limitation, (i) accelerate the payment of all Obligations and demand
immediate payment thereof to Lender (provided, that, upon the occurrence of 
any Event of Default described in Sections 10.1(e) and 10.1(f), all 
Obligations shall automatically become immediately due and payable), (ii) 
with or without judicial process or the aid or assistance of others, enter 
upon any premises on or in which any of the Collateral may be located and 
take possession of the Collateral or complete processing, manufacturing and 
repair of all or any portion of the Collateral, (iii) require Borrower, at
Borrower's expense, to assemble and make available to Lender any part or all 
of the Collateral at any place and time designated by Lender, (iv) collect, 
foreclose, receive, appropriate, setoff and realize upon any and all 
Collateral, (v) remove any or all of the Collateral from any premises on or 
in which the same may be located for the purpose of effecting the sale,
foreclosure or other disposition thereof or for any other purpose, (vi) sell, 
lease, transfer, assign, deliver or otherwise dispose of any and all 
Collateral (including, without limitation, entering into contracts with 
respect thereto, public or private sales at any exchange, broker's board, 
at any office of Lender or elsewhere) at such prices or terms as Lender may 
deem reasonable, for cash, upon credit or for future delivery, with the 
Lender having the right to purchase the whole or any part of the Collateral 
at any such public sale, all of the foregoing being free from any right or
equity of redemption of Borrower, which right or equity of redemption is 
hereby expressly waived and released by Borrower and/or (vii) terminate 
this Agreement.  If any of the Collateral is sold or leased by Lender upon 
credit terms or for future delivery, the Obligations shall not be reduced 
as a result thereof until payment therefor is finally collected by Lender.  
If notice of disposition of Collateral is required by law, five (5) days 
prior notice by Lender to Borrower designating the time and place of any 
public sale or the time after which any private sale or other intended 
disposition of Collateral is to be made, shall be deemed to be reasonable 
notice thereof and Borrower waives any other notice.  In the event Lender 
institutes an action to recover any Collateral or seeks recovery of any 
Collateral by way of prejudgment remedy, Borrower waives the posting of 
any bond which might otherwise be required.

       (c)  Lender may apply the cash proceeds of Collateral actually 
received by Lender from any sale, lease, foreclosure or other disposition 
of the Collateral to payment of the Obligations, in whole or in part and 
in such order as Lender may elect, whether or not then due. Borrower shall 
remain liable to Lender for the payment of any deficiency with interest at 
the highest rate provided for herein and all costs and expenses of collection 
or enforcement, including attorneys' fees and legal expenses.

       (d)  Without limiting the foregoing, upon the occurrence of an Event 
of Default or an event which with notice or passage of time or both would 
constitute an Event of Default, Lender may, at its option, without notice, 
(i) cease making Loans or arranging for Letter of Credit Accommodations or 
reduce the lending formulas or amounts of Revolving Loans and Letter of 
Credit Accommodations available to Borrower and/or (ii) terminate any 
provision of this Agreement providing for any future Loans or Letter of 
Credit Accommodations to be made by Lender to Borrower and/or (iii) 
terminate this Agreement.

effect to principles of conflicts of law).

       (b)  Borrower and Lender irrevocably consent and submit to the non-
exclusive jurisdiction of the State of Texas and the United States District 
Court for the Northern District of Texas and waive any objection based on 
venue or forum non conveniens with respect to any action instituted therein 
arising under this Agreement or any of the other Financing Agreements
or in any way connected with or related or incidental to the dealings of the
parties hereto in respect of this Agreement or any of the other Financing 
Agreements or the transactions related hereto or thereto, in each case 
whether now existing or hereafter arising, and whether in contract, tort, 
equity or otherwise, and agree that any dispute with respect to any such 
matters shall be heard only in the courts described above (except that Lender
shall have the right to bring any action or proceeding against Borrower or 
its property in the courts of any other jurisdiction which Lender deems 
necessary or appropriate in order to realize on the Collateral or to 
otherwise enforce its rights against Borrower or its property).

       (c)  Borrower hereby waives personal service of any and all process 
upon it and consents that all such service of process may be made by 
certified mail (return receipt requested) directed to its address set forth 
on the signature pages hereof and service so made shall be deemed to be 
completed five (5) days after the same shall have been so deposited in the
U. S. mails, or, at Lender's option, by service upon Borrower in any other 
manner provided under the rules of any such courts.  Within thirty (30) 
days after such service, Borrower shall appear in answer to such process, 
failing which Borrower shall be deemed in default and judgment may
be entered by Lender against Borrower for the amount of the claim and other 
relief requested.

       (d)  BORROWER AND LENDER EACH HEREBY WAIVES ANY RIGHT
TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION 
ARISING UNDER THIS AGREEMENT OR ANY OF THE OTHER FINANCING
AGREEMENTS OR IN ANY WAY CONNECTED WITH OR RELATED OR
INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO IN RESPECT OF
THIS AGREEMENT OR ANY OF THE OTHER FINANCING AGREEMENTS OR THE
TRANSACTIONS RELATED HERETO OR THERETO IN EACH CASE WHETHER
NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT,
TORT, EQUITY OR OTHERWISE.  BORROWER AND LENDER EACH HEREBY
AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE

                                41
<PAGE>
OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND
THAT BORROWER OR LENDER MAY FILE AN ORIGINAL COUNTERPART OF A
COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF
THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT
TO TRIAL BY JURY.

       (e)  LENDER SHALL NOT HAVE ANY LIABILITY TO BORROWER
(WHETHER IN TORT, CONTRACT, EQUITY OR OTHERWISE) FOR LOSSES
SUFFERED BY BORROWER IN CONNECTION WITH, ARISING OUT OF, OR IN
ANY WAY RELATED TO THE TRANSACTIONS OR RELATIONSHIPS
CONTEMPLATED BY THIS AGREEMENT, OR ANY ACT, OMISSION OR EVENT
OCCURRING IN CONNECTION HEREWITH, UNLESS IT IS DETERMINED BY A
FINAL AND NON-APPEALABLE JUDGMENT OR COURT ORDER BINDING ON
LENDER, THAT THE LOSSES WERE THE RESULT OF ACTS OR OMISSIONS
CONSTITUTING GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.  IN ANY
SUCH LITIGATION, LENDER SHALL BE ENTITLED TO THE BENEFIT OF THE
REBUTTABLE PRESUMPTION THAT IT ACTED IN GOOD FAITH AND WITH THE
EXERCISE OF ORDINARY CARE IN THE PERFORMANCE BY IT OF THE TERMS
OF THIS AGREEMENT.

  11.2 Waiver of Notices.  Borrower hereby expressly waives demand, present-

instruments and commercial paper, included in or evidencing any of
the Obligations or the Collateral, and any and all other demands and 
notices of any kind or nature whatsoever with respect to the Obligations, 
the Collateral and this Agreement, except such as are expressly provided 
for herein. No notice to or demand on Borrower which Lender may elect to 
give shall entitle Borrower to any other or further notice or demand in 
the same, similar or other circumstances.

  11.3 Amendments and Waivers.  Neither this Agreement nor any provision 
hereof shall be amended, modified, waived or discharged orally or by course 
of conduct, but only by a written agreement signed by an authorized officer 
of Lender.  Lender shall not, by any act, delay, omission or otherwise be 
deemed to have expressly or impliedly waived any of its rights, powers 
and/or remedies unless such waiver shall be in writing and signed by an 
authorized officer of Lender.  Any such waiver shall be enforceable only to 
the extent specifically set forth therein.  A waiver by Lender of any right,
power and/or remedy on any one occasion shall not be construed as a bar to 
or waiver of any such right, power and/or remedy which Lender would
otherwise have on any future occasion, whether similar in kind or otherwise.

  11.4 Waiver of Counterclaims.  Borrower waives all rights to interpose any 
claims, deductions, setoffs or counterclaims of any nature (other then 
compulsory counterclaims) in any action or proceeding with respect to this 
Agreement, the Obligations, the Collateral or any matter arising therefrom 
or relating hereto or thereto.

  11.5 INDEMNIFICATION.  BORROWER SHALL INDEMNIFY AND HOLD
LENDER, AND ITS DIRECTORS, AGENTS, EMPLOYEES AND COUNSEL,
HARMLESS FROM AND AGAINST ANY AND ALL LOSSES, CLAIMS, DAMAGES,
LIABILITIES, COSTS OR EXPENSES IMPOSED ON, INCURRED BY OR ASSERTED

OF LENDER OR ITS AGENTS OR AFFILIATES.  TO THE EXTENT THAT THE
UNDERTAKING TO INDEMNIFY, PAY AND HOLD HARMLESS SET FORTH IN
THIS SECTION 11.5 MAY BE UNENFORCEABLE BECAUSE IT VIOLATES ANY
LAW OR PUBLIC POLICY, BORROWER SHALL PAY THE MAXIMUM PORTION
WHICH IT IS PERMITTED TO PAY UNDER APPLICABLE LAW TO LENDER IN
SATISFACTION OF INDEMNIFIED MATTERS UNDER THIS SECTION.  THE
FOREGOING INDEMNITY SHALL SURVIVE THE PAYMENT OF THE
OBLIGATIONS AND THE TERMINATION OR NON-RENEWAL OF THIS
AGREEMENT.


SECTION 12.  TERM OF AGREEMENT; MISCELLANEOUS

  12.1 Term.

       (a)  This Agreement and the other Financing Agreements shall become 
effective as of the date set forth on the first page hereof and shall 
continue in full force and effect for a term ending on the date two (2) 
years from the date hereof (the "Renewal Date"), and from year to year 
thereafter, unless sooner terminated pursuant to the terms hereof; provided, 
that, Lender may, at its option, extend the Renewal Date to the date one 
(1) year from the Renewal Date by giving Borrower notice at least sixty 
(60) days prior to the second anniversary of this Agreement.  Lender or 
Borrower (subject to Lender's right to extend the Renewal Date as provided 
above) may terminate this Agreement and the other Financing Agreements 
effective on the Renewal Date or on the anniversary of the Renewal Date in 
any year by giving to the other party at least sixty (60) days prior 
written notice; provided, that, this Agreement and all other Financing 
Agreements must be terminated simultaneously.  Upon the effective date of
termination or non-renewal of the Financing Agreements, Borrower shall pay to 
Lender, in full, all outstanding and unpaid Obligations and shall furnish 

                                  43
<PAGE>
cash collateral to Lender in such amounts as Lender determines are reasonably 
necessary to secure Lender from loss, cost, damage or expense, including 
reasonable attorneys' fees and legal expenses, in connection with any 
contingent Obligations, including issued and outstanding Letter of Credit 
Accommodations and checks or other payments provisionally credited to the 
Obligations and/or as to which Lender has not yet received final and 
indefeasible payment.  Such cash collateral shall be remitted by wire 
transfer in Federal funds to such bank account of Lender, as Lender may, 
in its discretion, designate in writing to Borrower for such purpose.  
Interest shall be due until and including the next business day, if the 
amounts so paid by Borrower to the bank account designated by Lender are 
received in such bank account later than 12:00 noon, Dallas, Texas time.

       (b)  No termination of this Agreement or the other Financing Agreements 
shall relieve or discharge Borrower of its respective duties, obligations and 
covenants under this Agreement or the other Financing Agreements until all 
Obligations have been fully and finally discharged and paid, and Lender's 
continuing security interest in the Collateral and the rights and remedies 
of Lender hereunder, under the other Financing Agreements and applicable law,
shall remain in effect until all such Obligations have been fully and finally 
discharged and paid.

       (c)  If for any reason this Agreement is terminated prior to the end of 
the then current term or renewal term of this Agreement, in view of the 
impracticality and extreme difficulty of ascertaining actual damages and by 
mutual agreement of the parties as to a reasonable calculation of Lender's 
lost profits as a result thereof, Borrower agrees to pay to Lender, upon 
the effective date of such termination, an early termination fee in the 
amount set forth below if such termination is effective in the period 
indicated: 

                   Amount                         Period
                   ______                        __________
       (i)    Four Percent (4%) of       First twelve (12) month period
              Maximum Credit             following the Effective Date

       (ii)   Two Percent (2%) of        Second twelve (12) month period
              Maximum Credit             following the Effective Date

       (iii)  One Percent (1%) of        Third twelve (12) month period
              Maximum                    following the Effective Date
                                         if this Agreement is renewed
                                         pursuant to Section 12.1(a).

Such early termination fee shall be presumed to be the amount of damages 
sustained by Lender as a result of such early termination and Borrower 
agrees that it is reasonable under the circumstances currently existing.  
The early termination fee provided for in this Section 12.1 shall be 
deemed included in the Obligations.

                                 44
