2.   LENDING AGREEMENT.  Subject to the terms and conditions of
this Agreement and the Loan Documents, and in reliance upon the
representations and warranties contained herein and therein:

     2.1  Revolving Loan. The Bank agrees to renew, extend and
increase the Revolving Loan established under the Existing Loan
Agreement and to make Revolving Advances thereunder to the Borrower
from time to time during the Commitment Period in an aggregate
amount at any time outstanding not to exceed the Revolving
Commitment. The Borrower may request Revolving Advances from time
to time under the Revolving Loan in accordance with the provisions
of Subsection 2.3 hereof, and may prepay and re-borrow on a
revolving basis; provided, however, that the aggregate principal
amount of all Revolving Advances at any time outstanding under the
Revolving Loan shall not exceed the lesser of (i) the Revolving
Commitment as in effect on such date, and (ii) the Borrowing Base
as in effect on such date. The Borrower acknowledges and agrees
that the principal balance outstanding under the Revolving Loan at
the close of business on the Effective Date was $649,979.25 and
that Borrower has no defense, counterclaim or offset with respect
to the Existing Loan Agreement or the Revolving Loan.

     2.2  Use of Proceeds. The proceeds of each Revolving Advance
will be used by the Borrower for working capital purposes.

     2.3  Borrowing Procedures.  The Borrower may request a
Revolving Advance on any Business Day during the Commitment Period.
The Borrower shall make each request by giving the Bank written
notice (which may be sent via telefacsimile) in the form of a
properly completed and executed Disbursement Request stating the
amount of the requested Revolving Advance (which amount shall be at
least $5,000.00); provided, however, that the Borrower may give
oral notice by telephone if confirmed by a written notice (which
may be sent via telefacsimile) in the form of a properly completed
and executed Disbursement Request within three (3) Business Days
thereafter. Subject to the Borrower's satisfaction of all other
conditions precedent as set forth in Subsection 4.3 hereof, each
Revolving Advance will be made on the same Business Day on which
the Bank receives the Borrower's Disbursement Request, if the
Disbursement Request is received by 1:00 p.m., or on the following
Business Day, if it is received after 1:00 p.m. The Bank will make
each Revolving Advance by crediting the general operating account
maintained by the Borrower with the Bank.

     2.4  Revolving Note. The Revolving Advances from time to time
outstanding under the Revolving Loan (including amounts advanced
under the Existing Loan Agreement) will be evidenced by the
Revolving Note, which shall be made and delivered by the Borrower
at or prior to the Effective Date. Notwithstanding the principal
amount stated on the face of the Revolving Note, the actual
principal due from the Borrower on account of the Revolving Note
will be the sum of all Revolving Advances from time to time made by
the Bank (including amounts advanced under the Existing Loan
Agreement), less all principal payments actually received by the
Bank in collected funds. Each Revolving Advance and each principal
payment under the Revolving Loan will be recorded by the Bank in
its books and records, and the unpaid principal balance so recorded
will be presumptive evidence of the principal amount owing under
the Revolving Note.

     2.5  Interest.

          2.5.1     Rate. The unpaid principal amount of the
     Revolving Advances from time to time outstanding under the
     Revolving Note will bear interest at a fluctuating rate per
     annum equal to the Prime Rate, plus the Applicable Margin;
     provided, however, that, upon the occurrence of any Event of
     Default and until cured to the satisfaction of the Bank, the
     unpaid principal amount of all Revolving Advances from time to
     time outstanding under the Revolving Note will bear interest
     at a fluctuating rate per annum equal to the Prime Rate (but
     not less than the Prime Rate in effect on the date of the
     occurrence of the Event of Default), plus five (5) percentage
     points. The interest rate payable under the Revolving Note
     will be adjusted as of the opening of business on the day of
     each change in the Prime Rate and as of the first day of the
     fiscal quarter following any change in the Applicable Margin.

          2.5.2     Payment.  Interest shall be due and payable
     monthly in arrears on the last day of each calendar month
     commencing November 30, 1996, and on the Maturity Date.

          2.5.3     Computation of Interest.  Interest on the
     Revolving Advances outstanding under the Revolving Note shall
     be computed on the basis of a year consisting of 360 days and
     for the actual number of days elapsed.

     2.6  Non-Use Fee. The Borrower will pay the Bank a "Non-Use
Fee" calculated at the rate of one half of one percent (0.5%) per
annum on the average daily unborrowed amount of the Revolving
Commitment, payable monthly in arrears on the first day of each
month beginning on December 1, 1996, with final payment being due
and payable on the Maturity Date. The calculation of the "Non-Use
Fee" will be based upon a year consisting of 360 days and for the
actual number of days elapsed.

     2.7  Principal Payments.

          2.7.1     Maturity.  The entire outstanding principal
     balance of the Revolving Note, together with all unpaid
     interest accrued thereon, shall be due and payable in full on
     the Maturity Date.

          2.7.2     Clean-Down Periods. At least once during each
     fiscal year of the Borrower, the Borrower shall designate a
     period of thirty (30) consecutive calendar days as a "Clean-
     Down Period." During each Clean-Down Period: (a) the aggregate
     outstanding Revolving Advances shall not exceed the sum of
     $850,000.00; and (b) the Borrower shall not request, and the
     Bank shall not be obligated to make, any new Revolving
     Advances if the making of such Revolving Advances would cause
     the aggregate outstanding Revolving Advances to exceed
     $850,000.00.

          2.7.3     Mandatory Prepayments. If the principal balance
     of the Revolving Advances outstanding under the Revolving Note
     at any time exceeds the Borrowing Base then in effect, the
     Borrower shall make an immediate mandatory prepayment of
     principal on the Revolving Note in an amount equal to the
     excess.

     2.8  Optional Prepayment. The Borrower may, from time to time,
prepay the outstanding principal amount of the Revolving Note, in
whole or in part, without premium or penalty.

     2.9  Making of Payments.  All payments, including prepayments,
of principal or interest on the Revolving Note shall be made to the
Bank at its principal office in Oklahoma City, Oklahoma, on or
before 2:00 p.m., on the date due in immediately available funds.
Whenever a payment is due on a day other than a Business Day, the
due date shall be extended to the next succeeding Business Day and
interest (if any) shall accrue during such extension.

     2.10 Maximum Lawful Interest Rate.  It is not the intention of
the Bank or the Borrower to violate the Laws of any applicable
jurisdiction relating to usury or other restrictions on the maximum
lawful interest rate. The Loan Documents and all other agreements
between the Borrower and the Bank, whether now existing or
hereafter arising and whether written or oral, are hereby limited
so that in no event shall the interest paid or agreed to be paid to
the Bank for the use, forbearance or detention of money loaned, or
for the payment or performance of any covenant or obligation
contained herein or in any other Loan Document, exceed the maximum
amount permissible under applicable law. If from any circumstances
whatsoever fulfillment of any provision hereof or of any other Loan
Document, at the time the performance of such provision shall be
due, shall involve transcending the limit of validity prescribed by
law, then, ipso facto, the obligation to be fulfilled shall be
reduced to the limit of such validity. If from any such
circumstances the Bank shall ever receive anything of value deemed
interest under applicable law which would exceed interest at the
highest lawful rate, such excessive interest shall be applied to
the reduction of the principal amount owing hereunder, and not to
the payment of interest, or if such excessive interest exceeds any
unpaid balance of principal, such excess shall be refunded to the
Borrower. All sums paid or agreed to be paid to the Bank for the
use, forbearance or detention of monies included in the Loans
shall, to the extent permitted by applicable law, be amortized,
prorated, allocated and spread throughout the full term of such
indebtedness until payment in full so that the rate of interest on
account of such indebtedness is uniform throughout the term
thereof.  This Subsection 2.10 shall control every other provision
of the Loan Documents and all other agreements between the Bank and
the Borrower contemplated thereby.

     2.11 Renewal and Extension.  The parties anticipate that the
Bank may from time to time, in its sole and absolute discretion,
extend the Maturity Date (and thereby extend the Commitment Period)
upon request by the Borrower. The Bank shall not be obligated to
extend the Maturity Date at any time, and the Borrower acknowledges
that the Bank has not made any commitment, written or oral,
concerning extension of the Maturity Date. In the event the
Maturity Date is extended, the terms and provisions of this
Agreement will continue in full force and effect, except as may
otherwise be agreed in writing by the Borrower and the Bank.

     2.12 Reduction of Revolving Commitment. The Borrower may at
any time or from time to time permanently reduce the amount of the
Revolving Commitment by giving notice of the amount of such
reduction to the Bank and prepaying the amount by which the
principal balance of the then outstanding Revolving Advances
exceeds the reduced amount of the Revolving Commitment. Further,
the Borrower may terminate the Revolving Commitment at any time by
giving notice of such termination to the Bank and paying the entire
principal balance of the Revolving Note and all unpaid interest,
fees and other charges accrued in respect of the Revolving Loan.

3.   SECURITY.  As security for the prompt payment and performance
of the Indebtedness, at all times during the term of this Agreement
and until the Indebtedness is paid and satisfied in full:

     3.1  Collateral.  The Borrower will maintain and continue in
favor of the Bank a valid and perfected security interest in and to
the Collateral, which security interest shall be first and prior to
all other Liens. In order to provide the Bank with a valid and
perfected, first priority security interest in the Collateral, the
Borrower acknowledges that it has previously delivered in favor of
the Bank that certain Security Agreement dated May 19, 1995, and
appropriate UCC financing statements covering the Collateral, all
of which are hereby ratified and re-affirmed in all respects as
security for payment and performance of the Indebtedness. From time
to time after the Effective Date, the Borrower will, upon the
request of the Bank, promptly execute and deliver, or cause to be
executed and delivered, to the Bank such additional security
agreements, instruments, assignments, financing statements and
other documents, and do such other acts and things with respect to
the Collateral, as the Bank may reasonably deem necessary or
advisable to protect or perfect its interest in the Collateral.

     3.2  Negative Pledge.  Until payment in full of the
Indebtedness, the Borrower agrees that, without the prior written
consent of the Bank, it will not (i) create, assume or suffer to
exist any Lien on any of its Properties, except for Permitted
Liens, (ii) sell, transfer, assign or factor any of its
Receivables, or permit any Person to have any ownership right or
participation interest in any of its Receivables, or (iii) sell,
transfer or otherwise dispose of all or any substantial portion of
its other Properties, whether pursuant to a single transaction or
a series of transactions. Notwithstanding the foregoing:

          (a)  the Borrower shall be permitted to collect its
     Receivables and sell inventory, supplies and materials in the
     ordinary course of business;

          (b)  the Borrower shall be permitted to transfer, sell or
     otherwise dispose of Properties (other than Receivables) which
     are no longer used or useful in its business, provided that
     such sale, transfer or other disposition does not create a
     Default or Event of Default under any other provision of this
     Agreement;

          (c)  the Borrower shall be permitted to transfer to the
     Insurance Provider for collection any past-due Receivables as

     money security interests in equipment acquired by the Borrower
     after the Effective Date, provided that the Debt secured
     thereby does not exceed the limitations set forth in
     Subsection 7.3.1(iv) hereof.

     3.3   Grant of Liens Upon Default. Upon the occurrence of any
Event of Default, or at any time thereafter during the continuation
of such Event of Default, the Bank may, at its option, require the
Borrower to grant valid and enforceable first priority Liens in
favor of the Bank in and to all of its Properties.  Promptly upon
any such request, the Borrower shall execute and deliver to the
Bank such security agreements, financing statements, real estate
mortgages, deeds of trust and other collateral documents, in form
satisfactory to the Bank, as the Bank may request and as are
necessary in order to grant and convey to the Bank a first, prior
and perfected Lien in and to all of its Properties.

     3.4  Guaranty. The Guarantor hereby absolutely and
unconditionally guarantees the Borrower's prompt payment and
performance of the Indebtedness and further agrees to execute and
deliver the Guaranty to the Bank. The Guarantor acknowledges and
agrees that its obligations under the Guaranty will be in

Guarantor is a party have been duly authorized by all necessary
corporate action on its behalf.

     5.3  Validity and Binding Nature.  The Loan Documents to which
the Borrower and the Guarantor, as the case may be, is a party
constitute (or upon execution and delivery will constitute) its
valid and legally binding obligations, enforceable in accordance
with their respective terms (subject to any applicable bankruptcy,
insolvency and similar Laws affecting the enforcement of creditors'
rights generally and subject to general principles of equity).

     5.4  Conflicting Agreements and Restrictions.  Neither the
execution and delivery by the Borrower or the Guarantor of the Loan
Documents to which it is a party, nor fulfillment or compliance
with the terms and provisions thereof, will: (i) conflict with, or

or by which its Properties are bound; (ii) result in the creation
or imposition of any Lien on any of its Properties pursuant to the

     5.5  Actions and Proceedings; Contingent Debt. There is no
action, investigation or proceeding against the Borrower or the

     5.6  Financial Statements.  The audited financial statements
of the Borrower for the fiscal year ended December 31, 1995, and
the unaudited interim financial statements of the Borrower for the

end adjustments in the case of the financial statements for the
fiscal quarter ended September 30, 1996), and fairly present the
financial position of the Borrower as of the respective dates
thereof and for the periods stated. There has occurred no material
adverse change, either separately or in the aggregate, in the
financial position of the Borrower since September 30, 1996. The
Borrower does not have (i) any Debt which is not reflected in such
financial statements, but which, under GAAP, was required to be so

unrealized or anticipated losses from any commitments which are not
reflected in such financial statements.

Borrower is in compliance with the terms of all such Permits.

default of or in breach under any material contract, agreement or
instrument to which it is a party or by which it or any of its
Properties may be bound.

Default or Event of Default.

     9.6  Deposits; Setoff.  Regardless of the adequacy of any
other collateral security held by the Bank, any deposits or other
sums credited by or due from the Bank to the Borrower will at all
times constitute collateral security for the Indebtedness and may
be set off against the Indebtedness at any time, whether or not the
Indebtedness has been declared immediately due and payable.  The
rights granted by this Subsection 9.6 are in addition to the rights
of the Bank under any statutory banker's lien or the common law
right of set off.  This Subsection 9.6 shall not apply to any
monies of which the Borrower is not the beneficial owner,
regardless of the name in which the money is deposited, or to any
monies which the Borrower is contractually obligated to spend in
whole or in part for the account of others, provided that the
Borrower has established special accounts or given the Bank written
notice that particular funds are beneficially owned by others or
are dedicated for particular expenditures.  If the Borrower fails
to establish such special accounts and fails to give such notice,
the Bank may assume that funds on deposit to the account of the
Borrower belong solely to the named depositor and are subject to
this Subsection 9.6.

     9.7  Application of Payments.  During the continuation of any
Event of Default, all payments received by the Bank with respect to
the Indebtedness, whether from the Borrower,  the Guarantor,
recoveries upon the Collateral, or otherwise, may be applied by the
Bank to any liabilities, obligations or indebtedness included in
the Indebtedness selected by the Bank in its sole and exclusive
discretion.

10.  GENERAL PROVISIONS.  It is further agreed as follows:

     10.1 Participating Lender.  The Borrower understands that,
although the Revolving Note and the other Loan Documents name the
Bank as the holder thereof, the Bank may from time to time sell one
or more participation interests in the Revolving Loan to one or
more other financial institutions. The Borrower agrees that,
subject to the terms of the agreements of participation, each
participating lender will be entitled to rely on the terms of this
Agreement and the other Loan Documents as fully as if such
participating lender had been named as the holder of the Revolving
Note and the other Loan Documents.

     10.2 Hold Harmless.  Except for a successful claim against the
Bank by the Borrower, the Borrower will indemnify and hold the Bank
and each participant in the Revolving Note harmless from all
liability, loss, damages or expense, including reasonable
attorney's fees, that the Bank or any such participant may incur in
good faith as a result of entering into the Loan Documents or
establishing the Revolving Loan, or in compliance with or in the
enforcement of the terms of the Loan Documents.
