               intent of this Agreement, all as fully and effectively as

to be done by virtue hereof. This power-of-attorney is a power coupled with an
interest and shall be irrevocable.

     (b)  The powers conferred on Creditor and the other attorneys appointed
          hereunder are solely to protect the interests of Creditor in the
          Collateral and shall not impose any duty upon them to exercise any

          shall be accountable only for amounts that they actually receive as a
          result of the exercise of such powers, and neither they nor any of
          their officers, directors, employees or agents shall be responsible to
          Borrower for any act or failure to act, except for their gross
          negligence or willful misconduct.

     (c)  Borrower also authorizes Creditor, at any time and from time to time,
          (i) to communicate in its own name with any party to any contract,
          agreement or Account included in the Collateral with regard to the
          assignment thereof hereunder and other matters relating thereto; and
          (ii) to execute, in connection with the sale provided for in Section 9
          of this Agreement, any endorsements, assignments, bills of sale or
          other instruments of conveyance or transfer with respect to the
          Collateral.

     7. Performance by Creditor of Borrower's Obligations. If Borrower fails to
perform or comply with any of its agreements contained herein, under the
obligations or in any contract, agreement or instrument included in the
Collateral, and Creditor, as provided for by the terms of this Agreement, shall
itself perform or comply, or otherwise cause performance or compliance, with
such agreement, the expenses of Creditor incurred in connection with such
performance or compliance, together with interest thereon at the maximum lawful
interest rate permitted under the laws of the State of Oklahoma shall be payable
by Borrower to Creditor on demand and until such payment shall constitute
Obligations secured hereby. Creditor shall have the right to pay off any lien,
security interest or other encumbrance on the Collateral, regardless of whether
the

                                        5
<PAGE>

obligations secured by such lien, security interest or other encumbrance are due
and owing, and such amount shall constitute obligations secured hereby.

     8. Inspection Rights. Creditor is hereby given the right and privilege,
during regular business hours, of making such inspections of the Collateral and
records thereof as it deems necessary and of auditing or causing an audit or
verification of the books and records of Borrower relating to the Collateral at
any time and from time to time, including the contacting of customers or
suppliers of Borrower in connection with such audit or verification. Borrower
agrees to assist Creditor in every way necessary to facilitate such audits,
verifications and inspections.

     9. Remedies. If an Event of Default hereunder or under the obligations has
occurred and is continuing, Creditor may exercise, in addition to all other
rights and remedies granted to it in this Agreement, all rights and remedies of
a secured party under the Code or any other applicable law. Creditor, at its
option, may proceed as to all or any part of the Collateral in accordance with
its rights or remedies hereunder. Without limiting the generality of the
foregoing, Borrower expressly agrees that in any such event Creditor, without
demand of performance or other demand, advertisement or notice of any kind to or
upon Borrower or any other person (all and each of which demands, advertisements
and/or notices are hereby expressly waived), may forthwith collect, receive,
appropriate and realize upon the Collateral, or any part thereof, and/or may
forthwith sell, lease, license, assign, give option or options to purchase, or
sell or otherwise dispose of and deliver said Collateral (or contract to do so),
or any part thereof, in one or more parcels at public or private sale or sales,
at any exchange, broker's board or at any of Creditor's offices or the
Borrower's offices or elsewhere at such prices as it may deem best, for cash or
on credit or for future delivery without assumption of any credit risk, and
Creditor shall apply the net proceeds (after expenses) of any such sale, lease,
license, assignment or other disposition against the indebtedness secured hereby
in such order as Creditor in its sole discretion shall determine, Borrower
remaining liable for any deficiency therein. Creditor shall have the right upon
any such public sale or sales to purchase the whole or any part of the
Collateral so sold. To the extent permitted by applicable law, Borrower waives
all claims, damages and demands against Creditor arising out of the
repossession, retention, sale or license of the Collateral. In the event
Creditor is required by law to give written notice to Borrower of any
disposition of the Collateral, Borrower agrees that five (5) days' prior written
notice by Creditor to Borrower shall be deemed to be reasonable notice.

     10. Grant of License to Use Intangibles. For the purpose of enabling
Creditor to exercise rights and remedies under this Agreement at such time as
Creditor shall be lawfully entitled to exercise such rights and remedies and for
no other purpose, Borrower hereby grants to Creditor an irrevocable,
nonexclusive license (exercisable without payment of royalty or other
compensation to Borrower) to use, assign or sublicense any of the Collateral,
now owned or hereafter acquired by Borrower and wherever the same may be
located, including in such license reasonable access to all media in which any
of the licensed items may be recorded or stored and to all computer programs
used for the compilation or printout thereof. Until such time as Creditor is
entitled to exercise such rights and remedies Borrower is entitled to use the
Collateral without payment of royalty or other compensation to Creditor.

                                        6
<PAGE>

     11. Limitation on Creditor's Duty in Respect of Collateral. Beyond the use
of reasonable care in the custody and preservation thereof, Creditor shall not
have any duty as to any Collateral in its possession or control or in the
possession or control of its agent or nominee or any income thereon or as to the
preservation of rights against prior parties or any other rights pertaining
thereto.

     12. Further Assurances, Etc. Borrower authorizes Creditor to sign and file
financing statements, continuation statements and any other forms, filings or
other statements required or permitted under the Code at any time and from time
to time with respect to the Collateral without Borrower's signature and on
Borrower's behalf. Borrower will, however, at any time upon Creditor's request,
sign financing statements, continuation statements, trust receipts, security
agreements or other agreements, forms, filings or other statements with respect
to the Collateral. Upon the failure of Borrower to do so, Creditor is authorized
as Borrower's agent to sign any such instrument or agreement. Borrower agrees
that at any time and from time to time upon the written request of Creditor,
Borrower will promptly execute and deliver any and all such further instruments
and documents and do such further acts as Creditor may reasonably request in
order to carry out more effectively the purposes of this Agreement and obtain
for Creditor the full benefits of the security interests granted to Creditor
hereby.

     13. Notices. All notices and other communications required or permitted to
be made by one party to the other under this Agreement shall be given in writing
to the addresses of the parties set forth next to their signatures subject to
each party's right to change such notice address upon giving the other party
written notice in compliance with this Section.

     14. Partial Invalidity. If any term, covenant or condition of this
Agreement or the application thereof to any person or circumstance shall, to any
extent, be invalid or unenforceable, the remainder of this Agreement, or the
application of such term, covenant or condition to persons or circumstances
other than those as to which it is held invalid or unenforceable, shall not be
affected thereby and each term, covenant or condition of this Agreement shall be
held valid and be enforced to the fullest extent permitted by law.

     15. No Waiver; Cumulative Remedies. Creditor shall not by any act, delay,
and omission or otherwise be deemed to have waived any of its rights or remedies
hereunder, and no waiver shall be valid unless in writing, signed by Creditor,
and then only to the extent therein set forth. A waiver by Creditor of any right
or remedy hereunder on any one occasion shall not be construed as a bar to any
right or remedy which Creditor would otherwise have had on any future occasion.
No failure to exercise nor any delay in exercising on the part of Creditor any
right, power or privilege hereunder shall operate as a waiver thereof, nor shall
any single or partial exercise of any right, power or privilege hereunder
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege. The rights and remedies hereunder provided are
cumulative with any rights and remedies under the Note or any other loan
document and may be exercised singly or concurrently, and are not exclusive of
any rights and remedies provided by law or equity.

     16. Limitations by Law. All rights, remedies and powers provided by this
Agreement may be exercised only to the extent that the exercise thereof does not
violate any applicable provision of law, and all the provisions of this
Agreement are intended to be subject to all

                                        7
<PAGE>

applicable mandatory provisions of law which may be controlling and to be
limited to the extent necessary so that they will not render this Agreement
invalid, unenforceable in whole or in part or not entitled to be recorded,
registered or filed under the provisions of any applicable law.

     17. Binding Effect. This Agreement and all the covenants and agreements
herein will be binding upon and inure to the benefit of the parties hereto and
their respective successors in interest and assigns. The Creditor shall at all
times have the right to assign its rights and interest under this Agreement.

     18. Applicable Law. This Agreement shall be governed by, and be construed
and interpreted in accordance with, the laws of the State of Oklahoma and the
United States.

     19. Venue. The parties agree that jurisdiction and venue for any matter
arising out of or pertaining to this Agreement shall be proper only in the state
courts located in Tulsa County, Oklahoma and the federal courts having
jurisdiction over the Northern District of Oklahoma, and the parties hereby
consent to such venue and jurisdiction.

     IN WITNESS WHEREOF the parties have caused this Agreement to be executed as
of the day and year first set forth above.
