A.  To induce the Lender to extend credit to the Debtor and for
  other good and valuable consideration, the receipt of which is
  acknowledged, and for the purpose of enabling the Debtor to
  obtain or renew loans, credit or other financial accommodation
  from the Lender named above, each of the undersigned as a
  primary obligor, jointly and severally and unconditionally:
  (I) guarantees to the Lender that Debtor will fully and
  promptly pay or otherwise discharge all indebtedness and other
  obligations ("indebtedness") upon which Debtor now is or may
  later, from time to time, become obligated to Lender as
  principal, guarantor, endorser, or in any other capacity, and
  whether joint or several liability or liability created by
  direct dealing with Lender or through transfer from others,
  and regardless of the nature and form of indebtedness and
  whether due or not due; (2) agrees, without the Lender first
  having to proceed against Debtor or any other party liable or
  to liquidate any security, to pay on demand all sums due and
  to become due to Lender from Debtor, and all losses, costs,
  attorney fees or expenses which may be suffered or incurred by
  Lender by reason of Debtor's default or the default of the
  undersigned; (3) except as setoff is waived, agrees to be
  bound by and on demand to pay any deficiency or difference
  between all indebtedness of the Debtor and the proceeds of any
  private or public sale (including a sheriff's sale) of the
  security held by Lender, with or without notice to the
  undersigned; (4) agrees that liability under this Agreement
  will not be affected or impaired by any failure, neglect or
  omission, including a failure or delay to perfect or maintain
  perfection of a security interest, either in relation to the
  collection of the indebtedness or the protection of the
  security given, and regardless of whether the Lender fails or
  omits to seek or is precluded from seeking a judgment against
  Debtor; and (5) further agrees that the liability of the
  undersigned shall not be affected by any lack of validity or
  enforceability due to defense, claim, discharge or otherwise
  of any indebtedness guaranteed by this Agreement or of the
  security of the indebtedness.

B.  Lender may at any time and from time to time without the
  further consent of or notice to the undersigned, without
  incurring responsibility to the undersigned and without
  impairing or releasing the obligations of the undersigned, and
  upon any terms and conditions the Lender may elect: (1) change
  the manner, place or terms of payment or extend the time of
  payment of any indebtedness of Debtor to Lender; (2) renew,
  increase or alter any indebtedness of Debtor to Lender; (3)
  raise or lower the interest rate or rates charged Debtor; (4)
  sell, exchange, release, surrender, realize upon or
  otherwise deal or not deal with in any manner and in any order
  any property at any time pledged to secure or securing the
  indebtedness of Debtor to Lender or any liabilities incurred
  directly or indirectly under this Agreement, or any offsets
  against any such indebtedness or liabilities; (5) exercise or
  refrain from exercising any rights against Debtor or others,
  or otherwise act or refrain from acting; (6) settle or
  compromise any indebtedness guaranteed or incurred; (7)
  subordinate the payment of all or part of any indebtedness of
  Debtor to Lender to the payment of any liabilities which may
  be due Lender or others; (8) apply any sums paid by or for
  account of Debtor to any indebtedness of Debtor to Lender
  regardless of what indebtedness or liability of Debtor to
  Lender remains unpaid and regardless of to which indebtedness
  such sums were intended to be applied; (9) release any one or
  more of the undersigned, any other guarantor or any other
  party liable upon or for any indebtedness or other obligation
  guaranteed, and such release will not affect the liability
  under this Agreement of any of the undersigned or any other
  party not so released; (10) add or release the primary or
  secondary liability of principals, guarantors, or other parties;
  and/or (11) obtain additional collateral security.

C.  The undersigned waives: (1) any and all acceptance of this
  Guaranty Agreement; (2) notice of the creation of any
  indebtedness; (3) any presentment, demand for payment, notice
  of default or non-payment, notice of acceleration, notice of
  disposition of security, notice of dishonor or protest to or
  upon any party and all other notices whatsoever whether
  required or permitted by this Guaranty Agreement, any other
  agreement, course of dealing, usage of trade, course of
  performance and, to the extent allowed, the law; (4) any
  exercise of any remedy which the Lender now has or later
  acquires against the Debtor or any other party; (5) any
  impairment of collateral, including, but not limited to, the
  failure to perfect, or maintain perfection of, a security
  interest in collateral; and (6) any event, or any act or
  omission of the Lender (except acts or omissions in bad faith)
  which materially increases the scope of the undersigned's risk
  as guarantor, including the manner of administration of the
  loan and changes in the form or manner in which any party does
  business or in their financial condition and any notice of any
  such change.

D.  This Guaranty Agreement shall be absolute, unconditional and
  continuing guaranty of payment and not of collection and shall
  be binding upon the undersigned, heirs or successors of the
  undersigned, and the estate or estates of the undersigned: (I)
  regardless of the death or cessation of existence of any of
  the undersigned or of any guarantor or any other party liable
  upon any indebtedness or other obligation hereby guaranteed;
  (2) irrespective of any defenses, claim or discharge available
  to the Debtor under law or under any agreement with the
  Lender; and (3) irrespective of any failure or delay by the
  Lender to perfect or keep perfected any lien or security
  interest in any collateral. This Guaranty Agreement is an
  independent obligation which is separately enforceable from
  the obligation of the Debtor.

E.  All rights of the Lender are cumulative and not alternative to
  other rights. Suit may be brought against the undersigned or
  other parties liable, jointly and severally, and against any
  one or more of them, and against all or less than all, without
  impairing the rights of the Lender, its successors or assigns,
  against others of the undersigned. The Lender may settle with
  any one of the undersigned or any other party for such sum or
  sums as it may see fit and release such of the undersigned or
  other parties from all further liability to the Lender for
  such indebtedness without impairing the right of the Lender to
  demand and collect the balance of such indebtedness from
  others of the undersigned not so released.

F.  The Lender may assign this Agreement or any of its rights and
  powers under it, with all or any part of the indebtedness
  guaranteed, and may assign to any such assignee any of the
  security for the indebtedness. In the event of such
  assignment, the assignee shall have the same rights and
  remedies as if originally named in this Agreement in place of
  Lender, and the Lender shall thereafter be fully discharged
  from all responsibility with respect to any such indebtedness
  so assigned.

G.  Unless expressly limited by specific writing as set forth in
  this Guaranty Agreement, it is understood to be unlimited in
  amount. If limited, it is understood the limit means a fixed
  amount or percentage of any indebtedness remaining after
  application of the actual proceeds of the disposition of any
  security to any unguaranteed portion of the indebtedness.

H.  Until the indebtedness of the Debtor have been paid in full,
  the undersigned agrees to provide to the Lender from time to
  time upon demand such financial statements, copies of tax
  returns, and other information as to the undersigned as the
  Lender may reasonably requrre.

I.  Any deposits or other sums credited by or due from the Lender
  to the undersigned may be set off against any and all
  liabilities of the undersigned to the Lender arising under the
  terms of this Guaranty Agreement. The rights granted by this
  paragraph shall be in addition to the rights of the Lender
  under any statutory banker's lien or common law right of
  offset.

J.  Until the obligations of the Debtor have been paid in full,
  the undersigned specifically waives all rights of subrogation
  to the rights of the Lender, any claim to any security or its
  value to which the Lender has recourse, and all rights of
  reimbursement or contribution from other parties, whether
  principals or sureties, accommodation parties or guarantors.

K.  The undersigned may, only by written notice given to and
  received by Lender, withdraw only from liability for
  additional indebtedness of Debtor accepted by or incurred to
  Lender after the time of receipt of such notice by Lender. The
  liability and other agreements of the undersigned shall not be
  otherwise affected but shall continue until all indebtedness,
  including loan commitments, existing at the time of the
  receipt of such notice, and renewals or extensions of
  indebtedness to which the undersigned consents, is fully paid.
  After any such revocation, Lender may exercise any rights
  granted in this Agreement without releasing the undersigned
  from liability.

L.  Notwithstanding the provisions of any note or obligation to
  which this Guaranty Agreement applies, it is the intention of
  the parties, and it is here provided, that a Guarantor shall
  not be liable for interest charges in excess of the maximum
  amount permitted under the law applicable to this Guaranty
  Agreement.

M.  The undersigned specifically waives any right to setoff under
  12 O.S. sec. 686, 15 0.S. sec. 341, or any like statutes, and
  agree that the Lender may apply the actual proceeds from the
  disposition of any security first to any unguaranteed portion
  of the indebtedness. Any party to this Guaranty Agreement has
  right to waive trial by jury and waives all objections to
  venue in any action instituted by the Lender arising out of
  this Guaranty Agreement.

N.  The undersigned waive, as of the date of this Guaranty
  Agreement, any claim, as that term is defined in the Federal
  Bankruptcy Code, which the undersigned might have or acquire
  against the Debtor arising from the existence or performance
  of the undersigned's obligations under this Guaranty
  Agreement, and to that extent that the undersigned is not a
  creditor of the Debtor. In addition to the waiver of the
  status of creditor, it is agreed that the indebtedness
  guaranteed under this Guaranty Agreement excludes all portions
  of the indebtedness paid by the Debtor during the period of
  time within one year prior to the filing of any bankruptcy,
  reorganization or insolvency proceedings by or against the
  Debtor. If any payment made by the Debtor to the Lender is
  determined to be avoidable under applicable state law or the
  Federal Bankruptcy Code, to that extent, if demanded by the
  Lender, this Guaranty Agreement is deemed to be reinstated to
  include the amount within the indebtedness under this Guaranty
  Agreement.

0.  The undersigned, by signing below, acknowledge having read
  this Guaranty Agreennent, having reviewed it to the extent
  desired with their legal counsel, and receiving a copy of it
  and also receiving an explanation of any questions. The
  undersigned also have read any cosigner notice provided by
  Lender. The undersigned understand that the undersigned may
  have to pay any indebtedness or obligation covered by this
  Guaranty Agreement in the event the Debtor fails or refuses to
  do so. The undersigned also represent that they are aware of
  the financial condition of Debtor and acknowledge a
  responsibility to maintain a close watch on that financial
  condition as long as this Guaranty Agreement is outstanding
  and that they are not relying on the Lender to provide
  information on the Debtor's financial condition, now or in the
  future.

P.  Any cause of action for a breach or enforcement of, or a
  declaratory judgment respecting, this agreement or any
  agreement related to the execution and delivery of this
  agreement shall be commenced and maintained only in the United
  States District Court for the Northern District of Oklahoma or
  the applicable Oklahoma state trial court sitting in Tulsa,
  Oklahoma and having subject matter jurisdiction; provided,
  however, any action to foreclose any deed of trust or real
  estate mortgage securing finance or repayment shall be
  brought in any county having mandatory venue thereof pursuant
  to the venue statutes of the State of Oklahoma.

Q.  This Guaranty Agreement constitutes the entire agreement
  between the parties with respect to the obligations of the
  undersigned and the rights of the Lender under this Guaranty
  Agreement. This Guaranty Agreement cannot be amended except by an
  agreement in writing signed by both the undersigned and the
  Lender. No condition as to the effectiveness or enforcement of
  this Guaranty Agreement exists except as stated in this Guaranty
  Agreement. Regardless of any other provision of this Guaranty
  Agreement to the contrary, and unless otherwise specifically
  released or modified by this Guaranty Agreement, all other
  obligations of the undersigned to Lender evidenced by a note,
  loan agreement, guaranty or any other written agreement remain in
  force and effect.
