     (g) Buy (or allow Secured Party to buy) Collateral, or any part thereof, at any
private sale if any Collateral is of a type customarily sold in a recognized market or is of a type
that is the subject of widely distributed standard price quotations.



     (h) Apply by appropriate judicial proceedings for appointment of a receiver for the
Collateral, or any part thereof, and Debtor consents to any such appointment.



     (i) Comply with any applicable state or federal Law requirement in connection with a
disposition of Collateral and such compliance shall not be considered to affect adversely the
commercial reasonableness of any sale of Collateral.



     (j) Sell Collateral without giving any warranty, with respect to title or any other
matter.



     (k) To the extent notice of sale shall be required by law with respect to
Collateral, at least ten (10) Business Days’ notice to Debtor of the time and place of any public
sale or the time after which any private sale is to be made shall constitute reasonable
notification; provided that, if Secured Party fails in any respect to give such notice, its
liability for such failure shall be limited to the liability (if any) imposed on it by law under
the UCC. Secured Party shall not be obligated to make any sale of Collateral regardless of notice
of sale having been given. Secured Party may adjourn any public or private sale from time to time
by announcement at the time and place fixed therefor, and such sale may, without further notice, be
made at the time and place to which it was so adjourned.

     Section 6.3. Application of Proceeds. If an Event of Default shall have occurred and be
continuing, any cash held by or on behalf of Secured Party and all cash proceeds received by or on
behalf of Secured Party in respect of any sale of, collection from, or other realization upon any
Collateral may, in the discretion of Secured Party, be held by Secured Party as collateral for,
and/or then or at any time thereafter applied in whole or in part by Secured Party against, any
Obligation, in the following manner:



     (a) First, to Secured Party for any amounts then owing to Secured Party for
costs or expenses incurred by Secured Party in connection therewith.



     (b) Second, to Secured Party in repayment of the Obligations.



     (c) Third, any surplus of such cash or cash proceeds held by or on the
behalf of Secured Party and remaining after payment in full of all the Obligations shall be paid
over to the Debtor or to whatever Person may be lawfully entitled to receive such surplus.



     Section 6.4. Private Sales of Pledged Equity. Secured Party may deem it impracticable to
effect a public sale of any Pledged Equity and may determine to make one or more private sales of
such Pledged Equity to a restricted group of purchasers that will be obligated to agree, among
other things, to acquire the same for their own account, for investment and not with a view to the
distribution or resale thereof. Any such private sale may be at a price and on other terms less
favorable to the seller than the price and other terms that might have been obtained at a public
sale. Any such private sale nevertheless shall be deemed to have been made in a commercially
reasonable manner, and Secured Party shall not have any obligation to delay sale of any such
Pledged Equity for the period of time necessary to permit their registration for public sale under
the Securities Act. Any offer to sell any such Collateral that has been:




     (i) publicly advertised on a bona-fide basis in a newspaper or other publication of
general circulation in the financial communities of New York, New York, Houston, Texas and
Oklahoma City, Oklahoma (to the extent that such an offer may be so advertised without prior
registration under the Securities Act), or




     (ii) made privately in the manner described above to not less than 15 bona-fide
offerees,




     (iii) shall be deemed to involve a “public disposition” under Chapter 9.610(c) of
the UCC, notwithstanding that such sale may not constitute a “public offering” under the
Securities Act, and Secured Party may bid for such Collateral.



     Section 6.5. Non-Judicial Remedies. In granting to Secured Party the power to enforce
its rights hereunder without prior judicial process or judicial hearing, to the extent permitted by
applicable Law, Debtor waives, renounces and knowingly relinquishes any legal right that might
otherwise require Secured Party to enforce its rights by judicial process and confirms that such
remedies are consistent with the usage of trade, are responsive to commercial necessity and are the
result of a bargain at arm’s length. Secured Party may, however, in its discretion, resort to
judicial process.



     Section 6.6. Limitation on Duty of Secured Party in Respect of Collateral. Beyond the
exercise of reasonable care in the custody thereof, Secured Party shall have no duty as to any
Collateral in its possession or control or in the possession or control of any agent or bailee or
as to the preservation of rights against prior parties or any other rights pertaining thereto.
Secured Party shall be deemed to have exercised reasonable care in the custody of Collateral in its
possession if such Collateral is accorded treatment substantially equal to that which it accords
its own property, and Secured Party shall not be liable or responsible for any loss or damage to
any Collateral, or for any diminution in the value thereof,

by reason of the act or omission of any warehouseman, carrier, forwarding agency, consignee or
other agent or bailee selected by Secured Party in good faith.

Miscellaneous



     Section 7.1. Notices. Any notice or communication required or permitted hereunder shall be

shall be effective only if given with the necessary approvals required in the Credit Agreement.



     Section 7.3. Preservation of Rights. No failure on the part of Secured Party to exercise,
and no delay in exercising, any right hereunder or under any other Loan Document shall operate as a

further exercise thereof or the exercise of any other right. The rights and remedies of Secured
Party provided herein and in the other Loan Documents are cumulative and are in addition to, and
not exclusive of, any rights or remedies provided by Law or otherwise.



     Section 7.4. Severability. Any provision of this Security Agreement that is prohibited or

Debtor herein shall survive the execution and delivery of this Security Agreement, the execution
and delivery of any other Loan Document and the creation of the Obligations.



     Section 7.6. Binding Effect and Assignment. This Security Agreement shall:



     (a) be binding on Debtor and its successors and permitted assigns, and



     (b) inure, together with all rights and remedies of Secured Party hereunder, to the
benefit of Secured Party and its successors, transferees and permitted assigns.


Without limiting the generality of the foregoing, Secured Party may (except as otherwise provided
in any Loan Document) pledge, assign or otherwise transfer any right under any Loan Document to any
other Person, and such other Person shall thereupon become vested with all benefits in respect
thereof granted herein or otherwise. No right or duty of Debtor hereunder may be assigned or
otherwise transferred without the prior written consent of Secured Party.




     Section 7.7. Release of Collateral; Termination.

     (a) Upon any sale, lease, transfer or other disposition of any Collateral of Debtor
in accordance with the Loan Documents or the Asset Sale Agreement, Secured Party will, at Debtor’s
expense, execute and deliver to Debtor such documents as Debtor shall reasonably request to
evidence the release of such Collateral from the assignment and security interest granted hereby;
provided that:




     (i) Debtor shall have complied with the notice requirements and the other requirements
of Section 10.01(b) of the Credit Agreement and any applicable provisions of the Asset Sale
Agreement, and




     (ii) if any Loan Document provides for any application of the proceeds of any such
sale, lease, transfer or other disposition, or any payment to be made, in connection
therewith, such proceeds shall have been applied or payment made as provided therein.



     (b) Upon, and only upon the indefeasible payment and satisfaction in full in cash of
the Obligations or the satisfaction and discharge of the Obligations pursuant to the Asset Sale
Agreement,, this Security Agreement and the security interest created hereby shall terminate, all
rights in the Collateral shall revert to Debtor and Secured Party, at a Debtor’s request and at its

not have been sold or otherwise disposed of or applied pursuant to the terms hereof, and

evidence such termination.



     (c) Debtor is not authorized to file any financing statement or amendment or
termination statement with respect to any financing statement originally filed in connection with
this Security Agreement without the prior written consent of Secured Party, subject to Debtors’
rights under Chapters 9.509(d)(2) and 9.518 of the UCC.

accordance with the laws of the State of New York.

represent the final agreement between the parties hereto and may not be contradicted by evidence of
prior, contemporaneous, or subsequent oral agreements of the parties hereto. There are no
unwritten oral agreements between the parties hereto.



     Section 7.10. Counterparts; Facsimile. This Security Agreement may be executed in any
number of counterparts (and by different parties hereto in different counterparts), each of which
when so executed shall be deemed to be an original and all of which when taken together shall
constitute one and the same agreement. Delivery of an executed counterpart of a signature page of
this Security Agreement by telecopy, facsimile, photocopy or by sending a scanned copy by
electronic mail shall be effective as delivery of a manually executed counterpart of this Security
Agreement.
