The Pledgor, for value received, the receipt and sufficiency of which are hereby acknowledged, and to induce the Lender to issue Letters of Credit for the benefit of the Corporation, hereby pledges to the Lender and hereby grants to the Lender a first lien on and a security interest in the Collateral to secure the Obligations. 2.2 Delivery of Securities. All certificates or instruments representing or evidencing the Securities shall be delivered to and held by the Lender for the sole purpose of possession of the Collateral or any portion thereof pursuant to this Security Agreement, and shall be in suitable form for transfer by delivery, or shall be accompanied by duly executed instruments of transfer or assignment in blank, all in form and substance satisfactory to the Lender. The Lender shall at all times have actual possession of the Securities and shall be deemed to have possession of any of the Collateral in transit to it or set apart for it. 2.3 Power of Attorney. The Pledgor hereby irrevocably constitutes and appoints the Lender and any authorized officer or agent thereof, with full power of substitution, as its true and lawful attorney-in-fact with full irrevocable power and authority in the place and stead of the Pledgor and in the name of the Pledgor or in its own name, from time to time in the Lender's discretion, for the purpose of carrying out the terms of this Security Agreement, and without notice to the Pledgor, to take any and all appropriate action and to execute any and all documents and instruments which may be necessary or desirable to accomplish the purposes of this Security Agreement, including, without limitation, the following: (a) upon the occurrence and during the continuance of any Event of Default, to transfer to or register any or all of the Collateral in the name of the Lender or any of its nominees; (b) to exchange the certificates or instruments representing or evidencing the Collateral for certificates or instruments of smaller or larger denominations; (c) upon the occurrence and during the continuance of any Event of Default, (i) to receive payment of and receipt for any and all moneys, claims and other amounts due and to become due at any time in respect of or arising out of any Collateral, (ii) to commence and prosecute any suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect the Collateral or any part thereof and to enforce any other right in respect of any Collateral, (iii) to defend any suit, action or proceeding brought against the Pledgor with respect to any Collateral, (iv) to settle, compromise or adjust any suit, action or proceeding described above and, in connection therewith, to give such discharges or releases as the Lender may deem appropriate, and (v) to complete any blanks contained in any instruments of transfer or assignment appended to or delivered with the certificates representing the Securities; and (d) to exchange any of the Collateral for other property upon reorganization, recapitalization or other readjustment of the Corporation, and in connection therewith to deposit any of the Collateral with any committee or depository upon such terms as the Lender may determine; and, subsequent to any Event of Default, to exercise, at the option of the Lender, voting rights as to any of the Collateral; all without notice and without liability except to account for property actually received by the Lender. The Pledgor hereby ratifies all that said attorney shall lawfully do or cause to be done within the scope of the power of attorney granted hereunder. This power of attorney is a power coupled with an interest and shall be irrevocable so long as any Obligation remains outstanding or any Commitment exists. The powers conferred on the Lender hereunder are solely to protect its interests in the Collateral and shall not impose any duty upon it to exercise any such powers. The Lender shall be accountable only for amounts that it actually receives as a result of the exercise of such powers and neither it nor any of its officers, directors, employees or agents shall be responsible to the Pledgor for any act or failure to act, except for gross negligence. ARTICLE 3 REPRESENTATIONS AND WARRANTIES To induce the Lender to enter into the Credit Agreement and issue Letters of Credit for the account of the Corporation, the Pledgor represents and warrants to the Lender (which representations and warranties shall survive the delivery of this Security Agreement and the other Loan Documents) that: 3.1 Status of Securities.

No information, exhibit, or report furnished by the Pledgor to the Lender in connection with the negotiation of any Loan Document contained or contains any material misstatement of fact or omitted to state a material fact or any fact necessary to make the statements contained therein, in light of the circumstances in which they were made, not misleading. 3.3 Ownership and Liens. Except for the security interest of the Lender, the Pledgor owns (and at the time of transfer or delivery of the Collateral to the Lender owned or will own) good and indefeasible title to the Collateral free and clear of any other security interests, liens, adverse claims, or options; the Pledgor has (and at the time of transfer or delivery of the Collateral to the Lender had or will have) full right, power, and authority to convey, assign, transfer, and deliver the Collateral to the Lender and to grant a security interest in the Collateral to the Lender in the manner provided herein. ARTICLE 4 COVENANTS AND AGREEMENTS Unless agreed in writing by the Lender to the contrary, the Pledgor agrees, so long as any Obligation remains outstanding or unpaid or any Commitment exists: 4.1 Payment of Assessments and Charges. To pay all taxes, charges, liens and assessments against the Collateral; and upon the failure of the Pledgor to do so, the Lender at its option may, but will not be obligated to, pay any of them. 4.2 Delivery of Collateral. That any and all (i) dividends paid or payable other than in cash and all instruments and other property received, receivable or otherwise distributed in respect of or in exchange for any Collateral, (ii) dividends and other distributions paid or payable in cash in respect of any Collateral in connection with a partial or total liquidation or dissolution or in connection with a reduction of capital, capital surplus or paid-in surplus, and (iii) cash paid, payable or otherwise distributed in respect of principal of, in redemption of or in exchange for any Collateral, shall be forthwith delivered to the Lender to hold as Collateral for the benefit of the Lender and shall, if received by the Pledgor, be received in trust for the benefit of the Lender, be segregated from the other property or funds of the Pledgor, and be forthwith delivered to the Lender as Collateral in the same form as so received (with any necessary endorsement). 4.3 Further Assurances. To promptly cure any defects in the execution and delivery of any of the Loan Documents executed by the Pledgor and execute, acknowledge, and deliver such other assurances and instruments and take such other action as shall, in the opinion of the Lender, be necessary to fulfill the terms of the Loan Documents executed by the Pledgor and to confirm, perfect, and preserve the security interest created and intended to be created hereby and to vest more completely in and assure to the Lender its rights under this Security Agreement. 4.4 Prohibited Liens and Filings. That it will not pledge, mortgage, or otherwise encumber, create, or suffer a security interest to exist in any of the Collateral (other than in favor of the Lender) or sell, assign, or otherwise transfer any of the Collateral to anyone other than the Lender or file or permit to be filed any financing statement or other security instrument with respect to the Collateral other than in favor of the Lender. ARTICLE 5 RIGHTS AND REMEDIES 5.1 Remedies Upon Default. (a) Upon the occurrence and during the continuance of an Event of Default, the Lender may, at its option, declare all Obligations immediately due and payable, without presentment, demand, protest, notice of protest, default or dishonor, notice of intent to accelerate maturity, notice of acceleration of maturity or other notice of any kind, all of which are hereby expressly waived by the Pledgor, and may exercise any and all other remedies provided by law or pursuant to the Loan Documents. (b) If all or any part of the Obligations shall become due and payable, the Lender may then, or at any time thereafter, apply, set-off, collect, sell in one or more sales, or otherwise dispose of, any or all of the Collateral, in its then condition or following any commercially reasonable preparation or processing, in such order as the Lender may elect. Any such sale may be made either at public or private sale at the place of business of the Lender, any brokers' board or securities exchange or elsewhere, either for cash or upon credit or for future delivery, at such price as the Lender may deem fair. The Lender may be the purchaser of any or all Collateral so sold and may hold the same thereafter in its own right free from any claim of the Pledgor or right of redemption. No such purchase or holding by the Lender shall be deemed a retention by the Lender in satisfaction of the Obligations. All demands, notices, and advertisements, and the presentment of property at sale are hereby waived. If, notwithstanding the foregoing provisions, any applicable provision of the Uniform Commercial Code or other law requires the Lender to give reasonable notice of any such sale or disposition or other action, ten days' prior written notice shall constitute reasonable notice. The Lender may require the Pledgor to assemble the Collateral and make it available to the Lender at a place designated by the Lender that is reasonably convenient to the Lender and the Pledgor. Any sale hereunder may be conducted by an auctioneer or any officer or agent of the Lender. (c) In connection with the sale of Collateral which is stock or other investment securities, the Lender must limit prospective purchasers to the extent deemed necessary or advisable by the Lender to render such sale exempt from the registration requirements of the Securities Act of 1933, as amended (the "Act"), and any applicable state securities laws. No sale so made in good faith by the Lender shall be deemed not to be "commercially reasonable" because so made; provided, however, that nothing in this Security Agreement shall be deemed to impose any obligation whatsoever to file a registration statement under the Act or any state securities law with respect to any sale of Collateral by the Lender. 5.2 Voting Rights, Dividends, Etc. Prior to Default. So long as no Event of Default shall have occurred and be continuing: (a) the Pledgor will be entitled to exercise any and all voting and other consensual rights pertaining to the Collateral or any part thereof for any purpose not inconsistent with the terms of this Security Agreement; (b) subject to the further provisions of this Security Agreement, the Pledgor shall be entitled to receive and retain any and all dividends paid in respect of the Collateral; provided, however, that any and all (i) dividends paid or payable other than in cash and all instruments and other Property received, receivable, or otherwise distributed in respect of or in exchange for any Collateral, (ii) dividends and other distributions paid or payable in cash in respect of any Collateral in connection with a partial or total liquidation or dissolution or in connection with a reduction of capital, capital surplus or paid-in surplus, and (iii) cash paid, payable or otherwise distributed in respect of principal of, in redemption of or in exchange for any Collateral, shall be forthwith delivered to the Lender to hold as Collateral for the benefit of the Lender and shall, if received by the Pledgor, be received in trust for the benefit of the Lender, be segregated from the other property or funds of the Pledgor, and be forthwith delivered to the Lender as Collateral in the same form as so received (with any necessary endorsement); and (c) the Lender shall execute and deliver (or cause to be executed and delivered) to the Pledgor all such proxies and other instruments as the Pledgor may reasonably request for the purpose of enabling the Pledgor to exercise the voting and other rights which it is entitled to exercise pursuant to Section 5.2(a) above and to receive the dividends which it is authorized to receive and retain. 5.3 Voting Rights, Dividends, Etc. After Default. Upon the occurrence and during the continuance of an Event of Default: (a) at the option of the Lender with notice to the Pledgor, all rights of the Pledgor to exercise the voting and other consensual rights which it would otherwise be entitled to exercise pursuant to Section 5.2(a) above and to receive the dividends and interest payments which it would otherwise be authorized to receive and retain pursuant to Section 5.2(b) above shall cease and shall thereupon become vested in the Lender, who shall thereupon have the sole right to exercise such voting and other consensual rights and to receive and hold as Collateral such dividends; and (b) all dividends which are received by the Pledgor contrary to the provisions of Section 5.3(a) above shall be received in trust for the benefit of the Lender, shall be segregated from other funds of the Pledgor and shall be forthwith paid over to the Lender as Collateral in the same form as so received (with any necessary endorsement). 5.4 Proceeds. Prior to all or any part of the Obligations becoming due and payable as specified in Section 5.1, all cash sums or other property received by the Lender on account of the Collateral shall be held as Collateral. After all or any part of the Obligations shall become due and payable as specified in Section 5.1, the proceeds of any sale or other disposition of the Collateral and all sums received or collected by the Lender from or on account of the Collateral shall be applied by the Lender in the manner set forth in 9.504 of the UCC. 5.5 Lender Duties. The Lender shall be under no duty whatsoever to make or give any presentment, demand for performance, notice of nonperformance, protest, notice of protest, notice of dishonor, or other notice or demand in connection with any Collateral or the Obligations, or to take any steps necessary to preserve any rights against prior parties. The Lender shall not be liable for failure to collect or realize upon any or all of the Obligations or Collateral, or for any delay in so doing, nor shall the Lender be under any duty to take any action whatsoever with regard thereto. The Lender shall use reasonable care in the custody and preservation of any Collateral in its posses sion. The Lender shall have no duty to comply with any recording, filing, or other legal requirements necessary to establish or maintain the validity, priority, or enforceability of, or the Lender's rights in or to, any of the Collateral. 5.6 The Lender's Actions. The Pledgor waives any right to require the Lender to proceed against any person, exhaust any collateral or pursue any other remedy in the Lender's power; waives any and all notice of acceptance of this Security Agreement or of creation, modification, renewal, or extension for any period of any Obligations; and waives any defense arising by reason of any disability or other defense of the Corporation or any other guarantor or Person primarily or secondarily liable with respect to all or any portion of the Obligations ("Other Liable Party"), or by reason of the cessation from any cause whatsoever of the liability of the Corporation or any Other Liable Party. All dealings between the Corporation or the Pledgor and the Lender shall conclusively be presumed to have been had or consummated in reliance upon this Security Agreement. Until all Obligations shall have been paid and/or performed in full and the Commitment shall have terminated, the Pledgor (i) shall have no right to subrogation, (ii) waives any right to enforce any remedy that the Lender now has or may hereafter have against the Corporation or any Other Liable Party, and (iii) except as otherwise expressly provided in this Security Agreement, waives any benefit of and right to participate in any collateral or security whatsoever now or hereafter held by the Lender. ARTICLE 6 MISCELLANEOUS 6.1 Transfer of Obligations and Collateral. Subject to the terms of the Credit Agreement, the Pledgor hereby agrees that the Lender may transfer any or all of the Obligations. Upon any such transfer, the Lender may transfer any or all of the Collateral and shall be fully discharged thereafter from all liability with respect to the Collateral so transferred, and the transferee shall be vested with all rights, powers, and remedies of the Lender hereunder with respect to Collateral so transferred. With respect to any Collateral not so transferred, the Lender shall retain all rights, powers, and remedies hereby given. The Lender may at any time deliver any or all of the Collateral to the Pledgor, whose receipt shall be a complete and full acquittance for the Collat eral so delivered, and the Lender shall thereafter be discharged from any liability therefor. 6.2 Cumulative Security. The execution and delivery of this Security Agreement in no manner shall impair or affect any other security (by endorsement or otherwise) for the payment of the Obligations. No security taken hereafter as security for payment of all or any portion of the Obligations shall impair in any manner or affect this Security Agreement. All such present and future additional security is to be considered as cumulative security. 6.3 Continuing Agreement. This is a continuing agreement and the conveyance hereunder shall remain in full force and effect and all the rights, powers, and remedies of the Lender hereunder shall continue to exist until the Obligations shall be paid in full as the same become due and payable, the Commitment has terminated, and the Lender, upon request of the Pledgor, has executed a written termination statement, reassigned to the Pledgor, without recourse, the Collateral and all rights and liens conveyed hereby and returned possession of the Collateral to the Pledgor. Furthermore, it is contemplated by the parties hereto that there may be times when no Obligations shall be owing. Notwithstanding such occurrences, this Security Agreement shall remain valid and shall be in full force and effect as to subsequent Obligations provided that the Lender has not executed a written termination statement and returned possession of the Collateral to the Pledgor. Otherwise, this Security Agreement shall continue irrespective of the fact that the liability of the Corporation or any Other Liable Party may have ceased and notwithstanding the death or incapacity of the Pledgor or any Other Liable Party or any other event or proceeding affecting the Corporation, the Pledgor, and/or any Other Liable Party. 6.4 Cumulative Rights. The rights, powers, and remedies of the Lender hereunder shall be in addition to all rights, powers, and remedies given by statute or rule of law and are cumulative. The exercise of any one or more of the rights, powers, and remedies provided herein shall not be construed as a waiver of any other rights, powers, and remedies of the Lender. The Lender shall have the rights, powers, and remedies of a secured party under the Texas Business and Commerce Code, as amended. 6.5 Exercise of Rights. Time shall be of the essence for the performance of any act under this Security Agreement by the Pledgor, but neither the Lender's acceptance of partial or delinquent payments nor any forbearance, failure, or delay by the Lender in exercising any right, power or remedy shall be deemed a waiver of any obligation of the Pledgor, the Corporation, or any Other Liable Party or of any right, power, or remedy of the Lender or preclude any other or further exercise thereof; and no single or partial exercise of any right, power, or remedy shall preclude any other or further exercise thereof or the exercise of any other right, power, or remedy. 6.6 Remedy and Waiver. The Lender may remedy or waive any default without waiving the default remedied or waiving any prior or subsequent default. 6.7 Non-Judicial Remedies. The Lender may enforce its rights hereunder without prior judicial process or judicial hearing. The Pledgor expressly waives, renounces, and knowingly relinquishes any and all legal rights which might otherwise require the Lender to enforce its rights by judicial process. In so providing for non-judicial remedies, the Pledgor recognizes and concedes that such remedies are consistent with the usage of the trade, are responsive to commercial necessity and are the result of bargain at arm's length. Nothing herein is intended to prevent the Lender or the Pledgor from resorting to judicial process at such party's option. 6.8 Preservation of Liability. Neither this Security Agreement nor the exercise by the Lender of (or the failure to so exercise) any right, power, or remedy conferred herein or by law shall be construed as relieving the Pledgor or any Other Liable Party from full liability thereon and for any deficiency thereon. 6.9 Notices and Other Communications. Except as to verbal notices expressly authorized herein, which verbal notices shall be confirmed in writing, all notices, requests, and communications hereunder shall be in writing (including by telecopy). Unless otherwise expressly provided herein, any such notice, request, demand, or other communication shall be deemed to have been duly given or made when delivered by hand, or, in the case of delivery by mail, when deposited in the mail, certified mail, return receipt requested, postage prepaid, or, in the case of telecopy notice, when receipt thereof is acknowledged orally or by written confirmation report, addressed as follows: (a) if to the Lender, to: Bank One, Texas, National Association 910 Travis Houston, Texas 77002 Attention: Energy Group (or for notice by mail, to: P.

This Security Agreement may not be amended nor may any of its terms be waived except in writing duly signed by the party against whom enforcement of the amendment or waiver is sought. 6.12 Invalidity. If any provision of this Security Agreement is rendered or declared illegal, invalid, or unenforceable by reason of any existing or subsequently enacted legislation or by a judicial decision that has become final, the Pledgor and the Lender shall promptly meet and negotiate substitute provisions for those rendered illegal, invalid, or unenforceable, but all of the remaining provisions shall remain in full force and effect. 6.13 GOVERNING LAW. THIS SECURITY AGREEMENT SHALL BE DEEMED TO BE A CONTRACT MADE UNDER AND SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF TEXAS WITHOUT GIVING EFFECT TO PRINCIPLES THEREOF RELATING TO CONFLICTS OF LAW, PROVIDED, HOWEVER, THAT VERNON'S TEXAS CIVIL STATUTES, ARTICLE 5069, CHAPTER 15 (WHICH REGULATES CERTAIN REVOLVING CREDIT LOAN ACCOUNTS AND REVOLVING TRI-PARTY ACCOUNTS) SHALL NOT APPLY. 6.14 JURISDICTION AND VENUE.
