(d) Rate Management Transactions. Payment of any and all obligations, contingent or otherwise, whether now existing or hereafter arising, of Borrower or any Subsidiary Guarantor to the Lenders or to any of their Affiliates or successors arising under or in connection with Rate Management Transactions (as hereinafter defined).

Section 3. Representations and Warranties. Each Pledgor hereby represents and warrants to Secured Party that:

(a) Each Pledgor is the legal and equitable owner of the Collateral, has the necessary authority to pledge the Collateral being pledged by it and holds the same free and clear of all liens, charges, encumbrances and security interests of every kind and nature; each Pledgor has good right and legal authority to pledge the Collateral being pledged by it in the manner hereby done or contemplated and will defend its title thereto against the claims of all persons whomsoever.

(b) Except for any required notifications to and actions required by the Secretary of Issuer, if any, required by applicable law, with respect to the pledge of the Pledged Securities provided for in this Pledge Agreement, no consent or approval of any person, governmental body or regulatory authority, or of any securities exchange, was or is necessary to the validity of such pledge.

Section 4. Events of Default. The term "Default" as used herein, shall mean (i) the occurrence of any Event of Default, as that term is defined in the Credit Agreement or (ii) if any representation, warranty or other information provided or delivered by any Pledgor in connection with this Pledge Agreement is determined to be in any respect false or misleading.

Section 5. Remedies Upon Default. Upon the occurrence and during the continuance of a Default:

(a) Secured Party shall be entitled to exercise any and all rights granted to it by the Note, the Credit Agreement, and this Pledge Agreement.

(b) Secured Party shall be entitled to exercise any and all rights and remedies of a secured party under the Uniform Commercial Code of the State of Texas (the "Code"), and any and all rights granted by any other applicable law or statute, including, without limitation, the right to take whatever steps it deems reasonably necessary to preserve the value of the Collateral pledged to it or in which it otherwise has a security interest and to enforce and realize upon such security interest in such Collateral.

(c) Secured Party may, upon notice to each Pledgor (i) without giving notice to any Pledgor, apply, in the manner set forth in Section 6 below, any cash dividends or interest received by it and (ii) if following such application, there shall remain outstanding any obligations, sell the remaining Collateral, or any part thereof, at public or private sale, for cash, upon credit or for future delivery as Secured Party shall deem appropriate. Secured Party shall be authorized at any such sale (if, on the advice of counsel, it deems it advisable to do so) to restrict the prospective bidders or purchasers to persons who will represent and agree that they are purchasing the Collateral for their own account for investment and not with a view to the distribution or sale thereof, and upon consummation of any such sale, Secured Party shall have the right to assign, transfer and deliver to the purchaser or purchasers thereof the Collateral so sold. Each such purchaser at any such sale shall hold the property sold absolutely free from any claim or right on the part of any Pledgor, and each Pledgor hereby waives (to the extent permitted by law) all rights of redemption, stay and/or appraisal that such Pledgor now has or may at any time in the future have, under any rule of law or statute now existing or hereafter enacted.

(d) Secured Party shall give each Pledgor ten (10) days' written notice of Secured Party's intention to make any such public or private sale. Such notice, in case of public sale, shall state the time and place for such sale, and, in the case of private sale, the day on which the Collateral, or any portion thereof, will first be offered for sale. Any such public sale shall be held at such time or times within the ordinary business hours and at such place or places as Secured Party may fix and shall state in the notice of such sale. At any sale, the Collateral, or any portion thereof, to be sold may be sold in one lot as an entirety or in separate parcels, as Secured Party may (in its sole and absolute discretion) determine. Secured Party shall not be obligated to make any sale of Collateral if it shall determine not to do so, regardless of the fact that notice of sale of Collateral may have been given. Secured Party may, without notice or publication, adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for sale, and such sale may, without further notice, be made at the time and place to which the same was so adjourned. In the event a sale of all or any part of the Collateral is made on credit or for future delivery, the Collateral so sold may be retained by Secured Party until the sale price is paid by the purchaser or purchasers thereof, but Secured Party shall not incur any liability in case any such purchaser or purchasers shall fail to take up and pay for the Collateral so sold and, in case of any such failure, such Collateral may be sold again upon like notice. As an alternative to exercising the power of sale herein conferred upon it, Secured Party may proceed by a suit or suits at law or in equity to foreclose under this Pledge Agreement and to sell the Collateral, or any portion thereof, pursuant to a judgment or decree of a court or courts of competent jurisdiction.

(e) Secured Party may at its option retain the Collateral in satisfaction of the obligations whenever the circumstances are such that Secured Party is entitled to do so under the Code.

(f) Secured Party may at its option perform or attempt to perform (but Secured Party shall not be obligated to do so) any of Pledgors' covenants, duties, liabilities, obligations, or agreements hereunder or under the Note, the Credit Agreement, and/or this Pledge Agreement, and any

amount expended by Secured Party in such performance or attempted performance shall become a part of the obligations, and each Pledgor agrees to promptly pay any such amount to Secured Party.

In order to facilitate Secured Party's enforcing its rights and remedies with respect to the Collateral and in order to allow Secured Party to preserve the property or interest in property evidenced by the certificate(s) representing the Collateral, Secured Party may cause the Pledged Securities or any other Collateral to be transferred to its own name and it may take such actions as are deemed reasonably necessary by it, and each Pledgor will take whatever actions and execute whatever documents are deemed reasonably necessary by Secured Party, to register any such transfer and to cause any and all governmental agencies, if any, having jurisdiction to consent to and approve such transfer.

Secured Party shall not be liable for any action taken in good faith or believed in good faith to be within the power, authority and discretion given to Secured Party hereunder in the Credit Agreement or in the Note, and each Pledgor does hereby agree that any action so taken by Secured Party shall not be considered as an impairment of the Collateral.

No waiver by Secured Party of any Default shall operate as a waiver of any other Default or of the same Default on a future occasion, and no failure or delay by Secured Party in exercising any right, power, or privilege hereunder shall operate as a waiver thereof, and no single or partial exercise thereof shall preclude any other or further exercise or the exercise of any other right, power or privilege.

Section 6. Application of Proceeds of Sale and Cash. The proceeds of any sale of Collateral sold pursuant to Section 5 hereof and any cash included in the Collateral shall be applied by Secured Party as follows:

First: to the payment of all costs and expenses incurred by Secured Party in connection with such sale, including, but not limited to, all court costs and the reasonable fees and expenses of counsel for Secured Party in connection therewith, and to the repayment of all advances made by Secured Party hereunder for the account of any Pledgor and the payment of all costs and expenses paid or incurred by Secured Party upon the exercise of any right or remedy hereunder or thereunder, to the extent that such advances, costs and expenses shall not have been paid to Secured Party upon its demand therefor;

Second: to the payment in full of the obligations secured hereby, to the extent not previously paid by any Pledgor with any amounts in payment applied first to interest, then to principal; and

Third: to the payment to each Pledgor of any remainder of such proceeds.

Section 7. Reimbursement of Secured Party. Each Pledgor hereby agrees to reimburse Secured Party on demand for all expenses incurred by it in connection with the administration and enforcement of this Pledge Agreement, and agrees to indemnify Secured Party and hold it harmless from and against any and all liability incurred by it hereunder or in connection herewith unless caused by the gross negligence or willful misconduct of Secured Party or any of the Lenders or of its or their employees, agents or representatives.

Section 8. Authority of Secured Party; Financing Statements. Secured Party shall have and be entitled to exercise all such powers hereunder as are specifically delegated to Secured Party by the terms hereof, together with such powers as are reasonably incidental thereto. Secured Party may execute any of its duties hereunder by or through agents or employees and shall be entitled to retain counsel and to act in reliance upon the advice of such counsel concerning all matters pertaining to its duties hereunder. Each Pledgor hereby authorizes the Secured Party to file, and if requested will execute and deliver to the Secured Party, all financing statements and other documents and take such other actions as may from time to time be requested by the Secured Party in order to maintain a first perfected

security interest in and, if applicable, Control of, the Collateral. Each Pledgor will take any and all actions necessary to defend title to the Collateral against all persons and to defend the security interest of the Secured Party in the Collateral and the priority thereof against any Lien not expressly permitted hereunder. "Control" shall have the meaning set forth in Article 8, or, if applicable, in Section 9-104, 9-105, 9-106 or 9-107 of Article 9 of the Code as in effect from time to time.

Section 9. Secured Party Appointed Attorney-in-Fact. Each Pledgor hereby appoints Secured Party as such Pledgor's attorney-in-fact for the purpose of carrying out the provisions of this Pledge Agreement and taking any action and executing any instrument which it may deem necessary or advisable to accomplish the purposes hereof, which appointment is irrevocable and coupled with an interest. Without limiting the generality of the foregoing, Secured Party shall have the right and power at any time while a Default exists to receive, endorse and collect all checks and other orders for the payment of money made payable to any Pledgor representing any interest or dividend or other distribution or amount payable in respect of the Pledged Securities or other Collateral or any part thereof and to give full discharge for the same.

Section 10. Voting Rights, Dividends, Etc.

(a) Except upon occurrence and during the continuance of any Default hereunder, each Pledgor shall have the right to vote any of the Collateral on any matter presented for approval to the security holders of the issuer(s) of the Pledged Securities or other Collateral.

(b) Any and all stock or liquidating dividends, other distributions in property, return of capital or other distributions made on or in respect of any of the Collateral, whether resulting from a subdivision, combination or reclassification of the outstanding capital stock of the issuer(s) thereof or received in exchange for or upon conversion of the Collateral, or any part thereof, or as a result of any merger, consolidation, acquisition or other exchange of assets to which the issuer(s) thereof may be a party or otherwise, shall be and become part of the Collateral pledged hereunder and, if received by any Pledgor, shall forthwith be delivered to Secured Party to be held by it as Collateral hereunder and shall be applied in accordance with the provisions hereof.

(c) Except upon the occurrence and during the continuance of any Default hereunder, each Pledgor shall have the sole and exclusive right to receive and retain the dividends and interest payable or accruing from any of the Collateral, and to retain all other rights and benefits from the Collateral.

Section 11. Covenants With Respect to Collateral. Each Pledgor agrees with Secured Party with respect to the Collateral as follows:

(a) Each Pledgor hereby transfers all interests in any general partnership, limited partnership, limited liability partnership or other partnership including, without limitation, all partnership interests of Operating and the certificates, if any, representing such partnership interests and any interest of each Pledgor on the books and records of such partnership or on the books and records of any securities intermediary pertaining to such interest and all dividends, distributions, cash, warrants, rights, options, instruments, securities and other property or proceeds from time to time received, receivable or otherwise distributed in respect of or in exchange for any or all of such partnership interests to Secured Party. Each Pledgor covenants that with respect to any additional partnership interests issued to or received by such Pledgor (i) that is represented by a certificate or that is an "instrument", it shall cause such certificate or instrument to be delivered to the Agent, indorsed in blank by an "effective indorsement" (as defined in Section 8-107 of the Code), regardless of whether such certificate constitutes a "certificated security" for purposes of the Code and (ii) that is an "uncertificated security" for purposes of the Code, it shall cause the issuer of such uncertificated security to either (x) register the Agent as the registered owner thereof on the books and records of the issuer or (y) execute an agreement substantially in the form of Exhibit A

hereto, pursuant to which such issuer agrees to comply with the Agent's instructions with respect to such uncertificated security without further consent by such Issuer.

(b) From and after the date hereof, each Pledgor (i) shall not and shall not attempt to encumber, subject to any further pledge or security interest, sell, transfer or otherwise dispose of any of the Collateral or any interest therein; (ii) shall not permit or suffer any of the Collateral to be attached or levied upon or seized in any legal proceedings, or held by virtue of any lien or distress; and (iii) shall pay promptly all taxes and assessments upon any of the Collateral.

Section 12. Termination.

Any such reassignment shall be without recourse upon or warranty by Secured Party and at the expense of such Pledgor.

Section 13. Binding Agreement, Assignment.

Section 14. Interest Charges Not Permitted by Law. No provision of this Pledge Agreement or of the Note or the Credit Agreement shall require the payment or permit the collection of interest in excess of the maximum permitted by law. If any interest in excess of the maximum permitted by law is provided for in this Pledge Agreement or in the Note or in the Credit Agreement or shall be adjudicated to be so provided, then neither Pledgor nor its successors or assigns shall be obligated to pay such interest in excess of the amount permitted by law, and the right to demand the payment of any such excess shall be and hereby is waived and this provision shall control any other provision of this Pledge Agreement or of the Note or of the Credit Agreement.
