Item 1.01 Entry into a Material Definitive Agreement

On December 6, 2004, AREP Oil & Gas LLC, a Delaware limited liability company (“AREP Oil & Gas”), which is an indirect subsidiary of American Real Estate Partners, L.P. (“AREP”), pursuant to a purchase agreement and related assignment and assumption agreement, each dated as of that date, with Thornwood Associates LP, a Delaware limited partnership (“Thornwood”), purchased $27.5 million aggregate principal amount of term notes issued by TransTexas Gas Corporation (“TransTexas Notes”). The purchase price for the TransTexas Notes was $28,245,890.41, which equals the principal amount of the TransTexas Notes plus accrued but unpaid interest. The notes are payable annually in equal consecutive annual payments of $5,000,000, with the final installment of the unpaid principal payable on August 28, 2008. Interest is payable semi-annually on February 28 and August 28, at the rate of 12% per annum. The TransTexas Notes are secured by a first priority lien on all of TransTexas’ assets. Thornwood and TransTexas each is indirectly controlled by Carl C. Icahn.

On December 6, 2004, AREP Oil & Gas, pursuant to a membership interest purchase agreement and related assignment and assumption agreement, each dated as of that date, by and among AREP Oil & Gas, as purchaser, and Arnos Corp., High River Limited Partnership and Hopper Investments LLC, as sellers, purchased all of the membership interests of Mid River LLC, a Delaware limited liability company (“Mid River”) for an aggregate purchase price of $38,125,998.63. The assets of Mid River consist of $38 million principal amount of term loans (the “Panaco Debt”) outstanding under the term loan and security agreement, dated as of November 16, 2004, among Panaco, Inc. as borrower, the lenders (as defined therein) and Mid River, as administrative agent. The purchase price for the membership interests in Mid River equals the outstanding principal amount of the Panaco Debt, plus accrued but unpaid interest. The principal is payable in 27 equal quarterly installments of $1,357,142.86 commencing on March 15, 2005, through and including September 15, 2011. Interest is payable quarterly at a rate per annum equal to the LIBOR daily floating rate plus four percent. The term loan is secured by first priority liens on all of Panaco’s assets. Each of the sellers and Panaco is indirectly controlled by Mr. Icahn.

Mr. Icahn indirectly owns approximately 86.5% of AREP’s limited partnership depositary and preferred units and indirectly owns 100% of AREP’s general partner, American Property Investors, Inc. Each of the purchases described above was separately approved by the Audit Committee of AREP’s general partner. The Audit Committee was advised as to each transaction by independent legal counsel and financial advisors. The Audit Committee obtained fairness opinions which opined that, as of the date of each transaction, the consideration to be paid by AREP Oil & Gas was fair from a financial point of view to AREP.

ARTICLE VI INDEMNIFICATION 6.1 Indemnification by Seller. Seller agrees to indemnify Purchaser, its Affiliates and their respective officers, directors, employees independent contractors, stockholders, principals, partners, agents, or representatives (each an "Indemnified Person" and collectively, the "Indemnified Persons") against, and to hold each Indemnified Person harmless from, any and all Losses incurred or suffered by any Indemnified Person relating to or arising out of or in connection with (a) any breach of or any inaccuracy in any representation or warranty made by Seller in this Agreement, or (b) any breach of or failure by any Seller to perform any of its covenants or obligations set out or contemplated in this Agreement. 6.2 Claims. As promptly as is reasonably practicable after becoming aware of a claim for indemnification under this Agreement, the Indemnified Person shall promptly give notice to the Seller ("Indemnifying Person") of such claim and the amount the Indemnified Person will be entitled to receive hereunder from the Indemnifying Person; provided that the failure of the Indemnified Person to promptly give notice shall not relieve the Indemnifying Person of its obligations except to the extent (if any) that the Indemnifying Person shall have been prejudiced thereby. If the Indemnifying Person does not object in writing to such indemnification claim within 30 days of receiving notice thereof, the Indemnified Person shall be entitled to recover, on the thirty-fifth day after such notice was given, from the Indemnifying Person the amount of such claim, and no later objection by the Indemnifying Person shall be permitted; if the Indemnifying Person agrees that it has an indemnification obligation but objects that it is obligated to pay only a lesser amount, the Indemnified Person shall nevertheless be entitled to recover, on the thirty- fifth day after such notice was given, from the Indemnifying Person the lesser amount, without prejudice to the Indemnified Person's claim for the difference. In addition to the amounts recoverable by the Indemnified Person from the Indemnifying Person pursuant to the foregoing provisions, the Indemnified Person shall also be entitled to recover from the Indemnifying Person interest on such amounts at the rate of Two Times Prime from, and including, the thirty- fifth day after such notice of an indemnification claim is given to, but not including, the date such recovery is actually made by the Indemnified Person. 11

6.3 Notice of Third Party Claims; Assumption of Defense. The Indemnified Person shall give notice as promptly as is reasonably practicable to the Indemnifying Person of the assertion of any claim, or the commencement of any suit, action or proceeding, by any Person not a party hereto (a "Third Party Claim") in respect of which indemnity may be sought under this Agreement; provided that the failure of the Indemnified Person to promptly give notice shall not relieve the Indemnifying Person of its obligations except to the extent (if any) that the Indemnifying Person shall have been prejudiced thereby. The Indemnifying Person may, at its own expense, participate in the defense of any Third Party Claim, suit, action or proceeding (a) upon notice to the Indemnified Person and (b) upon delivery by the Indemnifying Person to the Indemnified Person a written agreement that the Indemnified Person is entitled to indemnification for all Losses arising out of such Third Party Claim, suit, action or proceeding and that the Indemnifying Person shall be liable for the entire amount of any Loss, at any time during the course of any such Third Party Claim, suit, action or proceeding, assume the defense thereof; provided, however, that (i) the Indemnifying Person's counsel is reasonably satisfactory to the Indemnified Person, and (ii) the Indemnifying Person shall thereafter consult with the Indemnified Person upon the Indemnified Person's reasonable request for such consultation from time to time with respect to such Third Party Claim, suit, action or proceeding. If the Indemnifying Person assumes such defense, the Indemnified Person shall have the right (but not the duty) to participate in the defense thereof and to employ counsel, at its own expense, separate from the counsel employed by the Indemnifying Person. If, however, the Indemnified Person reasonably determines in its judgment that representation by the Indemnifying Person's counsel of both the Indemnifying Person and the Indemnified Person would present such counsel with a conflict of interest, then such Indemnified Person may employ separate counsel to represent or defend it in any such Third Party Claim, action, suit or proceeding and the Indemnifying Person shall pay all of the fees and disbursements in connection with the retention of such separate counsel. If the Indemnifying Person fails to promptly notify the Indemnified Party that the Indemnifying Party desires to defend the Third Party Claim pursuant, or if the Indemnifying Person gives such notice but fails to prosecute vigorously and diligently or settle the Third Party Claim, then the Indemnified Party will have the right to defend, at the sole cost and expense of the Indemnifying Person, the Third Party Claim by all appropriate proceedings, which proceedings will be prosecuted by the Indemnifying Person in good faith or will be settled at the discretion of the Indemnifying Person (with the consent of the Indemnifying Person, which consent will not be unreasonably withheld). The Indemnifying Person will have full control of such defense and proceedings, including any compromise or settlement thereof. Whether or not the Indemnifying Person chooses to defend or prosecute any such Third Party Claim, suit, action or proceeding, all of the parties hereto shall cooperate in the defense or prosecution thereof. 6.4 Settlement or Compromise. Any settlement or compromise made or caused to be made by the Indemnified Person or the Indemnifying Person, of any claim, suit, action or proceeding shall also be binding upon the Indemnifying Person or the Indemnified Person, as the case may be, in the same manner as if a final judgment or decree had been entered by a court of competent jurisdiction in the amount of such settlement or compromise thereof; provided, however, that no obligation, restriction or Loss shall be imposed on the Indemnified Person as a result of such settlement without its prior written consent. The Indemnified Person will give the Indemnifying Person at least 30 days' notice of any proposed settlement or compromise of any Third Party Claim, suit, action or proceeding it is defending, during which time the Indemnifying Person may reject such proposed settlement or compromise; provided, however, that from and 12

after such rejection, the Indemnifying Person shall be obligated to assume the defense of and full and complete liability and responsibility for such Third Party Claim, suit, action or proceeding and any and all Losses in connection therewith in excess of the amount of unindemnifiable Losses which the Indemnified Person would have been obligated to pay under the proposed settlement or compromise. 6.5 Failure of Indemnifying Person to Act. In the event that the Indemnifying Person does not assume the defense of any Third Party Claim, suit, action or proceeding brought against an Indemnified Person, then any failure of the Indemnified Person to defend or to participate in the defense of any such Third Party Claim, suit, action or proceeding or to cause the same to be done, shall not relieve the Indemnifying Person of any of its obligations under this Agreement. 6.6 Tax Character.

Sellers agree jointly and severally to indemnify Purchaser, its Affiliates and their respective officers, directors, employees independent contractors, stockholders, principals, partners, agents, or representatives (each an "Indemnified Person" and collectively, the "Indemnified Persons") against, and to hold each Indemnified Person harmless from, any and all Losses incurred or suffered by any Indemnified Person relating to or arising out of or in connection with (a) any breach of or any inaccuracy in any representation or warranty made by Sellers in this Agreement, or (b) any breach of or failure by any Sellers to perform any of its covenants or obligations set out or contemplated in this Agreement. 6.2 Claims. As promptly as is reasonably practicable after becoming aware of a claim for indemnification under this Agreement, the Indemnified Person shall promptly give notice to the indemnifying Seller or Sellers ("Indemnifying Person") of such claim and the amount the Indemnified Person will be entitled to receive hereunder from the Indemnifying Person; provided that the failure of the Indemnified Person to promptly give notice shall not relieve the Indemnifying Person of its obligations except to the extent (if any) that the Indemnifying Person 6

shall have been prejudiced thereby. If the Indemnifying Person does not object in writing to such indemnification claim within 30 days of receiving notice thereof, the Indemnified Person shall be entitled to recover, on the thirty-fifth day after such notice was given, from the Indemnifying Person the amount of such claim, and no later objection by the Indemnifying Person shall be permitted; if the Indemnifying Person agrees that it has an indemnification obligation but objects that it is obligated to pay only a lesser amount, the Indemnified Person shall nevertheless be entitled to recover, on the thirty-fifth day after such notice was given, from the Indemnifying Person the lesser amount, without prejudice to the Indemnified Person's claim for the difference. In addition to the amounts recoverable by the Indemnified Person from the Indemnifying Person pursuant to the foregoing provisions, the Indemnified Person shall also be entitled to recover from the Indemnifying Person interest on such amounts at the rate of Two Times Prime from, and including, the thirty-fifth day after such notice of an indemnification claim is given to, but not including, the date such recovery is actually made by the Indemnified Person. 6.3 Notice of Third Party Claims; Assumption of Defense. The Indemnified Person shall give notice as promptly as is reasonably practicable to the Indemnifying Person of the assertion of any claim, or the commencement of any suit, action or proceeding, by any Person not a party hereto (a "Third Party Claim") in respect of which indemnity may be sought under this Agreement; provided that the failure of the Indemnified Person to promptly give notice shall not relieve the Indemnifying Person of its obligations except to the extent (if any) that the Indemnifying Person shall have been prejudiced thereby. The Indemnifying Person may, at its own expense, participate in the defense of any Third Party Claim, suit, action or proceeding (a) upon notice to the Indemnified Person and (b) upon delivery by the Indemnifying Person to the Indemnified Person a written agreement that the Indemnified Person is entitled to indemnification for all Losses arising out of such Third Party Claim, suit, action or proceeding and that the Indemnifying Person shall be liable for the entire amount of any Loss, at any time during the course of any such Third Party Claim, suit, action or proceeding, assume the defense thereof; provided, however, that (i) the Indemnifying Person's counsel is reasonably satisfactory to the Indemnified Person, and (ii) the Indemnifying Person shall thereafter consult with the Indemnified Person upon the Indemnified Person's reasonable request for such consultation from time to time with respect to such Third Party Claim, suit, action or proceeding. If the Indemnifying Person assumes such defense, the Indemnified Person shall have the right (but not the duty) to participate in the defense thereof and to employ counsel, at its own expense, separate from the counsel employed by the Indemnifying Person. If, however, the Indemnified Person reasonably determines in its judgment that representation by the Indemnifying Person's counsel of both the Indemnifying Person and the Indemnified Person would present such counsel with a conflict of interest, then such Indemnified Person may employ separate counsel to represent or defend it in any such Third Party Claim, action, suit or proceeding and the Indemnifying Person shall pay all of the fees and disbursements in connection with the retention of such separate counsel. If the Indemnifying Person fails to promptly notify the Indemnified Party that the Indemnifying Party desires to defend the Third Party Claim pursuant, or if the Indemnifying Person gives such notice but fails to prosecute vigorously and diligently or settle the Third Party Claim, then the Indemnified Party will have the right to defend, at the sole cost and expense of the Indemnifying Person, the Third Party Claim by all appropriate proceedings, which proceedings will be prosecuted by the Indemnifying Person in good faith or will be settled at the discretion of the Indemnifying Person (with the consent of the Indemnifying Person, which consent will not be unreasonably withheld). The Indemnifying Person will have full control of 7

such defense and proceedings, including any compromise or settlement thereof. Whether or not the Indemnifying Person chooses to defend or prosecute any such Third Party Claim, suit, action or proceeding, all of the parties hereto shall cooperate in the defense or prosecution thereof. 6.4 Settlement or Compromise. Any settlement or compromise made or caused to be made by the Indemnified Person or the Indemnifying Person, of any claim, suit, action or proceeding shall also be binding upon the Indemnifying Person or the Indemnified Person, as the case may be, in the same manner as if a final judgment or decree had been entered by a court of competent jurisdiction in the amount of such settlement or compromise thereof; provided, however, that no obligation, restriction or Loss shall be imposed on the Indemnified Person as a result of such settlement without its prior written consent. The Indemnified Person will give the Indemnifying Person at least 30 days' notice of any proposed settlement or compromise of any Third Party Claim, suit, action or proceeding it is defending, during which time the Indemnifying Person may reject such proposed settlement or compromise; provided, however, that from and after such rejection, the Indemnifying Person shall be obligated to assume the defense of and full and complete liability and responsibility for such Third Party Claim, suit, action or proceeding and any and all Losses in connection therewith in excess of the amount of unindemnifiable Losses which the Indemnified Person would have been obligated to pay under the proposed settlement or compromise. 6.5 Failure of Indemnifying Person to Act. In the event that the Indemnifying Person does not assume the defense of any Third Party Claim, suit, action or proceeding brought against an Indemnified Person, then any failure of the Indemnified Person to defend or to participate in the defense of any such Third Party Claim, suit, action or proceeding or to cause the same to be done, shall not relieve the Indemnifying Person of any of its obligations under this Agreement. 6.6 Tax Character.

AMENDED AND RESTATED OIL & GAS LOAN AGREEMENT ("RESTRUCTURED O&G AGREEMENT") TRANSTEXAS GAS CORPORATION, a corporation organized under the laws of the State of Delaware ("Borrower"), GALVESTON BAY PIPELINE COMPANY, a subsidiary of Borrower ("GB Pipeline), GALVESTON BAY PROCESSING CORPORATION, a subsidiary of Borrower "GB Processing" and together with GB Pipeline and any other subsidiary of Borrower, which shall become a party hereto, the "Guarantors") and THORNWOOD ASSOCIATES LP ("Lender") are hereby restating and amending the Oil and Gas Revolving Credit and Term Loan Agreement with certain "Lenders" (as defined therein) and GMAC Commercial Credit LLC , a limited liability company organized under the laws of the State of New York, as agent for the Lenders, dated as of March 15, 2000 the "Original Agreement" and as restated and amended on this 28 day of August, 2003, the "Restructured O&G Agreement" or the "Agreement"). This Agreement shall become valid and enforceable only when, and if, Creditor's Joint Plan of Reorganization for Debtors Under Chapter 11 of the Bankruptcy Code Submitted by Thornwood Associates LP, dated as of June 27, 2003, as modified July 8, 2003 and as may be modified thereafter ("Thornwood's Plan" or the "Plan"), confirmed by Order of the Bankruptcy Court, dated August 28, 2003, becomes effective. Pursuant to the Plan, as of the date hereof, each holder of an Allowed Prepetition O&G Claim, in full satisfaction, settlement, release and discharge of, and exchange for, such Claim received (i) Cash in a sum equal to its pro rata share of the Allowed O&G Claim less $32.5 million and (ii) its pro rata share of the Restructured O&G Note in principal amount of $32.5 million, and Thornwood paid to the Prepetition O&G Lenders pro rata the Cash set forth in paragraph (i) hereto and an amount equal to the principal amount of the Restructured O&G Note. Subject to such payment and pursuant to the terms of the Plan, the Reorganized Debtors are issuing the Restructured O&G Note directly to Thornwood, and are entering into this Restructured O&G Agreement and the Restructured O&G Security Agreement directly with Thornwood. NOW, THEREFORE, in consideration of the mutual covenants and undertakings herein contained, Borrower and Lender hereby agree as follows: I. DEFINITIONS. Any term not defined in this Agreement shall have the meaning ascribed to it in the Plan. The following additional terms shall mean as follows: 1.1. GENERAL TERMS For purposes of this Agreement the following terms shall have the following meanings: "Accounts" means "accounts," as that term is defined in Article 9 of the Uniform Commercial Code as in effect in the State of New York, together with the proceeds and products thereof. "Adjusted Consolidated Tangible Assets" means (without duplication), as of the date of determination, (a) the sum of (i) discounted future net cash flows from proved oil and gas reserves of Borrower and its Subsidiaries, (before any state or federal income tax), as estimated in a Proved Reserve Report as of a date no earlier than Borrower's most recent fiscal year end

(or, if such Proved Reserve Report is unavailable, or if the date of determination is after the end of the first fiscal quarter of the most recent fiscal year of Borrower, as estimated by Borrower's engineers on the same basis as of a date no earlier than the end of the most recent fiscal quarter, which estimates shall be confirmed in writing by a report by nationally recognized independent petroleum engineers in the event of a Material Change), (ii) the Net Working Capital of Borrower on a date no earlier than the date of Borrower's latest consolidated annual or quarterly financial statements, and (iii) with respect to all other tangible assets (which are deemed to include mineral lease-hold interests) of Borrower and its Subsidiaries, the net book value of such other tangible assets on a date no earlier than the date of Borrower's latest consolidated annual or quarterly financial statements, minus (b) minority interests and, to the extent not otherwise taken into account in determining Adjusted Consolidated Tangible Assets, any gas balancing liabilities of Borrower and its Subsidiaries. In addition to, but without duplication of the foregoing, for purposes of this definition, "Adjusted Consolidated Tangible Assets" shall be calculated after giving effect, on a pro forma basis, to (1) any Permitted Investment, on or before the date of the transaction giving rise to the need to calculate Adjusted Consolidated Tangible Assets (the "Assets Transaction Date"), in any other Person that, as a result of such investment, becomes a Subsidiary of Borrower, (2) the acquisition, on or before the Assets Transaction Date (by merger, consolidation, or purchase of stock or assets), of any business or assets, including, without limitation, Permitted Investments, and (3) any sales or other dispositions of assets (other than sales of Inventory Hydrocarbons or other mineral products in the ordinary course of business) occurring on or prior to the Assets Transaction Date. For purposes of calculating the ratio of Borrower's Adjusted Consolidated Tangible Assets to total consolidated Debt of Borrower and its Subsidiaries, Debt of a Subsidiary that is not a wholly-owned Subsidiary of Borrower (which Debt is non-recourse to Borrower or any of its other Subsidiaries or any of their assets) shall be included only to the extent of Borrower's pro rata ownership interest in such Subsidiary. "Adjusted Net Assets" of a Guarantor means the lesser of (a) the amount by which the Guarantor's property, at a fair valuation, exceeds the sum of its debts (including unliquidated or contingent debts), (b) the amount by which the present fair salable value of the Guarantor's assets exceeds the amount that will be required to pay its probable liability on its existing debts as they become absolute and matured, (c) the amount by which the Guarantor's assets exceed the maximum amount that would constitute unreasonably small capital for its business, or (d) the amount by which the Guarantor's assets exceed the amount that such Guarantor should reasonably retain to pay its debts (including unliquidated or contingent debts) as they mature. "Affiliate" means, with respect to any specified Person, (a) any other Person directly or indirectly controlling or controlled by, or under direct or indirect common control with, such specified Person, or (b) any director or controlling shareholder of such other Person or (c) any officer of such specified Person or such other Person. For purposes of this definition, the term "control" means (i) the power to direct the management and policies of a Person, directly or through one or more intermediaries, whether through the ownership of voting securities, by contract, or otherwise, or (ii) without limiting the foregoing, the beneficial ownership of 10% or more of the voting power of the voting common equity of such Person (on a fully diluted basis) or of warrants or other rights to acquire such equity (regardless of whether presently exercisable). - 2 -

"Ancillary Documents" means the Security Documents, the Note and any and all other agreements, instruments and documents, including, without limitation, guaranties, pledges, powers of attorney, consents, and all other writings heretofore, now or hereafter executed by Borrower or any Subsidiary and delivered to Lender in respect of the transactions contemplated by this Agreement. "Asset Sale" means any direct or indirect conveyance, sale, transfer or other disposition, in one transaction or a series of related transactions, of any of the properties, businesses or assets of Borrower or any Subsidiary of Borrower, whether owned on the Effective Date or thereafter acquired; provided, however, that "Asset Sale" shall not include (a) any disposition of Inventory in the ordinary course of business, (b) any pledge or disposition of assets (if such pledge or disposition would otherwise constitute an Asset Sale) to the extent and only to the extent that it results in the creation of a Permitted Lien (other than the creation of a Permitted Lien in connection with a Drilling Production Payment or a Drilling Program, which in either case shall be treated as an Asset Sale hereunder), or (c) any issuance or disposition of securities that is made pursuant to and in accordance with the Plan or a Plan Order. "Attributable Debt" in respect of a Sale and Leaseback Transaction means, at the time of determination, the present value (discounted at the rate of interest implicit in such transaction, determined in accordance with GAAP, or, in the event that such rate of interest is not reasonably determinable, discounted at the rate of interest of 15%) of the obligation of the lessee for net rental payments during the remaining term of the lease included in such Sale and Leaseback Transaction (including any period for which such lease has been extended or may, at the option of the lessor, be extended). "Board of Directors" means, with respect to any Person, the board of directors of such Person or any committee of the board of directors of such Person authorized, with respect to any particular matter, to exercise the power of the board of directors of such Person. "Board Resolution" means, with respect to any Person, a duly adopted resolution of the Board of Directors of such Person. "Borrower" means TransTexas Gas Corporation, a Delaware corporation, and all permitted successors and assigns. "Borrower Entities" means Borrower and each of its Subsidiaries. "Business Day" means any day other than a day on which commercial banks in New York are authorized or required by law to close. "Capital Expenditures" of a Person means expenditures (whether paid in cash or accrued as a liability) by such Person or any of its Subsidiaries that, in conformity with GAAP, are or would be included in "capital expenditures," "additions to property, plant, or equipment" or comparable items in the consolidated financial statements of such Person consistent with prior accounting practices. - 3 -

"Capital Lease" as applied to any Person, means any lease of any property (whether real, personal, or mixed) by that Person as lessee which, in conformity with GAAP, is accounted for as a capital lease on the balance sheet of that Person. "Capital Stock" means, with respect to any Person, any capital stock of such Person and shares, interests, or other ownership interests (however designated) of such Person and any rights (other than debt securities convertible into corporate stock), warrants or options to purchase any of the foregoing, including without limitation, each class of common stock and preferred stock of such Person, if such Person is a corporation, and each general or limited partnership interest or other equity interest of such Person, if such Person is a partnership. "Capitalized Lease Obligation" means obligations under a lease that are required to be capitalized for financial reporting purposes in accordance with GAAP, and the amount of Debt represented by such obligations shall be the capitalized amount of such obligations, as determined in accordance with GAAP.

XIII. GUARANTY. 13.1. GUARANTY. Each Guarantor jointly and severally assumes and unconditionally guaranties to Lender the prompt payment when due (whether by acceleration or otherwise) of all present and future Obligations, and irrespective of the genuineness, validity, regularity or enforceability of such Obligations, or of any instrument evidencing any of the Obligations or of any collateral therefor or of the existence or extent of such collateral, and irrespective of the allowability, allowance or disallowance of any or all of the Obligations in any case commenced by or against Borrower under Title 11, United States Code, including, without limitation, post-petition interest, fees, costs and charges that would have accrued or been added to the Obligations but for the commencement of such case. 13.2. NO IMPAIRMENT. Lender may at any time and from time to time, either before or after the maturity thereof, without notice to or further consent of any Guarantor, extend the time of payment of, exchange or surrender any collateral for, renew or extend any of the Obligations or increase or decrease the interest rate thereon, and may also make any agreement with Borrower or with any other party to or person liable on any of the Obligations, or interested therein, for the extension, renewal, payment, compromise, discharge or release thereof, in whole or in part, or for any modification of the terms thereof or of any Ancillary Documents, or make any election of rights Lender may deem desirable under the United States Bankruptcy Code, as amended, or any other federal or state bankruptcy, reorganization, moratorium or insolvency law relating to or affecting the enforcement of creditors' rights generally (any of the foregoing, an "Insolvency Law") without in any way impairing or affecting the obligations of Guarantors hereunder. The obligations of Guarantors hereunder shall be effective regardless of the subsequent incorporation, merger or consolidation of Borrower, or any change in the composition, nature, personnel or location of Borrower and shall extend to any successor entity to Borrower, including a debtor in possession or the like under any Insolvency Law. 13.3.

Each Guarantor hereby knowingly accepts the full range of risk encompassed within a contract of "continuing guaranty" which risk includes the possibility that Borrower will contract additional indebtedness for which such Guarantor may be liable hereunder after Borrower's financial condition or ability to pay its lawful debts when they fall due has deteriorated, whether or not Borrower has properly authorized incurring such additional indebtedness. Each Guarantor acknowledges that (a) no oral representations, including any representations to extend credit or provide other financial accommodations to Borrower, have been made by Lender to induce such Guarantor to enter into this Agreement and (b) any extension of credit to Borrower shall be governed solely by the provisions of this Loan Agreement and the Ancillary Documents.

This is a guaranty of payment and not of collection. Lender shall be under no obligation to institute suit, exercise rights or remedies or take any other action against Borrower or any other person liable with respect to any of the Obligations or resort to any collateral security held by it to secure any of the Obligations as a condition precedent to any Guarantor being obligated to perform as agreed herein and each Guarantor hereby waives any and all rights which it may have by statute or otherwise which would require Lender to do any of the foregoing.

Each Guarantor hereby waives all rights of suretyship. Each Guarantor hereby waives any rights to interpose any defense, counterclaim or offset of any nature and description which it may have or which may exist between and among Lender, Borrower and/or any Guarantor with respect to any Guarantor's obligations hereunder, or which Borrower may assert on the underlying debt, including but not limited to failure of consideration, breach of warranty, fraud, payment (other than cash payment in full of the Obligations), statute of frauds, bankruptcy, infancy, statute of limitations, accord and satisfaction, and usury. (b) Each Guarantor further waives (i) notice of the acceptance of this Agreement, of the making of any such loans or extensions of credit, and of all notices and demands of any kind to which such Guarantor may be entitled, including, without limitation, notice of adverse change in Borrower's financial condition or of any other fact which might materially increase the risk of any Guarantor and (ii) presentment to or demand of payment from - 44 -

anyone whomsoever liable upon any of the Obligations, protest, notices of presentment, non-payment or protest and notice of any sale of collateral security or any default of any sort. 13.5. PAYMENTS FROM GUARANTOR. Lender, with or without notice to any Guarantor, may apply on account of the Obligations any payment from any Guarantor or any other guarantor, or amounts realized from any security for the Obligations. 13.6. NO TERMINATION. This is a continuing irrevocable guaranty and shall remain in full force and effect and be binding upon each Guarantor and each Guarantor's successors and assigns, until all of the Obligations have been paid in full and this Agreement has been terminated.

GUARANTIES OF BORROWER AND MATERIAL SUBSIDIARIES. Borrower and each of its Material Subsidiaries acknowledge, by their execution and delivery of this Agreement and each Guaranty, that Lender is relying on the provisions of this Article XIII, the Security Agreement and the Confirmation Order in extending credit hereunder on the Effective Date, that all Material Subsidiaries of Borrower are benefiting by the financing being provided by Lender and that Lender would not have agreed to provide such financing without the guaranties of all Material Subsidiaries, the Security Agreement and the Confirmation Order.

(d) The Secured Party shall be entitled at any time to file this Agreement, or a carbon, photographic or any other reproduction of this Agreement, as a financing statement, but the failure of the Secured Party to do so shall not impair the validity or enforceability of this Agreement.

(e) In its discretion, the Secured Party may discharge taxes and other encumbrances at any time levied or placed on any of the Collateral, make repairs thereto and pay any necessary filing fees. Each of the Companies agrees to reimburse the Secured Party on demand for any and all reasonable expenditures so made with interest on unpaid amounts at the maximum rate permitted by law. The Secured Party shall have no obligation to any of the Companies to make any such expenditures, nor shall the making thereof relieve any of the Companies of any default. (f) Anything herein to the contrary notwithstanding, each of the Companies shall remain liable under each contract or agreement comprised in the Collateral to be observed or performed by such Companies thereunder. The Secured Party shall not have any obligation or liability under any such contract or agreement by reason of or arising out of this Agreement or the receipt by the Secured Party of any payment relating to any of the Collateral, nor shall the Secured Party be obligated in any manner to perform any of the obligations of any of the Companies under or pursuant to any such contract or agreement, to make inquiry as to the nature or sufficiency of any payment received by the Secured Party in respect of the Collateral or as to the sufficiency of any performance by any party under any such contract or agreement, to present or file any claim, to take any action to enforce any performance or to collect the payment of any amounts which may have been assigned to the Secured Party or to which the Secured Party may be entitled at any time or times other than to account for amounts or Collateral received, and no action taken or omitted shall give rise to any defense, counterclaim or right of action against the Secured Party, unless the Secured Party's actions are taken or omitted to be taken with gross negligence or bad faith or constitute willful misconduct. The Secured Party's sole duty with respect to the custody, safe keeping and physical preservation of the Collateral in its possession, under Section 9-207 of the UCC or otherwise, shall be to deal with such Collateral in the same manner as the Secured Party deals with similar property for its own account. (g) If an Event of Default has occurred and is continuing, the Secured Party may at any time, at its option, transfer to itself or any nominee any securities constituting the Pledged Securities, receive any income thereon and hold such income as additional Collateral or apply it to the Obligations. Regardless of whether any Obligations are due, the Secured Party may demand, sue for, collect, or make any settlement or compromise, which it deems desirable with respect to the Collateral.

After the making of such a request or the giving of any such notification, each of the Companies shall hold any proceeds of collection of chattel paper, general intangibles and instruments received by such Companies as trustee for the Secured Party without commingling the same with other funds of such Companies and shall turn the same over to the Secured Party in the identical form received, together with any necessary endorsements or assignments.

Without limiting the foregoing, in such event the Secured Party may exercise all voting and corporate rights at any meeting of any corporation issuing any such securities and any and all rights of conversion, exchange, subscription or any other rights, privileges or options pertaining to any such securities as if it were the absolute owner thereof, including, without limitation, the rights to exchange at its discretion, any and all such securities upon the merger, consolidation, reorganization, recapitalization or other readjustment of any corporation issuing any such securities or upon the exercise by any such issuer or the Secured Party of any right, privilege or option pertaining to any such securities, and, in connection therewith, to deposit and deliver any and all securities with any committee, depository, transfer agent, registrar or other designated agency upon such terms and conditions as it may determine, all without liability except to account for the property actually received by it, but the Secured Party shall have no duty to exercise any of the aforesaid rights, privileges or options and the Secured Party shall not be responsible for any failure to do so or delay in so doing. Section 7. Default. (a) It shall constitute a Default or an Event of Default under this Agreement if a "Default" or an "Event of Default" shall occur under the Restructured O&G Agreement. (b) If an Event of Default shall have occurred and is continuing and if the Obligations are accelerated under the provisions of the Restructured O&G Agreement, in addition to any other rights and remedies that may be available to the Secured Party under the UCC or the Restructured O&G Agreement or under Section 5 of this Agreement or otherwise under this Agreement or at law, the Secured Party shall also have the following rights and powers: (i) The Secured Party may, without being required to give any notice except as hereinafter provided, sell the Collateral, or any part thereof, at public or private sale, for cash, upon credit or for future delivery and at such price or prices 16

as the Secured Party deems satisfactory, and the Secured Party and/or its collateral agent may be the purchaser of any or all of the Collateral so sold and thereafter hold the same absolutely free from any right or claim of whatsoever kind, and the Obligations or any portion of the Obligations may be applied as a credit against the purchase price. (ii) Upon any such sale, the Secured Party shall have the right to deliver, assign and transfer to the purchaser thereof the Collateral so sold. Each purchaser at any such sale shall hold the property sold absolutely free from any claim or right of whatsoever kind by or on behalf of any of the Companies, including any equity or rights of redemption of any of the Companies, and each of the Companies hereby specifically waives, to the full extent permitted by applicable law, all rights of redemption, stay or appraisal which it has or may have under any rule or law or statute now existing or hereafter adopted. (iii) The Secured Party shall give each of the Companies ten (10) business days' written notice (which each of the Companies agrees is reasonable notification within the meaning of Section 9-611 of the UCC) of its intention to make any such public or private sale. Such notice, in case of public sale, shall state the time and place fixed for such sale and, in case of a private sale, shall state the date after which such sale is to be made. (iv) Any such public sale shall be held at such time or times within ordinary business hours and at such places as the Secured Party may fix in the notices of such sale. At any such sale the Collateral may be sold in one lot as an entirety or in separate parcels, as the Secured Party may, in its sole discretion, determine. (v) The Secured Party shall not be obligated to make any sale of the Collateral of any part thereof if it shall determine not to do so, regardless of the fact that notice of sale of the Collateral may have been given. The 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 the sale, and such sale may, without further notice, be made at any time or place to which the same shall be so adjourned. (vi) In case of any sale of all or any part of the Collateral on credit or for future delivery, the Collateral so sold may be retained by the Secured Party until the selling price is paid by the purchaser thereof, but the Secured Party shall not incur any liability in case of the failure of such purchaser to take up and pay for the Collateral so sold and, in case of any such failure, such Collateral may again be sold upon like notice. (vii) The Secured Party, instead of exercising the power of sale herein conferred upon it, may proceed by a suit or suits at law or in equity to exercise its remedies regarding the Collateral and sell the Collateral, or any portion thereof, under a judgment or decree of a court or courts of competent jurisdiction. 17

(viii) Each of the Companies agrees that if any Event of Default shall have occurred and be continuing, then the Secured Party shall have the right to take possession of the Collateral, and for that purpose the Secured Party may, so far as any of the Companies can give authority therefor, enter upon any premises on which the Collateral may be situated and remove the same therefrom with or without notice or process of law. Each of the Companies waives any and all rights that it may have to a judicial hearing in advance of the enforcement of any of the Secured Party's rights hereunder, including, without limitation, its right following an Event of Default to take immediate possession of the Collateral and to exercise its rights with respect thereto. (ix) If under mandatory requirements of applicable law, the Secured Party shall be required to make disposition of the Collateral within a period of time that does not permit the giving of notice to the Companies as hereinbefore provided, the Secured Party need give each of the Companies only such notice of disposition as shall be reasonably practicable in view of such mandatory requirements of law. (x) The Secured Party may instruct the obligor or obligors on any agreement, instrument or other obligation constituting the Collateral to make any payment or render any performance required by the terms of such agreement, instrument or obligation directly to the Secured Party or its designee. (c) The Secured Party shall incur no liability as a result of the sale of the Collateral, or any part thereof, at any private sale other than for its own gross negligence, willful misconduct or bad faith. Each of the Companies hereby waives, to the maximum extent permitted by applicable law, any claims against the Secured Party arising by reason of the fact that the price at which the Collateral may have been sold at such private sale was less than the price which might have been obtained at a public sale or was less than the aggregate amount of the Obligations, even if the Secured Party accepts the first offer received and does not offer such Collateral to more than one offeree. (d) The Secured Party shall not be obligated to pursue or exhaust its rights and remedies against any particular Collateral or other security for the Obligations before pursuing or enforcing its rights and remedies against any other Collateral or other security for the Obligations. (e) To the extent permitted by law, each of the Companies hereby waives (i) any rights to require the Secured Party to proceed first against any other Person, to exhaust its rights in the Collateral or other security for the Obligations or to pursue any other right that the Secured Party might have, (ii) with respect to the Note, presentment and demand for payment, protest, notice of protest and nonpayment, notice of dishonor, notice of the intention to accelerate and notice of acceleration (except as otherwise set forth in the Restructured O&G Agreement), and (iii) all rights of marshaling in respect of any and all of the Collateral. (f) Without precluding any other methods of sale, each of the Companies acknowledges that the sale of the Collateral shall have been made in a commercially 18

reasonable manner if conducted in conformity with reasonable commercial practices of institutional lenders disposing of similar property. The Secured Party shall not be liable for any depreciation in the value of the Collateral. (g) Each of the Companies agrees that its obligation to deliver the Collateral is of the essence of this Agreement and that accordingly, upon application to a court of equity having jurisdiction, the Secured Party shall be entitled to a decree requiring specific performance by the Companies of such obligation. (h) Remedies of the Secured Party are cumulative and the exercise of any one or more of the remedies provided herein shall not be construed as a waiver of any of the other remedies of the Secured Party. (i) If an Event of Default shall have occurred and be continuing, the proceeds of any sale of or other realization upon all or any part of the Collateral and any other amounts held by the Secured Party under this Agreement shall be applied by the Secured Party as provided in the Restructured O&G Agreement. Any amounts remaining after such applications and the payment in full of the Note with respect to the Obligations shall be remitted to the Companies, its successors or assigns, or as a court of competent jurisdiction may otherwise direct. Section 8. General Provisions. (a) Continuing Security Interest; Binding Effect. This Agreement shall create a continuing security interest in the Collateral and shall (i) remain in full force and effect until termination of the obligations of the Companies under the Restructured O&G Agreement and the indefeasible payment in full thereafter of the Obligations; (ii) be binding upon each of the Companies and its successors and assigns; and (iii) inure to the benefit of the Secured Party and its successors, transferees and assigns. Without limiting the generality of the foregoing clause (iii), the Secured Party may assign or otherwise transfer any of its rights under this Agreement to any other Person, and such Person shall thereupon become vested with all the benefits in respect thereof granted herein or otherwise to the Secured Party. Upon the termination of the obligations of the Secured Party under the Restructured O&G Agreement and the indefeasible payment in full thereafter of the Obligations, each of the Companies shall be entitled to the return, upon its request and at its expense, of such of the Collateral as is in the Secured Party's possession and as shall not have been sold or otherwise disposed of pursuant to the terms hereof. (b) Security Interest Absolute. The lien and security interest created hereunder and the Companies' obligations hereunder and the Secured Party's rights hereunder shall not be released, diminished, impaired or adversely affected by the occurrence of any one or more of the following events: (i) The taking or accepting of any other security or assurance for any or all of the Obligations; 19

(ii) Any release, surrender, exchange, subordination or loss of any security or assurance at any time existing in connection with any or all of the Obligations; (iii) The modification of, amendment to, or waiver of compliance with any terms of the Restructured O&G Agreement or the Note; (iv) Any renewal, extension and/or rearrangement of the payment of any or all of the Obligations or any statement, indulgence, forbearance or compromise that may be granted or given by the Secured Party to any of the Companies or any other Person; (v) any neglect, delay, omission, failure or refusal of the Secured Party to take or prosecute any action in connection with any agreement, document or other instrument evidencing, securing or assuring the payment of any or all of the Obligations; (vi) the illegality, invalidity or unenforceability of all or any part of the Restructured O&G Agreement or the Note; or (vii) any other circumstance (other than payment in full of the Obligations) that might otherwise constitute a defense available to, or a discharge of, the Companies or any party to any document in respect of the Obligations.

The provisions of this Agreement may only be waived by an instrument in writing signed by the Secured Party, and no failure on the part of the Secured Party to exercise, and no delay in exercising, and no course of dealing with respect to, any such right, power or remedy, shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right. No notice to or demand on any of the Companies hereunder shall, of itself, entitle any of the Companies to any other or further notice or demand in the same or similar circumstances. (e) Assignment. Neither this Agreement nor any interest herein or in the Collateral, or any part thereof, may be assigned by any of the Companies without the 20

prior written consent of the Secured Party, except as expressly permitted herein or in the Restructured O&G Agreement. (f) Headings.

(a) Loan Accounts; Noteless Transaction. The Term Loan Principal Debt owed to each Lender shall be evidenced by one or more loan accounts or records maintained by such Lender in the ordinary course of business. The loan accounts or records maintained by Administrative Agent and each Lender shall be prima facie evidence absent manifest error of the amount of the Term Loan made by Borrower from each Lender under this Agreement and the interest and principal payments thereon. Any failure to so record or any error in doing so shall not, however, limit or otherwise affect the obligation of Loan Parties under the Loan Documents to pay any amount owing with respect to the Obligation. (b) Notes. Upon the request of any Lender, made through Administrative Agent, the Principal Debt owed to such Lender may be evidenced by a Term Loan Note. In such event, Borrower shall promptly prepare, execute, and deliver to such Lender such Note payable to the order of such Lender. (c) Payment. All payments of principal, interest, and other amounts to be made by Borrower under this Agreement and the other Loan Documents shall be made to Administrative Agent via the following wiring instructions: Fleet Bank ABA No. 021-200-339 For account of Mid River LLC Account no. 94 293 82 604 in Dollars and in funds which are or will be available for immediate use by Administrative Agent by 1:00 p.m., New York, New York time on the day due, without setoff, deduction, or counterclaim. Payments made after 1:00 p.m., New York, New York time shall be deemed made on the Business Day next following. Administrative Agent shall pay to each Lender any payment of principal, interest, or other amount to which such Lender is entitled hereunder on the same day Administrative Agent shall have received the same from Borrower; provided such payment is received by Administrative Agent prior to 1:00 p.m., New York, New York time, and otherwise before 1:00 p.m., New York, New York time on the Business Day next following. (d) Payment Assumed. Unless Administrative Agent has received notice from Borrower prior to the date on which any payment is due under this Agreement that Borrower will TERM LOAN AND SECURITY AGREEMENT 17

not make that payment in full, Administrative Agent may assume that Borrower has made the full payment due and Administrative Agent may, in reliance upon that assumption, cause to be distributed to the appropriate Lender on that date the amount then due to such Lenders. If and to the extent Borrower does not make the full payment due to Administrative Agent, each Lender shall repay to Administrative Agent on demand the amount distributed to that Lender by Administrative Agent together with interest for each day from the date that Lender received payment from Administrative Agent until the date that Lender repays Administrative Agent (unless such repayment is made on the same day as such distribution), at an annual interest rate equal to the Federal Funds Rate. 3.2 PAYMENTS. The principal of and accrued interest upon the Term Loan Principal Debt shall be due and payable as follows: (a) Interest, computed as stated below, shall be due and payable quarterly as it accrues, commencing March 15, 2005, and thereafter, on the 15th day of each succeeding June, September, December and March, and at maturity; and, (b) Principal shall be due and payable (i) in twenty-seven (27) equal quarterly installments, each in the amount of $1,357,142.86, commencing on March 15, 2005, and thereafter, on the 15th day of each succeeding June, September, December and March, through and including September 15, 2011, and (ii) in one final installment, on December 15, 2011, in the amount of the unpaid principal balance of and accrued unpaid interest upon the Loan as of such date. 3.3 PREPAYMENTS. The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part. All such prepayments shall be made, together with accrued interest to the date of such prepayment on the principal amount prepaid. 3.4 INTEREST ACCRUAL. Except as otherwise provided in this Agreement, the Term Loan Principal Debt bears interest at a rate per annum equal to the lesser of (a) the Wall Street Journal LIBOR Daily Floating Rate plus four percent (4%) and (b) the Maximum Rate. Each change in such per annum rate of interest, subject to the terms of this Agreement, will become effective, without notice to Borrower or any other Person, upon the effective date of such change. 3.5 POST-DEFAULT RATE. At the option of Required Lenders and to the extent permitted by Law, all past-due Term Loan Principal Debt and past due interest accruing on any of the Obligation shall bear interest from maturity (stated or by acceleration) at the Post-Default Rate until paid; provided that, the Post-Default Rate shall automatically apply in the case of SECTION 11.3 where the Post-Default Rate is specified. 3.6 INTEREST RECAPTURE. If the designated rate applicable to any Borrowing exceeds the Maximum Rate, the rate of interest on such Borrowing shall be limited to the Maximum Rate, but any subsequent reductions in such designated rate shall not reduce the rate of interest thereon below the Maximum Rate until the total amount of interest accrued thereon equals the amount of interest which would have accrued thereon if such designated rate had at all times been in effect. In the event that at maturity (stated or by acceleration), or at final payment of the Term Loan Principal Debt, the total amount of interest paid or accrued is less than the amount of interest which would have accrued if such designated rates had at all times been in effect, then, at such time and to the extent permitted by Law, Borrower shall pay an amount equal to the difference between (a) the lesser of the amount of interest which would have accrued if such designated rates had at all times been in effect and the amount of interest which would TERM LOAN AND SECURITY AGREEMENT 18

have accrued if the Maximum Rate had at all times been in effect, and (b) the amount of interest actually paid or accrued on the Term Loan Principal Debt. 3.7 INTEREST CALCULATIONS. Interest will be calculated on the basis of actual number of days (including the first day but excluding the last day) elapsed but computed as if each calendar year consisted of 360 days (unless the calculation would result in an interest rate greater than the Maximum Rate, in which event interest will be calculated on the basis of a year of 365 or 366 days, as the case may be). All interest rate determinations and calculations by Administrative Agent are conclusive and binding absent manifest error. 3.8 MAXIMUM RATE. Regardless of any provision contained in any Loan Document, neither Administrative Agent nor any Lender shall ever be entitled to contract for, charge, take, reserve, receive, or apply, as interest on all or any part of the Obligation, any amount in excess of the Maximum Rate, and, if Lenders ever do so, then such excess shall be deemed a partial prepayment of principal and treated hereunder as such and any remaining excess shall be refunded to Borrower. In determining if the interest paid or payable exceeds the Maximum Rate, Borrower and Lenders shall, to the maximum extent permitted under applicable Law, (a) treat all Borrowings as but a single extension of credit, (b) characterize any non-principal payment as an expense, fee, or premium rather than as interest, (c) exclude voluntary prepayments and the effects thereof, and (d) amortize, prorate, allocate, and spread the total amount of interest throughout the entire contemplated term of the Obligation. However, if the Obligation is paid and performed in full prior to the end of the full contemplated term thereof, and if the interest received for the actual period of existence thereof exceeds the Maximum Amount, Lenders shall refund such excess, and, in such event, Lenders shall not, to the extent permitted by Law, be subject to any penalties provided by any Laws for contracting for, charging, taking, reserving, or receiving interest in excess of the Maximum Amount. If the laws of the state of Texas are applicable for purposes of determining the "Maximum Rate" or the "Maximum Amount," then those terms mean the "weekly ceiling" from time to time in effect under Texas Finance Code Section 303.009, as amended. Borrower agrees that Chapter 346 of the Texas Finance Code, as amended (which regulates certain revolving credit loan accounts and revolving tri-party accounts), does not apply to the Obligation. 3.9 APPLICATION OF PAYMENTS. (a) No Default. If no Event of Default or Potential Default exists, payments and prepayments shall be applied in the order and manner as Borrower may direct. (b) Default. If an Event of Default or Potential Default exists, any payment or prepayment (including proceeds from the exercise of any Rights) shall be applied to the Obligation in the following order: (i) to the ratable payment of all fees, expenses, and indemnities for which Administrative Agent or Lenders have not been paid or reimbursed in accordance with the Loan Documents (as used in this SECTION 3.9(b), a "ratable payment" for any Lender or Administrative Agent shall be, on any date of determination, that proportion which the portion of the total fees, expenses, and indemnities owed to such Lender or Administrative Agent bears to the total aggregate fees and indemnities owed to all Lenders and Administrative Agent on such date of determination); and (ii) to the payment of the remaining Obligation in the order and manner Required Lenders deem appropriate. Subject to the provisions of SECTION 11 and provided that Administrative Agent shall not in any event be bound to inquire into or to determine the validity, scope, or priority of any interest or entitlement of any Lender and may suspend all payments or seek appropriate relief (including, without limitation, instructions from Required Lenders or an action in the nature of interpleader) in the event of any doubt or TERM LOAN AND SECURITY AGREEMENT 19

dispute as to any apportionment or distribution contemplated hereby, Administrative Agent shall promptly distribute such amounts to each Lender in accordance with the Agreement and the related Loan Documents. 3.10 SHARING OF PAYMENTS, ETC. If any Lender shall obtain any payment or prepayment with respect to the Obligation (whether voluntary, involuntary, or otherwise) which is in excess of its share of any such payment in accordance with the relevant Rights of the Lenders under the Loan Documents, then such Lender shall purchase from the other Lenders such participations as shall be necessary to cause such purchasing Lender to share the excess payment with each other Lender in accordance with the relevant Rights under the Loan Documents. If all or any portion of such excess payment is subsequently recovered from such purchasing Lender, then the purchase shall be rescinded and the purchase price restored to the extent of such recovery. Borrower agrees that any Lender purchasing a participation from another Lender pursuant to this SECTION 3.10 may, to the fullest extent permitted by Law, exercise all of its Rights of payment (including the Right of offset) with respect to such participation as fully as if such Lender were the direct creditor of Borrower in the amount of such participation. 3.11 OFFSET. If an Event of Default exists, each Lender shall be entitled to exercise (for the benefit of all Lenders) the Rights of offset and/or banker's Lien against each and every account and other property, or any interest therein, which any Borrower may now or hereafter have with, or which is now or hereafter in the possession of, such Lender to the extent of the full amount of the Obligation. 3.12 COLLECTION OF ACCOUNTS. (a) Borrower (i) shall establish and maintain lock boxes ("LOCKBOXES") at one or more banks set forth on SCHEDULE 2.7, (ii) shall request in writing and otherwise take such reasonable steps to ensure that all Account Debtors forward payment directly to such Lockboxes, (iii) shall and shall cause each of its Subsidiaries to instruct all Account Debtors with respect to the Accounts, General Intangibles, and Negotiable Collateral of such Borrower or such Subsidiary, as the case may be, to remit all Collections in respect thereof to such Lockbox Account, and (iv) shall, and shall cause each of its Subsidiaries to, deposit all other Collections received by Borrower from any source immediately upon receipt in to the Lockboxes. Borrower, each of Borrower's Subsidiaries, Administrative Agent, and the Lockbox Banks shall enter into the Lockbox Agreements, which among other things shall provide for the opening of a Lockbox Account for the deposit of Collections at a Lockbox Bank. Borrower agrees that all Collections and other amounts received by Borrower or any of its Subsidiaries from any Account Debtor or any other source immediately upon receipt shall be deposited into a Lockbox Account. No Lockbox Agreement or arrangement contemplated thereby shall be modified by Borrower or any of its Subsidiaries without the prior written consent of Administrative Agent. Upon the terms and subject to the conditions set forth in the Lockbox Agreements, all amounts received in each Lockbox Account shall be wired each Business Day into the Administrative Agent's Account; provided, however, that Administrative Agent reserves the right, in its sole discretion, to require that any amounts received in a Lockbox Account which may represent amounts attributable to trust funds (i.e., production taxes, severance taxes, or payroll taxes) or amounts attributable to Hydrocarbon Interests of third Persons be segregated by the Lockbox Bank and held in a separate account or otherwise as directed by Administrative Agent. (b) The Lockboxes, Collection Accounts and Designated Account shall be cash collateral accounts, with all cash, checks and similar items of payment in such accounts securing payment of the Obligations and all other Indebtedness, and in which each Loan Party shall have granted a Lien to Administrative Agent hereunder and pursuant to the other Loan Documents. TERM LOAN AND SECURITY AGREEMENT 20

(c) Borrower shall and shall cause its Designated Affiliates, officers, employees, agents, directors or other Persons acting for or in concert with such Borrower (each a "RELATED PERSON") to (i) hold in trust for Administrative Agent all checks, cash and other items of payment received by Borrower or any such Related Person, and (ii) within one (1) Business day after receipt by such Borrower or any Related Person of any checks, cash or other items of payment, deposit the same into a Collection Account of such Borrower. Each Borrower and each Related Person thereof acknowledges and agrees that all cash, checks or items of payment constituting proceeds of Collateral are the property of Administrative Agent for the benefit of Lenders. All proceeds of the sale or other disposition of any Collateral, shall be deposited directly into the applicable Borrower Collection Account. 3.13 CREDITING PAYMENTS; APPLICATION OF COLLECTIONS. The receipt of any Collections by Administrative Agent (whether from transfers to Administrative Agent by the Lockbox Banks pursuant to the Lockbox Agreements or otherwise) immediately shall be applied provisionally to reduce the Obligations outstanding under SECTION 2, but shall not be considered a payment on account unless such Collection item is a wire transfer of immediately available federal funds and is made to the Administrative Agent Account or unless and until such Collection item is honored when presented for payment; provided, however, that Administrative Agent reserves the right, in its sole discretion, to exclude from such provisional reduction and payment the amount of any such Collections that Administrative Agent determines may constitute trust funds (e.g., production taxes, severance taxes, or payroll taxes) or amounts attributable to Hydrocarbon Interests of third Persons. From and after the Closing Date, Administrative Agent shall be entitled to charge Borrower for 1 Business Day of `clearance' or `float' at the rate set forth in SECTION 3.4, on all Collections that are received by the Lockbox Banks or Administrative Agent (regardless of whether forwarded by the Lockbox Banks to Administrative Agent, whether provisionally applied to reduce the Obligations under SECTION 2, or otherwise). This across-the-board 1 Business Day clearance or float charge on all Collections is acknowledged by the parties to constitute an integral aspect of the pricing of the Lender Group's financing of Borrower, and shall apply irrespective of the characterization of whether receipts are owned by Borrower or Administrative Agent, and whether or not there are any outstanding Advances, the effect of such clearance or float charge being the equivalent of charging 1 Business Day of interest on such Collections. Should any Collection item not be honored when presented for payment, then Borrower shall be deemed not to have made such payment, and interest shall be recalculated accordingly. Anything to the contrary contained herein notwithstanding, any Collection item shall be deemed received by Administrative Agent only if it is received into the Administrative Agent Account on a Business Day on or before 2:00 p.m. New York time. If any Collection item is received into the Administrative Agent Account on a non-Business Day or after 2:00 p.m. New York time on a Business Day, it shall be deemed to have been received by Administrative Agent as of the opening of business on the immediately following Business Day. Anything contained herein to the contrary notwithstanding, the economic benefit of the 1 Business Day clearance or float charge provided for in this SECTION 3.13 is not for the ratable benefit of the Lenders, but instead shall be for the sole and separate account of Administrative Agent. SECTION 4. TAXES. 4.1 GENERAL. Any and all payments by Borrower to or for the account of any Lender or Administrative Agent hereunder or under any other Loan Document shall be made free and clear of and without deduction for any and all present or future taxes, excluding, in the case of each Lender and Administrative Agent, taxes imposed on its income and franchise Taxes imposed on it by the jurisdiction under the Laws of which such Lender (or its Applicable Lending Office) or Administrative Agent (as the case may be) is organized or the jurisdiction in which the principal office or the Applicable Lending TERM LOAN AND SECURITY AGREEMENT 21

Office of such Lender or Administrative Agent is located, or any political subdivision thereof (all such non-excluded taxes, referred to herein as "TAXES"). If Borrower shall be required by Law to deduct any Taxes from or in respect of any sum payable under any Loan Document to any Lender or Administrative Agent, (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this SECTION 4.1) such Lender or Administrative Agent receives an amount equal to the sum it would have received had no such deductions been made, (ii) Borrower shall make such deductions, (iii) Borrower shall pay the full amount deducted to the relevant taxation authority or other authority in accordance with applicable Law, and (iv) Borrower shall furnish to Administrative Agent, the original or a certified copy of a receipt evidencing payment thereof. 4.2 STAMP AND DOCUMENTARY TAXES. In addition, Borrower agrees to pay any and all present or future stamp or documentary taxes and any other excise or property taxes or charges or similar levies which arise from any payment made under any Loan Document or from the execution or delivery of, or otherwise with respect to, any Loan Document (hereinafter referred to as "OTHER TAXES"). 4.3 INDEMNIFICATION FOR TAXES. Borrower agrees to indemnify each Lender and Administrative Agent for the full amount of Taxes and Other Taxes (including, without limitation, any Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable under this SECTION 4) paid by such Lender or Administrative Agent (as the case may be) and any liability (including penalties, interest, and expenses) arising therefrom or with respect thereto. 4.4 CHANGES IN APPLICABLE LENDING OFFICE. If Borrower is required to pay or will be required to pay additional amounts to or for the account of any Lender pursuant to this SECTION 4.4, then such Lender will agree to use reasonable efforts to change the jurisdiction of its Applicable Lending Office so as to eliminate or reduce any such additional payment which may thereafter accrue if such change, in the judgment of such Lender, is not otherwise disadvantageous to such Lender. 4.5 SURVIVAL. Without prejudice to the survival of any other agreement of Borrower hereunder, the agreements and obligations of Borrower contained in this SECTION 4 shall survive the payment in full of the Obligation. SECTION 5. SECURITY. 5.1 COLLATERAL. To secure the full and complete payment and performance of the Obligation, Borrower shall enter into Collateral Documents (in form and substance acceptable to Administrative Agent) pursuant to which, among other things, Borrower shall grant, pledge, assign, and create first priority Liens in favor of Administrative Agent (for the ratable benefit of Lenders) in and to all of the Borrower's assets including (but not limited to): (i) the Oil and Gas Properties and (ii) the Personal Property Collateral. 5.2 GRANT OF SECURITY INTEREST IN PERSONAL PROPERTY COLLATERAL. Borrower hereby grants to Administrative Agent, for the benefit of the Lenders, a continuing security interest in all of its right, title, and interest in all currently existing and hereafter acquired or arising Personal Property Collateral in order to secure prompt repayment of any and all of the Obligations in accordance with the terms and conditions of the Loan Documents and in order to secure prompt performance by Borrower of each of its covenants and duties under the Loan Documents. Administrative Agent's Liens in and to the Personal Property Collateral shall attach to all Personal Property Collateral without further act on the part of Administrative Agent or Borrower. Anything contained in this Agreement or any other Loan Document TERM LOAN AND SECURITY AGREEMENT 22

to the contrary notwithstanding, except for dispositions permitted by SECTION 9.5, Borrower has no authority, express or implied, to dispose of any item or portion of the Collateral. 5.3 NEGOTIABLE COLLATERAL AND CHATTEL PAPER. Borrower covenants and agrees with Lenders that from and after the Closing Date and until the date of termination of this Agreement: (a) In the event that any Collateral, including proceeds, is evidenced by or consists of Negotiable Collateral, and if and to the extent that perfection or priority of Administrative Agent's security interest with respect to such Collateral is dependent on or enhanced by possession, Borrower, immediately upon the request of Administrative Agent, shall endorse and deliver physical possession of such Negotiable Collateral to Administrative Agent; (b) Borrower shall take all steps reasonably necessary to grant Administrative Agent control of all electronic Chattel Paper in accordance with the Code and all "transferable records" as defined in each of the Uniform Electronic Transactions Act and the Electronic Signatures in Global and National Commerce Act; and (c) In the event Borrower, with Administrative Agent's consent, retains possession of any Chattel Paper or instruments otherwise required to be endorsed and delivered to Administrative Agent pursuant to SECTION 5.3(a), all of such Chattel Paper and instruments shall be marked with the following legend: "This writing and the obligations evidenced or secured thereby are subject to the security interest of Mid River LLC, as Administrative Agent." 5.4 DELIVERY OF ADDITIONAL DOCUMENTATION REQUIRED. Borrower authorizes Administrative Agent to file, transmit, or communicate, as applicable, UCC financing statements, in-lieu financing statements and amendments describing the Personal Property Collateral as "all personal property of debtor" or "all assets of debtor" or words of similar effect, in order to perfect Administrative Agent's Liens on the Personal Property Collateral without Borrower's signature. Notwithstanding the foregoing, at any time upon the request of Administrative Agent, Borrower shall execute (or cause to be executed) and deliver to Administrative Agent, any and all financing statements, original financing statements in lieu of continuation statements, fixture filings, security agreements, pledges, assignments, endorsements of certificates of title, and all other documents (the "ADDITIONAL DOCUMENTS") upon which Borrower's signature may be required that Administrative Agent may request, in form and substance satisfactory to Administrative Agent, to perfect and continue perfected or better perfect Administrative Agent's Liens in the Collateral (whether now owned or hereafter arising or acquired), to create and perfect Liens in favor of Administrative Agent in any Collateral (including, but not limited to, Oil and Gas Property) acquired after the Closing Date, and in order to fully consummate all of the transactions contemplated hereby and under the other Loan Documents. To the maximum extent permitted by applicable law, Borrower authorizes Administrative Agent to execute any such Additional Documents in Borrower's name and authorizes Administrative Agent to file such executed Additional Documents in any appropriate filing office. Borrower also hereby ratifies its authorization for Administrative Agent to have filed in any jurisdiction any financing statements or amendments thereto if filed prior to the date hereof. Borrower shall not terminate, amend or file a correction statement with respect to any Code financing statement filed pursuant to this SECTION 5.4 without Administrative Agent's prior written consent. In addition, on such periodic basis as Administrative Agent shall require, Borrower shall (a) provide Administrative Agent with a report of all new patentable, copyrightable, or trademarkable materials acquired or generated by Borrower during the prior period, (b) cause all patents, copyrights, and trademarks acquired or generated by Borrower that are not already the subject of a registration with the appropriate filing office (or an application therefor diligently prosecuted) to be registered with such appropriate filing office in a manner sufficient to impart constructive notice of Borrower's ownership thereof, and (c) cause to be prepared, executed, and delivered to Administrative Agent supplemental schedules to the applicable Loan TERM LOAN AND SECURITY AGREEMENT 23

Documents to identify such patents, copyrights, and trademarks as being subject to the security interests created thereunder. Borrower grants Administrative Agent a power-of-attorney, irrevocable so long as this Agreement is in existence, to amend SCHEDULE P to include any Proprietary Rights including (but not limited to) future Trademarks. 5.5 POWER OF ATTORNEY. Borrower hereby irrevocably makes, constitutes, and appoints Administrative Agent (and any of Administrative Agent's officers, employees, or agents designated by Administrative Agent) as Borrower's true and lawful attorney, with power to (a) if Borrower refuses to, or fails timely to execute and deliver any of the documents described in SECTION 5.4, sign the name of Borrower on any of the documents described in SECTION 5.4, (b) sign Borrower's name on any invoice or bill of lading relating to the Collateral, drafts against Account Debtors, or notices to Account Debtors, (c) send requests for verification of Accounts, (d) endorse Borrower's name on any Collection item that may come into the Lender Group's possession, (e) make, settle, and adjust all claims under Borrower's policies of insurance and make all determinations and decisions with respect to such policies of insurance, and (f) settle and adjust disputes and claims respecting the Accounts, Chattel Paper, or General Intangibles directly with Account Debtors, for amounts and upon terms that Administrative Agent determines to be reasonable, and Administrative Agent may cause to be executed and delivered any documents and releases that Administrative Agent determines to be necessary.

SECTION 11. RIGHTS AND REMEDIES. TERM LOAN AND SECURITY AGREEMENT 51

11.1 REMEDIES UPON EVENT OF DEFAULT. (a) Debtor Relief. If an Event of Default exists under SECTION 10.6 or 10.7, the commitment to extend credit hereunder shall automatically terminate and the entire unpaid balance of the Obligation shall automatically become due and payable without any action or notice of any kind whatsoever. (b) Other Event of Defaults. If any Event of Default exists, Administrative Agent may (and, subject to the terms of SECTION 12, shall upon the request of Required Lenders) or Required Lenders may, do any one or more of the following: (i) if the maturity of the Obligation has not already been accelerated under SECTION 11.1(a), declare the entire unpaid balance of the Obligation, or any part thereof, immediately due and payable, whereupon it shall be due and payable; (ii) terminate the commitments of Lenders to extend credit hereunder; (iii) reduce any claim to judgment; (iv) to the extent permitted by Law, exercise (or request each Lender to, and each Lender shall be entitled to, exercise) the Rights of offset or banker's Lien against the interest of each Borrower in and to every account and other property of any Borrower which are in the possession of Administrative Agent or any Lender to the extent of the full amount of the Obligation (to the extent permitted by Law, each Loan Party being deemed directly obligated to each Lender in the full amount of the Obligation for such purposes); and (v) exercise any and all other legal or equitable Rights afforded by the Loan Documents, the Laws of the State of New York, or any other applicable jurisdiction as Administrative Agent or Required Lenders (as the case may be) shall deem appropriate, or otherwise, including, but not limited to, the Right to bring suit or other proceedings before any Governmental Authority either for specific performance of any covenant or condition contained in any of the Loan Documents or in aid of the exercise of any Right granted to Administrative Agent or any Lender in any of the Loan Documents. (c) Settle or adjust disputes and claims directly with Account Debtors for amounts and upon terms which Administrative Agent considers advisable, and in such cases, Administrative Agent will credit the Loan Account with only the net amounts received by Administrative Agent in payment of such disputed Accounts after deducting all Lender Group Expenses incurred or expended in connection therewith; (d) Cause Borrower to hold all returned Inventory in trust for the Lenders, segregate all returned Inventory from all other assets of Borrower or in Borrower's possession and conspicuously label said returned Inventory as the property of the Lender Group; (e) Without notice to or demand upon Borrower, make such payments and do such acts as Administrative Agent considers necessary or reasonable to protect its security interests in the Collateral. Borrower agrees to assemble the Personal Property Collateral if Administrative Agent so requires, and to make the Personal Property Collateral available to Administrative Agent at a place that Administrative Agent may designate which is reasonably convenient to both parties. Borrower authorizes Administrative Agent to enter the premises where the Personal Property Collateral is located, to take and maintain possession of the Personal Property Collateral, or any part of it, and to pay, purchase, contest, or compromise any Lien that in Administrative Agent's determination appears to conflict with Administrative Agent's Liens and to pay all expenses incurred in connection therewith and to charge Borrower's Loan Account therefor. With respect to any of Borrower's owned or leased premises, Borrower hereby grants Administrative Agent a license to enter into possession of such premises and to occupy the same, without charge, in order to exercise any of the Lender Group's rights or remedies provided herein, at law, in equity, or otherwise; TERM LOAN AND SECURITY AGREEMENT 52

(f) Without notice to Borrower (such notice being expressly waived), and without constituting a retention of any collateral in satisfaction of an obligation (within the meaning of the UCC), set off and apply to the Obligations any and all (i) balances and deposits of Borrower held by the Lenders, or (ii) Debt at any time owing to or for the credit or the account of Borrower held by the Lenders; (g) Hold, as cash collateral, any and all balances and deposits of Borrower held by the Lender Group, to secure the full and final repayment of all of the Obligations; (h) Ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell (in the manner provided for herein) the Personal Property Collateral.

It is not necessary that the Personal Property Collateral be present at any such sale; (j) Administrative Agent shall give notice of the disposition of the Personal Property Collateral as follows: (i) Administrative Agent shall give Borrower a notice in writing of the time and place of public sale, or, if the sale is a private sale or some other disposition other than a public sale is to be made of the Personal Property Collateral, the time on or after which the private sale or other disposition is to be made; and (ii) The notice shall be personally delivered or mailed, postage prepaid, to Borrower as provided in SECTION 13, at least five (5) days before the earliest time of disposition set forth in the notice; no notice needs to be given prior to the disposition of any portion of the Personal Property Collateral that is perishable or threatens to decline speedily in value or that is of a type customarily sold on a recognized market; (iii) Administrative Agent, on behalf of the Lender Group may credit bid and purchase at any public sale; 11.2 WAIVERS. To the extent permitted by Law, the Loan Parties hereby waive presentment and demand for payment, protest, notice of intention to accelerate, notice of acceleration, and notice of protest and nonpayment, and agree that their respective liability with respect to the Obligation (or any part thereof) shall not be affected by any renewal or extension in the time of payment of the Obligation (or any part thereof), by any indulgence, or by any release or change in any security for the payment of the Obligation (or any part thereof). 11.3 PERFORMANCE BY ADMINISTRATIVE AGENT. If any covenant, duty, or agreement of any Loan Party is not performed in accordance with the terms of the Loan Documents, after the occurrence and during the continuance of an Event of Default, Administrative Agent may, at its option (but subject to the approval of Required Lenders), perform or attempt to perform such covenant, duty, or agreement on TERM LOAN AND SECURITY AGREEMENT 53

behalf of such Loan Party. In such event, any amount expended by Administrative Agent in such performance or attempted performance shall be payable by the Loan Parties, jointly and severally, to Administrative Agent on demand, shall become part of the Obligation, and shall bear interest at the Post-Default Rate from the date of such expenditure by Administrative Agent until paid. Notwithstanding the foregoing, it is expressly understood that Administrative Agent does not assume, and shall never have, except by its express written consent, any liability or responsibility for the performance of any covenant, duty, or agreement of any Borrower. 11.4 DELEGATION OF DUTIES; RELIANCE. Administrative Agent may perform any of its duties or exercise any of its Rights under the Loan Documents by or through its Representatives. Administrative Agent and its Representatives shall (a) be entitled to rely upon (and shall be protected in relying upon) any writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telecopy, telegram, telex or teletype message, statement, order, or other documents or conversation believed by it or them to be genuine and correct and to have been signed or made by the proper Person and, with respect to legal matters, upon opinion of counsel selected by Administrative Agent, (b) be entitled to deem and treat each Lender as the owner and Lender of the Obligation owed to such Lender for all purposes until, subject to SECTION 13.12, written notice of the assignment or transfer thereof shall have been given to and received by Administrative Agent (and any request, authorization, consent, or approval of any Lender shall be conclusive and binding on each subsequent Lender, assignee, or transferee of the Obligation owed to such Lender or portion thereof until such notice is given and received), (c) not be deemed to have notice of the occurrence of an Event of Default unless a responsible officer of Administrative Agent, who handles matters associated with the Loan Documents and transactions thereunder, has received written notice from a Lender or Borrower and stating that such notice is a "Notice of Default," and (d) be entitled to consult with legal counsel (including counsel for Borrower), independent accountants, and other experts selected by Administrative Agent and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants, or experts. 11.5 NOT IN CONTROL. Nothing in any Loan Document shall, or shall be deemed to (a) give Administrative Agent or any Lender the Right to exercise control over the assets (including real property), affairs, or management of any Loan Party, (b) preclude or interfere with compliance by any Loan Party thereof with any Law, or (c) require any act or omission by any Loan Party thereof that may be harmful to Persons or property. Any "Material Adverse Effect" or other materiality qualifier in any representation, warranty, covenant, or other provision of any Loan Document is included for credit documentation purposes only and shall not, and shall not be deemed to, mean that Administrative Agent or any Lender acquiesces in any non-compliance by any Loan Party with any Law or document, or that Administrative Agent or any Lender does not expect the Loan Parties to promptly, diligently, and continuously carry out all appropriate removal, remediation, and termination activities required or appropriate in accordance with all Environmental Laws. The Administrative Agent and the Lenders have no fiduciary relationship with or fiduciary duty to any Loan Party arising out of or in connection with the Loan Documents, and the relationship between the Administrative Agent and the Lenders, on the one hand, and Loan Parties, on the other hand, in connection with the Loan Documents is solely that of debtor and creditor. The power of the Administrative Agent and Lenders under the Loan Documents is limited to the Rights provided in the Loan Documents, which Rights exist solely to assure payment and performance of the Obligation and may be exercised in a manner calculated by the Administrative Agent and Lenders in their respective good faith business judgment. 11.6 COURSE OF DEALING. The acceptance by Administrative Agent or Lenders at any time and from time to time of partial payment on the Obligation shall not be deemed to be a waiver of any Event of Default then existing. No waiver by Administrative Agent, Required Lenders, or Lenders of any Event of Default shall be deemed to be a waiver of any other then-existing or subsequent Event of Default. No delay or omission by Administrative Agent, Required Lenders, or Lenders in exercising any Right under TERM LOAN AND SECURITY AGREEMENT 54

the Loan Documents shall impair such Right or be construed as a waiver thereof or any acquiescence therein, nor shall any single or partial exercise of any such Right preclude other or further exercise thereof, or the exercise of any other Right under the Loan Documents or otherwise. 11.7 CUMULATIVE RIGHTS. All Rights available to Administrative Agent and Lenders under the Loan Documents are cumulative of and in addition to all other Rights granted to Administrative Agent and Lenders at law or in equity, whether or not the Obligation is due and payable and whether or not Administrative Agent or Lenders have instituted any suit for collection, foreclosure, or other action in connection with the Loan Documents. 11.8 APPLICATION OF PROCEEDS. Any and all proceeds ever received by Administrative Agent or Lenders from the exercise of any Rights pertaining to the Obligation shall be applied to the Obligation in the order and manner set forth in SECTION 3.9. 11.9 CERTAIN PROCEEDINGS. Each Loan Party will promptly execute and deliver, or cause the execution and delivery of, all applications, certificates, instruments, registration statements, and all other documents and papers Administrative Agent or Lenders may reasonably request in connection with the obtaining of any consent, approval, registration, qualification, permit, license, or Authorization of any Governmental Authority or other Person necessary or appropriate for the effective exercise of any Rights under the Loan Documents. Because the Loan Parties agree that Administrative Agent's and Lenders' remedies at Law for failure of the Loan Parties to comply with the provisions of this Section would be inadequate and that such failure would not be adequately compensable in damages, the Loan Parties agree that the covenants of this Section may be specifically enforced. 11.10 EXPENDITURES BY LENDERS. Borrower shall promptly pay within fifteen (15) Business Days after request therefor (a) all reasonable costs, fees, and expenses paid or incurred by Administrative Agent, incident to any Loan Document (including, but not limited to, the reasonable fees and expenses of counsel to Administrative Agent in connection with the negotiation, preparation, delivery, execution, coordination, and administration of the Loan Documents and any related amendment, waiver, or consent) and (b) all reasonable costs and expenses of Lenders and Administrative Agent incurred by Administrative Agent or any Lender in connection with the enforcement of the obligations of any Borrower arising under the Loan Documents (including, without limitation, costs and expenses incurred in connection with any workout or bankruptcy) or the exercise of any Rights arising under the Loan Documents (including, but not limited to, reasonable attorneys' fees including allocated cost of internal counsel, court costs, and other costs of collection), all of which shall be a part of the Obligation and shall bear interest at the Post-Default Rate from the date due until the date repaid. 11.11 INDEMNIFICATION. Borrower agrees, to indemnify and hold harmless Administrative Agent, and each Lender, and each of their respective affiliates and their respective officers, directors, employees, agents, attorneys, and advisors (each, an "Indemnified Party") from and against any and all claims, damages, losses, liabilities (including, without limitation, any Environmental Liabilities), costs, and expenses (including, without limitation, reasonable attorneys' fees) that may be incurred by or asserted or awarded against any Indemnified Party, in each case arising out of or in connection with or by reason of (including, without limitation, in connection with any investigation, litigation, or proceeding or preparation of defense in connection therewith) the Loan Documents, any of the transactions contemplated herein or the actual or proposed use of the proceeds of the Borrowings (including any of the foregoing arising from the negligence of the Indemnified Party), except to the extent such claim, damage, loss, liability, cost, or expense is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from such Indemnified Party's gross negligence or willful misconduct. In the case of an investigation, litigation, or other proceeding to which the indemnity in this SECTION 11.11 TERM LOAN AND SECURITY AGREEMENT 55

applies, such indemnity shall be effective whether or not such investigation, litigation, or proceeding is brought by Borrower, any other Loan Party, their directors, shareholders, or creditors or an Indemnified Party or any other Person or any Indemnified Party is otherwise a party thereto and whether or not the transactions contemplated hereby are consummated. Borrower agrees not to assert any claim against any indemnified party on any theory of liability, for special, indirect, consequential, or punitive damages arising out of or otherwise relating to the Loan Documents, any of the transactions contemplated herein or the actual or proposed use of the proceeds of the Borrowings. Without prejudice to the survival of any other agreement of the Loan Parties hereunder, the agreements and obligations of the Loan Parties contained in this SECTION 11.11 shall survive the payment in full of the Borrowings and all other amounts payable under the Loan Documents. SECTION 12. AGREEMENT AMONG LENDERS. 12.1 ADMINISTRATIVE AGENT. (a) Appointment of Administrative Agent. Each Lender hereby appoints Mid River LLC (and Mid River LLC hereby accepts such appointment) as its nominee and agent, in its name and on its behalf: (i) to act as nominee for and on behalf of such Lender in and under all Loan Documents; (ii) to arrange the means whereby the funds of Lenders are to be made available to Borrower under the Loan Documents; (iii) to take such action as may be requested by any Lender under the Loan Documents (when such Lender is entitled to make such request under the Loan Documents and after such requesting Lender has obtained the concurrence of such other Lenders as may be required under the Loan Documents); (iv) to receive all documents and items to be furnished to Lenders under the Loan Documents; (v) to timely distribute, and Administrative Agent agrees to so distribute, to each Lender all material information, requests, documents, and items received from Borrower under the Loan Documents; (vi) to promptly distribute to each Lender its ratable part of each payment or prepayment (whether voluntary, as proceeds of Collateral upon or after foreclosure, as proceeds of insurance thereon, or otherwise) in accordance with the terms of the Loan Documents; and (vii) to deliver to the appropriate Persons requests, demands, approvals, and consents received from Lenders; provided, however, Administrative Agent shall not be required to take any action which exposes Administrative Agent to personal liability or which is contrary to the Loan Documents or applicable Law. (b) Resignation or Removal of Administrative Agent. Successor Administrative Agent. Administrative Agent may resign at any time with or without cause as Administrative Agent under the Loan Documents by giving written notice thereof to Lenders and may be removed as Administrative Agent under the Loan Documents at any time with cause by Required Lenders. Should the initial or any successor Administrative Agent ever cease to be a party hereto or should the initial or any successor Administrative Agent ever resign or be removed as Administrative Agent, then Required Lenders shall elect the successor Administrative Agent from among the Lenders (other than the resigning Administrative Agent). If no successor Administrative Agent shall have been so appointed by Required Lenders, within 30 days after the retiring Administrative Agent's giving of notice of resignation or Required Lenders' removal of the retiring Administrative Agent, then the retiring Administrative Agent may, on behalf of Lenders, appoint a successor Administrative Agent. Upon the acceptance of any appointment as Administrative Agent under the Loan Documents by a successor Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the Rights of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations of Administrative Agent under the Loan Documents, and each Lender shall execute such documents as any Lender may reasonably request to reflect such change in and under the Loan Documents. After any retiring Administrative Agent's resignation TERM LOAN AND SECURITY AGREEMENT 56

or removal as Administrative Agent under the Loan Documents, the provisions of this SECTION 12 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Administrative Agent under the Loan Documents. (c) Administrative Agent as a Lender. Non-Fiduciary. Administrative Agent, in its capacity as a Lender, shall have the same Rights under the Loan Documents as any other Lender and may exercise the same as though it were not acting as Administrative Agent; the term "Lender" shall, unless the context otherwise indicates, include Administrative Agent; and any resignation, or removal of Administrative Agent hereunder shall not impair or otherwise affect any Rights which it has or may have in its capacity as an individual Lender. Each Lender and Borrower agree that Administrative Agent is not a fiduciary for Lenders or for Borrower but simply is acting in the capacity described herein to alleviate administrative burdens for both Borrower and Lenders, that Administrative Agent has no duties or responsibilities to Lenders or Borrower except those expressly set forth herein, and that Administrative Agent in its capacity as a Lender has all Rights of any other Lender. (d) Other Activities of Administrative Agent. Administrative Agent and its Affiliates may now or hereafter be engaged in one or more loan, letter of credit, leasing, or other financing transactions with Borrower, act as trustee or depositary for Borrower, or otherwise be engaged in other transactions with Borrower (collectively, the "OTHER ACTIVITIES") not the subject of the Loan Documents. Without limiting the Rights of Lenders specifically set forth in the Loan Documents, Administrative Agent and its Affiliates shall not be responsible to account to Lenders for such other activities, and no Lender shall have any interest in any other activities, any present or future guaranties by or for the account of Borrower which are not contemplated or included in the Loan Documents, any present or future offset exercised by Administrative Agent and its Affiliates in respect of such other activities, any present or future property taken as security for any such other activities, or any property now or hereafter in the possession or control of Administrative Agent or its Affiliates which may be or become security for the obligations of Borrower arising under the Loan Documents by reason of the general description of indebtedness secured or of property contained in any other agreements, documents, or instruments related to any such other activities; provided that, if any payments in respect of such guaranties or such property or the proceeds thereof shall be applied to reduction of the Obligation, then each Lender shall be entitled to share in such application ratably. 12.2 EXPENSES. Upon demand by Administrative Agent, each Lender shall pay its ratable portion (determined as of the date reimbursement is sought hereunder) of any reasonable expenses (including, without limitation, court costs, reasonable attorneys' fees, and other costs of collection) incurred by Administrative Agent in connection with any of the Loan Documents if and to the extent such Administrative Agent does not receive reimbursement therefor from other sources within 60 days after incurred; provided that, each Lender shall be entitled to receive its ratable portion of any reimbursement for such expenses, or part thereof, which Administrative Agent subsequently receives from such other sources. 12.3 PROPORTIONATE ABSORPTION OF LOSSES. Except as otherwise provided in the Loan Documents, nothing in the Loan Documents shall be deemed to give any Lender any advantage over any other Lender insofar as the Obligation is concerned, or to relieve any Lender from absorbing its ratable portion of any losses sustained with respect to the Obligation (except to the extent such losses result from unilateral actions or inactions of any Lender that are not made in accordance with the terms and provisions of the Loan Documents). TERM LOAN AND SECURITY AGREEMENT 57

12.4 DELEGATION OF DUTIES; RELIANCE. Administrative Agent may perform any of its duties or exercise any of its Rights under the Loan Documents by or through its Representatives. Administrative Agent and its Representatives shall (a) be entitled to rely upon (and shall be protected in relying upon) any writing, resolution, notice, consent, certificate, affidavit, letter, cablegram, telecopy, telegram, telex or teletype message, statement, order, or other documents or conversation believed by it or them to be genuine and correct and to have been signed or made by the proper Person and, with respect to legal matters, upon opinion of counsel selected by Administrative Agent, (b) be entitled to deem and treat each Lender as the owner and Lender of the Obligation owed to such Lender for all purposes until, subject to SECTION 13.12, written notice of the assignment or transfer thereof shall have been given to and received by Administrative Agent (and any request, authorization, consent, or approval of any Lender shall be conclusive and binding on each subsequent Lender, assignee, or transferee of the Obligation owed to such Lender or portion thereof until such notice is given and received), (c) not be deemed to have notice of the occurrence of an Event of Default or Potential Default unless a responsible officer of Administrative Agent, who handles matters associated with the Loan Documents and transactions thereunder, has received written notice from a Lender or Borrower and stating that such notice is a "Notice of Default," and (d) be entitled to consult with legal counsel (including counsel for Borrower), independent accountants, and other experts selected by Administrative Agent and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts. 12.5 LIMITATION OF LIABILITY. (a) General. Neither Administrative Agent nor any of its Representatives shall be liable for any action taken or omitted to be taken by it or them under the Loan Documents in good faith and reasonably believed by it or them to be within the discretion or power conferred upon it or them by the Loan Documents or be responsible for the consequences of any error of judgment, except for fraud, gross negligence, or willful misconduct; and neither Administrative Agent nor any of its Representatives has a fiduciary relationship with any Lender by virtue of the Loan Documents (provided that, nothing herein shall negate the obligation of Administrative Agent to account for funds received by it for the account of any Lender). (b) Non-Discretionary Actions, Indemnification. Unless indemnified to its satisfaction against loss, cost, liability, and expense, Administrative Agent shall not be compelled to do any act under the Loan Documents or to take any action toward the execution or enforcement of the powers thereby created or to prosecute or defend any suit in respect of the Loan Documents. If Administrative Agent requests instructions from Lenders or Required Lenders, as the case may be, with respect to any act or action (including, but not limited to, any failure to act) in connection with any Loan Document, Administrative Agent shall be entitled (but shall not be required) to refrain (without incurring any liability to any Person by so refraining) from such act or action unless and until it has received such instructions. Except where action of Required Lenders or all Lenders is required in the Loan Documents, Administrative Agent may act hereunder in its own discretion without requesting instructions. In no event, however, shall Administrative Agent or any of its Representatives be required to take any action which it or they determine could incur for it or them criminal or onerous civil liability. Without limiting the generality of the foregoing, no Lender shall have any right of action against Administrative Agent as a result of Administrative Agent's acting or refraining from acting hereunder in accordance with the instructions of Required Lenders (or all Lenders if required in the Loan Documents). (c) Independent Credit Decision. Administrative Agent shall not be responsible in any manner to any Lender or any Participant for, and each Lender represents and warrants that it has not relied upon Administrative Agent in respect of, (i) the creditworthiness of any Borrower TERM LOAN AND SECURITY AGREEMENT 58

and the risks involved to such Lender, (ii) the effectiveness, enforceability, genuineness, validity, or the due execution of any Loan Document, (iii) any representation, warranty, document, certificate, report, or statement made therein or furnished thereunder or in connection therewith, (iv) the existence, priority, or perfection of any Lien hereafter granted or purported to be granted under any Loan Document, or (v) observation of or compliance with any of the terms, covenants, or conditions of any Loan Document on the part of any Borrower. Each Lender agrees to indemnify Administrative Agent and its Representatives and hold them harmless from and against (but limited to such Lender's Pro Rata Part of) any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, reasonable expenses, and reasonable disbursements of any kind or nature whatsoever which may be imposed on, asserted against, or incurred by them in any way relating to or arising out of the Loan Documents or any action taken or omitted by them under the Loan Documents (INCLUDING ANY OF THE FOREGOING ARISING FROM THE NEGLIGENCE OF ADMINISTRATIVE AGENT OR ITS REPRESENTATIVES), to the extent Administrative Agent and its Representatives are not reimbursed for such amounts by any Borrower (provided that, Administrative Agent and its Representatives shall not have the Right to be indemnified hereunder for its or their own fraud, gross negligence, or willful misconduct). 12.6 EVENT OF DEFAULT; COLLATERAL. (a) Upon the occurrence and continuance of an Event of Default, Lenders agree to promptly confer in order that Required Lenders or Lenders, as the case may be, may agree upon a course of action for the enforcement of the Rights of Lenders; and Administrative Agent shall be entitled to refrain from taking any action (without incurring any liability to any Person for so refraining) unless and until Administrative Agent shall have received instructions from Required Lenders. All Rights of action under the Loan Documents and all Rights to the Collateral, if any, hereunder may be enforced by Administrative Agent and any suit or proceeding instituted by Administrative Agent in furtherance of such enforcement shall be brought in its name as Administrative Agent without the necessity of joining as plaintiffs or defendants any Lender, and the recovery of any judgment shall be for the benefit of Lenders subject to the expenses of Administrative Agent. In actions with respect to any property of the Loan Parties, Administrative Agent is acting for the ratable benefit of each Lender. Any and all agreements to subordinate (whether made heretofore or hereafter) other indebtedness or obligations of the Loan Parties to the Obligation shall be construed as being for the ratable benefit of each Lender. (b) Each Lender authorizes and directs Administrative Agent to enter into the Collateral Documents for the benefit of the Lenders. Except to the extent unanimity or a supermajority is required hereunder, each Lender agrees that any action taken by the Required Lenders in accordance with the provisions of the Loan Documents, and the exercise by the Required Lenders of the powers set forth herein or therein, together with such other powers as are reasonably incidental thereto, shall be authorized and binding upon all of the Lenders. (c) Administrative Agent is hereby authorized on behalf of all of the Lenders, without the necessity of any notice to or further consent from any Lender, from time to time to take any action with respect to any Collateral or Collateral Documents which may be necessary to perfect and maintain perfected the Liens upon the Collateral granted pursuant to the Collateral Documents. (d) Administrative Agent shall have no obligation whatsoever to any Lender or to any other Person to assure that the Collateral exists or is owned by any Borrower or is cared for, protected, or insured or has been encumbered or that the Liens granted to Administrative Agent herein or pursuant hereto have been properly or sufficiently or lawfully created, perfected, TERM LOAN AND SECURITY AGREEMENT 59

protected, or enforced, or are entitled to any particular priority, or to exercise at all or in any particular manner or under any duty of care, disclosure, or fidelity, or to continue exercising, any of the Rights granted or available to Administrative Agent in this SECTION 12.6 or in any of the Collateral Documents; it being understood and agreed that in respect of the Collateral, or any act, omission, or event related thereto, Administrative Agent may act in any manner it may deem appropriate, in its sole discretion, given Administrative Agent's own interest in the Collateral as one of the Lenders and that Administrative Agent shall have no duty or liability whatsoever to any Lender, other than to act without gross negligence or willful misconduct. (e) Lenders hereby irrevocably authorize Administrative Agent, at its option and in its discretion, to release any Lien granted to or held by Administrative Agent upon any Collateral: (i) upon payment and satisfaction of the Obligation; (ii) constituting property in which no Borrower or Parent owned an interest at the time the Lien was granted or at any time thereafter; (iii) upon the sale, transfer, or disposition of Collateral which is expressly permitted pursuant to the Loan Documents; or (iv) if approved, authorized, or ratified in writing by all necessary Lenders. Upon request by Administrative Agent at any time, Lenders will confirm in writing Administrative Agent's authority to release particular types or items of Collateral pursuant to this SECTION 12.6. (f) In furtherance of the authorizations set forth in this SECTION 12.6, each Lender hereby irrevocably appoints Administrative Agent its attorney-in-fact, with full power of substitution, for and on behalf of and in the name of each such Lender, (i) to enter into Collateral Documents (including, without limitation, any appointments of substitute trustees under any Collateral Document), (ii) to take action with respect to the Collateral and Collateral Documents to perfect, maintain, and preserve Lender's Liens, and (iii) to execute instruments of release or to take other action necessary to release Liens upon any Collateral to the extent authorized in PARAGRAPH (e) hereof. This power of attorney shall be liberally, not restrictively, construed so as to give the greatest latitude to Administrative Agent's power, as attorney, relative to the Collateral matters described in this SECTION 12.6. The powers and authorities herein conferred on Administrative Agent may be exercised by Administrative Agent through any Person who, at the time of the execution of a particular instrument, is an officer of Administrative Agent. The power of attorney conferred by this SECTION 12.6(f) is granted for valuable consideration and is coupled with an interest and is irrevocable so long as the Obligation, or any part thereof, shall remain unpaid or Lenders are obligated to make any Borrowings under the Loan Documents. 12.7 LIMITATION OF LIABILITY. To the extent permitted by Law, (a) Administrative Agent (acting in its agent capacity) shall not incur any liability to any other Lender or Participant except for acts or omissions resulting from its own fraud, gross negligence or willful misconduct, and (b) neither Administrative Agent nor any Lender or Participant shall incur any liability to any other Person for any act or omission of any other Lender or Participant. 12.8 RELATIONSHIP OF LENDERS. Nothing herein shall be construed as creating a partnership or joint venture among Administrative Agent and Lenders. 12.9 BENEFITS OF AGREEMENT. None of the provisions of this SECTION 12 shall inure to the benefit of any Borrower or any other Person other than Lenders; consequently, no Borrower or any other Person shall be entitled to rely upon, or to raise as a defense, in any manner whatsoever, the failure of Administrative Agent or any Lender to comply with such provisions. TERM LOAN AND SECURITY AGREEMENT 60

12.10 OBLIGATIONS SEVERAL. The obligations of Lenders hereunder are several, and each Lender hereunder shall not be responsible for the obligations of the other Lenders hereunder, nor will the failure of one Lender to perform any of its obligations hereunder relieve the other Lenders from the performance of their respective obligations hereunder. SECTION 13. MISCELLANEOUS. 13.1 HEADINGS. The headings, captions, and arrangements used in any of the Loan Documents are, unless specified otherwise, for convenience only and shall not be deemed to limit, amplify, or modify the terms of the Loan Documents, nor affect the meaning thereof. 13.2 NONBUSINESS DAYS. In any case where any payment or action is due under any Loan Document on a day which is not a Business Day, such payment or action may be delayed until the next-succeeding Business Day, but interest and fees shall continue to accrue in respect of any payment to which it is applicable until such payment is in fact made. 13.3 COMMUNICATIONS. Unless otherwise specifically provided herein or any other Loan Document, all notices shall be in writing addressed to the respective party as set forth below and may be personally served, faxed, telecopied, or sent by overnight courier service or United States mail and shall be deemed to have been given: (a) if delivered in person, when delivered; (b) if delivered by fax or telecopy, on the date of transmission if transmitted on a Business Day before 4:00 p.m. New York time or, if not, on the next succeeding Business Day; (c) if delivered by overnight courier, the next succeeding Business Day after delivery to such courier properly addressed; or (d) if by U.S. Mail, four (4) Business Days after depositing in the United States mail, with postage prepaid and properly addressed.

The Loan Documents have been entered into pursuant to Section 5-1401 of the New York General Obligations Law and the substantive laws of the State of New York (except to the extent the laws of another jurisdiction govern the creation, perfection, validity, or enforcement of Liens under the Collateral Documents), and the applicable federal laws of the United States of America shall govern the validity, construction, enforcement and interpretation of the Loan Documents. 13.7 INVALID PROVISIONS. If any provision in any Loan Document is held to be illegal, invalid, or unenforceable, such provision shall be fully severable; the appropriate Loan Document shall be construed and enforced as if such provision had never comprised a part thereof; and the remaining provisions thereof shall remain in full force and effect and shall not be affected by such provision or by its severance therefrom. Administrative Agent, Lenders, and each Borrower party to such Loan Document agree to negotiate, in good faith, the terms of a replacement provision as similar to the severed provision as may be possible and be legal, valid, and enforceable. 13.8 ENTIRETY. THE RIGHTS AND OBLIGATIONS OF EACH BORROWER, LENDERS, AND ADMINISTRATIVE AGENT SHALL BE DETERMINED SOLELY FROM WRITTEN AGREEMENTS, DOCUMENTS, AND INSTRUMENTS, AND ANY PRIOR ORAL AGREEMENTS BETWEEN SUCH PARTIES ARE SUPERSEDED BY AND MERGED INTO SUCH WRITINGS. THIS AGREEMENT (AS AMENDED IN WRITING FROM TIME TO TIME) AND THE OTHER WRITTEN LOAN DOCUMENTS EXECUTED BY ANY LOAN PARTY, ANY LENDER, AND/OR ADMINISTRATIVE AGENT (TOGETHER WITH ALL COMMITMENT LETTERS AND FEE LETTERS AS THEY RELATE TO THE PAYMENT OF FEES AFTER THE CLOSING DATE) REPRESENT THE FINAL AGREEMENT BETWEEN THE LOAN PARTIES, LENDERS, AND ADMINISTRATIVE AGENT, AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS BY SUCH PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN SUCH PARTIES. 13.9 JURISDICTION; VENUE; SERVICE OF PROCESS; JURY TRIAL. EACH PARTY HERETO (INCLUDING EACH GUARANTOR BY EXECUTION OF A GUARANTY), IN EACH CASE FOR ITSELF, ITS SUCCESSORS AND ASSIGNS, HEREBY (A) IRREVOCABLY SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF THE STATE (PURSUANT TO SECTION 5-1402 OF THE NEW YORK GENERAL OBLIGATIONS LAW) AND FEDERAL COURTS LOCATED IN THE BOROUGH OF MANHATTAN IN THE STATE OF NEW YORK, AND AGREES AND CONSENTS THAT SERVICE OF PROCESS MAY BE MADE UPON IT IN ANY LEGAL PROCEEDING TERM LOAN AND SECURITY AGREEMENT 62

The Loan Parties and each other party to the Loan Documents acknowledge that this waiver is a material inducement to the agreement of each party hereto to enter into a business relationship, that each has already relied on this waiver in entering into the Loan Documents, and each will continue to rely on each of such waivers in related future dealings. The Loan Parties and each other party to the Loan Documents warrant and represent that they have reviewed these waivers with their legal counsel, and that they knowingly and voluntarily agree to each such waiver following consultation with legal counsel.

The Loan Documents may be executed in a number of identical counterparts, each of which shall be deemed an original for all purposes and all of which constitute, collectively, one agreement; but, in making proof of any Loan Document, it shall not be necessary to produce or account for more than one such counterpart. It is not necessary that each Lender execute the same counterpart so long as identical counterparts are executed by Borrower, each Lender, and each Co-Administrative Agent. This Agreement shall become effective when counterparts hereof shall have been executed and delivered to Administrative Agent by each Lender, Administrative Agent, and Borrower, or, when Administrative Agent shall have received telecopied, telexed, or other evidence satisfactory to it that such party has executed and is delivering to Administrative Agent a counterpart hereof. 13.12 SUCCESSORS AND ASSIGNS; ASSIGNMENTS AND PARTICIPATIONS. (a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns hereby, except that Borrower may not, assign or otherwise transfer any of its Rights or obligations hereunder without the prior written consent of each Lender.

(b) Any Lender may at any time assign to one or more Persons all or a portion of its Rights and obligations under this Agreement (including all or a portion of the Term Loan Principal Debt owing to it). The parties to each assignment by a Lender shall execute and deliver to Administrative Agent an Assignment and Assumption. (c) Any Lender may at any time, without the consent of, or notice to, Borrower or Administrative Agent, sell participations to any Person (other than a natural person or Borrower or any of Borrowers' Affiliates or Subsidiaries) (each, a "PARTICIPANT") in all or a portion of such Lender's Rights and/or obligations under this Agreement (including all or a portion of the Term Loan Principal Debt owing to it); provided that (i) such Lender's obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, and (iii) Borrower, Administrative Agent, and the other Lenders shall continue to deal solely and directly with such Lender in connection TERM LOAN AND SECURITY AGREEMENT 64
