1 EXHIBIT 10.68 SUBORDINATION AGREEMENT This Subordination Agreement (this "Agreement") is made as of February 7, 2001, by Firstar Bank, N.A. as Trustee under the Indenture referred to below (in such capacity, herein called the "Mortgage Holder") and TransTexas Gas Corporation, a Delaware corporation (herein called "TransTexas") for the benefit of Mirant Americas Energy Capital, LP, formerly named Southern Producer Services, L.P., and TCW DR VI Investment Partnership, L.P. (herein collectively called the "Production Payment Owners"). RECITALS: 1. The Mortgage Holder and TransTexas have entered into that certain Indenture dated as of March 15, 2000 (herein, as from time to time amended or supplemented, called the "Indenture"), for the equal and ratable benefit of the holders of TransTexas's Senior Secured Notes due 2005. Pursuant to the Indenture, TransTexas has executed and delivered certain mortgages, deeds of trust, security agreements and financing statements (collectively, the "Security Documents") to secure such Notes. A true and complete list of such Security Documents which burden properties in Texas is attached as Schedule 1 hereto and made a part hereof. Each deed of trust and mortgage listed on Schedule 1 is herein called a "Mortgage". 2. As described in Section 9.2 of each Mortgage, TransTexas has heretofore executed and delivered to the Production Payment Owners that certain Production Payment Conveyance made effective as of 9:00 a.m., Houston, Texas time on March 1, 2000 (defined in each such Section 9.2 as the "Production Payment Conveyance" and herein called the "Original Conveyance"), pursuant to which TransTexas conveyed and assigned to the Production Payment Owners a certain production payment (defined in each such Section 9.2 as the "Production Payment" and herein called the "Original Production Payment"). As described in Section 9.2 of each Mortgage, the Original Conveyance was given pursuant to an Order of the United States Bankruptcy Court. As contemplated in such Court Order, the Original Conveyance has heretofore been supplemented by a First Supplement to Production Payment Conveyance dated as of June 7, 2000 (the "First Supplement"), by a Second Supplement to Production Payment Conveyance dated as of September 8, 2000 (the "Second Supplement"), and by a Third Supplement to Production Payment Conveyance dated as of November 7, 2000 (the "Third Supplement"), to increase the unliquidated balance of the "Primary Sum" thereunder. The Original Conveyance, the First Supplement, the Second Supplement, and the Third Supplement have been recorded as set forth in Schedule 1 to Exhibit A hereto. 3. Concurrently herewith, in consideration of funds to be paid to TransTexas, TransTexas and the Production Payment Owners are executing and delivering that certain Fourth Supplement to Production Payment Conveyance of even date herewith (the "Fourth Supplement") which further supplements and amends the Original Conveyance. Prior to the effective time of the Fourth Supplement, one of the three original owners of the Production Payment (TCW Portfolio No. 1555 DR V Sub-Custody Partnership, L.P.) is conveying all of its interests in the Production Payment to Mirant Americas Energy Capital, LP, formerly named 2 Southern Producer Services, L.P., one of the two remaining Production Payment Owners, and after the effective time of the Fourth Supplement, Mirant Americas Energy Capital, LP, formerly named Southern Producer Services, L.P., is conveying part of its interests in the Production Payment to TCW DR VI Investment Partnership, L.P., the other remaining Production Payment Owner. True and correct copies of both such conveyances, and a true and correct copy of the Fourth Supplement, are attached hereto as Exhibit A-1, Exhibit A-2 and Exhibit A-3, respectively, and each is hereby made a part hereof. As used herein, "Conveyance" means the Original Conveyance as amended and supplemented by the First Supplement, the Second Supplement, the Third Supplement, the Fourth Supplement, and such conveyances, and "Production Payment" has the meaning given to such term in the Conveyance. 4. Under the Indenture, the Production Payment constitutes "First Lien Debt" secured by a "Permitted Lien" (as such terms are defined in the Indenture). Pursuant to Section 11.2(c) of the Indenture, TransTexas has delivered a "Subordination Request" to the Mortgage Holder, asking the Mortgage Holder to enter into this Agreement in order to subordinate the Mortgage Holder Liens to the Production Payment and the Conveyance (after taking the Fourth Supplement into account), and TransTexas has satisfied the conditions in such Section 11.2(c). (As used herein, "Mortgage Holder Liens" means all liens, security interests, assignments (of production or otherwise) and other rights or interests of the Mortgage Holder at any time existing on or in any properties or assets of TransTexas which are in any way subject to the Production Payment or the Conveyance, whether such liens, security interests, assignments and other rights or interests arise under the Indenture or the Security Documents or by operation of law or otherwise.) NOW, THEREFORE, in consideration of the foregoing, and in order to induce the Production Payment Owners to enter into the Fourth Supplement and pay funds to TransTexas in connection therewith, the Mortgage Holder and TransTexas hereby agree as follows: Section 1. Subordination. The Production Payment and the proceeds thereof are and hereafter shall be senior in right and priority to all Mortgage Holder Liens, regardless of the relative priority of the Mortgage Holder Liens and the Production Payment as determined without regard to this Agreement, and the same shall have the same validity and effect as if the Conveyance (including all supplements thereto) had been executed, delivered and properly recorded prior to the date and time of execution of the Indenture and the date and time of execution and recordation of the Security Documents. All references in Section 9.2 of each Mortgage to the "Production Payment Conveyance" shall hereafter refer to the Conveyance, as defined herein, and all references in Section 9.2 of each Mortgage to the "Production Payment Conveyance" shall henceforth refer to the Production Payment Conveyance, as defined herein. As so modified, the terms of Section 9.2 of each Mortgage are hereby ratified and confirmed. Section 2. Acknowledgment of Reliance. The parties acknowledge and agree that Production Payment Owners have entered into the Fourth Supplement in reliance on the priority of the Conveyance, and thus are relying on the waiver, relinquishment and subordination set forth herein. 2 3 Section 3. Governing Law. This Agreement shall be deemed a contract and instrument made under the laws of the State of Texas and shall be construed and enforced in accordance with and governed by the laws of such state and the laws of the United States of America, without regard to principles of conflicts of law. Section 4. Invalidity of Particular Provisions. If any term or provision of this Agreement shall be determined to be illegal or unenforceable, all other terms and provisions hereof shall nevertheless remain effective and shall be enforced to the fullest extent permitted by applicable law. Section 5. Successors and Assigns. This Agreement shall pass to and be fully binding upon and inure to the benefit of the successors and assigns of each party hereto (including the Production Payment Owners). Section 6. Counterparts. This Agreement may be separately executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to constitute one and the same instrument. IN WITNESS WHEREOF, this Agreement is executed by the parties hereto on the dates set out below in their respective acknowledgments, to take effect as of the date first above written.
