                    1.3  Payments to the Corporate Trustee. The Company agrees that, if and whenever it shall make a demand to a System Operating Company for any payment pursuant to Section 4 of the Availability Agreement or advances pursuant to Section 2.2(b) hereof with respect to Unit No. 1 or Unit No. 2, it will separately identify the respective portions of such payment or advance, if any, required for (i) the payment of Obligations Secured Hereby and (ii) the payment of any other amounts then due and payable in respect of Additional Indebtedness and instruct such System Operating Company (subject to the provisions of Section 1.4 hereof) to pay or cause to be paid the amount so identified as required for the payment of Obligations Secured Hereby directly to the Corporate Trustee. Any payments made by any System Operating Company pursuant to Section 4 of the Availability Agreement or advances pursuant to Section 2.2(b) hereof with respect to Unit No. 1 or Unit No. 2 shall, to the extent necessary to satisfy in full the assignment set forth in Section 1.1 of this Assignment and the corresponding assignments set forth in the Additional Assignments, be made pro rata in proportion to the respective amounts secured by, and then due and owing under, such assignments.

If the Corporate Trustee shall have duly notified the System Operating Companies of the occurrence of any such Default, such payments or advances shall be made in the manner and in the amounts specified in Section 1.3 hereof until the Corporate Trustee shall by further notice to the System Operating Companies give permission that all such payments or advances may be made again to the Company, such permission being subject to revocation by a subsequent notice pursuant to the first sentence of this Section 1.4. The Corporate Trustee shall give such permission if no such Default continues to exist.

ARTICLE II.

Consent to Assignment by the System Operating

                   2.1  Consent to Assignment by the System Operating Companies.

                   2.2  Other Agreements. Anything in the Availability Agreement to the contrary notwithstanding, it is hereby agreed as follows:

                   (a)  Regardless of whether any person or persons (other than the System Operating Companies) shall become a Party or Parties (as such terms are defined in the Availability Agreement) to the Availability Agreement, the System Operating Companies shall at all times be obligated to make the payments required pursuant to Section 4 of the Availability Agreement and to make advances pursuant to Section 2.2(b) hereof with respect to Unit No. 1 and Unit No. 2 to the same extent as if the System Operating Companies were the only Parties to the Availability Agreement, except to the extent and only to the extent that such payments or advances are actually made by such person or persons. In the event that any such person shall become a Party to the Availability Agreement, the Company and the System Operating Companies shall cause such person, at the time when such person becomes a Party to the Availability Agreement, to consent by written instrument to the terms and provisions of this Assignment, and thereupon such person shall be bound by all of the terms and provisions of this Assignment (other than the provisions of the preceding sentence) to the same extent as if named a System Operating Company herein.

                   (b)  In the event and to the extent that any action by any governmental regulatory authority, including, without limitation, the Federal Energy Regulatory Commission or any successor thereto, shall have the effect of prohibiting the System Operating Companies from making any payments which would otherwise be required pursuant to Section 4 of the Availability Agreement (as supplemented hereby) with respect to Unit No. 1 and Unit No. 2, the System Operating Companies shall make advances to the Company at the same time, and in the same amounts as such prohibited payments and all such advances shall constitute Subordinated Indebtedness of the Company.

                   (c)  Each System Operating Company agrees that (i) all Indebtedness for Borrowed Money of the Company to such System Operating Company and all amounts paid by such System Operating Company pursuant to Section 4 of the Availability Agreement or advanced pursuant to Section 2.2(b) hereof shall constitute Subordinated Indebtedness of the Company and (ii) no such Subordinated Indebtedness of the Company shall be transferred or assigned (including by way of security) to any person (other than to a successor of such System Operating Company by way of merger, consolidation or the acquisition by such person of all or substantially all of such System Operating Company's assets). The Company agrees that it shall duly record all Subordinated Indebtedness of the Company as such on its books.

                   (e)  In the event that Entergy shall cease to own a majority of the common stock of any System Operating Company, the obligations of such System Operating Company hereunder and under the Availability Agreement shall not be increased by an amendment to or modification of the terms and provisions of the Indenture, the Twenty-third Supplemental Indenture or the Twenty-first Series Bonds unless such System Operating Company shall have consented in writing to such amendment or modification.

                   (f)  The obligations of each System Operating Company under Section 4 of the Availability Agreement and Section 2.2(b) hereof to make the payments or advances specified therein or herein with respect to Unit No. 1 and Unit No. 2 to the Company shall not be subject to any abatement, reduction, limitation, impairment, termination, set-off, defense, counterclaim or recoupment whatsoever or any right to any thereof (including, but not limited to, abatements, reductions, limitations, impairments, terminations, set-offs, defenses, counterclaims and recoupments for or on account of any past, present or future indebtedness of the Company to such System Operating Company or any claim by such System Operating Company against the Company, whether or not arising hereunder, under the Availability Agreement or under the System Agreement and whether or not arising out of any action or nonaction on the part of the Company or the Trustees (or either of them), including any disposition of the Project or any part thereof pursuant to the Indenture, requirements of governmental authorities, actions of judicial receivers or trustees or otherwise and whether or not arising from willful or negligent acts or omissions). The foregoing, however, shall not, subject to the provisions of paragraph (c) of this Section 2.2, affect in any other way any rights and remedies of such System Operating Company with respect to any amounts owed to such System Operating Company by the Company or any such claim by such System Operating Company against the Company. The obligations and liabilities of each System Operating Company hereunder or under the Availability Agreement shall not be released, discharged or in any way affected by any reorganization, arrangement, compromise, composition or plan affecting the Company or any change, waiver, extension, indulgence or other action or omission in respect of any indebtedness or obligation of the Company or such System Operating Company, whether or not the Company or such System Operating Company shall have had any notice or knowledge of any of the foregoing. Neither failure nor delay by the Company or the Trustees (or either of them), or any holder, or representative of any holder of the Twenty-first Series Bonds to exercise any right or remedy provided herein or by statute or at law or in equity shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or remedy preclude any other or further exercise thereof, or the exercise of any other right or remedy. Each System Operating Company also hereby irrevocably waives, to the extent that it may do so under applicable law, any defense based on the adequacy of a remedy at law which may be asserted as a bar to the remedy of specific performance in any action brought against such System Operating Company for specific performance of this Assignment or the Availability Agreement by the Company, by the Trustees (or either of them), by the holders of the Twenty-first Series Bonds or for their benefit by a receiver or trustee appointed for the Company or in respect of all or a substantial part of the Company's assets under the bankruptcy or insolvency law of any jurisdiction to which the Company is or its assets are subject. Anything in this Section 2.2(f) to the contrary notwithstanding, no System Operating Company shall be precluded from asserting as a defense against any claim made against such System Operating Company upon any of its obligations hereunder and under the Availability Agreement that it has fully performed such obligations in accordance with the terms of this Assignment and the Availability Agreement.

                   (g)  Each System Operating Company shall, subject to the provisions of Section 2.2(c) hereof, be proportionately subrogated to all rights of the Trustees and the holders of the Twenty-first Series Bonds against the Company in respect of any amounts paid or advanced by such System Operating Company pursuant to the provisions of this Assignment and the Availability Agreement and applied to the payment of the Obligations Secured Hereby. The Trustees agree that they will not deal with the Company, or any security for the Twenty-first Series Bonds in such a manner as to prejudice such rights of any System Operating Company.

It is agreed that all the covenants and undertakings on the part of the System Operating Companies and the Company set forth in this Assignment are exclusively for the benefit of, and may be enforced only by, the Trustees (or either of them), by the holders of the Twenty-first Series Bonds as provided in the Indenture, or for their benefit by a receiver or trustee for the Company or in respect of all or a substantial part of its assets under the bankruptcy or insolvency law of any jurisdiction to which the Company is or its assets are subject.

Nothing in this Assignment shall affect any right or remedy of the Company or any System Operating Company against the Trustees (or either of them) (other than those specifically waived herein), for breach or violation of any of the obligations or duties of the Trustees assumed or undertaken in this Assignment. Without limiting the generality of the foregoing, the Trustees (and each of them) assume no responsibility as to the validity or enforceability hereof or for the correctness of the recitals of fact contained herein or in the Availability Agreement, which shall be taken as the statements, representations and warranties of the Company and the System Operating Companies.
