The Availability Agreement provided assurances that the Company had available adequate cash resources to cover its operating expenses and interest costs and permanent shutdown costs in the event of a shortfall of funds available to the Company from sales of power and energy under the UPSA. Such adequate cash resources were assured under the Availability Agreement by individually obligating the Affiliate Operating Companies to make payments or subordinated advances to the Company in accordance with stated percentages for each Affiliate Operating Company. Since commercial operation of Grand Gulf began, no payments under the Availability Agreement by the Affiliate Operating Companies have ever been required.

The Company, the Mortgage Trustee, the MBFC Indenture Trustee (in the case of the Thirty-ninth Assignment of Availability Agreement) and the Affiliate Operating Companies subsequently entered into each Assignment of Availability Agreement whereby the Company assigned its rights under the Availability Agreement as additional security for the respective series of Bonds and for the MBFC Bonds (in the case of the Thirty-ninth Assignment of Availability Agreement).

All conditions have been satisfied. As a result of the termination of the Availability Agreement and the Assignments of Availability Agreement, neither the Bonds nor the MBFC Bonds is entitled to the security provided by the Availability Agreement and the respective Assignment of Availability Agreement.

Entry into 2025 Availability Agreement and Assignments of 2025 Availability Agreement

Immediately following the above-described termination of the Availability Agreement and the Assignments of Availability Agreement and effective as of October 1, 2025, the Company entered into a new availability agreement (the “2025 Availability Agreement”) between the Company and the 2025 Affiliate Operating Companies. The 2025 Availability Agreement provides assurances that the Company has available adequate cash resources to cover its operating expenses and interest costs and permanent shutdown costs in the event of a shortfall of funds available to the Company from sales of capacity and energy under the 2025 UPSA and from other sources.

Pursuant to the terms of the 2025 Availability Agreement, so long as at least one 2025 Affiliate Operating Company remains a party to the 2025 Availability Agreement, any other 2025 Affiliate Operating Company may assign all or part of its rights and obligations thereunder to any other 2025 Affiliate Operating Company, and such assigning 2025 Affiliate Operating Company shall be discharged of its obligations under the 2025 Availability Agreement upon the assumption of such obligations by the remaining 2025 Affiliate Operating Company or Companies.

Pursuant to the terms of the Assignments of 2025 Availability Agreement, subject to the delivery of certain documents, any 2025 Affiliate Operating Company may assign to one or more other 2025 Affiliate Operating Companies its obligations and liabilities under the 2025 Availability Agreement and the Assignments of 2025 Availability Agreement.
