WITNESSETH WHEREAS, pursuant to the Power Contract, Vermont Yankee supplies to the Purchaser and, pursuant to separate power contracts substantially identical to the Power Contract except for the names of the parties, to the other Sponsors of Vermont Yankee, each of whom is contemporaneously entering into an amendment to its power contract which is identical hereto except for the necessary changes in the names of the parties, all of the capacity and the electric energy available from the nuclear generating unit owned by Vermont Yankee at a site adjacent to the Connecticut River at Vernon, Vermont (such unit being herein together with the site and all related facilities owned by Vermont Yankee, referred to as the "Unit"). WHEREAS, Vermont Yankee, the Purchaser and the other Sponsors of Vermont Yankee believe that the monthly payments provided in the Power Contracts are no longer sufficient to provide a return on the equity investment in the Unit which is equal to the return achieved on investments of comparable risk. WHEREAS, in order to assure the maintenance of an appropriate level of return on common equity, Vermont Yankee and the Purchaser have agreed to enter into this Agreement. NOW, THEREFORE, in consideration of the above and of other good and valuable consideration, receipt of which is hereby acknowledged, the parties hereto agree that the Power Contract is hereby amended as follows: 1. Terms used herein and not defined shall have the meanings set forth in the Power Contract. 2.

This Agreement shall become effective on May 14, 1985, or upon such later date as it shall be permitted to become effective by the Federal Energy Regulatory Commission or other governmental regulatory authority having jurisdiction. The Agreement may be executed in any number of counterparts and each executed counterpart shall have the same force and effect as an original instrument and as if both parties to all of the counterparts had signed the same instrument.
