Promptly after the Satisfaction Date, as defined in Section 4 of Amendment No. 4, any capacity payments previously made by Edison to Seller for deliveries made on and after December 1, 2002 which were based upon the capacity price in effect prior to the occurrence of the Satisfaction Date shall be recalculated using the capacity price as revised pursuant to the foregoing Section 9.1.1.1(c). The difference (without interest) between the capacity payment(s) actually made for such deliveries and the payments that would have been made using the adjusted capacity price specified in Section 9.1.1.1(c) shall be applied as a credit to Edison against the next payment due to Seller for both Energy and capacity pursuant to the Contract; provided, however, that if the amount of such credit to Edison exceeds the full amount owing for the first payment due to Seller after the Satisfaction Date, Edison shall take a credit equal to the full amount owing for the first payment due Seller after the Satisfaction Date, and shall apply the remaining balance of the credit as an offset to each successive payment due to Seller by Edison thereafter in the same manner until the credit is fully utilized (all such offsets accruing as of the Satisfaction Date).
