If and when the DWR is no longer responsible for the payment of costs under any Power Supply Contracts, all excess amounts in the Operating Account shall be utilized in the same fashion as Excess Amounts as set forth in Section 3 of this Addendum to Summary of Material Terms, provided that, the Operating Account may remain open to pay those administrative expenses that would otherwise have to be paid out of Bond Charge Revenues as described in Section III of the Summary of Material Terms. If the Operating Account is held open for the purpose of paying these administrative expenses after DWR is no longer selling power, all amounts not needed to pay such administrative expenses shall be treated as Excess Amounts.
