AGE = [(SUPO) x (OMF) x (OMAG)] + [(SUPO) x (1-OMF) x (CFAG)] where: AGE = Monthly start-up and pre-operation administrative and general expenses for each Generating Unit. SUPO = Monthly Start-Up and Pre-Operation Costs for each Generating Unit. OMF = Percent (expressed as a decimal) of the total monthly Start-Up and Pre-Operation Costs for each Generating Unit to be allocated to the operation and maintenance administrative and general expense formula, as determined in Section L.1.3. OMAG = Operation and maintenance administrative and general expense percentages as determined and applied in Sections E.1.7 and E.1.9 of the Participation Agreement. L-1 CFAG = Construction administrative and general expense percentage of one percent (1%) as applied pursuant to Section D.1.14 of the Agreement. L.1.2 Start-Up and Pre-Operation Costs for ANPP common facilities shall be allocated by apportioning one-third (1/3) of these expenses to each ANPP Generating Unit prior to determining the administrative and general expense associated with each Generating Unit. L.1.3 To determine start-up and pre-operation administrative and general expense (AGE) in Section L.1.1 the monthly total Start-Up and Pre-Operation Costs for each ANPP Generating Unit, including its common facilities share, shall be allocated between construction and operation & maintenance in accordance with the benchmark time period begins in the middle of a month, the change in percentage allocation to construction and operation & maintenance expenses shall take place on the first day of the calendar month following such benchmark.

Satisfactory completion of 100% O&M Power Ascension Level 50% to completion of start-up and pre-operation. L.2 Adjustments L.2.1 The benchmark time periods in Items L.1.3a and L.1.3b require an estimate of the Beginning of Generating Unit Precore Hot Functional Test for a Generating Unit. Should the actual date for the Beginning of Generating Unit Precore Hot Functional Test for a Generating Unit be different than estimated, adjustments shall be made to the amount of administrative and general expense actually charged based on the appropriate allocation of Start-Up and Pre-Operation Costs to construction and operation & maintenance expenses. L-3 L.2.2 Amounts of administrative and general expense determined pursuant to the Letter of Understanding for the period October 1, 1984 through March, 1985 that were different than the amount actually paid for the same period have, pursuant to the Letter of Understanding appeared as a credit on the request for advancement of Operating Funds for ANPP dated June 14, 1985, Request No. PVO-093. Such expense differences accrued interest at the rate from time to time publicly announced by Citibank, N. A., New York, New York, as its prime interest rate less two percent (2%), from the date of payment of such difference to the date of mailing of the request for advancement of Operating Funds. Any such amounts were allocated to each Participant in accordance with its Generation Entitlement Share, and were clearly delineated on the Operating Agent's requests for advancement of Operating Funds. L.3 Credit to Future Requests for Advancement of Operating Funds for ANPP L.3.1 The Operating Agent shall credit to future requests for advancement of Operating Funds, thirteen million dollars (13,000,000) plus interest, determined pursuant to Section L.3.2 of this Appendix L, for administrative and general expense charged to Start-Up and Pre-Operation Costs through L-4 September 30, 1984. Such credit will be allocated to each Participant in accordance with its Generation Entitlement Share, and is separate and in addition to any adjustment to administrative and general expense necessitated by the routine annual adjustment to the Operation and Maintenance A & G Ratio pursuant to Section E.10.2 of the Participation Agreement. No other adjustments shall be made to change administrative and general expense charged to Start-Up and Pre-Operation Costs through September 30, 1984, except for those related to any future adjustments made to Start-Up and Pre-Operation Costs incurred through such date. L.3.2 Interest will be charged on the unpaid balance of the thirteen million dollars ($13,000,000) credit beginning on October 1, 1984. The interest rate to be applied will be the rate from time to time publicly announced by Citibank, N.A., New York, New York, as its prime interest rate, less two percent (2%). The initial credit shall include all interest accrued from September 30, 1984, and subsequent monthly credits will be applied first against accrued interest. In addition to such monthly payments of all accrued interest, the principal balance shall be amortized by crediting monthly an amount equal to not less than one twenty-fourth (1/24) of such amount L-5 until the full thirteen million dollars ($13,000,000) principal amount has been credited.
