WHEREAS, it is the goal of OVEC to assist its Sponsoring Companies by making available to them additional power and energy; and

WHEREAS, additional power would be made available as a result of reductions by DOE of its contractual entitlement to power from OVEC; and

WHEREAS, it was agreed between DOE and Corporation that DOE would reduce its contractual entitlement to OVEC power and energy in exchange for Corporation’s agreement to relieve DOE of certain costs associated with additional facilities and replacements (“AFR”); and

WHEREAS, it was necessary to allocate to the Sponsoring Companies shares of the AFR costs which, as a result of Corporation’s agreement with DOE, will no longer be payable by DOE; and

CHARGES FOR SURPLUS POWER AND ECAR EMERGENCY ENERGY, AND DOE SETTLEMENT SURCHARGES

6.01 Total Monthly Charge. The amount to be paid Corporation each month by the Sponsoring Companies for Surplus Power and Surplus Energy supplied under this Agreement shall consist of the sum of an energy charge, a demand charge and, if applicable, an emergency power surcharge, a DOE Settlement Capacity Surcharge and a DOE Settlement Energy Surcharge, all determined as set forth in this Article 6. The amount to be paid to Corporation for ECAR Emergency Energy supply under this Agreement shall be 98.74 mills per kilowatt hour (plus transmission charges calculated in accordance with applicable law).

5.             Delete subsection 6.024 and substitute therefor the following:

6.024 Determine for such month the difference between the total cost of fuel as described in subsection 6.021 above and the sum of (a) the total energy charge to be billed DOE as described in subsection 6.022 above, (b) the energy charge to be billed as DOE Emergency Energy as described in subsection 6.023 above and (c) the total cost of fuel used to generate ECAR Emergency Energy. For the purposes hereof the difference so determined shall be the fuel cost allocable for such month to the total kilowatt-hours of energy generated at the Project Generating Stations for the supply of Surplus Energy. For Surplus Energy made available to the Sponsoring Companies by the Letter Supplement between DOE and Corporation dated March 20, 2001 (the “Released Demand”), each Sponsoring Company shall pay Corporation for each such month an amount obtained by multiplying the ratio of the billing kilowatt-hours of such Surplus Energy availed of by such Sponsoring Company during such month to the aggregate of the billing kilowatt-hours of all Surplus Energy availed of by all Sponsoring Companies during such month times the difference determined hereinabove. For all other Surplus Energy, each Sponsoring Company shall pay Corporation an amount equal to (i) an amount obtained by multiplying the billing

5

kilowatt-hours of Surplus Energy (other than Surplus Energy associated with the Released Demand) availed of by such Sponsoring Company during such month by the average station heat rate of the Project Generating Stations times the average cost per Btu (determined in a uniform manner for all Sponsoring Companies in conformity with any applicable requirements of Account 703 (Fuel) of the Uniform System of Accounts) of all fuel consumed by said Sponsoring Company in its own generating stations, both averages to be computed in respect of the month next preceding that for which payment is being made, plus (ii) its Power Participation Ratio of the excess, if any, for such month of the fuel costs of the Corporation allocable to the total kilowatt-hours of energy generated at the Project Generating Stations for the supply of Surplus Energy (other than Surplus Energy associated with the Released Demand) over the aggregate of the amounts computed with respect to all Sponsoring Companies under (i) above, minus (iii) its Power Participation Ratio of the excess, if any, for such month of the aggregate of the amounts computed with respect to all Sponsoring Companies under (i) above over the fuel costs of the Corporation allocable to the total kilowatt-hours of energy generated at the Project Generating Stations for the supply of Surplus Energy (other than Surplus Energy associated with the Released Demand).

8.           Delete subsection 6.033 and substitute therefor the following:

6.033 Determine the demand charge to be charged to DOE for such month, such demand charge to be an amount equal to the product of the aggregate of the costs determined in accordance with subsection 6.031 above and the average DOE capacity ratio in effect for such month, weighted with respect to the periods of time during which DOE capacity ratios were in effect; provided, however, that the demand charge to be charged to DOE for such month shall be reduced by amounts, if any, specified in paragraph 3 of Section 3.04 of the DOE Power Agreement with respect to fines and penalties, which amounts DOE shall not be obligated to pay to Corporation as a result of the second proviso contained in Section 7.05 of the DOE Power Agreement and other amounts, if any, specified in paragraph 3 of Section 3.04 of the DOE Power Agreement which DOE shall not be obligated to pay to Corporation as a result of adjustments mutually agreed upon by Corporation and DOE pursuant to said second proviso which reads as follows:

7

determined as provided in clause (ii) above plus transmission losses thereon, then the amount to be paid by DOE to Corporation on account of the costs specified in paragraph 3 of Section 3.04 other than (a) any interest, principal, and/or amortization component of any purchase price, amortization, rental, or other payment under an installment sale, loan, lease or similar agreement relating to the purchase, lease, or acquisition by Corporation of additional facilities under Section 3.06 and replacements under Section 3.07, (b) the cost of any insurance carried solely for the benefit of DOE at its request pursuant to paragraph 3(b) of Section 3.04 and (c) any taxes allocated directly to DOE pursuant to paragraph 3(c) of Section 3.04, shall be adjusted to the extent mutually agreed upon);...”
