Quantity: O'Brien agrees to sell electricity to Du Pont for use in Du Pont's Plant in quantities required by Du Pont up to a maximum of 9MW and Du Pont agrees to buy its purchase requirements for electricity up to 9MW in accordance with the terms and conditions hereof for a twenty (20) year period commencing with the Initial Delivery Date. If Du Pont should require more than 9M, O'Brien will supply the additional requirements on such terms and conditions as the parties shall agree at the time, but under no circumstances will the price be greater and the terms more stringent than those covering the initial 9MW under this agreement. B. Type and Character of Service: The electrical energy furnished by O'Brien shall be of the type known as t twenty four hundred (2400) volts, three (3) phase, three (3)( wire, sixty (60) cycles, alternating current. he variation of the voltage shall remain within plus or minus 5% of 2400 volts. 2 C. Description of the System: All equipment (except the 2.4kv switchgear and feeders) will be owned, operated and maintained by O'Brien.

ARTICLE V. Construction and Operation of the Cogeneration Facility. A. O'Brien has agreed in the Steam Purchase Contract to construct and operate the Facility to furnish steam to Du Pont. In addition to the commitments made in that document, O'Brien agrees to the further provisions in this Article V to allow O'Brien to supply Du Pont with the electricity covered buy this Electricity Purchase Agreement. B. O'Brien agrees to construct the facility with a capacity adequate to deliver at least 9MW of electricity to D Pont on a continuous basis. To ensure this capacity, O'Brien will install two Frame Six Combustion Turbine Combined Cycle Systems, each of which is more than capable of meeting Du Pont's projected demand. C. In the event O'Brien fails to supply Du Pont's electricity requirements for a period of six consecutive months or, in the alternative, if O'Brien notifies Du Pont that it can no longer meet such requirements, O'Brien will immediately make available to du Pont for Du Pont's use all equipment necessary to serve Du Pont from the 230kv system until Du Pont's service can be returned to the 34.5kv system or Du Pont finds other electric service acceptable to Du Pont. 4 O'Brien shall obtain in its loan agreement any necessary waiver from its lender to permit Du Pont to exercise the foregoing option. Furthermore, the two 13.8kv to 2.4kv transformers shall be installed in such a way that they can be replaced with 34.5kv to 2.4kv transformers and reconnected to the existing JCP&L 34.5kv feeders. To the extent JCP&L requires Du Pont to pay for this conversion, O'Brien agrees to contribute up to $ 500,000 toward the cost of such conversion and will secure such obligation by establishing at the time the cogen facility starts up either an escrow account or a letter of credit with a credit worthy bank in the amount of $500,000.

O'Brien will be responsible for maintenance of all equipment and systems above the Point of Interconnection, and Du Pont will be responsible for maintenance of all equipment and systems below the Point of Interconnection., B. The interconnection facilities shall be designed to generally accepted engineering standards. Du Pont and O'Brien agree to cooperate in determining appropriate and compatible equipment specifications for interconnection 5 facilities; provided, however, that notwithstanding anything to the contrary herein, Du Pont shall not be responsible for any damage to the Facility due to demand from Du Pont's systems. O'Brien will give Du Pont at least forty-five days notice prior to commencing operation and interconnection. Du Pont and O'Brien shall develop written procedures for interconnection, prior to interconnection. Du Pont shall have the right to witness testing and start up of all interconnection facilities. C. O'Brien shall at its expense, and in accordance with Exhibit B, dismantle and remove, including transportation to JCP&L's facilities for storage or disposal in accordance with appropriate regulations, JCP&L's existing 34.5kv substations and transmission lines, and the 2.4kv metering installations from the Parlin Site. D. The existing 34.5kv feeders supplying the Du Pont plant shall be maintained in operation throughout the construction of the Facility. Shutdowns during feeder relocations should be limited to one feeder at a time and to a maximum duration of twelve (12) hours for any one shutdown. Switchover from the JCP&L a34.5 feeders to O'Brien's 13.8kv feeders shall not be made until O'Brien's generating facility is fully on line and has demonstrated for a sixty (60) day period a 100% ability to meet Du Pont's electric requirements. ARTICLE VII. Service Interruptions A. Subject to force majeure and normal maintenance requirements, O'Brien agrees to provide a continuous supply 6 of electricity to Du Pont at the quantities and characteristics described in Article II hereof. B.

Such termination shall not affect Du Pont's right or O'Brien's obligation to continue the electrical interconnection parts of this contract, and O'Brien will take all reasonable steps to assure uninterrupted electrical service from JCP&L to Du Pont. D. If JCP&L's tariffs or the rules of the New Jersey Board of Public Utilities change so that Du Pont cannot 8 receive the equivalent of firm power without signing a new contract with JCP&L, Du Pont shall have the right to reduce purchases from O'Brien to the e extent power is purchased from JCP&L under such new contract. ARTICLE X. Metering A. O'Brien will own, operate, and maintain all necessary meters and associated equipment, including, without limitation, generation metering and the telemetering equipment, utilized for measuring energy deliveries and for determining Du Pont's payments to O'Brien.
