The third sentence of Section 9.02 is hereby deleted and replaced by the following: The quality of electricity delivered shall be at least equal to the Quality of Electricity Criteria set forth in Exhibit T. 9. The following sentence is hereby inserted between the first and second sentences of Section 9.06(a): With regard to Independence's obligations pursuant to the preceding sentence, at Alcan's request, Independence will install, at its sole cost, any additional systems or equipment reasonably required to ensure a maximum of one hour switch-over time to back-up or standby electricity as soon as reasonably possible after the first incident where a period of more than one hour was required for such switch-over. 10. The second sentence of Section 9.06(c) is hereby deleted and replaced by the following: If there are more than two interruptions of electrical service from the Project during any three month period, or if there are more than two interruptions of Alcan process equipment during any three month period caused solely by the supply of electricity which does not meet the Quality of Electricity criteria, upon the 8 occurrence of the third (or more) interruption Alcan shall have the option to elect or remain on back-up or standby service, at Independence's expense, until Independence can demonstrate to Alcan's reasonable satisfaction that the cause (or causes) of the interruptions has been cured provided, however, that Independence must cure the cause (or causes) of the interruptions within a reasonable time. 11. The following new Section 9.06(d) is hereby inserted following Section 9.06(c): 9.06 (d) With respect to Section 9.06(c) hereof, Alcan acknowledges that its process equipment may be affected by operating problems and interruptions which are not caused by the quality of electricity it receives and that Independence is not in a position to understand the nature or causes of such problems and interruptions. Accordingly, if any such problems or interruptions occur which Alcan reasonably believes are caused solely by Independence's failure to provide electricity which meets or exceeds the Quality of Electricity criteria, Alcan will work with Independence to confirm and demonstrate to Independence that any such problem or interruption was so caused and is, therefore, subject to the second sentence of Section 9.06(c) hereof. 12.

Sithe/Independence has installed two air handling units originally planned for Alcan's Oswego Works into Alcan's new recycling facility. 2. The aggregate annual quantities of thermal energy to be consumed by Alcan will equal or exceed the aggregate annual quantities of thermal energy that Alcan would have consumed had the two air handling units been installed as originally 10 contemplated at Alcan's existing facilities. The other provisions of the Energy Sales Contract with respect to Alcan's thermal usage obligations shall apply. (b) Supply of Electricity to Recycling Facility 1. Alcan will utilize a portion of the Alcan Capacity Entitlement, as that term is defined in the Energy Sales Contract, to supply its additional electrical needs at the new recycling facility and Sithe/Independence shall supply such electricity to Alcan pursuant to the terms of the Energy Sales Contract provided, however, that Sithe/Independence will provide a discount for a portion of the actual additional electrical usage (not to exceed (i) a maximum demand of 3 MW in any hour or (ii) 26,280,000 kilowatthours in any twelve month period) at the new recycling facility for a period of three years from January 1, 1996. It is the intent of Alcan and Sithe/Independence that none of the electric energy purchased by Alcan for use at Alcan's facilities (other than at the new recycling facility) will be eligible for any discount hereunder nor will any electric energy associated with a demand at the new recycling facility in excess of 3 MW be eligible for any discount hereunder. The price to be paid during the three year period of discounts for such portion of the actual electrical usage at the new recycling facility eligible for a discount shall be $.036/kwh. Such discount will be subject to the following conditions: (i) Alcan will be responsible for the cost of installation of any electrical distribution systems or any related facilities necessary for the interconnection of the electrical system of the new recycling facility with the existing electrical distribution system, provided that Sithe/Independence may install additional electrical metering if 11 reasonably required to measure the actual usage at the new recycling facility (ii) Alcan and Sithe/Independence will work together to minimize such costs and agree that billing quality meters will not be required given that the discount for services at the recycling facility will remain in effect for only three years. (iii) Alcan will provide Sithe/Independence with reasonable access to all of the metering data and information collected by the electrical metering installed by Alcan at the new recycling facility as well as any other data or information reasonably requested by Sithe/Independence to verify that the discount provided hereunder is being applied only to the electrical energy utilized at the new recycling facility and only to the extent that such electrical energy is associated with a demand at the new recycling facility of 3 MW or less. 12 IN WITNESS WHEREOF, Independence and Alcan have caused this Amendment No. 2 to be executed by their proper, duly authorized officers SITHE/INDEPENDENCE POWER PARTNERS, L.P.
