ASRP 4.3 SC'S OBLIGATION FOR REGULATION

                Each Scheduling Coordinator's Obligation for Regulation for each
                Settlement Period of the Day-Ahead Market and for each
                Hour-Ahead Market in each Zone shall be calculated based upon
                the ratio of Demand scheduled by each Scheduling Coordinator in
                each identified Zone for that Settlement Period to the total
                Scheduled Demand for that Settlement Period in that Zone.


ASRP 5.5.1 OBLIGATION FOR SPINNING AND NON-SPINNING RESERVE

                Except for the requirement for Non-Spinning Reserve referred to
                in paragraph ASRP 5.5.2, the Spinning and Non-Spinning Reserve
                allocation for each Settlement Period of the Day-Ahead Market
                and for each Hour-Ahead Market shall be determined for each
                Scheduling Coordinator equal to 5% of its pro rata share of the
                total system Demand (except the Demand covered by firm purchases
                from outside the ISO Control Area) scheduled to be met by total
                system Generation from hydroelectric resources plus 7% of its
                pro rata share of the total system Demand (except the Demand
                covered by firm purchases from outside the ISO Control Area) to
                be met by total system Generation from non-hydroelectric
                resources. This obligation will originally be determined without
                the consideration of Congestion, however the final allocation
                may be made by the ISO to each Scheduling Coordinator in such a
                manner as to minimize Congestion.


ASPR 6.1.2 REPLACEMENT RESERVE REQUIREMENTS

                The ISO shall have discretion to determine the quantity of
                Replacement Reserve it requires in each Zone. The ISO shall make
                its determination of the required quantity of Replacement
                Reserve based on:

                (a)     analysis of the deviation between aggregate forecast
                        Demands supplied by Scheduling Coordinators and that
                        forecast by ISO;

                (b)     analysis of patterns of unplanned Generating Unit
                        Outages;





                (c)     analysis of patterns of shortfalls between Final
                        Day-Ahead Schedules and actual Generation and Demand;

                (d)     analysis of patterns of unexpected transmission Outages;

                (e)     analysis of seasonal variations that may require
                        additional Replacement Reserves; and

                (f)     other factors influencing the ISO Controlled Grid's
                        ability to meet Applicable Reliability Criteria.


ASRP 6.3 SCHEDULING COORDINATOR'S OBLIGATION FOR REPLACEMENT RESERVE

                Scheduling Coordinator's Obligation for Replacement Reserve for
                each Settlement Period of the Day-Ahead Market and for each
                Hour-Ahead Market in each zone shall be based upon the ratio of
                the Demand scheduled by each Scheduling Coordinator in each
                identified Zone for that Settlement Period to the total
                scheduled Demand for that Settlement Period in that Zone.
