                  Section 4. An example of the calculation and application of
                  the Price Adjustment described in this Section 4 is set forth
                  in Appendix A hereto.

            4.2   A Price Adjustment shall be calculated for each Contract

                  Monthly Price
                  Adjustment =      [Market Price - (Floor Price x Monthly
                                    Base Price Factor)] x nine percent (9%) x
                                    (the sum of the Net Electric Output during
                                    each hour of the Contract Month up to a
                                    maximum total amount of Energy in each such
                                    hour of 1,148 MWh).

                  WHERE:

                  Market Price =    Market Energy Price + Market Capacity Price
                                    for the respective Contract Month.

                  Market
                  Energy Price =    The average over all hours of the respective
                                    Contract Month of the day-ahead locational
                                    based market price ("LBMP") paid to
                                    producers for energy at the NMP-2 Delivery
                                    Point (defined in the NMP-2 Interconnection

                                    Agreement) specified and published by the
                                    NYISO or, if the NYISO does not specify or
                                    publish an LBMP for the NMP-2 Delivery
                                    Point, the LBMP specified and published by
                                    the NYISO for the region in which the NMP-2
                                    Delivery Point is located. In the event the
                                    NYISO ceases to provide such prices, the
                                    Parties shall in good faith undertake
                                    commercially reasonable efforts to agree on
                                    a substitute indices to reflect the value of
                                    Energy located at the NMP-2 Delivery Point.
                                    Failure of the parties to agree to such
                                    alternative indices shall constitute a
                                    dispute to be resolved in accordance with
                                    the provisions of Section 5.4.

                  Market
                  Capacity Price =  The market value of the installed capacity
                                    of NMP-2, expressed in $/MWh. The measure
                                    will reflect the weighted average of the
                                    market prices paid to producers for
                                    installed capacity at the NMP-2 Delivery
                                    Point as published by the NYISO in its
                                    installed capacity auctions. Where Market
                                    Capacity Prices are posted in units of
                                    $/kW-month, such conversion to units of
                                    $/MWh shall be the result of the posted
                                    price in $/kW-month, multiplied by 41.66666,
                                    divided by the number of days in the month.
                                    (For example, if the posted price was $1.50
                                    /kW-month for a month which is 30 days long,
                                    the $/MWh would be $2.0833/MWh [($1.50 x
                                    41.6666)/30]. Note 41.6666 = 1000kW/MWh /24
                                    hours per day). In the event NYISO ceases to
                                    provide such prices, the Parties shall in
                                    good faith undertake commercially reasonable
                                    efforts to agree on a substitute indices to
                                    reflect the value of installed capacity
                                    located at the NMP-2 Delivery Point. Failure
                                    of the parties to agree to such alternative
                                    indices shall constitute a dispute to be
                                    resolved in accordance with the provisions
                                    of Section 5.4.

                  Floor Price =     Set forth in Schedule 1.

                  Monthly Base
                  Price Factor =    Set forth in Schedule 2.

            4.4   If the Price Adjustment for a Contract Quarter is negative,
                  PRODUCER shall accrue eighty percent (80%) of that negative
                  Price Adjustment (that 80% defined herein as the "Negative
                  Price Adjustment Amount") to be credited against Positive
                  Price Adjustment Amounts, if any, for subsequent Contract
                  Quarters, thereby reducing such Positive Price Adjustment
                  Amounts until the full amount of such Negative Price
                  Adjustment Amounts has been so credited.

            4.5   If the Price Adjustment for a Contract Quarter is positive,
                  PRODUCER shall:

                  (i)   take 80% of that positive Price Adjustment (the 80%
                        defined herein as the "Positive Price Adjustment
                        Amount"); then

                  (ii)  credit against and reduce the Positive Price Adjustment
                        Amount by the sum of any Negative Price Adjustment
                        Amounts for prior Contract Quarters, to the extent that
                        any such Negative Price Adjustment Amounts have not been
                        credited against Positive Price Adjustment Amounts; then

                  (iii) make payment of the Purchase Price Adjustment in an
                        amount equal to any Positive Price Adjustment Amount
                        remaining after crediting any Negative Price Adjustment
                        Amounts as described in (ii) above.

            4.6   Negative Price Adjustment Amounts calculated with respect to a
                  Contract Quarter shall only be credited against Positive Price
                  Adjustment Amounts, if any, for subsequent Contract Quarters.
                  CUSTOMER shall have no obligation to make any payment to
                  PRODUCER in respect of any Negative Price Adjustment Amount,
                  whether by way of refund of payments made by PRODUCER in
                  respect of Positive Price Adjustment Amounts for prior
                  Contract Quarters, payment for Negative Price Adjustment
                  Amounts which are not followed by Positive Price Adjustment
                  Amounts against which such Negative Price Adjustment Amounts
                  may be credited, or otherwise.

            4.7   EXTRAORDINARY INFLATION: On each anniversary of the date
                  hereof, if the United States Gross Domestic Product Implicit
                  Price Deflator (as reported quarterly by the United States
                  Department of Commerce; the "GDP Deflator") for the most
                  recently reported quarterly period has increased by more than
                  5% from the same quarterly period in the prior year, the Floor
                  Price for each subsequent Contract Year set forth in Schedule
                  1 hereof, shall be

                                       5
<PAGE>

                  increased by the percentage amount such increase is greater
                  than 5%. For example, if on the first anniversary date hereof
                  the GDP Deflator for the most recent quarter equals 112, and
                  the GDP Deflator for the same quarter reported in the previous
                  year was 105, each Contract Year in Schedule 1 hereof shall be
                  increased by 1.66%.

      5. PAYMENT AND DISPUTES.

            5.1   STATEMENTS AND PAYMENTS. PRODUCER shall prepare a statement
                  ("Statement") for each Contract Quarter showing the Price
                  Adjustment Payment due to CUSTOMER, if any, for such Contract
                  Quarter and the calculation of the Price Adjustment Amount for
                  such Contract Quarter (whether positive or negative). PRODUCER
                  will provide to CUSTOMER such Statement on or before the tenth
                  (10th) Business Day after the final Contract Month of each
                  Contract Quarter. PRODUCER shall pay the amount due, if any,
                  by wire transfer of immediately available funds to an account
                  specified by CUSTOMER not later than the fifth (5th) Business
                  Day after the date on which PRODUCER provides the Statement.

            5.2   OVERDUE PAYMENTS. Overdue payments shall accrue interest at
                  the Interest Rate from, and including the due date to, but
                  excluding, the date of payment.

            5.3   BILLING DISPUTES. If CUSTOMER, in good faith, disputes any
                  Statement or part thereof, CUSTOMER shall notify PRODUCER in
                  writing of the basis for the dispute within ten (10) business
                  days of receipt of the Statement. If it is subsequently
                  determined by arbitration or agreed that an adjustment to the

                  revised Statement not later than ten (10) Business Days after
                  it is determined that an adjustment is appropriate. Any Price
                  Adjustment Payment due to CUSTOMER pursuant to the revised
                  Statement shall be paid by wire transfer of immediately
                  available funds to the account specified by CUSTOMER not later
                  than three (3) Business Days from the date the revised
                  Statement is issued and shall include interest accrued at the
                  Interest Rate until the date paid.

                        otherwise. Any award of amounts due shall include
                        interest accrued at the Interest Rate until the date
                        paid. Judgment may be entered upon the arbitration

                        the resolution of disputes. Each Party is required to
                        continue to perform its obligations under this Agreement
                        pending final resolution of a dispute. All negotiations
                        pursuant to these procedures for the resolution of
                        disputes will be confidential, and shall be treated as
                        compromise and settlement negotiations for purposes of
                        the Federal Rules of Evidence and State Rules of
                        Evidence and similarly applicable rules or regulations
                        of any state or federal regulatory agency with
                        jurisdiction over a Party.
