         4.1 DETERMINATION OF AGENCY PERIOD. If, at any time, MAEM determines
that the creditworthiness of the Project Companies is impaired, MAEM may, at its
sole discretion and upon written notice to the Project Companies, elect to
suspend fuel procurement under the Fuel Supply Agreement for a period until such

as agent of and for the account of the Project Companies, and MAEM shall have no
obligation to provide credit enhancement to any supplier of the Project
Companies. MAEM shall have no liability to either of the Project Companies if
fuel suppliers do not agree to supply fuel to the Project Companies due to a
lack of creditworthiness of the Project Companies. As agent, MAEM shall neither
directly purchase or contract for the purchase of, nor take title to or
possession and control of, any fuel procured for the account of the Project
Companies, and MAEM shall have no liability to any fuel supplier or the Project
Companies for nonpayment for or nondelivery of procured fuels, as appropriate.
During any Agency Period, as between MAEM and the Project Companies, the Project
Companies shall be deemed to have title, exclusive possession and control of all
procured fuel at all times, and any risk of loss associated with any such
procured fuel shall be born by the Project Companies.

         4.3 TERMINATION OF AGENCY PERIOD. Each Agency Period shall continue
until the Project Companies can demonstrate to MAEM that the Project Companies'
creditworthiness has been restored, as reasonably determined by MAEM. After a
positive determination as to such creditworthiness, the applicable Agency Period
shall be terminated by MAEM by written notice to Project Companies, and MAEM
shall resume procuring fuel for the Project Companies under the Fuel Supply
Agreement.


                                   ARTICLE 5.
                           BONUS, BILLING AND PAYMENT

         5.1 NEW YORK ASSET BOOK. MAEM will establish and maintain an asset
management book (the "New York Asset Book") to track and measure the financial
performance of the Project Companies assets. The New York Asset Book will be
separate from any MAEM trading book or any other asset book maintained by MAEM
for power resources owned or managed by MAEM.

         5.2 BONUS.

         (a) MAEM will be entitled to a bonus from the Project Companies equal
to the Bonus Percentage of the amount by which the Net Market Revenues in any
year exceeds the Threshold Amount for such year, determined as follows:

         "Net Market Revenues" means all revenues for a given year attributed to
         the New York Asset Book and actually received by MAEM, including,
         without limitation, payments for sales of capacity, energy and
         ancillary services (including payments under the Load Pocket
         Agreements), fuel and fuel transportation rights, and hedges and other
         risk management instruments entered into by MAEM on behalf of the
         Project Companies MINUS all costs attributed to the asset books for
         such year, including costs reimbursed to MAEM for fuel and services.
         Net Market Revenues shall be calculated in accordance with GAAP.

         "Threshold Amount" means $197,211,000.00 for 2001.

         "Bonus Percentage" means 50% for 2001.

         (b) If this Agreement is extended pursuant to ARTICLE 2 hereof, the
Threshold Amount and Bonus Percentage for subsequent years shall be determined
by mutual agreement between MAEM and the Project Companies as a reasonable
amount based on upon assumptions consistent in all material respects with
relevant contracts and agreements, historical operations, and the parties' good
faith projections of future revenues and projections of operating expenses for
the Project Companies in light of the then existing or reasonably expected
regulatory and market environments in the markets in which the facilities or
other assets owned by the Project Companies will be operated.


                                       6

<PAGE>

         (c) The bonus shall not be payable until the Threshold Amount is
reached. Upon reaching the Threshold Amount, such bonus will be paid on a
monthly basis in accordance with SECTION 5.3 hereof.

         5.3 BILLING AND PAYMENT. MAEM shall pay the Project Companies any Net
Market Revenues due for the prior month by wire transfer to the payment address
provided by the Project Companies on or before the twentieth (20th) day of each
month, or if such day is not a business day, the immediately following business
day. At the time of each monthly payment, MAEM shall render to the Project
Companies a statement detailing the Net Market Revenues for the prior month, and
shall provide the Project Companies with reasonable supporting documentation for
each such monthly statement, identifying with reasonable specificity
calculations underlying such Net Market Revenues. All payments between MAEM and
the Project Companies will be netted so that MAEM pays the Project Companies the
Net Market Revenues minus any bonus payable pursuant to SECTION 5.2.

         5.4 REPORTS. The Project Companies and MAEM will cooperate to provide
monthly reports in reasonable detail showing the calculation of the Net Market
Revenues, with appropriate breakdown by generating unit and station, to enable
the Project Companies to allocate Net Market Revenues and bonus payments to
MAEM, if any, between the Project Companies. Each of the Project Companies will
have the right, upon reasonable notice, to examine and/or audit the New York
Asset Book from time to time.

         5.5 INTEREST AND DISPUTED AMOUNTS. If any Party fails to make any
payment on or before the applicable payment due date, such overdue amounts shall
accrue interest at the Interest Rate from, and including, the applicable payment
due date to, but excluding, the date of payment. Any disputed invoiced amounts,
except amounts which are manifestly inaccurate, shall be paid in full on the
applicable payment due date, subject to later return together with interest
accrued at the Interest Rate. Overpayments or underpayments identified by the
Parties shall be returned or credited, together with interest accrued at the
Interest Rate, to their rightful owners in the first following month.

                                   ARTICLE 6.
                              DEFAULTS AND REMEDIES

         6.1 EVENTS OF DEFAULT. Any one or more of the following shall

<PAGE>

         (c) a Bankruptcy Proceeding has occurred with respect to such Party; or

         (d) a representation or warranty made by such Party herein shall have
been false or misleading in any material respect when made; provided, however,
if such representation or warranty is capable of being corrected, no Event of
Default shall have occurred if such Party is diligently pursuing such correction
and such representation or warranty is corrected within thirty (30) days of such
Party obtaining knowledge of the false and misleading nature of the statement.

         6.2 REMEDIES. The Parties shall have the following remedies available
to them hereunder:

         (a) Upon the occurrence of an Event of Default by either Party
hereunder, the non-defaulting Party shall have the right (i) to collect all
amounts then or thereafter due to it from the defaulting Party hereunder, and
(ii) upon written notice to the other Party, to terminate this Agreement at any
time during the continuation of such Event of Default. The terminating Party
shall have all rights and remedies available to it under applicable law, subject
to the limitations set forth in SECTION 8.7.

         (b) Without limiting the foregoing, any unexcused breach of this
Agreement or failure of either Party to perform its obligations hereunder shall
subject such Party to the payment of actual damages to the other Party,
regardless of any cure period.

                                   ARTICLE 7.
                                  FORCE MAJEURE

         If either Party is rendered wholly or partly unable to perform its
obligations under this Agreement because of a Force Majeure event, that Party
will be excused from whatever performance is affected by the Force Majeure event
to the extent so affected, provided that (a) the non-performing Party, as soon
as practical after knowing of the occurrence of the Force Majeure event, gives
the other Party written notice describing the particulars of the occurrence; (b)
the suspension of performance is of no greater scope and of no longer duration
than is reasonably required by the Force Majeure event; (c) the non-performing
Party uses commercially reasonable efforts to overcome or mitigate the effects
of such occurrence; and (d) when the non-performing Party is able to resume
performance of its obligations hereunder, that Party shall give the other Party
written notice to that effect and shall promptly resume such performance.

                                   ARTICLE 8.
                            MISCELLANEOUS PROVISIONS

         8.1 ASSIGNMENT; SUCCESSORS AND ASSIGNS. No assignment or delegation by
either Party (or any successor or assignee thereof) of this Agreement, in whole
or in part, shall be made or become effective without the prior written consent
of the other Party in each case obtained, which consent may not be unreasonably
withheld. Any assignments or delegations by either Party shall be in such form
as to assure that such Party's obligations under this Agreement will be honored
fully and timely by any succeeding party.
