        (b)   Each

Agreement shall commence on the date hereof (the "Effective Date") and shall remain in effect until terminated by
either Party upon thirty (30) days prior written notice, or as the Parties mutually agree in writing; provided, however, that this Agreement shall remain in effect with respect to any
Transaction(s) entered into prior to the effective date of the termination until both Parties have fulfilled their obligations with respect to such Transaction(s).

statement and the payments thereof will be promptly made and shall bear interest calculated at the Interest Rate from the date the overpayment or underpayment was made until paid;  provided, however, that no adjustment for any statement or payment will be made unless objection to the

Agreement (except for bankruptcy proceedings which are governed by Section 1.3(b) hereof) and such failure shall remain uncured for a period of
ten (10) days after receipt of written notice thereof by the other Party (each such failure shall constitute an "Event of Default"), then, upon

        (b)   No
failure to exercise and no delay in exercising, on the part of the non- defaulting Party, any right, remedy, power or privilege under this Agreement shall

any other right, remedy, power or privilege. The rights, remedies, powers and privileges provided in this Agreement, including with particularity  Section 4.1, are cumulative and not exclusive of
any rights, remedies, powers, and privileges provided by law.

may (but shall be under no obligation to) remedy any Event of Default for the account of and at the sole cost and expense of the defaulting Party. All reasonable out-of-pocket
costs and expenses so incurred (including, without limitation, reasonable attorneys' fees), together with interest thereon at the Interest Rate from the date on which such sums or expenses are paid by

        (a)   Pursuant
to and subject to the terms and conditions set forth herein, the Parties agree that EMMT will, as MWGen's agent, arrange for the sale by MWGen and delivery to
ExGen of all Energy required to be sold to ExGen under the Power Purchase Agreements (the "ExGen Transactions"). For the purposes of this Energy

        (c)   EMMT
may also enter into financial hedge transactions related to the Energy output of the Facilities from time to time. 

        (d)   All
Transactions described in subsections (a) through (c) above (collectively, "Energy Transactions") shall
be entered into by EMMT and MWGen according to the guidelines established and amended from time to time (the "Risk Management Guidelines") by the EMMT
Risk Management Committee, which is comprised of senior officers and representatives of both EMMT and MWGen. EMMT shall be required to use commercially reasonable care in developing and executing
Energy Transactions so as to comply with the Risk Management Guidelines. EMMT shall advise MWGen on marketing and other business strategies from time to time. 

A-1

 

        (e)   The
terms and conditions of the Agreement shall apply to Energy Transactions entered into pursuant to this Energy Schedule, provided that, in case of any conflict
between the Agreement and this Energy Schedule, this Energy Schedule shall govern. Energy Transactions in which MWGen sells Energy to EMMT other than ExGen Transactions in which EMMT acts as MWGen's
agent shall be for a duration of no more than one year, unless agreed to by the Parties in writing. 

        1.2.  Transaction Procedures and Information. 

        (a)   MWGen
shall promptly deliver all material information related to the condition and output of the Facilities or as otherwise reasonably requested by EMMT from time to
time and promptly deliver to
EMMT security coordinator, reliability region, independent system operator, regional transmission organizations, governmental authorities (collectively, "Reliability

effectuate the Transactions provided for in this Energy Schedule. 

        (b)   The
transaction price ("Transaction Price"), quantity ("Transaction

terms and conditions of any financial transaction entered into under this Agreement, shall be established in a Back-to-Back Transaction between EMMT and an unrelated third
party (except for Disclosed Agent Transactions). Each Energy Transaction hereunder shall be designated by EMMT as a "hedge transaction" in EMMT's Energy Trading System or other applicable software at
or before the execution of its corresponding Back-to-Back Transaction (except for Disclosed Agent Transactions, which shall be designated at the time of such Transaction), and

the Transaction Price, Transaction Quantity, and Delivery Point. Such notice may be provided (i) in a monthly accounting journal entry; or (ii) in such other form as agreed by the
Parties in writing. 

        1.3.  Term. 

        (a)   This
Energy Schedule shall commence on the date hereof (the "Schedule Effective Date") and shall remain in effect until
terminated by either Party upon thirty (30) days prior written notice, or as the Parties mutually agree in writing; provided, however, that this Energy Schedule shall remain in effect with
respect to any Transaction(s) entered into prior to the effective date of the termination until both Parties have fulfilled their obligations with respect to such Transaction(s). 

        (b)   This
Energy Schedule shall terminate automatically upon a default by MWGen under the Leases or any MWGen Financing Document, provided that the Parties shall fulfill all
of their obligations with respect to Transactions entered into prior to such termination.

	In
addition to the Support Services provided under Section 2(a) hereof, Customer and Supplier may from time to time contract for the performance of additional services
("Additional Services). Such Additional Services shall be described in task orders ("Task Orders") issued by Customer's representative to Supplier in a form similar to that shown in Exhibit B
attached. Each Task Order shall be sequentially numbered, and shall describe the specific scope of desired Additional Services to be performed, the schedule requirements for completion of such
Additional Services, the specific documents, reports, drawings, specifications, or other deliverables required by the Task Order, and the fixed price (or other basis of compensation) for the
completion of such Additional Services. 

        Customer's Representative.    Fred McCluskey is hereby designated as Customer's representative for the Support Services. The
individual that executes and issues a Task Order to the Supplier is hereby designated as Customer's representative for the Additional Services to be performed under the subject Task Order. 

3.    Compensation and Payment.    

	(a)
	The
costs of the centralized Support Services provided by Supplier hereunder shall be segregated by functional area of services. Invoices for Support Services shall show such costs
broken down by cost type.

	(b)
	As
consideration for providing the services described under Paragraph 2(b), Customer shall compensate Supplier for the Additional services in the amount and manner specified in
the applicable Task Order. 

 
	(c)
	Supplier
agrees that the compensation set forth in this Agreement (with respect to Support Services) or in the applicable Task Order (with respect to Additional Services) (in each
case including reimbursable expenses, if any) constitutes Supplier's entire compensation in connection with such Services, that no other cost liability rests with Customer, and that all indirect labor
costs of each employee including but not limited to salary premiums; worker's compensation, medical, dental, salary continuance, life, or other insurance; and vacation, sick leave, and holiday pay are
the sole responsibility of Supplier.

	(d)
	Supplier's
direct expenses are defined as the out-of-pocket, non-labor costs incurred as a direct result of providing Support Services or
Additional Services. Direct expenses include such items as transportation, meals, and lodging while out of town; administrative costs for printing, binding, or reproduction of documents; and

Additional Services, shall be reimbursable at actual cost.

	(d)
	Supplier

compensation on a lump sum fixed price basis). Invoices shall be in a form satisfactory to Customer and shall be supported by such documents as Customer may reasonably request. Customer shall have the
right at any time to review the detailed charges that support the monthly invoices. If Supplier is working on multiple Task Orders, the monthly invoices shall show the actual hours allotted to each
Task Order. Supplier shall also submit to Customer an itemization (supported by receipts) of direct project expenses in form and detail reasonably acceptable to Customer, on a periodic (no more than
monthly) basis. Customer shall reimburse all expenses within thirty days of Customer's receipt of Supplier's invoice. All such itemizations shall reference the Task Order number to which such expenses
apply.

	(d)
	Invoices
rendered under this Agreement shall be due and payable within ten (10) days of receipt by Customer. In the case of a dispute over amounts invoiced by Supplier,
Customer shall pay the undisputed portion of the invoice in full and promptly notify Supplier of such dispute and the reasons therefor. Promptly after receipt of such a notice, the Parties shall
consult together with a view to resolving the dispute, failing which either Party may seek resolution of the dispute in accordance with Paragraph 23. Any amounts owing to either Party under
this Agreement which are not paid within thirty (30) days after the due date shall accrue interest at a rate equal to the lesser of (i) one and one-half percent (1.5%) per
month or (ii) the maximum rate allowed by law. 

5.    Insurance.    Supplier and Customer waive all rights against each other and their directors, officers, partners, agents,
subcontractors, and employees for damages covered by insurance during and after the completion of the Services. 

6.    Warranty.    Supplier shall perform the Services with the degree of care, skill and diligence normally provided by other
professionals engaged in similar services. In addition, Supplier's performance of the Services shall be in accordance with applicable law and consistent with Supplier's professional knowledge and
judgment. If any of the Services do not conform to the above standards, Customer's exclusive remedy shall be to require Supplier to re-perform such non-conforming Services at
no additional cost to Customer; provided that Customer notifies Supplier of such error within one year after completion of the Services. If Supplier fails to commence re-performance of the
Services within thirty (30) days of its receipt of Customer's request for re-performance and thereafter diligently to prosecute such re-performance to completion,
Customer shall have the right to hire a third party to perform such non-conforming Services and Supplier shall be required to reimburse Customer for all reasonable costs incurred by
Customer in connection with the performance of such Services which are in excess of amounts owed to Supplier, subject to the limits of Supplier's liability set forth below.

years after the term of this Agreement. During the term of this Agreement and for two years thereafter, Supplier shall make its books and records available to Customer and its duly authorized
representatives for inspection and audit at Supplier's regular place of business and during normal business hours to the extent necessary to verify the amounts claimed and to verify compliance with
laws.

notice to Supplier. In the event this Agreement is terminated, Customer shall pay for the portion of the Services performed through the date of termination (determined, if necessary, on a pro rata
basis), as well as any other amounts due and payable to Supplier as of the date of termination and, upon such payment, Customer shall have no further obligation to Supplier. Following any notice of
termination, Supplier shall fully cooperate with Customer in all matters relating to the winding up of its pending Services on behalf of Customer and the orderly transfer of any such pending Services
to such other persons as may be designated by Customer. Upon termination of this Agreement, Supplier shall deliver to Customer all Work Product and other information received from Customer. Customer's
rights and remedies under this Paragraph 8 shall in no way limit Customer's rights as set forth in Paragraph 6 above or as otherwise provided by law. 

9.    Force Majeure.    If either Party is prevented or delayed in performing its duties hereunder (other than Customer's duty to
compensate Supplier hereunder) due to an event of Force Majeure, the time provided for performance by such Party shall be extended for a period equal to the period by which its performance was
prevented or delayed by Force Majeure. "Force Majeure" shall mean an event outside a Party's reasonable control, which event such Party is unable to prevent or provide against by the exercise of
reasonable diligence, and shall include, but not be limited to, acts of God or the public enemy, war, insurrection, riot, civil commotion, fire, flood, explosion, hurricane, tornado, epidemic,

accepts, the entire right, title and interest of Supplier in and to the Work Product and to all copyrights, trade secrets, and other proprietary rights therein or based thereon. Supplier reserves to
itself the right to use the Work Product in connection with the rendering of services to other customers. "Work Product" shall mean all data, documentation, software and information, in whatever form,
first produced or created by or for Supplier, or provided to or by Supplier as a result of or related to the performance of the Work. Supplier and Customer agree that if the Work Product or any
portion thereof is copyrightable, it shall be deemed to be a "work made for hire," as such term is defined in the Copyright Laws of the United States. 

        Supplier
hereby grants to Customer, and Customer hereby accepts, a non-transferable, perpetual, irrevocable, royalty-free, fully paid-up, worldwide
and nonexclusive right and license to use the Background Work in connection with its use of the Work Product. "Background Work" shall mean all data, documentation, software and information, in
whatever form, not first produced or created by or for Supplier as a result of or related to the performance of the Services, but included in or with or

as an agent, partner, joint venturer or employee of Customer or its affiliates. Supplier shall not represent to third persons that Supplier's status with respect to Customer is anything other than
that of an independent contractor. Supplier shall not have any express or implied right or authority to assume or create any obligations on behalf or in the name of Customer or to bind Customer to any
contract or undertaking with any other person, nor shall Supplier represent that it has such authority. Supplier and its employees and agents shall not be entitled to any Customer fringe benefits and
hereby expressly waive any claim or right any may have against Customer arising out of the operation of any applicable workers' compensation law. 

12.    Confidentiality.    In connection with the Services, Customer may disclose and make available to Consultant certain of its
files, documents and information regarding its projects and its policies and procedures, as well as other related information. This information (hereinafter called the "Confidential Information") is
secret and proprietary to Customer, and Customer desires to keep such Confidential Information confidential. Supplier shall not, without the prior written consent of Customer, publish or make
accessible to any firm, corporation or any other person, any Confidential Information or use such Confidential Information (other than in connection with the Services); provided, however, no
confidentiality obligation shall apply to any information (a) that is generally available to the public, (b) was already known to Supplier on a non-confidential basis on the
day of receipt of such information, or (c) is subsequently disclosed to Supplier on an non-confidential basis by a third party not having a confidential relationship with Customer
or its affiliates with respect to such information. 

        Notwithstanding
the foregoing, Supplier shall be free to disclose any Confidential Information to the extent and only to the extent (i) necessary in accordance with any applicable
law and (ii) during the course of or in connection with any governmental investigation, arbitration or other proceedings or (iii) required or requested by any federal, state or local
regulatory body or agency having jurisdiction. Prior to any disclosure pursuant to the preceding sentence, Supplier shall be required to give reasonable prior notice to Customer of such intended
disclosure and, if requested by Customer and at Customer's expense, to use all reasonable efforts to obtain a protective order or similar protection for Customer. 

13.    Representations.    Each Party hereto represents that it is a corporation or partnership duly organized, validly existing and
in good standing under the laws of its jurisdiction of incorporation or formation and that performance of this Agreement will not violate any law, permit, agreement or by-law to which it
is subject.
