(m)      Any liabilities relating to the New York State Energy Research and Development Authority Pollution

(n)      Subject to Section 6.18, any liabilities or obligations of Seller relating to or arising from the

                  (o)      All liabilities for fees payable to the Department of Energy under the Department
of Energy Standard Contracts accrued on or prior to the Closing Date, including, without limitation, subject
to Section 6.13, all liabilities for fees, late fees, penalties and other amounts payable to the Department

2.5.     CONTROL OF LITIGATION.  The Parties agree and acknowledge that Seller shall be entitled exclusively
to control, defend and settle any litigation, administrative or regulatory proceeding, and any investigation

                                                    ARTICLE III
                                                    THE CLOSING

3.1.     CLOSING. Upon the terms and subject to the satisfaction of the conditions contained in Article VII
of this Agreement and subject to Section 10.12, the sale, assignment, conveyance, transfer and delivery of
the Purchased Interests to Buyer, the payment of the Purchase Price to Seller, and the consummation of the
other respective obligations of the Parties contemplated by this Agreement shall take place at a closing
(the "Closing"), to be held, simultaneously with the closing of the transactions contemplated by the NMP-2
Asset Purchase Agreement at the offices of Sullivan & Cromwell in New York City, at 10:00 am. local
time, or another mutually acceptable time and location, on the date that is twenty (20) Business Days
following the date on which the last of the conditions precedent to Closing set forth in Article VII of this
Agreement have been either satisfied or waived by the Party for whose benefit such conditions precedent
exist, but in any event not after the Termination Date, unless the Parties mutually agree on another date.
For the sole purpose of planning the Closing Date, the matters contemplated by Section 7.1(g), (h), (i),
(j), (l), (m), (n) and (o) and Section 7.2(h), (i), (j), (k), (l) and (m) shall be assumed to have been
satisfied, provided, however, that  the actual satisfaction of such provisions shall in all cases be
considered to be a condition to Closing.  The date of Closing is hereinafter called the "Closing Date."
The Closing shall be effective for all purposes as of 12:01 a.m. on the Closing Date.

3.2.     PAYMENT OF PURCHASE PRICE.  Upon the terms and subject to the satisfaction of the conditions
contained in this Agreement, in consideration of the aforesaid sale, assignment, conveyance, transfer and
delivery of the Purchased Interests, Buyer will pay or cause to be paid to Seller at the Closing in
consideration of the Purchased Interests an amount equal to the Purchase Price, plus or minus any
adjustments to such Purchase Price pursuant to the provisions of this Agreement, one-half of which shall be
paid by wire transfer of immediately available funds denominated in U.S. dollars or by such other means as
are agreed upon by Seller and Buyer and one-half shall be paid by a Note, in substantially the form of
Exhibit I.

3.3.     ADJUSTMENT TO PURCHASE PRICE.  (a) Subject to Section 3.3(b), at the Closing, the Purchase Price
shall be adjusted, without duplication, to account for the items set forth in this Section 3.3(a):

         (i)      The Purchase Price shall be adjusted to account for the items prorated as of the
         Closing Date pursuant to Section 3.5.

         (ii)     Each full-time regular Transferred Employee, up to 1,337 in number, will be allocated
         to NMP-1 and NMP-2.  As part of this allocation, employees will be allocated 45% to NMP-1 and 55%
         to NMP-2.  For each full-time Transferred Employee allocated to NMP-1 below 550 and above 475, the
         Purchase Price will be increased by $25,000.

         (iii)    The Purchase Price shall be increased by the amount expended by Seller between the
         date hereof and the Closing Date for capital additions to or replacements of property, plant and
         equipment included in the NMP-1 Assets and other expenditures or repairs on property, plant and
         equipment included in the NMP-1 Assets that are capitalized by Seller in accordance with their
         normal accounting policies, provided, that (A) such expenditures are not required (1) for the
         customary operation and maintenance of NMP-1, (2) to replace equipment which has failed for any
         other reason, or (3) to comply with applicable laws, rules and regulations and (B) Buyer has
         specifically requested or approved such expenditures in writing ("Capital Expenditures").
         Nothing in this paragraph should be construed to limit Seller's rights and obligations to make
         all capital expenditures necessary to comply with NRC licenses and other Permits.

         (iv)     The Purchase Price shall be decreased or increased, as the case may be, by 15.49 cents
         for every dollar that Seller's Nonqualified Decommissioning Fund assets transferred to Buyer exceed,
         or are less than the Nonqualified Target.  In addition, if the Closing Date occurs after July 1,
         2001, the Purchase Price shall be increased by one dollar for every dollar that the Seller's
         Nonqualified Decommissioning Fund exceeds the Nonqualified Target, but only to the extent such
         excess results from a contribution required by federal Income Tax law or the terms of the trust
         agreement applicable to such fund to be made to the Seller's Nonqualified Decommissioning Fund
         after the date hereof.

         (v)      The Purchase Price shall be adjusted from time to time following the Closing Date by
         the payment under the Revenue Sharing Agreement, if any, to Seller as required under the Revenue
         Sharing Agreement.

         (vi)     The Purchase Price shall be adjusted, if applicable, as provided in Section 7.1(p).

         (vii)    If the cost to dispose of the Low Level Waste at the Facilities as of the Closing Date
         is greater than $250,000, based on the disposal criteria set forth in Schedule 3.3(a)(vii), the
         Purchase Price shall be adjusted downward by one dollar for every dollar that such Low Level Waste
         disposal is greater than $250,000.  Conversely, if the cost to dispose of the Low Level Waste at
         the Facilities as of the Closing Date is less than $250,000, the Purchase Price shall be adjusted
         upward by one dollar for every dollar that such Low Level Waste disposal is less than $250,000.

         (viii)   The Purchase Price shall be increased by the amount of two million dollars ($2,000,000) per
         year for each year (the "Contingent Payment") after 2034 (which amount shall increase by 3.5% for
         each year following the first year) that Buyer has failed to receive terminations of all Part 50
         licenses from the NRC with respect to NMP-1.  Payment of the additional Purchase Price, if any,
         shall be made by Buyer to Seller within thirty (30) days following the close of each calendar year
         in which a Contingent Payment under this Section 3.3(a)(viii) is required.  This Section 3.3(a)
         (viii) will be operative only upon the receipt of a private letter ruling issued by the Internal
         Revenue Service (the "IRS") to Seller, which provides, in a form acceptable to Seller, that the
         amounts payable, if any, under this Section 3.3(a)(viii) will both:  (I) not be included in
         determining the taxable income for the taxable year of Seller until the Contingent Payment is fixed
         by the failure of Buyer to Decommission NMP-1 after 2034; and (II) not adversely affect Seller's
         Federal income tax consequences as contemplated in Section 6.12(b)(i) and Section 6.12 (b)(ii).
         Notwithstanding the preceding sentence, if the IRS refuses, or otherwise fails, to issue the ruling
         contemplated under Section 3.3(a)(viii)(I) above, this Section 3.3(a)(viii) nevertheless will be
         operative provided that Seller receives an opinion (or opinions as determined by Seller) of counsel,
         acceptable to Seller, with respect to Section 3.3(a)(viii)(I), and the IRS issues the rulings that
         Seller is entitled to the Federal income tax consequences as contemplated in Section 6.12(b)(i) and
         Section 6.12(b)(ii).  Neither the receipt of the rulings nor any opinion of counsel contemplated by
         this Section 3.3(a)(viii) is required as a condition to be fulfilled under this Agreement at or prior
         to the Closing Date.

         (ix)     The Purchase Price shall be decreased by one dollar for every dollar that Seller's
         Qualified Decommissioning Fund assets transferred to Buyer are less than the Qualified Target.
         In addition, if the Closing Date occurs after July 1, 2001, the Purchase Price shall be increased by
         one dollar for every dollar that the Seller's Qualified Decommissioning Fund exceeds the Qualified
         Target, but only to the extent such excess results from a contribution required by federal Income
         Tax law or the terms of the trust agreement applicable to such fund to be made to the Seller's
         Qualified Decommissioning Fund by Seller after the date hereof.

                  (b)      No less than ten (10) Business Days prior to the Closing Date, Seller shall
         prepare and deliver to Buyer an estimated closing statement (the "Estimated Closing Statement")
         that shall set forth Seller's best estimate of all estimated adjustments to the Purchase Price
         required by Section 3.3(a) (other than subsections 3.3(a)(v) and 3.3(a)(viii)) (the "Estimated
         Adjustment").  Within ten(10) calendar days after the delivery of the Estimated Closing Statement
         by Seller to Buyer, Buyer may object in good faith to the Estimated Adjustment in writing.  If
         Buyer objects to the Estimated Adjustment, the Parties shall attempt to resolve their differences
         by negotiation.  If the Parties are unable to do so prior to the Closing Date (or if Buyer does not
         object to the Estimated Adjustment), the Purchase Price shall be adjusted (the "Closing Adjustment")
         for the Closing by the amount of the Estimated Adjustment not in dispute.  The disputed portion
         shall be resolved in accordance with the provisions of Section 3.3(c) and paid as part of any
         Post-Closing Adjustment to the extent required by Section 3.3(c).

                  (c)      Within sixty (60) days after the Closing Date, Seller shall prepare and deliver to
         Buyer a final closing statement (the "Post-Closing Statement") that shall set forth all adjustments
         to the Purchase Price required by Section 3.3(a) (other than subsections 3.3(a)(v) and 3.3(a)(viii))
         (the "Proposed Post-Closing Adjustment") and all work papers detailing such adjustments.  The
         Post-Closing Statement shall be prepared using the same accounting principles, policies and methods
         as Seller has historically used in connection with the calculation of the items reflected on such
         Post-Closing Statement.  Within thirty (30) days after the delivery of the Post-Closing Statement
         by Seller to Buyer, Buyer may object to the Proposed Post-Closing Adjustment in writing.  Seller
         agrees to cooperate with Buyer to provide Buyer with the information used to prepare the
         Post-Closing Statement and information relating thereto.  If Buyer objects to the Proposed
         Post-Closing Adjustment, the Parties shall attempt to resolve such dispute by negotiation.  If
         the Parties are unable to resolve such dispute within thirty (30) days after any objection by
         Buyer, the Parties shall appoint the Independent Accounting Firm, which shall, at Seller's and
         Buyer's joint expense, review the Proposed Post-Closing Adjustment and determine the appropriate
         adjustment to the Purchase Price, if any, within thirty (30) days after such appointment.  The
         Parties agree to cooperate with the Independent Accounting Firm and provide it with such information
         as it reasonably requests to enable it to make such determination.  The finding of such
         Independent Accounting Firm shall be binding on the Parties hereto.  Upon determination of the
         appropriate adjustment (the "Post-Closing Adjustment") by agreement of the Parties or by binding
         determination of the Independent Accounting Firm, the Party owing the difference shall deliver such
         amount to the other Party no later than two (2) Business Days after such determination, in
         immediately available funds or in any other manner as reasonably requested by the payee.

3.4.     ALLOCATION OF PURCHASE PRICE.  At least ten (10) Business Days prior to the Closing Date, Buyer and
Seller shall agree upon an allocation among the NMP-1 Assets of the sum of the Purchase Price and the Assumed
Liabilities and Obligations, which will be memorialized on Schedule 3.4; provided, however, the parties shall
allocate a portion of the Purchase Price equal to the Fuel Market Value to the purchase of each KgU of fuel
held in inventory or loaded into the Unit.  The agreed allocation shall be used by the parties for all
purposes except as otherwise required by Section 1060 of the Code.

3.5.     PRORATIONS.  (a) Buyer and Seller agree that all of the items normally prorated, including those
listed below (but not including Income Taxes), relating to the business and operation of the NMP-1 Assets
shall be prorated as of the Closing Date, with Seller liable to the extent such items relate to any time
period prior to the Closing Date, and Buyer liable to the extent such items relate to periods commencing
with the Closing Date (measured in the same units used to compute the item in question, otherwise measured
by calendar days):

                  (i)      Personal property, real estate and occupancy Taxes, assessments and other
         charges, if any, on or with respect to the business and operation of the NMP-1 Assets;

                  (ii)     Rent, Taxes and all other items (including prepaid services or goods not included
         in Inventory) payable by or to Seller under any of Seller's Agreements or the Non-material
         Contracts;

                  (iii)    Any permit, license, registration, compliance assurance fees or other fees with
         respect to any Transferable Permit;

                  (iv)     Sewer rents and charges for water, telephone, electricity and other utilities; and

                  (v)      Rent and Taxes and other items payable by Seller under the Real Property
         Agreements assigned to Buyer.

                  (b)      In connection with the prorations referred to in (a) above, in the event that
actual figures are not available at the Closing Date, the proration shall be based upon the actual Taxes or
other amounts accrued through the Closing Date or paid for the most recent year (or other appropriate period)
for which actual Taxes or other amounts paid are available.  Such prorated Taxes or other amounts shall be
re-prorated and paid to the appropriate Party within sixty (60) days of the date that the previously
unavailable actual figures become available.  The prorations shall be based on the number of days in a year
or other appropriate period (i) before the Closing Date and (ii) including and after the Closing Date.
Seller and Buyer agree to furnish each other with such documents and other records as may be reasonably
requested in order to confirm all adjustment and proration calculations made pursuant to this Section 3.5.

3.6.     DELIVERIES BY SELLER.At the Closing (or, in the case of those items contemplated by paragraph (j)

3.8.     PRE-CLOSING BREACHES OF SELLER'S REPRESENTATIONS AND WARRANTIES.

         (a)      To the extent that, prior to Closing, it is determined that, if the qualification
of materiality or Material Adverse Effect were deleted from the Seller's representations and warranties
which do not survive the Closing under Section 10.3(a), there would be any individual breach of any of the
Seller's representations or warranties which do not survive the Closing under Section 10.3(a) which would be
reasonably likely to result in any claims, demands, suits, losses, liabilities, damages, obligations,
payments, costs and expenses (including, without limitation, the costs and expenses of any and all actions,
suits, proceedings, assessments, judgments, settlements and compromises relating thereto and reasonable
attorneys' fees and reasonable disbursements in connection therewith) to the Buyer ("Damages") of $3,000,000
or more (a "Pre-Closing Breach"), then, to the extent that the aggregate amount of the Damages of all
Pre-Closing Breaches exceeds $10,000,000, Seller shall hold the Buyer harmless from such Damages in excess
of $10,000,000 by taking, at its option, either or both of the following actions: (i) cure the breach before
the Closing, provided that the Closing shall not be delayed to effect any cure; or (ii) adjust the Purchase
Price prior to the Closing by an amount agreed to by the Parties.

         (b)      To the extent the exact amount of the Damages of the Pre-Closing Breach cannot
reasonably be agreed upon by the Parties prior to the Closing, and neither option (i) nor (ii) above is
implemented, within 10 days after such Pre-Closing Breach is brought by another Party to the attention of the
other Parties, such dispute (the "Dispute") may be submitted by any Party to, and if so submitted shall be
finally settled by, arbitration ("Arbitration") in accordance with the Commercial Arbitration Rules of the
American Arbitration Association (the "Rules"), but any such Arbitration would have the following
characteristics: (i) there would be one arbitrator (the "Arbitrator"), selected by the Parties acting in good
faith, which Arbitrator must be a person with substantial experience and knowledge relating to nuclear power
plants; (ii) if the Parties cannot agree on the identity of the Arbitrator by the end of the above-described
10 day period, such person shall be appointed in accordance with the Rules; (iii) the Arbitrator must enter a
decision that the amount of Damages is either the amount proposed by the Buyer or the amount proposed by the
Seller and no other amount, and, if such decision is entered prior to the Closing, the Purchase Price
otherwise payable at the Closing under this Agreement shall be reduced by the amount of Damages (the "Damage
Amount") so decided; (iv) the Arbitrator must make his decision no earlier than 15 and no later than 30 days
after the date on which he is appointed as Arbitrator; (v) if the Parties can agree amongst themselves on the
amount of the Damages which are the subject of the Dispute before the 15th day after which the Arbitrator is
appointed, such agreement shall control and the Arbitration shall be terminated without result; (vi) all
costs of such Arbitration, including the compensation of the Arbitrator (but not including the Parties'
attorneys', accountants' and other professionals' fees, as to which each Party shall pay its own), shall be
split evenly between the Buyer and Seller; (vii) the Arbitration would take place in Onondaga County, New
York; and (viii) the decision of the Arbitrator shall be final and binding upon the Parties.  In no event
shall any actions taken pursuant to this subsection (b) delay the Closing.

         (c)      No Dispute or Arbitration shall delay the Closing, and if any Dispute or
Arbitration is ongoing at the time the Closing is otherwise able to occur under this Agreement, the Closing
shall proceed and the process described in Section 3.8(b) shall continue past the Closing Date.  In such
case, the Damage Amount as determined by the Arbitrator after the Closing shall be recoverable by the Buyer
against the Seller, and the Seller shall pay the Damage Amount to the Buyer within seven days after the date
of the Arbitrator's decision.  If the Seller does not fully make such payment by the end of such seven day
period, the Buyer may proceed in one  of the following ways, or a combination thereof, at the Buyer's sole
election:  (i) setting off the Damage Amount against any amount(s) otherwise owing from the Buyer to the
Seller under this Agreement, and (ii) causing the entering of a judgment against the Seller in a court of
competent jurisdiction consistent with Section 10.6 hereof with respect to, and to enforce the decision of,
the Arbitrator hereunder.

         (d)      The Parties specifically agree that the threshold of $3,000,000 does not
constitute materiality or a Material Adverse Effect under this Agreement.

                                                    ARTICLE IV
                                     REPRESENTATIONS AND WARRANTIES OF SELLER

         Seller hereby represents and warrants to Buyer as follows (all such representations and warranties,
other than those in Sections 4.1, 4.2, 4.3, 4.12, 4.19, 4.20, 4.21 and 4.22, being made to the Knowledge of
Seller):

4.1.     ORGANIZATION. Seller is a corporation duly organized, validly existing and in good standing under

bound, except for such defaults (or rights of termination, cancellation or acceleration) as to which
requisite waivers or consents have been obtained or which would not, individually or in the aggregate,
create a Material Adverse Effect; or (iii) constitute violations of any order, writ, injunction, decree,
statute, rule or regulation applicable to Seller, or any of its assets, which violation, individually or in

assuming that this Agreement constitutes a valid and binding agreement of Seller and subject to the receipt
of Buyer's Required Regulatory Approvals, constitutes a valid and binding agreement of each of Parent and
Buyer, enforceable against each of Parent and Buyer in accordance with its terms, except that such
enforceability may be limited by applicable bankruptcy, insolvency, reorganization, fraudulent conveyance,
moratorium or other similar laws affecting or relating to enforcement of creditors' rights generally or
general principles of equity.

5.3.     CONSENTS AND APPROVALS; NO VIOLATION.

(a)      Except as set forth in Schedule 5.3(a), and other than obtaining Buyer's Required Regulatory
Approvals, neither the execution and delivery of this Agreement by Buyer or Parent nor the purchase by
Buyer of the Purchased Interests pursuant to this Agreement will (i) conflict with or result in any breach
of any provision of the Certificate of Formation or operating agreement (or other similar governing
documents) of Buyer and Parent, (ii) require any consent, approval, authorization or permit of, or filing
with or notification to, any Governmental Authority, (iii)  result in a default (or give rise to any right
of termination, cancellation or acceleration) under any of the terms, conditions or provisions of any note,
bond, mortgage, indenture, agreement, lease or other instrument or obligation to which Buyer or Parent is a
party or by which any of its assets may be bound, except for such defaults (or rights of termination,
cancellation or acceleration) as to which requisite waivers or consents have been obtained or which would
not, individually or in the aggregate, have a material adverse effect on the ability of Buyer to perform
its obligations hereunder ("Buyer Material Adverse Effect") or (iv) violate any law, regulation, order,
judgment or decree applicable to Buyer, which violations, individually or in the aggregate, would create a
Buyer Material Adverse Effect.  Buyer has no Knowledge of any facts or circumstances that make it reasonably
likely that Buyer's Required Regulatory Approvals will not be obtained.

(b)      Except as set forth in Schedule 5.3(b) (the filings and approvals referred to in such Schedule are
collectively referred to as the "Buyer's Required Regulatory Approvals"), no declaration, filing or
registration with, or notice to, or authorization, consent or approval of any Governmental Authority is
necessary for the consummation by Buyer of the transactions contemplated hereby.

5.4.     AVAILABILITY OF FUNDS.  Buyer has sufficient funds available to it or has received binding written
commitments from third parties, true and complete copies of which it has provided to Seller, to provide
sufficient funds to pay the Purchase Price on the Closing Date and to enable Buyer timely to perform all of
its obligations under this Agreement and Ancillary Agreements, and Buyer has delivered to Seller evidence of
the availability of such sufficient funds.

5.5.     LEGAL PROCEEDING.  To the Knowledge of Buyer and Parent, there are no actions, suits or proceedings
pending against Buyer or Parent before any court, arbitrator or Governmental Authority which, individually or
in the aggregate, could reasonably be expected to have a Buyer Material Adverse Effect.  Neither Parent nor
Buyer is subject to any outstanding judgments, rules, orders, writs, injunctions or decrees of any court,
arbitrator or Governmental Authority which, individually or in the aggregate, could reasonably be expected
to have a Buyer Material Adverse Effect.

5.6.     WARN ACT.  Buyer does not intend with respect to the NMP-1 Assets to engage in a "plant closing" or
"mass layoff', as such terms are defined in the WARN Act within 60 days after the Closing Date.

5.7.     TRANSFER OF QUALIFIED DECOMMISSIONING FUNDS.  Except for the fact that NMP-1 in the hands of Buyer
may not be treated as a "nuclear power plant" within the meaning of Treasury Regulations Section 1.468A-1(b)
(4), Buyer will otherwise acquire and own a "qualifying interest" in NMP-1 within the meaning of Treasury
Regulations section 1.468A-1 and will, as the transferee, satisfy each of the requirements set forth in
Treasury Regulations Section 1.468A-6(b)(2) with respect to the Qualified Decommissioning Funds.

5.8.     TRANSFER OF QUALIFIED DECOMMISSIONING FUNDS.  Buyer or, if applicable Parent, will conform to the
restrictions on foreign ownership, control or domination contained in Sections 103d and 104d of the Atomic
Energy Act of 1954, as amended, 42 U.S.C. 2133(d) and 2134(d), as applicable, and the NRC's regulations in
10 C.F.R. 50.38.  Neither Parent nor Buyer is currently owned, controlled, or dominated by a foreign entity
and neither will become owned, controlled, or dominated by a foreign entity before the Closing Date of this
transaction.  Each of Parent and Buyer agrees to abstain from filing any applications with any federal or
state agency in connection with any proposed merger, acquisition or disposition of assets or similar business
combination that could result in foreign ownership, control, or domination of Buyer, Buyer's holding company
or affiliates that own or control it before the Closing Date of this transaction.  If regulatory approval
from the NRC for the transfer of licenses from Seller to Buyer has not been received prior to twenty days
before the Termination Date and any issues in the application to transfer related to NRC approval of Buyer's
foreign ownership, control or domination status have not been resolved by that time, Seller may at their
option terminate this Agreement and Buyer will be liable to Seller for: (i) all of the costs that were
incurred in the sale of NMP-1 and (ii) any reduction in value received by Seller.  The reduction in value
will be defined as the greater of the difference between  the sale price to be received by Seller in this
Agreement and  (a) the sale price to have been received by Seller in the terminated transaction between
AmerGen as buyer and Niagara Mohawk and NYSEG as Seller (the AmerGen Transaction), or (b) the sale price
actually received by Seller in a subsequent sale completed within two (2) years of the date of termination
of this Agreement.  In calculating the value of the AmerGen Transaction, the sale price for each transaction
will be calculated as if 100% of both NMP-1 and NMP-2 were to be sold.  The reduction in value, with regard
to comparison with the AmerGen Transaction, will be the difference between the two sale prices.  For the
purposes of this section the sale price for each sale includes, without limitation, cash, power purchase
agreements, revenue sharing, and decommissioning.

5.9.     SELLER REPRESENTATIONS AND WARRANTIES.  As of the date hereof, neither Buyer nor Parent has any
knowledge of any breaches of any of Seller's representations or warranties or of any Pre-Closing Breaches.

5.10.    FINANCIAL STATEMENTS.Prior to the execution of this Agreement, Buyer has delivered to Seller true
and complete copies of the unaudited balance sheet of Buyer as of the quarter ended September 30, 2000, and
the related unaudited statement of income and cash flows for such period.  Prior to Closing, Buyer will
deliver to Seller true and complete copies of the unaudited balance sheet of Buyer and the related unaudited
statement of income and cash flows, each as of the most recent quarter end available at the time of Closing.
Except as set forth in the notes thereto, all such financial statements (i) were and will be prepared from
the books and records of Buyer in accordance with generally accepted accounting principles consistently
applied, and (ii) fairly present or will fairly present the financial condition and results of operations of
Buyer as of the respective dates thereof and for the respective periods covered thereby.

                                                    ARTICLE VI
                                             COVENANTS OF THE PARTIES

6.1.     CONDUCT OF BUSINESS RELATING TO THE NMP-1 ASSETS.

(a)      Except as described in Schedule 6.1 or to the extent Buyer otherwise consents in writing, during the
period from the date hereof to the Closing Date, Seller (i) shall operate the NMP-1 Assets in the ordinary
course consistent with Good Utility Practices and in accordance with all commitments made by NMPC to the NRC
as such commitments may be modified consistent with current industry practices; it being understood that (A)
any actions deemed reasonably necessary in the operation of the NMP-1 Assets in accordance with Good Utility
Practices shall be deemed to be in the ordinary course unless such actions materially impair the value, rated

and (B) the capital budget provided to Buyer, dated November 1, 2000, is not inconsistent with such standard;
(ii) shall use Commercially Reasonable Efforts to preserve intact the NMP-1 Assets and preserve the goodwill

any Governmental Authority, prior to the Closing Date, without the written consent of Buyer, which consent
shall not be unreasonably withheld, Seller will not with respect to the NMP-1 Assets:

         (i)      make any material change in the levels of Inventories customarily maintained by Seller
with respect to the NMP-1 Assets;

         (ii)     except for Permitted Encumbrances, sell, lease (as lessor), pledge, encumber, restrict,

assets used, consumed or replaced in the ordinary course of business consistent with Good Utility Practices;

         (iii)    modify, amend or voluntarily terminate prior to the expiration date thereof any of Seller's
Agreements and agreements listed in Schedule 4.8 (or any other agreement to the extent any such extension or
amendment thereof would require the agreement to be disclosed on Schedule 4.8) or any material Permit or
Environmental Permits or waive any default by, or release, settle or compromise any claim against, any other
Party thereto, other than (a) in the ordinary course of business, to the extent consistent with Good Utility
Practices, (b) with cause, to the extent consistent with Good Utility Practices or (c) as may be required
in connection with Seller's obligations to Buyer under this Agreement;

         (iv)     vary in any material respect from past practice in the timing and extent of
commitments to purchase nuclear fuel; provided, however, that Seller shall not extend or amend Fuel
Contracts;

insurance companies insurance in such amounts and against such risks and losses as are customary for such
assets and businesses;

         (vii)    enter into any requirements contract for goods or any commitment or contract
for non-employment related services, in either case not addressed in clauses (i) through (vi) above, that
will be delivered or provided after June 30, 2001 or such other date that the Parties mutually agree to be
the date on which the Closing is expected to occur that exceeds $100,000 per annum in the aggregate, unless
such commitment or contract is terminable by NMPC (or after the Closing Date by Buyer) without further
liability, upon not more than 60 days notice; and

         (viii)   agree to enter into any of the transactions set forth in the foregoing paragraphs
(i) through (vii).

(b)      A committee comprised of one or more senior representatives designated by Seller and one or more
senior representatives designated by Buyer (the "Transition Committee") will be established as soon as
practicable after the execution of this Agreement to permit Buyer to observe the operation of the NMP-1
Assets and to facilitate the transfer of the NMP-1 Assets to Buyer at the Closing.  The Transition Committee
will be kept fully apprised by NMPC of all NMP-1 management and operating developments.  The Transition
Committee shall have reasonable access to the management and Nuclear Oversight Committee of the Board of
Directors of NMPC.  The Transition Committee shall be accountable directly to the respective chief executive
officers of Buyer and Seller and shall from time to time report its findings to the senior management of
Seller and Buyer.

(c)      Between the date of this Agreement and the Closing Date, in the interest of cooperation between
Seller and Buyer and to permit informed action by Buyer regarding its rights pursuant to Section 6.1(a), the
Parties agree that at the sole responsibility and expense of Buyer, and subject to compliance with all
applicable NRC rules and regulations, Seller will permit designated Buyer Representatives ("Observers")
of Buyer to observe all operations of such Seller that relate to the NMP-1 Assets, and such observation
will be permitted on a cooperative basis in the presence of personnel of Seller but not restricted to the
normal business hours of Seller; provided, however, that such Observers and their actions shall not
interfere with the operation of NMP-1.  Buyer's Observers may recommend or suggest to management that
actions be taken or not be taken by Seller; provided, however, that Seller will not be under any
obligation to follow any such recommendations or suggestions and Seller shall be entitled, subject to
this Agreement, to conduct its business in accordance with its own judgment and discretion.  Buyer's
Observers shall have no authority to bind or make agreements on behalf of Seller; to conduct discussions
with or make representations to third parties on behalf of Seller; or to issue instructions to or direct
or exercise authority over Seller or any of Seller's officers, employees, advisors or agents.

6.2.     ACCESS TO INFORMATION.

(a)      In addition to the rights granted by Sections 6.1(b) and (c), between the date of this Agreement
and the Closing Date, Seller will, during ordinary business hours and upon reasonable notice and subject
to compliance with all applicable NRC rules and regulations (i) give Buyer and Buyer Representatives
reasonable access to all books, records, plants, offices and other facilities and properties constituting
the NMP-1 Assets; (ii) permit Buyer to make such reasonable inspections thereof as Buyer may reasonably
request, other than Phase II environmental site assessments (which have been conducted prior to the date
hereof); (iii) furnish Buyer with such financial and operating data and other information with respect
to the NMP-1 Assets as Buyer may from time to time reasonably request; (iv) furnish Buyer a copy of each
material report, schedule or other document filed or received by it since the date hereof with respect to
the NMP-1 Assets with the SEC, NRC, FERC, NYPSC or any other Governmental Authority having jurisdiction
over the NMP-1 Assets; provided, however, that (A) any such investigation shall be conducted in such a
manner as not to interfere unreasonably with the operation of the NMP-1 Assets, (B) Seller shall not be
required to take any action which would constitute a waiver of the attorney-client privilege and (C)
Seller need not supply Buyer with any information that Seller is legally prohibited to supply.  NMPC
will provide Buyer or Buyer's Representatives with access to the Transferred Employee Records that it
has, but NMPC shall not be required to provide access to other employee records or medical information
unless required by law or specifically authorized by the affected employee.  Notwithstanding anything
in this Section 6.2 to the contrary, NMPC will only furnish or provide such access to Transferred Employee
Records and personnel and medical records as is required by law, legal process or subpoena (other than data
concerning salaries and benefits, dates of birth, dates of hire and other information used to calculate
pension benefits which shall be provided).  NMPC shall keep Buyer generally informed as to the status
of all material negotiations with collective bargaining representatives concerning provisions of a
successor collective bargaining agreement that would affect Transferred Employees.

(b)      Buyer and Seller acknowledge that all information furnished to or obtained by Buyer or Buyer
Representatives pursuant to this Section 6.2 shall be subject to the provisions of the Confidentiality
Agreement and shall be treated as "Proprietary Information" (as defined in Section 1.1).

(c)      Following the Closing Date and subject to all applicable NRC rules and regulations, each Party
and its respective Representatives shall have reasonable access to all of the books and records relating
to the NMP-1 Assets, including all Transferred Employee Records or other personnel and medical records
required by law, legal process or subpoena, in the possession of the other Party or Parties to the extent
that such access may reasonably be required by such Party in connection with the Assumed Liabilities and
Obligations or the Excluded Liabilities, or other matters relating to or affected by the operation of the
NMP-1 Assets.  Such access shall be afforded by the Party or Parties in possession of such books and records
upon receipt of reasonable advance notice and during normal business hours.  The Party or Parties
exercising this right of access shall be solely responsible for any costs or expenses incurred by it or
them pursuant to this Section 6.2(c).  If the Party or Parties in possession of such books and records
shall desire to dispose of any such books and records, such Party or Parties shall, prior to such
disposition, give the other Party or Parties a reasonable opportunity at such other Party's or Parties'
expense, to segregate and remove such books and records as such other Party or Parties may select.
Notwithstanding the foregoing, the right of access to medical records and other confidential employee
records shall be subject to all applicable legal requirements.

(d)      Seller agrees (i) not to release any Person (other than Buyer) from any confidentiality agreement
now existing with respect to the NMP-1 Assets, or waive or amend any provision thereof, and (ii) to assign
any rights arising under any such confidentiality agreement (to the extent assignable) to Buyer.

(e)      Notwithstanding the terms of the Confidentiality Agreements and Section 6.2(b) above, the Parties
agree that prior to the Closing Buyer may reveal or disclose Proprietary Information to any other Persons
in connection with Buyer's financing and risk management of the NMP-1 Assets, and, to the extent that
Seller consents, which consent shall not be unreasonably withheld, to existing and potential customers
and suppliers, and to such Persons with whom Buyer expects it may have business dealings regarding the
NMP-1 Assets from and after the Closing Date; provided, however, that all such Persons agree in writing
to maintain the confidentiality of the Proprietary Information on substantially the same terms and
conditions of their respective Confidentiality Agreements.

(f)      Except as may be permitted in the Confidentiality Agreements or during the course of Buyer's due
diligence investigation of the NMP-1 Assets prior to the date hereof, Buyer agrees that, prior to the Closing
Date, it will not contact any vendors, suppliers, employees, or other contracting parties of Seller or
Seller's Affiliates with respect to any aspect of the NMP-1 Assets or the transactions contemplated hereby,
without the prior written consent of Seller, which consent shall not be unreasonably withheld.

(g)      Upon Buyer's or Seller's (as the case may be) prior written approval (which approval shall not be
unreasonably withheld or delayed) Seller or Buyer (as the case may be) may provide Proprietary Information of
the other Party to the SEC, NRC, FERC, NYPSC or any other Governmental Authority having jurisdiction over the
NMP-1 Assets or any stock exchange, as may be necessary to obtain Seller's Required Regulatory Approvals or
Buyer's Required Regulatory Approvals, respectively, or to comply generally with any relevant law, rule or
regulation.  The disclosing Party shall seek confidential treatment for the Proprietary Information provided
to any such Governmental Authority and the disclosing Party shall notify the other Party as far in advance
as practical of its intention to release to any Governmental Authority any such Proprietary Information.

(h)      The Parties agree that the Confidentiality Agreement shall remain in place until the Closing Date.
Thereafter, the Parties agree that any restrictions contained in the Confidentiality Agreement with respect
to Buyer's disclosure of Proprietary Information shall terminate, other than with respect to the Proprietary
Information of Seller that does not relate to the NMP-1 Assets.  The Parties further agree that after the
Closing Date, Seller shall keep confidential all Proprietary Information provided by Buyer or which Seller
possesses with respect to the NMP-1 Assets, to the extent permitted by law and to the same extent as
provided in the Confidentiality Agreement applicable to it, but without limitation as to duration.

6.3.     EXPENSES. Except to the extent specifically provided herein, whether or not the transactions
contemplated hereby are consummated, all costs and expenses incurred in connection with this Agreement and
the transactions contemplated hereby, including the cost of legal, technical and financial consultants and
the cost of filing for and prosecuting applications for Required Regulatory Approvals, shall be borne by the
Party incurring such costs and expenses.  Notwithstanding anything to the contrary herein, Buyer will pay
the cost of all filing fees under the HSR Act.

6.4.     FURTHER ASSURANCES; COOPERATION.

(a)      Subject to the terms and conditions of this Agreement, each of the Parties hereto will use
Commercially Reasonable Efforts to take, or cause to be taken, all action, and to do, or cause to be done,
all things necessary, proper or advisable under applicable laws and regulations to consummate and make
effective the sale of the Purchased Interests pursuant to this Agreement, including without limitation using
Commercially Reasonable Efforts to ensure satisfaction of the conditions precedent to each Party's
obligations hereunder, including, without limitation, all regulatory approvals.  Notwithstanding anything in
the previous sentence to the contrary, Seller and Buyer shall use Commercially Reasonable Efforts to obtain
all Permits and Environmental Permits necessary for Buyer to acquire and operate the NMP-1 Assets.  Neither
Buyer nor Seller will, without the prior written consent of the other, advocate, take or fail to take any
action which would reasonably be expected to prevent or materially impede, interfere with or delay the
transactions contemplated by this Agreement or which could reasonably be expected to cause, or to contribute
to causing, the other to receive less favorable regulatory treatment than that sought by the other.  Buyer
further agrees that prior to the Closing Date, neither it nor its Affiliates will enter into any other
contract to acquire, nor acquire, electric generation facilities or uncommitted generation capacity if the
proposed acquisition of such additional electric generation facilities or uncommitted generation capacity
are reasonably likely to prevent or materially interfere with the transactions contemplated by this
Agreement; provided, however, that nothing herein shall prohibit Buyer or its Affiliates from entering into
any contract to acquire from any co-tenant the undivided interest of such co-tenant in NMP-2 pursuant to
the option granted by Buyer to such co-tenant in the NMP-2 Asset Purchase Agreement for a period of 30 days
after the date hereof (such acquisition being referred to herein as an "Additional Co-Tenant Interest
Acquisition"); provided, further, that all regulatory filings with respect to such Additional Co-Tenant
Interest Acquisition shall only be made following the Closing unless Seller determines that such Additional
Co-Tenant Interest Acquisition is not reasonably likely to materially delay the consummation of the
transactions contemplated by this Agreement.

(b)      From time to time after the Closing Date, without further consideration, Seller will execute and
deliver such documents to Buyer as Buyer may reasonably request, at Buyer's expense, in order to more
effectively consummate the sale and purchase of the Purchased Interests or to more effectively vest in
Buyer such title to the NMP-1 Assets as is provided for in Section 4.7 subject to the Permitted Encumbrances.
Seller shall cooperate with Buyer, at Buyer's expense, in Buyer's efforts to cure or remove any Permitted
Encumbrances that Buyer reasonably deems objectionable.  From time to time after the Closing Date, without
further consideration, Buyer will, at its own expense, execute and deliver such documents to Seller as
Seller may reasonably request in order to evidence Buyer's assumption of the Assumed Liabilities and
Obligations.

(c)      The Parties shall cooperate with each other to facilitate the transition of the information systems,
computer applications and processing of data at the Facilities.

(d)      To the extent that Seller's rights under Seller's Agreement may not be assigned without the consent
of another Person which consent has not been obtained, this Agreement shall not constitute an agreement to
assign the same if an attempted assignment would constitute a breach thereof or be unlawful, and Seller, at
its expense, shall use Commercially Reasonable Efforts to obtain any such required consent(s) as promptly as
possible.  Seller and Buyer agree that if any consent to an assignment of Seller's Agreement shall not be
obtained or if any attempted assignment would be ineffective or would impair Buyer's rights and obligations
under the applicable Seller's Agreement so that Buyer would not in effect acquire the benefit of all such
rights and obligations, Seller, to the maximum extent permitted by law and such Seller's Agreement, shall
after the Closing appoint Buyer to be Seller's representative and agent with respect to such Seller's
Agreement, and Seller shall, to the maximum extent permitted by law and such Seller's Agreement, enter
into such reasonable arrangements with Buyer as are necessary to provide Buyer with the benefits and
obligations of such Seller's Agreement.  Seller and Buyer shall cooperate and shall each use Commercially
Reasonable Efforts after the Closing to obtain an assignment of such Seller's Agreement to Buyer.

(e)      Seller agrees to provide such services to Buyer for up to two years following the Closing as are
reasonably required to the extent necessary to ensure the continuity of support for NMP-1 and the orderly
completion of projects or other work in progress that would be adversely affected if those services were
interrupted.  Buyer and Seller will agree, as promptly as practicable, following the date hereof, on the
nature of such services, which shall be agreed upon in a service agreement.  Seller will be reimbursed for
all its costs, including development costs, in accordance with procedures to be mutually agreed upon by
Seller and Buyer or on an alternative cost reimbursement basis as mutually agreed by Seller and Buyer.

6.5.     PUBLIC STATEMENTS.  Until thirty (30) days following the Closing Date, the Parties shall not issue
any press release or file any public disclosure with the SEC with respect to this Agreement or the
transactions contemplated hereby without first affording the non-disclosing Party the opportunity to review
and comment on such disclosure.

each other as to the appropriate time of filing such notifications and shall agree upon the timing of such
filings, to respond promptly to any requests for additional information made by either of such agencies.

with FERC by the relevant date set forth on Schedule 6.6.  Prior to Buyer's submission of such application
with FERC, Buyer shall submit such application to Seller for review and comment and Buyer shall consider any
revisions reasonably requested by Seller.  Buyer shall be solely responsible for the cost of preparing and
filing this application, any petition(s) for rehearing, or any reapplication(s).  Each Party will bear its
own costs of the preparation and review of any such filings.

(e)      As promptly as practicable after the date of this Agreement, Buyer and Seller shall file with NRC an
application requesting consent under Section 184 of the Atomic Energy Act and 10 C.F.R. 50.80 for the

other related approvals.  In fulfilling their respective obligations set forth in the immediately preceding
sentence, each of Buyer and Seller shall use its Commercially Reasonable Efforts to effect any such filing by
the relevant date set forth on Schedule 6.6.  Each Party will bear its own costs of the preparation of any
such filing and NRC fees shall be shared equally by each Party.

(f)      Seller and Buyer shall cooperate with each other and promptly prepare and file notifications with,
and request Tax clearances from, state and local taxing authorities in jurisdictions in which a portion of
the Purchase Price may be required to be withheld or in which Buyer would otherwise be liable for any Tax

(g)      Seller and Buyer shall cooperate with each other and, as promptly as practicable after the date of

Regulatory Approvals) or required by the terms of any note, bond, mortgage, indenture, deed of trust,
license, franchise, permit, concession, contract, lease or other instrument to which any Seller or Buyer is
a party or by which any of them is bound.  The Parties shall respond promptly to any requests for additional
information made by such agencies, and use their respective Commercially Reasonable Efforts to cause
regulatory approval to be obtained at the earliest possible date after the date of filing.  Each Party will
bear its own costs of the preparation and review of any such filing.  Seller and Buyer shall have the right
to review in advance all characterizations of the information relating to the transactions contemplated by
this Agreement which appear in any filing made in connection with the transactions contemplated hereby and
the filing Party shall incorporate into any filing any revisions reasonably requested by the non-filing
Party.

(h)      Buyer shall have the primary responsibility for securing the transfer, reissuance or procurement of
the Permits and Environmental Permits (other than Transferable Permits) effective as of the Closing Date.
Seller shall cooperate with Buyer's efforts in this regard and assist in any transfer or reissuance of a
Permit or Environmental Permit held by Seller or the procurement of any other Permit or Environmental Permit
when so requested by Buyer.  In the event that Buyer is unable, despite its Commercially Reasonable Efforts,
to obtain a transfer or reissuance of one or more Transferable Permits as of the Closing Date, Buyer may use
the Permits issued to Seller, provided (i) such use is not unlawful, (ii) Buyer notifies Seller prior to the
Closing Date, (iii) Buyer continues to make Commercially Reasonable Efforts to obtain a transfer or
reissuance of such Permits after the Closing Date, and (iv) Buyer indemnifies Seller for any losses, claims
or penalties suffered by Seller in connection with the Transferable Permit that is not transferred or
reissued as of the Closing Date resulting from Buyer's ownership of the NMP-1 Assets following the Closing
Date.  In no event shall Buyer use or otherwise rely on a Transferable Permit issued to Seller beyond one
year after the Closing Date.

6.7.     BROKERAGE FEES AND COMMISSIONS.  Seller and Buyer each represent and warrant to the other that,
other than with respect to fees and commissions of J.P. Morgan & Co., Inc., which shall be the sole
responsibility of Seller, and of Barrington Energy Partners, LLC, which shall be the sole responsibility of
Parent and Buyer, no broker, finder or other Person is entitled to any brokerage fees, commissions or
finder's fees in connection with the transaction contemplated hereby by reason of any action taken by the
Party making such representation.  Seller and Buyer will pay to the other or otherwise discharge, and will
indemnify and hold the other harmless from and against, any and all claims or liabilities for all brokerage
fees, commissions and finder's fees incurred by reason of any action taken by the indemnifying party.

6.8.     TAX MATTERS.

(a)      All transfer taxes, New York State and local sales and use taxes incurred in connection with this
Agreement and the transactions contemplated hereby shall be borne by Buyer.  Buyer will file, to the extent
required by applicable law, all necessary Tax Returns and other documentation with respect to all such
transfer or sales taxes, and Seller will be entitled to review such returns in advance and, if required by
applicable law, will join in the execution of any such Tax Returns or other documentation.  Prior to the
Closing Date, Buyer will provide to Seller, to the extent possible, an appropriate exemption certificate in
connection with this Agreement and the transactions contemplated hereby, due from each applicable taxing
authority.

(b)      With respect to Taxes to be prorated in accordance with Section 3.5 of this Agreement, Buyer shall
prepare and timely file all Tax Returns required to be filed after the Closing with respect to the NMP-1
Assets, if any, and shall duly and timely pay all such Taxes shown to be due on such Tax Returns.  Buyer's
preparation of any such Tax Returns shall be subject to Seller's approval, which approval shall not be
unreasonably withheld.  Buyer shall make such Tax Returns available for Seller's review and approval no
later than fifteen (15) Business Days prior to the due date for filing such Tax Return.  Not less than five
(5) Business Days prior to the due date of any such Tax Return, Seller shall pay to Buyer a portion of the
amount shown as due on such Tax Return as determined in accordance with Section 3.5 of this Agreement in
proportion to Seller's Proportionate Ownership.

(c)      Buyer and Seller shall provide the other Parties with such assistance as may reasonably be requested
by the other Party in connection with the preparation of any Tax Return, any audit or other examination by
any taxing authority, or any judicial or administrative proceedings relating to liability for Taxes, and each
will retain and provide the requesting Party with any records or information which may be relevant to such
return, audit or examination, proceedings or determination.  Any information obtained pursuant to this
Section 6.8(c) or pursuant to any other Section hereof providing for the sharing of information or review of
any Tax Return or other schedule relating to Taxes shall be kept confidential by the Parties hereto.

(d)      In the event that a dispute arises between Seller and Buyer as to the amount of Taxes, the Parties
shall attempt in good faith to resolve such dispute, and any so agreed amount shall be paid to the
appropriate party.  If such dispute is not resolved within 30 days thereafter, the Parties shall submit the
dispute to the Independent Accounting Firm for resolution, which resolution shall be final, conclusive and
binding on the Parties.  Notwithstanding anything in this Agreement to the contrary, the fees and expenses
of the Independent Accounting Firm in resolving the dispute shall be borne fifty percent (50%) by Seller and
fifty percent (50%) by Buyer.  Any payment required to be made as a result of the resolution of the dispute
by the Independent Accounting Firm shall be made within ten days after such resolution, together with any
interest determined by the Independent Accounting Firm to be appropriate.

(e)      (i)     Buyer understands that:

         (A)     The facilities listed in Schedule 6.8(e) hereto (the "Pollution Control Facilities")
have been financed, and refinanced, in whole or in part, with the proceeds of the issuance and sale of the
 Pollution Control Bonds the interest on which, with certain exceptions, is excludable from gross income
for purposes of federal income taxation; and Seller are the economic obligors and conduit borrowers in
respect of the Pollution Control Bonds;

         (B)     The basis for the federal income tax exclusion for interest paid to bondholders of the
Pollution Control Bonds ("PC Bondholders") is the use of the Pollution Control Facilities for the purpose
of (I) the abatement or control of atmospheric pollution or contamination, (II) the abatement or control of
water pollution or contamination, (III) sewage disposal and/or (IV) the disposal of solid waste, as provided
in the Internal Revenue Code of 1954, as amended, and the Code, such qualifying purposes being discussed
in more detail in paragraph (ii) below;

         (C)     The use of the Pollution Control Facilities for a purpose other than the qualifying purposes
indicated in subclause (B) above and Section 6.8(e)(ii) hereunder may cause (I) the interest paid on the
Pollution Control Bonds to be includable in the federal gross income of the PC Bondholders, possibly with
retroactive effect, unless remedial action is taken to promptly redeem or defease the Pollution Control Bonds
or any portion thereof, and/or (II) the deductibility of Seller's payment of interest on the Pollution
Control Bonds to be disallowed pursuant to Section 150(b) of the Code; and

         (D)     Any breach by Buyer of its obligations under this subsection could result in the incurrence
by Seller of additional costs and expenses, including by way of example, but not by limitation, an increase
in the rate of interest paid to the PC Bondholders, liability to the PC Bondholders for their failure to
include interest paid on the Pollution Control Bonds in each one's respective federal gross income in the
event of a final determination of taxability by the IRS, loss of the interest deduction to Seller under Code
section 150(b) and transaction costs relating by way of example but not by way of limitation to any
refinancing, redemption, defeasance of or tender for all or part of the Pollution Control Bonds, and Buyer
shall indemnify Seller for such additional costs and expenses incurred by Seller solely as a result of any
breach by Buyer of its covenants in Sections 6.8(e)(ii) or (iii).

         (ii)     Except as otherwise provided in this paragraph, Buyer shall not use, or permit the use of,
the Pollution Control Facilities for any purpose other than their current use and in accordance with the
respective tax compliance documents or non-arbitrage certificates for each of the Pollution Control Bonds, or
for (x) abating or controlling atmospheric or water pollution or contamination by removing, altering,
disposing of or storing pollutants, contaminants, waste or heat, all as contemplated in U.S. Treasury
Regulations Section 1.103-8(g) or its successor Income Tax Regulations; (y) the collection, storage,
treatment, utilization, processing or final disposal of solid waste, all as contemplated in U.S. Treasury
Regulations Section 1.103-8(f) or its successor Income Tax Regulations; or (z) the collection, storage,
treatment, utilization, processing or final disposal of sewage, all as contemplated in U.S. Treasury
Regulations Section 1.103-8(f) or its successor Income Tax Regulations; unless Buyer has obtained at its
own expense an opinion addressed to Seller of nationally recognized bond counsel reasonably acceptable to
Seller ("Bond Counsel") that such change in use to a nonqualifying one will not impair (A) the exclusion from
gross income of the interest on any issue of Pollution Control Bonds for Federal income tax purposes or (B)
the deductibility of Seller's payments of interest based on the restrictions in Section 150(b) of the Code.
For purposes of this subsection, an abandonment of the Pollution Control Facilities shall be considered a
"change in use"; provided, however, suspending the operation of the Pollution Control Facilities or any part
thereof on a temporary basis so that the components thereof can be reactivated and used for the qualifying
purposes for which the Pollution Control Bonds were issued, shall not be considered a "change in use."

         (iii)    Buyer shall not sell or transfer any portion of the Pollution Control Facilities unless
Buyer's transferee covenants in writing for the benefit of Seller to comply with and to satisfy the
conditions of the subsection (e) with respect to transferee's ownership and use of the Pollution Control
Facilities.  Buyer's obligation on the covenants contained in this subsection (e) shall survive any such
sale or transfer of the Pollution Control Facilities, and in the event of a violation of such covenants,
Buyer and Buyer's transferee (and all such subsequent transferees) shall be jointly and severally liable to
Seller on Buyer's obligations hereunder.  Any contract implementing transfer of the Pollution Control
Facilities shall contain the covenants of this subsection (e).

(f)      [intentionally left blank]

(g)      The Parties agree that, for U.S. tax purposes (and not for other purposes, which are governed by
Section 3.4), the Purchase Price shall be allocated on a basis consistent with Section 1060 of the Code and
the Treasury Regulations thereunder.  Each of Buyer and Seller agree to file Internal Revenue Service Form
8594 (Asset Acquisition Statement Under Section 1060), and all federal, state, local and foreign Tax Returns,
in accordance with such allocations.  Each of Buyer and Seller agree to provide the other promptly with any
information required to complete Form 8594.  Buyer and Seller shall notify and provide the other with
reasonable assistance in the event of an examination, audit or other proceeding regarding the allocation of
the Purchase Price pursuant to this section.  Buyer and Seller shall not take any position in any tax
return, tax proceeding or audit that is inconsistent with such allocation without the consent of the other
Party.

6.9.     ADVICE OF CHANGES.  Prior to the Closing Date, each Party will promptly advise the other in writing
of any change or discovery occurring after the date hereof that would constitute a material breach of any
representation, warranty or covenant or a Pre-Closing Breach of the advising or other Party under this
Agreement.  If a Party advises the other Party of any such matter with respect to a breach of the advising
Party (other than a Pre-Closing Breach), the other Party shall have the right to terminate this Agreement in
accordance to Sections 9.1(e) or (f) as the case may be.  If a Party advises the other Party of any such
matter with respect to a breach by the other Party (other than a Pre-Closing Breach), the advising Party
shall have the right to terminate this Agreement in accordance with Section 9.1(e) or (f) as the case may be.
If a Party fails to exercise its termination right, the written notice under this Section 6.9 will be deemed
to have amended this Agreement, including the appropriate schedule, or to have qualified the representations
and warranties contained in Articles IV and V.  Seller shall be entitled to amend, substitute or otherwise
modify Seller's Agreement to the extent that Seller's Agreement expires by its terms prior to the Closing
Date or is terminable without liability to Buyer on or after the Closing Date, or if the terms and conditions
of such modified Seller's Agreement constituting the Assumed Liabilities and Obligations are on terms and
conditions not less favorable to Buyer than the original Seller's Agreement.

6.10.    EMPLOYEES.

(a)      Buyer agrees to offer employment to the employees of NMPC's work force employed at, or whose work
responsibilities involve principally the operation of, the Purchased Interests (in combination with the
acquisition of NMP-2 this work force currently consists of  approximately 619 management and 718 represented
employees).  Buyer and NMPC agree that Buyer shall be a successor within the meaning of the IBEW Collective
Bargaining Agreement.  The employment of employees who are represented by the IBEW shall continue in
accordance with the IBEW Collective Bargaining Agreement.

(b)      NMPC will make available to Buyer the IBEW Collective Bargaining Agreement.  With respect to Union
Employees on the Closing Date, Buyer will assume the IBEW Collective Bargaining Agreement as it relates to
such Union Employees employed at, or whose work responsibilities involve principally the operation of, the
Purchased Interests and shall agree and become party to and bound by the terms and conditions of the IBEW
Collective Bargaining Agreement including, but not limited to, the obligation of Buyer to recognize the IBEW
as the collective bargaining agent of such employees.  A Union Employee shall be entitled to retain his or
her seniority or receive credit for service with NMPC in connection with entitlement to wages, vacation,
benefits, and rights under the IBEW Collective Bargaining Agreement, provided that the Union Employee signs
an employee declaration that is acceptable  to NMPC, or otherwise indicates in a manner that is acceptable to
NMPC, that the Union Employee is voluntarily resigning his or her employment with NMPC to pursue employment
with Buyer without asserting a claim for a separation benefit from NMPC ("Employee Transition Agreement").
If a Union Employee fails to provide an Employee Transition Agreement acceptable to NMPC, the Union Employee
shall only be accorded such wages, vacation, seniority, benefits, and rights as are available to new
employees under the IBEW Collective Bargaining Agreement.

(c)      Each Non-Union Employee who is offered and accepts continued employment with Buyer will be referred
to herein as a "Transferred Non-Union Employee."  Each Union Employee who is offered and accepts employment
with Buyer will be referred to herein as a "Transferred Union Employee."  Collectively, Transferred Non-Union
Employees and Transferred Union Employees shall be referred to herein as "Transferred Employees."

(d)      For the period commencing on the Closing Date and ending 12 months thereafter, and except as Buyer
and any Transferred Non-Union Employee may otherwise mutually agree, Buyer shall provide each Transferred
Non-Union Employee with total compensation including without limitation base pay, authorized overtime,
bonuses, and benefits provided under all applicable employee benefits plans and programs, and fringe benefit
arrangements (specifically excluding NMPC's education reimbursement program) (collectively, "Total
Compensation") which in the aggregate is substantially equivalent in value to the Transferred Non-Union
Employee's annualized TotalCompensation received from NMPC prior to Closing.  Buyer shall also:  (i) pay the
reasonable relocation costs of any Transferred Non-Union Employee who shall relocate at Buyer's request and,
(ii) maintain the defined benefit plan described in Section 6.10(h) for the period specified in that Section.

(e)      As of the Closing Date all Transferred Non-Union Employees shall cease to participate in the
employee welfare plans (as such term is defined in ERISA) maintained or sponsored by NMPC or its Affiliates
and shall, if applicable, commence participation in the welfare benefit plans of Buyer or its Affiliates (the
"Replacement Welfare Plans") that will provide benefits or coverage substantially similar to the benefits or
coverage provided to the Transferred Non-Union Employees under NMPC's plans and programs in effect for the
Transferred Non-Union Employees immediately prior to the Closing Date.  Buyer shall (i) waive all limitations
as to pre-existing condition exclusions and waiting periods with respect to the Transferred Non-Union
Employees under the Replacement Welfare Plans, other than, but only to the extent of, limitations or waiting
periods that were in effect with respect to such employees under the welfare plans maintained by NMPC and
that have not been satisfied as of the Closing Date, and (ii) provide each Transferred Non-Union Employee
with credit for any co-payments and deductibles paid prior to the Closing Date during a plan year under
NMPC's plan that has not ended as of the Closing Date, in satisfying any deductible or out-of-pocket
requirements under the Replacement Welfare Plans (on a pro-rata basis in the event of a difference in plan
years).

(f)      Buyer shall give all Transferred Non-Union Employees credit for all service with NMPC and its
Affiliates under all employee benefit plans, programs and arrangements and all fringe benefit plans,
programs, and arrangements of Buyer ("Replacement Benefit Plans") in which they become participants.
The service credit given is for purposes of eligibility, vesting and service related level of benefits,
but not benefit accrual (except as provided in the following sentence).  For purposes of benefit accrual,
Buyer shall give Transferred Non-Union Employees credit for all service with NMPC and its Affiliates under
all Replacement Benefit Plans, but the ultimate benefits provided under Replacement Benefit Plans may be
offset by the corresponding benefits previously provided by NMPC or benefit plans of NMPC, or by the
corresponding benefits accrued under the benefit plans of NMPC or otherwise committed to be provided by
NMPC in the future; provided, however, that such an offset shall not be permitted with respect to the
Replacement Defined Benefit Plan described in Section 6.10(h).

(g)      Buyer agrees to allow the Transferred Non-Union Employees, as of the Closing Date, to be eligible to
commence participation in a Buyer tax-qualified 401(k) plan that will provide benefits substantially similar
to the benefits provided to the Transferred Non-Union Employees under the NMPC tax-qualified 401(k) plan in
effect for Non-Union Employees immediately prior to the Closing Date ("NMPC Savings Plan").

         To the extent allowable by law and by the applicable NMPC plan, Buyer shall take any and all
necessary action to cause the trustee of any tax-qualified 401(k) plan of Buyer or its Affiliates in which
any Transferred Non-Union Employee becomes a participant to accept a direct "rollover" in cash of all or a
portion of said employee's "eligible rollover distribution" within the meaning of Section 402 of the Code
from the NMPC Savings Plan if requested to do so by the Transferred Non-Union Employee.  However, any
tax-qualified 401(k) plan of Buyer or its Affiliates accepting such a rollover shall not be required to
permit any investment to be made in Niagara Mohawk Holdings, Inc. common stock on behalf of any Transferred
Non-Union Employee after the Closing Date.  Notwithstanding anything in this paragraph to the contrary, if
Transferred Non-Union Employees are not entitled to distributions from the NMPC Savings Plan as a result of
being employed by Buyer, then either (i) the parties may negotiate a direct transfer from the NMPC Savings
Plan trust to Buyer's tax-qualified plan trust under such terms and conditions as are agreeable to both
parties or (ii) if the parties are unable to negotiate such an agreement, then Buyer agrees to provide NMPC,
in a timely manner, with such information as NMPC reasonably needs about the Transferred Non-Union Employees
in order for NMPC to administer the Transferred Non-Union Employees' benefits under the NMPC Savings Plan
(e.g., information about when the Transferred Non-Union Employees retire, die, terminate employment).

(h)      Effective as of the Closing Date, Buyer shall cause to be established a defined benefit pension plan
for the benefit of the Transferred Non-Union Employees (the "Replacement Defined Benefit Plan").  The
Replacement Defined Benefit Plan shall have the same terms as apply to the Transferred Non-Union Employees
under NMPC's qualified defined benefit plan ("NMPC's Defined Benefit Plan") as of the Closing Date; provided
that, except as required by law, no improvements for Transferred Non-Union Employees are made after the date
hereof and prior to the Closing Date without the written consent of Buyer, which consent shall not be
unreasonably withheld.  Buyer agrees to maintain such terms for Transferred Non-Union Employees for a period
of at least seven (7) years after the Closing Date (provided, however, that if changes in the law require
any such terms to be modified, Buyer may change such terms to the extent necessary to comply with such laws
as reasonably determined by the Buyer).

         The Transferred Non-Union Employees shall be given credit in the Replacement Defined Benefit Plan
for all service with and compensation from NMPC and its Affiliates as if it were service with and
compensation from Buyer for purposes of determining eligibility for benefits, the amount of any benefits or
benefit accruals, vesting, and service related levels of benefits under the Replacement Defined Benefit Plan.

         In connection with the foregoing, the following actions shall be taken as of the Closing Date:

         (A) At the time specified in subparagraph (C) below, NMPC shall cause to be transferred
             from NMPC's Defined Benefit Plan to the corresponding Replacement Defined Benefit Plan
             assets equal to (i) the Projected Benefit Obligation ("PBO"), as determined in
             accordance with the actuarial assumptions set forth in Schedule 6.10(h) (the
             "Assumptions"), attributable to the Transferred Non-Union Employees as of the Closing
             Date, plus (ii) interest at an annual rate that is equivalent to the discount rate set
             forth in the Assumptions for the period from the Closing Date to the date of the
             actual transfer of assets and adjusted for benefit payments under the NMPC's Defined
             Benefit Plan made pursuant to subparagraph (D) below; provided, however, that if NMPC
             is unable to transfer the amount required by this paragraph h(A)(i) and (ii), then:

             (I)  NMPC shall transfer an amount equal to the sum of the accumulated
                  benefit obligation ("ABO"), whether or not vested, as determined in
                  accordance with the Assumptions, and which is attributable to the
                  Transferred Non-Union Employees as of the Closing Date and the amount
                  described in paragraph h(A)(ii); and

             (II) NMPC shall pay to Buyer in cash the amount of the difference between
                  the amount described in paragraph h(A)(i) and (ii) and the amount
                  described in clause (I) above.

                  The transfer of either of the amounts described in this subparagraph (A) shall be made
                  in accordance with Section 414(l) of the Code and Treasury Regulation Section
                  1.414(l)-l, using the actuarial assumptions specified in Schedule 6.10(h).  The PBO and
                  ABO shall be calculated in accordance with the Assumptions and using an annual
                  interest rate credit equal to the "Interest Rate" (as that term is defined in the NMPC
                  Defined Benefit Plan) at the Closing Date.

         (B) All assets transferred under subparagraph (A) shall be transferred in cash, or in
             marketable securities that are reasonably acceptable to Buyer.

         (C) Within 45 days after the Closing Date, NMPC and Buyer shall file or cause to be filed
             any Forms 5310-A that may be required to be submitted to the IRS in connection with
             the transfer described in subparagraph (A).  The transfer described in subparagraph
             (A) shall be made as soon as practicable following the determination of the amount
             described in subparagraph (A), but in no event prior to the thirtieth (30th) day
             following the filing of such Forms 5310-A with the IRS or, in the event that the IRS,
             the PBGC or any other governmental entity raises any objections to the transfer, the
             date as of which the IRS, the PBGC or other governmental entity withdraws such
             objections or is satisfied that the terms of the transfer have been modified to the
             extent necessary to meet such objections.

         (D) Upon completion of the transfer under subparagraph (A), all benefit payments from the
             Replacement Defined Benefit Plan shall be the responsibility of Buyer.  Pending
             completion of the transfer under subparagraph (A), any benefits that would otherwise
             be payable to the Transferred Non-Union Employees under the Replacement Defined
             Benefit Plan shall be paid or continue to be paid out of the NMPC's Defined Benefit
             Plan, and the amount to be transferred under subparagraph (A) shall be reduced by the
             amount of such payments.  Pending the completion of such transfer, NMPC will cooperate
             with Buyer with respect to plan administration, including the disbursement of benefits.

         (E) Buyer agrees that it shall submit the  Replacement  Defined  Benefit Plan to the IRS for
             a determination  letter on its tax-qualified  status under Section 401(a) of the Code as
             soon as practicable after the Closing.

         NMPC agrees that it shall use Commercially Reasonable Efforts to accomplish the transfer of assets
described in subparagraph (A) of this Section 6.10; provided, however, that if NMPC determines in good faith
that it is unable to make such a transfer, then, notwithstanding the language in this Section 6.10, NMPC and
Buyer agree to negotiate a mutually agreeable resolution of the defined benefit plan issues in this Section.

(i)        Buyer and NMPC do not anticipate the issuance of any notices pursuant to the WARN Act.
Notwithstanding the foregoing, NMPC agrees to timely perform and discharge all requirements under the WARN
Act and under applicable state and local laws and regulations for the notification of employees arising from
the sale of the Purchased Interests to Buyer up to the Closing Date for those employees who will not become
Transferred Employees effective as of the Closing Date.  On or after the Closing Date, Buyer shall be
responsible for performing and discharging all requirements under the WARN Act and under applicable state
and local laws and regulations for the notification of employees with respect to the Purchased Interests.
At Closing, NMPC shall provide a certificate setting forth the number of employees who suffered an
"employment loss" at NMP-1 or NMP-2 as defined under the WARN Act in the ninety (90) days immediately
preceding the Closing Date.

(j)       NMPC is responsible for extending COBRA continuation coverage to all employees and former employees,
and qualified beneficiaries of such employees and former employees, who become or became entitled to such
COBRA continuation coverage on or before the Closing Date by reason of the occurrence of a qualifying event
on or before the Closing Date, including those for whom the Closing Date occurs during their COBRA election
period.  Buyer shall be responsible for providing COBRA continuation coverage only to Transferred Employees
and qualified beneficiaries of such employees who become entitled to such COBRA continuation coverage on or
after the Closing Date by reason of the occurrence of a qualifying event after the Closing Date.

(k)       NMPC shall remain responsible for paying Transferred Non-Union Employees for:  (a) all salary,
wages, and a pro rata portion of any bonuses or incentive compensation that were earned for time worked for
NMPC or NMPC's Affiliates prior to the Closing Date; and (b) all workers' compensation, disability benefits,
or other insurance benefits for which entitlement to payment is based upon events occurring prior to the
Closing Date including any incurred but unreported claims under employee benefit plans maintained by NMPC.
NMPC shall pay to Buyer as promptly as practicable following the Closing Date, but no later than the 45th
day, the cash equivalent for all vacation time for Transferred Non-Union Employees which has accrued as of
the Closing Date (holiday time shall not be included in such payment).  Seller shall remain responsible for
all vacation time for Transferred Union Employees which has accrued as of the Closing Date.

(l)       Individuals who are otherwise "Union Employees" or "Non-Union Employees" but who on any date are
not actively at work due to a leave of absence covered by the Family and Medical Leave Act, or due to any
other authorized leave of absence, shall nevertheless be treated as "Union Employees" or as "Non-Union
Employees," as the case may be, on such date if they are able to (i) return to work within the protected
period under the Family and Medical Leave Act or such other leave whichever is applicable, and (ii) perform
the essential functions of their job, with or without a reasonable accommodation.

(m)      For at least two years following the Closing Date, Buyer shall provide all Transferred Non-Union
Employees with retiree medical, mental health, prescription drug, and life insurance coverages (the
"Replacement Retiree Coverages") that are substantially similar to the NMPC retiree medical, mental health,
prescription drug, and life insurance coverages available to eligible Non-Union Employees who retire from
NMPC immediately prior to the Closing Date (the "NMPC Retiree Coverages").  Buyer shall (i) waive all
limitations as to pre-existing condition exclusions and waiting periods with respect to the Transferred
Non-Union Employees under the Replacement Retiree Coverages, other than, but only to the extent of
limitations or waiting periods that were in effect with respect to such employees under the NMPC Retiree
Coverages and that have not been satisfied as of the Closing Date, and (ii) provide each Transferred
Non-Union Employee with credit for any co-payments and deductibles paid prior to the Closing Date during a
plan year under each applicable NMPC's plan that has not ended as of the Closing Date, in satisfying any
deductible or out-of-pocket requirements under the Replacement Retiree Coverages (on a pro-rata basis in
the event of a difference in plan years).  Effective as of the Closing Date, NMPC shall have no
responsibility to provide retiree medical, mental health, prescription drug, or life insurance coverages
for any Transferred Employee.

(n)      Buyer shall pay to each Transferred Non-Union Employee who is hired by Buyer and whose employment is
terminated by Buyer or one of its Affiliates within eighteen months of the Closing Date a severance benefit
package equivalent to that which would have been provided to such individual upon such termination by NMPC
under the Niagara Mohawk Involuntary Severance Plan as in effect on the Closing Date had such individual
remained continuously employed by NMPC or its Affiliates and had been eligible for, and entitled to benefits
under, such plan on the date of such termination.

(o)      Buyer shall assume the obligations of Seller under the agreements listed on Schedule 6.10(o) hereto.

6.11.    RISK OF LOSS.

(a)      Prior to the Closing, Buyer shall not bear any risk of loss or damage to the property included in
the NMP-1 Assets.  Seller shall replace or repair any damage to the NMP-1 Assets in accordance with Good
Utility Practices, except as otherwise provided in paragraphs (b) or (c) below.

(b)      If, before the Closing, all or any portion of the NMP-1 Assets is taken by eminent domain or is the
subject of a pending or (to the Knowledge of Seller) contemplated taking which has not been consummated,
Seller shall notify Buyer promptly in writing of such fact.  If such taking would create a Material Adverse
Effect, Buyer and Seller shall negotiate in good faith to settle the loss resulting from such taking
(including, without limitation, by making a fair and equitable adjustment to the Purchase Price) and, upon
such settlement, consummate the transactions contemplated by this Agreement pursuant to the terms of this
Agreement.  If no such settlement is reached within sixty (60) days after Seller has notified Buyer of such
taking, then Buyer or Seller may terminate this Agreement pursuant to Section 9.1(f).

(c)      If, before the Closing, all or any portion of the NMP-1 Assets is damaged or destroyed by fire or
other casualty, Seller shall notify Buyer promptly in writing of such fact.  If such damage or destruction
would create a Material Adverse Effect and Seller has not notified Buyer of its intention to cure such damage
or destruction within fifteen (15) days after its occurrence, Buyer and Seller shall negotiate in good faith
to settle the loss resulting from such casualty (including, without limitation, by making a fair and
equitable adjustment to the Purchase Price) and, upon such settlement, consummate the transactions
contemplated by this Agreement pursuant to the terms of this Agreement.  If no such settlement is reached
within sixty (60) days after Seller has notified Buyer of such casualty, then Buyer may terminate this
Agreement pursuant to Section 9.1(f).

(d)      The provisions of Section 5-1311 of the New York General Obligations Law shall not apply to this
Agreement.

6.12.    DECOMMISSIONING FUNDS.

(a)      (i)  Between the date hereof and the Closing Date, Seller will make additional cash deposits from
time to time to its Qualified Decommissioning Fund and its Nonqualified Decommissioning Fund such that, on
the Closing Date Seller shall have accumulated assets in the Decommissioning Funds equal to the Qualified
Target, calculated on a Net Cash Value basis, in the Qualified Decommissioning Fund and the Nonqualified
Target in the Nonqualified Decommissioning Fund.

         (ii) At the Closing, Seller shall cause all of the assets of the Decommissioning Funds to be
transferred to the Trustee under the Post-Closing Decommissioning Trust Agreement.

(b)      The Parties shall not take any actions that would be inconsistent with the desired Tax
consequences of the transactions contemplated by this Agreement as set forth below:

         (i)  None of the Seller, its Qualified Decommissioning Fund or Buyer shall recognize any gain or
otherwise take into account any income for federal income tax purposes by reason of the transfer of the
assets of such Qualified Decommissioning Fund to the trustee under the Post-Closing Decommissioning Trust
Agreement.

         (ii) Seller will (I) determine its gain or loss by taking the difference between its Tax Basis in
the Purchased Interests (excluding the assets comprising its Qualified Decommissioning Fund) and its Purchase
Price as determined under Section 3.2 and Buyer's assumption of its percentage interest of Assumed
Liabilities and Obligations to the extent such Assumed Liabilities and Obligations are taken into account as
liabilities for federal income tax purposes (together "Amount Realized") (excluding for purposes of this
paragraph 6.12(b)(i), the decommissioning liability to the extent of the fair market value of the assets of
the Qualified Decommissioning Fund); and (II) take a current deduction in determining its taxable income for
its taxable year which includes the Closing Date in an amount equal to the total of any amounts treated as
realized by Seller, or otherwise recognized as income to Seller, as a result of Buyer's assumption of the
Decommissioning obligations with respect to the Purchased Interests.

         (iii)Seller will not be liable for any Tax on account of any built in-gain in Seller's Qualified
Decommissioning Fund.

         (iv) Buyer will not realize income as a result of its acquisition of the Purchased Interests except
to the extent that the fair market value of the Class I Assets (as defined in Temporary Regulations Section
1.338-6T(b)(1) and other than the assets comprising Seller's Qualified Decommissioning Fund) included as
part of the Purchased Interests exceeds the Purchase Price.

(c)      In the event that, during the period beginning on the date of this Agreement and ending on the
Closing Date, legislation or Treasury Regulations are enacted or promulgated or the IRS issues a private
letter ruling which is available to the Parties, revenue ruling, revenue procedure, announcement or notice,
or there has been a decision of a court of competent jurisdiction, that produces a benefit for the Buyer not
otherwise contemplated in Section 6.12(b)(i) and 6.12(b)(iv)  and is related to the transactions contemplated
in this Agreement, then, the Parties agree to negotiate in good faith an equitable sharing of any such
benefit.

6.13.    SPENT NUCLEAR FUEL FEES.  Except as provided in the third sentence of this paragraph and Sections
2.1(b) and 2.3(g), between the date hereof and the Closing Date, and at all times thereafter, Seller will

NMP-1 and sold prior to the Closing Date, and Buyer shall have no liability or responsibility therefor.
Buyer shall pay and discharge all fees and expenses associated with the nuclear fuel consumed in NMP-1 and
sold from and after the Closing Date, and Seller shall have no liability or responsibility therefor.  Buyer

of title to spent fuel.

6.14.    DEPARTMENT OF ENERGY DECONTAMINATION AND DECOMMISSIONING FEES.  Seller will continue to pay all
Department of Energy Decontamination and Decommissioning Fees relating to nuclear fuel purchased and consumed

issued after the Closing Date by the Department of Energy, as contemplated by its regulations at 10 C.F.R.
Part 766 implementing Sections 1801, 1802, and 1803 of the Atomic Energy Act.

6.15.    COOPERATION RELATING TO INSURANCE AND PRICE-ANDERSON ACT.  Until the Closing, NMPC will maintain in
effect the same level of property damage and liability insurance for the Facilities as in effect on the date
hereof.  NMPC shall cooperate with Buyer's efforts to obtain insurance, including insurance required under
the Price-Anderson Act or other Nuclear Laws, with respect to the NMP-1 Assets.  In addition, subject to the
satisfaction of Buyer's indemnification obligations under Section 8.1(a), NMPC agrees to use reasonable
efforts to assist Buyer in making any claims against pre-Closing insurance policies of NMPC that may provide
coverage related to Assumed Liabilities and Obligations.  Buyer agrees to indemnify NMPC for its reasonable
out of pocket expenses incurred in providing such assistance and cooperation and not to take any action which
shall adversely affect any residual rights of NMPC in such insurance policies.

6.16.    TAX CLEARANCE CERTIFICATES.  Seller and Buyer shall cooperate and use their Commercially Reasonable
Efforts to cause the tax clearance certificates described in Schedule 4.20 of this Agreement to be issued by

a private letter ruling request to be made jointly by Buyer and Seller in order to confirm the federal income
tax treatment desired by the Parties as set forth in Section 6.12(b)(i), (ii), and (iv).  All rulings
requested shall be consistent with private letter rulings issued as of the date of this Agreement by the IRS
with respect to the transfer of a Qualified Decommissioning Fund to a non-regulated buyer.  Neither Buyer nor
Seller will take any action to cause the IRS to fail to issue such private letter ruling.  The filing fees
payable in connection with such request shall be borne 50% by the Buyer and 50% by the Seller.

6.19.    DECOMMISSIONING.  Buyer hereby agrees to commit to the NYPSC as a part of receiving Buyer's Required
Regulatory Approvals to Decommission NMP-1 once the Site is no longer utilized for power generation, it being
understood for purposes of this Section 6.19 that the term Decommission shall include, but not be limited to,
all requirements of Nuclear Laws and Environmental Laws, including the applicable requirements of the Atomic
Energy Act and the NRC's rules, regulations, orders and pronouncements thereunder in effect on the date
hereof.

6.20.    OBLIGATION OF PARENT TO FUND BUYER UNDER NOTE.  In the event of the failure of Buyer to meet the Net
Worth Requirement or the Coverage Requirement (as defined in the Note referred to in Section 3.2 hereof)
prior to the date on which such Note is satisfied in full, the Parent shall be obligated (the "Capital
Obligation") no later than 5 days after receipt of notice from Seller to make an equity contribution or
otherwise adjust the capital structure of Buyer in order to cause Buyer to comply with such requirements in
order to avoid the occurrence of an Event of Default (as defined in such Note), which 5 days shall run
concurrently with the 5 day notice period set forth in Section 5(g) or 5(h) of such Note, as applicable.  In
the event of the failure by Parent to comply with its Capital Obligation, the Seller shall be entitled to the
remedy of specific performance against Parent, compelling Parent to comply with its Capital Obligation, and
Parent shall reimburse Seller for any expenses in connection with enforcing its rights under this Section
6.20.

                                                  INDEMNIFICATION

8.1.     INDEMNIFICATION.

(a)      Following the Closing, Buyer shall indemnify, defend and hold harmless Seller, its officers,
directors, employees, shareholders, Affiliates and agents (each, a "Seller Indemnitee") from and against any
and all claims, demands, suits, losses, liabilities, damages, obligations, payments, costs and expenses
(including, without limitation, the costs and expenses of any and all actions, suits, proceedings,
assessments, judgments, settlements and compromises relating thereto and reasonable attorneys' fees and
reasonable disbursements in connection therewith) (each, an "Indemnifiable Loss"), asserted against or
suffered by any Seller Indemnitee relating to, resulting from or arising out of (i) any breach by Buyer of
any representations and warranties which survive the Closing or any covenants contained in this Agreement,
(ii) the Assumed Liabilities and Obligations, (iii) any Third Party Claims against a Seller Indemnitee
arising out of or in connection with Buyer's ownership of or operation of NMP-1 and other NMP-1 Assets on or
after the Closing Date, (iv) any actions taken by Buyer (including, without limitation, the structure of the
transfer of the Decommissioning Funds contemplated by this Agreement), which shall result in tax consequences
to Seller which are different for Seller from those contemplated in Section 6.12(b)(i) and 6.12(b)(ii), or
(v) any tax consequences to Seller which results in a Tax liability to Seller on account of any built-in
gain in Seller's Qualified Decommissioning Fund.

(b)      Following the Closing, Seller shall indemnify, defend and hold harmless Buyer, its officers,
directors, members, employees, shareholders, Affiliates and agents (each, a "Buyer Indemnitee") from and
against any and all Indemnifiable Losses asserted against or suffered by any Buyer Indemnitee relating to,
resulting from or arising out of (i) any breach by Seller of the representations and warranties which
survive the Closing or any covenants contained in this Agreement, (ii) the Excluded Liabilities, (iii)
noncompliance by Seller with any bulk sales or transfer laws as provided in Section 10.11, (iv) any Third
Party Claims against a Buyer Indemnitee arising out of or in connection with Seller's ownership or operation
of the NMP-1 Assets on or prior to the Closing Date (other than any Third Party Claims that are Assumed
Liabilities), (v) any Third Party Claims against a Buyer Indemnitee arising out of or in connection with
Seller's ownership or operation of the Excluded Assets, (vi) all Taxes incurred by reason of any act of
Seller that either constitutes an act of "self-dealing" as defined in Treas. Reg. 1.468A-5(b)(2) or results
in the disqualification of the Qualified Decommissioning Funds under Treas. Reg. 1.468A-5 other than as a
result of the transfer contemplated by Section 5.7 hereof, or (vii) any claims or attachments of Seller or
any Seller creditor against the Decommissioning Funds after the Closing Date.

(c)      The expiration or termination of any representation or warranty shall not affect the Parties'
obligations under this Section 8.1 if the Indemnitee provided the Person required to provide indemnification
under this Agreement (the "Indemnifying Party") with proper notice of the claim or event for which
indemnification is sought prior to such expiration, termination or extinguishment.

(d)      Except to the extent otherwise provided in Article IX, the rights and remedies of Seller and Buyer
under this Article VIII are exclusive and in lieu of any and all other rights and remedies which Seller and
Buyer may have under this Agreement or otherwise for monetary relief, with respect to (i) any breach of or
failure to perform any covenant, agreement, or representation or warranty set forth in this Agreement, after
the occurrence of the Closing, or (ii) the Assumed Liabilities and Obligations or the Excluded Liabilities,
as the case may be.  The indemnification obligations of the Parties set forth in this Article VIII apply only
to matters arising out of this Agreement, excluding the Ancillary Agreements.  Any Indemnifiable Loss arising
under or pursuant to an  Ancillary Agreement shall be governed by the indemnification obligations, if any,
contained in the Ancillary Agreement under which the Indemnifiable Loss arises.

(e)      Notwithstanding anything to the contrary herein, no Party (including an Indemnitee) shall be
entitled to recover from any other Party (including an Indemnifying Party) for any liabilities, damages,
obligations, payments, losses, costs, or expenses under this Agreement any amount in excess of the actual
compensatory damages, court costs and reasonable attorney's and other advisor fees suffered by such Party.
Buyer and Seller waive any right to recover punitive, incidental, special, exemplary and consequential
damages arising in connection with or with respect to this Agreement including, but not limited to, losses
or damages caused by reason of unavailability of NMP-1, plant shutdowns or service interruptions, loss of
use, profits or revenue, inventory or use charges, cost of purchased or replacement power, interest charges
or cost of capital.  The provisions of this Section 8.1(e) shall not apply to indemnification for a Third
Party Claim.

8.2.     DEFENSE OF CLAIMS.

(a)      If any Indemnitee receives notice of the assertion of any claim or of the commencement of any claim,
action, or proceeding made or brought by any Person who is not a Party to this Agreement or any Affiliate of
a Party to this Agreement (a "Third Party Claim"), including but not limited to an information document
request or a notice of proposed disallowance issued by the Internal Revenue Service relating to a matter
covered by Section 5.7, with respect to which indemnification is to be sought from an Indemnifying Party, the
Indemnitee shall give such Indemnifying Party reasonably prompt written notice thereof, but in any event such
notice shall not be given later than twenty (20) calendar days after the Indemnitee's receipt of notice of
such Third Party Claim.  Such notice shall describe the nature of the Third Party Claim in reasonable detail
and shall indicate the estimated amount, if practicable, of the Indemnifiable Loss that has been or may be
sustained by the Indemnitee.  The Indemnifying Party will have the right to participate in or, by giving
written notice to the Indemnitee, to elect to assume the defense of any Third Party Claim at such
Indemnifying Party's expense and by such Indemnifying Party's own counsel, provided that the counsel for the
Indemnifying Party who shall conduct the defense of such Third Party Claim shall be reasonably satisfactory
to the Indemnitee.  The Indemnitee shall cooperate in good faith in such defense at such Indemnitee's own
expense.  If an Indemnifying Party elects not to assume the defense of any Third Party Claim, the Indemnitee
may compromise or settle such Third Party Claim over the objection of the Indemnifying Party, which
settlement or compromise shall conclusively establish the Indemnifying Party's liability pursuant to this
Agreement.

(b)      (i)      If, within twenty (20) calendar days after an Indemnitee provides written notice to the
Indemnifying Party of any Third Party Claims, the Indemnitee receives written notice from the Indemnifying
Party that such Indemnifying Party has elected to assume the defense of such Third Party Claim as provided in
Section 8.2 (a) , the Indemnifying Party will not be liable for any legal expenses subsequently incurred by
the Indemnitee in connection with the defense thereof; provided, however, that if the Indemnifying Party
shall fail to take reasonable steps necessary to defend diligently such Third Party Claim within twenty (20)
calendar days after receiving notice from the Indemnitee that the Indemnitee believes the Indemnifying Party
has failed to take such steps, the Indemnitee may assume its own defense and the Indemnifying Party shall be
liable for all reasonable expenses thereof.

         (ii)     Without the prior written consent of the Indemnitee, the Indemnifying Party shall not enter
into any settlement of any Third Party Claim which would lead to liability or create any financial or other
obligation on the part of the Indemnitee for which the Indemnitee is not entitled to indemnification
hereunder.  If a firm offer is made to settle a Third Party Claim without leading to liability or the
creation of a financial or other obligation on the part of the Indemnitee for which the Indemnitee is not
entitled to indemnification hereunder and the Indemnifying Party desires to accept and agree to such offer,
the Indemnifying Party shall give written notice to the Indemnitee to that effect.  If the Indemnitee fails
to consent to such firm offer within twenty (20) calendar days after its receipt of such notice, the
Indemnifying Party shall be relieved of its obligations to defend such Third Party Claim and the Indemnitee
may contest or defend such Third Party Claim.  In such event, the maximum liability of the Indemnifying
Party as to such Third Party Claim will be the amount of such settlement offer plus reasonable costs and
expenses paid or incurred by Indemnitee up to the date of said notice.

(c)      Any claim by an Indemnitee on account of an Indemnifiable Loss which does not result from a Third
Party Claim (a "Direct Claim") shall be asserted by giving the Indemnifying Party reasonably prompt written
notice thereof, stating the nature of such claim in reasonable detail and indicating the estimated amount, if
practicable, but in any event such notice shall not be given later than twenty (20) calendar days after the
Indemnitee becomes aware of such Direct Claim, and the Indemnifying Party shall have a period of twenty (20)
calendar days within which to respond to such Direct Claim.  If the Indemnifying Party does not respond
within such twenty (20) calendar day period, the Indemnifying Party shall be deemed to have accepted such
claim.  If the Indemnifying Party rejects such claim, the Indemnitee will be free to seek enforcement of its
right to indemnification under this Agreement.

(d)      If the amount of any Indemnifiable Loss, at any time subsequent to the making of an indemnity
payment in respect thereof, is reduced by recovery, settlement or otherwise under or pursuant to any
insurance coverage, or pursuant to any claim, recovery, settlement or payment by, from or against any other
entity, the amount of such reduction, less any costs, expenses or premiums incurred in connection therewith
(together with interest thereon from the date of payment thereof to the date or repayment at the "prime rate"
as published in The Wall Street Journal) shall promptly be repaid by the Indemnitee to the Indemnifying
Party.

(e)      A failure to give timely notice as provided in this Section 8.2 shall not affect the rights or
obligations of any Party hereunder except if, and only to the extent that, as a result of such failure,
the Party which was entitled to receive such notice was actually prejudiced as a result of such failure.

                                                     ARTICLE IX
                                                    TERMINATION

9.1.     TERMINATION. (a)  This Agreement may be terminated at any time prior to the Closing Date by mutual
written consent of Seller and Buyer.

(b)      This Agreement may be terminated by Seller or Buyer, if (i) any Federal or state court of competent
jurisdiction shall have issued an order, judgment or decree permanently restraining, enjoining or otherwise
prohibiting the Closing, and such order, judgment or decree shall have become final and nonappealable or (ii)
any statute, rule, order or regulation shall have been enacted or issued by any Governmental Authority which,
directly or indirectly, prohibits the consummation of the Closing; or (iii) the Closing contemplated hereby
shall have not occurred on or before December 31, 2001 (the "Termination Date"); provided that the right to
terminate this Agreement under this Section 9.1(b)(iii) shall not be available to any Party whose failure to
fulfill any obligation under this Agreement has been the cause of, or resulted in, the failure of the Closing
to occur on or before such date and provided, further, that if on the Termination Date the conditions to the
Closing set forth in Section 7.2(c) or 7.2(d) shall not have been fulfilled but all other conditions to the
Closing shall be fulfilled or shall have been capable of being fulfilled, then the Termination Date shall be
the day which is twenty-four months from the date of this Agreement.

(c)      This Agreement may be terminated by Buyer if any of Seller's Required Regulatory Approvals or
Buyer's Required Regulatory Approvals, the receipt of which is a condition to the obligation of Buyer to
consummate the Closing as set forth in Sections 7.1(c) and 7.1(d), shall have been denied or shall have been
granted but are not in form and substance reasonably satisfactory to Buyer because one of such approvals
contains a condition that would have a material adverse effect on the operations or condition (financial or
otherwise) of the NMP-2 Interests and the NMP-1 Assets, taken as a whole, or a material adverse effect on
the business, assets, operations or condition (financial or otherwise) of Buyer.

(d)      This Agreement may be terminated by Seller with respect to itself if any of its Seller's Required
Regulatory Approvals or Buyer's Regulatory Approvals, the receipt of which are a condition to the obligation
of Seller to consummate the Closing as set forth in Section 7.2(c) and Section 7.2(d), shall have been denied
or shall have been granted but are not in form and substance reasonably satisfactory to Seller, because one
of such approvals contains a condition that would have a material adverse effect on the business, assets,
operations or condition (financial or otherwise) of Seller.

(e)      This Agreement may be terminated by Buyer if there has been a material violation or breach by Seller
of any applicable covenant, representation or warranty contained in this Agreement and such violation or
breach (i) is not adjusted under Section 3.8, (ii) is not cured by the earlier of the Closing Date or the
date thirty (30) days after receipt by Seller (or by Buyer in the case of notice by Seller pursuant to
Section 6.9) of written notice specifying particularly such violation or breach, and (iii) such violation
or breach has not been waived by Buyer.

(f)      This Agreement may be terminated by Seller if there has been a material violation or breach by Buyer
or Parent of any covenant, representation or warranty contained in this Agreement and such violation or
breach is not cured by the earlier of the Closing Date or the date thirty (30) days after receipt by Buyer
or Parent (or by Seller in the case of notice by Buyer or Parent pursuant to Section 6.9) of written notice
specifying particularly such violation or breach, and such violation or breach has not been waived by Seller.

(g)      This Agreement may be terminated by Buyer or Seller in accordance with the provisions of Sections
6.11(b) or (c).

(h)      This Agreement may be terminated by Seller, with respect to itself, if one of the events the
non-occurrence of which is a condition to closing in Section 7.2(o) occurs, which is reasonably likely to
have a material adverse effect on the business, assets, operations or condition (financial or otherwise) of
Seller.

(i)      Buyer recognizes that NMPC shall retain its right prior to Closing to negotiate any successor or
amendment to the IBEW Collective Bargaining Agreement and to make changes in wages and benefits payable to
Non-Union Employees which NMPC deems appropriate to its operations, including the operations of NMP-1.
Buyer agrees that any such successor or amendment to the IBEW Collective Bargaining Agreement shall be
treated as part of the IBEW Collective Bargaining Agreement in accordance with Sections 1.1(71) and 6.10.
This Agreement may be terminated by Buyer (i) within 10 Business Days following NMPC providing to Buyer a
copy of any tentative successor or amendment to the IBEW Collective Bargaining Agreement if the terms thereof
are inconsistent with past practice and would increase materially the aggregate wages, compensation, and
benefits payable to Transferred Employees, except as required by law, or otherwise effect a material adverse
change from the terms of the IBEW Collective Bargaining Agreement as it relates to the Transferred Employees
or the operations of the NMP-1 Assets after the Closing or (ii) if NMPC shall increase the cost of the
aggregate wages, compensation and benefits payable to the Transferred Non-Union Employees in a manner that
would be inconsistent with past practice and would increase materially such cost.  NMPC shall no later than
one day following the execution of any tentative successor or amendment to the IBEW Collective Bargaining
Agreement provide such agreement to Buyer.

9.2.     PROCEDURE AND EFFECT OF NO-DEFAULT TERMINATION. In the event of termination of this Agreement by any
Party pursuant to this Section 9, written notice thereof shall forthwith be given by the terminating Party
to the other Parties, whereupon, if this Agreement is terminated pursuant to Section 9.1 (but only in the
case of termination pursuant to Subsections (e) or (f) where a breach of a representation or warranty by the
non-terminating Party is not willful), the liabilities of the Parties hereunder will terminate, except as
otherwise expressly provided in this Agreement, and thereafter no Party shall have any recourse against any
of the other Parties by reason of this Agreement.

                                                    ARTICLE X
                                             MISCELLANEOUS PROVISIONS

10.1.    AMENDMENT AND MODIFICATION. Subject to applicable law, this Agreement may be amended, modified or
supplemented only by written agreement of Seller and Buyer.

10.2.    WAIVER OF COMPLIANCE; CONSENTS. Except as otherwise provided in this Agreement, any failure of any
of the Parties to comply with any obligation, covenant, agreement or condition herein may be waived by the
Party entitled to the benefits thereof only by a written instrument signed by the Party granting such waiver,
but such waiver of such obligation, covenant, agreement or condition shall not operate as a waiver of, or
estoppel with respect to, any subsequent failure to comply therewith.

10.3.    SURVIVAL OF REPRESENTATIONS, WARRANTIES, COVENANTS AND OBLIGATIONS.

(a)      The representations and warranties given or made by any Party to this Agreement or in the
certificates required by Section 7.1(g) or 7.2(h) shall not survive the Closing and shall be of no further
force or effect, except that (i) all representations and warranties relating to Taxes and Tax Returns shall
survive the Closing for the period of the applicable statutes of limitation plus any extensions or waivers
thereof and (ii) all representations and warranties set forth in Sections 4.21, 4.22 and 5.7 hereof shall
survive the Closing indefinitely.  Each Party shall be entitled to rely upon the representations and
warranties of the other Party or Parties set forth herein, notwithstanding any investigation or audit
conducted before or after the Closing Date or the decision of any Party to complete the Closing.

(b)      The covenants and obligations of the Parties set forth in this Agreement, including without
limitation the indemnification obligations of the Parties under Article VIII hereof, shall survive the
Closing indefinitely, and the Parties shall be entitled to the full performance thereof by the other Parties
hereto without limitation as to time or amount (except as otherwise specifically set forth herein).

given if delivered personally or by facsimile transmission, or mailed by overnight courier or registered or

10.5.    ASSIGNMENT. This Agreement and all of the provisions hereof shall be binding upon and inure to the
benefit of the Parties hereto and their respective successors and permitted assigns, but neither this
Agreement nor any of the rights, interests or obligations hereunder shall be assigned by any Party hereto,
including by operation of law, without the prior written consent of each other Party, such consent not to be
unreasonably withheld, nor is this Agreement intended to confer upon any other Person except the Parties
hereto any rights, interests, obligations or remedies hereunder.  Any assignment in contravention of the
foregoing sentence shall be null and void and without legal effect on the rights and obligations of the
Parties hereunder.  No provision of this Agreement shall create any third party beneficiary rights in any
employee or former employee of Seller (including any beneficiary or dependent thereof) in respect of
continued employment or resumed employment, and no provision of this Agreement shall create any rights in
any such Persons in respect of any benefits that may be provided, directly or indirectly, under any employee
benefit plan or arrangement except as expressly provided for thereunder.  Notwithstanding the foregoing, but
subject to all applicable legal requirements, (i) Buyer or its permitted assignee may grant a security
interest in the rights and interests hereunder to a trustee, lending institution or other party for the
purposes of leasing, financing or refinancing the Purchased Interests, (ii) Buyer or its permitted assignee
may assign, transfer, pledge or otherwise dispose of (absolutely or as security) its rights and interests
hereunder to an Affiliate (an "Assignee Entity") of Buyer at least 68% of the equity securities of which
are owned by Buyer; provided, however, (1) any minority owner of the Assignee Entity shall be that entity
contemplated to become an equity owner of Constellation Energy Group's merchant energy group as set forth in
that certain press release issued by Constellation Energy Group on October 23, 2000, (2) no minority owner
of the Assignee Entity may have any control or management or operational rights or role with respect to the
Assignee Entity , and (3) no such assignment shall relieve or discharge Buyer from any of its obligations
hereunder or shall be made if it would reasonably be expected to prevent or materially impede, interfere with
or delay the transactions contemplated by this Agreement or materially increase the costs of the transactions
contemplated by this Agreement, and (iii) Parent may assign its obligations hereunder to the resulting parent
entity of its unregulated businesses if such businesses are spun-off after the date hereof provided that (A)
(x) such parent entity's long-term unsecured debt credit rating issue by Moody's Investors Service,
Standard & Poor's Corporation or another nationally recognized rating agency is investment grade and (y)
for so long as such parent entity does not have an investment grade rating, then Buyer shall deliver an
irrevocable, standby letter of credit issued by a banking or other financial institution, the long-term
unsecured debt obligations of which is rated investment grade, with a drawing amount equal to the Purchase
Price, in the event such letter of credit is delivered prior to the Closing, or the then outstanding
principal amount, together with any then accrued and unpaid interest on the Note, in the event such letter
of credit is delivered after the Closing, as the case may be, which shall remain in full force and effect
until the entire Purchase Price, and all amounts owed under the Note, are satisfied and paid in full
(or such parent entity reestablishes its investment grade rating); provided, however, after payment in full
of the cash portion of the Purchase Price at Closing by Buyer, Buyer may reduce the drawing amount under
such letter of credit from time to time provided such drawing amount is not less than the then outstanding
principal amount, together with any then accrued and unpaid interest under the Note; and (B) at the time of
such assignment such parent entity makes the same representations and warranties to Seller as those of
Parent contained herein.  Seller agrees, at Buyer's expense, to execute and deliver such documents as may be
reasonably necessary to accomplish any such assignment, transfer, pledge or other disposition of rights
and interests hereunder so long as Seller's rights under this Agreement are not thereby altered, amended,
diminished or otherwise impaired.

10.6.    GOVERNING LAW. Except as provided in Section 3.8, this Agreement shall be governed by and construed
in accordance with the law of the State of New York (without giving effect to conflict of law principles) as
to all matters, including but not limited to matters of validity, construction, effect, performance and
remedies.  THE PARTIES HERETO AGREE THAT VENUE IN ANY AND ALL ACTIONS AND PROCEEDINGS RELATED TO THE SUBJECT
MATTER OF THIS AGREEMENT SHALL BE IN THE STATE AND FEDERAL COURTS FOR ONONDAGA COUNTY, NEW YORK, WHICH COURTS
SHALL HAVE EXCLUSIVE JURISDICTION FOR SUCH PURPOSE (EXCEPT WHERE SUCH ACTION OR PROCEEDING IS REQUIRED BY LAW
TO BE IN OSWEGO COUNTY), AND THE PARTIES HERETO IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF SUCH
COURTS AND IRREVOCABLY WAIVE THE DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF ANY SUCH ACTION OR
PROCEEDING.  SERVICE OF PROCESS MAY BE MADE IN ANY MANNER RECOGNIZED BY SUCH COURTS.  EACH OF THE PARTIES
HERETO IRREVOCABLY WAIVES ITS RIGHT TO A JURY TRIAL WITH RESPECT TO ANY ACTION OR CLAIM ARISING OUT OF ANY
DISPUTE IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

10.7.    COUNTERPARTS. This Agreement may be executed in two or more counterparts, each of which shall be
deemed an original, but all of which together shall constitute one and the same instrument.

10.8.    INTERPRETATION. The articles, section and schedule headings contained in this Agreement are solely
for the purpose of reference, are not part of the agreement of the Parties and shall not in any way affect
the meaning or interpretation of this Agreement.

10.9.    SCHEDULES AND EXHIBITS. Except as otherwise provided in this Agreement, all Exhibits and Schedules
referred to herein are intended to be and hereby are specifically made a part of this Agreement.

10.10.   ENTIRE AGREEMENT. This Agreement, the Confidentiality Agreement and the Ancillary Agreements,
including the Exhibits, Schedules, documents, certificates and instruments referred to herein or therein,
and any other documents executed on the date hereof that specifically reference this Section 10.10, embody

representations, warranties, covenants or undertakings, other than those expressly set forth or referred to
herein or therein.  It is expressly acknowledged and agreed that there are no restrictions, promises,
representations, warranties, covenants or undertakings contained in any material made available to Buyer
pursuant to the terms of the Confidentiality Agreement.

10.11.   BULK SALES LAWS. Buyer acknowledges that, notwithstanding anything in this Agreement to the
contrary, Seller will not comply with the provision of the bulk sales laws of any jurisdiction in connection
with the transactions contemplated by this Agreement.  Buyer hereby waives compliance by Seller with the
provisions of the bulk sales laws of all applicable jurisdictions.

10.12.   PARENTAL SUPPORT. From the date hereof until the effectiveness of the Closing, Parent agrees to
provide to Buyer any and all financial support necessary to permit Buyer to perform its obligations
hereunder.

IN WITNESS WHEREOF, the Parties have caused this Agreement to be signed by their respective duly authorized
officers as of the date first above written.
