                            FIFTH AMENDMENT
                                  OF
                     MASTER RESTRUCTURING AGREEMENT

AMENDMENT entered into on June 2, 1998 (the "Amendment") by and between
NIAGARA MOHAWK POWER CORPORATION, a New York corporation ("NMPC" or the
"Company") and the several independent power producers identified as such on
the signature pages hereto (each, an "IPP" and collectively, the "IPPs").
         
                                 RECITALS

(A)     The Company and the IPPs are parties to that certain Master
Restructuring Agreement entered into on July 9, 1997, as previously amended by
Amendments entered into on March 31, 1998, April 21, 1998, April 30, 1998 and
May 7, 1998 (as so amended, the "MRA").  

(B)     The MRA has been terminated with respect to NorCon Power Partners,
L.P. as of the Conditions Determination Date pursuant to Section 12.2(c) of
the MRA.

(C)     The Company has determined that it will not enter into a CPS Purchase
Agreement with CPS and, accordingly, the Company will make an additional cash
payment pursuant to Section 8.14 of the MRA.

(D)     Pursuant to the MRA, each IPP, other than Encogen and Selkirk (the
"Non-Acquiring IPPs"), that is a party to the MRA on the Consummation Date is
to receive the number of Company Shares allocated to such IPP in the
Allocation.

(E)     Subject to the terms and conditions hereinafter set forth, the Company
and the IPPs have agreed that IPPs may elect to receive, on the Consummation
Date, cash in lieu of all or a portion of the Company Shares allocated to such
IPPs in the Allocation.

(F)     The Parties desire to amend the MRA to reflect certain modifications
to the terms and conditions of the MRA as hereinafter set forth. 
     
     NOW, THEREFORE, in consideration of the foregoing premises and for other
good and valuable consideration, the receipt and adequacy of which is hereby
acknowledged, the parties hereto agree as follows:

1.     Defined Terms.  All capitalized terms used but not otherwise defined
       --------------
herein shall have the meanings ascribed to them in the MRA.

2.     Amendments.
       -----------
          
(A)     The Company hereby confirms that (i) it will not enter into a CPS
Purchase Agreement with CPS as contemplated by Section 8.14(a)(i) of the MRA;
(ii) in lieu thereof it will make the additional cash payment in accordance
with Section 8.14(a)(ii); (iii) WP&Co. has certified to the Company that the
net amount of the value of the Fixed Price Swap Contracts deemed allocated to
NorCon was $33,117,755; and (iv) the additional cash payment to be made by the
Company in accordance with Section 8.14(a)(ii) shall be $296,882,245 (subject
to further reduction in the event the MRA is terminated with respect to any
IPP in accordance with Section 12.2 of the MRA after the date hereof).  The
amount of the increase in the Cash Payment to be made pursuant to Section
8.14(a)(ii) shall be referred to in the MRA as the "Section 8.14 Payment". 
The Company shall, not later than 10:00 a.m. on the Consummation Date, pay to
the Depositary for the benefit and at the direction of all of the IPPs, the
Section 8.14 Payment.  The Section 8.14 Payment shall be paid in the same
manner as the Additional Cash Payment as set forth in Section 3.3(a).  No
Fixed Price Swap Contracts shall be delivered by the Company to the Escrow
Agent and all references to the Fixed Price Swap Contracts in the MRA and in
Exhibit A thereto shall be deleted and the section entitled "Fixed Price Swap
Contracts" on page 6 of Exhibit A and Attachments A-10 and A-11 to Exhibit A
shall be deleted in their entirety.

(B)     In order to reflect the adjustments to the amount of the Cash Payment
and the number of Company Shares resulting from the termination of the MRA
with respect to NorCon and the provisions of Section 3.10 (but not to reflect
any reduction of the Cash Payment pursuant to Section 2.10, the Additional
Cash Payment payable pursuant to Section 3.2 or the Section 8.14 Payment),
Section 3.1 of the MRA is hereby amended by deleting same in its entirety and
substituting the following therefor:

3.1    Allocable Consideration.  The Company shall, not later than 10:00 a.m.
       ------------------------       
on the Consummation Date, pay and/or deliver to the Depositary on behalf of
the IPPs or their respective designees, the following (referred to herein as
the "Allocable Consideration"):

(a)     Three billion four hundred twenty-seven million eight hundred four
thousand dollars ($3,427,804,000) (the "Cash Payment"), subject to adjustment
in accordance with the terms of this Agreement;

(b)     Forty-two million nine hundred forty-five thousand five hundred twelve
(42,945,512) newly-issued, fully-paid and nonassessable shares ("Company
Shares") of Common Stock of the Company, which number of Company Shares shall
be subject to adjustment in accordance with Section 3.5 hereof, and which
number of Company Shares shall be subject to reduction in accordance with
Section 3.10(d) hereof;

(c)     The cash amount to be paid by the Company to Encogen pursuant to the
Encogen Amendment in lieu of Company Shares allocated to Encogen in the
original Allocation; and

(d)     The cash amount to be paid by the Company to each Electing IPP
pursuant to Section 3.10(d) hereof in lieu of all or a portion of the Company
Shares allocated to such Electing IPP in the original Allocation.

(C)     The following new Sections 3.9 and 3.10 are hereby added to the MRA,
which read in their entirety as follows:

3.9     Equity Offering.
        ----------------

(a)     The Company agrees to issue and sell shares of Common Stock ("Shares")
in an underwritten public offering registered with the SEC to be consummated
on or prior to the Consummation Date (the "Equity Offering").  The Equity
Offering shall be underwritten by (i) DLJ, acting as lead manager, (ii)
WP&Co., acting as co-manager and (iii) Merrill Lynch & Co., Salomon Smith
Barney, CIBC Oppenheimer and such other investment banking firms as may be
selected by the Company, acting as co-managers (collectively, the "Equity
Underwriters").  All fees and expenses of the Equity Offering, including
underwriting discounts and commissions, shall be borne solely by the Company.  

(b)     The number of Shares to be included in the Equity Offering shall be
the number of Elected Shares (as hereinafter defined in Section 3.10).

(c)     The Company covenants and agrees that, as of its effective date and as
of the Consummation Date, the prospectus supplement prepared by the Company in
connection with the Equity Offering (the "Equity Prospectus"), shall not and,
as of the time of its filing with the SEC, any document incorporated by
reference therein (as amended to date), or any amendment thereof or supplement
thereto, did not, contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading.  The Company shall provide the IPPs'
Special Counsel with the final draft of the Equity Prospectus and with drafts
of any amendment or supplement thereto, as the case may be, which are provided
to the Equity Underwriters within a reasonable period of time prior to the
filing of same with the SEC, and shall provide the IPPs' Special Counsel with
copies of all correspondence from or with the SEC incidental to the Equity
Prospectus or any such amendment or supplement.

(d)     On or before 9:00 a.m. on the Consummation Date, each IPP (other than
the Non-Acquiring IPPs), and each IPP designee receiving Company Shares
pursuant to Section 3.3(a) or 3.3(b), shall execute and deliver to DLJ, as
representative of the Equity Underwriters, a "lock-up" agreement in the form
annexed as Exhibit 3.9(d) hereto (the "Lock-Up Agreement").

(e)     On the Consummation Date, the Company shall execute and deliver to
each Electing IPP an indemnification agreement in the form annexed as Exhibit
3.9(e) hereto (the "Indemnification Agreement").

3.10     Election to Receive Cash in lieu of Company Shares.
         ---------------------------------------------------

(a)     As used in this Section 3.10:

(i)     "Pricing Date" shall mean the date on which the Equity Underwriters
determine the price at which Shares will be sold in the Equity Offering (which
date is expected to be on or after June 25, 1998, based on a Scheduled
Consummation Date of June 30, 1998).

(ii)     "Pricing Time" shall mean 4:00 p.m. or such other time that the New
York Stock Exchange closes on the Pricing Date.

(iii)    "Closing Price per Share" shall mean the price per share of NMPC's
Common Stock at which the Elected Shares are sold pursuant to the Equity
Offering on the Pricing Date.

(iv)     "Net Price per Share" shall mean the Closing Price per Share minus
the Gross Spread.

(v)      "Gross Spread" shall mean the product of the Closing Price per Share
and the applicable percentage, which includes all underwriting discounts and
commissions, set forth in the separate letter executed simultaneously herewith
by DLJ, as representative of the Equity Underwriters, to the Company and to
WP&Co. on behalf of the IPPs.

(vi)     "Minimum Closing Price per Share" shall mean the minimum Closing
Price per Share that an IPP is willing to accept as the basis for determining
the Net Price per Share with respect to any number of Company Shares elected
by such IPP to be exchanged for cash, as such IPP may advise WP&Co. from time
to time up to one hour prior to the Pricing Time.


(b)     Subject to the provisions of this Section 3.10, each IPP shall have
the right to elect to receive on the Consummation Date, in lieu of all or any
portion of the Company Shares allocated to such IPP in the Allocation, cash
equal to the Net Price per Share multiplied by the number of such IPP's
Elected Shares.  Such election shall be made by notice to WP&Co. given not
later than one hour prior to the Pricing Time.  Each IPP has authorized WP&Co.
to notify the Company and DLJ, as representative of the Equity Underwriters,
of the aggregate number of Company Shares that IPPs desire to exchange for
cash at each Minimum Closing Price per Share that such IPPs are willing to
accept in lieu of such number of Company Shares.  Any IPP that so elects to
receive cash in lieu of Company Shares is referred to herein as an "Electing
IPP".  

(c)     The aggregate number of Company Shares that Electing IPPs elect to
exchange for cash in accordance with Section 3.10(b) are referred to herein as
"Elected Shares".  However, if the number of Elected Shares is in excess of
the Minimum Offering Size (as hereinafter defined) and DLJ, as representative
of the Equity Underwriters, advises WP&Co. on behalf of the Electing IPPs that
marketing factors require a limitation on the number of Shares to be
underwritten in the Equity Offering, then the number of Elected Shares shall
be reduced to the amount acceptable to DLJ, as representative of the Equity
Underwriters, provided that the number of Elected Shares shall not be reduced
as a result of marketing factors to less than 15,674,149 Company Shares.  Such
number of Company Shares is referred to herein as the "Minimum Offering Size." 
The Company understands, however, that the number of Elected Shares and the
Minimum Offering Size may be reduced by an Electing IPP, if the Closing Price
per Share is less than such IPP's Minimum Closing Price per Share.

(d)     The Company shall, not later then 10:00 a.m. on the Consummation Date,
pay to the Depositary on behalf of the IPPs or their respective designees, the
Net Price per Share multiplied by the number of Elected Shares.  Such amount
shall be paid in the same manner as the Cash Payment as set forth in Section
3.3(a).  The number of Company Shares to be delivered by the Company pursuant
to Section 3.1(b) shall be reduced by the number of Elected Shares.

(e)     No IPP (or corresponding entity or entities of such IPP listed on
Schedule 3.7) that is required to enter into a Shareholders' Agreement
pursuant to Section 3.7 shall be required to do so if, as a result of an
election by such IPP to exchange any Company Shares allocated to it for cash
pursuant to this Section 3.10 (and/or as a result of any reallocation or
redesignation referred to in the first parenthetical clause of Section 3.7),
such IPP, together with its Affiliate IPPs, members of its Sponsor Group and
its Excluded Affiliates (as said latter two terms are defined in the
Shareholders' Agreement), shall acquire on the Consummation Date Company
Shares representing less than two percent (2%) of the outstanding Common Stock
of the Company.  The IPPs shall cause WP&Co. to certify in writing to the
Company on the day following the Pricing Date the name of each IPP that is not
required to enter into a Shareholders' Agreement as a result of this Section
3.10(e).

(f)     The IPPs hereby authorize and instruct WP&Co. (i) to report to the
Company and DLJ, as representative of the Equity Underwriters, the aggregate
number of Elected Shares at each Minimum Closing Price per Share, and (ii) to
notify the Depositary, (x) in conjunction with the Company, of the aggregate
number of Elected Shares and of the amount of the aggregate additional cash
payment to be made by the Company in lieu of such number of Elected Shares
pursuant to this Section 3.10 and (y) in conjunction with each Electing IPP,
of the number of Elected Shares by such IPP and the additional cash payment to
be received by such IPP in lieu of such number of Elected Shares.  The Company
agrees to accept WP&Co.'s directions and instructions given pursuant to this
Section 3.10 on behalf of the IPPs.

(D)     The term "Specified Restructuring Documents", as used in Exhibits 8.3C
and 9.3C of the MRA, shall be amended to include, as applicable (i.e., if the
Company or an IPP is a party to such document), the Termination Agreements,
the Lock-Up Agreement, and the Indemnification Agreement.

(E)     (1)     The provisions of Section 3.6 of the MRA are modified to the
extent set forth in this paragraph (E).  The Company agrees to file with the
SEC the Shelf Registration Statement not later than June 3, 1998 and to use
its Reasonable Best Efforts, promptly and diligently, to cause the Shelf
Registration Statement to be declared effective by the SEC on or prior to the
Consummation Date or, if not feasible, as promptly after the Consummation Date
as is feasible.  The Company shall permit the IPPs' Special Counsel to review
and comment on the final draft of the Shelf Registration Statement at least
three (3) business hours prior to the filing of same with the SEC, and shall
not file same in a form to which such counsel reasonably objects within said
three business hour period.

(2)     The conditions set forth in Section 8.12(a) and (b) of the MRA shall
be modified to provide that if such conditions have not been satisfied on or
before the Consummation Date, then such conditions shall be waived so long as,
with respect to any IPP that is acquiring Company Shares as of the
Consummation Date, (i) the Shelf Registration Statement shall have been filed
with the SEC and shall have been amended or supplemented as necessary to
reflect any comments of the SEC incidental to the Shelf Registration Statement
received more than two (2) business days prior to the Consummation Date or as
may be required for the Shelf Registration Statement not to contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading and
(ii) the IPP, after consultation with WP&Co. and the IPPs' Special Counsel,
has no reason to believe that it is likely that the conditions set forth in
Section 8.12(a) and (b) will not be satisfied within fifteen (15) days after
the Consummation Date.  If the conditions set forth in Section 8.12(a) and (b)
have not been satisfied on or before the Consummation Date, the Parties will
execute the Registration Rights Agreement in accordance with Section 3.6 of
the MRA on the Consummation Date, but will deposit each counterpart of the
Registration Rights Agreement with the Escrow Agent, to be held in escrow
pursuant to the Escrow Agreement until the conditions set forth in Section
8.12(a) and (b) have been satisfied.

(3)     If, following fifteen (15) days after the Consummation Date, the
conditions set forth in Section 8.12(a) and (b) have not been satisfied, and
the IPP has the right to sell or transfer Company Shares under the provisions
of the Lock-Up Agreement, or following the expiration of the Lock-Up
Agreement, then the IPP may elect to give a notice to the Company stating that
such IPP desires to sell all or any portion of such IPP's Company Shares,
which notice shall specify the number of such Company Shares desired to be
sold (a "Sale Notice").  If an IPP shall give a Sale Notice, then the Company
shall, at the IPP's option, (x) pay to such IPP, following the sale of such
Company Shares pursuant to the Shelf Registration Statement (which may occur
only after the Shelf Registration Statement has been declared effective) the
excess, if any, of the Sale Notice Market Price (as defined below) over the
Effective Date Market Price (as defined below), multiplied by the number of
Company Shares sold, together with interest thereon at the rate of eight
percent (8%) per annum from the date the Sale Notice is given to the date of
payment, or (y) pay to such IPP, following the sale of such Company Shares to
an unaffiliated third party (which shall not be another IPP, unless such sale
is on an arms' length basis) other than pursuant to the Shelf Registration
Statement, the excess, if any, of the Sale Notice Market Price over the gross
price per share paid, for such Company Shares, multiplied by the number of
Company Shares sold; provided that with respect to this clause (y) the amount
of such excess shall not be greater than the amount that such IPP's investment
banker certifies to the Company as an appropriate discount applicable to a
sale of the number of Company Shares sold as a result of such Company Shares
being unregistered.  If any IPP shall sell Company Shares prior to the date
the Shelf Registration Statement is declared effective and notifies the
Company of the identity of the buyer in writing, the Company shall amend the
Shelf Registration Statement to include the buyer as a selling shareholder
thereunder.  As used herein, the "Sale Notice Market Price" shall mean the
closing price per share of the Company's Common Stock as published in the New
York Stock Exchange Composite Transactions Section of The Wall Street Journal
for the last trading day preceding the date the Sale Notice is given; and the
"Effective Date Market Price" shall mean the closing price per share of the
Company's Common Stock as published in the New York Stock Exchange Composite
Transactions Section of The Wall Street Journal for the first trading day
after the Shelf Registration Statement is declared effective. 

(F)     Section 6.1 of the MRA is amended by deleting the last sentence
thereof in its entirety and substituting the following new sentence therefor:
The Company agrees that (x) the aggregate principal amount of the Debt
Securities issued in connection with the Public Offering shall not exceed
three billion four hundred fifty million ($3,450,000,000) dollars and (y) the
Debt Securities shall be general unsecured obligations of the Company.

(G)     The fourth sentence of Section 3.3(a) of the MRA is amended by
deleting the words "not less than eight (8) Business Days prior to the
Consummation Date" and substituting therefor the words "not later than the
next Business Day after the Pricing Date".

3.     No Other Amendment. Except as expressly set forth in this Amendment,
       -------------------
none of the rights or obligations of the parties hereto pursuant to the MRA
shall be amended, modified, waived, terminated or otherwise affected by this
Amendment in any manner whatsoever.  Without limiting the generality of the
foregoing, the parties hereto agree that except as expressly set forth in the
Encogen Amendment (with respect to Encogen only), any prior amendment of the
MRA, or herein, the Allocation with respect to each IPP shall remain
unchanged, and nothing contained herein shall increase or reduce the Allocable
Consideration payable to any IPP, nor in any way affect the Additional Cash
Payment or the terms of any Termination Agreements, Amended PPAs or Restated
Contracts (including any amendments thereto or agreements to amend such
Restated Contracts executed prior to the date hereof).

4.     Ratification.  Each party hereto agrees that (i) the MRA is in full
       -------------
force and effect and (ii) to the best knowledge of such party, there is no
current breach or default on the part of any other party or any other event or
condition which, upon notice, the passage of time, or both, would constitute
such a breach or default.

5.     Counterparts; Facsimile.  This Amendment 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.  This Amendment may be
delivered with only a facsimile signature, with the same force and effect as
if an original signature had been delivered.

6.     Entire Agreement.  This Amendment constitutes the entire agreement
       -----------------
between the parties hereto with respect to the subject matter hereof, and
supersedes all prior agreements and understandings, written or oral, between
the parties hereto with respect thereto. 

IN WITNESS WHEREOF, the parties have duly executed this Fifth Amendment of
Master Restructuring Agreement, effective as of the day and year first above
written.

                NIAGARA MOHAWK MARKS NEW ERA AS SHAREHOLDERS APPROVE
                 STOCK ISSUANCE FOR MASTER RESTRUCTURING AGREEMENT
        Vote Clears Way For Closing Of IPP Deal, Lower Electricity Prices
     
     BUFFALO, June 30   Capping a turnaround effort that began nearly three
years ago, shareholders of Niagara Mohawk Power Corp. (NYSE: NMK) yesterday
approved issuance of up to 43 million shares of common stock in connection
with the company's Master Restructuring Agreement (MRA).  The vote came at the
company's 49th annual shareholders' meeting in Buffalo.

     The approval marks the final step necessary to consummate the landmark
agreement that calls for Niagara Mohawk to terminate, restate or amend 27
government-mandated Independent Power Producer (IPP) contracts that represent
approximately 75 percent of the company's above-market prices. In exchange,
the IPPs will receive approximately $3.6 billion in cash, approximately 20.5
million shares of Niagara Mohawk common stock and proceeds from the sale of
22.4 million shares of Niagara Mohawk common stock. Shareholder approval of
the stock portion of the transaction will allow the parties to consummate the
MRA by today's closing date.  

     "This shareholder action marks the beginning of a new era for Niagara
Mohawk," said William E. Davis, company chairman and chief executive officer. 
"We now can resolve our IPP problem, the most burdensome and intractable
problem this company has ever faced."

     The MRA will reduce Niagara Mohawk's annual IPP payments by more than
$500 million.  The improved cash flow will allow the company to reduce
electricity prices for all customers and pay off the debt required to finance
the MRA over a six-to-seven-year period, thus putting an end to the bulk of
its IPP cost burden.
 
     "The next 18 months will be another critically important time for Niagara
Mohawk," Davis said.  "After consummating the MRA, we will implement the
PowerChoice price reductions, complete the auction of our fossil and hydro
generation assets, restructure the company and provide retail choice to all
customers by the end of 1999," he said.
 
     "You can truly feel the momentum building.  We have received bond-rating
upgrades from Standard & Poor's and Moody's in the past four months.  Our
common stock is now trading in the $14 range, compared with $8 or so a year
ago.  Next, we will close on one of the largest utility financings ever and
put behind us a problem some thought could not be solved short of bankruptcy."

                         Additional Shareholder Action

     Also at the meeting, shareholders voted to amend the company's
Certificate of Incorporation to increase to 250 million shares the amount of
common stock Niagara Mohawk is authorized to issue.  In addition, shareholders
approved the formation of a holding company structure. Under the PowerChoice
agreement, the company has approximately one year within which it may adopt
such a structure. The implementation of a holding company will not occur until
the company receives all necessary regulatory approvals.


     In other shareholder action, five directors were elected to three-year
terms.  They are Salvatore H. Alfiero, chairman and chief executive officer of
Mark IV Industries; Albert J. Budney Jr., president and chief operating
officer of Niagara Mohawk; Dr. Bonnie Guiton Hill, president and chief
executive officer of The Times Mirror Foundation and vice president of The
Times Mirror Co.; Clark A. Johnson, chairman and chief executive officer of
Pier 1 Imports; and Henry A. Panasci Jr., chairman of Cygnus Management Group. 
Alfiero and Johnson are new to the Niagara Mohawk board. Yesterday also marked
the last annual meeting for Edmund M. Davis, who is retiring from Niagara
Mohawk's Board of Directors after 28 years of service.  As a result of these
activities, Niagara Mohawk will have 14 board members.

     In addition, a shareholder proposal seeking the company's endorsement of
the CERES Principles was voted down.  A second proposal relating to executive
compensation was not presented at the meeting.
  
     Niagara Mohawk is an investor-owned energy services company that provides
electricity to more than 1.5 million customers across 24,000 squares miles of
Upstate New York.  The company also delivers natural gas to more than 500,000
customers over 4,500 square miles of eastern, central and northern New York.

            NIAGARA MOHAWK, INDEPENDENT POWER PRODUCERS CONSUMMATE MASTER      
                          RESTRUCTURING AGREEMENT

                Company to Record Non-Cash Charge Associated with MRA; 
         Will Move Ahead with PowerChoice Price Reductions, Retail Access
     
     
     SYRACUSE, June 30 -- Niagara Mohawk Power Corp. (NYSE:NMK) today
consummated its landmark Master Restructuring Agreement with 14 Independent
Power Producers (IPPs), paving the way for electricity price reductions for
the company's 1.5 million customers and a brighter financial outlook for
shareholders.

     The MRA allows Niagara Mohawk to terminate, restate or amend 27
government-mandated IPP contracts that represent approximately 75 percent of
the company's above-market prices. In exchange, the IPPs received
approximately $3.6 billion in cash, approximately 20.5 million shares of
Niagara Mohawk common stock and proceeds from the sale of 22.4 million shares
of Niagara Mohawk common stock.  

     "This day marks a very important milestone in the financial turnaround of
Niagara Mohawk," said William E. Davis, company chairman and chief executive
officer. "We have successfully resolved the bulk of our IPP problem, the most
burdensome and intractable problem this company has ever faced." 

     The MRA will reduce Niagara Mohawk's IPP payments by more than  $500
million annually.  The improved cash flow will allow the company to reduce
electricity prices for all customers and pay off the debt required to finance
the MRA over a six-to-seven-year period.  Without the MRA, Niagara Mohawk's
IPP payments, which currently exceed $1 billion annually, were projected to
grow 22 percent by 1999 and increase at a faster-than-inflation rate through
2020.   
     
     Davis noted that the next 18 months will be another critically important
time for Niagara Mohawk. During that period, the company will implement the
PowerChoice price reductions, complete the auction of its fossil and hydro
generation assets, form a holding company and provide retail choice to all
customers by the end of 1999.

     With the closing of the MRA, the company will record a non-cash charge to
earnings of $263.2 million in the second quarter.  The charge was required
because the Public Service Commission order approving PowerChoice limited the
cost of the MRA that can be recovered from customers by valuing the common
stock issued in the transaction at $8 per share.

electricity to more than 1.5 million customers across 24,000 squares miles of
Upstate New York.  The company also delivers natural gas to more than 500,000
customers over 4,500 square miles of eastern, central and northern New York.
