                 Section 2.  THE REVOLVING CREDIT FACILITY.

            Section 2.1.  Commitment to Lend.


            Subject to the terms and conditions set forth in this
Credit Agreement, each of the Banks severally agrees to lend
to the Borrower and the Borrower may borrow, repay, and
reborrow from time to time from the Closing Date up to but
not including the Revolving Credit Loan Maturity Date upon
notice by the Borrower to the Administrative Agent given in
accordance with Section 2.6, such sums as are requested by
the Borrower up to a maximum aggregate amount outstanding
(after giving effect to all amounts requested) at any one
time equal to such Bank's Commitment minus such Bank's
Commitment Percentage of the sum of the Maximum Drawing
Amount and all Unpaid Reimbursement Obligations, provided
that the sum of the outstanding amount of the Revolving
Credit Loans (after giving effect to all amounts requested)
plus the Maximum Drawing Amount and all Unpaid Reimbursement
Obligations shall not at any time exceed the Total
Commitment.  The Revolving Credit Loans shall be made pro
rata in accordance with each Bank's Commitment Percentage. 
Each request for a Revolving Credit Loan hereunder shall
constitute a representation and warranty by the Borrower
that the conditions set forth in Section 12 and Section 13,
in the case of the initial Revolving Credit Loans to be made
on the Closing Date, and Section 13, in the case of all
other Revolving Credit Loans, have been satisfied on the
date of such request.

            Section 2.2.  Commitment Fee.

            The Borrower agrees to pay to the Administrative Agent
for the accounts of the Banks in accordance with their
respective Commitment Percentages a commitment fee
calculated at the Commitment Fee Rate on the average daily
amount during each calendar quarter or portion thereof from
the date hereof to the Revolving Credit Loan Maturity Date
by which the Total Commitment minus the sum of the Maximum
Drawing Amount and all Unpaid Reimbursement Obligations
exceeds the outstanding amount of Revolving Credit Loans
during such calendar quarter.  The commitment fee shall be
payable quarterly in arrears on the first day of each
calendar quarter for the immediately preceding calendar
quarter commencing on the first such date following the date
hereof, with a final payment on the Revolving Credit
Maturity Date or any earlier date on which the Commitments
shall terminate.

            Section 2.3.  Reduction of Total Commitment.

          The Borrower shall have the right at any time and from
time to time upon five (5) Business Days prior written
notice to the Administrative Agent to reduce by $5,000,000
or in integral multiples of $1,000,000 in excess of
$5,000,000 or terminate entirely the Total Commitment,
whereupon the Commitments of the Banks shall be reduced pro
rata in accordance with their respective Commitment
Percentages of the amount specified in such notice or, as
the case may be, terminated.  Promptly after receiving any
notice of the Borrower delivered pursuant to this Section
2.3, the Administrative Agent will notify the Banks of the
substance thereof.  Upon the effective date of any such
reduction or termination, the Borrower shall pay to the
Administrative Agent for the respective accounts of the
Banks the full amount of any commitment fee then accrued on
the amount of the reduction.  No reduction or termination of
the Commitments may be reinstated.

            Section 2.4.  The Revolving Credit Notes.

                 (a)  The Revolving Credit Loans shall be evidenced
            by separate amended and restated promissory notes of
            the Borrower in substantially the form of Exhibit A
            hereto (each a "Revolving Credit Note"), dated as of
            the Closing Date or the effective date of any future
            assignment made pursuant to Section 19 hereof and
            completed with appropriate insertions.  One Revolving
            Credit Note shall be payable to the order of each Bank
            in a principal amount equal to such Bank's Commitment
            and representing the obligation of the Borrower to pay
            to such Bank such principal amount or, if less, the
            outstanding amount of all Revolving Credit Loans made
            by such Bank, plus interest accrued thereon, as set
            forth below.  The Borrower irrevocably authorizes each
            Bank to make or cause to be made, at or about the time
            of the Drawdown Date of any Revolving Credit Loan or at
            the time of receipt of any payment of principal on such
            Bank's Revolving Credit Note, an appropriate notation
            on such Bank's Revolving Credit Note Record reflecting
            the making of such Revolving Credit Loan or (as the
            case may be) the receipt of such payment.  The
            outstanding amount of the Revolving Credit Loans set
            forth on such Bank's Revolving Credit Note Record
            shall, absent manifest error, be prima facie evidence
            of the principal amount thereof owing and unpaid to
            such Bank, but the failure to record, or any error in
            so recording, any such amount on such Bank's Revolving
            Credit Note Record shall not limit or otherwise affect
            the obligations of the Borrower hereunder or under any
            Revolving Credit Note to make payments of principal of
            or interest on any Revolving Credit Note when due.

                 (b)  Upon receipt of an affidavit of an officer of
            any Bank as to the loss, theft, destruction or
            mutilation of such Bank s Revolving Credit Note, and,
            in the case of any such loss, theft, destruction or
            mutilation, upon surrender and cancellation of such
            Revolving Credit Note, the Borrower will issue, in lieu
            thereof, a replacement Revolving Credit Note for such
            Bank in the same principal amount thereof and otherwise
            of like tenor.

Section 2.5.  Interest on Revolving Credit Loans.

Except as otherwise provided in Section 6.10,

                 (a)  Each Base Rate Loan shall bear interest for
            the period commencing with the Drawdown Date thereof
            and ending on the last day of the Interest Period with
            respect thereto at the Base Rate plus the Applicable
            Margin.

                 (b)  Each LIBOR Rate Loan shall bear interest for
            the period commencing with the Drawdown Date thereof
            and ending on the last day of the Interest Period with
            respect thereto at the LIBOR Rate plus the Applicable
            Margin determined for such Interest Period.

                 (c)  The Borrower promises to pay interest on each
            Revolving Credit Loan in arrears on each Interest
            Payment Date with respect thereto.

            Section 2.6.  Requests for Revolving Credit Loans.  The
Borrower shall give to the Administrative Agent written
notice in the form of Exhibit B hereto (or telephonic notice
confirmed in a writing in the form of Exhibit B hereto) of
each Revolving Credit Loan requested hereunder (a "Loan
Request") no later than (i) 10:00 a.m.(Boston time) on the
Business Day of the proposed Drawdown Date of any Base Rate
Loan and (ii) 12:00 noon (Boston time) three (3) LIBOR
Business Days prior to the proposed Drawdown Date of any
LIBOR Rate Loan.  Each such notice shall specify (A) the
principal amount of the Revolving Credit Loan requested, (B)
the proposed Drawdown Date of such Revolving Credit Loan,
(C) in the case of LIBOR Rate Loans the Interest Period for
such Revolving Credit Loan and (D) the Type of such
Revolving Credit Loan.  Promptly upon receipt of any such
notice, the Administrative Agent shall notify each of the
Banks thereof. Each Loan Request shall be irrevocable and
binding on the Borrower and shall obligate the Borrower to
accept the Revolving Credit Loan requested from the Banks on
the proposed Drawdown Date.  Each Loan Request shall be in a
minimum aggregate amount of $500,000 or an integral multiple
thereof.

            Section   2.7.  Conversion Options.

                 Section 2.7.1.  Conversion to Different Type of
            Revolving Credit Loan.

            The Borrower may elect from time to time to convert any
outstanding Revolving Credit Loan to a Revolving Credit Loan
of another Type, provided that (i) with respect to any such
conversion of a Revolving Credit Loan to a Base Rate Loan,
the Borrower shall give the Administrative Agent at least
two (2) Business Days prior written notice of such election;
(ii) with respect to any such conversion of a Base Rate Loan
to a LIBOR Rate Loan, the Borrower shall give the
Administrative Agent at least three (3) LIBOR Business Days
prior written notice of such election; (iii) with respect to
any such conversion of a LIBOR Rate Loan into a Revolving
Credit Loan of another Type, such conversion shall only be
made on the last day of the Interest Period with respect
thereto and (iv) no Loan may be converted into a LIBOR Rate
Loan when any Default or Event of Default has occurred and
is continuing or if such conversion is not permitted by
Section 2.7.3.  On the date on which such conversion is
being made each Bank shall take such action as is necessary
to transfer its Commitment Percentage of such Revolving
Credit Loans to its Domestic Lending Office or its LIBOR
Lending Office, as the case may be.  All or any part of
outstanding Revolving Credit Loans of any Type may be
converted into a Revolving Credit Loan of another Type as
provided herein, provided that any partial conversion shall
be in an aggregate principal amount of $500,000 or an
integral multiple thereof.  Each Conversion Request relating
to the conversion of a Revolving Credit Loan to a LIBOR Rate
Loan shall be irrevocable by the Borrower.

                 Section 2.7.2.  Continuation of Type of Revolving
            Credit Loan.

Any Revolving Credit Loan of any Type may be continued as a
Revolving Credit Loan of the same Type upon the expiration
of an Interest Period with respect thereto by compliance by
the Borrower with the notice provisions contained in Section
2.7.1; provided that no LIBOR Rate Loan may be continued as
such when any Event of Default has occurred and is
continuing, but shall be automatically converted to a Base
Rate Loan on the last day of the first Interest Period
relating thereto ending during the continuance of any Event
of Default of which officers of the Administrative Agent
active upon the Borrower's account have actual knowledge. 
In the event that the Borrower fails to provide any such
notice with respect to the continuation of any LIBOR Rate
Loan as such, then such LIBOR Rate Loan shall be
automatically converted to a Base Rate Loan on the last day
of such Interest Period.  The Administrative Agent shall
notify the Banks promptly when any such automatic conversion
contemplated by this Section 2.7 is scheduled to occur.

                 Section 2.7.3.  LIBOR Rate Loans.

                 Any conversion to or from LIBOR Rate Loans shall
            be in such amounts and be made pursuant to such
            elections so that, after giving effect thereto, the
            aggregate principal amount of all LIBOR Rate Loans
            having the same Interest Period shall not be less than
            $500,000 or an integral multiple thereof.

            Section 2.8.  Funds for Revolving Credit Loan.

                 Section 2.8.1.  Funding Procedures.

                 Not later than 11:00 a.m. (Boston time) on the
            proposed Drawdown Date of any Revolving Credit Loans,
            each of the Banks will make available to the
            Administrative Agent, at the Administrative Agent's
            Head Office, in immediately available funds, the amount
            of such Bank's Commitment Percentage of the amount of
            the requested Revolving Credit Loans.  Upon receipt
            from each Bank of such amount, and upon receipt of the
            documents required by Section Section 12 and 13 and the
            satisfaction of the other conditions set forth therein,
            to the extent applicable, the Administrative Agent will
            make available to the Borrower the aggregate amount of
            such Revolving Credit Loans made available to the
            Administrative Agent by the Banks.  The failure or
            refusal of any Bank to make available to the
            Administrative Agent at the aforesaid time and place on
            any Drawdown Date the amount of its Commitment
            Percentage of the requested Revolving Credit Loans
            shall not relieve any other Bank from its several
            obligation hereunder to make available to the
            Administrative Agent the amount of such other Bank's
            Commitment Percentage of any requested Revolving Credit
            Loans.

                 Section 2.8.2.  Advances by Administrative
            Agent.

                 The Administrative Agent may, unless notified to
            the contrary by any Bank prior to a Drawdown Date,
            assume that such Bank has made available to the
            Administrative Agent on such Drawdown Date the amount
            of such Bank's Commitment Percentage of the Revolving
            Credit Loans to be made on such Drawdown Date, and the
            Administrative Agent may (but it shall not be required
            to), in reliance upon such assumption, make available
            to the Borrower a corresponding amount.  If any Bank
            makes available to the Administrative Agent such amount
            on a date after such Drawdown Date, such Bank shall pay
            to the Administrative Agent on demand an amount equal
            to the product of (i) the average computed for the
            period referred to in clause (iii) below, of the
            weighted average interest rate paid by the
            Administrative Agent for federal funds acquired by the
            Administrative Agent during each day included in such
            period, times (ii) the amount of such Bank's Commitment
            Percentage of such Revolving Credit Loans, times (iii)
            a fraction, the numerator of which is the number of
            days that elapse from and including such Drawdown Date
            to the date on which the amount of such Bank's
            Commitment Percentage of such Revolving Credit Loans
            shall become immediately available to the
            Administrative Agent, and the denominator of which is
            365.  A statement of the Administrative Agent submitted
            to such Bank with respect to any amounts owing under
            this paragraph shall be prima facie evidence of the
            amount due and owing to the Administrative Agent by
            such Bank.  If the amount of such Bank's Commitment
            Percentage of such Revolving Credit Loans is not made
            available to the Administrative Agent by such Bank
            within three (3) Business Days following such Drawdown
            Date, the Administrative Agent shall be entitled to
            recover such amount from the Borrower on demand, with
            interest thereon at the rate per annum applicable to
            the Revolving Credit Loans made on such Drawdown Date.

            Section 2.9.  Settlements.

                 Section 2.9.1.  General.

                 On each Settlement Date, the Administrative Agent
            shall, not later than 11:00 a.m. (Boston time), give
            telephonic or facsimile notice (i) to the Banks and the
            Borrower of the respective outstanding amount of
            Revolving Credit Loans made by the Administrative Agent
            on behalf of the Banks from the immediately preceding
            Settlement Date through the close of business on the
            prior day and the amount of any LIBOR Rate Loans to be
            made (following the giving of notice pursuant to
            Section 2.6.1(ii)) on such date pursuant to a Loan
            Request and (ii) to the Banks of the amount (a
            "Settlement Amount") that each Bank (a "Settling Bank")
            shall pay to effect a Settlement of any Revolving
            Credit Loan.  A statement of the Administrative Agent
            submitted to the Banks and the Borrower or to the Banks
            with respect to any amounts owing under this Section
            2.9 shall be prima facie evidence of the amount due and
            owing.  Each Settling Bank shall, not later than 3:00
            p.m. (Boston time) on such Settlement Date, effect a
            wire transfer of immediately available funds to the
            Administrative Agent in the amount of the Settlement
            Amount for such Settling Bank.  All funds advanced by
            any Bank as a Settling Bank pursuant to this Section
            2.9 shall for all purposes be treated as a Revolving
            Credit Loan made by such Settling Bank to the Borrower
            and all funds received by any Bank pursuant to this
            Section 2.9 shall for all purposes be treated as
            repayment of amounts owed with respect to Revolving
            Credit Loans made by such Bank.  In the event that any
            bankruptcy, reorganization, liquidation, receivership
            or similar cases or proceedings in which the Borrower
            is a debtor prevent a Settling Bank from making any
            Revolving Credit Loan to effect a Settlement as
            contemplated hereby, such Settling Bank will make such
            dispositions and arrangements with the other Banks with
            respect to such Revolving Credit Loans, either by way
            of purchase of participations, distribution, pro tanto
            assignment of claims, subrogation or otherwise as shall
            result in each Bank's share of the outstanding
            Revolving Credit Loans being equal, as nearly as may
            be, to such Bank's Commitment Percentage of the
            outstanding amount of the Revolving Credit Loans.

                 Section 2.9.2.  Failure to Make Funds Available.  

                 The Administrative Agent may, unless notified to
            the contrary by any Settling Bank prior to a Settlement
            Date, assume that such Settling Bank has made or will
            make available to the Administrative Agent on such
            Settlement Date the amount of such Settling Bank's
            Settlement Amount, and the Administrative Agent may
            (but it shall not be required to), in reliance upon
            such assumption, make available to the Borrower a
            corresponding amount.  If any Settling Bank makes
            available to the Administrative Agent such amount on a
            date after such Settlement Date, such Settling Bank
            shall pay to the Administrative Agent on demand an
            amount equal to the product of (i) the average computed
            for the period referred to in clause (iii) below, of
            the weighted average interest rate paid by the
            Administrative Agent for federal funds acquired by the
            Administrative Agent during each day included in such
            period, times (ii) the amount of such Settlement
            Amount, times (iii) a fraction, the numerator of which
            is the number of days that elapse from and including
            such Settlement Date to the date on which the amount of
            such Settlement Amount shall become immediately
            available to the Administrative Agent, and the
            denominator of which is 360.  A statement of the
            Administrative Agent submitted to such Settling Bank
            with respect to any amounts owing under this Section
            2.9.2 shall be prima facie evidence of the amount due
            and owing to the Administrative Agent by such Settling
            Bank.  If such Settling Bank's Settlement Amount is not
            made available to the Administrative Agent by such
            Settling Bank within three (3) Business Days following
            such Settlement Date, the Administrative Agent shall be
            entitled to recover such amount from the Borrower on
            demand, with interest thereon at the rate per annum
            applicable to the Revolving Credit Loans as of such
            Settlement Date.

                 Section 2.9.3.  No Effect on Other Banks.

                 The failure or refusal of any Settling Bank to
            make available to the Administrative Agent at the
            aforesaid time and place on any Settlement Date the
            amount of such Settling Bank's Settlement Amount shall
            not (i) relieve any other Settling Bank from its
            several obligations hereunder to make available to the
            Administrative Agent the amount of such other Settling
            Bank's Settlement Amount or (ii) impose upon any Bank,
            other than the Settling Bank so failing or refusing,
            any liability with respect to such failure or refusal
            or otherwise increase the Commitment of such other
            Bank.

                 Section 3.  REPAYMENT OF THE REVOLVING CREDIT LOANS.

            Section 3.1.  Maturity.

            The Borrower promises to pay on the Revolving Credit
Loan Maturity Date, and there shall become absolutely due
and payable on the Revolving Credit Loan Maturity Date, all
of the Revolving Credit Loans outstanding on such date,
together with any and all accrued and unpaid interest
thereon.

          Section 3.2.  Mandatory Repayments of Revolving Credit Loans.

If at any time the sum of the outstanding amount of the
Revolving Credit Loans, the Maximum Drawing Amount and all
Unpaid Reimbursement Obligations exceeds the Total
Commitment, then the Borrower shall immediately pay the
amount of such excess to the Administrative Agent for the
respective accounts of the Banks for application:  first, to
any Unpaid Reimbursement Obligations; second, to the
Revolving Credit Loans; and third, to provide to the
Administrative Agent cash collateral for Reimbursement
Obligations as contemplated by Section 5.2(b) and (c).  Each
payment of any Unpaid Reimbursement Obligations or
prepayment of Revolving Credit Loans shall be allocated
among the Banks, in proportion, as nearly as practicable, to
each Reimbursement Obligation or (as the case may be) the
respective unpaid principal amount of each Bank's Revolving
Credit Note, with adjustments to the extent practicable to
equalize any prior payments or repayments not exactly in
proportion.

            Section 3.3.  Optional Repayments of Revolving Credit
Loans.


The Borrower shall have the right, at its election, to repay
the outstanding amount of the Revolving Credit Loans, as a
whole or in part, without premium or penalty (but subject to
Section 6.9), provided that the Borrower shall give the
Administrative Agent, no later than 10:00 a.m., Boston time,
at least five (5) Business Days prior written notice of any
proposed prepayment pursuant to this Section 3.3 of Base
Rate Loans, and five (5) LIBOR Business Days notice of any
proposed prepayment pursuant to this Section 3.3 of LIBOR
Rate Loans, in each case specifying the proposed date of
prepayment of Revolving Credit Loans and the principal
amount to be prepaid.  Each such partial prepayment of the
Revolving Credit Loans shall be in an integral multiple of
$500,000, shall be accompanied by the payment of accrued
interest on the principal prepaid to the date of prepayment
and shall be applied, in the absence of instruction by the
Borrower, first to the principal of Base Rate Loans and then
to the principal of LIBOR Rate Loans, at the Administrative
Agent's option.  Each partial prepayment shall be allocated
among the Banks, in proportion, as nearly as practicable, to
the respective unpaid principal amount of each Bank's
Revolving Credit Note, with adjustments to the extent
practicable to equalize any prior repayments not exactly in
proportion.

                Section 4.  THE TERM LOAN.

            Section 4.1.  Commitment to Lend.

            Subject to the terms and conditions set forth in this
Credit Agreement, each Bank agrees to lend to the Borrower
on the Closing Date the amount listed on Schedule 1 hereto
of the principal amount of $45,000,000, provided that if the
PERC Closing Date shall not have occurred on or prior to the
Closing Date, $6,000,000 of such amount will be withheld and
will be provided to the Borrower on the PERC Closing Date,
provided that the Administrative Agent receives evidence
that the PERC Restructuring will be on terms substantially
the same as those set forth in the Borrower s 1997 annual
report, and provided further that the PERC Closing Date will
occur no later than December 31, 1998.  If the PERC
Restructuring has not occurred on such terms by December 31,
1998, the principal amount stated above will be
automatically reduced to $39,000,000.

            Section 4.2.  The Term Notes.

                 (a)  The Term Loan shall be evidenced by separate
            amended and restated promissory notes of the Borrower
            in substantially the form of Exhibit C hereto (each a
            "Term Note"), dated the Closing Date or the effective
            date of any future assignment made pursuant to Section
            19 hereof and completed with appropriate insertions. 
            One Term Note shall be payable to the order of each
            Bank in a principal amount equal to such Bank's Term
            Loan Exposure set forth on Schedule 1 and representing
            the obligation of the Borrower to pay to such Bank such
            principal amount.  The Borrower irrevocably authorizes
            each Bank to make or cause to be made a notation on
            such Bank's Term Note Record reflecting the original
            principal amount of such Bank's Term Loan Exposure and,
            at or about the time of such Bank's receipt of any
            principal payment on such Bank's Term Note, an
            appropriate notation on such Bank's Term Note Record
            reflecting such payment.  The aggregate unpaid amount
            set forth on such Bank's Term Note Record shall, absent
            manifest error, be prima facie evidence of the
            principal amount thereof owing and unpaid to such Bank,
            but the failure to record, or any error in so
            recording, any such amount on such Bank's Term Note
            Record shall not affect the obligations of the Borrower
            hereunder or under any Term Note to make payments of
            principal of and interest on any Term Note when due. 
            Notwithstanding the foregoing, the final principal
            payment shall be adjusted to reflect any amount not
            advanced to the Borrower.

                 (b)  Upon receipt of an affidavit of an officer of
            any Bank as to the loss, theft, destruction or
            mutilation of such Bank's Term Note, and, in the case
            of any such loss, theft, destruction or mutilation,
            upon surrender and cancellation of such Term Note, the
            Borrower will issue, in lieu thereof, a replacement
            Term Note for such Bank in the same principal amount
            thereof and otherwise of like tenor.

            Section 4.3.  Schedule of Installment Payments of
Principal of Term Loan.


The Borrower promises to pay to the Administrative Agent for
the account of the Banks the principal amount of the Term
Loan in three (3) consecutive payments of $3,000,000, such
installments to be due and payable on September 30, 1999,
December 31, 1999, and March 31, 2000, with a final payment
on the Term Loan Maturity Date in an amount equal to the
unpaid balance of the Term Loan.

            Section 4.4.  Optional Prepayment of Term Loan.  

            The Borrower shall have the right at any time to prepay
the Term Notes on or before the Term Loan Maturity Date, as
a whole, or in part, upon not less than three (3) Business
Days prior written notice to the Administrative Agent,
without premium or penalty, provided that (i) each partial
prepayment shall be in the principal amount of $5,000,000 or
in integral multiples of $1,000,000 in excess thereof, and
(ii) each partial prepayment shall be allocated among the
Banks, in proportion, as nearly as practicable, to the
respective outstanding amount of each Bank's Term Note, with
adjustments to the extent practicable to equalize any prior
prepayments not exactly in proportion.  Any prepayment of
principal of the Term Loan shall include all interest
accrued to the date of prepayment and shall be applied
against the scheduled installments of principal due on the
Term Loan in the inverse order of maturity.  No amount
repaid with respect to the Term Loan may be reborrowed.

            Section 4.5.  Mandatory Prepayments of Term Loan.  Upon
the closing of a Generating Asset Transaction, the net cash
proceeds thereof received by the Borrower or any of its
Subsidiaries shall be used to prepay the Term Loan.

 Any prepayment of principal of the Term Loan shall include
all interest accrued to the date of prepayment and shall be
applied against the scheduled installments of principal due
on the Term Loan in the inverse order of maturity.

            Section 4.6.  Interest on Term Loan.

                 Section 4.6.1.  Interest Rates.
                 
                 Except as otherwise provided in Section 6.10, the
            Term Loan shall bear interest during each Interest
            Period relating to all or any portion of the Term Loan
            at the following rates, provided that no interest shall
            accrue on the $6,000,000 holdback until the Banks have
            advanced such amount:

                      (a)  To the extent that all or any portion of
                 the Term Loan bears interest during such Interest
                 Period at the Base Rate, the Term Loan or such
                 portion shall bear interest during such Interest
                 Period at the Base Rate plus the Applicable
                 Margin.

                      (b)  To the extent that all or any portion of
                 the Term Loan bears interest during such Interest
                 Period at the LIBOR Rate, the Term Loan or such
                 portion shall bear interest during such Interest
                 Period at the LIBOR Rate plus the Applicable
                 Margin.

            The Borrower promises to pay interest on the Term Loan
            or any portion thereof outstanding during each Interest
            Period in arrears on each Interest Payment Date
            applicable to such Interest Period.

                 Section 4.6.2.  Notification by Borrower.  

                 The Borrower shall notify the Administrative
            Agent, such notice to be irrevocable, at least three
            (3) LIBOR Business Days prior to the Drawdown Date of
            the Term Loan if all or any portion of the Term Loan is
            to bear interest at the LIBOR Rate.  After the Term
            Loan has been made, the provisions of Section 2.7 shall
            apply mutatis mutandis with respect to all or any
            portion of the Term Loan so that the Borrower may have
            the same interest rate options with respect to all or
            any portion of the Term Loan as it would be entitled to
            with respect to the Revolving Credit Loans.

                 Section 4.6.3.  Amounts, etc.

                 Any portion of the Term Loan bearing interest at
            the LIBOR Rate relating to any Interest Period shall be
            in the amount of $500,000 or an integral multiple
            thereof.  No Interest Period relating to the Term Loan
            or any portion thereof bearing interest at the LIBOR
            Rate shall extend beyond the date on which a regularly
            scheduled installment payment of the principal of the
            Term Loan is to be made unless a portion of the Term
            Loan at least equal to the amount of such installment
            payment has an Interest Period ending on such date or
            is then bearing interest at the Base Rate.

                              Section 5.  LETTERS OF CREDIT.

            Section 5.1.  Letter of Credit Commitments.

                 Section 5.1.1.  Commitment to Issue Letters of
            Credit.   

            Subject to the terms and conditions hereof and the
execution and delivery by the Borrower of a letter of credit
application on the Administrative Agent's customary form (a
"Letter of Credit Application"), the Administrative Agent on
behalf of the Banks and in reliance upon the agreement of
the Banks set forth in Section 5.1.4 and upon the
representations and warranties of the Borrower contained
herein, agrees, in its individual capacity, to issue, extend
and renew for the account of the Borrower one or more
standby or documentary letters of credit (individually, a
"Letter of Credit"), in such form as may be requested from
time to time by the Borrower and agreed to by the
Administrative Agent; provided, however, that, after giving
effect to such request, (a) the sum of the aggregate Maximum
Drawing Amount and all Unpaid Reimbursement Obligations
shall not exceed $15,000,000 at any one time and (b) the sum
of (i) the Maximum Drawing Amount on all Letters of Credit,
(ii) all Unpaid Reimbursement Obligations, and (iii) the
amount of all Revolving Credit Loans outstanding shall not
exceed the Total Commitment.  Any Letter of Credit requested
by the Borrower hereunder shall not be required to be issued
by the Administrative Agent earlier than (x) three Business
Days after its receipt of a Letter of Credit Application
therefor in the case of Letters of Credit issued in support
of the Pollution Control Revenue Bonds or (y) one Business
Day after its receipt of a Letter of Credit Application
therefor in the case of Letters of Credit issued in
connection with fuel hedge contracts, and all such other
certificates, documents and other papers and information
relating thereto.

                 Section 5.1.2.  Letter of Credit Applications.  

                 Each Letter of Credit Application shall be
            completed to the satisfaction of the Administrative
            Agent.  In the event that any provision of any Letter
            of Credit Application shall be inconsistent with any
            provision of this Credit Agreement, then the provisions
            of this Credit Agreement shall, to the extent of any
            such inconsistency, govern.

                 Section 5.1.3.  Terms of Letters of Credit.  

                 Each Letter of Credit issued, extended or renewed
            hereunder shall, among other things, (i) provide for
            the payment of sight drafts for honor thereunder when
            presented in accordance with the terms thereof and when
            accompanied by the documents described therein, and
            (ii) have an expiry date no later than the Revolving
            Credit Loan Maturity Date. Each Letter of Credit so
            issued, extended or renewed shall be subject to the
            Uniform Customs.

                 Section 5.1.4.  Reimbursement Obligations of
            Banks.  

                 Each Bank severally agrees that it shall be
            absolutely liable, without regard to the occurrence of
            any Default or Event of Default or any other condition
            precedent whatsoever, to the extent of such Bank's
            Commitment Percentage, to reimburse the Administrative
            Agent on demand for the amount of each draft paid by
            the Administrative Agent under each Letter of Credit to
            the extent that such amount is not reimbursed by the
            Borrower pursuant to Section 5.2 (such agreement for a
            Bank being called herein the "Letter of Credit
            Participation" of such Bank).

                 Section 5.1.5.  Participations of Banks.  

                 Each such payment made by a Bank shall be treated
            as the purchase by such Bank of a participating
            interest in the Borrower's Reimbursement Obligation
            under Section 5.2 in an amount equal to such payment. 
            Each Bank shall share in accordance with its
            participating interest in any interest which accrues
            pursuant to Section 5.2.

            Section 5.2.  Reimbursement Obligation of the
Borrower.  

            In order to induce the Administrative Agent to issue,
extend and renew each Letter of Credit and the Banks to
participate therein, the Borrower hereby agrees to reimburse
or pay to the Administrative Agent, for the account of the
Administrative Agent or (as the case may be) the Banks, with
respect to each Letter of Credit issued, extended or renewed
by the Administrative Agent hereunder,

                 (a)  except as otherwise expressly provided in
            Section 5.2(b) and (c), and upon notice thereof from
            the Administrative Agent, on each date that any draft
            presented under such Letter of Credit is honored by the
            Administrative Agent, or the Administrative Agent
            otherwise makes a payment with respect thereto, (i) the
            amount paid by the Administrative Agent under or with
            respect to such Letter of Credit, and (ii) the amount
            of any taxes, fees, charges or other costs and expenses
            whatsoever incurred by the Administrative Agent or any
            Bank in connection with any payment made by the
            Administrative Agent or any Bank under, or with respect
            to, such Letter of Credit,

                 (b)  upon the reduction (but not termination) of
            the Total Commitment to an amount less than the Maximum
            Drawing Amount, an amount equal to such difference,
            which amount shall be held by the Administrative Agent
            for the benefit of the Banks and the Administrative
            Agent as cash collateral for all Reimbursement
            Obligations, and

                 (c)  upon the termination of the Total Commitment,
            or the acceleration of the Reimbursement Obligations
            with respect to all Letters of Credit in accordance
            with Section 14, an amount equal to the then Maximum
            Drawing Amount on all Letters of Credit, which amount
            shall be held by the Administrative Agent for the
            benefit of the Banks and the Administrative Agent as
            cash collateral for all Reimbursement Obligations.

Each such payment shall be made to the Administrative Agent
at the Administrative Agent's Head Office in immediately
available funds.  Interest on any and all amounts remaining
unpaid by the Borrower under this Section 5.2 at any time
from the date such amounts become due and payable (whether
as stated in this Section 5.2, by acceleration or otherwise)
until payment in full (whether before or after judgment)
shall be payable to the Administrative Agent on demand at
the rate specified in Section 6.10 for overdue principal on
the Revolving Credit Loans.

            Section 5.3.  Letter of Credit Payments.     

If any draft shall be presented or other demand for payment
shall be made under any Letter of Credit, the Administrative
Agent shall promptly notify the Borrower of the date and
amount of the draft presented or demand for payment and of
the date and time when it expects to pay such draft or honor
such demand for payment.  If the Borrower fails to reimburse
the Administrative Agent as provided in Section 5.2 on or
before the date that such draft is paid or other payment is
made by the Administrative Agent, the Administrative Agent
may at any time thereafter notify the Banks of the amount of
any such Unpaid Reimbursement Obligation.  No later than
3:00 p.m. (Boston time) on the Business Day next following
the receipt of such notice, each Bank shall make available
to the Administrative Agent, at the Administrative Agent's
Head Office, in immediately available funds, such Bank's
Commitment Percentage of such Unpaid Reimbursement
Obligation, together with an amount equal to the product of
(i) the average, computed for the period referred to in
clause (iii) below, of the weighted average interest rate
paid by the Administrative Agent for federal funds acquired
by the Administrative Agent during each day included in such
period, times (ii) the amount equal to such Bank's
Commitment Percentage of such Unpaid Reimbursement
Obligation, times (iii) a fraction, the numerator of which
is the number of days that elapse from and including the
date the Administrative Agent paid the draft presented for
honor or otherwise made payment to the date on which such
Bank's Commitment Percentage of such Unpaid Reimbursement
obligation shall become immediately available to the
Administrative Agent, and the denominator of which is 360. 
The responsibility of the Administrative Agent to the
Borrower and the Banks shall be only to determine that the
documents (including each draft) delivered under each Letter
of Credit in connection with such presentment shall be in
conformity in all material respects with such Letter of
Credit.

            Section 5.4.  Obligations Absolute.     

The Borrower's obligations under this Section 5 shall be
absolute and unconditional under any and all circumstances
and irrespective of the occurrence of any Default or Event
of Default or any condition precedent whatsoever or any
setoff, counterclaim or defense to payment which the
Borrower may have or have had against the Administrative
Agent, any Bank or any beneficiary of a Letter of Credit. 
The Borrower further agrees with the Administrative Agent
and the Banks that  the Administrative Agent and the Banks
shall not be responsible for, and the Borrower's
Reimbursement Obligations under Section 5.2 shall not be
affected by, among other things, the validity or genuineness
of documents or of any endorsements thereon, even if such
documents should in fact prove to be in any or all respects
invalid, fraudulent or forged, or any dispute between or
among the Borrower, the beneficiary of any Letter of Credit
or any financing institution or other party to which any
Letter of Credit may be transferred or any claims or
defenses whatsoever of the Borrower against the beneficiary
of any Letter of Credit or any such transferee.  The
Administrative Agent and the Banks shall not be liable for
any error, omission, interruption or delay in transmission,
dispatch or delivery of any message or advice, however
transmitted, in connection with any Letter of Credit, except
to the extent resulting from the gross negligence or willful
misconduct on the part of the Administrative Agent or any of
the Banks.  The Borrower agrees that any action taken or
omitted by the Administrative Agent or any Bank under or in
connection with each Letter of Credit and the related drafts
and documents, if done in good faith, shall be binding upon
the Borrower and shall not result in any liability on the
part of the Administrative Agent or any Bank to the
Borrower, except to the extent resulting from the gross
negligence or willful misconduct on the part of the
Administrative Agent or any of the Banks.

            Section 5.5.  Reliance by Issuer.       

To the extent not inconsistent with Section 5.4, the
Administrative Agent shall be entitled to rely, and shall be
fully protected in relying upon, any Letter of Credit,
draft, writing, resolution, notice, consent, certificate,
affidavit, letter, cablegram, telegram, telecopy, telex or
teletype message, statement, order or other document
believed by it in good faith to be genuine and correct and
to have been signed, sent or made by the proper Person or
Persons and upon advice and statements of legal counsel,
independent accountants and other experts selected by the
Administrative Agent.  The Administrative Agent shall be
fully justified in failing or refusing to take any action
under this Credit Agreement unless it shall first have
received such advice or concurrence of the Majority Banks as
it reasonably deems appropriate or it shall first be
indemnified to its reasonable satisfaction by the Banks
against any and all liability and expense which may be
incurred by it by reason of taking or continuing to take any
such action.  The Administrative Agent shall in all cases be
fully protected in acting, or in refraining from acting,
under this Credit Agreement in accordance with a request of
the Majority Banks, and such request and any action taken or
failure to act pursuant thereto shall be binding upon the
Banks and all future holders of the Revolving Credit Notes
or of a Letter of Credit Participation.

            Section 5.6.  Letter of Credit Fee.     

The Borrower shall, on the date of issuance or any extension
or renewal of any Letter of Credit pay a fee (in each case,
a "Letter of Credit Fee") to the Administrative Agent (i) in
respect of each standby Letter of Credit an amount equal to
the Applicable L/C Rate of the face amount of such standby
Letter of Credit, plus an amount equal to one-eighth percent
(1/8%) per annum of the face amount of such standby Letter
of Credit which shall be for the account of the
Administrative Agent, as a fronting fee, and the balance of
which Letter of Credit Fee shall be for the accounts of the
Banks in accordance with their respective Commitment
Percentages.  In respect of each Letter of Credit, the
Borrower shall also pay to the Administrative Agent for the
Administrative Agent's own account, at such other time or
times as such charges are customarily made by the
Administrative Agent, the Administrative Agent's customary
issuance, amendment, negotiation or document examination and
other administrative fees as in effect from time to time.

            Section 5.7.  Letter of Credit Standard of Care.  The
Borrower agrees that any action taken or omitted by the
Administrative Agent under or in connection with any Letter
of Credit or the related drafts or documents, if done in the
absence of gross negligence or willful misconduct and in
accordance with the standards of care specified in the
Uniform Commercial Code of the State of New York, shall be
binding on the Borrower and shall not result in any
liability of the Administrative Agent to the Borrower.

                 Section 6.  CERTAIN GENERAL PROVISIONS.

            Section 6.1.  Fees.      

The Borrower agrees to pay to the Administrative Agent, for
the account of the Administrative Agent and the
Documentation Agent, all fees at the times and in the
amounts set forth the fee letter dated June 1, 1998 among
the Borrower, the Administrative Agent, the Documentation
Agent and BancBoston Securities Inc. (the "Fee Letter").

            Section 6.2.  Funds for Payments.

                 Section 6.2.1.  Payments to Administrative
            Agent.

                 All payments of principal, interest, Reimbursement
            Obligations, commitment fees, Letter of Credit Fees and
            any other amounts due hereunder or under any of the
            other Loan Documents shall be made to the
            Administrative Agent, for the respective accounts of
            the Banks and the Administrative Agent, at the
            Administrative Agent's Head Office or at such other
            location in the Boston, Massachusetts, area that the
            Administrative Agent may from time to time designate in
            a notice to the Borrower, in each case in immediately
            available funds.

                 Section 6.2.2.  No Offset, etc.


                 All payments by the Borrower hereunder and under
            any of the other Loan Documents shall be made without
            recoupment, setoff or counterclaim and free and clear
            of and without deduction for any income, stamp or other
            taxes, levies, imposts, duties, charges, fees,
            deductions, withholdings, now or hereafter imposed,
            levied or collected, withheld or assessed by any
            governmental authority, agency or instrumentality
            excluding, in the case of the Administrative Agent and
            each Bank, net income and franchise taxes imposed on
            the Administrative Agent or such Bank by the
            jurisdiction under the laws of which such
            Administrative Agent or such Bank is organized or any
            political subdivision thereof or taxing or other
            authority therein unless the Borrower is compelled by
            law to make such deduction or withholding.  If any such
            obligation is imposed upon the Borrower with respect to
            any amount payable by it hereunder or under any of the
            other Loan Documents, the Borrower will pay to the
            Administrative Agent, for the account of the Banks or
            (as the case may be) the Administrative Agent, on the
            date on which such amount is due and payable hereunder
            or under such other Loan Document, such additional
            amount in Dollars as shall be necessary to enable the
            Banks or the Administrative Agent to receive the same
            net amount which the Banks or the Administrative Agent
            would have received on such due date had no such
            obligation been imposed upon the Borrower.  The
            Borrower will deliver promptly to the Administrative
            Agent, to the extent available, certificates  or other
            valid vouchers for all taxes or other charges deducted
            from or paid with respect to payments made by the
            Borrower hereunder or under such other Loan Document,
            provided however that the foregoing obligation to pay
            such additional amounts shall not apply:

                      (i)  to any payment to a Bank if such Bank is
                 not, on the date hereof (or on the date it becomes
                 a Bank under this Agreement) and on the date of
                 any change in the lending office of such Bank
                 identified after its execution, entitled by virtue
                 of its status as a non-resident alien to submit
                 either a Form 1001 (relating to such Bank and
                 entitling it to a complete exemption from
                 withholding on all interest to be received by it
                 hereunder in respect of the Loans) or Form 4224
                 (relating to all interest to be received by such
                 Bank hereunder in respect of Loans) of the U.S.
                 Department of Treasury, or

                      (ii) to any item referred to in the preceding
                 sentence that would not have been imposed but for
                 the failure by such Bank to comply with applicable
                 certification, information, documentation or other
                 reporting requirements concerning the nationality,
                 residence, identity or connections of such Bank
                 with the United States if such compliance is
                 required by statute or regulation of the United
                 States as a precondition to relief or exemption
                 from such item.

            Section 6.3.  Computations.   

All computations of interest on the Loans and of commitment
fees, Letter of Credit Fees or other fees shall, unless
otherwise expressly provided herein, be calculated on the
basis of a 360-day year for the actual days elapsed, and all
computations of interest on any Base Rate Loan shall be
calculated on the basis of a 365- (or 366-, as the case may
be) day year for the actual days elapsed.  Except as
otherwise provided in the definition of the term "Interest
Period" with respect to LIBOR Rate Loans, whenever a payment
hereunder or under any of the other Loan Documents becomes
due on a day that is not a Business Day, the due date for
such payment shall be extended to the next succeeding
Business Day, and interest shall accrue during such
extension.  The outstanding amount of the Loans as reflected
on the Revolving Credit Note Records and the Term Note
Records from time to time shall, absent manifest error, be
considered correct and binding on the Borrower unless within
five (5) Business Days after receipt of any notice by the
Administrative Agent or any of the Banks of such outstanding
amount, the Administrative Agent or such Bank shall notify
the Borrower to the contrary.

            Section 6.4.  Inability to Determine LIBOR
Rate.       

In the event, prior to the commencement of any Interest
Period relating to any LIBOR Rate Loan, the Administrative
Agent shall determine or be notified by the Majority Banks
that adequate and reasonable methods do not exist for
ascertaining the LIBOR Rate that would otherwise determine
the rate of interest to be applicable to any LIBOR Rate Loan
during any Interest Period, the Administrative Agent shall
forthwith give notice of such determination (which shall be
conclusive and binding on the Borrower and the Banks) to the
Borrower and the Banks.  In such event (i) any Loan Request
or Conversion Request with respect to LIBOR Rate Loans shall
be automatically withdrawn and shall be deemed a request for
Base Rate Loans, (ii) each LIBOR Rate Loan will
automatically, on the last day of the then current Interest
Period relating thereto, become a Base Rate Loan, and (iii)
the obligations of the Banks to make LIBOR Rate Loans shall
be suspended until the Administrative Agent determines that
the circumstances giving rise to such suspension no longer
exist, whereupon the Administrative Agent shall so notify
the Borrower and the Banks.

            Section 6.5.  Illegality.     

Notwithstanding any other provisions herein, if subsequent
to the Closing Date, the adoption of or change in any
present or future law, regulation, treaty or directive or in
the interpretation or application thereof shall make it
unlawful for any Bank to make or maintain LIBOR Rate Loans,
such Bank shall forthwith give notice of such circumstances
to the Borrower and the other Banks and thereupon (i) the
commitment of such Bank to make LIBOR Rate Loans or convert
Loans of another Type to LIBOR Rate Loans shall forthwith be
suspended and (ii) such Bank's Revolving Credit Loans then
outstanding as LIBOR Rate Loans, if any, shall be converted
automatically to Base Rate Loans on the last day of each
Interest Period applicable to such LIBOR Rate Loans or
within such earlier period as may be required by law.  The
Borrower hereby agrees promptly to pay the Administrative
Agent for the account of such Bank, upon demand by such
Bank, any additional amounts as may be required pursuant to
Section 6.9.

            Section 6.6.  Additional Costs, etc.    

If subsequent to the Closing Date, the adoption of or change
in any present or future applicable law, which expression,
as used herein, includes statutes, rules and regulations
thereunder and interpretations thereof by any competent
court or by any governmental or other regulatory body or
official charged with the administration or the
interpretation thereof and requests, directives,
instructions and notices at any time or from time to time
hereafter made upon or otherwise issued to any Bank or the
Administrative Agent by any central bank or other fiscal,
monetary or other authority (whether or not having the force
of law), shall:

                 (a)  subject any Bank or the Administrative Agent
            to any tax, levy, impost, duty, charge, fee, deduction
            or withholding of any nature with respect to this
            Credit Agreement, the other Loan Documents, any Letters
            of Credit, such Bank's Revolving Credit Note or Term
            Note, such Bank s Commitment or the Loans (other than
            taxes based upon or measured by the income or profits
            of such Bank or the Administrative Agent or any
            franchise tax imposed by such Bank s or the
            Administrative Agent s jurisdiction of incorporation or
            organization, or the location of its lending office,
            hereinafter referred to as "Income Taxes"), or

                 (b)  materially change the basis of taxation
            (except for changes in Income Taxes) of payments to any
            Bank of the principal of or the interest on its Notes
            or any other amounts payable to any Bank or the
            Administrative Agent under this Credit Agreement or any
            of the other Loan Documents, or

                 (c)  impose or increase or render applicable
            (other than to the extent specifically provided for
            elsewhere in this Credit Agreement) any special
            deposit, reserve, assessment, liquidity, capital
            adequacy or other similar requirements (whether or not
            having the force of law) against assets held by, or
            deposits in or for the account of, or loans by, or
            letters of credit issued by, or commitments of an
            office of any Bank, or

                 (d)  impose on any Bank or the Administrative
            Agent any other conditions or requirements with respect
            to this Credit Agreement, the other Loan Documents, any
            Letters of Credit, or such Bank's Notes, and the result
            of any of the foregoing is

                      (i)  to increase the cost to any Bank of
                 making, funding, issuing, renewing, extending or
                 maintaining such Bank's Notes or any Letter of
                 Credit, or

                      (ii)  to reduce the amount of principal,
                 interest, Reimbursement Obligation or other amount
                 payable to such Bank or the Administrative Agent
                 hereunder on account of such Bank's Notes or any
                 Letter of Credit, or

                      (iii)  to require such Bank or the
                 Administrative Agent to make any payment or to
                 forego any interest or Reimbursement Obligation or
                 other sum payable hereunder, the amount of which
                 payment or foregone interest or Reimbursement
                 Obligation or other sum is calculated by reference
                 to the gross amount of any sum receivable or
                 deemed received by such Bank or the Administrative
                 Agent from the Borrower hereunder,

then, and in each such case, the Borrower will, upon demand
made by such Bank or (as the case may be) the Administrative
Agent at any time and from time to time and as often as the
occasion therefor may arise, pay to such Bank or the
Administrative Agent such additional amounts as will be
sufficient to compensate such Bank or the Administrative
Agent for such additional cost, reduction, payment or
foregone interest or Reimbursement Obligation or other sum.

            Section 6.7.  Capital Adequacy.    

If after the date hereof any Bank determines that (i) the
adoption of or change in any law, governmental rule,
regulation, policy, guideline or directive (whether or not
having the force of law) regarding capital requirements for
banks or bank holding companies or any change in the
interpretation or application thereof by a court or
governmental authority with appropriate jurisdiction, in
each case subsequent to the Closing Date, or (ii) compliance
by such Bank or any corporation controlling such Bank with
any such adoption of or change in, law, governmental rule,
regulation, policy, guideline or directive (whether or not
having the force of law) of any such entity regarding
capital adequacy, has the effect of reducing the return on
such Bank's Notes to a level below that which such Bank
could have achieved but for such adoption, change or
compliance (taking into consideration such Bank's then
existing policies with respect to capital adequacy and
assuming full utilization of such entity's capital) by any
amount deemed by such Bank to be material, then such Bank
may notify the Borrower of such fact.  To the extent that
the amount of such reduction in the return on capital is not
reflected in the Base Rate, the Borrower and such Bank shall
thereafter attempt to negotiate in good faith, within thirty
(30) days of the day on which the Borrower receives such
notice, an adjustment payable hereunder that will adequately
compensate such Bank in light of these circumstances.  If
the Borrower and such Bank are unable to agree to such
adjustment within thirty (30) days of the date on which the
Borrower receives such notice, then commencing on the date
of such notice (but not earlier than the effective date of
any such increased capital requirement), the fees payable
hereunder shall increase by an amount that will, in such
Bank's reasonable determination, provide adequate
compensation.  Each Bank shall allocate such cost increases
among its customers in good faith and on an equitable basis.

            Section 6.8.  Certificate.    

Each Bank shall notify the Borrower of any event entitling
such Bank to compensation under Section 6.6 or 6.7 as
promptly as practicable, but in any event within 60 days,
after such Bank obtains actual knowledge thereof; provided
that (i) if any Bank fails to give such notice within
60 days after it obtains actual knowledge of such an event,
such Bank shall, with respect to compensation payable
pursuant to Section 6.6 or 6.7 in respect of any costs
resulting form such event, only be entitled to payment under
such Section 6.6 or 6.7, as applicable, for costs incurred
from and after the date 60 days prior to the date that such
Bank does give such notice and (ii) each Bank will designate
a different lending office for the Loans of such Bank if
such designation will avoid the need for, or reduce the
amount of, such compensation and will not, in the sole
opinion of such Bank, be disadvantageous to such Bank.  A
certificate setting forth any additional amounts payable
pursuant to Section 6.6 or 6.7 and a brief explanation of
such amounts which are due, submitted by any Bank or the
Agent to the Borrower, shall be conclusive, absent manifest
error, that such amounts are due and owing.

     Section 6.9.  Reasonable Efforts to Mitigate.       

Each Bank agrees that as promptly as practicable after it
becomes aware of the occurrence of an event or the existence
of a condition that would cause it to be affected under
Section Section 6.4, 6.5, 6.6 or 6.7, such Bank will give
notice thereof to the Borrower, with a copy to the
Administrative Agent, and, to the extent so requested by the
Borrower and not inconsistent with such Bank's internal
policies, such Bank shall use reasonable efforts and take
such actions as are reasonably appropriate if as a result
thereof the additional moneys which would otherwise be
required to be paid to such Bank pursuant to such subSection
s would be materially reduced, or the illegality or other
adverse circumstances which would otherwise require a
conversion of such Loans or result in the inability to make
such Loans pursuant to such Section s would cease to exist,
and in each case if, as determined by such Bank in its sole
discretion, the taking such actions would not adversely
affect such Loans or such Bank or otherwise be
disadvantageous to such Bank.  To the extent practicable and
applicable, each Bank shall allocate such cost increases
among its customers in good faith and on an equitable basis.

            Section 6.10.  Indemnity.     

The Borrower agrees to indemnify each Bank and to hold each
Bank harmless from and against any loss, cost or expense
(including, such loss or expense associated with terminating
any interest rate protection arrangements entered into
between the Borrower and any Bank) that such Bank may
sustain or incur as a consequence of (i) default by the
Borrower in payment of the principal amount of or any
interest on any LIBOR Rate Loans as and when due and
payable, including any such loss or expense arising from
interest or fees payable by such Bank to lenders of funds
obtained by it in order to maintain its LIBOR Rate Loans,
(ii) default by the Borrower in making a borrowing or
conversion after the Borrower has given (or is deemed to
have given) a Loan Request, notice (in the case of all or
any portion of the Term Loan pursuant to Section 4.6.2) or a
Conversion Request relating thereto in accordance with
Section 2.6 or Section 2.7 (other than as a result of the
operation of Section 6.4) or (iii) the making of any payment
of a LIBOR Rate Loan or the making of any conversion of any
such Loan to a Base Rate Loan on a day that is not the last
day of the applicable Interest Period with respect thereto,
including interest or fees payable by such Bank to lenders
of funds obtained by it in order to maintain any such Loans.
Such loss or reasonable expense shall exclude any loss of
profits or margin applicable to such LIBOR Rate Loan but
shall include an amount equal to the excess, if any, as
reasonably determined by each Bank of (i) its cost of
obtaining the funds for the LIBOR Rate Loan being paid,
prepaid, converted, not converted, or not borrowed, as the
case may be (based on the LIBOR Rate) for the period from
the date of such payment, prepayment, conversion, or failure
to borrow or convert, as the case may be, to the last day of
the Interest Period for such portion of the Term Loan (or,
in the case of a failure to borrow, the Interest Period for
such portion of the Term Loan which would have commenced on
the date of such failure to borrow) over (ii) the amount of
interest (as reasonably determined by such Bank) that would
be realized by such Bank in re-employing the funds so paid,
prepaid, converted, or not borrowed, converted, or prepaid
for such period or Interest Period, as the case may be,
which determinations shall be prima facie correct and
binding, absent manifest error.

            Section 6.11.  Interest After Default.

                 Section 6.11.1.  Overdue Amounts.  

                 Overdue principal and (to the extent permitted by
            applicable law) interest on the Loans or fees payable
            hereunder or under any of the other Loan Documents
            shall, following the expiration of the applicable grace
            period, if any, bear interest compounded monthly and
            payable on demand at a rate per annum equal to two
            percent (2.00%) above the Base Rate plus the Applicable
            Margin until such amount shall be paid in full (after
            as well as before judgment).

                 Section 6.11.2.  Replacement Banks; Mitigation.

                      (a)  Within thirty (30) days after (i) any
                 Bank has demanded compensation from the Borrower
                 pursuant to Section Section 6.2.2, 6.6 or 6.7
                 hereof, or (ii) there shall have occurred a change
                 in law with respect to any Bank as a consequence
                 of which it shall become unlawful for such Bank to
                 make a LIBOR Rate Loan on any Drawdown Date, as
                 described in the previous Section 6.5 (any such
                 Bank described in the foregoing clauses (i) or
                 (ii) is hereinafter defined as an "Affected
                 Bank"), the Borrower may request that the other
                 Banks (the "Non-Affected Banks") acquire all, but
                 not less than all, of the Affected Bank s Notes
                 and assume all, but not less than all, of the
                 Affected Bank s Notes.  If the Borrower so
                 requests, the Non-Affected Banks may elect to
                 acquire all of the Affected Bank s Notes and
                 assume all of the Affected Bank s Notes.  If the
                 Non-Affected Banks do not elect to acquire and
                 assume all of the Affected Bank s Notes, the
                 Borrower may designate a replacement bank or banks
                 (which must be an Eligible Assignee), which must
                 be reasonably satisfactory to the Agent, to
                 acquire and assume that portion of the Notes of
                 the Affected Bank not being acquired and assumed
                 by the Non-Affected Banks.  The provisions of
                 Section 19 hereof shall apply to all reallocations
                 pursuant to this Section 6.10.2, and the Affected
                 Bank and the Non-Affected Banks and/or replacement
                 banks which are to acquire the Notes of the
                 Affected Bank shall execute and deliver to the
                 Agent, in accordance with the provisions of
                 Section 19 hereof, such Assignments and
                 Acceptances and other instruments, as are required
                 pursuant to Section 19 hereof to give effect to
                 such reallocations; provided, however, the
                 Borrower shall, or shall cause the assignee Bank
                 to pay, the registration fee set forth in Section
                 19.3.  On the effective date of the applicable
                 Assignment and Acceptances, the Borrower shall pay
                 to the Affected Bank all interest accrued on its
                 Notes up to but excluding such date, along with
                 any fees payable to such Affected Bank hereunder
                 up to but excluding such date, including, without
                 limitation, any amounts that would have been
                 payable pursuant to Section 6.9 hereof in
                 connection with prepayment.

                      (b)  If (i) any Bank shall request
                 compensation under Section 6.6 or Section 6.7
                 hereof, (ii) any Bank deliver a notice described
                 in Section 6.5 hereof or (iii) the Borrower is
                 required to pay any additional amount to any Bank
                 or any governmental authority on account of the
                 Bank pursuant to Section 6.2.2 or Section 6.6,
                 such Bank agrees to use reasonable efforts
                 (consistent with legal policy and regulatory
                 restrictions) to change its Domestic Lending
                 Office or LIBOR Lending Office, as the case may
                 be, to avoid or minimize any amounts otherwise
                 payable under Section Section 6.2.2, 6.6 or 6.7 or
                 enable it to withdraw a notice given pursuant to
                 Section 6.5, in each case solely if such change
                 can be made in a manner so that such Bank, in its
                 sole determination, suffers no legal, economic or
                 regulatory disadvantage deemed by such Bank in its
                 sole discretion to be significant.

                 Section 7.  COLLATERAL SECURITY.

            Section 7.1.  Security of Borrower.  

            The Obligations shall be secured by a perfected first
priority security interest (subject only to Permitted Liens)

Bangor Energy Intercreditor Agreement), pursuant to the
terms of the Security Documents to which the Borrower is a
party.

            effect on the business, assets or financial condition
            of the Borrower and its Subsidiaries, taken as a whole.

                 Section 8.1.2.  Authorization.

sufficient title to all real property and all machinery and
equipment owned by it and owns or possesses adequate rights

necessary tot he conduct of its business, all free and clear
of liens other than Permitted Liens.  The Borrower enjoys

            Section 8.4.  Financial Statements and Projections.

                 Section 8.4.1.  Fiscal Year.       

            The Borrower and each of its Subsidiaries has a fiscal
year which is the twelve months ending on December 31 of
each calendar year.

                 Section 8.4.2.  Financial Statements.  

                 There has been furnished to the Administrative
            Agent a consolidated balance sheet of the Borrower and
            its Subsidiaries as at the Company Balance Sheet Date,
            and a consolidated statement of income of the Borrower
            and its Subsidiaries for the fiscal year then ended,
            certified by Coopers & Lybrand.  Such balance sheet and
            statement of income have been prepared in accordance
            with GAAP and fairly present in all material respects
            the financial condition of the Borrower as at the close
            of business on the date thereof and the results of
            operations for the fiscal year then ended.  There are
            no contingent liabilities of the Borrower or any of its
            Subsidiaries as of such date involving material
            amounts, known to the officers of the Borrower, which
            were not disclosed in such balance sheet and the notes
            related thereto or in the Disclosure Documents.

                 Section 8.4.3.  Projections.  

                 The projections of the annual operating budgets of
            the Borrower, balance sheets and cash flow statements
            for the fiscal years 1998 to 2001, copies of which have
            been delivered to the Administrative Agent, disclose
            all material assumptions made with respect to general
            economic, financial and market conditions used in
            formulating such projections.  To the knowledge of the
            Borrower, no facts exist that (individually or in the
            aggregate) would result in any material change in any
            of such projections.  The projections are based upon
            reasonable estimates and assumptions, have been
            prepared on the basis of the assumptions stated therein
            and reflect the reasonable estimates of the Borrower of
            the results of operations and other information
            projected therein.  Notwithstanding the foregoing, the
            Administrative Agent and the Banks recognize that such
            projections as to future events are not to be viewed as
            facts and that actual results during the period covered
            may differ from the projected results.

            Section 8.5.  No Material Changes, etc.      

Since the Company Balance Sheet Date there has occurred no
materially adverse change in the financial condition or
business of the Borrower and its Subsidiaries as shown on or
reflected in the consolidated balance sheet of the Borrower
and its Subsidiaries as at the Company Balance Sheet Date,
or the consolidated statement of income for the fiscal year
then ended, other than changes in the ordinary course of
business that have not had any materially adverse effect on
the business or financial condition of the Borrower or any
of its Subsidiaries.  Since the Company Balance Sheet Date,
the Borrower has not made any Distribution other than (a) as
permitted pursuant to Section 11.4 and disclosed to the
Banks, or (b) Distributions with respect to preferred stock.

            Section 8.6.  Franchises, Patents, Copyrights,
etc.        

Each of the Borrower and its Subsidiaries possesses all
franchises, patents, copyrights, trademarks, trade names,
licenses and permits, and rights in respect of the
foregoing, adequate for the conduct of its business
substantially as now conducted without known conflict with
any rights of others.

            Section 8.7.  Litigation.  As of the Closing Date,
            

   except as set forth in Schedule 8.7 hereto, there are no
actions, suits, proceedings or investigations of any kind
pending or threatened in writing against the Borrower or any
of its Subsidiaries before any court, tribunal or
administrative agency or board that, if adversely
determined, might, either in any case or in the aggregate,
materially adversely affect the properties, assets,
financial condition or business of the Borrower and its
Subsidiaries as a whole, or result in any substantial
liability not adequately covered by insurance, or for which
adequate reserves are not maintained on the consolidated
balance sheet of the Borrower and its Subsidiaries, or which
question the validity of this Credit Agreement or any of the
other Loan Documents, or any action taken or to be taken
pursuant hereto or thereto.

            Section 8.8.  No Materially Adverse Contracts,
etc.  Except as disclosed in the Disclosure Documents,
n           

  either the Borrower nor any of its Subsidiaries is subject
to any charter, corporate or other legal restriction, or any
judgment, decree, order, rule or regulation that has or is
expected, in the judgement of the Borrower s officers to
have a materially adverse effect on the business, assets or
financial condition of the Borrower and its Subsidiaries
taken as a whole.  Neither the Borrower nor any of its
Subsidiaries is a party to any contract or agreement that
has or is expected, in the judgment of the Borrower's
officers, to have any materially adverse effect on the
business of the Borrower and its Subsidiaries, taken as a
whole.

            Section 8.9.  Compliance with Other Instruments, Laws,
etc.  

            Neither the Borrower nor any of its Subsidiaries is in
violation of any provision of its charter documents, bylaws,
or any agreement or instrument to which it is subject or by
which it or any of its properties is bound or any decree,
order, judgment, statute, license, rule or regulation, in
any of the foregoing cases in a manner that would materially
and adversely affect the financial condition, properties or
business of the Borrower and its Subsidiaries, taken as a
whole.

            Section 8.10.  Tax Status.    

The Borrower has made or filed all federal and state income
and all other material tax returns, reports and declarations
required by any jurisdiction to which it is subject; has
paid all taxes and other governmental assessments and
charges shown or determined to be due on such returns,
reports and declarations, except those being contested in
good faith and by appropriate proceedings; and has set aside
on its books provisions reasonably adequate for the payment
of all taxes for periods subsequent to the periods to which
such returns, reports or declarations apply in accordance
with GAAP.  There are no unpaid taxes in any material amount
claimed to be due by the taxing authority of any
jurisdiction, and the officers of the Borrower know of no
basis for any such claim.

            Section 8.11.  No Event of Default.     

No Default or Event of Default has occurred and is
continuing.

            Section 8.12.  Holding Company Act.  The Borrower is
exempt from the provisions of the Public Utility Holding
Company Act of 1935 and the rules promulgated thereunder
other than Section  9(a)(2) thereof, and is not a
"subsidiary" or an "affiliate" of any "holding company" as
such terms are defined in the act.  The Borrower is not
subject to any other law, rule or regulation which in any
way restricts its ability to incur Indebtedness pursuant to
this Credit Agreement.

            Section 8.13.  Absence of Financing Statements, etc.  

            Except with respect to Permitted Liens, there is no
financing statement, security agreement, chattel mortgage,
real estate mortgage or other document filed or recorded
with any filing records, registry or other public office,
that purports to cover, affect or give notice of any present
or possible future lien on, or security interest in, any
assets or property of the Borrower or any of its
Subsidiaries or any rights relating thereto.

            Section 8.14.  Perfection of Security Interest.   

All filings, assignments, pledges and deposits of documents
or instruments have been made and all other actions have
been taken that are necessary, under applicable law, to
establish and perfect the Administrative Agent's security
interest in the Collateral Bonds.  The Collateral Bonds and
the Administrative Agent's rights with respect to the 
Collateral Bonds are not subject to any setoff, claims,
withholdings or other defenses.  The Collateral Bonds are
free from any lien, security interest, encumbrance and any
other claim or demand, except for Permitted Liens.

            Section 8.15.  Certain Transactions.    

Except for the transactions expressly contemplated by the
Acquisition Documents and except for arm's length
transactions pursuant to which the Borrower or any of its
Subsidiaries makes payments in the ordinary course of
business upon terms no less favorable than the Borrower or
such Subsidiary, as applicable, could obtain from third
parties, none of the officers, directors, or employees of
the Borrower or any of its Subsidiaries is presently a party
to any transaction with the Borrower or any of its
Subsidiaries (other than for services as employees, officers
and directors), including any contract, agreement or other
arrangement providing for the furnishing of services to or
by, providing for rental of real or personal property to or
from, or otherwise requiring payments to or from any
officer, director or such employee or, to the knowledge of
the Borrower, any corporation, partnership, trust or other
entity, in which any officer, director, or any such employee
has a substantial interest or is an officer, director,
trustee or partner.

            Section 8.16.  Compliance with ERISA.   The Borrower
has satisfied the minimum funding standards under ERISA with
respect to its plans and is in compliance in all material
respects with the presently applicable provisions of ERISA.

            Section 8.17.  Regulations U and X.  

            No portion of any Loan is to be used, and no portion of
any Letter of Credit is to be obtained, for the purpose of
purchasing or carrying any "margin security" or "margin
stock" as such terms are used in Regulations U and X of the
Board of Governors of the Federal Reserve System, 12 C.F.R.
Parts 221 and 224.

            Section 8.18.  Subsidiaries, etc.       

Attached hereto as Schedule 8.18 is a statement showing the
names of all the Subsidiaries of the Borrower as of the
Closing Date, the amount of the capital stock of each and
the amount thereof owned by the Borrower, and the business
of each. All shares of each such Subsidiary owned by the
Borrower have been duly and validly issued and are fully
paid and nonassessable, are free and clear of all liens
other than Permitted Liens and there are no outstanding
options, warrants or other rights to purchase or securities
convertible into or exchangeable for shares of capital stock
of any such Subsidiary.

            Section 8.19.  Year 2000 Problem.       

The Borrower and its Subsidiaries have reviewed the areas
within their businesses and operations which could be
adversely affected by, and have developed or are developing
a program to address on a timely basis, the "Year 2000
Problem" (i.e. the risk that computer applications used by
the Borrower or any of its Subsidiaries may be unable to
recognize and perform properly date-sensitive functions
involving certain dates prior to and any date after December
31, 1999).  Based upon such review, the Borrower reasonably
believes that the "Year 2000 Problem" will not have any
materially adverse effect on the business or financial
condition of the Borrower and its Subsidiaries, taken as a
whole.

            Section 8.20.  Disclosure.    

The written information provided by the Borrower to the
Administrative Agent or the Banks pursuant to the Loan
Documents does not contain any untrue statement of a
material fact or omit to state a material fact necessary in
order to make the statements herein or therein, in light of
the circumstances under which they were made, not
misleading.  There is no fact known to the Borrower which
materially adversely affects, or which is reasonably likely
in the future to materially adversely affect, the business,
assets or financial condition of the Borrower and its
Subsidiaries taken as a whole, exclusive of effects
resulting from changes in general economic conditions, legal
standards or regulatory conditions.

            Section 8.21.  Collateral Bonds; Mortgages.  

                 (a)  The Collateral Bonds pledged to the
            Administrative Agent on behalf of the Banks are the
            valid and binding legal obligations of the Borrower,
            entitled in all respects to the security of the
            Mortgage.

                 (b)  The transfer and registration requirements
            for assigning all security interest in the Collateral
            Bonds to the Administrative Agent have been met.

                 (c)  There is currently no default under either
            the Mortgage or the General and Refunding Mortgage
            Indenture, and no default under, or conflict with, such
            agreements will be caused by execution of the Loan
            Documents.

                 (d)  True and correct copies of the Mortgage and
            the General and Refunding Mortgage Indenture, each as
            amended and supplemented as of the Closing Date, have
            been provided to the Banks.

                 (e)  No further action is necessary for the
            Administrative Agent s lien on the Collateral Bonds to
            be effective, and no further action is either necessary
            or desirable in order for such lien to inure to the
            benefit of the Administrative Agent on behalf of the
            Banks.

                 (f)  On or before each December 1, the Borrower
            shall deliver to the Administrative Agent a copy of the
            legal opinion required under the Mortgage.

                 (g)  The Collateral Bonds have been properly
            endorsed and certificated by the trustee and reissued
            in the name of the Administrative Agent.

                 (h)  All parties entitled to notice under the
            Mortgage or the General and Refunding Mortgage
            Indenture of the pledge of the Collateral Bonds, the
            execution and delivery of the Supplemental Indenture
            and the amendment of the Collateral Bonds have received
            proper notice (as defined in such mortgage), or have
            validly waived such notice.

                 (i)  No consents of third parties other than those
            obtained are necessary to grant the Administrative
            Agent the rights contemplated under the Pledge
            Agreement or to pledge the Collateral Bonds, execute
            and deliver the Supplemental Indenture or amend the
            Collateral Bonds.

                 Section 9.  AFFIRMATIVE COVENANTS OF THE BORROWER. 

            The Borrower covenants and agrees that, so long as any
Loan, Unpaid Reimbursement Obligation, Letter of Credit or
Note is outstanding or any Bank has any obligation to make
any Loans or the Administrative Agent has any obligation to
issue, extend or renew any Letters of Credit:

            Section 9.1.  Punctual Payment.
  The Borrower will duly and punctually pay or cause to be paid the principal
and interest on the Loans, all Reimbursement Obligations,
the Letter of Credit Fees, the commitment fees, the
Administrative Agent's fee and all other amounts provided
for in this Credit Agreement and the other Loan Documents to
which the Borrower is a party, all in accordance with the
terms of this Credit Agreement and such other Loan
Documents.

            Section 9.2.  Maintenance of Office.    

The Borrower will maintain its chief executive office at 33
State Street, Bangor, Maine 04401, or at such other place in
the United States of America as the Borrower shall designate
upon written notice to the Administrative Agent, where
notices, presentations and demands to or upon the Borrower
in respect of the Loan Documents to which the Borrower is a
party may be given or made.

            Section 9.3.  Records and Accounts.  

            The Borrower will (i) keep, and cause each of its
Subsidiaries to keep, true and accurate records and books of
account in which full, true and correct entries will be made
in accordance with GAAP, (ii) maintain adequate accounts and
reserves for all taxes (including income taxes),
depreciation, depletion, obsolescence and amortization of
its properties and the properties of its Subsidiaries, and
all other proper reserves, and (iii) at all times engage
Coopers & Lybrand or other independent certified public
accountants of nationally recognized standing reasonably
satisfactory to the Administrative Agent as the independent
certified public accountants of the Borrower and its
Subsidiaries and will not permit more than thirty (30) days
to elapse between the cessation of such firm's (or any
successor firm's) engagement as the independent certified
public accountants of the Borrower and its Subsidiaries and
the appointment in such capacity of a successor firm as
shall be satisfactory to the Administrative Agent.

            Section 9.4.  Financial Statements, Certificates and
Information.     

The Borrower will deliver to each of the Banks:

                 (a)  as soon as practicable, but in any event not
            later than one-hundred (100) days after the end of each
            fiscal year of the Borrower, the consolidated balance
            sheet of the Borrower and its Subsidiaries as at the
            end of such year, and the related consolidated
            statements of cash flows, operations and retained

license from any officer, agency or instrumentality of any
government shall become necessary or required in order that

            the other Loan Documents, when the same shall become
            due and payable, whether at the stated date of maturity
            or any accelerated date of maturity or at any other
            date fixed for payment within three (3) days after the
            same shall become due and payable;

            Capitalized Leases in excess of $500,000 for such
            period of time as would permit (assuming the giving of
            appropriate notice if required) the holder or holders
            thereof or of any obligations issued thereunder to
            accelerate the maturity thereof;

                 (g)  the Borrower or any of its Subsidiaries shall
            make an assignment for the benefit of creditors, or
            admit in writing its inability to pay or generally fail
            to pay its debts as they mature or become due, or shall
            petition or apply for the appointment of a trustee or
            other custodian, liquidator or receiver of the Borrower
            or any of its Subsidiaries or of any substantial part
            of the assets of the Borrower or any of its

            jurisdiction, now or hereafter in effect, or shall take
            any action to authorize or in furtherance of any of the
            foregoing, or if any such petition or application shall
            be filed or any such case or other proceeding shall be
            commenced against the Borrower or any of its
            Subsidiaries and the Borrower or any of its
            Subsidiaries shall indicate its approval thereof,
            consent thereto or acquiescence therein or such
            petition or application shall not have been dismissed

            constituted;

                 (i)  there shall remain in force, undischarged,
            unsatisfied and unstayed for more than sixty (60) days,
            any final unpaid judgment (from which all appeals have
            been taken and determined or as to which all time for
            appeals has lapsed) against the Borrower or any of its
            Subsidiaries which, with other outstanding final
            judgments shall continue unsatisfied and in effect,
            (net of uncontested insurance coverage) against the

            repurchased in whole or in part;

                 (k)  if any of the Loan Documents shall be
            cancelled, terminated, revoked or rescinded or the
            Administrative Agent's security interests, mortgages or
            liens in a substantial portion of the Collateral Bonds
            shall cease to be perfected, or shall cease to have the
            priority contemplated by the Security Documents, in
            each case otherwise than in accordance with the terms

            thereof;

                 (l)  the Borrower or any ERISA Affiliate shall
            fail to pay when due an amount or amounts aggregating
            in excess of $100,000 which it shall have become liable
            to pay to the PBGC or to an Employee Benefit Plan under

            cause a trustee to be appointed to administer any such
            Employee Benefit Plan or Employee Benefit Plans or a
            proceeding shall be instituted by a fiduciary of any
            such Employee Benefit Plan or Employee Benefit Plans to
            enforce Section  515 of ERISA and such proceeding shall
            not have been dismissed within 30 days thereafter; or a
            condition shall exist by reason of which the PBGC would
            be entitled to obtain a decree adjudicating that such
            Employee Benefit Plan or Employee Benefit Plans must be

            more than sixty (60) days; or

                 (n)  (i) a judgement creditor shall obtain

            property (the "Mortgaged Property") referred to in the
            Mortgage by any means, including, without limitation,
            levy, distraint, replevin or self-help, (ii) any
            foreclosure or other remedial action in respect of or
            affecting the Mortgaged Property shall be commenced by
            or on behalf of the holders of the Second Mortgage
            Bonds or the trustee under the General and Refunding
            Mortgage Indenture, (iii) any material portion of the
            Mortgage Property shall be taken by eminent domain or
            condemnation, (iv) the Mortgage shall cease to be in
            full force and effect or the Borrower shall disavow its
            obligations thereunder or shall contest the validity or
            enforceability thereof, (v) the trustee under the
            Mortgage (the "First Mortgage Trustee") shall cease, in
            respect of any material portion of the Mortgaged
            Property, to have a valid and perfected first priority
            security interest therein, (vi) the security interest
            of the First Mortgage Trustee in any material portion
            of the Mortgaged Property shall otherwise become
            impaired or unenforceable, or (vii) any provision of
            the Mortgage, the Supplemental Indenture or the
            Collateral Bonds shall be amended, supplemented, waived
            or otherwise modified in any respect except to the
            extent expressly permitted by the Pledge Agreement.

then, and in any such event, so long as the same may be
continuing, the Administrative Agent may, and upon the
request of the Majority Banks shall, by notice in writing to
the Borrower declare all amounts owing with respect to this
Credit Agreement, the Notes and the other Loan Documents and
all Reimbursement Obligations to be, and they shall
thereupon forthwith become, immediately due and payable
without presentment, demand, protest or other notice of any
kind, all of which are hereby expressly waived by the
Borrower; provided that in the event of any Event of Default
specified in Section Section 14.1(g), 14.1(h) or 14.1(j),
all such amounts shall become immediately due and payable
automatically and without any requirement of notice from the
Administrative Agent or any Bank.

            Section 14.2.  Termination of Commitments.  

            If any one or more of the Events of Default specified
in Section 14.1(g), Section 14.1(h) or Section 14.1(j) shall
occur, any unused portion of the credit hereunder shall
forthwith terminate and each of the Banks shall be relieved
of all further obligations to make Loans to the Borrower and
the Administrative Agent shall be relieved of all further
obligations to issue, extend or renew Letters of Credit.  If
any other Event of Default shall have occurred and be
continuing, the Administrative Agent may and, upon the
request of the Majority Banks, shall, by notice to the
Borrower, terminate the unused portion of the credit
hereunder, and upon such notice being given such unused
portion of the credit hereunder shall terminate immediately
and each of the Banks shall be relieved of all further
obligations to make Loans and the Administrative Agent shall
be relieved of all further obligations to issue, extend or
renew Letters of Credit.  No termination of the credit
hereunder shall relieve the Borrower of any of the
Obligations.

            Section 14.3.  Remedies.

            In case any one or more of the Events of Default shall
have occurred and be continuing, and whether or not the
Banks shall have accelerated the maturity of the Loans
pursuant to Section 14.1, each Bank, if owed any amount with
respect to the Loans or the Reimbursement Obligations, may,
with the consent of the Majority Banks but not otherwise,
proceed to protect and enforce its rights by suit in equity,
action at law or other appropriate proceeding, whether for
the specific performance of any covenant or agreement
contained in this Credit Agreement and the other Loan
Documents or any instrument pursuant to which the
Obligations to such Bank are evidenced, including as
permitted by applicable law the obtaining of the ex parte
appointment of a receiver, and, if such amount shall have
become due, by declaration or otherwise, proceed to enforce
the payment thereof or any other legal or equitable right of
such Bank.  No remedy herein conferred upon any Bank or the
Administrative Agent or the holder of any Note or purchaser
of any Letter of Credit Participation is intended to be
exclusive of any other remedy and each and every remedy
shall be cumulative and shall be in addition to every other
remedy given hereunder or now or hereafter existing at law
or in equity or by statute or any other provision of law.

            Section 14.4.  Distribution of Collateral Bonds
Proceeds.   

In the event that, following the occurrence or during the
continuance of any Event of Default, the Administrative
Agent or any Bank, as the case may be, receives any monies
in connection with the enforcement of any the Security
Documents, or otherwise with respect to the realization upon
any of the Collateral Bonds, such monies shall be
distributed for application as follows:

                 (a)  First, to the payment of, or (as the case may
            be) the reimbursement of the Administrative Agent for
            or in respect of all reasonable costs, expenses,
            disbursements and losses which shall have been incurred
            or sustained by the Administrative Agent in connection
            with the collection of such monies by the
            Administrative Agent, for the exercise, protection or
            enforcement by the Administrative Agent of all or any
            of the rights, remedies, powers and privileges of the
            Administrative Agent and the Banks under this Credit
            Agreement or any of the other Loan Documents or in
            respect of the Collateral Bonds or in support of any
            provision of adequate indemnity to the Administrative
            Agent against any taxes or liens which by law shall
            have, or may have, priority over the rights of the
            Administrative Agent to such monies;

                 (b)  Second, to all other Obligations then due and
            payable to be shared pro rata among the Banks in
            accordance with their respective Commitment Percentages
            and Term Loan Percentages; provided, however, that
            distributions shall be made (A) pari passu among
            Obligations with respect to the Agent's fee payable
            pursuant to Section 6.1 and all other Obligations and
            (B) with respect to each type of Obligation owing to
            the Banks, such as interest, principal, fees and
            expenses, among the Banks pro rata;

                 (c)  Third, upon payment and satisfaction in full
            or other provisions for payment in full satisfactory to
            the Banks and the Administrative Agent of all of the
            Obligations, to the payment of any obligations required
            to be paid pursuant to Section 9-504(1)(c) of the
            Uniform Commercial Code of the State of New York; and

                 (d)  Fourth, the excess, if any, shall be returned
            to the Borrower or to such other Persons as are
            entitled thereto.

                      Section 15.  SETOFF.

            Regardless of the adequacy of any collateral, during
the continuance of any Event of Default, any deposits or
other sums credited by or due from any of the Banks to the
Borrower and any securities or other property of the
Borrower in the possession of such Bank may be applied to or
set off by such Bank against the payment of Obligations then
due and payable of the Borrower to such Bank.  Each of the
Banks agrees with each other Bank that if such Bank shall
receive from the Borrower, whether by voluntary payment,
exercise of the right of setoff, counterclaim, cross action,
enforcement of the claim evidenced by the Notes held by, or
constituting Reimbursement Obligations owed to, such Bank by
proceedings against the Borrower at law or in equity or by
proof thereof in bankruptcy, reorganization, liquidation,
receivership or similar proceedings, or otherwise, and shall
retain and apply to the payment of the Note or Notes held
by, or Reimbursement Obligations owed to, such Bank any
amount in excess of its ratable portion of the payments
received by all of the Banks with respect to the Notes held
by, and Reimbursement Obligations owed to, all of the Banks,
such Bank will make such disposition and arrangements with
the other Banks with respect to such excess, either by way
of distribution, pro tanto assignment of claims, subrogation
or otherwise as shall result in each Bank receiving in
respect of the Notes held by it or Reimbursement Obligations
owed it, its proportionate payment as contemplated by this
Credit Agreement; provided that if all or any part of such
excess payment is thereafter recovered from such Bank, such
disposition and arrangements shall be rescinded and the
amount restored to the extent of such recovery, but without
interest.  Such Bank shall notify the Borrower and the Agent
and the other Banks promptly after exercising any right of
setoff.

                      Section 16.  THE AGENTS.

            Section 16.1.  Authorization.  

                 (a)  The Administrative Agent is authorized to
            take such action on behalf of each of the Banks and to
            exercise all such powers as are hereunder and under any
            of the other Loan Documents and any related documents
            delegated to the Administrative Agent, together with
            such powers as are reasonably incident thereto,
            provided that no duties or responsibilities not
            expressly assumed herein or therein shall be implied to
            have been assumed by the Administrative Agent.

                 (b)  The relationship between the Administrative
            Agent and each of the Banks is that of an independent
            contractor.  The use of the term "Administrative Agent"
            is for convenience only and is used to describe, as a
            form of convention, the independent contractual
            relationship between the Administrative Agent and each
            of the Banks.  Nothing contained in this Credit
            Agreement nor the other Loan Documents shall be
            construed to create an agency, trust or other fiduciary
            relationship between the Administrative Agent and any
            of the Banks.

                 (c)  As an independent contractor empowered by the
            Banks to exercise certain rights and perform certain
            duties and responsibilities hereunder and under the
            other Loan Documents, the Administrative Agent is
            nevertheless a "representative" of the Banks, as that
            term is defined in Article 1 of the Uniform Commercial
            Code, for purposes of actions for the benefit of the
            Banks and the Administrative Agent with respect to all
            collateral security and guaranties contemplated by the
            Loan Documents.  Such actions include the designation
            of the Administrative Agent as "secured party",
            "mortgagee" or the like on all financing statements and
            other documents and instruments, whether recorded or
            otherwise, relating to the attachment, perfection,
            priority or enforcement of any security interests,
            mortgages or deeds of trust in collateral security
            intended to secure the payment or performance of any of
            the Obligations, all for the benefit of the Banks and
            the Administrative Agent.

                 (d)  The Documentation Agent shall not have any
            right, power, obligation, liability, responsibility or
            duty under this Credit Agreement in such capacity,
            other than those applicable to all Banks as Banks.

            Section 16.2.  Employees and Agents.

The Administrative Agent may exercise its powers and execute
its duties by or through employees or agents and shall be
entitled to take, and to rely on, advice of counsel
concerning all matters pertaining to its rights and duties
under this Credit Agreement and the other Loan Documents.

            Section 16.3.  No Liability.       

Neither the Administrative Agent nor any of its
shareholders, directors, officers or employees nor any other
Person assisting them in their duties nor any Administrative
Agent or employee thereof, shall be liable for any waiver,
consent or approval given or any action taken, or omitted to
be taken, in good faith by it or them hereunder or under any
of the other Loan Documents, or in connection herewith or
therewith, or be responsible for the consequences of any
oversight or error of judgment whatsoever, except that the
Administrative Agent or such other Person, as the case may
be, may be liable for losses due to its willful misconduct
or gross negligence.

            Section 16.4.  No Representations.  The Administrative
Agent shall not be responsible for the execution or validity
or enforceability of this Credit Agreement, the Notes, the
Letters of Credit, any of the other Loan Documents or any
instrument at any time constituting, or intended to
constitute, collateral security for the Notes, or for the
value of any such collateral security or for the validity,
enforceability or collectability of any such amounts owing
with respect to the Notes, or for any recitals or
statements, warranties or representations made herein or in
any of the other Loan Documents or in any certificate or
instrument hereafter furnished to it by or on behalf of the
Borrower, or be bound to ascertain or inquire as to the
performance or observance of any of the terms, conditions,
covenants or agreements herein or in any instrument at any
time constituting, or intended to constitute, collateral
security for the Notes or to inspect any of the properties,
books or records of the Borrower or any of its Subsidiaries. 
The Administrative Agent shall not be bound to ascertain
whether any notice, consent, waiver or request delivered to
it by the Borrower or any holder of any of the Notes shall
have been duly authorized or is true, accurate and complete. 
The Administrative Agent has not made nor does it now make
any representations or warranties, express or implied, nor
does it assume any liability to the Banks, with respect to
the credit worthiness or financial conditions of the
Borrower or any of its Subsidiaries.  Each Bank acknowledges
that it has, independently and without reliance upon the
Administrative Agent or any other Bank, and based upon such
information and documents as it has deemed appropriate, made
its own credit analysis and decision to enter into this
Credit Agreement.

            Section 16.5.  Payments.  

                 Section 16.5.1.  Payments to Administrative
            Agent.  

                 A payment by the Borrower to the Administrative
            Agent hereunder or any of the other Loan Documents for
            the account of any Bank shall constitute a payment to
            such Bank.  The Administrative Agent agrees promptly to
            distribute to each Bank such Bank's pro rata share of
            payments received by the Administrative Agent for the
            account of the Banks except as otherwise expressly
            provided herein or in any of the other Loan Documents.

                 Section 16.5.2.  Distribution by Administrative
            Agent.         

If in the opinion of the Administrative Agent the
distribution of any amount received by it in such capacity
hereunder, under the Notes or under any of the other Loan
Documents might involve it in liability, it may refrain from
making distribution until its right to make distribution
shall have been adjudicated by a court of competent
jurisdiction.  If a court of competent jurisdiction shall
adjudge that any amount received and distributed by the
Administrative Agent is to be repaid, each Person to whom
any such distribution shall have been made shall either
repay to the Administrative Agent its proportionate share of
the amount so adjudged to be repaid or shall pay over the
same in such manner and to such Persons as shall be
determined by such court.

                 Section 16.5.3.  Delinquent Banks.  

                 Notwithstanding anything to the contrary contained
            in this Credit Agreement or any of the other Loan
            Documents, any Bank that fails (i) to make available to
            the Administrative Agent its pro rata share of any Loan
            or to purchase any Letter of Credit Participation or
            (ii) to comply with the provisions of Section 15 with
            respect to making dispositions and arrangements with
            the other Banks, where such Bank's share of any payment
            received, whether by setoff or otherwise, is in excess
            of its pro rata share of such payments due and payable
            to all of the Banks, in each case as, when and to the
            full extent required by the provisions of this Credit
            Agreement, shall be deemed delinquent (a "Delinquent
            Bank") and shall be deemed a Delinquent Bank until such
            time as such delinquency is satisfied.  A Delinquent
            Bank shall be deemed to have assigned any and all
            payments due to it from the Borrower, whether on
            account of outstanding Loans, interest, fees or
            otherwise, to the remaining nondelinquent Banks for
            application to, and reduction of, their respective pro
            rata shares of all outstanding Loans and Unpaid
            Reimbursement Obligations.  The Delinquent Bank hereby
            authorizes the Administrative Agent to distribute such
            payments to the nondelinquent Banks in proportion to
            their respective pro rata shares of all outstanding
            Loans and Unpaid Reimbursement Obligations.  A
            Delinquent Bank shall be deemed to have satisfied in
            full a delinquency when and if, as a result of
            application of the assigned payments to all outstanding
            Loans and Unpaid Reimbursement Obligations of the
            nondelinquent Banks, the Banks' respective pro rata
            shares of all outstanding Loans and Unpaid
            Reimbursement Obligations and have returned to those in
            effect immediately prior to such delinquency and
            without giving effect to the nonpayment causing such
            delinquency.

            Section 16.6.  Holders of Notes.   

The Administrative Agent may deem and treat the payee of any
Note or the purchaser of any Letter of Credit Participation
as the absolute owner or purchaser thereof for all purposes
hereof until it shall have been furnished in writing with a
different name by such payee or by a subsequent holder,
assignee or transferee.

            Section 16.7.  Indemnity.     

The Banks ratably agree hereby to indemnify and hold
harmless the Administrative Agent and its affiliates from
and against any and all claims, actions and suits (whether
groundless or otherwise), losses, damages, costs, expenses
(including any expenses for which the Administrative Agent
or such affiliate has not been reimbursed by the Borrower as
required by Section 17), and liabilities of every nature and
character arising out of or related to this Credit
Agreement, the Notes, or any of the other Loan Documents or
the transactions contemplated or evidenced hereby or
thereby, or the Administrative Agent's actions taken
hereunder or thereunder, except to the extent that any of
the same shall be directly caused by the Administrative
Agent's willful misconduct or gross negligence.

            Section 16.8.  Administrative Agent as Bank.      

In its individual capacity, BKB shall have the same
obligations and the same rights, powers and privileges in
respect to its Commitment and the Loans made by it, and as
the holder of any of the Notes and as the purchaser of any
Letter of Credit Participations, as it would have were it
not also the Administrative Agent.

            Section 16.9.  Resignation.  

            The Administrative Agent may resign at any time by
giving sixty (60) days prior written notice thereof to the
Banks and the Borrower.  Upon any such resignation, the
Majority Banks shall have the right to appoint a successor
Administrative Agent.  Unless an Event of Default shall have
occurred and be continuing, such successor Administrative
Agent shall be reasonably acceptable to the Borrower.  If no
successor Administrative Agent shall have been so appointed
by the Majority Banks and approved by the Borrower and shall
have accepted such appointment within thirty (30) days after
the retiring Administrative Agent's giving of notice of
resignation, then the retiring Administrative Agent may, on
behalf of the Banks, appoint a successor Administrative
Agent, which shall be a financial institution having a
rating of not less than A or its equivalent by S&P.  Upon
the acceptance of any appointment as Administrative Agent
hereunder by a successor Administrative Agent, such
successor Administrative Agent shall thereupon succeed to
and become vested with all the rights, powers, privileges
and duties of the retiring Administrative Agent, and the
retiring Administrative Agent shall be discharged from its
duties and obligations hereunder.  After any retiring
Administrative Agent's resignation, the provisions of this
Credit Agreement and the other Loan Documents shall continue
in effect for its benefit in respect of any actions taken or
omitted to be taken by it while it was acting as
Administrative Agent.

            Section 16.10.  Notification of Defaults and Events of
Default.    

Each Bank hereby agrees that, upon learning of the existence
of a Default or an Event of Default, it shall promptly
notify the Administrative Agent thereof.  The Administrative
Agent hereby agrees that upon receipt of any notice under
this Section 16.10 it shall promptly notify the other Banks
of the existence of such Default or Event of Default.

            Section 16.11.  Duties in the Case of
Enforcement.     

In case one of more Events of Default have occurred and
shall be continuing, and whether or not acceleration of the
Obligations shall have occurred, the Administrative Agent
shall, if (i) so requested by the Majority Banks and (ii)
the Banks have provided to the Administrative Agent such
additional indemnities and assurances against expenses and
liabilities as the Administrative Agent may reasonably
request, proceed to enforce the provisions of the Security
Documents authorizing the sale or other disposition of all
or any part of the Collateral Bonds and exercise all or any
such other legal and equitable and other rights or remedies
as it may have in respect of such Collateral Bonds.  The
Majority Banks may direct the Administrative Agent in
writing as to the method and the extent of any such sale or
other disposition, the Banks hereby agreeing to indemnify
and hold the Administrative Agent, harmless from all
liabilities incurred in respect of all actions taken or
omitted in accordance with such directions, provided that
the Administrative Agent need not comply with any such
direction to the extent that the Administrative Agent
reasonably believes the Administrative Agent's compliance
with such direction to be unlawful or commercially
unreasonable in any applicable jurisdiction.

                 Section 17.  EXPENSES AND INDEMNIFICATION.

            Section 17.1.  Expenses.

The Borrower agrees to pay (i) the reasonable costs of

Loan Documents and the other agreements and instruments
mentioned herein, (ii) any taxes payable by the
Administrative Agent or any of the Banks on or with respect

accordance with Section 6.2.2 (the Borrower hereby agreeing
to indemnify the Administrative Agent and each Bank with
respect thereto), (iii) the reasonable fees, expenses and
disbursements of the Administrative Agent's Special Counsel
or any local counsel to the Administrative Agent incurred in
connection with the preparation, syndication, administration
or interpretation of the Loan Documents and other
instruments mentioned herein, each closing hereunder, any
amendments, modifications, approvals, consents or waivers
hereto or hereunder, or the cancellation of any Loan
Document upon payment in full in cash of all of the
Obligations or pursuant to any terms of such Loan Document
for providing for such cancellation, (iv) the reasonable
out-of-pocket fees, expenses and disbursements of the
Administrative Agent or any of its affiliates incurred by
the Administrative Agent or such affiliate in connection
with the preparation, syndication, administration or
interpretation of the Loan Documents and other instruments
mentioned herein, (v) any reasonable out-of-pocket fees,
costs, expenses and bank charges, including bank charges for
returned checks, incurred by the Administrative Agent in
establishing, maintaining or handling agency accounts, lock
box accounts and other accounts for the collection of any of
the Collateral Bonds or the stock of Bangor Energy Resale,
Inc.; and (vi) all reasonable out-of-pocket expenses
(including without limitation reasonable attorneys' fees and
costs, and reasonable consulting, accounting, appraisal,
investment banking and similar professional fees and
charges) incurred by any Bank or the Administrative Agent in
connection with (A) the enforcement of or preservation of
rights under any of the Loan Documents against the Borrower
or the administration thereof after the occurrence of a
Default or Event of Default and (B) any litigation,
proceeding or dispute whether arising hereunder or
otherwise, in any way related to any Bank's or the
Administrative Agent's relationship with the Borrower
hereunder.  Notwithstanding the foregoing, the Borrower
shall have no obligation hereunder to the Administrative
Agent or any Bank with respect to any costs or expenses
arising from the gross negligence or willful misconduct of
the Administrative Agent or such Bank, as the case may be.

            Section 17.2.  Indemnification.    

The Borrower agrees to indemnify and hold harmless the
Administrative Agent, the Documentation Agent, the Co-
Arrangers, their affiliates and the Banks from and against
any and all liabilities, losses, damages and expense of
every nature and character resulting from any and all
claims, actions and suits whether groundless or otherwise,
arising out of this Credit Agreement or any of the other
Loan Documents or the transactions contemplated hereby
including, without limitation, (i) any actual or proposed
use by the Borrower of the proceeds of any of the Loans or
Letters of Credit, (ii) the Borrower entering into or
performing this Credit Agreement or any of the other Loan
Documents or (iii) with respect to the Borrower and its
Subsidiaries and their respective properties and assets, the
violation of any Environmental Law, the presence, disposal,
escape, seepage, leakage, spillage, discharge, emission,
release or threatened release of any Hazardous Substances or
any action, suit, proceeding or investigation brought or
threatened with respect to any Hazardous Substances
(including, but not limited to, claims with respect to
wrongful death, personal injury or damage to property), in
each case including, without limitation, the reasonable fees
and disbursements of counsel incurred in connection with any
such investigation, litigation or other proceeding except
for the gross negligence or willful misconduct of the party
indemnified.  In litigation, or the preparation therefor,
the Banks and the Administrative Agent and its affiliates
shall be entitled to select their own counsel and, in
addition to the foregoing indemnity, the Borrower agrees to
pay promptly the reasonable fees and expenses of such
counsel.  Notwithstanding anything to the contrary herein,
the Borrower shall not be responsible for (i) the cost of
more than one counsel for the Administrative Agent and its
affiliates, and any Bank (that is not the Administrative
Agent) and its affiliates, respectively, or (ii)
settlements, waivers or releases made without Borrower s
consent.  If, and to the extent that the obligations of the
Borrower under this Section 17.2 are unenforceable for any
reason, the Borrower hereby agrees to make the maximum
contribution to the payment in satisfaction of such
obligations which is permissible under applicable law.

            Section 17.3.  Survival.      

The covenants contained in this Section 17 shall survive
payment or satisfaction in full of all other Obligations.

                 Section 18.  SURVIVAL OF COVENANTS, ETC.

            All covenants, agreements, representations and
warranties made herein, in the Notes, in any of the other
Loan Documents or in any documents or other papers delivered
by or on behalf of the Borrower or any of its Subsidiaries
pursuant hereto shall be deemed to have been relied upon by
the Banks and the Administrative Agent, notwithstanding any
investigation heretofore or hereafter made by any of them,
and shall survive the making by the Banks of any of the
Loans and the issuance, extension or renewal of any Letters
of Credit, as herein contemplated, and shall continue in
full force and effect so long as any Letter of Credit or any
amount due under this Credit Agreement or the Notes or any
of the other Loan Documents remains outstanding or any Bank
has any obligation to make any Loans or the Administrative
Agent has any obligation to issue, extend or renew any
Letter of Credit, and for such further time as may be
otherwise expressly specified in this Credit Agreement.  All
statements contained in any certificate or other paper
delivered to any Bank or the Administrative Agent at any
time by or on behalf of the Borrower or any of its
Subsidiaries pursuant hereto or in connection with the
transactions contemplated hereby shall constitute
representations and warranties by the Borrower hereunder.

                 Section 19.  ASSIGNMENT AND PARTICIPATION. 

            Section 19.1.  Conditions to Assignment by Banks. 

            Except as provided herein, each Bank may assign to one
or more Eligible Assignees all or a portion of its
interests, rights and obligations under this Credit
Agreement (including all or a portion of its Commitment
Percentage and Commitment and/or its Term Loan Percentage
and Term Loan Exposure, and the same portion of the Loans at
the time owing to it and the Notes held by it and, if
applicable, its participating interest in the risk relating

given its prior written consent to such assignment, which
consent will not be unreasonably withheld, (ii) each such
assignment shall be of a constant, and not a varying,
percentage of all the assigning Bank's rights and
obligations under this Credit Agreement, (iii) each
assignment shall be in a minimum amount of $5,000,000 or, if
a Bank s total Commitment and/or Term Loan Exposure is less
than $5,000,000, in a minimum amount equal to such Bank s
total Commitment and/or Term Loan Exposure, (iv) the parties
to such assignment shall execute and deliver to the
Administrative Agent, for recording in the Register (as
hereinafter defined), an Assignment and Acceptance,
substantially in the form of Exhibit E hereto (an
"Assignment and Acceptance"), together with any  Notes
subject to such assignment, (v) so long as no Event of
Default exists, the Administrative Agent and the
Documentation Agent (or their affiliates) shall retain, free
of any such assignment, an amount of not less than
$5,000,000, and (vi) any Bank may at any time, and from time
to time, assign to any branch, lending office, affiliate of
such Bank or Related Fund all or any part of its rights and

thereunder shall be a party hereto and, to the extent
provided in such Assignment and Acceptance, have the rights
and obligations of a Bank hereunder, and (ii) the assigning
Bank shall, to the extent provided in such assignment and
upon payment to the Administrative Agent of the registration
fee referred to in Section 19.3, be released from its
obligations under this Credit Agreement.

            Section 19.2.  Certain Representations and Warranties;
Limitations; Covenants.    

By executing and delivering an Assignment and Acceptance,
the parties to the assignment thereunder confirm to and
agree with each other and the other parties hereto as
follows:

                 (a)  other than the representation and warranty
            that it is the legal and beneficial owner of the
            interest being assigned thereby free and clear of any
            adverse claim, the assigning Bank makes no
            representation or warranty, express or implied, and
            assumes no responsibility with respect to any
            statements, warranties or representations made in or in
            connection with this Credit Agreement or the execution,
            legality, validity, enforceability, genuineness,
            sufficiency or value of this Credit Agreement, the
            other Loan Documents or any other instrument or
            document furnished pursuant hereto or the attachment,
            perfection or priority of any security interest or
            mortgage,

                 (b)  the assigning Bank makes no representation or
            warranty and assumes no responsibility with respect to
            the financial condition of the Borrower and its
            Subsidiaries or any other Person primarily or
            secondarily liable in respect of any of the
            Obligations, or the performance or observance by the
            Borrower or any other Person primarily or secondarily
            liable in respect of any of the Obligations of any of
            their obligations under this Credit Agreement or any of
            the other Loan Documents or any other instrument or
            document furnished pursuant hereto or thereto;

                 (c)  such assignee confirms that it has received a
            copy of this Credit Agreement, together with copies of
            the most recent financial statements referred to in
            Section 8.4 and Section 9.4 and such other documents
            and information as it has deemed appropriate to make
            its own credit analysis and decision to enter into such
            Assignment and Acceptance;

                 (d)  such assignee will, independently and without
            reliance upon the assigning Bank, the Administrative
            Agent or any other Bank and based on such documents and
            information as it shall deem appropriate at the time,
            continue to make its own credit decisions in taking or
            not taking action under this Credit Agreement;

                 (e)  such assignee represents and warrants that it
            is an Eligible Assignee;

                 (f)  such assignee appoints and authorizes the
            Administrative Agent to take such action as
            Administrative Agent on its behalf and to exercise such
            powers under this Credit Agreement and the other Loan
            Documents as are delegated to the Administrative Agent
            by the terms hereof or thereof, together with such
            powers as are reasonably incidental thereto;

                 (g)  such assignee agrees that it will perform in
            accordance with their terms all of the obligations that
            by the terms of this Credit Agreement are required to
            be performed by it as a Bank;

                 (h)  such assignee represents and warrants that it
            is legally authorized to enter into such Assignment and
            Acceptance;

                 (i)  if applicable, such assignee acknowledges
            that it has made arrangements with the assigning Bank
            satisfactory to such assignee with respect to its pro
            rata share of Letter of Credit Fees in respect of
            outstanding Letters of Credit; and

                 (j)  if such assignee is not incorporated or
            organized under the laws of the United States of
            America or a state thereof or the District of Columbia
            (a "Non-U.S. Bank"), such assignee agrees that it will
            deliver to the Borrower and the Administrative Agent
            two duly completed copies of United States Internal
            Revenue Service Form 1001 or 4224 or successor
            applicable form, as the case may be, certifying in each
            case that such Non-U.S. Bank is entitled to receive
            payments under this Agreement and the Notes payable to
            it, without deduction or withholding of any United
            States federal income taxes.  Each Non-U.S. Bank that
            so delivers a Form 1001 or 4224 pursuant to the
            preceding sentence further undertakes to deliver to
            each of the Borrower and the Administrative Agent two
            further copies of Form 1001 or 4224 or successor
            applicable form, or other manner of certification, as
            the case may be, on or before the date that any such
            letter or form expires or becomes obsolete or after the
            occurrence of any event requiring a change in the most
            recent form previously delivered by it to the Borrower,
            and such extensions or renewals thereof as may
            reasonably be requested by the Borrower, certifying in
            the case of a Form 1001 or 4224 that such Non-U.S. Bank
            is entitled to receive payments under this Agreement
            and the Notes without deduction or withholding of any
            United States federal income taxes, unless in any such
            case an event (including, without limitation, any
            change in treaty, law or regulation) has occurred prior
            to the date on which any such delivery would otherwise
            be required which renders all such forms inapplicable
            or which would prevent such Non-U.S. Bank from duly
            completing and delivering any such form with respect to
            it and such Non-U.S. Bank advises the Borrower that it
            is not capable of receiving payments without any
            deduction or withholding of United States federal
            income tax.

            Section 19.3.  Register.      

The Administrative Agent shall maintain a copy of each
Assignment and Acceptance delivered to it and a register or
similar list (the "Register") for the recordation of the
names and addresses of the Banks and the Commitment
Percentage of, and principal amount of the Term Loan and the
Revolving Credit Loans owing to and Letter of Credit
Participations purchased by, the Banks from time to time.
The entries in the Register shall be conclusive, in the
absence of manifest error, and the Borrower, the
Administrative Agent and the Banks may treat each Person
whose name is recorded in the Register as a Bank hereunder
for all purposes of this Credit Agreement.  The Register
shall be available for inspection by the Borrower and the
Banks at any reasonable time and from time to time upon
reasonable prior notice. Upon each such recordation, the
assigning Bank agrees to pay to the Administrative Agent a
registration fee in the sum of $3,500, provided that such
registration fee shall not be required for assignments
pursuant to Section 19.1(vi).

            Section 19.4.  New Notes.     

Upon its receipt of an Assignment and Acceptance executed by
the parties to such assignment, together with each Note
subject to such assignment, the Administrative Agent shall
(i) record the information contained therein in the
Register, and (ii) give prompt notice thereof to the
Borrower and the Banks (other than the assigning Bank).
Within five (5) Business Days after receipt of such notice,
the Borrower, at its own expense, shall execute and deliver
to the Administrative Agent, in exchange for each
surrendered Note, a new Note to the order of such Eligible
Assignee in an amount equal to the amount assumed by such
Eligible Assignee pursuant to such Assignment and Acceptance
and, if the assigning Bank has retained some portion of its
obligations hereunder, a new Note to the order of the
assigning Bank in an amount equal to the amount retained by
it hereunder.  Such new Notes shall provide that they are
replacements for the surrendered Notes, shall be in an
aggregate principal amount equal to the aggregate principal
amount of the surrendered Notes, shall be dated the
effective date of such in Assignment and Acceptance and
shall otherwise be substantially the form of the assigned
Notes. The surrendered Notes shall be cancelled and returned
to the Borrower.

            Section 19.5.  Participations.     

Each Bank may sell participations to one or more banks or
other entities in all or a portion of such Bank's rights and
obligations under this Credit Agreement and the other Loan
Documents; provided that (i) each such participation shall
be in an amount of not less than $2,500,000, (ii) any such
sale or participation shall not affect the rights and duties
of the selling Bank hereunder to the Borrower, (iii) the
only rights granted to the participant pursuant to such
participation arrangements with respect to waivers,
amendments or modifications of the Loan Documents shall be
the rights to approve waivers, amendments or modifications
that would reduce the principal of or the interest rate on
any Loans, extend the term or increase the amount of the
Commitment and/or Term Loan Exposure of such Bank as it
relates to such participant, reduce the amount of any
commitment fees or Letter of Credit Fees to which such
participant is entitled or extend any regularly scheduled
payment date for principal or interest, and (iv) the
Borrower shall not be obligated to pay any such Bank any
greater amount pursuant to Section 6.2.2, Section 6.6,
Section 6.7 or Section 6.9 in respect of the amount of the
participation transferred by such transferor Bank to such
participant than had no such transfer occurred.

            Section 19.6.  Disclosure.    

The Borrower agrees that in addition to disclosures made in
accordance with standard and customary banking practices any
Bank may disclose information obtained by such Bank pursuant
to this Credit Agreement to assignees or participants and
potential assignees or participants hereunder; provided that
such assignees or participants or potential assignees or
participants shall agree (i) to treat in confidence such
information unless such information otherwise becomes public
knowledge, (ii) not to disclose such information to a third
party, except as required by law or legal process and (iii)
not to make use of such information for purposes of
transactions unrelated to such contemplated assignment or
participation.

            Section 19.7.  Assignee or Participant Affiliated with
the Borrower.  

            If any assignee Bank is an Affiliate of the Borrower,
then any such assignee Bank shall have no right to vote as a
Bank hereunder or under any of the other Loan Documents for
purposes of granting consents or waivers or for purposes of
agreeing to amendments or other modifications to any of the
Loan Documents or for purposes of making requests to the
Administrative Agent pursuant to Section 14.1 or Section
14.2, and the determination of the Majority Banks shall for
all purposes of this Credit Agreement and the other Loan
Documents be made without regard to such assignee Bank's
interest in any of the Loans or Reimbursement Obligations. 
If any Bank sells a participating interest in any of the
Loans or Reimbursement Obligations to a participant, and
such participant is the Borrower or an Affiliate of the
Borrower, then such transferor Bank shall promptly notify
the Administrative Agent of the sale of such participation. 
A transferor Bank shall have no right to vote as a Bank
hereunder or under any of the other Loan Documents for
purposes of granting consents or waivers or for purposes of
agreeing to amendments or modifications to any of the Loan
Documents or for purposes of making requests to the
Administrative Agent pursuant to Section 14.1 or Section
14.2 to the extent that such participation is beneficially
owned by the Borrower or any Affiliate of the Borrower, and
the determination of the Majority Banks shall for all
purposes of this Credit Agreement and the other Loan
Documents be made without regard to the interest of such

Any assigning Bank shall retain its rights to be indemnified

of the twelve Federal Reserve Banks organized under Section
4 of the Federal Reserve Act, 12 U.S.C. Section 341.  No

the Administrative Agent agrees, on behalf of itself and
each of its affiliates, directors, officers, employees and
representatives, to use reasonable precautions to keep
confidential, in accordance with their customary procedures
for handling confidential information of the same nature and
in accordance with safe and sound banking practices, any
non-public information supplied to it by the Borrower
pursuant to this Agreement that is identified by such Person
as being "confidential" or "for internal use only" at the
time the same is delivered to the Banks or the Agent,
provided that nothing herein shall limit the disclosure of
any such information (a) after such information shall have

19.10, (b) to the extent required by statute, rule,
regulation or judicial process, (c) to counsel for any of
the Banks or the Agent, (d) to bank examiners or any other

the Agent, or to auditors or accountants, (e) to the Agent
or any Bank, (f) if required pursuant to legal process in
connection with any litigation to which any one or more of
the Banks or the Agent is a party, or in connection with the
enforcement of rights or remedies hereunder or under any
other Loan Document, or (g)  to any assignee or participant

assignee or participant agrees to be bound by the provisions
of Section 19.6.

                 Section 24.  ENTIRE AGREEMENT, ETC.

            The Loan Documents and any other documents executed in
connection herewith or therewith express the entire
understanding of the parties with respect to the
transactions contemplated hereby. Neither this Credit
Agreement nor any term hereof may be changed, waived,
discharged or terminated, except as provided in Section 26.

                      Section 25.  WAIVER OF JURY TRIAL. 

            Each of the Administrative Agent, the Banks and the
Borrower hereby waive its right to a jury trial with respect
to any action or claim arising out of any dispute in
connection with this Credit Agreement, the Notes or any of
the other Loan Documents, any rights or obligations
hereunder or thereunder or the performance of which rights
and obligations.  Except as prohibited by law, all parties
to this Credit Agreement hereby waive any right they may
have to claim or recover in any litigation referred to in
the preceding sentence any special, exemplary, punitive or
consequential damages or any damages other than, or in
addition to, actual damages.  The Borrower (a) certifies
that no representative, agent or attorney of any Bank or the
Administrative Agent has represented, expressly or
otherwise, that such Bank or the Administrative Agent would
not, in the event of litigation, seek to enforce the
foregoing waivers and (b) acknowledges that the
Administrative Agent and the Banks have been induced to
enter into this Agreement, the other Loan Documents to which
it is a party by, among other things, the waivers and
certifications contained herein.

            Section 26.  CONSENTS, AMENDMENTS, WAIVERS, ETC.

            Any consent or approval required or permitted by this
Credit Agreement to be given by the Banks may be given, and
any term of this Credit Agreement, the other Loan Documents
or any other instrument related hereto or mentioned herein
may be amended, and the performance or observance by the
Borrower of any terms of this Credit Agreement, the other
Loan Documents or such other instrument or the continuance
of any Default or Event of Default may be waived (either
generally or in a particular instance and either
retroactively or prospectively) with, but only with, the
written consent of the Borrower and the written consent of
the Majority Banks.  Notwithstanding the foregoing, the rate
of interest on the Notes (other than interest accruing
pursuant to Section 6.10.2 following the effective date of
any waiver by the Majority Banks of the Default or Event of
Default relating thereto) hereunder, and the amount of the
Commitments of the Banks and the amount of commitment fee or
Letter of Credit Fees and the amount and time and any other
term or condition or application of any mandatory prepayment
under Section 4.5, may not be changed without the written
consent of the Borrower and the written consent all of the
Banks; the Revolving Credit Loan Maturity Date and the Term
Loan Maturity Date may not be postponed without the written
consent of all of the Banks; any substantial portion of the
Collateral (as defined in the Pledge Agreement) may not be
released without the written consent of all of the Banks
except (a) to the extent expressly contemplated by the
Supplemental Indenture and the Pledge Agreement and (b) to
the extent the aggregate principal amount of the Collateral
Bonds exceeds one-hundred and ten percent (110%) of the sum
of the aggregate Revolving Credit Commitments and the
outstanding principal amount of the Term Loans; this Section
26 and the definition of Majority Banks may not be amended,
without the written consent of all of the Banks; and the
amount of the Agent's Fee or any Letter of Credit Fees
payable for the Administrative Agent's account and Section
16 may not be amended without the written consent of the
Administrative Agent.  No waiver shall extend to or affect
any obligation not expressly waived or impair any right
consequent thereon.  No course of dealing or delay or
omission on the part of the Administrative Agent or any Bank
in exercising any right shall operate as a waiver thereof or
otherwise be prejudicial thereto.  No notice to or demand
upon the Borrower shall entitle the Borrower to other or
further notice or demand in similar or other circumstances.

                      Section 27.  SEVERABILITY.

            The provisions of this Credit Agreement are severable
and if any one clause or provision hereof shall be held
invalid or unenforceable in whole or in part in any
jurisdiction, then such invalidity or unenforceability shall
affect only such clause or provision, or part thereof, in
such jurisdiction, and shall not in any manner affect such
clause or provision in any other jurisdiction, or any other
clause or provision of this Credit Agreement in any
jurisdiction.

                 Section 28.  TRANSITIONAL ARRANGEMENTS.

            Section 28.1.  Chase Credit Agreement Superseded.  

            This Credit Agreement shall supersede the Chase Credit
Agreement in its entirety, except as provided in this
Section 28.  On the Closing Date, the rights and obligations
of the parties under the Chase Credit Agreement and the
"Revolving Credit Notes" and the "Term Notes" as defined
therein shall be subsumed within and be governed by this
Credit Agreement and the Revolving Credit Notes and Term
Notes, respectively.

            Section 28.2.  Return and Cancellation of
Notes.      

Upon its receipt of the Notes to be delivered hereunder on
the Closing Date, each Bank will promptly return to the
Borrower, marked "Canceled", the "Revolving Credit Notes"
and the "Term Notes" of the Borrower held by such Bank as a
Prior Lender pursuant to, and as defined in, the Chase
Credit Agreement, if any.

            Section 28.3.  Interest and Fees Under Superseded
Agreement.  

            All interest and all commitment, facility and other
fees and expenses owing or accruing under or in respect of
the Chase Credit Agreement shall be calculated as of the
Closing Date in accordance with the Transitional
Arrangements Letter and the Borrower shall be responsible
for such fees, including any breakage fees.

            Section 28.4.  No Claims Under Chase Credit
Agreement.       

Each Bank wishes (and the Borrower agrees) to eliminate any
possibility that any past conditions, acts, omissions,
events, circumstances or matters would impair or otherwise
adversely affect such Bank's rights, interests, contracts,
collateral security or remedies.  Therefore, the Borrower
unconditionally releases, waives and forever discharges (i)
any and all liabilities, obligations, duties, promises or
indebtedness of any kind of such Bank or Prior Lender to the
Borrower regarding the execution, delivery or performance of
the Chase Credit Agreement or any of the other Loan
Documents (as defined in the Chase Credit Agreement), except
the obligations to be performed by such Bank for the
Borrower as expressly stated in this Credit Agreement and
the other Loan Documents (as defined in this Credit
Agreement), and (ii) all claims, offsets, causes of action,
suits or defenses of any kind whatsoever (if any), whether
known or unknown, which the Borrower might otherwise have
against such Bank or Prior Lender or any of their directors,
offices, employees or agents, in either case (i) or (ii), on
account of any condition, act, omission, event, contract,
liability, obligation, indebtedness, claim cause of action,
defense, circumstance or matter of any kind whatsoever which
existed, arose or occurred at any time prior to the date
hereof regarding the execution, delivery or performance of
the Chase Credit Agreement or any of the Loan Documents (as
defined in the Chase Credit Agreement).

            Section 28.5.   Interbank Settlements.  

            On the Closing Date, each of the Banks shall pay to
each of the Prior Lenders such amounts as may be necessary
so as to result in the outstanding amount of Loans made by
each Bank being equal to such Bank's Commitment Percentage
and/or Term Loan Percentage of the aggregate amount of Loans
outstanding as of the Closing Date.  The Borrower and the
Banks hereby agree that all amounts paid to any Bank or
Prior Lender by any other Bank in connection with interbank
settlements with respect to Loans outstanding immediately
prior to the date hereof shall be deemed to constitute Loans
under the Credit Agreement.

            Section 28.6.   Intercreditor Agreement with Bangor
Energy Banks.  The Banks hereby agree to, ratify and confirm the Bangor
Energy Intercreditor Agreement on the terms set forth
therein, and further confirm that any matters concerning
such agreement or the intercreditor arrangements set forth
therein shall be governed by the provisions of the Bangor
Energy Intercreditor Agreement.
