   24

         (a) The  Borrower  agrees to  protect,  defend  and hold  harmless  the
Trustee and the Issuer and their respective directors, agents, officers, members
and employees (each an "Indemnified  Party") from and against any claim, demand,
suit,  action,  liability,  loss,  damage,  fine,  penalty or expense (including
out-of-pocket  and  incidental  expenses  and  legal  fees) or other  proceeding
whatsoever by any Person, including any violation or breach of any Environmental
Law by the Borrower,  or any Environmental  Claim arising out of the management,
use, control,  ownership or operation of the Facility  (collectively,  "Losses")
imposed on, incurred by or asserted against the Borrower, arising or purportedly
arising from or in connection with the Financing Documents,  the Indenture,  the
Bonds, or the  transactions  contemplated by or actions taken under any thereof,
or,  with  respect to the  Trustee,  for  following  any  instructions  or other
directions upon which the Trustee is authorized to rely pursuant to the terms of
the Indenture,  the Bonds or the financing Documents,  except for any bad faith,
willful misconduct,  material  misrepresentation or gross negligence on the part
of the Indemnified  Party. The Borrower agrees to indemnify and hold the Trustee
and  its  directors,   officers,   agents  and  employees   (collectively,   the
"Indemnitees")  harmless  from  and  against  any and all  claims,  liabilities,
losses,  damages, fines,  penalties,  and expenses,  including out-of-pocket and
incidental  expenses and legal fees  ("Losses") that may be imposed on, incurred
by, or  asserted  against,  the  Indemnitees  or any of them for  following  any
instructions  or other  directions  upon which the Trustee is authorized to rely
pursuant to the terms of the Indenture, the Bonds or the Financing Documents.

         (b) The Borrower releases each Indemnified Party from, agrees that each
Indemnified  Party shall not be liable for, and agrees to hold each  Indemnified
Party harmless against any damages or reasonable expenses, including (subject to
subparagraph  (d) of this  Section)  reasonable  charges  of  counsel,  incurred
because of any  investigation,  review or lawsuit  commenced by any Person other
than the Borrower with respect to the Financing  Documents,  the Indenture,  the
Bonds or the Facility,  except for any bad faith,  willful misconduct,  material
misrepresentation or gross negligence on the part of the Indemnified Party.

         (c) All covenants,  stipulations,  promises, agreements and obligations
of  the  Issuer   contained   herein  shall  be  deemed  to  be  the  covenants,
stipulations,  promises, agreements and obligations of the Issuer and not of any
member, officer or employee of the Issuer in his or her individual capacity, and
no  recourse  shall be had for the  payment  of the Loan or the Bonds or for any
claim based thereon or hereunder against any member,  officer or employee of the
Issuer or the Trustee or any natural person executing the Bonds.

         (d) In case any  action  shall be  brought  against  one or more of the
Indemnified  Parties  based  upon  any of the  above  and in  respect  of  which
indemnity  may be sought  against the  Borrower,  such  Indemnified  Party shall
notify the Borrower in writing,  enclosing a copy of all papers served,  but the
omission so to notify the  Borrower  of any such action  shall not relieve it of
any liability which it may have to any  Indemnified  Party other than under this
Section 5.5. In case


                                       20
   25

any such  action  shall be brought  against any  Indemnified  Party and it shall
notify the Borrower of the commencement  thereof, the Borrower shall be entitled
to  participate  in and, to the extent that it shall wish, to assume the defense
thereof with counsel  reasonably  satisfactory to such  Indemnified  Party,  and
after  notice from the  Borrower  to such  Indemnified  Party of the  Borrower's
election so to assume the defense  thereof the  Borrower  shall not be liable to
such  Indemnified  Party for any legal or other expenses,  other than reasonable
costs of  investigation,  subsequently  incurred  by such  Indemnified  Party in
connection with the defense thereof.  The Indemnified Party shall have the right
to employ its own counsel in any such action,  but the fees and expenses of such
counsel  shall  be at the  expense  of such  Indemnified  Party  unless  (i) the
employment  of  counsel by such  Indemnified  Party has been  authorized  by the
Borrower,  (ii) the Indemnified Party shall have reasonably concluded that there
is a conflict of interest between the Borrower and the Indemnified  Party in the
defense of such action (in which case the  Borrower  shall not have the right to
direct the defense of such action on behalf of the Indemnified  Party), or (iii)
the Borrower shall not in fact have employed counsel reasonably  satisfactory to
the Indemnified Party to assume the defense of such action.

         (e) In the event the  Borrower  fails to pay any amount or perform  any
act under the Financing Documents, the Trustee or the Issuer may, but shall have
no  obligation  to,  pay the  amount  or  perform  the act,  in which  event the
reasonable  costs,  disbursements,  expenses  and  charges of  counsel  thereof,
together with interest  thereon from the date the expense is paid or incurred at
the  highest  prime  rate  from  time to time as  published  in The Wall  Street
Journal,  plus two per centum (2%), shall be an additional  obligation hereunder
payable on demand.

         (f) The  obligations  of the Borrower  under this section shall survive
the  termination of this  Agreement.  This section is not for the benefit of any
person not an Indemnified  Party,  and no waiver of the Maine Tort Claims Act or
other applicable law is intended.

has expired for the  restoration  thereof,  and the Capital Reserve Fund has not
been fully restored pursuant to Section 5.09 of the Indenture, without the prior
written consent of the Issuer, the Borrower may not assign its rights, interests
or obligations hereunder or under the Loan Note or sell the whole or any part of
the  Facility or lease the whole or any part of the Facility  necessary  for the
operation of the Facility at its designed capacity.

         (b) Without the prior written  consent of the Issuer,  the Borrower may
not assign or transfer this Agreement or any of its right,  title or interest in
any of the Facility Agreements or any Financing Agreements.

is prohibited,  limited, or regulated by any federal,  state, county,  regional,
local, or other  governmental  authority or which,  if not so regulated,  to the
knowledge of the Borrower  poses a substantial  hazard to health and safety (all
of which are referred to collectively herein as "Hazardous Substances"), and (2)
the  Borrower  is  not  the  subject  of any  existing,  pending  or  threatened
investigation or inquiry by, or of any remedial order or obligation issued by or
at the behest of, any  governmental  authority under any law, rule or regulation
pertaining to health or the  environment  except as described in the engineering
report  required by paragraph 13 of the Loan  Commitment  from the Issuer to the
Borrower with respect to the Loan.

         (b) The Borrower will comply with all applicable Environmental Laws.

         (c) Promptly upon becoming aware of any Environmental  Claim pending or
threatened against the Borrower, or any past or present acts, omissions,  events
or circumstances that could form the basis of such Environmental Claim, which if
adversely  resolved,  individually  or in the  aggregate,  could have a Material
Adverse  Effect,  the Borrower shall give the Trustee notice  thereof,  together
with a written statement of an Authorized Representative of the Borrower setting
forth the details  thereof and any action with respect thereto taken or proposed
to be taken by the Borrower.

         Section VI.10 Default and Litigation  Notification.  The Borrower shall
deliver to the Issuer and the Trustee,  within one hundred five (105) days after
the close of each fiscal year of Borrower, a certificate signed by an Authorized
Representative  to the  effect  that  the  Borrower  is in  compliance  with the
provisions  of  the  Financing   Documents  or  specifying  the  nature  of  the
noncompliance and the steps the Borrower is taking to correct any noncompliance.
Upon  becoming  aware of any condition or event which  constitutes,  or with the
giving of notice or the  passage of time would  constitute,  an Event of Default
under this Agreement, or an Event of Default (as defined in the Indenture) under
the Indenture, the Borrower promptly shall deliver to the Issuer and the Trustee
a notice  stating the existence and nature thereof and specifying the corrective
steps the Borrower is taking with respect  thereto.  The Borrower shall promptly
notify  the  Issuer  and  Trustee  of  the   commencement   of  any  litigation,
administrative,  enforcement or other proceeding by or against it, or the threat
thereof, in which an unfavorable  outcome could materially  adversely affect the
operation of the Borrower's business or compliance with the Financing Documents.

         Section  VI.11  Insurance.  The  Borrower  shall  maintain an insurance
policy  against  liability   appropriate  for  Borrower's   business  (including

and self insurance provisions selected by the Borrower.

         Section VI.12 Additional covenants and Agreements.  The Borrower hereby
agrees to those  Additional  Covenants  and other matters set forth in Exhibit A
hereto.

         Section VI.13 No Liability of the Issuer.  Any obligation of the Issuer

Financing Documents, is not a general obligation of the Issuer or payable in any
manner from  revenues  raised by taxation or from the general funds and accounts
of the  Authority,  but shall be payable  solely out of  Revenues  and the other
moneys pledged under the Indenture.  In making the agreements,  provisions,  and
covenants  set forth in the  Indenture  and this  Agreement,  the Issuer has not
obligated itself except with respect to the Electric Rate Stabilization  Project
or the Facility and the application of the Revenues and the other moneys pledged
under the Indenture.  All covenants,  stipulations,  promises,  agreements,  and
obligations  of the Issuer  contained  herein  shall be deemed to be  covenants,

on the Bonds, for the performance of any obligation hereunder,  or for any claim
based thereon or hereunder against any such member,  officer,  agent or employee
or against any natural  person  executing  the Bonds.  No such member,  officer,
agent,  employee, or natural person is or shall become personally liable for any
such payment, performance, or other claim, and in no event shall any monetary or

other claim.

expectation  of the Borrower set forth in the Tax  Regulatory  Agreement  are by
this reference incorporated in this Agreement as though fully set forth herein.

         (b) If there shall occur a Determination of Taxability,  and the Issuer
exercises its option to require the redemption in whole of the Bonds, the Issuer
shall  provide to the Borrower  written  notice of its exercise of the option to
redeem the Bonds,  which notice shall  specify a Redemption  Date not later than
ninety (90) days from the date of such notice,  and the  Borrower  shall pay not
later than  thirty  (30) days  prior to the  Redemption  Date to the  Trustee an
amount  sufficient,  together  with all other  amounts  held by the  Trustee and
available  under  the  Indenture  for such  purpose,  to redeem  all Bonds  then
Outstanding, in accordance with Section 2.04(e) of the Indenture.

         (c) The obligation of the Borrower to make the payments provided for in
this Section shall be absolute and unconditional,  and the failure of the Issuer
or the Trustee to execute or deliver or cause to be delivered  any  documents or
to take any action  required under this Agreement or otherwise shall not relieve
the Borrower of its obligations  under this Section.  Notwithstanding  any other
provision of this Agreement or the Indenture,  the Borrower's  obligations under
this Section shall survive the termination of this Agreement and the Indenture.

         (d)  Notwithstanding  the  provisions of paragraph (b) above if, in the
opinion of Bond Counsel (as defined in the  Indenture),  redemption of less than
all of the  Bonds  will  preserve  the  tax-exempt  status  of  interest  on the
remaining Bonds, then only such amount need be redeemed, the particular Bonds to
be redeemed to be selected by lot by the Trustee or otherwise as required by the
Indenture or as specified in such final Determination of Taxability or opinion.

         Section VI.15  Maintenance of Facility  Agreements.  The Borrower shall
maintain such Facility  Agreements  in effect as shall be  sufficient,  together
with other  Revenues,  to permit (i) the operation of the Facility to be carried
out as  contemplated  hereby and by the  Indenture  and (ii) the  payment of the
amounts  required to be paid by the  Borrower  hereunder  and under the Facility
Agreements, the Financing Documents and the Indenture.

                  performed  (other  than as  referred  to in Section  7.1(a)(i)
                  hereof) for a period of thirty (30) days after written notice,
                  specifying such failure,  requesting that it be remedied,  and
                  stating that it is a notice of default,  has been given to the
                  Borrower  by the  Trustee  (except  in the case of  Unassigned
                  Issuer's Rights) or by the Issuer,  unless the Trustee (except

                  waiver of any covenant,  condition or agreement in or referred
                  to  in  this  Agreement  constituting  a  part  of  Unassigned
                  Issuer's Rights);  provided,  however, if said failure be such
                  that it cannot be corrected within the applicable  period,  it
                  shall not constitute an Event of Default if corrective  action
                  is instituted by the Borrower within the applicable period and
                  diligently  pursued until the failure is corrected,  but only,
                  with  respect to  covenants,  conditions  and  agreements  not
                  included in  Unassigned  Issuer's  Rights,  if such failure is
                  corrected  within ninety (90) days after the written notice of
                  default  related  thereto  unless the  Trustee  shall agree in
                  writing to an extension of such time prior to its  expiration;

                  insolvent  or  bankrupt,  petitions or applies to any tribunal

                  Borrower   indicates   its   consent  to,   approval   of,  or
                  acquiescence  in any such proceeding or the appointment of any
                  such   receiver  of  or  trustee  for  the   Borrower  or  any
                  substantial part of its property;  or the Borrower suffers any
                  such  receivership or trusteeship to continue  undischarged or
                  unstayed for a period of sixty (60) days; and/or

                  (iv) there shall occur an "Event of Default" specified in
                  Section 7.01(a) or (b) of the Indenture; and/or

                  (v) any  representation  or warranty  made by the  Borrower in
                  this  Agreement,  or any material  representation  or warranty
                  made  by the  Borrower  in any  instrument,  other  agreement,
                  statement  or  certificate  furnished  by or on  behalf of the
                  Borrower to the Issuer or the Trustee in connection  with this
                  Agreement  or the  purchase  of the Bonds  including,  without
                  limitation, the Tax Regulatory Agreement, proves untrue in any
                  material  respect  as of the date of the  issuance  or  making
                  thereof; provided, however, if any of the facts upon which the
                  representations  and  warranties of the Borrower are based are
                  capable  of   correction  or  cure  to  conform  to  any  such
                  representation or warranty, there shall be no Event of Default
                  until  passage of a period of thirty  (30) days after  written
                  notice, specifying such failure and requesting


                                       25
   30

                  that it be  remedied,  given to the Borrower by the Trustee or
                  the  Holders  of   twenty-five   percent  (25%)  in  aggregate
                  principal amount of the Bonds then Outstanding; and/or

                  (vi) the  Borrower  has failed to provide  funds in the amount
                  and by the time  specified by the Issuer in a notice  electing
                  to  exercise  the option to redeem the Bonds  provided  by the
                  Issuer to the Borrower pursuant to Section 6.14(b) hereof.

         The declaration of an Event of Default under clause (iii) of subsection
(a) above,  and the  exercise of remedies  upon any such  declaration,  shall be
subject to any  applicable  limitations  of federal  bankruptcy law affecting or
precluding  that  declaration or exercise  during the pendency of or immediately
following any bankruptcy, liquidation or reorganization proceedings.

         (b) Paragraph  (ii) of the foregoing  Section  7.1(a) is subject to the
following  limitations:  if by reason of force majeure the Borrower is unable in
whole or in part to carry out the agreements on its part herein contained, other
than the obligations on the part of the Borrower  contained in Sections 4.2, 4.3
and 6.7  hereof,  the  Borrower  shall  not be  deemed  in  default  during  the
continuance  of such  inability.  The term "force  majeure" as used herein shall
mean, without  limitation,  the following:  Acts of God; strikes,  lockouts,  or
other  industrial  disturbances;  acts of public enemies;  orders of any kind of
governmental  authority or any of their departments,  agencies or officials,  or
any civil or military authority;  insurrections; riots; landslides; earthquakes;
fires; storms; droughts; floods; explosions;  breakage;  malfunction or accident
to facilities,  machinery,  transmission pipes, or canals; or any other cause or
event not reasonably  within the control of the Borrower.  The Borrower  agrees,
however,  to remedy with all reasonable  dispatch the cause or causes preventing
the Borrower from carrying out this  Agreement to the extent that such remedy is
reasonably  within the ability of the Borrower;  provided that the settlement of
strikes,  lockouts,  and other  industrial  disturbances  shall be left entirely
within the discretion of the Borrower, and the Borrower shall not be required to
make  settlement  of strikes,  lockouts  and other  industrial  disturbances  by
acceding to the demands of the opposing party or parties.

         Section VII.2  Remedies on Default.

         (a)  Whenever  any Event of Default  referred  to in Section 7.1 hereof
shall have  happened and be  continuing,  the Issuer or the Trustee may take any
one or more of the following  remedial steps (except that the Trustee shall have
no right to enforce Unassigned Issuer's Rights):

                  (i) The Issuer or the Trustee  may declare an amount  equal to
                  the  unpaid  principal  amount  of the Loan  and the  interest
                  accrued  thereon  to  the  date  of  such  declaration  to  be
                  immediately due and payable, whereupon the same shall become


                                       26
   31

                  immediately due and payable, and which amount the Borrower
                  hereby agrees to pay or cause to be paid; and/or

                  (ii) The Issuer or the Trustee may take whatever action at law
                  or in equity may appear  necessary or desirable to collect the
                  payments and other  amounts then due and  thereafter to become
                  due  or  to  enforce   performance   and   observance  of  any
                  obligation,  agreement, or covenant of the Borrower under this
                  Agreement or the Facility Agreements.

Notwithstanding the foregoing, if any such Event of Default relates solely to an
Event of Default  caused by a default under  Section 6.14 hereof,  the Issuer or
the Trustee may take only the remedial  steps set forth in clause (ii) above and
not those in clause (i) above.

         (b) Any amounts  collected  pursuant to action taken under this Section
shall  be paid  into the Debt  Service  Fund or the  Capital  Reserve  Fund,  as
required by the Indenture,  and applied in accordance with the provisions of the
Indenture  or, if all of the Bonds and other  amounts  due  hereunder  have been
fully paid (or  provision for payment  thereof has been made in accordance  with
the provisions of the Indenture),  to the Borrower (except, to the extent of any
payments  by the State into the  Capital  Reserve  Fund  pursuant to the Act and
Section 5.09 of the Indenture not otherwise reimbursed, to the Issuer).

         (c)  Except to the  extent  of any such  collection,  no  action  taken
pursuant to this Section shall relieve the Borrower from such of the  Borrower's
obligations pursuant to Sections 4.2, 4.3 and 6.7 hereof which shall survive any
such action, and the Issuer or the Trustee may take whatever action at law or in
equity as may appear necessary and desirable to collect all amounts then due and
thereafter to become due and/or to enforce the performance and observance of any
obligation,  agreement  or covenant of the Borrower  hereunder  (except that the
Trustee shall have no right to enforce Unassigned Issuer's Rights).

         Section VII.3 No Remedy Exclusive; Trustee and Noteholders Deemed Third
Party  Beneficiaries.  No remedy herein conferred upon or reserved to the Issuer
is intended to be exclusive of any other available remedy or remedies,  but each
and every such  remedy  shall be  cumulative  and shall be in  addition to every
other remedy given under this  Agreement or now or hereafter  existing at law or
in equity or by statute.  No delay or  omission  to exercise  any right or power
accruing  upon any  default  shall  impair  any such  right or power or shall be
construed to be a waiver thereof,  but any such right and power may be exercised
from  time to time and as often as may be  expedient.  In order to  entitle  the
Issuer or the Trustee to exercise any remedy reserved to it in this Article,  it
shall not be  necessary  to give any  notice,  other than such  notice as may be
herein expressly required.  Subject to any applicable restriction on enforcement
contained  in the  Indenture,  such rights and  remedies as are given the Issuer
hereunder shall also extend to the Trustee, and the


                                       27
   32

Trustee and the  Bondholders  shall be deemed third party  beneficiaries  of all
covenants and agreements  herein  contained,  whether described as rights of the
Trustee  or  Holders  or as  rights  of the  Issuer,  except  in the case of the
Bondholders  as to the rights of the Trustee for its own account,  and except in
each and every such case Unassigned Issuer's Rights.

         Section VII.4 No Additional  Waiver Implied By One Waiver. In the event
any agreement contained in this Agreement should be breached by either party and
thereafter  waived by the  other  party or the  Trustee,  such  waiver  shall be
limited to the particular  breach so waived and shall not be deemed to waive any
other breach hereunder.

                                    EXHIBIT A

                        ADDITIONAL COVENANTS OF BORROWER

1.    The existing general partners of the Borrower may not sell, assign,
      transfer or otherwise encumber their general partnership interest in the
      Borrower without the prior written consent of the Authority, which consent
      shall not be unreasonably withheld or delayed; provided, however, that no
      consent of the Authority shall be required with respect to (a) a transfer
      from one general partner to its affiliate, or to another general partner
      or its affiliate, or to an entity controlled by any or all of such general
      partners and affiliates, or (b) a transfer to the MRC or the
      municipalities for which the MRC acts as agent, in accordance with the
      Waste Disposal Agreements, or (c) the grant of a security interest in or
      lien on the partnership interests in the Borrower by the holder of such
      partnership interest to secure loan facilities extended to it or an
      affiliate.

2.    The Borrower shall promptly notify the Authority of the occurrence of any
      litigation (including litigation concerning affiliates or subsidiaries)
      which may materially impact the Borrower. "Material" includes, but is not
      limited to, any claim or action with a demand of $1,000,000 or greater.
      Such notice shall be in writing and shall describe the matter and the
      steps taken and then expected to be taken by the Borrower (or its
      affiliates or subsidiaries) affected with respect thereto. A prompt copy
      of any filing with the Securities and Exchange Commission shall constitute
      adequate notification for purposes of this paragraph.

3.    The Borrower shall furnish the Issuer with copies of its annual budget for
      operations and maintenance (the "Operating Budget") for each Fiscal Year,
      as adopted, by November 15 of each year, and shall furnish the Issuer with
      copies of any amendment thereto promptly after the adoption thereof. In
      the event the Borrower requests any requisition from the Operating Account
      under the Indenture which will make the aggregate amount requested in any
      Fiscal Year in excess of 110% of the amount of the originally adopted
      Operating Budget, the Issuer may, at the expense of the Borrower, retain
      the services of a consultant to provide a report on the Borrower and its
      operations, management and such other matters as the Chief Executive
      Officer of the Issuer deems pertinent.

4.    The Borrower shall provide the Issuer with quarterly  unaudited  financial
      statements,  without  footnotes or year end  adjustments  but otherwise in
      accordance  with  generally   accepted   accounting   principles,   within
      forty-five days after the end of each quarter.

5.    The Borrower  shall  provide the Issuer with a copy of its annual  audited
      financial statements within 105 days after the close of its Fiscal Year.

6.    The Borrower shall observe and comply in all material respects with all
      applicable laws, regulations, ordinances, rules, and orders (including
      without limitation those relating to


                                       A-1
   39

      zoning, land use, environmental protection, air, water and land pollution,
      wetlands, health, equal opportunity,  minimum wages, worker's compensation
      and  employment  practices)  of any  federal,  state,  municipal  or other
      governmental  authority except during any period during which the Borrower
      at its  expense  and in its name  shall be in good  faith  contesting  its
      obligations to comply therewith.

7.    The  Borrower  shall  not  create,  incur,  assume  or permit to exist any
      mortgage,  lien,  charge,  security  interest or other  encumbrance on any
      property  or asset of the  Borrower,  except  Permitted  Encumbrances  (as
      defined in the Mortgage).

8.    The Borrower shall apply the Loan proceeds only as described in Section
      3.2 of this Agreement.

9.    The Borrower  shall  promptly  notify the Issuer of any  material  adverse
      change in the Borrower's business operations or financial condition.

10.   The Borrower  shall pay all costs and  expenses  incurred by the Issuer in
      connection  with the  issuance of the Bonds and  servicing of the Loan and
      the  Bonds,  to the extent  not paid from  other  sources.  Such costs and
      expenses  shall  include but shall not be limited to costs and expenses of
      employees of the Issuer including in-house counsel in processing servicing
      requests during the term of the Loan.

11.   The Borrower shall not incur additional Indebtedness in excess of
      $15,000,000 unless (a) such Indebtedness is refunding Indebtedness which
      does not increase the Borrower's aggregate level of Indebtedness, or (b)
      the issuance of such Indebtedness does not reduce the Debt Service
      Coverage (as defined below) below the lesser of (i) the Debt Service
      Coverage prior to the issuance of new debt or (ii) 1.3x, or (c) such
      additional Indebtedness is required by a change in law occurring after the
      Loan closing or is required to comply with an order or decision of any
      governmental agency or authority with authority to issue or make and
      enforce the same, or (d) the Chief Executive Officer of the Issuer
      consents in writing thereto.

      For the purpose of this covenant,  Debt Service  Coverage means:  earnings
      before  income taxes + interest for the previous 12 months +  depreciation
      for the previous 12 months + amortization for the previous 12 months (less
      or plus  extraordinary1  income or losses)  divided by:  interest  for the
      previous 12 months + principal  payments  for the previous 12 months + the
      projected 12 months of principal and interest for all Indebtedness.

12.   The  Borrower  shall  immediately  assign to the Trustee all  payments and
      revenues the Borrower is entitled to receive  under any  agreement for the
      sale of power,  energy,  steam,  waste  disposal  services or other output
      capacity  for  services  of the  Facility  or the  receipt of waste by the
      Facility.

                                 PROMISSORY NOTE

No. 1                                                               $44,995,000

         Penobscot  Energy  Recovery  Company,  Limited  Partnership,  a limited
partnership  duly  organized  and existing  under the laws of the State of Maine
(the  "Borrower"),  for value received,  promises to pay to the order of Finance
Authority of Maine (the "Authority") the principal sum of $44,995,000 and to pay
(i) interest on the unpaid principal  balance thereof from the date hereof until
fully and  finally  paid at the  interest  rates  borne by the Bonds (as defined
below) from time to time and as further  described in the  Agreement (as defined
below), and (ii) those additional  payments referred to in Section 4.3(b) of the
Agreement.

         This  promissory  note has been  executed and delivered by the Borrower
pursuant to a certain  Loan  Agreement  (the  "Agreement"),  dated as of June 1,
1998, between the Authority and the Borrower.  Terms used but not defined herein
shall have the meanings ascribed to such terms in the Agreement.

         This  promissory  note is  issued to  evidence  the  obligation  of the
Borrower  under the Agreement to repay the Loan made by the  Authority  from the
proceeds of the sale of its Electric Rate Stabilization Revenue Refunding Bonds,
Series 1998A  (Penobscot  Energy  Recovery  Company,  LP) and its Electric  Rate
Stabilization  Revenue Refunding Bonds,  Series 1998B (Penobscot Energy Recovery
Company,  LP) (together,  the "Bonds"),  together with interest  thereon and all
other amounts, fees, penalties,  adjustments,  expenses,  counsel fees and other
payments of any kind  required to be paid by the Borrower  under the  Agreement.
The Agreement  further  provides for the payment of interest on this  promissory
note at other rates in certain circumstances.

         The Financing  Documents (as defined in the  Indenture),  including the
Agreement and this  promissory  note,  have been assigned to The Chase Manhattan
Bank (the  "Trustee")  acting  pursuant to a Trust Indenture dated as of June 1,
1998 (the  "Indenture")  between  the  Authority  and the  Trustee,  except with
respect to the  Unassigned  Issuer's  Rights,  which are not so  assigned.  Such
assignment is made as security for the payment of the Bonds.

         As provided in the  Agreement  and subject to the  provisions  thereof,
payments  hereon are to be made at the  principal  office of the Trustee,  or at
such other place in the United  States as the Trustee may direct in writing,  by
wire  transfer,  in the amounts and at the times  required by the Indenture with
respect to the Bonds.  Loan payments hereon shall be paid, or caused to be paid,
by the Borrower in an amount  which,  when added to the other  moneys  available
therefor in the Debt Service  Fund,  will be  sufficient to pay the principal of
and  interest on the Bonds due and  payable on each  Interest  Payment  Date and
Principal Payment Date, whether at maturity or upon


                                       1
   42

declaration accelerating the maturity, upon mandatory sinking fund redemption in
accordance with the Indenture, or otherwise.

         With respect to payments  due  hereunder,  time is of the essence.  All
payments must be in immediately available funds as and when due.

         The Borrower shall make payments on this  promissory  note on the dates
and in the amounts  specified  herein and in the Agreement and in addition shall
make such other payments as are required to be made by the Borrower  pursuant to
the Agreement and the Indenture.  This  promissory note is subject to prepayment
to the extent the Loan is prepaid pursuant to the Agreement.

         In the event the Borrower  shall fail to make, or cause to be made, any
of the  payments  required  hereby  or by the  Agreement,  the  unpaid  item  or
installment  shall  continue as an obligation of the Borrower  until such amount
shall have been fully paid, and the Borrower agrees to pay, or cause to be paid,
the same  with  interest  thereon  from the date of  failure  or, in the case of
payments required by Sections  4.3(a)(ii),  (iii) and (v) of the Agreement,  the
date 30 days after the date on which the  Borrower is notified  thereof,  at the
interest  rate borne by the Bonds until fully paid,  except as otherwise  may be
provided by Article XIII of the Indenture.(1)

         All payments  hereunder  shall be payable in lawful money of the United
States of America and shall be made to the Authority,  the Trustee,  or the Note
Insurer,  as provided in the Agreement.  Loan payments shall be deposited in the
Revenue  Fund  created by the  Indenture.  Except as  otherwise  provided in the
Indenture,  such Loan payments shall be used by the Trustee to pay the principal
of and interest on the Bonds when due.

         The obligation of the Borrower to make the payments required  hereunder
and to perform and observe the other  agreements  on its part  contained  herein
shall be absolute and  unconditional,  irrespective of any defense or any rights
of set-off,  recoupment or counterclaim  which the Borrower may have against the
Authority  or the  Trustee.  The  Borrower  shall  pay,  or  cause  to be  paid,
absolutely net all payments required hereunder and under the Agreement,  free of
any deductions and without postponement, abatement or diminution, but subject to
applicable  provisions of the Indenture.  Except to the extent  provided in this
paragraph,  nothing contained in this paragraph shall be construed to prevent or
restrict  the  Borrower  from  asserting  any  rights  it may have  against  the
Authority,  the Trustee or any other Person under the Financing Documents or the
Indenture or under any provisions of law.

         Whenever an Event of Default under Section 7.01(a),  (d), (e) or (f) of
the Indenture shall have occurred and, as a result thereof, the principal of the
Bonds then outstanding,  and interest accrued thereon,  shall have been declared
to be immediately due and payable pursuant to Section 7.03 of the Indenture, the
unpaid principal amount of and accrued interest on this promissory note

shall also be due and payable on the date on which the principal of and interest
on the Bonds  shall  have  been  declared  due and  payable;  provided  that the
annulment of a declaration of acceleration  with respect to the Bonds shall also
constitute an annulment of any  corresponding  declaration  with respect to this
promissory note.

         The Borrower further waives diligence, demand, presentment for payment,
notice of nonpayment,  protest and notice of protest, and notice of any renewals
or extension of this promissory  note. Any delay on the part of the Authority or
the Trustee in exercising any right  hereunder  shall not operate as a waiver of
any such right,  and any waiver  granted with  respect to one default  shall not
operate as a waiver in the event of any subsequent default.

         Notwithstanding  any other  provisions of this promissory  note,  there
shall be no recourse against any general or limited partner of the Borrower,  or
any of their respective affiliates, stockholders, partners, officers, directors,
employees or agents,  for any  liability to the Authority or the holders of this
promissory  note or the  obligations  arising in  connection  with any breach or
default  under this  promissory  note  except to the extent the same is enforced
against and limited to the Borrower or the  Collateral,  and the Authority shall
look  solely  to the  Borrower  and  the  Collateral  in  enforcing  rights  and
obligations  under  and in  connection  with this  promissory  note and the Loan
Agreement,  the Mortgage,  the Indenture,  or any other Borrower  Documents,  or
pledge  of the  Collateral.  The  limitations  on  recourse  set  forth  in this
paragraph  shall survive the  termination of this  promissory  note and the full
payment and performance of the  obligations of the Borrower  hereunder and under
the  Loan  Agreement,  the  Indenture,  the  Mortgage  and  the  other  Borrower
Documents.
