   material respects as of the date hereof and as of the Closing Date.
   
          3.2  PERFORMANCE.  Buyer shall have performed and complied in all
   material respects with all agreements, obligations and conditions required by
   this Agreement to be performed or complied with by it including, without
   limitation, payment of the Purchase Price and the payments set forth in
   Section 1.4(a) above and shall have delivered all items required to be
   delivered pursuant to Section 1.5 by it on or prior to the Closing Date.
   
          3.3  TERMINATION AND RELEASE.  (a)  Seller shall have received a
   release and discharge executed by the Agent and (if necessary) the Banks,
   reasonably satisfactory in form and substance to Seller, whereby Seller is
   released from and discharged of its obligations under the Loan Agreement, the
   Security Documents and the Notes (each as defined in the Loan Agreement), and
   such release and discharge shall provide that the Agent and the Banks shall
   have released to Seller and otherwise discharged all mortgages, liens,
   security interests and encumbrances on any property of the Seller whatsoever
   (including without limitation, permits, goods, equipment, intangibles and
   deposit accounts) entered into or obtained by the Agent and the Banks in
   connection with Seller's obligations under the Loan Agreement, the Security
   Documents and the Notes.
   
          (b)  On the Closing Date, Seller shall have received satisfactory
   assurances of payment in cash in immediately available funds on the Escrow
   Release Date of an amount equal to the balance to be on deposit on the Escrow
   Release Date, and all accrued interest thereon, in accounts held as cash
   collateral and/or reserve accounts in connection with the Loan Agreement
   and/or the Security Documents. 
   
          3.4  TRANSMISSION AGREEMENT.  Seller and Buyer shall have entered
   into an agreement on terms and conditions reasonably satisfactory to Seller
   for the transmission of power generated at the Facility from the Facility to
   points at which Buyer's transmission system interconnects with the
   transmission system of other electric utilities for the purpose of enabling
   Seller (or any successor owner or user of the Facility) to compete for the
   sale of capacity and energy to other utilities in the bulk power supply
   market, or (except to the extent such restriction is prohibited by law) to
   entities that are not retail customers of Buyer.  Such agreement shall
   provide for such transmission services at non-discriminatory rates
   customarily available among electric utilities.  To the extent that the
   approval of the Federal Energy Regulatory Commission or other governmental
   agency is required as a condition to the effectiveness of such agreement, at
   Seller's request and upon payment by Seller to Buyer of any required filing
   fee, Buyer will use its best efforts to obtain the requisite approval; such
   approval, however, is not a condition to Seller's obligations to consummate
   the Closing on the Closing Date.
   
          3.5  SPECIAL FACILITIES.  Seller and Buyer shall have entered into
   an agreement, on terms and conditions reasonably satisfactory to Seller and
   no less favorable to Seller than under the Agreement for Installation of
   Special Facilities for Parallel Operation Between Bangor Hydro-Electric
   Company and Babcock-Ultrapower Jonesboro (the "Special Facilities Agreement")
   in effect as of the date of this Agreement, providing for the continued use
   of the Special Facilities (as defined in the Special Facilities Agreement) by
   Seller (or any successor owner or user of the Facility).  To the extent that
   the approval of the MPUC or other governmental agency is required as a
   condition to the effectiveness of such agreement, at Seller's request, Buyer
   will use its best efforts to obtain the requisite approval; such approval,
   however is not a condition to Seller's obligation to consummate the Closing
   on the Closing Date.  In the absence of such approved agreement, Buyer will
   make the Special Facilities available to Seller (and any such successor)
   pursuant to the applicable industrial tariff in effect from time to time.
   
          3.6  DISPATCH SERVICES AGREEMENT.  Seller and Buyer shall have
   entered into an agreement, on terms and conditions reasonably satisfactory to
   Seller, requiring Buyer to provide dispatch services to Seller (or any
   successor owner or user of the Facility) to allow Seller or such successor to
   sell energy and capacity into northeastern power markets.  To the extent that
   the approval of the Federal Energy Regulatory Commission or other
   governmental agency is required as a condition to the effectiveness of such
   agreement, at Seller's request and upon payment by Seller to Buyer of any
   required filing fee, Buyer will use its best efforts to obtain the requisite
   approval; such approval, however, is not a condition to Seller's obligation
   to consummate the Closing on the Closing Date.
   
          3.7  STATION SERVICE RATE AGREEMENT.  Seller and Buyer shall have
   entered into an agreement, on terms and conditions and at a rate reasonably
   satisfactory to Seller, providing for the supply of electric power by Buyer
   to the Facility (notwithstanding any subsequent change in ownership of the
   Facility).  To the extent that the approval of the MPUC or other governmental
   agency is required as a condition to the effectiveness of such agreement, at
   Seller's request, Buyer will use its best efforts to obtain the requisite
   approval;  such approval, however, is not a condition to Seller's obligation
   to consummate the Closing on the Closing Date.  In the absence of such
   approved agreement, Buyer will make electric power  available to the Facility
   at rates and pursuant to terms and conditions on file with the MPUC.
   
          3.8  WEST ENFIELD.  On the Closing Date, there shall have been
   consummated in accordance with the West Enfield Purchase Agreement, the sale
   to the Buyer of all right, title and interest of Babcock-Ultrapower West
   Enfield in and to the Power Purchase Agreement, dated as of August 13, 1984,
   as amended to date, regarding the wood-fired small power production facility
   located in West Enfield, Maine.
   
          3.9  NO LITIGATION.  No litigation whose subject matter relates to
   any of the transactions contemplated by this Agreement shall be pending or
   threatened before any court or regulatory agency the outcome of which, in the
   reasonable opinion of Seller, could materially adversely affect the ability
   of Seller to consummate such transactions.
   
          3.10  SCHEDULE 6.3(B).  Any claims under the Power Purchase
   Agreement which Buyer shall have proposed to add to Schedule 6.3(b) after the
   Underwriting Date shall be reasonably satisfactory to Seller.

   by general principles of equity, regardless of whether such equitable
   principles are considered in a proceeding at law or in equity.

                                  ARTICLE 6
                          MISCELLANEOUS PROVISIONS
   
          6.1  TRANSACTION COSTS.  (a) Buyer shall be responsible for all
   out-of-pocket costs and expenses incurred by or on behalf of Buyer in
   connection with this Agreement, including the fees and costs of its counsel,
   and shall also be responsible for fees and costs of counsel to Seller
   reasonably incurred in connection with this Agreement and the transactions
   contemplated hereby and of counsel to the Agent and the Banks (to the extent
   that Seller determines it is responsible for such fees and costs under the
   Loan Agreement and the Security Documents) incurred in connection with this
   Agreement and the transactions contemplated hereby, in each case whether or
   not the Closing occurs.  In addition, Buyer shall be responsible for the
   travel expenses and out-of-pocket costs of Seller and each partner of Seller
   incurred in connection with this Agreement and the transactions contemplated
   hereby to the extent such costs exceed $15,000, whether or not the Closing
   occurs.  Buyer shall also be responsible for all amendment, prepayment,
   breakage, termination, up-front, commitment or other Bank fees or costs or
   expenses payable in connection with the payment of the obligations of the
   Seller under the Loan Agreement as of the Escrow Release Date and the
   incurrence by Buyer of new debt in connection with the transactions
   contemplated hereby.
   
          (b)  This obligation shall survive the Closing or any termination
   of this Agreement, and Buyer shall pay such fees, costs and expenses (i)
   within 15 days after receipt of invoices submitted to Buyer by Seller
   (together with such supporting data in reasonable detail and such supporting
   documentation as may be reasonably available to Seller) as such fees, costs
   and expenses are incurred, and (ii) at the Closing to the extent they are
   known and are the subject of invoices provided to Buyer pursuant to Section
   1.4(a)(iv) hereof.
   
          6.2  TERMINATION.  This Agreement may be terminated at any time by
   the mutual agreement of Seller and Buyer, and will terminate at 12:01 A.M.
   (New York time) on September 16, 1995 unless extended by mutual agreement of
   Seller and Buyer.
   
          6.3  SURVIVAL.  (a)  All covenants, agreements, representations,
   and warranties made by the parties to this Agreement or in any agreement,
   document, or instrument executed and delivered pursuant hereto or in
   connection with the transactions contemplated hereby shall survive the
   Closing, to the extent of and in accordance with their terms.
   
          (b)  From and after the Closing Date and notwithstanding the
   consummation of the sale described in Section 1.1 hereof, all rights of Buyer
   and Seller against each other under the Power Purchase Agreement in respect
   of any claim of either Buyer or Seller which is described in Schedule 6.3(b)
   hereof, or any claim arising during the period from the date hereof until the
   Closing Date and which shall be described in Schedule 6.3(b) hereof as
   amended as of the Closing Date, shall survive and be preserved for further
   action by Buyer or Seller in accordance with the terms of the Power Purchase
   Agreement as in effect on the date hereof and applicable law.  
   
          6.4  TAX INDEMNIFICATION.  (a) Buyer hereby agrees to indemnify and
   hold Seller and each partner of Seller (each, a "Tax-Indemnified Party")
   harmless on an After-Tax Basis from and against any and all taxes, fees,
   duties, impost, levies or charges of whatsoever nature (other than taxes of
   general applicability based on income) imposed by the State of Maine or any
   political subdivision thereof or any taxing authority of such State or
   political subdivision and all interest, penalties or similar liabilities with
   respect thereto (any such amounts, "Taxes") solely as a result of any payment
   made or to be made by Buyer to Seller pursuant to this Agreement or as a
   result of the purchase and sale of Seller's right, title and interest in and
   to the Power Purchase Agreement as contemplated by this Agreement but only to
   the extent such Taxes are imposed as a result of a Change in Law after the
   date of this Agreement.  Buyer agrees to pay (or reimburse such Tax-
   Indemnified Party for payment of) any and all Taxes within 45 days of the
   date on which such Tax-Indemnified Party delivers to Buyer the documentation
   required by the immediately succeeding paragraph. 
   
          Each Tax-Indemnified Party will (i) notify Buyer in writing within
   five business days of such Tax-Indemnified Party's receipt of an assessment,
   notice or request for payment of any such Tax from a taxing authority, and
   (ii) supply to Buyer not less than twenty business days in advance of the due
   date therefor calculations, documentation and forms of returns (or, at the
   option of such Indemnified Party, pertinent portions of or excerpts from such
   returns) demonstrating the nature, amount and calculation of any Tax which
   such Tax-Indemnified Party believes Buyer is obligated to pay pursuant to
   this Section.  In no event will Buyer be obligated to pay interest, penalties
   or late charges due as a result of a Tax-Indemnified Party's failure to file
   returns or make Tax payments within the time periods required by law unless
   such failure is the result of the action or inaction of Buyer.  Failure of a
   Tax-Indemnified Party to provide any notice or other item to Buyer as
   described in this paragraph by the time specified in this or the immediately
   succeeding paragraph shall not, however, affect such Tax-Indemnified Party's
   right to indemnification as provided in the first paragraph of this Section
   6.4(a).
   
          Each Tax-Indemnified Party will promptly notify Buyer of any event
   which such Tax-Indemnified Party  believes constitutes or may constitute a
   Change of Law promptly after becoming aware thereof.  Buyer may, at its
   option, require such Tax-Indemnified Party, with funds provided by Buyer, to
   make any payment of Tax pursuant to this Section under protest and may at
   Buyer's sole expense contest the assessment or calculation of such Tax before
   the relevant taxing authority.  Each Tax-Indemnified Party agrees to Buyer
   exercising direction and control of any such protest and any related
   proceeding, and will provide reasonable cooperation at Buyer's request and
   sole expense in the conduct thereof.
   
          (b)  For purposes of Section 6.4(a) above, (i) "Change in Law"
   shall mean any finally adopted change in law, rule or regulation, or official
   published interpretation thereof in each instance, and (ii) "After-Tax Basis"
   shall mean on a basis such that any payment required to be paid on such basis
   shall, if necessary, be supplemented by a further payment so that the sum of
   the two payments, after deduction of all taxes, penalties, fines, interest
   and other charges resulting from the receipt (actual or constructive) of such
   payments imposed by or under any Federal, state or local governmental
   authority in the United States or subdivision or any taxing authority of any
   thereof (assuming for this purpose that each Tax-Indemnified Party is a tax-
   paying entity in the State of Maine subject to the maximum applicable
   corporate income tax rates then in effect), and after taking into account all
   related tax savings (whether by deduction, credit or otherwise) actually
   realized as a result of such payments or the event or circumstance giving
   rise thereto, shall be equal to the payment so required.
   
          (c)  Each Tax-Indemnified Party agrees not to actively support the
   adoption of any Change in Law to which the indemnification contained in this
   Section 6.4 would apply and further agrees that none of its affiliates shall
   do so.  In addition, each partner of Seller agrees that at the request and at
   the expense of Buyer it will use reasonable efforts to assist in any
   challenge to any such Change in Law.
   
          6.5  GENERAL INDEMNIFICATION BY BUYER.  Buyer shall defend,
   indemnify and hold Seller, each partner thereof, and each partner's
   directors, officers, employees, agents, attorneys, and affiliates (each, a
   "Seller Indemnified Party") harmless at all times against and in respect of
   any claim, action, loss, cost, expense, liability, penalty or interest, or
   damage (collectively, "Damages") suffered or incurred by such Seller
   Indemnified Party, and all other costs and expenses incurred by such Seller
   Indemnified Party in necessary investigation or, after notice to Buyer of its
   intent to do so, in attempting to avoid or oppose the imposition thereof,
   arising out of, relating to, or resulting from, (i) any breach of any
   representation, warranty, covenant, or agreement made by Buyer in this
   Agreement, or in any agreement, document, or instrument executed and
   delivered pursuant to or in connection with the transactions contemplated
   hereby or thereby; or (ii) the non-performance or malperformance of any
   obligation to be performed on the part of Buyer under this Agreement or in
   any agreement (including, without limitation, any agreement entered into
   pursuant to Section 1.8 hereof), document or instrument executed and
   delivered pursuant hereto or in connection with the transactions contemplated
   hereby or thereby; PROVIDED that Buyer shall not be obligated to indemnify
   any Seller Indemnified Party for any Damages suffered or incurred by such
   Seller Indemnified Party as a result of such Seller Indemnified Party's gross
   negligence or willful misconduct.
   
          6.6  GENERAL INDEMNIFICATION BY SELLER.  Seller shall defend,
   indemnify and hold Buyer, and each of Buyer's directors, officers, employees,
   agents, attorneys, and affiliates (each, a "Buyer Indemnified Party")
   harmless at all times against and in respect of any Damages suffered or
   incurred by such Buyer Indemnified Party, and all other costs and expenses
   incurred by such Buyer Indemnified Party in necessary investigation or, after
   notice to Seller of its intent to do so, in attempting to avoid or oppose the
   imposition thereof, arising out of, relating to, or resulting from, (i) any
   breach of any representation, warranty, covenant, or agreement made by Seller
   in this Agreement, or in any agreement, document, or instrument executed and
   delivered pursuant to or in connection with the transactions contemplated
   hereby or thereby; or (ii) the non-performance or malperformance of any
   obligation to be performed on the part of Seller under this Agreement or in
   any agreement, document or instrument executed and delivered pursuant hereto
   or in connection with the transactions contemplated hereby or thereby;
   PROVIDED that Seller shall not be required to indemnify any Buyer Indemnified
   Party for any Damages suffered or incurred by such Buyer Indemnified Party as
   a result of such Buyer Indemnified Party's gross negligence or willful
   misconduct.
   
          6.7  DEFENSE AGAINST ASSERTED CLAIMS; LIMITATIONS.  (a)  If any
   claim or assertion for Damages is made or asserted against any Seller
   Indemnified Party or Buyer Indemnified Party, as applicable, as provided in
   Section 6.5 or 6.6, such Seller Indemnified Party or Buyer Indemnified Party
   (each hereinafter referred to as an "Indemnified Party") shall with
   reasonable promptness give to the other party (the "Indemnifying Party")
   written notice of the claim or assertion for Damages and request the
   Indemnifying Party to defend the same.  The Indemnifying Party shall, at its
   expense, assume the defense of such claim or assertion with counsel
   reasonably satisfactory to the Indemnified Party.  The Indemnified Party
   shall have the right to employ separate counsel in any such action and to
   participate in the defense thereof, but the fees and expenses of such
   separate counsel shall be at the expense of the Indemnified Party unless (i)
   the engagement of such counsel has been specifically authorized by the
   Indemnifying Party in writing, (ii) the Indemnifying Party has failed to
   assume the defense of such claim or assertion within ten (10) days after
   being notified of such claim, (iii) the named parties to such action
   (including any impleaded parties) include both the Indemnifying Party and the
   Indemnified Party, and the Indemnified Party shall have reasonably concluded
   that there may be one or more legal defenses available to the Indemnified
   Party which are different from or in addition to those available to the
   Indemnifying Party, or (iv) such action involves a criminal claim against
   such Indemnified Party.  In the event the conditions set forth in clause
   (iii) of the preceding sentence are met, the Indemnifying Party shall not
   have the right to assume the defense of such action on behalf of the
   Indemnified Party as to such legal defenses available to the Indemnified
   Party which are different from or in addition to those available to the
   Indemnifying Party, but shall indemnify the Indemnified Party against all
   litigation expenses (including reasonable fees of counsel) in connection with
   such defenses.  The indemnification to which this Section 6.7 relates shall
   be made by periodic payments of the amount thereof during the course of the
   investigation or defense, as and when bills are received (together with such
   supporting data in reasonable detail and such supporting documentation as may
   be reasonably available to the Indemnified Party) or loss, damage, liability,
   cost, or expense is incurred; PROVIDED, that no settlement or compromise of
   any claim asserted or action commenced in respect of which the Indemnifying
   Party will be liable in accordance with its indemnity under this Agreement
   shall give rise to liability of such Indemnifying Party unless such
   Indemnifying Party shall have been notified in writing of the proposed
   settlement or compromise and shall have consented in writing thereto, which
   consent shall not be unreasonably withheld so long as any claims which have
   been or may be asserted against the Indemnifying Party in such action or any
   related or future action are to be released with prejudice in connection with
   such settlement or compromise, it being understood, however, that in the
   event the Indemnifying Party unreasonably withholds its consent to a
   settlement or compromise as to which it has agreed above that such consent
   shall not be unreasonably withheld, the Indemnified Party may proceed to
   consummate such settlement or compromise without the consent of the
   Indemnifying Party and may pursue its indemnification claims hereunder
   against the Indemnifying Party as provided herein in respect of the cost of
   such settlement or compromise.  Buyer and Seller will cooperate with each
   other and shall take reasonable measures to obtain the cooperation of
   Seller's Indemnified Parties and Buyer's Indemnified Parties, as applicable,
   in the defense of any action and the relevant records of each shall be
   available to the other with respect to such defense.
   
          (b)  In no event shall either party be liable to any Indemnified
   Party (as defined in Section 6.7) for any consequential, special, indirect or
   incidental damages, or loss of profits, cost of money, claims of customers or
   claims of financiers, or any amounts in settlement thereof, howsoever the
   same may be caused, in connection with any claim arising under this Agreement
   except to the extent any of the foregoing are included in a third party claim
   against a Seller Indemnified Party or Buyer Indemnified Party, as the case
   may be, to which the provisions of Section 6.5 or 6.6 apply.  In addition,
   each Seller Indemnified Party and each Buyer Indemnified Party shall use
   reasonable efforts to mitigate any Damages which may be the subject of an
   indemnification claim by it pursuant to Section 6.5 or 6.6 hereof, as
   applicable.
   
          6.8  CONDUCT PRIOR TO CLOSING.  During the period from the date of
   this Agreement to the Closing Date, (i) Buyer shall confer on a regular and
   frequent basis with one or more representatives of Seller to report on the
   status of the various conditions set forth in Article 2 hereof, (ii) Seller

   Irvine, California  92714
   
   Ladies and Gentlemen:
   
          I am General Counsel and Corporate Clerk of Bangor Hydro-Electric
   Company ("Buyer"), a Maine corporation, and have acted as its counsel in
   connection with the execution and delivery of the Purchase Agreement dated as
   of March 31, 1995 (the "Agreement") by and between Babcock-Ultrapower
   Jonesboro ("Seller"), a joint venture formed as a California general
   partnership, and Buyer relating to the Power Purchase Agreement, dated as of
   August 13, 1984, as amended, by and between Seller and Buyer.  All
   capitalized terms used herein and not otherwise defined shall have the
   respective meanings ascribed to such terms in the Agreement.
   
          In rendering this opinion, I have assumed the genuineness of all
   signatures, the authenticity of all documents submitted to me as originals
   and the conformity to authentic original documents of all documents submitted
   to me as certified, conformed or photostatic copies.
   
          I have examined and relied upon such documents, corporate records,
   certificates of corporate officers and representatives and other instruments
   and legal matters as I have deemed necessary for the purposes of the opinions
   expressed herein.
   
          Based upon the foregoing, it is my opinion that:
   
          1.  Buyer is a corporation duly organized, validly existing and in
   good standing under the laws of the State of Maine.  Buyer has full corporate
   authority and power to enter into the Agreement, the Post-PPA Agreements and
   the Assignment and to perform its obligations thereunder.
   
          2.  Except for such approvals with respect to the Post-PPA
   Agreements as are set forth in the Agreement, no consent, order,
   authorization, waiver, approval or any other action by, or registration,
   declaration or filing with, any person, board or body, public or private, is
   required for Buyer to enter into the Agreement, the Post-PPA Agreements or
   the Assignment or for Buyer to perform, and to be legally bound to perform,
   its obligations thereunder.
   
          3.  The Agreement, the Post-PPA Agreements and the Assignment have
   been duly and validly authorized by all requisite action on the part of
   Buyer, have been duly and validly executed and delivered by Buyer and,
   assuming due authorization, execution and delivery by Seller, constitute the
   legal, valid and binding obligations of Buyer, enforceable against it in
   accordance with their respective terms, except as enforceability may be
   limited by bankruptcy, insolvency or other similar laws applicable to
   creditors' rights generally and except as the availability of any particular
   remedy may be limited by general principles of equity, regardless of whether
   such enforceability is considered in a proceeding in equity or at law, and
   subject in the case of the Post-PPA Agreements to the receipt of such
   approvals as are described in Sections 3.4 through 3.7 of the Agreement.
   
          4.  The execution, delivery and performance of the Agreement, the
   Post-PPA Agreements and the Assignment will not result in any violation of
   the articles of incorporation or by-laws of Buyer or (subject in the case of
   the Post-PPA Agreements to the receipt of such approvals as are described in
   Sections 3.4 through 3.7 of the Agreement) any existing statute, law,
   governmental rule, regulation, decree or order applicable to Buyer or its
   properties, or contravene the provisions of or constitute a default under any
   material agreement, indenture, mortgage, lease or other instrument to which
   it or its property is or may be bound.  
   
          5.  There is no action, suit, proceeding or investigation at law or
   in equity or by or before any court or administrative agency pending or, to
   the best of my knowledge threatened against or affecting Buyer which
   questions the validity of the Agreement, the Post-PPA Agreements or the
   Assignment which, individually or in the aggregate, would have a material
   adverse effect upon the ability of Buyer to enter into and carry out its
   obligations under the Agreement, the Post-PPA Agreements or the Assignment.
   
          I am a member of the Bar of the State of Maine and express no
   opinion as to any laws other than the laws of the State of Maine and the
   federal laws of the United States.
   
          I am furnishing this opinion to you solely for your benefit in
   connection with the transactions contemplated by the Agreement and this
   opinion is not to be used, circulated, quoted or otherwise referred to for
   any other purpose without my prior written approval in each instance.
   
                              Very truly yours,
      
                                                                    EXHIBIT C
   
   
   
   
   
          Counsel to Seller and counsel to each partner of Seller shall
   deliver opinions, dated the Closing Date, to the effect that:
   
          1.  Seller is a general partnership duly organized, validly
   existing and in good standing under the laws of the State of California. 
   Seller is fully authorized and empowered to enter into the Agreement, the
   Post-PPA Agreements and the Assignment and to perform its obligations
   thereunder.
   
          2.  No consent, order, authorization, waiver, approval or any other
   action by, or registration, declaration or filing with, any person, board or
   body, public or private, is required for Seller to enter into the Agreement,
   the Post-PPA Agreements or the Assignment for Seller to perform, and to be
   legally bound to perform, its obligations thereunder.
   
          3.  The Agreement, the Post-PPA Agreements and the Assignment have
   been duly and validly authorized by all requisite action on the part of
   Seller, have been duly and validly executed and delivered by Seller and
   constitute the legal, valid and binding obligation of Seller, enforceable
   against it in accordance with their respective terms, except as
   enforceability may be limited by bankruptcy, insolvency or other similar laws
   applicable to creditors' rights generally and except as the availability of
   any particular remedy may be limited by general principles of equity,
   regardless of whether such enforceability is considered in a proceeding in
   equity or at law.
   
          4.  The execution, delivery and performance of the Agreement, the
   Post-PPA Agreements and the Assignment will not result in any violation of
   the partnership agreement of Seller or any existing statute, law,
   governmental rule, regulation, decree or order applicable to Seller or its
   properties, or contravene the provisions of or constitute a default under any
   material agreement, indenture, mortgage, lease or other instrument to which
   it or its property is or may be bound.  
   
          5.  There is no action, suit, proceeding or investigation at law or
   in equity or by or before any court or administrative agency pending or, to
   the best of our knowledge threatened against or affecting Seller which
   questions the validity of the Agreement, the Post-PPA Agreements or the
   Assignment which, individually or in the aggregate, would have a material
   adverse effect upon the ability of Seller to enter into and carry out its
   obligations under the Agreement, the Post-PPA Agreements or the Assignment.

                               DISPUTED ISSUES
                             Jonesboro Facility
   
   
   METERING ISSUE
   
   
   Babcock-Ultrapower Jonesboro contends that the facility has experienced high
   purchased electricity charges based on inaccurate usage readings from a
   Bangor Hydro meter located at the Jonesboro substation.  Extensive system
   checking and technical analysis, conducted by Bangor Hydro, Babcock-
   Ultrapower Jonesboro, and independent consultants, has demonstrated that the
   plant metering has been affected by harmonics in the Bangor Hydro system. 
   These harmonics have caused imbalances in the system distribution lines that
   are improperly registered by Bangor Hydro's meter as electric usage at the
   facility.  In January 1994 Babcock-Ultrapower Jonesboro, as a customer,
   notified Bangor Hydro of the alleged problem and the Partnership's concern
   about excessive past billings for electric usage and the potential for
   ongoing excessive electric charges if the situation was not corrected. 
   Despite several follow up requests and the acknowledgement by Bangor Hydro
   technicians that a problem exists, a solution has not been implemented to
   date, nor have prior overbillings been corrected.
   
   
   OCTOBER 1994 CAPACITY AND 
   ENERGY BILLINGS AND 1994 BONUS BILLINGS
   
   
   The facility completed its scheduled 1994 two-week maintenance outage a day
   and a half early and, as was the practice in the past, called Bangor Hydro
   for a dispatch order to either begin firm generation or curtail generation. 
   The facility was instructed to curtail generation and received
   acknowledgments from the Bangor Dispatch Operators that the units were
   accepted back as available for service.
   
   The facility responded to these dispatch orders and Babcock-Ultrapower
   expected to receive decremental energy payments for the period commencing
   with Bangor's dispatch order; however, Bangor Hydro refused to pay the total
   invoiced amounts, claiming that a mandatory full two-week outage was required
   and that no decremental payments were due until this period was completed.
   
   Babcock-Ultrapower contends that the maintenance periods were terminated by
   Bangor Hydro's dispatch orders, and that these orders were to be relied upon
   based on past practices and actions of Bangor Hydro.
   
   The availability of decremental energy during this period also affects
   Babcock-Ultrapower's performance payment under the 1994 Bonus Billing.
