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 agrees to provide reasonable cooperation to Buyer in connection with the possible minimization of the amounts payable pursuant to Section 1.4(a)(iii) hereof, and (iii) promptly upon learning thereof, each of Buyer and Seller shall notify the other of any breach of any representation or warranty set forth in Section 4 or Section 5 hereof. 6.9 NOTICES.

Power 6 Incorporated 2030 Main Street, 12th Floor 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. 6. Seller is the sole owner of the Interest (as defined in the Assignment) conveyed under the Assignment and such Interest of the Seller is free and clear of all liens, security interests, claims or encumbrances whatsoever. PURCHASE AGREEMENT Schedule 6.3(b) 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.
