. (a) The Company has furnished to the Purchaser the Company's financial statements for each of its fiscal years ended December 31, 1997, 1998, 1999 and 2000, containing balance sheets as at the end of such fiscal years and the related statements of earnings, retained earnings and cash flows the Company for such fiscal years, as certified by Grant Thornton, independent certified public accountants.

(b) Subject to any qualifications set forth in the accompanying reports of independent certified public accountants, all such financial statements are complete and correct (subject, in the case of such unaudited financial statements, to year-end and audit adjustments) and have been prepared in accordance with generally accepted accounting principles applied on a consistent basis throughout the periods covered thereby. Such balance sheets (together with the pertinent notes thereto) fairly present the financial condition of the Company as at the respective dates indicated, and in each case reflect all known liabilities, contingent or otherwise, at such dates, all in accordance with generally accepted accounting principles, and such statements of earnings, retained earnings and cash flows fairly present the results of the operations of the Company for the respective periods indicated.

Section 5.7. Changes; Etc

. Since December 31, 2000: (a) except as disclosed in the reports on Forms 10-K and 10-Q filed by Unitil Corporation ("Unitil"), owner of all of the outstanding common stock of the Company, with the Securities and Exchange Commission under the Securities Exchange Act of 1934, as amended (the "10-K and 10-Q Reports"), there has been no material adverse change in the assets, liabilities or financial condition of the Company from that reflected in the balance sheet as at December 31, 2000 referred to in Section 5.6 or otherwise previously disclosed in writing, other than changes in the ordinary course of business; (b) neither the business, operations or affairs of the Company nor any of its properties or assets have been materially adversely affected by any occurrence or development (whether or not insured against) except as disclosed in the 10-K or the 10-Q Reports or otherwise previously disclosed in writing; and (c), except as otherwise disclosed in writing, the Company has not, prior to the Closing Date, directly or indirectly, declared, paid or made any dividend or distribution on or on account of any shares of capital stock of the Company or any redemption, retirement, purchase or other acquisition of any shares of capital stock of the Company, or agreed to do so, except for the payment of regular cash dividends on its Cumulative Preferred Stock and purchases of Cumulative Preferred Stock under applicable sinking fund provisions.

The federal income tax liability of the Company has been finally determined by the Internal Revenue Service and satisfied through the fiscal year ended December 31, 1993. The charges, accruals and reserves on the books of the Company in respect of income taxes for all fiscal periods are adequate in the opinion of the Company and, except as disclosed in the 10-K and the 10-Q Reports, the Company knows of no unpaid assessment for additional income taxes for any fiscal period or of any basis therefor.

Section 5.9. Title to Properties

. (a) The Company has good and marketable title to all the real property and a good and valid ownership interest in all the other assets reflected in the most recent balance sheet referred to in Section 5.6 or subsequently acquired, other than real property and other assets subsequently sold or otherwise disposed of in the ordinary course of business, subject in each case to no Liens except (i) the Lien created by the Indenture and (ii) other Liens permitted by the Indenture which do not materially detract from the value of the respective properties subject thereto or materially impair the operations of the Company.

(b) The Properties specifically to be included as mortgaged as set forth in the granting clauses of the Indenture (including the granting clauses included in the Eleventh Supplemental Indenture), other than properties released from the lien thereof pursuant to the terms thereof, are owned by the Company, located in New Hampshire and constitute substantially all of the Property of the Company except certain Property which is not "public utility property" (as defined in Section  10.04A of the Indenture), which Property has heretofore been duly released from the lien of the Indenture pursuant to Section 10.04A thereof (the "Excepted Property"). All of the real estate and other Property which is reflected in the balance sheet of the Company as of December 31, 2000 referred to in Section 5.6, and all of the rights of way, easements, grants, permits, privileges, franchises and other rights necessary to the operation of said Property, are subject to the Indenture as a first lien thereon (subject only to Liens permitted by the Indenture) except properties expressly excluded from said lien of the Indenture by the provisions thereof (including the Excepted Property).

Section 5.11. Compliance with Other Instruments, Etc

Section 5.12. ERISA

. (a) The Company and each ERISA Affiliate have operated and administered each Plan in compliance with all applicable laws except for such instances of noncompliance as have not resulted in and could not reasonably be expected to result in a Material Adverse Effect. Neither the Company nor any ERISA Affiliate has incurred any liability pursuant to Title I or IV of ERISA or the penalty or excise tax provisions of the Code relating to employee benefit plans (as defined in Section 3 of ERISA), and no event, transaction or condition has occurred or exists that could reasonably be expected to result in the incurrence of any such liability by the Company or any ERISA Affiliate, or in the imposition of any lien on any of the rights, properties or assets of the Company or any ERISA Affiliate, in either case pursuant to Title I or IV of ERISA or to such penalty or excise tax provisions or to Section 401(a)(29) or 412 of the Code, other than such liabilities or liens as would not be individually or in the aggregate Material.

(b) The present value of the aggregate benefit liabilities under each of the Plans (other than Multiemployer Plans), determined as of the end of such Plan's most recently ended plan year on the basis of the actuarial assumptions specified for funding purposes in such Plan's most recent actuarial valuation report, did not exceed the aggregate current value of the assets of such Plan allocable to such benefit liabilities. The term "benefit liabilities" has the meaning specified in Section 4001 of ERISA and the terms "current value" and "present value" have the meaning specified in Section 3 of ERISA.

(d) The expected post-retirement benefit obligation (determined as of the last day of the Company's most recently ended fiscal year in accordance with Financial Accounting Standards Board Statement No. 106, without regard to liabilities attributable to continuation coverage mandated by section 4980B of the Code) of the Company is not Material.

(e) The execution and delivery of this Agreement and the issuance and sale of the Series K Bonds hereunder will not involve any transaction that is subject to the prohibitions of section 406 of ERISA or in connection with which a tax could be imposed pursuant to section 4975(c)(1)(A)-(D) of the Code. The representation by the Company in the first sentence of this Section 5.12(e) is made in reliance upon and subject to the accuracy of the Purchaser's representation in Section 7(b) as to the sources of the funds used to pay the purchase price of the Bonds.

The issuance and sale of the Bonds has been authorized by order of the NHPUC, which has become final and all applicable appeal periods with respect to the NHPUC order have expired. Although a post-sale filing with the SEC on Form U-6B-2 is required, the issuance and sale of the Bonds is not subject to the prior approval of the SEC under the Holding Company Act. No order, consent, approval or authorization of, or any declaration or filing with, any other governmental agency or authority is required as a condition precedent to the valid offering, issue, sale and delivery of the Bonds by the Company and the consummation by the Company of the transactions contemplated hereby.

Section 5.14. Patents; Trademarks; Etc

. The Company owns or possesses all of the patents, trademarks, service marks, trade names and copyrights, and all rights of use with respect to the foregoing, necessary for the conduct of its business as now conducted, without any known conflict with the rights of others.

. Neither the Company nor anyone authorized to act on its behalf has directly or indirectly offered or will offer the Bonds or any part thereof or any similar securities for issue or sale to, or solicited or will solicit any offer to acquire any of the same from, or has otherwise approached or negotiated or will approach or negotiate in respect thereof with anyone other than the Purchaser and not more than 124 other institutional investors. Neither the Company nor anyone authorized to act on its behalf has taken or will take any action which will subject the issuance and sale of the Bonds to the provisions of Section 5 of the Securities Act of 1933, as amended (the "Securities Act").

Section 5.16. Investment Company Act Status

. The Company is not an "investment company" or a company "controlled" by an "investment company", as such terms are defined in the Investment Company Act of 1940, as amended.

The proceeds of the sale of the Bonds will be applied as provided in Section 6. None of such proceeds will be used, directly or indirectly, for the purpose of purchasing or carrying any margin security or for the purpose of reducing or retiring any indebtedness which was originally incurred to purchase or carry a margin security or for any other purpose which might constitute the transactions contemplated hereby a "purpose credit" within the meaning of said Regulation  U, or cause this Agreement to violate Regulation U, Regulation T, Regulation X, or any other regulation of the Board of Governors of the Federal Reserve System or Section 7 of the Securities Exchange Act of 1934 (the "Exchange Act'"), each now in effect.

Section 5.18. Foreign Credit Restraints

.

Section 5.19. Disclosure

. Neither this Agreement, the financial statements referred to in Section 5.6, the 10-K and the 10-Q Reports, nor any other document, certificate or written statement furnished to the Purchaser by or on behalf of the Company in connection with the negotiation of the sale of the Bonds, contains any untrue statement of a material fact or omits to state a material fact necessary in order to make the statements contained herein and therein not misleading. There is no fact known to the Company which materially adversely affects or in the future may (so far as the Company can now reasonably foresee) materially adversely affect the business, operations, affairs or condition of the Company or its Properties or assets, which has not been set forth in this Agreement or in the other documents, certificates and written statements furnished to the Purchaser by or on behalf of the Company prior to the date of this Agreement in connection with the transactions contemplated hereby.

Section 5.21. No Defaults

. No Default or Event of Default has occurred and is continuing. The Company is not in default in the payment of principal or interest on any Indebtedness and is not in default under any instrument or instruments or agreements under and subject to which any Indebtedness has been issued and no event has occurred and is continuing under the provisions of any such instrument or agreement which with the lapse of time or the giving of notice, or both, would constitute an event of default thereunder.

Section 5.22. Compliance with Environmental Laws

. Except as disclosed in the 10-K or the 10-Q Reports, to the best of the Company's knowledge it is not in violation of any applicable Federal, state, or local laws, statutes, rules, regulations or ordinances relating to public health, safety or the environment, including, without limitation, relating to releases, discharges, emissions or disposals to air, water, land or ground water, to the withdrawal or use of ground water, to the use, handling or disposal of polychlorinated biphenyls (PCBs), asbestos or urea formaldehyde, to the treatment, storage, disposal or management of hazardous substances (including, without limitation, petroleum, crude oil or any fraction thereof, or other hydrocarbons), pollutants or contaminants, to exposure to toxic, hazardous or other controlled, prohibited or regulated substances which violation could have a material adverse effect on the business, prospects, profits, properties or condition (financial or otherwise) of the Company. Except as disclosed in the 10-K or the 10-Q Reports, the Company does not know of any liability or class of liability of the Company under the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended (42 U.S.C.

The acquisition of any of the Bonds by the Purchaser shall constitute the Purchaser's reaffirmation of such representation, and it is understood that in making the representations contained in Sections 5.12(e) and 5.15, the Company is relying, to the extent applicable, on the Purchaser's representation in this Section 7.

(b) The Purchaser represents that at least one of the following statements is an accurate representation as to each source of funds (a "Source") to be used by the Purchaser to pay the purchase price of the Series K Bonds to be purchased by the Purchaser hereunder:

(iii) the Source constitutes assets of an "investment fund" (within the meaning of Part V of the QPAM Exemption) managed by a "qualified professional asset manager" or "QPAM" (within the meaning of Part V of the QPAM Exemption), no employee benefit plan's assets that are included in such investment fund, when combined with the assets of all other employee benefit plans established or maintained by the same employer or by an affiliate (within the meaning of Section V(c)(1) of the QPAM Exemption) of such employer or by the same employee organization and managed by such QPAM, exceed 20% of the total client assets managed by such QPAM, the conditions of Part I(c) and (g) of the QPAM Exemption are satisfied, neither the QPAM nor a Person controlling or controlled by the QPAM (applying the definition of "control" in Section V(e) of the QPAM Exemption) owns a 5% or more interest in the Company and (A) the identity of such QPAM and (B)  the names of all employee benefit plans whose assets are included in such investment fund have been disclosed to the Company in writing pursuant to this paragraph (b)(iii); or

Concord Electric Company

Ladies and Gentlemen:

We have acted as your special counsel in connection with your purchase on this date of $7,500,000 principal amount of 8.00% First Mortgage Bonds, Series K, due May 1, 2031 (the "Bonds"), of Concord Electric Company, a New Hampshire corporation (the "Company"), pursuant to the Bond Purchase Agreement (the "Agreement") between you and the Company, dated as of April 20, 2001. The Bonds are issued under the Indenture of Mortgage and Deed of Trust dated as of July 15, 1958 (the "Original Indenture") from the Company to State Street Bank and Trust Company (as successor to Old Colony Trust Company), as Trustee (the "Trustee"), as heretofore supplemented and amended by a First Supplemental Indenture dated as of January 15, 1968, a Second Supplemental Indenture dated as of November 15, 1971, a Third Supplemental Indenture dated as of July 1, 1975, a Fourth Supplemental Indenture dated as of March 28, 1984, a Fifth Supplemental Indenture dated as of June 1, 1984, a Sixth Supplemental Indenture dated as of October 29, 1987, a Seventh Supplemental Indenture dated as of August 29, 1991, an Eighth Supplemental Indenture dated as of October 14, 1994, a Ninth Supplemental Indenture dated as of September 1, 1998, a Tenth Supplemental Indenture dated as of January 15, 2001 and as supplemented by an Eleventh Supplemental Indenture dated as of April 20, 2001 (the "Eleventh Supplemental Indenture"). The Original Indenture as so supplemented and amended is hereinafter referred to as the "Indenture". Capitalized terms used herein and not otherwise defined, shall have the meanings set forth in the Agreement.

In that connection, we have examined the following:

(a) The Agreement;

(b) The Indenture;

(c) A copy of the Articles of Association of the Company and all amendments thereto certified by the Secretary of the Company and the Certificates of (i) the Secretary of State of the State of New Hampshire evidencing the corporate existence of the Company and (ii) the Treasurer of the Company certifying to the Company's payment of all state and local taxes (collectively, the "Good Standing Certificates");

(d) A copy of the By-laws of the Company, as amended to the date hereof, and a copy of the resolutions adopted by the Board of Directors of the Company with respect to the authorization of the Agreement, the Eleventh Supplemental Indenture, the issuance, sale and delivery of the Bonds and related matters, each as certified by the Secretary of the Company;

(e) The opinion of LeBoeuf, Lamb, Greene & MacRae, L.L.P., counsel to the Company, dated the date hereof and delivered responsive to Section 4.5 of the Agreement;

(f) The executed Bonds delivered on the date hereof;

(g) The order of the New Hampshire Public Utilities Commission dated March 23, 2001, authorizing the issue and sale of the Bonds;

(h) Such certificates of officers of the Company and of public officials as we have deemed necessary to give the opinions hereinafter expressed; and

(i) Such other documents and matters of law as we have deemed necessary to give the opinions hereinafter expressed.

We believe that the opinion referred to in clause (e) above including the attachments referred to therein is satisfactory in scope and form and that you and we are justified in relying thereon. Our opinion as to matters referred to in paragraph 1 below is based solely upon an examination of the Articles of Association and the By-laws of the Company, the Good Standing Certificates and the general business corporation law of the State of New Hampshire. We have also relied, as to certain factual matters, upon appropriate certificates of public officials and officers of the Company and upon representations of the Company and you delivered in connection with the issuance and sale of the Bonds.

Based upon the foregoing, we are of the opinion that:

1. The Company is a corporation, validly existing and in good standing under the laws of the State of New Hampshire and has the corporate power and the corporate authority to execute and deliver the Agreement, the Eleventh Supplemental Indenture and the Bonds.

2. The Eleventh Supplemental Indenture has been duly authorized by all necessary corporate action on the part of the Company, has been duly executed and delivered by the Company and the Indenture constitutes the legal, valid and binding contract of the Company enforceable in accordance with its terms, except as such terms may be limited by the laws affecting the remedies to enforce the security provided by the Indenture, which laws do not, in our opinion, make inadequate the remedies necessary for the realization of the benefits of such security, and except as such terms are subject to bankruptcy, insolvency, fraudulent conveyance and similar laws affecting creditors' rights generally, and general principles of equity (regardless of whether the application of such principles is considered in a proceeding in equity or at law).

3. The Bonds have been duly authorized by all necessary corporate action on the part of the Company, and the Bonds being delivered on the date hereof have been duly executed and delivered by the Company and duly authenticated by the Trustee, and constitute legal, valid and binding obligations of the Company, enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent conveyance and similar laws affecting creditors' rights generally, and general principles of equity (regardless of whether the application of such principles is considered in a proceeding in equity or at law) and are entitled to the benefits and security afforded by the Indenture equally and ratably with all other bonds outstanding under the Indenture.

4. The Agreement has been duly authorized by all necessary corporate action on the part of the Company, has been duly executed and delivered by the Company and constitutes the legal, valid and binding contract of the Company, enforceable in accordance with its terms, subject to bankruptcy, insolvency, fraudulent conveyance and similar laws affecting creditors' rights generally, and general principles of equity (regardless of whether the application of such principles is considered in a proceeding in equity or at law).

5. The issuance, sale and delivery of the Bonds under the circumstances contemplated by the Agreement do not, under existing law, require the registration of the Bonds under the Securities Act of 1933, as amended, or the qualification of the Indenture under the Trust Indenture Act of 1939, as amended.

Our opinion is limited to the laws of the States of Illinois and New Hampshire and the Federal laws of the United States and we express no opinion on the laws of any other jurisdiction. We have relied upon the opinion of LeBoeuf, Lamb, Greene & MacRae, L.L.P., as to (i) all matters set forth herein which are governed by the laws of the State of New Hampshire, except for our opinion as to matters referred to in paragraph 1 above, (ii) the due authorization, execution and delivery of the Indenture including the supplemental indentures thereto other than the Eleventh Supplemental Indenture, (iii) the enforceability of the Indenture, and (iv) the title of the Company to its properties and the filing and recording of the Indenture and the lien thereof and, accordingly, all applicable assumptions, qualifications and exceptions set forth in such opinion including any certificates or other opinions upon which such opinion relies, are incorporated herein.

Respectfully submitted,

JEJenz:SKhan

Form of Opinion of
Counsel to the Company

The closing opinion of LeBoeuf, Lamb, Greene & MacRae, L.L.P., counsel to the Company, which is called for by Section 4.5 of the Bond Purchase Agreement, shall be dated the date of Closing and addressed to the Purchaser, shall be satisfactory in scope and form to the Purchaser and shall be to the effect that:

(1) The Company is a corporation validly existing and in good standing under the laws of the State of New Hampshire, has the corporate power and authority and all necessary licenses, franchises, permits and rights to issue, sell and deliver the Bonds and to carry on its business and own its Property and is duly authorized to enter into and perform the Bond Purchase Agreement and the Indenture and to issue the Bonds and to incur the Indebtedness to be evidenced thereby.

(2) The Bond Purchase Agreement has been duly authorized, executed and delivered by the Company and constitutes the legal, valid and binding agreement of the Company, enforceable in accordance with its terms, subject to any applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or similar laws affecting the rights of creditors generally from time to time in effect, and general principles of equity (regardless of whether such enforceability is considered in equity or at law).

(3) The Indenture has been duly authorized by all necessary corporate action on the part of the Company, has been duly executed and delivered by the Company and constitutes the legal, valid and binding obligation of the Company enforceable in accordance with its terms, subject to bankruptcy, insolvency, reorganization or similar laws affecting the enforcement of creditors' rights generally and applicable principles of equity, and subject and subject to the laws affecting the remedies for the enforcement of the security provided for therein, which laws do not, in our opinion, make inadequate the remedies necessary for the realization of the benefits of such security; provided that under the law of the State of New Hampshire a purchaser at a foreclosure sale of such portion of the Company's Properties as constitute a public utility would have to obtain the permission and approval of the NHPUC to engage in business as such a utility in the area in which such purchaser proposed to carry on such a utility business.

(4) The Bonds have been duly authorized by proper corporate action on the part of the Company, have been duly executed and delivered by authorized officers of the Company and constitute the legal, valid and binding obligations of the Company enforceable in accordance with their terms, subject to any applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or similar laws affecting the rights of creditors generally from time to time in effect, and general principles of equity (regardless of whether such enforceability is considered in equity or at law) and are entitled to the benefits and security afforded by the Indenture equally and ratably with all other bonds outstanding under the Indenture.

(5) The issuance, sale and delivery of the Bonds under the circumstances contemplated by the Bond Purchase Agreement are exempt from the registration requirements of the Securities Act of 1933, as amended, and do not under existing law require the registration of the Bonds under the Securities Act of 1933, as amended, or the qualification of an indenture in respect thereof under the Trust Indenture Act of 1939.

(6) The Company has full corporate power and authority and is duly authorized to conduct the activities in which it is now engaged and, to the best of our knowledge, is not required to be licensed or qualified as a foreign corporation in any jurisdiction.

(7) The issuance and sale of the Bonds and the execution, delivery and performance by the Company of the Bond Purchase Agreement and the Eleventh Supplemental Indenture do not conflict with or result in any breach of any of the provisions of, or constitute a default under or result in the creation or imposition of any Lien upon any of the Property of the Company under the provisions of the Articles of Association or By-laws of the Company or, to the best of our knowledge, any agreement or other instrument to which the Company is a party or by which the Company is bound (other than pursuant to the mortgage).

(8) The Indenture has been filed for record in all offices where such filings are necessary in order that it create a valid and effective Lien of record on the Property intended to be subject thereto, and the Indenture creates the valid, direct first Lien upon the Company's Property, real and personal, now owned or hereafter acquired, described therein, subject only to Liens permitted by the Indenture; and there is no requirement that the Indenture shall be refiled or rerecorded at any time or from time to time in order to continue or perfect the Lien thereof, except, however, that the financing statements which have been filed with the Secretary of State of New Hampshire and the Merrimack County Registry of Deeds in order to protect and preserve the Lien of the Indenture on certain of the Property intended to be subject thereto must be periodically renewed by the filing of appropriate continuation statements.

(9) The issue and sale of the Bonds have to the extent required by law been duly authorized by an order of the NHPUC, such order is in full force and effect, the applicable appeal period has expired, and no other consent, exemption, approval or authorization by any other governmental authority (including, without limitation, the SEC under the Holding Company Act) is required in connection with the execution and delivery of the Bond Purchase Agreement or the Eleventh Supplemental Indenture or the issue, sale and delivery of the Bonds except that a filing with the SEC under the Holding Company Act of a Certificate of Notification on Form U-6B-2 is required to be made by the Company within ten days after the issue and sale of the Bonds, as provided in Rule 52 under the Holding Company Act.

(10) None of the transactions contemplated in the Bond Purchase Agreement (including, without limitation thereof, the proposed use of the proceeds from the sale of the Bonds) violate Section 7 of the Securities Exchange Act of 1934, as amended, or any regulations issued pursuant thereto, including, without limitation, Regulations U, T and X of the Board of Governors of the Federal Reserve System, 12 C.F.R., Chapter II.

(11) To the best of our knowledge, without conducting a search of any dockets, there are no actions, suits, investigations or proceedings to which the Company is a party in any court or before any governmental authority which, if determined adversely to the Company, would materially and adversely affect the Company's ability to perform its obligations under the Bond Purchase Agreement, the Indenture or the Bonds; and the Company is not, to the best of our knowledge, in default with respect to any order, judgment or decree of any court or governmental authority to which it is a party or by which it is bound.

In rendering its opinion, LeBoeuf, Lamb, Greene & MacRae, L.L.P., shall be entitled to rely upon opinions of local counsel satisfactory to them and with respect to matters of fact on which such opinion is based, shall be entitled to rely on appropriate Certificates of public officials and officers of the Company.
