The Commission is requested to mail copies of all orders, notices and communications to: William S. Lamb, Esq. LeBoeuf, Lamb, Greene & MacRae, L.L.P. 125 West 55th Street New York, New York 10019

On June 9, 2000, Unitil Corporation, a New Hampshire corporation ("Unitil") and a registered holding company under the Public Utility Holding Company Act of 1935, as amended (the "Act"), and its wholly owned subsidiary companies, Concord Electric Company ("Concord"), Exeter & Hampton Electric Company ("Exeter"), Fitchburg Gas and Electric Light Company ("Fitchburg"), Unitil Power Corp. ("Unitil Power"), Unitil Realty Corp. ("Unitil Realty"), Unitil Resources, Inc. ("Unitil Resources") and Unitil Service Corp. ("Unitil Service" and, together with Concord, Exeter, Fitchburg, Unitil Power, Unitil Realty and Unitil Resources, the "Subsidiaries" or "Money Pool Participants"), received approval under the Act from the Securities and Exchange Commission (the "Commission") for the authorization and approval under Sections 6(b), 7, 9(a), 10 and 12(b) of the Act and the Rules 43, 45 and 52 thereunder with respect to (i) short-term borrowing by Unitil, (ii) short-term borrowings by Fitchburg and (iii) the continued use of the system money pool ("Money Pool") by Unitil and the Money Pool Participants, pursuant to the Cash Pooling and Loan Agreement (the "Pooling Agreement") among Unitil and the Money Pool Participants dated as of February 1, 1985, as amended, Holding Co. Act Release No. 27182 (the "Order"). The Applicants hereby file this post effective amendment to their application-declaration on Form U-1 relating to the above-referenced transactions (the "Application-Declaration") under the Act in order to increase certain authorized borrowing amounts authorized in the Order. ITEM 1. DESCRIPTION OF PROPOSED TRANSACTIONS The Applicants hereby submit this Application-Declaration for authorization and approval under Sections 6(a), 7, 9(a), 10 and 12(b) of the Act and the Rules 43, 45 and 52 thereunder to increase Unitil's authorized short-term borrowing to $35 million from $25 million. Since the Commission issued the Order, Unitil reevaluated its financial needs and determined that the Company will require authority to issue up to $35 million in short-term debt to meet its financing needs prior to the completion of its 2001 long-term financing plans. As Unitil finalized its long-term financing plans for 2001, it determined that additional borrowing authority would be required to give it the financial flexibility needed to successfully complete its upcoming financing plans. Additionally, with rising energy costs, such an increase would assist it in meeting any short-term payment timing differences that may occur in the future related to energy supply costs. Unitil's Board of Directors authorized this short-term borrowing limit of $35 million on September 29, 2000. (See Exhibit B-7) Any borrowings undertaken pursuant to this authorization will remain subject to the parameters set forth in the Order, except for the new aggregate limit of $35 million. Applicants are not requesting an increase in borrowing authority for Fitchburg. 1

A. Short-Term Borrowings by Unitil Unitil expects to use the proceeds derived from short-term bank borrowings authorized by this Commission pursuant to this application-declaration for: (i) loans or advances to Subsidiaries through the Pooling Agreement, (ii) payment of indebtedness, (iii) short-term cash needs which may arise due to payment timing differences, (iv) greater flexibility in financial planning and (iv) other general purposes. When the Commission issued the Order, Unitil had unsecured lines of credit with BankBoston, Fleet Bank New Hampshire and Citizens Bank New Hampshire; the agreements are included as Exhibits B-2, B-3 and B-4 respectively. These letters of credit and promissory notes are exemplary of forms of short-term notes proposed to be used by Unitil./1 Unitil has also amended the Pooling Agreement to allow Unitil Resources, Inc. to participate in the Money Pool, and the amended Pooling Agreement is attached as Exhibit B-1. B. Involvement with Exempt Wholesale Generators and Foreign Utility Companies The proposed transactions are not subject to Rules 53 and 54 under the Act. Neither Unitil nor any Subsidiary thereof presently has, or as a consequence of the proposed transactions will have, an interest in any exempt wholesale generator ("EWG") or foreign utility company ("FUCO"), as those terms are defined in Sections 32 and 33 of the Act, respectively. None of the proceeds from the proposed transactions will be used to acquire any securities of, or any interest in, an EWG or FUCO. Moreover, neither Unitil nor any of the Subsidiaries is, or as a consequence of the proposed transactions will become, a party to, and such entities do not and will not have any rights under, a service, sales or construction contract with any affiliated EWGs or FUCOs except in accordance with the rules and regulations promulgated by the Commission with respect thereto. Consequently, all applicable requirements of Rule 53(a)-(c) under the Act are satisfied as required by Rule 54 under the Act. ITEM 2. FEES, COMMISSIONS AND EXPENSES The fees, commissions and expenses of the Applicants expected to be paid or incurred, directly or indirectly, in connection with the transactions described above are estimated as follows: - -------- 1 Since the original notes were signed, Fleet Bank and BankBoston have merged, with Fleet Bank as the surviving entity. The previous lines of credit have also expired. Accordingly, Unitil has renegotiated its lines of credit and as of October 9, 2000 had three lines of credit: a $16 million unsecured line of credit from Fleet National Bank (attached as Exhibit B-8); a $5 million unsecured line of credit from Citizens Bank New Hampshire (attached as Exhibit B-9); and a $4 million unsecured line of credit from Sovereign Bank of New England (attached as Exhibit B-10). These newer letters of credit and promissory notes are substantively similar to the exemplary agreements provided in the approved Application-Declaration. 2

Legal fees .......................................... $5,000 Miscellaneous .......................................... $3,000 Total .......................................... $8,000 ITEM 3. APPLICABLE STATUTORY PROVISIONS Sections 6(a), 7, 9(a), 10 and 12(b) of the Act, and Rules 43, 45 and 52 thereunder, are directly applicable to this Application-Declaration. ITEM 4. REGULATORY APPROVALS No state or federal agency other than the Commission has jurisdiction with respect to any of the proposed transactions other than as described in this item. ITEM 5. PROCEDURE It is requested that the Commission issue and publish no later than November 6, 2000, the requisite notice under Rule 23 with respect to this Application-Declaration; such notice specifying December 1, 2000 as the date by which comments may be entered and the date on which an order granting and permitting the Application-Declaration to become effective may be entered by the Commission and that the Commission enter not later than December 15, 2000, an appropriate order granting and permitting this Application-Declaration to become effective. The Applicants respectfully request that appropriate and timely action be taken by the Commission in this matter. No recommended decision by a hearing officer or other responsible officer of the Commission is necessary or required in this matter. The Division of Investment Management of the Commission may assist in the preparation of the Commission's decision in this matter. There should be no thirty-day waiting period between the issuance and effective date of any order issued by the Commission in this matter, and it is respectfully requested that any such order be made effective immediately upon the entry thereof.

Securities and Exchange Commission
450 Fifth Street, N.W.

Washington, DC 20549

Sir or Madam:

     This opinion is furnished to the  Securities and Exchange  Commission  (the
"Commission")   in   connection   with  the  filing  with  the   Commission   of
Post-Effective Amendment No. 2 ("Amendment") to the  Application/Declaration  on
Form U-1 (File 70-9633) of Unitil  Corporation (the "Company"),  a New Hampshire
corporation  and  a  registered   public  utility  holding   company,   and  its
subsidiaries,  Concord  Electric  Company,  Exeter & Hampton  Electric  Company,
Unitil Power Corp.,  Unitil  Realty  Corp.,  Unitil  Resources,  Inc. and Unitil
Service Corp., each of which is a New Hampshire corporation,  and its subsidiary
Fitchburg  Gas  and  Electric  Light  Company  ("Fitchburg"),   a  Massachusetts
corporation  (collectively,  the Company and its subsidiaries are referred to as
the  "Applicants")  under the Public  Utility  Holding  Company Act of 1935 (the
"Application-Declaration").  The Amendment relates to the request by the Company
for  authorization  to raise its  authorized  level of short-term  debt from $25
million to $35 million.

     We have examined originals of the Amendment and the Application-Declaration
and  originals,  or copies  certified  to our  satisfaction,  of such  corporate
records of the  Applicants,  certificates of public  officials,  certificates of
officers and  representatives  of the Applicants and other  documents as we have
deemed  it  necessary  to  require  as a  basis  for  the  opinions  hereinafter
expressed.  In  such  examination,  we  have  assumed  the  genuineness  of  all
signatures,  the authenticity of all documents  submitted to us as originals and
the  conformity to the original  documents of all  documents  submitted to us as
copies.  As to any facts material to our opinion,  we have,  when relevant facts
were  not  independently  established,  relied  upon the  aforesaid  agreements,
instruments,  certificates  and  documents.  In addition,  we have examined such
questions of law, as we considered  necessary or appropriate  for the purpose of
rendering this opinion.

     Based on the foregoing,  and subject to the final paragraph  hereof, we are
of the opinion that when the  Commission  has taken the action  requested in the
Application-Declaration:

     (1)  All  state  laws  applicable  to  the  transactions  described  in the
     Amendment have been complied with.

     (2) The Company is validly  organized and duly  existing  under the laws of
     the State of New Hampshire.

     (3) The notes to be issued to banks by the Company in  accordance  with the
     Amendment  will  each be  valid  and  binding  obligations  enforceable  in
     accordance with their respective terms, subject to bankruptcy,  insolvency,
     reorganization, moratorium or other similar laws now or hereafter in effect
     relating to  creditors'  rights  generally,  and to general  principles  of
     equity,   regardless  of  whether  such  principles  are  considered  at  a
     proceeding at law or in equity,  and further  subject to the  qualification
     that the remedy of specific  performance  and injunctive and other forms of
     equitable  relief may be subject to certain  equitable  defenses and to the
     discretion  of the  court  before  which  any  proceeding  therefor  may be
     brought.

     (4) The consummation of the transactions proposed in the Amendment will not
     violate  the legal  rights of the holders of any  securities  issued by the
     Company or Fitchburg.

     The opinions  expressed  above in respect of the approval of the short-term
borrowings  described in the Amendment are subject to the following  assumptions
or conditions:

     a. The Commission  shall have duly entered an  appropriate  order or orders
     granting and permitting  the Amendment to become  effective with respect to
     the short-term borrowings described therein.

     b. No act or event  other than as  described  herein  shall  have  occurred
     subsequent  to the date hereof,  which would change the opinions  expressed
     above.

     We  hereby  consent  to the  use  of  this  opinion  as an  exhibit  to the
Application-Declaration.

     We are not,  in this  opinion,  opining  on laws other than the laws of the
State of New Hampshire and the federal laws of the United States.

                                          Very truly yours,


                                          LeBoeuf, Lamb, Greene & MacRae, L.L.P.
