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(b), 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(b), 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.

Section 1.   Certain  Defined  Terms.

     As used in this Agreement and unless otherwise  expressly indicated herein,
the  following  terms shall have the  following  meanings  (such  meanings to be
equally applicable to both the singular and plural forms of the terms defined):

               "Advance" means an advance from the Cash Pool pursuant to Section
          3 hereof and refers to a Bank Advance or a Surplus Advance.

               "Bank Advance" means an Advance of Bank Borrowings.

               "Bank  Borrowings"  means  bank  borrowings  made by  UNITIL  and
          contributed to the Cash Pool.

               "Business  Day"  means a day of the year on which  banks  are not
          required or authorized to close in Boston, Massachusetts.

               "Cash Pool" means the pool of cash,  comprising Surplus Funds and
          Bank Borrowings, from which Advances are made.

               "Surplus   Advance"   means  an   Advance   of   Surplus   Funds.

               "Surplus Funds" means surplus funds  contributed to the Cash Pool
          by the Parties.

Section 2.  Contributions to the Cash Pool.

     Funds  contributed to the Cash Pool will be deposited in one or more common
bank deposit  accounts  established and maintained for the Cash Pool. Each Party
shall have an independent  withdrawal  authority with respect to the funds which
it has contributed to the Cash Pool and any earnings  attributable to such funds
which are not funding an outstanding Advance.

Section 3.  Advances

     Section 3.01. (a) Each Party may request Advances from the Cash Pool from
time to time  during the period  from the date hereof  until this  Agreement  is
terminated  by written  agreement of the Parties;  provided,  however,  that the
aggregate  amount of all Advances to be requested by any Party  hereunder  shall
not exceed the applicable  borrowing limits, if any, established by such Party's
Board of Directors and any regulatory  authority having  jurisdiction  over such
Party or  established  pursuant to any  agreement  binding upon such Party;  and
provided,  further,  that UNITIL  Power may not receive any  Advances  hereunder
until  specifically  authorized  to receive such  Advances by the New  Hampshire
Public Utilities Commission ("NHPUC").

     Section  3.02.  To the extent  possible,  Advances  will be made first from
Surplus Funds and second from Bank Borrowings.

     Section  3.03.  Surplus  Advances will be made on a pro rata basis from the
Surplus Funds contributed to the Cash Pool by each Party in the proportion which
each Party's  Surplus Funds in the Cash Pool bear to the total amount of Surplus
Funds in the Cash Pool.

Section 4.  Interest on Advances.

     Each Party receiving an Advance shall pay interest on the unpaid  principal
amount of such Advance to the Cash Pool from the date of such Advance until such
principal  amount shall be paid in full. The interest rate applicable on any day
to Surplus  Advances shall be the daily rate of interest  applicable to loans to
UNITIL by the bank  designated  from time to time by UNITIL as its "lead  bank".
The interest rate  applicable on any day to Bank Advances shall be calculated to
produce an aggregate interest charge on all such Bank Advances,  at a rate which
shall be uniform for all such Bank Advances,  equal to the net cost to UNITIL of
the Bank Borrowings used to fund such Bank Advances on such day.

Section 5.  Repayment of Advances.

     Each Party  receiving an Advance shall repay the  principal  amount of such
Advance to the Cash Pool, together with all interest accrued thereon, within 365
days of the  date on which  such  Advance  was  made,  unless  such day on which
payment is due is not a Business  Day, in which case such payment  shall be made
on the preceding Business Day.

Section 6.  Bank Fees.

     During the first year of this Agreement the costs of compensating balances,
commitment  fees and fees paid to banks to  maintain  bank  accounts  and credit
lines for purposes of Bank Advances shall be allocated  provisionally  among the
Parties at the discretion of UNITIL Service.  In each year thereafter such costs
and fees shall be allocated  provisionally  to each Party on a pro rata basis in
the proportion which each Party's aggregate principal amount of Advances for the
prior calendar year bore to the aggregate  principal  amount of all Advances for
such prior calendar year. Such costs and fees shall be retroactively reallocated
at the end of each  calendar  year on a pro rata basis in the  proportion  which
each Party's aggregate  principal amount of Advances for such calendar year bore
to the aggregate principal amount of all Advances for such calendar year.

Section 7.  Event of Default.

     If any Party shall generally not pay its debts as such debts become due, or
shall admit in writing its inability to pay its debts generally, or shall make a
general  assignment  for the benefit of creditors;  or any  proceeding  shall be
instituted  by or against  any Party  seeking  to  adjudicate  it a bankrupt  or
insolvent, then the other Parties may declare the unpaid principal amount of any
Advances  to such Party,  and all  interest  thereon,  to be  forthwith  due and
payable and all such amounts shall forthwith become due and payable.

Section 8.  Amendments, Waivers.

     This  Agreement  may not be modified  or amended in any  respect  except in
writing executed by the Parties.  No provision of this Agreement shall be deemed
waived  unless  such  waiver is set forth in writing  and  executed by the Party
making such waiver.

Section 9.  Legal Responsibility.

     Nothing herein  contained shall render any Party liable for the obligations
of any other Party hereunder and the rights,  obligations and liabilities of the
Parties are several in accordance  with their  respective  obligations,  and not
joint.

Section 10.  Records and Administration.

     UNITIL  Service  shall  be  responsible  for  the  administration  of  this
Agreement and for ensuring that all relationships  and arrangements  between the
Parties  hereunder are in compliance with the  authorization  and any applicable
limitations  of Report and  Supplemental  Order No. 17,343 of the NHPUC.  UNITIL
Service shall further be  responsible  for the  determination  of all applicable
interest  rates and  charges to be applied to Advances  outstanding  at any time
hereunder, shall maintain records of all Advances, interest charges and accruals
and interest and  principal  payments for  purposes  hereof,  and shall  prepare
regular reports thereof for the Parties.

Section 11.  Governing Law.

     This Agreement shall be governed by, and construed in accordance  with, the
laws of the State of New Hampshire.

     IN WITNESS  WHEREOF,  the Parties have caused this Agreement to be executed
by their respective  officers  thereunto duly  authorized,  as of the date first
above written.

                                            September 13, 2000



Mr. Mark H. Collin
Treasurer
Unitil Corporation
6 Liberty Lane West
Hampton, NH 03842-1720

Dear Mark:

     We are  pleased to advise you that Fleet  National  Bank (the  "Bank")  has
approved an unsecured line of credit in the maximum  principal amount of Sixteen
Million  Dollars   ($16,000,000)   (the  "Line")  for  Unitil  Corporation  (the
"Borrower") subject to the Bank' s periodic review.  Unless renewed or demanded,
this Line will expire on June 30, 2001 (the "Annual Review Date").

     Coinciding with the establishment of the Line, the existing $8,000,000 line
of credit,  as established via a letter agreement between the Borrower and Fleet
Bank-NH  dated July 14,  1998 and  executed  on July 30,  1998 (the  "$8,000,000
Line"),  will be  thereby  eliminated  and  terminated,  disallowing  any future
advances under the $8,000,000  Line. Also coinciding with the  establishment  of
the Line, the existing  $8,000,000  line of credit,  as established via a letter
agreement  between  the  Borrower  and  BankBoston  dated July 29, 1999 (the "BB
$8,000,000 Line"),  will be thereby  eliminated and terminated,  disallowing any
future advances under the BB $8,000,000 Line.

     The Line  shall  immediately  pay out the  outstanding  balance  under  the
$8,000,000 Line and the BB $8,000,000 Line and thereafter shall be available for
short term advances  used for working  capital and general  corporate  purposes.
This letter, together with the related Line of Credit Promissory Note of near or
even date  (collectively,  the "Loan  Documents"),  shall serve as our agreement
concerning the terms and conditions of the Borrower's borrowing under the Line.

     Advances hereunder or renewal hereof will be made only if in the opinion of
the Bank there has been no material change of circumstances  and if there exists
no default under any Loan Documents executed by the Borrower.

     Borrowings  under the Line will be priced at the rates the Bank  quoted the
Borrower as:

     (1)  the Prime Rate (as hereinafter defined) presently 9.5%. or
     (2)  the "Money  Market" rates as we may quote you from time to time in the
          Bank's sole discretion.

     The  Borrower  agrees that the Bank may make loan  advances to the Borrower
upon  verbal  authority  of any  officer  executing  this  Note on behalf of the
Borrower or any other  officer of the Borrower who is  authorized  in writing to
borrow money from the Bank. As is typical for  facilities of this type, the Bank
retains  the  right  to  refuse  at any time any  borrowing  request  hereunder.
Borrowings at Money Market Rates may be requested for  maturities of 1 (one) day
up to a maximum of 90  (ninety)  days,  but shall not  exceed the Annual  Review
Date. All loans under the Line will be made by crediting the proceeds thereof to
the Borrower's  demand  deposit  account  maintained at the Bank,  which account
should be established prior to any advances under the Line. Borrowings under the
Money Market option must be in minimum increments of $500,000.  Borrowings under
the Money Market option are subject to the  availability  of funding sources and
the continued legality of the Bank offering such pricing option.

     If, at any time, (i) the interest rate on the Line is a fixed rate (such as
a Money Market Rate), and (ii) Bank in its sole discretion should determine that
current market conditions can accommodate a prepayment  request,  Borrower shall
have  the  right,  at any time and  from  time to time,  upon at least  ten (10)
Business  Days'  prior  written  notice to Bank,  to prepay  the loan  (which is
bearing interest at a fixed rate) in whole (but not in part), and Borrower shall
pay to Bank a yield  maintenance  fee in an  amount  computed  as  follows:  The
current rate for United States Treasury  securities (bills on a discounted basis
shall be converted  to a bond  equivalent)  with a maturity  date closest to the
maturity date of the term chosen pursuant to the Fixed Rate Election as to which
prepayment is made,  shall be subtracted  from the "Cost of Funds"  component of
the fixed rate in effect at the time of  prepayment.  If the result is zero or a
negative  number,  there shall be no yield  maintenance  fee. If the result is a
positive number, then the resulting percentage shall be multiplied by the amount
of the principal balance being prepaid. The resulting amount shall be divided by
360 and multiplied by the number of days  remaining in the term chosen  pursuant
to the Fixed Rate Election as to which the prepayment is made. Said amount shall
be reduced to present value calculated using the above-referenced  United States
Treasury  securities  rate and the number of days  remaining  in the term chosen
pursuant to the Fixed Rate  Election  as to which the  prepayment  is made.  The
resulting amount shall be the yield  maintenance fee due to Bank upon prepayment
of the fixed  rate  loan.  Each  reference  in this  paragraph  to  "Fixed  Rate
Election"  shall  mean  the  election  by  Borrower  pursuant  to the  foregoing
paragraph of this  Agreement.  "Cost of Funds" as used herein shall mean the per
annum rate of interest which Bank is required to pay, or is offering to pay, for
wholesale  liabilities of like tenor, adjusted for reserve requirements and such
other  requirements as may be imposed by federal,  state or local government and
regulatory agencies,  as determined by Bank. If by reason of an event of default
Bank elects to declare the Line to be  immediately  due and payable or if demand
is made by the Bank,  then any yield  maintenance  fee with  respect to the Line
shall become due and payable in the same manner as though Borrower had exercised
such right of prepayment.

     All Prime Rate and Money Market Rate  borrowings  shall be evidenced by the
Line of Credit  Promissory  Note in the form attached hereto and said promissory
note shall be executed by the  Borrower  prior to the Bank's  initiation  of the
Line. Each borrowing and the  corresponding  information will be recorded in our
computer data files. The Bank's corresponding records of debits and credits will
be additional  evidence of borrowing,  The Borrower  authorizes the Bank to keep
the official record of borrowing, under these facilities and the Borrower agrees
that, absent manifest error, this record shall be conclusive and binding.

     Interest  shall be  payable  monthly  in  arrears.  An unused  fee  payable
quarterly  at the rate of  one-quarter  of one  percent  (0.25%) per annum shall
apply to the daily average of unadvanced  amounts under the Line (based upon the
maximum  available amount of $16,000,000).  This fee shall be billed and payable
by the Borrower  quarterly in arrears.  Interest and fees are  calculated on the
basis of actual days elapsed over a three hundred sixty (360) day banking year.

     To induce the Bank to enter into this Agreement and to extend the Line, the
Borrower warrants, represents and covenants to the Bank that:

     1. The Borrower has full power and  authority to enter into this  Agreement
and to borrow  hereunder,  to execute and deliver this Agreement,  and any other
documents  the  purpose of which are to evidence or secure the Line and to incur
the obligations provided for herein and in the Loan Documents, all of which have
been duly authorized by all proper and necessary  corporate or other action. Any
consent or approval of stockholders, or of any agency or of any public authority
or of any other  party  required as a  condition  to the legal  validity of this
Agreement or the Loan Documents has been obtained.

     2. This Agreement and the Loan  Documents  constitute the valid and legally
binding obligations of the Borrower  enforceable in accordance with their terms;
provided, that the enforceability of any provisions in the Loan Documents, or of
any nights  granted to the Bank pursuant  thereto may be subject to and affected
by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws
affecting  the rights of creditors  generally  and that the right of the Bank to
specifically  enforce any provisions of the Loan Documents is subject to general
principles of equity.

     3.  There  is no  charter  provision  or  bylaw  of  the  Borrower,  and no
provision(s) of any existing mortgage,  indenture, contract or agreement binding
on the  Borrower  or  affecting  any of the  Borrower's  property,  which  would
conflict with, be in contravention  hereof, have a material adverse effect upon,
or in any way prevent the  execution,  delivery,  or performance of the terms of
this Agreement or the Loan Documents.

     4. No part of the proceeds  received by the Borrower  from the Line will be
used  directly or Indirectly  for the purpose of purchasing or carrying,  or for
payment in full or in part of  indebtedness  which was incurred for the purposes
of  purchasing  or  carrying  any  margin  stock,  as such  term is  defined  in
Regulation U of the Board of Governors of the Federal Reserve System.

     5. None of the  information  with  respect to the  Borrower  which has been
prepared  and  furnished  by the  Borrower  to the Bank in  connection  with the
transactions  contemplated  hereby is false or  misleading  with  respect to any
material  fact, or omits to state any material  fact  necessary in order to make
the statements, therein not misleading.

     6. The Borrower shall take all necessary  action to maintain the Borrower's
existence,  including  the filing of required  reports and, tax returns with the
Secretary  of  State  of the  State of New  Hampshire  and with the  appropriate
authorities in any other state where required.

     7. The Borrower shall promptly notify the Bank in writing of the occurrence
of any Event of Default under this Agreement (or any occurrence that would, with
the  passage  of time,  constitute  an Event of  Default)  or any other  loan or
financing arrangement.

     8. The Borrower  shall comply in all material  respects with all applicable
material laws, rules, regulations, and orders, provided, however , that Borrower
shall be  entitled to contest the same in good faith so long as such action does
not have an adverse  effect upon the Bank's  rights  hereunder  or the  security
furnished  therefor.  Without  limiting in any manner the scope or generality of
the foregoing,  the Borrower agrees to comply with all federal,  state and other
laws and regulations regarding the generation,  treatment,  storage, disposal or
transportation  of hazardous  waste or materials,  as defined  under  applicable
federal  and state  law;  and  agrees  to  defend,  indemnify  and hold the Bank
harmless from and against any and all liabilities, costs and expenses (including
reasonable  attorneys'  fees)  attributable  to or in any way connected with the
failure to comply with such laws and regulations.

     If the foregoing  satisfactorily sets forth the terms and conditions of the
Line,  please indicate your agreement by executing and returning this letter and
the attached Line of Credit  Promissory  Note, the terms and conditions of which
are incorporated herein by reference.

     We continue to enjoy  working with Unitil  Corporation  and look forward to
further expanding upon our long-standing and mutually beneficial relationship.

LINE OF CREDIT PROMISSORY NOTE $16,000,000 September 18, 2000 Manchester, New Hampshire FOR VALUE RECEIVED, UNITIL CORPORATION, a New Hampshire corporation with a principal place of business at 6 Liberty Lane West, Hampton, New Hampshire 03842 (the "Borrower") (the Borrower and all other persons primarily or secondarily liable hereunder or in respect hereto are sometimes referred to herein as the "Obligor"), hereby promises to pay, ON DEMAND, to the order of FLEET NATIONAL BANK, a national banking association organized and existing under the laws of the United States of America, with an office at 1155 Elm Street, Manchester, New Hampshire 03101 (the "Bank") (the Bank and any subsequent transferee of this Note, whether taking by negotiation or otherwise, are sometimes referred to herein as the "Holder") at such place of business or such other place as may be designated hereafter by the holder hereof, the principal sum of Sixteen Million Dollars ($16,000,000) (or so much thereof as may be advanced or readvanced by the Bank to the Borrower from time to time hereafter, such amounts defined as the "Debit Balance" below), together with interest on each such advance from the date thereof at a rate per annum equal to (a) the Prime Rate (as defined below) or (b) the Money Market Rate (as defined below), as elected by the Borrower. This Note is being executed and delivered in accordance with the terms of a certain Letter Agreement of even date between the Borrower and the Bank (the "Letter Agreement") and the documents defined therein as the "Loan Documents". Until such time as this Note becomes due and payable, interest shall be payable monthly in arrears commencing on that date thirty (30) days from the date hereof (or on such other date as may be agreed upon by the Borrower and the Bank to provide for a convenient payment date) and continuing on the corresponding day of each succeeding month thereafter. All payments required under this Note shall be made by the Borrower to the Bank at 1155 Elm Street, Manchester, New Hampshire or such other place as the Bank may from time to time specify in writing in lawful currency of the United States of America in immediately available funds, without counterclaim, or setoff and free and clear of, and without any deduction or withholding for any taxes or other payments. The maximum principal amount outstanding under this Note shall be limited to Sixteen Million Dollars ($16,000,000). Pursuant to the Letter Agreement, there shall be due and payable from the Borrower to the Bank, and the Borrower shall immediately pay to the Bank, without demand, any amount by which the Debit Balance exceeds Sixteen Million Dollars ($16,000,000). As used herein, "Prime Rate" shall mean the variable per annum rate of interest so designated from time to time by the Bank as its Prime Rate. The Prime Rate is a reference rate and does not necessarily represent the lowest or best rate being charged to any customer. Each time the Prime Rate changes, the interest rate hereunder shall change contemporaneously with such change in the Prime Rate without notice or demand of any kind. As used herein, "Money Market Rate" shall mean the overnight or term money market facilities interest rate per annum which is communicated to the Borrower by the Bank in respect of an advance evidenced hereby and which is accepted by the Borrower for such advance evidenced hereby or which is so communicated and is hereby deemed to be so accepted as a result of the Borrower's failure either to communicate its nonacceptance thereof or to repay such advance on the date when made. All amounts outstanding under the Line which the Borrower does not elect to be subject to the Money Market Rate shall bear interest at a variable annual rate equal to the Borrower's Prime Rate as provided hereinabove. Notwithstanding the foregoing provisions, the Borrower may not convert existing advances hereunder to Money Market Advances if at any time either an Event of Default or a payment Default exists under the Loan Documents. As used herein, "Money Market Advance" shall mean any amount outstanding under the Line as to which the Borrower has elected a Money Market Rate. Interest at the Prime Rate and the Money Market Rate shall be billed and payable monthly in arrears, calculated on the basis of actual days elapsed over a three hundred sixty (360) day banking year on the unpaid principal balance outstanding from time to time. The Borrower shall pay the Bank an unused fee equal to one-quarter of one percent (0.25%) per annum of the daily average of unadvanced amounts under the Line (based upon the maximum available amount of $16,000,000), determined and payable quarterly in arrears through and until the Annual Review Date. All payments shall be made in lawful currency of the United States of America in immediately available funds. The Bank is authorized to charge the Borrower's deposit account(s) maintained with the Bank to effect any payment on this Note. The Following Business Day Convention shall be used to adjust any relevant date if that date would otherwise fall on a day that is not a Business Day. For the purposes herein, the term Following Business Day Convention shall mean that an adjustment will be made if any relevant date would otherwise fall on a day that is not a Business Day so that the date will be the first following day that is a Business Day. "Business Day" means, in respect of any date that is specified in this Loan Agreement or any Loan Document to be subject to adjustment in accordance with the Following Business Day Convention, a day on which commercial banks settle payments in (i) London, if the payment obligation is calculated by reference to LIBOR, or (ii) New York, if the payment obligation is calculated by reference to Prime Rate, CD Rate, or COF Rate. All payments hereunder or under any Loan Documents hereunder shall be adjusted in accordance with the Following Business Day Convention. All payments under the Loan Documents shall be applied first to the payment of all fees, expenses and other amounts due to the Bank (excluding principal and interest), then to accrued interest, and the balance on account of outstanding principal; provided, however, that after demand payments will be applied to the obligations of Borrower to Bank as Bank determines in its sole discretion. Notwithstanding anything herein to the contrary, in the event that the interest rate hereunder, as aforesaid, violates any applicable usury or similar statute, the interest rate shall then automatically be deemed to be the highest rate of interest then permitted. The Borrower agrees that the Bank may make loan advances to the Borrower upon verbal authority (which, if the Bank so requires, shall be followed by written confirmation) of any officer executing this Note on behalf of the Borrower or any other officer of the Borrower who is authorized in writing to borrow money from the Bank and may deliver such advances by direct deposit to any deposit account of the Borrower with the Bank or otherwise as may be authorized in the Letter Agreement. All such advances shall represent binding obligations of the Borrower. The Borrower's "Debit Balance" shall mean the debit balance in an account on the books of the Bank, maintained in the form of a ledger card, computer records or otherwise in accordance with the Bank's customary practice and appropriate accounting procedures wherein there shall be recorded the principal amount of all advances made by the Bank to the Borrower, all principal payments made by the Borrower to the Bank hereunder, and all other appropriate debits and credits (the "Loan Account"). The Bank shall render to the Borrower a statement of account with respect to the Loan Account on a monthly basis. Such statement shall indicate the Borrower's then current Debit Balance and any interest amounts due and payable from the Borrower to Bank. Such statement may be based on estimates of the principal amount outstanding and the interest rate for the applicable payment period. Any required adjustments between such estimates and actual amounts shall be reflected in subsequent statements. The Borrower acknowledges that this Note is to evidence the Borrower's obligation to pay the Debit Balance, plus interest, as determined from time to time and that it shall continue to do so despite the occurrence of intervals when no Debit Balance exists because the Borrower has paid the previously existing Debit Balance in full. This Note is a DEMAND OBLIGATION. At the option of the Bank, this Note shall become immediately due and payable in full, without further demand or notice, on the earlier of (i) demand by the Bank, or (ii) the occurrence of an Event of Default (as defined below). If the entire amount of any required principal and/or interest is not paid in full within ten (10) days after the same is due, Borrower shall pay to Bank a late fee equal to five percent (5%) of the required payment. Upon default (whether or not Bank has accelerated payment of this Note), upon demand or after maturity or after judgment has been rendered on this Note, the unpaid principal of all advances shall, at the option of Bank, bear interest at a rate which is two percentage (2%) points per annum greater than that which would otherwise be applicable. The Borrower agrees to pay on demand all reasonable out-of-pocket costs of collection hereof, including reasonable attorneys' fees, whether or not any foreclosure or other action is instituted by the Holder in its discretion. The Borrower hereby acknowledges that its liability to the Bank under the Line is a DEMAND OBLIGATION and that nothing herein shall alter or otherwise affect the ability of the Bank to demand payment in full of the same. Subject to the foregoing, if any of the following events of default shall occur ("Event of Default"): (a) default in the payment or performance of any of the Obligations or of any obligations of any Obligor to others for borrowed money or in respect of any extension of credit or accommodation; (b) failure of any representation or warranty, statement or information in any documents or financial statements delivered to the Holder for the purpose of inducing it to make or maintain any loan under this Note to be true and correct; (c) failure of the undersigned to file any tax return, or to pay or remit any tax, when due, unless the undersigned contests the particular tax in good faith, and also maintains adequate reserves to pay such tax, if unsuccessful in its action to contest; (d) failure to furnish the Holder promptly on request with financial information about, or to permit inspection by the Holder of books, records and properties to any Obligor; (e) any Obligor generally not paying its debts as they become due; (f) death, dissolution, termination of existence, insolvency, business failure, appointment of a receiver or other custodian of any part of the property of, assignment for the benefit of creditors by, or the commencement of any proceedings (except for an involuntary bankruptcy petition against any Obligor to which such Obligor files a proper answer thereto pursuant to Section 303(d) of the Bankruptcy Code (11 USC 303(d)) within ten (10) days of receipt of notice of said proceeding, which answer shall include a request that petitioning creditors post adequate bond under Section 303(e) (11 USC 303(e)) under any bankruptcy or insolvency laws by or against, any Obligor; (g) a material adverse change in the condition or affairs (financial or otherwise) of any Obligor which in the opinion of the Holder will impair its security or increase its risk including but not limited to any reduction of any Obligor's tangible net worth by more than 10% from its level at the previous fiscal year end or the occurrence of operating losses for any consecutive twelve month period; then the Holder shall give written notice of such default and if such default is not cured within five business days of delivery of such notice then immediately and automatically with respect to any Defaults set forth in clauses (e) and (f) above, and thereupon or at any time thereafter with respect to each other Default (such Default not having been previously cured), at the option of the Holder, all Obligations of the Obligor shall become immediately due and payable without demand, and, if there is any collateral for the Obligations, the Holder shall then have in any jurisdiction where enforcement hereof is sought, in addition to all other rights and remedies the rights and remedies of a secured party under the Uniform Commercial Code as in effect in the State of New Hampshire. As used herein, "Obligation" means any obligation hereunder or otherwise of any Obligor to the holder whether direct or indirect, absolute or contingent, due or to become due, now existing or hereafter arising. Borrower hereby grants to the Bank, a continuing lien, security interest and right of setoff as security for all liabilities and obligations to the Bank, whether now existing or hereafter arising, upon and against all deposits, credits, collateral and property, now or hereafter in the possession, custody, safekeeping or control of the Bank or any entity under the control of FleetBoston Financial Corporation, or in transit to any of them. At any time, without demand or notice (any such notice being expressly waived by Borrower), the Bank may set off the same or any part thereof and apply the same to any liability or obligation of the Borrower even though unmatured and regardless of the adequacy of any other collateral securing the Line. ANY AND ALL RIGHTS TO REQUIRE THE BANK TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH SECURES THE LOANS, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF THE BORROWER, ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED. BORROWER AND BANK (BY ACCEPTANCE OF THIS NOTE) MUTUALLY HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE THE RIGHT TO A TRIAL BY JURY IN RESPECT OF ANY CLAIM BASED HEREIN, ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS NOTE OR ANY OTHER LOAN DOCUMENTS CONTEMPLATED TO BE EXECUTED IN CONNECTION HEREWITH OR ANY COURSE OF CONDUCT, COURSE OF DEALINGS, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY PARTY, INCLUDING, WITHOUT LIMITATION, ANY COURSE OF CONDUCT, COURSE OF DEALINGS, STATEMENTS OR ACTIONS OF BANK RELATING TO THE ADMINISTRATION OF THE LOANS OR ENFORCEMENT OF THE LOAN DOCUMENTS, AND AGREE THAT NEITHER PARTY WILL SEEK TO CONSOLIDATE ANY SUCH ACTION WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT BE OR HAS NOT BEEN WAIVED. EXCEPT AS PROHIBITED BY LAW, BORROWER HEREBY WAIVES ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY LITIGATION ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES OR ANY DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES. BORROWER CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF BANK HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT BANK WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER. THIS WAIVER CONSTITUTES A MATERIAL INDUCEMENT FOR BANK TO ACCEPT THIS NOTE AND MAKE THE LOAN. No delay or omission on the part of the Holder in exercising any right, privilege or remedy shall impair such right, privilege or remedy or be construed as a waiver thereof or of any other right, privilege or remedy. No waiver of any right, privilege or remedy or any amendment to this Note shall be effective unless made in writing and signed by the Holder. Under no circumstances shall an effective waiver of any right, privilege or remedy on any one occasion constitute or be construed as a bar to the exercise of or a waiver of such right, privilege or remedy on any future occasion. The acceptance by the Holder hereof of and payment after any default hereunder shall not operate to extend the time of payment of any amount then remaining unpaid hereunder or constitute a waiver of any rights of the Holder hereof under this Note. This Note and the Loan Documents together are intended by the parties as the final, complete and exclusive statement of the transactions evidenced by this Agreement and Loan Document. All prior or contemporaneous promises, agreements and understandings, whether oral or written, are deemed to be superceded by the Loan Documents, and no party is relying on any promise, agreement or understanding not set forth in the Loan Documents. The Loan Documents may not be amended or modified except by a written instrument describing such amendment or modification executed by Borrower and Bank. All rights and remedies of the Holder, whether granted herein or otherwise, shall be cumulative and may be exercised singularly or concurrently, and the Holder shall have, in addition to all other rights and remedies, the rights and remedies of a secured party under the Uniform Commercial Code of New Hampshire. The Borrower waives, to the fullest extent permitted by law, presentment, notice, protest and all other demands and notices and assent (1) to any extension of the time of payment or any other indulgence, (2) to any substitution, exchange or release of collateral, and (3) to the release of any other person primarily or secondarily liable for the obligations evidenced hereby. Bank may at any time pledge or assign all or any portion of its rights under the Loan Documents including any portion of the promissory note to any twelve (12) Federal Reserve Banks organized under Section 4 of the Federal Reserve Act, 12 U.S.C. Section 341. No such pledge or assignment or enforcement thereof shall release Bank from its obligations under any of the Loan Documents. Bank shall have the unrestricted right at any time or from time to time, and without Borrower's consent, to assign all or any portion of its rights and obligations hereunder to one or more banks or other financial institutions (each, an "Assignee"), and Borrower agrees that it shall execute, or cause to be executed, such documents, including without limitation, amendments to this Agreement and to any other documents, instruments and agreements executed in connection herewith as Bank shall deem necessary to effect the foregoing. In addition, at the request of Bank and any such Assignee, Borrower shall issue one or more new promissory notes, as applicable, to any such Assignee and, if Bank has retained any of its rights and obligations hereunder following such assignment, to Bank, which new promissory notes shall be issued in replacement of, but not in discharge of, the liability evidenced by the promissory note held by Bank prior to such assignment and shall reflect the amount of the respective commitments and loans held by such Assignee and bank after giving effect to such assignment. Upon the execution and delivery of appropriate assignment documentation, amendments and any other documentation required by Bank in connection with such assignment, and the payment by Assignee of the purchase price agreed to by Bank, and such Assignee, such Assignee shall be a party to this Agreement and shall have all of the rights and obligations of Bank hereunder (and under any and all other guaranties, documents, instruments and agreements executed in connection herewith) to the extent that such rights and obligations have been assigned by Bank pursuant to the assignment documentation between Bank and such Assignee, and Bank shall be released from its obligations hereunder and thereunder to a corresponding extent. Borrower may furnish any information concerning Borrower in its possession from time to time to prospective Assignees, provided that Bank shall require any such prospective Assignees to agree in writing to maintain the confidentiality of such information. Bank shall have the unrestricted right at any time and from time to time, and without consent of or notice to Borrower, to grant to one or more banks or other financial institutions (each a "Participant") participating interests in any or all of the loans held by Bank hereunder. In the event of any such grant by Bank of a participating interest to a participant, whether or not upon notice to Borrower, Bank shall remain responsible for the performance of its obligations hereunder and Borrower shall continue to deal solely and directly with Bank in connection with Bank's rights and obligations hereunder. Bank may furnish any information concerning the Borrower in its possession from time to time to prospective Participants, provided that Bank shall require any such prospective Participant to agree in writing to maintain the confidentiality of such information. The Borrower shall pay on demand all expenses of the Bank in connection with the preparation, administration, default, collection, waiver or amendment of loan terms, or in connection with Bank's exercise, preservation or enforcement of any of its rights, remedies or options hereunder, including, without limitation, fees of outside legal counsel or the allocated costs of in-house legal counsel, accounting, consulting, brokerage or other similar professional fees or expenses and any fees or expenses associated with travel or other costs relating to any appraisals or examinations conducted in connection with the loan or any collateral therefor, and the amount of all such expenses shall, until paid, bear interest at the rate applicable to principal hereunder (including any default rate) and be an obligation secured by any collateral. Upon receipt of an affidavit of an officer of Bank as to the loss, theft, destruction, or mutilation of this Promissory Note or any other security documents which are not of public record, and in the case of any such loss, theft, destruction or mutilation, upon cancellation of such note or other security documents, Borrower will issue, in lieu thereof, a replacement note or other security document in the same principal amount thereof and otherwise of like tenor. All agreements between Borrower and Bank are hereby expressly limited so that in no contingency or event whatsoever, whether by reason of acceleration of maturity of the indebtedness evidenced hereby or otherwise, shall the amount paid or agreed to be paid to Bank for the use or the forbearance of indebtedness evidenced hereby exceed the maximum permissible under law. As used herein, the term "applicable law" shall mean the law in effect as of the date hereof; provided, however, that in the event there is a change in the law which results in a higher permissible rate of interest, then this document shall be governed by such new law as of its effective date. In this regard, it is expressly agreed that it is the intent of Borrower and Bank in the execution, delivery and acceptance of this document to contract in strict compliance with the laws of the State of New Hampshire from time to time in effect. If, under or from any circumstances whatsoever, fulfillment of any provision hereof or of any of the loan documents at the time of performance of such provision shall be due, shall involve transcending the limit of such validity prescribed by applicable law, then the obligation to be fulfilled shall automatically be reduced to limits of such validity, and if under or from circumstances whatsoever Bank should ever receive as interest in an amount which would exceed the highest lawful rate, such amount would be excessive interest shall be applied to the reduction of the principal balance evidenced hereby and not to the payment of interest. This provision shall control every other provision of all agreements between Borrower and Bank. This Note and the provisions hereof shall be binding upon the Borrower and the Borrower's heirs, administrators, executors, successors, legal representatives and assigns and shall inure to the benefit of the Holder, the Holder's heirs, administrators, executors, successors, legal representatives and assigns.

September 25, 2000


Mr. Mark Collin, Vice President
Unitil Corp.
6 Liberty Lane West
Hampton, NH 03842-1720


Dear Mark:

We are pleased to advise you that  Sovereign  Bank (the  "Bank") has approved an
unsecured line of credit in the maximum principal amount of Four Million Dollars
($4,000,000) (the "Line") for Unitil Corporation (the "Borrower") subject to the
Bank's periodic review.  Unless renewed,  this line will expire on June 30, 2001
(the "Annual Review Date").

This  letter,  together  with the related  Line of Credit  Promissory  Note (the
"Note") of near or even date (collectively,  the "Loan Documents"),  shall serve
as our agreement concerning the terms and conditions of your borrowing under the
Line.

1) Principal Advances. The Borrower may request principal advances from the Bank
from time to time, provided that any given principal advance shall not cause the
Borrower's liability to exceed  $4,000,000.00.  Such request shall be granted on
the day such request is received,  provided  that a) such request is received by
2:00 p.m. on a Bank business day, and b) the Bank is reasonably  satisfied  that
the conditions set forth in this Agreement have been  satisfied.  The Bank shall
credit the amount of the request to the  designated  account of the  Borrower in
immediately payable funds.

Advances  hereunder  will be made only if in the  opinion  of the Bank there has
been no negative material change of circumstances and if there exists no default
under any loan  documentation  executed  by you.  The Bank  retains the right to
refuse at any time any borrowing request hereunder.

All loans will be made by crediting the proceeds  thereof to your demand deposit
account maintained at the Bank, which account should be established prior to any
advances under the line.

2)  Interest.  Borrowings under the Line accrue interest at the following rates:

(1) Our "Prime Rate" as announced from time to time; or

(2) a fixed rate based on an index  plus a margin to be  determined  by the Bank
from time to time.  Such indexes shaft be the "LIBOR rate",  as set forth in the
Note, or our "Cost of Funds Rate", as set forth in the Note.

Unless the LIBOR or Cost of Funds rate is specifically  elected,  the Prime Rate
shall apply.

Each  rate will be as  determined  by the Bank by 10:00  a.m.  on the day of the
requested  borrowing.  Each  borrowing  under this line by you must  specify the
amount of the loan requested, the rate requested and the maturity requested.

Borrowings at LIBOR rates may be requested for  maturities of one, two, or three
month  periods,  but no  such  period  shall  exceed  the  Annual  Review  Date.
Borrowings at the Cost of Funds rate may be requested for  maturities of 1 (one)
or 7 (seven) day  periods,  but no such periods  shall exceed the Annual  Review
Date.

Borrowings  under the LIBOR or Cost of Funds  rate  options  must be in  minimum
increments of $1,000,000 or greater  multiples of $100,000,  and your ability to
prepay such  borrowings is subject to a requirement  that you  compensate us for
any funding losses and other costs (including lost profits) incurred as a result
of such prepayment, as set forth in the Note.

Borrowings  at LIBOR or Cost of Funds rates are subject to the  availability  of
funding sources and the continued legality of our offering such pricing option.

3) Borrowing Rate Option.  The Borrower may, from time to time,  elect to adjust
the interest rate  applicable to the Borrower's  outstanding  principal  balance
from the Prime Rate to either of the rates  designated at the Bank's  discretion
as of such date as its LIBOR or Cost of Funds rates. The LIBOR and Cost of Funds
rates shall be the sum of such respective  index (as defined in the Note) plus a
margin to be chosen by the Bank. The LIBOR and Cost of Funds rates for any given
day on which the Bank is open for regular  banking  business  shall be available
from the Bank by 10:00 a.m. on each such day.

     Should  the  Borrower  elect  to  have  the  Daily  Borrowing  Rate  Option
available,  which shall include  daily fax  notification  of the  then-available
rate, a monthly service fee of $300 shall be charged to the Borrower by the Bank
for any month during which such availability is elected.

4) Bank Records  Conclusive.  All  borrowings  shall be evidenced by the Line of
Credit  Promissory  Note in the form attached and requiring  execution  prior to
initiation of the Line. Each borrowing and the corresponding information will be
recorded in our computer  data files.  Our  corresponding  records of debits and
credits will be additional evidence of borrowings.  You authorize us to keep the
official record or borrowing,  under these facilities and you agree that, absent
manifest error, this record shall be conclusive and binding.

5) Default Rate.  Upon demand or Default or after maturity or after judgment has
been rendered on this Loan  Agreement,  or in the Event of Default as defined in
the Note,  Borrower's right to select pricing options shall cease and the unpaid
principal of all advances  shall,  at the option of the Bank, bear interest at a
rate which is four (4)  percentage  points per annum greater than the Prime Rate
("Default rate").

6) Automatic Payments.  Borrower hereby authorizes Bank to automatically  deduct
from  Borrower's  account  designated  for such  purpose  the amount of any loan
payment ("Automatic Payments").  If the funds in the account are insufficient to
cover any payment,  Bank shall not be  obligated  to advance  funds to cover the
payment.  At any  time and for any  reason,  Borrower  or Bank  may  voluntarily
terminate Automatic Payments.

7) Conditions of Lending.

     Initial Loan.  The  agreement of the Bank to provide the Line  hereunder is
subject to the following conditions precedent:

     (A) The Bank shall have received a certified  copy of all corporate  action

the Loan  Documents and the borrowing by it hereunder,  and such other papers as
the Bank shall reasonably require on the form or forms provided by the Bank.

     (B) Should the Bank so require,  the Bank shall have received an opinion of
counsel to the Borrower,  in form and substance  satisfactory to the Bank and to
McLane, Graf, Raulerson & Middleton, P.A., counsel to the Bank, as to the matter
referred to in  paragraphs 9 (A),  (B),  (C) and (F) hereof,  and further to the
effect that this Agreement has been duly authorized, executed, and delivered and
is a legal, valid, binding, and enforceable agreement of the Borrower.

     (C) Any other  conditions  precedent  required under the Bank's  Commitment

individually  or  cumulatively,  may result in a material  adverse change in the
financial condition of the Borrower.

     D. Compliance with Laws and Regulations. The Borrower shall comply with all
applicable  laws,  ordinances,   regulations,  and  other  requirements  of  any
jurisdiction  or agency  having or claiming  authority  over the Borrower or any

Agreement.

     B. Corporate and Regulatory  Authority.  The making and  performance by the
Borrower  of the Loan  Documents  have been  duly  authorized  by all  necessary
corporate and regulatory  action and will not violate any provision of law or of
its Articles of Incorporation by bylaws.

     C.  Financial  Condition.   The  reports,   including  balance  sheets  and
statements of income and retained earnings of the Borrower and its subsidiaries,
heretofore  and  henceforth  furnished to the Bank, are complete and correct and
fairly represent the financial condition of the Borrower and its subsidiaries as
at the dates of said financial  statements  and the results of their  operations
for the  periods  ending on said  dates.  Neither  the  Borrower  nor any of its
subsidiaries  has any material  contingent  obligations,  liabilities for taxes,
long-term leases, or unusual forward or long-term  commitments not disclosed by,
or reserved  against in, said balance  sheets or the notes  thereto;  and at the
present time there are no material  unrealized  or  anticipated  losses from any
unfavorable  commitments  of the  Borrower  or any  subsidiary.  Said  financial
statements  were prepared in accordance with generally  accepted  principles and
practices of accounting consistently maintained throughout the periods involved.
Since the date of the  latest  of such  statements  there  has been no  material
adverse change in the financial  condition of the Borrower and its  subsidiaries
from that set in said balance sheets as at that date.

     D. Taxes.  Borrower has filed all federal,  state and local tax returns and
other reports it is required to file,  and has paid or made  adequate  provision
for payment of all such taxes, assessments and other governmental charges.

     E.  Litigation.  There  are no  suits  or  proceedings  pending,  or to the
knowledge of the Borrower threatened against or affecting the Borrower or any of
its  subsidiaries,  and there are no proceedings  by or before any  governmental
commission,  board,  bureau, or other  administrative  agency pending or, to the
knowledge  of the  Borrower,  threatened,  against  the  Borrower  or any of its
subsidiaries  which,  if  adversely  determined,  would have a material  adverse
effect  on  the  financial   condition  or  business  of  the  Borrower  or  its
subsidiaries.

     F. Not  Misleading.  No  representation,  warranty or statement by Borrower
contained  herein or in any  certificates  or other  document  finished or to be
furnished by Borrower  pursuant hereto contains or at the time of delivery shall
contain any untrue  statement of material  fact, or omits,  or shall omit at the
time of delivery to state a material fact necessary to make it not misleading.

10) Federal Reserve. Bank may at any time pledge,  endorse,  assign, or transfer
all or any portion of its rights under the Loan Documents  including any portion
of the Promissory Note to any of the twelve (12) Federal Reserve Banks organized
under  Section 4 of the Federal  Reserve  Act.  12.U.S.C.  Section  341. No such
pledge or enforcement  thereof shall release Bank from its obligations under any
of the Loan Documents.

11) Third Party Purchaser. Bank shall have the unrestricted right at any time or
from time to time, and without Borrower's consent, to sell, assign,  endorse, or
transfer  all or any portion of its rights and  obligations  hereunder to one or
more banks or other entities (each, an "Assignee") and,  Borrower agrees that it
shall  execute,  or  cause  to be  executed  such  documents  including  without
limitation, amendments to this Agreement and to any other documents, instruments
and agreements  executed in connection  herewith as Bank shall deem necessary to
effect the foregoing. In addition, at the request of Bank and any such Assignee,
Borrower shall issue on or more new promissory notes, as applicable, to any such
Assignee and, if Bank has retained any of its rights and  obligations  hereunder
following such  assignment,  to Bank, which new promissory notes shall be issued
in replacement of, but not in discharge of, the liability  evidenced by the note
held by Bank  prior to such  assignment  and  shall  reflect  the  amount of the
respective  commitments  and loans held by such  Assignee  and Bank after giving
effect to such  assignment.  Upon the  execution  and  delivery  of  appropriate
assignment  documentation,  amendments and any other  documentation  required by
Bank in  connection  with such  assignment,  and the  payment by Assignee of the
purchase  price agreed to by Bank and such  Assignee,  such Assignee  shall be a
party to this Agreement and shall have all of the rights and obligations of Bank
hereunder (and under any and all other  guaranties,  documents,  instruments and
agreements  executed in connection  herewith) to the extent that such rights and
obligations have been assigned by Bank pursuant to the assignment  documentation
between  Bank and  Assignee,  and Bank shall be  released  from its  obligations
hereunder and thereunder to a corresponding extent.

12)  Participation.  Bank shall have the unrestricted right at any time and from
time to time,  and  without the consent of or notice to Borrower to grant to one
or more  institutions  or other  persons  (each a  "Participant")  participating
interests in Bank's obligations to lend hereunder and/or any or all of the loans
held  by  Bank  hereunder.  In  the  event  of  any  such  grant  by  Bank  of a
participating interest to a Participant; whether or not upon notice to Borrower,
Bank shall remain  responsible for the performance of its obligations  hereunder
and Borrower  shall continue to deal solely and directly with Bank in connection
with Bank's rights and obligations hereunder.

Bank may furnish any information concerning Borrower in its possession from time
to time to any prospective assignees and Participants,  provided that Bank shall
require  any  such   prospective   assignee  or   Participant  to  maintain  the
confidentiality of such information.

13) Right to Set Off.  Borrower hereby grants to Bank a lien,  security interest
and a right of setoff as security for all  liabilities  and obligations to Bank,
whether  now  existing or  hereafter  arising,  upon and  against all  deposits,
credits,  collateral and property, now or hereafter in the possession,  custody,
safekeeping  or control of Bank or any entity  under the control of Bank,  or in
transit to any of them. At any time, without demand or notice,  Bank may set off
the same or any part thereof and apply the same to any  liability or  obligation
of Borrower even though  unmatured  and  regardless of the adequacy of any other
collateral securing the loan. ANY AND ALL RIGHTS TO REQUIRE BANK TO EXERCISE ITS
RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER  COLLATERAL WHICH SECURES THE LOAN,
PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH  DEPOSITS,  CREDITS
OR OTHER  PROPERTY  OF THE  BORROWER,  ARE  HEREBY  KNOWINGLY,  VOLUNTARILY  AND
IRREVOCABLY  WAIVED. Bank shall not be required to marshal any present or future
security  for,  or  guarantees  of,  the  obligations  or to  resort to any such
security or guarantee in any particular  order and the Borrower  waives,  to the
fullest  extent that it lawfully  can,  (a) any right they might have to require
the Bank to pursue any particular remedy before proceeding  against them and (b)
any right to the benefit of, or to direct the application of the proceeds of any
collateral until the obligations are paid in full.

14) Replacement Documents. Upon receipt of an affidavit of an officer of Bank as
to the loss, theft,  destruction or mutilation of the Note or any other security
document(s)  which  is  not of  public  record  and,  in the  case  of any  such
destruction or mutilation, upon surrender and cancellation of such Note or other
document(s),  the Borrower will issue,  in lieu thereof,  a replacement  Note or
other  document(s)  in the same  principal  amount thereof and otherwise of like
tenor.

15)  Waiver  of  Jury  Trial.  Borrower  and  Bank  mutually  hereby  knowingly,
voluntarily and  intentionally  waive the right to a trial by jury in respect of
any  claim  based  hereon,  arising  out of,  under or in  connection  with this
Agreement  or any other  documents  contemplated  to be executed  in  connection
herewith or any course of conduct, course of dealing, statements (whether verbal
or  written)  or  actions  of any  party.  This  waiver  constitutes  a material
inducement for Bank to accept this Agreement and make the Loan.

16) Fees. The Borrower shall assume  responsibility  for all legal and other out
of pocket  expenses  incurred in the  documentation  of this  commitment  and in
addition shall pay the Bank an annual commitment fee of $1,500.

17) Waiver. The failure of Bank at any time or times hereafter to require strict
performance  by  Borrower  of any  of  the  provisions,  warranties,  terms  and
conditions contained in the Loan Documents or in any other agreement,  guaranty,
note,  instrument or document now or at any time or times hereafter  executed by
Borrower and delivered to Bank shall not waive,  affect or diminish any right of
Bank at any time or times thereafter to demand strict performance  thereof;  and
no rights of Bank  hereunder  shall be deemed to have been  waived by any act or
knowledge  of Bank,  its agents,  officers or  employees,  unless such waiver is
contained in an instrument in writing  signed by an officer of Bank and directed
to Borrower specifying such waiver. No waiver by Bank of any of its rights shall
operate  as a waiver of any other of its rights or any of its rights on a future
occasion.

18) Capital Adequacy.  If after the day hereof, the Bank determines that (i) the
adoption of any applicable law, rule or regulation of regarding requirements for
banks or bank holding companies in subsidiaries  thereof; (ii) any change in the
interpretation  or  administration  of any such law,  rule or  regulation by any
governmental  authority,  central bank, or  comparable  agency  charged with the
interpretation  or  administration  thereof;  or (iii) compliance by Bank or its
holding  company with any request or directive  of any  governmental  authority,
central bank, or comparable  agency regarding  capital adequacy (or not having a
force of law),  has the effect of reducing the return on the Bank's capital to a
level below that which Bank could have achieved  (taking into account the Bank's
and its  holding  company's  policies  with  respect  to  capital  adequacy  and
immediately before such adoption,  change or compliance and assuming that Bank's
capital was fully utilized prior to such adoption, change or compliance) but for
such adoption, change or compliance as a consequence of the Bank's commitment to
make advances  pursuant  hereto by any amount deemed by the Bank to be material;
then Bank shall promptly,  after Bank's  determination of such occurrence,  give
notice to the Borrower,  and the Borrower shall pay to the Bank as an additional
fee from time to time on demand,  such amount as Bank certifies to be the lowest
amount that will be required to compensate  the Bank for any such  reduction.  A
certificate  from the Bank claiming  entitlement to  compensation as provided in
this  Section  shall be  conclusive  in the  absence  of  manifest  error.  Said
certificate  will be delivered to the Borrower and shall set forth the nature of
the  occurrence  giving rise to any such need for  compensation,  the additional
amount or amounts to be paid to the Bank,  and the method by which such  amounts
were determined. In determining any such amount, the Bank may use any reasonable
averaging or attribution  method.  Any  adjustment  will be no greater than that
calculated to be  proportionate  to the Borrower's  loan in  relationship to the
rest of the Bank's loan portfolio of similar risk.

19) Notice.  Any demand or notice  required or permitted  to be given  hereunder
shall be deemed  effective when delivered in the United States mail, and sent by
certified mail, return receipt requested,  postage prepaid, addressed to Bank at
Bank's address or to Borrower at Borrower's address,  as applicable,  or to such
other  address as may be provided by the party to be notified,  on ten (10) days
prior written notice to the other party.

20) Entire  Understanding.  The Loan Documents contain the entire  understanding
between the parties hereto with respect to the transactions  contemplated herein
and such  understanding  shall not be modified except in writing signed by or on
behalf of the parties hereto.

21) Severability.  Wherever possible, each provision of the Loan Documents shall
be interpreted in such manner as to be effective and valid under applicable law;
should any  portion of any of the Loan  Documents  be  declared  invalid for any
reason in any  jurisdiction,  such  declaration  shall  have no effect  upon the
remaining portions of the Loan Documents;  furthermore, the entirety of the Loan
Documents  shall  continue in full force and effect in all other  jurisdictions,
Said remaining  portions of the Loan Documents  shall continue in full force and
effect in the subject  jurisdiction  as if this Agreement had been executed with
the invalid portions thereof deleted.

22)  Non-Assignability.  The provisions of the Loan  Documents  shall be binding
upon and shall inure to the benefit of the heirs, administrators, successors and
assigns of Bank and Borrower;  provided, however, Borrower may not assign any of
its  rights or  delegate  any of its  obligations  hereunder  without  the prior
written consent of the Bank.

23)  Jurisdiction.  The Loan  Documents  are and shall be deemed to be contracts
entered  into and made  pursuant to the laws of the State of New  Hampshire  and
shall in all respects be governed, construed, applied and enforced in accordance
with the laws of said  state;  in the  event  that the Bank  brings  any  action
hereunder  in any court of record of New  Hampshire  or the Federal  Government,
Borrower  consents to and confers  personal  jurisdiction  over Borrower by such
court or courts and agrees that service of process may be made upon  Borrower by
mailing a copy of the  summons to  Borrower at  Borrower's  address;  and in any
action hereunder Borrower waives the right to demand a trial by jury.

24) Costs of Counsel.  If, prior hereto  and/or at any time or times  hereafter,
Bank shall employ counsel in connection  with the execution and  consummation of
the  transactions  contemplated  by  any or all  of  the  Loan  Documents  or to
commence,  defend or intervene,  file a petition,  complaint,  answer, motion or
other  pleadings,  or to take any other action on or with respect to any suit or
proceeding (bankruptcy or otherwise) relating to any Loan Documents or any other
agreement, guaranty, note, instrument or document heretofore, now or at any time
or times hereafter executed by Borrower and delivered to Bank, or to enforce any
rights of Bank hereunder, whether before or after the occurrence of any Event of
Default,  or to collect any of the Obligations,  then in any of such events, all
of the reasonable attorneys' fees arising from such services,  and any expenses,
costs and charges relating  thereto,  shall be part of the outstanding  balance,
payable on demand.

25)  Counterparts.  Any of the Loan  Documents  may be executed in any number of
counterparts,  each of which shall be deemed to be an original, but all of which
together shall constitute but one and the same instrument.

26)  Succession.  Each  reference  herein to Bank shall be deemed to include its
successors  and  assigns,  and  each  reference  to  Borrower  and any  pronouns
referring thereto as used herein shall be construed in the masculine,  feminine,
neuter,  singular or plural, as the context may require,  and shall be deemed to
include the legal  representatives,  successors and assigns of Borrower,  all of
which  shall be bound by the  provisions  hereof.  The term  "Borrower"  as used
herein  shall,  if this  Agreement  is signed by more than one  Borrower,  mean,
unless  this  Agreement  otherwise  provides  or unless  the  context  otherwise
requires,  the  "Borrower  and each of them" and each and every  representation,
promise,  agreement and undertaking shall be joint and several,  except that the
granting of the  security  interest,  right of set-off and lien shall be by each
Borrower in its  several  respective  property.  In the event that there is more
than one Borrower, any loan which is secured by this Agreement,  shall be deemed
to be made at the request of and for the benefit of each Borrower.

27) Headings.  The section headings herein are included for convenience only and
shall not be deemed to be a part of this Agreement.

28) Costs.  The Borrower will pay, whether or not any Advance is made hereunder,
all  out-of-pocket  expenses  of the Bank in  connection  with the  preparation,
execution, and delivery hereof and of any Advance, including reasonable fees and
disbursements of counsel to the Bank.

If the foregoing satisfactorily sets forth the terms and conditions of the Line,
please  indicate your  agreement by executing and returning  this letter and the
attached Line of Credit Promissory Note.

We  continue to enjoy  working  with Unitil  Corp.  and look  forward to further
expanding upon our long-standing and mutually beneficial relationship.

All payments shall be made in lawful money of the United States of America, in immediately available funds. This Note is being executed and delivered in accordance with the terms of a certain Letter Agreement of even date between the Borrower and the Bank (the "Letter Agreement") and the documents defined therein as the "Loan Documents". Until such time as this Note becomes due and payable, the Borrower shall pay to the Bank the sum of the Interest Period Interest Charges (as set forth below) monthly in arrears commencing on or by the like-numbered date of the next month from the date hereof (or on such other date as may be agreed upon by the Borrower and the Bank to provide for a convenient payment date) and continuing on or by the corresponding day of each succeeding month thereafter. If any due date falls on a non-Business Day, the payment shall be due on the next Business Day. A "Business Day" shall mean, with respect to any date that is specified in this Note to be subject to adjustment in accordance with applicable Business Day convention, (i) a day on which commercial banks settle payments in New York or London if the payment obligation is calculated by reference to any LIBOR Rate, or (ii) in any other case, any day on which the Bank is open for business. The "Modified Following Business Day Convention" shall mean the convention for adjusting any relevant date if it would otherwise fall on a day that is not a Business Day. The following terms, when used in conjunction with the term "Modified Following Business Day Convention" and a date, shall mean that an adjustment will be made if that date would otherwise fall on a day that is not a Business Day so that the date will be the first following day that is a Business Day. Interest Calculation. - -------------------- The Interest Period Interest Charge shall be the sum of the Daily Interest Charges in the Interest Period. The Daily Interest Charge on each Principal Advance shall be calculated as follows: Daily Balance X Interest Rate 360 The Interest Period shall be the period from the day following the last interest due date to the next interest due date. The Interest Rate is the rate elected by the Borrower for each Principal Advance. The maximum principal amount outstanding under this Note shall be limited to Four Million Dollars ($4,000,000). Pursuant to the Letter Agreement, there shall be due and payable from the Borrower to the Bank, and the Borrower shall immediately pay to the Bank, without demand, any amount by which the Debit Balance exceeds Four Million Dollars ($4,000,000). The term "Prime Rate" means the variable per annum rate of interest so designated from time to time by the Bank as its prime rate. The Prime Rate is a reference rate and does not necessarily represent the lowest or best rate being charged to any customer. The rate of interest hereunder shall change simultaneously and automatically, without further notice, upon the Bank's determination and designation from time to time of the Prime Rate. The Bank's determination and designation from time to time to the Prime Rate shall not in any way preclude the Bank from making loans to other borrowers at rates that are higher or lower than or different from the referenced rate. "LIBOR" shall mean, as applicable to any LIBOR Advance and LIBOR period applicable thereto, (i) a rate per annum (rounded upward, if necessary), to the nearest 1/32 of one percent) equal to the composite London Interbank Offered Rate which appears on the Telerate page 3750 as of 11:00 am. London time on the day that is two (2) London Banking Days preceding the first day of such LIBOR Period (or if not reported thereon, then as determined by Bank from another recognized source or interbank quotation) divided by (ii) a fraction (A) the numerator of which is one and (B) the denominator is the average of the daily rates (expressed as a decimal) for maximum reserve requirements which are, at any time rates (expressed as a decimal) of maximum reserve requirements which are, at any time, applicable during such LIBOR Period (including, without limitation, basic, supplemental, special, marginal and emergency reserves) under any regulation of the Board of Governors of the Federal Reserve System or other banking authority, domestic or foreign, as now or hereafter in effect, prescribed for eurocurrency funding (currently referred to as Eurocurrency Liabilities in Regulation D of such Board) to which the Bank (including any branch, affiliate, or other fronting office, making or holding a loan that accrues interest at a rate which refers to LIBOR) is subject, as now or hereafter in effect. "LIBOR Period" shall mean, with respect to any LIBOR Loan, the period commencing on the date on which the LIBOR Loan begins to bear interest at a rate tied to LIBOR in accordance herewith and ending one, two, or three month(s) thereafter, as appropriate, as selected by the Borrower pursuant hereto; provided however, (i) any LIBOR Period that would otherwise end on a day which is not a Banking Day shall be extended to the next Banking Day, unless such extension would carry such LIBOR Period into the next month, in which event such LIBOR Period shall end on the preceding Banking Day, (ii) any LIBOR Period that begins on the last Banking Day of a calendar month (or on a date for which there is no numerically corresponding day in the calendar month in which such LIBOR Period ends) shall end on the last Banking Day of a calendar month, and (iii) any LIBOR Period that would otherwise extend beyond the (Maturity Date) shall end on the (Maturity Date). "London Banking Day" shall mean any Banking Day on which commercial banks are open for international business (including dealing in U.S. dollar ($) deposits) in London, England and Philadelphia, Pennsylvania. "Cost of Funds" means the per annum rate of interest which Bank is required to pay, or is offering to pay, for wholesale liabilities, adjusted for reserve requirement and such other requirements as may be imposed by federal, state or local government and regulatory agencies, as determined by Sovereign Treasury Group, or its successors. The "LIBOR rate" and the "Cost of Funds rate" shall mean the rate provided to the Borrower as described in the Letter Agreement by the Bank upon any given day as such rate. Such rate shall consist of the LIBOR or Cost of Funds index as of such date, plus a margin to be determined by the Bank in its sole discretion. Any LIBOR rate or Cost of Funds rate shall be fixed for the duration of the election. All amounts outstanding under the Line which are not subject to the LIBOR rate or the Cost of Funds rate shall bear interest at a variable annual rate equal to the Borrower's Prime Rate as provided hereinabove. Notwithstanding the foregoing provisions, the Borrower may not convert existing advances to LIBOR advances or Cost of Funds advances if at any time either an Event of Default or a payment Default exists under the Loan Documents. As used herein, "LIBOR Advance" shall mean any amount outstanding under the Line as to which the Borrower has elected a LIBOR Rate, and "Cost of Funds Advances" shall mean any amount outstanding under the Line as to which the Borrower has elected a Cost of Funds rate. All computations of interest under this Note shall be made on the basis of a three hundred sixty (360) day year and the actual number of days elapsed. Late Charges: If a regularly scheduled payment is fifteen (15) days or more late, Borrower will be charged 5.000% of the unpaid portion of the regularly scheduled payment or $10.00, whichever is greater. If Bank demands payment of this Loan, and Borrower does not pay the Loan within fifteen (15) days after Bank's demand, Borrower will be charged either 5.000% of the unpaid principal plus accrued unpaid interest or $10.00, whichever is greater. Borrower shall not be obliged to pay and Bank shall not collect interest at a rate higher than the maximum permitted by law or the maximum that will not subject Bank to any civil or criminal penalties. If, because of the acceleration of maturity the payment of interest in advance or any other reason, Borrower is required, under the provisions of any Loan Documents or otherwise, to pay interest at a rate in excess of such maximum rate, the rate of interest under such provisions shall immediately and automatically be reduced to such maximum rate and any payment made in excess of such maximum rate, together with interest thereon at the rate provided herein from the date of such payment, shall be immediately and automatically applied to the reduction of the unpaid principal balance of this Note as of the date on which such excess payment was made. If the amount to be so applied to reduction of the unpaid principal balance exceeds the unpaid principal balance, the amount of such excess shall be refunded by Bank to Borrower. The Borrower agrees that the Bank may make loan advances to the Borrower upon verbal authority (which, if the Bank so requires, shall be followed by written confirmation) of any officer executing this Note on behalf of the Borrower or any other officer of the Borrower who is authorized in writing to borrow money from the Bank and may deliver such advances by direct deposit to any deposit account of the Borrower with the Bank or otherwise as may be authorized in the Letter Agreement. Notwithstanding anything to the contrary herein, the Bank may require written notice of requests for loan advances as may be provided in the Letter Agreement. All such advances shall represent binding obligations of the Borrower. The Borrower's "Debit Balance" shall mean the debit balance in an account on the books of the Bank, maintained in the form of a ledger card, computer records or otherwise in accordance with the Bank's customary practice and appropriate accounting procedures wherein there shall be recorded the principal amount of all advances made by the Bank to the Borrower, all principal payments made by the Borrower to the Bank hereunder, and all other appropriate debits and credits (the "Loan Account"). The Bank shall render to the Borrower a statement of account with respect to the Loan Account on a monthly basis. Such statement shall indicate the Borrower's then current Debit Balance and any interest amounts due and payable from the Borrower to Bank. Such statement may be based on estimates of the principal amount outstanding and the interest rate for the applicable payment period. Any required adjustments between such estimates and actual amounts shall be reflected in subsequent statements. The Borrower acknowledges that this Note is to evidence the Borrower's obligation to pay the Debit Balance, plus interest, as determined from time to time and that it shall continue to do so despite the occurrence of intervals when no Debit Balance exists because the Borrower has paid the previously existing Debit Balance in full. This Note is a DEMAND OBLIGATION. At the option of the Bank, this Note shall become immediately due and payable in full, without further demand or notice, on the earlier of (i) demand by the Bank, or (ii) the occurrence of an Event of Default (as defined below). If any of the following events of default shall occur ("Event of Default"): (a) default in the payment or performance of any of the Obligations or of any obligations of any Obligor to others for borrowed money or in respect of any extension of credit or accommodation: (b) failure of any representation or warranty, statement or information in any documents or financial statements delivered to the Holder for the purpose of inducing it to make or maintain any loan under this Note to be true and correct; (c) failure of the undersigned to file any tax return, or to pay or remit any tax, when due, unless the undersigned contests the particular tax in good faith, and also maintains adequate reserves to pay such tax, if unsuccessful in its action to contest; (d) failure to furnish the Holder promptly on request with financial information about, or to permit inspection by the Holder of books, records and properties to any Obligor; (e) any Obligor generally not paying its debts as they become due; (f) death, dissolution, termination of existence, insolvency, business failure, appointment of a receiver or other custodian of any part of the property of, assignment for the benefit of creditors by, or the commencement of any proceedings (except for an involuntary bankruptcy petition against any Obligor to which such Obligor files a proper answer thereto pursuant to Section 303(d) of the Bankruptcy Code (11 USC 303(d)) within ten (10) days of receipt of notice of said proceeding, which answer shall include a request that petitioning creditors post adequate bond under Section 303(e)(11 USC 303(e))) under any bankruptcy or insolvency laws by or against, any Obligor; (g) a material adverse change in the condition or affairs (financial or otherwise) of any Obligor which in the opinion of the Holder will impair its security or increase its risk including but not limited to any reduction of any Obligor's tangible net worth by more than 10% from its level at the previous fiscal year end or the occurrence of operating losses for any consecutive twelve month period; then the Holder shall give written notice of such default and if such default is not cured within five business days of delivery of such notice then immediately and automatically with respect to any Defaults set forth in clauses (e) and (f) above, and thereupon or at anytime thereafter with respect to each other Default (such Default not having been previously cured), at the option of the Holder, all Obligations of the Obligor shall become immediately due and payable without demand, and, if there is any collateral for the Obligations, the Holder shall then have in any jurisdiction where enforcement hereof is sought, in addition to all other rights and remedies the rights and remedies of a secured party under the Uniform Commercial Code as in effect in the State of New Hampshire. As used herein, "Obligation" means any obligation hereunder or otherwise of any Obligor to the holder whether direct or indirect, absolute or contingent, due or to become due, now existing or hereafter arising. The Borrower agrees to pay on demand all reasonable out-of-pocket costs of collection hereof, including reasonable attorneys' fees, whether or not any foreclosure or other action is instituted by the Holder in its discretion. All payments received will be applied first to interest, then to fees, and then to principal. As additional collateral, the Borrower grants (1) a security interest in, or pledges, assigns and delivers, to the Holder, as appropriate, all deposits, credits and other property now or hereafter due from the Holder to such Borrower and (2) the right to set-off and apply (and a security interest in said right), from time to time hereafter and without demand or prior notice of any nature, all, or any portion, of such deposits, credits and other property, against the indebtedness evidenced by this Note, whether the other collateral, if any, is deemed adequate or not. Borrower and Bank mutually hereby knowingly, voluntarily and intentionally waive the right to a trial by jury in respect of any claim based hereon, arising out of, under or in connection with this Note or any other documents executed in connection herewith or any course of conduct, course of dealing, statements (whether verbal or written) or actions of any party. This waiver constitutes a material inducement for Bank to accept this Note and make the Loan. No delay or omission on the part of the Holder in exercising any right, privilege or remedy shall impair such right, privilege or remedy or be construed as a waiver thereof or of any other right, privilege or remedy. No waiver of any right, privilege or remedy or any amendment to this Note shall be effective unless made in writing and signed by the Holder. Under no circumstances shall an effective waiver of any right, privilege or remedy on any one occasion constitute or be construed as a bar to the exercise of or a waiver of such right, privilege or remedy on any future occasion. The acceptance by the Holder hereof of and payment after any default hereunder shall not operate to extend the time of payment of any amount then remaining unpaid hereunder or constitute a waiver of any rights of the Holder hereof under this Note. All rights and remedies of the Holder, whether granted herein or otherwise, shall be cumulative and may be exercised singularly or concurrently, and the Holder shall have, in addition to all other rights and remedies, the rights and remedies of a secured party under the Uniform Commercial Code of New Hampshire. The Borrower waives, to the fullest extent permitted by law, presentment, notice, protest and all other demands and notices and assent (1) to any extension of the time of payment or any other indulgence, (2) to any substitution, exchange or release of collateral, and (3) to the release of any other person primarily or secondarily liable for the obligations evidenced hereby. This Note and the provisions hereof shall be binding upon the Borrower and the Borrower's heirs, administrators, executors, successors, legal representatives and assigns and shall inure to the benefit of the Holder, the Holder's heirs, administrators, executors, successors, legal representatives and assigns. This Note may not be amended, changed or modified in any respect except by a written document which has been executed by each party. This Note and all rights and obligations hereunder, including matters of construction, validity and performance, shall be governed by the laws of the State of New Hampshire. IN WITNESS WHEREOF, the Borrower, acting by and through its duly authorized officer, has executed this Promissory Note on this 25th day of September, 2000.

ADDENDUM A Prepayment Penalty: At any time that (i) the interest rate on the loan described in the Loan Documents is a fixed rate (e.g., a "LIBOR rate" or a "Cost of Funds rate") and (ii) the Bank in its sole discretion should determine that current market conditions can accommodate a prepayment request, the Borrower shall have the right at any time and from time to time to prepay the loan in whole (but not in part), and the Borrower shall pay to the bank a yield maintenance fee in an amount computed as follows. The current rate for United States Treasury securities (Bills on a discounted basis shall be converted to a bond equivalent) with a maturity date closest to the maturity date of the term chosen pursuant to the fixed rate election as to which the prepayment is made shall be subtracted from the "LIBOR rate" or "Cost of Funds rate" component, as applicable, of the fixed rate in effect at the time of prepayment. If the result is zero or a negative number, there shall be no yield maintenance fee. If the result is a positive number, then the resulting percentage shall be multiplied by the amount of the principal balance being prepaid. The resulting amount shall be divided by 360 and multiplied by the number of days remaining in the term chosen pursuant to the fixed rate election as to which the prepayment is made. Said amount shall be reduced to present value calculated by using the number of days remaining in the designated term and using the above referenced United States Treasury security rate and the number of days remaining in the term chosen pursuant to the fixed rate election as to which the prepayment is made. The resulting amount shall be the yield maintenance fee due to the Bank upon prepayment of the fixed rate Loan. Each reference in the paragraph to "fixed rate election" shall mean the election by the Borrower pursuant to the Letter Agreement of near or even date. If by reason of an Event of Default the Bank elects to declare the Loan to be immediately due and payable, then any yield maintenance fee with respect to the Loan shall become due and payable in the same manner as though the Borrower had exercised such right of repayment.

Exhibit H-2

                             Proposed Form of Notice

     Unitil  Corporation  ("Unitil"),  of 6  Liberty  Lane  West,  Hampton,  New
Hampshire 03842- 1720, a registered holding company,  has filed a post-effective
amendment  under  Sections  6(b), 7, 9(a), 10 and 12(b) of the Public  Utilities
Holding  Company  Act of 1935,  as  amended  ("Act")  and  Rules  43,  45 and 52
thereunder to an application-declaration previously filed under the Act.

     On June 9, 2000, Unitil 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")  (Unitil and the
Subsidiaries  are  collectively  referred  to  as  the  "Applicants"),  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").

     Applicants  now seek approval 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.

     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  additional  borrowing
authority for Fitchburg.

     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.
