Part III. The disclosures made in the System companies' most recent proxy
statement and annual report on Form 10-K with respect to items (a) through (f)
follow:

(a)  COMPENSATION OF DIRECTORS AND EXECUTIVE OFFICERS

                             DIRECTORS' COMPENSATION

In 2002, members of the Board of Directors who are not officers of Unitil or any
of its subsidiaries received an annual retainer fee of $7,000 in cash and $5,500
in Unitil Common Stock, as well as $500 for each Board Meeting attended. Members
of the Executive Committee who are not officers of Unitil or any of its
subsidiaries received an annual retainer fee of $3,000 and $400 for each meeting
attended. The Chairman of the Executive Committee received an annual retainer
fee of $15,000, and $400 for each meeting attended. Members of the Audit
Committee and Compensation Committee received an annual retainer fee of $1,000
and $400 for each meeting attended. The Chairman of the Audit Committee and the
Chairman of the Compensation Committee received an annual retainer fee of
$2,000, respectively, and $400 for each meeting attended. Those Directors of
Unitil who also serve as Directors of FG&E and Unitil Energy Systems, Inc. and
who are not officers of Unitil or any of its subsidiaries received a meeting fee
of $100 per subsidiary meeting attended and no annual retainer fee from FG&E or
Unitil Energy Systems, Inc. All Directors are entitled to reimbursement of
expenses incurred in connection with attendance at meetings of the Board of
Directors and any Committee on which they serve.

As part of the Company's overall support for charitable institutions, the
Company has a program that provides a perpetual gift of $1,000 annually to the
Greater Seacoast United Way ("United Way") on behalf of each Director who
retires from the Board. The Director(s) receive no financial benefit from this
program as the charitable deductions accrue solely to the Company. No Directors
retired from the Board in 2002.

In 1999, the Board of Directors approved the Unitil Corporation Directors'
Deferred Compensation Plan ("Deferred Plan") for the purpose of allowing
non-employee members of the Board to defer payment of all or a specified part of
compensation for services performed as a Director. The Deferred Plan is
administered by the Compensation Committee and stipulates that eligible
Directors may elect to defer all or a portion of their cash retainer and meeting
fees. Separate accounts are maintained for each Director participant, which are
an unfunded liability of the Company. Additionally, accounts are credited
monthly with interest based on the current rate of 60-month Treasury bills.
Funds contributed and interest credited is tax deferred until withdrawn from the
Deferred Plan. Director participants may elect to withdraw funds from the
Deferred Plan after a fixed amount of time, upon resignation or retirement from
the Board, upon death or disability, or upon a Change in Control. Withdrawals
may be taken in cash, either in one lump sum or in a series of installments.
During 2002, no Directors participated in the Deferred Plan.

NOTES:

(1)  The KESOP was approved by shareholders in July, 1989. Options were granted
     between January, 1989 and November, 1997.
(2)  The 1998 Option Plan was adopted by the Board of Directors of the Company
     in December 1998. Options were granted in March, 1999, January, 2000, and
     January, 2001.

Key Employee Stock Option Plan (KESOP)

The KESOP was adopted by the Board of Directors on January 17, 1989, and
approved by the Company's shareholders on July 11, 1989. The KESOP authorized
the Compensation Committee to provide in the award agreements that the
participant's right to exercise the options provided for therein will be
accelerated upon the occurrence of a "Change in Control" of Unitil. The term
"Change in Control" is defined in substantially the same manner as in the
Severance Agreements, as described on page 18. Award agreements entered into
with participants in the KESOP contain such a "Change in Control" provision.
Award agreements also provide that, upon the exercise of an option on or after a
Change in Control, Unitil shall pay to the optionee, within five business days,
a lump sum cash amount equal to the economic benefit of the optionee's
outstanding options and associated dividend equivalents that the optionee would
have received had the option remained unexercised until the day preceding the
expiration of the grant.

Upon the exercise of any option by an employee and upon payment of the option
price for shares of Unitil Common Stock as to which the option was granted (the
"Primary Shares"), Unitil will cause to be delivered to such employee (i) the
Primary Shares and (ii) the number of shares of Unitil Common Stock (the
"Dividend Equivalent Shares") equal to the dollar amount of dividends which
would have been paid on the Primary Shares (and previously accrued Dividend
Equivalent Shares) had they been outstanding, divided by the fair market value
of Unitil Common Stock determined as of the record date for each dividend. All
options granted under the KESOP, excluding Mr. Schoenberger's options, described
below, were granted in 1989 with an expiration date of 1999. All such options
were exercised prior to March 7, 1999.

In accordance with the terms of Mr. Schoenberger's 1997 employment agreement, on
November 3, 1997, 25,000 options to purchase shares of Company stock were
granted to Mr. Schoenberger under the KESOP. The options granted to Mr.
Schoenberger became exercisable on November 3, 1998. In 1998, the Compensation
Committee extended the expiration date of Mr. Schoenberger's options until
November 3, 2007. As of December 31, 2002, Mr. Schoenberger's 25,000 options
were the only options outstanding under the KESOP and Mr. Schoenberger is the
only participant in the KESOP.

The Unitil Corporation 1998 Stock Option Plan (Option Plan)

In December, 1998, the Board of Directors adopted the Unitil Corporation 1998
Stock Option Plan ("Option Plan"). The purpose of the Option Plan was to provide
an incentive to key employees and directors of Unitil and its affiliates who are
in a position to contribute materially to the long-term success of Unitil and/or
its affiliates, to increase their interest in the welfare of Unitil and its
affiliates, and to attract and retain employees and directors of outstanding
ability. The Company had originally intended to grant stock options under the
Option Plan each year through March 1, 2004, to certain employees and directors,
for the purchase of up to 350,000 shares of Unitil Common Stock.

On January 16, 2003, the Board of Directors terminated the Option Plan upon the
recommendation of the Compensation Committee. The Compensation Committee also
recommended that the Company adopt a Restricted Stock Plan to replace the Option
Plan. (See below as to the approval of a "Restricted Stock Plan".) The Option
Plan will remain in effect solely for the purposes of the continued
administration of all options currently outstanding under the Option Plan. No
further grants of options will be made thereunder.

Stock options granted under the Option Plan entitle the holders of those options
to purchase up to the number of shares of common stock specified in the grant at
a price established by the Committee. All grants were issued at 100% of market
value at the time of the grant. Each option grant has a vesting period of three
years and each grant expires ten years after the date of grant.

The Compensation Committee is charged with the administration of the Option
Plan. The Option Plan authorizes the Compensation Committee to provide in the
award agreements that the participant's right to exercise the options provided
for therein will be accelerated upon the occurrence of a Change in Control of
Unitil. The term "Change in Control" is defined in substantially the same manner
as in the Severance Agreements, as described on page 18. All of the award
agreements entered into with participants in the Option Plan to date contain
such a "Change in Control" provision.

To date, grants were made to certain management employees in March, 1999,
January, 2000, and January 2001. No grants were made to any Option Plan
participants in 2002.

Non-Equity Compensation Plan Benefit Information

The Company has in place, since December, 1998, a Management Incentive Plan and
an Employee Incentive Plan to provide cash incentive payments that are tied
directly to achievement of the Company's strategic goals. Annual goals are
established each year by the Board of Directors and payment of awards is made in
February of the year following achievement of the goals. Target incentive
payments have been established that vary based upon the grade level of each
position. Actual awards can be less than or greater than the target payout
depending upon actual results achieved.

Unitil maintains a tax-qualified defined benefit pension plan and related trust
agreement (the "Retirement Plan") that provides retirement annuities for
eligible employees of Unitil and its subsidiaries. Since the Retirement Plan is
a defined benefit plan, no amounts were contributed or accrued specifically for
the benefit of any officer of Unitil under the Retirement Plan. Directors of
Unitil who are not and have not been officers of Unitil or any of its
subsidiaries are not eligible to participate in the Retirement Plan.

The table below sets forth the estimated annual benefits (exclusive of Social
Security payments) payable to participants in the specified compensation and
years of service classifications, assuming continued active service until
retirement. The average annual earnings used to compute the annual benefits are
subject to a $200,000 limit.

The present formula for determining annual benefits under the Retirement Plan's
life annuity option is (i) 2% of average annual salary (average annual salary
during the five consecutive years out of the last twenty years of employment
that give the highest average salary) for each of the first twenty years of
benefit service, plus (ii) 1% of average annual salary for each of the next ten
years of benefit service and (iii) 1/2% of average annual salary for each year
of benefit service in excess of thirty, minus (iv) 50% of age 65 annual Social
Security benefit (as defined in the Retirement Plan), and (v) any benefit under
another Unitil retirement plan of a former employer for which credit for service
is given under the Retirement Plan. A participant is eligible for early
retirement at an actuarially reduced pension upon the attainment of age 55 with
at least 15 years of service with Unitil or one of its subsidiaries. A
participant is 100% vested in his benefit under the Retirement Plan after five
years of service with Unitil or one of its subsidiaries. As of January 1, 2003,
Messrs. Schoenberger, Dalton, Baratta, Gantz and Collin had 5, 35, 5, 19 and 14
credited years of service, respectively, under the Retirement Plan.

Unitil also maintains a Supplemental Executive Retirement Plan ("SERP"), a
non-qualified defined benefit plan. SERP provides for supplemental retirement
benefits to executives selected by the Board of Directors. At the present time,
Messrs. Schoenberger and Dalton are eligible for SERP benefits upon attaining
normal or early retirement eligibility. Annual benefits are based on a
participant's final average earnings less the participant's benefits payable
under the Retirement Plan, less other retirement income payable to such
participant by Unitil or any previous employer and less income that a
participant receives as a primary Social Security benefit. Early retirement
benefits are available to a participant, with the Unitil Board's approval, if
the participant has attained age 55 and completed 15 years of service. Should a
participant elect to begin receiving early retirement benefits under SERP prior
to attaining age 60, the benefits are reduced by 5% for each year that
commencement of benefits precedes attainment of age 60. If a participant
terminates employment for any reason prior to retirement, the participant will
not be entitled to any benefits. Under the SERP, Mr. Schoenberger would be
entitled to receive an annual benefit of $51,700, assuming normal retirement at
age 65 and that his projected final average earnings are equal to the average of
his respective three consecutive years of highest compensation prior to
retirement. On Mr. Dalton's retirement date of April 1, 2003, at age 62, his
annual SERP benefit will be $41,341.


Restricted Stock Plan

At its January, 2003, meeting, the Board of Directors approved the
recommendation of the Compensation Committee to adopt a Restricted Stock Plan
(the "Plan") to replace the Unitil Corporation 1998 Stock Option Plan, which was
terminated by the Board at the same January, 2003, meeting. The Compensation
Committee made the recommendation in part in the belief that the Plan would
better tie executive officer compensation to the long-term success of the
Company through stock ownership in the Company. Participants in the Plan are
selected by the Compensation Committee from the eligible Participants to receive
an annual award of restricted shares of Company Common Stock. The size of the
award is dependent upon the Company meeting certain strategic objectives set by
the Board of Directors.

The Plan was approved by the Board, and ratified by the shareholders of the
Company at the 2003 Annual Meeting of Shareholders held on April 17, 2003.


                                       12




The objectives of the Plan are to optimize the profitability and growth of the
Company through incentives that are consistent with the Company's goals and that
link the personal interests of Participants to those of the Company's
shareholders, to attract and retain employees and directors of outstanding
ability, and to promote teamwork among participants. The Plan shall remain in
effect, subject to the right of the Board to amend or terminate the Plan at any
time, until all shares subject to it shall have been purchased or acquired
according to the Plan's provisions.

Administration of the Plan
The Plan is administered by the Compensation Committee. Except as limited by law
or by the Articles of Incorporation or the By-laws of the Company, and subject
to the provisions of the Plan, the Compensation Committee shall have full power
to select the persons who shall participate in the Plan; determine the sizes of
awards; determine the terms and conditions of awards in a manner consistent with
the Plan; construe and interpret the Plan and any agreement or instrument
entered into under the Plan as they apply to participants; establish, amend, or
waive rules and regulations for the Plan's administration as they apply to
participants; and, subject to the provisions of the Plan, amend the terms and
conditions of any outstanding award to the extent such terms and conditions are
within the discretion of the Compensation Committee as provided in the Plan.

Types of Awards Under the Plan
Awards under the Plan will be granted in the form of restricted shares of the
Company's Common Stock. Awards shall be evidenced by an Award Agreement, entered
into by the participant and the Company, setting forth the terms and provisions
applicable to the award. The Company anticipates granting awards under the Plan
on an annual basis.

Criteria Used to Determine Awards
Awards under the Plan will vary each year based on the achievement of annual
performance objectives that directly correlate with the annual performance
objectives as defined by the Unitil Management Incentive Plan ("Incentive
Plan"). The Incentive Plan is described more fully in Item 6, Part III, section
(a) above (see "Other Compensation Arrangements"). Whereas the Incentive Plan
provides cash incentive payments that are tied directly to achievement of the
Company's strategic goals, the Plan will provide awards of restricted shares of
Company Common Stock that are tied directly to achievement of the Company's
strategic goals. Annual performance objectives are established each year by the
Board of Directors. The percentage of the target award that a Plan participant
receives is also based upon subjective evaluations by the Compensation
Committee, such as management's performance in capitalizing on unplanned
opportunities and responding to unforeseen problems. Target grant awards have
been established that vary based upon the grade level of each participant's
position in the Company. Actual awards can be less than or greater than the
target grant depending upon actual results achieved.

Key Components of the Plan
Awards will fully vest over a period of four (4) years (the "Period of
Restriction") at a rate of 25% each year. During the Period of Restriction, the
restricted shares may not be sold, transferred, pledged, assigned or otherwise
alienated or hypothecated. Prior to the end of the Period of Restriction, the
restricted shares shall be subject to forfeiture if the participant ceases to be
employed by the Company other than due to the participant's death. Subject to
restrictions under applicable law or as may be imposed by the Company,
restricted shares underlying each Award made under the Plan shall become freely
transferable by the Participant after the last day of the applicable Period of
Restriction.

The Company shall retain the certificates representing the restricted shares in
the Company's possession until such time as all conditions and/or applicable
restrictions have been satisfied.

During the Period of Restriction, participants holding restricted shares granted
under the Plan shall have all the rights of a shareholder of the Company,
including the right to vote the restricted shares during the Period of
Restriction. Any cash dividends paid on the Restricted Shares during the Period
of Restriction may be credited to the participant's account, and may be subject
to such restrictions as the Compensation Committee may determine to be
appropriate and as are set forth in the particular Award Agreement. In the event
any non-cash dividends or other distributions, whether in property, or in stock
of another company, are paid on any restricted shares during the Period of
Restriction, such non-cash dividends or other distributions shall be retained by
the Company until such time as the Period of Restriction has lapsed. In the
event of forfeiture of the restricted shares, such non-cash dividend or other
distributions shall be retained by the Company.


                                       13




Awards may be grossed-up to offset the participant's tax obligation in
connection with the award. This gross-up feature is intended to prevent a
participant from having to sell a portion of the shares granted in the award or
previous awards in order to pay the taxes on the award, which would be a direct
contradiction to one of the stated objectives of the Plan, which is to encourage
stock ownership in the Company. The Compensation Committee will take into
account the value of the gross-up feature and reduce the size of the awards
accordingly.

Upon the occurrence of a Change in Control, unless otherwise specifically
prohibited under applicable laws, or by the rules and regulations of any
governing governmental agencies or national securities exchanges, any
restrictions and transfer limitations imposed on Restricted Shares shall
immediately lapse. The term "Change in Control" is defined in substantially the
same manner as in the Severance Agreements, as described on page 18.

The Compensation Committee shall have the authority to impose additional
conditions and/or restrictions on any shares of restricted stock granted
pursuant to the Plan as it may deem advisable.

Number of Shares Subject to Awards
The maximum number of shares of Restricted Stock available for awards to
participants under the Plan is 177,500. The maximum aggregate number of shares
of Restricted Stock that may be awarded in any one calendar year to any one
participant is 20,000. In the event of any change in capitalization of the
Company, the Compensation Committee is authorized to make proportionate
adjustments to prevent dilution or enlargement of rights, including, without
limitation, an adjustment in the maximum number and kinds of shares available
for awards and in the annual award limit.

Persons Eligible to Participate and Basis For Participation in the Plan
Persons eligible to participate in the Plan include all employees, directors and
consultants of the Company, its subsidiaries and its affiliates. The Company
currently has 316 employees, nine independent non-employee Directors, and
several consultants. The basis for participation in the Plan is discretionary on
the part of the Compensation Committee.

Amendment or Termination of the Plan
The Board may at any time amend or terminate the Plan or any award granted under
the Plan in whole or in part, that no amendment that requires shareholder
approval in order for the Plan to continue to comply with any applicable tax or
securities laws or regulations, or the rules of any securities exchange on which
the securities of the Company are listed, shall be effective unless such
amendment shall be approved by the requisite vote of shareholders of the Company
and that no such amendment or termination shall adversely affect any award
previously granted under the Plan without the consent of the participant.

The table below provides information with respect to the projected value of
awards which may be granted annually to the indicated individuals and groups
under the Plan.

NOTES:
(1)  Mr. Dalton and Mr. Baratta are not included in the table since awards under
     the Plan will only be made subsequent to the retirement dates of Mr. Dalton
     and Mr. Baratta.

(2)  For illustrative purposes in the table, the per share market value is
     calculated using the average of the daily averages of the high and low
     sales prices of the Company's Common Stock for the last five trading days
     on which the Company's Common Stock was traded prior to and including the
     record date, February 20, 2003, for a value of $25.243 per share. Actual
     market value for each award granted under the Plan will be the closing
     price of Unitil Common Stock on the day the award becomes vested.

(3)  To account for the tax gross-up feature of the Plan, the dollar value for
     each participant is calculated by dividing the market value of the Award by
     0.6535.

(4)  The number of shares shown in the table is the number of shares which the
     Compensation Committee has tentatively decided to grant to the named
     individuals and groups if shareholders approve the Plan.

(c)  TRANSACTIONS WITH SYSTEM COMPANIES - None

(d)  INDEBTEDNESS TO SYSTEM COMPANIES - None

(e)  OTHER BENEFITS

Unitil and certain subsidiaries maintain severance agreements (the "Severance
Agreements") with certain management employees, including Executive Officers.
The Severance Agreements are intended to help assure continuity in the
management and operation of Unitil and its subsidiaries in the event of a
proposed "Change in Control". Each Severance Agreement only becomes effective
upon the occurrence of a Change in Control of Unitil as defined in the Severance
Agreements. If an employee's stipulated compensation and benefits, position,
responsibilities and other conditions of employment are reduced during the
thirty-six month period following a Change in Control, the employee is entitled
to a severance benefit.

The severance benefit is a lump sum cash amount equal to (i) the present value
of three years' base salary and bonus; (ii) the present value of the additional
amount the employee would have received under the Retirement Plan if the
employee had continued to be employed for such thirty-six month period; (iii)
the present value of contributions that would have been made by Unitil or its
subsidiaries under the 401(k) if the employee had been employed for such
thirty-six month period; and (iv) the economic benefit on any outstanding Unitil
stock options and associated dividend equivalents, if applicable, assuming such
options remained unexercised until the day preceding the expiration of the
grant, including the spread on any stock options that would have been granted
under the Option Plan if the employee had been employed for such thirty-six
month period. Each Severance Agreement also provides for the continuation of all
employee benefits for a period of thirty-six months, commencing with the month
in which the termination occurred. In addition, pursuant to each Severance
Agreement, Unitil is required to make an additional payment to the employee
sufficient on an after-tax basis to satisfy any additional individual tax
liability incurred under Section 280G of the Internal Revenue Code of 1986, as
amended, with respect to such payments.

The Company entered into an initial employment agreement with Mr. Schoenberger
on November 1, 1997. Upon the expiration of the 1997 Agreement, the Company
entered into a second employment agreement ("the 2000 Agreement") with Mr.
Schoenberger on November 1, 2000. The term of the 2000 Agreement is for three
years with an expiration date of October 31, 2003. Under the terms of the 2000
Agreement, Mr. Schoenberger will receive an annual base salary of $292,000,
which is subject to annual review by the Board for discretionary periodic
increases in accordance with the Company's compensation policies. In 2002, Mr.
Schoenberger's base salary was $304,000. Mr. Schoenberger is entitled to
continued participation in the Company's SERP, Executive Supplemental Life
Insurance Program and all other employee benefit plans made available by the
Company. The 2000 Agreement provides that Mr. Schoenberger shall participate in
the Management Incentive Plan, above (see Item 6, Part III, section (a) "Other
Compensation Arrangements"), and also in and the Option Plan, above (see Item 6,
Part III, section (a) "The Unitil Corporation 1998 Stock Option Plan"), or any
stock option or similar plan of the Company. The agreement also provides that
the Severance Agreement, entered into on February 6, 1998, by and between Mr.
Schoenberger and the Company, remain in effect. The Severance Agreement is more
fully described above (see Item 6, Part III, section (e) "Other Benefits"). The
2000 Agreement also provides that the Company, by action of the Board, may
terminate Mr. Schoenberger's employment for any reason. If Mr. Schoenberger's
employment is terminated by the Company during the term of the 2000 Agreement
for any reason other than cause, death or disability, or if Mr. Schoenberger
terminates his employment because of a constructive termination, the Company
shall pay Mr. Schoenberger a combination of (i) base pay at the rate in effect
on the date of employment termination, (ii) an annual amount equal to the
average of the annual bonus amounts received by Mr. Schoenberger in the two
calendar years preceding the year in which termination occurs, and (iii)
benefits, in each case for a period of two years following the date of
termination. If during such two-year period Mr. Schoenberger shall secure
full-time employment, the Company's obligation to provide benefits shall cease.
All such payments described above will be made in accordance with the Company's
regular payroll policies.

(f)  RIGHTS TO INDEMNITY

Unitil Corporation (the Corporation) shall indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal,


                                       17




administrative or investigative, by reason of the person's having served as, or
by reason of the person's alleged acts or omissions while serving as a director,
officer, employee or agent of the Corporation, or while serving at the request
of the Corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, against
expenses, including attorney's fees, judgments, fines and amounts paid in
settlement or otherwise actually and reasonably incurred by him in connection
with the action, suit or proceeding, if the person acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
the Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful, said indemnification to be
to the full extent permitted by law under the circumstances, including, without
limitation, by all applicable provisions of the New Hampshire Business
Corporation Act ("the Act").

Any indemnification under this Article shall be made by the Corporation with
respect to Directors or other persons after a determination that the person to
be indemnified has met the standards of conduct set forth in the Act, such
determination to be made by the Board of Directors, by majority vote of a
quorum, or by other persons authorized to make such a determination under the
Act.

The right of indemnification arising under this Article is adopted for the
purpose of inducing persons to serve and to continue to serve the Corporation
without concern that their service may expose them to personal financial harm.
It shall be broadly construed, applied and implemented in light of this purpose.
It shall not be exclusive of any other right to which any such person is
entitled under any agreement, vote of the stockholders or the Board of
Directors, statute, or as a matter of law, or otherwise, nor shall it be
construed to limit or confine in any respect the power of the Board of Directors
to grant indemnity pursuant to any applicable statutes or laws of The State of
New Hampshire. The provisions of this Article are separable, and, if any
provision or portion hereof shall for any reason be held inapplicable, illegal
or ineffective, this shall not affect any other right of indemnification
existing under this Article or otherwise. As used herein, the term "person"
includes heirs, executors, administrators or other legal representatives. As
used herein, the terms "Director" and "officer" include persons elected or
appointed as officers by the Board of Directors, persons elected as Directors by
the stockholders or by the Board of Directors, and persons who serve by vote or
at the request of the Corporation as directors, officers or trustees of another
organization in which the Corporation has any direct or indirect interest as a
shareholder, creditor or otherwise.

The Corporation may purchase and maintain insurance on behalf of any person who
was or is a Director, officer or employee of the Corporation or any of its
subsidiaries, or who was or is serving at the request of the Corporation as a
fiduciary of any employee benefit plan of the Corporation or any subsidiary,
against any liability asserted against, and incurred by, such person in any such
capacity, or arising out of such person's status as such, whether or not the
Corporation would have the power to indemnify such person against such liability
under the provisions of the Act. The obligation to indemnify and reimburse such
person under this Article, if applicable, shall be reduced by the amount of any
such insurance proceeds paid to such person, or the representatives or
successors of such person.

Unitil maintains a tax-qualified defined benefit pension plan and related trust
agreement (the "Retirement Plan"), which provides retirement annuities for
eligible employees of Unitil and its subsidiaries. Since the Retirement Plan is
a defined benefit plan, no amounts were contributed or accrued specifically for
the benefit of any officer of Unitil under the Retirement Plan. Directors of
Unitil who are not and have not been officers of Unitil or any of its
subsidiaries are not eligible to participate in the Retirement Plan.

Exhibit D.    Tax Allocation Agreement

AGREEMENT made as of September 10, 1985, among Concord Electric Company, a New
Hampshire corporation, Exeter & Hampton Electric Company, a New Hampshire
corporation, UNITIL Service Corp., a New Hampshire corporation, and UNITIL Power
Corp., a New Hampshire corporation, and UNITIL Corporation ('UNITIL"), a New
Hampshire corporation, ("AFFILIATE" companies or collectively, the
"AFFILIATES"). Whenever it is intended to include UNITIL in the context of the
affiliated group, the term "CONSOLIDATED AFFILIATE" or "CONSOLIDATED AFFILIATES"
may be used, and when reference is to the affiliated group as a collective tax
paying unit the term "Group" may be used.

WHEREAS, UNITIL owns at least 80 percent of the issued and outstanding shares of
each class of voting common stock of each of the AFFILIATES: each of the
CONSOLIDATED AFFILIATES is a member of the affiliated group within the meaning
of section 1504 of the Internal Revenue Code of 1954, as amended (the "Code"),
of which UNITIL is the common parent corporation; and UNITIL proposes to include
each of the AFFILIATES in filing a consolidated income tax return for the
calendar year 1985;

NOW, THEREFORE, UNITIL and the AFFILIATES agree as follows:

1. Consolidated Return Election. If at any time and from time to time UNITIL so
elects, each of the AFFILIATES will join in the filing of a consolidated Federal
income tax return for the calendar year 1985 and for any subsequent period for
which the Group is required to file such a return. UNITIL and its affiliates
agree to file such consents, elections and other documents and to take such
other action as may be necessary or appropriate to carry out the purposes of
this Section 1. Any period for which any of the AFFILIATES is included in a
consolidated Federal income tax return filed by UNITIL is referred to in the
Agreement as a "Consolidated Return Year".

2. AFFILIATES' Liability to UNITIL for Consolidated Return Year. Prior to the
filing of each consolidated return by UNITIL, each of the AFFILIATES included
therein shall pay to UNITIL the amount, if any, on the Federal income tax for
which the AFFILIATES would have been liable for that year, computed in
accordance with Treasury Regulations, section 1.1552-1(a)(2)(ii) as though that
AFFILIATE had filed a separate return for such year, giving the effect to any
net operating loss carryovers, capital loss carryovers, investment tax credit
carryovers, foreign tax carryovers or other similar items, incurred by that
AFFILIATE for any period ending on or before the date of this Agreement.

The foregoing allocation of Federal income tax liability is being made in
accordance with Treasury Regulations, sections 1.1552-1(a)(2) and
1.1502-33(d)(2)(ii), and no amount shall be allocated to any CONSOLIDATED
AFFILIATE in excess of the amount permitted under Treasury Regulations, section
1.1502-33(d)(2)(ii). Accordingly, after taking into account the allocable
portion of the Group's Federal income tax liability, no amount shall be
allocated to any CONSOLIDATED AFFILIATE in excess of the amount permitted in
accordance with Treasury Regulations, section 1.1502-33(d)(2)(ii).

3. UNITIL Liability to Each Affiliate for Consolidated Return Year. If for any
Consolidated Return Year, any AFFILIATE included in the consolidated return
filed by UNITIL for such year has available a net operating loss, capital loss,
foreign tax credit, investment tax credit or similar items (computed by taking
into account carryovers of such items from periods ending on or before the date
of this Agreement) that reduces the consolidated tax liability of the Group
below the amount that would have been payable if that AFFILIATE did not have
such item available, UNITIL shall pay the amount of the reduction attributable
to such AFFILIATE PRIOR TO THE FILING of the consolidated return for such year.

The amount of the reduction shall be equal to a portion of the excess of (i) the
total of the separate return tax liabilities of each of the CONSOLIDATED
AFFILIATES computed in accordance with Section 2 of this Agreement, over (ii)
the Federal income tax liability of the Group for the year. The portion of such
reduction attributable to an AFFILIATE shall be computed by multiplying the
total reduction by a fraction, the numerator of which is the value of the tax
benefits contributed by the AFFILIATE to the Group and the denominator of which
is the value of the total value of such benefits contributed by all CONSOLIDATED
AFFILIATES during the year.


                                       34




For purposes of the foregoing paragraph a deduction of credit generated by a
CONSOLIDATED AFFILIATE which is in excess of the amount required to eliminate
its separate tax return liability but which is utilized in the computation of
the Federal income tax liability of the Group shall be deemed to be a tax
benefit contributed by the CONSOLIDATED AFFILIATE to the Group. The value of a
deduction which constitutes such a benefit shall be determined by applying the
current corporate income tax rate, presently 46 percent, to the amount for the
deduction. The value of a credit that constitutes such a benefit shall be the
tax savings, currently 100 percent thereof. The value of capital losses used to
offset capital gains shall be computed at the then current rate applicable to
capital gains for corporations.

4. Payment of Estimated Taxes. Prior to the paying and filing of estimated
consolidated tax declaration by UNITIL, each of the AFFILIATES included in such
estimated tax declaration shall pay to UNITIL the amount, if any, of the
estimated Federal income tax for which the AFFILIATE would have been liable for
that year, computed as though that AFFILIATE had filed a separate estimated tax
declaration for such year.

5. Tax Adjustments. In the event of any adjustments to the consolidated tax
return as filed (by reason of an amended return, a claim for refund of an audit
by the Internal Revenue Service), the liability, if any, of each of the
AFFILIATES under Sections 2, 3, and 4 shall be redetermined to give effect to
any such adjustment as if it had been made as part of the original computation
of tax liability, and payments between UNITIL and the appropriate AFFILIATES
shall be made within 120 days after any such payments are made or refunds are
received, or, in the case of contested proceedings, within 120 days after a
final determination of the contest.

Interest and penalties, if any, attributable to such an adjustment shall be paid
by each AFFILIATE to UNITIL in proportion to the increase in such AFFILIATE'S
separate return tax liability that is required to be paid to UNITIL, as computed
under Section 2.

6. Subsidiaries of Affiliates. If at any time, any of the AFFILIATES acquire or
creates one or more subsidiary corporations that are includable corporations of
the Group, they shall be subject to this Agreement and all references to the
AFFILIATES herein shall be interpreted to include such subsidiaries as a group.

7. Successors. This Agreement shall be binding on and inure to the benefit of
any successor, by merger, acquisition of assets or otherwise, to any of the
parties hereto (including but not limited to any successor of UNITIL or any of
the AFFILIATES succeeding to the tax attributes of such corporation under
Section 381 of the Code) to the same extent as if such successor had been an
original party to this Agreement.

8. Affiliates' Liability for Separate Return Years. If any of the AFFILIATES
leaves the Group and files separate Federal income tax returns, within 120 days
of the end of each of the first fifteen taxable years for which it files such
returns, it shall pay to UNITIL the excess, if any, of (A) Federal income tax
that such AFFILIATE would have paid for such year (on a separate return basis
giving the effect to its net operating loss carryovers) if it never had been a
member of the Group, over (B) the amount of Federal income tax such AFFILIATE
has actually paid or will actually pay for such years.

9. Examples of Calculations. Attached hereto and made part hereof , as "Appendix
A to Tax Sharing Agreement By and Between UNITIL Corporation and Its Affiliated
Companies", are illustrated examples of the matters contained herein.




In witness whereof, the duly authorized representatives of the parties hereto
have set their hands this tenth day of September, 1985.

                       APPENDIX A TO TAX SHARING AGREEMENT
                    BY AND BETWEEN UNITIL CORPORATION AND ITS
                              AFFILIATED COMPANIES


The allocation agreement follows the Internal Revenue Service Regulations for
"basic" and "supplemental" allocation of consolidated return liability and
benefits.

The "basic" method used to allocate UNITIL'S liability shown on the consolidated
return is provided by Internal Revenue Code Section 1552(a) and provides for
allocation based on the amount of tax liability calculated on a separate return
basis.

The "supplemental" method provides that the tax savings of credits and
deductions in excess of the amount of the individual company can use, but which
can be used in consolidations, is allocated among the members supplying the
savings and the benefiting members reimburse them.

For example, assume that a three-member group has consolidated tax liability of
$200,000 and $100,000 respectively. The individual members, A, B, and C have
separate return taxable income (loss) of $150,000, $100,000, and $(50,000) and
the individual members have separate return liabilities of $75,000, $50,000, and
none, respectively. (Loss members are deemed to have a zero tax liability.)
Under the proposed method, the Individual tax liability and benefit is allocated
as follows:



      Member                                        A                  B                C

Taxable Income (Loss)                               $150,000           $100,000       $(50,000)

Regulation 1.1502-33(d) provides the "supplemental" method of allocating tax
liability in order to permit members to receive reimbursement for contributing
tax deductions or credits to the group. The method adopted by the Company and
outlined at Regulation 1.1502-33(2)(ii) provides for immediate reimbursement for
the tax year involved. The steps are as follows:

(1) Tax liability is allocated to the members by the basic method outlined
above.
(2) Each member with a separate company tax will be allocated 100% of the excess
of its separate return liability over its share of the consolidated liability
under step (1). (3) The amounts allocated to benefiting members under Step 2 are
credited to the members supplying the capital losses, deductions, credits or
other items to which the savings are attributable. For this purpose an amount
generated by a member which is in its own separate return tax liability and
which is utilized in the computation of the Federal income tax liability of the
group shall be deemed to be a tax benefit contributed by the member to the
group.

In some years the Step 2 savings to be credited may be less than the total tax
savings items available for use. In such a case, the savings shall be attributed
to tax savings items in the order that they are used on the consolidated return
and in an amount equal to the savings actually realized.

Under this method, capital losses would normally be used first to the extent
there are capital gains, since these items are netted in order to reach income,
and are used before any deductions or credits are taken into account. The value
of the capital loss would be the current rate of tax for capital gain income of
the loss. The next item to be used would be deductions resulting in a current
year operating loss, and these would be valued at the marginal rate of tax on
the income they offset. This is normally 46 percent under current law, but would
be less


                                       37




for income under $100,000, which falls in to the graduated tax brackets under
Reg.1.1502-33 (d)(2), the amount of each graduated rate bracket is apportioned
equally by dividing that amount by the number of corporations that where members
of the group. Additionally, an alternative is to allocate the amount of each
graduated rate bracket based on an election made be each of the companies' and
including with that year's tax return. Operating loss carryovers would be used
next, and finally credits would be used. Credits will be valued at 100 percent,
since they result in dollar for dollar savings. Where the total amount of an
item is not used, the savings will be allocated to each member in proportion to
his share of the total of that benefit available from all members of the
consolidated group.

(4) Benefiting members will reimburse the other members prior to the filing of
the consolidated tax return.

A more complicated situation is presented when there are several loss companies.
Assume that the facts are the same as above except that there are three loss
companies: C, D, and E with the following tax savings items:

Allocation of the $25,000 benefit from Step 2 would proceed as follows:




                                                                                 Remaining

                                                      -------- -------- -------- ----------

Thus companies A and B would reimburse C, D and E for the above amounts. There
will be credit carryovers for C, D, and E of $170, $340, and $170, respectively.


Separate Return Liability

The allocations and reimbursements outlined above use the concept of a "separate
return tax liability" as a starting point for allocations. This liability is the
amount which a member of the affiliated group would pay of it filed a separate
return. It is calculated in three basic steps.

(1) The rules for consolidated return deferred accounting, inventory
adjustments, basis determination, basis adjustments, excess losses, earnings and
profits, and obligations of members must be applied.

(2) Intercompany dividends are eliminated and no dividend received or paid
deduction is allowed on intercompany dividends.

(3) Adjustments are made for specific items used in the consolidated return
which must be divided by some equitable method among the members.

The third step is the subject of this part of the Appendix. Two different
approaches may be taken for the apportionment of the limits, deductions, and
exemptions used to reach tax liability.


                                       38




It is recognized that each company is a part of an affiliated group, and that
all credits, deductions and limitations must be apportioned in some equitable
manner.

Specific Apportionments

(1) Carryovers. On a consolidated basis, items such as operating losses, capital
losses, and contributions will be used first from the current year and then
carried forward from the oldest year forward until exhausted. It is the
intention of the Tax Sharing Agreement, for allocation and reimbursement
purposes, that a member shall use its own carryovers first before it is required
to reimburse another member for use of its carryover in consolidation, without
regard for the fact that the tax regulations for consolidated returns may
require a different order.

(2) Contribution Deduction. The amount of the contribution deduction is limited
to 10% of consolidated taxable income. Thus the amount allowable may exceed the
actual contributions. In order to avoid having a consolidated contribution
carryover which is not owned by a member, each member agrees that its deduction
be limited to its proportionate share on a separate return basis of the
consolidated contribution deduction in a given year, rather than 10% of its
separate return income, and that any contribution in excess of such amount be
treated as its own carryover.

If the consolidated deduction is greater than the separate deductions of the
profitable members (thus permitting a deduction for contributions of a loss
member) the excess allowable deduction will be allocated to the loss members in
proportion to the excess allowable over their available contributions.

(3) Tax Brackets. The members agree that the brackets will first be applied
equally to the members with ordinary income. If the allocated amount exceeds
income, the excess can be reapplied equally to the other members with remaining
income.

(4) I.T.C. Limitation. The limitation on 100% utilization of investment tax
credit provided by Internal Revenue Code S46(a)(3), currently $25,000, will be
allocated equally among the members with tax liability and available credits,
with any excess to be allocated equally to those with remaining liability and
credits.


                                       39


(5) I.T.C. Limit for Used Property. The limitations on used property cost deemed
eligible for investment credit, currently $215,000, will be allocated equally
among the companies that have used property acquisitions with a ten year
recovery life in any year. If a member is unable to utilize all of its allocated
amount the excess will be allocated proportionately to the members with used
property acquisitions in excess of their allocated share. If there are
insufficient ten year recovery life assets, the remainder will be allocated to
five year recovery life assets in a similar manner. Likewise, if there are not
enough ten and five year recovery life assets, the remainder of the $100,000
limitation will be allocated equally to members having three year recovery life
used property additions.

(6) Future Developments. Any credits, deductions, or other items established by
future legislation will be allocated in a manner consistent with the above
methods.

The foregoing examples are for illustrative purposes and are not intended to
cover all possible situations that may arise.
