PART II INFORMATION REQUIRED IN THE REGISTRATION STATEMENT Item 3. Incorporation of Documents by Reference. The following documents, which have heretofore been filed by Unitil Corporation (the "Company") with the Securities and Exchange Commission (the "Commission") pursuant to the Securities Exchange Act of 1934, as amended (the "1934 Act"), are hereby incorporated by reference in this Registration Statement: (a) The Company's Annual Report on Form 10-K for the fiscal year ended December 31, 1997. (b) The Company's Quarterly Report on Form 10-Q for the quarters ended March 31, 1998, June 30, 1998 and September 30, 1998.

All documents subsequently filed by the Company with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the 1934 Act, prior to the filing of a post-effective amendment that indicates that all securities offered hereby have been sold or that deregisters all securities then remaining unsold, shall be deemed to be incorporated by reference in this Registration Statement and to be a part hereof from the date of filing of such documents. Item 4. Description of Securities. Not applicable. Item 5. Interests of Named Experts and Counsel. No material interests. Item 6. Indemnification of Directors and Officers. The Company is organized under the laws of the State of New Hampshire. The New Hampshire Business Corporation Act (the "Act") provides that a corporation may indemnify an individual made a party to a proceeding because he is or was a director, officer, employee or agent of the corporation against liability incurred in the proceeding if: (1) he conducted himself in good faith; and (2) he reasonably believed (i) in the case of conduct in his official capacity with -2- the corporation, that his conduct was in its best interests; and (ii) in all other cases, that his conduct was at least not opposed to its best interests; and (3) in the case of any criminal proceeding, he had no reasonable cause to believe his conduct was unlawful. A corporation may not indemnify a director (x) in connection with a proceeding by or in the right of the corporation in which the director was adjudged liable to the corporation; or (y) in connection with any other proceeding charging improper personal benefit to him, whether or not involving action in his official capacity, in which he was adjudged liable on the basis that personal benefit was improperly received by him. Unless limited by its articles of incorporation, a corporation shall indemnify a director or officer who was wholly successful, on the merits or otherwise, in the defense of any proceeding to which he was a party because he is or was a director or officer of the corporation against reasonable expenses incurred by him in connection with the proceeding. A corporation may purchase and maintain insurance on behalf of an individual who is or was a director, officer, employee, or agent of the corporation, or who, while a director, officer, employee or agent of the corporation, is or was serving at the request of the corporation as a director, officer, partner, trustee, employee, or agent of another foreign or domestic corporation, partnership, joint venture, trust, employee benefit plan, or other enterprise, against liability asserted against or incurred by him in that capacity or arising from his status as a director, officer, employee, or agent, whether or not the corporation would have power to indemnify him against the same liability under the Act. Article X of the Company's By-Laws provides that the Company 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, 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 Company, or while serving at the request of the Company 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 Company, 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 Act. Any indemnification under this Article shall be made by the Company 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 Company 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 -3- 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 Company as directors, officers or trustees of another organization in which the Company has any direct or indirect interest as a shareholder, creditor or otherwise. The Company may purchase and maintain insurance on behalf of any person who was or is a Director, officer or employee of the Company or any of its subsidiaries, or who was or is serving at the request of the Company as a fiduciary of any employee benefit plan of the Company 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 Company 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. The Company holds a directors and officers liability and corporate indemnification policy to protect itself and its directors, officers, employees and agents against any expense, liability or loss, subject to certain limits in coverage and deductibles, whether or not the Company would have the power to indemnify such person against such expense, liability or loss under the Act.

(included in Exhibit 5). 23.2 Consent of Grant Thornton LLP. 24 Power of Attorney (included in Part II under the caption "Signatures"). Item 9. Undertakings. (a) The undersigned Registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post- effective amendment to this Registration Statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective Registration Statement. (iii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement; provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the Registration Statement is on Form S-3, Form S-8 or Form F-3, and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 and that are incorporated by reference in the Registration Statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. -5- (3) To remove from registration by means of a post-effective amendment any of the securities being registered that remain unsold at the termination of the offering. (b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the Registration Statement shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. -6- SIGNATURES The Registrant. Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the Town of Hampton, the State of New Hampshire, on this 4th day of March, 1999.

regulations relating to the Plan, to determine the terms and provisions of Stock
Option  Agreements and to make all other  determinations  necessary or advisable
for the  administration  of the Plan. Any controversy or claim arising out of or
related  to the  Plan  shall  be  determined  unilaterally  by  and in the  sole
discretion  of the  Committee.  Any  determination,  decision  or  action of the
Committee in connection with the construction,  interpretation,  administration,
implementation or maintenance of the Plan shall be final, conclusive and binding
upon all  Grantees and all  person(s)  claiming  under or through any  Grantees.
Notwithstanding  anything contained in this Section 4 to the contrary, no member
of the Committee shall have the authority to render any decision with respect to
his or her participation in or entitlement to benefits under the Plan.

     5.  Amendment or  Termination.  The Board may, at any time,  alter,  amend,
suspend,  discontinue,  or terminate the Plan; provided,  however,  that no such
action shall  adversely  affect the right of any Grantee  under any Stock Option
previously granted thereto hereunder.

     6. Effective Date of Plan. The Plan shall become  effective on December 11,
1998.

II.  GRANTS AND EXERCISE OF STOCK OPTIONS

     1. Granting of Stock Options.

          a. The Committee shall determine and shall designate from time to time
     those Employees and Directors who are to be granted Stock Options and shall
     specify  the  number of  shares  of Stock  subject  to each  Stock  Option;
     provided,  however,  that  Stock  Options  for  not  more  than  5% of  the
     outstanding  Stock  may be issued  in any one year to  officers,  Directors
     and/or key employees of the Corporation.

          b.  The  Committee  may  grant at any time  new  Stock  Options  to an
     Employee or a Director who has previously  received Stock Options,  whether
     such prior  Stock  Options  are still  outstanding,  have  previously  been
     exercised  in  whole  or in part or are  canceled  in  connection  with the
     issuance of new Stock Options.

          c. When granting a Stock Option,  the  Committee  shall  determine the
     purchase  price of the Stock subject  thereto and specify such price in the
     applicable Stock Option Agreement.

          d. The Committee, in its sole discretion,  shall determine whether any
     particular Stock Option shall become


                                       -4-







     exercisable in one or more installments, specify the installment dates and,
     within the limitations  herein provided,  determine the total period during
     which the Stock Option is exercisable. Further, the Committee may make such
     other  provisions  as may appear  generally  acceptable or desirable to the
     Committee.

     2.  Exercise of Stock  Options.  The purchase  price of Stock  subject to a
Stock Option  shall be payable upon  exercise of the Option in cash or by check,
bank  draft or postal  or  express  money  order,  or  pursuant  to a  "cashless
exercise"  utilizing a brokerage  firm. The Committee,  in its  discretion,  may
permit a Grantee to make partial or full  payment of the  purchase  price by the
surrender of Stock owned by the Grantee prior to the date of exercise. Shares of
Stock  surrendered  in payment of the purchase  price as provided above shall be
valued at the Fair Market Value  thereof on the date of  exercise.  Surrender of
such Stock shall be  evidenced by delivery of the  certificates(s)  representing
such shares in such manner,  and endorsed in such form, or  accompanied by stock
powers endorsed in such form, as the Committee may determine or by attestation.

     3.  Termination  of  Employment  or  Director  Status.  Except as  provided
otherwise in the applicable Stock Option Agreement (in which case the provisions
of the Stock Option  Agreement shall control over the provisions of this Section
3):

          a.  Except as  provided in  paragraphs  b and c below,  if a Grantee's
     employment or status as a Director with the  Corporation or an Affiliate is
     terminated voluntarily by the Grantee or by the Corporation or an Affiliate
     other than for Cause,  only those Stock  Options held by the Grantee  which
     were immediately exercisable at the termination of the Grantee's employment
     or status as a Director shall be  exercisable by the Grantee  following the
     termination of the Grantee's employment or status as a Director. Such Stock
     Options  must be  exercised  within  3 months  after  such  termination  of
     employment or status as a Director (but in no event after expiration of the
     Option Period) or they shall be forfeited.

          b.  Notwithstanding  anything to the contrary contained in paragraph a
     above,  if a Grantee's  employment  with the Corporation or an Affiliate or
     status as a Director is terminated by the  Corporation  or an Affiliate for
     Cause, all then outstanding  Stock Options held by the Grantee shall expire
     immediately  and such  Stock  Options  shall not be  exercisable  after the
     termination of the Grantee's employment or status as a Director.

          c. Notwithstanding  anything to the contrary contained in paragraphs a
     and b above, if a Grantee's employment with the Corporation or an Affiliate
     or status as a Director is terminated on account of the Grantee's death or,


                                       -5-







     if the Grantee is an Employee, on account of the Grantee's Disability, only
     those Stock Options held by the Grantee which were immediately  exercisable
     at the date of the Grantee's  death or Disability  shall be  exercisable by
     the Grantee,  the Grantee's  guardian or legal  representative,  or, if the
     Grantee is not then living,  by the  representative of the Grantee's estate
     or beneficiaries  thereof to whom the Stock Options have been  transferred.
     Such Stock  Options  must be exercised by the earlier of (i) 12 months from
     the date of the Grantee's  death or  Disability,  or (ii) the expiration of
     the Option Period, or they shall be forfeited.

III. GENERAL PROVISIONS

     1. Recapitalization Adjustments.

          a. In the event of any change in  capitalization  affecting the Stock,
     including,  without  limitation,  a stock  dividend or other  distribution,
     stock  split,   reverse  stock  split,   recapitalization,   consolidation,
     subdivision,  split-up,  spin-off,  split-off,  combination  or exchange of
     shares or other form of  reorganization or  recapitalization,  or any other
     change  affecting the Stock,  the Committee  shall  authorize and make such
     proportionate adjustments,  if any, as the Committee shall deem appropriate
     to reflect such change, including,  without limitation, with respect to the
     aggregate  number of shares of Stock for which  Stock  Options  in  respect
     thereof  may be  granted  under  the  Plan,  the  number of shares of Stock
     covered by each outstanding Stock Option,  and the purchase price per share
     of Stock in respect of outstanding Stock Options.

          b. Any provision hereof to the contrary notwithstanding,  in the event
     the Corporation is a party to a merger or other reorganization, outstanding
     Stock   Options   shall  be   subject  to  the   agreement   of  merger  or
     reorganization.  Such agreement may provide,  without  limitation,  for the
     assumption of outstanding Stock Options by the surviving corporation or its
     parent,  for their continuation by the Corporation (if the Corporation is a
     surviving  corporation) for accelerated vesting and accelerated  expiration
     or for settlement in cash.

     2. General.

          a. Each Stock Option shall be evidenced by a Stock Option Agreement.

          b. The  granting  of a Stock  Option  in any year  shall  not give the
     Grantee  any right to  similar  grants  in future  years or any right to be
     retained as an Employee or as a Director,  and all  Grantees  shall  remain
     subject to discharge


                                       -6-







     or removal to the same extent as if the Plan were not in effect.

          c. No Grantee,  and no beneficiary  or other person  claiming under or
     through  him or her,  shall have any right,  title or interest by reason of
     any Stock Option to any particular assets of the Corporation, or any shares
     of Stock  allocated  or reserved for the purposes of the Plan or subject to
     any Stock Option except as set forth herein.

          d. No Stock Option shall or may be sold, exchanged, assigned, pledged,
     encumbered,  or otherwise hypothecated or disposed of except (i) by will or
     the  laws of  descent  and  distribution,  or  (ii)  subject  to  Committee
     approval,  by gift to any member of the Grantee's  immediate  family,  to a
     trust  for  the  benefit  of  such  an  immediate  family  member  or  to a
     partnership in which such immediate family members are the sole partners. A
     Stock Option may be exercisable  during the Grantee's  lifetime only by the
     Grantee or by the Grantee's guardian or legal representative  unless it has
     been transferred by gift to a member of the Grantee's  immediate family, to
     a  trust  for  the  benefit  of such an  immediate  family  member  or to a
     partnership  described in the immediately preceding sentence, in which case
     it shall be  exercisable  solely by such  transferee.  For purposes of this
     paragraph  d, a  Grantee's  "immediate  family"  shall  mean the  Grantee's
     spouse, children and grandchildren.  Notwithstanding any such transfer, the
     Grantee  will  continue  to  be  subject  to  the  income  tax  withholding
     requirements of paragraph f of this Section 2.

          e.  Notwithstanding any other provision of the Plan or agreements made
     pursuant  hereto,  the  Corporation's  obligation  to issue or deliver  any
     certificate or certificates  for shares of Stock under a Stock Option,  and
     the transferability of Stock acquired by exercise of a Stock Option,  shall
     be subject to all of the following conditions:

               (i) Any registration or other  qualification of such shares under
          any state or federal law or regulation,  or the  maintaining in effect
          of any such  registration or other  qualification  which the Committee
          shall,  in its absolute  discretion  upon the advice of counsel,  deem
          necessary or advisable;

               (ii) The obtaining of any other consent, approval, or permit from
          any state or federal governmental agency which the Committee shall, in
          its absolute  discretion  upon the advice of counsel,  determine to be
          necessary or advisable; and

               (iii) Each stock  certificate  issued  pursuant to a Stock Option
          shall bear such legends which the


                                       -7-






          Committee shall determine,  in its absolute discretion,  are necessary
          or  advisable,  or which in the opinion of counsel to the  Corporation
          are required under applicable federal or state securities laws.

               f. All  payments to  Grantees  or to their legal  representatives
          shall be subject to any applicable tax, community  property,  or other
          statutes or  regulations  of the United  States or of any state having
          jurisdiction  thereof.  The  Grantee  may  be  required  to pay to the
          Corporation or an Affiliate the amount of any withholding  taxes which
          the Committee, in its sole discretion,  deems necessary to be withheld
          in order to comply with any applicable  statutes or  regulations  with
          respect  to a Stock  Option or its  exercise.  In the event  that such
          payment is not made when due, the  Corporation or Affiliate shall have
          the right to deduct,  to the extent permitted by law, from any payment
          or settlement of any kind  otherwise due to such person all or part of
          the amount  required  to be  withheld.  The  Grantee  may use Stock to
          satisfy the Grantee's  income tax  obligation  with respect to a Stock
          Option or its exercise. If Stock is to be used to satisfy any such tax
          withholding,  such Stock  shall be valued  based upon the Fair  Market
          Value of such Stock as of the date the tax  withholding is required to
          be made, such date to be determined by the Committee.  The Corporation
          shall not be  required  to issue  Stock  until  such  obligations  are
          satisfied.

               g. A Grantee  entitled to Stock as a result of the exercise of an
          Option shall not be deemed for any purpose to be, or have rights as, a
          shareholder of the  Corporation by virtue of such exercise,  except to
          the extent a Stock  certificate is issued  therefor and then only from
          the date such certificate is issued.  No adjustments shall be made for
          dividends or  distributions  or other rights for which the record date
          is prior to the date  such  Stock  certificate  is  issued,  except as
          otherwise  provided  herein.  The  Corporation  shall  issue any Stock
          certificates  required to be issued in connection with the exercise of
          a Stock Option with reasonable promptness after such exercise.

               h. The Plan and the grant or  exercise of Stock  Options  granted
          under the Plan shall be subject to, and shall in all  respects  comply
          with, applicable New Hampshire law.

               i. Upon the  occurrence of a Change of Control,  all  outstanding
          Stock  Options  shall  automatically  become  100%  vested  and  fully
          exercisable.

not less than one-tenth (1/10) of the capital stock of the Corporation  entitled
to vote at such  meeting,  shall so request  the  Secretary  in  writing,  which
writing shall indicate the purposes for which said meeting is to be called.

less than ten (10) nor more than  fifty  (50) days  before the day named for the
meeting.  Notices of all meetings of  stockholders  shall state the purposes for
which the meetings are called.

     In the event of the annual  meeting,  by mistake  or  otherwise,  not being
called and held as herein provided, a special meeting of the stockholders may be
called and held in lieu of and for the purposes of the annual meeting.  Any such
special meeting may be called in the same manner as other special meetings or as

                       ARTICLE II * * * BOARD OF DIRECTORS

     The property, business and affairs of the Corporation shall be managed by a
Board of Directors,  and they are hereby vested in such  management with all the

three (3) years, or in the event that a Director is being elected to a class the

qualified.

     Any vacancy occurring in the Board,  whether due to the death,  resignation
or other  inability to serve of any Director  previously  elected,  or due to an
increase in the number of Directors  comprising the Board,  may be filled by the
affirmative  vote of a majority of the remaining  Directors,  though less than a
quorum of the Board.  A Director  elected to fill a vacancy shall be elected for
the unexpired term of his predecessor in office. In the event that the number of
Directors  comprising  the Board is  increased  by the  Board and  directorships
created thereby filled by the Board,  then the Directors so elected by the Board
shall be  assigned  by the Board to each class in such manner so that the number
of Directors comprising each class is as nearly equal as possible, and each such
Director elected by the Board shall serve until the next meeting of shareholders
at  which  Directors  are  elect ed and  until  his  successor  is  elected  and
qualified.

the  President or any two  Directors  shall call any such  meeting,  twenty-five
hours notice thereof being given.  Any such meeting,  however,  and all business
transacted  thereat,  shall be legal and valid without notice if all the members
of the Board are present in person or participating  therein,  or if the members
who are  absent  waive  notice by a signed  written i  nstrument  filed with the
records of the meeting or assent in writing to the action taken or to be taken.

     A majority  of the Board of  Directors  shall  constitute  a quorum for the
transaction  of business,  but a lesser number may adjourn any meeting from time
to time, and the meeting may be held as adjourned without further notice. When a
quorum is present at or participating in any meeting,  a majority of the members
in attendance thereat or participating therein shall decide any question brought
before such  meeting,  unless  otherwise  required by statute,  the  Articles of
Incorporation or these By-Laws.

     Members of the Board of  Directors  shall be  entitled  to such  reasonable
compensation for their services as Directors as shall be fixed from time to time
by vote of the Board of  Directors  and shall also be entitled to  reimbursement
for any reasonable  expenses  incurred in connection with attendance at meetings
thereof.  The  compensation  of  Directors  may be on such  basis  as  shall  be
determined in the vote of the Board relating thereto.

establishing  it,  and all  members  of each  committee  shall  be  entitled  to

                      ARTICLE IX * * * ASSISTANT TREASURERS

     In case of the death,  absence or  inability to act of the  Treasurer,  any
Assistant  Treasurer  may  exercise  any or all of the powers of the  Treasurer,
subject,  however,  to the  limitation  expressed in Article VII hereof and such
further limitations as the Board of Directors may impose.


                         ARTICLE X * * * INDEMNIFICATION

     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, 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  reasonable  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.


                     ARTICLE XI * * * CERTIFICATES OF STOCK

     Each stockholder shall be entitled to a certificate  representing shares of
the capital  stock of the  Corporation  owned by him, in such form as shall,  in
conformity  to law, be  prescribed  from time to time by the Board of Directors.
Certificates  of stock shall be signed by the  Chairman or Vice  Chairman of the
Board  of  Directors  or by the  President  or  any  Vice  President  and by the
Secretary or any Assistant  Secretary or the Treasurer or an Assistant Treasurer
of the Corporation and may be sealed with the corporate seal. Such seal may be a
facsimile,  engraved or printed. When any such certificate is manually signed by
a transfer  agent  and/or a registrar,  the  signatures  of the duly  authorized
officers of the Corporation upon such certificate may be facsimiles, engraved or
printed.  In case any officer who has signed or whose  facsimile  signature  has
been  placed  upon any  certificate  shall  have  ceased to be such  before  the
certificate is issued,  it may be issued by the Corporation with the same effect
as if such officer had not ceased to be such at the time of its issue.

     Shares of stock of the  Corporation  may be transferred on the books of the
Corporation by the registered  owner thereof or by his duly authorized  attorney
by assignment thereof in writing, accompanied by delivery of the certificate. No
such transfer of stock,  however,  shall affect the right of the  Corporation to
pay any dividend  thereon or to treat the holder of record as the holder in fact
until the transfer has been recorded upon the books of the  Corporation or a new
certificate  has  been  issued  to  the  person  to  whom  the  stock  has  been
transferred.

     In case of the loss of a  certificate,  a duplicate may be issued upon such
reasonable terms as the Board of Directors shall prescribe.

     The  Board  of  Directors  may  appoint  one or more  transfer  agents  and
registrars  and  may  require  all  certificated   representing  shares  of  the
Corporation's stock to bear the signature or signatures of any of them.


                   ARTICLE XII * * * CLOSING OF TRANSFER BOOKS

     The  transfer  books of the  Corporation  may be closed  for not  exceeding
fifteen  (15) days next prior to any  meeting of the  stockholders,  and at such
other times and for such reasonable periods as may be determined by the Board of
Directors.  However,  in the event  dividends are declared,  the stock  transfer
books of the  Corporation  will not be closed but record  dates will be fixed by
the Board of Directors,  upon which the Corporation's transfer agent will take a
record  of all  stockholders  entitled  to the  dividends  so  declared  without
actually closing the books for transfers of stock of the Corporation.


                         ARTICLE XIII * * * FISCAL YEAR

     The fiscal year of the Corporation shall end on the 31st day of December in
each year.


                          ARTICLE XIV * * * AMENDMENTS

     These  By-Laws  may,  upon notice,  be altered,  amended or repealed at any
meeting of the  stockholders by vote of the holders of a majority or more of the
stock  entitled  to vote at such  meeting.  Notwithstanding  the  foregoing,  as
provided by statute,  a majority of the Board of  Directors  may make,  amend or
repeal these  By-Laws in whole or in part,  except with respect to any provision
thereof which by statute or by the Articles of Incorporation  requires action by
the stockholders.

Unitil Corporation
6 Liberty Lane West
Hampton, NH 03842

Ladies and Gentlemen:

     We have acted as counsel to Unitil Corporation, a New Hampshire corporation
(the "Company"),  in connection with its Registration Statement on Form S-8 (the
"Registration  Statement")  executed  and filed for the  purpose of  registering
under the Securities Act of 1933, as amended (the "1933 Act"), 350,000 shares of
the Company's  Common  Stock,  no par value (the "Common  Stock"),  to be issued
pursuant to the Company's 1998 Stock Option Plan (the "Plan").

     In  connection  with this opinion,  we have  examined  originals or copies,
certified or otherwise  identified  to our  satisfaction,  of such  instruments,
certificates, records and documents, and have reviewed such questions of law, as
we have deemed  necessary or appropriate  for purposes of this opinion.  In such
examination, we have assumed the genuineness of all signatures, the authenticity
of all documents  submitted to us as originals,  the  conformity to the original
documents of all documents submitted to us as copies and the authenticity of the
originals  of all  such  latter  documents.  As to any  facts  material  to this
opinion, we have relied upon the aforesaid  instruments,  certificates,  records
and documents and inquiries of Company representatives.

     Based upon the foregoing  examination,  and subject to the  limitations set
forth  below,  we are of the opinion that the Common  Stock,  when issued by the
Company upon exercise of the stock options pursuant to the Plan, will be validly
issued, fully paid and nonassessable when:

     (a) the  Registration  Statement  shall have become,  and for so long as it
shall remain, effective for the purpose of the issuance of the Common Stock; and

     (b) the  consideration  therefor provided for in the Plan has been received
by the Company.
