  of Directors and Officers </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">We are organized under the laws of the State of New Hampshire. The New Hampshire Business Corporation Act (the
  &#147;NHBCA&#148;) provides that a corporation may indemnify an individual made a party to a proceeding because he is or was a director against liability incurred in the proceeding if: (1)&nbsp;he conducted himself in good faith; and (2)&nbsp;he
  reasonably believed (i)&nbsp;in the case of conduct in his official capacity with the corporation, that his conduct was in its best interests; and (ii)&nbsp;in all other cases, that his conduct was at least not opposed to its best interests; and
  (3)&nbsp;in the case of any criminal proceeding, he had no reasonable cause to believe his conduct was unlawful. A corporation may pay for or reimburse the reasonable expenses incurred by a director who is a party to a proceeding in advance of the
  final disposition of the proceeding if (1)&nbsp;the director furnishes the corporation a written affirmation of his good faith belief that he has met the standard of conduct described in the preceding sentence, (2)&nbsp;the director furnishes the
  corporation a written undertaking, executed personally or on his behalf, to repay the advance if it is ultimately determined that he did not meet the standard of conduct and (3)&nbsp;a determination is made that the facts then known to those making
  the determination would not preclude indemnification. Unless a corporation&#146;s Articles of Incorporation provide otherwise, the corporation may indemnify and advance expenses to an officer, employee or agent of the corporation who is not a
  director to the same extent as to a director. A corporation may not indemnify a director (x)&nbsp;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)&nbsp;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 NHBCA. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Article XIII of our Fourth Amended and Restated
  <FONT STYLE="white-space:nowrap">By-Laws</FONT> provides that we 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&#146;s having served as, or by reason of the person&#146;s alleged acts or omissions while serving as, a director, officer, employee or agent of Unitil Corporation, or while serving at our
  request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses, including attorneys&#146; fees, judgments, fines and amounts paid in settlement or otherwise actually
  and reasonably incurred by such person 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 Unitil 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 NHBCA. Any indemnification under Article XIII shall be made by us 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 NHBCA, 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 NHBCA. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The right
  of indemnification arising under Article XIII of our Fourth Amended and Restated <FONT STYLE="white-space:nowrap">By-Laws</FONT> was adopted for the purpose of inducing persons to serve and to continue to serve Unitil Corporation without concern

  Article XIII are separable, and, if any provision or portion thereof is for any reason held inapplicable, illegal or ineffective, such holding will not affect any other right of indemnification existing under Article XIII or otherwise. As used in

  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. </P>

  Item 5. Interests of Named Experts and Counsel
  The validity of the shares of common stock to be sold under this registration statement will be passed upon for us by Patrick Taylor, our Chief Regulatory
  Counsel. As of January 20, 2025, Mr. Taylor beneficially owned approximately 2,980 shares of our common stock.
  Item 6. Indemnification
  of Directors and Officers
  We are organized under the laws of the State of New Hampshire. The New Hampshire Business Corporation Act (the
  "NHBCA") provides that a corporation may indemnify an individual made a party to a proceeding because he is or was a director 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 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 pay for or reimburse the reasonable expenses incurred by a director who is a party to a proceeding in advance of the
  final disposition of the proceeding if (1) the director furnishes the corporation a written affirmation of his good faith belief that he has met the standard of conduct described in the preceding sentence, (2) the director furnishes the
  corporation a written undertaking, executed personally or on his behalf, to repay the advance if it is ultimately determined that he did not meet the standard of conduct and (3) a determination is made that the facts then known to those making
  the determination would not preclude indemnification. Unless a corporation's Articles of Incorporation provide otherwise, the corporation may indemnify and advance expenses to an officer, employee or agent of the corporation who is not a
  director to the same extent as to a director. 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 NHBCA.
  Article XIII of our Fourth Amended and Restated
  By-Laws
  provides that we 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 Unitil Corporation, or while serving at our
  request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses, including attorneys' fees, judgments, fines and amounts paid in settlement or otherwise actually
  and reasonably incurred by such person 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 Unitil 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 NHBCA. Any indemnification under Article XIII shall be made by us 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 NHBCA, 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 NHBCA.
  The right
  of indemnification arising under Article XIII of our Fourth Amended and Restated
  By-Laws
  was adopted for the purpose of inducing persons to serve and to continue to serve Unitil Corporation without concern
  that their service may expose them to personal financial harm. It is to be broadly construed, applied and implemented in light of that purpose. It is not to 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 is it to be
  2
  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
  Article XIII are separable, and, if any provision or portion thereof is for any reason held inapplicable, illegal or ineffective, such holding will not affect any other right of indemnification existing under Article XIII or otherwise. As used in
  Article XIII, the term "person" includes heirs, executors, administrators or other legal representatives. As used in Article XIII, 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 our request as directors, officers or trustees of another organization in which we have any direct or indirect
  interest as a shareholder, creditor or otherwise.
  Article XIII of our Fourth Amended and Restated
  By-Laws
  also
  allows us to purchase and maintain insurance on behalf of any person who was or is a director, officer or employee of Unitil Corporation or any of its subsidiaries, or who was or is serving at our request as a fiduciary of any employee benefit plan
  of Unitil 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 we would have the power to indemnify such person
  against such liability under the provisions of the NHBCA. The obligation to indemnify and reimburse such person under our Fourth Amended and Restated
  By-Laws,
  if applicable, will be reduced by the amount of
  any such insurance proceeds paid to such person, or the representatives or successors of such person.

  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 a 20% 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-8
  and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Securities and
  Exchange Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement.
  10
  (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.
  (3) To remove from registration by means of a post-effective amendment any of the securities being registered which 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 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.
  (h)
  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.
  11
  SIGNATURES AND POWER OF ATTORNEY
  Pursuant to the requirements of the Securities Act of 1933, as amended, 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, State of New
  Hampshire, on this 21
  st
  day of January, 2025.
