Any such statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this registration statement. Item 5. Interests of Named Experts and Counsel. Paul K. Connolly, a member of the firm of LeBoeuf, Lamb, Greene & MacRae, L.L.P., which is rendering an opinion on the validity of the securities being registered hereunder, owns approximately 3,257 shares of common stock as of the date of this registration statement, including shares that may be acquired within 60 days pursuant to the exercise of stock options. Mr. Connolly is a participant in our dividend reinvestment plan and, as such, acquires additional shares of our common stock at regular intervals. 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 "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 II-2
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; and (2) the director furnishes the corporation an 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 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 NHBCA. Any indemnification under Article X 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 NHBCA, such determination to be made by the Board of Directors, by majority II-3
vote of a quorum, or by other persons authorized to make such a determination under the NHBCA. The right of indemnification arising under Article X was 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 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 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 X 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 X or otherwise. As used in Article X, the term "person" includes heirs, executors, administrators or other legal representatives. As used in Article X, 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. Article X of the Company's By-Laws also allows the Company to 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 NHBCA. The obligation to indemnify and reimburse such person under the Company's 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. The Company maintains liability insurance protecting it, as well as its directors and officers, against liability by reason of their being or having been directors or officers. Item 8. Exhibits.

Item 9. Undertakings. 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 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 (1)(i) and (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. (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. II-6
(4) 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. 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.

EXHIBIT 4(e) RESTRICTED STOCK AGREEMENT This Restricted Stock Agreement (the "Agreement"), dated as of ____________, 200_, between Unitil Corporation (the "Company") and ______________, an employee of the Company (the "Employee"). WITNESSETH THAT: WHEREAS, the Company maintains the Unitil Corporation 2003 Restricted Stock Plan (the "Plan"); and WHEREAS, the Compensation Committee (the "Committee") of the Board of Directors of the Company has approved the grant of an Award of Restricted Stock to the Employee upon the terms and subject to the conditions of the Plan and this Agreement; NOW, THEREFORE, IT IS AGREED, by and between the Company and the Employee as follows: 1. Grant of Award. The Company hereby grants to the Employee an Award of ___________ shares (the "Restricted Shares") of the Company's common stock, no par value (the "Shares"), upon the terms and subject to the conditions set forth in this Agreement and the Plan. The Plan is hereby incorporated herein by reference as a part of this Agreement. 2. Representations of Employee. The Employee hereby (i) accepts the award of the Restricted Shares described in paragraph 1; (ii) agrees that the Restricted Shares will be held by him and his successors subject to (and will not be disposed of except in accordance with) all of the restrictions, terms and conditions contained in this Agreement; (iii) represents that he is acquiring the Restricted Shares for investment and not with a view to or for resale or distribution thereof; and (iv) agrees that any certificates issued for the Restricted Shares may bear the following legend or such other legend as the Company, from time to time, deems appropriate: "The transfer of the Shares represented by this certificate is restricted by the terms of a Restricted Stock Agreement dated as of __________, 200_, a copy of which is on file at the Company's principal office; no transfer of the Shares represented by this certificate shall be valid or effective until the conditions with respect to such transfer contained in the Agreement have been met."3. Vesting. 25% of the Restricted Shares shall become fully vested and nonforfeitable on each of ________, 200_, ________, 200_, ________, 200_, and ________, 200_, provided the Employee still is, and since the date of this Agreement has continuously been, employed by the Company as of such dates. 4. Restrictions. The Employee may not sell, assign, transfer, pledge or otherwise dispose of or encumber any of the Restricted Shares, or any interest therein, and the Restricted Shares shall be subject to forfeiture, until the Employee's rights in such Shares have vested in accordance with this Agreement (the period of time until the Restricted Shares have vested is referred to as the "Period of Restriction"). Any purported sale, assignment, transfer, pledge or other disposition or encumbrance in violation of this Agreement will be void and of no effect. 5. Voting and Dividends. Except as provided in this paragraph, with respect to the Restricted Shares, the Employee shall have all of 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 any Restricted Shares during the Period of Restriction shall not be contingent upon vesting of the Restricted Shares to which they relate. In the event any non-cash dividends or other distributions, whether in property, or stock of another company, are paid on any Restricted Shares during the Period of Restriction, such non-cash dividends or other distributions payable to the Employee shall be retained by the Company and not delivered to the Employee until such time as the Period of Restriction on the shares with respect to which such non-cash dividends or other distributions have been paid shall have lapsed and such shares become fully vested and not subject to forfeiture to the Company. Such non-cash dividends or distributions with respect to the Restricted Shares shall be paid to the Employee upon the lapse of the restrictions or retained by the Company in the event the Restricted Shares on which such non-cash dividends or other distributions were paid are forfeited to the Company. Any Shares issued pursuant to Section 4.2 of the Plan with respect to the Restricted Shares shall be treated as additional Restricted Shares and shall be subject to the same restrictions and other terms and conditions that apply with respect to, and shall vest or be forfeited at the same time as, the Restricted Shares with respect to which such Shares are issued. 6. Forfeiture. Upon termination of employment with the Company for any reason except death, retirement or Disability, the Employee shall forfeit all unvested Restricted Shares, and shall not receive any compensation for such forfeited Restricted Shares. The Employee shall have no further rights as a shareholder of the Company with respect to the forfeited Restricted Shares, including, without limitation, any right to receive any distribution payable to shareholders of record on or after the date of such forfeiture.
7. Certificates and Stock Power. As soon as practicable after the date of this Agreement, the Company shall issue a stock certificate in respect of the Restricted Shares which will be registered in the Employee's name, and shall bear whatever legend the Committee shall determine, including, but not limited to, the legend set forth in paragraph 2. Such certificate shall be held by the Company pending vesting of the Restricted Shares. To the extent the Restricted Shares become vested, the Company shall promptly provide the Employee (or in the case of his death, his designated beneficiary) the appropriate certificate for the vested Shares. The Employee shall execute appropriate stock powers in blank and such other documents as the Company shall prescribe. 8. Withholding and Notification of Section 83(b) Election. The Company shall have the right to deduct or withhold, or require the Employee to remit to the Company, an amount in cash (or in Shares, subject to Section 14.2 of the Plan) sufficient to cover any tax, including any Federal, state or local income or employment tax, required by to be withheld or otherwise deducted and paid with respect to such the Restricted Shares or the vesting thereof. The Employee agrees to notify the Company if he makes the election provided for in Section 83(b) of the Internal Revenue Code of 1986, as amended, with respect to the Restricted Shares. 9. No Right to Employment. Nothing in this Agreement shall confer upon the Employee any right to continue in the employ of the Company or shall interfere with or restrict in any way the rights of the Company to terminate the Employee's employment. 10. Amended. This Agreement may be amended or supplemented at any time by the mutual written consent of the parties hereto. 11. Governing Law. The laws of the State of New Hampshire shall govern the interpretation, validity and performance of the terms of this Agreement regardless of the law that might be applied under principles of conflict of laws. 12. Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the successors, assigns and heirs of the respective parties. 13. Notices. All notices and other communications required or permitted under this Agreement shall be written and shall be delivered personally or sent by registered or certified first-class mail, postage prepaid and return receipt required, addressed as follows: if to the Company, to the Company's executive offices at 6 Liberty Lane West, Hampton, NH 03842-1720, attention: General Counsel, and if to the Employee or his successor, to the address last furnished by the Employee to the Company. Each notice and communication shall be deemed to have been given when received by the Company or the Employee. 14. No Waiver. The failure of a party to insist upon strict adherence to any term of this Agreement on any occasion shall not be considered a waiver thereof or deprive that party of the right thereafter to insist upon strict adherence to that term or any other term of this Agreement.
15. Titles and Defined Terms. Titles are provided herein for convenience only and are not to serve as a basis for interpretation or construction of the Agreement. The masculine pronoun shall include the feminine and neuter and the singular shall include the plural, when the context so indicates. Unless otherwise indicated herein, terms with initial capital letters shall have the meanings given to them in the Plan. IN WITNESS WHEREOF, the parties hereto have duly executed this Agreement as of the day and year first above written.

EXHIBIT 5 LeBoeuf, Lamb, Greene & MacRae, L.L.P. A Limited Liability Partnership Including Professional Corporations 260 Franklin Street Boston, MA 02110 April 29, 2004 Unitil Corporation 6 Liberty Lane West Hampton, NH 03842-1720 Ladies and Gentlemen: We have acted as counsel to Unitil Corporation, a New Hampshire corporation (the "Company"), in connection with the filing of a Registration Statement on Form S-8 (the "Registration Statement") by the Company with the Securities and Exchange Commission pursuant to the Securities Act of 1933, as amended (the "Securities Act"), providing for the registration of 177,500 shares (the "Plan Shares") of the Company's common stock, no par value, to be issued pursuant to the Company's 2003 Restricted Stock 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, without investigation, 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.Unitil Corporation April 29, 2004 Page 2 Based upon the foregoing examination, and subject to the limitations set forth below, we are of the opinion that the Plan Shares 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 and sale of the Plan Shares; and (b) the consideration therefor provided for in the Plan has been received by the Company. This opinion is rendered under and limited to the New Hampshire Business Corporation Act (without reference to "blue sky" matters) and the federal law of the United States. We consent to the filing of this opinion as Exhibit 5 to the Registration Statement and in any amendments thereto. In giving such consent, we do not thereby concede that we are within the category of persons whose consent is required under Section 7 of the Securities Act, or the rules and regulations of the Securities and Exchange Commission thereunder. Very truly yours, /s/ LeBoeuf, Lamb, Greene & MacRae, L.L.P.
