Philadelphia, PA 19103

Ladies and Gentlemen:

          Pennichuck Corporation, a New Hampshire corporation (the “Company”), proposes, subject to the terms and conditions stated herein, to sell to the Janney Montgomery Scott LLC (the “Underwriter”) an aggregate of 350,000 shares of the Company’s Common Stock, $1.00 par value per share (“Common Stock”). The Common Stock to be sold to the Underwriter by the Company is referred to herein as the “Firm Shares.” The Firm Shares shall be offered to the public at a public offering price of $21.00 per Firm Share (the “Offering Price”).

          In order to cover over-allotments in the sale of the Firm Shares, the Underwriter may, at the Underwriter’s election and subject to the terms and conditions stated herein, purchase for the Underwriter’s own accounts up to 52,500 additional shares of Common Stock from the Company. Such 52,500 additional shares of Common Stock are referred to herein as the “Optional Shares.” If any Optional Shares are purchased, the Optional Shares shall be purchased for offering to the public at the Offering Price and in accordance with the terms and conditions set forth herein. The Firm Shares and the Optional Shares are referred to collectively herein as the “Shares.”

          In consideration of the mutual agreements contained herein, the Company and the Underwriter, intending to be legally bound, hereby confirm their agreement as follows:

     1. Representations and Warranties of the Company. The Company represents and warrants to, and agrees with, the Underwriter that:

          (a) The Company has prepared, in accordance with the requirements of the Securities Act of 1933, as amended (the “Act”), and the rules and regulations (the “Regulations”) of the Securities and Exchange Commission (the “SEC”) thereunder and has filed with the SEC a registration statement on Form S-3 (File No. 333-160198) and one or more amendments thereto and a prospectus for the purpose of registering the Shares under the Act. The term “Registration Statement” as used herein means the registration statement (including all exhibits and information incorporated by reference therein) as amended to the date of this Agreement, and includes information (if any) contained in a form of prospectus or prospectus supplement that is deemed retroactively to be part of the Registration Statement, pursuant to Rule 430B under the Act, to be part of the registration statement as of the time specified in Rule 430B. If it is contemplated, at the time this Agreement is executed, that a post-effective amendment to the Registration Statement will be filed and must be declared effective before the offering of the Shares may commence, the term “Registration Statement” as used herein shall mean the Registration Statement as amended by such post-effective amendment. If the Company has filed, or files on or after the date of this Agreement, a registration statement to register Common Shares pursuant to Rule 462(b) under the Act (the “Rule 462(b) Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462(b) Registration Statement. The term “Base Prospectus” shall mean the base prospectus filed as part of the Registration Statement in the form in which it has most recently been filed with the SEC on or prior to the date of this Agreement. The term “Preliminary Prospectus” shall mean any preliminary prospectus supplement relating to the Shares, together with the Base Prospectus, and filed with the SEC pursuant to Rule 424(a) of the Regulations. The term “Statutory Prospectus” shall mean the Preliminary Prospectus, as amended or supplemented, immediately prior to the Initial Sale Time (as defined below), including any document incorporated by reference therein. The term “Prospectus” shall mean the final prospectus supplement relating to the Shares, together with the Base Prospectus, that is first filed pursuant to Rule 424(b) after the effective time of the Registration Statement (the “Effective Time”). The term “Issuer Free Writing Prospectus” shall have the meaning ascribed to it in Rule 433 of the Regulations relating to the Shares, in the form filed or required to be filed with the SEC or, if not required to be filed, in the form retained in the Company’s records pursuant to Rule 433(g) of the Regulations. The term “Disclosure Package” shall mean (i) the Statutory Prospectus, (ii) the Issuer Free Writing Prospectus, if any, identified in Schedule II hereto, and (iii) any other free writing prospectus defined in Rule 405 of the Regulations that is required to be filed by the Company with the SEC or retained by the Company under Rule 433 of the Regulations and that all parties hereto expressly agree to treat as part of the Disclosure Package (the “Other Free Writing Prospectus”). For purposes of this Agreement, the “Initial Sale Time” shall mean 5:00 p.m. (Eastern Time) on the date of this Agreement. All references in this Agreement to the Registration Statement, the Rule 462(b) Registration Statement, the Base Prospectus, a Preliminary Prospectus, the Statutory Prospectus, the Prospectus, the Issuer Free Writing Prospectus, the Other Free Writing Prospectus or any amendments or supplements to any of the foregoing, shall include any copy thereof filed with the SEC pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“EDGAR”).

          (b) The Registration Statement has become effective under the Act, and the SEC has not issued any stop order suspending the effectiveness of the Registration Statement or preventing or suspending the use of the Statutory Prospectus or the Prospectus, nor has the SEC instituted or, to the Company’s knowledge, threatened to institute proceedings with respect to such an order. No stop order suspending the sale of the Shares in any jurisdiction in which the Underwriter may offer the Shares has been issued, and no proceedings for that purpose have been instituted or, to the Company’s knowledge, threatened. The Company has complied in all material respects with all requests of the SEC, or requests of which the Company has been advised of any state or foreign securities commission in a state or foreign jurisdiction in which the Underwriter may offer the Shares, for additional information to be included in the Registration Statement, the Disclosure Package, or the Prospectus.

          (c) (i) The Registration Statement complied at the Effective Time and, as amended or supplemented, complies on the date hereof and will comply on the Closing Date and any Option Closing Date, in all material respects, with the requirements of the Act and the Regulations, (ii) the Registration Statement, at the Effective Time, did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (iii) the Disclosure Package, at the time it was filed and as of the Initial Sale Time, complied in all material respects with the requirements of the Act and the Regulations, (iv) the Disclosure Package at the time it was filed and as of the Initial Sale Time, did not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, (v) the Prospectus, at the time it is filed and, as amended or supplemented, as of the Closing Date and any Option Closing Date, will comply in all material respects with the requirements of the Act and the Regulations, (vi) the Prospectus, as so amended or supplemented, will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however that the representations and warranties set forth in this section do not apply to omissions from or statements in the Registration Statement, the Disclosure Package or the Prospectus based upon and in conformity with written information furnished to the Company by the Underwriter specifically for use therein, it being understood and agreed that the only information furnished by any Underwriter for use in the Registration Statement, the Disclosure Package and the Prospectus is the information as described in Section 11 of this Agreement, and (vii) the statistical and market-related data included or incorporated by reference in the Registration Statement, the Disclosure Package and the Prospectus are based on or derived from sources that the Company believes to be reliable and accurate.

          (d) As of the Initial Sale Time, the Disclosure Package complied in all material respects with the Act and the Regulations and, if filed by electronic transmission pursuant to EDGAR (except as may be permitted by Regulation S-T under the Act), was identical to the copy thereof delivered to the Underwriter for use in connection with the offer and sale of the Shares. The Disclosure Package, at the Initial Sale Time, did not, and at the Closing Date will not, contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to omissions from or statements in the Disclosure Package based upon and in conformity

with written information furnished to the Company by the Underwriter specifically for use therein, it being understood and agreed that the only such information furnished by the Underwriter for use in the Disclosure Package is the information as described Section 11 of this Agreement.

          (e) The Company (including its agents and representatives, other than the Underwriter in their capacity as such) has not used, authorized, approved or referred to and will not use, authorize, approve or refer to any Issuer Free Writing Prospectus, other than the documents listed on Schedule II hereto. Each such Issuer Free Writing Prospectus complied when issued in all material respects with the Act and the Regulations and has been filed in accordance with the Act and the Regulations (to the extent required thereby). Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Shares or until any earlier date of which the Company notified or notifies the Underwriter as described in the next sentence, did not, does not and will not include any information that, in any material respect, conflicted, conflicts or will conflict with the information contained in the Registration Statement. If at any time following issuance of an Issuer Free Writing Prospectus, there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information then contained in the Registration Statement or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, (i) the Company has promptly notified or will promptly notify the Underwriter and (ii) the Company has promptly amended or will promptly amend or supplement such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission. The foregoing sentences do not apply to conflicts with, omissions from or statements in any Issuer Free Writing Prospectus based upon and in conformity with written information furnished to the Company by any Underwriter specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter for use in any Issuer Free Writing Prospectus is the information as set forth in Section 11 of this Agreement.

          (f) The Company has not distributed and will not distribute, prior to the later of the last Option Closing Date (as defined below) and the completion of the Underwriter’s distribution of the Shares, any offering material in connection with the offering and sale of the Shares other than the Registration Statement, the Disclosure Package or the Prospectus.

          (g) The documents incorporated by reference into the Prospectus pursuant to Item 12 of Form S-3 under the Act, at the time they were filed with the SEC, complied in all material respects with the requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and with the rules and regulations promulgated under or pursuant to the Exchange Act and did not contain any untrue statement of material fact or omit to state a material fact required to be stated therein, or necessary to make the statements therein not misleading.

          (h) There are no legal or governmental proceedings pending or, to the knowledge of the Company, threatened to which the Company or any of its Subsidiaries is a party or to which any of the properties of the Company or any Subsidiary are subject that are required to be described in the Registration Statement, the Disclosure Package or the Prospectus

and are not so described or any statutes, regulations, contracts or other documents that are required to be described in the Registration Statement, the Disclosure Package or the Prospectus or to be filed as exhibits to the Registration Statement that are not described or filed as required.

          (i) The Company is a corporation duly organized, validly existing and in good standing under the laws of the State of New Hampshire, and has all necessary power and authority, to own or lease and operate its properties and to conduct its current business as described in the Registration Statement, the Disclosure Package and the Prospectus, and to execute, deliver and perform this Agreement. Pennichuck Water Works, Inc., Pennichuck East Utility, Inc., the Pittsfield Aqueduct Company, Inc., Pennichuck Water Service Corporation and The Southwood Corporation, collectively, shall herein be referred to as the “Subsidiaries”. Each Subsidiary has been duly incorporated or formed and is an existing corporation in good standing under the laws of the jurisdiction of its incorporation or formation, with all necessary power and authority, corporate and otherwise, and all required licenses, permits, certifications, registrations, approvals, consents and franchises to own or lease and operate its properties and to conduct its current business as described in the Registration Statement, the Disclosure Package and the Prospectus. The Company and its Subsidiaries are duly qualified to do business as foreign entities, and are in good standing, in all jurisdictions in which such qualification is required, except where the failure to so qualify would not have a material adverse effect on the general affairs, properties, assets, operations, condition (financial or otherwise), results of operations, stockholders’ equity, business or prospects of the business (collectively, the “Business Conditions”) of the Company and the Subsidiaries taken as a whole (a “Material Adverse Effect”). References to “material” or “materiality” or “material adverse change” as applicable to the Company or any of its Subsidiaries shall mean material to the Business Conditions of the Company and the Subsidiaries taken as a whole.

          (j) All of the outstanding shares of capital stock of each of the Subsidiaries have been duly authorized and validly issued, are fully paid and non-assessable and are owned, directly or indirectly, by the Company, free and clear of all liens, encumbrances and security interests; and no options, warrants or other rights to purchase, agreements or other obligations to issue, or other rights to convert any obligations into shares of capital stock or ownership interests in each of the Subsidiaries or securities convertible into or exchangeable for capital stock of, or other ownership interests in any of the Subsidiaries are outstanding except as disclosed in the Registration Statement, the Disclosure Package or the Prospectus. Except for shares in the Subsidiaries or except as described in the Registration Statement, the Disclosure Package or the Prospectus, neither the Company nor the Subsidiaries owns any stock or other interest whatsoever, whether equity or debt, in any corporation, limited liability company, partnership or other entity.

          (k) This Agreement has been duly authorized, executed and delivered by the Company and constitutes its legal, valid and binding obligation, enforceable against the Company in accordance with its terms, except as enforcement may be limited by bankruptcy, insolvency or other similar laws relating to or affecting the enforcement of creditors’ rights generally and subject to applicability of general principles of equity and except, as to this Agreement, as rights to indemnity and contribution may be limited by federal and state securities laws or principles of public policy.

          (l) The execution, delivery and performance of this Agreement and the transactions contemplated herein, do not and will not, with or without the giving of notice or the lapse of time, or both, (i) conflict with any term or provision of the Company’s or the Subsidiaries’ respective Certificate or Articles of Incorporation, as the case may be, or Bylaws; (ii) result in a breach of, constitute a default under, result in the termination or modification of, result in the creation or imposition of any lien, security interest, charge or encumbrance upon any of the properties of the Company or the Subsidiaries or require any payment by the Company or any of the Subsidiaries or impose any liability on the Company or any of the Subsidiaries pursuant to, any contract, indenture, mortgage, deed of trust, commitment or other agreement or instrument to which the Company or any of the Subsidiaries is a party or by which any of their respective properties are bound or affected other than this Agreement; (iii) assuming compliance with Blue Sky laws and the rules of the Financial Industry Regulatory Authority (“FINRA”) applicable to the offer and sale of the Shares, violate any law, rule, regulation, judgment, order or decree of any government or governmental agency, instrumentality or court, domestic or foreign, having jurisdiction over the Company or the Subsidiaries or any of their respective properties or businesses; or (iv) result in a breach, termination or lapse of the Company’s or the Subsidiaries’ corporate power and authority to own or lease and operate their respective properties and conduct their respective businesses, except, in the cases of clauses (ii), (iii) and (iv) above, as would not have a Material Adverse Effect.

          (m) At the date or dates indicated in the Registration Statement, the Disclosure Package or the Prospectus, the Company had or will have the capitalization set forth in the Registration Statement, the Disclosure Package and the Prospectus under the caption “Capitalization” and will have, as of the issuance of the Firm Shares on the Closing Date, the as-adjusted capitalization set forth therein as of the date indicated in the Registration Statement, the Disclosure Package and the Prospectus. At the Effective Time and on the Closing Date and any Option Closing Date, there will be no options or warrants or other outstanding rights to purchase, agreements or obligations to issue or agreements or other rights to convert or exchange any obligation or security into, capital stock of the Company or securities convertible into or exchangeable for capital stock of the Company, except as disclosed in the Registration Statement, the Disclosure Package and the Prospectus or the grant of options, restricted stock or restricted stock units after the date of the Registration Statement, the Disclosure Package or the Prospectus under stock incentive plans or other stock plans of the Company and the sale of Common Stock pursuant to the Company’s employee stock purchase plan and its common stock purchase and dividend reinvestment plan. The information in the Registration Statement, Disclosure Package and the Prospectus insofar as it relates to all outstanding options and restricted stock units and other rights to acquire securities of the Company as of the dates referred to in the Registration Statement, the Disclosure Package and the Prospectus, is true and correct in all material respects.

          (n) The currently outstanding shares of the Company’s capital stock have been duly authorized and are validly issued, fully paid and non-assessable, and none of such outstanding shares of the Company’s capital stock has been issued in violation of any preemptive rights or similar rights of any security holder of the Company. The holders of the outstanding shares of the Company’s capital stock are not subject to personal liability solely by reason of being such holders. All previous offers and sales of the outstanding shares of the Company’s capital stock, whether described in the Registration Statement, Disclosure Package, the

Prospectus or otherwise, were made in conformity with applicable federal, state and foreign securities laws. The authorized capital stock of the Company, including, without limitation, the outstanding Common Stock, the Shares being issued, and the outstanding options to purchase shares of Common Stock conform in all material respects with the descriptions thereof in the Registration Statement, the Disclosure Package and the Prospectus, and such descriptions conform in all material respects with the instruments defining the same. The description of the Company’s stock plans, equity compensation plans and other equity arrangements, and the rights granted thereunder, set forth in the Registration Statement, the Disclosure Package and the Prospectus accurately and fairly presents, in all material respects, the information required to be shown with respect to such plans, arrangements and rights.

          (o) There are no contracts, agreements or understandings between the Company or any of its Subsidiaries and any person granting such person the right to require the Company to file a registration statement under the Act with respect to any securities of the Company owned or to be owned by such person or to require the Company to include such securities in the securities registered pursuant to the Registration Statement or in any securities being registered pursuant to any other registration statement filed by the Company under the Act.

          (p) The Shares have been duly and validly authorized, and, when issued and delivered against payment therefor as contemplated by this Agreement, the Shares will be validly issued, fully paid and non-assessable, and the holders thereof will not be subject to personal liability solely by reason of being such holders. The certificates representing the Shares are in proper legal form under, and conform in all respects to the requirements of, the New Hampshire Business Corporation Act. Neither the filing of the Registration Statement nor the offering or sale of Shares as contemplated by this Agreement gives any security holder of the Company any rights for or relating to the registration of any Common Stock or any other capital stock of the Company or any rights to convert or have redeemed or otherwise receive anything of value with respect to any other security of the Company.

          (q) No consent, approval, authorization, order, registration, license or permit of, or filing or registration with, any court, government, governmental agency, instrumentality or other regulatory body or official is required for the valid and legal execution, delivery and performance by the Company of this Agreement and the consummation of the transactions contemplated hereby, except (i) such as may be required for the registration of the Shares under the Act and the listing of the Shares on the NASDAQ Global Market, (ii) filings under the Exchange Act, and (iii) filings required for compliance with the applicable state securities or Blue Sky laws or the bylaws, rules and other pronouncements of the FINRA.

          (r) The Common Stock is registered pursuant to Section 12(g) of the Exchange Act. The issued and outstanding shares of Common Stock are listed on the NASDAQ Global Market. Neither the Company nor, to the Company’s knowledge, any other person has taken any action designed to cause, or likely to result in, the termination of the registration of the Common Stock under the Exchange Act. The Company has not received any notification that the SEC, the NASDAQ Global Market or FINRA is contemplating terminating such registration or inclusion. References to “knowledge” as applicable to the Company or any of its Subsidiaries shall mean the actual knowledge of the executive officers of the Company or its subsidiaries who are named in the Prospectus and Larry Goodhue.

          (s) The statements in the Registration Statement, the Disclosure Package and the Prospectus, insofar as they are descriptions of or references to contracts, agreements or other documents, are accurate in all material respects and present or summarize fairly, in all material respects, the information required to be disclosed under the Act or the Regulations, and there are no contracts, agreements or other documents, instruments or transactions of any character required to be described or referred to in the Registration Statement, the Disclosure Package or the Prospectus or to be filed as exhibits to the Registration Statement that have not been so described, referred to or filed, as required.

          (t) Each contract or other instrument (however characterized or described) to which the Company or any of the Subsidiaries is a party or by which any of their respective properties or businesses is bound or affected and which is material to the conduct of the business of the Company or the Subsidiaries, has been duly and validly executed by the Company or the Subsidiaries, as applicable and, to the knowledge of the Company, by the other parties thereto. Each such contract or other instrument is in full force and effect and is enforceable in all material respects against the parties thereto in accordance with its terms, except as enforcement may be limited by bankruptcy, insolvency or other similar laws affecting the enforcement of creditors’ rights generally and subject to applicability of general principles of equity, and neither the Company nor any of the Subsidiaries is, and to the knowledge of the Company, no other party thereto is, in default under any such contract or other instrument, and no event has occurred that, with the lapse of time or the giving of notice, or both, would constitute a default under any such contract or other instrument. All necessary consents under such contracts or other instruments to the disclosure in the Registration Statement, Disclosure Package and the Prospectus with respect thereto have been obtained.

          (u) The consolidated financial statements of the Company (including the notes thereto) filed as part of, or incorporated by reference in, the Prospectus and the Registration Statement, the Disclosure Package and the Prospectus present fairly, in all material respects, the financial position of the Company as of the respective dates thereof, and the results of operations and cash flows of the Company for the periods indicated therein, and have been prepared in conformity with generally accepted accounting principles. The supporting notes included in the Registration Statement, the Disclosure Package and the Prospectus fairly state in all material respects the information required to be stated therein in relation to the financial statements taken as a whole. The information included in the Registration Statement, the Disclosure Package and the Prospectus under the captions “Prospectus Summary — Summary Consolidated Financial Data,” “Use of Proceeds,” and “Capitalization” presents fairly the information shown therein and has been compiled on a basis consistent with that of the financial statements incorporated by reference in the Registration Statement, the Disclosure Package and the Prospectus. The unaudited pro forma adjustments to financial information in the Registration Statement, the Disclosure Package and the Prospectus have been properly applied to the historical amounts in the compilation of that information to reflect the sale by the Company of the Shares offered thereby at an assumed offering or actual price set forth in the Registration Statement, the Disclosure Package or the Prospectus, as the case may be, and the anticipated application of the estimated net proceeds therefrom substantially in accordance with the description set forth under the caption “Use of Proceeds” in the Prospectus.

          (v) Since the respective dates as of which information is given, or incorporated by reference, in the Registration Statement, the Disclosure Package and the Prospectus, except as otherwise stated therein, there has not been (i) any material adverse change (including, whether or not insured against, any material loss or damage to any material assets), or development involving a prospective material adverse change, in the Business Conditions of the Company or any of its Subsidiaries; (ii) any material adverse change, loss, reduction, termination or non-renewal of any material contract to which the Company or any of its Subsidiaries is a party; (iii) any transaction entered into by the Company or any of the Subsidiaries not in the ordinary course of its business that is material to the Company or any Subsidiary; (iv) any dividend or distribution of any kind declared, paid or made by the Company on its capital stock, except for and to the extent described in the Registration Statement, the Disclosure Package and the Prospectus; (v) any liabilities or obligations, direct or indirect, incurred by the Company or any of the Subsidiaries that are material to the Company or any of the Subsidiaries; (vi) any change in the capitalization of the Company or any of the Subsidiaries, except for issuances pursuant to the Company’s stock option or equity compensation plans or purchases by the Company’s dividend reinvestment plan; or (vii) any change in the indebtedness of the Company or any of the Subsidiaries that is material to the Company or any Subsidiary. Neither the Company nor any of the Subsidiaries has any contingent liabilities or obligations that are material and that are not expressly disclosed in the Registration Statement, the Disclosure Package and the Prospectus.

          (w) The Company has not distributed, and will not distribute, any offering material in connection with the offering and sale of the Shares other than the Registration Statement, the Disclosure Package, the Prospectus and other material, if any, permitted by the Act and the Regulations. Neither the Company nor, to the Company’s knowledge, any of its officers, directors or affiliates has (i) taken, nor shall the Company or such persons take, directly or indirectly, any action designed to, or that might be reasonably expected to, cause or result in stabilization or manipulation of the price of the Common Stock, or (ii) since the filing of the Prospectus (A) sold, bid for, purchased or paid anyone any compensation for soliciting purchases of, the Shares or (B) paid or agreed to pay to any person any compensation for soliciting another to purchase any other securities of the Company, other than payments to the Underwriters as provided in this Agreement.

          (x) The Company and the Subsidiaries have filed with the appropriate federal, state and local governmental agencies, and all foreign countries and political subdivisions thereof, all material tax returns that are required to be filed or have duly obtained extensions of time for the filing thereof and have paid all material taxes shown on such returns or otherwise due and all material assessments received by them to the extent that the same have become due. Neither the Company nor any of the Subsidiaries has executed or filed with any taxing authority, foreign or domestic, any agreement extending the period for assessment or collection of any income or other tax and none of them is a party to any pending action or proceeding by any foreign or domestic governmental agency for the assessment or collection of taxes, and no claims for assessment or collection of taxes have been asserted against the Company or any of the Subsidiaries that would have a Material Adverse Effect.

          (y) ParenteBeard LLC, which has given its report on certain financial statements included as part of or incorporated by reference in the Registration Statement, the Disclosure Package and the Prospectus, is an independent registered public accounting firm.

          (z) Neither the Company nor any of the Subsidiaries is in violation of, or in default under, any of the terms or provisions of (i) its Certificate or Articles of Incorporation, as the case may be, or Bylaws or similar governing instruments, (ii) any indenture, mortgage, deed of trust, contract, commitment or other agreement or instrument to which it is a party or by which it or any of its assets or properties is bound or affected, (iii) any law, rule, regulation, judgment, order or decree of any government or governmental agency, instrumentality or court, domestic or foreign, having jurisdiction over it or any of its properties or business, or (iv) any license, permit, certification, registration, approval, consent or franchise, except with respect to clause (ii), (iii) or (iv) above, where any such default would not reasonably be expected to have a Material Adverse Effect.

          (aa) Except as expressly disclosed in the Registration Statement, the Disclosure Package and the Prospectus, there are no claims, actions, suits, protests, proceedings, arbitrations, investigations or inquiries pending before, or, to the Company’s knowledge, threatened or contemplated by, any governmental agency, instrumentality, court or tribunal, domestic or foreign, or before any private arbitration tribunal to which the Company or any of the Subsidiaries is or may be made a party that could reasonably be expected to affect the validity of any of the outstanding Common Stock, or that, if determined adversely to the Company or any of the Subsidiaries would, in any case or in the aggregate, result in a Material Adverse Effect, nor to the Company’s knowledge is there any reasonable basis for any such claim, action, suit, protest, proceeding, arbitration, investigation or inquiry. There are no outstanding orders, judgments or decrees of any court, governmental agency, instrumentality or other tribunal enjoining the Company or any of the Subsidiaries from, or requiring the Company or any of the Subsidiaries to take or refrain from taking, any action, or to which the Company or any of the Subsidiaries or their properties, assets or businesses are bound or subject.

          (bb) Each of the Company and the Subsidiaries owns, or possesses adequate rights to use, or can acquire on reasonable terms, all patents, patent applications, trademarks, trademark registrations, applications for trademark registration, trade names, service marks, licenses, inventions, copyrights, know-how (including any unpatented and/or unpatentable proprietary or confidential technology, information, systems, design methodologies and devices or procedures developed or derived from or for the Company’s or the Subsidiaries’ business), trade secrets, confidential information, processes and formulations and other proprietary information necessary for, used in, or proposed to be used in, the conduct of the business of the Company and the Subsidiaries as described in the Registration Statement, the Disclosure Package and the Prospectus (collectively, the “Intellectual Property”). To the Company’s knowledge, neither the Company nor any of the Subsidiaries has infringed, is infringing or has received any notice of conflict with, the asserted rights of others with respect to the Intellectual Property that, individually or in the aggregate, if the subject of an unfavorable decision, ruling or finding, could materially adversely affect the Business Conditions of the Company and the Subsidiaries, taken as a whole, and the Company knows of no reasonable basis therefor. To the knowledge of the Company, no other parties have infringed upon or are in conflict with any Intellectual Property owned by the Company or its Subsidiaries. Neither the Company nor any

of the Subsidiaries is a party to, or bound by, any agreement pursuant to which royalties, honorariums or fees are payable by the Company or any of the Subsidiaries to any person by reason of the ownership or use of any Intellectual Property, except for software and computer applications used in the ordinary course of business.

          (cc) Each of the Company and the Subsidiaries has good and marketable title to all property described in the Registration Statement, the Disclosure Package and the Prospectus as being owned by it, free and clear of all liens, security interests, charges or encumbrances and the like, except such as are expressly described or referred to in the Registration Statement, the Disclosure Package and the Prospectus or such as do not materially adversely affect the Business Conditions or the conduct of the business of the Company and the Subsidiaries as described in the Registration Statement, the Disclosure Package and the Prospectus. Each of the Company and the Subsidiaries has insured its property against loss or damage by fire or other casualty, in amounts reasonably believed by the Company to be adequate, and maintains insurance against such other risks as management of the Company deems appropriate. All real and personal property owned and leased by the Company and the Subsidiaries, as described or referred to in the Registration Statement, the Disclosure Package and the Prospectus, is held by the Company or the Subsidiaries, as applicable, under valid and enforceable leases.

Any disclosure regarding the Plans required under the Act or the Exchange Act has been made in the Registration Statement, the Disclosure Package and the Prospectus and the documents incorporated therein. All Plans that are subject to ERISA are in compliance with ERISA, in all material respects, and, to the extent a Plan is treated by the Company (or, if applicable, by any Subsidiary or Related Employer) as satisfying the qualification requirements of Section 401(a) of the Code, such Plan is in compliance with the Code in all material respects and is the subject of a current favorable determination letter from the Internal Revenue Service as to its tax qualification, or such Plan has been submitted to the Internal Revenue Service for an updated determination letter and the Company expects that the

In addition to the payment of the Non-Accountable Expense Allowance, whether or not the transactions contemplated by this Agreement are consummated and regardless of the reason this Agreement is terminated, the Company will pay or cause to be paid, and bear or cause to be borne, all costs and expenses incident to the performance of the obligations of the Company under this Agreement, including: (i) the fees and expenses of the accountants and counsel for the Company incurred in the preparation of the Registration Statement and any post-effective amendments thereto (including financial statements and exhibits), the Disclosure Package, any Preliminary Prospectuses and the Prospectus and any amendments or supplements thereto; (ii) printing and mailing expenses associated with the Registration Statement and any post-effective amendments thereto, the Disclosure Package, any Preliminary Prospectus, the Prospectus, this Agreement and any related documents and any Blue Sky memorandum (any supplement thereto); (iii) the costs and expenses (other than fees and expenses of the Underwriter’s counsel, except any required fees incurred in connection with Blue Sky and FINRA filings or exemptions as provided herein) incident to the authentication, issuance, sale and delivery of the Shares to the Underwriter; (iv) the fees, expenses and all other costs of qualifying the Shares for sale under the securities or Blue Sky laws of those states in which the Shares are to be offered or sold, including the reasonable fees and expenses of Underwriter’s counsel and such local counsel as may have been reasonably required and retained for such purpose; (v) the fees, expenses and other costs of, or incident to, securing any review or approvals by or from FINRA, (other than the fees and expenses of the Underwriter’s counsel); (vi) the filing fees of the SEC; (vii) the cost of furnishing to the Underwriter copies of the Registration Statement, any Issuer Free Writing Prospectuses, any Preliminary Prospectuses and Prospectuses as herein provided; (viii) if applicable, the Company’s travel expenses in connection with meetings with the brokerage community and institutional investors; (ix) the costs and expenses associated with settlement in same day funds (including, but not limited to, interest or cost of funds expenses), if desired by the Company; (x) any fees or costs payable to the NASDAQ Global Market as a result of the offering; (xi) the cost of preparing, issuing and delivery to the Underwriter through the facilities of DTC of any certificates evidencing the Shares; (xii) the costs and charges of any transfer agent; (xiii) the reasonable costs of advertising the offering; (xiv) all taxes, if any, on the issuance, delivery and transfer of the Shares sold by the Company; and (xv) all other costs and expenses reasonably incident to the performance of the Company’s obligations hereunder that are not otherwise specifically provided for in this Section 6(a); provided, however, the Underwriter shall be responsible for their out-of-pocket expenses, including those associated with meetings with the brokerage community and institutional investors, other than the Company’s travel expenses, and the fees and expenses of their counsel for other than with respect to any applicable Blue Sky and FINRA matters.

          (b) If (i) the Underwriter is willing to proceed with the Offering, and the transactions contemplated by this Agreement are not consummated because the Company elects not to proceed with the offering for any reason or (ii) the Underwriter terminates this Agreement pursuant to Section 10 hereof, then the Company will reimburse the Underwriter for their accountable out-of-pocket expenses relating to the Offering (including but not limited to reasonable fees and disbursements to its counsel); provided, however, that such reimbursement shall not exceed $50,000. The Underwriter shall present a reasonable accounting of all expenses for which reimbursement is claimed hereunder.

          (h) The Underwriter shall have received at the Closing Date and any Option Closing Date certificates of the Chief Executive Officer and the Chief Financial Officer of the Company dated, as of the date of the Closing Date or Option Closing Date, as the case may be, and addressed to the Underwriter to the effect that (i) the representations and warranties of the Company in this Agreement are true and correct, as if made at and as of the Closing Date or the Option Closing Date, as the case may be, and that the Company has complied with all the

               (i) confirming they are independent certified public accountants within the meaning of the Act and the Regulations, and stating that the section of the Registration Statement under the caption “Experts” is correct insofar as it relates to them;

               (iii) stating that, on the basis of specified procedures, which included a reading of the latest available unaudited interim consolidated financial statements of the Company (with an indication of the date of the latest available unaudited interim financial statements), a reading of the minutes of the meetings of the shareholders and the Boards of Directors of the Company and the Subsidiaries and the Audit, Corporate Governance, Nominating and Compensation and Benefits Committees of such Boards and inquiries to certain officers and other employees of the Company and the Subsidiaries responsible for operational, financial and accounting matters and other specified procedures and inquiries, nothing has come to their attention that, except as specified in their letter, would cause them to believe (x) that at a specified date not more than five business days prior to the date of such letter, there was any change in the capital stock (other than the issuance of Common Stock under the Company’s Dividend Reinvestment Plan and Common Stock Purchase Plan) or increase in long-term debt of the Company (other than increases that the Registration Statement disclosed have occurred or may occur), in each case, as compared with the amounts shown in the Company’s December 31, 2008 audited balance sheets or any later dated Company balance sheet included in the Registration Statement or (y) that for the periods from and including January 1, 2009 to the date of the latest available unaudited financial statements of the Company, if any, there were any decreases, as compared to the corresponding periods in the prior year, in operating income or total or per share amounts of net income, except in all instances for changes, decreases or increases that the Registration Statement discloses have occurred or may occur.

All financial statements and schedules included in material incorporated by reference into the Prospectus shall be deemed included in the Registration Statement for purposes of this subsection.

               (v) provided, that the letter delivered on the Closing Date or the Option Closing Date, as the case may be, shall use a “cut-off” date no more than five business days prior to such Closing Date or such Option Closing Date, as the case may be.

          (j) All corporate and other proceedings and other matters incident to the authorization, form and validity of this Agreement and the form of the Registration Statement and Prospectus and all other legal matters related to this Agreement and the transactions contemplated hereby shall be reasonably satisfactory in all respects to counsel to the Underwriter.

If any condition to the Underwriter’s obligations hereunder to be fulfilled prior to or at the Closing Date or any Option Closing Date, as the case may be, is not fulfilled, the Underwriter may terminate this Agreement with respect to the Closing Date or such Option Closing Date, as applicable, or, if it so elects, waive any such conditions which have not been fulfilled or extend the time for their fulfillment. Any such termination shall be without liability of the Underwriter to the Company.

     8. Indemnification and Contribution.

          (a) The Company shall indemnify and hold harmless the Underwriter, and each person, if any, who controls the Underwriter within the meaning of the Act and the Exchange Act, against any and all loss, liability, claim, damage and expense whatsoever, including, but not limited to, any and all reasonable expenses incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever or in

connection with any investigation or inquiry of, or action or proceeding that may be brought against, the respective indemnified parties, arising out of or based upon any breach of the Company’s representations and warranties made in this Agreement or any untrue statements or alleged untrue statements of material fact contained in the Registration Statement, any Preliminary Prospectus, the Disclosure Package or the Prospectus, any application or other document filed in any jurisdiction in order to qualify all or any part of the Shares under the securities laws thereof or filed with the SEC or FINRA (in this Section 8 collectively called “application”), or the omission or alleged omission from any of the foregoing of a material fact required to be stated therein or necessary to make the statements therein not misleading; provided, however, that the foregoing indemnity shall not apply in respect of any statement or omission made in reliance upon and in conformity with written information furnished to the Company by the Underwriter expressly for use in any Preliminary Prospectus, the Registration Statement or Prospectus, or any amendment or supplement thereto, or in any application or in any communication to the SEC, as the case may be. The obligations of the Company under this Section 8(a) will be in addition to any liability the Company may otherwise have.

          (b) The Underwriter shall indemnify and hold harmless the Company, each of the directors of the Company, each of the officers of the Company who shall have signed the Registration Statement, and each other person, if any, who controls the Company within the meaning of the Act to the same extent as the foregoing indemnities from the Company to the Underwriter, but only with respect to any and all loss, liability, claim, damage or expense resulting from statements or omissions, or alleged statements or omissions, if any, made in any Preliminary Prospectus, the Disclosure Package, the Registration Statement or the Prospectus or any amendment or supplement thereof or any application or in any communication to the SEC in reliance upon, and in conformity with written information furnished to the Company by the Underwriter expressly for use in any Preliminary Prospectus, the Disclosure Package, the Registration Statement or the Prospectus or any amendment or supplement thereof, or any application or in any communication to the SEC, as the case may be. The obligations of the Underwriter under this Section 8(b) will be in addition to any liability which such Underwriter may otherwise have.

          (c) If any action, inquiry, investigation or proceeding is brought against any person in respect of which indemnification may be sought pursuant to Section 8(a) or (b) hereof, such person (hereinafter called the “indemnified party”) shall, promptly after notification of, or receipt of service of process for, such action, inquiry, investigation or proceeding, notify in writing the party or parties against whom indemnification is to be sought (hereinafter called the “indemnifying party”) of the institution of such action, inquiry, investigation or proceeding. The indemnifying party, upon the request of the indemnified party, shall assume the defense of such action, inquiry, investigation or proceeding, including, without limitation, the employment of counsel (reasonably satisfactory to such indemnified party) and payment of expenses. No indemnification provided for in this Section 8 shall be available to any indemnified party who shall fail to give such notice if the indemnifying party does not have knowledge of such action, inquiry, investigation or proceeding to the extent that such indemnifying party has been materially prejudiced by the failure to give such notice, but the omission to so notify the indemnifying party shall not relieve the indemnifying party otherwise than under this Section 8. Such indemnified party shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party

unless the employment of such counsel shall have been authorized in writing by the indemnifying party in connection with the defense of such action or if the indemnifying party shall not have, within a reasonable period of time in light of the circumstances, employed counsel reasonably satisfactory to the indemnified party, to have charge of the defense of such action, inquiry, investigation or proceeding or if such indemnified party or parties shall have been advised by counsel that there may be a conflict between the positions of the indemnifying party or parties and of the indemnified party or parties or that there may be legal defenses available to such indemnified party or parties different from or in addition to those available to the indemnifying party or parties, in any of which events the indemnified party or parties shall be entitled to select counsel to conduct the defense to the extent determined by such counsel to be necessary to protect the interests of the indemnified party or parties, and the reasonable fees and expenses of such counsel shall be borne by the indemnifying party. The indemnifying party shall be responsible for the fees and disbursements of only one such counsel so engaged by the indemnified party or parties as a group. Expenses covered by the indemnification in this Section 8 shall be paid by the indemnifying party promptly after written request is submitted by the indemnified party. In the event that it is determined that the indemnified party was not entitled to receive payments for expenses pursuant to this Section 8, the indemnified party shall return all sums that have been paid pursuant hereto. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action. Anything in this Section 8 to the contrary notwithstanding an indemnifying party shall not be liable for any settlement of a claim effected without its written consent, which consent shall not be unreasonably withheld.

          (d) If the indemnification provided for in this Section 8 is unavailable or insufficient to hold harmless an indemnified party under Section 8(a) or (b) hereof in respect of any losses, liabilities, claims, damages or expenses (or actions, inquiries, investigations or proceedings in respect thereof) referred to therein, except by reason of the failure to give notice as required in Section 8(c) hereof (provided that the indemnifying party does not have knowledge of the action, inquiry, investigation or proceeding and to the extent such party has been materially prejudiced by the failure to give such notice), then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, liabilities, claims, damages or expenses (or actions, inquiries, investigations or proceedings in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriter on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Underwriter on the other in connection with the statements or omissions which resulted in such losses, liabilities, claims or expenses (or actions, inquiries, investigations or proceedings in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriter on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bears to the total underwriting discount and commissions received by the

Underwriter, in each case as set forth in the table on the cover page of the Prospectus. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriter on the other hand and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

          The Company and the Underwriter agree that it would not be just and equitable if contributions to this Section 8(d) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to above in this Section 8(d). The amount paid or payable by an indemnified party as a result of the losses, liabilities, claims, damages or expenses (or actions, inquiries, investigations or proceedings in respect thereof) referred to above in this Section 8(d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8(d), (i) the Underwriter shall not be required to contribute any amount in excess of the underwriting discounts and commissions applicable to the Shares purchased by the Underwriter, and (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

     9. Representations and Agreements to Survive Delivery. Except as the context otherwise requires, all representations, warranties and agreements contained in this Agreement shall be deemed to be representations, warranties and agreements at the Closing Date and any Option Closing Date. All such representations, warranties and agreements of the Underwriter and the Company, including, without limitation, the indemnity and contribution agreements contained in Section 8 hereof and the agreements contained in Sections 6, 9 and 10 hereof, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of the Underwriter or any controlling person, and shall survive delivery of the Shares and termination of this Agreement, whether before or after the Closing Date or any Option Closing Date.

The time of the public offering, for the purpose of this Section 10, shall mean the time when any of the Shares are first released by the Underwriter for offering by dealers. The Underwriter and the Company may prevent the provisions of this Agreement (other than those contained in Section 6, 8, 9 and 10) from becoming effective without liability of any party to any other party, except as noted below, by giving the notice indicated in Section 10(c) hereof before the time the other provisions of this Agreement become effective.

          (b) The Underwriter shall have the right to terminate this Agreement at any time prior to the Closing Date or any Option Closing Date as provided in Section 7 or if any of the following have occurred: (a) since the respective dates as of which information is given in the Registration Statement and the Prospectus, any material adverse change or any development involving a prospective material adverse change in or affecting the Business Conditions of the Company and the Subsidiaries, whether or not arising in the ordinary course of business, that would, in the Underwriter’s opinion, make the offering or delivery of the Shares impracticable; (b) any outbreak or escalation of hostilities or other national or international calamity or crisis or change in economic, political or financial market conditions if the effect on the financial markets of the United States of such outbreak, calamity, crisis or change would, in the Underwriter’s opinion, make the offering or delivery of the Shares impracticable; (c) any suspension or limitation of trading generally in securities on the New York Stock Exchange, the American Stock Exchange or the NASDAQ Global Market or the over the counter market or any setting of minimum prices for trading or the promulgation of any federal or state statute, regulation, rule or order of any court or other governmental authority that in the Underwriter’s opinion materially and adversely affects trading on such exchange or over the counter market; (d) the enactment, publication, decree or other promulgation of any federal or state statute, regulation, rule or order of any court or other governmental authority which in the Underwriter’s opinion materially and adversely affects or will materially or adversely affect the Business Conditions of the Company and the Subsidiaries taken as a whole; (e) declaration of a banking moratorium by the United States, New York, California or Pennsylvania authorities; (f) the taking of any action by any federal, state or local government or agency in respect of its monetary or fiscal affairs that in the Underwriter’s opinion has a material adverse effect on the securities markets in the United States; or (g) trading in any securities of the Company shall have been suspended or halted by FINRA or the SEC.

At the request of any party, the other party shall re-execute original forms thereof and deliver them to the other party. No party shall raise the use of a facsimile machine to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine as a defense to the formation of a contract and each such party forever waives any such defense.

Pennichuck Corporation

Merrimack, New Hampshire 03054

Janney Montgomery Scott LLC

Philadelphia, PA 19103

Ladies and Gentlemen:

     This Lock-Up Agreement (this “Agreement”) is being delivered to you in connection with the Underwriting Agreement (the “Underwriting Agreement”) to be entered into by Pennichuck Corporation (the “Company”) and Janney Montgomery Scott LLC (the “Underwriter”) with respect to the public offering of common stock, $1.00 par value, of the Company (“Common Shares”). The undersigned is a director or executive officer of the Company and holds Common Shares. Capitalized terms used herein and not otherwise defined will have the meaning ascribed to them in the Underwriting Agreement.

     As an inducement to the Underwriter to underwrite the above-mentioned public sale of Common Shares, the undersigned hereby agrees, from the date hereof and for a period of ninety (90) days (the “Lock-Up Period”) from the date of the Final Prospectus Supplement related to the above-mentioned public sale of Common Shares (the “Supplement Date”), not to, directly or indirectly, sell, offer to sell, contract to sell, pledge, grant any option for the sale or purchase of, agree to sell or otherwise dispose of (collectively, “Disposition”), any Common Shares or any securities convertible into or exercisable or exchangeable for Common Shares beneficially owned by the undersigned now or on the Supplement Date, or with respect to which the undersigned now or on the Supplement Date has the power of Disposition, or enter into a transaction which would have the same effect, or enter into any swap, hedge or other arrangement that transfers, in whole or in part, any of the economic consequences of ownership of Common Shares, whether any such aforementioned transaction is to be settled by delivery of Common Shares or such other securities, in cash or otherwise, or publicly disclose the intention to make any such Disposition, or to enter into any such transaction, swap, hedge or other arrangement, without, in each case, the Underwriter’s prior written consent.

     In addition, the undersigned agrees that, without the Underwriter’s prior written consent, he or she will not, during the Lock-Up Period, make any demand for, or exercise any right with respect to, the registration of any Common Shares or any securities convertible into or exercisable or exchangeable for Common Shares.

     The foregoing Agreement and the representation shall not apply to (i) bona fide gifts of securities, (ii) transfers of securities to “affiliates” of the transferor if the transfers do not involve a public distribution or public offering, (iii) the exercise of any option or warrant to acquire Common Shares or settlement of any restricted stock or restricted stock units, including the delivery of Common Shares to the Company in satisfaction, in whole or part, of an option exercise price, provided that any Common Shares obtained by such exercise or settlement shall remain subject to this Agreement, (iv) any transfers of Common Shares pursuant to the terms of the Company’s 401(k) plan, (v) the pledge of Common Shares as collateral against loans by the undersigned, or (vi) the sale of Common Shares pledged as collateral to the extent necessary to satisfy such loans, provided that in the case of clauses (i), (ii), (v) or (vi) prior to the receipt of such Common Shares, the recipient of the Common Shares executes an agreement identical to this Agreement. The term “affiliate” shall have the meaning given such term in Rule 144 under the Act. The transferor shall notify the Underwriter in writing prior to engaging in any transaction or taking any other action that is subject to the terms of this Agreement during the Lock-Up Period.

     In furtherance of the foregoing, the Company and its transfer agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Agreement. The undersigned also agrees and consents to the entry of stock transfer instructions with the Company’s transfer agent against the transfer of any Common Shares or securities convertible into or exercisable or exchangeable for Common Shares.

     This Agreement shall be binding on the undersigned and the successors, heirs, personal representatives and assigns of the undersigned. This Agreement shall lapse and become null and void if the public offering shall not have been consummated on or before January 31, 2009. This Agreement shall be governed by, and construed in accordance with, the laws of the Commonwealth of Pennsylvania.
