Ladies and Gentlemen:

Middlesex Water Company, a New Jersey corporation (“Middlesex”), proposes, subject to the terms and conditions stated herein, to sell to the several Underwriters named in Schedule I hereto (the “Underwriters”), for whom Xxxxxx Xxxxxxxxxx Xxxxx LLC and Xxxxxx X. Xxxxx & Co., L.P. are serving as Representatives (the “Representatives”), an aggregate of 700,000 shares of Middlesex’s Common Stock, with no par value (“Common Stock”). The 700,000 shares of Common Stock to be sold to the Underwriters by Middlesex are referred to herein as the “Firm Shares.” The respective amounts of the Firm Shares to be purchased by the several Underwriters are set forth opposite their names in Schedule I hereto. The Firm Shares shall be offered to the public at a public offering price of $ per Firm Share (the “Offering Price”).

In order to cover over-allotments in the sale of the Firm Shares, the Underwriters may, at the Underwriters’ election and subject to the terms and conditions stated herein, purchase ratably in proportion to the amounts set forth opposite their respective names in Schedule I hereto, for the Underwriters’ own accounts up to 100,000 additional shares of Common Stock from Middlesex. Such 100,000 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.”

Middlesex and the Underwriters, intending to be legally bound, hereby confirm their agreement as follows:

1. Representations and Warranties of Middlesex. Middlesex represents and warrants to, and agrees with, the several Underwriters that:

(a) Middlesex has prepared, in conformity 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”) under the Act in effect at all applicable times, and has filed with the SEC a registration statement on Form S-3 (File No. 333-110786) and one or more amendments thereto for the purpose of registering the Shares under the Act. Copies of such registration statement and any amendments thereto, and all forms of the related prospectus contained therein, have been delivered to the Representatives. Any preliminary prospectus included in such registration statement or filed with the SEC pursuant to Rule 424(a) of the Regulations is hereinafter called a “Preliminary Prospectus.” The various parts of such registration statement, including all exhibits thereto, information incorporated by reference therein and the information contained in the form of final prospectus filed with the SEC pursuant to Rule 424(b) of the Regulations in accordance with Section 5(a) of this Agreement and deemed by virtue of Rule 424 of the Regulations to be part of the registration statement at the time it was declared effective, each as amended at the time the registration statement became effective, including the information (if any) deemed to be part of the registration statement at the time of effectiveness pursuant to Rule 430A of the Regulations, are hereinafter collectively called the “Registration Statement.” The final prospectus in the form included in the Registration Statement or first filed with the SEC pursuant to Rule 424(b) of the Regulations and any amendments or supplements thereto, including the information (if any) deemed to be part of that prospectus at the time of effectiveness pursuant to Rule 430A of the Regulations, is hereinafter called the “Prospectus.” All references to the Registration Statement, the Preliminary Prospectus and the Prospectus include all documents incorporated therein by reference. If Middlesex has filed an abbreviated registration statement to register additional Common Stock pursuant to Rule 462(b) under the Act (the “Rule 462 Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration Statement.

(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 Preliminary Prospectus, nor has the SEC instituted or threatened to institute proceedings with respect to such an order. No stop order suspending the sale of the Shares in any jurisdiction designated by the Representatives as provided for in Section 5(f) hereof has been issued, and no proceedings for that purpose have been instituted or threatened. Middlesex has complied in all material respects with all requests of the SEC, or requests of which Middlesex has been advised of any state or foreign securities commission in a state or foreign jurisdiction designated by the Representatives as provided for in Section 5(f) hereof, for additional information to be included in the Registration Statement, any Preliminary Prospectus or the Prospectus. Each Preliminary Prospectus conformed to all the requirements of

the Act and the Regulations as of its date in all material respects and did not as of its date 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. The Registration Statement, on the date on which it was declared effective by the SEC (the “Effective Date”) and when any post-effective amendment thereof shall become effective, and the Prospectus, at the time it is filed with the SEC including, if applicable, pursuant to Rule 424(b), and on the Closing Date (as defined in Section 3 hereof) and any Option Closing Date (as defined in Section 4(b) hereof), conformed and will conform in all material respects to all the requirements of the Act and the Regulations, and did not and will not, on any of such dates, include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading. The two preceding sentences do not apply to statements in or omissions from the Registration Statement or the Prospectus based upon written information furnished to Middlesex by or on behalf of any Underwriter through the Representatives expressly for use therein.

(c) 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 (“Exchange Act”) and the Exchange Act Regulations 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.

(d) There are no legal or governmental proceedings pending or, to the knowledge of Middlesex, threatened to which Middlesex or any of its Subsidiaries is a party or to which any of the properties of Middlesex or any Subsidiary are subject that are required to be described in the Registration Statement 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 or the Prospectus or to be filed as exhibits to the Registration Statement that are not described or filed as required.

(e) Middlesex is a corporation duly organized, validly existing and in good standing under the laws of the State of New Jersey, 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 Prospectus, and to execute, deliver and perform this Agreement. Each of Tidewater Utilities, Inc., a Delaware corporation (“Tidewater”), Pinelands Water Company, a New Jersey corporation (“Pinelands Water”), Pinelands Wastewater Company, a New Jersey corporation (“Pinelands Wastewater”), Utility Services Affiliates, Inc, a New Jersey corporation (“USA”), Utility Services Affiliates (Perth Amboy), Inc., a New Jersey corporation (“USA-PA”) and Bayview Water Company, a New Jersey corporation (“Bayview”) is a wholly owned subsidiary of Middlesex and together with each of Southern Shores Water Company, LLC, a Delaware limited liability company and wholly owned subsidiary of Tidewater (“Southern Shores”) and White Xxxxx Environmental Systems, Inc., a Delaware corporation (“White Xxxxx”) and wholly owned subsidiary of Tidewater, collectively, shall herein be referred to as the “Subsidiaries.” Each Subsidiary has been duly incorporated or formed and is an existing corporation or limited liability company, as the case may be, 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. Middlesex and the 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 (collectively, the “Business Conditions”) of Middlesex and the Subsidiaries taken as a whole. References to materiality as applicable to any of the Subsidiaries shall mean material to the Business Conditions of Middlesex and the Subsidiaries taken as a whole.

(f) 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 Middlesex, 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 Prospectus. Except for 4,218 shares of Artesian Resources Corporation, neither Middlesex nor the Subsidiaries owns any stock or other interest whatsoever, whether equity or debt, in any corporation, partnership or other entity other than Middlesex’s direct or indirect ownership of the Subsidiaries.

(g) This Agreement has been duly authorized, executed and delivered by Middlesex and constitutes its legal, valid and binding obligation, enforceable against Middlesex 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 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.

(h) 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 Middlesex’s or the Subsidiaries’ charter documents, 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 Middlesex or the Subsidiaries or require any payment by Middlesex or any of the Subsidiaries or impose any liability on Middlesex or any of the Subsidiaries pursuant to, any contract, indenture, mortgage, deed of trust, commitment or other agreement or instrument to which Middlesex or any of the Subsidiaries is a party or by which any of their properties are bound or affected other than this Agreement; (iii) assuming compliance with Blue Sky laws and the rules of the National Association of Securities Dealers, Inc. (the “NASD”) 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 Middlesex or the Subsidiaries or any of their respective properties or businesses; or (iv) result in a breach,

termination or lapse of Middlesex’s or the Subsidiaries’ corporate power and authority to own or lease and operate their respective properties and conduct their respective businesses.

(i) At the date or dates indicated in the Prospectus, Middlesex had the duly authorized and outstanding capitalization set forth in 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 Prospectus. On the Effective Date, 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 Middlesex or securities convertible into or exchangeable for capital stock of Middlesex, except as described in the Prospectus or the grant of options after the date of the Prospectus under option plans of Middlesex. The information in the Prospectus insofar as it relates to all outstanding options and other rights to acquire securities of Middlesex as of the Effective Date and immediately prior to the Closing Date and any Option Closing Date is true and correct in all material respects.

(j) The currently outstanding shares of Middlesex capital stock have been duly authorized and are validly issued, fully paid and non-assessable, and none of such outstanding shares of Middlesex capital stock has been issued in violation of any preemptive rights of any security holder of Middlesex. The holders of the outstanding shares of Middlesex 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 Middlesex capital stock, whether described in the Registration Statement or otherwise, were made in conformity with applicable federal, state and foreign securities laws. The authorized capital stock of Middlesex, 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 Prospectus, and such descriptions conform in all material respects with the instruments defining the same.

(k) There are no contracts, agreements or understandings between Middlesex or any of its Subsidiaries and any person granting such person the right to require Middlesex to file a registration statement under the Act with respect to any securities of Middlesex owned or to be owned by such person or to require Middlesex 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 Middlesex under the Act.

(l) When the Shares have been duly 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 Jersey Business Corporation Act, as amended (the “NJBCA”). Neither the filing of the Registration Statement nor the offering or sale of Shares as contemplated by this Agreement gives any security holder of Middlesex any rights for or relating to the registration of any Common Stock or any other capital stock of Middlesex or any rights to convert or have redeemed or otherwise receive anything of value with respect to any other security of Middlesex.

(m) 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 Middlesex of this Agreement and the consummation of the transactions contemplated hereby or described in the Prospectus, except (i) approval by the New Jersey Board of Public Utilities, which has been obtained, and (ii) such as may be required for the registration of the Shares under the Act and for compliance with the applicable state securities or Blue Sky laws or the Bylaws, rules and other pronouncements of the NASD.

(n) The Common Stock (including the Shares) is registered pursuant to Section 12(g) of the Exchange Act. The issued and outstanding shares of Common Stock are included for quotation on the Nasdaq National Market. Neither Middlesex nor, to Middlesex’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. Middlesex has not received any notification that the SEC or the NASD is contemplating terminating such registration or inclusion.

(o) The statements in the Registration Statement and 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 or Prospectus or to be filed as exhibits to the Registration Statement that have not been so described, referred to or filed, as required.

(p) Each contract or other instrument (however characterized or described) to which Middlesex 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 Middlesex’s, or the Subsidiaries’ business has been duly and validly executed by Middlesex or the Subsidiaries, as applicable, and, to the knowledge of Middlesex, by the other parties thereto. Each such contract or other instrument is in full force and effect and to Middlesex’s knowledge, is enforceable 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 Middlesex nor any of the Subsidiaries is, and to the knowledge of Middlesex, no other party is, in default thereunder 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 Prospectus with respect thereto have been obtained.

(q) The consolidated financial statements of Middlesex (including the notes thereto) included any Preliminary Prospectus, the Prospectus and the Registration Statement present fairly, in all material respects, the financial position of Middlesex as of the respective dates thereof, and the results of operations and cash flows of Middlesex for the periods indicated therein, all in conformity with generally accepted accounting principles. The supporting notes included in any Preliminary Prospectus, the Prospectus and the Registration Statement fairly state in all material respects the information required to be stated therein in relation to the

financial statements taken as a whole. The financial information included in the Prospectus under the captions “Prospectus Summary - Summary Consolidated Financial Information,” “Selected Consolidated Financial Information,” Use of Proceeds” and “Capitalization” presents fairly the information shown therein and has been compiled on a basis consistent with that of the audited financial statements included in the Registration Statement. The unaudited pro forma adjustments to financial information included in the Registration Statement have been properly applied to the historical amounts in the compilation of that information to reflect the sale by Middlesex of 700,000 shares of Common Stock offered thereby at an assumed offering or actual price set forth in the Preliminary Prospectus or the Prospectus, as the case may be, and the application of the estimated net proceeds therefrom.

(r) Since the respective dates as of which information is given in the Registration Statement 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 Middlesex; (ii) any material adverse change, loss, reduction, termination or non-renewal of any material contract to which Middlesex or any of the Subsidiaries is a party; (iii) any transaction entered into by Middlesex or any of the Subsidiaries not in the ordinary course of its business that is material to Middlesex or any of the Subsidiaries; (iv) any dividend or distribution of any kind declared, paid or made by Middlesex on its capital stock, except for and to the extent described in the Prospectus; (v) any liabilities or obligations, direct or indirect, incurred by Middlesex or any of the Subsidiaries that are material to Middlesex or any of the Subsidiaries; (vi) except for purchases of Common Stock by the Middlesex Dividend Reinvestment Plan, any change in the capitalization of Middlesex or any of the Subsidiaries; or (vii) any change in the indebtedness of Middlesex or any of the Subsidiaries that is material to Middlesex or the Subsidiaries. Neither Middlesex nor the Subsidiaries has any contingent liabilities or obligations that are material and that are not expressly disclosed in the Prospectus.

(s) Middlesex 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, a Preliminary Prospectus, the Prospectus and other material, if any, permitted by the Act and the Regulations. Neither Middlesex nor any of its officers, directors or affiliates has (i) taken, nor shall Middlesex 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 Registration Statement (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 Middlesex.

(t) Middlesex and the Subsidiaries have filed with the appropriate federal, state and local governmental agencies, and all foreign countries and political subdivisions thereof, all tax returns that are required to be filed or have duly obtained extensions of time for the filing thereof and have paid all 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 Middlesex 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 neither 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 Middlesex or any of the Subsidiaries that might materially adversely affect the Business Conditions of Middlesex or any of the Subsidiaries.

(u) Deloitte & Touche LLP, which has given its report on certain financial statements included as part of the Registration Statement, is a firm of independent certified public accountants as required by the Act and the Regulations with respect to Middlesex.

(v) Neither Middlesex nor any of the Subsidiaries is in violation of, or in default under, any of the terms or provisions of (i) its charter documents 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 be reasonably expected to have a material adverse effect on the Business Conditions of Middlesex or any of the Subsidiaries.

(w) Except as expressly disclosed in the Prospectus, there are no claims, actions, suits, protests, proceedings, arbitrations, investigations or inquiries pending before, or, to Middlesex’s knowledge, threatened or contemplated by, any governmental agency, instrumentality, court or tribunal, domestic or foreign, or before any private arbitration tribunal to which Middlesex 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 Middlesex or any of the Subsidiaries would, in any case or in the aggregate, result in any material adverse change in the Business Conditions of Middlesex or any of the Subsidiaries, nor to Middlesex’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 Middlesex or any of the Subsidiaries from, or requiring Middlesex or any of the Subsidiaries to take or refrain from taking, any action, or to which Middlesex or any of the Subsidiaries or their properties, assets or businesses are bound or subject.

(x) Each of Middlesex and the Subsidiaries owns, or possesses adequate rights to use, 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 Middlesex’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 Middlesex and the Subsidiaries as described in the Prospectus (collectively, the “Intellectual Property”). To Middlesex’s knowledge, neither Middlesex nor any of the Subsidiaries has infringed, is infringing nor have 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 Middlesex and the Subsidiaries, taken as

a whole. To the knowledge of Middlesex, no other parties have infringed upon or are in conflict with any Intellectual Property owned by Middlesex or its Subsidiaries. Neither Middlesex nor any of the Subsidiaries is a party to, or bound by, any agreement pursuant to which royalties, honorariums or fees are payable by Middlesex or any of the Subsidiaries to any person by reason of the ownership or use of any Intellectual Property, except for such royalties, honorariums or fees associated with commercially available software and computer applications.

(y) Each of Middlesex and the Subsidiaries has good and marketable title to all property described in 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 Prospectus or such as do not materially adversely affect the Business Conditions or the conduct of the business of Middlesex and the Subsidiaries as described in the Prospectus. Each of Middlesex and the Subsidiaries has insured its property against loss or damage by fire or other casualty, in amounts reasonably believed by Middlesex to be adequate, and maintains insurance against such other risks as management of Middlesex deems appropriate. All real and personal property leased by Middlesex and the Subsidiaries as described or referred to in the Prospectus, is held by Middlesex and the Subsidiaries as applicable, under valid leases. The executive offices and facilities of Middlesex and the Subsidiaries (the “Premises”), and all operations presently or formerly conducted thereon by Middlesex or the Subsidiaries or any predecessors thereof, are now and, since Middlesex or the Subsidiaries began to use such Premises, always have been and, to the knowledge of Middlesex prior to when Middlesex or the Subsidiaries began to use such Premises, always had been, in compliance in with all federal, state and local statutes, ordinances, regulations, rules, standards and requirements of common law concerning or relating to industrial hygiene and the protection of health and the environment (collectively, the “Environmental laws”), except to the extent that any failure in such compliance would not materially adversely affect the Business Conditions of Middlesex or the Subsidiaries. To the knowledge of Middlesex, the facilities of Middlesex and the Subsidiaries produce water of sufficient quality and quantity to supply the current and planned customers and service areas served by Middlesex and the Subsidiaries, and are not subject to any restriction on groundwater withdrawal under any federal, state or local law, regulation, rule, order or permit, except as expressly described in the Prospectus or as provided in State of Delaware allocation permits and such as do not materially adversely affect the Business Conditions or the conduct of the business of Middlesex and the Subsidiaries as described in the Prospectus. To the knowledge of Middlesex, there are no conditions on, about, beneath or arising from the Premises, in close proximity to the Premises or at any other location that (i) might give rise to liability, the imposition of a statutory lien upon Middlesex or the Subsidiaries, (ii) require a “Response,” “Removal” or “Remedial Action,” as defined herein, under any of the Environmental laws by Middlesex or any of the Subsidiaries, or (iii) affect the quality of the groundwater withdrawn by Middlesex or the Subsidiaries, and that in any such case described in (i), (ii) or (iii) would materially adversely affect the Business Conditions of Middlesex, except as described in the Prospectus. Except as expressly disclosed in the Prospectus, or which will not materially adversely affect the Business Conditions of Middlesex (i) neither Middlesex nor the Subsidiaries has received notice or has knowledge of any claim, demand, investigation, regulatory action, suit or other action instituted or threatened against Middlesex or the Subsidiaries or any portion of the Premises or any parcel in close proximity to the Premises relating to any of the Environmental laws and (ii) neither Middlesex nor the Subsidiaries has received any notice of material violation, citation, complaint, order, directive,

request for information or response thereto, notice letter, demand letter or compliance schedule to or from any governmental or regulatory agency arising out of or in connection with “hazardous substances” (as defined by applicable Environmental laws) on, about, beneath, arising from or generated at the Premises, near the Premises or at any other location. As used in this subsection, the terms “Response,” “Removal” and “Remedial Action” shall have the respective meanings assigned to such terms under Sections 101(23)-101(25) of the Comprehensive Environmental Response, Compensation and Liability Act, as amended by the Superfund Amendments and Reauthorization Act, 42 U.S.C. 9601(23)-9601(25).

(z) Each of Middlesex and the Subsidiaries maintain a system of internal accounting controls sufficient to provide reasonable assurances that: (i) transactions are executed in accordance with management’s general or specific authorization; (ii) transactions are recorded as necessary in order to permit preparation of financial statements in accordance with generally accepted accounting principles and to maintain accountability for assets; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the recorded accountability for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

(aa) Middlesex, the Subsidiaries and any Related Employer (which for purposes of this Paragraph means any entity that with Middlesex or the Subsidiaries is a member of a controlled group of corporations within the meaning of Section 414(b) of the Internal Revenue Code of 1986 as amended (the “Code”), is, individually or collectively, a trade or business under common control within the meaning of Section 414(c) of the Code, or is a member of the same affiliated service group within the meaning of Section 414(m) of the Code) have established, maintain, contribute to, are required to contribute to, are a party to, or are bound by certain pension, retirement, profit-sharing plans, deferred compensation, bonus, or other incentive plans, or medical, vision, dental, or other health plans, or life insurance or disability plans, or any other employee benefit plans, programs, arrangements, agreements, or understandings, some of which are subject to the Employee Retirement Income Security Act of 1974 as amended (“ERISA”) and the rules and regulations thereunder (“Plans”). Any disclosure regarding the Plans required under the Act or the Exchange Act has been made in 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 intended to be tax-qualified within the meaning 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. No Plan is an employee pension benefit plan that is subject to Part 3 of Subtitle B of Title I of ERISA, a defined benefit plan subject to Title IV of ERISA, or a multiemployer plan. None of Middlesex, the Subsidiaries or any Related Employer maintains or has maintained retiree life or retiree health insurance plans that are employee welfare benefit plans providing for continuing benefit or coverage for any employee or any beneficiary of any employee after such employee’s termination of employment, except as required by Section 4980B of the Code and except as disclosed in the Prospectus. No fiduciary or other party in interest with respect to any of the Plans has caused any of such Plans to engage in a prohibited transaction as defined in Section 406 of ERISA and Section 4975 of the Code. As used in this subsection, the terms “defined benefit plan,” “employee benefit plan,” “employee pension benefit plan,” “employee welfare benefit plan,” “fiduciary” and “multiemployer plan” shall have the respective meanings assigned to such terms in Section 3 of ERISA.

(bb) No labor dispute exists with Middlesex’s or the Subsidiaries’ employees, and to Middlesex’s knowledge, no such labor dispute is threatened. Middlesex has no knowledge of any existing or threatened labor disturbance by the employees of any of the principal suppliers, contractors or customers of Middlesex or any of the Subsidiaries that would materially adversely affect the Business Conditions of Middlesex or any of the Subsidiaries. None of Middlesex’s or the Subsidiaries’ employees is covered by a collective bargaining agreement and no union organizing activity exists with respect to any of such employees.

(cc) Neither Middlesex nor the Subsidiaries has incurred any liability for any finder’s fees or similar payments in connection with the transactions contemplated herein other than as disclosed in the Prospectus.

(dd) Middlesex is familiar with the Investment Company Act of 1940, as amended (the “1940 Act”), and the rules and regulations thereunder, and has in the past conducted, and Middlesex intends to conduct, its affairs in such a manner as to ensure that it will not be an “investment company” or an entity “ controlled” by an investment company within the meaning of the 1940 Act and the rules and regulations thereunder.

(ee) Middlesex and its Subsidiaries have received all permits, licenses, franchises, authorizations, registrations, qualifications and approvals (collectively, “Permits”) of governmental or regulatory authorities as may be required of them to own their properties and conduct their businesses in the manner described in the Prospectus, subject to such qualifications as may be set forth in the Prospectus; and Middlesex and its Subsidiaries have fulfilled and performed all of their material obligations with respect to such Permits, and no event has occurred which allows or, after notice or lapse of time or both, would allow revocation or termination thereof or result in any other material impairment of the rights of the holder of any such Permit, subject in each case to such qualifications as may be set forth in the Prospectus; and, except as described in the Prospectus, such Permits contain no restrictions that materially affect the ability of Middlesex and its Subsidiaries to conduct their businesses.

(ff) No statement, representation, warranty or covenant made by Middlesex or any of the Subsidiaries in this Agreement or in any certificate or document required by this Agreement to be delivered to the Representatives is, or as of the Closing Date or any Option Closing Date will be, inaccurate, untrue or incorrect in any material respect. No transaction has occurred or is proposed between or among Middlesex or any of the Subsidiaries and any of their respective officers, directors or stockholders or any affiliate of the foregoing, or any affiliate of the foregoing that is required to be described in and is not described in the Registration Statement and the Prospectus.

(gg) None of Middlesex, the Subsidiaries or any officer, director, employee, partner, agent or other person acting on behalf of Middlesex or the Subsidiaries has, directly or indirectly, given or agreed to give any money, property or similar benefit or consideration to any customer or supplier (including any employee or agent of any customer or supplier) or official or employee of any agency or instrumentality of any government (foreign or domestic) or political party or candidate for office (foreign or domestic) or any other person who was, is or in the future may be in a position to affect the Business Conditions of Middlesex or any of the Subsidiaries or any actual or proposed business transaction of Middlesex or any of the

Subsidiaries that (i) could subject Middlesex or any of the Subsidiaries to any liability (including, but not limited to, the payment of monetary damages) or penalty in any civil, criminal or governmental action or proceeding that would have a material adverse effect on the Business Conditions of Middlesex or any of the Subsidiaries or (ii) with respect to Middlesex, the Subsidiaries, or any officer or director thereof, violates any law, rule or regulation to which Middlesex or any of the Subsidiaries is subject.

Any certificate signed by any officer of Middlesex or any of the Subsidiaries in such capacity and delivered to the Representatives or to counsel for the Underwriters pursuant to this Agreement shall be deemed a representation and warranty by Middlesex or the Subsidiaries as the case may be, to the several Underwriters as to the matters covered thereby.

On the basis of the representations, warranties, covenants and agreements contained herein, but subject to the terms and conditions set forth herein, Middlesex shall sell the Firm Shares to the several Underwriters at the Offering Price less the Underwriting Discounts and Commissions shown on the cover page of the Prospectus, and the Underwriters, severally and not jointly, shall purchase from Middlesex on a firm commitment basis, at the Offering Price less the Underwriting Discounts and Commissions shown on the cover page of the Prospectus, the respective amounts of the Firm Shares set forth opposite their names on Schedule I hereto. In making this Agreement, each Underwriter is contracting severally and not jointly, and except as provided in Sections 4 and 11 hereof, the agreement of each Underwriter is to purchase only that number of Shares specified with respect to that Underwriter in Schedule I hereto. The Underwriters shall offer the Shares to the public as set forth in the Prospectus.

3. Payment and Delivery. The Firm Shares shall be issued in the form of one or more fully registered global securities (the “Global Securities”) in book-entry form in such denominations and registered in the name of the nominee of The Depository Trust Company (“DTC”) or in such names as the Representatives may request upon at least 48 hours’ prior notice to Middlesex, and shall be delivered by or on behalf of Middlesex to the Representatives for the account of such Underwriter, against payment by such Underwriter on its behalf of the purchase price therefor by wire transfer of immediately available funds to such accounts as Middlesex shall designate in writing (with all costs and expenses incurred by the Underwriters in connection with such settlement in immediately available funds, including, but not limited to, interest or cost of funds and expenses, to be borne by Middlesex). The closing of the sale and purchase of the Firm Shares shall be held at the offices of Xxxxxxx Xxxxx Xxxxxxx & Xxxxxxxxx, LLP, 0000 Xxxxxx Xxxxxx, Xxxxxxxxxxxx, Xxxxxxxxxxxx for the respective accounts of the Underwriters. Such payment and delivery will be made at 10:00 a.m., Philadelphia, Pennsylvania time, on the third business day after the date of this Agreement, or at such other time on the same or such other date, not later than seven business days thereafter as shall be designated in writing by the Representatives.

4. Option to Purchase Optional Shares.

(a) For the purposes of covering any over-allotments in connection with the distribution and sale of the Firm Shares as contemplated by the Prospectus, subject to the terms and conditions herein set forth, the several Underwriters are hereby granted an option by Middlesex to purchase all or any part of the Optional Shares (the “Over-allotment Option”). The purchase price to be paid for the Optional Shares shall be the Offering Price less the Underwriting Discounts and Commissions shown on the cover page of the Prospectus. The Over-allotment Option granted hereby may be exercised by the Representatives on behalf of the several Underwriters as to all or any part of the Optional Shares at any time and from time to time within 30 days after the date of the Prospectus. No Underwriter shall be under any obligation to purchase any Optional Shares prior to an exercise of the Over-allotment Option.

(b) The Over-allotment Option granted hereby may be exercised by the Representatives on behalf of the several Underwriters by giving notice to Middlesex by a letter sent by registered or certified mail, postage prepaid, telex, telegraph, telegram or facsimile (such notice to be effective when received), addressed as provided in Section 12 hereof, setting forth the number of Optional Shares to be purchased, the date and time for delivery of and payment for the Optional Shares and stating that the Optional Shares referred to therein are to be used for the purpose of covering over-allotments in connection with the distribution and sale of the Firm Shares. If such notice is given at least two full business days prior to the Closing Date, the date set forth therein for such delivery and payment shall be not earlier than the Closing Date. If such notice is given after two full business days prior to the Closing Date, the date set forth therein for such delivery and payment shall be a date selected by the Representatives not later than five full business days after the exercise of the Over-allotment Option. The date and time set forth in such a notice is referred to herein as an “Option Closing Date,” and a closing held pursuant to such a notice is referred to herein as an “Option Closing.” Upon each exercise of the Over-allotment Option, and on the basis of the representations, warranties, covenants and agreements herein contained, and subject to the terms and conditions herein set forth, the several Underwriters shall become severally, but not jointly, obligated to purchase from Middlesex the number of Optional Shares specified in each notice of exercise of the Over-allotment option (allocated among them in accordance with Section 4(c) hereof).

(c) The number of Optional Shares to be purchased by each Underwriter pursuant to each exercise of the Over-allotment Option shall be the number that bears the same ratio to the aggregate number of Optional Shares being purchased through such Over-allotment Option exercise as the number of Firm Shares opposite the name of such Underwriter in Schedule I hereto bears to the total number of all Firm Shares. Notwithstanding the foregoing, the number of Optional Shares purchased and sold pursuant to each exercise of the Over-allotment Option shall be subject to such adjustment as the Representatives may approve to eliminate fractional shares and subject to the provisions for the allocation of Optional Shares purchased for the purpose of covering over-allotments set forth in the agreement entered into by and among the Underwriters in connection herewith (the “Agreement Among Underwriters”).

(d) The Optional Shares shall be issued in the form of one or more Global Securities in book-entry form in such denominations and registered in the name of the nominee of DTC or in such names as the Representatives may request upon at least 48 hours’ prior notice

to Middlesex, and shall be delivered by or on behalf of Middlesex to the Representatives for the account of such Underwriter, against payment by such Underwriter on its behalf of the purchase price therefor by wire transfer of immediately available funds to such accounts as Middlesex shall designate in writing (with all costs and expenses incurred by the Underwriters in connection with such settlement in immediately available funds, including, but not limited to, interest or cost of funds and expenses, to be borne by Middlesex). The closing of the sale and purchase of the Optional Shares shall be held at the offices of Xxxxxxx Xxxxx Xxxxxxx & Ingersoll, LLP, 0000 Xxxxxx Xxxxxx, Xxxxxxxxxxxx, Xxxxxxxxxxxx for the respective accounts of the Underwriters. Such payment and delivery will be made at 10:00 a.m., Philadelphia, Pennsylvania time, on the third business day after the date of each exercise of the Over-allotment Option, or at such other times on the same or such other dates, not later than seven business days thereafter as shall be designated in writing by the Representatives. Such times and dates are referred to herein as the “Option Closing Dates.” Middlesex shall make the Global Securities representing the Optional Shares available for examination by the Representatives and counsel for the Underwriters at the Philadelphia correspondent office of Middlesex’s transfer agent not less than one full business day prior to each Option Closing Date.

5. Certain Covenants and Agreements of Middlesex. Middlesex covenants and agrees with the several Underwriters as follows:

(a) If Rule 430A of the Regulations is employed, Middlesex will timely file the Prospectus pursuant to and in compliance with Rule 424(b) of the Regulations and will advise the Representatives of the time and manner of such filing.

(b) Middlesex will not file with the SEC, the Prospectus, any amendment or supplement to the Prospectus or any amendment to the Registration Statement, unless the Representatives have received a reasonable period of time to review any such proposed amendment or supplement and consented to the filings thereof and will use its best efforts to cause any such amendment to the Registration Statement to be declared effective as promptly as possible. Upon reasonable request of the Representatives or counsel for the Underwriters, Middlesex will promptly prepare and file with the SEC, in accordance with the Regulations of the SEC, any amendments to the Registration Statement or amendments or supplements to the Prospectus that may be necessary or advisable in connection with the distribution of the Shares by the several Underwriters and will use its best efforts to cause any such amendment to the Registration Statement to be declared effective as promptly as possible. If required, Middlesex will file any amendment or supplement to the Prospectus with the SEC in the manner and within the time period required by Rule 424(b) under the Act. Middlesex will advise the Representatives, promptly after receiving notice thereof, of the time when the Registration Statement or any amendment thereof has been filed or declared effective or the Prospectus or any amendment or supplement thereto has been filed and will provide evidence to the Representatives of each filing or effectiveness.

(c) Middlesex will advise the Representatives immediately, and confirm such advice in writing, (i) when any post-effective amendment to the Registration Statement is filed with the SEC under Rule 462(c) under the Act or otherwise, (ii) any Rule 462(b) Registration Statement is filed, (iii) of the receipt of any comments from the SEC concerning the Registration Statement, (iv) when any post-effective amendment to the Registration Statement becomes

effective, or when any supplement to the Prospectus or any amended Prospectus has been filed, (v) of any request of the SEC for amendment or supplementation of the Registration Statement or Prospectus or for additional information, (vi) during the period when the Prospectus is required to be delivered under the Act and Regulations, of the happening of any event as a result of which the Registration Statement or the Prospectus would include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein not misleading, (vii) during the period noted in clause (vi) above, of the need to amend the Registration Statement or supplement the Prospectus to comply with the Act, (viii) of the issuance by the SEC of any stop order suspending the effectiveness of the Registration Statement or of any order preventing or suspending the use of any Preliminary Prospectus or the Prospectus, and (ix) of the suspension of the qualification of any of the Shares for offering or sale in any jurisdiction in which the Underwriters intend to make such offers or sales, or the initiation or threatening of any proceedings for any of such purposes known to Middlesex. Middlesex will use its best efforts to prevent the issuance of any such stop order or of any order preventing or suspending such use, and if any such order is issued, to obtain as soon as possible the lifting thereof.

(d) Middlesex has delivered to the Representatives, without charge, as many copies of each Preliminary Prospectus as the Representatives have reasonably requested. Middlesex will deliver to the Representatives, without charge, from time to time during the period when delivery of the Prospectus is required under the Act, such number of copies of the Prospectus (as supplemented or amended) as the Representatives may reasonably request. Middlesex hereby consents to the use of such copies of the Preliminary Prospectus and the Prospectus for purposes permitted by the Act, the Regulations and the securities or Blue Sky laws of the states or foreign jurisdictions in which the Shares are offered by the several Underwriters and by all dealers to whom Shares may be sold, both in connection with the offering and sale of the Shares and for such period of time thereafter as the Prospectus is required by the Act to be delivered in connection with sales by any Underwriter or dealer. Middlesex has furnished or will furnish to the Representatives at least one original signed copy of the Registration Statement as originally filed and of all amendments and supplements thereto, whether filed before or after the Effective Date, at least one copy of all exhibits filed therewith and of all consents and certificates of experts, and will deliver to the Representatives such number of conformed copies of the Registration Statement, including financial statements and exhibits, and all amendments thereto, as the Representatives may reasonably request.

(e) Middlesex will comply with the Act, the Regulations, the Exchange Act and the Exchange Act Regulations so as to permit the continuance of sales of and dealings in the Shares for as long as may be necessary to complete the distribution of the Shares as contemplated hereby.

(f) Middlesex will furnish such information and pay such filing fees and other expenses as may be required, and otherwise cooperate in the registration or qualification of the Shares, or exemption therefrom, for offering and sale by the several Underwriters and by dealers under the securities or Blue Sky laws of such jurisdictions in which the Representatives determine to offer the Shares, after consultation with Middlesex, and will file such consents to service of process or other documents necessary or appropriate in order to effect such registration or qualification; provided, however, that no such qualification shall be required in any

jurisdiction where, solely as a result thereof, Middlesex would be subject to taxation or qualification as a foreign corporation doing business in such jurisdiction where it is not now so qualified or to take any action which would subject it to service of process in suits, other than those arising out of the offering or sale of the Shares, in any jurisdiction where it is not now so subject. Middlesex will, from time to time, prepare and file such statements and reports as are or may be required to continue such qualification in effect for so long a period as is required under the laws of such jurisdictions for such offering and sale. Middlesex will furnish such information and pay such filing fees and other expenses as may be required, and otherwise cooperate in the inclusion of the Shares for quotation on the Nasdaq National Market. Middlesex will, from time to time, prepare and file such statements and reports as are or may be required to continue such qualification in effect for a period of three years from the Effective Date.

(g) Subject to Section 5(b) hereof, in case of any event (occurring at any time within the period during which, in the opinion of counsel for the Underwriters, a prospectus is required to be delivered under the Act or the Regulations), as a result of which any Preliminary Prospectus or the Prospectus, as then amended or supplemented, would contain, in the opinion of counsel for the Underwriters, an untrue statement of a material fact, or omit to state any material fact necessary in order to make the statements therein not misleading, or, if it is necessary at any time to amend any Preliminary Prospectus or the Prospectus to comply with the Act or the Regulations or any applicable securities or Blue Sky laws, Middlesex promptly will prepare and file with the SEC, and any applicable state and foreign securities commission, an amendment, supplement or document that will correct such statement or omission or effect such compliance and will furnish to the several Underwriters such number of copies of such amendments, supplements or documents (in form and substance satisfactory to the Representatives and counsel for the Underwriters) as the Representatives may reasonably request. For purposes of this Section 5(g), Middlesex will provide such information to the Representatives, the Underwriters’ counsel and counsel to Middlesex as shall be necessary to enable such persons to consult with Middlesex with respect to the need to amend or supplement the Registration Statement, Preliminary Prospectus or Prospectus or file any document, and shall furnish to the Representatives and the Underwriters’ counsel such further information as each may from time to time reasonably request.

(h) Middlesex will make generally available to its security holders not later than 45 days after the end of the period covered thereby, an earnings statement of Middlesex (which need not be audited unless required by the Act or the Regulations) that shall comply with Section 11(a) of the Act and Rule 158 thereunder and cover a period of at least 12 consecutive months beginning not later than the first day of Middlesex’s fiscal quarter next following the Effective Date (or, if later, the effective date of the Rule 462(b) Registration Statement).

(k) Middlesex has caused each person listed on Schedule II hereto to execute an agreement (a “Lock-up Agreement”) in form and substance satisfactory to the Representatives and the Underwriters’ counsel which provides that from the date of the Lock-up Agreement and for a period of 90 days from the Effective Date, such persons will not, without the prior written consent of the Representatives, directly or indirectly, sell, offer or contract to sell, pledge, grant any option for sale or purchase of, agree to sell or otherwise dispose of (collectively, “Disposition”) any shares of Common Stock (or any securities convertible into or exercisable or exchangeable for any shares of Common Stock) 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 Stock, or publicly disclose the intention to make any such Disposition or enter into any such transaction, swap, hedge or other arrangement. Middlesex has delivered such agreements to the Representatives prior to the date of this Agreement. Appropriate stop transfer instructions will be issued by Middlesex to the transfer agent for the Common Stock and a copy of such instructions will be delivered to the Representatives.

(l) As of the date of the Lock-up Agreement and for a period of 90 days after the Effective Date, Middlesex will not, without the prior written consent of the Representatives, issue or make a Disposition of any Common Stock or any securities convertible into or exercisable or exchangeable for any Common Stock 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 Stock, or publicly disclose the intention to issue or make any such Disposition or enter into any such transaction, swap, hedge or other arrangement, except (i) the issuance of Common Stock upon the exercise of currently outstanding options and warrants as described in the Prospectus, (ii) the grant of options to purchase Common Stock under Middlesex’s currently outstanding stock option plans and the issuance of Common Stock upon the exercise thereof, (iii) the issuance of Common Stock under Middlesex’s Dividend Reinvestment Plan and 401(k) Plan and (iv) the issuance of Common Stock under Middlesex’s Restricted Stock Plan.

(a) Middlesex shall indemnify and hold harmless each Underwriter, and each person, if any, who controls each Underwriter within the meaning of the 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 Middlesex’ representations and warranties made in this Agreement or any untrue statements or alleged untrue statements of material fact contained in any Preliminary Prospectus, the Registration Statement 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 the NASD (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 Middlesex by any Underwriter through the Representatives 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; and further provided, however, that the indemnification contained in this Section 8(a) with respect to any Preliminary Prospectus shall not inure to the benefit of any Underwriter (or to the benefit of any person controlling such Underwriter) on account of any such loss, claim, liability or expense arising from the sale of the Shares by such Underwriter to any person if a copy of the Prospectus shall not have been delivered or sent to such person within the time required by the Act and the regulations thereunder, and the untrue statement or alleged untrue statement or omission or alleged omission of a material fact contained in such Preliminary Prospectus was corrected in the Prospectus, provided that Middlesex has delivered the Prospectus to the several Underwriters in requisite quantity on a timely basis to permit such delivery or sending. The obligations of Middlesex under this Section 8(a) will be in addition to any liability Middlesex may otherwise have.

(b) Each Underwriter severally and not jointly shall indemnify and hold harmless Middlesex, each of the directors of Middlesex, each of the officers of Middlesex who shall have signed the Registration Statement, and each other person, if any, who controls Middlesex within the meaning of the Act to the same extent as the foregoing indemnities from Middlesex to the several Underwriters, 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, Registration Statement or 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 Middlesex by any Underwriter through the Representatives expressly for use in any Preliminary Prospectus, the Registration Statement or 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 each 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) or Section 9 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 employed counsel reasonably satisfactory to the indemnified party 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. Expenses covered by the indemnification in this Section 8 shall be paid by the indemnifying party as they are incurred by the indemnified party. 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 Middlesex on the one hand and the Underwriters 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 Middlesex on the one hand and the Underwriters 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 Middlesex on the one hand and the Underwriters 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 Middlesex bears to the total underwriting discount and commissions received by the Underwriters, 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 Middlesex on the one hand or the Underwriters on the other hand and

the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

Middlesex and the Underwriters agree that it would not be just and equitable if contributions to this Section 8(d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) 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 provisions of the Agreement Among Underwriters shall govern contribution among Underwriters, (ii) no Underwriter (except as provided in the Agreement Among Underwriters) shall be required to contribute any amount in excess of the underwriting discounts and commissions applicable to the Shares purchased by such Underwriter, and (iii) no person guilty of fraudulent misrepresentation (within the meaning of Section 10(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations in this Section 8(d) to contribute are several in proportion to their individual underwriting obligations and not joint.

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 Underwriters and Middlesex, 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 any 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.

10. Effective Date of This Agreement and Termination Hereof.

(a) This Agreement shall become effective at 10:00 a.m., Philadelphia, Pennsylvania time, on the first business day following the Effective Date or at the time of the public offering by the Underwriters of the Shares, whichever is earlier, except that the provisions of Sections 6, 8, 9 and 10 hereof shall be effective upon execution hereof. 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 Underwriters for offering by dealers. The Representatives and Middlesex may prevent the provisions of this Agreement (other than those contained in Sections 6, 8, 9 and 10) hereof 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 Representatives shall have the right to terminate this Agreement at any time prior to the Closing Date or any Option Closing Date as provided in Sections 7 and 11 hereof or if any of the following have occurred: (i) 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 Middlesex or any of the Subsidiaries, whether or not arising in the ordinary course of business, that would, in the Representatives’ opinion, make the offering or delivery of the Shares impracticable; (ii) any outbreak 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 Representatives’ opinion, make the offering or delivery of the Shares impracticable; (iii) any suspension or limitation of trading generally in securities on the New York Stock Exchange, the American Stock Exchange, the Nasdaq National 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 Representatives’ opinion materially and adversely affects trading on such exchange or the over-the-counter market; (iv) 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 Representatives’ opinion materially and adversely affects or will materially or adversely affect the business or operations of Middlesex; (v) declaration of a banking moratorium by the United States, New York or Pennsylvania authorities; (vi) 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 Representatives’ opinion has a material adverse effect on the securities markets in the United States; or (vii) trading in any securities of Middlesex shall have been suspended or halted by NASD or the SEC.

(c) If the Representatives elect to prevent this Agreement from becoming effective or to terminate this Agreement as provided in this Section 10, the Representatives shall notify Middlesex hereof promptly by telephone, telex, telegraph, telegram or facsimile, confirmed by letter.

11. Default by an Underwriter.

(a) If any Underwriter or Underwriters shall default in its or their obligation to purchase Firm Shares or Optional Shares hereunder, and if the Firm Shares or Optional Shares with respect to which such default relates do not exceed in the aggregate 10% of the number of Firm Shares or Optional Shares, as the case may be, that all Underwriters have agreed to purchase on the relevant Closing Date or Option Closing Date, then the Representatives may make arrangements satisfactory to Middlesex for the purchase of such Firm Shares by other persons, including any of the Underwriters, but if no such arrangements are made by the relevant Closing Date or Option Closing Date, such Firm Shares or Optional Shares to which the default relates shall be purchased severally by the non-defaulting Underwriters in proportion to their respective commitments hereunder.

(b) If such default relates to more than 10% of the Firm Shares or Optional Shares, as the case may be, the Representatives may in their discretion arrange for another party or parties (including a non-defaulting Underwriter) to purchase such Firm Shares or Optional Shares to which such default relates, on the terms contained herein. In the event that the Representatives do not arrange for the purchase of the Firm Shares or Optional Shares to which a default relates as provided in this Section 11, this Agreement may be terminated by the Representatives or by Middlesex without liability on the part of the non-defaulting several

Underwriters (except as provided in Section 8 hereof) or Middlesex (except as provided in Sections 6 and 8 hereof); provided that if such default occurs with respect to Optional Shares after the Closing Date, this Agreement will not terminate as to the Firm Shares or any Optional Shares purchased prior to such termination. Nothing herein shall relieve a defaulting Underwriter of its liability, if any, to the other several Underwriters and to Middlesex for damages occasioned by its default hereunder.

(c) If the Firm Shares or Optional Shares to which the default relates are to be purchased by the non-defaulting Underwriters, or are to be purchased by another party or parties, the Representatives or Middlesex shall have the right to postpone the Closing Date or any Option Closing Date, as the case may be, for a reasonable period but not in any event exceeding seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus or in any other documents and arrangements, and Middlesex agrees to file promptly any amendment to the Registration Statement or supplement to the Prospectus that in the opinion of counsel for the Underwriters may thereby be made necessary. The terms “Underwriters” and “Underwriter” as used in this Agreement shall include any party substituted under this Section 11 with like effect as if it had originally been a party to this Agreement with respect to such Firm Shares and/or Optional Shares.

12. Information Furnished by Underwriters. The statement set forth on the last paragraph at the bottom of the cover page of the Prospectus regarding the terms of the Offering by the Underwriters, the legends below the table of contents on page of the Prospectus regarding stabilization and passive market making, the identity of the Underwriters set forth in the first paragraph under the heading “Underwriting,” the concession and reallowance figures appearing in the paragraph under the caption “Underwriting,” the representations with respect to stabilization activities in the paragraph under the heading “Underwriting,” the paragraph under the caption “Underwriting” regarding passive market making and discretionary authority in the paragraph under the heading “Underwriting” constitute the only written information furnished by reference or on behalf of any Underwriter referred to in Sections 1(b) and 8 hereof.

14. Parties. This Agreement shall inure solely to the benefit of, and shall be binding upon, the several Underwriters, Middlesex and the controlling persons, directors and officers thereof, and their respective successors, assigns, heirs and legal representatives, and no other

person shall have or be construed to have any legal or equitable right, remedy or claim under or in respect of or by virtue of this Agreement or any provision herein contained. The terms “successors” and “assigns” shall not include any purchaser of the Shares merely because of such purchase.

15. Definition of Business Day. For purposes of this Agreement, “business day” means any day on which the Nasdaq National Market is opened for trading.

Matters to be Covered in the Opinion of

Xxxxxx, XxXxxxxxxx & Xxxxxx, P.A.

Counsel for Middlesex

1. Middlesex is a corporation duly incorporated and validly existing in good standing under the laws of the State of New Jersey, with full corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Registration Statement and the Prospectus.

2. Each of the Subsidiaries is a corporation duly incorporated or limited liability company duly formed and validly existing in good standing under the laws of the state of its incorporation or formation with full power and authority as a corporation or limited liability company, as the case may be, to own, lease and operate its properties and to conduct its business as described in the Registration Statement and the Prospectus. All of the outstanding shares of capital stock of each of the Subsidiaries that are corporations have been duly authorized and validly issued, and are fully paid and nonassessable, and are owned by Middlesex directly, or indirectly through another Subsidiary of Middlesex, free and clear of any liens or other security interests. Middlesex, either directly or indirectly through another Subsidiary of Middlesex, is the sole member of each Subsidiary that is a limited liability company, and it owns its interest therein free and clear of any liens or other security interests. No provision of the operating agreement of any LLC Subsidiary or of the statutes pursuant to which they are formed requires the payment of additional capital to such LLC Subsidiary by the members thereof.

3. The Shares conform in all material respects to the description of the Common Stock in the Prospectus.

4. All shares of capital stock of Middlesex outstanding prior to the issuance of the Shares to be issued and sold by Middlesex hereunder are free of (a) any preemptive rights arising under Middlesex’s Certificate of Incorporation, as amended, or by the New Jersey Business Corporation Act or (b) to counsel’s knowledge, similar rights that entitle or will entitle any person to acquire any shares upon the issuance thereof by Middlesex.

5. Neither the execution, delivery or performance of the Underwriting Agreement, by Middlesex, compliance by Middlesex with the provisions of the Underwriting Agreement nor consummation by Middlesex of the transactions contemplated by the Underwriting Agreement (a) violates the provisions of the Certificate of Incorporation, as amended, or Bylaws of Middlesex, (b) violates the New Jersey Business Corporation Act or any present statute, rule or regulation promulgated by the United States that is applicable to Middlesex and to transactions of the type contemplated by the Underwriting Agreement, or (c) constitutes or will constitute a material breach of, or a default under, any material agreement or instrument known to counsel to which Middlesex or any Subsidiary is a party or by which Middlesex or any Subsidiary may be bound or which is filed as an exhibit to the Registration Statement.

B-1

6. The descriptions in the Registration Statement and the Prospectus of contracts and other documents are accurate in all material respects and fairly present the information required by the Act and the Regulations to be disclosed, and we do not know of any contracts or documents of a character required by the Act and the Regulations to be described in the Registration Statement or Prospectus or to be filed as exhibits to the Registration Statement that are not described and filed as required.

7. No consent, approval, authorization or other order of, or registration or filing with, any court, regulatory body, administrative agency or other governmental body, agency, or official is required on the part of Middlesex other than: (i) such as may be required under the Act and the Securities Exchange Act of 1934, as amended, (ii) such as may be required by the NASD or under state securities or Blue Sky laws of any jurisdiction applicable to the purchase and distribution of the Shares, as to which counsel need not express an opinion; and (iii) approval by the New Jersey Board of Public Utilities: for the valid issuance and sale of the Shares to the Underwriters as contemplated by the Underwriting Agreement.

8. The Registration Statement and the Prospectus, including the documents incorporated by reference therein, and each amendment or supplement to the Registration Statement and the Prospectus, as of their respective effective or issue dates (other than the financial statements and the notes thereto and schedules and other financial and statistical data found in or derived from the internal accounting and other financial records of Middlesex and its subsidiaries which is included therein or incorporated by reference or in exhibits to the Registration Statement, or which should have been included in the Registration Statement or exhibits thereto, as to which counsel need not express an opinion) comply as to form in all material respects with the requirements of the Act and the regulations thereunder. The eligibility requirements for the use of Form S-3 set forth in the General Instructions thereto have been satisfied.

9. Middlesex has the corporate power and authority to enter into the Underwriting Agreement and to perform its obligations thereunder. Middlesex has taken all corporate action necessary to authorize the execution, delivery and performance of the Underwriting Agreement. The Underwriting Agreement has been duly executed and delivered on behalf of Middlesex and constitutes the legal valid and binding obligation of Middlesex, enforceable against Middlesex in accordance with its terms, except to the extent enforceability may be limited by (i) the application of bankruptcy, reorganization, insolvency or other laws affecting creditors’ rights generally and (ii) equitable principles being applied at the discretion of a court before which any proceeding may be brought, and except as rights to indemnity and contribution thereunder may be limited by or unenforceable under federal or state securities laws.

10. The Shares to be issued and sold to the Underwriters by Middlesex pursuant to the Underwriting Agreement have been duly authorized and, when issued and delivered to the Underwriters against payment in full therefor in accordance with the terms thereof, such Shares will be validly issued, fully paid and nonassessable. The Shares are free of (a) any preemptive rights arising under Middlesex’s Certificate of Incorporation, as amended, or the New Jersey Business Corporation Act, or (b) to counsel’s knowledge similar rights that entitled or will entitle any person to acquire any of the Shares upon the sale of the Shares by Middlesex.

B-2

11. The descriptions in the Prospectus of statutes, regulations or legal or governmental proceedings, insofar as they purport to summarize certain of the provisions thereof, are accurate in all material respects and fairly present the information required to be presented by the Act and the rules and regulations thereunder.

12. Middlesex is not an “investment company” as defined in the Investment Company Act of 1940, as amended, and will not become an investment company as a result of the issuance and sale of the Shares, assuming that the net proceeds of the Shares are applied by Middlesex as disclosed in the Prospectus.

13. The statements in the Prospectus under the captions “Description of Capital Stock,” insofar as such statements constitute a summary of documents referred to therein or matters of law fairly summarize, in all material respects, the information required by the Act and the regulations thereunder with respect to such documents and matters.

14. To counsel’s knowledge, no material legal or governmental proceedings are pending or threatened against Middlesex or any of the Subsidiaries, or to which Middlesex or the Subsidiaries or any of their respective properties is subject, which are required to be described in the Registration Statement or the Prospectus that are not described as required.

15. Based upon communications with representatives of the Commission (i) the Registration Statement has become effective under the Act, (ii) no stop order suspending the effectiveness of the Registration Statement has been issued, and (iii) no proceedings for that purpose are pending before or contemplated by the Commission.

In rendering such opinion, counsel may rely, to the extent they deem such reliance proper, as to matters of fact upon certificates of officers of Middlesex and of government officials, provided that counsel shall state their belief that they and you are justified in relying thereon. Copies of all such certificates shall be furnished to you and your counsel on the Closing Date and the Option Closing Date, as the case may be. As to matters of law of all jurisdictions other than New Jersey, counsel may rely on the opinion of a firm licensed to practice law in such other jurisdiction reasonably acceptable to the Representatives.

In addition to the opinions set forth above, such counsel shall state that during the course of their participation in the preparation of the Registration Statement and the Prospectus and the amendments thereto, nothing has come to the attention of such counsel that has caused such counsel to believe or given such counsel reason to believe that the Registration Statement or the Prospectus or any amendment thereto (except for the financial statements and other financial and accounting information contained therein or omitted therefrom as to which no opinion need be expressed), at the date thereof, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading or that the Registration Statement or the Prospectus as of the date of the opinion (except as aforesaid), contains an untrue statement of a material fact or omits to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.
