(xxi) As of the date of the Company’s most recent certification pursuant to Section 302 of the Xxxxxxxx-Xxxxx Act of 2002 (the “Xxxxxxxx-Xxxxx Act”), the Company maintains systems of internal accounting controls and processes sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles; and (iii) assets are safeguarded from loss or unauthorized use. The Company evaluated the design and operation of their disclosure controls and procedures to determine whether they are effective in ensuring that the disclosure of required information is timely made in accordance with the Exchange Act and the rules and forms of the Commission. These evaluations were made under the supervision and with the participation of management, including the principal executive officer and principal financial officer of the Company, within the 45-day period prior to the filing of the most recent Quarterly Report on Form 10-Q. The principal executive officer and principal financial officer have concluded, based on their review, that the disclosure controls and procedures, as defined by Exchange Act Rules 13a-15(e) and 15(d)-14(c), are effective to ensure that information required to be disclosed by the Company in reports that it files under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in Commission rules and forms.

(xxiii) Deloitte and Touche LLP, who have certified certain financial statements of the Company and its subsidiaries, are independent registered public accountants with respect to the Company and its subsidiaries as required by the Securities Act.

(xxiv) The Indenture constitutes a direct and valid first mortgage lien, subject only to liens permitted by the Indenture (including “permitted liens” as defined in the Indenture) on that portion of the Trust Estate (as defined below) located in the State of New Hampshire, the State of Maine, or the State of Vermont and under existing New Hampshire, Maine, and Vermont law, as applicable, will, subject only to such liens permitted by the Indenture and subject to the provisions of the Federal Bankruptcy Code with respect to liens on property purporting to attach after the date of the commencement of proceedings thereunder, constitute a similar lien at the time of acquisition on all similar properties and assets of the Company acquired after the date hereof located within the State of New Hampshire, the State of Maine, or the State of Vermont and required by the Indenture to be subjected to the lien thereof, except real property in Maine or Vermont acquired after the date hereof until the filing of a supplemental indenture specifically subjecting such real property to such lien, and other than the properties and assets of the character excluded or excepted from the lien thereof (it being understood, however, that (i) under certain limited circumstances, the lien of the Indenture on real property in New Hampshire and personal property located thereon could be subordinated to a lien in favor of the State of New Hampshire pursuant to New Hampshire Revised Statutes Annotated 147-B:10-b, as amended, for expenses incurred in containing or removing hazardous waste or materials, and any necessary mitigation of damages with respect to hazardous waste or materials and (ii) under certain limited circumstances the lien of the Indenture on real property in Maine could be subordinated to a lien in favor of the State of Maine pursuant to Maine Revised Statutes Annotated, Title 38, Section 1371 providing for such a lien for costs of abatement, cleanup or mitigation of hazardous substances).

(xiv) the Indenture constitutes a direct and valid first mortgage lien, subject only to liens permitted by the Indenture (including “permitted liens” as defined in the Indenture) on that portion of the Trust Estate located in the State of New Hampshire, the State of Maine, or the State of Vermont and under existing New Hampshire, Maine, and Vermont law, as applicable, will, subject only to such liens permitted by the Indenture and subject to the provisions of the Federal Bankruptcy Code with respect to liens on property purporting to attach after the date of the commencement of proceedings thereunder, constitute a similar lien at the time of acquisition on all similar properties and assets of the Company acquired after the date hereof located within the State of New Hampshire, the State of Maine, or the State of Vermont and required by the Indenture to be subjected to the lien thereof, except real property in Maine or Vermont acquired after the date hereof until the filing of a supplemental indenture specifically subjecting such real property to such lien, and other than the properties and assets of the character excluded or excepted from the lien thereof (it being understood, however, that (i) under certain limited circumstances, the lien of the Indenture on real property in New Hampshire and personal property located thereon could be subordinated to a lien in favor of the State of New Hampshire pursuant to New Hampshire Revised Statutes Annotated 147-B:10-b, as amended, for expenses incurred in containing or removing hazardous waste or materials, and any necessary mitigation of damages with respect to hazardous waste or materials and (ii) under certain limited circumstances the lien of the Indenture on real property in Maine could be subordinated to a lien in favor of the State of Maine pursuant to Maine Revised Statutes Annotated, Title 38, Section 1371 providing for such a lien for costs of abatement, cleanup or mitigation of hazardous substances); no liens of the type referred to in the immediately preceding parenthetical have been recorded, or, to such counsel’s knowledge, threatened to be recorded, by the State of New Hampshire or the State of Maine, as applicable, against any of the Company’s New Hampshire or Maine properties; and the Indenture, and/or one or more appropriate certificates and/or financing statements with respect thereto, has been duly recorded or filed for recordation in all places within the State of New Hampshire, the State of Maine,

and the State of Vermont in which such recording or filing is required to protect and preserve the lien of the Indenture on said properties and assets of the Company located in New Hampshire, Maine, and Vermont which are presently subject thereto, and all New Hampshire, Maine, and Vermont taxes and fees required to be paid with respect to the execution and recording of the Indenture and the issuance of the Bonds have been paid (other than in connection with or in compliance with the provisions of the state securities or “Blue Sky” laws of any jurisdiction, as to which counsel need not express an opinion).

Such counsel shall also state that he has no reason to believe that (except for financial statements, schedules and other financial or statistical data contained or incorporated by reference in the Registration Statement, Pricing Disclosure Package or Prospectus, and except for that part of the Registration Statement that constitutes the Form T-1, as to all of which such counsel need not express any belief):

(A) any part of the Registration Statement, as of the Effective Date, contained any untrue statement of a material fact or omitted or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading,

(B) the Pricing Disclosure Package, as of the Applicable Time, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, or

(C) the Prospectus, as of its date and as of the date such opinion is delivered, contained or contains any untrue statement of a material fact or omitted or omits to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

Such counsel may state that his belief is based upon his participation in the preparation of the Registration Statement, the Pricing Disclosure Package and the Prospectus and documents incorporated therein by reference and review and discussion of the contents thereof, but are without independent check or verification, except as specified.

Utilities Service Company, Xxxxxx X. Xxxxxx, Assistant General Counsel of Northeast Utilities Service Company and Sulloway & Xxxxxx, P.L.L.C., counsel for the Company, each as addressed to him. Insofar as Xx. Xxxxxx’x opinion relates to matters governed by the law of the State of Maine he may rely on the opinion of even date therewith of Xxxxxxxx Xxxxxxx & XxxXxxxx, counsel for the Company, and for matters governed by the law of the State of Vermont, he may rely on the opinion of even date therewith of Xxxxxxx, Xxxxxx & Bent, counsel for the Company, each as addressed to him. Each of the foregoing opinions shall be addressed to or shall allow the Underwriters to rely on such opinion as if they were an addressee thereto.

The opinion(s) of Counsel described in Section 6(d) above shall be rendered to the Underwriters at the request of the Company and shall so state therein

(e) The Underwriters shall have received from Pillsbury Xxxxxxxx Xxxx Xxxxxxx LLP, special counsel for the Underwriters, an opinion dated the Closing Date and addressed to the Underwriters, with respect to such matters as the Representatives may reasonably require, and the Company shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters.

(f) The Underwriters shall have received on the date hereof and on the Closing Date, letters, the first dated the date hereof and the second dated the Closing Date, each in form and substance satisfactory to the Underwriters, from Deloitte & Touche LLP, containing statements and information of the type ordinarily included in accountants’ “comfort letters” to underwriters with respect to the financial statements and certain financial information contained in or incorporated by reference into the most recent Preliminary Prospectus, the Pricing Disclosure Package and the Prospectus.

If any of the conditions specified in this Section 6 shall not have been fulfilled when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be reasonably satisfactory in form and substance to the Representatives and counsel for the Underwriters, this Agreement and all obligations of the Underwriters hereunder may be canceled at, or at any time prior to, the Closing Date by the Representatives. Notice of such cancellation shall be given to the Company in writing or by telephone or facsimile confirmed in writing.

7. Covenants of the Company. In further consideration of the agreements of the Underwriters herein contained, the Company covenants with each Underwriter as follows:

(a) To furnish the Representatives, without charge, one (1) signed copy of the Registration Statement (including exhibits thereto) and, for delivery to each other Underwriter, a conformed copy of the Registration Statement (without exhibits thereto) and to furnish the Representatives in New York City, without charge, prior to 10:00 a.m. New York City time on the business day next succeeding the date of this Agreement and during the period mentioned in Section 7(e) below, as many copies of the Preliminary Prospectus, Prospectus, each Issuer Free Writing Prospectus, any documents incorporated by reference therein and any supplements and amendments thereto or to the Registration Statement as the Representatives may reasonably request.

(b) To prepare any Preliminary Prospectus and the Prospectus in a form approved by the Representatives and to file any such Preliminary Prospectus and the Prospectus pursuant to Rule 424(b) under the Securities Act not later than the Commission’s close of business on the second business day following the execution and delivery of this Agreement. If, at any time prior to the filing of the Prospectus pursuant to Rule 424(b), any event shall occur or condition exist as a result of which the Pricing Disclosure Package would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made or the circumstances then prevailing not misleading, the Company will (i) notify promptly the Representatives so that any use of the Pricing Disclosure Package may cease until it is amended or supplemented; (ii) amend or supplement the Pricing Disclosure Package to correct such statement or omission; and (iii) supply any amendment or supplement to the Underwriters in such quantities as the Representatives may reasonably request.

(c) If required by the Securities Act, to timely file with the Commission under the Securities Act each Issuer Free Writing Prospectus. The Company will prepare a final term sheet, containing solely a description of the Bonds, substantially in the form of Exhibit A to Schedule II hereto, in a form approved by the Representatives and to file such final term sheet pursuant to Rule 433 (d) under the Act within the time required by such Rule and to file all other material required to be filed by the Company with the Commission pursuant to Rule 433(d) under the Act.

(d) Before amending or supplementing the Registration Statement, any Preliminary Prospectus, the Pricing Disclosure Package or the Prospectus with respect to the Bonds, to furnish to the Representatives a copy of each such proposed amendment or supplement and not to file any such proposed amendment or supplement to which the Representatives reasonably objects.

(e) If, during such period after the first date of the public offering of the Bonds as in the opinion of counsel for the Underwriters the Prospectus is required by law to be delivered (including in such circumstances where such requirement can be satisfied pursuant to Rule 172) in connection with sales by an Underwriter or dealer, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances when the Prospectus is delivered to a purchaser, not misleading, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to the dealers (whose names and addresses the Representatives will furnish to the Company) to which Bonds may have been sold by the Representatives on behalf of the Underwriters and to any other dealers upon request, either amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances when the Prospectus is delivered to a purchaser, be misleading or so that the Prospectus, as amended or supplemented, will comply with law.

(f) To endeavor to qualify the Bonds for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Representatives shall reasonably request; provided, however, that the Company shall not be required to qualify as a foreign corporation or to file a consent to service of process or to file annual reports or to comply with any other requirements deemed by the Company in its reasonable judgment to be unduly burdensome.

(g) Not to make any offer relating to the Bonds that would constitute an Issuer Free Writing Prospectus without the prior written consent of the Representatives.

(h) To retain in accordance with the Rules and Regulations all Issuer Free Writing Prospectuses it uses or refers to; and if at any time after the date hereof any event shall have occurred as a result of which any Issuer Free Writing Prospectus, as then amended or supplemented, would conflict with the information in the Registration Statement, the most recent Preliminary Prospectus or the Prospectus or would include an untrue statement of a material fact or omit to state any material fact necessary in

order to make the statements therein, in the light of the circumstances under which they were made not misleading or, if for any other reason it shall be necessary to amend or supplement any Issuer Free Writing Prospectus, to notify the Representatives and, upon their request, to file such document and to prepare and furnish without charge to each Underwriter as many copies as the Representatives may from time to time reasonably request of an amended or supplemented Issuer Free Writing Prospectus that will correct such conflict, statement or omission or effect such compliance.

(i) To make generally available to the Company’s security holders, as soon as practicable, an earning statement (which need not be audited) covering a period of at least twelve months beginning after the “effective date of the registration statement” within the meaning of Rule 158 under the Securities Act, which earning statement shall be in such form, and be made generally available to security holders in such a manner, as to meet the requirements of the last paragraph of Section 11(a) of the Securities Act and Rule 158 under the Securities Act.

(j) During the period beginning on the date of this Agreement and continuing to and including the Closing Date, not to offer, sell, contract to sell or otherwise dispose of, directly or indirectly, any debt securities of the Company or warrants to purchase debt securities of the Company substantially similar to the Bonds (other than (i) the Bonds and (ii) commercial paper issued in the ordinary course of business), without the prior written consent of the Representatives.

(k) Whether or not the transactions contemplated in this Agreement are consummated or this Agreement is terminated, to pay or cause to be paid all expenses incident to the performance of its obligations under this Agreement, including: (i) the fees, disbursements and expenses of the Company’s counsel and the Company’s accountants in connection with the registration and delivery of the Bonds under the Securities Act and all other fees or expenses in connection with the preparation and filing of the Registration Statement, any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus and amendments and supplements to any of the foregoing, including all printing costs associated therewith, and the mailing and delivering of copies thereof to the Underwriters and dealers, in the quantities hereinabove specified, (ii) all costs and expenses related to the transfer and delivery of the Bonds to the Underwriters, including any transfer or other taxes payable thereon, (iii) the cost of printing or producing any Blue Sky or legal investment memorandum in connection with the offer and sale of the Bonds under state law and all expenses in connection with the qualification of the Bonds for offer and

sale under state law as provided in Section 7(f) hereof, including filing fees and the reasonable fees and disbursements of counsel for the Underwriters not to exceed $10,000 in connection with such qualification and in connection with the Blue Sky or legal investment memorandum, (iv) the fees and disbursements of the Company’s accountants and the Trustee and its counsel, (v) all filing fees and the reasonable fees and disbursements of counsel to the Underwriters incurred in connection with any review and qualification of the offering of the Bonds by the National Association of Securities Dealers, Inc., (vi) any fees charged by the rating agencies for the rating of the Bonds and (vii) all other costs and expenses incident to the performance of the obligations of the Company hereunder for which provision is not otherwise made in this Section. It is understood, however, that except as provided in this Section, Section 8 entitled “Indemnity and Contribution”, and clause (b) of Section 10 entitled “Defaulting Underwriters” below, the Underwriters will pay all of their costs and expenses, including fees and disbursements of their counsel (except as set forth in this Section 7(k)), and any advertising expenses connected with any offers they may make.

(l) The Company will comply with all applicable securities and other applicable laws, rules and regulations, including, without limitation, the Xxxxxxxx-Xxxxx Act, and will use its best efforts to cause the Company’s directors and officers, in their capacities as such, to comply with such laws, rules and regulations, including, without limitation, the provisions of the Xxxxxxxx-Xxxxx Act.

(m) The Company will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Bonds.

(n) If the supplemental indenture establishing the terms of the Bonds (the “Supplemental Indenture”) is not recorded prior to the Closing Date, then (1) within 10 days after the Closing Date, the Company shall deliver such Supplemental Indenture in recordable form to the appropriate real estate recording office in all jurisdictions specified in such Supplemental Indenture for recording and deliver to the office of the Secretary of State of the State of New Hampshire a UCC-1 financing statement relating to the Supplemental Indenture for filing in such office and (2) within 25 days after the Closing Date, the Company shall deliver to counsel to the Underwriters a certificate signed by an officer of the Company certifying that the actions required by the foregoing clause (1) have been taken. The Company shall further provide counsel to the

Underwriters, as soon as it is available, a copy of the related opinion of counsel contemplated by Section 5.8(b) of the Indenture. To the extent not covered in the opinion described in the previous sentence, the Company shall also provide counsel to the Underwriters, concurrently with the furnishing of such opinion, a list of the recording information for all such filings.

(o) The Company will pay the applicable Commission filing fees relating to the Bonds within the time required by Rule 456(b)(1) without regard to the proviso thereof.

(p) If immediately prior to the third anniversary (the “Renewal Deadline”) of the initial effective date of the Registration Statement, any of the Bonds remain unsold by the Underwriters, the Company will, prior to the Renewal Deadline, file, if it has not already done so and is eligible to do so, a new automatic shelf registration statement relating to the Bonds, in a form satisfactory to the Representatives. If the Company is no longer eligible to file an automatic shelf registration statement, the Company will prior to the Renewal Deadline, if it has not already done so, file a new shelf registration statement relating to the Bonds, in a form satisfactory to the Representatives, and will use its best efforts to cause such registration statement to be declared effective within 60 days after the Renewal Deadline. The Company will take all other action necessary or appropriate to permit the public offering and sale of the Bonds to continue as contemplated in the expired registration statement relating to the Bonds. References herein to the Registration Statement shall include such new automatic shelf registration statement or such new shelf registration statement, as the case may be.

(q) If at any time when Bonds remain unsold by the Underwriters the Company receives from the Commission a notice pursuant to Rule 401(g)(2) or otherwise ceases to be eligible to use the automatic shelf registration statement form, the Company will (i) promptly notify the Representatives, (ii) promptly file a new registration statement or post-effective amendment on the proper form relating to the Bonds, in a form satisfactory to the Representatives, (iii) use its best efforts to cause such registration statement or post-effective amendment to be declared effective and (iv) promptly notify the Representatives of such effectiveness. The Company will take all other action necessary or appropriate to permit the public offering and sale of the Bonds to continue as contemplated in the registration statement that was the subject of the Rule 401(g)(2) notice or for which the Company has otherwise become ineligible. References herein to the Registration Statement shall include such new registration statement or post-effective amendment, as the case may be.

8. Indemnity and Contribution. (a) The Company agrees to indemnify and hold harmless each Underwriter, its directors, officers and employees and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages and liabilities when and as incurred by them (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) that are based upon or arise out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Prospectus, the Pricing Disclosure Package, any Issuer Free Writing Prospectus or in any amendment or supplement thereto, or any “issuer information” (as defined in Rule 433) contained in any free writing prospectus, so long as the Company consented in writing to such free writing prospectus prior to its first use (“Permitted Issuer Information”) or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use therein, which information consists solely of the information specified in Section 8(g).

(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Company to such Underwriter, but only with reference to information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, any Preliminary Prospectus, the Prospectus, the Pricing Disclosure Package, any Issuer Free Writing Prospectus or in any amendments or supplements thereto, which information is limited to the information set forth in Section 8(g).

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to either Section 8(a) or 8(b), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing (but the omission so to notify the indemnifying party under this subsection shall not relieve it from any liability which it otherwise might have to an indemnified party otherwise than under this subsection) and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent

the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or (iii) the indemnifying party has not retained counsel within a reasonable period of time after the request by the indemnified party to do so. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Representatives, in the case of parties indemnified pursuant to Section 8(a) above, and by the Company, in the case of parties indemnified pursuant to Section 8(b) above. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding 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 claims that are the subject matter of such proceeding.

(d) To the extent the indemnification provided for in Section 8(a) or 8(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Bonds or (ii) if the allocation provided by clause 8(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 8(d)(i) above but also the relative fault of each indemnifying party on the one hand and each indemnified party on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or

liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the offering of the Bonds shall be deemed to be in the same respective proportions as the net proceeds from the offering of such Bonds (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus Supplement, bear to the aggregate public offering price of the Bonds. The relative fault of each indemnifying party on the one hand and each indemnified party on the other hand 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 such indemnifying party or by such indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective principal amounts of Bonds they have purchased hereunder, and not joint.

(e) The Company and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 8 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 in Section 8(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, 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, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Bonds underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(f) The indemnity and contribution provisions contained in this Section 8 and the representations, warranties and other statements of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter or the Company, its officers or directors or any person controlling the Company and (iii) acceptance of and payment for any of the Bonds.

(g) The Underwriters severally confirm and the Company acknowledges and agrees that the statements regarding (i) delivery of the Bonds by the Underwriters set forth in the last paragraph of text on the cover page, (ii) in the third and fifth paragraphs of text under the caption “Underwriting” appearing on page S-22 and (iii) in the third sentence of the fourth paragraph of text under the caption “Underwriting” appearing on page S-22 of the most recent Preliminary Prospectus are correct and constitute the only information concerning such Underwriter furnished in writing to the Company by or on behalf of the Underwriters specifically for inclusion in the Registration Statement, any Preliminary Prospectus, the Prospectus, the Pricing Disclosure Package, any Issuer Free Writing Prospectus or in any amendment or supplement thereto.

9. Termination. This Agreement shall be subject to termination by notice given by the Representatives to the Company, if (a) after the execution and delivery of this Agreement and on or prior to the Closing Date (i) trading generally shall have been suspended or materially limited on or by, as the case may be, any of the New York Stock Exchange, the American Stock Exchange, the Financial Industry Regulatory Authority, the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade or there shall have been established by any of such exchanges or by the Commission or by any federal or state agency or by the decision of any court, any general limitation on prices for such trading or any general restrictions on the distribution of securities, (ii) trading of any securities of the Company or Northeast Utilities shall have been suspended on any exchange or in any over-the-counter market, (iii) a general moratorium on commercial banking activities in New York shall have been declared by either Federal or New York State authorities, (iv) there shall have occurred any (A) outbreak of hostilities affecting the United States, or (B) other national or international calamity or crisis, or any material adverse change in financial, political or economic conditions affecting the United States, including, but not limited to, an escalation of hostilities that existed prior to the date of this Agreement, or (v) there shall have occurred any material disruption in commercial banking securities settlement or clearance services and (b) in the case of any of the events specified in clauses 9(a)(i) through 9(a)(v), such event, singly or together with any other such event, makes it impracticable or inadvisable, in the judgment of the Representatives, to proceed with the offer, sale or delivery of the Bonds on the terms and in the manner contemplated in the most recent Preliminary Prospectus or the Prospectus.

10. Defaulting Underwriters.(a) If, on the Closing Date, any one or more of the Underwriters shall fail or refuse to purchase the Bonds set forth opposite the name of such Underwriter or Underwriters in Schedule I hereto that it has or

they have agreed to purchase hereunder on such date, and the aggregate amount of such Bonds which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate amount of the Bonds of such Underwriter or Underwriters to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the amount of such Bonds set forth opposite their respective names in Schedule I hereto bears to the aggregate amount of such Bonds set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Representatives may specify, to purchase the Bonds which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the amount of the Bonds that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 10 by an amount in excess of one-ninth of such amount of such Bonds without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase such Bonds and the aggregate amount of such Bonds with respect to which such default occurs is more than one-tenth of the aggregate amount of such Bonds to be purchased on such date, and arrangements satisfactory to the Representatives and the Company for the purchase of such Bonds are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company. In any such case either the Representatives or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement and in the Prospectus or in any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

(b) If this Agreement shall be terminated by the Underwriters because any condition to the obligation of the Underwriters set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 9 hereof or because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, the Company will reimburse the Underwriters for all out of pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by the Underwriters in connection with this Agreement or the offering contemplated hereunder.

11. No Fiduciary Duty. The Company acknowledges and agrees that in connection with this offering, sale of the Bonds or any other services the Underwriters may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters: (i) no fiduciary or agency relationship between the Company, on the one hand, and the Underwriters, on the other,

exists; (ii) the Underwriters are not acting as advisors, expert or otherwise, to the Company, including, without limitation, with respect to the determination of the public offering price of the Bonds, and such relationship between the Company, on the one hand, and the Underwriters, on the other, is entirely and solely commercial and based on arms-length negotiations; (iii) any duties and obligations that the Underwriters may have to the Company shall be limited to those duties and obligations specifically stated herein; and (iv) the Underwriters and their respective affiliates may have interests that differ from those of the Company. The Company hereby waives any claims that the Company may have against the Underwriters with respect to any breach of fiduciary duty in connection with this offering.

12. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Bonds. The provisions of Sections 8 and 10(b) hereof shall survive the termination or cancellation of this Agreement

13. Notices.
