CONDITIONS TO THE OBLIGATIONS OF THE INITIAL PURCHASERS. The obligations of the Initial Purchasers to purchase the Securities shall be subject to the accuracy of the representations and warranties on the part of the Company contained herein at the Execution Time, the Closing Date and any settlement date pursuant to Section 3 hereof, to the accuracy of the statements of the Company made in any certificates pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions: (a) The Company shall have requested and caused Day, Berry & Howard LLP, counsel for the Company, and Jeffrey C. Miller, Assistant General Counsel of Northeast Utilities Service Company, to furnish to the Representative their opinions, dated the Closing Date and addressed to the Representative, in form and substance reasonably satisfactory to the Representative and its counsel. In rendering such opinions, such counsels may rely (A) as to matters involving the application of laws of any jurisdiction other than Connecticut, the State of New York or Federal laws of the United States, to the extent they deem proper and specified in such opinion, upon the opinion of other counsel of good standing whom they believe to be reliable and who are satisfactory to counsel for the Initial Purchasers; and (B) as to matters of fact, to the extent they deem proper, on certificates of responsible officers of the Company and public officials. (b) The Representative shall have received from Milbank, Tweed, Hadley & McCloy LLP counsel for the Initial Purchasers, such opinion or opinions, dated the Closing Date and addressed to the Representative, with respect to the issuance and sale of the Securities, the Indenture, the Registration Rights Agreement, the Final Memorandum (as amended or supplemented at the Closing Date) and other related matters as the Representative may reasonably require, and the Company shall have furnished to such counsel such documents as they reasonably request for the purpose of enabling them to pass upon such matters. (c) The Company shall have furnished to the Representative a certificate of the Company, signed by the President and the principal financial or accounting officer of the Company or comparable officers of Northeast Utilities Service Company as agents of the Company, dated the Closing Date, to the effect that the signers of such certificate have carefully examined the Final Memorandum, any amendment or supplement to the Final Memorandum and this Agreement and that: 13 <Page> (i) the representations and warranties of the Company in this Agreement are true and correct in all material respects on and as of the Closing Date with the same effect as if made on the Closing Date; (ii) the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied hereunder at or prior to the Closing Date; and (iii) since the date of the most recent financial statements included in the Final Memorandum (exclusive of any amendment or supplement thereto), there has been no material adverse change in the condition (financial or otherwise), prospects, earnings, business or properties of the Company whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated by the Final Memorandum (exclusive of any amendment or supplement thereto). (d) At the Execution Time and at the Closing Date, the Company shall have requested and caused Arthur Andersen LLP to furnish to the Representative letters, dated respectively as of the Execution Time and as of the Closing Date, in form and substance satisfactory to the Representative, confirming that they are independent accountants within the meaning of the Act and the Exchange Act and the applicable rules and regulations thereunder, that they have performed a review of the unaudited interim financial information of the Company for the six-month period ended June 30, 2001 and as at June 30, 2001, in accordance with the Statement on Auditing Standards No. 71, and stating in effect that: (i) in their opinion the audited financial statements and financial statement schedules included in the Final Memorandum and reported on by them comply as to form in all material respects with the applicable accounting requirements of the Exchange Act and the related published rules and regulations thereunder; (ii) on the basis of a reading of the latest unaudited financial statements made available by the Company; their limited review in accordance with the standards established under Statement on Auditing Standards No. 71, of the unaudited interim financial information for the six-month period ended June 30, 2001, and as at June 30, 2001, as indicated in their report included in the Final Memorandum; carrying out certain specified procedures (but not an examination in accordance with generally accepted auditing standards) which would not necessarily reveal matters of significance with respect to the comments set forth in such letter; a reading of the minutes of the meetings of the stockholders and Board of Directors of the Company; and inquiries of certain officials of the Company who have responsibility for financial and accounting matters of the Company as to transactions and events subsequent to December 31, 2000, nothing came to their attention which caused them to believe that: (1) any unaudited financial statements included in the Final Memorandum do not comply in form in all material respects with applicable accounting requirements and with the published rules and regulations of the 14 <Page> Commission with respect to financial statements included in quarterly reports on Form 10-Q under the Exchange Act; and said unaudited financial statements are not in conformity with generally accepted accounting principles applied on a basis substantially consistent with that of the audited financial statements included in the Final Memorandum; or (2) with respect to the period subsequent to December 31, 2000, there were any changes, at a specified date not more than five days prior to the date of the letter, in the long-term debt of the Company or capital stock of the Company or decreases in the stockholders' equity of the Company as compared with the amounts shown on the December 31, 2000 balance sheet included in the Final Memorandum, or for the period from January 1, 2001 to such specified date there were any decreases, as compared with the corresponding period in the preceding year, in net revenues or income before income taxes or in total net income or operating income of the Company, except in all instances for changes or decreases set forth in such letter, in which case the letter shall be accompanied by an explanation by the Company as to the significance thereof unless said explanation is not deemed necessary by the Representative; (iii) they have performed certain other specified procedures as a result of which they determined that certain information of an accounting, financial or statistical nature (which is limited to accounting, financial or statistical information derived from the general accounting records of the Company) set forth in the Final Memorandum, including the information set forth under the caption "Our Affiliates" in the Final Memorandum and the information included in "Management's Discussion and Analysis of Financial Condition and Results of Operations" included in the Final Memorandum, agrees with the accounting records of the Company, excluding any questions of legal interpretation. References to the Final Memorandum in this Section 6(d) include any amendment or supplement thereto at the date of the letter. (e) Subsequent to the Execution Time or, if earlier, the dates as of which information is given in the Final Memorandum, there shall not have been (i) any change or decrease specified in the letter or letters referred to in paragraph (d) of this Section 6; or (ii) any change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), prospects, earnings, business or properties of the Company whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Final Memorandum (exclusive of any amendment or supplement thereto), the effect of which, in any case referred to in clause (i) or (ii) above, is, in the sole judgment of the Representative, so material and adverse as to make it impractical or inadvisable to market the Securities as contemplated by the Final Memorandum (exclusive of any amendment or supplement thereto). (f) The Initial Purchasers shall have received on and as of the Closing Date a certificate of an authorized officer of the Company, as to and attaching (i) resolutions of the 15 <Page> Company's board of directors authorizing and approving the transactions contemplated by the Transaction Documents to which it is a party, (ii) the Company's organizational documents and (iii) the incumbency of the officers of the Company or Northeast Utilities Service Company as agents of the Company executing the Transaction Documents to which the Company is a party. (g) The Initial Purchasers shall have received on and as of the Closing Date a certificate of an authorized officer of the Trustee, as to and attaching (i) resolutions of the Trustee's board of directors authorizing and approving the transactions contemplated by the Transaction Documents, (ii) the Trustee's organizational documents and (iii) certified copies of powers of attorney or signature circulars, if any, pursuant to which officers of the Trustee shall execute the Transaction Documents. (h) Each Transaction Document (other than the Initial Select Power Sales Agreement) shall have been duly executed by each of the parties thereto on or prior to the Closing Date, shall be in form and substance satisfactory to the Initial Purchasers and shall have been delivered to the Initial Purchasers. A copy of the Initial Select Power Sales Agreement shall have been delivered to the Initial Purchasers. (i) The Initial Purchasers shall have received on and as of the Closing Date a certificate of an authorized representative of the Trustee to the effect that the Debt Service Reserve Account has been established. (j) The Securities shall be eligible for clearance and settlement through The Depository Trust Company. (k) Moody's Investors Service Inc. ("Moody's"), Fitch IBCA Inc. ("Fitch") and Standard & Poor's Ratings Services Inc. ("S&P") shall have rated the Securities at least Baa3, BBB- and BBB-, respectively. Subsequent to the execution and delivery of this Agreement and prior to the Closing Date (i) no downgrading shall have occurred in the rating accorded the Securities by Moody's, Fitch, S&P or any other "nationally recognized statistical rating organization", as such term is defined by the Commission for purposes of Rule 436(g)(2) of the rules and regulations of the Commission under the Securities Act and (ii) no such organization shall have publicly announced that it has under surveillance or review (other than an announcement with positive implications of a possible upgrading), its rating of the Securities. (l) S&W Consultants, Inc. shall have (i) consented to the inclusion of its report in the Preliminary Memorandum, the Final Memorandum and any registration statement filed in accordance with the Registration Rights Agreement and (ii) provided a letter, dated the Closing Date, confirming its report and the conclusions therein as of the Closing Date. (m) PA Consulting, Inc. shall have (i) consented to the inclusion of its report in the Preliminary Memorandum, the Final Memorandum and any registration statement filed in accordance with the Registration Rights Agreement and (ii) provided a letter, dated the Closing Date, confirming its report and the conclusions therein as of the Closing Date. (n) Prior to the Closing Date, the Initial Purchasers shall have received such further information, certificates and documents as the Representative may reasonably request. 16 <Page> If any of the conditions specified in this Section 6 shall not have been fulfilled in all material respects 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 in all material respects reasonably satisfactory in form and substance to the Representative and counsel for the Initial Purchasers, this Agreement and all obligations of the Initial Purchasers hereunder may be canceled at, or at any time prior to, the Closing Date by the Representative. Notice of such cancellation shall be given to the Company in writing or by telephone or facsimile confirmed in writing. The documents required to be delivered by this Section 6 will be delivered at the office of counsel for the Initial Purchasers, at 1 Chase Manhattan Plaza, New York, New York, 10005, on the Closing Date. 7. REIMBURSEMENT OF EXPENSES. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Initial Purchasers set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 10 hereof or because of any refusal, inability or failure on the part of the Company to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Initial Purchasers, the Company will reimburse the Initial Purchasers severally through Salomon Smith Barney on demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities. 8. INDEMNIFICATION AND CONTRIBUTION. (a) The Company agrees to indemnify and hold harmless each Initial Purchaser, the directors, officers, employees and agents of each Initial Purchaser and each person who controls any Initial Purchaser within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Memorandum, the Final Memorandum (or in any supplement or amendment thereto) or any information provided by the Company to any holder or prospective purchaser of Securities pursuant to Section 5(h), or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; PROVIDED, HOWEVER, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made in the Preliminary Memorandum or the Final Memorandum, or in any amendment thereof or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Initial Purchasers through the Representative specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Company may otherwise have. 17 <Page> (b) Each Initial Purchaser severally, and not jointly, agrees to indemnify and hold harmless the Company, each of its directors, each of its officers, and each person who controls the Company within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Initial Purchaser, but only with reference to written information relating to such Initial Purchaser furnished to the Company by or on behalf of such Initial Purchaser through the Representative specifically for inclusion in the Preliminary Memorandum or the Final Memorandum (or in any amendment or supplement thereto). This indemnity agreement will be in addition to any liability which any Initial Purchaser may otherwise have. The Company acknowledges that the statements set forth in the last paragraph of the cover page regarding delivery of the Securities, the legend in block capital letters and the related disclosure on page [___] concerning stabilization, syndicate covering transactions and penalty bids and, under the heading "Plan of Distribution", (i) the sentences related to concessions and reallowances; and (ii) the paragraph related to stabilization, syndicate covering transactions and penalty bids in the Preliminary Memorandum and the Final Memorandum, constitute the only information furnished in writing by or on behalf of the Initial Purchasers for inclusion in the Preliminary Memorandum or the Final Memorandum (or in any amendment or supplement thereto). (c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action against the indemnified party and such failure results in the forfeiture by the indemnifying party of any substantial right or defense; and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party's choice at the indemnifying party's expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); PROVIDED, HOWEVER, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party's election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or 18 <Page> proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding. (d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the Initial Purchasers agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively "Losses") to which the Company and one or more of the Initial Purchasers may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Initial Purchasers on the other from the offering of the Securities; PROVIDED, HOWEVER, that in no case shall any Initial Purchaser (except as may be provided in any agreement among the Initial Purchasers relating to the offering of the Securities) be responsible for any amount in excess of the purchase discount or commission applicable to the Securities purchased by such Initial Purchaser hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company and the Initial Purchasers shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and of the Initial Purchasers on the other in connection with the statements or omissions which resulted in such Losses, as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Initial Purchasers shall be deemed to be equal to the total purchase discounts and commissions in each case set forth on the cover of the Final Memorandum. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement or the omission or alleged omission to state a material fact relates to information provided by the Company on the one hand or the Initial Purchasers on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Initial Purchasers agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls an Initial Purchaser within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of an Initial Purchaser shall have the same rights to contribution as such Initial Purchaser, and each person who controls the Company within the meaning of either the Act or the Exchange Act and each officer and director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d). 9. DEFAULT BY AN INITIAL PURCHASER. If any one or more Initial Purchasers shall fail to purchase and pay for any of the Securities agreed to be purchased by such Initial Purchaser hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Initial Purchasers shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Securities set 19 <Page> forth opposite their names in Schedule I hereto bears to the aggregate principal amount of Securities set forth opposite the names of all the remaining Initial Purchasers) the Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase; PROVIDED, HOWEVER, that in the event that the aggregate principal amount of Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule I hereto, the remaining Initial Purchasers shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Initial Purchasers do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Initial Purchaser or the Company. In the event of a default by any Initial Purchaser as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representative shall determine in order that the required changes in the Final Memorandum or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Initial Purchaser of its liability, if any, to the Company or any nondefaulting Initial Purchaser for damages occasioned by its default hereunder. 10. TERMINATION. This Agreement shall be subject to termination in the absolute discretion of the Representative, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such time (i) trading in securities generally on the New York Stock Exchange shall have been suspended or limited or minimum prices shall have been established on such exchange; (ii) a banking moratorium shall have been declared either by Federal or New York State authorities; or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representative, impracticable or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Final Memorandum (exclusive of any amendment or supplement thereto). 11. REPRESENTATIONS AND INDEMNITIES TO SURVIVE. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the Initial Purchasers 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 the Initial Purchasers or the Company or any of the officers, directors or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement. 12. NOTICES.

JURISDICTION. The Company agrees that any suit, action or proceeding against the Company brought by any Initial Purchaser, the directors, officers, employees and agents of any Initial Purchaser, or by any person who controls any Initial Purchaser, arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in any State or Federal court in The City of New York, New York, and waives any objection which it may now or hereafter have to the laying of venue of any such proceeding, and irrevocably submits to the nonexclusive jurisdiction of such courts in any suit, action or proceeding. Notwithstanding the foregoing, any action arising out of or based upon this Agreement may be instituted by any Initial Purchaser, the directors, officers, employees and agents of any Initial Purchaser, or by any person who controls any Initial Purchaser, in any court of competent jurisdiction in Connecticut. 15. APPLICABLE LAW. This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York. 16. COUNTERPARTS.
