(a) The Company agrees to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages, liabilities and judgments (including, without limitation, any legal or other expenses incurred in connection with investigating or defending any matter, including any action, that could give rise to any such losses, claims, damages, liabilities or judgments) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), the Prospectus (or any amendment or supplement thereto) or any preliminary prospectus, or caused by 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, liabilities or judgments are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to the Underwriters furnished in writing to the Company by or on behalf of the Underwriters expressly for use therein; PROVIDED, HOWEVER, that the foregoing indemnity agreement with respect to any preliminary prospectus shall not inure to the benefit of any Underwriter who failed to deliver a Prospectus (as then amended or supplemented, provided by the Company to the several Underwriters in the requisite quantity and on a timely basis to permit proper delivery on or prior to the Closing Date) to the person asserting any losses, claims, damages and liabilities and judgments caused by any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus, or caused by 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, if such material misstatement or omission or alleged -11- material misstatement or omission was cured in such Prospectus and such Prospectus was required by law to be delivered at or prior to the written confirmation of sale to such person. (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 Section 15 of the Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Company to each Underwriter but only with reference to information relating to the Underwriters furnished in writing to the Company by or on behalf of the Underwriters expressly for use in the Registration Statement (or any amendment thereto), the Prospectus (or any amendment or supplement thereto) or any preliminary prospectus. (c) In case any action shall be commenced involving any person in respect of which indemnity may be sought pursuant to Section 7(a) or 7(b) (the "indemnified party"), the indemnified party shall promptly notify the person against whom such indemnity may be sought (the "indemnifying party") in writing and the indemnifying party shall assume the defense of such action, including the employment of counsel reasonably satisfactory to the indemnified party and the payment of all fees and expenses of such counsel, as incurred (except that in the case of any action in respect of which indemnity may be sought pursuant to both Sections 7(a) and 7(b), the Underwriter shall not be required to assume the defense of such action pursuant to this Section 7(c), but may employ separate counsel and participate in the defense thereof, but the fees and expenses of such counsel, except as provided below, shall be at the expense of such Underwriter). Any indemnified party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the indemnified party unless (i) the employment of such counsel shall have been specifically authorized in writing by the indemnifying party, (ii) the indemnifying party shall have failed to assume the defense of such action or employ counsel reasonably satisfactory to the indemnified party or (iii) the named parties to any such action (including any impleaded parties) include both the indemnified party and the indemnifying party, and the indemnified party shall have been advised by such counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party (in which case the indemnifying party shall not have the right to assume the defense of such action on behalf of the indemnified party). In any such case, the indemnifying party shall not, in connection with any one action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all indemnified parties and all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by DLJ, in the case of parties indemnified pursuant to Section 7(a), and by the Company, in the case of parties indemnified pursuant to Section 7(b). The indemnifying party shall not be liable for any settlement of any such action effected without its written consent but the indemnifying party shall indemnify and hold harmless the indemnified party from and against any and all losses, claims, damages, liabilities and judgments by reason of any settlement of any action effected with the indemnifying party's written consent. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement or compromise of, or consent to the entry of -12- judgment with respect to, any pending or threatened action in respect of which the indemnified party is or could have been a party and indemnity or contribution may be or could have been sought hereunder by the indemnified party, unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability on claims that are or could have been the subject matter of such action and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of the indemnified party. (d) To the extent the indemnification provided for in this Section 7 is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages, liabilities or judgments referred to therein, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities and judgments (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 Notes or (ii) if the allocation provided by clause 7(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 7(d)(i) above but also the relative fault of the Company on the one hand and the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or judgments, 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 shall be deemed to be in the same proportion as the total net proceeds from the offering (after deducting underwriting discounts and commissions but before deducting expenses) received by the Company, and the total underwriting discounts and commissions received by the Underwriters, bear to the total price to the public of the Notes, in each case as set forth in the table on the cover page of the Prospectus. The relative fault of the Company on the one hand and the Underwriters 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 the Company or the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7(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 which does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or judgments referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such indemnified party in connection with investigating or defending any matter, including any action, that could have given rise to such losses, claims, damages, liabilities or judgments. Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Notes underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise -13- 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations to contribute pursuant to this Section 7(d) are several in proportion to the respective principal amount of Notes purchased by each of the Underwriters hereunder and not joint. (e) The remedies provided for in this Section 7 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. 8. CONDITIONS OF UNDERWRITERS' OBLIGATIONS. The several obligations of the Underwriters to purchase the Notes under this Agreement are subject to the satisfaction of each of the following conditions: (a) All the representations and warranties of the Company contained in this Agreement shall be true and correct on the Closing Date with the same force and effect as if made on and as of the Closing Date. (b) The Registration Statement shall have become effective not later than 5:00 p.m. (and, in the case of a Registration Statement filed under Rule 462(b) of the Act, not later than 10:00 p.m.), New York City time, on the date of this Agreement or at such later date and time as the Underwriters may approve in writing, and on the Closing Date no stop order suspending the effectiveness of the Registration Statement shall have been issued and no proceedings for that purpose shall have been commenced or shall be pending before or, to the Company's knowledge, contemplated by the Commission. (c) On or after the date hereof, (i) no "nationally recognized statistical rating organization" as such term is defined for purposes of Rule 436(g)(2) under the Act shall have publicly announced that it is considering (A) the downgrading, suspension or withdrawal of, or any review for a possible change that does not indicate the direction of the possible change in, any rating assigned to the Company or any securities of the Company or (B) any change in the outlook for any rating of the Company or any securities of the Company, and (ii) no such rating organization shall have given notice that it has assigned (or publicly announced that it is considering assigning) a lower rating to the Notes than that on which the Notes were marketed. (d) Since the respective dates as of which information is given in the Prospectus other than as set forth in the Prospectus (exclusive of any amendments or supplements thereto subsequent to the date of this Agreement), (i) there shall not have occurred any material adverse change or any development involving a prospective material adverse change in the business, financial condition or results of operations of the Company and its subsidiaries, taken as a whole, (ii) there shall not have been any change or any development involving a prospective material adverse change in the capital stock or in the long-term debt of the Company or any of its subsidiaries and (iii) neither the Company nor any of its subsidiaries shall have incurred any liability or obligation, direct or contingent, not in -14- the ordinary course of business, which is material and adverse and makes it impracticable to market the Notes on the terms and in the manner contemplated in the Prospectus. (e) The Underwriters shall have received on the Closing Date a certificate dated the Closing Date, signed by William E. Davis and William F. Edwards, in their capacities as the Chief Executive Officer and Chief Financial Officer of the Company, confirming the matters set forth in Sections 8(a), 8(b), 8(d) and 8(i) and that the Company has complied with all of the agreements and satisfied all of the conditions herein contained and required to be complied with or satisfied by the Company on or prior to the Closing Date. (f) The Underwriters shall have received on the Closing Date an opinion (satisfactory to the Underwriters and counsel for the Underwriters), dated the Closing Date, of Sullivan & Cromwell, counsel for the Company, Swidler & Berlin, regulatory counsel for the Company, Bryan Cave LLP, special tax counsel for the Company, and Paul Kaleta, Esq., the Company's Vice President-Law & General Counsel, substantially in the form of Exhibits 1A, 1B, 1C and 1D hereto, respectively. (g) The Underwriters shall have received on the Closing Date an opinion, dated the Closing Date, of Sidley & Austin, counsel for the Underwriters, substantially in the form of Exhibit 2 hereto. (h) The Underwriters shall have received a letter dated on and as of the Closing Date, in form and substance satisfactory to the Underwriters, from Price Waterhouse LLP, independent public accountants, with respect to the financial statements and certain financial information contained in the Registration Statement and the Prospectus in the form and substance of the letter delivered to the Underwriters by Price Waterhouse LLP on the date of this Agreement. (i) The New York Public Service Commission (the "PSC") shall have issued a written order or orders (the "PSC Orders") approving the Company's PowerChoice Settlement Agreement the "PowerChoice Agreement"), including the issuance by the Company of the Notes pursuant to the Master Restructuring Agreement dated July 9, 1997, as amended (the "MRA"); the PSC Orders shall remain in full force and effect; the PSC shall not have publicly indicated its intention to modify, amend or otherwise change the PSC Orders in any material respect; no party or entity with legal standing shall have entered a notice of appeal, or otherwise publicly indicated it intention to appeal, the PSC Orders; no judicial or administrative proceeding shall have been instituted that challenges the validity of, or otherwise seeks to modify, amend, stay or enjoin the effectiveness of, the PSC Orders if (with respect to any of the events in this and the two immediately preceding clauses), in the reasonable judgment of the Underwriters, such event makes it impracticable to market the Notes on the terms and in the manner contemplated in the Prospectus; and all conditions precedent to the effectiveness of the PowerChoice Agreement and the MRA shall have been satisfied and the transactions contemplated by MRA shall have closed (or shall close concurrently with the Closing hereunder). (j) The Underwriters shall have received a counterpart, conformed as executed, of the -15- Indenture which shall have been entered into by the Company and the Trustee. (k) The Company shall not have failed on or prior to the Closing Date to perform or comply in any material respect with any of the agreements herein contained and required hereunder to be performed or complied with by the Company on or prior to the Closing Date. 9. EFFECTIVENESS OF AGREEMENT AND TERMINATION. This Agreement shall become effective upon its execution by and of the parties hereto. This Agreement may be terminated at any time on or prior to the Closing Date by the Underwriters by written notice to the Company if any of the following has occurred: (i) since the respective dates as of which information is given in the Registration Statement and the Prospectus, any material adverse change or development involving a prospective material adverse change in the business, financial condition or results of operations of the Company and its subsidiaries, taken as a whole, whether or not arising in the ordinary course of business, which would, in the Underwriters' good faith judgment, make it impracticable to market the Notes on the terms and in the manner contemplated in the Prospectus, (ii) any outbreak or escalation of hostilities involving the United States or other national or international calamity or crisis involving the United States or change in economic conditions or in the financial markets of the United States that, in the Underwriters' good faith judgment, is material and adverse and would, in the Underwriters' good faith judgment, make it impracticable to market the Notes on the terms and in the manner contemplated in the Prospectus, (iii) the suspension or material limitation of trading in securities or other instruments on the New York Stock Exchange or limitation on prices for securities or other instruments generally on such exchange, or (iv) the declaration of a banking moratorium by either federal or New York State authorities. If on the Closing Date any one or more of the Underwriters shall fail or refuse to purchase the Notes which it or they have agreed to purchase hereunder on such date and the aggregate principal amount of Notes which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate principal amount of Notes to be purchased on such date by all Underwriters, each non-defaulting Underwriter shall be obligated severally, in the proportion which the principal amount of Notes set forth opposite its name in Schedule I bears to the aggregate principal amount of Notes which all the non-defaulting Underwriters have agreed to purchase, or in such other proportion as the Underwriters may specify, to purchase the Notes which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; PROVIDED that in no event shall the aggregate principal amount of Notes which any Underwriter has agreed to purchase pursuant to Section 2 hereof be increased pursuant to this Section 9 by an amount in excess of one-ninth of such principal amount of Notes without the written consent of such Underwriter. If on the Closing Date any Underwriter or Underwriters shall fail or refuse to purchase Notes and the aggregate principal amount of Notes with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Notes to be purchased on such date by all Underwriters and arrangements satisfactory to the Underwriters and -16- the Company for purchase of such Notes are not made within 48 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter and the Company. In any such case which does not result in termination of this Agreement, either the Underwriters 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 the Prospectus or 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 any such Underwriter under this Agreement. 10. MISCELLANEOUS.

The respective indemnities, contribution agreements, representations, warranties and other statements of the Company, its officers and directors and of the Underwriters set forth in or made pursuant to this Agreement shall remain operative and in full force and effect, and will survive delivery of and payment for the Notes, regardless of (i) any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter or any person controlling any Underwriter, the Company, the officers or directors of the Company or any person controlling the Company, (ii) acceptance of the Notes and payment for them hereunder and (iii) termination of this Agreement. If this Agreement shall be terminated by the Underwriters because of any failure or refusal on the part of the Company to comply with any of the terms or to fulfill any of the conditions of this Agreement, the Company agrees to reimburse the Underwriters for all out-of-pocket expenses (including the fees and disbursements of counsel) incurred by them. Notwithstanding any termination of this Agreement, the Company shall be liable for all expenses which it has agreed to pay pursuant to Section 5(k) hereof. Except as otherwise provided, this Agreement has been and is made solely for the benefit of and shall be binding upon the Company, the Underwriters, the Underwriters' directors and officers, any controlling persons referred to herein, the Company's directors and the Company's officers who sign the Registration Statement and their respective successors and assigns, all as and to the extent provided in this Agreement, and no other person shall acquire or have any right under or by virtue of this Agreement. The term "successors and assigns" shall not include a purchaser of any of the Notes from any of the several Underwriters merely because of such purchase. This Agreement shall be governed and construed in accordance with the laws of the State of New York without regard to the conflict of laws provisions thereof. -17- This Agreement may be signed in various counterparts which together shall constitute one and the same instrument. -18- Please confirm that the foregoing correctly sets forth the agreement between the Company and the Underwriters.
