(b) The Company agrees to indemnify and hold harmless each of the Underwriters and each person, if any, who controls any such Underwriter within the meaning of Section 15 of the Securities 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 Securities Act or otherwise, and to reimburse the Underwriters and such controlling person or persons, if any, for any legal or other expenses incurred by them in connection with defending any actions, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in a Preliminary Prospectus (if used prior to the effective date of the registration statement), or in the Registration Statement, or in the Prospectus, in the Prospectus as so amended or supplemented (provided that, if such Prospectus or such Prospectus as amended or supplemented is used after the expiration of the period of time specified in Section 6(f) hereof, it shall contain such amendments or supplements as the Company deems necessary to comply with Section 10(a)(3) of the Securities Act), or arise out of or are based upon 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 actions arise out of or are based upon any such untrue statement or omission or alleged untrue statement or omission which was made in such Registration Statement or Prospectus in reliance upon and in conformity with information furnished in writing to the Company by, or through you on behalf of, any Underwriter for use therein and except that this indemnity with respect to a Preliminary Prospectus, and with respect to the Prospectus if the Company shall have furnished any amendment or supplement thereto, shall not inure to the benefit of any Underwriter (or of any person controlling such Underwriter) on account of any losses, claims, damages, liabilities or actions arising from the sale of Senior Notes to any person if a copy of the Prospectus, as the same may then be amended or supplemented, shall not have been sent or given by or on behalf of such Underwriter to such person with or prior to the written confirmation of the sale involved. Each Underwriter agrees, within ten days after the receipt by it of notice of the commencement of any action in respect of 7 which indemnity may be sought by it, or by any person controlling it, from the Company on account of its agreement contained in this Section 7(b), to notify the Company in writing of the commencement thereof, but the omission of such Underwriter so to notify the Company of any such action shall not release the Company from any liability which it may have to such Underwriter or to such controlling person otherwise than on account of the indemnity agreement contained in this Section 7(b). In case any such action shall be brought against any Underwriter or any such person controlling such Underwriter and such Underwriter shall notify the Company of the commencement thereof, as above provided, the Company shall be entitled to participate in (and, to the extent that it shall wish, including the selection of counsel, to direct) the defense thereof at its own expense. In case the Company elects to direct such defense and select such counsel, any Underwriter or controlling person shall have the right to employ its own counsel, but, in any such case, the fees and expenses of such counsel shall be at the expense of such Underwriter or controlling person unless the employment of such counsel has been authorized in writing by the Company in connection with defending such action. The Company's indemnity agreement contained in this Section 7(b), and its covenants, warranties and representations contained in this agreement, shall remain in full force and effect regardless of any investigation made by or on behalf of any Underwriter or controlling person, and shall survive the delivery of and payment for the Senior Notes hereunder. 8. Warranties of and Indemnity by Underwriters: (a) Each Underwriter warrants and represents to the Company, its directors and such of its officers as shall have signed the Registration Statement, and to each other Underwriter that the information furnished in writing to the Company by, or through you on behalf of, such Underwriter for use in the Registration Statement, any Preliminary Prospectus or the Prospectus does not contain an untrue statement of a material fact and does not omit to state a material fact in connection with such information required to be stated therein or necessary to make such information not misleading. (b) Each Underwriter agrees to indemnify and hold harmless the Company, its directors and such of its officers as shall have signed the Registration Statement, and each other Underwriter and each person, if any, who controls the Company or any such other Underwriter within the meaning of Section 15 of the Securities Act, to the same extent and upon the same terms as the indemnity agreement of the Company set forth in Section 7(b) hereof, but only with respect to untrue statements or omissions or alleged untrue statements or omissions made in the Registration Statement, any Preliminary Prospectus or the Prospectus, or the Prospectus as amended or supplemented, in reliance upon and in conformity with information furnished in writing to the Company by, or through you on behalf of, such Underwriter for use therein. The indemnity agreement on the part of each Underwriter contained in this Section 8(b), and the warranties and representations of such Underwriter contained in this Agreement, shall 8 remain in full force and effect regardless of any investigation made by or on behalf of the Company or other Underwriter or controlling person, and shall survive the delivery of and payment for the Senior Notes hereunder. 9. Substitution of Underwriters: If any Underwriter under this Agreement shall fail or refuse (whether for some reason sufficient to justify, in accordance with the terms hereof, the termination of its obligations to purchase or otherwise) to purchase the principal amount of the Senior Notes which it has agreed to purchase, the Company shall immediately notify you and you may, within 24 hours of receipt of such notice, procure some other responsible party or parties satisfactory to the Company, who may include one or more of the remaining Underwriters, to purchase or agree to purchase such principal amount of the Senior Notes on the terms herein set forth; and, if you shall fail to procure a satisfactory party or parties to purchase or agree to purchase such principal amount of the Senior Notes on such terms within such period after the receipt of such notice, then the Company shall be entitled to an additional period of 24 hours within which to procure another party or parties to purchase or agree to purchase such principal amount of the Senior Notes on the terms herein set forth. In any such case, either you or the Company shall have the right to postpone the Closing Date for a period not to exceed five full business days from the date set forth in Section 4 hereof, in order that the necessary changes in the Registration Statement and Prospectus and any other documents and arrangements may be effected. If you shall fail to procure a satisfactory party or parties to purchase or agree to purchase such principal amount of the Senior Notes, and if the Company also does not procure another party or parties to purchase or agree to purchase such principal amount of the Senior Notes, as above provided, then this agreement shall terminate. In the event of any such termination, the Company shall not be under any liability to any Underwriter (except to the extent, if any, provided in Section 6(j) hereof), nor shall any Underwriter (other than a Underwriter who shall have failed or refused to purchase Senior Notes without some reason sufficient to justify, in accordance with the terms hereof, its termination of its obligations hereunder) be under any liability to the Company. 10. Termination of Agreement: This Agreement may be terminated at any time prior to the time of purchase by you with the consent of Underwriters who have agreed to purchase in the aggregate 50% or more of the aggregate principal amount of the Senior Notes, if, after this agreement becomes effective and prior to the time of purchase, (i) trading in securities on the New York Stock Exchange shall have been generally suspended, (ii) minimum or maximum ranges for prices shall have been generally established on the New York Stock Exchange by the Commission or by the New York Stock Exchange, (iii) a general banking moratorium shall have been declared by federal or New York State authorities or (iv) there shall have occurred any outbreak or escalation of major hostilities in which the United States is involved, any declaration of war by the United States Congress or any other substantial national or international calamity or emergency affecting the United States, in any such case provided for in clauses (i) through (iv) with the result that, in your reasonable judgment, the marketability of the Senior Notes shall have been materially impaired. If you elect to terminate this Agreement, as provided in this Section 10, the Company and 9 each other Underwriter shall be notified promptly by you by telephone, confirmed in writing. If this agreement shall not be carried out by any Underwriter for any reason permitted hereunder, or if the sale of the Senior Notes to the Underwriters as herein contemplated shall not be carried out because the Company is not able to comply with the terms hereof, the Company shall not be under any obligation under this agreement and shall not be liable to any Underwriter or to any member of any selling group for the loss of anticipated profits from the transactions contemplated by this agreement (except that the Company shall remain liable to the extent provided in Section 6(j) hereof) and the Underwriters (other than a defaulting Underwriter) shall be under no liability to the Company nor be under any liability under this agreement to one another. 11.
