(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 paragraph (a) or (b) above, such person (the "indemnified party") shall promptly notify the person against whom such indemnity may be sought (the "indemnifying party") in writing 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. 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 -15- 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 Representative, in the case of parties indemnified pursuant to paragraph (a) above, and by the Company, in the case of parties indemnified pursuant to paragraph (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. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. 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 paragraph (a) or (b) of this Section 6 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 (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 (i) above but also the relative fault of the Company on the one hand and of the Underwriters 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 -16- (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 the Company on the one hand and of 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 by the Underwriters 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 6 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 6 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 paragraph (d) above. 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 6, 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 6 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. 7. TERMINATION. This Agreement shall be subject to termination, by notice given by the Representative to the Company, if (a) after the execution and delivery of the Underwriting Agreement and 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 National Association of Securities Dealers, Inc., the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or thee Chicago Board of Trade, (ii) trading of any securities of the Company shall have been suspended on any -17- 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 or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis that, in the judgment of the Representative, is material and adverse and (b) in the case of any of the events specified in clauses (a)(i) through (iv), such event, singly or together with any other such event, makes it, in the judgment of the Representative, impracticable to market the Bonds on the terms and in the manner contemplated in the Prospectus. This Agreement may also be terminated at any time prior to the Closing Date if in the judgment of the Representative the subject matter of any amendment or supplement to the Registration Statement or Prospectus prepared and furnished by the Company reflects a material adverse change in the business, properties or financial condition of the Company which renders it either inadvisable to proceed with such offering, if any, or inadvisable to proceed with the delivery of the Bonds to be purchased hereunder. 8. DEFAULTING UNDERWRITERS. If, on the Closing Date, any one or more of the Underwriters shall fail or refuse to purchase the Bonds that it has or they have agreed to purchase hereunder on such date, and the aggregate amount of 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 to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the amount of Bonds set forth opposite their respective names in the Underwriting Agreement bears to the aggregate amount of Bonds set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Representative 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 Bonds that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 8 by an amount in excess of one-ninth of such amount of Bonds without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Bonds that it has or they have agreed to purchase and the aggregate amount of Bonds with respect to which such default occurs is more than one-tenth of the aggregate amount of Bonds to be purchased on such date, and arrangements satisfactory to the Representative and the Company for the purchase of such Bonds are not made within 36 hours after such default, the Underwriting Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company. In any such case either the Representative 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 -18- under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under the Underwriting Agreement. If the Underwriting Agreement shall be terminated by the Underwriters, or any of them, 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 the Underwriting Agreement, or if for any reason the Company shall be unable to perform its obligations under the Underwriting Agreement, the Company will reimburse the Underwriters or such Underwriters as have so terminated the Underwriting Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with the Underwriting Agreement or the offering of the Bonds. If the Underwriting Agreement shall be terminated by the Company because of any failure or refusal on the part of the Underwriters to comply with the terms or to fulfill any of the conditions of the Underwriting Agreement, or if for any reason the Underwriters shall be unable to perform their obligations under the Underwriting Agreement, the Underwriters will reimburse the Company for all out-of-pocket expenses (including the fees and disbursements of its counsel) reasonably incurred by the Company in connection with the Underwriting Agreement or the offering of the Bonds. 9. REPRESENTATIONS AND INDEMNITIES TO SURVIVE. The respective indemnity and contribution agreements and the representations, warranties and other statements of the Company, its officers and the Underwriters set forth in the Underwriting Agreement will remain in full force and effect, regardless of any termination of the Underwriting Agreement, any investigation made by or on behalf of any Underwriter or the Company or any of the officers, directors or controlling persons referred to in Section 6 and delivery of and payment for the Bonds. 10. SUCCESSORS. This Agreement will enure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors and controlling persons referred to in Section 6, and no other person will have any right or obligation hereunder. 11. COUNTERPARTS. The Underwriting Agreement may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. 12. APPLICABLE LAW. The Underwriting Agreement shall be governed by and construed in accordance with the internal laws of the State of New York. -19- 13. HEADINGS. The headings of the sections of the Underwriting Agreement have been inserted for convenience of reference only and shall not be deemed a part of the Underwriting Agreement. 14. NOTICES.
