INDEMNIFICATION AND CONTRIBUTION: (a) To the extent permitted by law, the Offerors agree to indemnify and hold you harmless, your officers and directors and each person, if any, who controls you within the meaning of Section 15 of the Act, against any and all losses, claims, damages or liabilities, joint or several, to which you, they or any of you or them may become subject under the Act or otherwise, and to reimburse you and such controlling person or persons, if any, for any legal or other expenses incurred by you or them in connection with defending any action, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any alleged untrue statement or untrue statement of a material fact contained in the Registration Statement, in the Basic Prospectus (if used prior to the effective date of this Agreement), or in the Prospectus, or if the Offerors shall furnish or cause to be furnished to you any amendments or any supplements to 13 the Prospectus, in the Prospectus as so amended or supplemented except to the extent that such amendments or supplements relate solely to securities other than the Preferred Securities (provided that if such Prospectus or such Prospectus, as amended or supplemented, is used after the period of time referred to in Section 4(b) hereof, it shall contain such amendments or supplements as the Offerors deem necessary to comply with Section 10(a) of the Act), or arise out of or are based upon any alleged omission or 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 alleged untrue statement or omission, or untrue statement or omission which was made in the Registration Statement, in the Basic Prospectus or in the Prospectus, or in the Prospectus as so amended or supplemented, in reliance upon and in conformity with information furnished in writing to the Offerors by or through the Representative expressly for use therein or with any statements in or omissions from that part of the Registration Statement that shall constitute the Statement of Eligibility under the 1939 Act of any trustee under any indenture, trust or other agreement or obligation of the Trust or of the Company with respect to the transactions contemplated by this Agreement, and except that this indemnity shall not inure to your benefit (or of any person controlling you) on account of any losses, claims, damages, liabilities or actions arising from the sale of the Preferred Securities to any person if such loss arises from the fact that a copy of the Prospectus, as the same may then be supplemented or amended to the extent such Prospectus was provided to you by the Offerors (excluding, however, any document then incorporated or deemed incorporated therein by reference), was not sent or given by you to such person with or prior to the written confirmation of the sale involved and the alleged omission or alleged untrue statement or omission or untrue statement was corrected in the Prospectus as supplemented or amended at the time of such confirmation, and such Prospectus, as amended or supplemented, was timely delivered to you by the Offerors. You agree promptly after the receipt by you of written notice of the commencement of any action in respect to which indemnity from either Offeror on account of its agreement contained in this Section 7(a) may be sought by you, or by any person controlling you, to notify the Offerors in writing of the commencement thereof, but your omission so to notify the Offerors of any such action shall not release either Offeror from any liability which it may have to you or to such controlling person otherwise than on account of the indemnity agreement contained in this Section 7(a). In case any such action shall be brought against you or any such person controlling you and you shall notify the Offerors of the commencement thereof, as above provided, the 14 Offerors shall be entitled to participate in, and, to the extent that each shall wish, including the selection of counsel (such counsel to be reasonably acceptable to the indemnified party), to direct the defense thereof at the expense of the Offerors. In case the Offerors elect to direct such defense and select such counsel (hereinafter, Offerors' counsel), you or any controlling person shall have the right to employ your own counsel, but, in any such case, the fees and expenses of such counsel shall be at your expense unless (i) the Offerors have agreed in writing to pay such fees and expenses or (ii) the named parties to any such action (including any impleaded parties) include both you or any controlling person and the Offerors and you or any controlling person shall have been advised by your counsel that a conflict of interest between the Offerors and you or any controlling person may arise (and the Offerors' counsel shall have concurred in good faith with such advice) and for this reason it is not desirable for the Offerors' counsel to represent both the indemnifying party and the indemnified party (it being understood, however, that the Offerors shall not, in connection with any one such 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 reasonable fees and expenses of more than one separate firm of attorneys for you or any controlling person (plus any local counsel retained by you or any controlling person in their reasonable judgment), which firm (or firms) shall be designated in writing by you or any controlling person). (b) Each Underwriter agrees, to the extent permitted by law, severally and not jointly, to indemnify, hold harmless and reimburse the Company, its directors and such of its officers as shall have signed the Registration Statement, the Trust and each person, if any, who controls either Offeror within the meaning of Section 15 of the Act, to the same extent and upon the same terms as the indemnity agreement of the Offerors set forth in Section 7(a) hereof, but only with respect to untrue statements or alleged untrue statements or omissions or alleged omissions made in the Registration Statement, or in the Basic Prospectus, or in the Prospectus, or in the Prospectus as so amended or supplemented, in reliance upon and in conformity with information furnished in writing to the Offerors by the Representative on behalf of such Underwriter expressly for use therein. The Offerors agree promptly after the receipt by it of written notice of the commencement of any action in respect to which indemnity from you on account of your agreement contained in this Section 7(b) may be sought by the Offerors, or by any person controlling the Offerors, to notify you in writing of the commencement thereof, but the Offerors' omission so to notify you of any such action shall not release you from any liability which you 15 may have to the Offerors or to such controlling person otherwise than on account of the indemnity agreement contained in this Section 7(b). (c) If recovery is not available or insufficient under Section 7(a) or 7(b) hereof for any reason other than as specified therein, the indemnified party shall be entitled to contribution for any and all losses, claims, damages, liabilities and expenses for which such indemnification is so unavailable or insufficient under this Section 7(c). In determining the amount of contribution to which such indemnified party is entitled, there shall be considered the portion of the proceeds of the offering of the Preferred Securities realized, the relative knowledge and access to information concerning the matter with respect to which the claim was asserted, the opportunity to correct and prevent any statement or omission, and any equitable considerations appropriate under the circumstances. The Offerors and the Underwriters agree that it would not be equitable if the amount of such contribution were determined by pro rata or per capita allocation (even if the Underwriters were treated as one entity for such purpose) without reference to the considerations called for in the previous sentence. No Underwriter or any person controlling such Underwriter shall be obligated to contribute any amount or amounts hereunder which in the aggregate exceeds the total price of the Preferred Securities purchased by such Underwriter under this Agreement, less the aggregate amount of any damages which such Underwriter and its controlling persons have otherwise been required to pay in respect of the same claim or any substantially similar claim. 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. An Underwriter's obligation to contribute under this Section 7 is in proportion to its purchase obligation and not joint with any other Underwriter. (d) No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 7 (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or 16 an admission of fault, culpability or a failure to act by or on behalf of such indemnified party. (e) In no event shall any indemnifying party have any liability or responsibility in respect of the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim effected without its prior written consent. The agreements contained in this Section 7 hereof shall remain in full force and effect regardless of any investigation made by or on behalf of any person, and shall survive the delivery of and payment for the Preferred Securities hereunder. 8. DEFAULT OF UNDERWRITERS: If any Underwriter under this Agreement shall fail or refuse (otherwise than for some reason sufficient to justify, in accordance with the terms hereof, the cancellation or termination of its obligations hereunder) to purchase and pay for the aggregate number of Preferred Securities which it has agreed to purchase and pay for hereunder, and the aggregate number of Preferred Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Preferred Securities, the other Underwriters shall be obligated severally in the proportions which the aggregate number of Preferred Securities set forth opposite their names in Exhibit 1 hereto bear to the aggregate number of Preferred Securities set forth opposite the names of all such non-defaulting Underwriters, to purchase the Preferred Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on the terms set forth herein; provided that in no event shall the aggregate number of Preferred Securities which any Underwriter has agreed to purchase pursuant to Section 1 hereof be increased pursuant to this Section 8 by an amount in excess of one-ninth of such aggregate number of Preferred Securities without the written consent of such Underwriter. If any Underwriter or Underwriters shall fail or refuse to purchase Preferred Securities and the aggregate number of Preferred Securities with respect to which such default occurs is more than one-tenth of the aggregate number of the Preferred Securities then this Agreement shall terminate without liability on the part of any non-defaulting Underwriter; provided, however, that the non-defaulting Underwriters may agree, in their sole discretion, to purchase the Preferred Securities which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on the terms set forth herein. In the event of any such termination, the Offerors shall not be under any liability to any Underwriter (except to the extent, if any, provided in Section 4(h) hereof), nor shall any Underwriter (other than an Underwriter who shall have failed or refused to purchase the Preferred Securities without some reason sufficient to justify, in accordance with the terms hereof, its termination of its obligations hereunder) be under any liability to the Offerors or any other Underwriter. Nothing herein contained shall release any defaulting Underwriter from its liability to the Offeror or any non-defaulting Underwriter for damages occasioned by its default hereunder. 17 9. TERMINATION OF AGREEMENT BY THE UNDERWRITERS: This Agreement may be terminated at any time prior to the Time of Purchase by the Representative if, after the execution and delivery of this Agreement and prior to the Time of Purchase, in the Representative's reasonable judgment, the Underwriters' ability to market the Preferred Securities shall have been materially adversely affected because: (i) trading in securities on the New York Stock Exchange shall have been generally suspended by the Commission or by the New York Stock Exchange or trading in the securities of the Company shall have been suspended by the New York Stock Exchange, or (ii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war or other national or international calamity or crisis, or (iii) a general banking moratorium shall have been declared by Federal or New York State authorities, or (iv) there shall have been any decrease in the ratings of the Company's debt securities by Moody's Investors Services, Inc. (Moody's) or Standard & Poor's Ratings Services (S&P) or either Moody's or S&P shall publicly announce that it has such debt securities under consideration for possible further downgrade other than what has been announced. If the Representative elects to terminate this Agreement, as provided in this Section 9, the Representative will promptly notify the Offerors by telephone or by telex or facsimile transmission, 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 Preferred Securities to the Underwriters as herein contemplated shall not be carried out because the Offerors are not able to comply with the terms hereof, the Offerors 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 Offerors shall remain liable to the extent provided in Section 4(h) hereof) and the Underwriters shall be under no liability to the Offerors nor be under any liability under this Agreement to one another. 10.
