The obligations of the Underwriters to purchase the Offered Securities will be several and not joint. It is understood that the Underwriters propose to offer the Offered Securities for sale as set forth in the Prospectus. The Company and the Trust may specify in the Terms Agreement that the Company and the Trust thereby grant to the Underwriters the right (an "OVERALLOTMENT OPTION") to purchase at their election up to the number of Optional Securities set forth in such Terms Agreement, on the terms set forth in this section, for the sole purpose of covering over-allotments in the sale of the Firm Securities. Any such election to purchase Optional Securities may be exercised by written notice from the Representatives to the Company and the Trust, given within the period specified in the Terms Agreement, setting forth the aggregate number of Optional Securities to be purchased and the date on which such Optional Securities are to be delivered, as determined by the Representatives but in no event earlier than the Closing Date or, unless the Representatives, the Company and the Trust otherwise agree in writing, earlier than or later than the number of business days after the date of such notice set forth in such Terms Agreement.

Indemnification and Contribution. (a) The Company and the Trust, jointly and severally, will indemnify and hold harmless each Underwriter, its partners, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Act, against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Act 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 any material fact contained in the Registration Statement, the Prospectus, or any amendment or supplement thereto, or any related preliminary prospectus or preliminary prospectus supplement, 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 not misleading, and will reimburse each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred; 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 an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representatives, if any, specifically for use therein, it being understood and agreed that the only 16 17 such information furnished by any Underwriter consists of the information described as such in the Terms Agreement; and provided, further, that with respect to any untrue statement or alleged untrue statement in or omission or alleged omission from any preliminary prospectus the indemnity agreement contained in this subsection (a) shall not inure to the benefit of any Underwriter from whom the person asserting any such losses, claims, damages or liabilities purchased the Preferred Securities concerned, to the extent that a prospectus relating to such Preferred Securities was required to be delivered by such Underwriter under the Act in connection with such purchase and was not and if the Prospectus (as amended or supplemented) would have cured the defect giving rise to such loss, claim, damage or liability of such Underwriter unless such failure to deliver the Prospectus was the result of non-compliance by the Company with Section 4(e) hereof. (a) Each Underwriter will severally and not jointly indemnify and hold harmless the Company and the Trust, their directors and officers and each person, if any, who controls the Company or the Trust within the meaning of Section 15 of the Act, against any losses, claims, damages or liabilities to which the Company or the Trust may become subject, under the Act 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 any material fact contained in the Registration Statement, the Prospectus, or any amendment or supplement thereto, or any related preliminary prospectus or preliminary prospectus supplement, or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Company or the Trust by such Underwriter through the Representatives, if any, specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by the Company or the Trust in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses are incurred, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in the Terms Agreement. (b) Promptly after receipt by an indemnified party under this Section 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 subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action 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 (i) includes an unconditional release of such indemnified party from all liability on any claims that are 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 behalf of an indemnified party. (c) If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Trust on the one hand 17 18 and the Underwriters on the other from the offering of the Offered Securities 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 and the Trust on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company and the Trust on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault 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 Trust or the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Offered Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations in this subsection (d) to contribute are several in proportion to their respective underwriting obligations and not joint. (e) The obligations of the Company and the Trust under this Section shall be in addition to any liability which the Company or the Trust may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Act; and the obligations of the Underwriters under this Section shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each director of the Company and the Trust, to each officer of the Company and the Trust who has signed the Registration Statement and to each person, if any, who controls the Company or the Trust within the meaning of the Act. 8. Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Offered Securities under the Terms Agreement and the aggregate number of shares of Preferred Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total number of shares of Preferred Securities, the Lead Underwriter may make arrangements satisfactory to the Company and the Trust for the purchase of such Preferred Securities by other persons, including any of the Underwriters, but if no such arrangements are made by the Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments under the Terms Agreement (including the provisions of this Agreement), to purchase the Preferred Securities that such defaulting Underwriters agreed but failed to purchase. If any Underwriter or Underwriters so default and the aggregate number of shares of Preferred Securities with respect to which such default or defaults occur exceeds 10% of the total number of shares of Preferred Securities and arrangements satisfactory to the Lead Underwriter, the Company and the Trust for the purchase of such Preferred Securities by other persons are not made within 36 hours after such default, the Terms Agreement will terminate without liability on the part of any non-defaulting Underwriter, the Company or the Trust, except as provided in Section 8. As used in this Agreement, the term "Underwriter" includes any person substituted for an Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default. 18 19 9. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company, the Trust or their respective officers and of the several Underwriters set forth in or made pursuant to the Terms Agreement (including the provisions of this Agreement) will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the Company, the Trust or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If the Terms Agreement is terminated pursuant to Section 7 or if for any reason the purchase of the Offered Securities by the Underwriters is not consummated, the Company and the Trust shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 4 and the respective obligations of the Company, the Trust and the Underwriters pursuant to Section 6 shall remain in effect. If the purchase of the Preferred Securities by the Underwriters is not consummated for any reason other than solely because of the termination of the Terms Agreement pursuant to Section 7 or the occurrence of any event specified in clause (iii), (iv) or (v) of Section 5(d), the Company and the Trust will reimburse the Underwriters for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities. 10.

Representation of Underwriters. Any Representatives will act for the several Underwriters in connection with the financing described in the Terms Agreement, and any action under such Terms Agreement (including the provisions of this Agreement) taken by the Representatives jointly or by the Lead Underwriter will be binding upon all the Underwriters. 13.

The Terms Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement. 1.
