Prospectus, the Registration Statement or the Prospectus (collectively, the “Offering Documents”), or any amendment or supplement thereto, or (B) in any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Shares (“Marketing Materials”), including any road show or investor presentations made to investors by the Company (whether in person or electronically), or (ii) the omission or alleged omission to state in the Offering Documents, or in any amendment or supplement thereto or in any Marketing Materials, a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Underwriter and each such director, officer, employee or controlling person for any legal or other expenses reasonably incurred by such Underwriter or any such director, officer, employee or controlling person in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Company shall 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 or omission or alleged omission made in the Offering Documents, or in any such amendment or supplement thereto, or in any Marketing Materials, in reliance upon and in conformity with written information furnished to the Company by any Underwriter through Xxxxxxx, Sachs & Co. and Xxxxxx Brothers Inc. expressly for use therein, which information consists solely of the information contained in Section 8(e) hereof; provided, further, that, the Company will not be liable to any Underwriter under the indemnity agreement in this subsection (a) with respect to any Preliminary Prospectus to the extent any such loss, claim, damage or liability of such Underwriter results from the fact that such Underwriter sold Shares to a person as to whom it shall be established that there was not sent or given, at or prior to the written confirmation of such sale, a copy of the Prospectus in any case where such delivery is required by the Act, if the Company has previously furnished copies thereof in sufficient quantity to such Underwriter and the loss, claim, damage or liability of such Underwriter results from an untrue statement or omission of a material fact contained in a Preliminary Prospectus which was identified at such time to such Underwriter and corrected in the Prospectus and such correction would have cured the defect giving rise to such loss, claim damage or liability. The foregoing indemnity agreement is in addition to any liability which the Company may otherwise have to the Underwriters or to any director, officer, employee or controlling person of the Underwriters.

(b) Each Underwriter will indemnify and hold harmless the Company, its directors, officers and employees and each person, if any, who controls the Company within the meaning of the Act, from and against any losses, claims, damages or liabilities, joint or several, or any action respect thereof, to which the Company or any such director, officer, employee or controlling person 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 (i) an untrue statement or alleged untrue statement of a material fact contained (A) in any Offering Document or (B) in any Marketing Materials, or (ii) the omission or alleged omission to state in any Offering Document, or in any amendment or supplement thereto or in any Marketing Materials 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 any Offering Document or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company by such Underwriter through Xxxxxxx, Sachs & Co. and Xxxxxx Brothers Inc. expressly for use therein, which information consists solely of the information contained in Section 8(e) hereof; and will reimburse the Company and any such director, officer, employee or controlling person for any legal or other expenses reasonably incurred by the Company or any such director, officer, employee or controlling person in connection with investigating or defending any such action or claim as such expenses

are incurred. The foregoing indemnity agreement is in addition to any liability which the Underwriters may otherwise have to the Company or any such director, officer, employee or controlling person.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 8 except to the extent it has been materially prejudiced by such failure; provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party, and, after notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party will not be liable to the indemnified party under such subsection for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that any indemnified party shall have the right to employ separate counsel in any such action and to participate in the defense thereof but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the employment thereof has been specifically authorized by the indemnifying party in writing, (ii) such 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 and in the reasonable judgment of such counsel it is advisable for such indemnified party to employ separate counsel or (iii) the indemnifying party has failed to assume the defense of such action and employ counsel reasonably satisfactory to the indemnified party, in which case, if such indemnified party notifies the indemnifying party in writing that it elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party shall not have the right to assume the defense of such action on behalf of such indemnified party, it being understood, however, that the indemnifying party 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 at any time (in addition to any one local counsel) for all such indemnified parties, which firm shall be designated in writing by the Underwriters, if the indemnified parties under this Section 8 consist of the Underwriters or any of its controlling persons, or by the Company, if the indemnified parties under this Section 8 consist of the Company or any of its directors, employees, officers or controlling persons. Each indemnified party, as a condition of the indemnity agreements contained in Sections 8(a) and 8(b), shall use its commercially reasonable efforts to cooperate with the indemnifying party in the defense of any such action or claim. Notwithstanding anything contained herein to the contrary, if indemnity may be sought pursuant to Section 8(f) hereof in respect of a claim or action referred to in Section 8(f), then in addition to such separate firm for the indemnified parties, the indemnifying party shall be liable for the reasonable fees and expenses of not more than one separate firm (in addition to any one local counsel per jurisdiction) for the Xxxxxx Brothers Entities (as defined in Section 8(f)) for the defense of any loss, claim, damage, liability or action arising out of the Directed Share Program. No indemnifying party shall, (i) without the written consent of the indemnified party (which consent will not be unreasonably withheld), effect the settlement or compromise of, or

consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (a) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (b) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party or (ii) be liable for any settlement of any such action effected without its written consent (which consent will not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment of the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(d) If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) 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 from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company 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 (or actions in respect thereof), 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 shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses other than the underwriting discounts and commissions) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. 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 on the one hand or the Underwriters on the other 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 contributions pursuant to this subsection (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 above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in 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 such action or claim. 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 discounts and commissions received by it 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 Underwriters confirm and the Company acknowledges that the statements with respect to the offering of the Shares by the Underwriters set forth in the fourteenth and fifteenth paragraph in the section captioned “Underwriting” in the Prospectus constitute the only information concerning the Underwriters furnished in writing to the Company by or on behalf of the Underwriters specifically for inclusion in the Prospectus.

(f) The Company shall indemnify and hold harmless Xxxxxx Brothers Inc. (including its directors, officers and employees) and each person, if any, who controls Xxxxxx Brothers Inc. within the meaning of Section 15 of the Act (collectively, the “Xxxxxx Brothers Entities”), from and against any loss, claim, damage or liability or any action in respect thereof to which any of the Xxxxxx Brothers Entities may become subject, under the Act or otherwise, insofar as such loss, claim, damage, liability or action (i) arises out of, or is based upon, any untrue statement or alleged untrue statement of a material fact contained in any material prepared by or with the approval of the Company for distribution to Directed Share Participants in connection with the Directed Share Program or 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, (ii) arises out of, or is based upon, the failure of the Directed Share Participant to pay for and accept delivery of Directed Shares that the Directed Share Participant agreed to purchase or (iii) is otherwise related to the Directed Share Program; provided that, the Company shall not be liable under this clause (iii) for any loss, claim, damage, liability or action that (A) is determined in a final judgment by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the Xxxxxx Brothers Entities or (B) is the subject of Section 8(b). The Company shall reimburse the Xxxxxx Brothers Entities promptly upon demand for any legal or other expenses reasonably incurred by them in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred.

9. (a) If any Underwriter shall default in its obligation to purchase the Shares which it has agreed to purchase hereunder at a Time of Delivery, you may in your discretion arrange for you or another party or other parties to purchase such Shares on the terms contained herein. If within thirty-six hours after such default by any Underwriter you do not arrange for the purchase of such Shares, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties reasonably satisfactory to you to purchase such Shares on such terms. In the event that, within the respective prescribed periods, you notify the Company that you have so arranged for the purchase of such Shares, or the Company notifies you that it has so arranged for the purchase of such Shares, you or the Company shall have the right to postpone such Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments to the Registration Statement or the Prospectus which may thereby be required under the Act. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Shares.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you and the Company as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased does not exceed one-eleventh of the aggregate number of all the Shares to be purchased at such Time of Delivery, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Shares which such Underwriter agreed to purchase hereunder at such Time of Delivery and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Shares which such Underwriter agreed to purchase

hereunder) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by you and the Company as provided in subsection (a) above, the aggregate number of such Shares which remains unpurchased exceeds one-eleventh of the aggregate number of all the Shares to be purchased at such Time of Delivery, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement (or, with respect to the Second Time of Delivery, the obligations of the Underwriters to purchase and of the Company to sell the Optional Shares) shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 6 hereof and the indemnity and contribution agreements in Section 8 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

10. The respective indemnities, agreements, representations, warranties and other statements of the Company and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, or the Company, or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Shares.

11. If this Agreement shall be terminated pursuant to Section 9 hereof, the Company shall not then be under any liability to any Underwriter except as provided in Sections 6 and 8 hereof; but, if for any other reason, any Shares are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Underwriters through you for all out-of-pocket expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Shares not so delivered, but the Company shall then be under no further liability to any Underwriter except as provided in Sections 6 and 8 hereof.

12. The Company acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold and make statements or investment recommendations and/or publish research reports with respect to the Company and/or the offering that differ from the views of its investment bankers. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that the Company may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company by such Underwriters’ investment banking divisions. The Company acknowledges that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies which may be the subject of the transactions contemplated by this Agreement.

13. In all dealings hereunder, you shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by you jointly.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to (i) Xxxxxxx, Xxxxx & Co., 00 Xxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: Registration Department and (ii) Xxxxxx Brothers Inc., 000 Xxxxxxx Xxxxxx, 00^xx Xxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: Syndicate Department; and if to the Company shall be delivered or sent by mail to the address of the Company set forth in the Registration Statement, Attention: Secretary; provided, however, that any notice to an Underwriter pursuant to Section 8(c) hereof shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its Underwriters’ Questionnaire, or telex constituting such Questionnaire, which address will be supplied to the Company by you upon request; provided, however, that notices under subsection 5(e) shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to (i) Xxxxxxx, Xxxxx & Co., 00 Xxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: Control Room and (ii) Xxxxxx Brothers Inc., 000 Xxxxxxx Xxxxxx, 00^xx Xxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attention: Syndicate Department. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

14. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Company and, to the extent provided in Section 8 hereof, the officers and directors of the Company and each person who controls the Company or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Shares from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

15. Time shall be of the essence of this Agreement. As used herein, the term “business day” shall mean any day when the Commission’s office in Washington, D.C. is open for business.

16. This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

17. This Agreement may be executed by any one or more of the parties hereto 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 instrument.

If the foregoing is in accordance with your understanding, please sign and return to us one for the Company and each of the Representatives plus one for each counsel counterparts hereof, and upon the acceptance hereof by you, on behalf of each of the Underwriters, this letter and such acceptance hereof shall constitute a binding agreement among each of the Underwriters and the Company.
