The foregoing indemnity agreement is in addition to any liability that the Selling Shareholder may otherwise have to the Company, the Underwriter or any affiliate, director, officer, employee or controlling person of the Underwriter.

(c) The Underwriter shall indemnify and hold harmless the Company, the Selling Shareholder, their respective directors, officers and employees, and each person, if any, who controls the Company or the Selling Shareholder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company, the Selling Shareholder or any such director, officer, employee or controlling person of the Company or the Selling Shareholder may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto, any material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning the Underwriter furnished to the Company by the Underwriter specifically for inclusion therein, which information is limited to the information set forth in Section 10(f). The foregoing indemnity agreement is in addition to any liability that the Underwriter may otherwise have to the Company, the Selling Shareholder or any such director, officer, employee or controlling person of the Company or the Selling Shareholder.

(d) Promptly after receipt by an indemnified party under this Section 10 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 10, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 10 except to the extent it has been materially prejudiced (through the forfeiture of substantive rights and defenses) by such failure and, provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 10. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. 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 shall not be liable to the indemnified party under this Section 10 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 the indemnified party shall have the right to employ counsel to represent jointly the indemnified party and those other indemnified parties and their respective directors, officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought under this Section 10 if (i) the indemnified party and the indemnifying party shall have so mutually agreed; (ii) the indemnifying party has failed within a reasonable time after notice of the institution of such action to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party and its directors, officers, employees and controlling persons shall have reasonably concluded that there may be legal defenses available to them that are different from or in addition to those available to the indemnifying party and in the judgment of counsel to the indemnified party it is advisable to employ separate counsel or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnified parties or their respective directors, officers, employees or controlling persons, on the one hand, and the indemnifying party, on the other hand, and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the indemnifying party. It is understood that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate counsel (in addition to one local counsel) for all such indemnified parties except as provided in the preceding sentence. No indemnifying party shall (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld or delayed), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include any findings of fact or admissions of fault or culpability as to the indemnified party, or (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld or delayed), but if settled with the consent of the indemnifying party or if there be a final judgment for 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. 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 Section 10(a) or (b) hereof, 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 60 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 or disputed in good faith the indemnified party’s entitlement to such reimbursement prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 60 days prior notice of its intention to settle and the terms of such settlement.

(e) If the indemnification provided for in this Section 10 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 10(a), 10(b) or 10(c) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company, the Selling Shareholder and the Underwriter from the offering of the Shares 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, the Selling Shareholder and the Underwriter with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company, the Selling Shareholder and the Underwriter, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Shares purchased under this Agreement (before deducting expenses) received by the Selling Shareholder, as set forth in the table on the cover page of the Prospectus, on the one hand, and the total underwriting discounts and commissions received by the Underwriter with respect to the Shares purchased under this Agreement, as set forth in the table on the cover page of the Prospectus, on the other hand. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company, the Selling Shareholder or the Underwriter, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Selling Shareholder and the Underwriter agree that it would not be just and equitable if contributions pursuant to this Section 10(e) were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 10(e) shall be deemed to include, for purposes of this Section 10(e), 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 10(e), the Underwriter shall not be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by the Underwriter with respect to the offering of the Shares 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. Each party entitled to contribution agrees that upon the service of a summons or other initial legal process upon it in any action instituted against it in respect to which contribution may be sought, it will promptly give written notice of such service to the party or parties from whom contribution may be sought, but the omission so to notify such party or parties of any such service will not relieve the party from whom contribution may be sought for any obligation it may have hereunder or otherwise (except to the same extent as specifically provided in Section 10(d) above).

(f) The Underwriter confirms that the statements regarding delivery of Shares by the Underwriter set forth on the cover page of, and the concession and reallowance figures and the first two paragraphs under the caption “Underwriting—Stabilization, Short Positions and Penalty Bids,” in the most recent Preliminary Prospectus and the Prospectus are correct and the Underwriter, the Selling Shareholder and the Company acknowledge that such information constitute the only information concerning the Underwriter furnished in writing to the Company by the Underwriter specifically for inclusion in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto. The Selling Shareholder confirms that the statements set forth in the beneficial ownership table (including the footnotes thereto) in the most recent Preliminary Prospectus and the Prospectus under the caption “Selling Shareholder” are correct and the Selling Shareholder, the Company and the Underwriter acknowledge and agree that such information constitutes the only information concerning the Selling Shareholder furnished in writing to the Company specifically for inclusion in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto.

(g) The liability of the Selling Shareholder under this Section 10 shall not exceed the amount equal to the net proceeds (before deducting expenses) received by the Selling Shareholder from the sale of Shares by the Selling Shareholder pursuant to this Agreement.

11. [Reserved].

12. Termination. The obligations of the Underwriter hereunder may be terminated by the Underwriter by notice given to and received by the Company and the Selling Shareholder prior to delivery of and payment for the Shares if, prior to that time, any of the events described in Sections 9(m) and 9(n) shall have occurred or if the Underwriter shall decline to purchase the Shares for any reason permitted under this Agreement.

13. Reimbursement of Underwriter’s Expenses. If (a) the Selling Shareholder shall fail to tender the Shares for delivery to the Underwriter for any reason or (b) the Underwriter shall decline to purchase the Shares because any condition to the obligations of the Underwriter set forth in Section 9 hereof is not satisfied or because of any termination due to any of the events described in Sections 9(m) and 9(n) hereof, the Company will reimburse the Underwriter for all reasonable out-of-pocket expenses (including fees and disbursements of counsel for the Underwriter) incurred by the Underwriter in connection with this Agreement and the proposed purchase of the Shares, and upon demand and presentation of reasonable supporting documentation the Company shall pay the full amount thereof to the Underwriter.

14. Research Analyst Independence. The Company and the Selling Shareholder acknowledge that the Underwriter’s 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 the Underwriter’s research analysts may hold views 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 their respective investment banking divisions. The Company and the Selling Shareholder hereby waive and release, to the fullest extent permitted by law, any claims that the Company or the Selling Shareholder may have against the Underwriter with respect to any conflict of interest that may arise from the fact that the views expressed by its independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company or the Selling Shareholder by the Underwriter’s investment banking divisions. The Company and the Selling Shareholder acknowledge that the Underwriter 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 that may be the subject of the transactions contemplated by this Agreement.

15. No Fiduciary Duty. The Company and the Selling Shareholder acknowledge and agree that in connection with this offering, sale of the Shares or any other services the Underwriter may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriter: (i) no fiduciary or agency relationship between the Company, the Selling Shareholder and any other person, on the one hand, and the Underwriter, on the other, exists; (ii) the Underwriter is not acting as an advisor, expert or otherwise, to the Company or the Selling Shareholder, including, without limitation, with respect to the determination of the public offering price of the Shares, and such relationship between the Company and the Selling Shareholder, on the one hand, and the Underwriter, on the other, is entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Underwriter may have to the Company or the Selling Shareholder shall be limited to those duties and obligations specifically stated herein; and (iv) the Underwriter and its respective affiliates may have interests that differ from those of the Company and the Selling Shareholder. The Company and the Selling Shareholder hereby waive any claims that the Company or the Selling Shareholder may have against the Underwriter with respect to any breach of fiduciary duty in connection with this offering.

16. Notices, Etc. All statements, requests, notices and agreements hereunder shall be in writing, and:
