11. Indemnification and Contribution.

(a) The Company shall indemnify and hold harmless the Underwriter, its directors, officers, employees and agents and each person, if any, who controls the Underwriter within the meaning of Section 15 of the Securities Act, and any affiliate that has, or is alleged to have had, participated in the distribution contemplated hereby on behalf of the Underwriter, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Stock), to which the Underwriter, director, officer, employee, agent, controlling person or affiliate 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 (A) in the Registration Statement, any Preliminary Prospectus, the Pricing Disclosure Package or the Prospectus or in any amendment or supplement thereto, (B) any Issuer Free Writing Prospectus or in any amendment or supplement thereto, (C) any Permitted Issuer Information used or referred to in any “free writing prospectus” (as defined in Rule 405 under the Securities Act) used or referred to by the Underwriter or (D) any blue sky application or other document prepared or executed by the Company (or based upon any written information furnished by the Company for use therein) specifically for the purpose of qualifying any or all of the Stock under the securities laws of any state or other jurisdiction (any such application, document or information being hereinafter called a “Blue Sky Application”), (ii) the omission or alleged omission to state in the Registration Statement, any Preliminary Prospectus, the Pricing Disclosure Package, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Permitted Issuer Information or any Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) any act or failure to act or any alleged act or failure to act by the Underwriter in connection with, or relating in any manner to, the Stock or the offering contemplated hereby, and which is included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon matters covered by clause (i) or (ii) above (provided that the Company shall not be liable under this clause (iii) to the extent that it is determined in a final judgment by a court of competent jurisdiction that such loss, claim, damage, liability or action resulted directly from any such acts or failures to act undertaken or omitted to be taken by the Underwriter through its gross negligence or willful misconduct), and shall reimburse the Underwriter and each such director, officer, employee, agent, controlling person or affiliate promptly upon demand for any legal or other expenses reasonably incurred by the Underwriter, director, officer, employee, agent, controlling person or affiliate in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action 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, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, the Pricing Disclosure Package, the Prospectus, any Issuer Free Writing Prospectus or in any such amendment or supplement thereto or in any Permitted Issuer Information or any Blue Sky Application, in reliance upon and in conformity with written information concerning the Underwriter furnished to the Company by or on behalf of the Underwriter specifically for inclusion therein, which information consists solely of the information specified in Section 11(f). The foregoing indemnity agreement is in addition to any liability that the Company may otherwise have to the Underwriter or to any director, officer, employee, agent, controlling person or affiliate of the Underwriter.

(b) Each Selling Shareholder, severally and not jointly, shall indemnify and hold harmless the Underwriter, its directors, officers, employees and agents, and each person, if any, who controls the Underwriter within the meaning of Section 15 of the Securities Act, and any affiliate that has, or is alleged to have had, participated in the distribution contemplated hereby on behalf of the Underwriter, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Stock), to which the Underwriter, director, officer, employee, agent, controlling person or affiliate 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 the Registration Statement, any Preliminary Prospectus, the Pricing Disclosure Package, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Permitted Issuer Information, but only with respect to such statements made in reliance upon and in conformity with the Selling Shareholders Information provided by such Selling Shareholder, or any “free writing prospectus” (as defined in Rule 405 under the Securities Act), prepared by or on behalf of such Selling Shareholder or used or referred to by such Selling Shareholder in connection with the offering of the Stock in violation of Section 2(l) (a “Selling Shareholder Free Writing Prospectus”) or (ii) the omission or alleged omission to state in the Registration Statement, any Preliminary Prospectus, the Pricing Disclosure Package, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Permitted Issuer Information, but only with respect to omissions or alleged omissions made in reliance upon and in conformity with the Selling Shareholders Information provided by such Selling Shareholder, or any Selling Shareholder Free Writing Prospectus, any material fact required to be stated therein or necessary to make the statements therein not misleading (in light of the circumstances under which they were made, in each case other than in the Registration Statement), and shall reimburse the Underwriter, and each such director, officer, employee, agent, controlling person or affiliate promptly upon demand for any legal or other expenses reasonably incurred by the Underwriter, director, officer, employee, agent, controlling person or affiliate in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred. The liability of such Selling Shareholder under the indemnity agreement contained in this paragraph shall be limited to an amount equal to the aggregate gross proceeds after expenses from the offering of the shares of Stock purchased under this Agreement received by such Selling Shareholder (the “Selling Shareholder Amount”). The foregoing indemnity agreement is in addition to any liability that such Selling Shareholder may otherwise have to the Underwriter or to any director, officer, employee, agent, controlling person or affiliate of the Underwriter.

(c) The Underwriter shall indemnify and hold harmless the Company, the Selling Shareholders, their respective directors, managers, officers and employees and each person, if any, who controls the Company or such Selling Shareholders within the meaning of Section 15 of the Securities Act, and, in the case of the Company, affiliates of the Company, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company, such Selling Shareholders or any such director, manager, officer, employee, controlling person or Company affiliate 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 the Registration Statement, any Preliminary Prospectus, the Pricing Disclosure Package, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Blue Sky Application, or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Pricing Disclosure Package, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Blue Sky Application, 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 or on behalf of the Underwriter specifically for inclusion therein, which information is limited to the information set forth in Section 11(f) hereof. The foregoing indemnity agreement is in addition to any liability that the Underwriter may otherwise have to the Company, the Selling Shareholders or any such director, manager, officer, employee, controlling person or Company affiliate.

(d) Promptly after receipt by an indemnified party under this Section 11 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 11, 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 11 except to the extent it has been materially prejudiced 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 11. 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 11 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 Underwriter shall have the right to employ counsel (in addition to local counsel, if necessary) to represent the Underwriter and its directors, officers, employees, agents, controlling persons or affiliates who may be subject to liability arising out of

any claim in respect of which indemnity may be sought by the Underwriter against the Company or the Selling Shareholders under this Section 11 if (i) the Company, the Selling Shareholders and the Underwriter shall have mutually so agreed; (ii) the Company and the Selling Shareholders have failed within a reasonable time to retain counsel reasonably satisfactory to the Underwriter; (iii) the Underwriter and its directors, officers, employees, agents, controlling persons or affiliates 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 Company and the Selling Shareholders; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Underwriter or its directors, officers, employees, agents, controlling persons or affiliates, on the one hand, and the Company or the Selling Shareholders, 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 Company or the Selling Shareholders. No indemnifying party shall (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), 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 (whether or not the indemnified parties are actual or potential parties to such claim or action) 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), 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.

(e) If the indemnification provided for in this Section 11 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 11(a), 11(b) or 11(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 and the Selling Shareholders on the one hand and the Underwriter, on the other, from the offering of the Stock 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 Selling Shareholders, on the one hand, and the Underwriter, on the other, with respect to the statements or omissions which 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 and the Selling Shareholders, on the one hand, and the Underwriter, on the other, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Stock purchased under this Agreement (before deducting expenses) received by the Selling Shareholders, as set forth 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

of Stock purchased under this Agreement, 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 Shareholders 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 Shareholders and the Underwriter agree that it would not be just and equitable if contributions pursuant to this Section 11(e) were to be determined by pro rata allocation or by any other method of allocation which 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 11(e) shall be deemed to include, for purposes of this Section 11(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 11(e), the Underwriter shall not be required to contribute any amount in excess of the underwriting commissions received by the Underwriter in connection with the Stock underwritten by it and distributed to the public, and no Selling Shareholder shall be required to contribute any amount in excess of the amount by which the Selling Shareholder Amount exceeds the amount of any damages that such Selling Shareholder has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. The Selling Shareholders’ obligations to contribute pursuant to this section are several in proportion to their respective Selling Shareholder Amounts and not joint, and shall be limited to an amount equal to the aggregate offering price of the shares of Stock less the expenses by the Selling Shareholders pursuant to this Agreement. 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.

(f) The Underwriter confirms and the Company and the Selling Shareholders acknowledge and agree that the statements set forth in the second sentence of the third paragraph on the cover page of, and with respect to the concession and reallowance figures and the paragraph relating to stabilization by the Underwriter appearing under the caption “Underwriting” in, the Prospectus are correct and constitute the only information concerning the Underwriter furnished in writing to the Company by or on behalf of the Underwriter specifically for inclusion in any Preliminary Prospectus, the Registration Statement, the Pricing Disclosure Package, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto.

12. Default by one or more of the Selling Shareholders. If a Selling Shareholder shall fail at the Delivery Date to sell and deliver the number of shares of Stock which such Selling Shareholder or Selling Shareholders are obligated to sell hereunder (the “Defaulting Selling Shareholder(s)”), the remaining Selling Shareholder(s) may take up and pay for, pro rata or otherwise, the number of shares of Stock to be sold by the Defaulting Selling Shareholder(s) hereunder to the total number to be sold by all Selling Shareholders as set forth in Schedule 1 hereto. If the non-defaulting Selling Shareholder(s) do not exercise such right to take up and pay for the shares of the Defaulting Selling Shareholder(s), as provided for in this Section 12, then (i) the Underwriter, the Company and the non-defaulting Selling Shareholder(s) shall have the right to postpone the Delivery Date, as the case may be, for a period not exceeding seven days in order

to effect any required change in the Registration Statement, the Preliminary Prospectus, the Pricing Disclosure Package, the Prospectus or in any other documents or arrangements or (ii) the Underwriter may, by notice to the Company and the non-defaulting Selling Shareholder(s), terminate this Agreement without any liability on the fault of any non-defaulting party except that the provisions of Sections 1, 2, 11, 14, 19 and 21 shall remain in full force and effect; provided that, the Underwriter may not terminate this Agreement pursuant to clause (ii) above unless the number of shares of Stock to be sold by the Defaulting Selling Shareholder(s) is 20% or more of the total number of shares of Stock to be sold by all Selling Shareholders as set forth in Schedule 1 hereto. No action taken pursuant to this Section 12 shall relieve any Selling Shareholder so defaulting from liability, if any, in respect of such default.

13. 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 Shareholders prior to delivery of and payment for the Stock if, prior to that time, any of the events described in Sections 10(n), 10(o), 10(p), 10(q) or 10(r) shall have occurred or if the Underwriter shall decline to purchase the Stock for any reason permitted under this Agreement.

14. Reimbursement of Underwriter’s Expenses. If (a) the Company or the Selling Shareholders shall fail to tender the Stock for delivery to the Underwriter by reason of any failure, refusal or inability on the part of the Company or the Selling Shareholders to perform any agreement on their part to be performed, or because any other condition to the Underwriter’s obligations hereunder required to be fulfilled by the Company or the Selling Shareholders is not fulfilled for any reason or (b) the Underwriter shall decline to purchase the Stock for any reason permitted under this Agreement, the Company will reimburse the Underwriter for all reasonable and documented out-of-pocket expenses (including the fees and disbursements of counsel) incurred by the Underwriter in connection with this Agreement and the proposed purchase of the Stock, and upon demand the Company shall pay the full amount thereof to the Underwriter; provided, that the Company shall be permitted to recover against any defaulting Selling Shareholder for its pro rata portion (based on the number of shares of Stock proposed to be sold pursuant to this Agreement) of such expenses.

15. Research Independence. The Company and each of the Selling Shareholders acknowledge and agree that the Underwriter’s research analysts and research departments are required to be independent from its investment banking division and are subject to certain regulations and internal policies, and that the Underwriter’s 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 banking division. The Company and each of the Selling Shareholders hereby waives and releases, to the fullest extent permitted by law, any claims that the Company or such 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 such Selling Shareholder by the Underwriter’s investment banking division.
