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 and controlling persons 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 Stockholders under this Section 11 if (i) the Company, the Selling Stockholders and the Underwriter shall have mutually so agreed; (ii) the Company and the Selling Stockholders have failed within a reasonable time to retain counsel reasonably satisfactory to the Underwriter; or (iii) the named parties in any such proceeding (including any impleaded parties) include both the Underwriter or its directors, officers, employees or controlling persons, on the one hand, and the Company and the Selling Stockholders, on the other hand, and representation of both sets of parties by the same counsel would, in the opinion of counsel to the Underwriter, present such counsel with a conflict of interest, and in any such event the fees and expenses of such separate counsel shall be paid by the Company or the Selling Stockholders. 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 or delayed), 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 Stockholders 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 Stockholders, 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 Stockholders, 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 Company and the Selling Stockholders, 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 of Stock 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 Stockholders 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 Stockholders 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 amount by which the net proceeds from the sale of the Stock underwritten by it exceeds the amount of any damages that the Underwriter has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission, and no Selling Stockholder shall be required to contribute any amount in excess of the amount by which the gross proceeds received by it from the sale of the Stock exceeds the amount of any damages that such Selling Stockholder has otherwise paid or become liable to pay by reason of any 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.

(f)The Underwriter confirms and the Company and the Selling Stockholders acknowledge and agree that the following information is correct and constitutes the only

information concerning the Underwriter furnished in writing to the Company by or on behalf of the Underwriter specifically for inclusion in the Pricing Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Non-Prospectus Road Show: (i) the statements regarding delivery of shares by the Underwriter set forth on the cover page of the Prospectus, (ii) the concession and reallowance figures in the Prospectus, (iii) the statements appearing in the first two paragraphs under the caption “Underwriting - Commissions and Expenses” in the Prospectus, (iv) the statements appearing in the second paragraph under the caption “Underwriting – Lock-Up Agreements” in the Prospectus, (v) the statements appearing under the caption “Underwriting – Stabilization and Short Positions” in the Prospectus, (vi) the statements appearing under the caption “Underwriting – Passive Market Making” in the Prospectus, (vii) the statements appearing under the caption “Underwriting – Electronic Distribution” in the Prospectus and (viii) the statements appearing under the caption “Underwriting – Selling Restrictions” in the Prospectus.

12.Termination. The obligations of the Underwriter hereunder may be terminated by notice given to and received by the Company and the Selling Stockholders prior to delivery of and payment for the Stock if, prior to that time, any of the events described in Sections 10(o), 10(p) or 10(q), shall have occurred or if the Underwriter shall decline to purchase the Stock for any reason permitted under this Agreement.

13.Reimbursement of Underwriter’s Expenses. If (a) the Selling Stockholders 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 Stockholders 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 Stockholders 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 and the Selling Stockholders will jointly and severally reimburse the Underwriter for all reasonable 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 and the Selling Stockholders shall pay the full amount thereof to the Underwriter but the Company and the Selling Stockholders shall have no further liability to the Underwriter in respect of the shares of Stock not delivered except as provided in Sections 9 and 11 hereof.

14.Research Independence. The Company and each of the Selling Stockholders acknowledge and agree that the Underwriter’s research analysts and research departments are required to be independent from its respective 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 Stockholders hereby waive and release, to the fullest extent permitted by law, any claims that the Company or such Selling Stockholder 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 Stockholder by the Underwriter’s investment banking division. The Company and each

of the Selling Stockholders 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 Company which may be the subject of the transactions contemplated by this Agreement.

15.No Fiduciary Duty. The Company and each of the Selling Stockholders acknowledge and agree that in connection with this offering, sale of the Stock 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 Stockholders and any other person, on the one hand, and the Underwriter, on the other, exists; (ii) the Underwriter is not acting as advisor, expert or otherwise, to either the Company or the Selling Stockholders, including, without limitation, with respect to the determination of the public offering price of the Stock, and such relationship between the Company and the Selling Stockholders, 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 Stockholders shall be limited to those duties and obligations specifically stated herein; and (iv) the Underwriter and its affiliates may have interests that differ from those of the Company and the Selling Stockholders. The Company and each of the Selling Stockholders hereby waive any claims that the Company or such Selling Stockholder may have against the Underwriter with respect to any breach of fiduciary duty in connection with this offering.
