          (b) To advise the Underwriter promptly and, if requested by the Underwriter, confirm such advice in writing, (i) of the issuance by any state securities commission of any stop order suspending the qualification or exemption from qualification of the Shares for offering or sale in any jurisdiction designated by the Underwriter pursuant to Section 3(h) hereof, or the initiation of any proceeding by any state securities commission or any other federal or state regulatory authority for such purpose, and (ii) of the happening of any event within the period during which a prospectus is required by the Act to be delivered (whether physically or through compliance with Rule 172 under the Act or any similar rule) in connection with any sale of Shares, which event makes any statement of a material fact made in the Registration Statement, the Basic Prospectus, the Prospectus or any Permitted Free Writing Prospectus untrue or that requires any additions to or changes in the Registration Statement, the Basic Prospectus, the Prospectus or any Permitted Free Writing Prospectus in order to make the statements therein not misleading. The Company shall use its best efforts to prevent the issuance of any stop order or order suspending the qualification or exemption of the Shares under any state securities or Blue Sky laws and, if at any time any state securities commission or other federal or state regulatory authority shall issue an order

suspending the qualification or exemption of the Shares under any state securities or Blue Sky laws, the Company shall use its best efforts to obtain the withdrawal or lifting of such order at the earliest possible time.

The Company consents to the use of the Prospectus, and any amendments and supplements thereto required pursuant hereto, by the Underwriter in connection with the offering and sale of the Shares.

          (d) If it is necessary for any post-effective amendment to the Registration Statement to be declared effective before the offering of the Shares may commence, the Company will endeavor to cause such post-effective amendment to be declared effective as soon as possible and the Company will advise you promptly and, if requested by you, will confirm such advice in writing, (i) when such post-effective amendment to the Registration Statement has become effective, and (ii) if Rule 430A under the Act is used, when the Prospectus is filed with the Commission pursuant to Rule 424(b) under the Act (which the Company agrees to file in a timely manner in accordance with such Rules).

          (e) To advise you promptly and, if requested by you, to confirm such advice in writing, of any request by the Commission for amendments or supplements to the Registration Statement, the Basic Prospectus, the Prospectus or any Permitted Free Writing Prospectus or for additional information with respect thereto, or of notice of institution of proceedings for, or the entry of a stop order, suspending the effectiveness of the Registration Statement and, if the Commission should enter a stop order suspending the effectiveness of the Registration Statement, to use its best efforts to obtain the lifting or removal of such order as soon as possible.

time prior to any proposed filing and to file no such amendment or supplement to which you shall reasonably object in writing and (ii) to prepare promptly upon your reasonable request any amendment or supplement to the Registration Statement, the Basic Prospectus, the Prospectus or any Permitted Free Writing Prospectus which in the reasonable opinion of the counsel for the Underwriter is believed to be necessary under the Act.

          (g) To advise you promptly, during the period referred to in Section 3(f) above, if any event shall occur or condition shall exist as a result of which, it becomes necessary to amend or supplement the Registration Statement, the Basic Prospectus, the Prospectus or any Permitted Free Writing Prospectus in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or, if it is necessary to amend or supplement the Registration Statement, the Basic Prospectus, the Prospectus or any Permitted Free Writing Prospectus to comply with the Act, and forthwith to prepare and file with the Commission an appropriate amendment or supplement to such Registration Statement, Basic Prospectus, Prospectus or Permitted Free Writing Prospectus so that the statements therein, as so amended or supplemented, will not, in the light of the circumstances when it is so delivered, be misleading, or so that such Registration Statement, Basic Prospectus or Prospectus will comply with applicable law, and to furnish to the Underwriter and such other persons as the Underwriter may designate such number of copies thereof as the Underwriter may reasonably request.

          (b) Each Selling Stockholder, severally and not jointly, agrees to indemnify and hold harmless the Underwriter, its directors, its officers, affiliates and each

person, if any, who controls the Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages, liabilities and judgments (including, without limitation, any reasonable legal or other expenses incurred in connection with investigating or defending any matter, including any action that could give rise to any such losses, claims, damages, liabilities or judgments) caused by (i) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning such Selling Stockholder furnished in writing by or on behalf of such Selling Stockholder to the Company expressly for use in, the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Company becoming effective after the date of this Agreement), as such Registration Statement relates to such Selling Stockholder, or arises out of or is based upon any omission or alleged omission to state a material fact in such Registration Statement in connection with such information, which material fact was not contained in such information and which material fact was required to be stated in such Registration Statement or was necessary to make the statements in such information not misleading or (ii) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning such Selling Stockholder furnished in writing by or on behalf of such Selling Stockholder to the Company expressly for use in, the Disclosure Package, any Prospectus, in any Permitted Free Writing Prospectus, in any “issuer information” (as defined in Rule 433 under the Act) of the Company or in any Prospectus together with any combination of one or more of the Permitted Free Writing Prospectuses, if any, in each case as such document relates to such Selling Stockholder, or arises out of or is based upon any omission or alleged omission to state a material fact in such document in connection with such information concerning such Selling Stockholder, which material fact was not contained in such information and which material fact was required to be stated in such document or was necessary to make the statements in such information, in the light of the circumstances under which they were made, not misleading. Notwithstanding anything herein to the contrary, in no event shall the liability of any Selling Stockholder to provide indemnity pursuant to this Section 8(b), or contribution pursuant to Section 8(e), exceed an amount equal to the net amount received by such Selling Stockholder (after deducting any underwriting discounts or commissions but before deducting any other fees or expenses) from the sale of Shares pursuant hereto.

          (c) The Underwriter agrees to indemnify and hold harmless the Company and its directors and officers who have signed the Registration Statement, each Selling Stockholder and each person, if any, who controls the company or such Selling Stockholder (within the meaning of Section 15 of the Act or Section 20 of the Exchange Act) from and against any and all losses, claims, damages, liabilities and judgments (including, without limitation, any reasonable legal or other expenses incurred in connection with investigating or defending any matter, including any action that could give rise to any such losses, claims, damages, liabilities or judgments) which, jointly or severally, the Company, such Selling Stockholder or any such person may incur under the Act, the Exchange Act, the common law or otherwise, insofar as such loss, claim, damage, liability or judgment arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with

information concerning the Underwriter furnished in writing by or on behalf of the Underwriter to the Company expressly for use in, the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Company), or arises out of or is based upon any omission or alleged omission to state a material fact in such Registration Statement in connection with such information, which material fact was not contained in such information and which material fact was required to be stated in such Registration Statement or was necessary to make such information not misleading or (ii) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning the Underwriter furnished in writing by or on behalf of the Underwriter to the Company expressly for use in, the Disclosure Package, any Prospectus or a Permitted Free Writing Prospectus, or arises out of or is based upon any omission or alleged omission to state a material fact in such Prospectus or Permitted Free Writing Prospectus in connection with such information, which material fact was not contained in such information and which material fact was necessary in order to make the statements in such information, in the light of the circumstances under which they were made, not misleading.

          (d) In case any action shall be commenced involving any person in respect of which indemnity may be sought pursuant to Section 8(a), 8(b) or 8(c) (the “indemnified party”), the indemnified party shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party shall assume the defense of such action, including the employment of counsel reasonably satisfactory to the indemnified party and the payment of all reasonable fees and expenses of such counsel, as incurred (except that in the case of any action in respect of which indemnity may be sought pursuant to both Section 8(c) and Section 8(a) and/or Section 8(b), the Underwriter shall not be required to assume the defense of such action pursuant to this Section 8(d), but may employ separate counsel and participate in the defense thereof, but the fees and expenses of such counsel, except as provided below, shall be at the expense of the Underwriter). Any indemnified party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the indemnified party unless (i) the employment of such counsel shall have been specifically authorized in writing by the indemnifying party, (ii) the indemnifying party shall have failed to assume the defense of such action or employ counsel reasonably satisfactory to the indemnified party or (iii) the named parties to any such action (including any impleaded parties) include both the indemnified party and the indemnifying party, and the 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 (in which case the indemnifying party shall not have the right to assume the defense of such action on behalf of the indemnified party). In any such case, the indemnifying party shall not, in connection with any one 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 fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for all indemnified parties and all such reasonable fees and expenses shall be reimbursed as they are incurred. Such firm for the Underwriter, its directors, its officers, affiliates and any control persons of the Underwriter shall be designated in writing by the Underwriter; such firm for the

Company, its directors and officers who have signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company; and such firm for the Selling Stockholders shall be designated in writing by the Selling Stockholders. The indemnifying party shall not be obligated to indemnify and hold harmless any indemnified party from and against any and all losses, claims, damages, liabilities and judgments by reason of any settlement of any action effected without the indemnifying party’s written consent. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement or compromise of, or consent to the entry of judgment with respect to, any pending or threatened action in respect of which the indemnified party is or could have been a party and indemnity or contribution may be or could have been sought hereunder by the indemnified party, unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability on claims that are or could have been 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 on behalf of the indemnified party.

          (e) To the extent the indemnification provided for in this Section 8 is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages, liabilities or judgments referred to therein, then each indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities and judgments (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholders, on the one hand, and the Underwriter on the other hand, from the offering of the Shares or (ii) if the allocation provided by clause 8(e)(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 8(e)(i) above but also the relative fault of the Company and the Selling Stockholders, on the one hand, and the Underwriter, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or judgments, 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 hand, shall be deemed to be in the same proportion as the total net proceeds from the offering of the Shares (after underwriting discounts and commissions, but before deducting expenses) received by the Company and the Selling Stockholders, and the total underwriting discounts and commissions received by the Underwriter bear to the aggregate public offering price of the Shares, in each case as set forth in this Agreement. The relative fault of the Company, the Selling Stockholders and the Underwriter 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, the Selling Stockholders or by the Underwriter and the parties’ relative intent, 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 contribution pursuant to this Section 8(e) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding

paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or judgments referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such indemnified party in connection with investigating or defending any matter, including any action, that could have given rise to such losses, claims, damages, liabilities or judgments. Notwithstanding the provisions of this Section 8, the Underwriter shall not be required to contribute any amount in excess of the amount by which the total discounts and commissions received by the Underwriter exceeds the amount of any damages which the 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.

          (f) The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

The Company and the Selling Stockholders each agree that a final judgment in any such action, proceeding or counterclaim brought in any such court shall be conclusive and binding upon the Company and each Selling Stockholder and may be enforced in any other courts to the jurisdiction of which the Company or any Selling Stockholder is or may be subject, by suit upon such judgment.

16.

The Underwriter hereby expressly disclaims any fiduciary or similar obligations to the Company or any Selling Stockholder, either in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions, and the Company and the Selling Stockholders each hereby confirm their understanding and agreement to that effect. The Company, the Selling Stockholders and the Underwriter agree that they are each responsible for making their own independent judgments with respect to any such transactions and that any opinions or views expressed by the Underwriter to the Company or any Selling Stockholder regarding such transactions, including, but not limited to, any opinions or views with respect to the price or market for the Company’s securities, do not constitute advice or recommendations to the Company or any Selling Stockholder.
