(j) Neither the Company nor any of the Subsidiaries shall have sustained since the date of the latest audited financial statements included in the Prospectus (A) any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth or contemplated in the Prospectus or (B) since such date, there shall not have been any material change in the capital stock, except as described in the Registration Statement, or long-term debt of the Company or any of the Subsidiaries or any change, or any development involving a prospective change, in or affecting the general affairs, management, financial position,

stockholders' equity or results of operations of the Company and the Subsidiaries, otherwise than as set forth or contemplated in the Prospectus, the effect of which, in any such case described in clause (A) or (B), is, in the judgment of the Representatives, so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Stock being delivered on such Delivery Date on the terms and in the manner contemplated in the Prospectus.

(k) Each Selling Stockholder (or the Custodian or one or more attorneys-in-fact on behalf of the Selling Stockholders) shall have furnished to the Representatives on the First Delivery Date a certificate, dated the First Delivery Date, signed by, or on behalf of, the Selling Stockholder (or the Custodian or one or more attorneys-in-fact) stating that the representations and warranties of the Selling Stockholder contained herein are true and correct as of the First Delivery Date and that the Selling Stockholder has complied with all agreements contained herein to be performed by the Selling Stockholder at or prior to the First Delivery Date.

(m) The Company shall have submitted a notification form for the listing of the Stock to the Nasdaq National Market System and shall have provided all additional materials and information, if any, requested by the Nasdaq National Market System in connection with such notification form.

(n) No Underwriter shall have discovered and disclosed to the Company on or prior to such Delivery Date that the Registration Statement or the Prospectus or any amendment or supplement thereto contains an untrue statement of a fact which, in the reasonable opinion of ▇▇▇▇▇▇, ▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP, counsel for the Underwriters, is material or omits to state a fact which, in the reasonable opinion of such counsel, is material and is required to be stated therein or is necessary to make the statements therein not misleading.

All opinions, letters, evidence and certificates mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in form and substance reasonably satisfactory to counsel for the Underwriters.

SECTION 11. Indemnification and Contribution.

(a) The Company shall indemnify and hold harmless each Underwriter, its directors, officers and employees and each person, if any, who controls any Underwriter within the meaning of the Securities Act, 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 that Underwriter, director, officer, employee or controlling person 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 any Preliminary Prospectus, the Registration Statement or the Prospectus or in 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 Stock, including any roadshow or investor presentations made to investors by the Company (whether in person or electronically) (the "Marketing Materials"), (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement or the Prospectus, or in any amendment or supplement thereto, or in any Marketing Materials, 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 any 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 such Underwriter through its gross negligence or willful misconduct), and shall reimburse each Underwriter and each such director, officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Underwriter, director, officer, employee or controlling person 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 any Preliminary Prospectus, the Registration Statement or the Prospectus, or in any such amendment or supplement, in reliance upon and in conformity with written information concerning such Underwriter furnished to the Company through the Representatives by or on behalf of any Underwriter specifically for inclusion therein which information consists solely of the information specified in Section 11(f); provided, however, that the Company shall not be liable to any Underwriter or person controlling such Underwriter under the indemnity agreement in this Section 11(a) to the extent, but only to the extent, that such loss, claim, damage, or liability of such Underwriter or person controlling such Underwriter results from the fact such Underwriter sold Stock to a person and there was not sent or given to such person, at or prior to the written confirmation of such sale to such person, to the extent required by law, a copy of the Prospectus dated the Effective Date (the "Final Prospectus") and the loss, claim, damage or liability of such Underwriter or person controlling such Underwriter results from an untrue statement or omission of a material fact contained in the Preliminary Prospectus previously delivered to such person which was corrected in the Final Prospectus, unless the Company had not previously furnished copies of the Final Prospectus in sufficient quantities to such Underwriter to permit delivery on a timely basis.

(b) The Selling Stockholders, severally in proportion to the number of shares of Stock to be sold by each of them hereunder and not jointly, shall indemnify and hold harmless each Underwriter, its officers and employees, and each person, if any, who controls any Underwriter within the meaning of the Securities Act, 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 that Underwriter, officer, employee or controlling person 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, alleged untrue statement, alledged omission of a material fact contained in any Preliminary Prospectus, the Registration Statement or the Prospectus, or in any amendment or

supplement thereto, or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement or the 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, alleged untrue statement, alleged omission or omission was made in reliance upon and in conformity with written information concerning such Selling Stockholder furnished to the Company by or on behalf of that Selling Stockholder specifically for inclusion therein, and shall reimburse each Underwriter, its officers and employees and each such controlling person for any legal or other expenses reasonably incurred by that Underwriter, its officers and employees or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred. Notwithstanding the foregoing sentence, the aggregate liability of any Selling Stockholder pursuant to the provisions of this paragraph shall be limited to an amount equal to the aggregate purchase price, less underwriting discounts and commissions, received by such Selling Stockholder from the sale of such Selling Stockholder's Stock hereunder. The foregoing indemnity agreement is in addition to any liability which the Selling Stockholders may otherwise have to any Underwriter or any officer, employee or controlling person of that Underwriter.

(c) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Company, its officers and employees, each of its directors (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the Company), each person, if any, who controls the Company within the meaning of the Securities Act and each Selling Stockholder from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company or any such director, officer, controlling person or Selling Stockholder 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, alleged untrue statement, alleged omission of a material fact contained in any Preliminary Prospectus, the Registration Statement or the Prospectus or in any amendment or supplement thereto, or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement or the 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, alleged untrue statement, alleged omission or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Underwriter furnished to the Company through the Representatives by or on behalf of that Underwriter specifically for inclusion therein, which information is limited to the information set forth in Section 11(f), and shall reimburse the Company and any such director (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the Company), officer, controlling person or Selling Stockholder for any legal or other expenses reasonably incurred by the Company or any such director, officer, controlling person or Selling Stockholder 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 foregoing indemnity agreement is in addition to any liability which any Underwriter may otherwise have to the Company or any such director, officer, employee, controlling person or Selling Stockholder.

(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; 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 Representatives shall have the right to employ counsel to represent jointly the Representatives and those other Underwriters and their respective 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 Underwriters against the Company under this Section 11 if, in the reasonable judgment of the Representatives, either (i) there is an actual or potential conflict between the position of the Company and the Underwriters, (ii) there may be defenses available to it or them that are different from or additional to those available to the Company (in any of which events the Company shall not have the right to direct the defense of such action on behalf of the Representative or Representatives with respect to such different defenses), or (iii) the Company has failed to assume to defense of such action and employ counsel reasonably satisfactory to the Representatives, in any of which events such fees and expenses shall be borne by the Company. 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, 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 Stockholders on the one hand and the Underwriters 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 Underwriters 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 Underwriters 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, on the one hand, and the total underwriting discounts and commissions received by the Underwriters with respect to the shares of the Stock purchased under this Agreement, on the other hand, bear

to the total gross proceeds from the offering of the shares of the Stock under this Agreement, 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 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 Underwriters, 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 Underwriters agree that it would not be just and equitable if contributions pursuant to this Section were to be 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 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 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), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the shares of Stock underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter 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. The Underwriters' obligations to contribute as provided in this Section 11(e) are several in proportion to their respective underwriting obligations and not joint.

(f) The Underwriters severally confirm and the Company and the Selling Stockholders acknowledge that the statements with respect to the public offering of the Stock by the Underwriters, the list of underwriters set forth on the cover page of the Prospectus and the concession and reallowance figures and the discussion concerning over allotments, stabilization, offering price determination, sales and purchases by the underwriters in the open market, underwriters penalty bids and short positions appearing under the caption "Underwriting" in the Prospectus are correct and constitute the only information concerning such Underwriters furnished in writing to the Company by or on behalf of the Underwriters specifically for inclusion in the Registration Statement and the Prospectus.

SECTION 12. Defaulting Underwriters.

If, on either Delivery Date, any Underwriter defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Underwriters shall be obligated to purchase the Stock which the defaulting Underwriter agreed but failed to purchase on such Delivery Date in the respective proportions which the number of shares of the Firm Stock set opposite the name of each remaining non-defaulting Underwriter in Schedule 1 hereto bears to the total number of shares of the Firm Stock set opposite the names of all the remaining non-defaulting Underwriters in Schedule 1 hereto; provided, however, that the remaining non-defaulting Underwriters shall not be obligated to purchase any of the Stock on such Delivery Date if the total number of shares of the Stock which the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 9.09% of the total number of shares of the Stock to be purchased on such Delivery Date, and any remaining non-defaulting Underwriter shall not be obligated to purchase more than 110% of the number of shares of the Stock which it agreed to purchase on such Delivery Date pursuant to the terms of Section 3. If the foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to the Representatives who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, all the Stock to be purchased on such Delivery Date. If the remaining Underwriters or other underwriters satisfactory

to the Representatives do not elect to purchase the shares which the defaulting Underwriter or Underwriters agreed but failed to purchase on such Delivery Date, this Agreement (or, with respect to the Second Delivery Date, the obligation of the Underwriters to purchase, and of the Company to sell, the Option Stock) shall terminate without liability on the part of any non-defaulting Underwriter or the Company, except that the Company will continue to be liable for the payment of expenses to the extent set forth in Sections 9 and 14. As used in this Agreement, the term "Underwriter" includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule 1 hereto who, pursuant to this Section 12, purchases Firm Stock which a defaulting Underwriter agreed but failed to purchase.

Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company for damages caused by its default. If other Underwriters are obligated or agree to purchase the Stock of a defaulting or withdrawing Underwriter, either the Representatives or the Company may postpone the Delivery Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement.

SECTION 13. Termination. The obligations of the Underwriters hereunder may be terminated by the Representatives by notice given to and received by the Company and the Selling Stockholders prior to delivery of and payment for the Firm Stock if, prior to that time, any of the events described in Sections 10(j) or 10(l), shall have occurred or if the Underwriters shall decline to purchase the Stock for any reason permitted under this Agreement.

SECTION 14. Reimbursement of Underwriters' Expenses. If the Company or any Selling Stockholder shall fail to tender the Stock for delivery to the Underwriters by reason of any failure, refusal or inability on the part of the Company or any Selling Stockholder to perform any agreement on its part to be performed, or because any other condition of the Underwriters' obligations hereunder required to be fulfilled by the Company or any Selling Stockholder is not fulfilled (unless such non-fulfillment is due to any action or inaction by an Underwriter including without limitation pursuant to Section 10(l)(iv) above), the Company will reimburse the Underwriters for all reasonable out-of-pocket expenses (including reasonable fees and disbursements of counsel) incurred by the Underwriters 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 Representatives. If this Agreement is terminated pursuant to Section 12 by reason of the default of one or more Underwriters, neither the Company nor any Selling Stockholder shall be obligated to reimburse any defaulting Underwriter for such out-of-pocket expenses.

SECTION 15. Notices, Etc. All statements, requests, notices and agreements hereunder shall be in writing, and:
