The execution and delivery of this Agreement and the consummation by such Selling Stockholder of the transactions herein contemplated and the fulfillment by such Selling Stockholder of the terms hereof will not require such Selling Stockholder to obtain any consent, approval, authorization, or other order of any court, regulatory body, administrative agency or other governmental body (except as may be required under the Act, state securities laws or Blue Sky laws) and will not result in a breach of any of the terms and provisions of, or constitute a default under, organizational documents of such Selling Stockholder, if not an individual, or any indenture, mortgage, deed of trust or other agreement or instrument to which such Selling Stockholder is a party, or of any order, rule or regulation applicable to such Selling Stockholder of any court or of any regulatory body or administrative agency or other governmental body having jurisdiction, except for any such violation, conflict or breach that would not adversely affect the ability of such Selling Stockholder to perform its obligations under this Agreement, the Custodian Agreement and the Power of Attorney, as applicable, or to consummate the transactions contemplated hereby and thereby.

(iii) Such Selling Stockholder has not taken and will not take, directly or indirectly, any action designed to, or which has constituted, or which might reasonably be expected to cause or result in the stabilization or manipulation of the price of the Common Stock of the Company and, other than as permitted by the Act, the Selling Stockholder will not distribute any prospectus or other offering material in connection with the offering of the Shares.

(iv) As of its applicable effective date, as of the Applicable Time and as of the Closing Date, as the case may be, none of the Registration Statement, any Preliminary Prospectus, the General Disclosure Package, any Issuer Free Writing Prospectus, the Prospectus, any Testing-the-Waters Writing, or any amendment or supplement thereto, included or will include any untrue statement of a material fact or omitted or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that such Selling Stockholder’s representations under this Section 1(b)(iv) shall only apply to any untrue statement of a material fact or omission to state a material fact made in reliance upon and in conformity with information furnished by such Selling Stockholder to the Company by such Selling Stockholder expressly for use in the Registration Statement, any Preliminary Prospectus, the General Disclosure Package, any Issuer Free Writing Prospectus, the Prospectus, any Testing-the-Waters Writing, or any amendment or supplement thereto, it being understood and agreed that the only such information furnished by such Selling Stockholder consists of the name of such Selling Stockholder, the number of offered Shares and the address and other information with respect to such Selling Stockholder (excluding percentages) that appear in the table (and corresponding footnotes) under the caption “Principal and Selling Stockholders” (the “Selling Stockholder Information”).

(v) No consent, approval or waiver is required under any instrument or agreement to which such Selling Stockholder is a party or by which such Selling Stockholder is bound or under which he or it is entitled to any right or benefit, in connection with the offering, sale

or purchase by the Underwriters of any of the Shares which may be sold by such Selling Stockholder under this Agreement or the consummation by such Selling Stockholder of any of the other transactions contemplated hereby.

(vi) There are no affiliations or associations between any member of FINRA and such Selling Stockholder or any affiliate of such Selling Stockholder, except as set forth in the Registration Statement, General Disclosure Package and the Prospectus.

PURCHASE, SALE AND DELIVERY OF THE FIRM SHARES.

(a) On the basis of the representations, warranties and covenants herein contained, and subject to the conditions herein set forth, the Sellers agree to sell to the Underwriters and each Underwriter agrees, severally and not jointly, to purchase, at a price of $[—] per share, the number of Firm Shares set forth opposite the name of each Underwriter in Schedule I hereof, subject to adjustments in accordance with Section 9 hereof. The number of Firm Shares to be purchased by each Underwriter from each Seller shall be as nearly as practicable in the same proportion to the total number of Firm Shares being sold by each Seller as the number of Firm Shares being purchased by each Underwriter bears to the total number of Firm Shares to be sold hereunder. The obligations of the Company and of each of the Selling Stockholders shall be several and not joint.

(b) Certificates in negotiable form for the total number of the Firm Shares to be sold hereunder by the Selling Stockholders have been placed in custody with American Stock Transfer & Trust Company, LLC as custodian (the “Custodian”) pursuant to the Custodian Agreement executed by each Selling Stockholder for delivery of all Firm Shares to be sold hereunder by the Selling Stockholders. Each of the Selling Stockholders specifically agrees that the Firm Shares represented by the certificates or book-entry credits held in custody for the Selling Stockholders under the Custodian Agreement are subject to the interests of the Underwriters hereunder, that the arrangements made by the Selling Stockholders for such custody are to that extent irrevocable, and that the obligations of the Selling Stockholders hereunder shall not be terminable by any act or deed of the Selling Stockholders (or by any other person, firm or corporation including the Company, the Custodian or the Underwriters) or by operation of law (including the death of an individual Selling Stockholder or the dissolution of an entity that is a Selling Stockholder) or by the occurrence of any other event or events, except as set forth in the Custodian Agreement. If any such event should occur prior to the delivery to the Underwriters of the Firm Shares hereunder, certificates or book-entry credits for the Firm Shares shall be delivered by the Custodian in accordance with the terms and conditions of this Agreement as if such event has not occurred. The Custodian is authorized to receive and acknowledge receipt of the proceeds of sale of the Firm Shares held by it against delivery of such Firm Shares.

(c) Payment for the Firm Shares to be sold hereunder is to be made in Federal (same day) funds to an account designated by the Company for the shares to be sold by it and to an account designated by the Custodian for the shares to be sold by the Selling Stockholders, in each case, against delivery of certificates or book-entry credits therefor to the Representatives for the several accounts of the Underwriters. Such payment and delivery are to be made through the facilities of

The Depository Trust Company at 10:00 a.m., New York time, on the third business day after the date of this Agreement or at such other time and date not later than five business days thereafter as you and the Company shall agree upon, such time and date being herein referred to as the “Closing Date.” As used herein, “business day” means a day on which the Nasdaq Stock Market is open for trading and on which banks in New York are open for business and not permitted by law or executive order to be closed.

(d) If on the Closing Date any Selling Stockholder fails to sell the Firm Shares which such Selling Stockholder has agreed to sell on the Closing Date as set forth in Schedule II hereto, the Company agrees that it will sell or arrange for the sale of that number of shares of Common Stock to the Underwriters which represents Firm Shares which such Selling Stockholder has failed to so sell, as set forth in Schedule II hereto, or such lesser number as may be requested by the Representatives.

(e) In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company hereby grants an option to the several Underwriters to purchase the Option Shares at the price per share as set forth in the first paragraph of this Section 2. The option granted hereby may be exercised in whole or in part by giving written notice (i) at any time before the Closing Date and/or (ii) at any time thereafter within 30 days after the date of this Agreement, by you, as Representatives of the several Underwriters, to the Company setting forth the number of Option Shares as to which the several Underwriters are exercising the option and the time and date at which such certificates are to be delivered. The time and date at which certificates for Option Shares are to be delivered shall be determined by the Representatives but shall not be earlier than three nor later than 10 full business days after the exercise of such option, nor in any event prior to the Closing Date (such time and date being herein referred to as the “Option Closing Date”). If the date of exercise of the option is three or more days before the Closing Date, the notice of exercise shall set the Closing Date as the Option Closing Date. The option with respect to the Option Shares granted hereunder may be exercised only to cover over-allotments in the sale of the Firm Shares by the Underwriters. You, as Representatives of the several Underwriters, may cancel such option at any time prior to its expiration by giving written notice of such cancellation to the Company. To the extent, if any, that the option is exercised, payment for the Option Shares shall be made on the Option Closing Date in Federal (same day) funds drawn to the order of the Company for the Option Shares to be sold by it against delivery of certificates or book-entry credits therefor to the Representatives for the several accounts of the Underwriters.

OFFERING BY THE UNDERWRITERS.

It is understood that the several Underwriters are to make a public offering of the Firm Shares as soon as the Representatives deem it advisable to do so. The Firm Shares are to be initially offered to the public at the initial public offering price set forth in the Prospectus. The Representatives may from time to time thereafter change the public offering price and other selling terms.

It is further understood that you will act as the Representatives for the Underwriters in the offering and sale of the Shares in accordance with a Master Agreement Among Underwriters entered into by you and the several other Underwriters.

The Underwriters confirm that they have not distributed any Testing-the-Waters Writing on behalf of the Company other than those listed on Schedule VI hereto.

COVENANTS OF THE COMPANY AND THE SELLING STOCKHOLDERS.

(a) The Company covenants and agrees with the several Underwriters that:

(i) The Company will (A) prepare and timely file with the Commission under Rule 424(b) under the Act a Prospectus in a form approved by the Representatives containing information previously omitted at the time of effectiveness of the Registration Statement in reliance on Rules 430A, 430B or 430C under the Act, (B) not file any amendment to the Registration Statement or distribute an amendment or supplement to the General Disclosure Package or the Prospectus of which the Representatives shall not previously have been advised and furnished with a copy or to which the Representatives shall have reasonably objected in writing or which is not in compliance in all material respects with the Rules and Regulations and (C) file on a timely basis all reports and any definitive proxy or information statements required to be filed by the Company with the Commission subsequent to the date of the Prospectus and prior to the earlier of the termination of the offering of the Shares by the Underwriters pursuant to this Agreement or the termination of this Agreement.

(ii) The Company will (A) not make any offer relating to the Shares that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 under the Act) required to be filed by the Company with the Commission under Rule 433 under the Act unless the Representatives approve its use in writing prior to first use (each, a “Permitted Free Writing Prospectus”); provided that the prior written consent of the Representatives hereto shall be deemed to have been given in respect of the Issuer Free Writing Prospectus(es) included in Schedule IV hereto, (B) treat each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus, (C) comply with the requirements of Rules 164 and 433 under the Act applicable to any Issuer Free Writing Prospectus, including the requirements relating to timely filing with the Commission, legending and record keeping and (D) not take any action that would result in an Underwriter or the Company being required to file with the Commission pursuant to Rule 433(d) under the Act a free writing prospectus prepared by or on behalf of such Underwriter that such Underwriter otherwise would not have been required to file thereunder.

(iii) The Company will prepare a final term sheet (the “Final Term Sheet”) reflecting the final terms of the Shares, in form and substance satisfactory to the Representatives, and shall file such Final Term Sheet as an Issuer Free Writing Prospectus pursuant to Rule 433 under the Act prior to the close of business two business days after the date hereof; provided that the Company shall provide the Representatives with copies of any such Final Term Sheet a reasonable

amount of time prior to such proposed filing and will not use or file any such document to which the Representatives or counsel to the Underwriters shall reasonably object.

(iv) The Company will advise the Representatives promptly (A) when the Registration Statement or any post-effective amendment thereto shall have become effective, (B) of receipt of any comments from the Commission, (C) when any supplement to the Prospectus, any Issuer Free Writing Prospectus or any Testing-the-Waters Writing or any amendment to the Prospectus has been filed or distributed, (D) of any request of the Commission for amendment of the Registration Statement or for supplement to the General Disclosure Package or the Prospectus or for any additional information including, but not limited to, any request for information concerning any Testing-the-Waters Writing, and (E) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or any order preventing or suspending the use of any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus or any Testing-the-Waters Writing, or of the institution of any proceedings for that purpose or pursuant to Section 8A of the Act. The Company will use its best efforts to prevent the issuance of any such order and to obtain as soon as possible the lifting thereof, if issued.

(v) The Company will cooperate with the Representatives in endeavoring to qualify the Shares for sale under the securities laws of such jurisdictions as the Representatives may reasonably have designated in writing and will make such applications, file such documents, and furnish such information as may be reasonably required for that purpose, provided the Company shall not be required to qualify as a foreign corporation or to file a general consent to service of process in any jurisdiction where it is not now so qualified or required to file such a consent. The Company will, from time to time, prepare and file such statements, reports, and other documents, as are or may be required to continue such qualifications in effect for so long a period as the Representatives may reasonably request for distribution of the Shares.

(vi) The Company will deliver to, or upon the order of, the Representatives, from time to time, as many copies of any Preliminary Prospectus as the Representatives may reasonably request. The Company will deliver to, or upon the order of, the Representatives, from time to time, as many copies of any Issuer Free Writing Prospectus as the Representatives may reasonably request. The Company will deliver to, or upon the order of, the Representatives during the period when delivery of a Prospectus (or, in lieu thereof, the notice referred to under Rule 173(a) under the Act) (the “Prospectus Delivery Period”) is required under the Act, as many copies of the Prospectus in final form, or as thereafter amended or supplemented, as the Representatives may reasonably request. The Company will deliver to the Representatives at or before the Closing Date, four signed copies of the Registration Statement and all amendments thereto including all exhibits filed therewith, and will deliver to the Representatives such number of copies of the Registration Statement (including such number of copies of the exhibits filed therewith that may reasonably be requested), and of all amendments thereto, as the Representatives may reasonably request.

(vii) The Company will comply with the Act and the Rules and Regulations, and the Exchange Act, and the rules and regulations of the Commission thereunder, so as to permit the completion of the distribution of the Shares as contemplated in this Agreement and the

Prospectus so long as the offering and this agreement are not terminated. If during the period in which a prospectus (or, in lieu thereof, the notice referred to under Rule 173(a) under the Act) is required by law to be delivered by an Underwriter or dealer, any event shall occur as a result of which, in the judgment of the Company or in the reasonable opinion of the Underwriters, it becomes necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances existing at the time the Prospectus is delivered to a purchaser, not misleading, or, if it is necessary at any time to amend or supplement the Prospectus to comply with any law, the Company promptly will prepare and file with the Commission an appropriate amendment to the Registration Statement or supplement to the Prospectus so that the Prospectus as so amended or supplemented will not, in the light of the circumstances when it is so delivered, be misleading, or so that the Prospectus will comply with the law.

(viii) If the General Disclosure Package is being used to solicit offers to buy the Shares at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur as a result of which, in the judgment of the Company or in the reasonable opinion of the Underwriters, it becomes necessary to amend or supplement the General Disclosure Package in order to make the statements therein, in the light of the circumstances, not misleading, or to make the statements therein not conflict with the information contained in the Registration Statement then on file, or if it is necessary at any time to amend or supplement the General Disclosure Package to comply with any law, the Company promptly will prepare, file with the Commission (if required) and furnish to the Underwriters and any dealers an appropriate amendment or supplement to the General Disclosure Package so that the General Disclosure Package as so amended or supplemented will not, in the light of the circumstances, be misleading or conflict with the Registration Statement then on file, or so that the General Disclosure Package will comply with law.

(ix) The Company will make generally available to its security holders, as soon as it is practicable to do so, but in any event not later than 15 months after the effective date of the Registration Statement, an earnings statement (which need not be audited) in reasonable detail, covering a period of at least 12 consecutive months beginning after the effective date of the Registration Statement, which earnings statement shall satisfy the requirements of Section 11(a) of the Act and Rule 158 under the Act and will advise you in writing when such statement has been so made available.

(x) Prior to the Closing Date, the Company will furnish to the Underwriters, as soon as they have been prepared by or are available to the Company, a copy of any unaudited interim financial statements of the Company for any period subsequent to the period covered by the most recent financial statements appearing in the Registration Statement, the General Disclosure Package and the Prospectus; provided that the reports and information described in this subsection (x) shall only be provided to the Underwriters if such reports and information are not available on the Electronic Data Gathering Analysis and Retrieval (EDGAR) system or the Company’s website.

(xi) For a period of 180 days after the date of the Prospectus, the Company will not (A) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or

dispose of, directly or indirectly, or file with the Commission a registration statement under the Act relating to, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock (other than pursuant to equity incentive plans as in existence on the date of this Agreement or pursuant to the exercise or conversion of warrants or convertible securities outstanding as of the date of this Agreement), or publicly disclose the intention to make any such offer, sale, pledge, disposition or filing, or (B) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock or any such other securities, whether any such transaction described in clause (A) or (B) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise, without the prior written consent of the Representatives. Notwithstanding the foregoing, if (1) during the last 17 days of the 180-day restricted period, the Company issues an earnings release or material news or a material event relating to the Company occurs; or (2) prior to the expiration of the 180-day restricted period, the Company announces that it will release earnings results during the 16-day period following the last day of the 180-day restricted period, then in each case the restrictions imposed by this Agreement shall continue to apply until the expiration of the 18-day period beginning on the date of the release of the earnings results or the occurrence of material news or a material event relating to the Company, as the case may be, unless the Representatives waive, in writing, such extension.

(xii) The Company will use its best efforts to list the Shares, subject to notice of issuance, on the Nasdaq Stock Market.

(xiii) The Company has caused each officer and director of the Company and the additional securityholders of the Company specified on Schedule VII to furnish to you, on or prior to the date of this agreement, a letter or letters, substantially in the form attached hereto as Exhibit A (the “Lockup Agreement”).

(xiv) If the Representatives agree to release or waive the restrictions set forth in a Lockup Agreement for an officer or director of the Company and the Representatives provide the Company with notice of the impending release or waiver at least three business days before the effective date of the release or waiver, the Company agrees to announce the impending release or waiver by a press release substantially in the form of Exhibit B hereto through a major news service at least two business days before the effective date of the release or waiver.

(xv) The Company shall apply the net proceeds of its sale of the Shares as set forth in the Registration Statement, General Disclosure Package and the Prospectus and shall file such reports with the Commission with respect to the sale of the Shares and the application of the proceeds therefrom as may be required in accordance with Rule 463 under the Act.

(xvi) The Company shall not invest, or otherwise use the proceeds received by the Company from its sale of the Shares in such a manner as would require the Company or any of the Subsidiaries to register as an investment company under the 1940 Act.

(xvii) The Company will maintain a transfer agent and, if necessary under the jurisdiction of incorporation of the Company, a registrar for the Common Stock.

(xviii) The Company will not take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, the stabilization or manipulation of the price of any securities of the Company.

(xix) The Company will promptly notify the Representatives if the Company ceases to be an Emerging Growth Company at any time prior to the later of (a) completion of the distribution of the Shares within the meaning of the Act and (b) completion of the restricted period referred to in Section 4(a)(xi) hereof.

(b) Each of the Selling Stockholders covenants and agrees with the several Underwriters that:

(i) Such Selling Stockholder has executed and delivered the Lockup Agreement and such Lockup Agreement remains in full force and effect.

(ii) In order to document the Underwriters’ compliance with the reporting and withholding obligations of U.S. Treasury Regulations, with respect to the transactions herein contemplated, each of the Selling Stockholders agrees to deliver to you prior to or at the Closing Date a properly completed and executed applicable United States Treasury Department Form W-8 or W-9 (or other applicable form or statement specified by Treasury Department regulations in lieu thereof).

(iii) Such Selling Stockholder will not take, directly or indirectly, any action designed to cause or result in, or that has constituted or might reasonably be expected to constitute, the stabilization or manipulation of the price of any securities of the Company.

(iv) Such Selling Stockholder agrees that it will not prepare or have prepared on its behalf or use or refer to, any “free writing prospectus” (as defined in Rule 405 under the Act), and agrees that it will not distribute any written materials in connection with the offer or sale of the Shares.

(v) During the Prospectus Delivery Period, such Selling Stockholder will advise the Representatives promptly, and will confirm such advice in writing to the Representatives, of any change in the information relating to such Selling Stockholder in the Registration Statement, the Prospectus or any document comprising the General Disclosure Package.

COSTS AND EXPENSES.

The Company will pay all costs, expenses and fees incident to the performance of the obligations of the Sellers under this Agreement, including, without limiting the generality of the foregoing, the following: accounting fees of the Company; the fees and disbursements of counsel for the Company and the Selling Stockholders; any roadshow expenses; the cost of printing and

Any transfer taxes imposed on the sale of the Shares to the several Underwriters will be paid by the Sellers pro rata. The Sellers shall not, however, be required to pay for any of the Underwriters’ expenses (other than those related to qualification under FINRA regulation and State securities or Blue Sky laws) except that, if this Agreement shall not be consummated because the conditions in Section 6 hereof are not satisfied, or because this Agreement is terminated by the Representatives pursuant to Section 11 hereof, or by reason of any failure, refusal or inability on the part of the Company or the Selling Stockholders to perform any undertaking or satisfy any condition of this Agreement or to comply with any of the terms hereof on their part to be performed, unless such failure, refusal or inability is due primarily to the default or omission of any Underwriter, the Company shall reimburse the several Underwriters for reasonable out-of-pocket expenses, including reasonable fees and disbursements of counsel, reasonably incurred in connection with investigating, marketing and proposing to market the Shares or in contemplation of performing their obligations hereunder; but the Company and the Selling Stockholders shall not in any event be liable to any of the several Underwriters for damages on account of loss of anticipated profits from the sale by them of the Shares.

(i) to indemnify and hold harmless each Underwriter, the directors and officers of each Underwriter and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which such Underwriter or any such controlling person may become subject under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (A) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, any Preliminary Prospectus, the General Disclosure Package, any Issuer Free Writing Prospectus, the Prospectus, any Testing-the-Waters Writing or any amendment or supplement thereto, (B) with respect to the Registration Statement or any amendment or supplement thereto, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or (C) with respect to the Preliminary Prospectus, the General Disclosure Package, any Issuer Free Writing Prospectus, the Prospectus, any Testing-the-Waters Writing or any amendment or supplement thereto, the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made; provided, however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement, or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, the General Disclosure Package, any Issuer Free Writing Prospectus, the Prospectus, any Testing-the-Waters Writing, or any amendment or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by or through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 13 herein; and

(ii) to reimburse each Underwriter, each Underwriter’s directors and officers, and each such controlling person upon demand for any legal or other out-of-pocket expenses reasonably incurred by such Underwriter or such controlling person in connection with investigating or defending any such loss, claim, damage or liability, action or proceeding or in responding to a subpoena or governmental inquiry related to the offering of the Shares, whether or not such Underwriter or controlling person is a party to any action or proceeding. In the event that it is finally judicially determined that the Underwriters were not entitled to receive payments for legal and other expenses pursuant to this subparagraph, the Underwriters will promptly return all sums that had been advanced pursuant hereto.

(b) Each Selling Stockholder severally and not jointly, in proportion to the number of Shares to be sold by such Selling Stockholder hereunder agrees to indemnify the Underwriters, each Underwriter’s directors and officers, and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which such Underwriter or controlling person may become subject

under the Act or otherwise to the same extent as indemnity is provided by the Company pursuant to Section 8(a) above, provided however, that each Selling Stockholder will be liable in each case to the extent, but only to the extent, that any such untrue statement or alleged untrue statement or omission or alleged omission has been made in reliance upon and in conformity with the Selling Stockholder Information. This indemnity obligation will be in addition to any liability which such Selling Stockholder may otherwise have.

(c) Each Underwriter severally and not jointly will indemnify and hold harmless the Company, each of its directors, each of its officers who have signed the Registration Statement and each person, if any, who controls the Company within the meaning of the Act, against any losses, claims, damages or liabilities to which the Company or any such director, officer or controlling person may become subject under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, any Preliminary Prospectus, the General Disclosure Package, any Issuer Free Writing Prospectus, the Prospectus, any Testing-the-Waters Writing or any amendment or supplement thereto, or (ii) the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances under which they were made; and will reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer or controlling person in connection with investigating or defending any such loss, claim, damage, liability, action or proceeding; provided, however, that each Underwriter will be liable in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission has been made in the Registration Statement, any Preliminary Prospectus, the General Disclosure Package, any Issuer Free Writing Prospectus, the Prospectus, any Testing-the-Waters Writing or any amendment or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by or through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 13 herein. This indemnity obligation will be in addition to any liability which such Underwriter may otherwise have.

(d) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to this Section 8, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing. No indemnification provided for in Section 8(a), (b) or (c) shall be available to any party who shall fail to give notice as provided in this Section 8(d) if the party to whom notice was not given was unaware of the proceeding to which such notice would have related and was materially prejudiced by the failure to give such notice, but the failure to give such notice shall not relieve the indemnifying party or parties from any liability which it or they may have to the indemnified party for contribution or otherwise than on account of the provisions of Section 8(a), (b) or (c). In case any such proceeding shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel

reasonably satisfactory to such indemnified party and shall pay as incurred the reasonable fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel at its own expense. Notwithstanding the foregoing, the indemnifying party shall pay as incurred (or within 30 days of presentation) the reasonable fees and expenses of the counsel retained by the indemnified party in the event (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or (iii) the indemnifying party shall have failed to assume the defense and employ counsel acceptable to the indemnified party within a reasonable period of time after notice of commencement of the action. 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 reasonable fees and expenses of more than one separate firm for all such indemnified parties. Such firm shall be designated in writing by you in the case of parties indemnified pursuant to Section 8(a) or (b) and by the Company in the case of parties indemnified pursuant to Section 8(c). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. In addition, the indemnifying party will not, without the prior written consent of the indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding of which indemnification may be sought hereunder (whether or not any indemnified party is an actual or potential party to such claim, action or proceeding) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action or proceeding.

(e) To the extent the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under Section 8(a), (b) or (c) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) 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 Underwriters on the other from the offering of the Shares. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company and the Selling Stockholders on the one hand and the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions or proceedings 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 shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company and the Selling Stockholders bear to the total underwriting discounts and commissions received by the Underwriters, 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, 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 or the Selling Stockholders on the one hand or the Underwriters on the other 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 Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 8(e) were 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 account of the equitable considerations referred to above in this Section 8(e). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to above in this Section 8(e) shall be deemed to include 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 8(e), (i) no Underwriter shall be required to contribute any amount in excess of the underwriting discounts and commissions applicable to the Shares purchased by such Underwriter, (ii) 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, and (iii) no Selling Stockholder shall be required to contribute any amount in excess of the proceeds received by such Selling Stockholder from the Underwriters in the offering. The Underwriters’ obligations in this Section 8(e) to contribute are several in proportion to their respective underwriting obligations and not joint. Notwithstanding anything to the contrary in this Agreement, the liability of each Selling Stockholder under the indemnity and contribution agreements contained in this Section 8, and in respect of any claim arising out of a breach of the representations and warranties of such Selling Stockholder contained in Section 1(b)(iv), shall be limited to an amount equal to the proceeds received by such Selling Stockholder from the Underwriters in the offering.

(f) In any proceeding relating to the Registration Statement, any Preliminary Prospectus, the General Disclosure Package, any Issuer Free Writing Prospectus, the Prospectus, any Testing-the-Waters Writing or any supplement or amendment thereto, each party against whom contribution may be sought under this Section 8 hereby consents to the jurisdiction of any court having jurisdiction over any other contributing party, agrees that process issuing from such court may be served upon it by any other contributing party and consents to the service of such process and agrees that any other contributing party may join it as an additional defendant in any such proceeding in which such other contributing party is a party.

(g) Any losses, claims, damages, liabilities or expenses for which an indemnified party is entitled to indemnification or contribution under this Section 8 shall be paid by the indemnifying party to the indemnified party as such losses, claims, damages, liabilities or expenses are incurred. The indemnity and contribution agreements contained in this Section 8 and the representations and warranties of the Company set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Underwriter, its directors and officers or any person controlling any Underwriter, the Company, its

directors or officers or any persons controlling the Company, (ii) delivery and acceptance of any Shares and payment therefor hereunder, and (iii) any termination of this Agreement. A successor to any Underwriter, its directors and officers or any person controlling any Underwriter, or to the Company, its directors or officers, or any person controlling the Company, shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section 8.

(h) The obligations of the Company and the Selling Stockholders under this Section 8 shall be in addition to any liability which the Company and the Selling Stockholders may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the Act or the Exchange Act.

DEFAULT BY UNDERWRITERS.

If on the Closing Date or the Option Closing Date, as the case may be, any Underwriter shall fail to purchase and pay for the portion of the Shares which such Underwriter has agreed to purchase and pay for on such date (otherwise than by reason of any default on the part of the Company or a Selling Stockholder), you, as Representatives of the Underwriters, shall use your reasonable efforts to procure within 36 hours thereafter one or more of the other Underwriters, or any others, to purchase from the Company and the Selling Stockholders such amounts as may be agreed upon and upon the terms set forth herein, the Shares which the defaulting Underwriter or Underwriters failed to purchase. If during such 36 hours you, as such Representatives, shall not have procured such other Underwriters, or any others, to purchase the Shares agreed to be purchased by the defaulting Underwriter or Underwriters, then (a) if the aggregate number of Shares with respect to which such default shall occur does not exceed 10% of the Shares to be purchased on the Closing Date or the Option Closing Date, as the case may be, the other Underwriters shall be obligated, severally, in proportion to the respective numbers of Shares which they are obligated to purchase hereunder, to purchase the Shares which such defaulting Underwriter or Underwriters failed to purchase, (b) if the aggregate number of Shares with respect to which such default shall occur exceeds 10% of the Shares to be purchased on the Closing Date, the Company and the Selling Stockholders or you as the Representatives of the Underwriters will have the right, by written notice given within the next 36-hour period to the parties to this Agreement, to terminate this Agreement without liability on the part of the non-defaulting Underwriters or of the Company or of the Selling Stockholders except to the extent provided in Sections 5 and 8 hereof, and (c) if the aggregate number of Shares with respect to which such default shall occur exceeds 10% of the Shares to be purchased on the Option Closing Date, the Company or you as the Representatives of the Underwriters will have the right, by written notice given within the next 36-hour period to the parties to this Agreement, to terminate this Agreement without liability on the part of the non-defaulting Underwriters or of the Company except to the extent provided in Sections 5 and 8 hereof. In the event of a default by any Underwriter or Underwriters, as set forth in this Section 9, the Closing Date or Option Closing Date, as the case may be, may be postponed for such period, not exceeding seven days, as you, as Representatives, may determine in order that the required changes in the Registration Statement, the General Disclosure Package or in the Prospectus or in any other documents or arrangements may be effected. The term “Underwriter” includes any person substituted for a defaulting Underwriter. Any action taken under this Section 9 shall not relieve any

defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.
