With respect to each Plan subject to Title IV of ERISA, (a) no “reportable event” (as defined in ERISA) has occurred or is reasonably expected to occur, (b) no “accumulated funding deficiency” (within the meaning of Section 302 of ERISA or Section 412 of the Code), whether or not waived, has occurred or is reasonably expected to occur, (c) the fair market value of the assets under each Plan exceeds the present value of all benefits accrued under such Plan (determined based on those assumptions used to fund such Plan), and (d) neither the Company nor any ERISA Affiliate has incurred, or reasonably expects to incur, any liability under (i) Title IV of ERISA (other than contributions to the Plan or premiums to the Pension Benefit Guaranty Corporation in the ordinary course and without default) in respect of a Plan (including a “multiemployer plan” within the meaning of Section 4001(c)(3) of ERISA), or (ii) Sections 412 or 4971 of the Code, except, in each case, as would not result in a Material Adverse Effect. Each Plan that is intended to be qualified under Section 401(a) of the Code is so qualified, and nothing has occurred or is expected to occur, whether by action or by failure to act, which would cause the loss of such qualification.

(jj) No hazardous substances, hazardous wastes, pollutants or contaminants (i) have been released, deposited or disposed of in, on or under any properties during the period in which the Company or any Subsidiary has owned, leased, managed, controlled or operated such properties; or (ii) have been released, deposited or disposed of by or on behalf of the Company in, on or under any such properties, in the case of each of clauses (i) and (ii) in violation of any applicable law, ordinance, rule, regulation, order, judgment, decree or permit or which would require remedial action under any applicable law, ordinance, rule, regulation, order, judgment, decree or permit, except for any release, violation or remedial action (other than remedial actions of the type routinely carried out at facilities of like character to those operated by the Company and its Subsidiaries) which would not have, individually or in the aggregate with all such releases, violations or remedial actions, a Material Adverse Effect.

(ll) The Company has obtained for the benefit of the Underwriters the agreement (a “Lock-Up Agreement”), in the form requested by the Underwriters, of those individuals set forth on Annex II hereto.

(mm) The Company has established and maintains and evaluates “disclosure controls and procedures” (as such term is defined in Rule 13a-15(e) under the Exchange Act; such disclosure controls and procedures are designed to ensure that material information relating to the Company, and its Subsidiaries, required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is made known to the Company’s Chief Executive Officer and its Chief Financial Officer by others within those entities, and such disclosure controls and procedures are effective in providing reasonable assurance that material information relating to the Company and its Subsidiaries is made known to such persons, including during the period when the Company prepares its periodic reports to be filed with or furnished to the Commission. The Company does not have knowledge of (a) except as disclosed in the Registration Statement, Disclosure Package and Prospectus, any material weaknesses in its internal controls over financial reporting or (b) any fraud, whether or not material, that involves management or other employees who have a significant role in the Company’s internal controls.

Company and the Subsidiaries and affiliates have conducted their businesses in compliance with applicable anti-corruption laws and have instituted and maintain and will continue to maintain policies and procedures designed to promote and achieve compliance with such laws and with the representation and warranty contained herein.

(qq) The Company and the Subsidiaries own or have a valid right to access and use all computer systems, networks, hardware, software, databases, websites, and equipment used to process, store, maintain and operate data, information, and functions used in connection with the business of the Company and the Subsidiaries (the “Company IT Systems”), except as would not, individually or in the aggregate, have a Material Adverse Effect. The Company IT Systems are adequate for, and operate and perform in all material respects as required in connection with, the operation of the business of the Company and the Subsidiaries as currently conducted.

(ss) There are no costs or liabilities associated with Environmental Laws (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties) which would, individually or in the aggregate, have a Material Adverse Effect on the Company and the Subsidiaries, taken as a whole.

(tt) The operations of the Company and the Subsidiaries are and have been conducted at all times in material compliance with all applicable financial recordkeeping and reporting requirements, including those of the Bank Secrecy Act, as amended by Title III of the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (USA PATRIOT Act), and the applicable anti-money laundering statutes of jurisdictions where the Company and its subsidiaries conduct business, the rules and regulations thereunder and any related or similar rules, regulations or guidelines, issued, administered or enforced by any governmental agency (collectively, the “Money Laundering Laws”), and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Company or any of its subsidiaries with respect to the Money Laundering Laws is pending or, to the best knowledge of the Company, threatened.

(uu) None of the Company, any of the Subsidiaries, or, to the knowledge of the Company, any officer, director, agent, employee, affiliate or representative of the Company or any of its subsidiaries who is an individual or entity (“Person”) (i) has violated or is in violation of any provision laws and regulations imposing U.S. economic sanctions measures, including, but not limited to, the International Emergency Economic Powers Act, the Trading with the Enemy Act, the United Nations Participation Act, and the Syria Accountability and Lebanese Sovereignty Act, all as amended, and any executive order, directive, or regulation pursuant to the authority of any of the foregoing, including the regulations of the United States Treasury Department set forth under 31 CFR, Subtitle B, Chapter V, as amended, or any orders or licenses issued thereunder or (ii) is currently the subject or target of any sanctions administered or enforced by the United States Government, including, without limitation, the U.S. Department of the Treasury’s Office of Foreign Assets Control (“OFAC”), the United Nations Security Council (“UNSC”), the European Union, Her Majesty’s Treasury (“HMT”), or other relevant sanctions authority (collectively, “Sanctions”), nor is the Company located, organized or resident in a country or territory that is the subject of Sanctions; and the Company will not directly or indirectly use the proceeds of the sale of the Shares, or lend, contribute or otherwise make available such proceeds to any subsidiaries, joint venture partners or other Person, to fund any activities of or business with any Person, or in any country or territory, that, at the time of such funding, is the subject of Sanctions or in any other manner that will result in a violation by any Person (including any Person participating in the transaction, whether as underwriter, advisor, investor or otherwise) of Sanctions.

(vv) Except as described in the Sale Preliminary Prospectus, the Company has not sold, issued or distributed any shares of Common Stock during the six-month period preceding the date hereof, including any sales pursuant to Rule 144A under, or Regulation D or S of, the Act, other than shares issued pursuant to employee benefit plans, qualified stock option plans or other employee compensation plans or pursuant to outstanding options, rights or warrants.

If the Company has elected to rely on Rule 430A under the Act relating to the Shares, the Company will prepare and file a Prospectus containing the information omitted therefrom pursuant to Rule 430A with the Commission within the time period required by, and otherwise in accordance with the provisions of, Rules 424(b) and 430A, if applicable. If the Company has elected to rely upon Rule 462(b) of the Rules and Regulations to increase the size of the offering registered under the Act relating to the Shares, the Company will prepare and file a Rule 462(b) Registration Statement with respect to such increase with the Commission within the time period required by, and otherwise in accordance with the provisions of, Rule 462(b). During the Distribution Period, the Company will give the Underwriters notice of its intention to file or prepare any amendment to the Registration Statement (including any filing under Rule 424(b)), or any amendment, supplement or revision to the Prospectus or the Sale Preliminary Prospectus, will furnish the Underwriters with copies of any such documents a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document to which the Underwriters or counsel to the Underwriters shall reasonably object.

(b) The Company will advise the Underwriters, promptly after the Company receives notice or obtains knowledge thereof, of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement, of the suspension of the qualification of the Shares for offering or sale in any jurisdiction or quoted for trading on The NASDAQ Capital Market, or of the initiation or, to the Company’s knowledge, threatening of any proceeding for any such purpose; and the Company will use its best efforts to prevent the issuance of any stop order or suspension or to obtain its withdrawal if such a stop order or suspension should be issued.

If, during the Distribution Period, the Sale Preliminary Prospectus is being used to solicit offers to purchase Shares at a time when the Prospectus is not yet available and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Sale Preliminary Prospectus in writing in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Sale Preliminary Prospectus to comply with applicable law, the Company shall promptly prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to any dealer upon request, either amendments or supplements to the Sale Preliminary Prospectus so that the statements in the Sale Preliminary Prospectus as so amended or supplemented will not, in the light of the circumstances when the Sale Preliminary Prospectus is delivered to a prospective purchaser, be misleading or so that the Sale Preliminary Prospectus, as amended or supplemented, will comply with applicable law. If during the Distribution Period any event occurs, or fails to occur, as a result of which, in the judgment of the Company or the Selling Stockholders or in the opinion of the Underwriters, (i) the Prospectus would include an untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances then existing, not misleading, or (ii) it becomes necessary to amend the Registration Statement or supplement the Prospectus to comply with the Act, then the Company will promptly notify the Underwriters and will prepare and file with the Commission, and furnish at its own expense to the Underwriters, an 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 Act.

(d) The Company shall cooperate with the Underwriters and counsel for the Underwriters in endeavoring to qualify the Shares for offering and sale under (or obtain exemptions from the application of) the applicable securities laws of such states and other jurisdictions of the United States as the Underwriters may reasonably designate; provided that no such qualification shall be required in any jurisdiction where, as a result thereof, the Company would become subject to service of general process, to qualification to do business as a foreign entity, to registration as a securities dealer or to taxation as a foreign corporation. In each jurisdiction in which the Shares have been so qualified, the Company will file such statements and reports as may be required to be filed by it by the laws of such jurisdiction to continue such qualification in effect so long as required for the distribution of such securities.

(e) The Company shall furnish to each Underwriter, without charge, copies of (i) the Registration Statement as originally filed (including all exhibits filed therewith), each amendment thereto (without exhibits) and (ii) each of the Preliminary Prospectuses, the Prospectus and all amendments and supplements thereto, in each case as soon as available and, with respect to the documents in clause (ii), in such quantities as the Underwriters may reasonably request.

(f) For a period of two years commencing with the date hereof, the Company will furnish to the Underwriters copies of all documents, reports and other information furnished by the Company to the holders of its Common Stock generally except, in each case, if available on the Commission’s Electronic Data Gathering, Analysis and Retrieval System.

(g) The Company shall make generally available to holders of the Common Stock as soon as practicable, but in any event not later than 15 months after the end of the Company’s current fiscal quarter, an earnings statement (which need not be audited) covering a period of at least 12 months beginning after the date on which the Prospectus is filed pursuant to Rule 424(b) under the Act that satisfies the provisions of Section 11(a) of the Act and Rule 158 thereunder.

(h) The Company shall apply the net proceeds received by it from the sale of the Shares for the purposes set forth in the Registration Statement, Disclosure Package and Prospectus under the caption “Use of Proceeds” therein.

(i) The Company and the Selling Stockholders shall not take, directly or indirectly, prior to the termination of the offering contemplated by this Agreement, any action designed to or which might reasonably be expected to cause or result in the stabilization or manipulation of the price of the Common Stock to facilitate the sale or resale of the Shares.

(j) For so long as the shares of Common Stock sold in the offering contemplated by this Agreement are listed on The NASDAQ Capital Market or a comparable securities exchange or market, the Company shall engage and maintain a registrar and transfer agent for the Common Stock.

8. Indemnification and Contribution.

(a) The Company agrees to indemnify and hold each Underwriter, its officers and employees, and each person, if any, who controls any Underwriter within the meaning of the Act, harmless against any losses, claims, damages, liabilities or expenses (“Losses”), to which such Underwriter may become subject under the Act or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Company), insofar as such Losses (or actions in respect thereof) arise out of or are based upon (i) an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereto, or 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 (ii) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus or the Prospectus, or any amendment or supplement thereto, or the omission or alleged omission therefrom of 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 the Company will not be liable in any such case to the extent that any such Losses arise out of or are based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by the Underwriters, specifically for use in the preparation thereof, it being understood and agreed that the only such information furnished by an Underwriter consists of the information described as such in Section 11 hereof.

(b) Each Selling Stockholder agrees to indemnify and hold harmless each Underwriter, its officers and employees, and each person, if any, who controls any Underwriter within the meaning of the Act, to the extent and in the manner set forth in Section 8(a); provided that such Selling Stockholder shall be liable 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 Disclosure Package or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with the Selling Stockholder Information.

(c) Each Underwriter agrees, severally and not jointly, to indemnify and hold the Company, its directors, officers and employees, and each person, if any, who controls the Company within the meaning of the Act, and each Selling Stockholder, its directors, officers and employees, and each person, if any, who controls the Selling Stockholder within the meaning of the Act, harmless from and against any Losses to which any such person may become subject, under the Act or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Underwriter), insofar as such Losses (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto, or arise out of or are based upon 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 each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any Preliminary Prospectus or the Prospectus in reliance upon and in conformity with written information furnished to the Company by the Underwriter specifically for use in the preparation thereof, it being understood and agreed upon that the only such information furnished by an Underwriter consists of the information described as such in Section 12 hereof.

(d) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party in writing of the commencement thereof; but the failure to so notify the indemnifying party shall not relieve the indemnifying party from any liability that it may have to any indemnified party (i) unless and to the extent the failure results in the forfeiture by the indemnifying party of substantial rights and defenses, (ii) for contribution or (iii) otherwise than under this Section 8. In case any such action 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 in, and, to the extent that it shall elect, jointly with any other indemnifying party similarly notified, by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that a conflict may arise between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties.

After notice from the indemnifying party to such indemnified party of the indemnifying party’s election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under this subsection for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the reasonable expenses of more than one separate counsel (together with local counsel), approved by the indemnifying party (an Underwriter in the case of subsection (b) above) representing the indemnified parties who are parties to such action); (ii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of the action; or (iii) the indemnifying party has authorized the employment of counsel for the indemnified party at the expense of the indemnifying party, in each of which case the reasonable fees and expenses of counsel shall be at the expense of the indemnifying party.

(e) The indemnifying party under this Section 8 shall not be liable for any settlement of any proceeding effected without its written consent, which consent shall not be unreasonably withheld, but if settled with such consent or if there be a final non-appealable judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party against any Losses by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified party (which consent shall not be unreasonably withheld), effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity was or could have been sought hereunder by such indemnified party, unless such settlement, compromise or consent includes (x) an unconditional release of such indemnified party from all liability on claims that are the subject matter of such action, suit or proceeding and (y) does not include a statement as to an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(f) If the indemnification provided for in this Section 8 is unavailable or insufficient to hold an indemnified party harmless under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the Losses referred to in subsection (a) or (b) above (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 Underwriters, on the other hand, from the offering of the Shares, or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, then 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 hand, in connection with the statements or omissions that resulted in such Losses, 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 hand, shall be deemed to be in the same respective 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 Underwriter. 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 or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue 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 subsection (f) were to be determined by pro rata allocation or by any other method of allocation which does not take account the equitable considerations referred to in the first paragraph of this subsection (f). The amount paid by an indemnified party as a result of the Losses referred to in the first paragraph of this subsection (f) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending against any action or claim which is the subject of this subsection (f). Notwithstanding the provisions of this subsection (f), no Underwriter shall be required to contribute any amount in excess of the underwriting discounts applicable to the Shares purchased by such Underwriter. 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.

(g) The obligations of the Company under this Section 8 shall be in addition to any liability which the Company may otherwise have, including liability for Losses incurred by the Underwriters, its officers and employees that arise out of or are based in whole or in part upon (i) any inaccuracy in the representations and warranties of the Company contained herein or (ii) the failure of the Company to perform its obligations hereunder or under law and shall extend, on the same terms and conditions, to each person, if any, who controls an Underwriter within the meaning of the Act. The obligations of the Selling Stockholders under this Section 8 shall be in addition to any liability which each Selling Stockholder may otherwise have, including liability for Losses incurred by the Underwriters, its officers and employees that arise out of or are based in whole or in part upon (i) any inaccuracy in the representations and warranties of such Selling Stockholder contained herein or (ii) the failure of such Selling Stockholder to perform its obligations hereunder or under law and shall extend, on the same terms and conditions, to each person, if any, who controls an Underwriter within the meaning of the Act. The obligations of each Underwriter under this Section 8 shall be in addition to any liability that such Underwriter may otherwise have and shall extend, upon the same terms and conditions, to each director of the Company, to each officer of the Company who has signed the Registration Statement, to each person, if any, who controls the Company within the meaning of the Act and to each person, if any, who controls a Selling Stockholder within the meaning of the Act.

(h) Any Losses 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 are incurred, but in all cases, no later than thirty (30) days after receipt of an invoice by the indemnifying party.

(i) The parties to this Agreement hereby acknowledge that they are sophisticated business persons and were represented by counsel during the negotiations regarding the provisions hereof including, without limitation, the provisions of this Section 8, and are fully informed regarding said provisions. They further acknowledge that the provisions of this Section 8 fairly allocate the risks in the light of the ability of the parties to investigate the Company and its business in order to assure that adequate disclosure is made in the Registration Statement and Prospectus as required by the Act and the Exchange Act.

9. Representations and Agreements to Survive Delivery.

All representations, warranties and agreements of the Company and the Selling Stockholders herein or in certificates delivered pursuant hereto, and the agreements of the Company, each Selling Stockholder and each Underwriter contained in Section 8 hereof, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of such Underwriter or any controlling person thereof, the Company or any of its officers, directors or controlling persons or any Selling Stockholder or any of its officers, directors or controlling persons and shall survive delivery of, and payment for, the Shares to and by the Underwriter hereunder and any termination of this Agreement. A successor to any Underwriter, to the Company or to any Selling Stockholder, and their respective directors, officers, and controlling persons shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in Section 8.

10. Termination.

(a) The Underwriters shall have the right to terminate this Agreement, by notice as hereinafter specified, at any time at or prior to the Closing Date or, in the case of the Option Shares, prior to the applicable Option Closing Date (i) if there shall have occurred a Material Adverse Change (regardless of whether any loss associated with such Material Adverse Change shall have been insured) or development involving a prospective Material Adverse Change that, in the judgment of the Underwriters, makes it impracticable or inadvisable to market the Shares in the manner and on the terms described in the Prospectus or to enforce contracts for the sale of the Shares; (ii) if there has occurred an outbreak or escalation of hostilities between the United States and any foreign power, an outbreak or escalation of any insurrection or armed conflict involving the United States, or any other calamity or crisis, or material adverse change or development in political, financial or economic conditions having an effect on the U.S. financial markets that, in the judgment of the Underwriters, makes it impracticable or inadvisable to market the Shares in the manner and on the terms described in the Prospectus or to enforce contracts for the sale of the Shares; or (iii) if trading in the Common Stock has been suspended or limited by the Commission or The NASDAQ Capital Market, or if trading in securities generally on either the New York Stock Exchange or The NASDAQ Stock Market has been suspended or limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices for securities have been required, by The NASDAQ Capital Market or by order of the Commission or any other governmental authority, or FINRA; (iv) if a general banking moratorium has been declared by federal, Delaware or New York authorities; or (v) if there has occurred a material disruption in commercial banking or securities settlement or clearance services in the United States.

(b) If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Company to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement for reasons other than the occurrence of one or more events contemplated by Section 10(a)(ii), (iv) or (v), the Company will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

(c) If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of a Selling Stockholder to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason such Selling Stockholder shall be unable to perform its obligations under this Agreement, such Selling Stockholder will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

11. Defaulting Underwriters.

If, on the Closing Date or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule A bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Representative may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Shares that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 11 by an amount in excess of one-ninth of such number of Shares without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Shares to be purchased on such date, and arrangements satisfactory to the Representative and the Company for the purchase of such Firm Shares are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter, any Selling Stockholder or the Company. In any such case either (i) the Representative or (ii) the Company and the Selling Stockholders shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Sale Preliminary Prospectus, in the Prospectus or in any other documents or arrangements may be effected. If, on an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Option Shares and the aggregate number of Option Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Shares to be purchased on such Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Option Shares to be sold on such Option Closing Date or (ii) purchase not less than the number of Option Shares that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

12. Defaulting Selling Stockholder.

If, on the Closing Date, a Selling Stockholder shall fail to sell and deliver the number of Selling Stockholder Shares which such Selling Stockholder is obligated to sell hereunder, and the Company does not exercise the right hereby granted to increase the number of Company Firm Shares to be sold by it hereunder to the total number of Shares to be sold by the Company and such Selling Stockholder hereunder, then the Underwriters may, at option of the Representative, by notice from the Representative to the Company, either (i) terminate this Agreement without any liability on the fault of any non-defaulting party except that the provisions of Sections 1, 6, 8, 9 and 16 shall remain in full force and effect or (ii) elect to purchase the Shares which the Company and any non-defaulting Selling Stockholder have agreed to sell hereunder. No action taken pursuant to this Section 12 shall relieve such Selling Stockholder from liability, if any, in respect of such default. In the event of a default by any Selling Stockholder as referred to in this Section 12, each of the Representative and the Company shall have the right to postpone the Closing Date for a period not exceeding seven (7) days in order to effect any required change in the Registration Statement, the Disclosure Package or the Prospectus or in any other documents or arrangements.

13. Information Furnished by Underwriter.

The Company hereby acknowledges that the only information that the Underwriters have furnished to the Company expressly for use in the Registration Statement, any Preliminary Prospectus or the Prospectus (or any amendment or supplement thereto) are the statements set forth in the first, second, third and fourth sentences in the first paragraph under the heading "Underwriting—Commissions and Discounts" and the statements in the first, second, third and fourth bullet points in the first paragraph under the heading “Underwriting—Price Stabilization, Short Positions and Penalty Bids”, in each case contained in the Prospectus; and the Underwriters confirm that such statements are correct.
