8. Indemnification and Contribution.

(a) Indemnification by the Company. Subject to the limitations in this paragraph below, the Company agrees to indemnify and hold harmless you and each other Underwriter, the directors, officers, employees, and agents of each Underwriter, and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages, liabilities, and expenses, including reasonable costs of investigation and attorneys' fees and expenses (collectively, "Damages") arising out of or based upon (a) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Commitment Prospectus, or the Prospectus, or in any amendment or supplement thereto, any Issuer Free Writing Prospectus or any "issuer information" filed or required to be filed pursuant to Rule 433(d) under the Securities Act, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in light of the circumstances under which they were made) not misleading, except to the extent that any such Damages arise out of or are based upon an untrue statement or omission or alleged untrue statement or omission that has been made therein or omitted therefrom in reliance upon and in conformity with the information furnished in writing to the Company by or on behalf of any Underwriter through you, expressly for use in connection therewith, or (b) any inaccuracy in or breach of the representations and warranties of the Company contained herein or any failure of the Company to perform its obligations hereunder or under law. This indemnification shall be in addition to any liability that the Company may otherwise have.

(b) Indemnification by Selling Stockholders. Subject to the limitations in this paragraph below, each Selling Stockholder, severally and not jointly, agrees to indemnify and hold harmless you and each other Underwriter, the directors, officers, employees and agents of each Underwriter, and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all Damages arising out of or based upon (a) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Commitment Prospectus, or the Prospectus or in any amendment or supplement thereto, or any Issuer Free Writing Prospectus, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in light of the circumstances under which they were made) not misleading, except to the extent that any such Damages arise out of or are based upon an untrue statement or omission or alleged untrue statement or omission that has

been made therein or omitted therefrom in reliance upon and in conformity with the information not expressly relating to the Selling Stockholders or the offering by them of their shares of Common Stock or furnished in writing to the Company by or on behalf of any Underwriter through you expressly for use in connection therewith, or (b) any inaccuracy in or breach of the representations and warranties of such Selling Stockholder contained herein or any failure of such Selling Stockholder to perform such Selling Stockholder's obligations hereunder or under law. This indemnification shall be in addition to any liability that the Selling Stockholders or any Selling Stockholder may otherwise have.

(c) Advancement of Expenses. In addition to its other obligations under this Section 8, each of the Company and the Selling Stockholders, severally and not jointly, agrees that, as an interim measure during the pendency of any claim, action, investigation, inquiry, or other proceeding arising out of or based upon any statement or omission, or any inaccuracy in the representations and warranties of the Company or the Selling Stockholders herein or failure to perform their respective obligations hereunder, all as set forth in this Section 8, the party against whom indemnification is being sought will reimburse each Underwriter on a monthly basis for all reasonable legal or other out-of-pocket expenses incurred in connection with investigating or defending any such claim, action, investigation, inquiry, or other proceeding (to the extent documented by reasonably itemized invoices therefor), notwithstanding the absence of a judicial determination as to the propriety and enforceability of the obligation of the Company or a Selling Stockholder to reimburse each Underwriter for such expenses and the possibility that such payments might later be held to have been improper by a court of competent jurisdiction. To the extent that any such interim reimbursement payment is so held to have been improper, each Underwriter shall promptly return it to the person(s) from whom it was received. Any such interim reimbursement payments that are not made to the Underwriters within 30 days of a request for reimbursement shall bear interest compounded daily at a rate determined on the basis of the base lending rate announced from time to time by The Wall Street Journal from the date of such request.

(d) Legal Counsel. If any action or claim shall be brought against any Underwriter or any person controlling any Underwriter in respect of which indemnity may be sought against the Company and any Selling Stockholder, such Underwriter or such controlling person shall promptly notify in writing the party(s) against whom indemnification is being sought (the "indemnifying party" or "indemnifying parties"), and such indemnifying party(s) shall assume the defense thereof, including the employment of counsel reasonably acceptable to such Underwriter or such controlling person and the payment of all reasonable fees of and expenses incurred by such counsel. Such Underwriter or any such controlling person shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Underwriter or such controlling person, unless (i) the indemnifying party(s) has (have) agreed in writing to pay such fees and expenses, (ii) the indemnifying party(s) has (have) failed to assume the defense and employ counsel reasonably acceptable to the Underwriter or such controlling person or (iii) the named parties to any such action (including any impleaded parties) include both such Underwriter or such controlling person and the indemnifying party(s), and such Underwriter or such controlling person shall have been advised by its counsel that one or more legal defenses may be available to the Underwriter that may not be available to the Company or the Selling Stockholders, or that representation of such indemnified party and any indemnifying party(s) by the same counsel would be inappropriate under applicable standards of professional conduct (whether or not such representation by the same counsel has been proposed) due to actual or potential differing interests between them (in which case the indemnifying party(s) shall not have the right to assume the defense of such action on behalf of such Underwriter or such controlling person (but the Company and the Selling Stockholders, as applicable, shall not be liable for the fees and expenses of more than one counsel

for the Underwriters and such controlling persons)). The indemnifying party(s) shall not be liable for any settlement of any such action effected without its (their several) written consent, but if settled with such written consent, or if there be a final judgment for the plaintiff in any such action, the indemnifying party(s) agree(s) to indemnify and hold harmless any Underwriter and any such controlling person from and against any loss, claim, damage, liability, or expense by reason of such settlement or judgment, but in the case of a judgment only to the extent stated in the first paragraph of this Section 8.

(e) Indemnification by Underwriters. Each Underwriter agrees, severally and jointly, to indemnify and hold harmless the Company and the Selling Stockholders, their respective directors, their respective officers who sign the Registration Statement, and any person who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, to the same extent as the foregoing several indemnity from the Company and the Selling Stockholders to each Underwriter, but only with respect to information furnished in writing by or on behalf of such Underwriter through you expressly for use in the Registration Statement, any Preliminary Prospectus, the Commitment Prospectus, the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus. If any action or claim shall be brought or asserted against the Company or the Selling Stockholders, any of their respective directors, any of their respective officers or any such controlling person based on the Registration Statement, any Preliminary Prospectus, the Commitment Prospectus, the Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus, and in respect of which indemnity may be sought against any Underwriter pursuant to this paragraph, such Underwriter shall have the rights and duties given to the Company and the Selling Stockholders by the immediately preceding paragraph (except that if the Company and the Selling Stockholders shall have assumed the defense thereof, such Underwriter shall not be required to do so, but may employ separate counsel therein and participate in the defense thereof, but the fees and expenses of such counsel shall be at such Underwriter's expense), and the Company and the Selling Stockholders, their respective directors, any such officers and any such controlling persons, shall have the rights and duties given to the Underwriters by the immediately preceding paragraph.

(f) Settlement of Claims. In any event, the Company and the Selling Stockholders will not, without the prior written consent of the Representative, settle or compromise or consent to the entry of any judgment in any proceeding or threatened claim, action, suit, or proceeding in respect of which the indemnification may be sought hereunder (whether or not the Representative or any person who controls such Representative within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act is a party to such claim, action, suit, or proceeding) unless such settlement, compromise, or consent includes an unconditional release of all Underwriters and such controlling persons from all liability arising out of such claim, action, suit, or proceeding.

(g) Contribution. If the indemnification provided for in this Section 8 is unavailable or insufficient for any reason whatsoever to an indemnified party in respect of any Damages referred to herein, then an indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Damages (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholders, respectively, on the one hand, and the Underwriters on the other hand, from the offering and sale of the Shares, 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 and several fault of the Company and the Selling Stockholders, respectively, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions that resulted in such Damages as well as any other relevant equitable considerations. The relative and several benefits received by the Company and the Selling Stockholders, respectively, on the one hand, and the Underwriters, on the other hand, 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; provided that, in the event that the Underwriters shall have purchased any Additional Shares hereunder, any determination of the relative benefits received by the Company and the Selling Stockholders or the Underwriters from the offering of the Shares shall include the net proceeds (before deducting expenses) received by the Company and the Selling Stockholders and the underwriting discounts and commissions received by the Underwriters, from the sale of such Additional Shares, in each case computed on the basis of the respective amounts set forth in the table on the cover page of the Prospectus. The relative fault of the Company and the Selling Stockholders, respectively, on the one hand, and the Underwriters, on the other hand, 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, on the one hand, or by the Underwriters, on the other hand, and the parties' relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission.

(h) Equitable Consideration. The Company, the Selling Stockholders, and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 was determined by a pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the Damages referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, 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, no Underwriter shall be required to contribute any amount in excess of the amount of the underwriting commissions received by such underwriter in connection with the Shares underwritten by it and distributed to the public. 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 pursuant to this Section 8 are several in proportion to the respective numbers of Firm Shares set forth opposite their names in Schedule I hereto (or such numbers of Firm Shares increased as set forth in Section 10 hereof) and not joint.

(i) Payments As Incurred. Notwithstanding the third paragraph of this Section 8, any Damages 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 Damages are incurred after receipt of reasonably itemized invoices therefor. The indemnity, contribution, and reimbursement agreements contained in this Section 8 and the several and not joint representations and warranties of the Company and the Selling Stockholders 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 or any person controlling any Underwriter, the Company, the Selling Stockholders, their respective directors or officers, or any person controlling the Company or the Selling Stockholders, (ii) acceptance of any Shares and payment therefor hereunder, and (iii) any termination of this Agreement. A successor to any Underwriter or any person controlling any Underwriter, or to the Company or the Selling Stockholders, their respective directors or officers, or any person controlling the Company or the Selling Stockholders, shall be entitled to the benefits of the indemnity, contribution, and reimbursement agreements contained in this Section 8.

(j) Arbitration. It is agreed that any controversy arising out of the operation of the interim reimbursement arrangements set forth in the second paragraph of this Section 8, including the amounts of any requested reimbursement payments and the method of determining such amounts,

shall be settled by arbitration conducted pursuant to the Code of Arbitration Procedure of the NASD. Any such arbitration must be commenced by service of a written demand for arbitration or written notice of intention to arbitrate, therein electing the arbitration tribunal. In the event the party demanding arbitration does not make such designation of an arbitration tribunal in such demand or notice, then the party responding to said demand or notice is authorized to do so. Such an arbitration would be limited to the operation of the interim reimbursement provisions contained in the third and fifth paragraphs of this Section 8, and would not resolve the ultimate propriety or enforceability of the obligation to reimburse expenses that is created by the provisions of the third paragraph of this Section 8.

9. Conditions of Underwriters' Obligations. The several obligations of the Underwriters to purchase the Firm Shares hereunder are subject to the following conditions:

(xx) The statements (i) in each of the Commitment Prospectus and the Prospectus under the captions"Risk Factors—We may not be able to maintain our domain name uniqueness"; "Risk Factors—Various legal rules and regulations related to privacy and the collection, dissemination and security of personal information may adversely affect our marketing efforts"; Risk Factors—We may be subject to liability for past sales and our future sales may decrease if we are required to collect sales and use tax on the products we sell"; "Risk Factors—Holders of common stock issued by us in prior offerings are entitled to rescind their purchases"; "Risk Factors—We may be subject to regulations governing the conduct and liability of auctioneers"; "Risk Factors—We are subject to regulations relating to consumer privacy"; "Risk Factors—New and existing regulations could harm our business"; "Business—Legal Proceedings"; "Business—Intellectual Property"; "Business—Governmental Regulation"; "Management"; "Certain relationships and related party transactions"; "Principal stockholders"; "Description of capital stock"; "Rescission offer"; "Shares eligible for future sale"; and "Underwriting" and (ii) in Item 14 and Item 15 of the Registration Statement, insofar as such statements constitute matters of law, summaries of legal matters, the Company's certificate of incorporation or bylaw provisions, documents, or legal proceedings, or legal conclusions, have been reviewed by such counsel and fairly present and summarize, in all material respects, the matters referred to therein.

In rendering such opinion, counsel may rely, to the extent they deem such reliance proper, as to matters of fact upon certificates of officers of the Company and of government officials, provided that counsel shall state their belief that they and you are justified in relying thereon. Copies of all such certificates shall be furnished to you and your counsel on the Closing Date and the Additional Closing Date, as the case may be.

In addition to the opinion set forth above, such counsel shall state that, during the course of such counsel's participation in the preparation of the Registration Statement, the Commitment Prospectus, the Prospectus, and the amendments and supplements thereto, and any Issuer Free Writing Prospectus, nothing has come to the attention of such counsel that has caused such counsel to believe or given such counsel reason to believe that any of the Registration Statement, the Commitment Prospectus, or the Prospectus or any amendment or supplement thereto (except for the financial statements and other financial and accounting information contained therein or omitted therefrom as to which no opinion need be expressed), and any Issuer Free Writing Prospectus, at the date thereof, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading or that any of the Registration Statement, the Commitment Prospectus, the Prospectus, and any Issuer Free Writing Prospectus, as of the date of the opinion (except as aforesaid), contains an untrue statement of a material fact or omits to state a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

(d) Opinion of Counsel to Selling Stockholders. You shall have received on the Closing Date (and the Additional Closing Date, if any) an opinion of [ ], counsel to the Selling Stockholders, substantially to the effect that:

(i) The Selling Stockholders have all requisite power and authority to enter into this Agreement and to sell and deliver the Shares to be sold by them to the Underwriters as provided herein. This Agreement has been duly authorized, executed, and delivered by, and is a valid and binding agreement of, the Selling Stockholders enforceable against the Selling Stockholders in accordance with its terms, except to the extent enforceability may be limited by (A) bankruptcy, reorganization, insolvency, or other laws affecting enforcement of creditors' rights generally and, (B) equitable principles being applied at the discretion of a court before which any proceeding may be brought, and except as to indemnity and contribution hereunder may be limited by federal or state securities laws.

(iii) Neither the offer, sale, or delivery of the Shares by the Selling Stockholders, the execution, delivery, or performance by the Selling Stockholders of this Agreement, the compliance by the Selling Stockholders with all provisions hereof nor consummation by the Selling Stockholders of the transactions contemplated hereby (A) conflicts or will conflict with or constitutes or will constitute a breach of, or a default under, the organizational documents of such Selling Stockholder, if such Selling Stockholder is not an individual, or any material agreement, indenture, lease, or other instrument to which such Selling Stockholder is a party or by which its properties are bound, (B) creates or will result in the creation or imposition of any lien, charge, or encumbrance upon any property or assets of such Selling Stockholder, or (C) violates or will result in any violation of any existing law, statute, regulation, ruling (assuming compliance with all applicable state and securities and Blue Sky laws), judgment, injunction, order, or decree that is known to such counsel and is applicable to such Selling Stockholder or any of its properties.

(iv) No consent, approval, authorization, or other order of, or registration or filing with, any court, regulatory body, administrative agency, or other governmental body, agency, or official is required on the part of the Selling Stockholders (except such as have been obtained under the Securities Act or such as may be required under state securities or Blue Sky laws governing the purchase and distribution of the Shares) for the valid sale of the Shares to the Underwriters by the Selling Stockholders under this Agreement.

(v) Each of the Custody Agreement and Power of Attorney of the Selling Stockholders has been duly authorized, executed, and delivered by the Selling Stockholders and is a valid, legal, and binding agreement of the Selling Stockholders enforceable against the Selling Stockholders in accordance with its terms, except to the extent enforceability may be limited by (A) bankruptcy, reorganization, insolvency, or other laws affecting enforcement of creditors' rights generally, and (B) equitable principles being applied at the discretion of a court before which any proceeding may be brought, and except as to indemnity and contribution may be limited by federal or state securities laws.

You shall have received on the Closing Date or Additional Closing Date, as the case may be, an opinion of ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇, LLP, as counsel for the Underwriters, dated the Closing Date or Additional Closing Date, as the case may be, with respect to such matters as you may reasonably request, and the Company and its counsel shall have furnished to your counsel such documents as they may reasonably request for the purpose of enabling your counsel to pass upon such matters.

(f) Comfort Letter. You shall have received letters addressed to you and dated the date hereof and the Closing Date or the Additional Closing Date, as the case may be, from the firm of Stonefield ▇▇▇▇▇▇▇▇▇, Inc., an independent registered public accounting firm, in form and substance satisfactory to you.

(g) Absence of Stop Orders or Misleading Information. (i) No stop order suspending the effectiveness of the Registration Statement shall have been issued by the Commission, and no proceedings for that purpose shall be pending or, to the best knowledge of the Company, shall be threatened or contemplated by the Commission at or prior to the Closing Date or Additional Closing Date, as the case may be; (ii) no order suspending the effectiveness of the Registration Statement or the qualification or registration of the Shares under the securities or Blue Sky laws of any jurisdiction shall be in effect, and no proceeding for such purpose shall be pending or, to the knowledge of the Company, threatened, initiated, or contemplated by the authorities of any jurisdiction; (iii) any request for additional information on the part of the staff of the Commission or any such authorities shall have been complied with to the satisfaction of the staff of the Commission or such authorities; (iv) after the date hereof, no amendment or supplement to any of the Registration Statement, the Commitment Prospectus, the Prospectus, or any Issuer Free Writing Prospectus shall have been filed unless a copy thereof was first submitted to you and you did not object thereto in good faith; and (v) all of the representations and warranties of the Company contained in this Agreement shall be true and correct in all material respects (except for such representations and warranties qualified by materiality, which representations and warranties shall be true and correct in all respects) on and as of the date hereof and on and as of the Closing Date or Additional Closing Date, as the case may be, as if made on and as of the Closing Date or Additional Closing Date, as the case may be, and you shall have received a certificate, dated the Closing Date and signed by the chief executive officer and the chief financial officer of the

(j) Receipt of Lock-Up Agreements. At or prior to the Closing Date, you shall have received Lock-Up Agreements from each of the Company's officers and directors, the Selling Stockholders, and others listed in Exhibit A not to directly or indirectly (i) sell, offer, or contract to sell or otherwise dispose of or transfer any shares of the Company's capital stock, whether now owned or acquired after the date of the Prospectus or with respect to which the power of disposition is acquired after the date of the Prospectus, or file any registration statement under the Securities Act with respect to the foregoing, or (ii) enter into any swap or other agreement or any other agreement that transfers, in whole or in part, directly or indirectly, the economic consequences of ownership of Company Securities whether any such swap or transaction is to be settled by delivery of Company Securities, in cash or otherwise; other than as provided in such written commitment before the expiration of 180 days from the Closing Date, without the prior written consent of ThinkEquity Partners, LLC

(k) Fairness of Underwriting Compensation. At or prior to the effective date of the Registration Statement, you shall have received a letter from the Corporate Financing Department of the NASD confirming that such Department has determined to raise no objections with respect to the fairness or reasonableness of the underwriting terms and arrangements of the offering contemplated hereby.

(l) Closing Certificates. You shall be satisfied that, and you shall have received a certificate dated the Closing Date or Additional Closing Date, as the case may be, from each Selling Stockholder to the effect that, as of the Closing Date or Additional Closing Date, as the case may be (i) the representations and warranties made by such Selling Stockholders herein are true and correct in all material respect on the Closing Date, and (ii) such Selling Stockholder has complied with all obligations and satisfied all conditions that are required to be performed or satisfied on his or its part at or prior to the Closing Date or Additional Closing Date, as the case may be.

All such opinions, certificates, letters, and other documents will be in compliance with the provisions hereof only if they are reasonably satisfactory in form and substance to you and your counsel.

The several obligations of the Underwriters to purchase Additional Shares hereunder are subject to the satisfaction on and as of the Additional Closing Date of the conditions set forth in this Section 9, except that, if the Additional Closing Date is other than the Closing Date, the certificates, opinions, and letters referred to in this Section 9 shall be dated as of the Additional Closing Date and the opinions called for by paragraphs (c), (d), and (e) shall be revised to reflect the sale of Additional Shares.

If any of the conditions hereinabove provided for in this Section 9 shall not have been satisfied when and as required by this Agreement, this Agreement may be terminated by you by notifying the Company of such termination in writing at or prior to such Closing Date, but you shall be entitled to waive any of such conditions.

10. Effective Date of Agreement. This Agreement shall become effective upon the later of (a) the execution and delivery hereof by the parties hereto, and (b) release of notification of the effectiveness of the Registration Statement by the Commission; provided, however, that the provisions of Sections 7 and 8 shall at all times be effective.

11. Defaulting Underwriters. If any one or more of the Underwriters shall fail or refuse to purchase Firm Shares that it or they have agreed to purchase hereunder, and the aggregate number of Firm Shares that such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Firm Shares, each non-defaulting Underwriter shall be obligated, severally, in the proportion in which the number of Firm Shares set forth opposite its name in Schedule I hereto bears to the aggregate number of Firm Shares set forth opposite the names of all non-defaulting Underwriters or in such other proportion as you may specify in the Agreement Among Underwriters, to purchase the Firm Shares that such defaulting Underwriter or Underwriters agreed, but failed or refused to purchase. If 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 and arrangements satisfactory to you and the Company for the purchase of such Firm Shares are not made within 48 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company. In any such case that does not result in termination of this Agreement, either you or the Company 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 and the Prospectus or any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any such default of any such Underwriter under this Agreement.

12. Termination of Agreement. This Agreement shall be subject to termination in your absolute discretion, without liability on the part of any Underwriter to the Company or the Selling Stockholders by notice to the Company and the Selling Stockholders, if prior to the Closing Date or the Additional Closing Date (if different from the Closing Date and then only as to the Additional Shares), as the case may be, in your sole judgment, (a) trading in the Company's Common Stock shall have been suspended by the Commission or the Nasdaq National Market; (b) trading in securities generally on the NYSE or Nasdaq shall have been suspended or materially limited, or minimum or maximum prices shall have been generally established on such exchange, or additional material governmental restrictions, not in force on the date of this Agreement, shall have been imposed upon trading in securities generally by any such exchange or by order of the Commission or any court or other governmental authority; (c) a general moratorium on commercial banking activities shall have been declared by either federal or New York State authorities; (d) there shall have occurred any outbreak or escalation of hostilities, terrorism, or other international or domestic calamity, crisis, or change in political, financial, or economic conditions or other material event the effect of which on the financial markets of the United States is such as to make it, in your judgment, impracticable or inadvisable to market the Shares or to enforce contracts for the sale of the Shares; or (e) the Company or any subsidiary shall have, in the sole judgment of the Representative, sustained any loss or interference, material to the Company and its subsidiaries, taken as a whole, with their respective businesses or properties from fire, flood, hurricane, accident, or other calamity, whether or not covered by insurance, or from any labor disputes or any legal or governmental proceeding, or there shall have been any material adverse change (including, without limitation, a material change in management or control of the Company) in the condition (financial or other), business prospects, net worth, or results of

operations of the Company and its subsidiaries, taken as a whole, except in each case as described in, or contemplated by, each of the Commitment Prospectus and the Prospectus (excluding any amendment or supplement thereto), the effect of which, in any such case described in clauses (a) through (e), is in your judgment, so material as to make it impractical or inadvisable to proceed with the public offering or purchase of the Shares as contemplated hereby. Notice of such cancellation shall be promptly given to the Company and its counsel by e-mail, facsimile, or telephone and shall be subsequently confirmed by letter.

13. Failure of One or More of the Selling Stockholders to Sell and Deliver the Shares. If one or more of the Selling Stockholders shall fail to sell and deliver to the Underwriters the Shares to be sold and delivered by such Selling Stockholders at the Closing Date pursuant to this Agreement, then the Underwriters may at their option, by written notice from the Representatives to the Company and the Selling Stockholders, either (i) terminate this Agreement without any liability on the part of any Underwriter or, except as provided in Sections 7 and 8 hereof, the Company or the Selling Stockholders, in the event the Underwriters or their counsel deem such failure to sell and deliver Shares to be material, or (ii) purchase the Shares that the Company and other Selling Stockholders have agreed to sell and deliver in accordance with the terms hereof. Notwithstanding the foregoing, if one or more of the Selling Stockholders shall fail to sell and deliver to the Underwriters the Shares to be sold and delivered by such Selling Stockholders pursuant to this Agreement at the Closing Date or Additional Closing Date, then the Underwriters shall have the right, by written notice from the Representative to the Company and the Selling Stockholders, to postpone the Closing Date or the Additional Closing Date, as the case may be, but in no event for longer than seven days in order that the required changes, if any, to the Registration Statement and the Prospectus or any other documents or arrangements may be effected.

14. Information Furnished by the Underwriters. The Company acknowledges that the fourth, twelfth, thirteenth, fourteenth, fifteenth, seventeenth, and twentieth paragraphs under the caption "Underwriting" in each of the Commitment Prospectus and the Prospectus, constitute the only information furnished by or on behalf of the Underwriters through you or on your behalf as such information is referred to in Sections 6.1(a), 6.1(b), and 8 hereof.

15. Notices. Except as otherwise provided in Sections 5 and 12 hereof, all notices given pursuant to any of the provisions of this Agreement shall be in writing and shall be effective only upon receipt and shall be delivered personally or sent by mail, overnight courier service, e-mail, or facsimile addressed as follows:

16. Entire Agreement. This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Shares, represents the entire agreement between the parties with respect to the preparation of any Preliminary Prospectus, the Commitment Prospectus, the Prospectus, the conduct of this offering, and the purchase and sale of the Shares. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Selling Stockholders, on the one hand, and the Underwriters, on the other, with respect to the subject matter hereof.

17. Authority. In all dealings hereunder, you shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice, or agreement on behalf of any Underwriter made or given by you jointly or by ThinkEquity Partners, LLC on behalf of you as the Representative, and in all dealings with any Selling Stockholder hereunder, you and the Company shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of such Selling Stockholder made or given by any or all of the Attorneys-in-Fact for such Selling Stockholder.

18. Nature of Transaction. Each of the Company and each Selling Stockholder acknowledges and agrees that (a) the purchase and sale of the Shares pursuant to this Agreement is an arm's-length commercial transaction between the Company and the Selling Stockholders, on the one hand, and the several Underwriters, on the other hand, (b) in connection therewith and with the process leading to such transaction, each Underwriter is acting solely as a principal and not the agent or fiduciary of the Company or any Selling Stockholder with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company or any Selling Stockholder on other matters) or any other obligation to the Company or any Selling Stockholder, except the obligations expressly set forth in this Agreement, and (c) the Company and each Selling Stockholder have consulted its own legal and financial advisors to the extent it deemed appropriate. Each of the Company and each Selling Stockholder agrees that it will not claim that the Underwriters, or any of them, have rendered advisory services of any nature or respect, or owe

a fiduciary or similar duty to the Company or such Selling Stockholder in connection with such transaction or the process leading thereto.

19. Waiver of Jury Trial. The Company, each Selling Stockholder, and each of the Underwriters hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

20. Binding Effect. This Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, and the Company, and the Selling Stockholders and, to the extent expressly provided herein, the officers and directors of the Company and each person who controls the Company, any Selling Stockholder, or any Underwriter, and their respective heirs, executors, administrators, successors, and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Shares from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

21. Time of Essence. Time shall be of the essence of this Agreement. As used herein, the term "business day" shall mean any day when the Commission's office in Washington, D.C. is open for business.

22. Applicable Law. This Agreement shall be governed by and construed in accordance with the laws of the state of New York without reference to choice of law principles thereunder.

23. Counterparts. This Agreement may be signed in various counterparts, which together shall constitute one and the same instrument. This Agreement shall be effective when, but only when, at least one counterpart hereof shall have been executed on behalf of each party hereto.

24. Headings. The headings of the Sections of this Agreement have been inserted for convenience of reference only and shall not be deemed part of this Agreement.

25. Information Incorporated By Reference. To the extent that information is incorporated by reference into any Preliminary Prospectus, the Commitment Prospectus, the Prospectus, or the Registration Statement pursuant to the rules and regulations of the Commission, the terms "Preliminary Prospectus," "Commitment Prospectus," "Prospectus," and "Registration Statement," as the case may be, shall be deemed to include the information so incorporated.
