The terms and conditions of the Warrants are set forth in the form of Exhibit B attached hereto. The Company hereby confirms its agreement with Credit Suisse Securities (USA) LLC (“Credit Suisse”) to act as lead placement agent and with Canaccord Xxxxx Inc. (“Canaccord”) and Cantor Xxxxxxxxxx & Co. (“Cantor”) to act as co-placement agents (Credit Suisse, Canaccord and Cantor, the “Placement Agents”) in accordance with the terms and conditions hereof as set forth below.

Until the Closing Date (defined below), the Company shall not, without the prior consent of Credit Suisse, solicit or accept offers to purchase Units otherwise than through the Placement Agents.

(b) Under no circumstances will the Placement Agents be obligated to purchase any Units for their own account and, in soliciting purchases of Units, the Placement Agents shall act solely as the Company’s agents and not as principals. Notwithstanding the foregoing and except as otherwise provided in Section 2(c), it is understood and agreed that the Placement Agents (or their affiliates) may, solely at their discretion and without any obligation to do so, purchase Units as principals to the extent any such purchase of Units is properly disclosed in the General Disclosure Package in the manner required by the Securities Laws.

(c) Subject to the provisions of this Section 2, offers for the purchase of Units may be solicited by the Placement Agents as agents for the Company at such times and in such amounts as the Placement Agents deem advisable. The Placement Agents shall communicate to the Company, orally or in writing, each reasonable offer to purchase Units received by it as agents of the Company. The Company shall have the sole right to accept offers to purchase the Units and may reject any such offer, in whole or in part. The Placement Agents shall have the right, in their discretion reasonably exercised, without notice to the Company, to reject any offer to purchase Units received by it, in whole or in part, and any such rejection shall not be deemed a breach of their agreement contained herein.

(d) The purchases of the Units by the Purchaser shall be evidenced by the execution of the Subscription Agreement by each of the parties thereto.

(e) As compensation for services rendered, on the Closing Date, the Company shall pay to the Placement Agents by wire transfer of immediately available funds to an account or accounts designated by the Placement Agents, an aggregate amount equal to five percent (5%) of the gross proceeds received by the Company from the sale of the Units on such Closing Date (such aggregate amount to be divided among the Placement Agents as they so agree).

(f) No Units which the Company has agreed to sell pursuant to this Agreement shall be deemed to have been purchased and paid for, or sold by the Company, until such Units shall have been delivered to the Purchaser thereof against payment by such Purchaser.

of the purchase and sale of the Units contemplated herein and will afford the Placement Agents a reasonable opportunity to comment on any such proposed amendment or supplement; and the Company will also advise the Placement Agents promptly of (i) the filing of any such amendment or supplement, (ii) any request by the Commission or its staff for any amendment to the Registration Statement, for any supplement to any Statutory Prospectus or for any additional information, (iii) the institution by the Commission of any stop order proceedings in respect of the Registration Statement or the threatening of any proceeding for that purpose, and (iv) the receipt by the Company of any notification with respect to the suspension of the qualification of the Units (including the Shares and Warrant Shares) in any jurisdiction or the institution or threatening of any proceedings for such purpose. The Company will use its best efforts to prevent the issuance of any such stop order or the suspension of any such qualification and, if issued, to obtain as soon as possible the withdrawal thereof.

(c) Continued Compliance with Securities Laws. If, at any time when a prospectus relating to the Units is (or but for the exemption in Rule 172 under the Act would be) required to be delivered under the Act in connection with sales by the Company to any Purchaser, any event occurs as a result of which the Final Prospectus as then amended or supplemented would include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend the Registration Statement or supplement the Final Prospectus to comply with the Act, the Company will promptly notify the Placement Agents of such event and will promptly prepare and file with the Commission and furnish, at its own expense, to the Placement Agents and, to the extent applicable, the dealers and any other dealers upon request of the Placement Agents, an amendment or supplement which will correct such statement or omission or an amendment which will effect such compliance. Neither the Placement Agents’ consent to, nor the Placement Agents’ delivery of, any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 7 hereof.

(d) Rule 158. As soon as practicable, but not later than 16 months, after the date of this Agreement, the Company will make generally available to its securityholders an earnings statement covering a period of at least 12 months beginning after the date of this Agreement and satisfying the provisions of Section 11(a) of the Act and Rule 158.

(e) Furnishing of Prospectuses. The Company will furnish to the Placement Agents copies of the Registration Statement, including all exhibits, any Statutory Prospectus relating to the Units, the Final Prospectus and all amendments and supplements to such documents, in each case as soon as available and in such quantities as the Placement Agents reasonably requests. The Company will pay the expenses of printing and distributing to the Placement Agents all such documents.

(f) Blue Sky Qualifications. The Company will arrange for the qualification of the Units for sale under the laws of such jurisdictions as the Placement Agents designate and will continue such qualifications in effect so long as required for the distribution; provided that the Company will not be required to qualify as a foreign corporation or to file a general consent to service of process in any such jurisdiction or take any action that would subject it to taxation in any such jurisdiction where it is not then so subject.

(g) Reporting Requirements. During the period of five years after the date of the this Agreement, the Company will furnish to the Placement Agents as soon as practicable after the end of each fiscal year, a copy of its annual report to stockholders for such year; and the Company will furnish to the Placement Agents (i) as soon as available, a copy of each report and any definitive proxy statement of the Company filed with the Commission under the Exchange Act or mailed to stockholders, and (ii) from time to time, such other information concerning the Company as the Placement Agents may reasonably request. However, so long as the Company is subject to the reporting requirements of either Section 13 or Section 15(d) of the Exchange Act and is timely filing reports with the Commission on its Electronic Data Gathering, Analysis and Retrieval system (“XXXXX”), it is not required to furnish such reports or statements to the Placement Agents.

(h) Payment of Expenses. The Company will pay all fees and expenses incident to the performance of the its obligations under this Agreement, including but not limited to (i) any filing fees and other expenses (including reasonable fees and disbursements of counsel to the Placement Agents) incurred in connection with qualification of the Units for sale under the laws of such jurisdictions as the Placement Agents may designate and the preparation and printing of memoranda relating thereto, (ii) any costs and expenses related to, the review by FINRA of the Units (including filing fees and the reasonable fees and dispursements of counsel for the Placement Agents relating to such review), (iii) any travel expenses of the Company’s officers and employees and any other expenses of the Company in connection with attending or hosting meetings with prospective purchasers of the Units, (iv) fees and expenses incident to listing the Shares and Warrant Shares on the NASDAQ Global Market and other national and foreign exchanges, (v) fees and expenses in connection with the registration of the Units under the Exchange Act, (vi) fees and expenses incurred in distributing any Statutory Prospectuses and the Final Prospectus (including any amendments and supplements thereto) to the Placement Agents and for expenses incurred for preparing, printing and distributing any Issuer Free Writing Prospectuses to investors or prospective investors, (vii) fees and expenses of any escrow agent and under any escrow agreement, and (viii) all other costs and expenses incurred by the Company incident to the performance of the obligations of the Company hereunder for which provision is not otherwise made in this Section.

(i) Use of Proceeds. The Company will use the net proceeds received in connection with any offering of the Units in the manner described in the “Use of Proceeds” section of the General Disclosure Package and, except as disclosed in the General Disclosure Package, the Company does not intend to use any of the proceeds from the sale of the Units hereunder to repay any outstanding debt owed to any affiliate of the Placement Agents.

(j) Absence of Manipulation. The Company will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, stabilization or manipulation of the price of any securities of the Company to facilitate the sale or resale of the Units.

(k) Restriction on Sale of Securities. For the period specified below (the “Lock-Up Period”), the Company will not, directly or indirectly, take any of the following actions with respect to its Common Stock or any securities convertible into or exchangeable or exercisable for its Common Stock (“Lock-Up Securities”): (i) offer, sell, issue, contract to sell, pledge or otherwise dispose of, Lock-Up Securities, (ii) offer, sell, issue, contract to sell, contract to purchase or grant any option, right or warrant to purchase Lock-Up Securities, (iii) enter into any swap, hedge or any other agreement that transfers, in whole or in part, the economic consequences of ownership of Lock-Up Securities, (iv) establish or increase a put equivalent position or liquidate or decrease a call equivalent position in Lock-Up Securities within the meaning of Section 16 of the Exchange Act or (v) file with the Commission a registration statement under the Act relating to Lock-Up Securities, or publicly disclose the intention to take any such action, without the prior written consent of Credit Suisse, except issuances of Lock-Up Securities pursuant to the conversion of convertible securities or the exercise of warrants or options, in each case outstanding on the date of this Agreement, grants of employee stock options pursuant to the terms of a plan in effect on the date of this Agreement, or issuances of Lock-Up Securities pursuant to the exercise of such options. The initial Lock-Up Period will commence on the date hereof and continue for 90 days after the date of the commencement of the public offering of the Units or such earlier date that Credit Suisse consents to in writing; provided, however, that if (1) during the last 17 days of the initial Lock-Up Period, the Company releases earnings results or material news or a material event relating to the Company occurs or (2) prior to the expiration of the initial Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the initial Lock-Up Period, then in each case the Lock-Up Period will be extended until the expiration of the 18-day period beginning on the date of release of the earnings results or the occurrence of the materials news or material event, as applicable, unless Credit Suisse waives, in writing, such extension. The Company will provide the Placement Agents with notice of any announcement described in clause (2) of the preceding sentence that gives rise to an extension of the Lock-Up Period.

6. Free Writing Prospectuses. The Company represents and agrees that, unless it obtains the prior consent of the Placement Agents, and each Placement Agent, severally and not jointly, represents and agrees that, unless it obtains the prior consent of the Company, it has not made and will not make any offer relating to the Units that would constitute an Issuer Free Writing

Prospectus, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Company and the Placement Agents, each of which is set forth on Schedule A hereto, is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company represents that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including timely Commission filing where required, legending and record keeping.

7. Conditions of the Obligations of the Placement Agents. The obligations of the Placement Agents hereunder will be subject to the accuracy of the representations and warranties of the Company herein (as though made on the Closing Date), to the accuracy of the statements of Company officers made pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions precedent:

8. Indemnification and Contribution.

(a) Indemnification of Placement Agents. The Company will indemnify and hold harmless each Placement Agent, its partners, members, directors, officers, employees, agents, affiliates and each person, if any, who controls any Placement Agent within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each, an “Indemnified Party”), against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject, under the Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of the Registration Statement at any time, any Statutory Prospectus as of any time, the Final Prospectus or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending against any such loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Indemnified Party is a party thereto), whether threatened or commenced, and in connection with the enforcement of this provision with respect to any of the above as such expenses are incurred; 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 in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Company by the Placement Agents specifically for use therein, it being understood and agreed that the only such information furnished by the Placement Agents consists of the information described as such in subsection (b) below.

(b) Indemnification of Company. Each Placement Agent will, severally and not jointly, indemnify and hold harmless the Company, each of its directors and each of its officers who signs the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (each, a “Placement Agent Indemnified Party”), against any losses, claims, damages or liabilities to which such Placement Agent Indemnified Party may become subject, under the Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of the Registration Statement at any time, any Statutory Prospectus as of any time, the Final Prospectus or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or the alleged omission of 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 reliance upon and in conformity with written information furnished to the

Company by such Placement Agent specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by such Placement Agent Indemnified Party in connection with investigating or defending against any such loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Placement Agent Indemnified Party is a party thereto), whether threatened or commenced, based upon any such untrue statement or omission, or any such alleged untrue statement or omission as such expenses are incurred, it being understood and agreed that no such information has been furnished by any Placement Agent.

(c) Actions against Parties; Notification. Promptly after receipt by an indemnified party under this Section 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 of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(d) Contribution. If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party 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, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Placement Agents on the other from the offering of the Units or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect

not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and the Placement Agents on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Placement Agents 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 bear to the total underwriting discounts and commissions received by the Placement Agents. 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 Placement Agents and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), the Placement Agents shall not be required to contribute any amount in excess of the amount by which total compensation received by the Placement Agents in accordance with Section 2(e) exceeds the amount of any damages which the Placement Agents have otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Company and the Placement Agents agree that it would not be just and equitable if contribution pursuant to this Section 8(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 8(d).

(e) Control Persons. The obligations of the Company under this Section shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Placement Agent within the meaning of the Act; and the obligations of the Placement Agents under this Section shall be in addition to any liability which the Placement Agents 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 and to each person, if any, who controls the Company within the meaning of the Act.

9. Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Company or its officers and of the Placement Agents set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of the Placement Agents, the Company or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Units. If the sale and issuance of

the Units by the Company hereunder are not consummated for any reason, the Company will reimburse the Placement Agents for all out of pocket expenses (including fess and disbursements of counsel) reasonably incurred in connection with the offering of the Units, and the respective obligations of the Company and the Placement Agents pursuant to Section 8 hereof shall remain in effect. In addition, if any Units have been purchased under this Agreement and the Subscription Agreement, the representations and warranties in Section 4 hereof and all obligations under Section 5 hereof shall also remain in effect.

10. Notices. All communications hereunder will be in writing and, if sent to the Placement Agents, will be mailed, delivered or telegraphed and confirmed to (a) Credit Suisse Securities (USA) LLC, Eleven Xxxxxxx Xxxxxx, Xxx Xxxx, XX 00000-0000, Attention: LCD-IBD, (b) Canaccord Xxxxx Inc., 00 Xxxx Xxxxxx, Xxxxxx, XX 00000, and (c) Cantor Xxxxxxxxxx & Co., 000 Xxxx 00^xx Xxxxxx, Xxx Xxxx, XX 00000, or, if sent to the Company, will be mailed, delivered or telegraphed and confirmed to it at 000 Xxxxxx Xxxxxxxxx, Xxxxx Xxx Xxxxxxxxx, XX 00000, Attention: Chief Financial Officer.

11. Successors. This Agreement will inure to the benefit of and be binding upon parties hereto and their respective successors and the officers and directors and controlling persons referred to in Section 8, and no other person will have any right or obligation hereunder.

12. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement.

13. Absence of Fiduciary Relationship. The Company acknowledges and agrees that:

(a) No Other Relationship. The Placement Agents have been retained solely to act as placement agents in connection with the sale of Units and that no fiduciary, advisory or agency relationship between the Company and the Placement Agents has been created in respect of any of the transactions contemplated by this Agreement, any Subscription Agreement or the Final Prospectus, irrespective of whether the Placement Agents have advised or is advising the Company on other matters;

(b) Arm’s-Length Negotiations. The price of the Units set forth in this Agreement was established by the Company following discussions and arm’s-length negotiations with the Placement Agents and the Company is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement;

(c) Absence of Obligation to Disclose. The Company has been advised that the Placement Agents and their affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Company and that the Placement Agents have no obligation to disclose such interests and transactions to the Company by virtue of any fiduciary, advisory or agency relationship; and

(d) Waiver. The Company waives, to the fullest extent permitted by law, any claims it may have against the Placement Agents for breach of fiduciary duty or alleged breach of fiduciary duty and agrees that the Placement Agents shall have no liability (whether direct or indirect) to the Company in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company, including stockholders, employees or creditors of the Company.

14. Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

The Company hereby submits to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated thereby. The Company irrevocably and unconditionally waives any objection to the laying of venue of any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated thereby in Federal and state courts in the Borough of Manhattan in The City of New York and irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such suit or proceeding in any such court has been brought in an inconvenient forum.
