Notwithstanding the foregoing, it is understood and agreed that the Placement Agent or any of its respective affiliates may, solely at its discretion and without any obligation to do so, purchase Securities as principal;provided, however, that any such purchases by the Placement Agent (or its respective affiliates) shall be fully disclosed to the Company and approved by the Company in accordance with the previous sentence. The Placement Agent acknowledges and agrees that the Company may continue to issue and sell the Company’s Common Stock through an at-the-market offering of the Company’s Common Stock under the Company’s distribution agreement with Wedbush Securities, Inc., as amended (the “ATM Offering”) and that (a) the ATM Offering will not be considered a breach of any

of the terms or conditions of this Agreement and (b) no compensation will be payable to the Placement Agent under this Agreement with respect to sales made through the ATM Offering.

(b) This Agreement shall not give rise to any commitment by the Placement Agent to purchase any of the Securities, and the Placement Agent shall have no authority to bind the Company. The Placement Agent shall act on a reasonable efforts basis and does not guarantee that it will be able to raise new capital in the Offering. Prior to the earlier of (i) the date on which this Agreement is terminated and (ii) the Closing Date (as defined below), the Company shall not, without the prior written consent of the Placement Agent, solicit or accept offers to purchase Securities of the Company (other than pursuant to the grant of options or restricted stock awards under the Company’s equity compensation plans or the exercise of options or warrants to purchase shares of Common Stock that are outstanding at the date hereof) otherwise than through the Placement Agent in accordance herewith.

(c) The Company acknowledges and agrees that the Placement Agent shall act as an independent contractor, and not as a fiduciary, and any duties of the Placement Agent with respect to investment banking services to the Company, including the offering of the Securities contemplated hereby (including in connection with determining the terms of the Offering), shall be contractual in nature, as expressly set forth herein, and shall be owed solely to the Company.

Neither the Company nor any of the Subsidiaries has any reason to believe that it will not be able to renew its existing insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business at a cost that would not have a Material Adverse Effect.

There are no significant deficiencies and material weaknesses in the design or operation of internal controls which could adversely affect the Company’s ability to record, process, summarize, and report financial data to management and the Board of Directors. The Company is not aware of any fraud, whether or not material, that involves management or other employees who have a role in the Company’s internal controls; and since the date of the most recent evaluation of such disclosure controls and procedures, there have been no significant changes in internal controls or in other factors that could significantly affect internal controls, including any corrective actions with regard to significant deficiencies and material weaknesses.

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, result in a Material Adverse Effect.

Section 6. Indemnification and Contribution.

(a) Indemnification of the Placement Agent. The Company agrees to indemnify, defend and hold harmless each of the Placement Agent, its respective directors and officers, and each person, if any, who controls the Placement Agent within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons (collectively, “Placement Agent Indemnitees”), from and against any loss, damage, claim or liability, which, jointly or severally, the Placement Agent or any such person may become subject under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, the common law or otherwise, (including in settlement of any litigation, if such settlement is effected with the written consent of the Company), insofar as such loss, damage, claim or liability (or actions in respect thereof as contemplated below) arises out of or is based upon: (i) any 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 a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made therein, in light of the circumstances under which they were made, not misleading; and, in the case of (i) and (ii) above, to reimburse the Placement Agent and each such controlling person for any and all reasonable expenses (including reasonable, documented out-of-pocket fees and disbursements of counsel) as such expenses are incurred by the Placement Agent or such controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action;provided,however, that the foregoing indemnity shall not apply to any loss, claim, damage, liability or expense to the extent, but only to the extent, it arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in or omitted from, and in conformity with information concerning the Placement Agent furnished in writing by or on behalf of the Placement Agent to the Company expressly for use therein, which information the parties hereto agree is limited to the Placement Agent Information (as defined inSection 7), (iii) any breach of a representation made inSection 2 hereof or the failure by the Company to perform when and as required any agreement or covenant contained herein or (iv) any untrue statement or alleged untrue statement of any material fact contained in any audio or visual materials provided to Investors by or with the approval of the Company and based upon and in conformity with written information furnished by or on behalf of the Company for distribution to Investors including, without limitation, slides, videos, films or tape recordings used in any road show or investor presentations made to investors by the Company (whether in person or electronically) or in connection with the marketing of the Securities. Notwithstanding the foregoing, the Company will not be liable to any Placement Agent Indemnitee pursuant to thisSection 6(a) to the extent that any such loss, damage, claim or liability is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from any Placement Agent Indemnitee’s willful misconduct or gross negligence.

(b) Indemnification of the Company. The Placement Agent will indemnify, defend and hold harmless the Company, its directors and officers, and any person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, claim, damage, liability or expense, as incurred to which, jointly or severally, the Company or any such person may become

subject under the Securities Act, the Exchange Act, or other federal or state statutory law or regulation, the common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Placement Agent), insofar as such loss, claim, damage, liability or expense (or actions in respect thereof as contemplated below) arises out of or is based upon (i) any 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 therefrom to state a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements made therein, in light of the circumstances under which they were made, not misleading, in the case of each of (i) and (ii) above, 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, Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with information concerning such Placement Agent furnished in writing by or on behalf of such Placement Agent to the Company expressly for use therein and to reimburse the Company, or any such director, officer or controlling person for any legal and other expense reasonably incurred by the Company, or any such director, officer or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, that the parties hereto hereby agree that such written information provided by the Placement Agent consists solely of the Placement Agent Information.

(c) Notice and Procedures. If any action, suit or proceeding (each, a “Proceeding”) is brought against a person (an “indemnified party”) in respect of which indemnity may be sought against the Company or any Placement Agent (as applicable, the “indemnifying party”) pursuant tosubsection (a) or(b), respectively, of thisSection 6, such indemnified party shall promptly notify such indemnifying party in writing of the institution of such Proceeding and such indemnifying party shall assume the defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses;provided, however, that the omission to so notify such indemnifying party shall not relieve such indemnifying party from any liability which such indemnifying party may have to any indemnified party or otherwise, except to the extent such failure materially prejudices the indemnifying party. The indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (i) the employment of such counsel shall have been authorized in writing by the indemnifying party in connection with the defense of such Proceeding, (ii) the indemnifying party shall not have, within a reasonable period of time in light of the circumstances, employed counsel to defend such Proceeding or (iii) such indemnified party or parties shall have reasonably concluded that a conflict or reasonably likely conflict exists (based upon the advice of counsel of such indemnified party) between such indemnified party and the indemnifying party that makes it impossible or inadvisable for counsel to the indemnifying party to conduct the defense of both the indemnfied party and the indemnifying party, in any of which events such reasonable fees and expenses shall be borne by such indemnifying party and paid as incurred (it being understood, however, that such indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding). An indemnifying party shall not be liable for any settlement of any Proceeding (including by consent to the entry of any judgment) effected without its written consent but, if settled with its written consent or if there be a final judgment for the plaintiff, such indemnifying party agrees to indemnify and hold harmless the indemnified party or parties from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to

reimburse the indemnified party for fees and expenses of counsel (which fees and expenses shall be reasonably documented) as contemplated by the second sentence of thisSection 6(c), then the indemnifying party agrees that it shall be liable for any settlement of any Proceeding effected without its written consent if (i) such settlement is entered into more than 90 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have fully reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 30 days’ prior notice of its intention to settle. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened Proceeding 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 includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding and does not include an admission of fault or culpability or a failure to act by or on behalf of such indemnified party.

(d) In the event that an indemnified party is required or required to appear as a witness in any action brought by or on behalf of or against the indemnifying party in which such indemnified party is not named as a defendant, the indemnifying party agrees to promptly reimburse the indemnified party on a monthly basis for all documented, out-of-pocket expenses incurred by it in connection with such indemnified party’s appearing and preparing to appear as such a witness, including, without limitation, the reasonable fees and disbursements of its legal counsel.

(e) Contribution. If the indemnification provided for in thisSection 6 is unavailable to an indemnified party undersubsections (a) or(b) of this Section 6 or insufficient to hold an indemnified party harmless in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each applicable indemnifying party shall, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages, liabilities or expenses referred to insubsection (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 Agent on the other from the offering of the Securities 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 indemnifying party or parties on the one hand and the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Placement Agent on the other hand shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities (before deducting expenses) received by the Company and the Placement Fee received by the Placement Agent, in each case as set forth on the cover of the Prospectus, bear to the aggregate public offering price of the Securities. The relative fault of the Company on the one hand and the Placement Agent 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 Placement Agent, on the other hand, and the parties’ relevant intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Placement Agent agree that it would not be just and equitable if contribution pursuant to thissubsection (d) were to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the first sentence of thisSection 6(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of thisSection 6(d) 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 thisSection 6(d). Notwithstanding the provisions of thisSection 6(d), the Placement Agent shall not be required to contribute any amount in excess of the Placement Fee. 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.

(f) Representations and Agreements to Survive Delivery. The obligations of the Company under thisSection 6 shall be in addition to any liability which the Company may otherwise have. The indemnity and contribution agreements of the parties contained in thisSection 6 and the covenants, warranties and representations of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Placement Agent, any person who controls any Placement Agent within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or any affiliate of any Placement Agent, or by or on behalf of the Company, its directors or officers or any person who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and (iii) the issuance and delivery of the Securities. The Company and each of the Placement Agent agree promptly to notify each other of the commencement of any Proceeding against it and, in the case of the Company, against any of the Company’s officers or directors in connection with the issuance and sale of the Securities, or in connection with the Registration Statement, the Disclosure Package or the Prospectus.

Section 7. Information Furnished by Placement Agent.

The Company acknowledges that the statements set forth under the heading “Plan of Distribution” in the Prospectus (the “Placement Agent Information”) constitute the only information relating to the Placement Agent furnished in writing to the Company by the Placement Agent as such information is referred to inSections 2 and6 hereof.

Section 8. Termination.

(a) The Placement Agent shall have the right to terminate this Agreement by giving notice as hereinafter specified at any time at or prior to the Closing Date, without liability on the part of the Placement Agent to the Company, if (i) prior to delivery and payment for the Securities (A) trading in securities generally shall have been suspended or materially limited on or by the New York Stock Exchange, the NASDAQ Stock Market, the NASDAQ Global Select Market, the NASDAQ Global Market, the NASDAQ Capital Market or the NYSE Amex (each, a “Trading Market”), (B) trading in the shares of Common Stock of the Company shall have been suspended or materially limited on any exchange or in the over-the-counter market, or (C) a general moratorium on commercial banking activities shall have been declared by federal or New York state authorities, or (ii) since the time of execution of this Agreement or the earlier respective dates as of which information is given in the Disclosure Package, there has been (A) any Material Adverse Effect or (B) the Company shall have sustained a loss by strike, fire, flood, earthquake, accident or other calamity of such character that in the reasonable judgment of the Placement Agent would, individually or in the aggregate, result in a Material Adverse Effect and which would, in the judgment of the Placement Agent, make it impracticable or inadvisable to proceed with the offering or the delivery of the Securities on the terms and in the manner contemplated in the Disclosure Package. Any such termination shall be without liability of any party to any other party except that the provisions ofSection 4,Section 6,Section 8(b) andSection 11 hereof shall at all times be effective notwithstanding such termination.

(b) If (1) this Agreement shall be terminated by the Placement Agent pursuant toSection 5,Section 8(a)(i)(B) orSection 8(a)(ii)(A) or (2) the sale of the Securities to Investors is not consummated because of any failure, refusal or inability on the part of the Company to comply with the terms or perform any agreement or obligation of this Agreement or any Subscription Agreement, other than by reason of a default by the Placement Agent or an Investor, the Company will, in addition to paying the amounts described inSection 4 hereof other than Placement Agent Expenses, reimburse the Placement Agent for all of its reasonable, documented out-of-pocket disbursements (including, but not limited to, the reasonable fees and disbursements of its counsel) that would have been payable at Closing underSection 4 if the gross proceeds received by the Company at Closing had been $3,000,000.
