The Placement Agent Warrants, in the form attached hereto as Exhibit B, shall be immediately exercisable on the date of issuance, in whole or in part, and expiring on the five year anniversary of the date of issuance, at an initial exercise price of $2.66 per Common Share, which is equal to 125% of the purchase price of the Shares under the Securities Purchase Agreement.

(d) No Material Adverse Effect. Subsequent to the execution and delivery of this Agreement and as of the Closing Date, there shall not have occurred any change, event or development resulting or that could reasonably be expected to result in a Material Adverse Effect, which, in the Placement Agent's sole judgment, makes it impracticable or inadvisable to proceed with the Offering.

If any condition specified in this Section 7 is not satisfied when and as required to be satisfied, this Agreement may be terminated by the Placement Agent by notice to the Company at any time on or prior to the Closing Date, which termination shall be without liability on the part of any party to any other party, except that Section 1(b), Section 2, Section 8 and Section 9 shall at all times be effective and shall survive such termination.

Section 8. Indemnification and Contribution.

(a) Indemnification of the Placement Agent. In consideration of the Placement Agent's execution and delivery of, and the performance of its obligations under, this Agreement, and in addition to all of the Company's other obligations under the Offering Documents, the Company shall defend, indemnify and hold harmless the Placement Agent, each of its Affiliates, each Person, if any, who controls the Placement Agent or any of its Affiliates within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and each of its and its directors, officers, partners, members, shareholders, direct or indirect investors, employees, representatives and agents (including, without limitation, those attorneys and other agents retained by Placement Agent or any such other Person in connection with the transactions contemplated by this Agreement and the other Offering Documents) (collectively, the "Placement Agent Indemnified Parties," and each a "Placement Agent Indemnified Party"), from and against any and all claims, actions, causes of action, suits, proceedings (including, without limitation, as a party in interest or otherwise in any action or proceeding for injunctive or other equitable relief), including, without limitation, any and all derivative actions brought on behalf of the Company or any majority or wholly owned subsidiary (each, a "Subsidiary"), and any and all civil, criminal or regulatory investigations, whether formal or informal, to which any Placement Agent Indemnified Party may become subject (irrespective of whether any such Placement Agent Indemnified Party is a party, threatened to be made a party, or a witness to the claim, action, cause of action, suit, proceeding or investigation for which indemnification hereunder is sought), and all damages, losses, liabilities and expenses (including the reasonable fees and expenses of counsel) incurred by any Placement Agent Indemnified Party (including, without limitation, in settlement of any claim, action, cause of action, suit, proceeding or investigation), in each case as incurred (collectively, a "Claim"), as a result of, or arising out of, or relating to (i) any misrepresentation, inaccuracy or breach of any representation or warranty made by the Company or any Subsidiary in this Agreement or in any of the other Offering Documents, (ii) any breach of any covenant, agreement or obligation of the Company or any Subsidiary contained in this Agreement or in any of the other Offering Documents, (iii) the execution, delivery, performance or enforcement of this Agreement or any of the other Offering Documents, (iv) any transaction financed or to be financed in whole or in part, directly or indirectly, with the proceeds of the issuance of the Securities, (v) any untrue statement or alleged untrue statement of a material fact contained in any SEC Document or in any Offering Document, or any amendment thereto, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, (vi) the status of such Placement Agent Indemnified Party as a holder of any of the Securities, or as a party (or agent or attorney of such party) to this Agreement or any of the other Offering Documents, (vii) any act or failure to act by any Placement Agent Indemnified Party in connection with, or relating in any manner to, the Securities, the Offering or any of the transactions contemplated by this Agreement or any of the other Offering Documents, provided that the Company shall not be liable under this clause (vii) to the extent that a court of competent jurisdiction shall have determined by a final, non-appealable judgment that such claim, action, cause of action, suit, proceeding, investigation, damage, loss, liability or expense resulted from the gross negligence, bad faith or willful misconduct of such Placement Agent Indemnified Party; and to reimburse such Placement Agent Indemnified Party for any and all expenses (including the reasonable fees and disbursements of counsel chosen by such Placement Agent Indemnified Party) incurred by such Placement Agent Indemnified Party in connection with investigating, defending, settling, compromising or paying any such claim, action, cause of action, suit, proceeding, investigation, damage, loss, liability or expense. To the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of the indemnified liabilities which is permissible under applicable law as provided in Section 8(d).

(b) Notifications and Other Indemnification Procedures. Promptly after receipt by a Placement Agent Indemnified Party under this Section 8 of notice of the commencement of any action, such Placement Agent Indemnified Party will, if a claim in respect thereof is to be made against the Company under this Section 8, notify the Company in writing of the commencement thereof, but the omission so to notify the Company will not relieve it from any liability that it may have to any Placement Agent Indemnified Party for contribution to the extent it is not prejudiced as a proximate result of such failure. In case any such action is brought against any Placement Agent Indemnified Party and the such Placement Agent Indemnified Party seeks or intends to seek indemnity from the Company, the Company shall assume the defense thereof with counsel reasonably satisfactory to such Placement Agent Indemnified Party; provided, however, if the defendants in any such action include both the Placement Agent Indemnified Party and the Company, and the Placement Agent Indemnified Party shall have reasonably concluded on the advice of its counsel that a conflict may arise between the positions of the Company and the Placement Agent Indemnified Party in conducting the defense of any such action or that there may be legal defenses available to it and/or other Placement Agent Indemnified Parties that are different from or additional to those available to the Company, such Placement Agent Indemnified Party or Placement Agent Indemnified Parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such Placement Agent Indemnified Party or Placement Agent Indemnified Parties. Upon receipt of notice from the Company to the Placement Agent Indemnified Party of the Company's assumption the defense of such action and approval by such Placement Agent Indemnified Party of counsel, the Company will not be liable to such Placement Agent Indemnified Party under this Section 8 for any legal or other expenses subsequently incurred by such Placement Agent Indemnified Party in connection with the defense thereof unless: (i) the Placement Agent Indemnified Party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that the Company shall not be liable for the expenses of more than one separate counsel (together with local counsel), approved by the Company), representing the Placement Agent Indemnified Parties who are parties to such action; (ii) the Company shall not have employed counsel satisfactory to the Placement Agent Indemnified Party to represent the Placement Agent Indemnified Party within a reasonable time after notice of commencement of the action; or (iii) the Company has authorized the employment of counsel for the Placement Agent Indemnified Party at the expense of the Company, in each of which cases the fees and expenses of counsel shall be at the expense of the Company.

(c) Settlements. The Company shall not be liable under this Section 8 for any settlement of any proceeding effected without its written consent, which consent shall not be unreasonably conditioned, withheld or delayed, but if settled with such consent or if there be a final judgment for the plaintiff, the Company agrees to indemnify the applicable Placement Agent Indemnified Party or Placement Agent Indemnified Parties against any claim, action, cause of action, suit, proceeding, investigation, damage, loss, liability or expense by reason of such settlement or judgment. The Company shall not, without the prior written consent of the Placement Agent Indemnified Party, effect any settlement, compromise or consent to the entry of judgment in any pending or threatened action, suit or proceeding in respect of which any Placement Agent Indemnified Party is or could have been a party and indemnity was or could have been sought hereunder by such Placement Agent Indemnified Party, unless such settlement, compromise or consent includes: (i) an unconditional release of such Placement Agent Indemnified Party from all liability on claims that are the subject matter of such action, suit or proceeding; 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 any Placement Agent Indemnified Party.

(d) Contribution. If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless a Placement Agent Indemnified Party under Section 8(a) above in respect of any claim, action, cause of action, suit, proceeding, investigation, damage, loss, liability or expense, then the Company shall contribute to the aggregate amount paid or payable by such Placement Agent Indemnified Party in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and such Placement Agent Indemnified Party, on the other, from the Offering. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law then the Company shall contribute to such amount paid or payable by such Placement Agent Indemnified Party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company, on the one hand, and such Placement Agent Indemnified Party, on the other, in connection with the actions or omissions which resulted in such losses, claims, damages or liabilities (or actions or proceedings in respect thereof), as well as any other relevant equitable considerations. The relative fault shall be determined by reference to, among other things, the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such action or omission.

The Company and Placement Agent agree that it would not be just and equitable if contributions 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 above in this Section 8(d). The amount paid or payable by a Placement Agent Indemnified Party as a result of the losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to above in this Section 8(d) shall be deemed to include any legal or other expenses reasonably incurred by such Placement Agent Indemnified Party in connection with investigating or defending any such claim, action, cause of action, suit, proceeding or investigation. Notwithstanding the provisions of this subsection (d): (i) the Placement Agent shall not be required to contribute any amount in excess of the amount of the Cash Fee actually received by Placement Agent pursuant to this Agreement; and (ii) 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.

(e) Timing of Any Payments of Indemnification. Any losses, claims, damages, liabilities or expenses for which a Placement Agent Indemnified Party is entitled to indemnification or contribution under this Section 8 shall be paid by the Company to the Placement Agent Indemnified Party as such losses, claims, damages, liabilities or expenses are incurred, but in all cases, no later than fifteen (15) days of invoice to the Company.

(f) Acknowledgements of Parties. The parties to this Agreement hereby acknowledge that they are sophisticated business persons who were represented by counsel during the negotiations regarding the provisions hereof including, without limitation, the provisions of this Section 8, and are fully informed regarding said provisions. They further acknowledge that the provisions of this Section 8 fairly allocate the risks in light of the ability of the parties to investigate the Company and its business in order to assure that adequate disclosure is made in the Disclosure Package.

Section 9. Representations and Indemnities to Survive Delivery.

The respective indemnities, agreements, representations, warranties and other statements of the Company or any of its Subsidiaries set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of: (i) any investigation made by or on behalf of any Placement Agent Indemnified Party or any of their respective representatives or agents; (ii) acceptance of any Securities and payment therefor; and (iii) any termination of this Agreement or expiration of the Offering Period. A successor to any Placement Agent Indemnified Party shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in Section 8.
