The Company understands and confirms that each Purchaser will rely on the representations and covenants contained herein in effecting the transactions contemplated by this Agreement and the Transaction Documents, and in the securities of the Company after the Closing. All disclosure provided to the Purchasers regarding the Company, its business and the transactions contemplated hereby, including the Schedules to this Agreement furnished by or on behalf of the Company, taken as a whole is true and correct and does not contain any untrue statement of material fact or omit to state any material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading.

The Company acknowledges and agrees that no Purchaser makes or has made any representations or warranties with respect to the transactions contemplated hereby other than those specifically set forth in Section 4.

Each Purchaser represents and warrants, severally (as to itself) and not jointly, to the Company as follows:

When executed and delivered, each of this Agreement and the Registration Rights Agreement will constitute the legal, valid and binding obligation of such Purchaser, enforceable against such Purchaser in accordance with its terms, except as such may be limited by bankruptcy, insolvency, reorganization or other laws affecting creditors’ rights generally and by general equitable principles.

4.5 No Conflict. The execution and delivery of this Agreement and the Registration Rights Agreement by such Purchaser, and the consummation of the transactions contemplated hereby and thereby, will not conflict with or result in any violation of or default by such Purchaser (with or without notice or lapse of time, or both) under any provision of the organizational documents of such Purchaser.

The Company shall cause its counsel to issue a legal opinion to the Company’s transfer agent promptly upon the occurrence of any of the events in clauses (i), (ii) or (iii) above to effect the removal of the legend on certificates evidencing the Shares and shall also cause its counsel to issue a “blanket” legal opinion to the Company’s transfer agent promptly after the effective date of any registration statement covering the resale of Shares, if required by the Company’s transfer agent, to allow sales without restriction pursuant to an effective registration statement. The Company agrees that at such time as such legend is no longer required under this Section 6.2(b), it will, no later than three (3) Business Days following the delivery by a Purchaser to the Company or the Company’s transfer agent of a certificate representing the Shares issued with a restrictive legend, deliver or cause to be delivered to such Purchaser a certificate representing such Shares that is free from all restrictive and other legends; provided that in the case of removal of the legend for reasons set forth in clause (ii) above, the holder of such Shares has submitted a written request to the Company for removal of the legend indicating that the holder has complied with the applicable provisions of Rule 144.

7.2 Claims. All claims for indemnification by a Purchaser Indemnitee pursuant to this Section 7 shall be made as follows:

(a) If a Purchaser Indemnitee has incurred or suffered Losses for which it is entitled to indemnification under this Section 7, then such Purchaser Indemnitee shall give prompt written notice of such claim (a “Claim Notice”) to the Company. Each Claim Notice shall state the amount of claimed Losses (the “Claimed Amount”), if known, and the basis for such claim.

(b) Within 30 days after delivery of a Claim Notice, the Company (the “Indemnifying Party”) shall provide to each Purchaser Indemnitee (the “Indemnified Party”), a written response (the “Response Notice”) in which the Indemnifying Party shall: (i) agree that all of the Claimed Amount is owed to the Indemnified Party, (ii) agree that part, but not all, of the Claimed Amount (the “Agreed Amount”) is owed to the Indemnified Party, or (iii) contest that any of the Claimed Amount is owed to the Indemnified Party. The Indemnifying Party may contest the payment of all or a portion of the Claimed Amount only based upon a good faith belief that all or such portion of the Claimed Amount does not constitute Losses for which the Indemnified Party is entitled to indemnification under this Section 7. If no Response Notice is delivered by the Indemnifying Party within such 30-day period, then the Indemnifying Party shall be deemed to have agreed that all of the Claimed Amount is owed to the Indemnified Party.

(c) If the Indemnifying Party in the Response Notice agrees (or is deemed to have agreed) that all of the Claimed Amount is owed to the Indemnified Party, then the Indemnifying Party shall owe to the Indemnified Party an amount equal to the Claimed Amount to be paid in the manner set forth in this Section 7. If the Indemnifying Party in the Response Notice agrees that part, but not all, of the Claimed Amount is owed to the Indemnified Party, then the Indemnifying Party shall owe to the Indemnified Party an amount equal to the agreed amount set forth in such Response Notice to be paid in the manner set forth in this Section 7. The parties agree that the foregoing shall not be deemed to provide that the Indemnifying Party is entitled to make a binding determination regarding any disputed amounts owed to an Indemnified Party, unless such Indemnified Party accepts and agrees to such determination, and both the Indemnified Party and Indemnifying Party shall retain all rights and remedies available to such party hereunder.

(d) No delay on the part of the Indemnified Party in notifying the Indemnifying Party shall relieve the Indemnifying Party of any liability or obligation hereunder except to the extent of any actual prejudice caused by or arising out of such delay.

7.3 Payment of Claims. An Indemnifying Party shall make payment of any portion of any Claimed Amount that such Indemnifying Party has agreed in a Response Notice that it owes to an Indemnified Party, or that such Indemnifying Party is deemed to have agreed it owes to such Indemnifying Party, said payment to be made within thirty (30) days after such Response Notice is delivered by such Indemnifying Party or should have been delivered by such Indemnifying Party, as the case may be.

7.4 Applicability; Exclusivity. Notwithstanding any term to the contrary in this Section 7, the indemnification and contribution provisions of the Registration Rights Agreement shall govern any claim made with respect to registration statements filed pursuant thereto or sales made thereunder. The parties hereby acknowledge and agree that in addition to remedies of the parties hereto in respect of any and all claims relating to any breach or purported breach of any representation, warranty, covenant or agreement that is contained in this Agreement pursuant to the indemnification provisions of this Section 7, all parties shall always retain the right to pursue and obtain injunctive relief in addition to any other rights or remedies hereunder.
