Except as set forth in the Financial Statements filed prior to the date hereof, the Company has not incurred any liabilities, contingent or otherwise, except those incurred in the ordinary course of business, since the date of such Financial Statements, none of which, individually or in the aggregate, have had or would reasonably be expected to have a Material Adverse Effect.

Any preclinical tests and studies or clinical trials conducted by, on behalf of, or sponsored by the Company or any of its subsidiaries (“Studies”), were and, if still pending, are being conducted in all material respects in accordance with all applicable laws and regulations governing the conduct of such Studies, the protocols submitted to the FDA or any foreign governmental body exercising comparable authority (together with the FDA, the “Regulatory Authorities”), and any conditions of approval and policies imposed by any institutional review board, ethics review board or committee responsible for the oversight of such Studies. The descriptions of the Studies contained in the SEC Documents are accurate in

Neither such inquiries nor any other due diligence investigation conducted by such Purchaser shall modify, limit or otherwise affect such Purchaser’s right to rely on the Company’s representations, warranties and covenants contained in this Agreement.

The Company shall pay all fees and expenses in connection with satisfying its obligations under this Section 7.1. The Company agrees, if the Company applies to have the Common Stock traded on any other exchange or market, it will then include in such application all of the Shares, and will use its best efforts to take such other action as is necessary to cause all of the Shares to be listed or quoted on such other exchange or market as promptly as possible.

7.3 Indemnification.

(a) The Company agrees to indemnify and hold harmless each Purchaser and its Affiliates, and their respective directors, officers, trustees, members, managers, employees, investment advisers and agents (the “Indemnified Parties”), from and against any and all losses, claims, damages, liabilities and expenses (including without limitation reasonable and documented attorney fees and disbursements and other documented out-of-pocket expenses reasonably incurred in connection with investigating, preparing or defending any action, claim or proceeding, pending or threatened and the costs of enforcement thereof) to which such Person may become subject as a result or arising out of (i) any breach of representation, warranty, covenant or agreement made by or to be performed on the part of the Company under this Agreement, or (ii) any action or claim instituted or made against an Indemnified Party in any capacity, by an stockholder or the Company or any third party who is not an Affilaite of such Indemnified Party, in each case whether directly or directly or in a derivative capacity, with respect to any of the transactions contemplated by this Agreement (unless such action is solely based upon a breach of such Indemnified Party’s representations, warranties or covenants under this Agreement), and the Company will reimburse any such Person for all such amounts as they are incurred by such Person, solely to the extent such amounts have been finally judicially determined not to have resulted from such Person’s fraud or willful misconduct.

(b) Any person entitled to indemnification hereunder shall (a) give prompt written notice to the Company of any claim with respect to which it seeks indemnification and (b) permit the Company to assume the defense of such claim with counsel reasonably satisfactory to the Indemnified Party; provided that any person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such person unless (i) the Company has agreed in writing to pay such fees or expenses, (ii) the Company shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such person or (iii) in the reasonable judgment of any such person, based upon written advice

It is understood that the Company shall not, in connection with any proceeding in the same jurisdiction, be liable for fees or expenses of more than one separate firm of attorneys at any time for all such Indemnified Parties. The Company shall not, without the prior written consent of the Indemnified Party, which consent shall not be unreasonably withheld, conditioned or delayed, consent to entry of any judgment or enter into any settlement or other compromise that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect of such claim or litigation and such settlement shall not include any admission as to fault on the part of the Indemnified Party. No Indemnified Party will, except with the consent of the Company, which consent shall not be unreasonably withheld, conditioned or delayed, consent to entry of any judgment or enter into any settlement.

17

Following the Disclosure Time, no Purchaser shall be in possession of any material non-public information received from the Company, its subsidiaries or any of their respective officers, directors, employees or agents, and the Company covenants and agrees that neither it, nor any other Person acting on its behalf, will provide any Purchaser or its agents or counsel with any information that constitutes, or the Company reasonably believes constitutes, material non-public information, unless prior thereto such Purchaser shall have consented to the receipt of such information and agreed with the Company through the Purchaser’s internal or “wall cross” procedures or otherwise pursuant to an obligation of such Purchaser to keep such information confidential. No press release or, except to the extent required under applicable law, other public announcement shall be made, directly or indirectly, by any party hereto concerning the execution of this Agreement, the terms and conditions hereof or the consummation of the transactions contemplated hereby, in each case without the prior written consent of the other party hereto. Notwithstanding the foregoing, the Company may issue the Disclosure Document (after providing the Purchasers an opportunity to review and comment on such Disclosure Document, it being understood that identity of the Purchasers will be disclosed in the Agreement included as an exhibit to the Disclosure Document). The Company shall not include the name of any of the Purchasers or their respective Affiliates or advisers in any filing, press release (including the Disclosure Document), announcement or otherwise without the prior written consent of such Purchaser, except if such disclosure is required by law, rule, regulation or applicable Commission guidance, in which case the Company shall provide such Purchaser with prompt prior notice of such requirement so that such Purchaser may (a) seek appropriate relief to prevent or limit such disclosure, (b) furnish only that portion of the information which is legally required to be furnished or disclosed, and to the extent reasonably feasible, and (c) consult with the Company on content and timing prior to any such disclosure. Each Purchaser, severally and not jointly with the other Purchasers, covenants that, until such time as the transactions contemplated by this Agreement are required to be publicly disclosed by the Company as described in this Section 9.14, such Purchaser will maintain the confidentiality of all disclosures made to it in connection with this transaction (including the existence and terms of this transaction). Notwithstanding the foregoing, no Purchaser shall be restricted or prohibited from effecting any transactions in any securities of the Company in accordance with applicable securities laws from and after the time that the transactions contemplated by this Agreement are publicly disclosed by the Company as described in this Section 9.14, and no Purchaser shall have any duty of confidentiality or duty not to trade in the securities of the Company to the Company after such public disclosure, except as otherwise expressly agreed in writing between the Company and such Purchaser.

18

9.15 Equal Treatment of Purchasers. No consideration (including any modification of this Agreement) shall be offered or paid to any Person to amend or consent to a waiver or modification of any provision of this Agreement unless the same consideration is also offered to all of the parties to such Agreement. For clarification purposes, this provision constitutes a separate right granted to each Purchaser by the Company and negotiated separately by each Purchaser and shall not in any way be construed as the Purchasers acting in concert or as a group with respect to the purchase, disposition or voting of Common Stock or otherwise.
