3.             Representations, Warranties and Covenants of the Company.  The Company hereby represents and warrants to, and covenants with, the Investor, as follows:

3.1           The issuance and sale of each of the Offered Shares and the Offered Warrants have been duly authorized by the Company, and the Offered Shares, when issued and paid for in accordance with this Agreement, will be duly and validly issued, fully paid and nonassessable and will not be subject to preemptive or similar rights.  The Warrant Shares have been duly authorized and reserved for issuance pursuant to the terms of the Offered Warrants, and the Warrant Shares, when issued by the Company upon valid exercise of the Offered Warrants and payment of the exercise price, will be duly and validly issued, fully paid and nonassessable and will not be subject to preemptive or similar rights.

3.2           Each of this Agreement and the Warrants constitutes a valid and binding obligation of the Company enforceable against the Company in accordance with its terms, subject to the effect of applicable bankruptcy, insolvency or similar laws affecting creditors’ rights generally and equitable principles of general applicability.

3.3           For a period of 60 days from the date hereof, the Company shall not offer or sell any equity or equity-related securities in any public or private offering to one or more institutional investors without the Investor’s prior written consent, which, for the sake of clarity, will not preclude the Company from, among other things: (i) the offer or sale of the Offered Securities to the Investor as contemplated hereby; (ii) the offer or sale of equity or equity-related securities pursuant to benefit plans for the benefit of the Company’s officers, directors, employees or consultants; (iii) the offer or sale of equity or equity-related securities pursuant to any shareholder rights plan of the Company; or (iv) the offer or sale of equity or equity-related securities as part of a strategic collaboration, license, partnership, venture or similar transaction.
