collectively, the “Shares”) of its common stock, par value $0.001 per share (the “Common Stock”), and (ii) warrants (“Warrant,”
collectively, the “Warrants”) to purchase      shares of Common Stock
(and the fractional amount being the “Warrant Ratio”), subject to adjustment by the Company’s Board

     4. The Company and the Investor agree that the Investor will purchase from the Company and the
Company will issue and sell to the Investor the Units set forth below for the aggregate purchase
price set forth below. The Units shall be purchased pursuant to the Terms and Conditions for

permit an offering of the Units, or possession or distribution of offering materials in connection

purpose is required. Each Investor outside the United States will comply with all applicable laws
and regulations in each foreign jurisdiction in which it purchases, offers, sells or delivers Units

and binding obligation of the Investor enforceable against the Investor in accordance with its
terms, except as enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting creditors’ and contracting parties’ rights
generally and except as enforceability may be subject to general principles of equity (regardless
of whether such enforceability is considered in a proceeding in equity or at law) and except as the
indemnification agreements of the Investors herein may be legally unenforceable.




          4.4 The Investor understands that nothing in this Agreement, the Prospectus or any other
materials presented to the Investor in connection with the purchase and sale of the Units
constitutes legal, tax or investment advice. The Investor has consulted such legal, tax and
investment advisors as it, in its sole discretion, has deemed necessary or appropriate in
connection with its purchase of Units.




          4.5 Each Investor represents, warrants and agrees that, since the earlier to occur of (i) the

covenants that it will not engage in any transactions in the securities of the Company (including
Short Sales) prior to the time that the transactions contemplated by this Agreement have been
consummated and are publicly disclosed. Each Investor agrees that it will not use any of the Units
acquired pursuant to this Agreement to cover any short position in the Common Stock if doing so
would be in violation of applicable securities laws. For purposes hereof, “Short Sales” include,
without limitation, all “short sales” as defined in Rule 200 promulgated under Regulation SHO under

pledges, forward sales contracts, options, puts,
