5. Representations and Warranties of the Purchaser. As a material inducement for the Company’s issuance and sale of the Shares, the Warrant and any Warrant Shares, the Purchaser represents, warrants, covenants and acknowledges to the Company that:

(a) The Purchaser understands that the issuance of the Shares and the Warrant has not been, and any issuance of the Warrant Shares will not be, registered under the Securities Act, or applicable state securities laws. Instead, the Company is issuing the Shares and the Warrant, and will issue any Warrant Shares, pursuant to exemptions from such laws and in doing so is and would be relying on, among other things, the Purchaser’s representations, warranties, covenants and acknowledgements contained herein.

(b) The Purchaser qualifies as an “accredited investor” as such term is defined in Rule 501(a) of Regulation D under the Securities Act.

(c) The Purchaser has sufficient knowledge of the Company’s business, financial condition and prospects. In addition, the Purchaser has been provided with or given access to such additional information as the Purchaser has requested, including access to the Company’s management, and has utilized such access to his satisfaction for the purpose of obtaining information regarding the Company’s business, financial condition and prospects.

(d) The Purchaser is acquiring the Shares and the Warrant, and will acquire any Warrant Shares, for its own account, for investment purposes only, and without the intention of reselling or redistributing the Shares or any Warrant Shares, except that the Purchaser may transfer the Shares and/or the Warrant to an affiliate of the Purchaser;

(e) The Purchaser is aware that, in the view of the Securities and Exchange Commission, a purchase of the Shares, the Warrant or any Warrant Shares with an intent to resell by reason of any foreseeable specific contingency or anticipated change in market values, or any change in the Company’s condition, or in connection with a contemplated liquidation or settlement of any loan obtained for the acquisition of the Shares, the Warrant or any Warrant Shares and for which the Shares, the Warrant or any Warrant Shares were pledged, would constitute an intent inconsistent with the foregoing representation.

(f) If, contrary to the Purchaser’s foregoing intentions, it should later desire to dispose of or transfer any of the Shares, the Warrant or any Warrant Shares in any manner, the undersigned shall not do so without (i) first obtaining an opinion of counsel satisfactory to the Company that such proposed disposition or transfer may lawfully be made without registration pursuant to the Securities Act and applicable state securities laws or (ii) registering the resale of the Shares and any Warrant Shares under the Securities Act and applicable state securities laws.

(g) Except as otherwise provided in the Warrant or in the Registration Rights Agreement, dated as of the date hereof, between the Company and the Purchaser (the “Registration Rights Agreement”), the Company has no obligation to register the Shares, the Warrant or any Warrant Shares for resale under the Securities Act or any applicable state securities laws, or to take any other action which would facilitate the availability of federal or state registration exemptions in connection with any resale of the Shares, the Warrant or any Warrant Shares. Accordingly, the Purchaser may be prohibited by law from selling or otherwise transferring or disposing of the Shares, the Warrant or any Warrant Shares and may have to bear the economic risk of its investment in the Company for an indefinite period.

(h) Purchaser understands its obligations regarding the restriction on trading in the Company’s securities while in possession of material nonpublic information.
