     SECTION 3. Representations, Warranties and Covenants of the Purchaser. The Purchaser represents and warrants to, and covenants with, the Company that:

     3.1 Experience.

     3.2 Reliance on Exemptions. The Purchaser understands that the Further Additional Shares are being offered and sold to it in reliance upon specific exemptions from the registration requirements of the Securities Act, the Rules and Regulations and state securities laws and that

the Company is relying upon the truth and accuracy of, and the Purchaser’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of the Purchaser set forth herein in order to determine the availability of such exemptions and the eligibility of the Purchaser to acquire the Further Additional Shares.

     3.3 Investment Decision. The Purchaser understands that nothing in the Agreement or any other materials presented to the Purchaser in connection with the purchase and sale of the Further Additional Shares, constitutes legal, tax or investment advice. The Purchaser 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 the Further Additional Shares.

     3.4 Risk of Loss. The Purchaser understands that its investment in the Further Additional Shares involves a significant degree of risk, including a risk of total loss of the Purchaser’s investment, and the Purchaser has full cognizance of and understands all of the risk factors related to the Purchaser’s purchase of the Securities. The Purchaser understands that the market price of the Common Stock into which the Further Additional Shares is convertible has been volatile, and that no representation is being made as to the future value of the Further Additional Shares.

     3.5 Legend. The Purchaser understands that, until such time as a registration statement has been declared effective or the Further Additional Shares may be sold pursuant to Rule 144 under the Securities Act without any restriction as to the number of securities as of a particular date that can then be immediately sold, the Further Additional Shares will bear a restrictive legend in substantially the following form:

“THE SECURITIES REPRESENTED BY THIS INSTRUMENT HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR SECURITIES LAWS OF ANY STATE AND MAY NOT BE TRANSFERRED, SOLD OR OTHERWISE DISPOSED OF EXCEPT WHILE A REGISTRATION STATEMENT RELATING THERETO IS IN EFFECT UNDER SUCH ACT AND APPLICABLE STATE SECURITIES LAWS OR PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT OR SUCH LAWS.

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO TRANSFER AND OTHER RESTRICTIONS SET FORTH IN AN INVESTMENT AGREEMENT, DATED AS OF DECEMBER 17, 2008, COPIES OF WHICH ARE ON FILE WITH THE SECRETARY OF THE ISSUER.”

     3.6 Transfer Restrictions. Consistent with the legend set forth in Section 3.5, the Further Additional Shares may only be disposed of in compliance with state and federal securities laws and the transfer and other restrictions set forth in the Investment Agreement as if they were “Securities” thereunder.
