C. Representations and Warranties of Purchaser. Purchaser hereby represents and warrants as of each Closing as follows:

1. Organization; Authority. Purchaser has the full right, power and authority to enter into and to consummate the transactions contemplated by the Transaction Documents and otherwise to carry out its obligations thereunder.

Purchaser, either alone or together with its representatives, has such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Securities, and has so evaluated the merits and risks of such investment. Purchaser is able to bear the economic risk of an investment in the Securities and, at the present time, is able to afford a complete loss of such investment.

IV. Securities Provisions.

A. No Non-Public Information. Company covenants and agrees that neither it nor any other Person acting on its behalf will, provide Purchaser or its agents or counsel with any information that Company believes or reasonably should believe constitutes material non-public information. On and after the Effective Date, neither Purchaser nor any Affiliate of Purchaser will have any duty of trust or confidence that is owed directly, indirectly, or derivatively, to Company or the stockholders of Company, or to any other Person who is the source of material non-public information regarding Company. Company understands and confirms that Purchaser will be relying on the foregoing in effecting transactions in securities of Company, including without limitation sales of the Securities.

B. Reservation of Shares. Company shall maintain a reserve from its duly authorized Common Stock for issuance pursuant to the Transaction Documents authorized shares

of Common Stock in an amount sufficient to immediately issue all shares of Common Stock potentially issuable upon any conversion of the Preferred Shares.

C. Ownership Restrictions. Company and the Purchaser agree that, notwithstanding any other provision in this Agreement or the Certificate of Designations, at no time may the Preferred Shares be converted if the number of shares of Common Stock to be received by the Purchaser pursuant to such conversion, when aggregated with all other shares of Common Stock then beneficially (or deemed beneficially) owned by the Purchaser, would result in the Purchaser beneficially owning more than 9.9% of all Common Stock outstanding as determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder.

V. General Provisions.

A. Notice. Unless a different time of day or method of delivery is set forth in the Transaction Documents, any and all notices or other communications or deliveries required or permitted to be provided hereunder will be in writing and will be deemed given and effective on the earliest of: (a) the date of transmission, if such notice or communication is delivered via facsimile or electronic mail prior to 5:00 p.m. Eastern time on a Trading Day and an electronic confirmation of delivery is received by the sender, (b) the next Trading Day after the date of transmission, if such notice or communication is delivered later than 5:00 p.m. Eastern time or on a day that is not a Trading Day, (c) the next Trading Day following the date of mailing, if sent by U.S. nationally recognized overnight courier service, or (d) upon actual receipt by the party to whom such notice is required to be given.

C. Successors and Assigns. This Agreement will be binding upon and inure to the benefit of the parties and their successors and permitted assigns. Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of Purchaser, which consent will not be unreasonably withheld. Purchaser may assign any or all of its rights under this Agreement (a) to any Affiliate, or (b) to any Person to whom Purchaser assigns or

transfers any Securities, provided such transferee agrees to be bound by the provisions hereof with respect to the transferred Securities and Purchaser remains primarily responsible for the performance of its obligations under this Agreement.

F. Severability. If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity and enforceability of the remaining terms and provisions of this Agreement will not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so agreeing, will incorporate such substitute provision in this Agreement.

G. Replacement of Certificates. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, Company will issue or cause to be issued in exchange and substitution for and upon cancellation thereof, or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to Company of such loss, theft or destruction and customary and reasonable indemnity, if requested. The applicants for a new certificate or instrument under such circumstances will also pay any reasonable third-party costs associated with the issuance of such replacement certificates.

All currency references in this Agreement and any Transaction Document refer to U.S. dollars.

M. Execution. This Agreement may be executed in two or more counterparts, all of which when taken together will be considered one and the same agreement and will become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered by portable document format, facsimile or electronic transmission, such signature will create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such signature page were an original thereof.

N. Entire Agreement. This Agreement, including the Exhibits hereto, which are hereby incorporated herein by reference, contains the entire agreement and understanding of the parties, and supersedes all prior and contemporaneous agreements, term sheets, letters, discussions, communications and understandings, both oral and written, which the parties acknowledge have been merged into this Agreement. No party, representative, attorney or agent has relied upon any collateral contract, agreement, assurance, promise, understanding or representation not expressly set forth hereinabove.
