5. Representations and Warranties of the Investor to the Company. Investor represents and warrants to the Company that:

(a) Purchase for Own Account. Investor represents that it is acquiring the Note solely for its own account and beneficial interest for investment and not for sale or with a view to distribution of the Note or any securities issuable upon conversion thereof (“Securities”) or any part thereof, has no present intention of selling (in connection with a distribution or otherwise), granting any participation in, or otherwise distributing the same, and does not presently have reason to anticipate a change in such intention.

(b) Information and Sophistication. Without lessening or obviating the representations and warranties of the Company set forth in Section 4, Investor hereby: (i) acknowledges that it has received all the information it has requested from the Company and it considers necessary or appropriate for deciding whether to acquire the Note, (ii) represents that it has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of the Note and to obtain any additional information necessary to verify the accuracy of the information given to Investor and (iii) further represents that it has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risk of this investment.

(c) Ability to Bear Economic Risk. Investor acknowledges that investment in the Note involves a high degree of risk, and represents that it is able, without materially impairing its financial condition, to hold the Note for an indefinite period of time and to suffer a complete loss of its investment.

(d) Further Limitations on Disposition. Without in any way limiting the representations set forth above, Investor further agrees not to make any disposition of all or any portion of the Securities unless and until:

(i) There is then in effect a registration statement under the Act covering such proposed disposition and such disposition is made in accordance with such registration statement; or

(ii) Investor shall have notified the Company of the proposed disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, and if reasonably requested by the Company, Investor shall have furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that such disposition will not require registration under the Act or any applicable state securities laws, provided that no such opinion shall be required for dispositions in compliance with Rule 144.

(e) Accredited Investor Status. Investor is an “accredited investor” as such term is defined in Rule 501 under the Act.

6. Ownership Limitation. The Company shall not permit any conversion of the Series B Preferred Stock issuable upon conversion of the Note, and the Investor shall not have the right to convert any portion of such Series B Preferred Stock, to the extent that, after giving effect to such conversion, the Investor (together with its affiliates) would beneficially own in excess of 4.99% of the number of shares of Common Stock of the Company outstanding on such date (the “Beneficial Ownership Limitation”) as calculated pursuant to Section 13(d) of the Securities Exchange Act of 1934, as amended, and Rule 13d-3 promulgated thereunder. Upon the written or oral request of the Investor, the Company shall promptly confirm orally or in writing to the Investor the number of shares of Common Stock then outstanding. The Investor and the Company shall each cooperate in good faith in the determinations required hereby and the application hereof. The Investor’s written certification to the Company of the applicability of the Beneficial Ownership Limitation, and the resulting effect thereof hereunder at any time, shall be conclusive with respect to the applicability thereof and such result absent manifest error.
