The Company acknowledges and agrees that each of the Purchasers makes no representations or warranties with respect to the transactions contemplated hereby other than those specifically set forth in this Section 2.2. ARTICLE III OTHER AGREEMENTS OF THE PARTIES 3.1 TRANSFER RESTRICTIONS. (a) Securities may only be disposed of pursuant to an effective registration statement under the Securities Act, to the Company or pursuant to an available exemption from or in a transaction not subject to the registration requirements of the Securities Act. In connection with any transfer of Securities other than pursuant to an effective registration statement or to the Company, except as otherwise set forth herein, the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the transferor, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Securities under the Securities Act. Notwithstanding the foregoing, the Company, without requiring a legal opinion as described in the immediately preceding sentence, hereby consents to and agrees to register on the books of the Company and with any transfer agent for the securities of the Company any transfer of Securities by a Purchaser to an Affiliate of such Purchaser or to one or more funds or managed accounts under common management with such Purchaser, and any transfer among any such Affiliates or one or more funds or managed accounts, provided that the transferee certifies to the Company that it is an "accredited investor" as defined in Rule 501(a) under the Securities Act and that it is acquiring the Securities solely for investment purposes (subject to the qualifications hereof). Any such transferee shall agree in writing to be bound by the terms of this Agreement and shall have the rights of a Purchaser under this Agreement and the Registration Rights Agreement. (b) The Purchasers agree to the imprinting, so long as is required by this Section 3.1(b), of the following legend on the Securities: NEITHER THESE SECURITIES NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE [CONVERTIBLE] [EXERCISABLE] HAVE BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS. -10- Underlying Shares shall not contain the legend set forth above nor any other legend if the conversion of Debentures, the payment of interest thereon, and exercise of the Warrants or other issuances of Underlying Shares as contemplated hereby, by the Debentures or the Warrants occurs at any time while an Underlying Shares Registration Statement is effective under the Securities Act or, in the event there is not an effective Underlying Shares Registration Statement, at such time, in the opinion of counsel to the Company, such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission). The Company shall cause its counsel to issue the legal opinion included in the Transfer Agent Instructions to the Company's transfer agent on the day that the Underlying Shares Registration Statement is declared effective by the Commission. The Company agrees that, in the event any Underlying Shares are issued with a legend in accordance with this Section 3.1(b), it will, within three (3) Trading Days after request therefor by a Purchaser, provide such Purchaser with a certificate or certificates representing such Underlying Shares, free from such legend at such time as such legend would not have been required under this Section 3.1(b) had such issuance occurred on the date of such request. The Company may not make any notation on its records or give instructions to any transfer agent of the Company which enlarge the restrictions of transfer set forth in this Section. However, the Company may provide appropriate instructions to any transfer agent of the Company to enforce the provisions of this Section 3.1(b) when the Underlying Shares Registration Statement is not effective. 3.2 ACKNOWLEDGMENT OF DILUTION. The Company acknowledges that the issuance of the Underlying Shares upon (i) conversion of the Debentures and payment of interest thereon in accordance with the terms of the Debentures, and (ii) exercise of the Warrants in accordance with their terms, will result in dilution of the outstanding shares of Common Stock, which dilution may be substantial under certain market conditions. The Company further acknowledges that its obligation to issue Underlying Shares upon (x) conversion of the Debentures and payment of interest thereon in accordance with the terms of the Debentures, and (y) exercise of the Warrants in accordance with their terms, is unconditional and absolute, subject to the limitations set forth herein in the Debentures or pursuant to the Warrants, regardless of the effect of any such dilution. 3.3 FURNISHING OF INFORMATION. As long as the Purchasers own Securities, the Company covenants to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Section 13(a) or 15(d) of the Exchange Act. As long as the Purchasers own Securities, if the Company is not required to file reports pursuant to such sections, it will prepare and furnish to the Purchasers and make publicly available in accordance with Rule 144(c) promulgated under the Securities Act such information as is required for the Purchasers to sell the Securities under Rule 144 promulgated under the Securities Act. The Company further covenants that it will take such further action as any holder of Securities may reasonably request, all to the extent required from time to time to enable such Person to sell Underlying Shares without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act, including the legal opinion referenced above in this Section. Upon the request of any such Person, the Company shall deliver to such Person a written certification of a duly authorized officer as to whether it has complied with such requirements. -11- 3.4 INTEGRATION. The Company shall not, and shall use its best efforts to ensure that, no Affiliate of the Company shall, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Securities in a manner that would require the registration under the Securities Act of the sale of the Securities to the Purchasers. 3.5 INCREASE IN AUTHORIZED SHARES.

(b) The Company shall maintain a reserve of shares of Common Stock for issuance upon conversion of the Debentures and for payment of interest thereupon in shares of Common Stock and upon exercise in full of the Warrants in accordance with this Agreement, the Debentures and the Warrants, respectively, in such amount as may be required to fulfill its obligations in full under the Transaction Documents, which reserve shall equal no less than the then Current Required Minimum. 3.7 CONVERSION AND EXERCISE PROCEDURES.
