(b) Limitation on Right of First Refusal. Notwithstanding anything to the contrary contained herein, the number of shares of Common Stock that may be acquired directly or through acquisition of Common Stock Equivalents by the Purchaser pursuant to any transaction to which this Section 6.3 applies shall not exceed a number that, when added to the total number of shares of Common Stock deemed beneficially owned by the Purchaser (other than by virtue of the ownership of securities or rights to acquire securities (including the Note and the Warrant) that have limitations on the Purchaser’s right to convert, exercise or purchase similar to the limitation set forth herein (the “Excluded Shares”)), together with all shares of Common Stock deemed beneficially owned at such time (other than by virtue of ownership of Excluded Shares) by Persons whose beneficial ownership of Common Stock would be aggregated with the beneficial ownership of the Purchaser for purposes of determining whether a group exists or for purposes of determining the Purchaser’s beneficial ownership in either case for purposes of Section 13(d) of the 1934 Act and Regulation 13D-G thereunder, would result in beneficial ownership by the Purchaser or such group of more than 9.9% of the shares of the Company’s Common Stock (the “Restricted Ownership Percentage”), computed in accordance with Regulation 13D-G. The Purchaser shall have the right at any time and from time to time to reduce its Restricted Ownership Percentage immediately upon notice to the Company in the event and only to the extent that Section 16 of the 1934 Act or the rules promulgated thereunder

and such legend as may be required by the authorities of any state in connection with the qualification of the Underlying Shares and the Warrant Shares for sale, or exemption therefrom, in such state. Upon registration for resale pursuant to the Registration Rights Agreement or, in the absence of such registration, upon Rule 144(k) under the 1933 Act becoming available, the Company shall promptly (but in no event later than five Business Days after surrender of the legended certificates to the Company) cause certificates evidencing the Underlying Shares and Warrant Shares previously issued to be replaced with certificates which do not bear the restrictive legends specified above in this Section 6.11, and all Underlying Shares and Warrant Shares subsequently issued shall not bear the restrictive legend specified above in this Section 6.11. If the Purchaser notifies the Company that, within three Business Days after surrender of such legended certificates, the Purchaser has not received such certificates without such restrictive legends (each, a “Purchaser Share Notice”), and the Purchaser does not receive such certificates without such restrictive legends within two Business Days after giving a particular Purchaser Share Notice, then the Company shall pay partial liquidated damages to the Purchaser in cash on demand, calculated at the rate of 1% per month of the original Purchase Price of the Note in respect of which such Underlying Shares are issuable or issued, and the purchase price paid upon exercise of the Warrant in respect of which such Warrant shares are issuable or issued, and in any such case for which the certificates have not been provided in compliance with the above, for each day so long as the Company fails to provide such certificates. Notwithstanding the foregoing the Company shall not be liable to the Purchaser for such partial liquidated damages to the extent the failure of the Company to deliver or to cause to be delivered the unlegended securities results from fire, flood, storm, earthquake, shipwreck, strike, war, acts of terrorism, crash involving facilities of a common carrier, acts of God, or any similar event outside the control of the Company (it being understood that the action or failure to act of the Company’s Transfer Agent shall not be deemed an event outside the control of the Company except to the extent resulting from fire, flood, storm, earthquake, shipwreck, strike, war, acts of terrorism, crash involving facilities of a common carrier, acts of God, or any similar event outside the control of such Transfer Agent or the bankruptcy, liquidation or reorganization of such Transfer Agent under any bankruptcy, insolvency or other similar law). The Purchaser agrees that any sale by the Purchaser of Underlying Shares and Warrant Shares pursuant to the Registration Statement shall be sold in a manner described under the caption “Plan of Distribution” in such Registration Statement and (A) if such sale is made through a broker, the Purchaser shall instruct such broker to deliver the Prospectus to the purchaser or purchasers (or the broker or brokers therefore) in connection with such sale, shall supply copies of the

- 22 -

Prospectus to such broker or brokers and shall instruct such broker or brokers to deliver such Prospectus to the purchaser in such sale or such purchaser’s broker, (B) if such sale is made in a transaction directly with a purchaser and not through the facilities of any securities exchange or market, the Purchaser shall deliver, or cause to be delivered, the Prospectus to such purchaser; and (C) if such sale is made by any means other than those described in the immediately preceding clauses (A) and (B), the Purchaser shall otherwise comply with the prospectus delivery requirements of the 1933 Act applicable to such sale. The Purchaser acknowledges that the removal of the restrictive legends from certificates representing Underlying Shares and Warrant Shares as provided in this Section 6.11 is predicated upon the Company’s reliance on the Purchaser’s compliance with its covenants in this Section 6.11.

6.12 Limitation on Certain Actions. From the date of execution and delivery of this Agreement by the parties hereto to the date of issuance of the Note, the Company (1) shall comply with Section 4 of the Note as if the Note were outstanding, (2) shall not take any action which, if the Note were outstanding, (A) would constitute an Event of Default or, with the giving of notice or the passage of time or both, would constitute an Event of Default or (B) would constitute a Repurchase Event or, with the giving of notice or the passage of time or both, would constitute a Repurchase Event.

6.13 Reasonable Best Efforts. Each of the parties shall use its reasonable best efforts timely to satisfy each of the conditions to the other party’s obligations to sell and purchase the Note and Warrant set forth in Section 7.1 or 7.2, as the case may be, of this Agreement on or before the Closing Date.

6.14 Debt Obligation. So long as any portion of the Note is outstanding, the Company shall cause its books and records to reflect the Note as a debt of the Company in its unpaid principal amount, shall cause its financial statements to reflect the Note as a debt of the Company in such amount as shall be the greatest amount permitted in accordance with Generally Accepted Accounting Principles and as a valid senior debt obligation of the Company for money borrowed.

6.15 Limitation on Material Non-Public Information. Notwithstanding anything to the contrary contained in this Agreement, the Company shall not disclose material nonpublic information to the Purchaser, or to advisors to or representatives of the Purchaser, unless prior to disclosure of such information the Company identifies such information as being material nonpublic information and provides the Purchaser, such advisors and representatives with the opportunity to accept or refuse to accept such material nonpublic information for review. The Company may, as a condition to disclosing any material nonpublic information hereunder, require the Purchaser’s advisors and representatives to enter into a confidentiality agreement (including an acknowledgement by such advisors and representatives as to their legal obligations regarding trading in Common Stock during such period of time as they are in possession of material nonpublic information) in form reasonably satisfactory to the Company and the Purchaser.
