(c) Agreement Regarding Series C Preferred Stock. Each of the Investors as a holder of Preferred C Shares hereby covenants and agrees that:

(i) Holders of Preferred C Shares shall not have any right to require the Company to redeem Preferred C Shares pursuant to the Series C Documents, and no such holder shall exercise any option in the Series C Documents to require the Company to redeem all or any portion of such Investor’s Preferred C Shares; provided, however, that an Investor shall retain any right under the Series C Documents to elect to cause the Company to redeem Preferred C Shares under the following circumstances:

(A) The Company fails to deliver to an Investor Conversion Shares within 10 days of the Conversion Date on which such Investor satisfied the requirements for conversion of Preferred C Shares, which the Company legally may issue to such Investor; and

(B) The Company redeems or repurchasers any Common Stock or other equity security junior to the Preferred C Shares in contravention of the rights of the Preferred C Shares.

(ii) upon conversion of any Preferred C Shares, the converting Investor shall cause to be returned to the Company for cancellation, or not to be issued, any shares of Common Stock issuable upon such conversion as a result of any Additional Amount (as defined in the Certificate of Amendment) arising after the date hereof.

Each Investor’s proportionate share shall be a fraction, the numerator of which is the amount of Series C Preferred Shares purchased by an Investor from HFTP and the denominator of which is the total amount of Series C Preferred Shares purchased from HFTP by all Investors. The foregoing sales limitation shall not apply to sales effected as per Common Stock prices greater than sixty cents ($.60). The Company may waive the foregoing sales limitation as to all, but not less than all Investors.

the Company or any of its Subsidiaries, threatened against or affecting the Company, the Common Stock or any of the Company’s Subsidiaries or any of the Company’s or the Company’s Subsidiaries’ officers or directors in their capacities as such, which would have a Material Adverse Effect.

(j) Application of Takeover Protections. Assuming that the Investors, including acting in concert with others, have no present intention to exercise control over, takeover or participate in a takeover of the Company, the Company and its board of directors have taken all necessary action, if any, in order to render inapplicable any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or other similar anti-takeover provision under the Certificate of Incorporation or the laws of the state of its incorporation which is or could become applicable to the Investors as a result of the Investors and the Company fulfilling their obligations under this Agreement, including, without limitation, the Company’s issuance of the Securities and the Investors’ ownership of the Securities.

(k) Rights Agreement. Assuming that Investors, including acting in concert with others, have no present intention to exercise control over, takeover or participate in a takeover of the Company and so long as the proviso to the first sentence of Section IV(A) of the Certificate of Amendment remains in full force and effect, the Company specifically represents, warrants and agrees that, (i) in accordance with that certain Rights Agreement dated as of April 23, 1999 (the “Rights Plan”) between the Company and Continental Stock Transfer & Trust Company, as the Rights Agent thereunder, regardless of the number of Conversion Shares of which an Investor is deemed the Beneficial Owner (as defined in the Rights Plan), an Investor is not intended to be nor will be deemed to be an Acquiring Person within the meaning of the Rights Plan because of the acquisition of the Securities pursuant to this Agreement, and (ii) the acquisition of the Securities pursuant to this Agreement, shall not, under any circumstances, trigger a Distribution Date within the meaning of the Rights Plan; provided, however, that only Securities acquired pursuant to this Agreement shall be deemed excluded from the number of shares of Common Stock deemed beneficially owned by Investors in determining whether an Investor is an Acquiring Person within the meaning of the Rights Plan.

(l) Conversion Price. The Company acknowledges and agrees that pursuant to the Certificate of Amendment governing the Series C Preferred Stock, the sale of the shares of Common Stock under this Agreement will cause an adjustment to the Conversion Price of the Preferred C Shares to the sales price for such Purchased Shares to the extent such sales price is less than the applicable Conversion Price immediately prior to the sale of the Purchased Shares.

(m) Holding Period of Preferred C Shares. The Company also acknowledges and agrees that HFTP purchased the Preferred C Shares directly from the Company on October 10, 2000 and has held the Preferred C Shares continuously since such date. The Company further acknowledges and agrees that HFTP has represented to it as of the date hereof that it is not an affiliate of the Company. In addition, the Company has delivered to the Investors, as of the date hereof, the opinion of Anslow & Jaclin, LLP, Freehold, New Jersey to the effect that HFTP is not an affiliate of the Company and the Investors are entitled to tack the holding period of HFTP of the Preferred C Shares sold by HFTP to the Investors to the Investors own holding period for those shares for purposes of the holding period requirements of Rule 144(d) under the 1933 Act. The Company agrees not to take any position contrary to such representation and opinion with respect to the Investors’ holding of the Preferred C Shares.

(n) Conversion Limitations of Series C Preferred Stock. The Company acknowledges that the provisions of the Series C Documents and the Certificate of Amendment of the Certificate of Incorporation setting forth the terms of the Series C Preferred Stock that impose limitations on the amount of Preferred C Shares that may be converted into Common Stock at any time by a holder of Preferred C Shares only apply to each holder, of record or beneficially, of Preferred C Shares and its affiliates, and such a holder is not required to aggregate its ownership of Company securities with the ownership of Company securities by any other holder of Preferred C Shares (not an affiliate of it or acting in concert with it) for purposes of the limitations on conversion of Preferred C Shares into Common Stock by a holder thereof set forth in the Certificate of Amendment; and the Company agrees that it shall not take a position contrary to such application of those conversion limitations. Thus, based on the representations of the Investors in Section 3(h) of this Agreement, none of the Investors would have to aggregate its ownership of Company securities with ownership of such securities of HFTP for purposes of calculating a conversion limitation governing the Preferred C Shares.

(o) The Company acknowledges its obligation in accordance with the Series C Documents to issue shares of its Common Stock upon the conversion of Preferred C Shares by the Investors. As of the transfer of the Preferred C Shares by HFTP to the Investors, there were no defaults in the obligations of a holder of Preferred C Shares which are assumed by the Investors, the rights of the Investors to the rights and obligations of the Preferred C Shares in accordance with the Series C Documents is not impaired in any way, and the Company does not have any defenses to its obligations under the Series C Documents against those rights and obligations of the Investors.

(p) The Company has obtained the approval of its stockholders to the extent required by applicable rules and regulations of the American Stock Exchange for the issuance of Common Stock upon conversion of the Preferred C Shares in excess of the Exchange Cap (as defined in the Certificate of Amendment).

(r) Conversion Amount of the Series C Preferred Stock. The Conversion Amount of the Series C Preferred Stock, as defined in the Certificate of Amendment governing the Series C Preferred Stock is $11,671.233 per share of Series C Preferred Stock as of February 12, 2004.

(a) Filing of Form 8-K. On or before the second business day after the Closing Date, the Company shall submit a Form 8-K to the U.S. Securities and Exchange Commission describing the terms of this Agreement.

(b) Possible Future Investment. The Company and the Investors agree to negotiate in good faith to reach an agreement for purchases from the Company by the Investors, on a pro rata basis to their investments in Preferred C Shares, of an aggregate of $2,500,000 of equity securities of the Company, with a view towards achieving $1,250,000 of such investment within seven (7) days of the date hereof and the remainder upon receipt of approval by the Company’s stockholders or satisfaction of any other requirements imposed by the AMEX.

(a) The representations and warranties of the Investors shall be true and correct as of the date when made and as of the Closing as though made at that time and the Investors shall have performed, satisfied and complied with the covenants, agreements and conditions required by this Agreement to be performed, satisfied or complied with by the Investors at or prior to the Closing.
