“This is to certify that, in exchange for the Warrantholder’s commitment to purchase one or more of the Company’s Senior Secured Promissory Notes, due March 1, 2010, in the original aggregate principal amount of $5,300,000, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, and subject to the

1.2 Section 3(a) of the Warrant is hereby amended in its entirety to read as follows:

“(a) If the Company at any time or from time to time after the date of this Warrant effects a subdivision of shares of its Common Stock, the number of shares of Common Stock issuable to Warrantholder immediately before that subdivision shall be proportionately increased, and conversely, if the Company at any time or from time to time after the date of this Warrant combines shares of Common Stock into a smaller number of shares, the number of shares of Common Stock issuable to Warrantholder immediately before the combination shall be proportionately decreased. Any adjustment under this clause (a) shall become effective at the close of business on the date the subdivision or combination becomes effective. The number of shares of Common Stock issuable to Warrantholder, as so adjusted, shall be readjusted in the same manner upon the happening of any successive event or events described in this Section 3(a). Notwithstanding the fact that the Company may divide its Common Stock into a greater number of shares or combine its Common Stock into a small number of shares, in no event shall the Exercise Price be increased as a result of such action with respect to the Common Stock of the Company.”
