The Contingent Payment shall be capped at the amount by which the net proceeds from new equity financing exceeds $3,000,000. (d) If the Investor has not been paid Royalty Payments equal to the Principal Investment Amount by December 31, 2008, the Investor shall have the option, for a 30 day period commencing on January 1, 2009 and ending on January 31, 2009, to convert the funds received by the Company pursuant to this Agreement into: (i) a royalty participation from any other product that the Company may have developed and entered into a license agreement for (an "Alternative Royalty Stream").
