D. Borrower now desires to draw-down an additional $250,000 under the Loan (the “Additional Draw-Down”), and combine the Existing Loan Balance and the Additional Draw-Down (collectively, the “Total Outstanding Loan Balance”) into one Note having a principal balance of $450,000, with an extension of the maturity date of the Loan to August 19, 2008 (the “Revised Note”).
 
E. As an inducement to Lender to lend the Additional Draw-Down and to accept the Revised Note, Borrower agrees (i) that the Revised Note shall bear interest at the rate of 8.68% per annum, and (ii) to issue to Lender a warrant to purchase shares of Common Stock as more particularly set forth herein.
