(b) Lender may convert the above specified amount of this Note at the then applicable Conversion Price by the surrender of this Note (properly endorsed) at the principal office of the Borrower, or at such other agency or office of the Borrower in the United States of America as the Borrower may designate by notice in writing to the Lender at the address of Lender appearing herein.

(h) In the event that the shareholders of Borrower adopt and approve a plan of merger pursuant to which the Borrower merges with and into a wholly owned Delaware subsidiary ("Newco"), and pursuant to such plan of merger, the holders of the common stock of the Borrower are to receive shares of common stock of Newco, then effective immediately prior, and subject to, the consummation of such merger, this Note shall automatically convert in full (including all 3 outstanding principal and interest thereon) into such number shares of Borrower's common stock which would entitle the Lender to receive in such merger such number of shares of Newco's common stock equal to one percent of the total outstanding shares of Newco's common stock immediately following the merger for each $30,000 of outstanding principal under this Note at the time of such merger, up to a total often percent. Upon such automatic conversion, this Note shall terminate and be cancelled in full, without any further action by Lender or Borrower, and all of Borrower's obligations and liabilities hereunder shall terminate in full upon such automatic conversion. (i) The issuance of certificates for shares of the Common Stock or other securities on conversion of this Note shall be made without charge to the Lender for any documentary stamp or similar taxes that may be payable in respect of the issue or delivery of such certificate, provided that the Borrower shall not be required to pay any tax that may be payable in respect of any transfer involved in the issuance and delivery of any such certificate upon conversion in a name other than that of the Lender and the Borrower shall not be required to issue or deliver such certificates unless or until the person or persons requesting the issuance thereof shall have paid to the Borrower or its designee the amount of such tax or shall have established to the satisfaction of the Borrower that such tax has been paid. (j) Upon conversion hereunder, the Borrower may issue stock certificates representing fractions of shares of the Common Stock. (k) Nothing herein shall limit any right granted to Lender by any other instrument or document or by law or equity. 3. Prepayment.
