    <footnotes>
        <footnote id="F1">In November of 2002, Applied DNA Sciences, Inc. (the &quot;Company&quot;) created a compensation plan for founders, employees and consultants which was filed the Securities and Exchange Commission on a Form S-8 (the &quot;Plan&quot;) which was later amended in January of 2003. The Plan provides an alternative method of compensating individuals whose services are important to the ongoing development of the Company.  Shares are issued to eligible recipients in lieu of cash compensation in accordance with employment o
r consulting agreements entered into between them and the Company.  Such recipients, including the reporting person, signed leak out agreements with the Company, limiting the number of shares they are permitted to sell in a thirty day period.  Compensation shares such as these are exempt from the short swing rule by reason of Rule 16(b)3.</footnote>
        <footnote id="F2">A Form 144 was properly filed prior to making this sale.</footnote>
