        <footnote id="F1">On 11/07/2007 the reporting person mistakenly filed a Form 4A indicating the acquisition of 2262 shares of Millipore Common Stock upon the exercise of a nonqualified stock option and payment of the exercise price by delivery of 890 shares of previously owned Millipore Common Stock.  That transaction did not in fact occur.  As of 11/07/2007 the reporting person beneficially owned 1419 shares of Millipore Common Stock.</footnote>
