        <footnote id="F1">These shares were acquired from a Section 423 Employee Stock Purchase Plan.  The transaction for acquisition of the shares was filed as a reportable transaction with an incorrect code.  However, the acquisition is a NON-Reportable transaction and the code indicated on the original filing was incorrect.  The subsequent disposition of these holdings were reported correctly on a Form 4 filed on 10/21/03 and is just being resubmitted to correct the reporting of the acquisition.</footnote>
