                 report shall not be construed as an admission
                 of beneficial ownership for the purposes of
                 Section 13 or any other purpose.

            stock for which the Reporting Person serves as sole
            or co-fiduciary with respect to trust and other
            accounts. The Reporting Person is not aware of any
