the Exchange Act of 1934, as amended (the "Act"), the beneficial owner of any
securities covered by this Schedule 13D.

ordinary course of business, to have an influence or control over the
management and policies of the Issuer.  Consequently, the date of event that

The securities covered by this Schedule 13D were acquired by or granted to
Franklin A. Burke on his own behalf and on behalf of his spouse, the
guardianship, the trusts, the Fund, the investment advisers and their
clients, respectively, as described above, for passive investment purposes of
investment in the ordinary course of business and not with the purpose nor
with the effect of changing or influencing the control of the Issuer.
Franklin A. Burke's ownership of the Issuer's shares is largely due to the
forced conversion of the Issuer's bonds into stocks.

The Reporting Person may in the future, respectively, on his own behalf
and/or on behalf of his spouse, the guardianship, the trusts, the Fund, the
investment advisers and/or their clients, for passive investment purposes, as
described above, acquire beneficial ownership of shares of Common Stock of
the Issuer, in the open market or otherwise, and may also, depending on then
current circumstances, dispose of all or a portion of the Common Stock
beneficially owned by the Reporting Person in multiple transactions.  Other
than as described above, the Reporting Person does not have any present
plans or proposals which relate to or that would result in any of the actions
or transactions described in paragraphs (a) through (j) of Item 4 of the
instructions to Schedule 13D.
