                  This Amendment No. 1 to Schedule 13D (this "Amendment") is

Persons." This Amendment is also being filed by Mr. Saul E. Diamond and Mr. Guy
W. Adams. The Greenlight Persons, together with Messrs. Diamond and Adams, are

meaning of Section 13(d)(3) of the Securities Exchange Act of 1934 (the
"Exchange Act"). Notwithstanding the foregoing, the filing of this Amendment
should not be deemed an admission that the Reporting Persons comprise a group
within the meaning of Section 13(d)(3) of the Exchange Act. Information with
respect to each person filing this statement is given solely by such person and
no person has responsibility for the accuracy or completeness of the information
supplied by another person. This Amendment modifies the original 13D filed by
the Reporting Persons on June 23, 2003 (the "Original 13D")

                  This Amendment relates to common shares of beneficial interest
of the Issuer, par value $1.00 per share ("Common Shares"), owned by (i)
Greenlight Capital, L.P. ("Greenlight Fund") and (ii) Greenlight Capital
Qualified, L.P. ("Greenlight Qualified"), of which Greenlight LLC is the general
partner, and (iii) Greenlight Capital Offshore, Ltd. ("Greenlight Offshore", and
together with Greenlight Fund and Greenlight Qualified, the "Greenlight Funds")
for which Greenlight Inc. acts as the investment advisor. It also relates to
Common Shares underlying certain options with respect to which Messrs. Diamond
and Adams may be deemed beneficial owners.

ITEM 4.           PURPOSE OF THE TRANSACTION

Item 4 of the Original 13D is hereby amended by adding the following:

                  On July 2, 2003, Greenlight filed a definitive proxy statement
on Schedule 14A (the "Definitive Proxy") with the Securities and Exchange
Commission relating to its proxy solicitation.
