Explanatory Note
Pursuant to a Registration Statement on Form S-3 (Registration No.
333-101035) ("Registration Statement"), XOMA Ltd., a Bermuda company (the
"Registrant"), registered 5,000,000 of its common shares. The Registration
Statement was declared effective on December 13, 2002.
The purpose of this Post-Effective Amendment to the Registration Statement
is to deregister and remove from registration the 5,000,000 common shares
previously registered on the Registration Statement. No securities have been
sold in connection with the Registration Statement. This action is caused by the
Registrant's renegotiation of certain material provisions of the agreements by
which investors have obligated themselves to purchase common shares of the
Registrant and for which the Registration Statement was filed. Contemporaneously
with the filing of this letter, the Registrant has filed a new registration
statement on Form S-3 which reflects the new terms of the agreements.

authorized, in the City of Berkeley, State of California, on May 23, 2003.
