Item 1.01. Entry into a Material Definitive Agreement

     On February 7, 2005, XOMA Ltd., (the "Company"), closed its previously
disclosed private placement of the Company's 6.50% Convertible Senior Notes due
2012 (the "Notes") in an aggregate principal amount of $60,000,000 to qualified
institutional buyers pursuant to exemptions from the registration requirements
of the Securities Act of 1933 (the "Act").

     In connection with the closing, on February 7, 2005, the Company entered
into an indenture (the "Indenture") with Wells Fargo Bank, National Association,
as trustee, governing the Notes. The Notes bear interest at a rate of 6.50% per
annum and are convertible into the Company's common shares at an initial
conversion rate of 533.4756 common shares per $1,000 principal amount of Notes,
subject to adjustment (equivalent to a conversion price of approximately $1.87
per share). The Notes will mature on February 1, 2012. The Company may redeem
the Notes after February 6, 2008 if the Company's common shares trade at 150% of
the conversion price for a specified period. Upon the occurrence of certain
designated events prior to the maturity of the Notes, subject to specified
exceptions, investors will have the right to require the Company to redeem the
Notes. In addition, upon the occurrence of an "Event of Default", as defined in
the Indenture, the holders of Notes or the trustee shall have the right to cause
the Notes to become due and payable in full. Interest on the Notes will be
payable on February 1 and August 1 of each year, beginning on August 1, 2005.

     The initial purchasers of the Notes and their direct and indirect
transferees will be entitled to the benefits of a Registration Rights Agreement,
dated as of February 7, 2005 (the "Registration Rights Agreement"), between the
Company and the initial purchasers party thereto. Pursuant to the Registration
Rights Agreement, the Company has agreed to register the Securities under the
Act within a specified time or pay additional amounts to the holders of notes.
