American Stock Transfer FBO Xoma Corporation, with reference to the rights holders name
Any wire transfer should clearly indicate the identity of the subscriber who is paying the Subscription Price by wire transfer.
(b) personal check, U.S. postal money order or bank draft payable to AST (acting as subscription agent for XOMA Corporation).
Payments will be deemed to have been received upon (i) clearance of any uncertified check, (ii) receipt by the Subscription Agent of any bank draft
drawn upon a U.S. bank or (iii) receipt of wire transfers of immediately available funds in the Subscription Account designated above.
If paying by
uncertified personal check, please note that the funds paid thereby may take five or more business days to clear. Accordingly, holders of Rights who wish to pay the aggregate Subscription Price by means of uncertified personal check are urged to
make payment sufficiently in advance of the Expiration Time to ensure that such payment is received and clears by such date and are urged to consider payment by means of wire transfer of funds.
All Rights Certificates, payments of the subscription price (other than wire transfers) and nominee holder certifications, to the extent applicable to your
exercise of Rights, must be delivered by mail, hand or overnight courier to the Subscription Agent as follows:
Transfer & Trust Company, LLC
6201 15th Avenue
Brooklyn, NY 11219
877-248-6417 or 718-921-8317
Delivery to an address other than the address above does not constitute valid delivery.
If you have any questions, require assistance regarding the method of exercising Rights or require additional copies of relevant documents, please contact the
Information Agent, D.F. King & Co., Inc., at 48 Wall Street, New York, NY 10005, or by phone at 212-269-5550 or 866-721-1324.
By making arrangements with your bank or broker for the delivery of funds on your behalf, you may
also request such bank or broker to exercise the Rights Certificate on your behalf.
Brokers, custodian banks and other nominee holders who exercise the
Subscription Right on behalf of beneficial owners of Rights will be required to certify to the Subscription Agent and the Company as to the aggregate number of Rights that have been exercised pursuant to the Subscription Right by each beneficial
owner of Rights (including such nominee itself) on whose behalf such nominee holder is acting.
If you do not indicate the number of Rights being
exercised, or do not forward full payment of the Subscription Price for all of the Rights you purport to exercise, then you will be deemed to have exercised your Rights with respect to the maximum number of whole Rights that may be exercised with
the aggregate amount of Subscription Price you delivered to the Subscription Agent.
If the Company does not apply your full Subscription Price payment to
your purchase of Rights Offering Shares, the excess subscription payment received by the Subscription Agent will be returned to you, without interest or penalty, as soon as practicable.
2. Issuance of Rights Offering Shares.
Offering Shares that you purchase in the Rights Offering will be issued in book-entry, or uncertificated, form. When issued, the Rights Offering Shares will be registered in the name of the Recordholder. As soon as practicable after the expiration
of the Rights Offering (including after all prorations and adjustments contemplated by the terms of the Rights Offering, as described in the Prospectus, have been effected), the Subscription Agent will arrange for the issuance of the Rights Offering
Shares allotted to the holders exercising their Subscription Rights in the Rights Offering.
As soon as practicable after the Expiration Time and after
all prorations and adjustments contemplated by the terms of the Rights Offering, as described in the Prospectus, have been effected, any excess subscription payment received by the Subscription Agent will be returned, without interest or penalty.
