2011 and declared effective on June 6, 2011 (the&nbsp;&#147;2011 Registration Statement&#148;). The 2012 Registration Statement registered the offer and sale of an indeterminate number of shares of common stock and preferred stock, an indeterminate
principal amount of debt securities, and an indeterminate number of warrants to purchase common stock, preferred stock or debt securities, having an aggregate initial offering price of $100,000,000, a portion of which remain unsold as the date of

number of warrants to purchase common stock, preferred stock or debt securities, having an aggregate initial offering price of $100,000,000. The Registrant has determined to include in this Registration Statement unsold securities under the 2012
Registration Statement with an aggregate offering price of $28,375,004 (the &#147;Unsold Securities&#148;) and the Warrant Shares. Pursuant to Rule&nbsp;415(a)(6) under the Securities Act, the filing fee of $3,297.17 relating to the Unsold
Securities under the 2012 Registration Statement will continue to be applied to the Unsold Securities registered pursuant to this Registration Statement. The Registrant is also registering new securities on this registration statement with an
aggregate initial offering price of $271,624,996 (the &#147;New Securities&#148;), which aggregate offering price is not specified as to each class of security (see footnote (3)). To the extent that, after the filing date hereof and prior to the
effectiveness of this Registration Statement, the Registrant sells any Unsold Securities pursuant to the 2012 Registration Statement, the Registrant will identify in a pre-effective amendment to this Registration Statement the updated amount of
Unsold Securities from the 2012 Registration Statement to be included in this Registration Statement pursuant to Rule&nbsp;415(a)(6) and the updated amount of New Securities to be registered on this Registration Statement. Pursuant to

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">XOMA Corporation (&#147;XOMA&#148;), a Delaware corporation, discovers and develops innovative antibody-based therapeutics. Several of our
antibodies have unique properties due to their interaction at allosteric sites on specific protein rather than the orthosteric, or active sites. The compounds are designed to either enhance or diminish the protein&#146;s activity as desired. We
believe allosteric-modulating antibodies may be more selective or offer a safety advantage in certain disease indications when compared to more traditional modes of action. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our lead drug candidate, gevokizumab, is a proprietary potent, humanized allosteric-modulating monoclonal antibody that binds to the
inflammatory cytokine interleukin-1 beta (&#147;IL-1 beta&#148;). We believe that by targeting IL-1 beta, gevokizumab has the potential to address the underlying inflammatory causes of a wide range of diseases that have been identified as having
unmet medical needs. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Together with our development partner, Les Laboratoires Servier (&#147;Servier&#148;), an independent French
pharmaceutical research company, we have initiated four pivotal clinical trials evaluating gevokizumab for the treatment of non-infectious intermediate, posterior or pan-uveitis (&#147;NIU&#148;) and Beh&ccedil;et&#146;s disease uveitis. We are
responsible for all of the clinical study sites in the United States, and Servier is responsible for all of the clinical study sites outside of the United States. These studies are known as the EYEGUARD&#153; program, which includes EYEGUARD-A
(patients with active NIU), EYEGUARD-B (patients with Beh&ccedil;et&#146;s disease uveitis outside of the United States), EYEGUARD-C (patients with a history of NIU currently controlled with systemic treatment), and EYEGUARD-US (patients with
Beh&ccedil;et&#146;s disease uveitis being conducted at study centers in the United States). </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our strategy is to pursue
Beh&ccedil;et&#146;s disease uveitis as our first indication for gevokizumab in the United States. Upon the successful completion of SERVIER&#146;s EYEGUARD-B study, we intend to meet with the U.S. Food and Drug Administration (&#147;FDA&#148;) to
review the Phase 3 EYEGUARD-B data together with the data from the two Beh&ccedil;et&#146;s disease uveitis Phase 2 studies conducted independently by XOMA and Servier. We believe the seriousness of this disease and the small patient population
warrant consideration for approval based upon positive data from a single pivotal study. There is significant precedence for regulatory approval based upon a single study for indications of similar seriousness in patient populations. Should
EYEGUARD-B successfully demonstrate patients with Beh&ccedil;et&#146;s disease uveitis receiving gevokizumab took longer to exacerbate than the placebo-treated patients during the tapering of administered steroids, we believe we will be in position
to begin the Biologics License Application (&#147;BLA&#148;) submission process. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In addition to the EYEGUARD studies, we are evaluating
gevokizumab in pyoderma gangrenosum (&#147;PG&#148;), a rare ulcerative skin disease that is a specific indication under the umbrella of diseases known as neutrophilic dermatosis. Patients experience painful expanding skin ulcers that have a
significant impact on their quality of life. The U.S. Department of Health and Human Services&#146; National Institutes of Health&#146;s Office of Rare Disease Research lists PG occurring in about one per 100,000 people. Claims data compiled

 <P STYLE="margin-top:0pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">
over the past three years indicate the number of diagnosed PG patients in the U.S. ranges between 11,000 and 14,000 annually. Based upon what we believe are compelling data from our pilot study
in patients with PG, we initiated a Phase 3 clinical program in October 2014. The PG Phase 3 program includes two double-blind, placebo-controlled clinical studies, each of which is designed to enroll 58 patients with active PG to receive
gevokizumab 60 mg or placebo dosed subcutaneously once monthly, in addition to their current treatment regimen of low-dose corticosteroids and/or immunosuppressants. The primary endpoint is the complete closure of the PG target ulcer determined at
Day 126 and confirmation of complete closure a minimum of two weeks later on or after Day 140. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We and Servier also have an active
gevokizumab Proof-of-Concept (&#147;POC&#148;) development program to identify other illnesses for late-stage development. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Gevokizumab
has been generally well tolerated across all of our clinical studies. The most common adverse events were headache, pain, arthralgia, urinary tract infections, upper respiratory tract infections and pneumonia, and they were comparable between
gevokizumab and placebo. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our proprietary pipeline includes classes of allosteric modulating antibodies that activate, sensitize or
deactivate the insulin receptor in vivo, which we have named XOMA Metabolism or XMet. Insulin is the major hormone for lowering blood glucose levels. Abnormal increases in insulin secretion can lead to profound hypoglycemia (low blood sugar), a
state that may result in significant morbidities including cerebral damage and epilepsy. In some instances, profound hypoglycemia can result in fatality. There are three programs in the XMet portfolio, XOMA 358, which is designed to deactivate the
insulin receptor, XMetA, which is designed to activate the insulin receptor, and XMetS, which is designed to sensitize the insulin receptor when in an insulin resistant state. These programs are highly novel as the antibodies bind to different sites
on the insulin receptor than currently marketed drugs. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">XOMA 358 is a fully human monoclonal allosteric modulating antibody that binds to
insulin receptors and attenuates insulin action. It is designed to negatively modulate the insulin receptor and its downstream signaling capabilities. We launched clinical development activities for XOMA 358 in October 2014, with the first patient
dosed in our Phase 1 safety and tolerability study. We intend to investigate this compound as a novel treatment for non-drug-induced, endogenous hyperinsulinemic hypoglycemia (low blood glucose caused by excessive insulin produced by the body). A
therapy that safely and effectively mitigates insulin-induced hypoglycemia has the potential to address a significant unmet therapeutic need for certain rare medical conditions associated with hyperinsulinism. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We intend to retain full ownership of the XOMA 358, as it aligns with our focus to develop products for diseases with significant unmet
medical need and treated by the specialist prescriber. We intend to license XMetA and XMetS to a pharmaceutical company with expertise in developing and commercializing compounds for Types 1 and 2 diabetes. This portfolio of antibodies represents
potential new therapeutic approaches to the treatment of diabetes and several rare diseases that have insulin involvement. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Risks Associated with our

the risks and uncertainties described under the heading &#147;Risk Factors&#148; contained in the applicable prospectus supplement and any related free writing prospectus, and discussed under the section entitled &#147;Risk Factors&#148; contained
in our most recent Annual Report on Form 10-K and in our most recent Quarterly Report on Form 10-Q, as well as any amendments thereto reflected in subsequent filings with the SEC, which are incorporated by reference into this prospectus in their
entirety, together with other information in this prospectus, the documents incorporated by reference and any free writing prospectus that we may authorize for use in connection with this offering. The risks described in these documents are not the
only ones we face, but those that we consider to be material. There may be other unknown or unpredictable economic, business, competitive, regulatory or other factors that could have material adverse effects on our future results. Past financial
performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. If any of these risks actually occurs, our business, financial condition, results of
operations or cash flow could be seriously harmed. This could cause the trading price of our common stock to decline, resulting in a loss of all or part of your investment. Please also read carefully the section below entitled &#147;Forward-Looking
Statements.&#148; </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman" ALIGN="center"><B><A NAME="tx865655_5"></A>Forward-Looking Statements </B></P>

writing prospectus including the documents we incorporate by reference therein may contain, forward-looking statements, including statements related to the anticipated size of clinical trials, the anticipated timing of initiation of clinical trials,
the expected availability of clinical trial results, the sufficiency of our cash resources, the estimated costs of clinical trials and the amounts of certain revenues and certain costs in comparison to prior years, or that otherwise relate to future
periods, are forward-looking statements within the meaning of Section&nbsp;27A of the Securities Act and Section&nbsp;21E of the Securities Exchange Act of 1934, as amended (the &#147;Exchange Act&#148;). The words &#147;believe,&#148;

These statements are based on assumptions that may not prove accurate. Actual results could differ materially from those anticipated due to certain risks inherent in the biotechnology industry and for companies engaged in the development of new
products in a regulated market. Among other things: our product candidates are still being developed, and we will require substantial funds to continue development which may not be available; we have sustained losses in the past and we expect to
sustain losses in the future; we are substantially dependent on Servier for the development and commercialization of gevokizumab and for other aspects of our business; we have received negative results from certain of our clinical trials, and the
pace of certain ongoing trials has not always been what was initially anticipated, and we face uncertain results of other clinical trials of our product candidates; if our therapeutic product candidates do not receive regulatory approval, neither
our third-party collaborators, our contract manufacturers nor we will be able to manufacture and market them; we may not obtain orphan drug exclusivity or we may not receive the full benefit of orphan drug exclusivity even if we obtain such
exclusivity; even once approved, a product may be subject to additional testing or significant marketing restrictions, its approval may be withdrawn or it may be voluntarily taken off the market; we may not be successful in commercializing our
products, which could also affect our development efforts; we are subject to various state and federal healthcare related laws and regulations that may impact the commercialization of ACEON or our product candidates and could subject us to
significant fines and penalties; and certain of our technologies are in-licensed from third parties, so our capabilities using them are restricted and subject to additional risks. These and other risks, including those related to current economic
and financial market </P>

stockholders) will generally vote together as a single class on all matters presented to the stockholders for their vote or approval, including the election of directors. Any matter brought before the stockholders for a vote, other than the election
of directors, will generally be decided by a majority of the votes cast on the matter, unless the matter is one in which an express provision of the Delaware General Corporation Law, or the DGCL, the certificate of incorporation, the bylaws, the

<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We may issue debt securities from time to time, in one or more series, as either senior or subordinated debt or as senior or subordinated
convertible debt. While the terms we have summarized below will apply generally to any debt securities that we may offer under this prospectus, we will describe the particular terms of any debt securities that we may offer in more detail in the
applicable prospectus supplement. The terms of any debt securities offered under a prospectus supplement may differ from the terms described below. Unless the context requires otherwise, whenever we refer to the indenture, we also are referring to
any supplemental indentures that specify the terms of a particular series of debt securities. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We will issue the debt securities under the
indenture that we will enter into with the trustee named in the indenture. The indenture will be qualified under the Trust Indenture Act of 1939, as amended, or the Trust Indenture Act. We have filed the form of indenture as an exhibit to the
registration statement of which this prospectus is a part, and supplemental indentures and forms of debt securities containing the terms of the debt securities being offered will be filed as exhibits to the registration statement of which this
prospectus is a part or will be incorporated by reference from reports that we file with the SEC. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The following summary of material
provisions of the debt securities and the indenture is subject to, and qualified in its entirety by reference to, all of the provisions of the indenture applicable to a particular series of debt securities. We urge you to read the applicable
prospectus supplements and any related free writing prospectuses related to the debt securities that we may offer under this prospectus, as well as the complete indenture that contains the terms of the debt securities. </P>

amount of debt securities that we may issue. It provides that we may issue debt securities up to the principal amount that we may authorize and may be in any currency or currency unit that we may designate. Except for the limitations on
consolidation, merger and sale of all or substantially all of our assets contained in the indenture, the terms of the indenture do not contain any covenants or other provisions designed to give holders of any debt securities protection against
changes in our operations, financial condition or transactions involving us. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We may issue the debt securities issued under the indenture
as &#147;discount securities,&#148; which means they may be sold at a discount below their stated principal amount. These debt securities, as well as other debt securities that are not issued at a discount, may be issued with &#147;original issue
discount,&#148; or OID, for U.S. federal income tax purposes because of interest payment and other characteristics or terms of the debt securities. Material U.S. federal income tax considerations applicable to debt securities issued with OID will be
described in more detail in any applicable prospectus supplement. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We will describe in the applicable prospectus supplement the terms of

<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We can issue securities in registered form or in the form of one or more global securities. We describe global securities in greater detail
below. We refer to those persons who have securities registered in their own names on the books that we or any applicable trustee, depositary or warrant agent maintain for this purpose as the &#147;holders&#148; of those securities. These persons
are the legal holders of the securities. We refer to those persons who, indirectly through others, own beneficial interests in securities that are not registered in their own names, as &#147;indirect holders&#148; of those securities. As we discuss
below, indirect holders are not legal holders, and investors in securities issued in book-entry form or in street name will be indirect holders. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Book-Entry Holders </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We may issue
securities in book-entry form only, as we will specify in the applicable prospectus supplement. This means securities may be represented by one or more global securities registered in the name of a financial institution that holds them as depositary
on behalf of other financial institutions that participate in the depositary&#146;s book-entry system. These participating institutions, which are referred to as participants, in turn, hold beneficial interests in the securities on behalf of
themselves or their customers. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Only the person in whose name a security is registered is recognized as the holder of that security.
Securities issued in global form will be registered in the name of the depositary or its participants. Consequently, for securities issued in global form, we will recognize only the depositary as the holder of the securities, and we will make all
payments on the securities to the depositary. The depositary passes along the payments it receives to its participants, which in turn pass the payments along to their customers who are the beneficial owners. The depositary and its participants do so
under agreements they have made with one another or with their customers; they are not obligated to do so under the terms of the securities. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">As a result, investors in a book-entry security will not own securities directly. Instead, they will own beneficial interests in a global
security, through a bank, broker or other financial institution that participates in the depositary&#146;s book-entry system or holds an interest through a participant. As long as the securities are issued in global form, investors will be indirect
holders, and not holders, of the securities. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Street Name Holders </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We may terminate a global security or issue securities in non-global form. In these cases, investors may choose to hold their securities in
their own names or in &#147;street name.&#148; Securities held by an investor in street name would be registered in the name of a bank, broker or other financial institution that the investor chooses, and the investor would hold only a beneficial
interest in those securities through an account he or she maintains at that institution. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">For securities held in street name, we will
recognize only the intermediary banks, brokers and other financial institutions in whose names the securities are registered as the holders of those securities, and we will make all payments on those securities to them. These institutions pass along
the payments they receive to their customers who are the beneficial owners, but only because they agree to do so in their customer agreements or because they are legally required to do so. Investors who hold securities in street name will be
indirect holders, not holders, of those securities. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Legal Holders </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our obligations, as well as the obligations of any applicable trustee and of any third parties employed by us or a trustee, run only to the
legal holders of the securities. We do not have obligations to investors who hold beneficial interests in global securities, in street name or by any other indirect means. This will be the case whether an investor chooses to be an indirect holder of
a security or has no choice because we are issuing the securities only in global form. </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">For example, once we make a payment or give a notice to the holder, we have no further
responsibility for the payment or notice even if that holder is required, under agreements with depositary participants or customers or by law, to pass it along to the indirect holders but does not do so. Similarly, we may want to obtain the
approval of the holders to amend an indenture, to relieve us of the consequences of a default or of our obligation to comply with a particular provision of the indenture or for other purposes. In such an event, we would seek approval only from the

security that represents one or any other number of individual securities held by a depositary. Generally, all securities represented by the same global securities will have the same terms. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Each security issued in book-entry form will be represented by a global security that we deposit with and register in the name of a financial
institution or its nominee that we select. The financial institution that we select for this purpose is called the depositary. Unless we specify otherwise in the applicable prospectus supplement, DTC will be the depositary for all securities issued
in book-entry form. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">A global security may not be transferred to or registered in the name of anyone other than the depositary, its
nominee or a successor depositary, unless special termination situations arise. We describe those situations below under &#147;Special Situations When a Global Security Will Be Terminated.&#148; As a result of these arrangements, the depositary, or
its nominee, will be the sole registered owner and holder of all securities represented by a global security, and investors will be permitted to own only beneficial interests in a global security. Beneficial interests must be held by means of an
account with a broker, bank or other financial institution that in turn has an account with the depositary or with another institution that does. Thus, an investor whose security is represented by a global security will not be a holder of the
security, but only an indirect holder of a beneficial interest in the global security. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">If the prospectus supplement for a particular
security indicates that the security will be issued in global form only, then the security will be represented by a global security at all times unless and until the global security is terminated. If termination occurs, we may issue the securities
through another book-entry clearing system or decide that the securities may no longer be held through any book-entry clearing system. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Special
Considerations for Global Securities </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The rights of an indirect holder relating to a global security will be governed by the account
rules of the investor&#146;s financial institution and of the depositary, as well as general laws relating to securities transfers. We do not recognize an indirect holder as a holder of securities and instead deal only with the depositary that holds
the global security. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">If securities are issued only in the form of a global security, an investor should be aware of the following: </P>

any agent involved in the offer or sale of the securities and any commissions we pay to them. Generally, any agent will be acting on a best efforts basis for the period of its appointment. We may authorize underwriters, dealers or agents to solicit
offers by certain purchasers to purchase the securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. The
contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth any commissions we pay for solicitation of these contracts. </P>

Securities Act, or to contribution with respect to payments which the agents, dealers or underwriters may be required to make in respect thereof. Agents, dealers and underwriters may be customers of, engage in transactions with, or perform services
for us in the ordinary course of business. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">All securities we may offer, other than common stock, will be new issues of securities with no
established trading market. Any underwriters may make a market in these securities, but will not be obligated to do so and may discontinue any market making at any time without notice. We cannot guarantee the liquidity of the trading markets for any
securities. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Any underwriter may engage in overallotment, stabilizing transactions, short covering transactions and penalty bids in
accordance with Regulation M under the Securities Exchange Act of 1934, as amended. Overallotment involves sales in excess of the offering size, which create a short position. This short sales position may involve either &#147;covered&#148; short
sales or &#147;naked&#148; short sales. Covered short sales are short sales made in an amount not greater than the underwriters&#146; over-allotment option to purchase additional securities in this offering described above. The underwriters may
close out any covered short position either by exercising their over-allotment option or by purchasing securities in the open market. To determine how they will close the covered short position, the underwriters will consider, among other things,
the price of securities available for purchase in the open market, as compared to the price at which they may purchase securities through the over-allotment option. Naked short sales are short sales in excess of the over-allotment option. The
underwriters must close out any naked short position by purchasing securities in the open market. A naked short position is more likely to be created if the underwriters are concerned that, in the open market after pricing, there may be downward
pressure on the price of the securities that could adversely affect investors who purchase securities in this offering. Stabilizing transactions permit bids to purchase the underlying security for the purpose of fixing the price of the security so
long as the stabilizing bids do not exceed a specified maximum. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a covering transaction to cover
short positions. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Any underwriters who are qualified market makers on the NASDAQ Global Market may engage in passive market making
transactions in our common stock, preferred stock, warrants and debt securities, as applicable, on the NASDAQ Global Market in accordance with Rule 103 of Regulation M, during the business day prior to the pricing of the offering, before the
commencement of offers or sales of the securities. Passive market makers must comply with applicable volume and price limitations and must be identified as passive market makers. In general, a passive market maker must display its bid at a price not
in excess of the highest independent bid for such security; if all independent bids are lowered below the passive market maker&#146;s bid, however, the passive market maker&#146;s bid must then be lowered when certain purchase limits are exceeded.

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">XOMA Corporation (&#147;XOMA&#148;), a Delaware corporation, discovers and develops innovative antibody-based therapeutics. Several of our
antibodies have unique properties due to their interaction at allosteric sites on specific protein rather than the orthosteric, or active sites. The compounds are designed to either enhance or diminish the protein&#146;s activity as desired. We
believe allosteric-modulating antibodies may be more selective or offer a safety advantage in certain disease indications when compared to more traditional modes of action. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our lead drug candidate, gevokizumab, is a proprietary potent, humanized allosteric-modulating monoclonal antibody that binds to the
inflammatory cytokine interleukin-1 beta (&#147;IL-1 beta&#148;). We believe that by targeting IL-1 beta, gevokizumab has the potential to address the underlying inflammatory causes of a wide range of diseases that have been identified as having
unmet medical needs. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Together with our development partner, Les Laboratoires Servier (&#147;Servier&#148;), an independent French
pharmaceutical research company, we have initiated four pivotal clinical trials evaluating gevokizumab for the treatment of non-infectious intermediate, posterior or pan-uveitis (&#147;NIU&#148;) and Beh&ccedil;et&#146;s disease uveitis. We are
responsible for all of the clinical study sites in the United States, and Servier is responsible for all of the clinical study sites outside of the United States. These studies are known as the EYEGUARD&#153; program, which includes EYEGUARD-A
(patients with active NIU), EYEGUARD-B (patients with Beh&ccedil;et&#146;s disease uveitis outside of the United States), EYEGUARD-C (patients with a history of NIU currently controlled with systemic treatment), and EYEGUARD-US (patients with
Beh&ccedil;et&#146;s disease uveitis being conducted at study centers in the United States). </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our strategy is to pursue
Beh&ccedil;et&#146;s disease uveitis as our first indication for gevokizumab in the United States. Upon the successful completion of SERVIER&#146;s EYEGUARD-B study, we intend to meet with the U.S. Food and Drug Administration (&#147;FDA&#148;) to
review the Phase 3 EYEGUARD-B data together with the data from the two Beh&ccedil;et&#146;s disease uveitis Phase 2 studies conducted independently by XOMA and Servier. We believe the seriousness of this disease and the small patient population
warrant consideration for approval based upon positive data from a single pivotal study. There is significant precedence for regulatory approval based upon a single study for indications of similar seriousness in patient populations. Should
EYEGUARD-B successfully demonstrate patients with Beh&ccedil;et&#146;s disease uveitis receiving gevokizumab took longer to exacerbate than the placebo-treated patients during the tapering of administered steroids, we believe we will be in position
to begin the Biologics License Application (&#147;BLA&#148;) submission process. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In addition to the EYEGUARD studies, we are evaluating
gevokizumab in pyoderma gangrenosum (&#147;PG&#148;), a rare ulcerative skin disease that is a specific indication under the umbrella of diseases known as neutrophilic dermatosis. Patients experience painful expanding skin ulcers that have a
significant impact on their quality of life. The U.S. Department of Health and Human Services&#146; National Institutes of Health&#146;s Office of Rare Disease Research lists PG occurring in about one per 100,000 people. Claims data compiled

over the past three years indicate the number of diagnosed PG patients in the U.S. ranges between 11,000 and 14,000 annually. Based upon what we believe are compelling data from our pilot study
in patients with PG, we initiated a Phase 3 clinical program in October 2014. The PG Phase 3 program includes two double-blind, placebo-controlled clinical studies, each of which is designed to enroll 58 patients with active PG to receive
gevokizumab 60 mg or placebo dosed subcutaneously once monthly, in addition to their current treatment regimen of low-dose corticosteroids and/or immunosuppressants. The primary endpoint is the complete closure of the PG target ulcer determined at
Day 126 and confirmation of complete closure a minimum of two weeks later on or after Day 140. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We and Servier also have an active
gevokizumab Proof-of-Concept (&#147;POC&#148;) development program to identify other illnesses for late-stage development. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Gevokizumab
has been generally well tolerated across all of our clinical studies. The most common adverse events were headache, pain, arthralgia, urinary tract infections, upper respiratory tract infections and pneumonia, and they were comparable between
gevokizumab and placebo. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Our proprietary pipeline includes classes of allosteric modulating antibodies that activate, sensitize or
deactivate the insulin receptor in vivo, which we have named XOMA Metabolism or XMet. Insulin is the major hormone for lowering blood glucose levels. Abnormal increases in insulin secretion can lead to profound hypoglycemia (low blood sugar), a
state that may result in significant morbidities including cerebral damage and epilepsy. In some instances, profound hypoglycemia can result in fatality. There are three programs in the XMet portfolio, XOMA 358, which is designed to deactivate the
insulin receptor, XMetA, which is designed to activate the insulin receptor, and XMetS, which is designed to sensitize the insulin receptor when in an insulin resistant state. These programs are highly novel as the antibodies bind to different sites
on the insulin receptor than currently marketed drugs. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">XOMA 358 is a fully human monoclonal allosteric modulating antibody that binds to
insulin receptors and attenuates insulin action. It is designed to negatively modulate the insulin receptor and its downstream signaling capabilities. We launched clinical development activities for XOMA 358 in October 2014, with the first patient
dosed in our Phase 1 safety and tolerability study. We intend to investigate this compound as a novel treatment for non-drug-induced, endogenous hyperinsulinemic hypoglycemia (low blood glucose caused by excessive insulin produced by the body). A
therapy that safely and effectively mitigates insulin-induced hypoglycemia has the potential to address a significant unmet therapeutic need for certain rare medical conditions associated with hyperinsulinism. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">We intend to retain full ownership of the XOMA 358, as it aligns with our focus to develop products for diseases with significant unmet
medical need and treated by the specialist prescriber. We intend to license XMetA and XMetS to a pharmaceutical company with expertise in developing and commercializing compounds for Types 1 and 2 diabetes. This portfolio of antibodies represents
potential new therapeutic approaches to the treatment of diabetes and several rare diseases that have insulin involvement. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Risks Associated with our

&#147;intend,&#148; &#147;expect,&#148; &#147;predict,&#148; &#147;potential&#148; and similar expressions are intended to identify forward-looking statements. These statements are based on assumptions that may not prove accurate. Actual results
could differ materially from those anticipated due to certain risks inherent in the biotechnology industry and for companies engaged in the development of new products in a regulated market. Among other things: our product candidates are still being
developed, and we will require substantial funds to continue development which may not be available; we have sustained losses in the past and we expect to sustain losses in the future; we are substantially dependent on Servier for the development
and commercialization of gevokizumab and for other aspects of our business; we have received negative results from certain of our clinical trials, and the pace of certain ongoing trials has not always been what was initially anticipated, and we face
uncertain results of other clinical trials of our product candidates; if our therapeutic product candidates do not receive regulatory approval, neither our third-party collaborators, our contract manufacturers nor we will be able to manufacture and
market them; we may not obtain orphan drug exclusivity or we may not receive the full benefit of orphan drug exclusivity even if we obtain such exclusivity; even once approved, a product may be subject to additional testing or significant marketing
restrictions, its approval may be withdrawn or it may be voluntarily taken off the market; we may not be successful in commercializing our products, which could also affect our development efforts; we are subject to various state and federal
healthcare related laws and regulations that may impact the commercialization of ACEON or our product candidates and could subject us to significant fines and penalties; and certain of our technologies are in-licensed from third parties, so our
capabilities using them are restricted and subject to additional risks. These and other risks, including those related to current economic and financial market conditions, are described in more detail in &#147;Risk Factors&#148; above and the
additional risk factors contained in our most recent Annual Report on Form 10-K and Quarterly Reports on Form 10-Q. We undertake no obligation to publicly update any forward-looking statements, regardless of any new information, future events or
other occurrences. We advise you, however, to consult any additional disclosures we make in our reports to the SEC on Forms 10-K, 10-Q and 8-K. </P>

and development expenses and general and administrative expenses. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The amounts and timing of our use of the net proceeds from this

our products. As of the date of this prospectus, we cannot specify with certainty all of the particular uses for the net proceeds to us from the sale of the securities offered by us hereunder. Accordingly, our management will have broad discretion
in the timing and application of these proceeds. Pending application of the net proceeds as described above, we intend to temporarily invest the proceeds in short-term, interest-bearing instruments. </P>

share and the as adjusted net tangible book value per share after giving effect to this offering. We calculate net tangible book value per share by dividing the net tangible book value, which is tangible assets less total liabilities, by the number
of outstanding shares of our common stock. Dilution represents the difference between the portion of the amount per share paid by purchasers of shares in this offering and the as adjusted net tangible book value per share of our common stock
immediately after giving effect to this offering. Our net tangible book value as of September&nbsp;30, 2014 was approximately $(18.1)&nbsp;million, or $(0.17) per share. </P>

tangible book value as of September&nbsp;30, 2014 would have been $3.2&nbsp;million, or $0.03 per share of common stock. This represents an immediate increase in the net tangible book value of $0.20 per share to our existing stockholders and an

stockholders) will generally vote together as a single class on all matters presented to the stockholders for their vote or approval, including the election of directors. Any matter brought before the stockholders for a vote, other than the election
of directors, will generally be decided by a majority of the votes cast on the matter, unless the matter is one in which an express provision of the Delaware General Corporation Law, or the DGCL, the certificate of incorporation, the bylaws, the
rules or regulations of any stock exchange applicable to us, applicable law or pursuant to any regulation applicable to us or our securities requires a different vote, in which case the express provision will govern and control the decision of the

263,158 unregistered shares of our common stock at an exercise price equal to $1.14 per share, are immediately exercisable and will expire on December&nbsp;30, 2016. In February of 2010, we issued warrants to purchase 1,260,000 shares of our common

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman"><I>Certificate of incorporation and bylaws. </I>Our certificate of incorporation authorizes our board of directors to issue up to 1,000,000
shares of preferred stock without stockholder approval and to set the rights, preferences and other designations, including voting rights, of those shares as the board of directors may determine. In addition, our bylaws require certain procedures to
be followed and time periods to be met for any stockholder to propose matters to be considered at annual meetings of stockholders, including nominating directors for election at those meetings. Our bylaws also provide that our board of directors is
able to elect a director to fill a vacancy created by the expansion of the board of directors or due to the resignation or departure of an existing board member. Provisions of Delaware law and our certificate of incorporation and bylaws could make
the acquisition of our company through a tender offer, a proxy contest or other means more difficult and could make the removal of incumbent officers and directors more difficult. We expect these provisions to discourage coercive takeover practices
and inadequate takeover bids and to encourage persons seeking to acquire control of our company to first negotiate with our board of directors. We believe that the benefits provided by our ability to negotiate with the proponent of an unfriendly or
unsolicited proposal outweigh the disadvantages of discouraging these proposals. We believe the negotiation of an unfriendly or unsolicited proposal could result in an improvement of its terms. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Section&nbsp;102(b)(7) of the DGCL permits a corporation, in its certificate of incorporation, to limit or eliminate, subject to certain
statutory limitations, the liability of directors to the corporation or its stockholders for monetary damages for breaches of fiduciary duty, except for liability (a)&nbsp;for any breach of the director&#146;s duty of loyalty to the corporation or
its stockholders, (b)&nbsp;for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c)&nbsp;under Section&nbsp;174 of the DGCL or (d)&nbsp;for any transaction from which the director derived an
improper personal benefit. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Under Section&nbsp;145 of the DGCL, a corporation may indemnify a director, officer, employee or agent of the
corporation (or a person who is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise) against expenses (including attorneys&#146;
fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation and, with respect
to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. However, in the case of an action brought by or in the right of a corporation, the corporation may indemnify a director, officer, employee or agent of
the corporation (or a person who is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise) only against expenses (including
attorneys&#146; fees) actually and reasonably incurred by him if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, except that no indemnification may be made in respect of
any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent the appropriate court finds that, in view of all the circumstances of the case, such person is fairly and
reasonably entitled to indemnity for such expenses as the court shall deem proper. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Registrant&#146;s certificate of incorporation
provides that none of its directors shall be liable to the Registrant or its stockholders for monetary damages for breach of fiduciary duty as a director (including with regard to any actions taken or omitted as a director of the Registrant&#146;s
predecessor XOMA Ltd., a Bermuda exempted company, in connection with the discontinuance of XOMA Ltd. in Bermuda or the continuance of XOMA Corporation upon reincorporation of XOMA Ltd. in the State of Delaware, or otherwise) except to the extent
that such exemption from liability or limitation thereof is not permitted under the DGCL as currently in effect or as the same may hereafter be amended. This provision of the Registrant&#146;s certificate of incorporation does not eliminate the
directors&#146; fiduciary duty, and in appropriate circumstances, equitable remedies such as injunctive or other forms of non-monetary relief will remain available under Delaware law. In addition, each of the Registrant&#146;s directors will be
subject to liability for breach of the director&#146;s duty of loyalty to the Registrant, for acts or omissions not in good faith or involving intentional misconduct, for knowing violations of law, for actions leading to improper personal benefit to
the director, and for payment of dividends or approval of stock repurchases or redemptions that are unlawful under Delaware law. The provision also does not affect a director&#146;s responsibilities under any other law, such as the federal
securities laws or state or federal environmental laws. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The Registrant&#146;s bylaws also provide that the Registrant shall indemnify its
officers, directors and employees to the fullest extent possible except as prohibited by the DGCL. For purposes of the indemnification described in this paragraph, references to the Registrant include XOMA Ltd. as incorporated under Bermuda law
prior to the continuance of its existence as XOMA Corporation upon reincorporation under Delaware law. The Registrant will remain obligated with respect to the indemnification obligations of XOMA Ltd. arising prior to the Registrant&#146;s
reincorporation under Delaware law. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The underwriting agreement(s) that the Registrant may enter into may provide for indemnification by
any underwriters of the Registrant, its directors, its officers who sign the registration statement and the Registrant&#146;s controlling persons for some liabilities, including liabilities arising under the Securities Act. </P>

the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective

controlling the registrant pursuant to the foregoing provisions, the registrant has been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is therefore
unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of
any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. </P>
