              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
                                   (Unaudited)


1.   Basis of Presentation

     The interim information contained in this report is unaudited but, in
management's opinion, includes all normal recurring adjustments necessary for a
fair presentation of results for the periods presented. Interim results may not
be indicative of results to be expected for the full year. The consolidated
financial statements should be read in conjunction with the Company's audited
consolidated financial statements for the year ended December 31, 2000 included
in its Annual Report on Form 10-K. The preparation of financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities, if any, at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ materially
from those estimates.

2.   Recent Accounting Prounouncements

     On June 29, 2001, the Financial Accounting Standards Board, or FASB,
approved the final standards resulting from its deliberations on the business
combinations project. The FASB is expected to issue two statements in late July
2001, Statement of Financial Accounting Standards No. 141, or FAS 141, on
Business Combinations and FAS 142 on Goodwill and Other Intangible Assets. FAS
141 will be effective for any business combinations initiated after June 30,
2001 and also includes the criteria for recognition of intangible assets
separately from goodwill. FAS 142 will be effective for fiscal years beginning
after December 15, 2001 and will require that goodwill not be amortized, but
rather be subject to an impairment test at least annually. Separately identified
and recognized intangible assets resulting from business combinations completed
before July 1, 2001 that do not meet the new criteria for separate recognition
of intangible assets will be subsumed into goodwill upon adoption. In addition,
the useful lives of recognized intangible assets acquired in transactions
completed before July 2001 will be reassessed and the remaining amortization
periods adjusted accordingly. The adoption of FAS 141 and 142 is not expected
have a significant impact on our financial position at transition.

     In June of 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities" (SFAS 133). XOMA adopted SFAS 133 on January
1, 2001. Because the Company currently holds no derivative financial instruments
and does not

                                      -4-


currently engage in hedging activities, adoption of SFAS 133 had no impact on
the Company's financial position or results of operations.

3.   Accrued Liabilities

     Accrued liabilities consist of the following (in thousands):

                                          June 30,              December 31,

                                        ============          ==============


4.   Revenue Recognition

     Research payments under collaborative arrangements and grants are
recognized as revenue based on research expenses incurred as provided for under
the terms of the arrangements.

     The Company previously recognized non-refundable license fees as revenue
when received and when all significant contractual obligations of the Company
relating to the fees had been met. Effective January 1, 2000, the Company
changed its method of accounting for non-refundable initial fees to recognize
such fees over the period of continuing involvement by the Company such as the
research and development period or the manufacturing period of the agreement, as
applicable. The Company believes this accounting policy is appropriate based on
guidance provided in SEC Staff Accounting Bulletin No. 101 - Revenue Recognition
in Financial Statements (SAB 101). As of January 1, 2000, there was no
cumulative effect of an accounting change as a result of the adoption of SAB 101
and there was no pro forma effect of the adoption of SAB 101 in any year
presented. In connection with the license and supply and development agreements
with Baxter Healthcare Corporation ("Baxter") on January 25, 2000, the Company
received $10.0 million as an initial, non-refundable fee. This initial fee was
deferred and is being amortized over the period of continuing involvement, which
period is estimated to be 36 months.

     In January of 2001, the Company entered into a strategic process
development and manufacturing agreement with Onyx Pharmaceuticals, Inc. ("Onyx")
which calls for the Company to scale-up production to commercial volume and
manufacture Onyx's CI-1042 product. The initial term of the agreement is five
years, with options to extend for additional

                                      -5-


periods. Terms of the agreement include an initial payment of $2.0 million,
payments for development work and material produced, and payments upon achieving
key milestones. XOMA's objectives are to increase the fermentation volume to
commercial scale, to improve the purification process, to seek FDA licensure of
its manufacturing facility for CI-1042, and to produce material for use in
clinical testing and for commercial sale upon approval. The initial payment was
deferred and is being amortized over five years.

     Milestone payments under collaborative arrangements are recognized as
revenue upon achievement of the incentive milestone events if it represents the
culmination of the earnings process and the Company has no future performance
obligations related to the milestone payment. Milestone payments are triggered
either by the results of our research efforts or by events external to the
Company, such as regulatory approval to market a product. Milestone payments and
amounts that are received in advance which are tied to future service
performance by the Company are recorded as deferred revenue and are amortized
over the period of continuing involvement.

5.   Comprehensive Loss

     Comprehensive loss includes certain changes in equity that are excluded
from net loss. Specifically, unrealized holding gains and losses in available
for sale investments, which were reported separately in shareholders' equity,
are included in accumulated other comprehensive income (loss). Comprehensive
loss and its components for the quarters ended June 30, 2001 and 2000 are as
follows (in thousands):

6.   Net Loss Per Common Share

     Basic and diluted net loss per common share is based on the weighted
average number of common shares outstanding during the period in accordance with
Financial Accounting Standard No. 128. Common share equivalents were not
included because they are antidilutive in all periods presented.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS


Results of Operations:

     Revenues in the second quarter of 2001 increased to $5.2 million, from $2.3
million in the second quarter of 2000. For the six-month periods ending June 30,
2001, revenuers were $8.1 million, compared with $4.9 million in the comparable
prior year period. Licensing revenue, primarily reflecting the amortization into
revenue of certain license fees and other payments received from Baxter
Healthcare Corporation and Onyx Pharmaceuticals, Inc., increased to $1.0 million
and $2.1 million in the three- and six-month periods ended June 30, 2001,
respectively, compared to $0.8 million and $1.4 million in the comparable prior
year periods. Contract revenue increased to $4.1 million and $6.0 million in the
three- and six-month periods ended June 30, 2001 from $1.4 million and $3.4
million in the comparable 2000 periods.

     Operating expenses increased to $11.6 million in the second quarter of 2001
from $9.0 million in the second quarter of 2000. For the six-month period ending
June 30, 2001, operating expenses were $21.6 million, compared with $17.7
million in the comparable 2000 period. This reflected increased spending on
Xanelim(TM) and XOMA's internal antibody programs, as well as expenses related
to litigation with Biosite Incorporated.

     Research and development expenses increased to $9.5 million and $17.9
million, respectively in the three and six-month periods ending June 30, 2001,
from $7.4 million and $14.6 million in the comparable prior year periods.
Spending in 2001 reflected increased development costs associated with
Xanelim(TM), ING-1, GENIMUNE(TM) and the Onyx CI-1042 product. This was
partially offset by reduced spending on NEUPREX(R).

     General and administrative expenses increased from $1.6 million and $3.1
million in the in the three- and six-month periods ending June 30, 2000, to $2.1
million and $3.7 million in the same 2001 periods.

     Interest expense was higher in the second quarter first six months of 2001
compared to 2000 due to higher interest rates and the higher average note
balance of the convertible subordinated notes due Genentech, Inc.

Liquidity and Capital Resources:

     XOMA ended the quarter with $71.8 million in cash, cash equivalents and
short-term investments, compared with $35.2 million at December 31, 2000. Net
cash used in

                                      -7-


operations in the first six months of 2001 was $11.5 million, compared with net
cash used in operations of $7.3 million in the second quarter of 2000. The prior
year cash flow benefited from $10.0 million in licensing fees received from
Baxter in January 2000, which is being recognized as revenue over a 36 month
period. See footnote 4, "Revenue Recognition," to the Consolidated Financial
Statements.

     Capital expenditures increased from $0.4 million in the first six months of
2000 to a net of $3.1 million in the current year period. Current year spending
included expenses related to the transfer of XOMA's technical development
operations from Santa Monica to Berkeley, as well as investments related to our
collaborative arrangement with Onyx.

     For the full year 2001, the Company currently expects its loss to be
somewhat lower than in 2000, with increased expense levels being more than
offset by higher revenues.

     Proceeds from the issuance of common shares, net, were $47.7 million for
the six months ended June 30, 2001, compared to $33.3 million for the comparable
period of the prior year. The amount for the first six months of 2001 resulted
primarily from a registered offering of 3,000,000 of the Company's common shares
in June 2001 for net proceeds of $43.3 million.

     The Company has been able to control its operating cash consumption by
carefully monitoring its costs. As a result, based on current spending levels
and taking into account the Onyx transaction, the Company believes its cash
position and resulting investment income are sufficient to finance the Company's
currently anticipated levels of spending through approximately the middle of
2004. Strategic arrangements with Onyx, Baxter and Genentech have reduced
Company spending levels by paying certain product development costs. The Company
continues to evaluate a variety of arrangements that would further strengthen
its competitive position and provide additional funding, but cannot predict
whether or when any such arrangement or additional funding will be consummated
or whether additional funding will be available. Without additional funding, the
Company will have to decrease or eliminate the development of some of its
products.

Quantitative and Qualitative Disclosures About Market Risk:

     Interest Rate Risk. The Company's exposure to market rate risk due to
changes in interest rates relates primarily to the Company's investment
portfolio. The Company does not use derivative financial instruments in its
investment portfolio. By policy, the Company places its investments with high
quality debt security issuers, limits the amount of credit exposure to any one
issuer, limits duration by restricting the term and holds investments to
maturity except under rare circumstances. The Company classifies its cash
equivalents as

                                      -8-


fixed rate if the rate of return on an instrument remains fixed over its term.
As of June 30, 2001, all the Company's cash equivalents are classified as fixed
rate.

     The Company also has a long-term convertible note due to Genentech in 2005.
Interest on this note of LIBOR plus 1% is reset at the end of June and December
each year and is therefore variable.

     The table below presents the amounts and related weighted interest rates of
the Company's cash equivalents and long-term convertible note at June 30, 2001:



                                                                               Fair Value            Average
                                                            Maturity        ($ in millions)       Interest Rate
                                                         -------------    -------------------   -----------------
                                                                                                
Cash equivalents, fixed rate                                  Daily              $ 71.8                  4.3%
Long-term convertible note, variable rate                      2005                43.0                  7.1%



     Other Market Risk. At June 30, 2001, the Company had a long-term
convertible note outstanding which is convertible into common shares based on
the market price of the Company's common shares at the time of conversion. A 10%
decrease in the market price of the Company's common shares would increase the
number of shares issuable upon conversion of either security by approximately
11%. An increase in the market price of Company common shares of 10% would
decrease the shares issuable by approximately 9%.

Forward Looking Statements:

     Statements made herein related to the estimated size of the Company's loss
for 2001, the estimated levels of its expenses and revenues for the balance of
2001, the sufficiency of its cash resources, present or future collaborative
arrangements and current plans for product development, or that otherwise relate
to future periods, are forward-looking statements within the meaning of Section
27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act
of 1934. 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. These risks, including those
related to size and timing of expenditures, unanticipated expenditures,
availability of funds, changes in the status of the existing collaborative
relationships, availability of additional collaboration opportunities, the time
or results of pending and future clinical trials, the ability of collaborators
and other partners to meet their obligations, market demand for products,
actions by the Food and Drug Administration of the U.S. Patent and Trademark
Office, and uncertainties regarding the status of biotechnology patents, are
discussed in the Company's most recent annual report on Form 10-K and in other
SEC filings.

                           PART II - OTHER INFORMATION


Item 1 Legal Proceedings. On July 5, 2001, XOMA filed a complaint in the United
     States District Court for the Northern District of California, San
     Francisco Division, against Biosite Diagnostics Incorporated (since renamed
     Biosite Incorporated). The complaint seeks monetary damages, injunctive and
     other relief for infringement of XOMA's bacterial cell expression
     technology patents in connection with certain Biosite technologies and
     collaborations. The suit also seeks relief for fraud and misrepresentation,
     breach of contract, misappropriation and unfair business practices in
     connection with three limited, non-exclusive licenses granted to Biosite
     under XOMA's bacterial cell expression technology.

Item 2 Changes in Securities and Use of Proceeds. On June 29, 2001, the Company
     completed a registered offering of 3,000,000 common shares. The managing
     underwriters in the offering were U.S. Bancorp Piper Jaffray, CIBC World
     Market Corp., Adams, Harkness & Hill and Arnhold & S. Bleichroeder, Inc.
     The common shares sold in the offering were registered under the Securities
     Act of 1933, as amended, on a Registration Statement on Form S-3 (Reg. No.
     333-50134) that was declared effective by the SEC on November 28, 2000.
     After deducting the underwriting discounts and offering expenses, the
     Company received net proceeds from the offering of approximately $43.3
     million. None of the net proceeds of the offering were paid directly or
     indirectly to any director, officer, general partner of ours or our
     associates, persons owning 10% or more of any class of equity securities of
     ours, or an affiliate of ours.

     The Company intends to use the net proceeds from this offering for general
     corporate purposes, including current research and development projects,
     the development of new products or technologies, equipment acquisitions,
     general working capital and operating expenses. Pending application of the
     net proceeds as described above, the Company has invested the net proceeds
     of the offering in short-term, investment-grade, interest-bearing
     securities.

Item 3 Defaults Upon Senior Securities. None.

Item 4 Submission of Matters to a Vote of Security Holders. On May 30, 2001, the
