Forward-Looking Statements/Explanatory NotesCertain statements contained in this press release 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, including statements regarding the potential expansion and accelerated growth of XOMA’s portfolio and the potential for this portfolio to generate sustained cashflows and positive returns over time.  In some cases, you can identify such forward-looking statements by terminology such as “anticipate,” “intend,” “believe,” “estimate,” “plan,” “seek,” “project,” “expect,” “may,” “will”, “would,” “could” or “should,” the negative of these terms or similar expressions.  These forward-looking statements are not a guarantee of XOMA’s performance, and you should not place undue reliance on such statements.  These statements are based on assumptions that may not prove accurate, and actual results could differ materially from those anticipated due to certain risks inherent in the biotechnology industry, including those related to the fact that our product candidates subject to out-license agreements are still being developed, and our licensees may require substantial funds to continue development which may not be available; we do not know whether there will be, or will continue to be, a viable market for the products in which we have an ownership or royalty interest; if the therapeutic product candidates to which we have a royalty interest do not receive regulatory approval, our third-party licensees will not be able to market them; and the impact to the global economy as a result of the COVID-19 pandemic.  Other potential risks to XOMA meeting these expectations are described in more detail in XOMA's most recent filing on Form 10-K and in other filings with the Securities and Exchange Commission.  Consider such risks carefully when considering XOMA's prospects.  Any forward-looking statement in this press release represents XOMA's beliefs and assumptions only as of the date of this press release and should not be relied upon as representing its views as of any subsequent date.  XOMA disclaims any obligation to update any forward-looking statement, except as required by applicable law.
