Royalty&#146;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 <FONT STYLE="white-space:nowrap">out-license</FONT> 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, and our third-party licensees will not be able to market them. Other potential risks to XOMA Royalty meeting these expectations are described in more detail in XOMA Royalty&#146;s
most recent filing on Form <FONT STYLE="white-space:nowrap">10-Q</FONT> and in other filings with the Securities and Exchange Commission. Consider such risks carefully when considering XOMA Royalty&#146;s prospects. Any forward-looking statement in
