XOMA Announces NASDAQ Matter Resolved With Letter of Reprimand

No Change in Listing Status

Emeryville, CA


BERKELEY, Calif., Dec. 9, 2009 (GLOBE NEWSWIRE) -- XOMA Ltd. (Nasdaq:XOMA), a leader in the discovery and development of therapeutic antibodies, announced that it received a Letter of Reprimand from the staff of The NASDAQ Stock Market LLC on December 8, 2009 for non-compliance with NASDAQ's Listing Rule 5635(d)(2) in connection with XOMA's previously-announced common share financing completed on September 30, 2009. The issuance of this letter completed the NASDAQ staff's review of the matter which was referenced in the previously-disclosed November 13, 2009 letter to XOMA. XOMA's common shares will remain listed on The NASDAQ Global Market.

The letter states that, although the NASDAQ staff determined that the company failed to comply with the rule, it was appropriate to close the matter with a Letter of Reprimand in light of the apparent inadvertent nature of the violation, the company's reliance on its outside advisors, the company's efforts to remedy the transaction and assure future compliance, and because the company has not demonstrated a pattern of non-compliance with NASDAQ's continued listing rules.
