Sunesis Pharmaceuticals Receives Extension From NASDAQ to Regain Listing Compliance

SOUTH SAN FRANCISCO, Calif., May 18  /PRNewswire-FirstCall/ -- Sunesis Pharmaceuticals, Inc. (NASDAQ:SNSS) announced today that on May 13, 2009, it received a letter from The NASDAQ Stock Market notifying Sunesis that it had been granted an extension of time to regain compliance with the minimum $10 million stockholders' equity requirement for continued listing set forth in NASDAQ Marketplace Rule 5450(b)(1)(A). Sunesis previously announced on April 17, 2009, that it had received a letter from NASDAQ notifying Sunesis that it was not in compliance with this requirement.

Under the terms of the extension, on or before July 28, 2009, Sunesis must furnish to the Securities and Exchange Commission and NASDAQ a publicly available filing that, among other things, evidences compliance with the minimum $10 million stockholders' equity requirement. In the event Sunesis does not satisfy the terms of the extension, Sunesis expects to be notified that its securities will be subject to delisting. At that time, Sunesis may request a hearing before a NASDAQ Listing Qualifications Panel.
