The Company announced that it will request a hearing before the NASDAQ Listing Qualifications Panel (the “Panel”) in response to the receipt of a NASDAQ Staff Determination letter on August 23, 2006 indicating that the Company is not in compliance with the filing requirements for continued listing as set forth in Marketplace Rule 4310(c)(14). As anticipated, the letter was issued in accordance with NASDAQ procedures due to the delayed filing of the Company’s Form 10-QSB for the quarter ended June 30, 2006. Pending a decision by the Panel, National Mercantile Bancorp shares will remain listed on the NASDAQ Stock Market.
