IRVINE, CA--(Marketwire - March 26, 2009) - BIOLASE Technology, Inc. (NASDAQ: BLTI), the world’s leading dental laser company, today reported that it received a letter on March 23, 2009 from NASDAQ stating that BIOLASE is not in compliance with The NASDAQ Global Market Marketplace minimum stockholders’ equity continued listing requirement of $10 million. As of December 31, 2008, BIOLASE’s stockholders’ equity was approximately $9.4 million.

BIOLASE can either submit a detailed plan of compliance by April 7, 2009, advising NASDAQ of the action BIOLASE has taken, or plans to take, that would bring it into compliance or apply to transfer to the NASDAQ Capital Market, a continuous trading market that operates in the same manner as the NASDAQ Global Market.

The Company believes that, as of the date of this release, it is in compliance with all of the requirements for listing with the NASDAQ Capital Markets.

If BIOLASE chooses to submit a plan of compliance and NASDAQ does not accept the Company’s plan, NASDAQ may then initiate delisting proceedings from the NASDAQ Global Market, at which time BIOLASE may appeal NASDAQ’s determination to a Listing Qualifications Panel.
