- Isonics Corporation (NASDAQ: ISON), a company that is focused on the development and provision of products and services for the semiconductor and homeland security markets, announced today that its Common Stock will remain listed on the Nasdaq pending further consideration by The Nasdaq Stock Market's Board of Directors. Under Marketplace Rule 4809, The Nasdaq Board has decided to call

for review of the October 17, 2007 decision of the Nasdaq Listing and Hearing Review Council regarding Isonics' Common Stock and, pending further consideration, has stayed the Council's decision to suspend the Company's securities from trading. The review is scheduled for November 29, 2007.

Under the Nasdaq rules, Isonics is entitled to a hearing with a Nasdaq Listings Qualification Panel to attempt to obtain an additional period to regain compliance with the Nasdaq listing requirements. Isonics will provide the Panel with additional information regarding Isonics' proposed plan for regaining compliance with the Nasdaq listing requirements. The suspension of Isonics' listing will be stayed pending the Panel's decision. If the Panel does not find the Company's approaches to be acceptable, the Panel could immediately delist the Company's common stock. There can be no assurance the Panel will grant the Company's request for continued listing.

In the event that Isonics' common stock is delisted from Nasdaq's Capital Market, Isonics intends to work with its market makers as necessary to obtain quotation on the OTC Bulletin Board market.
