Isonics Receives Letter From Nasdaq.

GOLDEN, Colo. -- Isonics Corporation (NASDAQ: ISON), a provider of innovative solutions for the homeland security and semiconductor markets, announced today that on July 10, 2006, it received a letter from the Nasdaq Stock Market notifying the Company that for the last 30 consecutive business days, the bid price of the Company's common stock has closed below the minimum $1.00 per share price requirement for continued inclusion under Nasdaq Marketplace Rule 4310(c)(4).

Isonics has been granted 180 calendar days to regain compliance with the Nasdaq Capital Market $1.00 minimum bid price rule. If at any time before January 9, 2007, the bid price of the company's common stock closes at $1.00 per share or more for a minimum of 10 consecutive business days, Nasdaq will notify the company that it is in compliance with the Rules. If Isonics fails to obtain compliance, as long as it meets the Nasdaq Capital Market initial listing criteria as set forth in Marketplace Rule 4310(c), except for the bid price requirement, the Company would be granted an additional 180 calendar days to obtain compliance. If the Company does not regain compliance within these allotted compliance periods, Nasdaq staff will notify the company that its common stock will be delisted from The Nasdaq Capital Market. Isonics would then be entitled to appeal the Staff's determination to a Nasdaq Listing Qualifications Panel and request a hearing.
