MDRNA, Inc. Regains Full Compliance With All Marketplace Rules to Remain on the NASDAQ Global Market

Receives Letter From NASDAQ Regarding Compliance With NASDAQ Marketplace Rule 5450(b)(2)(A)


BOTHELL, WA--(Marketwire - June 23, 2009) - MDRNA, Inc. (NASDAQ: MRNA) announced today that on June 22, 2009, it received a letter from The NASDAQ Stock Market, LLC notifying the Company that it has regained full compliance with all requirements for remaining on The NASDAQ Global Market, specifically NASDAQ Marketplace Rule 5450(b)(2) (the "market value standard"), which requires, among other things, a minimum market value of listed securities of $50.0 million (NASDAQ Marketplace Rule 5450(b)(2)(A)).

"We are pleased to have regained full compliance with all Marketplace Rules to remain on the NASDAQ Global Market," stated J. Michael French, President and CEO. "Since receiving a non-compliance notice from NASDAQ in the fall of 2008, our goal has been to remain listed on the NASDAQ Global Market. Our ability to regain compliance with all of NASDAQ's listing requirements is a testament to our scientific team and our industry leading RNAi drug discovery platform. Validating our platform through two non-exclusive licensing transactions with major pharmaceutical companies, selling our contract manufacturing operations, retiring our debt to GE Capital Corporation over a five-month period, and raising over $10 million in an equity financing all contributed to both the strength of our balance sheet and our ability to comply with all NASDAQ listing requirements. We will continue to build shareholder value with the same dedication and commitment to shareholders that led us to this point."

On May 26, 2009, MDRNA announced that had regained compliance with NASDAQ Marketplace Rule 5450(a)(1), which requires a minimum $1.00 closing bid price for at least 10 consecutive trading days.
