Eden Bioscience Corporation (NASDAQ: EDEN) today announced that it received a Nasdaq Staff Determination Letter on April 3, 2006 stating that the Company's common stock had not regained compliance with the $1 minimum bid price continued listing requirement set forth in Marketplace Rule 4310(c)(4) during the 180-day extension period provided the Company on October 10, 2005. Consequently, the Company's common stock is subject to delisting from The Nasdaq Capital Market at the opening of business on April 12, 2006. The Company has requested a hearing before a Nasdaq Listing Qualifications Panel to review the Staff Determination, which will stay the delisting action pending the issuance of a final decision by the Panel. There can be no assurance the Panel will grant the Company's request for continued listing.

To regain compliance with the minimum bid price requirement, the Board of Directors of the Company intends to effect a 1-for-3 reverse stock split of the Company's common stock. The Company can regain compliance with the minimum bid price requirement if the Company's common stock closes at or above $1 for 10 consecutive business days following the reverse stock split, in which case the Company would expect to receive notification from Nasdaq that it has regained compliance and that the hearing process will be terminated. However, there can be no assurance that the reverse stock split will cause the Company to regain compliance for the minimum bid price requirement for the required period of time.
