Nuvelo Receives Nasdaq Notification

SAN CARLOS, Calif., May 2 /PRNewswire-FirstCall/ -- Nuvelo, Inc. (Nasdaq: NUVO) today announced that it received a staff deficiency letter from the Nasdaq Stock Market on May 1, 2008 indicating that, for the last 30 consecutive business days, the bid price of Nuvelo's common stock has closed below the minimum $1.00 per share requirement for continued listing under Marketplace Rule 4450(a)(5).

The letter stated that under Marketplace Rule 4450(e)(2), Nuvelo will be provided with 180 calendar days, or until October 28, 2008, to regain compliance with Marketplace Rule 4450(a)(5). To regain compliance, the bid price of Nuvelo's common stock must close at $1.00 per share or more for a minimum of 10 consecutive business days, anytime before October 28, 2008.

If Nuvelo does not regain compliance with Marketplace Rule 4450(a)(5) by October 28, 2008, but meets The Nasdaq Capital Market initial inclusion criteria set forth in Marketplace Rule 4310(c), except for the bid price requirement, it may apply to transfer the listing of its securities to this market and, if accepted, be provided with an additional 180 calendar day compliance period to demonstrate compliance. If Nuvelo is not eligible for an additional compliance period at that time, Nasdaq Staff will provide written notification that Nuvelo securities will be delisted. Upon such notice, Nuvelo may appeal the Nasdaq Staff's Determination to the Nasdaq Listing Qualifications Panel. There can be no assurance that, if Nuvelo does appeal the Nasdaq Staff's Determination, that such appeal would be successful.
