News Releases

RICHMOND, Va., June 20, 2008 /PRNewswire-FirstCall via COMTEX News Network/ -- Insmed Inc. (Nasdaq: INSM), a developer of follow-on biologics and biopharmaceuticals, today announced that it intends to request a hearing before The NASDAQ Listing Qualifications Panel ('the Panel") to appeal an earlier Staff Determination to delist the Company's common stock from The NASDAQ Capital Market. 

Insmed received a letter from The NASDAQ Stock Market ("NASDAQ") on June 17, 2008 indicating that the Company had not regained compliance with NASDAQ's minimum bid price requirement of $1.00 per share for continued listing of Insmed's common stock on The NASDAQ Capital Market as set forth in Marketplace Rule 4310(c)(4) (the "Staff Determination"). As a result, the Company's common stock would be subject to delisting unless Insmed requests a hearing before the Panel. Following procedures set forth in The NASDAQ Marketplace Rule 4800 series; the Company intends to request a hearing before the Panel to review the Staff Determination. The hearing request will stay the delisting of Insmed's common stock, pending the decision of the Panel following the hearing, allowing the Company's common stock to continue to trade on The NASDAQ Capital Market. There can be no assurance, however, that the Panel will grant Insmed's request for continued listing of its common stock on The NASDAQ Capital Market. 

In the event that the Panel determines not to grant the Company's request for continued listing of its common stock on The NASDAQ Capital Market, Insmed's common stock may become eligible for quotation and trading on the OTC Bulletin Board.
