CHICAGO (September 16, 2008) –

Allscripts Healthcare Solutions, Inc. (“Allscripts”) (Nasdaq: MDRX), the leading provider of clinical software, connectivity and information solutions that physicians use to improve healthcare, announced today that Misys plc (“Misys”) has issued a press release regarding recent events at Lehman Brothers. In connection with the proposed transactions contemplated by an Agreement and Plan of Merger dated as of March 17, 2008 by and among Allscripts, Misys, Misys Healthcare Systems, LLC (“MHS”) and Patriot Merger Company, LLC (the “Merger Agreement”), Lehman Brothers committed to a $305 million term and revolving credit facility agreement dated March 19, 2008 (as amended and restated on July 22, 2008) with Misys in order to fund a portion of the $330 million payment by Misys to Allscripts contemplated by the Merger Agreement.

Misys has stated that it has been unable to confirm whether Lehman Brothers will be able to fulfill its role under this facility and has therefore commenced the process of identifying other funding alternatives and is in discussions with several other debt providers. The consummation of the transactions contemplated by the Merger Agreement is not subject to a financing condition.

Given the circumstances, Allscripts intends to adjourn its 2008 annual meeting of stockholders scheduled for Monday, September 22, 2008 to October 6, 2008, the same date to which Misys has determined to adjourn its extraordinary general meeting. Allscripts continues to support the transactions contemplated by the Merger Agreement, and is working together with Misys to bring the transactions to a successful conclusion. Glen Tullman, Chief Executive Officer of Allscripts, added, “While the events surrounding Lehman Brothers are unfortunate, we nevertheless remain excited about the transactions with Misys and believe they are in the best interests of our stockholders and clients.”
