As previously reported, on June 9, 2010, Allscripts-Misys Healthcare Solutions, Inc., a Delaware corporation (“Allscripts”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Eclipsys Corporation, a Delaware corporation (“Eclipsys”), and Arsenal Merger Corp., a Delaware corporation and wholly owned subsidiary of Allscripts (“Merger Sub”). The Merger Agreement provides that, upon the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub will merge with and into Eclipsys, with Eclipsys surviving as a wholly owned subsidiary of Allscripts (the “Merger”).

Subject to the terms and conditions of the Merger Agreement, which has been approved and adopted by boards of directors of both Allscripts and Eclipsys, at the effective time of the Merger (the “Effective Time”), each share of Eclipsys common stock, par value $0.01 per share, issued and outstanding immediately prior to the Effective Time, other than those shares owned by Allscripts, Eclipsys or any of their respective subsidiaries, will be converted into the right to receive 1.2 shares of Allscripts common stock, par value $0.01 per share.

As previously reported, in connection with the Framework Agreement, dated as of June 9, 2010, among Allscripts, Misys plc and Eclipsys, Allscripts has signed a commitment letter with JPMorgan Chase Bank, N.A., Barclays Bank PLC, UBS Loan Finance LLC and certain of their affiliates for a $570 million senior secured term loan facility and a $150 million senior secured revolving facility, the (“Financing”).

Filed as exhibits hereto are certain historical financial statements of Eclipsys and unaudited pro forma condensed combined financial statements giving effect to the Merger, the Financing and the other transactions described in the accompanying notes. There can be no assurance that the Merger, the Financing and the other transactions described in the accompanying notes will be consummated on the terms described herein or at all.

The foregoing statements regarding Allscripts’ intentions with respect to the proposed Merger, the Financing and other transactions described above are forward-looking statements under the Private Securities Litigation Reform Act of 1995, and actual events could vary materially from the statements made.

Effective June 1, 2009, we adopted accounting guidance which states that unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are considered participating securities and shall be included in the computation of earnings per share pursuant to the two-class method. We are filing updated Selected Financial Data to reflect the adoption of this accounting guidance on a retrospective basis.
