Incentive Retention Plan

As previously disclosed, on June 9, 2010, Eclipsys Corporation (“Eclipsys”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Allscripts-Misys Healthcare Solutions, Inc., a Delaware corporation (which has changed its name to Allscripts Healthcare Solutions, Inc.) (“Allscripts”), 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”).

In connection with the transactions contemplated by the Merger Agreement, Eclipsys has established the Eclipsys Corporation Incentive Retention Plan (the “Plan”). The purpose of the Plan is to retain certain highly qualified individuals in the employment of the combined company after the Merger and motivate such individuals to achieve post-Merger performance objectives. Prior to the Merger, the Plan will be administered by the Eclipsys Compensation Committee, which is authorized to select the Plan’s participants. After the Merger, the Plan will be administered by the Allscripts Compensation Committee. Various employees will participate in the Plan, including the following Named Executive Officers of Eclipsys: Philip M. Pead, Chris E. Perkins, John P. Gomez, and W. David Morgan. The Plan awards for the Named Executive Officers consist of (i) cash awards equal to a potential maximum of $843,750 for Mr. Pead, $531,250 for Mr. Perkins, $593,750 for Mr. Gomez, and $275,000 for Mr. Morgan; and (ii) awards of performance-based restricted shares of Eclipsys common stock equal to a potential maximum of 54,189 shares for Mr. Pead, 34,119 shares for Mr. Perkins, 38,133 shares for Mr. Gomez, and 17,662 shares for Mr. Morgan. Like other shares of Eclipsys stock outstanding, each share of the restricted stock will be exchanged for 1.2 shares of Allscripts common stock in connection with the Merger. The cash awards vest in six equal installments on the following dates: on the date of the closing of the Merger and on the dates that are 6, 12, 16, 20 and 24 months after the closing of the Merger. One-half of the performance-based restricted shares are eligible to vest in each of the years ended September 30, 2011 and 2012; actual vesting depends upon the achievement of certain cost synergies and the booking of new integrated deals as established by the Compensation Committee, and no shares will vest if specified minimum performance levels are not achieved. All awards also will vest upon a termination due to death or disability, and termination by the company without cause and by the participant for good reason. Awards not previously vested are forfeited upon termination of employment for any other reason. The Plan and the awards will automatically terminate and all awards will be forfeited if the Merger does not occur by December 31, 2010.

Amendments to Executive Employment Arrangements

Between August 20 and August 24, 2010, Eclipsys entered into amendments to employment agreements (collectively, the “Amendments”) with each of Philip M. Pead, Chris E. Perkins, Brian W. Copple, John E. Deady, and John P. Gomez. The Amendments bring the employment agreements into compliance with the most recent guidance related to Code Section 409A’s rules regarding the time and form of deferred compensation payments in a number of respects and take advantage of an IRS correction procedure, IRS Notice 2010-6, to correct the Code Section 409A failures before the end of 2010 to avoid adverse tax consequences. All of the changes made by the Amendments are made to bring the documents into compliance with Code Section 409A.

Between August 20 and August 24, 2010, Eclipsys entered into amendments to preferred stock unit agreements (collectively, the “Amendments”) with each of Philip M. Pead, Chris E. Perkins, John E. Deady, and John P. Gomez. The Amendments bring the preferred stock unit agreements into compliance with the most recent guidance related to Code Section 409A’s rules regarding the time of deferred compensation payments and take advantage of an IRS correction procedure, IRS Notice 2010-6, to correct the Code Section 409A failures before the end of 2010 to avoid adverse tax consequences. All of the changes made by the Amendments are made to bring the documents into compliance with Code Section 409A.

On August 19, 2010, in consideration of the contributions of Jay Deady to Eclipsys and certain transitional assistance and the termination of Mr. Deady’s employment with Eclipsys in connection with the Merger, the Compensation Committee of the Board of Directors of Eclipsys approved the extension from 90 days to 365 days of the period of time following the termination of employment during which Mr. Deady may exercise the stock option for 400,000 shares of Eclipsys common stock at an exercise price of $21.03 per share, which was awarded to Mr. Deady in connection with commencement of his employment with Eclipsys.

Eclipsys and Brian Copple entered into a Supplemental Severance Agreement on August 17, 2010, which provides that when and if Mr. Copple becomes entitled to receive the severance benefits specified in his employment agreement with Eclipsys, then subject to the same conditions applicable to his right to receive those severance benefits, Eclipsys will provide to Mr. Copple a supplemental severance payment equal to the sum of one-half of his annual base salary in effect on the date of the agreement, plus one-half of his annual target bonus in effect on the date of the agreement, which sum shall be paid in a lump sum on the date that is six months plus one day after the date Mr. Copple’s employment terminates.
