Eileen McPartland Joins Allscripts as

Chief Operating Officer

Former Oracle, SAP and Misys executive brings extensive

software technology operations experience

CHICAGO – June 1, 2009 – Allscripts announced today that Eileen McPartland has joined the company as Chief Operating Officer. Ms. McPartland brings to the position extensive operational experience from senior leadership roles within some of the world’s best-known technology software and services companies.

Ms. McPartland was most recently Executive Vice President of Global Sales and Services for Misys plc (FTSE: MSY.L), the global applications software and services company, where she was responsible for directing all customer-facing activities and over 2,500 people. She played a key role in delivering the Misys turnaround, implementing world-class processes and driving the transformation that helped to return Misys to a growth company.

“We are very excited that Eileen is joining Allscripts, building on our solid performance during the past year,” said Glen Tullman, Chief Executive Officer of Allscripts. “Her exemplary leadership, focus on operational excellence, and broad knowledge of the healthcare industry and of Allscripts will help ensure that we continue to deliver world-class client service while preparing to meet what we expect will be significant growth in demand for electronic health record solutions in the next few years.”

Prior to joining Misys in January 2007, Ms. McPartland was Senior Vice President, North America Consulting, at Oracle. In that position, she held responsibility for Oracle’s application, technology and Indian offshore consulting practices. From 1994 to 1998, Ms. McPartland held the position of Executive Vice President at SAP America, where she helped grow revenues from $100 million to over $1 billion.

Ms. McPartland joins Allscripts at a time when demand for the company’s solutions and services is likely to significantly increase in response to a new federal “economic stimulus” package that provides a maximum of between $44,000 and $64,000 in incentives for physicians to adopt and use Electronic Health Records. The American Recovery and Reinvestment Act of 2009 provides for the incentives over five years, beginning in fiscal 2011, for physicians who demonstrate meaningful use of a certified EHR system.

“I am excited to join the senior leadership team of Allscripts, the clear leader in healthcare information technology and the company best placed to help physicians benefit from the federal stimulus package by connecting their practices with our broad suite of industry leading solutions,” said Ms. McPartland. “I’m excited to put my experience to work helping the Company and our clients maximize the value of our solutions while taking full advantage of the Stimulus dollars available.”

Ms. McPartland will assume the duties of Chief Operating Officer from Lee Shapiro, who will continue in his role as President. Mr. Shapiro, who has been President of Allscripts since 2000, has held the interim COO position since October 2008. Mr. Shapiro will continue leading the company’s strategy, mergers and acquisitions, business development, emerging businesses and strategic partnerships.

“I am looking forward to partnering with Eileen on the significant business opportunities in front of Allscripts,” said Mr. Shapiro.

Ms. McPartland and Mr. Shapiro will both report directly to Mr. Tullman.
