SUBJECT: Allscripts and Eclipsys to Form One Company … All-Employee Meeting at 11 am EDT Today

All,

I have some exciting news to share. As you may have heard in my voicemail, Allscripts and Eclipsys, leading providers of software and information solutions in the ambulatory and acute markets respectively, have agreed to merge. Additionally, we announced that Allscripts will buy back a majority of our stock currently held by Misys. The legacy Misys Healthcare business will, of course, remain part of Allscripts and, in turn, of the merged company.

For those of you who may not know, Eclipsys is a leading provider of solutions and services for hospitals and is well known for having the highest Computerized Physician Order Entry (CPOE) utilization in the market. That’s the new metric of success for hospital systems. Combine that with our focus on driving physician utilization of Electronic Health Records and you end up with a new leader in driving meaningful use of the technology the Federal Government is supporting with more than $30 billion in stimulus funding.

By combining Allscripts and Eclipsys we will have the industry’s largest network of clients on the most advanced product platform resulting in a single patient record. One network. One platform. One Patient. A great vision that is going to quickly become a reality.

I will serve as CEO of the new company, Eclipsys CEO and President Phil Pead will serve as Chairman and Bill Davis will serve as CFO. The remainder of the leadership team for the combined company will be drawn from the leadership of both Allscripts and Eclipsys. Don’t worry, with a company this large and the size of the opportunity in front of us, we expect, not unlike our merger with Misys Healthcare, to continue hiring.

Later this morning, Phil and I will be jointly hosting a companywide Town Hall meeting. Please plan to join us at 11:00 EDT. Participation instructions follow at the end of this message. In the meantime, please visit www.oneallscriptseclipsys.com for more information, including a video of Phil and me talking about the agreement, an FAQ document, and the press release.

I am excited about this merger. It’s the next natural step on the road to realizing our vision of a connected system of health. Combining these two companies into one will uniquely position us for success. Consider this:

One Network. With a client base of 180,000 physicians, 1,500 hospitals and 10,000 post acute organizations, our combined company will form the largest network in healthcare. This significant footprint will enable us to connect providers and patients wherever care is delivered – in the hospital, in small or large physician practices, in extended care facilities or in the patient’s home.


One Platform. Both companies already use common platforms, including Microsoft.NET and other advanced technologies, which will enable us to quickly deliver an integrated offering. We will bring together the Allscripts industry-leading electronic health record, practice management and comprehensive portfolio of solutions for physicians and post acute care organizations with Eclipsys’s leading enterprise and performance management solutions for hospitals. In addition to connecting our own solutions, we will lead with an ‘open architecture’ approach that will simplify connectivity with third-party applications.

One Patient. Combining one network of clients on one platform, Allscripts and Eclipsys will be positioned to deliver a single patient record to all providers within an organization and across a community. By bringing to market a complete portfolio of clinical, financial, connectivity and information solutions, the company will enable the delivery of the information and insight providers need to create a seamless patient experience with improved care at a lower cost.

We expect that the merger will be completed this Fall. It is subject to customary closing conditions. In the meantime, we will continue to operate as two separate organizations in the same way that we do today.

This would not have been possible without all of your hard work and commitment to our clients. Thank you for all you have done to put us in the position to capture this incredible opportunity in front of us. I look forward to working together with all of you to make this merger a great success for our clients, our shareholders, and for you.

 

Sincerely,

Glen Tullman

Chief Executive Officer
