On June 16, 2010, Integral Systems, Inc. (the “Company”) appointed Christopher B. Roberts, 55, to the office of Chief Financial Officer of the Company, effective June 28, 2010. In connection with Mr. Roberts’s appointment, the Company entered into an offer letter (the “Offer Letter”) with Mr. Roberts, outlining the terms of Mr. Roberts’s “at-will” employment with the Company.

Since 2007, Mr. Roberts has served as the Controller and Director of Contracts at Laguna Ventures, Inc., a private government contractor, where he is responsible for financial planning, forecasting, reporting and accounting management. Prior to joining Laguna Ventures, Mr. Roberts was the Finance Director for Pearson Analytic Solutions, Inc., a provider of professional services and IT systems to U.S. government defense and intelligence agency customers, a position he held from 2006 to 2007. In 1998 Mr. Roberts co-founded PixSell Inc., a professional service company specializing in geospatial information management systems and remote sensing, and served as Chief Executive Officer and Chief Financial Officer of PixSell Inc. from 1998 until 2005. Prior to that time, Mr. Roberts worked in financial management, contracts administration, business development and compliance positions for several technology companies in the Washington, D.C. area, including System Planning Corporation, CTA Incorporated and Atlantic Aerospace Electronics Corporation. Mr. Roberts holds a Masters of Science in Business Management degree from the Massachusetts Institute of Technology, a law degree from the University of Virginia School of Law and a Bachelor of Science degree from the Massachusetts Institute of Technology.

Under the terms of the Offer Letter, Mr. Roberts will receive a base salary of $200,000 per year and be eligible to participate in the Company’s Management Incentive Plan, with a target bonus of fifty percent of his base salary. Any actual bonus will be based on corporate and individual performance parameters, in accordance with the terms of the Management Incentive Plan. Subject to approval of the Compensation Committee of the Board of Directors, the Company will issue to Mr. Roberts options to purchase 30,000 shares of the Company’s common stock. Such stock options will be subject to the vesting restrictions and other terms and conditions set forth in the Company’s 2008 Stock Incentive Plan and the Company’s standard form of award agreement for options under that plan. In addition, Mr. Roberts is eligible to participate in the Company’s standard employee benefits program, which includes vacation and sick time, a 401(k) retirement plan and insurance benefits.

The preceding summary of the Offer Letter is qualified in its entirety by reference to the text of the Offer Letter, which is filed with this Current Report on Form 8-K as Exhibit 10.1.
