Boca Raton, FL – November 12, 2007 – ScriptLogic(r) Corporation, www.scriptlogic.com, a leading provider of systems lifecycle management solutions for Microsoft(r) Windows(r)-based networks and a wholly owned subsidiary of Quest Software, Inc., today announced that it has acquired substantially all the assets of Pittsburgh, Pennsylvania-based Mattus, Inc., d/b/a Kemma Software. The acquisition enhances ScriptLogic’s desktop management product portfolio by offering customers the BridgeTrak Suite®, a powerful help desk software solution that tracks issues reported by end users from entry to remediation.

The BridgeTrak Suite provides IT organizations a way to track user computing problems, such as issues with their own desktop machines, remote access, etc., allowing IT administrators to easily and efficiently record, manage and resolve reported problems. BridgeTrak, which is available as a Windows and Web-based client interface, complements ScriptLogic’s existing desktop management solutions since administrators can use ScriptLogic’s Desktop Authority® to fix the desktop issues that are reported through the BridgeTrak system. In 2008, ScriptLogic plans to further integrate BridgeTrak with the existing Desktop Authority product line.

“Our customer base has been asking for a help desk solution to complete our desktop management offering,” said Jason Judge, CEO of ScriptLogic Corporation. “Kemma Software’s development team has done a superior job building a solution that offers the features most often requested by help desk professionals, and we are eager to add help desk tracking and reporting to our customers’ toolbox.”

BridgeTrak 7.0, an easy-to-use, scalable, client-server application, provides IT administrators and external support professionals the ability to review all data related to issues that have been reported to the help desk, improving the efficiency of IT staff in managing problems and reducing the time end-users are not productive because their machines are in need of attention. A free 30-day evaluation of BridgeTrak 7.0 is available at www.kemma.com.

“Over the past few years, we have seen an increase in customer demand for BridgeTrak. Now, by joining forces with ScriptLogic, we have the ability to deliver the product to a vast audience of IT administrators and help desk professionals through a strong sales force,” said Jeff Muschar, founder and CEO, Kemma Software. “We look forward to further enhancing the product to integrate directly with ScriptLogic’s Desktop Authority to provide a solution that will not only facilitate the reporting and tracking of issues, but also prevention and resolution.”

ScriptLogic plans to retain the Kemma Software staff.
