Macrovision Acquires Zero G Software, Inc.; Extends Macrovision's Leadership in Maximizing the Value of Software on Any Platform.

SANTA CLARA, Calif. -- Macrovision(R) Corporation (Nasdaq:MVSN), the leader in Software Value Management, today announced that it has acquired privately-held Zero G Software, Inc. of San Francisco, Calif. Zero G is a leading provider of software deployment and delivery solutions for multi-platform operating system environments. Financial terms of the agreement were not disclosed, but Macrovision stated that the transaction would be EPS neutral in 2005, and accretive in 2006.

"The combined expertise of Zero G and Macrovision will provide software publishers and their customers with a seamless software installation experience across all platforms," stated Dan Stickel, EVP/GM, Software Technologies Group, Macrovision. "This acquisition further increases the market for our Software Value Management solutions, adds innovative technology and people to the company and enhances our multi-platform products."

"Software is facing a complexity crisis. With this agreement, two leaders in installation and software deployment have joined forces to simplify the installation of software in complex multi-platform, multi-server environments," stated Eric N. Shapiro, CEO of Zero G. "Zero G's enterprise-focused multi-platform installation products will complement and enhance Macrovision's industry-leading InstallShield(R) solutions, which are the de facto standard for Windows installations. In addition, Zero G customers will benefit from Macrovision's broad Software Value Management platform that enables publishers to flexibly price, package, license, protect and update their software applications."

Software installations are a critical factor in the overall value of software derived by customers. According to IBM Autonomic Computing research, 28% of all application failures are related to installation and configuration errors. The combination of Zero G and Macrovision technologies will benefit customers by simplifying the installation and management of enterprise software, offering the industry's premier installation experience on every platform. Both Macrovision and Zero G have been at the forefront of solutions for complex software installation and have worked closely with key standards bodies and industry partners including OASIS, WC3, IBM, HP and others to establish standards in the industry such as the Solution Deployment Descriptor Specification (SDD), also known as "Solution Installation."

"Enterprises are continually seeking new ways to reduce the total cost of managing, updating and installing software. Streamlining these processes starts with simplifying the management of large, interdependent software solutions running in increasingly complex IT environments," stated Audrey Rasmussen, vice president, Enterprise Management Associates. "By bringing Zero G into the fold, Macrovision can quickly deliver more value to both ISVs and their enterprise customers by automating time-consuming and error-prone manual software management processes."

Zero G Software will become part of Macrovision's Software Technologies Group and expand Macrovision's product portfolio in the Software Value Management category. Macrovision will continue to provide support for all Zero G products.
