Quest Software, Inc. (Nasdaq: QSFT), a leading provider of application, database and Windows management solutions, today announced that it has completed the acquisition of Imceda Software, a privately-held leader in database administration products for SQL Server databases. The acquisition expands Quest’s product portfolio to include backup and recovery and security auditing solutions and enables Quest to offer one of the most comprehensive product sets for the growing SQL Server database market.

With more than 3,000 licensed customers, Imceda’s LiteSpeed™ is a market-leading rapid backup and recovery solution for SQL Server. It provides integrated compression and encryption in the backup process, which helps companies save thousands of dollars in storage costs and eliminate hours from traditional backup and restore times.

Quest will maintain the brand and technological integrity of the well-known LiteSpeed product line. Quest also intends to integrate Imceda’s other database and storage management software products into its current line of solutions for database management.

Under the terms of the definitive agreement announced on April 26, 2005, Quest is paying $46.5 million in cash, issuing 942,855 shares of Quest Software Common Stock and assuming Imceda options that will convert into options to purchase approximately 325,000 Quest shares.
