ALISO VIEJO, Calif. and BOCA RATON, Fla., June 21, 2007 – Quest Software, Inc. (Nasdaq: QSFT) and ScriptLogic Corporation (www.scriptlogic.com) today announced a definitive agreement for Quest to acquire ScriptLogic in a cash transaction valued at approximately $90 million. The union is a natural fit for Quest, a market-leading provider of database, applications, and Windows management solutions, and privately-held ScriptLogic, a leading provider of systems lifecycle management solutions for Windows-based networks. The acquisition is subject to customary closing conditions and regulatory approvals, including expiration or termination of the Hart-Scott-Rodino waiting period, and is expected to be completed early in the third quarter of 2007.

In addition to expanding Quest’s presence in the small- and medium-sized business (SMB) space, the deal broadens Quest’s capabilities to support both Windows server-based and client-side needs as well as allowing ScriptLogic to benefit from Quest’s global footprint and extensive presence and knowledge in the Windows market.  

“Windows server-based services and products have become a cornerstone of Quest’s success and central to our opportunity for on-going growth,” said Vinny Smith, Quest CEO. “By adding ScriptLogic’s established strength in PC life-cycle management to complement our current offerings, we are increasing our ability to meet the Windows management needs of SMB customers while at the same time extending Quest’s direct sales model further with ScriptLogic’s successful high-volume, indirect reseller channel approach to market.”

ScriptLogic will operate as a wholly-owned subsidiary of Quest with Jason Judge, ScriptLogic CEO, reporting directly into Smith, and other key members of the management team remaining in place following the acquisition. With revenue around $20 million last year, the company has generated positive cash flow from operations and has more than 19,000 customers including many leading small and medium-sized businesses. 

“We are excited about becoming part of Quest as that will help us penetrate further into existing markets and give us the resources and expertise to expand into new markets,” said Judge. “We’ve been successful in building a strong reputation in the SMB market for Windows-based products that complement the existing Quest products. Now we’re looking forward to capitalizing on this momentum as part of Quest and taking our success to the next level.”
