Francisco Partners to Acquire Endeavor Information Systems from Elsevier

Endeavor to be merged with Ex Libris, to create global leader in library software and services

Menlo Park, London, Chicago, Amsterdam, Jerusalem, November 21, 2006 - Francisco Partners, one of the world's largest technology-focused private equity funds, today announced that it has entered into a definitive agreement with Elsevier for the acquisition of 100% of the shares of Endeavor Information Systems, Inc., an Elsevier company. Endeavor will be merged with Ex Libris, which was acquired by Francisco Partners earlier this year. The combined entity will be a leading force in the library software and services marketplace and will retain the Ex Libris Group name and be headed by Matti Shem Tov, president and chief executive officer of Ex Libris.

The acquisition of Endeavor will establish the new Ex Libris Group and its portfolio of library systems and services as the clear choice for libraries seeking proven solutions that are both forward looking and cost effective. In the coming years, the company will continue the development and support of flagship integrated library systems from both companies, Ex Libris ALEPH® 500 and Endeavor’s Voyager®. New versions of both systems will be released as planned in 2007. The Ex Libris and Endeavor management teams will be working closely over the coming weeks, in consultation with industry leaders and customers, to complete the roadmap for the combined product portfolio.

Together, the Ex Libris and Endeavor customer communities include nine of the top ten universities in the world and 39 of the top 50, according to Newsweek International Edition ("The Top 100 Global Universities"); 25 national libraries; and five of the six largest libraries in the world.

"Today we are combining two market-leading companies to create the most powerful library software portfolio in the industry," said Matti Shem Tov, Ex Libris Group president and CEO. "Leveraging the extensive experience and technologies as well as the dedicated, skilled staff of both companies, we will now be even better equipped to provide our customers with next-generation library products. We welcome Endeavor's customers to the Ex Libris community and, with this important acquisition, look forward to delivering significant value for our combined customer base."

"The decision to seek a new owner for Endeavor business was made after we carefully considered the rapid pace of change in the library software and services marketplace," said Herman van Campenhout, CEO, Elsevier Science & Technology. "Based on that review, we concluded that Endeavor, its employees, and its customers will greatly benefit from becoming part of a company, such as Ex Libris, that is solely focused on leading the library software market."

Andrew Gray, a principal with Francisco Partners, commented, "Ex Libris and Endeavor are natural partners. With joined forces, the Ex Libris Group will carry on the two companies' longstanding tradition of collaborating with libraries and industry stakeholders to establish industry standards and will continue to deliver solutions that best serve the needs of libraries, information centers, and researchers."

"This is an exciting time for Ex Libris and Endeavor as it represents the coming together of two strong and visionary organizations," noted Endeavor CEO Roland Dietz. "With our joint research and development, we will be better positioned to bring leading edge solutions to market more quickly while continuing to build upon our foundation of high quality service and partnership with our respective customers."
