Dear Ex Libris Customers,

Only a few weeks ago I wrote to tell you that Francisco Partners had completed the acquisition of Ex Libris.

In keeping with their plans to build and further invest in Ex Libris, I'm delighted to be able to share with you the news that Francisco Partners plan to make a further acquisition and today announced that a definitive acquisition agreement for the purchase of Endeavor Information Systems Inc. has been signed. We expect the deal to be completed by the end 2006 at which time the Endeavor organisation will merge with Ex Libris, operating as a single company with the Ex Libris name.

Both Ex Libris and Endeavor have a long tradition of providing leading edge, best of breed solutions to the academic and research library marketplace. With the combined strength of Ex Libris and Endeavor management, staff, customer bases and product lines we will become the largest supplier in this market segment and further strengthen our global presence.

Over the coming weeks the management teams in Ex Libris and Endeavor will be working together on a detailed integration plan for Endeavor staff and product roadmaps for our combined product portfolio. Regular updates will be provided and the attached FAQ document will serve to answer some of your immediate questions.

This is an exciting time for us all and a great opportunity for us to join two strong and visionary organisations. With our joint R&D we will be better placed to bring leading edge solutions to market quicker while continuing to build on our foundation of high quality service and partnership with all our customers.

I'm sure you will all join me in welcoming the Endeavor customers to the Ex Libris family. I look forward to meeting many of you at Mid Winter ALA and the Ex Libris seminars in the coming months and sharing with you our vision for our joint future building on the best of Ex Libris and Endeavor.

Sincerely yours,


Matti Shem Tov
President and CEO, Ex Libris
