SAN MATEO, Calif.--(BUSINESS WIRE)--April 4, 2000

Siebel Systems, Inc. (Nasdaq:SEBL), the world's leading supplier of eBusiness Application software, today established the Siebel Scholars Program at the world's most prestigious business and computer science schools.

Based on academic merit and leadership qualities, five students from each institution will be honored as Siebel Scholars every year and receive $25,000 to help defray tuition costs and fees for the second year of their graduate studies.

Deans from the eleven institutions will select the first 55 Siebel Scholars before the end of this academic year. In addition, an alumni association of all Siebel Scholars will convene at a conference to be hosted annually by one of the participating schools.

"The Siebel Scholars Program gives the School an opportunity to recognize those students who have demonstrated a commitment to excellence and outstanding leadership," said Kim Clark, dean of the Harvard Business School.

"The graduate programs at these universities have made great contributions to industry and society, both here in Silicon Valley and worldwide," said Thomas M. Siebel, chairman and CEO of Siebel Systems. "Siebel Systems wishes to support those efforts on a personal level, and the Siebel Scholars Program is our way of helping develop the talent."

The Siebel Scholars Program has been established at the following leading educational institutions:

      --  Carnegie Mellon University, School of Computer Science

      --  Massachusetts Institute of Technology, School of Engineering

      --  Stanford University, School of Engineering

      --  University of California at Berkeley, College of Engineering

      --  University of Illinois at Urbana-Champaign, College of
        Engineering

      --  Harvard Business School

      --  Massachussetts Institute of Technology, MIT/Sloan School of
        Management

      --  Northwestern University, J.L. Kellogg School of Management

      --  Stanford University, Graduate School of Business

      --  University of Chicago, Graduate School of Business

      --  University of Pennsylvania, The Wharton School

Each institution is receiving a $2.6 million endowment, which will be invested, so the proceeds fund the program at each university in perpetuity.

In 1999, Siebel Systems initiated an educational program that was highlighted by a donation of $32 million by Thomas M. Siebel, chairman and CEO of Siebel Systems, to the University of Illinois to fund the construction of the Siebel Center for Computer Science; by a donation of $3 million to Stanford University to sponsor the "Thomas M. Siebel Professorship in Business Leadership;" and by a donation of $3 million by Siebel Systems to the Children's Scholarship Fund, a charitable organization that provides low-income children with a choice of private educational opportunities.
