RE:   Sun Solaris 2.x

Dear Ms. Carson:  As you are aware, Sun Microsystems, Inc. experienced a break-in of its computer
systems located in our Los Angeles office on or about June 30,1993. During the break-in, a substantial
portion of the source code of Sun's Solaris 2.x software product was apparently copied and removed. 
Solaris software is a UNIX-based product originally licensed by Sun from AT&T.; In March of 1994 Sun
bought out its original license with AT&T; with a lump sum payment of more than $80 million. In addition,
Sun has invested very heavily for more than ten years in the continued development of the Solaris
software and values the current product in the hundreds of millions of dollars. 

Sincerely,
Lee Batch
Vice President, Intellectual Property Law
