     B.  Lessor and Lessee entered into that certain Second Amendment to

     ------------------------------ 

     C.  The Second Amended Building Lease was modified by a certain Third

September 20, 1995 in the Official Records of Santa Clara County, California, as
Document No. 13020001  (the "Third Amendment to Building Lease").  The Second

Restated Guaranty"), pursuant  to  which  the  Guarantor  guarantied  to  Lessor
- -------------------
the obligations of Lessee under the Third Amended Building Lease and under the
Third Amended Land Lease (defined below).

     E.  The Third Restated Guaranty was modified by a certain

                           -----------------------

recorded on January 5, 1993 in the Official Records of the Recorder of Santa
Clara County, California as Document No. 11720033, (ii) a certain Second
Amendment to Land Lease dated as of December 17, 1993, and recorded on December
20, 1993 in the Official Records of Santa Clara County, California, as Document
No. 12271737, and (iii) a certain Third Amendment to Land Lease, dated as of
