to herein as the "First Amended Land Lease"), pursuant to which Lessor leases
                  ------------------------
the Land (as defined therein) to Lessee and Lessee leases the Land from Lessor.

     B.  The First Amended Land Lease was modified by 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 (the "Second Amendment to Land Lease").   The First Amended Land Lease,

as amended by the Second Amendment to Land Lease, is referred to herein as the

amended by the Third Amendment to Land Lease, is referred to herein as the
"Third Amended Land Lease."

     D.  Advanced Micro Devices, Inc., a Delaware corporation (the "Guarantor"),
                                                                    ---------
executed and delivered to Lessor a Third Amended and Restated Guaranty, dated as
of August 21, 1995 and accepted by Lessor as of August 21, 1995 (the "Third
                                                                      -----

the obligations of Lessee under the Third Amended Land Lease and under the Third
Amended Building Lease (defined below).

     E.  The Third Restated Guaranty was modified by a certain
First Amendment to Third Amended and Restated Guaranty (the "First

Restated Guaranty, as amended by the First Guaranty Amendment, is
referred to herein as the "First Amended Guaranty")
                           ----------------------

Amendment to Building 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. 12271738, and (iii) a certain Third Amendment to Building Lease
dated as of August 21, 1995, and recorded on September 20, 1995 in the Official

valuable consideration, the receipt and adequacy of which are hereby
acknowledged, Lessor and Lessee hereby agree as follows (terms used but not
