THEREFORE, for valuable consideration, receipt of which is hereby acknowledged, and in consideration of the hereinafter mutual promises, the parties hereto do agree as follows: 

        1.    TERM OF LEASE:    Pursuant to Lease Paragraph 44 ("Three (3) three (3) Year Options to Extend"), Tenant

        2.    BASIC RENT FOR EXTENDED TERM OF LEASE:    The monthly Basic Rent for the Extended Term of Lease shall be as

Landlord and Tenant are entering into another lease agreement dated January 22, 2002 for premises located at 34700 Campus Drive, Fremont, California (the "New Lease"). As a material part of the
consideration for the execution of said New Lease by Landlord, it is agreed between Landlord and Tenant that a default under this Lease, or a default under said New Lease may, at the option of

Lease Term has expired". 

        6.    HAZARDOUS MATERIALS:    Lease Paragraph 43 ("Hazardous Materials") shall be amended to include the
following: 

As
evidenced by their initials set forth immediately below, Tenant acknowledges that Landlord has provided Tenant with copies of the environmental reports listed on  Exhibit A ("Reports"), and Tenant

that Tenant has satisfied itself as to the environmental conditions of the Property and the suitability of such conditions for Tenant's intended use of the Property. To the best of Landlord's
knowledge as of the date of this Lease, except as noted in said Reports, no additional on site Hazardous Materials contamination exist on the Property; however, Landlord shall have no obligation to
further investigate.
