     This First Amendment to Lease Agreement (the "First  Amendment") is made on
January 24, 2001,  between Toubin Realty II, LLC, having offices located at 4000

Landlord;  and Geoworks  Corporation,  having a mailing  address of 960 Atlantic
Avenue, Alameda, California 94501, hereinafter designated as the Tenant.

     On or about  November  21,  2000,  Landlord  and  Tenant  executed  a Lease
Agreement whereby Tenant will lease approximately 20,000 billable square feet to
be  known  as  Building  B  behind  the  Grosso  Building  at 50  Route 9 North,
Morganville, New Jersey, as more particularly described in the Lease.

     Landlord and Tenant hereby amend their Lease  Agreement to reflect that the

Amendment,  all other terms and conditions of the Lease Agreement remain in full
