order dated October 4, 2001, which approved the assumption and assignment of
certain executory contracts and unexpired leases, including this Lease, pursuant

the Lease to Assignee and Assignee wishes to accept the assignment from Assignor
and assume all of Assignor's obligations under the lease.

                                   AGREEMENT

     1.   Effective Date of Assignment. The assignment in this Assignment shall
take effect on December 6th, 2001 at 11:59 p.m. Pacific Standard Time (the
"Effective Date"). Assignor shall deliver possession of the Premises to Assignee
on the Effective Date.

     2.   Assignment and Assumption. Assignor assigns and transfers to Assignee
all of its right, title and interest in the Lease as well as all appurtenances,
easements, licenses, permits, operating agreements and all other real property
interests and agreements relating to Assignor's use of the Premises, and
Assignee accepts the assignment and assumes and agrees to perform, from the
Effective Date, as a direct obligation to Landlord, all of the provisions in the
Lease.

     3.   Ground Lessor's Fund. The Parties acknowledge that a One Million
Dollar ($1,000,000) trust fund (the "Fund") is maintained at Wells Fargo Bank,
N.A. by Assignor for the benefit of Landlord and other ground lessors presently

for all trust administration costs and Assignor shall have no further
obligations with respect to the Fund.

     4.   Hold Harmless. If Assignee defaults under the Lease, Assignee shall
indemnify and hold Assignor harmless from all damages resulting from the
default. If Assignee defaults in its obligations under the Lease and Assignor
pays rent to Landlord; and/or fulfills any of the Assignee's other obligations
in order to prevent Assignee from being in default, Assignee shall immediately
reimburse Assignor for the amount of the rent or cost expended by Assignor,
together with interest on those sums at a rate of twelve percent (12%) per
annum. If Assignor defaults under the Lease at any time prior to Closing, as
defined in the Purchase and Sale Agreement, Assignor shall indemnify and hold
