                                   AGREEMENTS

         In consideration of the premises and other good and valuable
consideration, Sublessor and Sublessee agree as follows:

         1. PREMISES SUBLEASED & TERM. Sublessor hereby subleases to Sublessee

         4. ACCEPTANCE. Sublessee acknowledges that it has inspected the
Sublease Premises demised hereunder, and is fully satisfied with their condition
and accepts the same, "AS IS." Sublessor has made no representation or
warranties of any nature whatsoever with regard to the Sublease Premises, other
than those set forth herein, and Sublessor shall have no obligation or duty with
regard to preparation of the Sublease Premises for occupancy by Sublessee.

         5. BASE LEASE INCORPORATED. The provisions of the Base Lease are,
except as otherwise herein specifically provided, hereby incorporated in this
Sublease with the same effect as if entirely rewritten herein, and shall fix the
rights and obligations of the parties hereto with respect to the Sublease
Premises with the same effect as if Sublessor and Sublessee were, respectively,
the landlord and tenant named in the Base Lease. Sublessee hereby covenants to
perform the covenants and undertakings of Sublessor as tenant under the Base
Lease to the extent the same are applicable to the Sublease Premises during the
term of this Sublease, and agrees not to do or permit to be done any act which
shall result in a violation of any of the terms and conditions of said Base
lease. Except as otherwise specifically provided herein, Sublessee is to have
the benefit of the covenants and undertakings of Landlord in the Base Lease to
the extent the same are applicable to the Sublease Premises during the term of
this Sublease. It is expressly understood and agreed, however, that Sublessor is
not in the position to render any of the services or to perform any of the
obligations required of Landlord by the terms of the Sublease, and that
performance by Sublessor of its obligations hereunder are conditioned upon due
performance by owner of its corresponding obligations under the Base Lease. It
is further understood and agreed, therefore, that notwithstanding anything to
the contrary contained in this Sublease, Sublessor shall not be in default under
this Sublease for failure to render such services or perform such obligations
required by Sublessor by the terms of this Sublease that are the responsibility
of the Landlord under the Base Lease, but Sublessor agrees to take all
responsible measures to insure that Landlord performs said obligations. The term
"reasonable measures" shall not include legal action against Landlord for its
failure to so perform unless Sublessee agrees to pay all costs and expenses in
connection therewith.

         6. SUBORDINATE TO BASE LEASE. This Sublease is subject and subordinate
in all respects to said Base Lease. Sublessee acknowledges that it has received
a copy of said Base Lease, which is attached hereto as Exhibit B.

         7. HOLDOVER. Sublessee shall promptly vacate the sublease Premises upon
expiration or termination of this Sublease. Any holding over by Sublessee beyond
the expiration date of this Sublease shall be deemed unlawful unless expressly
consented to by Sublessor in writing, and Sublessor shall be entitled to any and
all remedies in law or in equity by reason of such unlawful holding over by
Sublessee. Sublessee agrees to indemnify and save Sublessor harmless against and
from any and all loss, cost, expense and liability incurred by Sublessor under
the Base Lease by reason of any such holding over.

         8. INDEMNIFICATION. Sublessee shall indemnify and save harmless
Sublessor against and from any and all liability, damage, expense, cause of
action, suits, claims or judgments for injury or death to persons or damage to
property sustained by anyone in and about said Sublease Premises or any part
thereof, arising out of any way connected with Sublessee's use or occupation of
the Sublease Premises or this Sublease.

         9. ASSIGNMENT OR SUBLETTING. Sublessee shall not, without the prior
written consent of Sublessor, assign the term hereby demised, nor suffer or
permit it to be assigned by operation of law or otherwise, nor shall the
Sublessee, without the prior written consent of Sublessor, let or sublet or
permit the said Sublease Premises or any part thereof to be used by others for
hire.
