extend this lease for five (5) years each, on the same terms and conditions as

the end of each five (5) year term. TIME IS OF THE ESSENCE IN REGARD TO THE
DELIVERY OF THE NOTICE. In the event Tenant fails to deliver written notice as
herein provided, the options granted herein shall expire and be of no further
force or effect.

"Landlord") from and against any and all loss, cost, action liability, damage or
expense, including but not limited to, penalties, fines, attorneys' fees or
costs (collectively "claims"), to any person, property or entity resulting from
the following: (i) the negligence or wilful misconduct of Tenant, its agents,
employees or contractors; (ii) Tenant's default or breach of any of the terms
and conditions of this Lease; and (iii) any occurrences within the Premises, not
resulting from the negligence or wilful misconduct of Landlord, its agents,
employees or contractors.

           Landlord agrees to defend with counsel reasonably satisfactory to

<PAGE>
liability, damage or expense, including but not limited to, penalties, fines,
attorneys' fees or costs (collectively "claims"), to any person, property or
entity resulting from the following: (i) the negligence or wilful misconduct of
Landlord, its agents, employees or contractors; (ii) Landlord's default or
breach of any of the terms and conditions of this Lease; and (iii) any
occurrences within the Premises, not resulting from the negligence or wilful
misconduct of Tenant its agents, employees or contractors.

     Notwithstanding the foregoing, however, because Landlord is required to
maintain property insurance on the Building, and because of the existence of
waivers of subrogation set forth in this Lease, Landlord hereby agrees to
defend, indemnify and hold Tenant harmless on any Claims to the extent such
claim is covered by such insurance, even if resulting from the negligent acts,
omissions or misconduct of Tenant or those of its agents, employees or
contractors. Similarly, since Tenant must carry insurance to cover its personal
property within the premises, and because of the waivers of subrogation set
forth in this Lease, Tenant hereby agrees to defend, indemnify and hold Landlord
harmless from any claims to the extent any such claim is covered by such
insurance, if resulting from the negligent acts, omissions or misconduct of
Landlord or those of its agents, employees or contractors. The provisions of
this section shall survive the expiration or sooner termination of the Lease
with respect to any occurrences, claims or liabilities occurring prior to such
expiration or termination.
