claims, damages, losses, expenses (including reasonable attorneys' fees) and
liabilities incurred as a result of the non-performance, non-observance or

entitled to receive all services and repairs to be provided by Landlord to
Tenant under the Master Lease. Subtenant shall look solely to Landlord for all

Sublandlord to perform any of such services, nor shall Subtenant make any claim
upon Sublandlord for any damages which may arise by reason of Landlord's or
Tenant's default under the Master Lease or Sublease. Any condition resulting
from a default by Landlord or Tenant shall not constitute, as between
Sublandlord and Subtenant, an eviction, actual or constructive, of Subtenant and
no such default shall excuse Subtenant from the performance or observance of any
of its obligations to be performed or observed under this Sub-Sublease, or
entitle Subtenant to receive any reduction in or abatement of the Rent provided
for in this Sub-Sublease. In furtherance of the foregoing, Subtenant does hereby
waive any cause of action and any right to bring any action against Sublandlord
by reason of any act or omission of Landlord or Tenant under the Master Lease or
Sublease.

        10. Default by Subtenant. In the event Subtenant shall be in default of
any covenant of, or shall fail to honor any obligation under, this Sub-Sublease,
Sublandlord shall have available to it against Subtenant all of the remedies
available (a) to Landlord under the Master Lease in the event of a similar
default on the part of Tenant thereunder or (b) at law.

        11. Quiet Enjoyment. So long as Subtenant pays all of the Rent due
hereunder and performs all of Subtenant's other obligations hereunder,
Sublandlord shall do nothing to affect Subtenant's right to peaceably and
quietly have, hold and enjoy the Sublease Premises.

        12. Cure Periods; Notices.

Sublease to the contrary notwithstanding, Subtenant agrees to comply with and
remedy any default in this Sub-Sublease, the Sublease, or the Master Lease which
is Subtenant's obligation to cure, within the shorter of the period allowed to
Sublandlord under the Sublease or the Master Lease (as the case may be), even if
such time period is shorter than the period otherwise allowed therein due to the
fact that notice of default from Sublandlord to Subtenant is given after the
corresponding notice of default from Tenant to Sublandlord or Landlord to
Tenant.
