agreements herein contained, and in consideration of other good and valuable
consideration, each to the other, the sufficiency and receipt of which are
hereby acknowledged, the parties hereto agree, covenant, and warrant as follows:

amendment specified herein or subsequently approved by Landlord on the part of
Subtenant to be observed and performed, in the event the Lease is terminated due

amendments specified herein or hereafter approved by Landlord will continue in

Landlord shall recognize the Sublease and any modifications or amendments
specified herein or subsequently approved by Landlord and Subtenant's rights
thereunder, and will thereby establish direct privity of estate and contract
between Landlord and Subtenant with the same force and effect and with the same
relative priority in time and right as though the Sublease and any modification
or amendment specified herein or subsequently approved by Landlord were directly
made from Landlord in favor of Subtenant; provided, however, that
notwithstanding anything in this Agreement to the contrary, in the event of a
termination of the Sublease and the recognition of the Sublease as set forth
herein, the terms of Section 14 of the Sublease have no applicability as between
Landlord and Subtenant.

     2. Subtenant agrees that in the event of any act or omission by Tenant
under the Sublease which would give Subtenant the right, either immediately or
after a period of time, to terminate the Sublease, whether or not set forth in

Landlord as substitute sublessor upon the same terms, covenants and conditions

establish direct privity of estate and contract between the Landlord and
Subtenant with the same force and effect as though the Sublease and all
modifications and amendments thereof specified herein or hereafter consented to
by Landlord, together with all guarantees of Subtenant's obligations under the
Sublease, were originally made directly between Landlord and Subtenant (except
as specifically set forth in this Agreement). Subtenant will thereafter make all
payments directly to Landlord. Subtenant waives all joinder and/or service of

building in which the Subleased Premises are located and no recourse shall be
had to any other assets of Landlord.

          (d) It is specifically agreed that Subtenant shall not, as to
Landlord, require cure of any such default which is personal to Tenant, its
successors or assigns, and therefore not susceptible of cure by Landlord.

after the termination of the Lease by Landlord, Subtenant (as tenant) agrees to
execute a lease of the Sublease Premises with Landlord or its successor (as
