value of the premises which are the subject of the Lease for such unexpired
portion of the term of the Lease, taking into consideration the Lease as
modified, if such is the case, or (ii) if the Lease is terminated or rejected,
execute and deliver to Landlord, or their successors or assigns, a new lease

interest on the amounts which become payable and are designated in (a) and
(b)(i) above at 18% per annum from the date of such termination, rejection or
modification to the date of payment, including any period of time after any

            Neither the obligation of the undersigned to make payment in
accordance with the terms of the Guaranty nor any remedy for the enforcement

whatsoever by any impairment, modification, change, release or limitation of the
liability to the Tenant, or its estate in bankruptcy, or otherwise, or of any
remedy for the enforcement thereof, resulting from the operation of any present
of future provision of the Federal Bankruptcy Code, or of any other statute, or
from the decision of any Court.

            Landlord may, without notice to or demand upon the undersigned and

security for the obligations under this Guaranty and the Lease, add to, exchange
or release any such security, apply or realize upon such security as Landlord
determines and release, add or substitute any one or more guarantors should more
than one person or entity be or become liable on this Guaranty. Landlord may
exercise any right or remedy it may have against Tenant or any security held by
Landlord without impairing the obligations of the undersigned on this Guaranty,
and the undersigned waives any defense arising out of the absence, impairment or
loss of any right of reimbursement, subrogation or other remedy of the
undersigned against Tenant or any such security, whether resulting from any
election by Landlord or otherwise.

            The undersigned assumes the responsibility to keep informed of the
financial condition of Tenant under the Lease and all other circumstances
bearing upon the risk of non-payment or non-performance by Tenant under the
Lease, and agrees that, absent a request for such information by the
undersigned, Landlord shall have no duty to advise the undersigned of
