              similar economic incentives that may have been provided Tenant in

       B.     Except as herein modified or amended, the provisions, conditions

              and effect.

       C.     In the case of any inconsistency between the provisions of the

              govern and control.

       D.     Submission of this Amendment by Landlord is not an offer to enter
              into this Amendment but rather is a solicitation for such an offer
              by Tenant, Landlord shall not be bound by this Amendment until
              Landlord has executed and delivered the same to Tenant.

       E.     The capitalized terms used in this Amendment shall have the same
              definitions as set forth in the Lease to the extent that such
              capitalized terms are defined therein and not redefined in this
              Amendment.

       F.     With exception of Travers Realty, Tenant hereby represents to
              Landlord that Tenant has dealt with no broker in connection with

              members, principals, beneficiaries, partners, officers, directors,
              employees, mortgagee(s) and agents, and the respective principals
              and members of any such agents (collectively, the "LANDLORD
              RELATED PARTIES") harmless from all claims of any brokers claiming
              to have represented Tenant in connection with this Amendment.
              Landlord hereby represents to Tenant that Landlord has dealt with
              no broker, with exception of Travers Realty, in connection with
              this Amendment. Landlord agrees to indemnify and hold Tenant, its
              members, principals, beneficiaries, partners, officers, directors,
              employees, and agents, and the respective principals and members
              of any such agents (collectively, the "TENANT RELATED PARTIES")
              harmless from all claims of any brokers claiming to have
              represented Landlord in connection with this Amendment.

       G.     Each signatory of this Amendment represents hereby that he or she
              has the authority to execute and deliver the same on behalf of the
              party hereto for which such signatory is acting. Tenant hereby
              represents and warrants that neither Tenant, nor any persons or
              entities holding any legal or beneficial interest whatsoever in
              Tenant, are (i) the target of any sanctions program that is
              established by Executive Order of the President or published by
              the Office of Foreign Assets Control, U.S. Department of the
              Treasury ("OFAC"); (ii) designated by the President or OFAC
              pursuant to the Trading with the Enemy Act, 50 U.S.C. App. ss. 5,
              the International Emergency Economic Powers Act, 50 U.S.C. ss.ss.
              1701-06, the Patriot Act, Public Law 107-56, Executive Order 13224
              (September 23, 2001) or any Executive Order of the President
              issued pursuant to such statutes; or (iii) named on the following
              list that is published by OFAC: "List of Specially Designated
              Nationals and Blocked Persons." If the foregoing representation is
              untrue at any time during the Term, an [EVENT OF DEFAULT] under
              the Lease will be deemed to have occurred, without the necessity
              of notice to Tenant.

       H.     Redress for any claim against Landlord under the Lease and this
              Amendment shall be limited to and enforceable only against and to
              the extent of Landlord's interest in the Building. The obligations
              of Landlord under the Lease are not intended to and shall not be
              personally binding on, nor shall any resort be had to the private
              properties of, any of its trustees or board of directors and
              officers, as the case may be, its investment manager, the general
              partners thereof, or any beneficiaries, stockholders, employees,
              or agents of Landlord or the investment manager.
