II.      Effective Date. This Amendment shall become effective as of the date

III.     Miscellaneous.

         A.       This Amendment sets forth the entire agreement between the
                  parties with respect to the matters set forth herein. There
                  have been no additional oral or written representations or
                  agreements. Under no circumstances shall Tenant be entitled to
                  any Rent abatement, improvement allowance, leasehold
                  improvements, or other work to the Premises, or any similar

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

                  shall 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.       Tenant hereby represents to Landlord that Tenant has dealt
                  with no broker in connection with this Amendment. Tenant
                  agrees to indemnify and hold Landlord, its 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 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.

         IN WITNESS WHEREOF, Landlord and Tenant have duly executed this
Amendment as of the day and year first above written.
