              Expenses (as defined in the Master Lease) that may become due
              during the Term. In the event that the Master Lease requires that
              payment of Taxes and Operating Expenses in installments, Sublessee
              shall pay such installments to Sublessor as and when they become
              due.

              as and when such charges may become due. Electricity for the

              when due, or if not separately metered, Sublessee shall pay to
              Sublessor the electric bill for the Sublease Premises, as
              reasonably determined by Sublessor.

                     (3)    Any sums due to Sublessor by Sublessee or due to GGP
              or Landlord by Sublessor under this Sublease, the GGP Sublease or

       6.     EXTENSION OPTION. If Sublessee desires to occupy and sublease the
entire "Sublease Premises" (as defined in the GGP Sublease), Sublessee shall
have the right to direct Sublessor to cause GGP to exercise the extension option
set forth in Paragraph 33 of the Master Lease upon the following terms and
conditions: (a) Sublessee shall deliver to Sublessor written notice of

described above in accordance with the terms of the Master Lease, but subject to
the provisions of clauses (b), (c) and (d) of this paragraph.

       7.     TERMINATION OPTION. If Sublessor intends to exercise the
"Termination Option" described in Paragraph 22 of the GGP Sublease and Paragraph
32 of the Master Lease, Sublessor shall provide to Sublessee at least fifteen
days' notice prior to any such exercise, and Sublessee
