     3.   (a)  (i)  Tenant acknowledges that it has inspected the Expansion
          Space, and agrees that it takes the Expansion Space in its AS-IS
          condition, and that, except as hereinafter specifically provided,
          Landlord has no obligation to make any improvements to the Expansion

          All work performed by any Tenant contractor shall be done in a good
          and workmanlike manner, meet all appropriate building codes and
          regulations and be diligently prosecuted to completion. Tenant agrees
          to indemnify and hold Landlord harmless from any loss and/or damage
          that Landlord may sustain arising out of or resulting from Tenant's
          contractors' deficiency in work and materials. If Tenant shall obtain
          access to the Expansion Space for such purposes, it must, prior to

          Twelve Thousand, Forty-Six and 56/100 Dollars ($12,046.56); and

          (iv) from and after 12:01 a.m. on December 1, 2003 to and including

          Amendment, Tenant shall deposit with Landlord the additional sum of
          Eleven Thousand, Three Hundred Fifty-Five and 04/100 Dollars
          ($11,355.04), which shall be added to and become part of "Tenant's
          Security Deposit" (as said term is defined in the Original Lease).

     7.   Effective as of the Expansion Space Commencement Date, Section 1.01(L)
          of the Lease shall be deemed amended to reflect that "Tenant's Share"

          notwithstanding the provisions of Section 7.01(e) of the Original
          Lease to the contrary, Tenant desires to take advantage of the
          Lock-Out System, Landlord shall provide Tenant with such number of
          elevator security keys to permit access to the ninth floor of the
          Building as may be requested by Tenant, provided that Tenant shall pay
          to Landlord, as Additional Rent (i) Twenty Dollars ($20.00) per
          elevator security key requested by Tenant, and (ii) an additional sum
          of Two Hundred Fifty Dollars ($250.00) per calendar year during any
          calendar year in which, at Tenant's request, elevator access to the
          ninth floor of the Building controlled, as aforesaid.
