(iii) Section 1(g) of the Lease is amended to provide that, effective July 1, 2005, the annual Base Rental for the Demised Premises will be $922,449.78 ($76,870.82 per month), which has been computed by taking the current annual Base Rental ($965,873.78) and subtracting the annual rental for Suite 145, computed as follows: $965,873.78 - $43,424 (2,714 x $16/square foot) = $922,449.78.

If the parties are unable to mutually agree upon the selection of a qualified appraiser, then each party shall select a qualified appraiser at their own expense, and such appraisers shall thereafter select a third appraiser. The third appraiser will then be engaged to determine the prevailing market rental for the Demised Premises, which amount will be used as the Base Rental during the Option Term; provided, however, in no event shall the Base Rental during the Option Term be less than the Base Rental during the last year of the term of the Lease. The cost of the appraisal shall be paid equally by the parties. 4. Tenant Allowance - Suite 200.

For purposes of the Allowance, Landlord will complete such improvements to Suite 200 as Tenant reasonably requests, up to a maximum cost of $30,000. Based upon information supplied by Tenant to Landlord with respect to the proposed improvements, Landlord will prepare appropriate plans and specifications for the improvements, a cost estimate, and a construction timeline, all of which shall be submitted to Tenant for its review and reasonable approval. Landlord will thereafter complete the leasehold improvements in accordance plans and construction timeline agreed upon by the parties. 5. Capitalized terms, if not defined in this Amendment, shall have the meanings set forth in the Lease. Except as otherwise modified by this Amendment, the remainder of the Lease is hereby ratified and confirmed.
