June 30th, 2005, Landlord agrees to pay $39,762.10 for every month or partial month of delay, starting July 1st, 2005. Notwithstanding anything contained to
the contrary, Landlord shall not be responsible for the penalty if the delays are the result of written requested change or upgrades of the floor plan initiated by Tenant including delays in Tenant's

2.     Renewal
Rights. Tenant has two (2) options-to-renew the term of this lease for up to two (2) years each at 100% of a

3.     Expansion
Rights. Tenant has an ongoing Right-of-First-Refusal on any space on the Fourth Floor that is available or becomes available during the
Term. Tenant shall have ten (10) business days from receipt of Landlord's notice to exercise its Right-of-First-Refusal. Term for the expansion area shall be coterminous
and shall commence when Landlord substantially completes any improvements. Terms and conditions shall be identical to Tenant's original lease with all concessions and allowances prorated over the

to the commencement date of the applicable renewal term. The net fair market rental value to be determined shall not take into account any existing tenant improvements or any special uses or rights
afforded to the tenant under the lease in connection with the premises, but shall take into account the following factors:
