1. Section 5 of Exhibit C to the Lease is hereby deleted in its entirety and replaced with the following:

“Provided Tenant is not in Default, following the date that Tenant has provided to Landlord written evidence that Tenant has completed and paid for at least Eight Hundred Thirty-Five Thousand and 00/100 Dollars ($835,000.00) of Tenant Improvements in and to the Premises, including submission to Landlord of partial lien waivers relating thereto, Landlord shall reimburse to Tenant (or pay directly to Tenant’s general contractor) the Improvement Costs (as hereinafter defined) incurred in constructing the Tenant Improvements, an amount equal to up to the Allowance (as defined in Section 1.7 above), in accordance with the following. For purposes of satisfying the foregoing, Tenant must have made at least Eight Hundred Thirty-Five Thousand and 00/100 Dollars ($835,000.00) of Tenant Improvements spent toward hard construction costs or toward architectural, engineering or permitting fees associated with the Premises.

Landlord shall fund the first (1^st) thirty percent (30%) of the Allowance within forty-five (45) days following Tenant’s submission to Landlord of: (i) a written certification from Tenant’s general contractor that the Tenant Improvements are at least fifty percent (50%) complete; and (ii) partial lien waivers relating to the first fifty percent (50%) of the Tenant Improvements;

Landlord shall fund the next thirty-five percent (35%) of the Allowance within forty-five (45) days following Tenant’s submission to Landlord of: (i) a written certification from Tenant’s general contractor that the Tenant Improvements are at least seventy-five percent (75%) complete; and (ii) partial lien waivers relating to the first seventy-five percent (75%) of the Tenant Improvements Landlord shall pay the balance of the Allowance within forty-five (45) days following the date that Tenant’s contractor has:

(ii) delivered to Landlord lien waivers and affidavits from Tenant’s contractor, all subcontractors, and all laborers or materials suppliers having performed any work at the Premises relating to the Tenant Improvements, together with any other evidence reasonably required by Landlord to satisfy Landlord’s title insurer that there are no parties entitled to file a lien against the real property underlying the Park in connection with such work; and

3. All capitalized but undefined terms used herein shall have the same meaning as set forth in the Lease.
