Landlord shall permit Tenant and Tenant's Contractor access to the Premises prior to the Commencement Date for the performance of Tenant's Work if Tenant employs Landlord's Contractor or another contractor approved by Landlord for the performance of Tenant's Work and if the concurrent performance of the Base Building Improvements and Tenant's Work will not delay the Substantial Completion Date. Subject to the foregoing, Landlord shall cooperate with Tenant's Contractor in connection with Tenant's Work. If Tenant elects to have Landlord advance the Tenant Allowance, Tenant shall provide Landlord with a budget and copies of all contracts entered into with respect to Tenant's Work and such ether information as Landlord reasonably may request. The Tenant Allowance shall be advanced to Tenant by Landlord no more frequently than monthly against costs then incurred but unpaid by Tenant with respect to Tenant's Work. The Tenant Allowance shall be advanced to Tenant in the proportion which the Tenant Allowance bears to Tenant's budget, as the same may be updated, for Tenant's Work. Tenant shall make application to Landlord for an advance of the Tenant Allowance at least ten (10) business days prior to the date upon which an advance is to be made. Such application shall be on such form or forms as Landlord reasonably may require, and shall be accompanied by invoices, receipts, lien waivers and such other documents as Landlord reasonably may require.
