Cost Proposal After the Approved Working Drawings are approved by Landlord and Tenant, Landlord shall provide Tenant with a cost proposal in accordance with the Approved Working Drawings, which cost proposal shall include, as nearly as possible, the cost of all TI Allowance Items to be incurred by Tenant in connection with the construction of the Tenant Improvements (the "Cost Proposal"). Landlord does not guaranty the accuracy of the Cost Proposal. Notwithstanding the foregoing, portions of the cost of the Tenant Improvements may be delivered to Tenant as such portions of the Tenant Improvements are priced by Contractor (on an individual item-by-item or trade-by-trade basis), even before the Approved Working Drawings are completed (the "Partial Cost Proposal"). Tenant shall either (i) approve and deliver the Cost Proposal to Landlord within five (5) business days of the receipt of the same (or, as to a Partial Cost Proposal, within two (2) business days of receipt of the same), or (ii) notify Landlord within five (5) business days after Tenant's receipt of the Cost Proposal (or Partial Cost Proposal, as the case may be) that Tenant desires to revise the Approved Working Drawings to reduce the amount of the Cost Proposal (or Partial Cost Proposal, as the case may be), in which case such changes shall be made to the Approved Working Drawings only in accordance with Section 2.7 above and the revised Working Drawings shall be provided to the Contractor for repricing whereupon Landlord shall revise the Cost Proposal (or Partial Cost Proposal, as the case may be) for Tenant's approval. This procedure shall be repeated until the Cost Proposal (or Partial Cost Proposal, as the case may be) is approved by Tenant. The date by which Tenant has approved the Cost Proposal, or the last Partial Cost Proposal, as the case may be, shall be known hereafter as the "Cost Proposal Delivery Date." The total of all Partial Cost Proposals, if any, shall be known as the Cost Proposal.
