The Tenant Improvement Allowance will be disbursed in accordance with Landlord's standard disbursement procedures, including, without limitation, following Landlord's receipt of (i) evidence (i.e., invoices or other documentation reasonably satisfactory to Landlord) of payment for the Tenant Improvements, or portions thereof, paid for with the Tenant Improvement Allowance, and (ii) fully executed, unconditional lien releases from all contractors, subcontractors, laborers, materialmen, and suppliers used by Tenant in connection with the Tenant Improvements paid for with the Tenant Improvement Allowance. The Tenant Improvements shall be constructed in accordance with the terms and conditions of Article 8 of the Original Lease. In no event shall Landlord be obligated to disburse any portion of the Tenant Improvement Allowance subsequent to the date which is twelve (12) months following the Delivery Date, nor shall Landlord be obligated to disburse any amount in excess of the Tenant Improvement Allowance in connection with the construction of the Tenant Improvements. No portion of the Tenant Improvement Allowance, if any, remaining after the construction of the Tenant Improvements shall be available for use by Tenant.

Tenant shall construct improvements to the Premises (the “Tenant Improvements”) in substantial conformity with the plans and outline specifications of the plan to be prepared pursuant to the provisions of the Work Letter (the “Work Letter”) attached hereto as Exhibit B. Landlord shall provide Tenant with a one-time tenant improvement allowance in the amount of $100.00 per rentable square foot of the Expansion Premises (i.e. $1,208,500.00) (the “Expansion Premises Allowance”) and $30.00 per rentable square foot of the Existing Premises (i.e. $571,080) (the “Existing Premises Allowance” and, together with the Expansion Premises Allowance, the “Tenant Improvement Allowance”) for the costs relating to the Tenant Improvements. The Expansion Premises Allowance shall only be used for the costs relating to the Tenant Improvements in the Expansion Premises. The Existing Premises Allowance may be used for the costs relating to the Tenant Improvements in the Existing Premises and/or the Expansion Premises, in Tenant’s sole discretion. In no event shall Landlord be obligated to contribute toward the cost of the Tenant Improvements which are not agreed upon by Landlord or a total amount which exceeds the Tenant Improvement Allowance. Any portion of the Tenant Improvement Allowance which has not been expended and requested from Landlord pursuant to the terms of Section 2 of the Work Letter by April 30, 2020 shall be forfeited. Subject to Section 5(b) below, Tenant shall be responsible for any costs incurred to make the Existing Premises compliant under any applicable codes or Applicable Laws, as a result of the Tenant Improvements and Landlord shall be responsible for any costs incurred to make the Building (except for the Existing Premises) compliant under any applicable codes or Applicable Laws, as a result of the Tenant Improvements.

$1,227,980.00 (i.e., approximately $20.00 per rentable square foot of the Existing Premises only) for the costs relating to the initial design and construction of Tenant's improvements which are permanently affixed to the Existing Premises only (the “Tenant Improvements”). The Tenant Improvement Allowance will be disbursed in accordance with [Section 2.2.2] of the Tenant Work Letter attached as Exhibit B to the Second Amendment. The Tenant Improvements shall be constructed in accordance with the terms and conditions of Article 8 of the Original Lease. In no event shall Landlord be obligated to disburse any portion of the Tenant Improvement Allowance subsequent to December 31, 2022 (the “Outside TI Date”), nor shall Landlord be obligated to disburse any amount in excess of the Tenant Improvement Allowance in connection with the construction of the Tenant Improvements. No portion of the Tenant Improvement Allowance, if any, remaining after the Outside TI Date shall be available for use by Tenant.

Tenant Improvements Allowance. So long as Tenant is not in default, Tenant shall be entitled to an one-time tenant improvements allowance (the “Tenant Improvements Allowance”) in the maximum aggregate amount of: # $898,645.00 for the Expansion Premises (i.e., $55.00 per rentable square foot of the Expansion Premises) (the “Maximum Allowance Amount”) for the hard costs and customary soft costs, as noted below, incurred by Tenant including, without limitation out-of-pocket architectural and engineering fees, construction contractor fees, Tenant’s project management fees, and a two percent (2%) project management fee payable to Landlord or its affiliates (“Landlord’s Project Oversight Fee”), and permits, and such other costs arising from or relating to the design and construction of Tenant’s improvements which are to be permanently affixed to the Expansion Premises in accordance with this Work Letter (the “Tenant Improvements”). Landlord’s Project Oversight Fee shall be equivolent to, but not exceed, a total of 2% of the Tenant Improvement Allowance paid to Tenant. In no event shall Tenant be permitted to use any excess Tenant Improvements Allowance toward the Base Rent or any soft costs that are not directly related to the design and construction within the Expansion Premises. For the avoidance of any doubt, the purchase and installation of data and telecommunications cabling shall not be included in the definition of Tenant Improvements and there shall not be any Landlord’s Project Oversight Fee payable with respect to costs and expenses related thereto. The Tenant agrees to keep the Landlord advised as to the progress of the work by providing copies of the Contractor’s applications for payment. In no event shall Landlord be obligated to make disbursements pursuant to this Tenant Work Letter in a total amount which exceeds the Maximum Allowance Amount and in no event shall Tenant be entitled to any credit for any unused portion of the Tenant Improvements Allowance. All Tenant Improvements for which the Tenant Improvements Allowance has been made available shall be deemed Landlord’s property under the terms of the Lease.
