D) Rent Abatement: Rent for the first month of the Lease Extension shall be abated for the Relocation Premises.

G) Tenant Improvements. LANDLORD shall deliver the Relocation Premises to TENANT in as-is, ADA-compliant, condition, with the following Tenant Improvements to be completed at LANDLORD’S sole cost and expense:

H) Security Deposit: TENANT has previously deposited with LANDLORD the sum of fifteen thousand seven hundred thirty-eight & 42/100 dollars ($15,738.42), equal to one month’s Base Rent for the Initial Premises, as a security for the payment and performance by TENANT of all of TENANT’S obligations, covenants, conditions, and agreements under the Lease for the Initial Premises.

Upon the expiration of the Term (or any renewal or extension thereof in accordance with this Lease), LANDLORD shall, provided that TENANT is not in default under the Terms hereof, return and pay back such security deposit to TENANT, less such portion thereof as LANDLORD shall have appropriated to cure any default by TENANT with respect to any of TENANT’S aforesaid obligations, covenants, conditions, and agreements. In the event of any material default by TENANT hereunder, LANDLORD shall have the right, but shall not be obligated to, apply all or any portion of the security deposit to cure such default, in which event TENANT shall be obligated promptly to deposit with LANDLORD the amount necessary to restore the security deposit to its original amount. In the event of the sale or transfer of LANDLORD’S interest in the Building,

LANDLORD shall have the right to transfer the security deposit to such purchaser or transferee in which event TENANT shall look only to the new Landlord for the return of the security deposit and LANDLORD shall thereupon be released from all liability to TENANT for the return of such security deposit.

TENANT may exercise this option by giving LANDLORD written notice on or before the date nine (9) months prior to the expiration date of the then current Extension Term and thereafter the term of this Lease shall be deemed extended upon the terms and conditions of this Lease except that the Base Rent for such extended term shall be the fair market rental as reasonably determined by the Three Broker Method (in which LANDLORD and TENANT each select a broker, those brokers select a third broker, and the fair market valuations of each are averaged) is used. If TENANT fails to give timely notice, time being of the essence, TENANT shall have no further rights to extend.
