respect to 21,014 rentable square feet (Demised Premises) on the first (1st) floor in the

hereof, for the entire Lease term, including all renewals and extensions, Landlord or Agent will debit monthly payments of Rent from the Account. Tenant acknowledges and agrees that the debits to the Account made or attempted to be made by Landlord
or Agent in no way lessen or alter Tenants obligations under the Lease, including, without limitation, those provisions regarding the amount of Rent, the amount of all adjustments to Rent, when payments are due, the application of payments and
the assessment of late payment charges and interest on delinquent rental payments. Tenant shall at all times be solely responsible for all fees, charges and expenses in any way related to (i) opening, maintaining and/or closing the Account or
(ii) any transfers in or from the Account. Tenant shall at all times maintain sufficient funds in the Account to cover the amount of each monthly debit to be made by Landlord or Agent under this Article. The failure to so maintain such funds

its Agent, is authorized to debit the Account monthly in accordance with and subject to the terms of this Article.

Tenant, reinstitute the automatic debiting of the Account in the same manner and subject to the same terms and conditions as are provided in this Article.
