"Lease Year" means the one-year period beginning on the Rent Commencement Date and each anniversary of the Rent Commencement Date; however, if the Rent Commencement Date is a date other than the first day of the month, then each Lease Year will begin on the first day of the month following the Rent Commencement Date. Rent and any other sums provided in this Lease for which the Lease Year is a factor shall be adjusted and paid on pro rata basis for any partial month prior to the first Lease Year. "Lease Month" means a calendar month beginning on the Rent Commencement Date and at the beginning of each calendar month thereafter; however, if the Rent Commencement Date is a date other than the first day ofthe month, then the first Lease Month will begin on the first day ofthe month following the Rent Commencement Date. 2.2 In the event that Tenant fails to vacate the Leased Premises at the end ofthe Term of this Lease (defined below), or sooner in the event that this Lease is terminated earlier pursuant to the provisions hereof, Tenant acknowledges that such holdover as a month-to-month tenant is no1 desirable to Landlord and that the Base Rent should be reflective ofthat undesirability.

Therefore, ifTenant holds over after the expiration of the Term of this Lease or any exercised option term with or without objection from Landlord, then such holding over will not extend the Term of this Lease, but will create a month-to-month tenancy under the same conditions as this Lease except that Base Rent shall be paid in the amount ofone hundred twenty-five percent (12506) of the Base Rent set forth in Section 4.1 hereof and the Additional Rent (defined below) then being paid by Tenant to Landlord for the month immediately prior to the holdover period.

The payment of such increased Rent shall not limit the damages to which Landlord is entitled hereunder. ARTICLE III .

Department ofLabor (the "CPI") on the first day ofthe then current Lease Year, and the denominator of which is the CPI on the previous lease year. In no event shall the Base Rent go down in any Lease Year from the previous Lease Year. 4.2 All Rent is payable in advance, without demand, in fixed monthly installments of one twelfth (1/l2th) ofthe then-current annual Base Rent on or before the fifteenth (l5th) day of each and every month prior to the month for which the Rent is being paid during the Term hereof.

The service charge lor a late payment shall be an amount equal to ten percent (10%) of any installment of Rent and other charges past due for more than five (5) business days; provided, however, interest on such past due installment and late payment charge shall accrue at the rate of eighteen percent (18%) per annum after the thirtieth (30th) day such installment is past due until paid.

Therefore, none of the terms ofthis Lease shall ever be construed to create a contract to pay interest at a rate in excess ofthe Maximum Rate, and Tenant shall not be liable for interest in excess of that determined at the Maximum Rate, and the provisions of this Section shall control all other provisions of this Lease. Ifany amount of interest taken or received by Landlord shall be in excess ofthe Maximum Rate, then the excess shall be deemed to have been the result ofa mathematical error by Landlord and Tenant and shall be applied by Landlord to Tenant's next installment ofBase Rent or other charges owed by Tenant to Landlord or, if this Lease Agreement has terminated and no amounts are due to Landlord" shall be refunded promptly to Tenant.
