Section 31.2.For Extension Term No. 4 Basic Annual Rent shall be calculated at fair market value for comparable buildings in the Raritan, NJ area, as mutually agreed upon by Tenant and Landlord. In the absence of such agreement within sixty (60) days after Tenant’s exercise of said option, the fair market rental rate for the extended term shall be determined within the following thirty (30) days by an independent, reputable third party appraiser chosen by Landlord, subject to the Tenant’s reasonable approval, who shall have at least ten (10) years experience in the commercial real estate market in the area in which the building is located.  The Tenant may rescind its exercise of the extension option by so notifying the Landlord within five (5) business days after receiving the appraiser’s determination of fair market rent. Time is of the essence of this Lease, including, without limitation, this Section.

5.Notwithstanding any other provision of this Lease, Tenant shall have the right to terminate this Lease at any time after the execution date of this Amendment on the following terms:

(a)such termination shall be effective as of the 180^th day after the date on which Tenant notifies Landlord in writing of Tenant’s election to so terminate; and

(b)Tenant shall pay to Landlord all amounts due and payable under this Lease up to said effective date, and, as a Termination Fee, an amount equal to the lesser of (i) 50% of the total amount of the Basic Annual Rent payable under this Lease for the period from the effective date of termination until February 28, 2013, or (ii) one year’s Basic Annual Rent calculated by taking the sum of Basic Monthly Rental payments that would have been due from Tenant for the twelve (12) months beginning on the first day of the month after the month in which the effective date of termination occurs. Such Termination Fee shall be due and payable no later than ten (10) days prior to the effective date of termination.

6.The provisions of the Original Lease as modified by this Amendment No. 4 are applicable during Extension Term No. 3. Except as specifically amended hereby, the Lease remains in full force and effect.

EXECUTED as a sealed instrument as of the date first written above.
