The term "Market Rent" shall mean the rent being charged for comparable existing space at the time the extension option is exercised, as reasonably determined by the Lessor. Lessor shall send a written notice to Lessee specifying the rent for the extension term within thirty (30) days of its receipt of Lessee's exercise of option to extend. Lessee shall be deemed to have rejected the new rent level if it has not sent Lessor a notice approving the same within ten (10) days of receipt of Lessor s notice. In the event Lessee disapproves the new rent level, then Market Rent shall be determined as follows: Each party shall within ten (10) days of Lessee's disapproval appoint an arbitrator to act on its behalf, which person shall be a real estate broker or other person experienced in the appraisal or management of real estate within the Nashua metropolitan area. If the two arbitrators are unable to reach agreement within ten (10) days after their appointment, then the two arbitrators shall appoint a third arbitrator and the decision by a majority of the arbitrators shall be binding upon the parties. Each party shall each bear the cost of the arbitrators selected by it and shall jointly bear the cost of any third arbitrator. In the event the arbitrators have failed to establish "Market Rent" by the commencement of the Extension Term, Lessee shall pay at the rental rate proposed by Lessor in its notice to Lessee, with a prompt adjustment between the parties retroactive to the commencement date of the Extension Term in the event such arbitration results in a reduction of the rental rate. Under no circumstances shall the Base Rent during the Extension Term be less than the Base Rent in effect during the last year of the Term. IN WITNESS WHEREOF, the parties have caused this Lease to be executed by their respective authorized representatives the day and year first written above. LESSOR: MARELD COMPANY, INC.
