If the determination of at least two of the arbitrators shall be identical in amount, said amount shall be the fair market rental value. If the determinations of at least two of the arbitrators shall not be identical in amount, the fair market rental value, shall be determined as follows: (a) if neither the highest nor the lowest determination differs from the middle determination by more than ten percent (10%) of such middle determination, then the fair market rental value shall be the average of all three determination, and (b) , if clause (a) does not apply, then the fair market rental value shall be the average of the middle determination and the determination closest in amount to said middle determination. Landlord and Tenant shall split the cost of determining the fair market value of the Premises.

Tenant hereby assigns to Landlord all Tenant's rights, title and interest in and to any and all amounts awarded or paid by reason of such appropriation, condemnation or taking, provided, however, that none of the foregoing is meant to deprive the Tenant from claiming moving expenses, displacement expenses or the like solely from the acquiring authority. 11.
