the Lease may, at Landlord's option, be furnished from time to time, in whole or

pay more money on account of its occupancy of the Premises under the terms of
the Lease, and provided further that no such contract shall result in Tenant
having greater obligations or receiving less services than it is presently
obligated for or entitled to receive under the Lease or, services of a lesser
