C. Landlord and Tenant have discussed an extension of the term of the Lease and an adjustment in the rental rates in conjunction with such extension, and have reached agreement on modifications to the Lease, as set forth below. 1 NOW, THEREFORE, for mutual consideration, the receipt and adequacy of which is hereby acknowledged, Landlord and Tenant hereby amend the Lease as follows: 1.
