23. NOTICES

23.1 Any notice, demand or other communication (each, a “notice”) that is given or rendered pursuant to this Lease by either Landlord or Tenant to the other party, shall be (i) given or rendered, in writing, (ii) addressed to the other party at its required address(es) for notices delivered to it as set forth in Section 23.2 below, and (iii) delivered via either (x) hand delivery, (y) nationally recognized courier service (e.g., DHL, Federal Express, Express Mail) or (z) certified U.S. mail postage prepaid with return receipt requested. Any such notice shall be deemed given or rendered, and effective for purposes of this Lease, as of the date actually delivered to the other party at such address(es) (whether or not the same is then received by other party due to a change of address of which no notice was given, or any rejection or refusal to accept delivery). Notices from either party (to the other) may be given or rendered by its counsel.

23.2 The required address of each party for notices delivered to it are as set forth below. Each party, however, may, from time to time, designate an additional or substitute required address(es) for notices delivered to it (provided, that such designation must be made by notice given in accordance with this Section 23).

24. QUIET ENJOYMENT. Landlord hereby covenants and agrees that, unless and until an Event of Default shall occur, Tenant shall, at all times during the Term, have peaceable and quiet enjoyment and possession of the Premises without any manner of hindrance from Landlord or any other person, firm or corporation.

25. ESTOPPEL CERTIFICATE. Within ten (10) days after a written notice from Landlord, Tenant shall execute and deliver to Landlord a statement certifying (a) that this Lease is in full force and effect, (b) that this Lease has not been amended, or if so amended, specifying the date of each amendment, (c) the date to which Basic Rent has been paid, (d) stating whether or not Tenant has delivered to Landlord any notice that indicates that Landlord is in default in performance of any of its obligations under this Lease, which notice remains outstanding (and, if so, specifying each such notice and default), and (e) stating whether or not Tenant has received from Landlord any notice that alleges that Tenant is in default in performance of any of its obligations under this Lease, which notice remains outstanding (and, if so, specifying each such notice and alleged default). At Landlord’s request, the aforementioned certification shall be to Landlord’s Mortgagee or other lender or Landlord’s purchaser or investor, as well as Landlord. Tenant’s failure to deliver such statement within ten (10) days after a second written notice requesting such statement, which second notice is given by Landlord after expiration of the ten (10) day period described above, shall conclusively be deemed to be an admission by Tenant of the matters set forth in the request for an estoppel certificate.
