Estoppel. Owner and Developer each hereby acknowledges and agrees that, as of the Effective Date of this Amendment, the Development Agreement is in full force and effect and, to the best of its actual knowledge, no defaults, or events of Force Majeure Delay or Owner Delay, have occurred (or with the giving of notice and expiration of applicable cure periods would be deemed to have occurred) under the Development Agreement.

Estoppel. To induce Agent to enter into this Amendment and to continue to make advances to Borrower under the Credit Agreement, Borrower hereby acknowledges and agrees that, immediately before and after giving effect to this Amendment, as of the date hereof, there exists no Default or Event of Default and no right of offset, defense, counterclaim or objection in favor of Borrower or any Guarantor as against Agent or any Lender with respect to the Obligations.

Estoppel Certificate. Tenant shall, within ten (10) business days after receipt of written notice from Landlord, execute, acknowledge and deliver a statement in writing substantially in the form attached to this Lease as [Exhibit H], or on any other commercially reasonable form requested by a current or proposed Lender or encumbrancer or proposed purchaser, # certifying that this Lease is unmodified and in full force and effect (or, if modified, stating the nature of such modification and certifying that this Lease as so modified is in full force and effect) and the dates to which rental and other charges are paid in advance, if any, # acknowledging that there are not, to Tenant’s knowledge, any uncured defaults on the part of Landlord hereunder, or specifying such defaults if any are claimed, and # setting forth such further information with respect to this Lease or the Premises as may be reasonably requested thereon. Any such statements may be relied upon by any prospective purchaser or encumbrancer of all or any portion of the Property. If Tenant fails to timely deliver such statement within the prescribed time, Landlord shall send a second notice and if Tenant fails to respond to such second notice (by delivery of a signed estoppel) within three (3) business days, Tenant’s failure to timely deliver such statement shall, at Landlord’s option, constitute a Default (as defined below) under this Lease, and, in any event, shall be binding upon Tenant that the Lease is in full force and effect and without modification except as may be represented by Landlord in any certificate prepared by Landlord and delivered to Tenant for execution. Within ten (10) business days of receipt of a written request by Tenant, Landlord shall provide Tenant with a similar commercially reasonable estoppel certificate (but in all cases limited to Landlord’s actual knowledge (without any duty of inquiry or investigation)) as Landlord reasonably deems appropriate and as otherwise reasonably modified by Landlord.

ESTOPPEL CERTIFICATES. Within ten (10) business days following a request in writing by Landlord, Tenant shall execute, acknowledge and deliver to Landlord an estoppel certificate, which, as submitted by Landlord, shall be substantially in the form of Exhibit D, attached hereto (or such other form as may be reasonably required by any prospective mortgagee or purchaser of the Project, or any portion thereof), indicating therein any exceptions thereto that may exist at that time, and shall also contain any other information reasonably requested by Landlord or Landlord's mortgagee or prospective mortgagee. Any such certificate may be relied upon by any prospective mortgagee or purchaser of all or any portion of the Project. Tenant shall execute and deliver whatever other instruments may be reasonably required for such purposes. At any time during the Lease Term, in connection with a sale or financing of the Building by Landlord, Landlord may require Tenant to provide Landlord with its most recent annual financial statement and annual financial statements of the preceding two (2) years, subject to the terms below. Such statements shall be prepared in accordance with generally accepted accounting principles and, if such is the normal practice of Tenant, shall be audited by an independent certified public accountant. Landlord shall hold such statements confidential. Notwithstanding the foregoing, in the event that # stock in the entity which constitutes Tenant under this Lease (as opposed to an entity that controls Tenant or is otherwise an affiliate of Tenant) is publicly traded on NASDAQ or a national stock exchange, and # Tenant has its own, separate and distinct [[Unknown Identifier]] and [[Unknown Identifier]] filing requirements (as opposed to joint or cumulative filings with an entity that controls Tenant or with entities which are otherwise affiliates of Tenant), then Tenant's obligation to provide Landlord with a copy of financial statements shall be deemed satisfied. Failure of Tenant to timely execute, acknowledge and deliver such estoppel certificate or other instruments shall constitute an acceptance of the Premises and an acknowledgment by Tenant that statements included in the estoppel certificate are true and correct, without exception.

After written request by ​, which request following a Securitization shall, provided no Event of Default then exists, not be made more than twice each calendar year, ​ shall within ten (10) Business Days furnish ​ with a statement, duly acknowledged and certified, setting forth # the original principal amount of the Loan, # the unpaid principal amount of the Loan, # the Interest Rate of the Loan, # the date installments of interest and/or principal were last paid, # any offsets or defenses to the payment of the Debt and/or any claims against ​ then known to ​, if any, # that the Note, this Agreement, the Mortgage and the other Loan Documents are valid, legal and binding obligations and have not been modified or if modified, giving particulars of such modification, and # whether, to ​’s knowledge, there is any Default or Event of Default then continuing.
