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.
