Each Ground Lease (as modified by the applicable Ground Lease Estoppel Certificate provided by the landlord thereunder) requires the ground lessor to give notice of any default by Borrowers to Administrative Agent. Each Ground Lease, or the applicable Ground Lease Estoppel Certificate, further provides that notice of termination given under such Ground Lease is not effective against Administrative Agent unless a copy of the notice has been delivered to Administrative Agent in the manner described in such Ground Lease.
