If an Event of Default specified in Section 8.1(e) or (f) above occurs relating to the Borrower or its Subsidiaries, all principal and accrued and unpaid interest thereon will be immediately due and payable on the Note without any declaration or other act on the part of the Indenture Trustee or the Lender.

Lender shall not, however, be under any obligation to marshall any assets in favor of Borrower or against or in payment of any or all obligations under any Loan Document. 23 27 (c) Upon the occurrence of any Event of Default, Lender shall have the right, immediately and without notice, to take possession of and exercise possessory rights with regard to any Property securing payment of amounts due hereunder or under any other Loan Document. (d) If Lender shall exercise its option to take over management of the Premises pursuant to Section 8.2(b), Lender shall be authorized to employ one or more independent managers to manage the Premises, and Lender shall have no liability or responsibility absent gross negligence or willful misconduct to Borrower or any other Person with respect to its management of the Premises so long as Lender exercises good faith in the selection and retention of such independent manager or managers.

No failure or delay on the part of Lender in exercising any power or right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. No course of dealing between Borrower and Lender shall operate as a waiver of any right of Lender. No modification or waiver of any provision of this Agreement, the Note or any other Loan Document nor consent to any departure by Borrower therefrom shall in any event be effective unless the same shall be in writing, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given.
