Without notice or consent of Mortgagor, renewals and extensions of the written instruments constituting part or all of the Obligations may be given at any time and amendments may be made to agreements relating to any part of such written instruments or the Collateral. Mortgagee may take or hold other security for the Obligations without notice to or consent of Mortgagor. The acceptance of this Mortgage by Mortgagee shall not waive or impair any other security Mortgagee may have or hereafter acquire to secure the payment of the Obligations nor shall the taking of any such additional security waive or impair the Lien and security interests herein granted. Mortgagee may resort first to such other security or any part thereof, or first to the security herein given or any part thereof, or from time to time to either or both, even to the partial or complete abandonment of either security, and such action will not be a waiver of any rights conferred by this Mortgage. This Mortgage may not be amended, waived or modified except in a written instrument executed by both Mortgagor and Mortgagee. The provisions of this Section 7.4 are granted to the extent permissible by applicable law.
