Notwithstanding anything to the contrary in the Assignment and Assumption Agreement, Chelexa may, at any time, sell, transfer, encumber, assign, or pledge its right to receive the Royalty Payment under this Agreement.

8.1. Tenant's Right to Encumber. Tenant may, at any time, encumber all or any portion of its interest in this Lease and the leasehold estate by deed of trust, mortgage, or other security instrument upon obtaining the prior written consent of Landlord, which consent shall not be unreasonably withheld, and shall be further conditioned upon the agreement of the leasehold mortgagee to simultaneously deliver default notices to Landlord and Tenant. Each such mortgage, deed of trust, or other security instrument acquired by the holder of any leasehold mortgage shall be subject and subordinate to all rights and interests of Landlord herein and shall be a lien only on Tenant's interests in and to this Lease and the leasehold estate created hereby and shall not be a lien on Landlord's fee interest in the Premises or reversionary interest in the improvements. Each leasehold mortgage shall be subject to the terms and provisions of this Lease; and the holder of any leasehold mortgage, or anyone claiming by, through, or under the same, shall not, by virtue thereof, acquire any greater rights hereunder than Tenant has under this Lease. Tenant shall deliver to Landlord copies of all documents recorded to evidence any and all leasehold mortgages and all notices of default received by Tenant from the holder of any leasehold mortgage.
