[Code of Federal Regulations] [Title 36, Volume 1] [Revised as of July 1, 2001] From the U.S. Government Printing Office via GPO Access [CITE: 36CFR18.10] [Page 233] TITLE 36--PARKS, FORESTS, AND PUBLIC PROPERTY CHAPTER I--NATIONAL PARK SERVICE, DEPARTMENT OF THE INTERIOR PART 18--LEASES AND EXCHANGES OF HISTORIC PROPERTY--Table of Contents Sec. 18.10 Subleases and assignments. (a) A sublease, assignment, amendment or encumbrance of any lease issued under this part may be made only with the written approval of the Director. (b) A lease may be amended from time to time at the written request of either the lessee or the Government with written concurrence of the other party. Such amendments will be added to and become a part of the original lease. (c) The lease may contain a provision authorizing the lessee to sublease the premises, in whole or in part, with approval of the Director, provided the uses prescribed in the original lease are not violated. Subleases so made shall not serve to relieve the sublessee from any liability nor diminish any supervisory authority of the Director provided for under the approved lease. (d) With the consent of the Director, the lease may contain provisions authorizing the lessee to encumber the leasehold interest in the premises for the purpose of borrowing capital for the development and improvement of the leased premises. The encumbrance instrument must be approved by the Director in writing. An assignment or sale of leasehold under an approved encumbrance can be made with the approval of the Director and the consent of the other parties to the lease, provided, however, that the assignee accepts and agrees in writing to be bound by all the terms and conditions of the lease. Such purchaser will be bound by the terms of the lease and will assume in writing all the obligations thereunder.
