Alterations, Additions, and Improvements Subject to the provisions of this Article IV, Lessee may make any alterations, additions, improvements or other changes to the Premises and the Relevant Assets as may be necessary or useful in connection with the operation of the Relevant Assets (collectively, the “Additional Improvements”). If such Additional Improvements require alterations, additions or improvements to the Premises or any of the Shared Access Facilities, Lessee shall notify Lessor in writing in advance and the parties shall negotiate in good faith any increase to the fees paid by Lessee under the Site Services Agreement by Lessee or otherwise provide for reimbursement of any material increase in cost (if any) to Lessor under the Site Services Agreement that results from any modifications to the Premises or the Shared Access Facilities necessary to accommodate the Additional Improvements, or as otherwise mutually agreed by the parties. Any alteration, addition, improvement or other change to the Premises, Relevant Assets or Additional Improvements (and, if agreed by Lessee and Lessor, to the Shared Access Facilities) by Lessee shall be made in a good and workmanlike manner and in accordance with all applicable Laws. The Relevant Assets and all Additional Improvements shall remain the property of Lessee and shall be removed by Lessee within one (1) year after termination of this Lease (provided that such can be removed by Lessee without unreasonable damage or harm to the Premises) or, at Lessee’s option exercisable by notice to Lessor, surrendered to Lessor upon the termination of this Lease. Lessee shall not have the right or power to create or permit any lien of any kind or character on the Premises by reason of repair or construction or other work. In the event any such lien is filed against the Premises, Lessee shall cause such lien to be discharged or bonded within thirty (30) days of the date of filing thereof.
