Maintenance, Repairs and Alterations 6.01 Tenant's Obligations to Repair ------------------------------ Tenant shall at its sole cost and expense, maintain in clean and safe condition, and make all repairs and replacements to the Premises and every part thereof, structural and non-structural, so as to keep, maintain and preserve the Premises in first class condition and repair, including, without limitation, the roof, the foundation, the heating, ventilation and air conditioning system ("HVAC"), elevators, if any, all plumbing and sewage facilities, fire sprinklers, electrical and lighting facilities, systems, appliances, and equipment within the Premises, fixtures, interior and exterior walls, floors, ceilings, windows, doors, entrances, all interior and exterior glass (including plate glass), and skylights located within the Premises, and all sidewalks, service areas, parking areas and landscaping comprising part of the Premises. All repairs and replacements required to be made by Tenant shall be made promptly with new materials of like kind and quality to those used in the original construction of the Premises. If the repair or replacement work affects the structural parts of the Premises, or if the estimated cost of any item or repair or replacement exceeds $10,000, then Tenant shall first obtain Landlord's written approval of the scope of work, plans therefor, and materials to be used. Any such work shall be performed by Landlord's contractor or by such contractor as Tenant may choose from an approved list to be submitted by Landlord. Landlord shall have the right to make any repairs or replacements which are not promptly made by Tenant and charge Tenant, as Additional Rent, for the cost thereof together with interest thereon at the Agreed Rate from the date of payment thereof by Landlord. Without limiting any of Tenant's obligations hereunder, during the Lease Term Tenant, at its expense, shall obtain and keep in force an HVAC service contract and a roof maintenance program satisfactory to Landlord. Tenant hereby waives the benefit of any statute now or hereafter in effect which would otherwise afford Tenant the right to make repairs at Landlord's expense or to terminate this Lease because of Landlord's failure to keep the Premises in good condition, order and repair. Tenant specifically waives all rights it may have under Sections 1932(1), 1941 and 1942 of the California Civil Code, and any similar or successor statute or law. Notwithstanding anything to the contrary contained herein, Landlord shall exercise its rights under any guaranties or warranties relating to the original construction of the Premises if the need to make repairs arises due to a defect therein; provided, however, Landlord shall not have any liability or be required to expend any funds if such guaranties or warranties are not honored by the makers hereof.
ALTERATIONS AND IMPROVEMENTS Tenant shall make no alterations to the buildings or improvements on the Premises or construct any building or make any other improvements on the Premises without the prior written consent of Landlord. Any and all alterations, changes, and/or improvements built, constructed or placed on the Premises by Tenant shall, unless otherwise provided by written agreement between Landlord and Tenant, be and become the property of Landlord and remain on the Premises at the expiration or earlier termination of this Agreement.
