Operating Costs (a) Tenant shall maintain the Premises in their condition on the Effective Date at Tenant’s sole cost and expense. Landlord may inspect the Premises and, if Landlord reasonably determines that Tenant is not maintaining the Premises in their condition on the Effective Date, Landlord may provide Tenant with written notice of any such maintenance concern, and Tenant shall promptly make such repairs. If Tenant fails to complete such repairs within thirty (30) days of receipt of such notice, Landlord may undertake such repairs and Tenant shall be obligated to reimburse Landlord for its costs within ten (10) days of receipt of an invoice therefore. Landlord represents and warrants to Tenant that the exterior walls, foundation and roof of the Premises are in good working order on the Effective Date. Landlord will, at its cost, replace, restore, repair or maintain (as necessary) the roof until the first anniversary of the Commencement Date. Landlord will, at its cost, replace, restore, repair or maintain (as necessary) the exterior walls and foundation of the Premises until the fifth anniversary of the Commencement Date. Tenant shall be fully responsible for the replacement, restoration, repair and maintenance of the roof, exterior walls and foundation of the Premises thereafter. If Landlord fails to commence such repairs within thirty (30) days of receipt of any notice from Tenant, Tenant may undertake such repairs and Landlord shall be obligated to reimburse Tenant for its costs within ten (10) days of receipt of an invoice therefore; provided, however, that Tenant shall have no rights to offset or set off any such amounts against the Rent to be paid hereunder. If Landlord does not reimburse Tenant within ten (10) days from the date of notice, such charge shall bear interest at the rate of eighteen percent (18%) per annum until paid. Notwithstanding anything to the contrary herein contained (except for the provisions of paragraph 32 below), if Tenant makes any changes, additions or alterations to the roof of the Premises which involves penetration of the roof (other than those for telecommunications installations so long as the installation contractor has Landlord’s prior written approval which will not be unreasonably conditioned, delayed or denied), Landlord’s obligations to replace, restore, repair or maintain the roof shall cease. If Tenant undertakes any structural repairs in the Premises which impact, affect, or alter the walls or foundation of the Premises, Landlord’s obligation to replace, restore, repair or maintain that portion of the exterior walls and foundation of the Premises shall cease as of the date of such action by Tenant. Any Operating Costs that pertain to a period prior to or after the Lease Term will be pro rated between Landlord and Tenant in the proportion of the amount of the Lease Term that falls within the period to which the Operating Costs pertain.
