Maintenance and Repairs (1) Except for matters specified under Paragraph 4 above and Paragraph 8A(3) below as being Landlord's obligation, Tenant shall, at Tenant's sole cost and expense, maintain the Premises in good order, condition and repair, ordinary wear and tear and damage by fire and casualty excepted, including: the interior surfaces of the ceilings, walls and floors; all doors and interior windows; furnishings installed within the Premises; all equipment installed by or at the expense of Tenant; and all plumbing, heating, ventilating, electrical and lighting facilities and fixtures; all landscaping, parking lots, fences and signs located within the Premises. (2) In the event that Tenant fails to maintain the Premises in good order, condition and repair as required under this Lease, Landlord shall give Tenant prior written notice to do such acts as are required to so maintain the Premises. In the event that Tenant fails to commence such work within 30 days after written demand by Landlord, and diligently prosecute it to completion, then Landlord shall have the right, but shall not be obligated, to do such acts and expend such funds at the expense of Tenant as are reasonably required to perform such work. Landlord shall have no liability to Tenant for any reasonable damage, inconvenience or interference with Tenant's use of the Premises as a result of performing any such work. (3) Landlord will maintain, repair and replace all structural components of the Premises and the roof of the Building, and if a repair, replacement or alteration or other change would be considered a capital improvement or replacement to the Premises under generally accepted accounting principles, then it shall be Landlord's responsibility to promptly make and pay for such repair, replacement, alteration or other change. The cost of any such capital improvement shall be amortized over the useful life of such item and Tenant agrees to pay its percentage share (which shall be determined by dividing the square footage of the Building by the square footage of all buildings benefitted by such improvement, including the Building) of the annual amortized amount. Such payment will be made by Tenant as set forth in Paragraph 4 above. Landlord shall do all acts required to comply with all applicable laws, ordinances, regulations and rules of any public authority relating to the Premises, except to the extent that the foregoing are solely a result of Tenant's use of the Premises. Tenant shall do all acts required to comply with all applicable laws, ordinances, regulations and rules of any public authority relating solely to Tenant's use of the Premises. If a repair is required as a result of Tenant's negligence and such repair cost is not covered by insurance proceeds, Tenant will pay for the cost of such repair. Notwithstanding anything in this Lease to the contrary, in the event that the need for repairs or the making of repairs (or both) which Landlord is obligated to effect at Landlord's expense renders a material portion of the Premises unusable for more than three consecutive business days, then Tenant shall be entitled to an abatement of rent commencing with the fourth business day that the same are unusable; provided, however, that Tenant shall not be entitled to a pro rata abatement of rent under the foregoing due to unusability (i) caused directly or indirectly by any act or omission of Tenant or any of Tenant's servants, employees, agents, contractors, visitors or licensees, (ii) where Tenant makes a decoration, alteration, improvement or addition which directly causes such unusability, or (iii) where the repair in question is one which Tenant is obligated to furnish under the provisions of this Lease.
