Abatement of Rent In the event that Tenant is prevented from using the Premises or any material portion thereof (meaning that Tenant is unable to use that portion of the Premises in the normal course of its business) as a result of (i) any repair, maintenance or alteration negligently performed by Landlord, or which Landlord failed to perform, as required by this Lease; or (ii) the presence of, or cleanup or remediation activities in connection with, Hazardous Materials brought on the Premises by Landlord or a Landlord Party; or (iii) cessation of utilities or services caused by Landlord’s negligence or willful misconduct (any such set of circumstances as set forth in items (i) through (iii), above, to be known as an “Abatement Event”), then Tenant shall give Landlord written notice of such Abatement Event, and if such Abatement Event continues for two (2) consecutive business days after such notice, or occurs for ten (10) non-consecutive business days in a twelve (12) month period (in either of such events, the “Eligibility Period”), then the Base Rent and Additional Rent shall be abated or reduced, as the case may be, after expiration of the Eligibility Period for such time that Tenant continues to be so prevented from using the Premises, or a portion thereof, in the proportion that the floor area of the portion of the Premises that Tenant is prevented from using (“Unusable Area”), bears to the total floor area of the Premises. If Landlord has not cured such Abatement Event within one hundred eighty (180) days after receipt of written notice from Tenant, Tenant shall have the right to terminate this Lease during the first ten (10) business days of each calendar month following the end of such 180-day period until such time as Landlord has cured the Abatement Event, which right may be exercised only by delivery of thirty (30) days’ notice to Landlord and Landlord’s Lender (provided such Lender’s name and notice address were previously provided to Tenant) (the “Abatement Event Termination Notice”) during such ten (10) business-day period, and shall be effective as of a date set forth in the Abatement Event Termination Notice (the “Abatement Event Termination Date”), which Abatement Event Termination Date shall not be less than thirty (30) days, and not more than one (1) year, following the delivery of the Abatement Event Termination Notice. Tenant’s Abatement Event Termination Notice shall be null and void (but only in connection with the first notice sent by Tenant with respect to each separate Abatement Event) if Landlord or Landlord’s Lender(s) cures such Abatement Event within such thirty (30) day period following receipt of the Abatement Event Termination Notice.
