UNAVOIDABLE DELAYS AND INTERRUPTION OF SERVICE

10.1. Unavoidable Delays.

Subject to Article 15 hereof and Article 16 hereof, this Lease and the obligation of Tenant to pay Rental hereunder and to perform all of Tenant’s other covenants shall not be affected, impaired or excused, and Landlord shall not have any liability to Tenant, to the extent that Landlord is unable to perform Landlord’s covenants under this Lease by reason of any cause beyond Landlord’s reasonable control, including, without limitation, strikes, labor troubles, acts of terrorism or the occurrence of an act of God; provided, however, that Landlord shall not have the right to claim under this Section 10.1 that Landlord’s failure to have funds available to make a payment of money constitutes an excuse for Landlord’s performance of an obligation of Landlord hereunder.

10.2. Interruption of Services.

Landlord, from time to time, shall have the right to interrupt or curtail the level of service provided by the Building Systems to the extent reasonably necessary to accommodate the performance of repairs, additions, alterations, replacements or improvements that in Landlord’s reasonable judgment are desirable or necessary. Landlord shall give Tenant reasonable advance notice of any such interruption or curtailment (to the extent that Landlord does not need to arrange for such interruption or curtailment to manage an emergency) and schedule any such interruption or curtailment at times that minimizes, to the extent reasonably practicable, the effect of such interruption or curtailment on Tenant’s ability to conduct its business in the Premises during Tenant’s ordinary business hours. If such interruption or curtailment of the level of service provided by the Building Systems (i) denies Tenant from having reasonable access to the Premises, (ii) threatens the health or safety of any occupant of the Premises, or (iii) materially interferes with Tenant’s ability to conduct its business in the Premises during Tenant’s ordinary business hours, then Landlord shall employ contractors or labor at overtime or premium pay rates to the extent reasonably necessary. Landlord, at Tenant’s request, shall also schedule any such interruption or curtailment, to the extent reasonably practicable, using contractors or labor at overtime or premium pay rates, in which case Tenant shall pay to Landlord, as additional rent, an amount equal to the excess of (x) the Out-of-Pocket Costs that Landlord incurs in so scheduling such interruption or curtailment (using contractors or labor at overtime or premium pay rates), over (y) the Out-of-Pocket Costs that Landlord would have incurred in scheduling such interruption or curtailment without using contractors at overtime or premium pay rates, within thirty (30) days after the date that Landlord gives to Tenant an invoice therefor together with reasonable supporting documentation for the charges set forth therein (it being understood that if more than one tenant requests that Landlord conduct such Work Access using contractors or labor at overtime or premium pay rates, then Landlord shall allocate such costs among such tenants equitably).

10.3. Rent Credit.

Subject to the terms of this Section 10.3, if (I) (i) Landlord fails to perform Landlord’s covenants hereunder, (ii) Landlord interrupts or curtails the level of service provided by Building Systems as contemplated by Section 10.2 hereof, or (iii) Landlord performs repairs, alterations, improvements, additions or restorations in the Building, and (II) Tenant, by reason of the event described in clause (I) above, is unable for at least fifteen (15) consecutive Business Days to operate Tenant’s business in the Premises (or a portion thereof) in substantially the same manner that Tenant conducted its business prior to such event, then Tenant shall be entitled to a credit to apply against the Fixed Rent thereafter coming due hereunder in an amount equal to the product obtained by multiplying (A) the quotient obtained by dividing (a) the sum of the Fixed Rent for the Premises, by (b) three hundred sixty-five (365) (or three hundred sixty-six (366) in a leap year), by (c) the number of square feet of Rentable Area in the Premises, by (B) the number of square feet of Rentable Area of the portion of the Premises which is unusable, as aforesaid, by (C) the number of days in the period commencing on (and including) the date immediately following the date that is fifteen (15) Business Days after the event that is described in clause (I) above and ending on the date that such portion of the Premises becomes usable. If (x) Tenant is entitled to a credit against Rental pursuant to this Section 10.3, and (y) the Expiration Date occurs prior to the date that such credit is exhausted, then Landlord shall pay to Tenant the unused portion of such credit on or prior to the thirtieth (30th) day after the Expiration Date (and Landlord’s obligation to make such payment shall survive the Expiration Date). This Section 10.3 shall not apply in respect of the occurrence of a fire or other casualty or in respect of a condemnation. This Section 10.3 shall not limit the provisions of Section 5.2 hereof.
