toward payment of the next monthly installment of Minimum Rent to be paid by Tenant after Tenant receives said statement from Landlord. If the amount paid by Tenant during the last calendar year of the Lease Term exceeds Tenant’s pro rata share
of actual Operating Expenses for such year, Landlord shall pay Tenant the excess amount within thirty (30) days after Landlord’s submission to Tenant of the aforesaid Operating Expenses statement for such calendar year. 

d. Landlord’s failure or delay in rendering any statement contemplated by this Section shall not constitute a waiver of Landlord’s
right thereafter and during the term of this Lease to render such statement.

Tenant asserts specific error(s) and supports such errors, in writing, within thirty (30) days after Landlord has complied with Tenant’s request, Tenant shall waive the right to contest the statement of actual figures for the year
submitted by Landlord. If it shall be determined that there is an error in Landlord’s statement, Tenant shall be entitled to a credit for any overpayment. Any payment, refund or credit made pursuant to Section 5.A. or Section 6 shall be

	25.	EVENTS OF DEFAULT 

 The occurrence of any of the following shall constitute an event of
default hereunder: 
  

	 	(a)	Failure of Tenant to pay installment of rent within five (5) days of the due date, or failure of Tenant to pay within fifteen (15) days after receipt of written notice any other sum herein required to be paid
by Tenant. Notwithstanding the foregoing, Landlord shall be required to deliver to Tenant written notice of the failure to pay Minimum Rent and/or such payments of Operating Expenses one (1) time in every twelve (12)-month period, in which
event Tenant shall be deemed to be in default only if such failure continues for five (5) business days after receipt of such written notice from Landlord. 

  

	 	(b)	Tenant’s failure to perform any other covenant or condition of this Lease within thirty (30) days after receipt of written notice and demand, unless the failure is of such a character as to require more than
thirty (30) days to cure in which event Tenant’s failure to proceed diligently to cure such failure shall constitute an event of default. 

  

	26.	LANDLORD’S REMEDIES 

 Upon the occurrence of any event of default, Landlord may, at
Landlord’s sole option, exercise any or all of the following remedies, together with any such other remedies as may be available to Landlord at law or in equity. 
  

	 	(a)	Landlord may terminate this Lease by giving Tenant written notice of its election to do so, as of a specified date not less than thirty (30) days after the date of the giving of such notice and this Lease shall
then expire on the date so specified, and Landlord shall then be entitled to immediately regain possession of the Premises as if the date had been originally fixed as the expiration date of the term of this Lease. Landlord may then re-enter upon the
Premises, either with or without due process of law, and remove all persons therefrom, the statutory notice to quit or any other notice to quit being hereby expressly waived by Tenant. Tenant expressly agrees that the exercise by Landlord of the
right of re-entry shall not be a bar to or prejudice in any way other legal remedies available to Landlord. In that event, Landlord shall be entitled to recover from Tenant as and for liquidated damages an amount equal to the rent and additional
rent reserved in this Lease less any and all amounts received by Landlord from the rental of the Premises to another tenant. Nothing herein contained, however, shall limit or prejudice the right of Landlord to prove for and obtain as liquidated
damages, by reason of such termination, an amount equal to the maximum allowed by any statute or rule of law in effect at the time when, and governing the proceedings in which such damages are to be proved, whether or not such amount may be greater,
equal to, or less than the amount of the difference referred to above, and the Landlord may, in his own name, but as agent for Tenant, re-let the Premises. Any recovery by the Landlord shall be limited to the rent hereunder (plus any costs incurred
in re-letting) less any rent actually paid by the new tenant. 

  

	 	(b)	No termination of this Lease or any taking of possession of the Premises shall deprive Landlord of any of its remedies or actions against Tenant for past or future rent, nor shall the bringing of any action for rent or
breach of covenant, or the resort to any other remedy herein provided for the recovery of rent, be construed as a waiver of the right to obtain possession of the Premises. 


 

	 	(c)	In addition to any damages becoming due under this paragraph, Landlord shall be entitled to recover from Tenant and Tenant shall pay to Landlord an amount equal to all expenses, including attorneys’ fees, if any,
incurred by the Landlord in recovering possession of the Premises, and all reasonable costs and charges for the care of said Premises while vacant, which damages shall be due and payable by Tenant to Landlord at such time or times as such expenses
are incurred by the Landlord. 

  

	 	(d)	In the event of a default or threatened default by Tenant of any of the terms or conditions of this Lease, Landlord shall have the right of injunction and the right to invoke any remedy allowed by law or in equity as if
no specific remedies of Landlord were set forth in this Lease. 

  

	 	(e)	If default be made and a compromise and settlement shall be had thereupon, it shall not constitute a waiver of any covenant herein contained, nor of the Lease itself. 


 

	27.	RIGHTS OF LANDLORD 

 Landlord reserves the following rights with respect to the Premises:

  

	 	(a)	During normal business hours, upon 24 hours notice, to go upon and inspect the Premises, and at Landlord’s option, to make repairs, alterations and additions to the Premises or the Building of which the Premises
are a part, provided there is no interference with Tenant’s occupancy. An Agent of the Tenant may be present for inspection, if requested by Tenant. 

  

	 	(b)	To display, within sixty (60) days prior to the expiration of this Lease or after notice from either party of intention to terminate this Lease, a “For Rent” sign, and all of said signs which shall be
placed upon such part of the Premises as Landlord shall determine, except on doors leading into the Premises. Prospective purchasers or tenants authorized by Landlord may inspect the Premises during normal business hours following adequate notice to
Tenant. 

  

	 	(c)	To install, place upon, or fix to the roof and exterior walls of the Premises, equipment, signs, displays, antennae, and any other object or structure of any kind, providing the same shall not materially impair the
structural integrity of the Building or interfere with Tenant’s occupancy.

	28.	HOLDING OVER 

 If Tenant holds possession of the Leased Premises after the Expiration
Date or other termination of this Lease, Landlord shall, at its sole option, have the right to treat Tenant as a tenant by the month commencing with the first day after the termination of the Lease at one hundred fifty percent (150%) the
monthly Minimum Rent paid during the last month of the Term, and upon all the other terms of this Lease, including the provisions of this paragraph. Said holdover term shall terminate upon thirty (30) days notice from one party to the other.
Notwithstanding the foregoing, nothing contained herein shall be construed as a requirement that Landlord consent to the occupancy or possession of the Leased Premises by Tenant after the termination of the Lease, and Landlord, upon said termination
of this Lease, if Landlord elects to treat Tenant as a trespasser, shall be entitled to the benefit of all public general or public laws relating to the speedy recovery of the possession of land and tenements held over by Tenant, whether now or
hereafter in force and effect. 
  

	29.	WAIVER OF CLAIMS 

 Except as may result from their negligence, Landlord and
Landlord’s agents, employees, and contractors shall not be liable for, and Tenant hereby releases all claims for, damages to persons or property sustained by Tenant (or any person claiming through Tenant) resulting from any fire, accident,
occurrence or condition in or upon the Premises or Building, including but not limited to such claims for damage resulting from (1) any defect in or failure of plumbing, heating or air-conditioning equipment, electric wiring or installation
thereof, water pipes, stairs, railings or walks; (2) any equipment or apparatus becoming out of repair; (3) the bursting, leaking or running of any tank, washstand, water closet, waste pipe, drain or any other pipe or tank, upon or about
