 18.2
Landlord’s Remedies. 
 (a) If an Event of Default as set forth in Section 18.1(a) occurs then Landlord
has the right, without further demand or notice, to commence summary proceedings in the City Court of Buffalo seeking an order of eviction permitting Landlord to reenter and take possession of the Premises or any part of the Premises, repossess the
same, expel Tenant and those claiming through or under Tenant, and remove the effects of both or either, using such force for such purposes as may be necessary, without being liable for prosecution, without being deemed guilty of any manner of
trespass, and without prejudice to any remedies for arrears of Rent or other amounts payable under this Lease or as a result of any preceding breach of covenants or conditions. 

(b) If any one or more of the Events of Default set forth in Section 18.1(b)-(g) occurs then Landlord has the right,
at its election: 
 (i) to give Tenant five (5) business days’ written notice of the expiration of the Term and upon the giving of
such notice and the expiration of such five (5) business day period, Tenant’s right to possession of the Premises will cease and this Lease will be terminated, except as to Tenant’s liability, as if the expiration of the term fixed in
such notice were the end of the Term; or 
 (ii) without further demand or notice to cure any Event of Default and to charge Tenant for the
cost of effecting such cure, including without limitation reasonable attorneys’ fees and interest on the amount so advanced at the rate of eight percent (8%) per annum, provided that Landlord will have no obligation to cure any such Event of
Default of Tenant. Should Landlord take possession pursuant to legal proceedings or pursuant to any notice provided by law, Landlord shall take all commercially reasonable efforts to, without terminating this Lease,

relet the Premises or any part of the Premises in Landlord’s or Tenant’s name, but for the account of Tenant, for such term or terms (which may be greater or less than the period which
would otherwise have constituted the balance of the Term) and on such conditions and upon such other terms (which may include concessions of free rent and alteration and repair of the Premises) as Landlord, in its reasonable discretion, may
determine, and Landlord may collect and receive the rent, and in Landlord’s sole discretion, apply such rents against the penalties, fees, and rents due to Landlord by Tenant Landlord will in no way be responsible or liable for any failure to
relet the Premises, or any part of the Premises, or for any failure to collect any rent due upon such reletting. No such reentry or taking possession of the Premises by Landlord will be construed as an election on Landlord’s part to terminate
this Lease unless a written notice of such intention is given to Tenant No written notice from Landlord under this Section or under a forcible or unlawful entry and detainer statute or similar law will constitute an election by Landlord to terminate
this Lease unless such notice specifically so states. Landlord reserves the right following any such reentry or reletting to exercise its right to terminate this Lease by giving Tenant such written notice, in which event this Lease will terminate as
specified in such notice. 
 18.3 Certain Damages. In the event that Landlord does not elect to terminate this Lease as permitted in
Section 18.2, but on the contrary elects to take possession as provided in Section 18.2, Tenant will pay to Landlord Rent (including any Additional Rent) and other sums as provided in this Lease
that would be payable under this Lease if such repossession had not occurred, less the net proceeds, if any, of any reletting of the Premises after deducting all of Landlord’s reasonable expenses in, connection with such reletting, including
without limitation all repossession costs, brokerage commissions, attorneys’ fees, expenses of employees, alteration and repair costs, and expenses of preparation for such reletting. If, in connection with any reletting, the new lease term
extends beyond the scheduled expiration of the existing Term, or the Premises covered by such new lease include other premises not part of the Premises, a fair apportionment of the rent received from such reletting and the expenses incurred in
connection with such reletting as provided in this Section will be made in determining the net proceeds from such reletting, and any rent concessions will be equally apportioned over the term of the new lease. Tenant will pay such rent and other
sums to Landlord on the days on which the Rent would have been payable under this Lease if possession had not been retaken, and Landlord will be entitled to receive such Rent and other sums from Tenant on each such day. 

18.4 Continuing Liability After Termination. If this Lease is terminated on account of the occurrence of an Event of Default, Tenant
will remain liable to Landlord for damages in an amount equal to Rent (including any Additional Rent) and other amounts that would have been owing by Tenant for the balance of the Term, had this Lease not been terminated, less the net proceeds, if
any, of any reletting of the Premises by Landlord subsequent to such termination, after deducting all of Landlord’s reasonable expenses in connection with such reletting in accordance with Section 18.3. Landlord shall
be entitled to collect such reasonable damages from Tenant on the days on which Rent (including any Additional Rent) and other amounts would, have been payable under this Lease if this Lease had not been terminated, and Landlord shall be entitled to
receive such Rent (including any Additional Rent) and other amounts from Tenant on each such day. 
 18.5 Cumulative Remedies. Any
suit or suits for the recovery of the amounts and damages set forth in Sections 183 and 18.4 may be brought by Landlord, from time to time, at Landlord’s election, and nothing in this Lease will be deemed to require Landlord to await the
date upon which this Lease would have expired had there occurred no Event of Default Each right and remedy provided for in this Lease is cumulative and is in addition to every other right or remedy provided for in this Lease now or after the
Commencement Date existing at law or in equity or by statute or otherwise, and the exercise or beginning of the exercise by Landlord of any one or more of the rights or remedies provided for in this Lease now or after the. Commencement Date existing
at law or in equity or by statute or otherwise will not preclude the simultaneous or later exercise by Landlord of any or all other rights or remedies provided for in this Lease now or after the Commencement Date existing at law or in equity or by
statute or otherwise. All costs incurred by Landlord in collecting any amounts, and damages owing by Tenant pursuant to the provisions of this Lease or to enforce any provision of this Lease, including reasonable attorneys’ fees from the date
any such matter is turned over to an attorney, whether or not one or more actions are commenced by Landlord, will also be recoverable by Landlord from Tenant.

	ARTICLE 20.	 FAILURE TO INSIST ON STRICT PERFORMANCE 



20.1 The failure of either party to insist, in any one or more instances, upon a strict performance of any covenant, term, provision or
agreement of this Lease shall not be construed as a waiver or relinquishment thereof, but the same shall continue and remain in full force and effect, notwithstanding any law, usage or custom to the contrary. The receipt by Landlord of Rent with
