written notice to Tenant and the rent shall, in such event, be paid to or adjusted as of the lapse of time upon the third day after such notice is mailed, and Tenant shall thereupon vacate the Premises and surrender the same to Landlord, but no such

 such partial taking, Tenant is reasonably able to sue the remainder of the Premises for the purposes intended hereunder,
then this Lease shall not terminate, but, rent hereunder shall be abated in any amount thereof proportionate to the area of the Premises for the purposes intended hereunder, then this Lease shall terminate as if the entire Premises had been taken,
leased or condemned. In the event of a taking, lease or condemnation as described in this Article, whether or not there is a termination hereunder, Tenant shall have no claim against Landlord other than adjustment of rent to the date of taking lease
or condemnation, and Tenant shall not be entitled to any portion of any amount that may be awarded as damages or paid as a result or in settlement of such proceedings or threat.

agrees to pay Landlord an additional amount of rental equal to the attorney’s fees incurred by the Landlord during said litigation. 
  
 b. In the event of any failure of Tenant to pay rental due hereunder within five (5) days after the same shall be due, or any failure to perform any other
of the terms, conditions or covenants of this Lease to be observed or performed by Tenant for more than thirty (30) days after written notice of such default shall have been mailed to Tenant, or if Tenant shall become bankrupt or insolvent, or file
any debtor proceedings or take or have taken against Tenant in any court pursuant to any statute either of the United States or of any State, a petition in bankruptcy or insolvency or for reorganization or for the Tenant’s property, or if
Tenant makes an assignment for the benefit of creditors or petitions for or enters into an arrangement, or if tenant shall abandon the leased property, or suffer this Lease to be taken under any writ of execution, then Landlord, besides other rights
or remedies it may have, shall have the immediate right of re-entry and may remove all persons and property from the leased property and such property may be removed and stored in a public warehouse or elsewhere at the cost of and for the account of
tenant, all without service or notice or resort to legal process and without being deemed guilty of trespass or becoming liable for any loss or damage which may be occasioned thereby. 
  
 c. Should Landlord elect to re-enter as herein provided, or should it take possession pursuant to legal proceedings or
pursuant to any notice provided for by law, it may either terminate this Lease, or it may from time to time without terminating this Lease, make such alterations and repairs as may be necessary in order to relit the property, and relit the property,
or any part thereof, for such term or terms (which may be for a term extending beyond the term of this Lease) and at such rental or rentals and upon such

received by Landlord from such reletting shall be applied, first, to the payment of any indebtedness other than rent due hereunder from Tenant to Landlord; second, to the payment of any costs and expenses of such reletting, including brokerage fees
and attorney’s fees and cost of such alterations and repairs; third, to the payment of rent due and unpaid hereunder and the residue, if any, shall be held by Landlord and applied in payment of future rent as the same may become due and payable
hereunder. If such rentals received from such reletting during any month be less than that to be paid during that month by Tenant hereunder, Tenant shall pay any such deficiency to Landlord. Such deficiency shall be calculated and paid monthly. No
such re-entry or taking possession of the leased property by Landlord shall be construed as an election on its part to terminate this Lease unless a written notice of such intention be given to Landlord or unless the termination thereof be decreed
by a court of competent jurisdiction. Notwithstanding any such reletting without this Lease for such previous breach. Should Landlord at any time terminate this Lease for any breach, in addition to any other remedies it may have, it may recover from
Tenant all damages it may incur by reason of such breach, including the cost of recovering the leased property, reasonable attorney’s fees, and including the amount of rent and charges equivalent to rent reserved in this Lease for the remainder
of the stated term over the then reasonable rental value of the leased property for the remainder of the stated term, all of which amounts shall be immediately due and payable from Tenant to Landlord. 
  
 27. Waiver. 
  
 The receipt of rent by the Landlord, whether the same by that originally
reserved or that which may be payable under any of the covenants and/or agreements herein contained, or any part thereof, shall not be deemed to operate as a waiver of the right of Landlord to enforce the same of any other covenants and conditions
on the occasion of a subsequent breach or default. No waiver or consent of Landlord or its successor or assigns, given hereunder, in any instance, shall operate as a waiver of any provision of this agreement, except for that instance alone.

entities, whether or not operating as a partnership or joint venture, then each such individual corporation, entity, joint venture or partner shall be deemed to be both jointly and severally liable for the payment of the entire rent and other
