In case of such taking of part of the Premises, if the remainder is insufficient for use for Lessee's purposes, and the Lessor receives with the notice hereinafter referred to a certificate to the effect signed by Lessee, or in case of such damage or taking if the time needed to do the construction work necessary to put the Premises or such remainder in proper condition for use and occupation is reasonably estimated by Lessor to exceed six (6) months, Lessee may terminate this Lease by notice given to Lessor within sixty (60) days after the right to terminate arises specifying the effective date of termination.

If in any such case the Premises are rendered unfit for use and occupancy and the Lease is not so terminated, Lessor shall use due diligence (following the expiration of all periods in which either party may terminate this Lease pursuant to the foregoing provisions of this Section 6.1) to put the Premises, or in case of taking what may remain thereof (excluding any terms installed or paid for by Lessee which Lessee may be required to remove pursuant to Section 5.2), into proper condition for use and occupancy and a just proportion of the fixed rent and additional rent according to the nature and extent of the injury shall be abated until the Premises or such remainder shall have been put by Lessor in such condition; and in case of taking which permanently reduces the area of the premises, a just proportion of the fixed rent and additional rent shall be abated for the remainder of the Lease Term. 6.2 Eminent Domain Damages Reserved. Lessor reserves to itself any and all rights to receive awards made for damages to the Premises, the Buildings and Lot and the leasehold hereby created, or any one or more of them, accruing by reason of exercise of eminent domain or by reason of anything lawfully done in pursuance of public or other authority. Lessee hereby releases and assigns to Lessor all Lessee's rights to such awards, and covenants to deliver such further assignments and assurances thereof as Lessor may from time to time request, hereby irrevocably designating and appointing Lessor as its attorney-in- fact to execute and deliver in Lessee's name and behalf all such further assignments thereof. 6.3. Temporary Taking.

ARTICLE VII DEFAULT 7.1 Events of Default. This Lease is made upon this condition, that if the Lessee shall neglect or fail to perform any one or more of its covenants contained herein and any such neglect or failure continues after notice, in case of fixed rent or additional rent for more than ten (10) days, or in any other case for more than thirty (30) days and such additional time, if any, as is reasonably necessary to cure the default if the default is of such a nature that it cannot reasonably be cured in said thirty (30) days; or if Lessee or any guarantor of any of Lessee's obligations under this Lease makes any assignment for the benefit of creditors, commits any act of bankruptcy or files a petition under any bankruptcy or insolvency law; or if such a petition filed against Lessee or such guarantor is not dismissed within ninety (90) days; or if a receiver or similar officer becomes entitled to Lessee's leasehold hereunder and it is not returned to Lessee within ninety (90) days; or if such leasehold is taken on execution or other process of law in any action against Lessee, then in any case, whether or not the Lease Term shall have begun, Lessor may immediately, or at any time while such default exists and without further notice, terminate this Lease by notice to Lessee, specifying a date not less than (10) days after the giving of such notice on which this Lease shall terminate and this Lease shall come to an end on the date specified therein as fully and completely as if such date were the date herein originally fixed for the expiration of the Lease Term, and Lessor, at its election, may lawfully or at any time thereafter and without further notice, enter into and upon the premises or any part thereof in the name of the whole, and repossess the same as of Lessor's former estate and expel Lessee and those claiming through or under Lessee and remove their effects (forcibly if necessary) without being deemed guilty of any manner of trespass and without prejudice to any remedies for arrears of rent or any other preceding breach of covenant and Lessor may, at its election, store any effects so removed in a public warehouse or otherwise for the amount of, and at the expense of, Lessee, and upon termination of this Lease as aforesaid or under any provision of any statute, whether or not Lessor enters the Premises, Lessee will then quit and surrender the Premises to Lessor, but Lessee shall remain liable as hereinafter provided. 7.2 Damages. In the event that this Lease is terminated under any of the provisions contained in Section 7.1 or shall be otherwise terminated for breach of any obligation of Lessee, Lessee covenants to pay forthwith to Lessor, as compensation, the excess of the total rent reserved for the residue of the Lease Term over the rental value of the Premises for said residue of the Lease Term. In calculating the rent reserved there shall be included, in addition to the Fixed Rent and all Additional Rent, the value of all other considerations agreed to be paid or performed by Lessee for said residue. Lessee further covenants as an additional and cumulative obligation after any such ending to pay punctually to Lessor all the sums and perform in the same manner and to the same extent and at the same time as if this Lease had not been terminated. In calculating the amounts to be paid by Lessee under the next foregoing covenant Lessee shall be credited with any amount paid to Lessor as compensation as in this Section 7.2 provided and also with the net proceeds of any rent obtained by Lessor by reletting the Premises after deducting all Lessor's expenses in connection with such reletting, including without limitation, all repossession costs, brokerage commissions, fees for legal services and expenses of preparing the Premises for such reletting, it being agreed by Lessee that Lessor may (i) relet the Premises or any part or parts thereof, for a term or terms which may at Lessor's option be equal to or less than exceed the period which would otherwise have constituted the balance of the Lease Term and may grant such concessions and free rent as Lessor in its sole judgement considers advisable or necessary to relet the same and (ii) make alterations, repairs and decorations in the premises as Lessor in its sole judgment considers advisable or necessary to relet the same, and no action of Lessor in accordance with the foregoing or failure to relet or to collect rent under reletting shall operate or be construed to release or reduce Lessee's liability as aforesaid. In lieu of any other damages or indemnity and in lieu of full recovery by Lessor of all sums payable under all the foregoing provisions of this Section 7.2, Lessor may by written notice to Lessee, at any time after this Lease is terminated under any of the provisions contained in Section 7.1 or is otherwise terminated for breach of any obligation of Lessee and before such full recovery, elect to recover, and Lessee shall thereupon pay, as liquidated damages, an amount equal to the aggregate of the Fixed Rent and Additional Rent accrued under Sections 2.5, 2.6 and 2.7 in the twelve (12) months ended next prior to such termination plus the amount of Fixed Rent and Additional Rent of any kind accrued and unpaid at the time of termination and less the amount of any recovery by Lessor under the foregoing provisions of this Section 7.2 up to the time of payment of such liquidated damages. Nothing in this Lease shall limit or prejudice the right of Lessor to prove for and obtain in proceedings for bankruptcy or insolvency by reason of the termination of this Lease, 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, the damages are to be proved, whether or not the amount be greater, equal to, or less than the amount of the loss or damages referred to above. In the event the Lessor becomes involved in bankruptcy, insolvency, or assignment for the benefit of creditors by the Lessor, the Lessee shall have the right to cancel this Lease, provided that said conditions are not cured within sixty (60) days.
