10.Lessee’s Option to Extend

 

Lessee, provided it is not then in default after notice and the expiration of any applicable grace or cure periods, and further provided it shall not have defaulted beyond any applicable notice, grace and cure periods during the remaining Lease Term after execution of this Sixth Lease Amendment, shall have the option to further extend the Term of this Lease beyond the 2021 Termination Date, as to the then entire Existing Leased Premises (as it may be supplemented by the exercise of Lessee’s rights under Section 9 hereof), on the terms and conditions set forth herein (the “2021 Extension Option”). 

 

The extension shall be for one (1) additional period of sixty (60) months (herein, the “2026 Extension Period”) at the then current Market Rent as contemplated below.

 

 

The 2021 Extension Option must be exercised by Lessee by notice in writing to the Lessor, prior to March 31, 2020, time being of the essence.  Once so exercised, the option to extend is irrevocable, notwithstanding the later determination of Market Rent as contemplated below.

 

“Market Rent” as used herein, shall be that rent charged for comparable research laboratory and office space of similar age and condition in laboratory buildings in the mid-Cambridge submarket as of the commencement of applicable lease period (including annual escalations thereon for each year based on increases in the Consumer Price Index or fixed increases, as the case may be, as determined by then prevailing market forces). 

 

If, after good faith attempts the Lessor and Lessee cannot agree on a figure representing Market Rent for the applicable space and lease timeframe, then either party, upon written notice to the other, may request appraisal and arbitration of the issue as provided in this Section.  Within fourteen (14) days of the request for appraisal, each party shall submit to the other the name of one unrelated individual or entity with proven expertise in the leasing of commercial real estate in greater Boston/Cambridge to serve as that party’s appraiser.  Each appraiser shall be paid by the party selecting him or it.  The two appraisers shall each submit their final reports to the parties within thirty (30) days of their selection making their determination as to Market Rent; however, in no event shall Market Rent be determined to be less than the Annual Base Rent as in effect as of the final year of the Term (i.e. as of the 2021 Termination Date).    The two appraisers shall meet within the next fourteen (14) days to reconcile their reports and collaboratively determine the Market Rent.  They shall each make their determination in writing (subject however, to the Applicable Rent Floor), including a statement if such is the case, that they are at an impasse.  Such a statement of impasse shall be submitted to the parties along with the Market Rent figure which each appraiser has selected and his reasons and substantiation therefor.  The appraisers, in case of an impasse, shall also agree on one unrelated individual or entity with expertise in commercial real estate in greater Boston, who shall evaluate the reports of the two original appraisers and within fourteen (14) days of submission of the issue to him, make his own determination as to a figure representing Market Rent (subject however, to the Applicable Rent Floor).  The determination of this individual or entity (i.e. arbitrator) absent, fraud, bias or undue prejudice shall be binding upon the parties. 

 

Lessee, in addition to the sums payable annually to Lessor as Annual Base Rent, shall pay to Lessor for each year of the 2021 Extension Period Lessee’s Allocable Percentage (as determined by the approximate total rentable space so leased) for Operating Expenses, Real Estate Taxes and utilities, as contemplated in the Lease. 

 

Annual Base Rent and Additional Rent shall be payable in advance, in equal monthly installments on the first day of each calendar month.

 

11.Subordination

 

The Lease as amended hereby shall be subject and subordinate to the lien of any and all mortgages and related documents placed on the Building, Leased Premises or the real property in

existence as of the date hereof or coming into existence at any time hereafter, without necessity for any confirming documentation.   Lessee shall use commercially reasonable efforts (which shall not be deemed to include the payment or expenditure of any sums whatsoever) to obtain a Subordination, Non-Disturbance and Attornment Agreement from its present and future mortgagees, in form and substance set forth in the Fourth Lease Amendment; but Lessor shall not be liable to Lessee in any manner (nor shall any of Lessee’s full and timely performance under this Lease be conditioned, waived, excused or altered in any manner whatsoever) if no SNDA is forthcoming, or if any of the terms and conditions of the same are not deemed acceptable.  This provision supersedes any contrary provisions of the Existing Lease.

 

12.Integration of Documents; Supremacy; Miscellaneous

 

This Sixth Lease Amendment contains the full understanding and agreement between the parties.  The parties hereto intend that this Sixth Lease Amendment operates to amend and modify the Existing Lease, and that those two documents shall be interpreted conjunctively; with any express conflict between the two to be resolved in favor of the stated terms of this Sixth Lease Amendment.  Except as modified hereby, all other terms and conditions of the Existing Lease shall remain unchanged and enforceable in a manner consistent with this Sixth Lease Amendment. 

 

This Agreement shall be governed by the laws of the Commonwealth of Massachusetts.  Any provisions deemed unenforceable shall be severable, and the remainder of this Sixth Lease Amendment and the Existing Lease shall be enforceable in accordance with their terms.

 

Time is of the essence with respect to all deadlines and other provisions of this Sixth Lease Amendment.
