Extension; Waiver. At any time prior to the Effective Time, the parties hereto, may, # by action taken or authorized by the ​ Board and approved by the Bank, extend the time for the performance of any of the obligations or other acts of the other parties hereto, # waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto and # waive compliance with any of the agreements or conditions contained herein. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such party. Such extension or waiver shall not be deemed to apply to any time for performance, inaccuracy in any representation or warranty, or noncompliance with any agreement or condition, as the case may be, other than that which is specified in the extension or waiver. The failure of any party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights, nor shall any single or partial exercise of any such right, or any abandonment or discontinuance of steps to enforce such right, or any course of conduct, preclude any other or further exercise thereof or the exercise of any other right. The rights and remedies of the parties hereunder are cumulative and are not exclusive of any rights or remedies which they would otherwise have hereunder.

Extension Offers. Pursuant to one or more offers (each, an “Extension Offer”) made from time to time by the Borrowers to all Lenders of Loans with a like Maturity Date, the Borrowers may extend the Maturity Date of each such Lender’s Revolving Facility Commitments and, subject to Section 2.22(3)(b), otherwise modify the terms of such Revolving Facility Commitments pursuant to the terms of the relevant Extension Offer, including by increasing the interest rate or fees payable in respect to such Revolving Facility Commitments (each, an “Extension,” and each group of Revolving Facility Commitments so extended, as well as the original Revolving Facility Commitments not so extended, being a “tranche”). Each Extension Offer will specify the minimum amount of Revolving Facility Commitments with respect to which an Extension Offer may be accepted, which will be an integral multiple of $1.0 million and an aggregate principal amount that is not less than $25.0 million (or # if less, the aggregate principal amount of such Revolving Facility Commitments or # such lesser minimum amount as is approved by the Administrative Agent, such consent not to be unreasonably withheld, conditioned or delayed), and shall be offered on a pro rata basis to all Lenders having Revolving Facility Commitments with a like Maturity Date. If the aggregate outstanding principal amount of Loans and Revolving Facility Commitments (calculated on the face amount thereof) in respect of which Lenders have accepted an Extension Offer exceeds the maximum aggregate principal amount of Loans and Revolving Facility Commitments offered to be extended pursuant to an Extension Offer, then the Loans and Revolving Facility Commitments of such Lenders will be extended ratably up to such maximum amount based on the Revolving Facility Commitments of the Lenders that have accepted such Extension Offer. There is no requirement that any Extension Offer or Extension Amendment (defined as follows) be subject to any “most favored nation” pricing provisions. Each Lender accepting an Extension Offer is referred to herein as an “Extending Lender,” and the Loans and Revolving Facility Commitment held by such Lender (and so extended) accepting an Extension Offer are referred to herein as “Extended Loans” and “Extended Commitments”.

Extension Amendments. The Lenders hereby irrevocably authorize the Administrative Agent to enter into amendments to this Agreement and the other Loan Documents (an “Extension Amendment”) with the Borrowers as may be necessary in order to establish new tranches in respect of Extended Commitments (and related Extended Loans) and such technical amendments as may be necessary or appropriate in the reasonable opinion of the Administrative Agent and the Borrowers in connection with the establishment of such new tranches, in each case, on terms consistent with this Section 2.22. This Section 2.22 supersedes any provisions in Section 10.08 to the contrary. Except as otherwise set forth in an Extension Offer, there will be no conditions to the effectiveness of an Extension Amendment. Extensions will not constitute a voluntary or mandatory payment or prepayment for purposes of this Agreement.

Extension Terms. All terms and conditions of this Lease shall be applicable during the Extension Period(s) except that the amount of Base Rent charged for the Renewal Period shall be the then “Prevailing Market Rent”, which shall be the base or fixed rent for comparable office space in the Seaport District of the City of Boston being leased to renewal tenants in comparable buildings, taking into account all then-relevant factors, including such market concessions, if any, as are then being offered by landlords to renewal tenants leasing comparable office space in comparable buildings, including the existence or nonexistence of any rent abatement, the amount of any tenant improvement allowance, the amount of any brokerage commissions, the net or gross basis of the comparable leases as opposed to the net lease structure of this Lease. If within thirty (30) days following delivery of an Extension Election Notice, Landlord and Tenant have not mutually agreed on the Prevailing Market Rent for the applicable Extension Period, then the parties shall use the following method to determine the Prevailing Market Rent (the “Baseball Arbitration Method”): within ten (10) business days after the expiration of such thirty-day period, an impartial, senior broker in a Boston, Massachusetts leasing brokerage firm (the “Baseball Arbitrator”) shall be selected jointly by Landlord and Tenant. If Landlord and Tenant cannot not agree upon the Baseball Arbitrator, then the same shall be designated by the then president of the Commercial Brokers Association of the Greater Boston Real Estate Board (or comparable organization reasonably satisfactory to the parties, if no longer existing), who may not select himself or herself or a broker at the same firm with which he or she is then affiliated. The Baseball Arbitrator selected by the parties or designated as aforesaid shall have at least ten (10) years’ experience in the leasing of first-class office space in downtown Boston (including the Seaport and Financial District submarkets) and shall not have worked for either party in the five (5) years prior to his or her selection. Landlord and Tenant shall each submit to the Baseball Arbitrator and to the other their respective proposed Prevailing Market Rent for the Premises within ten (10) days after the designation of such Baseball Arbitrator. The Baseball Arbitrator may not select any other rental value for the Premises, other than one submitted by Landlord or Tenant. The determination of the Baseball Arbitrator so-selected or designated shall be binding upon Landlord and Tenant shall serve as the basis for the determination of the annual Base Rent payable for the respective Extension Period. Each party shall pay one-half of the cost of the Baseball Arbitrator. Each Baseball Arbitrator shall thereupon make his or her determination of the Prevailing Market Rent within twenty (20) business days after the appointment of such Baseball Arbitrator.

Each Lender may, in its sole discretion, agree to any Extension Request. Each Lender that agrees to an Extension Request by the date falling 15 days before the relevant anniversary of the date of this Agreement will extend its Commitment for a further period of one year or two years, as set out in the relevant Extension Request, from the then current Final Maturity Date in respect of that Lender's Commitment and the Final Maturity Date with respect to the Commitment of that Lender will be extended accordingly.
