Tenant shall have 1 right (the “Extension Right”) to extend the term of this Lease for 3 years (the “Extension Term”) on the same terms and conditions as this Lease (other than with respect to Base Rent and the Work Letter) by giving Landlord written notice of its election to exercise each Extension Right at least 9 months prior to the expiration of the Base Term of the Lease.

Extension Right. Section 39 of the Lease is hereby deleted and replaced in its entirety with the following:

Extension Request. The Borrower shall provide the applicable Extension Request at least three (3) Business Days prior to the date on which ​ under the Existing Term Loan Tranche or Existing Revolver Tranche, as applicable, are requested to respond, and shall agree to such procedures, if any, as may be established by, or acceptable to, the Administrative Agent, in each case acting reasonably to accomplish the purposes of this ‎Section 2.16. No Lender shall have any obligation to agree to have any of its Term Loans of any Existing Term Loan Tranche amended into Extending Term Loans or any of its Revolving Credit Commitments amended into Extending Revolving Credit Commitments, as applicable, pursuant to any Extension Request. Any Lender holding a Loan under an Existing Term Loan Tranche (each, an “Extending Term Lender”) wishing to have all or a portion of its Term Loans under the Existing Term Loan Tranche subject to such Extension Request amended into Extending Term Loans and any Revolving Credit Lender (each, an “Extending Revolving Credit Lender”) wishing to have all or a portion of its Revolving Credit Commitments under the Existing Revolver Tranche subject to such Extension Request amended into Extending Revolving Credit Commitments, as applicable, shall notify the Administrative Agent (each, an “Extension Election”) on or prior to the date specified in such Extension Request of the amount of its Term Loans under the Existing Term Loan Tranche or Revolving Credit Commitments under the Existing Revolver Tranche, as applicable, which it has elected to request be amended into Extending Term Loans or Extending Revolving Credit Commitments, as applicable (subject to any minimum denomination requirements imposed by the Administrative Agent). In the event that the aggregate principal amount of Term Loans under the Existing Term Loan Tranche or Revolving Credit Commitments under the Existing Revolver Tranche, as applicable, in respect of which applicable Term ​ or Revolving Credit ​, as the case may be, shall have accepted the relevant Extension Request exceeds the amount of Extending Term Loans or Extending Revolving Credit Commitments, as applicable, requested to be extended pursuant to the Extension Request, Term Loans or Revolving Credit Commitments, as applicable, subject to Extension Elections shall be amended to Extending Term Loans or Revolving Credit Commitments, as applicable, on a pro rata basis (subject to rounding by the Administrative Agent, which shall be conclusive) based on the aggregate principal amount of Term Loans or Revolving Credit Commitments, as applicable, included in each such Extension Election.

Extension Amendment. Extended Revolving Credit Commitments and New Revolving Credit Commitments shall be established pursuant to an amendment (each, an “Extension Amendment”) to this Agreement among the ​, the [[Administrative Agent:Organization]] and each Extending Revolving Credit Lender and each New Revolving Commitment Lender, if any, providing an Extended Revolving Credit Commitment or a New Revolving Credit Commitment, as applicable, thereunder, which shall be consistent with the provisions set forth in Sections 2.17(a, (b)) and # above (but which shall not require the consent of any other Lender). The effectiveness of any Extension Amendment shall be subject to the satisfaction on the date thereof of each of the conditions set forth in [Sections 4.2(a) and (b)])] and, to the extent reasonably requested by the [[Administrative Agent:Organization]], receipt by the [[Administrative Agent:Organization]] of # legal opinions, board resolutions and officers’ certificates consistent with those delivered on the Effective Date other than changes to such legal opinion resulting from a Change in Law, change in fact or change to counsel’s form of opinion reasonably satisfactory to the [[Administrative Agent:Organization]] and # reaffirmation agreements and/or such amendments to the Collateral Documents as may be reasonably requested by the Collateral Agent in order to ensure that the Extended Revolving Credit Commitments or the New Revolving Credit Commitments, as the case may be, are provided with the benefit of the applicable Loan Documents. The [[Administrative Agent:Organization]] shall promptly notify each Lender as to the effectiveness of each Extension Amendment. Each of the parties hereto hereby agrees that this Agreement and the other Loan Documents may be amended pursuant to an Extension Amendment, without the consent of any other Lenders, to the extent (but only to the extent) necessary to # reflect the existence and terms of the Extended Revolving Credit Commitments or the New Revolving Credit Commitments, as the case may be, incurred pursuant thereto, # make such other changes to this Agreement and the other Loan Documents (without the consent of the Requisite Lenders) and # effect such other amendments to this Agreement and the other Loan Documents as may be necessary or appropriate, in the reasonable opinion of the [[Administrative Agent:Organization]] and the ​, to effect the provisions of this Section, and the Requisite Lenders hereby expressly authorize the [[Administrative Agent:Organization]] to enter into any such Extension Amendment.

Extension; Waiver. Subject to Section 7.01, at any time prior to the Effective Time of the Acquisition, the parties may # extend the time for the performance of any of the obligations or other acts of the other parties, # waive any inaccuracies in the representations and warranties contained in this Agreement or in any document delivered pursuant to this Agreement, or # waive compliance with any of the agreements or conditions contained in this Agreement. Any agreement on the part of a party to any such extension or waiver shall be valid only if set forth in an instrument in writing signed on behalf of such party. 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.

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.
