Extension Rights. Tenant shall have 2 consecutive rights (each, an “Extension Right”) to extend the term of this Lease for 1 year each (each, an “Extension Term”) on the same terms and conditions as this Lease (other than with respect to Base Rent) by giving Landlord written notice of its election to exercise each Extension Right at least 6 months prior, and no earlier than 9 months prior, to the expiration of the Base Term of the Lease or the expiration of any prior Extension Term.

Extension. BRPA shall take all actions necessary to obtain the approval of the BRPA Stockholders to extend the deadline for BRPA to consummate its initial Business Combination beyond ​ to ​ (such extension, the “Extension”, and such approval of the BRPA Stockholders of the Extension, the “Extension Approval”).

Extension. Subtenant shall have the option to extend (the “Option”) the Term for an additional period of one (1) year (the “Extension Period”) upon all terms and conditions of the Sublease, except that Subtenant shall have no further right to extend the Term, and the Base Rent shall be increased to the amounts provided for herein. The Option may be exercised only by Subtenant giving Sublandlord irrevocable and unconditional written notice thereof no later than nine (9) months before the commencement of the Extension Period; provided, however, only if Sublandlord intends to occupy the Sublet Portion upon expiration of the initial Term of this Sublease, then Sublandlord may nullify Subtenant’s exercise of the Option by written notice given to Subtenant within thirty (30) days of Subtenant’s exercise of the Option. Said exercise shall, at Sublandlord’s election, be null and void if Subtenant is in default under the Sublease at the date of said notice or at any time thereafter and prior to commencement of the Extension Period. If Subtenant shall fail to exercise the Option in accordance with the terms hereof, said Option shall terminate and be null and void. If Sublandlord shall fail to nullify said exercise within the period set forth above, Sublandlord’s nullification right shall terminate and be null and void. Subtenant’s exercise of the Option shall not operate to cure any default by Subtenant of any of the terms or provisions in this Sublease, nor to extinguish or impair any rights or remedies of Sublandlord arising by virtue of such default. If the Sublease or Subtenant’s right to possession of the Sublet Portion shall terminate in any manner whatsoever before Subtenant shall exercise the Option, or before the commencement of the Extension Period, or if Subtenant shall have assigned the Sublease or subleased all or any portion of the Sublet Portion before Subtenant shall have exercised the Option, then immediately upon such termination, sublease or assignment, the Option shall simultaneously terminate and become null and void. If the Term of the Sublease shall terminate for any reason prior to the expiration of the initial Term, then the Option shall become null and void, whether or not it has been previously exercised. Time is of the essence of this provision. The Extension Period shall be upon all the same terms and conditions of the Sublease except the Base Rent for the Extension Period shall increase by two and fifty hundredths percent (2.50%) over Base Rent payable in the last month of the initial Term.

Extension. Each undersigned lender other than the lender listed on [Schedule I] hereto (such lender, the “Non-Extending Lender” and each other lender party hereto, an “Extending Lender” and together, the “Extending Lenders”) hereby agrees to amend the Credit Agreement to extend, effective on the Amendment Effective Date, the Termination Date under the Credit Agreement in respect of such Extending Lender’s Commitment for one year to December 7, 2023 and by their acceptance hereof the Borrowers hereby confirm that the conditions set forth in [Section 2.19(b)(i) and (ii)])] of the Credit Agreement are satisfied as to such extension. For the avoidance of doubt, the Termination Date under the Credit Agreement with respect to the Non-Extending Lender’s Commitment shall be the “Termination Date” under the Credit Agreement as in effect immediately prior to the Amendment Effective Date and the Non-Extending Lender is party to this Amendment solely for purposes of consenting to the amendments set forth in Section 3 below and not for purposes of this Section 2.

Extension Request. The ​ shall provide the applicable Extension Request at least ten (10) Business Days (or such shorter period as may be agreed by the [[Administrative Agent:Organization]]) prior to the date on which Lenders under the Existing Revolver Tranche are requested to respond, and shall agree to such procedures, if any, as may be established by, or acceptable to, the [[Administrative Agent:Organization]], in each case acting reasonably, to accomplish the purposes of this Section 2.17. No Lender shall have any obligation to agree to provide any Extended Revolving Credit Commitment pursuant to any Extension Request. 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 Extended Revolving Credit Commitments shall notify the [[Administrative Agent:Organization]] (each, an “Extension Election”) on or prior to the date specified in such Extension Request of the amount of its Revolving Credit Commitments under the Existing Revolver Tranche which it has elected to request be amended into Extended Revolving Credit Commitments (subject to any minimum denomination requirements imposed by the [[Administrative Agent:Organization]]). In the event that the aggregate principal amount of Revolving Credit Commitments under the Existing Revolver Tranche in respect of which applicable Revolving Credit Lenders shall have accepted the relevant Extension Request exceeds the amount of Extended Revolving Credit Commitments requested to be extended pursuant to the Extension Request, Revolving Credit Commitments subject to Extension Elections shall be amended to reflect allocations of the Extended Revolving Credit Commitments, which Extended Revolving Credit Commitments shall be allocated as agreed by [[Administrative Agent:Organization]] and the ​.

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 Amendment. Extended Term Loans shall be established pursuant to an amendment (each, an “Extension Amendment”) to this Agreement among the Borrower, the Administrative Agent and each Extending Term Lender providing an Extended Term Loan thereunder, which shall be consistent with the provisions set forth in [Section 2.14(a)] 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 [Section 4.02] and, to the extent reasonably requested by the Administrative Agent or the Required Lenders, receipt by the Administrative Agent of # legal opinions, board resolutions and officers’ certificates consistent with those delivered on the Closing Date, other than changes to such legal opinions resulting from a change in law, change in fact or change to counsel’s form of opinion reasonably satisfactory to the Administrative Agent and the Required Lenders, and # reaffirmation agreements and/or such amendments to the Collateral Documents as may be reasonably requested by the Administrative Agent or the Required Lenders in order to ensure that the Extended Term Loans are provided with the benefit of the applicable Loan Documents. The Administrative Agent 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 Term Loans incurred pursuant thereto, # modify the scheduled repayments set forth in Section 2.07 with respect to any Existing Term Loan Tranche subject to an Extension Election to reflect a reduction in the principal amount of the Term Loans thereunder in an amount equal to the aggregate principal amount of the Extended Term Loans amended pursuant to the applicable Extension (with such amount to be applied ratably to reduce scheduled repayments of such Term Loans required pursuant to Section 2.07), # modify the prepayments set forth in Section 2.05 to reflect the existence of the Extended Term Loans and the application of prepayments with respect thereto, # make such other changes to this Agreement and the other Loan Documents consistent with the provisions and intent of the second paragraph of [Section 10.01] (without the consent of the Required Lenders called for therein) 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, the Required Lenders and the Borrower, to effect the provisions of this [Section 2.14], and the Required Lenders hereby expressly authorize the Administrative Agent to enter into any such Extension Amendment.

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.
