AGREEMENT

NOW THEREFORE, in consideration of the mutual promises contained herein and other good a valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Landlord, Original Tenant and Assignee hereby agree as follows:

Recitals; Capitalized Terms. All of the foregoing Recitals are true and correct. Each capitalized term used but not otherwise defined herein shall have the meaning ascribed thereto in the Lease.

Ratification; Conflicts. Except as amended by this Fifth Amendment, the Lease shall remain unchanged and in full force and effect. All references to the “Lease” shall be deemed to be references to the Lease, as amended by this Fifth Amendment. In the event of any conflict between the terms or conditions of the Lease and those of this Fifth Amendment, the terms and conditions of this Fifth Amendment shall control.

Consent to Assignment.

(a)

Subject to the terms of this Fifth Amendment, Landlord hereby consents to the assignment of the Lease to Assignee. Notwithstanding the assignment of the Lease to Assignee (the “Assignment”) pursuant to the Assignment Agreement and Landlord’s consent thereto, Assignee shall not take possession of the Premises unless and until Landlord shall have received an insurance certificate from Assignee satisfying the requirements of the Lease and the Letter of Credit required pursuant to Section 7 of this Fifth Amendment. Landlord agrees that, solely for purposes of determining whether Tenant has satisfied the Leasing Threshold, the Assignment to Assignee shall not constitute an “assignment” that prevents Assignee, as Tenant, from satisfying the Leasing Threshold at the time such determination is being made, provided, however, the requirement to not have assigned the Lease (other than assignments permitted pursuant to Section 12.5 of the Lease) in order to satisfy the Leasing Threshold shall continue to apply to any future assignment (other than an assignment permitted pursuant to Section 12.5 of the Lease) after the Assignment.

(b)

Original Tenant and Assignee represent and warrant to Landlord that the copy of the Assignment Agreement attached hereto as Exhibit A is a true, correct and complete copy of the Assignment Agreement. Landlord neither approves nor disapproves of any specific term, condition or agreement contained in the Assignment Agreement, and the Assignment Agreement shall be subordinate and at all times subject to all of the covenants, agreements, terms, provisions and conditions contained in the Lease (as amended by this Fifth Amendment).

(c)

Assignee covenants and agrees that, commencing as of the Assignment Effective Date and except as otherwise expressly set forth in this Fifth Amendment, Assignee (i) assumes all duties, obligations, and responsibilities of the Tenant under the Lease which first arise or accrue on and after the Assignment Effective Date, and (ii) agrees to pay, perform, observe and discharge

ACTIVE/112977395.9

all of Tenant’s covenants, conditions and obligations under the Lease required to be paid, performed and observed on the part of the Tenant under the Lease and which first arise or accrue on and after the Assignment Effective Date; provided, however, that Assignee shall have no (x) duty, obligation or responsibility with respect to any obligations of Tenant under the Lease which accrued prior to the Assignment Effective Date, (y) obligation to make any payments of the Monthly Improvement Costs Payment under the Lease, and (z) obligation to pay the Annual Fixed Rent or the Additional Rent payable under Sections 6.2 and 7.5 of the Lease prior to the Rent Adjustment Date. Assignee shall be responsible to pay all utility charges payable under Section 5.2 of the Lease from and after the Assignment Effective Date.

(d)

Original Tenant shall remain obligated to (i) pay and perform all monetary and non-monetary obligations of Tenant under the Lease, including, without limitation, all indemnification obligations and the payment of all Annual Fixed Rent, the Monthly Improvement Costs Payment, utility charges and Additional Rent payable under the Lease through the date immediately prior to the Assignment Effective Date, and (ii) pay the Extended Rent Payment (as hereinafter defined).

(e)

Except as otherwise expressly provided herein, nothing contained herein shall be construed to modify, waive, impair, or affect any of the terms, covenants or conditions contained in the Lease (including Assignee’s obligation to obtain any required consents for any other or future assignments or sublettings), or to waive any breach thereof, or any rights or remedies of Landlord under the Lease against any person, firm, association or corporation liable for the performance thereof, or to enlarge, increase, decrease, reduce or otherwise affect Landlord’s obligations or liabilities under the Lease, and all terms, covenants and conditions of the Lease are hereby declared by each of Landlord, Original Tenant and Assignee to be in full force and effect. Notwithstanding the foregoing, but provided and only so long as Original Tenant has (i) vacated and surrendered possession of the Premises in the Surrender Condition by the Surrender Date, as such terms are hereinafter defined, and (ii) paid the Extended Rent Payment by the Extended Rent Payment Date, as hereinafter defined (the “Release Conditions”), Original Tenant shall be released from all of the obligations and liabilities of Tenant under the Lease and Guarantor shall be released from all of the obligations and liabilities of Guarantor under the Guaranty (including, without limitation, the Annual Fixed Rent and Additional Rent obligations) that first accrue after the Assignment Effective Date. If Original Tenant does not timely satisfy the Release Conditions, then Original Tenant (and Guarantor) shall continue to be liable under the Lease and the Guaranty, respectively, for obligations accruing under the Lease through and including the date that the Release Conditions are satisfied (the “Subsequent Release Date”), except that, Tenant’s (and Guarantor’s) continuing liability for the payment of the Annual Fixed Rent under the Lease from the Assignment Effective Date through the Subsequent Release Date will be limited to the Annual Fixed Rent plus Additional Rent that would have been payable under the Lease during such extended liability period without giving effect to the increase in Annual Fixed Rent set forth in Section 6 of this Fifth Amendment. Notwithstanding the foregoing, Original Tenant’s obligations under the indemnification provisions in the Lease shall survive the Assignment Effective Date (or any Subsequent Release Date) as to any claims arising out of occurrences within the scope of the Lease’s indemnification provisions occurring prior to the Assignment Effective Date (or any Subsequent Release Date), whether or not the claims are asserted before, on or after the Assignment Effective Date (or any Subsequent Release Date).

ACTIVE/112977395.9

(f)

In consideration of this Fifth Amendment and the release of Original Tenant and Guarantor set forth in Section 3(e) above and notwithstanding that Original Tenant is obligated to vacate and surrender possession of the Premises at the time and in accordance with the terms of Section 4 of this Fifth Amendment, Original Tenant shall remain obligated to pay (and shall pay) to Landlord, by not later than March 25, 2022 (the “Extended Rent Payment Date”), the sum of $1,316,737.00 (the “Extended Rent Payment”) which represents the Annual Fixed Rent, Monthly Improvement Costs Payment, and the Additional Rent payable under Section 6.2 and Section 7.5 of the Lease for the three (3) months following the Assignment Effective Date (the “Extended Rent Period”). The obligation to make payments of the Monthly Improvement Costs Payment under the Lease shall terminate on the later date to occur of (i) the expiration of the Extended Rent Period, and (ii) the date Tenant satisfies the Release Conditions. Assignee shall be responsible for the payment of all other Additional Rent payable under the Lease from and after the Assignment Effective Date (including during the Extended Rent Period), such as, but without limitation, utility charges and overtime HVAC requested by Assignee.

Surrender of Possession. Original Tenant shall vacate and surrender possession of the Premises on or before March 31, 2022 (the “Surrender Date”) in the condition required under the Lease and this Fifth Amendment for surrender of the Premises at the expiration or earlier termination of the Lease Term, except that Original Tenant shall surrender the Premises to Assignee with the Purchased FF&E (as defined in the Assignment Agreement) and all alterations and other leasehold improvements in the Premises as of the Assignment Effective Date in its current AS IS condition, subject to normal wear and tear and to the provisions of Article XIV of the Lease (Fire, Casualty and Taking) in respect of any fire, casualty or taking occurring on or prior to the Assignment Effective Date. The Premises shall be delivered on the Surrender Date broom clean and free of all furniture, trade fixtures, equipment and other personal property of Tenant or anyone claiming by, through or under Tenant except for the Purchased FF&E. In the event of any fire or casualty to the Premises occurring prior to the Assignment Effective Date, Original Tenant shall be obligated to comply with its obligation, as tenant, under Section 14.1 of the Lease to pay over any insurance proceeds to Landlord with respect to alterations, additions or improvements within the Premises, which obligation shall survive the Assignment Effective Date and any release of Original Tenant under Section 3(e) of this Fifth Amendment. Notwithstanding the foregoing, Landlord agrees that neither Original Tenant nor Assignee shall be required to remove at any time any of the alterations and other leasehold improvements existing in the Premises or the Building (if installed by or on behalf of Original Tenant) as of the Effective Date of this Fifth Amendment, except that (y) Assignee (but not Original Tenant) shall be responsible to remove from the Premises, at Assignee’s expense, the Tenant’s Property (including the Purchased FF&E) from the Premises whether existing as of the Assignment Effective Date or thereafter installed by Tenant at the expiration or earlier termination of the Lease Term, and (z) Landlord reserves the right under Section 9.8(N) to require that Assignee remove the Emergency Generator and Generator Connections at the end of the Term. The condition in which Tenant is obligated to surrender possession of the Premises to Assignee under this Section 4 is referred to herein as the “Surrender Condition.”

If Original Tenant fails to vacate and surrender possession of the Premises in the condition required under this Fifth Amendment on the Surrender Date (a “Holdover Event”), Original Tenant expressly agrees that such failure shall, because of the Assignment and notwithstanding the

ACTIVE/112977395.9

Expiration Date of the Lease, constitute a holding over in the Premises and an immediate Event of Default under the Lease (without any notice or cure period applicable thereto) and, notwithstanding the provisions of Section 16.18 of the Lease to the contrary, the holdover amounts payable under Section 16.18 shall become payable by Original Tenant on a monthly basis (and not on a daily basis) for each month or part thereof that Original Tenant remains in possession of the Premises beyond the Surrender Date. If there is a Holdover Event, Landlord, at Landlord’s sole cost and expense, shall have the right to take all necessary and appropriate action to evict Original Tenant from the Premises by summary dispossess proceeding, judgment for possession or as otherwise provided by applicable law. Assignee agrees to cooperate with Landlord, at no cost to Assignee, in any such summary process action undertaken by Landlord against Original Tenant.

Primary Premises and Storage Premises. From and after July 1, 2022 (the “Rent Adjustment Date”), the Primary Premises shall be amended to contain 120,681 square feet of occupied space (and the Rentable Floor Area of the Premises will be amended to mean 120,681 square feet) and all references to the Storage Space shall be deleted and of no further force and effect. In furtherance thereof, effective as of the Rent Adjustment Date, Section 2.1.1 of the Lease shall be deleted from the Lease and the following definitions set forth in Section 1.2 of the Lease are hereby amended as follows:


Premises:	The entire interior rentable area of the Building which includes 120,681 square feet of occupied space (the “Primary Premises”), all as shown on the floor plans annexed hereto as Exhibit D and incorporated herein by reference.
Rentable Floor Area of the Premises:	120,681 square feet.

(b)

Assignee, as Tenant, shall continue to pay all other Additional Rent due under and pursuant to the terms of the Lease for the remainder of the Lease Term.

Letter of Credit. Not later than the date that is thirty (30) days following the Effective Date of this Fifth Amendment, Assignee shall pay to Landlord a security deposit in the amount of Eight Hundred Four Thousand Five Hundred Forty and 00/100 Dollars ($804,540.00) and Landlord shall hold the same, throughout the Lease Term (as it may be extended), as security for the performance by Tenant of all obligations on the part of Tenant to be performed under the Lease. Such security deposit shall be in the form of an irrevocable, unconditional, negotiable letter of

ACTIVE/112977395.9

credit (the “Letter of Credit”) which shall be governed by the terms and conditions set forth on Exhibit B attached hereto. If, on or after, July 1, 2027 (the “Reduction Review Date”), Tenant satisfies the Reduction Condition, as hereinafter defined, then, upon written request of Tenant, the amount of the Letter of Credit shall be reduced to Four Hundred Two Thousand Two Hundred Seventy and 00/100 Dollars ($402,270.00) (the “Reduced Letter of Credit Amount”) for the remainder of the Term, as it may be extended. If Tenant has satisfied the Reduction Condition as of the Reduction Review Date, Landlord shall, at Tenant’s election and within ten (10) business days after Landlord’s receipt of written request from Tenant, cooperate to accomplish the reduction of the Letter of Credit to the Reduced Letter of Credit Amount by either accepting an amendment to the Letter of Credit which Landlord is then holding (which amendment shall be in form and substance reasonably acceptable to Landlord) or by exchanging the Letter of Credit which Landlord is then holding for a substitute Letter of Credit complying with the requirements of this Section 7 and Exhibit B attached hereto in the appropriate amount. In no event shall the Letter of Credit have automatic reduction provisions. The “Reduction Condition” shall mean that there is no monetary or material non-monetary Event of Default by Tenant then in existence and there has not been any monetary or material non-monetary Event of Default by Tenant at any time within the twenty-four (24) months immediately preceding the Reduction Review Date.

The provisions of this Section 7 shall apply to Assignee (and any successor or assign of Assignee) but shall not apply to Original Tenant.

(a) Without limitation of Landlord’s, Overlandlord’s and/or Master Developer’s express rights under Section 2.1 of the Lease to construct Additional Improvements at the Complex, Overlandlord may, in connection with Overlandlord’s development of the Complex, determine to establish a condominium for some or all of the Complex, including the Building and the Property.

ACTIVE/112977395.9

Landlord, terminate the ▇▇▇▇▇▇▇▇▇ and the ▇▇▇▇▇▇▇▇▇ SNDA. The Lease shall be subject and subordinate to any such A&R Declaration so long as such A&R Declaration does not have a Tenant Adverse Impact. From and after the date that the A&R Declaration is executed and recorded with the Registry, (w) the A&R Declaration will apply to and govern only the Phase 1 Site (as defined in the A&R Declaration) and not the remainder of the Master Site, (x) all references in the Lease to the Declaration shall mean and refer to the A&R Declaration, as the same may be amended from time to time subject to and in accordance with the applicable provisions of the Lease, (y) all references in the Lease to the Common Elements shall mean and refer to both the general common elements established under the Condominium Documents and the Common Infrastructure described in the A&R Declaration, and (z) the Declaration Common Expenses in the Lease shall mean and refer to both the Common Expenses allocated to the Office Condo Unit pursuant to the A&R Declaration and the common expenses assessed to the Office Condo Unit under the Condominium Documents, provided, however, that the allocation of expenses to the Office Condo Unit pursuant the A&R Declaration and the Condominium Documents, respectively, shall not exceed, in the aggregate, the allocation of such expenses permitted under the Declaration but for the execution and recording of the A&R Declaration and Condominium Documents.

Extension Rights; Expansion Rights. From and after the Effective Date of this Fifth Amendment, Tenant’s rights to extend the Lease Term and to expand the Premises shall terminate and Sections 3.2 and Article XVIII are hereby deleted and of no further force or effect.

Letter of Credit Terms and Conditions

The Letter of Credit shall (i) be issued by and drawn on a bank reasonably approved by Landlord and at a minimum having a long term issuer credit rating from Standard and Poor’s Professional Rating Service of A or a comparable rating from ▇▇▇▇▇’▇ Professional Rating Service, (ii) be substantially in the form attached hereto as Exhibit C or such other form reasonably approved by Landlord, (iii) permit one or more draws thereunder to be made accompanied only by certification by Landlord or Landlord’s managing agent that pursuant to the terms of the Lease, Landlord is entitled to draw upon such Letter of Credit, (iv) permit transfers at any time without charge, (v) permit presentment in Boston, Massachusetts and (vi) provide that any notices to Landlord be sent to the notice address provided for Landlord in the Lease. If the credit rating for the issuer of such Letter of Credit falls below the standard set forth in (i) above or if the financial condition of such issuer changes in any other material adverse way or if any trustee, receiver or liquidator shall be appointed for the issuer, Landlord shall have the right to require that Tenant provide a substitute letter of credit that complies in all respects with the requirements of this Exhibit A, and Tenant’s failure to provide the same within thirty (30) days following Landlord’s written demand therefor shall entitle Landlord to immediately draw upon the Letter of Credit. Any such Letter of Credit shall be for a term of two (2) years (or for one (1) year if the issuer thereof regularly and customarily only issues letters of credit for a maximum term of one (1) year) and shall in either case provide for automatic renewals through the date which is ninety (90) days subsequent to the scheduled expiration of the Lease Term (as the same may be extended) or if the issuer will not grant automatic renewals, the Letter of Credit shall be renewed by Tenant each year and each such renewal shall be delivered to and received by Landlord not later than thirty (30) days before the expiration of the then current Letter of Credit (herein called a “Renewal Presentation Date”). In the event of a failure to so deliver any such renewal Letter of Credit on or before the applicable Renewal Presentation Date (including, without limitation, in the event of a notice of non-renewal from the issuer), Landlord shall be entitled to present the then existing Letter of Credit for payment and to receive the proceeds thereof, which proceeds shall be held as Tenant’s security deposit, subject to the terms of this Exhibit A. Any failure or refusal of the issuer to honor the Letter of Credit shall be at Tenant’s sole risk and shall not relieve Tenant of its obligations hereunder with regard to the security deposit. Upon the occurrence of any default of Tenant, Landlord shall have the right from time to time without prejudice to any other remedy Landlord may have on account thereof, to draw on all or any portion of such deposit held as a Letter of Credit and to apply the proceeds of such Letter of Credit or any cash held as such deposit, or any part thereof, to Landlord’s damages arising from such default on the part of Tenant under the terms of the Lease. If Landlord so applies all or any portion of such deposit, Tenant shall within seven (7) days after notice from Landlord deposit cash with Landlord in an amount sufficient to restore such deposit to the full amount stated in Section 8 of this Fifth Amendment. While Landlord holds any cash deposit Landlord shall have no obligation to pay interest on the same and shall have the right to commingle the same with Landlord’s other funds. Neither the holder of a mortgage nor the lessor in a ground lease on property which includes the Premises shall ever be responsible to Tenant for the return or application of any such deposit, whether or not it succeeds to the position of Landlord hereunder, unless such deposit shall have been received in hand by such holder or ground lessor.

Tenant not then being in default and having performed all of its obligations under this Lease, including the payment of all outstanding Annual Fixed Rent and Additional Rent, Landlord shall return the deposit, or so much thereof as shall not have theretofore been applied in accordance with the terms of this Exhibit A, to Tenant on the expiration or earlier termination of the Lease Term (as the same may have been extended) and surrender possession of the Premises by Tenant to Landlord in the condition required in the Lease at such time.

You shall have the right to make partial draws against this Letter of Credit from time to time.

This Letter of Credit is transferable in its entirety to any successor in interest to Beneficiary as owner of [Property, Address, City/Town, State]. Should a transfer be desired, such transfer will be subject to the return to us of this advice, together with written instructions. Any fees related to such transfer shall be for the account of the Applicant.

least sixty (60) days prior to any such date of expiration, the undersigned shall give written notice to Beneficiary, by certified mail, return receipt requested and at the address set forth above or at such other address as may be given to the undersigned by Beneficiary, that this Letter of Credit will not be renewed.

If any instructions accompanying a drawing under this Letter of Credit request that payment is to be made by transfer to your account with another bank, we will only effect such payment by fed wire to a U.S. regulated bank, and we and/or such other bank may rely on an account number specified in such instructions even if the number identifies a person or entity different from the intended payee.

This Letter of Credit is governed by the Uniform Customs and Practice for Documentary Credits (1993 Revision), International Chamber of Commerce Publication 500.

Very truly yours,
