“If during the calendar year for which Operating Costs, including Base Operating Costs, are being computed, the Building was not fully occupied by tenants, or if Landlord was not supplying all tenants with the services, amenities or benefits being supplied hereunder, the categories of Operating Costs which vary with occupancy shall be reasonably extrapolated by Landlord to the estimated Operating Costs that would have been incurred if the Building were fully occupied by tenants, or if such services were being supplied to all tenants, and such extrapolated amount shall, for the purposes of this Section 4.2.3, be deemed to be the Base Operating Costs.”

7.As of July 1, 2020, the Base Taxes specified in Section 1.1 of the Lease shall be changed to Taxes during the Town of Burlington’s fiscal tax year 2021 (i.e., July 1, 2020 - June 30, 2021).

(A)All work that is deemed necessary or desirable by Tenant to prepare the Premises for Tenant's continued use and occupancy shall be performed by Tenant, at its expense, and in accordance with plans and specifications approved in advance by Landlord, which approval shall be requested, granted and/or withheld all in accordance with Section 6.2.5 of the Lease (such approved work is referred to herein as "Tenant's Work"). All contractors, subcontractors, architects, engineers and project managers selected by Tenant for the performance of Tenant's Work shall first be approved by Landlord, such approval not to be

unreasonably withheld, conditioned or delayed. Tenant agrees to employ for the Tenant’s Work a general contractor reasonably approved by Landlord in accordance with the preceding sentence. Tenant or Tenant’s general contractor shall maintain “builder’s risk” insurance covering Landlord and Tenant as their interests may appear, against loss or damage by fire, vandalism, malicious mischief and such risks as are customarily covered by a so-called Special Risk Policy to the full completed value of the Tenant’s Work. Tenant or its contractors shall submit certificates evidencing such coverage to Landlord prior to the commencement of any component of Tenant’s Work. All Tenant's Work shall be performed in good and workmanlike manner in accordance with all building codes and requirements of the Town of Burlington and all applicable laws and regulations of other governmental authorities having jurisdiction, and in compliance with all requirements of Section 6.2.5 of the Lease, and Landlord’s Construction Rules and Regulations attached hereto as Exhibit A. Prior to applying for any building permit, Tenant shall submit to Landlord architectural, electrical and mechanical construction drawings, plans and specifications ("Tenant's Plans") necessary for the Tenant's Work. Tenant's Plans shall be prepared by an architectural and engineering firm selected by Tenant and all costs and expenses of preparing Tenant's Plans shall be Tenant's sole responsibility. The requirements, terms and limitations contained in said 6.2.5 shall govern all aspects of Tenant’s Work, including the process for submission and approval of the Tenant’s Plans, provided, however, that Landlord’s approval of any interior installations or alterations visible from outside the Premises may be granted or withheld in Landlord’s sole discretion. Tenant hereby acknowledges and agrees that Landlord's review of, and Landlord's granting of its approval to, any plans and specifications submitted to it under this Amendment shall not constitute or be deemed to constitute a judgment, representation or agreement by Landlord that such plans and specifications comply with the requirements of any legal authorities or that such plans and specifications will be approved by the Town of Burlington. Landlord shall not charge Tenant any fees for construction review or supervision performed by or on behalf of Landlord in connection with Tenant's Work, provided, however, if Tenant requests that Landlord perform construction supervision, Tenant shall pay a construction management fee to Landlord’s agent, Nordblom Management Company, in the amount of 3% of the hard construction costs of Tenant’s Work. Tenant shall pay any and all actual, out-of-pocket third party fees and expenses incurred by Landlord in connection with review of Tenant's Plans, as needed.

(B)Landlord shall provide Tenant with a tenant improvement allowance equal to $2,992,950.00 (the “TI Allowance”) to be used for paint, carpet and other general office leasehold improvements in the Premises. Tenant may apply up to $300,000.00 of the TI Allowance towards fixtures, furniture and equipment (the “Extended Term FF&E”). Following Landlord’s approval of Tenant’s general contractor and Tenant’s Plans, Tenant shall provide Landlord with a copy of the construction contract and its total budget for the hard and soft costs for the construction of the Tenant’s Work (the “Total Costs”). Tenant shall pay any and all costs associated with the Tenant’s Work which exceed the TI Allowance.

(C)If Landlord’s agent, Nordblom Management Company, is not selected by Tenant as the project manager for the Tenant’s Work, Landlord shall disburse the TI Allowance to Tenant in four (4) installments, as follows:

(i)Upon completion of thirty percent (30%) of the Tenant’s Work, Landlord shall disburse the first (1st) installment of the TI Allowance (the “First Installment”) in an amount up to twenty-five percent (25%) of the TI Allowance evidenced by paid invoices from Tenant’s general contractor and other direct contractors and subcontractors (“Paid Invoices”) providing servicers or supplying materials for the Tenant’s Work. Upon completion of sixty percent (60%) of the Tenant’s Work, Landlord shall disburse the second (2nd) installment of the TI Allowance (the “Second Installment”) in an amount up to an additional twenty-five percent (25%) of the TI Allowance evidenced by Paid Invoices. Upon completion of ninety percent (90%) of the Tenant’s Work, Landlord shall disburse the third (3^rd) installment of the TI

Allowance (the “Third Installment”) in an amount up to an additional forty percent (40%) of the TI Allowance evidenced by Paid Invoices, but in no event shall the sum of the First Installment plus the Second Installment plus the Third Installment be greater than $2,693,655.00. Each installment shall be payable within thirty (30) days after Landlord’s receipt of all of the following documentation relating to the installment for which disbursement is being requested, to Landlord’s reasonable satisfaction:

(a)a conditional lien waiver for the current requisition from Tenant’s general contractor, subcontractors and suppliers performing work or providing materials to date,

(b)a requisition for payment from Tenant’s architect in the form of AIA Document G702 for all work for which disbursement is being requisitioned,

(c)the submission by Tenant of a written statement from Tenant’s architect or engineer stating (a) whether there has been any change in the Total Costs (and if so, what the updated Total Costs are), and (b) that the Tenant’s Work for which payment is being requisitioned has been completed in accordance with the approved Tenant’s Plans,

(d)copies of paid invoices from Tenant’s general contractor evidencing such hard construction costs of the Tenant’s Work for which disbursement is being requisitioned; and, as applicable, copies of paid invoices from Tenant’s architects/engineers/project managers, and any other party providing services or supplying materials, evidencing the soft costs for which disbursement is being requested, and

(e)with respect to the Third Installment, unconditional lien waivers for past payments from Tenant’s general contractor and all subcontractors and suppliers,

(ii)Upon final completion of the Tenant’s Work, Landlord shall disburse the fourth (^4th) and final installment of the TI Allowance in an amount equal to the remaining ten percent (10%) of the TI Allowance which shall be payable to Tenant within thirty (30) days after Landlord’s receipt of all of the following documentation, to Landlord’s reasonable satisfaction:

(a)An unconditional final waiver of lien from Tenant’s general contractor and from all subcontractors and suppliers,

(b)one (1) set of “as-built” plans for the Tenant’s Work in CAD File and PDF format,

(c)the submission by Tenant of a written statement from Tenant’s architect or engineer stating that the Tenant’s Work for which payment is being requisitioned has been completed, substantially in accordance with the approved Tenant’s Plans,

(iii)copies of paid invoices from Tenant’s general contractor evidencing such costs of the Tenant’s Work for which disbursement is being requisitioned; and, as applicable, copies of paid invoices from Tenant’s architects/engineers/project managers, and any other party providing services or supplying materials, evidencing the costs for which disbursement is being requested, and a copy of the final (as opposed to temporary) certificate of occupancy for the Premises issued by the Town of Burlington.

(D)Any portion of the TI Allowance that is unused or unrequested by June 1, 2020 shall accrue to Landlord. If the final actual cost of Tenant’s Work shall be in excess of the TI Allowance, then the entire amount of such excess cost shall be paid solely by Tenant and Landlord shall be under no obligation to pay any such excess.

(E) If Tenant selects Nordblom Management Company to act as the project manager for Tenant’s Work, Landlord shall fund the Tenant’s Work, up to the TI Allowance, and shall cause the Tenant’s Work to be performed by a general contractor mutually acceptable to Landlord and Tenant, each acting reasonably. The mutually agreed upon general contractor is referred to in this Amendment as the “Approved General Contractor”. Following determination of the Approved General Contractor, Nordblom Management Company, acting as Landlord’s agent, shall execute an AIA construction contract with the Approved General Contractor. Upon Tenant’s approval of the total budget for the hard and soft costs of the Tenant’s Work, if it is determined that the approved total budget will exceed the TI Allowance, then Tenant shall pay all costs in excess of the TI Allowance (the “Excess Costs”) on a pari passu basis with Landlord. The amount Tenant is required to pay towards each invoice from the General Contractor shall be in the proportion by which the total costs of Tenant’s Work exceed the TI Allowance (by way of example of the foregoing only, if the total budget for the costs of Tenant’s Work is $3,500,000.00, then Landlord will fund 85.51% of each invoice from the General Contractor and Tenant will pay the remaining 14.49% of each such invoice). Tenant shall pay its share within thirty (30) days of Landlord’s written request, accompanied by a copy of the invoice for which payment is being made. The determination of the Excess Costs shall be adjusted from time to time for any change orders over the course of the construction of Tenant’s Work. Notwithstanding the foregoing, if Tenant is obligated to pay the Excess Costs pursuant to this subparagraph (E), then Tenant agrees that the TI Allowance will first be applied to payment of the hard construction costs of the Tenant’s Work and the remaining portion of the TI Allowance may be applied towards soft costs, subject to Tenant’s right to apply a portion of the TI Allowance towards any Extended Term FF&E.

(F)At the expiration or earlier termination of the Term, Landlord shall have the right to require all or any of the Extended Term FF&E to remain in the Premises, in Landlord’s sole discretion.

9.During the Extended Term, Tenant shall remain obligated to maintain a Letter of Credit in the amount of $699,395.00, pursuant to the requirements of Section 4.4 of the Lease, and shall, at its sole expense, take all steps necessary to amend the existing Letter of Credit such that its final expiration date shall be forty-five (45) days after the Expiration Date of the Lease, as extended by this Amendment. No later than thirty (30) days prior to the commencement of the Extended Term, Tenant shall deliver to Landlord a substitute or amended Letter of Credit that complies with the requirements of this paragraph and Section 4.4 of the Lease. As of the Effective Date, Section 4.4.9 of the Lease shall be deleted and of no further force or effect.

10.As of the Effective Date, (a) Tenant’s Extension Option under Section 2.3 of the Lease shall be deleted and of no further force or effect, and (b) the third paragraph of Section 2.1 with regard to parking is hereby deleted and the following is substituted in its place: “Tenant shall be permitted, on an unreserved first-come first served basis, to use up to 3.6 spaces per 1,000 rentable square feet of the Premises in the parking area serving the Building, or in a parking area reasonably proximate to the Building.

11.Reference is made to that certain lease between Landlord and Tenant dated November 9, 2009 (the “65 NWD Lease”), for premises at adjacent 65 Network Drive (the “65 NWD Premises”). The parties shall execute an amendment to the 65 NWD Lease simultaneously with this Amendment whereby Tenant shall surrender a portion of the premises under the 65 NWD Lease consisting of a portion of the first floor and the entire second floor of the 65 NWD Premises. On account of Tenant’s surrender of the second floor

of the 65 NWD Premises, the Connector Bridge between the 65 NWD Premises and the Premises will no longer provide access to the 65 NWD Premises, but will continue to provide access to the Premises from the exterior areas of the Building. Accordingly, effective as of the date of the amendment to the 65 NWD Lease), the Lease shall be amended as follows:

(A)Section 2.1 shall be amended by adding the following sentence to the end of the first paragraph: “Tenant shall have the non-exclusive right to use the Connector Bridge between 75 Network Drive and 65 Network Drive to access the Premises. For the avoidance of doubt, the right to use of the Connector Bridge is granted solely to Tenant and the tenant of the second floor of 65 Network Drive solely for access to each such tenant’s respective premises”;

(B)In Section 4.2.3, the paragraph that defines “Operating Costs” shall be amended by adding the phrase “which are equitably allocable to the Building” after the term “Connector Bridge” in each instance such term appears in said paragraph;

(C)In Section 5.9, the parenthetical phrase “(excluding the Connector Bridge)” shall be deleted therefrom.

(D)For the purposes of determining an equitable allocation to Tenant of costs associated with the Connector Bridge, such costs shall be shared between Tenant and the second floor tenant at 65 Network Drive proportionately based on the rentable square footage of each tenant’s premises.

12.To correct two scrivener’s errors, the Lease is amended as follows:

(A)Section 6.2.1 of the Lease is hereby modified by changing the reference to the “Building 75 Premises” contained in the third sentence of the first full paragraph of Section 6.2.1, to the “Building 65 Premises”; and

(B)The final two sentences of the first paragraph of Section 2.1 are deleted in their entirety and replaced with the following: The areas and facilities described in clauses (a) and (b) above are referred to as “Building Common Areas” and the areas, facilities, and amenities of the Park described in clause (c) above are referred to as “Campus Common Area.”

13.Tenant agrees to execute and deliver an amended notice of lease in the form attached hereto as Exhibit B, which Landlord shall record following the full execution and delivery of this Amendment. Further, Tenant agrees to execute, acknowledge and deliver a notice of termination of lease, in Tenant’s name, upon Tenant’s execution of this Amendment, in the form attached hereto as Exhibit C, which Landlord shall hold in escrow until the expiration or earlier termination of the Lease.

(A)Landlord hereby advises that one of the entities affiliated with Landlord is a collective investment fund (the "Fund") which holds the assets of one or more employee benefit plans or retirement arrangements which are subject to Title I of the Employee Retirement Income Security Act of 1974, as amended ("ERISA") and/or Section 4975 of the Internal Revenue Code of 1986, as amended (the "Code") (each a "Plan"), and with respect to which JPMorgan Chase Bank ("JPMCB") is the Trustee and that, as a result, Landlord may be prohibited by law from engaging in certain transactions.

(B)Landlord hereby represents and warrants to Tenant that, as of the date hereof, the only Plan whose assets are invested in the Fund which, together with the interests of any other Plans maintained

by the same employer or employee organization, represent a collective interest in the Fund in excess of ten percent (10%) of the total interests in the Fund (each, a "10% Plan") is “Strategic Property Fund” (collectively, the "Existing 10% Plan").

(C)Tenant represents and warrants that as of the date hereof, and at all times while it is a Tenant under this Lease, one of the following statements is, and will continue to be, true: (1) Tenant is not a "party in interest" (as defined in Section 3(14) of ERISA) or a "disqualified person" (as defined in Section 4975 of the Code) (each a "Party in Interest") with respect to the Existing 10% Plan or, (2) if Tenant is a Party in Interest, that: (A) neither Tenant nor its "affiliate" (as defined in Section V(c) of PTCE 84-14, "Affiliate") has, or during the immediately preceding one (1) year has, exercised the authority to either: (i) appoint or terminate JPMCB as the qualified professional asset manager (as defined in Section V(a) of PTCE 84-14, "QPAM") of any of the assets of the Existing 10% Plan with respect to which Tenant or its Affiliate is a Party in Interest; or (ii) negotiate the terms of the management agreement with JPMCB, including renewals or modifications thereof, on behalf of the Existing 10% Plan; and (B) neither Tenant nor any entity controlling, or controlled by, Tenant owns a five percent (5%) or more interest (within the meaning of PTCE 84-14, "5% Interest") in J.P. Morgan Chase & Co.

(D)In the event that Landlord or the Fund notifies Tenant in writing that a Plan other than the Existing 10% Plan may become a 10% Plan, Tenant will, within 10 days of such notification, inform the Fund in writing as to whether it can make the same representations which it made in subparagraph C of this Section 10.12 with respect to such prospective 10% Plan. Thereafter, if based on such representations made by Tenant such Plan becomes a 10% Plan, Tenant represents and warrants that, at all times during the period Tenant is a tenant under this Lease, one of the statements set forth in subparagraph (D) of this Paragraph 14 will be true with respect to such 10% Plan.
