{B1878467; 2} - 4 - 2.2 Term. The term of this Lease shall be for a period beginning on the Commencement Date and expiring on May 31, 2025. 2.3 Measurement of the Premises. Landlord and Tenant agree that the Premises Rentable Area identified in Section 1.1 is recited for Landlord’s administrative purposes only and that the actual measurement of the Premises may be more or less than the number identified, irrespective of measurement method used. ARTICLE 3 Commencement and Condition 3.1 Commencement Date. The Commencement Date shall be as specified in Section 1.1 above. 3.2 Condition of the Premises. Tenant agrees to accept the Premises in “as is” condition on the Commencement Date and acknowledges that Landlord has completed all improvements it has required Landlord to perform and that Landlord shall have no obligation to make any alterations or improvements to the Premises or to provide Tenant with any funds for such purpose. ARTICLE 4 Rent, Additional Rent, Insurance and Other Charges 4.1 The Annual Fixed Rent. Tenant shall pay Annual Fixed Rent to Landlord, or as otherwise directed by Landlord, without offset, abatement (except as provided in Article 7), deduction or demand. Annual Fixed Rent shall be payable in equal monthly installments, in advance, on the first day of each and every calendar month during the term of this Lease, at the Address for Payment of Rent, or at such other place as Landlord shall from time to time designate by notice, by check drawn on a domestic bank. 4.2 Additional Rent. Tenant shall pay to Landlord, as Additional Rent, Tenant’s Percentage of Taxes and Operating Costs as provided in Sections 4.2.1 and 4.2.2, and all other charges and amounts payable by or due from Tenant to Landlord (all such amounts referred to in this sentence being “Additional Rent”). 4.2.1 Real Estate Taxes. If Taxes (as hereinafter defined) assessed against the Property (or estimated to be due by governmental authority) for any fiscal tax period (a “Tax Year”) during the term of this Lease shall exceed Base Taxes, whether due to increase in rate or reassessment of the Property, or both, Tenant shall reimburse Landlord, as Additional Rent, for Tenant’s Percentage of any such excess (such amount being hereinafter referred to as the “Tax Excess”). Tenant shall pay to Landlord, as Additional Rent on the first day of each calendar month during the term but otherwise in the manner provided for the payment of Annual Fixed Rent, estimated payments on account of the Tax Excess, such monthly amounts to be sufficient to provide Landlord by the time Tax payments are due or are to be made by Landlord a sum equal to the Tax Excess for the then current Tax Year, as reasonably estimated by Landlord from time to time. Within a reasonable period of time after the end of each Tax Year during the term,

{B1878467; 2} - 5 - Landlord shall give Tenant a notice setting forth the amount of Taxes for the preceding Tax Year and a computation of any Tax Excess. If the total of Tenant’s monthly remittances on account of the Tax Excess for any Tax Year is greater than the Tax Excess for such Tax Year, Landlord shall credit such overpayment against Tenant’s subsequent obligations on account of Taxes (or promptly refund such overpayment if the term of this Lease has ended and Tenant has no further obligations to Landlord); if the total of such remittances is less than the Tax Excess for such Tax Year, Tenant shall pay the difference to Landlord within ten (10) days after being so notified by Landlord. If the Commencement Date shall occur or the term of this Lease shall expire or be terminated during any Tax Year, or the Tax Year or if the period of assessment of real estate taxes is changed or be more or less than one (1) year, or if Tenant’s Percentage is modified during any Tax Year due to a change in the rentable area of the Building and/or the Premises or otherwise, then the amount of Tax Excess which may be otherwise payable by Tenant as provided in this subsection 4.2.1 shall be pro-rated on a daily basis based. “Taxes” shall mean all taxes, assessments, excises and other charges and impositions which are general or special, ordinary or extraordinary, foreseen or unforeseen, of any kind or nature which are levied, assessed or imposed by any governmental authority upon or against or with respect to the Property, Landlord or the owner or lessee of personal property used by or on behalf of Landlord in connection with the Property, or taxes in lieu thereof, and additional types of taxes to supplement real estate taxes due to legal limits imposed thereon. If, at any time, any tax or excise on rents or other taxes, however described, are levied or assessed against Landlord, either wholly or partially in substitution for, or in addition to, real estate taxes assessed or levied on the Property, such tax or excise on rents or other taxes shall be included in Taxes; however, Taxes shall not include franchise, estate, inheritance, succession, capital levy, income (except to the extent that a tax on income or revenue is levied solely on rental revenues and not on other types of income and then only from rental revenue generated by the Property) or excess profits taxes assessed on Landlord. Taxes also shall include all court costs, attorneys’, consultants’ and accountants’ fees, and other expenses incurred by Landlord in analyzing and contesting Taxes through and including all appeals. Taxes shall include any estimated payment made by Landlord on account of a fiscal tax period for which the actual and final amount of taxes for such period has not been determined by the governmental authority as of the date of any such estimated payment. 4.2.2 Operating Costs. If, during the term hereof, Operating Costs (as hereinafter defined) paid or incurred by Landlord in any twelve-month period established by Landlord (an “Operating Year”) shall exceed Base Operating Costs, Tenant shall reimburse Landlord, as Additional Rent, for Tenant’s Percentage of any such excess (such amount being hereinafter referred to as the “Operating Cost Excess”). Tenant shall pay to Landlord, as Additional Rent, on the first day of each calendar month during the term but otherwise in the manner provided for the payment of Annual Fixed Rent, estimated payments on account of the Operating Cost Excess, such monthly amounts to be sufficient to provide to Landlord, by the end of each Operating Year, a sum equal to the Operating Cost Excess for such Operating Year, as estimated by Landlord from time to time. Within a reasonable period of time after the end of each Operating Year during the term, Landlord shall furnish to Tenant an itemized statement setting forth the amount of Operating Costs for the preceding Operating Year and a computation of any Operating Cost Excess, prepared and computed in accordance with Landlord’s prevailing

{B1878467; 2} - 6 - customs and practices, consistently applied. Any such year-end statement by Landlord relating to Operating Costs shall be final and binding upon Tenant unless it shall within thirty (30) days after receipt thereof, contest any items therein by giving notice to Landlord specifying each item contested and the reasons therefor. If, at the expiration of each Operating Year in respect of which monthly installments on account of the Operating Cost Excess shall have been made as aforesaid, the total of such monthly remittances is greater than the Operating Cost Excess for such Operating Year, Landlord shall credit such overpayment against Tenant’s subsequent obligations on account of Operating Costs (or promptly refund such overpayment if the term of this Lease has ended and Tenant has no further obligation to Landlord); if the total of such remittances is less than the Operating Cost Excess for such Operating Year, Tenant shall pay the difference to Landlord within ten (10) days after being so notified by Landlord. In no event shall Tenant be entitled to receive any reimbursement or credit if Operating Costs for any Operating Year are less than Base Operating Costs. If the Commencement Date shall occur or the term of this Lease shall expire or be terminated during any Operating Year or Tenant’s Percentage be modified during any Operating Year due to a change in the rentable area of the Building and/or the Premises or otherwise, the amount of the Operating Cost Excess which may be payable by Tenant as provided in this subsection 4.2.2 shall be pro-rated on a daily basis. “Operating Costs” shall be all costs and expenses paid or incurred for the operation, cleaning, management, maintenance, insurance, repair, replacement, decoration, upkeep, protection and security of the Property or any part or component thereof. If any item of Operating Costs is a capital expenditure, Landlord may include in Operating Costs for such Operating Year in which such expenditure was made and in Operating Costs for each succeeding Operating Year an annual charge-off of such capital expenditure. Annual charge-offs shall be determined by dividing the original capital expenditure plus an interest factor, reasonably determined by Landlord as being the interest rate then being charged for long-term mortgages by institutional lenders on like properties within the locality in which the Building is located, by the number of years of useful life of the improvement, repair, alteration or replacement made with the capital expenditure; as determined reasonably by Landlord. In addition, if during any portion of any Operating Year for which Operating Costs are being computed, less than ninety five percent (95%) of the rentable area of the Building was leased to tenants or if Landlord is supplying less than ninety five percent (95%) of the rentable area of the Building with the services and utilities being supplied hereunder, actual Operating Costs incurred shall be reasonably projected by Landlord on an item-by-item basis to the estimated Operating Costs that would have been incurred if ninety five percent (95%) of the Building were occupied for such Operating Year and such services and utilities were being supplied to ninety five percent (95%) of the rentable area of the Building, and such projected amount shall, for the purposes hereof, be deemed to be the Operating Costs for such Operating Year. 4.3 Personal Property Taxes. Tenant shall pay all taxes charged, assessed or imposed upon the personal property of Tenant in or upon the Premises.

{B1878467; 2} - 7 - 4.4 Insurance. 4.4.1 Insurance Policies. Tenant shall, at its expense, take out and maintain, throughout the term of this Lease, the following insurance: 4.4.1.1 Commercial general liability insurance (on an occurrence basis, including without limitation, broad form contractual liability, bodily injury, property damage, fire legal liability, and products and completed operations coverage) under which Tenant is named as an insured and Landlord and Landlord’s Agent (and the holder of any mortgage on the Premises or Property, as set out in a notice from time to time) are named as additional insureds as their interests may appear, in an amount which shall, at the beginning of the term, be at least equal to the Commercial General Liability Insurance Limits, and, which, from time to time during the term, shall be for such higher limits, if any, as Landlord shall determine to be customarily carried in the area in which the Property is located for premises similar to the Premises which are used for similar purposes and which are located in properties comparable to the Building; 4.4.1.2 Worker’s compensation insurance with statutory limits covering all of Tenant’s employees working on the Premises; 4.4.1.3 So-called “special form” property insurance on a “replacement cost” basis with an agreed value endorsement covering all furniture, furnishings, fixtures and equipment and other personal property brought to the Premises by Tenant and anyone acting under Tenant and all improvements and betterments to the Premises performed at Tenant’s expense; 4.4.1.4 So-called “business income and extra expense” insurance covering twelve months loss of income; and 4.4.1.5 Such other insurance, in such amounts, as Landlord shall determine are customarily carried in the area in which the Property is located for premises similar to the Premises which are used for similar purposes and which are located in properties comparable to the Building. 4.4.2 Requirements. All such policies shall contain deductibles not in excess of that reasonably approved by Landlord, shall contain a clause confirming that such policy and the coverage evidenced thereby shall be primary with respect to any insurance policies carried by Landlord and shall be obtained from responsible companies qualified to do business and in good standing in the state or district in which the Property is located, which companies shall have a general policy holder’s rating by A.M. Best of at least A+ X or otherwise be acceptable to Landlord. A certificate of the insurer, certifying that such policy has been issued and paid in full, providing the coverage required by this Section and containing provisions specified herein, shall be delivered to Landlord prior to the commencement of the term of this Lease and, upon renewals, not less than thirty (30) days prior to the expiration of such coverage. Each such policy shall be non-cancelable and not materially changed with respect to the interest of Landlord and such mortgagees of the Property (and others that are in privity of estate with Landlord of which Landlord provides notice to Tenant from time to time) without at least thirty (30) days’ prior written notice thereto. Any insurance required of Tenant under this Lease may

{B1878467; 2} - 8 - be furnished by Tenant under a blanket policy carried by it provided that such blanket policy shall reference the Premises, and shall guarantee a minimum limit available for the Premises equal to the insurance amounts required in this Lease. 4.4.3 Waiver of Subrogation. Landlord and Tenant shall each endeavor to secure an appropriate clause in, or an endorsement upon, each property damage insurance policy obtained by it and covering the Building, the Premises or the personal property, fixtures and equipment located therein or thereon, pursuant to which the respective insurance companies waive subrogation and permit the insured, prior to any loss, to agree with a third party to waive any claim it might have against said third party. The waiver of subrogation or permission for waiver of any claim hereinbefore referred to shall extend to the agents of each party and its employees and, in the case of Tenant, shall also extend to all other persons and entities occupying or using the Premises by, through or under Tenant. If and to the extent that such waiver or permission can be obtained only upon payment of an additional charge then the party benefiting from the waiver or permission shall pay such charge upon demand, or shall be deemed to have agreed that the party obtaining the insurance coverage in question shall be free of any further obligations under the provisions hereof relating to such waiver or permission from such insurance companies. Subject to the foregoing provisions of this Subsection 4.4.3, and insofar as may be permitted by the terms of the property insurance policies carried by it, each party hereby releases the other with respect to any claim which it might otherwise have against the other party for any loss or damage to its property to the extent such damage is actually covered or would have been covered by policies of property insurance required by this Lease to be carried by the respective parties hereunder. In addition, Tenant agrees to exhaust any and all claims against its insurer(s) prior to commencing an action against Landlord for any loss covered by insurance required to be carried by Tenant hereunder. 4.5 Utilities. Tenant shall during the term pay all electricity charges allocable to the Premises and all charges for telephone and other utilities or services not supplied by Landlord pursuant to Subsections 5.1.1 and 5.1.2, whether designated as a charge, tax, assessment, fee or otherwise, all such charges to be paid as the same from time to time become due. Except as otherwise provided in this Subsection 4.5 or in Article 5, it is understood and agreed that Tenant shall make its own arrangements for the installation or provision of all utilities and services and that Landlord shall be under no obligation to furnish any utilities to the Premises. Tenant acknowledges that Annual Fixed Rent does not include the cost of supplying electricity to the Premises. Electricity supplied to a portion of the Premises located on the second floor is submetered and the electricity supplied to the remainder of the Premises is separately metered. Tenant shall pay to Landlord, as Additional Rent, the cost to Landlord of the submetered electricity supplied to the Premises, as reasonably determined by Landlord on the basis of such submetering and the cost of maintaining and repairing the submeter. Tenant shall contract directly with the public utility for all other electricity supplied to the Premises and shall pay all bills therefor when due. Tenant shall also be responsible, at its expense, for any necessary maintenance, repair or replacement of the separate electric meter(s) serving the Premises. 4.6 Late Payment of Rent. If any installment of Annual Fixed Rent or any Additional Rent is not paid on or before the date the same is due, it shall bear interest (as Additional Rent)

{B1878467; 2} - 9 - from the date due until the date paid at the Default Rate (as defined in Section 8.4). Absent specific provision to the contrary, all Additional Rent shall be due and payable in full thirty (30) days after written demand by Landlord. ARTICLE 5 Landlord’s Covenants 5.1 Affirmative Covenants. Landlord shall provide the following: 5.1.1 Heat and Air-Conditioning. Landlord shall provide and maintain heat, ventilation and air-conditioning (“HVAC”) equipment sufficient to maintain the Premises at comfortable temperatures for general office use, subject to all federal, state and municipal regulations, during Normal Building Operating Hours (as defined in the Rules and Regulations) and subject to compliance by Tenant with the following and the provisions of Section 6.2.4. If Tenant shall require HVAC at times other than Normal Building Operating Hours, Landlord may furnish such service and Tenant shall pay therefor such charges as may from time to time be in effect. If the temperature otherwise maintained in any portion of the Premises by the HVAC system is affected as a result of (i) the type or quantity of any lights, machines or equipment used by Tenant in the Premises, (ii) the occupancy of any portion of the Premises by more than one person per two hundred (200) square feet of rentable area, (iii) an electrical load for lighting or power in excess of the limits specified in Section 6.2.4, or (iv) any partitioning or other improvements installed by Tenant, then at Tenant’s sole cost, Landlord may install any equipment, or modify any existing equipment Landlord deems necessary to restore the temperature balance. Tenant agrees to keep closed, when necessary, blinds or other window treatments which, because of the sun’s position, must be closed to provide for the efficient operation of the air conditioning system, and Tenant agrees to cooperate with Landlord and to abide by the reasonable regulations and requirements which Landlord may prescribe for the proper functioning and protection of the HVAC system. Landlord shall have no responsibility for providing any service from Separate HVAC Equipment, as defined in Section 6.1.3. 5.1.2 Cleaning; Water. Landlord shall provide cleaning, maintenance and landscaping to the common areas of the Building and Property (including snow removal to the extent necessary to maintain reasonable access to the Building) in accordance with standards generally prevailing throughout the term hereof in comparable office buildings in the Newton, Massachusetts area; and furnish water for ordinary drinking, lavatory and toilet facilities (as opposed to special laboratory or other uses in excess of general office uses) and shall cause the Premises to be cleaned in accordance with the standards set forth in Exhibit G. Tenant shall pay to Landlord upon invoice the actual costs incurred by Landlord for (x) extra cleaning work in the Premises required because of carelessness, indifference, misuse or neglect on the part of Tenant or its subtenants or its or their employees or visitors, and (y) removal from the Premises and the Building of any refuse and rubbish of Tenant in excess of that ordinarily accumulated in business office occupancy, including, without limitation, kitchen refuse, or at times other than Landlord’s standard cleaning times. Notwithstanding the foregoing, Landlord shall not be required to clean any portions of the Premises used for preparation, serving or consumption of food or beverages or other special purposes if same require greater or more difficult cleaning work than office areas, and Tenant agrees, at Tenant’s expense, to retain Landlord’s cleaning contractor to

{B1878467; 2} - 10 - perform such extra cleaning, provided that the charges of such cleaning contractor shall be commercially reasonable. Landlord, its cleaning contractor and their respective employees shall have access to the Premises after 6:00 p.m. and before 8:00 a.m. and shall have the right to use, without charge therefor, all light, power and water in the Premises reasonably required to clean the Premises as required hereunder. If Tenant uses water for any purpose other than ordinary drinking, lavatory and toilet purposes, Landlord may assess a reasonable charge for the additional water so used, or install a water meter and thereby measure Tenant’s water consumption for all purposes. In the latter event, Tenant shall pay the cost of the meter and the cost of installation thereof and shall keep such meter and installation equipment in good working order and repair. Tenant agrees to pay for water consumed, as shown on such meter, together with the sewer charge based on such meter charges, as and when bills are rendered, and if Tenant shall fail to make such payment, Landlord may pay such charges and collect the same from Tenant as Additional Rent. 5.1.3 Elevator, Lighting and Electricity. Landlord shall furnish non-exclusive passenger elevator service from the lobby to the Premises; purchase and install, at Tenant’s expense, all building standard lamps, tubes, bulbs, starters and ballasts for lighting fixtures in the Premises; provide lighting to public and common areas of the Property; and arrange for the supply of electrical power to the Premises to accommodate a load not exceeding the limitations contained in Section 6.2.4. 5.1.4 Repairs. Except as otherwise expressly provided herein, Landlord shall make such repairs and replacements to the roof, exterior walls, floor slabs and other structural components of the Building, and to the common areas and facilities of the Building (including any common plumbing, electrical and HVAC equipment, elevators and any other common equipment or systems in the Building) as may be necessary to keep them in good repair and condition (exclusive of equipment installed by Tenant and except for those repairs required to be made by Tenant pursuant to Subsection 6.1.3 hereof and repairs or replacements occasioned by any act or negligence of Tenant, its servants, agents, customers, contractors, employees, invitees, or licensees). 5.2 Interruption. Landlord shall have no responsibility or liability to Tenant for failure, interruption, inadequacy, defect or unavailability of any services, facilities, utilities, repairs or replacements or for any failure or inability to provide access or to perform any other obligation under this Lease caused by breakage, accident, fire, flood or other casualty, strikes or other labor trouble, order or regulation of or by any governmental authority, inclement weather, repairs, inability to obtain or shortages of utilities, supplies, labor or materials, war, civil commotion or other emergency, transportation difficulties or due to any act or neglect of Tenant or Tenant’s servants, agents, employees or licensees or for any other cause beyond the reasonable control of Landlord, and in no event shall Landlord be liable to Tenant for any indirect or consequential damages suffered by Tenant due to any such failure, interruption, inadequacy, defect or unavailability; and failure or omission on the part of Landlord to furnish any of same for any of the reasons set forth in this paragraph shall not be construed as an eviction of Tenant, actual or constructive, nor entitle Tenant to an abatement of rent, nor render

{B1878467; 2} - 11 - the Landlord liable in damages, nor release Tenant from prompt fulfillment of any of its covenants under this Lease. Landlord reserves the right to deny access to the Building and to interrupt the services of the HVAC, plumbing, electrical or other mechanical systems or facilities in the Building when necessary from time to time by reason of accident or emergency, or for repairs, alterations, replacements or improvements which in the reasonable judgment of Landlord are desirable or necessary, until such repairs, alterations, replacements or improvements shall have been completed. Landlord shall use reasonable efforts to minimize the duration of any such interruption and to give to Tenant at least three (3) days’ notice if service is to be interrupted, except in cases of emergency. 5.3 Outside Services.

Notwithstanding the foregoing, Landlord further reserves the right to close the Parking Facility or portions thereof temporarily to the extent necessary for maintenance and repairs. Tenant acknowledges that Landlord is not required to provide any security or security services for any of the Parking Facility. Tenant hereby indemnifies and agrees to defend and hold Landlord harmless from and against all claims, loss, cost, or damage arising out of the use by Tenant and its employees and invitees of the Parking Facility, except to the extent caused by gross negligence or willful misconduct of Landlord or Landlord’s agent or employees.

{B1878467; 2} - 17 - and expenses, consultant fees, and expert fees that arise from or are caused in whole or in part, directly or indirectly, by (i) the presence or suspected presence in, on, under or about the Premises or discharge in or from the Premises of any Hazardous Materials, or Tenant’s use, analysis, storage, transportation, disposal, release, threatened release, discharge or generation of Hazardous Materials to, in, on, under, about or from the Premises, or (ii) Tenant’s failure to comply with any Environmental Laws. Tenant’s obligations hereunder shall include, without limitation, and whether foreseeable or unforeseeable, all costs (including, without limitation, capital, operating and maintenance costs) incurred in connection with any investigation or monitoring of site conditions, repair, cleanup, containment, remedial, removal or restoration work, or detoxification or decontamination of the Premises, and the preparation and implementation of any closure, remedial action or other required plans in connection therewith. For purposes of this Section 6.2.7, any acts or omissions of Tenant, or its subtenants or assignees or its or their employees, agents, or contractors (whether or not they are negligent, intentional, willful or unlawful) shall be attributable to Tenant. The term “Hazardous Materials” shall mean and include any oils, petroleum products, asbestos, radioactive, biological, medical or infectious wastes or materials, and any other toxic or hazardous wastes, materials and substances which are defined, determined or identified as such in any Environmental Laws, or in any judicial or administrative interpretation of Environmental Laws. The term “Environmental Laws” shall mean any and all federal, state and municipal statutes, laws, regulations, ordinances, rules, judgments, orders, decrees, codes, plans, injunctions, permits, concessions, grants, franchises, licenses, agreements or other governmental restrictions relating to the environment or to emissions, discharges or releases of pollutants, contaminants, petroleum or petroleum products, medical, biological, infectious, toxic or hazardous substances or wastes into the environment including, without limitation, ambient air, surface water, ground water or land, or otherwise relating to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of pollutants, contaminants, petroleum or petroleum products, medical, biological, infectious, toxic or hazardous substances or wastes or the cleanup or other remediation thereof. ARTICLE 7 Casualty or Taking 7.1 Termination. In the event that the Premises or the Property, or any material part thereof shall be destroyed or damaged by fire or casualty, shall be taken by any public authority or for any public use or shall be condemned by the action of any public authority, then the term of this Lease may be terminated at the election of Landlord. Such election, which may be made notwithstanding the fact that Landlord’s entire interest may have been divested, shall be made by the giving of notice by Landlord to Tenant within one hundred twenty (120) days after the date of the taking or casualty. 7.2 Restoration. If Landlord does not elect to so terminate, this Lease shall continue in force and (so long as the damage is not caused by the negligence or other wrongful act of Tenant or its employees, agents, contractors or invitees) a just proportion of the Annual Fixed Rent reserved, according to the nature and extent of the damages sustained by the Premises, shall

{B1878467; 2} - 18 - be suspended or abated until the Premises (excluding any improvements to the Premises made at Tenant’s expense), or what may remain thereof, shall be put by Landlord in proper condition for use, which Landlord covenants to do with reasonable diligence to the extent permitted by the net proceeds of insurance recovered or damages awarded for such destruction, taking, or condemnation and subject to zoning and building laws or ordinances then in existence. “Net proceeds of insurance recovered or damages awarded” refers to the gross amount of such insurance or damages actually made available to Landlord (and not retained by any Superior Lessor or Superior Mortgagee) less the reasonable expenses of Landlord incurred in connection with the collection of the same, including without limitation, fees and expenses for legal and appraisal services. 7.3 Award. Irrespective of the form in which recovery may be had by law, all rights to seek reimbursement for damages or compensation arising from fire or other casualty or any taking by eminent domain or condemnation shall belong to Landlord in all cases. Tenant hereby grants to Landlord all of Tenant’s rights to such claims for damages and compensation and covenants to deliver such further assignments thereof as Landlord may from time to time request. Nothing contained herein shall be construed to prevent Tenant from prosecuting in any condemnation proceedings a claim for relocation expenses, provided that such action shall not affect the amount of compensation otherwise recoverable by Landlord from the taking authority. 7.4 Effect of Casualty or Taking on the Tax Excess and the Operating Cost Excess. In the event of any taking, condemnation or damage by fire or casualty affecting the Property whereby the term of this Lease shall not terminate pursuant to the provisions of Section 7.1, then for purposes of determining the Operating Cost Excess or Tax Excess there shall be established new Base Taxes and Base Operating Costs as hereinafter provided. Base Taxes shall be a product of the initial Base Taxes as recited in Section 1.1 multiplied by a fraction, the numerator of which shall be the Taxes for the first full Tax Year subsequent to the taking, condemnation or damage which reflects the occurrence of such taking, condemnation or damage (the “Revised Tax Year”), and the denominator of which shall be the Taxes for the full Tax Year prior to such taking, condemnation or damage; and Base Operating Costs shall be the product of the initial Base Operating Costs as recited in Section 1.1 multiplied by a fraction, the numerator of which shall be Operating Costs for the first full Operating Year subsequent to such taking, condemnation or damage which reflects the occurrence of such taking, condemnation or damage (the “Revised Operating Year”) and the denominator of which shall be the Operating Costs for the full Operating Year prior to such taking, condemnation or damage. The foregoing revisions shall be effective as of the first day of the Revised Tax Year or the Revised Operating Year (as applicable). Effective as of the date of any such taking, condemnation or damage, Tenant’s Percentage shall be adjusted appropriately to reflect the change, if any, in the rentable area of the Premises and/or the rentable area of the Building.

{B1878467; 2} - 19 - default, or (II) if as promptly as possible but in any event within thirty (30) days after notice from Landlord to Tenant specifying any default or defaults other than those set forth in clause (I) Tenant has not cured the default or defaults so specified; or (b) if any assignment shall be made by Tenant for the benefit of creditors; or (c) if Tenant’s leasehold interest shall be taken on execution; or (d) if a lien or other involuntary encumbrance shall be filed against Tenant’s leasehold interest or Tenant’s other property, including said leasehold interest, and shall not be discharged within ten (10) days thereafter; or (e) if a petition shall be filed by Tenant for liquidation, or for reorganization or an arrangement under any provision of any bankruptcy law or code as then in force and effect; or (f) if an involuntary petition under any of the provisions of any bankruptcy law or code shall be filed against Tenant and such involuntary petition shall not be dismissed within thirty (30) days thereafter; or (g) if a custodian or similar agent shall be authorized or appointed to take charge of all or substantially all of the assets of Tenant or (h) if Tenant dissolves or shall be dissolved or shall liquidate or shall adopt any plan or commence any proceeding, the result of which is intended to include dissolution or liquidation; or (i) if any order shall be entered in any proceeding by or against Tenant decreeing or permitting the dissolution of Tenant or the winding up of its affairs; or (j) if Tenant shall fail to pay any installment of Annual Fixed Rent or Additional Rent when due, Tenant shall cure such default within the grace period provided in clause (a) (I) above (or with Landlord’s approval after the expiration of such grace period) and Tenant shall, within the next year following the date such initial defaulted payment was first due, fail more than once to pay any installment of Annual Fixed Rent or Additional Rent when due, then, and in any of such cases indicated in clauses (a) through (j) hereof (collectively and individually, a “Default of Tenant”), Landlord may, in addition to and not in derogation of any remedies for any preceding breach of covenant, immediately or at any time thereafter (x) give notice to Tenant terminating this Lease and/or the term hereof, which notice shall specify the date of such termination, whereupon on the date so specified, the term of this Lease and all of Tenant’s rights and privileges under this Lease shall expire and terminate or (y) without terminating this Lease terminate Tenant's right of possession and/or occupancy and reenter and take possession of the Premises or any part thereof, without notice and expel Tenant and any party claiming under Tenant and remove any of their effects, without being liable on account thereof, whether in trespass or breach or covenant or otherwise, (and no such reentry or taking possession shall be construed as an election by Landlord to terminate this Lease unless Landlord shall affirm such election by notice expressly to such effect), but in either case Tenant shall remain liable as hereinafter provided. 8.2 Remedies. In the event of any termination of this Lease or the term hereof pursuant to Section 8.1, Tenant shall pay the Annual Fixed Rent, Additional Rent and other charges payable hereunder up to the time of such termination. Thereafter, whether or not the Premises shall have been re let, Tenant shall be liable to Landlord for, and shall pay to Landlord the Annual Fixed Rent, Additional Rent and other charges which would be payable hereunder for the remainder of the term of this Lease had such termination not occurred, less the net proceeds, if any, of any reletting of the Premises, after deducting all expenses in connection with such reletting, including, without limitation, all repossession costs, brokerage commissions, attorneys’ fees and expenses, advertising costs, administration expenses, alteration costs, the value of any tenant inducements (including but without limitation free rent, moving costs, and contributions toward leasehold improvements) and any other expenses incurred in preparation for such reletting. Tenant shall pay such damages to Landlord monthly on the days on which the Annual Fixed Rent, Additional Rent or other charges would have been payable hereunder if the term of this Lease had not been so terminated.

{B1878467; 2} - 20 - In the event of any reentry or retaking of possession of the Premises and/or termination of Tenant's right of possession and/or occupancy of the Premises, as applicable, without termination of this Lease, pursuant to Section 8.1, Tenant shall pay the Annual Fixed Rent, Additional Rent and other charges payable hereunder up to the time of such reentry or retaking of possession and/or termination. Thereafter, whether or not the Premises shall have been re-let, Tenant shall be liable to Landlord for, and shall pay to Landlord the Annual Fixed Rent, Additional Rent and other charges which would be payable hereunder for the remainder of the term of this Lease notwithstanding any such reentry, retaking of possession or termination, less the net proceeds, if any, of any reletting of the Premises, after deducting all expenses in connection with such reletting, including, without limitation, all repossession costs, brokerage commissions, attorneys’ fees and expenses, advertising costs, administration expenses, alteration costs, the value of any tenant inducements (including but without limitation free rent, moving costs, and contributions toward leasehold improvements) and any other expenses incurred in preparation for such reletting. Tenant shall pay such damages to Landlord monthly on the days on which the Annual Fixed Rent, Additional Rent or other charges are payable hereunder. At any time after any such termination, reentry or retaking of possession, in lieu of recovering damages pursuant to the provisions of the immediately preceding paragraphs with respect to any period after the date of demand therefor, at Landlord’s election, Tenant shall pay to Landlord immediately and in full the greater of (i) the amount, if any, by which (A) the Annual Fixed Rent, Additional Rent and other charges which would be payable hereunder from the date of such demand to the end of what would be the then unexpired term of this Lease had such termination not occurred (or in the case of reentry or retaking of possession of the Premises by Landlord or a termination of Tenant’s right of possession and/or occupancy of the Premises, to the end of the term of this Lease), shall exceed (B) the then fair rental value of the Premises for the same period, reduced to amortize over such period all costs or expenses which Landlord would incur to obtain such fair market rent, or (ii) an amount equal to the lesser of (x) the Annual Fixed Rent, Additional Rent and other charges that would have been payable for the remainder of the term of this Lease had such termination not occurred (or in the case of reentry or retaking of possession of the Premises by Landlord or a termination of Tenant’s right of possession and/or occupancy of the Premises, to the end of the term of this Lease) or (y) the aggregate of the Annual Fixed Rent, Additional Rent and other charges accrued in the twelve (12) months ended next prior to such termination, reentry or retaking of possession of the Premises by Landlord or termination of Tenant's right of possession and/or occupancy (without reduction for any free rent or other concession or abatement) except that in the event the term of this Lease or Tenant’s right of possession and/or occupancy of the Premises is so terminated or Landlord shall reenter and/or retake possession of the Premises prior to the expiration of the first full year of the term of this Lease, the damages which Landlord may elect to recover pursuant to clause (ii) (y) of this paragraph shall be calculated as if any such termination, reentry or retaking of possession had occurred on the first anniversary of the Commencement Date. Nothing contained in this Lease shall, however, limit or prejudice the right of Landlord to prove for and obtain in proceedings for bankruptcy or insolvency by reason of the termination of this Lease, an amount equal to the maximum allowed by any statute or rule of law in effect at the time when, and governing the proceedings in which, the damages are to be proved, whether or not the amount be greater than, equal to, or less than the amount of the loss or damages referred to above.

{B1878467; 2} - 21 - In case of any Default of Tenant, re-entry, expiration and repossession by summary proceedings or otherwise, Landlord may (i) relet the Premises or any part or parts thereof, either in the name of Landlord, Tenant (Tenant hereby irrevocably appointing Landlord its attorney in fact to execute any instrument of reletting on behalf of Tenant) or otherwise (as Landlord may elect), for a term or terms which may at Landlord’s option be equal to or less than or exceed the period the balance of the term of this Lease (or the balance of the term of this Lease if it shall not have been terminated) and may grant concessions or free rent to the extent that Landlord considers advisable and necessary to relet the same and (ii) may make such alterations, repairs and decorations in the Premises as Landlord in its sole judgment considers advisable and necessary for the purpose of reletting the Premises; and the making of such alterations, repairs and decorations shall not operate or be construed to release Tenant from liability hereunder as aforesaid. Landlord shall in no event be required to relet the Premises or otherwise mitigate damages or be liable in any way whatsoever for failure to relet the Premises, or, in the event that the Premises are relet, for failure to collect the rent under such reletting. To the fullest extent permitted by law, Tenant hereby expressly waives any and all rights of redemption granted under any present or future laws in the event of Tenant being evicted or dispossessed, or in the event of Landlord obtaining possession of the Premises, by reason of the violation by Tenant of any of the covenants and conditions of this Lease. 8.3 Remedies Cumulative. Except as expressly provided otherwise in Section 8.2, any and all rights and remedies which Landlord may have under this Lease, and at law and equity (including without limitation actions at law for direct, indirect, special and consequential (foreseeable and unforeseeable) damages), for Tenant’s failure to comply with its obligations under this Lease shall be cumulative and shall not be deemed inconsistent with each other, and any two or more of all such rights and remedies may be exercised at the same time insofar as permitted by law. 8.4 Landlord’s Right to Cure Defaults. At any time with or without notice, Landlord shall have the right, but shall not be required, to pay such sums or do any act which requires the expenditure of monies which may be necessary or appropriate by reason of the failure or neglect of Tenant to comply with any of its obligations under this Lease (irrespective of whether the same shall have ripened into a Default of Tenant), and in the event of the exercise of such right by Landlord, Tenant agrees to pay to Landlord forthwith upon demand, as Additional Rent, all such sums including reasonable attorneys fees, together with interest thereon at a rate (the “Default Rate”) equal to ten percent (10%) per annum. 8.5 Holding Over. Any holding over by Tenant of all or any portion of the Premises after the expiration or early termination of the term of this Lease shall be treated as a daily tenancy at sufferance at a rental rate equal to 150% of the sum of Annual Fixed Rent plus Additional Rent on account of Operating Costs and Taxes in effect immediately prior to the expiration or earlier termination of the term (prorated on a daily basis). Tenant shall also pay to Landlord all damages, direct and/or consequential (foreseeable and unforeseeable), sustained by reason of any such holding over. Otherwise, all of the covenants, agreements and obligations of Tenant applicable during the term of this Lease shall apply and be performed by Tenant during such period of holding over as if such period were part of the term of this Lease.

{B1878467; 2} - 22 - 8.6 Effect of Waivers of Default. Any consent or permission by Landlord to any act or omission by Tenant shall not be deemed to be consent or permission by Landlord to any other similar or dissimilar act or omission and any such consent or permission in one instance shall not be deemed to be consent or permission in any other instance. 8.7 No Waiver, etc. The failure of Landlord or Tenant to seek redress for violation of, or to insist upon the strict performance of, any covenant or condition of this Lease shall not be deemed a waiver of such violation nor prevent a subsequent act, which would have originally constituted a violation, from having all the force and effect of an original violation. The receipt by Landlord of rent with knowledge of the breach of any covenant of this Lease shall not be deemed to have been a waiver of such breach by Landlord, or by Tenant, unless such waiver be in writing signed by the party to be charged. No consent or waiver, express or implied, by Landlord or Tenant to or of any breach of any agreement or duty shall be construed as a waiver or consent to or of any other breach of the same or any other agreement or duty. 8.8 No Accord and Satisfaction. No acceptance by Landlord of a lesser sum than the Annual Fixed Rent, Additional Rent or any other charge then due shall be deemed to be other than on account of the earliest installment of such rent or charge due, nor shall any endorsement or statement on any check or any letter accompanying any check or payment as rent or other charge be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance of such installment or pursue any other remedy in this Lease provided. ARTICLE 9 Rights of Holders This Lease, and all rights of Tenant hereunder, are and shall be subject and subordinate to any ground or master lease, and all renewals, extensions, modifications and replacements thereof, and to all mortgages, which may now or hereafter affect the Building or the Property and/or any such lease, whether or not such mortgages shall also cover other lands and/or buildings and/or leases, to each and every advance made or hereafter to be made under such mortgages, and to all renewals, modifications, replacements and extensions of such leases and such mortgages and all consolidations of such mortgages.

In confirmation of such subordination, Tenant shall promptly execute, acknowledge and deliver any instrument that Landlord, the lessor under any such lease or the holder of any such mortgage or any of their respective successors in interest may reasonably request to evidence such subordination. Any lease to which this Lease is subject and subordinate is herein called “Superior Lease” and the lessor of a Superior Lease or its successor in interest, at the time referred to, is herein called “Superior Lessor”; and any mortgage to which this Lease is subject and subordinate, is herein called “Superior Mortgage” and the holder of a Superior Mortgage is herein called “Superior Mortgagee”.

Upon such attornment, this Lease shall continue in full force and effect as a direct lease between the Successor Landlord and Tenant upon all of the terms, conditions and covenants as are set forth in this Lease, except that the Successor Landlord (unless formerly the landlord under this Lease) shall not be (a) liable in any way to Tenant for any act or omission, neglect or default on the part of Landlord under this Lease, (b) responsible for any monies owing by or on deposit with Landlord to the credit of Tenant, (c) subject to any counterclaim or setoff which theretofore accrued to Tenant against Landlord, (d) bound by any modification of this Lease subsequent to such Superior Lease or Superior Mortgage, or by any previous prepayment of Annual Fixed Rent or Additional Rent for more than one (1) month, which was not approved in writing by the Successor Landlord, (e) liable to the Tenant beyond the Successor Landlord’s interest in the Property, (f) responsible for the performance of any work to be done by Landlord under this Lease to render the Premises ready for occupancy by the Tenant, or (g) required to remove any person occupying the Premises or any part thereof, except if such person claims by, through or under the Successor Landlord. Tenant agrees at any time and from time to time to execute a suitable instrument in confirmation of Tenant’s agreement to attorn, as aforesaid. ARTICLE 10 Miscellaneous Provisions 10.1 Notices.

Landlord agrees that upon Tenant’s paying the rent and performing and observing the agreements, conditions and other provisions on its part to be performed and observed, Tenant shall and may peaceably and quietly have, hold and enjoy the Premises during the term hereof without any manner of

{B1878467; 2} - 24 - hindrance or molestation from Landlord or anyone claiming under Landlord, subject, however, to the terms of this Lease; provided, however, Landlord reserves the right at any time and from time to time, without the same constituting breach of Landlord’s covenant of quiet enjoyment or an actual or constructive eviction, and without Landlord incurring any liability to Tenant or otherwise affecting Tenant’s obligations under this Lease, to make such changes, alterations, improvements, repairs or replacements in or to the interior and exterior of the Building (including the Premises) and the fixtures and equipment thereof, and in or to the Property, or properties adjacent thereto, as Landlord may deem necessary or desirable, and to change (provided that there be no unreasonable obstruction of the right of access to the Premises by Tenant and that Landlord use commercially reasonable efforts to minimize, to the extent practical, any interference with the conduct of business at the Premises) the arrangement and/or location of entrances or passageways, doors and doorways, corridors, elevators, or other common areas of the Building and Property. Without incurring any liability to Tenant, Landlord may permit access to the Premises and open the same, whether or not Tenant shall be present, upon any demand of any receiver, trustee, assignee for the benefit of creditors, sheriff, marshal or court officer Landlord reasonably believes is entitled to such access for the purpose of taking possession of, or removing, Tenant’s property or for any other lawful purpose (but this provision and any action by Landlord hereunder shall not be deemed a recognition by Landlord that the person or official making such demand has any right or interest in or to this Lease, or in or to the Premises), or upon demand of any representative of the fire, police, building, sanitation or other department of the city, state or federal governments. 10.3 Assignment of Rents and Transfer of Title; Limitation of Landlord’s Liability. Tenant agrees that the assignment by Landlord of Landlord’s interest in this Lease, or the rents payable hereunder, whether absolute or conditional in nature or otherwise, which assignment is made to the holder of a mortgage on property which includes the Premises, shall never be treated as an assumption by such holder of any of the obligations of Landlord hereunder unless such holder shall, by notice sent to Tenant, specifically otherwise elect and that, except as aforesaid, such holder shall be treated as having assumed Landlord’s obligations hereunder (subject to the limitations set forth in Section 9.1) only upon foreclosure of such holder’s mortgage and the taking of possession of the Premises. The term “Landlord”, so far as covenants or obligations to be performed by Landlord are concerned, shall be limited to mean and include only the owner or owners at the time in question of Landlord’s interest in the Property, and in the event of any transfer or transfers of such title to said property, Landlord (and in case of any subsequent transfers or conveyances, the then grantor) shall be concurrently freed and relieved from and after the date of such transfer or conveyance, without any further instrument or agreement, of all liability with respect to the performance of any covenants or obligations on the part of Landlord contained in this Lease thereafter to be performed, it being intended hereby that the covenants and obligations contained in this Lease on the part of Landlord, shall, subject as aforesaid, be binding on Landlord, its successors and assigns, only during and in respect of their respective period of ownership of such interest in the Property. Notwithstanding the foregoing, in no event shall the acquisition of Landlord’s interest in the Property by a purchaser which, simultaneously therewith, leases Landlord’s entire interest in

{B1878467; 2} - 25 - the Property back to Landlord or the seller thereof be treated as an assumption by operation of law or otherwise, of Landlord’s obligations hereunder. Tenant shall look solely to such seller-lessee, and its successors from time to time in title, for performance of Landlord’s obligations hereunder. The seller-lessee, and its successors in title, shall be the Landlord hereunder unless and until such purchaser expressly assumes in writing the Landlord’s obligations hereunder. Tenant shall not assert nor seek to enforce any claim for breach of this Lease against any of Landlord’s assets other than Landlord’s interest in the Property, and Tenant agrees to look solely to such interest for the satisfaction of any liability or claim against Landlord under this Lease, it being specifically agreed that in no event whatsoever shall Landlord ever be personally liable for any such liability. Tenant furthermore agrees that no trustee, officer, director, general or limited partner, member, shareholder, beneficiary, employee or agent of Landlord (including any person or entity from time to time engaged to supervise and/or manage the operation of Landlord) shall be held to any liability, jointly or severally, for any debt, claim, demand, judgment, decree, liability or obligation of any kind (in tort, contract or otherwise) of, against or with respect to Landlord or arising out of any action taken or omitted for or on behalf of Landlord. 10.4 Landlord’s Default. Landlord shall not be deemed to be in breach of, or in default in the performance of, any of its obligations under this Lease unless it shall fail to perform such obligation(s) and such failure shall continue for a period of thirty (30) days, or such additional time as is reasonably required to correct any such breach or default, after written notice has been given by Tenant to Landlord specifying the nature of Landlord’s alleged breach or default. Tenant shall have no right to terminate this Lease for any breach or default by Landlord hereunder and no right, for any such breach or default, to offset or counterclaim against any rent due hereunder. In no event shall Landlord ever be liable to Tenant for any punitive damages or for any loss of business or any other indirect, special or consequential damages suffered by Tenant from whatever cause. Tenant further agrees that if Landlord shall have failed to cure any such breach or default within thirty (30) days of such notice to Landlord (or if such breach or default cannot be cured within said time, then within such additional time as may be necessary if within said thirty days Landlord has commenced and is diligently pursuing the remedies necessary to cure such breach or default), then the holder(s) of any mortgage(s) or the lessor under any ground lease entitled to notice pursuant to Section 10.5 shall have an additional thirty (30) days within which to cure such breach or default if such breach or default cannot be cured within that time, then such additional time as may be necessary, if within such thirty (30) days any such holder or lessor has commenced and is diligently pursuing the remedies necessary to cure such breach or default (including but not limited to commencement of foreclosure proceedings, if necessary to effect such cure). Where provision is made in this Lease for Landlord’s consent and Tenant shall request such consent and Landlord shall fail or refuse to give or shall delay in giving such consent, Tenant shall not be entitled to any damages and Tenant hereby waives any claim based on such failure, refusal or delay; provided however in any situation where Landlord is expressly required not to withhold its consent unreasonably Tenant shall (at its sole remedy) be entitled to bring an action for specific performance or injunction.

{B1878467; 2} - 26 - 10.5 Notice to Mortgagee and Ground Lessor. After receiving notice from any party that it holds a mortgage which includes the Premises as part of the mortgaged premises, or that it is the ground lessor under a lease with Landlord, as ground lessee, which includes the Premises as part of the demised premises, no notice from Tenant to Landlord shall be effective unless and until a copy of the same is given to such holder or ground lessor, and the curing of any of Landlord’s defaults by such holder or ground lessor shall be treated as performance by Landlord. 10.6 Brokerage. Tenant warrants and represents that it has dealt with no broker in connection with the consummation of this Lease, and in the event of any brokerage claims or liens against Landlord or the Property predicated upon or arising out of prior dealings with Tenant, Tenant agrees to defend the same and indemnify and hold Landlord harmless against any such claim, and to discharge any such lien. 10.7 Waiver of Jury Trial. LANDLORD AND TENANT HEREBY WAIVE TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY EITHER OF THEM AGAINST THE OTHER IN CONNECTION WITH THIS LEASE. 10.8 Applicable Law and Construction. This Lease shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts and if any provisions of this Lease shall to any extent be invalid, the remainder of this Lease shall not be affected thereby. Tenant expressly acknowledges and agrees that Landlord has not made and is not making, and Tenant, in executing and delivering this Lease, is not relying upon, any warranties, representations, promises or statements, except to the extent that the same are expressly set forth in this Lease or in any other written agreement which may be made between the parties concurrently with the execution and delivery of this Lease and which shall expressly refer to this Lease.

The reference contained to successors and assigns of Tenant is not intended to constitute a consent to assignment by Tenant. Except as otherwise set forth in this Lease, any obligations of Tenant (including, without limitation, rental and other monetary obligations, repair and maintenance obligations and obligations to indemnify Landlord), shall survive the expiration or earlier termination of this Lease, and Tenant shall immediately reimburse Landlord for any expense incurred by Landlord in curing Tenant’s failure to satisfy any such obligation
