              telecommunication service providers, not currently servicing the Building or Premises, which require installations or wiring within the Building or Premises. Tenant’s telecommunications vendor shall receive an electrical permit if necessary
              prior to any electrical work necessary for installation of Tenant’s telecommunications equipment. In the event that a telecommunication service provider (“Provider”) requires installation of equipment in the Building’s basement, common areas,
              or roof, Landlord may withhold its approval of Provider unless appropriate license agreements have been fully executed between Landlord and Provider. In the event that a Provider requires no equipment in the Building’s basement, common areas,
              or roof, then such approval shall not be unreasonably delayed or withheld. Tenant shall remove any wall mounted or floor mounted telecommunications equipment at the expiration of the Lease.

           

          (d) In the event that Tenant requests Landlord to coordinate tenant improvements in the Premises, other than those listed in Exhibit C, using Landlord’s vendors prior to the
              Commencement Date or at any time during the Term (“Additional Improvements “), Tenant shall pay for the Additional Improvements within fifteen (15) days of receipt of an invoice from Landlord. As compensation to Landlord for providing
              construction management services to Tenant for the Additional Improvements and for other items listed on Exhibit C completed  by  Landlord  and  paid  for by Tenant, Landlord or an affiliate of Landlord shall charge Tenant a fee of 5% of the
              total of construction and engineering costs. Upon request, Landlord will provide copies of all third-party invoices to Tenant. Failure to pay the abovementioned invoice from Landlord within fifteen (15) days shall have the same consequences
              as a failure to pay Base Rent, pursuant to Section 13.1. In the event that  either  change  orders  requested  by  Tenant  to  Landlord’s  Work,  Additional Improvements, or other improvements coordinated by Tenant delay completion of
              Landlord’s Work past the Commencement Date, then the Commencement Date shall be that date by which Landlord reasonably determines that Landlord’s Work would have been completed but for the change orders to Landlord’s Work or the Additional
              Improvements.

          (a)  Tenant agrees that the Premises shall be used and occupied by Tenant only for Permitted Uses, and only in accordance with the terms, conditions and restrictions contained
              in the Condominium Documents, and for no other purpose.

          

          

          (b)  Tenant shall be solely responsible for obtaining any and all permits, licenses or other consents required to operate its business at the Premises and shall be entirely
              responsible for all costs in connection therewith and shall operate its business in compliance with all applicable laws, rules, regulations and ordinances.

           

          
            (c)  Landlord makes no warranties or representations that the premises are fit for a particular use or purpose, including without limitation the use as specified herein, except as otherwise required by
                law.

                  ALTERATIONS BY TENANT

                


           

          (a) Tenant shall make no alterations, additions or improvements to the Premises or Condominium without Landlord’s prior written consent, not to be unreasonably withheld  or
              delayed. Any such alterations, additions or improvements shall (i) be performed in a good and workmanlike manner and in compliance with all applicable laws, rules, regulations and ordinances, specifically including City of Cambridge
              Inspectional Services requirements, (ii) be made at Tenant’s sole cost and expense, (iii) become part of the Premises and the property of Landlord, if permanently affixed to the Premises at the end of the Term.

           

          (b) All articles of personal property and all business fixtures, machinery, equipment (including telecommunications equipment affixed to the Premises) and furniture owned or
              installed in the Premises by Tenant at its expense (“Tenant’s Removable Property”) shall remain the Property of Tenant and may be removed by Tenant at any time prior to the expiration of this Lease, provided that Tenant, at its expense, shall
              repair any damage to the Building caused by such removal.

           

          (c)  Notice is hereby given that Landlord shall not be liable for any labor or materials furnished or to be furnished to Tenant upon credit, and that no mechanic’s or other lien
              for any such labor or material shall attach to or affect the interest of Landlord in and to the Premises or the Building. In the event any such lien is filed against the Property based upon any act or interest of Tenant or of anyone claiming
              through Tenant, Tenant shall immediately take such action by  bonding, deposit or payment as is necessary to remove or satisfy the lien and hereby indemnifies Landlord and holds it harmless from any and all loss, cost, damages, expense or
              liability arising there from.

                    PROHIBITION AGAINST ASSIGNMENT AND SUBLETTING

                  


          

           

          (a) Tenant shall not assign, sublet, mortgage, pledge, encumber or otherwise transfer all or any portion of its interest in the Premises, nor shall Tenant permit the Premises to
              be used or occupied by anyone other than Tenant in whole or in part without the prior written consent of Landlord in each instance which consent shall not be unreasonably conditioned, withheld or delayed.

          

          

          (b)  If this Lease is assigned, or if the Premises or any part thereof is sublet or occupied by anyone other than Tenant, Landlord or Landlord’s Agent may, at any time and from
              time to time, collect Rent and other charges from the assignee, subtenant or occupant, and apply the amount collected to Rent or other charges herein reserved. No such assignment, subletting, occupancy or collection shall be deemed a waiver
              of the covenant against subletting or assignment, or the acceptance  of the assignee, subtenant or occupant as a tenant or a release of Tenant from the further performance by Tenant of its obligations hereunder. At all times Tenant shall
              remain liable for the payment of all Base Rent, Escalation Charges and other charges due hereunder, and for the full performance of the covenants and conditions of this Lease, regardless of whether Premises are occupied by Tenant, vacant
              during the Term of this Lease or occupied pursuant to an assignment or sublease to which the Landlord has consented.

          (i) Tenant’s request for Landlord’s consent to subletting or assigning any portion of the Premises shall be submitted in writing. Such written request shall
              state the following information regarding prospective subtenants or assignees: name of individual(s), name of company, occupation or type of business, prior business address. Landlord may request, either verbally or in writing, additional
              reasonable information regarding prospective subtenants. Landlord shall have seven (7) business days after all requested information has been provided to consent to such sublease or assignment. If Landlord has not responded within fourteen
              (14) business days after all requested information has been provided for such consent, it is therefore understood that Landlord has consented. Landlord hereby consents to the Approved Subtenants occupying less than the entire Premises listed
              in Section 1.1 of this Lease. No prior Landlord approval of assigning or subletting shall be required if such assigning or subletting is to any parent company or wholly- owned subsidiary of Tenant.

           

          (ii) Tenant’s request for Landlord’s consent to subletting or assigning the entire Premises shall be submitted in writing. Such written request shall state
              the following information regarding prospective assignees or subtenants: name of individual(s), name of company, occupation or type of business, prior business address. Landlord may re quest, either verbally or in writing, additional
              information regarding prospective assignees or subtenants. Landlord’s consent shall be granted only if the assignee or subtenant shall agree to pay Landlord Rent, including Additional Rent at 100% of that reserved in this Lease. It shall not
              be deemed unreasonable for Landlord to withhold consent to Tenant’s request to sublet or assign the entire Premises if (y) Landlord is actively negotiating with a prospective assignee or subtenant for another space in the Building or (z) the
              prospective assignee or subtenant is at such time a tenant in the Building. Landlord shall have thirty (30) days after all requested information has been provided to consent to such assignment or sublease. No prior Landlord approval of
              assigning or subletting shall be required if such assigning or subletting is to any parent company, any subsidiary of any parent company, or wholly-owned subsidiary of Tenant or parent company.

           

          (c) If Landlord consents to such assignment or subletting of the Premises, it is understood and agreed that fifty percent (50%) of all amounts, less Tenant’s reasonable
              subleasing costs (which shall include, but not be limited to attorney fees, brokerage commissions, tenant improvements, and free rent), including any lump sum or installment payments paid to Tenant in excess of the Base Rent, Escalation
              Charges and other charges due to Landlord hereunder shall also be paid to Landlord.

           

          (d) If Landlord consents to such assignment or subletting, Tenant will pay to Landlord all costs associated with signage, parking permits, or any other costs associated with
              Tenant’s subtenant or assignee. Such costs shall be due as specified in Section 3.l.

           

          (e) Notwithstanding anything contained herein to the contrary and without limiting the generality of Paragraph 6.1 (a), it shall not be deemed unreasonable for Landlord to
              withhold its consent if the Tenant is or has been in default beyond applicable cure periods under the terms of this Lease, has not provided to Landlord information requested by Landlord pursuant to Section 6.1(c), is proposing to assign or
              sublet to any assignee or subtenant or other occupant who is an existing tenant at the Property or is in discussions with Landlord regarding space in the Property being offered by the Landlord for rent to the market, or is proposing to assign
              or sublet to any assignee or subtenant or other occupant whose financial status, character, method of doing business and/or proposed use or occupancy of the Premises or any other part of the Building would adversely affect the character or
              value of the Building, and, in the event of subleasing or assigning the entire Premises, whose financial status is not substantially the same as, or better than, that of the Tenant.

          Landlord shall not be responsible to make any improvements or repairs to the Premises, except for repairs to structural, roof, mechanical, plumbing, life safety and electrical
              systems located within and serving the Premises, including exterior windows, and those specified in  Exhibit C “Landlord’s Work.” Tenant shall be conclusively deemed to have agreed that Landlord has performed all of its obligations under
              Exhibit C unless not later thirty (30) days after the Commencement Date Tenant shall give Landlord written notice specifying the respects in which Landlord has not performed any such obligation.

                  TENANT’S REPAIR AND MAINTENANCE

                


           

          (a)  Tenant shall keep the Premises neat and clean and maintain the Premises together with all electrical and mechanical fixtures, fittings and appurtenances therein in good
              order, condition and repair (including, without limitation, tenant entry doors, interior window glass and every part thereof, but excepting Landlord’s responsibilities under Section 7.1), except as a result of reasonable wear and tear of the
              Premises, damage by fire or other casualty or as a consequence of eminent domain. Tenant acknowledges that, subject to the completion of the improvements and repairs specified in Exhibit C “Landlord’s Work” for the Premises, the Premises are
              now in good order and the glass whole. Tenant shall maintain and use the Premises in accordance with all applicable laws, rules, regulations and ordinances and shall, at Tenant’s expense, obtain all permits, licenses and the like required by
              applicable law in connection with such maintenance and use. Tenant shall be responsible for the cost of any repairs made necessary  by reason of damage  to the Building by Tenant or Tenant’s independent contractors. Tenant shall be
              responsible for the cost of materials and labor for any repairs pursuant to this Section 7.2 performed by Landlord at the request of Tenant. Tenant shall be responsible for the cost of routine repair of lighting fixtures located within and
              exclusively serving the Premises, including ballasts and bulbs, (the “Lighting Fixtures”) after six (6) months following the Commencement Date. All Lighting Fixtures shall be working at the Expiration Date. All such costs due from Tenant
              shall be due and paid  by Tenant as Rent.

           

          (b) If repairs are required to be made by Tenant pursuant to this Lease, Landlord may require that Tenant make such repairs immediately and if Tenant refuses or neglects to
              commence such repairs and complete the same with reasonable diligence after such demand, Landlord shall have the right but not the obligation to make or cause such repairs to be made at Tenant’s expense and shall not be responsible to Tenant
              for any loss or damage that may accrue to Tenant’s property or business by reason thereof. Any cost or expense reasonably incurred by Landlord in connection with such repairs shall become part of the Rent and shall  be due and payable in full
              with the next payment of Rent.

                  TENANT’S EQUIPMENT

                


           

          Tenant shall not place any fixtures, machinery, equipment or the like (“Tenant’s Equipment”) upon any floor in the Premises exceeding the floor load per square of area which the
              floor was designed to carry and which is permitted by applicable law. Landlord reserves the right to approve the weight or position of any such items so as to properly distribute the weight. Business machines and equipment shall be placed and
              maintained in such settings as are sufficient, in Landlord’s reasonable judgment, to absorb and prevent vibration, noise and annoyance. Tenant shall provide safety cabinets for any hazardous materials located in the Premises. Any hazardous
              materials must be delivered to the loading dock of the Building and be immediately delivered to the Premises. Pallet movers are not allowed in the Common Areas and pallets must be broken down in the loading dock.

           

          Within thirty (30) days of the final sign-off of the City of Cambridge Inspectional Services building inspector for the completion of improvements in the Premises, Tenant shall
              provide Landlord with a list of the items installed by Tenant with equipment specified by  manufacturer, tonnage or BTU’s, model number, serial number, location in the Premises or on Building’s roof and year installed. Tenant shall provide
              Landlord with updated equipment lists throughout the Term as additional HYAC equipment is installed, upgraded or replaced with equipment specified by manufacturer, tonnage or BTU’s, model number, serial number, location in the Premises or on
              Building’s roof and year installed.

          (i)  Utilities for the Premises. For the Premises, Tenant shall pay, as they become due, all
              bills for electricity (whether used for air conditioning, heat, lights, outlets or other purposes) that are furnished to the Premises and separately metered. Tenant agrees to contact the provider of electrical services to the Premises’
              previous tenant or to Landlord immediately after the Commencement Date and to place the electric meter and its account into the Tenant’s name. In the event that Tenant fails to transfer the meter to Tenant, then Landlord may transfer the
              account into the Tenant’s name or should such transfer by Landlord be unsuccessful, Landlord may place Tenant in default under Section 13.1 (ii) of this Lease. Landlord may determine, in its sole discretion, to transfer any or all utilities,
              including those utilities paid for by Tenant, to other public or private vendors of utilities and if such transfer is made, Landlord shall provide advance written notice thereof.

           

          (ii)  Landlord may determine, in its reasonable discretion, to transfer any or all utilities, including those utilities paid for by Tenant, to other public or
              private vendors of utilities and if such transfer is made, Landlord shall provide advance written notice thereof.

           

          (b) COMMON AREAS. Tenant shall have 24 hours per day, seven days per week and 52 weeks per year access to the Premises, and appropriate
              common areas of the Building, Condominium and Property.

           

          (c) HEATING AND OTHER SERVICES. Landlord agrees to provide reasonable heat and air conditioning to the Premises during Business Hours
              on Business Days of the heating and air conditioning seasons of each year with the existing 7.5-ton rooftop unit. Land lord shall have no obligation to provide utilities or equipment other than the utilities and equipment within the Premises
              or serving the Premises as of the Commencement Date. The installation of additional heating and air conditioning equipment powered by electricity or gas after the Commencement Date and the maintenance of such equipment located and used wholly
              within the Premises shall be Tenant’s sole obligation, provided that such installation shall be subject to the written consent of Landlord, which shall not be unreasonably delayed or withheld.

          In the event Taxes shall be greater during any Tax Year than Base Taxes, Tenant shall pay to Landlord, as an Escalation Charge, an amount equal to (i) the excess of Taxes over
              Base Taxes, multiplied by (ii) the Escalation Percentage (“Real Estate Tax Payments”). Amounts payable by Tenant according to this section will be payable as Rent, without deduction or offset. If Tenant fails to pay any amounts due according
              to this section, Landlord will have all rights and remedies available to it on account of Tenant’s failure to pay Base Rent. In the event that the Term has expired and Landlord reasonably expects that Tenant shall be required to pay Real
              Estate Tax Payments applicable to the term in excess of Estimated Real Estate Payments, then Landlord may retain that portion of the Security Deposit which Landlord reasonably expects shall be equal to Real Estate Tax Payments for the last
              Lease Year and upon final reconciliation, Landlord shall release any Security Deposit not required for Real Estate Tax Payments. Notwithstanding the previous sentence, Tenant shall remain liable for unpaid Real Estate Tax Payments applicable 
              to the term after the Expiration Date.

                  ABATEMENT

                


           

          If Landlord shall receive any tax refund or reimbursement of taxes or sum in lieu thereof with respect to any Tax Year, then, out of any balance remaining after deduction for
              Landlord’s reasonable expenses incurred in obtaining such abatement, Landlord shall pay to Tenant, provided there does not exist an uncured Default of Tenant, an amount equal to such sum (exclusive of any interest paid on the abatement)
              multiplied by the Escalation Percentage. In no event shall Tenant be entitled to receive more than the payments made by Tenant on account of real estate taxes for such Tax Year pursuant to Section 8.1, or to receive any payment or abatement
              of Base Rent if Taxes for any year are less than Base Taxes or Base Taxes are abated.

           

          	8.3	
                  ESTIMATED REAL ESTATE TAX PAYMENTS

                


           

          Landlord may, from time to time, reasonably estimate Tenant’s Real Estate Tax Payments with respect to any Tax Year or portion thereof and Tenant shall pay periodically as Land
              lord may determine, but not more frequently than monthly, the amount of Landlord’s estimate as Rent. Not later than 120 days after the end of each calendar year, Landlord will deliver to Tenant a statement of amounts payable under Section 8.1
              for such calendar year and any amount due from Tenant or any credit due to Tenant hereunder. Payment by Tenant of any amount due shall be made as Rent with Tenant’s next payment of Base Rent. Landlord shall credit the amount of any
              overpayment against subsequent obligations of Tenant. If the Term has expired and Tenant was not in default, Landlord will refund the overpayment to Tenant.

          In the event Condominium Fees shall be greater during any Operating Year than Base Condominium Fees, Tenant shall pay to Landlord, as an Escalation Charge, an amount equal to
              (i) the excess of Condominium Fees over Base Condominium Fees, multiplied by (ii) the Escalation Percentage (“Condominium Fee Payments”). Amounts payable by Tenant according to this section will be payable as Rent, without deduction or
              offset. If Tenant fails to pay any amounts due according to this section, Landlord will have all rights and remedies available to it on account of Tenant’s failure to pay Base Rent. In the event that the Term has expired and Landlord
              reasonably expects that Tenant shall be required to pay Condominium Fee Payments in excess of Estimated Condominium Fee Payments, then Landlord may retain that portion of the Security Deposit which Landlord reasonably expects shall be equal
              to Condominium Fee Payments for the last Lease Year and upon final reconciliation, Landlord shall release any Security Deposit not required for Condominium Fee Payments. Notwithstanding the previous sentence, Tenant shall remain liable for
              Condominium Fee Payments applicable to the Term after the Expiration Date. No Condominium Fee Payments shall be due for lease periods prior to the Commencement Date.

          Landlord may, from time to time, reasonably estimate Tenant’s Condominium Fee Payments with respect to any calendar year or portion thereof and Tenant shall pay periodically as
              Landlord may determine, but not more frequently than monthly, the amount of Landlord’s estimate as Rent. Not later than 120 days after the end of each calendar year, Landlord will deliver to Tenant a statement of Condominium Fees and any
              amounts payable under Section 9.1 for such calendar year and any amount due from Tenant or any credit due to Tenant hereunder. Payment by Tenant of any amount due shall be made as Rent with Tenant’s next payment of Base Rent. Landlord shall
              credit the amount of any overpayment against subsequent obligations of Tenant. If the Term has expired and Tenant has no uncured defaults, Landlord will refund the overpayment to Tenant.

          Landlord and Landlord’s Agent shall have the right to enter the Premises upon reasonable oral notice (except in the case of emergency for which no notice shall be required) for
              the purposes of inspecting the Premises and making repairs to the same. Upon reasonable notice, Landlord and Landlord’s Agent shall also have the right to make access available at all reasonable hours to prospective or existing mortgagees,
              purchasers or tenants of any part of the Property provided, however, that no such entry shall materially interfere with or materially obstruct the Tenant’s use of the Premises or the conduct of its business from the Premises. Landlord and
              Landlord’s Agent will at all times have and retain keys with which to unlock all of the doors in the Premises (excluding Tenant’s vaults, safes, and similar areas designated in writing by Tenant in advance).

                  ABATEMENT OF RENT

                


           

          If the Premises shall be damaged by fire or casualty, Base Rent and Escalation  Charges payable by Tenant shall abate proportionately for the period in which, by reason of such
              damage, there is substantial interference with Tenant’s use of the Premises, having regard to the extent to which Tenant may be required to discontinue Tenant’s use of all or a portion of the Premises, but such abatement or reduction shall
              end if when Landlord shall have substantially restored the Premises  to the condition in which they were prior to such damage. If the Premises shall be affected by any exercise of eminent domain, Base Rent and Escalation Charges payable by
              Tenant shall be justly and equitably abated and reduced according to the nature and extent of the loss of use thereof suffered by Tenant.

                  RIGHT TO TERMlNATE

                


           

          (a)   If the Premises or Tenant’s access to the Premises, or the Building arc substantially damaged by fire or other casualty to the extent that such Premises or Building
              cannot, in the ordinary course, reasonably be expected to be repaired within ninety (90) days from the time of such fire or casualty, or if any part of the Building is taken by the exercise of eminent domain, then Landlord may, at Landlord’s
              option terminate this Lease by giving written notice to Tenant within sixty (60) days following the occurrence of such fire or other casualty or the effective date of such taking, whereupon this Lease shall terminate thirty (30) days after
              the date of such notice.

              such damage cannot for any reason, in the ordinary course, be substantially repaired within ninety (90) days from the time of fire or casualty, or if any substantial portion of the Premises is taken by the exercise of eminent domain, Tenant
              shall have the right to terminate this Lease by giving written notice to Landlord within sixty (60) days following the occurrence of such fire or other casualty or the effective date of such taking, whereupon this Lease shall terminate thirty
              (30) days after the date of such notice.

                  RESTORATION

                


           

          If this lease is not terminated pursuant to Section 12.2, Landlord shall use reasonable diligence to restore the Premises to proper condition for Tenant’s use provided that
              Landlord’s obligation shall be limited to the amow1t of insurance proceeds available to Landlord for such restoration. If, for any reason, such restoration shall not be substantially completed, or the Premises is not substantially restored to
              proper condition for Tenant’s use as it was prior to such damage, within six (6) months subject to any extension for such periods of time as Landlord is prevented from completing such restoration due to any cause beyond Landlord’s reasonable
              control after the expiration of the ninety (90) day period referred to in Section 12.2, Tenant shall have the right to terminate this Lease by giving written notice to Landlord within thirty (30) days after the termination of such period (as
              such as may have been extended above). Upon the giving of such notice, this Lease shall terminate on the thirtieth (30th) day following Landlord’s receipt  of Tenant’s notice without further liability or obligation on the part of either party
              unless, within such thirty (30) day period, Landlord substantially completes such restoration. Such right of termination shall be Tenant’s sole and exclusive remedy for Landlord’s failure to complete restoration.

              leasehold interest hereby created, and to compensation accrued or hereafter to accrue by reason of taking, damage or destruction and by way of confirming the foregoing, Tenant hereby grants and assigns, and covenants with Landlord to grant
              and assign to Landlord, all rights to such damages or compensation. Nothing contained herein shall be construed to prevent Tenant from prosecuting in any condemnation proceedings a claim for the value of any of Tenant’s Removable Property
              installed in Premises by Tenant at Tenant’s expense and for relocation expenses, provided that such action shall not affect the amount of compensation otherwise recoverable by Landlord from the taking authority. The provisions of this Section
              12.4 shall not apply to any rights of Tenant to recover for damages or compensation relating to Tenant’s Removable Property.

                  If during the Term of this Lease any of the following events shall occur:

                


           

          (i)  Tenant shall fail to pay Base Rent, Escalation Charges or other charges hereunder when due, and shall have failed to cure such deficiency within ten (10)
              days of the date that Landlord shall have sent written notice to Tenant via in -hand delivery, receipt from Federal Express (or other express mail service) or the receipt of certified mail of such failure. Notwithstanding the foregoing, if
              Landlord shall have sent to Tenant a notice of any such failure three times during any twelve month period, and even though such failures may have been cured during the ten (10) day cure period, any subsequent failure to make payment during
              such a twelve month period shall be deemed to be a default without any notice from Landlord, and for which the Landlord shall not be required to recognize any period during which such failure may be cured; or

          

          
            17

            
              


          

          (ii)  Tenant shall neglect or fail to perform or observe any other covenant contained in this Lease and Tenant shall fail to remedy the same within thirty
              (30) days after receipt of a written notice to Tenant via Federal Express (or other express mail service) or by certified mail specifying such neglect or failure, or if such failure is of such a nature that Tenant cannot reasonably remedy the
              same within such thirty (30) day period, Tenant shall fail to commence promptly, within such 30 day period, to remedy the same and to prosecute such remedy to completion with diligence and continuity, provided that such cure shall be
              completed in any event within ninety (90) days of written notice, unless such period is extended in writing by Landlord; or

           

          (iii) Tenant’s leasehold interest in the Premises shall be taken on execution or by other process of law directed against Tenant; or

           

          (iv)  Tenant shall make an assignment for the benefit of creditors; or shall file a voluntary petition in bankruptcy; or shall be adjudicated bankrupt or
              insolvent, or shall file any petition or answer seeking any reorganization, arrangement, composition, readjustment, liquidation, dissolution or similar relief for itself under any present or future Federal, State or other statute, law or
              regulation for relief of debtors; or shall seek or consent to or acquiesce in the appointment of any trustee, receiver or liquidator of Tenant or of all or a substantial part of its properties; or Tenant shall admit in writing its inability
              to pay its debts generally as they become due; or

           

          (v)  a petition shall be filed against Tenant in bankruptcy or under any other law seeking any reorganization, arrangement, composition, readjustment,
              liquidation, dissolution or similar relief under any present or future Federal, State or other statute, law or regulation and shall remain undismissed or unstayed for an aggregate of sixty (60) days; or if any debtor in possession, trustee
              receiver or liquidator of Tenant or of all or a substantial part of its properties or of the Premises shall be appointed without the consent or acquiescence of Tenant, and such appointment shall remain unvacated or unstayed for an aggregate
              of sixty (60) days;

           

          then in any such case:

           

          (1) If such Default by Tenant, other than subsection (vi), shall occur prior to the Commencement Date, Landlord may, without further act on the part of
              Landlord, terminate this Lease by written notice to Tenant, and

           

          (2) If such Default by Tenant shall occur after the Commencement Date, Landlord may terminate this Lease by written notice as provided to Tenant and this
              Lease shall come to an end on the date specified therein and Tenant will then quit and surrender the Premises to Landlord, but Tenant shall remain liable as hereinafter provided.

            (b) If this Lease is terminated as provided in this Lease, or if any execution or attachment shall be issued against Tenant or any of Tenant’s property whereupon the Premises shall be taken or occupied
                by someone other than Tenant, then Landlord may, thereafter, without notice, re-enter the Premises, either by summary proceedings, ejectment or otherwise, and remove and dispossess Tenant and all other persons and any and all property from
                the same, as if this lease had not been made and Tenant hereby waives the service of notice of intention to re-enter or to institute legal proceedings to that end.

          

           

          (c) In the event of any termination for Default by Tenant, Tenant shall remain responsible for the Base Rent, Escalation Charges and other charges payable hereunder, up to the
              date of the termination, and thereafter Tenant, until the end of what would have been the end of the Term in the absence of such termination whether or not the Premises shall have been re-let, shall be liable to Landlord for and shall pay to
              Landlord, as liquidated current damages, the Base Rent, Escalation Charges and other charges which would be payable hereunder if such termination had not occurred, less the net proceeds, if any, of any re-letting of the Premises, after
              deducting all expenses in connection with such re-letting, including, without limitation, all repossession costs, including attorney fees incurred in seeking possession or unpaid charges, brokerage commissions, legal expenses, reasonable
              alteration costs and expenses of preparation for re-letting Tenant shall pay such Base Rent, Escalation Charges and other charges to Landlord monthly on the days on which the Base Rent would have been payable hereunder if this Lease had not
              been terminated.

           

          (d) At any time after such termination, whether or not Landlord shall have collected any post termination charges, as liquidated final damages and in lieu of all damages beyond
              the date of such demand, at Landlord’s election, Tenant shall pay to Landlord an amount equal to the excess, if any, of the present value (at a discount rate of 10%) of the Base Rent, Escalation Charges and other charges as herein before
              provided which would be payable hereunder from the date of such demand (assuming that, for the purposes of this paragraph, annual payments by Tenant on account of Taxes and Operating Expenses would be the same as the payments required for the
              immediately preceding Operating Year or Tax Year) for what would be the then unexpired Term of this Lease  if the same remained in effect, over the present value (at a discount rate of 10%) of the then fair net rental value of the Premises
              for the same period. In no event shall Tenant be obligated to pay any more pursuant to this subparagraph (d) than Tenant would have been required to pay under this Lease absent such default.

           

          
            
              (e) In the case of any Default by Tenant, re-entry, expiration and dispossession of Tenant by summary proceedings or otherwise, Landlord may:

            

          

          

          (i)  re-let the Premises or any part thereof, either in the name of Landlord or otherwise, for a term or terms which may at Landlord’s option be equal to or
              less than or exceed the period which would otherwise have constituted the balance of the Term of this Lease and may grant concessions of free rent to the extent that Landlord considers reasonably advisable and necessary to re-let the
              Premises; and

           

          (ii)  may make such reasonable alterations, repairs and decorations in the Premises as Landlord in its reasonable judgment deems advisable and necessary for
              the re-letting of the Premises. Any such repairs, decorations or alterations shall not operate nor be construed to release Tenant from any liability under this lease.

           

            

          
            19

            
              


          

          Landlord will use best efforts to, but in no event be liable in any way for failure to re-let the Premises, or, in the event that the Premises are re-let, for failure to collect
              the rent under such re-letting. Tenant expressly waives any and all rights of redemption granted by or 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.

           

          (f) The specified remedies to which Landlord may resort are not intended to be exclusive of any remedies or means or redress to which Landlord may at any time be entitled
              lawfully, and Landlord may invoke any remedy (including the remedy of specific performance) allowed at law or in equity as if specific remedies were not herein provided for.

           

          
            (g) Upon Default by Tenant, or the expiration or termination of this Lease, Landlord shall have the right of summary process under any applicable statutes and such other rights to recover possession as
                permitted by law. Tenant and Landlord each hereby waive any and all rights under the law of any state to the right, if any, to trial by jury.

          Landlord shall in no event be in default in the performance of any of Landlord’s obligations hereunder unless and until Landlord shall have failed to perform such obligations

                  WAIVER

                


           

          (a)  Failure on the part of Landlord or Tenant to complain of any action or non-action on the part of the other, no matter how long the same may continue, shall never be a
              waiver by Tenant or Landlord, respectively, of any of the other’s rights hereunder. Further, no express waiver at any time of any of the provisions thereof by Landlord or Tenant shall be construed as a waiver of any of the other provisions
              hereof nor shall it be construed as a waiver at any subsequent time of the same provisions. The consent or approval of Landlord or Tenant to or of any action by the other requiring consent or approval shall not be construed to waive or render
              unnecessary Landlord’s or Tenant’s consent or approval to or of any subsequent similar act by the other.

           

          (b) No payment by Tenant, or acceptance by Landlord, of a lesser amount than shall be due from Tenant to Landlord shall be treated otherwise than as a payment on account. The
              acceptance by Landlord of a check for a lesser amount with an endorsement or statement thereon, or upon any letter accompanying such check, that such lesser amount is payment in full, shall be given no effect, and Landlord may accept such
              check without prejudice to any other rights or remedies which Landlord may have against Tenant.

                  COVENANT OF QUIET ENJOYMENT

                


           

          Tenant, subject to the terms of this Lease, of payment of the Base Rent, Escalation Charges and other charges due hereunder and observing, keeping and performing all of the
              other terms and provisions of this Lease on Tenant’s part to be observed, kept and performed, shall lawfully, peaceably and quietly have, hold, occupy and enjoy the Premises during the Term, without hindrance or ejection by any persons
              lawfully claiming to have title to the Premises superior to Tenant. This covenant of Quiet Enjoyment is given in lieu of any other covenant, express or implied.

                  LANDLORD’S LIABILITY

                


          

          

          (a)  With respect to the Landlord’s obligations under this Lease, Tenant specifically agrees to look solely to Landlord’s interest in the Property at the time of award of any
              judgment, for recovery of any such judgment against Landlord. It is specifically understood and agreed that neither Landlord nor any Manager or Member thereof shall ever be personally liable for any such judgment, or for the payment of any
              such monetary obligation to Tenant. This provision is not intended to, and shall not, limit any right Tenant might otherwise have to obtain injunctive relief against Landlord or Landlord’s successors in interest, or to take any action not
              involving the personal liability of Landlord.

           

          (b) With respect to any services to be furnished by Landlord to Tenant, Landlord shall in no event be liable for failure to furnish the same when prevented from doing so by
              strike, lockout, breakdown, accident, order or regulation of or by any governmental authority, or failure of supply, or inability by the exercise of reasonable diligence to obtain supplies, parts or employees necessary to furnish such
              services, or because of war, civil disturbance, or other emergency, or for any cause beyond the reasonable control of Landlord, or for any other cause due to any act or neglect of Tenant or Tenant’s servants, agents, employees, licensees or
              any person claiming by, through or under the Tenant.

                  TRANSFER OF TITLE

                


           

          A sale, conveyance or assignment of the Property will operate to release Landlord from liability from and after the effective date of such sale, conveyance or assignment upon
              all of the covenants, terms and conditions of this Lease, express or imp lied, except those liabilities which arose prior to such effective date, and, after the effective date of such sale, conveyance or assignment, Tenant will look solely to
              Landlord’s successor in interest in and to this Lease.

           

          	14.5	
                  RULES AND REGULATIONS

                


           

          In addition to the Rules and Regulations of the Condominium Trust listed in Exhibit F, Tenant shall abide by rules and regulations reasonably established from time to time by
              Landlord and Landlord’s Agent, it being agreed that such rules and regulations will be established  and applied by Landlord and Landlord’s Agent in a non-discriminatory fashion, such that all rules and regulations shall be generally
              applicable to other Tenants of similar nature to Tenant, and do not materially interfere with Tenant’s use. Landlord and Landlord’s Agent agrees to use reasonable efforts to ensure that any such rules and regulations are uniformly enforced,
              but Landlord and Landlord’s Agent shall not be liable to Tenant for violation of the same by any other Tenant or occupant of the Building, or persons having business with them. Initial rules and regulations are attached as Exhibit D, “Rules
              and Regulations for Fairlane Columbia, LLC.”

                  ADDITIONAL CHARGES

                


           

          If Tenant shall fail to pay when due any sums under this Lease, Landlord shall have the same rights and remedies as Landlord has hereunder for failure to pay Base Rent.

           

          	14.7	
                  SEVERABILITY

                


           

          If any term of this Lease, or the application thereof to any person or circumstance shall, to the extent, be invalid or unenforceable, the remainder of this Lease, or the
              application of such term to persons or circumstances other than those to which it is held invalid or unenforceable, shall not be affected thereby, and each terms and provision of this Lease shall be valid and be enforced to the fullest extent
              permitted by law.

           

          	14.8	
                  BINDING NATURE

                


           

          Except as set forth  herein  to the contrary, the terms of this Lease shall be binding upon and shall inure to the benefit of the successor and assigns, respectively, of
              Landlord and Tenant and, if Tenant shall be an individual, upon and to his heirs, executors, administrators, successors and assigns. Each term to be performed by Tenant shall be construed as both a covenant and a condition. The reference
              contained herein to successors and assigns of Tenant is not intended to constitute a consent to assignment by Tenant, but has reference only to those instances in which Landlord may later give consent to a particular assignment  as required
              by the provisions of Article VI.

           

          	14.9

              Express (or other similar express mail service), registered or certified mail postage to Landlord at the Landlord’s Address, Landlord’s Agent at Landlord’s Agent’s address, or to Tenant at Tenant’s Address, as the case may be. All such

          All understandings between Landlord and Tenant are incorporated herein and this Lease expressly supersedes any proposals or other written documents relating hereto. This Lease
              may be modified or amended only by written agreement between Landlord and Tenant, and no act or omission of any employee or agent of Landlord shall alter, change or modify any of the provisions hereof.

           

          	14.11	
                  SUBORDINATION

                


           

          This Lease shall be subordinate to Massachusetts General Laws Chapter 183A, the Condominium Documents and any mortgage, or other instrument in the nature of a mortgage, from
              time to time encumbering the Premises or the Condominium, whether executed and delivered prior to or subsequent to the date of this Lease, if the holder of such mortgage shall so elect. Tenant agrees to execute such instruments of
              subordination and provide to Landlord within ten (10) business days of Landlord’s written request to Tenant in confirmation of the foregoing agreement as the holder of such mortgage may request, and Tenant hereby irrevocably appoints Landlord
              as Tenant’s attorney-in-fact to execute such subordination agreement upon default of Tenant in complying with the holder of such mortgage’s request.

          Tenant, on the request of Landlord made from time to time, will execute and deliver to Landlord within ten (10) business days of Landlord’s written request to Tenant, a
              statement certifying to the status of any matter pertaining to this Lease, including, without limitation, and if true, (i) that this Lease is unmodified and in full force and effect or, if there have been modifications, (ii) that this Lease
              is in full force and effect as modified, and stating the date and nature of such modifications, (iii) the date, if any, to which Rent and other sums payable under this Lease have been paid, and (iv) such other similar matters as may be

                  LANDLORD’S RIGHT TO CURE DEFAULTS

                


           

          Landlord shall have the right, but shall not be required, to pay such sums or do any act which requires the expenditure of moneys which may be necessary or appropriate by reason
              of the failure or neglect of Tenant to perform any of the provisions of this Lease (after any applicable notice and cure periods provided in this Lease), and in the event of the exercise of such right by Landlord, Tenant agrees to pay to
              Landlord forthwith upon demand all such sums, together with interest thereon at a rate equal to 2% over the Prime Rate in effect and announced from time to time at Bank of America or successor bank at its principal offices located at 100
              Federal Street, Boston, Massachusetts, or any subsequent location of its principal offices in Massachusetts, as an additional charge here under. Any payment of Base Rent, Escalation charges or other sums payable hereunder not paid when due
              shall, at the option of Landlord, bear interest at the Default Rate from the due date thereof and shall be payable forthwith on demand by Landlord as an additional charge hereunder.

                  WAIVER OF SUBROGATION

                


           

          Insofar as, and to the extent that, this provision may be effective without invalidating or making it impossible to secure insurance coverage obtainable from recognized
              insurance companies doing business in the City of Cambridge, Landlord and Tenant mutually agree that, with respect to any hazard, the loss from which is covered by insurance then being carried by them, respectively, the one carrying such
              insurance and suffering such loss releases the other of and from any and all claims with respect to such loss to the extent of the insurance proceeds paid with respect thereto and that their respective insurance companies shall have no
            right of subrogation against the other on account thereof.

              by such removal. Any of Tenant’s Removable Property which shall remain in the Building or on the Premises after the Expiration Date, Termination Date, or earlier termination of the Term of this Lease shall be deemed conclusively to have been

              hereunder. Landlord shall have the right, from time to time, without prejudice to any other remedy Landlord may have on account thereof, to apply such Security Deposit, or any part thereof, to Landlord’s damages arising from any uncured
              Default of Tenant. Provided that there is no uncured Default of Tenant, Landlord shall return the Security Deposit, or so much thereof as shall not have theretofore been applied in accordance with the terms of Section 14.20, to Tenant within

              Landlord holds the Security Deposit, Landlord shall have no obligation to pay interest on the same and shall have the right to commingle the Security Deposit with Landlord’s other funds. If any part of the Security Deposit is applied as
              herein provided, Tenant shall replace same within thirty (30) days of receiving written notice from the Landlord or Landlord’s Agent. Landlord shall deliver the Security Deposit, or any part hereof not previously applied, to the purchaser of
              the Building in the event the Building is sold, whereupon Tenant agrees to look solely to such successor in interest for proper application and return in accordance with the terms of this Section 14.20. The Security Deposit shall not be used
              by Tenant as a payment of Rent due for the last month or any month of the Term.

          Landlord agrees  that  Tenant  may  install  a  satellite  dish/antenna  and  associated  wiring  (the “Equipment”) on the Building’s roof and in the Building’s risers meeting
              the specifications set forth below, subject to the approval of the Condominium Trustees. The Equipment, which shall be included as Tenant’s Removable Property, shall be installed, at Tenant’s sole cost and expense, by a contractor providing
              satisfactory insurance certificates to Landlord and Landlord’s Agent in a location approved in advance by Landlord. Tenant shall obtain all governmental approval and permits required for the installation and operation of the Equipment and
              otherwise perform all work in a good, workmanlike manner and operate the Equipment in compliance with all applicable Federal, state and  local  laws,  ordinances,  statutes,  codes  and  regulations,  including  without limitation, the rules
              and regulations of the Federal Communications Commission. Upon commencement of installation, Tenant shall pay an additional $200.00 per month for the remaining Term for the use of the roof, risers and other Building areas. No satellite dish
              shall exceed twenty-four (24) inches in diameter. The location of a satellite dish/antenna on the roof and location of wiring on the roof, risers and other Building areas are subject to Landlord’s approval. Tenant acknowledges that Landlord
              may have provided licenses to telecommunication companies for satellite dishes and antennas and approval to other tenants for rooftop satellite dishes. A satellite dish used by Tenant must not interfere with the placement or use of satellite
              dishes/antenna for the aforesaid telecommunication companies or tenants. In the event that roof maintenance, repair or replacement requires the relocation or movement of a satellite dish/antenna or temporary loss of reception, Tenant agrees
              to cooperate with Landlord and Landlord’s vendors during the period of such maintenance, repair or replacement.

          Any failure by the Tenant to comply in all respects with the provisions of the Master Deed of the Condominium, the Declaration of Trust and the By-Laws and Rules and Regulations
              thereto shall constitute a material default in this lease, license, or occupancy agreement, and in the event of such default (“Default”), the Trustees of the Condominium Trust shall have the following rights and remedies against both the Unit
              Owner and the Tenant, in addition to all other rights and remedies that Trustees and the Unit Owners (other than the owner of the affected Unit) have or may in the future have, against both the owner of the affected Unit and the tenant, all
              rights and remedies of the Trustees and the Unit Owners (other than the owner of the affected Unit) being deemed at all times to be cumulative and not exclusive. In addition,

           

          (i)  The Trustees shall have the right to give written notice of the Default to both the Tenant and the Unit Owner. Said notice shall be deemed properly given
              if left in any part of the Unit, addressed to the Tenant, and mailed postage pre-paid, registered or certified mail, return receipt requested, addressed to the Unit Owner at such address as appears on the records of the Trustees, or by
              delivering said notice in hand, or be delivering said notice in any other manner permitted by law.

           

          (ii)  If the Default continues for five days after the giving of said notice, then the Trustees shall have the right to levy fines against the Unit Owner in
              accordance with the By-Laws, and terminate the tenancy by giving notice in writing to quit to the Tenant in any manner permitted by the Trustees, or both. A copy of such notice shall be delivered or mailed to the Unit Owner in the manner set
              forth hereinabove. Thereafter, the Trustees may initiate and prosecute a summary process action against the Tenant under the provisions of Massachusetts General Laws, in the name of the Unit Owner or in the name of the Trustees, or both.

           

          (iii) The Trustees shall be entitled to levy a fine or fines, or give a notice or notices to quit, followed by a summary process action or actions, and the
              Trustees’ election to pursue any of the foregoing remedies shall in no way prohibit them from pursuing all of the foregoing remedies, either at the same time, or in the event of any further default.

           

          (iv) All of the expenses incurred by the Trustees in giving notices, and notices to quit and maintaining and pursuing summary process actions and appeals
              therefrom, shall be entirely at the expense of the Unit Owner of the affected unit. Such costs and expenses may be enforced and collected against the Unit Owner and Unit as if the same were common charges owed by the Unit Owner.

          

          

          (v) The Unit Owner shall make reasonable efforts, at his or her expense and upon his or her initiative, to inform rental agents of the provisions of this
              section and shall, at his or her expense, and upon his or her initiative, furnish copies of the Condominium Documents to the Tenant and cause the lease or occupancy agreement to be prepared in conformity with the provisions of this section.

           

            

          
            27

            
              


          

          (vi)  Any renewal or extension of any lease or occupancy agreement shall be subject to the prior written approval of the Trustees in every in stance. Such
              approval shall not limit any rights or remedies of the Trustees or Unit Owners in the event of a subsequent default.

           

          (vii)  A true copy of every lease or occupancy agreement shall be delivered to the Trustees forthwith upon its execution.

           

          (viii)  Notwithstanding anything to the contrary herein, and notwithstanding any custom, law or usage to the contrary, it is expressly understood and agreed
              that neither the Trustees, nor the Unit Owners shall ever bear any personal liability with respect to any lease or the use and occupancy of a unit by a Tenant.

           

          (ix)   Every lease, license or occupancy agreement, shall have attached thereto, and incorporated therein by reference, a copy of this section 5.0 of the
              Rules and Regulations.”

           

          The Condominium Trust Rules and Regulations also require that Landlord inform tenants that:

           

          “If a tenant offers any of its employees parking in the Parking Lot, then the tenant has the option of charging such employee market
              rate for parking, or, alternatively, if the tenant charges any of its employees less than the current monthly market rate for parking, then the tenant will offer such employees an equivalent monthly payment to support the employee’s commute
              by walking, biking, transit or carpool. In the event that an employee chooses to use the equivalent monthly payment for transit, tenants will use best efforts to enroll in the

                MBTA pass grogram to provide an employee with the ability to purchase a pass using pre-tax wages. ‘Equivalent monthly payment’ means the remainder of the current monthly
              market rate for parking less the fee paid for parking by an employee. For example, if the current monthly market rate is $200 and an employee is being charged $50 per month by the employer, then the equivalent monthly payment equals $150 per
              month. Any tenant may charge certain employees for parking at market rate in the Parking Lot and other employees may be charged at less than the current monthly market rate for parking in the Parking Lot with the tenant providing such
              employees with the equivalent monthly benefit option.”

                                  request by Tenant for payment with a calculation of payments in relation to the total Tenant’s Allowance. Tenant’s request for the Final Payment, which shall be in an amount of no less than $5,000.00 and shall also be

                              approval, which may not be unreasonably withheld, delayed or conditioned, within five (5) business days of the submission of the Plans to Landlord. Landlord shall notify Tenant of any objection to the Plans within the
                              abovementioned five (5) business days. Should Landlord not notify Tenant of any objection to the Plans within the abovementioned five (5) business days, such Plans shall be deemed approved by Landlord. Should Landlord notify
                              Tenant of any objection to the Plans within the abovementioned five (5) business days, Tenant shall make revisions and resubmit the plans for Landlord’s approval, whereupon the foregoing review and approval shall be repeated
                              until the Plans are approved (or deemed approved) by Landlord in accordance with this Paragraph B. No review or approval by Landlord of the Plans shall constitute any representation or warranty as to the adequacy, correctness,
                              efficiency or compliance with any laws, regulations or ordinances, or any other aspect of such drawings and specifications. The Plans shall be incorporated by reference into this Exhibit C and Tenant shall provide Landlord

                                shall be the responsibility of Tenant. Tenant shall perform New Lab Tenant Improvements in such a manner as not to interfere with the use and enjoyment of the remainder of the Building by any other tenant or any other
                                construction then being performed by any other tenant or by Landlord. Tenant shall have access to the New Lab Premises as of the date of Lease execution after receipt by Landlord of Tenant’s and Tenant’s Contractor’s
                                Insurance Coverage required under Section H below, provided, however, that Tenant assumes any risks attendant on its entry into the New Lab Premises prior to the completion of the New Lab Tenant Improvements. Tenant’s entry,
                                as described above, shall not be deemed to be occupancy of the Premises. Tenant shall comply with all of the terms, covenants, and conditions of the Lease after the date of Lease execution.

                              Tenant’s Consultants. Tenant shall separately contract with any consultants or engineers for laboratory-specific plumbing, heating, ventilation or air conditioning, or electrical items during construction or during
                                planning of construction. Tenant shall provide Landlord with all specifications and studies provided to Tenant by Tenant’s Consultants.

                              Landlord’s Oversight. Landlord and its agents may have unrestricted access at their own risk to the New Lab Premises during construction. Landlord shall provide a punch list containing
                                specific detailed deficiencies to Tenant within thirty (30) days of the substantial completion of the New Lab Tenant Improvements to correct all said deficiencies noted by Landlord in the New Lab Tenant Improvements to the
                                extent that the New Lab Tenant Improvements do not substantially conform to the approved Plans or if Building Common Areas require corrective action. Tenant shall complete such corrections within a reasonable time, but in no
                                event later than thirty (30) days of the presentation of the punch list to Tenant. Landlord’s punchlist or supervision or approval shall not constitute a warranty that the New Lab Tenant Improvements were properly performed
                                or designed or create any liability for payment for such work by Landlord.

                              Tenant’s Vendors. New Lab Tenant Improvements may be performed only by licensed contractors or subcontractors approved in advance by Landlord; such approval shall not be unreasonably
                                withheld. Tenant shall provide its contract with its general contractor or construction manager prior to the submission of Plans to the City of Cambridge (the “Contract”). With respect to New Lab Tenant Improvements to the
                                life safety system, Landlord reserves the right to require Tenant to use Landlord’s contractors (“Landlord’s Contractors”) to perform such Tenant Improvements, but in such event the charges of such contractors shall be
                                competitive with the charges of other contractors performing similar work in similar office buildings (i.e. - Tenant’s Contractor’s subcontractors (the “subcontractors”)) in the City of Cambridge. In the event that the
                                subcontractors provide pricing below that of Landlord’s Contractors, Tenant shall provide Landlord with the subcontractors’ bids so that Landlord and Tenant’s general contractor may negotiate competitive pricing from
                                Landlord’s Contractors. Landlord’s Contractors will perform all work for Tenant’s Contractor and will not have any contract, oral or written, express or implied, with Landlord for work according to the Plans. Tenant’s
                                vendors shall work with Landlord on the timing of work which may unreasonably disrupt tenants of space adjoining, above and below the New Lab Premises so long as access by such vendors is not unduly restricted and the
                                performance of New Lab Tenant Improvements is not materially delayed.

                              Use of the Building and Parking Lot. Prior to the Commencement Date and during construction of the New Lab Premises, Tenant’s Contractor, subcontractors, engineer and architect may park in
                                Tenant’s Parking Spaces in the Parking Lot and in no other spaces. Tenant’s contractors, subcontractors, engineer and architect may not park in the Building’s visitor spaces. Construction dumpsters may be placed in
                                designated areas of the Parking Lot or along Windsor Street. Dumpster pick-up, for dumpsters placed in the Parking Lot, must occur prior to 8AM on Business Days of the Property. Upon receipt of a Certificate of Insurance as
                                provided in Section H below, Tenant’s Contractor shall be provided with a Building passcard which shall be returned to Landlord upon the later of the receipt of the C of O or completion of Landlord’s or Tenant’s punch list.
                                Tenant’s Contractor must comply with all noise and time regulations of the City of Cambridge for construction including weekend or holiday work.

                              Insurance and Liability. Tenant’s general contractor, engineer, consultants and architect shall provide Landlord with insurance certificates with coverages reasonably satisfactory to
                                Landlord, with all certificates naming Landlord as certificate holder and additional insured and Fairlane Columbia, LLC, 432 Columbia Street Condominium Trust and LPC Commercial Services, Inc. as additional insureds
                                (“Insurance Coverage”). In the event that Tenant chooses to use a construction manager instead of a general contractor, then all subcontractors shall provide Insurance Coverage to Landlord. Landlord shall have no liability
                                for any loss or damage to any of Tenant’s fixtures or property installed or left in the Premises, unless such loss or damage is the result of a willful act or gross negligence of Landlord, Landlord’s Agent or Landlord’s
                                vendors. Tenant shall hold harmless, indemnify and defend Landlord from and against any and all liabilities arising from or relating to the New Lab Tenant Improvements, unless such loss or damage is the result of a willful
                                act or gross negligence of Landlord, Landlord’s Agent or Landlord’s vendors.

                  “If a tenant (or, in each case below, a unit owner) offers any of its employees parking in the Parking Lot, then the tenant has the option of charging such
                    employee market rate for parking, or, alternatively, if the tenant charges any of its employees less than the current monthly market rate for parking, then the tenant will offer such employees an equivalent monthly  payment to support
                    the employee’s commute  by walking, biking. transit or carpool. In the event that an employee chooses to use the equivalent monthly payment for transit, tenants will use best efforts to enroll in the MBTA pass program
                      to provide an employee with the ability to purchase a pass using pre-tax wages. ‘Equivalent monthly payment’ means the remainder of the current monthly market rate for parking less the fee paid for parking  by an employee. For
                    example, if the current monthly market rate is $200 and an employee is being charged $50 per month by the employer, then the equivalent monthly payment equals $150 per month. Any tenant may charge certain  employees  for parking at
                    market rate in the Parking Lot and other employees may be charged at less than the current monthly market rate for parking in the Parking Lot with the tenant providing such employees with the equivalent monthly benefit option.”

                              City of Cambridge Parking and Transportation Demand Management (PTDM) plan (2020 Requirements). If a tenant (or, in each case below. a unit owner) offers any of its employees parking in the Parking Lot, then the tenant
                                has the option of charging such employee market rate for parking. or, alternatively, if the tenant charges any of its employees less than the current monthly market rate for parking, then the tenant will offer such employees
                                an equivalent monthly payment to support the employee’s commute by walking, biking, transit or carpool. In the event that an employee chooses to use the equivalent monthly payment for transit,  tenants will use best
