 THIS LEASE is entered into between Landlord and Tenant as of the Effective Date set forth above. 

ARTICLE 1. LEASE 
  

	 	1.01	Lease. Landlord leases to Tenant and Tenant leases from Landlord the Leased Premises (excluding all Common Areas and all pipes, ducts, conduits, wires, and appurtenant fixtures located therein serving other parts
of the Building) upon all of the terms, covenants and conditions set forth herein. 

  

	 	1.02	Appurtenant Rights. Tenant shall have, as appurtenant to the Leased Premises, rights to use in common (subject to rules and regulations made by Landlord pursuant to Section 4.14): (a) the common
lobbies, corridors, stairways, elevators of the Building serving the Leased Premises in common with others; (b) common walkways providing access to the Building; (c) if the Leased Premises include less than the entire rentable area of any
floor, the common toilets, corridors and elevator lobby on such floor and serving the Leased Premises; and (d) all other General Common Areas from time to time intended for general use by Tenant, other Building tenants, and Landlord.


 ARTICLE 2. TERM; RENT 
  

	 	2.01	Term. The Term of the Lease, in respect of the Existing Subleased Premises (as defined below), shall commence at 12:01 A.M. on the Term Commencement Date set forth in the Basic Lease Information
Sheet. The Term of the Lease, in respect of the Additional Premises and, if applicable, the Expansion Premises (each, as defined below), shall commence at 12:01 A.M. on the respective Delivery Date for each such space as set forth below.
The initial Term for the entire Leased Premises shall end at 11:59 P.M. on the Term Expiration Date set forth in the Basic Lease Information Sheet, unless sooner terminated in accordance with the provisions hereof, or extended as set forth
herein. Tenant’s obligations under this Lease shall commence upon the Term Commencement Date (for the Existing Subleased Premises) and upon the respective Delivery Date (for the Additional Premises and, if applicable, the Expansion
Premises), except as expressly otherwise provided in this Lease (including, without limitation, as to the Rent Commencement Date(s) for the respective portions of the Leased Premises as more particularly set forth in this Lease). 


(a) Existing Subleased Premises. The “Existing Subleased Premises” shall mean the portion of the Leased
Premises outlined as the Existing Subleased Premises on Exhibit A attached hereto. Tenant, as subtenant, currently occupies the Existing Subleased Premises pursuant to a sublease from Massachusetts Financial Services Company (“MFS”).
Landlord shall be deemed to have delivered to Tenant, and Tenant shall be deemed to have accepted, the Existing Subleased Premises in their then “as is” condition on the Term Commencement Date for the Existing Subleased Premises set forth
in the Basic Lease Information Sheet. 
 (b) Additional Premises. The “Additional Premises” shall mean a
portion of the balance of Floor 12 of the Building that is outlined as the Additional Premises on Exhibit A attached hereto. The Additional Premises, together with the Existing Subleased Premises, are currently leased by MFS under a lease
currently scheduled to expire on February 28, 2013, without any right of extension. Landlord shall not extend the term of the MFS’s lease in respect of any 

  
 - 4 - 








 
portion of the Leased Premises beyond the scheduled expiration date set forth above. MFS has advised Landlord that it may vacate the Additional Premises prior to such scheduled expiration date,
in which event the Additional Premises may become available for space preparation work prior to such date. 
 As used
herein, the “Scheduled Delivery Period” for the Additional Premises shall mean the period commencing on December 1, 2012 and ending on April 1, 2013. The “Delivery Date” for the Additional Premises shall mean the date
on which Landlord delivers the Additional Premises to Tenant, free and clear of all occupants and after substantial completion of the work that is required under Section 3.05 below to be performed by Landlord prior to the Delivery Date for the
Additional Premises. Landlord shall use reasonable efforts to so deliver the Additional Premises to Tenant as early as is practicable during the Scheduled Delivery Period (after MFS vacates and surrenders such space and Landlord has substantially
completed the work that it is required to perform prior to the Delivery Date under Section 3.05 below), provided that (i) the Additional Premises shall not be delivered to Tenant prior to the Scheduled Delivery Period, unless Tenant
elects to accept such early delivery of the Additional Premises, and (ii) any delay in such delivery beyond the Scheduled Delivery Period shall not give rise to any claim, damage, or liability of Landlord, except that the Rent Commencement Date
(solely in respect of the Additional Premises) shall be delayed by one day for each day (if any) that the Delivery Date for the Additional Premises is delayed after the last day of the Scheduled Delivery Period (it being agreed, however, that such
delay in the Rent Commencement Date for the Additional Premises shall not derogate from Landlord’s ongoing obligation to continue to use reasonable efforts to deliver the Additional Premises as soon as possible after the end of the Scheduled
Delivery Period). 
 (c) Initial Expansion Right for Balance of Floor 12. Notwithstanding the foregoing, if
Tenant so elects by written notice given to Landlord on or before February 28, 2013, the Leased Premises shall further include the Expansion Premises (the “Initial Expansion Right”), subject to the terms set forth below. The
“Expansion Premises” shall mean the entire balance of Floor 12 of the Building (i.e., the portion of the floor exclusive of the Existing Subleased Premises and the Additional Premises, and subject to the exclusions set forth in
Section 1.01) as shown on Exhibit A attached hereto. Tenant’s notice exercising the Initial Expansion Right must be unconditional and irrevocable in order to be effective. Failure to timely deliver Tenant’s notice exercising the
Initial Expansion Right shall constitute Tenant’s waiver of the Initial Expansion Right. If Tenant timely exercises the Initial Expansion Right in accordance with this Section 2.01(c), (i) the definition of the Leased Premises in the
Basic Lease Information Sheet shall mean the entire Floor 12 of the Building (subject to the exclusions in Section 1.01), (ii) the Leased Premises shall be deemed to include the balance of Floor 12 for all purposes hereunder
(subject to the exclusions in Section 1.01), and (iii) the Net Rentable Area of Leased Premises, the Tenant Work Allowance, the Tenant’s Proportionate Share, and the Letter of Credit (or Security Deposit) shall each be increased as
set forth in the Basic Lease Information Sheet. Tenant’s lease of the Expansion Premises under this Section 2.01(c) shall be on all of the terms and conditions of this Lease that are applicable to the initial Additional Premises, except as
otherwise expressly set forth in this Lease. If Tenant timely exercises the Initial Expansion Right in accordance with this Section 2.01(c), the provisions of this Section 2.01(c) shall be self-operative, without the need for the parties
to execute any further instrument, but upon Landlord’s request the parties shall execute a confirmatory instrument acknowledging the exercise of the Initial Expansion Right and the terms applicable thereto under the provisions of this Lease.


  
 - 5 - 








 As used herein, the “Scheduled Delivery Period” for the Expansion
Premises shall mean the period commencing on December 1, 2012 and ending on April 1, 2013. The “Delivery Date” for the Expansion Premises shall mean the date on which Landlord delivers the Expansion Premises to Tenant, free and
clear of all occupants. Landlord shall use reasonable efforts to so deliver the Expansion Premises to Tenant as early as is practicable during the Scheduled Delivery Period (after MFS vacates and surrenders such space), provided that
(i) the Expansion Premises shall not be delivered to Tenant prior to the Scheduled Delivery Period, unless Tenant elects to accept such early delivery of the Expansion Premises, and (ii) any delay in such delivery beyond the Scheduled
Delivery Period shall not give rise to any claim, damage, or liability of Landlord, except that the Rent Commencement Date (solely in respect of the Expansion Premises) shall be delayed by one day for each day (if any) that the Delivery Date for the
Expansion Premises is delayed after the last day of the Scheduled Delivery Period (it being agreed, however, that such delay in the Rent Commencement Date for the Expansion Premises shall not derogate from Landlord’s ongoing obligation to
continue to use reasonable efforts to deliver the Expansion Premises as soon as possible after the end of the Scheduled Delivery Period). 
  

	 	2.02	Use. Tenant shall not use the Leased Premises for any use or purpose other than the Permitted Use (as defined in Section 10.01), except as permitted by Landlord pursuant to Landlord’s written consent.


  

	 	2.03	Rent. All obligations of Tenant to make payments to Landlord under this Lease shall constitute Rent. Tenant shall pay the Rent at the times and in the manner hereinafter set forth. 


Subject to the rent abatement set forth in the immediately following paragraph, Tenant shall pay the Gross Rent, consisting of Net Rent and
Tenant’s Proportionate Share of Estimated Operating Cost and Estimated Impositions (each as defined in Section 10.01), in twelve (12) equal installments on the first day of each calendar month during each year of the Term and any
extensions thereof. (The calculation of Tenant’s Proportionate Share under Section 10.01 shall be made using the same measurement methodology for the Net Rentable Area of the entire Office Section as was used for determining the Net
Rentable Area of Leased Premises set forth in the Basic Lease Information Sheet.) Such payments shall be made in lawful money of the United States, in advance without demand, and (except as expressly provided herein) without any reduction,
abatement, counterclaim or set off, at the address for Landlord specified on the Basic Lease Information sheet or at such other address as may be designated by Landlord from time to time by written notice provided in accordance with
Section 8.06 below. 
 Notwithstanding the foregoing, (i) Gross Rent in respect of the Existing Subleased Premises shall be abated
for the period commencing on the Term Commencement Date through the date immediately preceding the Rent Commencement Date set forth in the Basic Lease Information Section, (ii) Gross Rent in respect of the Additional Premises shall be abated
for the period commencing on the Delivery Date for the Additional Premises through the date immediately preceding the Rent Commencement Date set forth in the Basic Lease Information (subject to the last sentence of Section 2.01(b) in respect of
a delayed delivery of the Additional Premises), and (iii) Gross Rent in respect of the Expansion Premises shall be 

  
 - 6 - 








 
abated for the period commencing on the Delivery Date for the Expansion Premises through the date immediately preceding the Rent Commencement Date set forth in the Basic Lease Information
(subject to the last sentence of Section 2.01(c) in respect of a delayed delivery of the Expansion Premises); provided, however, that, in the event of an Event of Default, Tenant shall pay to Landlord a fractional portion of the amount
of such abated Gross Rent, in the ratio that (x) the number of full or partial months from the date of default through the originally scheduled Term Expiration Date (without regard to extension under Section 9.01 and not to exceed eighty
four months) bears to (y) eighty four (84) months. Payment of Additional Rent (as defined in Section 10.01), if any, shall commence on the Term Commencement Date for the Subleased Premises and on the applicable Delivery Date for the
Additional Premises and (if applicable) the Expansion Premises. If such rent abatement period expires on a day that is not the last day of a calendar month, the Gross Rent due for the portion of such month following such expiration of the rent
abatement period shall be prorated on a per diem basis and paid on the first day of such month. If the Term terminates on other than the last day of a calendar month, then Gross Rent provided for such partial month shall be equitably prorated on
such date of termination. 
  

	 	2.04	Operating Cost. 

  

	 	(a)	Subject to the exclusions set forth in Section 2.04(c) below, Operating Cost shall mean all expenses and costs of every kind and nature which Landlord shall pay or become obligated to pay because of or in
connection with the management, maintenance, preservation or operation of the Building (determined in accordance with generally accepted accounting principles, consistently applied) including, but not limited to the following: 


 

	 	(1)	Expenses of the operation, maintenance and security of the Building, including compensation in the form of wages, salaries, and other compensation and benefits (including payroll taxes, federal, state and local
unemployment taxes and social security taxes, insurance, welfare and retirement benefits, and related expenses and benefits of all on-site and off-site employees, reasonably pro-rated to reflect services provided for the Building and other
building(s)). 

  

	 	(2)	Cost for Landlord’s office and management office operation for the Building, including the actual cost (or, if not paid, the imputed fair market rent) of any space occupied by entities providing management or
building services for the Building, which shall be reasonably allocated between the Building and any other buildings served by the personnel occupying such space; 


 

	 	(3)	All tools, supplies, materials and equipment used in the operation and maintenance of the Building, including rental fees for the same, if such items are not purchased and amortized pursuant to (10) below;


  

	 	(4)	Utilities, including electricity, water, sewer, gas, communication, heating, lighting, air conditioning and ventilating, for the entire Building (subject to the exclusions set forth below for separately reimbursable
tenant charges); 

  

	 	(5)	 All maintenance, janitorial and service agreements and costs for the Building, including, without limitation, alarm service, landscaping,




  
 - 7 - 









	 	
window cleaning, escalator and elevator maintenance, rubbish and snow removal, pest control, equipment maintenance or servicing or maintenance or cleaning for sidewalks, Building exterior, roof
and service areas; 

  

	 	(6)	A management fee in connection with the operation of the Building; provided, however, that Tenant’s share of such Operating Cost shall be separately calculated and equal three percent (3%) of all Rent under
this Lease, excluding such fee, and that such share shall be in lieu of Tenant’s Proportionate Share of the management fee for the entire Building; 

  

	 	(7)	Legal and accounting services for the Building, including the costs of audits by certified public accountants, but excluding legal costs incurred in proceedings against any specific tenant or in connection with the
development, financing, and leasing of the Building; 

  

	 	(8)	All insurance premiums and costs applicable to the Building and Landlord’s personal property used in connection therewith, including but not limited to, the premiums and cost of fire, casualty and liability
coverage and rental abatement and business interruption insurance and unreimbursable costs incurred by Landlord that are subject to an insurance deductible; 

  

	 	(9)	Repairs, replacements and general maintenance (except for repairs covered by insurance or reimbursable by Tenant or other third parties, and alterations attributable solely to tenants of the Building other than Tenant);


  

	 	(10)	Amortization (together with reasonable actual or imputed financing charges) of capital improvements made to the Building that (i) are reasonably designed to improve the quality or operating efficiency of the
Building (by an amount reasonably projected by Landlord to equal or exceed the amortized costs of such improvements with respect to capital expenditures for operating efficiency), (ii) may be required by governmental authorities (other than a
failure of the Building to comply with any law in effect and interpreted to apply to the Property as of the date hereof) or any insurer of the Building, or (iii) constitute equipment of a capital nature contemplated in (3) above (such as,
for example, snow blowers, vacuums and sweepers), which in Landlord’s reasonable judgment, is ultimately less costly to purchase than to rent. 

  

	 	(b)	 Notwithstanding any other provision herein to the contrary, in the event that the Building is not fully occupied during any year of the Term, an
adjustment shall be made in computing Operating Cost for such year so that the components of Operating Cost that vary with occupancy shall be extrapolated to equal the amount of such variable Operating Cost that would have been incurred if the
Building had been fully occupied during such year; provided, however, that in no event shall Landlord collect in total, from Tenant and all other tenants of the Building, an amount greater than one hundred percent (100%) of any item of the
actual Operating Cost during any year of the Term. For a simplified illustration (with rounded hypothetical numbers), if the costs of providing standard office tenant cleaning services had been $500,000 for 500,000 rentable square feet of occupied
office tenant space during an entire 



  
 - 8 - 









	 	
year, the Office Section of the Building had contained 700,000 rentable square feet, and the incremental cost of providing such cleaning services for the balance of the Office Section, if
occupied, would have been at the same per square foot rate, then for purposes of computing Operating Cost for such year the amount of such variable office tenant cleaning services included in Operating Cost would be extrapolated to $700,000.


  

	 	(c)	Notwithstanding the foregoing, Operating Cost shall not include (i) costs associated with the operation of the parking garage forming part of the Building (including the elevators serving the garage), or with the
development, financing, or leasing (including the procurement of tenants) of the Building (including, without limitation, attorneys’ fees in connection therewith); (ii) costs for tenant electricity (of the type specified in
Section 3.01(b)) or for extra services (of the type specified in Section 3.02) that are separately billable to and payable by other tenants leasing space in the Office Section of the Building, (iii) those costs and expenses which are
properly attributable to or separately payable by the tenants in the Commercial Section of the Building; (iv) that portion of the costs and expenses relating to the loading dock facilities and the General Common Areas which is paid by the
tenants in the Commercial Section of the Building; (v) compensation paid to any executives or principals of Landlord above the grade of senior property manager, except that such costs shall be included in Operating Cost to the extent such
person actually performs services that are attributable to actual Building operations or that would have been performed by an outside consultant and included in Operating Cost hereunder; (vi) Impositions and other taxes excluded from
Impositions as set forth in Section 2.05 below; (vii) depreciation, and any rent paid on any ground or underlying lease of the Land; (viii) debt service payments, other costs of financing or refinancing of any Mortgage, or costs
incurred in connection with any other financing, sale, or syndication of the Building or any interest therein; (ix) advertising costs, brokerage commissions, attorneys’ fees, and other expenses incurred in negotiating leases (or
assignments, subleases or amendments thereof) with tenants of the Building or preparing such tenants’ spaces for occupancy; (x) costs of capital items, except as expressly included above in clause (a)(10) in Operating Cost;
(xi) costs for which Landlord is reimbursed under insurance policies or otherwise by third parties (including other tenants for separately reimbursable charges, such as overtime HVAC or special services); (xii) the incremental additional
costs of any work or service performed for any other tenant to a materially greater extent or in a materially more favorable manner than that furnished to Tenant; (xiii) damages, penalties, fines, or interest which Landlord is obligated to pay
by reason of failure by Landlord to comply with applicable law or its lease obligations; (xiv) charitable, civic and political contributions or similar donations, and (xv) costs of services provided to other tenants and not to Tenant.


  

	 	2.05	 Impositions. “Impositions” shall mean all real estate or personal property taxes, possessory interest taxes, or similar charges,
business or license taxes or fees, service payments in lieu of such taxes or fees, annual or periodic license or use fees, excises, assessments, levies, fees or charges, general and special, ordinary and extraordinary, unforeseen as well as
foreseen, of any kind (including fees “in-lieu” of any such tax or assessment) which are assessed, levied, charged, or imposed by any public authority upon the Land, the Building, its operations or the Rent (or any portion or component
thereof) including, in the year paid, all fees and costs incurred by Landlord in seeking to obtain an abatement or reduction of, or a 



  
 - 9 - 









	 	
limit on any increase, in any taxes, regardless of whether any abatement, reduction or limitation is obtained, but excluding (i) inheritance, estate, franchise, capital stock, or gift taxes
imposed upon or assessed against the Building, or any part thereof or interest therein, (ii) taxes computed upon the basis of the net income derived from the Building by Landlord or the owner of any interest therein, (iii) that portion of
the items enumerated in this Section which is properly attributable to or separately payable by the tenants in the Commercial Section of the Building; (iv) any of the enumerated items payable with respect to the parking garage forming part of
the Building (including the elevators serving such garage) or (v) any penalties, fines, or interest which Landlord is obligated to pay by reason of failure by Landlord to timely pay Impositions (except to the extent attributable to
Tenant’s failure to comply with its obligations hereunder). Landlord shall refund or credit to Tenant its Proportionate Share of any abatement actually received by Landlord (net of fees and costs not previously included in Tenant’s share
of Impositions) for Impositions for any year included in the Term for which Tenant previously paid such Impositions, provided that Tenant is not in default under the Lease continuing beyond any applicable notice and cure period. 


 

	 	2.06	Computation Of Operating Cost and Impositions Adjustment. Landlord shall from time to time give Tenant written notice of the applicable Estimated Operating Cost and Estimated Impositions and any adjustments
thereto. Landlord shall, after the end of each calendar year of the Term, give written notice to Tenant containing or accompanied by a statement of the Operating Cost and Impositions during such calendar year, and also accompanied by a computation
of the Operating Cost Adjustment and the Impositions Adjustment, if any. Landlord shall use reasonable efforts to provide such statement within one hundred twenty (120) days after the end of each calendar year for which an adjustment is due,
but Landlord’s failure to give such statement within such period shall not release either party from the obligation to make the adjustment provided for in Section 2.07. Such statement shall be deemed accepted if not disputed, within six
months after Tenant’s receipt thereof, by written notice to Landlord stating the items that Tenant disputes. If Tenant so requests and is not in default under the Lease continuing beyond any applicable notice and cure period, Landlord shall
(a) provide a copy of its audited statement for the calendar year just ended (or, if an audited statement is not available, the statement shall be certified by an officer or representative of Landlord) and (b) provide or permit Tenant (or
its designated certified public accountant from a reputable national or regional accounting firm reasonably acceptable to Landlord) to review reasonable backup information concerning specific line items in such annual statement that Tenant in good
faith disputes, which request may be made within one hundred twenty days after receipt of the year-end statement and not more than once annually; provided that as a condition thereof Landlord may require Tenant (and, if applicable, its designated
accountant) to enter into a confidentiality agreement with respect to any such information. Tenant agrees that it shall not engage any person or entity on a contingency fee basis in connection with any such review. If Tenant engages a designated
accountant as aforesaid, Tenant shall provide Landlord with a copy of its report within sixty (60) days after the commencement of its review hereunder, which shall identify all items that Tenant in good faith disputes. Tenant shall be deemed to
have accepted the year-end statement with respect to all items that are not timely identified in such report as being in dispute. 

  

	 	2.07	 Adjustment For Variation Between Estimated And Actual. If the Operating Cost and/or the Impositions for any calendar year exceed the Estimated
Operating Cost and/or the Estimated Impositions, Tenant shall pay to Landlord Tenant’s 



  
 - 10 - 









	 	
Proportionate Share of such excess within thirty (30) days after presentation of Landlord’s statement pursuant to Section 2.06. If the Operating Cost and/or Impositions for any
calendar year is less than the Estimated Operating Cost and/or the Estimated Impositions, then Landlord shall pay to Tenant Tenant’s Proportionate Share of such difference within thirty (30) days after the Operating Cost Adjustment and/or
the Impositions Adjustment is finally determined. Should the Term commence or terminate at any time other than the first day of a calendar year, Tenant’s Proportionate Share of the Operating Cost Adjustment and/or Impositions Adjustment shall
be prorated for the exact number of calendar days for which Tenant is obligated to pay Gross Rent, and in the case of the expiration or any early termination of this Lease, the provisions of this Section 2.07 shall survive such expiration or
termination. 

 ARTICLE 3. LANDLORD’S COVENANTS 

 

	 	3.01	Basic Services. 

  

	 	(a)	Landlord shall furnish or cause to be furnished the following Basic Services to Tenant during Business Hours (unless otherwise stated herein) during Tenant’s occupancy of the Leased Premises: 


 

	 	(i)	Hot and cold water used at all times by the building standard cooling, drinking and sanitation systems, and for maintenance and janitorial services. 


 

	 	(ii)	Central heat and air conditioning in season, at such temperatures and in such amounts as are from time to time furnished to tenants in Comparable Buildings in Downtown Boston, or as may be permitted or controlled by
applicable laws, ordinances, rules and regulations. 

  

	 	(iii)	Maintenance, repairs, structural and exterior maintenance (including exterior glass and glazing) as set forth in Section 3.06, painting and electric lighting service for all Common Areas, Building Common Areas and
General Common Areas in the manner and to the extent customarily provided by landlords in Comparable Buildings in Downtown Boston. 

  

	 	(iv)	Janitorial service after Business Hours on Business Days in accordance with the cleaning specifications attached as Exhibit E (or such other specifications as Landlord may from time to time adopt that are
consistent with prevailing standards for comparable buildings in downtown Boston). 

  

	 	(v)	Electricity at all times for (1) building standard light fixtures, (2) desktop personal computers, typewriters, telephones, fax machines, printers, copying machines, and other equipment of similar low
electrical consumption in the Leased Premises, and (3) building standard air handling units and related HVAC equipment for the floor on which the Leased Premises are located (it being agreed that Tenant’s consumption for the items under
clause (2) shall not exceed two (2) watts per square foot of Usable Area per month at 120 volts). 


  
 - 11 - 









	 	(vi)	Initial lamps, bulbs, starters and ballasts for building standard fixtures used within the Leased Premises. 

  

	 	(vii)	A system of access control for the Building during hours when the Building is not generally open to the public and during such other hours as Landlord may from time to time designate. During such hours, Landlord may
employ a system of monitoring and limiting access to the office floors in the Building based on reasonable systems of identification. Landlord reserves the right from time to time to modify components of such system, to change the number of lobby
attendants, or to institute, modify, supplement, or discontinue any access control procedures or equipment for the Building or the Project, whether during or after business hours. Landlord does not warrant or guarantee the effectiveness of any such
system or procedures. Tenant expressly disclaims any such warranty, guarantee, or undertaking by Landlord with respect thereto and acknowledges that access control procedures from time to time in effect are solely for the convenience of tenants
generally and are not intended to secure the Leased Premises or guarantee the physical safety of tenants’ employees or invitees in or about the Leased Premises or the Project. Tenant shall be responsible for securing the Leased Premises,
subject to Landlord’s approval under Section 4.07 of Tenant’s installation of access card readers or other security equipment for the Leased Premises. Subject to the foregoing, access to the Leased Premises shall be available on a
24-hours-a-day, seven-days-a-week basis, subject to temporary interruptions for annual power testing (as to which Landlord shall use reasonable efforts to advise building tenants in advance in a manner consistent with the operation of Comparable
Buildings in Downtown Boston) and emergencies and the terms and conditions of the Lease. 

  

	 	(viii)	Public elevator service serving the floors on which the Leased Premises are situated, including a freight elevator. (At least one passenger elevator shall be available after regular Business Hours, subject to clause
(vii) above.) 

  

	 	(b)	Tenant shall pay to Landlord, as Additional Rent, the cost of electricity provided under Section 3.01(a)(v). Such charges shall be based on the usage shown on the check meter installed for the floor on which the
Leased Premises are located, with the cost equitably apportioned among tenants on the floor. Landlord shall make periodic meter readings and make appropriate adjustments among the tenants on the floor based on the actual amount of electricity
consumed and then applicable utility company rates. If Tenant’s electricity usage exceeds the standard level set forth in Section 3.01(a)(v), charges for such additional usage shall be payable under Section 3.02. 


 

	 	(c)	 To the maximum extent permitted by law, Landlord shall not be liable for injuries to persons or damage to property, nor shall Landlord be deemed to
have evicted Tenant, nor shall there be any abatement of Rent, nor shall Tenant be relieved from performance of any covenant on its part to be performed hereunder or have any right to terminate the Lease by reason of




  
 - 12 - 









	 	
any (i) deficiency in the provision of Landlord services under this Article 3, (ii) breakdown of equipment or machinery utilized in supplying services, or (iii) curtailment or
cessation of services or any other failure by Landlord to perform any obligation under the Lease, except as expressly provided in this Lease. Landlord shall use reasonable diligence to make such repairs as may be required to machinery or equipment
within the Building to provide restoration of services and, where the cessation or interruption of service has occurred due to circumstances or conditions beyond Building boundaries, to cause the same to be restored, by diligent application or
request to the provider thereof. In no event shall any mortgagee referred to in Section 4.11 be or become liable for any default of Landlord under this Section 3.01(c). 


 

	 	(d)	Notwithstanding the foregoing, in the case of fire or other casualty, Tenant shall have the abatement and termination rights set forth in Section 5.07. With respect to matters not covered by Section 5.07, if
Tenant is prevented, on account of Landlord’s failure to perform any of its service obligations under this Lease where the failure is caused by matters within Landlord’s reasonable control, from using all or a substantial portion (meaning
at least twenty five percent) of the Leased Premises for more than five (5) Business Days following notice to Landlord, then from and after the end of such five-(5)-Business-Day period until the Leased Premises (or such portion) is rendered
usable, Net Rent and other charges allocable to the Leased Premises, or a just and proportionate part thereof, shall be abated until such time as the service is restored. If such failure renders the Leased Premises untenantable for more than five
(5) months following notice to Landlord (and any mortgagee of which Landlord has given Tenant notice), then Tenant may, by thirty (30) days’ prior notice to Landlord (and such mortgagee), terminate this Lease; provided, however, that
such termination shall be effective only if the Leased Premises are not made tenantable within such thirty-day period. 

  

	 	3.02	Extra Services. Landlord shall provide to Tenant at Tenant’s sole cost and expense at standard Building charges in effect from time to time (and subject to the limitations hereinafter set forth) the
following: 

  

	 	(a)	Heating, ventilation, air conditioning or extra service (i) during hours other than Business Hours, and (ii) on days other than Business Days, said heating, ventilation and air conditioning or extra service to
be furnished solely upon the prior written request of Tenant given with such advance notice as Landlord may reasonably require; 

  

	 	(b)	Additional air conditioning and ventilating capacity or chilled and/or condenser water required by reason of any electrical, data processing or other equipment or facilities or services required to support the same, to
the extent in excess of that which would be required for Building Standard Improvements; 

  

	 	(c)	Repair and maintenance which is the obligation of Tenant hereunder, if so requested by Tenant; 

  

	 	(d)	Additional cleaning and janitorial services to the extent that the quality, quantity, or scope of such services exceeds the building-standard level of services provided to tenants of the Office Section generally.



  
 - 13 - 









	 	(e)	Additional electricity above the standards specified in the parenthetical in Section 3.01(a)(v), in which case Tenant shall pay to Landlord, as Additional Rent, the costs of such additional electricity usage (at
then applicable utility company rates) based either on a separate meter or meters measuring such electrical consumption or on a reasonable determination by Landlord’s engineer as to the level of electrical consumption in the Leased Premises,
which determination shall be conclusive and binding on the parties. Tenant shall be responsible for the costs of installing such meters and all electrical equipment reasonably required for such additional electricity usage. All work necessary for
such installation shall be done in accordance with the requirements of Section 4.02 (regarding Tenant Improvements). 

  

	 	(f)	Maintenance and replacement of initial lamps, bulbs, starters and ballasts; 

  

	 	(g)	Any Basic Service in amounts reasonably determined by Landlord to exceed the amounts required to be provided under Section 3.01(a). 


The cost chargeable to Tenant for all extra services shall constitute Additional Rent. Building standard charges are designed to recover, from
Tenant and other tenants using such services, the costs reasonably estimated by Landlord to provide such services. If the same extra service is provided to Tenant and other tenants (such as regularly scheduled, above-standard cleaning services),
Tenant’s share shall equal the total cost thereof multiplied by the quotient of the Net Rentable Area of the Leased Premises over the total Net Rentable Areas of all areas to which such extra service is provided. Landlord may include the
estimated monthly amount of any regularly provided extra service in the Estimated Operating Cost for the Leased Premises, subject to adjustment under Section 2.06 and 2.07. Unless otherwise provided herein, all payments of Additional Rent shall
be due with the payment of Gross Rent next due at least thirty (30) days after billing. 
  

	 	3.03	Window Covering. Building standard window coverings have previously been installed in the Leased Premises. Tenant shall not place or maintain any window covering, blinds or drapes (other than those supplied by
Landlord) on any exterior window without Landlord’s prior written approval which Landlord shall have the right to grant or withhold in its absolute and sole discretion. Tenant shall comply with Landlord’s Building-standard requirements for
lighting all portions of the Leased Premises that are visible from the exterior. Tenant acknowledges that breach of this Section 3.03 will directly and adversely affect the exterior appearance of the Building. 


 

	 	3.04	 Graphics And Signage. Landlord shall install, at Landlord’s expense, the initial listing for Tenant in the Building directory in the
ground floor lobby and the initial Building standard directional signage for Tenant in the elevator lobby on any multi-tenant floor on which the Leased Premises are located; thereafter, any changes to such signage (not to exceed two additional
listings, which may be used for assignees or subtenants of Tenant at the Leased Premises) shall be at Tenant’s expense. Tenant shall install, at Tenant’s expense, identification of Tenant’s name and suite numerals at the main door (or
its adjacent window panel) at the entrance to the Leased Premises, with the size, materials, colors, and graphics approved in advance by Landlord, such approval not to be unreasonably withheld or delayed. Any other signs, notices and graphics of
every kind or character, located on such entrance door (or adjacent window panel) shall be subject to Landlord’s prior written approval, which Landlord shall not unreasonably withhold or delay.




  
 - 14 - 









	 	
Except as set forth above, Tenant shall not be permitted to maintain any signage in the public corridors, the Common Areas, the Building Common Areas, or the General Common Areas, on the exterior
of the Leased Premises, or in a location otherwise visible from the exterior of the Leased Premises. 

  

	 	3.05	Initial Tenant Improvements. Landlord at its expense shall construct (a) the common area corridors on the floor in building standard condition (the “Corridor Work”) and (b) a new demising wall
separating such corridor from the Additional Premises (studs and corridor-side sheetrock only to the point of turnover to Tenant for the commencement of Tenant’s Construction Work under Exhibit B hereto) (the “Demising Wall
Work”). Within the common area corridor and other non-Tenant portion of the floor resulting from such demising work, Landlord is responsible for reconfiguration of life safety systems, HVAC, electrical wiring, painting, and finishing, and
Tenant is responsible for reconfiguration of such elements within its Leased Premises (subject to reimbursement from the Tenant Work Allowance). The parties will reasonably cooperate with each other to coordinate the Corridor Work (such that such
work is substantially completed by the date Tenant’s Construction Work in the Additional Premises is substantially completed) and the Demising Wall Work by Landlord (prior to the Delivery Date). Notwithstanding the foregoing, Landlord may, at
its election, cause the Corridor Work and/or the Demising Wall Work to be performed by the contractor engaged by Tenant, pursuant to a separate contract with Landlord, in which event such work shall be performed concurrently with Tenant’s
Construction Work. If Landlord’s contractor is performing the Demising Wall Work, Landlord shall substantially complete the Demising Wall Work on or before the Delivery Date for the Additional Premises. Notwithstanding the foregoing, if Tenant
exercises the Initial Expansion Right for the balance of Floor 12 under Section 2.01(c) above, then Landlord shall not be obligated to perform any Corridor Work or Demising Wall Work in connection with the delivery of the Additional Premises
and the Expansion Premises under Section 2.01. 

 All other preparation work for the Additional Premises, together with
all refurbishment work for the Existing Subleased Premises, shall be performed by Tenant in accordance with Exhibit B attached hereto. 
  

	 	3.06	Repair Obligation. Subject to the terms and conditions of this Lease, Landlord shall maintain in good operating repair (which may be effected by Landlord’s replacement of worn-out items) and condition,
reasonable wear and tear excepted (so long as such elements continue to operate) and damage by fire or casualty excepted, (i) the structural portions of the Building, (ii) the exterior wall of the Building, including glass and glazing,
(iii) the roof, (iv) mechanical, electrical, plumbing and life safety systems, serving to the perimeter of the Leased Premises, and (v) Common Areas, Building Common Areas and General Common Areas. Upon not less than five
(5) Business Days’ prior notice to Tenant (except in the case of an emergency), Landlord shall have the right, but not the obligation, to undertake maintenance or repair work which Tenant is required to perform pursuant to
Section 4.04 and which Tenant fails or refuses to perform in a timely and efficient manner; and all reasonable costs incurred by Landlord in performing any such repair for the account of Tenant shall be repaid by Tenant to Landlord upon demand,
together with an amount equal to ten percent (10%) of such costs, to reimburse Landlord for its administration and managerial effort. 

  

	 	3.07	 Quiet Enjoyment. So long as Tenant pays the Rent and performs all of Tenant’s covenants and agreements contained in this Lease within
applicable notice and 



  
 - 15 - 









	 	
cure periods, Tenant shall peacefully have, hold and enjoy the Leased Premises, subject to the terms of this Lease and other matters to which this Lease is or may (pursuant to Section 4.11)
become subject and subordinate, including without limitation (i) that certain Amended and Restated Sale and Construction Agreement by and among the City of Boston, the Boston Redevelopment Authority, New England Mutual Life Insurance Company
and Gerald D. Hines Interests, Inc., dated April 15, 1986, recorded with the Suffolk Registry of Deeds in Book 12515, Page 78, the covenants therein relating to the land being incorporated by reference herein, as required pursuant to the terms
of Section 1304 thereof, and (ii) that certain Construction, Operation and Reciprocal Easement Agreement (“REA”) by and between Landlord and New England Mutual Life Insurance Company, dated May 29, 1986, recorded with the
Suffolk Registry of Deeds in Book 2524, Page 236 and as amended on April 13, 1989, each as hereafter amended from time to time. This covenant is in lieu of any other so-called covenant of quiet enjoyment, either express or implied. This
covenant and the other covenants of Landlord contained in this Lease shall be binding upon Landlord and its successors and assigns only with respect to breaches occurring during its and their respective ownerships of Landlord’s interest
hereunder. 

 ARTICLE 4. TENANT’S COVENANTS 

 

	 	4.01	Obligations Of Tenant To Furnish Floor Plans. Pursuant to Exhibit B, Tenant shall deliver to Landlord for its approval the plans and specifications for Tenant’s initial improvements to the Additional
Premises and any other improvements or other refurbishments to the balance of the Leased Premises. 

  

	 	4.02	Construction Of Tenant Improvements. Landlord and Tenant shall comply with the obligations set forth in Exhibit B with respect to all Tenant Improvements to be installed and constructed by such party.


  

	 	4.03	Taxes On Personal Property. In addition to, and wholly apart from its obligation to pay Tenant’s Proportionate Share of Operating Costs and Impositions, Tenant shall be responsible for and shall pay, prior
to delinquency, taxes or governmental service fees, possessory interest taxes, fees or charges in lieu of any such taxes, capital levies, or other charges imposed upon, levied with respect to or assessed against its personal property, or the value
of its Tenant Improvements, or its interests pursuant to this Lease. To the extent that any such taxes are not separately assessed and billed to Tenant and were billed to Landlord, Tenant shall pay the amount thereof as invoiced to Tenant by
Landlord together with reasonable documentation evidencing such charges. 

  

	 	4.04	 Repairs By Tenant. Tenant shall maintain and repair the Leased Premises, keep the same in such good order, repair and condition as the same are
in on the Term Commencement Date or thereafter may be put in compliance with the Lease and, upon expiration of the Term, surrender the same to Landlord in the condition required under Section 4.07, reasonable wear and tear, damage by fire or
other casualty, loss from condemnation, and maintenance and repairs that are Landlord’s obligation excepted. Tenant’s obligation shall include, without limitation, the obligation within the Leased Premises to maintain and repair all walls
(except the exterior surface or structural portion of the Building or any building systems), floors, ceilings, windows (except for windows located on the exterior of the Building), doors and fixtures and to repair all damage caused by Tenant or its
Invitees to the Leased Premises or anywhere in the Building. At the 



  
 - 16 - 









	 	
request of Tenant, Landlord shall perform the maintenance and repair work required under this Section 4.04 at Tenant’s sole cost and expense and as an extra service to be rendered
pursuant to Section 3.02. Any work of repair and maintenance performed by or for the account of Tenant by persons other than Landlord shall be performed by contractors approved by Landlord in accordance with Section 4.07 and in accordance
with procedures that Landlord shall from time to time establish. Nothing herein contained, however, shall be deemed to impose upon Tenant the obligation to perform maintenance and repair work required by reason of the negligence or wrongful acts of
Landlord or its agents or employees. 

  

	 	4.05	Waste. Tenant shall not commit or allow any waste or damage (except as set forth in Section 5.07) to be committed in any portion of the Leased Premises. 


 

	 	4.06	Assignment Or Sublease. 

  

	 	(a)	In the event Tenant intends to assign this Lease or sublet the Leased Premises or any part thereof to a person or entity which controls, is controlled by or is under common control with Tenant, or an entity into or with
which Tenant is merged or consolidated or to which substantially all of Tenant’s assets are transferred (hereinafter, “Affiliate”), then Tenant shall give Landlord written notice of such intent. As used herein, “control”
shall mean ownership of more than 50% of the shares or beneficial interests of the entity in question, together with the power to control and manage the affairs thereof either directly or by election of directors and/or officers. Landlord’s
consent shall not be required for a sublease to an Affiliate, provided that Tenant shall provide Landlord with reasonable evidence of such transaction and the sublease otherwise complies with this Lease. Landlord shall approve an assignment to an
Affiliate, provided that the Affiliate is of sound financial condition (taking into account the remaining obligations under the Lease), as reasonably determined by Landlord. Furthermore, Landlord’s prior consent shall not be required for an
office-sharing arrangement (without construction of internal demising walls) that Tenant may from time to time enter into with one or more reputable business vendors providing services to Tenant at the Leased Premises (each, a “Tenant Related
Party”), provided that (i) the same do not cover more than 2,000 square feet of Net Rentable Area in the aggregate, (ii) Tenant provides Landlord with reasonable evidence of such transaction and insurance certificates consistent with
the requirements of this Lease, and (iii) the transaction otherwise complies with this Lease. 

  

	 	(b)	 Tenant shall have the right to seek an assignment (or a subletting of more than 2,000 square feet of Net Rentable Area of the Leased Premises) to a
person or entity other than an Affiliate, only upon the expiration of one (1) year from the Term Commencement Date. In the event Tenant intends to assign this Lease or sublet the Leased Premises or any part thereof to a person or entity other
than an Affiliate, the Tenant shall give Landlord written notice of such intent. Tenant shall provide Landlord with (i) the name of the proposed assignee or subtenant, (ii) such information as to the financial responsibility and standing
of such assignee or subtenant as Landlord shall reasonably require, (iii) the proposed transfer instrument or, if such an instrument has not then been negotiated, a summary of the material terms and conditions upon which the proposed assignment
or subletting is to be made (including economic terms as negotiated in a letter of intent or, if not then negotiated, as proposed by Tenant), and (iv) any additional information or




  
 - 17 - 









	 	
documents reasonably requested by Landlord within five (5) Business Days after receipt of Tenant’s initial submission (in which event Tenant shall provide such additional information or
documents to Landlord within ten (10) Business Days). Tenant shall not assign this Lease, nor sublet the Leased Premises or any portion thereof to any person or entity who is then a tenant in the Project (unless Landlord, after Tenant’s
request, acknowledges that no suitable space is available therein); any party with whom Landlord or any affiliate of Landlord is then negotiating with respect to space in the Project for a term reasonably comparable to the term proposed by Tenant
(as evidenced by Landlord’s showing space to said party and by exchanging proposals with said party). Landlord shall designate, within seven (7) days after Tenant’s request specifying the term proposed by Tenant, the parties then
meeting such parameters, provided that, if so requested by Landlord, Tenant shall maintain the confidentiality of any such non-public information); or any entity owned by, owning, or affiliated with, directly or indirectly, any tenant or other party
as set forth in this sentence. 

  

	 	(c)	 Except for any sublease that is for less than two (2) years and, when combined with all prior sublease(s), is for less than 2,000 square feet of
Rentable Floor Area in the aggregate, Landlord shall, by the date five (5) Business Days following the receipt of the additional information or documents required under (b)(iv) above (or, if later, by the date fifteen (15) days after the
initial submission of the information required under (b) above) notify Tenant in writing whether Landlord elects to terminate this Lease as to the space in the Leased Premises so affected as of the date specified by Tenant for the commencement
of the proposed sublease or assignment and for the period specified by Tenant (that is, such recapture shall be for remainder of the Term if Tenant proposes a sublease for all or substantially all of the remainder of the Lease Term, but otherwise
for such shorter period as may be specified by Tenant in its notice hereunder). If Landlord makes such election, Tenant will be relieved of all further obligations hereunder as to such space and such period as is so specified in Tenant’s
notice, and (if the termination applies only to a portion of the Leased Premises) Landlord shall at its expense construct the demising wall and corridor modifications necessary to effect such termination. If Landlord should fail to notify Tenant in
writing of such election to terminate within said period, Landlord shall be deemed to have elected not to terminate. If Landlord does not so terminate (or if Landlord has no such termination right under the first sentence of this subparagraph), then
by the date fifteen (15) days following receipt of the exact copy of the proposed transfer instrument (or, if later, by the date five (5) Business Days after receipt of the information required under (b) above), Landlord shall grant
or deny consent for Tenant to assign this Lease or sublet such space, such consent not to be unreasonably withheld or conditioned so long as (w) the proposed transfer instrument complies with this Lease (Landlord’s approval of which shall
not be unreasonably withheld if the same complies with this Lease), (x) the use of the Leased Premises by such proposed assignee or sublessee would be a Permitted Use, (y) the character and business reputation of the proposed assignee or
sublessee is consistent with the character of the Building as a first-class office building, and (z) the proposed assignee or sublessee is of sound financial condition as reasonably determined by Landlord (which determination shall take into
account the continuing liability of Tenant hereunder and the remaining obligations under the Lease). Any denial by Landlord of such consent shall be in writing and specify the reasons for denial. In no event shall a failure by Landlord to




  
 - 18 - 









	 	
approve a proposed subtenant or assignee cause a termination of this Lease. If Landlord terminates this Lease as to a portion of the Leased Premises as provided above, upon request of either
party Landlord and Tenant shall enter into a modification of this Lease that reflects such termination as to the space and term in question. 

  

	 	(d)	Any rent or other consideration realized by Tenant in connection with any such sublease or assignment in excess of the Rent payable hereunder, after deduction of the reasonable cost of Tenant Improvements installed
solely for sublease purposes for which Tenant has paid and reasonable legal fees, commissions and other reasonable subletting and assignment costs, shall be paid as follows: fifty percent (50%) of the excess shall be retained by Tenant and
fifty percent (50%) of the excess shall be paid to Landlord. 

  

	 	(e)	In marketing all or part of the Leased Premises hereunder, Tenant shall not publicly advertise (by means of on-line broker listings, flyers, or otherwise) rental terms for the space that are less than the fair market
rent rate for comparable space in the Project. The foregoing sentence shall not, however, prevent Tenant from listing the space with “terms available upon request” or from privately offering, negotiating, or entering into a transaction (in
accordance with this Section 4.07) with a particular party on terms that are lower than the fair market rent rate for comparable space in the Project. 

  

	 	(f)	 In the case of each assignment or sublease: (i) Tenant and the assignee or subtenant, as the case may be, shall execute an assignment or sublease
which shall include terms that do not materially differ from those theretofore disclosed to Landlord; (ii) within three (3) Business Days after the execution thereof, an executed copy of the assignment or sublease shall be delivered to
Landlord; (iii) the terms and provisions of any such assignment or sublease shall specifically prohibit the assignment of the interest of the sublessee or assignee, or the sub-subletting of all or any portion of the Leased Premises covered by
the sublease without the prior written consent of the Landlord, which consent may be withheld in Landlord’s absolute discretion, unless otherwise expressly agreed by Landlord at the time of such consent; (iv) no assignment or subletting
shall affect the continuing primary liability of Tenant (which, following assignment or sublease, shall be joint and several with the assignee or subtenant, as the case may be; however, Landlord shall have no obligation to name any such assignee or
sublessee, in connection with enforcing any of Landlord’s right against Tenant hereunder); (v) no consent by Landlord to any of the foregoing in the specific instance shall operate as a waiver in any subsequent instance; (vi) no
assignment or subletting shall be permitted to the extent the same causes Tenant to be in default under any Subordination, Non-Disturbance and Attornment Agreement to which it is a party; (vii) no assignment or subletting shall permit the
assignee, sublessee or any other person or entity having an interest in the possession, use, occupancy or utilization of the Leased Premises, to receive or to pay rental or payment on account of the use, occupancy or utilization of the Leased
Premises based in whole or in part on the net income or profits derived by any person or entity from any property leased, used, occupied or utilized (other than an amount based on a fixed percentage or percentages of receipts of sales); and
(viii) no assignment shall be binding upon Landlord, unless Tenant shall deliver to Landlord an instrument in recordable form which contains a covenant of assumption by the assignee and in form and in substance reasonably satisfactory to
Landlord running to 



  
 - 19 - 









	 	
Landlord and all persons claiming by, through and under Landlord, but the failure or refusal of the assignee to execute such instrument of assumption shall not release or discharge the assignee
from its primary liability as Tenant hereunder. If Tenant enters into any sublease or assignment, Landlord may from time to time require that such subtenant or assignee agree directly with Landlord to be liable, jointly and severally with Tenant,
solely to the extent of the obligation undertaken by or attributable to such subtenant or assignee, for the performance of Tenant’s agreements under this Lease (including payment of rent and other charges under the sublease or assignment), and
every sublease or assignment shall so provide. In the event of a default by Tenant under the Lease, Landlord may collect rent and other charges from the subtenant or assignee and apply the net amount collected to the rent and other charges due under
the Lease, but no such collection shall be deemed a waiver of the provisions of Section 4.06, or the acceptance of the subtenant or assignee, as a tenant, or a release of Tenant from its direct and primary liability for the performance of all
of Tenant’s obligations under the Lease. 

  

	 	(g)	No assignment or subletting by Tenant shall relieve Tenant of any obligation under this Lease. Any assignment or subletting without obtaining Landlord’s prior consent or approval as required under this
Section 4.06 shall be void. 

  

	 	(h)	If Tenant has failed to execute an assignment or sublease within six (6) months following the giving by Tenant of written notice of its intent to effect an assignment or subletting under Section 4.06(b) above,
Tenant shall again be obligated to notify Landlord of any intent to assign this Lease or sublet all or any portion of the Leased Premises, and Landlord shall again have the right to approve any proposed assignment or sublease or to terminate this
Lease under Section 4.06(c). 

  

	 	4.07	 Alterations And Surrender. Tenant shall not make or allow to be made any alterations or physical additions in or to the Leased Premises without
obtaining the prior written consent of Landlord, which consent shall not be unreasonably withheld, conditioned, or delayed with respect to proposed alterations and additions which (i) comply with all applicable laws, ordinances, rules and
regulations, (ii) are compatible with the Building and its mechanical, electrical, HVAC and life safety systems, and do not excessively burden the capacity of such systems; (iii) will not interfere with the use and occupancy of any other
portion of the Building; (iv) will not affect the structural integrity of the Building; and (v) will satisfy the standards and comply with the procedures and requirements required for Tenant Improvements, as set forth in Exhibit B.
(Notwithstanding the foregoing, Tenant shall not be required to obtain Landlord’s prior approval of plans for cosmetic alterations or standard equipment installations in the Leased Premises (such as painting, carpeting, or installations of
built-in workstations, furniture, cabinets, or decorations), provided that such alterations (i) comply with the preceding sentence and do not include or affect any mechanical, electrical, or plumbing work or life safety or other Building
systems or any structural elements of the Building, (ii) the cost of such alterations does not exceed $25,000 in the aggregate and (iii) such alterations shall otherwise be performed by Tenant, with reasonable prior notice to Landlord, in
accordance with the terms and provisions of this Lease including, without limitation, this Section 4.07.) Specifically, but without limiting the generality of the foregoing, Landlord’s right of consent shall encompass plans and
specifications for proposed alterations or additions, construction means and methods, the identity of any contractor or subcontractor to be employed on the work of alterations or additions, and the time for performance




  
 - 20 - 









	 	
of such work. Tenant shall supply to Landlord any documents and information reasonably requested by Landlord in connection with its consent hereunder. (Any comments or disapproval by Landlord
shall provide reasonable detail as to the objection.) Landlord’s approval of the plans, specifications and working drawings for Tenant’s alterations shall create no responsibility or liability on the part of Landlord for their
completeness, design sufficiency, or compliance with all laws, rules and regulations of governmental agencies or authorities. All alterations and additions permitted hereunder shall be made and performed by Tenant without cost or expense to
Landlord. Tenant shall take such steps as Landlord or its mortgagee may deem reasonably necessary to avoid the filing, perfection or enforcement of any lien for labor or materials against the Land or the Building by reason of work performed by or on
behalf of Tenant. 

 All Tenant Improvements under Section 3.05, and all alterations, physical additions or improvements
made to the Leased Premises by Tenant under this Section 4.07, shall become the property of Landlord upon the termination of this Lease and shall be surrendered to Landlord upon the termination of this Lease by lapse of time or otherwise;
provided, however, that this clause shall not apply to business equipment, fixtures, or related installations or any other moveable equipment, furniture or personal property, and shall not apply to any Tenant Improvements, alterations, additions or
improvements specified by Tenant to Landlord and approved by Landlord in writing prior to their installation or to any special installations, plumbing, fixtures or other additions or improvements that would require unusual expense to re-adapt the
Leased Premises for general office purposes and are so specified by Landlord for removal (which items Landlord, if so requested by Tenant, shall specify at the time of Landlord’s approval of the construction documents for such work), all of
which shall be removed by Tenant, at Tenant’s expense, prior to the expiration of the Term (or, if the parties so agree in lieu of such removal, Tenant shall pay to Landlord an amount equal to the estimated cost of removing such items).
Landlord specifically reserves the right to require Tenant to remove at the end of the Term any private bath and shower facilities in the Leased Premises and, at Tenant’s request at the time of approval of the plans therefor, shall indicate
which elements of such improvements are to be removed. Tenant shall be responsible for leaving the Leased Premises clean and tenantable (and the obligations of Tenant provided for in this paragraph shall survive any expiration or termination of this
Lease). Title to all alterations, physical additions or improvements and Tenant Improvements not removed by Tenant pursuant to this paragraph on or prior to the termination of the Term shall automatically be conveyed and transferred by Tenant to
Landlord upon such expiration or termination, and shall be deemed abandoned by Tenant and shall thereupon become the property of Landlord. Tenant shall execute such documentation confirming and ratifying such conveyance and transfer as Landlord
shall reasonably require. Tenant shall repair at its sole cost and expense all damage caused to the Leased Premises or the Building by removal of Tenant’s moveable equipment, or graphics, or furniture and such other alterations and additions as
Tenant shall be allowed or required to remove from the Leased Premises by Landlord. If Tenant fails to perform any of its obligations under this paragraph prior to the expiration or earlier termination of the Term, then (without limiting any other
remedies for such default) at Landlord’s election at any time thereafter Landlord may perform such work for Tenant’s account and at Tenant’s expense, and upon demand Tenant shall reimburse Landlord for all costs thereof (including the
administrative fee set forth in Section 3.06) as an extra service hereunder, together with holdover rent under Section 8.02 for the period required to perform such work if and to the extent Tenant’s failure to perform such work delays
the space preparation work for the next tenant of all or part of the Leased Premises. 

  
 - 21 - 









	 	4.08	Compliance With Laws And Insurance Standards. Tenant shall not occupy for use, or permit any portion of the Leased Premises to be occupied or used, for any business or purpose which is disreputable or creates a
fire hazard, or permit anything to be done which would in any way increase the rate of insurance coverage on the Building and/or its contents. If Tenant does or permits anything to be done which shall increase the cost of any insurance policy
required to be carried hereunder, then Tenant shall reimburse Landlord, within thirty (30) days after receipt of an invoice, for any such additional premiums. Landlord shall deliver to Tenant a written statement setting forth the amount of any
such insurance cost increase and showing in reasonable detail the manner in which it has been computed and determined chargeable to Tenant. Tenant shall comply with all laws, ordinances, orders, rules and regulations (state, federal, municipal or
promulgated by other agencies or bodies having or claiming jurisdiction) now in force or which may hereafter be in force related to the use, condition or occupancy of the Leased Premises (excluding any matters that are part of Landlord’s
maintenance or repair obligations hereunder) or the conduct of Tenant’s business therein, including but not limited to, any requirements concerning hiring of employees and provisions for the disabled, and Tenant shall keep the Leased Premises
equipped with all safety appliances required by any law or ordinance or other regulation of any public authority because of any use made by Tenant of the Leased Premises, and shall procure all licenses and permits so required because of such use,
and, if required by Landlord, do any work so required because of such use, it being understood that the foregoing provisions shall not be construed to broaden in any way the Permitted Use. Nothing done by Tenant in its use or occupancy of the Leased
Premises shall create, require or cause imposition of any requirement by any public authority for structural or other upgrading of or improvement to the Building. Tenant shall not allow to be brought into the Leased Premises or the Building any
biologically or chemically active or other hazardous substances or materials, except for ordinary office and cleaning supplies used in the ordinary course of Tenant’s business and use of the Leased Premises in compliance with the Lease and
applicable law. If a lender or governmental agency shall require monitoring or testing to ascertain whether there has been a release of such materials or substances, then the reasonable costs thereof shall be reimbursed by Tenant to Landlord if the
requirement is based upon the reasonable belief that the release was caused by Tenant or any person acting under or through Tenant. 

  

	 	4.09	 Entry For Repairs And Leasing. After reasonable notice (which may be made, in accordance with customary administrative procedures, by telephone
or electronic means, and shall not be required by Tenant to be made more than three (3) days in advance, except in emergencies when no such notice shall be required), Landlord, its agents and representatives, shall have the right to enter the
Leased Premises to inspect the same, to exercise such rights as may be permitted hereunder, to make repairs or alterations to the Building or other tenant spaces therein, to deal with emergencies, to post such notices as may be permitted or required
by law to prevent the perfection of liens against Landlord’s interest in the Building, or to exhibit the Leased Premises to prospective tenants (during the last twelve (12) months of the Term), purchasers, encumbrancers or others, or for
any other purpose consistent with the operation of comparable buildings in downtown Boston as Landlord may deem reasonably necessary or desirable; provided, however, that Landlord shall exercise all such entry rights in a manner consistent




  
 - 22 - 









	 	
with comparable buildings in downtown Boston and use reasonable efforts not to unreasonably interfere with Tenant’s business operations. Except as set forth in Section 3.01(d), Tenant
shall not be entitled to any abatement of Rent by reason of the exercise of any such right of entry. 

  

	 	4.10	No Nuisance. Tenant shall conduct its business and control its agents, employees, invitees and visitors in such manner as not to create any nuisance, or interfere with, annoy or disturb any other tenant or
Landlord in its operation of the Building. 

  

	 	4.11	 Subordination. Landlord represents that there is currently no Mortgage (or ground lease) on the Building or the Land. This Lease and the rights
of Tenant hereunder shall be subject and subordinate to the lien of any Mortgage hereafter placed on the Building or the Land, and to any and all advances made thereunder, interest thereon or costs incurred in connection therewith. Without the
consent of Tenant, the holder of any such Mortgage shall have the right to elect to be subject and subordinate to this Lease, such subordination to be effective upon such terms and conditions as such holder may direct which are not inconsistent with
the provisions hereof. Notwithstanding any foreclosure or sale under any such Mortgage (or deed in lieu thereof), this Lease (pursuant to a subordination, non-disturbance and attornment agreement as provided below or otherwise at the option of the
holder of the Mortgage, the purchaser at a foreclosure sale or grantee of deed in lieu of foreclosure) shall remain in full force and effect and Tenant shall attorn to the holder or the purchaser at any such sale or foreclosure or the grantee of any
such deed. So long as there is no Event of Default, Tenant’s agreement to subordinate the Lease to a future Mortgage as set forth above shall be conditioned on Landlord causing the holder of such Mortgage to execute and deliver a subordination,
non-disturbance and attornment agreement on such mortgagee’s customary form, which shall provide that, so long as this Lease is in full force and effect and there exists no Event of Default hereunder, Tenant’s rights under this Lease shall
not be disturbed by reason of such subordination or by reason of foreclosure of such Mortgage, or exercise of the statutory power of sale, or receipt of deed in lieu of foreclosure. Upon any attornment as set forth above, this Lease shall continue
in full force and effect as a direct lease between such mortgagee, purchaser or grantee, as a successor landlord, and Tenant, upon all the terms, conditions and covenants set forth herein, except that such mortgagee, purchaser or grantee (unless
formerly the Landlord under this Lease) shall not be (a) bound by any payment of Rent for more than one month in advance; (b) bound by any amendment or modification of this Lease made without the consent of the holder of the Mortgage;
(c) liable in any way to Tenant for any prior act or omission, neglect or default on the part of Landlord under this Lease, (d) obligated to perform any work or improvements to be done by Landlord in the Leased Premises; or
(e) subject to any counterclaim or set off which theretofore accrued to Tenant against Landlord. Tenant further agrees that this Lease shall be subject and subordinate to any amendment hereafter made to the recorded instruments referenced in
Section 3.07, and to any other instrument by which Landlord may subject the Building and the Land to easements in connection with the development, redevelopment, alteration, improvement, operation, maintenance or repair thereof, provided the
same do not interfere (in a manner inconsistent with the operation of Comparable Buildings in Downtown Boston) with Tenant’s use of the Leased Premises for the Permitted Uses or unreasonably interfere with Tenant’s rights and benefits
expressly set forth in the Lease. The provisions of this Section 4.11 shall be self-operative, with no further instrument of subordination being required. Within ten (10) days after Landlord’s request,




  
 - 23 - 









	 	
Landlord and Tenant shall execute, acknowledge and deliver any documents reasonably appropriate to confirm such provisions. No owner of the Leased Premises shall be liable under this Lease except
for breaches of Landlord’s obligations occurring while such person is the owner of the Leased Premises. 

  

	 	4.12	Estoppel Certificate. At Landlord’s request, Tenant shall execute (within fifteen (15) days after Tenant receives any such request) estoppel certificates on a form specified by Landlord, addressed to
(i) any mortgagee or prospective mortgagee of Landlord or (ii) any purchaser or prospective purchaser of all or any portion of, or interest in, the Building, certifying that the Lease is in full force and effect against Tenant without
amendment except as provided therein, the date through which Gross Rent has been paid, that neither Tenant nor, to its knowledge, Landlord is in default under the Lease and to its knowledge Tenant has no claims, defenses, or offsets against the
enforcement of the Lease in accordance with its terms, the amount of any security deposit or letter of credit held under the Lease, and such other matters concerning the Lease as such mortgagee(s) or purchaser(s) may reasonably require; provided,
however, that in no event shall any such estoppel certificate require an amendment of the provisions hereof or otherwise affect or abridge Tenant’s rights hereunder. At Tenant’s request, Landlord shall execute (within fifteen
(15) days after Landlord receives any such request) an estoppel certificate to a proposed subtenant, assignee, or lender of Tenant on a form reasonably acceptable to Landlord, certifying as to such facts (if true) regarding the Lease as are
customarily addressed in such estoppel certificates; provided, however, that in no event shall any such estoppel certificate require an amendment of the provisions hereof or otherwise affect or abridge Landlord’s rights hereunder.


  

	 	4.13	Tenant’s Remedies. Tenant shall look solely to Landlord’s interest in the Building for recovery of any judgment from Landlord. Landlord, its agents, its employees, and (if Landlord is a partnership or
joint venture) its partners, whether general or limited, or (if Landlord is a corporation), its directors, officers, and shareholders, or (if Landlord is a limited liability company), its members, manager, and officers, or (if Landlord is a trust)
its trustees and beneficiaries, shall never be personally liable for any such judgment. Any lien obtained to enforce any such judgment and levy of execution thereon shall be subject and subordinate to any Mortgage. Landlord shall not be deemed to be
in default of any obligation hereunder unless Tenant has given Landlord written notice of the alleged default specifying the applicable provision of this Lease and the same remains uncured after thirty days (or, except in cases of imminent risk to
person or property, such longer period as may be reasonably necessary to cure the same). In no event shall Landlord be liable for consequential or indirect damages. In addition to the other remedies provided in this Lease, Tenant shall be entitled
to the restraint by injunction of the violation or attempted or threatened violation of any of the covenants, conditions or provisions of this Lease by Landlord or to a decree compelling specific performance of any such covenants, conditions or
provisions. No termination remedy that is not expressly set forth in this Lease for any breach or failure by Landlord to perform any obligation under this Lease shall be implied or applicable as a matter of law. This Lease shall be construed as
though Landlord’s and Tenant’s covenants contained herein are independent and not dependent, and Tenant hereby waives the benefit of any statute or judicial law to the contrary. 


 

	 	4.14	Rules and Regulations. Tenant shall comply with the rules and regulations for the Building attached as Exhibit C and such amendments thereto as Landlord may adopt from time to time with prior notice to Tenant.
Landlord’s rules and regulations shall not be enforced or enacted against Tenant in a discriminatory manner. 


  
 - 24 - 









	 	4.15	Personal Property At Tenant’s Risk. All of the furnishings, fixtures, equipment, effects and property of every kind, nature, and description of Tenant and of all persons claiming by, through and under Tenant
which, during the continuance of this Lease or any occupancy of the Leased Premises by Tenant or anyone claiming under Tenant, may be on the Leased Premises or elsewhere in the Building, shall be at the sole risk and hazard of Tenant to the maximum
extend permitted by law, and if the whole or any part thereof shall be destroyed or damaged by fire, water or otherwise, by the leakage or bursting of water pipes, steam pipes, or other pipes, or by theft or from any other cause, no part of said
loss or damage is to be charged to or be borne by Landlord, except Landlord shall in no event be held harmless or exonerated for any liability to Tenant or to any other person, for any injury, loss, damage or liability to the extent such indemnity,
hold harmless or exoneration is prohibited by law. 

  

	 	4.16	Payment Of Landlord’s Expenses. Tenant shall pay, as Additional Rent, all reasonable out-of-pocket costs, counsel and other fees incurred by Landlord in connection with all requests by Tenant for consent or
approval under this Lease (excluding approvals of plans for Tenant’s Construction Work), and the enforcement by Landlord of any obligation of Tenant under this Lease. 


 

	 	4.17	Letter of Credit/Security Deposit. On the execution of this Lease, Tenant shall deliver to Landlord either (a) a letter of credit or (b) a cash security deposit securing the performance of the
obligations of Tenant hereunder, in the amount specified therefor in the Basic Lease Information Sheet. Any such letter of credit shall comply with the requirements of Exhibit D attached hereto (as more particularly defined therein, the “Letter
of Credit”), which is incorporated herein by reference. Any cash security deposit from time to time held hereunder may be mingled with other funds of Landlord and no fiduciary relationship shall be created with respect to such deposit, nor
shall Landlord be liable to pay Tenant interest thereon. If Tenant shall fail to perform any of its obligations under this Lease after the expiration of any applicable notice and cure period (or fail to perform any of its obligations under the Lease
and transmittal of a default notice or running of a cure period is barred or tolled by applicable law), Landlord may, but shall not be obliged to, draw on the Letter of Credit and/or apply any cash security deposit to the extent necessary to cure
such failure to pay, and Tenant shall reinstate such cash security deposit or Letter of Credit to the original amount thereof upon demand (it being understood that such reinstatement obligation shall take into account both the then undrawn amount of
the Letter of Credit and any unapplied cash security deposit then held by Landlord). Within thirty (30) days after the expiration or sooner termination of the Term the cash security deposit or Letter of Credit, to the extent not applied, shall
be returned to the Tenant, without interest. 

  

	 	4.18	 Tenant’s Financial Condition. Within ten (10) Business Days after request from Landlord from time to time (but not more often than
once in any twelve-(12)-month period), Tenant shall deliver to Landlord (or, at Tenant’s election, directly to the party requesting the same, provided it is a party described in the next sentence) Tenant’s financial statements (audited, if
available) for the most recent fiscal year for which such statements are available and, for the most recent four quarters not covered by such statements, quarterly financial statements certified by Tenant’s chief financial officer. Such
financial statements shall be requested only 



  
 - 25 - 









	 	
as reasonably necessary to satisfy the needs of Landlord’s current and prospective mortgagees, lenders, purchasers, and investors. All financial statements shall be confidential and shall be
used only for the purposes set forth in this Lease. If requested by Tenant, any such non-public financial information shall be provided pursuant to a commercially reasonable confidentiality agreement, in form reasonably acceptable to the parties.


  

	 	4.19	Energy Conservation. Tenant agrees to cooperate with Landlord and to abide by all Building regulations which Landlord may, from time to time, reasonably prescribe for the proper functioning and protection of the
heating, air-conditioning, lighting, and electrical systems and in order to maximize the effect thereof and to conserve heat, air-conditioning, and electricity. Notwithstanding anything to the contrary in this Lease, Landlord may institute such
policies, programs and measures as may be in Landlord’s reasonable judgment necessary, required or expedient for the conservation or preservation of energy or energy services, or as may be necessary to comply with applicable codes, rules,
regulations or standards. 

  

	 	4.20.	Discharge of Mechanic’s and Materialman’s Liens. Tenant agrees within ten (10) Business Days after notice of filing to discharge of record by payment, filing of the necessary bond, order of a court
of competent jurisdiction, or other means acceptable to Landlord, any mechanic’s, materialman’s, design professional or other lien against the Leased Premises and/or Landlord’s or Tenant’s interest therein (or any other portion
of the Project) when such lien arises out of work performed or claimed to have been performed in or on the Leased Premises by Tenant or any party acting under or through Tenant, which liens may arise out of any payment due for, or purported to be
due for, any labor, services, materials, supplies or equipment alleged to have been furnished to or for the Tenant in, upon or about the Leased Premises. In the event Tenant contests any such lien, Tenant shall either (i) deposit with Landlord
an amount equal to the claims made by such lien, together with interest thereon as it may from time to time become due, as security for the payment and discharge thereof prior to execution or (ii) deliver to Landlord a bond of a recognized
surety authorized to write surety bonds in Massachusetts assuring the payment and removal of such lien, together with any interest or penalty thereon, and naming Landlord as a co-obligee. Any judgment or other process issued in such a contest shall
be paid and discharged before execution thereof. If Tenant fails to keep this covenant, in addition to all other remedies available to Landlord under this Lease, Landlord may, at its option, purchase a surety bond at twice the amount of the lien,
securing such lien, and Tenant agrees to pay to Landlord, as Additional Rent, the cost thereof, plus (i) an administrative charge of ten percent (10%) of such cost to compensate Landlord for its expenses and overhead, and
(ii) Landlord’s reasonable attorneys’ fees and damages. 

 ARTICLE 5. CASUALTY, EMINENT DOMAIN 

 

	 	5.01	 Landlord’s Casualty Insurance. Landlord shall maintain, or cause to be maintained, a policy or policies of all risk or special form
insurance (or its then comparable equivalent) insuring the Building against loss or damage by fire or other insurable hazards and contingencies, with coverages and amounts required from time to time by Landlord’s first mortgagee or, if there is
no such requirement, in then commercially reasonable types of coverage and amounts as determined from time to time by Landlord, in the exercise of its good faith judgment, to be necessary or appropriate for the Building as a first-class mixed-use




  
 - 26 - 









	 	
project in the Back Bay district of Boston; provided, that Landlord shall not be obligated to insure any furniture, equipment, machinery, goods or supplies which Tenant may keep or maintain in
the Leased Premises or any Tenant Improvements or other Alterations installed by Tenant. If the annual premiums charged Landlord for such casualty insurance exceed the standard premium rates because the nature of Tenant’s operations in the
Leased Premises results in extra-hazardous exposure, then Tenant shall, upon receipt of appropriate premium invoices, reimburse Landlord for such increases in premium as Additional Rent. 


 

	 	5.02	Landlord’s Liability Insurance. Landlord shall maintain, or cause to be maintained, a policy or policies of commercial general liability insurance, with coverages and amounts required from time to time by
Landlord’s first mortgagee or, if there is no such requirement, in then commercially reasonable types of coverage and amounts as determined from time to time by Landlord, in the exercise of its good faith judgment, to be necessary or
appropriate for the Building as a first-class mixed-use project in the Back Bay district of Boston. 

  

	 	5.03	Tenant’s Insurance. Tenant shall maintain the following coverages in the following amounts: 

  

	 	(a)	Commercial General Liability insurance covering claims of bodily injury, personal injury, and property damage arising out of Tenant’s operations and contractual liabilities, including coverage formerly known as
broad form, on an occurrence basis, with minimum primary limits of $1,000,000 each occurrence and $2,000,000 annual aggregate and a minimum excess/umbrella limit of $5,000,000. 


 

	 	(b)	Property insurance covering (i) all office furniture, business and trade fixtures, office equipment, free-standing cabinet work, movable partitions, merchandise and all other items of Tenant’s property in the
Leased Premises installed by, for, or at the expense of Tenant (“Tenant’s Property”), and (ii) any Tenant Improvements (“Tenant-Insured Improvements”), together with business interruption insurance covering periods of
not less than one (1) year in the following amounts: (i) for the first twelve (12) months of the Term an amount equal to 1 1⁄2 times the Gross
Rent ; and (ii) for each succeeding twelve-(12)-month period, in amounts not less than the Gross Rent and Tenant’s other operating expenses for the preceding twelve-(12)-month period, provided that Tenant may, at its option, elect not to
maintain business interruption coverage, provided that if Tenant does not maintain such coverage, any loss or damage to Tenant which would have been covered by such business interruption coverage shall be deemed, for the purposes of this Lease, to
be covered by insurance. Such insurance shall be written on a special cause of loss form (or its then comparable equivalent) for physical loss or damage, for the full replacement cost value (subject to reasonable deductible amounts) without
deduction for depreciation of the covered items and in amounts that meet any co-insurance clauses of the policies of insurance, and shall include coverage for damage or other loss caused by fire or other peril, including vandalism and malicious
mischief, theft, water damage of any type, including sprinkler leakage, bursting or stoppage of pipes, and explosion, and providing business interruption coverage for a period of one year. 


 

	 	(c)	 Worker’s Compensation and Employer’s Liability or other similar insurance to the extent required by Law. If alcoholic beverages are sold,
used, delivered 



  
 - 27 - 









	 	
or stored on, in or from the Leased Premises, and such alcoholic beverages shall only be sold, used, delivered or stored if Tenant’s Permitted Use expressly so allows, Tenant shall maintain
throughout the Term at its expense, liquor liability insurance or dram shop liability insurance (as applicable) (“Dram Shop Insurance”) with combined single limits of not less than $2,000,000 per occurrence covering any claims relating to
the manufacture, storage, sale, use or giving away of any alcoholic or other intoxicating liquor or beverage, which claims could be asserted against Landlord, Tenant or the Leased Premises. 


 

	 	(d)	The minimum limits of insurance required to be carried by Tenant shall not limit Tenant’s liability. Such insurance shall (i) be issued by an insurance company that has an A.M. Best rating of not less than
A-VIII; (ii) be in form and content consistent with the requirements of this Lease and reasonably acceptable to Landlord; (iii) may be maintained as part of a blanket policy insuring Tenant and its affiliates at other locations, and
(iv) provide that the insurer shall endeavor to provide to Landlord thirty (30) days’ prior notice of any modification or cancellation, except that ten (10) days’ prior notice may be given in the case of nonpayment of
premiums. Tenant’s Commercial General Liability Insurance shall (a) name Landlord, Landlord’s managing agent, and any other party designated by Landlord (“Additional Insured Parties”) as additional insureds; and (b) be
primary insurance as to all claims thereunder and provide that any insurance carried by Landlord is excess and non-contributing with Tenant’s insurance. Tenant shall be responsible for repairing or restoring the Leased Premises as provided in
Section 5.07 and shall designate Landlord as a loss payee with respect to Tenant’s property insurance on any Tenant-Insured Improvements. Tenant shall deliver to Landlord, on or before the Term Commencement Date and at least fifteen
(15) days before the expiration dates thereof, certificates from Tenant’s insurance company on the forms currently designated “ACORD 28” (Evidence of Commercial Property Insurance) and “ACORD 25-S” (Certificate of
Liability Insurance) or the equivalent. Attached to the ACORD 25-S (or equivalent) there shall be an endorsement naming the Additional Insured Parties as additional insureds which shall be binding on Tenant’s insurance company and shall
expressly require the insurance company to endeavor to provide Landlord and each Additional Insured Party at least thirty (30) days’ prior notice of modification or cancellation, except that ten (10) days’ prior notice may be
given in the case of nonpayment of premiums. Upon Landlord’s request, Tenant shall deliver to Landlord, in lieu of such certificates, copies of the policies of insurance required to be carried under Section 5.03(a) showing that the
Additional Insured Parties are named as additional insureds. 

  

	 	(e)	Tenant shall maintain such increased amounts of the insurance required to be carried by Tenant under this Section 5.03, and such other types and amounts of insurance covering the Leased Premises and Tenant’s
operations therein, as may be reasonably requested by Landlord, but not in excess of the amounts and types of insurance then being required by landlords of buildings comparable to and in the vicinity of the Building. In the event that Tenant fails
to timely provide evidence of insurance required to be provided by Tenant hereunder and such failure continues for five (5) business days after Landlord’s written notice to Tenant, Landlord shall be authorized (but not required) to procure
such coverage in the amounts stated with all costs thereof to be chargeable to Tenant as Additional Rent, and payable by Tenant upon receipt of written invoice thereof.

	 	5.04	Indemnity And Exoneration. Except to the extent such indemnity or exoneration is prohibited by law, 

  

	 	(a)	Landlord shall not be liable to Tenant for injury to any person or any loss or damage to any property or any inconvenience caused by (i) theft, burglary or acts of unauthorized persons in on about the Building,
(ii) any act of Force Majeure or (iii) any repair or alteration of any part of the Building or failure to make any such repair; 

  

	 	(b)	Except to the extent of Landlord’s negligence or willful misconduct, Tenant shall indemnify Landlord and hold Landlord harmless of and from any and all loss, cost, damage, injury or expense arising out of or
related to claims of injury to or death of persons or damage to property occurring in or resulting from the use or occupancy of the Leased Premises or activities of Tenant in or about the Leased Premises or, to the extent of Tenant’s negligence
or willful misconduct, elsewhere in or about the Building, such indemnity to include, without limitation, the obligation to provide all costs of defense against any such claims; and 


 

	 	(c)	Tenant shall hold and save Landlord harmless and indemnify Landlord of and from any and all loss, cost, damage, injury or expense arising out of or in any way related to any breach by Tenant of its obligations under
this Lease or any claims for payment for work or labor performed, materials or supplies furnished to or at the request of Tenant or in connection with performance of any work done for the account of Tenant in the Leased Premises or the Building,
such indemnity to include, without limitation, the obligation to provide all costs of defense against any such claim. 

  

	 	5.05	Waiver Of Subrogation Rights. Anything in this Lease to the contrary notwithstanding, Landlord and Tenant each waive all rights of recovery, claim, action or cause of action against the other, its agents
(including partners, both general and limited), officers, directors, shareholders, members trustees, beneficiaries, or employees, for any loss or damage that may occur to the Leased Premises, or any improvements thereto, to the Building or to any
personal property of such party therein, by reason of fire, the elements, or any other cause which is insured against or is required to be insured against by either party under this Lease, regardless of cause or origin, including negligence of the
other party hereto, its agents, officers or employees; and each party covenants that no insurer shall hold any right of subrogation against such other party. Each of Landlord and Tenant shall advise insurers of the foregoing and such waiver shall be
a part of each policy maintained by Landlord and Tenant, as applicable, which applies to the Leased Premises, any part of the Building or Landlord’s or Tenant’s use and occupancy of any part thereof; provided that this waiver shall be null
and void if such waiver is not generally obtainable from insurance companies in the Commonwealth of Massachusetts, and provided further that all costs associated with obtaining insurer consent shall be borne by the party benefited by such waiver.



  
 - 29 - 









	 	5.06	Condemnation And Loss or Damage. 

  

	 	(a)	If the Leased Premises or any substantial portion thereof (meaning at least twenty-five percent thereof) or any portion of the Building shall be taken or condemned for any public purpose to such an extent as to render
the Leased Premises or such portion untenantable, this Lease shall, at the option of either party (provided such option shall be exercised by the giving of notice by the exercising party to the other party within sixty (60) days from the date
the exercising party has been notified in writing of such taking or condemnation) forthwith cease and terminate as of the date of the taking. All proceeds from any taking or condemnation of the Leased Premises shall belong to and be paid to Landlord
and Tenant hereby assigns to Landlord its interest in said proceeds subject to the rights of any holder of any Mortgage; provided, however, that Landlord shall cooperate with Tenant if Tenant seeks, in a separate proceeding, to recover, at its cost
and expense, compensation for its moving expenses, personal property, and loss of business, provided that in no event shall any such recovery by Tenant have the effect of diminishing or delaying the award payable to Landlord on account of any taking
or condemnation. 

  

	 	(b)	In the event of a taking of all or any portion of the Leased Premises not exceeding thirty days, there shall be no abatement of Rent and Tenant shall remain fully obligated for performance of all of the covenants and
obligations on its part to be performed pursuant to the terms of this Lease and shall be entitled to any award for the use of such space during such temporary taking. For any taking exceeding thirty days, Gross Rent shall be equitably abated in
proportion to the nature and extent of the taking, and for any temporary taking exceeding six (6) months the termination rights under (a) above shall apply. All proceeds awarded or paid with respect thereto shall belong to Landlord.


  

	 	5.07	Damage Due to Fire And Casualty. In the event of a fire or other casualty in the Leased Premises, Tenant shall immediately give notice thereof to Landlord. In the event of a fire or other casualty in the Leased
Premises, the following provisions shall then apply whether or not Tenant has given notice to Landlord: 

  

	 	(a)	If the damage is limited solely to the Leased Premises and Landlord determines that the Leased Premises can be made tenantable with substantially all damage repaired within six (6) months from the date such work
begins, then, subject to any limitation contained in any Mortgage, Landlord shall be obligated to rebuild the same and shall proceed diligently to do so; provided, however, that Landlord shall have no obligation to repair or restore the Leased
Premises or Tenant Improvements except to the extent that Landlord realizes insurance proceeds, if any, sufficient for such purposes and for all other restoration and repair purposes and to the extent such proceeds are not applied on account of the
indebtedness secured by any Mortgage. 

  

	 	(b)	 If portions of the Building outside the boundaries of the Leased Premises are damaged or destroyed (whether or not the Leased Premises are also
damaged or destroyed) and Landlord determines that the Leased Premises and the Building can both be made tenantable with substantially all damage repaired within six (6) months from the date work begins, and provided that Landlord determines
that such repair and restoration is economically feasible, then subject to any limitation contained in any Mortgage, Landlord shall be 



  
 - 30 - 









	 	
obligated to do so; provided, however, that Landlord shall have no obligation to repair or restore the Leased Premises or Tenant Improvements except to the extent that Landlord realizes insurance
proceeds, if any, allocable thereto and sufficient for such purpose and for all other restoration and repair purposes. 

  

	 	(c)	If neither subsection 5.07(a) nor 5.07(b) above applies, because Landlord has determined that either the Leased Premises or the Building, or both, cannot be made tenantable within six (6) months from the date work
begins (or if the Leased Premises or the Building will not be repaired due to inadequacy of insurance proceeds), Landlord shall notify Tenant within sixty (60) days after the date of damage or destruction and either Tenant or Landlord may
terminate this Lease within thirty (30) days after the date of such notice; provided, however, that if the Leased Premises are not damaged Landlord shall not terminate the Lease unless it terminates all similarly situated leases in the
Building; and provided further that Landlord or its mortgagee shall have the right to elect to reconstruct the Building and the Leased Premises, in which event Landlord or its mortgagee shall so notify Tenant within said sixty (60) day period
and Tenant shall thereupon have no right to terminate this Lease, except as set forth in the next sentence. If the restoration under subsection 5.07(a), (b) or (c) does not render the Leased Premises tenantable (or if Landlord
determines that the Leased Premises will not be rendered tenantable) within nine (9) months from the date of casualty (as reasonably extended for any delay by Tenant, or as reasonably extended for other Force Majeure event(s), but not in excess
of three (3) months in the aggregate for such other Force Majeure event(s)), then Tenant may terminate the Lease within thirty (30) days thereafter if the restoration is not then substantially completed. In addition, in the event the
Leased Premises are rendered untenantable due to fire or other casualty during the last year of the Term and the estimated restoration period (as reasonably determined by Landlord’s architect or engineer) exceeds one half of the remaining Term,
then either party may terminate the Lease on at least thirty (30) days prior notice to the other if the restoration is not then substantially complete. 

  

	 	(d)	During any period when the Leased Premises or any portion thereof are rendered untenantable by damage or destruction, Gross Rent shall abate proportionately until such time as the Leased Premises are made tenantable and
no portion of the Rent so abated shall be subject to subsequent recapture; provided, however, that the duration of said Rent abatement period shall not exceed one (1) year from the date the Leased Premises are rendered untenantable by such
damage or destruction, except as set forth in the next sentence. If the Leased Premises are not rendered tenantable prior to the expiration of such one-year abatement period and Landlord does not agree to extend such abatement period until the
Leased Premises are rendered tenantable, then Tenant shall have the further right to terminate the Lease by notice given within thirty days after such one-year period, which termination notice shall be effective as of the end of such one-year
abatement period. 

  

	 	(e)	The proceeds from any insurance paid by reason of damage to or destruction of the Building or any part thereof, the Building Standard Improvements or any other element, component or property insured by Landlord shall
belong to and be paid to Landlord, subject to the rights of the holder of any Mortgage, and Tenant hereby assigns to Landlord any interest in said proceeds. 


  
 - 31 - 









	 	(f)	Notwithstanding any provisions contained in this Section 5.07 to the contrary in no event shall any fire or other casualty give Tenant the right to require or demand that Landlord repair or restore any part of the
Building (other than the Leased Premises or access thereto, and then only to the extent required elsewhere in this Section 5.07). 


ARTICLE 6. DEFAULT 
  

	 	6.01	Events of Default. The occurrence of any of the following shall constitute an “Event of Default” on the part of the Tenant: 


 

	 	(a)	Nonpayment of Rent. Failure to pay any payment of Rent (or any installment or portion thereof) upon the date when payment is due, such failure continuing for a period of five (5) Business Days after written notice
of such failure; provided, however, that Landlord shall not be required to provide such notice more than twice during any twelve-month period of the Term with respect to non-payment of any installment of Gross Rent or any portion thereof, the third
such non-payment constituting default without requirement of notice; 

  

	 	(b)	Other Obligations. Failure to perform any obligation, agreement or covenant under this Lease other than those matters specified in Section 6.01(a), such failure continuing for thirty (30) days after written
notice of such failure (or, except in cases of imminent risk to person or property, such longer period as is reasonably necessary to remedy such default, provided that Tenant shall within such thirty (30)-day period have commenced such remedy and
thereafter Tenant shall continuously and diligently pursue such remedy until such default is cured), provided, however, that the cure period for any failure to perform any restoration obligations under Section 4.07 shall be five
(5) Business Days; 

  

	 	(c)	Abandonment. Abandonment of the Leased Premises or any part thereof during the Term. Tenant shall be deemed to have abandoned the Leased Premises if the Leased Premises remain substantially vacant or unoccupied for a
period of ninety (90) days. Notwithstanding the foregoing, for purposes of this clause (c), Tenant shall not be deemed to have abandoned the Leased Premises provided Tenant continues to pay all Rent due and payable under this Lease for the Term
of the Lease. 

  

	 	(d)	General Assignment. A general assignment by Tenant for the benefit of creditors; 

  

	 	(e)	Bankruptcy. The filing of any voluntary petition in bankruptcy by Tenant, or the filing of an involuntary petition by Tenant’s creditors, which involuntary petition remains undischarged or unstayed for a period of
sixty (60) days. In the event that under applicable law the trustee in bankruptcy or Tenant has the right to affirm this Lease and continue to perform the obligations of Tenant hereunder, such trustee or Tenant shall, in such time period as may
be permitted by the bankruptcy court having jurisdiction, cure all defaults of Tenant hereunder outstanding as of the date of the affirmance of this Lease and provide to Landlord such adequate assurances as may be necessary to ensure Landlord of the
continued performance of Tenant’s obligations under this Lease (including, at a minimum, the maintenance of a security deposit equal to six (6) monthly installments of Gross Rent); 


  
 - 32 - 









	 	(f)	Receivership. The employment of a receiver to take possession of all or substantially all of Tenant’s assets or the Leased Premises, if such receivership remains undissolved for a period of ten (10) Business
Days after creation thereof; 

  

	 	(g)	Attachment. The attachment, execution or other judicial seizure of all or substantially all of Tenant’s assets or the Leased Premises, if such attachment or other seizure remains undismissed or undischarged for a
period of thirty (30) days after the levy thereof; 

  

	 	(h)	Insolvency. The admission by Tenant in writing of its inability to pay its debts as they become due, the filing by Tenant of a petition seeking any reorganization, arrangement, composition, readjustment, liquidation,
dissolution or similar relief under any present or future statute, law or regulation, the filing by Tenant of an answer admitting or failing timely to contest a material allegation of a petition filed against Tenant in any such proceeding, or if
within sixty (60) days after the commencement of any proceeding against Tenant seeking any reorganization, or arrangement, composition, readjustment, liquidation, dissolution or similar relief under any present or future statute, law or
regulation, such proceeding shall not have been dismissed. As used in subsections (d) through (h) above, the term “Tenant” shall be deemed to include any one or more of Tenant and any person or entity that is liable for
Tenant’s obligations under this Lease, including without limitation any Guarantor or general partner of Tenant. 

  

	 	6.02	Remedies Upon Default. 

  

	 	(a)	If an Event of Default occurs, Landlord shall have the right, with or without notice or demand, immediately to terminate this Lease, and at any time thereafter recover possession of the Leased Premises or any part
thereof and expel and remove therefrom Tenant and any other person occupying the same, by notice, by entry or by any other lawful means, and again repossess and enjoy the Leased Premises without prejudice to any of the remedies that Landlord may
have under this Lease, or at law or equity by reason of Tenant’s default or of such termination. 

  

	 	(b)	Even though Tenant has breached this Lease, this Lease and the right to recover Rent as it becomes due shall continue in effect for so long as Landlord does not terminate this Lease under Section 6.02(a) hereof.
Acts of maintenance, preservation or efforts to lease the Leased Premises or the appointment of a receiver upon application of Landlord to protect Landlord’s interest under this Lease shall not constitute an election to terminate Tenant’s
right to possession. 

  

	 	6.03	 Damages Upon Termination. Should Landlord terminate this Lease pursuant to the provisions of Section 6.02(a) hereof, Landlord shall have
all the rights and remedies of a landlord in law or in equity. Upon such termination, in addition to any other rights and remedies of a Landlord may be entitled under applicable law, Landlord shall be entitled to recover from Tenant: (i) the
worth at the time of award of the unpaid Rent and other amounts which had been earned at the time of termination; (ii) the worth at the time of award of the amount by which the unpaid




  
 - 33 - 









	 	
Rent which would have been earned after termination until the time of award exceeds the amount of such Rent loss that the Tenant proves could have been reasonably avoided; (iii) the worth at
the time of award of the amount by which the unpaid Rent for the balance of the Term after the time of award exceeds the rental value of the Leased Premises for the balance of the Term, taking into account reasonable projections of vacancy and the
time required to re-lease the Leased Premises of at least six months; and (iv) any other amount necessary to compensate Landlord for all damages proximately caused by Tenant’s failure to perform its obligations under this Lease, provided
that Tenant shall not be liable for consequential damages (which term shall not be construed to apply to damage remedies expressly set forth in this Article 6 or Section 8.02). Tenant further covenants, as an additional cumulative obligation
after any such termination, to punctually pay to Landlord all sums and perform all obligations which Tenant covenants in this Lease to pay and to perform, as if this Lease had not been terminated. In calculating the amounts to be paid by Tenant
pursuant to this Section 6.03, Tenant shall be credited with any amount paid to Landlord pursuant to this Section 6.03 and also (in respect of the amounts referred to in (i) and (ii)) the net proceeds of rent obtained by Landlord by
reletting the Leased Premises through the time of award, after deducting all Landlord’s reasonable expenses in connection with such reletting, including, without limitation, all reasonable repossession costs, brokerage commissions, fees for
legal services and expenses of preparing the Leased Premises for reletting, it being agreed by Tenant that Landlord may (x) relet the Leased Premises or any part thereof for a term or terms which may at Landlord’s option be equal or less
than or exceed the period which would otherwise have constituted the balance of the Term and may grant such concessions and free rent as Landlord in its reasonable judgment considers advisable or necessary to relet the same and (y) make such
alterations, repairs and decorations in the Leased Premises as Landlord in its reasonable judgment considers advisable or necessary to relet the same, and no action of Landlord in accordance with the foregoing or failure to relet or collect rent
under Landlord’s reletting of the Leased Premises shall operate or be construed to release or reduce Tenant’s liability as aforesaid. The “time of award” shall refer to such time as (I) Tenant shall, as a settlement of the
amounts due pursuant to this Section 6.03, pay to Landlord such sums pursuant to a written agreement in form and substance satisfactory to Landlord, or (II) the date on which a judgment shall be entered in a court of competent jurisdiction to
the effect that Tenant shall pay Landlord the amounts due and owing pursuant to this Section 6.03. The “worth at the time of award” of the amounts referred to in (i) and (ii) shall mean such amounts together with interest at
the lesser of the prime rate of interest from time to time published in the Wall Street Journal plus four percent per annum or the maximum rate allowed by law. The “worth at the time of award” of the amount referred to in (iii) shall
mean such amounts as computed by reference to competent appraisal evidence or the formula prescribed by and using the Federal Reserve Discount Rate (as from time to time published in the Wall Street Journal). 


If the Lease is terminated, Landlord’s actual damages hereunder shall be subject to mitigation by the amount of the damages that Tenant
proves in a final judicial determination would have been avoided by Landlord in the exercise of commercially reasonable efforts to relet the Leased Premises; provided that such reasonable efforts shall not require Landlord (i) to solicit or
negotiate with prospective new tenants until such time as Landlord obtains full and complete possession of the Leased Premises, free of any claim to the Leased Premises or any portion thereof by Tenant and its successors, all subtenants, and other
parties claiming under or through Tenant, (ii) to relet all or part of the Leased Premises 

  
 - 34 - 








 
prior to leasing any other space in the Building then available or scheduled to become available, (iii) to relet all or any part of the Leased Premises to tenants that are not high quality
tenants or that would be inconsistent with Landlord’s leasing requirements, objectives, or plans, including without limitation the development and leasing of the Building in a harmonious manner with an appropriate mix of uses, tenants, floor
areas, terms of tenancies, and the like, (iv) to expend any amounts on tenant improvements or other leasing costs in excess of the levels in Landlord’s budget or leasing guidelines for the Building, or (v) to offer to relet all or
part of the Leased Premises at a rental rate below the rate that Landlord determines to be the prevailing market rate for the space (Tenant agreeing, however, that Landlord may in its discretion relet all or part of the Leased Premises on any terms,
whether above or below such market rate or the rental rate payable hereunder, and that Tenant has no claim to any net reletting proceeds in excess of the rent payable hereunder). Tenant’s liability hereunder shall not be diminished or reduced
if, or to the extent, that such efforts of Landlord to relet the Leased Premises are unsuccessful. 
  

	 	6.04	Computation Of Rent For Purposes Of Default. For purposes of computing unpaid Rent which would have accrued and become payable under this Lease pursuant to the provisions of Section 6.03, unpaid Rent shall
consist of the sum of: 

  

	 	(1)	the total Net Rent for the balance of the Term, plus 

  

	 	(2)	a computation of Tenant’s Proportionate Share of the Operating Cost and Impositions for the balance of the Term, the assumed Operating Cost for the calendar year of the default and each future calendar year in the
Term to be equal to the Operating Cost for the calendar year prior to the year in which the default occurs compounded at a per annum rate equal to the mean average rate of inflation for the preceding two (2) calendar years as determined by the
United State Department of Labor, Bureau of Labor Statistics Consumer Price Index (All Urban Consumers, All Items, 1967 equals 100) for the Metropolitan Area or Region of which Boston, Massachusetts is a part. If such Index is discontinued or
revised, the average rate of inflation shall be determined by reference to the index designated as the successor or substitute index by the government of the United States. 


 

	 	6.05	Liquidated Damages. In lieu of the damages provided for in Section 6.03, Landlord, at its sole option, may by written notice to Tenant, at any time after this Lease is terminated pursuant to
Section 6.02(a) or is otherwise terminated for breach of any obligation of Tenant, elect to recover, and Tenant shall thereupon pay, as liquidated damages, an amount equal to the aggregate of Gross Rent that would have been due for the one-year
period commencing on the date of such termination (or, if lesser, the remainder of the Term), plus the amount of Gross Rent accrued and unpaid at the later of (i) the time of any such termination, or (ii) the time when Tenant vacates the
Leased Premises, and less the amount of any recovery by Landlord under the provisions of Section 6.03. 

  

	 	6.06	Rights of Landlord In Bankruptcy. Nothing contained in this Lease shall 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 proceeding in which, the damages are to be proved, whether or not the amount be greater, equal to, or less than the
amount of the loss or damages referred to in this Article 6. 


  
 - 35 - 









	 	6.07	Late Charge. In addition to its other remedies, Landlord shall have the right to add to the amount of any payment required to be made by Tenant hereunder, and which is not paid on or before the date the same is
due, an amount equal to the greater of (a) Two Hundred Fifty Dollars ($250.00) or (b) one percent (1.0%) of the delinquency, for each month or portion thereof that the delinquency remains outstanding, the parties agreeing that
Landlord’s damage by virtue of such delinquencies would be difficult to compute and the amount stated herein represents a reasonable estimate thereof. (Notwithstanding the foregoing, such late charge shall not apply to the first delinquency
during any twelve-month period during the Term, if Tenant cures the delinquency within five (5) Business Days after written notice from Landlord.) The late charge shall be due upon demand by Landlord. Tenant shall reimburse Landlord for all
costs and expenses (including reasonable attorney’s fees) incurred by Landlord to recover the late charges due hereunder. 


ARTICLE 7. APPRAISAL 
  

	 	7.01	Appraisal Of Fair Market Rent. In the event that Tenant disputes the amount claimed by Landlord as Fair Market Net Rent, and such dispute cannot be resolved by mutual agreement, the dispute shall be submitted to
the appraisal process hereinafter set forth. The amount of Fair Market Net Rent determined pursuant to such appraisal process shall be final and binding between the parties. The appraisal process shall be conducted as follows: 


 

	 	(a)	Tenant shall make demand for appraisal in writing within thirty (30) days after service of Landlord’s determination of Fair Market Net Rent is given under the terms of this Lease (or, if later, by the date ten
(10) days after Landlord gives Tenant a reminder notice as to the requirement of such demand for appraisal, which notice Landlord may give any time after the date that is fifteen (15) days after service of Landlord’s determination of
Fair Market Net Rent), specifying therein the name and address of the person to act as the appraiser on its behalf. The appraiser shall be a real estate appraiser with at least ten years’ experience in the field and a qualified member of the
American Institute of Real Estate Appraisers, or any successor of such Institute (or if such organization or successor shall no longer be in existence, a recognized national association or institute of land appraisers) familiar with the fair market
rent of first-class commercial office space in Comparable Buildings in Downtown Boston. Failure on the part of Tenant to make a timely and proper demand for such appraisal shall constitute a waiver of the right thereto. Within ten (10) Business
Days after the service of the demand for appraisal, Landlord shall give notice to Tenant, specifying the name and address of the person designated by Landlord to act as appraiser on its behalf who shall be similarly qualified. If Landlord fails to
notify Tenant of the appointment of its appraiser, within or by the time above specified, then the Tenant may thereafter send a second notice to Landlord indicating such failure and requesting Landlord to appoint such an appraiser. If Landlord fails
to notify Tenant of the appointment of its appraiser within ten (10) Business Days after the giving of such second notice by Tenant then the appraiser appointed by Tenant shall be the sole appraiser to determine the issue. 


  
 - 36 - 









	 	(b)	In the event that two (2) appraisers are chosen pursuant to Section 7.01(a) above, the appraisers so chosen shall meet within ten (10) Business Days after the second appraiser is appointed and, if within
ten (10) Business Days after such first meeting the two appraisers shall be unable to agree upon a determination of Fair Market Net Rent, they, themselves, shall appoint a third appraiser, who shall be a competent and impartial person with
qualifications similar to those required of the first two appraisers. In the event they are unable to agree upon such appointment within five (5) Business Days after expiration of said ten (10) day period, the third appraiser shall be
selected by the parties themselves, if they can agree thereon, within a further period of ten (10) Business Days. If the parties do not so agree, then either party, on behalf of both, may request appointment of such a qualified person by an
officer of the Greater Boston Real Estate Board in Boston. The three (3) appraisers shall decide the dispute, if it has not previously been resolved, by following the procedure set forth in Section 7.01(c) below. 


 

	 	(c)	Where the issue cannot be resolved by agreement between the two appraisers selected by Landlord and Tenant or settlement between the parties during the course of the appraisal process, the issue shall be resolved by the
three appraisers in accordance with the following procedure. The appraiser selected by each of the parties shall each state in writing his determination of the Fair Market Net Rent, supported by the reasons therefor, with counterpart copies to each
party. The appraisers shall arrange for a simultaneous exchange of such proposed determinations. The role of the third appraiser shall be to select which of the two proposed determinations most closely approximates his own determination of Fair
Market Net Rent. The third appraiser shall have no right to propose a middle ground or any modification of either of the two proposed determinations. The determination he chooses as most closely approximating his determination shall constitute the
decision of the appraisers and be final and binding upon the parties. 

  

	 	(d)	This provision for determination by appraisal shall be specifically enforceable to the extent such remedies are available under applicable law, and any determination hereunder shall be final and binding upon the parties
hereto, and either party shall have the right to enter judgment thereon, unless otherwise provided by applicable law. If a determination of Fair Market Net Rent is to be made pursuant to this Section 7.01, Landlord and Tenant shall each pay for
the fees and disbursements of any appraiser appointed by it and shall share equally in the fees and expenses of any third appraiser. 

  

	 	(e)	In the event of a failure, refusal or inability of any appraiser to act, his successor shall be appointed by him, but in the case of the third appraiser, his successor shall be appointed in the same manner as provided
for appointment of the third appraiser. 

 ARTICLE 8. MISCELLANEOUS 

 

	 	8.01	No Waiver. Failure of Landlord or Tenant to declare any default immediately upon occurrence thereof, or delay in taking any action in connection therewith, shall not waive such default, but Landlord or Tenant, as
the case may be, shall have the right to declare any such default at any time thereafter. 


  
 - 37 - 









	 	8.02	Holding Over. In the event of holding over by Tenant after expiration or termination of this Lease without the written consent of Landlord, Tenant shall pay, for each month or partial month of hold-over tenancy,
an amount equal to 150% of the greater of the Gross Rent for the month immediately preceding the end of the Term or the then fair market Gross Rent for the Leased Premises, together with such other amounts as may become due hereunder. No holding
over by Tenant after the Term shall operate to extend the Term. In the event of any unauthorized holding over that continues for more than thirty (30) days, Tenant shall reimburse Landlord for all damages (including as a result of loss of a

Leased Premises and whether Landlord will suffer adverse economic consequences as generally described in the notice if Tenant does not surrender the Leased Premises by the scheduled Term Expiration Date), losses, costs and expenses, including

such provision to persons or circumstances other than those as to which it is invalid or unenforceable, shall not be affected thereby, and each provision of this Lease shall be valid and shall be enforceable to the fullest extent permitted by law.


  

	 	8.06	 Notices. All notices, demands, consents and approvals which may be or are required to be given by either party to the other hereunder shall be

prepaid, and addressed to the party to be notified at the address for such party specified on the Basic Lease Information sheet, or to such other place as the party to be notified may from time to time designate by at least fifteen (15) days

	 	8.09.	Applicable Law. All rights and remedies of Landlord and Tenant under this Lease shall be construed and enforced according to the laws of the Commonwealth of Massachusetts. 


 

	 	8.10	Time Of The Essence. Time is of the essence for each and every covenant of Tenant herein contained. 

  

	 	8.11	Submission Not An Option. The submission of this Lease for examination does not constitute a reservation of or option for the Leased Premises or an offer to lease, it being understood and agreed that neither
Landlord nor Tenant shall be legally bound with respect to the leasing of the Leased Premises unless and until this Lease has been executed and delivered by both Landlord and Tenant. 


 

	 	8.12	Brokerage. Tenant and Landlord each warrant to the other that it has had no dealings with any broker or agent in connection with this Lease other than the broker(s) named in Basic Lease Information, and each

agent (except any Brokers named in the Basic Lease Information Sheet, whose fees and expenses shall be paid in full by Landlord pursuant to a separate agreement with each such Broker) arising out of the warranting party’s dealings in connection
with this Lease or the negotiation thereof. 

  

	 	8.13	Waiver Of Jury Trial. Landlord and Tenant hereby waive trial by jury in any action, proceeding or counterclaim brought by either of the parties hereto against the other, on or in respect of any matter whatsoever

be entitled to 



  
 - 39 - 









	 	
the restraint by injunction of the violation or attempted or threatened violation of any of the covenants, conditions or provisions of this Lease or to a decree compelling specific performance of
any such covenants, conditions or provisions. 

  

	 	8.16	Failure To Enforce; Accord and Satisfaction. The failure of Landlord or Tenant to seek redress for violation of, or to insist upon strict performance of any covenant or condition of this Lease, or with respect to
such failure of Landlord to enforce any of the rules and regulations referred to herein, whether heretofore or hereafter adopted by Landlord, 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 the original violation, nor shall the failure of Landlord to enforce any of said rules and regulations. The receipt by Landlord of Rent with knowledge of the breach of any covenant of
this Lease shall not be deemed a waiver of such breach. No provision of this Lease shall be deemed to have been waived by either party, unless such waiver shall be in writing and signed by such party. No consent or waiver, express or implied, by
Landlord to 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. Unless Landlord otherwise notifies Tenant in writing, no acceptance by Landlord of a
lesser sum than all Gross Rent and other charges then due shall be applied or deemed to be applied except as follows: first, to charges due under Section 6.07; and second, to the installments of Gross Rent and other charges most recently due.
No endorsement or statement by Tenant on or accompanying any check or payment shall alter the application of such check or payment as set forth above. No such endorsement or statement shall 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 all amounts due or pursue any other remedy provided in this Lease. The delivery of keys to Landlord or to Landlord’s managing agent shall not
operate as a termination of this Lease or a surrender of the Leased Premises. 

  

	 	8.17	Substitution. Landlord shall have the right to substitute the entire Leased Premises, which shall not be before the commencement of the third Lease Year, upon all of the following terms, covenants and condition:


  

	 	(a)	The Substituted Leased Premises (“Substituted Leased Premises”) must constitute space on the Boylston Street side of the Building that is on a floor not lower than the Leased Premises. The right of
substitution may only be exercised if the Substituted Leased Premises designated by Landlord are similar or superior in area, configuration, and appropriateness for Tenant’s purposes and the substitution is made for the purpose of accommodating
a tenant who will occupy the entire floor on which the Leased Premises are located. 

  

	 	(b)	Landlord shall pay the entire cost of moving Tenant, its property and equipment to the Substituted Leased Premises and shall, without cost or expense to Tenant, improve the new Leased Premises with improvements
substantially similar to and of the same quality and of the same standard as those located in the Leased Premises to be vacated and pay for all expenses reasonably incurred by Tenant in connection with such substitution. 


 

	 	(c)	 All of the other terms, covenants and conditions of the Lease shall remain unchanged and in full force and effect with respect to the Substituted
Leased Premises, except that the Basic Lease Information sheet shall be revised: (i) to identify the floor of the Substituted Leased Premises; (ii) to state as the Net 



  
 - 40 - 









	 	
Rentable Area the square footage of the Substituted Leased Premises as determined by Landlord’s architect, provided that the total Base Rent payable by Tenant shall not increase as a result
of such substitution and, if the Substituted Leased Premises are smaller, Base Rent shall be payable on such smaller area; and (iii) to revise, as appropriate, Tenant’s Proportionate Share. 


 

	 	8.18	Notice Of Lease. Tenant agrees not to record this Lease, but on the request of either party hereto, both parties hereto shall execute and deliver (i) if appropriate, a notice of this Lease in form
appropriate for recording or registration, (ii) an agreement setting forth the Term Commencement Date, (iii) a notice in form appropriate for recording or registration of any amendment of this Lease, (iv) an agreement by Tenant to
make payments and give notices to whatever individual or entity shall be designated by Landlord for receiving any such notice or payment and to comply with the provisions of any assignment of rents granted to the holder of any Mortgage, and
(v) if this Lease is terminated before the expiration of the Term, an instrument in form appropriate for recording or registration pursuant to which Tenant acknowledges the date of termination. If Tenant unreasonably refuses to execute any of
the notices, amendments, agreements and instruments provided for in the immediately preceding sentence, within ten (10) Business Days after Landlord gives notice to Tenant requesting execution of the same, Landlord may effect such execution on
behalf of Tenant as Tenant’s attorney-in-fact and Tenant hereby grants to Landlord an irrevocable power of attorney to execute on behalf of Tenant each such notice, amendment, agreement and instrument, which power is coupled with an interest.


  

	 	8.19	Consents. Tenant hereby waives any claim for damages against Landlord which it may have based upon any assertion that Landlord has unreasonably withheld or unreasonably delayed any such consent or approval so
long as Landlord has acted in good faith, and Tenant agrees that its sole remedy shall be an action or proceeding to enforce any such provision or for specific performance, injunction or declaratory judgment. In the event of a determination
favorable to Tenant, the requested consent or approval shall be deemed to have been granted; however, Landlord shall have no liability to Tenant for its good faith refusal or failure to give such consent or approval. 


 

	 	8.20	Intentionally omitted. 

  

	 	8.21	Tenant’s Authorized Representative. Tenant designates the person named from time to time as Tenant’s Authorized Representative to take all acts of Tenant hereunder. Landlord may rely on the acts of such
Tenant’s Authorized Representative without further inquiry or evidence of authority. Tenant’s Authorized Representative shall be the person so designated in Basic Lease Information and such successors as may be named from time to time by
the then current Tenant’s Authorized Representative or by Tenant’s president. 

  

	 	8.22	 Assignment of Rents. If at any time Landlord assigns this Lease or the rents payable hereunder to the holder of any Mortgage, whether such
assignment is conditional in nature or otherwise, (i) such assignment to the Mortgagee shall not be deemed an assumption by the Mortgagee of any obligations of Landlord hereunder unless such Mortgagee shall, by written notice to Tenant,
specifically otherwise elect; (ii) except as aforesaid, the Mortgagee shall be treated as having assumed Landlord’s obligations hereunder (subject to Section 4.13) only upon foreclosure of its mortgage (or voluntary conveyance by deed
in lieu thereof) and the taking of possession of the Leased Premises and, with respect to obligations 



  
 - 41 - 









	 	
regarding return of any security deposit, only upon receipt of the funds constituting such security deposit; and (iii) if Tenant alleges that Landlord is in default under this Lease, Tenant
shall give the Mortgagee a copy of any notice of default served upon Landlord and, if Landlord fails to cure such default within the time provided herein or by law or such additional time as may be provided in such notice to Landlord, the Mortgagee
shall have thirty (30) days after the end of Landlord’s cure period to cure such default (or such additional time as may be necessary to cure such default, if within such thirty day period the Mortgagee has commenced and is diligently
pursuing the remedies necessary to effect such cure), in which event (except as set forth in Section 3.01(c)) Tenant shall have no right to an abatement of Rent or to terminate this Lease with respect to such default while such remedies are
being diligently pursued by the Mortgagee. 

  

	 	8.23	Tenant Confirmations. Tenant represents and warrants to Landlord that (a) the person(s) executing this Lease on behalf of Tenant are duly authorized and have full power to execute and deliver this Lease,
(b) Tenant has no claim, offset, or defense against the enforcement of the Lease in accordance with its terms, and (c) Tenant is not acting, directly or indirectly, for or on behalf of any person, group, entity, or nation named by any
Executive Order or the United States Treasury Department as a terrorist, “Specially Designated National and Blocked Person”, or other banned or blocked person, group, entity, nation, or transaction pursuant to any law, order, rule, or
regulation that is enforced or administered by the Office of Foreign Assets Control and that it is not engaged in this transaction, directly or indirectly, on behalf of, or instigating or facilitating this transaction, directly or indirectly, on
behalf of any such person, group, entity, or nation. 

 ARTICLE 9. OPTIONS 

 

	 	9.01	Extension Option. Tenant shall have the option to extend the Term of the Lease for one (1) additional period of five (5) years (the “Extension Term”), by written notice given to Landlord at
least twelve (12) months before the scheduled expiration of the initial Term, on the terms set forth below (the “Extension Option”). Tenant’s notice exercising the Extension Option must be unconditional and irrevocable in order
to be effective. Failure to timely deliver Tenant’s notice exercising the Extension Option shall constitute Tenant’s waiver of the Extension Option. Tenant’s lease of the Leased Premises during the Extension Term shall be on all of
the terms and conditions of this Lease in effect on the last day of the expiring Term, except that Net Rent during the Extension Term shall be the Fair Market Net Rent as determined hereunder. Tenant shall have no option to extend the Term beyond
the end of the Extension Term. Landlord may give Tenant notice of Landlord’s determination of the Fair Market Net Rent at any time after the date eighteen (18) months prior to the date the Extension Term is scheduled to commence and, if so
requested by Tenant on thirty days prior notice, shall provide such determination no later than the date thirteen (13) months prior to the date the Extension Term is scheduled to commence. Any dispute over Fair Market Net Rent shall be resolved
in accordance with Article 7. All references in this Lease to “Term” shall mean the initial Term as extended by any Extension Term. 


For any part of the Extension Term during which the Net Rent is in dispute hereunder, Tenant shall make payment on account of Net Rent at the
rate estimated by Landlord, and the parties shall adjust for any overpayments or underpayments upon the issuance of the arbitrators’ decision. The failure by the parties to complete the process contemplated under this Section 9.01 prior to


  
 - 42 - 








 
commencement of the Extension Term shall not affect the continuation of the Term or the parties’ obligation to make any adjustments for any overpayments or underpayments for the Net Rent due
for the Extension Term promptly after the determination thereof is made. 
 If Tenant shall exercise the Extension Option in accordance with
this Section 9.01, the provisions of this Section shall be self-operative, but upon request by either party after determination of the Net Rent for the Extension Term, the parties shall execute an agreement specifying the Net Rent for the
Extension Term and acknowledging the extension of the Term. 
 Notwithstanding any provision of this Section to the contrary, Tenant’s
option to extend the Term shall be void, at Landlord’s election, if (i) Tenant is in default hereunder, after any applicable notice and cure periods have expired, at the time Tenant elects to extend the Term or at the time the Term would
expire but for such extension, or (ii) any transfer under Section 4.06 has occurred on or before either such time, other than a transfer to an Affiliate or sublease(s) covering less than half of the Leased Premises in the aggregate. 

 

	 	9.02	Right of First Offer. “First Offer Space” shall mean all or part of the balance of the 12th floor of the Building (subject to the exclusions in Section 1.01) (which area contains, in the aggregate,
the total square feet of Net Rentable Area set forth for the Expansion Premises in the Basic Lease Information Section of this Lease), which Landlord from time to time determines is available for lease to a third party, in such location and
configuration as may be designated by Landlord. If Tenant does not timely exercise the Initial Expansion Right under Section 2.01(c), then Landlord shall, before entering into the next lease of any First Offer Space with a third party during
the five-(5)-year period commencing on March 1, 2013 (the “ROFO Period”), advise Tenant of the economic and other material terms and conditions under which Landlord is willing to lease such First Offer Space to Tenant
(“Landlord’s Notice”), which shall be for a term that is co-terminus with the Term of this Lease (as the same may have been extended under Section 9.01) provided that at least three (3) years remain in the Term of this Lease
(as the same may have been extended under Section 9.01) after the scheduled rent commencement date for such First Offer Space. In no event shall this Section 9.02 apply to any First Offer Space available for delivery within the last
three (3) years of the Term (as the same may have been extended under Section 9.01). 

 Within ten
(10) Business Days after a Landlord’s Notice is given, Tenant may, by written notice delivered to Landlord, either (a) agree to lease the First Offer Space described in Landlord’s Notice, in its entirety only, for Tenant’s
own use on the terms and conditions set forth in Landlord’s Notice, (b) offer to lease such First Offer Space for its own use at a Net Rent rate specified in Tenant’s response and otherwise on the other terms and conditions set forth
in Landlord’s Notice, or (c) decline to lease such First Offer Space. Tenant’s notice under clause (a) or (b) must be unconditional and irrevocable in order to be effective. The failure by Tenant to timely respond as
aforesaid shall be deemed Tenant’s rejection of Landlord’s Notice under clause (c). If Tenant declines to lease such First Offer Space (or is deemed to reject Landlord’s Notice) as aforesaid, then Tenant shall have no further
rights with respect to such First Offer Space. However, if Tenant timely offers to lease the First Offer Space in accordance with clause (b) above and Landlord does not accept such offer by Tenant, then Landlord shall deliver to


  
 - 43 - 








 
Tenant a new Landlord’s Notice prior to entering into the next lease of such First Offer Space during the ROFO Period at an effective Net Rent rate (taking into account, among other things,
the Net Rent rate, term length, any free rent or other financial concessions, and discount factor, all as determined by Landlord) that is equal to or less than that specified in Tenant’s offer. 

If Tenant timely accepts Landlord’s Notice (or if Landlord accepts Tenant’s offer) for a First Offer Space under the preceding
paragraph, the First Offer Space in question shall, subject to the following paragraph below and without further action by the parties, be leased by Tenant on the accepted terms and otherwise on all of the terms of the Lease in effect immediately
prior to such expansion that are not inconsistent with the terms set forth in Landlord’s Notice, provided that, at Landlord’s request, Landlord and Tenant shall promptly execute and deliver an amendment to the Lease confirming such
expansion of the Leased Premises, the accepted rental rate and other terms, and the estimated date on which the Leased Premises are to be expanded pursuant to this Section with a provision for establishing the effective date of such expansion based
on actual delivery. If Tenant timely accepts Landlord’s Notice (or if Landlord accepts Tenant’s offer) under the preceding paragraph, Landlord shall use reasonable efforts to deliver the First Offer Space on or before the estimated
delivery date, but Landlord’s failure to deliver, or delay in delivering, all or any part of the First Offer Space, for any reason, shall not give rise to any liability of Landlord, shall not alter Tenant’s obligation to accept such space
when delivered, shall not constitute a default of Landlord, and shall not affect the validity of the Lease. 
 Notwithstanding any provision
of this Section to the contrary, Tenant’s rights under this Section shall be void, at Landlord’s election, if (i) Tenant is in default hereunder, after any applicable notice and cure periods have expired, at the time Landlord would
deliver a Landlord’s Notice to Tenant, or at the time Tenant elects to lease any First Offer Space under this Section, or at the time any First Offer Space would be added to the Leased Premises, or (ii) any assignment or sublease(s)
totaling more than 5,000 square feet of the Net Rentable Area of the Leased Premises in the aggregate under Section 4.06 has been entered into prior to either such date (other than a sublease or assignment to an Affiliate or any office-sharing
arrangements with Tenant Related Parties in compliance with Section 4.06), or Tenant (including its Affiliate and Tenant Related Parties under Section 4.06) otherwise does not occupy the entire Leased Premises (other than up to 5,000
square feet of Net Rentable Area) as of such date. Tenant’s rights under this Section are personal to the Tenant originally named in this Lease, together with any Affiliate of such Tenant to which this Lease may be assigned under
Section 4.06.

 EXHIBIT D 

Letter of Credit Requirements 

The letter of credit shall be for the amount specified in the Lease to which this Exhibit is attached (as renewed, replaced, and/or reduced
pursuant to the Lease or this Exhibit, the “Letter of Credit”). The Letter of Credit (i) shall be irrevocable and shall be issued by a commercial bank reasonably acceptable to Landlord that has an office in Boston, Massachusetts, New
York City, or other location approved by Landlord, (ii) shall require only the presentation to the issuer of a certificate of the holder of the Letter of Credit stating that Landlord is entitled to draw on the Letter of Credit pursuant to the
terms of the Lease, (iii) shall be payable to Landlord (or its successor in interest as the Landlord upon any transfer of the Letter of Credit in accordance herewith) and shall be transferable to any such successor or any lender holding a
collateral assignment of Landlord’s interest in the Lease, at no cost to Landlord or such transferee, (iv) shall be for an initial term of not less than one year and contain a provision that such term shall be automatically renewed for
successive one-year periods unless the issuer shall, at least forty five (45) days prior to the scheduled expiration date, give Landlord notice of such nonrenewal, and (v) shall otherwise be in form and substance reasonably acceptable to
Landlord. In the event that the issuer ceases to be reasonably acceptable to Landlord, due to a deterioration in its financial condition or change in status that threatens to compromise Landlord’s ability to draw on the Letter of Credit, then
Tenant shall provide a replacement Letter of Credit satisfying the terms of this Exhibit within thirty (30) days after notice of such event. Notwithstanding the foregoing, the term of the Letter of Credit for the final period shall be for a
term ending not earlier than the date thirty (30) days after the last day of the Term. 
 Landlord shall be entitled to draw upon the
Letter of Credit for its full amount or any portion thereof if (a) Tenant shall fail to perform any of its obligations under this Lease after the expiration of any applicable notice and cure period (or fail to perform any of its obligations
under the Lease and transmittal of a default notice or running of any cure period is barred or tolled by applicable law), or (b) not less than 30 days before the scheduled expiration of the Letter of Credit, Tenant has not delivered to Landlord

of this Lease in a bankruptcy proceeding commenced by or against Tenant. Landlord may, but shall not be obligated to, apply the amount so drawn to the extent necessary to cure Tenant’s failure to pay. Any amount drawn in excess of the amount
applied by Landlord to cure any such failure shall be held by Landlord as a cash security deposit under Section 4.17 of the Lease for the performance by Tenant of its obligations under the Lease. After any such application by Landlord of the
Letter of Credit or security deposit, Tenant shall reinstate the Letter of Credit to the amount originally required to be maintained under the Lease, upon demand (it being understood that such reinstatement obligation shall take into account both
the then undrawn amount of the Letter of Credit and any unapplied cash security deposit then held by Landlord). If Tenant is then not in default under the Lease (after applicable notice and cure period), within thirty (30) days after the
expiration or sooner termination of the Term the Letter of Credit and any security deposit, to the extent not applied, shall be returned to the Tenant, without interest. 

  
 - 61 -

a transferee. Tenant further covenants that it will not assign or encumber or attempt to assign or encumber the Letter of Credit or the monies deposited herein as security, and that neither Landlord nor its successors or assigns shall be bound by
any assignment, encumbrance, attempted assignment or attempted encumbrance.
