WHEREAS, the following facts are true: 

A. By Lease Agreement dated July 2, 2008 (“Master Lease”), Sublandlord leases approximately 75,495 rentable square feet of
space located on the Fifth and Sixth Floors at Five Wall Street, Burlington, Massachusetts 01803 (“Leased Premises”) from Burlington Office Park V Limited Partnership (“Landlord”). A copy of the Master Lease is attached hereto as
Exhibit A. 
 B. Sublandlord and Subtenant now desire to enter into a sublease whereby Subtenant will lease approximately 37,481
rentable square feet consisting of the entire Sixth Floor of the Leased Premises as defined in the Master Lease from Sublandlord (“Subleased Premises”), upon and subject to the terms, covenants and conditions herein contained. 

NOW, THEREFORE, in consideration of the premises, the mutual covenants and terms contained herein, and other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 
 1. Sublease of Subleased
Premises. Sublandlord hereby subleases to Subtenant, and Subtenant hereby takes from Sublandlord the Subleased Premises and agrees to be bound by all rights and obligations of Sublandlord as Tenant under the Master Lease, as such apply to the
Subleased Premises. 







 2. Term. The term of this Sublease is approximately ninety four (94) months
(“Sublease Term”) commencing on the date on which both of the following have occurred: (i) Sublandlord’s substantial completion of any work as outlined and required in Article 3 below, and delivery of the Subleased
Premises to Subtenant broom-clean and free of all occupants and personal property except as set forth on Exhibit B attached hereto, and (ii) Landlord’s written consent to this Sublease in form reasonably similar to the form attached hereto
(“Commencement Date”), and expiring on the earlier of (a) the permitted termination date under Sublandord’s “Early Termination Option” in Exhibit N of the Master Lease or (b) October 31, 2019 (as applicable,
the “Expiration Date”). Sublandlord and Subtenant shall memorialize in writing, at the request of either, the actual Commencement Date after the same has been established. In the event Sublandlord exercises its “Early Termination
Option” under Exhibit N of the Master Lease, Sublandlord shall notify Subtenant in the same manner as Sublandlord is required to notify Landlord, and Subtenant must vacate the Subleased Premises no later than the first day of month eighty four
(84) of the Master Lease term (November 1, 2015). Neither Sublandlord nor Subtenant shall have any liability or responsibility to the other solely in connection with Sublandlord’s election to exercise its right of early termination,
and any fee due Landlord in connection therewith is the sole responsibility of Sublandlord. If Subtenant has not vacated the Subleased Premises by the Expiration Date, the Subtenant will pay Sublandlord for the Holdover as outlined in
Article 6.1.16 of the Master Lease. Exhibit “F” of the Master Lease is expressly excluded from this Sublease and for purposes of Exhibit “F” and the renewal rights granted therein Subtenant shall not be considered
“Tenant” as otherwise described in Article 7(b) below.

 3. Condition of Subleased Premises. On the Commencement Date, Sublandlord shall deliver
the Subleased Premises, and Subtenant agrees to accept the Subleased Premises, in its “as is” broom clean condition as of the date hereof. Sublandlord shall not be obligated to perform any work or furnish any materials in, to or about the
Subleased Premises in order to prepare the Subleased Premises for use or occupancy by Subtenant or otherwise except as set forth in herein and/or Exhibit C attached hereto. All work performed by Sublandlord under this Section 3 shall be
performed in a good and workmanlike manner in accordance with all applicable laws. Sublandlord, at its cost and prior to the Commencement Date, shall be responsible for demising the Subleased Premises in accordance with the terms of this
Section 3. Sublandlord shall, at its sole cost and expense, barricade the stairwell and remove the video conference equipment in accordance with Exhibit C (the “Stairwell Treatment”) attached hereto. Subtenant shall have no
responsibility for any code regulations/sprinkler/demising work associated with the Stairwell Treatment. Any necessary HVAC and/or electrical demising work shall be performed by Sublandlord at its sole cost and expense so the Subleased Premises
is delivered as its own floor with separate electrical demising and proper HVAC balancing. Furthermore, Sublandlord at its sole cost and expense shall remove all video conferencing equipment from the Premises prior to the date which is 180 days
following the Execution Date (the “Video Equipment Removal Date”). In the event that Sublandlord does not remove such video conferencing equipment by the Video Equipment Removal Date, in addition to the abatement set forth in Article
4, Rent shall abate for one additional day for every day beyond the Video Equipment Removal Date that Sublandlord fails to remove the video conferencing equipment. Subtenant shall have the right to perform modifications to the Subleased Premises
during the course of the Sublease Term in accordance with the Master Lease. Any 

  
 3 








 
improvements will be paid by Subtenant and are subject to both Sublandlord and Landlord’s reasonable approval rights, not to be unreasonably withheld, conditioned, or delayed in the case of
Sublandlord. Subtenant agrees that in executing this Sublease, it has not relied upon any statements, representations, covenants or warranties made by Sublandlord or any person acting on behalf of Sublandlord other than those, if any, expressly set
forth in this Sublease, and on such investigations, examinations and inspections as Subtenant has chosen to make or has made.

 (b) If the Commencement Date shall be other than the first day of a month or the expiration or
sooner termination of the Term is other than on the last day of a month, the monthly installments of Base Rent and any Additional Rent payable hereunder for the last month of the Term shall be prorated on a per diem basis based on the actual number
of days in such month. By way of clarification, if the Commencement Date occurs after January 11, 2012, the 5 months of free rent contemplated under the rent table above shall commence on the Commencement Date and expire 151 days thereafter,
and all subsequent rent increases shall occur on the dates set forth in said rent table, and only the final month will be prorated. 
 (c)
All amounts payable by Subtenant pursuant to this Sublease, including, without limitation, Base Rent, Operating Cost Escalation, and all other costs, charges, sums and deposits payable by Subtenant hereunder (collectively, “Rental”), shall
constitute rent under this Sublease and shall be payable to Sublandlord or its designee at such address as Sublandlord shall from time to time direct in writing. 

(d) Subtenant shall pay the Rental without setoff, offset or deduction of any kind whatsoever and, in the event of Subtenant’s failure to
pay the Rental when due, Sublandlord shall have all of the rights and remedies provided for in the Master Lease in the case of nonpayment of rent. 

5. Liability of Sublandlord. Sublandlord hereby acknowledges that this Sublease does not relieve it from its liability for the payment
of rent and the performance and observance of all of the terms, conditions, covenants and obligations under the Master Lease. Sublandlord further acknowledges that this Sublease shall not be construed to modify, waive, impair, or affect any of the
terms, provisions or conditions of the Master Lease. 

  
 5 








 6. Use. Subtenant shall use and occupy the Subleased Premises for office space and
ancillary uses in accordance with the uses permitted under the Master Lease and for no other purpose. 
 7. Subordination to and
Incorporation of Terms of Master Lease. 
 (a) This Sublease and all of Subtenant’s rights hereunder are and shall remain in all
respects subject and subordinate to (i) all of the conditions and provisions of the Master Lease as such apply to the Subleased Premises (ii) any and all amendments or modifications to the Master Lease or supplemental agreements relating
thereto hereafter made between the Landlord and Sublandlord which do not in any respect contravene any express rights granted to Subtenant hereunder, and (iii) any and all matters to which the tenancy of Sublandlord, as tenant under the Master
Lease, is or may be subordinate as of the date hereof. The foregoing provisions shall be self-operative and no further instrument of subordination shall be necessary to effectuate such provisions. 

(b) Except as otherwise expressly provided in this Sublease, Subtenant assumes and shall keep, observe and perform every term, provision,
covenant and condition on Sublandlord’s part pertaining to the Subleased Premises which is required to be kept, observed and performed pursuant to the Master Lease and which arises or accrues during the Term, except that Subtenant shall have no
obligation to remove alterations installed by Sublandlord or restore the Subleased Premises to any condition other than its condition on the Commencement Date, excluding those alterations specifically requested by Subtenant. The provisions of this
Sublease shall be 

  
 6 








 
interpreted wherever possible so as to be consistent with the provisions of the Master Lease; in the event, however, of an irreconcilable inconsistency, the provisions of this Sublease shall
control. To the extent applicable as provided in this Sublease, wherever in the Master Lease the word “Tenant” appears, for the purposes of this Sublease, the word “Subtenant” shall be substituted, and references to the
“Landlord” shall be deemed to include the “Sublandlord.” 
 (c) With respect to any request for overtime services,
Subtenant may make such request in Sublandlord’s name directly to the Landlord, provided such request is made in writing in accordance with the terms of the Master Lease and a duplicate copy of such request is simultaneously given to
Sublandlord. 
 (d) Sublandlord shall have the same rights and remedies with respect to a breach of this Sublease by Subtenant as the
Landlord has with respect to a breach of the Master Lease, as if the same were more fully set forth at length herein, and Sublandlord shall have, with respect to Subtenant, this Sublease and the Subleased Premises, all of the rights, powers,
privileges and immunities as are had by the Landlord under the Master Lease. Sublandlord herein shall not be responsible for any breach of the Master Lease by the Landlord or any non-performance or
non-compliance with any provision thereof by the Landlord, but Sublandlord shall comply with the provisions of Article 14 hereof. 

(e) Provided Subtenant is not in default under this Sublease (subject to applicable notice and cure periods), Sublandlord covenants and agrees
not to voluntarily cancel or surrender the Master Lease, including without limitation exercising Sublandlord’s termination right under Exhibit N of the Master Lease, or consent to any modification, amendment or supplement to the Master Lease
except as herein permitted, without the prior written consent of Subtenant. If the 

  
 7 








 
Master Lease is terminated for any reason whatsoever, whether by operation of law or otherwise, except through the default of Sublandlord, Sublandlord shall not be liable in any manner whatsoever
for such termination. Sublandlord shall promptly forward to Subtenant any default or termination notice with respect to the Master Lease received by Sublandlord and this Sublease shall terminate in the event of any such termination of the Master
Lease. A termination of the Master Lease due to the default of Sublandlord, other than a default caused by Subtenant under this Sublease, shall be considered a voluntary cancellation or surrender of the Master Lease under this Article 7. 

8. Attornment. If the Master Lease and Sublandlord’s leasehold in the Subleased Premises shall be terminated, other than as a
result of casualty or condemnation or sale in lieu thereof, Subtenant shall, if so requested in writing by Landlord, attorn to Landlord and shall, during the Term, perform all of the terms, covenants and conditions of this Sublease on the part of
Subtenant to be performed. In the event of any such attornment, Landlord shall not be (a) liable for any act or omission or default of any prior sublessor (including, without limitation, Sublandlord); or (b) subject to any offsets or
defenses which Subtenant might have against any prior sublessor (including without limitation, Sublandlord); or (c) bound by any rent or additional rent which Subtenant might have paid for more than the current month to any prior sublessor
(including, without limitation, Sublandlord); or (d) bound by any amendment or modification of this Sublease made without Landlord’s consent. The foregoing shall be self-operative without the necessity of the execution of any further
instruments by Subtenant but Subtenant agrees, upon the demand of Landlord, to execute, acknowledge and deliver any instrument or instruments confirming such attornment. 

  
 8 








 9. Right of First Offer. In the event Sublandlord elects to vacate the Fifth (5th) Floor Premises, Sublandlord will provide Subtenant with written notification to that effect. Subtenant shall have a Right of First Offer to sublease the Fifth (5th) Floor on the same terms (including rent) as set forth in this Sublease, exercisable within fifteen (15) days from the date notification is sent. For clarification purposes, such space
shall be added to the definition of Subleased Premises herein and considered as part thereof, and the applicable rent shall be the actual rent then in effect under Article 4 above during the specific month Subtenant exercises its Right of First
Offer and subleases additional space on the Fifth (5th) Floor. As an example, if Subtenant increases the Subleased Premises in the 33rd
month of this Sublease, the cost per each additional rentable square foot, net of Tenant Electricity, shall be $27.45. 
 10.
Signage. Subtenant will be provided with lobby signage on the building directory and on the 6th Floor at the Subleased Premises per building standards, but notwithstanding anything to the
foregoing contained in this Sublease, the provision of such signage is the sole responsibility of Landlord, and not Sublandlord, subject to Sublandlord’s obligations under Section 14 below. 

11. Quiet Enjoyment. Sublandlord covenants that as long as Subtenant shall pay the Rental due hereunder and shall duly perform all the
terms, covenants and conditions of this Sublease on its part to be performed and observed, Subtenant shall peaceably and quietly have, hold and enjoy the Subleased Premises during the Term without molestation or hindrance by Sublandlord, subject to
the terms, provisions and conditions of the Master Lease and this Sublease. 

  
 9 








 12. Representations, Warranties, and Covenants. 

(a) Sublandlord represents and warrants to Subtenant as follows as of the date of execution and delivery of this Sublease: (i) the Master
Lease is in full force and effect in accordance with, and subject to, all of the terms, covenants, conditions and agreements contained therein; (ii) the Master Lease has not been modified, amended or supplemented; (iii) Sublandlord has not
received any notice of, and is not aware of, any default by the Sublandlord under the Master Lease, which default remains uncured; (iv) Sublandlord holds the entire tenant’s interest in the Subleased Premises under the Master Lease free
and clear of any liens, claims, mortgages, charges or encumbrances, subleases and occupancies (other than this Sublease and the Master Lease), other than matters to which the tenancy of the Sublandlord, as tenant under the Master Lease, is or may be
subordinate; and (v) subject to receipt of approval of the Landlord to this Sublease, Sublandlord has full right, power and authority to enter into this Sublease. 

(b) Subtenant hereby represents and warrants to Sublandlord that the Subtenant has full right, power and authority to enter into this
Sublease. 
 13. Services and Repairs. Notwithstanding anything to the contrary set forth in this Sublease, Sublandlord shall have no
obligation to render or supply any services to Subtenant, including, without limitation (a) the furnishing of electrical energy, heat, ventilation, water, air conditioning, elevator service, cleaning, window washing, or rubbish removal
services, (b) making any alterations, repairs or restorations to the Subleased Premises or the Building, (c) complying with any laws or requirements of any governmental authorities, or (d) taking any action that Landlord has agreed to
provide, make, comply with, or take, or cause to be provided, made, complied with, or taken under the Master Lease (collectively “Services and Repairs”). Subtenant hereby agrees that Subtenant shall look solely to Landlord for the
performance of any and all of such Services and Repairs, subject to the terms and conditions of this Sublease, 

  
 10 








 
including but not limited to Section 14 below, and the Master Lease. Sublandlord hereby grants to Subtenant Sublandlord’s rights under the Master Lease to receive from the Landlord the
Services and Repairs to the extent that Sublandlord is entitled (i) to receive same under the Master Lease, and (ii) to grant same to Subtenant. Sublandlord shall in no event be liable to Subtenant nor shall the obligations of Subtenant
hereunder be impaired or the performance thereof excused because of any failure or delay on the Landlord’s part in furnishing the Services and Repairs, unless such failure or delay results from Sublandlord’s default under the Master Lease
(which default is not caused by or attributable to any corresponding default of Subtenant under this Sublease). 
 14. Enforcement of
Master Lease. Sublandlord shall use reasonable efforts (but shall have no obligation to bring a formal action or proceeding) to enforce on behalf of Subtenant, Sublandlord’s rights under the Master Lease with respect to the Subleased
Premises. Subtenant shall also have the right to take such action in its own name. If (a) any such action against the Landlord in Subtenant’s name is barred by reason of lack of privity,
non-assignability or otherwise, and (b) the failure of Landlord to perform its obligations under the Master Lease would have a material adverse affect upon the Subleased Premises or Subtenant’s
permitted use thereof, then subject to and upon the following terms, Subtenant may bring such action in Sublandlord’ s name and Sublandlord shall execute all documents reasonably requested in connection therewith, provided (i) the same is
without cost and expense to Sublandlord, (ii) Subtenant shall provide the indemnification to Sublandlord required pursuant to its obligations under the Master Lease, and (iii) Subtenant is not in default hereunder. 

15. Assignment and Subleasing. Subtenant shall be permitted to assign the Sublease or sublease all or any portion of the Subleased
Premises during the Sublease Term to any related 

  
 11 








 
entity, parent, subsidiary, or affiliate of Subtenant or any entity which directly or indirectly controls, is controlled by or under common control of the Subtenant or to any corporation or other
entity with succeeds to all or substantially all of the assets and business of Subtenant conducted from the Subleased Premises or to any entity that performs services for Subtenant without having the obligation of securing Sublandlord’s prior
approval or consent (“Related Entities”), though reasonable prior notice to Sublandlord is required. Transfers of stock and other changes of control shall not constitute “assignments” of Subtenant’s interest hereunder.
Subtenant may assign all or sublease all or any portion of the Subleased Premises to any other entity or person upon receipt of Sublandlord’s prior consent, which consent shall be in Sublandlord’s sole discretion. Notwithstanding the
foregoing, nothing contained in this Article XV herein shall be considered a waiver of Sublandlord’s obligations under the Master Lease in connection with any desired assignment or sublease 

If this Sublease is assigned, or if the Subleased Premises or any part thereof is sublet or occupied by someone other than Subtenant,
Sublandlord may, after default by Subtenant, collect rent and other charges from such assignee, subtenant or other occupant, and apply the net amount collected to Rental and other charges herein reserved, but no such assignment, subletting,
occupancy or collection shall be deemed to be a waiver of the requirements of this Article 15 or an acceptance of the assignee, subtenant or other occupant as subtenant under this Sublease. The consent by Sublandlord to an assignment or
subletting shall not in any way be construed to relieve Subtenant from obtaining consent to any further assignment or subletting. No assignment or subletting shall, in any way, release, relieve or modify the liability of Subtenant under this
Sublease and Subtenant shall be and remain liable under all of the terms, conditions, and covenants hereof.

(b) Each party shall look first to any insurance in its favor before making any claim against the other party for recovery for loss or damage
resulting from fire or other casualty. To the extent that such insurance is in force and collectible and to the extent permitted by law, Sublandlord and Subtenant each hereby releases and waives all right to recovery against the other or anyone
claiming through or under the other by way of subrogation or otherwise, and Subtenant also releases and waives all right to recover against Landlord. 

18. Notices. All notices, consents, approvals or other communications (collectively a “Notice”) required to be given under
this Sublease or pursuant to law shall be in writing and, unless otherwise required by law, shall be either personally delivered (against a receipt), or sent by reputable overnight courier service, or given by registered or certified mail, return

 19. Broker and Brokerage Fees. Sublandlord and Subtenant warrant and represent to the
other that they have dealt with no real estate brokers, finders, agents or salesmen in connection with this Sublease, except T3 Advisors and Newmark Knight Frank (collectively, the “Broker”). Each party agrees to hold the other party
harmless from and against all claims for brokerage commissions, finder’s fees, or other compensation made by any other agent, broker, salesman or finder as a consequence of said party’s actions or dealings with any such agent, broker,
salesman, or finder. Sublandlord agrees to pay Broker a brokerage commission pursuant to a separate agreement. 
 20. No Waivers.
Failure by either party in any instance to insist upon the strict performance of any one or more of the obligations of the other party under this Sublease, or to exercise any election herein contained, or acceptance of payment of any kind with
knowledge of a default by the other party, shall in no manner be or be deemed to be a waiver by such party of any defaults or breaches hereunder or of any of its rights and remedies by reason of such defaults or breaches, or a waiver or
relinquishment for the future of the requirement of strict performance of any and all of the defaulting party’s obligations hereunder. 

21. Intentionally Deleted. 

22. Security Deposit. Subtenant shall pay to Sublandlord a security deposit equal to the amount of three (3) months Base Rent to
secure the performance of the Subtenant’s obligations hereunder (the “Security Deposit”). In the event of a default by Subtenant beyond applicable notice and cure periods, Sublandlord may, but shall not be obligated to, apply all or


  
 14 








 
portions of the Security Deposit on account of Subtenant’s obligations hereunder. In the event that Sublandlord applies all or a portion of the Security Deposit to Subtenant’s
obligations hereunder, Subtenant shall be obligated, within ten (10) days of receipt of notice from Sublandlord, to deposit cash with Sublandlord in an amount sufficient to restore the Security Deposit to the full applicable amount as set forth
in this Section. Failure to deposit such cash within such time period shall be a default under the terms of this Sublease. Provided that Subtenant is not in default under this Sublease beyond applicable notice and cure periods on the First Reduction
Date (as defined below) or Second Reduction Date (as defined below) as applicable, the required amount of the Security Deposit shall be reduced to an amount equal to the sum of two (2) months Base Rent on November 1, 2013 (the “First
Reduction Date”), and an amount equal to the sum of one (1) month Base Rent on November 1, 2016 (the “Second Reduction Date”), and Sublandlord shall promptly refund to Subtenant the applicable amount of such Security Deposit
reductions on such dates. Furthermore, provided that Subtenant is not in default under this Sublease beyond applicable notice and cure periods, any balance remaining upon termination or expiration of this Sublease shall be promptly returned to
Subtenant. Subtenant shall not have the right to apply the Security Deposit in payment of the last month’s rent. No interest shall be paid by Sublandlord on the Security Deposit. Sublandlord shall not be required to keep the Security Deposit in
a segregated account, and the Security Deposit may be commingled with other funds of Sublandlord. 
 23. Entire Agreement,
Miscellaneous.

modification, termination or waiver is sought and unless the same is permitted under the terms and provisions of the Master Lease. 
 (c)
This Sublease shall have no binding force and effect and shall not confer any rights or impose any obligations upon either party unless and until both parties have executed it. Under no circumstances shall the submission of this Sublease in draft
form by or to either party be deemed to constitute an offer for the subleasing of the Subleased Premises. 
 (d) This Sublease and all the
obligations of Subtenant to pay Rental and perform all of its other covenants and agreements hereunder shall in no way be affected, impaired, delayed or excused because Sublandlord or Landlord are unable to fulfill any of their respective
obligations hereunder, either explicit or implicit, if Sublandlord or Landlord is prevented or delayed from so doing by reason of strikes or labor troubled by accident, adjustment of insurance or by any cause whatsoever reasonably beyond
Sublandlord’s or Landlord’s reasonable control 
 (e) Each and every right and remedy of Sublandlord under this Sublease shall be
cumulative and in addition to every other right and remedy herein contained or now or hereafter existing at law or in equity, by statute or otherwise.

provision of the Sublease. 

  
 19 








 4. Limitations. Nothing contained in this Agreement shall (a) be construed to modify,
waive, affect, release or discharge any of the provisions, covenants, or conditions in the Master Lease; or (b) be construed to enlarge or increase Landlord’s obligations or Tenant’s rights under the Master Lease or otherwise. 

5. Sublease Subordinate to Master Lease. The Sublease shall be subject and subordinate at all times to the Master Lease and all of its
provisions, covenants, and conditions. Subtenant acknowledges and agrees that all of Subtenant’s rights under the Sublease shall be subject to Landlord’s rights and reservations set forth herein and in the Master Lease. In case of any
conflict between the provisions of the Master Lease and the provisions of the Sublease, the provisions of the Master Lease shall govern. 

6. Subtenant’s Use of Sublease Premises. Subtenant shall observe, comply with, and perform all of those terms, conditions and
covenants in the Master Lease that are applicable to the use of the Sublease Premises. 
 7. No Privity of Contract; No Right to Exercise
Any Options. This Agreement does not create, and Subtenant does not have, any privity of contract, nor any other relationship with Landlord (other than the contractual relationship created by this Agreement). In no event shall Subtenant have the
right to exercise any options (including, without limitation, any extension, renewal, expansion, or purchase options), or any other elective rights (including, without limitation, any right of first offer and/or right of first refusal) that Tenant
may possess according to the terms of the Master Lease. 
 8. Amendment to Sublease. Tenant and Subtenant agree not to amend or
modify the terms of the Sublease (and, if entered into in violation of this covenant, such amendment or modification shall not be valid) without obtaining the prior written consent of Landlord thereto (and Landlord’s mortgagee), which approval
shall not be unreasonably withheld or delayed. 
 9. No Consent by Landlord to Any Work. Nothing herein contained shall be construed
as consent by Landlord to any proposed work to be performed in the Premises or Sublease Premises by either Tenant or Subtenant, or both of them. Any such work shall be subject to obtaining Landlord’s consent pursuant to the Master Lease and
shall be performed in compliance with the provisions of said Master Lease. Notwithstanding the foregoing, Landlord hereby approves the work outlined on Exhibit C of the Sublease, provided that Tenant shall be responsible to restore, at
Landlord’s election exercisable by giving written notice to Tenant on or before such date which is thirty (30) days prior to the Term Expiration Date of the Master Lease, any changes made to the communicating stair between floors five and
six of the Premises, on or before the Term Expiration Date of the Master Lease, all at Tenant’s sole cost and expense. 
 10. Breach
or Violation of Any Provision of the Master Lease. Any breach or violation of any provisions of the Master Lease by Subtenant shall be deemed to be and shall constitute a default by Tenant thereunder. 

11. Assignment/Subletting. This Agreement shall not relieve Tenant (or Subtenant) of the obligation to obtain Landlord’s consent
(and Landlord’s mortgagee’s consent) to any further assignment or subletting, all in accordance with the terms of the Master Lease. 

  
 20 








 12. Insurance. Subtenant shall name Landlord as an additional insured party under any
liability insurance policy which Subtenant is required to maintain under the Sublease with respect to the Sublease Premises, and Subtenant shall deliver to Landlord, and to Landlord’s mortgagee, a certificate of such insurance within thirty
(30) days after the execution of this Agreement. Nothing in this paragraph, however, shall relieve Tenant from its obligation to carry the full insurance required of its under the Master Lease. 

13. Indemnification. Each and every obligation of Subtenant to indemnify Tenant under the Sublease shall also extend to and be for the
benefit of Landlord. Additionally, all indemnities given by Tenant under the Master Lease are hereby deemed to be triggered not only by the acts or omissions of Tenant, its employees, agents, invitees, independent contractors, and other like
parties, but also, by the acts or omissions of Subtenant, its employees, agents, invitees, independent contractors, and other like parties. 

14. Landlord’s Subrogation to the Rights of Tenant. Tenant and Subtenant hereby agree that, if Subtenant should be in default of
any of Subtenant’s obligations under the Sublease, which default also constitutes a default by Tenant under the Master Lease, then Landlord shall be permitted after written notice to Tenant to avail itself of all of the rights and remedies
available to Tenant in connection therewith. Without limiting the generality of the foregoing, Landlord shall be permitted (by assignment of a cause of action or otherwise) to institute an action or proceeding against Subtenant in the name of Tenant
in order to enforce Tenant’s rights under the Sublease, and shall also be permitted to take all ancillary actions (e.g., serve default notices and demands) in the name of Tenant as Landlord shall reasonably determine to be necessary. Tenant
agrees to cooperate with Landlord, and to execute such documents as shall be reasonably necessary, in connection with the implementation of the foregoing rights of Landlord. Tenant and Subtenant expressly acknowledge and agree that the exercise by
Landlord of any of the foregoing rights and remedies: (a) shall not constitute an election of remedies, (ii) shall not in any way impair Landlord’s entitlement to pursue other rights and remedies directly against Tenant, and
(iii) shall not establish any privity of contract or any other relationship between Landlord and Subtenant, or in any way create a landlord/tenant relationship between Landlord and Subtenant. 

15. Termination of Master Lease. If the Master Lease shall be terminated for any reason, or Landlord shall accept a surrender of the
same, then, subject to the terms set forth in this paragraph 15, the Sublease and the term and estate thereby granted shall terminate upon written notice from Landlord to Subtenant, and Subtenant shall vacate the Sublease Premises on the effective
date of such termination or surrender. Notwithstanding anything to the contrary contained in the Master Lease or the Sublease, in the event of the termination of the Master Lease (including, without limitation, following rejection of the Master
Lease in any bankruptcy or similar proceeding or following Tenant’s exercise of its termination right pursuant to Exhibit N of the Master Lease) or Master Landlord’s reentry and repossession of the Premises prior to the expiration of the
Term, the Master Landlord shall serve upon Subtenant written notice that the Master Lease has been terminated together with a statement of any and all sums which would at that time be due under the Master Lease but for such termination, and of all
other defaults, if any, under the Master Lease. Subtenant shall thereupon have the option to obtain a reinstatement of the Master Lease in accordance with and upon the following terms and conditions: 

(a) Upon the written request of Subtenant, within thirty (30) days after receipt of such notice from Master Landlord that the Master
Lease has been terminated or Master Landlord has reentered and repossessed the Premises, the Master Landlord shall reinstate the Master Lease of the entire Premises with Subtenant, provided Subtenant cures any previously uncured defaults of
Sublandlord under the Master Lease beyond applicable notice and cure periods which are reasonably susceptible of cure by Subtenant prior to the reinstatement of the Master Lease, and reimburses Master Landlord for all of Master Landlord’s costs
and expenses arising from Sublandlord’s defaults under the Master Lease, including, without limitation, Master Landlord’s reasonable attorneys fees. 

  
 21 








 (b) Such reinstatement of the Master Lease shall be effective as of the date of termination of
the Master Lease, and shall be for the remainder of the Term (which shall include the right to exercise any applicable extension options subject to the terms and provisions of the Master Lease) and at the rent and upon all the agreements, terms,
covenants and conditions thereof. In addition to curing prior defaults of Sublandlord as provided in paragraph (a) above, such reinstatement shall require Subtenant to perform any unfulfilled obligations of Sublandlord under the Master Lease
first arising, or continuing, after the event of default which occasioned the termination of the Master Lease. Upon the execution of such reinstatement of the Master Lease, Subtenant shall expressly assume in writing all obligations as tenant under
the Master Lease from and after the date thereof, including, without limitation, the obligation to pay any and all sums thereafter arising under the Master Lease 

16. Landlord’s Legal and Other Costs. Tenant hereby acknowledges its obligation under the Master Lease to promptly reimburse
Landlord, as Additional Rent, for any administrative fee incurred by Landlord in connection with Landlord’s mortgagee reviewing and approving the Sublease and this Agreement, if applicable, not to exceed $500.00 as set forth in
Section 6.1.6 of the Lease. Landlord agrees not to charge a review fee in connection with its own reviewing of the Sublease and producing this Agreement. 

17. Landlord’s Share of Excess Rent. Tenant hereby acknowledges its obligation, pursuant to Section 6.1.6 of the Master
Lease, to pay to Landlord, immediately upon receipt thereof, 50% of the excess of the Rent Differential (as defined in the last paragraph of Section 6.1.6 of the Master Lease), if applicable. 

18. Miscellaneous. 
  

	 	a.	No Recording. Tenant and Subtenant each agrees not to record this Agreement. 

  

	 	b.	Entire Agreement. This Agreement contains the entire agreement between Landlord, Tenant and Subtenant with respect to its subject matter, and incorporates and supersedes all prior negotiations, discussions and
agreements between the parties. This Agreement may be amended only by subsequent written agreement between Landlord, Tenant and Subtenant. 


  
 22 









	 	c.	Brokers. Tenant and Subtenant each agree that any fees or commissions due to any broker or finder with regard to the Sublease Premises or the Sublease shall be paid by Tenant or Subtenant as they may agree.
Tenant and Subtenant agree to indemnify, defend (with counsel reasonably satisfactory to Landlord), and hold Landlord harmless from and against any loss, liability and expense (including, without limitation, reasonable attorneys’ fees and
disbursements) arising out of claims for fees or commissions with regard to the Sublease Premises or the Sublease. 

  

	 	d.	Construction. This Agreement shall be governed by, and construed in accordance with, the laws of the state in which the Property is located. Time is of the essence of each and every provision of this Agreement.
If any provision of this Agreement shall be held to be invalid or unenforceable to any extent, the remainder of this Agreement shall not be affected thereby and each provision of this Agreement shall be valid and enforceable to the fullest extent
permitted by law. 

  

	 	e.	Counterparts. This Agreement may be executed in one or more counterparts all of which when taken together will constitute a single agreement. All signatures need not appear on any one counterpart.


  

	 	f.	Effectiveness of Agreement. This Agreement is submitted to Tenant and Subtenant on the understanding that it will not be considered an offer and will not bind Landlord in any way until (a) Tenant and
Subtenant have duly executed and delivered duplicate originals hereof and of the Sublease to Landlord, (b) Landlord has executed and delivered one of such originals of this Agreement to Tenant and Subtenant, and (c) Landlord’s
mortgagee has executed and delivered one of such originals of this Agreement (specifically, the Consent of Mortgagee attached hereto and made a part hereof) to Landlord, whereupon Landlord shall deliver a fully-executed copy thereof to Assignor,
Tenant, and Subtenant. 

  

	 	g.	Binding on Successors and Assigns. This Agreement shall inure to the benefit of, and be binding upon, the parties hereto, and upon their respective successors and assigns; provided, however, that nothing in this
paragraph shall be interpreted to create any rights of assignment or transfer that do not already exist pursuant to the Master Lease and/or this Agreement.

improvements in the Premises. In connection therewith, Tenant agrees to furnish to Landlord a list of any “long lead” items that may affect the timely completion of the Premises, which such items shall include, for example, doors, aluminum
frames, chiller, vertical fan coils, generator, 600 amp switch, UPS, lights, carpet and any other item having a delivery time of four (4) or more weeks by July 10, 2008, Landlord and Tenant agreeing to finalize the “long lead”
items as soon as possible such that Landlord may release/award the same together with mechanical, electrical, plumbing and drywall subcontracts, by July 10, 2008. Other items shall be released/awarded once Landlord and Tenant have approved the
Tenant’s Plans as hereinafter provided, but in no event shall such other critical path items be awarded later than August 6, 2008. Landlord may, at its election, permit Tenant to review and provide input during the preparation of
Tenant’s Plans and may provide Tenant with preliminary plans and specifications as they are made available to Tenant. Upon receipt, Tenant shall have ten (10) days to comment upon the Tenant’s Plans and shall be deemed approved in the
event that Tenant fails to respond within such ten (10) day period. Landlord and Tenant shall use good faith, diligent efforts to agree on the Tenant’s Plans in a timely manner (i.e. by August 2, 2008). 

In reaching such agreement, Landlord and Tenant shall each approve portions of Tenant’s Plans that are acceptable and shall note their
respective objections to the portions that are unacceptable to each of them so as to enable Landlord to continue construction and order materials in a timely manner. In connection with Tenant’s review of the Tenant’s Plans, or if Tenant
fails to deliver comments to the Tenant’s Plans (or any modifications thereto), Landlord 

  
 - 6 - 








 
may require by prompt written notice to Tenant an adjustment in the Scheduled Term Commencement Date (such adjustment to be determined by Landlord in its reasonable judgment). Landlord’s
notice to Tenant shall include reasonable detail describing the cause of the adjustment and the resulting extension of time caused by Tenant’s delay (a “Tenant Plan Delay Day(s)”). Any such extension in time, whether mutually agreed
to by Landlord and Tenant or determined by their respective architects in the event of dispute pursuant to Section 3.5, shall result in Tenant’s Plan Delay Days as hereinbefore determined, in addition, Landlord will not approve
Tenant’s Plans (or changes to Tenant’s Plans) which involve any construction, alterations or additions requiring unusual expense to readapt the Premises to normal office use on the Term Expiration Date, unless Tenant first gives assurances
acceptable to Landlord that such readaptation shall be made prior to such termination without expense to Landlord. All revisions and modifications to the Tenant’s Plans shall be made promptly by Landlord and revised sets of Tenant’s Plans
shall be forthwith furnished to Tenant upon Landlord’s receipt thereof, Landlord hereby agreeing to inform Tenant during the plan approval process and, in any event, prior to the installation thereof, of any such items that may require unusual
expense to readapt the Premises as aforesaid. All revisions and modifications to the Tenant’s Plans shall be made promptly by Landlord and revised sets of Tenant’s Plans shall be forthwith furnished to Tenant upon Landlord’s receipt
thereof. Landlord and Tenant hereby further agree to acknowledge in writing when final approval by Landlord and Tenant of Tenant’s Plans has occurred. No changes or modifications to Tenant’s Plans being constructed by Landlord pursuant
thereto shall be made without Tenant’s consent, such consent not to be unreasonably withheld or delayed by Tenant. 
 Landlord shall
cause the Premises to be completed in accordance with Tenant’s Plans. After final approval of Tenant’s Plans by Landlord and Tenant, the Tenant may request changes to Tenant’s Work by altering, adding to, or deducting from
Tenant’s Work as set forth in the agreed form of Tenant’s Plans (each such requested change shall be submitted pursuant to the form of Change Order attached hereto as Exhibit “L” and shall be referred to herein as a “Change
Order”). A Change Order requested by Tenant in Tenant’s Work may also necessitate an adjustment in the Scheduled Term Commencement Date and may result in Tenant Alteration Delay Days (as hereinafter defined), in accordance with and subject
to the terms and conditions set forth below. Landlord shall notify Tenant in writing of the cost of the Change Order (and effect on the Cost of Tenant’s Work) and if such requested Change Order shall result in Tenant Alteration Delay Days, and
therefore an adjustment in the Scheduled Term Commencement Date. Tenant shall have three (3) business days to accept such Change Order (and the resulting cost and timing changes as set forth in Landlord’s notice) or to withdraw the
requested Change Order. Failure by Tenant to respond within such three (3) business days shall be deemed a rejection of the Change Order. In addition, Landlord agrees to provide Tenant, upon Tenant’s request, with sufficient itemization
and back-up documentation to facilitate analysis and to confirm the cost of any such changes in the Tenant’s Work initiated by Tenant. Tenant shall pay to Landlord an amount equal to the actual Cost of Change Orders less credits for any
Tenant’s Work deleted, in excess of an allowance (the “Allowance”) equal to $42.66/RSF, or $3,220,616.70 in total (the “Allowance”; hereinafter, collectively the “Cost of Tenant’s Work”). Included in all costs
shall be a contractor’s fee of six percent (6%). The Cost of Tenant’s Work shall be fully paid by Tenant (and/or credited against the Allowance, as applicable) within fourteen (14) business days of receipt of an invoice from Landlord
but after all of the Allowance has been exhausted by Tenant. In the event that Tenant does not fully utilize the Allowance, any remaining amount shall be credited against the Fixed Rent until all such amounts have been utilized. 

  
 - 7 - 








 In the event that Tenant requests a Change Order which would, due to materials or equipment
having long delivery times or due to resulting sequencing delays, and notwithstanding Landlord’s diligent efforts, result in a delay in the Scheduled Term Commencement Date, then Tenant shall be deemed to have agreed that it will pay Fixed Rent
(as hereinafter provided in Section 4.1) and additional rent hereunder for a number of days equal to the actual number of days (the “Tenant Alteration Delay Days”) as certified by Landlord and its architect, and agreed to by Tenant
and Tenant’s architect, by which the Scheduled Term Commencement Date would be delayed by such alterations or additions, giving due consideration to Landlord’s obligation to use diligent efforts to accelerate construction to make up for
lost time due to delays. Landlord agrees to promptly provide Tenant with written notice of such determination, such notice to include reasonable detail describing the cause of the delay and the number of Tenant Alteration Delay Days as certified by
Landlord and its architect. Should Tenant disagree with the calculation of Tenant Alteration Delay Days as hereinabove determined, then such disagreement shall be resolved pursuant to the provisions of Section 3.5 hereof. 

All Tenant improvements, changes and additions comprising the Tenant’s Work shall be part of the Premises and shall remain therein at the
end of the Term), except for Tenant’s business fixtures, equipment (including generators purchased out of the Allowance), furniture (including furniture purchased out of the Allowance) and personal property (which such personal property shall
include, without limitation, demountable partitions, equipment and telephone, security or computer systems), all of which fixtures, equipment, furniture and personal property shall remain the property of the Tenant and shall be removed at the
expiration of the Term; and such other items shall be removed or left as the Landlord and Tenant agree in writing at the tune of Landlord’s approval of the Tenant’s Plans as hereinafter provided. Tenant agrees to repair, at its sole cost
and expense, any damage to the Premises caused by any such removal by Tenant in accordance with this paragraph and Section 6.1.2 hereof. 
 Tenant
(including its contractors, agents or employees) shall have access to the Premises, four (4) weeks prior to the Scheduled Term Commencement Date applicable to each Phase of the Premises so as to prepare the Premises for occupancy by Tenant
(including for telephone/data, security and furniture installations), provided that (i) Tenant’s contractors, agents or employees work in a harmonious labor relationship with Landlord’s general contractor; (ii) reasonable prior
notice is given to Landlord specifying the work to be done, and (iii) no work, as reasonably determined by Landlord, shall be done or fixtures or equipment installed by Tenant in such manner as to materially interfere with the completion of the
work being done by or for Landlord in the Premises or the Building. During any such early access period, no Fixed Rent or additional rent or other charges shall accrue or be payable, but otherwise the performance of any such work by Tenant shall be
subject to all the terms, covenants and conditions contained in this Lease. 
 In connection with the initial construction and delivery of
the Premises to Tenant, Landlord agrees to provide Tenant with the following allowances, in addition to the Allowance: (i) up to $600,000 to be used for systems furniture or furnishings for Tenant’s network


  
 - 8 - 








 
operations center or training facility, which such furniture shall remain the property of Tenant, unless there is a continuing, uncured Event of Default (as defined in Section 9.1 of this
Lease) in which event such furniture shall automatically become the property of Landlord; (ii) up to $250,000 to be used to offset moving expenses; and (iii) up to $25,000 for building signage as hereinafter provided in
Section 6.1.20. Tenant shall furnish to Landlord reasonable back up documentation evidencing the foregoing prior to any payment by Landlord. The parties agree to execute a bill of sale to confirm furniture ownership, at the request of either
party. 
 Further, Landlord agrees to provide Tenant with the ability to amortize up to an additional $250,000 over the Term at a rate equal
to eight percent (8%) per annum to be used for telephone/data infrastructure. Tenant agrees to provide Landlord with reasonable back up documentation evidencing the foregoing prior to any payment by Landlord. The parties shall execute an
amendment to this Lease, in mutually agreeable form, evidencing any such amortization and resulting Rent changes. 
  

	3.2	PREPARATION OF PREMISES FOR OCCUPANCY 

 Landlord agrees to use reasonable good faith
efforts to have the Premises Ready for Occupancy (as hereinafter defined) on or before the Scheduled Term Commencement Date which such date shall, however, be extended for a period equal to that of any delays due to governmental regulations, unusual
scarcity of or inability to obtain labor or materials, labor difficulties, casualty or other causes reasonably beyond Landlord’s control (each, a “Force Majeure Delay”), or any Tenant Delay (as hereinafter defined). For purposes of
this Lease, a “Tenant Delay” shall mean any one of the following: (i) changes requested by Tenant to approved final plans for the Tenant’s Work; (ii) Tenant’s failure to supply information as reasonably requested by
Landlord in order to complete construction in a timely manner (e.g. the “long lead” items described in Section 3.1), (iii) Tenant’s failure to approve the Tenant’s Plans in a timely manner (e.g. Tenant Plan Delay Days),
(iv) Tenant Alteration Delay Days; or (v) a written request of Tenant to stop work. The Premises shall be deemed ready for occupancy (“Ready for Occupancy”) on the earlier of: 

 

	 	(a)	the date on which Tenant begins conducting business on any portion of the Premises; or 

  

	 	(b)	the date on which all of the following have occurred: (i) the Landlord’s Work is substantially completed in compliance with the approved final plans therefor as certified by Landlord’s architect, except
for punch list items relating to Tenant’s Work which do not interfere with Tenant’s use of the Premises for its operation and Landlord has obtained a Certificate of Occupancy (which may be temporary) for the Premises and has provided
Tenant with a copy thereof; provided, however, that if Landlord is unable to substantially complete construction by the Scheduled Term Commencement Date due to any Tenant Delay, then notwithstanding any language to the contrary set forth herein, the
Premises shall be deemed “Ready for Occupancy” on the date the Premises would have been substantially completed, but for a Tenant Delay, subject to Tenant’s right to dispute the same as hereinafter provided; and (ii) all
approvals and permits from the appropriate governmental authorities required for the legal occupancy of the Premises have been obtained. 


  
 - 9 - 








 If the Premises are not deemed Ready for Occupancy on or before the Outside Delivery Date (as
defined below) for whatever reason, Tenant may (i) cancel this Lease at any time thereafter while the Premises are not deemed ready for occupancy by giving notice to Landlord of such cancellation which shall be effective ten (10) days
after such notice, unless within such ten (10) day period Landlord delivers the Premises ready for occupancy as defined herein, in which event such notice of cancellation shall be rendered null and void and of no further force or effect, or
(ii) to enforce Landlord’s covenants to construct the Premises in accordance with the terms of this Lease. In the event Tenant elects to enforce Landlord’s agreement to construct the Premises in accordance with this Lease, Tenant
shall also have the right to terminate this Lease if Landlord fails to complete the Premises within the period of time set by any court of competent jurisdiction for such work to be completed, or within such additional period of time from the date
of Landlord’s default as may be mutually agreed to by Landlord and Tenant. The foregoing rights shall be the Tenant’s sole remedy at law or in equity for Landlord’s failure to have the Premises ready for occupancy as required
hereunder. 
 For purposes hereof, the Outside Delivery Date shall be deemed to refer to that certain date which is sixty (60) days
following the Scheduled Term Commencement Date, as such date may be extended for a period equal to that of (i) any delays due to a Force Majeure, or (ii) the number of delay days caused by a Tenant Delay. 

Landlord and Tenant agree to resolve any disputes under this Article 3 pursuant to the provisions of Article 3.5 hereof, unless the parties
agree otherwise. 
  

	3.3	GENERAL PROVISIONS APPLICABLE TO CONSTRUCTION 

 All construction work required or
permitted by this Lease, whether by Landlord or by Tenant, shall be done in a good and workmanlike manner and in compliance with all applicable laws and all lawful ordinances, regulations and orders of governmental authorities (hereafter
collectively referred to as the “Codes”), and the requirements of all insurers of the Building. Further, Landlord agrees to ensure that, as of the Scheduled Term Commencement Date, all base building systems (i.e., HVAC, plumbing,
electrical, elevators, etc.) shall be in good order and repair. Either party may inspect the work of the other at reasonable times and shall promptly give written notice of observed defects, provided that any inspection or right to inspect is solely
for the benefit of the party having such right, and shall not constitute a representation or warranty to the other party or create any liability with respect to the party performing the inspection or having such right. Landlord’s obligations
under Section 3.1 shall be deemed to have been performed when the Premises are deemed Ready for Occupancy except for items which are incomplete or do not conform with the requirements of Section 3.1 and as to which Tenant shall, in either
case, provide written notice to Landlord on or around the date when the Premises are deemed Ready for Occupancy. If Tenant does not occupy the Premises for the Permitted Uses within thirty (30) days after they are deemed Ready for Occupancy as
provided in Section 3.2, a certificate of completion by a licensed architect or registered engineer shall be conclusive evidence that Landlord has performed all such obligations except for items stated in such certificate to be incomplete or
not in conformity with such requirements.

	3.4	REPRESENTATIVES 

 Each party authorizes the other to rely in connection with their
respective rights and obligations under this Article 3 upon approval and other actions on the party’s behalf by Landlord’s Representative(s) in the case of Landlord or Tenant’s Representative in the case of Tenant or by any person
designated in substitution or addition by notice to the party relying. 
  

	3.5	ARBITRATION BY ARCHITECTS 

 Whenever there is a disagreement between the parties with
respect to construction by Landlord of Tenant’s Work, such disagreement shall be definitively determined by the following procedure: Each of Landlord and Tenant shall appoint one (1) architect, such two (2) architects will then
(within five (5) business days of their appointment) appoint a third architect licensed in the Commonwealth of Massachusetts with not less than ten (10) years experience. Each architect shall establish within ten (10) days of their
appointment the matter in dispute. In case of any dispute with respect to dollar amounts or lengths of time or dates such as the date of Substantial Completion, the dollar amount or length of time or date shall be the average of the two
(2) closest determinations by the three (3) architects, with the determination of the architect which was not closest to another architects’ determination excluded from such calculation. In case of any dispute not involving dollar
amounts or lengths of time or dates (i.e. the approval of plans) the determination by at least two (2) of the three (3) architects shall be required in order to resolve the matter in dispute. Landlord and Tenant shall each bear the cost of
the architect selected by them respectively and shall share equally the cost of the third architect. During such arbitration period, the parties agree to cooperate with one another so as to proceed with construction and with their respective
obligations hereunder in a timely manner. Each determination under this Section 3.5 shall be binding upon Landlord and Tenant. 
  

	3.6	WARRANTY OF TENANT’S WORK 

 Notwithstanding anything to the contrary contained in
this Lease, Landlord hereby warrants and guarantees that the Tenant’s Work shall be free from defects in workmanship and materials for a period of one (1) year after the Commencement Date. Upon expiration of said one (1) year period,
Landlord shall assign to Tenant any and all warranties and guarantees with respect to Tenant’s Work and, to the extent that any such warranties and guarantees are not assignable, Landlord agrees to enforce the same for the benefit of Tenant, at
Tenant’s sole cost and expense. Tenant shall not be responsible to pay for any such warranties of less than one (1) year duration or enforcement by Landlord against its own employees or against Gutierrez Construction Co., Inc., or against
any of its other affiliates (including their respective employees). Landlord agrees to repair, at its sole cost and expense, any latent defects in Landlord’s Work promptly after receipt of notice therefrom from Tenant, provided that such notice
from Tenant is received by Landlord within three (3) years from their discovery by Tenant. In connection therewith, Tenant shall notify Landlord promptly after it becomes aware of any such latent defects. Any repairs or replacements or
alterations to Tenant’s Work (other than latent defects) after said initial one (1) year period shall be chargeable to Tenant in accordance with and subject to the provisions of Section 4.2 hereof.

	4.1	RENT 

 Tenant agrees to pay, without any offset or reduction whatever, Fixed Rent equal
to l/12th of the annual Fixed Rent set forth in Section 1.1 hereof in equal installments in advance on the first day of each calendar month included in the Term; and for any portion of a calendar month at the beginning or end of the Term, at
the rate payable for such portion in advance. The term “Rent” shall at all times be used herein to mean Fixed Rent plus additional rent or other sums of money payable under this Lease (including, without limitation, Section 4.2 hereof

 Notwithstanding the foregoing, Landlord and Tenant agree
that so long as there is not then an uncured, continuing material Event of Default hereunder, Landlord shall abate the monthly Fixed Rent from and after the Commencement Date through the following dates: Phase 1 shall be abated for two full months
(January 1, 2009, assuming that the Scheduled Term Commencement Date occurs on November 1, 2008 and is not delayed due to Building construction issues not caused by Tenant) and Phase 2 shall be abated until September 1, 2009. If Tenant at
any time during such period is in material default under this Lease beyond any applicable notice and cure periods, Tenant shall immediately pay to Landlord all sums previously abated hereunder and such abatement shall automatically cease. Tenant
shall be responsible for any electricity and any other services consumed in the Premises during such tune not comprising “Fixed Rent” hereunder. 
  

	4.2	OPERATING COST ESCALATION 

 With respect to the First Fiscal Year for Tenant’s
Paying Operating Cost Escalation, or fraction thereof, and any Fiscal Year or fraction thereafter, Tenant shall pay to Landlord, as additional rent, Tenant’s share of the Operating Cost Escalation (as defined below), if any, on or before, the
thirtieth (30th) day following receipt by Tenant of Landlord’s Statement (as defined below). As soon as practicable after the end of each Fiscal Year ending during the Term and after
Lease termination, Landlord shall render a statement (“Landlord’s Statement”) in reasonable detail and according to usual accounting practices certified by Landlord and showing for the preceding Fiscal Year or fraction thereof, as the
case may be, Landlord’s Operating Costs, 
 EXCLUDING the principal, interest and amortization on mortgages for the Building, and Lot
or leasehold interests therein, depreciation, improvements made to the Building, the Lot or the Park that do not lower operating costs, and the cost of special services rendered to tenants (including Tenant) for which a special charge is made,

of operating, maintaining and repairing the common areas and facilities within the Park (such as, but not limited to, snow plowing, sanding, sand removal, lot sweeping, landscaping, common area and street lighting, and management); and all
other reasonable and necessary expenses paid in connection with the operation, cleaning, maintenance, and repair of the Building and Lot, or either, and properly chargeable against income. If Landlord (i) installs a new or replacement capital
item for the purposes of (i) reducing Landlord’s Operating Costs, or (ii) is required to perform capital repairs or replacements or to install capital items in order to comply with changes in applicable law from and after the
Commencement Date, or (iii) or is required pursuant to Section 5.1.3 to perform capital repairs or replacements which are chargeable to Tenant to the extent provided by the provisions of this Section, the costs thereof as reasonably
amortized by Landlord over their useful life in accordance with generally accepted accounting principles, with legal interest (not to exceed the then “Prime Rate” published in the Wall Street Journal plus two percent (2%) per annum)
(“Agreed Interest Rate”) on the unamortized amount, shall be included in “Landlord’s Operating Costs”. In such event, Tenant shall pay Tenant’s share of such amortization payment for each month after such improvement is
completed until the first to occur of the expiration of the Term or the end of the term over which such costs are required to be amortized. Landlord agrees that all of such services to be included in Landlord’s Operating Costs shall be obtained

any obligation to pay any Operating Cost Escalation on account of) the following: 
  

	 	(a)	Costs, expenses and fees relating to solicitation of, advertising for and entering into leases and other occupancy arrangements for space in the Park, including but not limited to legal fees, space planners’ fees,

	 	(g)	Any bad debt loss, rent loss or reserves for bad debts or rent loss. 

  

	 	(h)	The salary and indirect compensation (including, without limitation, all fringe benefits, workmen’s compensation, insurance premiums and payroll taxes) of any employee above the trade of property manager, and the

	 	(n)	The costs of repairs, alterations and general maintenance necessitated by the negligence or willful misconduct of Landlord or its agents, employees, or contractors or repairs, alterations, and general maintenance

	 	(r)	Costs incurred to maintain the structural integrity of the Building, except in the event caused by the Tenant as set forth in Section 5.1.3 hereof. 


In case of services which are not rendered to all areas of the Building on a comparable basis, the proportion allocable to the Premises shall
be the same proportion which the Rentable Floor Area of Tenant’s Space bears to the total rentable floor area to which such service is so rendered (such latter to be determined in the same manner as the Total Rentable Floor Area of the
Building), or shall be re-allocated by Landlord on a reasonable basis taking into consideration such factors as usage of a particular tenant in the Park and/or such other pertinent factors as reasonably determined by Landlord. Tenant shall be
responsible to pay its share of Landlord’s Operating Costs for the Building based upon the proportion that the Rentable Floor Area of Tenant’s Space bears to the Total Rentable Floor Area of the Building (i.e. 41.55%). Tenant shall also be
responsible to pay its pro rata share of Park-related costs, which shall be allocated by Landlord in a commercially reasonable mariner based upon the following: upon the ratio of the square footage of the Premises to the aggregate square footage of
all completed buildings in the Park (e.g. 460,588 RSF), as such buildings are completed from time to time (i.e. the Building’s current share of Park-related costs is approximately 39.45%). As of this date, the Park consists of approximately
460,588 RSF, specifically consisting of the following: 
  

			
	One Wall Street:	  	192,000 RSF
	Two and Ten Wall Street (Retail):	  	34,908 RSF
	Twenty Wall Street:	  	52,000 RSF
	Five Wall Street:	  	181,680 RSF
		
	Total: 460,588 RSF	  	


  
 - 15 - 








 “Operating Cost Escalation” shall be equal to the difference, if any, between: 

 

	 	(s)	the product of Landlord’s Operating Costs per rentable square foot as indicated in Landlord’s Statement times the Rentable Floor Area of Tenant’s Space; and 


 

	 	(t)	the product of the Annual Estimated Operating Costs (as reduced pursuant to this Section 4.2) per rentable square foot times the Rentable Floor Area of Tenant’s Space. 


If, with respect to any Fiscal Year or fraction thereof during the Term, Tenant is obligated to pay Operating Cost Escalation, then Tenant
shall pay, as additional rent, on the first day of each month of each ensuing Fiscal Year thereafter, until Landlord’s Statement for an ensuing Fiscal Year reflects that Tenant is not obligated to pay Operating Cost Escalation, “Estimated
Monthly Escalation Payments” equal to l/12th of the annualized Operating Cost Escalation for the immediately preceding Fiscal Year. Estimated Monthly Escalation Payments for each ensuing Fiscal Year shall be made retroactively from the first
day of such Fiscal Year and on account of the payment to be made pursuant to the first sentence of this Section 4.2 for such Fiscal Year, with an appropriate additional payment or refund to be made at the time such payment is due for the
previous year, 
 The term “Fiscal Year” as used in this Article shall mean the period of twelve (12) consecutive months
commencing on January 1st and ending on December 31st. 

The term “real estate taxes” as used above shall mean all taxes of every kind and nature assessed by any governmental authority on
the Lot, the Building and improvements, or both, and in the common areas of the Park, which the Landlord shall become obligated to pay because of or in connection with the ownership, leasing and operation of the Lot, the Building and improvements,
or both, and the Park, subject to the following: there shall be excluded for such taxes all income taxes, excess profits taxes, excise taxes, franchise taxes, gift, estate, succession, inheritance and transfer taxes, provided, however, that if at
any time during the Term the present system of ad valorem taxation of real property shall be changed so that in lieu of the whole or any part of the ad valorem tax on real property, there shall be assessed on Landlord a capital levy or other tax on
the gross rents received with respect to the Lot, Building and improvements, or both, a federal, state, county, municipal, or other local income, franchise, excise or similar tax, assessment, levy or charge (distinct from any now in effect) measured
by or based, in whole or in 

  
 - 16 - 








 
part, upon any such gross rents, then any and all of such taxes, assessments, levies or charges, to the extent so measured or based, shall be deemed to be included within the term “real
estate taxes”. 
 If the total of the monthly payments paid by Tenant with respect to any Fiscal Year exceeds the actual Operating Cost
Escalation for such Fiscal Year, then, such excess shall be refunded by Landlord to Tenant no later than thirty (30) days after the end of the Fiscal Year in question, unless the Term shall expire on or prior to said 120-day period, in which
event Landlord shall refund such excess on the last day of the Term. 
 Tenant shall have the right, but not the obligation, to contest (or
request that Landlord so contest on behalf of all tenants of the Building) in good faith by appropriate proceedings diligently pursued the imposition or amount of any real estate taxes assessed against the Lot or the Building or such personal
property taxes payable by it hereunder, including the right on behalf of, and in the name of the Landlord, to seek abatements thereto. The Landlord shall reasonably cooperate with Tenant, at Tenant’s sole expense, in any such contest or
abatement proceedings. In the event that Tenant determines not to contest such taxes and Landlord desires to file such contest (or Tenant requests that Landlord file such contest), Landlord shall give written notice of that fact to all affected
tenants, including Tenant, and shall have the sole right as to such tax bill to contest in good faith by appropriate proceedings diligently pursued the imposition or amount of any real estate taxes assessed against the Lot or the Building or such
other taxes payable by Tenant hereunder, including the right to seek abatements thereto. In such event, the Tenant shall reasonably cooperate with Landlord, at no cost to Tenant, in any such contest or abatement proceedings. Landlord shall also
reasonably cooperate and assist Tenant, at no cost to Landlord, in procuring any applicable tax credits or incentives. 
 If Landlord shall
receive on behalf of the Lot or the Building a rebate or abatement on any tax with respect to which a payment is made by Tenant, then after deducting therefrom any costs reasonably incurred by Landlord in obtaining such rebate or abatement, all of
such net rebate or abatement relating to the Lot or the Building shall be returned to Tenant to the extent that such rebate or abatement relates to payment made by the Tenant and not reimbursed by Landlord. If Tenant shall receive on behalf of the
Lot or the Building a rebate or abatement on any tax with respect to which a payment is made by Tenant, then after deducting therefrom any costs reasonably incurred by Tenant in obtaining such rebate or abatement, all of such net rebate or abatement
related to the Lot, the Building or to personal property taxes assessed against the Tenant’s property shall be retained by Tenant, as its sole property, to the extent such rebate or abatement relates to a payment made by Tenant and not
reimbursed by Landlord. The remaining portion of such net rebate or abatement shall promptly be returned to Landlord. 
 In the event that
Landlord receives a refund on account of real estate taxes after the expiration of the Term, which refund relates to a Fiscal Year during the Term, the amount of such refund fairly allocable to Tenant shall be refunded to Tenant by Landlord within
thirty (30) days of its receipt of such refund. All references to real estate taxes “for” a particular Fiscal Year shall be deemed to refer to real estate taxes due and payable during such Fiscal Year without regard to when such
impositions are assessed or levied.

 All records pertaining to Landlord’s Operating Costs hereunder shall be maintained by the
Landlord for a period of three (3) years following the expiration of the Fiscal Year to which such records relate. Tenant shall have the right, through its representatives, to examine, copy and audit such records at reasonable times, but no
more than once per Fiscal Year, upon not less than thirty (30) days prior written notice to Landlord given within one hundred and twenty (120) days of receipt of Landlord’s Statement, otherwise Tenant’s right to dispute such
charges shall be waived. Such records shall be maintained at Landlord’s Address set forth in Section 1.1, or such other place within the Commonwealth of Massachusetts as Landlord shall designate from time to time for the keeping of such
records. The costs of such audits shall be borne by Tenant; provided, however, that if such audit establishes that the actual Operating Cost Escalation for the Fiscal Year in question is less than the Landlord’s final determination of the
Operating Cost Escalation as set forth in the Landlord’s Statement submitted to Tenant by at least five percent (5%) (and so long as the discrepancy amount exceeds $10,000.00), then Landlord shall pay the reasonable cost of such audit. If,
as a result of such audit, it is determined that Tenant must pay additional amounts to Landlord on account of the Operating Cost Escalation, or that Tenant has overpaid Landlord on account of the Operating Cost Escalation, then the undercharged or
overpaid party shall reimburse the other party for the payment due within thirty (30) days of the final determination. 

Notwithstanding anything contained in this Lease to the contrary, the responsibility for the payment of all real estate taxes with respect to
the Building and the Park shall be upon the Landlord and the Landlord agrees to pay the same as required by law. Landlord shall provide Tenant with copies of all tax bills and a computation of Tenant’s pro rata share thereof, as aforesaid. In
the event that any special assessments are assessed and payable, Tenant’s pro rata share of the same shall be calculated as if such assessments were being paid by Landlord over the longest period of time permitted by applicable law. 

Landlord shall have the right from time to time to change the periods of accounting under this Section 4.2 to any annual period other
than the Fiscal Year and upon any such change all items referred to in this Section shall be appropriately apportioned. In all Landlord’s Statements, rendered under this Section, amounts for periods partially within and partially without the
accounting periods shall be appropriately apportioned, and any items which are not determinable at the time of a Landlord’s Statement shall be included therein on the basis of Landlord’s best good faith estimate, and with respect thereto
Landlord shall render promptly after determination a supplemental Landlord’s Statement, and appropriate adjustment shall be made according thereto. All Landlord’s Statements shall be prepared on an accrual basis of accounting. 

Notwithstanding any other provision of this Section 4.2, if the Term expires or is terminated as of a date other than the last day of a
Fiscal Year at the end of the Term, Tenant’s last payment to Landlord under this Section 4.2 shall be made on the basis of Landlord’s best good faith estimate of the items otherwise includable in Landlord’s Statement and shall be
made on or before the later of (a) twenty (20) business days after Landlord delivers such estimate to Tenant, or (b) the last day of the Term, with an appropriate payment or refund to be made upon submission of Landlord’s
Statement, Without limitation, the obligation of Tenant to pay the Operating Cost Escalation with respect to any Fiscal Year during the Term (or portion thereof) or the Landlord’s obligation to make a refund therefore, as applicable, shall
survive the expiration or earlier termination of the Term.

	4.3	PAYMENTS 

 All payments of Fixed Rent and additional rent shall be made to Managing
Agent, or to such other person as Landlord may from time to time designate by written notice to Tenant. If any installment of rent, fixed or additional, or on account of leasehold improvements is paid after the due date thereof, at Landlord’s
election, it shall bear interest at the Agreed Interest Rate from such due date, which interest shall be immediately due and payable as further additional rent; provided, however, Landlord hereby acknowledges and agrees that Tenant shall have two
(2) grace periods of an additional five (5) days per each calendar year of the Term before which such interest shall be charged by Landlord.

the Premises in anything less than suitable, tenantable and usable condition, considering the nature of the Premises and the use reasonably made thereof, or in less than good and tenantable repair; for avoidance of doubt, Landlord acknowledges that
the original buildout of the Premises shall not be deemed improvements that must be removed by Tenant at the end of the Term; 
 6.1.3

safety appliances required by law or ordinance or any other regulation of any public authority because of any particular manner of use made by Tenant other than Tenant’s Permitted Use and to procure all licenses and permits so required because

pursuant to the provisions of this Section 6.1.5, and provided the enforcement of such requirement or law is stayed during such contest and such contest will not subject the Landlord to penalty or jeopardize the title to the Premises or
otherwise affect the Premises in any adverse way. Landlord shall cooperate with Tenant in such contest and shall execute any documents reasonably required in the furtherance of such purpose. Notwithstanding the foregoing, or any other contrary
provision set forth in tins Lease, Tenant shall not be required to construct or pay the cost of complying with any private restrictions, laws or insurance underwriter’s requirements requiring construction of improvements to the Premises or to
any other portion of the Building, unless such compliance is necessitated solely because of Tenant’s particular and unique use of the Premises or any alterations to the Premises made by or for Tenant; 

6.1.6 Assignment and Subletting -Tenant shall have the right, subject to the requirement of obtaining Landlord’s prior written
consent, such consent not to be unreasonably withheld, conditioned or delayed by Landlord, to assign this Lease or sublet the whole or any portion of the Premises, which assignment or sublease shall be only for the Permitted Uses, it being
understood that Tenant shall, as additional rent, reimburse Landlord promptly for reasonable legal and other expenses incurred by Landlord (or its mortgagee) (not to exceed $500.00 per request) in connection with any request by Tenant for consent to
assignment or subletting. No assignment or subletting shall affect the continuing primary liability of Tenant (which, following assignment, shall be joint and several with the assignee). Such consent by Landlord to any of the foregoing in a specific
instance (i) shall be reasonable, subject to the provision hereinafter provided, and (ii) shall be subject to the prior written approval of Landlord’s mortgagee(s) (except as hereinafter provided with respect to a Permitted
Transferee). Landlord’s consent shall not be treated as having been withheld unreasonably if, in connection with any such proposed assignment or subletting: (i) the terms of the proposed assignment or subletting do not prohibit further
assignments of the Lease or subletting of the Premises without the written consent of Landlord, the granting of winch consent shall be subject to the terms and conditions hereof, and in any event shall not be unreasonably withheld, conditioned or
delayed; and (ii) in connection with an assignment of this Lease, the assignee does not agree directly with Landlord, by written instrument in form reasonably satisfactory to Landlord, to be bound by all the obligations of Tenant hereunder
including, without limitation, the covenant against further assignment and subletting without the written consent of Landlord, subject to the terms and conditions of this Section. Tenant hereby acknowledges and agrees that the foregoing is not
intended to be an exclusive list of the reasons for which Landlord may reasonably withhold consent to a proposed request by Tenant for consent to assignment or subletting. No consent to any of the foregoing in a specific instance shall operate as
waiver in any subsequent instance. If an assignment or 

  
 - 24 - 








 
subletting is proposed to be made and Landlord’s consent is required as hereinabove provided, Tenant shall give Landlord prior notice of such proposal, which such notice shall include such
information (including creditworthiness information) as Landlord may reasonably request relative to facts which would bear upon the factors entering into the determination whether Landlord’s approval is to be granted. 

Notwithstanding any provision contained in this Lease to the contrary, no consent of Landlord (or Landlord’s mortgagee) shall be required
for the assignment of this Lease or the subletting of any portion (or the whole) of the Premises, (i) to a subsidiary of Tenant, (ii) to a corporation or other entity into or with which Tenant has merged, been reorganized or been
consolidated or to which substantially all of Tenant’s stock or assets are transferred, (iii) to any corporation or other entity which controls, is controlled by, or is under common control with Tenant, or (iv) to any corporation or
other entity with winch Tenant is otherwise affiliated (all of the foregoing hereinafter sometimes collectively shall be referred to as “Permitted Transfers”, and any person to whom any Permitted Transfer is made hereinafter sometimes
shall be referred to as a “Permitted Transferee”). In any event, the following conditions shall apply: (x) the Guaranty attached hereto in Exhibit “O” of this Lease (which shall be provided to Landlord simultaneously with
the execution of this Lease) shall remain in place; and (y) such Permitted Transferee agrees directly with Landlord by written instalment to be bound by all of the obligations of Tenant; in the event of any such assignment or subletting for
which no consent by Landlord is required hereunder, Tenant shall not be obligated to share Rent Differential as hereinafter set forth. For purposes of this Lease, and if applicable, a transfer or issuance of Tenant’s stock over the New York
Stock Exchange, the American Stock Exchange, any other public exchange or NASDAQ shall not be deemed an assignment, subletting or other transfer of this Lease or the Premises requiring Landlord’s consent. 

If this Lease shall be assigned, or if the Premises or any part hereof shall be sublet or occupied by any person other than Tenant, Landlord
may, at any time and from time to time, following an uncured, continuing Event of Default, collect rent (or any amounts due to Landlord hereunder) from the assignee, subtenant or occupant and apply the net amount collected to the annual Fixed Rent,
additional rent and all other charges herein reserved, but no such assignment, subletting, occupancy or collection shall be deemed a waiver of the provisions of this Section 6.1.6, or acceptance of the assignee, subtenant or occupant as tenant,
or a release of Tenant from the further performance of the terms, covenants and conditions of this Lease on the part of Tenant to be performed. In such event, after deducting Landlord’s share of the Rent Differential, equitably determined on a
monthly basis, if applicable as hereinafter provided, Landlord agrees to remit to Tenant any excess on a month to month basis. 
 If
Landlord’s approval of a sublease or assignment is necessary and Landlord approves a sublease or assignment, and said sublease or assignment is for a total rental amount which on an annualized basis is greater than the Fixed Rent and additional
rent due from Tenant to Landlord under this Lease, Tenant shall pay to Landlord, forthwith upon Tenant’s receipt of each installment of such excess rent, during the term of any approved sublease or assignment, as additional rent hereunder, in
addition to the Fixed Rent and other payments due under this Lease, an amount equal to fifty percent (50%) of the positive excess between all Fixed Rent and additional rent received by Tenant under the sublease or assignment and the Fixed Rent
and the 

  
 - 25 - 








 
additional rent due hereunder after Tenant has recouped, in full, its reasonable out-of-pocket expenses with respect to such sublease or assignment, including without limitation, reasonable real
estate brokerage commissions, utilities expenses, reasonable legal fees, reasonable free rent, reasonable marketing costs and the reasonable costs of refurbishment of the Premises for such sublease or assignment (the “Rent Differential”).
The Rent Differential shall not include the sales or rental proceeds received by Tenant in connection with the sale or lease of its personal property to a proposed transferee. In the event the sublease is for less than the full Premises hereunder,
the rent payable by Tenant shall be proportionately adjusted in determining the excess (but all expenses to be recouped will be deducted) pro rated on a square foot basis. Anything contained in the foregoing provisions of this section to the
contrary notwithstanding, neither Tenant nor any other person having interest in the possession, use, occupancy or utilization of the Premises shall enter into any lease, sublease, license, concession or other agreement for use, occupancy or
utilization of space in the Premises which provides for rental or other payment for such use, occupancy or utilization based, in whole or primarily on the net income or profits derived by any person from the Premises leased, used, occupied or
utilized (other than an amount based on a fixed percentage or percentages of receipts or sales), and any such purported lease, sublease, license, concession or other agreement shall be absolutely void and ineffective as a conveyance of any right or
interest in the possession use, occupancy or utilization of any part of the Premises; 
 6.1.7 Indemnity - To defend, with counsel
reasonably acceptable to Landlord, save harmless, and indemnify Landlord from any liability for injury, loss, accident or damage to any person or property occurring on the Premises, in the Building or the Lot, or elsewhere in the Park, and from any
claims, actions, proceedings and expenses and costs in connection therewith (including, without implied limitation, reasonable counsel fees): (i) to the extent arising from the negligent acts, omissions and/or willful misconduct of Tenant or
any of Tenant’s employees, agents, contractors, subtenants, assignees, licensees or invitees, not caused by the negligent acts, omissions and/or willful acts of Landlord, its agents, employees, contractors or invitees or (ii) resulting
from the failure of Tenant to perform and discharge its covenants and obligations under this Lease. In no event shall Tenant be obligated to indemnify Landlord for any willful or negligent act or omission of Landlord or of any of Landlord’s
employees, agents, contractors or licensees. The covenants and indemnifications set forth in this Section 6.1.7 shall survive the expiration or earlier termination of this Lease; 

6.1.8 Tenant’s Liability Insurance - To maintain public liability insurance in the Premises in amounts which shall, at the
beginning of the Term, be at least equal to the limits set forth in Section 1.1 and, not more than two times during the Term, shall be for such higher limits, if any, as are customarily carried in the area in which the Premises are located on
property similar to the Premises and used for similar purposes and to furnish Landlord (and/or its mortgagees) with the certificates thereof, prior to occupancy hereunder, evidencing such coverage and providing that the insurance indicated therein
shall not be cancelled without at least ten (10) days’ prior written notice to Landlord. Landlord and its mortgagee shall be named as additional insureds on any such policies;

interfere with Tenant’s daily operations and shall comply with Tenant’s reasonable security procedures, and Tenant shall have the right to have an employee accompany Landlord and/or its agents at all times that Landlord and/or its agents
are present on the Premises;

against Tenant or by or against any parties in possession of the Premises or any part thereof claiming under Tenant, to pay, as additional rent, all costs including, without implied limitation, reasonable counsel fees incurred by or imposed upon

by law;

 6.1.15 Changes or Additions - Except in connection with the construction of Tenant’s
Work hereunder, not to make any material changes or additions to the Premises without Landlord’s prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed. Notwithstanding the foregoing, Tenant may, from
time to time, at its own cost and expense and without the consent of Landlord, make non-structural alterations, additions or improvements to the Premises that are decorative in nature, so long as they do not affect any of the mechanical, electrical
or plumbing systems or life safety systems of the Building (collectively herein called “Alterations”) whose cost in any one instance is Thirty-Five Thousand Dollars ($35,000.00) or less, provided that Tenant first notifies Landlord in
writing of any such Alterations. If Tenant desires to make any Alterations costing in excess of Thirty-Five Thousand Dollars ($35,000.00) in any one instance or any other alteration, including any structural alteration or alteration affecting any of
the mechanical, electrical or plumbing systems of the Building, Tenant must first obtain the consent of Landlord thereto, which consent shall not be unreasonably withheld, conditioned or delayed. If Landlord reasonably concludes that the Alterations
involve any construction, alterations or additions requiring unusual expense to readapt the Premises to normal office use on the Term Expiration Date, Landlord shall notify Tenant in writing at the time of approval that such re-adaptation will be
required to be made by Tenant prior to such Term Expiration Date without expense to Landlord. Landlord shall not unreasonably require removal in the event an Alteration is substantially similar (functionally and quality wise) of the item so being
replaced. 
 Any and all alterations, including but not limited to the Alterations, shall be performed by GCCI at cost plus a profit equal
to six percent (6%), unless Landlord elects not to so perform the same in which event such Alterations shall be done by any contractor chosen by Tenant provided any such contractor is reputable, bondable by reputable bonding companies, carries the
kind of insurance and in the amounts set forth herein, and will work in harmony with Landlord’s contractors and laborers in the Building. Notwithstanding the foregoing, no such bonding is required for interior, non-structural, non-roof,
non-mechanical Alterations. 
 Tenant in making any alterations, including Alterations if applicable (i.e. GCCI does not elect to perform
the same as aforesaid), shall cause all work to be done in a good and workmanlike manner using all new materials substantially equal to or better than those used in the construction of the Premises and shall comply with or cause compliance with all
laws and with any direction given by any public officer pursuant to law and GCCI’s standard consistent with other similarly situated Class A buildings in the area in which the Building is located. Tenant shall obtain or cause to be
obtained and maintain in effect, as necessary, all building permits, licenses, temporary and permanent certificates of occupancy and other governmental approvals which may be required in connection with the making of the alterations, including the
Alterations. Landlord shall cooperate with Tenant in the obtaining thereof and shall execute any documents reasonably required in furtherance of such purpose, provided any such cooperation shall be without expense and/or liability to Landlord,
unless Landlord elects to have GCCI perform the same in which event it agrees to cause GCCI to comply with the foregoing provisions, including the obligation of GCCI to use all new materials in connection with any construction hereunder, and other
provisions set forth herein applicable to Tenant’s contractor. 

  
 - 28 - 








 At least annually if such Alterations or any other alterations hereunder have occurred during the
past calendar year, Tenant shall furnish to Landlord as-built sepias and, if applicable, operating manuals, or, at Landlord’s option and only if Tenant’s computer system is compatible with that of Landlord’s, computer disk
specifications compatible with Landlord’s computer system of the work done by Tenant during such past year and copies of all permits issued in connection therewith. 

Tenant shall have its contractor procure and maintain in effect during the term of such alterations, including Alterations, reasonably
satisfactory insurance coverages with an insurance company or companies authorized to do business in the Commonwealth of Massachusetts, and shall, upon Landlord’s request, furnish Landlord with certificates thereof; 

6.1.16 Holdover - To pay to Landlord an amount equal to one hundred and fifty percent (150%) of the Fixed Rent and additional rent
then applicable for the first thirty (30) days of holdover by Tenant and thereafter twice (i.e. 200%) the Fixed Rent and additional rent then applicable for each month or portion thereof if Tenant shall retain possession of the Premises or any
part thereof after the termination of this Lease, whether by lapse of time or otherwise, and also to pay all damages sustained by Landlord on account thereof (except that no damages, including consequential damages, shall be due from Tenant for any
holdover by Tenant lasting sixty (60) days or less); the provisions of this subsection shall not operate as a waiver by Landlord of any right of re-entry provided in this Lease; 

6.1.17 Hazardous Materials - Tenant shall not (either with or without negligence) cause or authorize the escape, disposal or release of
any Hazardous Materials onto, in or under the Premises, the Lot or Park, except in accordance with the requirements of applicable laws and regulations. Tenant shall not allow the storage or use of such substances or materials in any manner not
sanctioned by law or by the highest standards prevailing in the industry for the storage and use of such substances or materials, nor allow to be brought into the Premises any such materials or substances except to use in the ordinary course of
Tenant’s business, and then only after written notice is given to Landlord of the identity of such substances or materials. Landlord hereby consents to Tenant’s use of ordinary office and cleaning products in amounts reasonably necessary
for Tenant’s Permitted Use of the Premises. Without limitation, “Hazardous Materials” shall include those hazardous materials and substances described in the Comprehensive Environmental Response, Compensation and Liability Act of
1980, as amended, 42 U.S.C. Section 9601 et seq., the Resource Conservation and Recovery Act, as amended, 42 U.S.C. Section 6901 et seq., the Massachusetts Hazardous Waste Management Act, as amended, M.G.L. c.21C, the Massachusetts Oil and
Hazardous Material Release Prevention and Response Act, as amended, M.G.L. c.21E, any applicable local ordinance or bylaw, and the regulations adopted under these acts, (collectively, the “Hazardous Waste Laws”). If any lender or
governmental agency shall ever require testing to ascertain whether or not there has been any release of any Hazardous Materials, then the reasonable costs thereof shall be reimbursed by Tenant to Landlord within twenty (20) days after receipt
of demand as additional charges if and only if the following conditions are satisfied: (i) if such requirement applies to the Premises, and 

  
 - 29 - 








 
(ii) if an independent, reputable third party engineer employed by Landlord or persons acting under Landlord conclusively determines that such release has been or is likely to have been solely
and exclusively caused by Tenant or persons acting under Tenant’s control. If Tenant receives from any federal, state or local governmental agency any notice of violation or alleged violation of any Hazardous Waste Law by Tenant, or if Tenant
is obligated to give any notice under any Hazardous Waste Law, Tenant agrees to forward to Landlord a copy of any such notice within seven (7) business days of Tenant’s receipt or transmittal thereof (except if immediate response is
required of Landlord, in which event reasonable immediate notice to be given to Landlord). In addition, Tenant shall execute reasonable affidavits, representations and the like from time to time at Landlord’s reasonable request concerning
Tenant’s best actual knowledge or belief regarding the presence of Hazardous Materials on the Premises. In all events, Tenant shall indemnify Landlord in the manner elsewhere provided in this Lease from any release of Hazardous Materials on the
Premises or elsewhere in the Park occurring while Tenant is in possession if caused by Tenant or persons acting under Tenant’s control. Landlord shall indemnify Tenant from any release of Hazardous Materials on the Premises or elsewhere in the
Building, Lot or Park occurring while Tenant is in possession if caused by Landlord or persons acting under Landlord’s control. Landlord retains the right to inspect the Premises at all reasonable times, upon reasonable notice to Tenant and
compliance with Section 6.1,10, to ensure compliance with this paragraph. Tenant shall not be liable for any losses, costs, claims, liabilities or damages (including attorneys’ and consultants’ fees) of any type or nature, directly or
indirectly arising out of or in connection with any Hazardous Materials present at any time on or about the Premises, Building, Lot or Park, or the violation of any environmental Laws, except to the extent that any of the foregoing actually results
from the release or disposal of Hazardous Materials by Tenant or its agents, employees, contractors, sublessees or assignees. The within covenants shall survive the expiration or earlier termination of the Term; 

6.1.18 Tenant’s Authority - Tenant has the power and authority to enter into this Lease and perform the obligations of Tenant
hereunder. This Lease and all other documents executed and delivered by Tenant in connection herewith constitute legal, valid, binding and enforceable obligations of Tenant; 

6.1.19 Confidentiality - This Lease is a confidential document by and between Landlord and Tenant and Tenant agrees that this Lease
shall not be copied and distributed or circulated to any person(s) other than to such parties, and their respective mortgagees, successors or assigns, their legal counsel, accountants and brokers or to any prospective sublessees and assignees or
affiliates of Tenant, or to any prospective acquirers, investors, or lenders of Tenant, or to regulatory authorities, or to the directors, shareholders or officers of Tenant, unless required by law (including rules and regulations of the Securities
and Exchange Commission) or court order, without the prior written consent of Landlord. All public announcements regarding this Lease prior to Tenant’s occupancy hereunder must be approved by Landlord and Tenant in advance; and 

6.1.20 Signs and Advertising - Except as hereinafter expressly provided, Tenant will not place or suffer to be placed or maintained on
the exterior of the Premises, Building, or Lot, or elsewhere in the Park, or on the roof of the Building, any sign, decoration, lettering or advertising matter or any other thing of any kind. Tenant will, at its sole cost and expense, maintain such
sign, decoration, lettering, advertising matter, or other thing as may be permitted hereunder in good condition and repair at all times. 

  
 - 30 - 








 Tenant shall have the right, at its sole cost and expense, subject to applicable sign ordinances
and to Landlord’s prior approval (which shall not be unreasonably withheld, conditioned or delayed) and subject to receipt by Landlord of all required permits therefore, to have installed signage (which may be electrified) supplied by Tenant at
Tenant’s expense, customary or appropriate in the conduct of Tenant’s business and with other signage along Route 128/95 designating Tenant on the exterior of the Building at the location facing Route 128/95 to be agreed upon by both
Landlord and Tenant (“Tenant’s Signage”), provided that Tenant shall be leasing and occupying at all times at least one (1) full floor of the Building. Otherwise, Landlord shall have the right to remove Tenant’s Signage, at
Tenant’s expense. Tenant’s right to install signage on the Building is non-exclusive, Landlord hereby agreeing, however, not to offer exterior Building signage to other tenants of the Building unless such tenant leases at least one
(1) full floor in the Building. Landlord shall be responsible for installing Tenant’s Signage, at Tenant’s expense. Tenant’s name shall also be placed by Landlord on the Building directory, at no cost to Tenant. Notwithstanding
the foregoing, Landlord agrees to provide Tenant with a $25,000 allowance towards the cost of building signage as aforesaid in Section 3.1 of this Lease. Landlord acknowledges that the Tenant’s Signage will reflect the “One
Communications” name, In the event that Tenant changes its name during the Term, Tenant may change all then existing signage in the Building at its own expense, without prior approval of Landlord. 

Landlord and Tenant hereby further acknowledge and agree that Landlord, upon Tenant’s request, shall use reasonable efforts to obtain all
necessary permits and approvals in compliance with local codes and ordinances for Tenant’s Signage, at Tenant’s sole cost and expense. In no event shall Landlord be required to obtain such necessary permits and approvals therefor as a
condition of the Premises being deemed Ready for Occupancy as determined in accordance with said Section 3.2. Tenant shall reimburse Landlord for the actual third-party reasonable costs and expenses incurred by Landlord in connection with
obtaining said permits and approvals, including reasonable attorney’s fees and disbursements. Tenant agrees to cooperate with Landlord during the permitting process by (i) promptly executing the necessary documentation reasonably requested
by Landlord, and (ii) by furnishing the same to Landlord promptly upon Landlord’s request, but in no event later than five (5) business days following Landlord’s request.

CASUALTY AND TAKING 
  

	7.1	CASUALTY AND TAKING 

 In case during the Term any substantial part of the Premises, or

thereof or are taken by eminent domain or Landlord receives compensable damage by reason of anything lawfully done in pursuance of public or other authority, this Lease shall terminate at Landlord’s election, which may be made, notwithstanding

effective date of termination which shall be not less than thirty (30) nor more than sixty (60) days after the date of notice of such termination. If in any such case the Lease is not so terminated, Landlord shall use due diligence to put
the Premises, or in case of taking, what may remain thereof into substantially the condition immediately prior to the casualty, subject to applicable law and Landlord’s right to terminate this Lease (as above provided) if the net award of
insurance or damages are adequate, and a just proportion of the Fixed Rent and additional rent according to the nature and extent of the injury shall be abated until the Premises or such remainder shall have been put by Landlord in such condition;
and in case of a taking which permanently reduces the area of the Premises, a just proportion of the Fixed Rent and additional rent shall be abated for the remainder of the Term and an appropriate adjustment shall be made to the Annual Estimated
Operating Costs. 
  

	7.2	RESERVATION OF AWARD 

 Landlord reserves to itself any and all rights to receive awards
made for damages to the Premises, Building or Lot and the leasehold hereby created, or any one or more of them, accruing by reason of exercise of eminent domain or by reason of anything lawfully done in pursuance of public or other authority. Tenant
hereby releases and assigns to Landlord all Tenant’s rights to such awards, and covenants to deliver such further assignments and assurances thereof as Landlord may from time to time request, hereby irrevocably designating and appointing
Landlord as its attorney-in-fact to execute and deliver in Tenant’s name and behalf all such further assignments thereof. It is agreed and understood, however, that Landlord does not reserve to itself, and Tenant does not assign to Landlord,
any damages payable for (i) movable trade fixtures installed by Tenant or anybody claiming under Tenant, at its own expense, (ii) equipment, generators, furniture (including furniture purchased out of the Allowance (except in the event of
a continuing, uncured Event of Default as aforesaid)), personal property or other items of Tenant located in the Premises or on the Lot, or (iii) relocation and moving expenses recoverable by Tenant from such authority in a separate action.

  

	7.3	ADDITIONAL CASUALTY PROVISIONS

	 	(b)	In the event of any termination of this Lease pursuant to this Article 7, the Term of this Lease shall expire as of the effective termination date as fully and completely as if such date were the date herein originally
scheduled as the Term Expiration Date. Tenant shall have access to the Premises at Tenant’s sole risk for a period of sixty (60) days after the date of termination in order to remove Tenant’s personal property except as prohibited by
any applicable governmental agency or official. 

  

	 	(c)	 Notwithstanding any language to the contrary contained in this Article 7, if all or any substantial part of the Premises and/or the Building or Lot or
any part thereof 



  
 - 32 - 









	 	
(as hereinabove defined), shall be damaged by fire or other casualty or taken by eminent domain during the last twelve (12) months of the Term, as the Lease may have theretofore been
extended, then either Landlord or Tenant may terminate this Lease effective as of the date of such fire or other casualty or taking upon notice to the other as aforesaid. Also, notwithstanding anything to the contrary contained in this Article 7,
Tenant may render any notice of Landlord’s termination null and void by exercising early an option to extend the initial Term or then Extended Term of this Lease in accordance with Exhibit “F”. In the event of such early exercise,
Landlord and Tenant agree to determine the Fixed Rent for the applicable Extended Term at least twelve (12) months prior to the commencement date of the Extended Term in accordance with and in the manner set forth in said Exhibits “F”
and “H.” 

  

	 	(d)	Notwithstanding anything to the contrary contained in this Lease, if the Premises are damaged by any peril and Landlord does not elect to terminate this Lease or is not entitled to terminate this Lease pursuant to its
terms, then as soon as reasonably practicable, Landlord shall furnish Tenant with a written opinion of Landlord’s architect or construction consultant as to when the restoration work required of Landlord may be completed. Tenant shall have the
option to terminate this Lease in the event any of the following occurs, which option may be exercised by delivery to Landlord of a written notice of election to terminate within thirty (30) days after Tenant receives from Landlord the estimate
of the time needed to complete such restoration: (x) the Premises, with reasonable diligence, cannot be fully repaired by Landlord within nine (9) months after the damage or destruction; or (y) if the Premises are damaged by any peril
within ten (10) months of the last day of Term, and cannot be substantially restored within sixty (60) days after the date of such damage. During any period of construction hereunder, Landlord agrees to use reasonable efforts to relocate
Tenant to one of its other properties, if available and at no cost to Landlord. 

 ARTICLE 8 

RIGHTS OF MORTGAGEE 
  

	8.1	PRIORITY OF LEASE 

 Landlord shall have the option to subordinate this Lease to any
future mortgagee or deed of trust of the Lot or Building, or both (“the mortgaged premises”), provided that the holder thereof enters into an agreement with Tenant by the terms of which the holder will agree to recognize the rights of
Tenant under this Lease, assume the obligations of Landlord under this Lease and to accept Tenant as tenant of the Premises under the terms and conditions of this Lease in the event of acquisition of title by such holder through foreclosure
proceedings or otherwise and Tenant will agree to recognize the holder of such mortgage as Landlord in such event, which agreement shall be made to expressly bind and inure to the benefit of the successors and assigns of Tenant and of the holder and
upon anyone purchasing the mortgaged premises at any foreclosure sale. Any such mortgage to which this Lease shall be subordinated may contain such terms, provisions and conditions as the holder reasonably deems usual or customary. Further, Landlord
agrees to use diligent efforts to obtain and deliver to Tenant prior to the 

  
 - 33 - 








 
Commencement Date a Subordination, Non-Disturbance and Attornment Agreement (“SNDA”) from its current lender, Bank of America, N.A,, substantially in accordance with Exhibit
“J” attached hereto (or from any future lender in such form as may be reasonably requested by such future lender and reasonably agreed to by Tenant). 
  

	8.2	LIMITATION ON MORTGAGEE’S LIABILITY 

 Upon entry and taking possession of the
mortgaged premises for any purpose other than foreclosure, the holder of a mortgage shall have all rights of Landlord, and during the period of such possession, shall also have the duty to perform all Landlord’s obligations hereunder. Except
during such period of possession, no such holder shall be liable, either as mortgagee or as holder of a collateral assignment of this Lease, to perform, or be liable in damages for failure to perform any of the obligations of Landlord unless and
until such holder shall enter and take possession of the mortgaged premises for the purpose of foreclosing a mortgage. Upon entry for the purpose of foreclosing a mortgage, such holder shall be liable to perform all of the obligations of Landlord
accruing after said entry (including performance of obligations arising prior to said entry), provided that a discontinuance of any foreclosure proceeding shall terminate the liability of die holder as Landlord. 

 

	8.3	MORTGAGEE’S ELECTION 

 Notwithstanding any other provision to the contrary contained
in this Lease, if prior to the substantial completion of Landlord’s obligations under Article 3, any holder of a first mortgage on the mortgaged premises enters and takes possession thereof for the purpose of foreclosing the mortgage, such
holder may elect, by written notice given to Tenant and Landlord at any time within ninety (90) days after such entry and taking of possession, not to perform Landlord’s obligations under Article 3, and in such event such holder and all
persons claiming under it shall be relieved of all obligations to perform, and all liability for failure to perform, said Landlord’s obligations under Article 3, and Tenant may terminate this Lease and all its obligations hereunder by written
notice to Landlord and such holder given within thirty (30) days after the day on which such holder shall have given its notice as aforesaid. 
  

	8.4	NO PREPAYMENT OR MODIFICATION, ETC. 

 No Fixed Rent, additional rent, or any other charge
shall be paid more than ten (10) business days prior to the due dates thereof, and payments made in violation of this provision shall (except to the extent that such payments are actually received by a mortgagee in possession or in the process
of foreclosing its mortgage) be a nullity as against such mortgagee, and Tenant shall be liable for the amount of such payments to such mortgagee. No assignment of this Lease (except as set forth in Section 6.1.6 regarding Permitted
Transferees) and no agreement to make or accept any surrender, termination or cancellation of this Lease and no agreement to modify so as to reduce the Rent, change the Term, or otherwise materially change the rights and obligations of either party
under this Lease, shall be valid as against a mortgagee unless consented to in writing by such Landlord’s mortgagee and only as to mortgagees of record, if any, which consent shall not be unreasonably withheld, conditioned or delayed. 

  
 - 34 - 









	8.5	NO RELEASE OR TERMINATION 

 Except as provided in Section 8.7 below, no act or
failure to act on the part of Landlord which would entitle Tenant under the terms of this Lease, or by law, to be relieved of Tenant’s obligations hereunder or to terminate this Lease, shall result in a release or termination of such
obligations or a termination of this Lease unless (i) Tenant shall have first given written notice of Landlord’s act or failure to act to Landlord’s mortgagees of record, if any, the addresses for whom previously have been provided in
writing to Tenant, specifying the act or failure to act on the part of Landlord which could or would give basis to Tenant’s rights, and (ii) such mortgagees, after receipt of such notice, have failed or refused to correct or cure the
condition complained of within a reasonable time thereafter, but nothing contained in this Section 8.5 shall be deemed to impose any obligation on any such mortgagee to correct or cure any such condition. “Reasonable time” as used
above means and includes a reasonable time to obtain possession of the mortgaged premises, if the mortgagee elects to do so, and a reasonable time to correct or cure the condition if such condition is determined to exist. 

 

	8.6	CONTINUING OFFER 

 The covenants and agreements contained in this Lease with respect to
the rights, powers and benefits of a mortgagee (particularly, without limitation thereby, the covenants and agreements contained in tins Article 8) constitute a continuing offer to any person, corporation or other entity, which by accepting or
requiring an assignment of this Lease or by entry or foreclosure assumes the obligations herein set forth with respect to such mortgagee, and such mortgagee shall be entitled to enforce such provisions in its own name. Tenant agrees on request of
Landlord to execute and deliver from time to time any agreement which may reasonably be deemed necessary to implement the provisions of this Article 8, 
  

	8.7	MORTGAGEE’S APPROVAL 

 Landlord’s obligation to perform its covenants and
agreements hereunder is subject to the condition precedent that this Lease be approved by the holder of any senior mortgage of which the Premises are a part and by the issuer of any commitment to make a senior mortgage loan which is in effect on the
date hereof. Unless Landlord gives Tenant written notice within ten (10) business days after the date hereof that such holder or issuer, or both, disapprove this Lease, then this condition shall be deemed to have been satisfied or waived and
the provisions of this Section 8.7 shall be of no further force or effect. Should this Lease not be approved by such mortgagor, Tenant shall have the right to terminate this Lease without incurring any liability to Landlord. 

ARTICLE 9 

DEFAULT 
  

	9.1	EVENTS OF DEFAULT 

 It shall be an “Event of Default” under this Lease, if
(i) Tenant fails to pay Fixed Rent or additional rent for more than ten (10) days, after notice thereof specifying such failure and that 

  
 - 35 - 








 
such failure may be an Event of Default hereunder; (ii) Tenant fails to perform its other non-monetary obligations hereunder for more than thirty (30) days after notice thereof from
Landlord, together with such additional time, if any, as is reasonably required to cure the default if the default is of such a nature that it cannot reasonably be cured in thirty (30) days; or (iii) if Tenant makes any assignment for the
benefit of creditors, or files a petition under any bankruptcy or insolvency law; or (iv) if such a petition is filed against Tenant and is not dismissed within one hundred and twenty (120) days; or (v) if a receiver becomes entitled
to Tenant’s leasehold hereunder and it is not returned to Tenant within one hundred and twenty (120) days; or (vi) such leasehold is taken on execution or other process of law in any action against Tenant; Landlord and the agents and
servants of Landlord may, in addition to and not in derogation of any remedies for any preceding breach of covenant, immediately or at any tune thereafter while such default continues and without further notice except as required by applicable law
enter into and upon the Premises or any part thereof in the name of the whole and repossess the same as of Landlord’s former estate and expel Tenant and those claiming through or under Tenant and remove its and their effects without being
deemed guilty of any manner of trespass and without prejudice to any remedies which might otherwise be used for arrears of rent or prior breach of covenant, and upon such entry or mailing as aforesaid, this Lease shall terminate, but Tenant shall
remain liable as hereinafter provided. After the occurrence of an Event of Default as aforesaid, Tenant hereby waives all statutory rights of redemption, if any to the extent such rights may be lawfully waived, and Landlord, without notice to
Tenant, may store Tenant’s effects and those of any person claiming through or under Tenant at the expense and risk of Tenant and, if Landlord so elects, may sell such effects at public auction or private sale and apply the net proceeds to the
payment of all sums due to Landlord from Tenant, if any, and pay over the balance, if any, to Tenant. 
  

	9.2	TENANT’S OBLIGATIONS AFTER TERMINATION 

 In the event that this Lease is terminated
under any of the provisions contained in Section 9.1 or shall be otherwise terminated for breach of any obligation of Tenant, Tenant covenants as follows: 
  

	 	(a)	to pay forthwith to Landlord, as compensation, a lump sum equal to the total rent reserved for the residue of the Term. In calculating the rent reserved, there shall be included, in addition to the Fixed Rent and all
additional rent, the value of all other consideration agreed to be paid or performed by Tenant for said residue, less the net proceeds of any rents obtained by Landlord in reletting the Premises as provided in (b)(ii) below; and 


 

	 	(b)	 and, to the extent not received in (a) above or the extent Landlord elects, in its sole discretion, to proceed under this subparagraph
(b) rather than subparagraph (a), as an additional and cumulative obligation, to pay punctually to Landlord all of the sums and perform all of the obligations which Tenant covenants in this Lease to pay and to perform in the same manner and to
the same extent and at the same time as if this Lease had not been terminated. In calculating the amounts to be paid by Tenant under this subclause (b), Tenant shall be credited with: (i) any amount paid to Landlord as compensation as provided
in subclause (a) of this Section 9.2 (if Landlord elects to proceed pursuant to subclause (a)); and (ii) the 



  
 - 36 - 









	 	
net proceeds of any rents obtained by Landlord by reletting the Premises, after deducting all of Landlord’s expenses in connection with such reletting, including, without implied limitation,
all repossession costs, brokerage commissions, tenant improvements costs paid or tenant improvement allowances granted, fees for legal services, and any other expenses of reletting the Premises or preparing the Premises for the new tenant or
tenants. 

 Landlord agrees to use commercially reasonable efforts to relet the Premises following termination provided,
however, that Landlord: (x) may relet the Premises or any part or parts thereof for a term or terms which may, at Landlord’s option, be equal to or less than or exceed the period which would otherwise have constituted the balance of
the Term, and may grant such concessions and free rent as Landlord in its sole judgment considers advisable or necessary to relet same; (y) may make such alterations, repairs and decorations in the 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 sub clauses (x) and/or (y), or Landlord’s failure to relet or to collect the rent through reletting,
shall operate or be construed to release or reduce Tenant’s liability as aforesaid; and (z) shall have no duty to relet the Premises to a prospective tenant who is also interested in leasing other space that Landlord (or its
affiliate(s)) then has available. 
 So long as at least twelve (12) months of the Term remain unexpired at the time of such
termination, in lieu of any other damages of indemnity and in lieu of full recovery by Landlord of all sums payable under all the foregoing provisions of this Section 9.2, Landlord may, by written notice to Tenant, at any time after this Lease
is terminated under any of the provisions contained in Section 9.1, or is otherwise terminated for breach of any obligation of Tenant and before such full recovery, elect to recover, and Tenant shall thereupon pay, as liquidated damages, an
amount equal to the aggregate of the Fixed Rent and additional rent accrued under Article 4 in the twelve (12) months ended next prior to such termination (or if the Term has not yet commenced, the Fixed Rent and additional rent that would be
due for said time period) plus the amount of Fixed Rent and additional rent of any kind accrued and unpaid at the time of termination and less the amount of any recovery by Landlord under the foregoing provisions of this Section 9.2 up to the
tune of payment of such liquidated damages. 
 Nothing contained in this Lease shall, however, limit or prejudice the right of Landlord to
prove and obtain in proceedings for bankruptcy or insolvency by reason of the termination of this Lease, an amount equal to the maximum allowed by any statute or rule of law in effect at the time when, and governing the proceedings in which, the
damages are to be proved, whether or not the amount be greater, equal to, or less than the amount of the loss or damages referred to above.

 The failure of Landlord or of Tenant to seek redress for violation of,
or to insist upon the strict performance of any covenant or condition of this Lease or, with respect to such failure of Landlord, any of the Rules and Regulations referred to in Section 6.1.4, 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 an original violation. The receipt by Landlord of Fixed Rent or
additional rent with knowledge of the breach of any covenant of this Lease shall not be deemed a waiver of such breach by Landlord, unless such waiver be in writing signed by Landlord. No consent or waiver, express or implied, by Landlord or Tenant
to or of any breach of any agreement or duty shall be construed as a waiver or consent to or of any other breach of the same or any other agreement or duty. 
  

	10.8	NO ACCORD AND SATISFACTION 

 No acceptance by Landlord of a lesser sum than the Fixed
Rent and additional rent then due shall be deemed to be other than on account of the earliest installment of such rent due, nor shall any endorsement or statement on any check or any letter accompanying any check or payment as rent be deemed as
accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance of such installment or pursue any other remedy in this Lease provided. 

 

	10.9	CUMULATIVE REMEDIES 

 The specific remedies to which Landlord may resort under the terms
of this Lease are cumulative and are not intended to be exclusive of any other remedies or means of redress to which it may be lawfully entitled in case of any breach or threatened breach by Tenant of any provisions of this Lease. In addition to the
other remedies provided in this Lease, Landlord 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 or to a decree compelling specific
performance of any such covenants, conditions or provisions. 
  

	10.10	PARTIAL INVALIDITY 

 If any term, clause, provision, covenant or condition contained in
this Lease is adjudicated to be illegal or unenforceable, all other terms, clauses, provisions, covenants or conditions of this Lease shall remain in force and effect, and the term, clause, provision, covenant or condition held illegal or
unenforceable shall remain in effect as far as possible in accordance with the intention of the parties.

	10.11	LANDLORD’S RIGHT TO CURE 

 If Tenant shall at any time default, beyond applicable
notice and cure periods, in the performance of any material obligation under this Lease, Landlord shall have the right, but shall not be obligated, upon ten (10) business days’ prior written notice to Tenant and for non-material
obligations upon thirty (30) days’ notice to Tenant (except in the event of an emergency where at least verbal notice will be given as soon as reasonably possible), to enter upon the Premises and to perform such obligation, notwithstanding
the fact that no specific provision for such substituted performance by Landlord is made in this Lease with respect to such default. In performing such obligation, Landlord may make any payment of money or perform any other act. All sums so paid by
Landlord (together with interest at the rate set forth in Section 4.3 hereof), and all necessary incidental costs and expenses in connection with the performance of any such acts by Landlord, shall be deemed to be additional rent under this
Lease and shall be payable to Landlord immediately on demand. Landlord may exercise the foregoing rights without waiving any other of its rights or releasing Tenant from any of its obligations under this Lease. 

 

	10.12	ESTOPPEL CERTIFICATE 

 Tenant agrees on the Commencement Date, and from time to time
thereafter, upon not less than thirty (30) days’ prior written request by Landlord, to execute, acknowledge and deliver to Landlord a statement in writing in substantially the form attached hereto as Exhibit “K”. Landlord agrees
on the Commencement Date, and from time to tune thereafter, upon not less than thirty (30) days’ prior written request by Tenant, to execute, acknowledge and deliver to Tenant a statement in writing in substantially the form attached
hereto as Exhibit “K”. 
  

	10.13	WAIVER OF SUBROGATION 

 Any insurance carried by either party with respect to the
Premises and property therein or occurrences thereon shall, if the other party so requests and it can be so written without additional premium or with any additional premium which the other party agrees to pay, include a clause or endorsement
denying to the insurer rights of subrogation against the other party to the extent rights have been waived by the insured prior to the occurrence of injury or loss. Each party, notwithstanding any provisions of this Lease to the contrary, hereby
waives any rights of recovery against the other for injury or loss due to hazards covered by insurance containing such clause or endorsement to the extent of the indemnification received thereunder. 

 

	10.14	BROKERAGE 

 Landlord and Tenant each represent to the other that they have dealt with no
real estate brokers, finders, agents or salesmen in connection with this Lease, except Newmark, Knight & 

  
 - 40 - 








 
Frank and Grubb & Ellis Company (collectively, the “Broker”). Each party agrees to hold the other party harmless from and against all claims for brokerage commissions,
finder’s fees, or other compensation made by any other agent, broker, salesman or finder as a consequence of said party’s actions or dealings with any such agent, broker, salesman, or finder. Landlord agrees to pay a fee to the Broker
pursuant to a separate agreement. 
  

	10.15	COVENANTS INDEPENDENT 

 Each provision in this Lease constitutes an independent covenant,
enforceable separately from each other covenant set forth herein. To the extent any provision hereof or any application of any provision hereof may be declared unenforceable, such provision or application shall not affect any other provision hereof
or other application of such provision. Tenant acknowledges and agrees that Tenant’s obligation to pay Fixed Rent and additional rent is independent of any and all obligations of Landlord hereunder, with the result that Tenant’s sole
remedy for any alleged breach by Landlord of its obligation hereunder shall be to commence a judicial proceeding against Landlord seeking specific performance and/or damages. 
  


	10.16	ACCESS 

 Subject to the terms and provisions of this Lease and all laws applicable to the
Premises, Tenant shall have twenty-four (24) hours, seven (7) days per week, fifty-two (52) weeks per year, access to the Premises. 
  

	10.17	ENTIRE AGREEMENT 

 This Lease contains the entire and only agreement between the parties
as to the Premises, and no oral statements or representations or prior written matter not contained in this instrument shall have any force or effect. This Lease shall not be modified in any way except by a writing signed by both parties, 

 

	10.18	GOVERNING LAW 

 This Lease shall be governed by and construed and enforced in accordance
with the laws and the Courts of the Commonwealth of Massachusetts. 
  

	10.19	ADDITIONAL REPRESENTATIONS 

 Landlord represents and warrants to Tenant as follows: 

 

	 	(a)	that Landlord has the right, power and authority to enter into this Lease and grant Tenant quiet possession of the Premises and other rights set forth herein; and 


 

	 	(b)	that Landlord is the fee simple owner of the Lot and Building located thereon, and that Landlord (and/or its affiliate(s) or an affiliate(s) of The Gutierrez Company) are the fee simple owners of the Park;



  
 - 41 - 









	 	(c)	that the Building (including the Tenant’s Work) and the Lot (including all common areas) will, upon substantial completion of Tenant’s Work and issuance of all necessary permits and approvals required to be
obtained from any and all necessary governmental agencies prior to occupancy of the Premises by Tenant, if necessary, including without limitation, a certificate of occupancy from the Town of Burlington, which allows Tenant to use and occupy the
Premises as herein provided, comply with all dimensional, use, parking, loading and other zoning requirements of the Town of Burlington, and all applicable building codes and governmental requirements, including, without limitation, all ADA, local
and state requirements and regulations promulgated thereunder and other applicable laws and rules governing access to and use of facilities by people with disabilities, including the Massachusetts Architectural Access Board regulations;


  

	 	(d)	that the Premises and common areas and all equipment and systems servicing such areas, shall be in good working order and repair as of the Commencement Date; 


 

	 	(e)	that the health club facility and the cafe to be located in the Building shall be completed and open for use within sixty (60) days following the Commencement Date; and 


 

	 	(f)	that Landlord shall use good faith diligent efforts to obtain LEED certification for the base Building. 

  

	10.20	GENERATOR 

 Subject to the provisions hereinafter provided, Tenant shall have the right,
at no additional charge, to place a dedicated emergency generator and any other equipment, wiring, shaft space, etc. required in connection therewith on the roof of the Building or adjacent to the loading dock as agreed to by the parties, at
Tenant’s sole cost and expense. Subject to all applicable laws, Landlord shall install the same as part of Tenant’s Work. The cost of the concrete pad shall be borne by Landlord and the generator and associated equipment, and installation
thereof, shall be borne by Tenant and may be paid out of the Allowance described in Section 3.1 of this Lease. The size and the precise location of the installation shall not be unreasonably withheld, conditioned or delayed by Landlord. All
installations shall be in accordance with sound construction practices, and in accordance with applicable law, and in a good and workmanlike manner, and shall not materially interfere with other tenants of the Building or Park or decrease the number
of parking spaces on the Lot. The cost of any environmental review of the proposed equipment, if reasonably required, shall be at Tenant’s expense. Tenant shall be required to maintain the same at its sole cost in accordance with best industry
standards, and Landlord’s agent shall, if reasonably practicable, accompany Tenant and/or any agent of Tenant when making necessary repairs to such equipment. Tenant agrees to maintain insurance on such generator, and to name Landlord as an
additional insured thereon. Evidence of such insurance shall be provided to Landlord on or prior to the Commencement Date. 

  
 - 42 - 








 Tenant shall indemnify, defend and hold Landlord harmless from and against any and all liability
or loss arising (except as a result of the negligence or willful misconduct of Landlord, its agents, employees or contractors) from or out of the use or removal of such generator and related equipment. Upon expiration of the Term, Tenant shall be
responsible for the removal of the same and for repairing any damage caused therefrom. This Section shall survive the expiration or earlier termination of this Lease. 

ARTICLE 11 

SECURITY 
 Security
in the amount of Two Million Five Hundred Thousand Dollars ($2,500,000.00) shall be delivered by Tenant to Landlord on or prior to the Commencement Date (the “Security”). Such Security shall be, at Tenant’s option, in the form of
(i) cash, or (ii) a Letter of Credit in substantially the form attached hereto as Exhibit “M”, and in the case of such Letter of Credit shall (a) name the Landlord as its beneficiary, (b) expire not less than one
(1) year after the issuance thereof, and (c) be drawn on an FDIC-insured financial institution reasonably satisfactory to Landlord. Tenant shall, from time to time, as necessary, renew or replace or amend the Letter of Credit no fewer than
twenty-five (25) banking days prior to the expiration date of the Letter of Credit then held by Landlord, and if Tenant fails to renew or replace or amend said Letter of Credit or provide cash in the applicable amount by not later than
twenty-five (25) banking days prior to expiry date of the Letter of Credit, Landlord may draw upon such Letter of Credit and hold the proceeds thereof in an account as Security, without interest until Tenant provides to Landlord a replacement
letter of credit complying with the requirements for the original Letter of Credit as set forth above. So long as Tenant is not in material default of its obligations hereunder, the amount of the required Security shall be reduced in accordance with
the following schedule: $500,000 on the 1st day of month twenty five (25) of the Term; by an additional $500,000 on the 1st day of month
thirty seven (37) of the Term; by an additional $500,000 on the 1st day of month forty nine (49) of the Term; and by an additional $500,000 on the 1st day of month sixty-one (61) of the Term. Thereafter, the Security shall be Five Hundred Thousand Dollars and 00/100 ($500,000.00). Failure of the Landlord to release any cash Security in
accordance with the foregoing scheduled shall constitute a default by Landlord. In the event that Landlord fails to release the required funds within five (5) business days following the required date (assuming a cash deposit), Landlord shall
be obligated to pay Tenant interest on any such amount at the Agreed Interest Rate, calculated on a daily basis. 
 Landlord may, from time
to time, without prejudice to any other remedy, use all or a portion of the Security to cure any continuing Event of Default, including any uncured default in connection with any arrearages of Rent, costs incurred by Landlord to repair damage to the
Premises caused by Tenant, and any costs incurred by Landlord to repair (other than normal wear and tear or damage caused by Landlord, its agents or employees) the Premises upon termination of this Lease. Following any such application of the
Security, Tenant shall, within ten (10) business days after receipt of written demand, restore the cash security or Letter of Credit to the then applicable full amount. Tenant shall not have the right to call upon Landlord to apply all or any
part of the Security to cure any continuing Event of Default, but such use shall be solely in the discretion of Landlord. If there is no continuing Event of Default, at the termination of this Lease, after Tenant surrenders the Premises to Landlord
in accordance with this Lease and all 

  
 - 43 - 








 
amounts then due Landlord from Tenant are finally determined and paid by Tenant or through application of the Security, the balance of the Security, either cash or the Letter of Credit, as
applicable, shall be returned to Tenant within ten (10) business days of expiration of the Term and surrender of the Premises, whichever may be later. If Landlord transfers its interest in the Premises during the Term, Landlord shall assign the
Security to the transferee, Landlord shall promptly notify Tenant of the assignment in advance and thereafter have no further liability for the return of the Security. If the Security is in the form of a Letter of Credit, Landlord shall have no
further liability for the return of such Letter of Credit once the Letter of Credit has been appropriately assigned to the assignee, the assignee has assumed all of Landlord’s obligations under this Lease, it and Landlord has notified Tenant,
in writing, of both. Upon any such delivery and assignment, Tenant hereby releases the then existing Landlord of any and all liability with respect to the Letter of Credit, its application and return, and Tenant agrees to look solely to such
assignee or transferee. It is further understood that this provision shall also apply to subsequent assignees or transferees. Upon request by Tenant, Landlord shall provide Tenant with a copy of the assignment and assumption or other written
documentation that was entered into to effectuate the transfer of the Letter of Credit and this Lease. Landlord shall not be required to segregate the Security from its other accounts or, except as otherwise specified herein, to pay interest
thereon, as aforesaid. 
 In the event the Lease is assigned by Tenant, Tenant’s assignee may provide a replacement Letter of Credit
and the original Letter of Credit held by Landlord shall be promptly returned to Tenant, provided that such Letter of Credit shall remain subject to all of the terms and conditions of this Article 11. Landlord shall deliver the original prior Letter
of Credit to the prior tenant simultaneously upon the delivery of the replacement Letter of Credit by Tenant’s assignee or as soon as possible thereafter.

thereof shall be paid for by Tenant, as additional rent, upon Landlord’s demand, so long as no other tenants are receiving excess usage. 

It is understood that the electrical generated service to the Premises may be furnished by one or more generators of electrical power and that
the cost of electricity may be billed as a single charge or divided into and billed in a variety of categories, such as distribution charges, transmission charges, generation charges, congestion charges, capacity charges, public good charges, and
other similar categories, and may also include a fee, commission or other charge by an unaffiliated broker, aggregator or other intermediary for obtaining or arranging the supply of generated electricity. Landlord shall have the right to select the
generator of electricity to the Premises and to purchase generated electricity for the Premises through a broker, aggregator or other intermediary and/or buyers group or other group and to change the generator of electricity and/or manner of
purchasing electricity from time to time. 
 If Landlord successfully undertakes activities for the purpose of reducing Tenant’s
operating costs (such as negotiating an agreement with a utility or another energy generator or engaging an energy consultant or undertaking conservation or other energy efficient measures that may require capital expenditures), Tenant shall pay its
proportionate share of all out of pocket costs and expenses associated with such actions (including, but not limited to, brokers’ commissions and legal fees, but excluding capital expenditures, which shall be amortized and paid by Tenant as set
forth in Section 4.2 of the Lease), as additional rent, if, as and when payment is made by Landlord with no profit to Landlord.

MARKET RENT 
 The market rent for
the Premises shall be the then fair market rent for similar space in similar buildings (size, length of term, age and location) in the Town of Burlington, which such rent (the “Market Rent”) shall be determined as follows: 

 

	(a)	The Market Rent shall be proposed by Landlord within fifteen (15) business days of receipt of Tenant’s notice that it intends to exercise its option to extend the Term as specified in Exhibit “F”
(the “Landlord’s Proposed Market Rent”), The Landlord’s Proposed Market Rent shall be the Market Rent unless Tenant notifies Landlord, within fifteen (15) business days of Tenant’s receipt of Landlord’s Proposed
Market Rent that Landlord’s Proposed Market Rent is not satisfactory to Tenant (“Tenant’s Rejection Notice”). 

  

	(b)	If Tenant delivers Tenant’s Rejection Notice and the Market Rent is not otherwise agreed upon by Landlord and Tenant within forty-five (45) days after Landlord’s receipt of Tenant’s notice that it
intends to exercise its option to extend the Term, then the Market Rent shall be determined by the following appraisal procedure: 

  

	 	1.	Within five (5) business days of the expiration of said forty-five (45) day period, Tenant shall give notice to Landlord, which notice shall specify the name and address of the appraiser designated by Tenant
(the “Tenant’s Appraisal Notice”). Landlord shall within five (5) business days after receipt of Tenant’s Appraisal Notice, notify Tenant of the name and address of the appraiser designated by Landlord. Such two appraisers
shall, within twenty (20) business days after the designation of the second appraiser, make their determinations of the Market Rent in writing and give notice thereof to each other and to Landlord and Tenant. Such two (2) appraisers shall
have twenty (20) business days after the receipt of notice of each other’s determination to confer with each other and to attempt to reach agreement as to the determination of the Market Rent. If such appraisers shall concur in such
determination, they shall give notice thereof to Landlord and Tenant and such concurrence shall be final and binding upon Landlord and Tenant. If such appraisers shall fail to concur as to such determination within said twenty (20) business day
period, they shall give notice thereof to Landlord and Tenant and shall immediately designate a third appraiser. If the two appraisers shall fail to agree upon the designation of such thud appraiser within five (5) business days after said
twenty (20) business day period, then they or either of them shall give notice of such failure to agree to Landlord and Tenant and if Landlord and Tenant fail to agree upon the selection of such third appraiser within five (5) business
days after the appraisers) appointed by the parties give notice as aforesaid, then either party on behalf of both may apply to the American Arbitration Association or any successor thereto, or on his or her failure, refusal or inability to act, to a
court of competent jurisdiction, for the designation of such third appraiser.

	 	3.	The third appraiser shall conduct such hearings and investigations as he or she may deem appropriate and shall) within ten (10) business days after the date of his or her designation, make an independent
determination of the Market Rent. 

  

	 	4.	If none of the determinations of the appraisers varies from the mean of the determinations of the other appraisers by more than ten (10%) percent, the average of the determinations of the three (3) appraisers
shall be the Market Rent for the Premises. If, on the other hand, the determination of any single appraiser varies from the average of the determinations of the other two (2) appraisers by more than ten (10%) percent, the average of the
determination of the two (2) appraisers whose determinations are closest shall be the Market Rent. 

  

	 	5.	The determination of the appraisers, as provided above, shall be conclusive upon file parties and shall have the same force and effect as a judgment made in a court of competent jurisdiction. 


 

	 	6.	Each party shall pay fees, costs and expenses of the appraiser selected by it, its own counsel fees, and one-half (1/2) of all other expenses and fees of any such third appraisal. 








 EXHIBIT “I” 

RIGHT OF FIRST REFUSAL 

In no event shall Landlord, during the Term hereunder, lease or decide to lease, agree to lease, or accept any offer to lease space that from
time to time becomes available during the Term on any portion of the fourth (4th) floor within the Building (each and collectively, the “ROFR Space”), unless Landlord first affords
Tenant an opportunity to lease such area in accordance with the provisions of this Exhibit “I” and only after written notice to Tenant, provided that there does not then exist an uncured, continuing material default under this
Lease. Such notice shall contain Landlord’s summary of the essential terms and conditions of any bonafide, third party written offer received by Landlord (i.e., description of such rentable area, the term and any options to extend or cancel the
term, the annual fixed rent amounts, the basic operating cost provisions, and the allowances and other monetary concessions, if any) with respect to such rentable area (such summary shall herein in this Exhibit “I” be referred to as the
“Offer”). Upon receipt of such notice and the Offer from Landlord, and as aforesaid, provided further that there does not then exist an uncured, continuing material default under this Lease, then Tenant shall have a right to lease any such
space on the terms set forth in the Offer (except as hereinafter provided) by giving notice to Landlord to such effect within seven (7) business days after Tenant’s receipt of Landlord’s notice of such Offer, If such notice is not so
timely given by Tenant, then Landlord shall be free to lease the subject space, or portion thereof, to such third party on the terms and conditions contained in the Offer. If Tenant declines to lease the space covered by the Offer and Landlord fails
to close the leasing transaction contemplated within the Offer within three (3) months after Tenant’s receipt of the Offer, Landlord shall repeat the process set forth above prior to leasing the space covered by the Offer. The non-exercise
by Tenant of its rights under this Exhibit “I” as to any one Offer by Landlord shall not be deemed to waive any of Tenant’s rights of first refusal as to the remainder of space that becomes available within the ROFR Space, or as to
the rentable area described in the Offer if Landlord determines to modify or amend the terms by more than five percent (5%) of the aforesaid net effective rent offered in such notice and Offer given by Landlord to Tenant hereunder (in which
event Tenant’s rights hereunder shall revive and continue with respect to such modified or amended terms) or the space covered by the Offer following expiration of any lease executed with respect to such space. 

In the event that Tenant accepts Landlord’s offer to lease such rentable space within the ROFR Space, then Landlord and Tenant hereby
agree that they shall enter into a mutually acceptable amendment to this Lease, specifying that such rentable area is a part of the Premises under this Lease and demising said premises to Tenant on the terms of the Offer with respect to such
rentable space. Such amendment shall also contain other appropriate terms and provisions relating to the addition of such rentable space to this Lease or the leasing of such rentable space, as applicable, and as mutually agreed upon by the parties.
The amendment shall be signed by Tenant within twenty (20) business days of receipt of the proposed agreement from the Landlord in the form as hereinabove required, Landlord and Tenant hereby agreeing to use good faith








 
efforts to finalize the form of amendment as quickly as possible and within said twenty (20) business day period. In no event shall the foregoing affect the Tenant’s obligation to lease
such space once Tenant provides Landlord with its notice exercising its option hereunder as aforesaid, as the parties hereby agree that Tenant’s notice shall serve as Tenant’s acceptance of Landlord’s offer to lease such space and
that the amendment merely serves as confirmation that the parties shall enter into a written amendment to memorialize the previously accepted terms. 

Notwithstanding anything to the contrary in this Exhibit “I”, if Tenant notifies Landlord of its election to lease such rentable
space within the ROFR Space and then fails to execute and deliver the required amendment to this Lease once the terms of the amendment have been mutually agreed upon by Landlord and Tenant in accordance with this Exhibit “I”, than
Tenant’s right of first refusal as to any other rentable space within the ROFR Space, as applicable, shall terminate and be of no further force and effect. The recording by the Landlord of an affidavit to such effect shall be conclusive
evidence of the termination of Tenant’s first refusal hereunder.

SUBORDINATION, NON-DISTURBANCE 

AND ATTORNMENT AGREEMENT 

[SUBJECT TO FINAL LENDER APPROVAL 

SUBORDINATION, NON-DISTURBANCE AND ATTORNMENT AGREEMENT

Owner”), Tenant shall attorn to the New Owner as Tenant’s new landlord, and agrees that the Lease shall continue in full force and effect as a direct lease between Tenant and New Owner upon all of the terms, covenants, conditions and
agreements set forth in the Lease and this Agreement, except for provisions which are impossible for New Owner to perform; provided, however, that in no event shall the New Owner be; 

(i) liable for any act, omission, default, misrepresentation, or breach of warranty, of any previous landlord (including
Landlord) or obligations accruing prior to New Owner’s actual ownership of the Property; 
 (ii) subject to any offset,
defense, claim or counterclaim which Tenant might be entitled to assert against any previous landlord (including Landlord); 

(iii) bound by any payment of rent, additional rent or other payments, made by Tenant to any previous landlord (including

(including Landlord) which has not, as such, been transferred to New Owner. 
 (b) The provisions of this Agreement regarding
attornment by Tenant shall be self-operative and effective without the necessity of execution of any new lease or other document on the part of any party hereto or the respective heirs, legal representatives, successors or assigns of any such party.

Premises on the same terms and conditions as the Lease for the unexpired term of the Lease. 
 4. Estoppel Certificate. Tenant agrees
to execute and deliver from time to time, upon the request of Landlord or of any holder(s) of any of the indebtedness or obligations secured by the Mortgage, a certificate regarding the status of the Lease, consisting of statements, if true (or if

modifications of the Lease, (e) to the best of Tenant’s knowledge no default, or state of facts which with the passage of time or notice (or both) would constitute a default, exists under the Lease, (f) to the best of Tenant’s
knowledge, no setoffs, recoupments, estoppels, claims or counterclaims exist against Landlord, and (g) such other matters as may be reasonably requested. 

5. Acknowledgment and Agreement by Tenant. Tenant acknowledges and agrees as follows:

consents to such assignment and agrees that such assignment shall, in all respects, be superior to any interest Tenant has in the Lease of the Property, subject to the provisions of this Agreement. Tenant will not amend, alter or waive any provision
of, or consent to the amendment, alteration or waiver of any provision of the Lease without the prior written consent of Mortgagee. Tenant shall not prepay any rents or other sums due under the lease for more than one (1) month in advance of
the due date therefor. Tenant acknowledges that Mortgagee will rely upon this instrument in connection with such financing. 

(b) Mortgagee, in making any disbursements to Landlord, is under no obligation or duty to oversee or direct the application of
the proceeds of such disbursements, and such proceeds may be used by Landlord for purposes other than improvement of the Property. 

(c) From and after the date hereof, in the event of any act or omission by Landlord which would give Tenant the right, either
immediately or after the lapse of time, 







 
to terminate the Lease or to claim a partial or total eviction, Tenant will not exercise any such right (i) until it has given written notice of such act or omission to the Mortgagee; and
(ii) until the same period of time as is given to Landlord under the Lease to cure such act or omission shall have elapsed following such giving of notice to Mortgagee and following the time when Mortgagee shall have become entitled under the
Mortgage to remedy the same, but in any event thirty (30) days after receipt of such notice or such longer period of time as may be necessary to cure or remedy such default, act, or omission including such period of time necessary to obtain
possession of the Property and thereafter cure such default, act, or omission, during which period of time Mortgagee shall be required to cure or remedy such default, act or omission. It is specifically agreed that Tenant shall not, as to Mortgagee,
require cure of any such default which is personal to Landlord, and therefore not susceptible to cure by Mortgagee, 
 (d) In
the event that Mortgagee notifies Tenant of a default under the Mortgage, Note, or Security Documents and demands that Tenant pay its rent and all other sums due under the Lease directly to Mortgagee, Tenant shall honor such demand and pay the full
amount of its rent and all other sums due under the Lease directly to Mortgagee, without offset, or as otherwise required pursuant to such notice beginning with the payment next due after such notice of default, without inquiry as to whether a
default actually exists under the Mortgage, Security Documents or otherwise in connection with the Note, and notwithstanding any contrary instructions of or demands from Landlord. 

(e) Tenant shall send a copy of any notice or statement under the Lease to Mortgagee at the same time such notice or statement
is sent to Landlord if such notice or statement has a material impact on the economic terms, operating covenants or duration of the Lease. 

(f) Tenant has no right or option of any nature whatsoever, whether pursuant to the Lease or otherwise, to purchase the
Premises or the Property, or any portion thereof or any interest therein, and to the extent that Tenant has had, or hereafter acquires, any such right or option, same is hereby acknowledged to be subject and subordinate to the Mortgage and is hereby
waived and released as against Mortgagee and New Owner. 
 (g) This Agreement satisfies any condition or requirement in the
Lease relating to the granting of a non-disturbance agreement and Tenant waives any requirement to the contrary in the Lease. 

(h) Mortgagee and any New Owner shall have no liability to Tenant or any other party for any conflict between the provisions of
the Lease and the provisions of any other lease affecting the Property, including, but not limited to, any provisions relating to exclusive or non-conforming uses or rights, renewal options and options to expand, and in the event of such a conflict,
Tenant shall have no right to cancel the Lease or take any other remedial action against Mortgagee or New Owner, or against any other party for which Mortgagee or any New Owner would be liable. 







 (i) Notwithstanding anything to the contrary in the Lease or the Security
Documents, neither Mortgagee nor any New Owner shall be liable for or bound by any Construction-Related Obligation under the Lease. As used herein, a “Construction-Related Obligation” means any obligation of Landlord under the Lease to
make, pay for, or reimburse Tenant for any alterations, demolition, or other improvements or work at the Property, including the Premises. 

(j) Mortgagee and any New Owner shall have no obligation nor incur any liability with respect to any warranties of any nature
whatsoever, whether pursuant to the Lease or otherwise, including, without limitation, any warranties respecting use, compliance with zoning, Landlord’s title, Landlord’s authority, habitability, fitness for purpose or possession, 

(k) In the event that Mortgagee or any New Owner shall acquire title to the Premises or the Property, Mortgagee or such New
Owner shall have no obligation, nor incur any liability, beyond Mortgagee’s or New Owner’s then equity interest, if any, in the Property or the Premises, and Tenant shall look exclusively to such equity interest of Mortgagee or New Owner,
if any, for the payment and discharge of any obligations imposed upon Mortgagee or New Owner hereunder or under the Lease or for recovery of any judgment from Mortgagee, or New Owner, and in no event shall Mortgagee, New Owner, nor any of their
respective officers, directors, shareholders, agents, representatives, servants, employees or partners ever be personally liable for such judgment. 

(l) Tenant has never permitted, and will not permit, the generation, treatment, storage or disposal of any hazardous substance
as denned in the Lease on the Premises or Property except for such substances of a type and only in a quantity normally used in connection with the occupancy or operation of buildings (such as non-flammable cleaning fluids and supplies normally used
in the day to day operation of first class establishments similar to the Improvements), which substances are being held, stored, and used in strict compliance with federal, state, and local laws. Tenant shall be solely responsible for and shall
reimburse and indemnify Landlord, New Owner or Mortgagee, as applicable, for any loss, liability, claim or expense, including without limitation, cleanup and all other expenses, including, without limitation, legal fees that Landlord, New Owner or
Mortgagee, as applicable, may incur by reason of Tenant’s violation of the requirements of this Paragraph 5(1). 
 6. Acknowledgment
and Agreement by Landlord. Landlord, as landlord under the Lease and grantor under the Mortgage, acknowledges and agrees for itself and its heirs, representatives, successors and assigns, that: (a) this Agreement does not constitute a
waiver by Mortgagee of any of its rights under the Mortgage, Note, or Security Documents, or in any way release Landlord from its obligations to comply with the terms, provisions, conditions, covenants, agreements and clauses of the Mortgage, Note,
or Security Documents; (b) the provisions of the Mortgage, Note, or Security Documents remain in full force and effect and must be complied with by Landlord; and (c) Tenant is hereby authorized to pay its rent and all








 
other sums due under the Lease directly to Mortgagee upon receipt of a notice as set forth in paragraph 5(d) above from Mortgagee and that Tenant is not obligated to inquire as to whether a
default actually exists under the Mortgage, Security Documents or otherwise in connection with the Note. Landlord hereby releases and discharges Tenant of and from any liability to Landlord resulting from Tenant’s payment to Mortgagee in
accordance with this Agreement. Landlord represents and warrants to Mortgagee that a true and complete copy of the Lease has been delivered by Landlord to Mortgagee. 

7. Lease Status. Landlord and Tenant certify to Mortgagee that neither Landlord nor Tenant has knowledge of any default on the
part of the other under the Lease, that the Lease is bona fide and contains all of the agreements of the parties thereto with respect to the letting of the Premises and that all of the agreements and provisions therein contained are in full force
and effect. 
 8. Notices. All notices, requests, consents, demands and other communications required or which any party
desires to give hereunder shall be in writing and shall be deemed sufficiently given or furnished if delivered by personal delivery, by facsimile, by overnight courier with proof of delivery, or by registered or certified United States mail, postage
prepaid, at the addresses specified at the end of this Agreement (unless changed by similar notice in writing given by the particular party whose address is to be changed). Any such notice or communication shall be deemed to have been given either
at the time of personal delivery or, in the case of delivery service or mail, as of the date of first attempted delivery at the address and in the manner provided herein, or, in the case of facsimile, upon receipt of a machine confirmation that the
facsimile has been sent. Notwithstanding the foregoing, no notice of change of address shall be effective except upon receipt. This Paragraph 8 shall not be construed in any way to affect or impair any waiver of notice or demand provided in this
Agreement or in the Lease or in any document evidencing, securing or pertaining to the loan evidenced by the Note or to require giving of notice or demand to or upon any person in any situation or for any reason. 

9. Miscellaneous, 

(a) This Agreement supersedes any inconsistent provision of the Lease. 

(b) Nothing contained in this Agreement shall be construed to derogate from or in any way impair, or affect the lien, security
interest or provisions of the Mortgage, Note, or Security Documents. 
 (c) This Agreement shall inure to the benefit of the
parties hereto, their respective successors and permitted assigns, and any New Owner, and its heirs, personal representatives, successors and assigns; provided, however, that in the event of the assignment or transfer of the interest of Mortgagee,
all obligations and liabilities of the assigning Mortgagee under this Agreement shall terminate, and thereupon all such obligations and liabilities shall be the responsibility of the party to whom Mortgagee’s interest is assigned or
transferred; and provided further that the interest of Tenant under this Agreement may not be assigned or transferred without the prior written consent of Mortgagee. 







 (d) THIS AGREEMENT AND ITS VALIDITY, ENFORCEMENT AND INTERPRETATION SHALL BE
GOVERNED BY THE LAWS OF THE COMMONWEALTH OF MASSACHUSETTS AND APPLICABLE UNITED STATES FEDERAL LAW EXCEPT ONLY TO THE EXTENT, IF ANY, THAT THE LAWS OF THE STATE IN WHICH THE PROPERTY IS LOCATED NECESSARILY CONTROL. 

(e) The words “herein”, “hereof, “hereunder” and other similar compounds of the word “here”
as used in this Agreement refer to this entire Agreement and not to any particular section or provision. 
 (f) This
Agreement may not be modified orally or in any manner other than by an agreement in writing signed by the parties hereto or their respective successors in interest. 

(g) If any provision of the Agreement shall be held to be invalid, illegal, or unenforceable in any respect, such invalidity,
illegality or unenforceability shall not apply to or affect any other provision hereof, but this Agreement shall be construed as if such invalidity, illegality, or unenforceability did not exist.

 EXHIBIT “N” 

EARLY TERMINATION OPTION 
 So long as there
does not then exist an uncured, continuing, material, Event of Default as defined in Section 9.1 of this Lease, Tenant may, at its sole option, terminate this Lease (the “Termination Option”) effective on the first (1st) day of month eighty four (84) of the Term (the “Early Termination Date”), by delivering notice of Tenant’s election to terminate (the “Termination Notice”) to
Landlord during month seventy-two (72) of the Term, provided that Tenant pays to Landlord on or before the Early Termination Date a payment equal to the “Termination Fee” as set forth below. 

If Tenant fails to timely deliver its Termination Notice or pay the Termination Fee as provided above, then Tenant will be deemed to have waived such
Termination Option. The Termination Fee shall be equal to the unamortized balance of all Landlord’s Transaction Costs as of the Early Termination Date. If Tenant properly exercises its Termination Option in accordance with the foregoing, then
the Lease shall automatically terminate as of the Early Termination Date without the necessity of any additional documentation. The term “Landlord’s Transaction Costs” as used above shall include, for example, the brokerage
commissions paid to the broker(s) and the tenant improvement work completed in the Premises, architectural and engineering fees, legal fees and costs and any other cost or rental abatements or concessions that were provided to Tenant under the Lease
(together with an interest rate equal to eight percent (8%) per annum), plus one year’s rent at such time, for an aggregate Termination Fee equal to $76.16/RSF, pursuant to the Schedule attached hereto as Exhibit “N-1”.

GUARANTY 
 In
consideration of the execution and delivery by Burlington Office Park V Limited Partnership, a Massachusetts limited partnership (together with its successors and assigns, “Landlord”), of the Lease dated as of July 2, 2008 as amended,
supplemented, or otherwise modified from time to time (the “Lease”) between Landlord and Conversent Communications of Massachusetts, Inc. d/b/a One Communications, a Massachusetts corporation (together with its successors and assigns
“Tenant”), and as an inducement to Landlord to execute the Lease with Tenant, the undersigned “Guarantor” hereby guarantees to Landlord the payment by Tenant when due of the Fixed Rent and the additional rent (including any
Operating Cost Escalation due under Section 4.2 of the Lease) and all other Rent or other payment obligations payable under the Lease (collectively, the “Guaranteed Obligations”). It is specifically understood and agreed that this
Guaranty is not a guaranty of performance of any of Tenant’s obligations under the Lease other than the Guaranteed Obligations. The Guarantor hereby consents to and waives notice of any extensions of time for performance which Landlord may
grant to Tenant and to any modifications or amendments to the Lease to which Landlord and Tenant may agree. All capitalized terms used but not defined herein shall have the meanings assigned to such terms in the Lease. 

This Guaranty is an absolute, unconditional and continuing guaranty of the full and punctual payment of the Guaranteed Obligations and is in
no way conditioned upon any requirement that the Landlord first attempt to collect any of the Guaranteed Obligations from the Tenant or resort to any security or other means of obtaining their payment. Should the Tenant default in the payment of any
of the Guaranteed Obligations, the obligations of the Guarantor hereunder shall become immediately due and payable to the Landlord upon demand. Payments by the Guarantor hereunder may be required by the Landlord on any number of occasions. 

The Guarantor further agrees that the Guarantor’s liability under this Guaranty shall be primary, and that in any right of action which
may accrue to Landlord, under the Lease or this Guaranty. 
 The Guarantor agrees that the Guaranteed Obligations will be paid and performed
strictly in accordance with their respective terms regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of the Landlord with respect thereto. The Guarantor waives
presentment, demand, protest, notice of acceptance, notice of Guaranteed Obligations incurred and all other notices of any kind, all defenses which may be available by virtue of any valuation, stay, moratorium law or other similar law now or
hereafter in effect, any right to require the marshaling of assets of the Tenant, and all suretyship defenses generally. Without limiting the generality of the foregoing, the Guarantor agrees that the obligations of the Guarantor hereunder shall not
be released or discharged, in whole or in part, or otherwise affected by (i) the failure of the Landlord to assert any claim or demand or to enforce any right or remedy against the Tenant; (ii) any extensions or renewals of the Lease;
(iii)







 
any rescissions, waivers, amendments or modifications of any of the terms or provisions of the Lease; (iv) the substitution or release of any entity primarily liable for any Guaranteed
Obligations; (v) the adequacy of any rights the Landlord may have against any collateral or other means of obtaining repayment of the Guaranteed Obligations; (vi) if applicable, the impairment of any collateral securing the Guaranteed
Obligations, including without limitation the failure to perfect or preserve any rights the Landlord might have in such collateral or the substitution, exchange, surrender, release, loss or destruction of any such collateral; or (vii) any other
act or omission which might in any manner or to any extent vary the risk of the Guarantor or otherwise operate as a release or discharge of the Guarantor, ah of which may be done without notice to the Guarantor. 

If for any reason the Tenant has no legal existence or is under no legal obligation to discharge any of the Guaranteed Obligations, or if any
of the Guaranteed Obligations have become irrecoverable from the Tenant by operation of law or for any other reason, this Guaranty shall nevertheless be binding on the Guarantor to the same extent as if the Guarantor at all times had been the
principal obligor on all such Guaranteed Obligations. In the event that acceleration of the time for payment of the Guaranteed Obligations is stayed upon the insolvency, bankruptcy or reorganization of the Tenant, or for any other reason, all such
amounts otherwise subject to acceleration under the terms of any agreement evidencing or securing or otherwise executed in connection with any Guaranteed Obligation shall be immediately payable by the Guarantor. 

Guarantor hereby agrees that this Guaranty is made and executed under and shall be construed in accordance with the laws of the Commonwealth
of Massachusetts without regard to conflicts of law principles, that the Courts of the Commonwealth of Massachusetts shall have jurisdiction of any action brought upon this Guaranty, and that venue may be placed in the Superior Court of Middlesex
County with service of process in accordance with the Massachusetts Code of Civil Procedure as then in effect. Guarantor further agrees that General Counsel, with the notice address set forth below, may serve as agent for service of process for any
action instituted by Landlord under this Guaranty. Any such service of process by mail may be made by certified mail, return receipt requested, addressed to the undersigned at the following address (or at such other address as the Guarantor may so
notify the Landlord in accordance with Section 10.3 of the Lease): 
 Five Wall Street 

Burlington, MA 01803 

Attention: General Counsel 

Landlord may, without notice, assign this Guaranty in whole or in part, and no assignment or transfer of the Lease shall operate to extinguish
or diminish the liability of Guarantor hereunder. 
 In the event an action is commenced by Landlord against the Guarantor under this
Guaranty and the Landlord prevails in such suit, the Guarantor agrees to pay all costs and expenses, including reasonable attorney’s fees, incurred by Landlord therein, which obligation on the part of the undersigned shall he deemed to have
accrued on the date of the commencement 







 
of the action. In addition, in the event that Landlord commences an action against the Guarantor and does not prevail, Landlord agrees to pay all costs and expenses, including reasonable
attorneys’ fees, incurred by Tenant in the defense of such claims.

 AMENDMENT TO SUBLEASE 

THIS FIRST AMENDMENT TO SUBLEASE (this “Amendment”), effective as of April 14, 2014 (the “Effective
Date”), is entered into by and between EARTHLINK, LLC, a Delaware limited liability company (“Sublandlord”), and DEMANDWARE, INC., a Delaware corporation (“Subtenant”). 

RECITALS 
 WHEREAS, by Lease
Agreement dated July 2, 2008 (the “Master Lease”), Sublandlord (as successor in interest to Conversant Communications of Massachusetts, Inc., d/b/a EarthLink Business, a Delaware corporation) leases approximately 75,495
rentable square feet of space located on the Fifth and Sixth Floors at Five Wall Street, Burlington, Massachusetts 01803 (the “Leased Premises”) from Burlington Office Park V Limited Partnership
(“Landlord”). A copy of the Master Lease is attached as Exhibit A to the Sublease (as defined below). 

WHEREAS, Sublandlord and Subtenant entered into that certain Sublease dated January 25, 2012 (the “Sublease”), whereby
Sublandlord leased to Subtenant approximately 37,481 rentable square feet consisting of the entire Sixth Floor of the Leased Premises (the “Original Subleased Premises”), upon and subject to the terms, covenants and
conditions herein contained. 
 WHEREAS, Sublandlord and Subtenant desire to enter into this Amendment for the purpose of evidencing their
mutual understanding and agreement regarding the expansion of the Original Subleased Premises and certain other matters relating thereto as set forth hereinbelow. 

NOW, THEREFORE, in consideration of the premises, the mutual covenants and terms contained herein, and other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 
 1. Defined Terms. All
terms used herein and denoted by their initial capitalization shall have the meanings set forth in the Sublease unless set forth herein to the contrary. 

2. Additional Subleased Premises. 

(a) Effective as of the later to occur of (i) June 1, 2014 or (ii) the date that Sublandlord receives Landlord’s written
consent to this Amendment (the “Expansion Date”), Sublandlord and Subtenant hereby agree that the Original Subleased Premises shall be expanded to include approximately 38,014 rentable square feet consisting of the entire
Fifth Floor of the Leased Premises as shown on the drawing attached hereto as Exhibit A and incorporated herein by reference (the “Additional Subleased Premises”; the Original Subleased Premises and the
Additional Subleased Premises are hereinafter collectively referred to as the “Subleased Premises”). Sublandlord has subleased and rented and does hereby sublease and rent to Subtenant, and Subtenant hereby subleases from
Sublandlord, effective as of the Expansion Date, the Additional Subleased Premises. Subtenant hereby subleases the Additional Subleased Premises upon the same terms and conditions as the Original Subleased Premises except as specifically set forth
herein to the contrary. The rentable area of the Additional Subleased Premises as specified in this Section 2 is only an approximation and no variation between the amount so stated and the actual rentable area of the Additional Subleased
Premises shall alter the obligations of Sublandlord and Subtenant under the Sublease, as amended hereby. 

  
 1 








 (b) On the Expansion Date, Sublandlord shall deliver the Additional Subleased Premises, and
Subtenant agrees to accept the Additional Subleased Premises, in its “as is” broom clean condition as of the date hereof and free of all occupants and personal property except as set forth on Exhibit B attached hereto.
Notwithstanding the forgoing, no later than ten (10) business days prior to the Expansion Date, Subtenant shall have the option to designate by written notice to Sublandlord any items listed on Exhibit B which Subtenant would like
removed. Except as expressly set forth above, Sublandlord shall not be obligated to perform any work or furnish any materials in, to or about the Subleased Premises in order to prepare the Additional Subleased Premises for use or occupancy by
Subtenant or otherwise. Subtenant agrees that in executing this Amendment, it has not relied upon any statements, representations, covenants or warranties made by Sublandlord or any person acting on behalf of Sublandlord other than those, if any,
expressly set forth in this Amendment, and on such investigations, examinations and inspections as Subtenant has chosen to make or has made. 

3. Term. The term of the Sublease with respect to the Additional Subleased Premises (“Additional Subleased Premises
Term”) shall commence on the Expansion Date and shall expire on the Expiration Date (as defined in the Sublease). 
 4.
Base Rent for Additional Subleased Premises. Commencing on the Expansion Date, Subtenant shall, in addition to the Base Rent described in the table in Section 4 of the Sublease, pay to Sublandlord additional Base Rent for
the Additional Subleased Premises as follows:

 5. Additional Rent for Additional Subleased Premises. In addition to the Base Rent for the
Additional Subleased Premises as set forth in Section 4 above, Subtenant covenants and agrees to pay, from and after the Expansion Date, the amounts specifically defined in Article 4.2 of the Master Lease as Operating Cost Escalation, as such
apply to the Additional Subleased Premises, except that (i) the Base Year for Operating Expenses shall be calendar year 2014 (ii) the Base Year Real Estate Taxes shall be fiscal year 2015 (i.e. July 1, 2014 to June 30, 2015) and
(iii) all charges set forth on Exhibit D to the Master Lease (specifically including electricity charges set forth in Section IX thereof). Sublandlord shall bill Subtenant for each item of Operating Cost Escalation promptly after Sublandlord
receives the corresponding bill from Landlord for items which were incurred or arose on and after the Expansion Date, and Subtenant shall pay each amount so billed within ten (10) business days after being billed therefore. 

  
 2 








 6. Security Deposit. 

(a) Sublandlord and Subtenant acknowledge that (i) Sublandlord is currently holding a security deposit of One Hundred Sixty-Five Thousand
Two Hundred Twenty Eight and 74/100 Dollars ($165,228.74) (the “Existing Security Deposit”). In connection with the Amendment, Subtenant shall pay to Sublandlord an additional security deposit equal to One Hundred Seventy-Six
Thousand and No/100 Dollars ($176,000.00) to further secure the performance of the Subtenant’s obligations under the Sublease (the “Additional Security Deposit”; the Existing Security Deposit and the Additional Security
Deposit are hereinafter collectively referred to as the “Security Deposit”). Provided that Subtenant is not in default under the Sublease or this Amendment beyond applicable notice and cure periods on the Additional Security
Deposit Reduction Date (as defined below), the required amount of the Additional Security Deposit shall be reduced to an amount equal to the sum of Eighty-Eight Thousand and No/100 Dollars ($88,000.00) on June 1, 2017 (the
“Additional Security Deposit Reduction Date”), and provided that Subtenant has provided the Additional Security Deposit, in cash, as opposed to a Letter of Credit (as set forth in Section 6(b) below), Sublandlord shall
promptly refund to Subtenant the applicable amount of such Security Deposit reductions on such dates. 
 (b) Notwithstanding the foregoing
provisions of Section 6(a) above, Subtenant may deliver the Additional Security Deposit to Sublandlord in the form of a letter of credit (the “Letter of Credit”), subject to the provisions of this Section 6(b). The
Letter of Credit shall name Sublandlord as its beneficiary and shall be transferable (without the payment of any fee), unconditional and irrevocable. The form and substance of the Letter of Credit and the identity of the issuing bank (the
“Issuer”) shall be satisfactory to Sublandlord in its sole discretion. The following provisions shall govern the Letter of Credit: 

(i) Subtenant shall be entitled to either provide a Letter of Credit providing for a term which expires on the Expiration Date or separate
Letters of Credit having earlier expiration dates. In the event Subtenant elects to provide separate Letters of Credit, Subtenant shall cause a replacement Letter of Credit meeting the requirements of this provision to be prepared, issued and
delivered to Sublandlord not less than thirty (30) days prior to the stated expiration of the Letter of Credit then being held by Sublandlord. In the event that Subtenant fails to deliver such replacement Letter of Credit to Sublandlord in a
timely manner, Sublandlord shall have the right, regardless of whether there then exists an default by Subtenant under the Sublease or this Amendment, to present the Letter of Credit to the Issuer for payment in which case any drawn funds shall be
held by Sublandlord as a security deposit by Sublandlord pursuant to the terms of Section 22 of the Sublease and Section 6(a) of this Amendment. 

(ii) Upon the occurrence of a default by Subtenant under the Sublease or this Amendment, Sublandlord shall be entitled to present the Letter
of Credit to the Issuer for payment; provided, however, if Sublandlord is prohibited by applicable law from giving Subtenant notice of a breach under the Sublease or this Amendment, Sublandlord shall still be entitled to present the Letter of Credit
to the Issuer for payment upon the occurrence of a breach or default under the Sublease or this Amendment. 
 (iii) Neither the Letter of
Credit nor its proceeds shall be considered a measure of Sublandlord’s damage in case of an default by Subtenant under the Sublease or this Amendment. After having presented the Letter of Credit to its issuer for payment, Sublandlord may, from
time to time in its sole discretion, without prejudice to any other right or remedy of Sublandlord, use the proceeds thereof to perform the obligation of Subtenant which was not performed and which resulted in


  
 3 








 
the default by Subtenant under the Sublease or this Amendment. Any sums remaining after any such expenditure by Sublandlord, shall be held as a security deposit by Sublandlord pursuant to the
terms of Section 22 of the Sublease and Section 6(a) of this Amendment. The presentment of the Letter of Credit to the Issuer for payment shall be cumulative of Sublandlord’s other rights and remedies available at law or in equity. No
failure or delay by Sublandlord in presenting the Letter of Credit to Sublandlord for payment shall constitute a waiver of any default by Subtenant under the Sublease or this Amendment. 

(iv) At the time of presentment of the Letter of Credit to the Issuer, Sublandlord shall provide the Issuer a certificate stating “The
undersigned representative of the Sublandlord pursuant to the terms of that certain Sublease agreement between Earthlink, LLC, as Sublandlord, and Demandware, Inc., as Subtenant, hereby certifies that the holder of this Letter of Credit is entitled
to present the Letter of Credit for payment.” The execution of this certificate is the only condition to the presentment of the Letter of Credit to the issuer for payment. 

7. Restoration of the Premises. The first grammatical sentence of Section 7(b) of the Sublease is hereby deleted in its
entirety and replaced with the following: 
 “Except as otherwise expressly provided in this Sublease, Subtenant assumes and shall keep,
observe and perform every term, provision, covenant and condition on Sublandlord’s part pertaining to the Subleased Premises which is required to be kept, observed and performed pursuant to the Master Lease and which arises or accrues during
the Term, specifically including, but not limited to, all of Sublandlord’s obligations to restore the Premises at the expiration of the Master Lease as set forth in Section 6.1.2 of the Master Lease.” 

8. Right of First Offer. Section 9 of the Sublease is hereby deleted in its entirety. 

9. Signage. Section 10 of the Sublease is hereby deleted in its entirety and replaced with the following: 

“Subject to the terms of the Master Lease, Subtenant shall have the right to maintain its existing signage rights as of the Effective Date
of the Amendment and all of Sublandlord’s signage rights under the Master Lease, including the signage rights set forth in Section 6.1.20 of the Master Lease; provided that Subtenant shall not have any right to the $25,000 allowance
provided in the second to last grammatical sentence of the second grammatical paragraph of Section 6.1.20. Notwithstanding anything to the foregoing contained in this Sublease, the provision of such signage is the sole responsibility of
Landlord, and not Sublandlord, subject to Sublandlord’s obligations under Section 14 below. As part of the process of assigning Sublandlord’s signage rights to Subtenant, Sublandlord shall remove the existing exterior signage of
Sublandlord as soon as practicable after obtaining Landlord’s consent pursuant to Section 14 below and shall use good faith, commercially reasonable efforts to remove such signage prior to the Expansion Date.” 

10. Brokerage. Sublandlord and Subtenant warrant and represent to the other that they have dealt with no real estate brokers,
finders, agents or salesmen in connection with this Amendment, except T3 Advisors (collectively, the “Broker”). Each party agrees to hold the other party harmless from and against all claims for brokerage commissions, finder’s
fees, or other compensation made by any other agent, broker, salesman or finder as a consequence of said party’s actions or dealings with any such agent, broker, salesman, or finder. Sublandlord agrees to pay Broker a brokerage commission
pursuant to a separate agreement. 

  
 4 








 11. Continued Validity. Except as hereinabove provided, all other terms and
conditions of the Sublease shall remain unchanged and in full force and effect, and are hereby ratified and confirmed by Sublandlord and Subtenant. Subtenant hereby acknowledges and agrees that, as of the date hereof, the Sublease is subject to no
offsets, claims, counterclaims or defenses of any nature whatsoever. 
 12. Binding Effect. This Amendment shall be governed
by and construed in accordance with the laws of the Commonwealth of Massachusetts, and shall be binding upon and inure to the benefit of the parties hereto and their respective heirs, successors, representatives and assigns, but always subject, in
the case of Subtenant, to the limitations on assignment and sublease set forth in the Sublease. In the event of any inconsistency or conflict between the terms of this Amendment and the terms of the Sublease, the terms hereof shall control. Time is
of the essence of all of the terms of this Amendment. 
 13. Modifications. This Amendment may not be changed, modified,
discharged or terminated orally in any manner other than by an agreement in writing signed by Sublandlord and Subtenant or their respective heirs, representatives, successors and permitted assigns.

	 	C.	Tenant agreed to sublease approximately 37,481 rentable square feet consisting of the entire sixth floor of the Premises (the “Sublease Premises”) to Subtenant as of the commencement date set forth in that

Agreement to induce Landlord to render such consent; and 

  

	 	G.	Landlord desires to consent to such exercise of Subtenant’s Right of First Offer under the Sublease, strictly in accordance with the terms and conditions of this Agreement. 








 NOW THEREFORE, in consideration of the promises herein contained, and other good and valuable
consideration, the receipt and sufficiency of which is hereby mutually acknowledged, the parties hereto agree as follows: 
 Agreement

 1. Capitalized Terms. Each capitalized term appearing but not defined herein shall have the meaning, if any, ascribed to

 EXHIBIT “A 

15. Termination of Master Lease. If the Master Lease shall be terminated for any reason, or Landlord shall accept a surrender of the
same, then, subject to the terms set forth in this Paragraph 15, the Sublease and the term and estate thereby granted shall terminate upon written notice from Landlord to Subtenant, and Subtenant shall vacate the Sublease Premises on the effective
date of such termination or surrender, unless the Master Lease is so being reinstated as provided below. Notwithstanding anything to the contrary contained in the Master Lease or the Sublease, in the event of the termination of the Master Lease
(including, without limitation, following rejection of the Master Lease in any bankruptcy or similar proceeding or following Tenant’s exercise of its termination right pursuant to Exhibit N of the Master Lease) or Master Landlord’s reentry
and repossession of the Premises prior to the expiration of the Term, the Master Landlord shall serve upon Subtenant written notice that the Master Lease has been terminated (or shall be terminated on a fixed date) together with a statement of any
and all sums which would at that time be due under the Master Lease but for such termination, and of all other defaults, if any, under the Master Lease. At Landlord’s election, exercisable by giving written notice to Subtenant simultaneously
with said notice from Landlord to Subtenant, Subtenant shall thereupon have the obligation to obtain a reinstatement of the Master Lease in accordance with and upon the following terms and conditions: 

(a) Upon the written request of Landlord requesting reinstatement of the Master Lease, within thirty (30) days after receipt of such
notice from Master Landlord that the Master Lease has been terminated or Master Landlord has reentered and repossessed the Premises, the Master Landlord shall reinstate the Master Lease of the entire Premises with Subtenant, whereupon Subtenant
shall cure any previously uncured defaults of Sublandlord under the Master Lease beyond applicable notice and cure periods which are reasonably susceptible of cure by Subtenant prior to the reinstatement of the Master Lease, and shall reimburse
Master Landlord for all of Master Landlord’s costs and expenses arising from Sublandlord’s defaults under the Master Lease, including, without limitation, Master Landlord’s reasonable attorneys fees. 

(b) Such reinstatement of the Master Lease shall be effective as of the date of termination of the Master Lease, and shall be for the
remainder of the Term (which shall include the right to exercise any applicable extension options subject to the terms and provisions of the Master Lease) and at the rent and upon all the agreements, terms, covenants and conditions thereof and
rental adjustments shall be made between the parties, as applicable. In addition to curing prior defaults of Sublandlord as provided in paragraph (a) above such reinstatement shall require Subtenant to perform any unfulfilled obligations of
Sublandlord under the Master Lease first arising, or continuing, after the event of default which occasioned the termination of the Master Lease. Upon the execution of such reinstatement of the Master Lease, Subtenant shall expressly assume in
writing all obligations as tenant under the Master Lease from and after the date thereof, including, without limitation, the obligation to pay any and all sums thereafter arising under the Master Lease.
