NOW, THEREFORE, the parties hereto, for themselves, their successors and assigns, mutually covenant and agree as follows: 

1. Capitalized Terms. Any capitalized terms used herein and not otherwise defined in this Sublease shall have the meanings ascribed
thereto in the Overlease. 
 2. Demise. Sublandlord does hereby sublease to Subtenant, and Subtenant does hereby sublease from
Sublandlord, the Sublet Premises for the Term and upon the conditions hereinafter provided, together with the right to use, on a non-exclusive basis and in common with other tenants, the common areas and facilities on the fourth floor and the other

(a) The “Term” of this Sublease shall commence on January 1, 2015, subject to the receipt by Sublandlord of the
Overlandlord’s written consent to this Sublease (the “Overlandlord Consent”) (the “Term Commencement Date”) and shall end on October 31, 2019, or on such earlier date upon which said Term may be terminated
in accordance with any of the conditions or limitations or other provisions of this Sublease (which date for the termination of the Term hereof shall hereafter be called the “Termination Date”). 







 (b) This Sublease, and the rights and obligations of Sublandlord and Subtenant under this
Sublease, are subject to the condition that Overlandlord consent to the subleasing of the Sublet Premises to the extent required under the Overlease, and this Sublease shall be effective only upon the receipt by Sublandlord of such consent and
provision of such consent by Sublandlord to Subtenant. Subtenant agrees to join such consent if so requested by Overlandlord in the form reasonably requested by Overlandlord. If the Overlandlord Consent is not obtained by January 15, 2015, then
either party may cancel this sublease by giving not less than fifteen (15) days written notice to the other party of its election to cancel, which cancellation shall be effective on the 15th
day following such notice if the Overlandlord Consent is not obtained prior to the end of such 15 day period. In the event this Sublease is cancelled as aforesaid, then this Sublease shall be null and void and neither party shall have any
further obligation to the other. 
 (c) Subtenant shall have one option (the “Extension Option”) to extend the term of this
Sublease for an additional twenty (20) month period (the “Extension Term”) on the same terms and conditions as this Sublease (other than Annual Base Rate and Monthly Base Rent, which shall be as set forth in
Section 3(b)(iv) below) subject, however, to the following conditions: 
 (i) Subtenant shall give written notice (“Extension
Notice”) to Sublandlord of its election to extend the Term at least nine (9) months, but no more than twelve (12) months, prior to the expiration of the Term;

this Sublease at the date of the Extension Notice or upon the commencement of the applicable Extension Term; 
 (iii) Subtenant’s
Extension Option is contingent upon Sublandord’s not exercising its right of first refusal to re-occupy the Sublet Premises (“Sublandlord ROFR”) upon the expiration of the Term. Sublandlord may elect to exercise the Sublandlord
ROFR by providing written notice to Subtenant within three months after its receipt of the Extension Notice (“Sublandlord Notice”), provided however that if Sublandlord does not provide the Sublandlord Notice to Subtenant within
three months after receipt of the Extension Notice from Subtenant, Sublandlord shall have waived its Sublandlord ROFR; and

Sublease, Attention: Controller, or such other place as Sublandlord may reasonably designate in advance in writing, in lawful money of the United States of America, without demand, deduction, offset or abatement. All sums owing by Subtenant to
Subleandlord under this Sublease other than Base Rent shall be deemed “Additional Rent”. Any installment of Base Rent or Additional Rent not paid when due may bear interest at the lesser of (a) a rate of twelve percent (12%) per
annum or (b) the highest rate permitted by law, from the date due until the date paid. 
 5. Operating Costs. Pursuant to
Section 4.2 of the Overlease, Sublandlord pays to Overlandlord its share of the amount by which Operating Costs exceed the Base Operating Costs for calendar year 2011 (other than real estate taxes which are included in Base Operating Costs
through the fiscal year ending June 30, 2012). In addition to Base Rent, Subtenant shall pay to Sublandlord, as additional rent under this Sublease, Subtenant’s Proportionate Share of (i) real estate taxes above a 2015 Base Year, and
(ii) Operating Expenses above a 2015 Base Year (collectively, the “Operating Cost Escalation”). Sublandlord shall bill Subtenant for the Operating Cost Escalation promptly after Sublandlord receives the corresponding bill from the
Overlandlord and Subtenant shall pay each amount so billed within ten (10) business days after its receipt of such invoice., provided, however, that if Tenant is required to make estimated payments pursuant to Section 4.2 of the Overlease,
then Subtenant shall make estimated payments of such amounts monthly, in advance, at the time and in the matter provided in Section 

  
 3 








 
4.2 of the Overlease. “Subtenant’s Proportionate Share” shall be 12.93%, based on the rentable area of the Sublet Premises divided by the rentable area of the Premises. 

6. Electricity. Commencing on the Term Commencement Date, Subtenant shall pay to Sublandlord the sum of $1,206 prior to the first day
of each month in the Term in respect of electrical services to the Sublet Premises as estimated by Sublandlord on a $1.50 per square foot basis. Sublandlord assumes that Subtenant’s usage will be typical of tenants of Class A office space
and Sublandlord reserves the right to install, at its expense, a sub-meter and thereafter bill Subtenant for actual usage, in which case Sublandlord shall promptly notify Subtenant of such sub-metering and on a monthly basis any amounts determined
thereby, and Subtenant shall have thirty (30) days within which to make such payments as additional rent hereunder. 
 7. Security
Deposit. Simultaneously with the execution of this Sublease, Subtenant shall pay to and deposit with Sublandlord the sum of $25,000 (the “Security Deposit”). Sublandlord shall hold the Security Deposit throughout the term of
this Sublease as security for the performance by Subtenant of all obligations on the part of Subtenant hereunder. The Security Deposit shall not be deemed an advance rent deposit or an advance payment of any other kind, or a measure or limitation of
Sublandlord’s damages or constitute a bar or defense to any of Sublandlord’s other remedies under this Sublease or at law or in equity upon Subtenant’s default. Sublandlord shall have the right from time to time, without prejudice to
any other remedy Sublandlord may have on account thereof, to apply such deposit, or any part thereof, to Sublandlord’s damages arising from, or to cure, any default of Subtenant. If Sublandlord shall so apply any or all of the Security Deposit,
Subtenant shall within ten (10) days after written demand from Sublandlord deposit with Sublandlord the amount so applied to replenish the Security Deposit. Sublandlord shall return the Security Deposit, or so much thereof as shall not have
theretofore been applied in accordance with the terms of this Section 7, to Subtenant on the expiration or earlier termination of the Term of this Sublease and surrender of possession of the Sublet Premises by Subtenant to Sublandlord at such
time, provided that if there is then existing a default (or any circumstance which, with the passage of time or the giving of notice, or both, would constitute a default), Sublandlord shall retain a portion of the Security Deposit sufficient to cure
such default and shall return the remainder of the Security Deposit to Subtenant within thirty (30) days after the Termination Date. While Sublandlord holds the Security Deposit, Sublandlord shall have no obligation to pay interest on the same
and shall have the right to commingle the same with Sublandlord’s other funds. If Sublandlord conveys Sublandlord’s interest under this Sublease, the Security Deposit, or any part thereof not previously applied, shall be turned over by
Sublandlord to Sublandlord’s grantee, and, if so turned over, Subtenant agrees to look solely to such grantee for proper application of the Security Deposit in accordance with the terms of this Section 7, and the return thereof in
accordance herewith. 
 8. Use. Subtenant shall use and occupy the Sublet Premises only for the use permitted under the Overlease
(the “Permitted Uses”). Subtenant shall also comply with all laws governing or affecting Subtenant’s use of the Sublet Premises, and Subtenant acknowledges that Sublandlord has made no representations or warranties concerning whether
the Permitted Uses comply with such laws. 
 9. Surrender. Upon the expiration or earlier termination of this Sublease, Subtenant
shall vacate and deliver the Sublet Premises to Sublandlord in vacant, broom clean condition and 

  
 4 








 
otherwise in the condition required under Section 6.1.2 of the Overlease, as incorporated herein by reference with the Furniture in place in accordance with Section 30. 

10. Insurance. Subtenant shall obtain and maintain all insurance types and coverage as specified in the Overlease to be obtained and
maintained by Sublandlord, as tenant, in amounts not less than those specified in the Overlease. All such policies of insurance shall name Overlandlord and Sublandlord as additional insureds thereunder. Subtenant’s insurance shall be primary
over Overlandlord’s and Sublandlord’s insurance. 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. 
 11. Enforcement of Overlease. (a) Subtenant shall neither do nor permit anything to be done which would cause a
default under the Overlease which default remains uncured beyond any applicable cure period, or termination or forfeiture by reason of any right of termination or forfeiture, reserved or vested in the Overlandlord under the Overlease and Subtenant
shall indemnify and hold Sublandlord harmless solely (but not in limitation of Section 12 of this Sublease) from and against all claims of any kind whatsoever by reason of breach or default on the part of Subtenant, or termination or forfeiture
which is the consequence of any such breach or default. 
 (b) Sublandlord hereby acknowledges and agrees 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 Overlease. Upon the written request of Subtenant, Sublandlord shall use reasonable efforts
(but shall have no obligation to bring a formal action or proceeding), at Subtenant’s sole cost and expense, to enforce on behalf of Subtenant, Sublandlord’s rights under the Overlease with respect to the Sublet Premises. Subtenant shall
also have the right to take such action in its own name. If (i) any such action against the Overlandlord in Subtenant’s name is barred by reason of lack of privity, non-assignability or otherwise,
and (ii) the failure of Overlandlord to perform its obligations under the Overlease would have a material adverse effect upon the Sublet 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 (A) the same is without cost and expense to Sublandlord, (B) Subtenant shall provide the
indemnification to Sublandlord required pursuant to its obligations under the Overlease, and (C) Subtenant is not in default hereunder. 

(c) Provided Subtenant is not in default under this Sublease (subject to applicable notice and cure periods), Sublandlord covenants that it
shall not voluntarily cancel or surrender the Overlease (except the foregoing shall not apply to Sublandlord’s termination rights in the event of a casualty or condemnation, nor shall Sublandlord be obligated to exercise any extension option
under the Overlease), nor consent to any modification, amendment or supplement to the Overlease which materially, adversely impacts Subtenant, without the prior written consent of Subtenant. If the Overlease 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 

  
 5 








 
any manner whatsoever for such termination. Sublandlord shall promptly forward to Subtenant any default or termination notice with respect to the Overlease received by Sublandlord and this
Sublease shall terminate in the event of any such termination of the Overlease. A termination of the Overlease 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 Overlease under this Section. 
 12. Subordination to Overlease. (a) This Sublease is subject
and subordinate to the terms and conditions of the Overlease as applicable to the Sublet Premises and Sublandlord does not purport to convey, and Subtenant does not hereby take, any greater rights in the Sublease Premises than those accorded to or
taken by Sublandlord as tenant under the Overlease. 
 (b) Except as expressly otherwise provided in this Sublease, all of the terms,
provisions, covenants and conditions of the Overlease are incorporated herein by reference and hereby made a part of this Sublease. However, for purposes of such incorporation by reference, all references to Landlord and Tenant shall be deemed
references to Sublandlord and Subtenant, respectively, all references to the Premises shall be deemed references to the Sublet Premises and all references to the term of the Overlease shall be deemed references to the term of this Sublease, 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 Term Commencement Date. In the event of a conflict or ambiguity between the
provisions of the Overlease and the provisions of this Sublease, the provisions of this Sublease shall govern and control. Subtenant shall be entitled to the same notice and cure periods, less five (5) business days, as Sublandlord is afforded
pursuant to Section 9.1 of the Overlease. Sublandlord shall have all of the rights and remedies of the Overlandlord under the Overlease as against Subtenant and, as between the parties hereto, Subtenant agrees to observe and perform all of the
terms, covenants and conditions on Sublandlord’s part to be observed and performed under the Overlease as applicable to the Sublet Premises as incorporated herein by reference. 

13. Overlandlord’s Services and Obligations under the Overlease. Notwithstanding anything in this Sublease or the Overlease to the
contrary, including without limitation Section 11 hereof and Article 5 and Exhibit D of the Overlease, Subtenant agrees that (i) Sublandlord shall have no obligations under this Sublease to perform the obligations of Overlandlord, as
landlord under the Overlease, including, without limitation, any obligation to provide services, perform maintenance or repairs, or maintain insurance, and Subtenant shall seek such performance and obtain such services solely from the Overlandlord;
(ii) Sublandlord shall not be bound by any representations or warranties of the Overlandlord under the Overlease; (iii) in any instance where the consent of Overlandlord is required under the terms of the Overlease, the consent of
Sublandlord and Overlandlord shall be required; and (iv) Sublandlord shall not be liable to Subtenant for any failure or delay in Overlandlord’s performance of its obligations, as landlord under the Overlease, nor shall Subtenant be
entitled to terminate this Sublease or abate the Base Rent or Additional Rent due hereunder except to the extent Sublandlord is permitted to abate rent or terminate under the Overlease. Upon the written request of Subtenant, Sublandlord shall use
reasonable efforts to cause the Overlandlord to observe and/or perform the obligations of the Overlandlord under the Overlease which relate to the Sublet Premises; provided, however, that Sublandlord shall not be required to incur any


  
 6 








 
expense or expend any sums to obtain such enforcement, except to the extent of funds advanced by Subtenant to Sublandlord for such purpose. 

14. Certain Overlease Provisions Not Incorporated. The following provisions of the Overlease are expressly not incorporated into
this Sublease: Reference Data, Sections 2.1, 2.2, 3.1, 3.2, 3.5 and 3.6, Article 4, Section 5.1, Section 6.1.6, the provisions regarding Alterations costing less than $50,000 in Section 6.1.15, the second and third paragraphs of
Section 6.1.20, Section 10.2, Section 10.4, Section 10.14, Section 10.19, Article 11, and all Exhibits (except Exhibit E); as well as such other terms of the Overlease as do not relate to the Sublet Premises or are
inapplicable, inconsistent with, or specifically modified by, the terms of this Sublease. In furtherance of the foregoing, Subtenant shall not take any action or do or permit to be done anything which (A) is or may be prohibited as to
Sublandlord under the Overlease, (B) would result in a default under any of the provisions of the Overlease, provided that Subtenant has received notice and a reasonable opportunity to cure such default, or (C) would result in any
additional cost or liability to Sublandlord. Subtenant acknowledges that it has reviewed the Overlease attached hereto and made a part hereof as Exhibit B, and that it is familiar with the contents thereof. 

15. Alterations and Improvements. Subtenant shall not perform any Alterations (as defined in the Overlease) without Sublandlord’s
prior consent, which shall not be unreasonably withheld, conditioned or delayed (provided that a requirement by Sublandlord that such Alterations be removed and the Sublet Premises restored at the end of the Term by Subtenant at Subtenant’s
cost shall not be considered an unreasonable condition), subject to the applicable terms and conditions of the Overlease (except that the provisions regarding Alterations permitted without consent shall not be applicable) and receipt of required
approvals from Overlandlord for such improvements. Nothing in this Sublease shall be construed as an agreement that Sublandlord has any obligation to perform any alterations, installments, removals, additions or improvements for Subtenant whatsoever
and the Sublet Premises shall be provided and delivered in “as is” broom swept condition. To the extent permitted in the Overlease and subject to the provisions thereof (including the obligation to remove the same at the termination of
this Sublease to the extent required by the Overlease or Overlandlord), Subtenant shall have the right to perform modifications to the Sublet Premises, including in particular, installation of an enterprise data network and security equipment and
hardware. Any improvements will be paid by Subtenant and are subject to both Sublandlord’s and Overlandlord’s reasonable approval rights, not to be unreasonably withheld, conditioned or delayed in the case of Sublandlord (provided that a
requirement by Sublandlord that such Alterations be removed and the Sublet Premises restored at the end of the Term by Subtenant at Subtenant’s cost shall not be considered an unreasonable condition). 

16. Assigning and Subletting. Notwithstanding any provision of the Overlease incorporated herein to the contrary, Subtenant shall not
assign, mortgage, transfer (by operation of law or otherwise), or hypothecate this Sublease or sublet, license or permit and other party to use or occupy any portion of the Sublet Premises (individually, a “Transfer”) except, to the
extent permitted by Overlease, to any related 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 without the prior written consent of Sublandlord and 

  
 7 








 
Overlandlord, which they may grant, withhold or condition in their respective sole discretion. The following transactions shall be deemed assignments of this Sublease requiring such prior written
consent: (i) any assignment, mortgage, pledge or other transfer of this Sublease; (ii) any sublease, license or occupancy agreement with respect to any portion of the Sublet Premises. If Sublandlord and Overlandlord consent to any such
Transfer, such Transfer shall comply with the requirements of Section 6.1.6 of the Overlease and Subtenant shall pay over to Sublandlord 50% of the excess of such amounts payable each month in connection with a Transfer to the extent in excess
of the Rent due to Sublandlord hereunder. Overlandlord’s refusal to consent to a Transfer shall be deemed a reasonable reason for Sublandlord to withhold its consent to a Transfer, without any obligation on the part of Sublandlord to dispute
Overlandlord’s refusal. Nothing contained herein shall be deemed to limit or amend the rights of Overlandlord under Section 6.1.6 of the Overlease. Any attempt by Subtenant to Transfer the Sublet Premises or the Sublease without the prior
written consent of both Sublandlord and Overlandlord shall be void. No consent by the Sublandlord pursuant to this Section shall be deemed a waiver of the obligation to obtain the Sublandlord’s consent to a Transfer on any subsequent occasion;
no waiver of the foregoing restrictions or any portion thereof to a Transfer shall constitute a waiver or consent in any other instance; and Subtenant shall remain at all times primarily liable for the performance and payment of all terms,
conditions, covenants and agreements contained herein. 
 17. Representations and Warranties. 

Sublandlord represents and warrants to Subtenant as follows as of the date of execution and delivery of this Sublease: (i) to
Subtenant’s knowledge, the Overlease is in full force and effect in accordance with, and subject to, all of the terms, covenants, conditions and agreements contained therein; (ii) the Overlease has not been modified, amended or
supplemented except as set forth on Exhibit B; (iii) Sublandlord has not received any notice of any default by the Sublandlord under the Overlease, which default remains uncured, and is not aware of, any material default by the Sublandlord
under the Overlease, which default remains uncured; (iv) Sublandlord holds the entire tenant’s interest in the Sublet Premises under the Overlease free and clear of any liens, claims, mortgages, charges or encumbrances, subleases and
occupancies (other than this Sublease and the Overlease), other than matters to which the tenancy of the Sublandlord, as tenant under the Overlease, is or may be subordinate; and (v) subject to receipt of approval of Overlandlord to this
Sublease, Sublandlord has full right, power and authority to enter into this Sublease. 
 (c) Each party acknowledges and agrees that it has
not received or been offered any illegal bribe, kickback, payment, gift or thing of value from any employee, agent or representative of the other party in connection with this Sublease, other than reasonable gifts and entertainment provided in the
ordinary course of business. Each party will promptly notify the other party if it offers or receives any such improper payment or transfer in connection with this Sublease. 

18. Notice. Any and all communications delivered hereunder shall be in writing and delivered or served in accordance with Article 14.5
of the Overlease addressed as follows: if to Overlandlord: as provided in the Overlease; if to Sublandlord, at the Premises, to the attention of Jonathan Moulton, General Counsel; and if to Subtenant, at the Sublet Premises, to the attention


  
 8 








 
of Chief Legal Officer, or to such other address and attention as any of the above shall notify the others in writing. 

19. Default. In the event of a default by Subtenant in the full and timely performance of its obligations under the Sublease,
including, without limitation, its obligation to pay Base Rent or Additional Rent, Sublandlord shall have all of the rights and remedies available to “Landlord” under the Overlease as though Sublandlord were “Landlord” and
Subtenant were “Tenant”, including without limitation the rights and remedies set forth in Sections 9.1 and 9.2 of the Overlease. The foregoing shall survive the expiration or early termination of this Sublease. 

20. Successors and Assigns. This Sublease and everything herein contained shall extend to and bind and inure to the benefit of the
Sublandlord and its successors and assigns and the Subtenant and its permitted successors and assigns. No rights shall inure to the benefit of any assignee, subtenant or occupant unless the provisions of Section 6.1.6 of the Overlease and
Section 16 of this Sublease are complied with. 
 21. Miscellaneous. Neither Sublandlord nor any agent or representative of
Sublandlord has made or is making, and Subtenant in executing and delivering this Sublease is not relying upon, any warranties, representations, promises or statements whatsoever, except to the extent expressly set forth in this Sublease. All
understandings and agreements regarding the subject of this Sublease, if any, heretofore had between the parties are merged into this Sublease, which alone fully and completely expresses the agreement of the parties. No surrender of possession of
the Sublet Premises or of any part thereof or of any remainder of the term of this Sublease shall release Subtenant from any of its obligations hereunder unless accepted by Sublandlord in writing. 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. The receipt and retention by Sublandlord of Base Rent or additional rent from anyone other than Subtenant shall not be deemed a waiver of the breach by Subtenant of any
covenant, agreement, term or provision of this Sublease, or as the acceptance of such other person as a tenant, or as a release of Subtenant from the covenants, agreements, terms, provisions and conditions herein contained. The receipt and retention
by Sublandlord of Base Rent or additional rent with knowledge of the breach of any covenant, agreement, term, provision or condition herein contained shall not be deemed a waiver of such breach. This Sublease shall be governed by, and construed in
accordance with the laws of The Commonwealth of Massachusetts. All of the terms and provisions of this Sublease shall be binding upon and inure to the benefit of the parties hereto and their respective permitted successors and assigns. This Sublease
may not be amended, modified or terminated, in whole or in part, nor may any of the provisions be waived, except by a written instrument executed by the party against whom enforcement of such amendment, modification, termination or waiver is sought.
This Sublease may be executed in any number of counterparts, each of which counterparts shall be deemed to be an original, and all of which together shall constitute one and the same instrument.

 22. Quiet Enjoyment. So long as Subtenant is not in default under this Sublease, its quiet
enjoyment of the Sublet Premises shall not be disturbed or interfered with by Sublandlord or anyone claiming by, through or under Sublandlord. 

23. Overlandlord’s Consent. It is hereby acknowledged by Sublandlord and Subtenant that Overlandlord’s consent to this
Sublease shall not create any contractual liability or duty on the part of Overlandlord or its agent to the Subtenant, and shall not in any manner increase, decrease or otherwise affect the rights and obligations of Overlandlord and Sublandlord, as
the lessee under the Overlease, with respect to the Sublet Premises. 
 24. Sublandlord’s Consent. Whenever Sublandlord’s
consent is required under this Sublease, Sublandlord’s rejection of a request made by Subtenant shall not deemed unreasonable, in any case, if such rejection is based on Overlandlord’s rejection of such request.

and Jones Long LaSalle in connection with this Sublease for the Sublet Premises. Each party shall 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. 

26. Termination of Overlease. In the event of a default under the Overlease by Sublandlord that results in the termination of the
Overlease, Subtenant shall, at the option of Overlandlord, provided in writing to Subtenant (to the extent required by the Overlease), attorn to and recognize Overlandlord as Sublandlord hereunder and shall, promptly upon Overlandlord’s written

Tenant shall have, as appurtenant to the Premises, the right to use in common with others entitled thereto, subject to reasonable rules of
general applicability to tenants of the Building from time to time made by Landlord of which Tenant is given notice: (a) the common areas and facilities included in the Building or on the parcel of land on which the Building is located
(“the Lot”), including, without limitation, a fitness center, locker rooms and a cafe located within the Building, and the common areas and facilities included within Burlington Office Park I (the “Park”), and all means of access

sidewalks, roads, driveways and the like, to the extent all of the foregoing are from time to time designated by Landlord; and (b) the Building service fixtures and equipment and the common
mechanical or electrical closets and shafts, ducts and conduits serving the Premises. Landlord represents and warrants that the parking ratio available for the Building is 3.8 parking spaces per 1,000 RSF and that in the event that any excess spaces
above that ratio provided to other tenants of the Building as of the date of this Lease are no longer provided to such tenant, Tenant shall have the right to use such spaces, up to a total allocation of 3.8 spaces per 1,000 RSF. 

Landlord reserves the right from time to time, without unreasonable interference with Tenant’s use (a) to install, repair, replace,
use, maintain and relocate for service to the Premises and to other parts of the Building or either, building service fixtures and equipment wherever located in the Building, and (b) to alter or relocate any other common area or facility,
provided that substitutions are substantially equivalent or better. Landlord’s exercise of the foregoing rights shall not materially increase Tenant’s obligations or diminish Tenant’s rights hereunder, or materially interfere with
Tenant’s parking rights. 
 Subject to the provisions hereinafter provided, Tenant shall have the appurtenant right, at no additional
charge, to place dedicated equipment, including without limitation, a dedicated emergency generator and any other associated equipment, wiring, shaft space, etc. required in connection therewith and to all Codes (as hereinafter defined) on the roof

thereof, shall be borne by Tenant. The size, the type of equipment and the precise location of the installation shall be pre-approved by Landlord, which such approval shall not be unreasonably withheld, conditioned or delayed by Landlord. All
installations shall be in accordance with sound construction practices, and in accordance with all applicable Codes, 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 equipment so installed by Tenant
hereunder, including the generator (as applicable), 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 (or installation thereof, if later). 

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 equipment so installed by Tenant hereunder, including the generator (as applicable) and any other associated equipment.
Upon expiration of the Term, Tenant shall be responsible for the removal of the same and for repairing any damage caused therefrom. These provisions shall survive the expiration or earlier termination of this Lease.

electrical, lighting, flooring and doors and hardware. Tenant shall permit Landlord to review and provide input during the preparation of Tenant’s Plans and shall provide Landlord with preliminary plans and specifications as they are made
available to Tenant by its architect. Upon receipt, Landlord shall have ten (10) days to comment upon the Tenant’s Plans 

  
 6 








 
and shall be deemed approved in the event that Landlord 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. 
 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. Landlord will not approve
Tenant’s Plans (or changes to Tenant’s Plans) which involve any non-standard office 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 re-adaptation 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 Tenant and revised sets
of Tenant’s Plans shall be forthwith furnished to Landlord upon Tenant’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 Tenant and revised sets of Tenant’s Plans shall be forthwith furnished to Landlord upon
Tenant’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 and Landlord’s prior consent, such consent not to be unreasonably withheld or delayed by Tenant or Landlord, as applicable. 

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 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 fifty percent (50%) of the actual Cost of Change Order(s), less credits for any Tenant’s Work deleted, but including a contractor’s fee of five percent (5%) and overhead of five percent
(5%) of the aggregate costs, within fourteen (14) business days of receipt of Landlord’s invoice therefor, with any remaining amount to be delivered to Landlord within thirty (30) days after receipt of a


  
 7 








 
final accounting from Landlord following delivery of the Premises and completion of the Punch List Items. 

In the event that Tenant approves 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 a Tenant Delay shall be deemed to have occurred for the 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 provide Tenant with written notice of such determination at the time it submits the Change
Order to Tenant for approval, 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, and Tenant shall have no obligation to restore the Tenant’s Work Premises at the end of the Term or earlier expiration thereof, except for Tenant’s business fixtures, equipment and personal property, 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 time 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, subject to Section 10.13. 
 Tenant (including its contractors, agents or employees) shall have access to
the Premises, from time to time prior to the Scheduled Term Commencement Date, 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 an allowance of up
to $6.00/RSF to be used for Tenant’s furniture, fixtures and equipment. Such allowance shall be paid by Landlord to Tenant (or its vendor or contractor, as applicable) within fourteen (14) days of Landlord’s receipt of an invoice
therefor, which such invoice shall contain such reasonable documentation as may reasonably be 

  
 8 








 
requested by Landlord. In addition, Exhibit C designates certain “Tenant Change Items” which Tenant shall have the right, exercisable by a written notice to Landlord given prior to
February 15, 2011, to accept or reject. In the event that any such items are accepted by Tenant, then Tenant shall reimburse Landlord said costs allocable to such accepted item (as described on said Exhibit C) within fourteen (14) business
days of receipt of Landlord’s invoice therefor. 
 At Tenant’s election, exercisable by giving Landlord written notice on or
before December 31, 2011, Landlord shall provide an additional allowance of up to $5.00/RSF to be used for tenant improvements, tel/data, security, furniture, fixtures or equipment, which such allowance-shall be amortized over the Term at an
annual rate of seven percent (7%) per annum, In the event that Tenant elects to receive such additional allowance, then Landlord and Tenant shall enter into a mutually agreeable amendment to this Lease modifying the Fixed Rent set forth in
Section 1.1 hereof. 
  

	3.2	PREPARATION OF PREMISES FOR OCCUPANCY 

 Landlord agrees 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 (excluding typical periods for obtaining
permits and approvals for the Landlord’s Work), unusual scarcity of or inability to obtain labor or materials, labor difficulties not specifically related to Landlord or GCCI), casualty or other causes reasonably beyond Landlord’s control
(each, a “Force Majeure Delay”), or any Tenant Delay (as hereinafter defined), provided that such extension shall only be available to the extent that Landlord promptly notifies Tenant of the occurrence of any Force Majeure Delay or Tenant
Delay. For purposes of this Lease, a “Tenant Delay” shall mean any one of the following: (i) Tenant Alteration Delay Days; (ii) Tenant’s failure to supply information as reasonably requested by Landlord within the time
periods specified herein (or if no time period is specified, within five (5) business days of request) in order to complete construction in a timely manner, (iii) Tenant’s failure to deliver the Tenant’s Plans (or modifications
or said long lead item information) within the time periods specified herein, or (iv) a written request of Tenant to stop work. The Premises shall be deemed ready for occupancy (“Ready for Occupancy”) on the date on which all of the
following have occurred: (x) the Landlord’s Work is completed in compliance with the approved Tenant Plans therefor, as certified in good faith by Landlord’s architect, except for punch list items relating to Tenant’s Work which
do not exceed five percent of the total costs of Landlord’s Work and do not interfere with Tenant’s use of the Premises for its operation (“Punch List Items”), and Landlord has obtained a Certificate of Occupancy (which, if
temporary, shall be only subject to agreed upon Punch List Items and any items of work for which Tenant is responsible hereunder) for the Premises and has provided Tenant with a copy thereof; provided, however, that if Landlord is unable to complete
construction (other than Punch List Items) by the Scheduled Term Commencement Date solely due to any Tenant Delay, then notwithstanding any language to the contrary set forth herein and solely for purposes of determining the Commencement Date (and
subsequent time periods, and/or actions that are triggered by the occurrence of the Commencement Date, as applicable), the Premises shall be deemed “Ready for Occupancy” on 

  
 9 








 
the date the Premises would have been completed (other than Punch List Items), but for a Tenant Delay, subject to Tenant’s right to dispute the same as hereinafter provided, and it being
agreed that such deemed occurrence shall not relieve Landlord from the obligation to diligently pursue the Landlord’s Work to completion; and (y) all approvals and permits from the appropriate governmental authorities required for the
legal occupancy of the Premises have been obtained. Landlord shall complete all Punch List Items within thirty (30) days of the date the Premises are Ready for Occupancy. 

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. In addition, if the Premises are not deemed Ready for Occupancy on or before the later of August 1, 2011 or 30 days following Scheduled Term Commencement for whatever reason other than a Force Majeure
Delay or Tenant Delay (the “Rent Credit Deadline”), then Tenant shall receive a credit of one day of Fixed Rent for each day after the Rent Credit Deadline until the Premises are Ready for Occupancy, but if such period exceeds thirty
(30) days, then such credit shall increase to two days of Fixed Rent for each day thereafter until the Premises are Ready for Occupancy, such credits to be applied when the Fixed Rent commences hereunder. 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 ninety (90) days following the
Scheduled Term Commencement Date 
 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 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 

  
 10 








 
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 Punch List Items. 
  

	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 (or such longer period as such work or materials
may be under warranty). 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


  
 11 








 
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 the aforesaid one (1) year period. 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 (Including repairs due to late 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. 
 ARTICLE 4
 
 RENT 
  

	4.1	RENT 

 Tenant agrees to pay, without any offset or reduction whatever (except as
expressly set forth herein), Fixed Rent equal to 1/12th of the annual Fixed Rent (i.e. the Monthly 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 prorated based on the number of days of the Term falling within such calendar month. 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 and electricity pursuant to Exhibit “D”, Paragraph IX of Exhibit “D”).

  

	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). Within ninety (90) days 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 (as defined herein). Landlord Operating Costs shall mean the commercially reasonable costs incurred by Landlord in operating, cleaning, maintaining, managing, and repairing the Building and the Lot, 

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; 

  
 12 








 BUT INCLUDING, without limitation: real estate taxes on the Building and Lot; installments on
assessments for public betterments or public improvements but only to the extent of the installment required to be paid in such Fiscal Year, Landlord hereby agreeing to pay such amounts over the longest period available under applicable law,
reasonable expenses of any proceedings for abatement of taxes and assessments with respect to any Fiscal Year or fraction of a Fiscal Year; reasonable premiums for insurance; reasonable compensation and all reasonable fringe benefits for full- time
employees at the Building, workmen’s compensation, insurance premiums and payroll taxes paid by Landlord to/for or with respect to all persons engaged in the operating, maintaining, managing or cleaning of the Building and Lot, water, sewer,
gas, telephone and the electricity to operate the base building heating, ventilating, air conditioning systems, elevators and parking lot lighting, and other utility charges not billed directly to tenants by Landlord or the utility companies (the
cost for the electricity consumed by the tenant for interior lighting, plugs, equipment, supplemental air conditioning and fixtures in shall be billed monthly to Tenant by Landlord as set forth in Paragraph IX of Exhibit “D”);
measurable and market costs of building and cleaning supplies and equipment (including rental); reasonable cost of maintenance, cleaning and repairs, including without limitation the services provided in Exhibit “D” hereof; cost of snow
plowing or removal, or both, and care of landscaping; payments to independent contractors under service contracts for cleaning, operating, managing, maintaining and repairing the Building and Lot (which payments may be to affiliates of Landlord
provided the same are at reasonable rates consistent with the type of occupancy and the services rendered); the Building’s pro rata share (i.e. approximately 39.45% as hereinafter provided) of the Park-related costs (as defined below,
including, but not limited to, snow plowing, sanding, sand removal, lot sweeping, landscaping, and common area and street lighting); and all other reasonable and necessary expenses paid in connection with the operation, cleaning, maintenance,
management, and repair of the Building (including the cafeteria and fitness center located therein) 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, 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) on the unamortized amount, shall be included in “Landlord’s Operating Costs”, but with respect to subsection (i) in no event may the amount included herein with respect to a Fiscal Year exceed the reasonably
projected annual reduction in 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 by Landlord at commercially reasonable, competitive market rates consistent
with the operation and management of comparable Class A office buildings in the suburban Boston area. 
 Notwithstanding the foregoing,
in no event shall “controllable operating expenses” included within Landlord’s Operating Costs increase by more than five percent (5%) per Lease Year, on a cumulative basis. For purposes hereof, the term “controllable
operating expenses” shall mean those Operating Costs within Landlord’s control, exercising prudent business 

  
 13

	 	(bb)	any cost arising from Landlord’s charitable or political contributions; and 

  

	 	(cc)	any other expenses which, in accordance with generally accepted accounting principles, consistently applied, would not customarily be treated as Operating Costs by lessors of comparable buildings. 


In the event that the average occupancy rate for the Building is less than ninety-five (95%) percent for any Fiscal Year (including
Fiscal Year 2011), then for purposes of calculating Operating Costs, the Operating Costs for such Fiscal Year shall be increased by the additional costs and expenses that Landlord reasonably and in good faith estimates would have been incurred if
the average occupancy rate had been ninety-five (95%) percent for such Fiscal Year. It is not the intent of this provision to permit Landlord to charge Tenant for any Operating Costs attributable to unoccupied space, or to seek reimbursement
from Tenant for costs Landlord never incurred. Rather, the intent of this provision is to allow Landlord to recover only those increases in Operating Costs properly attributable to occupied space in the Building and this provision is designed to
calculate the actual cost of providing a variable operating expense service to the portions of the Building receiving such service. This “gross-up” treatment shall be applied only with respect to Operating Costs which vary based on
level of occupancy. 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 the Operating Cost Escalation based


  
 16 








 
upon the proportion that the Rentable Floor Area of Tenant’s Space bears to the Total Rentable Floor Area of the Building (i.e. 26.85%), but any elements of Operating Costs which relate to
elements of the Park other than the Building and the Lot (“Park-related costs”), shall be allocated by Landlord in a commercially reasonable manner 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%). In no event shall
Park-related costs include costs which do not relate to a service or amenity which has a benefit to the Building or which relate exclusively to another Building or Lot in the Park. 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

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

  

	 	(a)	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 


 

	 	(b)	the product of the Base Operating Costs 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 1/12th 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 pay during a Fiscal Year because of or in connection with the ownership, leasing and operation of the Lot, the Building and


  
 17 








 
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 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. 

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 reasonable costs incurred by Landlord in obtaining such rebate or abatement (unless previously included in Operating Costs for such year), 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. 

  
 18 








 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 eighty (180) 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 $5,000.00), then Landlord shall pay the reasonable cost of such audit (not to exceed $5,000.00). 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 and no such change may
result in Tenant paying any more hereunder that would have been due from Tenant in the absence of such change. 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 Statement, and appropriate adjustment shall be made according thereto. All Landlord’s Statements shall be prepared on an accrual basis of accounting. 

  
 19 








 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 for a period of one year. 
  

	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 rate equal to twelve percent (12%) per annum 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) business days per each calendar year of the Term before which such interest shall be charged by Landlord.

	5.2	INTERRUPTIONS 

 Except to the extent caused by, or arising out of, the negligence or

arising from power losses or shortages or from the necessity of Landlord’s entering the Premises for any of the purposes in this Lease authorized, or for repairing the Premises or any portion of the Building or Lot. In case Landlord is
prevented or delayed from making any repairs, alterations or improvements, or furnishing any service or performing any other covenant or duty to be performed on Landlord’s part, by reason of any cause reasonably beyond Landlord’s control,
Landlord shall not be liable to Tenant therefore, nor, except as expressly otherwise provided below or in Article 7, shall Tenant be entitled to any abatement or reduction of rent by reason thereof. 

Notwithstanding any terms of this Lease to the contrary, if any Building service is interrupted for a period of four (4) business days
due to the negligence or willful acts of Landlord, its agents, servants, employees, contractors or subcontractors (and not due to acts or failure to act by Tenant, its agents, servants, employees, contractors or subcontractors), and such failure
adversely and materially effects Tenant’s use of the Premises for Tenant’s normal business operations, then there shall be an abatement on a square footage prorata basis of Fixed Rent and additional rent from and after said time period,

 Landlord reserves the right to stop any service or utility system when
necessary by reason of accident or emergency or until necessary repairs have been completed. Except in case of emergency repairs, Landlord will give Tenant reasonable advance notice of any contemplated stoppage and will use reasonable efforts to
avoid unnecessary inconvenience to Tenant by reason thereof such as conducting the same outside the regular business hours of Tenant. 

Except as set forth herein and in Article 7, the foregoing rights shall be Tenant’s sole remedy at law or in equity for the interruptions
described in this Section 5.2.

 ARTICLE 6 

TENANT’S COVENANTS 
  

	6.1	TENANT’S COVENANTS DURING THE TERM 

 Tenant covenants during the Term and such
further time as Tenant occupies any part of the Premises: 
 6.1.1 Tenant’s Payments - Except during Tenant’s early entry
pursuant to Section 3.2 above, to pay when due (a) all Fixed Rent and additional rent, (b); all taxes which may be imposed on Tenant’s personal property in the Premises (including, without limitation, Tenant’s furniture, fixtures
and equipment) regardless to whomever assessed, unless there is an uncured, continuing Event of Default of this Lease, at which time Landlord shall be responsible for the payment of any taxes associated therewith, (c) all charges by public
utility for telephone and other utility services (including service inspections therefore and the charges as may be imposed pursuant to Exhibit “D” hereof) rendered to the Premises not otherwise required hereunder to be furnished by
Landlord without charge and not consumed in connection with any services required to be furnished by Landlord without charge; 
 6.1.2
Repairs and Yielding Up - Except as otherwise provided in Article 7 and Section 5.1.3, to keep the Premises in substantially the same order, repair and condition as exists on the Commencement Date, reasonable wear and tear and damage by
fire, casually or act of God, the effect of eminent domain and Hazardous Materials not stored, used, released or disposed of by Tenant, its agents, employees, contractors or invitees only excepted, and at the expiration or termination of this Lease
peaceably to yield up the Premises and all changes and additions therein after initial construction and as designated by Landlord pursuant to its right to do so as Improvements to be removed on termination in such order, repair and condition, first
removing all goods and effects of Tenant and any items, the removal of which is required by Section 3.1 above or specified to be removed at Tenant’s election and which Tenant elects to remove, and repairing all damage caused by such
removal and restoring the Premises and leaving them clean and neat; any property not so removed shall be deemed abandoned and may, upon ten (10) business days’ prior written notice to Tenant, be removed and disposed of by Landlord, in such
manner as Landlord shall determine, and Tenant shall pay Landlord the entire cost and expense incurred by it by effecting such removal and disposition; it being agreed that the acceptance of reasonable use and wear shall not apply so as to permit
Tenant to keep 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 Occupancy and Use - To use the Premises only for the Permitted Uses; and not to injure or deface the Premises, Building or Lot or
Park; and not to permit in the Premises any auction sale, nuisance, or the emission from the Premises of any reasonably objectionable noise or odor; nor any use thereof which is contrary to law or ordinances, or invalidates or increases the premiums
for any insurance on the Building or its contents or liable to render necessary any 

  
 24 








 
alteration or addition to the Building unless Tenant agrees to pay the cost of the increased premiums or required alteration or addition (it being agreed that use for the Permitted Uses does not
violate the foregoing); 
 6.1.4 Rules and Regulations - To comply with the Rules and Regulations set forth in Exhibit “E”
and all other reasonable Rules and Regulations hereafter made by Landlord, of which Tenant has been given notice, for the use of the Building, Lot and Park and their facilities and approaches, it being understood that Landlord shall not be liable to
Tenant for the failure of other tenants of the Building or Park to conform to such Rules and Regulations, provided that Landlord enforces such rules against all tenants of the Building in a non-discriminatory fashion; 

6.1.5 Compliance with Laws and Safety Appliances - To keep the Premises equipped with all 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 of such use, it being understood that
the foregoing provisions shall not be construed to broaden in any way Tenant’s Permitted Uses. Tenant shall have the right, upon giving notice to the Landlord, to contest any obligation imposed upon it 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 this 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 (other than as part of Landlord’s Work); 

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 out of pocket 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 shall be reasonable and subject to the provisions hereinafter provided. 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 which 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 

  
 25 








 
Landlord, to be bound by all the obligations of Tenant thereafter arising 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 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, provided Landlord requests such information within ten (10) days of receipt of such notice from Tenant.
Landlord shall respond to a request for consent within ten (10) days of Tenant’s request for consent. 
 Notwithstanding any
provision contained in this Lease to the contrary, no consent of Landlord (or Landlord’s mortgagee) shall be required for A) the occupancy (including any assignment or subletting as hereinafter provided) of the Premises by any entity
controlling, controlled by or under common control with Tenant from time to time (an “Affiliate”), including, without limitation, Jones & Bartlett Learning, or B) the assignment of this Lease or the subletting of any portion (or
the whole) of the Premises, (i) to an Affiliate 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 assets are
transferred, (iii) to any corporation or other entity with which 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 Security posted pursuant to Article 11 hereof shall remain in place;
(y) such Permitted Transferee agrees directly with Landlord by written instrument to be bound by all of the obligations of Tenant thereafter arising hereunder, and (z) such Permitted Transferee under subsection (ii) shall have a net
worth of at least equal to or greater than that of Tenant immediately prior to such merger, reorganization or transfer of assets; and 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. 
 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 (other than an Affiliate) 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. 

  
 26 








 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 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 and against any
liability, claims, actions, proceedings and expenses and costs in connection therewith (including, without implied limitation, reasonable counsel fees) with respect to 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, (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, to the extent 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. Notwithstanding anything
to the contrary contained in this Lease, in no event shall Tenant be liable to Landlord for any indirect, consequential, special, exemplary, incidental or punitive damages arising from or relating to this Lease. In addition, Tenant shall pay
Landlord all reasonable costs and expenses incurred by Landlord in connection with the successful enforcement by Landlord of any obligations of 

  
 27 








 
Tenant under this Lease. 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; 

6.1.9 Tenant’s Workmen’s Compensation Insurance - To keep all Tenant’s employees working in the Premises covered by
workmen’s compensation insurance in statutory amounts; 
 6.1.10 Landlord’s Right of Entry - Upon not less than twenty four
(24) hours notice or other reasonable notice and during regular business hours (except in the event of an emergency), to permit Landlord and Landlord’s agents entry; to examine the Premises at reasonable times and, if Landlord shall so
elect and is otherwise permitted hereunder, to make repairs or replacements; to remove, at Tenant’s expense, any changes, additions, signs, curtains, blinds, shades, awnings, aerials, flagpoles, or the like not consented to in writing; and to
show the Premises to prospective tenants during the twelve (12) months preceding expiration of the Term and to prospective purchasers and mortgagees at all reasonable times. Notwithstanding anything to the contrary contained in this Lease, any
entry by Landlord and Landlord’s agents shall not 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; 
 6.1.11 Loading - Except with Landlord’s
prior written consent, not to place a load upon the Premises exceeding an average rate of one hundred (100) pounds of live load per square foot of floor area; and not to move any safe, vault or other heavy equipment in, about or out of the
Premises except in such a manner and at such times as Landlord reasonably shall in each instance approve; Tenant’s business machines and mechanical equipment which cause vibration or noise that may be transmitted to the Building structure or to
any other leased space in the Building shall be placed and maintained by Tenant in settings of cork, rubber, spring, or other types of vibration eliminators sufficient to eliminate such vibration or noise; 

6.1.12 Landlord’s Costs - In case Landlord shall, without any fault on its part, be made party to any litigation commenced by or
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
Landlord in connection with such litigation and as additional rent, also to pay all such costs and fees incurred by Landlord in connection with the successful enforcement by Landlord of any obligations of Tenant under this Lease;


  
 28 








 6.1.13 Tenant’s Property - All the furnishings, fixtures, equipment, effects and
property of every kind, nature and description of Tenant and of all persons claiming by, through or under Tenant which, during the continuance of this Lease or any occupancy of the Premises by Tenant or anyone claiming under Tenant, may be on the
Premises or elsewhere in the Building or on the Lot or elsewhere in the Park shall be at the sole risk and hazard of Tenant, and if the whole or any part thereof shall be destroyed or damaged by fire, water or otherwise, or by the leakage or
bursting of water pipes, steam pipes, or other pipes, by theft, or from any other cause, no part of said loss or damage is to be charged to or to be borne by Landlord except to the extent arising from Landlord willful act or negligence, or that of
its agents, employees or contractors, as required by law; 
 6.1.14 Labor or Materialmen’s Liens - To pay promptly when due the
entire cost of any work done on the Premises by Tenant, its agents, employees, or independent contractors; not to cause or permit any liens for labor or material performed or furnished in connection therewith to attach to the Premises; and
immediately to discharge any such liens which may so attach within twenty (20) business days after receipt of written notice of such attachment; 

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 such 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, so long as they do not materially adversely affect any of the mechanical, electrical or plumbing systems or life safety systems
of the Building or otherwise require Landlord unusual expense to readjust the Premises to normal office use on the Term Expiration Date (collectively herein called “Alterations”) whose cost in any one instance is Fifty Thousand Dollars
($50,000.00) or less, provided that Tenant first notifies Landlord in writing of any such Alterations and satisfies any reasonable requirements of Landlord’s with respect to insurance. If Tenant desires to make any Alterations costing in excess
of Fifty Thousand Dollars ($50,000.00) 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 or life safety systems, 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 (including 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. Tenant shall have no obligation to remove
an alteration at the end of the Term, unless Landlord notifies Tenant it will require removal of the same at the end of the Term at the time of its consent thereto. 

Any and all alterations, including but not limited to the Alterations (but excluding Alterations not requiring Landlord consent), shall be
performed by GCCI at cost plus a profit equal to six percent (6%) of the aggregate cost so long as the cost is comparable to the then 

  
 29 








 
market cost consistent with other similarly situated first-class buildings in the area of the Building, 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. Landlord agrees to employ an “open book” policy with respect to bidding all work requested by Tenant hereunder, including Tenant’s right to review all of such bids. 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 Landlord’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 (subject to the foregoing requirement that the cost be consistent with the then market cost and that Landlord provide Tenant with an
“open book” review of all bidding) 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. 
 At least annually if such Alterations or any other alterations
hereunder have occurred during the past calendar year (other than cosmetic alterations), 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(s) procure and maintain in effect during the term of such alterations, including Alterations, reasonably
satisfactory insurance coverages (including without limitation OCP coverage, if applicable) 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%) of 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 

  
 30 








 
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 thirty
(30) 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. 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 by Tenant, 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 (ii) if an independent, reputable third party engineer employed by Landlord or persons acting under Landlord conclusively determines that a release has occurred and 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 three (3) 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 

  
 31 








 
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 each party 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 tiling as may be permitted hereunder in good condition and repair at all times. 

Tenant shall have the right, at its sole cost and expense, subject to Landlord’s prior approval (not to be unreasonably withheld,
conditioned or delayed) and to applicable sign ordinances, and to receipt by Landlord of all required permits therefor, 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 the exterior of the Building at the location shown on Exhibit “B” (“Tenant’s Signage”), provided that Tenant and any Affiliate shall be leasing at all times at
least one (1) full floor of the Building, Landlord shall have the right to remove Tenant’s Signage, at Tenant’s expense for reasonable out-of-pocket expenses. Tenant’s right to install signage on the Building is non-exclusive.
Tenant’s name shall also be placed by Landlord on the Building directory, at no cost to Tenant, and Landlord agrees to work with Tenant to improve the signage in the main lobby of the Building. Tenant shall have the right to relocate
Tenant’s Signage to the exterior location of the Building where One Communications’ sign is currently located upon the termination of Landlord’s lease with such tenant (expressly excluding any assignments or subleasing to the
successors, assigns and affiliates of One Communications which shall have such rights that One Communications has as set forth in such lease), provided that (i) Tenant is then leasing and occupying two (2) full floors


  
 32 








 
in the Building or at least seventy-five thousand (75,000) rentable square feet and (ii) there does not then exist an Event of Default. 

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. 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. 

ARTICLE 7 
 CASUALTY AND TAKING

  

	7.1	CASUALTY AND TAKING 

 In case during the Term any substantial part of the Premises, or
all or any substantial part of the Building, or any one or more of them, are, in the reasonable judgment of Landlord’s architect, damaged materially by fire or any other cause, or by action of public or other authority in consequence thereof or
are taken by eminent domain, and this Lease is not otherwise terminated pursuant to Sections 7.3(c) or (d) below, then this Lease shall terminate at either party’s election, which may be made, notwithstanding Landlord’s entire
interest may have been divested, by notice given to the other party within thirty (30) days after the occurrence of the event giving rise to the election to terminate, which notice shall specify the 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. Such termination right may not be exercised by Landlord if the Premises are not damaged by such casualty or taking unless the leases of
all other tenant’s of the Building are also terminated. If in any such case the Lease is not so terminated, Landlord shall use due diligence to put the Premises and/or the Building, as applicable, or in case of taking, what may remain thereof
into substantially the condition immediately prior to the casualty, subject to applicable law, if the net award of insurance or damages are adequate (but such limitation shall not apply if the Landlord failed to maintain the insurance required
hereunder). A just proportion of the Fixed Rent and additional rent according to the nature and extent of the injury from and after the date of such casualty or taking shall be abated until the Premises, all systems and access thereto, 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 Landlord’s Operating Costs. 
  

	7.2	RESERVATION OF AWARD 

 Landlord reserves to itself any and all rights to receive awards
made for damages to the 

  
 33 








 
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, furniture, 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 

 (a) Landlord shall not be required to repair or replace
any of Tenant’s business machinery, equipment, furniture, personal property or other installations not originally installed by Landlord. 

(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 (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 within sixty (60) days after the casualty or notice of taking, 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 

  
 34 








 
needed to complete such restoration: (x) the Premises, with reasonable diligence, cannot be fully repaired by Landlord within twelve (12) months after the damage or destruction. 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. In addition, if Tenant does not terminate under this subsection
(d) within thirty (30) days of receipt of Landlord’s notice, and Landlord does not complete the repair within the time period stated in Landlord’s notice, Tenant shall again have the right to terminate this Lease by written
notice given within thirty (30) days of the expiration of the repair period stated in Landlord’s notice. 
 ARTICLE 8 

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 commercially reasonable and customary terms, substantially similar to the provisions contained in the
SNDA attached to this Lease. Further and as a condition to Tenant’s obligations under this Lease, Landlord agrees to obtain and deliver to Tenant within thirty (30) days of this Lease, a Subordination, Non-Disturbance and Attornment
Agreement (“SNDA”) from its current lender, Bank of America, N.A. (“Lender”), substantially in accordance with Exhibit “J” attached hereto. In the event an SNDA is not obtained from the Lender for the benefit of Tenant
within thirty (30) days from the date of this Lease, Tenant shall have the right to terminate this Lease. Landlord represents and warrants that (i) there is no default under the mortgage or related loan documents with the Lender, and
(ii) no other mortgage, ground lease or superior lease encumbers the Lot or the Building. 
  

	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


  
 35 








 
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 the holder as Landlord. 
  

	8.3	INTENTIONALLY OMITTED. 

  

	8.4	NO PREPAYMENT OR MODIFICATION, ETC. 

 No Fixed Rent, additional rent, or any other charge
shall be paid more than thirty (30) 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. 
  

	8.5	NO RELEASE OR TERMINATION 

 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. The foregoing shall not apply to any rights to Tenant to terminate in the event
of a casually or taking. 
  

	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 this 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 

  
 36 








 
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. 

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 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, provided that Tenant commences such cure within said thirty (30) day period; 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 time 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	TENANTS 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 present value total rent reserved for the residue of the Term discounted at a
rate equal to seven and one-half percent (7.5%) per annum. In calculating the rent reserved, there shall be 



  
 37 









	 	
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 re-letting 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 amounts 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 net proceeds of any rents obtained by Landlord by re-letting the Premises, after deducting all of Landlord’s reasonable expenses in connection with such re-letting, 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 re-letting the Premises or preparing the Premises for the
new tenant or tenants. 

 In no event shall Landlord receive total rent pursuant to Subparagraphs (a) and (b) above
(i.e. from Tenant and/or from any future tenant upon any reletting of the Premises, or a portion thereof) in excess of the actual damages due and payable by Tenant under said Subparagraphs. 

Landlord agrees to use commercially reasonable efforts to re-let the Premises following any such termination herein provided, however, that
Landlord: (x) may re-let 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 re-let same; (y) may make such alterations, repairs and decorations in the Premises as Landlord, in its reasonable
judgment, considers advisable or necessary to re-let the same, and no action of Landlord in accordance with the foregoing sub clauses (x) and/or (y), or Landlord’s failure to re-let or to collect the rent through re-letting,
shall operate or be construed to release or reduce Tenant’s liability as aforesaid; and (z) shall have no duty to re-let the Premises to a prospective tenant who is also interested in leasing other space that Landlord (or its
affiliate(s)) then has available. In the event that Landlord collects all of the rent reserved pursuant to Subparagraph (a) above, and re-lets the Premises following the termination of this Lease, then Landlord agrees to reimburse Tenant for
its pro rata share of any rent reserved paid by Tenant to Landlord hereunder in accordance with Subparagraph b(ii) above. 
 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


  
 38 








 
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. 
 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. 
  

	9.3	EVENTS OF DEFAULT BY LANDLORD. 

 It shall be an “Landlord Event of Default”
under this Lease, if Landlord fails to perform its obligations hereunder for more than thirty (30) days after notice thereof from Tenant, 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. In the event of a Landlord Event of Default, without limitation to any other rights Tenant may have at law and equity (each of which rights Tenant expressly reserves),
which default shall remain uncured after the expiration of any applicable notice and cure periods and Tenant does not have notice that Landlord is disputing such obligation in good faith, Tenant shall have the right, but shall not the obligation, to
perform such obligation. Notwithstanding any language to the contrary set forth in this Section, in no event shall Tenant have any right to perform any obligations that are outside of the Premises, that affect any space not leased by Tenant, that
affect any Common Area of the Building, the Lot or the Park, that affect the structure of the Building, or that affect any of the life safety or building systems of the Building. In performing such obligation, Tenant may make any payment of money or
perform any other act. All sums so paid by Tenant, together with interest at the rate of twelve percent (12%) per annum, and all necessary incidental costs and expenses, provided such are reasonable, in connection with the performance of any
such acts by Tenant, shall be payable by Landlord to Tenant within twenty (20) days of demand (containing all reasonable documentation evidencing such performance and payment by Tenant). Tenant may exercise the foregoing rights without waiving
any other of its rights or releasing Landlord from any of its obligations under this Lease.

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

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.

unenforceable shall remain in effect as far as possible in accordance with the intention of the parties.

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 reasonable 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

thereafter, upon not less than twenty (20) 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” with such adjustments

statement in writing in substantially the form attached hereto as Exhibit “K”. 
  

	10.13	WAIVER OF SUBROGATION AND CLAIMS 

 Any insurance carried by either party with respect to
the Premises and property therein or occurrences thereon shall 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 (or would have been covered had all insurance required hereunder been maintained). 
  

	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 Grubb & Ellis Company (collectively, the “Broker”). Each party agrees to hold the other party harmless from and against all claims for

fee to the Broker pursuant to a separate agreement. 

  
 42 









	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

 ARTICLE 11 

SECURITY 
 A security
deposit in the amount of Seven Hundred Fifty Thousand Dollars ($750,000.00) shall he delivered by Tenant to Landlord on or prior to the Commencement Date (the “Security”). Such Security shall be in the form of a Letter of Credit in
substantially the form attached hereto as Exhibit “M”, and 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 (e) be drawn on an
FDIC-insured financial institution reasonably satisfactory to Landlord. Landlord agrees that GE Capital is an acceptable institution. 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 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 there does not then exist an Event of Default, the amount of the required Security shall be reduced In accordance with the following schedule;
(i) by $250,000.00 on the 1st day of month twenty five (25) of the Term; and (ii) by an additional $200,000.00 on the lst day of
month thirty seven (37) of the Term. Thereafter, the Security shall be Three Hundred Thousand Dollars and 00/100 ($300,000.00). Landlord agrees to promptly return any existing Letter of Credit to Tenant upon Landlord’s receipt of a
replacement Letter of Credit in such reduced amount required hereunder. In the event that Landlord fails to release any cash proceeds drawn from a Letter of Credit (if applicable) within five (5) business days following the required date (or
its receipt of a replacement Letter of Credit conforming to the requirements hereunder), then Landlord shall be obligated to pay Tenant interest on any such amount at the interest rate set forth in Section 4.3 hereof, calculated on a daily
basis. 

  
 44 








 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 Letter of Credit to the then applicable full amount (or post a cash Security, at Tenant’s option). 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. At the later of the termination of this Lease and the date Tenant surrenders the Premises to Landlord in accordance with this Lease, the balance of the Security, either
cash or the Letter of Credit, as applicable, shall be returned to Tenant within thirty (30) 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 provided such transferee acknowledges receipt
of the same in writing. 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, 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.

not be more than a five percent (5%) decrease in the net effective rent thereunder ; otherwise, Landlord shall re-offer the space to Tenant, in accordance with the terms of this Exhibit “I”). The non-exercise by Tenant of its rights
under this Exhibit “I” as to any particular ROFO Space described in a particular Offer by Landlord shall not be deemed to waive any of Tenant’s rights of first offer as to the remainder of ROFO Space that becomes available.
This right of first offer shall be considered a reviving offer as to space that becomes available on floor four (4) of the Building only, but any failure to lease ROFO Space shall be deemed to waive any of Tenant’s rights of first offer as
to the remainder of the ROFO Space (I.e. Tenant’s rights hereunder shall not revive), as this right shall be considered a one-time non-reviving right as to ROFO Space on floors 2, 5 and 6 in the Building. Notwithstanding the foregoing, except
as otherwise provided in Exhibit “N”, Landlord and Tenant hereby acknowledge and agree that no additional notice shall be required from Landlord regarding the existing space located on the fourth (4th) floor until such space has been leased to a third party and once again becomes available. 

In the event that Tenant accepts Landlord’s offer to lease such ROFO Space described in the Offer, 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 port 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 

  
 71 








 
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 the foregoing, Tenant’s rights hereunder shall be subject and subordinate to the existing Right of
First Refusal of Conversent Communications of Massachusetts, Inc., d/b/a One Communications to lease space that becomes available on the fourth (4th) floor of the Building.

to New Owner.
