 THIS SUBLEASE WITNESSETH THAT:

 WHEREAS: the Owner, as Lessor, and the Landlord, as Lessee, executed that certain lease agreement dated January 1, 1999
(the “Lease”), a copy of which is attached hereto as Exhibit B, for the lease of 25 Hartwell, and 
 WHEREAS: Tenant desires to lease the Premises
from Landlord and the Landlord desires to lease the Premises to Tenant; 
 NOW, THEREFORE, in consideration of the above, and the representations,
warranties, covenants and conditions contained in this Sublease, Landlord and Tenant, intending to be legally bound, agree as follows: 
 1. Owner’s
Consent. Landlord and Tenant’s obligations under this Sublease, and the effectiveness of this Sublease, are conditioned upon Owner providing written consent to this Sublease in form reasonably acceptable to Tenant, which consent shall
include Tenant’s right to transfer its interest in the Sublease without consent as provided in Section 13 hereof. Landlord shall pay any fees or expenses charged by Owner in connection with such consent. If such consent is not obtained
within fifteen (15) days after the execution hereof, then Tenant may terminate this Sublease by written notice to Landlord, whereupon any security deposit, letter of credit, or other prepaid amounts shall be promptly refunded and returned by
Landlord to Tenant. 







 2. Demise. By this Sublease, Landlord leases to Tenant, and Tenant does hereby lease and take from
Landlord, subject to and upon the terms, covenants, agreements, provisions and conditions hereinafter set forth, the Premises. 
 3. Rights Granted.
The Sublease of the Premises to Tenant includes all rights, privileges, easements and other interests appurtenant to the Premises, including but not limited to any access, utility and other rights and easements benefiting the Premises. 

4. Term. The term of this Sublease shall commence as of 12:01:01 AM on the date of Owner’s consent to this Sublease (the “Commencement
Date”) and shall expire at 12:59:59 PM on December 31 2016 (the “Term”), unless earlier terminated pursuant to the terms of this Sublease. The Tenant shall not have legal occupancy of the Premises until a Certificate of Occupancy
is issued by Lexington, provided, however, that the Tenant’s contractors may be present in the Premises on and after the Effective Date for the purpose of performing the Tenant Improvements permitted under the Sublease, once they have
demonstrated that they have the required insurance coverages, and provided that the Tenant will be responsible for the cost of all utilities, water and sewer charges incurred in the Premises by the Tenant or its contractors after the Effective Date.

 5. Base Rent. The Tenant covenants and agrees to pay Base Rent to the Landlord as set forth in the following table for the full Term of this
Sublease (“Rent”). No Base Rent as set forth the following table shall be payable from the date hereof through April 30, 2014; provided, however, that the Tenant recognizes and agrees that it will pay taxes, fees, and operating
expenses as set forth the balance of this Paragraph 5.

	 	Total Rent for the Period	 	 	Rent/Square Foot	 	 	Monthly Rent	 
					
	1	 	 1 May 2014 to 30 April 2015
	 	$	583,432.50	  	 	at $	17.50 PSF	  	 	$	48,619.38	  
					
		 	 1 May 2015 to 30 April 2016

		 	 1 May 2016 to 31 December 2016
	 	$	411,181.00	  	 	$	18.50 PSF	  	 	 	51,397.62	  

 Base Rent during any partial calendar month during the Term shall be prorated based on the number of days in such month which
are included in the Term. 
 During the Term of the Sublease, or beginning on such earlier date that the Tenant or its agents begin renovation work in the
Premises, and except as otherwise specifically set forth in Paragraph 7 below, in addition to the Base Rent set forth above, the Tenant will be as responsible as if it were the Lessee, for the costs of all utilities used in the Premises and for
cleaning, trash removal, repairing, and maintaining the Premises. From August 1, 2013 through April 30, 2014, or when the Tenant takes occupancy of the Premises for operation of Tenant’s business if earlier than August 1, 2013,
the Tenant will also pay (A) the Capital Reserve Fee (currently $972.39 per month) payable by Lessor under the Lease, and (B) 50% of (i) the escalated real estate taxes, and 







 
(ii) other escalated operating expenses that the Lessee has agreed with the Lessor to pay to Lessor under the Lease (i.e., operating expenses to the extent they exceed the operating expenses for
the 2006 calendar year and taxes to the extent they exceed the taxes for the 2006 tax fiscal year). The real estate taxes payable by Lessor under the Lease are estimated to be $2,118.25 (as stipulated in the January 15, 2013 reconciliation
letter (identified below as Exhibit C) as “Real Estate Tax payments”) per month (based on the current estimated charge from Owner) and the operating expenses payable by Lessor under the Lease are estimated to be: $901.65 as stipulated in
the April 16, 2013 reconciliation letter (identified below as Exhibit C) “Est. operating payments”) per month (based on the current estimated charge from Owner). Notwithstanding the amounts of any estimates, the Tenant will pay the
actual amounts, as adjusted by the reconciliations provided for in the last two sentences of this Paragraph 5. Tenant shall pay 50% of such estimated operating expense and tax amounts monthly. Further, from August 1, 2013 through April 30,
2014, or when the Tenant takes occupancy of the Premises for operation of Tenant’s business if earlier than August 1, 2013, the Tenant will pay an amount equal to the entire real estate taxes and operating expenses (each as defined in the
Lease) for the Premises without reference to a base year, in estimated monthly installments, for the corresponding August 1, 2013 through April 30, 2014 period. The 2013 operating expenses are currently estimated by Owner to be $52,826.91
per annum ($4,402.24 per month) and the taxes are currently estimated by Owner to be $103,213.45 ($8,601.12 per month). The Landlord has obtained from the Owner provided to the Tenant the Owner’s current detailed breakdown of those taxes and
expenses and how they have been calculated, and that breakdown is set forth in Exhibit C annexed hereto and made a part hereof. Upon receiving a reconciliation statement from Owner with respect to operating expenses or taxes payable pursuant to this
Section 5 or Sections 8 and 9, Landlord shall provide the same to Tenant, and within ten (10) days thereafter, Tenant shall pay to Landlord any underpayment of operating expenses and taxes or Landlord shall refund to Tenant any overpayment
of the same, as the case may be. 
 6. Access, Tenant Improvements. The Tenant will be allowed access to the Premises immediately following the
Effective Date for purposes of construction of Tenant’s build-out, set-up and equipment installation. In making its Tenant Improvements, the Tenant will comply in all respects with Paragraph 12 of the Lease and deal directly with the Lessor as
if it were the Lessee under the Lease, mutatis mutandis. The Tenant will comply with all permitting and inspectional requirements of Federal, Massachusetts and Lexington laws, ordinances and Regulations in making its Tenant Improvements. If Landlord
consents to Tenant’s making Tenant Improvements in accordance with Paragraph 12 of the Lease, Landlord shall use commercially reasonable efforts to request and obtain any consent from Owner required in connection with the performance of Tenant
Improvements. 
 7. Utilities, Insurance. During the entire Term of the Sublease, in addition to the Base Rental Rate set forth above the Tenant will
be as responsible as if it were the Lessee under the Lease, for the additional costs of electricity, water and sewer charges, and all other utilities used in the Premises and for cleaning, trash removal, repairing, and maintaining the Premises. The
Tenant will obtain and maintain, and require its contractors performing Tenant Improvements to obtain and maintain, the types and levels of insurance required of the Lessee under Paragraphs 10 and 17 of the Lease from the first day of access through
the entire Term of the Sublease, naming the Landlord and the Owner as additional insureds as their interests may appear. 







 8. Rent Adjustment for Taxes. Paragraph 6 A. of the Lease provides that the Lessee will pay the Lessor for
any increase in real estate taxes imposed by Lexington over a certain base year. For the purposes of this Sublease, commencing on May 1, 2014, the Tenant shall pay to the Landlord the amount of any increase in the real estate taxes and water
and sewer charges applicable to the Premises over the amount paid in the Town’s 2014 Fiscal Year (ending 30 June 2014). In all respects other than the base year, the provisions of Paragraph 6 of the Lease shall apply to this Sublease as if
the Lessor and the Lessee in the Lease were the Landlord and the Tenant, respectively, in this Sublease, mutatis mutandis. Tenant’s obligations in respect of real estate taxes and water and sewer charges for the period before May 1, 2014
are as provided in the last paragraph of Section 5 hereof. 
 9. Rent Adjustment for Operating Expenses. Paragraph 6 B. of the Lease provides
that the Lessee will pay the Lessor for any increase in operating expenses over a certain base year. For the purposes of this Sublease, commencing on May 1, 2014, the Tenant shall pay to the Landlord the amount of any increase in operating
expenses applicable to the Premises over the amount paid by the Landlord as Lessee in Calendar Year 2013. In all respects other than the base year, the provisions of Paragraph 6 B. of the Lease shall apply to this Sublease as if the Lessor and the
Lessee in the Lease were the Landlord and the Tenant, respectively, in this Sublease, mutatis mutandis. Tenant shall also pay the Capital Reserve Fee described in Section 4 of the Lease. Tenant’s obligations in respect of operating
expenses and Capital Reserve Fees for the period before May 1, 2014 are as provided in the last paragraph of Section 5 hereof. 
 10. Use.
Notwithstanding Paragraph 7 of the Lease, the Tenant may use the Premises for all purposes permitted under the Lease including light manufacturing, assembly, and research and development related to Tenant’s non-surgical, non-pharmaceutical
therapy for the treatment of type-2 diabetes and/or obesity. Tenant shall have 24/7 access to the Premises and use of all parking spaces appurtenant to the Premises under the Lease. 

11. No Option to Extend. Notwithstanding anything contained in Paragraph 25 of the Lease, the Tenant has no option to extend the Term of this Sublease.
The Landlord has no objection to the Tenant’s making a separate arrangement with the Owner provided that any such arrangement imposes no obligation whatsoever on the Landlord. Landlord agrees that if Tenant enters into an agreement with Owner
giving Tenant the option to enter into a direct lease with Owner, then Landlord shall not extend the term of the Lease or exercise any extension option allowing for the extension of the Lease term. However, such direct lease option agreement shall
provide that Tenant must exercise its option to lease the Premises from Owner by notice given to Owner by no later than February 29, 2016, to allow Landlord time to exercise its option to renew under the Lease if Tenant does not exercise the
direct lease option. Landlord agrees that if Tenant timely exercises its direct lease option, then Landlord’s extension rights under the Lease shall automatically be of no force and effect, and Landlord agrees that Owner may rely on this
statement in entering into a direct lease with Tenant. Upon written request from time to time, Tenant agrees to promptly inform Landlord whether the Tenant’s direct lease option is still in full force or effect, has expired, or the Tenant has
decided to waive its right to enter a direct lease with the Owner. 
 12. Condition of the Premises. Upon the expiration of the Term, the Landlord
will not be responsible for removing from the Premises any tenant improvements or alterations constructed 







 
by Tenant, nor for removing any of Tenant’s personal property, fixtures, or equipment, including the property to be conveyed to Tenant pursuant to this paragraph, and the Tenant will
indemnify and hold the Landlord harmless from any claim made by the Owner against the Landlord for not removing such tenant improvements, alterations, or property. Upon the expiration or termination of the Lease, unless Tenant and Owner enter into a
direct lease agreement, Tenant shall remove all of its personal property, fixtures, and equipment from the Premises, and, if required by Landlord, shall remove all tenant improvements and alterations installed by Tenant. The Parties agree that the
Owner’s instrument of consent to this Sublease will contain a provision stating that the Owner as Lessor agrees that if the Tenant fails to restore the Premises upon surrender to the condition existing prior to Tenant making its Tenant
Improvements, the Owner will not look to the Landlord for the cost of such restoration, provided, however, that if such instrument of consent does not contain such agreement from the Owner, then the Tenant will indemnify and hold the Landlord
harmless from any claim made by the Owner against the Landlord for not restoring the Premises as required. Owner and Landlord agree that upon the expiration or termination of the Term, Tenant shall not be required to remove any tenant improvements
or alterations that were existing in the Premises as of the Commencement Date, nor to repair any reasonable wear and tear or damage caused by casualty or condemnation. By this Lease, Landlord hereby conveys to Tenant for $1.00 all of Landlord’s
furniture, fixtures, and equipment in the Premises, which Landlord shall leave in the Premises. Tenant agrees to accept such furniture, fixtures, and equipment “AS IS”, “Where Is,” and with no warranties or representations of any
kind, except that Landlord shall convey such property free of any liens or claims by third parties, and the Tenant will pay the cost of disposing of any of the furniture, fixtures, and equipment that it elects not to keep or sell. 

13. Assignment and Transfer of Sublease. The Tenant shall not assign or further sublet the whole or any part of the Premises without the prior written
consent of both the Owner and the Landlord, which consent will be subject to the standards set forth in Paragraph 13 of the Lease. Notwithstanding the foregoing, the Landlord may, upon written notice to the Tenant, assign or transfer its interest in
this Sublease (a) to any person or entity succeeding to all or substantially all of the assets of the Landlord, or (b) to a successor entity in a merger or acquisition transaction. Where Owner’s consent is required under the Lease to
a proposed sublease, transfer, or assignment by Tenant, Landlord shall use commercially reasonable efforts to request and obtain such consent from Landlord. So long as such transfers are for a bona fide business purpose and not to evade
Tenant’s obligations under the Sublease, Owner and Landlord’s consent shall not be required in connection with the assignment of the Tenant’s rights under this Sublease to (i) an entity buying all or substantially all of
Tenant’s assets, or (ii) an entity with which or into which Tenant is merged, or (iii) to an entity controlling, controlled by, or under common control with Tenant; provided, however, that in each such case the assignee or sublessee
of the Tenant demonstrate financial ability at least equal to the level demonstrated to the Owner at the time of the Owner’s consent to this Sublease and, in the case of sections (ii) and (iii) of this sentence, the Tenant shall
retain full responsibility for the performance of the Tenant under this Sublease. 
 14. Liens. The Tenant shall not directly or indirectly cause,
create, incur, assume or suffer to exist any mortgage, pledge, lien (including mechanics’, labor or materialman’s lien), charge, security interest, encumbrance or claim on or with respect to the Premises. If the Tenant breaches its
obligations under this Paragraph 14, it shall immediately notify Landlord in writing, 







 
shall promptly cause such liens to be discharged and released of record without cost to Landlord and shall indemnify Landlord against all costs and expenses (including reasonable attorneys’
fees and court costs at trial and on appeal) incurred in discharging and releasing such liens. 
 15. Indemnification. Tenant and Landlord (each, in
such case, an “Indemnifying Party”) shall indemnify, defend and hold the other Party and its employees, directors, officers, managers, members, shareholders and agents (each, in such case, an “Indemnified Party”) harmless from
and against any and all third party claims, suits, damages, losses, liabilities, expenses and costs (including reasonable attorney’s fees) including without limitation those arising out of property damage (including environmental claims) and
personal injury and bodily injury (including death, sickness and disease) to the extent caused by the Indemnifying Party’s (a) material breach of any obligation, representation or warranty contained herein and/or (b) negligence or
willful misconduct; provided, however, that the Indemnifying Party will not have any obligation to indemnify the Indemnified Party from or against any indemnity claims to the extent caused by, resulting from, relating to or arising out of the
negligence or willful misconduct of the Indemnified Party. The Indemnifying Party shall have the right to select counsel and to direct the defense or settlement of any such proceeding 

16. Clauses of the Lease Incorporated by Reference; Lease Representations and Covenants. 

16.1 Paragraphs 14 (Subordination), 15 (Lessor’s Access), 16 (Indemnification and Liability), 18 (Fire, Casualty, Eminent Domain), 21
(Surrender), 30 (Estoppel Certificate), and 31 (Hazardous Substances), are incorporated into this Sublease with the full force and effect as if they were stated in full text herein, except that where the term “the Lessor” appears it shall
be deemed to mean the Owner and the Landlord, jointly and severally, and where the term “the Lessee” appears it shall be deemed to mean the Tenant. 

16.2 Paragraphs 19 (Default and Subordination) and 22 (Late Fees) are incorporated into this Sublease with the full force and effect as if
they were stated in full text herein, except that where the term “the Lessor” appears it shall be deemed to be the Landlord and where the term “the Lessee” appears it shall be deemed to mean the Tenant. 

16.3 If there is any conflict between the terms of the Lease and this Sublease, then as between Landlord and Tenant, this Sublease shall
control. 
 16.4 Landlord represents and warrants to Tenant that the Lease is in full force and effect and has not been altered or amended
except as set forth in Exhibit A. Landlord represents and warrants to Tenant that to Landlord’s knowledge as of the date hereof, there are no defaults by Landlord or Owner existing beyond any applicable notice and cure periods under the Lease,
or any events or circumstances which, by the giving or notice or the passage of time, would constitute a default under the Lease by Landlord or Owner. Landlord has not previously assigned, transferred or subleased its interest in the Premises or the
Lease. 
 16.5 Landlord will pay and perform all obligations under the Lease including without limitation all monetary obligations under the
Lease, subject to payment or reimbursement from Tenant to Landlord for those sums to be paid by Tenant hereunder, and other than those other obligations to be performed by Tenant hereunder. Landlord will not voluntarily do, or fail to do,








 
anything which will constitute a default which is continuing beyond any applicable notice and cure periods under the Lease or permit the Lease to be terminated for any reason. Landlord shall not
amend the Lease in any manner that would adversely affect Tenant’s rights or obligations hereunder or terminate the Lease. 
 16.6
Tenant acknowledges that the maintenance and services to be provided under the terms of the Lease by Lessor will be provided by Owner. Landlord will use commercially reasonable efforts to cause Owner to comply with all obligations of Owner under the
Lease with respect to the delivery of services and maintenance to be performed by Owner under the Lease. If Landlord is entitled under the Lease to any abatement of rents thereunder based on Owner’s failure to provide maintenance, repair, or
services, then Tenant shall receive a corresponding abatement hereunder.

 A notice given by United States mail will be deemed given at the close of business on the third (3rd) business day next subsequent to the date of mailing indicated on the official Postal Service receipt, or upon actual receipt or upon refusal to accept delivery, whichever shall first occur.
Notice given by courier or by personal service shall be deemed given upon receipt, as demonstrated by a written or electronic receipt. “Refusal to accept delivery” shall be deemed to occur when the notice is presented for delivery
by the postal carrier or courier and a representative of the Party to be served declines to sign to accept service and the notice for that reason cannot be delivered. A Party may change its address for notices by giving notice to the other Party of
the change in the manner aforesaid. 







 18. Brokerage. A brokerage fee shall be paid to NAI Hunneman and Richards Barry Joyce & Partners
(the “Brokers”) by the Landlord pursuant to a separate agreement. The Landlord and the Tenant warrant and represent, each to the other respectively, that neither of them, respectively, has dealt with any broker, finder or other person
entitled to a brokerage commission in connection with the negotiation or execution of this Agreement, or the consummation of the transactions contemplated herein other than the Brokers. The Landlord and the Tenant agree to indemnify, defend and hold
each other, respectively, harmless from and against all damages, claims, losses, and liabilities (including, without limitation, legal fees incurred in defending against such damages, claims, losses and liabilities) arising out of or resulting from
the failure of such representation or warranty. 
 19. Signage. The Tenant, at the Tenant’s cost, will have the right to signage on the monument
at the entrance to the Building, subject to Lexington code and to the Landlord and Owner’s approval pursuant to the standards set forth in Paragraph 26 of the Lease. Landlord shall use reasonable efforts to obtain Owner’s approval under
the Lease. 
 20. Force Majeure. In the event that either Party is delayed in or prevented from performing or carrying out its obligations under this
Sublease, other than the payment of monetary obligations when due, by reason of any cause beyond the reasonable control of, and without the fault or negligence of, such Party (and excluding lack of funds) (an event of “Force Majeure”),
such circumstance shall not constitute an Event of Default, and such Party shall be excused from performance hereunder and shall not be liable to the other Party for or on account of any loss, damage, injury or expense resulting from, or arising out
of, such delay or prevention; provided, however, that the Party encountering such delay or prevention shall use commercially reasonable efforts to remove the causes thereof (with failure to use such efforts constituting an Event of Default
hereunder). The settlement of strikes and labor disturbances shall be wholly within the control of the Party experiencing that difficulty. 
 21.
Security Deposit. Upon the Effective Date the Tenant will pay to the Landlord the amount of $149,504.58 in the form of cash or a Letter of Credit, which will be held as a security deposit to secure the Tenant’s performance of its
obligations under this Sublease. If Tenant initially posts the security deposit in cash, it may at its option subsequently replace such cash deposit with an automatically-renewable Letter of Credit, and upon
doing so, Landlord shall refund to Tenant any cash deposit then held by Landlord. Landlord may apply such cash deposit or Letter of Credit from time to time to Tenant’s obligations under this Sublease should Tenant default beyond applicable
notice and cure periods in the timely payment and performance of the same. If the Landlord is required to use any of the security deposit to cover the Tenant’s failure to perform an obligation, then, upon written notice with a summary
explanation of the reasons that the Landlord has been required to draw down the security deposit, the Tenant will pay additional money to the Landlord to bring the security deposit up to the original level. Upon the expiration of this Sublease, the
Landlord will refund any unused balance of any cash security deposit to the Tenant, or the original Letter of credit, as applicable, less any amounts applied by Landlord to pay or cure any default by Tenant in performance of Tenant’s
obligations hereunder. 







 22. General Provisions. 

22.1 Quiet Possession. Landlord agrees that the Tenant, subject to Tenant’s compliance with all material provisions contained in
this Sublease, will have quiet and peaceful possession of the Premises throughout the Term. Landlord represents and warrants that there are no restrictions, encumbrances or liens on the Premises that would prohibit, limit or restrict the activities
contemplated by this Sublease. 
 22.2 Authority of the Landlord. Landlord hereby represents and warrants that: (a) Landlord is
duly organized, validly existing and in good standing under the laws of Massachusetts and has all requisite power and authority to enter into this Sublease, to perform its obligations hereunder and to consummate the transactions contemplated hereby;
(b) the execution and delivery of this Sublease and the performance of Landlord’s obligations hereunder have been duly authorized by all necessary company action; and (c) this Sublease is a legal, valid and binding obligation of

(ii) the application of general principles of equity (regardless of whether considered in a proceeding in equity or at law). 
 22.4
Construction. Where the context so requires or permits, the use of the singular form includes the plural, and the use of the plural form includes the singular, and the use of any gender includes any and all genders. The use in this Sublease
of the term “including” means “including without limitation” The words “herein,” “hereof,” “hereunder” and other words of similar import refer to this Sublease as a whole, including the schedules and
exhibits, as the same may from time to time be amended, modified, supplemented or restated, and not to any particular section, subsection, paragraph, subparagraph or clause contained in this Sublease. The title of and the section and paragraph
headings in this Sublease are for convenience of reference only and shall not govern or affect the interpretation of any of the terms or provisions of this Sublease. Where specific language is used to clarify by example a general statement contained
herein, such specific language shall not be deemed to modify, limit or restrict in any manner the construction of the general statement to which it relates. The Parties have participated jointly in the negotiation and drafting of this Sublease. In
the event an ambiguity or question of intent or interpretation arises, this Sublease shall be construed as if drafted jointly by the Parties and no presumption or burden of proof shall arise favoring or disfavoring any Party by virtue of the








 
authorship of any of the provisions of this Sublease. Any reference to any federal, state, local or foreign statute or law shall be deemed also to refer to all rules and regulations promulgated
thereunder, unless the context requires otherwise. 
 22.5 Integration, Modification, Counterparts, Time. This Agreement constitutes
the entire agreement by and between the Parties with respect to the subject matter herein and supersedes all prior agreements between the Parties, whether written or oral, relating to the same subject matter. Without limiting or modifying the
restrictions set forth in this Sublease, the covenants and agreements contained in this Sublease shall be binding upon and shall inure to the benefit of the Parties to this Sublease and their respective permitted successors and assigns. No
modification, amendments, or supplements to this Agreement shall be effective for any purpose unless in writing and signed by each Party. Approval or consent of a Party concerning this Agreement shall also be in writing. This Agreement shall be
governed by and interpreted in accordance with the law of the Commonwealth of Massachusetts, USA, whose courts shall have jurisdiction of and in which venue shall lie for any dispute which may be brought in connection with the breach or
interpretation of this Agreement. Nothing in this Agreement, express or implied, is intended or shall be construed to confer upon or give any third party, whether a natural or a juridical person, any right, covenant or agreement herein set forth;
and all rights, covenants, and agreements herein contained shall be for the sole and exclusive benefit of the Parties hereto and their respective permitted successors and assigns. This Agreement may be executed in multiple original counterparts, all
of which shall be taken together as one and the same agreement. Any copy of this Sublease executed with original signatures (whether in ink or electronic form) is deemed to be an original of this Sublease for all purposes. Time is of the essence for
the performance and observation of each covenant of this Sublease. 
 22.6 Severability, Waiver. If any one or more of the provisions
contained in this Sublease shall for any reason be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision of this Sublease, but this Sublease shall be
construed as if such invalid, illegal or unenforceable provision had not been contained in this Sublease. Either Party may enforce all provisions of this Sublease strictly, regardless of (a) any law, usage, or custom to the contrary,
(b) any conduct of the enforcing Party in refraining from enforcing any provisions of this Sublease at any time, (c) any conduct of the enforcing Party in refraining from exercising its rights and remedies under this Sublease, and
(d) any course of conduct between Landlord and Tenant. Any conduct or custom between Landlord and Tenant must not be construed as having created a custom in any way or manner contrary to any specific provision of this Sublease, or as having in
any way or manner modified the same. 
 22.7 No Partnership. Landlord and Tenant agree that nothing contained in this Sublease shall
be deemed or construed as creating a partnership, joint venture, or association between Landlord and Tenant, nor cause either of them to be responsible in any way for the debts or obligations of the other Party. 

22.8 Cooperation. Upon the receipt of a written request from the other Party, each Party will execute such additional documents,
instruments and assurances and take such additional actions as are reasonably necessary and desirable to carry out the terms and intent of this Sublease. The Parties acknowledge that they are entering into a long-term arrangement in which their

	5.	SECURITY DEPOSIT: 

 Upon the execution of this lease, the LESSEE shall either:

 (a) Pay to the LESSOR the amount of $139,607.06 dollars which shall be held as a security for the LESSEE’S performance as herein
provided and refunded to the LESSEE at the end of this lease subject to the LESSEE’S satisfactory compliance with the conditions hereof. The LESSEE shall maintain at all times a security deposit equivalent to a minimum of three
(3) month’s base rent. This would include any and all options to renew; or 
 (b) Simultaneously with the execution and delivery of
this Lease, LESSEE shall deliver to LESSOR a standby, irrevocable, unconditional, transferable, automatically renewable letter of credit in the amount of $139,607.06 dollars, in substantially the form attached hereto as Exhibit Cs and issued by a
Massachusetts bank reasonably acceptable to LESSOR and containing the terms as required herein. LESSOR hereby approves Citizens Bank of Massachusetts as an acceptable issuer of the letter of credit as of the date of this Lease. During the term
hereof, and any extensions thereof, or for so long thereafter as LESSEE is in possession of the Premises or has unsatisfied obligations 







 
hereunder to LESSOR, but in no event less than thirty (30) days after the expiration of the lease term as extended, the letter of credit shall be held to ensure the full and timely
performance of LESSEE’S obligations under this Lease and for all losses and damages LESSOR may suffer as a result of any default beyond all applicable notice and cure periods, by LESSEE under this Lease; which letter of credit may be drawn upon
by LESSOR and applied from time to time against outstanding obligations of LESSEE hereunder without notice or demand provided LESSEE is in default of its obligations under the Lease beyond all applicable notice and cure periods. LESSEE shall have no
right to require LESSOR to so draw and apply the letter of credit, nor shall LESSEE be entitled to credit the same against rents or other sums payable hereunder. During the entire term hereof, including any extension thereof, LESSEE shall cause said
letter of credit to be renewed, in identical form to that delivered herewith, no later than 30 days prior to the date of expiration of same. It shall be a condition of the letter of credit that the letter of credit shall be deemed automatically
extended unless the issuing bank shall notify the LESSOR by certified mail return receipt requested, at least thirty (30) days prior to the then current expiration date of the letter of credit, that the letter of credit will not be extended
beyond the then current expiration date. The letter of credit shall state that, without limiting any other remedies of LESSOR, in the event that the LESSOR receives notice of termination or expiration of the letter of credit or if LESSEE fails to
renew any letter of credit given hereunder at least 30 days prior to the date of expiration thereof, then LESSOR shall have the right to draw down the entire amount of said letter of credit and hold such sums as a cash deposit. If and to the extent
that LESSOR makes such use of the letter of credit, or any part thereof, the sum so applied by LESSOR (from cash or from a drawing on the letter of credit) shall be restored to the letter of credit (or by anew letter of credit equal to the
difference) by LESSEE upon notice from LESSOR. 
 The LESSEE shall cause the letter of credit to be continuously maintained in effect
(whether through replacement, renewal, or extension) in an amount equivalent to a minimum of three (3) month’s base rent. This would include any and all options to renew. 

In the event LESSEE is unable to obtain the letter of credit on or before the date the LESSEE executes this Lease, LESSEE may, concurrently
with LESSEE’S execution of this Lease, provide a cash security in accordance with Article 5(a) above, and thereafter obtain a letter of credit which conforms to the terms of this Article 5(b). Provided the LESSEE obtains said letter of credit
within ninety (90) days from the date the LESSEE executes this Lease, the LESSOR shall, so long as the LESSEE is not in default beyond any applicable cure period, refund the cash security in exchange for an acceptable letter of credit which
complies with the above-mentioned terms.

	18.	FIRE, CASUALTY - EMINENT DOMAIN: 

 Should a substantial portion (50% or more) of
the Leased Premises, or of the property of which they are a part be substantially damaged by fire or other casualty, or be taken by eminent domain, the either party may elect to terminate this lease, When, through no -fault of the LESSEE, such fire,
casualty, or taking renders the Leased Premises substantially unsuitable, in whole or part, for their intended use, a just and proportionate abatement of rent shalt be made, and the LESSEE may elect to terminate this lease if; 

 

	 	(a)	The LESSOR fails to give written notice within thirty (30) days of intention to restore Leased Premises, or 

  

	 	(b)	The LESSOR fails to restore the Leased Premises to a condition substantially suitable for their intended use within ninety (90) days of said fire, casualty or taking. 


If neither party terminates pursuant to this Article 18, LESSOR shall restore the Leased Premises to the condition they were in prior to the
casualty. 
 The LESSOR reserves and the LESSEE grants to the LESSOR, all rights which the LESSEE may have for damages or injury to the
Leased Premises for any taking by eminent domain, except for damage to the LESSEE’S fixtures, property or equipment. 
  

	19.	DEFAULT AND BANKRUPTCY: 

 (A) In the event that: 

 

	 	(a)	The LESSEE shall default in the payment of any installment of rent, additional rent, or other sum herein specified and such default shall continue for five (5) business days following written notice; provided that
the LESSEE shall only be entitled to two (2) such notice per calendar year; after the second five (5) business day notice in any calendar year, a default shall occur for a default in the payment of any installment of rent, additional rent,
or other sum herein specified and such default shall continue for five (5) business days after the date said payment is due; or 

  

	 	(b)	The LESSEE shall default in the observance or performance of any other of the LESSEE’S covenants, agreements, or obligations hereunder and such default shall not be corrected within thirty (30) days after
written notice thereof plus such reasonable additional time, not to exceed ninety (90) days, as may be necessary to cure the default so long as LESSEE diligently proceeds to cure the default and continues to take all steps necessary to complete
the same; or 

  

	 	(c)	The LESSEE shall be declared bankrupt or insolvent according to law, or, if any assignment shall be made of LESSEE’S property for the benefit of creditors, or if the LESSEE shall be otherwise dissolved,









 then the LESSOR shall have the right thereafter, while such default continues, to re-enter and
take complete possession of the Leased Premises, to declare the term of this lease ended, and remove the LESSEES effects, without prejudice to any remedies which might be otherwise used for arrears of rent or other default. The LESSEE shall
indemnify the LESSOR against all loss of rem and other payments which the LESSOR may incur by reason of such termination during the residue of the term, or the LESSOR may elect to be indemnified for loss of rent and other sums due under this lease
by a lump sum payment representing the then present value of the amount of all sums which would have been paid in accordance with this lease for the remainder of the term minus the then present value of the aggregate market rate, as defined below,
and additional charges payable for the Leased Premises for the remainder of the term, taking into account reasonable projections of vacancy and time required to re-lease the Leased Premises, For purposes hereof, market rate shall be the then current
effective rate of rent (adjusted, if necessary, to reflect any free rent or comparable concessions), being charged for comparable space in comparable buildings. For the purposes of calculating the rent which would have been paid hereunder for the
lump sum payment calculation described herein, the most recent full year’s tax and operating expense payments shall be deemed constant for each year thereafter. The Federal Reserve discount rate (or equivalent) plus 3% shall be used in
calculating present values, If the LESSEE shall default, after reasonable notice thereof, in the observance or performance of any conditions or covenants on LESSEES part to be observed or performed under or by virtue of any of the provisions in any
article of this lease, the LESSOR, without being under any obligation to do so and without thereby waiving such default, may elect to remedy such default for the account and at the expense of the LESSEE. If the LESSOR makes any expenditures or
incurs any obligations for the payment of money in connection therewith, including but not limited to, reasonable attorney’s fees in instituting, prosecuting or defending any action or proceeding, such sums paid or obligations insured, with
interest at the rate of 12 per cent per annum and costs, shall be paid to the LESSOR by the LESSEE as additional rent. It is expressly understood and agreed that the LESSEE’S obligation to pay rent, and any and all additional charges, is
independent of any obligation or covenant entered into by the LESSOR. 
 (B) If LESSOR shall default in the performance or observance of its
agreements contained in Article 11B hereof or the one (1) year warranty for LESSOR’S Work as stated in Exhibit B hereto, and shall not cure such default within thirty (30) days after written notice from LESSEE specifying the default
(or shall not within said period commence to cure such default, and thereafter prosecute the curing of such default to completion with due diligence), LESSEE may, at its option, at any time thereafter cure such default for the account of LESSOR, and
any amount paid in so doing shall (except to the extent that LESSEE is required to reimburse the same to LESSOR pursuant to said paragraph) be deemed paid or incurred for the account of LESSOR, and LESSOR agrees to reimburse LESSEE therefore or save
LESSEE harmless therefrom; provided that LESSEE may cure any such default as aforesaid prior to the expiration of said waiting period but after written notice to LESSOR, if the curing of such default prior to the expiration of said waiting period is
reasonably necessary to protect real estate or LESSEE’S interest therein, or to prevent injury or damage to persons or property. LESSOR shall pay such reimbursement to LESSEE within thirty (30) days from demand. Such demand shall be
accompanied by an itemized bill therefore in reasonable detail. 








	20.	NOTICE:

	21.	SURRENDER: 

 The LESSEE shall at the expiration or other termination of this lease
remove all of LESSEE’S goods and effects from the Leased Premises, (including, without hereby limiting the generality of the foregoing, all signs and lettering affixed or painted by the LESSEE, either inside or outside the Leased Premises), but
excluding anything constituting LESSOR’S Work as set forth on Exhibit B. LESSEE shall deliver to the LESSOR the Leased Premises and all keys, locks thereto, and other fixtures connected therewith and all alterations and additions made to or
upon the Leased Premises, in good condition, reasonable wear and tear, damage by fire or other casualty, eminent domain, default by LESSOR or by the negligent or willful acts or omissions of LESSOR, its officers, managers, employees, agents,
contractors and invitees only excepted. In the event of the LESSEE’S failure to remove any of LESSEE’S property from the premises upon the expiration or other termination of the lease, LESSOR is hereby authorized, without liability to
LESSEE for loss or damage thereto, and at the sole risk of LESSEE, to remove and store any of the property at LESSEE’S expense, or to retain same under 







 
LESSOR’S control or to sell at public or private sale, without notice any or all of the property not so removed and to apply the net proceeds of such sale to the payment of any sum due
hereunder, or to destroy such property. 
 In the event that LESSEE continues to occupy, control or remain in any part of the Leased Premises
beyond the expiration or earlier termination of the Term of this lease, including any extensions thereto, such holding over shall not be deemed to create any tenancy, but the LESSEE shall be a Tenant at Sufferance only and shall be liable for all
loss, damage or expenses incurred by the LESSOR. All other terms of this lease shall apply, except that use and occupancy payments shall be due in full monthly installments which shall be paid to LESSOR at the times and manner determined by the
LESSOR, in advance and in an amount equal to the greater of one and a half times of either of the following: (i) base rent, additional rent and other sums due under the lease, including any extensions thereto, immediately prior to termination,
or (ii) the reasonable fair market rent for the Leased Premises. It is expressly understood and agreed that such extended occupancy is a Tenancy at Sufferance only, solely for the benefit and convenience of the LESSEE and is of greater rental
value. If LESSEE continues to occupy, control or remain in all or any part of the Leased Premises beyond noon of the last day of any monthly rental period, said action shall constitute LESSEE’S occupancy for an entire additional month, and
increased payment as provided by this section, shall be due and payable immediately in advance. LESSOR’S acceptance of any payments from LESSEE during such extended occupancy shall not alter LESSEE’S status as a Tenant at Sufferance. 

 

	22.	LATE FEES: 

 LESSEE agrees that because of actual damages for a late payment or a
dishonored check are difficult to fix or ascertain, but recognizing that damage and injury result therefore, LESSEE agrees that if payments of rent and other obligations are not received in hand by LESSOR five (5) business days after the date
it is due, LESSEE agrees to pay liquidated damages equal to five percent (5%) of the total delinquent amount owed. The postmark on the payment, received plus two (2) days, shall be conclusive evidence of whether the payment is delinquent.
However, LESSOR is not responsible for late deliveries by U.S. Mail. LESSEE agrees to pay a liquidated damage of $25.00 for each dishonored check. In the event that two or more of the LESSEES checks are dishonored in a 12 month period, the LESSOR,
in addition to other Rights, shall have the right to demand payment by Certified Check or Money Order. 
  

	23.	BROKERAGE: 

 LESSEE warrants and represents, to the best of LESSEE’S
knowledge, to the LESSOR that the only brokers entitled to a brokerage fee in connection with showing the Leased Premises or the property of which the Leased Premises is a part, or otherwise procuring or obtaining a tenant for the benefit of the
LESSOR is as follows: Grubb & Ellis, Meredith and Grew. LESSOR shall pay a commission, which will be split between Grubb & Ellis and Meredith and Grew pursuant to the terms of a separate agreement. LESSEE shall hold harmless and
indemnify the LESSOR from any loss, cost, damage 







 
and expense, including reasonable attorney’s fees incurred by LESSOR for a commission or finder’s fee as a result of the falseness of this representation. LESSEE hereby assumes and
shall be solely responsible and liable for any and all cost and expense other than the above-mentioned agreed upon amount to be split between Grubb & Ellis and Meredith and Grew. 

 

	24.	EARLY ACCESS: 

 Provided the LESSEE is not in default hereunder and the LESSEE
does not interfere with the LESSOR’S Work (including, but not limited to LESSOR’S ability to obtain approvals, permits, or otherwise comply with applicable permitting or regulatory authorities) or the tenant improvements, the LESSEE will
be allowed, upon reasonable notice to LESSOR, reasonable access to the Leased Premises thirty (30) days prior to the Commencement Date to permit LESSEE to assess -and install network infrastructure and install its furniture and equipment.
During such access, LESSEE shall be bound by all of the obligations of the LESSEE under the lease, including any and all insurance requirements, but, provided that said access is solely for the purpose noted above, excluding the- payment of base
rent, real estate taxes and operating costs as defined in Exhibit E hereto during said early access period. 
  

	25.	OPTION TO EXTEND: 

 Provided the LESSEE is not in default hereunder, LESSEE shall
have two (2) five (5) year options to extend the lease term at a rent equal to the market rate for equivalent office space in similarly located buildings within the Waltham/Lexington market (“Market Rate”). LESSEE must give
LESSOR written notice it is exercising its extension option no later than nine (9) months prior to the expiration of the then current lease term. In the event LESSEE notifies LESSOR as provided herein, then within fifteen (15) days of
receiving LESSEE’S notice, the LESSOR shall notify the LESSEE of the LESSOR’S determination of the Market Rate for the extended term, then the LESSEE shall, within fifteen (15) days of receiving the LESSOR’S rent rate in
accordance with the above, either: 
 (1) deliver a written notice accepting the rent rate, and thereafter the parties shall fully execute a
mutually agreeable lease amendment within thirty (30) days from the date the LESSOR receives LESSEE’S written notice accepting the rent rate; or 

(2) deliver a written notice withdrawing its exercise of the option; or 

(3) deliver a written notice disagreeing with the LESSOR’S rent rate for the extended term, said notice to include alternate rent rates
for the extended term, and the LESSOR and LESSEE shall attempt to agree upon the rent rate using their best good-faith efforts. If LESSOR and LESSEE fail to reach an agreement within fifteen (15) days following LESSOR’S receipt of
LESSEE’S above-mentioned written notice of disagreement (“Outside Agreement Date”), then: 
  

	 	(i)	 LESSOR and LESSEE shall each appoint, at their own cost and expense, within fifteen (15) days of the Outside Agreement Date, one arbitrator who
shall by profession be a current commercial real estate broker or appraiser of comparable properties in the immediate vicinity of the Leased Premises, and who has been active in such field over the last five (5) years. The two
(2) arbitrators shall 










	 	
confer and within thirty (30) days from the date the last arbitrator was appointed, shall each recommend a market rate in writing to both parties. In the event their recommendation is joint
or equal, then this recommendation shall be the Market Rate for the extended term; and 

  

	 	(ii)	In the event the arbitrators recommendation differs by five percent (5%) or less, then the average shall be the Market Rate for the extended term; and 


 

	 	(iii)	In the event the arbitrators recommendation differs by more than five percent (5%), then the two arbitrators so appointed shall, within five (5) business days of the date of the last written recommendation, agree
upon and appoint a third arbitrator who shall be qualified under the same criteria set forth hereinabove for qualification of the initial two arbitrators. The third arbitrator shall, within fifteen (15) days of his/her appointment, recommend a
market rate in writing to both parties, and the two (2) closest of the three (3) recommendations shall then be averaged to establish the Market Rate for the extended term; and 


 

	 	(iv)	If either LESSOR or LESSEE fails to appoint an arbitrator within fifteen (15) days after the applicable Outside Agreement Date, the arbitrator appointed by one of them shall reach a decision, notify LESSOR and
LESSEE thereof, and such arbitrator’s decision shall be binding upon LESSOR and LESSEE; and 

  

	 	(v)	If the two arbitrators fail to agree upon and appoint a third arbitrator, or both parties fail to appoint an arbitrator, and this matter has not been otherwise resolved, then the appointment of the third arbitrator or
any arbitrator shall be dismissed and the matter to be decided shall be forthwith submitted to arbitration under the provisions of the American Arbitration Association, but subject to the instructions set forth in this Article 25; and


  

	 	(vi)	The cost of arbitration, as well as the above-mentioned third arbitrator, shall be paid by LESSOR and LESSEE equally. 


In the event the rent for the extended term is established in accordance with the above, then the lease agreement shall automatically be
extended five (5) years from the date the Lease would have expired had the option to extend not been exercised. LESSEE shall be responsible for increasing or decreasing its letter of credit so that same is an amount equivalent to three
(3) month’s base rent. All other terms and provisions under the Lease, other than LESSOR’S Work, and rent holidays, shall continue through the extended lease term. In the event the LESSEE does not provide written notice of its intent
to extend as provided in this Article 25, the LESSEE shall be deemed to have waived its option to extend the lease term and this Lease shall terminate upon the expiration of the then current term. 

 

	26.	SIGNAGE: 

 LESSEE may, subject to LESSOR’S review and approval, not to be
unreasonably withheld, conditioned or delayed, install monument or building directory signage which conforms with the professional character and nature of the building of which the Leased Premises is a part and the neighboring buildings. LESSEE is
solely responsible for obtaining, at its own expense, all necessary approvals from the appropriate municipal, regulatory or other authority. 








	27.	INSPECTION: 

 LESSEE may conduct an inspection of the Leased Premises prior to the
Commencement Date to confirm that the roofs, and all building systems, are in good working order. 
  

	28.	QUIET ENJOYMENT: 

 LESSOR covenants that upon LESSEE’S paying the rent and
performing its obligations hereunder, LESSEE shall quietly have and enjoy the Leased Premises during the term, as same may be extended, without hindrance or molestation from LESSOR. 

 

	29.	MEMORANDUM OF LEASE: 

 Neither LESSOR nor LESSEE shall record this Lease. LESSOR
and LESSEE shall at any time, at the request of either one, promptly execute a memorandum of lease which satisfies the requirements of the applicable statute in the-Commonwealth of Massachusetts and-either party may record the same at its own time
and expense. 
  

	30.	ESTOPPEL CERTIFICATE: 

 Within fifteen (15) days after a written request
therefor, either party shall, at its own time and expense, execute and deliver to the other a written certificate stating (a) whether this lease has been modified or amended; (b) whether this lease (as so modified or amended) is in full
force and effect; (c) the date to which rent has been paid; and (d) whether the other party is in default, and if so, the nature of such default.

	 	(c)	LESSEE shall indemnify, defend and save harmless LESSOR, its officers, directors, employees, contractors, servants and agents, from and against all reasonable and actual: loss, costs, damages, claims, proceedings,

	 	(A)	LESSOR represents that LESSOR, subject to an existing mortgage, is the owner in fee of the Leased Premises; that there are presently, to the best of the LESSOR’S knowledge, no matters of record which would
