CONSENT TO
SUBLEASE

EDGEWATER OFFICE PARK


 


THIS CONSENT TO SUBLEASE
(“Consent”) dated as of ____________________, 2016, is made with reference to that certain Sublease Agreement
(the “Sublease”) dated 2016 and attached hereto as Exhibit A, by and between SDL XyEnterprise LLC, a Delaware limited
liability company, formerly known as XyEnterprise Inc., with an address at 201 Edgewater Drive, Suite 225, Wakefield, Massachusetts
01880 (“Tenant”) and Biofrontera AG, a Delaware corporation with an address at 201 Edgewater Drive, Wakefield,
Massachusetts 01880 (“Subtenant”), and is entered into by and among Tenant, Subtenant, and 101 Edgewater LLC,
a Delaware limited liability company (together with its successors and assigns, “Landlord”), with addresses
in care of Hobbs Brook Management, LLC, 225 Wyman Street Waltham, Massachusetts 02451-1209, Attention: Real Estate Manager, with
reference to the following facts:


 


(A)         Landlord
and Tenant, or their respective predecessors in interest, are the parties to that certain Office Lease dated as of April 30, 2012,
as amended by First Amendment to Lease dated March 17, 2014 (as heretofore or hereafter amended from time to time, the “Master
Lease”) with respect to the Premises (as defined in the Master Lease) located in the building known as 201 Edgewater
Drive, Wakefield, Massachusetts (the “Building”);


 


(B)         Tenant
and Subtenant wish to enter into the Sublease, with respect to a portion of the Premises, as described in the Sublease and being
known as the Additional Premises in the Master Lease, containing approximately 5,362 square feet of Rentable Floor Area located
on the first floor of the Building (the “Sublease Premises”);


 


(C)         The
Master Lease provides, inter alia, that Tenant may not enter into the Sublease without Landlord’s prior written consent;
and


 


(D)         Tenant
and Subtenant have presented the fully executed Sublease to Landlord in connection with Tenant’s request for such consent,
upon all of the terms and conditions hereinafter set forth.


 


NOW, THEREFORE, for
good and valuable consideration, the parties agree as follows:


 


1.          Tenant
and Subtenant represent and warrant to Landlord that the copy of the Sublease attached hereto as Exhibit A is a true and
complete copy of the Sublease and that the same represents the entire agreement between Tenant and Subtenant with respect to the
sublease of the Sublease Premises. Landlord hereby consents to Tenant entering into the Sublease upon the terms and conditions
set forth below.


 


2.          This
Consent shall not release Tenant from any existing or future duty, obligation or liability to Landlord pursuant to the Master Lease,
nor shall this Consent change, modify or amend the Master Lease in any manner, notwithstanding anything to the contrary in the_
Sublease. Without limiting the generality of the foregoing and notwithstanding anything to the contrary in the Sublease, (a) Tenant
shall obtain Landlord’s prior written approval of any other subleases, assignments or other dispositions of Tenant’s
interest in the Master Lease or the Premises or any portion thereof (except as may be expressly set forth in the Master Lease)
or of Subtenant’s interest in the Sublease or the demised premises thereunder or any portion thereof, (b) this Consent shall
not constitute Landlord’s consent to any alteration of the Sublease Premises or the Premises, and (c) any provision of the
Sublease that, directly or indirectly, purports to expand the uses permitted under the Master Lease beyond those set forth in the
Master Lease, to grant to Subtenant rights that are greater than those granted to Tenant under the Master Lease or in conflict
with any provision of the Master Lease or this Consent, or otherwise to change, modify or amend the Master Lease in any manner
shall be deemed void and without force or effect.


 




     


     


    

 


3.          (a)          In
the event of a Master Lease Termination (as hereinafter defined), at the written request and sole option of Landlord, Subtenant
agrees to attorn to Landlord and to recognize Landlord as Subtenant’s landlord under the Sublease, upon the terms and conditions
and at the rental rate specified in the Sublease, and for the then remaining term of the Sublease, except that Landlord shall not
be bound by any provision of the Sublease that in any way increases Landlord’s duties, obligations or liabilities to Subtenant
beyond those owed to Tenant under the Master Lease or by any provision that grants or attempts to grant Subtenant any rights, privileges
or benefits greater than those possessed by Tenant under the Master Lease. Subtenant hereby waives any provisions of applicable
law that may permit Subtenant (i) to terminate the Sublease other than pursuant to its terms or (ii) to surrender possession of
the Sublease Premises in the event of a Master Lease Termination; and Subtenant hereby agrees that the Sublease shall not be affected
in any way whatsoever by a Master Lease Termination in the event Landlord requests Subtenant’s attornment to and recognition
of Landlord except as set forth herein. In the event of a Master Lease Termination as to which Landlord does not so request Subtenant’s
attornment to and recognition of Landlord as set forth above, the Sublease shall terminate.


 


In no event shall Landlord
ever (i) be liable to Subtenant for any act, omission or breach of the Sublease by Tenant, (ii) be subject to any offsets or defense
that Subtenant might have against Tenant, (iii) be bound by any rent or additional rent that Subtenant might have paid in advance
to Tenant, or (iv) be bound to honor any rights of Subtenant in any security deposit placed by Subtenant except to the extent Tenant
has specifically assigned and turned over such security deposit to Landlord as set forth below.


 


Tenant hereby agrees
that in the event of a Master Lease Termination, Tenant shall immediately pay or transfer to Landlord any security deposits, rent,
or other sums then held by Tenant in connection with the subleasing of the Sublease Premises, unless at that time the Sublease
shall also be terminated, with the Subtenant having vacated the Sublease Premises, and there is no outstanding rent or other sums
due to Landlord by either Tenant or Subtenant. Subtenant hereby agrees that under no circumstances whatsoever shall Landlord be
held in any way responsible or accountable for any security deposit or any sums paid by Subtenant to Tenant except to the extent
that Landlord has actually received such sums from Tenant and has acknowledged their source, and Subtenant shall have no claim
to any security or other deposit made by Tenant under the Master Lease.


 


(b)          “Master
Lease Termination” means any event that, by voluntary or involuntary act or by operation of law, might cause or permit
the Master Lease (or Tenant’s right to possess the Premises under the Master Lease) to be terminated, expire, be canceled,
be foreclosed against, or otherwise come to an end, including but not limited to (1) a default by Tenant under the Master Lease
or any of the terms and provisions hereof, in each case beyond any applicable notice and cure period; (2) foreclosure proceedings
brought by the holder of any mortgage or deed of trust to which the Master Lease is subject, unless otherwise expressly agreed
to by Tenant and any such holder pursuant to any non-disturbance and/or recognition agreement or otherwise; (3) the termination
of Tenant’s leasehold estate by dispossession proceeding or otherwise; or (4) the expiration or termination of the Master
Lease in accordance with its terms.


 




     


     


    

 


4.          Subtenant
shall be liable to Landlord, jointly and severally with Tenant, to the extent of the obligations undertaken by or attributable
to Subtenant under the Sublease, for the performance of Tenant’s agreements under the Master Lease. Landlord may elect to
receive directly from Subtenant all sums due or payable to Tenant by Subtenant pursuant to the Sublease, and upon receipt of Landlord’s
notice, following a Master Lease Termination (and not otherwise), Subtenant shall thereafter pay to Landlord any and all sums becoming
due or payable under the Sublease and Tenant shall receive from Landlord a corresponding credit for such sums actually received
by Landlord against any and all payments then owing from Tenant under the Master Lease. Neither the service of such written notice
nor the receipt of such direct payments shall cause Landlord to assume any of Tenant’s duties, obligations and/or liabilities
under the Sublease, nor shall such event impose upon Landlord the duty or obligation to honor the Sublease in the event of a Master
Lease Termination, nor subsequently to accept any purported attornment by Subtenant not elected by Landlord pursuant to Section
3(a) hereof.


 


5.          Subtenant
hereby acknowledges that it is familiar with all of the terms and provisions of the Master Lease and agrees not to do or omit to
do anything that would cause Tenant to be in breach of the Master Lease. Any such act or omission shall also constitute a breach
of the Master Lease and this Consent and shall entitle Landlord to recover any damage, loss, cost, or expense that it thereby suffers
from Tenant and Subtenant, jointly and severally. Without limiting the generality of the foregoing, Subtenant shall comply with
and be subject to the provisions of the Master Lease regarding Tenant’s insurance (to the extent the same relate to the Sublease
Premises) and waivers of subrogation and, upon Landlord’s request from time to time, shall provide Landlord with such evidence
of such compliance. To the extent that any provision of the Sublease is inconsistent with the provisions of the Master Lease, Subtenant
agrees that it shall be bound by any stricter provision set forth in the Master Lease.


 


6.          Tenant
and Subtenant, jointly and severally, shall be liable to reimburse Landlord for any expenses, including reasonable attorneys’
fees, incurred in enforcing any of the terms or provisions of this Consent.


 


7.          No
expansion, extension, or termination of the Sublease that is not expressly set forth in the Sublease, and no modification of the
Sublease, will be binding upon Landlord without Landlord’s prior written consent thereto. If the Master Lease has been guaranteed,
then Tenant shall deliver to Landlord a written approval of the Sublease and this Consent by each such guarantor as evidenced by
the Joinder to this Consent.


 


8.          The
agreements contained herein constitute the entire understanding between the parties with respect to Landlord’s consent to
the Sublease, and shall supersede any prior agreements, written or oral with respect to such consent. Tenant and Subtenant warrant
and agree that neither Landlord nor any of its agents or other representatives have made any representations concerning the Premises,
their condition, the Sublease, or the Master Lease.


 




     


     


    

 


9.          Any
notice, approval, consent and other like communication hereunder shall be effective only if given in writing and shall be deemed
duly served (i) if and when hand delivered, (ii) the third day following such mailing if and when mailed prepaid certified or registered
mail, or (iii) the next business day if sent by national recognized overnight courier which provides evidence of delivery (in any
case, whether or not accepted for delivery), in each case addressed to the parties at the addresses set forth in this Consent (or
to the extent any such address(es) are not so listed, then to the Landlord at the Landlord’s notice address applicable under
the Master Lease, or to Tenant or Subtenant at the address of the Premises or of the Sublease Premises, respectively). Any party
may change its address for notice by giving notice in the manner hereinabove provided.


 


10.         Notwithstanding
anything to the contrary in the Sublease, (a) neither the Master Lease, the Sublease nor this Consent shall be deemed, nor are
they intended, to grant to Subtenant any rights whatsoever against Landlord, (b) Subtenant hereby acknowledges and agrees that
its sole remedy for any alleged or actual breach of its rights in connection with the Sublease shall be solely against Tenant,
that it is not a third party beneficiary under the Master Lease, and that it is not entitled to assert, against Landlord, any of
Tenant’s rights under the Master Lease or any claims arising under the Sublease, whether in its own right, on behalf of Tenant,
by a purported assignment of Tenant’s rights under the Master Lease to Subtenant, or otherwise, and (c) Tenant and Subtenant
shall be jointly and severally liable to Landlord for all charges for services from time to time rendered by Landlord or its agents
to the Sublease Premises or to Subtenant in connection with the Sublease Premises, whether the same are for ordinary services (such
as electricity), separately reimbursable services (such as after-hours HVAC or other special or extra services), or otherwise,
whether the same are requested by Tenant or Subtenant or their respective representatives, and whether or not the same are permitted
or prohibited by, or referenced in, the Master Lease or the Sublease, and Tenant and Subtenant shall be responsible, as between
themselves, for allocating responsibility for such charges. Landlord may in its sole discretion disregard, refuse, or decline to
respond to any requests from time to time made by Subtenant directly to Landlord for any such services, approvals, or otherwise.


 


11.         Tenant
and Subtenant agree: (a) jointly and severally, to indemnify and hold Landlord harmless from and against any loss, cost, expense,
damage, or liability, including reasonable attorneys’ fees, incurred as a result of a claim by any person or entity (i) that
it is entitled to a commission, finder’s fee or like payment in connection with the Sublease or (ii) relating to or arising
out of the Sublease or any related agreements or dealings; and (b) that Section 14 of the Sublease shall govern their respective
obligations to one another regarding any such brokers.


 


12.         Tenant
shall promptly pay Landlord’s expenses incurred in connection with Tenant’s request for consent of this Sublease, as
and to the extent provided in the Master Lease.


 




     


     


    

 


13.         Subtenant
hereby warrants, represents and certifies to Landlord that (a) Subtenant is duly organized, validly existing and in good standing
under the laws of the jurisdiction in which such entity was organized; (b) Subtenant has the authority to own its property and
to carry on its business as contemplated under the Sublease; (c) Subtenant is in compliance with all laws and orders of public
authorities applicable to Subtenant, (d) Subtenant is not acting, directly or indirectly, for or on behalf of any person, group,
entity, or nation named by any Executive Order or the United States Treasury Department as a terrorist, “Specially Designated
National and Blocked Person”, or other banned or blocked person, group, entity, nation, or transaction pursuant to any law,
order, rule, or regulation that is enforced or administered by the Office of Foreign Assets Control or other governmental agency
and that it is not engaged in this transaction, directly or indirectly, on behalf of, or instigating or facilitating this transaction,
directly or indirectly, on behalf of any such person, group, entity, or nation; (e) Subtenant has duly executed and delivered this
Consent; (f) the execution, delivery and performance by Subtenant of this Consent (i) are within the powers of Subtenant, (ii)
have been duly authorized by all requisite action, (iii) will not violate any provision of law or any order of any court or agency
of government, or any agreement or other instrument to which Subtenant is a party or by which it or any of its property is bound,
and (iv) will not result in the imposition of any lien or charge on any of Subtenant’s property, except by the provisions
of this Consent; and (g) the Consent is a valid and binding obligation of Subtenant in accordance with its terms. Subtenant hereby
agrees to defend, indemnify, and hold harmless Landlord from and against any and all claims, damages, losses, risks, liabilities,
and expenses (including attorneys’ fees and costs) arising from or related to any breach of the foregoing warranty, representation,
and certification. The provisions of this Section 13 shall survive the expiration or earlier termination of the term of the Sublease.


 


14.         Landlord
shall not be considered to have consented to the Sublease unless and until this Consent is executed and delivered by Landlord,
Tenant, and Subtenant and approved by the holder of any mortgage on the Building having a right to approve the Sublease (Landlord
hereby representing and warranting to Tenant and Subtenant that no such holder exists as of the date of this Consent). The submission
of this Consent to Tenant or Subtenant for review or for execution, or any course of negotiations or communications with respect
to the proposed Sublease, shall not constitute or be deemed to constitute Landlord’s consent to the Sublease, an undertaking
to provide such consent, a waiver of any right of Landlord to request and review financial information, references, and other information
regarding the Subtenant, its business and principals, and proposed activities in the Subleased Premises, or to recapture or terminate
the Lease as to the Sublease Premises, or other undertaking to provide such consent or waiver. Any liability of Landlord to Tenant
under or in connection with this Consent, and any liability of Landlord to Subtenant, including without limitation liability under
or in connection with the Sublease or arising in any way from Subtenant’s use or occupancy of the Sublease Premises, shall
be limited to the same extent as Landlord’s liability to Tenant is limited under the Master Lease.


 


15.         This
Consent shall be binding upon and shall inure to the benefit of Landlord, Tenant, and Subtenant and their respective successors
and permitted assigns.


 


16.         This
Consent may be executed in multiple counterparts, each of which shall be deemed an original and all of which together shall constitute
a single agreement, and shall be governed by the laws of The Commonwealth of Massachusetts.

Office Lease dated as of April 30, 2012, by and between 101 Edgewater LLC, a Delaware limited liability company (“Landlord”),
and Sublandlord, as tenant, as amended by that First Amendment to Lease dated as of March 17, 2014 (as amended, the “Underlying

WHEREAS, all capitalized
terms used herein without definition shall have the same meaning as set forth in the Underlying Lease; and


 


WHEREAS, Sublandlord
desires to sublease to Subtenant the approximately 5,362 rentable square foot portion of the Premises referred to in the First
Amendment to Lease as the “Additional Premises” and shown on the plan attached hereto as Exhibit A-1
(the “Subleased Premises”), and Subtenant is willing to sublet the Subleased Premises from Sublandlord on the
terms and conditions hereinafter set forth.


 


NOW, THEREFORE, in
consideration of the mutual covenants and agreements hereinafter set forth, it is hereby agreed by and between the parties hereto
as follows:


 


1.          PREMISES.


 


1.1           Sublease.
Sublandlord hereby subleases unto Subtenant, and Subtenant hereby takes and hires from Sublandlord, the Subleased Premises, subject
to the terms, conditions and provisions hereof. Subtenant shall have all the rights, privileges and benefits of the “Tenant”
of such Underlying Lease pertaining to the Subleased Premises except as herein specifically limited or denied, and the same are
hereby granted and conveyed to Subtenant from Sublandlord for the full Term hereof.


 


1.2           Condition
of Premises. Subject to Sublandlord’s obligation to deliver the Subleased Premises to Subtenant in so-called “broom
clean” condition and free of all occupants, Subtenant accepts the Subleased Premises and the Personal Property (as defined
below) therein in “as-is” condition on the Sublease Commencement Date (as defined below). Subtenant acknowledges and
agrees that Sublandlord has no obligation and has made no promises to alter, remodel, improve, renovate, repair or decorate the
Subleased Premises, or any part thereof, or to provide any allowance for such purposes, and that no representations respecting
the condition of the Subleased Premises have been made by Sublandlord to Subtenant.


 




     


     


    

 


2.          TERM.


 


The term of this Sublease
shall commence upon the full execution and delivery of this Sublease by the Sublandlord and Subtenant and receipt of the Landlord’s
consent referred to in Section 12 (the “Sublease Commencement Date”) and end on June 15, 2019 (the “Term”),
unless the Term may be sooner terminated as set forth herein. Subtenant shall have the right to occupy the premises beginning on

and agrees to pay rent to Sublandlord to the address noted in Section 3.2, at the following rates and time periods:


 


3.1           Rent.
Subtenant shall pay to Sublandlord fixed rent for the Premises (“Base Rent”), in advance, on the first day of
each and every calendar month during the Term hereof and pro-rated for the fraction of any month, without offset, deduction, notice
or demand, in the following amounts:


 


	Period	 	Monthly Base Rent	 
	Sublease Commencement Date to May 31, 2017	 	$	7,372.75	 
	June 1, 2017 to May 31, 2018	 	$	7,819.58

(a)           Operating
Expenses. 5.44% of Landlord’s Operating Expenses in each calendar year or portion thereof in the Term in excess of
Landlord’s Operating Expenses for Calendar Year 2016, which percentage is based on the ratio of the (i) rentable square footage
of the Subleased Premises (i.e., approximately 5,362 rentable square feet) to (ii) Rentable Floor Area of Building (as defined
in the Underlying Lease) (i.e., 98,583 square feet);


 


(b)           Taxes.
5.44% of Landlord’s Taxes in each tax fiscal year or portion thereof in the Term in excess of Landlord’s Taxes for

Premises (i.e., approximately 5,362 rentable square feet) to (ii) Rentable Floor Area of Building (i.e., 98,583 square feet); and


 


(c)           Electric.
22.23% of the electricity billed to the Premises, provided that if Subtenant’s use of electricity shall exceed normal office
use as reasonably designated by Sublandlord, Subtenant shall pay an additional amount therefor, as reasonably estimated and billed
by Sublandlord, which percentage is based on the ratio of the (i) rentable square footage of the Subleased Premises (i.e., approximately
5,362 rentable square feet) to (ii) rentable square footage of the Premises (i.e., approximately 24,125 square feet).


 




    	 	2	 



     


    

 


3.3           Address
for Payment. All Rent and Additional Rent shall be paid to Sublandlord at the address set forth in the Notice section or
such other address as Sublandlord may designate in writing.


 


3.4           Security
Deposit. Subtenant shall deposit with Sublandlord a security deposit in the amount of $14,745.50 (the “Security
Deposit”), which sum Sublandlord shall retain as security for the performance by Subtenant of each of its obligations
hereunder. If at any time Subtenant fails to perform any of its obligations under this Sublease, including the payment of Rent
or other payment obligations, Sublandlord may, at its option, apply the Security Deposit (or any portion thereof) to cure Subtenant’s
default or to pay for damages caused by Subtenant’s default, and Subtenant shall immediately pay to Landlord the amount so
applied to replenish the Security Deposit. If this Sublease has been terminated, then Sublandlord may apply the Security Deposit
(or any portion thereof) against the damages incurred as a consequence of Subtenant’s breach. The application of the Security
Deposit shall not limit Sublandlord’s remedies for default under the terms of this Sublease. Unless Sublandlord uses the
Security Deposit to cure a default of Subtenant, to pay damages for Tenants’ breach of the Sublease or to restore the Premises
to the condition to which Subtenant is required to leave the Premises upon expiration or any termination of the Sublease, then
Sublandlord shall, within thirty (30) days after the termination of this Sublease, refund to Subtenant any funds remaining in the
Security Deposit.


 


4.          USE.


 


Subtenant shall have
the right to use the Premises for the Permitted Uses set forth in the Underlying Lease, and for no other purpose.


 


5.          UTILITIES.


 


Except as provided
in Section 3.2 above, Subtenant shall be responsible for all charges for any utility, if any, separately metered or submetered
to the Subleased Premises and consumed by Subtenant in or upon the Subleased Premises during the Term of this Sublease.


 


6.          ASSIGNMENT
AND SUBLEASING.


 


Subtenant shall not
have the right to assign Subtenant’s interest in this Sublease or sublease all or any portion of the Subleased Premises during
the Term, by operation of law or otherwise, without the prior written consent of Landlord and Sublandlord.


 


7.          SUBORDINATION
OF SUBLEASE.


 


7.1           Subordination
of Sublease. It is understood that Sublandlord is not the fee owner of the Premises, but has acquired its interest therein
solely through the Underlying Lease. This Sublease is subject to the provisions of the Underlying Lease and subordinate thereto.
In the event that the Underlying Lease shall be cancelled or terminated by Landlord, the Term of this Sublease shall automatically
terminate as of the date of such cancellation or termination of the Underlying Lease by Landlord, and Sublandlord shall not be
liable in any way or to any extent to Subtenant for such termination or cancellation or for any damages or losses incurred or claimed
to be incurred by Subtenant as a result thereof.


 




    	 	3	 



     


    

 


7.2           Attornment.
Notwithstanding anything to the contrary contained herein, in the event of a termination of the Underlying Lease, and re-entry
and dispossession of Sublandlord by Landlord, Landlord may, at its option, take over all right, title and interest of Sublandlord
under this Sublease and Subtenant shall, at Landlord’s option, attorn to Landlord, pursuant to the terms of this Sublease,
except that Landlord shall not:


 


(a)           be
liable for any previous act or omission of Sublandlord under this Sublease;


 


(b)           be
subject to any offset, not expressly provided in this Sublease, which theretofore accrued to Subtenant against Sublandlord;


 


(c)           be
bound by any modification of this Sublease made subsequent to the date hereof or by any previous prepayment of more than one month’s
rent unless previously approved by Landlord;


 


(d)           be
hound by any covenant to undertake or complete any construction of the Subleased Premises or any portion thereof demised by this
Sublease; or


 


(e)           be
bound by any obligation to make any payment to or on behalf of Subtenant.


 


8.          INCORPORATION
OF UNDERLYING LEASE.


 


8.1           Sublease

and conditions of the Underlying Lease and such terms, covenants and conditions are incorporated herein by reference and made a

The words “Landlord”
and “Tenant” as utilized in the provisions of the Underlying Lease incorporated herein shall be deemed for the purposes
of this Sublease to refer to Sublandlord and Subtenant respectively, it being understood and agreed that, subject to the provisions
of Section 8.3 below, Sublandlord will not be acting as, or assuming any of the responsibilities of, Landlord, and all references
in the Underlying Lease to Landlord-provided services or Landlord insurance requirements, and any other references which by their
nature relate to the owner or operator of the building, rather than to a tenant of the building subleasing space to a subtenant,
shall continue to be references to Landlord and not to Sublandlord. The words, “this Lease” as utilized in the provisions
of the Underlying Lease incorporated herein shall be deemed for the purposes of this Sublease to refer to this Sublease. In all
provisions of the Underlying Lease requiring the approval or consent of the “Landlord,” Subtenant shall be required
to obtain the approval or consent of Sublandlord (which may be conditioned on Sublandlord’s ability to obtain the approval
or consent of Landlord pursuant to the Underlying Lease).


 


8.2           Conflict
with Underlying Lease. If any of the provisions of this Sublease are at variance or in conflict with the provisions of
the Underlying Lease due to an express deletion, modification or alteration of such provisions herein, the provisions of this Sublease
shall govern and control, as between Sublandlord and Subtenant only, and Landlord shall not be bound thereby.


 


8.3           Sublandlord’s
Obligations. Notwithstanding anything to the contrary in this Sublease or the Underlying Lease, Sublandlord shall have
no obligation to perform any of the terms, covenants and conditions contained in the Underlying Lease to be performed by Landlord.
Without limiting the foregoing, Sublandlord shall have no obligation to provide any or all of the services, utilities, work, alterations,
repairs or maintenance to be provided by Landlord under the Underlying Lease, and Sublandlord shall in no way be liable to Subtenant
for any failure of Landlord to provide such services, utilities, work, alterations, repairs or maintenance. Notwithstanding the
foregoing, Sublandlord shall use reasonable efforts to promptly enforce, at Subtenant’s sole cost and expense, all of its
rights under the Underlying Lease upon notice from Subtenant of Landlord’s failure to perform its obligations under the Underlying
Lease.


 




    	 	5	 



     


    

 


8.4           Subtenant’s
Obligations. Subtenant hereby agrees to perform all of the obligations applicable to the Subleased Premises imposed on
Sublandlord as Tenant under the Underlying Lease except for the payment of rent and other charges to Landlord and except as expressly
provided for herein.


 


Subtenant agrees to
indemnify and hold Sublandlord harmless from and against any and all claims, suits, damages, liabilities and expenses, including
reasonable attorneys’ fees, arising out of Subtenant’s use and occupancy of the Subleased Premises.


 


8.5           Violation
of Underlying Lease. Subtenant covenants that it will not commit, or suffer to be committed, any act or act of omission
in violation of the terms and provisions of the Underlying Lease so as to render Sublandlord in default in any of the terms, covenants
and conditions of the Underlying Lease.


 


8.6           Cabling.
Notwithstanding Section 5.10 of the Underlying Lease to the contrary, Subtenant shall be obligated to remove, at Subtenant’s
sole cost and expense, any wiring, cabling and/or other tel/data systems installed by Subtenant within or to otherwise serve the
Subleased Premises pursuant to the terms and provisions of this Sublease, but shall not be obligated to remove any wiring, cabling
and/or other tel/data systems existing within or otherwise serving the Subleased Premises prior to Subtenant’s occupancy
thereof.


 


8.7           Default
by Landlord. In the event of any default by Landlord of the Underlying Lease under the terms thereof, Subtenant shall give
Sublandlord and Landlord written notice thereof, and Sublandlord shall use commercially reasonable efforts to compel Landlord to
cure any such default pursuant to the terms of the Underlying Lease.


 


9.          DEFAULT.


 


9.1           Default
Under Sublease. The occurrence of any of the following shall constitute an “Event of Default”: (a) failure
by Subtenant to pay Base Rent, Additional Rent or any other amounts payable under this Sublease, when due and such failure continues
for more than three (3) business days following written notice from Sublandlord; and (b) failure by Subtenant to observe or perform
any other provision of this Sublease to be observed or performed by Subtenant and such failure continues for more than ten (10)
days following written notice from Sublandlord (provided, however, if such failure is of such a nature that Subtenant cannot reasonably
remedy the same within such ten (10) day period, then Subtenant shall have an additional period, not to exceed thirty (30) days
after the notice described in this subsection (b) to remedy the same, so long as Subtenant promptly commences (and in any event
within such ten (10) day period) and prosecutes such remedy to completion with diligence and continuity). At any time after the
occurrence of an Event of Default, Sublandlord shall have the right to terminate this Sublease by providing written notice to Subtenant
and the effective date of such termination shall be five (5) business days after Subtenant’s receipt of such notice.


 




    	 	6	 



     


    

 


9.2           Underlying
Lease Controls. Except in the Event of Default, which shall be governed by the provisions of Section 9.1 of this Sublease,
(a) whenever a time period is specified in the Underlying Lease within which the Sublandlord, as tenant therein, must give notice
or make a demand following an event, or within which Sublandlord must respond to any notice, request or demand previously given
or made by the Landlord, or comply with any obligation thereunder on such Sublandlord’s part, such time period is hereby
changed (for purposes of this Sublease only) by subtracting five (5) days therefrom, and (b) whenever a time period is specified
in the Underlying Lease within which the Landlord must give notice or make a demand following an event or within which the Landlord
must respond to any notice, request or demand previously given or made by the Sublandlord thereunder, or comply with any obligation
thereunder on Landlord’s part, such time period is hereby changed (for purposes of this Sublease only) by adding five (5)
days thereto. It is the intent of this Section to provide Sublandlord with time within which to transmit to the Landlord any notices
or demands received by Sublandlord from Subtenant, and to transmit to Subtenant any notices or demands received by Sublandlord
from the Landlord.


 


9.3           Remedies.
Sublandlord shall have, in addition and not in limitation of any other remedy permitted by law or by this Sublease, all the rights
and remedies of Landlord under Article VII of the Underlying Lease in the event of a default by Subtenant hereunder.


 


10.         GENERAL
PROVISIONS.


 


10.1         Insurance.
Any insurance required to be carried by Subtenant pursuant to the provisions of the Underlying Lease (including, but not limited
to, Section 5.5.2 of the Underlying Lease) shall name Landlord as well as Sublandlord as additional insured parties.


 


Except to the extent
that the following is prohibited by the terms of any insurance policy carried by either party with respect to the Subleased Premises
or occurrences thereon, each party, on behalf of themselves and their insurers, hereby waives any rights of recovery against the
other (and, in the case of Subtenant, also against Landlord) for loss or injury against which such party is protected by insurance
to the extent of the coverage provided by such insurance.


 


10.2         Holding
Over. If Subtenant occupies (or claims the right to occupy) the Subleased Premises or any portion of the Subleased Premises
after the expiration or earlier termination of this Sublease without having entered into a new sublease of the Subleased Premises
with Sublandlord, Subtenant shall be a tenant-at-sufferance only, shall be subject to all of the terms and provisions of this Sublease,
and shall pay, as use and occupation each month, an amount equal to one hundred fifty percent (150%) of the monthly Base Rent payments
and one hundred percent (100%) of the Additional Rent payments in effect for the last full calendar month preceding the date of
expiration or earlier termination of this Sublease. Such a holding over, even if with the consent of Sublandlord, shall not constitute
a tenancy at will or an extension or renewal of this Sublease, and shall not diminish or affect Sublandlord’s right to recover
possession of the Subleased Premises by self help, re-entry by summary proceedings or otherwise, the provisions of this Sublease,
judicial process or otherwise. Subtenant shall save Sublandlord harmless and will exonerate, defend, indemnify and hold harmless
Sublandlord from and against any and all damages and expenses that Sublandlord suffers on account of Subtenant’s holding
over in the Subleased Premises after the expiration or sooner termination of the term of this Sublease.

10.3         Alterations.
Subtenant shall make no decorations, alterations, additions or improvements to the Subleased Premises without the consent of both
the Landlord and Sublandlord, which consent Sublandlord and Landlord may withhold in their sole discretion. Any and all alterations,
improvements or additions by Subtenant shall be made in compliance with all applicable statutes, laws, ordinances and the like
and shall become the property of Landlord, except to the extent such alterations or improvements constitute trade fixtures of Subtenant.
Subtenant shall indemnify and hold harmless the Landlord and Sublandlord from and against all losses, damages, expenses (including
reasonable attorneys’ fees) and all statutory liens or claims or liens of any contractor, subcontractor, materialman, laborer
or any other party which may arise in connection with any alteration, addition, additional improvement or building to the Subleased
Premises made by Subtenant or Subtenant’s contractors. In the event Subtenant shall make any improvements or alterations
in the Subleased Premises and Landlord shall require the removal thereof, Subtenant shall remove the same and repair all damage
caused thereby prior to the expiration of the term of this Sublease.


 


10.4         Furniture,
Fixtures and Equipment. Subtenant shall have the right to use and maintain all of the furniture, furniture systems and
fixtures located in the Subleased Premises during the Term of the Sublease set forth on Exhibit B attached hereto (collectively,
the “Personal Property”). Subtenant shall not have the right to convey, barter or dispose of any of the Personal Property
and shall maintain the same in good condition and repair throughout the Term, reasonable wear and tear and damage by casualty or
condemnation excepted.


 


10.5         Signage.
Any and all signage shall comply with the Underlying Lease. All costs and expenses associated with removing Subtenant’s signage,
installing new signage for Subtenant or removing signage of Subtenant at the end of the Term shall be paid by the Subtenant.


 


11.         NOTICES.

FIRST
AMENDMENT TO LEASE

XYENTERPRISE INC.


 


First Amendment to
Lease (“First Amendment”) dated as of March 17, 2014 between 101 EDGEWATER LLC, a Delaware limited liability
company (“Landlord”), and XYENTERPRISE INC., a Delaware corporation (“Tenant”).


 


Background


 


Reference is made to
a lease dated April 30, 2012 (the “Lease”) between Landlord and Tenant for certain premises containing 18,763
square feet of Rentable Floor Area (the “Existing Premises”) in the building known as 201 Edgewater Drive, Wakefield,
Massachusetts (the “Building”). Capitalized terms used and not otherwise defined in this First Amendment shall
have the meanings ascribed to them in the Lease.


 


Landlord and Tenant
desire to enter into this First Amendment to add certain expansion space to the Existing Premises on the terms more particularly
set forth in this First Amendment.


 


Agreement


 


FOR VALUE RECEIVED,
Landlord and Tenant agree as follows:


 


1.          Expansion.
Effective as of the Expansion Commencement Date (defined below), Landlord hereby agrees to lease to Tenant and Tenant hereby agrees
to lease from Landlord 5,362 square feet of Rentable Floor Area (the “Additional Premises” the Existing Promises
and the Additional Premises are collectively, referred to as the “Premises” or the “Expanded Premises”)
as shown on the floor plan attached hereto as Exhibit A. Tenant’s lease of the Additional Premises shall be on all
of the same terms and conditions as the Existing Premises, except as otherwise specified herein. Effective as of the Expansion
Commencement Date, the Additional Premises shall be made a part of the Premises under the Lease and Tenant shall be leasing a total
of 24,125 square feet of Rentable Floor Area in the Building. Landlord may elect to send Tenant documentation setting forth the
Expansion Commencement Date and other matters in the form attached as Exhibit D (a “Confirmation of Expansion Commencement”),
which shall be binding subject to Tenant’s right to deliver to Landlord a written notice specifying Tenant’s objections
within ten (10) days of Tenant’s receipt of the Confirmation of Expansion Commencement. The foregoing shall not relieve Landlord
of the obligation to complete punch list items of Landlord’s Initial Construction. Landlord and Tenant acknowledge that the
Initial Term applicable to the Expanded Premises is scheduled to expire on June 30, 2019 (subject to extension pursuant to the
Lease, the “Term Expiration Date”).


 


(a)          Annual
Fixed Rent for the Additional Premises. Subject to the abatement of monthly installments of Annual Fixed Rent for the Additional
Premises described below, commencing on (x) the earlier of (i) the date Tenant enters into possession of all or any portion of
the Additional Premises for the conduct of its business (which shall not be deemed to occur by virtue of the installation or testing
of computers or other equipment or the installation of other property of Tenant in the Additional Premises) or (ii) the Substantial
Completion Date, as such term is defined in the attached Exhibit B (the earlier of such dates being referred to herein as the “Expansion
Commencement Date”) and continuing through (y) the last day of the Term, Tenant shall pay Annual Fixed Rent for the Additional
Premises in the amount per rentable square foot in accordance with the following schedule:


 




     


     


    

 


	Expansion Lease
 Year	 	Rent Per Rentable
 Square Foot	 	 	Annual Fixed Rent	 	 	Monthly
 Installments
 Annual Fixed Rent	 
	1-3	 	$	22,00	 	 	$	117,964.00	 	 	$	9,830,33	 
	4 - Term Expiration Date	 	$	24.00	 	 	$	128,688.00	 	 	$	10,724.00	 



 


An “Expansion Lease Year”
shall consist of twelve (12) calendar months beginning with the Expansion Commencement Date (as defined above), except that if
the Expansion Commencement Date is not the first day of a calendar month, then Expansion Lease Year I shall include the partial
month that includes the Expansion Commencement Date in addition to the following twelve (I2) calendar months, and the Annual Fixed
Rent for Expansion Lease Year 1 shall be proportionately increased, Notwithstanding anything to the contrary contained in the Lease
or this First Amendment, provided that no uncured default exists at the time of the abatement, Tenant shall be entitled to an abatement
of monthly installments of Annual Fixed Rent for the Additional Premises for the two (2) month period beginning on the Expansion
Commencement Date (in an amount not to exceed $19,660.66).


 


(b)          Additional
Rent. Commencing on the Expansion Commencement Date and continuing through the Term Expiration Date, payments of Additional
Rent for Landlord’s Operating Expenses and Taxes with respect to the Additional Premises shall be determined and paid at
the times and in the manner set forth in Sections 2.5 and 2.6 of the Lease, except that (i) the Base Operating Expenses
Per Square Foot of Rentable Floor Area figure for the Additional Premises shall be equal to actual Operating Expenses for calendar
year 2014 adjusted to 95% occupancy and (ii) the Base Taxes Per Square Foot of Rentable Floor Area figure for the Additional Premises
shall be equal to actual Taxes for calendar year 2014. From and after the Expansion Commencement Date, Tenant shall pay for all
electricity consumed in the Additional Premises as set forth in Section 2.7 of the Lease and any other additional charges
incurred under the Lease for the Additional Premises other than Additional Rent for Landlord’s Operating Expenses and Taxes.


 


(c)          As-Is.
The Additional Premises are being leased in their “as-is” condition without representation or warranty by Landlord,
and Landlord shall not be required to perform any work in connection with Tenant’s occupancy of the Additional Premises during
the Term. Notwithstanding the foregoing, Landlord, at Tenant’s cost, subject to the Improvement Allowance set forth in Exhibit
B attached to this First Amendment, shall perform the construction of the initial improvements to the Additional Premises for
Tenant’s occupancy shown on Landlord’s Plans attached hereto as Exhibit B-1, in accordance with the provisions of Exhibit
B to this First Amendment, using Building standard materials and finishes. Any additional improvement to the Additional Premises
not shown on Landlord’s Plans that is requested by Tenant and approved by Landlord shall be constructed at Tenant’s
sole cost and expense, subject to all terms and provisions of the Lease.


 




     


     


    

 


2.          Right
of First Offer. Prior to Landlord’s leasing any available space in the Building (the “First Offer Space”),
to any third party, Landlord shall offer to lease such space (the “Offered Space”) to Tenant at the Expansion
Market Rent (defined below) and except as otherwise specified herein on the same terms and conditions as the Lease, provided however,
that (a) if there are less than three (3) Lease Years left in the Term at the time Landlord is offering to lease the Offered Space,
Tenant may lease the Offered Space only if Tenant has, and irrevocably exercises, an Extension Option set forth in Section 2.4.1
of the Lease for the entire Premises (as expanded by this First Amendment) so that the Offered Space shall be leased by Tenant
for not less than a three (3) year term, (b) the Offered Space shall be leased by Tenant in its “as is” condition,
and (c) the figures for Base Operating Expenses and Base Taxes applicable to the Offered Space shall be the actual amounts for
the calendar year and fiscal year, respectively, in which the Offered Space is to be delivered to Tenant, Any tenant or occupant
of the Offered Space from time to time, any affiliate thereof, or any party having a right (including right of first offer) to
lease such space as of the date hereof shall not be considered a “third-party” for purposes of this Section 2,
and Landlord shall be free to lease the Offered Space to any of the foregoing without offering the same to Tenant.


 


Any offer by Landlord
under this Section 2 may be accepted by Tenant by written notice given within ten (10) days of delivery of Landlord’s
offer. If Tenant does not timely accept Landlord’s offer, then Tenant’s rights under this Section 2 shall be
deemed conclusively waived by Tenant with respect to the next lease of the Offered Space, and Landlord shall have no further obligation
to offer the Offered Space to Tenant before next leasing the same to a third party, but this Section 2 shall apply to any
other lease of First Offer Space. In the event that Tenant accepts any offer by Landlord under this section, the leasing of such
Offered Space and the rent therefor shall be documented by an Amendment to the Lease. Tenant’s rights under this Section
2 shall be rendered void, at Landlord’s election, if Tenant is in default (subject to any applicable notice and cure
periods set forth in the Lease) at the time Landlord offers any space to a third party or at the time Tenant’s lease of any
Offered Space under this Section 2, would otherwise commence.


 


“Expansion
Market Rent” shall mean the then prevailing market rate for a five (5) year lease of office space in the greater Boston,
Massachusetts “Metro-North” area, comparable to the Offered Space in terms of location within a building, finish, age,
building quality and amenities for a tenant of equal size and financial strength as Tenant, under terms and conditions substantially
the same as those on which Tenant shall have the right to lease the Offered Space and taking into account market tenant concessions
in such comparable leases such as tenant improvement allowances and free rent, if any. If Landlord and Tenant have not agreed,
in writing, on the Expansion Market Rent for the Offered Space within fourteen (14) days after Tenant accepts Landlord’s
offer, then at the request of either party Expansion Market Rent for the Offered Space shall be determined in accordance with the
arbitration procedure set forth in Section 2.4.1 of the Lease for the determination of Fair Market Rent.


 


If Tenant exercises
its rights under this Section 2, Landlord shall use reasonable efforts to deliver the Offered Space as set forth in Landlord’s
offer. Landlord’s failure to deliver, or delay in delivering, all or any part of the Offered Space by reason of Force Majeure,
as such term is defined in the Lease, and including continued occupancy of any such Offered Space by any occupant thereof shall
not give rise to any liability of Landlord, shall not alter Tenant’s obligation to accept such Offered Space, when delivered,
shall not constitute a default of Landlord, and shall not affect the validity of the Lease; provided that if delivery of the Offered
Space does not occur within ninety (90) days after the delivery date set forth in Landlord’s Offer, Tenant may elect to withdraw
its exercise of its rights under this Section 2 by notice given within five (5) Business Days after the expiration of such
ninety (90) day period. If Tenant so notifies Landlord, Tenant’s Right of First Offer under this Section 2 shall not
apply to the next lease of the Offered Space in question (but shall apply to subsequent leases thereafter).


 




     


     


    

 


This Section 2
shall not be construed to grant to Tenant any rights or interest in any space in the Building and any claims by Tenant alleging
a failure of Landlord to comply herewith shall be limited to claims for monetary damages and Tenant may not assert any rights in
any space nor file any lis pendens or similar notice with respect thereto.


 


Tenant’s rights
under this Section 2 are personal to Tenant and shall not apply to any Transferee of Tenant (other than a Transferee under
a Permitted Transfer). If at any time during the Term Tenant has Transferred all or any portion of the Premises (not including
Permitted Transfers), then Tenant’s rights under this Section 2 shall be null and void and of no further force or
effect.


 


3.          Termination
of Options. Except (a) as specifically set forth in this First Amendment and (b) for the Extension Option set forth in Section
2.4.1 of the Lease, all other Options set forth in the Lease are hereby terminated. For purposes hereof, “Options”
shall mean (a) all rights or options of Tenant to (i) extend or renew the Lease Term, (ii) expand or contract the Premises or (iii)
relocate within the Building or the Edgewater Office Park; and (b) rights of first refusal or first offer or notice (or similar
rights) with respect to the lease of other space in the Building or the Edgewater Office Park or the purchase of any portion of
the Building or the Edgewater Office Park.


 


4.          Brokerage.
Each of Landlord and Tenant represents and warrants to the other that it has had no dealings with any broker or agent in connection
with this First Amendment, except Cassidy Turley and Wyman Street Advisors, Each; of Landlord and Tenant covenants to the other
to defend (by counsel of reasonably acceptable to the other party), pay, hold harmless and indemnify the other from and against
any and all costs, expense or liability for any compensation, commissions, and charges claimed by any broker or agent, with respect
to this First Amendment or the negotiation thereof arising from a breach of the foregoing warranty. Landlord shall pay all commissions
due to Cassidy Turley and Wyman Street Advisors in connection with this First Amendment pursuant to separate written agreements
between Landlord and Cassidy Turley and Wyman Street Advisors.


 


5.          Ratification.
Except as set forth herein, the terms of the Lease are hereby ratified and confirmed. Each party hereby warrants and represents
that, to the best of its knowledge (i) as of the date hereof the parties have complied with all of the terms and conditions of
the Lease, (ii) Tenant has no rights to any credit, claim, cause of action, offset or similar charge against Landlord or the Annual
Fixed Rent existing as of the date hereof, except as specifically set forth in this First Amendment and (iii) without Landlord’s
prior written consent there have been no assignees, sublessees or transferees of the Lease, or any person or firm occupying or

EXHIBIT B


 


Landlord’s Work


 


		1.	Plans and Specifications.



 


(a)          Preparation
of Plans. Landlord has prepared plans (“Landlord’s Plans”) for the construction of certain improvements
in the Additional Premises attached hereto as Exhibit B-1, which Tenant hereby unconditionally approves. Landlord shall perform
Landlord’s Work consistent with Landlord’s Plans using Building standard materials and finishes. Tenant acknowledges
that Landlord’s Work does not include the installation of telecommunications cabling and equipment.


 


(b)          Change
Orders. Landlord’s Plans shall not be changed or modified except as set forth herein. If Tenant requests a change in
Landlord’s Plans, Landlord shall not unreasonably withhold its consent to said change provided that it shall not be deemed
unreasonable for Landlord to withhold consent to any change in Landlord’s Plans that in Landlord’s sole opinion (i)
will cause any delay in the completion of Landlord’s Work (as hereinafter defined), (ii) cause any additional cost or expense
to Landlord, (iii) in any manner affect any structural component of the Building (including, without limitation, exterior walls,
exterior windows, core walls, roofs, or floor slabs), (iv) in any respect be incompatible with the electrical, mechanical, or plumbing
components or systems of the Building, (v) affect in any respect other space in the Building other than the Additional Premises,
including the exterior of the Building, (vi) diminish the value of the Premises for any general purpose office use, or (vii) require
any unusual expense to readapt the Premises for any general purpose office use. With respect to clauses (i) and (ii) above, Landlord
may, but shall not be obligated to, grant its consent provided Tenant agrees to pay for any and all costs associated therewith.


 


		2.	Completion of Landlord’s Work.



 


(a)          Construction
of Additional Premises. Landlord shall exercise reasonable efforts to substantially complete the work specified in Landlord’s
Plans (“Landlord’s Work”) necessary to prepare the Additional Premises for Tenant’s occupancy on
or before May 1, 2014 (the “Estimated Expansion Commencement Date”), subject to Tenant’s Delays (as hereinafter
defined) and Force Majeure, as such term is defined In Section 4.2 of the Lease.


 


(b)          Substantial
Completion. The Additional Premises shall be deemed ready for occupancy on that day (the “Substantial Completion Date”)
on which Landlord’s Work is “Substantially Complete,” defined to mean that Landlord’s Work has been
completed except for minor items of construction, mechanical and electrical adjustment or other work which Landlord is able to
complete after Tenant has occupied the Additional Premises without unreasonably interfering with Tenant’s use thereof, as
evidenced by an architect’s written certification and the issuance of a valid certificate of occupancy (which may be temporary
or permanent) from the City of Wakefield for the Premises or such other permit or approval entitling Tenant to occupy the Additional
Premises for the Permitted Uses.


 




     


     


    

 


		3.	Improvement Allowance.



 


Landlord shall provide
Tenant with an allowance for the costs of preparing the Additional Premises for Tenant’s initial occupancy (including the
costs of Landlord’s Work and architectural and engineering fees) in an amount not to exceed $67,025.00 (the “Improvement
Allowance”), Landlord shall notify Tenant of the total fixed-price construction cost of Landlord’s Work shown on
Landlord’s Plans (the “Base Price”), including mark-ups as determined hereunder, The Base Price shall
hereafter be subject to adjustment for Change Orders (if any). Costs of Building services or facilities (such as electricity, HVAC,
and cleaning) and other additional costs (such as permit fees, infiltration and inflow charges, and inspection costs) actually
required to implement Landlord’s Work and other variable costs to the extent required to be paid by Tenant under the Lease
(such as for review, inspection, and testing) shall thereafter be added to the Base Price (as adjusted for Change Orders). All
costs referred to in this paragraph shall be subject to reimbursement from the Improvement Allowance. In the event that the total
fixed price of Landlord’s Work (as determined hereunder), together with any related costs reasonably estimated by Landlord,
exceeds the Improvement Allowance, Landlord may from time to time require Tenant to pay such excess to Landlord before performing
the remaining Landlord’s Work. Except as set forth below, Tenant shall have no right to, and Landlord shall have no obligation
to fund, any Improvement Allowance not properly requisitioned by Tenant on or before December 31, 2014. Notwithstanding the foregoing
sentence, if Tenant requests by written notice to Landlord any Improvement Allowance unused after the full and final payment of
Landlord’s Work, then such amount(s) may be used to reimburse Tenant for its actual, documented third party costs of furniture,
cabling and other approved Tenant fixtures in the Additional Premises or toward Tenant’s monthly installments of Annual Fixed
Rent beginning on January 1, 2015,


 


		4.	Excess Work.



 


All Landlord’s
Work (including, without limitation, any Change Orders requested by Tenant, the cost of which exceeds the Improvement Allowance
shall be “Excess Work.” Tenant may seek to reduce the cost of Landlord’s Work by Change Order under Section
1(b), above). All Excess Work shall be performed by Landlord at the sole expense of Tenant.


 


		5.	Tenant’s Delay.



 


(a)          Any
delay that shall occur in the Substantial Completion Date as the result of the following shall be a Tenant’s Delay: any request
by Tenant that Landlord delay in the commencement or completion of Landlord’s Work for any reason;


 


(i)          any
change made or requested by Tenant in any of Landlord’s Plans


 


(ii)         any
special requirements of Tenant not in conformity with Landlord’s Plans;


 


(iii)        any
other act or omission of Tenant or its members, managers, officers, directors, agents, servants, contractors, architects, engineers,
or employees; or


 


(iv)        any
reasonably necessary rescheduling of the sequence of any of Landlord’s Work due to any of the causes for delay referred to
In clauses (i), (ii), (iii), and (iv) of this paragraph (a) of Section 5.


 


(b)          If
any delay in the Substantial Completion Date is the result of Force Majeure and such delay would not have occurred but for any
of Tenant’s Delays described in paragraph (a) of this Section 5, such delay shall be deemed added to Tenant’s
Delays described in that paragraph.


 




     


     


    

 


(c)          In
addition to Landlord’s other rights and remedies under prevailing circumstances, the Expansion Commencement Date shall automatically
be extended for the period of any delays caused by Tenant’s Delay(s) or Force Majeure but the number of days of rent abatement
for the Additional Premises to which Tenant is entitled under Section 1(a) of this First Amendment shall be reduced by the
number of days the Expansion Commencement Date is delayed as a result of a Tenant’s Delay or Force Majeure and Tenant shall
be obligated to commence the payment of Rent on the date Tenant would have commenced payment of Rent but for the Tenant Delay(s)
or Force Majeure.


 


(d)          If,
as a result of Tenant’s Delay(s), the Substantial Completion Date is delayed in the aggregate for more than sixty (60) days,
Landlord may (but shall not be required to) at any time thereafter terminate the First Amendment by giving written notice of such
termination to Tenant, and thereupon the First Amendment shall forthwith terminate without further liability or obligation on the
part of either party, except that Tenant shall pay to Landlord the damages suffered by Landlord by reason of such Lease termination
including, without limitation, the cost theretofore incurred by Landlord in performing and, if applicable, demolishing Landlord’s
Work, plus an amount equal to Landlord’s out-of-pocket expenses incurred in connection with the First Amendment, including,
without limitation, brokerage and legal fees, together with any amount required to be paid pursuant to paragraph (a) of this Section
5, through the effective termination date.


 


		6.	Conclusiveness of Landlord’s Performance.



 


Tenant shall have no
claim that Landlord has failed to perform any of Landlord’s Work, unless Tenant shall have given Landlord notice, not later
than sixty (60) days following the Substantial Completion Date, or, in the case of latent defects, not later than the earlier of
(a) eleven (11) months following the Substantial Completion Date and (b) the date Tenant knew or should have known about such latent
defect, of respects in which Landlord has not performed Landlord’s Work, Except for Landlord’s Work, the Additional
Premises are being leased in their condition “as is” without representation or warranty by Landlord.


 


		7.	Entry Prior to the Expansion Commencement Date.



 


If and as long as Tenant
does not interfere in any, way with the construction process (by causing disharmony, scheduling or coordination difficulties, etc.),
Tenant may, pursuant to the provisions of Section 3.2 of the Lease and at Tenant’s sole risk and expense, enter the
Additional Premises up to thirty (30) days prior to the Substantial Completion Date for the purpose of installing Tenant’s
decorations, movable furnishings, cabling, wiring and business fixtures and equipment. The determination of any such interference
by Landlord shall be conclusive. Prior to Tenant’s occupancy of the Additional Premises, and after Tenant’s written
request to Landlord, Tenant may conduct a walk-through of the Additional Premises accompanied by a representative of Landlord.


 


Prior to the Expansion
Commencement Date Tenant shall comply with and perform, and shall cause its employees, agents, contractors, subcontractors, material
suppliers and laborers to comply with and perform, all Tenant’s obligations under the Lease except the obligations to pay
Annual Fixed Rent and Additional Rent and other obligations, the performance of which would be clearly incompatible with the installation
of decorations, movable furnishings, cabling, wiring and business fixtures and equipment pursuant hereto.


 




     


     


    

 


		8.	Tenant Contractors.



 


Any independent contractor
of Tenant (or any employee or agent of Tenant) performing any work in the Premises or the Additional Premises prior to the Expansion
Commencement Date if and to the extent permitted by Landlord pursuant to the provisions of Section 3.2 of the Lease shall
be a “Tenant Contractor” and shall be subject to all of the terms, conditions and requirements contained in
the Lease. Neither Tenant nor any Tenant Contractor shall interfere in any way with construction of, nor damage, Landlord’s
Work, and shall do all things reasonably requested by Landlord to expedite construction of Landlord’s Work, Without limitation,
Tenant shall require each Tenant Contractor to adjust and coordinate any work or installation in or to the Premises to meet the
schedule or requirements of other work being performed by or for Landlord throughout the Building, which shall in all cases have
precedence. If Tenant or any Tenant Contractor fails so to adjust to the schedule or requirements of Landlord, then Landlord may
immediately by notice to Tenant terminate permission previously granted to Tenant to enter the Additional Premises prior to the
Expansion Commencement Date. Neither Tenant nor any Tenant Contractor shall cause any labor disharmony, and Tenant shall be responsible
for all costs required to produce labor harmony in connection with an entry under this Section. In all events, Tenant shall indemnify
the Indemnitees in the manner provided in Section 5.5.1 of the Lease against any claim, loss or cost arising out of any
interference with, or damage to, Landlord’s Work or any other work in the Building, or any delay thereto, or any increase
in the cost thereof on account in whole or in part of any act, omission, neglect or default by Tenant or any Tenant Contractor.
Without limiting the generality of the foregoing, to the extent that the commencement or performance of Landlord’s Work is
delayed on account in whole or in part of any act, omission, neglect, or default by Tenant or any Tenant Contractor, then such
delay shall constitute a Tenant Delay as provided herein.


 


Any requirements of
any such Tenant Contractor for services from Landlord or Landlord’s contractor, such as hoisting, electrical or mechanical
needs, shall be paid for in advance by Tenant and arranged between such Tenant Contractor and Landlord or Landlord’s contractor,
Should the work of any Tenant Contractor depend on the installed field conditions of any item of Landlord’s Work, such Tenant
Contractor shall ascertain such field conditions after installation of such item of Landlord’s Work. Neither Landlord nor
Landlord’s contractor shall ever be required or obliged to alter the method, time or manner for performing Landlord’s
Work or work elsewhere in the Building, on account of the work of any such Tenant Contractor. Should Landlord’s contractor,
including subcontractors working under such contractor, damage or delay the work of any Tenant Contractor, then such Tenant Contractor,
by entering on the Premises and/or the Additional Premises, shall be deemed to have agreed not to prosecute any claim against Landlord,
but shall look solely to Landlord’s contractor (or such contractor’s subcontractors) that allegedly caused the damage
or delay. If any such Tenant Contractor ever makes a claim against any Indemnitee (as such term is defined in Section 5.5.1
of the Lease) directly, then Tenant shall indemnify such Indemnitee in the manner provided in the Lease against such claim so long
as such Tenant Contractor’s loss was not caused solely and directly by the gross negligence or willful and wrongful act of
such Indemnitee. Tenant shall cause each Tenant Contractor performing work on the Premises or the Additional Premises to clean
up regularly and remove its debris from the Premises, the Additional Premises and Building. If any Tenant Contractor fails so to
clean up, then Landlord may cause its contractor to clean up and remove debris, and Tenant shall pay all costs (including administrative
costs) of such cleanup and removal.

This Lease is subject
to all easements, restrictions, agreements, and encumbrances of record to the extent in force and applicable. Landlord represents
that such title matters shall not affect any of Tenant’s rights under this Lease in any material and adverse respect.


 


2.1.1           RIGHT
OF FIRST OFFER FOR CONTIGUOUS SPACE


 


Prior to leasing certain
premises, of approximately 5,300 square feet of Rentable Floor Area, as shown on Exhibit A-1 (the “First Offer
Space”), to any third party, Landlord shall offer to lease such space (the “Offered Space”) to Tenant at
the Expansion Market Rent (defined below) and except as otherwise specified herein on the same terms and conditions as this Lease,
provided however, that (a) if there are less than three (3) Lease Years left in the Term at the time Landlord is offering to lease
the Offered Space, Tenant may lease the Offered Space only if Tenant has, and irrevocably exercises, an Extension Option set forth
in Section 2.4.1 for the Premises so that the Offered Space shall be leased by Tenant for more than a three (3) year term,
(b) the Offered Space shall be leased by Tenant in its “as is” condition, and (c) the figures for Base Operating Expenses
and Base Taxes applicable to the Offered Space shall be the actual amounts for the calendar year in which the Offered Space is
to be delivered to Tenant. Any tenant or occupant of the Offered Space from time to time, any affiliate thereof (but not if Landlord
would enter into a new lease with such affiliate for such space), or any party having a right (including right of first offer)
to lease such space as of the date hereof shall not be considered a “third-party” for purposes of this Section 2.1.1,
and Landlord shall be free to lease the Offered Space to any of the foregoing without offering the same to Tenant.


 


Any offer by Landlord
under this Section 2.1.1 may be accepted by Tenant by written notice given within ten (10) days of delivery of Landlord’s
offer. If Tenant does not timely accept Landlord’s offer, then Tenant’s rights under this Section 2.1.1 shall
be deemed conclusively waived by Tenant with respect to the next lease of the Offered Space, and Landlord shall have no further
obligation to offer the Offered Space to Tenant before next leasing the same to a third party, but this Section 2.1.1 shall
apply to any other lease of First Offer Space. In the event that Tenant accepts any offer by Landlord under this section, the leasing
of such Offered Space and the rent therefor shall be documented by an Amendment to this Lease. Tenant’s rights under this
Section 2.1.1 shall be rendered void, at Landlord’s election, if Tenant is in default (subject to any applicable notice
and cure periods set forth in this Lease) at the time Landlord offers any space to a third party or at the time Tenant’s
lease of any Offered Space under this Section 2.1.1 would otherwise commence. For the avoidance of doubt, Tenant’s
default will only render the right of first offer void for such specific offer of Offered Space and not for the remainder of the
Term, provided that Landlord has accepted Tenant’s cure of such default.


 


“Expansion
Market Rent” shall mean the then prevailing market rate for a five (5) year lease of office space in the greater Boston,
Massachusetts “Metro-North” area comparable to the Offered Space in terms of location within a building, finish, age,
building quality and amenities for a tenant of equal size and financial strength as Tenant, under terms and conditions substantially
the same as those on which Tenant shall have the right to lease the Offered Space and considering all relevant factors (the parties
intending and agreeing that uncommon or unusual features of other leases in the marketplace will not be considered). If Landlord
and Tenant have not agreed, in writing, on the Expansion Market Rent for the Offered Space within fourteen (14) days after Tenant
accepts Landlord’s offer, then at the request of either party Expansion Market Rent for the Offered Space shall be determined
in accordance with the arbitration procedure set forth in Section 2.4.1 for the determination of Fair Market Rent.


 




    	 	-4-	 



     


    

 


If Tenant exercises
its rights under this Section 2.1.1, Landlord shall use reasonable efforts to deliver the Offered Space as set forth in
Landlord’s offer. Landlord’s failure to deliver, or delay in delivering, all or any part of the Offered Space by reason
of Force Majeure, as such term is defined in Section 4.2, and including continued occupancy of any such Offered Space by
any occupant thereof shall not give rise to any liability of Landlord, shall not alter Tenant’s obligation to accept such
Offered Space when delivered, shall not constitute a default of Landlord, and shall not affect the validity of the Lease; provided
that if delivery of the Offered Space does not occur within ninety (90) days after the delivery date set forth in Landlord’s
Offer, Tenant may elect to withdraw its exercise of its rights under this Section 2.1.1 by notice given within five (5)
Business Days after the expiration of such ninety (90) day period. If Tenant so notifies Landlord, Tenant’s Right of First
Offer under this Section 2.1.1 shall not apply to the next lease of the Offered Space in question (but shall apply to subsequent
leases thereafter).


 


This Section 2.1.1
shall not be construed to grant to Tenant any rights or interest in any space in the Building and any claims by Tenant alleging
a failure of Landlord to comply herewith shall be limited to claims for monetary damages and Tenant may not assert any rights in
any space nor file any lis pendens or similar notice with respect thereto.


 


Tenant’s rights
under this Section 2.1.1 are personal to Tenant and shall not apply to any Transferee of Tenant (other than a Transferee
under a Permitted Transfer). If at any time during the Term Tenant has Transferred all or any portion of the Premises (not including
Permitted Transfers), then Tenant’s rights under this Section 2.1.1 shall be null and void and of no further force
or effect.


 


2.2         APPURTENANT
RIGHTS


 


Tenant shall have,
as appurtenant to the Premises, rights to use in common (subject to reasonable rules of general applicability to tenants and other
users of the Building from time to time made by Landlord of which Tenant is given written notice): (a) the common lobbies, corridors,
stairways, elevators and loading platform, and the pipes, ducts, conduits, wires and appurtenant meters and equipment serving the
Premises in common with others; (b) common driveways and walkways necessary for access to the Building; (c) if the Premises include
less than the entire rentable floor area of any floor, the common toilets, corridors and elevator lobby on such floor and serving
the Premises; (d) the roof of the Building for telecommunications antennae in accordance with Article XI; and (e) the parking
areas and facilities serving the Building from time to time intended for general use by Tenant, other Building tenants, and visitors,
subject to reasonable rules from time to time made by Landlord of which Tenant is given notice which shall at all times permit
unreserved parking for Tenant (at no additional cost to Tenant) at a ratio of 3.36 spaces per 1,000 square feet of Rentable Floor
Area in the Premises. Nothing contained in the Lease shall prohibit or otherwise restrict Landlord from changing, from time to
time, without notice to Tenant, the location, layout or type of the forgoing common areas and facilities, provided that Landlord
shall not substantially reduce the number of parking spaces available for use of tenants of the Building.

2.3         RESERVATIONS


 


Landlord reserves the
right from time to time, with telephonic notice and without unreasonable (except in emergency) interruption of Tenant’s use:
(a) to install, use, maintain, repair, replace and relocate for service to the Premises and other parts of the Building, or either,
pipes, ducts, conduits, wires and appurtenant fixtures, wherever located in the Premises or the Building and (b) to alter or relocate
any other common facility, including without limitation any lobby and courtyard areas. Installations, replacements and relocations
referred to in clause (a) above shall be located as far as practicable in the central core area of the Building, above ceiling
surfaces, below floor surfaces or within perimeter walls of the Premises. Landlord shall provide Tenant with reasonable prior notice
of any such installation, replacement or relocation and shall use reasonable efforts to schedule the making thereof so as to minimize,
to the extent practicable, the interference with Tenant’s business operations.


 


2.4         TERM


 


(a)          If
the Term Commencement Date is a date certain agreed upon by the parties at the time of execution of this Lease, the Term Commencement
Date shall be as set forth in Section 1.1 and the Term shall begin at 12:01 a.m. on such date and shall end at 12:00 midnight
on the Term Expiration Date set forth in Section 1.1 or on such earlier date pursuant to the provisions of this Lease; otherwise,
the following provisions shall govern.


 


(b)          If
the Term Commencement Date is not a date certain, the Term shall begin at 12:01 a.m. on the earlier to occur of the following (i)
or (ii), which date shall be the “Term Commencement Date,” and shall end at 12:00 midnight on the Term Expiration Date
set forth in Section 1.1 or on such earlier date pursuant to the provisions of this Lease.


 


(i)          The
date Tenant enters into possession of all or any portion of the Premises for the conduct of its business. (The event described
in the prior sentence shall not be deemed to occur by virtue of the installation or testing of computers or other equipment or
the installation of other property of Tenant in the Premises.)


 


(ii)         The
Substantial Completion Date, as such term is defined in the attached Exhibit B. Landlord shall provide Tenant with at least fifteen
(15) Business Days prior oral or written notice of Landlord’s estimate of the Substantial Completion Date.


 


Upon request by Landlord, Tenant shall
execute documentation setting forth the Term Commencement Date and other matters in the form attached as Exhibit D, which shall
be binding upon Landlord and Tenant when executed by both parties.


 


(c)          Subject
to delay caused by Force Majeure, as such term in defined in Section 4.2, or caused by action or inaction of Tenant, Landlord
shall endeavor, in good faith, to have the Premises ready for Tenant’s occupancy on the Estimated Term Commencement Date.
Landlord’s failure to have the Premises ready for Tenant’s occupancy on the Estimated Term Commencement Date, for any
reason, shall not give rise to any liability of Landlord hereunder, shall not constitute a Landlord’s default, shall not
affect the validity of this Lease, and shall have no effect on the beginning or end of the Term as otherwise determined hereunder
or on Tenant’s obligations associated therewith.


 




    	 	-6-	 



     


    

 


2.4.2           EXTENSION
OPTION. Tenant shall have the option to extend the Term for one (1) additional five (5) year extension term (the “Extension
Term”) by notice given to Landlord at least nine (9) months before the Term Expiration Date. Tenant’s election
shall be exercised, and Annual Fixed Rent for the Extension Term determined, as set forth below. If Tenant fails timely to exercise
its option for the Extension Term, Tenant shall have no further extension rights hereunder.


 


Tenant’s option
so to extend the Term shall be void, at Landlord’s election, if Tenant is in default (subject to any applicable notice and
cure periods set forth in this Lease) at the time Tenant elects to extend the Term or at the time the Term would expire but for
such extension. The extension of the Term shall be applicable to the entire Premises and Tenant shall have no right to extend the
Term for only a portion of the Premises. During the Extension Term, if any, all provisions of this Lease shall apply except that
Tenant shall have no further option to extend the Term after the Extension Term.


 


During the Extension
Term, Tenant shall pay Annual Fixed Rent equal to ninety-five percent (95%) of the then prevailing market rate for a five (5) year
lease of office space in the greater Boston, Massachusetts “Metro-North” area comparable to the Premises in terms of
location within a building, finish, age, building quality and amenities for a tenant of equal size and financial strength as Tenant,
under terms and conditions substantially the same as those of this Lease as though then available for single occupancy for the
Permitted Uses (or any higher and better use then being made by Tenant) in “as-is” condition or such better condition
in which Tenant is required to maintain the Premises and considering all relevant factors (the parties intending and agreeing that
uncommon or unusual features of other leases in the marketplace will not be considered) (the “Fair Market Rent”).


 


Landlord shall notify
Tenant of its estimate of the Fair Market Rent within ten (10) days after Tenant exercises the extension option. Tenant shall have
the option to reject by written notice Landlord’s estimate, or to withdraw its exercise of the extension option, in any case
within fourteen (14) days following delivery of Landlord’s estimate. Failure to respond within such period shall be deemed
to constitute acceptance of Landlord’s estimate. In the event Tenant rejects Landlord’s estimate then the Fair Market
Rent shall be arbitrated in accordance with the following procedure. In the event Landlord fails to notify Tenant of its estimate
as provided above, the parties shall determine Fair Market Rent by arbitration as set forth below.


 


Each of Landlord and
Tenant, within twenty (20) days after notice by Tenant disputing Landlord’s estimate of the Fair Market Rent, shall (i) submit
to the other in a sealed envelope its final estimate of the Fair Market Rent (“Estimates”) and (ii) appoint an MAI
appraiser with at least ten (10) years experience as an appraiser of office buildings in the Greater Boston “Metro North”
area, including first class suburban office buildings, and shall give notice of such appointment to the other party. If either
Landlord or Tenant shall fail timely to appoint an appraiser, then the appraiser appointed by the other party shall be the sole
appraiser for the purposes hereof. The two appraisers shall, within five (5) Business Days after appointment of the second appraiser,
appoint a third appraiser who shall be similarly qualified. If the two appraisers are unable to agree timely on the selection of
the third appraiser, then either appraiser on behalf of both may request such appointment from the President of the local chapter
of the Appraisal Institute (or its successor organization, or if no successor exists, the most similar organization reasonably
selected by Landlord). The appraisers shall be charged to reach a majority written decision in accordance with the standards for
the Fair Market Rent as provided in this Section 2.4.1, within twenty (20) days after the third appraiser is appointed,
by selecting either of the final Estimates of the Fair Market Rent provided by Landlord and Tenant at the commencement of the hearing.
The appraisers shall have no authority or jurisdiction to make any other determination of such amount. The cost of the third appraiser
shall be borne equally by the parties and otherwise the parties shall bear their own costs.


 




    	 	-7-	 



     


    

 


If Landlord should
delay in giving the notice which begins the valuation procedures of this Section 2.4.1, or if the process should otherwise
be delayed for any reason, then such procedures shall nevertheless remain in effect and be applicable when and as invoked with
respect to Annual Fixed Rent payable during the Extension Term; but until such procedures are completed, Tenant shall pay on account
of Annual Fixed Rent at the rate established for Annual Fixed Rent for the last twelve (12) months of the Term (and upon Fair Market
Rent being established, Tenant shall pay the same within ten (10) days of such determination, retroactively to the beginning of
the Extension Term). The parties shall adjust for over or under payments within twenty (20) days after the decision of the appraisers
is announced.


 


Promptly after the
Annual Fixed Rent is determined for the Extension Term, Landlord and Tenant shall enter into an amendment of this Lease confirming
the extension of the Term and the new rate for Annual Fixed Rent.


 


Tenant’s rights
under this Section 2.4.1 are personal to Tenant and shall not apply to any Transferee of Tenant (other than a Transferee
under a Permitted Transfer). If at any time during the Term Tenant has Transferred more than 4,000 rentable square feet of the
Premises (not including Permitted Transfers), then Tenant’s rights under this Section 2.4.1 shall be null and void
and of no further force or effect.


 


2.5         ANNUAL
FIXED RENT


 


Tenant covenants and
agrees to pay the Annual Fixed Rent in Section 1.1 to Landlord in advance in equal monthly installments commencing on the
Term Commencement Date (if not the first day of a month) and thereafter on the first day of each calendar month during the Term.
All payments shall be due without billing or demand and without deduction, setoff or counterclaim, except as expressly set forth
in this Lease. Tenant shall make payment for any portion of a month at the beginning or end of the Term. All payments shall be
payable to Landlord at Landlord’s address, as specified in Section 1.1, or to such other entities at such other places
as Landlord may from time to time designate.


 


Without limiting the
foregoing, except as expressly set forth in this Lease, Tenant’s obligation so to pay Rent (as hereinafter defined) shall
not be discharged or otherwise affected by any law or regulation now or hereafter applicable to the Premises, or any other restriction
on Tenant’s use, or any casualty or taking, or any failure by Landlord to perform any covenant contained herein, or any other
occurrence; and, except as expressly set forth in this Lease, Tenant waives all rights now or hereafter existing to terminate or
cancel this Lease or quit or surrender the Premises or any part thereof, or to assert any defense in the nature of constructive
eviction to any action seeking to recover Rent.


 




    	 	-8-	 



     


    

 


The foregoing notwithstanding,
if Landlord fails for any reason within Landlord’s control to provide any service to be supplied by Landlord under the Lease
which is necessary for Tenant’s reasonable use of the Premises (such as HVAC, elevator service, electricity, water, or structural
repairs), and Tenant is unable to use the Premises on account of such failure, Tenant shall be entitled to a proportional abatement
of Annual Fixed Rent and Additional Charges for Operating Expenses and Taxes based on the portion of the Premises which cannot
be used by Tenant. This abatement shall begin on the fourth (4th) consecutive Business Day from Tenant’s written notice to
Landlord of the failure. The abatement shall end when the services are restored sufficiently to permit use of the Premises.


 


2.6         ADDITIONAL
RENT - OPERATING EXPENSES AND TAXES


 


2.6.1           ADDITIONAL
RENT - GENERAL COVENANT. Tenant covenants and agrees to pay to Landlord, as “Additional Rent”, (i)
an amount equal to the product of (a) the Rentable Floor Area of the Premises and (b) the excess (if any) of Landlord’s Operating
Expenses per square foot of Rentable Floor Area of the Building over Base Operating Expenses per Square Foot of Rentable Floor
Area of the Building, (ii) an amount equal to the product of (a) the Rentable Floor Area of the Premises and (b) the excess (if
any) of Landlord’s Taxes per square foot of Rentable Floor Area of the Building over Base Taxes Per Square Foot of Rentable
Floor Area of the Building provided that if less than the Total Rentable Floor Area of the Building is occupied at any time during
such period, Landlord may extrapolate components of Landlord’s Operating Expenses and Landlord’s Taxes as though the
Total Rentable Floor Area of the Building had been ninety-five percent (95%) occupied at all times during such period, and (iii)
any other charges payable by Tenant to Landlord under this Lease. The term “Rent” as used in this Lease shall mean
Annual Fixed Rent and Additional Rent as set forth in this Lease. Appropriate adjustments shall be made for any portion of a year
at the beginning or end of the Term.


 


2.6.2           PAYMENT.
Additional Rent for Operating Expenses and Taxes under this Section 2.6 shall be paid for any portion of a month at the
beginning of the Term and thereafter in monthly installments on the first day of each calendar month in amounts reasonably estimated
by Landlord for the then current calendar year, all without deduction, setoff or counterclaim. Landlord may from time to time,
but not more than once per calendar year and upon thirty (30) days prior notice to Tenant, revise such estimates based on available
information relating to Landlord’s Operating Expenses and Taxes or otherwise affecting the calculation hereunder. Landlord
will provide Tenant with an accounting statement of Landlord’s Operating Expenses and Taxes and other data necessary to calculate
Additional Rent hereunder for such calendar year prepared in reasonable “line item” detail, and consistently maintained
from year to year in accordance with generally accepted accounting principles. Landlord shall use reasonable efforts to provide
such statement within ninety (90) days after the end of each calendar year. Any such statement shall be binding upon Tenant unless
disputed in accordance with Section 2.6.5. Upon issuance thereof, there shall be an adjustment between Landlord and Tenant
for the calendar year covered by such accounting to the end that Landlord shall have received the exact amount of Additional Rent
due hereunder. In no event shall Additional Rent for Operating Expenses and Taxes be less than zero. Any overpayments by Tenant
hereunder shall be credited against the next payments of Additional Rent due under this Section 2.6 or upon Tenant’s
written request refunded within ten (10) business days (or if such overpayment applies to the last year of the Term, then such
overpayment shall be paid by Landlord to Tenant within thirty (30) days following the date such overpayment is determined), provided
there are no outstanding amounts due Landlord under this Lease at such time. Any underpayments by Tenant shall be due and payable
within thirty (30) days of delivery of Landlord’s statement. With respect to the calendar year in which the Term ends, the
adjustment shall be pro rated for the portion of the year included in the Term, but shall take place nevertheless at the times
provided in the preceding sentences.

TAXES” - DEFINITION. “Landlord’s Taxes” means all taxes, assessments and similar charges
assessed or imposed on the Land for the then current fiscal year by any governmental authority attributable to the Building and
any associated parking structure (including personal property associated therewith). The amount of any special taxes, special assessments
and agreed or governmentally imposed “in lieu of tax” or similar charges shall be included in Landlord’s Taxes
for any year but shall be limited to the amount of the installment (plus any interest, other than penalty interest, payable thereon)
of such special tax, special assessment or such charge required to be paid during or with respect to the year in question. Landlord’s
Taxes include expenses, including fees of attorneys, appraisers and other consultants, incurred in connection with any efforts
to obtain abatements or reduction or to assure maintenance of Landlord’s Taxes for any year wholly or partially included
in the Term, whether or not successful and whether or not such efforts involved filing of actual abatement applications or initiation
of formal proceedings. Landlord’s Taxes exclude income taxes of general application and all estate, succession, inheritance
and transfer taxes. If at any time during the Term there shall be assessed on Landlord, in addition to or lieu of the whole or
any part of the ad valorem tax on real or personal property, a capital levy or other tax on the gross rents or other measures of
building operations, or a governmental income, franchise, excise or similar tax, assessment, levy, charge or fee measured by or
based, in whole or in part, upon building valuation, gross rents or other measures of building operations or benefits of governmental
services furnished to the Building, then any and all of such taxes, assessments, levies, charges and fees, to the extent so measured
or based, shall be included within the term Landlord’s Taxes, but only to the extent that the same would be payable if the
Building and Land were the only property of Landlord.


 


2.6.5           AUDIT
RIGHTS. At the request of Tenant at any time within ninety (90) days after Landlord delivers Landlord’s statement
of Landlord’s Operating Expenses and Taxes to Tenant, Tenant (at Tenant’s expense) shall have the right to examine
Landlord’s books and records applicable to Landlord’s Operating Expenses and Taxes. Such right to examine the records
shall be exercisable: (a) upon reasonable advance notice to Landlord and at reasonable times during Landlord’s business hours;
(b) only during the 90-day period following Tenant’s receipt of Landlord’s statement of the actual amount of Landlord’s
Operating Expenses and Taxes for the applicable calendar year; and (c) not more than once each calendar year. Notwithstanding anything
herein to the contrary, Tenant shall have no right to examine Landlord’s books and records and audit Landlord’s Operating
Expenses and Taxes if Tenant shall have withheld or otherwise failed to pay any Additional Rent when due. Landlord’s statement
of Operating Expenses and Taxes shall be binding upon Tenant except as to items specifically disputed in writing by notice from
Tenant to Landlord given within 105 days after Landlord delivers the statement to Tenant. Tenant shall pay all costs of the audit
unless Tenant is found to have overpaid Additional Rent for Operating Expenses and Taxes by more than 5% for the year in question.
In any event any audit of Landlord’s Operating Expenses and Taxes shall be conducted by an independent certified public accountant
retained by Tenant or an auditing firm approved by Landlord for such purpose (each, an “examiner”). In no event shall
Tenant propose, nor shall Landlord ever be required to approve, any examiner of Tenant who is being paid on a contingent fee basis
or is representing other tenants in the Building.

As a condition precedent
to performing any such examination of Landlord’s books and records, Tenant and its examiners shall be required to execute
and deliver to Landlord an agreement in form acceptable to Landlord agreeing to keep confidential any information that they discover
about Landlord or the Building in connection with such examination. Without limiting the foregoing, such examiners shall also be
required to agree that they will not represent any other tenant in the Building in connection with examinations of Landlord’s
books and records for the Building unless said tenant(s) have retained said examiners prior to the date of the first examination
of Landlord’s books and records conducted by Tenant pursuant to this Section 2.6.5 and have been continuously represented
by such examiners since that time. Notwithstanding any prior approval of any examiners by Landlord, Landlord shall have the right
to rescind such approval at any time if in Landlord’s reasonable judgment the examiners have breached any confidentiality
undertaking to Landlord or any other landlord or cannot provide acceptable assurances and procedures to maintain confidentiality.


 


2.7         ELECTRICITY


 


Tenant acknowledges
and agrees that there is an electric meter presently located in the Premises which shall be used for the purpose of measuring Tenant’s
use and consumption of electricity in the Premises, and Tenant shall make direct payment to the applicable utility for any costs,
expenses and charges for electricity relating to the Premises as Additional Rent, Tenant shall have the right to contract with
alternate electric service providers and Landlord shall not receive any compensation whatsoever for allowing such access, provided
that Landlord shall not be required to incur any material cost or expense in connection with such service, there shall be no interference
with the operation of the Building or the operations of other tenants, and all work to provide such service shall comply with the
applicable provisions of this Lease.


 


Tenant covenants and
agrees that Landlord shall in no event be liable or responsible to Tenant for any loss, damage or expense which Tenant may sustain
or incur if either the quality or character of electrical service is changed or is no longer suitable for Tenant’s requirements.
Tenant covenants and agrees that at all times its use of electric current shall never exceed the capacity of existing feeders to
the Building or the risers or wiring or installation of the Building. Landlord shall be responsible for the maintenance, repair
and replacement of the electric meter unless the need for such maintenance, repair or replacement is the result of misuse or the
negligence or wrongful acts or omissions of Tenant.

INITIAL CONSTRUCTION. Landlord, at Landlord’s cost, shall perform the construction of the initial improvements

COVENANTS


 


4.1.1           BUILDING
SERVICES. Landlord shall furnish services, utilities, facilities and supplies set forth in this Section 4.1.1
and in Exhibit C. Exhibit C is intended to add detail to the provisions of the main body of the Lease, and in case
of conflict, the provisions of the main body of the Lease shall control. Tenant may obtain additional services, utilities, facilities
and supplies from time to time upon reasonable advance request or Landlord may furnish the same without request if Landlord determines
that Tenant’s use or occupancy of the Premises necessitates the same (for example where the condition of the Premises necessitates
additional cleaning services), and, in either case, the cost of the same at reasonable rates from time to time established by Landlord
shall constitute Additional Rent, payable upon demand. For all purposes in this Lease, the phrase “Hours of Operation”
shall mean Mondays through Fridays excepting legal holidays in the state in which the Building is located from 8:00 a.m. to 6:00
p.m. and on Saturdays from 9:00 a.m. to 1:00 p.m. Notwithstanding the foregoing, Tenant shall have access to the Premises 24 hours

(a)          WATER
CHARGES. Landlord shall furnish hot and cold water for ordinary office cleaning, toilet, lavatory and drinking purposes. If
Tenant requires, uses or consumes water for any other purpose, Landlord may assess Tenant reasonable charges for additional water.


 


(b)          CLEANING.
Landlord shall cause the common areas and the office areas of the Premises to be kept reasonably clean provided the same are maintained
and kept in good order by Tenant. Cleaning standards shall be in accordance with Exhibit C.


 


(c)          HEAT
AND AIR-CONDITIONING. Landlord shall, through the Building heating and air-conditioning system, furnish to and distribute in
the Premises heat during the Hours of Operation of the normal heating season and air conditioning during the Hours of Operation
of the normal cooling season when air conditioning may reasonably be required for the comfortable occupancy of the Premises by
Tenant. Landlord shall not be required to furnish heat and air-conditioning in the Premises in excess of the capacity of the equipment
installed in the Building. If Tenant requests Landlord to provide heat or air conditioning beyond the Hours of Operation, Tenant
shall pay Landlord therefor at rates reasonably established by Landlord from time to time, to reflect Landlord’s actual cost
without mark-up to Tenant. If Tenant requires additional air-conditioning outside of normal Hours of Operation for business machines,
meeting rooms or other purposes, or because of occupancy or unusual electrical loads, any additional air-conditioning units, chillers,
condensers, compressors, ducts, piping and other equipment and facilities will be installed and maintained by Landlord at Tenant’s
sole cost, but only to the extent that the same are compatible with the Building and its mechanical systems. During the Term, Tenant
may use the existing supplemental HVAC unit in the Premises (the “HVAC Unit”). Tenant acknowledges and agrees
that, (i) Landlord shall have no obligation or liability with respect to any such HVAC Unit, (ii) the presence or absence of such
HVAC Unit will not cause any delay in the Term Commencement Date, (iii) Landlord makes no representations or warranties as to the
condition or suitability of such HVAC Unit for Tenant’s use, and (iv) Tenant shall be solely responsible for such HVAC Unit
(including, without limitation, for insurance, safety and maintenance).


 


4.1.2           REPAIRS.
Except as otherwise provided in this Lease, and except for repairs to items referred to below necessitated by Tenant’s act
or neglect (which shall be Tenant’s repair obligation under Section 5.1), Landlord shall make such repairs to the
roofs, exterior walls, exterior windows of the Premises (except if such damage or repair is necessitated by the Tenant’s
negligence or willful misconduct), floor slabs, core walls, and common areas and facilities in the Building as may be necessary
to keep them in good condition.


 


4.1.3           QUIET
ENJOYMENT. Landlord covenants that Tenant, on paying the Rent and performing the tenant obligations in this Lease, shall
peacefully and quietly have, hold and enjoy the Premises, free from any claim by Landlord or persons claiming under Landlord, but
subject to all of the terms and provisions hereof, provisions of law and rights of record to which this Lease is or may become
subordinate. This covenant is in lieu of any other so-called quiet enjoyment covenant, either express or implied.

4.2         INTERRUPTION


 


Except as expressly
set forth in this Lease, Landlord shall not be liable to Tenant for any compensation or reduction of Rent by reason of inconvenience
or annoyance or for loss of business arising from Landlord or its agents entering the Premises for any of the purposes authorized
in this Lease or from repairs by Landlord of any portion of the Building. In case Landlord is prevented or delayed from diligent
construction of improvements, making any repairs, alterations or improvements, or furnishing any services or performing any other
covenant or duty to be performed on Landlord’s part, by reason of strike or other labor trouble, fire or other casualty,
or inability to obtain supplies, or labor despite reasonable efforts, or unusually adverse weather conditions, or unforeseen subsurface
conditions, or acts of God, war, terrorism or other public emergency, or delays due to government regulation or delays in obtaining
insurance proceeds, or any other cause whether similar or dissimilar beyond Landlord’s reasonable control collectively and
individually (“Force Majeure”), Landlord shall not be liable to Tenant therefor, nor, except as otherwise provided
in this Lease, shall Tenant be entitled to any abatement or reduction of Rent by reason thereof, nor shall the same give rise to
a claim in Tenant’s favor that such failure constitutes actual or constructive, total or partial, eviction from the Premises.
In no event shall Landlord be liable for indirect or consequential damages arising out of any default by Landlord.


 


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; provided, however, that in each instance of stoppage, Landlord shall exercise reasonable diligence to eliminate
the cause thereof. 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 interruption of Tenant’s use of the Premises by reason thereof.


 


4.3         INSURANCE


 


4.3.1           PROPERTY
INSURANCE. Landlord agrees to maintain throughout the Term, with companies licensed and approved to write insurance
in the state in which the Building is located, property insurance against direct physical loss or damage to the Building on an
“all risks,” agreed amount basis in an amount equal to the physical replacement cost of the Building. Landlord shall
not be required to carry insurance with respect to any property that Tenant is required to insure pursuant to Section 5.5.

injure, overload, deface or commit waste in the Premises or any part of the improvement on the Land, nor permit the emission therefrom
of any objectionable noise, light or odor, nor use or permit any use of the Premises which is improper, offensive, contrary to
law or ordinance or which is liable to invalidate or increase the premium for any insurance on the Building or its contents or
which is liable to render necessary any alterations or additions in the Building, nor obstruct in any manner any portion of the
Building. If Tenant’s use of the Premises results in an increase in the premium for any insurance on the Building or the
contents thereof (or would result in such an increase if the Landlord were not self-insuring), Landlord shall notify Tenant of
such increase and Tenant shall pay same as Additional Rent.


 


Tenant shall not without
Landlord’s prior written consent keep, store, or use any substances or materials designated as, or containing components
now or hereafter designated as, hazardous, dangerous, toxic or harmful and/or subject to regulation under any federal, state or
local law, regulation or ordinance (“Hazardous Substances”) in, on, under or about the Premises or Building
or Complex except for ordinary cleaning and office supplies used and stored in accordance with applicable law. With respect to

Chapter 21C, and the Massachusetts Oil and Hazardous Material Release Prevention Act, as amended, M.G.L. Chapter 21E, and the regulations
adopted under these acts. In addition, Tenant shall execute affidavits, representations and the like from time to time at Landlord’s
request concerning Tenant’s best knowledge and belief regarding the presence of Hazardous Substances on the Premises.


 




    	 	-16-	 



     


    

 


If any governmental
agency shall ever require testing to ascertain whether or not there has been any release of Hazardous Substances, then the reasonable
costs thereof shall be reimbursed by Tenant to Landlord upon demand as Additional Rent if such requirement is the result of Tenant’s
use or occupancy of the Premises. Any and all costs incurred by Landlord in connection with Landlord’s monitoring of Tenant’s
compliance with this Section 5.2, including Landlord’s attorneys’ fees and costs, shall be Additional Rent and
shall be due and payable to Landlord within ten (10) days of Landlord’s demand. Tenant shall be fully and completely liable
to Landlord (either with or without negligence) for any and all cleanup costs and expenses and any and all other charges, expenses,
fees, fines, penalties (both civil and criminal) and costs imposed with respect to Tenant’s use, disposal, transportation,
generation and/or sale of, or Tenant’s causing or permitting the escape, disposal or release, of any biologically or chemically
active or other Hazardous Substance. In all events, Tenant shall indemnify Landlord as provided in Section 5.5 from any

Tenant shall use the
Premises only as permitted under federal, state, and local laws, regulations and orders applicable from time to time, including
without limitation municipal by-laws, land use and zoning laws, environmental laws and regulations (as set forth in Section
5.2 above) and occupational health and safety laws, and shall procure all approvals, licenses and permits necessary therefor,
in each case giving Landlord true and complete copies of the same and all applications therefor. Tenant shall promptly comply with
all present and future laws applicable to Tenant’s particular use of the Premises or Tenant’s signs thereon, foreseen
or unforeseen, and whether or not the same necessitate structural or other changes or improvements to the Premises or interfere
with its particular use and enjoyment of the Premises, and shall comply with all requirements reasonable in light of the use Tenant
is making of the Premises of insurance inspection or rating bureaus having jurisdiction. If Tenant’s use of the Premises
results in any increase in the premium for any insurance carried by Landlord, then upon Landlord’s notice to Tenant of such
increase Tenant shall pay the same to Landlord within sixty (60) days after demand as Additional Rent. Tenant shall bear the sole
risk of all present or future laws affecting the Premises or appurtenances thereto, and Landlord shall not be liable for (nor suffer
any reduction in any rent on account of) any interruption, impairment or prohibition affecting the Premises or Tenant’s use
thereof resulting from the enforcement of laws.

AND REGULATIONS


 


Tenant shall conform
to all reasonable non-discriminatory rules and regulations now or hereafter promulgated from time to time by Landlord for the care
and use of the Premises and the Building and the parking areas and facilities serving the Building, including but not limited to
rules and regulations relating to the conservation of energy and the initial Rules and Regulations set forth at www.hobbsbrook.com.

5.5         INDEMNIFICATION
AND INSURANCE


 


5.5.1           INDEMNIFICATION.
Tenant shall save Landlord, its mortgagees and its direct and indirect owners, and the managers, directors, officers, trustees,
agents, employees, property management companies, attorneys, and independent contractors of any of the foregoing (collectively,
the “Indemnitees”) harmless and indemnified (and shall defend the Indemnitees with counsel reasonably approved
by the Indemnitees) against any claim, loss or cost, whether in law or equity, and/or arising in whole or in part out of any injury,
loss, theft or damage to any person or property while on, in or about the Premises, or out of any condition within the Premises,
to the extent not due to the negligence or willful misconduct of the Indemnitees, and to any person or property anywhere occasioned
by any act, omission, neglect or default of Tenant or of employees, agents, managers, officers, directors, members, trustees, independent
contractors or invitees of Tenant or any person acting under Tenant. In addition to the foregoing, if any person not a party to
this Lease shall institute any other types of action against Tenant in which Indemnitees involuntarily and/or without cause, shall
be made a party defendant(s), then Tenant shall indemnify, hold harmless and defend indemnitees (with counsel reasonably approved
by Indemnitees) from all liabilities by reason thereof. This indemnity shall not require payment as a condition precedent to recovery.
Tenant shall pay all costs and expenses including reasonable attorneys’ fees associated with enforcement of the provisions
of this Section 5.5.1. Except as may be provided in Section 4.2 and 5.6 and subject to the limitations elsewhere
set forth in this Lease, Landlord will cause Tenant to be indemnified and held harmless from and against third party claims against
Tenant for damage to property or injuries to persons while on or in the common areas of the Building to the extent due to Landlord’s
negligence or willful misconduct. The provisions of this Section 5.5.1 shall survive the expiration or earlier termination
of this Lease.


 


5.5.2           INSURANCE.
Throughout the Term (and such further time as Tenant or any person claiming through Tenant occupies any part of the Premises) Tenant
shall maintain in a responsible company or companies licensed in the state in which the Building is located and having a Best’s
Insurance Rating of not less than A-VIII (or equivalent), Commercial General Liability Insurance for Bodily Injury, Personal Injury
and Property Damage and insurance that includes Products and Completed Operations, Personal and Advertising Injury, Automobile
Liability, and Contractual Liability, written on an occurrence basis, insuring the Indemnitees and other parties as designated
by Landlord or as may be so designated from time to time, and Tenant, as their respective interests may appear, against all claims,
demands or actions for injury, death, and property damage in amounts not less than those specified in Section 1.1 (as such
amounts may, from time to time, be reasonably increased by Landlord) and worker’s compensation insurance as required by applicable
law. Landlord and the other Indemnitees shall be named as additional insureds under such liability insurance policies (excluding
any worker’s compensation policy). Such Commercial General Liability insurance coverage shall be primary and any other insurance
procured for the benefit of such additional insureds will be excess and non-contributory. All insurance to be maintained by Tenant
under this Section 5.5.2 shall provide that it will not be subject to cancellation, termination, or change except after
at least thirty (30) days’ prior written notice to the Indemnitees and other parties designated by Landlord. The policy or
policies or a duly executed Evidence of Insurance (ACORD Form 25) for the same (together with satisfactory evidence of the payment
of the premium thereon if requested by Landlord) shall be deposited with Landlord and other parties designated by Landlord at the
beginning of the Term and, upon renewals of such policies, not less than two (2) Business Days prior to the expiration of the term
of such coverage. If Tenant fails to comply with any of the foregoing requirements, Landlord may obtain such insurance on behalf
of Tenant and may keep the same in effect, and Tenant shall pay Landlord, as Additional Rent, the premium cost thereof upon demand.
The provisions of this Section 5.5.2 shall survive the expiration of the Term or earlier termination of this Lease.

All furnishings, fixtures,
equipment, effects and property of Tenant and of all persons claiming through Tenant which from time to time may be on the Premises
or elsewhere in the Building or in transit thereto or therefrom shall be at the sole risk of Tenant and shall be kept insured by
Tenant throughout the term at Tenant’s expense and in prudent amounts, and if the whole or any part thereof shall be destroyed
or damaged by fire, explosion, water leakage, rupture of water pipes or other Building equipment or facilities, or resulting from
dampness, or by theft or from any other cause whatsoever in the Building, no part of said loss or damage is to be charged to or
be borne by Landlord. The parties acknowledge that damage or destruction may result from acts of cleaning personnel and employees
of other independent contractors of Landlord working in and around the Premises and that Tenant shall bear the risk and cost thereof
unless Landlord has been grossly negligent in the selection of such persons.


 


5.7         ENTRY
FOR REPAIRS ANT) INSPECTIONS


 


Tenant shall permit
Landlord and its agents to enter and examine the Premises at reasonable times, upon reasonable prior oral or written notice (except
in the case of an emergency, in which event no notice shall be required), and, if Landlord shall so elect, to make any repairs
or replacements Landlord may deem necessary or desirable, to remove at Tenant’s expense any alterations, additions, signs
or the like not consented to in writing, and to show the Premises to prospective tenants during the twelve (12) months preceding
the expiration of the Term and to prospective purchasers and mortgagees at all times. In case of an emergency in the Premises or
in the Building, Landlord or its representative may enter the Premises (forcibly, if necessary) at any time to take such measures
as may be needed to deal with such emergency.


 




    	 	-19-	 



     


    

 


5.8         ASSIGNMENT.
SUBLETTING 


 


Tenant, voluntarily
or involuntarily, shall not assign this Lease, or sublet, license, mortgage or otherwise encumber or convey the Premises or any
portion thereof, or permit the occupancy of all or any portion of the Premises other than by the Tenant (all or any of the foregoing
actions are referred to as “Transfers”, and all or any of assignees, transferees, licensees, and other such
parties are referred to as “Transferees”) without obtaining, on each occasion, the prior written consent of
the Landlord, which consent shall not be unreasonably withheld, conditioned or delayed. Any Transfer without such consent shall
be null and void and of no effect whatsoever. Notwithstanding the provisions of this Section 5.8, this Lease may be assigned,
or the Premises may be sublet, in whole or in part, after prior notice to Landlord but without consent of the Landlord and without
any termination right of the Landlord being applicable thereto, (i) to any corporation or other entity into or with which Tenant
may be merged or consolidated or to any corporation or entity to which all or substantially all of the Tenant’s assets will
be transferred, or (ii) to any corporation or other entity which is an affiliate, subsidiary, parent or successor of Tenant, provided
in all such cases the surviving corporation or entity shall provide reasonable evidence that it has a creditworthiness at least
equal to the greater of the net worth of Tenant (i) as of the date of such corporate transaction, and (ii) as of the date of this
Lease and shall agree in writing with the Landlord to be bound by all of the terms and conditions of this Lease (all of the foregoing
being referred to as a (“Permitted Transfer”). Unless Landlord’s consent specifically provides otherwise
with respect to a particular proposed Transferee, Tenant shall not offer to make or enter into negotiations with respect to a Transfer
to any of the following: (i) a tenant in the Building or any other building owned, managed or controlled by Landlord; (ii) any
party with whom Landlord or any affiliate of Landlord is then negotiating with respect to space in the Building or any other building
owned, managed or controlled by Landlord or an affiliate of Landlord; or (iii) any party which would be of such type, character
or condition as to be inappropriate, in Landlord’s reasonable judgment, as a tenant for a first class office building. Tenant’s
request for consent to a Transfer shall include a copy of the proposed Transfer instrument together with a statement of the proposed
Transfer in detail satisfactory to Landlord, together with reasonably detailed financial, business and other information about
the proposed Transferee.


 


Tenant shall pay to
Landlord, as Additional Rent, Landlord’s reasonable legal fees and other expenses incurred in connection with any proposed
Transfer (except a Permitted Transfer), including fees for review of documents and investigations of proposed Transferees. Notwithstanding
any such Transfer, the original Tenant named herein shall remain directly and primarily obligated under this Lease.


 


If Tenant enters into
any Transfer including a Permitted Transfer with respect to the Premises (or any part thereof), such Transferee shall be liable,
jointly and severally, with Tenant, to the extent of the obligation undertaken by or attributable to such Transferee, for the performance
of Tenant’s agreements under this Lease (including payment of Rent under the Transfer), and every Transfer shall so provide,
without relieving or modifying Tenant’s liability hereunder. The foregoing provision shall be self-operative, but in confirmation
thereof, such Transferee shall execute and deliver such instruments as may be reasonably required by Landlord to acknowledge such
liability. Landlord may collect Rent from the Transferee and apply the net amount collected to the Rent and other charges hereunder,
but no such assignment or collection shall be deemed a waiver of the provisions of this Section 5.8, or the acceptance of
the Transferee as a tenant, or a release of Tenant from direct and primary liability for the further performance of Tenant’s
covenants hereunder. The consent by Landlord to a particular Transfer shall not relieve Tenant from the requirement of obtaining
the consent of Landlord to any further Transfer.


 




    	 	-20-	 



     


    

 


5.9         ALTERATIONS


 


Tenant shall make no
alterations, additions or improvements to the Premises (any of the foregoing being “Tenant Work”) without the
prior written consent of Landlord and only in accordance with the requirements of this Lease and Landlord’s rules and regulations
under Section 5.4. Notwithstanding the foregoing, after notice to Landlord but without any requirement for Landlord’s
consent, Tenant may perform (i) cosmetic or decorative alterations in the Premises (including repainting and installing carpet)
and (ii) other alterations which do not affect the Building’s structure or base building systems and which cost no more than
$20,000 in the aggregate for a single project, provided that all such alterations are made in accordance with the requirements
of this Lease, including without limitation this Section 5.9 and Exhibit B. Prior to commencing work, Tenant’s
contractors shall provide certificates of insurance to Landlord evidencing that such contractors have sufficient insurance to complete
the portion of the Tenant Work for which they are responsible, in such form and amounts as may be approved by Landlord in advance.
Any alterations, additions and improvements to the Premises, except movable furniture and trade fixtures, shall belong to Landlord.
All alterations, additions and improvements to the Premises shall be at Tenant’s sole cost. Tenant shall pay, when due, the
entire cost of all Tenant Work so that the Premises shall always be free of liens for labor or materials or professional services
by design professionals. If any mechanic’s lien (which term shall include all similar liens relating to the furnishing of
labor and materials and professional services by design professionals) is filed against the Building which is claimed to be attributable
to Tenant, its agents, employees, contractors, or persons working under Tenant’s direction or control, then Tenant shall
give Landlord immediate notice of such lien and shall discharge the same by payment or filing any necessary bond within ten (10)
days after Tenant has notice (from any source) of such lien. Landlord may, as a condition of its approval of any Tenant Work, require
Tenant to deposit with Landlord a bond, letter of credit or other similar security in the amount of Landlord’s reasonable
estimate of the value of such Tenant Work securing Tenant’s obligations to make payments for such Tenant Work. Landlord’s
approval of the construction documents shall signify Landlord’s consent to the work shown thereon only and Tenant shall be
solely responsible for any errors or omissions contained therein. Landlord’s approvals under this Section 5.9 shall
not be unreasonably withheld, conditioned or delayed.


 


5.10       SURRENDER


 


At the expiration of
the Term or earlier termination of this Lease, without the requirement of any notice, Tenant shall peaceably surrender the Premises
including all alterations and additions thereto and all replacements thereof, including carpeting, any water or electricity meters,
and all fixtures and partitions, in any way bolted or otherwise attached to the Premises (which shall become the property of Landlord)
except for such alterations and additions as Landlord has directed Tenant to remove when Tenant requested Landlord’s approval
for such alterations and additions (other than cabling, which Tenant shall always be required to remove), and Tenant shall leave
the Premises and improvements in the condition in which the same are required to be maintained under Section 5.1, subject
to reasonable wear and tear and damage by casualty subject to the provisions of Section 6.1. Tenant shall, at the time of
termination, remove the goods, effects and fixtures which Tenant is directed or permitted to remove in accordance with the provisions
of this Section 5.10, making any repairs to the Premises and other areas necessitated by such removal and leaving the Premises
in the condition otherwise required by this Section 5.10. Should Tenant fail to remove any of such goods, effects, and fixtures
within ten (10) days after notice by Landlord, the same shall be deemed abandoned by Tenant and may be disposed of by Landlord
at Tenant’s expense. In the event that Landlord terminates this Lease pursuant to Section 7.1 and re-enters and possesses
the Premises in accordance with the terms of this Lease then Landlord may, without notice, store Tenant’s personal property
(and those of any person claiming under Tenant) at the expense and risk of Tenant or, if Landlord so elects, Landlord may sell
such personal property in accordance with the previous sentence and apply the net proceeds to the earliest of installments of Rent
or other charges owing Landlord.

5.11       PERSONAL
PROPERTY TAXES


 


Tenant shall pay promptly
when due all taxes (and charges in lieu thereof) imposed upon Tenant’s personal property in the Premises, (including, without
limitation, fixtures and equipment), no matter to whom assessed. If the Tenant Work to the Premises, whether installed and/or paid
for by Landlord or Tenant and whether or not affixed to the real property so as to become a part thereof, are assessed for real
property tax purposes at a valuation higher than the valuation at which improvements in other space in the Building are assessed,
then the real property taxes and assessment levied against Landlord by reason of such excess assessed valuation shall be deemed
to be taxes levied against personal property of Tenant and shall be paid promptly when due. If the records of the tax assessor
are available and sufficiently detailed to serve as a basis for determining whether said Tenant Work are assessed at a higher valuation,
such records shall be binding on both Landlord and Tenant; otherwise the actual cost of construction shall be the basis for such
determination.


 


5.12       SIGNS


 


No sign, name, placard,
advertisement or notice visible from the exterior of the Premises shall be inscribed, painted or affixed by Tenant on any part
of the Building without the prior written approval of Landlord. All signs or letterings on doors, or otherwise, approved by Landlord,
shall be inscribed, painted or affixed by a person reasonably approved by Landlord and at the sole cost and expense of Tenant.
Landlord, at Landlord’s expense, shall provide and install Building standard signage at the entry doors to the Premises and
in the Building lobby to identify Tenant’s official name and Building address, all such letters and numerals to be in the
Building standard graphics.

CASUALTY AND TAKING


 


6.1         DAMAGE
BY FIRE OR CASUALTY


 


If the Premises or
any part thereof shall be damaged by fire or other insured casualty, then, subject to the last paragraph of this Section 6.1,
Landlord shall proceed with diligence, subject to then applicable statutes, building codes, zoning ordinances and regulations of
any governmental authority, and at the expense of Landlord (but only to the extent of insurance proceeds made available to Landlord
by any mortgagee of the Building) to repair or cause to be repaired all damage to the Premises (except for damage to leasehold
improvements installed by Tenant without notice to and, if required by this Lease, approval by Landlord). All such repairs made
necessary by the negligence or willful misconduct of Tenant shall be made at the Tenant’s expense to the extent that the
cost of such repairs does not exceed the deductible amount in Landlord’s insurance policy. All repairs to and replacements
of property which Tenant is entitled to remove shall be made by and at the expense of Tenant. If the Premises or any part thereof
shall have been rendered unfit for use and occupation hereunder by reason of such damage the Annual Fixed Rent and Additional Rent
for Operating Expenses or a just and proportionate part thereof, according to the nature and extent to which the Premises shall
have been so rendered unfit, shall be abated until the Premises (except as to the property which is to be repaired by or at the
expense of Tenant) shall have been restored as nearly as practicable to the condition in which they were immediately prior to such
fire or other casualty. Landlord shall not be liable for delays in the making of any such repairs which are due to Force Majeure,
nor shall Landlord be liable for any inconvenience or annoyance to Tenant or injury to the business of Tenant resulting from delays
in repairing such damage.


 




    	 	-22-	 



     


    

 


Between thirty (30)
and sixty (60) days after any casualty, Tenant may inquire of Landlord as to Landlord’s estimate of the time period necessary
to complete repair of the Premises. Within thirty (30) days after such inquiry, Landlord shall provide Tenant with Landlord’s
architect’s good faith estimate of the time to complete such repairs and if such estimate (which shall be non-binding) shall
be more than one hundred eighty (180) days from the date of the casualty, then Tenant may terminate this Lease by notice given
to Landlord within thirty (30) days after Tenant’s delivery of Landlord’s architect’s estimate.


 


If Landlord fails to
commence repairs as soon as is reasonably practicable after such damage, and such failure is not due to Force Majeure, and in any
event if Landlord does not commence repairs within sixty (60) days of the casualty, Tenant may elect to terminate this Lease by
notice to Landlord. If Landlord, having commenced such repair, has not completed the repair of such damage by the later of (i)
one hundred eighty (180) days from the occurrence of such damage, or (ii) the date given in any Landlord’s architect’s
repair period estimate under the prior paragraph (the later of such dates is referred to below as the “Outside Restoration
Date”), Tenant may elect to terminate this Lease by notice to Landlord within twenty (20) days of the Outside Restoration
Date, the termination to be effective not less than thirty (30) days after the date on which such termination notice is received
by Landlord. The Outside Restoration Date shall be extended for up to ninety (90) days on account of delays caused by Force Majeure.
Landlord shall not be liable for any inconvenience or annoyance to Tenant or injury to the business of Tenant resulting from delays
in repairing the damage, however if the delays continue more than ninety (90) days beyond the initial Outside Restoration Date,
Tenant may elect to terminate this Lease in the manner provided above.


 


If (i) the Premises
are so damaged by fire or other casualty (whether or not insured) at any time during the last thirty (30) months of the Term that
the cost to repair such damage is reasonably estimated to exceed one-third of the total Annual Fixed Rent payable hereunder for
the period from the estimated completion date of repair until the end of the Term, (ii) at any time the Building (or any portion
thereof, whether or not including any portion of the Premises) is so damaged by fire or other casualty (whether or not insured)
that substantial alteration or reconstruction or demolition of the Building (or a portion thereof) shall in Landlord’s judgment
be required, or (iii) at any time damage to the Building occurs by fire or other insured casualty and any mortgagee shall refuse
to permit insurance proceeds to be utilized for the repair or replacement of such property and Landlord determines not to repair
such damage, then and in any of such events, this Lease and the Term hereof may be terminated at the election of Landlord by a
notice from Landlord to Tenant within sixty (60) days, or such longer period as is required to complete arrangements with any mortgagee
regarding such situation, following such fire or other casualty; the effective termination date pursuant to such notice shall be
not less than thirty (30) days after the day on which such termination notice is delivered to Tenant. In the event of any termination,
the Term shall expire as though such effective termination date were the date originally stipulated in Section 1.1 for the
end of the Term and the Annual Fixed Rent and Additional Rent for Operating Expenses and Taxes shall be apportioned as of such
date.

6.2         CONDEMNATION
- EMINENT DOMAIN


 


In case during the
Term all or any substantial part of the Premises or the Building are taken by eminent domain or Landlord receives compensable damage
by reason of anything lawfully done in pursuance of public or other authority, this Lease shall terminate at Landlord’s election,
which may be made (notwithstanding that Landlord’s entire interest may have been divested) by notice given to Tenant within
ninety (90) days after the election to terminate arises, specifying the effective date of termination. The effective date of termination
specified by Landlord shall not be less than fifteen (15) nor more than thirty (30) days after the date of notice of such termination.
Unless terminated pursuant to the foregoing provisions, this Lease shall remain in full force and effect following any such taking,
subject, however, to the following provisions. If in any such case the Premises are rendered unfit for use and occupation and this
Lease is not terminated, Landlord shall use reasonable diligence (following the expiration of the period in which Landlord may
terminate this Lease pursuant to the foregoing provisions of this Section 6.2) to put the Premises, or what may remain thereof
(excluding any items installed or paid for by Tenant which Tenant may be required to remove pursuant to Section 5.10), into
proper condition for use and occupation and a just proportion of the Annual Fixed Rent and Additional Rent for Operating Expenses
according to the nature and extent of the injury shall be abated until the Premises or such remainder shall have been put by Landlord
in such condition; and in case of a taking which permanently reduces the area of the Premises, a just proportion of the Annual
Fixed Rent and Additional Rent for Operating Expenses and Taxes shall be abated for the remainder of the Term.


 


If the taking of a
part of the Premises substantially and adversely interferes with Tenant’s ability to continue its business operations then
Tenant may terminate this Lease on written notice to Landlord given not more than thirty (30) days after such taking and effective
on the earlier of: (i) the date when title vests; (ii) the date Tenant is dispossessed by the condemning authority; or (iii) sixty
(60) days following notice to Tenant of the date when vesting or dispossession is to occur.


 


6.3         EMINENT
DOMAIN AWARD


 


Except for Tenant’s
relocation expenses (specifically so designated by the court or authority having jurisdiction over the matter) Landlord reserves
to itself any and all rights to receive awards made for damages to the Premises, the Building or 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.

DEFAULT


 


7.1         TERMINATION
FOR DEFAULT OR INSOLVENCY


 


This Lease is upon
the condition that:


 


(a)          if
Tenant shall fail to perform or observe any of Tenant’s covenants, and if such failure shall continue, (i) in the case of
Rent or any sum due Landlord hereunder, for more than three (3) Business Days after written notice, or (ii) in any other case,
after written notice, for more than thirty (30) days (provided that if correction of any such matter reasonably requires longer
than thirty (30) days and Tenant so notifies Landlord within twenty (20) days after Landlord’s notice is given together with
an estimate of time required for such cure, Tenant shall be allowed such longer period, but only if cure is begun and diligently
pursued within such thirty (30) day period and such delay does not cause increased risk of damage to person or property), or


 


(b)          if
more than two (2) notices under clause (a) hereof are given in any twelve month period (failure to pay Rent or any other sum for
more than three (3) Business Days after the particular due date shall have the same effect under this clause (b) as such a notice),
or


 


(c)          if
the leasehold hereby created shall be taken on execution, or by other process of law, or if any assignment shall be made of Tenant’s
property or the property of any guarantor of Tenant’s obligations hereunder (“Guarantor”) for the benefit
of creditors, or


 


(d)          if
a receiver, guardian, conservator, trustee in bankruptcy or similar officer shall be appointed by a court of competent jurisdiction
to take charge of all or any part of Tenant’s or the Guarantor’s property and such appointment is not discharged within
sixty (60) days thereafter or if a petition including, without limitation, a petition for reorganization or arrangement is filed
by Tenant or the Guarantor under any bankruptcy law or is filed against Tenant or the Guarantor and, in the case of a filing against
Tenant only, the same shall not be dismissed within sixty (60) days from the date upon which it is filed,


 


then, and in any of said cases (a) - (d),
Landlord may, immediately or at any time thereafter, elect to terminate this Lease by notice of termination, by entry, or by any
other means available under law and may recover possession of the Premises as provided herein.


 


Upon termination by
notice, by entry, or by any other means available under law, Landlord shall be entitled immediately, in the case of termination
by notice or entry, and otherwise in accordance with the provisions of law to recover possession of the Premises from Tenant and
those claiming through or under the Tenant. Such termination of this Lease and repossession of the Premises shall be without prejudice
to any remedies which Landlord might otherwise have for arrears of Rent or for a prior breach, violation or default of the provisions
of this Lease.


 


Tenant waives any statutory
notice to quit and equitable rights in the nature of further cure or redemption, and Tenant agrees that upon Landlord’s termination
of this’ Lease Landlord shall be entitled to re-entry and possession in accordance with the terms hereof. Tenant further
agrees that it shall not interpose any counterclaim in any summary proceeding or in any action based in whole or in part on non-payment
of Rent unless the counterclaim is a compulsory counterclaim that must be alleged in the same proceeding.

7.2         REIMBURSEMENT
OF LANDLORD’S EXPENSES


 


In the case of termination
of this Lease pursuant to Section 7.1, Tenant shall reimburse Landlord for all reasonable expenses arising out of such termination,
including without limitation, all reasonable costs incurred in collecting amounts due from Tenant under this Lease (including attorneys’
fees, costs of litigation and the like); all expenses incurred by Landlord in attempting to relet the Premises or parts thereof
(including advertisements, brokerage commissions, Tenant’s allowances, costs of preparing space, maintaining or preserving
the Premises after Tenant default, and the like); all of Landlord’s then unamortized costs of special inducements provided
to Tenant (including without limitation Rent holidays, Rent waivers, above building standard leasehold improvements and the like)
and all Landlord’s other reasonable expenditures necessitated by the termination. The reimbursement from Tenant shall be
due and payable immediately from time to time upon notice from Landlord that an expense has been incurred, without regard to whether
the expense was incurred before or after the termination. The provisions of this Section 7.2 shall survive the expiration
or earlier termination of this Lease.


 


7.3         DAMAGES


 


In the event of the
termination of this Lease by Landlord pursuant to Section 7.1, Landlord may elect by written notice to Tenant at any time
following such termination to be indemnified for loss of Rent by a lump sum payment representing the then present value of the
amount of Rent which would have been paid in accordance with this Lease for the remainder of the Term minus the then present value
of the aggregate fair market rent and Additional Rent payable for the Premises for the remainder of the Term following such election
(if less than the Rent payable hereunder), estimated as of the date of Landlord’s election, and taking into account reasonable
projections of vacancy and time required to re-lease the Premises. (For the purposes of calculating the Rent which would have been
paid hereunder for the lump sum payment calculation described herein (x) the last full year’s Additional Rent under Section
2.6 is to be deemed constant for each year thereafter, (y) the Federal Reserve discount rate (or equivalent) shall be used
in calculating present values and (z) in the event that Landlord enters into a third party lease for the Premises after the termination
of this Lease, then the annual fixed rent under such third party lease shall be conclusively deemed to be the fair market rent
for purposes of this Section 7.3.) Should the parties be unable to agree on a fair market rent, the matter shall be submitted,
upon the demand of either party, to the Boston, Massachusetts office of the American Arbitration Association, with a request for
arbitration in accordance with the rules of the Association by a single arbitrator who shall be an MAI appraiser with at least
ten years experience as an appraiser of major office buildings in the Greater Boston area. The parties agree that a decision of
the arbitrator shall be conclusive and binding upon them. Until such time, if any, when Landlord makes the election provided for
in this Section 7.3, Tenant shall indemnify Landlord for the loss of Rent by a payment at the end of each month which would
have been included in the Term, representing the difference between the Rent which would have been paid in accordance with this
Lease (Annual Fixed Rent under Section 2.5, and Additional Rent which would have been payable under Section 2.6 to
be ascertained monthly) and the Rent actually derived from the Premises by Landlord for such month (the amount of Rent deemed derived
shall be the actual amount less any portion thereof attributable to Landlord’s reletting expenses described in Section
7.2 which have not been reimbursed by Tenant thereunder).


 




    	 	-26-	 



     


    

 


All rights and remedies
of Landlord under this Section 7.3 and elsewhere in this Lease shall be distinct, separate and cumulative, and none shall
exclude any other right or remedy of Landlord set forth in this Lease or allowed by law or in equity. Tenant’s obligations
under this Section 7.3 shall survive the expiration or earlier termination of the Term.


 


7.4         MITIGATION


 


In the event the Lease
is terminated pursuant to Section 7.1 and Tenant vacates the Premises, Landlord shall, subject to the provisions of this
Section 7.4, use reasonable efforts to relet the Premises and collect the sums due to Landlord as a result of such reletting;
provided, however, that any obligation imposed by law upon Landlord to relet the Premises shall be subject to the right of Landlord
and its affiliates to lease other available space prior to reletting the Premises and to lease the Building in a harmonious manner
with an appropriate mix of uses, tenants, floor areas and terms of tenancies, and the like.


 


7.5         CLAIMS
IN BANKRUPTCY


 


Nothing herein shall
limit or prejudice the right of Landlord to prove and obtain in a proceeding for bankruptcy, insolvency, arrangement or reorganization,
by reason of the termination, an amount equal to the maximum allowed by a statute or law in effect at the time when, and governing
the proceedings in which, the damages are to be proved, whether or not the amount is greater to, equal to, or less than the amount
of the loss or damage which Landlord has suffered.


 


7.6         INTEREST
ON UNPAID AMOUNTS


 


If any payment of Annual
Fixed Rent, Additional Rent, or other payment due from Tenant to Landlord is not paid when due, then without notice and in addition
to all other remedies hereunder, Tenant shall pay to Landlord interest on such unpaid amount at the rate of eighteen percent (18%)
per annum; provided, however, in no event shall such interest exceed the maximum amount permitted to be charged by applicable law.


 


7.7         LATE
FEE


 


If any payment of Annual
Fixed Rent, Additional Rent, or other payment due from Tenant to Landlord is not paid within five (5) days of such date when due,
then upon the third (3rd) such instance Landlord may, at its option, in addition to all other remedies hereunder, impose a late
charge on Tenant equal to five percent (5%) of the amount in question, which late charge will be due within ten (10) days after
notice as Additional Rent.

MISCELLANEOUS


 


8.1         HOLDOVER


 


If Tenant remains in
the Premises after the termination or expiration of the Term, such holding over shall be as a tenant at sufferance at a rent equal
to the greater of one and one half (1.5) times (i) the Annual Fixed Rent due hereunder for the last month of the Term and (ii)
the fair market rent for the Premises, and otherwise subject to all the covenants and conditions (including obligations to pay
Additional Rent under Section 2.6) of this Lease. Notwithstanding the foregoing, if Landlord desires to regain possession
of the Premises after the termination or expiration hereof, Landlord may, at its option, re-enter and take possession of the Premises
or any part thereof at any time thereafter or by any legal process in force in the state in which the Premises are located.


 


Notwithstanding the
establishment of any tenancy at sufferance following the expiration or earlier termination of the Term, if Tenant fails to vacate
the Premises at the expiration or earlier termination of the Term, Tenant shall save Landlord harmless, indemnify and defend Landlord
against any claim, loss, cost or expense (including reasonable attorneys’ fees by counsel of Landlord’s choice) arising
out of Tenant’s failure promptly to vacate the Premises (or any portion thereof), including without limitation due to the
loss of any opportunity to enter into any advantageous lease or other occupancy agreement.


 


8.2         ESTOPPEL
CERTIFICATES


 


At Landlord’s
request, from time to time, Tenant agrees to execute and deliver to Landlord, within ten (10) days after delivery of such request,

such other facts concerning any provision of the Lease or payments made under the Lease which Landlord or a mortgagee or lender
or a purchaser or prospective purchaser of the Building or any interest therein or any other party may from time to time reasonably
request. Tenant acknowledges that the execution and delivery of such certificates in connection with a financing or sale in a prompt
manner constitute requirements of Landlord’s financing and/or property dispositions. Without limitation of the foregoing,
Tenant agrees to execute instruments reasonably requested by lenders to acknowledge such tenancy in recordable form, within ten
(10) days after Landlord’s request, correcting as appropriate any representations which are not then correct.

United States by notice to the other.


 


8.4         LANDLORD’S
RIGHT TO CURE


 


Subject to prior notice
to Tenant and the expiration of any applicable cure period (except in the case of emergency or Landlord’s reasonable determination
of the existence of danger to health or property, in which case no notice or cure period shall be required), Landlord may, but
need not, cure any failure by Tenant to perform its obligations under this Lease. Whenever Landlord chooses to do so, Tenant shall
pay all costs and expenses incurred by Landlord in curing any such failure, including, without limitation, reasonable attorneys’
fees together with an administrative charge equal to five percent (5%) of such costs and expenses (or such higher percentage as
may then be customary with respect to first class office buildings in the metropolitan area in which the Premises are located)
and interest as provided in Section 7.6.

8.7         WAIVER


 


The failure of Landlord
or of Tenant to seek redress for violation of, or to insist upon strict performance of, any covenant or condition of this Lease,
or, with respect to such failure of Landlord, any of the Rules and Regulations referred to in Section 5.4, whether heretofore
or hereafter adopted by Landlord, shall not be deemed a waiver of such violation nor prevent a subsequent act, which would have
originally constituted a violation, from having all the effect of an original violation, nor shall the failure of Landlord to enforce
any of said Rules and Regulations against any other tenant of the Building be deemed a waiver of any such Rules or Regulations.
The receipt by Landlord of Annual Fixed Rent or Additional Rent with knowledge of the breach of any covenant of this Lease shall
not be deemed waiver of such breach. No provision of this Lease shall be deemed to have been waived by Landlord, or by Tenant,
unless such waiver be in writing signed by the party to be charged. No consent or waiver, express or implied, by Landlord or Tenant
to or of any breach of any agreement or duty shall be construed as a waiver or consent to or of any other breach of the same or
any other agreement or duty.


 


8.8         ACCORD
AND SATISFACTION


 


No acceptance by Landlord
of a lesser sum than the Annual Fixed Rent and Additional Rent then due shall be deemed to be other than on account of the earliest
installment of such Rent due, nor shall any endorsement or statement on any check or any letter accompanying any check or payment
as Rent be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s
right to recover the balance of such installment or pursue any other remedy provided in this Lease. The delivery of keys to Landlord
shall not operate as a termination of this Lease or a surrender of the Premises.


 


8.9         REMEDIES
CUMULATIVE


 


The specific remedies
to which Landlord may resort under the terms of this Lease are cumulative and are not intended to be exclusive of any other remedies
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 or conditions of this Lease or to a decree compelling specific performance of any
such covenants or conditions.


 


8.10       PARTIAL
INVALIDITY


 


If any term of this
Lease, or the application thereof to any person or circumstance, shall to any extent be invalid or unenforceable, the remainder
of this Lease, or the application of such term to persons or circumstances other than those as to which it is invalid or unenforceable,

LANDLORD’S LIABILITY AND ASSIGNMENT FOR FINANCING


 


9.1         LANDLORD’S
LIABILITY


 


Tenant agrees to look
only to Landlord’s interest in the Land and Building and the proceeds therefrom for satisfaction of any claim against Landlord
hereunder or under any other instrument related to the Lease (including any separate agreements among the parties and any notices
or certificates delivered by Landlord) and not to any other property or assets of Landlord. If Landlord from time to time transfers
its interest in the Land and Building (or part thereof which includes the Premises), then from and after each such transfer Tenant
shall look solely to the interests in the Land and Building of each of Landlord’s transferees for the satisfaction of any
claim relating to non-performance of all of the obligations of Landlord hereunder (or under any related instrument). The obligations
of Landlord shall not be binding on any partners, mortgagees, members, managers, directors, officers, trustees, or beneficiaries
of Landlord or of any successor, individually, but only upon Landlord’s or such successor’s interest described above.


 


Except for the negligence
or willful misconduct of Landlord or any of the Indemnitees (as such term is defined in Section 5.5.1), Landlord shall not
be liable to Tenant and Tenant hereby waives all claims against Landlord for any injury or damage to any person or property whatsoever.
In no event shall Landlord ever be liable for any indirect or consequential damages. It is expressly agreed by Landlord and Tenant
that business interruption costs and expenses are indirect and consequential damages under the terms of this Lease and no other
property assets of Landlord shall be subject to levy, execution or other enforcement procedures for satisfaction of any judgment
or decree in favor of Tenant. Notwithstanding anything to the contrary in this Lease, Tenant shall not be liable to Landlord under
this Lease for indirect or consequential damages except under Section 5.2 and provided further that the parties acknowledge
that damages set forth in Article VII shall be deemed direct damages and shall not be construed to be consequential damages.


 


9.2         ASSIGNMENT
OF RENTS


 


If, at any time and
from time to time, Landlord assigns this Lease or the Rents payable hereunder to the holder of any mortgage on the Building, or
to any other party for the purpose of securing financing (the holder of any such mortgage and any other such financing party are
referred to herein as the “Financing Party”), whether such assignment is conditional in nature or otherwise,
the following provisions shall apply:


 


(a)          Such
assignment to the Financing Party shall not be deemed an assumption by the Financing Party of any obligations of Landlord hereunder
unless such Financing Party shall, by written notice to Tenant, specifically otherwise elect;


 


(b)          Except
as provided in Section 9.2(a) above and Section 9.2(c) below, the Financing Party shall be treated as having assumed
Landlord’s obligations hereunder (subject to Section 9.1) only upon foreclosure of its mortgage (or voluntary conveyance
by deed in lieu thereof) and the taking of possession of the Premises from and after foreclosure and, with respect to obligations
regarding return of the Security Deposit, only upon receipt of the funds constituting such Security Deposit;


 




    	 	-34-	 



     


    

 


(c)          Subject
to Section 9.1, the Financing Party shall be responsible for only such breaches under the Lease by Landlord which occur
during the period of ownership by the Financing Party after such foreclosure (or voluntary conveyance by deed in lieu thereof)
and taking of possession, as aforesaid; and


 


(d)          In
the event Tenant alleges that Landlord is in default under any of Landlord’s obligations under this Lease, Tenant agrees
to give any Financing Party, by registered mail, a copy of any notice of default which is served upon the Landlord, provided that
prior to such notice, Tenant has been notified, in writing, (whether by way of notice of an assignment of lease, request to execute
an estoppel letter, or otherwise) of the address of such Financing Party. Tenant further agrees that if Landlord shall have failed
to cure such default within the time provided by law or such additional time as may be provided in such notice to Landlord, such
Financing Party shall have sixty (60) days after the last date on which Landlord could have cured such default within which such
Financing Party will be permitted to cure such default. If such default cannot be cured within such sixty (60) day period, then
such Financing Party shall have such additional time as may be necessary to cure such default, if within such sixty (60) day period
such Financing Party has commenced and is diligently pursuing the remedies necessary to effect such cure (including, but not limited
to, commencement of foreclosure proceedings, if necessary, to effect such cure), in which event Tenant shall have no right with
respect to such default while such remedies are being diligently pursued by such Financing Party.


 


In all events, any
liability of a Financing Party shall be limited to the interest of such Financing Party in the Land and Building, and in no event
shall a Financing Party ever be liable for any indirect or consequential damages.


 


Tenant hereby agrees
to enter into such reasonable agreements or instruments as may be requested from time to time in confirmation of the foregoing.

SUBORDINATION AND NON-DISTURBANCE


 


This Lease shall be
subject and subordinate to any first mortgage and to any junior mortgage that has been approved by the first mortgagee that may
now or hereafter be placed upon the Building and/or the Land and to any and all advances to be made under such mortgages and to
the interest thereon, and all renewals, extensions and consolidations thereof. Any mortgagee may elect to give this Lease priority

may have arisen or intervened in the period between the recording of the mortgages and the execution of this Lease, or any lien
or judgment which may arise any time under the terms of this Lease. In the event of such election and upon notification by such
mortgagee, this Lease shall be deemed prior in lien to the said mortgage. This Article X shall be self-operative, but in
confirmation thereof, Tenant shall execute and deliver whatever instruments as may be reasonably required by the first mortgagee
or junior mortgagee to acknowledge such subordination or priority in a recordable form.

ROOF SPACE


 


11.1       ANTENNA.


 


(a)          From
the Term Commencement Date until the expiration or earlier termination of this Lease, Tenant shall have a license to use a portion
of the roof of the Building and enjoy 24-hour access thereto (the “Rooftop License”) at a technologically sufficient
location to be proposed by Tenant and approved by Landlord (the “Rooftop Installation Area”). The Rooftop Installation
Area is to be used by Tenant solely for the installation, operation, maintenance, repair and replacement during the Term of this
Lease of an antenna thirty inches (36”) in diameter and other related communications equipment, including one two-inch (2”)
conduit connecting the antenna to the Premises, to be located in a vertical chase mutually designated by Landlord and Tenant (collectively,
the “Antenna”). Tenant’s installation and operation of the Antenna and its obligations with respect thereto
shall be all in accordance with the terms, provisions, conditions and agreements contained in this Lease.


 


(b)          Tenant
shall install the Antenna in the Rooftop Installation Area at its sole cost and expense, at such times and in such manner as Landlord
may reasonably designate and in accordance with all of the applicable provisions of this Lease, including, without limitation,
Section 5.9). Landlord shall not be obligated to perform any work or incur any expense to prepare the Rooftop Installation
Area for Tenant’s use thereof.


 


(c)          Tenant
shall not install or operate the Antenna until it receives prior written approval from Landlord, which Landlord agrees shall not
be unreasonably withheld, conditioned or delayed, provided and on the condition that Tenant complies with all of the requirements
of this Lease including without limitation Section 5.9 and this Article XI. Prior to commencing installation of the
Antenna, Tenant shall provide Landlord with (i) copies of all required permits, licenses and authorizations which Tenant will obtain
at its own expense and which Tenant will maintain at all times during the operation of the Antenna; and (ii) a certificate of insurance
evidencing insurance coverage as required by this Lease and any other insurance reasonably required by Landlord for the installation
and operation of the Antenna. Tenant agrees to reimburse Landlord for reasonable expenses incurred in connection with the review
and approval of Tenant’s plans showing the proposed installation of the Antenna.


 




    	 	-36-	 



     


    

 


(d)          Tenant
shall pay to Landlord as Additional Rent (the “Antenna Rent”), all applicable taxes or governmental charges,
fees, or impositions imposed upon Landlord and arising out of Tenant’s use of the Rooftop Installation Area, and the amount,
if any, by which Landlord’s insurance premiums increase as a result of the installation of the Antenna.


 


(e)          Tenant
covenants that Tenant shall repair any damage to the roof and the Building caused by the installation or operation of the Antenna.


 


(f)          Tenant
covenants and agrees that the installation, operation and removal of the Antenna and appurtenant equipment and cabling will be
at its sole risk. Tenant agrees to indemnify and defend Landlord and all other Indemnitees (as defined in Section 5.5.1)
against all claims, actions, damages, liabilities and expenses including reasonable attorneys’ fees by counsel of Landlord’s
choice in connection with the loss of life, personal injury, damage to property or business or any other loss or injury or as a
result of any litigation arising out of the installation, use, operation or removal of the Antenna and appurtenant equipment and
cabling, except to the extent the foregoing is caused by the gross negligence or willful misconduct of Landlord or the Indemnitees.


 


(g)          Landlord,
at its sole option upon not less than sixty (60) days’ prior written notice, shall have the right to revoke the Rooftop License
at any time prior to the expiration of the Term of this Lease, and require Tenant to terminate the operation of the Antenna if
(1) the Antenna is causing physical damage to the structural integrity of the Building, or (2) the Antenna is interfering with
any telecommunications, mechanical or other systems either located or servicing the Building (whether belonging to or utilized
by Landlord or any other tenant or occupant of the Building) or located at or servicing any building, premises or location in the
vicinity of the Building, or (3) the installation, existence, maintenance and operation of the Antenna (i) constitutes a violation
of any applicable laws, ordinances, rules, order, regulations, etc. of any federal, state, county and municipal authorities having
jurisdiction thereover or (ii) does not conform to industry technical specifications. Notwithstanding the foregoing however, if
Tenant can correct the damage or disturbance caused by the Antenna to Landlord’s reasonable satisfaction, Tenant may restore
the operation. If the Antenna is not corrected and restored to operation within sixty (60) days, Landlord, at its sole option,
may require that Tenant remove the Antenna and appurtenant equipment and cabling at its own expense.


 


(h)          The
sole use and purpose of this Rooftop License shall be to serve the communication needs of Tenant within the Building. Tenant is
expressly forbidden to serve other tenants or occupants of the Building, to serve any locations outside the Building, or to resell
any communications services without the prior written consent of Landlord, which consent may be granted or withheld at Landlord’s
sole discretion. In the event Tenant shall attempt to resell, license, lease or otherwise provide use of the Antenna to any person
or entity, except in connection with a Permitted Transfer, without Landlord’s prior written consent, then the Rooftop License
shall immediately terminate and Landlord shall have the right to disconnect the Antenna and appurtenant equipment and cabling and,
in accordance with the provisions of subsection (h) hereof, require Tenant to remove the Antenna and appurtenant equipment and
cabling and to restore the Building to the condition as existed prior to the installation thereof, all at Tenant’s sole cost
and expense.


 




    	 	-37-	 



     


    

 


(i)          Within
fifteen (15) days following the expiration or earlier termination of the Lease or the permanent termination of the operation of
the Antenna by Tenant, Tenant shall, at its sole cost and expense, (i) remove the Antenna from the Rooftop Installation Area and
the Building in accordance with the terms hereof, (ii) leave the Rooftop Installation Area in good order and repair, reasonable
wear and tear excepted and (iii) pay all amounts due and owing with respect to the Rooftop License up to the date of the termination
thereof. If Tenant does not remove the Antenna when so required, the Antenna shall become Landlord’s property and, at Landlord’s
election, Landlord may remove and dispose of the Antenna and charge Tenant for all costs and expenses incurred as Additional Rent.
Notwithstanding that Tenant’s use of the Rooftop Installation Area shall be subject at all times to and shall be in accordance
with the terms, covenants, conditions and agreements contained in this Lease, the Rooftop Installation Area shall not be deemed
part of the Premises. All Tenant obligations under this Section 11.1 shall survive the expiration of the Term or the earlier
termination of this Lease.

Landlord’s Initial Construction


 


		1.	Plans and Specifications.



 


(a)         Preparation
of Plans. Landlord has prepared a plan (“Landlord’s Plans”) attached hereto as Exhibit B-1, which Tenant
hereby unconditionally approves. Landlord shall perform Landlord’s Initial Construction consistent with Landlord’s
Plans using building standard materials and finishes


 


(b)         Change
Orders. Landlord’s Plans shall not be changed or modified except as set forth herein. If Tenant requests a change in
Landlord’s Plans, Landlord shall not unreasonably withhold its consent to said change provided that it shall not be deemed
unreasonable for Landlord to withhold consent to any change in Landlord’s Plans that in Landlord’s sole opinion (i)
will cause any delay in the completion of Landlord’s Initial Construction (as hereinafter defined), (ii) cause any additional
cost or expense to Landlord, (iii) in any manner affect any structural component of the Building (including, without limitation,
exterior walls, exterior windows, core walls, roofs, or floor slabs), (iv) in any respect be incompatible with the electrical,
mechanical, or plumbing components or systems of the Building, (v) affect in any respect other space in the Building other than
the Premises, including the exterior of the Building, (vi) diminish the value of the Premises for any general purpose office use,
or (vii) require any unusual expense to readapt the Premises for any general purpose office use. With respect to clauses (i) and
(ii) above, Landlord may, but shall not be obligated to, grant its consent provided Tenant agrees to pay for any and all costs
associated therewith.


 


2.        Completion
of Landlord’s Initial Construction.


 


(a)       Construction
of Premises. Landlord shall exercise reasonable efforts to substantially complete the work specified in Landlord’s Plans
(“Landlord’s Initial Construction”) necessary to prepare the Premises for Tenant’s occupancy on
or before the Estimated Term Commencement Date specified in Section 1.1 of this Lease, subject to Tenant’s Delays
(as hereinafter defined) and Force Majeure, as such term is defined in Section 4.2 of this Lease.


 


(b)       Substantial
Completion. The Premises shall be deemed ready for occupancy on that day (the “Substantial Completion Date”) on
which Landlord’s Initial Construction is “Substantially Complete,” defined to mean that Landlord’s Initial
Construction has been completed except for minor items of construction, mechanical and electrical adjustment or other work which
Landlord is able to complete after Tenant has occupied the Premises without unreasonably interfering with Tenant’s use thereof,
as evidenced by an architect’s written certification and the issuance of a valid certificate of occupancy (which may be temporary
or permanent) from the City of Wakefield for the Premises or such other permit or approval entitling Tenant to occupy the Premises
for the Permitted Uses.


 


3.        Intentionally
Omitted


 




     


     


    

 


		4.	Excess Work.



 


All Landlord’s
Initial Construction performed under any Change Order, the cost of which exceeds the cost to perform Landlord’s Initial Construction
in accordance with Landlord’s Plans shall be “Excess Work.” Tenant may seek to reduce the cost of Landlord’s
Initial Construction by Change Order under Section 1(b) above. All Excess Work shall be performed by Landlord at the sole
expense of Tenant.


 


		5.	Tenant’s Delay.



 


(a)       Any
delay that shall occur in the Substantial Completion Date as the result of the following shall be a Tenant’s Delay:


 


		(i)	any request by Tenant that Landlord delay in the commencement or completion of Landlord’s
Initial Construction for any reason;



 


		(ii)	any change made or requested by Tenant in any of Landlord’s Plans



 


		(iii)	any special requirements of Tenant not in conformity with Landlord’s Plans;



 


		(iv)	any other act or omission of Tenant or its members, managers, officers, directors, agents, servants,
contractors, architects, engineers, or employees; or



 


		(v)	any reasonably necessary rescheduling of the sequence of any of Landlord’s Initial Construction
due to any of the causes for delay referred to in clauses (i), (ii), (iii), and (iv) of this paragraph (a) of Section 5.



 


(b)        If
any delay in the Substantial Completion Date is the result of Force Majeure and such delay would not have occurred but for any
of Tenant’s Delays described in paragraph (a) of this Section 5, such delay shall be deemed added to Tenant’s
Delays described in that paragraph.


 


(c)        In
addition to Landlord’s other rights and remedies under prevailing circumstances, the Term Commencement Date shall automatically
be extended for the period of any delays caused by Tenant’s Delay(s) or Force Majeure, but the number of days of initial
rent abatement to which Tenant is entitled under Section 1.1 shall be reduced by the number of days the Term Commencement
Date is delayed as a result of a Tenant Delay.


 


(d)        If,
as a result of Tenant’s Delay(s), the Substantial Completion Date is delayed in the aggregate for more than sixty (60) days,
Landlord may (but shall not be required to) at any time thereafter terminate this Lease by giving written notice of such termination
to Tenant, and thereupon this Lease shall forthwith terminate without further liability or obligation on the part of either party,
except that Tenant shall pay to Landlord the damages suffered by Landlord by reason of such Lease termination including, without
limitation, the cost theretofore incurred by Landlord in performing and, if applicable, demolishing Landlord’s Initial Construction,
plus an amount equal to Landlord’s out-of-pocket expenses incurred in connection with this Lease, including, without limitation,
brokerage and legal fees, together with any amount required to be paid pursuant to paragraph (a) of this Section 5, through the
effective termination date.


 




     


     


    

 


		6.	Conclusiveness of Landlord’s Performance.



 


Tenant shall have no
claim that Landlord has failed to perform any of Landlord’s Initial Construction, unless Tenant shall have given Landlord
notice, not later than sixty (60) days following the Substantial Completion Date, or, in the case of latent defects, not later
than the earlier of (a) eleven (11) months following the Substantial Completion Date and (b) the date Tenant knew or should have
known about such latent defect, of respects in which Landlord has not performed Landlord’s Initial Construction. Except for
Landlord’s Initial Construction, the Premises are being leased in their condition “as is” without representation
or warranty by Landlord.


 


		7.	Entry Prior to Commencement.



 


If and as long as Tenant
does not interfere in any way with the construction process (by causing disharmony, scheduling or coordination difficulties, etc.),
Tenant may, pursuant to the provisions of Section 3.2 of this Lease and at Tenant’s sole risk and expense, enter the
Premises up to thirty (30) days prior to the Substantial Completion Date for the purpose of installing Tenant’s decorations,
movable furnishings, cabling, wiring and business fixtures and equipment. The determination of any such interference by Landlord
shall be conclusive. Prior to the Substantial Completion Date, upon Tenant’s written request, Tenant may conduct a walk-through
of the Premises accompanied by a representative of Landlord.


 


Prior to the Term Commencement
Date Tenant shall comply with and perform, and shall cause its employees, agents, contractors, subcontractors, material suppliers
and laborers to comply with and perform, all Tenant’s obligations under this Lease except the obligations to pay Annual Fixed
Rent and Additional Rent and other obligations, the performance of which would be clearly incompatible with the installation of
decorations, movable furnishings, cabling, wiring and business fixtures and equipment pursuant hereto.


 


		8.	Tenant Contractors.



 


Any independent contractor
of Tenant (or any employee or agent of Tenant) performing any work in the Premises prior to the Term Commencement Date if and to
the extent permitted by Landlord pursuant to the provisions of Section 3.2 of this Lease shall be a “Tenant Contractor”
and shall be subject to all of the terms, conditions and requirements contained in the Lease. Neither Tenant nor any Tenant Contractor
shall interfere in any way with construction of, nor damage, Landlord’s Initial Construction, and shall do all things reasonably
requested by Landlord to expedite construction of Landlord’s Initial Construction. Without limitation, Tenant shall require
each Tenant Contractor to adjust and coordinate any work or installation in or to the Premises to meet the schedule or requirements
of other work being performed by or for Landlord throughout the Building, which shall in all cases have precedence. If Tenant or
any Tenant Contractor fails so to adjust to the schedule or requirements of Landlord, then Landlord may immediately by notice to
Tenant terminate permission previously granted to Tenant to enter the Premises prior to the Term Commencement Date. Neither Tenant
nor any Tenant Contractor shall cause any labor disharmony, and Tenant shall be responsible for all costs required to produce labor
harmony in connection with an entry under this Section. In all events, Tenant shall indemnify the Indemnitees in the manner provided
in Section 5.5.1 of this Lease against any claim, loss or cost arising out of any interference with, or damage to, Landlord’s
Initial Construction or any other work in the Building, or any delay thereto, or any increase in the cost thereof on account in
whole or in part of any act, omission, neglect or default by Tenant or any Tenant Contractor. Without limiting the generality of
the foregoing, to the extent that the commencement or performance of Landlord’s Initial Construction is delayed on account
in whole or in part of any act, omission, neglect, or default by Tenant or any Tenant Contractor, then such delay shall constitute
a Tenant Delay as provided herein.


 




     


     


    

 


Any requirements of any
such Tenant Contractor for services from Landlord or Landlord’s contractor, such as hoisting, electrical or mechanical needs,
shall be paid for in advance by Tenant and arranged between such Tenant Contractor and Landlord or Landlord’s contractor.
Should the work of any Tenant Contractor depend on the installed field conditions of any item of Landlord’s Initial Construction,
such Tenant Contractor shall ascertain such field conditions after installation of such item of Landlord’s Initial Construction.
Neither Landlord nor Landlord’s contractor shall ever be required or obliged to alter the method, time or manner for performing
Landlord’s Initial Construction or work elsewhere in the Building, on account of the work of any such Tenant Contractor.
Should Landlord’s contractor, including subcontractors working under such contractor, damage or delay the work of any Tenant
Contractor, then such Tenant Contractor, by entering on the Premises, shall be deemed to have agreed not to prosecute any claim
against Landlord, but shall look solely to Landlord’s contractor (or such contractor’s subcontractors) that allegedly
caused the damage or delay. If any such Tenant Contractor ever makes a claim against any Indemnitee (as such term is defined in
Section 5.5.1 of this Lease) directly, then Tenant shall indemnify such Indemnitee in the manner provided in the Lease against
such claim so long as such Tenant Contractor’s loss was not caused solely and directly by the gross negligence or willful
and wrongful act of such Indemnitee. Tenant shall cause each Tenant Contractor performing work on the Premises to clean up regularly
and remove its debris from the Premises and Building. If any Tenant Contractor fails so to clean up, then Landlord may cause its
contractor to clean up and remove debris, and Tenant shall pay all costs (including administrative costs) of such cleanup and removal.

Guaranty 


 


201 Edgewater Drive


 


WAKEFIELD, MASSACHUSETTS


 


Guaranty dated as of
April 30, 2012, by the undersigned SDL, plc, a corporation registered in England and Wales (“Guarantor” hereunder),
having offices at Globe House, Clivemont Road Maidenhead, SL6 7DY, United Kingdom, on behalf of itself its subsidiaries and affiliated
entities.


 


BACKGROUND


 


101 Edgewater LLC,
a Delaware limited liability company, (“Landlord”) and XyEnterprise, Inc., a Delaware corporation (“Tenant”),
entered into a lease dated as of April 30, 2012 for space at 201 Edgewater Drive, Wakefield, Massachusetts (as the same may be
amended hereafter from time to time, the “Lease”).


 


It is intended that
Guarantor shall guarantee all of Tenant’s obligations under the Lease pursuant to this Guaranty. Capitalized terms used and
not defined in this Guaranty shall have the same meanings as in the Lease.


 


AGREEMENT


 


1.          Guarantor
hereby unconditionally guarantees to Landlord, its successors and assigns, the full performance and observance of all the covenants,
conditions and agreements in the Lease provided to be performed and observed by Tenant, its successors and assigns, for the entire
Term, as the same may be extended or renewed and to any holdover term thereafter, for the entire Premises, as the same may be expanded,
contracted, relocated, sublet, licensed and/or assigned (voluntarily or otherwise), and whether or not Landlord has consented to
same. Guarantor expressly agrees that the validity of this Guaranty and the obligations of Guarantor under this Guaranty shall
not be terminated or in any way affected or impaired by reason of any amendment to the Lease, but shall continue in full force
and effect with respect to the Lease as the Lease may be amended from time to time. Guarantor further expressly agrees that the
validity of this Guaranty and the obligations of Guarantor under this Guaranty shall not be terminated or in any way affected or
impaired by reason of the assertion by Landlord against Tenant of any of the rights or remedies reserved to Landlord pursuant to
the provisions of the Lease, or by reason of the delay, waiver or failure by Landlord to enforce any of the terms, covenants or
conditions of the Lease, this Guaranty, or any other guaranty of the Lease (if any), or by reason of the granting of any indulgence
or extension to Tenant, or Guarantor, or to any other guarantor (if any), all of which may be given or done by Landlord from time
to time without notice to Guarantor. Guarantor waives notice of non-payment of rent, additional charges, or any other amounts to
be paid by Tenant under the Lease, and waives notice of default or non-performance of any of Tenant’s other covenants, conditions
and agreements contained in the Lease. Guarantor further waives, to the fullest extent permitted by law, any and all legal, equitable
and/or surety defenses whatsoever to which Guarantor might otherwise be entitled other than: (1) that Guarantor has fully performed
all of its obligations under this Guaranty, and (2) that Tenant has fully performed all of its obligations under the Lease (determined
without regard to any relief of Tenant from its obligations by operation of law or otherwise).


 




    	 	i	 



     


    

 


2.          Guarantor
agrees that its liability under this Guaranty shall be primary and joint and several with Tenant, any other guarantor (if any),
and any other party liable for Tenant’s obligations under the Lease, and that in any right of action that shall accrue to
Landlord under the Lease, Landlord may, at its option, proceed against Guarantor, without having commenced any action or having
obtained any judgment against Tenant, any other guarantor, or any other party liable for Tenant’s obligations under the Lease.


 


3.          Guarantor
represents and warrants to Landlord that Guarantor has a material financial interest in the Tenant. If Guarantor is a corporation
or other entity, Guarantor represents and warrants to Landlord that the individual or individuals executing this Guaranty on behalf
of Guarantor is or are duly authorized to execute and deliver this Guaranty on behalf of Guarantor, that this Guaranty is a valid
and binding obligation of Guarantor enforceable in accordance with its terms, and that this Guaranty violates no law, rule, regulation,
agreement or contract applicable to or binding on Guarantor. In any proceeding, the books and records of Landlord shall be prima
facie evidence of the obligation of Guarantor.


 


4.          Guarantor
further agrees as follows:


 


a.         Any
and all claims of any nature that Guarantor may now or hereafter have against Tenant are hereby subordinated to the full and final
cash payment to Landlord of all obligations under the Lease and under this Guaranty. Without limiting the generality of the foregoing,
prior to the full and final cash payment to Landlord of all obligations under the Lease and under this Guaranty, Guarantor agrees
that it shall not: (i) make any claim of liability of Tenant to any Guarantor or assert any set-off or counterclaim against Tenant
whether by reason of paying any sum due or recoverable under this Guaranty (whether or not demanded by Landlord) or under the Lease,
or by any other means or on any other ground; or (ii) attempt to prove in competition with Landlord any claim regarding any payment
made under this Guaranty or under the Lease; or (iii) have the benefit of any counterclaim or proof of claim or dividend or payment
by or on behalf of Tenant or the benefit of any other security for any obligation. Guarantor waives any rights of subrogation,
any rights to enforce any right or remedy of Landlord against Tenant, and any right to participate in any collateral held or payment
received by Landlord.


 


b.         In
order to carry out the terms and intent of this Guaranty more effectively, Guarantor agrees to do all acts necessary or convenient
to preserve for Landlord the benefits of the foregoing subordination provisions and promptly will execute all agreements and instruments
that Landlord may from time to time reasonably request for that purpose, and Guarantor hereby assigns, transfers and sets over
to Landlord all claims against the Tenant that Guarantor now has or Guarantor hereafter may have (“Guarantor’s Claims”)
and, without imposing upon the Landlord any duty with respect to preservation, protection or enforcement of any Guarantor’s
Claims, constitutes and appoints Landlord the true and lawful attorney of Guarantor for the purposes of collecting and/or proving
Guarantor’s Claims, of accepting or rejecting, to the extent to which Guarantor otherwise would be entitled to accept or
reject any plan of reorganization or arrangement in any proceedings affecting Tenant, and in general of doing any act in connection
with any proceedings affecting Tenant which Guarantor might otherwise do. Landlord shall account to Guarantor for any dividends
or payments received in excess of the amount necessary fully and finally to satisfy in cash all claims arising out of the Lease
and the Guaranty including, without limitation, all interest and expenses of collection.


 




    	 	ii	 



     


    

 


c.         In
the event of avoidance, disgorgement, reduction, reconveyance or recovery of any payment from Tenant to Landlord as a preference
under any laws relating to the bankruptcy, reorganization or liquidation of debtors, or as a so-called fraudulent conveyance, or
under any other applicable law, Landlord shall be entitled to recover on demand the amount of such payment from Guarantor as if
such payment had never been made by Tenant.


 


5.          Guarantor
shall furnish to Landlord copies of its financial statements as set forth in Section 8.18 of the Lease. So long as Guarantor is
a publicly-traded company that makes public reports as required by the Listing Rules of the London Stock Exchange, those publicly-available
reports shall satisfy all obligations of Guarantor under this Section 5.


 


6.          No
assignment or transfer of the Lease shall operate to extinguish or diminish the liability of Guarantor under the Guaranty. Guarantor
further agrees to pay to Landlord, upon demand, all costs and expenses, including without limitation reasonable attorneys’
fees and expert fees and costs, of preparing to enforce or of enforcing any obligations under this Guaranty.


 


7.          Guarantor’s
liability hereunder shall be ascertained as though the Guarantor was itself the tenant under the Lease, jointly and severally with
Tenant, and the Guarantor’s obligations hereunder shall not be affected or impaired by any relief of Tenant from Tenant’s
obligations under the Lease by operation of law or otherwise including, without limitation, in connection with proceedings under
the bankruptcy laws now or hereafter enacted, or similar laws for the relief of debtors.


 


8.          Guarantor
hereby irrevocably and unconditionally submits to personal jurisdiction in the Commonwealth of Massachusetts over any suit, action
or proceeding arising out of this Guaranty or out of the Lease, and Guarantor hereby waives any right to object to personal jurisdiction
within the Commonwealth of Massachusetts. The initiation of any suit, action or proceeding by Landlord against any Guarantor or
any property of Guarantor in any other jurisdiction shall not constitute a waiver of the agreements contained herein that the law
of the Commonwealth of Massachusetts shall govern the rights of Landlord and the rights and obligations of Guarantor under this
Guaranty, and that Guarantor submits to personal jurisdiction within the Commonwealth of Massachusetts. Guarantor hereby waives
any right to a trial by jury for any claim arising under this Guaranty.


 


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


 




    	 	iii	 



     


    

 


10.         This
Guaranty is governed by, and all disputes arising under or in connection with this Guaranty shall be resolved in accordance with,
the laws of Massachusetts (to the exclusion of its conflict of laws rules), except that this arbitration clause and any arbitration
hereunder shall be governed by the Federal Arbitration Act, Chapters 1 and 2. Any controversy or claim arising out of or relating
to this Guaranty, or the breach thereof, shall be settled by arbitration administered by the American Arbitration Association in
accordance with its International Arbitration Rules. There shall be one (1) arbitrator. The language of the arbitration shall be
English. The place of the arbitration shall be (and the hearings shall be conducted in) Boston, Massachusetts. The arbitrator is
authorized to include in his or her award an allocation to any party of such costs and expenses, including attorneys’ fees,
as the arbitrator shall deem reasonable. Judgment on the award(s) rendered by the arbitrator may be entered into any court having
jurisdiction thereof. The parties hereby waive all objection which it may have at any time to the laying of venue of any proceedings
brought in such courts, waives any claim that such proceedings have been brought in an inconvenient forum and further waives the
right to object with respect to such proceedings that any such court does not have jurisdiction over such party.
