required by the terms of this Sublease and the Prime Lease. 
 3. IMPROVEMENTS. 
 A. Provided that Subtenant shall not unreasonably interfere with Sublandlord’s continued use and occupancy of the Remaining Premises, Subtenant shall
expeditiously perform all of the construction of the interior improvements to the Sublease Premises necessary for Subtenant’s use of the Sublease Premises as contemplated hereunder and described on Exhibit E hereto (the “Subtenant’s

rules, regulations and insurance requirements applicable thereto and (iii) those certain plans and specifications to be constructed on behalf of Subtenant by a reputable contractor and subject to the reasonable approval by Sublandlord (the

 2 

 B. Subtenant hereby covenants and agrees, at its sole cost and expense and in accordance with the terms
and provision of this Sublease, to initiate and thereafter diligently prosecute to completion the Subtenant’s Work. Subtenant further acknowledges and agrees the Sublandlord shall have no obligation to perform any portion of the
Subtenant’s Work, all of such work being the sole responsibility of Subtenant hereunder. 
 C. Sublandlord shall provide to Subtenant an
allowance of $256,455.00 (the “Subtenant Allowance”) to be applied towards the cost of the Subtenant’s Work (including, without limitation, the architect’s fee, improvements, tel/data wiring, moving and all other reasonable
occupancy expenses in connection therewith). It is understood and agreed that the Subtenant Allowance (or portions thereof) will be made available to Subtenant within thirty (30) days after Subtenant provides Sublandlord with invoices showing
the actual cost of performing the applicable portion of the Subtenant’s Work, and that such disbursement may occur at any time after the execution of this Sublease and commencement of the Term. To the extent the costs of the Subtenant’s
Work exceed the Subtenant Allowance, Subtenant shall be solely responsible for such excess costs and shall promptly pay the difference to the appropriate contractors and suppliers. 
 D. Notwithstanding the foregoing, Sublandlord shall be under no obligation to apply any portion of the Subtenant Allowance for any purposes other than as
provided in this. Section 3, nor shall Sublandlord be deemed to have assumed any obligations, in whole or in part, of Subtenant to any contractors, subcontractors, suppliers, workmen or materialmen. In addition, Sublandlord shall not be
obligated to make any application of any portion of the Subtenant Allowance (i) for so long as (x) there shall be an existing default of Subtenant or (y) there are any liens which are not bonded to the reasonable satisfaction of
Sublandlord against Subtenant’s interest in the Sublease or against the Building or the Site arising out of any work performed by Subtenant or any litigation in which Subtenant is a party or (ii) to the extent not requested by Subtenant
prior to May 1, 2007. Further, in no event shall Sublandlord be required to make application of any portion of the Subtenant Allowance on account of any supervisory fees, overhead, management fees or other payments to Subtenant, or any partner
or affiliate of Subtenant. 
 4. RENT AND OTHER CHARGES. 
 A. Fixed Rent. Subtenant shall pay Sublandlord without offset or deduction and without notice or demand therefor the Fixed Rent in the amount
specified in Section 1 of this Sublease. Subject to any applicable notice and cure period, Fixed Rent shall be payable monthly in advance on the first day of each month. Such monthly payments shall be in an amount equal to 1/12th of the amount
of Fixed Rent due per annum. 
 B. Additional Rent. Subtenant shall also pay Sublandlord, as additional rent (“Additional Rent”),
such other sums of money as shall become due and payable by Sublandlord to Landlord pursuant to the Prime Lease due to a default by Subtenant under this Sublease, within thirty (30) days of Subtenant’s receipt of an invoice thereof. If
Subtenant fails to pay any 
  

 3 

 rent when due, and such failure continues for ten (10) days after written notice from Sublandlord thereof, such
unpaid amount shall bear a five percent (5%) late charge, which will be immediately due and payable. Subtenant shall also pay Sublandlord, as Additional Rent, its “pro-rata share” of increases or escalations in operating expenses
above the “Operating Expenses Allocable to the Premises” as defined in the Prime Lease for calendar year 2006 and its “pro-rata share” of increases or escalations in real estate taxes above the “Landlord Tax Expenses
Allocable to the Premises” as defined in the Prime Lease for fiscal year 2007. For purposes of this Section 4.B., Subtenant’s “pro-rata share” shall be the percentage expressed as a fraction, the numerator of which is 51,291
s.f., and the denominator of which is the number of rentable square feet of floor area that Sublandlord is leasing under the Prime Lease (such number to include the rentable square feet of the Sublease Premises) as such rentable square feet may
change from time to time. By way of example only, if Sublandlord is leasing 63,500 rentable square feet of floor area under the Prime Lease (including the Sublease Premises), Subtenant’s “pro-rata share” would be 51,291/63,500
(80.77%). In addition to the Fixed Rent, Subtenant shall pay for its electricity for lights and outlets used within the Sublease Premises at the following rates: May 1, 2006-April 30, 2007, $61,549.20 per annum, in monthly instalments of
$5,129.10; May 1, 2007- April 30, 2008, $66,678.30 per annum, in monthly instalments of $5,556.53; May 1, 2008-April 30, 2009, $71,807.40 per annum, in monthly instalments of $5,983.95. In addition, on May 1, 2006 Subtenant
shall pay $1,880.67 to Sublandlord, representing electricity for lights and outlets used within the Sublease Premises from April 20, 2006 to April 30, 2006. Such monthly instalments shall be due on or before the first day of each month.

 C. Prorations. Fixed Rent and Additional Rent payable pursuant to Section 4 shall be prorated for any portion of a calendar
month included at the beginning or end of the term of this Sublease. 
 D. Delivery of Rent. Notwithstanding anything to the contrary
set forth in this Sublease, all payments by Subtenant of Fixed Rent, Additional Rent, payments of Subtenant’s Electricity, and any other charges, fees, interest or sums due Sublandlord under this Sublease shall be subject to the terms and
conditions of Section 5.6.5(C) of the Prime Lease, which terms are expressly incorporated herein by this reference. Sublandlord hereby agrees that all payments made directly to Landlord by Subtenant of Fixed Rent, Additional Rent, payments of
Subtenant’s Electricity, and any other charges, fees, interest or sums due Sublandlord under this Sublease in accordance with Section 5.6.5(C) of the Prime Lease shall be binding upon Sublandlord in the same manner as if Subtenant had
delivered such sums directly to Sublandlord as required hereunder. 
 E. Cafeteria. Subtenant shall have access to the food service
area (the “Cafeteria”) area, common to all tenants in the Building, located on the first floor of the Building. However, Subtenant shall solely have the responsibility of hiring and managing a third party to operate the Cafeteria, and
Subtenant shall be responsible for all costs, fees, liabilities and expenses in connection therewith. 
  

 4 

 5. USE. The Sublease Premises shall be used for the Permitted Uses and for no other purposes. 
 6. CONDITION OF PREMISES. Sublandlord shall deliver the Sublease Premises to Subtenant in “As-Is”, broom clean condition at the start of the Term.
Subtenant agrees to accept the Sublease Premises in “As-Is” condition and shall deliver the Sublease Premises in broom- clean condition. Subject to Section 3(C) and 3(D) above, all costs and expenses for Subtenant’s improvements
and cabling shall be borne by Subtenant and any installation and modifications must be approved in advance by Sublandlord, such approval not to be unreasonably withheld, conditioned or delayed. 
 7. ASSIGNMENT AND SUBLEASING. Subtenant shall not assign this Sublease nor sublet the Sublease Premises in whole or in part without complying with the terms of
the Prime Lease and without the prior consent of Sublandlord, which shall not be unreasonably withheld or delayed, and shall not permit Subtenant’s interest in this Sublease to be vested in any third party by operation of law or otherwise;
provided, however, that neither a corporate restructuring nor a public offering of Subtenant shall constitute an assignment hereof, but a change of control of Subtenant shall constitute an assignment hereof, unless the surviving party can reasonably
show that it is at least as creditworthy as Subtenant immediately prior to the change of control and the surviving party agrees to assume each and every right and obligation of Subtenant hereunder. 
 8. RELATION TO PRIME LEASE. This Sublease is subject and subordinate to the Prime Lease. Except as may be herein specifically provided in this Sublease or
Exhibit C, all the terms, covenants and conditions contained in the Prime Lease shall, with respect to the Sublease Premises, be applicable to this Sublease with the same force and effect as if Sublandlord were the landlord under the Prime
Lease and Subtenant were the tenant thereunder (except that Subtenant shall have no responsibility for any obligations (i) arising out of a default or breach by Sublandlord under the Prime Lease not arising out of Subtenant’s breach
hereunder, or (ii) pertaining to the Remaining Premises, which obligations shall remain the sole obligations of Sublandlord in all instances); and in case of any breach hereof by Subtenant, Sublandlord shall have all of the rights against
Subtenant as would be available to the landlord against the tenant under the Prime Lease as if such breach had occurred with respect to the tenant thereunder. 
 9. MAINTENANCE/SERVICES. With respect to the maintenance, repairs, replacements and/or services which Landlord is obligated to provide to Sublandlord under the Prime Lease, Sublandlord’s sole obligation to Subtenant shall be to
use its best efforts to require the Landlord to perform its obligations with respect thereto in accordance with the Prime Lease including, but not limited to, making demand upon Landlord to perform its obligations under the Prime Lease, including,
if necessary in Sublandlord’s reasonable discretion, taking appropriate legal action to enforce the Prime Lease, provided that Subtenant agrees to pay all reasonable costs and expenses of Sublandlord related to such legal action. Sublandlord
shall provide Subtenant with advance notice of any such action to enforce the terms of the Prime Lease (including its choice of attorney and an estimate of the costs and expenses likely to be incurred) and keep Subtenant reasonably informed of
material developments in any such legal proceedings. 
  

 5 

 10. COMPLIANCE WITH PRIME LEASE. Subtenant shall neither do nor permit anything to be done which would violate any
term or provision of the Prime Lease which is applicable to Subtenant, and Subtenant shall indemnify and hold Sublandlord harmless from and against all claims of any kind whatsoever by reason of any breach or default on the part of Subtenant of such
terms and provisions of the Prime Lease. Subtenant represents to Sublandlord that it has read and is familiar with the terms of the Prime Lease. 
 11.
SECURITY DEPOSIT. Upon execution of this Sublease, Subtenant shall deposit with Sublandlord the sum specified in Section 1 of this Sublease or provide a letter of credit in the same amount as referenced in the definition of the terms
“Security Deposit” as security for Subtenant’s faithful and timely performance of each and every one of Subtenant’s obligations hereunder; provided that in the event Subtenant initially deposits cash as a Security Deposit,
Subtenant shall have the right to substitute some or all of the cash Security Deposit in an acceptable letter of credit in the same amount and from an agreed upon financial institution. If Subtenant fails to pay Fixed Rent, Additional Rent, or other
charges when due under this Sublease or fails to perform any of its other obligations hereunder, Sublandlord at its sole election, after the lapse of any applicable cure period, if any (including, without limitation, the cure period set forth in
Section 7.1 (a)(i) of the Prime Lease), may use or apply all or any portion of this Security Deposit for the payment of any Fixed Rent, Additional Rent, or other amount’ then due hereunder and unpaid or for the payment of any other sum for
which Sublandlord may become obligated by reason of Subtenant’s default or breach, or for any loss or damage sustained by Sublandlord as a result of Subtenant’s default or breach. If Sublandlord so uses any portion of the Security Deposit,
Subtenant shall within ten (10) days after written demand by Sublandlord, restore the cash Security Deposit or the applicable face amount of the letter of credit, and Subtenant’s failure to do so shall constitute a default under this
Sublease. Sublandlord shall not be required to keep the Security Deposit separate from its general accounts and shall have no obligation or liability for payment of interest on the Security Deposit. Subtenant shall have no right to claim a set-off
or credit on account of the Security Deposit until all of its liabilities hereunder have been ascertained and satisfied in full. Within thirty (30) days after the Term has expired, or Subtenant has vacated the Sublease Premises, whichever shall
last occur, and provided Subtenant is not then in default of any of its obligations hereunder, the Security Deposit or so much thereof as has not theretofore been applied by Sublandlord, shall be returned to Subtenant or to the last assignee, if
any, of Subtenant’s interest. Subtenant acknowledges that Sublandlord will agree to accept a Letter of Credit in lieu of a cash deposit as an accommodation to Subtenant and Subtenant agrees that the Letter of Credit and all amounts drawn
thereunder shall be treated for all purposes under this Sublease as if a cash deposit had been tendered to Sublandlord upon the execution of this Sublease. 
 12. INDEMNIFICATIONS. Except due to any breach of the Prime Lease or this Sublease by Sublandlord and/or the negligence or willful misconduct of Sublandlord, its agents, contractors, employees, licensees or invitees, Subtenant shall
indemnify, defend, and hold harmless Sublandlord, its agents, representatives and employees from and against any and all liabilities (statutory or otherwise), claims, suits, demands, judgments, costs, interest, and 
  

 6 

 expense, including, but not limited to, attorney’s fees and disbursements, arising from any injury to, or death of,

of the Subtenant in or about the Sublease Premises, (iii) any condition of the Sublease Premises due to or resulting from any default by Subtenant in the performance of Subtenant’s obligations under this Sublease, including but not limited
to breach or default of the Prime Lease as set forth in Paragraph 10 above, or (iv) any act, omission, or negligence of Subtenant or its agents, contractors, employees, licensees, or invitees. 
 Except due to any breach of the Prime Lease or this Sublease by Subtenant and/or the negligence or willful misconduct of Subtenant, its agents,
contractors, employees, licensees or invitees, Sublandlord agrees to and hereby does indemnify and save Subtenant harmless against all claims for damages to persons or property, and all expenses incurred by Subtenant as a result thereof, including
reasonable attorneys’ fees and court costs, by reason of any default of Sublandlord under the Prime Lease or this Sublease. 
 13. BROKERS.
Sublandlord and Subtenant warrant and represent to the other that they have dealt with no real estate broker in connection with this Sublease other than the Brokers. Sublandlord agrees to pay to Brokers for negotiating this Sublease, a commission as
agreed to in a separate agreement. Subtenant covenants to pay, hold harmless and indemnify the Sublandlord fi from and against any and all cost, expense or liability for any compensation, commissions or charges claimed by any broker on behalf of the

orally or in any manner other than by an agreement in writing and signed by the patty against whom enforcement of the change or termination is sought.

with use of the Sublease Premises, the use of the Furniture. Sublandlord represents and warrants to Subtenant that Sublandlord owns all of the Furniture free and clear of any encumbrances and that Sublandlord has the right and authority to lease
said Furniture to Subtenant without the consent or approval of any third party.

 A. Subject to the provisions of this Section 19, Sublandlord agrees
that if at any time Sublandlord shall receive or obtain a bona fide written offer or commitment which Sublandlord wishes, in good faith, to accept (a “Third Party Offer”) to sublease all or any portion of the approximately 11,938 rentable
square feet of space on the first floor of the Building not’ included in Sublease Premises which has not been previously subleased to another subtenant (the “First Refusal Space”), then Sublandlord shall first give notice thereof to
Subtenant, provided that, as of the date Sublandlord receives such Third Party Offer, (i) there exists no “Event of Default” (as defined in the Prime Lease), (ii) this Sublease is still in full force and effect and
(iii) Subtenant has not sublet more than forty percent (40%) of the Sublease Premises in the aggregate. Said notice shall consist of a copy of the Third Party Offer and two counterpart originals of a commitment to enter into an amendment
to this Sublease to incorporate the space subject to the Third Party Offer into the Sublease Premises demised under this Sublease upon the terms and conditions of the Third Party Offer (herein called “Sublandlord’s Submitted Offer”),
provided that the First Refusal Space shall be added to the Sublease Premises under this Sublease in its “as-is” condition, and Sublandlord shall have no obligation to provide Subtenant with an allowance for design or construction of
improvements in the First Refusal Space or to install any improvements therein. Prior to sending such notice, Sublandlord shall use best efforts to keep Subtenant informed of possible Third Party Offers subject to this Section 19. 

B. Subtenant shall have the right to accept Sublandlord’s Submitted Offer by executing such two (2) counterpart original commitments to
enter into such lease amendment and delivering to Sublandlord the same within five (5) calendar days after its receipt of Sublandlord’s Submitted Offer. Within ten (10) business days after Sublandlord’s receipt of such accepted
commitment, Sublandlord shall deliver to Subtenant two (2) counterpart originals of an amendment to this Sublease to incorporate the space subject to the Third Party Offer into the Sublease Premises demised under this Sublease upon the terms
and conditions of such accepted commitment. Within five (5) business days after Subtenant’s receipt of such amendment Subtenant shall execute both counterpart originals of such amendment mad shall deliver the same to Sublandlord along with
appropriate evidence of the authority of Subtenant to 
  

 8 

 enter into the transaction. If Subtenant shall duly and timely comply with the foregoing, Sublandlord shall execute the
two (2) counterpart original amendments and shall promptly return one (1) fully executed counterpart to Subtenant. 
 C. If at the
expiration of five (5) calendar days after Subtenant’s receipt of Sublandlord’s Submitted Offer Subtenant shall not have accepted Sublandlord’s Submitted Offer by entering into such commitment and delivering the same to
Sublandlord, or if Subtenant shall so execute and deliver such commitment, but at the end of five (5) business days after Subtenant’s receipt of such lease amendment Subtenant has not entered into such lease amendment and delivered the
same to Sublandlord and/or has not complied with the provisions of subparagraph (B) above, time being of the essence in respect to all of the same, Sublandlord shall be free to sublease the First Refusal Space subject to the Third Party Offer
upon terms no less favorable to the Sublandlord than contained in Sublandlord’s Submitted Offer without again offering such space to Subtenant for sublease; provided, however, that in the event (i) such Third Party Offer does not result in
a definitive sublease of the First Refusal Space subject to the Third Party Offer to the party malting the Third Party Offer; or (ii) the Third Party Offer is amended (by either the Third Papacy or Sublandlord) such that the Fixed Rent of the
First Refusal Space is at least Fifteen Percent (15%) lower than originally presented in the Third Party Offer, such First Refusal Space shall remain subject to the terms of this Section 19. 
 20. CONSENT OF LANDLORD. This Sublease is contingent upon, and shall not be effective until, Sublandlord obtains, at its sole cost and expense, the written
consent of the Landlord to this Sublease as provided under the terms of the Prime Lease within 30 days of the date hereof; provided, however, that any delay in the receipt of the consent of the Landlord as a result of the actions of Subtenant, its
employees or its legal counsel or its agents will not be taken into account for purposes of calculating the said 30 day period. All costs of obtaining such consent shall be borne by Sublandlord.

to lease such space on such terms within three (3) business days after Landlord’s notice to Tenant of the availability of such space and of. such terms. If Tenant shall give such notice, the same shall constitute an agreement to enter into
an amendment to this Lease to incorporate such space into the Premises upon the terms set forth in Landlord’s notice. If Tenant shall not so exercise such right within such period, time being of the essence in respect of such exercise, Landlord
shall be free at any. time thereafter to enter into a lease of such space with another prospective tenant upon terms no less favorable to Landlord than those set forth in Landlord’s notice to Tenant, provided that Landlord shall reoffer such

occupant of such premises to so vacate shall not give Tenant any right to terminate this Lease or to deduct from, offset against or withhold Annual Fixed Rent, additional rent or other charges due under this Lease (or any portions thereof).

 (D) If Tenant shall lease additional space in the Building pursuant to this Section 2.1.2, Tenant’s parking rights under this

 (ii) Effective as of the date when Landlord delivers possession of the Expansion space, or portions thereof, to Tenant, the Expansion Space, or such portions thereof, shall become a part of the Premises demised under this Lease for the
balance of the Term of this Lease, as it may be extended; and 
 (iii) The Annual Fixed Rent attributable to the Expansion Space and payments
on account of real estate taxes, operating costs and electricity for any remaining portion of the original Lease Term and any Extended Term respecting the Expansion Space shall be as determined in accordance with the provisions of this

 -16- 

 forty-eighth (48th) calendar month of. the Lease Term (not including any partial month after the
Commencement Date) of Tenant’s exercise of its option to Lease the Expansion space.

and shall include a floor plan showing the location of the Expansion Space (collectively “Landlord’s Expansion Proposal”). 
 (E) If at the-expiration of thirty (30) days after the date when Tenant receives Landlord’s Expansion Proposal (the “Negotiation Period”), Landlord and Tenant have not reached agreement on a determination of an annual
rental and all other relevant terms for the Expansion Space and execute a written instrument pursuant to such agreement adding the Expansion Space to the Premises, then either Landlord or Tenant shall have the right, by notice given to the other
party within fifteen (15) days following the expiration of the Negotiation Period, to request a broker determination (the “Broker Determination”) of the Prevailing Market Rent (as defined in Exhibit G) for the Expansion Space, which
Broker Determination shall be made in the manner set forth in Exhibit G. If neither Landlord nor Tenant shall so request a broker determination, the Annual Fixed Rent for the Expansion Space shall be as set forth in Landlord’s Expansion

Complete the Premises Tenant shall have the right to terminate this Lease by giving notice to Landlord of Tenant’s desire so to do; and, upon the giving of such notice, the Term of this Lease shall cease and come to an end without further
liability or obligation on the part of either party unless, within thirty (30) days after Landlord’s receipt of Tenant’s notice Landlord substantially completes the work to be performed by Landlord under Section 3.1 (except for
punch list items and long lead items) and such right of termination shall be Tenant’s sole and exclusive remedy at law or in equity or otherwise for Landlord’s failure so to complete such work within such time. 
  

 -31- 

 Tenant agrees that no delay by it, or anyone employed by it, in performing work to prepare the Premises
for occupancy (including, without limitation, the work in installing telephones and other communications equipment or systems) shall delay commencement of the Term or the obligation to pay rent.

structural or exterior element of the Building, any area or element outside of the Premises, or any facility serving any area of the Building outside of the Premises, or (b) will delay completion of the Premises or Building, or (c) will
require unusual expense to readapt the Premises to normal office use on Lease termination or increase the cost of construction or of insurance or taxes on the Building or of the services called for by Section 4.1 unless Tenant first gives
assurance acceptable to Landlord for payment Of such increased cost and that such readaptation will be made prior to such termination without expense to Landlord. All alterations and additions shall be part of the Building unless and until Landlord
shall specify the same for removal pursuant to Section 5.2. All of Tenant’s alterations and additions and installation of furnishings shall be coordinated with any work being performed by Landlord and in such manner as to maintain
harmonious labor relations and not to damage the Buildings or Site or interfere with construction or operation of the Buildings and other improvements to the Site and, except for installation of furnishings, shall be performed by Landlord’s
general contractor or by contractors or workmen first approved by Landlord. Except for work by Landlord’s general contractor, Tenant, before its work is started, shall secure all licenses and permits necessary therefor; deliver to Landlord a

 additional insured and insuring Tenant as well as the contractors), and to deliver to Landlord
certificates of all such insurance. Tenant agrees to pay promptly when due the entire cost of any work done on the Premises by Tenant, its agents, employees, or independent contractors, and not to cause or permit any liens for labor or materials
performed or furnished in connection therewith to attach to the Premises or the Buildings or the Site and immediately to discharge any such liens which may so attach. Tenant shall pay, as additional rent, 100% of any real estate taxes on the Complex
which shall, at any time after commencement of the Term, result from any alteration, addition or improvement to the Premises made by Tenant.

with design and construction upon approval and other actions on the party’s behalf by any Construction Representative of the party named in Article I or any person hereafter designated in substitution or addition by notice to the party relying.
Except as otherwise provided in Article IV, the work required of Landlord pursuant to this Article III shall be deemed approved by Tenant when Tenant commences occupancy of the Premises for the Permitted Uses, except for items which are then
uncompleted (including punch list items and long lead items) and as to which Tenant shall have given notice to Landlord prior to such date.

Tenant’s interest in this Lease or sublet (which term, without limitation, shall include granting of concessions, licenses or the like) the whole or any part of the Premises. Any assignment, mortgage, pledge, hypothecation,

  

 -36- 

 transfer or subletting not expressly permitted in or consented to by Landlord under Sections 5.6.1-5.6.5
shall be void, ab initio; shall be of no force and effect; and shall confer no rights on or in favor of third parties. In addition, Landlord shall be entitled to seek specific performance of or other equitable relief with respect to the provisions
hereof. 
  

	5.6.1	Notwithstanding the provisions of Section 5.6 above and the provisions of Section 5.6.3 and 5.6.4 below, Tenant shall have the right to assign this Lease or to sublet the
Premises (in whole or in part) to any parent or subsidiary corporation of Tenant or to any corporation into which Tenant may be converted or with which it may merge, or to any affiliated entity controlling, controlled by or under common control with

pursuant to Section 5.6.1, such information as to the proposed assignee’s or proposed subtenant’s net worth and financial capability and standing as may reasonably be required for Landlord to make the determination referred to in
Section 5.6.3 below (provided, however, that Landlord shall hold such information confidential having the right to release same to its officers, accountants, attorneys and mortgage lenders on a confidential basis), (c) all of the terms-and

to in Section 5.6.3 below. If Landlord shall consent to the proposed assignment or subletting or in the case of a proposed assignment of subletting pursuant to Section 5.6.1 Landlord shall determine that the proposed assignment or
subletting complies with the requirements of Section 5.6.1, as the case may be, then, in such event, Tenant may thereafter sublease or assign pursuant to Tenant’s notice, as given hereunder; provided, however, that if such assignment or
sublease shall not be executed and delivered to Landlord within one hundred-twenty (120) days after the date of 

  

 -37- 

 Landlord’s consent, the consent shall be deemed null and void and the provisions of Sections
5.6.2-5.6.5 shall be applicable. 
  

	5.6.3	Notwithstanding the provisions of Section 5.6 above, but subject to the provisions of this Section 5.6.3 and the provisions of Sections 5.6.4 and 5.6.5 for a period of one
hundred twenty (120) days after the receipt of Tenant’s notice referred to in Section 5.6.2, Tenant shall have the right to assign this Lease or sublet the Premises in accordance with Tenant’s notice to Landlord given as provided
in Section 5.6.2 provided that, in each instance, Tenant first obtains the express prior written consent of Landlord, which consent shall not be unreasonably withheld or delayed. Landlord shall not be deemed to be unreasonably withholding its
consent to such a proposed assignment or subleasing if: 

  

	 	(a)	the operations of the proposed assignee or subtenant are not consistent with the operation of a first class office building (by way of example Landlord shall not be deemed to be
unreasonably withholding its consent to an assignment or subleasing, to any governmental agency), or 

  

	 	(b)	the proposed assignee or subtenant does not possess adequate financial capability to perform the Tenant obligations as and when due or required, or

	 	(e)	in the case of a proposed subletting, the proposed location of the subtenant’s premises would negatively impact the Building management or the configuration of the remainder of
the Premises or the Building. 

  

	5.6.4	In addition, in the case of any assignment or subleasing as to which Landlord may consent (other than an assignment or subletting permitted under Section 5.6.1 hereof) such
consent shall be upon the express and further condition, covenant and agreement, and Tenant hereby covenants and agrees that, in addition to the Annual Fixed Rent, additional rent and other charges to be paid pursuant to this Lease, fifty percent
(50%) of the “Assignment/Sublease Profits” (hereinafter defined), if any, shall be paid to Landlord. 

  

 -38- 

 The “Assignment/Sublease Profits” shall be the excess, if any, of (a) the
“Assignment/Sublease Net Revenues” as hereinafter defined over. (b) the Annual Fixed Rent and additional rent and other charges provided in this Lease. The “Assignment/Sublease Net Revenues” shall be the fixed rent, additional
rent and all other charges and sums payable either initially or over the term of the sublease or assignment plus all other profits and increases to be derived by Tenant as a result of such subletting or assignment less the reasonable costs of Tenant
incurred in such subleasing or assignment (the definition of which shall include but not necessarily be limited to rent concessions, brokerage commissions and alteration allowances). 
 All payments of the Assignment/Sublease Profits due Landlord shall be made within thirty (30) days of receipt of same by Tenant. 
  

	5.6.5	(A) It shall be a condition of the validity of any assignment or subletting of right under Section 5.6.1 above, or consented to under Section 5.6.3 above, that the
assignee or sublessee agrees directly with Landlord, in form reasonably satisfactory to Landlord, to be bound by all the obligations of the Tenant hereunder, including, without limitation, the obligation to pay the rent and other amounts provided
for under this Lease (but in the case of a partial subletting, such subtenant shall agree on a pro rata basis to be so bound) including the provisions of Sections 5.6 through 5.6.5 hereof, but such assignment or subletting shall not relieve the
Tenant named herein of any of the obligations of the Tenant hereunder, and Tenant shall remain fully and primarily liable thereof. 

 (B) As additional rent, Tenant shall reimburse Landlord promptly for reasonable out of pocket legal and other expenses incurred by Landlord in connection with any request by Tenant for consent to assignment or subletting. 
 (C) If this Lease be assigned, or if the Premises or any part thereof be sublet or occupied by anyone other than Tenant, Landlord may upon prior notice to
Tenant, at any time and from time to time, collect rent and other charges from the assignee, sublessee or occupant and apply the net amount collected to the rent and other charges herein reserved and Tenant shall have no obligation to make payment
for such amount collected, but no such assignment, subletting, occupancy or collection shall be deemed a waiver of this covenant, or a waiver of the provisions of Sections 5.6 through 5.6.5 hereof, or of the obligation to payment for other or future
amounts due under this Lease, 
  

 -39- 

 or the acceptance of the assignee, sublessee or occupant as a tenant or a release of Tenant from the
further performance by Tenant of covenants on the part of Tenant herein contained, the Tenant herein named to remain primarily liable under this Lease. 
 (D) The consent by Landlord to an assignment or subletting under Section 5.6.3 shall in no way be construed to relieve Tenant from obtaining the express consent in writing to Landlord to any further assignment or
subletting. 
  

	5.7	To defend with counsel first approved by Landlord (which approval shall not be unreasonably withheld or delayed), save harmless, and indemnify Landlord from any liability for
injury, loss, accident or damage to any person or property, and from any claims, actions, proceedings and expenses and costs in connection therewith (including without limitation reasonable counsel fees) (i) arising from (a) the omission,
fault, willful act, negligence or other misconduct of Tenant or (b) from any use made or thing done or occurring on the Premises not due to the omission, fault, willful act, negligence or other misconduct of Landlord, or (ii) resulting

comprehensive general liability insurance with a broad form comprehensive liability endorsement covering the Premises insuring Landlord (as an additional insured) as well as Tenant with limits which shall, at the commencement of the Term, be at
least equal to those stated in Section 1.1 and from time to time during the Term shall be for such higher limits, if any, as are customarily carried in Greater Boston with respect to similar properties or which may reasonably be required by
Landlord, and workmen’s compensation insurance with statutory limits covering all of Tenant’s employees working in the Premises, and to deposit with Landlord on or before the Commencement Date and concurrent with all renewals thereof,
certificates for such insurance bearing the endorsement that the policies will not be cancelled until after thirty (30) days’ written notice to Landlord. 

  

	5.8	That all of the furnishings, fixtures, equipment, effects and property of every kind, nature and description of Tenant and of all persons claiming by, through or under Tenant which,
during the continuance of this Lease or any occupancy of the Premises by Tenant or anyone claiming under Tenant, may be on the Premises or elsewhere in the Building or on the Site, shall be at the sole risk and hazard of Tenant, and if the whole or
any part thereof shall be destroyed or damaged by fire, water or otherwise, or by the leakage or bursting of water pipes, or other 

  

 -40- 

 pipes, by theft or from any other cause, no part of said loss or damage is to be charged to or be borne
by Landlord, provided that this limitation shall not apply to damage to the extent caused by Landlord’s negligence, and provided further that Landlord shall in no event be indemnified or held harmless or exonerated from any liability to Tenant
or to any other person, for any injury, loss, damage or liability to the extent such indemnity, hold harmless or exoneration is prohibited by law. 
  

	5.9	To permit Landlord and its agents to examine the Premises at reasonable times and, if Landlord shall so elect, to make any repairs or replacements Landlord may deem necessary; to
remove, at Tenant’s expense, any alterations, addition, Signs, curtains, blinds, shades, awnings, aerials, flagpoles, or the like not consented to in writing; and to show the Premises to prospective tenants during the nine (9) months

vibration or noise that may be transmitted to the Building structure or to any other space in the Building shall be so installed, maintained and used by Tenant so as to eliminate such vibration or noise. 

  

	5.11	To pay promptly when due all taxes which may be imposed upon personal property (including, without limitation, fixtures and equipment) in the Premises to whomever assessed. 

 ARTICLE VI 
 CASUALTY AND TAKING  
  

	6.1	In case during the Lease Term the Building or the Site are damaged by fire or other casualty and such fire or casualty damage cannot, in the ordinary course, reasonably be expected
to be repaired within one hundred fifty (150) days from the time that repair work would commence, Landlord or Tenant may, at either party’s election, terminate this Lease by notice given to the other party within sixty (60) days after
the date of such fire or other casualty, specifying the effective date of termination. The effective date of termination specified by such notice shall not be less than thirty (30) days nor more than forty-five (45) days after the date of
notice of such termination. 

  

 -41- 

 Unless terminated pursuant to the foregoing provision, this Lease shall remain in full force and effect
following any such damage subject, however, to the following provisions. If the Building or the Site or any part thereof are damaged by fire or other casualty and this Lease is not so terminated, or Landlord or Tenant have no right to terminate this
Lease, and in any such case the holder of any mortgage which includes the Building as a part of the mortgaged premises or any ground lessor of any ground lease which includes the Site as part of the demised premises allows the net insurance proceeds
to be applied to the restoration of the Building (and/or the Site), Landlord shall, promptly after such damage and the determination of the net amount of insurance proceeds available use due diligence to restore the Premises and the Building in the
event of damage thereto (excluding any furniture, fixtures or equipment of Tenant, or any other items installed, or paid for, by Tenant) into proper condition for use and occupation and a just proportion of the Annual Fixed Rent, Tenant’s share
of Operating Costs and Tenant’s share of real estate taxes shall be abated according to the nature and extent of the injury to the Premises, until the Premises shall have been restored by Landlord substantially into such condition except for
punch list items and long lead items. Notwithstanding anything herein contained to the contrary, Landlord shall not be obligated to expend for such repair and restoration any amount in excess of the net insurance proceeds. 
  

	6.2	Notwithstanding anything to the contrary contained in this Lease, if the Building or the Premises shall be substantially damaged by fire or casualty as the result of a risk not
covered by the forms of casualty insurance at the time maintained by Landlord and such fire or casualty damage cannot, in the ordinary course, reasonably be expected to be repaired within ninety (90) days from the time that repair work would
commence, Landlord or Tenant may, at either party’s election, terminate the Term of this Lease by notice to the other party given within thirty (30) days after such loss. If either party shall give such notice, then this Lease shall
terminate as of the date of such notice with the same force and effect as if such date were the date originally established as the expiration date hereof. 

  

	6.3	If the entire Building, or such portion of the Premises as to render the balance (if reconstructed to the maximum extent practicable in the circumstances) unsuitable for
Tenant’s purposes, shall be taken by condemnation or right of eminent domain, Landlord or Tenant shall have the right 

  

 -42- 

 to terminate this Lease by notice to the other of its desire to do so, provided that such notice is given
not later than thirty (30) days after Tenant has been deprived of possession. If either party shall give such notice, then this Lease shall terminate as of the date of such notice with the same force and effect as if such date were the date
originally established as the expiration date hereof. 
 Further, if so much of the Building shall be so taken that continued operation of the
Building would be uneconomic as a result of the taking, Landlord shall have the right to terminate this Lease by giving notice to Tenant of Landlord’s desire to do so not later than thirty (30) days after Tenant has been deprived of
possession of the Premises (or such portion thereof as may be taken). If Landlord shall give such notice, then this Lease shall terminate as of the date of such notice with the same force and effect as if such date were the date originally
established as the expiration date hereof. Should any part of the Premises be so taken or condemned during the Lease Term hereof, and should this Lease not be terminated in accordance with the foregoing provisions, and the holder of any mortgage
which includes the Premises as part of the mortgaged premises or any ground lessor of any ground lease which includes the Site as part of the demised premises allows the net condemnation proceeds to be applied to the restoration of the Building,
Landlord agrees, after the determination of the net amount of condemnation proceeds available to Landlord, to use due diligence to put what may remain of the Premises into proper condition for use and occupation as nearly like the condition of the
Premises prior to such taking as shall be practicable (excluding any furniture, fixtures or equipment of Tenant, or any other items installed or paid for by Tenant). Notwithstanding the foregoing, Landlord shall not be obligated to expend for such
repair and restoration any amount in excess of the net condemnation proceeds. If the Premises shall be affected by any exercise of the power of eminent domain, then the Annual Fixed Rent, Tenant’s share of Operating Costs and Tenant’s
share of real estate taxes shall be justly and equitably abated and reduced according to the nature and extent of the loss of use thereof suffered by Tenant; and in case of a taking which permanently reduces the Rentable Floor Area of the Premises,
a just proportion of the Annual Fixed Rent, Tenant’s share of Operating Costs and Tenant’s share of real estate taxes shall be abated for the remainder of the Lease Term. 
  

	6.4	Landlord shall have and hereby reserves to itself any and all rights to receive awards made for damages to the 

  

 -43- 

 Premises, the Building, the Complex and the Site and the leasehold hereby created, or any one or more of
them, accruing by reason of exercise of eminent domain or by reason of anything lawfully done in pursuance of public or other authority. Except as provided in the next paragraph, Tenant hereby grants, releases and assigns to Landlord all
Tenant’s rights to such awards, and covenants to execute and deliver such further assignments and assurances thereof as Landlord may from time to time request. 
 Subject to the rights of any mortgagee of the Building, the Site or the Complex, nothing contained herein shall be construed to prevent Tenant from prosecuting in any condemnation proceeding a claim for the value of
any of Tenant’s usual trade fixtures installed in the Premises by Tenant at Tenant’s expense and for relocation and moving expenses.  
 ARTICLE VII 
 DEFAULT 
  

	7.1	(a) If at any time subsequent to the date of this Lease any one or more of the following events (herein sometimes called an “Event of Default”) shall occur:

  

	 	(i)	Tenant shall fail to pay the fixed rent, additional rent or other charges for which provision is made herein on or before the date on which the same become due and payable, and the
same continues for seven (7) days after notice from Landlord thereof, or 

  

	 	(ii)	Landlord having rightfully given the notice specified in subdivision (a) above three (3) times in any calendar year, Tenant shall thereafter in the same calendar year fail
to pay the fixed rent, additional rent or other charges on or before the date on which the same become due and payable, or, 

  

	 	(iii)	Tenant shall neglect or fail to perform or observe any other covenant herein contained on Tenant’s part to be performed or observed and Tenant shall fail to remedy the same
within thirty (30) days after notice to Tenant specifying such neglect or failure, or if such failure is of such a nature that Tenant cannot reasonably remedy the same within such thirty (30) day period, Tenant shall fail to commence
promptly to remedy the same and to prosecute such remedy to completion with diligence and continuity; or 

  

 -44- 

	 	(iv)	Tenant’s leasehold interest in the Premises shall be taken on execution or by other process of law directed against Tenant; or 

  

	 	(v)	Tenant shall make an assignment for the benefit of creditors or shall file a voluntary petition in bankruptcy or shall be adjudicated bankrupt or insolvent, or shall file any
petition or answer seeking any reorganization, arrangement, composition, readjustment, liquidation, dissolution or similar relief for itself under any present or future Federal, State or other statute, law or regulation for the relief of debtors, or
shall seek or consent to or acquiesce in the appointment of any trustee, receiver or liquidator of Tenant or of all or any substantial part of its properties, or shall admit in writing its inability to pay its debts generally as they become due; or

  

	 	(vi)	A petition shall be filed against Tenant in bankruptcy or under any other law seeking any reorganization, arrangement, composition, readjustment, liquidation, dissolution, or
similar relief under any present or future Federal, State or other statute, law or regulation and shall remain undismissed or unstayed for an aggregate of sixty (60) days (whether or not consecutive), or if any debtor in possession (whether or
not Tenant) trustee, receiver or liquidator of Tenant or of all or any substantial part of its properties or of the Premises shall be appointed without the consent or acquiescence of Tenant and such appointment shall remain unvacated or unstayed for
an aggregate of sixty (60) days (whether or not consecutive)— 

 then, and in any of said cases (notwithstanding any
license of a former breach of covenant or waiver of the benefit hereof or consent in a former instance), Landlord lawfully may, immediately or at any time thereafter, and without demand or further notice terminate this Lease by notice to Tenant,
specifying a date not less than ten (10) days after the giving of such notice on which this Lease shall terminate, and this Lease shall come to an end on the date specified therein as fully and completely as if such date were the date herein
originally fixed for the expiration of the Lease Term (Tenant hereby waiving any rights of redemption), and Tenant will then quit and surrender the Premises to Landlord, but Tenant shall remain liable as hereinafter provided. 
  

 -45- 

 (b) If this Lease shall have been terminated as provided in this Article, then Landlord may, re-enter the
Premises pursuant to summary proceedings instituted in accordance with applicable laws or an agreement with Tenant (provided that no such proceedings or agreement shall be required for such entry if Tenant shall vacate or abandon the Premises), and
remove and dispossess Tenant and all other persons and any and all property from the same, as if this Lease had not been made 
 (c) In the
event that this Lease is terminated under any of the provisions contained in Section 7.1 (a) or shall be otherwise terminated by breach of any obligation of Tenant, Tenant covenants and agrees forthwith to pay and be liable for, on the
days originally fixed herein for the payment thereof, amounts equal to .the several installments of rent and other charges reserved as they would, under the terms of this Lease, become due if this Lease had not been terminated or if Landlord had not
entered or re-entered, as aforesaid, and whether the Premises be relet or remain vacant, in whole or in part, or relet for a period less than the remainder of the Term, and for the whole thereof, but in the event the Premises be relet by Landlord,
Tenant shall be entitled to a credit in the net amount of rent and other charges received by Landlord in reletting, after deduction of all reasonable expenses incurred in reletting the Premises (including, without limitation, remodeling costs,
brokerage fees and the like), and in collecting the rent in connection therewith, in the following manner: Amounts received by Landlord after reletting shall first be applied against such Landlord’s reasonable expenses, until the same are
recovered, and until such recovery, Tenant shall pay, as of each day when a payment would fall due under this Lease, the amount which Tenant is obligated to pay under the terms of this Lease (Tenant’s liability prior to any such reletting and
such recovery not in any way to be diminished as a result of the fact that such reletting might be for a rent higher than the rent provided for in this Lease); when and if such expenses have been completely recovered, the amounts received from
reletting by Landlord as have not previously been applied shall be credited against Tenant’s obligations as of each day when a payment would fall due under this Lease, and only the net amount thereof shall be payable by Tenant. Further, amounts
received by Landlord from such reletting for any period shall be credited only against obligations of Tenant allocable to such period, and shall not be credited against obligations of Tenant hereunder accruing subsequent or prior to such period; nor
shall any credit of any kind be due for any period after the date when the term of this Lease is scheduled to expire according to its terms. 
  

 -46- 

 (d) (i) At any time after such termination and whether or not Landlord shall have collected any
damages as aforesaid, Tenant shall pay to Landlord as liquidated final damages And in lieu of all other damages beyond the date of notice from Landlord to Tenant, at Landlord’s election, such a sum as at the time of the giving of such notice
represents the amount of the excess, if any, of the total rent and other benefits which would have accrued to Landlord under this Lease from the date of such notice for what would be the then unexpired Lease Term if the Lease terms had been fully
complied with by Tenant over and above the then cash rental value (in advance) of the Premises for the balance of the Lease Term. 
 (d)
(ii) For the purposes of this Article, if Landlord elects to require Tenant to pay damages in accordance with the immediately preceding paragraph, the total rent shall be computed by assuming that Tenant’s share of excess taxes,
Tenant’s share of excess operating costs and Tenant’s share of excess electrical costs would be, for the balance of the unexpired Term from the date of such notice, the amount thereof (if any) for the immediately preceding annual period
payable by Tenant to Landlord. 
 (e) In case of any Event of Default, and Tenant shall be dispossessed by summary proceedings or pursuant to
or an agreement with Landlord or Tenant shall vacate or abandon the Premises, Landlord may (i) re-let the Premises or any part or parts thereof, either in the name of Landlord or otherwise, for a term or terms which may at Landlord’s
option be equal to or less than or exceed the period which would otherwise have constituted the balance of the Term of this Lease and may grant concessions or free rent to the extent that Landlord considers reasonably advisable or necessary to
re-let the same and (ii) may make such alterations, repairs and decorations in the Premises as Landlord in its sole judgment considers advisable or necessary for the purpose of reletting the Premises; and the making of such alterations, repairs
and decorations shall not operate or be construed to release Tenant from liability hereunder as aforesaid. Tenant hereby expressly waives any and all rights of redemption granted by or under any present or future laws in the event of Tenant being
evicted or dispossessed in accordance with the provisions of this Lease, or in the event of Landlord obtaining possession of the Premises in accordance with the provisions of this Lease, by reason of the violation by Tenant of any of the covenants
and conditions of this Lease. 
 (f) The specified remedies to which Landlord may resort hereunder are not intended to be exclusive of any
remedies or means of redress to which Landlord may at any time be entitled lawfully, and Landlord may invoke any remedy 
  

 -47- 

 allowed at law or in equity as if specific remedies were not herein provided for. Further, nothing
contained in this Lease shall limit or prejudice the right of Landlord to prove and obtain in proceedings for bankruptcy or insolvency by reason of the termination of this Lease, an amount equal to the maximum allowed by any statute or rule of law
in effect at the time when, and governing the proceedings in which, the damages are to be proved, whether or not the amount be greater, equal to, or less than the amount of the loss or damages referred to above. 
  

	7.2	Landlord shall in no event be in default in the performance of any of Landlord’s obligations hereunder unless and until Landlord shall have failed to perform such obligations
within thirty (30) days, or such additional time as is reasonably required to correct any such default, after notice by Tenant to Landlord properly specifying wherein Landlord has failed to perform any such obligation. 

 ARTICLE VIII  
  

	8.1	Tenant covenants and agrees that Tenant will not do or permit anything to be done in or upon the Premises, or bring in anything or keep anything therein, which shall invalidate or
increase the rate of insurance on the Premises or on the Building above the Standard rate applicable to premises being occupied for the use to which Tenant has agreed to devote the Premises; and Tenant further agrees that, in the event that Tenant
shall do any of the foregoing, Tenant will promptly pay to Landlord, on demand, any such increase resulting therefrom, which shall be due and payable as additional rent thereunder. 

  

	8.2	Failure on the part of Landlord or Tenant to complain of any action or non-action on the part of the other, no matter how long the same may continue, shall never be a waiver by
Tenant or Landlord, respectively, of any of the other’s rights hereunder. Further, no waiver at any time of any of the provisions hereof by Landlord or Tenant shall be construed as a waiver of any of the other provisions hereof, and a waiver at
any time of any of the provisions hereof shall not be construed as a waiver at any subsequent time of the same provisions. The consent or approval of Landlord or Tenant to or of any action by the other requiring such consent or approval shall not be
construed to waive or render unnecessary Landlord’s or Tenant’s consent or approval to or of subsequent similar act by the other. 

 No payment by Tenant, or acceptance by Landlord, of a lesser amount than shall be due from Tenant to Landlord shall be treated otherwise than as a payment on account. The acceptance by Landlord of a check for a lesser
amount 
  

 -48- 

 with an endorsement or statement thereon, or upon any letter accompanying such check, that such lesser
amount is payment in full,, shall be given no effect, and Landlord may accept such check without prejudice to any other rights or remedies which Landlord may have against Tenant. 
  

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

  

	8.4	Tenant, subject to the terms and provisions of this Lease on payment of the rent and observing, keeping and performing, all of the terms and provisions of this Lease on
Tenant’s part to be observed, kept and performed, shall lawfully, peaceably and quietly have, hold, occupy and enjoy the Premises during the Term subject to the terms of this Lease, without hindrance or ejection by any persons lawfully claiming
under Landlord to have title to the Premises superior to Tenant or without, hindrance or ejection due to Landlord’s failure to comply with the terms of this Lease; the foregoing covenant of quiet enjoyment is in lieu of any other covenant,
express or implied; and it is understood and agreed that this covenant and any and all other covenants of Landlord contained in this Lease shall be binding upon Landlord and Landlord’s successors only with respect to breaches occurring during
Landlord’s or Landlord’s successors’ respective ownership of Landlord’s interest hereunder, as the case may be. 

 Further, Tenant specifically agrees to look solely to Landlord’s then equity interest in the Building at the time owned, or in which Landlord holds an interest as ground lessee, for recovery of any judgment from Landlord; it being
specifically agreed that neither Landlord (original or successor), nor any partner in or of Landlord, nor any beneficiary of any Trust of which any person holding Landlord’s interest is Trustee, shall ever be personally liable for any such
judgment, or for the payment of any monetary obligation-to Tenant. The provision contained in the foregoing sentence is not intended to, and shall not, limit any right that Tenant might otherwise have to obtain injunctive relief against Landlord or
Landlord’s successors in interest, or any action not involving the personal liability of Landlord (original or successor), any partner in or of Landlord, any successor Trustee to the persons 
  

 -49- 

 named herein as Landlord, or any beneficiary of any Trust of which any person holding Landlord’s
interest is Trustee, to respond in monetary damages from Landlord’s assets other than Landlord’s equity interest aforesaid in the Building. In no event shall Landlord ever be liable to Tenant for any indirect or consequential damages
suffered by Tenant from whatever cause. 
  

	8.5	After receiving notice from any person, firm or other entity that it holds a mortgage which includes the Premises as part of the mortgaged premises, or that it is the ground lessor
under a lease with Landlord, as ground lessee, which includes the Premises as a part of the demised premises, no notice from Tenant to Landlord shall be effective unless and until a copy of the same is given to such holder or ground lessor, and the
curing of any of Landlord’s defaults by such holder or ground lessor within a reasonable time thereafter (including a reasonable time to obtain possession of the premises if the mortgagee or ground lessor elects to do so) shall be treated as
performance by Landlord. For the purposes of this Section 8.5 or Section 8.15, the term “mortgage” includes a mortgage on a leasehold interest of Landlord (but not One on Tenant’s leasehold interest). 

  

	8.6	With reference to any assignment by Landlord or Landlord’s interest in this Lease, or the rents payable hereunder, conditional in nature or otherwise, which assignment is made
to the holder of a mortgage or ground lease on property which includes the Premises, Tenant agrees: 

  

	 	(a)	That the execution thereof by Landlord, and the acceptance thereof by the holder of such mortgage or the ground lessor, shall never be treated as an assumption by such holder or
ground lessor of any of the obligations of Landlord hereunder, unless such holder, or ground lessor, shall, by notice sent to Tenant, specifically otherwise elect; and 

  

	 	(b)	That, except as aforesaid, such holder or ground lessor shall be treated as having assumed Landlord’s obligations hereunder only upon foreclosure of such holder’s mortgage
and the taking of possession of the Premises, or, in the case of a ground lessor, the assumption of Landlord’s position hereunder by such ground lessor. 

 In no event shall the acquisition of title to the. Building and the land on which the same is located by a purchaser which, simultaneously therewith,
leases the entire Building or such land back to the seller thereof be treated as an 
  

 -50- 

 assumption by such purchaser-lessor, by operation of law or otherwise, of Landlord’s obligations
hereunder, but Tenant shall look solely to such seller-lessee, -and its successors from time to time in title, for performance of Landlord’s obligations hereunder subject to the provisions of Section 8.4 hereof. In any such event, this
Lease shall be subject and subordinate to the lease to such purchaser provided that such purchaser agrees to recognize the right of Tenant to use and occupy the Premises upon the payment of rent and other charges payable by Tenant under this Lease
and the performance by Tenant of Tenant’s obligations under this Lease and provided that Tenant agrees to attorn to such purchaser. For all purposes, such seller-lessee, and its successors in title, shall be the landlord hereunder unless and
until Landlord’s position shall have been assumed by such purchaser-lessor. 
  

	8.7	No act or thing done by Landlord during the Lease Term shall be deemed an acceptance of a surrender of the Premises, and no agreement to accept such surrender shall be valid, unless
in writing signed by Landlord. No employee of Landlord or of Landlord’s agents shall have any power to accept the keys of the Premises prior to the termination of this Lease. The delivery of keys to any employee of Landlord or of
Landlord’s agents shall not operate as a termination of the Lease or a surrender of the Premises. 

  

	8.8	(A) Tenant warrants and represents that Tenant has not dealt with any broker in connection with the consummation of this Lease Other than the broker, person or firm, if any,
designated in Section 1.1 hereof, and in the event any claim is made against the Landlord-relative to dealings by Tenant with brokers other than the Brokers, if any, designated in Section 1.1 hereof, Tenant shall defend the claim against
Landlord with counsel of Tenant’s selection first approved by Landlord (which approval will not be unreasonably withheld or delayed) and save harmless and indemnify Landlord on account of loss, cost or damage which may arise by reason of such
claim. 

 (B) Landlord warrants and represents that Landlord has not dealt with any broker in connection with the consummation
of this Lease other than the broker, person or firm, if any, designated in Section 1.1 hereof; and in the event any claim is made against the Tenant relative to dealings by Landlord with brokers other than the Brokers, if any, designated in
Section 1.1 hereof, Landlord shall defend the claim against Tenant with counsel of Landlord’s selection first approved by Tenant (which approval shall not be 
  

 -51- 

 unreasonably withheld or delayed) and save harmless and indemnify Tenant on account of loss, cost or
damage which may arise by reason of such claim.. Landlord agrees that it shall be solely responsible for the payment of brokerage commissions to the Broker, if any, designated in Section 1.1 hereof. 
  

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

  

	8.10	The obligations of this Lease shall run with the land, and except as herein otherwise provided, the terms hereof shall be binding upon and shall inure to the benefit of the
successors and assigns, respectively, of Landlord and Tenant and, if Tenant shall be an individual, upon and to his heirs, executors, administrators, successors and assigns. Each term and each provision of this Lease to be performed by Tenant shall
be construed to be both a covenant and a condition. The reference contained to successors and assigns of Tenant is not intended to constitute a consent to subletting or assignment by Tenant. 

  

	8.11	Tenant agrees not to record the within Lease, but each party hereto agrees, on the request of the other, to execute a so-called Notice of Lease or short form lease “in form
recordable and complying with applicable law and reasonably satisfactory to both Landlord’s and Tenant’s attorneys. In no event shall such document set forth rent or other charges payable by Tenant under this Lease; and any such document
shall expressly state that it is executed pursuant to the provisions contained in this Lease, and is not intended to vary the terms and conditions of this Lease. 

  

	8.12	Whenever, by the terms of this Lease, notice shall or may be given either to Landlord or to Tenant, such notice shall be in writing and shall be hand delivered (provided the
delivery service provides a delivery receipt) or sent by registered or certified mail postage prepaid:

 -52- 

 If intended for Tenant, addressed to Tenant at the address set forth on the second page of this Lease
except that from and after the Commencement Date the address of Tenant shall be the Premises (or to such other address or addresses as may from time to time hereafter be designated by Tenant by like notice). 
 All such notices shall be effective when received provided that the same are not refused (in which caser the date such notice is first attempted to be
delivered shall be the effective date). 
 Where provision is made for the attention of an individual or department, the notice shall be
effective only if the wrapper in which such notice is sent is addressed to the attention of such individual or department. 
  

	8.13	Employees or agents of Landlord have no authority to make or agree to make a lease or any other agreement or undertaking in connection herewith. The submission of this document for
examination and negotiation does not constitute an offer to lease, or a reservation of, or option for, the Premises, and this document shall become effective and binding only upon the execution and delivery hereof by both Landlord and Tenant. All
negotiations, considerations, representations and understandings between Landlord and Tenant are incorporated herein and may be modified or altered only by written agreement between Landlord and Tenant, and no act or omission of any employee or
agent of Landlord shall alter, change or modify any of the provisions hereof.

to use and occupy the Premises) upon the payment of rent and other charges payable by Tenant under this Lease and the performance by Tenant of Tenant’s obligations hereunder. In confirmation of such subordination and recognition, Tenant shall
execute and deliver promptly such instruments of subordination and recognition as such mortgagee may reasonably request, subject to the receipt of such instruments of recognition from such mortgage as Tenant may reasonably request.

  

 -53- 

 Concurrently with the execution of this Lease, Landlord and Tenant shall execute a Nondisturbance,
Attornment and Subordination Agreement in the form attached, hereto as Exhibit I and thereafter Landlord shall cause the mortgagee of the Complex as of the Date of this Lease to execute such Agreement and Landlord shall deliver a fully executed

hereby agree to attorn to such mortgagee or successor and to recognize such mortgagee or successor as its landlord. If any holder of a mortgage which includes the Premises, executed and recorded prior to the date of this Lease, shall so elect, this
Lease and the rights of Tenant hereunder, shall be superior in right to the rights of such holder, with the same force and effect as if this Lease had been executed, delivered and recorded, or a statutory Notice hereof recorded, prior to the
execution, delivery and recording of any such mortgage. The election of any such holder shall become effective upon either notice from such holder to Tenant in the same fashion as notices from Landlord to Tenant are to be given hereunder or by the
recording in the appropriate registry or recorder’s office of an instrument in which such holder subordinates its rights under such mortgage to this Lease. 
  

	8.16	Recognizing that both parties may find it necessary to establish to third parties, such as accountants, banks, mortgagees or the like, the then current status of performance
hereunder, either party, on the request of the other made from time to time, will promptly furnish to ‘“ Landlord, or the holder of any mortgage encumbering the Premises, or to Tenant, as the case may be, a statement of the Status of any
matter pertaining to this Lease, including, without limitation, acknowledgments that (or the extent to which) each party is in compliance with its obligations under the terms of this Lease. Any such statement delivered by Tenant pursuant to this
Section 8.16 may be relied upon by any prospective purchaser or mortgagee of the Premises or any prospective assignee of any mortgagee of the Premises. 

  

	8.17	If Tenant shall at any time default in the performance of any obligation under this Lease, Landlord shall have the right, but shall not be obligated, to enter upon the Premises and
to perform such obligation notwithstanding the fact that no specific provision for such substituted performance by Landlord is made in this Lease with respect to such default. In performing such obligation, Landlord may make any reasonable payment
of money or perform any other act. All sums so paid by Landlord (together with interest at the rate of one and one-half percentage points over the then prevailing prime rate in Boston as set by The 

  

 -54- 

 First National Bank of Boston) and all necessary incidental costs and expenses in connection with the
performance of any such act by Landlord, shall be deemed to be additional rent under this Lease and shall be payable to Landlord immediately on demand. Landlord may exercise the foregoing rights without waiving any other of its rights or releasing
Tenant from any of its obligations under this Lease. 
  

	8.18	Any holding over by Tenant after the expiration of the term of this Lease shall be treated as a tenancy at sufferance at one hundred fifty percent (150%) of the rents and other
charges herein (prorated on a daily basis) and shall otherwise be on the terms and conditions set forth in this Lease, as far as applicable; provided, however, that neither the foregoing nor any other term or provision of this Lease shall be deemed
to permit Tenant to retain possession of the Premises or hold over in the Premises after the expiration or earlier termination of the Lease Term. 

  

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

  

	8.20	Tenant agrees that the security deposit specified in Section 1.1 shall be paid to Meredith & Grew, Inc. upon execution and delivery of this Lease, and that
Meredith & Grew, Inc. shall hold the same for the benefit of Landlord, throughout the term of this Lease (including the Extended Term(s), if applicable), subject to returning such deposit to Tenant as provided in this Section 8.20, as
security for the performance by Tenant of all obligations on the part of Tenant to be kept and performed. Upon receipt of notice from Landlord from time to time that Landlord is entitled to apply such deposit or a part thereof to Landlord’s
damages arising from a default of Tenant, Meredith & Grew, Inc. shall promptly deliver to Landlord the amount specified in Landlord’s notice, and Landlord shall have the right from time to time without prejudice to any other remedy
Landlord may have on account thereof, to apply such funds from such deposit delivered by Meredith & Grew, Inc. to Landlord’s damages arising from any default on the part of Tenant. If Landlord so applies all or any portion of such
deposit, Tenant shall within seven (7) days after notice from Landlord deliver cash to Meredith & Grew, Inc.

 in an amount sufficient to restore such deposit to the full amount stated in Section 1.1. Tenant not
then being in default, Meredith & Grew, Inc. shall return the deposit, or so much thereof as shall not have theretofore been applied in accordance with the terms of this Section 8.20, to Tenant on the expiration or earlier termination
of the term of this Lease and surrender possession of the Premises by Tenant to Landlord at such time. While Meredith & Grew, Inc. holds such deposit, such deposit shall be placed in a bank insured by the Federal Deposit Insurance
Corporation and the outstanding amount of such deposit shall earn interest at prevailing money market rates and on each anniversary of the Commencement Date, if no Event of Default exists, Meredith & Grew, Inc. shall pay to Tenant such
interest earned on such deposit during the prior one year period. Meredith & Grew, Inc. shall not commingle such deposit with other funds. If Landlord conveys Landlord’s interest under this Lease, at Landlord’s direction, the
deposit, or any part thereof not previously applied, may be turned Over by Meredith & Grew, Inc. to Landlord’s grantee, and, if so turned over, Tenant agrees to look solely to such grantee for proper application of the deposit in
accordance with the terms of this Section 8.20, and the return thereof in accordance herewith. 
 Neither the holder of any mortgage nor the
lessor in any ground lease on property which includes the Premises shall ever be responsible to Tenant for the return or application of any such deposit, whether or not it succeeds to the position of Landlord hereunder, unless such deposit shall
have been received in hand by such holder or ground lessor. 
 Provided (i) that no Event of Default then exists and (ii) Landlord
has not previously applied such deposit or any portion thereof in accordance with the terms of this Section 8.20, Meredith & Grew, Inc. shall return the outstanding, amount of such deposit to Tenant upon the first to occur of
(i) the first day of the sixty-first (61st) month of the Lease Term (not including any partial month following the Commencement Date) or (ii) seven (7) days prior to date of the filing of a registration statement with the

5.6.5 of this Lease, but such right shall not pass to any such sublessee of 35,000 square feet of rentable floor area or less of the Premises. Further, at the expiration of the Term of this Lease as it may be extended, and also in the case of a
subletting of more than fifty percent (50%) or more of the Rentable Area of the Premises in the aggregate, Landlord shall have the right to remove the signage provided to Tenant hereunder. Landlord’s obligation to provide such driveway
sign and such exterior Building sign shall be subject to the applicable provisions of the City of Waltham Zoning Code and any other applicable laws and regulations and to Landlord obtaining all necessary permits and approvals, provided that Landlord

“Parties”). 
 RECITALS 
 WHEREAS, Sublandlord and Subtenant have entered into a Sublease (the “Sublease”), dated as of January 6, 2006, pursuant to which the Sublandlord agreed to sublet approximately 51, 291 rentable square feet of office space
located at 195 West Street, Waltham, Massachusetts 02451. 
 WHEREAS, Subtenant, as subtenant, wishes to sublease from Sublandlord, and
Sublandlord, as Sublandlord, wishes to sublease to Subtenant, approximately 11,938 rentable square feet of additional space in the Premises shown as the cross hatched area on the attached Exhibit A (the “Expansion Sublease
Premises”) upon the terms and conditions hereinafter set forth. 
 WHEREAS, Effective as of the Expansion Date, Sublandlord and
Subtenant would like to amend the terms of the Sublease. 
 NOW, THEREFORE, in consideration of the foregoing, the mutual covenants contained
herein and other good an valuable consideration, the receipt and sufficiency of which are herby acknowledged, the Parties covenant and agree that the Sublease is hereby amended as follows: 
 1. Effective as of December 15, 2006 (the “Expansion Date”), the term “Sublease Premises” shall include the Expansion Sublease Premises.

 2. Effective as of the Expansion Date, Section 1, “Basic Data: Definitions” shall be amended by deleting the definition of “Fixed
Rent” and replacing it with the following text: 
  

			
	“Fixed Rent:	  	$1,312,001.75 per year”

 3. Effective as of the Expansion Date, the following shall be added as a new Section 3A: 
 “3A. IMPROVEMENTS TO EXPANSION. 
 A. Subtenant shall
expeditiously perform all of the construction of the interior improvements to the Expansion Sublease Premises necessary for Subtenant’s use of the Expansion Sublease Premises as contemplated hereunder (the “Subtenant’s Expansion
Work”); provided, however, that all of Subtenant’s Expansion Work shall be done in a good and workmanlike manner using first quality materials and in accordance with (i) the provisions of the Prime Lease applicable thereto,
(ii) all laws, rules, regulations and insurance requirements 

 applicable thereto and (iii) those certain plans and specifications to be constructed on behalf of Subtenant by a
reputable contractor and subject to the reasonable approval by Sublandlord (the “Subtenant’s Expansion Plans”). Notwithstanding anything to the contrary set forth in this Section 3 (A), Subtenant may not perform the
Subtenant’s Expansion Work unless the Subtenant’s Expansion Plans have been approved by Landlord. 
 B. Subtenant hereby covenants
and agrees, at its sole cost and expense and in accordance with the terms and provision of this Sublease, to initiate and thereafter diligently prosecute to completion the Subtenant’s Expansion Work. Subtenant further acknowledges and agrees
the Sublandlord shall have no obligation to perform any portion of the Subtenant’s Expansion Work, all of such work being the sole responsibility of Subtenant hereunder. 
 C. Sublandlord shall provide to Subtenant an allowance of $59,690.00 (the “Subtenant Expansion Allowance”) to be applied towards the cost of
the Subtenant’s Expansion Work (including, without limitation, the architect’s fee, improvements, tel/data wiring, moving and all other reasonable occupancy expenses in connection therewith). It is understood and agreed that the Subtenant
Expansion Allowance (or portions thereof) will be made available to Subtenant within thirty (30) days after Subtenant provides Sublandlord with invoices showing the actual cost of performing the applicable portion of the Subtenant’s
Expansion Work, and that such disbursement may occur at any time after the Expansion Date. To the extent the costs of the Subtenant’s Expansion Work exceed the Subtenant Expansion Allowance, Subtenant shall be solely responsible for such excess
costs and shall promptly pay the difference to the appropriate contractors and suppliers. 
 D. Notwithstanding the foregoing, Sublandlord
shall be under no obligation to apply any portion of the Subtenant Expansion Allowance for any purposes other than as provided in this Section 3, nor shall Sublandlord be deemed to have assumed any obligations, in whole or in part, of Subtenant
to any contractors, subcontractors, suppliers, workmen or materialmen. In addition, Sublandlord shall not be obligated to make any application of any portion of the Subtenant Expansion Allowance (i) for so long as (x) there shall be an
existing default of Subtenant or (y) there are any liens which are not bonded to the reasonable satisfaction of Sublandlord against Subtenant’s interest in the Sublease or against the Building or the Site arising out of any work performed
by Subtenant or any litigation in which Subtenant is a party or (ii) to the extent not requested by Subtenant prior to May 1, 2007. Further, in no event shall Sublandlord be required to make application of any portion of the Subtenant Expansion
Allowance on account of any supervisory fees, overhead, management fees or other payments to Subtenant, or any partner or affiliate of Subtenant. 
 4.

this Sublease, within thirty (30) 
  

 2 

 days of Subtenant’s receipt of an invoice thereof. If Subtenant fails to pay any rent when due, and such failure
continues for ten (10) days after written notice from Sublandlord thereof, such unpaid amount shall bear a five percent (5%) late charge, which will be immediately due and payable. Subtenant shall also pay Sublandlord, as Additional Rent,
all increases or escalations in operating expenses above the “Operating Expenses Allocable to the Premises” as defined in the Prime Lease for calendar year 2006 and all increases or escalations in real estate taxes above the “Landlord

entirety as follows: 
 “18. PARKING. Subtenant shall be entitled to all unreserved parking spaces dedicated to the Sublease Premises, of which 42
spaces will be located in the parking area in the basement of the Building. 
 6. Effective as of the Expansion Date, Section 19 of the Sublease shall
be deleted. 
 7. This Amendment No. 1 to Sublease is contingent upon, and shall not be effective until, Sublandlord obtains the written consent of the
Landlord to this Sublease as provided under the terms of the Prime Lease. All costs of obtaining such consent shall be borne by Sublandlord. In the event that the Landlord determines not to grant such consent, this Amendment No. 1 to Sublease
shall expire and be of no force or effect. 
 8. Except as amended hereby, the Sublease remains in full force and effect.
