 4. RENT. 

From and after the Rent Commencement Date (as hereinafter defined), Subtenant shall pay to Sublandlord monthly installments of annual base rent
(the “Base Rent”), which Base Rent shall be paid in advance on or before the first day of each calendar month in accordance with Section 3 (Rent) of the Lease. For purposes hereof, the “Rent Commencement

Premises for the Permitted Use. In the event Subtenant occupies fewer than [***] ([***]) full floors of the Subleased Premises for the Permitted Use prior to the [***] ([***]) monthly anniversary of the Commencement Date, then, until the Rent
Commencement Date occurs, Subtenant shall pay only its share of Expense Rent, Parking Charges and Subtenant Surcharges (but not Base Rent) proportionately allocable to the floors so occupied. If the Rent Commencement Date shall be on any day other
than the first day of a calendar month, Base Rent for the partial month shall be prorated based on the number of days in that month. Subtenant shall pay Base Rent in accordance with the following schedule:

 5. ADDITIONAL RENT. 

(a) In addition to the Base Rent and any other sums which Subtenant may be obligated to pay pursuant to any other provision of this Sublease,
from and after the Rent Commencement Date, Subtenant agrees to pay to Sublandlord as additional rent hereunder, in monthly installments based on Landlord’s Annual Estimates (as defined in Section 5(a) of the Lease), as and when such sums
are due and payable by Sublandlord under the Lease, or as otherwise hereinafter provided. 

  
 Portions of this
Exhibit, indicated by the mark “[***],” were omitted and have been filed separately with the Securities and Exchange Commission pursuant to the Registrant’s application requesting confidential treatment pursuant to Rule 24b-2 of the
Securities Exchange Act of 1934, as amended.

 (i) Subtenant’s Share of Administration Rent and Additional Rent (as such terms are defined
in Section 3 of the Lease) (collectively, “Expense Rent”). The term “Additional Rent” includes Operating Expenses attributable to the Premises. For purposes hereof, “Subtenant’s
Share” shall be a percentage, the numerator of which is the agreed rentable area of the then Subleased Premises, and the denominator of which is 380,111, the total combined rentable square feet in the 75 Binney Building and the 125 Binney
Building. Subtenant’s Share may increase or decrease, as the case may be, as additional area is added to or subtracted from the Subleased Premises pursuant to the terms hereof. As of the date of this Sublease, Subtenant’s Share is forty
two and nine tenths percent (42.9%), reflecting a numerator of 163,186 rentable square feet as the agreed rentable area of the Subleased Premises and a denominator of 380,111 rentable square feet; and 

(ii) all Parking Charges (as hereinafter defined) attributable to Subtenant’s Pro Rata Share of Parking Spaces in the Garage pursuant to
Section 10(b) of the Lease and Section 16 hereof; and 
 (iii) all Subtenant Surcharges (as hereinafter defined). As used
herein, the term “Subtenant Surcharges” shall mean any and all amounts, in addition to Expense Rent under Section 5(a)(i) and Parking Charges under Section 5(a)(ii) above, which become due and payable by Sublandlord to the
Landlord under the Lease, whether as “additional rent” or for any extra services or otherwise which would not have become due and payable but for the acts and/or failures to act of Subtenant under this Sublease or which are otherwise
attributable to the Subleased Premises for: (x) any increases in the Landlord’s fire, rent or other insurance premiums resulting from any act or omission of Subtenant, (y) any charges payable by Sublandlord under the Lease on account
of Subtenant’s use or maintenance of heating, ventilation or air conditioning, electricity, or other extra services requested by Subtenant and provided under the Lease for the benefit of Subtenant or the Subleased Premises, and (z) any
charges payable by Sublandlord under the Lease on account of any other additional service requested by Subtenant and as may be provided under the Lease to or for the benefit of the Subleased Premises, including but not limited to
Section 11(b) (Other Services).  
 (b) Subtenant shall pay the additional rents set forth in Section 5(a)(i) and
(ii) within five (5) business days after the presentation of statements therefor by Landlord or Sublandlord to Subtenant, and the additional rents set forth in Section 5(a)(iii) hereof within forty-five (45) days after the
presentation of statements therefor. Any failure or delay by Sublandlord in billing any sum set forth in this Section 5 shall not constitute a waiver of Subtenant’s obligation to pay the same in accordance with the terms of this Sublease,
but the time period for payment shall be extended accordingly. Annual reconciliations of payments for Expense Rent shall be made within the time frames provided for in Section 5(e) of the Lease. 

(c) In connection with any Sublandlord and Landlord meetings and/or discussions regarding the Annual Estimates for Operating Expenses pursuant
to Section 5(a) of the Lease (Annual Estimates), Sublandlord will give Subtenant reasonable prior written notice of all such “open book” cooperative meetings and/or discussions with Landlord and invite a representative of
Subtenant to attend and/or participate in same.

 (d) Sublandlord shall within five (5) business days of receipt furnish to Subtenant a copy
of each notice or statement from the Landlord affecting the Subleased Premises with respect to Subtenant’s obligations hereunder. If Sublandlord disputes the correctness of any such notice or statement and if such dispute is resolved in
Sublandlord’s favor, or if Sublandlord shall receive any refund of additional rent with or without a dispute, Sublandlord shall, within thirty (30) days of receipt of funds pay to Subtenant any refund (after deducting from the amount of
any such refund an equitable portion of all expenses, including court costs and reasonable attorneys’ fees, incurred by Sublandlord in resolving such dispute) received by Sublandlord in respect (but only to the extent) of any related payments
of additional rent made by Subtenant less any amounts theretofore received by Subtenant directly from the Landlord and relating to such refund; provided, however, that, if Sublandlord is required under the terms of the Lease to pay
such amounts pending the determination of any such dispute (by agreement or otherwise), Subtenant shall pay the full amount of the Base Rent, Expense Rent, Subtenant Surcharges and Parking Charges in accordance with this Sublease and the applicable
Landlord’s statement or notice. 
 (e) Subtenant shall have all audit rights and the benefit of all audit periods set forth under
Section 5 (Operating Expense Payments) of the Lease. 
 (f) Subtenant shall have the same rights as set forth in
Section 9(a) of the Lease to seek an abatement of Taxes provided Subtenant shall give Sublandlord notice at least twenty (20) days prior to the deadline for filing such requests. Sublandlord agrees to cooperate with Subtenant in connection
with Subtenant’s review of any Annual Statements, bills or other materials furnished by Landlord relating to the Subleased Premises and, upon request of Subtenant, to request from Landlord any additional supporting materials reasonably
requested by Subtenant in connection therewith and, at Subtenant’s sole cost and expense, to conduct an audit pursuant to the terms and conditions of Section 5(e)(iv) of the Lease, and/or to file an abatement pursuant to the terms and
conditions of Section 9(a) of the Lease. 
 (g) To the extent then accrued but not satisfied, Subtenant’s obligation to pay the
Base Rent, Expense Rent, Subtenant Surcharges, Parking Charges and all other sums payable under this Section 5 or otherwise under this Sublease shall survive the termination or earlier expiration of this Sublease. 

(h) The Base Rent, Expense Rent, Subtenant Surcharges, Parking Charges and any other amounts payable pursuant to this Sublease
(“Rent”) shall be paid by Subtenant to Sublandlord at the address first set forth above, or at such other place as Sublandlord may hereafter designate from time to time in writing, in lawful money of the United States of America, or
at Subtenant’s option, by wire transfer, as and when the same become due and payable, without demand therefor and without any deduction, set-off or abatement whatsoever except as otherwise provided herein. Any other amounts of additional rents

of Base Rent, Subtenant Surcharges, Parking Charges and all other costs, charges and expenses which Subtenant assumes, agrees or is obligated to pay to Sublandlord pursuant to this Sublease shall
be additional rent and, in the event of nonpayment thereof, Sublandlord shall have all the rights and remedies with respect thereto as are herein provided for in case of nonpayment of the Base Rent reserved hereunder (and subject to the same notice
and grace periods set forth in the Lease). 
 (i) Utilities are provided and paid for by Landlord in accordance with
Section 11(a) (Utilities and Services) of the Lease. In accordance with Section 11(a) of the Lease, Subtenant shall pay all costs or amounts due on account of any separately metered or sub-metered, as the case may be,
Utilities and/or other services which may be furnished to Subtenant or the Subleased Premises during the Sublease Term. Submeters for gas and electric shall be provided for and installed by Subtenant as part of the Subtenant Improvements. 

6. EXTENSION OPTION. 
 (a) Provided that at
the time of such exercise and upon the commencement of the Extended Term (i) there then exists no Default or condition which, with the giving of notice or passage of time or both, would constitute a Default, (ii) this Sublease is then in
full force and effect, and (iii) Subtenant or Subtenant’s Permitted Transferee is in actual occupancy of not less than [***] ([***]) full floors of the Subleased Premises, Subtenant shall have one (1) option to extend the Initial Term
of the Sublease (the “Extension Option”) for the Subleased Premises beginning on the day immediately following the Sublease Expiration Date (the “Extended Term Commencement Date”) and ending on March 30, 2030
(the “Extended Term”) on the same terms and conditions as set forth herein (other than Base Rent), by giving Sublandlord written notice of its election to exercise such Extension Option at least fifteen (15) months, but not
more than eighteen (18) months, prior to the expiration of the Initial Term. Provided the conditions set forth in the foregoing clauses (i), (ii) and (iii) shall have been satisfied, the giving of such notice by Subtenant shall
automatically extend the Initial Term for the Extended Term, and no instrument of renewal need be executed. In the event that Subtenant fails to give such notice to Sublandlord, this Sublease shall automatically terminate at the end of the Initial
Term, and Subtenant shall have no further option to extend the Initial Term, it being agreed that time is of the essence with respect to the giving of such notice. The Extended Term shall be on all the terms and conditions of this Sublease, except
that during the Extended Term, Subtenant shall have no further option to extend the Term and the rent for the Extended Term shall be determined as provided in Subsections 5(c) though (h), inclusive, below. Subtenant’s Extension Option shall be
personal to the original Subtenant and shall be void if the interest of Subtenant is assigned or transferred to any entity other than a Permitted Transferee. 

(b) The Base Rent for the Extended Term (“Extended Term Base Rent”) shall be equal to the Fair Market Rent for the Subleased
Premises, as hereinafter determined. In no event, however, shall the Extended Term Base Rent be less than [***] Dollars ($[***]) per rentable square foot of the Subleased Premises, increasing annually commencing on the first anniversary of the first
day of the Extended Term, and on each successive anniversary thereof, by [***]% of the Extended Term Base Rent in effect as of the end of the previous year. During the Extended Term, Subtenant shall continue to pay all Expense Rent, Subtenant
Surcharges and Parking Charges in accordance with Section 5 of this Sublease.

 (c) Sublandlord shall deliver to Subtenant Sublandlord’s determination of the Fair Market
Rent (as hereinafter defined) and rent escalations payable during the Extended Term (“Sublandlord’s Rent Determination”) within thirty (30) days after delivery of Subtenant’s notice of its election to exercise such
Extension Option (provided that Sublandlord shall not be obligated to deliver such determination to Subtenant earlier than fifteen (15) months prior to the expiration of the Initial Term). The term “Fair Market Rent” shall mean
the then fair market rental rate for the Subleased Premises taking into consideration all relevant factors that a tenant would pay upon an arms-length rental of the Subleased Premises on a direct lease as of the last day of the Initial Term. A
determination of the Fair Market Rent payable for the Subleased Premises during the Extended Term shall be made in the manner described in subsections (d) through (h), inclusive, below. 

(d) If, on or before the date which is sixty (60) days following the date of Sublandlord’s Rent Determination Notice, Subtenant has
not agreed with Sublandlord’s determination of the Fair Market Rent and the rent escalations applicable during the Extended Term after negotiating in good faith, Subtenant may by written notice to Sublandlord delivered not later than the last
day of such sixty (60) day period, elect arbitration as described in Subsections 5(e), (f) and (g) below. If, on or before the last day of such sixty (60) day period, Subtenant does not either give written notice to Sublandlord
of either Subtenant’s acceptance of Sublandlord’s Rent Determination or Subtenant’s election of arbitration, Subtenant shall be deemed to have accepted Sublandlord’s Rent Determination, and Sublandlord’s Rent Determination
of the Fair Market Rent and rent escalations shall be the Fair Market Rent and rent escalations for the Subleased Premises during the Extended Term. 

(e) Within ten (10) business days of Subtenant’s notice to Sublandlord of its election to arbitrate Fair Market Rent and escalations,
each party shall deliver to the other a proposal containing the Fair Market Rent and escalations that the submitting party believes to be correct (“Extension Proposal”). If either party fails to timely submit an Extension Proposal,
with an additional five (5) business days after notice that the same has not been received, then the other party’s submitted proposal shall determine the Base Rent and escalations for the Extended Term. If both parties submit Extension
Proposals, then Sublandlord and Subtenant shall meet within seven (7) days after delivery of the last Extension Proposal and make a good faith attempt to mutually appoint a single Arbitrator (and defined below) to determine the Fair Market Rent
and escalations. If Sublandlord and Subtenant are unable to agree upon a single Arbitrator, then each shall, by written notice delivered to the other within ten (10) days after the meeting, select an Arbitrator. If either party fails to timely
give notice of its selection for an Arbitrator, the other party’s submitted proposal shall determine the Base Rent and escalations for the Extended Term. The two (2) Arbitrators so appointed shall, within five (5) business days after
their appointment, appoint a third Arbitrator. If the two (2) Arbitrators so selected cannot agree on the selection of the third Arbitrator within the time above specified, then either party, on behalf of both parties, may request such
appointment of such third Arbitrator by application to any state court of general jurisdiction in the jurisdiction in which the Subleased Premises are located, upon ten (10) days’ prior written notice to the other party of such intent.

 10 








 (f) The decision of the Arbitrator(s) shall be made within thirty (30) days after the
appointment of a single Arbitrator or the third Arbitrator, as applicable. If there is a single Arbitrator, the decision of the single Arbitrator shall be final and binding upon the parties. If there are three (3) Arbitrators, the third
Arbitrator shall chose in full one (1) of the decisions of the other two (2) Arbitrators, and such choice shall be final and binding upon the parties. Each party shall pay the fees and expenses of the Arbitrator appointed by or on behalf
of such party and the fees and expenses of the third Arbitrator shall be borne equally by both parties. If, pursuant to the preceding provisions of this Section 6, Fair Market Rent and escalations have not been determined as of the first day of
the Extended Term, Subtenant shall pay on account of Base Rent the rent specified by Sublandlord in Sublandlord’s Rent Determination as the Fair Market Rent until such determination is made. After the determination of the Fair Market Rent and
escalations, the parties shall make any necessary adjustments to such payments made by Subtenant. 
 (g) An “Arbitrator”
shall be any person appointed by or on behalf of either party or appointed pursuant to the provisions hereof and: (i) shall be (A) a member of the American Institute of Real Estate Appraisers with not less than 10 years of experience in
the appraisal of improved office and high tech industrial real estate in Cambridge, Massachusetts, or (B) a licensed commercial real estate broker with not less than 15 years’ experience representing landlords and/or tenants in the leasing
of high tech or life sciences space in Cambridge, Massachusetts, (ii) devoting substantially all of their time to professional appraisal, brokerage work, or institutional real estate advisory work, as applicable, at the time of appointment and
(iii) be in all respects impartial and disinterested (i.e., shall not have been engaged by either Sublandlord or Subtenant, or their respective affiliates, as their exclusive representative during the immediately preceding 2-year period). 

(h) If Subtenant shall validly exercise the Extension Option, it shall promptly, after such election and the determination of the Fair Market
Rent and escalations for the Extended Term, enter into an amendment to the Sublease incorporating the terms thereof, but failure to do so shall have no effect on Subtenant’s agreement to extend the Sublease Term for the Extended Term. 

7. ROFO RIGHTS. 
 (a) Provided that at the
time of such availability and at the time Subtenant elects to lease such Offered Space (as hereinafter defined) (i) there then exists no Default or condition which, with the giving of notice or passage of time or both, would constitute a
Default, (ii) this Sublease is then in full force and effect, and (iii) original Subtenant named under this Sublease or Subtenant’s Permitted Transferee is in actual occupancy of not less than [***] ([***]) full floors of the
Subleased Premises (except during any period prior to initial occupancy of the Subleased Premises), if, at any time during the Initial Term all or any portion of the Premises within the 125 Binney Building, except as provided below
(the “First Offer Space”), shall become available for sublease (and specifically excluding any portion of the Premises which Sublandlord desires to retain for its own use or sublease to any entity controlled by, controlling, or
under common control with, Sublandlord), Sublandlord shall notify Subtenant in writing (the “ROFO Notice”), identifying the space available (the “ROFO Offered Space”) and shall set forth the terms and


  
 Portions of this
Exhibit, indicated by the mark “[***],” were omitted and have been filed separately with the Securities and Exchange Commission pursuant to the Registrant’s application requesting confidential treatment pursuant to Rule 24b-2 of the

conditions on which Sublandlord is willing to lease the ROFO Offered Space. Notwithstanding the foregoing, in no event shall the First Offer Space include or shall this first offer right apply to
(i) any Contraction Space (as hereinafter defined) which may have been deleted from the Subleased Premises in accordance with Section 8, or (ii) any portion of the first
(1st) floor allocated for a café or food service area. 
 (b) Subtenant
shall have the right (the “First Offer Right”), by giving written notice to Sublandlord within ten (10) business days after receipt of the ROFO Notice, time being of the essence, to lease the ROFO Offered Space on the terms
offered by Sublandlord, and Subtenant’s election to lease the ROFO Offered Space shall constitute a binding agreement to lease the ROFO Offered Space on the terms offered by Sublandlord. If Subtenant shall so elect to lease the ROFO Offered
Space, it shall promptly after such election enter into an amendment to this Sublease incorporating the terms contained in Sublandlord’s notice, but failure to do so shall have no effect on Subtenant’s agreement to lease the ROFO Offered
Space. If Subtenant shall not elect to lease the ROFO Offered Space within such ten (10) business day period, then Subtenant shall have no further rights under this Section with respect to the ROFO Offered Space, and Sublandlord shall be free
to sublease any or all of such space to a third party or parties from time to time on such terms and conditions as Sublandlord may deem appropriate; provided, however, that if Sublandlord does not lease the Offered Space to a third party or parties
within [***] after giving such notice to Subtenant (as described in subsection (d) below), and such ROFO Offered Space is still available for sublease (or thereafter if such ROFO Offered Space shall again become available for sublease), then
Sublandlord shall not lease the ROFO Offered Space to any third party or parties without first again offering the ROFO Offered Space to Subtenant pursuant to the terms hereof. Nothing herein shall be construed to limit Subtenant’s rights under
this Section with respect to space within the First Offer Space other than the ROFO Offered Space. The First Offer Right shall be personal to the original Subtenant named in this Sublease and shall be void if the interest of the Subtenant originally
named in this Sublease is assigned or otherwise transferred except to a Permitted Transferee. 
 (c) For purposes of this Section, space
shall not be deemed to be “available for sublease” (i) in the event that Sublandlord desires to utilize such space for its own purposes or to sublease any of the First Offer Space to any entity controlled by, controlling, or under
common control with, Sublandlord, or (ii) in the event that Sublandlord and an existing occupant of such space desire to renew or extend such existing occupant’s sublease or enter into a new sublease; and Subtenant’s rights under this
Section shall be subject and subordinate to any such extension, renewal, or subleasing to such existing occupant occupying its then current space. 

(d) If Subtenant shall not elect to lease the ROFO Offered Space pursuant to an offer from Sublandlord under this Section as aforesaid, then
notwithstanding anything to the contrary contained in the preceding paragraph, if Sublandlord shall thereafter (i) fail to lease the Offered Space for a Net Effective Rental (as hereinafter defined) of not less than [***] percent ([***]%) of
the Net Effective Rental proposed to Subtenant within [***] from the date of the ROFO Notice, and (ii) such space remains available for sublease, and Sublandlord shall propose to lease the ROFO Offered Space for a Net Effective Rental of less
than [***] percent ([***]%) of the Net Effective Rental proposed to Subtenant, Sublandlord shall re-offer the ROFO Offered Space to Subtenant pursuant to this Section. The term “Net Effective Rental” shall mean for purposes

of this Section, with respect to any proposed lease of ROFO Offered Space, the net present value, determined as of the effective date of the proposed sublease, using a discount rate of [***]
percent ([***]%), of the aggregate of all Base Rent, Expense Rent, Parking Charges and Subtenant Surcharges payable under the proposed sublease, discounted from the date such payment would have been made under the proposed sublease to the
commencement date of the proposed sublease, after deducting therefrom the amount of all inducements (such as, by way of example only, work allowances, work letters or rent abatements) that are (or will be) granted by Sublandlord to such subtenant in
respect thereof, discounted, using a discount rate of [***] percent ([***]%), from the date that such inducements were to have been given under the proposed sublease to the commencement date of the proposed sublease. 

(e) Upon any re-offering of ROFO Offered Space to Subtenant following any reduction of the price or expiration of the [***] period as provided
in subsections (b) and (d) above and if such space remains available for sublease, Subtenant shall have five (5) business days after Subtenant’s receipt of a ROFO Notice to exercise its right hereunder, by giving written notice
to Sublandlord, time being of the essence, to lease the ROFO Offered Space on the terms offered by Sublandlord, and Subtenant’s election to lease the ROFO Offered Space shall constitute a binding agreement to lease the ROFO Offered Space on the
terms offered by Sublandlord. 
 (f) Effective as of Sublandlord’s delivery to Subtenant of the applicable ROFO Offered Space,
(i) the definition of Subleased Premises shall be modified to include the applicable ROFO Offered Space; (ii) Base Rent shall be increased proportionately to include the applicable ROFO Offered Space; (iii) Subtenant’s Pro Rata
Share of Parking Spaces in the Garage shall be increased proportionately; and (iv) Subtenant’s Share in Section 5(a)(i) hereof shall be increased proportionately to include the ROFO Offered Space. Further, as of the date of
Sublandlord’s delivery to Subtenant of the applicable ROFO Offered Space, Subtenant shall pay Subtenant’s Share of Expense Rent, Subtenant Surcharges and Parking Charges with respect to the applicable ROFO Offered Space in accordance with
Section 5(a) of this Sublease. 
 (g) Promptly after Sublandlord’s delivery to Subtenant of the applicable ROFO Offered Space,
Sublandlord and Subtenant shall execute an amendment to this Sublease confirming the terms of the expansion, but failure to do so shall have no effect on Subtenant’s agreement to lease the applicable ROFO Offered Space. 

8. CONTRACTION OPTION. 
 (a) Provided that
(i) the Subleased Premises include at least [***] ([***]) full floors of the 75 Binney Building, including Floors [***] and [***], (ii) there then exists no Default or condition which, with the giving of notice or passage of time or both,
would constitute a Default, and (iii) this Sublease is then in full force and effect, Subtenant shall have the one-time right, at Subtenant’s election, to reduce the size of the Subleased Premises (the “Contraction
Option”) by deleting the [***] of the Subleased Premises (the “Contraction Space”), effective upon the seventh (7th) anniversary of the Rent Commencement Date (the
“Contraction Date”), provided further that:

 (1) Subtenant shall exercise the Contraction Option by written notice given to Sublandlord no
later than December 31, 2021 (the “Contraction Notice”); 
 (2) this Sublease is in full force and effect as to all of
the Subleased Premises both as of the date Subtenant delivers the Contraction Notice (provided that Sublandlord shall have the right to waive this condition) and as of the Contraction Date; 

(3) there then exists no uncured Default both as of the date Subtenant delivers the Contraction Notice (provided that Sublandlord shall have
the right to waive this condition) and as of the Contraction Date; and 
 (4) at least sixty (60) days prior to the Contraction Date,
Subtenant shall pay to Sublandlord by wire transfer, certified check or bank check, an amount equal to Sublandlord’s Unamortized Costs (as hereinafter defined). 

“Sublandlord’s Unamortized Costs” shall mean an amount equal to the sum of the unamortized amounts, as of the Contraction Date and
assuming straight line amortization over a period of ten (10) years, of (1) the Base TI Allowance (as hereinafter defined) paid by Sublandlord, allocable on a proportionate basis to the Contraction Space, (2) brokerage commissions
paid by Sublandlord in connection with this Sublease, allocable on a proportionate basis to the Contraction Space, (3) legal fees incurred by Sublandlord in connection with this Sublease, allocable on a proportionate basis to the Contraction
Space, and (4) interest on the foregoing items (1) through (3) at the rate of [***] percent ([***]%) per annum. Prior to Subtenant’s delivery of the Contraction Notice, Subtenant shall request Sublandlord’s written statement
of Sublandlord’s Unamortized Costs for the Contraction Space. Within twenty (20) business days after receipt of Subtenant’s request, Sublandlord shall deliver to Subtenant Sublandlord’s statement of Sublandlord’s Unamortized
Costs. 
 (b) In the event that Subtenant fails to deliver the Contraction Notice to Sublandlord in accordance with the terms hereof,
Subtenant shall have no further option to reduce the size of the Subleased Premises under this Section 8, it being agreed that time is of the essence with respect to the giving of such Notice. 

(c) Time is of the essence with respect to all of the conditions and limitations set forth in this Section upon Subtenant’s exercise of
the Contraction Option. Subtenant shall surrender the Contraction Space on the Contraction Date in accordance with the surrender and restoration provisions of the Sublease and the Lease, as if the Contraction Date were the Expiration Date with
respect to the Contraction Space only. If Subtenant should fail to so surrender the Contraction Space on the Contraction Date, such failure shall constitute a Default and holding over with respect to the Contraction Space and Sublandlord may
exercise any and all available rights and remedies under the Sublease and the Lease, at law or in equity, by reason of such Default and holding over.

confirming such adjustments, but failure to do so shall have no effect on the Contraction Date. 
 9. SECURITY DEPOSIT. No security deposit shall be
required to be provided by Subtenant.

Section 18 (Restoration) and Section 19 (Eminent Domain). Subtenant agrees to look solely to Landlord, as the owner of the Project, for the furnishing of such services, for providing the Base TI Allowance, and for the
performance of such Landlord terms, covenants, conditions or obligations. In the event that Landlord shall fail to furnish such services, or to provide the Base TI Allowance, or to perform any of the terms, covenants, conditions or obligations
contained in the Lease on its part to be performed, Sublandlord shall be under no obligation or liability whatsoever to Subtenant for such failure. 

(b) Subtenant shall notify Sublandlord of any Material Services Failure with respect to the Subleased Premises, and Subtenant shall have the
same rights as Sublandlord with respect to equitable abatement of Base Rent and Subtenant’s Share of Additional Rent proportionately allocable to the Subleased Premises as provided in Section 11 of the Lease. 

(c) Notwithstanding anything to the contrary herein, nothing in Section 15(a) above shall derogate from Sublandlord’s responsibility
to notify Landlord and seek Landlord’s performance or rectification resulting from any Subtenant’s notice regarding a Landlord default or from Sublandlord’s obligation to cooperate with Subtenant under the terms and conditions set
forth herein. Upon written notice from Subtenant to Sublandlord of Landlord’s failure to perform its obligations under the Lease, Sublandlord shall notify Landlord to that effect and demand Landlord’s performance or rectification of such
breach. Sublandlord shall, at Subtenant’s sole cost and expense (subject to reimbursement and/or recoupment and the same rights of offset as forth in Section 31(b) of the Lease), use such best efforts as Subtenant may reasonably request to
cause Landlord to comply with its obligations under the Lease, including, without limitation, exercising Sublandlord’s rights of self-help under Section 31(b) of the Lease. In addition, upon any failure of Landlord to fund all or any
portion of Subtenant’s Base TI Allowance under and in accordance with this Sublease, Subtenant shall be entitled to the same rights of offset as provided under Section 31(c) Right of Base Rent Offset for TI Allowance Default of
Landlord of the Lease. 
 (d) To the extent that Sublandlord is entitled to and actually receives an abatement of Rent due under the
Lease in accordance with Section 11, Section 18, Section 19 or Section 31 of the Lease due to the circumstances specifically described in the Lease (a “Lease Rent Abatement”), which circumstances adversely affect
the Subleased Premises, then to the extent such Lease Rent Abatement is allocable to the Subleased Premises (or any portion thereof) then Subtenant shall be entitled to a corresponding abatement of Rent due under the Sublease (a “Sublease
Rent Abatement”), it being understood that the Sublease Rent Abatement shall not exceed either the number of days or the ratably allocable portion of the Subleased Premises of the Lease Rent Abatement. Subtenant may notify Landlord and
Subtenant of any such condition causing untenantability in the Premises. Subtenant may request that Sublandlord make a demand upon Landlord under the Lease, if applicable, with respect to such untenantability.

 16. PARKING. 

(a) Subject to the terms and conditions of Section 10 (Parking) of the Lease, commencing on the Rent Commencement Date, Subtenant
shall be obligated to pay, in addition to Base Rent, Expense Rent and Subtenant Surcharges hereunder, and also as Additional Rent hereunder in respect of Subtenant’s Pro Rata Share of Parking Spaces in the Garage, the market rate monthly charge
therefor designated by Landlord (“Parking Charges”). As of July 1, 2015 the Parking Charge is at the rate of $[***]/month per Parking Space. For purposes hereof, Subtenant’s “Pro Rata Share of Parking
Spaces” shall initially be [***] ([***]) parking spaces in the Garage, to be adjusted to Subtenant’s Share of the parking spaces provided to the Premises in accordance with the Lease upon any adjustment of the size of the Subleased
Premises in accordance with the terms of this Sublease. Subtenant’s allocated parking spaces are inclusive of any parking spaces in areas designated for exclusive parking for Subtenant as provided in Section 16(b) below. All such Parking
Spaces shall be used solely for Subtenant’s employees working in the 75 Binney Building and for the guests, clients and invitees of Subtenant working in the 75 Binney Building. Notwithstanding any provision hereof to the contrary, by notice
given to Sublandlord on or before the Rent Commencement Date, Subtenant may elect, to exclude and relinquish all or any portion of Tenant’s Pro Rata Share of Parking Spaces, and, in such event, Subtenant shall not be obligated to pay the
monthly parking charge for any relinquished Parking Spaces. 
 (b) Subject to Landlord’s written approval, Subtenant shall have the
right to use the B1 Space for parking exclusively for Subtenant’s employees and the parking area designated as “Portion of Parking B1 Level to be segregated via barrier arm” on the plan attached hereto as Exhibit “B-2”, and
to install an arm barrier to vehicular entry, which rights to the B1 Space shall be subject to the access rights of Landlord and Sublandlord as provided in the Lease, and to the rights of the retail tenants in the Building to access the retail and
restaurant related equipment located within the B1 Space. 
 (c) Subtenant’s Pro Rata Share of Parking Spaces shall be
(i) proportionately reduced in the event Subtenant exercises its Contraction Option pursuant to Section 8 (Contraction Option) hereof, and/or (ii) proportionately increased in the event Subtenant exercises its First Offer Right
with respect to any First Offer Space pursuant to Section 7 (ROFO Rights) hereof. Subject to the Landlord’s rules and regulations applicable to the Garage, and to Landlord’s consent, Sublandlord shall not grant any other
subtenant or occupant of the 75 Binney Building the right to park on the “B1” parking level located directly below “Floor L1” of the 75 Binney Building. 

17. GENERATOR/COMMUNICATIONS EQUIPMENT. Subject to the terms and conditions of the Lease, including without limitation Exhibit J (Rooftop Rights)
thereto, Subtenant shall have the right to use a portion of the roof on the 75 Binney Building, subject to the approval of Landlord and in a location designated by Landlord, for installation of Subtenant’s Rooftop Equipment (including but not
limited to a standby generator and communications equipment). Subtenant acknowledges and agrees that Landlord’s obligation to provide a standby generator or emergency back-up power is outlined under Section 11(c)
(Tenant’s Standby Generator) of the Lease, the Work Letter, and the Landlord/Tenant Matrix attached hereto as Exhibit “D”/Schedule 2.1.

 18. COMPETITORS. Provided that (i) there then exists no Default or condition which, with the giving
of notice or passage of time or both, would constitute a Default, and (ii) this Sublease is then in full force and effect, Sublandlord agrees not to enter into any assignment, lease, sublease (or consent to a sub-sublease) for any portion of
the Premises to any company that is in competition with the business of Subtenant (a “Competitor”) and which Competitor is specifically listed on Exhibit “E” attached hereto. 

19. ACCESS. Subtenant and Sublandlord confirm that the Sublease incorporates by reference Section 32 (Inspection and Access) of the Lease,
permitting access to the Subleased Premises by Landlord and by Sublandlord. 
 20. INDEMNIFICATION; INSURANCE. 

(a) The parties confirm that the provisions of Section 16 (Indemnification) of the Lease are incorporated herein by reference. 

(b) The parties confirm that the provisions of Section 17 (Insurance) of the Lease are incorporated herein by reference. Subtenant
shall carry all insurance required pursuant to be carried by the tenant pursuant to Section 17(b) of the Lease, specifically naming both Sublandlord and Landlord as additional insureds. 

(c) Sublandlord hereby approves the following waivers to Section 17(b) of the Lease, subject to Landlord’s written approval of the
same for Landlord and Subtenant: (i) eliminate requirement to include “agents” as additional insured, (ii) policyholder rating of A-, (iii) acceptance of a policy with no hostile fire exclusion rather than a hostile fire
endorsement, (iv) waiver of a “per location” endorsement, and (v) acceptance of certificates of insurance issued by an insurer or agent rather than copies of actual complete policies. 

(d) Notwithstanding anything to the contrary contained in this Sublease or in the Lease, and subject to the written consent of Landlord, at
Subtenant’s option, for so long as (i) original Subtenant named under this Sublease is subleasing the entire Subleased Premises, (ii) no Default (as defined in Section 25 below) exists, (iii) Subtenant maintains a credit
rating from Standard & Poors of “AAA” and a credit rating from Moody’s of “Aaa”, or better, (iv) Subtenant has a net worth in excess of [***] Dollars ($[***]), and (v) Subtenant maintains a program of
self-insurance with respect to its properties generally, which program is administered and monitored in accordance with accepted standards of the insurance industry by professional insurance personnel retained or employed by Subtenant, Subtenant may
self-insure for some or all of the insurance required under Section 17 (Insurance) of the Lease. Any undertaking by Subtenant to self-insure pursuant to this section shall not relieve Subtenant from any of Subtenant’s other
obligations under the Lease or this Sublease, nor shall it serve to adversely affect Sublandlord or Landlord. The rights and obligations of Sublandlord shall remain the same as if Subtenant had obtained and maintained separate insurance from an
independent institutional insurer of recognized responsibility for the coverages as provided herein, including the application of the waivers and releases in Section 22(c) Waiver of Subrogation under the Lease.


  
 Portions of this
Exhibit, indicated by the mark “[***],” were omitted and have been filed separately with the Securities and Exchange Commission pursuant to the Registrant’s application requesting confidential treatment pursuant to Rule 24b-2 of the
Securities Exchange Act of 1934, as amended. 


  
 20 








 
Subtenant shall be liable as a self-insurer for the same coverages and the same amount of insurance as would Subtenant’s insurer if Subtenant maintained the insurance described in this
Section and Section 17 of the Lease. 
 (e) Subject to all of the other requirements of this Section 20, Sublandlord consents to
self-insurance for some or all of the insurance required by this Section and Section 17 of the Lease, provided that (i) the original Subtenant maintains a program of insurance substantially in accordance with original Subtenant’s
program of insurance in effect as of the date of this Sublease as set forth on the certificates of insurance with respect to both property insurance and liability insurance whereby (i) Subtenant maintains its own captive insurance company,
(ii) Subtenant maintains re-insurance in amounts sufficient to satisfy the requirements of this Section 21 which re-insurance provides to Sublandlord direct access to re-insurers via a “cut-through” endorsement and (iii) the
re-insurers satisfy the requirements of Section 17 of the Lease. Subtenant shall give Sublandlord prompt notice of any material change in Subtenant’s program of insurance. 

(f) The parties confirm that the provisions of Section 30 (Environmental Requirements) of the Lease are incorporated herein by reference
(except for subsection 30(c) which is excluded). Each of Sublandlord and Subtenant agrees to comply with the Environmental Requirements set forth in the Lease. Each of Sublandlord and Subtenant shall indemnify the other to the extent of any damage
caused by Hazardous Materials brought upon the Premises or the Subleased Premises by such party in accordance with the same indemnification provisions as provided in Section 30 of the Lease. 

(g) The parties confirm that the provisions of Section 16 (Indemnification) of the Lease are incorporated herein by reference. In
addition, each of Sublandlord and Subtenant agrees to hold the other harmless from Claims caused by its negligence or willful misconduct in connection with the use or control of the New Atrium Area in accordance with the same indemnification
provisions as provided in Section 16 of the Lease. 
 21. ASSIGNMENT AND SUBLETTING. 

(a) General Prohibition. Without Sublandlord’s and Landlord’s prior written consent, subject to and on the conditions
described in this Section 21 and subject to the terms of this Section 21, Subtenant shall not, directly or indirectly, voluntarily or by operation of law, assign this Sublease or sub-sublease the Premises or any part thereof
or mortgage, pledge, or hypothecate its leasehold interest or grant any concession or license within the Subleased Premises, and any attempt to do any of the foregoing shall be void and of no effect. Except as provided in Section 21(b)
below, if Subtenant is a corporation, partnership or limited liability company, the shares or other ownership interests thereof which are not actively traded upon a stock exchange or in the over-the-counter market, a transfer or series of transfers
whereby 50% or more of the issued and outstanding shares or other ownership interests of such corporation are, and voting control is, transferred (but excepting transfers upon deaths of individual owners) from a person or persons or entity or
entities which were owners thereof at time of execution of this Sublease to persons or entities who were not owners of shares or other ownership interests of the corporation, partnership or limited liability company at time of execution of this
Sublease, shall be deemed an assignment of this Sublease requiring the consent of Sublandlord as provided in this Section 21. Notwithstanding the foregoing, any public offering of shares or other ownership interest in Subtenant shall not
be deemed an assignment. 

  
 Portions of this
Exhibit, indicated by the mark “[***],” were omitted and have been filed separately with the Securities and Exchange Commission pursuant to the Registrant’s application requesting confidential treatment pursuant to Rule 24b-2 of the

 21 








 (b) Permitted Transfers. If Subtenant desires to assign, sublease, hypothecate or
otherwise transfer this Sublease or sublet the Subleased Premises (or a portion thereof) other than pursuant to a Permitted Assignment (as defined below) then at least 15 days, but not more than 45 days, before the date Subtenant desires the
assignment or sublease to be effective (the “Assignment Date”), Subtenant shall give Sublandlord a notice (the “Assignment Notice”). The Assignment Notice shall set forth the portion of the Subleased Premises
to be made available (the “Offered Space”) and the terms and conditions upon which such Offered Space is to be available including the proposed term and all relevant financial terms. At Subtenant’s option the Assignment Notice
may identify a specific proposed assignee or subtenant and the material terms and conditions of the proposed transaction (a “Specific Assignment Notice”). A Specific Assignment Notice shall include a copy of an executed Letter of
Intent or Term Sheet setting forth all materials terms and conditions of the proposed assignment or sublease, information about the proposed assignee or sublessee, including the proposed use of the Subleased Premises and any Hazardous Materials
proposed to be used, stored handled, treated, generated in or released or disposed of from the Subleased Premises, the Assignment Date, any relationship between Subtenant and the proposed assignee or sublessee, and such other information as
Sublandlord may deem reasonably necessary or appropriate to its consideration whether to grant its consent. If, after having submitted an Assignment Notice, Subtenant shall identify a specific third party assignee or subtenant for such Offered
Space, Subtenant shall submit a Specific Assignment Notice with respect to such Offered Space. Sublandlord may, by giving written notice to Subtenant within 2 months after receipt of the Assignment Notice (which period shall be reduced to 15
business days in the case of a Specific Assignment Notice): 
 (i) in the case of a Specific Assignment Notice, grant such consent, which
consent shall not be unreasonably withheld, conditioned or delayed, including reasonable approval of the assignee, transferee or subtenant, its net worth and the proposed use of the Offered Space (and such consent may be subject to Landlord’s
and Sublandlord’s further right to reasonably approve the final form of documentation of such transaction); 
 (ii) in the case of a
Specific Assignment Notice, refuse such consent, in its sole and absolute discretion, if: (x) at the time of such notice Sublandlord has other space then available for sublease; or (y) concerns any transferee, assignee or subtenant which,
in Sublandlord’s or Landlord’s reasonable judgment, is engaged in areas of scientific research or other business concerns that are controversial such that they may (1) attract or cause negative publicity for or about the 75 Binney
Building or the Project, (2) negatively affect the reputation of the 75 Binney Building, the Project or Sublandlord, or (3) attract protestors to the 75 Binney Building; or (z) concerns any transferee, assignee or subtenant which has
engaged in mismanagement or improper disposal of Hazardous Materials (unless the same has been, or is reasonably in the process of being, corrected by the transferee, assignee or subtenant); 

  
 Portions of this
Exhibit, indicated by the mark “[***],” were omitted and have been filed separately with the Securities and Exchange Commission pursuant to the Registrant’s application requesting confidential treatment pursuant to Rule 24b-2 of the
Securities Exchange Act of 1934, as amended. 


  
 22 








 (iii) in the case of an Assignment Notice which is not a Specific Assignment Notice, waive any
right to terminate the Sublease (or sublease from Subtenant) as to the Offered Space for a period of 9 months following the Assignment Notice, during which period Sublandlord and Landlord shall continue to have the right to reasonably approve any
prospective subtenant or assignee of the Offered Space in the same manner as provided in subsections (i) and (ii) above; or 
 (iv)
recapture the Offered Space pursuant to the provisions of Section 21(g) below as of the Assignment Date, in the event that the proposed transaction is either: (x) an assignment of this Sublease; or (y) a Full Term Third Party Sublease
(as hereinafter defined). A “Full Term Third Party Sublease” is defined as a sublease of the entirety, or any portion, of the Subleased Premises, to anyone other than a Permitted Transferee, for a term which expires at or within 24
months prior to the expiration of the then current Sublease Term. 
 Subtenant shall reimburse each of Sublandlord and Landlord for their
respective reasonable out-of-pocket expenses in connection with its consideration of any Assignment Notice, up to a combined maximum of $[***] in connection with any Assignment Notice. Notwithstanding the foregoing, Sublandlord’s consent to an
assignment of this Sublease or a subletting of any portion of the Subleased Premises to any entity controlling, controlled by or under common control with Subtenant (a “Permitted Assignment”) shall not be required, provided
that Sublandlord shall have the right to reasonably approve the form of any such sublease or assignment. In addition, Subtenant shall have the right to assign this Sublease, without obtaining Sublandlord’s prior written consent, to a
corporation or other entity which is a successor-in-interest to Subtenant, by way of merger, consolidation, recapitalization or corporate reorganization, or by the purchase of all or substantially all of the assets or the ownership interests of
Subtenant (“Permitted Successor”) provided that (i) such merger or consolidation, or such acquisition or assumption, as the case may be, is for a good business purpose and not principally for the purpose of transferring the
Sublease, and (ii) the net worth (as determined in accordance with GAAP) of the assignee is not less than the net worth (as determined in accordance with GAAP) of Subtenant as of the date of this Sublease, and (iii) such assignee shall
agree in writing to assume all of the terms, covenants and conditions of this Sublease arising after the effective date of the assignment (a “Permitted Assignment”). Any transferee pursuant to a Permitted Assignment is a
“Permitted Transferee”. Subtenant shall give at least upon 10 business days prior written notice to Sublandlord of any Permitted Assignment, except that if, in connection with a transfer to a Permitted Successor, Subtenant is under
a legal obligation of confidentiality, either by reason of applicable Legal Requirements or pursuant to a confidentiality agreement to which Subtenant is subject, then Subtenant shall give Sublandlord notice of such Permitted Assignment as soon as
reasonably possible after such confidentiality restriction lapses or is waived by the party having the right to enforce such restriction. 

Any refusal by Sublandlord to grant its consent as provided herein shall specify in reasonable detail the reasons for such disapproval. 

  
 Portions of this
Exhibit, indicated by the mark “[***],” were omitted and have been filed separately with the Securities and Exchange Commission pursuant to the Registrant’s application requesting confidential treatment pursuant to Rule 24b-2 of the
Securities Exchange Act of 1934, as amended. 


  
 23 








 (c) Additional Conditions. As a condition to any such assignment or subletting, whether or
not Sublandlord’s consent is required, Sublandlord may require: 
 (i) that any assignee or subtenant agree, in writing at the time of
such assignment or subletting, that if Sublandlord gives such party notice that a Default of Subtenant has occurred hereunder, such party shall thereafter make all payments otherwise due Subtenant directly to Sublandlord, which payments will be
received by Sublandlord without any liability except to credit such payment against those due under the Sublease, and any such third party shall agree to attorn to Sublandlord or its successors and assigns should this Sublease be terminated for any
reason; provided, however, in no event shall Sublandlord or its successors or assigns be obligated to accept such attornment; and 
 (ii) A
list of Hazardous Materials, certified by the proposed assignee or sublessee to be true and correct, which the proposed assignee or sublessee intends to use, store, handle, treat, generate in or release or dispose of from the Subleased Premises,
together with copies of all documents relating to such use, storage, handling, treatment, generation, release or disposal of Hazardous Materials by the proposed assignee or subtenant in the Subleased Premises or on the Project, prior to the proposed
assignment or subletting, including, without limitation: permits; approvals; reports and correspondence; storage and management plans; plans relating to the installation of any storage tanks to be installed in or under the Project (provided, said
installation of tanks shall only be permitted after Sublandlord has given its written consent to do so, which consent may be withheld in Sublandlord’s sole and absolute discretion); and all closure plans or any other documents required by any
and all federal, state and local Governmental Authorities for any storage tanks installed in, on or under the Project for the closure of any such tanks. Neither Subtenant nor any such proposed assignee or subtenant is required, however, to provide
Sublandlord with any portion(s) of the such documents containing information of a proprietary nature which, in and of themselves, do not contain a reference to any Hazardous Materials or hazardous activities. 

(d) No Release of Subtenant, Sharing of Excess Rents. Notwithstanding any assignment or subletting, Subtenant shall at all times remain
fully and primarily responsible and liable for the payment of Rent and for compliance with all of Subtenant’s other obligations under this Sublease. Except in the case of a Permitted Assignment, if the Rent due and payable by a sublessee or
assignee (or a combination of the rental payable under such sublease or assignment plus any bonus or other consideration therefor or incident thereto in any form) exceeds the sum of the rental payable under this Sublease (excluding however, any Rent
payable under this Section), and actual and reasonable tenant improvement costs, brokerage fees, legal costs, design or construction fees, free rent, lease take-over costs, or other similar concessions actually and reasonably incurred in connection
with the proposed assignment or sublease (“Excess Rent”), then Subtenant shall be bound and obligated to pay Sublandlord as Additional Rent hereunder [***] percent ([***]%) of such Excess Rent within 10 days following receipt
thereof by Subtenant. If Subtenant shall sublet the Subleased Premises or any part thereof, Subtenant hereby immediately and irrevocably assigns to Sublandlord, as security for Subtenant’s obligations under this Sublease, all rent from any such
subletting, and Sublandlord as assignee, or a receiver for Subtenant appointed on Sublandlord’s application, may collect such rent and apply it toward Subtenant’s obligations under this Sublease; except that, until the occurrence of a
Default, Subtenant shall have the right to collect such rent. 

  
 Portions of this
Exhibit, indicated by the mark “[***],” were omitted and have been filed separately with the Securities and Exchange Commission pursuant to the Registrant’s application requesting confidential treatment pursuant to Rule 24b-2 of the
Securities Exchange Act of 1934, as amended. 


  
 24 








 (e) No Waiver. The consent by Sublandlord to an assignment or subletting shall not relieve
Subtenant or any assignees of this Sublease or any sublessees of the Subleased Premises from obtaining the consent of Sublandlord to any further assignment or subletting nor shall it release Subtenant or any assignee or sublessee of Subtenant from
full and primary liability under this Sublease. The acceptance of Rent hereunder, or the acceptance of performance of any other term, covenant, or condition thereof, from any other person or entity shall not be deemed to be a waiver of any of the
provisions of this Sublease or a consent to any subletting, assignment or other transfer of the Subleased Premises. 
 (f) Prior Conduct
of Proposed Transferee. Notwithstanding any other provision of this Section 21, if (i) the proposed assignee or sublessee of Subtenant has been required by any prior Sublandlord, lender or Governmental Authority to take remedial action
in connection with Hazardous Materials contaminating a property, where the contamination resulted from such party’s action or use of the property in question and such party has failed to do so as required, (ii) the proposed assignee or
sublessee is subject to an enforcement order issued by any Governmental Authority which has not been complied with in connection with the use, storage, handling, treatment, generation, release or disposal of Hazardous Materials (including, without
limitation, any order related to the failure to make a required reporting to any Governmental Authority), or (iii) because of the existence of a pre-existing environmental condition in the vicinity of or underlying the Project, the risk that
Sublandlord would be targeted as a responsible party in connection with the remediation of such pre-existing environmental condition would be materially increased or exacerbated by the proposed use of Hazardous Materials by such proposed assignee or
sublessee, Sublandlord shall have the absolute right to refuse to consent to any assignment or subletting to any such party. 
 (g)
Recapture. No failure of Sublandlord to exercise any such option to terminate this Sublease (or to underlet as provided herein), or to deliver a timely notice in response to the Assignment Notice within the applicable time period shall be
deemed to be Sublandlord’s consent to the proposed assignment, sublease or other transfer or otherwise shall be deemed a waiver of Sublandlord’s options as to the Offered Space to the extent provided herein. If Sublandlord elects to
recapture the Offered Space as provided in Section 21(b), Sublandlord may elect to do so either by termination of the Sublease (as to the Offered Space only), or by electing to sub-sublease the Offered Space from Subtenant as follows: 

(i) Sublandlord’s Right to Terminate. Upon receipt of any Assignment Notice in which Subtenant proposes to assign this Sublease
(which shall include, for purposes of this Section 21(g)(i), a proposed subletting of all or substantially all of the Subleased Premises for the entire or substantially the entire remaining Sublease Term), or in which Subtenant proposes to
sublet less than substantially all of the Subleased Premises for a Full Term Third Party Sublease, then and in such event Sublandlord shall have the right, exercisable by notice to Subtenant given within sixty (60) days (which period shall be
reduced to 15 business days in the case of a Specific Assignment Notice) after Sublandlord receives Subtenant’s Assignment Notice and in addition to the other rights 

  
 Portions of this
Exhibit, indicated by the mark “[***],” were omitted and have been filed separately with the Securities and Exchange Commission pursuant to the Registrant’s application requesting confidential treatment pursuant to Rule 24b-2 of the
Securities Exchange Act of 1934, as amended. 


  
 25 








 
granted Sublandlord under this Section 21(g)(i), (x) in the case of an assignment, to terminate this Sublease, in which event this Sublease shall terminate on the Assignment Date,
with the same force and effect as if the Assignment Date were the date originally fixed in this Sublease as the Expiration Date, or (y) in the case of a Full Term Third Party Sublease, to terminate this Sublease solely with respect to Offered
Space, in which event on the Assignment Date, such space shall no longer be part of the Subleased Premises or covered by this Sublease and the rentable area of the Subleased Premises, the Base Rent and Expense Rent shall be appropriately reduced.

 (ii) Sublandlord’s Right to Underlet. Upon receipt of any Assignment Notice in which Subtenant proposes to sublet all or any
part of the Subleased Premises for a Full Term Third Party Sublease, Sublandlord shall have the option with respect to each such Assignment Notice, exercisable by Sublandlord in writing within sixty (60) days (which period shall be reduced to
15 business days in the case of a Specific Assignment Notice) after receipt of such Assignment Notice, to underlet from Subtenant the space which Subtenant so desires to sublet, for the term for which Subtenant desires to sublet it and for a rent
equal to the lower of 
 A. the rent for which Subtenant proposes to sublet such space, as set forth in the Assignment Notice and the
instruments which accompany such notice, or 
 B. the rent which Subtenant by the terms of this Sublease is required to pay for the rentable
area of the space so to be sublet, such underlease to be upon the covenants, agreements, terms, provisions and conditions contained in this Sublease except as hereinafter provided and except for such thereof which are irrelevant or inapplicable.
Without limiting the generality of the foregoing, it is agreed that: 
 (1) such underlease to Sublandlord shall give the undertenant the
unqualified and unrestricted right, without Subtenant’s permission, (x) to assign such underlease or any interest therein and/or to underlet from time to time the space covered by such underlease or any parts of such space for any purpose,
or purposes that the undertenant, in the undertenant’s uncontrolled discretion, shall deem suitable or appropriate, except that Sublandlord agrees that any such underlease will not be assigned except simultaneously with an assignment of
Sublandlord’s interest under this Sublease so that at all times the Sublandlord under this Sublease and the undertenant under said underlease shall be the same person, corporation or other entity, and each assignor of such underlease shall
thereafter be released of all obligations under such underlease, and (y) to make any and all changes, alterations and improvements in the space covered by such underlease deemed desirable by the undertenant; 

(2) such underlease shall provide that any assignee or subtenant of the undertenant may, at the election of the undertenant, be permitted to
make alterations, decorations and installations in such space or any part thereof (subject to the receipt of Landlord’s approval of the same, and Subtenant shall have no obligation of any restoration with respect to any such alterations,
decorations or installations); 

  
 Portions of this
Exhibit, indicated by the mark “[***],” were omitted and have been filed separately with the Securities and Exchange Commission pursuant to the Registrant’s application requesting confidential treatment pursuant to Rule 24b-2 of the
Securities Exchange Act of 1934, as amended. 


  
 26 








 (3) such underlease shall provide that the parties to such underlease expressly negate any
intention that any estate created under such underlease be merged with any other estate held by either of said parties; 
 (4) Subtenant
shall and will at all times at its expense provide and permit an appropriate and lawful means of ingress and egress from such space so underlet by Subtenant to Sublandlord, such means of ingress or egress to be specified by Subtenant in the
Assignment Notice with respect to such space; 
 (5) Sublandlord, at Subtenant’s expense, may make such Alterations as may be required
or deemed necessary by Sublandlord physically to separate the underleased space from the balance of the Subleased Premises and to comply with all laws and requirements of public authorities relating to such separation; 

(6) the occupant or occupants of all or any part or parts of such space shall, in common with Subtenant, have the use of toilet and other
common facilities on the floor on which such space is located; and 
 (7) no default by Sublandlord under such underlease or by anyone
claiming through such underlease shall be deemed to constitute a default under this Sublease. 
 (h) Other Additional Conditions. If
Sublandlord does not exercise any option granted to Sublandlord by Sections 21(g)(i) or 21(g)(ii) with respect to a proposed sublease or assignment which is the subject of an Assignment Notice, Sublandlord agrees that, after Sublandlord’s
receipt of an executed copy of the proposed instrument of sublease or assignment and all other agreements, if any, related to the proposed sublease or assignment, and any other information reasonably requested by Sublandlord, Sublandlord will not

Sublandlord shall submit this Sublease to Landlord. It is expressly understood and agreed that, notwithstanding anything to the contrary contained herein, the Initial Term shall not commence, nor shall Subtenant take possession of the Subleased

consent to any provision hereof, except as expressly provided hereunder or in the Lease. Subject to the foregoing, Sublandlord shall pay all costs or fees charged by or due to Landlord in connection with obtaining the Consent and the SNDA, whether

any and all of the rights and remedies specifically provided for in the Lease, which are incorporated herein and made a part hereof, with the same force and effect as if herein set forth in full, and that wherever in the Lease rights and remedies
are given to Landlord therein named, the same shall be deemed to refer to Sublandlord herein. If Sublandlord shall receive notice from Landlord of any default occurring under the Lease with respect to the Subleased Premises, or if there is a default
by Subtenant hereunder, Sublandlord shall deliver written notice thereof to Subtenant of such default (Subtenant having the same corresponding applicable notice, grace or cure period).
