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 Date” shall be the date which is the earlier to occur of: (i) the twelfth (12th) monthly anniversary of the Commencement Date, and (ii) the date upon which Subtenant occupies [***] ([***]) or more full floors of the Subleased 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.

(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 and other charges herein reserved and payable shall be paid by Subtenant in the manner and to the persons set forth in the statement from Sublandlord describing the amounts due. All Expense Rent, adjustments

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.

(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

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 (1^st) 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 (7^th) 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.

(d) Provided that Subtenant complies with the provisions of Section 8 hereof with respect to the Contraction Space, effective as of the Contraction Date: (i) the definition of Subleased Premises shall be modified to exclude the Contraction Space; (ii) and Base Rent for the remaining Term shall be decreased proportionately to exclude the Contraction Space; (iii) Subtenant’s Pro Rata Share of Parking Spaces in the Garage shall be decreased proportionately; and (iv) Subtenant’s Share in Section 5(a)(i) hereof shall be decreased proportionately to exclude the Contraction Space.

(e) Promptly after the Contraction Date, Sublandlord and Subtenant shall execute a suitable instrument 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.

10. USE OF SUBLEASED PREMISES. (a) Subtenant shall use the Subleased Premises only for the Permitted Use set forth in the Basic Lease Provisions of the Lease and in accordance with Section 7 (Use) of the Lease, and for no other purposes.

(b) Subject to approval by Landlord, any applicable Legal Requirements, and final approval of plans as otherwise provided herein, Sublandlord shall approve the use by Subtenant of a portion of the Floor L1 of the Subleased Premises for use as an auditorium and/or a fitness center, provided the same is not generally open to the public for use or membership.

11. CONDITION OF SUBLEASED PREMISES.

(a) As of the date hereof, Sublandlord represents that it is not aware of any condition within the Premises and/or the Subleased Premises that would materially adversely affect Subtenant’s design, permitting, construction or use of the Subleased Premises including, without limitation, any restrictions on utilities, any exclusive use restrictions or any environmental conditions impacting the Subleased Premises.

15. SUBLANDLORD OBLIGATIONS. (a) Subtenant acknowledges and agrees that, except as expressly provided hereunder, Sublandlord shall have no obligation to provide any services to the Subleased Premises, to fund the Base TI Allowance provided under the Work Letter independent of Landlord’s obligation to provide same to Sublandlord under the terms of the Lease, or to perform the terms, covenants, conditions or obligations of Landlord, as the owner of the Project, contained in the Lease including the preparation of Annual Estimates and Annual Statements of Operating Expenses pursuant to Section 5 (Operating Expense Payments), Section 11 (Utilities and Services; Emergency Generator; Service Interruptions), Section 13 Landlord’s Repairs, Section 17(a) Landlord’s Insurance, 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.

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.

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.

(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.

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 ▇▇▇▇▇’▇ 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.

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.

(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.

(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);

(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.

(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.

(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

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);

(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 unreasonably withhold or delay its consent to such proposed sublease or assignment provided that the terms of the instrument of sublease or assignment conform to the Assignment Notice, the conditions of Section 21(c) above shall be satisfied, and the following further conditions shall be satisfied:

(i) the Subleased Premises or any part thereof shall not, without Sublandlord’s prior consent, have been listed or otherwise publicly advertised for subletting at a rental rate less than the rental rate being sought by Landlord or Sublandlord for space in the Project, and all advertisements of the Subleased Premises or any portion thereof for subletting shall have been approved by Sublandlord. The foregoing, however, shall not be deemed to prohibit Subtenant from negotiating or consummating a sublease at a lower rental rate;

(ii) Subtenant shall not then be in Default under this Sublease with respect to any monetary obligations beyond the time herein provided, if any, to cure such default and shall not otherwise be in Default under this Sublease beyond the time herein provided, if any, to cure such default;

(iii) the proposed subtenant or assignee is engaged in a business or activity, and the Subleased Premises, or the relevant part thereof, will be used in a manner, which (A) is in keeping with the then standards of the 75 Binney Building and the Project and (B) is not prohibited under the Sublease or the Lease;

(iv) if Landlord or Sublandlord has space available for lease or sublease in the Project, the proposed subtenant or assignee shall not then be a person or entity, nor an affiliate of a person or entity, with whom Sublandlord or Landlord, as applicable, is then actively negotiating to lease space in the Building;

(v) the proposed subtenant or assignee is of good reputation with sufficient financial worth considering the responsibility involved, and Sublandlord has been furnished with reasonable evidence of such financial worth and any sublease shall provide that, upon Sublandlord’s request from time to time, the proposed subtenant shall deliver to Sublandlord a copy of subtenant’s most recent financial statements certified by an officer of subtenant;

(vi) any proposed sublease shall state that it is expressly subject to all of the obligations of Subtenant under this Sublease and shall contain the further condition and restriction that the sublease shall not be assigned, encumbered or otherwise transferred or the subleased premises further sublet by the sublessee in whole or in part, or any part thereof suffered or permitted by the sublessee to be used or occupied by others, without the prior written consent of Sublandlord and Landlord in each instance as provided herein;

(vii) any proposed sublease shall provide that it is subject and subordinate to this Sublease and to the matters to which this Sublease is or shall be subordinate, and that in the event of the termination of this Sublease, or the re-entry or dispossession of Subtenant by Sublandlord under this Sublease, such subtenant shall, at Sublandlord’s option, attorn to Sublandlord as its sublessor pursuant to the then applicable terms of such sublease for the remaining term thereof, except that such subtenant shall have no right to use any portion of the Subleased Premises (or other space in the Building occupied or controlled by Subtenant) which is not part of the subleased premises, and Sublandlord shall not be (1) liable for any previous act or omission of Subtenant; (2) subject to any offset or defense which theretofore accrued to such subtenant (including, without limitation, any rights under 11 U.S.C. §365(h)); (3) bound by any rent or other sums paid by such subtenant more than one month in advance; (4) liable for any security deposit not actually received by Sublandlord; (5) liable for any work or payments on account of improvements to the subleased premises or (6) bound by any amendment of such sublease not consented to in writing by Sublandlord;

(viii) no subletting shall be for a term of less than two (2) years (provided, however, that if less than two (2) years remains in the Sublease Term, such sublease may be for the balance of the Sublease Term);

(ix) in no event shall there be more than three (3) occupants including Subtenant on any one floor of the Subleased Premises; and

(x) without the express written consent of Sublandlord, the proposed subtenant or assignee shall not be a person or entity, nor an affiliate of a person or entity, which is engaged in research, development, sale or marketing of drugs for the treatment of cancer.

Subtenant agrees to furnish Sublandlord such information in addition to the information set forth in the Assignment Notice as Sublandlord may reasonably request in connection with the proposed sublease or assignment.

22. CASUALTY AND CONDEMNATION. Notwithstanding anything to the contrary contained in this Sublease or in the Lease, Subtenant shall not have the right to terminate this Sublease as to all or any part of the Subleased Premises, or be entitled to an abatement of Base Rent, Expense Rent, Parking Charges, Subtenant Surcharges, additional rent or any other item of rental, by reason of a casualty or condemnation affecting the Subleased Premises unless Sublandlord is entitled to terminate the Lease or is entitled to a corresponding abatement with respect to its corresponding obligation under the Lease. If Sublandlord is entitled to terminate the Lease for all or any portion of the Subleased Premises by reason of casualty or condemnation, Subtenant may terminate this Sublease as to any corresponding part of the Subleased Premises by written notice to Sublandlord given at least two (2) business days prior to the date(s) Sublandlord is required to give notice to Landlord of such termination under the terms of the Section 18 (Restoration) of the Lease.

23. CONSENTS. In no event shall Sublandlord be liable for failure to give its consent or approval in any situation where consent or approval has been withheld or refused by Landlord, whether or not such withholding or refusal was proper. Sublandlord shall diligently pursue any reasonable request for Landlord consents or approvals required hereunder and upon request of Subtenant shall appeal any unreasonable withholding of approval or refusal of consent by Landlord. Any consent required of Sublandlord under this Sublease shall not be withheld or unreasonably conditioned or delayed if approved by Landlord pursuant to the terms and conditions of this Sublease and the Consent.

24. CONDITIONS; CONSENT OF LANDLORD; SNDA.

(a) Subtenant hereby acknowledges and agrees that this Sublease is subject to and conditioned upon Sublandlord obtaining the written consent (including recognition of this Sublease) (the “Consent”) of Landlord as provided in the Lease, which Consent shall be substantially on the terms and conditions set forth in the attached Exhibit “F”/Landlord’s Consent, acceptable to each of Subtenant and Sublandlord in its sole discretion.

(b) Subtenant and Sublandlord hereby acknowledge and agree that this Sublease is subject to and conditioned upon Sublandlord obtaining a subordination, non-disturbance and attornment agreement (“SNDA”), in substantially the form attached to the Lease as Exhibit “I”, from the Holder of any Mortgage (as such terms are defined in the Lease) in accordance with the terms and provisions of Section 27 (Subordination) of the Lease acceptable to each of Sublandlord and Subtenant in its sole discretion.

(c) Promptly following the execution and delivery of this Sublease by Sublandlord and Subtenant, 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 Premises or any part thereof, until the Consent and the SNDA have been obtained. Subtenant hereby agrees that it shall cooperate in good faith with Sublandlord and shall comply with any reasonable requests made of Subtenant by Sublandlord or Landlord in the procurement of the Consent and the SNDA. In no event shall either Sublandlord or Subtenant be obligated to make any payment to Landlord or to the Holder of any Mortgage in order to obtain the Consent, the SNDA or Landlord’s 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 pursuant to the Lease or otherwise.

(d) In the event Landlord does not give its written Consent to this Sublease or the Holder of any Mortgage does not deliver its SNDA as aforesaid, in each instance on or before July 31, 2015 (the “Notice and SNDA Delivery Date”), then, at the option of Subtenant upon written notice delivered to the Sublandlord following such Notice and SNDA Delivery Date, this Sublease shall not become effective, and there shall be no further obligation of the parties, unless within thirty (30) additional days following the giving of any such notice the Consent and the SNDA shall have been executed and delivered.

(e) In the event Landlord does not give its written Consent to this Sublease or the Holder of any Mortgage does not deliver its SNDA as aforesaid, in each instance on or before August 31, 2015 (the “Outside Notice and SNDA Delivery Date”), then, at the option of Subtenant or Sublandlord and upon written notice delivered to the other following such Outside Notice and SNDA Delivery Date, this Sublease shall not become effective, and there shall be no further obligation of the parties, unless within thirty (30) additional days following the giving of any such notice the Consent and the SNDA shall have been executed and delivered.

25. DEFAULTS. Subtenant covenants and agrees that in the event that it shall default in the performance of any of the terms, covenants and conditions of this Sublease or of the Lease, beyond the expiration of any applicable notice, grace or cure period as provided in the Lease with the same force and effect as if herein set forth in full (each, a “Default”), Sublandlord shall be entitled to exercise any and all of the rights and remedies to which it is entitled by law, including, without limitation, the remedy of summary proceeding, and also 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).

26. NOTICE. Whenever, by the terms of this Sublease, any notice, demand, request, approval, consent or other communication (each of which shall be referred to as a “notice”) shall or may be given either to Sublandlord or to Subtenant, such notice shall be in writing and shall be sent by hand delivery, reputable overnight courier, or by registered or certified mail, return receipt requested, postage prepaid, addressed as follows (or to such other address or addresses as may from time to time hereafter be designated by Sublandlord or Subtenant, as the case may be, by like notice):

F-4

ASSUMPTION; TERMINATION OF THE LEASE, ETC. NOTWITHSTANDING ANYTHING IN THE SUBLEASE TO THE CONTRARY:

(b)

Landlord, Tenant and Subtenant agree to each of the terms and conditions of this Consent, and upon any conflict between the terms of the Lease or the Sublease and this Consent, the terms of this Consent shall control.

(c)

The Sublease shall be deemed and agreed to be a sublease only, and not an assignment, and there shall be no further subletting or assignment of all or any portion of the Premises demised under the Lease (including the Subleased Premises demised by the Sublease) except in accordance with the terms and conditions of the Lease.

(d)

If Landlord terminates the Lease as a result of a default by Tenant, thereunder, or if the Lease terminates for any other reason (other than as a result of a default of Subtenant under the Sublease), then the Sublease shall automatically and without any further action required by Landlord or by Subtenant become and be deemed to be a direct lease between Landlord and Subtenant upon all of the terms and conditions set forth in the Sublease, except as follows:

than one (1) month’s rent or for any security deposit paid by Subtenant (except to the extent actually delivered to Landlord), (ii) be liable for any prior act or omission of Tenant under the Lease prior to the date of Lease termination or for any other defaults of Tenant under the Sublease prior to the date of Lease termination, (iii) except to the extent of any unpaid portion of the Base TI Allowance due or payable pursuant to the terms of the Work Letter, and except for any valid rights of offset under Sections 11(d), 18, 19, 31(b) and/or 31(c), be subject to any defenses or offsets previously accrued which Subtenant may have against Tenant for any period prior to the date of Lease termination, or (iv) be bound by any changes or modifications made to the Sublease without the prior written consent of Landlord.

(e)

Tenant agrees to reimburse all of Landlord’s costs and expenses in connection with this Consent.
