The Existing Leases shall terminate at the close of the day on the day immediately preceding the Commencement Date (the “Existing Lease Termination Date”) as if the Existing Lease Termination Date was the expiration date of the Existing Leases and shall be superseded by this Lease, except that any obligations or liabilities, including indemnification obligations, that expressly survive the expiration or termination of the Existing Leases shall survive such termination as provided in the Existing Leases.

Section 2.2 Appurtenant Rights.

ACTIVE/103568117.9

The Tenant shall have, as appurtenant to the Premises, the nonexclusive right to use in common with others, subject to reasonable rules of general applicability to occupants of the Building from time to time made by the Landlord of which the Tenant is given notice; (i) the office entry, office vestibules and office lobby of the Building, first floor mailroom, the common stairways, elevators, elevator ▇▇▇▇▇, boiler room, elevator rooms, sprinkler rooms, mechanical rooms, electric and telephone closets, janitor closets, loading docks and bays, rooftop mechanical penthouses to the extent they house Building equipment, and the pipes, sprinklers, ducts, conduits, wires and appurtenant fixtures and equipment serving the Premises in common with others, (ii) common walkways and driveways necessary or reasonably convenient for access to the Building, (iii) access to loading area and freight elevator subject to Landlord’s reasonable rules and regulations in effect from time to time and applicable to all occupants of-the Building and of which the Tenant is given notice, (iv) if the Premises at any time include less than the entire rentable floor area of any floor, the common toilets, corridors, vestibules, and elevator lobby of such floor, and (v) such other common areas and facilities of the Building and the Land necessary for access to or beneficial use of the Premises. Under the Existing Leases, Tenant has installed equipment on the roof of the Building (“Roof Equipment”) in the locations marked on Exhibit F attached hereto (the “Tenant Roof Areas”). Subject to compliance with all applicable Legal Requirements, Landlord hereby approves and consents to Tenant’s continued use of the roof in the Tenant Roof Areas for the operation, maintenance and replacement of Tenant’s existing Roof Equipment, provided, however, Tenant’s use of and access to the roof and Tenant’s operation of the Roof Equipment shall be subject to Tenant’s obligations under the Lease, including, without limitation, Tenant’s repair and maintenance and insurance and indemnification obligations under the Lease.

Section 2.3 Landlord’s Reservations.

The Landlord reserves the right from time to time, at reasonable times and upon prior written notice to Tenant (except in emergency situations), without unreasonable interference with the Tenant’s use: (i) to install, use, maintain, repair, replace and relocate for service to the Premises and/or other parts of the Building, pipes, ducts, conduits, wires and appurtenant fixtures and equipment, wherever located in the Premises or the Building, and (ii) to alter or relocate any other common facility, provided that substitutions are substantially equivalent or better.

Section 2.4 Parking.

The Landlord shall operate, or cause to be operated, a parking garage known as the ▇▇ ▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇ Garage (the “Garage”) to serve the Building and other buildings in University Park. The Tenant’s parking privileges shall be initially located in the Garage and shall be on a nonexclusive basis (i.e., no reserved spaces); provided, however, Landlord agrees that the Garage shall be operated so as to maintain therein sufficient spaces to accommodate Tenant’s parking privileges

ACTIVE/103568117.9

described in Exhibit A. However, Tenant’s parking privileges may be relocated by Landlord, upon reasonable prior notice to Tenant from Landlord, to another parking garage within University Park. All monthly users will have unlimited access to the Garage twentyfour (24) hours per day, seven days per week.

The Tenant agrees that it and all persons claiming by, through and under it, shall at all times abide by the reasonable rules and regulations promulgated by the Landlord, of which Tenant is given written notice, with respect to the use of the parking facilities provided by the Landlord pursuant to this Lease. If there are any conflicts between the provisions of such rules and regulations and any provisions of this Lease, the provisions of this Lease shall govern.

Charges for Tenant’s parking privileges hereunder shall be at the current monthly rate applicable for such spaces and shall constitute Additional Rent and shall be payable monthly to Landlord, during the Term, from and after the Commencement Date at the time and in the fashion in which Annual Fixed Rent under this Lease is payable.

At any time during the Term Landlord shall have the right to assign Landlord’s obligations to provide parking, as herein set forth, together with Landlord’s right to receive Additional Rent for such parking spaces as herein provided, to a separate entity created for the purpose of providing the parking privileges set forth herein. In such event, Landlord and Tenant agree to execute and deliver appropriate documentation, including documentation with the new entity, reasonably necessary to provide for the new entity to assume Landlord’s obligations to provide the parking privileges to Tenant as specified herein and for the Tenant to pay the Additional Rent attributable to the parking privileges directly to the new entity.

Notwithstanding the foregoing, any failure of such assignee to provide to Tenant the parking privileges set forth herein shall be a Landlord default under this Lease.

Section 2.5 Commencement Date.

“Commencement Date” shall be the Effective Date of this Lease.

Section 2.6 Extension Option.

Provided that there has been no Event of Default which is uncured and continuing on the part of the Tenant and the Tenant is, as of the date of exercise and as of the commencement date of the Extension Term (as such term is defined below), actually occupying sixty percent (60%) or more of the Premises for its own business purposes, the Tenant shall have the right to extend the Term hereof for one (1) additional period of five (5) years (the “Extension Term”).

ARTICLE I.Such right to extend the Term shall be exercised by the giving of notice by Tenant to Landlord at least nine (9) months prior to the expiration of the then current Term. Upon the giving of such notice, this Lease and the Term hereof shall be extended for an additional term of five (5)years without the necessity for the execution of any additional documents except a document evidencing the Annual Fixed Rent for the Extension Term to be

ACTIVE/103568117.9

determined as set forth below. Time shall be of the essence with respect to the Tenant’s giving notice to extend the Term.

(1)The Extension Term shall be upon all the terms, conditions and provisions of this Lease except the Annual Fixed Rent during such five (5) year Extension Term shall be the then Extension Fair Rental Value of the Premises for such Extension Term to be determined under this Section 2.6.

(2)For purposes of the Extension Term described in this Section 2.6, the “Extension Fair Rental Value” of the Premises shall mean the then current fair market annual rent for leases of other space similarly improved in the commercial markets that surround the MIT campus (East Cambridge/▇▇▇▇▇▇▇ Square/Cambridgeport), taking into account the condition to which such premises, have been improved (excluding Tenant Removable Property) and the economic terms and conditions specified in this Lease that will be applicable thereto, including the savings, if any, due to the absence or reduction of brokerage commissions. The Landlord and Tenant shall endeavor to agree upon the Extension Fair Rental Value of the Premises within thirty (30) days after the Tenant has exercised the option for the Extension Term. If the Extension Fair Rental Value of the Premises is not agreed upon by the Landlord and the Tenant within this time frame, each of the Landlord and the Tenant shall retain a real estate professional with at least ten (10) years continuous experience in the business of appraising or marketing (including brokering) similar commercial real estate in the Cambridge, Massachusetts area who shall, within thirty (30) days of his or her selection, prepare a written report summarizing his or her conclusion as to the Extension Fair Rental Value. The Landlord and the Tenant shall simultaneously exchange such reports; provided, however, if either party has not obtained such a report within fortyfive (45) days after the last day of the thirty (30) day period referred to above in this Section 2.6, then the determination set forth in the other party’s report shall be final and binding upon the parties. If both parties receive reports within such time and the lower determination is within ten percent (10%) of the higher determination, then the average of these determinations shall be deemed to be the Extension Fair Rental Value for the Premises. If these determinations differ by more than ten percent (10%), then the Landlord and the Tenant shall mutually select a person with the qualifications stated above (the “Final Professional”) to resolve the dispute as to the Extension Fair Rental Value for the Premises. If the Landlord and the Tenant cannot agree upon the designation of the Final Professional within ten (10) days of the exchange of the first valuation reports, either party may apply to the American Arbitration Association, the Greater Boston Real Estate Board, or any successor thereto, for the designation of a Final Professional. Within ten (10) days of the selection of the Final Professional, the Landlord and the Tenant shall each submit to the Final Professional a copy of their respective real estate professional’s determination of the Extension Fair Rental Value for the Premises. The Final Professional shall then, within thirty (30) days of his or her selection, prepare a written report summarizing his or her conclusion as to the Extension Fair Rental Value (the “Final Professional’s Valuation”). The Final Professional shall give notice of the Final Professional’s Valuation to the Landlord and the Tenant and such decision shall be final and binding upon the Landlord and the

ACTIVE/103568117.9

Tenant. Each party shall pay the fees and expenses of its real estate professional and counsel, if any, in connection with any proceeding under this paragraph, and one-half of the fees and expenses of the Final Professional. In the event that the commencement of the Extension Term occurs prior to a final determination of the Extension Term Fair Rental Value therefor (the “Extension Rent Determination Date”), then the Tenant shall pay the Annual Fixed Rent at the then applicable Fixed Rental Rate (such amount being referred to as the “Interim Rent”). If the Annual Fixed Rent as finally determined for the Extension Term is determined to be greater than the Interim Rent, then the Tenant shall pay to the Landlord the amount of the underpayment for the period from the end of the initial term of this Lease until the Extension Rent Determination Date within thirty (30) days of the Extension Rent Determination Date. If the Annual Fixed Rent as finally determined for the Extension Term is determined to be less than the Interim Rent, then the Landlord shall credit the amount of such overpayment against the monthly installments of Annual Fixed Rent coming due after the Extension Rent Determination Date.

Section 2.7 Right of First Offer.

Landlord hereby grants to Tenant during the Term a right of first offer (“ROFO”) to lease any leaseable space in the Building that becomes Available to lease (the “ROFO Space”) on the terms set forth below. “Available” means that the ROFO space is vacant and free of any present or future possessory right now or, to the extent specified in clause (ii) of the following sentence, hereafter existing in favor of any third party. Anything to the contrary contained herein notwithstanding, Tenant’s ROFO is subordinate to (i) any right of offer, right of first refusal, renewal right or similar right or option in favor of any third party existing as of the date of this Lease, and (ii) Landlord’s right to (x) extend the term of lease of any now or then existing tenant or occupant, or such tenant’s or occupant’s affiliate or successor or (y) enter into a new lease with any now or then existing tenant or occupant, or such tenant’s or occupant’s affiliate or successor, whether or not pursuant to an option to renew. Landlord represents that the only tenant in the Building with superior rights to any ROFO Space pursuant to clause (i) above is Agios Pharmaceuticals, Inc., together with its successors and assigns (such superior right being a right of expansion and extension only). At or before such time as Landlord has decided to commence the marketing of the ROFO Space in anticipation of such space becoming Available, Landlord shall deliver a written notice to Tenant (the “ROFO Notice”) setting forth the basic business terms on which the ROFO Space is to be marketed. Tenant shall have fifteen (15) days after it has received the ROFO Notice within which to reply to Landlord in writing of its election to lease the ROFO Space upon the terms and conditions in the ROFO Notice (time being of the essence with respect to the giving of such notice by Tenant to Landlord). Tenant shall not have the option to include in the Premises less than the entire ROFO Space described in the ROFO Notice. If Tenant accepts Landlord’s offer, then upon the date on which Landlord delivers vacant possession of the ROFO Space to Tenant the ROFO Space shall become part of the Premises upon the terms set forth in the ROFO Notice and otherwise upon all of the terms and conditions of this Lease. Promptly after any such election by Tenant, Landlord and Tenant shall confirm the occurrence thereof and the inclusion of the ROFO Space in the Premises as aforesaid by executing an amendment to this Lease in form and substance reasonably satisfactory to

ACTIVE/103568117.9

Landlord and Tenant; provided, that failure by Landlord or Tenant to execute the same shall not affect the inclusion of the ROFO Space in the Premises in accordance with this Section 2.7.

If Tenant refuses the ROFO Space or fails to respond to Landlord’s ROFO Notice within such 15day period, then (i) Landlord may enter into one or more leases of the applicable ROFO Space with third parties on such terms and conditions as Landlord shall determine, and (ii) the ROFO with respect to such ROFO Space shall be null and void and of no further force and effect; provided, however, that Landlord shall not enter into any such lease on “terms and conditions more favorable to a prospective tenant” without first re-offering such ROFO Space to Tenant as hereinafter provided. As used herein, “terms and conditions not more favorable to a prospective tenant” shall mean total rent of ninetytwo and one-half percent (92.5%) or less than the total rent stated in the ROFO Notice for the ROFO Space and under similar other terms and conditions as proposed in the ROFO Notice. If Landlord wishes to lease the ROFO Space on terms and conditions more favorable to a prospective tenant, Landlord shall first re-offer the ROFO Space to Tenant on such more favorable terms and conditions in accordance the procedures set forth in the first paragraph of this Section 2.7 (“Additional ROFO Notice”). Tenant shall have one and only one further right to exercise such ROFO pursuant to and in accordance with the terms of this Section but must make such election within five (5) days after it has received the Additional ROFO Notice (time being of the essence with respect to the giving of such notice by Tenant to Landlord).

ARTICLE III

Section 3.2 Real Estate Taxes.

From and after the Commencement Date, during the Term, the Tenant shall pay to the Landlord, as Additional Rent, the Tenant’s Tax Expenses Allocable to the Premises (as such term is hereinafter defined) in accordance with this Section 3.2. The following terms shall have the meanings indicated or referred to below:

(3)“Tax Year” means the 12month period beginning July 1 each year or if the appropriate governmental tax fiscal period shall begin on any date other than July 1, such other date.

(4)“Tenant’s Tax Expense Allocable to the Premises” means that portion of the Landlord’s Tax Expenses for a Tax Year which bears the same proportion thereto as the rentable floor area of the Premises (from time to time) bears to the total rentable floor area of the Building; provided, however, in the event that retail space in the Building is valued by the assessing authorities differently than the office space in the Building due solely on the basis of its use as retail space, the Tenant’s Tax Expense Allocable to the Premises with respect to any Tax Year will be adjusted as is appropriate so that the Tenant is responsible for the portion of the Real Estate Taxes which are properly allocable to the Premises, a reasonably determined by Landlord based on information with respect to the assessment process made available by the assessing authorities.

(5)“The Landlord’s Tax Expenses” with respect to any Tax Year means the aggregate Real Estate Taxes on the Property with respect to that Tax Year, reduced by any abatement or other tax refunds or credits received with respect to that Tax Year, plus any fees paid to third party consultants used by Landlord in connection with the calculation, abatement or refunding of Real Estate Taxes.

(6)“Real Estate Taxes” means (i) all taxes and special assessments of every kind and nature assessed by any governmental authority on the Property; and (ii) reasonable expenses of any proceedings for abatement of such taxes or special assessments. Any special assessments to be included within the definition of “Real Estate Taxes” for any Tax Year shall be limited to the amount of the installment (plus any interest thereon) of such special assessment (which shall be payable over the longest period permitted by law) required to be paid during such Tax Year. There shall be excluded from Real Estate Taxes all income, estate, succession, inheritance, excess profit, franchise and transfer taxes; provided, however, that if at any time during the Term the present system of ad valorem taxation of real property shall be changed so that in lieu of the whole or any part of the ad valorem tax on real property, there shall be assessed on the Landlord a capital levy or other tax on the gross rents received with respect to the Property, or a federal, state, county, municipal or other local income, franchise, excise or similar tax, assessment, levy or charge (distinct from any now in effect) based, in whole or in part, upon any such gross rents, then any and all of such taxes, assessments, levies or charges, to the extent so based, shall be deemed to be included within the term “Real Estate Taxes.”

Payments by the Tenant on account of the Tenant’s Tax Expenses Allocable to the Premises shall be made monthly at the time and in the fashion herein provided for the payment of Annual Fixed Rent and shall be in the amount of onetwelfth (1/12) of the Tenant’s Tax Expenses Allocable to the Premises for the current Tax Year as reasonably estimated by the Landlord.

Not later than one hundred twenty (120) days after the end of each Tax Year, the Landlord shall render the Tenant a statement in reasonable detail showing for the preceding Tax Year or fraction thereof, as the case may be, Real Estate Taxes for such Tax Year, and any abatements or refunds of such Real Estate Taxes. Expenses incurred in obtaining any tax abatement or refund may be charged against such tax abatement or refund before the adjustments are made for the Tax Year. If at the time such statement is rendered it is determined with respect to any Tax Year, that the Tenant has paid (i) less than the Tenant’s Tax Expenses Allocable to the Premises or (ii) more than the Tenant’s Tax Expenses Allocable to the Premises, then, in the case of clause “(i)” the Tenant shall pay to the Landlord, as Additional Rent, within thirty (30) days of such statement the amount of such underpayment and, in the case of clause “(ii)” the Landlord shall credit the amount of such overpayment against the next monthly installments of the Tenant’s Tax Expenses Allocable to the Premises next thereafter coming due (or refund such overpayment if the Term has expired or earlier terminated within thirty (30) days after such expiration or termination).

To the extent that Real Estate Taxes shall be payable to the taxing authority in installments with respect to periods other than a Tax Year, the statement to be furnished by the Landlord shall be rendered and payments made on account of such installments. Notwithstanding the foregoing provisions, no decrease in Landlord’s Tax Expenses with respect to any Tax Year shall result in a reduction of the amount otherwise payable by Tenant if and to the extent any such decrease is attributed by the assessing authority solely to the vacant space in the Building based on information with respect to the assessment process made available by the assessing authorities to Landlord; provided, however, that in no event shall Landlord collect and retain more than one hundred percent (100%) of the Landlord’s Tax Expenses for the Property.

Section 3.3 Operating Expenses.

ACTIVE/103568117.9

been incurred if all of the rentable area in the Building were occupied and were supplied with the same level of standard services as supplied to the Tenant under this Lease. Additionally, if certain services or facilities supplied under this Lease by Landlord do not from time to time, in Landlord’s reasonable judgment, serve all of the users in the Building (i.e.. office, retail, banking, restaurant, etc.), then the costs associated therewith shall be equitably allocated by Landlord, in its reasonable judgment, exclusively or proportionately to and among only those portions of the total rentable floor area of the Building that are benefiting from such services or facilities.

Payments by the Tenant on account of Tenant’s Operating Expenses Allocable to the Premises shall be made monthly at the time and in the fashion herein provided for the payment of Annual Fixed Rent. The amount so to be paid to the Landlord shall be an amount from time to time reasonably estimated by the Landlord to be sufficient to aggregate a sum equal to the Tenant’s share of the Operating Expenses for the Property for each fiscal year of Landlord.

Not later than ninety (90) days after the end of each fiscal year of Landlord or fraction thereof during the Term or fraction thereof at the end of the Term, the Landlord shall render the Tenant a statement (“Landlord’s Statement”) in reasonable detail and according to usual accounting practices certified by a representative of the Landlord, showing for the preceding

ACTIVE/103568117.9

fiscal year of Landlord or fraction thereof, as the case may be, the Operating Expenses for the Property and the Tenant’s Operating Expenses Allocable to the Premises. Said statement to be rendered to the Tenant also shall show for the preceding fiscal year of Landlord or fraction thereof, as the case may be, the amounts of Operating Expenses already paid by the Tenant. If at the time such statement is rendered it is determined with respect to any fiscal year, that the Tenant has paid (i) less than the Tenant’s Operating Expenses Allocable to the Premises or (ii) more than the Tenant’s Operating Expenses Allocable to the Premises, then, in the case of clause “(i)” the Tenant shall pay to the Landlord, as Additional Rent, within thirty (30) days of such statement the amounts of such underpayment and, in the case of clause “(ii)” the Landlord shall credit the amount of such overpayment against the next monthly installment of the Tenant’s Additional Rent (or refund such overpayment if the Term has expired or earlier terminated within thirty (30) days after such expiration or termination).

Section 3.4 Other Utility Charges.

During the Term, the Tenant shall pay directly to the provider of the service all separately metered charges for electrical service in the Premises (including, but not limited to, lights, electrical outlets, VAV boxes and any other special equipment exclusively servicing the Premises, whether located within or outside of the Premises), and shall pay to Landlord as Additional Rent its allocable share of the actual costs charged to Landlord by the providers of water, sewer and other services and utilities which are based on submetered usage.

Section 3.5 Above-standard Services.

If the Tenant requests and the Landlord elects to provide any services to the Tenant in addition to those described in Exhibit D, the Tenant shall pay to the Landlord, as Additional Rent, the amount billed by Landlord for such services at Landlord’s rates as are from time to time in effect, which rates shall reflect the actual cost to Landlord of providing such services, including reasonable actual out-of-pocket costs to third parties and reasonable costs associated with the use of internal staff of either Landlord or affiliated entities of Landlord (but only to the extent such costs are not included in Operating Expenses by Landlord). If the Tenant has requested that such services be provided on a regular basis, the Tenant shall, if requested by the Landlord, pay for such services at the time and in the fashion in which Annual Fixed Rent under this Lease is payable. Otherwise, the Tenant shall pay for such additional services within thirty (30) days after receipt of an invoice from the Landlord. Landlord shall have the right from time to time to inspect Tenant’s utility meters and to install timers or submeters thereon for purposes of monitoring above-standard service usage.

Section 3.6 No Offsets.

Annual Fixed Rent and Additional Rent shall be paid by the Tenant without offset, abatement or deduction except as specifically permitted herein.

Section 3.7 Tenant’s Audit Right.

ACTIVE/103568117.9

Landlord agrees to make its books and records relating to the Operating Expenses for the Property and the Landlord’s Tax Expenses available for examination during normal business hours at Landlord’s principal office in Cleveland, Ohio upon reasonable notice by Tenant; provided that any such examination or audit shall be by an employee of Tenant or an accounting firm or property management firm the fees of which are not determined on a contingency fee basis (as applicable, the “Examiner”), and such examination shall be at Tenant’s sole cost and expense and may be conducted only if a written notice is sent by Tenant requesting the same not later than ninety (90) days following delivery of Landlord’s Statement. In making such examination, Tenant agrees, and shall cause its designated Examiner to agree, to keep confidential any and all information contained in such books and records and any dispute or settlement between Landlord and Tenant arising out of such examination.

If the parties agree or it is finally determined that a discrepancy which involves an overcharge of Tenant’s Operating Expenses Allocable to the Premises or the Tenant’s Tax Expense Allocable to the Premises for the period covered by such Landlord’s Statement, Landlord shall provide Tenant with a credit against the next installment(s) of Tenant’s Additional Rent in the amount of the overpayment by Tenant. If such discrepancy as so agreed upon or determined involves an overcharge to Tenant of more than five percent (5%) in the aggregate for such year, then Landlord shall be responsible for the reasonable hourly fees of the accounting firm or auditing firm conducting the audit.

ARTICLE IV

ALTERATIONS

Section 4.1 Consent Required for Tenant’s Alterations.

The Tenant may make interior alterations and additions of a decorative or cosmetic nature (as defined below), the cost of which does not exceed $50,000 in the aggregate in any twelve (12) month period, without the need of any approval from Landlord but after not less than ten (10) days prior written notice and evidence of insurance for such alterations has been delivered to Landlord (“Cosmetic Alterations”). The Tenant shall not make alterations or additions to the Premises except in accordance with the University Park Tenant Design and Construction Manual from time to time in effect and the plans and specifications therefor first approved by the Landlord, which approval shall not be unreasonably withheld, conditioned or delayed. Tenant shall be responsible for Landlord’s reasonable out-of-pocket costs for any third party architectural, engineering or other consulting services reasonably required by Landlord in connection with Landlord’s review and approval of Tenant’s plans and specifications. The Landlord shall not be deemed unreasonable for withholding approval of any alterations or additions which (i) would adversely affect any structural or exterior element of the Building, any area or element outside of the Premises, or any facility serving any area of the Building outside of the Premises or any publicly accessible major interior features of the Building, (ii) will require unusual expense to readapt the Premises to normal use unless the Tenant first gives assurance reasonably acceptable to the Landlord that such readaptation will be made prior to the expiration of the Term without expense to the Landlord, or (iii) which would not be compatible

ACTIVE/103568117.9

with existing mechanical or electrical, plumbing, HVAC or other systems in the Building, or use more than Tenant’s prorata share of Building capacities, in each case, as reasonably determined by the Landlord.

Section 4.2 Ownership of Alterations.

All alterations and additions (including any alterations, installations, equipment and systems identified on Exhibit G attached hereto as “Landlord Retained Property”) shall become part of the Building and owned by the Landlord except for the items listed as “Tenant Removable Property” on Exhibit G, as such Exhibit G may be amended upon the written agreement of Landlord and Tenant. The Tenant Removable Property shall be removed by Tenant upon the expiration or earlier termination of this Lease. If Tenant fails to inform Landlord, in writing, at least ten (10) days prior to the installation of the alteration or addition, thereby preventing Landlord from making a determination as to whether it will want such addition or alteration removed from the Premises prior to its installation, then Landlord may require such removal without exception. All movable equipment and furnishings not attached to the Premises shall remain the property of the Tenant and shall be removed by the Tenant upon termination or expiration of this Lease. The Tenant shall repair any damage caused by the removal of any alterations, additions or personal property from the Premises, including the Tenant Removable Property.

All construction work by the Tenant shall be done in a good and workmanlike manner employing only firstclass materials and in compliance with Landlord’s construction rules and regulations then in effect and with all applicable laws and all lawful ordinances, regulations and orders of governmental authority and insurers of the Building. The Landlord or Landlord’s authorized agent may (but without any implied obligation to do so) inspect the work of the Tenant at reasonable times and shall give notice of observed defects. All of the Tenant’s alterations and additions and installation of furnishings shall be coordinated with any work being performed by the Landlord and in such manner as to maintain harmonious labor relations and not to damage the Building or interfere with Building construction or operation and, except for installation of furnishings, shall be performed by contractors or workmen first approved by the Landlord, which approval the Landlord agrees not to unreasonably withhold or delay. The Tenant, before starting any work, shall receive and comply with the University Park Tenant Design and Construction Manual from time to time in effect and any of Landlord’s other construction rules and regulations for the Building and shall cause Tenant’s contractors to comply therewith, shall secure all licenses and permits necessary therefor, shall deliver to the Landlord a statement of the names of all its contractors and subcontractors and the estimated cost of all labor and material to be furnished by them, and shall deliver to Landlord security satisfactory to the Landlord protecting the Landlord against liens arising out of the furnishing of such labor and material; and cause each contractor to carry worker’s compensation insurance in statutory amounts covering all the contractors’ and subcontractors’ employees and comprehensive general public liability insurance with such limits as the Landlord may require reasonably, but in no event less than $5,000,000 (per occurrence)/$10,000,000 (general

ACTIVE/103568117.9

aggregate) or in such other amounts as Landlord may reasonably require covering personal injury and death and property damage (all such insurance to be written in companies approved reasonably by the Landlord and insuring the Landlord, Landlord’s managing agent, ground lessor and first mortgagee, and the Tenant as well as the contractors and to contain a requirement for at least thirty (30) days’ notice to the Landlord prior to cancellation, nonrenewal or material change), and to deliver to the Landlord certificates of all such insurance.

Section 4.4 Payment for Tenant Alterations.

The Tenant agrees to pay promptly when due the entire cost of any work done on the Premises by the Tenant, its agents, employees or independent contractors, and not to cause or permit any liens for labor or materials performed or furnished in connection therewith to attach to the Premises or the Property and promptly to discharge any such liens which may so attach.

If any such lien shall be filed against the Premises or the Property as a result of any work done on the Premises by Tenant, its agents, employees or independent contractors, and the Tenant shall fail to cause such lien to be discharged within ten (10) days after the filing thereof, the Landlord may cause such lien to be discharged by payment, bond or otherwise without investigation as to the validity thereof or as to any offsets or defenses which the Tenant may have with respect to the amount claimed. The Tenant shall reimburse the Landlord, as Additional Rent, for any reasonable cost so incurred and shall indemnify and hold harmless the Landlord from and against any and all claims, costs, damages, liabilities and expenses (including reasonable attorneys’ fees) which may be incurred or suffered by the Landlord by reason of any such lien or its discharge.

this Lease, such requirements do not unreasonably interfere with Tenant’s use of the Premises. Except as otherwise provided in this Lease. Landlord’s costs in performing the obligations contained in this Section 5.1 shall be reimbursed by the Tenant to the extent provided in Section 3.3.

Landlord covenants that it shall use reasonable efforts to operate, clean, repair, maintain and manage the Property efficiently and economically.

The Landlord shall not be liable to the Tenant for any compensation or reduction of rent by reason or inconvenience or annoyance or for loss of business arising from the necessity of the Landlord or its agents entering the Premises in accordance with Section 2.3 hereof for any purposes authorized in this Lease, or for repairing the Premises as required or permitted herein or any portion of the Building. In case the Landlord is prevented or delayed from making any repairs, alterations or improvements, or furnishing any services or performing any other covenant or duty to be performed on the Landlord’s part, by reason of any External Cause, the Landlord shall not be liable to the Tenant therefor, nor, except as expressly otherwise provided in this Lease, shall the Tenant be entitled to any abatement or reduction of rent by reason thereof, nor shall the same give rise to a claim in the Tenant’s favor that such failure constitutes actual or constructive, total or partial, eviction from the Premises provided, however, Landlord shall use reasonable, good faith efforts not to interfere with Tenant’s conduct of its business on the Premises.

ACTIVE/103568117.9

The Landlord reserves the right to stop any service or utility system when necessary by reason of accident or emergency, until necessary repairs have been completed; provided, however, that in each instance of stoppage, the Landlord shall exercise diligent efforts to eliminate the cause thereof. Except in case of emergency repairs, the Landlord will give the Tenant reasonable advance notice of any contemplated stoppage and will use diligent efforts to avoid unnecessary inconvenience to the Tenant by reason thereof. In no event shall the Landlord have any liability to the Tenant for the unavailability of heat, light or any utility or service to be provided by the Landlord to the extent that such unavailability is caused by External Causes, provided, however, that the Landlord is obligated to exercise diligent efforts to restore the services or utility systems’ operation.

Notwithstanding anything contained herein to the contrary, in the event Landlord shall fail to provide the services it is required to provide to Tenant pursuant to Exhibit D (a “Service Failure”) other than as a result of Tenant’s acts or omissions or External Causes or as a result of a casualty or condemnation (which events shall be governed solely by Article VIII), and as a result thereof, Tenant is reasonably unable to use or conduct its operations on part or all of the Premises for more than three (3) business days, Tenant shall be entitled to proportionate abatement of rent for the period Tenant is reasonably unable to use or conduct its operations in part or all of the Premises. If a Service Failure is a result of any cause other than Tenant’s acts or omissions, and results in a loss of service to the Premises and to more than fifty percent (50%) of the Building, Tenant shall have the right to terminate this Lease if Landlord fails or is unable to restore such services within six (6) months from the date of interruption and Tenant is reasonably unable to use or conduct its operations in a substantial part or all of the Premises. If a Service Failure is a result of any cause other than Tenant’s acts or omissions, and results in a loss of service to the Premises but to less than fifty percent (50%) of the Building, Tenant shall have the right to terminate this Lease if Landlord fails or is unable to restore such services within three (3) months from the date of interruption and Tenant is reasonably unable to use or conduct its operations in a substantial part or all of the Premises.

Tenant shall have the right to contest the validity or amount of any such taxes by appropriate proceedings diligently conducted in good faith.

Section 6.8 Assignment and Subleases.

The Tenant shall not assign, mortgage, pledge, hypothecate or otherwise transfer this Lease, or sublet (which term, without limitation, shall include granting of concessions, licenses and the like) the whole or any part of the Premises without, in each instance, having first received the consent of the Landlord which consent shall not be unreasonably withheld or delayed. Except as specifically permitted herein, any assignment or sublease made without such consent shall be void. If Tenant (or any subtenant) is a corporation, the provisions of this Section 6.8 shall apply to a direct or indirect transfer (however accomplished, whether in a single transaction or in a series of related or unrelated transactions) of stock (or any other mechanism such as, by way of example, the issuance of additional stock, a stock voting agreement or change in class(es) of stock) which results in a change of control of Tenant (or such subtenant) as if such

ACTIVE/103568117.9

transfer of stock (or other mechanism) which results in a change of control of Tenant (or such subtenant) were an assignment of this Lease except that the transfer of the outstanding capital stock of Tenant or any subtenant by persons or parties through the “over the counter market” or through any recognized stock exchange, (other than those deemed “insiders” within the meaning of the Securities Exchange Act of 1934, as amended) shall not be deemed an assignment of this Lease. If Tenant (or such subtenant) is a partnership, joint venture or limited liability company (herein called a “LLC”), the provisions of this Section 6.8 shall apply with respect to a direct or indirect transfer (however accomplished, whether in a single transaction or in a series of related or unrelated transactions) of an interest in the distributions of profits and losses of such partnership, joint venture or LLC (or other mechanism, such as, by way of example, the creation of additional general partnership or limited partnership interests) which results in a change of control of such partnership, joint venture or LLC, as if such transfer of an interest in the distributions of profits and losses of such partnership, joint venture or LLC which results in a change of control of such partnership, joint venture or LLC were an assignment of this Lease.

Notwithstanding anything to the contrary contained in this Section, upon not less than thirty (30) days’ prior notice to Landlord, Tenant shall have the right to assign this Lease or sublease all or any portion of the Premises, without obtaining the prior consent of Landlord, (a) to the purchaser of all or substantially all of Tenant’s assets, or to any entity into which the Tenant may be merged or consolidated (along with all or substantially all of its assets), (b) to a successor to Tenant if such succession takes place by a merger, consolidation, reorganization, stock sale, asset purchase, act of legislature or otherwise, and (c) any Affiliate (as defined below) so long as such Affiliate remains in such relationship to Tenant (the transferee in each subsections (a) through (c) hereinafter referred to as the “Acquiring Company”); provided that (i) the Acquiring Company continues to operate the business conducted in the Premises for the Permitted Uses described in Exhibit A hereto, (ii) the Acquiring Company shall assume in writing, in form acceptable to Landlord, all of Tenant’s obligations under this Lease, (iii) the Acquiring Company is a reputable entity of good character and has a net worth computed in accordance with generally accepted accounting principles at least equal to the net worth of Tenant immediately prior to such merger, consolidation or transfer and proof satisfactory to Landlord of such net worth shall have been delivered to Landlord at least ten (10) days prior to the effective date of any such transaction, (iv) Tenant shall provide to Landlord such additional information regarding the Acquiring Company as Landlord shall reasonably request; and (v) Tenant shall pay Landlord’s reasonable expenses actually incurred in connection therewith. An “Affiliate” shall mean any entity which is directly or indirectly through one or more intermediaries controls, is under common control with or is controlled by Tenant. For purposes of the preceding sentence, the term “control” (including the terms “controlled by” and “under common control with”) means the possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of such Person, whether through ownership of voting securities, by contract or otherwise. Unless Landlord shall have objected to an assignment or transfer by Tenant within ten (10) business days following Landlord’s receipt of the information or items described in subsections (ii) and (iii) above, Landlord shall be deemed to have waived its right to object thereto. The transfers described in this paragraph are referred to hereinafter as “Permitted Transfers.”

ACTIVE/103568117.9

Whether or not the Landlord consents, or is required to consent, to any assignment or subletting, the Tenant named herein shall remain fully and primarily liable for the obligations of the tenant hereunder, including, without limitation, the obligation to pay Annual Fixed Rent and Additional Rent provided under this Lease. The Tenant shall give the Landlord notice of any proposed sublease or assignment, whether or not the Landlord’s consent is required hereunder, specifying the provisions of the proposed subletting or assignment, including (x) the name and address of the proposed subtenant or assignee, (y) a copy of the proposed subtenant’s or assignee’s most recent annual financial statement, and (z) all of the terms and provisions upon which the proposed subletting or assignment is to be made and such other information concerning the proposed subletting or assignment is to be made and such other information concerning the proposed subtenant or assignee as the Tenant has obtained in connection with the proposed subletting or assignment. Only in the event that Landlord, in its sole and absolute discretion, has agreed in writing to release Tenant from all liability under this Lease upon the assignment of this Lease or sublease of all or any portion of the Premises or as otherwise is required in connection with a Permitted Transfer, may Landlord require evidence to the reasonable satisfaction of Landlord that the net assets of the proposed assignee or subtenant are not less than the assets of Tenant at the time of the signing of the Lease.

The Tenant shall reimburse the Landlord promptly after receiving a written invoice thereof for reasonable legal and other expenses actually incurred by the Landlord in connection with any request by the Tenant for consent to any assignment or subletting. If this Lease is assigned, and Tenant is in default beyond any grace or cure period under the Lease, the Landlord may, upon prior written notice to Tenant, at any time and from time to time, collect rent and other charges from the assignee, sublessee or occupant and apply the net amount collected to the rent and other charges herein reserved, but no such assignment, subletting, occupancy or collection shall be deemed a waiver of the prohibitions contained in this Section 6.8 or the acceptance of the assignee, sublessee or occupant as a tenant, or a release of the Tenant from the further performance by the Tenant of covenants on the part of the Tenant herein contained.

The Tenant shall pay to the Landlord fifty percent (50%) of any amounts the Tenant actually receives from any subtenant or assignee as rent, additional rent or other forms of compensation or reimbursement for the sublease, assignment or occupancy of the Premises, after deducting therefrom (1) the then due and payable proportionate monthly share of Annual Fixed Rent, Additional Rent and all other monies due to Landlord pursuant to this Lease (allocable in the case of a sublease to that portion of the Premises being subleased), and (2) all reasonable and customary sublease expenses (including but not limited to bona fide brokerage fees, fit up expenses, free rent periods, marketing costs and attorney’s fees) incurred by Tenant. The preceding sentence shall not apply to any Permitted Transfers. The consent by the Landlord to an assignment or subletting shall not be construed to relieve the Tenant from obtaining the express consent in writing of the Landlord to any further assignment or subletting.

Notwithstanding anything to the contrary contained herein, Tenant shall be permitted to allow the occupancy of the Premises or portions thereof by companies, firms or other entities who are members of a group with whom Tenant has a contractual or other relationship providing for cooperative or collaborative research or development work, who are or typically would be

ACTIVE/103568117.9

located by Tenant in one of its facilities (each, a “Collaborative User”), without the prior written consent of Landlord, provided, however, that Tenant shall provide Landlord with written notice of such situations if such occupancy involves more than ten (10) people for a period of greater than six (6) months. Tenant shall be fully responsible for ensuring that any such parties comply with the terms of the Lease and Tenant shall at all times remain primarily liable under the Lease.

Landlord agrees to defend, indemnify and save harmless Tenant from legal action, damages, loss, liability and any other expense in connection with loss of life, bodily or personal injury or property damage, arising from or out of the intentional or willful misconduct or gross negligence of Landlord, its agents, employees, licensees, servants, invitees or contractors, which occur in or about the Premises, outside the Premises but within the Building, on the Land, on the access roads and ways, in the parking facilities provided pursuant to the Lease, within University Park or any adjacent area maintained by Landlord, except to the extent that such loss of life, bodily or personal injury or property damage is due to the willful misconduct or act, omission or neglect of Tenant, its agents, contractors, employees, licensees, invitees or servants.

Section 7.2 Liability Insurance.

The Tenant agrees to maintain in full force from the date upon which the Tenant first enters the Premises for any reason, throughout the Term, and thereafter, so long as the Tenant is in occupancy of any part of the Premises, a policy of commercial general liability insurance under which the Landlord, the Building’s managing agent, any ground lessor and any holder of a first mortgage on the Property of whom the Tenant is notified in writing by the Landlord (collectively, the “Additional Named Insureds”) are named as additional insureds, and under which the insurer provides a contractual liability endorsement insuring against all cost, expense and liability arising out of or based upon any and all claims, accidents, injuries and damages described in Section 7.1, in the broadest form of such coverage from time to time available. Each such policy shall be noncancelable and nonamendable (to the extent that any proposed amendment reduces the limits or the scope of the insurance required in this Lease) with respect to the Landlord and such ground lessor and first mortgagee without· thirty (30) days’ prior notice to the Landlord and the Additional Named Insureds and a certificate of insurance shall be delivered to the Landlord.

The minimum limits of liability of such insurance as of the Commencement Date shall be Three Million Dollars ($3,000,000.00) per occurrence and Five Million Dollars ($5,000.000.00) in the aggregate for combined bodily injury (or death) and damage to property, and from time to time during the Term such limits of liability shall be increased to reflect such higher limits as are customarily required pursuant to new leases of space in the Boston/Cambridge area with respect to similar properties and similar uses.

Section 7.3 Alterations, Improvements and Betterments; Personal Property at Risk.

The Tenant agrees to maintain in full force at all times throughout the Term, policy(s) of all risk property damage insurance, naming Landlord (and the Additional Named Insureds) and the Tenant as insureds as their interests may appear, covering all present and future Tenant Removable Property, Landlord Retained Property, and all present and future alterations, leasehold improvements and betterments in the Premises to the extent of their full replacement costs as updated from time to time during the Term, such insurance to include a replacement cost endorsement.

The Tenant agrees that all of the furnishings, fixtures, equipment, effects and property of every kind, nature and description of the Tenant and of all persons claiming by, through or- under the Tenant which, during the continuance of this Lease or any occupancy of the Premises by the Tenant or anyone claiming under the Tenant which, during the continuance of this Lease or any occupancy of the Premises by the Tenant or anyone claiming under the Tenant may be on the Premises or elsewhere in the Building or on the Land or parking facilities provided hereby, shall be at the sole risk and hazard of the Tenant, and if the whole or any part thereof shall be destroyed or damaged by fire, water or otherwise, or by the leakage or bursting of water pipes, steam pipes, or other pipes, by theft or from any other cause, no part of said loss or damage is to be charged to or be borne by the Landlord, except that the Landlord shall in no event be exonerated from any liability to the Tenant (subject to Section 7.5 hereof) for any injury, loss,

ACTIVE/103568117.9

damage or liability to the extent same is caused by Landlord’s, or its agents’, employees’, servants’ or contractors’ negligence or willful misconduct.

Section 7.4 Landlord’s Insurance.

The Landlord shall carry, or cause to be carried, such casualty and liability insurance upon and with respect to operations at the Building as may from time to time be deemed reasonably prudent by the Landlord or required by any mortgagee holding a mortgage thereon or any ground lessor of the Land, and in any event, insurance against loss by fire and the risks now covered by extended coverage endorsement No. 4 in an amount at least equal to the full replacement cost of the Building, exclusive of foundations, excavations and footings.

Section 7.5 Waiver of Subrogation.

Any property insurance carried by either party, or required to be carried by either party, with respect to the Building, Land, Premises, parking facilities or any property therein or occurrences thereon shall, without further request by either party, include a clause or endorsement denying to the insurer rights of subrogation against the other party to the extent rights have been waived by the insured prior to occurrence of any claim, damage, injury or loss. Each party, notwithstanding any provisions of this Lease to the contrary, hereby waives any claims or rights of recovery against the other for injury or loss, including, without limitation, injury or loss caused by negligence of such other party to the extent covered by property insurance actually carried or required to be carried hereunder.

ARTICLE VIII

CASUALTY AND EMINENT DOMAIN

Section 8.1 Restoration Following Casualties.

If, during the Term, the Building or the Premises shall be damaged by fire or casualty, subject to the exceptions and limitations provided below, the Landlord shall proceed promptly to exercise diligent efforts to restore, or cause to be restored, the Building and the core and shell of the Premises (excluding alterations, improvements and betterments and the property which Tenant is obligated to insure under the Lease), as the case may be, to substantially the condition thereof just prior to time of such damage, but the Landlord shall not be responsible for delay in such restoration which may result from External Causes or due to any act, failure to act or neglect of Tenant or Tenant’s servants, agents, employees or licensees. The Landlord shall have no obligation to expend in the reconstruction of the Building more than the actual amount of insurance proceeds made available to the Landlord by its insurer and not retained by the Landlord’s mortgagee or ground lessor. Tenant shall, promptly following Landlord’s restoration of the core and shell of the Premises, restore the alterations, improvements, betterments and property in the Premises.

Any restoration of the Building or the Premises shall be altered to the extent necessary to comply with then current laws and applicable codes.

ACTIVE/103568117.9

Section 8.2 Landlord’s Termination Election.

If the Landlord reasonably determines that the amount of insurance proceeds available to the Landlord is insufficient to cover the cost of restoring the Building or if in the reasonable opinion of the Landlord the Building has been so damaged that it is appropriate for the Landlord to raze or substantially reconstruct the Building, then the Landlord may terminate this Lease by giving notice to the Tenant within ninety (90) days after the date of the casualty or such later date as is required to allow the Landlord a reasonable time to make either such determination, but in no event later than one hundred twenty (120) days from the date of the casualty. Any such termination shall be effective on the date designated in such notice from the Landlord, but in any event, not later than ninety (90) days after such notice, and if no date is specified, effective upon the delivery of such notice.

Section 8.3 Tenant’s Termination Election.

After any casualty which materially impairs the use of a material portion of the Premises, unless the Landlord has earlier advised the Tenant of the Landlord’s election to terminate this Lease pursuant to Section 8.2, or to restore the Premises and maintain this Lease in effect pursuant to Section 8.1, the Tenant shall have the right, after the expiration of the ninety (90) day period provided in Section 8.2 above, to give a written notice to the Landlord requiring the Landlord within ten (10) days thereafter to exercise or waive any right of the Landlord to terminate this Lease pursuant to Section 8.2 as a result of such casualty and if the Landlord fails to give timely notice to the Tenant waiving any right under Section 8.2 to terminate this Lease based on such casualty, the Tenant shall be entitled, at any time until the Landlord has given notice to the Tenant waiving such termination right, to give notice to the Landlord terminating this Lease.

Where the Landlord is obligated to restore the Premises, unless such restoration is completed within two (2) months following the date estimated by Landlord for restoration completion in a written notice to Tenant delivered within ninety (90) days following the date of the casualty, such period to be subject, however, to extension where the delay in completion of such work is due to External Causes (not to exceed an additional two (2) months on account of such External Causes) or due to any act, failure to act or neglect of Tenant or Tenant’s servants, agents, employees or licensees, the Tenant shall have the right to terminate this Lease at any time after the expiration of such period until the restoration is substantially completed, such termination to take effect as of the date of the Tenant’s notice.

Tenant shall be solely responsible for (A) the amount of any deductible under the policy insuring Tenant’s improvements and betterments and (B) the amount, if any, by which the cost of repairing and restoring Tenant’s improvements and betterments exceeds the available insurance proceeds therefor.

Except as expressly provided in this Article VIII, Tenant shall not be entitled to terminate this Lease and Landlord shall have no liability to Tenant for inconvenience, loss of business or annoyance arising from any repair or restoration of any portion of the Premises or of the Building pursuant to this Article VIII.

ACTIVE/103568117.9

Section 8.4 Casualty at Expiration of Lease.

If the Premises shall be damaged by fire or casualty in such a manner that the Premises cannot, in the ordinary course, reasonably be expected to be repaired within one hundred twenty (120) days from the commencement of repair work and such damage occurs within the last two (2) years of the Term (as the same may have been extended prior to such fire or casualty), either party shall have the right, by giving notice to the other not later than sixty (60) days after such damage, to terminate this Lease, whereupon this Lease shall terminate as of the date of such notice.

Section 8.5 Eminent Domain.

Except as hereinafter provided, if the Premises, or such portion thereof as to render the balance (if reconstructed to the maximum extent practicable in the circumstances) unsuitable for the Tenant’s purposes, shall be taken by condemnation or right of eminent domain, the Landlord or the Tenant shall have the right to terminate this Lease by notice to the other of its desire to do so, provided that such notice is given not later than thirty (30) days after the effective date of such taking. If so much of the Building shall be so taken that the Landlord reasonably determines that it would be appropriate to raze or substantially alter the Building, the Landlord shall have the right to terminate this Lease by giving notice to the Tenant of the Landlord’s desire to do so not later than thirty (30) days after the effective date of such taking.

Should any part of the Premises be so taken or condemned during the Term, and should this Lease be not terminated in accordance with the foregoing provisions, the Landlord agrees to use reasonable efforts to put what may remain of the Premises into proper condition for use and occupation as nearly like the condition of the Premises prior to such taking as shall be practicable, subject, however, to applicable laws and codes then in existence and to the availability of sufficient proceeds from the eminent domain taking not retained by any mortgagee or ground lessor.

Section 8.6 Rent After Casualty or Taking.

If the Premises shall be damaged by fire or other casualty, the Annual Fixed Rent and Additional Rent shall be justly and equitably abated and reduced according to the nature and extent of the loss of use thereof suffered by the Tenant from the date of the casualty through the date that Landlord substantially completes Landlord’s restoration work to the Premises. In the event of a taking which reduces the area of the Premises, a just proportion of the Annual Fixed Rent shall be abated for the period of such taking.

Section 8.7 Taking Award.

The Landlord shall have and hereby reserves and accepts, and the Tenant hereby grants and assigns to the Landlord, all rights to recover for damages to the Building and the Land, and the leasehold interest hereby created, and to compensation accrued or hereafter to accrue by reason of such taking, damage or destruction, as aforesaid, and by way of confirming the foregoing, the Tenant hereby grants and assigns to the Landlord, all rights to such damages or

ACTIVE/103568117.9

compensation. Nothing contained herein shall be construed to prevent the Tenant from prosecuting in any condemnation proceedings a claim for relocation expenses and Tenant’s trade fixtures and equipment in the Premises, provided that such action shall not affect the amount of compensation otherwise recoverable by the Landlord from the taking authority pursuant to the preceding sentence.

ARTICLE IX

DEFAULT

Section 9.1 Tenant’s Default.

Each of the following shall constitute an “Event of Default”:

(9)Failure on the part of the Tenant to pay the Annual Fixed Rent, Additional Rent or other charges for which provision is made herein on or before the date on which the same become due and payable, if such condition continues for ten (10) days after written notice from the Landlord that the same are past due; provided, however, an Event of Default shall occur hereunder without any obligation of Landlord to give any notice, if Landlord has given Tenant written notice under this Section 9.1(a) on more than two (2) occasions during the twelve (12) month interval preceding such failure to pay by Tenant.

(10)Failure on the part of the Tenant to perform or observe any other term or condition contained in this Lease if the Tenant shall not cure such failure within thirty (30) days after notice from the Landlord to the Tenant thereof, provided that in the case of breaches of obligations under this Lease which cannot be cured within thirty (30) days through the exercise of due diligence, so long as the Tenant commences such cure within thirty (30) days, and the Tenant diligently pursues such cure, such breach shall not be deemed to create an Event of Default.

(11)The taking of the estate hereby created on execution or by other process of law; or a judicial declaration that the Tenant is bankrupt or insolvent according to law; or any assignment of the property of the Tenant for the benefit of creditors, or the appointment of a receiver, guardian, conservator, trustee in bankruptcy or other similar officer to take charge of all or any substantial part of the Tenant’s property by a court of competent jurisdiction; or the filing .of an involuntary petition against the Tenant under any provisions of the bankruptcy act now or hereafter enacted if the same is not dismissed within ninety (90) days; the filing by the Tenant of any voluntary petition for relief under provisions of any bankruptcy law now or hereafter enacted.

If an Event of Default shall occur, then, in any such case, whether or not the Term shall have begun, the Landlord lawfully may, immediately or at any time thereafter, give notice to the Tenant specifying the Event of Default and this Lease shall come to an end on the date specified therein as fully and completely as if such date were the date herein originally fixed for the expiration of the Lease Term, and the Tenant will then quit and surrender the Premises to the Landlord, but the Tenant shall remain liable as hereinafter provided.

ACTIVE/103568117.9

Section 9.2 Damages.

In the event that this Lease is terminated pursuant to Section 9.1 above, Tenant covenants to pay punctually to Landlord all the sums (“Periodic Payments”) and perform all the obligations which Tenant covenants in this Lease to pay and to perform in the same manner and to the same extent and at the same time as if this Lease had not been terminated. In calculating the amounts to be paid by Tenant under the foregoing covenant, Tenant shall be credited with the net proceeds of any rent obtained by reletting the Premises, after deducting all of Landlord’s reasonable expenses in connection with such reletting, including, without limitation, all repossession costs, brokerage commissions, fees for legal services and expenses for preparing the Premises for reletting. The Landlord may (i) relet the Premises, or any part or parts thereof, for a term or terms which may, at the Landlord’s option, exceed or be equal to or less than the period which would otherwise have constituted the balance of the Term, and may grant such concessions and free rent as the Landlord in its reasonable commercial judgment considers advisable or necessary to relet the same, and (ii) make such alterations, repairs and improvements in the Premises as the Landlord in its reasonable commercial judgment considers advisable or necessary to relet the same. Landlord agrees to use diligent, good faith efforts to relet the Premises, but the Landlord may, at its option, seek to rent other properties of the Landlord prior to reletting the Premises. Subject to the obligations of Landlord in the preceding sentence, no action of the Landlord or failure to relet in accordance with the foregoing shall operate to release or reduce the Tenant’s liability hereunder.

At any time following the termination of this Lease, Landlord may elect to receive, in lieu of receiving further Periodic Payments, an amount (the “Lump Sum Payment”) equal to the excess, if any, of the discounted present value of the total rent reserved for the remainder of the Term after such election over the then discounted present fair rental value of the Premises for the remainder of the Term after such election. In calculating the rent reserved, there shall be included, in addition to the Annual Fixed Rent and all Additional Rent (assuming that Real Estate Taxes and Operating Expenses for the Property will increase annually by a reasonable amount), the value of all other considerations agreed to be paid or performed by Tenant over the remainder of the Term.

Section 9.3 Cumulative Rights.

The specific remedies to which the Landlord may resort under the terms of this Lease are cumulative and are not intended to be exclusive of any other remedies or means of redress to which it may be lawfully entitled in case of any breach or threatened breach by the Tenant of any provisions of this Lease. In addition to the other remedies provided in this Lease, the Landlord shall be entitled to the restraint by injunction of the violation or attempted or threatened violation of any of the covenants, conditions or provisions of this Lease or to a decree compelling specific performance of any such covenants, conditions or provisions. Nothing contained in this Lease shall limit or prejudice the right of the Landlord to prove for and obtain in proceedings for bankruptcy, insolvency or like proceedings by reason of the termination of this Lease, an amount equal to the maximum allowed by any statute or rule of law in effect at the time when, and

ACTIVE/103568117.9

governing the proceedings in which, the damages are to be proved, whether or not the amount be greater, equal to, or less than the amount of the loss or damages referred to above.

Section 9.4 Landlord’s Self-help.

If the Tenant shall at any time default in the performance of any obligation under this Lease, the Landlord shall have the right, but not the obligation, after expiration of any applicable notice and grace period, upon reasonable, but in no event more than ten (10) days’ notice to the Tenant (except in case of emergency in which case no notice need be given), to perform such obligation. The Landlord may exercise its rights under this Section without waiving any other of its rights or releasing the Tenant from any of its obligations under this Lease.

Section 9.5 Enforcement Expenses.

If either party hereto fails to perform any of its obligations under this Lease or if any dispute arises between the parties hereto concerning the meaning or interpretation of any provision of this Lease, then the defaulting party or the party not prevailing in such dispute, as the case may be, shall pay any and all costs and expenses reasonably incurred by the other party on account of such default and/or in enforcing or establishing its rights hereunder, including, but not limited to, court costs, expert fees and costs and attorneys’ fees and disbursements. A party shall be deemed to have prevailed in any such action if such action is dismissed upon the payment by the other party of the sums allegedly due or the performance of obligations allegedly not complied with, or if such party obtains substantially the relief sought by it in the action, irrespective of whether such action is prosecuted to judgment. If either party hereto be made or becomes a party to any litigation commenced by or against the other party by or against a third party, or incurs costs or expenses related to such litigation, involving any part of the Property and the enforcement of any of the rights, Obligations or remedies of such party, then the party becoming involved in any such litigation because of a claim against such other party hereto shall receive from such other party hereto all costs and reasonable attorneys’ fees incurred by such party in such litigation.

Section 9.6 Late Charges and Interest on Overdue Payments.

In the event that any payment of Annual Fixed Rent or Additional Rent shall remain unpaid for a period of ten (10) days after the same are due, there shall become due to the Landlord from the Tenant, as Additional Rent and as compensation for the Landlord’s extra administrative costs in investigating the circumstances of late rent, a late charge of two percent (2%) of the amount overdue. In addition, any Annual Fixed Rent and Additional Rent not paid when due shall bear interest from the date due to the Landlord until paid at the variable rate (the “Default Interest Rate”) equal to the higher of (i) the rate at which interest accrues on amounts not paid when due under the terms of the Landlord’s financing for the Building, as from time to time in effect, and (ii) one hundred and twentyfive percent (125%) of the Prime Rate (as defined in Section 3.3(b) hereof).

Section 9.7 Landlord’s Right to Notice and Cure.

ACTIVE/103568117.9

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

Any action for the foreclosure of an existing mortgage on the Property shall not terminate this Lease or cause this Lease to be terminable by Tenant by reason of the termination of any such ground lease unless Tenant is specifically named and joined in any such action and unless a judgment is obtained therein against Tenant resulting in a termination of this Lease.

Section 10.2 Prepayment of Rent not to Bind Mortgagee.

No Annual Fixed Rent, Additional Rent, or any other charge payable to the Landlord shall be paid more than thirty (30) days prior to the due date thereof under the terms of this Lease and payments made in violation of this provision shall (except to the extent that such payments are actually received by a mortgagee or ground lessor) be a nullity as against such mortgagee or ground lessor and the Tenant shall be liable for the amount of such payments to such mortgagee or ground lessor.

Section 10.3 Tenant’s Duty to Notify Mortgagee; Mortgagee’s Ability to Cure.

No act or failure to act on the part of the Landlord which would entitle the Tenant under the terms of this Lease, or by law, to be relieved of the Tenant’s obligations to pay Annual Fixed Rent or Additional Rent hereunder or to terminate this Lease, shall result in a release or termination of such obligations of the Tenant or a termination of this Lease unless (i) the Tenant

ACTIVE/103568117.9

Section 11.3 Successors and Limitation on Liability on the Landlord.

The obligations of this Lease shall run with the land, and this Lease shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, except that the original Landlord named herein and each successor Landlord shall be liable only for obligations accruing during the period of its ownership. The obligations of the Landlord shall be binding upon the assets of the Landlord consisting of an equity ownership of the Property (and including any proceeds realized from the sale of such Property) but not upon other assets of the Landlord and neither the Tenant, nor anyone claiming by, under or through the Tenant, shall be entitled to obtain any judgment creating personal liability on the part of the Landlord or enforcing any obligations of the Landlord against any assets of the Landlord other than an equity interest in the Property.

Section 11.4 Waivers by the Landlord or Tenant.

The failure of the Landlord or the Tenant to seek redress for violation of, or to insist upon strict performance of, any covenant or condition of this Lease, shall not be deemed a waiver of such violation nor prevent a subsequent act, which would have originally constituted a violation from having all the force and effect of an original violation. The receipt by the Landlord of Annual Fixed Rent or Additional Rent with knowledge of the breach of any covenant of this Lease shall not be deemed a waiver of such breach.

No provision of this Lease shall be deemed to have been waived by the Landlord or the Tenant, unless such waiver be in writing signed by the waiving party. No consent or waiver, express or implied, by the Landlord or the Tenant to or of any breach of any agreement or duty shall be construed as a waiver or consent to or of any other breach of the same or any other agreement or duty.

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

ACTIVE/103568117.9

If any term of this Lease, or the application thereof to any person or- circumstances, shall to any extent be invalid or unenforceable, the remainder of this Lease, or the application of such term to persons or circumstances other than those as to which it is invalid or unenforceable, shall not be affected thereby, and each term of this Lease shall be valid and enforceable to the fullest extent permitted by law. The titles of the Articles are for convenience only and not to be considered in construing this Lease. This Lease contains all of the agreements of the parties with respect to the subject matter thereof and supersedes all prior dealings between them with respect to such subject matter.

Section 11.7 Quiet Enjoyment.

Each party represents and warrants to the other that it has had no dealings with any broker or agent in connection with this Lease other than ▇▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇▇, CBRE and JLL New England, LLC and shall indemnify and hold harmless the other from claims for any brokerage commission by any other broker or agent claiming same by, through or under the indemnifying party. The terms of this Section 11.8 shall survive the expiration or earlier termination of this Lease.

Section 11.9 Surrender of Premises and Holding Over.

The Tenant shall surrender possession of the Premises on the last day of the Term and the Tenant waives the right to any notice of termination or notice to quit. The Tenant covenants that upon the expiration or sooner termination of this Lease, it shall, without notice, deliver up and surrender possession of the Premises in the same condition in which the Tenant has agreed to keep the same during the continuance of this Lease and in accordance with the terms hereof, including the decommissioning requirements of this Section 11.9, reasonable wear and tear and damage by fire or other casualty or eminent domain taking and damage by the negligence or willful misconduct of Landlord or its agents, contractors or employees excepted, first removing therefrom all goods and effects of the Tenant and the Tenant Removable Property and any leasehold improvements Landlord specified for removal pursuant to Section 4.2, and repairing all damage caused by such removal. Upon the expiration of this Lease or if the Premises should be abandoned by the Tenant, or this Lease should terminate for any cause, and at the time of such expiration, vacation, abandonment or termination, the Tenant or Tenant’s agents, subtenants or any other person should leave any property of any kind or character on or in the Premises, the fact of such leaving of property on or in the Premises shall be conclusive evidence of intent by the Tenant, and individuals and entities deriving their rights through the Tenant, to abandon such property so left in or upon the Premises, and such leaving shall constitute abandonment of the property. Landlord shall have the right and authority without notice to the Tenant or anyone else, to remove and destroy, or to sell or authorize disposal of such property, or any part thereof,

ACTIVE/103568117.9

without being in any way liable to the Tenant therefor and the proceeds thereof shall belong to the Landlord as compensation for the removal and disposition of such property. Notwithstanding anything to the contrary contained in this Lease, Tenant shall not be obligated to restore the Premises or remove any alterations or additions to the Premises at the end of the Term, except for any new items installed after the Commencement Date of this Lease which Landlord identified in written notice delivered prior to Landlord approving Tenant’s plans for any alterations or improvements as items which Tenant must remove prior to the expiration of the Lease. Tenant shall not be required to remove its computer and telecommunications wiring, cable and other equipment; provided, however, that to the extent that Tenant replaces any such wiring and cable during the Term or any other extension thereof then it shall, as part of that installation pull and remove from the Premises any wiring and cable that it no longer uses from the specific portion of the Premises in which Tenant is replacing such wiring or cabling. Tenant will yield-up the Premises to Landlord in broom swept condition, reasonable wear and tear and damage resulting from casualty excepted.

At least three (3) months prior to the surrender of the Premises, Tenant shall deliver to Landlord a narrative description of the actions proposed (or required by any governmental authority) to be taken by Tenant in order to surrender the Premises (including any alterations permitted by Landlord to remain in the Premises, and the Landlord Retained Property) and any ductwork or other areas or systems of the Building requiring decommissioning at the expiration or earlier termination of the Term, free from any residual impact from Tenant’s use of Hazardous Materials and otherwise released for unrestricted use and occupancy (the “Surrender Plan”). Tenant’s Surrender Plan shall state that (a) all laboratory space in the Premises and other areas of the Building used by Tenant, including (i) all floors, walls, ceilings, counters, piping, supply lines, waste lines and plumbing in or exclusively serving the Premises, and (ii) all exhaust or other ductwork in or exclusively serving the Premises or in the Building used exclusively by or for the Premises will be de-commissioned to the extent required by, and in accordance with, applicable Legal Requirements and in accordance with best industry practice; (b) the interior surfaces of the Premises (including floors, walls, ceilings, and counters), piping, supply lines, waste lines and plumbing, and all such exhaust or other ductwork in the Premises, may be released for unrestricted use and occupancy or disposed of in compliance with applicable Legal Requirements without: (y) incurring special costs on account of uncompleted de-commissioning work; or (z) undertaking special procedures for demolition, disposal, investigation, assessment, cleaning or removal of such Hazardous Materials related to the former laboratory and clinical use areas of the Premises; and (c) the Premises may be occupied for office and laboratory use, or demolished or renovated. The final report shall also include reasonable detail concerning the clean-up measures that were taken, the clean-up locations, the tests run and the analytic results. If Tenant fails to perform its obligations under this 11.9 without limiting any other right or remedy, Landlord may, on five (5) business fays’ prior written notice to Tenant, perform such obligations at Tenant’s expense, and Tenant shall within ten (10) days of demand reimburse Landlord for all out-of-pocket costs and expenses incurred by Landlord in connection with such work. Tenant’s obligations under this Section 11.9 shall survive the expiration or earlier termination of this Lease.

ACTIVE/103568117.9

On or before such surrender, Tenant shall deliver to Landlord evidence that the approved Surrender Plan shall have been satisfactorily completed and Landlord shall have the right, subject to reimbursement at Tenant’s expense as set forth below, to cause Landlord’s environmental consultant to inspect the Premises and perform such additional procedures as may be deemed reasonably necessary to confirm that the Premises are, as of the effective date of such surrender or early termination of the Lease, free from any residual impact from Tenant laboratory operations. Tenant shall reimburse Landlord, within ten (10) days of demand as Additional Rent, for the expense incurred by Landlord for Landlord’s environmental consultant to review and approve the Surrender Plan and to visit the Premises and verify satisfactory completion of the same. Landlord shall have the unrestricted right to deliver such Surrender Plan and any report by Tenant’s or Landlord’s environmental consultants with respect to the surrender of the Premises to third parties; provided, however, that such Surrender Plan may be accompanied by a statement alerting any other recipient (other than Landlord Parties) that said other recipient shall not be entitled to rely on the Surrender Plan. Notwithstanding the foregoing, upon receipt of a written request from Landlord, Tenant will exercise reasonable efforts (at no additional cost to Tenant) to obtain a reliance letter from the issuer that such Surrender Plan may be relied upon by the subsequent tenant of the Premises (but not any tenants beyond that).

If the Tenant fails to surrender possession of the Premises upon the expiration or sooner termination of this Lease, the Tenant shall pay to Landlord, as rent for any period after the expiration or sooner termination of this Lease an amount equal to one hundred fifty percent (150%) of the Annual Fixed Rent and the Additional Rent required to be paid under this Lease as applied to any period in which the Tenant shall remain in possession. Acceptance by the Landlord of such payments shall not constitute a consent to a holdover hereunder or result in a renewal or extension of the Tenant’s rights of occupancy. Such payments shall be in addition to and shall not affect or limit the Landlord’s right of reentry, Landlord’s right to collect such damages as may be available at law, or any other rights of the Landlord under this Lease or as provided by law.

Section 11.10 Ground Lease.

This Lease is in all respects subject to the ground lease (the “Ground Lease”) between the Landlord’s predecessor in interest as lessee and the Massachusetts Institute of Technology (“MIT”) as lessor dated April 20, 1986, as amended by that certain First Amendment to Construction and Lease Agreement dated as of December 15, 1997, and that certain Second Amendment to Construction and Lease Agreement dated as of June 12, 2000. If the Ground Lease shall terminate during the Term for any reason whatsoever, except as may otherwise be agreed in a non-disturbance agreement between Tenant and MIT, this Lease shall be terminable by Landlord in its sole discretion with the same force and effect as if such termination date had been named herein as the date of expiration hereof.

The Tenant agrees to sign an agreement with the Employment and Training Agency designated by the City Manager of the City of Cambridge as provided in subsections (a) - (g) of Section 244 of Ordinance Number 1005 of the City of Cambridge, adopted April 23, 1984.

Section 11.14 Parking and Transportation Demand Management.

Tenant covenants and agrees to work cooperatively with Landlord to develop a parking and transportation demand management (“PTDM”) program that comprises part of a comprehensive PTDM for University Park. In connection therewith, the use of single occupant vehicle commuting will be discouraged and the use of alternative modes of transportation and/or alternative work hours will be promoted. Without limitation of the foregoing, Tenant agrees that its PTDM program {and Tenant will require in any sublease or occupancy agreement permitting occupancy in the Premises that such occupant’s PTDM program) will include offering a subsidized MBTA transit pass, either constituting a full subsidy or a subsidy in an amount equal to the maximum deductible amount therefore allowed under the federal tax code, to any employee working in the Premises requesting one. Tenant agrees to comply with the traffic mitigation measures required by the City of Cambridge, and Tenant shall otherwise comply with all legal requirements of the City of Cambridge pertaining thereto.

Section 11.15 REIT Savings.

If Landlord or any affiliate of Landlord has elected to qualify as a real estate investment trust (a “REIT”), any service required or permitted to be performed by Landlord pursuant to the Lease or this Agreement, the charge or cost of which may be treated as impermissible tenant service income under the laws governing a REIT, may be performed by a taxable REIT subsidiary that is affiliated with either Landlord or Landlord’s property manager, an independent contractor of Landlord or Landlord’s property manager (the “Service Provider”). If Tenant is subject to a charge under the Lease or this Agreement for any such service, then, at Landlord’s direction, Tenant will pay such charge either to Landlord for further payment to the Service Provider or directly to the Service Provider, and, in either case, (i) Tenant’s actual costs for such service shall not increase, (ii) Landlord will credit such payment against any charge for such service made by Landlord to Tenant under the Lease, and (iii) such payment to the Service Provider will not relieve Landlord from any obligation under the Lease concerning the provisions of such service.
