Upon Landlord’s receipt of the Rent Certificate, Tenant’s obligation to pay the Base Rent for the applicable month shall xxxxx.

If the Rent Certificate indicates that Tenant’s out of pocket rent obligation under the One Xxxxxxx Square Lease is reduced or eliminated by virtue of entering into an assignment or sublease, termination agreement or suffering a recapture of such premises or other such means (each, an “OKS Rent Savings Event”), Landlord and Tenant shall split Tenant’s rent savings under the One Xxxxxxx Square Lease on a 60% to Landlord and 40% to Tenant basis after the deduction of reasonable documented transaction costs, including, but not limited to legal and brokerage fees, architectural and engineering fees, rental concessions and tenant improvement allowances, and any profits that Tenant is obligated to split with the landlord under the One Xxxxxxx Square Lease. If an OKS Rent Savings Event occurs, the amount of the Initial Rent Abatement that may be applied to Base Rent hereunder shall be reduced by the portion of the rent savings allocated to Landlord under the prior sentence. If an OKS Rent Savings Event occurs and the amount of the rent savings under the One Xxxxxxx Square Lease is greater than the remaining amount of the Initial Rent Abatement at such time, then Tenant shall pay Landlord, as additional rent, the rent savings allocated to Landlord amortized over the remainder of the stated term of the One Xxxxxxx Square Lease. The following examples illustrate three (but not all) possible scenarios that may arise in any given month under these Section:

(a) No OKS Rent Savings Event Occurs:

Tenant submits a Rent Certificate to Landlord evidencing that no OKS Rent Savings Event has occurred.

Tenant pays the monthly base rent of approximately $85,000 to landlord under the One Xxxxxxx Square Lease.

No Base Rent is paid to Landlord and the amount of the unapplied Initial Rent Abatement is reduced by the $287,424.67 rent payment otherwise due Landlord pursuant to Section 1.1 hereof.

(b) OKS Rent Savings Event Occurs Before the Expiration of the Base Rent Abatement Period:

Tenant submits a Rent Certificate to Landlord evidencing that Tenant and the landlord under the One Xxxxxxx Square Lease have entered into a lease termination agreement (i.e. an OKS Rent Savings Event) yielding a rent savings of $500,000 (after deduction of Tenant’s reasonable documented transaction costs).

Landlord’s share of the rent savings is $300,000 and Tenant’s share of the rent savings is $200,000.

Tenant pays the net monthly rent (or no monthly rent, as the case may be) due to landlord under the One Xxxxxxx Square Lease after accounting for the rent savings under the One Xxxxxxx Square Lease.

No Base Rent is paid to Landlord and the amount of the unapplied Initial Rent Abatement is reduced by $300,000 (the amount of Landlord’s share of the rent savings).

The Rent Commencement Date is accelerated accordingly based on the amount of Landlord’s share of the rent savings.

If the OKS Rent Savings Event occurs due to Tenant entering into a sublease for the premises under the One Xxxxxxx Square Lease, the rent savings and the corresponding reduction in the Initial Rent Abatement would be accounted for on a monthly basis as the actual rent savings is realized by Tenant under the One Xxxxxxx Square Lease.

(c) OKS Rent Savings Event Occurs After the Expiration of the Base Rent Abatement Period:

Tenant submits a Rent Certificate to Landlord evidencing the occurrence of an OKS Rent Savings Event and rent savings of $500,000 (after deduction of Tenant’s reasonable documented transaction costs).

Landlord’s share of the rent savings is $300,000 and Tenant’s share of the rent savings is $200,000.

Tenant pays the net monthly rent (or no monthly rent, as the case may be) due to landlord under the One Xxxxxxx Square Lease after accounting for the rent savings under the One Xxxxxxx Square Lease.

Assuming five months remaining in the Term under the One Xxxxxxx Square Lease, the monthly amount of the Landlord’s share of the rent savings amortized on a straight line basis over the unexpired portion of the Term under the One Xxxxxxx Square Lease is $60,000 ($300,000 ÷ 5 months).

Since the amount of the Initial Rent Abatement has been exhausted, Tenant pays the applicable monthly Rent to Landlord plus additional rent of $60,000.

In the event of any inconsistency or conflict between the numeric examples provided above and the written provisions set forth in this Section, the written text shall govern.

If Tenant fails to comply with the requirements set forth in this Section 4.2, Tenant shall be obligated to pay the applicable Base Rent. If a Rent Certificate is inaccurate or if Tenant and Landlord have failed to properly account for a previously-occurring OKS Rent Savings Event, then Tenant shall be obligated to prepare and deliver a Rent Certificate addressing such inaccuracy or failure and shall pay to Landlord the Landlord’s share of any previously Abated Base Rent or shall receive an abatement of Base Rent, as the case may be.

4.3 Additional Rent. In addition to Base Rent, Tenant agrees to pay to Landlord as additional rent (“Additional Rent”): (i) Tenant’s Share of “Operating Expenses” (as defined in Section 4.5), and (ii) any and all other amounts Tenant assumes or agrees to pay to Landlord the provisions of this Lease, including, without limitation, any and all other sums that may due by reason of any default of Tenant or failure to comply with the agreements, terms, and conditions of this Lease to be performed by Tenant, after any applicable notice and cure period.

4.4 Intentionally Omitted.

4.5 Operating Expense Payments. Landlord shall endeavor to deliver to Tenant a written estimate of Operating Expenses for each calendar year during the Term (the “Annual Estimate”) not later than November 30 of the preceding calendar year, which may be revised by Landlord from time to time during such calendar year. During each month of the Term commencing on the Lease Commencement Date, on the same date that Base Rent is due, Tenant shall pay Landlord an amount equal to 1/12th of Tenant’s Share of the Annual Estimate, for any fractional calendar month shall be prorated. If Landlord fails to give Tenant the Annual Estimate prior to the beginning of any calendar year, Tenant shall continue to pay Operating Expenses in accordance with the previous Annual Estimate, until Tenant receives a new from Landlord.

The term “Operating Expenses” means all costs and expenses of any kind or description whatsoever incurred or accrued each calendar year by Landlord in operating, maintaining, repairing, and managing the Building and the Project including, without duplication, Taxes (as defined in Section 4.5), capital repairs and improvements (1) reasonably projected to reduce the amount of Operating Expenses payable by Tenant or (2) required to comply with any Legal Requirements that first become effective and applicable to the Project after the date of this Lease, amortized over-the useful life of such capital items as determined in accordance with generally accepted accounting principles, costs for transportation services and a property management fee not to exceed 3.0% of Base Rent, excluding only:

(a) the original construction costs of the Project and renovation prior to the date of the Lease and costs of correcting defects in such original construction or renovation;

(b) capital expenses for the Project except as expressly permitted above;

(c) interest, principal and other payments pursuant to a Mortgage (as defined in Section 19.1) debts of Landlord, ground rent, financing costs and amortization of funds borrowed by Landlord, whether secured or unsecured;

(d) depreciation of the Project (except for capital improvements, the cost of which are includable in Operating Expenses);

(e) advertising, promotional, legal and space planning expenses and leasing commissions and other costs and expenses incurred in procuring and leasing space to tenants for the Project, including any leasing office maintained in the Project, free rent and construction allowances for tenants;

(f) legal and other expenses incurred in the negotiation or enforcement of leases;

(g) completing, fixturing, improving, renovating, painting, redecorating or other work, which Landlord pays for or performs for other tenants within their premises, and costs of correcting defects in such work;

(h) costs to be reimbursed by other tenants of the Project or Taxes to be paid directly by Tenant or other tenants of the Project, whether or not actually paid;

(i) The cost of any work or services performed for any other property other than the Project, including, without limitation, salaries, wages, benefits and other compensation paid to employees of Landlord who are not assigned in whole or in part to the operation, management, maintenance or repair of the Project;

(j) salaries, wages, benefits and other compensation paid to officers and executives of Landlord and administrative employees above the grade of property manager or building supervisor and Landlord’s general overhead;

(k) general organizational, administrative and overhead costs relating to maintaining Landlord’s existence, either as a corporation, partnership, or other entity, including general corporate, legal and accounting expenses;

(l) costs (including attorneys’ fees and costs of settlement, judgments and payments in lieu thereof) incurred in connection with disputes with tenants, other occupants, or prospective tenants, and costs and expenses, including legal fees, incurred in connection with negotiations or disputes with employees, consultants, management agents, leasing agents, purchasers or mortgagees of the Building;

(m) costs incurred by Landlord due to the violation by Landlord, its employees, agents or contractors or any tenant of the terms and conditions of any lease of space in the Project or any Legal Requirement (as defined in Section 1.2);

(n) penalties, fines or interest incurred as a result of Landlord’s inability or failure to make payment of Taxes and/or to file any tax or informational returns when due, or from Landlord’s failure to make any payment of Taxes required to be made by Landlord hereunder before delinquency;

(o) overhead and profit increment paid to Landlord or to subsidiaries or affiliates of Landlord for goods and/or services in or to the Project to the extent the same exceeds the costs of such goods and/or services rendered by unaffiliated third parties on a competitive basis;

(p) costs of Landlord’s charitable or political contributions, or of fine art maintained at the Project;

(q) costs in connection with services (including electricity), items or other benefits of a type which are not standard for the Project and which are not available to Tenant without specific charges therefor, but which are provided to another tenant or occupant of the Project, whether or not such other tenant or occupant is specifically charged therefor by Landlord;

(r) costs incurred in the sale or refinancing of the Project;

(s) costs for remediation, abatement, removal or encapsulation of Hazardous Materials at the Project other than routine cleaning and maintenance which may involve the same;

(t) net income taxes of Landlord or the owner of any interest in the Project, franchise, capital stock, gift, estate or inheritance taxes or any federal, state or local documentary taxes imposed against the Project or any portion thereof or interest therein; and

(u) any expenses otherwise includable within Operating Expenses to the extent actually reimbursed by persons other than tenants of the Project under leases for space in the Project.

Within 90 days after the end of each calendar year, Landlord shall furnish to Tenant a statement (an “Annual Statement”) showing in reasonable detail: (a) the total and Tenant’s Share of actual Operating Expenses for the previous calendar year, and (b) the total of Tenant’s payments in respect of Operating Expenses for such year. If Tenant’s Share of actual Operating Expenses for such year exceeds Tenant’s payments of Operating Expenses for such year, the excess shall be due and payable by Tenant as Rent within 30 days after delivery of such Annual Statement to Tenant. If Tenant’s payments of Operating Expenses for such year exceed Tenant’s Share of actual Operating Expenses for such year, the excess shall be credited against the next due amounts of Rent, provided that any overpayment shall be paid to Tenant within thirty (30) days if the Term has ended, provided that if Tenant is delinquent in its obligation to pay Base Rent or Additional Rent, Landlord shall pay the excess to Tenant after deducting all other amounts due Landlord.

The Annual Statement shall be final and binding upon Tenant unless Tenant, within 60 days after Tenant’s receipt thereof, shall contest any item therein by giving written notice to Landlord, specifying each item contested and the reason therefor. If, during such 60 day period, Tenant reasonably and in good faith questions or contests the accuracy of Landlord’s statement of Tenant’s Share of Operating Expenses, provided that Tenant pays any amount due on the Annual Statement if applicable, Landlord will provide Tenant with access to Landlord’s books and records relating to the operation of the Project and such information as Landlord reasonably determines to be responsive to Tenant’s questions (the “Expense Information”). If Landlord and Tenant cannot agree upon the amount of Tenant’s Share of Operating Expenses within thirty (30) days after Tenant’s review of such Expense Information, then Tenant shall have the right to have an independent public accounting firm selected by Tenant, working pursuant to a fee arrangement other than a contingent fee (at Tenant’s sole cost and expense) and approved by Landlord (which approval shall not be unreasonably withheld or delayed), audit and/or review the Expense Information for the year in question (the “Independent Review”). The results of any such Independent Review shall be binding on Landlord and Tenant. If the Independent Review shows that the payments actually made by Tenant with respect to Operating Expenses for the calendar year in question exceeded Tenant’s Share of Operating Expenses for such calendar year, Landlord shall at Landlord’s option either (i) credit the excess amount to the next succeeding installments of estimated Operating Expenses or (ii) pay the excess to Tenant within 30 days after delivery of such statement, except that after the expiration or earlier termination of this Lease or if Tenant is delinquent in its obligation to pay Rent, Landlord shall pay the excess to Tenant after deducting all other amounts due Landlord. If the Independent Review shows that Tenant’s payments with respect to Operating Expenses for such calendar year were less than Tenant’s Share of Operating Expenses for the calendar year, Tenant shall pay the deficiency to Landlord within 30 days after delivery of such statement. If the Independent Review shows that Tenant has overpaid with respect to Operating Expenses stated in the Annual Statement or any adjustments made thereafter by more than 5% then Landlord shall reimburse Tenant for all costs incurred by Tenant for the Independent Review. Operating Expenses for the calendar years in which Tenant’s obligation to share therein begins and ends shall be prorated. Notwithstanding anything set forth herein to the contrary, if the Project is not at least 95% occupied on average during any year of the Term, Tenant’s Share of Operating Expenses that vary according to occupancy of the Project for such year shall be computed as though the Project had been 95% occupied on average during such year.

“Tenant’s Share” shall be the percentage set forth on the first page of this Lease as Tenant’s Share as reasonably adjusted by Landlord for changes in the physical size of the Premises or the Project occurring thereafter. Landlord may equitably adjust Tenant’s Share for any item of expense or cost reimbursable by Tenant that relates to a repair, replacement, or service that benefits only the Premises or only a portion of the Project that includes the Premises, which adjustment may be reviewed by Tenant as part of the Independent Review. Base Rent, Tenant’s Share of Operating Expenses and all other amounts payable by Tenant to Landlord hereunder are collectively referred to herein as “Rent.”

4.6 Taxes. Tenant shall pay, as part of Operating Expenses, all taxes, levies, fees, assessments and governmental charges of any kind, existing as of the Lease Commencement or thereafter enacted (collectively referred to as “Taxes”), imposed by any federal, state, municipal, local or other governmental authority or agency, including, without limitation, quasi-quasi-public agencies (collectively, “Governmental Authority”) during the Term, including,

without limitation, all Taxes: (i) imposed on or measured by or based, in whole or in part, on payable to (or gross receipts received by) Landlord under this Lease and/or from the rental by Landlord of the Project or any portion thereof, or (ii) based on the square footage, assessed value or other measure or evaluation of any kind of the Premises or the Project, or (iii) assessed or imposed by or on the operation or maintenance of any portion of the Premises or the Project, including parking, or (iv) assessed or imposed by, or at the direction of, or resulting from Legal Requirements, or interpretations thereof, promulgated by any Governmental Authority, or (v) imposed as a license or other fee, charge, tax, or assessment on Landlord’s business or of leasing space in the Project. The prorated portion of any Taxes that are due and payable pertaining to periods prior to the Lease Commencement Date or after the expiration of the Term shall not be Tenant’s obligation to pay hereunder. Landlord may contest by appropriate legal proceedings the amount, validity, or application of any Taxes or liens securing Taxes. If a in Taxes is obtained for any year of the Term during which Tenant paid Tenant’s Share of Taxes, then Taxes for that year will be retroactively adjusted and Landlord shall provide Tenant with a credit, if any, based on the adjustment. Taxes shall not include any net income taxes imposed on Landlord except to the extent such net income taxes are in substitution for any Taxes payable hereunder. If any such Tax is levied or assessed directly against Tenant, then Tenant shall be responsible for and shall pay the same at such times and in such manner as the taxing authority shall require. Tenant shall pay, prior to delinquency, any and all Taxes levied or assessed against any personal property or trade fixtures placed by Tenant in the Premises, whether levied or assessed against Landlord or Tenant. If any Taxes on Tenant’s personal property or trade are levied against Landlord or Landlord’s property, or if the assessed valuation of the Project is expressly increased by the taxing authority by a value attributable to improvements in or alterations to the Premises, whether owned by Landlord or Tenant and whether or not affixed to the real property so as to become a part thereof, higher than the base valuation on which from time-to-time allocates Taxes to all tenants in the Project, Landlord shall have the right, but not the obligation, to pay such Taxes. Landlord’s determination of any excess assessed valuation shall be binding and conclusive, absent manifest error. The amount of any such payment by Landlord shall constitute Additional Rent due from Tenant to Landlord immediately upon demand.

ARTICLE 5

CONDITION OF PREMISES; CONSTRUCTION

5.1 Base Building Work.

(a) Landlord shall deliver the Premises to Tenant upon the Effective Date with the work (“Landlord’s Work”) more particularly described in the base building specifications attached hereto as Exhibit F (“Base Building Specifications”) completed. Landlord’s Work comply with the Legal Requirements and shall be consistent with Class A standards for and office space, and substantially in conformance with, and not materially inconsistent with, the Base Building Specifications. Landlord shall deliver the Premises to Tenant with all base systems, including, but not limited to, HVAC, electrical, life safety and plumbing systems in working order, in compliance with applicable Legal Requirements and suitable for laboratory purposes. The allocation of the responsibilities between the Landlord’s Work and Tenant’s Work set forth on the Landlord/Tenant Matrix attached hereto as Exhibit G (“Landlord/Tenant Matrix”).

(b) Tenant agrees (i) except as otherwise provided herein to the contrary, to accept possession of the Premises in the condition described in the Base Building Specifications and otherwise in “as is” condition, (ii) that neither Landlord nor Landlord’s agents have made any representations or warranties with respect to the Premises or the Building except as provided herein, and (iii) Landlord has no obligation to perform any work, supply any materials, incur any expense or make any alterations, additions or improvements to the Premises to prepare the Premises for Tenant’s use and occupancy except as provided herein. Landlord will remedy any defect in workmanship, materials or equipment furnished by Landlord pursuant to this Section, excluding reasonable wear and tear and improper use by Tenant, provided Tenant notifies Landlord of the defect within 12 months after the Lease Commencement Date.

5.2 Tenant’s Work.

(a) Tenant shall prepare, at its sole cost and expense (against which the Landlord’s Contribution may be applied), a set of design/development plans in conformance with the concept plan approved by Landlord (subject to Landlord’s review of further details regarding access, maintenance and ventilation issues in connection with the cold room located on the second floor along the window line) and attached hereto as Exhibit H, Tenant Design and Construction Guidelines attached hereto as Exhibit I (“Tenant Design and Construction Guidelines”) and the allocation of responsibilities set forth in the Landlord/Tenant Matrix sufficient for Landlord to approve Tenant’s proposed design of the Premises (“Design/Development Plans”), and a full set of final permit-ready construction drawings (“Final Construction Drawings”) for the interior finish and layout of the initial improvements (“Tenant’s Work”) which Tenant desires to have performed in the Premises. The Design/Development Plans and the Final Construction Drawings are collectively referred to herein as the “Plans.” Provided that no Default has occurred and remains outstanding, Landlord shall reimburse Tenant up to $6,159.10 ($.10 per RSF) for out of pocket costs incurred in preparing the initial test fit of the Premises.

(b) The Plans shall be submitted to Landlord, together with a construction budget setting forth the anticipated costs for the Tenant’s Work, and Landlord shall approve or disapprove of the Plans, which approval shall not be unreasonably withheld, conditioned or delayed, and Landlord shall respond in any event within fifteen (15) days of receiving them. No work shall be conducted by or on behalf of Tenant until the Final Construction Drawings have been approved for such work in writing by Landlord. At Tenant’s sole cost and expense (against which the Landlord’s Contribution may be applied), Tenant shall cause the Plans to be revised in manner sufficient to remedy the Landlord’s reasonable objections and/or respond to the reasonable concerns and for such revised Plans to be redelivered to Landlord, and Landlord shall approve or disapprove such portions of the Plans to which Landlord previously commented seven (7) days following the date of resubmission. Landlord may not disapprove anything on a set of Plans which it has previously approved in an earlier set of Plans unless new revealed by the applicable later iteration of Tenant’s Plans provides Landlord with a reasonable basis for doing so. Landlord’s failure to timely respond to Tenant’s submitted Plans or revised Plans shall be deemed to be approval thereof provided that upon submitting such plans, Tenant provides written notice to Landlord stating “IF LANDLORD FAILS TO RESPOND TO THE ENCLOSED PLANS WITHIN 15 DAYS (OR 7 DAYS AS APPLICABLE), LANDLORD’S APPROVAL SHALL BE DEEMED GIVEN PURSUANT TO SECTION 5.2(b) OF THE LEASE” in upper case boldface type in the top margin of such notice. Landlord’s approval is solely given for the benefit of Landlord and Tenant under this Section and neither Tenant nor any third party shall have the right to rely upon Landlord’s approval of the Plans for any other whatsoever.

(c) Landlord shall not charge Tenant any coordination, overhead or contractor supervision fees in connection with Tenant’s Work; provided, however that Landlord shall be reimbursed from the Landlord’s Contribution for any reasonable third-party, out of pocket expenses incurred by Landlord in connection with the review and approval of Tenant’s Work.

(d) The Plans shall be stamped by a Massachusetts registered architect and engineer, such architect and engineer and Tenant’s general contractor and subcontractors, being subject to Landlord’s prior approval, which shall not be unreasonably withheld, conditioned or delayed, and shall comply with the Legal Requirements and the requirements of the Tenant Design and Construction Guidelines. The final approved Plans shall be in a form satisfactory to appropriate governmental authorities responsible for issuing permits, approvals and licenses required for Tenant’s Work.

(e) Tenant’s Work shall be completed in accordance with the Plans and no material changes to Tenant’s Work shall occur without Landlord’s approval as set forth herein. All of the Tenant’s Work shall be performed in accordance with the requirements set forth in the Tenant Design and Construction Guidelines and completed in a first class workmanlike manner. Tenant shall be solely responsible for the effect of the Tenant’s Work on the Building’s structure and systems, whether or not Landlord has consented to the Alterations, and shall reimburse Landlord on demand for any costs incurred by Landlord that can be demonstrated by clear evidence to have been caused by reason of any faulty work done by Tenant or its contractors. All of Tenant’s Work shall be performed in such manner as to maintain harmonious labor relations and to minimize any material interference with Building operations.

(f) Tenant shall use diligent efforts to keep the Project and Tenant’s leasehold interest therein free of any liens or claims of liens arising from acts or omissions of Tenant, or its subtenants, contractors or others claiming by, through or under Tenant, and shall discharge or bond any such liens within ten (10) Business Days following notice to Tenant of their filing. Tenant shall provide evidence of such insurance as Landlord may reasonably require, naming Landlord as an additional insured. Tenant shall indemnify Landlord and hold it harmless from and against any cost, claim, or liability arising from any work done by or at the direction of Tenant.

(g) All alterations affixed to the Premises shall become part thereof and therein at the end of the Term. However, if Landlord gives Tenant a notice, at the time Landlord approves the Plans, to remove any alterations, Tenant shall do so and shall pay the cost of and any repair required by such removal. Notwithstanding the foregoing, within four weeks after the expiration or earlier termination of the Term of the Lease and provided that Tenant continues pay the periodic Rent obligation pending completion of the work, Tenant shall remove the stairwell shown on the Plans and installed as part of Tenant’s Work and restore the applicable to the condition existing as of the Effective Date. Tenant may elect to have Landlord perform stairwell infill restoration work at Tenant’s cost (in which case, no Rent shall be due Landlord assuming that Tenant is not otherwise is in possession of the Premises) upon written notice to Landlord at least six months prior to the expiration of the Term. If Tenant makes such election,

Landlord will solicit at least three bids from contractors at least four months prior to the of the Term. Landlord will choose the lowest qualified bidder and arrange for such restoration work to be performed at Tenant’s cost within four weeks after the expiration or earlier of the Term of the Lease. Notwithstanding the foregoing, if Landlord has entered into a lease agreement with a tenant that desires that the stairwell remains in place, Tenant shall not be obligated to remove the staircase or pay for Landlord to do so.

(h) All of Tenant’s personal property, trade fixtures, equipment, furniture, movable partitions, and any alterations not affixed to the Premises shall remain Tenant’s property, removable at any time. If Tenant fails to remove any such materials at the end of the Term, Landlord may do so and store them at Tenant’s expense, without liability to Tenant, and may sell them at public or private sale and apply the proceeds to any amounts due hereunder, including costs of removal, storage and sale.

(i) Tenant desires to achieve a LEED Gold Certification for Tenant’s Work from the United States Green Building Council. Upon Tenant’s request, Landlord shall cooperate with such process and provide all information and documentation reasonably required in connection therewith provided that such cooperation shall not cause Landlord to incur any cost or liability including, without limitation, required modifications to Landlord’s Work. Nothing contained herein shall be construed as a warranty or guaranty that Tenant’s aspirational LEED certification will necessarily be achieved or maintained.

5.3 Intentionally Deleted.

5.4 Landlord’s Contribution. (a) As an inducement to Tenant’s entering into this Lease, Landlord shall, subject to the terms set forth in this Section, provide to Tenant a special tenant improvement allowance for the actual costs incurred with respect to the hard and soft of design and performance of the Tenant’s Work (including without limitation, architectural and engineering fees, project management fees, signage expenses, data/telecom cabling and security) up to a maximum aggregate amount of Nine Million Two Hundred Thirty Eight Thousand Six Hundred Fifty and 00/100 Dollars ($9,238,650.00) [$150.00 per RSF] less any past due expenses owed to Landlord by Tenant under this Lease (“Initial Allowance”).

(b) As a further inducement to Tenant’s entering into this Lease, upon Tenant’s written request prior to Tenant’s submission of the Final Construction Drawings to Landlord for Landlord’s approval in accordance with Section 5.2(b), Landlord shall provide an additional allowance to fund such excess costs (which costs may include, without limitation, costs in connection with design and construction costs and expenses) up to a maximum aggregate amount of One Million Two Hundred Thirty One Eight Hundred Twenty and 00/100 Dollars ($1,231,820.00) [$20.00 per RSF] less any past due expenses owed to Landlord by Tenant under this Lease (“Additional Allowance”) (the Initial Allowance and the Additional Allowance, are hereinafter referred to, singly or collectively, as the “Landlord’s Contribution”).

(c) If the Additional Allowance is provided, commencing on the Rent Commencement Date, Tenant shall pay Landlord as additional rent the monthly installment of amortization of the Additional Allowance actually disbursed by Landlord in an amount sufficient to fully amortize the funded amount of the Additional Allowance over the unexpired portion of Base Term on a direct reduction basis payable in equal monthly installments including interest at the annual rate of eight percent (8%).

(d) Landlord shall pay to Tenant an amount not to exceed Landlord’s Contribution to the extent permitted pursuant to this Section, provided that as of the date on which Landlord is required to make payment thereof pursuant to this Section: (i) this Lease is in full force and effect, and (ii) no Event of Default then exists. Tenant shall pay all costs of the Tenant’s Work in excess of Landlord’s Contribution. Each funded requisition for Landlord’s Contribution shall be applied first on account of any hard construction costs and labor directly related to the Tenant’s Work and materials delivered to the Building in connection with the Tenant’s Work, and then, second on account of any soft construction costs or design fees. Upon the completion of the Tenant’s Work and acquisition of Tenant’s furniture, fixtures and equipment and satisfaction of the conditions set forth in this Section, any amount of Landlord’s Contribution which has not been previously requisitioned may be applied to reimburse Tenant for out of pocket relocation expenses and furniture, fixtures and equipment.

(e) Landlord shall make progress payments on account of Landlord’s Contribution to Tenant on a monthly basis, for the work performed during the previous month, less such retainage (“Retainage”) as is provided for in Tenant’s construction contract(s) and contracts for the purchase and delivery of furniture, fixtures and equipment, provided that such contracts shall require Retainage of not less than five percent (5%) of the total contract price (in the aggregate) (which 5% Retainage shall not be in addition to the amounts retained under such contracts).

(f) Landlord shall pay Landlord’s Proportion (hereinafter defined) of the cost shown on each requisition submitted by Tenant to Landlord until the entirety of Landlord’s Contribution has been exhausted. “Landlord’s Proportion” shall be a fraction, the numerator of which is Landlord’s Contribution and the denominator of which is the total contract price for Tenant’s Work (as evidenced by reasonably detailed documentation delivered to Landlord with the requisition first submitted by Tenant).

(g) Landlord’s progress payments shall be made payable directly to Tenant or, upon Tenant’s written request, to Tenant’s general contractor, within thirty (30) days following delivery to Landlord of requisitions therefor. Landlord shall have the right, upon reasonable advance notice to Tenant, to inspect Tenant’s books and records relating to each requisition in to verify the amount thereof. Tenant shall submit requisition(s) no more often than monthly, such requisition shall be executed by a duly authorized officer of Tenant, and shall be by (i) with the exception of the first requisition, copies of partial waivers of lien from all contractors, subcontractors, and material suppliers covering all work and materials which were subject of previous progress payments by Landlord and Tenant, (ii) a certification from Tenant’s architect on a completed AIA Form G702, and (iii) a requisition certificate on a completed AIA Form G703. Landlord shall hold such Retainage and disburse the Retainage, or portions thereof requisitioned by Tenant from time to time on account of subcontractors who have completed respective portions of the job, upon submission by Tenant to Landlord of Tenant’s requisition therefor accompanied by all documentation required under the foregoing provisions of this Section, together with (A) proof of the satisfactory completion of all required inspections and issuance of any required approvals, permits and sign offs for the work of such subcontractor, or

with respect to the work of the Tenant’s general contractor, the Tenant’s Work, by Governmental Authorities having jurisdiction thereover (including issuance of the Certificate of Occupancy) (“Substantial Completion of Tenant’s Work”), and (B) issuance of final lien waivers by all contractors, subcontractors and material suppliers covering all of the Tenant’s Work or the thereof as applicable (which final lien waivers may be conditioned upon, or delivered concurrent with, payment of such Retainage). If Tenant fails to pay to Tenant’s contractors the amounts paid by Landlord to Tenant in connection with any previous requisition(s), Landlord shall thereafter have the right to have Landlord’s Contribution paid directly to Tenant’s contractors. In addition, concurrent with the final requisition for the Retainage, Tenant shall submit “as-built” plans and specifications for the Tenant’s Work. The right to receive Landlord’s Contribution is for the exclusive benefit of Tenant, and in no event shall such right be assigned to or be enforceable by for the benefit of any third party, including any contractor, subcontractor, materialman, laborer, architect, engineer, attorney or other person or entity (excepting only to a permitted assignee of this Lease pursuant to Article 17).

If Landlord fails to fund Landlord’s Contribution notwithstanding Tenant’s compliance with the foregoing conditions, within thirty (30) days after Tenant’s written demand, the unfunded amount of the Landlord’s Contribution shall accrue interest at the Default Rate from the date due until paid, and Tenant may offset such owed amounts from subsequent installments of Rent which abatement shall be applied up to a maximum of seventy five percent (75%) of each monthly installment of Rent until the total cost incurred by Tenant is reimbursed.

5.5 Measurement of Premises.

If requested by Tenant, the Premises shall be measured according to the BOMA Standard Method for Measuring Floor Area in Office Buildings, modified as is customary for laboratory buildings in the Boston/Cambridge area market, to include mechanical shafts dedicated solely to tenant use in the tenant rentable area. The following are expressly excluded from the measurement of the Premises and reserved to Landlord: all the perimeter walls of the Premises (except the inner surfaces thereof), the Common Areas, and any space in or adjacent to the Premises used for shafts, stacks, pipes, conduits, wires and appurtenant fixtures, fan rooms, ducts, electric or other utilities, sinks or other Building facilities, and the use of all of the foregoing. If the measurement of the Premises determines that the area of the Premises is greater or less than ten percent (10%) of the area of the Premises set forth in Section 1.1 hereof, then whenever the size of the Premises is necessary for any computation, size shall be the adjusted size as herein determined.

ARTICLE 6

USE

6.1 Use. The Premises shall be used solely for the Permitted Use set forth in the basic lease provisions in Section 1.1 of this Lease, and in compliance with all Legal Requirements now or hereafter applicable to the Premises, and to the use and occupancy thereof, including, without limitation, the Americans With Disabilities Act, 42 U.S.C. § 12101, et seq. (together with the regulations promulgated pursuant thereto, “ADA”). Tenant shall, upon 5 days’ written notice Landlord, discontinue any use of the Premises which is declared by any Governmental Authority (as defined in Section 4.6) having jurisdiction to be a violation of a Legal Requirement. Tenant not use or permit the Premises to be used for any purpose or in any manner that would void

Landlord reserves the right from time to time to require Tenant to obtain higher minimum amounts of commercial general liability insurance or reduced deductible amounts (based on Landlord’s reasonable review of Tenant’s ability to pay anticipated claims) to conform with requirements of Landlord’s lender and/or to bring coverage limits to levels then being generally required of new tenants within the Project or customarily required for similar projects. Tenant shall deliver a certificate of all such insurance and receipts evidencing payment therefor (and, upon request, copies of all required insurance policies, including endorsements and declarations) to Landlord on or before the Effective Date and at such other times as Landlord may request (and pending such delivery of the insurance certificate, Landlord may defer commencement of the Tenant’s Work).

(e) Tenant hereby waives and releases Landlord and the holder of any mortgage from any and all liabilities, claims and losses for damage to property for which Landlord is or may otherwise be held liable to the extent Tenant either is required to maintain property insurance pursuant to this Article with respect to the property so damaged, or receives insurance proceeds on account thereof. Landlord hereby waives and releases Tenant from any and all liabilities, claims and losses for damage to property for which Tenant is or may be otherwise held liable to the extent Landlord either is required to maintain property insurance pursuant to this Article with respect to the property so damaged, or receives insurance proceeds on account thereof. In the case of the all-risk property insurance, both parties shall secure waiver of subrogation endorsements from their respective insurance carriers as to the other party.

ARTICLE 14

RESTORATION

14.1 Restoration. If, at any time during the Term, the Project or the Premises are damaged or destroyed by a fire or other insured casualty, Landlord shall notify Tenant within 30 days after discovery of such damage as to the amount of time Landlord reasonably estimates it take to restore the Project or the Premises, as applicable (the “Restoration Period”). If the Restoration Period is reasonably estimated to exceed 9 months (the “Maximum Restoration Period”), Landlord may, in such notice, elect to terminate this Lease as of the date that is 45 after the date of discovery of such damage or destruction. Notwithstanding Landlord’s election restore, Tenant may elect to terminate this Lease by written notice to Landlord delivered within Business Days of receipt of a notice from Landlord estimating a Restoration Period for the Premises longer than the Maximum Restoration Period. Unless either Landlord or Tenant so to terminate this Lease, Landlord shall, subject to receipt of sufficient insurance proceeds (with any deductible to be treated as a current Operating Expense), promptly restore the Premises (including Landlord’s Work and Tenant’s Work, but excluding the improvements installed by Tenant or by Landlord and paid for by Tenant), subject to delays arising from the collection of insurance proceeds, from Force Majeure events or as needed to obtain any license, clearance or other authorization of any kind required to enter into and restore the Premises issued by any Governmental Authority having jurisdiction over the use, storage, handling, treatment, release, disposal, removal or remediation of Hazardous Materials in, on or about the Premises (collectively referred to herein as “Hazardous Materials Clearances”); provided, however, that if repair or restoration of the Premises is not substantially complete as of the end of the Restoration Period or, if longer, the Restoration Period, Tenant may elect, by written notice to Landlord, to terminate this Lease, in which event Landlord shall be relieved of its obligation to make such repairs or restoration and this Lease shall terminate as of the date that is 75 days after the later of: (i) discovery of such damage or destruction, or (ii) the date all required Hazardous Materials Clearances are obtained, but Landlord shall retain any Rent paid and the right to any Rent payable by Tenant prior to such election by Tenant.

Tenant, at its expense, shall promptly perform, subject to delays arising from the collection of insurance proceeds, from Force Majeure (as defined in Section 30.20) events or to obtain Hazardous Material Clearances, all repairs or restoration deemed necessary by Tenant in accordance with its then current operations and not required to be done by Landlord and shall promptly re-enter the Premises and commence doing business in accordance with this Lease. Rent shall be abated from the date of such casualty until the Premises are repaired and restored, in the proportion which the area of the Premises, if any, which is not usable by Tenant bears to the total area of the Premises. Such abatement shall be the sole remedy of Tenant, and except as provided in this Section, Tenant waives any right to terminate the Lease by reason of damage or casualty loss.

Notwithstanding the foregoing, either party may terminate this Lease if the Premises are damaged during the last year of the Term and Landlord reasonably estimates that it will take more than two months to repair such damage, or if insurance proceeds are not available for such restoration.

The provisions of this Lease, including this Section, constitute an express agreement between Landlord and Tenant with respect to any and all damage to, or destruction of, all or any part of the Premises, or any other portion of the Project, and any statute or regulation which is now or may hereafter be in effect shall have no application to this Lease or any damage or destruction to all or any part of the Premises or any other portion of the Project, the parties hereto expressly agreeing that this Section sets forth their entire understanding and agreement with respect to such matters.

ARTICLE 15

CONDEMNATION

15.1 Condemnation. If the whole or any material part of the Premises or the Project is taken for any public or quasi-public use under governmental law, ordinance, or regulation, or by right of eminent domain, or by private purchase in lieu thereof (a “Taking” or “Taken”), and the Taking would in Landlord’s reasonable judgment, either prevent or materially interfere with Tenant’s use of the Premises or materially interfere with or impair Landlord’s ownership or operation of the Project, then upon written notice by Landlord this Lease shall terminate and shall be apportioned as of said date. In addition, if a Taking of the whole or any material part of Premises or the Project would in the reasonable judgment of Tenant either prevent or materially interfere with Tenant’s use of the Premises, Tenant shall have the right to terminate this Lease by written notice to Landlord within thirty (30) days of the date that Landlord’s title has been of such property. If part of the Premises shall be Taken, and this Lease is not terminated as provided above, Landlord shall promptly restore the Premises and the Project as nearly as is commercially reasonable under the circumstances to their condition prior to such partial Taking and the rentable square footage of the Building, the rentable square footage of the Premises, Tenant’s Share of Operating Expenses and the Rent payable hereunder during the unexpired shall be reduced to such extent as may be fair and reasonable under the circumstances. Upon any such Taking, Landlord shall be entitled to receive the entire price or award from any such Taking without any payment to Tenant, and Tenant hereby assigns to Landlord Tenant’s interest, if any, such award. Tenant shall have the right, to the extent that same shall not diminish Landlord’s award, to make a separate claim against the condemning authority (but not Landlord) for such compensation as may be separately awarded or recoverable by Tenant for moving expenses and damage to Tenant’s trade fixtures, if a separate award for such items is made to Tenant. Tenant hereby waives any and all rights it might otherwise have pursuant to any provision of state law to terminate this Lease upon a partial Taking of the Premises or the Project.

ARTICLE 16

EVENTS OF DEFAULT

16.1 Events of Default. Each of the following events shall be a default (“Default”) by Tenant under this Lease:

(a) Payment Defaults. Tenant shall fail to pay any installment of Rent or any other payment hereunder when due and such default shall continue for more than five (5) Business Days after written notice from Landlord.

(b) Insurance. Any insurance required to be maintained by Tenant pursuant to this Lease shall be canceled or terminated or shall expire or shall be reduced or materially changed and Tenant shall fail to replace such insurance before the expiration of the current coverage.

(c) Improper Transfer. Tenant shall assign, sublease or otherwise transfer all or any portion of Tenant’s interest in this Lease or the Premises except as expressly permitted herein, or Tenant’s interest in this Lease shall be attached, executed upon, or otherwise judicially seized and such action is not released within 90 days of the action.

(d) Liens. Tenant shall fail to discharge or otherwise obtain the release of any lien placed upon the Premises in violation of this Lease within 15 days after written notice from Landlord.

(e) Insolvency Events. Tenant or any guarantor or surety of Tenant’s obligations hereunder shall: (A) make a general assignment for the benefit of creditors; (B) commence any case, proceeding or other action seeking to have an order for relief entered on its behalf as a debtor or to adjudicate it a bankrupt or insolvent, or seeking reorganization, arrangement, adjustment, liquidation, dissolution or composition of it or its debts or seeking appointment of a receiver, trustee, custodian or other similar official for it or for all or of any substantial part of its property (collectively a “Proceeding for Relief”); (C) become the subject of any Proceeding for Relief which is not dismissed within 90 days of its filing or entry; or (D) die or suffer a legal disability (if Tenant, guarantor, or surety is an individual) or be dissolved or otherwise fail to maintain its legal existence (if Tenant, guarantor or surety is a corporation, partnership or other entity).

(f) Estoppel Certificate or Subordination Agreement. Tenant fails to execute any document required from Tenant under Article 18 or 19 within 5 Business Days after a second notice requesting such document.

(g) Swing Space Lease. A “Default of Tenant” (as defined in the Swing Space Lease) occurs under the Swing Space Lease.

(h) Other Defaults. Tenant shall fail to comply with any provision of this Lease other than those specifically referred to in this Section, and, except as otherwise expressly provided herein, such failure shall continue for a period of 30 days after written notice thereof from Landlord to Tenant.

Any notice given pursuant to this Section hereof shall: (i) specify the alleged default, (ii) demand that Tenant cure such default, (iii) be in lieu of, and not in addition to, or shall be deemed to be, any notice required under any provision of applicable law, and (iv) not be deemed a forfeiture or a termination of this Lease unless Landlord elects otherwise in such notice; provided that if the nature of Tenant’s default pursuant to this Section is such that it cannot be cured by the payment of money and reasonably requires more than 30 days to cure, then Tenant shall not be deemed to be in default if Tenant commences such cure within said 30 day period and thereafter diligently prosecutes the same to completion; provided, however, that such cure shall be completed no later than 90 days from the date of Landlord’s notice.

16.2 Landlord’s Remedies.

(a) Payment By Landlord; Interest. Upon a Default by Tenant hereunder, Landlord may, without waiving or releasing any obligation of Tenant hereunder, make such payment or perform such act. All sums so paid or incurred by Landlord, together with interest thereon, from the date such sums were paid or incurred, at the Default Rate, shall be payable to Landlord on demand as Additional Rent.

(b) Late Payment Rent. Late payment by Tenant to Landlord of Rent and other sums due will cause Landlord to incur costs not contemplated by this Lease, the exact amount of which will be extremely difficult and impracticable to ascertain. Such costs include, but are not limited to, processing and accounting charges and late charges which may be imposed on Landlord under any Mortgage covering the Premises. Therefore, if any installment of Rent due from Tenant is not received by Landlord within 5 days after the date such payment is due more than once in any eighteen month period, Tenant shall pay to Landlord an additional sum equal to 5% of the overdue Rent as a late charge. The parties agree that this late charge represents a fair and reasonable estimate of the costs Landlord will incur by reason of late payment by Tenant. In addition to the late charge, Rent not paid when due shall bear interest at the Default Rate from the 5th day after the date due until paid.

(c) Remedies. Upon the occurrence of a Default, Landlord, at its option, without further notice or demand to Tenant, shall have in addition to all other rights and remedies provided in this Lease, at law or in equity, the option to pursue any one or more of the following remedies, each and all of which shall be cumulative and nonexclusive, without any notice or demand whatsoever.

(i) Terminate this Lease, or at Landlord’s option, Tenant’s right to possession only, in which event Tenant shall immediately surrender the Premises to Landlord, and if Tenant fails to do so, Landlord may, without prejudice to any other remedy which it may have for possession or arrearages in rent, enter upon and take possession of the Premises in compliance with applicable Legal Requirements and expel or remove Tenant and any other person who may be occupying the Premises or any part thereof, without being liable for prosecution or any claim for damages therefor unless such process is accomplished by Landlord in violation of applicable Legal Requirements;

(ii) Upon any termination of this Lease, whether pursuant to the foregoing subsection (i) or otherwise, Landlord may recover from Tenant the following:

(A) The worth at the time of award of any unpaid Rent which has been earned at the time of such termination; plus

(B) The worth at the time of award of the amount by which the unpaid Rent which would have been earned after termination until the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus

(C) The worth at the time of award of the amount by which the unpaid Rent for the balance of the Term after the time of award exceeds amount of such rental loss that Tenant proves could have been reasonably avoided; plus

(D) Any other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant’s failure to perform its obligations under this Lease or which in the ordinary course of things would be likely to result therefrom, specifically including, but not limited to, brokerage commissions and advertising expenses incurred, expenses of remodeling the Premises or any portion thereof for a new tenant, whether for the same or a different use, and any special concessions made to obtain a new tenant; and

(E) At Landlord’s election, such other amounts in addition to or in lieu of the foregoing as may be permitted from time to time by applicable law.

As used in the foregoing subsection (c)(ii) (A) and (B), the “worth at the time of award” shall be computed by allowing interest at the Default Rate. As used in subsection (c)(ii)(C) above, the “worth at the time of award” shall be computed by discounting such amount at the discount rate of the Federal Reserve Bank of Boston at the time of award plus 1%.

(iii) Landlord may continue this Lease in effect after Tenant’s Default and recover Rent as it becomes due (Landlord and Tenant hereby agreeing that Tenant has the right to sublet or assign hereunder, subject only to reasonable limitations). Accordingly, if Landlord does not elect to terminate this Lease following a Default by Tenant, Landlord may, from time to time, without terminating this Lease, enforce all of its rights and remedies hereunder, including the right to recover all Rent as it becomes due.

(iv) Intentionally Deleted.

(v) Independent of the exercise of any other remedy of Landlord hereunder or under applicable law, upon the occurrence of a monetary Default or Default pertaining to Tenant’s failure to comply with the requirements of Article 21, Landlord may conduct an environmental test of the Premises as generally described in Section 21.4 hereof, at Tenant’s expense.

Notwithstanding anything to the contrary contained herein, in no event shall Tenant ever be liable to Landlord for any special, indirect, consequential or punitive damages under this Lease except as may arise in connection with Tenant’s holding over of the Premises as set forth in Article 25.

(d) Effect of Exercise. Exercise by Landlord of any remedies hereunder or otherwise available shall not be deemed to be an acceptance of surrender of the Premises and/or termination of this Lease by Landlord, it being understood that such surrender and/or termination can be effected only by the express written agreement of Landlord and Tenant. Any law, usage, custom to the contrary notwithstanding, Landlord shall have the right at all times to enforce the provisions of this Lease in strict accordance with the terms hereof; and the failure of Landlord at

any time to enforce its rights under this Lease strictly in accordance with same shall not be construed as having created a custom in any way or manner contrary to the specific terms, provisions, and covenants of this Lease or as having modified the same and shall not be deemed waiver of Landlord’s right to enforce one or more of its rights in connection with any subsequent default. A receipt by Landlord of Rent or other payment with knowledge of the breach of any covenant hereof shall not be deemed a waiver of such breach, and no waiver by Landlord of any provision of this Lease shall be deemed to have been made unless expressed in writing and by Landlord. To the greatest extent permitted by law, Tenant waives all right of redemption in Tenant shall be dispossessed by a judgment or by warrant of any court or judge. Any reletting of the Premises or any portion thereof shall be on such terms and conditions as Landlord in its sole discretion may determine. Landlord shall not be liable for, nor shall Tenant’s obligations hereunder be diminished because of, Landlord’s failure to relet the Premises or collect rent due in respect of such reletting or otherwise to mitigate any damages arising by reason of Tenant’s Default. Landlord shall use commercially reasonable efforts to mitigate its damages following termination of this Lease.

ARTICLE 17

ASSIGNMENT AND SUBLETTING

17.1 General Prohibition. Without Landlord’s prior written consent which shall not be unreasonably withheld, conditioned or delayed subject to and on the conditions described in this Section, Tenant shall not, directly or indirectly, voluntarily or by operation of law, assign this Lease or sublease the Premises or any part thereof or mortgage, pledge, or hypothecate its leasehold interest or grant any concession or license within the Premises, and any attempt to do any of the foregoing shall be void and of no effect.

17.2 Permitted Transfers. If Tenant desires to assign, sublease, hypothecate or otherwise transfer this Lease or sublet the Premises other than pursuant to a Permitted (as defined below), then at least 15 Business Days, but not more than 45 Business Days, before date Tenant desires the assignment or sublease to be effective (the “Assignment Date”), Tenant shall give Landlord a notice (the “Assignment Notice”) containing such information about the proposed assignee or sublessee, including the proposed use of the Premises and any Hazardous Materials proposed to be used, stored handled, treated, generated in or released or disposed of the Premises, the Assignment Date, any relationship between Tenant and the proposed assignee sublessee, and all material terms and conditions of the proposed assignment or sublease, a copy of any proposed assignment or sublease in its final form, and such other information as Landlord may deem reasonably necessary or appropriate to its consideration whether to grant its consent. Landlord may, by giving written notice to Tenant within 15 Business Days after receipt of the Assignment Notice: (i) grant such consent, or (ii) refuse such consent, in its reasonable discretion; or (iii) if the proposed assignment, hypothecation or other transfer or subletting concerns (x) an entire floor of the Building or (y) more than (together with all other then subleases) 50% of the Premises with a proposed sublease term that would expire during the last months of the Term, terminate this Lease with respect to the space described in the Assignment Notice as of the Assignment Date (an “Assignment Termination”). Among other reasons, it be reasonable for Landlord to withhold its consent in any of these instances: (1) the proposed assignee or subtenant is a governmental agency; (2) in Landlord’s reasonable judgment, the use the Premises by the proposed assignee or subtenant would entail any Alterations that would

substantially lessen the value of the leasehold improvements in the Premises, or would require substantially increased services by Landlord; (3) in Landlord’s reasonable judgment, the assignee lacks the creditworthiness to support the financial obligations it will incur under the proposed assignment–(4) in Landlord’s reasonable judgment, the business of the proposed or subtenant is inconsistent with the type and quality of the nature of the Building; (5) the use of the Premises by the proposed assignee or subtenant will violate any applicable Legal (6) Landlord has experienced previous defaults by or is in litigation with the proposed assignee subtenant; (7) the proposed assignee or subtenant is an existing tenant in the Building or a prospective tenant with whom Landlord has been in negotiations; or (8) if the assignment or subletting concerns more than 50% of the Premises, the net worth (as determined in accordance with generally accepted accounting principles) of the proposed assignee or subtenant is less than $10,000,000. If Landlord delivers notice of its election to exercise an Assignment Termination, Tenant shall have the right to withdraw such Assignment Notice by written notice to Landlord of such election within 5 Business Days after Landlord’s notice electing to exercise the Assignment Termination. If Tenant withdraws such Assignment Notice, this Lease shall continue in full and effect. If Tenant does not withdraw such Assignment Notice, this Lease, and the term and estate herein granted, shall terminate as of the Assignment Date with respect to the space in such Assignment Notice. No failure of Landlord to exercise any such option to terminate this Lease, or to deliver a timely notice in response to the Assignment Notice, shall be deemed to be Landlord’s consent to the proposed assignment, sublease or other transfer. Tenant shall Landlord for its reasonable, out of pocket costs in connection with its consideration of any Assignment Notice and/or its preparation or review of any consent documents (provided that expenses shall not exceed $5,000 in any one instance with respect to the approval of any assignments or sublets unless such assignment or sublease does not occur in the ordinary course business (e.g. is in connection with a bankruptcy or reorganization of tenant), involves additional documentation beyond Landlord’s customary form of consent or significant negotiation of the same, or Landlord provides unusual or extraordinary services in connection therewith).

Notwithstanding the foregoing, Landlord’s consent to an assignment of this Lease or a subletting of any portion of the Premises to any entity controlling, controlled by or under common control with Tenant (a “Control Permitted Assignment”) shall not be required, provided that Landlord shall have the right to approve the form of any such sublease or assignment. In addition, Tenant shall have the right to assign this Lease, upon prior written notice to Landlord but without obtaining Landlord’s prior written consent, to a corporation or other entity which is a successor-in-interest to Tenant, by way of merger, consolidation or corporate reorganization, or by the purchase of all or substantially all of the assets or the ownership interests of Tenant 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 Lease, and (ii) the net worth (as determined in accordance with generally accepted accounting principles (“GAAP”)) of the assignee is not less than the net worth (as determined in accordance with GAAP) of Tenant as of the date of Tenant’s most current quarterly or annual financial statements, and (iii) such assignee shall agree in writing to assume all of the terms, covenants and conditions of this Lease arising after the effective date of the assignment (a “Corporate Permitted Assignment”). Control Permitted Assignments and Corporate Permitted Assignments are hereinafter referred to as “Permitted Assignments.”

Notwithstanding anything to the contrary in this Article, Tenant shall have the right to obtain financing from investors (including venture capital funding and corporate partners) which invest in private companies or undergo a public offering which results in a change in control of Tenant without such change of control constituting an assignment under this Section requiring Landlord consent, provided that (i) Tenant notifies Landlord in writing of the financing prior to closing of the financing, and (ii) provided that in no event shall such financing result in a change use of the Premises from the use contemplated by Tenant at the commencement of the Term.

17.3 Additional Conditions. As a condition to any such assignment or subletting, whether or not Landlord’s consent is required, Landlord may require:

(i) that any assignee or subtenant agree, in writing at the time of such assignment or subletting, that if Landlord gives such party notice that Tenant is in Default under this Lease, such party shall thereafter make all payments otherwise due Tenant directly to Landlord, which payments will be received by Landlord without any liability except to credit such payment against those due under the Lease, and any such third party shall agree to attorn to Landlord or its successors and assigns should this Lease be terminated for any reason; provided, however, in no event shall Landlord 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 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 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 Landlord has given its written consent to do so, which consent may be withheld in Landlord’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 Tenant nor any such proposed assignee or subtenant is required, however, to provide Landlord 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.

17.4 No Release of Tenant, Sharing of Excess Rents. Notwithstanding any or subletting, Tenant and any guarantor or surety of Tenant’s obligations under this Lease shall at all times remain fully and primarily responsible and liable for the payment of Rent and for compliance with all of Tenant’s other obligations under this Lease. If the Rent due and payable a sublessee or assignee (or a combination of the rental payable under such sublease or plus any bonus or other consideration therefor or incident thereto in any form) exceeds the sum the rental payable under this Lease, (excluding however, any Rent payable under this Section) actual and reasonable brokerage fees, legal costs and any design or construction fees directly related to and required pursuant to the terms of any such sublease and any tenant improvement expenses paid by Tenant in excess of Landlord’s Contribution) (“Excess Rent”), then Tenant be bound and obligated to pay Landlord as Additional Rent hereunder 50% of such Excess Rent within 10 days following receipt thereof by Tenant. If Tenant shall sublet the Premises or any

thereof, Tenant hereby immediately and irrevocably assigns to Landlord, as security for Tenant’s obligations under this Lease, all rent from any such subletting, and Landlord as assignee and as attorney-in-fact for Tenant, or a receiver for Tenant appointed on Landlord’s application, may collect such rent and apply it toward Tenant’s obligations under this Lease; except that, until the occurrence of a Default, Tenant shall have the right to collect and retain such rent.

17.5 No Waiver. The consent by Landlord to an assignment or subletting shall not relieve Tenant or any assignees of this Lease or any sublessees of the Premises from obtaining consent of Landlord to any further assignment or subletting nor shall it release Tenant or any assignee or sublessee of Tenant from full and primary liability under the Lease. The acceptance 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 of this Lease or a consent to any subletting, assignment or other transfer of the Premises.

17.6 Prior Conduct of Proposed Transferee. Notwithstanding any other provision of this Section, if the proposed assignee or sublessee has operations in the Commonwealth of Massachusetts that are or have been subject to an enforcement order issued by any Governmental Authority and such operations are substantially comparable to the operations proposed by the assignee or sublessee for the Premises 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) pertaining to a use similar to the Permitted Use, Landlord shall have the absolute right to refuse to consent to assignment or subletting to any such party.

ARTICLE 18

ESTOPPEL CERTIFICATE

18.1 Estoppel Certificate. Tenant shall, within 10 Business Days of written notice Landlord, execute, acknowledge and deliver a statement to Landlord, or any prospective or lender, in writing (i) certifying that this Lease is unmodified and in full force and effect (or, if modified, stating the nature of such modification and certifying that this Lease as so modified is full force and effect) and the dates to which the rental and other charges are paid in advance, if (ii) acknowledging that there are not any uncured defaults on the part of Landlord hereunder, or specifying such defaults if any are claimed, and (iii) setting forth such further information with respect to the status of this Lease or the Premises as may be requested thereon. Any such may be relied upon by any prospective purchaser or encumbrancer of all or any portion of the property of which the Premises are a part. Tenant’s failure to deliver such statement within such time shall, at the option of Landlord, constitute a Default under this Lease, and, in any event, be conclusive upon Tenant that the Lease is in full force and effect and without modification except as may be represented by Landlord in any certificate prepared by Landlord and delivered Tenant for execution. Landlord shall, within 10 Business Days of written notice from Tenant, execute, acknowledge and deliver a comparable statement to Tenant.

ARTICLE 19

SUBORDINATION

19.1 Subordination. This Lease and Tenant’s interest and rights hereunder are hereby made and shall be subject and subordinate at all times to the lien of any Mortgage now existing hereafter created on or against the Project or the Premises, and all amendments, restatements, renewals, modifications, consolidations, refinancing, assignments and extensions thereof, provided that the Holder of such Mortgage delivers to Tenant a subordination, non-disturbance and attornment agreement on such holder’s standard and customary form provided that such holder is an institutional lender or investor. Tenant agrees, at the election of the Holder of any Mortgage, to attorn to any such Holder. Notwithstanding the foregoing, any such Holder may at any time subordinate its Mortgage to this Lease, without Tenant’s consent, by notice in writing Tenant, and thereupon this Lease shall be deemed prior to such Mortgage without regard to their respective dates of execution, delivery or recording and in that event such Holder shall have the same rights with respect to this Lease as though this Lease had been executed prior to the execution, delivery and recording of such Mortgage and had been assigned to such Holder. The term “Mortgage” whenever used in this Lease shall be deemed to include deeds of trust, security assignments and any other encumbrances, and any reference to the “Holder” of a Mortgage shall be deemed to include the beneficiary under a deed of trust.

19.2 Ground Lease. Landlord represents and warrants that Landlord has enforceable leasehold rights in the land comprising the Project by virtue of the Ground Lease dated November 12, 2010, by and between Bent Associates Limited Partnership, as landlord (“Ground Lessor”), and Landlord as tenant (“Ground Lease”). Landlord represents and warrants that the Ground Lease is in full force and effect and, to its knowledge, there are no defaults under the Ground Lease as of the date hereof. Landlord shall cause the Ground Lessor to enter into a subordination and non-disturbance agreement substantially in the form attached hereto as Exhibit K for Tenant’s benefit.

ARTICLE 20

SURRENDER

20.1 Surrender. Upon the expiration of the Term or earlier termination of Tenant’s of possession, Tenant shall surrender the Premises to Landlord in the condition the Premises are required to be maintained during the Term, along with any Alterations or Installations permitted Landlord to remain in the Premises pursuant to the provisions of this Lease, free of Hazardous Materials brought upon, kept, used, stored, handled, treated, generated in, or released or disposed of from, the Premises by Tenant or any Tenant Party or subtenant (collectively, “Tenant Operations”) and released of all Hazardous Materials Clearances, broom clean, ordinary wear tear and casualty loss and condemnation covered by Sections 14 and 15 excepted. At least 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 Installations permitted by Landlord to remain in the Premises) at the expiration or earlier termination of the Term, free from any impact from the Tenant HazMat Operations and otherwise released for unrestricted use and occupancy (the “Surrender Plan”). Such Surrender Plan shall be accompanied by a current listing of (i) all Hazardous Materials licenses and permits held by or on behalf of any Tenant

with respect to the Premises, and (ii) all Hazardous Materials used, stored, handled, treated, generated, released or disposed of from the Premises, and shall be subject to the review and approval of Landlord’s environmental consultant. In connection with the review and approval of the Surrender Plan, upon the request of Landlord, Tenant shall deliver to Landlord or its such additional non-proprietary information concerning Tenant HazMat Operations as Landlord shall request. 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 HazMat Operations.

If Landlord determines that this representation and warranty was not true as of the date of this lease, Landlord shall have the right to terminate this Lease in Landlord’s sole and absolute discretion.

such non-proprietary information concerning the use of Hazardous Materials in or about the Premises by Tenant or any Tenant Party. If contamination has occurred for which Tenant is under this Section, Tenant shall pay all costs to conduct such tests. If no such contamination is found, Landlord shall pay the costs of such tests (which shall not constitute an Operating Landlord shall provide Tenant with a copy of all third party, non-confidential reports and tests of the Premises made by or on behalf of Landlord during the Term without representation or and subject to a confidentiality agreement. Tenant shall, at its sole cost and expense, promptly satisfactorily remediate any environmental conditions identified by such testing for which Tenant is responsible hereunder in accordance with all Environmental Requirements. Landlord’s receipt of or satisfaction with any environmental assessment in no way waives any rights which may have against Tenant.

21.5 Control Areas. Tenant shall be allowed to utilize up to its pro rata share of the Hazardous Materials inventory within any control area or zone (located within the Premises), as designated by the applicable building code, for chemical use or storage. As used in the sentence, Tenant’s pro rata share of any control areas or zones located within the Premises shall determined based on the rentable square footage that Tenant leases within the applicable control area or zone. For purposes of example only, if a control area or zone contains 10,000 rentable square feet and 2,000 rentable square feet of a tenant’s premises are located within such control area or zone (while such premises as a whole contains 5,000 rentable square feet), the applicable tenant’s pro rata share of such control area would be 20%.

If both parties submit Extension Proposals, then Landlord and Tenant 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 Market Rate. If Landlord and Tenant 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 for the Extension Term. The two Arbitrators so appointed shall, within five (5) Business Days after their appointment, appoint a third Arbitrator. If the two 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 Premises are located, upon ten (10) days prior written notice to the other party of such intent.

(a) 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. The decision of the single Arbitrator shall be final and binding upon the parties. The average of the two closest Arbitrators in a three Arbitrator panel 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 the Market Rate is not determined by the first day of the Extension Term, then Tenant shall pay Landlord Base Rent in an amount equal to the Base Rent in effect immediately prior to the Extension Term until such determination is made. After the determination of the Market Rate, the parties shall make any necessary adjustments to such payments made by Tenant. Landlord and Tenant shall then execute an amendment recognizing the Market Rate for the Extension Term.

(b) 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 ten (10) years of experience in the appraisal of improved office and high tech industrial real estate in the greater Boston, Massachusetts metropolitan area, or (B) a licensed commercial real estate broker with not less than fifteen (15) years experience representing landlords and/or tenants in the leasing of high tech or life sciences space in the greater Boston, Massachusetts metropolitan area, (ii) devoting substantially all of their time to professional appraisal or brokerage work, as applicable, at the time of appointment and (iii) be in all respects impartial and disinterested.

28.3 Rights Personal. The Extension Right is personal to Tenant and any transferee pursuant to a Permitted Assignment and is not otherwise assignable without Landlord’s consent, which may be granted or withheld in Landlord’s sole discretion separate and apart from any consent by Landlord to an assignment of Tenant’s interest in the Lease.

28.4 Exceptions. Notwithstanding anything set forth above to the contrary, at Landlord’s option, the Extension Right shall not be in effect and Tenant may not exercise the Extension Right:

(i) during any period of time that Tenant is in Default under any provision of this Lease; or

(ii) if Tenant has been in Default under any provision of this Lease three or more times, whether or not the Defaults are cured, during the 12 month period immediately prior to the date that Tenant intends to exercise the Extension Right, whether or not the Defaults are cured.

28.5 No Extensions. The period of time within which the Extension Right may be exercised shall not be extended or enlarged by reason of Tenant’s inability to exercise the Right.

28.6 Termination. The Extension Right shall, at Landlord’s option, terminate and be of no further force or effect even after Tenant’s due and timely exercise of the Extension Right, if, after such exercise, but prior to the commencement date of the Extension Term, (i) Tenant fails to timely cure any Default by Tenant under this Lease; or (ii) Tenant has Defaulted three or more times during the period from the date of the exercise of the Extension Right to the date of the commencement of the Extension Term, whether or not such Defaults are cured.

Part A: Introduction and General Information

Why Green?

Buildings in the United States consume over 80% of the total electricity and more than 30% of total energy used annually. Buildings also utilize significant amounts of fresh water during both construction and occupancy. Material waste during construction accounts for up to 53% of landfill waste, depending on location. A well designed, sustainable building works to reduce impact on the environment while garnering financial and health-related benefits for the Owner and Tenants.

Currently, people spend over 90% of their time in buildings- much of that time at work. One benefit of a green building for occupants is the more comfortable and controllable environment designed into sustainable buildings. The impact of such an attribute can be manifested in increased employee retention and productivity.

United States Green Building Council and LEED

The United States Green Building Council (USGBC) is a nonprofit organization committed to expanding sustainability in the built environment. Its mission is to transform the way buildings and communities are designed, built and operated, enabling an environmentally and socially responsible, healthy, and prosperous environment that improves the quality of life. LEED (Leadership in Energy and Environmental Design) is a voluntary, consensus-based national rating system for developing high-performance, sustainable buildings.

Developed by the USGBC, LEED addresses all building types and emphasizes state-of-the-art strategies for sustainable site development, water savings, energy efficiency, materials and resource selection, and indoor environmental quality. LEED is a voluntary rating system for green building design and construction that provides immediate and measurable results for building owners and occupants.

Opportunities for Tenants

Tenants at 150 Second have a remarkable opportunity to help lead the shift to sustainability in buildings, and in the process define a new kind of workplace. By locating in a LEED Gold building, tenants will benefit from a high performance building with excellent indoor air quality and ample daylight and views. These and other elements combine to create a healthier workplace and improve the indoor environment for all

employees. In addition, 150 Second has set a higher standard with high-performance technologies that use less energy, consume less water, and leave a smaller footprint on the city’s resources. Some of the building’s innovative features will be noticed at once: low flow plumbing fixtures and the zero irrigation rain garden. Others, such as energy-saving base building mechanical systems will exist behind the scenes, quietly but significantly setting the building apart from its neighbors.

The LEED Guidelines that follow summarize the measures that Skanska has taken to achieve LEED Gold certification for 150 Second. These guidelines are intended to help tenants understand and take full advantage of the high-performance features of the building, and to provide guidance in ways that tenants can reinforce these features in their own workplaces.

Skanska set a goal of achieving LEED Gold for the base building at 150 Second using LEED for Core and Shell (LEED-CS) version 2009. We can only design and build the building, however. It is up to our tenants to fit it out and operate it in an environmentally friendly way. To do this, we recommend you use the LEED for Commercial Interiors (LEED-CI) rating system. The intent of LEED-CI is to assist in the creation of high-performance, healthy, durable, affordable and environmentally sound commercial interiors. Together LEED-CS and LEED-CI address the commercial office real estate market for both developers and tenants enabling significant benefits through improved indoor air quality, maximized day lighting and lower energy costs. A copy of the LEED-Cl 2009 Scorecard and link to the Rating System are included in Appendix A for reference by tenants who wish to explore more information on timing and detailed strategies.
