NOW THEREFORE, for One ($1.00) Dollar and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows:

1.	Original Term Expiration and Commencement of the Extended Lease Term

The current Term under the Original Lease, prior to this Amended and Restated Lease Agreement, expires on June 30, 2007. Effective as of the Substitution Date, LESSEE shall vacate and surrender the Current Leased Premises to LESSOR and LESSOR shall accept such surrender from LESSEE and the Original Lease shall be deemed terminated provided that Subtenant shall have access to the Current Leased Premises for a period of up to thirty (30) days after the Substitution Date in order to satisfy the provisions of the Original Lease pertaining to the condition in which the Current Leased Premises are to be delivered to LESSOR (e.g. Lease Sections 26 and 28), and to effectuate the transfer of LESSEE’S equipment and furniture from the Current Leased Premises to the Substituted Leased Premises in a timely and orderly manner.

As of the Substitution Date, the Term of the Original Lease (as amended by this Amended and Restated Lease Agreement) will be extended for a period beginning on the Substitution Date and expiring on May 31, 2010 (the “Extended Term”); and LESSEE shall lease the Substituted Leased Premises under the Rent, terms and conditions as set forth in this Amended and Restated Lease Agreement up to the expiration of said Extended Term.

To the extent LESSOR cannot deliver the Substituted Leased Premises to LESSEE on or prior to June 30, 2007, the term of the Original Lease shall be automatically extended through that date which subsequently becomes the Substitution Date, except that the Rent thereunder shall be amended to be equal to the Rent for the Substituted Leased Premises during the first Lease Year of the Extended Term.

The term “Lease Year” as used herein and for all purposes during the Extended Term shall mean the period beginning on the Substitution Date and ending on the day immediately prior to each anniversary of the Substitution Date, provided that the Third Lease Year shall end on May 31, 2010.

2.	The Substituted Leased Premises

LESSOR and LESSEE hereby agree that during the Extended Term, the Substituted Leased Premises, as defined herein and as depicted on Exhibit A attached hereto, shall be deemed to mean the “Leased Premises” as referred to in the Lease, unless the context specifically means the “Current Leased Premises.”

The Substituted Leased Premises may be used by LESSEE for general office, research and laboratory uses only, as set forth in Section 6 of the Lease, throughout the Extended Term.

Provided the same does not materially interfere with LESSOR’S obligations under Section 5 hereof (in which case LESSEE’S rights under this paragraph shall be expressly subordinate in LESSOR’S sole discretion). LESSEE shall have reasonable supervised access to the Substituted Leased Premises commencing on the date of this Agreement to install trade fixtures and/or cabling and/or communications equipment, and to reconfigure and move laboratory and office equipment. Such early access by LESSEE shall be subject to such times and in such manner as LESSOR may reasonably determine to avoid material interference with LESSOR’S Work.

LESSEE shall not be charged any fees by LESSOR for use of the freight elevators of the building, supervision or otherwise in connection with LESSEE’S move from the Current Leased Premises to the Substituted Leased Premises.

LESSOR shall provide the services of LESSOR’S internal space planning and design staff, at LESSOR’S cost and expense, on a reasonable basis to assist LESSEE in its own space planning and design.

Except as otherwise set forth in Section I on account of the Substitution Date occurring after June 30, 2007, LESSEE shall continue to pay Annual Base Rent under the Original Lease for the Current Leased Premises up to the Substitution Date.

4.	Additional Rent

Notwithstanding the provisions of the Original Lease, this Amended and Restated Lease Agreement is structured as a “triple net” lease. Accordingly, the provisions for Additional Rent based on Operating Expenses and Taxes are rewritten as follows.

LESSEE shall also pay to LESSOR, as Additional Rent under the Lease, the following amounts based on LESSEE’S allocable percentage (which is 8.3441%, the ‘‘Allocable Percentage”):

A. Operating Expenses: LESSEE shall be responsible for payment of Additional Rent attributable to the Operating Expenses for the Building and site, based on LESSEE’S Allocable Percentage. Operating Expenses, as set forth in Exhibit B hereto, are the unaudited actuals for calendar year 2006 (and will be subject to change based on actual costs and expenses incurred for each of the categorized Exhibit B costs and expenses in 2007 and each subsequent year during the Extended Term). “Operating Expenses” shall not include the following: the costs of LESSEE’S improvements and services for which LESSEE or any tenant specifically and directly reimburses LESSOR, or pays third persons at LESSOR’S directions; income or franchise taxes of the LESSOR; the costs incurred in any rehabilitation, reconstruction or other work occasioned by any insured casualty (i.e. as to which LESSOR is required to carry insurance hereunder), or by the exercise of the right of eminent domain (except to the extent of any so-called “deductible” amount under policies of insurance or any costs actually incurred for which any insurance company does not reimburse or compensate LESSOR or Owner); depreciation of the Building; general corporate overhead of the LESSOR entity; legal expenses incurred in any direct dispute with any particular tenant (other than those incurred which are of benefit to or protect the rights of other tenants in the Building, generally); costs of renovations to other tenants’ spaces; costs of capital improvements; brokerage and advertising costs in seeking new tenants; and penalties incurred due to LESSOR’S willful violation of any direct violation of any government order.

B. Tax Expenses: LESSEE shall be responsible for payment of Additional Rent attributable to the municipal real estate taxes on the Building and land on which it is situated, based on LESSEE’S Allocable Percentage.

Additional Rent for Operating Expenses and Tax Expenses shall be payable as invoiced by LESSOR (accompanied by a copy of the applicable municipal tax ▇▇▇▇), and failure to make any such payments within thirty (30) days of such invoice shall be a default under this Amended and Restated Lease Agreement.

C. Utilities: Landlord shall provide and Tenant shall pay utilities attributable to the Substituted Leased Premises as set forth in Section 7 of the Original Lease.

5.	Condition of the Current Leased Premises on the Substitution Date; and Landlord’s Work on the Substituted Leased Premises

The Current Leased Premises shall be vacated and surrendered by the LESSEE in accordance with the provisions of Sections 26 and 28 of the Lease, upon delivery of the Substituted Leased Premises to the LESSEE by the LESSOR as contemplated herein.

LESSOR and LESSEE acknowledge that LESSOR shall deliver and LESSEE shall accept delivery of the Substituted Leased Premises as of the beginning of the Extended Term in an AS/IS condition in all respects, but for: (a) the specific work to be performed by LESSOR as set forth in Exhibit C hereto (the “LESSOR’S Work”); (b) in vacant and clean condition; (c) with the laboratory areas “decommissioned” (i.e. free of any environmental hazards or materials such that it is not in violation of applicable environmental laws consistent with the same standards set forth in Section 26 of the Lease) and sanitized. Landlord represents that the Substituted Leased Premises currently has the benefit of a certificate of occupancy from the City of Cambridge therefor which permits the use of the Substituted Leased Premises for the uses permitted under this Lease, and to the extent any additional building permit (or resulting certificate of occupancy is required on account of LESSOR’S Work), then LESSOR shall be required to procure and deliver the same to LESSEE. LESSOR’S Work shall be performed at LESSOR’S sole cost and expense, and shall be substantially completed as of the beginning of the Extended Term. LESSOR shall perform LESSOR’S Work in a good and workmanlike manner and in compliance with all applicable laws and governmental regulations. LESSEE shall inspect such work upon delivery by LESSOR, and hereby acknowledges there are no special installations or other requirements with respect thereto which do not appear on Exhibit C hereto. Notwithstanding LESSOR’S obligation to perform LESSOR’S Work, LESSOR shall not be liable for any damages resulting from LESSEE’S transfer of its operations and equipment from the Current Leased Premises to the Substituted Leased Premises or performance of any of its business functions (e.g. laboratory work) from the newly installed facilities in the Substituted Leased Premises; LESSEE assuming all such risk and waiving any and all claims against LESSOR with respect thereto. If LESSOR is unable to fulfill the conditions set forth above within one hundred twenty (120) days after June 15, 2007, then LESSEE, as its sole and exclusive remedy at law or in equity shall be entitled to terminate this Amended and Restated Lease Agreement by written notice to LESSOR delivered within ten (10) days of the expiration of said one hundred twenty (120) day period, and this Amended and Restated Lease Agreement shall be null and void and without recourse to either party, but LESSEE shall be entitled to remain in occupancy of the Current Leased Premises at the rent set forth in this Amended and Restated Lease Agreement for ninety (90) days after such termination.

LESSOR shall be solely responsible for any costs associated with the architectural and engineering work and permits required for LESSOR’S Work; and LESSOR shall provide such architectural and engineering and permitting services as part of LESSOR’S Work.

6.	Security/Guaranty

The LESSEE’S obligations to post and maintain a Security Deposit under Section 5 of the original Lease shall also be required during the Extended Term.

Parking

The provisions of Section 16 of the Lease shall continue to govern LESSEE’S parking rights and LESSEE shall be entitled to the same number of spaces set forth therein. LESSEE acknowledges that the current rate for such parking spaces is $ 210.00 per space per month. However, notwithstanding the provisions of Section 16 of the Lease, LESSOR shall determine from time to time in its discretion the extent to which spaces are provided in the LESSOR’S Building or at ▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇ (provided all the spaces contemplated in said Section 16 are provided from one location or the other, with a minimum of fifteen (15) to be provided at ▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇).

8.	Brokers Commissions/Indemnification

LESSOR has retained ▇▇▇▇▇▇▇▇ & Grew, and LESSEE has had some dealings with said brokerage firm, relative to the Building. The LESSOR and LESSEE each represent to the other that they have not dealt, directly or indirectly, with any other broker, or other entity or individual entitled to any commission relative to the Substituted Leased Premises leased to LESSEE for the Extended Term hereunder. Each party agrees to indemnify and hold harmless the other from and against any claims for commission arising out the execution and delivery of this agreement and any renewals, extensions or expansions hereof other than the foregoing; LESSOR expressly agreeing that it shall be responsible for any claims made by ▇▇▇▇▇▇▇▇ & Grew relative to this transaction, based on separate agreement between LESSOR and ▇▇▇▇▇▇▇▇ & Grew.

9.	Assignment/Subletting

The LESSEE shall have the right to assign the Lease and/or sublet the Leased Premises (in whole or in part) subject to all the terms and conditions of Section 12 of the Original Lease.

10.	Integration of Documents; Supremacy

Notwithstanding the commencement of the Extended Term on the Extension Commencement Date hereunder, this Lease Extension is to be considered a valid and binding obligation of the parties effective as of the date of execution of this Second Lease Extension Agreement by the parties and its approval by Lessor’s lender (which approval is an express condition to the extension and expansion contemplated herein and which Lessor shall seek immediately upon execution of this Agreement by both parties); with the Existing Lease to continue to govern the Lessee’s use and occupancy of the Existing Premises hereunder through the Term and up to the Extension Commencement Date hereunder, subject to the supplemental provisions hereof relating to the Expansion Space (defined herein). Lessee agrees to execute the Landlord’s lender’s standard Subordination Non-Disturbance and Attornment Agreement upon execution of this Second Lease Extension Agreement and Lessor agrees to promptly use commercially reasonable efforts to seek its lender’s execution of the same, but without any obligation to actually deliver the same to Lessee and without any material impact on this Second Lease Extension Agreement or the underlying Existing Lease upon any failure to do so.

2.	Terms and Conditions

Lessee shall lease the Total Leased Premises (with the addition of the Expansion Space to be leased as of the Expansion Space Delivery Date) on the same terms and conditions of the Existing Lease, as modified by this Second Lease Extension Agreement, with exception only for

those provisions as to which Lessor and Lessee have already performed their obligations as of the date hereof, (for example, Lessor has heretofore delivered the Existing Premises and Lessee has accepted the same). The Existing Premises is leased in the same “AS/IS’1 condition as it is as of the execution of this Second Lease Extension Agreement, and Lessee acknowledges Lessor is under no obligation to make any improvements or modifications thereto, in any manner.

3.	Expansion Space Added to the Existing Premises

Lessor shall deliver the Expansion Space to Lessee (to be added to and, in the aggregate, to constitute the Total Leased Premises). The Expansion Space shall be delivered to the Lessee upon Substantial Completion (as defined below) of Lessor’s Work (as defined herein below) on the office portion of the Expansion Space (the “Office Expansion Space”) and on the laboratory portion of the Expansion Space (the “Lab Expansion Space”), herein, the “Office Expansion Delivery Date” and the “Lab Expansion Delivery Date” respectively, and also referred to herein collectively as the “Expansion Delivery Dates”. As of the respective Expansion Delivery Dates, the Office Expansion Space and the Lab Expansion Space, respectively, shall be Substantially Complete, vacated by any current tenants and occupants; with Lessor’s Work having been performed in a good and workmanlike manner according to Lessor’s Scope of Work; broom clean.

All terms and conditions of the Lease shall govern the Lessee’s use and occupancy of the Expansion Space as of the respective Expansion Space Delivery Dates.

Lessor’s delivery of the Office Expansion Space and the Lab Expansion Space shall be evidenced in each instance by a written notice of delivery (“Lessor’s Delivery Notice”) given to Lessee on the actual date the respective portion of the Expansion Space is Substantially Complete and provided to Lessee for its occupancy. Lessee shall have five (5) business days to contest delivery if the Expansion Space is not Substantially Complete or it does not conform with the Lessor’s Scope of Work and Lessor’s Work by delivering its notice thereof in writing to Lessor; however, any listed items of a “punchlist” nature shall be agreed to by Lessor and Lessee and shall not be grounds to contest delivery, but nevertheless shall obligate Lessor to complete such punchlist items at the earliest practicable time under the circumstances.

The following conditions to the delivery of the Office Expansion Space and the Lab Expansion Space to the Lessee by the Lessor shall be met by the Lessor, at its sole cost and expense, prior to the respective Expansion Delivery Dates. The Lessor shall perform, at its sole cost and expense, such design and construction work as is necessary to deliver the respective portions of the Expansion Space to the Lessee in accord with the “Scope of Landlord’s Work for Additional Premises Only” dated August 13, 2012 attached hereto as Exhibit A (the Exhibit referred to as the “Lessor’s Scope of Work” and the design and construction obligations thereunder being referred to as the “Lessor’s Work”). All components of Lessor’s Work will be completed in accordance with all applicable laws, rules and regulations, including but not limited to the latest requirements of NFPA, ANSI Standards, ASHRAE Standards, National Electrical Code, Massachusetts State Building Code, and regulations of the City of Cambridge. Lessor shall deliver the Expansion Space with the base Building systems serving the same and with Lessee’s specific mechanical, electrical and plumbing systems as required in Lessor’s Scope of Work (i.e. Exhibit A hereto), in good operating condition and repair, and suitable for their intended uses.

All utilities for the Expansion Space shall be in place and separately metered. The Building and the Expansion Space as delivered to the Lessee will be compliant with the Americans with Disabilities Act; NFPA compliant pursuant to the Massachusetts State Building Code; and with code compliant demising walls and common area corridors. Lessor shall provide Lessee with the environmental close-out report prepared by the former tenant for the Expansion Space, and said report shall not disclose any conditions as would materially impair Lessee’s use of the Expansion Space. Subject to the foregoing, Lessor shall not be responsible for any other design or construction work with respect to either the Existing Premises under the Existing Lease, or the Expansion Space.

To the extent Lessee seeks to make any changes to the Lessor’s Scope of Work as set forth on Exhibit A hereto: (i) such changes will be communicated in writing with sufficient specificity for Lessor to price the changes; (ii) Lessor will provide Lessee with pricing as to such changes and any estimated delays, if any, that may result for such changes; and (iii) in the event such changes affect the total cost of the Lessor’s Scope of Work, Lessee shall either reimburse Lessor in advance for any increased costs and expenses, or Lessor shall credit Lessee for any savings against Lessee’s next due payments of Rent hereunder. Upon receiving from Lessor the estimated cost and timing impacts of Lessee’s proposed changes pursuant to subsection (ii) above, Lessee may choose to not move forward with such proposed changes provided it communicates its final intention to the Lessor in writing within ten (10) days of its receipt of Lessor’s cost and timing impacts. Lessee shall be solely responsible for any delays in the completion of Lessor’s Work arising from any such requested changes.

The Lessee shall be solely responsible, at its sole cost and expense, to perform such other specific design and construction work on the Expansion Space as it desires for its use and occupancy (“Lessee’s Work”), upon completion of the Lessor’s Work in the respective office and laboratory portions of the Expansion Space, and delivery of those respective portions the Expansion Space by the Lessor. Lessee shall be provided with access to the Expansion Space commencing upon execution of this Second Lease Extension Agreement, coordinated through the Lessor, for the purpose of performing preliminary work toward the installation of its equipment and wiring, provided such access and preliminary work does not materially interfere with Lessor’s ability to perform and complete its Lessor’s Work, which shall take precedence in all respects. Lessee’s Work and all subsequent Lessee alterations to the Leased Premises that are performed by Lessee on or affecting the fire, life safety and/or sprinkler systems of the building shall be made in such a manner and under such conditions as to pose no adverse impact or interruption to such fire, life safety, and sprinkler systems, and so as not to delay, impair, or jeopardize the legal occupancy of other tenants in the Building as determined by Lessor and municipal fire and building inspection officials.

The Lessor’s Work as to the Office Expansion Space and the Lab Expansion Space, separately, will be deemed “Substantially Complete” as to each: (a) when Lessor’s Work is substantially complete in accordance with Lessor’s Scope of Work as set forth in Exhibit A and the provisions of this Section 3, except for minor punch list items approved by Lessee that will not materially adversely affect Tenant’s normal operations in said Expansion Space; Lessor’s Work therein having been performed in a good and workmanlike manner with all necessary municipal approvals for occupancy.

4.	Annual Base Rent and Additional Rent

Annual Base Rent from the date of execution of this Second Lease Extension Agreement through the Extended Term, shall be as set forth below:

A.	Annual Base Rent as applied to the Existing Premises

(i.e. 9,538 rentable square feet of space)

(i)

Balance of the Current Term As set forth in the Existing Lease

(ii)

Extension Commencement Date $ 145,136.57 ($ 36,284.14 / mo.)

through the Termination Date

B.	Annual Base Rent as applied to the Expansion Space (i.e. 8,110 rentable square feet of space)

(i)

Expansion Space Staggered Delivery Periods—Interim Rent/Per ▇▇▇▇

▇▇▇▇▇▇’▇ estimated delivery of the Office Expansion Space is targeted to October 1, 2012. Lessor’s estimated delivery of the Lab Expansion Space is targeted to December 1, 2012. The first day of the calendar month following the day on which the Office Expansion Delivery Date occurs is referred to herein as the “Expansion Rent Start Date”). A per diem calculation is required to determine interim Rent obligations occurring upon delivery of the respective Office Expansion Space and Lab Expansion Space. Annual Base Rent for the total Expansion Space (office and laboratory) for the first full twelve month period following the Expansion Rent Start Date is $395,362.50 ($32,946.88 on a monthly basis). This computes to $1,083.18 on a per diem basis. The per diem amount allocated to the Office Expansion Space is $496.42, (i.e. 45.83% at 3,717 rentable square feet of a total 8,110 rentable square feet), the “Office Per Diem”. The per diem amount allocated to the Lab Expansion Space is $586.76 (i.e. 54.17% at 4,393 rentable square feet of a total 8,110 rentable square feet), the “Lab Per Diem”.

(x) For the interim period between the Office Expansion Delivery Date and the Expansion Rent Start Date, the Annual Base Rent payment attributable to the Office Expansion Space shall be determined by taking the number of days from the Office Expansion Delivery Date through the Expansion Rent Start Date and multiplying by $496.42. This amount shall be paid to Lessor.

(y) For the interim period between the Lab Expansion Delivery Date and the Expansion Rent Start Date (given the possibility the Expansion Rent Start Date may not have occurred due to delays in delivery of the Office Expansion Space),the Annual Base Rent payment attributable to the Lab Expansion Space shall be determined by taking the number of days from the Lab Expansion Delivery Date through the Expansion Rent Start Date (if applicable) and multiplying by $586.76. This amount (if applicable) shall be paid to Lessor.

(ii)

Annual Base Rent due from the Expansion Rent Start Date through the next twelve (12) consecutive months is:

$ 395,362.50 ($ 32,946.88 /mo.)*

*[less the Lab Per Diem for each day in such period that the Lab Expansion Space is not delivered]

(iii)

Annual Base Rent due through the next twelve (12) consecutive months (after (ii) above) is:

$ 405,500.00 ($ 33,791.60/mo.)

(iv)

Annual Base Rent due through the next consecutive months (after (iii) above) to the end of the Extended Term is:

$ variable ($ 34,636.46 / mo.)

In all instances under A and B above, Annual Base Rent shall be payable in the corresponding monthly installments set forth above, due on the first of each month, in advance, and in all other respects shall be subject to the provisions relating to Annual Base Rent as set forth under the Existing Lease.

C.	Additional Rent.

In addition to Annual Base Rent, Lessee shall continue to be responsible to pay all Additional Rent (Operating Expenses) under Section 3 of the Existing Lease, and all Additional Rent (Taxes) under Section 4 thereof, as applicable to both the Existing Premises and the Expansion Space, as invoiced by Lessor during the Extended Term. A current statement outlining the Operating Expenses incurred for the Building in 2011 is attached hereto as Exhibit B.

As the concept is used in the Lease to compute Additional Rent, Lessee’s allocable pro rata share (“Allocable Percentage”) shall be as follows:

(A)	Allocable Percentage for the Existing Premises running through the end of the Term, shall be 7.4 %.

(B)	Allocable Percentage for the Expansion Space, starting on the Expansion Space Delivery Dates and running through the end of the Term, shall be 6.29 %.

To the extent that the Expansion Space Commencement Dates do not fall on the first calendar day of a month, then the first month in which the Expansion Space Commencement Dates occur will have Additional Rent attributable to the Expansion Space prorated on a per diem basis for that month.

D.	Rent and other Costs and Expenses.

All Annual Base Rent, Additional Rent and other sums due as Rent shall be payable and in all other respects shall be governed during the remainder of the Current Term, and for the Extended Term, as contemplated under the Existing Lease, except to the extent modified and supplemented above. All other costs and expenses for utilities and services and attendant to operation of the Total Leased Premises (i.e. as applicable to both the Existing Premises, and to the Expansion Space as of the respective Expansion Space Delivery Dates), shall be borne by the respective parties as set forth in the Existing Lease.

E.	Security Deposit.

The Security Deposit currently held by the Lessor shall continue to be held by Lessor during the Extended Term.

5.	Permitted Uses

The Permitted Uses for the Total Leases Premises shall be office, R&D and laboratory use in conformity with all federal, state, municipal and local laws, codes, ordinances, rules and regulations of governmental authorities, committees, associations, or other regulatory committees, agencies or governing bodies having jurisdiction over the Total Leased Premises, and in conformity with the conditions and restrictions set forth in the Original Lease (which are hereby restated and affirmed by Lessee).

6.	Existing Premises in “AS/IS” Condition—No Defaults

Lessee hereby acknowledges it is currently in possession of the Existing Premises and accordingly accepts the same from the date of this Second Lease Extension Agreement in its current “AS/IS” condition, without representation or warranty of any kind or nature arising from the extension of the Lease by Lessor and Lessee.

Lessor and Lessee each acknowledge that to the best of each of their respective knowledge, there are no material defaults by either presently existing under the Lease.

Brokers

Parking.

Lessee shall be granted, at current rates (which may be increased from time to time to reflect market increases), the right (but not the obligation) to park up to twenty seven (27) cars in total in the Building’s on-site indoor parking lot or facility on an unassigned and unreserved basis, in single or tandem spaces or on a valet basis which Lessor in its sole discretion shall designate from time to time. The initial parking rate therefor shall be S225 per month, per car, which monthly rate may be changed by Lessor in its discretion subject to and reflective of periodic

market changes. Additionally, Lessee shall be entitled to rights to park additional cars in the Building garage (but subject to availability as determined by Lessor, and only on a valet basis, and then only to the extent Lessor is providing valet service to the Building garage which Lessor shall not be obligated to do), at then current rates as set by Lessor in its discretion. If Lessor cannot accommodate Lessee’s needs for additional parking in the Building garage, then Lessor will assist Lessee in identifying alternative off-site parking, but Lessor shall bear no liability nor shall it be deemed any default under the Lease if such additional Building garage parking or off-site parking do not materialize. All payments for these parking rights shall be considered to be Additional Rent under this Lease. This provision supersedes any contrary provisions of the Existing Lease and the specific numeric rights set forth above supplant the numeric rights otherwise set forth in the Existing Lease.

9.	Lessee’s Option to Extend

Provided Lessee has not defaulted (after applicable notice, grace and cure periods, if any) under the Lease from the date hereof forward more than two (2) times, and further provided no uncured default on the part of Lessee is then existing, Lessee shall have the option to further extend the Term of this Lease as to the Total Leased Premises (i.e. inclusive of the Expansion Space) on the terms and conditions herein, for one additional period of thirty six (36) months (herein, the “Additional Term Extension Period”) at the then current “Market Rent” (including annual escalations thereon for each year of the extended term based on increases in the Consumer Price Index or fixed increases, as the case may be, as determined by then prevailing market forces), but no less than an amount equal to the annualized Rent per rentable square foot of Total Leased Premises space as of the final full month of the last Lease Year hereunder (the “Extension Rent Floor”). Said Additional Term Extension Period shall commence, subject to proper exercise of Lessee’s option hereunder, at the end of the Extended Term (i.e. at the end of March, 2015) and shall terminate on that date which is thirty six (36) consecutive months thereafter (i.e. March 31, 2018). Lessee shall exercise its option by delivering to Lessor its written notice not later than ten (10) full months (but not sooner than twelve (12) full months) prior to the end of the Extended Term. Once delivered, written notice to extend is irrevocable.

“Market Rent” as used herein, shall be that rent charged for comparable research laboratory and office space of similar age and condition in laboratory buildings the mid-Cambridge submarket as of the end of the Extended Term. If, after good faith attempts prior to the expiration of the original Term, the Lessor and Lessee cannot agree on a figure representing Market Rent, then either party, upon written notice to the other, may request appraisal and arbitration of the issue as provided in this section. Within fourteen (14) days of the request for arbitration, each party shall submit to the other the name of one unrelated individual or entity with proven expertise in the leasing of commercial real estate in greater Boston/Cambridge to serve as that party’s appraiser. Each appraiser shall be paid by the party selecting him or it. The two appraisers shall each submit their final reports to the parties within thirty (30) days of their selection making their determination as to Market Rent (subject however, to the Extension Rent Floor). The two appraisers shall meet within the next fourteen (14) days to reconcile their reports and collaboratively determine the Market Rent. They shall each make their determination in writing (subject however, to the Extension Rent Floor), including a statement if such is the case, that they are at an impasse. Such a statement of impasse shall be submitted to the parties along with the Market Rent figure which each appraiser has selected and his reasons and substantiation

therefor. The appraisers, in case of an impasse, shall also agree on one unrelated individual or entity with expertise in commercial real estate in greater Boston, who shall evaluate the reports of the two original appraisers and within fourteen (14) days of submission of the issue to him, make his own determination as to a figure representing Market Rent (subject however, to the Extension Rent Floor). The determination of this individual or entity (i.e. arbitrator) absent, fraud, bias or undue prejudice shall be binding upon the parties.

Annual Base Rent and Additional Rent during any Additional Term Extension Period shall be payable in advance, in equal monthly installments on the first day of each calendar month.

Lessee, in addition to the sums payable annually to Lessor as Annual Base Rent, shall pay to Lessor for each year of the Additional Term Extension Period, as Additional Rent, Lessee’s Allocable Percentage (as determined by the approximate total rentable space leased) for Operating Expenses, Real Estate Taxes and utilities as contemplated in Section 4 hereof.

10.	Access; Elevators; Dumpsters; Signage

Lessee shall have 24/7 access to the Total Leased Premises (with regard to the Expansion Space, such access shall be allowed following the applicable Expansion Delivery Dates), the common areas and elevators serving the Total Leases Premises, the freight elevators servicing the Building, the loading docks servicing the Building and the dumpster and/or compactor servicing the Building.

Lessor shall provide, at Lessor’s expense, building standard signage in the Building’s lobby, in any Building directory, and at the main entrance to the Total Leased Premises.

11.	Integration of Documents; Supremacy

This Second Lease Extension Agreement contains the full understanding and agreement between the parties. The parties hereto intend that this Second Lease Extension Agreement operates to amend and modify the Existing Lease, and that those documents shall be interpreted conjunctively; with any express conflict between the two to be resolved in favor of the stated terms of this Second Lease Extension Agreement. Except as modified hereby, all other terms and conditions of the Existing Lease shall remain unchanged and enforceable in a manner consistent with this Second Lease Extension Agreement. Defined terms used in this Second Lease Extension Agreement that are not otherwise defined herein shall have the definitions ascribed to such terms in the Existing Lease.

This Agreement shall be governed by the laws of the Commonwealth of Massachusetts. Any provisions deemed unenforceable shall be severable, and the remainder of this Second Lease Extension Agreement and the Existing Lease shall be enforceable in accordance with their terms.
