8. Alterations.

8.1. General Requirements.

8.1.1. Sublessee shall not make any alterations, additions or improvements to the Subleased Premises (“Alterations”) without the prior written consent of Sublessor, which consent shall not be unreasonably withheld, conditioned or delayed, and Prime Lessor. Sublessor acknowledges that Sublessee intends to make certain Alterations to prepare the Sublease Premises for Sublessee’s use (“Tenant’s Work”); such Tenant’s Work shall be performed in accordance with the Work Letter attached as Exhibit C. Sublessor hereby approves the Tenant’s Work described on Exhibit C-1 attached hereto. Prime Lessor’s Consent shall include a consent to the Tenant Work, Sublessee’s use of the Premises for laboratory uses and Prime Lessor’s agreement that that Sublessee shall not be required to remove any Alteration which is part of the laboratory installed in connection with Tenant’s Work.

All Alterations, subject to consent as provided above, shall be made at Sublessee’s sole cost and expense (except with respect to the Improvement Allowance as defined and as provided in Exhibit C with respect to Tenant’s Work), in a good and workmanlike manner, in accordance with all applicable laws and in accordance with the Prime Lease. Any ADA or other compliance requirements imposed because of or related to Alterations performed by Sublessee shall be the responsibility of Sublessee and Sublessee’s sole cost.

8.2. Removal of Alterations. Upon the expiration or sooner termination of the Sublease Term, all Alterations (including but not limited to the Tenant’s Work) shall remain on the Subleased Premises and become the property of Sublessor unless Sublessor or Prime Lessor shall give written notice to Sublessee to remove the same, which written notice shall be given (if at all) only at the time such party’s consent to the Alteration is given; provided, however that Sublessee shall be required to remove any Alteration which is part of the laboratory installed in connection with Tenant’s Work if and to the extent such removal is required by Prime Landlord, but Sublessee shall not be required to remove any alteration, which was installed or constructed prior to the term of this Sublease. Sublessee shall remove any Sublessee Alterations which

Sublessor requires that Sublessee remove, and will repair and restore any damage to the Subleased Premises caused by the installation or removal of such Alterations. Without limiting the generality of the foregoing, if required by Prime Lessor, all wiring and cabling installed by or for Sublessee, whether inside or outside the Subleased Premises, shall be removed by Sublessee (or, at Sublessor’s election, by Sublessor), at Sublessee’s sole cost and expense, at the expiration or earlier termination of the Sublease Term. If Sublessee fails to perform any of its obligations under this Section 8.2, Sublessor may perform such obligations on behalf of Sublessee, and the cost and expense thereof, together with interest at the Overdue Interest Rate from the date such costs and expenses were incurred by Sublessor, shall be paid by Sublessee to Sublessor as Additional Rent within thirty (30) days after Sublessee is billed therefor.

9. Mechanics Liens; Other Encumbrances.

9.1. Obligation to Discharge; Failure to Discharge. Sublessee shall keep the Subleased Premises, the Premises and the Land free from any liens arising out of any labor, services, materials, supplies or equipment furnished or alleged to have been furnished to Sublessee. Should any lien be made or filed in connection with the Alterations, Sublessee shall bond against or discharge the same within thirty (30) days after receiving notice thereof, regardless of the validity of the lien or claim. If Sublessee shall fail to cause such lien to be bonded against or to be discharged within such period, then, in addition to any other right or remedy which Sublessor may have, Sublessor may, but shall not be obligated to, discharge the same either by paying the amount claimed to be due or by procuring the discharge of such lien by deposit or by bonding. Any amount so paid by Sublessor and all costs and expenses incurred by Sublessor in connection therewith, together with interest at the Overdue Interest Rate from the respective dates of Sublessor’s making of the payment and incurring of the cost and expense, shall constitute Additional Rent payable by Sublessee under this Sublease and shall be paid by Sublessee to Sublessor on demand.

9.2. No Consent Implied.

Neither this Sublease nor any other writing signed by Sublessor or Prime Lessor shall be construed as evidencing, indicating, or causing an appearance that any erection, construction, alteration or repair to be done, or caused to be done, by Sublessee is or was for the immediate use or benefit of Sublessor or Prime Lessor.

10. Indemnification.

10.1 Sublessee covenants and agrees to indemnify, defend, and hold harmless Sublessor, Prime Lessor, and their respective partners, shareholders, officers, directors, agents and employees, from and against any and all claims, demands, costs, expenses, judgments, losses, suits and damages arising out of or connected with (A) Sublessee’s use of the Premises, the conduct of Sublessee’s business therein, or any activity, work or thing done, permitted or

During the Sublease Term, Sublessee shall have the right to use the furniture and equipment listed in Exhibit A attached to the form bill of sale (the “FF&E”) attached to this Sublease as Exhibit D (the “Bill of Sale”), and upon expiration of this Sublease, Sublessee shall remove the FF&E from the Subleased Premises.

Sublessee shall use not more than its Sublessee’s Share of the power from the generator and UPS and remaining power shall be available to sublessor and future tenants.

Sublessee shall have no obligation to remove or restore the back-up generator and UPS upon the expiration of the Sublease.

24.3. Security System. Sublessee shall at its cost maintain and operate the existing security monitoring and card access system serving the Building and parking areas.

Sublessee shall have no obligation to remove or restore the security system upon the expiration of the Sublease.

25. Signage.

Sublessee shall be permitted to install appropriate signage in the Building lobby, on the exterior of the Building and on the existing Building sign monument. All costs associated with the purchase, installation, maintenance and eventual removal of such signage shall be borne by Sublessee. All signage shall be subject to applicable laws, regulations and covenants to which the Land is subject and Prime Lessor’s and Sublessor’s review and approval, which shall not be unreasonably delayed or conditioned. Sublessor shall not be required to remove its existing signage in order to accommodate Sublessee’s signage.

26. Right of First Offer.

The rentable area of the Leased Premises other than the Subleased Premises (the “Remaining Space”) is available for lease and is being marketed for lease by Sublessor In the event that there then exists no uncured Default by Sublessee under this Sublease following applicable notice and cure periods, Sublessee shall have a right of first offer to lease the RFO Offered Space (as defined below), upon the following terms and conditions (the “RFO Option”). If at any time after the Commencement Date Sublessor provides a written proposal to a prosepctive third party subtenant to lease of all or any part of the Remaing Space (the “Prospective Sublessee”) and Sublessor receives a counter proposal from the Prospective Sublesse, Sublessor shall, prior to entering into a binding commitment to sublease all or any part the Remaining Space (which exact space shall be referred to as the “RFO Offered Space”) to such Prospective Sublessee, Sublessor shall provide written notice to Sublessee (the “Sublessor’s RFO Space Notice”). In no event shall Sublessor enter into a sublease of the RFO Offered Space or an assignment of the Prime Lease for the Remaining Space without first fulfilling the process and ntoice requirements outlined in this Section 26 in each instance. The Sublessor’s RFO Space Notice shall describe the terms and conditions under which Sublessor is willing to lease the RFO Space to Sublessee (provided, however, that the Base Rent to be paid by Sublessee to Sublessor with respect to the RFO Offered Space shall be the Monthly Base Rent hereunder, pro rated on a per square foot per annum basis) including but not limited to the proposed commencement date for Sublessee’s occupancy of the RFO Offered Space. The expiration date of the lease of the RFO Offered Space shall be coterminous with the expiration date of this Sublease, and the lease of the RFO Offered Space shall otherwise be on all of the terms and conditions set forth in this Sublease, including but not limited to the Bill of Sale for the furniture located within the RFO Offered Space. Sublessor shall have no obligation whatsoever to construct and/or install, at its sole cost and expense or otherwise, or to reimburse Sublessee for the cost of, any alterations or improvements of any kind to the RFO Offered Space (including, without limitation, any alterations or improvements similar or dissimilar in nature to the Sublessee improvement work) except an improvement allowance equal to $10.00 per rentable square foot of the RFO Offered Space multiplied by a fraction, the numerator of which is the number of months in the Sublease term for the sublease of the RFO Offered Space and the denominator of which is the number of months in the initial Sublease Term from the Base Rent Commencement Date to the Expiration Date. In the event that Sublessee shall desire to lease the RFO Offered Space from Sublessor on the terms and conditions set forth in the Sublessor’s RFO Space Notice, then and in such event, Sublessee shall give legally binding notice thereof to Sublessor (the “Sublessee’s RFO Space Notice”) not later than five (5) business days after the date of the Sublessor’s RFO Space Notice. If Sublessee shall not give the Sublessee’s RFO Space Notice to Sublessor on or before that date which is five (5) business days after the date of the Sublessor’s RFO Space Notice,

Sublessor shall thereupon have the right to enter into a lease with any third party for the RFO Offered Space on terms and conditions upon which Sublessor and such third-party shall agree (including, without limitation, any terms and conditions described in the preceding provisions of this paragraph) without regard to this Section 26 or the Expansion Option described in Section 27 below; provided, however, (i) Sublessor may only enter into a lease with such third party for the exact space identified in the RFO Space without being subject to the process outline in this Section and the Expansion Option, and (ii) Sublessee’s RFO Option and Expansion Option shall remain in full force and effect for any Remaining Space other than the RFO Offered Space. Notwithstanding anything to the contrary set forth elsewhere in this Sublease, Sublessee’s rights under this Section 26 are granted by Sublessor exclusively to the originally named Sublessee under this Sublease and shall not be assignable to or exercisable by any other party.

27. Option to Sublease

27.1. In the event that there then exists no uncured Default by Sublessee under this Sublease following applicable notice and cure periods, Sublessee shall have the option to lease all or any portion of the Remaining Space upon the following terms and conditions (the “Expansion Option”). If at any time after the Commencement Date Sublessee delivers written notice to Sublessor, Sublessee shall have the option to exapnd the Subleased Premises to include any or all of the Remaining Space (the “Expansion Space”), provided, however that the size and the location of the Expansion Space must be acceptable to Sublessor. The sublease of the entire balance of the first floor and a sublease of the entire second floor are deemed acceptable Expansion Spaces. In the determination of acceptable Expansion Space, Sublessor may consider the marketability of the remaing space and the cost of demising the proposed Expansion Space. The expiration date of the lease of the Expansion Space shall be coterminous with the expiration date of this Sublease, and the lease of the Expansion Space shall otherwise be on all of the terms and conditions set forth in this Subease, including but not limited to the Bill of Sale for the furniture located within the Expansion Space which Sublessor elects to transfer to Sublessor, except that the Base Rent to be paid by Sublessee to Sublessor with respect to the Expansion Space shall be the Monthly Base Rent hereunder, pro rated on a per square foot per annum basis. Sublessor shall have no obligation whatsoever to construct and/or install, at its sole cost and expense or otherwise, or to reimburse Sublessee for the cost of, any alterations or improvements of any kind to the Expansion Space (including, without limitation, any alterations or improvements similar or dissimilar in nature to the Sublessee improvement work) except an improvement allowance equal to $10.00 per rentable square foot of the Expansion Space multiplied by a fraction, the numerator of which is the number of months in the Sublease term for the sublease of the Exapnsion Space and the denominator of which is the number of months in the initial Sublease Term from the Base Rent Commencement Date to the Expiration Date. Within thirty (30) days after Sublessor’s receipt of the Sublessee’s notice exercising the Expansion Notice, the parties shall execute an amendment to this Sublease to further reflect the sublease of the additional space pursuant to this Section 27; however, the failure to execute such amendment shall not relieve or release the parties from their obligations regarding the subleasing of such additional space as provided in this Section 27. Notwithstanding anything to the contrary set forth elsewhere in this Sublease, Sublessee’s rights under this Section 27 are granted by Sublessor exclusively to the originally named Sublessee under this Sublease and shall not be assignable to or exercisable by any other party.

IN WITNESS WHEREOF, Sublessor and Sublessee have duly executed this Sublease as of the day and year first above written.

WORK LETTER

TEANT’S WORK AND IMPROVEMENT ALLOWANCE

1. Sublessee’s Work.

(A) Sublessee, at its sole cost and expense, shall perform all work necessary to prepare the Premises for Sublessee’s occupancy in accordance with plans and specifications prepared by The Richmond Group or another architect licensed by the Commonwealth of Massachusetts and approved by Sublessor, which approval shall not be unreasonably withheld, delayed, or conditioned, such plans and specifications to be subject to the reasonable approval of the Sublessor as set forth below.

(B) Sublessee shall submit to Sublessor a detailed floor plan layout together with working drawings (the “Sublessee’s Submission”) for work to be performed by Sublessee to prepare the Premises for Sublessee’s occupancy (“Sublessee’s Work”). Such floor plan layout and working drawings (the “Plans”) shall contain at least the information required by, and shall conform to the requirements of, Exhibit B of the Prime Lease. Sublessee’s submission shall include at least two (2) full sized sets and two (2) half size sets of Sublessee’s proposed layout and working drawings. Sublessor’s approval of the Plans shall not be unreasonably withheld or delayed; however, Sublessor’s determination of matters relating to aesthetic issues relating to alterations or changes which are visible outside the Premises shall be in Sublessor’s sole discretion. Sublessor shall have seven (7) business days from Sublessee’s submission made in accordance with the requirements hereof to respond to Sublessee’s request for approval thereof. If Sublessee’s submission does not comply with requirements hereof, Sublessor shall notify Sublessee of same within two (2) business days after Sublessee makes any such defective submission, which notice shall specify the respects in which such submission is defective. Any disapproval of any Plans shall set forth in reasonable detail the grounds for such disapproval along with Sublessor’s suggested corrective measures. If Sublessor disapproves of any Plans, then Sublessee shall promptly have the Plans revised by its architect to incorporate all objections and conditions presented by Sublessor and shall resubmit such plans to Sublessor not later than seven (7) days after Sublessor has submitted to Sublessee its objections and conditions. Sublessor shall have five (5) calendar days from Sublessee’s resubmission to respond to Sublessee’s request for approval thereof. Such process shall be followed until the Plans shall have been approved by the Sublessor without objection or condition. If Sublessor fails to respond in writing to Sublessee within the applicable period specified above (i.e., seven (7) business days after Sublessee’s initial submission and five (5) calendar days after any resubmission), then the submitted plans shall be deemed approved for all purposes of this Work Letter.

(C) If in connection with the review of Sublessee’s Plans by the Town of Lexington Building Commissioner at the time of Sublessee’s submission of an application for a building permit for Sublessee’s Work, it is determined by said Building Commissioner that the existing lobby/atrium and/or the existing means of egress of the Building does not comply with applicable Legal Requirements and that modification thereto is required, Sublessor, at its sole cost and expense, shall perform modification work to the lobby/atrium and/or means of egress which will bring such areas into compliance with the applicable Legal Requirements and will otherwise be done aesthetically in a manner as determined by

Sublessor. If any such modification work shall be required, the same shall be performed by Sublessor’s contractors concurrently with Sublessee’s performance of Sublessee’s Work.

(D) Notwithstanding the foregoing, Sublessee shall be solely responsible for compliance of Sublessee’s Plans with applicable Legal Requirements.

(E) Once the Plans have been approved by Sublessor, Sublessee, at its sole cost and expense, shall promptly, and with all due diligence, perform Sublessee’s Work as set forth on the Plans, and, in connection therewith, the Sublessee shall obtain all necessary governmental permits and approvals for Sublessee’s Work. Sublessor shall cooperate with Sublessee, at no out of pocket expense to Sublessor and with no liability to Sublessor, in Sublessee’s efforts to obtain such permits and approvals. All of Sublessee’s Work shall be performed strictly in accordance with the Plans and in accordance with applicable Legal Requirements (as defined below in this Work Letter) and Insurance Requirements (as defined in Section 5.14 of the Prime Lease). Sublessee shall have Sublessee’s Work performed by a general contractor first approved by Sublessor, which approval shall not be unreasonably withheld, delayed, or conditioned, which contractor shall provide to Sublessor such insurance as the Sublessor may reasonably require. Sublessor has provided to Sublessee rules and regulations relative to the performance of Sublessee’s Work and any other work which the Sublessee may perform under this Sublease and Sublessee shall abide by all such reasonable rules and regulations and shall cause all of its contractors to so abide. It shall be Sublessee’s obligation to obtain a certificate or certificates of occupancy or other like governmental approval for the use and occupancy of the Premises to the extent required by law, and Sublessee shall not occupy the Premises for the conduct of business until and unless it has obtained such approval and has submitted to Sublessor a copy of the same. However, the Base Rent Commencement Date shall be the fixed date as set forth in Section 4.1 of the Sublease. Sublessee shall also prepare and submit to Sublessor promptly after Sublessee’s Work is substantially complete a set of as-built plans in both print and electronic forms showing the work performed by Sublessee to the Premises including, without limitation, any wiring or cabling installed by Sublessee or Sublessee’s contractor for Sublessee’s computer, telephone and other communication systems.

2. Improvement Allowance.

Sublessor shall provide to Sublessee an improvement allowance of Two Hundred Fifty Thousand Six Hundred Seventy and 00/100 Dollars ($250,670.00) (being the product of (i) $10.00 and (ii) the rentable floor area of the Premises (the “Improvement Allowance”)). The Improvement Allowance shall be used and applied by Sublessee solely on account of the cost of Sublessee’s Work and the “Applicable Design Costs” (hereinafter defined). Provided that Sublessee is not in Default beyond the expiration of any applicable notice or grace period of its obligations under the Sublease at the time that Sublessee requests any requisition on account of Improvement Allowance, Sublessor shall pay to Sublessee a portion of the cost of the work shown on each requisition (as hereinafter defined) submitted by Sublessee to Sublessor within thirty (30) days of submission thereof by Sublessee to Sublessor, such portion calculated as follows: If there shall be such a Default, Sublessor shall not be obligated to continue funding the Improvement Allowance until and unless such Default is fully cured. Each requisition shall set forth the total cost of Sublessee’s Work (which term, for the purpose hereof, shall include Approved Design Costs) incurred during the period covered by such requisition. Sublessor shall pay for and with respect to each such requisition an amount equal to the product of (i) the cost of Sublessee’s Work set forth in such requisition, multiplied by (ii) a fraction, the numerator of which is

the total amount of the Sublessee Allowance and the denominator of which is the total amount of the cost of Sublessee’s Work (excluding, however, the cost of any so-called “demountable wall systems” or other portions, if any, of Sublessee’s Work toward which the Improvement Allowance may not be applied). Notwithstanding the foregoing, (a) in no event shall Sublessor be required to pay more than the total amount of Improvement Allowance, and (b) the final payment(s) of Improvement Allowance shall, if necessary for Sublessee to receive the total amount of Improvement Allowance that Sublessee is otherwise entitled to receive hereunder, be increased to the extent necessary for Sublessee to receive such total amount. For the purposes hereof, a “requisition” shall mean written documentation showing in reasonable detail the costs of the improvements then installed by Sublessee in the Premises (i.e., the Sublessee’s Work). Each requisition shall be accompanied by evidence reasonably satisfactory to Sublessor that all work covered by previous requisitions has been fully paid by Sublessee. Further the parties hereby acknowledge that the provisions of the Prime Lease shall apply to all of Sublessee’s Work. At Sublessor’s request from time to time, Sublessee shall deliver lien waivers from all contractors and subcontractors performing Sublessee’s Work. Sublessor shall have the right, upon reasonable advance notice to Sublessee, to examine Sublessee’s invoices relating to each requisition in order to verify the amount thereof. Sublessee shall submit requisition(s) no more often than monthly. For the purposes hereof, the cost to be so reimbursed by Sublessor shall consist solely of the cost of leasehold improvements and the Approved Design Costs (hereinafter defined) but not the cost of Sublessee’s personal property, trade fixtures or trade equipment or any so-called soft costs or other design costs in excess of the Approved Design Costs. The “Approved Design Costs” shall mean the architectural, engineering and space planning fees and charges actually paid by Sublessee to third party, unaffiliated architects, engineers and space planners respecting the preparation of Sublessee’s Plans but not to exceed the product of (i) $5.00 and (ii) the 24,832 square feet of Rentable Floor Area of the Premises. Notwithstanding the foregoing, Sublessor shall be under no obligation to apply any portion of the Improvement Allowance for any purposes other than as provided in this work letter, nor shall Sublessor be deemed to have assumed any obligations, in whole or in part, of Sublessee to any contractors, subcontractors, suppliers, workers or materialmen. Further, the Improvement Allowance shall only be applied towards the cost of leasehold improvements and the Approved Design Costs but in no event shall Sublessor be required to make application of any portion of the Improvement Allowance towards Sublessee’s personal property any “demountable wall systems”, if any, trade fixtures or moving expenses or on account of any supervisory fees, overhead, management fees or other payments to Sublessee, to any partner or affiliate of Sublessee or to any third party excepting “Approved Design Costs” (hereinabove defined) and payments to Sublessee’s contractors. In the event that such cost of Sublessee’s Work, including the Approved Design Costs, is less than the Improvement Allowance, Sublessee shall not be entitled to any payment or credit nor shall there by any application of the same toward Annual Fixed Rent or Additional Rent owed by Sublessee under this Sublease.

3. Quality and Performance of Work.

All construction work required or permitted by this Sublease shall be done in good and workmanlike manner in compliance with all applicable laws, ordinances, rules, regulations, statues, by-laws, court decisions, and orders and requirements of all public authorities (“Legal Requirements”) and all Insurance Requirements. All of Sublessee’s work shall be coordinated with any work being performed by or for Sublessor and in such manner as to maintain harmonious labor relations. Each party may inspect the work of the other at reasonable times and shall promptly give notice of observed defects. Each party authorizes the other to rely in connection with design and construction upon
