ARTICLE 1. GRANT

1.1 Premises. Landlord, for and in consideration of the rents herein reserved and of the covenants and agreements herein contained on the part of Tenant to be performed, hereby leases to Tenant and Tenant accepts from Landlord, certain space shown on Exhibit A attached hereto and made a part hereof, containing 3,317 rentable square feet in area (the “Premises”), situated on the third (3^rd) floor in the office building located at 111 Speen Street, Framingham, Massachusetts 01701 (the “Building”). The Premises, Building, the “Common Areas” (defined below) and the land upon which the same are located, which is legally described in Exhibit B (the “Land”), together with all other improvements thereon and thereunder are collectively referred to as the “Property.”

1.2 Common Areas. Landlord hereby grants to Tenant during the term of this Lease, a license to use, in common with the others entitled to such use, the Common Areas, subject to the rights, powers and privileges herein reserved to Landlord and Landlord’s “Rules and Regulations” (as defined in Section 7.4 below). The term “Common Areas” as used herein includes all areas and facilities outside the Premises that are provided and designated by Landlord for general non-exclusive use and convenience of Tenant, and the other tenants and occupants of the Building, from time to time. Common Areas include but are not limited to common hallways, lobbies, stairways, elevators, and other areas or facilities within the Building for the general use convenience and benefit of Tenant and other tenants and occupants of the Building; and the common parking areas associated with the Building (subject to the provisions of Section 1.3 below); the common walkways, sidewalks, landscaped areas, loading areas and driveways and areas associated with the Building.

1.3 Parking. During the “Term” of this Lease (as defined in Section 2.1), Tenant shall be entitled to use the surface parking facilities at the Property in common with other Building tenants and occupants, but such right shall be limited to four (4) non-exclusive tenant parking spaces for each 1,000 rentable square feet demised hereunder. Tenant will notify its agents, contractors, employees, licensees or invitees (the “Tenant Parties”) of this parking provision. The foregoing shall not be deemed to provide Tenant with an exclusive right to any parking spaces or any guaranty of the availability of any particular parking spaces. The Tenant’s use of the parking facilities is available on a non-exclusive first-come, first-served basis. Tenant agrees not to overburden the parking facilities and agrees to cooperate with Landlord and other Building tenants and occupants in the use of parking facilities. Landlord may designate parking facilities at the Property for the handicapped, visitors to the Building and for use by other tenants. Landlord may install signage or implement a pass or sticker system to control parking use, and may employ valet parking to meet the requirements of this Section. To the extent applicable to Tenant’s use of the parking spaces, the provisions of this Lease shall apply, including Rules and Regulations of general applicability from time to time promulgated by Landlord.

1.4 Office Furniture. During the Term, Tenant shall be permitted to use the furniture located within the Premises on the Commencement Date, an inventory of which is attached hereto as Exhibit E (the “Existing Furniture”). Tenant accepts such furniture “as-is” in its present state and condition and Landlord makes no representations or warranties with respect to same. Tenant shall take good care of and shall repair and maintain such furniture and personal property in substantially the same condition as exists on the Commencement Date, ordinary wear and tear excepted, at Tenant’s sole cost, and at all times during the Term. At the end of the Term, Tenant shall leave the Existing Furniture in the Premises. Landlord shall have

1

access to the Premises upon reasonable advance notice and during Normal Business Hours, during the ninety (90) day period immediately prior to the expiration (or sooner termination) of the Term for the purpose of bringing contractors and/or furniture vendors through the Premises in order to quote on and prepare for the removal of such furniture.

ARTICLE 2. TERM

2.1 Lease Term.

2.1.1 Commencement Date; Term. The Premises are leased for a term (the “Term”) to commence on the “Commencement Date” (as defined in Section 3.2) and shall end on the date (the “Expiration Date”) that is the last day of the thirty-sixth (36^th) full calendar month following the “Rent Commencement Date” (as defined in Section 4.1 below) unless sooner terminated as herein provided. Subject to operation of Article 3 below, the Term comprises thirty-nine (39) full calendar months plus any partial monthly period (if the Commencement Date does not occur on the first day of a calendar month).

2.1.2 Lease Year Defined. The first “Lease Year” shall begin on the Commencement Date and shall end on the last day of the twelfth (12th) full calendar month following the Rent Commencement Date. Each Lease Year thereafter shall consist of twelve (12) consecutive calendar months following the end of the immediately preceding Lease Year.

2.2 Holding Over. In the event that Tenant retains possession of the Premises, or any part thereof, after the end of the Term (by lapse of time otherwise), Tenant shall pay Landlord for each day that Tenant remains in possession of the Premises, or any part thereof, at the rate (the “Holdover Rate”) which shall be equal to one hundred fifty percent (150%) of the Annual Base Rent payable during the last month of the Lease Term, plus all Additional Rent at the rates payable during the last month of the Lease Term. Such holding over shall constitute renewal of this Lease for a period from month to month at the Holdover Rate, but if the Landlord does not so elect, no such renewal shall result notwithstanding acceptance by Landlord of any sums due hereunder after such termination; and instead, a tenancy at sufferance at the Holdover Rate shall be deemed to have been created. In addition, if such holdover continues for more than 60 days, Landlord may recover consequential damages it sustains by reason of Tenant’s retention of possession of the Premises thereafter. The provisions hereof do not limit or restrict Landlord’s rights or remedies under this Lease in the event of any holding over by Tenant.

ARTICLE 3. COMPLETION AND OCCUPANCY OF THE PREMISES

3.1 Landlord’s Work

3.1.1 Tenant’s Inspection. Landlord shall perform the work listed below (using “building standard” materials and finishes) to prepare the Premises for Tenant’s occupancy (the “Landlord’s Work”):

(a) Install new carpet within the Premises;

(b) Install new indirect lighting and ceiling tiles; and

(c) Provide new paint within the Premises.

Except for Landlord’s Work, Landlord leases the Premises to Tenant “AS IS.” Landlord makes no representations or warranties whatsoever with respect to the Premises. Tenant acknowledges that it has had full, adequate and complete opportunity to inspect the Premises, and that it is fully and completely satisfied therewith. If any repairs, improvements or work in addition to Landlord’s Work should be necessary to prepare the Premises for Tenant’s use and occupancy, Tenant shall perform such additional work at its own cost and expense, and shall comply with Article 8 in doing so.

2

3.1.2 Target Commencement Date. Landlord shall not have any obligation to make any repairs, to construct any improvements or to perform any other work to the Premises other than Landlord’s Work. Landlord shall use commercially reasonable efforts to complete Landlord’s Work and deliver possession of the Premises to Tenant on or before January 15, 2018 (the “Target Commencement Date”). In order to complete Landlord’s Work by such date, Tenant agrees to make all tenant finish selections within five (5) business days following execution of this Lease. If Landlord’s Work is not completed by such date, then the Commencement Date and the Rent Commencement Date (and Tenant’s corresponding obligation to begin paying rent hereunder) shall be delayed on a per day basis for each day until such work is so completed. Such postponement of Term commencement shall be Tenant’s sole and exclusive remedy for Landlord’s failure substantially to complete Landlord’s Work by such date. Tenant may not terminate this Lease on account thereof, nor shall Landlord have any liability to Tenant therefor. If the Commencement Date is so postponed, then the Expiration Date shall be correspondingly extended so that the length of the Term shall remain the number of years indicated in Section 2.1, notwithstanding such delay.

3.1.3 Early Access by Tenant. Landlord agrees to permit Tenant access to the Premises during the ten (10) day period immediately preceding the Target Commencement Date for the purpose of Tenant moving certain tangible personal property into the Premises. Tenant agrees to coordinate its activities with Landlord and not to interfere with any of the Landlord’s Work under construction at such time. Tenant’s use of the Premises prior to the Commencement Date shall be governed by all of the terms and conditions of the Lease other than with respect to Tenant’s obligations for payment of Rent.

3.2 Commencement Date. The Term of this Lease and the obligations of the parties hereto shall commence on a date (the “Commencement Date”) which shall be the sooner of: (a) the date that Tenant commences operation of its business in all or any portion of the Premises; or (b) the date that Landlord completes Landlord’s Work and delivers possession of the Premises to Tenant.

3.3 Tenant’s Systems. Tenant, at its sole expense, shall design, install, construct and maintain Tenant’s data, telephone, audio-visual, internet and video systems (“Tenant’s Communications Systems”) and Tenant’s furniture, equipment and security systems (collectively, the “Tenant’s Systems”) within the Premises and the related wiring within the Building necessary for the operation thereof. Landlord will permit Tenant and its agents, architects, engineers, space planners, contractors, subcontractors, suppliers and materialmen (“Tenant’s Agents and Consultants”) to have access to the Premises and the Building for the purposes of measuring and planning work related to Tenant’s Systems (at the sole risk of such parties and without liability to Landlord) for such purposes subject to the terms and conditions of this Lease. The design, plans and specifications for the wiring, cabling and equipment for Tenant’s Communication System, and its locations and connections from within the Premises to the Building risers, conduits and systems shall be subject to Landlord’s prior review and approval not to be unreasonably withheld, conditioned or delayed. Tenant shall provide Landlord with reasonable prior written notice of any construction work relating to Tenant’s Systems that involves or affects any Building systems, and all such work shall be coordinated with Landlord and subject to Landlord prior approval and supervision.

3.4 Confirmatory Amendments When the Commencement Date, Rent Commencement Date and Expiration Date hereof have been determined in accordance with the provisions set forth in this Lease, the parties hereto shall execute a document in recordable form, setting forth said dates and said document shall be deemed a supplement to and part of this Lease. The parties hereto agree to execute such confirmatory document not later than ten (10) days following the Commencement Date, but either party’s failure to do so shall not affect the validity of the determination of such dates.

ARTICLE 4. RENT AND SECURITY

4.1 Annual Base Rent.

4.1.1 Schedule of Monthly Rent Payments. Beginning on the ninety-first (91^st) day following the Commencement Date (the “Rent Commencement Date”) and continuing throughout the Term, Tenant shall pay to or upon the order of Landlord an annual rental (the “Annual Base Rent”) as set forth below which shall be payable in consecutive monthly installments on or before the first day of each calendar month in advance in the monthly amount set forth below:

Period	Annual Base Rent		Annual Base Rent per Rentable Square Foot		Monthly Base Rent
Abatement Period: (The 90-day Period beginning on Commencement Date until Rent Commencement Date)	$	0.00	$	0.00	$	0.00
Lease Year 1: (Period beginning on Rent Commencement Date and continuing for 12 full calendar months)	$	92,876.00	$	28.00	$	7,739.67
Lease Year 2	$	95,363.75	$	28.75	$	7,946.98
Lease Year 3	$	97,851.50	$	29.50	$	8,154.29

4.1.2 Manner of Payment. All payments of rent shall be made without demand, deduction, counterclaim, set-off, discount or abatement in lawful money of the United States of America. If the Rent Commencement Date should occur on a day other than the first day of a calendar month, or the Expiration Date should occur on a day other than the last day of a calendar month, then the monthly installment of Annual Base Rent for such fractional month shall be payable on such date, prorated upon a daily basis based upon a thirty (30)-day month, and all subsequent payments shall be due on or before the first day of each subsequent calendar month of the Term.

4.1.3 Abatement Period. The scheduled monthly installments of Annual Base Rent for the first three (3) months of the Term (the “Abatement Period”) shall not be due by Tenant so long as no Event of Default has occurred under this Lease, provided, however, Tenant shall be responsible for the payment of the “Electrical Charge” under Section 5.4 during the Abatement Period. Tenant shall pay all Additional Rent payable for the Abatement Period pursuant to the terms of this Lease. The entire monthly installments of Annual Base Rent otherwise due and payable for the Abatement Period shall become immediately due and payable upon the occurrence of an Event of Default by Tenant under this Lease.

4.2 Additional Rent. Tenant shall pay to Landlord all charges and other amounts required under this Lease and the same shall constitute additional rent hereunder (herein called “Additional Rent”), including, without limitation, any sums due resulting from the provisions of Article 5 hereof. All such amounts and charges shall be payable to Landlord in accordance with Section 4.3 hereof. Landlord shall have the same remedies for a default in the payment of Additional Rent as for a default in the payment of Annual Base Rent. The term “Rent” as used in this Lease shall mean the Annual Base Rent and the Additional Rent. Tenant hereby acknowledges and agrees that the obligations of Tenant hereunder shall be separate and independent covenants and agreements, that Rent shall continue to be payable in all events and that the obligations of Tenant hereunder shall continue unaffected, unless the requirement to pay or perform the same shall have been terminated pursuant to an express provision of this Lease. Landlord and Tenant each acknowledges and agrees that the independent nature of the obligations of Tenant hereunder represents fair, reasonable, and accepted commercial practice with respect to the type of property subject to this Lease. Such acknowledgments by Tenant are a material inducement to Landlord entering into this Lease.

4.3 Place of Payment. The Annual Base Rent and all other sums payable to Landlord under this Lease shall be paid to Landlord at c/o Marcus Partners, Inc., 260 Franklin Street, Suite 620, Boston, MA 02110, or at such other place as Landlord shall designate in writing to Tenant from time to time. If an Event of Default occurs, Landlord may require by notice to Tenant that all subsequent Rent payments be made by an automatic payment from Tenant’s bank account to Landlord’s account, without cost to Landlord. Tenant must

4

implement such automatic payment system within ten (10) days after Landlord’s notice. Unless specified in this Lease to the contrary, all amounts and sums payable by Tenant to Landlord pursuant to this Lease shall be deemed Additional Rent.

4.4 Terms of Payment. Tenant shall pay to Landlord all Annual Base Rent as provided in Section 4.1 above and Tenant shall pay all Additional Rent payable under Article 5 and Article 6 on the terms provided therein. Except as provided in the immediately preceding sentence and as may otherwise be expressly provided by the terms of this Lease, Tenant shall pay to Landlord, within thirty (30) days after delivery by Landlord to Tenant of bills or statements therefor: (a) sums equal to all expenditures made and monetary obligations incurred by Landlord in accordance with the terms of this Lease for Tenant’s account; and (b) all other sums of money accruing from Tenant to Landlord in accordance with the terms of this Lease.

4.5 Late Charges. If Tenant shall fail to pay any Rent within five (5) days after the date same is due and payable or if any check received by Landlord from Tenant shall be dishonored, Tenant agrees that Landlord’s actual damages resulting therefrom are difficult to fix or ascertain. As a result, Tenant shall pay to Landlord (a) an administrative fee equal to five percent (5%) per month on each unpaid monthly installment until paid, and (b) interest on the amount due from its due date until paid at the lesser of twelve percent (12%) per annum or the maximum legal rate that Landlord may charge Tenant; provided, that, on the first (1st) occasion only during each Lease Year, no such charges or interest shall be payable with respect to any delinquent payment if such payment is received by Landlord within five (5) days following written notice of such failure. Such charges shall be paid to Landlord together with such unpaid amounts as an administrative fee to compensate Landlord for administrative expenses and its cost of funds.

4.6 Letter of Credit.

4.6.1 Amount; Requirements. On the execution of this Lease, Tenant shall deliver to Landlord as security for the performance of the obligations of Tenant hereunder a letter of credit in the initial amount of [$23,219.00] (the “Initial Amount”) in accordance with this Section 4.6 (as renewed, replaced and/or reduced pursuant to this Section 4.6, the “Letter of Credit”). Tenant’s failure to timely deliver the Letter of Credit to Landlord shall constitute a default under this Lease, without the benefit of any notice or cure period under Article 13 hereof. The Letter of Credit (a) shall be irrevocable and shall be issued by a U.S. commercial bank reasonably acceptable to Landlord that has an office for presentment in the Boston, Massachusetts metropolitan area, in a form substantially similar to the form attached as Exhibit F, (b) shall require only the presentation to the issuer of a certificate of the holder of the Letter of Credit stating that Landlord is entitled to draw on the Letter of Credit pursuant to the terms of this Lease, (c) shall be payable to Landlord or its successors in interest as the Landlord, and shall be freely transferable without cost to Landlord, any such successor or any lender holding a collateral assignment of Landlord’s interest in the Lease, (d) shall be for an initial term of not less than one (1) year and contain a provision that such term shall be automatically renewed for successive one-year periods unless the issuer shall, at least sixty (60) days prior to the scheduled expiration date, give Landlord notice of such non-renewal, and (e) shall otherwise be in form and substance reasonably acceptable to Landlord.

4.6.2 Collateral Assignment by Landlord. Notwithstanding the foregoing, the term of the Letter of Credit for the final period shall be for a term ending not earlier than the date sixty (60) days after the last day of the Term. Tenant acknowledges that Landlord may be required to pledge the proceeds of the Letter of Credit to any lender holding a collateral assignment of Landlord’s interest in the Lease and agrees to provide Landlord with such documentation as Landlord may reasonably request, and to cooperate with Landlord as is necessary, to evidence the consent by the issuer of the Letter of Credit to such pledge.

4.6.3 Right to Draw Letter of Credit. Landlord shall be entitled to draw upon the Letter of Credit in part, or for its full amount (a) if Tenant shall be in default under the Lease, after the expiration of any applicable notice or cure period (or if Tenant has failed to timely pay Rent or perform any of its other obligations under the Lease and transmittal of a default notice or running of any cure period is barred or tolled by applicable law), (b) if, not less than thirty (30) days before the scheduled expiration of the Letter of Credit, Tenant has not delivered to Landlord a new Letter of Credit in accordance with this Section 4.6 (which failure shall be deemed a default without the benefit of any notice or cure period; provided, however, that

5

Landlord agrees to provide Tenant with at least five (5) days prior written notice before it draws the Letter of Credit as a result of such failure; and provided, further, however, that such default may not give rise to an Event of Default as defined herein, and with respect to any such default (i) Landlord’s sole and exclusive remedy shall be to draw upon the letter of credit as set forth above, and (ii) Landlord shall not have any of the remedies set forth in Section 13), or (c) if the credit rating of the long-term debt of the issuer of the Letter of Credit (according to Moody’s or similar national rating agency) is downgraded to a grade below investment rate), or if the issuer of the Letter of Credit shall enter into any supervisory agreement with any Governmental Authority (as defined herein), or if the issuer of the Letter of Credit shall fail to meet any capital requirements imposed by applicable law. Landlord may, but shall not be obligated to, apply the amount so drawn to the extent necessary to cure Tenant’s default under the Lease and/or make any payment due to Landlord hereunder on account of such default, including, without limitation, any unpaid Rent, any damages arising from a termination of the Lease in accordance with its terms, and for any damages arising from any rejection of this Lease in a bankruptcy proceeding commenced by or against Tenant. Any amount drawn in excess of the amount applied by Landlord pursuant to the immediately preceding sentence shall be held by Landlord as a security deposit for the performance by Tenant of its obligations hereunder. Said security deposit may be mingled with other funds of Landlord, and no fiduciary relationship shall be created with respect to such deposit, nor shall Landlord be liable to pay interest thereon. If Tenant shall fail to perform any of its obligations under this Lease, Landlord may, but shall not be obliged to, apply the security deposit to the extent necessary to cure the default and/or make any payments due to Landlord hereunder on account of such default. After any such application by Landlord of the Letter of Credit or security deposit, Tenant shall reinstate the Letter of Credit to the amount originally required to be maintained hereunder, upon demand (and, upon such reinstatement, Landlord shall return any cash security deposit then being held by Landlord to Tenant). Within sixty (60) days after the expiration or sooner termination of the Term, the Letter of Credit and any security deposit, to the extent not applied, shall be returned to the Tenant, without interest, For purposes of this Section 4.6, a default shall also include any default that is prevented or delayed from ripening into a default due to Landlord’s inability to give any required notice or the tolling of any grace or cure period caused by any stay or injunction arising from the bankruptcy of Tenant.

4.6.4 Transfer of Property; Release of Landlord. In the event of a sale of the Property or lease, conveyance or transfer of the Property, Landlord shall have the right to transfer the security to the transferee (“New Landlord”). Upon such transfer, and provided that such New Landlord’s acknowledges in writing its receipt of, and responsibility to Tenant for, such security, Landlord shall thereupon be released by Tenant from all liability for the return of such security; and Tenant agrees to look to the New Landlord solely for the return of said security. The provisions hereof shall apply to every transfer or assignment made of the security to a New Landlord. Tenant further covenants that it will not assign or encumber or attempt to assign or encumber the Letter of Credit or the monies deposited herein as security, and that neither Landlord nor its successors or assigns shall be bound by any assignment, encumbrance, attempted assignment or attempted encumbrance. It is agreed that the provisions hereof shall apply to every transfer or assignment of said Letter of Credit to New Landlord.

5.2 Payment of Taxes. Tenant shall pay, as Additional Rent, Tenant’s Share of all Taxes payable in respect of any Tax Year falling wholly or partially within the Term, to the extent that Taxes for any such period shall exceed the Base Taxes (which payment shall be adjusted by proration with respect to any partial Tax Year). Landlord, at its option, may require Tenant to make monthly payments on account of Tenant’s Share of Tax Increases for Tax Years following the Base Tax Year. The monthly payments shall be one-twelfth (1/12th) of the amount of Tenant’s Share of Tax Increases and shall be payable on or before the first day of each month during the Term, in advance, in an amount estimated by Landlord and billed by Landlord to Tenant; provided, that, Landlord shall have the right initially to determine such monthly estimates and to revise such estimates from time to time. Alternatively, Landlord may bill Tenant upon Landlord’s receipt of its bill for Taxes from the Governmental Authorities issuing such bills, and in such case, Tenant shall pay Landlord its Tenant’s Share of Taxes, based upon such bill, within fifteen (15) days following its receipt of Landlord’s invoice therefor.

5.3 Payment of Operating Expenses. Tenant shall pay to Landlord, as Additional Rent, Tenant’s Share of all Operating Expenses in respect of each Expense Year to the extent Operating Expenses for each such Expense Year shall exceed Base Expenses.

After the expiration of the Base Expense Year and each Expense Year, Landlord shall prepare and furnish Tenant with Landlord’s Statement showing the Base Expenses or the Operating Expenses incurred during such Expense Year. Within thirty (30) days after receipt of Landlord’s Statement for any Expense Year setting forth Tenant’s Share of any Expense Increase attributable to such Expense Year, Tenant shall pay Tenant’s Share of such Expense Increase (less the amount of estimated payments paid by Tenant on account thereof) to Landlord as Additional Rent, and Landlord shall refund to Tenant any overpayments made by Tenant pursuant to Section 5.6 hereof.

5.4 Payment of Electric Expense.

5.4.1 Base Electric Charge. During any period that the “Electrical Charge” (as defined herein) is not separately metered or submetered with respect to the Premises, then, in addition to Annual Base Rent and other Additional Rent provided by this Lease, as Additional Rent as hereinafter provided, all “Electric Service” (as defined in Section 6.1 below) used or consumed in connection with lighting and general electric services in the Premises, exclusive of any space for which a separate meter has been provided to measure such use and consumption (the “Electrical Charge”). Tenant acknowledges and agrees that, as of the Commencement Date, the Electrical Charge for calendar year 2015 shall be payable at the rate of $1.75 and 00/100 Dollars ($1.75) per square foot per annum for each square foot contained in the Premises (the “Base Electric Charge”) payable as Additional Rent, in equal monthly installments of Four Hundred Eighty-Three and 00/100 Dollars ($483.73) commencing on the Commencement Date and continuing on the first (1^st) day of each month thereafter occurring during the Term. Landlord has established the Base Electric Charge based upon a survey report of a third party engineering consultant and the presently installed electric facilities in the Premises and the current rate of payment established by the utility company for such electric service.

10

The Base Electric Charge relates to Tenant’s lights, plugs, receptacles and general office equipment; but does not include electric current for any of Tenant’s special equipment and facilities which shall be payable by Tenant as provided in Section 6.6 below.

5.4.2 Rate Increases; Estimated Payments. During the Term (at any time after the date of this Lease), Tenant’s rate of payment shall increase from time to time based upon any increase in and the rate at which Landlord purchases electric energy from the public utility company supplying electric current for the Building, or any tax is imposed on Landlord’s receipt from the sale or resale of electrical energy to Tenant by any Federal State or Municipal authority, or any increase in any charges incurred or taxes payable by Landlord in connection therewith, or any increase in Tenant’s proportionate share of the actual tenant electrical expense for the Building. Following any such rate increase or other change affecting the Base Electric Charge and written notice to Tenant, this Lease shall automatically be modified by increasing the Additional Rent payable hereunder for the balance of the Lease Term in accordance with this Section and, as evidence of such modification, notice of any such increase in the Electrical Charge shall be delivered by Landlord to Tenant. Any such increase in the Additional Rent shall be effective as of the date of any such increase in cost or other charge to Landlord and shall be retroactive to such date, if necessary. In any such case, Landlord shall have the right to furnish Tenant with an estimate (which estimate may be changed by Landlord from time to time) of the resulting increased payment amount in addition to the Base Electric Charge, and, upon and after the furnishing of any such estimate, Tenant shall, in addition to the Base Electric Charge, pay to Landlord one-twelfth (1/12) of the increased amount, payable on the first (1^st) day of each month during the term, in advance. Tenant’s Electrical Charge shall also be subject to increase based upon Landlord’s determination of a change in Tenant’s electric consumption as determined by Landlord’s independent consultant. Landlord shall also have the right to issue supplemental billing to Tenant from time to time for the Electrical Charge to account for any increases in electric consumption or increases in the cost of providing such Electric Service (as set forth above).

5.4.3 Reconciliation of Estimated Payments. After the end of each calendar year during which Tenant shall have made any payments based upon Landlord’s estimate under Section 5.4.2 above, and after the end of the Term, Landlord shall submit to Tenant a statement of the actual increase in Electrical Charge for the preceding calendar year over the Base Electric Charge, and if the Electrical Charge so stated for such period is (i) more than the amount paid for such period, Tenant shall pay to Landlord the deficiency within thirty (30) days after submission of such statement, or (ii) less than the amount paid for such period, Tenant shall be entitled to a credit in the amount of such excess against amounts next coming due under this paragraph (or a payment from Landlord within thirty (30) days in the case of the end of the Term). Any such adjustment shall survive the expiration or earlier termination of the Term.

5.5 Landlord’s Statements.

5.5.1 Landlord’s Statements and Tenant’s Inspection Rights. Landlord will deliver Landlord’s Statements to Tenant during the Term. Landlord’s delay or failure to render Landlord’s Statement with respect to the Base Expense Year, any Expense Year or any Tax Year beyond a date specified herein shall not prejudice Landlord’s right to render a Landlord’s Statement with respect to that or any subsequent Expense Year or subsequent Tax Year. The obligations of Landlord and Tenant under the provisions of this Article with respect to any Additional Rent incurred during the Term shall survive the expiration or any sooner termination of the Term. If Landlord fails to give Tenant a statement of projected Operating Expenses prior to the commencement of any Expense Year, Tenant shall continue to pay Operating Expenses in accordance with the previous statement, until Tenant receives a new statement from Landlord.

5.5.2 Tenant’s Right to Audit. During the sixty (60)-day period after receipt of any Landlord’s Statement (the “Review Period”), Tenant may, upon prior notice to Landlord, inspect and audit Landlord’s records relevant to the cost and expense items reflected in such Landlord’s Statement at a reasonable time mutually agreeable to Landlord and Tenant during Landlord’s usual business hours at the management office where such records are maintained. Tenant shall be entitled to retain an independent company or certified public accountant to review Landlord’s relevant records to determine if the proper amount of Additional Rent was charged to Tenant for such period, provided that such company or accountant must be employed on a regular fee for services basis and not a contingent fee basis. Each Landlord’s

11

Statement shall be conclusive and binding upon Tenant unless within sixty (60) days after receipt of such Landlord’s Statement Tenant shall have completed such inspection and audit and shall notify Landlord that it disputes the correctness of Landlord’s Statement, specifying the respects in which Landlord’s Statement is claimed to be incorrect. If such audit or review reveals that Landlord has overcharged Tenant, then within fifteen (15) days after the results of such audit are made available to Landlord, Landlord shall reimburse Tenant the amount of such overcharge. If the audit reveals that Tenant was undercharged, then within fifteen (15) days after the results of the audit are made available to Tenant, Tenant shall reimburse Landlord the amount of such undercharge. If Landlord desires to contest such audit results, Landlord may do so by submitting the results of the audit to arbitration pursuant to Section 13.9 of the Lease within sixty (60) days of receipt of the results of the audit, and the arbitration shall be final and binding upon Landlord and Tenant. Tenant agrees to pay the cost of such audit, provided that, if the audit reveals that Landlord’s determination of such Additional Rent as set forth in any statement sent to Tenant was in error in Landlord’s favor by more than five percent (5%), Landlord shall pay the reasonable cost of such audit. Pending the determination of such dispute as hereinafter provided, Tenant shall pay Additional Rent in accordance with the applicable Landlord’s Statement, and such payment shall be without prejudice to Tenant’s position. All inspections and audits of Landlord’s books and records and any arbitration shall be subject to a confidentiality agreement reasonably acceptable to Landlord.

5.6 Adjustments. If the actual amount of Tenant’s Share of the Expense Increases for any Expense Year or Tenant’s Share of Tax Increases for any Tax Year exceeds the estimated amount thereof paid by Tenant for such Expense Year or Tax Year, then Tenant shall pay to Landlord the difference between the estimated amount paid by Tenant and the actual amount of such Additional Rent payable by Tenant. This Additional Rent payment shall be due and payable within thirty (30) days following delivery of Landlord’s Statement. If the total amount of estimated payments made by Tenant in respect of Tenant’s Share of Expense Increases for such Expense Year or Tenant’s Share of Tax Increases for any Tax Year shall exceed the actual amount of such Additional Rent payable by Tenant, then such excess amount shall be credited against the monthly installments of Additional Rent due and payable from Tenant to Landlord hereunder until such amount shall have been refunded in full to Tenant. Any excess payments made by Tenant during the Term that have not been so applied and are outstanding at the end of the Term shall be paid to Tenant promptly following delivery of Landlord’s Statement for the final Expense Year and final Tax Year, as applicable. Even though the Term has expired and Tenant has vacated the Premises, when final determination is made of Tenant’s Share of Expense Increases or Tax Increases for the year in which this Lease terminates, Tenant shall pay any increase due over the estimated Expense Increases or Tax Increases paid within fifteen (15) days after Landlord’s delivery of Landlord’s Statement therefor.

Landlord agrees to furnish or cause to be furnished to the Premises the utilities and services described herein, subject to the conditions and in accordance with the standards set forth herein. Landlord’s failure to furnish any of such services when such failure is caused by accidents, the making of repairs, alterations or improvements, labor difficulties, difficulty in obtaining adequate supply of fuel, electricity, steam, water or other service or supplies from the sources from which they are usually obtained for the Building, or governmental constraints or any other cause beyond Landlord’s reasonable control, shall not result in any liability to Landlord. Tenant shall not be entitled to any abatement or reduction of rent by reason of such failure, no eviction of Tenant shall result from such failure and Tenant shall not be relieved from the performance of any covenant or agreement in this Lease. In the event of any failure, stoppage or interruption thereof, Landlord shall diligently attempt to resume service promptly.

6.2 Additional Services. If Tenant requires any additional work or service, as described above, including services furnished outside Normal Business Hours specified above, Landlord may, on terms to be agreed, upon reasonable advance notice by Tenant, furnish such additional service and Tenant agrees to pay Landlord such charges as may be agreed upon, including any tax imposed thereon, but in no event at a charge less than Landlord’s actual cost plus overhead for such additional service and, where appropriate, a reasonable allowance for depreciation of any systems being used to provide such service. Landlord shall impose such charges and may establish reasonable rules and regulations for any such additional services, including the following: (a) the use of any heating, air-conditioning, ventilation, electric current or other utility services or equipment by Tenant after Normal Business Hours (“Overtime HVAC”); (b) the use or consumption of any other building services, supplies or utilities after Normal Business Hours and any unanticipated, additional costs incurred by Landlord to operate the Building after Normal Business Hours as a result thereof; (c) additional or unusual janitorial services required because of any non-building standard improvements in the Premises, the carelessness of Tenant, the nature of Tenant’s business (including the operation of Tenant’s business after Normal Business Hours); and (d) the removal of any refuse and rubbish from the Premises except for discarded material placed in wastepaper baskets and left for emptying as an incident to Landlord’s normal cleaning of the Premises in accordance with Exhibit C.

This amount shall constitute Additional Rent and shall be payable in accordance with Section 4.4.

13

6.3 Excessive Current.

6.3.1 Prohibited Activities. Tenant shall comply with the conditions of occupancy and connected electrical load reasonably established by Landlord for the Building; and Tenant’s use of electrical energy in the Premises shall not, at any time, knowingly exceed the capacity of the existing feeders or wiring installations then serving the Premises. Tenant shall not, without Landlord’s prior consent in each instance, connect air conditioning equipment, major appliances (excluding a residential size refrigerator/freezer, coffee makers, microwave ovens and other similar food preparation appliances) or heavy duty equipment (“High Usage Equipment”) to the Building’s electrical system.

Tenant shall not, without prior consent of Landlord in each instance, make or perform, or permit the making or performing of, any alteration to wiring installations or other electrical facilities in or serving the Premises or any additions to the electrical fixtures, machines, equipment or other appliances in the Premises which utilize electrical energy.

6.3.2 Landlord’s Right to Survey Usage. Landlord may survey Tenant’s use of services from time to time. Tenant shall pay Landlord all costs arising out of any excess use or other connection of High Usage Equipment (which as defined above, excludes a residential size refrigerator/freezer, coffee makers, microwave ovens and other similar food preparation appliances, and for avoidance of doubt also excludes office copiers, personal computers and facsimile machines), including the cost of all repairs and alterations to the Building’s mechanical and electrical systems (including the installation of meters) and the cost of additional electricity made available to Tenant, if any. Such costs shall constitute Additional Rent and Tenant shall pay such costs pursuant to Section 4.4.

6.3.3 Metering of Excess Use. If Tenant shall require water or electric current in excess of that usually furnished or supplied for use of the Premises as normal office use, Tenant shall procure the prior written consent of Landlord for the use thereof, which Landlord may refuse, and if Landlord does consent, Landlord may cause a water meter or electric current meter to be installed so as to measure the amount of such excess water and electric current. The cost of any such meters shall be paid for by Tenant. Tenant agrees to pay to Landlord within five (5) business days of Landlord’s demand, the cost of all such excess water and electric current consumed (as shown by said meters, if any, or, if none, as reasonably estimated by Landlord) at the rates charged for such services by the local public utility or agency, as the case may be, furnishing the same, plus any additional expense incurred in keeping account of the water and electric current so consumed.

6.4 Maintenance of Common Areas. The manner in which the Common Areas are maintained and operated and the expenditures therefor shall be at the sole discretion of Landlord and in accordance with the standards of comparable first class buildings in Middlesex County. Landlord reserves the right from time to time to (a) make changes in the shape, size, location and appearance of the land and improvements which constitute the Common Areas, provided that Landlord shall not materially impair the Tenant’s ability to operate its business, except temporary impairments required by said changes, which Landlord shall use its best efforts to minimize (both in scope and duration), and which in any case shall not exceed two (2) consecutive business days; (b) make such improvements, alterations and repairs to the Common Areas as may be required by governmental authorities or by utility companies servicing the Building; (c) construct, maintain and operate lighting and other facilities on all said areas and improvements; (d) subject to Tenant’s rights pursuant to Section 1.3, grant exclusive parking rights to Building tenants; and (e) to add or remove improvements, amenities and facilities to or from the Common Areas.

14

the Common Areas to such extent as may be legally sufficient, in the opinion of Landlord’s counsel, to prevent a dedication thereof or the accrual of rights of any person or of the public therein; provided, however, Landlord shall do so at such times and in such manner as shall minimize any disruption to Tenant to the extent reasonably possible.

6.5 Access to Premises.

6.5.1 Landlord’s Right of Entry. Landlord shall have the right to enter the Premises without abatement of Rent at all reasonable times upon reasonable prior notice to Tenant (except in emergencies when no advance notice shall be required), (a) to supply any service to be provided by Landlord to Tenant hereunder, (b) to show the Premises to Landlord’s Mortgagee (not more than once per year), and to prospective purchasers, and mortgagees, and, during the last six months of the Term or after an Event of Default only, to prospective tenants, (c) to inspect, alter, improve or repair the Premises and any portion of the Building, and (d) to introduce conduits, risers, pipes and ducts to and through the Premises, provided that in exercising any such right, Landlord will cause all such conduits, risers, pipes and ducts to be placed above dropped ceilings, within walls, or below floors or in closets, to the extent reasonably practicable. In conducting any such activities, Landlord shall use reasonable efforts not to disrupt the conduct of Tenant’s business operations.

6.5.2 Tenant’s Keys. For each of the purposes stated above in this Section 6.5, Landlord shall at all times have and retain the keys and Tenant’s security access codes with which to unlock all of the doors in, upon and about the Premises, excluding Tenant’s vaults and safes, or special security areas, and Landlord shall have the right to use any and all means that Landlord may deem necessary or proper to open said doors in an emergency, in order to obtain entry to any portion of the Premises. Landlord and its agents and representatives shall have the right to enter upon the Premises for any and all of the purposes set forth in this Article and may exercise any and all of the foregoing rights without being deemed guilty of a forcible or unlawful entry into, or a detainer of, the Premises, or an eviction, actual or constructive of Tenant from the Premises, or any portion thereof, if reasonably necessary to comply with any governmental statute, ordinance or building, fire or other code.

6.6 Tenant Responsible for Supplemental Equipment.

6.6.1 Supplemental Air Conditioning Units. In the event that Tenant makes any permitted Alterations to the Premises that include the installation of one or more supplemental air conditioning units to cool non-standard, heat-producing equipment or facilities in the Premises, (the “Supplemental HVAC Equipment”), such as equipment located in a computer server room or other areas of the Premises dedicated to the operation of such heat-producing equipment, then Tenant agrees that Tenant, at its expense, shall be responsible for the operation, maintenance, repair, and replacement of all such Supplemental HVAC Equipment, and payment, as Additional Rent, of all consumption costs and charges for all electricity, energy, and other utilities used in connection therewith and the installation of metering equipment to measure its utility consumption.

6.6.2 Consumption Charges and Billing. Tenant shall pay, as Additional Rent, the full costs of all electrical and other energy charges associated with the operation of such Supplemental HVAC Equipment plus a 3% administrative charge thereon (the “Supplemental Units Utility Charge”). The energy consumption charge for any such Supplemental HVAC Equipment shall be determined and billed by Landlord to Tenant on a monthly or quarterly basis in amounts that are based upon Landlord’s reasonable estimate of the energy consumption by the Supplemental HVAC Equipment on an annual average basis, taking into account, the then prevailing rates charged by the applicable utility companies, the space layout, rentable area of the Premises, occupancy load, hours of operation of such Supplemental HVAC Equipment and other reasonable factors, plus the administrative charge. Tenant shall have the option to install, at Tenant’s expense, a sub-meter to measure the energy usage of its Supplemental HVAC Equipment, subject to Landlord’s right of prior approval of the type and model of sub-metering equipment, the proposed location and wiring plan, thereof and the plans and specifications therefor. In such case, Landlord will obtain periodic meter readings and have the right to bill Tenant for such energy consumption on a monthly or other periodic basis (as determined by Landlord) based upon the quantity of consumption shown on the sub-meter and the

15

then prevailing rates charged by the applicable utility companies, plus such administrative charge. Landlord’s invoice for such energy usage by the Supplemental HVAC Equipment shall be due and payable within twenty (20) days following Landlord’s delivery of its invoice.

6.7 Landlord’s Right to Install Supplemental HVAC Equipment. Wherever heat-generating machines or equipment are used by Tenant in the Premises which affect the temperature otherwise maintained by the air conditioned systems or Tenant allows occupancy of the Premises by more persons that the heating and air conditioning system is designed to accommodate, in either event, whether with or without Landlord’s approval, Landlord reserves the right to install supplementary heating and/or air conditioning units in or for the benefit of the Premises and the cost thereof, including the cost of installation and the cost of operations, repair, maintenance and replacement (and the energy costs related thereto) shall be paid by Tenant to Landlord within five (5) business days of Landlord’s delivery of written demand.

ARTICLE 7. CONDUCT OF BUSINESS BY TENANT

7.1 Permitted Use.

7.1.1 General Office Use. The Premises shall be used and occupied for general office purposes and for no other use. Tenant, at its expense, shall obtain and maintain in full force and effect any and all licenses and permits necessary for its use of the Premises. Tenant shall not use or occupy, or permit the use or occupancy of, the Premises or any part thereof for any use other than the sole use specifically set forth above or in any illegal manner, or in any manner that, in Landlord’s judgment, would adversely affect or interfere with any services required to be furnished by Landlord to Tenant or to any other tenant or occupant of the Building, or with the proper and economical rendition of any such service, or with the use and enjoyment of any part of the Building by any other tenant or occupant. Tenant agrees that it will not exceed the maximum floor bearing capacity for the Premises.

7.1.2 Prohibited Uses and Activities. Tenant will not (a) make or permit any occupancy or use of any part of the Premises for any hazardous, offensive, dangerous, noxious or unlawful occupation, trade, business or purpose or any occupancy or use thereof that is contrary to any law, by-law, ordinance, rule, permit or license, (b) cause, maintain or permit any nuisance in, at or on the Premises, and (c) commit any waste. Tenant agrees not to permit any occupancy or use of the Premises nor to engage in any other activity in the Building which would materially interfere with telecommunications, computer, or utility systems, installations, or services of other tenants or occupants so long as the same are of a type customarily found in first class office buildings. If noises, vibrations, odors, operating methods, or conditions of cleanliness of the Premises or any appurtenance thereto materially interfere with first class office uses of other occupied areas in the Building, Tenant shall undertake such additional protective measures as may be necessary to eliminate the material interference (such as additional noise or vibration damping or additional venting). Tenant shall keep all such areas of the Premises clean at all times and all trash, refuse and garbage from a cafeteria or similar facility shall be collected, removed and stored in a manner reasonably approved by Landlord.

Tenant, at its expense, shall timely comply with all orders and directions of Governmental Authorities for the correction, prevention and abatement of any violations in the Premises caused or permitted by, or resulting from the Tenant’s use, occupancy or operations at the Premises or resulting from any such Alterations to the Premises. Notwithstanding anything in this Lease to the contrary, Tenant shall not be responsible for making any Alterations or improvements to remedy, nor bear any costs or expenses relating to, any violations of Laws which existed prior to the Commencement Date or which are not caused by the use or occupancy or manner of use, occupancy or operation of the Premises by Tenant or any Tenant Parties or by any Alterations to the Premises made by Tenant or any Tenant Parties; which responsibility, as between Tenant and Landlord, shall be Landlord’s, and Landlord, at Landlord’s sole expense, shall promptly make all repairs, replacements, Alterations, or improvements needed in connection therewith.

7.3.2 Landlord’s Compliance Obligations. Landlord shall comply with all Laws in effect from time to time during the Term that shall impose any duty on Landlord with respect to the Building, Common Areas, or the Property, excluding any matters that are Tenant’s responsibility under this Lease or the responsibility of other tenants of the Building. The Property and any future improvements thereon will conform upon completion to all Laws, including, without limitation, the requirements of Title III of the ADA. Notwithstanding anything to the contrary contained herein, Tenant shall be responsible for legal compliance with all Laws, including the requirements of the ADA, with respect to (a) any and all requirements on account of Tenant’s use of, or operations in, the Premises, and (b) all Alterations designed or constructed by Tenant or any Tenant Parties.

7.4 Landlord’s Rules and Regulations. Tenant shall observe and comply with the rules and regulations attached to this Lease as Exhibit D with respect to the Property, and all reasonable modifications thereof and additions thereto from time to time put into effect by Landlord, provided that the same are generally applicable to all tenants of the Building and are not discriminatory against Tenant (the “Rules and Regulations”). Tenant shall not use or permit the use of the Premises in any manner that will create waste or a nuisance, or which shall tend to unreasonably disturb other tenants of the Building. Landlord shall not be responsible to Tenant for the nonperformance of any of the Rules and Regulations by any other tenants or occupants of the Building. Landlord shall use reasonable efforts to enforce the Rules and Regulations in a fair and non-discriminatory manner. In the event of an express and direct conflict between the terms, covenants, agreements and conditions of this Lease and the terms, covenants, agreements and conditions of such Rules and Regulations, as modified and amended from time to time by Landlord, this Lease shall control.

Any claim to, or lien upon, the Premises or the Building arising from any act or omission of Tenant shall accrue only against the leasehold estate of Tenant and shall be subject and subordinate to the paramount title and rights of Landlord in and to the Premises and the Property. If any mechanics’ or other lien shall be filed against the Premises or the Property purporting to be for labor or material furnished or to be furnished at the request of the Tenant, then Tenant shall at its expense cause such lien to be discharged of record by payment, bond or otherwise, within thirty (30) days after the filing thereof.

Tenant shall not handle, use, generate, store, transport, dispose, discharge, release, spill or leak any “Hazardous Substances” (as defined below), nor permit any Tenant Parties to engage in any such activities, in, above, on or under the Premises or the Property. Notwithstanding the foregoing, Tenant may handle, store, use and dispose of small quantities of Hazardous Substances (such as aerosol cans containing insecticides, toner for copies, solvents and the like) to the extent customary and necessary for the permitted use of the Premises for general office purposes; provided that (a) Tenant shall always handle, store, use and dispose of any such Hazardous Substances in a safe and lawful manner in compliance with all Environmental Laws, the fire protection requirements of any Building insurers and the terms and conditions of this Lease, and (b) Tenant shall comply with, and maintain adequate evidence of, all record keeping, training, labeling and storage requirements prescribed by the Environmental Laws and deliver copies of the same to Landlord promptly, upon request. To the extent that any Hazardous Substances become “Hazardous Waste” (as defined by the Environmental Laws, Tenant shall immediately remove the Hazardous Waste from the Property).

7.6.3 Remediation. If any Hazardous Substance is released, discharged or disposed of, or permitted by the affirmative action of Tenant to spill, leak or migrate, in violation of the foregoing provisions of this Article 7 by Tenant or any Tenant Parties, Tenant shall immediately, properly and in compliance with applicable Laws, clean up and remove the Hazardous Substance from the Premises and any other affected property and clean or replace any affected personal property (whether or not owned by Landlord), at Tenant’s expense (without limiting Landlord’s other remedies therefor). Such clean up and removal work shall be subject to the provisions thereof including, without limitation, Landlord’s prior written approval, and any testing, investigation, feasibility and impact studies, and the preparation and implementation of any remedial action plan required by any court or regulatory authority having jurisdiction or reasonably required by Landlord. Tenant shall sign any disposal forms, manifests, bills of lading or reports as the generator of the waste that is subject to the remediation, provided that Landlord shall have the right to review and approve such document reasonably in advance of Tenant’s signing the same. Notwithstanding the foregoing, Landlord reserves the right to notify Tenant that it will conduct the remediation and, in such case, Landlord shall remediate such condition and Tenant shall reimburse Landlord for all costs and expenses upon written demand by Landlord (with interest thereon at the rate described in Section 4.5).

7.6.4 Fees, Taxes, Fines and Remedies. Tenant shall pay, prior to delinquency, any and all fees, taxes (including excise taxes), penalties and fines arising from or based on Tenant’s activities involving Hazardous Substance on or about the Premises, and shall not allow such obligations to become a lien or charge against the Premises, Property or Landlord.

Tenant agrees to cooperate with Landlord and its consultants and provide such related information concerning Tenant’s operations and legal compliance matters as Landlord may reasonably request. Tenant agrees to sign any subordination agreements required for an environmental land use restriction for the Property in connection with a remediation of the Property in accordance with applicable Environmental Laws; provided that such land use restriction does not impair Tenant’s use of the Premises or its parking facilities for the purposes stated in Section 7.1 above and does not result in an increase in Tenant’s Lease obligations or liabilities.

Tenant agrees that breach of the representations and warranties set forth in this Section 7.8 shall at Landlord’s election be a default under this Lease for which there shall be no cure. This Section 7.8 shall survive the termination or earlier expiration of the Lease.

ARTICLE 8. ALTERATIONS, IMPROVEMENTS AND SIGNAGE

8.1 Landlord’s Obligations. Landlord will maintain in good repair, reasonable wear and use, (except casualty and condemnation which shall be governed by Article 10 and Article 11, respectively) including any necessary replacements (except those matters included as Tenant’s obligations under Section 8.2 below): (a) all structural components of the Building and Common Areas, including, without limitation, the foundation, exterior and load-bearing walls, exterior windows and doors, roof, and the structural floor slabs; (b) the Building Systems (defined below in Subsection 8.3.1) serving the Building (excluding any Tenant installations, fixtures and HVAC equipment (including any Supplemental HVAC Equipment) that are dedicated to Tenant’s exclusive use which shall be Tenant’s responsibility). The cost of this maintenance, repair and replacement (as necessary) shall be included in Operating Expenses and shall be subject to reimbursement under Article 5 hereof to the extent provided therein. Maintenance and repair expenses caused by Tenant’s willful misconduct or negligent acts or omissions shall be paid directly to Landlord by Tenant in accordance with Section 4.4, and shall not constitute an Operating Expense. At Tenant’s sole cost and expense, Landlord agrees to maintain, in good order, condition and repair, all plumbing facilities and electrical fixtures and devices which are affixed to the Building (including replacement of all lamps, starters and ballasts) and located within the Premises; and Tenant shall pay any such sums invoiced by Landlord for such services as Additional Rent.

8.2 Tenant’s Obligations. Tenant shall, at all times during the Term, and at Tenant’s cost and expense, keep the Premises in at least the same condition as when it was tendered to Tenant on the Commencement Date, and shall make all repairs and replacements necessary to preserve the Premises in such condition, and in a clean, safe and sanitary condition, in each such case excepting casualty, condemnation or normal wear and tear, and in compliance with all Laws. Except as otherwise provided in Section 8.1 above, Tenant shall maintain, at its own expense, in at least the same condition as when it was tendered to Tenant on the Commencement Date, to Landlord’s reasonable satisfaction, all installations, fixtures and HVAC equipment dedicated to Tenant’s exclusive use, including any Supplemental HVAC Equipment (whether or not located within the Premises). Subject to Section 7.3 above, Tenant shall, at its sole expense, promptly comply with all governmental orders and directions for the correction, prevention or abatement of any violations or nuisances in or upon, or connected with, the Premises. Tenant shall repair, at its cost, all deteriorations or damages to the Property occasioned by its negligent acts or omissions or willful misconduct. If Tenant does not make such repairs to the Building within twenty (20) days following notice from Landlord, Landlord may, but need not, make such repairs, and Tenant shall pay the cost thereof as provided in Section 8.7 hereof.

8.3 Tenant’s Alterations.

8.3.1 Landlord’s Consent to Alterations. Tenant shall not make or permit any improvements, installations, alterations or additions, including, but not limited to, the attachment of any fixtures or equipment in, on or to the Premises or any part thereof, without the prior written consent of Landlord (“Alterations”). Notwithstanding the foregoing, Landlord’s prior written

20

consent shall not be required for Alterations to the Premises which do not involve or affect the structural portions of the Premises or the Building (the “Building Structure”) or any of the Building’s HVAC, mechanical, electrical, telecommunications, cabling, plumbing or other systems or equipment (the “Building Systems”) or the interior walls or corridors within the Premises, and which do not require a building permit and which do not exceed $20,000.00 in the aggregate on an annual basis (“Permitted Alterations”); provided, however that Tenant must provide at least ten (10) days prior written notice (with a reasonably detailed description of the scope and cost thereof and the identity of the contractors performing such work) to Landlord of such proposed work in the Premises, and must promptly provide Landlord with any related information reasonably requested by Landlord.

8.3.2 Construction Standards. All Alterations made by or on behalf of Tenant shall be made and performed: (a) by contractors or mechanics approved by Landlord (except no such approval shall be required with respect to Permitted Alterations), who shall carry liability insurance of a type and in such amounts as Landlord shall reasonably require, naming Landlord and Tenant as additional insureds, (b) in a good and workmanlike manner in compliance with all Laws, (c) so that same shall be at least equal in quality, value, and utility to the original work or installation and shall be in conformity with Landlord’s building standard specifications in effect at such time, (d) in accordance with all Laws, and (e) except with respect to Permitted Alterations, pursuant to plans, drawings and specifications (“Tenant’s Plans”) which have been reviewed and approved by Landlord prior to the commencement of the repairs or replacements and approved by, and filed with, all applicable governmental authorities (the “Construction Standards”). In any event Landlord may charge Tenant a reasonable construction management fee, not to exceed 2% of the cost of such work, to cover its overhead as it related to such proposed work, plus third-party costs actually incurred by Landlord in connection with the proposed work and the design thereof (with no mark-up or profit to Landlord), with all such amounts being due five (5) days after Landlord’s written demand.

8.3.3 Insurances; Taxes. Tenant shall, prior to construction, provide the additional insurance required under Article 9 in such case, and also all such assurances to Landlord as Landlord shall reasonably require to assure payment of the costs thereof, including, but not limited to, notices of non-responsibility, waivers of liens, surety company performance bonds and to protect Landlord and the Building against any loss from any mechanic’s, materialmen’s or other liens. Tenant shall pay in addition to any sums due pursuant to Article 4, any increase in real estate taxes attributable to any such alteration, addition or improvement for so long, during the Term, as such increase is ascertainable; at Landlord’s election said sums shall be paid in the same way as sums due under Article 4.

8.4 Tenant’s Property. Tenant must, at its sole cost, remove, upon termination of this Lease, any and all personal property, trade fixtures, furnishings, equipment, data and telecommunications cabling and wiring installed by or on behalf of Tenant and placed in the Premises by Tenant (the “Tenant’s Property”). Tenant shall, at its cost and expense, repair any damage to the Premises or the Building caused by such removal. Any of Tenant’s Property not removed from the Premises prior to the Expiration Date shall, at Landlord’s option, become the property of Landlord. Landlord may remove such Tenant’s Property, and Tenant shall pay to Landlord, Landlord’s cost of removal and of any repairs in connection therewith in accordance with Section 4.4 hereof.

8.5 Ownership and Removal. All additions, fixtures and improvements attached to or installed in or upon the Premises by Tenant or by Landlord shall be Landlord’s property and shall remain upon the Premises at the termination of this Lease without compensation, allowance or credit to Tenant. Landlord may require Tenant, at Tenant’s expense, to remove any of Tenant’s Property or Alterations which have been attached to or installed in the Premises unless Landlord consents to a written request from Tenant at the time of its approval of the Tenant’s plans that a building standard, non-specialty installation need not be so removed. If Tenant fails to remove any Tenant’s Property or Alterations that Tenant is required to remove pursuant to this Section 8.5 by the Expiration Date, or the sooner date of termination of this Lease then Landlord may remove the same and, Tenant shall pay to Landlord the cost of repairs of any damage to the Premises or Building in connection therewith. In lieu of requiring Tenant to remove such Tenant’s Property

21

and Alterations and repair the Premises as aforesaid, Landlord may, by written notice to Tenant delivered at least thirty (30) days before the Expiration Date, require Tenant to pay to Landlord, as Additional Rent hereunder, the cost of such removal and repair in an amount reasonably estimated by Landlord.

8.6 Surrender. Upon the expiration or sooner termination of the Term, Tenant will quietly and peacefully surrender to Landlord the Premises in as good condition as when Tenant took possession, ordinary wear and tear, condemnation and damage by fire or other casualty excepted, and otherwise as is required in Article 8. In addition, at such time Tenant shall remove all Hazardous Substances stored, or disposed of, or generated by Tenant in its use or operation of the Premises and all equipment and materials contaminated or affected by such Hazardous Substances in conformity with the Hazardous Substance laws.

8.7 Tenant’s Failure to Maintain. If Landlord gives Tenant written notice of the necessity of any repairs or replacements required to be made under Section 8.2 and Tenant fails to commence diligently to cure the same within twenty (20) days thereafter (except that no notice will be required in case of any emergency repair or replacement necessary to prevent substantial damage or deterioration), Landlord, at its option and in addition to any other remedies, may proceed to make such repairs or replacements and the expenses incurred by Landlord in connection therewith plus ten percent (10%) thereof for Landlord’s supervision, shall be due and payable from Tenant in accordance with Section 4.4 hereof, as Additional Rent; provided, that, Landlord’s making any such repairs or replacements shall not be deemed a waiver of Tenant’s default in failing to make the same.

ARTICLE 9. INSURANCE

9.1 Tenant’s Insurance. Tenant, at its own expense, shall provide and keep in force with companies which are rated A/XV or better by A.M. Best Company and licensed in the Commonwealth of Massachusetts: (a) combined single limit commercial general liability insurance insuring against liability for personal injury and property damage, including contractual liability, in the amount of $1,000,000.00 per occurrence/$1,000,000.00 annual aggregate limit; (b) “All Risk” or “Special Form” property insurance, including standard fire and extended coverage insurance, in amounts necessary to provide full replacement cost coverage, for Tenant’s Property, business personal property, machinery, electronic data and any Alterations in which Tenant has an insurable property interest, including, but not limited to, vandalism and malicious mischief and sprinkler leakage coverage, and, during any period that is conducted by Tenant at the Premises, “all risk” Builder’s Risk insurance, completed value, non-reporting form at any time that Tenant has commenced construction of any leasehold improvements or any Alterations; (c) business income insurance covering all risks required to be covered by the insurance provided in clause (b) above in an amount equal to 100% of the projected gross revenues from the operation of Tenant’s business for a period of at least twelve (12) months from the date of the casualty; (d) Workers’ Compensation Insurance in statutory limits as required by applicable law; and (e) any other insurance reasonably required by Landlord. At Landlord’s request, the amounts and kinds of insurance coverages described herein may be reasonably increased or expanded to reflect amounts and coverages then typically being carried for similar business operations in institutionally owned or financed properties.

Whenever Tenant shall undertake any alterations, additions or improvements in, to or about the Premises (“Work”) the aforesaid insurance protection must extend to and include injuries to persons and damage to property arising in connection with such Work, without limitation including liability under any applicable structural work act, and such other insurance as Landlord shall require; and the policies of or certificates evidencing such insurance must be delivered to Landlord prior to the commencement of any such Work.

9.2 Delivery of Policies. Each such insurance policy shall: (a) be provided in form, substance and amounts (where not above stated) reasonably satisfactory to Landlord and to Landlord’s Mortgagee; (b) specifically include the liability assumed hereunder by Tenant (provided that the amount of such insurance shall not be construed to limit the liability of Tenant hereunder); (c) shall provide that it is primary insurance, and not excess over or contributory with any other valid, existing and applicable insurance in force for or on behalf of Landlord; and (d) provide that Landlord shall receive thirty (30) days’ written notice from the insurer prior to any cancellation or material reduction of coverage (including material increases to deductibles). Tenant shall deliver policies of such insurance or certificates thereof to Landlord on or before

22

the Commencement Date, and thereafter at least thirty (30) days before the expiration dates of expiring policies. All such insurance certificates shall provide that Landlord, its mortgagees, any ground lessors and Landlord’s managing agent shall each be named as an additional insured. Tenant’s compliance with the provisions of this Article 9 shall in no way limit Tenant’s liability under any of the other provisions of this Lease.

9.3 Increased Insurance Risk. Tenant shall not do or permit anything to be done, or keep or permit anything to be kept in the Premises, which would: (a) be in violation of any governmental law, regulation or requirement, (b) invalidate or be in conflict with the provision of any fire or other insurance policies covering the Building or any property located therein, (c) result in a refusal by fire insurance companies of good standing to insure the Building or any such property in amounts required by Landlord’s Mortgagee (as hereinafter defined) or reasonably satisfactory to Landlord, (d) subject Landlord to any liability or responsibility for injury to any person or property by reason of any business operation being conducted in the Premises, or (e) cause any increase in the fire insurance rates applicable to the Property or property located therein at the beginning of the Term or at any time thereafter. In the event that any use of the Premises by Tenant increases such cost of insurance, Landlord shall give Tenant written notice of such increase and a reasonable opportunity to cure its use to prevent such increase; provided, however, if Tenant fails to do so, Tenant shall pay such increased cost to Landlord in accordance with Section 4.4 hereof. Acceptance of such payment shall not be construed as a consent by Landlord to Tenant’s such use, or limit Landlord’s remedies under this Lease.

9.4 Indemnity. Tenant shall defend with counsel reasonably acceptable to Landlord, indemnify and hold harmless Landlord, all employees, officers, directors, partners, members and shareholders of Landlord, Mortgagees of the Property and any other party having an interest therein from and against any and all liabilities, losses, damages, costs, expenses (including reasonable attorneys’ fees and expenses), causes of action, suits, claims, demands or judgments of any nature arising from or with respect to (a) any injury to or death of any person or damage to or loss of property in, on or about the Premises or the Property or connected with the use, condition or occupancy thereof by Tenant or any Tenant Party, (b) any breach or violation by Tenant of any of the terms, conditions or provisions of this Lease, (c) any act, omission, fault, willful misconduct, negligence or violation of applicable laws and regulations by Tenant or any Tenant Parties, (d) any construction or other work by Tenant on or about the Premises pursuant to Article 8 or otherwise; provided, however, Tenant’s indemnification obligations hereunder shall not apply to injury or damage to the extent arising from the negligence or willful act or omission of Landlord, or any of its officers, employees, agents or contractors.

9.5 Tenant’s Use and Occupancy. Tenant’s use and occupancy of the Premises and the Property and use by all Tenant Parties, and all Tenant’s and said parties’ furnishings, fixtures, equipment, improvements, materials, supplies, inventory, effects and property of every kind, nature and description which, during the continuance of this Lease or any occupancy of the Premises by Tenant or anyone claiming under Tenant, may be in, on or about the Premises, shall be at Tenant’s and said parties’ sole risk and hazard. Landlord shall not be liable to Tenant or any other party for injury to or death of any person or damage to or destruction of any property in, on or about the Premises, nor for any interruption in Tenant’s use of the Premises or the conduct of its business therein, nor for any other losses, damages, costs, expenses or liabilities whatsoever, including without limitation where caused by fire, water, explosion, collapse, the leakage or bursting of water, steam, or other pipes, any environmental or other condition in, on, or about the Premises, or any other event, occurrence, condition or cause. It is Tenant’s responsibility to maintain insurance against any such loss or casualty.

9.6 Waiver of Subrogation Rights.

9.6.1 Mutual Waiver. Landlord and Tenant hereby agree and hereby waive any and all rights of recovery against each other for loss or damage occurring to the Premises or the Property or any of Landlord’s or Tenant’s Property contained therein regardless of the cause of such loss or damage to the extent that the loss or damage is covered by the injured party’s insurance or the insurance the injured party is required to carry under this Lease, whichever is greater (without regard to any deductible provision in any policy). This waiver does not apply to claims caused by a party’s willful misconduct. This waiver also applies to each party’s directors, officers, employees, shareholders, and agents.

23

9.6.2 Insurance Policy Coverage. Each party will assure that its insurance permits waiver of liability and contains a waiver of subrogation. Each party shall secure an appropriate clause in, or an endorsement to, each insurance policy obtained by or required to be obtained by Landlord or Tenant, as the case may be, under this Lease, pursuant to which the insurance company: (a) waives any right of subrogation against Landlord or Tenant as the same may be applicable, or (b) permits Landlord or Tenant, prior to any loss to agree to waive any claim it might have against the other without invalidating the coverage under the insurance policy. If, at any time, the insurance carrier of either party refuses to write (and no other insurance carrier licensed in the Commonwealth of Massachusetts will write) insurance policies which consent to or permit such release of liability, then such party shall notify the other party and upon the giving of such notice, this Section shall be void and of no effect.

9.7 Landlord Indemnity. Landlord shall defend, indemnify and hold harmless Tenant and Tenant parties from and against any and all liabilities, losses, damages, costs, expenses (including reasonable attorneys’ fees and expenses), causes of action, suits, claims, demands or judgments of any nature arising from or with respect to: (a) any injury to or death of any person or damage to or loss of property in, on or about the Premises or Property arising out of or relating to the negligence or willful act or omission of Landlord, or any of its officers, employees, agents or contractors, or (b) any construction or other work performed by Landlord or any of its agents, contractors, employees, licensees or invitees at the Property; provided, however, Landlord’s obligations under this Section shall not apply to injury or damage to the extent caused by the negligence or willful act or omission of Tenant or Tenant Parties.

ARTICLE 10. CASUALTY

10.1 Damage or Destruction.

10.1.1 Landlord’s Repair Obligation. Tenant shall give prompt notice to Landlord of any damage by fire or other casualty (a “Casualty”) to the Premises or any portion thereof. During the thirty (30)-day period following the occurrence of a Casualty (the “Notice Period”), Landlord will notify Tenant of Landlord’s estimate of the period of time required to complete the restoration work. In the event that the Premises, or any part thereof, or access thereto, shall be so damaged or destroyed by fire or other insured Casualty that the Tenant shall not have reasonably convenient access to the Premises or any portion of the Premises shall thereby be otherwise rendered unfit for use and occupancy by the Tenant for the purposes set forth in Section 7.1, and if in the judgment of the Landlord the damage or destruction may be repaired within two hundred seventy (270) days with available insurance proceeds, then the Landlord shall so notify the Tenant and shall repair such damage or destruction as provided in Section 10.4 hereof with reasonable diligence, subject to the limitations, if any, of Laws. If in the judgment of the Landlord the Premises, or means of access thereto, cannot be repaired within two hundred seventy (270) days after the elapse of the Notice Period with available insurance proceeds, then either party shall have the right to terminate the term of this Lease by giving written notice of such termination to the other party within the period of thirty (30) to forty-five (45) days after the occurrence of the Casualty. If the reconstruction period estimated by Landlord is more than two hundred seventy (270) days and neither party terminates this Lease on account thereof, Landlord shall repair such damage or destruction as provided in Section 10.4 hereof with reasonable diligence subject to the limitations of any Laws and, in such case, the reconstruction period shall be the period so estimated by Landlord.

10.1.2 Failure to Complete Repairs; Rights of Termination. If Landlord is obligated, or elects to repair the damage to the Premises and fails to substantially complete the repairs within the period of time required or permitted by this Section 10.1 (as the same may be reasonably extended due to any delay caused by Force Majeure) (the “Reconstruction Period”), then the time for completion of repairs shall be extended by the period of such Force Majeure delay. Tenant shall have the right to terminate this Lease by delivery of written notice to Landlord not later than ten (10) days following the end of the Reconstruction Period.

24

10.2 Abatement of Rent. Annual Base Rent and Additional Rent shall not be abated or suspended if, following any Casualty, Tenant shall continue to have reasonably convenient access to the Premises and the Premises are not rendered unfit for use and occupancy. If Tenant shall not have reasonably convenient access to the Premises or any portion of the Premises shall be otherwise rendered unfit for use and occupancy by the Tenant for the purposes set forth in Section 7.1 by reason of such Casualty, then Rent shall be equitably suspended or abated relative to the portion of the Premises that cannot be used by Tenant for any of its business operations, effective as of the date of the Casualty until Landlord has (a) substantially completed the repair of the Premises and the means of access thereto, and (b) has delivered notice thereof to Tenant.

10.3 Events of Termination. Notwithstanding the provisions of this Article 10, if, prior to or during the Term the Building shall be so damaged by Casualty that, in Landlord’s reasonable estimate, the cost to repair the damage will be more than twenty-five percent (25%) of the replacement value of the Building immediately prior to the occurrence of the Casualty (whether or not the Premises shall have been damaged or rendered untenantable), then, in any of such events, Landlord, may give to Tenant, within ninety (90) days after such Casualty, a thirty (30) days’ notice of the termination of this Lease and, in the event such notice is given, this Lease and the term shall terminate upon the expiration of such thirty (30) days with the same effect as if such date were the Expiration Date. If more than twenty-five percent (25%) of the gross rentable area of the Premises shall be wholly or substantially damaged or destroyed by Casualty at any time during the last six (6) months of the Term, either Landlord or Tenant may terminate this Lease by delivery of written notice of such termination to the other party within thirty (30) days after the occurrence of such damage.

10.4 Scope of Landlord’s Repairs. In the event Landlord elects or shall be obligated to repair or restore any damage or destruction to the Premises pursuant to this Article 10, Landlord shall not be obligated to restore or replace Tenant’s Property or Tenant’s Alterations or reconstruct Tenant’s initial tenant installations except the building standard improvements constructed by Landlord. No damages, compensation or claim shall be payable by the Landlord to Tenant, or any other person, by reason of inconvenience, loss of business or annoyance arising from any damage or destruction, or any repair thereof, as is referred to in this Article 10.

ARTICLE 11. CONDEMNATION

11.1 Entire Condemnation. In the event that the whole of the Premises shall be taken under the power of eminent domain or by any proceeding for taking for public or quasi-public use (a “Condemnation”), this Lease and the term and estate hereby granted shall automatically terminate as of the earlier of the date of the vesting of title or the date of dispossession of Tenant as a result of such taking.

11.2 Partial Condemnation.

11.2.1 Effect of Partial Condemnation. In the event that only a part of the Premises shall be taken by Condemnation and the remaining Premises are suitable for general office use without material interference with Tenant’s business operations and Tenant shall have reasonable, convenient access to and from the Premises, the Term shall expire as to that portion of the Premises condemned effective as of the date of the vesting of title in the condemning authority, and this Lease shall continue in full force and effect as to the part of the Premises not so taken. In the event of a partial Condemnation of the Premises which results in a lack of reasonable, convenient access to and from the Premises or which results in insufficient space for Tenant to carry on its business without material interference with its business, Tenant shall have the right to terminate this Lease if Landlord cannot relocate Tenant to comparable space elsewhere in the Building following the effective date of the Condemnation.

11.2.2 Landlord’s Option to Terminate. In the event that a part of the Property shall be subject to Condemnation (whether or not the Premises are affected), Landlord may, at its option, terminate this Lease as of the date of such vesting of title, by notifying Tenant in writing of such termination within

25

ninety (90) days following the date on which Landlord shall have received notice of the vesting of title in the condemning authority if in Landlord’s reasonable opinion: (a) a substantial alteration or reconstruction of the Property (or any portion thereof) shall be necessary or appropriate, or (b) the portion of the Property so condemned has the effect of rendering the remainder of the Property uneconomic to maintain.

11.2.3 Landlord’s Repair Obligations. In the event that this Lease is not terminated in accordance with Subsection 11.2.2 hereof, Landlord shall, upon receipt of the award in condemnation, make all necessary repairs or alterations to the Building in which the Premises are located so as to constitute the remaining Premises a complete architectural unit to the extent feasible and permitted by applicable law, but Landlord shall not be required to spend for such work an amount in excess of the amount received by Landlord as damages for the part of the Premises so taken. “Amount received by Landlord” shall mean that part of the award in condemnation which is free and clear to Landlord of any collection by Mortgagees and after payment of all costs involved in collection, including but not limited to attorney’s fees. Tenant, at its own cost and expense shall, restore its exterior signs (excluding the signage provided by Landlord under Section 7.7 above), trade fixtures, equipment, furniture, furnishings and other installations of personalty of Tenant which are not taken to as near its former condition as the circumstances will permit. In the event of a partial taking, all provisions of this Lease shall remain in full force and effect.

11.3 Temporary Taking. If there is a taking of the Premises for temporary use arising out of a temporary emergency or other temporary situation, this Lease shall continue in full force and effect, and Tenant shall continue to comply with Tenant’s obligations under this Lease, except to the extent compliance shall be rendered impossible or impracticable by reason of the taking, and Tenant shall be entitled to the award for its leasehold interest.

11.4 Condemnation Awards. Except as provided in the preceding Section 11.3, Landlord shall be entitled to the entire award in any condemnation proceeding or other proceeding for taking for public or quasi-public use, including, without limitation, any award made for the value of the leasehold estate created by this Lease. No award for any partial or entire taking shall be apportioned, and Tenant hereby assigns to Landlord any award that may be made in such condemnation or other taking, together with any and all rights of Tenant now or hereafter arising in or to same or any part thereof; provided, however, that nothing contained herein shall be deemed to give Landlord any interest in or to require Tenant to assign to Landlord any award made to Tenant specifically for its relocation expenses or the taking of Tenant’s Property provided that such award does not diminish or reduce the amount of the award payable to Landlord.

11.5 Proration. In the event of a partial condemnation or other taking that does not result in a termination of this Lease as to the entire Premises, then the Annual Base Rent and Tenant’s Share shall be adjusted in proportion to that portion of the Premises taken by such condemnation or other taking.

ARTICLE 12. ASSIGNMENT AND SUBLETTING

12.1 Transfers.

12.1.1 Landlord’s Consent. Subject to operation of Section 12.1.5 and 12.1.6 below, Tenant shall not, without the prior written consent of Landlord, which consent shall not be unreasonably withheld, conditioned or delayed as further described below: (a) except in connection with a mortgage or collateral assignment to a bona fide third party lender, assign or otherwise transfer this Lease or its direct interest herein, whether by operation of law or otherwise, (b) sublet the Premises or any part thereof, or (c) permit the use of the Premises by any Persons other than Tenant and its employees, invitees, guests and agents. The foregoing restricted actions are referred to herein collectively as “Transfers” and any Person to whom any Transfer is made or sought to be made is hereinafter sometimes referred to as a “Transferee”.    As used in this Lease, the term “Person” means an individual, trust, partnership, limited liability company, joint venture, association, corporation and any other entity. Tenant agrees to reimburse Landlord upon written demand for legal fees and any other reasonable expenses and costs incurred by Landlord in connection with any proposed assignment or subletting or other Transfer.

12.1.2 Certain Transfers. For purposes of this Lease, the term “Transfer” shall also include, and all of the foregoing provisions shall apply to (a) the dissolution of Tenant, or (b) the sale or other

26

transfer of more than an aggregate of 50% of Tenant’s net assets to the extent that, upon the consummation of such transaction, Tenant’s net worth is materially adversely impaired relative to its net worth immediately prior to the consummation of such transaction.

12.1.3 Transfer Notice. If Tenant shall desire to effect any Transfer requiring Landlord’s consent hereunder, Tenant shall notify Landlord in writing, which notice (a “Transfer Notice”) shall include: (a) the proposed effective date (which shall not be less than thirty (30) nor more than 180 days after Tenant’s notice), (b) the portion of the Premises to be Transferred (herein called the “Subject Space”), (c) the terms of the proposed Transfer and the consideration therefor, the name, address and background information concerning the proposed Transferee, and a true and complete copy of all proposed Transfer documentation, and (d) financial statements (balance sheets and income/expense statements for the current and prior three (3) years) of the proposed Transferee, in form and detail reasonably satisfactory to Landlord, certified by an officer, partner or owner of the Transferee, and any other information to enable Landlord to determine the financial condition, credit, character, and reputation of the proposed Transferee, nature of such Transferee’s business and proposed use of the Subject Space, and such other information as Landlord may reasonably require. Landlord shall respond to Tenant’s notice of a proposed Transfer within thirty (30) days following Tenant’s submission to Landlord of completed notice therefor in compliance with the foregoing provisions of this Section 12.1). Any Transfer made without complying with this Article shall at Landlord’s option be null, void and of no effect, or shall constitute an Event of Default under this Lease.

12.1.4 Approval. The parties hereby agree that it shall be reasonable under this Lease and under any applicable Law for Landlord to withhold consent to any proposed Transfer where one or more of the following applies (without limitation as to other reasonable grounds for withholding consent): (a) the Transferee is of a character or reputation or engaged in a business which is not consistent with the quality or nature of the Premises or the Property, or would be a significantly less prestigious occupant of the Premises than Tenant, (b) the Transferee intends to use the Subject Space for purposes which are not permitted under this Lease, (c) the Subject Space is not regular in shape with appropriate means of ingress and egress suitable for normal renting purposes, would result in more than a reasonable number of occupants, or would require increased services by Landlord, (d) the Transferee is a government (or agency or instrumentality thereof), (e) the proposed Transferee does not have, in Landlord’s sole good faith determination, satisfactory references or a reasonable financial condition in relation to the obligations to be assumed in connection with the Transfer, (f) the proposed Transfer involves conversion, merger or consolidation of Tenant into a limited liability company or limited liability partnership which would have the legal effect of releasing Tenant from any obligations under this Lease, (g) the proposed Transfer would cause Landlord to be in violation of any applicable Laws or any other lease, Mortgage or agreement to which Landlord is a party, or would create adverse tax consequences for Landlord, or (h) Tenant has committed and failed to cure a an Event of Default.

12.1.5 Permitted Assignments. Notwithstanding the foregoing or anything contained herein, Landlord’s consent to an assignment or transfer of this Lease (whether directly or indirectly), 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.    In addition, to the extent otherwise prohibited by this Lease, 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) the net worth (as determined in accordance with GAAP) of the assignee is not less than the greater of the net worth (as determined in accordance with GAAP) of Tenant immediately prior to the effectiveness of such assignment or transfer, and (ii) 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.” For any Transfer that is effected as a Permitted Assignment without Landlord’s consent, Tenant shall provide Landlord with a Transfer Notice substantiating the basis for such Permitted Assignment. Tenant shall pay all costs reasonably incurred by Landlord in connection with any such Permitted Assignments, including attorney’s fees.

27

12.1.6 Change in Control. Notwithstanding anything to the contrary contained herein, the term “Transfer” shall exclude (and no consent of Landlord shall be required for) any change in control of Tenant resulting from Tenant obtaining financing from investors which invest in private companies or undergoing a public offering which results in a change in control of Tenant (including venture capital and/or private equity funding and/or funding from corporate partners), lenders, or other debt, equity, or other financing providers; provided that (i) in no event shall such financing result in a change in use of the Premises as permitted in this Lease, and (ii) Tenant shall pay all costs reasonably incurred by Landlord in connection with its review of such transactions and change in control, including attorney’s fees.

12.2 Landlord’s Options; Recapture. Excluding Permitted Assignments pursuant to Section 12.1.5 above, those Transfers expressly permitted above, and any sublease for a duration of less than substantially all of the remaining Term of the Lease or for less than substantially all of the Premises, Landlord shall have the option, exercisable by written notice delivered to Tenant within thirty (30) days after Landlord’s receipt of a Transfer Notice accompanied by the other information described in Section 12.1, to: (a) permit or disapprove the Transfer in accordance with the requirements above; or (b) recapture the Subject Space, and in the case of a Transfer affecting less than all of the Premises, amend this Lease to terminate the same with respect to the Subject Space (the “Recaptured Portion”). If Landlord approves of the proposed Transfer as set forth above, Tenant may enter into the proposed Transfer with such proposed Transferee subject to the following conditions: (i) the Transfer shall be on the same terms set forth in the Transfer Notice, and (ii) no Transfer shall be valid and no Transferee shall take possession of the Premises until an executed counterpart of the assignment, sublease or other instrument effecting the Transfer (in the form approved by Landlord) has been delivered to Landlord pursuant to which the Transferee shall expressly assume all of Tenant’s obligations under this Lease.

If Tenant has requested to Transfer the entirety of the Premises and Landlord’s notice provides for the recapture of the entire Premises, then this Lease shall be deemed terminated effective as of the date stated in Tenant’s notice as the effective date of Tenant’s proposed Transfer and, upon the request of either party, the parties shall execute written confirmation of the same. If, however, Tenant has requested to Transfer only a portion of the Premises and Landlord’s notice shall provide for the recapture of only the Recaptured Portion, then (A) this Lease shall be deemed amended so as to terminate this Lease as to the Recaptured Portion effective as of the date stated in Tenant’s notice as the effective date of Tenant’s proposed Transfer, (B) notwithstanding anything in this Lease to the contrary, the Rent herein (and Tenant’s parking allocation) shall be prorated on the basis of the number of rentable square feet retained by Tenant following the recapture in proportion to the number of rentable square feet contained in the Premises prior to the recapture, (C) this Lease as so amended shall continue thereafter in full force and effect, and (D) upon request of either party the parties shall execute written confirmation of the same. Tenant shall surrender and vacate the entire Premises or the Recaptured Portion, as applicable, when required hereunder in accordance with Section 8.6 and any failure to do so shall be subject to Section 2.2, provided, that, in the case of Landlord’s recapture of a Recaptured Portion, Tenant shall be responsible for the payment and performance of the alterations necessary to segregate the Recaptured Portion from the balance of the Premises in compliance with applicable building codes, including construction of a demising wall and adequate separation of building HVAC and utility systems from the remaining Tenant space in accordance with applicable Laws.

12.3 Terms of Consent. If Landlord consents to a Transfer: (a) the terms and conditions of this Lease, including Tenant’s primary liability for the Subject Space, shall in no way be deemed to have been waived or modified, (b) such consent shall not be deemed consent to any further Transfer by either Tenant or a Transferee, (c) no Transferee shall succeed to any rights provided in this Lease or any amendment hereto to terminate this Lease (in whole or in part), to extend the Term of this Lease, to expand the Premises, or to lease other space, any such rights being deemed personal to the initial Tenant, (d) Tenant shall deliver to Landlord promptly after execution, an original executed copy of all documentation pertaining to the Transfer in form reasonably acceptable to Landlord, and (e) Tenant shall furnish a complete statement, certified by an independent certified public accountant, or Tenant’s chief financial officer (or the person serving in the most comparable role), setting forth in detail the computation of any “Transfer Profit” (as defined below) that Tenant has derived and shall derive from such Transfer. Landlord or its authorized representatives shall have the right at all reasonable times to audit the books, records and papers of Tenant and any Transferee

28

relating to any Transfer, and shall have the right to make copies thereof. If the Transfer Profit respecting any Transfer shall be found understated, Tenant shall within thirty (30) days after demand pay the deficiency, and if understated by more than two percent (2%) Tenant shall pay Landlord’s costs of such audit. Any sublease hereunder shall be subordinate and subject to the provisions of this Lease, and if this Lease shall be terminated during the term of any sublease, Landlord shall have the right to: (i) deem such sublease as merged and canceled and repossess the Subject Space by any lawful means, or (ii) deem such termination as an assignment of such sublease to Landlord and not as a merger, and require that such subtenant attorn to and recognize Landlord as its landlord under any such sublease. If an Event of Default occurs under this Lease, Landlord is hereby irrevocably authorized, as Tenant’s agent and attorney-in fact, to direct any Transferee to make all payments under or in connection with the Transfer directly to Landlord (which Landlord shall apply towards Tenant’s obligations under this Lease).

12.4 No Release. Unless expressly stated to the contrary therein, Landlord’s consent to a Transfer shall not release Tenant of Tenant’s obligations under this Lease and this Lease and all of the obligations of Tenant under this Lease shall continue in full force and effect as the obligations of a principal (and not as the obligations of a guarantor or surety). No acceptance of Rent by Landlord from or recognition in any way of the occupancy of the Premises by a Transferee shall be deemed a consent to such Transfer, or a release of Tenant from direct and primary liability for the further performance of Tenant’s covenants hereunder. The consent by Landlord to a particular Transfer shall not relieve Tenant from the requirement of obtaining the consent of Landlord to any further Transfer. Each violation of any of the covenants, agreements, terms or conditions of this Lease, whether by act or omission, by any of Tenant’s permitted Transferees, shall constitute a violation thereof by Tenant. In the event of default by any Transferee of Tenant or any successor of Tenant in the performance of any of the terms hereof, to the extent Tenant has not been released therefrom, Landlord may proceed directly against Tenant without the necessity of exhausting remedies against such Transferee or successor.

12.5 Additional Conditions. Tenant shall not offer to make, or enter into negotiations with respect to any Transfer to: (a) any tenant of the Building (or any affiliate of such tenant) that is a tenant in the Building unless there is no competing space then available for leases therein; (b) any bona fide prospective tenant to whom Landlord has submitted a leasing proposal or with whom Landlord is then negotiating with respect to other space in the Building; or (c) any party which would be of such type, character, or condition as to be inappropriate as a tenant for the Building. Upon delivery of written notice by Landlord to Tenant that Tenant is engaging in any such prohibited activity, Tenant shall cease such prohibited actions. It shall not be unreasonable for Landlord to disapprove any proposed Transfer to any of the foregoing entities. Landlord shall not be deemed to unreasonably withhold its consent to any proposed assignment or sublease if such Transfer, in Landlord’s reasonable determination, is at a full-service rate which is less than Landlord’s current rate in the Building for new tenants, and would compete with similar space either being offered by Landlord in the Building.

12.6 Transfer Profit. If Landlord consents to a Transfer, as a condition thereto, which the parties hereby agree is reasonable, Tenant shall pay to Landlord, as Additional Rent, one half (1/2) of any Transfer Profit collected by Tenant from such Transfer. “Transfer Profit” shall mean for a lease assignment, all consideration paid or payable therefor. “Transfer Profit” shall mean, for a sublease, all rent, additional rent or other consideration paid by such Transferee in excess of the Rent payable by Tenant under this Lease (on a monthly basis during the Term, and on a per rentable square foot basis, if less than all of the Premises is transferred). Transfer Profit shall also include any bonus amount paid by Transferee to Tenant, and any payment in excess of the fair market value for services rendered by Tenant to Transferee or in excess of Tenant’s depreciated tax basis for assets, fixtures, inventory, equipment or furniture transferred by Tenant to Transferee. In determining Transfer Profit, Tenant shall be permitted to deduct any “free rent”, tenant improvement costs, and reasonable legal and brokerage costs actually paid by Tenant to third parties unaffiliated with Tenant in connection with the particular Transfer, which costs shall have been documented to Landlord’s reasonable satisfaction (which costs shall be amortized on a straight-line basis over the term of the Transfer). Tenant shall pay such portion of the Transfer Profit to Landlord on a monthly basis within ten (10) days after receipt thereof, without affecting or reducing any other obligations of Tenant hereunder. Tenant shall send each such payment with a detailed statement. Landlord shall have the right to audit Tenant’s books and records to verify the accuracy of Tenant’s statement.

29

ARTICLE 13. DEFAULTS AND REMEDIES

13.1 Events of Default. The occurrence of any one or more of the following events shall constitute an event of default (each an “Event of Default”) hereunder:

13.1.1 Nonpayment of Annual Base Rent or Additional Rent. Tenant shall fail to pay any installment of Annual Base Rent or the Additional Rent payable under Article 5 hereof, upon the date when said payment is due; provided, however, Landlord shall furnish Tenant with written notice of such failure and permit Tenant a five (5)-day period to cure such failure.

13.1.2 Other Lease Payments. Except with respect to those payments identified in Section 13.1 above, Tenant shall fail to pay any other amount, deposit, reimbursement or sum, due and payable hereunder within thirty (30) days following Landlord’s delivery of its invoice therefor.

13.1.3 Certain Obligations. Tenant shall fail to perform, observe or comply with any of the covenants, agreements or obligations contained in Section 4.6 (“Security Deposit”), Section 7.5 (“No Liens”), Section 9.2 (“Delivery of Policies”), Article 12 (“Assignment and Subletting”) or Article 14 (“Subordination, Attornment; and Rights of Mortgage Holders”) of this Lease within the time periods set forth therein.

13.1.4 Other Obligations. Tenant shall fail to perform any covenant, agreement or obligation under this Lease other than those matters specified in Section 13.1.1 and 13.1.2, and such failure continues for thirty (30) days after written notice by Landlord to Tenant of such failure; provided, however, that if the nature of Tenant’s obligation is such that more than thirty (30) days are required for performance, then Tenant shall not be in default if Tenant commences performance within such thirty (30)-day period and thereafter diligently and continuously prosecutes the same to completion within ninety (90) days following the date of Landlord’s written notice with respect to such failure.

13.1.5 Assignment; Receivership; Attachment. Tenant shall make any arrangement or general assignment for the benefit of creditors; or a receiver, trustee or liquidator shall be appointed for Tenant or for any substantial part of its assets, or properties, or Tenant’s interest in this Lease; or there shall be an attachment, execution, or other judicial seizure of substantially all of Tenant’s assets located at the Premises or of Tenant’s interest in this Lease.

13.1.6 Bankruptcy. The admission by Tenant or Tenant’s guarantor (if any) in writing of its inability to pay its debts as they become due; Tenant or Tenant’s guarantor (if any) shall file a petition in bankruptcy seeking any reorganization, arrangement, composition, readjustment, liquidation, dissolution or similar relief under any present or future statute, law or regulation; the filing of a petition in bankruptcy against Tenant or Tenant’s guarantor (if any) seeking any involuntary reorganization, or arrangement, composition, readjustment, liquidation, dissolution or similar relief under any present or future statute, law or regulation by any of Tenant’s creditors or such guarantor’s creditors, and such petition shall not have been vacated within thirty (30) days; or Tenant shall be adjudicated bankrupt or insolvent under any present or future statute, law, regulation, under state or federal law, and such judgment or decree is not vacated or set aside within thirty (30) days.

13.2 Remedies. If an Event of Default occurs, Landlord shall have the following rights and remedies, in addition to any and all other rights or remedies available to Landlord in law or equity:

13.2.1 Notice to Quit. Landlord shall have the right to deliver written notice to Tenant to quit possession and occupancy of the Premises and to declare the Lease terminated. Upon Landlord’s termination of this Lease, Tenant shall quit and peaceably surrender the Premises, and all portions thereof, to Landlord, and Landlord shall have the right to receive all rental and other income of and from the same.

13.2.2 Right of Re-Entry. Landlord shall have the right, with or without terminating this Lease, to re-enter the Premises and take possession thereof by summary proceeding, eviction, ejectment or

30

otherwise and may dispossess all other persons and property from the Premises. Tenant’s property may be removed and stored in a public warehouse or elsewhere at the cost of and for the account of Tenant. No re-entry or taking possession of the Premises by Landlord pursuant to this Subsection 13.2.2 shall be construed as an election to terminate this Lease unless a written notice of such intention is given to Tenant or unless the termination thereof is decreed by a court of competent jurisdiction. Tenant thereby waives all statutory rights, including without limitation the right to a notice to quit, notice before exercise of any prejudgment remedy, and any rights of redemption, all to the extent such rights may be lawfully waived.

13.2.3 Recovery of Rent and Damages. Landlord shall have the right to recover from Tenant all loss of Rent and other payments that Landlord may incur by reason of termination of the Lease, including, without limitation: (a) all Rent and other sums due and payable by Tenant as of the date of termination; (b) all Rent that would otherwise be payable for the remainder of the Term in accordance with the terms of this Lease; (c) the costs of collecting amounts due from Tenant under the Lease and the costs of recovering possession of the Premises (including attorney’s fees and litigation costs); and (d) all Landlord’s other direct damages and reasonable expenditures arising from the termination of the Lease. Tenant shall reimburse Landlord for all such items, and the same shall be due and payable immediately from time to time upon notice from Landlord that an expense has been incurred, without regard to whether the expense was incurred before or after the termination.

13.2.4 Acceleration of Future Rentals. Following termination of this Lease, Landlord, at its election, may demand to be indemnified for its loss of Rent (with respect to the period following such termination) by a lump sum payment representing the then present value of the amount of Rent that would have been paid in accordance with this Lease for the remainder of the Term minus the then present value of the aggregate fair market rent and additional charges payable for the Premises for the remainder of the Term (if less than the Rent payable hereunder) estimated as of the date of termination, and taking into account Landlord’s reasonable projections of vacancy and time required to re-lease the Premises. Landlord shall be entitled to recover from Tenant, and Tenant shall pay to Landlord, on demand, such amount as final damages for Tenant’s default with respect to the Rents payable for the remainder of the Term as described above. In the computation of present value, the Federal Reserve discount rate (or equivalent) shall be employed.

13.2.5 Rents Due After Re-Entry by Landlord. If Landlord re-enters or otherwise takes possession of the Premises without terminating this Lease (but terminating only Tenant’s right of possession in the Premises), then the Lease and Tenant’s liabilities and obligations thereunder shall survive such action. In the event of any such termination of Tenant’s right of possession, whether or not the Premises, or any portion thereof, shall have been relet, Tenant shall pay the Landlord a sum equal to the Rent and any other charges required to be paid by Tenant up to the time of such termination of such right of possession and thereafter Tenant, until the end of the Term, shall be liable to Landlord for and shall pay to Landlord: (a) the equivalent of the amount of the Rent payable under this Lease, less (b) the net proceeds of any reletting effected pursuant to the provisions hereof after deducting all of Landlord’s Reletting Expenses. Tenant shall pay such amounts in accordance with the terms of this Subsection 13.2.5 as set forth in a written statement thereof from Landlord to Tenant (the “Deficiency”) to Landlord in monthly installments on the days on which the Annual Base Rent is payable under this Lease, and Landlord shall be entitled to recover from Tenant each monthly installment of the Deficiency as the same shall arise. Tenant shall also pay to Landlord upon demand the costs incurred by Landlord in curing Tenant’s defaults existing at or prior to the date of such termination, the cost of recovering possession of the Premises and the Reletting Expenses. Tenant agrees that Landlord may file suit to recover any sums that become due under the terms of this Section from time to time, and all reasonable costs and expenses of Landlord, including attorneys’ fees and costs incurred in connection with such suits shall be payable by Tenant on demand.

13.2.6 Certain Terms Defined. For purposes of this Subsection 13.2.6, “Reletting Alterations” shall mean all repairs, changes, improvements, alterations or additions made by Landlord in or to the Premises to the extent deemed reasonably necessary by Landlord to prepare the Premises for the re-leasing following an Event of Default; and “Reletting Expenses” shall mean the reasonable expenses paid or incurred by Landlord in connection with any re-leasing of the Premises following an Event of Default, including, without limitation, marketing expenses, brokerage commissions, attorneys’ fees, the costs of Reletting Alterations, tenant allowances and other economic concessions provided to the new tenant.

31

13.3 Landlord’s Right to Cure Defaults. If an Event of Default occurs or Landlord reasonably determines that an emergency exists following Tenant’s failure to perform or comply with any of its obligations under this Lease, the Landlord, without being under any obligation to do so and without thereby waiving such default, may remedy such default for the account and at the reasonable expense of the Tenant. If the Landlord makes any expenditures or incurs any obligations for the payment of money in connection therewith, including but not limited to reasonable attorney’s fees in instituting, prosecuting or defending any action or proceeding, such sums paid or obligation incurred and costs, shall be paid upon demand to the Landlord by the Tenant as Additional Rent pursuant to Section 4.4 hereof and if not so paid with interest from its due date until paid at the lesser of eighteen percent (18%) per annum or the maximum legal rate that Landlord may charge Tenant.

13.4 Disposition of Tenant’s Property. In addition to Landlord’s rights under Section 8.4 hereof, Landlord shall have the right to handle, remove, discard or store in a commercial warehouse or otherwise, at Tenant’s sole risk and expense, any of Tenant’s Property that is not removed by Tenant at the end of the Term. Landlord shall in no event be responsible for the value, preservation or safekeeping thereof. Tenant shall pay to Landlord, upon demand, any and all expenses incurred in such removal and all storage charges for such property so long as the same shall be in Landlord’s possession or under Landlord’s control.

13.5 Reletting; Mitigation of Damages. In connection with any reletting of the Premises following an Event of Default, Landlord shall be entitled to grant such rental and economic concessions and other incentives as may be customary for similar space in Middlesex County, Massachusetts. Landlord shall not be required to accept any tenant offered by Tenant or observe any instruction given by Tenant about such reletting or do any act or exercise any care or diligence with respect to such reletting; provided, however, that notwithstanding anything in this Lease to the contrary, in connection with any reletting or Landlord’s exercise of any other rights or remedies permitted hereunder, Landlord shall use reasonable efforts to mitigate its damages.

13.6 No Accord and Satisfaction. Landlord may collect and receive any rent due from Tenant, and the payment thereof shall not constitute a waiver of or affect any notice or demand given, suit instituted or judgment obtained by Landlord, or be held to waive, affect, change, modify or alter the rights or remedies that Landlord has against Tenant in equity, at law, or by virtue of this Lease. No receipt or acceptance by Landlord from Tenant of less than the monthly rent herein stipulated shall be deemed to be other than a partial payment on account for any due and unpaid stipulated rent; no endorsement or statement on any check or any letter or other writing accompanying any check or payment of rent to Landlord shall be deemed an accord and satisfaction, and Landlord may accept and negotiate such check or payment without prejudice to Landlord’s rights to (a) recover the remaining balance of such unpaid rent, or (b) pursue any other remedy provided in this Lease.

13.7 Tenant’s Bankruptcy.

13.7.1 Insolvency. If at any time and for so long as Tenant shall be subjected to the provisions of the United States Bankruptcy Code or other law of the United States or any state thereof for the protection of debtors as in effect at such time (each a “Bankruptcy Law”), Tenant, Tenant as debtor-in-possession, and any trustee or received of Tenant’s assets (each a “Tenant’s Representative”) shall have no greater right to assume or assign this Lease or any interest in this Lease, or to sublease any of the Premises than accorded to Tenant in Article 12, except to the extent Landlord shall be required to permit such assumption, assignment or sublease by the provisions of such Bankruptcy Law. Without limitation of the generality of the foregoing, any right of any Tenant’s Representative to assume or assign this Lease or to sublease any of the Premises shall be subject to the conditions that:

(a) Such Bankruptcy Law shall provide to Tenant’s Representative a right of assumption of this Lease which Tenant’s Representative shall have timely exercised and Tenant’s Representative shall have fully cured any default of Tenant under this Lease;

(b) Tenant’s Representative or the proposed assignee, as the case shall be, shall have deposited with Landlord as security for the timely payment of rent an amount equal to the larger of: (a) three (3) months’ Rent and other monetary charges accruing under this Lease; and (b) any sum

32

specified in Section 4.6; and shall have provided Landlord with adequate other assurances of the future performance of the obligations of the Tenant under this Lease. Without limitation, such assurances shall include, at least, in the case of assumption of the Lease, demonstration to the satisfaction of the Landlord that Tenant’s Representative has and will continue to have sufficient unencumbered assets after the payment of all secured obligations and administrative expenses to assure Landlord that Tenant’s Representative will have sufficient funds to fulfill the obligations of Tenant under this Lease; and, in the case of assignment, submission of current financial statements of the proposed assignee, audited by an independent certified public accountant reasonably acceptable to Landlord and showing a net worth, liquid assets and working capital in amounts determined by Landlord to be sufficient to assure the future performance by such assignee of all of the Tenant’s obligations under this Lease;

(c) The assumption or any contemplated assignment of this Lease or subleasing of any part of the Premises, as shall be the case, will not breach any provisions in any other lease, mortgage, financing agreement or other agreement by which Landlord is bound;

(d) Landlord shall have, or would have had absent the Bankruptcy Law, no right under Article 12 to refuse consent to the proposed assignment or sublease by reason of the identity or nature of the proposed assignee or sublessee or the proposed use of the Premises concerned.

13.7.2 No Limitation on Claim. Nothing herein shall limit or prejudice the right of Landlord to prove and obtain in proceeding for bankruptcy, insolvency, arrangement or reorganization by reason of the termination of this Lease, an amount equal to the maximum allowed by any statute or rule of law in effect at the time when, and governing the proceedings in which, the damages are to be proved, whether or not the amount is greater, equal to or less than the amount of the loss or damage that Landlord has suffered.

13.8 Arbitration. Any dispute arising out of or relating to Article 5 of this Lease (with respect to the issues expressly stated therein) shall be submitted to and determined in binding arbitration under the Commercial Arbitration Rules of the American Arbitration Association. The arbitration shall be conducted before and by a single arbitrator selected by the parties who shall have a minimum of ten (10) years of experience in commercial real estate disputes and who shall not be affiliated with either Landlord or Tenant. If the parties have not selected an arbitrator within thirty (30) days of written demand for arbitration, the arbitrator shall be selected by the American Arbitration Association pursuant to the then current rules of that Association on application by either party. The arbitrator shall have authority to fashion such just, equitable and legal relief as such arbitrator, in such arbitrator’s sole discretion, may determine; provided, however, the arbitrator shall not be authorized to award consequential, special, indirect or punitive damages. The parties agree that the arbitration hearing shall be held within thirty (30) business days following notification to the parties of the appointment of such arbitrator, and that the arbitration proceedings shall be concluded within thirty (30) business days following the first scheduled arbitration hearing. At the arbitration hearing each party shall present its position (including the right to present witness testimony) and rebuttal within the time period established by the arbitrator (which shall be the same for both parties). Each party shall bear all its own expenses of arbitration and shall bear equally the costs and expenses of the arbitrator. All arbitration proceedings shall be conducted in the City of Boston, Commonwealth of Massachusetts. The arbitrator’s decision shall be final and binding on the parties. Landlord and Tenant further agree that they will faithfully observe this Lease and rules, and that they will abide by and perform any award rendered by the arbitrator and that a judgment of the court having jurisdiction may be entered upon the award. The duty to arbitrate shall survive the cancellation or termination of this Lease.

13.9 WAIVER OF TRIAL BY JURY. TO THE EXTENT PERMITTED BY APPLICABLE LAW, LANDLORD AND TENANT HEREBY WAIVE THE RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM, WHETHER IN CONTRACT, TORT OR OTHERWISE, BROUGHT BY EITHER AGAINST THE OTHER ON ANY MATTER WHATSOEVER ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS LEASE, THE RELATIONSHIP OF LANDLORD AND TENANT, OR TENANT’S USE OR OCCUPANCY OF THE PREMISES, OR ANY SUMMARY PROCESS, EVICTION OR OTHER STATUTORY REMEDY WITH RESPECT THERETO. EACH PARTY HAS BEEN REPRESENTED BY, AND HAS RECEIVED THE ADVICE OF, LEGAL COUNSEL WITH RESPECT TO THIS WAIVER.

ARTICLE 14. SUBORDINATION; ATTORNMENT; AND RIGHTS OF MORTGAGE HOLDERS

14.1 Subordination; Attornment.

14.1.1 Subordination. Tenant acknowledges that Landlord is now, or may be in the future, a tenant under a lease of the Land and/or entire Property of which the Premises forms a part. This Lease is and shall be, at Landlord’s option, subject and subordinate to all ground or underlying leases (each, a “Superior Lease”) and to all mortgages, deeds of trust or liens resulting from any other method of financing or refinancing which now or hereafter affects such leases or the real property of which the Premises forms a part and to all renewals, modifications, consolidations, replacements and extensions thereof (each, a “Mortgage”). The holder of a Mortgage is sometimes referred to herein as a “Mortgagee”. This Section shall be self-operative and no further instrument of subordination shall be necessary. In confirmation of such subordination, Tenant shall execute promptly any certificate that Landlord may reasonably request.

14.1.2 Attornment. In the event that any Superior Lease is terminated, or any Mortgage is foreclosed or title transferred as a result of a deed-in-lieu of foreclosure, this Lease shall not terminate or be terminable by Tenant unless Tenant is specifically named in any termination or foreclosure judgment or final order, and Tenant shall attorn to any such successor lessor and recognize such lessor as Landlord under this Lease. In the event of a sale or assignment of Landlord’s interest in the Property of which the Premises forms a part, Tenant shall attorn to the purchaser and recognize such purchaser as Landlord under this Lease. In the event that any Mortgagee shall succeed to the interest of Landlord, whether by judicial or non-judicial foreclosure or otherwise, at the election of such Mortgagee, Tenant shall attorn to any such successor landlord and recognize such landlord as Landlord under this Lease and Tenant shall promptly execute and deliver any instrument that such Mortgagee may reasonably request to evidence such attornment. In the event that any Superior Lease is terminated or any Mortgage is foreclosed or the Property is transferred by deed-in-lieu of foreclosure, Tenant agrees, at Landlord’s, master landlord’s, trustee’s or Mortgagee’s option, to enter into a new lease covering the Premises for the remaining Term and otherwise on the same terms, conditions and rentals as herein contained.

14.1.3 Rights of Mortgagees. Notwithstanding anything contained in this Lease to the contrary, if any Mortgagee elects to have this Lease made superior to its Mortgage, then, upon Tenant being notified to that effect by such Mortgagee, this Lease shall be deemed prior to the lien of said Mortgage, whether this Lease is executed prior to or subsequent to the date of said Mortgage. With respect to any future Mortgages resulting from any other method of financing or refinancing or any future ground or underlying leases hereafter affecting the Lease or the Property of which the Premises forms a part, Tenant’s agreements in Section 14.1.1 are subject to Tenant’s receipt from the future Mortgagee (or other superior interest holder) a subordination, non-disturbance and attornment agreement (“SNDA”) on Mortgagee’s then standard form; which shall include Mortgagee’s agreement that following its acquisition of title to the Property (whether by foreclosure, deed-in-lieu of foreclosure or otherwise) it will recognize this Lease and agree that Tenant will be permitted to remain in undisturbed possession, use and occupancy of the Premises (as long as Tenant is not in default under the terms and conditions of this Lease after written notice by Landlord and the expiration of any applicable grace and cure periods).

14.1.4 SNDA from Current Mortgagee. Upon Tenant’s written request following the full execution of this Lease, and at Tenant’s expense, Landlord shall use good faith efforts to obtain from the holder of any Mortgage, an SNDA, which shall be on such Mortgagee’s standard form. In the interest of clarity, the Lease shall not be contingent upon Landlord obtaining an SNDA.

14.2 Limitation of Mortgagees’ Liability. Notwithstanding any other provision of this Lease to the contrary, no holder of any such Mortgage shall be obligated to perform or liable in damages for failure to perform any of Landlord’s obligations under this Lease unless and until such holder shall foreclose such mortgage or otherwise acquire title to the Property, and then shall only be liable for Landlord’s obligations arising or accruing after such foreclosure or acquisition of title. No such holder shall ever be obligated to perform or be liable in damages for any of Landlord’s obligations arising or accruing before such foreclosure or acquisition of title. Such holder’s obligations and liabilities shall in any event be subject to, and holder shall

34

have the benefit of, Section 16.16 hereof. Tenant shall never pay the Annual Base Rent, Additional Rent or any other charge more than ten (10) days prior to the due date thereof, and any payments made by Tenant in violation of this provision shall be a nullity as to such holder, and Tenant shall remain liable to such holder therefor. Tenant agrees on request of Landlord to execute and deliver from time to time any agreement which may be necessary to implement the provisions of this Section 14.2.

14.3 Estoppel Certificates. Tenant shall at any time, and from time to time, upon not less than five (5) business days prior written notice from Landlord execute, acknowledge and deliver to Landlord, to any prospective purchaser, or Mortgagee, a written certificate of Tenant in form satisfactory to Landlord: (a) ratifying this Lease; (b) expressing the Commencement Date and Expiration Date hereof; and (c) certifying (i) that this Lease is in full force and effect and has not been assigned, modified, supplemented or amended (except by such writings as shall be stated); (ii) that all conditions under this Lease to be performed by each party have been satisfied; (iii) that there are no defenses or offsets against the enforcement of this Lease by Tenant or Landlord as the case may be, or stating those claimed by such party; (iv) the amount of advance rental, if any, (or none if such is the case) paid by Tenant; (v) the date to which rental has been paid; and (vi) the amount of security deposited with Landlord. It is intended that any such certificate of Tenant delivered pursuant to this Section 14.3 may be relied upon by Landlord and any prospective purchaser or the Mortgagee of any part of the Property.

14.4 Quiet Enjoyment. Upon Tenant paying the Annual Base Rent and Additional Rent and performing all of Tenant’s obligations under this Lease, Tenant may peacefully and quietly enjoy the Premises during the Term as against all persons or entities lawfully claiming by or through Landlord; subject, however, to the provisions of this Lease and to the rights of Landlord’s Mortgagee.

14.5 Mortgagee Approval. Landlord and Tenant hereby agree that this Lease is subject to the review and approval of Landlord’s Mortgagee in accordance with the terms of the mortgage loan documents executed by Landlord in connection with its financing of the Property. Landlord shall submit this Lease to its Mortgagee promptly upon Tenant’s execution and delivery of this Lease to Landlord, and Landlord shall promptly advise Tenant of its Mortgagee’s decision.

16.8 Entire Agreement. Landlord’s employees, representatives and agents have no authority to make or agree to make a lease or any other agreement or undertaking in connection herewith. The submission of this document for examination and negotiation does not constitute an offer to lease, or a reservation of, or option for, the Premises, and this document shall be effective and binding only upon the execution and delivery hereof by both Landlord and Tenant. This Lease, including the Exhibits hereto, which are made part of this Lease, contain the entire agreement of the parties and all prior negotiations and agreements are merged herein. Neither Landlord nor Landlord’s agents have made any representations or warranties with respect to the Premises, the Building or this Lease except as expressly set forth herein, and no rights, easements or licenses are or shall be acquired by Tenant by implication or otherwise unless expressly set forth herein.

16.9 No Merger. There shall be no merger of this Lease or of the leasehold estate hereby created with the fee estate in the Premises or any part thereof by reason of the fact that the same person may acquire or hold, directly or indirectly, this Lease or the leasehold estate hereby created or any interest in this Lease or in such leasehold estate as well as the fee estate in the leasehold Premises or any interest in such fee estate.

16.10 Easements. Landlord reserves the right, from time to time, to grant easements and rights, make dedications, agree to restrictions and record maps affecting the Property as Landlord may deem necessary or desirable, so long as such easements, rights, dedications, restrictions, and maps do not unreasonably interfere with the use of the Premises by Tenant; and this Lease shall be subordinate to such instruments.

37

16.11 Bind and Inure. The terms, provisions, covenants and conditions contained in this Lease shall bind and inure to the benefit of Landlord and Tenant, and, except as otherwise provided herein, their respective heirs, legal representatives, successors and assigns. If two or more individuals, corporations, partnerships or other business associations (or any combination of two or more thereof) shall sign this Lease as Tenant, the liability of each such individual, corporation, partnership or other business association to pay Rent and perform all other obligations hereunder shall be deemed to be joint and several. All agreements, covenants and indemnifications contained herein or made in writing pursuant to the terms of this Lease by or on behalf of Tenant shall be deemed material and shall survive expiration or sooner termination of this Lease.

No waiver of any provision hereof shall be deemed a waiver of any other provision hereof or of any subsequent breach of the same or any other provision. No waiver of any breach shall affect or alter this Lease, but each and every term, covenant and condition of this Lease shall continue in full force and effect with respect to any other then existing or subsequent breach thereof. No reference to any specific right or remedy shall preclude the exercise of any other right or remedy permitted hereunder or that may be available at law or in equity. No failure by Landlord to insist upon the strict performance of any agreement, term, covenant or condition hereof, or to exercise any right or remedy consequent upon a breach thereof, and no acceptance of full or partial rent during the continuance of any such breach, shall constitute a waiver of any such breach, agreement, term, covenant or condition.

16.13 Tenant’s Financial Statements. Within ten (10) days following Landlord’s written request, Tenant shall furnish Landlord with copies of Tenant’s balance sheets, at the close of the most recently ended fiscal year, and Tenant’s statements of income and retained earnings for such year, prepared in accordance with generally accepted accounting principles and audited by Tenant’s independent certified public accountants (if audited financial statements for such fiscal year are available at such time). If audited financial statements for the most recently ended fiscal year are not available at the time of such request by Landlord, Tenant shall provide the most recent unaudited financial statements as are then available certified by Tenant’s chief financial officer or chief accounting officer (or the person filling the most comparable role) to be true and correct and free from material mis-statement. Notwithstanding the foregoing, Landlord may not request such financial statements except in connection with a sale of the Property or a mortgage financing or refinancing, or after an Event of Default which remains uncured. Landlord shall execute a commercially reasonable confidentiality agreement in connection with any requests made pursuant to this Section 16.13.

16.14 Attorney’s Fees. If on account of any default by Tenant in Tenant’s obligations under the terms of this Lease, it becomes necessary or appropriate for Landlord to employ attorneys or other persons to enforce any of Landlord’s rights or remedies hereunder, Tenant shall pay upon demand as Additional Rent hereunder all reasonable fees of such attorneys and other persons and all other costs of any kind so incurred.

16.15 Landlord Approvals. Whenever Tenant is required to obtain Landlord’s consent hereunder, Tenant agrees to reimburse Landlord all out-of-pocket expenses incurred by Landlord, including reasonable attorneys’ fees in order to review documentation or otherwise determine whether to give its consent and the fees of consultants, architects and engineers for the review of plans, specifications and drawings. Tenant shall pay Landlord’s invoice for any such amounts within ten (10) days following Landlord’s delivery of its invoice therefor. Any provision of this Lease which requires the Tenant to obtain Landlord’s consent to any proposed action by Tenant shall not be the basis for an award of damages or give rise to a right of setoff on Tenant’s behalf, but may be the basis for a declaratory judgment or injunction with respect to the matter in question.

16.16 Landlord’s Liability. Tenant shall look only to Landlord’s estate in the Property (or the proceeds thereof) for the satisfaction of Tenant’s remedies with respect to any liability, default or obligation of Landlord under this Lease or otherwise regarding Tenant’s leasing, use and occupancy of the Premises pursuant hereto, including without limitation for the collection of any monetary obligation, judgment or other judicial process requiring the payment of money by Landlord. Neither Landlord nor any of its members, stockholders, officers, directors, partners, trustees, beneficiaries or employees shall be personally liable

38

hereunder, nor shall any of its or their property, other than the Property, be subject to levy, execution or other enforcement procedure for the satisfaction of Tenant’s said remedies. Landlord shall not under any circumstances be liable for any special, indirect or consequential damages of Tenant, including lost profits or revenues. No owner of the Property shall be liable under this Lease except for breaches of Landlord’s obligations occurring while such party owns the Property.

16.17 Time of Essence. TIME IS OF THE ESSENCE with respect to the due performance of the terms, covenants and conditions herein contained; provided, however, that no delay or failure to enforce any of the provisions herein contained and no conduct or statement shall waive or affect any of Landlord’s rights hereunder.

16.18 Governing Law. This Lease and the rights and obligations of the parties hereunder shall be construed and enforced in accordance with the internal laws of the Commonwealth of Massachusetts, without regard to the principles of the conflict of laws.

16.19 Counterparts; Integration; Effectiveness. This Lease may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. Delivery of an executed counterpart of a signature page of this Lease by telecopy or electronic PDF transmission shall be effective as delivery of a manually executed counterpart of this Lease. This Lease shall become effective when it shall have been executed by each party hereto.

16.20 No Recording. Tenant shall not register or record this Lease or any memorandum or summary hereof without Landlord’s prior written consent, and in such case, Tenant shall be obligated to pay all charges and taxes incident to such registration or recording.

16.21 Confidentiality. Tenant agrees: (a) to treat the terms of the Lease, and the terms of any existing and future amendments and modifications to the Lease (the “Confidential Information”) as confidential during the term of this Lease and for the three (3) year period following the expiration or sooner termination of the Lease (the “Non-Disclosure Period”), (b) not to disclose, directly or indirectly, to any third party nor permit any third party (except Tenant’s professional advisors if such persons agree in writing to treat such information as confidential consistent with this Section) to have access to any or all of such Confidential Information during the Non-Disclosure Period, including, without limitation, any Building tenants and any brokers (except Tenant’s broker representing it with respect to this Lease if such person agrees in writing to treat such information as confidential consistent with this Section), and (c) to indemnify, defend and hold harmless Landlord from any loss, cost, expense, damage and liability, including Landlord’s legal fees and expenses, resulting from Tenant’s breach of the foregoing confidentiality agreements. Landlord acknowledges that, notwithstanding the foregoing, Tenant shall have the right to disclose such Confidential Information only to the extent that such disclosure is required by law (including rule, regulation or stock exchange listing requirement) or court order or by discovery rules in any legal proceeding. Tenant’s agreements and indemnity with respect to the Confidential Information shall survive the expiration or earlier termination of the Lease.

16.22 Force Majeure. Landlord shall be excused for the period of any delay in the performance of any obligations hereunder, when prevented from so doing by cause or causes beyond Landlord’s control including, without limitation, civil commotion, war, labor disputes or strikes, governmental regulations or controls, inspection delays by governmental authorities, delays in obtaining governmental permits, inability to obtain any material or services, casualty, acts of God, or the elements. Tenant shall similarly be excused for delay in the performance of obligations hereunder provided that: (a) nothing contained in this Section or elsewhere in this Lease shall be deemed to excuse or permit any delay in the payment of any sums of money required hereunder, or any delay in the cure of any default which may be cured by the payment of money; (b) performance of any particular obligation shall only be excused hereby during the period that such Force Majeure event actually causes such party to be prevented from such performance; (c) no reliance by Tenant

39

upon this Section shall limit or restrict in any way Landlord’s right of self-help as provided in this Lease; and (d) Tenant shall not be entitled to rely upon this Section unless it shall advise Landlord in writing, of the existence of any force majeure preventing the performance of an obligation of Tenant promptly after the commencement of the force majeure.

RECITALS:

A.     Landlord’s predecessor in interest, 111 MPA, and Tenant entered into that certain Agreement dated as of December 29, 2014 (the “Original Lease”) for approximately 3,317 rentable square feet on the third floor of the Building (the “Premises”).

B.    Landlord has succeeded to all of the right, title and interest of 111 MPA in and to the Property and the Lease. Tenant and Landlord now wish to further extend the Term of the Lease, which is now scheduled to expire on April 15, 2018.

C.    All terms, covenants and conditions contained in this Amendment shall have the same meaning as in the Lease, and, shall govern should a conflict exist with previous terms and conditions.

AGREEMENT

NOW, THEREFORE, in consideration of the foregoing recitals and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Landlord and Tenant hereby agree as follows:

1.     Capitalized Terms. Each capitalized term appearing but not defined herein shall have the meaning, if any, ascribed to such term in the Lease.

2.     Recitals; Term. The recitals above set forth are true and complete and are incorporated herein by reference. The Term of the Lease is currently scheduled to expire on April 15, 2018.

3.     Basic Rent; Additional Rent; Letter of Credit. (a) With respect to the period ending on April 15, 2018, Tenant shall continue to pay Annual Base Rent and all Additional Rent (including without limitation the Estimated Cost of Electricity Service) as is currently provided in the Lease.
