Fixed Rent for any partial calendar month following the Rent Commencement Date shall be prorated on a daily basis, and shall be due and payable in advance on the Rent Commencement Date.

2.7	Adjustments for Operating Expenses

A. Terms used herein are defined as follows:

Any of the services may be performed by subsidiaries or affiliates of Landlord, provided that the contracts for the performance of such services shall be competitive with comparable first class office buildings in the Boston metropolitan area.

- 2 -

For purposes of the preceding definition, the Operating Expenses for the Property shall include the cost (amortized with interest using generally accepted accounting principles) of any capital improvement (including, without limitation any equipment installed as a fixture) made by Landlord for the purpose of (a) reducing other operating costs; or (b) complying with any governmental requirement (including, without limitation, any law, ordinance, code, regulation or bylaw) which shall first become applicable to the Property after the date of this Lease.

Notwithstanding anything to the contrary contained in this Lease, the following are specifically excluded from Operating Expenses: (i) costs of capital improvements (except as otherwise set forth in this Section 2.7(A)(i) above); (ii) costs of correcting defects in design and/or construction of the Premises (excluding defects arising from Tenant’s Work), the Building, or costs in constructing any additional buildings or improvements on the Lot; (iii) depreciation (iv) interest and principal payments on mortgages and other debt costs, if any, and any penalties assessed as a result of Landlord’s late payments of such amounts; (v) real estate broker leasing commissions or compensation in connection with leasing or obtaining new tenants of the Building; (vi) any cost or expenditure (or portion thereof) for which Landlord is reimbursed, whether by insurance proceeds or otherwise; (vii) attorneys’ fees, costs disbursements, advertising and marketing and other expenses incurred in connection with the negotiation of leases with prospective tenants of the Building; (viii) rent for space which is not actually used by Landlord in connection with the management or operation of the Property; (ix) all costs or expenses (including fines, penalties and legal fees) incurred due to the violation by Landlord, its employees, agents, contractors or assigns of the terms and conditions of the Lease, or any valid, applicable building code, governmental rule, regulation or law; (x) except for the referenced management compensation, any overhead or profit increments to any subsidiary or affiliate of Landlord for services on or to the Property, to the extent that the costs of such services exceed market costs for such services; (xi) the cost of constructing tenant improvements for Tenant or any other tenant of the Property; (xii) contingency or replacement reserves (xiii) wages, salaries or other compensation to any employees or officers, directly or indirectly, above the level of property manager; (xiv) costs associated with the operation of the partnership or entity which constitutes the Landlord, as the same are distinguished from the costs of the operation of the Property; (xv) utility costs to the extent any tenant directly contracts and pays such costs to the supplier thereof; and (xvi) marketing and advertising expenses related to leasing the Building; and (xvii) costs, other than those incurred in ordinary maintenance and repair, for sculptures, paintings, fountains or other objects of art or the display of such item.

(2) The “Operating Statement” shall mean a statement rendered to Tenant by Landlord, which Landlord shall deliver to Tenant within one hundred twenty (120) days or as soon thereafter as reasonably possible after the end of each calendar year during the Term. The Operating Statement shall be in reasonable detail, certified by Landlord’s representative, and show the amount of the Operating Expenses for the Property and the Operating Expenses Allocable to the Premises for the preceding Lease Year or fraction thereof, as the case may be.

(3) The phrase “Operating Expenses Allocable to the Premises” means Tenant’s Proportionate Share of the Operating Expenses for the Property.

- 3 -

(4) In any calendar year when the Building has an average annual occupancy rate of less than ninety-five percent (95%), then, for the purpose of this Section 2.7, items which are variable according to occupancy comprising the Operating Expenses for the Property shall be equitably adjusted as though the Building were ninety-five percent (95%) occupied. In any calendar year when the Building has an average annual occupancy rate of ninety-five percent (95%) or more then the Operating Expenses for the Property shall be the actual Operating Expenses for the Property.

B. If, with respect to any calendar year or fraction thereof ending within the Term, the Operating Expenses Allocable to the Premises for a full calendar year exceed Tenant’s Operating Expense Base then, within thirty (30) days after receipt by Tenant of the Operating Statement, Tenant shall pay to Landlord, as additional rent, the amount of such excess, less any amounts previously paid by Tenant pursuant to Paragraph C below. In the event the actual amounts due for the period encompassed by Landlord’s statement are less than the estimated amounts theretofore paid by Tenant with respect to such period, Tenant shall receive a credit for the excess amounts paid, which credit may be applied against subsequent installments of additional rent due under this Section 2.7, or, if this Lease has already been terminated, Landlord shall refund such amounts to Tenant.

C. Landlord shall have the right from time to time by notice to Tenant to estimate amounts required to be paid by Tenant under this Section 2.7 to reflect Landlord’s latest reasonable estimate of the actual amounts which will be due from Tenant hereunder based upon then current budgets and expenditures incurred to date. Following any notice by Landlord requesting that Tenant make estimated monthly payments toward its obligation under this Section 2.7, Tenant shall make such monthly payments in accordance with such notice, until further notice is given by Landlord. If the Term of this Lease expires prior to the determination by Landlord and payment by or refund to Tenant of any amounts due hereunder, Tenant’s obligation to pay and Landlord’s obligation to refund such amounts for any portion of the Term of this Lease shall survive the termination of this Lease even though determination of such amounts may not be made until after such termination.

D. Landlord agrees to keep books and records showing Operating Expenses for the Property in accordance with a system of accounts and accounting practices consistently maintained. Tenant shall have the right, at its sole expense, upon reasonable prior notice to Landlord, to inspect such books and records at Landlord’s office during business hours for one hundred twenty (120) days following receipt of an annual Operating Statement; provided, however, that such right may not be exercised by an agent of Tenant whose fee is based on the success of the inspection. Should such inspection reveal errors in excess of five percent (5%), Landlord shall reimburse Tenant for its out of pocket expenses of such inspection.

2.8	Adjustments for Real Estate Taxes

A. Terms used herein are defined as follows:

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

- 4 -

(2) “Landlord’s Tax Expenses” with respect to any Tax Year means the aggregate Real Estate Taxes on the Property with respect to that Tax Year, reduced by any abatements actually received with respect to that Tax Year.

(3) “Real Estate Taxes for the Property” means all taxes and special assessments of every kind and nature assessed by any governmental authority on the Lot or the Building or the Property which Landlord shall become obligated to pay because of or in connection with the ownership, leasing and operation of the Lot, the Building and the Property and commercially reasonable expenses of any proceedings for abatement of taxes. The amount of special taxes or special assessments to be included shall be limited to the amount of the installment (plus any interest, other than penalty interest, payable thereon) of such special tax or special assessment required to be paid during the year in respect of which such taxes are being determined. There shall be excluded from such taxes all income, estate, succession, inheritance and transfer taxes; provided, however, that if at any time during the Term the present system of ad valorem tax of real property shall be changed so that in lieu of the whole or any part of the ad valorem tax on real property, there shall be assessed on Landlord a capital levy or other tax on the gross rents received with respect to the Lot or Building or Property, or a federal, state, county, municipal, or other local income, franchise, excise or similar tax, assessment, levy or charge (distinct from any now in effect in Massachusetts) measured by or based, in whole or in part, upon any such gross rents, then any and all of such taxes shall be included within the term “Real Estate Taxes” but only to the extent that the same would be payable if the Lot, Building, or Property were the only property of Landlord.

(4) The “Tax Statement” shall mean a statement rendered to Tenant by Landlord within thirty (30) days or as soon thereafter as reasonably possible after receipt of the real estate tax bills for each fiscal year (or partial year, if applicable) during the Term and within ninety (90) days or as soon thereafter as reasonably possible after Lease termination. The Tax Statement shall be in reasonable detail and certified by a representative of Landlord showing for the respective fiscal year or fraction thereof, as the case may be, Real Estate Taxes for the Property.

(5) “Tax Expenses Allocable to the Premises” means Tenant’s Proportionate Share of Real Estate Taxes for the Property.

B. If with respect to any Tax Year, Tax Expenses Allocable to the Premises exceed Tenant’s Tax Base, then within thirty (30) days after receipt by Tenant of the Tax Statement, Tenant shall pay to Landlord, as additional rent, the amount of such excess, less any amounts previously paid by Tenant pursuant to Paragraph C below. In the event the actual amounts due for the period encompassed by the Tax Statement are less than the estimated amounts theretofore paid by Tenant with respect to such period, Tenant shall receive a credit for the excess amounts paid, which credit may be applied against subsequent installments of additional rent due under this Section 2.8, or, if this Lease has already been terminated, Landlord shall refund such amounts to Tenant. Appropriate prorations shall be made for those periods at the beginning or end of the Term which are less than a full Tax Year.

C. Landlord shall have the right from time to time by notice to Tenant to estimate amounts required to be paid by Tenant under this Section 2.8 to reflect Landlord’s latest

- 5 -

reasonable estimate of the actual amounts which will be due from Tenant hereunder. Following any notice by Landlord requesting that Tenant make estimated monthly payments toward its obligation under this Section 2.8, Tenant shall make such monthly payments in accordance with such notice, until further notice is given by Landlord. If the Term of this Lease expires prior to the determination by Landlord and payment by or refund to Tenant of any amounts due hereunder, Tenant’s obligation to pay and Landlord’s obligation to refund such amounts for any portion of the Term of this Lease shall survive the termination of this Lease even though determination of such amounts may not be made until after such termination.

D. To the extent that Real Estate Taxes shall be payable to the taxing authority in installments for periods less than a Tax Year, the foregoing statement shall be rendered and payments made on account of such installments with respect to such periods rather than with respect to such full Tax Year.

E. No decrease in Real Estate Taxes for the Property with respect to any Tax Year shall result in a reduction of the Fixed Rent payable by Tenant.

2.9	Electricity Charge

Tenant shall pay $1.50 per rentable square foot per year for the estimated cost of electricity for lights and outlets within the Premises, payable in equal monthly installments with the Fixed Rent and subject to the reconciliation process set forth in Section 2.7(B). The actual cost of Tenant’s share of electricity within the Premises shall be included in the annual Operating Statement along with Tenant’s Proportionate Share of common area electricity. Tenant shall not exceed electrical usage of 8.0 ▇▇▇▇▇ per square foot included in the Premises. If not already submetered, Landlord shall install a submeter in the Premises at its sole cost on or before the Commencement Date.

2.10	Due Date of Additional Payments; No Offsets

Except for Operating Expenses for the Property estimated in accordance with Section 2.7(C) and Real Estate Taxes for the Property estimated in accordance with Section 2.8(C) (both of which shall be paid in advance on the first of each month with Fixed Rent) or as otherwise specifically provided herein, any sum, amount, item or charge designated or considered as additional rent in this Lease shall be paid by Tenant to Landlord on or before the thirtieth (30th) day after Landlord notifies Tenant of the amount payable. Any such notice shall specify in reasonable detail the basis of such additional rent. Additional rent shall be paid by Tenant to Landlord without offset or deduction.

2.11	Late Payment of Rent

If any installment of Fixed Rent or payment of additional rent is paid after the date the same was due, it shall bear interest from the due date at the rate published as the “prime rate” in The Wall Street Journal, as it may be adjusted from time, to time, plus four percent (4%) per annum, but in no event more than the maximum rate of interest allowed by law, the payment of which shall be additional rent.

- 6 -

2.12	Renewal Option

A. Provided that (i) a default as described in Section 7.1 of the Lease shall not have occurred and be continuing beyond any applicable cure period on the day on which Tenant purports to exercise the Renewal Option (defined below) or on the first day of the Renewal Term (as defined below), and (ii) the Tenant named herein or a Tenant Affiliate is actually occupying the entire Premises as of each of said dates, Tenant shall have the option (“Renewal Option”) to renew the Term of this Lease for one (1) additional period of five (5) years (the “Renewal Term”), unless sooner terminated as provided in this Lease, subject to all the terms of this Lease except for the change in Fixed Rent as provided below.

B. Tenant shall exercise the Renewal Option, if at all, by giving written notice (“Notice to Renew”) of exercise to Landlord no later than nine (9) months prior to expiration of the Term. If Tenant fails to give such notice to Landlord within such time, Tenant shall be deemed to have waived the right to exercise the Renewal Option. Upon Tenant’s exercise of the Renewal Option, the Term shall be deemed to include the Renewal Term.

C. The annual Fixed Rent payable during the Renewal Term shall be the fair market rent for comparable first class office space in effect in the 128 Office market on the commencement date of the Renewal Term (the “Fair Market Rent”). The determination of Fair Market Rent (whether such determination is made by Landlord and/or Tenant or the brokers referenced herein) shall take into account factors such as (but not limited to) the rental rate currently required to be paid by Landlord for space at the Property, the term of the lease, the base year for operating expenses and taxes, brokerage commissions, the then condition of the applicable space and the level of any inducements being offered.

D. The Fair Market Rent shall be determined as follows:

(1) Within fifteen (15) calendar days after receipt of a Notice to Renew, Landlord shall furnish Tenant with Landlord’s estimate of Fair Market Rent (“Landlord’s Rent Estimate”).

(2) Within fifteen (15) calendar days after receipt of Landlord’s Rent Estimate, Tenant shall respond and specify whether and the extent to which Tenant disputes Landlord’s Rent Estimate.

(3) If Tenant disputes Landlord’s Rent Estimate, Tenant and Landlord shall negotiate in good faith for an additional thirty (30) calendar days to reach agreement on the Fair Market Rent.

(4) If Tenant and Landlord shall not have reached agreement as to the Fair Market Rent by the date which is ninety (90) calendar days after the receipt by Landlord of the Notice to Renew, Landlord and Tenant, within ten (10) calendar days after the expiration of such ninety (90) calendar day period, shall each select a real estate broker affiliated with a major Boston commercial real estate brokerage firm and having at least fifteen (15) years’ experience in the field with office properties similar to the Building in the Boston area to determine the Fair Market Rent. The two selected brokers shall within fourteen (14) calendar days appoint a third broker having the qualifications described above (the “Third Broker”). Each party shall pay the fees and expenses of the broker it selected and the fees and expenses of the Third Broker shall be borne equally by both parties.

- 7 -

(5) Within thirty (30) calendar days after the selection of the Third Broker, the brokers shall determine the Fair Market Rent. In the event that the brokers have not agreed upon the Fair Market Rent within such thirty (30) day period, each broker shall simultaneously deliver, within ten (10) calendar days, a written appraisal of the Fair Market Rent to Landlord and Tenant, and the Fair Market Rent shall be the average of the two closest appraisals.

(6) If Landlord or Tenant shall have failed to designate a broker within the time period provided therefor above, then the broker which has been designated, whether by Landlord or Tenant, shall alone make the determination of the Fair Market Rent. If Tenant and Landlord have both designated brokers but the two brokers so designated do not agree upon and designate the third broker willing so to act within the time period provided therefor above, the Tenant, the Landlord or either broker previously designated may request the Greater Boston Real Estate Board, Inc. to designate the third broker willing so to act and a broker so appointed shall, for all purposes, have the same standing and powers as though such broker had been seasonably appointed by the brokers first appointed. In case of the inability or refusal to serve of any person designated as a broker, or in case any broker for any reason ceases to be such, a broker to fill such vacancy shall be appointed by the Tenant, the Landlord, the broker first appointed or the said Greater Boston Real Estate Board, Inc., as the case may be, whichever made the original appointment.

Liens

Tenant will not permit any mechanic’s lien or other liens to be placed upon Tenant’s Space or the Property as a result of any materials or labor ordered by Tenant or any of Tenant’s agents, officers, or employees.

If Tenant fails to comply with the foregoing provisions of this Section 3.4, Landlord may exercise its self-help rights set forth in Section 8.6 to discharge or bond over the lien at Tenant’s sole cost and expense in any manner deemed appropriate by Landlord in its sole discretion.

3.5	Soft Cost Allowance

Simultaneously with submission of such invoice, Tenant shall provide Landlord documented evidence of such expenditures in form reasonably satisfactory to Landlord. Landlord shall pay Tenant an amount equal to such properly invoiced and documented expenses up to the Allowance.

(a) Without prior written consent of Landlord, not to assign, mortgage, pledge or otherwise transfer this Lease or its rights hereunder, or to make any sublease, or to permit occupancy of the Premises or any part thereof by anyone other than Tenant, except that Tenant may assign this Lease without Landlord’s consent to (i) an entity controlling, controlled by or under common control with Tenant, or (ii) an entity purchasing all of Tenant’s business, assets and liabilities or into which Tenant is merged or consolidated (each entity described in clauses (i) and (ii) of this sentence, a “Tenant Affiliate”), only if such Tenant Affiliate has a net worth at least equal to that of Tenant as of the date of this Lease. In connection with any request by Tenant for such consent to assignment or subletting, to submit to Landlord in writing (i) the name of the proposed assignee or sublessee, (ii) such information as to its financial responsibility and standing as Landlord may reasonably require, (iii) the basic terms and provisions upon which the proposed assignment or subletting is to be made and other reasonable information requested by Landlord; and (iv) the nature of its business and proposed use of the Premises. Tenant shall supply such additional information as Landlord reasonably requests.

(b) Tenant shall not offer to make or enter into negotiations with respect to an assignment or sublease (i) to any tenant in the Building or the adjacent building at ▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇▇▇▇, unless Landlord has no other space in the Building suitable to accommodate such tenant, (ii) to any party with whom, to Tenant’s knowledge (after first consulting with Landlord), Landlord is then negotiating (or with which it has negotiated in the last six months) with respect to space in the Building or such adjacent building, or (iii) to any party which would be of such type, character or condition as to be inappropriate as a tenant for a comparable office building.

- 14 -

(c) Except with respect to an assignment or sublease to a Tenant Affiliate, if Tenant intends to assign this Lease or sublease fifty percent (50%) or more of the Premises, it shall notify Landlord thereof together with identification of the space involved and the contemplated economic terms (“Tenant’s Assignment/Sublease Notice”), and Landlord shall have the option, exercisable by notice to Tenant given within fifteen (15) days after receipt of any such notification and information, to terminate this Lease in the case of a proposed assignment or to terminate this Lease with respect to the space to be sublet in the case of a proposed sublease of at least fifty percent (50%) of the Premises, which termination shall be effective as of the commencement date of such assignment or sublease set forth in Tenant’s Assignment/Sublease Notice. In no event shall Landlord’s right of recapture apply in case of a sublease to a Tenant Affiliate where Tenant will continue to occupy a substantial portion of the Premises.

(d) If Landlord does not exercise its right to terminate this Lease pursuant to the foregoing provisions, Landlord shall not unreasonably withhold or delay its consent to an assignment or subletting materially consistent with the information supplied by Tenant in its notification, provided that the terms and provisions of such assignment or subletting, mutatis, mutandis, shall specifically make applicable to the assignee or sublessee all of the provisions of this Section 5.6 so that Landlord shall have against the assignee or sublessee all rights with respect to any further assignment and subletting which are set forth herein; no assignment or subletting shall affect the continuing primary liability of Tenant (which, following assignment, shall be joint and several with the assignee); no consent to any of the foregoing in a specific instance shall operate as a waiver in a subsequent instance; and no assignment shall be binding upon Landlord or any of Landlord’s mortgagees, unless such assignee or subtenant agrees to be bound by all of Tenant’s obligations set forth in this Lease, mutatis mutandis. Should Landlord exercise its right to terminate this lease to only a portion of the Premises, Tenant shall be obligated to reimburse Landlord for the cost of demising walls, doors and partitions in compliance with applicable codes and at Building standard finishes, but only to the extent that such demising would have occurred had the Landlord not exercised such termination right and Tenant proceeded with its contemplated assignment or sublease.

(e) It shall be reasonable for Landlord to refuse consent to any assignment or sublease to any governmental agency or to any entity which by reputation or expected use is not comparable to other types of tenants in the Building or to an entity which is a tenant of the Property or the adjacent building for which Landlord has other suitable accommodations for such tenant in such buildings or to an entity which does not have, in Landlord’s sole good faith determination, a net worth equal or greater to Tenant’s net worth as of the date of this Lease or if the assignment or sublease would cause Landlord to be in violation or any laws or any other lease, Mortgage or other agreement. If Tenant disputes Landlord’s decision to deny consent to an assignment or sublease, Tenant’s sole remedy shall be to seek injunctive relief. Depending on assignee’s or sublessee’s financial standing, Landlord may require a security deposit as a condition of its consent.

Without limitation of the rights of Landlord hereunder, if there is an assignment of this Lease by Tenant or a subletting of the Premises by Tenant at a rent which, in either case, exceeds

- 15 -

the rent payable hereunder by Tenant, Tenant shall pay to Landlord, as additional rent, fifty percent (50%) of such excess rent, after first deducting the reasonable costs incurred by Tenant in connection with such assignment or sublease, including without limitation brokerage fees, attorneys fees, improvement allowances and other tenant concessions. For purposes of this Section 5.6, the term “rent” shall mean all Fixed Rent, additional rent or other payment and/or consideration payable hereunder.

The term “subletting” or “sublease” shall not only mean a sublease, but also any license or concession agreement or agreement for the use, occupancy or utilization of the Premises. Tenant shall reimburse Landlord for its reasonable legal and other expenses in connection with any request for consent under this Section.

5.7	Indemnity; Insurance; Waiver of Subrogation

A. To defend with counsel first reasonably approved by Landlord, save harmless, and indemnify Landlord, its agents and employees, from any liability for injury, loss, accident or damage to any person or property, and from any claims, actions, proceedings and expenses and costs in connection therewith (including without limitation reasonable counsel fees), (i) arising from (a) Tenant’s violation of this Lease or the negligence or other misconduct of Tenant, its employees, agents or invitees, or (b) from any use made or thing done or occurring on the Premises not due to the gross negligence or willful misconduct of Landlord or its agents or employees, or (ii) resulting from the failure of Tenant to perform and discharge its covenants and obligations under this Lease;

C. The limits of insurance required by this Lease, or as carried by Tenant, shall not limit the liability of Tenant or relieve Tenant of any obligation thereunder, except to the extent provided for under Section 4.7(c) of this Lease.

The above requirements shall apply equally to any contractor or subcontractor engaged by Tenant’s contractor.

F. Tenant insurance requirements stipulated in this Section 5.7 are based upon current industry standards. Landlord reserves the right to require additional coverage or to increase limits consistent with changes in such industry standards.

ARTICLE VI

CASUALTY AND TAKING

6.1	Termination or Restoration; Rent Adjustment

If during the Term all or any substantial part of the Premises or the Building or the Lot are damaged materially by fire or other casualty or by action of public or other authority in consequence thereof, or are taken by eminent domain, this Lease shall terminate at Landlord’s election, which may be made notwithstanding Landlord’s entire interest may have been divested, by notice given to Tenant within forty-five (45) days after the date of casualty or taking specifying the effective date of termination. If this Lease is not so terminated by Landlord, Landlord shall provide to Tenant in writing within forty-five (45) days after the casualty or taking the reasonable estimate from a contractor engaged by Landlord of the cost of repair and when the Premises or the Common Areas of the Building, as the case may be, could be restored to proper condition for occupancy by Tenant.

Unless terminated pursuant to the foregoing provisions, this Lease shall remain in full force and effect following any such damage or taking, subject, however, to the following provisions. If in any such case the Premises are rendered unfit for use and occupancy and this Lease is not so terminated, Landlord shall use commercially reasonable and diligent efforts (following the expiration of the period in which Landlord or Tenant may terminate this Lease pursuant to the foregoing provisions of this Section 6.1) to put the Premises and the common areas, or in case of taking what may remain thereof (excluding in case of both

- 20 -

casualty and taking any items installed or paid for by Tenant which Tenant may be required to remove), into proper condition for use and occupancy (in the case of a taking to the extent permitted by the net award of damages and in the case of a casualty, to the extent of the net insurance proceeds and any retained amount), and a just proportion of the Fixed Rent and additional rent according to the nature and extent of the injury shall be abated from the date of such casualty or taking until the Premises or such remainder shall have been put by Landlord in such condition; and in case of taking which permanently reduces the area of the Premises, a just proportion of the Fixed Rent and additional rent shall be abated for the remainder of the Term.

Landlord reserves to itself any and all rights to receive awards made for damages to the Premises and Building and Lot and the leasehold hereby created, or any one or more of them, accruing by reason of exercise of eminent domain or by reason of anything lawfully done in pursuance of public or other authority. Tenant hereby releases and assigns to Landlord all Tenant’s rights to such awards, and covenants to deliver such further assignments and assurances thereof as Landlord may from to time request. Tenant hereby irrevocably designates and appoints Landlord as its attorney-in-fact to execute and deliver in Tenant’s name and on its behalf any such further assignments thereof. Notwithstanding the foregoing, Tenant shall be entitled to any damages for personal property of Tenant and for reasonable relocation expenses which are available to Tenant in a separate action or separate award.

ARTICLE VII

DEFAULT

7.1	Events of Default

If any default, breach or failure of performance by Tenant of any agreement, covenant, condition, provision, or warranty contained herein continues, in cases of failure to pay Fixed Rent or additional rent or other payments required hereunder (i) within five (5) business days after notice from Landlord to be given no more than two (2) times in any calendar year (or after two (2) such notices in any calendar year, on the date due), or (ii) in cases other than monetary defaults continuing for more than thirty (30) days after notice from Landlord and such additional time, if any, as is reasonably necessary to cure the default if the default is of such a nature that it cannot reasonably be cured in thirty (30) days provided Tenant commences to cure promptly and diligently pursues the cure to completion but in no case more than one hundred twenty (120) days after notice from Landlord; or if Tenant or any guarantor or any guarantors of any of Tenant’s obligations under this Lease is not paying its debts as such debts become due, becomes insolvent, files or has filed against it (and in the case of an involuntary petition such is not dismissed within 30 days after the filing) a petition under any chapter of the U.S. Bankruptcy Code (or any similar petition under any insolvency law of any jurisdiction), proposes any dissolution, liquidation, composition, financial reorganization or recapitalization with creditors, makes an assignment or trust mortgage for the benefit of creditors, or if a receiver, trustee, custodian or similar agent is appointed or takes possession with respect to any property or business of Tenant or such guarantor, then in any such case, whether or not the Term shall have begun, Landlord may immediately, or at any time while such default exists and without further

- 21 -

notice, terminate this Lease by notice to Tenant, specifying the date on which this Lease shall terminate and this Lease shall come to an end on the date specified therein as fully and completely as if such date were the date herein originally fixed for the expiration of the Term, and Tenant shall then quit and surrender the Premises to Landlord, but Tenant shall remain liable as hereinafter provided.

7.2	Landlord’s Rights and Tenant’s Obligations after Termination

In the event that this Lease is terminated under any of the provisions contained in Section 7.1 or shall be otherwise terminated for breach of any obligation of Tenant, Landlord shall have the right to exercise the following remedies:

(A) Tenant shall pay forthwith to Landlord upon demand, as compensation, the excess of the total rent reserved for the residue of the Term over the fair market rental value of the Premises for said residue of the Term (after deduction of all anticipated expenses of reletting) discounted to present value determined by reference to The Wall Street Journal listing of “Treasury Bonds, Notes, and Bills” (representative of New York, based on transactions of $1,000,000 or more), of the yield to maturity on issues closest to the expiration of the Term of this Lease. In calculating the rent reserved there shall be included, in addition to the Fixed Rent and all additional rent, the value of all other considerations agreed to be paid or performed by Tenant for said residue. For purposes of clarification, Landlord shall not be obligated to wait for the original expiration of the Term of the Lease or until the Premises have been relet to exercise the foregoing remedy. Landlord may exercise such remedy immediately upon termination of the Lease, and Tenant shall be obligated to pay the applicable damages immediately upon Landlord’s demand. In no event shall Tenant be entitled to a credit if the excess of the fair market rental value of the Premises for the residue of the Term exceeds the total rent reserved for the residue of the Term.

(B) Tenant as an additional and cumulative obligation shall pay punctually to Landlord all the sums and perform all the obligations which Tenant covenants in this Lease to pay and to perform in the same manner and to the same extent and at the same time as if this Lease had not been terminated. In calculating the amounts to be paid by Tenant under the foregoing covenant Tenant shall be credited with any amount paid to Landlord as compensation as in this Section 7.2 provided and also with the net proceeds of any rent obtained by Landlord by reletting the Premises, after deducting reasonable expenses in connection with such reletting, including, without limitation, repossession costs, brokerage commissions, fees for legal services and expenses of preparing the Premises for such reletting, it being agreed by Tenant that Landlord may (i) relet the Premises or any part or parts thereof, for a term or terms which may, at Landlord’s option, be equal to or less than or exceed the period which would otherwise have constituted the balance of the Term and may grant such concessions and free rent as Landlord in its sole judgment considers advisable or necessary to relet the same, and (ii) in connection with such reletting, may make such alterations, repairs and decorations in the Premises as Landlord in its sole judgment considers advisable or necessary to relet the same, and no action of Landlord in accordance with the foregoing or failure to relet or to collect rent under reletting shall operate or be construed to release or reduce Tenant’s liability as aforesaid. In no event shall Tenant be entitled to a reletting credit that exceeds the amount due to Landlord under this Section 7.2.

- 22 -

In lieu of any other damages or indemnity and in lieu of full recovery by Landlord of all sums payable under all the foregoing provisions of this Section 7.2, Landlord may, by written notice to Tenant, at any time after this Lease is terminated under any of the provisions contained in Section 7.1 or is otherwise terminated for breach of any obligation of Tenant and before such full recovery, elect to recover, and Tenant shall thereupon pay, as liquidated damages, an amount equal to the aggregate of the Fixed Rent and additional rent accrued under Sections 2.6, 2.7 and 2.8 in the twelve (12) months ended next prior to such termination (or, if less than 12 months remains in the Term, for such number of months so remaining in the Term) plus the amount of Fixed Rent and additional rent of any kind accrued and unpaid at the time of termination and less the amount of any recovery by Landlord under the foregoing provisions of this Section 7.2 up to the time of payment of such liquidated damages.

Nothing contained in this Lease shall limit or prejudice the right of Landlord to prove for and obtain in proceedings for bankruptcy or insolvency 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.

ARTICLE VIII

MISCELLANEOUS

8.1	Notice of Lease; Consent and Approval; Notices; Bind and Inure

The titles of the Articles are for convenience only and are not to be considered in construing this Lease. Tenant agrees not to record this Lease, but upon request of either party both parties shall execute and deliver a notice of this Lease pursuant to M.G.L. c. 183 § 4, and if this Lease is terminated before the term expires, an instrument in such form acknowledging the date of termination. Whenever any notice, approval, consent, request or election is given or made pursuant to this Lease it shall be in writing. Communications and payments shall be addressed if to Landlord at Landlord’s Original Address or at such other address as may have been specified by prior notice to Tenant, and if to Tenant, at Tenant’s Original Address or after the Commencement Date at the Premises with a copy to ▇▇▇▇▇ ▇▇▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ and ▇▇▇▇▇, PC, ▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇, Attn: ▇▇▇▇▇ ▇▇▇▇▇▇▇▇, Esq., or at such other place as may have been specified by prior notice to Landlord. Any communication so addressed shall be deemed duly given upon delivery in hand or one day after it is sent by overnight mail or by regularly recognized overnight courier which supplies a receipt therefor, or two (2) days after it is mailed by registered or certified mail, return receipt requested. If Landlord by notice to Tenant at any time designates some other person to receive payments or notices, all payments or notices thereafter by Tenant shall be paid or given to the person designated until notice to the contrary is received by Tenant from Landlord. The obligations of this Lease shall run with the land, and this Lease shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns, subject to the limitations set forth in Section 8.16.

- 23 -

8.2	Landlord’s Failure to Enforce

The failure of Landlord to seek redress for violation of, or to insist upon strict performance of, any covenant or condition of this Lease, shall not be deemed a waiver of such violation nor prevent a subsequent act which would have originally constituted a violation, from having all the force and effect of an original violation. The receipt by Landlord of Fixed Rent or additional rent with knowledge of the breach of any covenant of this Lease shall not be deemed a waiver of such breach. No provision of this Lease shall be deemed to have been waived by Landlord or Tenant unless such waiver is in writing signed by the party to be charged. No consent or waiver, express or implied, by Landlord or Tenant, to or of any breach of any agreement or duty shall be construed as a waiver or consent to or of any other breach of the same or any other agreement or duty.

8.3	Acceptance of Partial Payments of Rent; Delivery of Keys

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

8.4	Cumulative Remedies

The specific remedies to which Landlord may resort under the terms of this Lease are cumulative and are not intended to be exclusive of any other remedies or means of redress to which it may be lawfully entitled in case of any breach or threatened breach by Tenant of any provisions of this Lease. In addition to other remedies provided in this Lease, Landlord shall be entitled to the restraint by injunction of the violation or attempted or threatened violation of any of the covenants, conditions or provisions of this Lease or to a decree compelling specific performance of any such covenants, conditions or provisions.

8.5	Partial Invalidity

If any term of this Lease, or the application thereof to any person or circumstances, shall to any extent be invalid or unenforceable, the remainder of this Lease, or the application of such term to persons or circumstances other than those as to which it is invalid or unenforceable shall not be affected thereby, and each term of this Lease shall be valid and enforceable to the fullest extent permitted by law.

8.6

Self-Help

If Tenant shall at any time default in the performance of any obligation under this Lease, after the expiration of any applicable notice and cure periods, Landlord shall have the right, but shall not be obligated, to enter upon the Premises and to perform such obligation notwithstanding the fact that no specific provision for such substituted performance by Landlord is made in this

- 24 -

Lease with respect to such default. In performing such obligation, Landlord may make any payment of money or perform any other act. All sums so paid by Landlord (together with interest at the rate of two and one-half (2.5%) percentage points over the then prevailing prime rate as published in The Wall Street Journal) and all necessary incidental costs and expenses in connection with the performance of any such act by Landlord, shall be deemed to be additional rent under this Lease and shall be payable to Landlord immediately on demand. Landlord may exercise the foregoing rights without waiving any other of its rights or releasing Tenant from any of its obligations under this Lease.

8.7	Estoppel Certificate

Each party agrees from time to time, upon not less than fifteen (15) business days’ prior written request by the other party, to execute, acknowledge and deliver to the requesting party a statement in writing certifying, to the extent the same is accurate such information that is reasonably requested by the parties including without limitation, that this Lease is unmodified and in full force and effect and to their knowledge that there are no uncured defaults of Landlord or Tenant under this Lease, that the other party has no defenses, offsets or counterclaims against its obligations under the Lease, including without limitation to pay the Fixed Rent and additional rent and to perform its other covenants under this Lease (or, if there have been any modifications that the same is in full force and effect as modified and stating the modifications and, if there are any defenses, offsets, counterclaims, or defaults, setting them forth in reasonable detail), the dates to which the Fixed Rent, additional rent and other charges have been paid and such other matters relating to the Lease as may be reasonably requested. Any such statement delivered pursuant to this Section 8.7 may be relied upon by the parties and by a prospective purchaser or mortgagee of the Property or any prospective assignee, of any mortgagee of the Property, or by a prospective assignee, subtenant or lender of Tenant interest in this Lease, as the case may be.

8.8	Waiver of Subrogation

Any property damage insurance carried by either party with respect to the Premises or property therein shall include a clause or endorsement denying to the insurer rights of subrogation against the other party to the extent rights have been waived by the insured prior to occurrence of injury or loss. Each party, notwithstanding any provisions of this Lease to the contrary, hereby waives any and all rights of recovery against the other for or arising out of damage to or destruction of any property of the other or injury or loss due to hazards to the extent that the other’s insurance policies then in force or the policies required by this Lease, whichever is broader, insure against such damage or destruction.

8.9	All Agreements Contained

This Lease contains all of the agreements of the parties with respect to the subject matter thereof and supersedes all prior dealings between them with respect to such subject matter.

8.10

Brokerage

Each party represents that it has had no dealings with any broker or agent other than the Broker(s) identified in Section 1.2 in connection with this Lease and covenants to defend, hold harmless and indemnify the other party and its agents from and against any and all cost, expense or liability resulting from a breach of the foregoing representation. Landlord will pay the commissions due the aforesaid Brokers in accordance with separate commission agreements.

- 25 -

8.11	Submission Not an Option

The submission of this Lease or a summary of some or all of its provisions for examination does not constitute a reservation of or option for the Premises or an offer to lease, and it is not effective as a lease or otherwise until the execution by and delivery to both Landlord and Tenant.

8.12	Applicable Law

This Lease, and the rights and obligations of the parties hereto, shall be construed and enforced in accordance with the laws of the Commonwealth of Massachusetts.

8.13	Waiver of Jury Trial

LANDLORD AND TENANT HEREBY WAIVE TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM BROUGHT BY EITHER OF THE PARTIES HERETO AGAINST THE OTHER, ON OR IN RESPECT TO ANY MATTER WHATSOEVER ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS LEASE, THE RELATIONSHIP OF LANDLORD AND TENANT HEREUNDER, TENANT’S USE OR OCCUPANCY OF THE PREMISES, AND/OR CLAIM OF INJURY OR DAMAGES.

8.14	Access and Security

Tenant shall have access to the Premises at all times, except in the event of an emergency or for safety precautions. The Building is accessed by an automated card key system. Landlord may require that parties desiring to enter the Building after regular office hours must provide proper identification. Tenant shall be responsible for any security required for Tenant’s property in or around the Premises, including, but not limited to, the loading area.

8.15

Holdover

Should Tenant holdover in occupancy of the Premises after the expiration or other termination of the Term of this Lease, without the consent of Landlord, such holding over shall be as a tenant at sufferance and Tenant shall be liable to Landlord for use and occupancy equal to one hundred fifty percent (150%) of (a) the Fixed Rent, plus (b) any additional rent in effect at the end of the Term, and also for all damages sustained by Landlord on account of such holding over. The provisions of this Section shall not operate as a waiver of any right of reentry provided in this Lease.

8.16	Limitation on Liability

In consideration of the benefits accruing hereunder, Tenant hereby covenants and agrees that, in the event of any actual or alleged failure, breach or default hereunder by Landlord:

(a) The obligations of Landlord under this Lease do not constitute personal obligations of the members, trustees, individual partners, directors, officers or shareholders of Landlord or any constituent entity of Landlord, and Tenant shall not seek recourse against the members, trustees, partners, directors, officers or shareholders of Landlord or any constituent entity of Landlord, or any of their personal assets for satisfaction of any liability with respect to this Lease.

- 26 -

(b) Tenant’s sole and exclusive remedy shall be against Landlord’s interest in the Property and the proceeds therefrom.

8.17	Security Deposit

(a) Tenant shall provide Landlord with a letter of credit in form and substance satisfactory to Landlord and from a financial institution satisfactory to Landlord in the original amount of $125,581.52 (the “Letter of Credit”).

(b) If no default with respect to the payment of Fixed Rent or recurring additional rent shall have previously occurred and if Tenant shall not then be in default beyond applicable notice and grace periods on the applicable reduction date with respect to any obligation under this Lease, then Tenant shall be permitted to reduce the amount of the Letter Credit (i) on the date twelve (12) months after the Rent Commencement Date to $94,186.14, and (ii) on the date thirty (30) month after the Rent Commencement Date to $62,790.76

(c) The Letter of Credit may be drawn from time to time by Landlord upon Tenant’s default of its obligations under this Lease or if the Letter of Credit is about to expire and has not been renewed within thirty (30) days preceding such expiration. Should Landlord draw down the Letter of Credit, Tenant shall be obligated to restore it to its original amount.

ARTICLE IX

RIGHTS OF PARTIES HOLDING PRIOR INTERESTS

9.1	Lease Subordinate

This Lease shall be subject and subordinate to any mortgage now or hereafter on the Property, and to each advance made or hereafter to be made under any mortgage, and to all renewals, modifications, consolidation, replacements and extensions thereof and all substitutions therefor. Landlord shall use commercially reasonable efforts to obtain from the holder thereof a commercially reasonable subordination, non-disturbance agreement with Tenant in such holder’s standard form by the terms of which such holder will agree to recognize the rights of Tenant under this Lease and to accept Tenant as tenant of the Premises under the terms and conditions of this Lease in the event of acquisition of title by such holder through foreclosure proceedings or otherwise and Tenant will agree to recognize and attorn to the holder of such mortgage as Landlord in such event, which agreement shall be made expressly to bind and inure to the benefit of the successors and assigns of Tenant and of the holder and upon anyone purchasing the

- 27 -

Premises at any foreclosure sale. Notwithstanding the foregoing, any such holder may at its election subordinate its mortgage to this Lease without the consent or approval of Tenant. Tenant agrees to execute and deliver any appropriate instruments containing commercially reasonable terms and provisions necessary to carry out the agreements contained in this Section 9.1.

9.2	Rights of Holder of Mortgage to Notice of Defaults by Landlord and to Cure Same

No act or failure to act on the part of Landlord which would entitle Tenant under the terms of this Lease, or by law, to be relieved of Tenant’s obligations hereunder or to terminate this Lease, shall result in a release or termination of such obligations or a termination of this Lease unless (i) Tenant shall have first given written notice of Landlord’s act or failure to act to Landlord’s mortgagees of which Tenant received notice and an address to send notices, if any, specifying the act or failure to act on the part of Landlord which could or would give basis to Tenant’s rights; and (ii) such mortgagees after receipt of such notice, have failed or refused to correct or cure the condition complained of within thirty (30) days after such notice or if not capable of cure within thirty (30) days, within a reasonable time not to exceed ninety days (90) days; but nothing contained in this Section 9.2 shall be deemed to impose any obligation on any such mortgagees to correct or cure any condition.

EXHIBIT C

Work Letter

1. Landlord’s Work. This Exhibit C sets forth the obligations of Landlord and Tenant with respect to the initial improvements to be performed in the Premises to prepare the same for Tenant’s use and occupancy. Landlord shall provide a “turn-key” renovation of the Premises and construct the initial improvements as shown on the Plans (as defined below) in accordance with the terms of this Exhibit C (“Landlord’s Work”).

2. Plans. The parties have approved final architectural, electrical and mechanical construction drawings referenced in the drawing set prepared by ▇▇▇▇▇▇▇ & Caulfield Associates, Inc., as Project #2013.146, dated May 28, 2013 (the “Plans”). In the event that the building department or any other governmental or quasi-governmental agency, board or authority requires any modifications to the Plans, Landlord and Tenant agree to cooperate and work expeditiously to modify and re-submit the Plans for any necessary approvals. Approval by Landlord of Landlord’s Work and the Plans shall not constitute any warranty by Landlord to Tenant of the adequacy of the design for Tenant’s intended use of the Premises.

3. Performance of Landlord’s Work. Except as hereinafter provided to the contrary, Landlord shall perform Landlord’s Work shown on the Plans using building standard materials and quantities as determined by Landlord (“Building Standards”).

4. Substantial Completion. Landlord shall use commercially reasonable efforts to cause Landlord’s Work to be Substantially Completed (as defined in Section 3.2 of the Lease), subject to delays caused by Force Majeure (as defined below) and Tenant Delays (as defined in Paragraph 6 below), on or before August 1, 2013 (the “Anticipated Substantial Completion Date”). If Landlord’s Work is not Substantially Completed on or before the Anticipated Substantial Completion Date for any reason, the Lease shall remain in full force and effect; provided that the Commencement Date shall not occur until Landlord’s Work is Substantially Completed, except in the case of Tenant Delay, pursuant to Paragraph 5 below. In the event that Landlord’s Work is not Substantially Completed on or before September 30, 2013 (which date shall be extended on a day-for-day basis for Force Majeure and Tenant Delay), Tenant shall have the right, prior to the time Landlord’s Work is Substantially Completed, to terminate this Lease by providing written notice of such termination to Landlord. “Force Majeure” shall mean events beyond Landlord’s reasonable control, including, without limitation, accident; breakage; strike, lockout; act of terrorism; shortage of materials, which shortage is not unique to Landlord; governmental regulation, moratorium or other governmental action, inaction or delay; or fire, flood, unusually inclement weather, earthquake or other natural disaster.

5. Tenant Delays. In the event that Landlord’s Work is not Substantially Completed by the Anticipated Substantial Completion Date by reason of any delay attributable to Tenant (a “Tenant Delay”), then, in such event, the Commencement Date shall be deemed to be the date that Substantial Completion would have occurred but for such Tenant Delay. A Tenant Delay shall include, without limitation, any of the following:

(i)

the failure of Tenant to furnish in a timely manner all information and approvals necessary to complete the plans, drawings, specifications, finish details or the other information required under Paragraph 2 above;

C-1

(ii)

Tenant’s requirements for special work or materials, finishes, or installations other than the Building Standards or Tenant’s request for any Additional Work;

(iii)

the performance of any other work in the Premises by any person, firm or corporation employed by or on behalf of Tenant, or any failure to complete or delay in completion of such work (including, without limitation, installation of Tenant’s furniture); or

(iv)

any other act or omission of Tenant.

6. Additional Work. If Tenant shall request any change, addition or alteration in any of the Plans (the “Additional Work”), Landlord shall have such revisions to the drawings prepared at Tenant’s cost and Tenant shall reimburse Landlord within ten (10) days of demand for the reasonable cost thereof, plus any applicable state sales or use tax thereon. Promptly upon completion of the revisions, Landlord shall notify Tenant in writing of the increased cost to Landlord’s Work, if any, which will be chargeable to Tenant by reason of such Additional Work. Tenant, within three (3) business days, shall notify Landlord in writing (the “Additional Work Notice”) whether it desires to proceed with such Additional Work, provided that Tenant shall pay for any additional cost resulting from any delay in the Landlord’s Work during such time period. Landlord shall not perform any Additional Work unless and until it receives an Additional Work Notice from Tenant approving the same. In the absence of an Additional Work Notice approving such Additional Work, Landlord shall have the option to continue work on the Premises disregarding the requested Additional Work, or, after giving Tenant three (3) business days notice, Landlord may elect to discontinue work on the Premises until it receives notice of Tenant’s decision, in which event Tenant shall be responsible for any delay in Landlord’s Work resulting therefrom.

7. Tenant Access. Landlord, upon request by Tenant, shall grant to Tenant and Tenant’s agents a license to enter the Premises at any time from and after the date which Landlord reasonably determines to be thirty (30) days prior to the date Landlord’s Work will be Substantially Completed for the purposes of installing Tenant’s cabling in the Premises and completing other work on Tenant’s behalf in accordance with the terms and provisions of this paragraph 7; provided, however, that such work shall not interfere with Landlord’s Work. It shall be a condition to the grant by Landlord and continued effectiveness of such license that:

(a) Tenant’s request for such early access shall be accompanied by: (i) a description of and schedule for the work to be performed by those persons and entities for whom such access is being requested; (ii) the names and addresses of all contractors for whom such early access is being requested and copies of all licenses and permits required in connection with the performance of the work for which such access is being requested; and (iii) certificates of insurance (in amounts and with insured parties satisfactory to Landlord). All of the foregoing shall be subject to Landlord’s approval in its sole discretion.

C-2

(b) Such early access for installation purposes shall be subject to reasonable scheduling by Landlord.

(c) Tenant’s agents, contractors, workmen, mechanics, suppliers and invitees shall work in harmony and not interfere with (i) Landlord and Landlord’s agents in performing Landlord’s Work or any Additional Work in the Premises or work by Landlord or its agents in other premises or common areas of the Building, or (ii) the general operation of the Building. If at any time such entry shall cause or reasonably threaten to cause such disharmony or interference, Landlord may withdraw such license upon twenty-four (24) hours’ prior written notice to Tenant.

Any such entry into and occupation of the Premises by Tenant shall be deemed to be under all of the terms, covenants, conditions and provisions of the Lease (including, without limitation, the insurance and indemnity provisions), excluding only the covenant to pay Fixed Rent, additional rent and electricity; provided, however, that, notwithstanding the foregoing, Tenant’s obligation to pay Fixed Rent, additional rent and electricity hereunder shall commence upon Tenant conducting any business at the Premises. Landlord shall not be liable for any injury, loss or damage which may occur to any of Tenant’s work or installations made in the Premises or to property placed therein prior to the commencement of the Term, the same being at Tenant’s sole risk and liability. Tenant shall be liable to Landlord for any damage to the Premises or to any portion of Landlord’s Work caused by Tenant or any of Tenant’s employees, agents, contractors, workmen or suppliers. In the event the performance of the work by Tenant, its agents, employees or contractors causes material extra costs to Landlord, Tenant shall reimburse Landlord for the entire extra cost and the cost incurred by Landlord for the engineers or operators under applicable union regulations or contracts.

8. Incorporation. The terms and provisions of the Lease, insofar as they are applicable to this Work Letter, are hereby incorporated herein by reference.

9. Additional Rent. All amounts payable by Tenant to Landlord hereunder shall be deemed to be Rent under the Lease and upon any default in the payment of same, Landlord shall have all of the rights and remedies provided for in the Lease.

10. Limitation. This Exhibit shall not be deemed applicable to any additional space added to the Premises at any time or from time to time, whether by any options under the Lease or otherwise, or to any portion of the original Premises or any additions to the Premises in the event of a renewal or extension of the original Term of the Lease, whether by any options under the Lease or otherwise, unless expressly so provided in the Lease or any amendment or supplement to the Lease.
