Premises and Term

2.1 Premises. Landlord hereby leases to Tenant and Tenant hereby leases from Landlord, subject to and with the benefit of the terms, covenants, conditions and provisions of this Lease, the Premises, excluding the roof, exterior faces of exterior walls, the common stairways, and pipes, ducts, conduits, wires, and appurtenant fixtures serving exclusively or in common other parts of the Building (and any areas, such as the space above the ceiling or in the walls, that may contain such pipes, ducts, conduits, wires or appurtenant fixtures), and if Tenant’s space includes less than entire rentable area of any floor, excluding the central core area of such floor.

Tenant shall have, as appurtenant to the Premises, rights to use, in common for lease years 1-3 and exclusively for lease years 4-5, subject to reasonable rules of general applicability to tenants of the Building from time to time made by Landlord of which Tenant is given notice: (a) the common lobbies, hallways and stairways of the Building, (b) common walkways and driveways necessary for access to the Building, (c) the common parking areas serving the Building, (d) the loading dock serving the Building, and (e) if the Premises include less than the entire rentable area of any floor, the common toilets and other common facilities in the central core area of such floor. Tenant shall further have the right to use the space above the suspended ceiling in order for Tenant to install its conduits, cables and pipes, provided said installation is done in compliance with all applicable codes, regulations, ordinances and/or laws and pursuant to the terms and conditions of subsection 6.2.5 of this Lease (it being further agreed by Tenant that said installations shall not constitute “nonstructural, interior installations or alterations” as set forth in subsection 6.2.5 (b)).

There are approximately 76 parking spaces serving the Building. Tenant shall be permitted to use its proportionate share of said available parking. Subject to the actions of and/or directives or orders from governmental and other authorities, and/or the actions of utility companies, Landlord shall not decrease the size of the existing parking area serving the Building.

Landlord reserves the right from time to time, upon reasonable prior notice to Tenant, except in the case of emergencies, and without unreasonable interference with use of the Premises: (a) to install, use, maintain, repair, replace and relocate for service to the Premises and other parts of the Building, or either, pipes, ducts, conduits, wires and appurtenant fixtures, wherever located in the Premises or Building, (b) to alter or relocate any other common facility, (c) to make any repairs and replacements to the Premises which Landlord may deem necessary, and (d) in connection with any excavation made upon adjacent land of Landlord or others, to enter, and to license others to enter, upon the Premises to do such work as the person causing such excavation deems necessary to preserve the wall of the Building from injury or damage and to support the same.

6

Landlord shall use reasonable efforts to perform the activities permitted under this paragraph during normal business hours.

2.2 Term. TO HAVE AND TO HOLD for a term beginning on the Commencement Date, and ending on the Expiration Date, unless sooner terminated as hereinafter provided. When the dates of the beginning and end of the term have been determined, such dates shall be evidenced by a document, in the form attached hereto as Exhibit B, which Landlord shall complete and deliver to Tenant, and which shall be deemed conclusive unless Tenant shall notify Landlord of any disagreement therewith within ten (10) business days of receipt.

The term “lease year” as used herein shall mean a period of twelve (12) consecutive full calendar months. The first lease year shall begin on the Commencement Date if the Commencement Date is the first day of a calendar month; if not, then the first lease year shall commence upon the first day of the calendar month next following the Commencement Date. Each succeeding lease year shall commence upon the anniversary date of the first lease year.

2.3 Extension Option. Subject to the terms and conditions contained herein, Tenant shall have the right to extend the term of this Lease for one additional period of three (3) years, to begin immediately upon the expiration of the original term of this Lease (the “extended term”), provided that each of the following conditions has been satisfied: (i) as of the date of the Tenant’s Notice of Intent (as defined below), the Landlord’s Notice of the Market Rate (as defined below), the Date of Tenant’s Acceptance (as defined below), and as of the commencement of the extended term, Tenant shall not be in default and shall not have previously been in default of its obligations under this Lease beyond any applicable grace period; (ii) Tenant shall have a net income for the 12-month period immediately preceding the date of the Extension Notice and for the 12-month period immediately preceding the commencement of the extended term; and (iii) simultaneously with delivery of the Extension Notice and also at the commencement of the extended term, Tenant shall have delivered to Landlord an audited statement prepared using generally accepted accounting principles evidencing such net income during each of the periods specified in clause (ii) hereinabove. If an audited statement has not yet been prepared for either of the 12-month periods specified in (ii) above, Tenant shall deliver, in lieu thereof, a financial statement certified by an officer of the company and prepared using generally accepted accounting principles to evidence said net income, provided, however, Tenant shall deliver said audited statement to Landlord immediately upon its completion and if said audited statement does not corroborate the certified financial statement, Landlord shall have the right to terminate the extended term and any extension notice delivered by Tenant shall be deemed null and void and of no further effect as between the parties. Landlord shall not be liable to Tenant for any damages (direct, indirect, punitive, consequential, special or otherwise) incurred by Tenant in connection with any failure of the term of this Lease to be extended hereunder. All of the terms, covenants and provisions of this Lease shall apply to such extended term except that the Annual Fixed Rent Rate for such extension period shall be the market rate at the commencement of such extended term, as designated by Landlord. The “market rate” shall be the annual fair market rental rate during the extended term, for leases, for a space of similar size to

7

the Premises and of a quality comparable to the Premises, in a comparable market as reasonably determined by Landlord. In order for Tenant’s right to extend the term of this Lease to be effective, Tenant shall notify Landlord in writing of its desire to extend the term no later than June 15, 2007 (the “Tenant’s Notice of Intent”). If Tenant delivers the Tenant’s Notice of Intent as aforesaid, then, not later than July 5, 2007, Landlord shall give written notice to Tenant of Landlord’s designation of the market rate (the “Landlord’s Notice of the Market Rate”). Tenant shall either accept or reject in writing Landlord’s designation of the market rate no later than July 15, 2007 (in the event Tenant accepts Landlord’s designation, the date of Tenant’s acceptance is referred to herein as the “Date of Tenant’s Acceptance”). Any failure on the part of Tenant to deliver, or any act or omission by Tenant not to deliver, its notice accepting or rejecting the Landlord’s designation of the market rate shall bind Tenant to Landlord’s designation of the market rate and the extension of this Lease shall automatically be effected without the execution of any additional documents. If Tenant accepts the Landlord’s designation of the market rate, the extension of this Lease shall be automatically effected without the execution of any additional documents. If Tenant fails or decides not to timely deliver its Notice of Intent, or rejects Landlord’s designation of the market rate, as aforesaid, Tenant shall be deemed to have waived its right to extend the term of the Lease hereunder. The original term and the extended term are hereinafter collectively called the “term”.

In any event, the Annual Fixed Rent Rate for the extended term shall not be less than the Annual Fixed Rent Rate in effect immediately prior to such extended term.

ARTICLE 3

Improvements

3.1 Condition of Premises. The Premises are leased to Tenant “as-is” in the condition the Premises are in as of the date hereof without any representations or warranties by Landlord as to the condition or suitability of the Premises for Tenant’s use, and without any obligation by Landlord to construct or prepare the Premises for Tenant’s use or occupancy.

3.2 Tenant’s Work. Promptly following the Commencement Date, Tenant shall perform with reasonable dispatch, at Tenant’s sole cost and expense (except for reimbursement by Landlord of the Allowance as hereinafter provided), all work which is necessary or desirable to prepare the Premises for Tenant’s use and occupancy (the “Tenant’s Work”) in accordance with plans and specifications submitted to and approved in advance in writing by Landlord in each instance. Tenant shall be responsible, at its sole cost and expense, for the preparation of the architectural, electrical and mechanical construction drawings, plans and specifications (called the “construction plans”) which are necessary to perform the Tenant’s Work, which construction plans shall be submitted to Landlord for prior approval. If any of such construction plans are disapproved by Landlord, Landlord shall provide Tenant with specific reasons for such disapproval and the foregoing submission process shall be repeated until all construction plans have been approved by Landlord. Landlord’s approval in each instance shall not be unreasonably withheld, conditioned or delayed for any construction plans (i) which would not involve

8

or affect any structural or exterior element of the Building or any portion thereof, (ii) which would not adversely affect the value of the Building or any portion thereof, (iii) which would not adversely affect the proper functioning of the Building systems or other facilities, or (iv) which would not change the character of the exterior or interior architectural design of the Building. During the performance of Tenant’s Work, Tenant shall not be obligated to pay Fixed Rent, Taxes or Operating Costs to Landlord unless the Rent Commencement Date has occurred. However, Tenant shall reimburse Landlord for its actual costs incurred in connection with the Tenant’s Work, including, without limitation, trash removal, electrical costs and costs of other utilities during construction (if separate accounts have not been established in Tenant’s name with the local utility companies at such time). All Tenant’s Work shall be performed in a good and workmanlike manner employing materials of good quality and so as to conform with all applicable zoning, building, fire, health and other codes, regulations, ordinances and laws and shall be subject to the applicable provisions of this Lease, including, without limitation, subsection 6.2.5. Tenant shall use, as its project manager Nordblom Development Company (pursuant to a separate written agreement between Nordblom Development Company and Tenant)

3.3 Allowance. Landlord shall provide Tenant with an allowance of up to $200,000.00 (the “Allowance”) to be used towards the cost of Tenant’s Work (including the design fees of Tenant’s architects and engineers). When Tenant has incurred costs for the Tenant’s Work, Tenant shall submit to Landlord from time to time (but no more frequently than monthly) requisitions for payment setting forth any costs incurred for Tenant’s Work, together with waivers of lien from all contractors and subcontractors, invoices from contractors, subcontractors and suppliers, and other reasonable documentation evidencing the costs, including fees of architects and engineers, incurred by Tenant for Tenant’s Work, to the reasonable satisfaction of Landlord. Landlord shall, within thirty (30) days following Landlord’s receipt thereof, pay to Tenant ninety (90%) percent of the amount of each such requisition (or of such lesser amount as is approved by Landlord) with ten (10%) percent to be retained. Such payments, in the aggregate, shall not exceed an amount equal to ninety (90%) percent of the Allowance. Landlord shall pay to Tenant the ten (10%) percent retained as aforesaid within thirty (30) days following the submission by Tenant of a written statement from Tenant’s architect or engineer that Tenant’s Work has been completed in accordance with the approved construction plans, a final lien waiver executed by Tenant’s general contractor, and a final certificate of occupancy for, and any other required governmental approvals of, Tenant’s Work. The costs of Tenant’s Work shall include all costs incurred by Tenant for construction and installation of improvements (but excluding any trade fixtures or personal property), including the costs of all labor and materials, and all contractor’s fees. Tenant shall be responsible for paying for all costs of Tenant’s Work not included in the Allowance and for all costs in excess of the Allowance. Tenant shall not be entitled to any rent credit or refund for any unused portion of the Allowance.

ARTICLE 4

Rent

4.1 The Fixed Rent. Commencing on the Rent Commencement Date, Tenant covenants and agrees to pay rent to Landlord at the Original Address of Landlord or at such other place or to such other person or entity as Landlord may by notice in writing to Tenant from time to time direct, at the Annual Fixed Rent Rate, in equal installments at the Monthly Fixed Rent Rate (which is 1/12th of the Annual Fixed Rent Rate), in advance, on the first day of each calendar month included in the term; and for any portion of a calendar month following the Rent Commencement Date, at the rate for the first lease year payable in advance for such portion.

If Landlord shall give notice to Tenant that all rent and other payments due hereunder are to be made to Landlord by electronic funds transfers, so called, or by similar means, Tenant shall make all such payments as shall be due after receipt of said notice by means of said electronic funds transfers (or such similar means as designated by Landlord), provided, however, that Tenant shall have the right to suspend such electronic funds transfers for just cause for a reasonable period of time, which cause and period of time must be consented to by Landlord (which consent shall not be unreasonably withheld or delayed).

4.2 Additional Rent. Tenant covenants and agrees to pay, as Additional Rent, insurance costs, utility charges, personal property taxes and its pro rata share of taxes and operating costs with respect to the Premises as provided in this Section 4.2 as follows:

4.2.1 Real Estate Taxes. Tenant shall pay to Landlord, as additional rent, for each tax period partially or wholly included in the term, Tenant’s Percentage of Taxes (as hereinafter defined). Tenant shall remit to Landlord, on the first day of each calendar month, estimated payments on account of Taxes, such monthly amounts to be sufficient to provide Landlord, by the time real estate tax payments are due and payable to any governmental authority responsible for collection of same, a sum equal to the Tenant’s Percentage of Taxes, as reasonably estimated by Landlord from time to time on the basis of the most recent tax data available. The initial calculation of the monthly estimated payments shall be based upon the Initial Estimate of Tenant’s Percentage of Taxes for the Tax Year and upon quarterly payments being due to the governmental authority on August 1, November 1, February 1 and May 1, and shall be made when the Commencement Date has been determined. If the total of such monthly remittances for any Tax Year is greater than the Tenant’s Percentage of Taxes for such Tax year, Landlord shall promptly pay to Tenant, or credit against the next accruing payments to be made by Tenant pursuant to this subsection 4.2.1, the difference; if the total of such remittances is less than the Tenant’s Percentage of Taxes for such Tax Year, Tenant shall pay the difference to Landlord at least ten (10) days prior to the date or dates within such Tax Year that any Taxes become due and payable to the governmental authority (but in any event no earlier than ten (10) days following a

10

written notice to Tenant, which notice shall set forth the manner of computation of Tenant’s Percentage of Taxes).

If, after Tenant shall have made reimbursement to Landlord pursuant to this subsection 4.2.1, Landlord shall receive a refund of any portion of Taxes paid by Tenant with respect to any Tax Year during the term hereof as a result of an abatement of such Taxes by legal proceedings, settlement or otherwise (without either party having any obligation to undertake any such proceedings), Landlord shall promptly pay to Tenant, or credit against the next accruing payments to be made by Tenant pursuant to this subsection 4.2.1, the Tenant’s Percentage of the refund (less the proportional, pro rata expenses, including attorneys’ fees and appraisers’ fees, incurred in connection with obtaining any such refund), as relates to Taxes paid by Tenant to Landlord with respect to any Tax Year for which such refund is obtained. If Landlord does not pursue a tax abatement during the Tax Year in question, Tenant shall have the right to do so in Landlord’s name and Landlord shall reasonably cooperate with Tenant in such effort, provided however, that Tenant shall give prior written notice to Landlord that Tenant elects to seek an abatement and provided, further, that all abatement proceedings are entirely at Tenant’s sole cost and expense.

In the event this Lease shall commence, or shall end (by reason of expiration of the term or earlier termination pursuant to the provisions hereof), on any date other than the first or last day of the Tax Year, or should the Tax Year or period of assessment of real estate taxes be changed or be more or less than one (1) year, as the case may be, then the amount of Taxes which may be payable by Tenant as provided in this subsection 4.2.1 shall be appropriately apportioned and adjusted.

The term “Taxes” shall mean all taxes, assessments, betterments and other charges and impositions (including, but not limited to, fire protection service fees and similar charges) levied, assessed or imposed at any time during the term by any governmental authority upon or against the Property, or taxes in lieu thereof, and additional types of taxes to supplement real estate taxes due to legal limits imposed thereon. If, at any time during the term of this Lease, any tax or excise on rents or other taxes, however described, are levied or assessed against Landlord with respect to the rent reserved hereunder, either wholly or partially in substitution for, or in addition to, real estate taxes assessed or levied on the Property, such tax or excise on rents shall be included in Taxes; however, Taxes shall not include franchise, corporation, estate, inheritance, succession, capital levy, transfer, gift, income or excess profits taxes assessed on Landlord, or penalties for delinquent payment of Taxes assessed against Landlord provided that such late payment is not caused by or a result of any acts or omissions of Tenant. Taxes shall include any estimated payment made by Landlord on account of a fiscal tax period for which the actual and final amount of taxes for such period has not been determined by the governmental authority as of the date of any such estimated payment.

11

4.2.2  Personal Property Taxes. Tenant shall pay all taxes charged, assessed or imposed upon the personal property of Tenant in or upon the Premises.

4.2.3  Operating Costs. Tenant shall pay to Landlord the Tenant’s Percentage of Operating Costs (as hereinafter defined) incurred by Landlord in any calendar year. Tenant shall remit to Landlord, on the first day of each calendar month, estimated payments on account of Operating Costs, such monthly amounts to be sufficient to provide Landlord, by the end of the calendar year, a sum equal to the Operating Costs, as reasonably estimated by Landlord from time to time. The initial monthly estimated payments shall be in an amount equal to 1/12th of the Initial Estimate of Tenant’s Percentage of Operating Costs for the Calendar Year. If, at the expiration of the year in respect of which monthly installments of Operating Costs shall have been made as aforesaid, the total of such monthly remittances is greater than the actual Operating Costs for such year, Landlord shall promptly pay to Tenant, or credit against the next accruing payments to be made by Tenant pursuant to this subsection 4.2.3, the difference; if the total of such remittances is less than the Operating Costs for such year, Tenant shall pay the difference to Landlord within twenty (20) days from the date Landlord shall furnish to Tenant an itemized statement of the Operating Costs, prepared, allocated and computed in accordance with generally accepted accounting principles. Any reimbursement for Operating Costs due and payable by Tenant with respect to periods of less than twelve (12) months shall be equitably prorated.

The term “Operating Costs” shall mean all costs and expenses incurred for the operation, maintenance, repair, upkeep and exterior cleaning of the Property, and the portion of such costs and expenses with regard to the common areas, facilities and amenities of the Park which is equitably allocable to the Property, including, without limitation, all costs of maintaining and repairing the Property and the Park (including snow removal, landscaping and grounds maintenance, operation and maintenance of parking lots, sidewalks, walking paths, access roads and driveways, security, operation and repair of heating and air-conditioning equipment, elevators, lighting and any other Building equipment or systems) and of all repairs and replacements (other than repairs or replacements for which Landlord has received full reimbursement from contractors, other tenants of the Building or from others) necessary to keep the Property and the Park in good working order, repair, appearance and condition; all costs, including material and equipment costs, for cleaning the exterior of the Building (including without limitation window cleaning of the Building); all costs of any reasonable insurance carried by Landlord relating to the Property; all costs related to provision of heat (including oil, electric, steam and/or gas), air-conditioning, and water (including sewer charges) and other utilities to the Building (exclusive of reimbursement to Landlord for any of same received as a result of direct billing to any tenant of the Building); payments under all service contracts relating to the foregoing; all compensation, fringe benefits, payroll taxes and workmen’s compensation insurance premiums related thereto with respect to any employees of Landlord or its affiliates engaged in security and maintenance of the Property and the Park;

12

attorneys’ fees and disbursements (exclusive of any such fees and disbursements incurred in tax abatement proceedings or the preparation of leases) and auditing and other professional fees and expenses; and a management fee.

There shall not be included in such Operating Costs: (a) brokerage fees (including rental fees) related to the operation of the Building; (b) interest and depreciation charges incurred on the Property; (c) expenditures made by Tenant with respect to (i) janitorial type cleaning, maintenance and upkeep of the interior of the Premises (provided said janitorial and cleaning services are not being provided by Landlord), and (ii) the provision of electricity to the Premises; (d) the cost of any item for which Landlord is reimbursed by insurance proceeds; (e) payments which exceed arms-length competitive market prices for services rendered to the Premises paid to any person, firm or corporation affiliated with Landlord to the extent that the payments for such services exceed the competitive costs that would have been paid to parties unaffiliated with Landlord; (f) costs incurred by Landlord due to a breach by Landlord of the terms and conditions of this Lease but only to the extent such costs do not arise from or are attributable to the acts or omissions of Tenant; (g) costs of correcting defects in the original construction of the Premises; (h) costs resulting from the gross negligence or willful misconduct of Landlord or Landlord’s agents; (i) legal fees incurred in tenant disputes, including litigation and arbitration, to the extent said fees are not related to the operation and/or maintenance of the Building, and/or are not related to the relationship (contractual or otherwise) which exists or may exist between Landlord and Tenant; and (j) costs or expenses related to the removal, abatement or remediation of hazardous materials in or about the Building and/or the Property which is existing as of the date hereof, to the extent said costs or expenses are not attributable to or arise from the acts or omission of Tenant or Tenant’s agents, employees, invitees, servants or contractors (which costs and expenses shall be paid for by Tenant).

If, during the term of this Lease, Landlord shall replace any capital items or make any capital expenditures (collectively called “capital expenditures”) the total amount of which is not properly included in Operating Costs for the calendar year in which they were made, there shall nevertheless be included in Operating Costs for each calendar year in which and after such capital expenditure is made the annual charge-off of such capital expenditure. (Annual charge-off shall be determined by (i) dividing the original cost of the capital expenditure by the number of years of useful life thereof [The useful life shall be reasonably determined by Landlord in accordance with generally accepted accounting principles and practices in effect at the time of acquisition of the capital item.]; and (ii) adding to such quotient an interest factor computed on the unamortized balance of such capital expenditure based upon an interest rate reasonably determined by Landlord as being the interest rate then being charged for long-term mortgages by institutional lenders on like properties within the locality in which the Building is located.) Provided, further, that if Landlord reasonably concludes on the basis of engineering estimates that a particular capital expenditure will effect savings in Operating Costs and that such annual projected

13

savings to Operating Costs will exceed the annual charge-off of capital expenditure computed as aforesaid, then and in such events, if Landlord shall make such capital expenditure, the annual charge-off shall be determined by dividing the amount of such capital expenditure by the number of years over which the projected amount of such savings shall fully amortize the cost of such capital item or the amount of such capital expenditure; and by adding the interest factor, as aforesaid.

If during any portion of any year for which Operating Costs are being computed, the Building was not fully occupied by tenants or if not all of such tenants were paying fixed rent or if Landlord was not supplying all tenants with the services being supplied hereunder, the variable components of actual Operating Costs incurred shall be reasonably extrapolated by Landlord to the estimated Operating Costs that would have been incurred if the Building were fully occupied by tenants and all such tenants were then paying fixed rent or if such services were being supplied to all tenants, and such extrapolated amount shall, for the purposes of this Section 4.2.3, be deemed to be the Operating Costs for such year.

Subject to Article 7 of the Lease, Tenant shall have the right to obligate Landlord to replace the roof of the Building provided Tenant delivers to Landlord evidence reasonably satisfactory to Landlord that the replacement of the roof will result in an actual decrease in Operating Costs (the “Roof Replacement Evidence”). All costs associated with the replacement of the roof shall be treated as a capital expenditure under this subsection 4.2.3. Notwithstanding the foregoing, Landlord shall not in its sole discretion be obligated to replace the roof of the Building as aforesaid during the last twelve (12) months of the term, provided, however, if Tenant delivers the Roof Replacement Evidence during the last twelve (12) months of the term, Landlord shall be responsible for the amount of the differential, if any, between the amortized cost of replacing the roof (as determined pursuant to this subsection 4.2.3) and the cost of Landlord’s maintenance of the roof during the last twelve (12) months of the term as determined from the date reasonably satisfactory Roof Replacement Evidence as aforesaid is delivered to Landlord through the end of the term.

4.2.4  Insurance. Tenant shall, at its expense, as Additional Rent, take out and maintain throughout the term the following insurance protecting Landlord:

4.2.4.1  Commercial general liability insurance naming Landlord, Tenant, and Landlord’s managing agent and any mortgagee of which Tenant has been given notice as insureds or additional insureds and indemnifying the parties so named against all claims and demands for death or any injury to person or damage to property which may be claimed to have occurred on the Premises (or the Property, insofar as used by customers, employees, servants or invitees of the Tenant), in amounts which shall, at the beginning of the term, be at least equal to the limits set forth in Section 1.1, and, which, from time to time during the term, shall be for such higher limits, if any, as are customarily carried in the area in which the Premises

14

are located on property similar to the Premises and used for similar purposes; and workmen’s compensation insurance with statutory limits covering all of Tenant’s employees working on the Premises.

4.2.4.2  Fire insurance with the usual extended coverage endorsements covering all Tenant’s furniture, furnishings, fixtures, equipment and any and all improvements or alterations installed by or on behalf of Tenant, but excluding the Tenant’s Work.

4.2.4.3  All such policies shall be obtained from responsible companies qualified to do business and in good standing in Massachusetts, which companies and the amount of insurance allocated thereto shall be subject to Landlord’s approval. Tenant agrees to furnish Landlord with certificates evidencing all such insurance prior to the beginning of the term hereof and evidencing renewal thereof at least thirty (30) days prior to the expiration of any such policy. Each such policy shall be non-cancelable with respect to the interest of Landlord without at least ten (10) days’ prior written notice thereto. In the event provision for any such insurance is to be by a blanket insurance policy, the policy shall allocate a specific and sufficient amount of coverage to the Premises.

4.2.4.4  All insurance which is carried by either party with respect to the Building, Premises or to furniture, furnishings, fixtures, or equipment therein or alterations or improvements thereto, whether or not required, shall include provisions which either designate the other party as one of the insured or deny to the insurer acquisition by subrogation of rights of recovery against the other party to the extent such rights have been waived by the insured party prior to occurrence of loss or injury, insofar as, and to the extent that, such provisions may be effective without making it impossible to obtain insurance coverage from responsible companies qualified to do business in the state in which the Premises are located (even though extra premium may result therefrom). In the event that extra premium is payable by either party as a result of this provision, the other party shall reimburse the party paying such premium the amount of such extra premium. If at the request of one party, this non-subrogation provision is waived, then the obligation of reimbursement shall cease for such period of time as such waiver shall be effective, but nothing contained in this subsection shall derogate from or otherwise affect releases elsewhere herein contained of either party for claims. Each party shall be entitled to have certificates of any policies containing such provisions. Each party hereby waives all rights of recovery against the other for loss or injury against which the waiving party is protected by insurance containing said provisions, reserving, however, any rights with respect to any excess of loss or injury over the amount recovered by such insurance. Tenant shall not acquire as insured under any insurance carried on the Premises any right to participate in the adjustment of loss or to receive insurance proceeds and agrees upon request promptly to endorse and deliver to

15

Landlord any checks or other instruments in payment of loss in which Tenant is named as payee.

4.2.5  Utilities. Tenant shall pay all charges made by public authority or utility for the cost of electricity furnished or consumed on the Property, all charges for any utilities supplied by Landlord to the Property pursuant to Subsection 5.1.1, and all charges for telephone and other utilities or services not supplied by Landlord pursuant to Subsection 5.1.1, whether designated as a charge, tax, assessment, fee or otherwise, all such charges to be paid as the same from time to time become due. Except as otherwise provided in Article 5, it is understood and agreed that Tenant shall make its own arrangements for the installation or provision of all such utilities and that Landlord shall be under no obligation to furnish any utilities to the Premises and shall not be liable for any interruption or failure in the supply of any such utilities to the Premises.

4.3 Late Payment of Rent. If any installment of rent is paid after the date the same was due, and if on a prior occasion in the twelve (12) month period prior to the date such installment was due an installment of rent was paid after the same was due, then Tenant shall pay Landlord a late payment fee equal to five (5%) percent of the overdue payment.

4.4 Security and Restoration Deposit. Upon the execution of this Lease, Tenant shall deposit with Landlord the Security and Restoration Deposit. Upon the second anniversary of the lease term, Tenant shall deposit with Landlord an additional security and restoration deposit equal to twenty-five thousand ($25,000.00) dollars, which additional deposit shall be added to and become a part of the Security and Restoration Deposit. Said deposit shall be held by Landlord as security for the faithful performance by Tenant of all the terms of this Lease by said Tenant to be observed and performed. The security deposit shall not be mortgaged, assigned, transferred or encumbered by Tenant without the written consent of Landlord and any such act on the part of Tenant shall be without force and effect and shall not be binding upon Landlord.

If the Fixed Rent or Additional Rent or any other sum payable hereunder shall be overdue and unpaid or should Landlord make payments on behalf of the Tenant, or Tenant shall fail to perform any of the terms of this Lease, then Landlord may, at its option and without prejudice to any other remedy which Landlord may have on account thereof, appropriate and apply said entire deposit or so much thereof as may be necessary to compensate Landlord toward the payment of Fixed Rent, Additional Rent or other sums or loss or damage sustained by Landlord due to such breach on the part of Tenant; and Tenant shall forthwith upon demand restore said security to the original sum deposited. Should Tenant comply with all of said terms and promptly pay all of the rentals as they fall due and all other sums payable by Tenant to Landlord, said deposit shall be returned in full to Tenant at the end of the term.

In the event of bankruptcy or other creditor-debtor proceedings against Tenant, all securities shall be deemed to be applied first to the payment of rent and other charges due Landlord for all periods prior to the filing of such proceedings.

18

contributes to the release or threat of release of Hazardous Materials, or (iii) to any claim brought or liability imposed under any law, regulation or ordinance, or common law, arising out of any personal injury or damage suffered or alleged to have been suffered by Tenant’s employees, agents, invitees or contractors.

22

voluntarily, involuntarily or by operation of law, or permit the occupancy of the Premises by anyone other than Tenant without the prior written consent of Landlord. In the event Tenant desires to assign this Lease or sublet any portion or all of the Premises, Tenant shall notify Landlord in writing of Tenant’s intent to so assign this Lease or sublet the Premises and the proposed effective date of such subletting or assignment, and shall request in such notification that Landlord consent thereto.

Tenant shall, as Additional Rent, reimburse Landlord promptly for Landlord’s reasonable legal expenses incurred in connection with any request by Tenant for such consent. If Landlord consents thereto, no such subletting or assignment shall in any way impair the continuing primary liability of Tenant hereunder, and no consent to any subletting or assignment in a particular instance shall be deemed to be a waiver of the obligation to obtain the Landlord’s written approval in the case of any other subletting or assignment.

If for any assignment or sublease consented to by Landlord hereunder Tenant receives rent or other consideration, either initially or over the term of the assignment or sublease, in excess of the rent called for hereunder, or in case of sublease of part, in excess of such rent fairly allocable to the part, after appropriate adjustments to assure that all other payments called for hereunder are appropriately taken into account and after deduction for reasonable marketing expenses of Tenant in connection with the assignment or sublease, to pay to Landlord as additional rent fifty (50%) percent of the excess of each such payment of rent or other consideration received by Tenant promptly after its receipt.

7.2 Restoration. If Landlord or Tenant does not elect to so terminate, this Lease shall continue in force and a just proportion of the rent reserved, according to the nature and extent of the damages sustained by the Premises, shall be suspended or abated until the Premises, or what may remain thereof, shall be put by Landlord in proper condition for use, which Landlord covenants to do with reasonable diligence to the extent permitted by the net proceeds of insurance recovered or damages awarded for such taking, destruction or damage and subject to zoning and building laws or ordinances then in existence. “Net proceeds of insurance recovered or damages awarded” refers to the gross amount of such

26

insurance or damages less the reasonable expenses of Landlord incurred in connection with the collection of the same, including without limitation, fees and expenses for legal and appraisal services. If Landlord shall not have restored the Premises within one hundred eighty (180) days from the taking or casualty, Tenant shall have the right to terminate this Lease by giving notice of such termination to Landlord, effective at the expiration of thirty (30) days from the giving of such notice; provided however, that such termination will be rendered ineffective if, prior to the expiration of said 30-day period, Landlord shall have completed such restoration.

7.3 Award. Irrespective of the form in which recovery may be had by law, all rights to damages or compensation shall belong to Landlord in all cases, except for Tenant’s insurance proceeds allocable to personal property and business loss and, in the case of a taking by a public authority, awards made to Tenant for its personal property, fixtures and moving expenses. Except for such awards, Tenant hereby grants to Landlord all of Tenant’s rights to such damages and covenants to deliver such further assignments thereof as Landlord may from time to time request.

7.4 Disbursement of Insurance Proceeds. That parties agree that Tenant’s property insurance on any improvements in the Premises installed by or on behalf of Tenant shall be adjusted and disbursed in accordance with this subsection 7.4. If a fire or other casualty occurs and this Lease is not terminated as a result thereof, the Tenant’s insurance shall be adjusted by Tenant and the proceeds thereof shall be paid to Landlord to fund the Landlord’s restoration work. If the Lease is terminated as a result of a fire or other casualty, then Tenant’s insurance shall be adjusted and the proceeds thereof shall be paid to Tenant, provided, however, that Tenant agrees to pay Landlord for Landlord’s share of the insurance proceeds attributable to the improvements in the Premises installed by or on behalf of Tenant not yet paid for by Tenant at the time of such fire or casualty.

ARTICLE 8

Defaults

8.1 Events of Default. (a) If Tenant shall default in the performance of any of its obligations to pay the Fixed Rent, Additional Rent or any other sum due Landlord hereunder and if such default shall continue for ten (10) days after written notice from Landlord designating such default or if within thirty (30) days after written notice from Landlord to Tenant specifying any other default or defaults Tenant has not commenced diligently to correct the default or defaults so specified or has not thereafter diligently pursued such correction to completion, or (b) if any assignment shall be made by Tenant or any guarantor of Tenant for the benefit of creditors, or (c) if Tenant’s leasehold interest shall be taken on execution, or (d) if a lien or other involuntary encumbrance is filed against Tenant’s leasehold interest or Tenant’s other property, including said leasehold interest, and is not discharged within ten (10) days thereafter, or (e) if a petition is filed by Tenant or any guarantor of Tenant for liquidation, or for reorganization or an arrangement under any provision of any bankruptcy law or code as then in force and effect, or (f) if an involuntary petition under any of the provisions of any bankruptcy law or code is filed against Tenant or any guarantor of Tenant and such involuntary petition is not dismissed

27

within thirty (30) days thereafter, then, and in any of such cases, Landlord and the agents and servants of Landlord lawfully may, in addition to and not in derogation of any remedies for any preceding breach of covenant, immediately or at any time thereafter without demand or notice enter into and upon the Premises or any part thereof in the name of the whole or mail a notice of termination addressed to Tenant, and repossess the same as of landlord’s former estate and expel Tenant and those claiming through or under Tenant and remove its and their effects without being deemed guilty of any manner of trespass and without prejudice to any remedies which might otherwise be used for arrears of rent or prior breach of covenants, and upon such entry or mailing as aforesaid this Lease shall terminate, Tenant hereby waiving all statutory rights to the Premises (including without limitation rights of redemption, if any, to the extent such rights may be lawfully waived) and Landlord, without notice to Tenant, may store Tenant’s effects, and those of any person claiming through or under Tenant, at the expense and risk of Tenant, and, if Landlord so elects, may sell such effects at public auction or private sale and apply the net proceeds to the payment of all sums due to Landlord from Tenant, if any, and pay over the balance, if any, to Tenant. Landlord shall use reasonable efforts to provide Tenant with thirty (30) days prior notice of any such auction or private sale.

8.2 Remedies. In the event that this Lease is terminated under any of the provisions contained in Section 8.1 or shall be otherwise terminated for breach of any obligation of Tenant, Tenant covenants to pay forthwith to Landlord, as compensation, the excess of the total rent reserved for the residue of the term over the rental value of the Premises for said residue of the term. In calculating the rent reserved there shall be included, in addition to the Fixed Rent and Additional Rent, the value of all other considerations agreed to be paid or performed by Tenant for said residue. Tenant further covenants as additional and cumulative obligations after any such termination, to pay punctually to Landlord all the sums and to 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 pursuant to the next preceding sentence Tenant shall be credited with any amount paid to Landlord as compensation as in this Section 8.2 provided and also with the net proceeds of any rent obtained by Landlord by reletting the Premises, after deducting all Landlord’s expense in connection with such reletting, including, without limitation, all 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) 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.

Nothing contained in this Lease shall, however, limit or prejudice the right of Landlord to prove for and obtain in proceedings for bankruptcy or insolvency by reason pf the termination of this Lease, an amount equal to the maximum allowed by any statute or rule

28

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 be greater than, equal to, or less than the amount of the loss or damages referred to above.

8.3 Remedies Cumulative. Any and all rights and remedies which Landlord may have under this Lease, and at law and equity, shall be cumulative and shall not be deemed inconsistent with each other, and any two or more of all such rights and remedies may be exercised at the same time insofar as permitted by law.

8.4 Landlord’s Right to Cure Defaults. Landlord may, but shall not be obligated to, cure, at any time, without notice, any default by Tenant under this Lease; and whenever Landlord so elects, all costs and expenses incurred by Landlord, including reasonable attorneys’ fees, in curing a default shall be paid, as Additional Rent, by Tenant to Landlord on demand, together with lawful interest thereon from the date of payment by Landlord to the date of payment by Tenant.

8.5 Effect of Waivers of Default. Any consent or permission by Landlord to any act or omission which otherwise would be a breach of any covenant or condition herein, shall not in any way be held or construed (unless expressly so declared) to operate so as to impair the continuing obligation of any covenant or condition herein, or otherwise, except as to the specific instance, operate to permit similar acts or omissions.

8.6 No Waiver, etc. The failure of Landlord to seek redress for violation of, or to insist upon the 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 rent with knowledge of the breach of any covenant of this Lease shall not be deemed to have been a waiver of such breach by Landlord. No consent or waiver, express or implied, by Landlord 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.

8.7 No Accord and Satisfaction. No acceptance by Landlord of a lesser sum than the Fixed Rent, Additional Rent or any other charge then due shall be deemed to be other than on account of the earliest installment of such rent or charge due, nor shall any endorsement or statement on any check or any letter accompanying any check or payment as rent or other charge 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.

ARTICLE 9

Rights of Mortgage Holders

9.1 Rights of Mortgage Holders. The word “mortgage” as used herein includes mortgages, deeds of trust or other similar instruments evidencing other voluntary liens or encumbrances, and modifications, consolidations, extensions, renewals, replacements and

29

substitutes thereof. The word “holder” shall mean a mortgagee, and any subsequent holder or holders of a mortgage. Until the holder of a mortgage shall enter and take possession of the Property for the purpose of foreclosure, such holder shall have only such rights of Landlord as are necessary to preserve the integrity of this Lease as security. Upon entry and taking possession of the Property for the purpose of foreclosure, such holder shall have all the rights of Landlord. No such holder of a mortgage shall be liable either as mortgagee or as assignee, to perform, or be liable in damages for failure to perform, any of the obligations of Landlord unless and until such holder shall enter and take possession of the Property for the purpose of foreclosure. Upon entry for the purpose of foreclosure, such holder shall be liable to perform all of the obligations of Landlord, subject to and with the benefit of the provisions of Section 10.4, provided that a discontinuance of any foreclosure proceeding shall be deemed a conveyance under said provisions to the owner of the equity of the Property.

The covenants and agreements contained in this Lease with respect to the rights, powers and benefits of a holder of a mortgage (particularly, without limitation thereby, the covenants and agreements contained in this Section 9.1) constitute a continuing offer to any person, corporation or other entity, which by accepting a mortgage subject to this Lease, assumes the obligations herein set forth with respect to such holder; such holder is hereby constituted a party of this Lease as an obligee hereunder to the same extent as though its name were written hereon as such; and such holder shall be entitled to enforce such provisions in its own name. 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 9.1.

9.2 Lease Superior or Subordinate to Mortgages. It is agreed that the rights and interest of Tenant under this Lease shall be (i) subject or subordinate to any present or future mortgage or mortgages and to any and all advances to be made thereunder, and to the interest of the holder thereof in the Premises or any property of which the Premises are a part if Landlord shall elect by notice to Tenant to subject or subordinate the rights and interest of Tenant under this Lease to such mortgage or (ii) prior to any present or future mortgage or mortgages, if Landlord shall elect, by notice to Tenant, to give the rights and interest of Tenant under this Lease priority to such mortgage; in the event of either of such elections and upon notification by Landlord to that effect, the rights and interest of Tenant under this Lease should be deemed to be subordinate to, or have priority over, as the case may be, said mortgage or mortgages, irrespective of the time of execution or time of recording of any such mortgage or mortgages (provided that, in the case of subordination of this Lease to any future mortgages, the holder thereof agrees not to disturb the possession of Tenant so long as Tenant is not in default hereunder and Tenant and the holder execute a commercially reasonable subordination, non-disturbance and attornment agreement in the holder’s usual and customary form). Tenant agrees it will, upon not less than ten (10) days’ prior written request by Landlord, execute, acknowledge and deliver any and all commercially reasonable instruments deemed by Landlord necessary or desirable to give effect to or notice of such subordination or priority. Any Mortgage to which this Lease shall be subordinated may contain such terms, provisions and conditions as the holder deems usual or customary. Landlord shall use reasonable

30

efforts to obtain a so-called non-disturbance agreement for the benefit of Tenant from its current lender in said lender’s usual and customary form.

ARTICLE 10

Miscellaneous Provisions

10.1 Notices from One Party to the Other. All notices required or permitted hereunder shall be in writing and addressed, if to the Tenant, at the Original Notice Address of Tenant or such other address as Tenant shall have last designated by notice in writing to Landlord and, if to Landlord, at the Original Notice Address of Landlord or such other address as Landlord shall have last designated by notice in writing to Tenant. Any notice shall be deemed duly given when mailed to such address postage prepaid, by registered or certified mail, return receipt requested, or when delivered to such address by hand.

10.2 Quiet Enjoyment. Landlord agrees that upon Tenant’s paying the rent and performing and observing the agreements, conditions and other provisions on its part to be performed and observed, Tenant shall and may peaceably and quietly have, hold and enjoy the Premises during the term hereof without any manner of hindrance or molestation from Landlord or anyone claiming under Landlord, subject, however, to the terms of this Lease.

10.3 Lease not to be Recorded. Tenant agrees that it will not record this Lease. Both parties shall, upon the request of either, execute and deliver a notice or short form of this Lease in such form, if any, as may be permitted by applicable statute.

10.4 Limitation of Landlord’s Liability. The term “Landlord” as used in this Lease, so far as covenants or obligations to be performed by Landlord are concerned, shall be limited to mean and include only the owner or owners at the time in question of the Property, and in the event of any transfer or transfers of title to said property, the Landlord (and in case of any subsequent transfers or conveyances, the then grantor) shall be concurrently freed and relieved from and after the date of such transfer or conveyance, without any further instrument or agreement of all liability as respects the performance of any covenants or obligations on the part of the Landlord contained in this Lease thereafter to be performed, it being intended hereby that the covenants and obligations contained in this Lease on the part of Landlord, shall, subject as aforesaid, be binding on the Landlord, its successors and assigns, only during and in respect of their respective successive periods of ownership of said leasehold interest or fee, as the case may be. Tenant, its successors and assigns, shall not assert nor seek to enforce any claim for breach of this Lease against any of Landlord’s assets other than Landlord’s interest in the Property and in the rents, issues and profits thereof, and Tenant agrees to look solely to such interest for the satisfaction of any liability or claim against Landlord under this Lease, it being specifically agreed that in no event whatsoever shall Landlord (which term shall include, without limitation, any general or limited partner, trustees, beneficiaries, officers, directors, or stockholders of Landlord) ever be personally liable for any such liability.

31

10.5 Acts of God. In any case where either party hereto is required to do any act, delays caused by or resulting from Acts of God, war, civil commotion, fire, flood or other casualty, labor difficulties, shortages of labor, materials or equipment, government regulations, unusually severe weather, or other causes beyond such party’s reasonable control shall not be counted in determining the time during which work shall be completed, whether such time be designated by a fixed date, a fixed time or a “reasonable time,” and such time shall be deemed to be extended by the period of such delay.

10.6 Landlord’s Default. Landlord shall not be deemed to be in default in the performance of any of its obligations hereunder unless it shall fail to perform such obligations and such failure shall continue for a period of thirty (30) days or such additional time as is reasonably required to correct any such default after written notice has been given by Tenant to Landlord specifying the nature of Landlord’s alleged default. Landlord shall not be liable in any event for incidental or consequential damages to Tenant by reason of Landlord’s default, whether or not notice is given. Tenant shall have no right to terminate this Lease for any default by Landlord hereunder and no right, for any such default, to offset or counterclaim against any rent due hereunder.

10.7 Brokerage. Tenant warrants and represents that it has dealt with no broker in connection with the consummation of this Lease, other than Nordblom Company and GVA Thompson Doyle Hennessey & Stevens (the “Brokers”), and in the event of any brokerage claims, other than by the Brokers, against Landlord predicated upon prior dealings with Tenant, Tenant agrees to defend the same and indemnify and hold Landlord harmless against any such claim. Landlord warrants and represents that it has dealt with no broker in connection with the consummation of this Lease, other than the Brokers, and in the event of any brokerage claims, other than by the Brokers, against Tenant predicated upon prior dealings with Landlord, Landlord agrees to defend the same and indemnify and hold Tenant harmless against any such claim.

10.8 Applicable Law and Construction. This Lease shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts and, if any provisions of this Lease shall to any extent be invalid, the remainder of this Lease shall not be affected thereby. There are no oral or written agreements between Landlord and Tenant affecting this Lease. This Lease may be amended, and the provisions hereof may be waived or modified, only by instruments in writing executed by Landlord and Tenant. The titles of the several Articles and Sections contained herein are for convenience only and shall not be considered in construing this Lease. Unless repugnant to the context, the words “Landlord” and “Tenant” appearing in this Lease shall be construed to mean those named above and their respective heirs, executors, administrators, successors and assigns, and those claiming through or under them respectively. If there be more than one tenant, the obligations imposed by this Lease upon Tenant shall be joint and several.

32

ARTICLE 11

Hazardous Materials

11.1 No Releases of Hazardous Materials. Tenant covenants and agrees not to use, release, dispose, manufacture, store, or transport any Hazardous Materials (hereinafter defined) at, on, under or from the Premises and the Property except in compliance with any and all laws, regulations, ordinances or orders promulgated, and as may be amended, by any governmental authority having jurisdiction over the Hazardous Materials or the Property (collectively, “Legal Requirements”), and except for those Hazardous Materials used in the ordinary course of Tenant’s business, but only in compliance with all applicable Legal Requirements and any reasonable requirements of Landlord (such as requirements for fencing or other locked enclosures). Tenant shall comply with all governmental reporting requirements with respect to Hazardous Materials and all chemicals and flammable substances (in whatever form) used by Tenant in its business operations, and shall deliver to Landlord copies of all such reports. In the event that a release or threat of release of Hazardous Materials occurs at, from or upon the Premises or Property during the term of this Lease, Tenant shall at its expense perform all actions required under any and all applicable Legal Requirements to assess, contain, remove or respond to such release or threat of release; provided, however, that Tenant’s work or actions hereunder shall be subject to Landlord’s prior approval, which approval shall not be unreasonably withheld. Notwithstanding the foregoing sentence, in the event of an environmental emergency whereby a governmental authority having jurisdiction has directed or Legal Requirements specify Tenant to take immediate action to report and/or to contain, remove or respond to a release or threat of release, and provided Tenant has used reasonable efforts to contact Landlord for approval as aforesaid and Landlord has failed to timely respond to Tenant, Tenant shall be permitted to take such immediate action and shall use best efforts to inform Landlord of the actions so taken, it being understood and agreed that any further actions beyond the emergency action shall still require Landlord’s approval as aforesaid. The term “Hazardous Materials” shall mean any and all materials defined or classified as “hazardous materials” “hazardous waste,” “hazardous substance,” “toxic substance,” “hazardous pollutant,” “toxic pollutant” or “oil” under 42 U.S.C. §9601 et. seq. (CERCLA), 42 U.S.C. §6901 et. seq. (RCRA), M.G.L. c. 21C or M.G.L. c. 21E and any regulations promulgated pursuant to those statutes, all as amended.

11.2 Notices of Release of Hazardous Materials. Tenant shall promptly notify Landlord in writing of all spills, releases or threat of release of Hazardous Materials caused by or involving Tenant or its business operations, and all notices, orders, fines or communications of any kind received by Tenant from any governmental authority or third party concerning the presence or suspected presence of Hazardous Materials on the Premises or the Property, the migration or suspected migration of Hazardous Materials from the Premises or the Property to other property, or the migration or suspected migration of Hazardous Materials from other property to the Premises or the Property.

11.3 Landlord’s Right to Inspect. Landlord, its officers, employees, contractors and agents shall have the right, but not the duty, to inspect areas of the Premises, Building and Property to determine whether Tenant is complying with CERCLA, RCRA, Chapter 21C,

33

Chapter 21E, and other state and federal environmental laws, or regulations promulgated pursuant to any of the foregoing, as amended. Landlord shall use reasonable efforts to minimize interference with Tenant’s business, but shall not be liable for any interference caused thereby, provided Landlord shall have used such reasonable efforts. Landlord shall use reasonable efforts to perform such inspections pursuant to this Section 11.3 during normal business hours.

11.4 Landlord’s Right to Audit. Tenant shall permit Landlord, its employees and its agents (including its environmental consultant), access to all areas of the Premises for the purposes of conducting an environmental assessment or inspection during regular business hours, or during other hours either by agreement of the parties or in the event of an environmental emergency. In the event Landlord shall exercise its rights under this Section 11.4, (i) Landlord shall use reasonable efforts to minimize interference with Tenant’s business, but shall not be liable for any interference caused thereby, provided Landlord shall have used such reasonable efforts; and (ii) except in the case of an environmental emergency, Landlord shall exercise said assessment or inspection right no more than one time during any 12 month period of the term, provided, however, that said limitation of one audit every 12 months (a) shall not apply and be counted towards any assessments or inspections required by any lender of Landlord; and (b) shall be deemed void and of no force and effect in the event Landlord has a reasonable belief that a release or threat of release of Hazardous Materials or a violation of a Legal Requirement existed or exists at, on, under or from the Premises or the Property.

11.5 Tenant Audit. Landlord shall have the right, from time to time, during the term of this Lease (provided that Landlord has a reasonable belief that Hazardous Materials are present on the Property and are in violation of any Legal Requirements and has delivered to Tenant evidence to support such belief) and upon the expiration of the term of this Lease, to require that Tenant hire, and in such event, Tenant shall at its own expense hire, an environmental consultant satisfactory to Landlord to undertake an environmental assessment, inspection and/or sampling at the Property to determine whether Hazardous Materials have been released during the term of the Lease.

11.6 Remediation. Should the assessment, inspection or sampling performed pursuant to Sections 11.4 or 11.5 above, or any other assessment, inspection or sampling, reveal that there has been a release or threat of release of Hazardous Materials by Tenant or its employees, agents or contractors, then Tenant shall, at its expense, undertake all response actions required by Landlord or any Legal Requirement, and Tenant shall promptly thereafter restore any areas damaged or affected by such response actions.

11.7 Tenant’s Reporting Requirements; Management and Safety Plan. Upon the execution of this Lease, Tenant shall submit to Landlord a list that specifies the materials that Tenant will use or store on the Premises in the ordinary course of its business. Tenant shall provide Landlord with an updated list every twelve (12) months. Any additions to said list will be subject to the approval of Landlord, which shall not be unreasonably withheld or delayed, provided, however, that Landlord’s approval shall not be required if said materials are being used solely and exclusively by Tenant and in connection with the research and development and manufacturing of medical devices. In all other cases,

34

Landlord’s approval shall be required. Within thirty (30) days after the Date of this Lease, Tenant shall at its expense prepare and deliver to Landlord and Landlord’s environmental consultant for their review and approval a so-called “Chemical Management and Facility Safety Plan” (the “Plan”). Tenant shall amend the Plan if requested by Landlord. Tenant shall operate its business at the Premises in accordance with the procedures and practices set forth in said Plan, and shall promptly remedy from time to time any practices, procedures or conditions, at Tenant’s expense, that violate, or which in the reasonable judgment of Landlord or its consultant, would with the passage of time violate, the provisions of this Article 11.

11.8 Indemnification. Tenant agrees to indemnify and save Landlord harmless from all claims, liability, loss or damage arising on account of the use, release, threat of release, holding, handling, transport, storage, or disposal of Hazardous Materials by Tenant, its employees, agents or contractors at, on, upon or from the Premises or Property from and after the Date of this Lease, including, without limitation, liability under any federal, state, or local laws, requirements and regulations, or damage to any of the systems of the Building or the Property. The provisions of this Section 11.8 shall survive the expiration or earlier termination of this Lease.

11.9 Notice to Tenant. Landlord shall use reasonable efforts to notify Tenant of any release of Hazardous Materials by any other tenants of the Park on any properties owned by Landlord which abut the Property provided Landlord first has knowledge of the same.

11.10   Delivery of Reports. Tenant acknowledges and agrees that Landlord has furnished to Tenant (a) a letter dated March 11, 2003 from GEI Consultants, Inc. to Nordblom Management Company regarding “Property Status Update: Building 5, 63 Second Avenue, Northwest Park, Burlington, Massachusetts”; (b) a Preliminary Environmental Site Assessment Update dated July 30, 1997 regarding Building 5, 63 Second Avenue, Northwest Park, Burlington, Massachusetts; and (c) an asbestos report to be prepared by Smith & Wessel Associates, Inc. (the “Asbestos Report”) (collectively, (a) - (c) are hereinafter referred to as the “Environmental Reports”). Landlord represents to Tenant that Landlord has no knowledge of any release or threat of release of Hazardous Materials on the Premises other than what is described and set forth in the Environmental Reports.

11.11   Asbestos. Landlord shall be responsible at its sole cost and expense for removing or encapsulating asbestos, if any, found in the Building, if such removal or encapsulation is recommended by the Asbestos Report (the “Asbestos Work”). In the event Tenant is actually delayed in completing Tenant’s Work and occupying the Premises by June 1, 2003 solely as a result of Landlord performing the Asbestos Work, the Rent Commencement Date shall be postponed by one (1) day for each day of delay directly caused by Landlord’s performance of the Asbestos Work.
