ARTICLE 2

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, stairwells, elevators and elevator shafts, 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, 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, stairways, loading docks and elevators of the Building, (b) common walkways and driveways necessary for access to the Building, (c) the common parking areas serving the Building, and (d) 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 be permitted to use twenty-five (25) parking spaces in the parking area serving the Building.

Landlord reserves the right from time to time, 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 (provided the same, to the extent within the Premises, shall be located, to the extent reasonably practicable, in the central core area of the Building, within the ceiling plenum, behind the walls or below the floors, or within the chases, risers, ducts, conduits, lines, shafts or similar concealed areas), (b) to alter or relocate any other common facility and/or common areas of the Building, (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. Except in the case of emergency, Landlord shall provide Tenant with reasonable prior notice (which notice may be given verbally) of any such access to the Premises for any of the foregoing.

Notwithstanding anything to the contrary contained in this Lease, Tenant acknowledges that Landlord is planning on altering portions of the common areas of the Building (such alterations the “Common Area Work”), and that as part of the Common Area Work the demising walls of the Premises may need to be relocated (it being agreed any such relocation of demising walls will occur prior to the Commencement Date). Tenant acknowledges that, to perform certain portions of the Common Area Work, Landlord may need access to, and perform work within, the Premises. Tenant agrees that Landlord shall be permitted to enter the Premises and perform the Common Area Work during normal business hours, and Tenant shall cooperate with Landlord’s reasonable requirements to facilitate such Common Area Work. Landlord shall use reasonable efforts while conducting such activities to minimize any interference with Tenant’s use of the Premises. To the extent that the demising walls of the Premises were relocated as part of the Common Area Work then, within sixty (60) days of completion of the Common Area Work, Landlord shall verify the new measurement of the Premises, and the pertinent economic terms (including parking rights) set forth under this Lease affected by the size of the Premises shall be adjusted to account for such new measurement (it being agreed that in no event shall the measurement of the Premises vary by more than five hundred (500) rentable square feet from what is listed in Section 1.1). Landlord and Tenant agree to enter into a letter agreement or amendment to this Lease memorializing such adjustments, if applicable, but failure of the parties to execute such a document shall have no effect on the effectiveness of the adjustment of the Premises pursuant to this paragraph and the economic terms associated therewith.

4

2.2 Term. TO HAVE AND TO HOLD for an original term (the “Original Term”) beginning on the Commencement Date, which shall be the earlier of (a) the date on which the work to be performed by Landlord pursuant to Exhibit C (“Landlord’s Work”) has been substantially completed or (b) the opening by Tenant of its business in the Premises (as distinct from working in the Premises to install its furniture, fixtures, wiring and equipment), and ending on the Expiration Date, unless sooner terminated as hereinafter provided. The term “substantially completed” as used herein shall mean that the work to be performed by Landlord pursuant to Exhibit C has been completed with the exception of minor items which can be fully completed without material interference with Tenant and other items which because of the season or weather or the nature of the item are not practicable to do at the time, provided that none of said items is necessary to make the Premises tenantable for the Permitted Uses. However, if Landlord is delayed from Substantially Completing Landlord’s Work on or before the Target Delivery Date because of a Tenant Delay (defined below), then Landlord’s Work shall be deemed to be “Substantially Completed” on the date that such work would have been Substantially Completed but for such Tenant Delay (but Landlord shall not be relieved of the obligation to actually complete Landlord’s Work).

The phrase, “Tenant Delay”, shall be defined as any delay in the completion of Landlord’s Work caused by (i) special work, upgrades or long lead-time items for which Landlord identifies a specified period of delay (it being agreed that Tenant shall not select any item that Landlord identifies as long lead-time items), and in either instance Tenant does not withdraw or alter such special work, upgrade, long lead-time item which avoids such delay, (ii) any changes to any plans made by Tenant, or any Work Change Order requested by Tenant, in any case for which Landlord identifies a specified period of delay at the time of its approval and for which Tenant does not withdraw such change to avoid delay, (iii) the delay of Tenant or its architects and engineers in providing or approving any plans, specifications, pricing or estimates or giving authorizations or supplying information reasonably required by Landlord or its general contractor within three (3) business days after request therefor, (v) any failure by any contractors employed by Tenant including, without limitation, contractors furnishing telecommunications, data processing or other service or equipment directly to Tenant (and not via Landlord’s contractors) to comply with the agreed upon timetables for coordination of the parties’ respective components of work, as established aton-site progress meetings between Landlord’s representative and Tenant’s representative, (vi) any failure by Tenant to comply with the terms of the Lease, including but not limited to Article 3, or any material interference with the performance of Landlord’s Work by Tenant or any of its agents, employees, architects, engineers or contractors (including but not limited to delays caused by the acts or omissions of Tenant or such parties), (vii) Tenant’s delay in delivering the initial Cash Deposit and/or Original Letter of Credit required pursuant to Section 4.4 or (viii) Tenant’s failure to sign and deliver this Lease to Landlord on before October 5, 2016.

When the dates of the Commencement Date and Rent Commencement Date 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) 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. The term “Partial Lease Year” shall mean the time period comprised of the first two (2) full calendar months of the seventh (7th) Lease Year.. The Partial Lease Year shall begin on the first day following the end of the sixth (6th) Lease Year.

2.3 Extension Option. A. Tenant shall have the option (the “Extension Option”) to extend the Term of this Lease for one additional period of five (5) 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 Extension Notice (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;

5

(ii) Tenant shall have had a net income for the12-month period immediately preceding the date of the Extension Notice and for the12-month period immediately preceding the commencement of the Extended Term; and

(iii) Simultaneously with the delivery of the Extension Notice and also at the commencement of the Extended Term, Tenant shall have delivered to Landlord an audited statement (or, if such audited statement is not available, then an unaudited statement signed and certified by Tenant’s Chief Financial Officer), prepared by Tenant’s accountant using generally accepted accounting principles, evidencing such net income during each of the periods specified in clause (ii) hereinabove.

B. All of the terms, covenants and provisions of this Lease shall apply to the Extended Term except that the Annual Fixed Rent Rate for such extension period shall be the market rate at the commencement of the Extended Term (“Market Rate”), as designated by Landlord (subject to Tenant’s right to dispute the same and the dispute resolution mechanism set forth below). If Tenant shall elect to exercise this Extension Option, it shall do so by giving Landlord written notice (the “Extension Notice”) of its intention to do so no earlier than twelve (12) months and no later than nine (9) months prior to the expiration of the Original Term of this Lease, time being of the essence thereof. If timely and properly Tenant gives such notice and satisfies the conditions specified above, the extension of this Lease shall be automatically effected without the execution of any additional documents. The Original Term and the Extended Term are hereinafter collectively called the “Term” or the “term”.

C. Not later than thirty (30) days following the giving of Tenant’s Extension Notice, Landlord shall notify Tenant of Landlord’s determination of the Market Rate for the Extended Term. Within fifteen (15) days after Landlord gives Tenant Landlord’s determination of the Market Rate, Tenant shall notify Landlord whether Tenant accepts or disputes such rate. If Tenant disagrees with Landlord’s determination, then Landlord and Tenant shall commence negotiations to agree upon the Market Rate. 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 the Extended Term. If Landlord and Tenant are unable to reach agreement on the Market Rate within thirty (30) days after the date on which Landlord first gave Tenant Landlord’s proposal for the Market Rate, then the Market Rate shall be determined as provided below.

D. If Landlord and Tenant are unable to agree on the Market Rate by the end of said thirty(30)-day period, then within ten (10) days thereafter, Landlord and Tenant shall each simultaneously submit to the other in a sealed envelope its good faith estimate of the Market Rate. If the higher of such estimates is not more than one hundred five percent (105%) of the other estimate, then the Market Rate shall be the average of the two estimates. If the matter is not resolved by the exchange of estimates, then Market Rate shall be determined by an independent arbitrator as set forth below.

E. Within seven (7) days after the exchange of estimates, the parties shall select, as an arbitrator, a mutually acceptable commercial real estate broker or appraiser licensed in the Commonwealth of Massachusetts specializing in the field of commercial office leasing in the Burlington area, having no less than ten (10) years’ experience (an “Approved Arbitrator”). If the parties cannot agree on such person, then within a second period of seven (7) business days, each shall select one Approved Arbitrator and the two appointed Arbitrators shall, within five (5) business days, select a third Approved Arbitrator who shall be the final decision-maker (the “Final Arbitrator”). If one party shall fail to timely make such appointment, then the person chosen by the other party shall be the sole arbitrator. Once the Final Arbitrator has been selected as provided for above, then, as soon thereafter as practicable, but in any case within fourteen (14) days after his or her appointment, the arbitrator shall determine the Market Rate by selecting either the Landlord’s estimate of Market Rate or the Tenant’s estimate of Market Rate. Such arbitrator must choose the

6

proposed Market Rate that he/she determines is closest to the actual market rental rate for the Premises. There shall be no discovery or similar proceedings. The arbitrator’s decision as to which estimate shall be the Market Rate for the Extended Term shall be rendered in writing to both Landlord and Tenant and shall be final and binding upon them and shall be the Annual Fixed Rent for the Extended Term. The costs of the Final Arbitrator will be equally divided between Landlord and Tenant. Any fees of any Approved Arbitrator or counsel engaged by Landlord or Tenant, however, shall be borne by the party that retained such Approved Arbitrator or counsel. If the dispute between the parties as to a market rate has not been resolved before the commencement of the Extended Term, then Tenant shall pay Fixed Rent under the Lease based upon the market rate designated by Landlord until either the agreement of the parties as to the market rate, or the decision of the Final Arbitrator, as the case may be, at which time Tenant shall pay any underpayment of Fixed Rent to Landlord, or Landlord shall refund any overpayment of Fixed Rent to Tenant.

F. Once the Market Rate has been determined, the parties shall promptly execute an amendment to this Lease setting forth the Fixed Rent for the Premises during the Extended Term.

G. Tenant’s rights to extend pursuant to this Section 2.3 are personal to the initial named Tenant, Avedro, Inc., and, except to a Permitted Transferee (as defined in Section 6.2.1), may not be assigned under any circumstances.

H. With respect to any assignment or subletting during the Original Term of this Lease, such assignment shall not include the right granted to Tenant under this Section 2.3 hereinabove to extend the Term, and such sublease shall be for a term expiring no later than the Expiration Date.

ARTICLE 3

Improvements

3.1 Performance of Work and Approval of Landlord’s Work. Landlord shall cause to be performed the work required by Exhibit C, the Work Letter, and consistent with the space plan attached hereto as ExhibitC-1. All such work shall be done in a good and workmanlike manner employing Building-standard materials and finishes and so as to conform to all applicable building laws and codes (as such laws and codes, including but not limited to all Federal and State laws and codes, are enforced by the Town of Burlington, Massachusetts). Tenant agrees that Landlord may make any changes in such work which may become reasonably necessary or advisable, other than substantial changes, without approval of Tenant, provided written notice is promptly given to Tenant, and provided such changes do not result in a quality or finish below Building-standard materials and finishes. Provided the Lease is fully executed on or before October 5, 2016, then Landlord shall use diligence to cause Landlord’s work to be substantially completed by the Target Delivery Date, subject to the provisions of Section 10.5 hereof and any Tenant Delay. Landlord agrees that Tenant may make changes in such work with the approval of Landlord and the execution by Landlord and Tenant of a Work Change Order, in the form attached hereto as Exhibit D.

If, for any reason other than a Tenant Delay or a delay attributable to Force Majeure, Landlord’s Work has not been Substantially Completed on or before February 1, 2017 (the “Outside Delivery Date”), then Tenant shall accrue one (1) day of free Fixed Rent for each day of delay after the Outside Delivery Date until the date Landlord has done so. Further, if, for any reason other than a Tenant Delay or a delay attributable to Force Majeure, Landlord’s Work has not been Substantially Completed on or before April 1, 2017, then Tenant shall have the right to terminate this Lease by giving written notice of such termination to Landlord, with such written notice to be given by Tenant no later than April 6, 2017 and such termination to be 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 said30-day period, Landlord shall have Substantially Completed Landlord’s Work. The foregoing shall be Tenant’s sole remedies at law or in equity for Landlord’s failure to Substantially Complete Landlord’s Work.

7

3.2 Acceptance of the Premises. Tenant or its representatives may, at reasonable times, enter upon the Premises during the progress of the work to inspect the progress thereof and to determine if the work is being performed in accordance with the requirements of Section 3.1. Tenant shall promptly give to Landlord notices of any alleged failure by Landlord to comply with those requirements. Landlord’s Work shall be deemed approved by Tenant when Tenant occupies the Premises for the conduct of its business, except for items of Landlord’s Work which are uncompleted or do not conform to Exhibit C and as to which Tenant shall, in either case, have given written notice to Landlord prior to, or within five (5) days following, such occupancy. A certificate of completion by a licensed architect or registered engineer shall be conclusive evidence that Landlord’s Work has been completed except for items stated in such certificate to be incomplete or not in conformity with Exhibit C.

3.3 Early Access. Upon full execution of the Lease, Tenant may, prior to the Commencement Date (but following coordination with Landlord as to the timing), enter the Premises and without payment of rent, but otherwise subject to all the terms and conditions of this Lease, for the purpose of installing Tenant’s furniture, fixtures, wiring and equipment, provided that (i) Tenant shall not interfere with any work then being performed by or for Landlord in the Premises or Building, (ii) Tenant shall immediately cease its activities in the Premises in the event that Landlord notifies Tenant (which notice may be given orally) that Tenant is interfering with Landlord, and (iii) provided Tenant shall reimburse Landlord for Landlord’s actual costs incurred in connection with Tenant’spre-commencement entry. All such work shall be done in accordance with, and Tenant shall comply with, the provisions of Section 6.2.5 hereof.

ARTICLE 4

Rent

4.1 The Fixed Rent. (a) Commencing on the Rent Commencement Date, Tenant covenants and agrees to pay rent to Landlord, by electronic fund transfer (or by such other method, as set forth below, 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, without notice or demand, and without setoff, abatement, suspension, deferment, reduction or deduction, except as otherwise expressly provided herein, on the first day of each calendar month included in the term; and for any portion of a calendar month at beginning of the term, at the rate for the first lease year payable in advance for such portion. The term “Additional Rent” shall mean all sums other than Fixed Rent that are payable to Landlord under this Lease, including, without limitation all Operating Costs, Taxes, late charges, and interest.

(b) It is the intention of the parties hereto that the obligations of Tenant hereunder shall be separate and independent covenants and agreements, that the Annual Fixed Rent, the Additional Rent and all other sums payable by Tenant to Landlord shall continue to be payable in all events and that the obligations of Tenant hereunder shall continue unaffected, unless the requirement to pay or perform the same shall have been abated or terminated pursuant to an express provision of this Lease.

(c) If Landlord shall give notice to Tenant that all rent and/or other payments due hereunder are to be made to Landlord by check, or by any other commercially reasonable means, Tenant shall make all such payments as shall be due after receipt of said notice by means as designated by Landlord, with such payments to be made to such address and to such person or entity as is specified by Landlord.

4.2 Additional Rent. Commencing on the Commencement Date, 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 covenants to 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

8

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 twenty (20) days following a written notice to Tenant, which notice shall set forth the manner of computation of Tenant’s Percentage of Taxes). This section shall survive the expiration or earlier termination of the Lease.

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.

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, estate, inheritance, succession, capital levy, transfer, income or excess profits taxes assessed on Landlord. 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. Any special assessments from any governmental authority which are not specifically charged to Tenant and which can be paid by Landlord in installments over a period in excess of one year, shall be paid by Landlord in the maximum number of installments permitted by law and not included as Taxes except in the year in which the installment is actually paid.

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 covenants to 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. This section shall survive the expiration or earlier termination of the Lease.

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) cleaning, maintenance and upkeep of the Premises, and (ii) the provision of electricity to the Premises;

10

(j) any cost representing an amount paid to a person, firm, corporation or other entity related to Landlord that is in excess of the amount which would have been paid in the absence of such relationship;

(k) late fees or charges incurred by Landlord due to late payment of expenses, except to the extent attributable to Tenant’s actions or inactions;

(o) costs incurred in connection with bringing the Building into compliance with any laws and/or codes in effect and enforced prior to the Commencement Date; and

(p) capital expenditures, except as specifically provided for below.

If, during the term of this Lease, Landlord shall replace any capital items or make any capital expenditures which (a) are intended to reduce Operating Costs or (b) are required to comply with laws enacted after the date of this Lease, or (c) following the expiration of the first (1^st) Lease Year, are required to replaceworn-out items as may be necessary to maintain the Building in good working order, repair and condition and not to enhance the Building over and above its current appearance and condition (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 annualcharge-off of such capital expenditure. (Annualcharge-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

11

that a particular capital expenditure will effect savings in Operating Costs and that such annual projected savings will exceed the annualcharge-off of capital expenditure computed as aforesaid, then and in such events, the annualcharge-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, amenities or benefits being supplied hereunder, actual Operating Costs incurred that vary due to occupancy 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. Notwithstanding the foregoing, Landlord shall not recover in any given year more that 100% of the Operating Costs actually incurred by Landlord in such year.

4.2.4 Insurance. Tenant shall, at its expense, as Additional Rent, take out and maintain from the time Tenant first occupies the Premises for any purpose and throughout the Term the following insurance protecting Landlord:

4.2.4.1 Commercial general liability insurance and commercial excess liability insurance on “follow form” basis and/or umbrella naming Landlord, Tenant, and Landlord’s managing agent and any mortgagee of which Tenant has been given notice as insureds or additional insureds on a primary andnon-contributory basis, 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 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, coverning the state in which the employee was hired, works and resides; and Employers liability insurance with minimum limits of Five Hundred Thousand Dollars ($500,000.00) each accident, bodily injury by accident; Five Hundred Thousand Dollars ($500,000.00) each employee, bodily injury by disease; and Five Hundred Thousand Dollars ($500,000.00) policy limit, bodily injury by disease.

4.2.4.2 Special Risk property insurance with the usual extended coverage endorsements covering all Tenant’s furniture, furnishings, fixtures and equipment, and business interruption insurance with limits not less than the equivalent of 12 months of rent, with extra expense coverage, and shall list Landlord as loss payee as their interests may appear.

4.2.4.3 Automobile liability insurance for all owned, leased,non-owned and hired vehicles. The minimum limit of liability shall be One Million Dollars ($1,000,000.00) each accident, combined single limit for bodily injury and property damage, naming Landlord as an additional insured on a primary andnon-contributory basis.

4.2.4.4 All such policies shall be obtained from responsible companies having a policy rating ofA-; X or better, as set forth in the most current issue of the Best’s Key Rating Guide and which are qualified to do business and in good standing in Massachusetts. 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. Tenant shall provide at least thirty (30) days prior written notice to Landlord should any of the policies required herein be cancelled. 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.

12

4.2.4.5 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, workmen’s compensation insurance, and all liability insurance, 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. 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.

4.2.5 Utilities. Commencing as of the Commencement Date, Tenant shall contract for and pay directly to the applicable public utility company all costs and charges for telephone service and for separately metered electricity and gas furnished or consumed on the Premises (Landlord hereby confirming such meters currently exist and are in good working order). Tenant shall reimburse Landlord through Operating Costs for all charges for water (including sewer charges) supplied by Landlord pursuant to Subsections 5.1.3. Tenant shall pay directly all charges for other utilities or services not supplied by Landlord, 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 Fixed Rent or other sum due Landlord 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. In addition, if any installment of rent or other sum due Landlord is not paid when due, such installment shall bear interest from the date due until paid, at the rate of 12% per year not to exceed the highest rate permitted by law.

4.4 Letter of Credit. The performance of Tenant’s obligations under this Lease shall be secured by a letter of credit throughout the term hereof in accordance with and subject to the following terms and conditions:

4.4.1 Amount of Security. (a) Concurrently with Tenant’s execution and delivery of this Lease, Tenant shall deposit with Landlord cash in the amount of the Letter of Credit Amount set forth in Section 1.1 (the “Cash Deposit”). The Cash Deposit paid by Tenant to Landlord shall be held by Landlord and be withdrawn and applied by Landlord under the same circumstances and for the same purposes as if it were a Letter of Credit (in accordance with the terms of Section 4.4). Upon any such application of all or part of the Cash Deposit by Landlord, Tenant shall, within five (5) days of written demand therefor, deliver to Landlord cash in the amount of the Cash Deposit so applied.

(b) Within fifteen (15) days of the Date of this Lease, Tenant shall deliver to Landlord an irrevocable standby letter of credit (the “Original Letter of Credit”) which shall be (i) in the form of Exhibit E attached to this Lease (the “Form LC”), (ii) issued by a commercial bank reasonably satisfactory to Landlord upon which

13

presentment may be made in Boston, Massachusetts, (iii) in the amount equal to the Letter of Credit Amount, and (iv) for a term of at least 1 year, subject to the provisions of Section 4.4.2 below. Within five (5) days of Tenant’s delivery of the Original Letter of Credit to Landlord, Landlord shall return the Cash Deposit (or so much of the same as remains following any withdrawal against the same pursuant to the terms above) to Tenant. The Original Letter of Credit, any Additional Letters(s) of Credit and Substitute Letter(s) of Credit are referred to herein as the “Letter of Credit.” Time is of the essence with regard to the delivery of the Original Letter of Credit.

(b) The Letter of Credit Amount may be reduced one (1) time during the Term (as set forth below) provided Tenant is not in default under this Lease at the time of the reduction, and has not previously been in default under this Lease. Provided Tenant satisfies the above conditions, the Letter of Credit Amount shall be reduced following the expiration of the thirty-eighth (38^th) full calendar month following the Commencement Date (such date the “Reduction Date”) to an amount equal to $25,326.00 pursuant to the following procedures. Tenant shall provide Landlord with written notice of Tenant’s intent to reduce the Letter of Credit Amount pursuant to the terms hereof on or following the Reduction Date. Within thirty (30) days after Tenant receives written confirmation from Landlord that the conditions for reduction of the Letter of Credit Amount have been satisfied, Tenant shall provide Landlord with an amendment to the Letter of Credit or a Substitute Letter of Credit meeting all of the requirements of this Section 4.4 to accomplish such authorized reduction of the Letter of Credit, and Landlord will have no obligation to surrender the Letter of Credit unless and until receipt of the Substitute Letter of Credit or amended Letter of Credit in compliance with such requirements. In no event shall the Letter of Credit have an automatic reduction provision. In no event will the Letter of Credit at any time be reduced below $25,326.00. Tenant shall be responsible, at its sole expense, for taking all necessary steps to effect the reduction pursuant to the terms hereof, provided however that Landlord shall reasonably cooperate with Tenant to amend the Letter of Credit or obtain a Substitute Letter of Credit, as applicable, at no cost to Landlord.

4.4.2 Renewal of Letter of Credit. Each Letter of Credit shall be automatically renewable in accordance with the second to last paragraph of the Form LC; provided however, that Tenant shall be required to deliver to Landlord a new letter of credit (a “Substitute Letter of Credit”) satisfying the requirements for the Original Letter of Credit under Section 4.4.1 on or before the date 30 days prior to the expiration of the term of the Letter of Credit then in effect, if the issuer of such Letter of Credit (the “Issuing Bank”) gives notice of its election not to renew such Letter of Credit for any additional period pursuant thereto. Should any Letter of Credit contain a final expiration date, in addition to a current expiration date, such final expiration date shall be no earlier than 45 days following the Expiration Date of this Lease.

4.4.3 Draws to Cure Defaults. If the Fixed Rent, Additional Rent or any other sum payable to Landlord 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 in all cases beyond the expiration of all applicable notice and cure periods, then Landlord shall have the right, at any time thereafter to draw down from the Letter of Credit the amount necessary to cure such default. In the event of any such draw by the Landlord, Tenant shall, within 30 days of written demand therefor, deliver to Landlord an additional Letter of Credit (“Additional Letter of Credit”) satisfying the requirements for the Original Letter of Credit, except that the amount of such Additional Letter of Credit shall be the amount of such draw.

4.4.4 Draws to Pay Damages. In addition, if (i) this Lease shall have been terminated as a result of Tenant’s default under this Lease beyond the expiration of the applicable cure period, and/or (ii) this Lease shall have been rejected in a bankruptcy or other creditor-debtor proceeding, then Landlord shall have the right at any time thereafter to draw down from the Letter of Credit an amount sufficient to pay any and all damages payable by Tenant on account of such termination or rejection, as the case may be, pursuant to Article 8 hereof. In the event of bankruptcy or other creditor-

14

debtor proceeding against Tenant, all proceeds of the Letter of Credit 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.

4.4.5 Issuing Bank. In the event the Issuing Bank becomes insolvent, or if Landlord reasonably believes the Issuing Bank is financially troubled or at risk of becoming insolvent, or if the Issuing Bank is placed into receivership or conservatorship by the Federal Deposit Insurance Corporation (or any successor or similar entity), or if a trustee, receiver or liquidator is appointed for the Issuing Bank, then, effective as of the date of such occurrence, the Letter of Credit shall be deemed to not meet the requirements of this Section 4.4 and Tenant shall, within ten (10) business days of written notice from Landlord, deliver to Landlord a Substitute Letter of Credit which otherwise meets the requirements of this Section, or, alternatively at Landlord’s discretion, Tenant shall, within suchfive-day period deliver cash to Landlord in the Letter of Credit Amount, which Landlord shall hold as “Security Proceeds” which shall be governed by subject to the provisions of Section 4.4.6 below.

4.4.6 Draws for Failure to Deliver Substitute Letter of Credit. If Tenant fails timely to deliver to Landlord a Substitute Letter of Credit, then Landlord shall have the right, at any time thereafter, without giving any notice to Tenant, to draw down the Letter of Credit and to hold the proceeds thereof (“Security Proceeds”) in a bank account in the name of Landlord, which may be withdrawn and applied by Landlord under the same circumstances and for the same purposes as if the Security Proceeds were a Letter of Credit. Upon any such application of Security Proceeds by Landlord, Tenant shall, within 30 days of written demand therefor, deliver to Landlord an Additional Letter of Credit in the amount of Security Proceeds so applied.

4.4.7 Transferability. Landlord shall be entitled to transfer its beneficial interest under the Letter of Credit or any Security Proceeds in connection with (i) Landlord’s sale or transfer of the Building, or (ii) the addition, deletion or modification of any beneficiaries under the Letter of Credit, and the Letter of Credit shall specifically state on its face that it is transferable by Landlord, its successors and assigns. Tenant agrees to pay Landlord upon demand, as Additional Rent, all costs and fees charged to effect such transfer.

4.4.8 Return of Letter of Credit at End of Term. Within 45 days after the expiration of the term, to the extent Landlord has not previously drawn upon any Letter of Credit or Security Proceeds held by Landlord, Landlord shall return the same to Tenant provided that there is not at such time any continuing default of any of Tenant’s obligations under this Lease.

However in each instance of failure or interruption Landlord shall use reasonable efforts to restore the unavailable service or remedy the condition following written notice from Tenant.

B. Notwithstanding the foregoing, if an event or circumstance (an “Abatement Event”) shall occur that causes an interruption or curtailment, suspension or stoppage of an

16

Essential Service that reasonably prevents Tenant from using the entire Premises, or any material portion thereof, as a result of Landlord’s failure to provide any Essential Service (defined below) required to be provided by Landlord under this Lease, provided that such failure or Landlord’s inability to remedy such event or circumstance is not due to Force Majeure or a cause beyond Landlord’s reasonable control generally affecting other buildings in the vicinity (such as a neighborhood power outage or otheroff-site occurrence) or the act or negligence of Tenant, its employees, vendors, or contractors, or any party claiming by, through or under Tenant then Tenant shall give Landlord notice (an “Abatement Notice”) of any such Abatement Event. If such Abatement Event continues beyond the “Eligibility Period” (defined below), then the Monthly Fixed Rent and monthly charges on account of Operating Costs and Taxes shall be abated entirely or proportionately, as the case may be, after the expiration of the Eligibility Period for such time that Tenant continues to be so prevented from using, and does not use, the Premises or a portion thereof, in the proportion that the rentable area of the portion of the Premises that Tenant is prevented from using, and does not use, bears to the total rentable area of the Premises.

B. Tenant shall, as Additional Rent, reimburse Landlord promptly for Landlord’s reasonableout-of-pocket 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.

Tenant hereby irrevocably authorizes and directs any such subtenant, upon receipt of a written notice from Landlord stating that a default hereunder exists under this Lease, to pay to Landlord the rents and other charges due and to become due under the sublease. The subtenant shall rely upon any such statement and request from Landlord and shall pay such rents and other charges to Landlord without any obligation or right to inquire as to whether such breach exists and notwithstanding any notice from or claim from Tenant to the contrary. Tenant shall have no right or claim against said subtenant, or, until the breach has been cured, against Landlord, for any such rents and other charges so paid by said subtenant to Landlord.

(ii) In the event of a default by Tenant in the performance of its obligations under this Lease that results in a termination of this Lease, Landlord, at its option and without any obligation to do so, may require any subtenant to attorn to Landlord, in which event Landlord shall undertake the obligations

22

of the sublandlord under such sublease from the time of the exercise of said option to the expiration of such sublease; provided, however, Landlord shall not be liable for any prepaid rents or security deposit paid by such subtenant to Tenant or for any other prior defaults or breaches of Tenant as sublandlord under such sublease.

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.

(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 in violation of the provisions of Section 6.2.1 of this Lease, or (c) if any assignment shall be made by Tenant or any guarantor of Tenant for the benefit of creditors, or (d) if Tenant’s leasehold interest shall be taken on execution, or (e) 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 or bonded over within twenty (20) days thereafter, or (f) 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 (g) 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 within sixty (60) 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 and with process of law enter into and upon the Premises or any part thereof in the name of the whole 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/or Landlord may terminate this Lease by sending written notice of termination to Tenant and this Lease shall terminate and come to an end on the date of entry as aforesaid, or on the third (3^rd) day following the giving of such notice as fully and completely as if such date were the date originally fixed for expiration of the Term of this Lease. Tenant will quit and surrender the Premises to Landlord, but shall remain liable as herein provided. Tenant hereby waives all statutory rights to the Premises (including without limitation rights of redemption, if any, granted under any present or future laws to the extent such rights may be lawfully waived). 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. No termination or repossession provided for in this Section 8.1 shall relieve Tenant or any guarantor of Tenant of the liabilities and obligations of Tenant under this Lease, all of which shall survive any such termination or repossession.

8.2 Remedies. A. In the event of termination or repossession, Tenant covenants to pay punctually to Landlord Fixed Rent, Additional Rent and all other sums for which Tenant is obligated in this Lease to pay and 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 preceding sentence, Tenant shall be credited with any amount paid to Landlord as compensation as set forth below in this Section 8.2 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, reasonable attorney’s fees, and expenses of preparing the Premises for such reletting.

B. Landlord may elect to (i) relet the Premises or any part or parts thereof, for a term or terms which may 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/or (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

27

operate or be construed to release or reduce Tenant’s liability as aforesaid. However, Landlord shall use reasonable efforts tore-let the Premises after Tenant vacates the Premises once this Lease is terminated on account of a default by Tenant. For the purposes of this paragraph, marketing of the Premises in a manner similar to the way Landlord markets its other premises in the suburban market shall be deemed to satisfy Landlord’s obligation to use such “reasonable efforts.” In no event shall Landlord be required (i) to solicit or entertain negotiations with any other prospective tenants for the Premises until Landlord obtains full and complete possession of the Premises including, without limitation, the undisputed right tore-let the Premises free of any claim of Tenant, (ii) to lease the Premises to a tenant whose proposed use, in Landlord’s bona fide judgment, would violate any restrictions by which Landlord is bound, (iii) tore-let the Premises before leasing other comparable vacant space in the Building, (iv) to lease the Premises for a rental less than the current fair market rental then prevailing for similar office space in the Building, or (v) to enter into a lease with any proposed tenant that does not have, in Landlord’s reasonable opinion, sufficient financial resources or operating experience to operate the Premises in a manner comparable to other tenants in the Building. In no event, however, shall Tenant’s liability hereunder be diminished or reduced if or to the extent such reasonable efforts of Landlord tore-let are not successful.

C. If this Lease is terminated under any of the provisions contained in Section 8.1, at the election of Landlord, and in lieu of full recovery by Landlord of the sums payable under the foregoing provisions of this Section 8.2 (except for the amount of any rent of any kind accrued and unpaid at the time of termination), Landlord may by written notice to Tenant, elect to recover, and Tenant shall thereupon pay forthwith to Landlord, as compensation, an amount equal to the present value of the amount by which the payments of Fixed Rent and Additional Rent payable for balance of the Term would exceed the fair rental value of the Premises for the balance 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 by Tenant for the balance of the Term.

D. INTENTIONALLY OMITTED.

E. 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 of the termination of this Lease, an amount equal to the maximum allowed by any statute or rule of law in effect at the time when, and governing the proceedings in which, the damages are to be proved, whether or not the amount 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

28

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 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). Tenant agrees it will, upon not less than ten (10) business 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.

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 upon receipt or rejection when mailed to such address postage prepaid, by registered or certified mail, return receipt requested, or on the next business day when delivered to such address by hand 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. Both Landlord and Tenant agree that it will not record this Lease.

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, managers, members or stockholders of Landlord) ever be personally liable for any such liability.

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 (any of the foregoing causes being referred to herein as “Force Majeure”) 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. Tenant’s inability to pay any sums due Landlord hereunder shall in no way be affected or excused by any of the foregoing causes and shall in no event be deemed a Force Majeure event.

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 (and to all mortgagees of which Tenant has notice) specifying the nature of Landlord’s alleged default. Notwithstanding any provision contained herein, in no event

30

shall Landlord ever be liable to Tenant, or any person claiming by, through or under Tenant, for any special, indirect, incidental or consequential damages, or for any lost profits. 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. Landlord and Tenant warrant and represent to the other that it has dealt with no broker in connection with the consummation of this Lease, other than Transwestern RBJ (the “Broker”), and in the event of any brokerage claims, other than by the Broker, against the other party predicated upon prior dealings with the warranting party, the warranting party agrees to defend the same and indemnify and hold the other party harmless against any such claim. Landlord shall pay the Broker a commission in connection with this Lease pursuant to a separate agreement.

10.8 Applicable Law and Construction; Merger; Jury Trial. 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.

Neither Landlord nor Landlord’s agents shall be bound to any representations with respect to the Premises, the Building or the Property except as herein expressly set forth, and all representations, either oral or written, shall be deemed to be merged into this Lease. The titles of the several Articles and Sections contained herein are for convenience only and shall not be considered in construing this Lease. Each of Landlord and Tenant shall and does hereby waive trial by jury in any action, proceeding, or claim brought by or against such party regarding any matter arising out of or in any way connected with this Lease, the relationship of Landlord and Tenant or Tenant’s use or occupancy of the Premises. 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 person or entity named as tenant, the obligations imposed by this Lease upon Tenant shall be joint and several.

10.9 Consents. With respect to any provision of this Lease which either provides or is held to provide that Landlord shall not unreasonably withhold or unreasonably delay any consent or approval, Tenant shall not be entitled to make any claim for, and Tenant hereby expressly waives, any claim for damages, it being understood and agreed that Tenant’s sole remedy therefor shall be an action for specific performance.
