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.

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).

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:

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 Exhibit C-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.

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.

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’s pre-commencement entry. All such work shall be done in accordance with, and Tenant shall comply with, the provisions of Section 6.2.5 hereof.

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.

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:

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

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

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.

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:

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 and non-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.

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.

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 and non-contributory basis.

All such policies shall be obtained from responsible companies having a policy rating of A-; 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.

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.

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.

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.

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:

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.

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.

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.

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-

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 such five-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.

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.

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.

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.

Affirmative Covenants. Landlord covenants with Tenant:

Heat and Air-Conditioning. To furnish to the Premises heat and air-conditioning (reserving the right, at any time, to change energy or heat sources), separately metered for gas and at the direct expense of Tenant as provided in Section 4.2.5 above, sufficient to maintain the Premises at comfortable temperatures (subject to all federal, state, and local regulations relating to the provision of heat). The heat and air-conditioning temperatures will be controlled by Tenant pursuant to the thermostat in the Premises.

Electricity. To furnish to the Premises, separately metered and at the direct expense of Tenant as hereinabove provided, reasonable electricity for Tenant’s Permitted Uses. If Tenant shall require electricity in excess of reasonable quantities for Tenant’s Permitted Uses and if (i) in Landlord’s reasonable judgment, Landlord’s facilities are inadequate for such excess requirements, or (ii) such excess use shall result in an additional burden on the Building utilities systems and additional cost to Landlord on account thereof, as the case may be, (a) Tenant shall, upon demand,

Cleaning; Water. To provide cleaning to the common areas on business days in accordance with cleaning and janitorial standards generally prevailing throughout the term hereof in comparable office buildings within the municipality in which the Building is located (it being agreed cleaning of the Premises is Tenant’s obligation pursuant to subsection 6.1.3 below); and to furnish water for ordinary cleaning, lavatory and toilet facilities..

Elevator; Fire Alarm. To furnish elevator service (once constructed); and to maintain fire alarm systems within the Building.

Repairs. Except as otherwise expressly provided herein, to make such repairs and replacements to the roof, exterior walls, floor slabs and other structural components of the Building, and to the common areas, facilities and plumbing, electrical, heating, ventilating and air-conditioning systems of the Building as may be necessary to keep them in good repair and condition (exclusive of equipment installed by Tenant and except for those repairs required to be made by Tenant pursuant to Section 6.1.3 hereof and repairs or replacements occasioned by any act or negligence of Tenant, its servants, agents, customers, contractors, employees, invitees, or licensees).

Indemnification. Landlord shall save harmless, exonerate and indemnify Tenant, its agents and employees (such agents and employees being referred to collectively as the “Tenant Related Parties”) from and against any and all claims, liabilities or penalties asserted by or on behalf of any person, firm, corporation or public authority on account of injury, death, damage or loss to person or property in or upon the common area of the Property arising out of the gross negligence or intentional misconduct of Landlord, except if the same was caused by the negligence, fault or misconduct of Tenant or the Tenant Related Parties. In respect of all of the foregoing, Landlord shall indemnify Tenant and the Tenant Related Parties from and against all costs, expenses (including reasonable attorneys’ fees), and liabilities incurred in or in connection with any such claim, action or proceeding brought thereon; and, in case of any action or proceeding brought against Tenant or the Tenant Related Parties by reason of any such claim, Landlord, upon notice from Tenant and at Landlord’s expense, shall resist or defend such action or proceeding and employ counsel therefor reasonably satisfactory to Tenant provided that Tenant shall be deemed to have approved counsel provided by Landlord’s liability insurer. The preceding indemnification shall expressly survive the expiration or earlier termination of this Lease.

Interruption. A. Landlord shall be under no responsibility or liability for failure or interruption of any of the above-described utility services, or conditions arising in or about the Property caused by breakage, accident, strikes, repairs, inability to obtain supplies, labor or materials, or for any other causes beyond the control of the Landlord, and in no event for any indirect or consequential damages to Tenant; and failure or omission on the part of the Landlord to furnish any of same for any of the reasons set forth in this paragraph shall not be construed as an eviction of Tenant, actual or constructive, nor entitle Tenant to an abatement of rent, nor render the Landlord liable in damages, nor release Tenant from prompt fulfillment of any of its covenants 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.

Outside Services. In the event Tenant wishes to provide outside services for the Premises over and above those services to be provided by Landlord as set forth herein, Tenant shall first obtain the prior written approval of Landlord (which shall not be unreasonably withheld, delayed or conditioned) for the installation and/or utilization of such services (“Outside services” shall include, but shall not be limited to, cleaning services, television, so-called “canned music” services, security services, catering services and the like.) In the event Landlord approves the installation and/or utilization of such services, such installation and utilization shall be at Tenant’s sole cost, risk and expense.

Access. Subject to Landlord’s security requirements, if any, Tenant shall have access to the Premises, Building and parking area 24 hours per day, 7 days per week (provided Landlord shall have no obligations to ensure such access).

Affirmative Covenants. Tenant covenants at all times during the term and for such further time (prior or subsequent thereto) as Tenant occupies the Premises or any part thereof:

Perform Obligations. To perform promptly all of the obligations of Tenant set forth in this Lease; and to pay when due the Fixed Rent and Additional Rent and all charges, rates and other sums which by the terms of this Lease are to be paid by Tenant.

Repair and Maintenance; Cleaning. To maintain the Premises in neat order and condition and to perform all routine and ordinary repairs to the Premises and to any plumbing, heating, electrical, ventilating and air-conditioning systems located within the Premises and installed by Tenant such as are necessary to keep them in good working order, appearance and condition, as the case may require, reasonable use and wear thereof and damage by fire or by unavoidable casualty only excepted; to keep all glass in windows and doors of the Premises (except glass in the exterior

Compliance with Law. To make all repairs, alterations, additions or replacements to the Premises required by any law or ordinance or any order or regulation of any public authority; to keep the Premises equipped with all safety appliances so required; and to comply with the orders and regulations of all governmental authorities with respect to zoning, building, fire, health and other codes, regulations, ordinances or laws applicable to the Premises, except that Tenant may defer compliance so long as the validity of any such law, ordinance, order or regulations shall be contested by Tenant in good faith and by appropriate legal proceedings, if Tenant first gives Landlord appropriate assurance or security against any loss, cost or expense on account thereof. Notwithstanding the foregoing, however, Tenant shall not be responsible for compliance with any such laws, regulations, or the like requiring (a) structural repairs or modifications; or (b) repairs or modifications to the utility or building service equipment; or (c) installation of new building service equipment, such as fire detection or suppression equipment, unless such repairs, modifications, or installations shall be due to Tenant’s particular manner of use of the Premises (as opposed to office use generally) or required on account of any work done by or on behalf of Tenant.

Indemnification. To indemnify, defend and hold harmless Landlord, its agents (including, without limitation, Landlord’s managing agent), partners, officers, directors, members, trustees, beneficiaries, shareholders, and employees (such parties being referred to collectively as the “Landlord Related Parties”) from and against any and all claims, demands, liabilities, penalties, fines, settlements, damages, loss, costs or expenses resulting from, arising out of, or in any way related to injury, death, damage or loss to person or property in or upon the Premises and the Property arising out of the use or occupancy of the Premises by Tenant or by any person claiming by, through or under Tenant (including, without limitation, all patrons, employees and customers of Tenant), the negligent acts or omissions or intentional misconduct of Tenant or any person claiming by, through or under Tenant, or on account of any breach by Tenant of its obligations under this Lease. or on account of or based upon anything whatsoever done on the Premises, except if the same was caused by the willful negligence, fault or misconduct of Landlord or the Landlord Related Parties. In respect of all of the foregoing, Tenant shall indemnify Landlord and the Landlord Related Parties from and against all costs and expenses (including reasonable attorneys’ fees), of whatever kind or nature incurred in or in connection with any such claim, action or proceeding brought thereon; and, in case of any action or proceeding brought against Landlord or the Landlord Related Parties by reason of any such claim, Tenant, upon notice from Landlord and at Tenant’s expense, shall resist or defend such action or proceeding and employ counsel therefor reasonably satisfactory to Landlord. The preceding indemnification shall expressly survive the expiration or earlier termination of this Lease.

Landlord’s Right to Enter. To permit Landlord and its agents to enter into and examine the Premises at reasonable times and upon no less than twenty-four (24)

Personal Property at Tenant’s Risk. All of the furnishings, fixtures, equipment, effects and property of every kind, nature and description of Tenant and of all persons claiming by, through or under Tenant which, during the continuance of this Lease or any occupancy of the Premises by Tenant or anyone claiming under Tenant, may be on the Premises, shall be at the sole risk and hazard of Tenant and if the whole or any part thereof shall be destroyed or damaged by fire, water, rain or by the leakage or bursting or other defect of water pipes, steam pipes, or other pipes, sprinklers, lighting fixtures or other cause by theft, any acts or omissions of any other tenant of the Property, or from any other cause, no part of said loss or damage is to be charged to or to be borne by Landlord, except that Landlord shall in no event be indemnified or held harmless or exonerated from any liability to Tenant or to any other person, for any injury, loss, damage or liability to the extent prohibited by law.

Payment of Landlords Cost of Enforcement.

At the expiration of the term or earlier termination of this Lease: to surrender all keys to the Premises; to remove all of its trade fixtures and personal property in the Premises; to deliver to Landlord stamped architectural plans showing the Premises at yield up (which may be the initial plans if Tenant has made no installations after the Commencement Date); to remove such installations made by it as Landlord may request (including computer and telecommunications wiring and cabling, it being understood that if Tenant leaves such wiring and cabling in a useable condition, Landlord, although having the right to request removal thereof, is less likely to so request) and all Tenant’s signs wherever located; to repair all damage caused by such removal and to yield up the Premises (including all installations and improvements made by Tenant except for trade fixtures and such of said installations or improvements as Landlord shall request Tenant to remove), broom-clean and in the same good order and repair in which Tenant is obliged to keep and maintain the Premises by the provisions of this Lease, normal wear and tear and casualty excepted. Tenant, at the time of making any installation, alteration, or improvement, may request in writing Landlord’s written permission to leave the same in the Premises at the expiration of earlier termination of this Lease. Landlord shall, after receipt of Tenant’s request, notify Tenant in writing as to whether such installation, alteration or improvement may or may not remain in the Premises at the expiration or earlier termination of this Lease. If Landlord so notifies Tenant that such installation, alteration, or improvement may remain in the Premises at the expiration or earlier termination of this Lease, Landlord shall thereafter not be permitted to request or require that the same be removed at the expiration or earlier termination of the Lease. Notwithstanding anything to the contrary contained herein, Tenant shall have no obligation to remove any of Landlord’s Work. Any property not so removed shall be deemed abandoned and, if Landlord so elects, deemed to be Landlord’s property, and may be retained or removed and disposed of by Landlord in such manner as Landlord shall determine and Tenant shall pay Landlord the entire cost and expense incurred by it in effecting such removal and disposition and in making any incidental repairs and replacements to the Premises and for use and occupancy during the period after the expiration of the term and prior to its performance of its obligations under this subsection 6.1.9. Tenant shall further indemnify Landlord against all loss, cost and damage resulting from Tenant’s failure and delay in surrendering the Premises as above provided.

Rules and Regulations. To comply with the Rules and Regulations set forth in Exhibit F, and with all reasonable Rules and Regulations of general applicability to all tenants of the Building hereafter made by Landlord, of which Tenant has been given notice; Landlord shall not be liable to Tenant for the failure of other tenants of the Building to conform to such Rules and Regulations, but Landlord shall not enforce any Rules and Regulations against Tenant in a discriminatory manner. Tenant shall cause all parties performing work on behalf of Tenant in or about the Premises and Building to comply with the Construction Rules and Regulations attached hereto as Exhibit F-1.

Upon not less than ten (10) business days’ prior written request by Landlord, to execute, acknowledge and deliver to Landlord a statement in writing, which may be in the form attached hereto as Exhibit G or in another form reasonably similar thereto, or such other form as Landlord may provide from time to time, certifying all or any of the following: (i) that this Lease is unmodified and in full force and effect, (ii) whether the term has commenced and Fixed Rent and Additional Rent have become payable hereunder and, if so, the dates to which they have been paid, (iii) whether or not Landlord is in default in performance of any of the terms of this Lease, (iv) whether Tenant has accepted possession of the Premises, (v) whether Tenant has made any claim against Landlord under this Lease and, if so, the nature thereof and the dollar amount, if any, of such claim, (vi) whether there exist any offsets or defenses against enforcement of any of the terms of this Lease upon the part of Tenant to be performed, and (vii) such further information with respect to the Lease or the Premises as Landlord may reasonably request. Any such statement delivered pursuant to this subsection 6.1.11 may be relied upon by any prospective purchaser or mortgagee of the Premises, or any prospective assignee of such mortgage. Tenant shall also deliver to Landlord such financial information as may be reasonably required by Landlord to be provided to any mortgagee or prospective purchaser of the Premises. If Tenant fails to deliver the estoppel certificate within the required time period, and such failure continues for an additional five (5) days following a second written request from Landlord, then Tenant shall be obligated to pay to Landlord, as Additional Rent within twenty (20) days of demand, a fee in the amount of $500.00 per day for each day that Tenant fails to deliver the requested estoppel in the period beginning on the day after the expiration of the initial 10-day period, and ending on the day Tenant actually delivers the estoppel.

Assignment and Subletting. A. Not to assign, transfer, mortgage or pledge this Lease or to sublease (which term shall be deemed to include the granting of concessions and licenses and the like) all or any part of the Premises or permit this Lease or the leasehold estate hereby created or any other rights arising under this Lease to be assigned, transferred, pledged or encumbered, in whole or in part, whether 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, or as otherwise permitted hereunder for Permitted Transfers without Landlord’s consent. In the event Tenant desires to assign this Lease or sublet any portion or all of the Premises other than to a Permitted Transferee, 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. Except with respect to Permitted Transfers, Landlord may terminate this Lease in the case of a proposed assignment, or suspend this Lease pro tanto for the period and with respect to the space involved in the case of a proposed subletting, by giving written notice of termination or suspension to Tenant, with such termination or suspension to be effective as of the effective date of such assignment or subletting. If Landlord does not so terminate or suspend, Landlord’s consent shall not be unreasonably withheld, delayed or conditioned to an assignment or to a subletting, provided that the following conditions are met:

the assignee or subtenant shall use the Premises only for the Permitted Uses;

the Premises shall not be subject to more than one (1) sublease at any time, it being understood that multiple sublets of the Premises are not permitted;

the proposed assignee or subtenant provides a representation and warranty regarding the Patriot Act provisions set forth in this Lease.

Tenant hereby assigns and transfers to Landlord all of Tenant’s interest in all rentals and income arising from any sublease of all or a portion of the Premises heretofore or hereafter made by Tenant, and Landlord may collect such rent and income and apply same toward Tenant’s obligations under this Lease; provided, however, that until a default by Tenant hereunder shall occur under this Lease, Tenant may, except as otherwise provided in this Lease, receive, collect and enjoy the rents accruing under such sublease. Landlord shall not, by reason of this or any other assignment of such sublease to Landlord, nor by reason of the collection of the rents from a subtenant, be deemed liable to the subtenant for any failure of Tenant to perform and comply with any of Tenant’s obligations to such subtenant under such sublease. 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.

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

Not to injure, deface or otherwise harm the Premises; nor commit any nuisance; nor permit in the Premises any vending machine (except such as is used for the sale of merchandise to employees and invitees of Tenant) or inflammable fluids or chemicals (except such as are customarily used in connection with standard office equipment); nor permit any cooking to such extent as requires special exhaust venting; nor permit the emission of any reasonably objectionable noise or odor; nor make, allow or suffer any waste; nor make any use of the Premises which is improper, offensive or contrary to any law or ordinance or which will invalidate any of Landlord’s insurance; nor conduct any auction, fire, “going out of business” or bankruptcy sales.

Hazardous Wastes and Materials. Not to cause or permit any Hazardous Materials to be used, handled, generated, stored or disposed of by Tenant, or persons or entities acting by, through, or on behalf of Tenant, on, under or above, or transported to or from, the Premises and/or the Property (collectively, “Hazardous Materials Activities”). Nothing contained herein shall be deemed to prevent Tenant from using de minimus quantities of (a) commercially available cleaners and office supplies which are customarily used in the ordinary course of first-class business office operations which cleaners and/or office supplies contain Hazardous Materials and/or (b) methanol, acetone, and isopropyl alcohol (the items in [b] collectively the “Tenant Specific Cleaning Items”) it being agreed Tenant may add items to the Tenant Specific Cleaning Items provided the same (i) are customarily used for cleaning optics, (ii) do not require any permit, consent, license, approval or other action from any governmental, quasi-governmental or regulatory body or agency (or similar entity), and (iii) Tenant gives Landlord reasonable prior notice of such new item; provided that, Tenant shall use such cleaners and/or office

Floor Load; Heavy Equipment. Not to place a load upon any floor of the Premises exceeding the floor load per square foot area which such floor was designed to carry and which is allowed by law. Landlord reserves the right to prescribe the weight and position of all heavy business machines and equipment, including safes, which shall be placed so as to distribute the weight. Business machines and mechanical equipment which cause vibration or noise shall be placed and maintained by Tenant at Tenant’s expense in settings sufficient to absorb and prevent vibration, noise and annoyance. Tenant shall not move any safe, heavy machinery, heavy equipment, freight or fixtures into or out of the Premises except in such manner and at such time as Landlord shall in each instance authorize.

Installation, Alterations or Additions. Not to make any installations, alterations or additions in, to or on the Premises nor to permit the making of any holes (other than in connection with hanging pictures or securing furniture and fixtures) in the walls, partitions, ceilings or floors nor the installation or modification of any locks or security devices without on each occasion obtaining the prior written consent of Landlord, and then only pursuant to plans and specifications approved by Landlord in advance in each instance, which approval shall not be unreasonably withheld, delayed or conditioned. Landlord shall give Tenant notice, in reasonable detail, of any objections or concerns Landlord may have with respect to any proposed

Abandonment. Not to abandon the Premises during the term, it being understood and agreed that vacancy of the Premises shall not be construed as abandonment so long as all of Tenant’s other obligations under this Lease, including payment of rent and all other sums owing to Landlord, continue to be timely performed and reasonable and diligent measures are taken by Tenant to manage the vacant space.

Signs. Not without Landlord’s prior written approval to paint or place any signs or place any curtains, blinds, shades, awnings, aerials, or the like, visible from outside the Premises. Landlord shall, at Landlord’s expense, provide Tenant with Building-standard signage on the tenant directory in the Building lobby.

Parking and Storage. Not to permit any storage of materials outside of the Premises; nor to permit the use of the parking areas for either temporary or permanent storage of trucks; nor permit the use of the Premises for any use for which heavy trucking would be customary.

Termination. In the event that the Premises or the Building, or any material part thereof, shall be taken by any public authority or for any public use, or shall be destroyed or damaged by fire or casualty, or by the action of any public authority, then this Lease may be terminated at the election of Landlord. Such election, which may be made notwithstanding the fact that Landlord’s entire interest may have been divested, shall be made by the giving of notice by Landlord to Tenant within sixty (60) days after the date of the taking or casualty. In the event that the Premises are substantially destroyed or damaged by fire or casualty, or by the action of public authority during the original term, and, in the reasonable opinion of an independent architect or engineer selected by Landlord, cannot be repaired or restored within two hundred and seventy (270) days from the date the repair or restoration work would commence, then this Lease may be terminated at the election of Tenant, which election shall be made by the giving of notice to Landlord within thirty (30) days after the date the opinion of the architect or engineer is made available to the parties, which notice shall specify the effective date of termination, which shall not be less than thirty (30) nor more than sixty (60) days after the date of Tenant’s termination notice.

Restoration. If Landlord 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 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. Notwithstanding anything herein to the contrary, if Landlord shall not have restored the Premises within two hundred and seventy (270) days from the date such restoration work commenced (subject to Section 10.5 hereof), and such failure is not a result of delays caused by Tenant, 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.

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. 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. Nothing contained herein shall be construed to prevent Tenant from prosecuting in any condemnation proceedings a claim for relocation expenses, provided that such action shall not affect the amount of compensation otherwise recoverable by Landlord from the taking authority.

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 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.

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.

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.

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.

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.

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

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.

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.

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.

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.

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.

Lease not to be Recorded. Both Landlord and Tenant agree that it will not record this Lease.

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.

Force Majeure. 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.

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

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.

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.

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.

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.

In the event the Tenant is a corporation, partnership or limited liability company, Tenant hereby represents and warrants that: the Tenant is a duly constituted corporation, partnership or limited liability company, as the case may be, qualified to do business in the Commonwealth of Massachusetts; that the person executing this Lease is duly authorized to execute and deliver this Lease on behalf of said corporation(s), partnership(s) or limited liability company(ies); and that the by-laws of Tenant authorize to enter into this Lease.
