Subject to the terms and conditions set forth herein, Landlord hereby leases and demises to Tenant and Tenant hereby leases from Landlord the Premises identified in Article 1 above for a term (“Term”) commencing on the Commencement Date and ending on the Expiration Date set forth in Article 1, unless sooner terminated as provided herein. Such date shall be confirmed by execution of the Commencement Date Confirmation in the form as set forth in Exhibit K, which Tenant shall execute and return to Landlord within fifteen (15) days after receipt thereof.  Tenant shall be permitted to extend the original Term hereof in accordance with the provisions of Exhibit F attached hereto.
ARTICLE 3. 
 
RENT
A.    Monthly Base Rent.  Commencing on the Rent Commencement Date, Tenant shall pay Monthly Base Rent in advance on or before the first (1st) day of each month of the Term without demand, setoff or deduction except as otherwise expressly set forth in this Lease.  If the Term shall end on a day other than the first (1st) day of a month, the Monthly Base Rent for the last partial month of the Term shall be prorated on a per diem basis. 
B.    Additional Rent.  All costs and expenses, other than Monthly Base Rent, which Tenant assumes or agrees to pay and any other sum payable by Tenant pursuant to this Lease, including, without limitation, its Pro Rata Share of Taxes and Operating Expenses (both as hereinafter defined), shall be deemed Additional Rent.
C.    Rent.  Monthly Base Rent, Additional Rent, and any other amounts of every nature which Tenant is or becomes obligated to pay Landlord under this Lease are herein referred to collectively as “Rent,” and all remedies applicable to the nonpayment of Rent shall be applicable thereto.  Landlord may apply payments received from Tenant to any obligations of Tenant then accrued and due, without regard to such obligations as may be designated by Tenant.
D.    Place of Payment, Late Charge, Default Interest.  Rent and other charges required to be paid under this Lease, no matter how described, shall be paid by Tenant to Landlord without offset, deduction, credit or the like, at the Building Manager’s address listed in Article 1, or to such other person and/or address as Landlord may designate in writing.  In the event Tenant fails to pay Rent due under this Lease within ten (10) business days of the due date of said Rent, Tenant shall pay to Landlord a late charge of three percent (3%) of the amount overdue; provided, however, that no such late charge will be charged for the first (1st) late payment in any rolling twelve (12) month period during the Term.  Any Rent not paid within ten (10) business days of the due date of said Rent shall also bear interest at the Default Rate from and after the date due through the date on which Landlord receives payment.  This provision shall in no way be construed to modify Tenant’s obligation to pay Rent on or before the first (1st) day of the month.
ARTICLE 4. 
 
TAXES AND OPERATING EXPENSES
A.    Payment of Taxes and Operating Expenses.  Commencing upon the expiration of the Base Year (i.e., January 1, 2017 for Operating Expenses and July 1, 2016 for Taxes) and for each year, or portion thereof, thereafter during the Term (hereinafter each referred to as a “Comparison Year”), Tenant shall pay Landlord an amount equal to Tenant’s Pro Rata Share of increases in Operating Expenses and Taxes over the Operating Expenses and Taxes for the relevant Base Year (collectively, the “Escalation Increase”).  Landlord shall have the right to change the Comparison Year from a calendar year to a fiscal year from time to time (or vice versa), provided that equitable adjustment is made so that Tenant shall not be charged more than once for the same period.  Commencing with the first (1st) month of the first (1st) Comparison Year and on the first (1st) day of each month thereafter during the original Term or any extension thereof, Tenant shall pay Escalation Increases to Landlord, as Additional Rent due concurrently with Monthly Base Rent, in installments equal to one-twelfth (1/12) of Landlord’s commercially reasonable estimate of any projected Escalation Increase for the particular Comparison Year (the “Estimated Escalation Increase”).  A final adjustment (“Escalation Reconciliation”) shall be made by Landlord and Tenant as soon as practicable (but in any event within one hundred twenty (120) days) following the end of each Comparison Year.  In computing the Estimated Escalation Increase for any particular Comparison Year, Landlord shall take into account any prior increases in Tenant’s Pro Rata Share of Taxes and Operating Expenses. Landlord’s Estimated Escalation Increase for Taxes in any Comparison Year will not exceed the Taxes then reflected on Landlord’s real estate tax bill from the City of Boston.  If any Estimated Escalation Increase is less than the Estimated Escalation Increase for the immediately preceding Comparison Year, the payments to be paid by Tenant for the new Comparison Year attributable to said Estimated Escalation Increase shall be decreased accordingly; provided, however, in no event will the Rent paid by Tenant hereunder ever be less than the Monthly Base Rent.  
B.    Escalation Reconciliation.  Within one hundred twenty (120) days after the last day of such Comparison Year, Landlord shall submit to Tenant a statement setting forth the actual Escalation Increase for the Comparison Year which was just completed and the Estimated Escalation Increase for the current Comparison Year (the “Escalation Statement”).  To the extent that the actual Escalation Increase exceeds the Estimated Escalation Increase paid by Tenant for the Comparison Year just completed, Tenant shall pay Landlord the difference, in cash within thirty (30) days following receipt by Tenant from Landlord of the Escalation Statement.  If the actual Escalation Increase for the Comparison Year just completed is less than the Estimated Escalation Increase paid by Tenant for such year, then Tenant shall receive a credit on future Rent owing under this Lease (or cash, if there is no future Rent owing hereunder).  Until Tenant receives the Escalation Statement, Tenant’s Estimated Escalation Increases for the new Comparison Year shall continue to be paid at the rate being paid for the particular Comparison Year just completed.  Tenant shall commence payment to Landlord of the Estimated Escalation Increase for the then current Comparison Year, beginning on the first (1st) day of the month following the month in which Tenant receives the applicable Escalation Statement. Any amount described in this Article 4 that is not billed to Tenant within two (2) years after the end of the Comparison Year in question shall be deemed forever waived by Landlord, and Tenant shall have no further obligation therefor.
C.    Changes in Escalations During the Lease Year.  In addition to the above, if, during any particular Comparison Year, there is a change in the information upon which the then current Estimated Escalation Increase is based, Landlord shall be permitted (but in no event more than one time in any calendar year) to revise such Estimated Escalation Increase by notifying Tenant, and such adjustment shall be made in the payment of Estimated Escalation Increases, commencing on the first day of the month following the delivery of such notice to Tenant.  When the Escalation Statement for the Comparison Year in which this Lease terminates is delivered to the Tenant, Tenant shall pay to Landlord within thirty (30) days after Landlord’s delivery of the same, any additional amounts due as calculated pursuant to this Article 4.  Landlord’s and Tenant’s responsibilities with respect to Escalation Increases shall survive the expiration or early termination of this Lease.
If the Building is less than ninety-five percent (95%) occupied during the Base Year or any particular Comparison Year, Landlord shall adjust those particular components of Operating Expenses which are affected by Building occupancy for the Base Year or the particular Comparison Year, or portion thereof, as the case may be, to reflect an occupancy of not less than ninety-five percent (95%) of all such rentable area of the Building.  
D.    Disputes Over Taxes or Operating Expenses.  If Tenant disputes the amount of an Estimated Escalation Increase or an actual Escalation Increase, Tenant shall give Landlord written notice of such dispute within one hundred fifty (150) days after Landlord delivers the applicable Escalation Statement.  Tenant’s failure to give such notice shall waive its right to audit the amounts so determined.  Tenant shall not be entitled to audit the foregoing amounts if an Event of Default by Tenant then exists and remains uncured.  Said audit will be conducted at Tenant’s expense by a certified public accountant or by a qualified and reputable real estate professional, in either case paid on an hourly basis unrelated to actual savings identified.  Tenant shall only be permitted to conduct such a review during regular business hours at Landlord’s office, after Tenant gives Landlord twenty (20) days prior written notice, and no more than once with respect to any one Comparison Year.  If such review discloses that the charges actually incurred by Landlord are less than those used by Landlord in calculating Escalation Increases, then Landlord shall reimburse Tenant for the amount Tenant paid in excess of Tenant’s actual Escalation Increases.  If any such review discloses that the charges for Operating Expenses or Taxes used by Landlord in calculating the Escalation Increases exceeds the actual charges for Operating Expenses and Taxes (the “Actual Expenses”) by five percent (5%) or more of the Actual Expenses for such Comparison Year, then Landlord shall pay the reasonable costs of such review.  If Tenant does not review Landlord’s records within two hundred seventy (270) days after receipt of the Escalation Statement, Tenant shall have no further right to review Landlord’s records for the applicable period.  No subtenant shall have the right to conduct an audit and no assignee shall conduct an audit for any period during which such assignee was not in possession of the Premises.
In the event Tenant elects to exercise its audit rights hereunder, Tenant shall nevertheless timely pay Landlord the amount of the prior year’s Escalation Reconciliation and continue to pay Estimated Escalation Increases (without prejudice to Tenant’s position) as set forth in the then applicable Escalation Statement until the parties have agreed as to the appropriate adjustment.  
E.    Building as Part of Multi-Building Development.  Tenant acknowledges that the Building is part of the Project.  As a result thereof, any Operating Expenses and Taxes attributable in part to the Building and in part to other portions of the Project, including, without limitation, the Building Common Areas (as hereinafter defined), shall be allocated to the Building and said other portions of the Project pursuant to the Declaration or any other applicable reciprocal easement agreement and otherwise on an equitable basis.   In addition, any Operating Expenses and Taxes attributable in part to the Office Component and in part to the Retail Component shall be allocated to the Office Component or the Retail Component, as the case may be, on an equitable basis. 
F.    Tenant’s Taxes.  Tenant shall pay, prior to delinquency, all taxes assessed against or levied upon trade fixtures, furnishings, equipment and all other personal property of Tenant located in the Premises and any excise, sales or use taxes related to Tenant’s business.  In the event any or all of Tenant’s trade fixtures, furnishings, equipment and other personal property shall be assessed and taxed with property of Landlord, or if the cost or value of any leasehold improvements in the Premises exceeds the cost or value of a standard build out for general office use and, as a result, real property taxes for the Building are increased, Tenant shall pay to Landlord its share of such taxes within thirty (30) days after delivery to Tenant by Landlord of a statement in writing setting forth the amount of such taxes applicable to Tenant’s property or above-standard improvements.  Tenant shall pay directly to the party or entity entitled thereto all business license fees, gross receipts taxes and similar taxes and impositions which may from time to time be assessed against or levied upon Tenant, as and when the same become due and before delinquency.  Notwithstanding anything to the contrary contained herein, any sums payable by Tenant under this Article 4 shall not be included in the computation of “Taxes.”
ARTICLE 5. 
 
DELIVERY OF PREMISES, TENANT’S WORK, ALTERATIONS AND ADDITIONS
A.     Delivery of Premises.  On the next business day following the execution and delivery of this Lease by Landlord and Tenant, Landlord shall deliver, and Tenant shall accept, the Premises in the “Delivery Condition,” which shall mean that the Premises will be delivered vacant and broom clean, free of construction debris, tools and other personal property, and free of any unlawful Hazardous Materials (as hereinafter defined), but otherwise in their current “as is,” “where is” condition.  Landlord shall have no obligation to construct any improvements in and to the Premises or to perform any other work therein, the parties acknowledging and agreeing that Tenant shall be solely responsible for improving the Premises as provided in Article 5.B. below and Exhibit B attached hereto, provided that the foregoing shall in no event derogate from or diminish Landlord’s ongoing repair and maintenance obligations under this Lease.  Notwithstanding anything contained herein to the contrary, Landlord hereby represents and warrants to Tenant that, as of the Commencement Date, the Common Areas of the Building and the Base Building Condition of the Premises comply with all applicable Laws, including, without limitation, the ADA (as hereinafter defined) and all other applicable laws and rules governing access to and use of facilities by people with disabilities, including the Massachusetts Architectural Access Board regulations.  The “Base Building Condition” is as described on Exhibit E attached hereto. 
B.    Tenant’s Work.  On and after the Commencement Date, Tenant shall be entitled to construct certain initial improvements in and to the Premises and prepare same for occupancy in accordance with the terms and conditions of the work exhibit attached hereto as Exhibit B (collectively, “Tenant’s Work”).
C.    Alterations.  Except as otherwise provided in Article 5.B. above and Exhibit B attached hereto, Tenant shall make no alterations or additions to the Premises (“Alterations”) without the prior written consent of Landlord, which consent may be withheld in Landlord’s sole discretion as to Alterations which adversely affect or impair the structural integrity of or the efficient and proper operation of the operating systems of the Building, and which consent shall not be unreasonably withheld, delayed or conditioned as to all other Alterations.  Any Alterations shall only be performed by contractors or mechanics approved by Landlord in writing (which approval shall not be unreasonably withheld, conditioned or delayed), and only upon the approval by Landlord in writing of fully detailed and dimensioned plans and specifications pertaining to the Alterations in question (to the extent such plans and/or specifications would customarily be prepared for work of such nature), to be prepared and submitted by Tenant, at its sole cost and expense, which approval shall not be unreasonably withheld, conditioned or delayed.  Tenant shall, at its sole cost and expense, obtain all necessary approvals and permits pertaining to any Alterations approved by Landlord.  Tenant hereby indemnifies, defends and agrees to hold Landlord free and harmless from all liens and claims of lien, and all other liability, claims and demands arising out of any work done or material supplied to the Premises by or at the request of Tenant in connection with any Alterations.  If permitted Alterations are made by, on behalf of, or at the request of, Tenant, they shall be made at Tenant’s sole cost and expense and shall be and become the property of Landlord, except that Landlord may, by written notice to Tenant given at the time of approval of such Alterations, require Tenant, at Tenant’s expense, to remove all partitions, counters, railings and other Alterations installed by Tenant, and to repair any damages to the Premises caused by such removal.  Unless Landlord notifies Tenant in writing of such removal obligation at the time of Landlord’s approval of the plans and specifications therefor in accordance with the terms and conditions of Exhibit B attached hereto, Tenant shall not be required to remove any alterations or improvements made to prepare the Premises for Tenant’s initial occupancy; provided, however, that Landlord agrees that Tenant shall not be obligated to remove any of the improvements conceptually shown on the space plan hereto as Exhibit B-1, subject to the terms and conditions of Exhibit B attached hereto.  Any and all costs attributable to or related to the applicable building codes of the City of Boston (or any other authority having jurisdiction over the Building) arising from Tenant’s plans, specifications, improvements, Alterations or otherwise shall be paid by Tenant at its sole cost and expense.  With regard to repairs, Alterations or any other work arising from or related to this Article 5, Landlord shall be entitled to receive a commercially reasonable administrative/supervision fee, not to exceed three percent (3%) of the so-called “hard” costs of any such work, to compensate Landlord for costs and expenses arising from Landlord’s review and approval processes. 
D.    Liens.  Tenant will not cause or permit any mechanic’s, materialman’s or similar liens or encumbrances to be filed or exist against the Premises or the Building or Tenant’s interest in this Lease in connection with work done under this Article 5 or in connection with any other work, and Tenant agrees to defend, indemnify and hold harmless Landlord from and against any such lien or claim or action thereon, together with costs of suit and reasonable attorneys’ fees incurred by Landlord in connection with any such claim or action.  Tenant shall remove any such lien or encumbrance by bond or otherwise within twenty (20) days from the date of receipt of notice of its existence.  If Tenant fails to do so, Landlord may, without being responsible to investigate the validity or lawfulness of the lien, pay the amount or take such other action as Landlord deems necessary to remove any such lien or encumbrance or require that Tenant deposit with Landlord in cash and lawful money of the United States, one hundred ten percent (110%) of the amount of such claim, which sum may be retained by Landlord until such claim shall have been removed of record or until judgment shall have been rendered on such claim and such judgment shall have become final, at which time Landlord shall have the right to apply such deposit in discharge of the judgment on said claim and any costs, including attorneys’ fees incurred by Landlord, and shall remit the balance thereof to Tenant.  The amounts so paid and costs incurred by Landlord shall be deemed Additional Rent under this Lease and payable in full upon demand, but shall be applied only to the lien or judgment in question, and any excess will be refunded to Tenant.
E.    Compliance with ADA.  Landlord represents and warrants to Tenant that, as of the Commencement Date hereof, the Building and the Premises are in compliance with ADA (as defined below). Landlord and Tenant agree that responsibility for compliance with the Americans With Disabilities Act of 1990, as amended (the “ADA”) shall be allocated as follows: (i) Landlord shall be responsible for compliance with the provisions of Title III of the ADA for all Building Common Areas, including exterior and interior areas of the Building not included within the Premises or the premises of other tenants; (ii) Landlord shall be responsible for compliance with the provisions of Title III of the ADA for any construction, renovations, alterations and repairs made within the Premises if such construction, renovations, alterations or repairs are made by Landlord for the purpose of improving the Building generally; and (iii) Tenant shall be responsible for compliance with the provisions of Title III of the ADA for any construction, renovations, Alterations and repairs made within the Premises if such construction, renovations, Alterations and repairs are made by Tenant, its employees, agents or contractors, at the direction of Tenant or done pursuant to final construction plans and specifications prepared or provided by Tenant or Tenant’s architect or space planner.
 F.    Labor Covenant.    As a condition precedent to any proposed construction work or Alteration, Tenant shall deliver to Landlord evidence satisfactory to Landlord that Tenant shall cause such construction, alteration or service contract work to be performed solely by contractors whose employees are represented by unions and such employment will conform to the traditional craft jurisdictions in the area (the “Labor Covenant”).  Tenant shall include the Labor Covenant in each of its contracts for such construction or alteration work and in each of its service contracts for any maintenance, repair and services relating to, or to be performed for the benefit of, the Premises.  Tenant shall also provide such evidence as Landlord may reasonably require, from time to time during the course of such construction or alteration work or the performance of such services, that the Labor Covenant is being fully and faithfully observed and Tenant shall include the obligation to provide such evidence in each contract entered into by Tenant for such construction or alteration work or service being provided to the Premises.  Tenant further agrees that it shall incorporate the foregoing requirements in any sublease of the Premises. Tenant improvement or Alteration work requiring specialized skills that are not available through unionized contractors may be exempted from the Labor Covenant, subject to prior approval by Landlord.

G.    Building Sustainability Strategies.  Landlord has received LEED-Core and Shell Gold Certification, a rating established by the U.S. Green Building Council.  A memorandum outlining Landlord’s “Sustainable Design Strategies” is attached hereto as Exhibit I.    

ARTICLE 6. 
 
TENANT’S USE, RESTRICTIONS AND COMPLIANCE WITH LAWS
A.    Tenant’s Use.  Tenant shall use the Premises for the Permitted Use as provided in Article 1 above, and for no other purpose whatsoever, subject to and in compliance with all other provisions of this Lease, including without limitation the Building’s Rules and Regulations attached as Exhibit D hereto.  Tenant and its invitees shall also have the non-exclusive right, along with other tenants of the Building, others authorized by Landlord, and others having the right to the use thereof, to use the Building Common Areas subject to the Project Documents and such rules and regulations as Landlord may impose from time to time in its sole discretion provided the same are enforced in a non-discriminatory manner.  Landlord makes no representation that the Premises are suitable for Tenant’s purposes.
B.    Tenant’s Restrictions.  Tenant shall not at any time use or occupy, or suffer or permit anyone to use or occupy, the Premises or do or permit anything to be done in the Premises which: (a) causes or is liable to cause injury to persons, to the Building or its equipment, facilities or systems; (b) impairs the character, reputation or appearance of the Building as a first class office building; (c) impairs the proper and economic maintenance, operation and repair of the Building or its equipment, facilities or systems; or (d) would invalidate or increase the cost of any fire and extended coverage insurance policy covering the Building and/or the property located therein.  Tenant shall comply with all rules, orders, regulations and requirements of any organization which sets out standards and requirements commonly referred to by major fire insurance underwriters. Landlord shall notify Tenant if Landlord reasonably believes that Tenant’s use of the Premises is in violation of any such standard or requirement. Tenant shall promptly, upon demand, reimburse Landlord for any additional premium charges for any such insurance policy assessed or increased by reason of Tenant’s failure to comply with the provisions of this Article 6.
C.    Tenant’s Compliance with Laws.  Tenant shall, at Tenant’s sole cost and expense, keep and maintain the Premises, its use thereof and its business in compliance with all Laws now in force or which may hereafter be in force or effect.  Tenant shall comply with all Laws relating to the Premises and Tenant’s use or occupancy thereof, including without limitation Laws in connection with the health, safety and building codes, and any permit or license requirements. Tenant shall not be required to make any alterations to the Premises in order to comply with laws or codes that are applicable to the operation and maintenance generally of a commercial rental property such as the Project, as opposed to Tenant’s specific use of the Premises or any Alterations or other work by Tenant.  
ARTICLE 7. 
 
SERVICES
A.    Climate Control.  Landlord shall furnish heat or air conditioning to the Premises during Normal Business Hours of the Building as set forth in Article 1, as required in Landlord’s reasonable judgment for the comfortable use and occupancy of the Premises and otherwise in accordance with the standards attached hereto as Exhibit J (such standards being referred to herein as “OTIS” or “OTIS standards”).  If Tenant requires heat or air conditioning at any other time (“After Hours Services”), Landlord shall use reasonable efforts to furnish such After Hours Services upon at least twenty-four (24) hours advance notice by Tenant, and Tenant shall pay Landlord, as Additional Rent, the then current rate for such After Hours Services that is applicable to office tenants of the Building generally.  The current estimated rate for After Hours Services is Fifty Dollars ($50.00) per hour, which rate is subject to change from time to time in Landlord’s sole, but reasonable discretion.
The performance by Landlord of its obligations under this Article 7 is subject to Tenant’s compliance with the terms of this Lease regarding any connected electrical load reasonably established by Landlord, and Landlord shall promptly notify Tenant of any respect in which Landlord reasonably believes Tenant is not so complying.  Tenant shall not use the Premises or any part thereof in a manner exceeding the heating, ventilating or air-conditioning (“HVAC”) design conditions (including any occupancy or connected electrical load conditions) set forth in OTIS, including the rearrangement of partitioning which may interfere with the normal operation of the HVAC equipment, or the use of computer or data processing machines or other machines or equipment in excess of the capacities (if any) and standards set forth in OTIS.  If any such use of the Premises by Tenant requires changes in the HVAC or plumbing systems or controls servicing the Premises or portions thereof in order to provide comfortable occupancy in accordance with OTIS standards, such changes may be made by Landlord at Tenant’s expense, and Tenant agrees to promptly pay any such amount to Landlord as Additional Rent.
If Tenant shall install supplemental HVAC equipment in the Premises to serve its needs, chilled water/condenser water shall be made available to Tenant in accordance with OTIS standards.
B.    Elevator Service.  Landlord, during Normal Business Hours of the Building, shall furnish passenger and freight elevator service to Tenant to be used in common with others.  At least one (1) passenger elevator shall remain in service during all other hours.  Landlord may designate a specific elevator for use as a service elevator.
C.    Janitorial Services.  Landlord shall provide janitorial and cleaning services to the Premises, substantially as described in Exhibit D attached hereto.  Tenant shall pay to Landlord within thirty (30) days after receipt of an invoice therefor the actual and reasonable costs incurred by Landlord for (i) any cleaning of the Premises in excess of the specifications in Exhibit D for any reason, including, without limitation, cleaning required because of (A) unreasonable misuse or neglect on the part of Tenant or Tenant’s agents, contractors, invitees, employees and customers, (B) the use of portions of the Premises for special purposes requiring greater or more difficult cleaning work than office areas, (C) unusual quantities of interior glass partitions or interior glass surfaces, and (D) non-building standard materials or finishes installed by Tenant or at its request; and (ii) removal from the Premises of any refuse and rubbish of Tenant in excess of that ordinarily accumulated in general office occupancy or at times other than Landlord’s standard cleaning times as reflected on such Exhibit D.
D.    Water and Electricity.  Landlord shall make available domestic water in reasonable quantities to the Building Common Areas and cause electric service sufficient for lighting the Premises and for the operation of Ordinary Office Equipment.  “Ordinary Office Equipment” shall mean equipment not exceeding the standards and capacities set forth in OTIS.  Landlord shall have the exclusive right to make any replacement of lamps, fluorescent tubes and lamp ballasts in the Premises (provided, however, that replacements of specialty lighting shall be at Tenant’s sole cost and expense).  Landlord may adopt a system of re-lamping and ballast replacement periodically on a group basis in accordance with good management practice.  Tenant’s use of electric energy or water in the Premises shall not at any time exceed the capacity of any of the risers, piping, electrical conductors and other equipment in or serving the Premises.  In order to insure that such capacity is not exceeded and to avert any possible adverse effect upon the Building’s electric system, Tenant shall not, without Landlord’s prior written consent in each instance, connect appliances or heavy duty equipment, other than Ordinary Office Equipment, to the Building’s electric system or make any alteration or addition to the Building’s electric system.  Should Landlord grant its consent in writing, which Landlord may withhold in its sole discretion, all additional risers, piping and electrical conductors or other equipment therefor shall be provided by Landlord and the cost thereof shall be paid by Tenant within thirty (30) days of Landlord’s demand therefor.  As a condition to granting such consent, Landlord may require Tenant to agree to a reasonable increase in Monthly Base Rent to offset the expected cost to Landlord of such additional service, that is, the cost of the additional electric energy to be made available to Tenant based upon the estimated additional capacity of such additional risers, piping and electrical conductors or other equipment.  If Landlord and Tenant cannot agree thereon, such cost shall be determined by an independent electrical engineer, to be selected by Landlord and reasonably approved by Tenant and paid equally by both parties.
E.    Separate Meters.  As part of Tenant’s Work, by no later than the thirtieth (30th) day following the Commencement Date, Tenant shall cause the Premises to be separately metered for lights, plugs and power and the electricity to power the VAV boxes in the Premises, and Tenant shall pay a monthly electricity charge to the applicable electricity provider, based on Tenant’s separately metered use and consumption of such electricity in the Premises. If a direct metering arrangement is not reasonably feasible, then Tenant shall install a so-called submeter for electricity and Tenant shall pay a monthly electricity charge to Landlord, as Additional Rent, based on usage as indicated by such submeter and calculated at Landlord’s actual rate(s) for such electricity (without add-on or mark-up).  If the Premises are separately metered for any other utility, Tenant shall pay a utility charge directly to the utility company (or, if such arrangement is not reasonably feasible, to Landlord, as Additional Rent) based upon Tenant’s actual consumption as measured by the meter.  Landlord also reserves the right (at its expense) to install separate meters for the Premises to register the usage of all or any one of the utilities, and, in such event, Landlord shall pay the cost of installation and Tenant shall pay for the cost of utility usage as metered to the Premises. As to the separate metering of any service or utility, the cost of which was previously included in the Monthly Base Rent and/or Base Year for Operating Expenses or Taxes, there shall be a reasonable and equitable adjustment to Monthly Base Rent and Operating Expenses (for the Base Year and each subsequent year) following such separate metering to reflect that Tenant will thereafter be paying the cost of such service or utility directly.  The term “utility” for purposes hereof may refer to but is not limited to gas, water, sewer, steam, fire protection system, telephone or other communication or alarm service, as well as HVAC, and all taxes or other charges thereon.
F.    Interruptions.  Landlord does not represent or warrant that any of the services referred to above, or any other services which Landlord may supply, will be free from interruption and Tenant acknowledges that any one or more of such services may be suspended by reason of accident, repairs, inspections, alterations or improvements necessary to be made, or by Force Majeure.  Any interruption, reduction or discontinuance of service shall not be deemed an eviction or disturbance of Tenant’s use and possession of the Premises, or any part thereof, nor, except as otherwise set forth herein, render Landlord liable to Tenant for damages, nor relieve Tenant from performance of Tenant’s obligations under this Lease.  Landlord shall however, exercise reasonable diligence to restore any service so interrupted.
Notwithstanding the foregoing, if any essential services to be supplied by Landlord under this Lease are interrupted, and such interruption has resulted from an act or omission of Landlord and as a result of such cessation of service, the Premises, or a material portion thereof, is rendered untenantable (meaning that Tenant is unable to use and gain reasonable access to the Premises, or such material portion thereof, in the normal course of its business) and Tenant provides written notice of such interruption to Landlord, Tenant shall be entitled to an abatement of a proportionate share of the Monthly Base Rent and all Additional Rent and charges, allocable to the affected material portion of the Premises commencing on the third (3rd) consecutive business day of the interruption following the date on which Tenant notifies Landlord of the cessation of such service, and ending on the date such essential services and Tenant’s access and use of the Premises are restored.  If any such interruption continues for fifteen (15) business days after the date of such notice, then for each day thereafter that the interruption continues, Tenant shall be granted a credit of one and one-half (1.5) days’ Monthly Base Rent and Additional Rent, to be applied following the resumption of such services.  If such interruption continues for twenty-five (25) business days after the date of such notice, then for each day thereafter that the interruption continues, Tenant shall be granted a credit of two (2) days’ Monthly Base Rent and Additional Rent, instead of the prior one and one-half (1.5) day rent credit, to be applied following the resumption of such services. 
G.    Additional Utilities Provided by Tenant.  Tenant shall make application in Tenant’s own name for all utilities not provided herein by Landlord and shall: (i) comply with all utility company regulations for such utilities, including requirements for the installation of meters, and (ii) obtain such utilities directly from, and pay for the same when due directly to, the applicable utility companies.  The term “utilities” for purposes hereof shall include but not be limited to telephone and other communication and alarm services, and all taxes or other charges thereon.  Tenant shall install and connect all equipment and lines required to supply such additional utilities to the extent not already available at or serving the Premises, or at Landlord’s option shall repair, alter or replace any such existing items.  Tenant shall maintain, repair and replace all such items, operate the same, and keep the same in good working order and condition.  Tenant shall not install any equipment or fixtures, or use the same, so as to exceed the safe and lawful capacity of any utility equipment or lines serving the same.  The installation, alteration, replacement or connection of any utility equipment and lines shall be subject to the requirements for Alterations of the Premises set forth in Article 5, and Tenant will have the right to use, in common with other tenants and occupants of the Building, common ducts, chases, conduits, and pipes in order to make necessary connections with the Premises.  Tenant shall ensure that all of Tenant’s HVAC equipment that is installed by, on behalf of, or at the request of, Tenant is installed and operated at all times in a manner to prevent roof leaks, damage, or noise due to vibrations or improper installation, maintenance or operation.  Except as specifically provided in this Article 7, Tenant agrees to pay for all utilities and other services utilized by Tenant and additional services furnished to Tenant not uniformly furnished to all tenants of the Office Component at the rate actually paid by Landlord to the utility provider.  
H.    Additional Installations.  If any lights, machines or equipment (including but not limited to computers) used by Tenant in the Premises materially and adversely affect the temperature otherwise maintained by the air conditioning system, or generate substantially more heat in the Premises than would be generated by the building standard lights and Ordinary Office Equipment, and if such adverse effect continues for more than ten (10) business days after notice thereof from Landlord, Landlord shall have the right to install any machinery and equipment which Landlord reasonably deems necessary to restore temperature balance, including but not limited to modifications to the standard air conditioning equipment, and the cost thereof, including the cost of installation and any additional cost of operation and maintenance occasioned thereby, shall be paid by Tenant to Landlord upon demand by Landlord.  Landlord shall not be liable under any circumstances for loss of or injury to property, however occurring, through or in connection with or incidental to failure to furnish any of the foregoing.
I.    Access to Building Common Areas.  Tenant shall have access to the Building Common Areas twenty-four (24) hours per day, seven (7) days per week, three hundred sixty-five (365) days per year.  Upon initial occupancy, Tenant will be entitled to one (1) access card or other access device per employee for use at the Building turnstiles and elevators.  Thereafter, additional access cards or devices may be obtained at the rate of Twenty-Five and 00/100 Dollars ($25.00) per additional card or device, which rate is subject to change from time to time in Landlord’s sole but reasonable discretion.
ARTICLE 8. 
 
INSURANCE
A.    Required Insurance.  Tenant shall, at all times during the Term of this Lease, and at its own cost and expense, maintain insurance policies, with responsible companies licensed to do business in the Commonwealth of Massachusetts and reasonably satisfactory to Landlord, naming Landlord, the Building Manager, Cornerstone Real Estate Advisers LLC, Tenant and any Mortgagee of Landlord, as their respective interests may appear, including: (i) a policy of standard fire, extended coverage and special extended coverage property insurance which shall be primary on the lease improvements referenced in Article 5 and Tenant’s property, including its goods, equipment and inventory, in an amount adequate to cover their insurable replacement cost, including a vandalism and malicious mischief endorsement, and sprinkler leakage coverage; (ii) business interruption insurance, loss of income and extra expense insurance covering the failure of Tenant’s telecommunications equipment and all other perils, failures or interruptions; (iii) commercial general liability insurance on an occurrence basis with limits of liability in an amount not less than Two Million Dollars ($2,000,000) combined single limit for each occurrence, and Three Million Dollars ($3,000,000) in the annual aggregate; and (iv) Worker’s Compensation Coverage as required by law.  The commercial general liability policy shall include contractual liability, provided that contractual liability coverage shall not provide coverage for losses arising from the negligence or willful misconduct of an additional insured.
On or before the Commencement Date, Tenant shall furnish to Landlord and the Building Manager, certificates of insurance evidencing the insurance coverage set forth above, including naming Landlord, Cornerstone Real Estate Advisers LLC and the Building Manager as additional insureds.  Renewal certificates must be furnished to Landlord at least ten (10) days prior to the renewal or replacement of such insurance policies showing the above coverage to be in full force and effect.
The foregoing policy sets forth minimum limits of liability and Tenant’s procurement and maintenance thereof shall in no event limit the liability of Tenant under this Lease.  All such general liability insurance policies carried by Tenant shall be with companies having a rating of not less than A-VIII in Best’s Insurance Guide.  All such policies shall be endorsed to agree that Tenant’s policy is primary and that any insurance covered by Landlord is excess and not contributing with any Tenant insurance requirement hereunder.  Tenant agrees that if Tenant does not take out and maintain such insurance or furnish Landlord with renewals or binders, Landlord may (but shall not be required to) procure said insurance on Tenant’s behalf and charge Tenant the cost thereof, which amount shall be payable by Tenant upon demand with interest from the date such sums are extended.  Tenant agrees that no policy required hereunder will be canceled except upon thirty (30) days prior written notice (except ten (10) days in the case of non-payment of premium) from Tenant or its insurance agent or consultant.  Tenant shall comply with all reasonable and generally applicable rules and directives of any insurance board, company or agency determining rates of hazard coverage for the Premises, including but not limited to the installation of any equipment and/or the correction of any condition necessary to prevent any increase in such rates such as may result from a violation by Tenant.
B.    Landlord’s Insurance.  During the Term of this Lease, Landlord shall maintain ”Special Form” property and commercial general liability insurance covering the Building.  The Special Form property insurance policy shall cover all structures and improvements for full replacement value, with replacement cost endorsement, above foundation walls. Landlord’s Commercial General Liability Insurance shall be written on an occurrence basis with minimum limits of liability in an amount of not less than $5,000,000.00, combined single limit, for bodily injury or death including personal injury, and with respect to damage to the property of others, including legal liability arising out of any one occurrence, which insurance shall contain contractual liability insurance coverage. The commercial general liability insurance shall insure against claims for bodily injury and property damage occurring in or about the Building.  Such insurance may be included in blanket policies carried by Landlord so long as such blanket policies do not reduce the amount of insurance available to pay any claim with respect to the Building.
C.    Waiver of Subrogation.  Landlord and Tenant each agree that neither Landlord nor Tenant will have any claim against the other for any loss, damage or injury which is covered by insurance carried by either party and for which recovery from such insurer is made, notwithstanding the negligence of either party in causing the loss, and each agree to have their respective insurers issuing the insurance described in this Article 8 waive any rights of subrogation that such companies may have against the other party.  Each party agrees to use commercially reasonable efforts to obtain such an agreement from its insurer if the policy does not expressly permit a waiver of subrogation.
D.    Waiver of Claims.  Except for claims arising from Landlord’s willful misconduct or negligence that are not covered by Tenant’s insurance required hereunder, Tenant waives all claims against Landlord for injury or death to persons, damage to property or to any other interest of Tenant sustained by Tenant or any party claiming, through Tenant resulting from: (i) any occurrence in or upon the Premises; (ii) leaking of roofs, bursting, stoppage or leaking of water, gas, sewer or steam pipes or equipment, including sprinklers; (iii) wind, rain, snow, ice, flooding, freezing, fire, explosion, earthquake, excessive heat or cold, or other casualty; (iv) the Building, Premises, or the operating and mechanical systems or equipment of the Building, being defective, or failing; and (v) vandalism, malicious mischief, theft or other acts or omissions of any other parties including, without limitation, other tenants, contractors and invitees at the Building.  In no event will Landlord or Tenant be responsible for any consequential damages incurred by the other party, including but not limited to, lost profits or interruption of business as a result of any alleged default hereunder; provided, however, that no remedies or damages expressly provided in this Lease shall be considered indirect or consequential, and that the provisions of this Article 8.D. shall not apply to Articles 15 and 27 of this Lease.
ARTICLE 9. 
 
INDEMNIFICATION
A.    Tenant Indemnity of Landlord.  Except to the extent resulting from the willful misconduct or negligence of Landlord or its agents, employees or contractors, and subject to Article 8.C., Tenant shall defend, indemnify and hold harmless Landlord and its agents, successors and assigns, including the Building Manager, from and against any and all injury, loss, costs, expenses, liabilities, claims or damage (including attorneys’ fees and disbursements) to any person or property (i) arising from, related to, or in connection with any use or occupancy of the Premises by Tenant, or (ii) arising from, related to, or in connection with any negligent or willful and wrongful act or omission (including, without limitation, construction and repair of the Premises arising out of any Alterations) of Tenant, its agents, contractors, employees, customers, and invitees, or (iii) or arising from any uncured default by Tenant under this Lease.  This indemnification shall survive the expiration or termination of the Lease Term.
B.    Landlord Indemnity of Tenant.  Landlord shall defend, indemnify and hold Tenant harmless from and against all claims, causes of action, liabilities, losses, costs and expenses arising from or in connection with (i) any injury or other damage to any person or property resulting from any act or omission of Landlord, or (ii) any uncured default by Landlord under this Lease.  This indemnification shall survive the expiration or termination of the Lease Term.
C.    Indemnity Limitations.  The indemnity obligations set forth in Sections A. and B. above shall not apply (i) to any costs or expenses not reasonably incurred by the indemnitee, or (ii) to any claims, causes of action, liabilities, losses, costs and expenses resulting from a default by the indemnitee hereunder.
D.    Indemnitees; Acceptable Attorneys.  Whenever, in this Article 9 and throughout this Lease, Landlord or Tenant is required to defend, indemnify and hold the other harmless, such obligations shall extend to the successors, assigns, officers, partners, members, managers, directors, employees and other agents of the indemnitee.  In any instance where this Lease requires either party to defend the other, such defense shall involve an attorney or attorneys reasonably acceptable to the indemnitee.
E.    Limitation on Liability.  Landlord shall not be liable to Tenant for any damage by or from any act or negligence of any tenant or other occupant of the Building, or by any owner or occupants (other than Landlord or its affiliated entities) of adjoining or contiguous property.  Landlord shall not be liable for any injury or damage to persons or property resulting in whole or in part from the criminal activities or willful misconduct of others.  Subject to Article 8.C. above, Tenant agrees to pay for all damage to the Building, as well as all damage to persons or property of other tenants or occupants thereof, caused by the negligence, fraud or willful misconduct of Tenant or any of its agents, contractors, employees, customers (while located in the Premises) and invitees (while located in the Premises).  Nothing contained herein shall be construed to relieve Landlord from liability for any personal injury resulting from its negligence, fraud or willful misconduct and that of its agents, employees or contractors.
F.    Surveillance.  Tenant acknowledges that Landlord’s election to provide mechanical surveillance or to post security personnel in the Building is subject to Landlord’s sole discretion.  Except to the extent resulting from the willful misconduct or negligence of Landlord or its agents, employees or contractors, and then subject to Article 8.C. above, Landlord shall have no liability in connection with the decision whether or not to provide such services and Tenant hereby waives all claims based thereon. Landlord shall not be liable for losses due to theft, vandalism, or like causes.  
ARTICLE 10. 
 
CASUALTY DAMAGE
Tenant shall promptly notify Landlord or the Building Manager of any fire or other casualty to the Premises, or, to the extent it knows of damage, to the Building.  In the event the Premises or any substantial part of the Building is wholly or partially damaged or destroyed by fire or other casualty which is covered by the insurance that Landlord is required to carry hereunder, Landlord will proceed to restore the same to substantially the same condition existing immediately prior to such damage or destruction unless Landlord notifies Tenant (the “Casualty Notice”) that (i) such damage or destruction is incapable of repair or restoration within three hundred sixty-five (365) days from commencement thereof as reasonably determined by Landlord’s architect; or (ii) the insurance proceeds recovered by reason of the damage or destruction (together with the amount of any deductible) are, in Landlord’s commercially reasonable judgment, inadequate to complete the restoration of the Building; or (iii) Landlord elects not to repair or restore the Building; in any of which events Landlord or Tenant may, by written notice given to the other party within twenty (20) days of Tenant’s receipt of the Casualty Notice, declare this Lease terminated as of the happening of such damage or destruction. Any Casualty Notice must be delivered within forty-five (45) days after the date of such damage.  To the extent after fire or other casualty that Tenant shall be deprived of the use and occupancy of the Premises or any portion thereof as a result of any such damage, destruction or the repair thereof, providing Tenant did not intentionally cause the fire or other casualty, then Tenant shall be relieved of the same ratable portion of the Monthly Base Rent and all additional rent due under this Lease as the amount of damaged or useless space in the Premises bears to the rentable square footage of the Premises until such time as the Premises may be restored.  Landlord shall reasonably determine the amount of damaged or useless space and the square footage of the Premises referenced in the prior sentence and whether or not its insurance covers the payment of Rent.  Tenant may elect to terminate this Lease: (a) if the Casualty Notice states that it will take greater than three hundred sixty-five (365) days to complete the restoration or repair from the time that such restoration or repair commences, provided that Tenant gives such notice within thirty (30) days after delivery of the Casualty Notice; or (b) if the restoration or repair is not completed within three hundred sixty-five (365) days (or such longer period as is specified in the Casualty Notice, plus an additional contingency period equal to twenty percent (20%) of such scheduled period) of the casualty, plus an additional period of up to sixty (60) days on account of Force Majeure; provided however, that if such restoration or repair is completed within thirty (30) days following receipt of Tenant’s notice of termination, then such notice of termination shall be deemed null and void and of no further force or effect.
ARTICLE 11. 
 
CONDEMNATION
In the event of a condemnation or taking of the entire Premises by a public or quasi-public authority, this Lease shall terminate as of the date title vests in the public or quasi-public authority. In the event of (i) a taking or condemnation of fifteen percent (15%) or more (but less than the whole) of the Building and without regard to whether the Premises are part of such taking or condemnation; (ii) a taking or condemnation which results in Landlord electing not to restore the Building; or (iii) a taking or condemnation which results in Landlord electing to change the use of the land upon which the Building is located, Landlord may elect to terminate this Lease by giving notice to Tenant within sixty (60) days of Landlord receiving notice of such condemnation.  In the event of a partial taking as described in this Article 11, or a sale, transfer or conveyance in lieu thereof, which does not result in the termination of this Lease, Rent shall be apportioned according to the ratio that the part of the Premises remaining usable by Tenant bears to the total area of the Premises.  All compensation awarded for any condemnation shall be the property of Landlord, whether such damages shall be awarded as a compensation for diminution in the value of the leasehold or to the fee of the Premises, and Tenant hereby assigns to Landlord all of Tenant’s right, title and interest in and to any and all such compensation; provided, however that in the event this Lease is terminated, Tenant shall be entitled to make a separate claim for the taking of Tenant’s personal property (including fixtures paid for by Tenant), and for costs of moving, provided that any such award to Tenant is payable separately and does not diminish the award available to Landlord or any Lender of Landlord.  Any additional portion of such award shall belong to Landlord.  Tenant hereby waives any and all rights, imposed by law, statute, ordinance, governmental regulation or requirement of the United States, the Commonwealth of Massachusetts or any local government authority or agency or any political subdivision thereof, now or hereafter in effect, it might otherwise have to petition a court to terminate the Lease. In the event that any portion of the Premises shall be the subject to condemnation or a taking and Tenant determines that the remainder, even after restoration, would not be reasonably suitable for Tenant’s continued use, then this Lease may be terminated at the election of Tenant, which election shall be made by giving of notice by Tenant to Landlord within thirty (30) days after the date of the condemnation or taking.
ARTICLE 12. 
 
REPAIR AND MAINTENANCE
A.    Tenant’s Obligations.  Tenant shall keep the Premises in good working order, repair (and in compliance with all Laws now or hereafter adopted) and condition (which condition shall be neat, clean and sanitary) and shall make all necessary non-structural repairs thereto and any repairs to non-Building standard mechanical, HVAC, electrical and plumbing systems or components located in and exclusively serving the Premises.  Tenant’s obligations hereunder shall include, but not be limited to, Tenant’s trade fixtures and equipment, security systems, signs, interior decorations, floor-coverings, wall-coverings, entry and interior doors, interior glass, light fixtures and bulbs, keys and locks, and Alterations to the Premises whether installed by Tenant or Landlord.  Landlord may make any repairs which are not promptly made by Tenant after Tenant’s receipt of written notice and the reasonable opportunity of Tenant to make said repair within five thirty (30) days from receipt of said written notice, and charge Tenant for the cost thereof, which cost shall be paid by Tenant within thirty (30) days from invoice therefor from Landlord.  Tenant waives all rights to make repairs at the expense of Landlord, or to deduct the cost thereof from Rent.
B.    Landlord’s Obligations.  Landlord shall maintain, in a condition similar to other first-class office buildings in the Boston market and in material compliance with all applicable Laws (other than those Laws applicable to a tenant’s unique use and occupancy of its premises or to any alterations or other work performed by, on behalf of, or at the request of, such tenant), (i) the foundations, roof, perimeter walls and exterior windows and all structural aspects of the Building, and (ii) all nonstructural aspects of the Building which relate to the Building Common Areas or to more than one tenant’s premises, or which no tenant of the Building is required to maintain and repair, including all systems and facilities necessary for the operation of the Building and the provision of services and utilities as required herein (except to the extent that any of the foregoing items are installed by or on behalf of, or are the property of, Tenant).  Landlord shall also make all necessary structural repairs to the Building and any necessary repairs to the Building standard mechanical, HVAC, electrical, and plumbing systems in or servicing the Premises (the cost of which shall be included in Operating Expenses to the extent permitted under Article 4), excluding repairs required to be made by Tenant pursuant to this Article 12.  Landlord shall have no responsibility to make any repairs unless and until Landlord receives written notice of the need for such repair or otherwise becomes aware.  Landlord shall not be liable for damages arising from any failure to make repairs or to perform any maintenance unless such failure shall persist for an unreasonable period of time after written notice of the need for such repairs or maintenance is received by Landlord from Tenant or after Landlord otherwise becomes aware.  Landlord shall make every reasonable effort to perform all such repairs or maintenance in such a manner (in its judgment) so as to cause minimum interference with Tenant and the Premises but Landlord shall not be liable to Tenant (except as may otherwise be expressly provided in this Lease) for any interruption or loss of business pertaining to such activities.  Landlord shall have the right to require (subject to Article 8.C.) that any damage caused by the willful misconduct of Tenant or any of Tenant’s agents, contractors or employees, be paid for and performed by the Tenant (without limiting Landlord’s other remedies herein).
C.    General Obligations.  Alterations to the Premises required from time to time to comply with applicable Laws, requirements of any board of property insurance underwriters or similar entity, or reasonable requirements of Landlord’s or Tenant’s insurers shall be made by the party to this Lease responsible for maintaining and repairing the applicable aspect of the Premises hereunder, provided that Landlord shall be responsible for any such alteration that is not required solely on account of Tenant’s particular use (other than general business offices) of the Premises or Alterations to the Premises.  Landlord warrants to Tenant that, as of the Commencement Date, all aspects of the Premises comprising the Base Building Condition shall comply with all applicable Laws, with the requirements of Landlord’s insurers, and with the requirements of all boards of property insurance underwriters and similar entities.
D.    Signs and Obstructions.  Tenant shall not obstruct or permit the obstruction of lights, halls, Building Common Areas, roofs, parapets, stairways or entrances to the Building or the Premises and will not affix, paint, erect or inscribe any sign, projection, awning, signal or advertisement of any kind to any part of the Building outside of the Premises, including the inside or outside of the windows or doors, or within the Premises if same can be seen from outside of the Premises, without the written consent of Landlord.  If such work is done by Tenant through any person, firm or corporation not approved by Landlord, or without the express written consent of Landlord, Landlord shall have the right to remove such signs, projections, awnings, signals or advertisements without being liable to the Tenant by reason thereof and to charge the cost of such removal to Tenant as Additional Rent, payable within ten (10) days of Landlord’s demand therefor. Tenant shall be entitled to Building-standard lobby directory signage, in common with other tenants of the Building, at no additional cost.
E.    Outside Services.  Tenant shall not permit, except by Landlord or a person or company reasonably satisfactory to and approved by Landlord: (i) the servicing of Tenant’s supplemental heating, ventilating and air conditioning equipment in the Premises and (ii) window cleaning, janitorial services or similar work in or about the Premises.
F.    Condition of Premises.  Except as otherwise provided herein to the contrary (including without limitation Landlord’s ongoing repair and maintenance obligations), Tenant hereby agrees that the Premises shall be taken “as is,” “with all faults,” and “without any representations or warranties,” and Tenant hereby acknowledges and agrees that it has investigated and inspected the condition of the Premises and the suitability of same for Tenant’s purposes, and except for matters or conditions that could not reasonably be detected by a reasonably careful inspection, Tenant does hereby waive and disclaim any objection to, cause of action based upon, or claim that its obligations hereunder should be reduced or limited because of the condition of the Premises or the Building or the suitability of same for Tenant’s purposes.  Tenant acknowledges that neither Landlord nor any agent nor any employee of Landlord has made any representation or warranty with respect to the suitability of the Premises or the Building for the conduct of Tenant’s business and Tenant expressly represents and warrants that Tenant has relied solely on its own investigation and inspection of the Premises and the Building in its decision to enter into this Lease and let the Premises in an “As Is” condition.  The Premises shall be initially improved by Tenant as provided in, and subject to, the terms and conditions of Exhibit B attached hereto and made a part hereof.  The Tenant Improvements (as defined in Exhibit B), together with any subsequent Alterations during the Term of this Lease, may be collectively referred to herein as the “Premises Improvements.”  The taking of possession of the Premises by Tenant shall conclusively establish that the Premises and the Building were at such time in satisfactory condition.  
Landlord reserves the right from time to time, but subject to payment by and/or reimbursement from Tenant as otherwise provided herein: (i) to install, use, maintain, repair, replace and relocate for service to the Premises and/or other parts of the Building pipes, ducts, conduits, wires, appurtenant fixtures, and mechanical systems, wherever located in the Premises or the Building, (ii) to alter, close or relocate any facility in the Premises or the Building Common Areas or otherwise conduct any of the above activities for the purpose of complying with a general plan for fire/life safety for the Building or otherwise and (iii) to comply with any Law with respect thereto or the regulation thereof not currently in effect. Landlord shall attempt to perform any such work with the least inconvenience to Tenant as possible, but, except as otherwise expressly provided herein, so long as the activities by Landlord set forth in (i) and (ii) do not unreasonably interfere with Tenant’s operations in the Premises,  Tenant shall not be permitted to withhold or reduce Rent or other charges due hereunder as a result of same or otherwise make claim against Landlord for interruption or interference with Tenant’s business and/or operations.
ARTICLE 13. 
 
INSPECTION OF PREMISES
Tenant shall permit the Landlord, the Building Manager and its authorized representatives to enter the Premises upon at least twenty-four (24) hours’ advance notice to show the Premises during Normal Business Hours of the Building (provided, however, that Landlord’s right to show the Premises to prospective tenants shall be limited to the last twelve (12) months of the Term) and at other reasonable times to inspect the Premises, to clean the Premises, to serve or post notices as provided by law or which Landlord reasonably deems necessary for the protection of Landlord or Landlord’s property, and to make such repairs, improvements, alterations or additions in the Premises or in the Building of which they are a part as Landlord may deem necessary or appropriate and at any time in the event of an emergency.   If Tenant shall not be personally present to open and permit an entry into the Premises at any time when such an entry is necessary or permitted hereunder, Landlord may enter by means of a master key or may enter forcibly, only in the case of an emergency, without liability to Tenant and without affecting this Lease. Landlord shall (except in cases of emergency) use commercially reasonable efforts to avoid unnecessary interruption of Tenant’s use of the Premises in any entry authorized hereby.  Except in cases of emergency, Landlord will cooperate with Tenant to schedule such entry in a manner so as to minimize interference with Tenant’s operations, and, if Tenant requests and pays for any incremental premium cost actually incurred by Landlord as a result of such request, Landlord will enter after hours.
ARTICLE 14. 
 
SURRENDER OF PREMISES
Upon the expiration of the Term, or sooner termination of the Lease, Tenant shall quit and surrender to Landlord the Premises, broom clean, in good order and condition, normal wear and tear and damage by fire and other casualty which are Landlord’s obligation excepted.  All Premises Improvements and other fixtures, such as light fixtures and HVAC equipment, wall coverings, carpeting and drapes, in or serving the Premises, whether installed by Tenant or Landlord, shall be Landlord’s property and shall remain, all without compensation, allowance or credit to Tenant; provided that Tenant shall, at its expense, remove any Alterations made by tenant after completion of the Tenant Improvements  and that were required to be so removed by Landlord in any notice given to Tenant at the time of approval of such Alterations in accordance with Article 5.C. above and/or Exhibit B attached hereto, and repair any damages to the Premises caused by such removal, all at Tenant’s sole cost and expense.  Unless Landlord has otherwise directed Tenant to do so in writing under Exhibit B attached hereto at the time of Landlord’s approval, Tenant shall not be required to remove any of the Tenant Improvements.  Upon the expiration or earlier termination of this Lease, Tenant shall remove from the Premises all of Tenant’s furniture, trade fixtures, furnishings, equipment and other personal property and repair any damage caused by such removal, at Tenant’s sole cost and expense.  Any property not removed shall be deemed to have been abandoned by Tenant and may be retained or disposed of by Landlord at Tenant’s expense free of any and all claims of Tenant, as Landlord shall desire.  All property not removed from the Premises by Tenant may be handled or stored by Landlord at Tenant’s expense and Landlord shall not be liable for the value, preservation or safekeeping thereof.  At Landlord’s option all or part of such property may be conclusively deemed to have been conveyed by Tenant to Landlord as if by bill of sale without payment by Landlord.  Tenant hereby waives, to the maximum extent allowable, the benefit of all Laws now or hereafter in force in the Commonwealth of Massachusetts or elsewhere exempting property from liability for rent or for debt.
ARTICLE 15. 
 
HOLDING OVER
Should Tenant, without Landlord’s written consent, hold over after termination of this Lease, Tenant shall become a tenant at sufferance and any such holding over shall not constitute an extension of this Lease.  Tenant shall pay Landlord, monthly and in advance, one hundred fifty percent (150%) of the annual Rent that was payable immediately preceding the Expiration Date (without regard to any abatement or reduction of Rent or other alternative rent actually in effect at such time), prorated on a per diem basis, for each day Tenant shall retain possession of the Premises or any part thereof after expiration or earlier termination of this Lease, which percentage shall increase to two hundred percent (200%) after the first (1st) thirty (30) days of such holdover, together with all damages sustained by Landlord on account thereof and all other payments required to be made by Tenant hereunder.  The foregoing provisions shall not serve as permission for Tenant to hold-over, nor serve to extend the Term (although Tenant shall remain bound to comply with all provisions of this Lease until Tenant vacates the Premises) and Landlord shall have the right at any time thereafter to enter and possess the Premises and remove all property and persons therefrom or to require Tenant to surrender possession of the Premises as provided in this Lease upon the expiration or earlier termination of the Term.  If Tenant fails to surrender the Premises upon the expiration or termination of this Lease, Tenant agrees to indemnify, defend and hold harmless Landlord from all costs, loss, expense or liability, including without limitation, claims made by any succeeding tenant and real estate brokers’ claims and attorneys’ fees, provided that Tenant shall not be required to indemnify Landlord from losses or damages suffered as a result of or in connection with the loss of (or delay in occupancy or rent payment by, or other increased financial exposure or liability to) a replacement or successor tenant until the sooner of (i) thirty (30) days beyond the expiration or earlier termination of this Lease, or (ii) ten (10) business days after Landlord has given Tenant written notice of such replacement or successor tenant.  No acceptance by Landlord of any Rent during or for any period following the expiration or termination of the Lease shall operate or be construed as an extension or renewal of the Lease.  Should Tenant remain in the Premises on a month-to-month basis with Landlord’s prior and express written approval, such month-to-month tenancy may be cancelled by either party with thirty (30) days’ prior written notice or such lesser time period as may be permitted by Law.
ARTICLE 16. 
 
SUBLETTING AND ASSIGNMENT
A.    Landlord’s Consent.  Except as provided herein, Tenant shall not assign its interests hereunder, sublease all or any portion of the Premises (for purposes of this Lease, a license shall be deemed to be a sublease), or list the Premises or any part thereof as available for assignment or sublease with any broker or agent or otherwise advertise, post, communicate or solicit prospective assignees or subtenants through any direct or indirect means, or allow any other person to use or occupy any portion of the Premises, without the prior written consent of Landlord, which shall not be unreasonably withheld, delayed or conditioned, except that Landlord shall not, under any circumstances, be obligated to consent to any assignment or subletting by Tenant (i) to any other tenant of the Building, so long as Landlord then has or will (as of the effective date of Tenant’s proposed assignment or subletting) have additional comparable space available in the Building to lease to such other tenant, (ii) by operation of Law (subject to Article 16.B. below) or (iii) to any person who fails to meet any of the other reasonable criteria of Landlord that Tenant was required to meet prior to the execution of this Lease.  Without limiting the generality of the foregoing, it shall be reasonable for Landlord to deny consent if:
(1)    The financial strength of the proposed assignee, both in terms of net worth and in terms of reasonably anticipated cash flow over the Lease Term, is not reasonably acceptable to Landlord, taking into account the fact that Tenant would still be liable under the terms of this Lease (unless Tenant is released by Landlord as provided herein).
(2)    The proposed assignee or subtenant will burden the Premises and/or Building Common Areas to an extent substantially in excess of that of typical office tenants of the Building, whether through disproportionate demand for landlord services or utilities, disproportionate bearing weights on floor areas, disproportionate parking requirements, deterioration of floors or other elements of the Building, or otherwise.
(3)    The proposed assignee or subtenant intends to make substantial alterations to the Premises which would, in Landlord’s reasonable judgment, result in a material net decrease in the value of the Premises as improved.
(4)    The proposed assignee’s or subtenant’s use of the Premises will not, in Landlord’s commercially reasonable judgment, be compatible with the uses of the other tenants in the Building or will be appropriate for a Class A office building.
(5)    The use to be made of the Premises by the proposed assignee or subtenant is for other than general or professional business offices and is (A) not generally consistent with the character and nature of all other tenancies in the Office Component, or (B) a use which conflicts with any so-called “exclusive” then in favor of, or for any use which is the same as that stated in any percentage rent lease to, another tenant of the Building, or (C) a use which would be prohibited by any other portion of this Lease (including, but not limited to, any rules and regulations then in effect).
(6)    The proposed assignee or subtenant is either a governmental agency or instrumentality thereof.
(7)    Either the proposed assignee or subtenant or any person or entity which controls, is controlled by or is under common control with the proposed assignee or subtenant (A) occupies space in the Building at the time of the request for consent, and Landlord then has or will (as of the effective date of Tenant’s proposed assignment or subletting) have additional comparable space available in the Building to lease to such proposed assignee or subtenant, or (B) is negotiating with Landlord or has negotiated with Landlord during the six (6) month period immediately preceding the date of the proposed transfer, to lease space in the Building.  For purposes hereof, “control” requires both (a) owning (directly or indirectly) more than fifty percent (50%) of the stock or other equity interests of another person and (b) possessing, directly or indirectly, the power to direct or cause the direction of the management and policies of such person.
(8)    The proposed assignee or subtenant (A) has an anticipated use of the Premises involving the generation, storage, use, treatment, or disposal of Hazardous Material in a way or to an extent that is greater than general business office use; or (B) has been required by any prior landlord, lender, or governmental authority to take remedial action in connection with Hazardous Material contaminating a property if the contamination resulted from such transferee’s actions or use of the property in question.
With respect to any proposed assignment or subleasing requiring Landlord’s consent, Tenant shall submit to Landlord in writing, at least thirty (30) days prior to the effective date of the assignment or sublease, (a) a notice of application to assign or sublease, setting forth the proposed effective date, which shall be not less than thirty (30) or more than one hundred  twenty (120) days after the delivery of such notice; (b) the name of the proposed assignee or subtenant; (c) the nature of the proposed assignee’s or subtenant’s business to be carried on in the Premises; (d) the terms of the proposed sublease or assignment; and (e) a current financial statement of the proposed assignee or subtenant.  Tenant shall not submit any such application to Landlord until Tenant has received a bona fide offer from the proposed assignee or subtenant, and Tenant shall furnish Landlord, in addition to the foregoing, with all other information reasonably required by Landlord with respect to such assignment or sublease, assignee or subtenant.  Unless the stock in Tenant is publicly traded on a regulated securities exchange, any transfer (or sequence of transfers resulting, in the aggregate, in the transfer) of fifty percent (50%) or more of the beneficial ownership of Tenant shall constitute an assignment for purposes of this Article 16.
B.    Transfers Not Requiring Consent.  Notwithstanding the foregoing, Landlord’s consent shall not be required with respect to any assignment or sublease to (1) an entity which controls Tenant or which controls the entity which controls Tenant (in either case, a “Parent”), or (2) an entity which is controlled by Tenant or a Parent, or (3) an entity which is controlled by an entity which is controlled by Tenant or a Parent, or (4) any entity resulting from a merger or consolidation involving Tenant, or (5) any entity which acquires all or substantially all of Tenant’s assets, including, without limitation, Tenant’s leasehold interest in and to this Lease (each, a “Permitted Transfer”). For purposes hereof, “control” requires both (a) owning (directly or indirectly) more than fifty percent (50%) of the stock or other equity interests of another person and (b) possessing, directly or indirectly, the power to direct or cause the direction of the management and policies of such person.  With respect to any Permitted Transfer, the following provisions shall apply:

(a)    Tenant shall give Landlord written notice of the assignment or subletting no less than thirty (30) days prior to the effective date thereof (unless restricted from doing so by legal or contractual requirement, in which case such notice shall be given promptly after such transfer),, which notice shall set forth the identity of the proposed assignee or subtenant, the reason(s) why Landlord’s consent is not required, and the nature of the proposed assignee’s or subtenant’s business to be carried on in the Premises.
(b)    Except as aforesaid, Tenant shall furnish Landlord (i) no less than thirty (30) days prior to the effective date of the assignment or subletting, with a current financial statement of the proposed assignee or subtenant reasonably acceptable to Landlord, and (ii) within three (3) days following Landlord’s demand, with all other information reasonably requested by Landlord with respect to such assignee or subtenant.
Any assignment or subletting to which Landlord’s consent is not required and with respect to which the provisions of this Article 16.B. are not complied with shall, at Landlord’s option, be void.
C.    Procedure.  Except for Permitted Transfers, Landlord shall notify Tenant within thirty (30) days from the submission of the aforesaid information as to Landlord’s choice, at Landlord’s sole discretion, of the following options:
(1)    That Landlord consents to a subleasing of the Premises or assignment of the Lease to such replacement tenant provided that Tenant shall remain fully liable for all of its obligations and liabilities under this Lease; or 
(2)    That upon such replacement tenant’s entering into a mutually satisfactory new lease for the Premises with Landlord, then Tenant shall be released from all further obligations and liabilities under this Lease (excepting only any unpaid rentals or any unperformed covenants then past due under this Lease or any guarantee by Tenant of replacement tenant’s obligations); or
(3)    That Landlord reasonably declines to consent to such sublease or assignment due to insufficient or unsatisfactory documentation furnished to Landlord to establish Tenant’s reputation, financial strength and proposed use of and operations upon Premises; or
(4)    That Landlord elects to cancel the Lease and recapture the Premises (in the case of an assignment) or (as to any proposed sublease that either covers all or substantially all of the Premises or covers any portion of the Premises for substantially all of the remaining Term) that Landlord elects to cancel the Lease as to the portion thereof that Tenant had wished to sublease, provided, however, that in either such case, Tenant shall have the right to withdraw its request for Landlord consent to the proposed assignment or sublease in question upon written notice to Landlord delivered within five (5) business days following Tenant’s receipt of Landlord’s recapture notice, in which case Landlord’s recapture notice shall be void.  In either such event, and provided that Tenant has not withdrawn its request for consent as provided above, Tenant shall surrender possession of the Premises, or the portion thereof which is the subject of Tenant’s request on the date set forth in a notice from Landlord in accordance with the provisions of this Lease relating to the surrender of the Premises.  If this Lease shall be canceled as to a portion of the Premises only, the Rent payable by Tenant hereunder shall be abated proportionately according to the ratio that the area of the portion of the Premises surrendered (as computed by Landlord) bears to the area of the Premises immediately prior to such surrender.  If Landlord shall cancel this Lease, Landlord may re-let the Premises, or the applicable portion of the Premises, to any other party (including, without limitation, the proposed assignee or subtenant of Tenant), without any liability to Tenant.
D.    Net Revenues.
(1)    Sublease Revenues.  Except in the case of a Permitted Transfer, in the event that Tenant subleases all or any portion of the Premises and the total of all amounts payable to Tenant for any month under any such sublease exceeds the total of all amounts payable to Landlord hereunder for such month for the same space, Tenant shall pay to Landlord one-half (1⁄2) of the “Net Revenue,” which shall mean such excess actually received by Tenant, but only after Tenant has fully recovered from such excess payments all of Tenant’s costs and expenses incurred in connection with such sublease, including without limitation brokerage commissions and legal fees and costs, advertising or marketing costs and the costs of any improvements or alterations (or allowances for improvements or alterations), and any such Net Revenue actually received by Tenant for any month shall be paid to Landlord within five (5) business days thereafter.
(2)    Assignment Revenues.  Except in the case of a Permitted Transfer, in the event that Tenant assigns this Lease with respect to all or any portion of the Premises (the “assigned premises”), Tenant shall pay to Landlord the Net Revenue actually received by Tenant in connection with such assignment.
E.    Continuing Liability; Voidable Transfers.  No assignment of this Lease (other than an assignment to Landlord resulting from Landlord’s right of recapture), and no subletting of all or any portion of the Premises, shall release Tenant or any guarantor with respect to any post-transfer obligations, unless Landlord agrees otherwise in writing in its absolute discretion and any such assignment or sublease shall, at Landlord’s option, be void in the event that Tenant and each such guarantor, if any, does not expressly acknowledge and affirm its continuing liability in form and substance reasonably satisfactory to Landlord.  The continuing liability of the assigning Tenant shall be primary, and Landlord shall be entitled to exercise its rights and remedies against any such assignor with respect to any Tenant Default without exhausting its rights and remedies against any successor of such assignor.  In the event that it is ever held, notwithstanding the contrary intention of the parties hereto, that any such assignor’s continuing liability is that of a guarantor (rather than primary), Tenant hereby waives any and all suretyship rights and defenses to which it would otherwise be entitled in connection with such continuing liability.  Notwithstanding the foregoing, in the event that, following any assignment (other than an assignment described in Article 16.B. above), Landlord and such assignee modify this Lease in such a way as to increase Tenant’s total obligations hereunder, neither the assigning Tenant nor any guarantor whose guaranty pre-dated such assignment shall be liable for the incremental portion of Tenant’s obligations corresponding to such increase.  The acceptance of any assignment by an assignee shall automatically constitute the assumption by such assignee of all obligations of Tenant with respect to the assigned premises that accrue following the assignment; provided, however, that any assignment of this Lease shall, at Landlord’s option, be void in the event that the assignee does not expressly acknowledge and affirm the effectiveness of the foregoing assumption in form and substance reasonably satisfactory to Landlord.  Any assignment or subletting by Tenant to which Landlord’s consent is required but not obtained shall, at Landlord’s option, be void.
F.    Other Provisions Applicable to Transfers.  No assignment or subletting shall be deemed to modify any provision of this Lease, with respect to permitted or restricted uses of the Premises or otherwise, unless Landlord then agrees otherwise in writing in its absolute discretion.  Tenant shall promptly furnish Landlord with a copy of each executed assignment or sublease, and with copies of any supplements or modifications thereto which may be executed from time to time.
G.     [INTENTIONALLY OMITTED]
H.    Transfers by Subtenants.  The provisions of this Article 16 shall also apply to assignments and subleases by subtenants, sub-subtenants and so on.
I.    Assignment of Options.  Without limiting the generality of any provision of this Lease which states that any option or other right of Tenant is personal to the original Tenant hereunder or may only be assigned under certain conditions, no option or similar right of Tenant hereunder, including without limitation any option to extend or renew, option to expand, first offer or first refusal right, or first right to lease, may be assigned (except in event of a transfer contemplated by Article 16.B. herein), and any attempt to assign such right shall be null and void.
J.    Encumbrance.  Tenant shall not assign its interests hereunder as security for any obligation without Landlord’s prior written consent, which may be withheld in Landlord’s absolute discretion, and any such assignment without such consent shall, at Landlord’s option, be void.
K.    Transfer Fee.  Whether or not Landlord consents to any such transfer, and except with respect to any assignment or sublease described in Article 16.B above, Tenant shall pay to Landlord Landlord’s reasonable attorneys’ fees incurred in connection with the proposed assignment or sublease.
L.    Form of Sublease Consent.  Any consent to a sublease by Landlord in accordance with the provisions of this Article 16 shall be provided in the form attached hereto as Exhibit C.
ARTICLE 17. 
 
SUBORDINATION, NON-DISTURBANCE, ATTORNMENT AND
MORTGAGEE PROTECTION; LEASE SUBJECT TO PROJECT DOCUMENTS

A.    Subordination, Non-Disturbance, Attornment and Mortgagee Protection.  This Lease is subject and subordinate to (i) the priority of the lien of any Mortgage now or hereafter placed upon the Building and (ii) all other encumbrances and matters now or hereafter of public record applicable to the Building, including without limitation, any reciprocal easement or operating agreements, ground or underlying leases, covenants, conditions and restrictions, and Tenant shall not act or permit the Premises to be operated in violation thereof (so long as the same do not impair or restrict the use of the Premises for the Permitted Uses contemplated by this Lease)..  Landlord shall have the right to cause this Lease to be and become and remain subject and subordinate to any and all ground or underlying leases or Mortgages which may hereafter be executed covering the Premises, the Building or the property or any renewals, modifications, consolidations, replacements or extensions thereof, for the full amount of all advances made or to be made thereunder and without regard to the time or character of such advances, together with interest thereon and subject to all the terms and provisions thereof; provided, however, that as a condition to any such subordination with respect to the Mortgage encumbering the Building as of the date of this Lease, Landlord shall obtain from any Lender or other party in question a written undertaking in favor of Tenant to the effect that such Lender or other party will not disturb Tenant’s right of possession or other rights under this Lease if no event of default then exists and otherwise substantially the form attached hereto as Exhibit G, which SNDA Tenant agrees, within ten (10) business days after Tenant’s receipt of Landlord’s written request therefor, to execute, acknowledge and deliver upon request.  With respect to any future Mortgage, Landlord agrees to use commercially reasonable efforts to obtain an SNDA in favor of Tenant, provided, however, that same shall not be a condition to the effectiveness of the subordination of this Lease to such future Mortgage.  To the extent not expressly prohibited by Law, Tenant waives the provisions of any Law now or hereafter adopted which may give or purport to give Tenant any right or election to terminate or otherwise adversely affect this Lease or Tenant’s obligations hereunder if such foreclosure or power of sale proceedings are initiated, prosecuted or completed.  
B.    Lease Subject to Project Documents.  
(1)    This Lease, and Tenant’s rights hereunder, are subject and subordinate to any all documents governing the maintenance, operation and use of the Project or the Building, including, without limitation, (i) the Declaration (as defined in Article 29.C.), and any rules or regulations promulgated by or on behalf of the “Developer” or “FPOC” under the Declaration, whether recorded or unrecorded, (ii) Chapter 91 License No. 11904 issued by the Massachusetts Department of Environmental Protection (“DEP”) for the Building, recorded with the Suffolk Registry of Deed in Book 42568, Page 73, and Chapter 91 License No. 11907 issued by DEP for all of the public realm areas of the Project, recorded with the Suffolk Registry of Deed in Book 42568, Page 89; (iii) Development Plan for the Fan Pier Development, Planned Development Area #54 approved by the Boston Redevelopment Authority (“BRA”) on November 14, 2001, and adopted by the Boston Zoning Commission on February 27, 2002, effective February 28, 2001, as amended by First Amendment to the Development Plan for the Fan Pier Development, Planned Development Area #54 approved by the Boston Redevelopment Authority on December 20, 2007, and adopted by the Boston Zoning Commission on January 30, 2008, effective January 30, 2008, and all agreements with the BRA or the City of Boston relating to the Building or the Project (collectively, and as may be amended or supplemented from time to time, the “Project Documents,” and each individually a “Project Document”).  
(2)     [Intentionally Omitted] 
(3)    [Intentionally Omitted]
(4)    The parties acknowledge and agree that all maintenance, repair, replacement, operation and administration of the “Common Areas and Facilities” (as defined in the Project Documents) are under the control of the Developer or FPOC.  Further the Developer’s or FPOC’s election to provide mechanical surveillance or to post security personnel in the Common Areas and Facilities is subject to the Developer’s or FPOC’s sole discretion.  Therefore, and notwithstanding anything to the contrary contained in this Lease, Landlord’s sole responsibility with respect to the maintenance, repair, replacement, operation, administration or the provision of surveillance or security in the Common Areas and Facilities, shall be to use commercially reasonable efforts to enforce the obligations of the Developer or FPOC under the Declaration.  Tenant hereby releases Landlord from any claim concerning the failure by Developer or FPOC to maintain any portion of the Common Areas and Facilities, other than a failure of Landlord to use commercially reasonable efforts to enforce the Developer or FPOC’s obligations under the Project Documents. 
ARTICLE 18. 
 
ESTOPPEL CERTIFICATE
Either party shall from time to time, upon written request by the other, execute, acknowledge and deliver to the requesting party (or the lender of the requesting party, as the case may be), within ten (10) business days after receipt of such request, a statement in writing certifying, without limitation:  (i) that this Lease is unmodified and in full force and effect (or if there have been modifications, identifying such modifications and certifying that the Lease, as modified, is in full force and effect); (ii) the dates to which Rent and any other charges have been paid; (iii) that to the best knowledge of Tenant, the requesting party is not in default under any provision of this Lease (or if the requesting party is in default, specifying each such default) and that no events or conditions exist which, with the passage of time or notice or both, would constitute a default on the part of the requesting party hereunder; (iv) the address to which notices to the non-requesting party shall be sent; (v) the amount of Tenant’s security deposit; and (vi) such other factual matters as the requesting party may reasonably request; it being understood that any such statement so delivered may be relied upon in connection with any lease, mortgage or transfer. No such certificate shall have the effect of amending this Lease, and in the event of any conflict between the terms of this Lease and any such certificate, this Lease shall control.
ARTICLE 19. 
 
DEFAULTS
A.    Tenant Defaults:  The occurrence of any of the following shall constitute a “default” or “event of default” by Tenant hereunder:
(a)    Tenant fails to pay when due any installment or other payment of Rent or any other amount owing to Landlord, and such failure continues for five (5) business days after notice thereof given by or on behalf of Landlord provided, however, that notice relating to Tenant’s failure to pay Monthly Base Rent shall only be required two (2) times per any twelve (12) month period and thereafter (during the remainder of such 12-month period) no notice shall be required in connection therewith prior to the same constituting a default; or
(b)    Tenant fails to keep in effect any insurance required to be maintained hereunder, and such failure continues for thirty (30) days after notice thereof given by or on behalf of Landlord; or
(c)    Tenant or any guarantor hereunder becomes insolvent, makes an assignment for the benefit of creditors, files a voluntary petition in bankruptcy or an involuntary petition in bankruptcy is filed against Tenant which petition is not dismissed within sixty (60) days of its filing; or
(d)    Tenant fails to cause to be released any mechanic’s liens filed against the Premises, the Building or the Project or any portion thereof within twenty (20) days after the date the same shall have been filed or recorded; or
(e)    Tenant fails to observe or perform according to the provisions of Article 17 or 18 within the time periods specified in such Articles; or
(f)    A receiver is appointed for Tenant’s business or assets and the appointment of such receiver is not vacated within sixty (60) days after such appointment; or
(g)    Tenant fails to perform or observe any of the other covenants, conditions or agreements contained herein on Tenant’s part to be kept or performed or breaches a representation made hereunder, and such failure shall continue for thirty (30) days after notice thereof from Landlord, or if such default is curable but cure cannot reasonably be effected within such thirty (30) day period, such default shall not be a default hereunder so long as Tenant promptly commences cure within ten (10) days after receipt of such notice and thereafter diligently prosecutes such cure to completion; or
(h)    Except for assignments or subleases under Article 16, if the interest of Tenant or any guarantor hereunder shall be offered for sale or sold under execution or other legal process if Tenant makes any transfer, assignment, conveyance, sale, pledge, disposition of all or a substantial portion of Tenant’s property.
All notices required to be given under this Article 19.A. shall be in lieu of, and not in addition to any notice requirements imposed by Law now or hereafter in effect.
If Tenant or any guarantor hereunder files a voluntary petition pursuant to the United States Bankruptcy Reform Act of 1978, as the same may be from time to time be amended (the “Bankruptcy Code”), or take the benefit of any insolvency act or be dissolved, or if an involuntary petition or proceeding for dissolution or liquidation is filed against Tenant pursuant to the Bankruptcy Code and said petition is not dismissed within sixty (60) days after such filing, or if a proceeding for the appointment of a trustee or a receiver is commenced for Tenant’s business or all or a portion of its assets and the appointment of such receiver is not vacated within sixty (60) days after such appointment, or if it shall make an assignment for the benefit of its creditors, then Landlord shall have all of the rights provided for in the event of nonpayment of the Rent.  Tenant hereby stipulates to the lifting of the automatic stay in effect and relief from such stay in the event Tenant files a petition under the Bankruptcy Code, for the purpose of Landlord pursuing its rights and remedies against Tenant and/or a guarantor under this Lease.
If any alleged default on the part of the Landlord hereunder occurs, Tenant shall give written notice to Landlord in the manner herein set forth and shall afford Landlord a reasonable opportunity to cure any such default.  In addition, Tenant shall send notice of such default by certified or registered mail, postage prepaid, to the holder of any Mortgage whose address Tenant has been provided in writing, and shall afford such Mortgage holder a reasonable opportunity to cure any alleged default on Landlord’s behalf. 
Any notice from Landlord to Tenant that claims or alleges a breach or default under this Lease shall state in prominent bold-face type “THIS IS A NOTICE OF DEFAULT UNDER A LEASE OF REAL PROPERTY, AND IMMEDIATE ACTION IS REQUIRED.”
ARTICLE 20. 
 
REMEDIES
A.    Landlord Remedies.  The remedies provided Landlord under this Lease are cumulative.  Upon the occurrence of any default by Tenant, and in addition to any and all other rights provided a landlord under law or equity for breach of a lease or tenancy by a tenant, Landlord shall have the right to pursue one or more of the following remedies:
(a)    Landlord may serve notice on Tenant that the Term and the estate hereby vested in Tenant and any and all other rights of Tenant hereunder shall cease on the date specified in such notice and on the specified date this Lease shall cease and expire as fully and with the effect as if the Term had expired for passage of time.
(b)    Without terminating this Lease in case of a default or if this Lease shall be terminated for default as provided herein, Landlord may re-enter the Premises, remove Tenant, or cause Tenant to be removed from the Premises in such manner as Landlord may deem advisable, with legal process.  In the event of re-entry without terminating this Lease, Tenant shall continue to be liable for all Rents and other charges accruing or coming due under this Lease which Rent shall automatically accelerate and become immediately due and payable.
(c)    If Landlord, without terminating this Lease, shall re-enter the Premises or if this Lease shall be terminated as provided in Article 20.A.(a) above, then, in either such event:
(i)    All Rent due from Tenant to Landlord shall thereupon become due and shall be paid up to the time of re-entry, dispossession or expiration, together with reasonable costs and expenses (including, without limitation, attorneys’ fees) of Landlord and without benefit of valuation and appraisement laws which Tenant hereby waives;
(ii)    Notwithstanding the foregoing, Landlord shall use commercially reasonable efforts to re-let the Premises after Tenant vacates the Premises after this Lease is terminated on account of a default by Tenant as further provided in Article 20.C. below.  
(iii)    If Landlord shall have terminated this Lease, Tenant shall also be liable to Landlord for all damages provided for at law and under this Lease resulting from Tenant’s breach, including, without limitation, a lump sum equal to the then net present value of the excess (if any) of the aggregate Rents reserved under the terms of this Lease for the balance of the Term together with all other sums payable hereunder as Rent for the balance of the Term, over the fair rental value of the Premises for that period determined as of the date of such termination. For purposes of this Article 20.A.(c)(iii), Tenant shall be deemed to include any guarantor or surety of the Lease.
(d)    Landlord may continue this Lease in effect after Tenant’s breach and abandonment and recover Rent as it becomes due, if Tenant has the right to sublet or assign, subject only to reasonable limitations.
(e)    Whether or not Landlord terminates this Lease, Landlord shall have the right, as Landlord chooses in its absolute discretion, (i) to terminate any or all subleases, licenses, concessions and other agreements entered into by Tenant in connection with its occupancy of the Premises and/or (ii) to maintain any or all such agreements in effect and succeed to Tenant’s interests in connection therewith (in which event Tenant shall cease to have any interest in any such agreement).
(f)    Attorneys’ Fees.
(i)    In any action to enforce the terms of this Lease, including any suit by Landlord for the recovery of Rent or possession of the Premises, the losing party shall reimburse the successful party for its reasonable attorneys’ fees incurred in such suit and such attorneys’ fees shall be deemed to have accrued prior to the commencement of such action and shall be paid whether or not such action is prosecuted to judgment.
(ii)    Should Landlord, without fault on Landlord’s part, be made a party to any litigation instituted by Tenant or by any third party against Tenant, or by or against any person holding under or using the Premises by license of Tenant, or for the foreclosure of any lien for labor or material furnished to or for Tenant or any such other person or otherwise arising out of or resulting from any act or transaction of Tenant or of any such other person, Tenant covenants to save and hold Landlord harmless from and against any judgment rendered against Landlord or the Premises or any part thereof and from and against all actual and reasonable costs and expenses, including reasonable attorneys’ fees, incurred by Landlord in connection with such litigation.
(iii)    When legal services are rendered by an attorney at law who is an employee of a party, attorneys’ fees incurred by that party shall be deemed to include an amount based upon the number of hours spent by such employee on such matters multiplied by an appropriate billing rate determined by taking into consideration the same factors, including but not limited by, the importance of the matter, time applied, difficulty and results, as are considered when an attorney not in the employ of a party is engaged to render such service.
(g)    In addition to the above, Landlord shall have any and all other rights provided a landlord at law or in equity, including, but not limited to, those remedies provided for by Laws now or hereafter in effect, for breach of a lease or tenancy by a tenant.
(h)    TO THE EXTENT PERMITTED BY LAW, EACH OF LANDLORD AND TENANT HEREBY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY CLAIM, ACTION PROCEEDING OR COUNTERCLAIM BY EITHER LANDLORD OR TENANT AGAINST THE OTHER OR ANY MATTER ARISING OUT OF OR IN ANY WAY CONNECTED WITH THIS LEASE, THE RELATIONSHIP OF LANDLORD AND TENANT, AND/OR TENANT’S USE OR OCCUPANCY OR THE PREMISES.
B.    Tenant Remedies.  Upon the occurrence of any default by Landlord, Tenant shall, except as otherwise expressly provided herein, have all rights and remedies provided hereunder and by law from time to time;  provided, however, that Tenant shall in no event have the right to terminate this Lease except as expressly provided herein or as provided by law.
C.    Mitigation of Damages.  Landlord and Tenant will each exercise commercially reasonable efforts to mitigate the damages caused by the other party’s breach of this Lease. Efforts to mitigate damages will not be construed as a waiver of the non-breaching party’s right to recover damages. For the purposes of this Article 20.C., marketing of the Premises in a manner similar to the way Landlord markets its other premises shall be deemed to satisfy Landlord’s obligation to use such “commercially 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 to re-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) to re-let the Premises before leasing other comparable vacant space in the Building (unless the prospective tenant is directly obtained and presented to Landlord as a result of Tenant’s marketing efforts and otherwise satisfies all other requirements of prospective tenants contained in this Lease), (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 to satisfy a typical office tenant’s obligations under an office lease.  In no event, however, shall Tenant’s liability hereunder be diminished or reduced if or to the extent such reasonable efforts of Landlord to re-let are not successful.
ARTICLE 21. 
 
QUIET ENJOYMENT
Landlord covenants and agrees with Tenant that so long as there exists no uncured default (i.e. beyond notice and cure periods) by Tenant, Tenant may peaceably and quietly enjoy the Premises subject, nevertheless, to the terms and conditions of this Lease, and Tenant’s possession will not be disturbed by anyone claiming by, through, or under Landlord.
ARTICLE 22. 
 
ACCORD AND SATISFACTION
No payment by Tenant or receipt by Landlord of an amount less than full payment of Rent then due and payable shall be deemed to be other than on account of Rent then due and payable, nor shall any endorsement or statement on any check or any letter accompanying any check or payment as Rent be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord’s right to recover the balance of such Rent or pursue any other remedy provided for in this Lease or available at law or in equity.  No payment by Landlord or receipt by Tenant of an amount less than the full amount then due and payable shall be deemed to be other than on account of the amount then due and payable, nor shall any endorsement or statement on any check or any letter accompanying any check or payment be deemed an accord and satisfaction, and Tenant may accept such check or payment without prejudice to Tenant’s right to recover the balance of such amount.
ARTICLE 23. 
 
SECURITY DEPOSIT
To secure the full and faithful performance by Tenant of all of the covenants, conditions and agreements set forth in this Lease to be performed by it, including, without limitation, the foregoing such covenants, conditions and agreements in this Lease which become applicable upon its termination by re-entry or otherwise, Tenant has deposited with Landlord the sum shown in Article 1 as a “Security Deposit.”  The Security Deposit shall be subject to the following terms and conditions:
(a)    The Security Deposit or any portion thereof may be applied to the curing of any default that may exist and continue beyond the expiration of applicable notice and cure periods, including but not limited to a breach for failure to pay Rent, without prejudice to any other remedy or remedies which Landlord may have on account thereof, and upon such application Tenant shall pay Landlord on demand the amount so applied which shall be added to the Security Deposit so the same will be restored to its original amount.
(b)    Should the Premises be conveyed by Landlord, the Security Deposit or any balance thereof shall be turned over to the Landlord’s grantee, and when the Security Deposit is actually turned over to such grantee, Tenant hereby releases Landlord from any and all liability with respect to the Security Deposit and its application or return, and Tenant agrees to look solely to such grantee for such application or return.
(c)    Unless the Security Deposit is in the form of a Letter of Credit, Landlord may commingle the Security Deposit with other funds, shall not be required to keep the Security Deposit in trust, and shall not be obligated to pay Tenant any interest.
(d)    The Security Deposit shall not be considered an advance payment of Rent or a measure of damages for any default by Tenant, nor shall it be a bar or defense to any actions by Landlord against Tenant.
(e)    If Tenant shall faithfully perform all of the covenants and agreements contained in this Lease on the part of the Tenant to be performed, and provided there exists no default by Tenant hereunder, the Security Deposit or any then remaining balance thereof, shall be returned to Tenant, without interest, within thirty (30) days after the expiration of the Term, provided that subsequent to the expiration of this Lease, Landlord may retain from the Security Deposit (i) an amount reasonably estimated by Landlord to cover potential Operating Expense reconciliation payments due with respect to the calendar year in which this Lease terminates or expires (such amount so retained shall not, in any event, exceed five percent (5%) of estimated Operating Expense payments due from Tenant for such calendar year through the date of expiration or earlier termination of this Lease and any amounts so retained and not applied to such reconciliation shall be returned to Tenant no later than ninety (90) days after the end of the calendar year in which such termination or expiration occurs (or if sooner, the date on which Landlord delivers such reconciliation), and (ii) any and all amounts permitted by law or this Article 23 (collectively hereinafter referred to as the “Contingent Amount”).  In the event Tenant has posted a Letter of Credit (as hereinafter defined) instead of cash, Tenant, at its option, may substitute cash at the expiration of the Term in an amount sufficient to satisfy the Contingent Amount, which amount shall be determined by Landlord, in its reasonable discretion as provided above. 
Tenant hereby waives any and all provisions of Laws that limit the types of defaults for which a landlord may claim sums from a security deposit, it being agreed that Landlord, in addition, may claim those sums specified in this Article 23 above and/or those sums reasonably necessary to compensate Landlord for any other loss or damage, foreseeable or unforeseeable, caused by a default by Tenant under this Lease.  Tenant further covenants that it will not assign or encumber the money deposited herein as a Security Deposit and that neither Landlord nor its successors or assigns shall be bound by any such assignment, encumbrance, attempted assignment or attempted encumbrance.
(f)    The Security Deposit shall be in the form of a letter of credit, which Tenant shall deliver to Landlord (as beneficiary), and a copy to Landlord’s attorney, a standby letter of credit (“Letter of Credit”), in form and content reasonably satisfactory to Landlord, simultaneously with Tenant’s execution and delivery of this Lease to Landlord.  The Letter of Credit shall be, among other things:
		
	(1)
	subject to International Standby Practices 1998, International Chamber of Commerce Publication No. 590;

		
	(2)
	irrevocable and unconditional, subject to (1) above;

		
	(3)
	in the amount of the required Security Deposit;

		
	(4)
	conditioned for payment solely upon presentation of the Letter of Credit and a sight draft certifying to the issuer of the Letter of Credit the existence of such grounds or circumstances upon which Landlord is permitted to make such draw, and

		
	(5)
	transferable one or more times by Landlord without the consent of Tenant.

Tenant acknowledges and agrees that it shall pay upon Landlord’s demand, as Additional Rent, any and all costs or fees charged in connection with the Letter of Credit that arise due to: (i) Landlord’s sale or transfer of all or a portion of the Property on one (1) occasion only, or (ii) the addition, deletion, or modification of any beneficiaries under the Letter of Credit.  The Letter of Credit shall be issued by a member of the New York Clearing House Association or a commercial bank or trust company satisfactory to Landlord, having banking offices at which the Letter of Credit may be drawn upon in Boston, Massachusetts or Hartford, Connecticut and a net worth reasonably acceptable to Landlord. Landlord hereby approves TD Bank as an issuing bank. The Letter of Credit shall expire not earlier than twelve (12) months after the date of delivery thereof to Landlord and shall provide that same shall be automatically renewed for successive twelve (12) month periods through a date which is not earlier than sixty (60) days after the expiration date, or any renewal or extension thereof, unless written notice of non-renewal has been given by the issuing bank to Landlord by registered or certified mail, return receipt requested (or by reputable overnight delivery), not less than sixty (60) days prior to the expiration of the current period.  If the issuing bank does not renew the Letter of Credit, and if Tenant does not deliver a substitute Letter of Credit or cash in lieu thereof at least thirty (30) days prior to the expiration of the current period, then Landlord shall have the right to draw on the existing Letter of Credit and maintain such funds as a cash security deposit.  With respect to draws on the Letter of Credit:
		
	(x)
	Landlord may use, apply, or retain the proceeds of the Letter of Credit to the same extent that Landlord may use, apply, or retain the cash Security Deposit, as set forth above in this Article 23 or elsewhere in this Lease;

		
	(y)
	Landlord may draw on the Letter of Credit, in whole or in part, from time to time, at Landlord’s election, to the same extent that Landlord may draw on the cash Security Deposit, as set forth above in this Article 23 or elsewhere in this Lease; and

		
	(z)
	If Landlord partially draws down the Letter of Credit, Tenant shall within ten (10) days after Landlord gives Tenant notice thereof, restore all amounts drawn by Landlord, or substitute cash security instead.

Notwithstanding any of the foregoing to the contrary, provided that, at each such time, there then exists no default of Tenant and this Lease is then in full force and effect, then Tenant shall be entitled to reduce the face amount of a cash Security Deposit (or the Letter of Credit, as the case may be) to: (i) $525,967.76 on the fourth (4th) anniversary of the Rent Commencement Date, and (ii) $394,475.82 on the fifth (5th) anniversary of the Rent Commencement Date, and Landlord shall accept a substitute Letter of Credit for such reduced amounts or an endorsement to the existing Letter of Credit. Tenant hereby agrees to cooperate, at its expense with Landlord to promptly execute and deliver to Landlord any and all modifications, amendments and replacements of the Letter of Credit, as Landlord may reasonably request to carry out the terms and conditions of this Article 23.

In the event the issuer of any Letter of Credit held by Landlord hereunder is insolvent or 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 issuer, or if Landlord is unable to effectuate a transfer of the Letter of Credit with the issuer of such letter of credit, then, effective as of the date of such occurrence, said Letter of Credit shall be deemed to not meet the requirements of this Article 23 and Tenant shall, within five (5) business days after receipt of written notice from Landlord, deliver to Landlord a replacement Letter of Credit which otherwise meets the requirements of this Article 23 (and Tenant’s failure to do so shall, notwithstanding anything in this Lease to the contrary, constitute an event of default for which there shall be no notice or grace or cure periods being applicable thereto other than the aforesaid five-day period); or, alternatively, Tenant shall, within such five (5)-day period deliver cash to Landlord in the amount required by this Article 23.

ARTICLE 24. 
 
BROKERAGE COMMISSION
Landlord and Tenant represent and warrant to each other that neither has dealt with any broker, finder or agent except for the Broker(s) identified in Article 1.  Tenant represents and warrants to Landlord that (except with respect to the Broker(s) identified in Article 1 and with whom Landlord has entered into a separate brokerage agreement) no broker, agent, commission salesperson, or other person has represented Tenant in the negotiations for and procurement of this Lease and of the Premises and that no commissions, fees, or compensation of any kind are due and payable in connection herewith to any broker, agent commission salesperson, or other person.  Tenant agrees to indemnify and hold harmless Landlord from and against any and all loss, liabilities, claims, suits, or judgments (including, without limitation, reasonable attorneys’ fees and court costs incurred in connection with any such claims, suits, or judgments, or in connection with the enforcement of this indemnity) for any fees, commissions, or compensation of any kind which arise out of or are in any way connected with any claimed agency relationship not referenced in Article 1.  Landlord agrees to indemnify and hold harmless Tenant from and against any and all loss, liabilities, claims, suits, or judgments (including, without limitation, reasonable attorneys’ fees and court costs incurred in connection with any such claims, suits, or judgments, or in connection with the enforcement of this indemnity) for any fees, commissions, or compensation of any kind which arise out of or are in any way connected with any claimed agency relationship with Landlord.
ARTICLE 25. 
 
FORCE MAJEURE
Landlord shall be excused for the period of any delay in the performance of any obligation hereunder, except for any delay in the payment of money or any delay in the cure of any default which may be cured by the payment of money, when prevented from so doing by a cause or causes beyond its control, including all labor disputes, civil commotion, war, war-like operations, invasion, rebellion, hostilities, military or usurped power, sabotage, governmental regulations or controls, fire or other casualty, inability to obtain any material, services or financing, or through acts of God (collectively, “Force Majeure”). Tenant shall similarly be excused for delay in the performance of any obligation hereunder; provided:
(a)    nothing contained in this Article 25 or elsewhere in this Lease shall be deemed to excuse or permit any delay in the payment of Rent, or any delay in the cure of any default which may be cured by the payment of money; and
(b)    no reliance by Tenant upon this Article 25 shall limit or restrict in any way Landlord’s right of self-help as provided in this Lease.
ARTICLE 26. 
 
PARKING
(a)    Tenant shall be entitled to obtain, and pay for, contracts with the Parking Garage operator for the number of parking access devices set forth in Article 1 permitted use of such number of unreserved parking spaces in the Parking Garage, in areas, if any, as may be designated by Landlord or the Parking Garage operator for occupants of the Building, notwithstanding the number of Tenant’s employees, customers or invitees.  The parking contracts shall be for unassigned spaces and the monthly rate to be paid by Tenant and its employees shall be the prevailing monthly parking rate charged by the Parking Garage operator, which parking rate may change at any time and from time to time, as determined by such Parking Garage operator.  In the event Tenant fails to make any payment of the monthly parking charge within thirty (30) days after receipt of notice from Landlord that the same was not paid when due, then Landlord may revoke those parking contracts as to which payment was not made, and Landlord shall be under no obligation to obtain replacement parking contracts.  Tenant shall be responsible for the full amount of any taxes imposed by any governmental authority in connection with the use of the Parking Garage by Tenant. Failure to pay any monthly parking charge shall in no event be grounds for any claim of a default by Tenant under this Lease. 
(b)    If requested by Landlord, Tenant shall notify Landlord of the license plate number, year, make and model of the automobiles entitled to use the Parking Garage under such contracts and if requested by Landlord, such automobiles shall be identified by electronic or other identification devices provided by Landlord or the Parking Garage operator, and only such designated automobiles shall be permitted to use access control devices provided to monthly contract holders in the Parking Garage.  The Parking Garage will be operated in whole or in part as a public parking garage, and at Landlord’s sole election, Landlord may make validation stickers available to Tenant for the use of public parking spaces, provided, however, if Landlord makes validation stickers available to any other office tenant in the Building, Landlord shall make such validation stickers available to Tenant.  If Landlord has instituted a vehicle identification system or other parking procedure and Tenant’s employees, customers or invitees do not comply with any such procedure, then in any of such events, Landlord shall be entitled to, without any liability to Tenant, its employees, customers or invitees, remove any vehicles not complying with Landlord’s procedures.  Tenant acknowledges and agrees that Landlord may, without incurring any liability to Tenant and without any abatement of Rent under this Lease, from time to time, close-off or restrict access to the Parking Garage for purposes of permitting or facilitating construction, alteration or improvement.  Landlord may delegate its responsibilities hereunder to a parking operator or a lessee of the Parking Garage in which case such parking operator or lessee shall have all the rights of control attributed hereby to the Landlord.
(c)    Tenant may not assign, transfer, sublease or otherwise alienate its right to use of the Parking Garage, except in connection with a sublease of the Premises or an assignment of this Lease, without Landlord’s prior written consent.  Tenant’s continued right to use the Parking Garage is conditioned upon Tenant abiding by the terms of any parking contracts, and all rules and regulations which are prescribed from time to time for the orderly operation and use of the Parking Garage, Tenant’s cooperation in seeing that Tenant’s employees and visitors also comply with such rules and regulations, and Tenant not being in default under this Lease.
(d)    Tenant acknowledges that the Parking Garage is subject to the provisions of the South Boston Parking Freeze Regulations and to one or more Parking Freeze Permits issued thereunder by the City of Boston Air Pollution Control Commission, which regulations and permits require that twenty percent (20%) of the total parking supply in the Parking Garage be set aside for Off-Peak use, and not be available weekdays between 7:30 a.m. and 9:30 a.m.  Tenant acknowledges that the administration of such requirement may from time to time limit the ability of certain of the monthly parkers to enter the Parking Garage between 7:30 a.m. and 9:30 a.m.
ARTICLE 27. 
 
HAZARDOUS MATERIALS
A.    Definition of Hazardous Materials.  The term “Hazardous Materials” for purposes hereof shall mean any chemical, substance, materials or waste or component thereof which is at the time in question listed, defined or regulated as a hazardous or toxic chemical, substance, materials or waste or component thereof by any federal, state or local governing or regulatory body having jurisdiction, or which would trigger any employee or community “right-to-know” requirements adopted by any such body, or for which any such body has adopted any requirements for the preparation or distribution of a materials safety data sheet (“MSDS”).  The term “Hazardous Material” includes, without limitation, any material, waste or substance which is (i) included within the definitions of “hazardous substances,” “hazardous materials,” “toxic substances” or “solid waste” in or pursuant to any environmental Law, or subject to regulation under any environmental Law, (ii) listed in the United States Department of Transportation Optional Hazardous Material Table, 49 C.F.R. § 172.101, as to date or hereafter amended, or in the United States Environmental Protection Agency List of Hazardous Substances and Reportable Quantities, 40 C.F.R. Part 302, as to date or hereafter amended, (iii) an explosive, radioactive, asbestos, polychlorinated biphenyl, oil or petroleum product, (iv) designated as a “Hazardous Substance” pursuant to Section 311 of the Federal Water Pollution Control Act (33 U.S.C. § 1317), (v) defined as a “Hazardous Waste” pursuant to Section 1004 of the Federal Resource Conservation and Recovery Act, 42 U.S.C. § 6901 et seq. (42 U.S.C. § 6903), (vi) defined as a “Hazardous Substance” pursuant to Section 101 of the Comprehensive Environmental Response, Compensation and Liability Act, 42 U.S.C. § 9601 et seq. (42 U.S.C. § 9601), or (vii) any substance deemed to be a “Hazardous Material” by any present or future federal, state or local Law, statute, regulation ordinance, or any judicial or administrative order or judgment thereunder, because it effects the health, industrial hygiene or the environmental or ecological conditions on, under or about the Premises or the Building.
B.    No Hazardous Materials.  Tenant shall not transport, use, store, maintain, generate, manufacture, handle, dispose, release or discharge any Hazardous Materials.  However, the foregoing provisions shall not prohibit the transportation to and from, and use, storage, maintenance and handling within the Premises of Hazardous Materials customarily used in the business or activity expressly permitted to be undertaken in the Premises under Article 6, provided: (a) such Hazardous Materials shall be used and maintained only in such quantities as are reasonably necessary for the Permitted Use of the Premises and the ordinary course of Tenant’s business therein,  in accordance with applicable Law; (b) such Hazardous Materials shall not be disposed of, released or discharged in the Building, and shall be transported to and from the Premises in compliance with all applicable Laws, and as Landlord shall reasonably require; (c) if any applicable Law or Landlord’s trash removal contractor requires that any such Hazardous Materials be disposed of separately from ordinary trash, Tenant shall make arrangements, at Tenant’s expense, for such disposal directly with a qualified and licensed disposal company at a lawful disposal site (subject to scheduling and approval by Landlord); and (d) any remaining such Hazardous Materials shall be completely, properly and lawfully removed from the Building upon expiration or earlier termination of this Lease.  Any clean up, remediation and removal work shall be subject to Landlord’s prior written approval (except in emergencies), and shall include, without limitation, any testing, investigation, and the preparation and implementation of any remedial action plan required by any governmental body having jurisdiction or reasonably required by Landlord.  If Landlord or any Lender or governmental body arranges for any tests or studies showing that this Article 27 has been violated by Tenant, Tenant shall pay for the costs of such tests.
C.    Notices To Landlord.  Tenant shall promptly notify Landlord of:  (i) any enforcement, cleanup or other regulatory action taken or threatened in writing by any governmental or regulatory authority against Tenant with respect to the presence of any Hazardous Materials on the Premises or the migration thereof from the Premises to other property; (ii) any demands or claims made or threatened in writing by any party against Tenant relating to any loss or injury resulting from any Hazardous Materials on the Premises; (iii) any release, discharge or non-routine, improper or unlawful disposal or transportation of any Hazardous Materials on or from the Premises or in violation of this Article 27 of which Tenant obtains knowledge; and (iv) any matters where Tenant is required by Law to give a notice to any governmental or regulatory authority respecting any Hazardous Materials on the Premises.  Landlord shall have the right (but not the obligation) to join and participate, at its expense, as a party, in any legal proceedings or actions affecting the Premises initiated in connection with any environmental, health or safety Law.  At such times as Landlord may reasonably request, if Tenant is using the Premises for other than business or professional offices, Tenant shall provide Landlord with a written list, certified to be true and complete, identifying any Hazardous Materials then used, stored or maintained upon the Premises, the use and approximate quantity of each such material, a copy of any MSDS issued by the manufacturer therefor and such other information as Landlord may reasonably require or as may be required by Law.  The foregoing requirement shall not apply to certain Hazardous Materials customarily found in offices in first-class office buildings in the Boston market and otherwise permitted by applicable Law, such as, by way of example and not limitation, toner for copiers, ink for printers and customary cleaning products.
D.    Indemnification.  If any Hazardous Materials are released, discharged or disposed of by Tenant or any other occupant of the Premises, or their employees, agents, invitees or contractors, on or about the Building in violation of the foregoing provisions, Tenant shall immediately, properly and in compliance with applicable Laws clean up, remediate and remove the Hazardous Materials from the Building and any other affected property and clean or replace any affected personal property (whether or not owned by Landlord), at Tenant’s expense (without limiting Landlord’s other remedies therefor).  Tenant shall further be required to indemnify, hold harmless and defend (by counsel reasonably acceptable to Landlord) Landlord, and it attorneys and agents from and against any and all claims, demands, liabilities, losses, damages, penalties, forfeitures, judgments or expenses (including attorneys’ fees) or death or injury to any person or damage to any property whatsoever, arising directly or indirectly arising out of or attributable to:  (i) a violation of the provisions of this Article 27 by Tenant, Tenant’s occupants, employees, contractors or agents; (ii) the presence in, on, under or about the Premises or discharge in or from the Premises of any Hazardous Materials placed in, under or about the Premises by Tenant or at Tenant’s direction, excluding any tenant improvement work done by Landlord; (iii) Tenant’s use, analysis, storage, transportation, disposal, release, threatened release, discharge or generation of Hazardous Materials to, in, on, under, about or from the Premises; or (iv) Tenant’s failure to comply with any Hazardous Materials Law applicable hereunder to Tenant.  Any clean up, remediation and removal work shall be subject to Landlord’s prior written approval (except in emergencies), and shall include, without limitation, any testing, investigation, and the preparation and implementation of any remedial action plan required by any governmental body having jurisdiction or reasonably required by Landlord. Notwithstanding any provision of this Lease to the contrary, Tenant shall in no event have any liability (by way of indemnification or otherwise) for removal or remediation of any Hazardous Materials from the Premises or the Property to the extent that such Hazardous Materials (A) existed in, on or under the Premises or the Property, as the case may be, on the Commencement Date, or (B) were placed or released in, on or under the Premises other than by the act or omission of Tenant or its agents, employees, or contractors or anyone claiming by, through or under Tenant. 
Landlord represents and warrants to Tenant that, as of the Commencement Date, the Premises will be free of unlawful levels or concentrations of any Hazardous Materials.  Landlord will indemnify, defend (by counsel reasonably acceptable to Tenant), protect, and hold Tenant and each of Tenant’s employees, agents, attorneys, successors and assigns, free and harmless from and against any and all claims, liabilities, penalties, forfeitures, losses or expenses (including attorney’s fees) or death of or injury to any person or damage to any property whatsoever, arising from or caused in whole or in part, directly or indirectly, by:
(a)    the presence in, on, under or about the Premises or the Building or discharge in or from the Premises or the Building of any Hazardous Materials placed, in, on, under or about the Premises or the Building by Landlord or at Landlord’s direction; or
(b)    Landlord’s use, analysis, storage, transportation, disposal, release, threatened release, discharge or generation of Hazardous Materials to, in, on, under, about or from the Premises or the Building; or
(c)    Landlord’s failure to comply with any Hazardous Materials Law.
The obligations of each party pursuant to this Article 27 include, without limitation, and whether foreseeable or unforeseeable, all costs of any required or necessary repair, cleanup or detoxification or decontamination of the Premises or the Building, and the preparation and implementation of any closure, remedial action or other required plans in connection therewith, and survives the expiration or earlier termination of the term of the Lease.
ARTICLE 28.

In any such event, the square footage of the Retail Component shall be revised to reflect the reallocation of premises.
S.    “Tax” or “Taxes” shall mean:
1.1    all real property taxes and assessments levied against the Building by any governmental or quasi-governmental authority.  To the extent not included in Operating Expenses, the foregoing shall include all federal, state, county, or local governmental, special district, improvement district, municipal or other political subdivision taxes, fees, levies, assessments, charges or other impositions of every kind and nature, whether general, special, ordinary or extraordinary, respecting the Building, including without limitation, real estate taxes, general and special assessments, interest on any special assessments paid in installments, transit taxes,  taxes based upon the receipt of rent, personal property taxes imposed upon the fixtures, machinery, equipment, apparatus, appurtenances, furniture and other personal property owned by Landlord and used in connection with the Building which Landlord shall pay during any calendar year, any portion of which occurs during the Term (without regard to any different fiscal year used by such government or municipal authority except as provided below), provided, however, that any taxes which shall be levied on the rentals of the Building shall be determined as if the Building were Landlord’s only property, and provided further that in no event shall the term “taxes or assessment,” as used herein, include any net federal or state income taxes levied or assessed on Landlord, unless such taxes are a specific substitute for real property taxes, or any corporate or franchise taxes, inheritance, gift or transfer taxes.  Such term shall, however, include gross taxes on rentals.  Expenses incurred by Landlord for tax consultants and in contesting the amount or validity of any such taxes or assessments shall be included in such computations.
1.2    to the extent the same are not included in Operating Expenses, all “assessments,” including so-called special assessments, license tax, business license tax, levy, charge, penalty or tax imposed by any authority having the direct power to tax, including any city, county, state or federal government, or any school, agricultural, lighting, water, drainage, or other improvement or special district thereof, against the Premises or the Building or any legal or equitable interest of Landlord therein.  For the purposes of this Lease, any special assessments shall be deemed payable in such number of installments as is permitted by law, whether or not actually so paid.  If the Building is not fully built-out for occupancy by tenants or is otherwise not leased or assessed at full market value during the Base Year for Taxes or during any particular Comparison Year, then the Taxes for the Base Year or the particular Comparison Year will be adjusted to reflect the undiscounted fair market value of the Building as shown on the City of Boston Tax Assessor’s field card for the Building as of the Rent Commencement Date.  If the method of taxation of real estate prevailing to the time of execution hereof shall be, or has been altered, so as to cause the whole or any part of the taxes now, hereafter or theretofore levied, assessed or imposed on real estate to be levied, assessed or imposed on Landlord, wholly or partially, as a capital levy or otherwise, or on or measured by the rents received therefrom, then such new or altered taxes attributable to the Building shall be included within the term real estate taxes, except that the same shall not include any enhancement of said tax attributable to other income of Landlord.  All of the items set forth in the preceding clauses S.1.1 and S.1.2 are collectively referred to as the “Tax” or “Taxes”.
All other capitalized terms shall have the definition set forth in the Lease.
ARTICLE 30.

Landlord shall not be liable to Tenant for violation of any such rules and regulations, or for the breach of any covenant or condition in any lease by any other tenant in the Building.  A waiver by Landlord of any rule or regulation for any other tenant shall not constitute nor be deemed a waiver of that rule or regulation for Tenant. Landlord shall not apply and enforce any Rules or Regulations in a discriminatory manner.  In the case of any conflict between this Lease and any rule or regulation, this Lease shall control.

D.    TRANSFERS.
The term “Landlord” appearing herein shall mean only the owner of the Building from time to time and, upon a sale or transfer of its interest in the Building, the then landlord and transferring party shall have no further obligations or liabilities for matters accruing after the date of transfer of that interest, provided (and only to the extent) that the transferee or successor to Landlord has assumed such liabilities and obligations.  Tenant, upon receipt of written notice of such sale or transfer, agrees to attorn to the transferee and shall look solely to the successor owner and transferee of the Building, as the lessor under this Lease, for performance of Landlord’s obligations arising hereunder to the extent so assumed.  Tenant shall, within ten (10) business days after request, execute such further instruments or assurances (in form and substance reasonably acceptable to Tenant and such transferee) as such transferee may reasonably deem necessary to evidence or confirm such attornment.
E.    [INTENTIONALLY OMITTED].
F.    TENANT FINANCIAL STATEMENTS.
Upon the written request of Landlord, and to the extent that the same are not otherwise publicly available, Tenant shall submit financial statements for its most recent financial reporting period and for the prior Lease Year. Landlord shall make such request no more than twice during any Lease Year, unless such request is in connection with an uncured event of default hereunder or any prospective sale, financing or refinancing of the Building, in which event there shall be no such limitation.  All such financial statements shall be certified as true and correct in all material respects by the responsible officer or partner of Tenant and if Tenant is then in default hereunder (beyond all applicable notice and grace periods), the financial statements shall be certified by an independent certified public accountant.
G.    RELATIONSHIP OF THE PARTIES.
Nothing contained in this Lease shall be construed by the parties hereto, or by any third party, as constituting the parties as principal and agent, partners or joint venturers, nor shall anything herein render either party (other than a guarantor) liable for the debts and obligations of any other party, it being understood and agreed that the only relationship between Landlord and Tenant is that of Landlord and Tenant.
H.    ENTIRE AGREEMENT; MERGER; SEVERABILITY.
This Lease and any Exhibits or Addenda hereto, embody the entire agreement and understanding between the parties respecting the Lease and the Premises and supersedes all prior negotiations, agreements and understandings between the parties, all of which are merged herein. No provision of this Lease may be modified, waived or discharged except by an instrument in writing signed by the party against which enforcement of such modification, waiver or discharge is sought.  Any provision of this Lease which shall prove to be invalid, void or illegal shall in no way affect, impact, impair or invalidate any other provision hereof and such other provisions shall remain in full force and effect.
I.    NO REPRESENTATION BY LANDLORD.
Neither Landlord nor any agent of Landlord has made any representations, warranties, or promises with respect to the Premises or the Building except as expressly set forth herein.
J.    LIMITATION OF LIABILITY.
Notwithstanding anything in this Lease to the contrary, any remedy of Tenant for the collection of a judgment (or other judicial process) requiring the payment of money by Landlord in the event of any default by Landlord hereunder or any claim, cause of action or obligation, contractual, statutory or otherwise by Tenant against Landlord concerning, arising out of or relating to any matter relating to this Lease and all of the covenants and conditions or any obligations, contractual, statutory, or otherwise set forth herein, shall be limited solely and exclusively to an amount which is equal to the interest of Landlord in and to the Building.  Any judgments rendered against Landlord shall be satisfied solely out of the rents, issues and profits of the Building and the proceeds of sale of Landlord’s interest in the Building.  No other property or assets of Landlord, or any member, officer, director, shareholder, partner, trustee, agent, servant or employee of Landlord (the “Representatives”) shall be subject to levy, execution or other enforcement procedure for the satisfaction of Tenant’s remedies under or with respect to this Lease, Landlord’s obligations to Tenant, whether contractual, statutory or otherwise, the relationship of Landlord and Tenant hereunder, or Tenant’s use or occupancy of the Building.  Tenant further understands that any liability, duty or obligation of Landlord to Tenant, shall automatically cease and terminate as of the date that Landlord or any of Landlord’s Representatives no longer have any right, title or interest in or to the Building, to the extent that the successor to Landlord has assumed the obligations of Landlord under this Lease as provided above..  The provisions hereof shall inure to Landlord’s successors and assigns including any Lender.  The foregoing provisions are not intended to relieve Landlord from the performance of any of Landlord’s obligations under this Lease, but only to limit the personal liability of Landlord in case of recovery of a judgment against Landlord; nor shall the foregoing be deemed to limit Tenant’s rights to obtain injunctive relief or specific performance or other remedy which may be accorded Tenant by law or under this Lease.  If Tenant claims or asserts that Landlord has violated or failed to perform a covenant under the Lease, then except as may otherwise be expressly provided in this Lease, Tenant’s sole remedy shall be an action for specific performance, declaratory judgment or injunction and in no event shall Tenant be entitled to any money damages in any action or by way of set off, defense or counterclaim and Tenant hereby specifically waives the right to any money damages or other remedies for any such violation or failure. Neither Tenant’s officers, directors, trustees, shareholders, agents or employees, nor their respective partners, heirs, successors and assigns, shall ever have any personal liability for the obligations of Tenant hereunder, and Landlord hereby expressly waives and releases such personal liability on behalf of itself and all persons claiming by, through or under Landlord.
K.    NOTICE OF LEASE.
Tenant agrees that it will not record this Lease; however, each party hereto agrees, concurrently with the execution of this Lease, to execute a so-called notice of lease in recordable form and complying with applicable Law and reasonably satisfactory to Landlord’s and Tenant’s respective attorneys.  In no event shall such document set forth the rent or other charges payable by Tenant under this Lease; and any such document shall expressly state that it is executed pursuant to the provisions contained in this Lease, and is not intended to vary the terms and conditions of this Lease.
L.    NO WAIVERS.
Failure of Landlord or Tenant to insist upon strict compliance by the other party of any condition or provision of this Lease shall not be deemed a waiver by the first party of that condition.  No waiver by Landlord or Tenant of any provision of this Lease shall be deemed to be a waiver of any other provision hereof or of any subsequent breach by the other party of the same or any other provision.  No provision of this Lease may be waived by Landlord or Tenant, except by an instrument in writing executed by Landlord or Tenant, as applicable, and except as otherwise expressly provided in this Lease.  Landlord’s or Tenant’s consent to or approval of any act by the other party requiring the first party’s consent or approval shall not be deemed to render unnecessary the obtaining of such first party’s consent to or approval of any subsequent act of the other party, whether or not similar to the act so consented to or approved.  No act or thing done by Landlord or a Landlord agent during the Term of this Lease shall be deemed an acceptance of a surrender of the Premises, and no agreement to accept such surrender shall be valid unless in writing and signed by Landlord.  Similarly, this Lease cannot be amended except by a writing signed by Landlord and Tenant.  Any payment by one party to another hereunder or receipt by a party of an amount less than the total amount then due hereunder shall be deemed to be in partial payment only thereof and not a waiver of the balance due or an accord and satisfaction, notwithstanding any statement or endorsement to the contrary on any check or any other instrument delivered concurrently therewith or in reference thereto.  Accordingly, a party may accept any such amount and negotiate any such check without prejudice to such party’s right to recover all balances due and owing and to pursue its other rights against the other party under this Lease, regardless of whether the first party makes any notation on such instrument of payment or otherwise notifies the other party that such acceptance or negotiation is without prejudice to the first party’s rights.
M.    SUCCESSORS AND ASSIGNS.
The conditions, covenants and agreements contained herein shall be binding upon and inure to the benefit of the parties hereto and their respective heirs, executors, administrators, successors and assigns.
		
	N.
	GOVERNING LAW; INDEPENDENT COVENANTS; WAIVER.

This Lease shall be governed by the law of the Commonwealth of Massachusetts.  No conflicts of law rules of any state or country (including, without limitation, the conflicts of law rules of the Commonwealth of Massachusetts) shall be applied to result in the application of any substantive or procedural laws of any state or country other than the Commonwealth of Massachusetts.  All controversies, claims, actions or causes of action arising between the parties hereto and/or their respective successors and assigns, shall be brought, heard and adjudicated by the courts of the Commonwealth of  Massachusetts, with venue in the County of  Suffolk.  Each of the parties hereto hereby consents to personal jurisdiction by the courts of the  Commonwealth of  Massachusetts in connection with any such controversy, claim, action or cause of action, and each of the parties hereto consents to service of process by any means authorized by the law of the Commonwealth of Massachusetts and consent to the enforcement of any judgment so obtained in the courts of the Commonwealth of Massachusetts on the same terms and conditions as if such controversy, claim, action or cause of action had been originally heard and adjudicated to a final judgment in such courts.  Each of the parties hereto further acknowledges that the laws and courts of the Commonwealth of Massachusetts were freely and voluntarily chosen to govern this Lease and to adjudicate any claims or disputes hereunder. 
Tenant waives all rights (i) to any abatement, suspension, deferment, reduction or deduction of or from Rent, and (ii) to quit, terminate or surrender this Lease or the Premises or any part thereof, except, in either case, as expressly provided in this Lease.  Tenant hereby acknowledges and agrees that the obligations of Tenant hereunder shall be separate and independent covenants and agreements, that Rent shall continue to be payable in all events and that the obligations of Tenant hereunder shall continue unaffected, unless the requirement to pay or perform the same shall have been terminated pursuant to an express provision of this Lease.  Landlord and Tenant each acknowledges and agrees that the independent nature of the obligations of Tenant hereunder represents fair, reasonable and accepted commercial practice with respect to the type of property subject to this Lease, and that this agreement is the product of free and informed negotiation during which both Landlord and Tenant were represented by counsel skilled in negotiating and drafting commercial leases in Massachusetts, and that the acknowledgements and agreements contained herein are made with full knowledge of the holding in Wesson v. Leone Enterprises, Inc., 437 Mass. 708 (2002).  Such acknowledgements, agreements and waivers by Tenant are a material inducement to Landlord entering into this Lease.

Q.    COUNTERPARTS.
This Lease may be executed in one (1) or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.
R.    TIME OF ESSENCE.
Each covenant herein is a condition and time is of the essence with respect to the performance of every provision of this Lease.
S.    SURVIVAL OF OBLIGATIONS.
Any obligations of Tenant occurring prior to the expiration or earlier termination of this Lease shall survive such expiration or earlier termination.
T.    CONFIDENTIALITY.
Tenant acknowledges that the material financial terms  of this Lease and any related documents are confidential information. Tenant shall use commercially reasonable efforts to keep such confidential information strictly confidential and shall not disclose such confidential information to any person or entity other than Tenant’s financial, legal and space planning consultants and any proposed subtenants or assignees.
U.    NO OPTION.
THE SUBMISSION OF THIS LEASE BY LANDLORD, ITS AGENT OR REPRESENTATIVE FOR EXAMINATION OR EXECUTION BY TENANT DOES NOT CONSTITUTE AN OPTION OR OFFER TO LEASE THE PREMISES UPON THE TERMS AND CONDITIONS CONTAINED HEREIN OR A RESERVATION OF THE PREMISES IN FAVOR OF TENANT, IT BEING INTENDED HEREBY THAT THIS LEASE SHALL ONLY BECOME EFFECTIVE UPON THE EXECUTION HEREOF BY LANDLORD AND DELIVERY OF A FULLY EXECUTED LEASE TO TENANT.
V.    USE OF BUILDING NAME; IMPROVEMENTS.
Tenant shall not be allowed to use the name, picture or representation of the Building, or words to that effect, or any logo or trademark associated with the Project, in connection with any business carried on in the Premises or otherwise (except that Tenant may use the name of the Building as Tenant’s address) without the prior written consent of Landlord.  In the event that Landlord undertakes any additional improvements on the property on which the Building is located including, but not limited to, new construction or renovation or additions to the existing improvements, Landlord shall not be liable to Tenant for any noise, dust, vibration or interference with access to the Premises or disruption in Tenant’s business caused thereby.
W.    RIGHT OF LANDLORD TO PERFORM.
All covenants and agreements to be performed by Tenant under any of the terms of this Lease shall be performed by Tenant at Tenant’s sole cost and expense and without any abatement of Rent.  If Tenant shall fail to pay any sum of money, other than Rent, required to be paid by it hereunder or shall fail to perform any other act on its part to be performed hereunder, and such failure shall continue beyond any applicable notice and cure period set forth in this Lease, Landlord may, but shall not be obligated to, without waiving or releasing Tenant from any obligations of Tenant, make any such payment or perform any such other act on Tenant’s part to be made or performed as is in this Lease provided.  All sums so paid by Landlord and all reasonable incidental costs, together with interest thereon at the Default Rate from the date of such payment by Landlord, shall be payable to Landlord on demand and Tenant covenants to pay any such sums, and Landlord shall have (in addition to any other right or remedy of Landlord) the same rights and remedies in the event of the nonpayment thereof by Tenant as in the case of default by Tenant in the payment of the Rent.
X.    ACCESS, CHANGES IN BUILDING, FACILITIES, NAME.
(i)    Every part of the Building except the inside surfaces of all walls, windows and doors bounding the Premises (including exterior building walls, core corridor walls and doors and any core corridor entrance), and any space in or adjacent to the Premises used for shafts, stacks, pipes, conduits, fan rooms, ducts, electric or other utilities, sinks or other building facilities, and the use thereof, as well as access thereto through the Premises for the purposes of operation, maintenance, decoration and repair, are reserved to Landlord, provided that Tenant shall have reasonable, non-exclusive access through the risers, shafts and conduits serving the Premises to other portions of the Building (including the roof and mechanical floors) serving the Premises, and to utility connections at common connection points for the installation, repair and maintenance, of electronic, fiber, phone and data cabling, connections, and equipment for such cabling, conduits, transmitters, receivers, and other office, computer, communications and word and data processing cable, equipment and facilities, subject to Landlord’s right to require any vendor, contractor or service provider of Tenant to execute Landlord’s then commercially reasonable form of license agreement or access agreement permitting such vendor, contractor or service provider access to such portions of the Building for purposes of installing the applicable cabling, wiring and/or equipment.
(ii)    Tenant shall permit Landlord to install, use and maintain pipes, ducts and conduits within the walls, columns and ceilings of the Premises, provided that the same shall not interfere with Tenant’s then-existing installations, interfere with Tenant’s use and operation of the Premises for the Permitted Use or create any violation of the conditions of Tenant’s operating licenses, or reduce the usable floor area by more than a de minimis amount or change the interior configuration of the Premises by more than a de minimis amount.
(iii)    Landlord reserves the right, without incurring any liability to Tenant therefor, to make such changes in or to the Building and the fixtures and equipment thereof, as well as in or to the street entrances, halls, passages, elevators, stairways and other improvements thereof, as it may deem necessary or desirable.
(iv)    Landlord may adopt any name for the Building and Landlord reserves the right to change the name or address of the Building at any time.
Y.    IDENTIFICATION OF TENANT.
(1)    If Tenant constitutes more than one person or entity, (A) each of them shall be jointly and severally liable for the keeping, observing and performing of all of the terms, covenants, conditions and provisions of this Lease to be kept, observed and performed by Tenant, (B) the term “Tenant” as used in this Lease shall mean and include each of them jointly and severally, and (C) the act of or notice from, or notice or refund to, or the signature of, any one or more of them, with respect to the tenancy of this Lease, including, but not limited to, any renewal, extension, expiration, termination or modification, of this Lease, shall be binding upon each and all of the persons or entities executing this Lease as Tenant with the same force and effect as if each and all of them had so acted or so given or received such notice or refund or so signed.
(2)    If Tenant is a general partnership (or is comprised of two or more persons, individually and as co-partners of a general partnership) or if Tenant’s interest in this Lease shall be assigned to a general partnership (or to two or more persons, individually and as co-partners of a general partnership) pursuant to Article 16 hereof (any such partnership and such persons hereinafter referred to in this Article 30.Y. as “Partnership Tenant”), the following provisions of this Lease shall apply to such Partnership Tenant:
(A)    The liability of each of the parties comprising Partnership Tenant shall be joint and several.
(B)    Each of the parties comprising Partnership Tenant hereby consents in advance to, and agrees to be bound by, any written instrument which may hereafter be executed, changing, modifying or discharging this Lease, in whole or in part, or surrendering all or any part of the Premises to the Landlord, and by notices, demands, requests or other communication which may hereafter be given, by the individual or individuals authorized to execute this Lease on behalf of Partnership Tenant under Article 30.B. above.

Z.    ANTI-TERRORISM REPRESENTATION. MAKE MUTUAL

(1)     Each party certifies to the other that:

(a)    It is not acting, directly or indirectly, for or on behalf of any person, group, entity, or nation named by any Executive Order or the United States Treasury Department as a terrorist, “Specially Designated National and Blocked Person,” or other banned or blocked person, entity, nation, or transaction pursuant to any law, order, rule, or regulation that is enforced or administered by the Office of Foreign Assets Control; and

(b)    It is not engaged in this transaction, directly or indirectly on behalf of, or instigating or facilitating this transaction, directly or indirectly on behalf of, any such person, group, entity, or nation.

(1)    Tenant will not use the assets of an employee benefit plan as defined in Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”) and covered under Title I, Part 4 of ERISA or Section 4975 of the Internal Revenue Code of 1986, as amended, in the performance, discharge or satisfaction of any of its obligations under this Lease such that it would constitute a “prohibited transaction” under ERISA.      Notwithstanding any provision of the Lease to the contrary, Tenant shall not assign the Lease or sublease all or any portion of the Premises unless (i) such assignee or subtenant delivers to Landlord a certification (in form and content satisfactory to Landlord) with respect to the status of such assignee or subtenant (and any guarantor of such assignee’s or subtenant’s obligations) as a party in interest and a disqualified person, as provided above; and (ii) such assignee or subtenant undertakes not to take any action that would cause the Lease to constitute a non-exempt prohibited transaction under ERISA.

(2)    Notwithstanding any provision of the Lease to the contrary,  Tenant shall not (i) sublease all or any portion of the premises under a sublease in which the rent is based upon the net income or net profits of any person or (ii) enter into any other transaction with respect to the Lease or the Premises such that the revenues to be received by Landlord from time to time in connection with the Lease would, as a result of such transaction, be subject to Unrelated Business Income Tax under Section 511 through 514 of the Internal Revenue Code of 1986, as amended.

(3)    Tenant agrees that it shall incorporate these requirements in any sublease of the Premises.

ARTICLE 31.

RIGHT OF FIRST OFFER

A.    Provided that this Lease is in full force and effect and that no default (continuing uncured beyond the expiration of applicable notice and cure periods) shall exist under this Lease both at the time of Tenant’s exercise of the ROFO (as hereinafter defined) and on the date of entry into the agreement incorporating the Offered Space (as hereinafter defined), Tenant shall have a one (1)-time right (except as otherwise provided in Article 31.C. below) (the “ROFO”), at the expiration of the term of the first lease entered into with a bona fide third party tenant in respect of the ROFO Space (as hereinafter defined) (the parties acknowledging and agreeing that, as of the date of this Lease, the ROFO space is not leased to any other tenant and thus is not yet “available” to Tenant under this Article 31), to lease all or any portion of the thirteenth (13th) floor of the Building (the “ROFO Space”) on the first (1st) occasion that such ROFO Space “becomes available.”  For purposes of this Article 31, the ROFO Space shall be deemed to “become available” if and only if Landlord, following the date of this Lease, has first leased the ROFO Space to a bona fide third party tenant and such third party’s lease or other occupancy agreement with respect to the ROFO Space subsequently expires or is otherwise terminated.

B.    Notwithstanding anything set forth in this Article 31 to the contrary, the ROFO Space shall not be deemed to “become available” if the ROFO Space is:

(i)    Assigned or subleased by the then current tenant of the ROFO Space (following Landlord’s initial leasing of the ROFO Space as provided above) as to which Tenant was afforded notice as provided herein; or

(ii)    Re-leased by such then current tenant of the ROFO Space by renewal, extension, or renegotiation (whether or not an express renewal option is afforded to such tenant under the terms of its lease); or

(iii)    Not leased to a tenant as of the date of this Lease (until that space is leased, and then subsequently “becomes available,” as provided above); or

(iv)    Subject to an existing (as of the date of this Lease) right of first offer, right of first refusal or other expansion right of another tenant in the Building, the parties acknowledging and agreeing that, as of the date of this Lease, only Fish & Richardson P.C. has a superior right of first offer with respect to the ROFO Space; or

(v)    Subject to a holdover by the then current tenant of the ROFO Space.

C.    Subject to the foregoing, the first time during the Term that Landlord proposes to offer for lease all or any portion of the ROFO Space which Landlord anticipates will “become available,” Landlord shall furnish to Tenant a notice (the “First Offer Proposal”) containing the material terms of the proposed lease in respect of the applicable portions of the available ROFO Space (the “Offered Space”), including (i) a floor plan of the Offered Space, (ii) annual base rent for the Offered Space, (iii) the proposed effective date of the lease for the Offered Space, and (iv) any other material terms which Landlord shall deem appropriate.  Tenant shall have the option, exercisable by notice delivered to Landlord within ten (10) days after Tenant’s receipt or refusal of receipt of Landlord’s First Offer Proposal, TIME BEING OF THE ESSENCE, to lease the Offered Space upon such terms and conditions as are contained in the First Offer Proposal.  If Tenant timely delivers to Landlord written notice of Tenant’s exercise of the ROFO for the Offered Space, then, within ten (10) business days thereafter, the parties shall enter into a commercially reasonable amendment to this Lease incorporating the Offered Space as part of the Premises on the terms and conditions contained in the First Offer Proposal and for the then remaining term of this Lease (provided, however, that at least three (3) full years would remain on the Term following the effective date of Tenant’s lease of the Offered Space, whether in the ordinary course or a result of Tenant’s exercise of a then available extension option in accordance with the terms and conditions of this Lease).  If Tenant declines or fails to timely exercise the ROFO with respect to the Offered Space, Landlord shall thereafter be free, for a period of one hundred eighty (180) days after the expiration of the ten (10) day ROFO exercise period referenced above, to lease the Offered Space (and any other portion of the ROFO Space, if applicable) without regard to the restrictions contained in this Article 31 and on such terms and conditions as Landlord may decide in its sole discretion, so long as each material term (as hereinafter defined) of such third party lease is no more than ten percent (10%) more favorable to such third party tenant than each corresponding material term set forth in the applicable First Offer Proposal (on a line item basis).  The following shall constitute “material terms” under this paragraph: (1) base rent, (2) term (including extension, renewal, expansion and early termination rights), (3) free rent (inside the term), (4) operating expenses and (5) tenant improvement allowance.  If no such third party lease for the Offered Space shall be concluded within said one hundred eighty (180) day period, then the provisions of this paragraph shall again be applicable to the Offered Space.

D.    The ROFO is personal to Tenant and shall become null and void upon the occurrence of an assignment of the Lease or subletting of all or any portion of the Premises in accordance with the terms of this Lease, except in connection with a Permitted Transfer.
 

IN WITNESS WHEREOF, and intending to be legally bound hereby, the parties have duly executed this Lease with the Exhibits attached hereto, as of the day and year first written above.

Exhibit A 
 
Space/Floor Plan Showing Premises

Exhibit B
Tenant’s Work Exhibit
1.    (a)    Tenant shall, at Tenant’s expense, submit to Landlord final and complete dimensioned and detailed plans and drawings of partition layouts (including openings), ceiling and lighting layouts, colors, mechanical and electrical circuitry plans and any and all other information as may be reasonably necessary to complete the construction of the Premises in accordance with this Exhibit B (such plans are collectively referred to herein as “Tenant’s Plans”).  The partition layout, and ceiling and lighting layout plans shall be 1'0” = 1/8” scale.  Tenant shall submit Tenant’s Plans and any other plans required by this Exhibit B to Landlord in form, quality and quantity acceptable for the purposes of filing for a building permit with the Inspectional Services Department of the City of Boston (“ISD”), and such plans shall be signed and sealed by an architect licensed in the Commonwealth of Massachusetts.

(b)    Landlord shall not unreasonably withhold, delay or condition its approval of Tenant’s Plans. Landlord shall approve Tenant’s Plans as soon as reasonably possible or designate by notice to Tenant the specific changes required to be made to Tenant’s Plans, which Tenant shall make within three (3) business days of receipt.  This procedure shall be repeated until Tenant’s Plans are finally approved by Landlord.

(c)    Any architect or designer acting for or on behalf of Tenant shall be deemed an agent of and authorized to bind Tenant in all respects.

(d)    All plans, drawings and specifications with respect to the Premises required to be submitted by Tenant to Landlord shall comply with and conform to the Building plans filed with the ISD, Building standard specifications (the receipt of which Tenant hereby acknowledges) and with all the rules, regulations and/or other requirements of any governmental department having jurisdiction over the construction of the Building and/or Premises.  Tenant shall prepare drawings in accordance with pre-existing conditions and field measurements.

(e)    Landlord’s review of Tenant’s Plans is solely to protect the interests of Landlord in the Building and the Premises, and Landlord shall be neither the guarantor of, nor responsible for, the correctness or accuracy of Tenant’s Plans, or the compliance of Tenant’s Plans with applicable requirements of any governmental authority.  Landlord’s review and approval of any submissions shall not be deemed to be an approval of the adequacy for any particular purpose or system capacity or the cost of the Tenant Improvements. 

(f)    Tenant shall reimburse Landlord for all actual, out-of-pocket costs incurred by Landlord in connection with having third parties review all submissions, plans and specifications submitted to Landlord for its review and approval pursuant to this Exhibit B, subject to the Allowance; provided that Tenant shall in no event be required to reimburse Landlord more than $2,500 on account of such review costs (and no costs reimbursed hereunder shall be duplicative of costs reimbursed under the Lease).

2.    (a)    Tenant shall, at its expense (except for the Allowance), in accordance with the terms and conditions of this Exhibit B, be responsible for the construction of all improvements and alterations necessary to prepare the Premises to conform with Tenant’s Plans (the “Tenant Improvements”).  The term “Substantial Completion” shall mean when Tenant has obtained a temporary or final certificate of occupancy from ISD with respect to the Premises as improved in accordance with the terms and conditions of this Exhibit B.  After completion of Tenant’s Plans, Tenant shall submit Tenant’s Plans to the appropriate governmental body for plan checking and a building permit.  Tenant shall deliver a copy of the building permit to Landlord prior to the commencement of construction of the Tenant Improvements.  Tenant shall not make any material changes to Tenant’s Plans once finally approved by Landlord without Landlord’s consent.

(b)    Tenant shall select a contractor (the “Contractor”), subject to the approval of Landlord, which approval will not be unreasonably withheld and shall be granted or denied within 15 calendar days of request for such approval. With its request for approval of the Contractor, Tenant shall furnish to Landlord such information concerning the proposed Contractor’s background and experience as Landlord may reasonably require.  A price for a construction contract based on Tenant’s Plans shall be mutually agreed upon by Tenant and the Contractor. Tenant shall enter into an agreement with the Contractor to build the Tenant Improvements, at Tenant’s sole cost, except for the Allowance.  

The construction contract will provide for progress payments, no more frequently than once per calendar month, in minimum increments of $25,000.00, and each progress payment will be funded as follows: Landlord will fund the percentage of each progress payment equal to a fraction expressed as a percentage, the numerator of which is the Allowance and the denominator of which is the total cost of the Tenant Improvements; and Tenant will fund the remainder.  Ten percent (10%) of each progress payment shall be retained by Landlord until Tenant delivers, or causes to be delivered, to Landlord a certificate of occupancy or certificate of completion, in form and substance reasonably satisfactory to Landlord, with respect to the Premises together with final and unconditional waivers of mechanic’s liens concerning the work for all labor and services performed and all material furnished in connection with the work, signed by the Contractor and all subcontractors, suppliers, and laborers involved in the work.  Notwithstanding anything contained herein or in the Lease to the contrary, Landlord shall have no obligation to disburse any portion of the Allowance during any period of time that Tenant is in default of its obligations under the Lease (continuing uncured following receipt of notice thereof from Landlord) or upon or following termination of the Lease.

(c)    If the cost of the design and construction of the Tenant Improvements is less than the Allowance, the difference shall be retained by Landlord. In the event that Tenant requests any changes to Tenant’s Plans, Landlord shall not unreasonably withhold, delay or condition its consent to any such changes, provided the changes do not adversely affect the Building’s structure, systems, equipment or appearance.  

(d)    The Allowance will be applied to the design and construction of the Tenant Improvements and for no other purpose.  The “Allowance” shall be an amount equal to the product of (i) the area of the Premises in rentable square feet and (ii) $70.00.  All costs attributable to the Tenant Improvements in excess of the Allowance shall be paid for by Tenant.

3.    (a)    Before beginning the Tenant Improvements, Tenant shall pay for and deliver to Landlord satisfactory evidence of the insurance coverage(s) required to be maintained by Tenant under Article 8 of the Lease.  Landlord and the Contractor shall be named as additional insureds in such liability policies or certificates of insurance and the same shall remain in effect during the period of the performance of the Tenant Improvements.  

(b)    All the Tenant Improvements shall be in accordance with the Project Documents and the rules and regulations of any governmental department or bureau having jurisdiction thereover and shall not conflict with, or be in violation or cause any violation of, Landlord’s basic Building plans and/or the construction of the Building, and all the Tenant Improvements shall be completed free of all liens and encumbrances.  All permits which may be required by Tenant for the Tenant Improvements shall be procured and paid for by Tenant or, if Landlord shall deem the same advisable, Landlord may procure such permits and Tenant shall pay for the same.  No plans and/or specifications required to be filed by Tenant pursuant to any work contemplated to be performed by it within the Premises shall be filed or submitted to any governmental authority having jurisdiction thereover without first having obtained Landlord’s approval of same.

(c)    Upon completion of the Tenant Improvements, Tenant will remove all debris and excess materials from the Building and the Premises.

(d)    Without limiting the applicability of Article 5.E. of the Lease, the labor employed by Tenant or the Contractor shall always be harmonious and compatible with the labor employed by Landlord or any contractors or sub-contractors of Landlord.  Should such labor be incompatible with such Landlord’s labor as shall be determined by the sole judgment of Landlord, to be exercised in good faith, Landlord may require Tenant to withdraw from the Premises until the completion of the Building and/or Premises by Landlord.

(e)    In the event Tenant or the Contractor shall enter upon the Premises or any other part of the Building, as may be permitted by Landlord, Tenant shall indemnify and save Landlord free and harmless from and against any and all claims arising from or out of any entry thereon or the performance of the Tenant Improvements and from and against any and all claims arising from or claimed to arise from any act or neglect of Tenant or Tenant’s representatives or from any failure to act, or for any other reason whatsoever arising out of said entry or such work.  

(f)    Tenant Improvements which Landlord reasonably determines are specialized to Tenant’s use and occupancy of the Premises, including, without limitation, wiring and cabling, shall, at the election of Landlord (which election shall be made in writing at the time of Landlord’s approval of Tenant’s Plan hereunder), either (1) be removed by Tenant at its expense before the expiration or earlier termination of the term of the Lease or (2) remain upon the Premises and be surrendered therewith without disturbance, molestation or injury upon the expiration or earlier termination of the Lease.  If Landlord requires the removal of all or part of the specialized Tenant Improvements, Tenant, at its expense, shall repair any damage to the Premises or the Building caused by such removal.  If Tenant fails to remove any specialized Tenant Improvements upon Landlord’s request, then Landlord may (but shall not be obligated to) remove the same and the cost of such removal and repair of any damage caused by the same, together with any and all damages which Landlord may suffer and sustain by reason of the failure of Tenant to remove the same, shall be charged to Tenant and paid upon demand.  

4.    In no event shall Tenant be eligible to receive or entitled to any credit for any portion of the Allowance not used by Tenant by July 31, 2016.  Tenant shall be responsible for the maintenance, repair and replacement of all Tenant Improvements unless the same is necessitated by the negligent acts of Landlord.
5.    Tenant hereby authorizes Timothy Betjemann as Tenant’s representative to act on its behalf and represent its interests with respect to all matters which pertain to the construction of Tenant Improvements, and to make decisions binding upon Tenant with respect to such matters.  Landlord hereby authorizes Richard Martini to be Landlord’s representative in connection with construction of the Tenant Improvements.  Tenant hereby expressly recognizes and agrees that no other person claiming to act on behalf of the Landlord is authorized to do so, and any costs, expenses liabilities or obligations incurred or paid by Tenant in reliance on the discretion of any such other person shall be Tenant’s sole responsibility.
6.    In the event of a conflict between the terms and provisions of the Lease and the terms and provisions of this Exhibit B, the terms and provisions of this Exhibit B shall control.

Exhibit E 
 
Description of Base Building Condition

Exhibit F

Option to Extend Term
(a)    Tenant shall have and is hereby granted the option to extend the Term of the Lease of the entire Premises (the “Extension Option”) for one (1) additional period of five (5) years (the “Extension Period”), provided that: (i) Tenant gives written notice to Landlord of Tenant’s election of interest to exercise the Extension Option no later than fifteen (15) months prior to the Expiration Date (“Tenant’s Notice to Extend”); and (ii)  no event of default exists and is continuing uncured (following notice to Tenant) at the time of the exercise of the Extension Option, or arises subsequent thereto and is not cured prior to what otherwise would have been the commencement of the Extension Period.

(b)    All terms and conditions of this Lease, including without limitation all provisions governing the payment of Additional Rent, shall remain in full force and effect during the Extension Period, except that the Base Rent payable during the Extension Period shall be the then-current fair market rental rate for comparable office space in Boston at the time of the exercise of the option granted herein, taking into consideration all relevant factors (the “Current Market Rental Rate”), but in no event less than the fully-escalated Base Rent and Escalation Increases in effect for the last Lease Year of the Term, and the Base Year shall be the calendar year in which the Extension Period commences.

(c)    Landlord shall notify Tenant of Landlord’s proposed Base Rent for the Extension Period within thirty (30) days after Landlord’s receipt of Tenant’s Notice to Extend.  Promptly after Landlord gives Tenant Landlord’s proposal for Current Market Rental Rate with respect to the Extension Period, Landlord and Tenant shall commence negotiations to agree upon the Current Market Rental Rate.  If Landlord and Tenant are unable to reach agreement on the Current Market Rental Rate within thirty (30) days after the date on which Landlord gives Tenant Landlord’s proposal for Current Market Rental Rate, then the Current Market Rental Rate shall be determined as provided below.

(d)    If Landlord and Tenant are unable to agree on the Current Market Rental Rate within said thirty (30) day period, then within five (5) days thereafter, Landlord and Tenant shall each simultaneously submit to the other in a sealed envelope its good faith estimate of the Current Market Rental Rate.  If the higher of such estimates is not more than one hundred five percent (105%) of the lower of such estimates, then the Current Market Rental Rate shall be the average of the two (2) estimates.  If the matter is not resolved by the exchange of estimates or averaging, then Current Market Rental Rate shall be determined as hereinafter provided.

(e)    Within seven (7) days after the exchange of estimates, the parties shall select, as an arbitrator, a mutually acceptable commercial real estate broker licensed in the Commonwealth of Massachusetts as a real estate broker specializing in the field of commercial office leasing in the downtown Boston rental market, having no less than ten (10) years’ experience in such field (an “Approved Broker”).  If the parties cannot agree on such person, then within a second (2nd) period of seven (7) days, each shall select an Approved Broker and within a third (3rd) period of seven (7) days, the two (2) appointed persons shall select a third (3rd) Approved Broker and the third (3rd) person shall be the arbitrator.  If one (1) party shall fail to make such appointment within said second seven (7) day period, then the person chosen by the other party shall be the sole arbitrator.  Once the 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 Current Market Rental Rate by selecting either the Landlord’s estimate of Current Market Rental Rate or the Tenant’s estimate of Current Market Rental Rate. There shall be no discovery or similar proceedings and the arbitrator shall have no power or authority to make any independent determination.  The arbitrator’s decision as to which estimate of Current Market Rental Rate shall be the Current Market Rental Rate for the Extension Period shall be rendered in writing to both Landlord and Tenant and shall be final and binding upon them and shall be the Base Rent for the Extension Period.  The costs of the arbitrator will be equally divided between Landlord and Tenant.  Any fees of any counsel engaged by Landlord or Tenant, however, shall be borne by the party that retained such counsel.

(f)    The parties shall execute an amendment modifying this Lease to set forth the Base Rent for the Premises during the Extension Period within ten (10) business days following the parties’ agreement or, in the alternative, within ten (10) business days following the arbitrator’s determination, of the Base Rent for the Extension Period, but the failure to do so shall have no effect on Tenant’s otherwise valid and timely exercise of the Extension Option.

(a)    Lender will not name Tenant as a party to any judicial or non-judicial foreclosure or other proceeding to enforce the Mortgage unless joinder is required under applicable law but in such case Lender will not seek affirmative relief against Tenant, the Lease will not be terminated and Tenant’s possession of the Leased Space will not be disturbed;
